Municipal Service Review and Sphere of Influence Update
For the Rock Creek Water 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
(SOI) for all applicable jurisdictions in the County. A sphere of influence is defined by
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 identification 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
State Guidelines and Commission policies encourage cooperation among a variety of
stakeholders involved in the preparation of a municipal service review. This MSR will analyze
the existing and future services for the Rock Creek Water District. The MSR will also provide a
basis for the District and LAFCO to evaluate, and if appropriate, make changes to the District’s
Sphere of Influence.

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, such as the Rock Creek Water District, which do not have
the typical municipal-level services to review, this document will be used to determine what type
of services the district is expected to provide and the extent to which it is actually able to do so.
For this special district, the sphere will delineate its service capability and expansion capacity, if
applicable.

Service Review – Rock Creek Water District
Authority
The District was organized under the California Water Code, Division 13, §34000 – 38501
(also known as the “Water District Act”). In addition, the Rock Creek Water District is
considered a “landowner voter district”, as board members are elected by landowners within the
District’s boundaries.
Background
No resource is more vital to California than water. From the agricultural areas, urban centers,
industrial plants, to open space and recreational areas, the distribution of water has been critical
to all land uses.
In California, there are hundreds of special water districts with a great diversity of purposes,
governance structures, and financing mechanisms. Some districts are responsible for one type
of specific duty, as in the case of the water district reviewed in this report, while other districts
provide a wide range of public services.
Purpose
Water Districts that are formed pursuant to the Water District Act may be formed for purposes
such as: to produce, store and distribute water for irrigation, domestic, industrial and municipal
uses; to drain and reclaim lands; to collect, treat and dispose of sewage, waste and storm
water; to generate hydroelectric power; to allocate water to crops and acreage; and, for districts
that adopt a groundwater management plan, to protect groundwater from contamination.
Governance
A five member Board of Directors who are elected by landowners within the District boundaries,
governs the District. Meetings are held on the third Tuesday of each month at 6:00 p.m. at the
residence of Roma Orvis, located at 9601 E. Highway 4.
Formation
The Rock Creek Water District was formed on April 2, 1941.
Location and Size
The District encompasses approximately 1,844 acres, located in the rolling foothills at the base
of the Sierra Nevada Mountain Range, in northeastern Stanislaus County, north of Highway 4.
In 1949, the District annexed the Salt Spring Valley Reservoir, located in Calaveras County and
all of its ditches.
MSR & SOI Update – Rock Creek Water District Page 3
Sphere of Influence
The Rock Creek Water District’s Sphere of Influence (SOI) was originally adopted by the
Commission in 1985. The most recent update, which proposed no changes to the District’s
SOI, was adopted in 2013. The current update serves to reaffirm the District’s SOI, consistent
with Government Code Section 56425. The District’s Sphere of Influence is coterminous with its
current boundaries.
Personnel
The District employs one part-time person, who operates the hydroelectric power generation
facility during irrigation season. The District contracts out for legal, engineering and
bookkeeping services.
Classification of Services
As part of the original MSR completed for the District, the District provided a listing of the
services provided within their boundaries. The District is authorized to provide the functions or
classes of services as identified in this report. Due to recent changes in the Cortese-Knox-
Hertzberg Act, the District would have to seek LAFCO approval to exercise other latent powers
not currently provided.
Services
The District delivers agricultural irrigation water to its customers via the Salt Spring Valley
Reservoir, which is located due east of the town of Milton, in Calaveras County. The District
annexed the reservoir in 1949, which included all of the ditches/pipelines. In addition, the
District also sells irrigation water to one customer outside its Sphere of Influence. This
agreement was part of an original pumping rights contract from the 1940s. The District also
owns and operates a small hydroelectric power generation facility located at one of the main
irrigation ditches. The District is authorized by the Federal Energy Regulatory Commission to
sell power generated by this facility (up to 650 kw hours) to Pacific Gas & Electric (PG&E).
The District is part of a Groundwater Sustainability Agency (GSA) consisting of three regional
partners, the Calaveras County Water District, Stanislaus County and Rock Creek Water
District. The partnership was formed as required by the Sustainable Groundwater Management
Act (SGMA) which requires local agencies with managing sustainable groundwater.
