VENTURA LOCAL AGENCY FORMATION COMMISSION
STAFF REPORT
Meeting Date: January 21, 2026
TO: LAFCo Commissioners
FROM: Andrea Ozdy, Deputy Executive Officer
SUBJECT: Sphere of Influence Review: LAFCo 26-05S Ventura County Waterworks District
No. 16
Recommendation:
Adopt Resolution LAFCo 26-05S (Attachment 2) making determinations and reviewing the
sphere of influence for Ventura County Waterworks District No. 16 (VCWD 16 or District)
pursuant to Government Code Section 56425(g), including that a sphere of influence update is
not necessary.
District Information:
VCWD 16 is a dependent special district formed in 1972 that, through the Water and Sanitation
Department of the Ventura County Public Works Agency, is authorized to provide wastewater
collection and treatment service throughout its service area within the unincorporated area of
Piru. All other services are considered to be latent.1 The Ventura County Board of Supervisors is
the governing body of the District. VCWD 16’s sphere of influence covers approximately 493
acres (about 0.77 square miles), and its jurisdictional area totals about 358 acres
(approximately 0.56 square miles) (Attachment 1).
Background:
Pursuant to the Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000
(Government Code Section 56000 et seq.), the Commission was required to determine and
adopt a sphere of influence (or “sphere”) for each city and special district on or before January
1, 2008. A sphere of influence is defined in Government Code Section 56076 as the probable
1 Pursuant to Government Code Section 56050.5, “‘Latent service or power’ means those services, facilities,
functions, or powers authorized by the principal act under which the district is formed, but that are not being
exercised, as determined by the commission pursuant to subdivision (i) of Section 56425.”

physical boundary and service area of a local agency, as determined by the Commission. Every
five years thereafter, the Commission must, as necessary, review and update each sphere of
influence (Government Code Section 56425(g)).
In compliance with Government Code Section 56425(g), the Commission accepted a municipal
service review (MSR) report for VCWD 16 first on December 12, 2003, and again on May 18,
2022. Both MSRs are available on the LAFCo website.
LAFCo’s past sphere of influence reviews resulted in the following: (1) an update (i.e.,
modifications) of the sphere in 2004, (2) a review (i.e., no changes) of the sphere in 2009, 2014,
and 2022. The update in 2004 reflected an expansion of the sphere to include approximately
338.6 acres that are outside the District’s jurisdictional area. This area, located north and south
of Center Street, had in the late 1980s been detached from the District and removed from its
sphere based on information available at that time demonstrating that the District did not
provide service within this area. When LAFCo reviewed the District’s sphere in 2004, it
recognized that its prior actions were based on faulty information, and expanded the sphere to
once again include territory that had been continuously served by the District and where the
District operates facilities (i.e., a sewer line in Center Street).
Discussion:
Sphere of Influence Evaluation
Based on the work plan established by the Commission, an evaluation of the District’s sphere of
influence is to be initiated in 2026. LAFCo staff consulted with District staff to discuss the
District’s sphere of influence, and to determine: (1) if the District has experienced any changes
to its service needs or areas since LAFCo’s most recent evaluation of its sphere of influence, and
(2) if District staff anticipates any service changes that would warrant adjustment of the sphere
boundaries.
As explained in the analysis below, it appears that the existing sphere of influence boundary
continues to reflect the District’s current and probable service area, consistent with the MSR
report accepted by the Commission in 2022 (which demonstrates that the District has the
ability to provide services at acceptable levels). Therefore, no changes to the sphere of
influence for the District are recommended. The sphere of influence review involving no
changes is not subject to the California Environmental Quality Act (CEQA) because it “will not
result in a direct or reasonably foreseeable indirect physical change in the environment” (CEQA
Guidelines Section 15060(c)(2)).

Written Determinations
Government Code Section 56425(e) requires that, in determining the sphere of influence of an
agency, the Commission consider and prepare a written statement of its determinations with
respect to each of the following:
(1) The present and planned land uses in the area, including agricultural and open-space lands.
(Section 56425(e)(1))
The District’s sphere of influence consists primarily of urban uses within the Piru
community, and includes some surrounding agricultural land, all within the unincorporated
County area. Based on the land use designations and characteristics of land within the
District’s sphere of influence, land uses within the District’s sphere are expected to remain
unchanged.
(2) The present and probable need for public facilities and services in the area. (Section
56425(e)(2))
VCWD 16 provides wastewater collection and treatment service. The District’s sphere of
influence consists primarily of urban uses within the Piru community, and includes some
surrounding agricultural land, all within the unincorporated County area. The existing need
for District services will remain, and additional demand for services is expected as a result of
eventual community buildout in accordance with the Piru Area Plan.
(3) The present capacity of public facilities and adequacy of public services that the agency
provides or is authorized to provide. (Section 56425(e)(3))
VCWD 16 provides wastewater collection and treatment service. The District’s sphere of
influence consists primarily of urban uses within the Piru community, and includes some
surrounding agricultural land, all within the unincorporated County area. While additional
development within the Piru community is expected, based on the evaluation contained in
the MSR accepted by LAFCo on May 18, 2022, the District has the ability to continue to
provide municipal services within its service area and sphere of influence, and additional
demands would not adversely impact the present capacity of public facilities and adequacy
of public services that the District 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. (Section 56425(e)(4))
The District’s sphere of influence includes Piru, a territory known to be a disadvantaged
unincorporated community (defined in Government Code Section 56033.5 as communities
having an annual median household income that is less than 80 percent of the statewide
annual median household income). The Piru community receives fire protection services

from the Ventura County Fire Protection District, police protection services from the
Ventura County Sheriff’s Office, wastewater collection and treatment services from VCWD
16, and water services from Warring Water Service, Inc., a mutual water company.
Therefore, the sphere of influence review would not result in a detrimental impact to any
social or economic communities of interest.
(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.
(Section 56425(e)(5))
The review of the District’s sphere of influence is not considered an update (i.e., a
modification) to the sphere.
Notice of Public Hearing
This matter has been noticed as a public hearing pursuant to Government Code Section 56427.
