Photo 1:  Groundwater monitoring wells will be installed throughout the site to collect data that will help evaluate the success of the wetland creation sites.  This photo shows a completed installation of a monitoring well near the site entrance off County Line Road. Photo 2: In this photo, earth being removed from the mitigation site has been stockpiled in a staging area for transportation to an off-site location. Photo 3: Construction access is provided by placing geotextile and stone to improve stability for construction equipment in upland areas  The stone will be removed at the end of construction activity. Photo 4: As a result of public input, a temporary stream crossing was installed at the Little Neshaminy Creek.  The crossing will allow for construction vehicles to access the north side of the mitigation site without disturbance to local residential streets.   Looking northwest, this photo shows the temporary stream crossing.  Eight (8) pipes are used to maintain flow while a stone overlay provides support for construction vehicles.  After major construction activity is complete on the north side of the mitigation site, the stream crossing will be removed. Photo 5: Construction mats have been installed at sensitive areas within the site to minimize compaction of the soils along the haul road.  The mats help protect the mitigation site and result in easier driving conditions for large construction vehicle.  The mats will be removed at the end of construction activity. Photo 6: A weir structure is installed at the southern spillway of Creation Site B.  Several of these structures will be installed throughout the mitigation site.  Their purpose is to help regulate water levels in the wetlands to enhance the success of the mitigation site. Photo 7: Berms will be installed to help retain water in each creation site.  This photo, looking northwest, was taken in Creation Site C and shows the rough grading for one of these berms.           Project News       Community Newsletters       Related Sites       Subscribe for E -Mail       Submit a Question or Comment       FAQ          Twitter
