Intent
Limit disruption of natural water hydrology by reducing impervious cover, increasing on-site infiltration, reducing or eliminating pollution from storm water runoff, and eliminating contaminants.

How do we do this? Well some ways to do this is the use of recharger pits that will collect the rain and disperse it in the ground gradually over time relieving the local storm water system and preventing overflow and contamination of local streams and rivers.

Another method is to use pervious materials for surfaces such as local vegetation that requires little watering and limit the impervious materials on the site such as bituminous black top paving and concrete paths and driveways.

Green or vegetative roofs can help and early planning and coordination with your site engineers will make for a well conceive project in terms of storm runoff with your design.

Most towns on large scale projects like to see engineered drawings with storm water collection calculations by an civil engineer to see the amount of water it is design for to handle given the proposed developments without negatively effecting the local storm water system.

A well thought out landscape plan provided by a landscape architect can also help engineers make good decision in potential storm water run off.
