OSU Extension CatalogOne of the first steps in siting a low-impact development facility is infiltration testing. Infiltration tests estimate the rate at which runoff will infiltrate, or pass through, native soil. An infiltration test, in essence, involves digging a hole, pouring in water, and measuring the drop in water...
Online ResourceThe goal of the Well Water Program is to help Oregonians protect the groundwater that supplies their drinking water through education. Information available at Well Water Events is now available for your use on this OSU web page.
OSU Extension CatalogPorous pavement allows runoff to move through the surface and into the soil beneath, reducing the volume of stormwater. Learn about porous asphalt, pervious concrete, permeable pavers and flexible paving systems and how each variation of porous pavement can substitute for conventional, impervious...
OSU Extension CatalogA water-quality swale is like a rain garden in motion: It treats runoff while simultaneously moving it from one place to another. Water-quality swales are channeled depressions planted with trees, shrubs and grasses that help remove pollutants from stormwater. Learn about two different kinds of...
OSU Extension CatalogVegetated filter strips are a stormwater management system designed to slow the speed of runoff, filter pollutants, and collect sediment. Learn design considerations and planting options for these low-maintenance, relatively inexpensive filtering facilities.
OSU Extension CatalogA rain garden doesn't "grow" rain, but it does provide an attractive, effective way to manage runoff. Learn what it takes to make your own rain garden.
OSU Extension CatalogSoakage trenches are a space-saving way to manage runoff while preserving aesthetics at a site, but developers should plan for significant costs to build and maintain them. Learn more about how to use soakage trenches as part of the low-impact development toolbox.
OSU Extension CatalogGrowing a garden on your roof is an attractive alternative building method, but there's a lot to know before you start hauling soil to the top floor. Learn how vegetated roofs, also known as "green" roofs, can play an elevated role in the low-impact development landscape.
OSU Extension CatalogA drywell is a vertical, underground system that receives runoff via buried pipes. Learn when and how to use a drywell to help manage stormwater in the low-impact landscape.
