Subject:Adopt the Contra Costa County Hazard Mitigation Plan Update for Flood Control and Fire Protection
Districts, Countywide. Proj #7505-6F8227, CP #11-11
FISCAL IMPACT:
Approval of the County’s Hazard Mitigation Plan does not impose any requirement on
the Flood Control District or the Fire Protection District, which would result in a fiscal
impact. On the other hand, failure to adopt the updated Hazard Mitigation Plan may
preclude the Districts from obtaining FEMA Disaster Mitigation funds or Disaster
Recovery funds in the future. (100% Flood Control District Funds)
BACKGROUND:
On June 28, 2011, the Contra Costa Board of Supervisors conducted a properly noticed
public hearing, and adopted both an amendment to the General Plan and the CCCHMP.
This plan was prepared to cover the County, and 35 additional agencies, special districts,
and cities. The original intent was for this Board to approve the plan not only for Contra
Costa County, but also for the Flood Control District and for the Fire Protection District.
Unfortunately, due to staff oversight, the Board’s June 28, 2011, action covered only
Contra Costa County, not the Board-governed, dependent special districts that had
participated in the creation of (and are also covered by) the CCCHMP. Today’s Board
action corrects this omission and provides specific Board approval of the CCCHMP to
clarify that the CCCHMP also covers the Flood Control District and the Fire Protection
District.
The Federal Disaster Act of 2000 requires local governments to adopt a comprehensive
Hazard Mitigation Plan (HMP) to receive federal funding after a disaster. By law, an
HMP must describe the type, location, and extent of all natural hazards that can affect a
jurisdiction; describe the jurisdiction’s vulnerability to these hazards; include a mitigation
strategy that provides the jurisdiction’s blueprint for reducing the potential losses; and
contain a planned maintenance process. The Disaster Mitigation Act of 2000 strongly
encourages state and local authorities to work together on predisaster planning, and it
promotes “sustainable hazard mitigation,” which includes sound management of natural
resources, local economic and social resiliency, and the recognition that hazards and
mitigation must be understood in the largest possible social and economic context.
Hazard Mitigation Plan Adoption
County staff from the Public Works Department and the Office of Emergency Services
secured a FEMA planning grant to prepare a comprehensive and integrated
multi-jurisdictional HMP focused on Contra Costa County.
Once the FEMA planning grant was awarded in Fall 2007, key staff from the Department
of Public Works and the Office of Emergency Services assembled a planning partnership
of 36 Contra Costa agencies, including the County, cities, and special districts. The
partnership collaborated in the development of the update to the HMP in a five-phase
planning process over a 24-month period. It resulted in a two-volume document that
provides a comprehensive blueprint for hazard risk reduction in Contra Costa County for
the next five years. Attached for the Board of Supervisors consideration under Exhibit
One are excerpts from the two volume plan, including the Executive Summary and the
Flood Control District’s and the Fire Protection District’s annexes to the plan.
The ensuing planning process developed a new HMP for the County and its planning
partners from scratch, using lessons learned from a previous Association of Bay Area
Governments (ABAG) regional planning effort. While this HMP is an update for many of
the planning partners, it is the initial plan for others, such as the Flood Control and Fire
Protection Districts. The updated HMP differs from the ABAG hazard mitigation plan, as
follows:
• The updated HMP has been totally restructured as a Countywide regional plan, focusing
only on Contra Costa County. The risk assessment is not a subset of a larger regional
effort. It is isolated to Contra Costa County and focuses on hazards of concern for the
County.
• The updated HMP was expanded to include special purpose districts as planning
partners.
• The risk assessment has been formatted to better support future grant applications by
providing risk and vulnerability information that will directly support the measurement of
“cost-effectiveness” required under FEMA mitigation grant programs.
• Newly available data and tools provide for a more detailed and accurate risk
assessment. The ABAG regional hazard mitigation plan did not use tools such as
FEMA’s Hazards U.S. Multi-Hazard (HAZUS-MH) computer model or new data, such as
FEMA’s Countywide Digital Flood Insurance Rate Maps (DFIRMs).
• The updated HMP gave the County and its planning partners an opportunity to engage
local citizens and gauge their perception of risk and support for risk reduction through
mitigation.
An Initial Study/Negative Declaration was prepared pursuant to the California
Environmental Quality Act (CEQA) Guidelines. The Initial Study/Negative Declaration
describes the proposed project; it identifies, analyzes, and evaluates the potential impacts,
which may result from the HMP adoption; and no significant environmental effects were
found to result from the HMP adoption. The Initial Study/Negative Declaration was
circulated for a 30-day comment period, but no comments were received.
CONSEQUENCE OF NEGATIVE ACTION:
If not approved, the result would be inability to apply for and receive FEMA Disaster
Mitigation Funds and/or disqualification from receiving state disaster assistance funding.
CHILDREN'S IMPACT STATEMENT:
Not applicable.

22.2 JURISDICTION PROFILE
Contra Costa County Fire Protection District (Con Fire) provides fire prevention, suppression, and
emergency medical response for advanced and basic life support to nine cities and much of the
unincorporated area in the central and western portions of Contra Costa County. Con Fire was formed on
December 29, 1964 as a county-dependent district governed by the Contra Costa County Board of
Supervisors. The principal act that governs the District is the Fire Protection District Law of 1987
(California). Since its inception, Con Fire has consolidated with several other fire districts with the most
recent significant consolidation occurring in 1994. There were some subsequent detachments of portions
of Con Fire between 1997 and 2001, but since 2001 Con Fire’s service area has remained the same.
The following is a summary of key information about the jurisdiction:
•Population Served—598,051
•Land Area Served—Approximately 300 square miles
•Value of Area Served—Total assessed property value (FY 09/10) for the area served by Con
Fire is $67,647,071,600
•Land Area Owned—Approximately 48 acres (35 separate locations throughout Contra
Costa County)
•List of Critical Infrastructure/Equipment Owned by the Jurisdiction (the apparatus are
located at 30 different sites (fire stations) all of which are in natural hazard risk zones):
– 28 Type 1 engines
– 2 Type 2 engines
– 17 Type 3 engines
– 1 Type 4 engine
– 6 Quints
– 4 specialty rescue vehicles
– 1 rescue boat

•Total Value of Critical Infrastructure/Equipment—The total replacement cost value of
critical infrastructure and equipment owned by the jurisdiction is $29,240,000.
•List of Critical Facilities Owned by the Jurisdiction: See Table 22-1
•Total Value of Critical Facilities—The total value of critical facilities owned by the
jurisdiction is $52,327,800
•Current and Anticipated Service Trends—The fire district has experienced a 28 percent
increase in call volume since 2000, and this trend is expected to continue. Approximately 75
percent of the calls are for Emergency Medical Services (EMS). According to the Association
of Bay Area Governments (ABAG) the projected growth rate from 2008 to 2030 is 16
percent. The largest area (approximately 5,000 acres) of future growth will be in the central
portion of the county that was once part of the Concord Naval Weapons Station (CNWS).
The planned development of the CNWS site will result in a significant increase in population
density that will require an expansion of fire and emergency medical service resources to
accommodate the increase in call volume. Other planned developments in the eastern portion
of the fire district will necessitate additional fire and emergency medical resources to handle
population growth, as well as mitigate emergency response times.

22.7 HAZARD MITIGATION ACTION PLAN AND EVALUATION OF
RECOMMENDED INITIATIVES
Table 22-5 lists the initiatives that make up the jurisdiction’s hazard mitigation plan. Table 22-6 identifies
the priority for each initiative. Table 22-7 summarizes the mitigation initiatives by hazard of concern and
the six mitigation types.
22.8 ADDITIONAL COMMENTS
Con Fire is currently (FY 09/10) experiencing a drastic decrease in our property tax revenues. Since
property taxes account for approximately 85 percent of the District’s total revenue, thus the fire district is
faced with unprecedented budgetary challenges. It is anticipated that property tax revenues will not
recover and/or increase until FY 11/12. Therefore, implementation of hazard mitigation initiatives will be
subject to these extreme budgetary constraints.

32.2 JURISDICTION PROFILE
The Contra Costa Flood Control and Water Conservation District (District) is a dependent Special
District, first formed by an act of the State legislature in 1951. Its governing document is the Contra Costa
County Flood Control and Water Conservation District Act, last amended in 1992, which grants the
District various powers such as the ability to acquire and hold property; sue and be sued; conserve, store
and import water; control flood waters; issue bonds; levy taxes and assessments and use eminent domain.
The governing board of the District is the County’s five-member Board of Supervisors, which are elected
to four year terms. Each Supervisor represents a specific area of the County.
The District plans, constructs and maintains major flood protection infrastructure to reduce flooding risk.
The District’s jurisdiction encompasses all of Contra Costa County, including all nineteen incorporated
cities.
The District’s funding comes from a combination of ad-valorem taxes and fees paid by developers upon
creation of impervious surfaces. The District has approximately 20 staff, and relies on other specialists
from the Contra Costa County Public Works Department, with whom they share office space.
The following is a summary of key information about the jurisdiction:
•Population Served—1,060,435 residents as of January 1, 2009 (California Department of
Finance)
•Land Area Served—720 square miles
•Value of Area Served—The estimated value of the area served by the jurisdiction is
$174,133,000
•Land Area Owned—2,600 acres in fee, 1450 acre easement
•List of Critical Infrastructure/Equipment Owned by the Jurisdiction:
– 21 Drop Structures $46 million
– 89,650 feet of Concrete Channels $225 million
– 4 Dams $112 million
– 34,600 feet of Levees $35 million
February 14, 2012 Contra Costa County Board of Supervisors 417
Contra Costa County Hazard Mitigation Plan; Volume 2—Planning Partner Annexes…
32-2
– 12 Detention Basins $10 million
– Various Specialized equipment and trucks $1 million
•Total Value of Critical Infrastructure/Equipment—The total replacement cost value of
critical infrastructure and equipment owned by the jurisdiction is $383 million.
•List of Critical Facilities Owned by the Jurisdiction:
– CC Rich Building, Glacier Drive (District main office)
– Waterbird Maintenance Yard
•Total Value of Critical Facilities—The total value of critical facilities owned by the
jurisdiction is $10 million.
•Current and Anticipated Service Trends—The District’s service area is broken up into
three distinct regions of the County: west, central and east. The west and central portions of
the county are nearing their full development potential. Service demands are expected to
increase in these areas not because of added population, but primarily because of increased
customer demands for more ecologically sensitive flood protection, including potential
removal of concrete lining of channels and restoration of the resulting streams. Other factors
expected to increase demands for District services include the effect of global climate change
on low-lying areas, increased regulatory requirements on operation and maintenance of
existing facilities, and new clean water requirements on trash and other pollutants.
• The eastern portion of the District’s service area includes the fast-growing cities of Pittsburg,
Antioch, Oakley and Brentwood. Here, population growth means significantly increased
runoff and customer demands for improved levels of protection as agricultural lands are
converted to residential and commercial uses. Additionally, this eastern portion of the County
has the same issues noted for central and west portions noted above.
The area served includes all of Contra Costa County, including all nineteen incorporated cities. The

32-3
• The District has a business plan, an expenditure policy and a Capital Improvement Plan. The
expenditure policy sets the following order of priorities: system preservation, public safety,
and system expansion. This relates to hazard mitigation plan because it emphasizes repair and
rehabilitation of existing facilities to ensure they remain able to reduce flood risk and
minimize the risk of dam failure.
32.6 CLASSIFICATION IN HAZARD MITIGATION PROGRAMS
The jurisdiction’s classifications under various hazard mitigation programs are presented in Table 32-3.
32.7 HAZARD MITIGATION ACTION PLAN AND EVALUATION OF
RECOMMENDED INITIATIVES
Table 32-4 lists the initiatives that make up the jurisdiction’s hazard mitigation plan. Table 32-5 identifies
the priority for each initiative. Table 32-6 summarizes the mitigation initiatives by hazard of concern and
the six mitigation types.
32.8 FUTURE NEEDS TO BETTER UNDERSTAND
RISK/VULNERABILITY
The District has number of areas where lack of information limits smart planning efforts:
• East county floodplain maps are approximate - have good topography, but need a detailed
two dimensional floodplain analysis.
• Kellogg Creek FIRM does not correctly show the effect of the Los Vaqueros Reservoir. Need
to revisit this analysis and update.
• District reservoirs are nearing 50 years old, and will likely need rehabilitation including a
seismic vulnerability analysis. Needed to keep probability of dam failure low.
• District capital improvement plan (CIP) needs to be updated.
• District funding sources are insufficient to meet new or expected clean water mandates, such
as trash and mercury total maximum daily loads (TMDL).
• Some District levees no longer enjoy FEMA accreditation, and the District lacks the
resources to study and potentially improve these levees be re-accredited.

Project Title, Description, Common Name (if any) and Location: Contra Costa County Hazard Mitigation Plan
Update Project, Countywide, Project No. WO 8227, SCH or CP#11-11.
The project consists of the Contra Costa County Hazard Mitigation Plan Update (HMP). The plan is a countywide
plan among planning partners which include the County, cities, and special districts. Natural hazards assessed
were dam failure, drought, earthquake, flood, landslide, severe weather, and wildland fire. Cities and special
districts within the County were given the opportunity to participate and obtain coverage under the HMP. Hazard
mitigation initiatives were determined by each planning partner for their jurisdictions and identified in an Action Plan
Matrix. Additional supporting information was also included in planning partner application packages. Linkage
procedures are included in the plan for those entities wishing to obtain coverage under the HMP at a later date.
The HMP is strictly a planning document that identifies potential hazards and specifies initiatives that will reduce or
eliminate long-term risks to human life, property and the environment from natural disasters. Additionally, the HMP
sets a framework for procurement of disaster related funding, and initiates cooperation between districts. Adoption
of the HMP does not approve or mandate construction of projects, or methods of construction. Implementation of
any initiative that has the potential to cause an effect on the environment will undergo project specific CEQA review.
The project was approved on .
