Based on A consolidated sphere includes review of the guidelines of Lake LAFCO two or more local agencies and as well as other LAFCOs in the State, indicates the agencies should be various conceptual approaches have consolidated into one agency. been identified from which to choose in designating an SOI. These seven approaches are explained below) Coterminous Sphere: The sphere for a city or special district that is the same as its existing boundaries. This is the recommendation for the Cobb Area County Water District. 2) Annexable Sphere: A sphere larger than the agency’s boundaries identifies areas the agency is expected to annex. The annexable area is outside its boundaries and inside the sphere. 3) Detachable Sphere: A sphere that is smaller than the agency’s boundaries identifies areas the agency is expected to detach. The detachable area is the area within the agency bounds but not within its sphere. 4) Zero Sphere: A zero sphere indicates the affected agency’s public service functions should be reassigned to another agency and the agency should be dissolved or combined with one or more other agencies. 5) Consolidated Sphere: Cobb County Water District Lake LAFCO Resolution 2009-0009 Sphere of Influence Update Adopted September 16, 2009 2 6) Limited Service Sphere: Moreover, Government Code Section §56425(i), governing sphere A limited service sphere is the determinations, also authorizes a territory included within the SOI of a sphere for less than all of the services multi-service provider agency that is provided by a district by requiring a also within the boundary of a limited district affected by a sphere action to purpose district which provides the “establish the nature, location, and same service (e.g., fire protection), extent of any functions of classes of but not all needed services.

Water loss is the difference between the volume of water pumped from the water supply well and the volume of water sold to users. A loss of water from 10% to 20% is considered acceptable by the American Water Works Association (AWWA).12 3.4 Cobb Area CWD Water Source 3.4.1 Cobb Mountain Area Background The Cobb Mountain Area’s surface water resources are controlled by appropriative and riparian water rights. Diversion of surface waters for use other than on adjacent riparian lands must secure an appropriative permit from the State Water Resources Control Board. Appropriated surface water permits have not been used on a widespread or large-scale basis in the area. As a result, most water used for domestic, commercial and agricultural water supply is groundwater. 10 Brelje & Race Consulting Civil Engineers, “Preliminary Engineering Report Bonanza Springs Water System CSA #7 Lake County Special Districts”, December 2006, p. 10. 11 Brelje & Race Consulting Civil Engineers, “Preliminary Engineering Report Bonanza Springs Water System CSA #7 Lake County Special Districts”, December 2006, p. 11 12.

