LID Checklist (pdf, xls): An easy-to-use LID Checklist includes over 250 best practices that might be implemented during each project phase.
Precipitation Maps: Precipitation maps detail the depth of a storm event in a 24-hour period, and are needed in modeling to tailor an LID facility design to its location.
Infiltration Testing Fact Sheet (pdf): Geared toward municipalities and more advanced practitioners, this fact sheet offers detailed information on multiple testing methods.
LID Infiltration Facility Calculator (xls): Size vegetated facilities including rain gardens, stormwater planters, and vegetated swales with check dams without using complicated proprietary modeling software. Download the model and read about it or watch a tutorial video on how to enter data and interpret results.
GIS & Data Mapping Tool: A customized planning tool for a handful of Oregon's basins to help identify natural conditions and provide suitability maps for locating LID facilities.
Runoff Reduction Tool: A customized planning tool to estimate runoff before and after development.
Information Resources: This page provides additional resources to help identify conditions important to deciding what kind of LID facility may be used and where. Topics include floodplains, wetlands, riparian areas & buffers, habitat areas, septic systems, contaminated soils & groundwater, landslides, wellhead protection areas, drinking wells, vertical separation, and horizontal setbacks.
