Low Impact Development or LID is a stormwater management approach and site-design technique that emphasizes water infiltration, values water as a resource and promotes the use of natural systems to treat water runoff. Low impact development is a way to mimic the natural process and to avoid water pollution.
Low impact development approach employs distribution management techniques, called integrated management practices (IMPs). LID IMPs are used to satisfy storage and infiltration of stormwater.
Management practices that are suited to low impact development include:
The City of Owatonna was awarded a $500,000 Low Impact Development (LID) grant in June 2008 by the Minnesota Pollution Control Agency (MPCA). The grant will assist the city with development of stormwater management infrastructure designed to reduce the volume and rate of runoff and ultimately improve water quality.
The grant funds will be used to complete several LID projects in various locations throughout the city. The projects are designed to address flooding issues in the city and promote LID practices that will result in fewer problems in the future. The city has outlined the following objectives to implement LID practices:
