Ferndale Coastal Development Permit Record No.: PLN-2025-19147 APN: 100-181-003 Ferndale area A Coastal Development Permit (CDP) for drainage improvements for the City of Ferndale, located just north of the City limits. The overall project is located both within the City of Ferndale and just outside, within County jurisdiction, and includes the replacement of existing storm drain inlets and piping along Arlington Avenue, new piping and swales along 5th Street, enlargement of the drainage swale in the pasture north of Van Ness Avenue, and creation of a stormwater detention pond in the northern extent of the pasture. Work within the Coastal Zone (and subject to this CDP) includes areas north of Van Ness Avenue. The existing culvert crossing at Van Ness Avenue (which flows into the pasture) would remain in place, and a second, parallel culvert installed. Five to eight trees and energy dissipating rock would be added to the culvert outlets to reduce potential scouring and erosion. The existing drainage swale through the pasture and proposed stormwater detention basin would be graded and revegetated with native grasses. The swale within the pasture north of Van Ness Avenue would contain a minimum bottom width of three feet and side slopes of 3:1 and daylight to existing grade. The new swale would have an approximate 0.3 to 0.5% slope and maximum excavation depth of three feet. The swale would then transition to a 0.5-acre stormwater detention basin on the County-owned parcel. The detention basin would have 3:1 slide slopes and daylight to existing grade and contain a maximum excavation depth of two feet. Following Project implementation, the pasture would remain seasonally grazeable which is consistent with current management.
