City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
I. INTRODUCTION
A. Local Agency Formation Commissions
Local Agency Formation Commissions (LAFCOs) are political subdivisions of the State of
California and are responsible for administering a section of Government Code now known
as the Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000 (“CKH”).
LAFCOs are located in all 58 counties and are delegated regulatory responsibilities to
coordinate the logical formation and development of local governmental agencies and
services. Specific regulatory duties include approving or disapproving proposals involving
(a) city incorporations or disincorporations, (b) special district formations, consolidations,
and dissolutions, and (c) city and special district annexations and detachments. LAFCOs
inform their regulatory duties through a series of planning activities, namely preparing
municipal service reviews and sphere of influence updates. Underlying LAFCOs regulatory
and planning responsibilities is fulfilling certain objectives outlined by the California
Legislature under Government Code (G.C.) Section 56301, which states:
“Among the purposes of the commission are discouraging urban sprawl, preserving open-space and prime
agricultural lands, efficiently providing governmental services, and encouraging the orderly formation and
development of local agencies based upon local conditions and circumstances.”
LAFCOs are generally governed by a five-member commission comprising two county
supervisors, two city councilmembers, and one representative of the general public.1
Members must exercise their independent judgment on behalf of the interests of residents,
landowners, and the public as a whole. LAFCOs have sole authority in administering its
legislative responsibilities and its decisions are not subject to an outside appeal process.
B. Spheres of Influence
A central planning responsibility for LAFCO is
“Sphere” means a plan for the probable
the determination of a sphere of influence
physical boundary and service area of a
(“sphere”) for each city and special district under
local agency, as determined by LAFCO.
its jurisdiction.2 LAFCO establishes, amends, and
updates spheres to designate the territory it believes represents the appropriate and probable
future service area and jurisdictional boundary of the affected agency. All jurisdictional
changes, such as annexations and detachments, as well as outside service extensions must be
consistent with the spheres of the affected local agencies with limited exceptions.3
There are several important and distinct policy considerations underlying sphere
determinations. For example, inclusion within a multiple-purpose agency’s sphere, such as a
city or community services district, generally indicates an expectation by LAFCO the
territory should be developed for urban uses. Alternatively, inclusion of territory within a
limited-purpose agency’s sphere, such as a hospital or mosquito abatement district, may be
intended to support both urban and non-urban uses. It is also important to note inclusion
1 Several LAFCOs also have two members from independent special districts within their county. Each category
represented on LAFCO has one alternate member.
2 LAFCOs have been required to determine spheres for cities and special districts within its jurisdiction since 1972.
3 A prominent exception involves land owned and used by cities for municipal purposes that are non-contiguous to their
incorporated boundary (G.C. Section 56742).

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
within a sphere does not provide any guarantees the territory will be annexed. Jurisdictional
changes must be considered on their own merits with particular attention focused on
assessing whether the timing of the proposed action is appropriate.
Sphere determinations may also lead LAFCO to take other actions under its authority. This
may include initiating the formation, consolidation, or dissolution of local agencies. Further,
an increasingly important role involving sphere determinations relates to their use by
regional councils of governments as planning areas in allocating housing need assignments
for counties and cities, which must be addressed by the agencies in their housing elements.
LAFCO must review and update each local agency’s sphere every five years as necessary.
In making a sphere determination, LAFCO is required to prepare written statements
addressing four specific planning factors listed under G.C. Section 56425. These factors
range from evaluating current and future land uses to the existence of pertinent communities
of interest. The intent in preparing the written statements is to focus LAFCO in addressing
the core principles underlying the sensible development of each local agency consistent with
the anticipated needs of the affected community. The four factors are outlined below.
1. Present and planned land uses in the area, including agricultural and open-space.
2. Present and probable need for public facilities and services in the area.
3. Present capacity of public facilities and adequacy of public services that the agency
provides or is authorized to provide.
4. Existence of any social or economic communities of interest in the area if the
commission determines that they are relevant to the agency.
LAFCOs inform their sphere determinations by preparing municipal service reviews to
evaluate the level and range of governmental services provided in the region. Municipal
service reviews vary in scope and can focus on a particular agency, service, or geographic
area. Municipal service reviews culminate with LAFCO making determinations on a number
of governance-related factors. This includes infrastructure needs or deficiencies, growth and
population projections, and financial standing. LAFCOs may also consider additional
factors if required by local policy. LAFCOs must complete the municipal service review
process prior to making related sphere determinations.
C. City of American Canyon
This report represents LAFCO of Napa County’s (“Commission”) scheduled sphere review
of the City of American Canyon. The report supersedes the last comprehensive sphere
review of American Canyon adopted by the Commission in February 2004. This report
draws on information collected and analyzed in the Commission’s recently completed
municipal service review on the southeast county region, which included evaluating the
availability, adequacy, and capacity of services provided by American Canyon. Other
governmental agencies evaluated in the southeast county municipal service review were the
American Canyon Fire Protection District (ACFPD) and County Service Area (CSA) No. 3,
whose spheres will be updated in the near future as part of separate reports. The municipal
service review’s executive summary is attached and includes the written determinations
adopted by the Commission at its June 1, 2009 meeting.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
The focus of this report is to consider whether changes to American Canyon’s sphere are
warranted in terms of consistency with the provisions of CKH and the adopted policies and
administrative practices of the Commission. In identifying study areas for review, the report
incorporates a request made by American Canyon to expand the City’s sphere to correspond
with its recently revised urban limit line. The report also considers two separate agreements
between American Canyon and the County providing consensus for adding certain lands to
the City’s sphere. The affected lands are identified in this report as Study Area “A” and the
Town Center portion of Study Area “E.” These agreements have been submitted to LAFCO
in accordance with G.C. Section 56425(b). This statute directs LAFCO to “give great
weight” to the agreements to the extent they are consistent with its policies in its final
determination of the subject agency’s sphere.

