Document Description
CDFW has executed Lake and Streambed Alteration Agreement No. 1600-2015-0387-R3, pursuant to section 1602 of the Fish and Game Code to the project Applicant, Andrew Poster representing City of Mill Valley Department of Public Works.
Project is limited to a permanent tide gate replacement within a Class I tidal channel tributary to Bothin Marsh a tributary to Arroyo del Corte Madera de Presidio. This feature will be constructed as part of the Miller Avenue Improvement Project. The existing 30-inch culvert passes beneath a sidewalk on the north side of Miller Avenue. The culvert is fitted with a tide gate that is failing due to the gate not closing and instead allowing tidal water to flow pass freely upstream. Upstream of the culvert is a 3-foot wide deep channel with steep banks dominated by ruderal and brackish vegetation. Downstream of the culvert is mud-bottom tidal channel that flows east to Bothin Marsh. Permittee will replace an existing 30-inch diameter, 10-foot long culvert and malfunctioning flap gate with two 48-inch diameter RCP culverts and a new floating flap gate that will prevent tidal intrusion into the drainage channel while allowing stormwater to escape.
