Sphere of Influence Update
1. INTRODUCTION
1.1 LAFCO's Responsibilities
A Sphere of Influence update is a plan for the probable physical boundaries and service area of a
local agency, as determined by the affected Local Agency Formation Commission (Government
Code §56076). Government Code §56425(f) requires that each Sphere of Influence be updated
not less than every five years as necessary, and §56430 provides that a Municipal Service
Review shall be conducted in advance of the Sphere of Influence update.
Colusa LAFCO has a special policy regarding services, which are not growth inducing and
districts providing non-growth inducing services. The Colusa LAFCO adopted policies and
procedures related to municipal services on February 5, 2004. There were amended by action of
the LAFCO on August 2, 2007. This municipal service review and sphere of influence meets the
criteria contained in Section 3.5 of LAFCO’s adopted policies as follows:
Section 3.5 – Districts and services, which are not growth-inducing
The Commission may prepare abbreviated Municipal Service Reviews and
Sphere of Influence Updates for agencies not providing growth-inducing services
and districts providing non-growth inducing services, waive the requirement for
preparation of a Master Services Element (see Section 3.3 above) and where
appropriate determine Sphere of Influence affirmations to be exempt from the
provisions of the California Environmental Quality Act.
Non-growth-inducing services are defined as all public services except water
conveyance, treatment, extraction and use of ground and (or) surface water for
domestic services or to facilitate urban development; and domestic wastewater
collection, treatment and disposal to facilitate urban development; and fire
protection and road construction and maintenance services.
Districts providing non-growth inducing services normally would serve finite
geographical areas, surrounded by public lands, provide limited specified
services to residents or landowners, have coterminous district/sphere of
influence boundaries and are not generally or routinely considered for
expansion through annexations or sphere amendments for the purpose of
providing services for existing or future urban development.
Non-growth-inducing services is defined as all services excepting
1. water conveyance, treatment, extraction and use of ground and (or)
surface water for domestic services or to facilitate urban development
2. domestic wastewater collection, treatment and disposal to facilitate
urban development
3. fire protection and
4. road improvements and maintenance.
Districts providing non-growth inducing services normally would serve finite
geographical areas, provide limited specified services to residents or
landowners, have coterminous district/sphere of influence boundaries and are
not generally or routinely considered for expansion through annexations or
sphere amendments for the purpose of providing services for existing or future
urban development.
Sphere of Influence Plan reviews and affirmations for districts providing non-
growth inducing services would normally not generate environmental impacts
that would make them subject to heightened level of review California
Environmental Quality Act (CEQA), namely a Negative Declaration or
Environmental Impact Report. Pursuant to CEQA Guideline Section 15320 the
following may be applied, as appropriate.
This section provides for an exemption (class 20) where changes in organization
or reorganization of local governmental agencies (i.e. in the case of a Sphere of
Influence affirmation for districts providing non-growth inducing services)
where the changes do not change the geographical area in which previously
existing powers are exercised.
This exemption may also be applicable where the changes will not result in any
substantive changes to the functions, operations or purposes of the districts; are
not predicated on, or will result in, any land use changes that may be subject to
CEQA review; and will not cause any reasonable foreseeable environmental
consequences in that the Sphere of Influence affirmation will not directly create
or cause any significant land use changes or other actions that could be
detrimental to the environment.
Adoption of a Municipal Service Review precedes LAFCO action on a Sphere of Influence
Update. Given the close relationship between an MSR and Sphere of Influence creation,
amendment or update, the Sphere of Influence is discussed in more detail below.
The Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000 requires the
LAFCO to update the Spheres of Influence for all applicable jurisdictions in its jurisdiction and
update Spheres of Influence, as necessary.

Adopted –Sphere of Influence Update
Colusa Mosquito Abatement District
Resolution 2008-0014
Local governmental agencies, special districts and municipalities must have an adopted Sphere
of Influence (SOI) boundary and territory that define the probable future boundary and service
area of the agency. Inclusion of a particular land area within an agency’s SOI does not
necessarily mean that the area will eventually be annexed. The Sphere of Influence is only one of
several factors LAFCO must consider in reviewing individual proposals (California Government
Code Section 56668 and Colusa LAFCO policies).
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:
• The present and planned land uses in the area, including agricultural and open space
lands;
• The present and probable need for public facilities and services in the area;
• The present capacity of public facilities and adequacy of public services which the
agency provides, or is authorized to provide; and
• The existence of any social or economic communities of interest in the area if the
commission determines that they are relevant to the agency.
1.2 The California Environmental Quality Act
Sphere of Influence Update
A Sphere of Influence may or not be exempt from CEQA. Since the Vector Control District
Sphere of Influence Update is proposed to remain the same as the existing Sphere of Influence
and no environmental impacts will occur as a result of affirming the existing Sphere of Influence,
this Sphere of Influence update would also be exempt from CEQA in this case.