II. AGENCY OVERVIEW
A. Background
American Canyon was incorporated in 1992 and operates under a council-manager system of
government. American Canyon is approximately 4.9 square miles in size and provides a full
range of municipal services directly or through contracts with outside contractors with
limited exceptions. American Canyon is the second largest municipality in Napa County and
has been one of the fastest growing communities in the entire San Francisco Bay Area with
an average annual population increase of 7.2% over the last 10 years. The California
Department of Finance estimates American Canyon’s population at 16,293. This amount
represents an approximate two-third increase in population since 1998.
American Canyon’s current operating budget is $16.5 million. American Canyon’s primary
revenue source is drawn from property taxes, which currently fund nearly half of the City’s
operating budget. Markedly, on a regional level, American Canyon collects more in property
taxes than any other city in Napa County as measured on a per capita basis.4 American
Canyon’s remaining discretionary revenues are principally generated from sales tax and
motor vehicle license fees, with the former having increased by over one-third over the last
five years as result of new commercial development in the City. This includes the recent
construction of the first two phases of Napa Junction, which represents American Canyon’s
largest commercial site and anchored by a Wal-Mart Superstore.5 The single largest
operating expense for American Canyon involves police protection services and presently
represents close to one-quarter of all discretionary expenditures. American Canyon’s
projected operating fund balance at the end of the 2008-2009 fiscal year is $4.3 million.
American Canyon operates two municipal enterprises involving sewer and water services.
Both systems extend beyond American Canyon’s incorporated boundary and were inherited
by the City at the time of its formation as successor agency to the American Canyon County
Water District (ACCWD). In 2001, G.C. Section 56133 became effective to mandate local
agencies receive LAFCO approval before providing new or extended services beyond their
jurisdictions by contract or agreement with local landowners. The statute limits LAFCO
approval for new or extended services beyond the agency’s jurisdiction but within their
spheres in anticipation of future annexations. Approval for new or extended services beyond
an agency’s jurisdiction and sphere is limited to addressing existing or impending public
health or safety threats. In response, the Commission reconciled the requirements of the
statute with American Canyon’s inherited responsibilities by establishing extraterritorial
sewer and water service areas for the City. The sewer and water extraterritorial service areas
extend north of American Canyon to include unincorporated lands designated for an urban
use by the County of Napa to Fagan Creek and Soscol Ridge, respectively.6
4 Based on actual 2007-2008 totals, American Canyon received $424 in property tax revenues, which surpassed St. Helena
at $382, Calistoga at $285, Napa at $263, and Yountville at $135.
5 A third phase of Napa Junction is expected to add an additional 130,000 feet in commercial space.
6 American Canyon must receive Commission approval before providing new or extended services within the
extraterritorial service areas with the exception of land subject to the County’s Airport Industrial Area Specific Plan.

B. Sphere of Influence
Establishment
American Canyon’s sphere was established by the Commission in 1991 in conjunction with
approving the City’s incorporation. The Commission designated the sphere to closely match
American Canyon’s approved incorporated boundary with the notable addition of
approximately 410 unincorporated acres located along the City’s eastern border.7 This
unincorporated area was added to the sphere given its urban land use designation under the
County General Plan, which was based on following the perceived 15% slope line of the
adjacent Sulpher Mountain range. Two incorporated areas not included in the sphere
involved American Canyon’s water treatment plant located off of Kirkland Ranch Road and
its wastewater storage ponds situated at the western terminus of American Canyon Road.
Amendments/Updates
The Commission has approved three changes to American Canyon’s sphere since its
establishment in 1991. The first two changes to the sphere involved amendment requests
made by individual landowners. The first amendment was approved in 1998 and added 25
acres located southeast of American Canyon Road’s intersection with Flosden Road. This
area was added as part of a concurrent annexation proposal and represents the far eastern
portion of the present-day La Vigne subdivision. The second amendment was approved in
1999 and added 70 acres located east of State Highway 29’s intersection with Poco
Boulevard. This area was added to facilitate a future annexation of a town center project
and is commonly referred to as the “horseshoe” area. The area remains unincorporated and
undeveloped. The third change to the sphere was approved by the Commission in 2004 as
part of a scheduled comprehensive update. The update included adding four distinct areas
to the sphere totaling 640 acres. The largest addition involved over 370 acres located along
the northern side of Green Island Road, which was later annexed into American Canyon in
2005, although it remains undeveloped or underdeveloped. The other additions to the
sphere involved areas located off of Watson Lane, Eucalyptus Drive, and American Canyon
Road and generally remain unincorporated.8
Current Composition
American Canyon’s sphere is currently 3,333 acres or 5.1 square miles in size. The sphere is
coterminous with nearly 90% of American Canyon’s incorporated boundary and includes a
total of 5,214 assessor parcels. Of this amount, 18 assessor parcels are unincorporated and
concentrated within four distinct areas. Three of these four unincorporated areas were
added to the sphere in 2004 as part of the last comprehensive review. The fourth area,
which consists of three assessor parcels located east of the intersection of State Highway 29
and Poco Boulevard, was added to the sphere in 1999 and is part of a planned town center
project. Figure One depicts the current composition of the sphere. Figure Two highlights
the four unincorporated areas within the current sphere.
7 American Canyon’s incorporated boundary was established by the Commission to generally follow ACCWD’s jurisdictional
boundary with the exception of lands designated for non-urban use by the County.
8 A portion of the area along Eucalyptus Drive was annexed into American Canyon in 2005 as part of the City’s
construction of a new wastewater treatment plant.

C. Land Use Policies
American Canyon
The American Canyon General Plan was adopted in 1994 and codifies land use objectives
and policies for the City through 2010. The General Plan includes a vision statement for
American Canyon to evolve into a “compact urban community surrounded by a well-defined
network of farmlands, hillsides, and riverine habitats.” The General Plan outlines four broad
development goals: (a) serve as a bedroom community for the greater region; (b) create a
sufficient commercial base for residents; (c) become a subregion employment center; and (d)
emerge as a destination for visitors to the Napa Valley.
11
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
The American Canyon General Plan includes an urban limit line (ULL) that was recently
amended as part of a negotiated agreement with the County and implemented through a
citizens’ initiative.9 The ULL directs American Canyon’s future growth through 2030 to
extend north to the southern perimeter of the Napa County Airport and east towards the
foothills of the Sulpher Mountain range. All lands within the ULL are assigned land use
designations. These designations orient American Canyon’s development to emphasize
predominately residential uses in the southwest and southeast while commercial and
industrial uses are generally planned in the central and northwest. Figure Three shows
American Canyon’s General Plan Map.
Figure Three
9 The agreement between American Canyon and the County was entered into on June 3, 2008. The agreement stipulates
the County will support the expansion of American Canyon’s sphere and subsequent annexation of lands lying north of
the City and within its ULL identified in this report as Study Area “A.” In exchange, American Canyon pledges it will
provide water service to outside customers within the County’s Airport Industrial Area Specific Plan. American Canyon
further agrees not to file an additional sphere amendment request with the Commission through 2030 other than the
City’s standing application on file to expand the sphere to match its revised ULL.

County
The County General Plan was last updated in 2008 and designates nearly all adjacent
unincorporated lands east and west of American Canyon as Agriculture, Watershed and Open
Space. This designation supports the preservation of existing agricultural and open-space
land uses characterizing most of the area by requiring minimum lot densities of 160 acres.
Contemplated uses under this designation include agriculture, processing of agricultural
products, and single-family residences with or without a detached second unit.10 Adjacent
unincorporated land north of American Canyon is designated under the County General
Plan as Industrial. This designation specifies minimum lot densities between 0.5 to 40 acres
based on proximity to utilities and is intended to support various industrial uses, including
warehouses, manufacturing facilities, and wineries.11 Figure Four shows the County’s
General Plan Land Use Map.

