Construction over the last couple of weeks has focused on some of the green infrastructure (GI) improvements on the project: the bioswale that runs along the north side of the trail and a biorentention ponds on the west end of the project. Both of these facilities are comprised of multiple layers of soil and porous stone to clean contaminants from stormwater and contain as much storm runoff on site as possible to prevent sediment erosion downstream.
The project's electrical subcontractor has began installing necessary wiring running between newly installed manholes and lightpoles that will power the 52 LED lights on the trail. Additionally, staining of the East Retaining Wall is nearly complete. This is a retaining wall of nearly 500 CY of cast in place concrete using formliners to mimic the surrounding stone retaining walls.
Activities for the remainder of April will focus on preparing for the final trail installation. Crews will perform final grading and placement of a porous stone base before laying down two layers of a permeable pavement. Paving is scheduled for late this month and the entire operation will extend into May.
