CENTRAL SAN BOARD OF DIRECTORS POSITION PAPER DRAFT MEETING DATE: FEBRUARY 13, 2018 SUBJECT: REVI EW DRAFT POSITION PAPER FOR CENTRAL CONTRA COSTA SANITARY DISTRICT (CENTRAL SAN) TO ADOPT RESOLUTION NO. 2018- -ADOPTING VOLUME 1 AND PORTIONS OF VOLUME 2 OF THE CONTRA COSTA COUNTY HAZARD MITIGATION PLAN (CCCHMP) SUBMITTED BY: INITIATING DEPARTMENT: SHARI DEUTSCH, RISK MANAGEMENT ADMINISTRATION DEPARTMENT- RISK ADMINISTRATOR MANAGEMENT REVIEWED BY: PHILIP R. LEIBER, DIRECTOR OF FINANCE AND ADMINISTRATION ANN SASAKI, DEPUTY GENERAL MANAGER ISSUE Central Contra Costa Sanitary District (Central San) has partnered with Contra Costa County, and other public entities within the County, to update its multi jurisdictional Hazard Mitigation Plan. The Board must adopt the updated Plan before the Federal Emergency Management Agency(FEMA)will grant final approval to Central San for eligibility to receive future potential funding from the Hazard Mitigation Grant Program and the Pre-Disaster Mitigation Program. BACKGROUND I n November 2016, a coalition of Contra Costa County cities and special districts embarked on a planning process to prepare for and lessen the impacts of specified natural hazards by updating the Contra Costa County Hazard Mitigation Plan (CCCHMP). Responding to federal mandates in the Disaster Mitigation Act of 2000 (Public Law 106-390), the partnership was formed to pool resources and to create a uniform hazard mitigation strategy that can be consistently applied to the defined planning area and used to ensure eligibility for specified grant funding success. This effort is a comprehensive update to the 2012 CCCHMP. The 35-member coalition of partners involved in this update includes unincorporated Contra Costa County, 14 city and town governments and 20 special districts. The planning area for this update was defined as the Contra Costa County Operational Area. The result of this coordinated planning effort will be a FEMA and California Office of Emergency Services (CaIOES) approved multi-jurisdictional, multi-hazard mitigation plan. February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 3 of 74 Page 2 of 22 Central San staff served on a 13-member Hazard Mitigation Steering Committee composed of representative stakeholders. This committee formed early in the planning process to guide the development of the CCCHMP. In addition, citizens were asked to contribute by sharing local knowledge of their individual area's vulnerability to natural hazards based on past occurrences. Public involvement was solicited via a comprehensive public outreach campaign that included two rounds of public meetings, web-based information, a questionnaire, and multiple social media updates. The updated CCCHMP addresses the following hazards of concern: 1. Dam failure 2. Drought 3. Earthquake 4. Flood 5. Landslide 6. Severe weather 7. Tsunami 8. Wildfire Climate change is incorporated as a summary assessment of current and anticipated impacts for each identified hazard of concern. With the exception of dam failure, the CCCHMP does not provide a full risk assessment of human-caused hazards. However, brief, qualitative discussions of the following hazards of interest are included: terrorism, cyber threats, hazardous materials release, pipeline and tank failure and airline incidents. Additionally, the CCCHMP has been aligned with the goals, objectives and priorities of the State's multi-hazard mitigation plan. All participating jurisdictions have been responsible for assisting in the development of the hazard and vulnerability assessments and the mitigation action strategies for their respective organizations. The CCCHMP presents the accumulated information in a unified framework to ensure a comprehensive and coordinated plan covering the entire Contra Costa County planning area. Each jurisdiction has been responsible for the review and approval of their individual sections of the plan. Upon adoption of Volume 1, and the referenced sections of Volume 2 of the CCCHMP, and subsequent approval by CalOES and FEMA, Central San will maintain its eligibility to apply for grants under the Hazard Mitigation Grant Program and the Pre-Disaster Mitigation Program (see Attachment 3 for additional program information). The grant funds can be used to implement the long-term hazard mitigation measures