III. DISCUSSION
A. Objectives
The basic objective of this report is to identify and evaluate areas warranting consideration
for inclusion or removal from American Canyon’s sphere as part of a comprehensive review.
Underlying this effort is to designate the sphere to facilitate the sensible and timely
development of American Canyon consistent with the provisions of CKH. Specific goals
under this legislation include discouraging urban sprawl, preserving open-space and prime
agricultural lands, and providing for the efficient extension of governmental services.
The Commission’s “Policy Determinations” were last amended in 2003 and provide
prescription in fulfilling its legislative objectives. The Policy Determinations highlight the
Commission’s commitment to avoid the premature conversion of designated agricultural or
open-space lands to urban uses through a series of restrictive allowances. This includes a
determination to exclude lands designated as agricultural or open-space from city spheres for
the purpose of accommodating urban type development unless it is demonstrated that infill
opportunities are limited or non-existent. An additional determination states the
Commission will recognize the public’s support for Measure “J” by deferring to the County
General Plan in determining agricultural and open-space land use designations.12 The
Commission also directs any development or use of land for purposes other than open-space
shall be guided away from existing prime agricultural lands.
B. External Considerations
Spheres have assumed an increasingly important role in informing statewide and regional
planning activities that are external to LAFCOs, but parallel shared goals with respect to
coordinating efficient and sustainable growth. The use of spheres, for example, by local
council of governments (COGs) as the planning areas for purposes of preparing biannual
population, jobs, and housing projections is significant. These projections are used by
COGs in allocating regional housing needs assignment (RHNA) among cities and counties
within their regions as assigned by the Department of Housing and Community
Development. Importantly, depending on the COGs allocation process, the placement of
unincorporated land within a city sphere with potential job growth may result in an increased
RHNA to the municipality as part of the next cycle.13 Conversely, the placement of
unincorporated land within a city sphere with potential housing growth may result in a
decreased RHNA to the municipality. Agreements among local agencies may also have an
effect on the allocations. Regardless, central to the allocation process is the sphere.
A more recent external consideration associated with spheres relates to Senate Bill 375,
which was enacted in January 2009. This legislation now requires regional transportation
agencies to establish sustainable community strategies (SCS) as part of their regional
transportation plans. The end-goal of a SCS is to connect smart growth land use principles
with transportation funding in order to further reduce greenhouse gas emissions in the state.
The law requires consideration of adopted spheres in the development of a SCS.
12 Measure J was enacted by Napa County voters in 1990 and prohibits the amendment of agricultural or open-space land
use designations in unincorporated areas without electorate approval through 2020. This initiative was extended in 2008
through 2050 through Measure “P.”
13 COGs’ housing need allocation currently cycles every seven to eight years.
14
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
C. Timeframe
State law requires LAFCOs review and update each local agency’s sphere by January 1, 2008
and every five years thereafter as needed. Accordingly, it has been the practice of the
Commission to update each local agency’s sphere in a manner emphasizing a probable five-
year annexation area. This update’s analysis is consistent with this practiced timeframe.
IV. STUDY AREAS
A. Criteria and Selection
This report incorporates a formal request made by American Canyon to expand the sphere
to match its revised ULL. As described on page 12 of this report, the amended ULL was
formulated as part of a negotiated agreement between American Canyon and the County and
implemented through a citizens’ initiative adopted by the City Council in August 2008. The
ULL is intended to guide American Canyon’s growth through 2030 and includes a total of
777 unincorporated acres lying outside the current sphere. This report categorizes these
unincorporated ULL lands within five distinct study areas based on geographic similarities
and are identified as “A,” “B,” “C,” “D,” and “E.” A sixth study area, “F,” has also been
included for review by staff given the affected unincorporated lands are surrounded nearly
four-fifths by American Canyon’s ULL.
A potential seventh study area was also considered for conclusion in this review and update.
This area comprises 155 unincorporated acres of mostly industrial land uses located along
Green Island Road between American Canyon and the Napa River. Although it is outside
the ULL, the area lies within American Canyon’s extraterritorial water and sewer service
areas as determined by the Commission. All vehicular access to the area must also go
through American Canyon byway of Green Island Road. These preliminary factors all
suggest including the area into the sphere is merited. Previous outreach efforts made during
the last update, though, identified a sizeable portion of the landowners in the area opposed
inclusion into the sphere. It is reasonable to assume this opposition continues today given
the perceived lack of landowner change in the area. With this opposition in mind, and given
the five-year timeframe, consideration of expanding the sphere to include the area is not
further considered as part of this review.
Additionally, no study areas have been identified for review with respect to considering
removal of any of the four existing unincorporated areas from the sphere. The rationale for
not considering removals is prefaced on recognizing all four unincorporated areas are subject
to current or impending annexation proposals.

V. ANALYSIS
A. Evaluation Factors
Evaluation of each study area is organized to address the four planning factors the
Commission is required to consider anytime it makes a sphere determination. These
planning factors are (a) present and planned uses, including agricultural and open space
lands, (b) present and probable need for public facilities and services, (c) present adequacy
and capacity of public services, and (d) existence of any social or economic communities of
interest. Conclusions are offered for each study area with regard to whether a sphere
modification is appropriate based on the accompanying analysis.

B. Study Areas
Study Area A
This study area comprises approximately 293 unincorporated acres located immediately
north of American Canyon’s existing jurisdictional boundary and sphere and south of the
Napa County Airport. The study area includes four entire assessor parcels and is bisected
along its eastern side by an active railroad owned by Union Pacific. The affected assessor
parcels are commonly referred to by their current or former landowner’s names, “Atkins,”
“Headwaters,” and “Panattoni.” The study area was included in American Canyon’s original
ULL and is considered for inclusion into the sphere at the request of the City and supported
by the County as part of a August 2008 agreement.

