INTRODUCTION A. History of Municipal Service Reviews In 1997, Assembly Bill (AB) 1484 established the Commission of Local Governance for the 21st Century. The role of the Commission of Local Governance was to evaluate local government organization and operational issues and develop a statewide vision and determine how the State should grow. The Commission in their final report identified four critical findings, as follows:  The future will be shaped by continued phenomenal growth;  California did not have a plan for growth;  Local Government budgets are perennially under siege;  The public is not engaged. Within this framework, the Local Governance Commission concluded that Local Agency Formation Commission’s (LAFCO’s) powers should be expanded and be a participant in regional growth and planning forums. Further, the Local Governance Commission recommended that State law be amended to require that spheres of influence be regularly updated and that LAFCO’s initiate periodic regional municipal service reviews, also known as service area plans, to ensure the efficient provision of governmental services. A sphere of influence is defined by law as a “…plan for the probable physical boundaries and service area of a local agency, as determined by the Commission” (GC 56076). As a result of the Local Governance Commission’s recommendations, on September 26, 2000, Governor Gray Davis signed into law AB 2838, titled the Cortese-Knox-Hertzberg Local Government Reorganization Act. The Cortese- Knox-Hertzberg Act requires each LAFCO to review and update as necessary the spheres of influence for all applicable agencies within each County. In Imperial County, service area plans are recommended to be updated every five years in order to be in compliance (Governor’s Office of Planning and Research, LAFCO Municipal Service Review Guidelines). B. Purpose of the Service Area Plan Service area plans are intended to assess current service demand and future service needs within an agency’s sphere of influence, and demonstrate that future public facilities, for the provision of services, have been identified in accordance with the Cortese-Knox-Hertzberg Act. Service area plans provide each LAFCO with a tool to comprehensively study existing and future public service 1 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND conditions and to evaluate organizational options for accommodating growth, preventing urban sprawl, preserving open space and prime agricultural lands, and efficiently extending government services. The City of Imperial Service Area Plan will provide the Imperial County Local Agency Formation Commission with a detailed description and analysis of how facilities will be provided in the proposed sphere of influence. C. Requirements of a Service Area Plan The requirements of the contents of an up to date service area plan are determined by the State’s Government Code. Per Government Code Section 56430, LAFCO shall prepare a written statement of its determinations with respect to each of the following plan requirements: 1. Growth and population projections for the affected area. 2. Present and planned capacity of public facilities and adequacy of public services, including infrastructure needs or deficiencies. 3. Financial ability of agencies to provide services. 4. Status of, and opportunities for, shared facilities. 5. Accountability for community service needs, including governmental structure and operational efficiencies. 6. Any other matter related to effective or efficient service delivery, as required by commission policy. D. Role of the Imperial County Local Agency Formation Commission The Imperial County Local Agency Formation Commission (IC LAFCO) is charged with the review and approval of the City of Imperial Service Area Plan. The Imperial County LAFCO is comprised of two County Supervisors appointed by the Board of Supervisors, two City Council members appointed by the City Selection Committee, and one public member approved by LAFCO, for a total of five members. LAFCO has the authority to review, approve, or deny boundary changes, city annexations, consolidations, special district formations, incorporations for cities and special districts, and to establish local spheres of influence. The Imperial County LAFCO responded to the new mandates of AB 2838 by adopting State Municipal Service Review Guidelines from the Governor’s Office of Planning and Research (OPR) as the Imperial County LAFCO’s new Service Area Plan Guidelines. Imperial County LAFCO requires a service area plan be approved prior to approval of a sphere of influence amendment and/or annexation. Imperial County LAFCO must be able to ascertain that there will be sufficient public facilities within the requested sphere of influence or annexation consistent with the following: 2 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND a) In conducting a service review, the Commission shall comprehensively review all of the agencies that provide the identified service or services within the designated geographic area. b) The Commission shall conduct a service review before, or in conjunction with, but no later than, the time it is considering an action to establish a sphere of influence in accordance with Section 56425 or Section 56426.5 or to update a sphere of influence pursuant to Section 56425. E. Current Status of the City of Imperial Service Area Plan The last City of Imperial Service Area Plan (SAP) was prepared in 2007 by Howes, Weiler & Associates and was adopted by LAFCO on June 26, 2008. Since its adoption, there have been some modest changes in growth projections and facility improvements. The 2007 data had made some aggressive growth projections, and thus service demand was projected to be higher. This demand has since been modestly adjusted as presented herein. There are some modest changes to growth patterns within the proposed service areas. This new updated Service Area Plan provides a more current analysis of existing public facilities and services of the City of Imperial and indicates how the demand created by future developments within the City’s service area would be met for each service and facility. II. BACKGROUND A. Geographic Location The City of Imperial is a predominantly agricultural community situated 13 miles north of the U.S./Mexico border and is located in Imperial County. The City encompasses approximately 5.85 square miles and is adjacent to the northern boundary of the City of El Centro. State Route 86 serves the entire Imperial County, traverses the City of Imperial at a north/south orientation, and functions as the Town’s main arterial. The City is home to many important operations including the Imperial County Airport, the Imperial Irrigation District Headquarters, and the El Centro Sector Headquarters of the U.S. Border Patrol, all of which contribute to employment opportunities and demand for housing thus impacting growth and service demand. Exhibit 1-City of Imperial Geographic Location, illustrates the regional location of the City of Imperial in relation to the rest of Imperial County. 3 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND Exhibit 1- City of Imperial Geographic Location 4 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND A. City Limits and Existing Sphere of Influence The legal City limits is uniquely shaped and may be generally described as bound by Treshill Road to the south (excluding a small area just south of the Aten Road & Clark Road intersection), extending west to Austin Road and northerly up to Ralph Road closer along Highway 86 in an irregular pattern, and easterly in the same diversified manner. The adopted Sphere of Influence follows a similar pattern, prioritizing growth areas to the east (refer to Exhibit 2 – City Limits and Sphere of Influence Boundaries). The entire 2014 Sphere of Influence consisted of approximately 7,507 acres of land, 3,855 of which are within the City limits. There are some minor boundary changes proposed under this 2015 Service Area Plan Update as can be depicted in the same Exhibit 2-City Limits and Sphere of Influence Boundaries. The changes are described first as the inclusion of a sparsely developed area west of the City limits between Austin Road and the City’s western legal boundary line. This area encompasses approximately 811 acres of low density residential, and is further discussed in the City’s Planned Annexation areas at a 20 year horizon. The second change involves the inclusion of two vacant sites totaling 210 acres one of which is northeast of the City and a second along Dogwood Road both of which will allow for continuity in future annexations, within a twenty (20) year horizon. The final change involves the elimination of a 145 acre area located at the southeast intersection of Aten Road and Dogwood Road, (previously known as Castle Arch). The resulting final Sphere of Influence boundary map is noted as Exhibit 2A 2015 Sphere of Influence & City Limits. The final 2015 Sphere of Influence boundaries would encompass a total of 8,383 acres. The City of Imperial’s ultimate goal and service area boundary is proposed to extend easterly to Highway 111 as depicted in Exhibit 2B Planned 2020 Sphere of Influence. This Service Area Plan will take into consideration facility demands into the expanded areas up to Highway 111 as planned expansion. B. Population and Demographics The City of Imperial has the highest growth rate in the County (54.3 % since 2006 per the California Department of Finance). Based on population data available from the US Census Bureau and the State Department of Finance, the City of Imperial has experienced an aggressive population growth over the last couple of decades when taking into account growth trends since 1990. The City of Imperial was incorporated in July 12, 1904, had a population of 4,413 by 1990 and by 2014, had an estimated population of 16,708. From 1990 to 2010, the City had the highest growth in Imperial County, growing at an average annual growth rate of 12.94 percent compared to Imperial County as a whole which experienced an average growth rate of 2.99 percent for the same time period. 5 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND Exhibit 2 – City Limits and Sphere of Influence Boundaries 6 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND Exhibit 2A– 2015 Sphere of Influence Boundary & City Limits 7 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND Exhibit 2 B– 2020 Planned Sphere of Influence 8 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND Figure 1-A Depicts historic Population growth within the incorporated city limits in five year increments and as of January 2015.

Another significant factor contributing to the population growth may be attributed to population demographics. Over 74 percent of the Imperial population is Latino, according to US Census figures. Culturally, Latinos tend to share households with extended family members. The City’s average household size of 3.35 persons per household is significantly larger than the State’s average household size at 2.90 persons per household (US Census, 2010). These statistics are important in determining what the service needs of the population are. There is a vibrant population outlook associated with new development planned within the City’s Sphere of Influence. Imperial’s service area, and thus potential growth areas, are comprised of relatively large tracts of vacant, low-priced farmland that has captured the market interest of residential developers. Imperial is also near the Imperial Valley Community College, which serves the entire region, and which along with its centralized location in the County, make Imperial an attractive location for residential, commercial, and industrial development. These factors and planned annexations highlight the importance of planning services and facilities to adequately serve the projected population. It is projected that by 2035 the City’s population will be 26,923 (Source: Southern California Association of Governments 2012-2035 Regional Transportation Plan) and up to 62,541 when considering planned annexations. Population trends and projections are further discussed under Growth and Phasing Projections. 9 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND B. City of Imperial Operations, Public Facilities and Services The administrative offices of the City of Imperial are located at 420 South Imperial Avenue, and serve a constituency of approximately 4,859 persons (Imperial County Elections Office, January 2012). The governing structure consists of a five-member City Council elected by the public. A City Manager reports directly to the City Council and is charged with overseeing the City’s operation and employees. The City also has a legal counsel that reports to the Council and the City Manager. The City currently operates with 87 employees and had a 2014/2015 fiscal year General Fund budget of approximately $8,551,547 and Enterprise Funds for Water ($4,439,500) and Wastewater ($3,415,567), for a total budget of $14,620.252 (Source: City of Imperial Adopted Municipal Budget FY 2014-2015). The City of Imperial provides a full range of public services including administration, storm-water and drainage, fire protection, police protection, public library services, parks and recreation, transportation/circulation facilities, sanitary sewer and domestic water. Wastewater collection and treatment services and potable water treatment and distribution services by far demand the highest capital investment within the City’s service area. Having a comprehensive and reliable Service Area Plan is of utmost important for orderly growth and development. The City’s Mission Statement is “To promote and provide for the safety, health and welfare of our citizens and business community, it is the Mission of the City of Imperial through its elected officials, appointed officials, employees and volunteers to:  Provide customer service in a professional, cost-effective and innovative manner, consistent with the values of integrity, teamwork, stewardship, competence, politeness and respect.  Provide land use planning direction that preserves City heritage and quality of life while promoting community improvement and economic development.  Commit appropriate revenues to fund innovative, high quality, cost-efficient City programs and services while maintaining adequate reserves for unforeseen event or opportunities.  Regularly evaluate City programs and services and revise them when appropriate.  Seek the involvement of citizens in City government and planning, and foster civic leadership. 10 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN INTRODUCTION & BACKGROUND III. ORGANIZATION AND STRUCTURE OF SERVICE AREA PLAN This Service Area Plan discusses the services currently provided by the City of Imperial, estimates the current and future demand for such facilities and services, and describes how necessary facilities and services will be, or may be, developed or improved on to meet population demands. The intent of the Service Area Plan is to demonstrate the City’s ability to provide adequate services within the sphere of influence boundaries in the event of new development with the City Limit or new annexations into the Sphere of Influence. An approximate 20-year planning period is used to forecast growth and the estimated facility and service demands are based on population projections in five-year increments until 2035. This document complies with the requirements of Section 56653(b) regarding the preparation of a plan for providing services (Service Area Plan) and provides the information necessary for LAFCO to conduct a municipal services review in compliance with Section 56430. This Service Area Plan document is further organized into the following six sections that satisfy the Guidelines adopted by the Imperial County LAFCO: INTRODUCTION AND BACKGROUND: Provides a brief description of the City of Imperial as well as the general characteristics of the community and Service Area Plan requirements, including overall content of the Service Area Plan. EXECUTIVE SUMMARY: Provides a brief summary of the services assessment and conditions identified in the plan and highlight critical information regarding existing facilities, demand, mitigation, their costs, and anticipated methods of financing. LAND USES IN ANNEXATION AREAS & GROWTH PROJECTIONS: Provides a discussion on existing and planned land uses in the City’s Sphere of Influence and describes potential impacts associated with population growth and projected service demand. BUILDOUT/PHASING PROJECTIONS: Provides a discussion on build-out phasing projections within the 20-year planning period. The intent of this section is to provide an additional planning tool that may allow the City to anticipate future public facility needs and to budget monies for any identified improvements. PUBLIC FACILITIES AND SERVICES: Provides a thorough description of current and planned facilities and services, and its current and projected adequacy. The following facilities and services are included in the review: I. Administrative Facilities II. Stormwater & Drainage Facilities III. Fire Protection Facilities IV.

In addition, this section would identify cost saving opportunities in shared facilities. 12 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN EXECUTIVE SUMMARY EXECUTIVE SUMMARY This Executive Summary provides a brief summary of the population projections to provide a context for the analysis and findings presented for each individual public facility in terms of the performance standard, existing facilities, existing facility demand versus anticipated future demand and its adequacy, mitigation, funding sources, annual budget and cost per capita. I. POPULATION PROJECTIONS This Service Area Plan uses population projections based on the recent and anticipated annexations, as provided in the Growth Projections section of this document. The City of Imperial’s January 2015 population was 17,313 and estimated to increase to just under 49,000 by 2025 and is expected to grow to just over 62,500 by the year 2035 when taking into account approved and planned development and not just a historic growth rate. The following table, City of Imperial Population Projections, projects the future population of the City of Imperial through Year 2035 in five year increments under both scenarios.

Orderly development is accomplished through planned improvements, phasing of service expansions and phasing of development projects. This section of the Service Area Plan identifies the existing land uses, the availability of land, the planned land uses, and the anticipated population growth which are all critical factors on how the City will service the community. I. LAND USES AND ANNEXATION AREAS A. Land Uses A land use survey was conducted for all areas within the City Limits and within the City’s Sphere of Influence in 2014 during the City’s Housing Element Update for the assessment of potential residential land use development opportunities. This document incorporates those land use findings and an inventory of additional non- residential land use designations available for development. The current City of Imperial General Plan land use designations were used to determine the available acreage, the future development potential for all vacant and underutilized land, and ultimately growth projections. Please Refer to Exhibit 3 - General Plan Land Use Map, which depicts the City’s adopted land use designations. Findings determined that within the established City of Imperial Sphere of Influence, there is ample opportunity for land development. Approximately 4,488 acres are vacant and undeveloped in potential annexation areas in addition to the 979+ acres of undeveloped land or land under development that currently exists within the City Limits of which 640+ can support residential land uses. It is important to note that a number of developable areas are classified as Specific Plan Areas. Specific Plan Areas allow for a more comprehensive approach to land use planning. The purpose of the specific plan is the systematic implementation of the general plan for all, or part, of the covered area by the general plan and pre-determines zoning prior to annexation. At least two Specific Plans have been recently prepared and approved by the City of Imperial for service consideration. Table G-2 Developable Land by Land Use distributes this acreage to specific land use designations as adopted under the General Plan and further accounts for these Service Area Plan areas and the remaining acreage for development. 23 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Exhibit 3 - General Plan Land Use Map 24 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Table G-2 Developable Land by Land Use Acres Acres Total Acres Land Use Designation Within Outside City in Service City Limits Limits/SOI Area Residential Rural 129 0 129 Residential Low Density 0 811 811 Residential Single Family 263 2,050 2,313 Residential Condominium 0 0 0 Residential Apartment 8 0 8 Mobile Home Park 6 0 6 Planned Unit Development/PUD 50 0 50 Specific Plan Area 185 0 185 Agricultural 0 1,132 1,132 Village Commercial 4+ 0 4 Commercial Neighborhood 84+ 140 224+ General Industrial 100+ 0 100+ Rail Served Industrial 150+ 355 505+ TOTALS 979+ 4,488 5,467 Source: City of Imperial General Plan Land Use Map used for Land Use Designations and Google Earth used for Acreage calculations. B. Land Use Restrictions Land Use restrictions are a significant factor affecting population growth and service demand. The City’s residential land use designations provide for a wide range of development opportunities including single-family dwellings, mobile homes, manufactured housing, condominiums, multi-family units. These opportunities are offered at various densities, and include mixed use development (commercial/residential) for areas in the downtown Village Commercial Zone. The following table identifies the densities per acre which are allowed for each land use designation: Table G-3 -Land Use Designation Build Out Density GENERAL PLAN VACANT BUILD DWELLING UNITS OUT DENSITY LAND USE DESIGNATION PER ACRE RANGE PER ACRE Residential Rural 0.5 – 1.0 1 Residential Low Density 1.0 – 2.0 2 Residential Single Family 2.0 – 6.0 6 Residential Condominium 5.0 – 30.0 20 Residential Apartment 20.0 – 30.0 20 Mobile Home Park 7.0 7 Agriculture .4 .4 Source: City of Imperial Zoning Ordinance, 2014 25 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS C. Annexation History & Developable Land in Incorporated Areas The City experienced significant annexations during the housing boom of the 2000’s. The City’s most recent annexation dates back to 2007 at which time 188 acres designated for residential land uses were annexed into the City associated with the Morningstar development. Other recent annexation history includes the following:  2007 Morningstar Annexation- Consisted of approximately 598 detached single family units and was approximately zero (0) percent built out as January 2015.  2005 Mayfield Annexation- Consists of 168 lots approved of which forty (40) percent were built out as of January 2015. These annexations contribute to the available developable land and/or land under development within the incorporated City Limits. Other areas within the incorporated City Limits under development include Monterrey Park (Residential Single Family) and Victoria Ranch (Residential Single Family/Specific Plan Overlay). There are also over eight (8) acres of Residential Apartment and over 125 acres of Residential Rural available throughout the incorporated city limits for in-fill development. Table G-2 previously identified the total acreage by land use which includes all these discussed areas. It is assumed that all these developable areas within the incorporated City Limits will be built out within the next fifteen years and has a projected population of 9,025 when multiplying 2,694 anticipated units by the average household size of 3.35 persons per household (pphh).

