Over the past month, the entire length of the site has seen the installation of plenty of riprap (large stone used to slow the velocity of water and prevent erosion). Over 6000 square feet has been placed within a channel that will run on the north side of the trail. Construction has also progressed on another storm water element: elliptical concrete pipe and corresponding manholes have been installed close to the west entrance of the trail that will carry stormwater into the stream.
Construction activities are currently on-going at the east end of the project along the ramp from Klingle Road to Beach Drive. In order to allow for an asphalt sidewalk to connect the Klingle Valley Trail to the Rock Creek Trail, an existing retaining wall has been removed and will be replaced with a stone masonry wall that will match the stone work used for the adjacent bridge at Porter Street.
Upcoming scheduled activities are focused on the rehabilitation of existing DC Water sanitary sewers within the project. This work will be performed by a method called 'cured in placed pipe' (CIPP) which allows a new liner to be installed within the existing pipe and does not require any significant amount of excavation to expose the pipe. The schedule for this work is being closely coordinated with DDOT and DC Water but will require some traffic control along Connecticut Avenue during off-peak hours.
