AI Contract Overview

The Marin Municipal Water District is executing the Mt. Tamalpais Watershed Road and Trail Master Plan through the Marin Water Phase 3 Culvert Maintenance and Replacement Project. This project is authorized under Lake and Streambed Alteration Agreement EPIMS-MAN-48729-R3, executed by the California Department of Fish and Wildlife pursuant to Section 1602 of the Fish and Game Code. The scope of work is divided into routine maintenance and standard agreement activities. Routine maintenance includes the replacement of 43 culverts, consisting of 40 upsized, one in-kind, and two downsized culverts, along with 21 upsized rock ford crossing replacements and minor rip-rap adjustments. Standard agreement activities involve the substantial upsizing of two culverts and one rock crossing at specific coordinates identified as EG-8, SG-16, and PM-05. Technical specifications indicate that existing culvert diameters ranging from 6 to 24 inches will be replaced with culverts ranging from 18 to 42 inches. The project spans numerous locations across Marin County, including various creeks and reservoirs such as Phoenix Creek, Lagunitas Creek, and Kent Lake. Environmental impacts for routine maintenance are estimated at 0.30 acres of permanent and 1.09 acres of temporary stream habitat impact, while standard activities will result in 0.01 acres of permanent and 0.05 acres of temporary impact. No riparian trees will be removed. The project is managed by the Marin Municipal Water Agency, with Eric McGuire serving as the lead agency contact, and is subject to a Mitigation Reporting or Monitoring Plan adopted by the California Department of Fish and Wildlife.