D. New Annexation Areas Outside of the current City limits there are a total of eleven 11 areas assumed for potential annexation and development within the next twenty (20) years. These areas are further noted in Exhibit 4-Planning Period Annexation Areas which illustrates the location of these annexation areas. 26 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Exhibit 4-Planning Period Annexation Areas 27 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS The proposed annexation areas are further summarized under Table G-5 City of Imperial Annexation Areas.

Phasing of Development The Phasing of annexation areas provides a pattern and estimate for where and when development within the areas of annexation will be phased into the City of Imperial. This projection provides City leadership with a phased estimated growth that can be strategically planned for. For the purpose of this assessment it was determined to combine growth areas per five year increments. Although phasing is difficult to predict with precision, projecting is beneficial for the planning of public facilities to ensure that the level of service standards are continually met. It becomes more difficult to predict phasing beyond the ten year mark, thus in summary most of the residential growth was projected within the ten year plan or at twenty years. The phasing, acreage, and realistic residential units of all planned development is further summarized under Table G-6 by annexation area and phasing term. 35 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Table G-6 Annexation Areas as Phased Residential Units Development/ Realistic Area Acres Phasing General Land Use Units ¹ N-3 Regional Park & Equestrian 144 1 year 0 Center/ Recreational Park N-4 Barioni Lakes Phase I/ 186 1 year 701 Residential & Commercial SE-1 Encanto Estates/ 320 1 year 99 Agriculture & Commercial N-5 HBC/ 163 5 years 16 Agriculture & Industrial NE-2 Sanchez Ranch/ 620 5 years 867 Ag, Residential, & Commercial SE-2 East Annexation/ 84 5 years 0 Industrial SE-3 Crown Commercial/ 310 5 years 1,488 Residential Subtotal 1,827 5 Years 3,171 N-1 Barioni Lakes North/ 370 10 years 1,488 Residential & Commercial N-2 Barioni Lakes West/ 390 10 years 1,872 Residential NE-1 McFarland Ranch/ 320 10 years 99 Agriculture & Commercial SE-5 NE Corner of Cross & Aten/ 320 10 years 1,488 Residential & Commercial SE-6 South of Aten/East of RR Tracks/ 160 10 years 0 Industrial Subtotal 1,560 10 Years 4,947 W-1 Western Development/ 891 20 years 1,681 Residential N-6 West Neckel Development/ 50 20 years 240 Residential SE-4 Andalusiaa East/ 160 20 years 768 Residential Subtotal 1,101 20 Years 2,689 GRAND TOTAL 4,488 10,807 ¹Methodology: The acreage in each development was multiplied by the maximum density allowed for the corresponding land use and by 80% to discount roadways, parks and retention basins and get realistic units. 36 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS II. GROWTH PROJECTIONS Annexation, thus growth, is influenced by land use restrictions, existing conditions, and availability of service at developable locations. The location of the development is typically market and public improvement cost driven. The City of Imperial has undertaken several initiatives to encourage development including the adoption of one of the lowest development impact fees in the County. In July 2004, the City also passed a Planned-Unit Development Ordinance to further encourage infill development. The City also attracts development into the community by providing a high level of customer service and an efficient project review process. The proceeding sections provide an overview of the City’s land use restrictions and growth projections for development areas. A. Maximum Land Use Densities As previously noted, the growth projections in the proceeding sections have assumed the maximum densities allowed. Additionally an 80% realistic maximum development ratio has been applied for population projections. This discounted density is a conservative calculation in order to discount for land areas that will not have residential use because those areas more than likely that will be used for public improvements such as roadways, parks, retention basins, and other similar facilities that impact the developable land ratio. B. Residential Growth Projections The residential growth projections provide the anticipated future residential development based on the most current land use designations and their allowable densities as previously discussed. The land use designations for the Sphere of Influence are based on the current City of Imperial General Plan, as shown by Exhibit 3 - General Plan Land Use Map on page 24, as well as the development proposed for the annexation areas. An average household size of 3.35 persons per household was used to calculate population projections from any given total number of dwelling units. Base information was obtained from assessor parcel maps, the City of Imperial General Plan, an on-site land use survey, the California Department of Finance and building permit information through December 2014 as referenced below. 1. Existing Dwelling Units in SOI All the existing dwelling units within the sphere of influence were determined by 2010 Census base numbers and subsequent building permits through December 2014 for the incorporated City limits. The existing dwelling units included single family detached dwellings, mobile homes and multi-family residential units. It was determined that there were 5,168 existing dwelling units within the City limits as of December 2014. The corresponding population is 17,313 persons. It was also determined in the 37 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS 2007 Service Area Plan that there were a total of 58 existing dwelling units in the annexation areas within the Sphere of Influence, excluding the W-1 Western Development not previously accounted for as an annexation area. Based on the 2007 City of Imperial Service Area Plan, and no new residential development within the unincorporated areas, and the estimated existing population of 1,222 in the now planned for W-1 Western Development Annexation Area (365 units x 3.35 pphh), a total of 5,591 existing dwelling units are estimated within the entire Sphere of Influence area as of December 2014, as summarized in the table below, for an estimated population of 18,729.

Future Dwelling Units in SOI Future dwelling units were calculated by adding the number of vacant and underutilized acres for sites both within the incorporated City Limits and in Annexation Areas, grouped into land use, and multiplying that summation by the allowed density per acre (Vacant Build Out Density) and applying the 80% realistic maximum build-out as a conservative ratio. The formula used to obtain this figure is as follows: (Developable Acres¹ x Vacant Build Out Density) x 80% = Realistic Future Dwelling Units ¹Developable Acres is Vacant & Underutilized Acres Based on the density allowances and the annexation assumptions in this report, and as depicted in Table G-8 Future Dwelling Units, the incorporated areas could accommodate approximately 2,694 additional residential units and the annexation areas could accommodate approximately 10,807 including existing development within unincorporated area. The total additional future dwelling unit count for all areas within the City limits and the annexation areas is estimated to be 13,501 additional units as noted in the table below for an estimated population growth of 45,228 by year 2035. 38 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Table G-8 Future Dwelling Units Residential Phasing Future Units Future Units Realistic Land Uses Inside City Annexation Future Limits Areas1 Units Residential Single Family 5 Years 420 2,909 3,329 Agriculture 5 Years 0 262 262 Village Commercial 5 Years 40 0 40 Subtotal 5 Years 460 3,171 3,631 Residential Single Family 10 Years 421 4,848 5,269 Agriculture 10 Years 0 99 99 Residential Apartment 10 Years 128 0 128 Planned Use Development 10 Years 240 0 240 Subtotal 10 Years 789 4,947 5,736 Residential Single Family 15 Years 421 0 421 Mobile Home Park 15 Years 33 0 33 Residential Rural 15 Years 103 0 103 Specific Plan 15 Years 888 0 888 Subtotal 15 Years 1,445 0 1,445 Residential Low Density 20 Years 0 1,297 1,297 Residential Single Family 20 Years 0 1,392 1,397 Subtotal 20 Years 0 2,689 2,689 Grand Total 2,694 10,807 13,501 1Realistic Units in Annexation areas includes the 423 existing units in the annexation areas, as noted in Table G-7 3. Build Out Dwelling Units in SOI Combining the existing dwelling units (5,591) and projected future dwelling units (13,501), and discounting the existing units in the annexation area (423) from projected future dwelling units, results in a total build out dwelling unit projection of 18,669 dwelling units for the entire Sphere of Influence by1 2035, as summarized in Table G-9 - Build-Out Dwelling Units. The build out population for vacant parcels within the incorporated City limits is 9,025. The build-out population for vacant parcels within the annexation areas is 36,203. The build out units for the City of Imperial once all areas within the sphere of influence have been annexed and developed is estimated to total 13,501, (the combination of existing units, build out of incorporated areas, and build out of annexation areas provides a grand total of 18,669 units or 62,541 persons based on 3.35 persons per household). Table G-10 Build-Out Population Projections summarizes the build-out dwelling units and corresponding populations in five year increments. 39 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Table G-9 Build-Out Dwelling Units Existing Realistic Build-Out Residential Land Uses Dwelling Units SOI Future Dwelling Entire SOI Dwelling Units Units Entire SOI Residential Low Density 365 932 1,297 Residential Single Family 4,587 10,353 14,940 Residential Multi-Family 542 0 542 Residential Condominium 63 0 63 Agriculture 0 361 361 Mobile Home Park 34 33 67 Village Commercial 0 40 40 Residential Rural 0 103 103 Residential Apartment 0 128 128 Planned Use Development 0 240 240 Specific Plan 0 888 888 Totals 5,591 13,078 18,669 The 423 Existing Dwelling Units in the Annexation Areas, as noted in Table G-7 – Existing Dwelling Units, are included in the Existing Dwelling Units Entire SOI and discounted from Realistic SOI Future Dwelling Units to prevent double counting.

The population projections that follow are based on historic population growth rates in comparison to growth tied to anticipated projects. For the Imperial population projections, a growth rate of 2.23 percent has been determined as adequate. This growth rate is a modest rate to apply to the projected population growth for the Imperial community for the entire twenty (20) year planning period analyzed under this Service Area Plan. Planned development as noted in the prior discussions may significantly alter these population growth projections. Projections are therefore discussed as probable scenarios affecting service demand assuming maximum growth scenario thus planned development. 40 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS Figure G-1 – Population Projections for the City of Imperial depicts a gradual population growth of 2.23 percent that would reasonably place the Imperial population at 26,923 at the 20 year mark and compares it to population growth with approved and planned development. If there are changes in the real estate market and the regional development demand increases, the City will likely be directly impacted by new growth and expansion outside of the current City boundary within the Sphere of Influence and more in line with the aforementioned approved and planned development projections and reach 62,541 at the end of the twenty year plan period.

Non-Residential Development Non-residential projects also impact most community facilities and services. Non- residential projects include government operations, industrial, business/office use, and commercial land uses. Non-residential development is first calculated in square footage and commonly converted into Equivalent Dwelling Units for the purpose of assessing demand on facilities such as wastewater and water. The methodology for obtaining existing and future non-residential square footage is similar to that of the residential projections in that a coverage factor is assigned. 41 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS a). Existing Non-Residential Square Footage in City Limits The nonresidential square footage within the City limits was estimated to be 4,132,793 square feet in 2007. Since then, and over a five year period, a total of 47,158 square feet of commercial and industrial space has been constructed within the incorporated City Limits, per City of Imperial building permit records. This number represents .01% of the total non-residential square footage at the beginning of that time period. The existing non-residential square footage within the City Limits is currently estimated at 4,179,951 square feet. b). Existing Non-Residential Square Footage in Annexation Areas The nonresidential square footage within the annexation areas was estimated to be 397,449 square feet in 2007. Since then, an estimated total of 50,427 square feet of commercial and industrial space has been constructed within the Annexation areas (Imperial County Building Permit Records), thus the existing nonresidential square footage within the annexation areas is currently estimated at 447,876 square feet. 1. Future Non-Residential Growth Projections The vacant coverage factor for commercial and industrial uses for future development is 30%. The reason for the reduction from 40% for existing development to future development is that a coverage factor of 30% accounts for reductions of buildable land area for street and utility land dedications, as well as parking and landscaping requirements that essentially decrease the amount of square footage that can be developed. a). Future Non-Residential Square Footage in City Limits The future nonresidential square footage within the City limits was estimated to be 10,181,031 square feet under the 2007 Service Area Plan. Considering no changes in zoning to affect this estimate, and deducting the 47,158 square feet of commercial space constructed since then, it is estimated that 10,133,873 of future non-residential square footage should be planned for b). Future Non-Residential Square Footage in Annexation Areas The future nonresidential square footage within the annexation areas was estimated to be 10,651,712 square feet under the 2007 Service Area Plan. At the direction of the City, an increase adjustment was made in 2015 to increase the amount of non-residential development along major arterial intersections. These changes resulted in a square footage base number of 11,344,826 square feet. Since the Castle Arch Annexation was removed, which accounted for 84,942 square feet of planned commercial and an additional 50,427 square feet of commercial and industrial space have further been constructed within the unincorporated sphere of influence (as per Imperial County Building permits), a total of 135,369 square feet were deducted from the 11,344,826 to give an 42 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS estimated total of 11,209,457 of future non-residential square footage within the annexation areas to be planned for. 2. Build-out Non-Residential Projections Combining the existing nonresidential inventory with the future nonresidential projections, the total nonresidential build out projections were determined. The total build-out non-residential square footage within the sphere of influence including all existing square footage is estimated to be 25,971,157 square feet as denoted in the following tables.

All calculations done in square feet. 3. Equivalent Dwelling Unit Phasing of Non-Residential Development Non-residential uses need to be converted to “equivalent dwelling units” for the purpose of preparing a comprehensive analysis. This assessment is applying 1.5 EDU’s for every 1,000 square feet of non-residential space. This number is an unscientific average and the City of Imperial, adopted Resolution 90-16, should be referred to for a more precise assignment of equivalent dwelling units for non-residential land uses (for the purpose of assessing impacts to wastewater and water facilities). A very conservative assumption is further being made that the non-residential development within the City Limits will develop at an average of 1% of planned commercial space for every five year period. The following Table G-12 projects the timing of non-residential development in five year increments and the corresponding conversion into equivalent dwelling units (1.5 43 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LAND USE IN ANNEXATION AREAS & GROWTH PROJECTIONS EDU’s per every 1,000 SF of nonresidential space) for the same time periods.

