Alexander Avenue/Danes Drive Intersection Improvement Project

The Finding of No Significant Impact (FONSI) is anticipated to be released in early May 2012. When it is released it will be available on the park's PEPC website, under the Document List link. In addition to the FONSI a Response to Public Comments will also be available.

In compliance with the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), the National Park Service (NPS) and the Golden Gate Bridge, Highway and Transportation District (GGBHTD) have prepared an Environmental Assessment/Initial Study (EA/IS) for the Alexander Avenue/Danes Drive Intersection Improvement Project.

The purpose of the project is to correct existing deficiencies and substandard roadway conditions at the Alexander Avenue left-turn lane to Danes Drive. The project identifies actions within the project area that address a number of deficient multi-modal transportation conditions including: inadequate roadside shoulder width to handle shared bicycle, pedestrian, and automobile use; and skewed intersection geometry.

All of the action alternatives would result in the reconfiguration of the Alexander Avenue/Danes Drive intersection, lengthening of the left-turn lane along Alexander Avenue, and widening of the shoulders along both sides of Alexander Avenue within the project limits. The Agency Preferred Alternative is the 8-Foot Rockfall Catchment Alternative (Alternative D).

The other action alternatives, the 16-Foot Rockfall Catchment Alternative (Alternative B), and the 5-Foot Rockfall Catchment Alternative (Alternative C) vary from the Preferred Alternative in the extent of excavation required for the improvements to Alexander Avenue and the method for reducing rockfall hazards associated with the cut slope along the east-side of Alexander Avenue.

The public review period began on December 23, 2011 and ended on January 27, 2012. The EA/IS is available online on the park's PEPC website.