Support Agencies
The District maintains positive collaborative relationships with other agencies, including: Pacific
Gas and Electric (PG&E), California Department of Water Resources, Federal Energy
Commission, the US Fish and Wildlife Service, Calaveras County Water District and Stanislaus
County.
Funding Sources
The District receives assessments and fees for providing agricultural water to its customers.
The District also receives a large portion of its revenue from the sale of hydro-electrical power to
PG&E. Revenues are also received from lease of the resort area near the Salt Spring Valley
Reservoir.
MSR & SOI Update – Rock Creek Water District Page 4
Service Review Categories & Determinations
The following provides determinations related to the seven factors required by Section 56430 for
a Municipal Service Review for the Rock Creek Water District:
1. Growth and Population Projections for the Affected Area
The District serves a rural area, in the northeastern portion of Stanislaus County, north of
Highway 4, in the Rock Creek area. The area is designated as Agriculture on the County’s
General Plan and does not expect any significant population growth. The District currently
serves four retail customers with irrigation water for agricultural purposes. Under a water
rights agreement dating back to the 1940s, the District also serves one customer outside its
boundaries (Groves Ranch).
2. The Location and Characteristics of Any Disadvantaged Unincorporated Communities
Within or Contiguous to the Sphere of Influence
Based on annual median household income and as defined in Section 56033.5 of the
Cortese-Knox-Hertzberg Act of 2000, no Disadvantaged Unincorporated Communities
(DUCs) have been identified within or contiguous to the District’s sphere of influence.
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
At the present time, the District has both the ability and the capacity to serve its service area
and has no unmet infrastructure needs or deficiencies. There are no known DUCs within or
contiguous to the District’s sphere of influence. Additional services, such as sewer,
domestic water and structural fire protection, are provided through other special districts or
by way of private systems.
4. Financial Ability of Agencies to Provide Services
Currently, the District appears to have the necessary financial resources to fund adequate
levels of irrigation service within the District’s boundaries. There is no overlapping or
duplication of services within the District boundaries. The District maintains its rate schedule
to charge the minimum fees as possible.
5. Status of, and Opportunities for, Shared Facilities
At this time, the District does not share any facilities with other districts or agencies.
6. Accountability for Community Service Needs, Including Governmental Structure and
Operational Efficiencies
It is reasonable to conclude that the District can adequately serve the area under its
jurisdiction. A five member Board of Directors, elected by the landowners, governs the
District. The Board conforms to the provisions of the Brown Act requiring open meetings.
The District has a small, yet adequate staff to provide the necessary services to its
customers.
MSR & SOI Update – Rock Creek Water District Page 5
7. Any other Matter Related to Effective or Efficient Service Delivery, as Required by
Commission Policy
None.
MSR & SOI Update – Rock Creek Water District Page 6
Sphere of Influence Update
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 and 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.
The following determinations are made consistent with Government Code Section 56425 and
local Commission policy for the Rock Creek Water District.
Sphere of Influence Determinations
1. Present and Planned Land Uses in the Area, Including Agricultural and Open-Space
Lands
The Rock Creek Water District’s Sphere of Influence (SOI) includes approximately 1,844
acres and is coterminous with the District’s boundaries. Territory within the District
boundaries consists of agricultural and rural land use areas. These uses are not expected
to change. In addition, the District does not have the authority to make land use decisions.
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’s present and probable need for facilities and services in the area is not
expected to change, as the District’s landowners are dependent on the irrigation water they
receive.
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 irrigation water to areas within its
existing sphere of influence.
MSR & SOI Update – Rock Creek Water District Page 7
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
There are no communities of interest within the District boundaries or Sphere of Influence.
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.
No Disadvantaged Unincorporated Communities (DUCs) have been identified within or
contiguous to the District’s Sphere of Influence as defined in Section 56033.5 of the CKH
Act. Additional services, such as sewer, domestic water and structural fire protection, are
provided through other special districts or by way of private systems.
