A regulation that promotes the use of on-site natural processes to attenuate pollution, manage hydrology, and provide open space.


By managing hydrology and pollution on-site, a developer can reduce stormwater sewers and detention basins.  Natural landscaping can improve the function of open space and promote the infiltration of runoff.


Green infrastructure still requires maintenance, and landowners may be unfamiliar with these requirements.  Effectiveness may depend on soils and temperature as well.
