Lenevar Avenue Sanitary/Storm Sewers and Water Mains

Staten Island, New York<br style='line-height:2px'>New York City Department of Design and Construction

This $18 million project was performed in designated sections of the NYCDEP Staten Island Bluebelt, ecologically sound and cost-effective stormwater management areas with natural drainage corridors, including streams, ponds and other wetland areas. Sites within the vicinity of Lenevar Avenue are designated as fresh water wetlands, and this project involved the construction of Best Management Practices (BMP) facilities to improve the quality of storm waters discharged into Lemon Creek. To help achieve this goal, HAKS provided Construction Supervision services for the construction of water mains, installation of piles, chamber construction, clay and concrete sewer pipe, elliptical RCP and flat top rectangular reinforced concrete sewers, new curbs, sidewalks, catch basins and chute connections and roadways. Work also included gas main support and relocation; electrical ducts support, replacement and relocation; and special care excavation.

The Lenevar Avenue project involved three distinct BMP stormwater management facilities located within the Lemon Creek watershed. These BMP areas contained a storm water pond that provided for extended detention times, outlet stilling basins and swales that channeled the flow through naturally vegetated areas. The construction incorporated erosion and sediment controls, along with headwalls and retaining walls, plantings and landscaping.

Following the sanitary sewer installations, home owners were able to disconnect their units from the individual septic tanks serving their homes and reconnect to the new sewer line in the street. Before the sewer lines were installed, homes along the street were surveyed to determine the best locations for connecting each individual waste line to the new sewer line. The lines and BMP facilities quickly removed storm water runoff and prevented flooding that often accompanied rainfall in the past.