An analysis of the following facilities and services are provided in this document:  Administrative Facilities - City of Imperial  Drainage Facilities - City of Imperial/Imperial Irrigation District  Fire Protection Facilities - County of Imperial (via contract)  Police Protection - City of Imperial  Library Facilities - City of Imperial  Park and Recreational Facilities - City of Imperial  Circulation Facilities - City of Imperial  Sanitary Sewer Facilities - City of Imperial  Domestic Water Facilities - City of Imperial Each facility is analyzed in detail based on the standards developed by LAFCO for Service Area Plans. Each facility analysis is divided into four sections as follows: Performance Standard: A description of the desired level of service that a public facility must provide. Facility Planning and Adequacy Analysis: A description of the existing facilities, the current adequacy of the facilities, the future demand for facilities and the phasing of the demand for facilities as follows:  Inventory of Existing Facilities  Inventory of Approved Facilities  Growth Demand for Facilities  Buildout/Phasing of Facilities Mitigation: A series of recommendations to ensure that adequate facilities will be provided. Financing: An explanation and identification of how the service and facilities are currently being funded, including a per capita cost, and how future services and facilities may be funded. Each section will provide a description of the nature of each service to be provided, a description of the service level capacity and demonstrate that adequate services will be provided within the demanded time frame. Presentations of maps that clearly indicate the location of existing and proposed facilities are provided for each facility. Discussion of any conditions which may be imposed or required within the affected territory are also noted. 46 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN ADMINISTRATION I. ADMINISTRATION City of Imperial administrative facilities include City Hall and office buildings that house administrative staff and provide general administrative services to Imperial residents and the business community. Examples of administrative services include utility billing and collection, clerk services, planning and development services and other administrative functions of the City. A. Performance Standard The performance standard for administrative services was determined during the preparation of the Service Area Plan approved by LAFCO on January 25, 2001. It was based on the existing administrative facilities square footage and the existing population at the time of the preparation of the Service Area Plan. It was determined at that time that the building area available was efficient and appropriate. Therefore, the performance standard was set at 842 square feet per 1,000 in population. B. Facility Planning and Adequacy Analysis This analysis provides an inventory of the existing City Administrative Facilities owned by the City of Imperial, the existing and future demand for facilities as well as a projected phasing schedule. The purpose of this analysis is to determine if the existing facilities are adequate for the existing and future demand, and if not adequate, to identify approximately when additional facilities will be needed in order to meet future demand identified within the 20 year time frame. 1. Inventory of Existing Facilities The City of Imperial City Hall is located at 420 South Imperial Avenue. The existing administrative facilities consist of a total of 9,888 square feet and centrally located as noted in Exhibit 5-Administration Facilities Map. This square footage is broken down into the following categories: Table-A-1 Administration Facilities City Clerk 306 SF City Hall 2,523 SF City Manager 866 SF Legislative 1,000 SF Community Center 2,568 SF Parks & Recreation 288 SF Senior Center 2,337 SF Total 9,888 SF 47 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN ADMINISTRATION Exhibit 5- Administration Facilities 48 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN ADMINISTRATION 2. Adequacy of Existing Facilities The City has $200,000 budgeted for City Hall Improvements over the next three years. Funds, however, are to improve existing facilities and not for expansion beyond the currently available 9,888 SF. Using the performance formula provided below, the existing demand for administrative facilities is 14,577 square feet. Existing Population x Performance Standard = Current Demand 17, 313 Population x 842 Sq. Ft / 1,000 population = 14,577 Sq. Ft. Existing Facilities – Current Demand = Adequacy 9,888 Sq. Ft. – 14,577 Sq. Ft. = -4,689 Sq. Ft. Based on the performance standard formula, there is a deficiency of 4,689 square feet of administrative building square footage. As the population increases, there will be an inherent need for additional City administrative facilities. 3. Future Demand for Facilities For the purpose of calculating future demand, and as previously noted, planned development is used to project population. Using the existing performance standard formula, the City of Imperial will need 52,659 square feet of administrative space by the year 2035 if all development is constructed as planned. When using solely the historical growth rate, the demand for administrative facilities could be reduced to 22,669 square feet for 2035. 4. Opportunities for Shared Facilities The City of Imperial provides for all of its City administrative needs using full-time, part-time and contract workers. Assistance from other jurisdictions for administrative services is not provided nor will be provided, but cross-utilization of services within the jurisdiction is facilitated. There are many staff members who provide their expertise in public facilities and services that are outside of the administrative services arena such as in circulation, water and wastewater. For example, the City Manager, Community Development Director and several other employees of the City will complete tasks that are not a part of the administrative services, but are directly related to the specific needs of various public services that the City provides. These tasks are funded through the individual budgets of the various departments for which the tasks are being completed. This method of cross-utilization is an efficient use of existing resources especially for 49 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN ADMINISTRATION small jurisdictions such as the City of Imperial. 5. Phasing The following Table A-2 Administration Facilities Demand represents the demand for administrative facilities square footage for the next 20 years in five year increments. The population noted is using planned development for projections. Table A-2 Administrative Facilities Demand Year Population Demand Adequacy 2020 29,476 24,818 SF Deficient 2025 48,692 40,998 SF Deficient 2030 53,533 45,074 SF Deficient 2035 62,541 52,659 SF Deficient C. Mitigation On a yearly basis, the City of Imperial should review the facilities provided against the demand for facilities based on the performance standard. Additional facilities should be planned for and provided on an as needed basis. The City should implement the following mitigation measures for administrative facilities: A-1 On a yearly basis, the City of Imperial shall review the facilities provided against the demand for facilities based on the performance standard. A-2 By the year 2025 (10 year time period), a minimum of 35,186 additional square feet of administrative facilities shall be provided to meet demand through 2030. D. Financing Information regarding Project costs was determined by using the most current adopted budget (See Appendix A). The current revenue source for administrative facilities includes property tax and sales taxes, licenses and permits, fine and penalties, charges for services, Development Impact Fees and other miscellaneous sources. 1. Funding Sources and Per Capita Cost The 2014-2015 City of Imperial Budget identifies approximately $4,107,978 for the continued operation of administrative facilities. 50 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN ADMINISTRATION There are approximately $1,786,660 in functional revenues (charges for services, licenses) used to help pay for the administrative services. These functional revenues must be subtracted from the expenditures in order to determine the true costs to the general public. Therefore, the cost to the general public through taxation for administrative services is $2,321,318. $2,321,318 / 17,313 population = $134.08 per capita Using the City’s current population, and a constant per capita cost of $134.08, the future costs are noted in the following table in five year increments. These estimations assume a constant cost per capita in the year 2014 dollars and the provided population projections. Table A-3 Projected Administrative Costs Year Projected/Planned Administrative Costs Population 2020 29,476 $3,952,126.69 2025 48,692 $6,528,597.94 2030 53,533 $7,177,676.69 2035 62,541 $8,385,497.28 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources for the maintenance and operation of City administrative facilities. However, due to the future growth anticipated, other funding sources for capital improvements will be needed. Other funding sources that may be available for capital improvements include general obligation bonds or a City wide community facilities district. Further descriptions of the financing mechanisms are provided in the Financing section of this Service Area Plan. 51 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER II. DRAINAGE AND STORMWATER The primary purpose of maintaining, planning, designing and constructing drainage facilities is to control flooding. Drainage facilities in the entire Imperial Valley are within the jurisdiction of the Imperial Irrigation District (IID). In conjunction with an irrigation network that includes more than 1,600 miles of canals, IID operates and maintains an agricultural drainage system consisting of more than 1,400 miles of surface drains. The City of Imperial discharges into IID drains which ultimately drain into the Alamo River, a tributary to the Salton Sea. It should be noted, however, that the primary drainage system managed by IID is not designed to convey all stormwater runoff from urbanized areas. Therefore, new development must provide for on-site retention of stormwater to mitigate against stormwater impacts. A. Performance Standard Adequacy of drainage facilities is based on conformance with the City of Imperial design guidelines for storm water runoff and management. Conformance with the City’s NPDES requirements, the requirements of the Federal Emergency Management Agency and the requirements established by the Imperial Irrigation District for storm water runoff are also applicable. B. Facility Planning and Adequacy Analysis The City of Imperial’s stormwater drainage facilities include many ditches, pipes and detention basins which function to divert storm runoff and standing water away from residences and business within the City. These facilities convey storm water runoff into the main water drainage system managed by the Imperial Irrigation District (IID). However, the IID has communicated interest in abandoning all facilities within the City limits for the City to take over the system. Additionally, as future development occurs and drainage facilities are no longer used for agricultural drainage, the IID will abandon those facilities to the City, so that the IID only manages drains used for agricultural. 1. Inventory of Existing Facilities A majority of the storm water collected within the City of Imperial uses surface drainage ditches to convey storm water to the IID drains. The primary drainage facilities receiving the City of Imperial’s storm water, and managed by the Imperial Irrigation District, include the North Central Drain, North Central Drain No. 2, Newside Drain No. 1, Dahlia Drain No. 8, Dolson Drain No. 2 and the McCall Drain No. 5A and 5B. There are five primary drainage zones that tie into these drains as depicted in Exhibit 6-Drainage Zones and Retention Facilities. 52 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER Exhibit 6-Drainage Zones and Retention Facilities 53 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER The five primary drainage zones within the City can be geographically described as southwestern portion (SW), central west portion (CW), central east portion (CE), eastern portion (E), and northeast portion (NE). The zones are described in more detail below. SW Drainage Zone: The southwestern portion of the City near the Sandalwood and Wildflower subdivisions and the industrial area at Aten and La Brucherie use a series of retention basins to restrict the flow of storm water before entering the underground storm water conveyance pipes. There is a small lift station adjacent to Aten Road, which assists with the conveyance of storm water for the Sandalwood and Wildflower subdivisions into the storm water conveyance system. The system then transports the storm water to the North Central Drain No. 2 which ultimately flows to the main North Central Drain. CW Drainage Zone: The central portion of the City, north of the airport and west of Highway 86, conveys storm water through surface drainage ditches to a primary surface drainage ditch located adjacent to Highway 86. This drainage ditch flows north adjacent to Highway 86 to the IID Dahlia No. 8 drain. CE Drainage Zone: The central area east of Highway 86 and west of the railroad tracks also uses surface drainage ditches to convey storm water to a primary drainage ditch adjacent to M Street. The M Street drainage ditch flows north to Fifteenth Street. At Fifteenth Street, the M Street ditch storm water enters the IID Dolson No. 2 Drain. E Drainage Zone: From First Street to Barioni Boulevard east of the railroad tracks, surface drainage ditches convey storm water to an IID drainage pipe at the southeast corner of the intersection of Barioni and P Street. North of Barioni Boulevard, surface drainage ditches convey stormwater west to the primary drainage ditch at Barioni Boulevard and N Street. The N Street drainage ditch flows north to Fifteenth Street. At this point the surface water flows into an 18" pipe which conveys the stormwater west under the railroad tracks and into the IID Dolson No. 2 Drain. NE Drainage Zone: There are two subdivisions in the northern portion of the City east of Highway 86. Each subdivision contains their respective retention basins and underground stormwater conveyance systems. Water flows out of the retention basins and into the IID Dolson No. 8 and No. 2 Drains. 54 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER 2. Adequacy of Existing Facilities The existing primary drainage system managed by IID is not designed to convey all storm water runoff from urbanization. Therefore, recent and new development must provide for on-site retention of storm water to mitigate against storm water impacts. These retention facilities are designed to control storm water flows into the IID drains. Conveyance out of the retention basins is restricted by the use of 12" pipes. The City of Imperial Public Works Department provides the maintenance of the City storm water drainage system. The public works crews monitor the flow within the drainage ditches, make minor repairs and clean the ditches on an as needed basis. Additionally, street sweeping occurs throughout the City, which is a preventative method that assists in keeping the drainage ways clean of some debris and sediment. According to the City of Imperial Public Works Director, Jackie Loper, the current system provides adequate conveyance of storm water for events up to a100-year storm. There were only two instances in the mid - 1970's when the drainage system did not adequately convey storm water in localized low-lying areas. 3. Future Demand for Facilities As future development occurs, storm water drainage systems must be installed into the project area to ensure adequate collection and conveyance of runoff. The type and extent of the development proposed will affect the demand of facilities. A significant increase in the amount of impervious surfaces will result in a greater amount of surface runoff. The exact size and location of future facilities will be determined at the time development is proposed and processed through the City of Imperial. All future development must continue to comply with IID policies regarding temporary retention of storm water to reduce the impacts to the IID drains. Storm water runoff as well as other contributing factors has degraded both the New and Alamo Rivers. The recently updated Water Quality Control Plan for the Colorado River Basin Region prepared by the California Regional Water Quality Control Board contains strict requirements for the water quality conveyed into these rivers. Future facilities must be designed to adhere to the latest pollution control devices and NPDES requirements. 4. Opportunities for Shared Facilities The City of Imperial maintains all storm drain facilities within the incorporated City limits using full-time and part-time staff. Assistance 55 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER from other jurisdictions for drainage services is not provided or necessary beyond the maintenance provided by IID for IID Drains. The City of Imperial and IID maintain different aspects of the total drainage system. As previously noted, the primary drainage system is managed by IID but it is not intended to convey storm water generated by urban runoff. However, some urban storm water does flow into the IID drainage system. At this time, the management of these facilities is effective and is not expected to change in the near future. 5. Phasing The construction of future storm water drainage facilities is based on the rate of new development within the City of Imperial. Additional storm water drainage facilities will be needed in the proposed annexation areas in order to convey storm water into the IID drainage system. The future storm water management systems for the annexation areas will be designed during the Tentative Map and Final Map stage of development. C. Mitigation The City of Imperial should continually monitor the existing storm drain facilities to ensure the facilities are operating at an adequate level. Specifically, the City should implement the following mitigation measures for drainage facilities: D-1 All future development in the City of Imperial shall be required to construct storm drain facilities in accordance with the design standards of the Engineering Department and the IID necessary to convey storm water into existing drains managed by IID. D-2 All future development shall retain storm water on-site or within existing retention basins to restrict storm water flow for a minimum period of 72 hours before discharging into IID facilities. D-3 All future development shall ensure compliance with all local, state and federal rules and regulations related to the discharge of storm water. D-4 All development shall provide improvements constructed pursuant to best management practices as referenced in the California Storm Water Best Management Practices Handbook. 56 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER D. Financing Future storm water drainage facilities will be installed at the developer’s expense at the time of project construction. Maintenance of existing and future public drainage facilities will be financed by the City of Imperial General Fund. 1. Funding Sources and Per Capita Costs The current revenue sources for storm water drainage facilities include property and sales taxes, licenses and permits, charges for services and other miscellaneous sources. The City of Imperial’s annual budget does not segregate out the maintenance and operation costs for storm drain facilities. Thus, the maintenance and operation costs of the storm water drainage system could not be accurately determined. However, based on information provided by the City Public Works Department, it is estimated that approximately $34,505 per year is spent on maintenance and operation costs. The amount fluctuates depending on the amount of rain that is received on any given year. Since the City of Imperial’s annual budget does not segregate out the maintenance and operation cost for storm drain facilities, the average per capita cost for the continued maintenance and operation of the storm water drainage system was determined by the City’s current population and estimated $34,505 per year amount for maintenance and operation. The per capita cost for drainage facilities is assumed to be $1.99. $34,505 / 17,313 population = $1.99 per capita A cost estimate for future continued maintenance and operation of the storm water drainage facilities is provided in Table D-1-Drainage Facilities Costs. These estimations assume a constant cost per capita in the year 2014 - 2015 dollars and the provided population projections. 57 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DRAINAGE & STORMWATER Table D-1-Projected Drainage Facilities Costs Year Projected/Planned Drainage Facility Costs Population 2020 29,476 $58,657.24 2025 48,692 $96,897.08 2030 53,533 $106,530.67 2035 62,541 $124,456.59 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources for the maintenance and operation of City storm water drainage facilities which include property and sales taxes, licenses and permits, charges for services and other miscellaneous sources. However, due to the future growth anticipated, other funding sources for capital improvements will be needed. The City collects development impact fees; however, there is currently no impact fee for drainage facilities. Other funding sources that could be made available are a City wide community facilities district, special assessment districts or a community services district. Further descriptions of these and other financing mechanisms are provided in the Financing section of this Service Area Plan. 58 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION III. FIRE PROTECTION Fire protection services are provided to the City of Imperial by the Imperial County Fire Department (ICFD). The City of Imperial contracts with the County of Imperial for fire protection and emergency services in accordance with the Agreement for Fire Protection Services Between County of Imperial and City of Imperial (July June 18, 2014). The current agreement is effective until June 30, 2017 (See Appendix B). The ICFD maintains and operates five (5) fire stations throughout the County of Imperial. Imperial is serviced by Imperial County Station #1-4. The County Station #1-4, servicing the City of Imperial, is located at the Imperial County Airport grounds. A. Performance Standard The Imperial County Fire Department informally monitors the demand on fire protection facilities and services. The fire department has consistently provided response times of 3 to 5 minutes for medical emergencies and 4 to 7 minutes for structural fires. Therefore, the performance standard necessary to maintain the current level of service shall not exceed a response time of 5 minutes for medical emergencies and 7 minutes for structural fires. Additionally, the Agreement for Fire Protection Services states that fire protection service will be provided to the City of Imperial on a twenty-four (24) hour, seven (7) day a-week basis. Additionally, the NFPA Standard for Firefighters is set at one firefighter per 1,000 residents. B. Facility Planning and Adequacy Analysis The areas currently served by the ICFD include both the areas within the City limits and the annexation areas. The County fire department will continue to provide service to these areas. 1. Inventory of Existing Facilities The City of Imperial is served by the one fire station located at 2514 La Brucherie Road. The fire station has 14,500 square feet of building area. There are currently 3 firefighters (one of which must be a paramedic) on duty each shift. In addition, there is one (1) reserve firefighter on call at night. In accordance with the Agreement for Fire Protection Services, three (3) full-time Captains, three (3) full-time Fire Fighters II, and three (3) reserve firefighters are assigned to the City 24 hours per day. The same agreement further commits the following fire protection equipment and facilities for availability to Imperial:  One (1) 500 gallon Engine (City Owned)  One (1) 500 gallon Engine/105 ladder truck (City Owned) 59 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION  One (1) 1,000 gallon Engine (County)  One (1) 1,800 gallon Water Tender (County)  One (1) 2,500 gallon Water Tender (County)  One (1) 1,500 gallon Aircraft Crash/Rescue Truck (County)  One (1) Medium Rescue Squad (County)  One (1) Hazardous Device (Bomb) Unit (County) As shown on EXHIBIT B of the Agreement for Fire Protection Services, the City of Imperial also owns some of the equipment at the fire station. Minor preventative maintenance of the equipment and management of the personnel are performed by the County. Major repairs to equipment are the responsibility of the City of Imperial. 