AI Contract Overview

The Larkspur Marina Bulkhead Replacement Project, executed by the California Department of Fish and Wildlife under Lake and Streambed Alteration Agreement EPIMS-MAN-56958-R3 and Section 1602 of the Fish and Game Code, authorizes the Larkspur Marina Property Owners Association to replace an existing bulkhead wall in Corte Madera, California. The project involves constructing a new bulkhead on the waterside of the existing structure using fiber reinforced vinyl sheets installed via a vibratory method with a small excavator, specifically prohibiting pile driving. Construction will be managed from two floating platforms, and the process includes removing the existing concrete cap, filling the gap with compacted material, and installing a new cap. To mitigate environmental impact, the project mandates the use of silt curtains and turbidity controls. Operational constraints include closing lake inlets by November 30 to protect larval Longfin smelt and maintaining the functionality of the lake outlet's one-way duckbill valve. A pump system connecting the lake to the Corte Madera Creek side channel will be used to manage water levels for flood control and water quality. The project will result in 8,538 square feet of permanent impacts from construction and fill, as well as 156,400 square feet of temporary impacts due to shading from platforms and silt curtains, which must be removed immediately upon completion. This project is granted a Class 2 categorical exemption as it replaces an existing structure with one of substantially the same purpose and capacity.

Full Description

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-MAN-56958-R3, pursuant to Section 1602 of the Fish and Game Code, to Larkspur Marina Property Owners Association. The Project is limited to replacing the existing bulkhead wall by constructing a new bulkhead wall built on the waterside of the existing bulkhead along the Lake shoreline. The new bulkhead will be constructed with fiber reinforced vinyl sheets and placed via vibratory method with a small excavator, no pile driving will take place. Construction of the new bulkhead will be conducted from two small floating platforms approximately 15 feet wide by 30 feet long. The concrete cap of the existing bulkhead will be removed as necessary. The space between the existing bulkhead and the new bulkhead will be filled with compacted fill material and a new cap will be installed. Turbidity controls (e.g., silt curtains or similar) will be used around the active work areas, which will allow suspended solids to drop out and minimize turbidity in the Lake. The Lake inlets will be closed off by November 30 which is the end of the work period for larval Longfin smelt (Spirinchus thaleichthys) for the duration of construction activities. The Lake outlet, which is controlled by a one-way duckbill valve, will remain operational and used to lower lake levels as necessary to maintain flood control operations and water quality. A pump system connecting to Corte Madera Creek side channel and the Lake will be used to raise the level of the Lake as necessary during wet and dry seasons to maintain water quality, flood control, and integrity of the existing bulkhead. An existing easement over the outfall pipe in the northeast section of the Lake will be used for access to the floating platforms and staging materials and equipment. The Project will result in 156,400 square feet (3.59 acres) of temporary impacts associated with shade caused by the floating platforms traversing through the Lake and the use of silt curtains, which shall both be removed immediately after Project completion. The Project will result in 8,538 square feet (0.196 acres) of permanent impacts associated with bulkhead construction and fill.
