Document Description
Note: FEIS The purposed of the project is to contain the 1-percent flood exceedance (100 year flood event) on West Little Llagas Creek through the Community of Morgan Hill, to ensure no induced flooding on Llagas Creek by upstream modifications along the reaches downstream of Morgan Hill, and to provide 10-percent flood exceedance protection on East Little Llagas Creek. The project includes the following major elements: construction of flood protection and geomorphic features; construction of access roads for maintenance purposes; installation of a permanent 6-foot vinyl chainlink fence and habitat enhancement. The project will result in impact to 25.61 acres of California tiger salamander upland and aquatic dispersal habitat, including temporary impacts to 21.75 acres and semi-permanent impacts to 3.86 acres of habitat. The project is expected to result in incidental take of California tiger salamander, which is designated as a threatened species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
