Sir Francis Drake Boulevard Improvements SEA/SIS w/FONSI

The Draft Supplemental Environmental Assessment/Subsequent Initial Study (SEA/SIS) with proposed Mitigated Negative Declaration for the Sir Francis Drake Boulevard Improvement Project is available for public review and comment from June 19, 2018 to July 18, 2018. The Federal Highway Administration Central Federal Lands Highway Division (CFLHD), in cooperation with Marin County and the National Park Service (NPS), is proposing improvements to Sir Francis Drake Boulevard within Point Reyes National Seashore in Marin County, CA. The project includes improvements to approximately 12 miles of Sir Francis Drake Boulevard from the intersection with Pierce Point Road to the intersection with Chimney Rock Road. The proposed improvements primarily consist of resurfacing, restoring, and rehabilitating Sir Francis Drake Boulevard in a manner that will closely follow the existing roadway. In general, the roadway would be widened 1 to 6 feet to maintain a consistent 24-foot width with two 11-foot travel lanes and 1-foot shoulders. The purpose of the project is to restore the structural integrity of the roadway and enhance safety for all users while reducing ongoing maintenance requirements. In accordance with the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), a joint EA/IS was prepared that analyzed these improvements to the road and was distributed for public review in July 2015. A Finding of No Significant Impact/ Mitigated Negative Declaration (FONSI/MND) was issued in August 2015.

Since issuance of the 2015 FONSI/MND, improvements have been proposed and evaluated under this SEA/SIS include replacing the existing culverts under SFDB at Schooner Creek with a single-span bridge, and restoring and stabilizing approximately 710 feet of SFDB that has severely eroded. To compensate for permanent wetland impacts as a result of roadway improvements, part of the parking lot at the Drakes Beach would be restored to a wetland, and two ponds would be constructed within Home Ranch to provide California red-legged frog aquatic breeding habitat. Actions at Drakes Beach and Home Ranch extend beyond the original study area analyzed in 2015.