The entire study area is presently undeveloped and consists of native grassland. There is no
documentation or evidence indicating the study area has been developed or utilized in the
past for any uses other than perhaps livestock grazing.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
County Land Use Policies
The County designates the entire study area as Industrial and contemplates a variety of urban
non-residential uses ranging from manufacturing to office space.14 The designation is
supported by the County’s zoning standard of Industrial Park for all four of the affected
assessor parcels, which specifies a minimum lot requirement of 5.0 acres. Specific
development and design standards for the study area are outlined in the County’s Airport
Industrial Area Specific Plan (AIASP).15 The County General Plan was updated in 2008 to
illustrate the entire study area as part of American Canyon’s ULL. This illustration reflects
the County’s expectation the entire study area will be eventually developed for urban type
uses within American Canyon.
American Canyon Land Use Policies
American Canyon also designates the entire study area as Industrial and has prezoned the
affected assessor parcels as Napa County Airport Industrial Area. This prezoning standard has
been made in conjunction with filing an annexation proposal with the Commission and fully
incorporates the development and design standards codified in the County’s AIASP. The
prezoning standard ensures future uses and densities within the study area would be identical
under either jurisdiction.
Development Projects
There are two vested projects tied to the study area. The first project involves the smaller of
the two contiguous affected assessor parcels referred to as the Panattoni property. The
project was approved by the County Planning Commission in April 2008 and allows for the
construction of four detached light industrial buildings totaling 171,000 square feet.16 The
second vested project involves subdividing the largest of the four affected assessor parcels
referred to as the Headwaters property. This project was approved by the County Planning
Commission in January 2009 and allows for the creation of a new 40 acre lot and the
construction of a 645,000 square foot warehouse and distribution facility adjacent to the
western side of the Union Pacific railroad track.17 Both projects are currently dormant, but
are expected to be completed within the timeframe of this review. These vested projects
would not be affected by annexation.
14 The minimum lot requirement under the County’s Industrial designation is 0.5 to 40 acres based on utility and road access.
15 The County’s AIASP guides growth management within the surrounding 3,000 acre area through 2025.
16 The County has received a separate application to construct a 279,000 square foot warehouse and distribution facility on
the larger of the two contiguous parcels comprising the Panattoni property. The application is on hold.
17 This vested project has been modified from an earlier approval by the County Planning Commission in 1999 to allow the
entire Headwaters property to be developed by the prior landowner (Beringer) to include a 1.4 million square foot
warehouse for winery production and storage along with a commercial vineyard.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
Additional Land Use Factors
The study area does not qualify as agricultural or open-space land under LAFCO law.18
There are also no existing agricultural contracts tied to the four affected assessor parcels.
The study area does lie within the Napa County Airport’s Compatibility Zone D, which
marks the lands are routinely overflown by aircraft ranging in altitude between 300 to 1,000
feet above ground. This zone prohibits all residential uses as well as any other uses deemed
hazardous to flight as determined by the Napa County Airport Land Use Commission.19

Present and Probable Need for Public Facilities and Services
Public facilities and services currently available or provided within the study area are
considered basic and include fire protection and law enforcement from the County.20 The
study area also receives basic services, directly and indirectly, from several countywide special
districts relating to vector control, soil conservation, parks and open-space, and flood
control. The basic level and scope of these present services in the study area appears
appropriate given the affected lands are undeveloped.
A full range of elevated public facilities and services are needed in the study area under both
the urban land use designations and zoning standards adopted by the County and American
Canyon. This includes, but is not limited to, an elevated level of community planning,
police, fire, water, sewer, storm drainage, and street lighting and maintenance. These
elevated services are expected to be needed in the timeframe of this review given two vested
projects are already tied to two of the affected assessor parcels. American Canyon is the
most logical multi-service provider for the study area based on service proximity.

Present Capacity of Public Facilities and Adequacy of Public Services
Information collected and analyzed in the municipal service review generally indicates
American Canyon presently has adequate capacities to extend a full range of public facilities
and services to the study area to accommodate its planned and probable urban uses under
the County and City’s land use policies. Specific and pertinent citywide capacity issues
identified in the municipal service review relevant to the study area’s potential development
that should be addressed at the time annexation is proposed include:
• Expansion of American Canyon’s water treatment and storage facilities to
independently accommodate current and future peak-day demands.
• Availability of potable water supplies to meet present and future service demands
during dry-year conditions.
• Improvements to traffic circulation to attain acceptable levels of services.
Existence of Social or Economic Communities of Interest
The study area’s social and economic interests are most strongly identified with American
Canyon. These interests have been primarily fostered through the community’s long-
standing expectation the study area would eventually become part of American Canyon
given its inclusion within the City’s original ULL. The Commission recently recognized and
strengthened these interests by including the affected lands in American Canyon’s
extraterritorial water and sewer service areas. The County has also recognized these interests
by agreeing to support the inclusion of the affected lands in the sphere as well as their
annexation to American Canyon. These interests also appear reciprocal given all three of the
current landowners within the study area have submitted letters of support to add their
properties to the sphere to facilitate future annexation and development.
Conclusion
Modifying American Canyon’s sphere to include the study area as well as the adjacent right-
of-way portion of State Highway 29 appears warranted given the preceding analysis.
Inclusion is consistent with the study area’s planned urban land uses under both the County
and American Canyon General Plans. Inclusion would be responsive to the probable need
for a full range of public services in which American Canyon is the most logical multi-service
provider. Inclusion would also recognize the study area’s existing and distinct social and
economic ties with American Canyon as well as support an agreement between the City and
County regarding the long-term development of the Napa County Airport area.
Furthermore, inclusion is consistent with the adopted policies of the Commission in
facilitating orderly municipal growth. This includes guiding future urban uses away from
County designated agricultural and open-space lands.

Study Area B
This study area comprises approximately 26 unincorporated acres located west of American
Canyon’s existing jurisdictional boundary and sphere near the intersection of Eucalyptus
Drive and Wetlands Edge Road. The study area also lies immediately west of an
unincorporated property commonly known as the “Eucalyptus Grove,” which is already in
the sphere. The study area represents a portion of a 113 acre assessor parcel purchased by
American Canyon in 1999. American Canyon refers to the study area as “Clarke Ranch
West” and added the affected lands to the ULL in 2008. The study area is considered for
inclusion into the sphere at the request of the American Canyon.

Present and Planned Uses, Including Agricultural and Open Space Lands
Existing Setting
The study area is generally undeveloped with no permanent structures. The far eastern
portion does include a small number of temporary structures and equipment associated with
the American Canyon 4-H Club, which houses small farm animals and poultry on site. The
study area was formerly part of a large commercial cattle ranch.
County Land Use Policies
The County designates the entire study area as Agriculture, Watershed and Open-Space and
contemplates a limited variety of non-urban uses ranging from agriculture to processing of
agricultural products. The designation also allows for a single-family residence. The
designation is supported by the County’s zoning standard of Agricultural Watershed for the
portion of the affected assessor parcel, which specifies a minimum lot requirement of 160
acres. The County General Plan was updated in 2008 to illustrate the entire study area as
part of American Canyon’s ULL. This illustration reflects the County’s expectation the
entire study area will be eventually developed for urban type uses within American Canyon.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
American Canyon Land Use Policies
American Canyon designates the entire study area as Open-Space with the intent the lands be
retained for open-space purposes, which includes passive recreation. American Canyon
recently prezoned the study area Open Space – Clarke West Ranch in conjunction with filing an
annexation proposal with the Commission. This prezoning prescribes a minimum lot
requirement of 10 acres.
Development Projects
American Canyon is currently in the process of completing a trail system connecting the City
to the Napa River that runs parallel along the southern and western perimeter of the study
area. American Canyon anticipates developing the study area into a passive public
recreational park. This anticipated use may also include building a public safety facility to
accommodate both a park ranger and fire station. The fire station, if built, would be used
and operated by ACFPD.
Additional Land Use Factors
The study area does not qualify as agricultural land under LAFCO law.21 It does, though,
qualify as open-space land given the study area’s designation under the County General Plan.
The affected assessor parcel is not subject to an agricultural contract. The study area also
lies within the Napa County Airport’s Compatibility Zones D and E. Zone D applies to
most of the study area and signals aircraft routinely fly-over at altitudes between 300 to 1,000
feet above ground. No residential or other uses deemed hazardous to flight by the Napa
County Airport Land Use Commission are allowed. Zone E applies to a small southeast
section of the study area and signifies aircraft commonly flyover at altitudes above 1,000 feet
in the course of landing or departing. Noise-sensitive outdoor uses are prohibited.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
There is no probable need for a full range of elevated public facilities and services within the
study area based on the non-urban land use designations and zoning standards adopted by
both the County and American Canyon. A limited number of elevated public services,
though, may be needed if the study area is annexed to American Canyon. In particular, this
would include providing elevated community planning and law enforcement to
accommodate and support the passive recreational use of the study area as contemplated by
American Canyon. Other elevated services, such as water and sewer, may also be needed
and defined when a specific project is proposed. American Canyon has indicated interest in
proceeding with a master plan to guide the recreational development of the study area in the
near future. If this development proceeds as contemplated, American Canyon is the most
logical service provider in terms of delivering coordinated community planning and law
enforcement as well as potentially extending water and sewer based on service proximity.

