Standards Manual for Rhode Island outlining LID, a process by which development is designed to fit the landscape, not vice versa.
The new Rhode Island Stormwater Design and Installation Standards Manual changes stormwater management to include more creative planning and site design as well as better engineering practices in keeping with the requirements of the Smart Development for a Cleaner Bay Act of 2007. The new manual requires Low Impact Development (LID) for all sites, representing a fundamental shift in how development projects are planned and designed. LID is a more comprehensive approach to managing stormwater that uses site planning and design techniques that store, infiltrate, evaporate, and detain runoff as close as possible to the point where precipitation reaches the ground. LID can be used to accommodate growth while reducing the environmental impact of site development. Many of the LID concepts employ non-structural on-site treatment that can reduce the cost of infrastructure while maintaining or even increasing the value of the property relative to conventionally-designed developments. In the past the landscape was altered significantly to fit the style of development, whereas this LID process is reversed so that development is designed to fit the landscape and its natural features.
