Low Impact Development Photo Database


Back Home Next Summary


Low Impact Development (LID) is a site design strategy that maintains or replicates predevelopment hydrology through runoff source control by reducing and disconnecting impervious areas, lengthening flow path and runoff time, and protecting sensitive features including: riparian buffers, wetlands, steep slopes and flood plains.

Examples of these structures include permeable pavement surfaces, grass buffers, porous landscape detention and green roofs. Urban Drainage and Flood Control District provides details on many LID structures in Volume 3 of the Drainage Criteria Manual under the 4-Step Process. http://www.udfcd.org/downloads/down_critmanual.htm

This photo essay has been compiled to show examples of LID structures in Colorado.

Major Storm Detention Structures

Although not runoff reduction or LID, detention BMPs displaying habitat and additional water quality benefits may be featured here.

This database is compiled and maintained by the CASFM Stormwater Quality Committee.  Please submit photos and summaries for other structures that may be added to this list. Also send additional information about existing structures in this database to Holly Piza at hpiza@udfcd.org.
