Stormwater Management
Runoff from rainwater carries a variety of non-point source pollutants, such as chemicals, nutrients, and sediments. These pollutants are transported across impervious surfaces, such as roofs & parking lots, and into local waterways either directly or through storm sewers. Stormwater runoff is the most common way that non-point source pollution reaches local rivers, streams, and lakes.
Development has a major impact on our water resources by replacing natural ground cover with manmade, impervious surfaces. Low Impact Development (LID) is an innovative stormwater management approach that minimizes this impact. LID techniques focus on a specific site and can be applied to new as well as existing developments. These techniques are used to mimic a site’s pre-development hydrology by infiltrating, filtering, storing, evaporating, and detaining runoff close to its source. LID preserves the hydrologic cycle, protects drinking water quality & quantity, benefits fish & wildlife, reduces flooding & property damage, and saves communities money.
