What’s Happening at Hawk Hill? About 93 acres of habitat for endangered mission blue butterflies must be restored in the southern Marin Headlands to compensate for impacts from road and trail construction that are a part of the Marin Headlands Fort Baker Transportation Management Plan. For more information, please see the attached project document.
Field Road Waterline Replacement
Using Fiscal Year 2010 & 2011 Repair/Rehabilitation funding, the park is planning to replace the existing 6" cast iron water supply system within the Marin Headlands. Some sections of the present water system are approaching 100 years of age. The new water supply system upgrades will use HDPE pipe, fire hydrant replacements or repair, new pumps, and valving. The new water system will meet new, contemporary standards and improve overall operation. The first phase of this work will occur on Field Road in Fort Barry. The construction of this phase will be completed by the end of the summer of 2012. The second phase of this specific section of underground pipe installation in Ft. Barry will occur on Simmonds and Roesenstock Roads. Traffic control measures will be arranged to facilitate periods of single lane alternating traffic.
Point Bonita Bridge Replacement
Using federally appropriated Line Item Construction Program and Franchise Fee funds, the park is planning on replacing the deteriorated Point Bonita Suspension Bridge. Built in 1954, the bridge serves as the only land access to the lighthouse for both ship navigational safety and NPS interpretive opportunities. In July 2010 a Comprehensive Project Agreement between the Federal Highway - Central Federal Lands Division (FHWA-CFLHD), NPS Denver Service Center and NPS Golden Gate was approved, outlining the roles/responsibilities and schedule for completion of the compliance, resources/design and construction work. Resources/design work was completed by early June of 2011 and construction was completed in April of 2012. The project also entails stabilization of the west abutment using stainless steel cable netting and shotcrete sculpted to have an appearance compatible with the adjacent cliff face.

Rodeo Beach Parking Lot
Construction actions occurring in 2012 or later include the restoration of the Rodeo Beach parking area. The Rodeo Beach unpaved parking lot would be removed and restored to its pre-existing wetland condition to re-establish natural hydrologic and wetland conditions by reversing past human disturbances to natural processes. The removal would also reduce erosion in that area. Associated actions include removing fill from the unpaved parking lot above Rodeo Beach, grading the site to re-establish pre-disturbance contours, and restoring natural hydrologic conditions to establish a native marsh community. The project would result in the net restoration of 1.3 acres of wetland habitat from what is now upland habitat and an unpaved parking lot.
The proposed wetland restoration project on the unpaved portion of the Rodeo Beach parking lot is expected to improve water quality by reducing the area of erodible and exposed surfaces. In addition, aesthetic improvements would result from the removal of road fill in the shoreline area, affording visitors a visual connection with the Pacific Ocean, beach, and upslope wetlands. A new transit stop/shelter would be provided, and stairs and a fence to the beach would be constructed on the south side of Mitchell Road near the Rodeo Beach to improve access and reduce erosion.
With the restoration of the Rodeo Beach parking area, there will be a loss of parking spaces. Replacement parking would be provided within Fort Cronkhite, possibly at the maintenance yard, which is located east of Fort Cronkhite.
Changes to this area will be guided by the Fort Cronkhite Cultural Landscape Report (CLR) and the General Management Plan to avoid adverse impacts to the historic district. The construction associated with wetland restoration of the Rodeo Beach unpaved parking lot would be done during the dry months of the year to minimize the amount of exposed and erodible surfaces. Following grading, bare surfaces will be protected with plantings native to the area and erosion control materials. During the construction phase, the public will be notified of any access restrictions.
Rodeo Valley Trail
Planned improvements for this trail will enhance a key trail link in the Marin Headlands, allowing bicycles and pedestrians to better access the Marin Headlands from Fort Baker and Sausalito. The project will also restore riparian habitat, reduce trail flooding during the winter, and create a safer, more scenic alternative to Bunker Road. Trail improvements started in summer of 2011 and more improvements will continue beginning in July 2012. For more information on this project, click here.
