1.0 INTRODUCTION
ROLE AND RESPONSIBILITY OF LAFCO
The Cortese-Knox-Hertzberg Local Government Reorganization Act (Government Code Section
56000 et seq.) requires all Local Agency Formation Commissions (LAFCos), including the Solano
LAFCo, to conduct a municipal service reviews (MSR) prior to updating the spheres of influence
(SOI) of the various cities and special districts in the County (Government Code Section 56430).
The fundamental role of a LAFCo is to implement to CKH Act, providing for the logical, efficient,
and most appropriate formation of local municipalities, service areas, and special district. The
focus of this MSR is to provide LAFCo with all necessary and relevant information related to
Solano County Mosquito Abatement District (SCMAD) services.
PURPOSE OF THE MUNICIPAL SERVICE REVIEW
This MSR is intended to provide a comprehensive analysis of service provision by the SCMAD
within Solano County. This MSR will provide Solano LAFCo with an informational document and
make determinations in different areas of evaluation. The SCMAD’s boundary is coterminous to
both its Sphere of Influence and the County boundary; as such, this service review evaluates the
ability of the District to serve the entire County. The District’s boundary is shown in Figure 1.
This MSR evaluates the structure and operation of the District and discuss possible areas for
improvement or coordination. Key sources for this study were agency-specific information
gathered through research and surveys, as well as the Municipal Service Review Guidelines
published by the Governor’s Office of Planning and Research (OPR).
This report is divided up into six sections Infrastructure Needs and Deficiencies, Growth and
Population, Cost Avoidance and Facilities Sharing, Financing and Rate Restructuring,
Government Structure and Management Efficiencies, and Local Accountability.
INFRASTRUCTURE NEEDS AND DEFICIENCIES
This section analyzes whether sufficient infrastructure and capital are in place, and reviews
capabilities for accommodating future growth in service demands.
GROWTH AND POPULATION
This section reviews projected growth within the existing service boundaries of the District and
analyzes the District’s plans to accommodate future growth.
COST AVOIDANCE AND FACILITIES SHARING
This section evaluates factors affecting the financing of needed improvements, as well as
opportunities for the District to share facilities.
FINANCING AND RATE RESTRUCTURING
The District’s fiscal history is evaluated to determine viability and ability to meet service
demands. Rate structure is also examined as a means to eliminate unnecessary cost.

1.0 INTRODUCTION
GOVERNMENT STRUCTURE AND MANAGEMENT EFFICIENCIES
This section evaluates the ability of the District to meet its demands under its existing government
structure, and considers the overall managerial practices.
LOCAL ACCOUNTABILITY
This section examines how well the District makes its processes transparent to the public and
invites and encourages public participation.
OVERVIEW
SCMAD is an independent special district originally organized under the Mosquito Abatement
District Act of 1915 (Health and Safety Code §2000-2093). This Act was amended in 2002 and is
now referred to as the Mosquito Abatement and Vector Control District Law.
The District was founded in 1930 in order to control the pestiferous Ochlerotatus mosquitoes that
were being produced in the 184-square mile Suisun Marsh. The Solano County Mosquito
Abatement District is responsible for mosquito abatement throughout the incorporated and
unincorporated areas of Solano County, which covers 829 square miles.
The District is authorized by law to1:
a) Conduct surveillance programs and other appropriate studies of vectors and vector
borne diseases.
b) Take any and all necessary or proper actions to prevent the occurrence of vectors
and vector borne diseases.
c) Take any and all necessary or proper actions to abate or control vectors and vector
borne diseases.
THE MOSQUITOES OF SOLANO COUNTY
There are 21 mosquito species of concern in Solano County. Most of these species breed in the
habitats of the county characterized by standing water. Though all the species are capable of
creating nuisance, the main species of concern are the House mosquito (Culex pipiens) and
Encephalitis Mosquito (Culex tarsalis) because they lay eggs in stagnant water, wetlands and
marshlands. The county’s topography includes over 1,200 acres of tidal marshlands, ideal
habitat for the promulgation of mosquitoes.
Encephalitis Mosquito (Culex tarsalis)
These mosquitoes breed in rain pools, marshes, reservoirs, pools, rice fields, irrigation tailwaters,
ditches, and domestic sources. Although this species prefers clear, standing waters, it is
sometimes found in vegetation along streams and in polluted waters.
1The District is also permitted to take “any and all actions necessary for or incidental to the powers granted” by the governing act (d).

