Inventory and Prioritization of LID Projects at a Sub-Watershed Scale

Retrofitting existing sites to remove stormwater from the sewer systems and reintroduce stormwater to vegetation and soils is critical to the restoration and revitalization of our urban watersheds. It is a goal of the City of Portland's Bureau of Environmental Services to integrate Low Impact Development (LID) concepts into existing urban development to realize broad based goals for watershed health and community livability. Beyond just being an alternative to piped solutions, LID projects realize multiple benefits such as neighborhood beautification, removal of impervious surfaces, restoration of the tree canopy, heat island reduction, groundwater recharge, safe pedestrian crossings, and traffic calming.
