Municipal Service Review and Sphere of Influence Update for the
Denair Community Services District
Introduction
The Cortese/Knox/Hertzberg Local Government Reorganization Act of 2000 Act (CKH Act)
requires the Local Agency Formation Commission (LAFCO) to update the spheres of influence
Government Code 56076 as “...a plan for the probable physical boundary and service area of a
local agency, as determined by the Commission.” The Act further requires that a municipal
service review (MSR) be conducted prior to or, in conjunction with, the update of a sphere of
influence (SOI).
The legislative authority for conducting a municipal service review is provided in Government
Code Section 56430 of the CKH Act. The Act states, that “in order to prepare and to update
spheres of influence in accordance with Section 56425, the commission shall conduct a service
review of the municipal services provided in the county or other appropriate area...” MSRs must
have written determinations that address the following factors in order to update a Sphere of
Influence. These factors were recently amended to include the consideration of disadvantaged
unincorporated communities within or contiguous to the sphere of influence of an agency.
Municipal Service Review Factors to be Addressed
1. Growth and Population Projections for the Affected Area
2. The Location and Characteristics of Any Disadvantaged Unincorporated Communities
Within or Contiguous to the Sphere of Influence
3. Present and Planned Capacity of Public Facilities, Adequacy of Public Services, and
Infrastructure Needs or Deficiencies Including Needs or Deficiencies Related to Sewers,
Municipal and Industrial Water, and Structural Fire Protection in Any Disadvantaged,
Unincorporated Communities Within or Contiguous to the Sphere of Influence
4. Financial Ability of Agencies to Provide Services
5. Status of, and Opportunities for, Shared Facilities
6. Accountability for Community Service Needs, Including Governmental Structure and
Operational Efficiencies
7. Any Other Matter Related to Effective or Efficient Service Delivery, as Required by
Commission Policy
This MSR will analyze the Denair Community Services District. The MSR will also provide the
basis for LAFCO to reaffirm the District’s Spheres of Influence.
MSR & SOI Update – Denair Community Services District Page 1
Sphere of Influence Update Process
A special district is a government agency that is required to have an adopted and updated
sphere of influence. Section 56425(g) of the CKH Act calls for spheres of influence to be
reviewed and updated every five years, as necessary. Stanislaus LAFCO processes municipal
service reviews and sphere of influence updates concurrently to ensure efficient use of
resources. For rural special districts, which do not have the typical municipal-level services to
review, this document will be used to determine what type of services each district is expected
to provide and the extent to which they are actually able to do so. For these special districts,
the spheres will delineate the service capability and expansion capacity of the agency, if
applicable.
The Sphere of Influence for the Denair Community Services District was originally adopted by
the Commission in 1984. The most recent Municipal Service Review and Sphere of Influence
Update, adopted in 2019, proposed no changes to the District’s SOI. The current update serves
to comply with Government Code Section 56425 and will reaffirm the SOI for the district.
Sphere of Influence Determinations
In determining a sphere of influence (SOI of each local agency, the Commission shall consider
and prepare determinations with respect to each of the following factors, pursuant to
Government Code Section 56425:
1. The present and planned land uses in the area, including agricultural open-space
lands.
2. The present and probable need for public facilities and services in the area.
3. The present capacity of public facilities and adequacy of public services that the
agency provides or is authorized to provide.
4. The existence of any social or economic communities of interest in the area if the
commission determines that they are relevant to the agency.
5. For an update of a sphere of influence of a city or special district that provides public
facilities or services related to sewers, municipal and industrial water, or structural
fire protection, the present and probable need for those public facilities and services
of any disadvantaged unincorporated communities within the existing sphere of
influence.
Authority
This review will cover the Denair Community Services District. The District was organized
under Section 61000 et. seq. of the Government Code. In addition, the District is considered a
“registered voter district”, as the board members are elected by the registered voters residing
within the district’s boundaries.
MSR & SOI Update – Denair Community Services District Page 2
Purpose
Community Services Districts may be formed to provide water, sewer, or garbage services, fire
protection, public recreation, street lighting, mosquito abatement, police services, library
services, street improvements, conversion of overhead electric and communication facilities to
underground locations, ambulance services, airport facilities, flood control and transportation
services.
