LID Fact Sheets

  Rain gardens, like conventional landscapes, can have an array of aesthetics and still function well.

The fact sheets offer an overview of the siting, design, construction, and operations & maintenance of LID facilities.

The relationship of LID to the Oregon Department of Environmental Quality's (ODEQ) Underground Injection Control (UIC) permitting process is likely to be of special interest to municipalities and designers who want to use these practices; included in the discussion is how an LID facility may intentionally or accidentally become a UIC and strategies to avoid creating a UIC.

Infiltration testing is crucial to decision making in the planning phase and sizing infiltration facilities cannot be done without it.   Green streets can be integrated with other transportation infrastructure to create a beautiful streetscape.
