Climate Resiliency – IRWM Plan
8 April 2020
Very High Priority VulnerabilitiesWater Supply: Decrease in groundwater supplyWater Demand: Lack of groundwater storage to buffer drought Water Quality: Poor water quality in surface waters • Water Quality: Increase in treatment needs and costs*• Water Quality: Increased constituent concentrations*Water Quality: Poor water quality in Groundwater**• Water Quality: Increase in treatment needs and costs*• Water Quality: Increased constituent concentrations*Water Quality: Increased erosion and sedimentationWater Supply: Sensitivity due to higher drought potential
The tables and information were derived from an IRWM survey to the Santa Barbara County Cooperating Partners. The questions were related to Regional Water Management Strategies and climate related priorities in each of the watersheds and countywide.
Prioritized Climate Change Vulnerabilities
Based on discussion in the April 29, 2018 meeting a “very high” prioritization has been added with the following vulnerabilities(vulnerabilities moved to the very high category contain strike through in Table 2 on the next slide):
Table 1: Very High Priority
*Water Quality: Increase in treatment needs and costs and Water Quality: Increased constituent concentrations were moved to subsets of other vulnerabilities**Water Quality: Poor water quality in Groundwater is a newly added vulnerability

CITY OF SANTA BARBARA DRAFT SEA-LEVEL RISE ADAPTATION PLAN
SantaBarbaraCA.gov
Sea-Level Rise Planning: Why Now?• Sea-level rise expected to accelerate.
• General Plan and Coastal Plan direct preparation of a sea-level rise plan.
• Sea-level rise analysis required for coastal, NPDES, and other permitting.
• 2019 Coastal Land Use Plan includes interim policies; long-term policies needed.
2
SantaBarbaraCA.gov
Adaptation Plan Process• Vulnerability Assessment (2018)
- Diagnoses the problem- Considers what would happen if no action
was taken
• Adaptation Plan (2020)- Provides framework for planning- Analyzes adaptation options- Considers economic and fiscal impacts- Identifies near-term priorities- Considers triggers for mid-term and long-term

Bluff erosion hazards are expected to reach Cliff Drive and Shoreline Drive by 2100.
Bluffs will be exposed to more extreme waves more often, and erosion rates are expected to increase (40% higher by 2060 and 140% higher by 2100).

Adaptation Planning Approach• Sea-Level Rise Adaptation Plan
- Presents a phased approach to adaptation planning based on monitoring of changing conditions and trigger-based actions
- Recommends specific near-term (ten-year) actions - Proposes structure for decision making in mid- and long-term
• Five-year Implementation Plan - Further prioritizes near-term actions and Identifies costs, funding,
timelines, and required resources
• Shoreline Monitoring Program• Re-evaluation of overall adaptation plan every ten years13
SantaBarbaraCA.gov
Adaptation Options• Protection of development in place
through measures such as seawalls, groins, tide gates, and beach nourishment
• Accommodation of development in place through measures such as elevation or modifications of structures
• Retreat through measures such as relocation of structures and development limitations
SantaBarbaraCA.gov
Low-Lying and Waterfront Areas• Recommended Near-Term Actions
- Introduce additional beach nourishment, beach berms, or dunes
- Raise Harbor breakwater and groins- Redesign Laguna Tide Gate- Relocate or flood proof sewer
mains and utilities under beach
15
SantaBarbaraCA.gov
Low-Lying and Waterfront Areas• Recommended Near-Term Actions
- Revise floodplain regulations for development south of Highway 101
- Continue existing requirements south of Cabrillo Blvd. that factor in increased erosion and flooding from SLR
- Initiate studies of mid- and long-term options for wastewater, stormwater, and water systems
16
SantaBarbaraCA.gov
Low-Lying and Waterfront Areas• Decisions in the Mid- and Long-Term
- Consider flood protection measures such as:• Seawalls or levees along the Waterfront• Levees or floodwalls along lower portions of major creeks• Groundwater dewatering wells and stormwater pumps• Relocation and flood proofing of critical facilities
17
SantaBarbaraCA.gov
Other City-Wide Recommendations• Amend City policies, procedures, and adjust staffing • Amend the Local Coastal Program, General Plan, Hazard
Mitigation Plan, Municipal Code, Capital Improvement Program
• Consider hazard disclosures and risk indemnifications• Continue Sea-Level Rise Subcommittee and Interdepartmental
Staff Team• Regional, state, and federal agency coordination• Closely follow emerging information on adaptation options,
case law, and sea-level rise science.18

Sea Level Rise
2019: Sea Level Rise Vulnerability Assessment and Adaptation Project – Final Assesses vulnerabilities and provides adaptation strategies• Key vulnerabilities found: loss of land, affordable
housing, impacts to key transit corridors (railroad, US 101), environmentally sensitive habitat impacted, loss of coastal access and beaches.
2020: Interim adaptation policies presented to Planning Commission• Included options for new/redevelopment and zone
boundaries for wave run-up studies, site specific coastal hazards studies, or special conditions relating to coastal hazards
General Plan/Local Coastal Plan
Using the findings of the SLR Vulnerability Assessment and Adaption Project, policies are being drafted for inclusion in the General Plan update.• Draft policies currently under review by Coastal
Commission• First public draft expected to be released later this
year for comment
For more information: http://www.carpinteria.ca.us/communitydev/GeneralPlanUpdate.shtml
Dune & Shoreline Management RFP
City of Carpinteria released a request for proposal for Coastal Engineering Services for a Dune and Shoreline Management Plan in February 2020
Key objectives:• Build on existing sea level rise adaptation planning
efforts• Coastal hazards modeling• Develop conceptual design for living shoreline• Develop a plan for long-term shoreline
management
City is currently in negotiations with a consulting firm following interviews.
