West Windsor Utilizes Environmental and Sustainable Materials in Capital Projects
West Windsor Township has utilized an environmentally sensitive product to alleviate stormwater regulatory requirements associated with the Penn Lyle Road Phase 1 Reconstruction Project. This improvement project falls under the jurisdiction of the NJ Department of Environmental Protection and the Delaware & Raritan Canal Commission because the project drains into the Duck Pond Run stream corridor and into the D&R Canal, which is a source of drinking water. Project approval from these two agencies required elevated stormwater considerations dealing with water quality and water runoff storage above the average project.
As part of the proposed road widening and sidewalk extensions that were planned for this section of roadway, the Engineering Division incorporated “porous concrete” into the design to compensate for the additional impervious coverage. Additional conventional sidewalk was also removed and replaced with the new porous concrete to further compensate for the planned improvements.
The new porous concrete allows rainfall to permeate through the sidewalk and recharge into the water table below in a controlled manner by holding the runoff in stone under the walkway. During heavy rains or during the wet season, any stormwater over what the soils can absorb enters into an underground overflow pipe and discharges directly into the Township Storm Sewer System.
The surface of the porous sidewalk will appear more granular than conventional sidewalks but is just as stable and more eco-friendly. There are a number of advantages to porous materials which have caused this to become a popular option for projects including sidewalks and parking lots.
In addition to porous concrete, the Township is also utilizing “Porous Bituminous Asphalt” in construction of a new 76 space parking area located next to the Babe Ruth Baseball Field in Community Park. The porous asphalt functions similar to the porous concrete and has the same stability of conventional blacktop with a slight difference in appearance.
Mayor Shing-Fu Hsueh stated, “The use of porous materials is considered to be a sustainable initiative because of the filtering and recharge of stormwater it achieves. This type of product promotes infiltration into the ground, reduces the amount of pollutants carried into the storm sewer system & waterways, and reduces peak runoff velocity and volume.”
