Alexander Avenue/Danes Drive Intersection Improvement Project
The Finding of No Significant Impact (FONSI) was released in July 12, 2012. It is available for download on the park's PEPC website, under the Document List link. In addition to the FONSI a Response to Public Comments is also available. The FONSI describes the rationale used in selecting the alternative for implementation, and provides an explanation of why it will have no significant effects on the human environment.
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.
The Selected Alternative is the 8-Foot Rockfall Catchment Alternative (Alternative D). This alternative will allow for two 12-foot-wide vehicle lanes, a 12-foot-wide left turn lane, and a 5-foot-wide combined shoulder and bicycle lane on both sides of Alexander Avenue. A temporary rockfall barrier will be installed between the catchment ditch and roadway. This alternative will result in a final east cut slope height of approximately 77 feet and the total width of excavation will be approximately 91 feet.
Excavation of the rock cut will occur during the first phase of construction to provide additional space to ensure that one traffic lane in each direction could remain open during subsequent phases of construction. During this initial construction phase traffic will be routed to the furthest west section of the roadway.
The EA/IS is available online on the park's PEPC website.
