The Carpinteria Salt Marsh — a portion of the remaining coastal wetlands in Santa Barbara County — has become a legal battleground over a proposed house at 501 Sand Point Road.
The house, elevated above an environmentally sensitive habitat area (ESHA) has been contested over environmental concerns. Friends of the Carpinteria Salt Marsh say construction will threaten hundreds of species that call the marsh their habitat, as well as the vital flooding control function of the marsh.
“It affects everybody,” said Marc Chytilo, lawyer for the Friends of the Carpinteria Salt Marsh. “This isn’t just a situation where someone who lives next door is affected by it, it’s a matter of ecological significance.”
On Wednesday, Judge Thomas P. Anderle of the Superior Court of Santa Barbara postponed a court hearing between the Friends of the Carpinteria Salt Marsh (an organization that aimed to challenge the environmental legality of the project) and the California Coastal Commission.
In the meantime, the developers claim that renderings and plans for the house have been blown out of proportion, and exclude the fact that the project will include restoration efforts for the valuable sand dune habitat by removing invasive ice-plants.
“We have every bit of commitment to making this the best sand dune restoration ever in Santa Barbara County,” said Mark Massara, attorney for the developer, Sanddew LLC.
A legal history
In May of 2025, the California Coastal Commission ruled 6-3 to approve the project with 15 conditions, including a 25-foot ESHA buffer and “bird-safe” window glass. A month later, Friends of the Marsh filed a petition with the Superior Court of California, aiming to challenge the Coastal Commission’s approval.
In approving the developers’ application, Chytilo said the Coastal Commission made a procedural error. The development violates Coastal Act guidelines, one being that only developments that are coastal-dependent (like a pier) can build on ESHAs. The parcel intrudes into the ESHA, and single-family houses are not coastal-dependent, Chytilo said.
However, the Coastal Commission found an exception. The Fifth Amendment states that the government may only seize private property for “public use” and must pay the owner “just compensation.” This is called a “taking.” To avoid an unconstitutional taking, the Commission approved the project despite the ESHA, Chytilo said.
Massara, the attorney for the project, had a different story.
He said the heart of the case rests within an altercation between neighbors of 501 Sand Point and the developers. After the Coastal Commission pushed the proposed development further into the existing residential neighborhood, neighbors were concerned about space and privacy.
“This case has become a mountain out of a molehill,” Massara said. “We just wish the neighbor would clean up their invasive ice-plants.”
The developers worked with “A-list biologists and landscape architects” to design a restoration plan for the nearby habitat. Massara said the plan was a motivator of the Coastal Commission’s approval.
Still, local environmentalists warn that construction will trigger catastrophe on the entire Salt Marsh ecosystem.
Environmental concern
The entire Salt Marsh spans 230 acres. About 120 of these acres are owned by the University of California, which utilizes the area for research and teaching, and protects the reserve. UCSB professor Andrew Brooks, the director of the reserve, approves research applications and educates people on the Salt Marsh.
Even though the land ownership is divided, the Salt Marsh operates as one unit with hundreds of intertwined ecological systems, Brooks said.
“The plants and animals in the Salt Marsh don’t recognize property lines on a county assessor map,” Brooks said. “They move freely from that portion (the reserve) to all parts of the marsh.”
Over 200 bird species call the Salt Marsh home, such as snowy plovers, ospreys and a western burrowing owl. Migrating birds also use it as a rest-stop, meaning that changes to the habitat could disrupt migration patterns. Increased light would also disrupt behavioral patterns for nocturnal species, leading to higher predation rates on birds at night, Brooks added.
But the Salt Marsh doesn’t just serve birds and fish. When extreme weather leads to flooding, Carpinteria’s wetlands serve as a vital stormwater distribution outlet — preventing disastrous debris-flows that have decimated Santa Barbara in the past. Brooks is also concerned about potential removal of the house.
“If a big storm comes through and takes out that house, it would sever gas lines, sewer lines, water lines and electrical,” Brooks said. “Who cleans that up?”
Though habitat loss would be devastating for the endangered species living on the Salt Marsh, Brooks said construction may also have long term impacts on California’s depleting coastal wetlands. Their conditions are already grim – with only 3-5% remaining in the entire state.
Looking ahead
The court hearing is now scheduled for July 29. With an administrative record of over 4,300 pages, Judge Anderle said more time was needed to address this nuanced issue.
Massara said he was disappointed by the postponement, but also appreciated Judge Anderle’s desire to sift through the “voluminous” records. Chytilo echoed the sentiment.
“They need to really look under the rocks,” Chytilo said.
