Lake Tonetta Subsurface Gravel Wetland

The Lake Tonetta Subsurface Gravel Wetland was recently completed in the Town of Southeast, New York. This stormwater retrofit project, located in the New York City Croton Reservoir Watershed, captures and treats stormwater runoff from a 57 acre highly developed residential area and outlets to the Great Cedar Swamp upstream of Lake Tonetta. In addition to improving the quality of runoff entering a sensitive and highly functional wetland, this practice provides necessary pollutant removal to meet the New York State Department of Conservation Enhanced MS4 requirements. The subsurface gravel wetland consists of a sediment forebay and two submerged wetland cells which are densely vegetated on the surface and underlain by wetland soil and layers of variable sized crushed stone with a geocomposite clay liner to maintain wetland hydrology. Stormwater is filtered as it flows horizontally through the subsurface medium. This practice thus combines sedimentation removal on the surface with nutrient removal in a subsurface zone. The innovative approach was selected because it offers a high level of treatment within a relatively small footprint with low maintenance. The project represents a relatively new technology for stormwater treatment in the United States and is unique in that up to the 100-year design storm flows (230 cfs) are routed through the forebay and wetland cells. The project, which was completed and placed on-line in June 2014, was funded by the Hudson Watershed Corporation.

Burnt Hill Park project presented at the Annual Connecticut Recreation and Parks Association Conference

Burnt Hill Park, located in Hebron Connecticut, was the subject of a presentation at the Annual CRPA conference held at the Mohegan Sun. The project, which included five athletic fields and amenities including a park operations building, pavilion, bathroom building and walking trails, was designed with Nathan L. Jacobson & Associates as the prime consultant and constructed in 2008-2009. The park is a great example of a multi-use facility which incorporates recreational athletic fields in a park like setting consistent with the rural character and nature of the Town of Hebron. The presentation, which was given by Tom Fenton, P.E., Principal Engineer at Nathan L. Jacobson & Associates and Mike Fortuna, AIA, of TLB Architects, focused on the construction process and project management. A prior presentation to CRPA by the same team, focused on the design, permitting and approval process.