2. Adequacy of Existing Facilities The fire department currently provides average response times of 7 minutes for the Northeast area (Neckel Road), 3 minutes for the Southwest area (Aten/Austin), 5 minutes for the Northwest area (14th/D Street), and 5 minutes for the Southeast area (Clark/Aten). However, as development continues to occur, there may be occasional delays due to traffic. A shared facility for police protection and fire protection is planned at the northeast corner of Clark Road and Worthington Road to further minimize response times east of the railroad tracks. An alternative site has also been designated on Aten Road between P Street and Dogwood Road. Please refer to Exhibit 7- Existing and Proposed Fire Station Facilities for a depiction of the regional location of the existing fire station and proposed location of future facilities. 3. Future Demand for Facilities The City is estimated to reach a population of 62,541 by the year 2035. Based on the demand projections provided in this service area plan, it is apparent that another fire station is needed. A master plan for fire protection facilities has not been prepared by the fire department and future needs for additional firefighting equipment and another fire station have yet to be fully determined. However, there are preliminary indications that a shared fire/police substation is desired. This public safety facility is anticipated to be approximately 15,000 square feet and to include training facilities to be shared by the fire and police departments. It is assumed that the fire department will utilize approximately 10,000 square feet of the facility. Based on the current development trend toward the east, the new public safety facility may be located at the northeast corner of Clark Road and Worthington Road as denoted in Exhibit 7. 60 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION Exhibit 7- Existing and Proposed Fire Station Facilities 61 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION 4. Opportunities for Shared Facilities The County of Imperial, through the office of the County Fire Chief, provides to the City of Imperial fire protection and emergency medical services. The fire station located in the City of Imperial is owned by the county as well as most of the firefighting equipment. However, the City owns a 1,250 gallon pumper and various firefighting equipment. All facilities are used jointly in order to provide an adequate level of service for both the county and City area. There is also the Imperial Valley Fire Service and Rescue Mutual Aid Plan in place to ensure that emergency needs will be met. The intent of the mutual aid plan is to meet the anticipated needs of local agencies within their zones, to access resources of adjacent agencies within the area of the County, and to access the resources of other jurisdictions within Region VI or beyond, if necessary, to meet the needs of emergency incidents. 5. Phasing As the City’s population increases, additional fire department staff can be hired when necessary in order to meet the demand created by future development. The following Table F-1 Projected Fire Service Demand represents the demand for fire protection services for the next 20 years in 5 year increments. Table F-1 Projected Fire Service Demand Year Projected/Planned Fire Service Demand1 Population 19,500 SF Facility 2020 29,476 29 Firefighters/3 Paramedics 19,500 SF Facility 2025 48,692 48 Firefighters/3 Paramedics 19,500 SF Facility 2030 53,533 53 Firefighters/3 Paramedics 19,500 SF Facility 2035 62,541 62 Firefighters/3 Paramedics 1Square footage demands based on need to meet required response times, as derived from City of Imperial 2007 Service Area Plan. C. Mitigation The City of Imperial and the County fire department should continually monitor the existing fire department facilities and response times to ensure that adequate fire protection is provided. In accordance with the agreement for fire protection services, the county provides the City with monthly reports concerning all incidents occurring during the month and the maintenance/condition of all City owned equipment. Additionally, the County Fire Chief and the Imperial City Manager 62 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION are required to meet on a quarterly basis to discuss fire related issues. Mitigation recommended is as follows: F-1 Fire protection facilities and personnel should be incrementally added as demand increases. F-2 An additional fire station should be proactively planned for. F-3 All major developments proposed within the City of Imperial shall be forwarded to the fire department for review and comments. F-4 Adequate fire flows shall be provided for all development projects. F-5 A Master Plan for Fire Protection Facilities to address development east of the railroad tracks should be prepared prior to the expiration of the current fire protection services contract (June 30, 2017). D. Financing The City of Imperial contracts with Imperial County for fire protection and emergency medical services. The City of Imperial currently has no plans to change the fire protection services as provided by the Imperial County Fire Department. A yearly fee amount is paid to the County for these services. According to the Agreement for Fire Protection Services Between County of Imperial and City of Imperial, the fiscal year 2014-2015 fee was estimated at $896,699. The current revenue sources for fire protection services include property and sales taxes from the City’s general fund. A new agreement will be needed by June 30, 2017. 1. Per Capita Costs For the fiscal year 2014-2015, the City of Imperial has budgeted $894,000 for fire protection services. Using the City’s estimated 2015 population of 17,313, fire protection service per capita cost for the 2014-2015 fiscal year is $51.63 per resident. This data was calculated by dividing the annual budget of the fire department by the existing population. $894,000 / 17,313 residents = $51.63 per capita The Agreement for Fire Protection Services identifies estimated costs of $869,699 for the 2014-2015 fiscal year through the 2015-2016 fiscal year. A cost estimate for future fire protection services is provided in the table below using the budgeted amount and per capita cost of $51.63 per resident. 63 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FIRE PROTECTION Table F-2 Projected Fire Service Costs Year Projected/Planned Fire Service Cost Population 2020 29,476 $1,521,845.88 2025 48,692 $2,513,967.96 2030 53,533 $2,763,908.79 2035 62,541 $3,228,991.83 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources of property and sales tax, including development impact fees, and continue the contracting of fire protection services through the Imperial County Fire Department. Other funding sources that may be available in the future include a Fire Suppression Assessment, formation of a Citywide Community Facilities District, or grant funding. Further descriptions of these and other financing mechanisms are provided in the Financing section. 64 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION IV. POLICE PROTECTION Police services are provided to the Imperial community by the Imperial Police Department. The police station is located at 424 S. Imperial Avenue in Imperial which is the main headquarters. The Imperial Police Department provides services to the entire City of Imperial. The City of Imperial Police Department also assists the County Sheriff’s Office if the County does not have an officer in the vicinity. The Imperial Police Department will also provide backup for the County Sheriff if necessary. Services in the City of Imperial include patrol, criminal investigations, civil services, and crime prevention. A. Performance Standard The performance standard for police protection and law enforcement facilities was determined upon approval of the 2001 service area plan. The performance standard is 1.6 officers per 1,000 population, 2 officers per 1 patrol vehicle, 0.25 Non-paid volunteers per 1,000 population, and 237 square feet of building area per full-time personnel. B. Facility Planning and Adequacy Analysis The Imperial Police Station is a 3,788 SF Facility and houses the Police staff and support staff including a Records Clerk and a Clerk Typist and a ½ time office assistant. Patrol officers are out on the field during their shifts. The City of Imperial Police Department has a minimum of two police officers on duty per shift. Each shift is 12 hours in length. Dispatching services are contracted through the City of El Centro Police Department. 1. Inventory of Existing Facilities Existing facilities include police department personnel. The City of Imperial is served by seventeen (17) sworn officers: one (1) Police Chief, one (1) Captain, three (3) Sergeants, one (1) Corporal, one (1) Detective, eight (8) Patrol Officers and officer assignments for one (1) Motor Officer, one (1) Canine Officer, one (1) School Resource Officer. There is an additional Officer assigned to Street Interdiction Team. Two reserves and one volunteer are also a part of the department but not counted as a part of total personnel. According to an inventory provided by the Imperial Police Department, the department has the following existing policing and law enforcement personnel and facilities: Facilities  3,788 square feet of building  Ten (10) Patrol Vehicles  Six (6) Support Vehicles  One (1) Motorcycle 65 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION 2. Adequacy of Existing Facilities The existing police department facilities do not adequately serve the community. The current facility lacks a community room, an emergency operating center, restrooms for public usage, interview rooms, female locker room and restroom facility, adequate evidence rooms with proper ventilation, and adequate space for report writing. Additionally, there are only two holding cells. Sergeants currently share one office with no room for growth, and there is no secured parking for the Police Units and Officers’ private vehicles. Based on the performance standards, the existing demand for law enforcement facilities is as follows: Staff Level Existing Population x Performance Standard = Current Officer Demand 17,313 Population x 1.6 Officers / 1,000 population = 27 Sworn Officers. Existing Population x Performance Standard = Current Volunteer Demand 17,313 Population x 0.25 Volunteers / 1,000 population = 4 Volunteers Facility Full-Time Personnel x Performance Standard = Current Demand 27 full-time personnel x 237 Sq. Ft. of Building Area = 6,399 Sq. Ft. The Police Department currently has a staffing level of 17 officers and one volunteers thus a deficiency of -10 police officers and -3 volunteers. Based on the current demand for 6,399 square feet of building space, there is a current deficiency of -2,611 square feet given that the current offices are limited to 3,788 SF. 3. Future Demand for Facilities The City is estimated to have a population of 62,541 people by the year 2035, using planned development figures. Using the established performance standard, the City will need 100 sworn officers 50 patrol vehicles to meet future demand by the year 2035. Therefore, the City will need to employ 83 more sworn officers and obtain 40 more patrol vehicles by the year 2035. In order for the Police Department to meet the performance standard in the future, there will also be a need for a total of 15 non-paid reserve officers/volunteers and 23,700 square feet of building space by the year 2035. The City has set aside a 10-acre property on the northeast corner of Worthington Road and P Street for Public Facility usage as depicted in Exhibit 8-Existing and Proposed Police Protection Facilities. The future demand for law enforcement facilities is provided on the Demand for Police Protection Services. 66 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION Exhibit 8-Existing and Proposed Police Protection Facilities 67 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION It is assumed that the fire department will utilize approximately 10,000 square feet of the facility which leave 5,000 square feet for the Police Department. The public safety building is currently in the conceptual phase, so the size, number of people needed to adequately serve the station, and the cost is unknown at the time of preparation of this Service Area Plan update. Based the analysis conducted by this Service Area Plan, it does not appear that a joint use public safety facility at 15,000 square feet will be adequate for demand beyond 2020. The planned public safety facility would include training facilities to be shared by the fire and police departments. 4. Opportunities for Shared Facilities Although the City of Imperial maintains its own Police Department, it fully utilizes facility sharing opportunities. Dispatching services are currently provided through the 911 dispatching facility located in the City of El Centro. However, a regional dispatching facility that would be located within the City of Imperial is being considered. Additionally, the Imperial Police Department and the County Sheriff provide emergency law enforcement back-up for each other on an as needed basis. It is further anticipated that the Police Department will share a new facility with the Imperial County Fire Department on the aforementioned 10 acre property at the northeast corner of Worthington Road and P Street. 5. Phasing As the City’s population increases, adequate Police Department staff and patrol vehicles can be added, as necessary, in order to meet the current level of service standards. The following Table P-1 represents the demand for police department staff, vehicles and square footage for the next 20 years in 5 year increments. A more detailed service demand is noted on Table P-1 which includes reserves and other personnel. Table P-1 - Projected Police Service Demand Year Projected/Planned Police Service Demand Population 11,139 SF Facility 2020 29,476 47 Police Officers/24 Vehicles/7 Volunteers 18,249 SF Facility 2025 48,692 77 Police Officers/39 Vehicles/12 Volunteers 20,145 SF Facility 2030 53,533 85 Police Officers/43 Vehicles/13 Volunteers 23,700 SF Facility 2035 62,541 100 Police Officers/50 Vehicles/15 Volunteers 68 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION C. Mitigation Temporary buildings, vehicles and personnel can be added incrementally as demand for police protection service demand increases with population growth and until the permanent capital investments can be made. The following is a list of mitigation recommendations for Police Protection: P-1 The City of Imperial shall continue to monitor the response times for priority 911 calls to ensure adequate public safety. P-2 Prior to the year 2017, a financing mechanism shall be identified that will enable the City to construct a new police station with possible dispatching services. P-3 The Police Department shall continue obtaining grants and other funds to combat crime through proactive preventative measures. P-4 The City of Imperial and the Imperial Police Department should consider the preparation of a Law Enforcement Facilities Master Plan that conducts an in depth analysis of the facility needs to meet the goals and objectives of the Police Department through build out of the City of Imperial by 2020. D. Financing The current revenue sources for police protection services include property and sales taxes from the City’s general fund. The 2014-2015 budget allocated approximately $2,380,204 for police protection services from the City’s general fund. Other revenue is derived from special revenue sources including the State C.O.P.S. Grant (1584 COPS Grant), asset forfeitures, and Development Impact Fees. 1. Current and Per Capita Costs The 2014-2015 City of Imperial budget provided approximately $2,380,204 for police protection services from the City’s General Fund. Using the City’s current population of 17,313, police protection service costs $137.48 per resident. This cost was determined by dividing the funds appropriated from the general fund for police protection services by the existing population. A cost estimate for future police services is provided in Table P-2 below. $2,380,204 / 17,313 population = $137.48 per capita 69 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN POLICE PROTECTION Table P-2 Projected Police Service Costs Year Projected/Planned Police Service Cost Population 2020 29,476 $4,052,360.48 2025 48,692 $6,694,176.16 2030 53,533 $7,359,716.84 2035 62,541 $8,598,136.68 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources and continue to contract with the City of El Centro for dispatching services. However, due to the future growth anticipated, other funding sources for a new police station with possible dispatching facilities and additional vehicles and equipment will be needed. Further descriptions of these and other financing mechanisms are provided in the Financing section. 70 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LIBRARY V. LIBRARY The Imperial Public Library is owned and operated by the City of Imperial and it is located at 200 West 9th Street. The single library serves the entire population of Imperial. Services provided by the library include circulation of library materials to all patrons, reference service, audio visual services, computer use and other services. A. Performance Standard The performance standard for library facilities was determined during the preparation of the Service Area Plan approved by LAFCO on January 25, 2001. It was based on the existing library facilities square footage and the existing population at the time of the preparation of the Service Area Plan. Therefore, the performance standard for library facilities for the City of Imperial is 217 square feet of library facilities per 1,000 residents. B. Facility Planning and Adequacy Analysis This analysis provides an inventory of the existing library facility owned by the City of Imperial, the existing and future demand for facilities, as well as a projected phasing schedule. The purpose of this analysis is to determine if the existing facilities are adequate and to identify approximately when additional facilities will be needed in order to meet future demand. 1. Inventory of Existing Facilities As noted above, the City of Imperial operates and maintains its own public library. The library staff consists of two full-time personnel and four part-time employees. The library was in the process of hiring another part-time employee at the time this Service Area Plan was being prepared. The Imperial Public Library located at 200 West Ninth Street currently shares 7,260 square feet of space with the Council Chambers/Community Center, with an estimated 4,920 square feet strictly for library use (2,340 square feet is used for Council Chambers/Community Center). The library houses the following: Collection  31,692 books  391 serial volumes  536 audio materials  720 video items  1 database-1500+ eBooks an Audio eBooks  26 current serial subscriptions Computers and Equipment  1 copier for staff/public use  11 public use computers/1 library catalog computer 71 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LIBRARY  12 laptops and 1 storage/charging cart (for literacy programs)  3 library staff computers  2 black/white laser printers  1 fax machine for staff/public use  Video surveillance equipment (3 cameras, monitor/VCR)  Miscellaneous (shelving, paper back spinners, tables and chairs) 2. Adequacy of Existing Facilities Using the performance formula provided above of 217 SF per 1,000 residents, the existing demand for library facilities is 3,757 square feet. Based on the performance standard formula, there is a surplus of 1,163 square feet of library building square footage. Existing Population x Performance Standard = Current Facility Demand 17,313 Population x 217 Sq.Ft. / 1,000 population = 3,757 Sq. Ft. The current space reserved for library use at the facility, of 4,920 SF of library space, is currently adequate and is currently undergoing another expansion. The current improvements at the library are estimated at $610,000 that will result in an additional 4,738 SF of total space, of which 2,754 will be reserved for library use. The ending library space by the end of 2015 will be 7,674 SF. As the population increases, there will be a need for additional library facilities, beyond the 7,674, by the year 2035. 3. Future Demand for Facilities As the City of Imperial continues to grow, so does the need for library facilities. With a planned population expected to reach 62,541 by the year 2035, additional library facilities will be needed to serve the future residents. In order to meet this future demand, an additional 5,897 square feet of library facilities, beyond the 2,754 SF library space expansion, will be needed by 2035. 4. Opportunities for Shared Facilities The City of Imperial participates in the SERRA Cooperative System that includes libraries from Imperial County and San Diego County for inter-library loan program, the library shares resources with other libraries in the region. The public library will continue to pursue this opportunity for shared resources in order to keep costs down while providing acceptable services to City residents. The library further has a conference room that is used for closed sessions by City Council. If needed, the library could be used for public meetings when other City administrative facilities are occupied. 72 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LIBRARY 5. Phasing The yearly demand for library facilities is shown on Demand for Library Services table below. The yearly demand Table L-1 below provides the square footage needs for the library over a twenty-year period in five-year increments. Table L-1 Projected Library Service Demand Year Projected/Planned Library Service Demand Population 2020 29,476 6,396 SF Facility 2025 48,692 10,566 SF Facility 2030 53,533 11,616 SF Facility 2035 62,541 13,571 SF Facility C. Mitigation The City shall support the continuation of library services as a necessary and desirable community service facility. The following mitigation is recommended: L-1 The City of Imperial shall continue efforts to obtain additional funding in order to continue providing adequate library services to the residents. D. Financing The current revenue sources for library facilities and services include property and sales taxes from the City’s general fund and impact fees. The 2014-2015 budget allocated approximately $210,751 for library services from the City’s general fund. 1. Per Capita Costs The 2014-2015 City of Imperial budget identifies approximately $210,751 for continued operation of library services. Using the City’s current population of 17,313 library services cost $12.17 per resident. This cost was determined by dividing the funds appropriated form the general fund for library services by the existing population. A cost estimate for future library services is provided in the Table L-2 below. Note that the table uses 2015 dollars, and based on the following: $210,751 / 17,313 population = $12.17 per capita 73 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN LIBRARY Table L-2 - Projected Library Service Costs Year Projected/Planned Library Service Cost Population 2020 29,476 $358,722.92 2025 48,692 $592,581.64 2030 53,533 $651,496.61 2035 62,541 $761,123.97 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources for the continued maintenance and operation of the Imperial Public Library. Due to future growth anticipated, other funding sources should be considered to maintain an adequate level of library service for the existing and future residents. There are several funding sources for library facilities such as community facilities district, special assessment district, the California Literacy Campaign Fund, as well as Community Development Block Grants and user fees. Further descriptions of these and other financing mechanisms are presented in the Financing Plan of this Service Area Plan. 74 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN RECREATIONAL AND PARK FACILITIES VI. RECREATIONAL AND PARK FACILITIES There are a number of recreational facilities within the City of Imperial including open space areas used for recreation. Open space and recreational uses include fourteen city parks. City parks offer picnic facilities and recreational opportunities, including baseball and softball diamonds, basketball courts and tot-lots. Eager Park is centrally located in the City and also has a splash pad. In addition to these amenities, the City also offers an array of local recreation programs and services for children, adults, and seniors at City facilities. A. Performance Standard The City of Imperial has adopted the Performance Standard of 3.0 acres parkland/1,000 population. This standard is applied to developer impacts and further stipulated as a Goal in the Open Space and Recreation Element of the General Plan. B. Facility Planning And Adequacy Analysis The existing public parks within the City of Imperial are owned and operated by the City of Imperial Parks Department. The recreation department has six (6) full time employees (three maintenance employees and three professional employees) and one part time employee. Part-time employees are increased to 25 during the summer months. 1. Inventory of Existing Facilities The City of Imperial currently has over 50 acres of parkland as depicted in Exhibit 9- Park Facilitie7 s. Park inventory included over 50 acres as follows: Table R-1 City of Imperial Park Space Park Acres C.A.