1.0 INTRODUCTION
This breed reaches maximum populations in the late summer, and in the hot weather they can
live for two or three weeks. During the cooler months, the females of this species may live for
several months.
As its common name suggests, this mosquito species is one of the most significant vectors of
Encephalitis in the state, carrying Western Equine Encephalitis (WEE), St. Louis Encephalitis (SLE),
and California Encephalitis. Also, this species was one of the most significant carriers of the West
Nile Virus as recently as 2004.
House mosquito (Culex pipiens)
These mosquitoes keep close ties with humans. Common breeding grounds for these
mosquitoes include standing waters such as street drainage, septic tanks and cesspools,
sewage, and backyard sources like unused swimming pools and stale-water ornamental ponds.
Like the Encephalitis mosquitoes, the house mosquitoes are at peak populations during the
summers and live for 2-3 weeks during hot months. This species is also a secondary vector of
Western Equine Encephalitis, St. Louis Encephalitis, and the West Nile Virus. Additionally, house
mosquitoes may also transmit the organisms causing bird malaria, fowl pox, and canine
heartworm.

2.0 EXECUTIVE SUMMARY
MUNICIPAL SERVICE REVIEW PROCESS
The Municipal Service Review (MSR) process is a comprehensive assessment of the ability of
government agencies to effectively and efficiently provide services to residents and users. The
form and content of the MSR is governed by requirements of the Cortese-Knox-Hertzberg Local
Government Reformation Act of 2000 (CKH Act) and the State of California’s LAFCo MSR
Guidelines (Guidelines), published in August 2003. This MSR considers the operations and
management of the mosquito abatement district within Solano County.
The MSR contains analysis and conclusions, referred to in this document as determinations,
regarding nine topic areas set forth in the CKH Act. These areas of analysis contain the essential
operational and management aspects of each district, and together constitute a complete
review of the ability of each provider to meet the service demands of the residents within their
boundaries. The nine topic areas have been combined into the following six topic headings for
analysis in this MSR:
1) Infrastructure Needs and Deficiencies
2) Growth
3) Financing and Rate Restructuring
4) Cost Avoidance and Facilities Sharing
5) Government Structure and Management Efficiencies
6) Local Accountability
An explanation of the specific operational and management aspects of each district
considered in each of these topic areas is provided below.
TOPIC AREAS OF ANALYSIS
The MSR considers the nine areas of analysis required by CKH. For ease of use and clarity in
reading, some of the topic areas have been combined in the body of the report. The following
topics of review are provided in the MSR:
1. INFRASTRUCTURE NEEDS AND SHARING OF FACILITIES
This section assesses the adequacy and quality of infrastructure at the District. Infrastructure
refers to the physical facilities in use by each district, including land, offices, equipment and
vehicles, and pesticide inventory. Occurrences of facilities sharing are listed and assessed for
efficiency, and existing facilities sharing arrangements are discussed.
2. GROWTH AND POPULATION
This section assesses the likely increase in service demand within the District. Changes in demand
for services can be based on a variety of factors, including future changes in demographics,
potential changes in land use, and the ability to track service demands and respond
accordingly.
3. COST AVOIDANCE AND FACILITIES SHARING
This section analyzes existing cost avoidance and facilities sharing measures currently being
utilized by the District to reduce the cost associated with service operations.

