Colusa Reclamation and Levee Districts
Sphere of Influence Resolution 2010-0009
1 INTRODUCTION
This Sphere of Influence (SOI) report is prepared for the reclamation, drainage, levee
and flood control districts in Colusa County. Although these districts provide similar
services they are not identical and they are formed under different laws. Even though the
districts overlap to some extent; the recommendation is for the sphere of influence for
most districts to remain the same as the existing district boundaries. Reclamation District
(RD) 479 will have an SOI smaller than the District Boundary to allow a detachment.
Colusa County Flood Control and Water Conservation District will also have an SOI
smaller than the District to allow the District to detach the foothill area of the County.
Information contained in this Sphere of Influence is current only as of the date of
adoption.
1.1 LAFCO's Responsibilities
LAFCO’s in California are independent agencies created by the California Legislature in
1963 whose major purposes include encouraging the orderly formation of local
governmental agencies and conserving and preserving natural resources. Statewide
there are 58 LAFCOs working with nearly 3,500 governmental agencies (400+ cities,
and 3,000+ special districts). Agency boundaries are often unrelated to one another and
sometimes overlap at random, often leading to higher service costs to the taxpayer and
general confusion regarding service area boundaries. LAFCO decisions strive to balance
the competing needs in California for efficient services, affordable housing, economic
opportunity, and conservation of natural resources.
LAFCOs are responsible for the following:
1) Coordinating logical and timely changes in local governmental
boundaries
2) Conducting special studies that review ways to reorganize,
simplify, and streamline governmental structure
3) Preparing a review of services called a Municipal Service Review
4) Preparing a Sphere of Influence
LAFCOs thereby determine the future “probable” boundary for each city and special
district within each county. The Commission's efforts are directed toward seeing that
services are provided efficiently and economically while agricultural and open-space
lands are protected. Often citizens are confused as to what LAFCO’s role is. LAFCOs do
not have enforcement authority nor do they have the authority to initiate a city or district
annexation or detachment proceeding. LAFCOs may initiate consolidation or dissolution
proceedings; however, these proceedings are subject to the voter approval or denial.
The Legislature has given LAFCOs the authority to modify any proposal before it to
ensure the protection of agricultural and open space resources, discourage urban sprawl
and promote orderly boundaries and the provision of adequate services.