Adequacy of Existing Facilities Using the goal of 3.0 acres per 1,000 population, there should be a minimum of 51.94 acres of parkland. Based on the existing park acreage of 52.25 acres, there is an existing surplus of 10.62 acres. The adequacy is calculated as follows: Existing Population x Performance Standard = Current Demand 17, 313 Population x 3.0 Acres / 1,000 population = 51.94 Acres Existing Facilities – Current Demand = Adequacy 62.87 Acres – 51.94 Acres = 10.93 Acres Surplus The city currently has a surplus of park acreage. It is important that adequate park facilities be provided to serve the residents of Imperial. The City actively requires the development community to provide parkland either through the payment of the development impact fee or through parkland donations or improvements as a part of the development approval process. 3. Future Demand for Facilities Based on a 2035 population projection of 62,541 the City of Imperial will need 187.62 acres of recreational open space in order to be consistent with the performance standard objective of the General Plan. This indicates that the City will need to obtain an additional 135.37 acres of recreational open space by the year 2035. This figure was determined as follows: 3.0 Acres / 1,000 Population x 62,541 population = 187.62 Acres of Future Demand 187.62 Acres of Future Demand - 62.87 Acres Existing Parkland = 124.75 Acres Needed The City has been planning a Regional Park and Equestrian Center to be located along the northern part of the City Limits in an area bound by Larsen Road to the north, Ralph Road to the south and Nance and La Brucherie Roads at the respective west and east boundaries. The subject area encompasses 144 acres of which some will be dedicated for recreational facilities. 4. Opportunities for Shared Facilities The City currently contracts with the Imperial High School during the summer for use of the pool located at the high school for public swimming. The City has Joint Use Agreements with the Imperial Unified School District for use of other recreational facilities outside of school hours. There are three schools within Imperial Unified School District that could provide for recreational opportunities 77 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN RECREATIONAL AND PARK FACILITIES during the after school hours and on weekends. A Joint Use Agreement with the Imperial Unified School District for the new Frank Wright Middle School at the corner of Fifteenth Street and Imperial Avenue was adopted by the City and the School District. The Ben Hulse gym is also used for dance and drama. Additional discussions may occur between the School District and the City regarding additional joint use agreements for use of school facilities for recreation purposes. 5. Phasing Based on the 3.0 acres per 1,000 population performance standard for parkland, the following Table R-2 represents the demand for recreational land/parkland acreage for the next 20 years in five year increments. Table R-2 Projected Parkland Demand Year Projected/Planned Parkland Demand Population 2020 29,476 88.43 Acres 2025 48,692 146.08 Acres 2030 53,533 160.60 Acres 2035 62,541 187.62 Acres C. Mitigation The City of Imperial should continue to pursue various means by which to obtain and provide for adequate park facilities for the existing and future residents of the City of Imperial. The following are mitigation recommendations to achieve adequacy for park facilities. R-1 Continue to require developers of new subdivisions to dedicate parkland and/or pay the development impact fee to ensure that future residents pay their fair share for impacts on park facilities. R-2 Pursue federal and state grants and aid funds to ensure there are sufficient parks in the future. D. Financing The current revenue sources used to pay for park facilities include property and sales taxes from the general fund, user fees for recreational activities and pool use, and park impact fees collected from new residential developments. The City of 78 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN RECREATIONAL AND PARK FACILITIES Imperial will continue to use these funding sources for the continued maintenance and operation of parks and recreational facilities. 1. Per Capita Costs The 2014-2015 City of Imperial budget provided approximately $617,592 for parks and recreation. Using the City’s current population of 17,313, parks and recreation facilities cost $35.67 per resident. This cost was determined by dividing the funds appropriated for parks and recreation facilities by the existing population. The Projected Recreation Cost Table R-3 provides a cost for park operation and maintenance based on the year 2015 dollars and in 5- Year increments. $617,592 / 17,313 population = $35.67 capita Table R-3 Projected Recreation Cost Year Projected Population Recreation Cost 2020 29,476 $1,051,408.92 2025 48,692 $1,736,843.64 2030 53,533 $1,909,522.11 2035 62,541 $2,230,837.47 2. Future Funding Sources The City of Imperial will continue to use the existing funding sources for the continued maintenance and operation of the park and recreation facilities. However, due to the anticipated future growth, other funding sources will be needed in order to develop the regional park and equestrian center in order to provide an adequate level of service for future residents. There are several other funding sources available for park facilities such as community facilities district, special assessment district, as well as Community Development Block Grants and other state and federal grants. Further descriptions of these and other financing mechanisms are provided in the Financing Plan section. 79 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION VII. CIRCULATION & TRANSPORTATION A. Performance Standard The Circulation Element of the Imperial General Plan was created to sustain safe and efficient vehicular travel throughout the City. The Circulation Element is consistent with the Land Use Element which dictates that no land use will be approved that will increase the traffic on planned or existing City streets above the street’s existing design capacity at a “level of service” of “C” or above. This “level of service” criterion is the most traditional method used to determine the current and future needs for adequate circulation facilities with an assignment of A to F as noted below. Level of Service Roadway Performance Standard Represents free flow. Individual drivers have a high degree of LOS “A” freedom to select their travel speeds and are unaffected by other vehicles. Represents stable flow, but individual drivers are somewhat LOS “B” affected by other vehicles in determining travel speeds. Represents stable flow, but the selection of the speeds of LOS “C” individual drivers is significantly affected by other drivers. Represents a condition of high density, stable traffic flow in which LOS “D” speed and freedom of movement are severely restricted by the presence of other vehicles. Represents operating conditions at or near capacity. Individual vehicles have little free to maneuver within the traffic stream and LOS “E” any minor disruptions can cause a breakdown in the flow of traffic. Represents breakdown conditions. At this level of service, LOS “F” speeds are low, delays are high, and there are more vehicles entering the roadway than can be accommodated. The City of Imperial, similar to many other jurisdictions, has started using a different performance standard known as Complete Streets. Complete Streets is a transportation policy and design approach that requires streets to be planned, designed, operated, and maintained to enable safe, convenient, and comfortable travel and access for users of all ages and abilities regardless of their mode of transportation. Modes of transportation in the City of Imperial include pedestrians, bicycles, cars, trucks, buses, trains and emergency vehicles. 80 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION B. Facility Planning and Adequacy Analysis The City of Imperial contains a circulation system which is predominantly oriented in a north/south and east/west grid system. The major north/south arterial system consists of Austin Road, Imperial Avenue, State Highway 86, P Street (Clark Road), and Dogwood Road. The major east/west arterial system consists of Ralph Road, Neckel Road, Fifteenth Street, Barioni Boulevard (Worthington Road) and Aten Road. These streets have independent classifications in accordance with the Imperial General Plan and updated structural section guidelines as follows: Table C-1 City of Imperial Major Street Classifications & Guidelines CLASSIFICATION ROW/PAVED WIDTH NO. OF LANES Highway 300/226 Feet 4 Major Arterial 102/80 Feet 4 Secondary Arterial 84/50 Feet 2 Industrial Collector 70/44 Feet 2 Residential Collector 60/40 Feet 2 1. Inventory of Existing Facilities- The City of Imperial maintains over seventy one (71) lineal miles of roadway (Source: ICTC, 2015). The existing facilities, identified per the noted classifications are depicted in attached Exhibit-10 City of Imperial Circulation System. A more detailed discussion for each of the facilities identified is noted below: Signalized Intersections - The City of Imperial contains six signalized intersections which include the intersections of Aten Road/Highway 86, Barioni Boulevard/Highway 86, Fifteenth Street/Highway 86, La Brucherie/Aten Road, Clark Road/Aten Road and Cross Road/Aten Road. A seventh signal is planned for the Aten and Dogwood intersection. State Highway – Highways are main roads that typically connect major towns or cities and are designed for high speed traffic. Highways collect a large volume of traffic with speed limits from 55 to 70 miles per hour. The City of Imperial has approximately 3.5 lineal miles of highway within its incorporated City Limits.  State Highway 86 - Highway 86, a major four lane Expressway, is located within the City of Imperial but is maintained and managed by the California State Department of Transportation. The State Department of Transportation also controls the State Highway right-of-way. 81 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION Major Arterials - Major arterials move traffic through a City from one point to another. Speed limits on major arterials are typically 45 mph and are designed with four lanes. On-street parking should be limited and residential lots should not have direct access onto major arterials. The City of Imperial has over eight (8) lineal miles of existing and planned major arterials within its current incorporated City Limits.  Ralph Road-The majority of Ralph Road that lies within the City’s Sphere of Influence is currently within unincorporated areas of Imperial County and has a pavement width less than the designed pavement width/capacity of a major arterial.  Neckel Road- The majority of Neckel Road that lies within the City’s Sphere of Influence is currently within unincorporated areas of Imperial County and has a pavement width less than the designed pavement width/capacity of a major arterial.  Barioni Boulevard (Worthington Road)- The majority of this major arterial, within the Sphere of Influence boundaries, is within the incorporated City Limits as Barioni Boulevard, but not improved as a four lane roadway. Roadway sections within unincorporated areas of Imperial County have a pavement width less than the designed capacity of a major arterial.  Aten Road- All of Aten Road within the City’s Sphere of Influence is within the Imperial City Limit boundary. The entire roadway segment between Austin Road and Dogwood Road are improved with four lanes and to the full pavement width.  La Brucherie Road (Between Barioni Boulevard & Larsen Road)- Although La Brucherie Road is designated as a major arterial, between Larsen Road at the north and Barioni Boulevard to the south, it is not improved to designed capacity, and is an unimproved facility north of Larsen Road.  P Street (Clark Road)- There are many segments of P Street that are still within unincorporated areas of Imperial County. P Street is currently not improved to its designed capacity.  Dogwood Road- The majority of Dogwood Road within the Sphere of Influence is within unincorporated areas of Imperial County. Dogwood is a major arterial that links to several Imperial County communities and is further planned as a transit corridor. The roadway segment within Imperial’s Sphere of Influence is not improved to its designed capacity. 82 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION Exhibit-10 City of Imperial Circulation & Transportation System 83 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION Secondary Arterials - Secondary arterials move traffic in a similar manner as major arterials, except they are designed with two lanes instead of four lanes. These arterials carry a lower volume of traffic and typically have a 35 mph speed limit. On-street parking should be limited and residential lots should not have direct access onto secondary arterials. The City of Imperial has just over seven (7) lineal miles of existing and planned secondary arterials within the current City Limits. Secondary Arterials Improved at Designed Capacity: • Imperial Avenue • Fifteenth Street Secondary Arterials Not Improved to Designed Capacity: • Cross Road • Second Street • Treshill Road • P Street • Huston Road • Brewer Road Industrial Collectors - Industrial collectors have a wider curb to curb width in order to facilitate large truck movements. These collectors are designed for low volumes with speed limits 30 to 35 miles per hour. The City of Imperial has over just over three (3) lineal miles of existing and planned industrial collectors within the current incorporated City Limits. Industrial Collectors Improved at Designed Capacity: • La Brucherie Road (Aten Road to Airport) Industrial Collectors Not Improved to Designed Capacity: • First Street (east) • Fourth Street (N Street to P Street) • M Street • N Street Residential Collectors - Local collectors collect a smaller volume of traffic from a smaller area. Streets are usually two lanes wide with a speed limit of 25 to 30 miles per hour. Access is not restricted and on street parking is available. The City of Imperial has over fifty (50) lineal miles of existing and planned residential collectors within the incorporated City Limits. Residential Collectors  La Brucherie Road (South City Limits to Aten Road)  First Street (west)  Third Street  Fourth Street (B Street to M Street)  Remaining number and letter streets not previously mentioned. 84 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION Signalized Intersections-The City of Imperial contains five signalized intersections which include the intersections of Aten Road/Highway 86, Barioni Boulevard/Highway 86, 15th Street/Highway 86, La Brucherie/Aten Road, and Clark Road/Aten Road. A sixth signal light is currently under construction for the Aten Road/Dogwood road intersection. Transit Services and Facilities-There are five IV Transit bus routes serving the City of Imperial. Barioni Boulevard, SR-86 and Aten Road are recommended as transit priority routes. There a total of three bus stops equipped with bus shelter facilities within the City Limits as noted below. A fourth bus stop is at Imperial Valley College within a future planned Sphere of Influence.  Imperial Avenue just North of Barioni Boulevard along East  East Barioni Boulevard just East of North K Street  West Aten Road just East of La Brucherie Road 2. Adequacy of Existing Facilities Although all the existing streets are not constructed to full build-out and some are not constructed to designed capacity, as noted in existing conditions, they are operating at adequate volume to capacity ratios of 0.80 or better. There have been a number of traffic studies tied to planned development that conclude existing conditions are satisfactory and that it is only when new development is in place modifications and improvements would be needed. The existing circulation system is adequate to accommodate the current needs of the City. Existing roadways properly link existing land uses. In the proceeding section, this Service Area Plan discusses proposed improvements to accommodate anticipated development within the City Limits and in unincorporated areas planned for annexation. 3. Future Demand of Facilities As the City of Imperial continues to grow, future improvements will be required to build streets to full improvements in accordance with the design standards set forth by the City of Imperial Engineering Department and with a Complete Street focus. Future roadway improvements should be designed to provide a circulation network that prioritizes and provides safe and convenient, and attractive facilities for all users of the system. Roadway segments in incorporated areas that are planned for major improvements within the Service Area planning period are noted in Table C-2 for connectivity. 85 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION Table C-2 Future Roadway Improvements in City Limits Street Name Street Street Improvement Length Type Segment Major Cross Road to Aten Arterial Dogwood Road Full Street 5,250 LF Major Barioni Blvd to La Brucherie Half Street 9,900 LF Arterial Larsen Road Major P Street to Worthington Half Street 4,500 LF Arterial 4,500 LF East Major Aten Road to Dogwood Half Street 2,690 LF Arterial Treshill Road Major Highway 86 to Ralph Full Street 4,930 LF Arterial Nance Road Major Aten Road to Clark Street Half Street 2,690 LF Arterial Treshill Secondary 1st Street to P Street Arterial 12th Street Half Street 4,200 LF Secondary Highway 86 to Neckel Arterial Rodeo Drive Full Street 300 LF Secondary Rodeo Drive to Neckel Half Street 1,400 LF Arterial 1,400 LF East Residential La Brucherie to 15th Street Collector E Street Half Street 1,220 LF Residential Nance Road to Brewer Collector La Brucherie Half Street 2,460 LF Residential Wall Road to Shiloh Collector Aten Road Full Street 2,020 LF Residential Joshua Tree to La Brucherie Collector Treshill Full Street 2,820 LF Source: City of Imperial Planning Department Developers will construct required internal street improvements associated with each project Additionally, developers will be required to construct frontage improvements along all Circulation Element roadways adjacent to each proposed annexation and future project. Bikeways may be necessary along Major Arterials such as Aten Road. Another City focus is to provide for separated multi-use paths for bikeways, pedestrian walkways, or equestrian facilities along major collector roadways which prioritize vehicular use. Some key locations considered for separated facilities include: 1) Along Austin Road (to include equestrian pathway/connection) 2) Along Highway 86 (for pedestrian safety to serve higher density areas) 3) Along Aten Road (to connect bicyclists with Imperial Valley College) The City’s current facility demand continues to be highly automobile-oriented.

