Low Impact Development saves development costs.
LID utilizes a system of source controls and small-scale, decentralized treatment practices to help maintain a hydrologically functional landscape. The conservation of open space, the reduction of impervious surfaces, and the use of small-scale storm water controls, such as bioretention, are just a few of the LID practices that can help maintain predevelopment hydrological conditions.
At one 80-acre development in Prince George’s County, Maryland consisting of 199 homes on 10,000-square-foot lots, LID was used by the developer, which saved money:
• Eliminated storm water ponds by using bioretention, saving approximately $300,000;
• Gained six additional lots; and
• Reduced finished lot cost by approximately $4,000.
