Larkspur Planning Commission approves design review for 17 Ridgeway Lane with construction conditions

The Larkspur Planning Commission on Feb. 11 approved design review, a floor-area-ratio (FAR) exception, a slope-use permit and two variances for work at 17 Ridgeway Lane (PLN24-024), including a new one-car garage, a funicular and stairs, and associated site stabilization work.

Staff described the project as a request to allow a 0.42 FAR (about 1,602 square feet) where 0.16 (about 600 sq. ft.) is allowed, permit approximately 60 cubic yards of cut and fill, allow a one-car garage at or near the lot line, and allow a funicular with a 4-foot side setback where 5 feet is required. Planning staff recommended approval subject to findings, conditions of approval, and a Class 30 CEQA exemption; staff also recommended adding a condition to ensure compliance with the city’s noise limits in Larkspur Municipal Code section 9.54 for the life of the use.

The applicant, architect Earl Weiss, said the work is intended to stabilize failing retaining walls, improve access and circulation for fire and service vehicles and to allow the owner to age in place. Weiss described the funicular as an electric, rubber-wheeled track system similar in noise to an electric car and said the design minimizes ground contact to protect the redwood tree on site. Weiss estimated site work and construction sequencing could take roughly six to eight months, with most of the heavy site grading early in the schedule and the funicular installation completed in a few days after the foundation work.

Neighbors who spoke during the hearing raised access, repeated construction impacts, drainage and the condition of the privately maintained lane known as Ridgeway Lane. Jay Blumenfeld (12 Ridgeway Lane) and Judith Hartman (33 Millard) told commissioners they had been inconvenienced by prior work, described repeated obstruction of access during prior construction, and asked for firm construction management commitments. Blumenfeld said geotechnical work had in one instance gone forward without USA markings and that parking and staging on the lane had blocked emergency access in the past.

Commissioners discussed whether the city could require repair of a private lane and noted enforcement challenges for private roads. Planning staff said the city could document pre- and post-construction conditions and that, if needed, staff would have an engineer document site conditions for enforcement of any condition tied to the project. In deliberations commissioners emphasized the need for a robust construction management plan and clear notification to neighbors before heavy work such as concrete pours or deliveries.

The commission’s approval included the project-level entitlements (design review, FAR exception, slope-use permit, variances, and the CEQA exemption) and several specific conditions: final plans must show compliance with Larkspur Municipal Code section 9.54 (noise control) for the life of the use; the applicant must prepare and implement a construction management plan that addresses notification, staging, parking for workers and heavy equipment, and access protections agreed with immediate neighbors (neighbors identified at the hearing included 12 Ridgeway Lane and 33 Millard); and the applicant committed to repair and repave the back portion of Ridgeway Lane (approximately 25 feet measured from the end of Ridgeway, as agreed at the hearing) where demolition and staging occur. The commission recorded a unanimous roll-call vote approving the motion; the chair announced a 10-day appeal period.

The approval does not resolve private easement or civil disputes among property owners. Staff and commissioners emphasized those matters remain civil issues among property owners unless a clear public-rights issue is present or the city is directed otherwise by legal counsel. Staff noted the project will return to building-permit review where detailed drainage, foundation, and other technical conditions will be addressed and where the Ross Valley sewer lateral noted by neighbors may need coordination with the sewer district.

Why this matters: the project alters a steep, small lot and requests multiple exceptions to Larkspur development standards; the approval sets a practical example of how the commission balances tree protection, slope stabilization and access improvements with neighbors’ requests for clear construction controls and lane repairs.
