LID Design


LID Design Principles

LID design recognizes the value of the natural landscape and native vegetation. Protecting a site's sensitive natural features is central to LID planning and design. Therefore, a thorough site analysis prior to planning is critical. LID design capitalizes on the functions and aesthetics of the natural landscape - providing stormwater management solutions, along with aesthetic and recreational benefits for the community. Overall, LID principles focus on directing development to the most suitable areas on a site, while reducing the distance of runoff flow paths and managing stormwater as close to its source as possible.

Treatment Train
The concept of a treatment train uses multiple treatment devices prior to discharging to local streams and waterways so that the combined effect on water quality and runoff volume is more than each individual practice by itself.
