Low Impact Development News

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.

While LID techniques in Colorado have emphasized passive runoff of reduction and infiltration techniques that mimic predevelopment hydrology, recently there have been discussions about allowing precipitation capture, harvesting and reuse. This has traditionally required a water right. Please see Senate Bill 08-119 – A BILL FOR AN ACT CONCERNING A LIMITED EXEMPTION FOR WATER COLLECTED FROM RESIDENTIAL ROOFTOPS for details and the additional newspaper articles linked below to monitor the progress of this bill.
