LID Manual for Planners and Builders

Engineers and planners in northwest Ohio are interested in strategies for protecting water sources and other natural elements as they build or renovate. At a Best Land Use Practices workshop held in Toledo May 5, these professionals learned about Low Impact Development (LID) and saw examples of best management practices (BMPs).

Low Impact Development (LID) describes the use of swales, rain gardens, and other natural environmental elements to capture, hold, and treat stormwater close to where it falls. In practice, LID can range from preserving and restoring natural features to building retention ponds, installing riparian green strips, green roofs, and other structural elements into new site development and redevelopment projects.

Several free books and manuals address these practices, including TMACOG’s Stormwater Management Standards Manual. Another tool is a LID manual that has been developed by the conservation group American Rivers. At the June 17 meeting of the Stormwater Coalition, committee members are expected to announce their endorsement of the LID manual. American Rivers says that the manual is technical guide, designed to provide stormwater managers and site designers with a common understanding of LID goals and objectives, site assessment considerations, and a toolbox of stormwater best management practices applicable to the Lower Maumee and Ottawa River watersheds. The manual (large PDF) is online.