Opportunities for Shared Facilities While there are no real opportunities for shared roadway facilities with an adjacent jurisdiction, the City’s system links with City of El Centro roadways, to the State and with the County and State Highway system. The City continues to work with local and State government agencies to monitor the operation of the regional system for implementation of necessary improvements. 5. Phasing Roadway improvements identified within City Limits are anticipated to be completed within a five year timeframe. Improvements to circulation facilities within annexation areas will be provided concurrently with new development as noted in Table C-4. Each five year section identifies the total lineal fee of roadway as well as the anticipated new mileage to be maintained by the City of Imperial after annexation and improvement. By the end of the 20 year planning period an additional 22.5 miles of new arterial and major collector roadways constructed by developers are anticipated to be maintained by the City. Developers are further responsible to pay all associated fair share costs of traffic signals serving the development.

C. Mitigation Most of the circulation improvements identified will be constructed by the future developers as development occurs. The following are the recommended mitigation measures: C-1 For Industrial and Residential Collectors, the developer shall be responsible for two street improvements including one travel lane, curb, gutter, and sidewalk constructed to City standards for all land fronting on said collectors. C-2 For Major and Secondary Arterials, the developer shall be responsible for frontage improvements including two medians, one travel lane, curb, gutter, and sidewalk. C-3 New development that results in increased traffic impacts that exceed 5,000 vehicles per day on local streets shall provide for a traffic study to outline needed improvements to mitigate the increased traffic levels. 89 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION D. Financing The existing funding sources for circulation improvements, maintenance and operation come from the City’s general fund, Motor Vehicle In-Lieu Tax, State Gas Tax, CalTrans, and LTA Measure D as well as developers. The City of Imperial will continue to utilize these funding sources. 1. Current Costs and Per Capita Costs for Operation & Maintenance The current cost for the continued maintenance and operation of the circulation system in the City of Imperial is approximately $17.72 per capita. The 2014 - 2015 City of Imperial budget allocated $306,817 for Streets & Sidewalk maintenance which is primarily used to match available transportation grant funds. Using the City’s current population of 17,313 residents, maintenance and operation of the circulation maintenance cost approximately $17.72 per capita as calculated below and projected in Table C-5. $306,817 /17,313 population = $17.72 per capita Table C-5 Projected Street Maintenance Costs Year Projected Population Street Maintenance Cost 2020 29,476 $522,366.89 2025 48,692 $862,908.41 2030 53,533 $948,699.50 2035 62,541 $1,108,226.52 2. Current Estimated Costs for Capital Improvements Development Impact Fees are levied by the City of Imperial for circulation facilities.

Future Funding Sources Objective 8 of the General Plan Circulation Element states “the financing of improvements to the City circulation system made necessary by new development projects shall be borne by the developer, while the maintenance and improvements of the existing street system shall be borne by the City and its residents.” The City of Imperial collects development impact fees as a means to assist in the funding of future capital improvements to circulation facilities. Both future residential and nonresidential developments will be required to pay development impact fees. Policy 8 of the Circulation Element suggests that the City utilize assessment district financing, grants and other sources of revenue as well as a five-year capital improvement plan to help finance City circulation improvements. There are several funding sources for circulation facilities 93 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN CIRCULATION AND TRANSPORTATION such as community facilities district, special assessment district, Certificate of Participation, Safe, Accountable, Flexible, and Efficient Transportation Equity Act (SAFETEA), Surface Transportation Program (STP), as well as Community Development Block Grants and other state and federal grants. Further descriptions of these and other financing mechanisms are provided in the Financing section. 94 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER VIII. SANITARY SEWER The City of Imperial owns, operates, and maintains a wastewater collection and treatment system that services to the City of Imperial, and some isolated areas immediately outside of the City boundary, but within the Sphere of Influence. The Imperial Water Pollution Control Plant (IWPCP) is located at 701 East 14th Street, located just east of the railroad tracks. The existing wastewater treatment plant is currently located on a 4.68 acre site (net acreage) and services the entire City limits. The IWPCP was constructed in the 1940’s and was rebuilt in 1995. The most recent expansion was completed in 2004, and has a current treatment capacity of 2.4 million gallons per day (MGD). Much of the information for this section was acquired from the Master Plan for the Sanitary Sewer Collection System for the City of Imperial prepared by BJ Engineering and Surveying, Inc., and dated June 2008. Some of the information provided in this section is paraphrased while other parts are used word-for-word from the Master Plan. Additional information was provided by the City of Imperial Public Works Department. For additional details relating to wastewater treatment and conveyance, the Master Plan should be consulted. A. Performance Standard Although there are no adopted Performance Standards for wastewater treatment and conveyance, there are design criteria and regulations that must be met to ensure that adequate wastewater treatment and conveyance is provided. The Performance standards and requirements for the Imperial Wastewater Treatment Plant are further governed by the National Pollution Discharge Elimination System (NPDES) discharge permit number CA0104400 adopted by the California Regional Water Quality Control Board, Colorado River Basin Region on September 16, 2010, by Board Order Number R7-2010-0020. The NPDES permit expires on September 30, 2015, and was being renewed as of the date of this Service Area Plan. The NPDES permit establishes the Waste Discharge Requirements for the wastewater treatment plant. The NPDES permit establishes the rated capacity of the wastewater plant, discharge prohibitions, effluent limitations and discharge specifications, receiving water limitations, standard provisions for the operation of the wastewater treatment plant, monitoring and reporting program requirements, compliance requirements, and special provisions. The NPDES discharge permit also establishes minimum standards and criteria by which the IWPCP operates. At a local level, the City further has established design criteria for the collection and conveyance system. Design capacity of a pipeline is the general calculated capacity of the pipeline using the Manning formula. For system analysis, peak dry weather flow (PDWF) does not exceed 75 percent of the design capacity of the pipeline. Accordingly, 25 percent of the pipeline capacity is reserved to accommodate peak wet weather flow 95 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER (PWWF) incurred during wet weather conditions. The 25 percent reserve is therefore provided to account for groundwater infiltration and rainfall dependent inflow, plus additional sewer capacity reserve allowance. This 25 percent reserve contingency factor is a commonly used allowance in evaluating wastewater utilities. The following are the design criteria for determining pipeline capacity: Table S-1 Pipeline Design Criteria Pipe Diameter Design Criteria 8” to 10” ½ Full @ Peak Flow 12” to 18” ⅔ Full @ Peak Flow 21” or greater ¾ Full @ Peak Flow Gravity pipelines should also have a general peak flow velocity of 2.0 fps (feet per second) at PWWF to ensure adequate flow. Pipelines that cannot reach this minimum flow velocity should be assisted with pump stations. Pump station adequacy is based on two criteria: 1) the ability of the pump station to pump the PWWF and 2) wet well adequacy for pump cycling. B. Facility Planning and Adequacy Analysis As previously noted, the 2.4 MGD wastewater treatment plant for the City of Imperial is located in the northwest portion of the City within two parcels of land. The major treatment units are located north of Fourteenth Street and east of the Southern Pacific Railroad Right-of-Way on the 4.68 acre site. The City also owns a 15-acre site, located northeast of the above-mentioned site, which is occupied by treatment ponds for emergency use. Over the last few years, the average daily flow to the City of Imperial Wastewater Treatment Plant has varied, with monthly averages ranging from 1.4 million gallons per day (MGD) to 1.6 MGD during the 2014 calendar year. 1. Inventory of Existing Facilities Wastewater Treatment Plant- The existing wastewater treatment plant uses primarily an oxidation ditch-type process. The process flow scheme consists of a headworks structure, an effluent pumping station, a grit chamber, an oxidation ditch, an intermediate pump station, three secondary clarifiers, an ultra-violet light disinfection chamber, an 18-inch diameter outfall line, an aerobic digester, and 10 sludge drying beds. Exhibit 11- Wastewater Facilities identifies the location of the Imperial Water Pollution Control Plant, the primary conveyance system and pump stations 96 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER Exhibit 11- Wastewater Facilities 97 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER Wastewater Conveyance System- The topography of the City is fairly flat, sloping gently to the northeast thus gravity flow is optimized. The existing wastewater collection system consists of vitrified clay pipe (VCP) and polyvinyl chloride (PVC) pipelines, and includes approximately 63 miles of gravity sewers ranging in size from 6 to 24 inches in diameter, 16 lift stations, and 6 miles of force mains. Trunk sewers in the major roads transport wastewater to the treatment plant. Wastewater Pumping Stations- As previously noted, the topography of the City is fairly flat, thus pumping stations are necessary in order to receive flows and pump them through force-mains located throughout the incorporated City limits. Table S-2 details the sixteen pumping stations noted in Exhibit 12 and available throughout the City.