2.0 EXECUTIVE SUMMARY
4. FINANCING AND RATE RESTRUCTURING
This section analyzes the financial structure and viability of the District. Included in this analysis is
the consideration of local rates, revenue and expenditure sources, and service operations.
5. GOVERNMENT STRUCTURE AND MANAGEMENT EFFICIENCIES
This section compares existing District goals with existing operations and analyzes the existing
government structure for efficiency and effectiveness.
6. LOCAL ACCOUNTABILITY
This section includes an evaluation of the District’s compliance with public meeting and public
record laws, including the Ralph M. Brown Act.
SUMMARY OF DETERMINATIONS
Infrastructure Needs and Deficiencies
The District maintains an inventory of existing equipment and facilities. According to District
officials, existing infrastructure is sufficient to accommodate existing and projected service
needs.
Growth and Populations
District utilizes a database system to track service demands and respond accordingly. Ability to
meet future demand, involves consideration of future changes in demographics and potential
changes in land use; the capacity of the District to effectively address service demands is
dependent on its continued ability to adapt and redirect resources as needed. As urban and
suburban growth continue, the district reports it may be necessary to hire additional personnel
and is prepared to do so when necessary.
Cost Avoidance and Facilities Sharing
The District currently utilizes a variety of cost avoidance and facilities sharing opportunities
including: pooled insurance program, state and private re-imbursement agreements,
membership in the Mosquito and Vector Control Association of California, and facilities sharing.
The District appears to utilize a sufficient range of cost avoidance and facilities sharing
opportunities.
Financing and Rate Restructuring
Auditors reports and budgets were reviewed; the District appears to be in good financial
standing.
Government Structure and Management Efficiencies
The District works to meet its existing mission statement and internal goals. Based on its principal
act, the District could expand its services to include vectors other than mosquitoes without
activating a new power or getting prior approval by LAFCO. The overall management structure

SUMMARY OF SERVICE PROVISION
The Solano County Mosquito Abatement District provides comprehensive control services of all
mosquitoes which may bring disease or harassment to humans or domestic animals. Service
needs necessary to fulfill this service is reviewed and updated continuously based on the
District’s extensive surveillance program. Surveillance includes regular review of all known
locations of mosquito production during breeding season, independent checks of all areas for
new sources, and responses to service requests made by residents of the County. Based on this
information, the District develops a response, mitigation, and education program designed to
reduce mosquito populations and to educate property owners and residents about risk
reduction.
The program for providing comprehensive control services is broad and includes a variety of
overlapping programs and practices to eliminate mosquitoes. The following programs and
practices are implemented as appropriate and necessary to address mosquito breeding within
Solano County:
• Deployment to and treatment on properties upon request by a property owner or
resident.
• Routine inspection and treatment of known mosquito breeding sources every 7-10
days during breeding season.
• Aerial spraying of State-owned lands within the Suisun Marsh, private duck clubs, and
other areas, as appropriate.
• Hosting annual workshops for duck club owners to educate them about Best
Management Practices for reducing mosquito populations.
• Provides mosquito fish free of charge for use in mosquito-breeding waters.
• Monitoring and trapping of mosquitoes throughout the County.
• Testing of larval and adult populations of mosquitoes for diseases with the potential to
harm humans and domestic animals.
• Biological and chemical treatments of waters and mosquito grounds to control
populations and reduce future breeding opportunities.
• Provides recommendations to landowners on physical modifications to their land in
order to reduce mosquito breeding.
• Summation of findings and distribution of mosquito statistics to the California
Department of Health Services.
• Education of private property owners regarding mosquito breeding and risks of
mosquitoes to human and animal health.
• Collection of dead birds to be tested at other facilities for a variety of diseases,
including several forms of encephalitis.
• Testing of dead birds for West Nile virus using district facilities

The implementation of these programs and practices is intensive and requires significant
resources, including allocation of staff hours in the field for testing and monitoring, use of
vehicles, testing and monitoring equipment, testing and storage facilities, significant quantities of
pesticides, insecticides, and other chemicals to kill mosquito larvae and adults, and protective
gear for District personnel. Mosquito fish and guppies are bred and grown on site for use and
distribution, requiring ponds and supporting resources to ensure adequate growth and
harvesting ability.
In addition, the District is required to maintain and operate the District consistent with State laws
governing special districts, including applicable provisions of the Health and Safety Code,
Government Code, and other statutes.
INFRASTRUCTURE NEEDS AND DEFICIENCIES
The District operates from its administrative office at 2950 Industrial Court in Fairfield. District
facilities include administrative offices plus an internet room, map room, file room, Board room,
conference room, and Laboratory.