Information collected and analyzed in the municipal service review generally indicates
American Canyon presently has adequate capacities to extend a limited range of elevated
public facilities and services in the study area needed to accommodate its potential passive
recreational uses as contemplated by the City and allowed under its General Plan and Zoning
Ordinance. The municipal service review does not identify any specific and pertinent
capacity issues relative to American Canyon’s ability to accommodate this potential
recreational use in terms of extending community planning and law enforcement services.
This statement is predicated on presuming the demands would be relatively minimal; an
assumption that would be reassessed at the time annexation is considered.
Existence of Social or Economic Communities of Interest
The study area has established distinct social and economic interests with both the County
and American Canyon. The study area’s social and economic ties with the County were
established in 1968 and drawn from its designation under the County General Plan as
Agriculture, Watershed and Open Space. This designation carries significant local importance
given it underlies the County’s sustained effort to maintain agriculture as the region’s
primary land use as well as principal economic commodity. The designation also
underscores an important social tie with the general public given they have repeatedly
approved measures to protect all unincorporated agricultural lands as designated by the
County from urban uses unless specifically authorized by voters.
The study area’s social and economic interests with American Canyon were established in
1999 when the City purchased the affected lands with the intent of eventually developing the
site into a passive recreational park. American Canyon has strengthened these social and
economic ties by recently adding the study area to the ULL.
23
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
Conclusion
Modifying American Canyon’s sphere to include the study area does not appear warranted
given the preceding analysis. Inclusion would conflict with the study area’s present and
planned non-urban land uses under both the County and American Canyon General Plans,
which suggest a full range of public services are not needed. Inclusion would also dismiss
the tenured social and economic ties between the study area and the County. Additionally,
inclusion would be inconsistent with the adopted policy of the Commission to use a city
sphere to explicitly direct the location of urban development, which by practice has not been
defined to include public parks. Furthermore, there does not appear to be sufficient public
benefits outweighing the referenced policy considerations to support inclusion at this time.
As an alternative to expanding the sphere, the Commission may consider allowing American
Canyon to annex the study area under G.C. Section 56742. This statute allows LAFCOs to
annex non-contiguous lands owned and used by the affected city for municipal purposes
without consistency with their sphere. The statute also includes a “poison pill” to require
automatic detachment if the affected city ceases to the landowner. Proceeding under this
statute would allow American Canyon to coordinate elevated service provision within the
study area consistent with its contemplated uses without diminishing the Commission’s
assignment of the sphere as a demarcation of urban development. The Commission has
used this statute before in accommodating city annexations of public parks, the most recent
example involving Trancas Crossing to the City of Napa in February 2010.

County Land Use Policies
The County designates the entire study area as Cities, which memorializes its expectation the
affected lands are or shall be eventually incorporated. The County does not zone the
affected assessor parcels.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
American Canyon Land Use Policies
American Canyon designates the entire study area as Public. This designation contemplates a

American Canyon has also zoned the affected assessor parcels Public, which does not
prescribe a minimum lot requirement.
Development Projects
There are no current projects tied to the study area. American Canyon has indicated an
eventual interest in relocating the corporation yard to allow for the development of the dry
portion of the study area into a public park. It is not expected this potential project would
be initiated within the timeframe of this review.

Present and Probable Need for Public Facilities and Services
Nearly all of the study area is already entitled to receive a full range of elevated services from
American Canyon given the affected lands are incorporated. The entire study area is located
within ACFPD. The entire study area also receives basic services, directly and indirectly,
from several countywide special districts involving vector control, soil conservation, parks
and open-space, and flood control. The need for services is presently limited to basic public
safety since the affected lands are undeveloped for urban use.
There is a potential need for a full range of elevated public facilities and services within the
study area based on the quasi-urban land use designation and zoning standard adopted by
American Canyon. Future needs, however, are likely to be limited to community planning
and law enforcement to accommodate and support the potential use of the study area as a
passive recreational park as contemplated by American Canyon. Other elevated services,
such as water and sewer, may also be needed and defined when a specific project is
proposed. American Canyon has indicated no timetable for pursuing this development.
Nonetheless, if development does eventually proceed, American Canyon is the most logical

eventually developed. This statement is predicated on presuming the demands would be
relatively minimal; an assumption that would be reassessed at the time an annexation is
proposed for the 1.5 acre unincorporated portion of the study area.
Existence of Social or Economic Communities of Interest
The study area’s social and economic communities of interest are most strongly identified
with American Canyon. Economic interests were established at the time of American
Canyon’s incorporation when the City assumed ownership of the entire study area. Social
interests are drawn from the inclusion of the majority of the study area within American
Canyon’s jurisdictional boundary and expectation the site will eventually be developed into a
passive recreational park. The American Canyon General Plan supports these social and
economic ties by including the entire study area within the City’s ULL.
Conclusion
Modifying American Canyon’s sphere to include the study area does not appear warranted
given the preceding analysis. Inclusion would conflict with the lack of a current or probable
need for public services in the study area in the timeframe of this review. Additionally,
inclusion would be inconsistent with the adopted policy of the Commission to use a city
sphere to explicitly direct the location of urban development, which has not been defined by
practice to include public parks. There also does not appear to be sufficient public benefits

• Improvements to traffic circulation to attain acceptable levels of services.
Existence of Social or Economic Communities of Interest
The study area’s social and economic communities of interests are most strongly identified
with American Canyon. Social interests with American Canyon were formally established in
1997 when the study area was added to the original ULL marking a long-standing planning
assumption the affected lands would eventually become part of the City. Social interests
have been strengthened and expanded to include economic ties with the pending
development of the study area into a middle school to primarily serve the American Canyon
community. In addition, county voters affirmed their support in constructing the middle
school by approving the underlying funding bond measure in 2006. This support lessens the

drawn from its agricultural designation under the County General Plan.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
Conclusion
Modifying American Canyon’s sphere to include the study area appears warranted given the
preceding analysis. Inclusion is consistent with the pending use of the study area as a middle
school and supports the associated need for a full range of public services in which
American Canyon is the most logical multi-service provider. Inclusion would also recognize
the study area’s existing and distinct social and economic ties with American Canyon.
Notwithstanding the above statements, inclusion of the study area is arguably inconsistent
with the adopted policy of the Commission to exclude lands from city spheres designated
for agricultural use under the County General Plan for purposes of urban development.
This potential inconsistency, however, appears substantively muted because the middle
school would serve both incorporated and non-incorporated students, and therefore
supportive of both urban and non-urban development.

