Hazard Mitigation Planning Working Group
• 18 Municipalities • Fire Districts • Water Districts • San Diego Foundation/ICLEI • Federal, State and local agencies
with mitigation responsibilities
…priorities and commitments will be adopted locally so local general-purpose governments need to be actively involved
Adding Climate Change
• Discussed at initial WG Meeting • Developed group consensus • Briefed Unified Disaster Council • ICLEI/San Diego Foundation
provided two Climate Change Workshops to illustrate current and potential future impacts
• Stakeholder Workshop scheduled for next month
Impacts of Climate Change
• Higher temperatures & shorter rainy season – Drier soils & vegetation = increased fire
risk. Longer, less predicable fire seasons
– Regions water sources may shrink 20% or more by 2050. Water demand expected to increase by 29%
Impacts of Climate Change
• Heat waves, wildfires – Direct health exposure risk
• Elderly, children, low-income residents, chronically ill
– Exacerbates air pollution – Increased demand for electricity leading
to potential brown-outs/black-outs
Impacts of Climate Change
• Sea Level Rise: – Increasingly frequent extreme sea levels – Storm related flooding will occur more
often and reach farther inland – Increased beach and cliff erosion – Most vulnerable:
• Stormwater, wastewater, shoreline parks, commercial facilities, ecosystems
Mitigation Strategy
• Main components: – Goals – General guidelines for what we
want to achieve (broad policy-type statements)
– Objectives – Focuses on how to achieve goals
– Actions – Specific projects and activities designed to help achieve the goals
– Action Plan – Describes how mitigation actions will be implemented
Types of Mitigation Actions Used in San Diego
• Structural solutions – Retrofitting
unreinforced masonry structures
– Flood control projects – Improved drainage – Building materials (i.e.,
Class A Roofs, etc.) – Seismic upgrades – Water storage upgrades – Upgrade access for first
responder equipment
Types of Mitigation Actions Used in San Diego
• Regulatory solutions – Vegetation Management
• Weed abatement regulations
– Building/Fire Codes – Fire Safety inspections – Climate Action Plan – Floodplain, Coastal Bluff Overlay
Zones – Water Master Plans – Upgrade water delivery systems
Types of Mitigation Actions Used in San Diego

• Non-structural solutions – Acquire land for open space
development – Manage open space preserves to
minimize fuel load – Becoming “Tsunami Ready” or
“Storm Ready” – Public/Private partnerships
San Diego County Hazard Mitigation Plan Hazard Mitigation Planning Process
San Diego County Hazard Mitigation
Work Group
Individual Municipalities
UDC
Final Draft Plan
Unified Disaster Council
Adoption at Local Level
San Diego County Board of Supervisors, City
Councils and Governing Boards
Risk Assessment is completed with input from municipalities.
The Work Group members supply input from municipalities to finalize the plan.
The final plan is forwarded to State OES/FEMA for review. Once conditional approval is received, plan is then adopted by all participating jurisdictions.
San Diego County Hazard Mitigation
Work Group Draft Plan
Individual Municipalities
San Diego County
• Board of Supervisors/City Councils – Initiate, authorize and support the hazard
mitigation planning process – Adopt the Hazard Mitigation Plan
• Unified Disaster Council – Policy Making
• Office of Emergency Services (OES) – Project management – Community liaison – Meeting coordination and facilitation – Active project support and involvement
Individual Jurisdictions
“Ground-truth” information and priorities from Hazard Mitigation Work Group including: ü Providing more detailed information for
potential loss estimation; and ü Identifying, recommending and approving
specific mitigation action items for their communities