1.3 Sphere of Influence Setting
Colusa County, one of the original California counties, was organized in 1851. Colusa County is
located in the heart of the Sacramento Valley 70 miles northwest of Sacramento. The City of
Colusa, the County seat, is located in eastern Colusa County along the banks of the Sacramento
River.
The climate in Colusa County and the Sacramento Valley, and is generally described as semi-
arid. Rainfall of the region is confined to winter months and varies from 15 to 20 inches per
year. Winters can be very cold for short periods, with heavy frosts and dense fogs. Summers are
hot and dry, with practically no rain from May to September.
Colusa County has a total area of 737,920 acres or approximately 1,149 square miles. The
County is bounded by Glenn County on the north, Yolo County on the south, Butte County and
Sutter County on the east, and Lake County on the west.
Sutter County was also one of the original counties of California, created in 1850 at the time of
statehood. Sutter County was named after General John Sutter, a Swiss citizen, who obtained a
large land grant from the Mexican government, and called his first settlement New Helvetia
(now the City of Sacramento). In 1841, the general established a great stock ranch in this area to
which he retired in 1850 when gold seekers deprived him of most of his holdings at Sacramento.

2. SPHERE OF INFLUENCE
The Colusa Mosquito Abatement District includes approximately 140 square miles. The Sphere
of Influence would include the valley area of Colusa County and would allow the District to
annex this area of 472 square miles.
2.1 Land Use
2.1.1 Present and Planned Land Uses in the Area, Including Agricultural and Open
Space Lands
The Colusa County General Plan, the City of Colusa General Plan and the Sutter County General
Plan govern the land use within the existing District Boundary. The existing District includes the
Colusa National Wildlife Refuge. The Sphere of Influence area would include the Delevan
National Wildlife Refuge.
The Colusa County General Plan and the City of Williams General Plan govern the land use
within both the existing and proposed Sphere of Influence for the district.
The land within the Sphere of Influence is primarily designated for agriculture. The communities
of Arbuckle and Maxwell are designated for residential, industrial and commercial land uses as
is the City of Williams and several small communities throughout the valley area.
2.1.2 SOI Determinations Present and Planned Land Use
1-1) There is a need for mosquito abatement services within the area shown in the Sphere of
Influence.
1-2) The Colusa Mosquito Abatement District is the appropriate service provider for mosquito
abatement services within the Sphere of Influence area.
1-3) The Sphere of Influence shows a logical area to be annexed to the CMAD.
2.2. Municipal Services: Present Need
2.2.1 Service Need
There is a need for mosquito abatement services within the Sphere of Influence area to combat
the West Nile Virus. There has been at least one death from the West Nile Virus in the Sphere
area in 2007. The area is similar to the area within the District and includes many rice fields and
other areas which provide mosquito habitat.

Resolution 2008-0014
2.2.2 SOI Determinations for Facilities and Services: Present and Probable Need
2-1) There is a need for mosquito abatement services in the SOI area. These services can best
be provided by the Colusa Mosquito Abatement District.
2-2) The need for mosquito abatement services will continue for the foreseeable future
because the majority of the land is zoned for agriculture.
2.3 Public Facilities Future Capacity
2.3.1 CMAD Facilities and Capacity
The Colusa Mosquito Abatement District has the facilities to serve additional area. Additional
staff would be required at the technician level on a seasonal basis. The management staff would
be able to manage the services for a larger area.
2.3.2 SOI Determinations for Public Facilities Present and Future Capacity
3-1) Voters and (or) landowners within any area to be annexed to the District would more
than likely have to vote to pay the same property tax and (or) parcel fees as the
landowners within the District.
3-2) With appropriate funding, the District would have the facilities and capacity to serve the
area within the Sphere of Influence.
2.4 Social or Economic Communities of Interest
2.4.1 Colusa and Sutter Counties
The Colusa Mosquito Abatement District includes the area around the City of Colusa which
represents a community. However, the problem of mosquito abatement and the prevention of
West Nile Virus extends beyond the District boundaries.
Since the Colusa Board of Supervisors appoints four of the Directors for the District and the
geography of the area is similar, it would be appropriate to include the valley area of Colusa
County within the Colusa Mosquito Abatement District.
2.4.2 SOI Determinations for Social or Economic Communities of Interest
4-1) LAFCO is charged with overseeing orderly development in an area. The County and its
cities are charged with land use planning.
4-2) The larger area shown in the SOI would still constitute a community of interest for
mosquito abatement