Adopted September 2, 2010
Colusa Reclamation and Levee Districts
Sphere of Influence Resolution 2010-0009
1.2 Sphere of Influence Requirements
In determining the Sphere of Influence for each local agency, LAFCO must consider and
prepare a written statement of determinations with respect to each of the following:
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 which 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
1.3 Possible Approaches to the Sphere of Influence
LAFCO may recommend government reorganizations to particular agencies in the
county, using the SOIs as the basis for those recommendations. Based on review of the
guidelines of Colusa LAFCO as well as other LAFCOs in the State, various conceptual
approaches have been identified from which to choose in designating an SOI. These
seven approaches are explained below:
1. Coterminous Sphere:
A Coterminous Sphere is a sphere for a city or special district that is the same as its
existing boundaries. Most of the districts in this report will have a Sphere of Influence
that is the same as the district boundary with the exception of RD 479 and the Colusa
County Flood Control and Water Conservation District which will have Detachable
Spheres.
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. This is the recommendation for RD 479 and for the Colusa County
Flood Control and Water Conservation District.
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.
2
Adopted September 2, 2010
Colusa Reclamation and Levee Districts
Sphere of Influence Resolution 2010-0009
5. Consolidated Sphere:
A consolidated sphere includes two or more local agencies and indicates the agencies
should be consolidated into one agency.
6. Limited Service Sphere:
A limited service sphere is the territory included within the SOI of a multi-service provider
agency that is also within the boundary of a limited purpose district which provides the
same service (e.g., fire protection), but not all needed services. Territory designated as a
limited service SOI may be considered for annexation to the limited purpose agency
without detachment from the multi-service provider.
This type of SOI is generally adopted when the following conditions exist:
a. The limited service provider is providing adequate, cost effective and
efficient services.
b. The multi-service agency is the most logical provider of the other
services.
c. There is no feasible or logical SOI alternative.
d. Inclusion of the territory is in the best interests of local government
organization and structure in the area.
Government Code §56001 specifically recognizes that in rural areas it may be
appropriate to establish limited purpose agencies to serve an area rather than a single
service provider, if multiple limited purpose agencies are better able to provide efficient
services to an area rather than one service district.
Moreover, Government Code Section §56425(i), governing sphere determinations, also
authorizes a sphere for less than all of the services provided by a district by requiring a
district affected by a sphere action to “establish the nature, location, and extent of any
functions of classes of services provided by existing districts” recognizing that more than
one district may serve an area and that a given district may provide less than its full
range of services in an area.
7. Sphere Planning Area:
LAFCO may choose to designate a sphere planning area to signal that it anticipates
expanding an agency’s SOI in the future to include territory not yet within its official SOI.
1.4 SOI Update Process
LAFCO is required to establish SOIs for all local agencies and enact policies to promote
the logical and orderly development of areas within the SOIs. Furthermore, LAFCO
must update those SOIs every five years. In updating the SOI, LAFCO is required to
conduct a municipal service review (MSR) and adopt related determinations.
This report identifies preliminary SOI policy alternatives and recommends SOI options
for the reclamation districts and other similar districts. Development of actual SOI update
will involve additional steps as follows:
1) Opportunity for public input at a Colusa LAFCO public hearing
2) Consideration of changes requested by LAFCO Commissioners
3
Adopted September 2, 2010
Colusa Reclamation and Levee Districts
Sphere of Influence Resolution 2010-0009
LAFCO must notify affected agencies 21 days before holding a public hearing to
consider the SOI and may not update the SOI until after that hearing. The Colusa
LAFCO Executive Officer must issue a report including recommendations on the SOI
amendments and updates under consideration at least five days before the public
hearing.
1.5 SOI Amendments and CEQA
LAFCO has the discretion to limit SOI updates to those that it may process without
unnecessarily delaying the SOI update process or without requiring its funding agencies
to bear the costs of environmental studies associated with SOI expansions. Any local
agency or individual may file a written request for an SOI amendment. The request must
state the nature of and reasons for the proposed amendment, and provide a map
depicting the proposal.
LAFCO may require the requester to pay a fee to cover LAFCO costs, including the
costs of appropriate environmental review under CEQA. LAFCO may elect to serve as
lead agency for such a review, may designate the proposing agency as lead agency, or
both the local agency and LAFCO may serve as co-lead agencies for purposes of an
SOI amendment. Local agencies are encouraged to consult with LAFCO staff early in
the process regarding the most appropriate approach for the particular SOI amendment
under consideration.
Certain types of SOI amendments are usually exempt from CEQA review. Examples are
SOI expansions that include territory already within the bounds or service area of an
agency, SOI reductions, and zero SOIs.
SOI expansions for limited purpose agencies that provide services (e.g., fire protection,
levee protection, cemetery, and resource conservation) needed by both rural and urban
areas are typically not considered growth-inducing and are likely exempt from CEQA.
Similarly, SOI expansions for districts serving rural areas (e.g., irrigation water) are
typically not considered growth-inducing.
Remy et al. write
In City of Agoura Hills v. Local Agency Formation Commission (2d Dist.1988)
198 Cal.App.3d480, 493-496 [243 Cal.Rptr.740] (City of Agoura Hills), the court
held that a LAFCO’s decision to approve a city’s sphere of influence that in most
respects was coterminous with the city’s existing municipal boundaries was not a
“project” because such action did not entail any potential effects on the physical
environment.1

2 RECLAMATION DISTRICT 108
2.1 Reclamation District 108 Background
Reclamation District 108 (RD 108) was established in 1870 and delivers water from the
Sacramento River to nearly 48,000 acres of land within northern Yolo County and
southern Colusa County. Reclamation District 108 is one of the first reclamation districts
formed in California that is still in operation. One of the District’s first projects was
construction of the Tisdale Weir on the east side of the Sacramento River to provide
relief from flooding to the levees on the west side of the Sacramento River.
Early in its history the District also addressed the impact of the Knights Landing Ridge
(an area of high ground created by overflow silt deposits from Cache Creek) on drainage
in the Colusa Basin. As a result of a court case, a cut through the Knights Landing Ridge
was made to allow water to flow into the Yolo Bypass when flood waters accumulated
against the Ridge in the lower Colusa Basin.
A significant portion of Reclamation District 108 overlaps with the service area of the
Knights Landing Ridge Drainage District (Yolo County). The primary levee that
Reclamation District 108 is responsible for is the eastern levee along the Colusa Back
Borrow Pit.2