Adequacy of Existing Facilities Wastewater Treatment Plant- The wastewater treatment facility has performed adequately because of its inherently conservative design and the fact that the existing flows (ranging between 1.4 MGD and 1.6 MGD) are less than the design flow of 2.4 million gallons per day (MGD). Even with current planned development, the flow would not increase to designed capacity until 2020. The current wastewater treatment plant is undergoing a $3 Million capital improvement project. The improvements consist of improvements to the headworks screening and some internal pipeline reorganization. Conveyance System- BJ Engineering and Surveying Inc., developed a computer model of the existing City wastewater system using data which was available for existing facilities and established flow estimates. Using this model, the hydraulic capacity of the existing system was evaluated under peak wet weather flow (PWWF) conditions in 2005. The results of the modeling indicated that the existing system provides adequate capacity at average daily flow (ADF) conditions, but during PWWF conditions, two pipelines did not have adequate capacity. These pipelines are Pipes #14 and #17 and are located along N Street between Barioni Boulevard and 12th Street. The flow into these lines is currently being rerouted and capacity will be satisfactory upon project completion. The model also confirmed that the capacity remaining in the Barioni Boulevard trunk sewer is required to serve future development in its dedicated service area. The existing trunk sewer system is therefore not available to serve future development areas outside of the present service area. The capacity of the trunk line from B Street to N Street and from Barioni Boulevard to 14th Street needs to be evaluated. It is estimated that 85% of this pipe section is clay and has deteriorated over time which has resulted in reduced capacity. A similar situation is occurring with the sewer trunk line in 13 th Street from C Street to N Street. Wastewater Pumping Stations- Pump stations are constructed as development occurs, thus many of the existing pump stations are aging. Pump Station #16 is the newest, serving the Victoria Ranch Subdivision. Pump Station #16 is expected to be placed into operation by the end of 2015. There are at least three older pump stations that need improvements. Improvement priority is needed for pump stations #1, #4 and #6 as they do not adequately meet the current demand. Table S-3 Pump Station Adequacy details the current condition of all the pump station facilities and further identifies the areas they serve. 99 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER Table S-3 Pump Station Adequacy Pump Area/Development Serviced by 2015 Condition Station Station Sub-area VIII-Southern end, bound by HWY Needs Upgrade: PS-1 86 on east, City limit on south, Myrtle Avenue From 150 GPM to 400 GPM on the west and Aten Road on the north Residential Area bound by Dahlia Park, Ben Adequate PS-2 Hulse Elementary, and City Water Plant Residential Area bound by Sunset Ranch Adequate PS-3 Subdivision Residential Area bound by Sandalwood Glen Adequate PS-4 Subdivision and Wildflower North Subdivision Industrial Area between Industrial and West of Adequate PS-5 La Brucherie Residential Area bound by Sandalwood Glen Adequate PS-6 Subdivision and Wildflower North Subdivision Paseo Del Sol Subdivision and Border Patrol Needs Upgrade: PS-7 Station From 250 GPM to 500 GPM Portion of South Colonia Adequate PS-8 Wildflower North Subdivision and La Fuente Adequate PS-9 Patio Homes Victoria Ranch Subdivision Adequate PS-10 Imperial Business Park Subdivision Adequate PS-11 Monterrey Park Subdivision Adequate PS-12 Bratton Subdivision Adequate PS-13 Sky Ranch Subdivision Adequate PS-14 Mayfield Ranch Subdivision Adequate PS-15 Victoria Ranch Subdivsion Pending Activation (2015) PS-16 Source: 2008 Master Plan for Sanitary Sewer Collection System & 2015 Interview with Public Works Director. 3. Future Demand for Facilities Assuming a conservative impact of 100 GPD (gallons per day) per capita on the wastewater treatment facilities, the City projected Average Daily Flow wastewater flow demand is as follows: Table S-4 Daily Sewer Flow Projections 113FF Year Projected Population Average Daily Flow 2020 29,476 2.497 MGD 2025 48,692 4.869 MGD 2030 53,533 5.353 MGD 2035 62,541 6.254 MGD Demand is based on an assumed impact of 100 gallons per day per capita. 100 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER As previously noted, the City of Imperial average household size is 3.35 persons per household. The average discharge of wastewater is 100 gallons per day per person, thus each dwelling units discharges an average of 335 gallons per day. Assuming an impact of 335 GPD (gallons per day) per Equivalent Dwelling Unit (EDU) on the wastewater treatment facilities, the City was able to project non- residential impacts to water facilities from commercial and industrial operations. The projected average daily wastewater flow demand for all “units,” including non- residential equivalent dwelling units, is as follows: Table S-5 Daily Sewer Flow Projections with EDU’s 113FF Planned Total Planned Total Cumulative Non- Cumulative Equivalent Average Daily Flow Year Residential Development Dwelling Demand Equivalent Dwelling Units Units Dwelling Units 2020 8,799 12,170 20,969 7.025 MGD 2025 14,535 16,936 31,471 10.542 MGD 2030 15,980 16,997 32,977 11.047 MGD 2035 18,669 17,057 35,726 11.968 MGD Average Daily Flow is based on an assumed impact of 335 gallons per EDU 4. Opportunities for Shared Facilities The City of Imperial has plans to relocate the treatment facilities out to the Mesquite Lake area and build a regional Keystone Reclamation Plant to serve a number of unincorporated commercial/industrial operations, the Imperial Valley College and all of the City’s anticipated growth areas. The proposed wastewater treatment facility is to be located near the Keystone/Mesquite Specific Plan Area north of the City of Imperial in the jurisdiction of the County of Imperial and it will be a shared facility. The City and the County are currently working together to plan, construct and operate the treatment facility. The design plans, specifications, and bid documents shall include all information necessary to construct a fully functional 3.0 MGD average day capacity tertiary facility in conformance with the operational intent described in the approved PDR. The design shall be prepared to accommodate future plant expansions up to 10.0 MGD average day capacity. The design of the facility shall further conform to current City of Imperial Standards, County of Imperial Standards, current UBC requirements, AWWA requirements, and the “Greenbook” Standard Specifications for Public Works Construction (current edition). If there are conflicting standards, the City of Imperial Standard Drawings and Specification shall prevail. 101 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER 5. Phasing Improvement phasing is recommended at five year increments for budgetary purposes. Based on the results of the analysis performed by BJ Engineering, the following backbone improvements are recommended in order to provide adequate capacity during PWWF conditions: Short Term Improvements  Remove and replace the existing 8" pipeline along Highway 86- Imperial Avenue between Pumping Station #1 and Barioni Boulevard (from MH #160 to MH #10) due to age and condition considerations.  Install 8" force main north along La Brucherie Road from Pumping Station #10 to 15th Street. 5-10 Year Improvements  Remove and replace the existing 8" to 10" pipeline along Aten Road between Shilo Road and Highway 86 (from MH #362 to MH #166) due to age and condition considerations.  Install 12" gravity line east along 15th Street from 8" force main at La Brucherie Road to Pumping Station #11. 10-15 Year Improvements  Slipline the existing 8" to 12" pipeline along 13th Street between C and N Street (from MH #139 to MH #85A) due to age and condition considerations.  Install Pumping Station #13 along Aten Road near Dogwood Road to be able to serve Imperial Valley College  Construction of a new wastewater treatment facility - Keystone Reclamation Plant with an initial average day treatment capacity of at least 3.0 MGD to be expandable to 10 MGD. The facility shall be constructed to provide tertiary treatment and meet all applicable Title 22 requirements for recycled water reuse. 20 Year Improvements  Provide improvements to the Keystone Reclamation Plant Wastewater Treatment facility to expand capacity to meet projected growth. C. Mitigation The City of Imperial should continue to pursue various means by which to obtain funding and provide for adequate wastewater conveyance facilities for the existing and future residents of the City of Imperial. The following are 102 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER recommendations to maintain adequacy for wastewater treatment and conveyance facilities: S-1 Facilities identified in the Wastewater Master Plan update shall be constructed as new development and annexation of land occurs. S-2 Prior to the recordation of a final map within any of the annexation areas, a development agreement must be in place to ensure that adequate wastewater facilities will be provided during the PWWF conditions for the wastewater conveyance system being utilized by said annexation area. S-3 All system improvements shall be designed and constructed in accordance with Federal, State and local regulations. S-4 Construct new wastewater treatment facility at Mesquite Lakes. D. Financing The primary sources of revenue for wastewater treatment and conveyance facilities are the sewer service charges and sewer capacity fees. The sewer service charges function to subsidize off-site facilities such as sewer interceptors and sewer treatment plant operation and maintenance. The sewer capacity fee is based on the equivalent dwelling unit (EDU) impact created and funds planned expansions of the City of Imperial Wastewater Treatment Plant. The City will continue to utilize these funding sources in addition to searching for other sources to improve the existing system in order to meet future demand. 1. Current Costs and Per Capita Costs The current annual cost for the continued maintenance and operation of the sewer system in the City of Imperial is approximately $197.28 per capita. The 2014-2015 City of Imperial budgeted $3,415,567 for wastewater operations and debt service. Using the City’s current population of 17,313 residents, maintenance and operation of the wastewater facilities cost approximately $197.28 per resident per year. $3,415,567 / 17,313 population = $197.28 per capita Using the City’s current population, the per capita cost of $197.28 for the continued maintenance and operation of the sewer facilities are noted below in Table S-6 in five year increments. 103 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN SANITARY SEWER Table S-6 Projected Sewer Costs Year Projected/Planned Sewer Costs Population 2020 29,476 $5,815,124.64 2025 48,692 $9,606,121.89 2030 53,533 $10,561,170.69 2035 62,541 $12,338,088.48 Future cost estimates are based on current cost per capita for wastewater operations and debt service. These costs do not yet reflect the improvements and financing of the wastewater treatment facility to be located in the Keystone Reclamation site. 2. Future Funding Sources The sewer service charge collected by the City is the primary funding source. The city will continue to utilize the existing funding sources for wastewater facilities. The current fees will need to be reviewed annually and during proposed annexations to ensure that there is sufficient funding to provide wastewater service to increased demand. There are a number of financing mechanisms available to assist in the funding for capital facilities related to the treatment and conveyance of wastewater. Special assessment districts, community facility districts, local bond issuance, developer contributions and development impact fees can be used to fund wastewater treatment and conveyance facilities. Also, there are a number of State and Federal grant and loan programs available such as USDA Water and Waste Disposal Loans and Grants for Public Works and Infrastructure Development and the Regional Water Quality Control Board Clean Water State Revolving Fund. Further descriptions of these and other financing mechanisms are provided under the Financing section. 104 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER IX. DOMESTIC WATER The City of Imperial owns, operates and maintains a system for the treatment, storage and distribution of potable water resources that serves approximately 5,015 (January 2015) water service connections for residences and businesses within the City’s service area and Sphere of Influence. The City purchases all of its untreated water from the Imperial Irrigation District, which is conveyed to City facilities via IID’s Dahlia Canal via a 24-inch diameter raw water pipeline, and the Newside Canal as a secondary source via 27-inch and 16-inch diameter pipelines. All information for this section was acquired from the Master Plan for the Water Distribution System for the City of Imperial prepared by BJ Engineering and Surveying, Inc. and dated 2008. Some of the information provided in this section is paraphrased while other parts are used word-for-word from the Master Plan. Additional information was provided by the City of Imperial Public Works Department. For additional details relating to water facilities, the Master Plan should be consulted. A. Performance Standard Potable water must meet or exceed water quality standards established by the California Department of Health Services and the US Environmental Protection Agency. The California Department of Public Health further requires that specific system pressures be maintained under normal and peak demand conditions. The design criteria are based on Maximum Day Demand (MDD) plus fire flow. The potable water system must be able to adequately treat and provide 150 gallons per person per day as well as fire flow. Although there are no adopted Performance Standards for water distribution, there are design criteria that must be met to ensure that adequate potable water supply and fire flow needs are provided. The design criteria are based on the Maximum Day Demand @ Peak Hour plus fire conditions (MDPHF). Peaking factor is 1.78. The treatment plant capacity shall further meet the demand of the maximum daily flow, plus provide an operational storage capacity of at least 25 percent of the maximum day demand used. Storage required is one maximum average day demand plus a 2,500 GPM fire flow for a four-hour duration. The design criteria includes the following: Table W-1 Water Flow Standards Flow Demand Maximum Pressure Level Velocity Maximum Day Demand + Fire Flow¹ 15.0 FT per second 20 psi – 35 psi Maximum Day Demand 3.0 FT per second 32 psi ≥ 20 psi ¹Fire flow minimums are targeted at 1,200 GPM for residential, 2,000 GPM for commercial, and 2,500 GPM for industrial. 105 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER B. Facility Planning and Adequacy Analysis The City’s Water Treatment Plant was completely rebuilt in 1995 and is located to the west of town, just west of B Street at the north end of the airport runway. Raw water from the Dahlia and Newside Canals is diverted into open reservoirs located at the Water Treatment Plant. This water is then treated through a sedimentation, filtration, and disinfection process in compliance with the Surface Water Filtration and Disinfection Treatment Regulations (Chapter 17, Title 22, California Code of Regulations), the California Department of Health Services, and Local Agency requirements. The City utilizes a number of facilities to treat water to an acceptable level of compliance as noted in Exhibit 12-Existing Water Facilities, and further discussed below. 1. Inventory of Existing Facilities Water Treatment Plant-The City of Imperial Water Treatment Plant currently has a capacity of approximately 7.0 million gallons a day (MGD), which is capable of providing adequate service for the entire City and proposed annexation areas. The Plant is currently operating at 37% capacity. The following is a summary of the present capacity of the individual plant components: Table W-2 Water Plant Facility Capacity by Component Water Plant Component 2015 2015 Total Capacity Each Capacity 24” Diameter Raw Water Gravity Pipeline 10.30 MGD 10.30 MGD 16” and 27” Diameter Raw Water Pipeline 7 MGD 7 MGD Raw Water Reservoirs (3 Total) 10 MGD 10 MGD Raw Water Pump Stations (2) 1.5 MGD ea 3.0 MGD Raw Water Pump Stations (2) 3.5 MGD ea 7.0 MGD Sedimentation Basins (4) 3.5 MGD ea 14 MGD Filter Units (4) 2.5 MGD ea 10 MGD Clean Water Pump Stations (3) 3.6 MGD ea 10.8 MGD Chemical Feed System 6.9 MGD 6.9 MGD Chlorinator 3.4 MGD 3.4 MGD Service Pump Stations (3) 3.6 MGD ea 10.8 MGD Water Storage- The surplus water is currently being stored at the water treatment site in a 2.0 MG storage ground facility. A remote 2.0 MG ground-level storage tank is located at the northeast corner of 13th and O Streets intersection. Another 2.0 MG tank was constructed near Cross Road and Fonzi Road. A future possible 2.0 MG and booster is planned near Barioni Estates. 106 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER Exhibit 12-Existing Water Facilities Map 107 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER Pump Stations-To maintain sufficient water pressure (currently about 57/33 psi), the City has three pump stations. One main station containing three pumps is located at the Water Treatment Plant (WTP) and a smaller station consisting of two pumps is located at the 2.0 MG storage tank at 13th Street and O Street. The third is at the 2.0 MG storage tank at Cross and Fonzi and contains two pumps. The pumps are used to keep water available and to assist when higher pressure is required to fight fires. A standby generator that operates the WTP at half capacity is used during emergencies. Water Pipelines-The existing water distribution system includes 63 miles of pipelines ranging in size from 2” to 16”. However, the minimum water pipeline size for new development is generally 8” and existing pipelines under 4” are earmarked for replacement. Furthermore, a large portion of the existing water distribution system is up to 50 years old. The system contains Asbestos Cement Pipe (ACP) and Polyvinyl Chloride Pipe (PVC). The ACP is the oldest and accounts for roughly 46% of the total pipe length as of 2008. All new pipelines are required to be PVC. 2. Adequacy of Existing Facilities Water Treatment Plant- The water treatment facility is currently operating at 37% of its designed capacity. Since the Water Treatment Plant has a current capacity of 7.0 MGD, the existing facility can provide for an adequate supply of potable water through the year 2025 into several areas planned for annexation and development. Water demand data available for estimating flow rates in the water distribution system consist of total flow from the treatment plant. Based on available Public Works records, the average daily demand from the water plant has varied with monthly averages ranging between 1.7 million gallons per day (MGD) to 1.9 MGD. The average daily demand was determined to be 1.9 MGD to err on the conservative side. Water Storage- The current water storage demand for the City is 4.312 MGD. This number is based on a 3.45 MGD maximum daily flow, derived from the 2007 City of Imperial Service Area Plan, plus 25 percent of the maximum day demand (0.862 MGD), for a total water storage demand of 4.312 MGD. The existing water storage capacity of 6 MG is adequate. Water Distribution System-A computer model of the existing water distribution system was developed by BJ Engineering & Surveying Inc. using available data for the existing facilities and the demand estimates stated above. The capacity of the existing system was evaluated under Maximum Day Demand at Peak- Hour plus fire conditions (MDPHF). The result of the modeling indicates 108 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER that the existing system provides adequate pressure for the Average Annual Demand (AAD) condition, but that during MDPHF conditions many areas of the City experience inadequate pressures. The existing water distribution system is therefore not adequate to serve future development areas outside of the present service area. 3. Future Demand for Facilities Assuming the demand for approximately 150 gallons of potable water per day per capita, the City’s average annual projected water use is as follows: Table W-3 Daily Water Flow Projections 113FF Year Projected Population Average Daily Flow 2020 29,476 4.421 MGD 2025 48,692 7.303 MGD 2030 53,533 8.029 MGD 2035 62,541 9.381 MGD Demand is based on an assumed impact of 150 gallons per day per capita. As previously noted, the City of Imperial average household size is 3.35 persons per household. The average water consumption is 150 gallons per day per person, thus each dwelling units consumes an average of 502.5 gallons per day. Assuming an impact of 502.5 GPD (gallons per day) per Equivalent Dwelling Unit (EDU) on the water treatment facilities, the City was able to project non- residential impacts to water facilities from commercial and industrial operations as follows: Table W-4 Daily Water Flow Projections with EDU’s F113F Planned Total Planned Total Cumulative Non- Cumulative Equivalent Average Daily Flow Year Residential Development Dwelling Demand Equivalent Dwelling Units Units Dwelling Units 2020 8,799 12,170 20,969 10.537 MGD 2025 14,535 16,936 31,471 15.814 MGD 2030 15,980 16,997 32,977 16.571 MGD 2035 18,669 17,057 35,726 17.952 MGD Average Daily Flow is based on an assumed impact of 502.5 gallons per day per EDU. 109 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER 4. Opportunities for Shared Facilities The City does not share water treatment, storage, or distribution facilities with other jurisdictions. There may be an opportunity for an emergency interconnection facility to be planned with the City of El Centro and the Heber Public Utility District. 5. Phasing In order to maintain an adequate water supply for the existing population as well as provide for future development, the following improvements and future facilities are recommended: Short Term Improvements  Install a new 18” diameter waterline from the WTP along La Brucherie Road to the Morningstar Subdivision.  Install a new 12” waterline from northwest side of Sky Ranch Subdivision to the southwest side of Monterey Subdivision.  Install a new 12” waterline from north side of Sky Ranch Subdivision to the south side of Monterey Subdivision to achieve fire demand pressure (1,200 gpm) in this area. 5-10 Year Improvements  Install a new 12” water line from the west water treatment plan reservoir along Banta Road up to Quartz Street on Savanna Ranch Subdivision.  Install a new 12” waterline on 13 th Street to connect across Highway 86 to a 12” waterline located at the east side of the Highway to achieve fire demand.  Construct one additional 2 MG storage tank at the Morningstar Subdivision to insure adequate fire flow pressure. This new tank will include four pumps that must be equal or better than the existing pumps at the WTP.  Install a new 8” waterline from 13 th Street across Highway 86.  Install a new 12” waterline from the WTP to the 2 MG tank located at 14 th Street and Clark road to provide refill capacity.  Install one additional 2 MG storage tank with four pumps near the north east corner of La Brucherie Road and Aten Road. 15-Year Improvements  Install a new 14” waterline from 2 MG storage tank up to Ralph 110 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER Road on the northeast side of Sunset Ranch Estates Subdivision and from there install a 12” waterline along Ralph Road up to Rodeo Drive on the northwest side of Sunset Ranch estates.  Install a new 12” waterline along Cross Road from Paseo Del Sol to Mayfield Subdivision to achieve fire demand pressure in Mayfield Subdivision. C. Mitigation The City of Imperial should continue to pursue various means by which to obtain funding for and to provide for adequate water distribution facilities for the existing and future residents of the City of Imperial. The following are recommendations to achieve adequacy for water distribution facilities: W-1 Facilities identified in the Water Master Plan update shall be constructed as needed as new development and annexation of land occurs. W-2 Prior to the recordation of a final map within any of the annexation areas, a development agreement shall be in place to ensure that adequate water pressures will be provided during the MDPHF conditions for the water distribution system being utilized by said annexation area. W-3 A potable water supply shall be provided for all annexation areas. W-4 Adequate fire flow, subject to the approval of the fire department, shall be provided for all annexation areas. W-5 All system improvements shall be designed and constructed in accordance with Federal, State and local regulations. D. Financing The primary sources of revenue for water treatment and distribution facilities are the water service charges, water capacity fees and water turn on fees. The City will continue to utilize these funding sources in addition to searching for other sources to improve the existing system and in order to meet future demand. The water capacity fee is based on the equivalent dwelling unit (EDU) impact created and funds planned for capital improvements. The City will continue to utilize these funding sources in addition to searching for other sources to improve the existing system in order to meet future demand. 111 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN DOMESTIC WATER 3. Current Costs and Per Capita Costs The current annual cost for the continued maintenance and operation of the water system in the City of Imperial is approximately $256.42 per capita. The 2014 – 2015 City of Imperial budget allocated $4,439,500 for water services. Using the city’s current population of 17,313 residents, operation and debt service of the water facilities cost approximately $256.42 per resident per year. $4,439,500 / 17,313 population = $256.42 per capita Using the City’s current population, the per capita cost of $256.42 for the continued maintenance and operation of the water facilities are noted below in five year increments. Table W-5 Projected Water Costs Year Projected/Planned Water Costs Population 2020 29,476 $7,558,407.09 2025 48,692 $12,485,885.40 2030 53,533 $13,727,242.74 2035 62,541 $16,036,763.22 4. Future Funding Sources The water service charge collected by the City is the primary funding source. These are charges based on the actual water usage. The City will continue to utilize the existing funding sources for water facilities. The current fees will need to be reviewed annually and during proposed annexations to ensure that there is sufficient funding to supply water service to new development. There are a number of financing mechanisms available to assist in the funding for capital facilities related to the delivery of potable water. Special assessment districts, community facilities districts, local bond issuance, developer contributions and development impact fees can be used to fund water treatment and distribution facilities. Also, there are a number of State and Federal grant and loan programs available such as USDA Water and Waste Disposal Loans and Grants for Public Works and Infrastructure Development as well as the State Water Resource Control Board Drinking Water State Revolving Fund. Further descriptions of these and other financing mechanisms are provided under the Financing section of this study. 