Stormwater runoff is a serious threat to streams, rivers, and the bay. Water quality is affected as stormwater carries sediment from upland erosion, nutrients from agricultural and residential fertilizers, and pollutants such as heavy metals and petrolium from roadways. Water quantity is also affected. As development progresses and more land is covered by impervious surfaces less water is able to infiltrate into the ground. There is less groundwater recharge and more surfacewater runoff. The volume of water running off the land overfills storm sewers, floods the landscape, and deepens and widens streams.
Our approach to stormwater management utilizes stormwater ponds, wetlands, and bioretention facilities to capture and treat stormwater runoff before it enteres our waterways. Wetlands are natural sponges that hold great quantities of water, filter sediments, uptake nutrients, and slowly release the captured water into the groundwater and into the atmosphere through transpiration and evaporation.
