Santa Barbara committee reviews waterfront adaptation options to protect beaches, harbor from sea level rise

Summary
Adaptation and resilience staff presented a toolbox of short-, mid- and long-term measures — from beach nourishment and deployable floodproofing to revetments, groins and relocation — and said the plan will include technical analysis, funding proposals and public outreach with a draft plan due in 2027.
Melissa Hetrick, the city's adaptation and resilience manager, outlined options the city is evaluating to protect Santa Barbara's three-mile waterfront from increasing erosion and flooding, emphasizing a 30-year focus that balances beach access, recreation and habitat.
"The goal of this plan is to develop practical solutions to address coastal flooding and erosion for the next 30 years while enhancing beach access, recreation, boating, and habitat," Hetrick said during the Creeks Citizens Advisory Committee meeting.
Why it matters: The waterfront supports beaches, parks and the working harbor and contributes to regional tourism and the blue economy; Hetrick noted recent storms and erosion have already produced expensive cleanup and infrastructure damage and that planning now reduces long-term costs. She cited a January 2023 storm that required roughly $3,000,000 in cleanup.
What the city presented: Hetrick described a three-tiered approach: "quick wins" (low-cost, rapidly implementable actions), "core measures" (projects pursued after plan approval) and "future options" (large-scale changes requiring major trade-offs). Measures under consideration include:
- Seawalls and revetments: effective at protecting specific assets but can narrow beaches and complicate permitting. Hetrick cautioned they're best for immovable critical infrastructure such as harbor facilities.
- Beach nourishment, sand berms and dunes: can retain sandy beaches but require repeat maintenance and a reliable sand source.
- Groins, headlands and artificial reefs: trap sand and can widen beaches locally but risk downdrift erosion and can become politically contentious and expensive to maintain.
- Offshore reefs and wave screens: engineering options for shoreline and marina protection that require site-specific conditions and analysis.
- Relocation or removal of vulnerable development: a longer-term option to allow the shoreline to migrate inland and reduce risk to assets.
Hetrick said the team is emphasizing multi-benefit solutions where possible, for example an elevated, continuous separated walking and biking path that could also function as a backstop to flooding while improving public access.
Funding and schedule: Hetrick said the city has obtained more than $5 million across related resilience projects and that the waterfront project planning phase carries roughly $1,900,000 in funding from the California Coastal Commission and the California Coastal Conservancy. She said the plan will identify funding sources — including state coastal resiliency pools (the transcript references "Prop 4"), federal grants and potential local bonds — and will include cost estimates and a funding proposal. The schedule includes three outreach events (April 29 at the Faulkner Gallery, April 30 at the Maritime Museum and a virtual meeting on May 6) and a draft waterfront plan targeted for release in 2027, followed by a Local Coastal Program amendment and permitting with the California Coastal Commission.
Questions and concerns: Committee members pressed on funding for larger structural options and on habitat protections. Committee member Laurie Gaskin urged the project to prioritize habitat restoration in addition to recreation, saying the waterfront's dune and estuarine habitats should be "a central focus for Santa Barbara." Hetrick responded that habitat assessments and modeling of sediment movement are part of the background work and that the plan will look at how measures affect creek mouths and dune habitat.
Next steps: Staff will continue public outreach, perform the technical analyses, produce cost and benefit modeling for candidate measures and develop a draft plan for committee and public review in advance of the 2027 draft release.
