Aside from their visual benefits in urban environments, aesthetic gardens also have many environmental benefits. Urban gardens naturally insulate rooftops and building surfaces, increase air quality in urban environments, promote sustainable building practices, and collect and maintain storm water overflow.
Stormwater Policy in NYC
The New York City Department of Environmental Protection (DEP) has promulgated new stormwater performance standards for new development and redevelopment in the combined sewer areas of New York City.* The DEP sets limiting criteria for the “allowable flow” from development lots in order to manage the influx of stormwater into the city’s sewer system. These new standards, effective July 2013, require greater on-site storage of stormwater runoff and slower release to the sewer system during rain events. (*Chapter 31 of Title 15 of the Rules of the City of NY, Rule Governing House/Site Connections to the Sewer System Standards for Release Rates)
Stormwater Performance Standards
The revised EPA stormwater standards call for innovative techniques that retain storm water onsite for recycling or off peak release into the sewer system. Rooftops, parking lots and open spaces have all been identified as space that can be utilized for stormwater source control.
Water Management Services
Living Restoration can develop and implement an effective stormwater storage and management system to help building owners achieve compliance with the upcoming EPA standards for stormwater runoff.
Water Catchments and Cisterns
Cisterns are easily installed and built to catch and store stormwater for later usage or release.
Water Recycling Consulting
Stormwater can be captured and used for onsite purposes such as irrigation and greywater reuse.
A vegetative rooftop reduces the area of impervious surface on a property and can be designed to provide temporary storage for stormwater.