Study Area E
This study area comprises approximately 434 unincorporated acres located along the eastern
perimeter of American Canyon’s existing jurisdictional boundary and sphere. The study area
encompasses six entire assessor parcels and portions of five other assessor parcels. It also
includes adjacent portions of Newell Drive and Watson Lane and is bisected west-to-east by
a Pacific Gas & Electric tower transmission line. The study area was included in American
Canyon’s original ULL and is considered for inclusion into the sphere at the City’s request
and supported by the County as part of a May 2010 agreement.

Present and Planned Uses, Including Agricultural and Open Space Lands
Existing Setting
The study area is predominately undeveloped. The majority of the study area lies south of
Watson Lane and consists of native grassland along with three single-family residences. The
remaining portion of the study area lying north of Watson Lane consists of commercial
vineyards and two single-family residences.
County Land Use Policies
The County designates the entire study area as Agriculture, Watershed and Open-Space and
contemplates a limited variety of non-urban uses ranging from agriculture to processing of
agricultural products. The designation also allows for a single-family residence. The
designation is supported by the County’s zoning standard of Agricultural Watershed for the
affected assessor parcels, which specifies a minimum lot requirement of 160 acres. The
County General Plan was updated in 2008 to illustrate the entire study area as part of
American Canyon’s ULL. This illustration reflects the County’s expectation the entire study
area will be eventually developed for urban type uses within American Canyon.
American Canyon Land Use Policies
American Canyon divides the study area between two distinct designations and prezoning
standards. One-half of the study area lying along the eastern half is designated and
prezoned by American Canyon as Special Study, which specifies all uses and densities shall be
determined by a subsequent study. The remaining one-half of the study area is designated
and prezoned by American Canyon as Town Center. The Town Center assignments
contemplate a broad mix of urban uses ranging from residential to visitor-serving facilities.
Actual uses and densities, however, would be determined as part of a future specific plan.
Markedly, land designations and prezoning standards for the entire study area were adopted
by American Canyon in August 2008 in response to a citizens’ initiative certified to have
been signed by more than 10% of eligible voters.
Development Projects
There are no existing projects tied to the study area. However, as referenced above,
American Canyon has recently redesignated one-half of the study area lying immediately
adjacent to the City’s current sphere as Town Center.26 This designation for the affected lands
represents an expansion of a long-standing development concept tied to an approximate 100
acre area immediately south of the study area involving three assessor parcels collectively
referred to as the horseshoe. The most recent version of the town center concept was
prepared in May 2006 and involved developing the 100 acre area site south of the study area
into 600 to 650 residential units along with a mixture of commercial, retail, and public uses.
American Canyon has decided to expand the scope of the development concept to include
220 additional acres lying in the study area to allow, among other things, for the extension of
Newell Drive to Green Island Road to serve as an alternate and congestion-relieving route to
State Highway 29.
26 Prior to August 2008, the portion of the study area currently designated as Special Study was designated as Commercial
Recreation under the American Canyon General Plan. The portion of the study area currently designated as Town Center
was designated as Special Study.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
Additional Land Use Factors
A sizeable portion of the study area qualifies as agricultural land under LAFCO law given it
is either used for a commercial vineyard or subject to a Williamson Act contract.27 28 The
entire study area qualifies as open-space land based on its designation under the County
General Plan. Close to three-fourths of the study area also lies within the Napa County
Airport’s Compatibility Zones D and E. Zone D applies to approximately 55 acres located
in the far northern portion of the study area and signals aircraft routinely fly-over at altitudes
between 300 to 1,000 feet above ground. No residential uses as well as other uses deemed
hazardous to flight by the Napa County Airport Land Use Commission are allowed. Zone E
applies to approximately 287 acres lying within the middle section of the study area and
signifies aircraft routinely fly-over at altitudes above 1,000 feet in the course of landing or
departing. Any noise-sensitive outdoor uses are prohibited within this zone.

Present and Probable Need for Public Facilities and Services
Public facilities and services currently provided or available within the study area are
generally considered basic and include fire protection and law enforcement from the County.
The study area also receives basic services, directly and indirectly, from several countywide
special districts involving vector control, soil conservation, parks and open-space, and flood
control. Water service is provided by American Canyon to two of the affected assessor
parcels located along Watson Lane as a result of the City assuming ACCWD’s service
obligations at the time of incorporation.29 The present level and scope of services in the
study area appears appropriate relative to current land uses.
27 Over two-fifths of the study area’s soil (190 acres) qualifies as prime agricultural land under LAFCO law based on its
Class II rating by the United States Department of Agriculture’s Land Capability Index. Nearly all of the Class II soil is
located within the portion of the study area currently designated by American Canyon as Town Center.
28 There are currently three Williamson Act contracts involving five of the affected assessor parcels within the study area,
which cover 242 acres, of which 181.3 acres lies within the Town Center portion. These affected assessor parcels are
identified as 059-020-009, 059-020-008, 059-020-029, 059-030-004, and 059-020-032. The first three affected assessor
parcels listed total 181.3 acres and are owned by Jamcan, LLC and under the same contact, which is set to expire March
1, 2012. G.C. Section 56426.6 directs LAFCOs not to approve inclusion of lands under Williamson Act contracts into
city spheres unless it makes one of two findings: 1) inclusion would facilitate orderly growth and the public’s interest in
the jurisdictional change outweighs the public interest in continuing the contract or 2) inclusion will not adversely affect
the continuation of the contract.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
There is no need for a full range of elevated public facilities and services in the study area
based on the County’s non-urban land use designations and zoning standards. The probable
need for these types of facilities and services would only be triggered if the study area is
annexed to American Canyon. As noted, American Canyon has designated and prezoned
one-half of the study area for urban type development as part of its Town Center designation.
Elevated services required to support this potential urban use include, but are not limited to,
community planning, police, fire, water, sewer, storm drainage, and street lighting and
maintenance. American Canyon has expressed interest in submitting an annexation proposal
for this portion of the study area in the near future. It is unknown whether elevated public
services are needed in the Special Study portion given the lack of specificity regarding whether
the lands will be developed for urban or non-urban uses.