Additionally, the District owns other smaller equipment for service and maintenance, as well as
analysis equipment for the biological lab contained at the District offices. The District maintains
a full listing of all equipment and facilities.
According to the District Manager, the existing infrastructure is sufficient to accommodate both
present demand and anticipated future demands. Equipment and facilities of the District
appear sufficient to provide necessary services. All infrastructure and equipment, including
vehicles, generators, and facilities, are owned by the District. There are no outstanding issues
related to the needs and deficiencies of infrastructure with the District.
DETERMINATIONS
1) The Solano County Mosquito Abatement District provides mosquito control services
for the citizens of Solano County. The District has sufficient infrastructure and
resources to provide effective abatement services within the boundaries of the
District, both at present and into the future.

GROWTH AND POPULATION
Assessing future service demands, and the District’s ability to meet that demand, involves
consideration of future changes in demographics, potential changes in land use, and the ability
to track service demands and respond accordingly.
POPULATION GROWTH
Solano County is slated to be a growth leader among the nine Bay Area counties in all
categories during the next twenty years, with a 32% increase in population, a 37% increase in
jobs, a 33% increase in the number of households, and 31% increase in the number of employed
residents.

LAND USE
In 1984 Solano County adopted the “Solano County Orderly Growth Initiative,” directing all
growth into urbanized and incorporated areas. The initiative was reaffirmed in 1994 and
protects the designations of specific non-urban lands through 2010. The initiative also puts
restrictions on certain residential lands and agricultural lands, guaranteeing growth will not
extend and require urban services in these areas.
SERVICE DEMANDS
SCMAD service demands relating to mosquito control are based on a combination of factors,
including seasonal conditions, breeding habits, and the presence of stagnant water. Mosquitoes
are a year round problem and the District maintains constant surveillance to provide treatment
when necessary. The overall greatest peak in demand occurs during mid-June to mid-October,
with some areas having peak demands outside the normal mid-June to mid-October period.
Outside of the greatest peak demand period, District personnel spend the rest of the year
treating other major problem areas, treating the Suisun marsh, performing maintenance, and
getting equipment ready for peak demand.
To track service demands, the SCMAD implemented a database data collection system in 2005.
The database includes the name and address of requestor, dates of activity (prior, request,
action), technician visits, treatment type, and acres treated, and hours spent on the service
request.
According to the District records, in an average month, the District receives approximately 110
service requests, which results in 100 technician visits to properties. On average, 160 acres are
treated on 20 different properties. An average of 20 hours were spent addressing the needs of
each property requiring treatment.
In addition to responding daily to service requests made by Solano County residents, Control
technicians routinely inspect known mosquito sources within the SCMAD on a 7 to 10-day cycle
and independently check areas for new sources of mosquitoes. Samples are identified and
findings are sent to the California Department of Health Services.

3.0 SOLANO COUNTY MOSQUITO ABATEMENT DISTRICT
As population increases, and growth occurs within Solano County, service demands will
increase. Urban areas provide breeding habitats for mosquitoes (stagnant water), and
treatment becomes more difficult and costly, as treatment needs occur more on individual
private properties. District officials note that at monthly safety meetings, new developments are
discussed, and the need for hiring more personnel/obtaining more equipment is discussed.
Expansion of services is facilitated by increases in revenues due to increases in property tax
income from new development.
DETERMINATIONS:
1) Service demands for the Solano County Mosquito Abatement District are guided
primarily by seasonal, environmental, and land use activities in the county. Current
mechanisms are sufficient to allow the District the flexibility necessary to meet service
demands. The capacity of the District to effectively address future service demands
is dependent on its continued ability to adapt and redirect resources as needed.
2) As service demands continue, the District has the financial and administrative
resources necessary to hire additional personnel and is prepared to do so when
warranted.
COST AVOIDANCE AND FACILITIES SHARING
The District utilizes a variety of cost avoidance and facilities sharing measures in its operations.
The District maintains a pooled insurance program through the California Special District’s
Association for comprehensive general liability, property damage, and worker’s compensation.
Other cost avoidance activities include the use of the “Argo” vehicle, which is an amphibious
off-road All Terrain Vehicle (ATV), and allows a singular employee to cover more terrain than in
the past.
Reimbursements by state and private sources allow the District to recover costs for providing
higher levels of service to properties with persistent mosquito problems. The District is reimbursed
by the Department of Fish and Game (DFG) for aerial spraying on the state-owned lands in the
Suisun Marsh. Additionally, the District is reimbursed 50% of the costs of aerial pesticides on
private duck club properties through an agreement with the Suisun Resource Conservation
District and private duck club owners.
The District is a member of the Mosquito and Vector Control Association of California. This
organization is comprised of 56 public agencies and provides its members with a number of
valuable services, including cost avoidance opportunities relating to training services and
publication materials. Other notable services offered by this organization include serving as a
legislative advocate for statewide vector control and abatement issues and facilitating the
exchange of service information between member agencies
SCMAD participates in facilities sharing. The Suisun Resource Conservation District holds annual
workshops for duck club owners at the SCMAD facilities, and a major topic at these workshops is
Best Management Practices (BMPs) for reducing mosquito populations.
DETERMINATIONS
1) The District appears to utilize a sufficient range of cost avoidance and facilities
sharing opportunities.

