esplanade biofilter prep

We haven’t talked about stormwater management yet. As part of the project, a series of esplanade biofilters are being installed along the roadway edges. Esplanade biofilters are strategically placed so that they collect stormwater runoff from the roadways and treat the stormwater before it enters the drainage system. Drainage from these systems eventually discharge to a waterbody, such as Hobbs Creek, the West Branch of the Piscataqua River, and the Presumpscot River. Photo’s above show the biofilters being assembled, prepared, and connected to the storm drain system.
