Mendocino CPA approves clustered accessory development and septic work at Fort Bragg bluff parcel with conditions

The Mendocino County Coastal Permit Administrator approved a coastal development permit March 27 to allow a cluster of accessory structures — including a guest cottage, music studio, garage, workshop, covered porches, roof-mounted solar and associated septic work — on a bluff-top parcel at 29020 North Highway 1, near the mouth of the Ten Mile River north of Fort Bragg.

The permit (CDP 2021-0046) authorizes construction inside building envelopes previously established by the California Coastal Commission, conversion of one test well to a production well under an earlier emergency permit and replacement of an on-site septic field. County staff said the project is categorically exempt from CEQA provided the recommended conditions are met; the Coastal Permit Administrator approved the project with those conditions.

County planner Jesse Waldman told the administrator the parcel is about 3.65 acres, is mapped as highly scenic, is west of the first public road and lies within rural residential zoning combined with a planned-unit development district. Waldman said the Coastal Commission previously established two building envelopes on the parcel and that the applicant had revised building heights and colors to reduce visual impacts. "As long as the conditions are followed within this staff report, the project is found to be exempt from CEQA," Waldman said.

During public comment, neighbor Kathy Boyle, who said she lives adjacent to the parcel, urged protections for wildlife and raised concerns about proximity of new well drill sites to nearby domestic wells. "There's a pair of eagles that actually live in that tree and they actually nest in that tree and actually produced offspring last year," Boyle said. County staff and the project biologist said no tree removal is proposed and that preconstruction bird surveys and other avoidance measures will be required to avoid impacts to nesting raptors.

County staff described required conditions of approval that include: planting screening along the eastern and southern parcel boundaries per Coastal Commission recommendations; an "animal‑friendly" low fence to limit encroachment into environmentally sensitive habitat areas recommended by the California Department of Fish and Wildlife (CDFW); a discovery clause and cultural‑resources training per the archaeological report; preconstruction surveys and monitoring to avoid impacts to nesting birds and other special‑status species; and a deed restriction for the guest cottage prohibiting overnight rental and kitchen facilities as allowed under local rules for guest cottages.

On water and wells, the staff and project representatives said the emergency permit (EM2021-0003) allowed test drilling and the first drilled well provided sufficient water; environmental health review and well permits have been completed for the new well and would be finalized in coordination with the county. The planner said applicants are allowed up to three drill sites under the environmental health permit process; in this case only one production well is proposed to be converted from a test well.

The Coastal Permit Administrator emphasized that the county's Local Coastal Program protects public vantage points — not private neighbor views — but recommended that staff carefully review the project's planting plan when it is submitted. "A planting plan or the vegetation doesn't grow immediately... it might take a year plus or longer, but eventually you'll get that natural, visual screening which is a great alternative to a large block wall," the administrator said before approving the project with staff conditions.

The decision requires submittal of a revised site plan showing the low fence location, a planting plan with native species as advised by CDFW, completion of required archaeological measures if artifacts are encountered, compliance with environmental health requirements for septic permitting, and the recorded deed restriction for the guest cottage prior to issuance of building permits.

The applicant's agent, Amy Wynn of Wind Coastal Planning and Biology, and staff said they supported the staff report and conditions; no votes against the proposal were recorded in the hearing transcript. The landowner was not present at the hearing.

Going forward, staff will review the planting plan, coordinate archaeological or tribal monitoring steps if needed, finalize environmental health paperwork for the well and septic permits and ensure the deed restriction and other conditions are recorded before building permits issue.
