Corte Madera approves second driveway to enhance emergency access at 800 Corte Madera Avenue

The Corte Madera Planning Commission convened on April 8, 2025, to discuss a design review and variance application for a second driveway at 800 Corte Madera Avenue. The meeting, led by Chair Chase, focused on the proposal aimed at enhancing emergency egress and improving access for fire department services.

The application, identified as PL24-0048 and PL25-0016, involves constructing a second driveway on the northern portion of the property, which is approximately 11.38 acres in size. This area is zoned R1C and is characterized by steep slopes, averaging 52%. The proposed driveway would increase the lot coverage by about half a percentage point, bringing the total to 4%. Notably, the R1C zoning district does not impose a specific lot coverage standard, but rather reviews coverage through the design review process.

Key features of the project include the construction of retaining walls, which will range from half a foot to 12 feet 5 inches in height, and the installation of an entry gate, grading, drainage, and lighting. The project also entails the removal of 47 trees, with plans to replant 32 trees. The site is located near the Alto Bowl Open Space Preserve and is bordered by residential properties.

The proposed driveway will not facilitate any additional development beyond what is permitted by the zoning ordinance. A portion of the driveway will extend into the town right-of-way, necessitating a license agreement between the property owners and the town for the proposed improvements.

Grading for the driveway will involve 370 cubic yards of cut and 875 cubic yards of fill, requiring town council approval for the grading permit due to the total exceeding 1,000 cubic yards. The meeting included detailed discussions on the implications of the proposed changes, particularly regarding the environmental impact and community access.

The commission will continue to review the application, with further discussions anticipated in upcoming meetings. The outcome of this proposal will be significant for both the property owners and the surrounding community, particularly in terms of emergency access and environmental considerations.