Average dry-weather flow (ADWF): The 30-day rolling average wastewater flow from May through October. Average wet-weather flow (AWWF): The 30-day rolling average wastewater flow from November through April. California Environmental Quality Act (CEQA): A State Law requiring State and local agencies to regulate activities with consideration for environmental protection. If a proposed activity has the potential for a significant adverse environmental impact, an environmental impact report (EIR) must be prepared and certified as to its adequacy before taking action on the proposed project. Community Facilities District: Under the Mello-Roos Community Facilities Act of 1982 (Section 53311, et seq.) a legislative body may create within its jurisdiction a special tax district that can finance tax-exempt bonds for the planning, design, acquisition, construction, and/or operation of public facilities, as well as public services for district residents. Special taxes levied solely within the district are used to repay the bonds. Community Services District (CSD): A geographic subarea of a county used for planning and delivery of parks, recreation, and other human services based on an assessment of the service needs of the population in that subarea. A CSD is a taxation district with independent administration. Environmental Impact Report (EIR): A report required pursuant to the California Environmental Quality Act that assesses all the environmental characteristics of an area, determines what effects or impact will result if the area is altered or disturbed by a proposed action, and identifies alternatives or other measures to avoid or reduce those impacts. (See California Environmental Quality Act.) Groundwater: Water under the earth’s surface, often confined to aquifers capable of supplying wells and springs. Infiltration: The water entering a sewer system and service connections from the ground, through such means as, but not limited to, defective pipes, pipe joints, connections, or manhole walls. Infiltration does not include, and is distinguished from, inflow. Cobb County Water District Lake LAFCO Resolution 2009-0009 Sphere of Influence Update Adopted September 16, 2009 32 Infiltration and inflow (I&I): The collective term used to describe the extraneous flow in a wastewater collection system from either rainfall-dependent infiltration and inflow or groundwater infiltration. Local Agency Formation Commission (LAFCO): A five-or seven-member commission within each county that reviews and evaluates all proposals for formation of special districts, incorporation of cities, annexation to special districts or cities, consolidation of districts, and merger of districts with cities. Each county’s LAFCO is empowered to approve, disapprove, or conditionally approve such proposals. The LAFCO members generally include two county supervisors, two city council members, and one member representing the general public. Some LAFCOs include two representatives of special districts. Mello-Roos Bonds: Locally issued bonds that are repaid by a special tax imposed on property owners within a community facilities district established by a governmental entity. The bond proceeds can be used for public improvements and for a limited number of services. Named after the program’s legislative authors. Parshall Flume: A Parshall flume has a special shaped open channel flow section that may be installed in a ditch, canal, or lateral to measure the flow rate. The Parshall flume is a particular form of venturi flume and is named for its principal developer, Ralph L. Parshall (Water Measurement Manual, U.S. Bureau of Reclamation, 1984). Sphere of Influence (SOI): The probable physical boundaries and service area of a local agency, as determined by the Local Agency Formation Commission (LAFCO) of the county. Urban: Of, relating to, characteristic of, or constituting a city. Urban areas are generally characterized by moderate and higher density residential development (i.e., three or more dwelling units per acre), commercial development, and industrial development, and the availability of public services required for that development, specifically central water and sewer service, an extensive road network, public transit, and other such services (e.g., safety and emergency response). Development not providing such services may be “non-urban” or “rural”. CEQA defines “urbanized area” as an area that has a population density of at least 1,000 persons per square mile (Public Resources Code Section 21080.14(b)). Cobb County Water District Lake LAFCO Resolution 2009-0009 Sphere of Influence Update Adopted September 16, 2009 33 Urban Services: Utilities (such as water, gas, electricity, and sewer) and public services (such as police, fire protection, schools, parks, and recreation) provided to an urbanized or urbanizing area. Urban Sprawl: Haphazard growth or outward extension of a city resulting from uncontrolled or poorly managed development.

BOX 284, COBB, CALIFORNIA 95426 4/8/09 The District has five (5) sources of water: The following two wells blend together, and are capable of transferring water to all District customers. Well #1 flows between 175 to 250 gallons per minute(250,000 to 360,000 GPD), and is considered our primary water source. Well #3 flows at 90 to 125 gallons per minute (130,000 to 180,000 GPD) blends with Well #1 after treatment for iron, manganese, and SO4 removal. It alone can supply the system, but is considered secondary due to the lower flow rate. Currently Well #3 is off line due to needed maintenance on its filtration system. Well #2 flows at 75 to 125 gallons per minute (108,000 to 180,000 GPD), and is not tied into the main distribution system, and is used to supply between one and two subdivisions depending upon the time of year and the flow rates. Boggs Spring flows at 30 gallons per minute (43,200 GPD), and serves as limited area, and in some months may need to be supplemented from another source. The flow rate has not changed in 25-years regardless of rainfall. Schwartz Spring flows at 135 to 225 Gallons per minute (195,000 to 324,000 GPD), It supplies a limited area, and is the primary backup for the Boggs Spring service area. Schwartz Spring is also committed to supply the Rob Roy Golf Course for irrigation water from May to September (=/-), which can consume as much as one million gallons per week. Our overall capacity ranges from 726,200 GPD to 907,200 GPD including Well 3. Without Well #3 as we are currently running our capacity ranges from 596,200 to 727,200 GPD. We have a total storage capacity of 828,500 gallons in the form of: (2) 200,000-gallon tanks Cobb County Water District Lake LAFCO Resolution 2009-0009 Sphere of Influence Update Adopted September 16, 2009 39 (3) 100,000-gallon tanks (1) 86,000-gallon tank (1) 25,000-gallon tank (1) 17,500-gallon tank For the year 2008 the District customers used 58,494,000-gallons. The greatest usage was in the July/August billing period and totaled 15,110,000- gallons, which averages to 258,233-GPD. The only monthly numbers we have are raw production, which of course a greater than customer use.
