Weston & Sampson was selected by the East of Hudson Watershed Corporation (EOHWC) to provide preliminary evaluation, detailed design, bidding, and construction phase services for several stormwater retrofit projects in Putnam and Westchester counties in New York. The projects were funded by the NYCDEP through EOHWC.
The existing gravel parking lot at the Putnam National Golf Course was one of the sites for stormwater drainage improvements. The primary goal of the project was to pave the existing gravel lot and install a subsurface stormwater collection, treatment and infiltration system that is approximately 1 MG of stormwater storage. Paving included 40,000 square feet of conventional impervious asphalt and an additional 20,000 square feet of pervious paver blocks.
The project also included a variety of other improvements including complete new energy efficient LED lighting, decorative segmented block retaining walls, stairs, railings and walkways. The project provided effective stormwater treatment and a much needed face-lift for the parking lot and course entrance that is easy to plow and maintain.
In an article titled “Proactive Pollutant Removal,” published in the Water & Waste Digest, Joeseph Zongol, PE, NICET III, worked with EOHWC and Cultec Inc., and Ben Ciccone Inc., to reduce phosphorus in East of Hudson Watershed drinking water by installing a subsurface filtration system to mitigate contaminates from flowing into the drinking water during storms. The system includes 240 low-profile subsurface storm water management chambers, with 410 filter fabric envelops. Runoff from different portions of the lot get filtered either through the new system or through stormwater collection structures and into the infiltration system.
