Larsen Creek Bridge Replacement Project

Larsen Creek Bridge Replacement Project

The project proposes to replace two bridges spanning Larsen Creek. The upstream bridge (closest to the clubhouse) is currently 34-feet long and 10-feet wide. This bridge is located in an open field and is easily accessible for construction. The creek banks are sloped and grassy. The existing bridge deck is approximately 11-feet above the thalweg. The downstream bridge is currently 40-feet long and 10-feet wide. The bridge site is in a riparian forest. Work will be accomplished from top of bank and not within the stream channel. Work involved includes the following: minor grading to place the bridge at grade (both bridges), and tree pruning and possibly removal of one tree may be required (downstream bridge). The applicant proposes to replace disturbed vegetation with native species. The new wooden bridges will be set on wood piers no closer than 10-feet from the top of the stream bank. No piers will be set in the creek. Abutments/piers will be 10-feet wide and lengths will be similar to existing. The bridges will be installed by crane, requiring no equipment in the creek. Issuance of a Streambed Alteration Agreement Number 1600-2006-0463-3 is pursuant to Fish and Game Code Section 1602.