112 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN FINANCING PLAN I. INTRODUCTION This section of the Service Area Plan discusses various financing mechanisms available to the City of Imperial. It also describes how each existing facility is currently financed and how future financial demands for these facilities can be ensured. Recommended finance plans and available financing options are also discussed. Most financing options discussed in this section are subject to the guidelines of Prop 218. In 1996, Proposition 218, a Constitutional amendment was enacted. Prop 218 clearly defined general taxes and special taxes and set guidelines on the issuance, use, and implementation of taxes. General taxes must be approved by a majority of voters before they can be imposed, extended or increased. Special taxes require approval by a 2/3 vote. II. FINANCING OPPORTUNITIES AND CONSTRAINTS There are many opportunities available to the City of Imperial to finance its present and future facility needs. The following section briefly describes some of the most widely used financing mechanisms. A. Tax Revenue A. General Taxes General taxes generate revenue that is deposited in a City’s General Fund and can be used to support various improvements and services including general government operations, development services, public safety and community services. These revenues can also be used to construct public facilities. The City of Imperial can levy various types of general taxes, which include property tax, franchise tax, sales tax and business license tax. Property taxes generally comprise the largest revenue source for a City, but sales tax revenue can be significant as well depending on the amount and types of business within a City. However, the budget shows almost all general revenue the City generates is utilized for the day-to-day operations of City government, making it necessary to find other ways to finance facilities. B. Gas Tax The State levies a tax on all in-state sales of gasoline. A portion of the revenue derived from the State taxes on gasoline is allocated to cities to be used specifically for the construction, improvement and maintenance of streets and roads. 113 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN C. Tax Levy for Local Bond Issues Local governments can issue general obligation (GO) bonds to finance the acquisition and construction of public capital facilities and real property. These bonds cannot be used for operations and maintenance or to purchase equipment. GO bond measures must be approved by 2/3 of the jurisdiction’s voters. In order to pay back GO bonds, City’s are authorized to impose a property tax levy at the rate needed for repayment of the principal and interest of the bonds. B. Fees 1. Development Impact Fees Development Impact Fees can be a significant funding source to finance large scale public facilities. These fees are intended to ensure that new development pays its proportional share of public facilities based on the impacts created by this new development. In concept, the City charges the development community a series of adopted fees which provide the source of income to pay for capital projects. When enough cash has been assembled, the City constructs capital facility projects in order of priority. Development Impact Fees can be used for the following public facilities:  Police Protection  Fire Protection  Streets & Traffic Signals  Storm Drainage  Water Treatment and Distribution  Wastewater Treatment and Conveyance  General Facilities  Open Space Acquisition, Park Land & Facilities  Public Library 2. User Fees User fees are usually authorized by statute for specific uses and are typically required for monthly service. The fees are used as a revenue source to maintain the systems in proper operating condition and for the construction of facilities needed to meet demand. These fees are charged to patrons or other users on a fee-for-service basis. 3. Motor Vehicle In-Lieu Fee Motor Vehicle in-lieu fees (VLF) are levied by the State for the ownership of automobiles within the State. Funds are then returned to the County based on 114 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN population and distributed by the County to the cities, again, based on population. C. Community/Developer Contributions 1. Developer/Builder Contribution Many of the drainage, sewer, water and circulation improvements required as a result of new development can be directly funded and constructed by the developer and/or builder(s) through private funding sources. Facilities earmarked for developer/builder funding are typically those which normally would have been imposed as a condition of approval of a tentative map under the City's existing development review process. 2. Donations Donations are sometimes available for a specifically cause of facility. The City of Imperial has a donation fund exclusively for the purchase of books. D. Special Assessments/Districts 1. Special Districts Special districts can be formed for the purpose of financing specific improvements for the benefit of a specific area. People within a special district must pay an additional property tax levy or user fees to help repay the bonds issued by the district and finance the district’s ongoing operations. A detailed report prepared by a qualified engineer is required, which must demonstrate that the assessment amount is of special benefit to the parcel upon which the assessment is levied. There are many assessment acts that govern the formation of assessment districts such as the Improvement Act of 1911, Municipal Improvement Act of 1913, Improvement Bond Act of 1915, Benefit Assessment Act of 1982, Integrated Financing District Act as well as other specific facility improvement acts. The provisions of Proposition 218 have altered the procedures and facilities that can be financed through some of these acts. Any assessment district formed must follow all applicable state laws including the provisions set forth in Proposition 218. 2. Fire Suppression Assessment Act (Government Code Section 500078 et seq.) Under this act, a City is allowed to levy assessments on specific parcels or zones for the provision of fire suppression services. A fire suppression assessment does not require the formation of an assessment district, but requires the adoption of an ordinance or resolution in which the parcels or zones subject to the assessment must be identified. In addition, all requirements of Proposition 218 must be met when imposing a fire suppression assessment. 115 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN 3. Community Services District A Community Services District (CSD) can serve as a source of funding for a wide variety of facilities in both unincorporated and incorporated areas. CSDs can levy a range of taxes including ad valorem property tax, general taxes and special taxes, in addition to creating rates and other charges for services. Any fee assessed within a CSD must directly relate to the benefit being received. As a result, a CSD may be broken into zones which only pay for those facilities and services that provide a benefit to that zone. 4. Community Facilities District A Community Facilities District (CFD), not to be confused with a Community Services District, falls under the 1982 Mello-Roos Community Facilities Act. This Act allows a CFD to be established by cities, counties, special districts and school districts to fund a variety of facilities and services. Note that the boundaries of a CFD are not required to be contiguous as they are for a CSD. In order for a CFD to be formed, a public hearing must occur and an election held to authorize the specified tax levy. The special tax levy (Mello-Roos tax) is used to either provide direct funding or pay off bonds. The facilities being funded are not required to be physically located within the boundaries of the CFD. E. State and Federal Funding Various government programs are available at the State and Federal levels to assist local jurisdictions in financing public facilities and services. Most funding sources at the State level require an application requesting assistance and specify the projects or purposes for which the funds can be used. Financial assistance from the state can include grants, low interest loans and matching funds. At the Federal level financial assistance includes grants and federal matching funds for state run assistance programs. State and Federal funding sources include the following: 1. State Funding  Local Law Enforcement Block Grant Program- Grant funds through the State of California (in partnership with Imperial County) for participation in the joint Local Law Enforcement Block Grant Act of 1995, to provide COP’s (Citizens Option for Public Safety) Program to supplement local law enforcement with additional equipment.  State Water Resources Control Board State Revolving Fund Programs- The Division of Financial Assistance (DFA) administers the implementation of the State Water Resources Control Board’s (State Water Board) financial assistance programs that include loan and grant funding for construction of 116 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN municipal sewage and water recycling facilities, remediation for underground storage tank releases, watershed protection projects, nonpoint source pollution control projects, and other similar projects under the Clean Water State Revolving Fund (CWSRF) for potable water treatment facilities and distribution systems. Severely disadvantaged communities can obtain up to 100% grant funding.  California Department of Housing and Community Development- The State Community Development Block Grant (CDBG) program was established by the Federal Housing and Community Development Act of 1974, as amended (42 USC 5301, et seq.). The State CDBG program is implemented by California Health and Safety Code section 50825, et seq, and the California Code of Regulations (Title 25, Section 7050, et seq). The primary federal objective of the CDBG program is the development of viable urban communities by providing decent housing and a suitable living environment and by expanding economic opportunities, principally for persons of low and moderate income. Each year the program makes funds available to eligible jurisdictions through several allocations. Under the General Allocation, jurisdictions may apply for funding to subsidize public facilities or special assessment districts.  California Department of Transportation –The State administers several grant programs including the State Transportation Improvement Program, which are roadway funds allocated for specific and joint decisions of Caltrans and the Imperial County Transportation Commission. The Transportation Development Act (Article 3) funds are other funds granted by the State Transportation Commission for specific projects related to pedestrian, bicycle, and wheelchair mobility. 2. Federal Funding  Federal Highway Administration –The State also administers several federally funded grant programs for roadway safety and improvement including: The Congestion Mitigation and Air Quality Improvement Program (CMAQ). CMAQ funds are available for the specific purpose of developing and implementing transportation programs that reduce traffic congestion and air pollution; The Safe, Accountable, Flexible, and Efficient Transportation Equity Act (SAFETEA). Under this act, federal funding is available for highway, safety, and public transportation programs.  USDA Rural Assistance- There are a number of water, wastewater and community facility loan and grant programs administered through USDA. Under the Community Facilities Direct Loan & Grant Program, rural municipalities with a population of 20,000 or less are eligible for funding of essential community facilities such as first responder vehicles and equipment, 117 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN healthcare, public safety and public services from the Rural Utilities Service (RUS) of the USDA. These facilities may further be used to finance city halls, courthouses, community centers, airports, libraries, homeless shelters, and animal shelters.  U.S. Economic Development Administration - Grants for Public Works and Infrastructure Development. The objective of this grant is to promote economic development and assist in the construction of facilities needed to encourage the creation and retention of permanent jobs in areas experiencing severe economic distress. The facilities can include water and sewer systems, industrial access roads to industrial parks, rail road siding and spurs, tourism facilities, vocational schools, business incubator facilities and infrastructure improvements for industrial parks. The basic grant may fund up to 50% of the cost of the facilities. For communities that are severely depressed, the grant may fund up to 80% of the cost of the facilities.  U.S. Environmental Protection Agency- The Environmental Protection Agency makes low interest loans to communities to assist in the construction of new or upgraded sewage treatment facilities. In partnership with the North American Development Bank it also makes grant funds available through the Border Environmental Infrastructure Fund Program for jurisdictions within 62 miles of the US. Mexico border. EPA’s Border Water Infrastructure Program provides grant assistance to communities along the U.S./Mexico border to develop and construct infrastructure to provide safe drinking water and adequate sanitation, and to improve water quality in shared and trans-boundary waters. EPA funds grant programs through the Border Environmental Cooperation Commission created in 1993 under a side agreement to the North American Free Trade Agreement (NAFTA) for the purpose of enhancing the environmental conditions of the US-Mexico border region. F. Other Financing 1. Financial Institution Financing  California Infrastructure and Economic Development Bank (IBank)- The Infrastructure State Revolving Fund (ISRF) Program provides low-cost financing to public agencies for a wide variety of infrastructure projects. ISRF Program funding is available in amounts ranging from $50,000 to $25,000,000, with loan terms of up to 30 years. Interest rates are set on a monthly basis. Preliminary applications are continuously accepted. 118 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN 2. Lease Financing Instead of purchasing or issuing bonds, agencies can enter into a lease agreement to acquire and dispose of property. Generally, one of two types of lease agreements is entered. The first type is a lease-purchase agreement, where an agency leases a facility while purchasing it. The second type is a sale-leaseback agreement, where a facility is sold to a lessor by an agency, which immediately leases the facility back to the agency. Leases are designed to be tax-exempt investments and a properly constructed lease is not considered a public debt. Lease financing requires finding an investor or group of investors to invest in the return from the agency’s lease payments. Certificates of Participation (COPs) are issued. Certificates of participation refer to the undivided shares of the lease obligation, which are purchased by a group of investors. COPs attract investors because they are designed to be a source of tax-free interest income. If projects are too small to attract investors or to be feasible for lease financing, local agencies can pool COPs. Pooling COPs allows agencies to minimize the costs of initiating and issuing a COP and may reduce the interest required to be paid on the lease. Entities involved with a pooled COP must form a Joint Powers Authority (JPA) to oversee the pooled COP. 119 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN III. FACILITY FINANCING The following section provides a brief discussion of the funding sources used for the specific services and facilities in the City of Imperial. Any sources of funding that are not currently being utilized, as well as opportunities for cost avoidance, are identified. A. Administrative Facilities Current Funding Funding for administrative facilities is currently provided by the General Fund. Specific revenue sources include property and sales taxes, licenses and permits, fines and penalties, charges for services and other miscellaneous sources. Additionally, there are Special Revenue Transfers to the General Fund that directly or indirectly fund administrative services. Large-scale improvement projects would be funded by development impact fees. Cost Avoidance Opportunities In order to reduce administrative services costs, the City of Imperial out sources some of the administrative services such as City attorney, some planning services and special project management. Recommended Funding In addition to the continued use of existing general funding sources, the established development impact fees will help fund future administrative facilities demand created by future development. If additional funding is needed, then General Obligation Bonds can be issued or a citywide community facilities district can be formed. B. Drainage Facilities Current Funding Maintenance of storm water drainage facilities is currently funded by the General Fund, including property and sales taxes, licenses and permits, charges for services and other miscellaneous sources. Future storm water drainage facilities will be installed at the developer/builder’s expense at the time of construction and will be maintained using funds from the General Fund. 120 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN Cost Avoidance Opportunities In order to reduce drainage facilities maintenance and capital improvements costs, the City of Imperial maintains only those storm water conveyance facilities installed by newer development to control storm water runoff. Some services are outsourced such as those capital improvement projects requiring a special projects manager. Recommended Funding Funding for drainage facilities should continue to be borne by developers, while some of the ongoing maintenance can continue to be part of the general fund. Additional funding sources, if needed, should include the creation of a citywide community facilities district, special assessment district or a community services district. C. Fire Facilities Current Funding Costs for the Imperial County Fire Department to provide fire protection services to the City of Imperial are currently financed by property and sales taxes from the General Fund. The City has a Service Contract with the County which is valid for a one year term and the City of Imperial pays the County a set amount per year. Cost Avoidance Opportunities In order to reduce fire protection services costs, the City of Imperial and the Imperial County Fire Department maintain an agreement on a share of costs for fire protection services. The County owns and operate most of the large equipment. The City owns various hoses, nozzles, adapters, breathing apparatus, as well as one 1,250 gallon pumper engine. The County manages all personnel and provides for minor maintenance on all equipment. The City provides insurance and major maintenance on the pumper. Recommended Funding Current use of General Fund as a funding source for fire facilities should continue to be used. In addition, development impact fees have been implemented to ensure costs of future demand created by future development can fund major capital investments. A special fire suppression assessment district or a special tax can also be implemented to assist in the financing of fire facilities costs. 121 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN D. Police/Law Enforcement Facilities Current Funding A portion of financing for police protection is currently financed by property and sales taxes from the General Fund. Other funding sources include the Narcotics Task Force, State C.O.P.S. Grant, State Police Technology Grant and the Local Law Enforcement Block Grant (LLEBG). Development impact fees are also used for larger investments and equipment. Cost Avoidance Opportunities In order to reduce police protection cost, the City of Imperial receives dispatching services from the City of El Centro as a part of the 911 request for emergency response. Recommended Funding Current General Fund and impact fee sources for law enforcement should continue to be used. The development impact fees being collected will ensure future development contributes its proportional share to the future demand created. E. Library Facilities Current Funding Library facilities are currently financed by property and sales taxes from the General Fund and development impact fees. The library also accepts private donations of books and material. Some grant funding has been made available through the California Literacy Campaign Fund. Cost Avoidance Opportunities Although the amounts received are small, the library charges fees for miscellaneous services such as copies of documents or publications. Through inner library programs, the library shares resources with other libraries in the region. Recommended Funding The City should continue using the General Fund as a current funding source for library facilities. Additional funding sources such as community facilities district, special assessment district, Community Block Development Grants, and the State Public Library Fund should be pursued. 122 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN F. Park and Recreation Facilities Current Funding Park and recreational facilities are currently financed by property and sales taxes from the General Fund, developers, and by user fees for recreational activities and pool use. Cost Avoidance Opportunities A parks master plan was being prepared by Wallace Roberts & Todd Planning Design in 2008 but as of 2015 is yet to be completed. The master plan intends to provide implementing measures to upgrade and improve the City’s park system. Recommended Funding Current funding sources should continue to be used as a source for financing park and recreational facilities. It would also be beneficial to develop and implement a five-year capital improvement plan for all park and recreational facilities within the City as recommended by the General Plan. The City should also pursue funding through the State Department of Parks and Recreation. G. Circulation Facilities Current Funding Funding for circulation facilities is provided by the General Fund, Motor Vehicle-In-Lieu Tax, State Gas Tax and the Local Transportation Authority (LTA) Measure D Sales Tax Fund, as development impact fees and developer funding. Developer funding is used to construct required street improvements associated with a specific project. FHWA/CalTrans Grant Programs are also used by the City including Congestion Management Air Quality Grant Fund (CMAQ), State Transportation Improvement Program (STIP), Regional Surface Transportation Program (RSTP), and Transportation Development Account-Article 3 funds. Cost Avoidance Opportunities Although there are no real opportunities to share roadway facilities with any adjacent jurisdiction, the City’s system does not exist independently and circulation within and through the City is mutually affected by the operation of the circulation system along the north end of El Centro, the County roadway system and the State circulation system. The City will continue to cooperate with the City of El Centro, County of Imperial and the State in monitoring the 123 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN operation of the regional system and the implementation of necessary improvements. Recommended Funding Current funding sources for circulation facilities should continue to be used. Additionally, there are several funding mechanisms for circulation facilities such as community facilities district, special assessment district, and Certificate of Participation. There are also a number of additional grant funding programs including the Safe, Accountable, Flexible, and Efficient Transportation Equity Act (SAFETEA), Active Transportation Program (ATP), as well as Community Development Block Grants and other state and federal grants which should be pursued, as suggested by the Circulation Element of the City’s General Plan. H. Wastewater Treatment and Sewer Facilities Current Funding The City used funds from revenue bonds (Wastewater Bond 2012) for expenditures related to improvements and enhancements to the Wastewater Facilities. The primary sources of revenue for wastewater treatment and conveyance facilities are the sewer service charges and sewer connection fees collected in the City’s Enterprise Fund. Operation, maintenance, salaries, and equipment purchases are financed by the Wastewater Enterprise Fund. The sewer service charges function to subsidize off-site facilities such as interceptors and sewer treatment plants. The sewer connection fee is dependent upon the size of the sewer line needed to serve the area and whether the street or alley is paved. Cost Avoidance Opportunities The City often requires developers to construct wastewater-related infrastructure that will connect a specific development with the existing City wastewater system. In order to further reduce wastewater treatment facilities maintenance and capital improvement costs, the City of Imperial out sources services requirement a special project management for some of the City’s wastewater treatment and conveyance system capital improvement projects. Recommended Funding The current fee structure will need to be reviewed annually and during proposed annexations to ensure that there is sufficient funding to provide wastewater service to new development. Special assessment districts, community facilities districts, local bond issuance and development impact 124 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN FINANCING PLAN fees should be considered as alternative funding sources for wastewater treatment and conveyance facilities. Also, State and Federal grant and loan programs are available such as the Water Resources Control Board Clean Water State Revolving Fund and USDA Water and Waste disposal Loans and Grants for Public Works and Infrastructure Development. I. Water Facilities Current Funding The City used funds from revenue bonds (Waster Bond 2012) for expenditures related to improvements and enhancements to the Water Treatment Plant and distribution facilities. The primary sources of revenue for water treatment and distribution facilities are the water service charges, water connection fees and water turn on fees tied to the City’s Enterprise Fund. Operation, maintenance, salaries, and equipment purchases are financed the Water Enterprise Fund. Developer funding is used for specific project water improvements. Cost Avoidance Opportunities The City often requires developers to construct water-related infrastructure that will connect a specific development to the City’s existing potable water system. In order to reduce water facilities maintenance and capital improvement costs, the City of Imperial further out sources services requiring a special projects manager for some of the City’s water treatment and water conveyance system capital improvement projects. Recommended Funding The current fee structure will need to be reviewed annually and during proposed annexations to ensure that there is sufficient funding to supply water service to new development. Special assessment districts, community facilities districts, local bond issuance and development impact fees should be considered as alternative funding mechanisms for water treatment and distribution facilities. State and Federal grant and loan programs should be pursued including the Water Resources Control Board Drinking Water State Revolving Fund and USDA Water and Waste disposal Loans and Grants for Public Works and Infrastructure Development. 125 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN APPENDICES APPENDIX A City of Imperial Adopted Municipal Budget FY 2014-2015 CITY OF IMPERIAL September 2015 SERVICE AREA PLAN APPENDICES APPENDIX B Agreement for Fire Protection Services between County of Imperial and City of Imperial CITY OF IMPERIAL September 2015 SERVICE AREA PLAN APPENDICES APPENDIX C Engineers Opinion of Probable Quantity & Cost Calculation CITY OF IMPERIAL September 2015 Engineers Opinion of Probable Quantity & Cost Calculation 1.
