StormWater Assessment and Management decision-support Process

Funded by the Cooperative Institute for Coastal and Estuarine Environmental Technology, the SWAMP project is an open-source, web-based tool designed to assist local governments and developers in streamlining adoption of low-impact development (LID) practices. The SWAMP project created tools that were completed in December, 2010, and it also funded several focus group workshops with potential end-users in coastal and southwest areas of Oregon. Upon completion of the project, we have been integrating these tools into this Stormwater Solutions website. We are also using current grant funding from Oregon Department of Environmental Quality to expand this project to the Mid and Upper Willamette Valley to support the LID Academy project.

The SWAMP project included the creation of the following tools:

  • ArcGIS data gathering and mapping tool
  • Runoff Reduction Calculator - A decision-support tool that helps the user predict stormwater runoff from an area, before and after development, and decide on various LID practices to reduce the runoff to pre-development conditions.
  • Vegetaion Infiltration Calculator (Rain Garden Calculator) - a design tool to help size infiltration facilties
  • LID Fact Sheets with design sheets
  • Plant list for stormwater facilities
  • Model Documentation and Technical Guide
  • References and Publications