FINANCING AND RATE RESTRUCTURING
Annual auditors reports and financial statements from fiscal year (FY) 2004-05 were reviewed to
determine the fiscal status of the District.
For most services provided by the District, fees are not charged to private homeowners for
services rendered; sources of revenue for the District include air spraying re-imbursements,
interest, and other sources including mosquito fish sales. For properties requiring regular or
frequent treatment for mosquito breeding, fees are levied upon the property owner for services
provided. The District’s primary funding source is property tax revenue; $.50 per $1,000 of
property tax revenue collected by the County is distributed to the District. Revenues for FY 2004-
05 totaled $1,676,864.
The District’s primary source of expenditures is salaries and benefits, which totaled $839,392 in FY
2004-05. Other sources of expenditures included operations (insecticides, materials/supplies, and
equipment maintenance), administrations (including professional services, memberships, board
expenses, and travel), building and equipment purchases, and depreciation. Total expenditures
for FY 2004-05 totaled $1,390,694.
In fiscal year 2005, The District’s actual revenues exceed operating expenses by more than
$285,000. Budgeted expenses exceeded actual expenses by $622,756. According to District
personnel, the District generally projects high expenses in anticipation of potential costs that
would be associated with West Nile, were it to become a problem during that fiscal year.

The District has experienced significant changes in its funding during its history. The passage of
the Educational Revenue Augmentation Fund (ERAF) affected this and all special districts by
changing the allocation of tax revenues to provide additional support to school districts
Statewide. The passage of the ERAF resulted in a loss of approximately 50 percent of the
District’s operating revenue. As a result, the District experienced a significant reduction in
staffing levels and service capabilities. The District has the flexibility to change its staffing levels
and service provision to account for yearly changes in revenue, and has shown an ability by the
District to meet its service demands in times of financial uncertainty.
DETERMINATIONS:
1) Services provided by the Solano County Mosquito Abatement District are funded
from property taxes. This revenue stream ensures that each property owner pays a
proportionate share of the District’s operational expenses and supports the equitable
distribution of vector control services in Solano County. The District generally does not
charge user fees or fees for service; however charges to private ducks clubs, state
property, and fees to repeat customers augment income levels.
2) The District is in good financial standing, as revenues are currently exceeding
expenditures. The FY 2004-05 audit noted that the District was in full compliance with
the law.
GOVERNMENT STRUCTURE AND MANAGEMENT EFFICIENCIES
GOVERNMENT STRUCTURE
The government structure of a District refers to its legal structure under California law, its enabling
legislation, and the powers granted to the District by its charter. The Solano County Mosquito
Abatement District was formed under the Mosquito Abatement District Act of 1915, codified in
the Health and Safety Code as Section 2000-2093. The District is an independent special district,
indicating its autonomy from other government entities.
The Health and Safety Code currently permit few types of government entities to perform
mosquito abatement services. Cities and counties, as well as mosquito abatement and vector
control districts, have the authority to provide these services. In review of the provision of this
service across Solano County, the need to ensure that service is provided comprehensively is
essential, thus the entity providing service must be able to serve the entire County. The only
other service provider legally permitted and structurally able to provide the service at this scale
is the County of Solano.
If the District is unable to continue the provision of this service, there are several options available
to transfer the service from the SCMAD to the County. The two most appropriate options are (1)
the District could be dissolved with the County then assuming service, or (2) the District could be
reorganized as a subsidiary district to the County. In either case, the change in government
structure would be warranted only if the current provision of service was unacceptable, or future
conditions would lead to the inability of the District to continue an adequate level of service.
Eliminating the District or reforming the District under the County would involve a significant
expenditure of time and resources to process the change, and would not result in an
improvement in service levels or a greater cost efficiency in the provision of service. Based on
the analysis of the SCMAD contained in this MSR, there is no current justification for altering the
government structure of the District or changing the service provider.

MANAGEMENT EFFICIENCIES
A District Manager is hired by the appointed Board of Trustees to mange the operation of the
District. The District Manager oversees eight full-time employees including a Biologist, Supervisor,
Secretary-Bookkeeper, and five Control Technicians. Each technician is assigned one particular
zone within the service boundary of the District. The Department of Health Services mandates
certification of all technicians.
SCMAD’s jurisdictional boundary is coterminous with its Sphere of Influence and includes all lands
within the contiguous 829 square miles of Solano County. SCMAD does not overlap any other
jurisdictions providing the same or similar services, and it does not serve any land outside its
boundaries.
As reported by the District’s manager, the District’s mission statement is:
[T]o control all mosquitoes which may bring disease or harassment to humans and
domestic animals. This is accomplished by using the most effective and economical
measures that result in the least possible damage to non-target organisms or to other
elements of the environment.1
To meet its mission, the District conducts larval and adult mosquito control and monitoring and
trapping, although most activity in the district occurs during the spring and summer months
when mosquito growth and activity is at its peak.
District goals include killing mosquitoes in their larval stage, before they have wings. The main
species of concern are the Culex pipiens and Culex tarsalis because they lay eggs in stagnant
water, wetlands and marshlands.
SCMAD’s mosquito abatement programs include controlling both larval and adult populations
through physical control and environmental modifications as well as biological and chemical
controls.
PHYSICAL CONTROL
The District’s primary tool for reducing mosquito populations is through source reduction and
environmental management strategies. The most successful long-term solutions for mosquito
abatement are physically controlling or modifying mosquito habits to help revoke or lessen man-
made or natural breeding ground.
BIOLOGICAL CONTROL
SCMAD uses biological control for both short- and long-term abatement wherever possible. This
method involves stocking stagnant water sources with mosquito fish, which feed on larvae.
Mosquito fish do not work in salty or shallow waters or polluted water. No other biological control
methods are currently employed by the district.
CHEMICAL CONTROL
The District only uses chemical control as a temporary, short-term strategy for managing both
larvae and adult species. If the District determines the other control methods would be

ineffective in controlling a particular mosquito population in a particular habitat, pesticides may
be applied by hand, machine, or aircraft.
In addition to operations, District management and employees receive regular training in
methods of treatment, new products and practices, and related changes in the field. The
District Manager attends the four meetings of the Mosquito and Vector Control Association of
California (MVCAC) held each year, and updates its practices and policies according to
available information and resources. Employee training is conducted as needed and required
under State and federal laws.
DETERMINATIONS:
1) The Solano County Mosquito Abatement District is empowered under California
Heath and Safety Code to provide a broad range of services relating to the control
of vectors and vector-borne diseases. Based on its principal act, the District could
expand its services to include vectors other than mosquitoes2 without activating a
new power or getting prior approval by LAFCO.
2) The overall management structure of the District is sufficient to account for necessary
services and maintain operations in an efficient and effective manner. The District
works actively to meet its internal goals.
LOCAL ACCOUNTABILITY
The District has an eight-member Board of Trustees that serves as its decision-making body. The
Board consists of appointees from the seven City Councils in Solano and one member
appointed by the County Board of Supervisors.