Probable Need for Public Facilities/Services ………………No …………..Yes (TC)

Need Based on Agency Land Use Designations
Present Capacity of Public Facilities and Adequacy of Public Services
Information collected and analyzed in the municipal service review is inconclusive with
respect to whether American Canyon currently has adequate capacities to provide a full
range of public facilities and services to the study area to accommodate potential urban uses.
This comment is drawn from the study area’s previous land use designations under the
American Canyon General Plan. As referenced, American Canyon redesignated the study
area from Commercial Recreation and Special Study to Special Study and Town Center, respectively,
in August 2008 in response to a citizens’ initiative. American Canyon’s facility plans,
however, have not been updated to address the service needs tied to the redesignation.
American Canyon has confirmed the City’s priority relative to the study area is to add only
the portion designated Town Center to the sphere to facilitate annexation and development
within the timeframe of this review. American Canyon also confirms it would be reasonable
to expect nearly four-fifths of the Town Center portion would be developed for residential
uses. American Canyon attests it expects this development to have a density pattern of six
housing units per acre consistent with intensification of the nearby Vintage Ranch
subdivision, which would result in up to 1,026 units.30 The remaining one-fifth portion lies
within Napa County Airport’s Zone D and is anticipated to be developed for various non-
residential uses. These expected land uses in the Town Center portion will generate
considerable service demands and strain the City’s present capacities.31 The collective
impacts of these demands have also not been analyzed by American Canyon relation to
existing and planned service commitments. The municipal service review attests, however,
American Canyon has a positive track record in using the discretionary review process to
expand public facility and service capacities to meet increasing demands as needed. This
includes entering into contracts to purchase additional water supplies if needed as well as
utilizing conditions of approval in financing capital improvements. The American Canyon
30 The housing unit estimate of 1,026 is based on the total number of acres eligible for residential use (190) minus a 10%
reduction to account for sidewalks and roads.
31 For example, the total annual demand on potable water supplies for the Town Center portion is estimated at 287 acre-feet
just for residential customers, which assumes each unit will consume 250 gallons per day. This estimated amount
represents 22% of American Canyon’s current available water supply capacity under normal conditions based on
information collected in the municipal service review.
35
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
General Plan also provides institutional guidance in aligning public services with demands.
This includes requiring regular reviews of police staffing levels and opportunities to increase
water supplies along with limiting sewer connections to comply with available treatment
capacity (6.7.2, 5.2.2, and 5.14.6). These policies coupled with practiced administrative
controls – including the use of developer agreements to secure infrastructure funding –
indicate American Canyon is reasonably capable of supporting urban uses within the Town
Center portion. Nevertheless, consistent with the municipal service review, specific and
pertinent citywide capacity issues to be addressed at the time annexation is proposed include:
• Expansion of American Canyon’s water treatment and storage facilities to
independently accommodate current and future peak-day demands.
• Availability of potable water supplies to meet present and future service demands
during dry-year conditions.
• Improvements to traffic circulation to attain acceptable levels of services.
Existence of Social or Economic Communities of Interest
The study area has established distinct social and economic interests with both the County
and American Canyon. The study area’s social and economic ties with the County were
established in 1968 and drawn from its designation under the County General Plan as
Agriculture, Watershed and Open Space. This designation carries significant local importance
given it underlies the County’s sustained effort to maintain agriculture as the region’s
primary land use as well as principal economic commodity. The designation also
underscores an important social tie with the general public given they have repeatedly
approved measures to protect all unincorporated agricultural lands as designated by the
County from urban uses unless specifically authorized by voters.
American Canyon’s social and economic ties to the study area were established in 1997 when
the City included the affected lands within its original ULL. The inclusion of the affected
lands in the ULL was recently reaffirmed and strengthened through a 2008 citizens’ initiative
and marks American Canyon’s expectation the lands be eventually development and served
by the City. (The citizen’s initiative also removed the Hess Vineyards from American
Canyon’s ULL and designated the Clarke Ranch West area for open space use, which helps
mitigate the potential loss of agricultural lands tied to the study area.) There are also distinct
social and economic interests between American Canyon and the Town Center portion.
These interests relate to American Canyon’s intention to annex and develop the subject
lands to facilitate three specific community goals: 1) extending Newell Drive; 2)
accommodating RHNA; and 3) providing for the development of a community anchor. The
County recognizes these interests and has provided its written support to add the Town Center
portion to the sphere and its subsequent annexation.
36
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
Conclusion
Modifying American Canyon’s sphere to include the portion of the study area designated
Special Study by the City does not appear appropriate given the preceding analysis. Adding
this portion is inconsistent with its present and planned non-urban land uses under the
County General Plan. Adding this portion may also be inconsistent with the American
Canyon General Plan given its does not specify whether urban or non-urban uses are
planned; a pertinent consideration given the Commission’s policy and practice to use spheres
as explicit guides to urban type development. The lack of specification regarding land uses
and densities for the Special Study portion under the American Canyon General Plan also
create uncertainty with respect to assessing the City’s present and future ability to provide an
appropriate level of municipal services. There also does not appear to be sufficient public
benefits outweighing the referenced policy considerations to support inclusion at this time.
Including the Town Center portion of the study area to American Canyon’s sphere also
presents policy challenges for the Commission based on the site’s composition of prime
agricultural lands and agricultural designation under the County General Plan. Local
conditions, however, suggest an exception to these policy considerations is warranted.
Adding the Town Center portion to the sphere provides American Canyon the most direct
opportunity to extend Newell Drive to provide a needed north-south alternative route to
State Highway 29 by working with developers in securing easements and funding. Adding
the Town Center portion will also help the County meet its RHNA as a result of its agreement
with American Canyon to receive housing credits from the City in exchange for supporting
the sphere addition and annexation of the affected lands.32 Markedly, this agreement will
help the County meet its State-mandated housing assignments without directing growth in
unincorporated areas that have limited public infrastructure. The Commission has expressed
support in making an exception to its referenced policy considerations given these two local
conditions –- extending Newell Drive and accommodating RHNA – in discussing the merits
of adding the Town Center portion at its April and May 2010 meetings.
32 This agreement commits American Canyon to transfer 368 housing units to the County over the next two planning cycles
(2014 and 2021) in exchange for the County’s support to add the affected lands to the sphere and their subsequent
annexation to the City. (The County’s housing unit assignment for the current cycle is 651.)

Study Area F
This study area comprises approximately 7.0 unincorporated acres located immediately
adjacent to the far northern perimeter of American Canyon’s existing jurisdictional boundary
and sphere. It encompasses two entire assessor parcels and an adjacent portion of State
Highway 29. The study area was included in American Canyon’s original ULL, but removed
as part of the 2008 revision. The study area is considered for inclusion into the sphere by
staff given the affected lands are surrounded nearly four-fifths by American Canyon’s ULL.

affected assessor parcels consists of a legal non-conforming single-family residence. The
adjacent right-of-way section of State Highway 29 includes four traffic lanes and a native
grass medium operated by the California Department of Transportation.