specified within Central San's annex of the updated plan before and after a major disaster declaration. The CCCHMP is considered a living document such that, as awareness of additional hazards develop, and new strategies and projects are conceived to offset or prevent losses arising from natural disasters, the CCCHMP will be evaluated and revised regularly. Staff has evaluated this action and concluded it is exempt from the California Environmental Quality Act (CEQA) under Central San's CEQA Guidelines Section 15262, since this plan allows for further planning and feasibility studies for possible future actions which Central San has not approved, adopted or funded, and the outcome of these tasks will not have a legally binding effect on later activities. Central San will conduct an environmental evaluation of any capital project that is proposed in the future as a result the tasks authorized herein to determine the need for any additional CEQ documentation. The resolution (see Attachment 1) specifies that the Board is only adopting sections that apply to all participating agencies, and Central San's own annex(see Attachment 2). The full text of these sections are available for review in the Secretary of the District's office. February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 4 of 74 Page 3 of 22 ALTERNATIVES/CONSIDERATIONS The alternative is to not adopt the updated CCCHMP, and become ineligible to apply for grants under the Hazard Mitigation Grant Program and the Pre-Disaster Mitigation Program. FINANCIAL IMPACTS Upon final approval from FEMA, Central San will maintain its eligibility to apply for grants under the Hazard Mitigation Grant Program and the Pre-Disaster Mitigation Program. COMMITTEE RECOMMENDATION This item was reviewed by the Administration Committee on February 13, 2018, which recommended that the Board adopt the updated Plan.

This statute is referred to as the Sanitary District Act of 1923. CCCSD is a Special District created in 1946 to provide wastewater collection and treatment to the residents and businesses in the central area of Contra Costa County. Over time,the District's service area has expanded to incorporate areas of new development and those areas where sewers have been constructed to replace septic systems. The District is governed by a five-member elected Board of Directors. The Board of Directors assumes responsibility for the adoption of this plan,while the General Manager will oversee its implementation. The District currently serves approximately 463,000 residents and 3,000 businesses in 10 cities within the central county area. The District's headquarters and treatment plant are based in Martinez. The treatment plant is capable of treating 54 million gallons of wastewater per day and has handled up to 240 million gallons per day in wet weather. The District's collections system operation is based in Walnut Creek which allows crews to respond to emergencies within the service area in less than one hour. The collections system operation is responsible for the cleaning, maintenance and repair of the District's 1,500 miles of underground pipeline and its 18 pumping stations. The District also operates a household hazardous waste collection facility,provides recycled water to customers for irrigation and other industrial uses, and manages a source control program with enforcement authority to prevent pollution from entering area waters. Funding comes primarily through annual sewer service charges, ad valorem taxes,and sewer connection permit fees. However,the District has occasionally issued revenue bonds to finance capital improvements. According to County and City planners,the District's service area(see Figure 18-1)is comprised of high value land. As a result, development trends indicate higher residential densities and more compact commercial developments. Population growth will come from lot splits,infill development, construction of in-law units and a TETRA TECH 18-1 February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 10 of 74 Page 9 of 22 Contra Costa County Hazard Mitigation Plan;Volume 2—Planning Partner Annexes rise in multi-generational households.As a result,the District is focused on increasing the capacity of its current collections and treatment systems rather than on construction of new pipe segments.

