SCOPE
This project, the 'CAT/RAMP + Gap' Project, is part of the City of Alameda’s overall Cross Alameda Trail (CAT) project, which is envisioned as a premiere crosstown, low-stress four-mile bicycling and walking corridor that will connect the west side of the island to the east, from the former Naval Air Base to the Miller-Sweeney (Fruitvale) Bridge. The CAT is being constructed in segments. This CAT/RAMP + Gap project, running parallel to and south of Ralph Appezzato Municipal Parkway, between Main Street and Constitution Way will total approximately 0.9 miles in length, and is divided into two distinct sub-segments: 1. Ralph Appezzato Memorial Parkway (Main Street to Webster Street) Construction of separate walking and bicycling paths (asphalt concrete), plus a decomposed granite jogging path, in the City-owned abandoned railroad right-of-way. This approximately 70 foot wide right-of-way sits immediately to the south of Appezzato Parkway, adjacent to apartment complexes, schools, several businesses and a Boys and Girls Club. This segment will include the following additional features: a) Connector trails to at least two intersecting streets; Fifth Street and West Campus Drive, b) Pedestrian, bicycle, and ADA improvements, as well as signage at intersecting streets, c) New hardscaped, landscaped plazas at each end; Main Street and Webster Street, d) Trees, shrubs, bioretention and self-retaining areas, w/ landscaping and urban runoff control, and e) Traffic signal modifications at Fifth Street and Constitution Way, Note: This section includes significant earthwork in the excavation (or relocation and 'capping') of contaminated soils, creating the subgrade for the bicycle and pedestrian paths, with the placement of a soil cap over the majority of the site. 2. Atlantic Avenue (Webster Street to Constitution Way) Construction of separated two-way bicycle lanes on the south side of this short urban block, one half of which will be at sidewalk-grade (west of business parking lot driveway), and the other which will be at streetgrade (east of this driveway). This CAT section includes significant improvements to the two intersections, which are among the busiest in the City, to facilitate safe pedestrian and bicycle crossings. The project includes signal modifications, plus the installation of a new mid-block crossing with a flashing beacon, and the creation of a new bus stop platform. http://www.blueprintexpress.com/alameda jdybas@alamedaca.gov