City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
County Land Use Policies
The County designates the entire study area as Industrial. This designation contemplates a
variety of urban non-residential uses ranging from manufacturing to office space. The
designation is supported by the County’s zoning standard of Industrial Park for all of the
affected assessor parcels, which specifies a minimum lot requirement of 5.0 acres. Specific
development and design standards for the study area are outlined in the County’s AIASP.
American Canyon Land Use Policies
American Canyon previously designated the study area as Industrial before deleting this
assignment in 2008 when the City removed the affected lands from its ULL in response to
the aforementioned citizens’ initiative.
Additional Land Use Factors
The study area does not qualify as agricultural or open-space lands under LAFCO law.33
None of the affected assessor parcels are under an agricultural contact. The study area does
lie within the Napa County Airport’s Compatibility Zone D, which marks the lands are
routinely overflown by aircraft ranging in altitude between 300 to 1,000 feet above ground.
This zone prohibits all residential and other uses deemed hazardous to flight as determined
by the Napa County Airport Land Use Commission.

Present and Probable Need for Public Facilities and Services
Public facilities and services currently provided or available within the study area are
generally considered basic. This includes law enforcement from the County as well as
services, directly and indirectly, from several countywide special districts relating to vector
control, soil conservation, parks and open-space, and flood control. The larger of the two
affected assessor parcels also receives fire protection from the County while the remaining
assessor parcel is located within ACFPD. No public water or sewer service is currently
provided. The present level and scope of services in the study area appears inadequate
relative to current urban land uses.
33 None of the study area comprises prime agricultural land as defined under LAFCO law.
39
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
A full range of elevated public facilities and services are needed in the study area under the
urban land use designation and zoning standard adopted by the County. This includes, but
is not limited to, an elevated level of community planning, police, fire, water, sewer, storm
drainage, and street lighting and maintenance. The need for these elevated public facilities
and services is already present and will be intensified upon the planned development of the
surrounding lands under the AIASP. American Canyon is the most logical multi-service
provider for the study area based on service proximity.
Category County of Napa American Canyon
Probable Need for Public Facilities/Services ………………Yes ………………N/A
Need Based on Agency Land Use Designations
Present Capacity of Public Facilities and Adequacy of Public Services
Information collected and analyzed in the municipal service review indicates American
Canyon has adequate capacities to extend a full range of public facilities and services to the
study area to accommodate its current and planned urban uses. Specific and pertinent
citywide capacity issues identified in the municipal service review relative to the study area’s
present and potential intensification under the AIASP that should be addressed at the time
annexation is proposed include:
• Expansion of American Canyon’s water treatment and storage facilities to
independently accommodate current and future peak-day demands.
• Availability of potable water supplies to meet present and future service demands
during dry-year conditions.
• Improvements to traffic circulation to attain acceptable levels of services.
Existence of Social or Economic Communities of Interest
The study area’s social and economic interests are most strongly identified with American
Canyon. These interests were fostered until recently through the standing expectation the
study area would eventually become part of American Canyon given its inclusion within the
City’s original ULL before it was removed in 2008. Notwithstanding the change to the ULL,
pertinent social and economic ties between the study area and American Canyon continue to
exist. This includes the inclusion of the study area within American Canyon’s Commission-
defined extraterritorial water and sewer service areas.
Conclusion
Modifying American Canyon’s sphere to include the study area appears warranted given the
preceding analysis. Inclusion is consistent with the present and planned urban land uses
under the County General Plan, which necessitates an elevated level of public facilities and
services in which American Canyon is best situated to provide. Inclusion also reflects and
strengthens existing social and economic interests between the study area and American
Canyon. Inclusion is also consistent with the adopted policies of the Commission. This
includes facilitating a more logical jurisdictional boundary line for American Canyon in
concert with the earlier recommendation to add Study Area A to the sphere and thereby
eliminate the potential future creation of an unincorporated pocket.34
34 The term “unincorporated pocket” is not defined. This term is intended to describe a portion of unincorporated land
substantially surrounded by a city without qualifying as an” island” under G.C. Section 56375.3.

VI. RECOMMENDATION
It is recommended the Commission update American Canyon’s sphere to include all lands
comprising Study Areas A, D, and F as well as the portion of Study Area E designated by the
City as Town Center. It is also recommended the Commission add a right-of-way portion of
State Highway 29 adjacent to Study Area A. The total size of the recommended additions to
the sphere is 543 acres. These additions support American Canyon’s orderly growth and
development in a manner generally consistent with the provision of the CKH and the
policies of the Commission. Special considerations are made with respect to supporting the
addition of the Town Center portion of Study Area E based on unique local conditions and
circumstances detailed on page 37 of this report.
Study Areas B, C, and the portion of E designated by American Canyon as Special Study are
not recommended for inclusion into the sphere given their additions are inconsistent with
Commission’s legislative directives as well as local policies and practices. Study Areas B and
C are not recommended for inclusion based on the Commission’s basic policy to use spheres
as explicit guides to urban development. This policy supports excluding the two study areas
since American Canyon contemplates developing both sites into public parks; a use that by
practice has not been considered urban by the Commission.35 The Special Study portion of
Study Area E is not recommended because the affected lands are designated for agricultural
use under the County General Plan. The American Canyon General Plan also does not
specify whether urban or non-urban uses are planned for the affected lands.
The following statements are based on information analyzed in this report and have been
prepared in support of the preceding recommendation pursuant to G.C. Section 56425:
1. Present and planned land uses in the sphere, including agricultural and open-
space lands.
Lands within American Canyon’s updated sphere are predominately developed for
urban uses or expected to be developed for urban uses within the next five years.
Agricultural and open-space lands in the updated sphere are relatively limited.
2. The present and probable need for public facilities and services in the sphere.
Lands within American Canyon’s updated sphere presently need an elevated level of
public services or are expected to need an elevated level of public services within the
next five years to accommodate and support urban uses. American Canyon is best
positioned to provide the necessary range of supporting urban services.
35 As stated on page 23 of this report, as an alternative to expanding the sphere, the Commission may consider allowing
American Canyon to annex Study Area B consistent with G.C. Section 56742. This statute allows LAFCOs to annex
non-contiguous lands owned and used by a city for municipal purposes without consistency with their sphere. The
statute also includes a “poison pill” to require automatic detachment if the city ceases to the landowner.
41
City of American Canyon: Sphere of Influence Review and Update LAFCO of Napa County
3. The present capacity of public facilities and adequacy of public services that
the agency provides or is authorized to provide.
The Commission’s recently completed municipal service review on the southeast
county region indicates American Canyon has generally established adequate
administrative, service, and financial capacities to accommodate present and planned
urban uses within the updated sphere.
4. The existence of any social or economic communities of interest in the sphere if
the commission determines that they are relevant to the agency.
Lands within the updated sphere have established social and economic
interdependencies with American Canyon distinct from neighboring unincorporated
areas. The update affirms and strengthens these established community ties.