Plan integration is the incorporation of this information into other relevant planning mechanisms, such as general planning and capital facilities planning. It includes the integration of natural hazard information and mitigation policies,principles and actions into local planning mechanisms and vice versa. Additionally,plan integration is achieved though the involvement of key staff and community officials in collaboratively planning for hazard mitigation. 18.4.1 Existing Integration In the performance period since adoption of the previous hazard mitigation plan,the Central Contra Costa Sanitary District made progress on integrating hazard mitigation goals,objectives and actions into other planning initiatives. The following plans and programs currently integrate components of the hazard mitigation strategy: • Capital Improvement Plan—July 2016 edition; 10 year plan outlining intended capital improvements, focused on risk reduction and environmentally sustainable operations • Capital Improvement Budget—Annual budget reflecting the highest priority items from the Capital Improvement Plan,includes operational optimization and reducing environmental impacts • Sewer System Management Plan—State regulatory requirement to ensure efforts are made to reduce risks to public health,property and the environment • NPDES Permit—State regulatory requirement,renewed 4/1/17,issued by the Regional Water Quality Control Board, specifies criteria for discharging treated wastewater • CCCSD Emergency Operations Plan—September 2016, SEMS and NIMS compliant plan,reviewed annually and updated as needed • Treatment Plant Seismic Vulnerability Assessment of Selected Facilities—December 2009,used as a planning tool for subsequent and ongoing capital needs,risk reduction and operational resilience. Resources listed in Section 18.11 were used to provide information on hazard events and local capabilities within the jurisdiction. 18.4.2 Opportunities for Future Integration As this hazard mitigation plan is implemented,the Central Contra Costa Sanitary District will use information from the plan as the best available science and data on natural hazards. The capability assessment presented in this annex identifies codes,plans and programs that provide opportunities for integration. The area-wide and local action plans developed for this hazard mitigation plan include actions related to plan integration, and progress on these actions will be reported through the progress reporting process described in Volume 1.New opportunities for integration also will be identified as part of the annual progress report. The capability assessment identified the following plans and programs that do not currently integrate goals or recommendations of the hazard mitigation plan but provide opportunities to do so in the future: • Comprehensive Wastewater Master Plan-20 year plan projecting long term capital needs,considers risk reduction, operational optimization, environmentally sustainable operations and regulatory compliance. • Physical and Natural Hazard Vulnerability AssessmentA more detailed assessment of sites with recommendation to reduce exposure and maintain or return to normal operations after a hazard event. • Capital Improvement Plan—Effective July 2017, 10 year plan outlining intended capital improvements, focused on risk reduction and environmentally sustainable operations. • CCCSD Continuity of Operations Plan–Currently under development 18-6 TETRA TECH February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 15 of 74 Page 14 of 22 18.Central Contra Costa Sanitary District 18.5 JURISDICTION-SPECIFIC NATURAL HAZARD EVENT HISTORY Table 18-6 lists past occurrences of natural hazards for which specific damage was recorded in the Central Contra Costa Sanitary District.

HAZARD MITIGATION GRANT PROGRAM (HMGP) What is the Hazard Mitigation Grant Program? HMGP is authorized by Section 404 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, as amended (the Stafford Act), Title 42, United States Code (U.S.C.)5170c. The key purpose of HMGP is to provide the opportunity to take critical mitigation measures to reduce future loss of life and property during the reconstruction process following a disaster. HMGP is available, when authorized under a Presidential major disaster declaration, in the Tribe or areas of the State requested by the Governor.The amount of HMGP funding available is based upon the estimated total Federal assistance provided by FEMA for disaster recovery under the Presidential major disaster declaration. Who is eligible to apply? Hazard Mitigation Grant Program funding is only available to applicants that reside within a Presidentially declared disaster area. Eligible applicants are • State and local governments • Indian tribes or other tribal organizations • Certain non-profit organizations What types of projects can be funded by the HMGP? HMGP funds may be used to fund projects that will reduce or eliminate the losses from future disasters. Projects must provide a long-term solution to a problem, for example, elevation of a home to reduce the risk of flood damages as opposed to buying sandbags and pumps to fight the flood. In addition, a project's potential savings must be more than the cost of implementing the project. Funds may be used to protect either public or private property or to purchase property that has been subjected to, or is in danger of, repetitive damage. Examples of projects include, but are not limited to: • Acquisition of real property for willing sellers and demolition or relocation of buildings to convert the property to open space use • Retrofitting structures and facilities to minimize damages from high winds, earthquake,flood, wildfire, or other natural hazards • Elevation of flood prone structures • Safe room construction • Development