4 RECLAMATION DISTRICT 1004
4.1 Reclamation District 1004 Background
Reclamation District 1004 operates irrigation conveyances with its 23,000 acre
jurisdiction primarily in Colusa County with some land Glenn County. The District is
located east of the Sacramento River with its eastern boundary formed by Butte Creek
along the Colusa-Sutter County Line. Land in the District is farmed primarily to rice.3
The District provides growers with water that is drawn from the Sacramento River at the
Princeton pumping plant to the northwest of the District. Once irrigation water is used, it
drains from fields within the District generally moving to the south and/or east towards
Butte Creek. Water is blocked from draining into Butte Creek by weirs and risers and is
recirculated through the District for reuse. Butte Creek flows into the Sacramento River
at the southern border of the District approximately 5.5 miles downstream from the City
of Colusa.
In addition to agricultural water delivery, the District provides water for habitat
maintenance to the National Audubon Society (NAS) and numerous other landowners
that have established habitat as part of Natural Resources Conservation Service
(NRCS) cost-share programs. Ducks Unlimited (DU) and the California Waterfowl
Association (CWA) have and continue to fund several District facilities, including habitat
areas consisting of permanent ponds, seasonal wetlands, millet fields, and uplands that
provide wintering habitat and resting areas for ducks, geese and shorebirds. The
wetlands produce waterfowl food and the upland areas provide habitat for geese upland
birds and other wildlife species. Habitat land area and water requirements vary from year
to year.4 Typical values are shown below:
Summary of Established Habitat Land and Water Requirements Reclamation District 1004
Name Size Acres Water Requirement (Ac-Ft)
Private Land Owners 2880 8000
National Audubon Society 480 1335
TOTAL 3360 9335
The District employs a staff of water operators who release water from District
conveyances into grower’s fields through gates and valves. The water operators ensure
that enough water is flowing in the laterals to meet demand. Gates and valves in the
delivery system are owned, operated and maintained by the landowners. Each field
within the District and service area has a metered floodgate to determine water usage.5
The District has remained the same except that in 1981, 417 acres were detached.6

5.1 Reclamation District 2047 Background
Reclamation District 2047 was formed in 1919. This District constructed the Colusa
Basin Drain to deal with local flooding in the Colusa Basin. The Drain was originally
conceived to operate as a bypass similar to the Sutter and Yolo Bypasses but now the
Colusa Basin Drain conveys both summer agricultural drainage water (primarily from rice
fields) and winter flows to the Knights Landing outfall gates on the Sacramento River in
Yolo County.7
The District is approximately 30 miles in length, with an average width of 11.5 miles and
covers an area of nearly 230,000 acres.8

9 COLUSA COUNTY FLOOD CONTROL AND WATER CONSERVATION
DISTRICT
9.1 Colusa County Flood Control and Water Conservation District Background
The Colusa County Flood Control and Water Conservation District was formed by an act
of the California State Legislature on September 20, 1983. The District originally
included the entire County of Colusa; however, the area of the County on the East side
of the Sacramento River (42,499 acres) was detached in 1987 by Colusa LAFCO
Resolution 87-04. The Colusa County Board of Supervisors is the Board of Directors for
the District.
The District started to establish two Zones of Benefit, one north of the City of Colusa
along the west side of the Sacramento River and one including part of the City of Colusa
and additional land to the south. However, no tax assessment was ever enacted and the
zones of benefit were never recorded with the State Board of Equalization.11 Since no
tax assessment was established for this District, the Board of Supervisors must fund any
activities with General Fund money. The Board of Supervisors did construct a levee west
of Colusa. The County did have severe flooding problems in 1998 but has not had the
financial resources to deal with these issues.12
9.2 SOI for Colusa County Flood Control and Water Conservation District
The Sphere of Influence for the Colusa County Flood Control and Water Conservation
District should remain coterminous with the previously adopted Sphere which shows
only that land within the Colusa Drainage Basin within the Sphere, excluding the foothill
area of the County. Even though the District has no tax rate at this time they may need
to have one in the future.
9.2.1 SOI Determinations on Present and Planned Land Use for the Colusa
County Flood Control and Water Conservation District Area
1-1] Population growth within the Colusa County Flood Control and Water
Conservation District will be the same as that for Colusa County.
9.2.2 SOI Determinations on Facilities and Services: Present and Probable Need
for the Colusa County Flood Control and Water Conservation District
2-1] The District has not been active and has no facilities.
2-2] If the District does develop a flood control program, only that land subject to
flooding would benefit.

9.2.3 SOI Determinations on Public Facilities Present and Future Capacity for the
Colusa County Flood Control and Water Conservation District
3-1] There may be a need for the District in the future. The District could be used for
a variety of functions. Of particular importance is to assist and manage new
levee improvements to an acceptable level for certification by FEMA to protect
urban uses from 100 year floods
3-2] The District may be able to construct facilities with grant funding. The District
should take the lead is securing funding and construction of levee improvements.
Maintenance of such improvements should rest with existing levee districts.
9.2.4 SOI Determinations on Social or Economic Communities of Interest for the
Colusa County Flood Control and Water Conservation District
4-1] The community of interest is the area within the Colusa Basin Drain within the
County of Colusa, especially in areas subject to flooding.