Classification of Services
As part of the previous municipal service review, the District provided a listing of the services
provided within its boundaries. The District is authorized to provide the functions or classes of
services (e.g. water and sewer) as identified in this report. In order to exercise other latent
powers not currently provided, the District would have to seek LAFCO approval.
MSR & SOI Update – Denair Community Services District Page 3
Municipal Service Review – Denair Community Services District
Formation
The Denair Community Services District was formed on October 3, 1961.
Services
The District provides sewer and domestic water services to the community of Denair. In
addition, the District has a contractual agreement with the City of Turlock for sewer disposal
services.
The District also owns and operates the following community service buildings: Community
Center, Gaslight Theatre, Library Building, Senior Center, and Scout Hall.
Capacity
The District currently has the necessary sewer capacity from the City of Turlock to serve
existing and future development within its sphere of influence. City of Turlock is currently in the
process of raising its water treatment rates for the Denair CSD and Keyes CSD by 130%. The
District is currently working on a Prop 218 vote to adjust rates accordingly to help pay for the
increase.
With regards to domestic water, the District currently has four groundwater wells, five lift
stations, and an above-ground steel water tank to serve customers within the existing District
boundaries. Water produced from the District’s wells has consistently met the State’s Title 22
(Code of Regulations) drinking water standards. In order to accommodate significant future
growth within the District’s sphere of influence, installation of additional groundwater wells
and/or pipelines would be necessary.
Location and Size
The District is located in the unincorporated community of Denair, east of the City of Turlock, in
eastern Stanislaus County, and encompasses approximately 694 acres.
Sphere of Influence
The District’s Sphere of Influence (SOI) incorporates approximately 1,056 acres (see Map -
District Boundaries and Sphere of Influence). The original SOI boundary was established by
LAFCO in 1984 to correspond with the Denair Community Plan. In 1998, the County approved
updates to the Denair Community Plan, which maintained the same community planning
boundaries (see Map - Denair Community Plan).
Governance
A five member Board of Directors, elected by registered voters within the District boundaries,
governs the District. Meetings are held on the third Tuesday of each month at 6:00 p.m., at the
District Office, located at 3850 N. Gratton Road, Denair.
The District also has established a website that current information on District programs and
activities (www.denaircsd.org).
MSR & SOI Update – Denair Community Services District Page 4
Personnel
The District has 8 full-time employees. The District also contracts with outside consultants for
engineering, legal, and financial (auditor) services.
Support Agencies
The District maintains collaborative relationships with other agencies, such as the: the City of
Turlock, State Water Resources Control Board, Department of Water Resources, California
Rural Water Association, California Special Districts Association, National Rural Water
Association, and American Water Works Association.
Funding Sources
The District receives funds from monthly user and connection fees, as well as a very small
portion of the shared property tax revenues from Stanislaus County.

Municipal Service Review Determinations
Denair Community Services District
The following are determinations related to the seven factors required by Section 56430 for a
Service Review for the Denair Community Services District:
1. Growth and Population Projections for the Affected Area
The District serves the unincorporated community of Denair. The area is designated in the
Stanislaus County General Plan and Denair Community Plan for residential, commercial,
and industrial uses. The District currently serves an estimated population of 4,865 persons
with water and sewer service.
The Denair community is expected to experience some growth. Stanislaus County has
recently approved subdivision maps which are in the in the process of meeting conditions of
approval and being recorded. Once these maps are recorded, the community will add
approximately 150 lots which could increase the community population by approximately
400-500 residents.
2. The Location and Characteristics of Any Disadvantaged Unincorporated Communities
Within or Contiguous to the Sphere of Influence
Upon review of available Census data, there does not appear to be any communities
meeting the criteria for disadvantaged within or contiguous to the Sphere of Influence of the
District.
3. Present and Planned Capacity of Public Facilities and Adequacy of Public Services,
Including Infrastructure Needs or Deficiencies Related to Sewers, Municipal Water
and Industrial Water, and Structural Fire Protection in Any Disadvantaged,
Unincorporated Communities Within or Contiguous to the Sphere of Influence
The present water and sewer demand within the District’s current boundaries is being met
with existing facilities and infrastructure.
Construction of an above-ground steel water tank (Water Tank No. 1) and associated
booster pumps was completed to help minimize capacity constraints during peak flows, and
to increase fire-flow requirements for the Denair Middle School and surrounding community.
The water tank is adjacent to the existing trunk system which was designed and constructed
in 2005 to provide the District with increased capacity.
The District is finishing a 12-inch water main loop system throughout the entire community to
eliminate pressure zones. The District also plans on switching the water system to a
Supervisory Control and Data Acquisition (SCADA) system, which would allow staff to
collect data to a central location.
The District is also planning on constructing an 8-inch fill line. The line will begin at well No.
8, located at Riopel Avenue and Zeering Road, go west along Zeering Road, south along
Story Road and end at the Corp yard located at the southwest intersection of Kersey and
Story Roads.
MSR & SOI Update – Denair Community Services District Page 6
Within the next three years the District plans on installing a one million gallon water storage
tank at its corporation yard in order to have sufficient water stored for the community.
4. Financial Ability of Agencies to Provide Services
At the present time, the District has the necessary financial resources to fund existing levels
of water and sewer services within the District’s boundaries. There is no overlapping or
duplication of services within these boundaries. The District, on an annual basis, reviews its
rate and fee schedule and attempts to keep the rates and fees as minimal as possible.
The District is currently in the process of completing a Proposition (Prop) 218 vote to
increase rates for both sewer and water. The proposed rates are to respond to a rate
increase from the City of Turlock which treats wastewater for the district.
5. Status of, and Opportunities for, Shared Facilities
The District shares facilities with other agencies as necessary and continually reviews new
opportunities to continue these efforts. For example, the District owns, operates and
maintains the following community facilities: Community Center, Gaslight Theater, Library
Building, Senior Center, and Scout Hall.
6. Accountability for Community Service Needs, Including Governmental Structure and
Operational Efficiencies
A five-member Board of Directors, elected by the registered voters, governs the District.
The District conforms to the provisions of the Brown Act requiring open meetings. The
District website includes meeting agendas and minutes. It appears that the District has the
necessary resources and staffing levels to operate in a cost-efficient and professional
manner.
7. Any Other Matter Related to Effective or Efficient Service Delivery, as Required by
Commission Policy
None.
MSR & SOI Update – Denair Community Services District Page 7
SOI Update – Denair Community Services District
The following determinations for the Denair Community Services District Sphere of Influence
update are made in conformance with Government Code Section 56425 and local Commission
policy.
Determinations:
1. Present and Planned Land Uses in the Area, Including Agricultural and Open-Space
Lands
The District’s Sphere of Influence (SOI) includes approximately 1,056 acres. Territory within
the District boundaries consists of residential, commercial, and industrial land use areas.
These uses are not expected to change. In addition, the District does not have the authority
to make land use decisions within its boundaries. The responsibility for land use decisions
within the District boundaries is retained by the County.
2. Present and Probable Need for Public Facilities and Services in the Area
The District is presently meeting the water and sewer needs of its customers within its
existing service area boundary. The District is planning and making improvements
throughout the district to enhance efficiency, monitoring and maintenance of its
infrastructure.
3. Present Capacity of Public Facilities and Adequacy of Public Services that the
Agency Provides or is Authorized to Provide
The District currently has adequate capacity to provide the necessary water and sewer
services to customers within its existing service area boundary. As mentioned previously,
the District has purchased sewer capacity from the City of Turlock to serve existing and
future development within its sphere of influence. The District is currently working on
completing a Proposition (Prop) 218 vote to adjust its rates accordingly to address City of
Turlock rate increases.
4. The Existence of Any Social or Economic Communities of Interest in the Area if the
Commission Determines That They are Relevant to the Agency
The unincorporated community of Denair is the only community of interest within the District
boundaries. The Turlock city limit is approximately 1.3 miles west of the District’s current
boundaries. The two entities’ Spheres of Influence are approximately 680 feet apart.
5. For an Update of a Sphere of Influence of a City or Special District That Provides
Public Facilities or Services Related to Sewers, Municipal and Industrial Water, or
Structural Fire Protection, the Present and Probable Need for Those Public Facilities
and Services of Any Disadvantaged Unincorporated Communities Within the Existing
Sphere of Influence
As current Census data did not identify any areas qualifying as disadvantaged
unincorporated communities within the District’s Sphere of Influence, no analysis is required
for this determination.
