Project Info
- Title
- South Fork of Gallinas Creek Tributary Free-Span Bridge
- Description
- The Operator proposes to construct a clear-span bridge for a road crossing of an unnamed stream in San Rafael, Marin County, as part of a 134-unit residential development. The stream on which this project is located is an ephemeral tributary which eventually drains into the Civic Center lagoon and the South Fork of Gallinas Creek, thence San Pablo Bay. Also included in the project will be the installation of several underground utility lines at the bridge site, and grade control structures at the upstream and will affect approximately 40 linear feet of channel, resulting in an impact of 720 square feet of stream channel. Additionally, drainage structures will be constructed and/or rebuilt where the channel enters and exits the property to allow the continued flow through the existing channel. Construction and modification of these structures is expected to impact approximately 100 square feet. Approximately 0.37 acres of wetland and about four acres of native grassland will be created adjacent to the stream as part of the mitigation for the residential development.
