Project Description

The work to be done consists, in general, rehabilitation of approximately 1.84 miles of trail by pulverizing the existing pavement, recompacting, and repaving with asphalt concrete on top. The rehabilitated trail would follow the existing trail alignment. The rehabilitated trail will be the same width as the existing trail, which varies between approximately 4 and 6 feet wide, a minimum of 4 feet wide will be maintained throughout the entire rehabilitated trail. 

The work will also consist of creek bank stabilization at three locations along the trail.  Stabilization will consist of keystone or soldier pile wall construction, biotechnical bank improvements, reconstruction of creek channel, revegetation and plant maintenance.