and initial implementation of vegetative management programs • Minor flood control projects that do not duplicate the flood prevention activities of other Federal agencies • Localized flood control projects, such as certain ring levees and floodwall systems, that are designed specifically to protect critical facilities February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 22 of 74 Page 21 of 22 • Post-disaster building code related activities that support building code officials during the reconstruction process What are the minimum project criteria? There are five issues you must consider when determining the eligibility of a proposed project. • Does your project conform to your State's Hazard Mitigation Plan? • Does your project provide a beneficial impact on the disaster area i.e. the State? • Does your application meet the environmental requirements? • Does your project solve a problem independently? • Is your project cost-effective? II. PRE-DISASTER MITIGATION GRANT PROGRAM (PDM) What is the Pre-Disaster Mitigation competitive grant program? The Pre-Disaster Mitigation (PDM) competitive grant program provides funds to State, Tribal, and local governments for pre-disaster mitigation planning and projects primarily addressing natural hazards. Cost-effective pre-disaster mitigation activities reduce risk to life and property from natural hazard events before a natural disaster strikes, thus reducing overall risks to the population and structures, while also reducing reliance on funding from actual disaster declarations. Funds will be awarded on a competitive basis to successful applicants for mitigation planning and project applications intended to make local governments more resistant to the pacts of future natural disasters. Who can apply for a PDM competitive grant? Eligible PDM competitive grant applicants include state and territorial emergency management agencies, or a similar office of the State, District of Columbia, U.S. Virgin Islands, Commonwealth of Puerto Rico, Guam, American Samoa, Commonwealth of the Northern Mariana Islands, and Federally-recognized Indian Tribal governments. • Eligible Sub-applicants include State agencies; Federally-recognized Indian Tribal governments; and local governments (including State recognized Indian Tribal governments and Alaska native villages). • Applicants can apply for PDM competitive grant funds directly to FEMA, while Sub-applicants must apply for funds through an eligible Applicant. • Private non-profit organizations are not eligible to apply for PDM but may ask the appropriate local government to submit an application for the proposed activity on their behalf. What are eligible PDM projects? Multi-hazard mitigation projects must primarily focus on natural hazards but also may address hazards caused by non-natural forces. Funding is restricted to a maximum of $3M Federal share per project. The following are eligible mitigation projects: • Acquisition or relocation of hazard-prone property for conversion to open space in perpetuity; February 13, 2018 Regular ADMIN Committee Meeting Agenda Packet- Page 23 of 74 Page 22 of 22 • Structural and non-structural retrofitting of existing buildings and facilities (including designs and feasibility studies when included as part of the construction project) for wildfire, seismic, wind or flood hazards (e.g., elevation, flood proofing, storm shutters, hurricane clips); • Minor structural hazard control or protection projects that may include vegetation management, stormwater management (e.g., culverts, floodgates, retention basins), or shoreline/landslide stabilization; and, • Localized flood control projects, such as certain ring levees and floodwall systems,that are designed specifically to protect critical facilities and that do not constitute a section of a larger flood control system. Mitigation Project Requirements Projects should be technically feasible and ready to implement. Engineering designs for projects must be included in the application to allow FEMA to assess the effectiveness and feasibility of the proposed project. The project cost estimate should complement the engineering design, including all anticipated costs. FEMA has several formats that it uses in cost estimating for projects. Additionally, other Federal agencies' approaches to project cost estimating can be used as long as the method provides for a complete and accurate estimate. FEMA can provide technical assistance on engineering documentation and cost estimation. Mitigation projects also must meet the following criteria: • Be cost-effective and substantially reduce the risk of future damage, hardship, loss, or suffering resulting from a major disaster, consistent with 44 CFR 206.434(c)(5) and related guidance, and have a Benefit-Cost Analysis that results in a benefit-cost ratio of 1.0 or greater; • Be in conformance with the current FEMA-approved State hazard mitigation plan; • Solve a problem independently or constitute a functional portion of a solution where there is assurance that the project as a whole will be completed, consistent with 44 CFR 206.434(b)(4); • Be in conformance with 44 CFR Part 9, Floodplain Management and Protection of Wetlands, and 44 CFR Part 10, consistent with 44 CFR 206.434(c)(3); • Not duplicate benefits available from another source for the same purpose, including assistance that another Federal agency or program has the primary authority to provide (see Section VII.C. Duplication of Benefits and Programs); • Be located in a community that is participating in the NFIP if they have been identified through the NFIP as having a Special Flood Hazard Area (a FHBM or FIRM has been issued). In addition, the community must not be on probation, suspended or withdrawn from the NFIP; and, • Meet the requirements of Federal, State, and local laws.
