Showcasing GIS Tools and Maps for Great Lakes Stormwater Workshop Cleveland, Ohio August 10, 2006 Kimberly Majerus FHWA-Resource Center Environmental Technical Services Team
Hydrology & water quality alteration – physical, chemical, biological Stormwater, Water Quality, NPDES, Soils, Erosion, Sediment, Drainage, Impacts To handle these various responsibilities – we need maps
Use of GIS & Technology – How do we get there?

GIS Tools & Data: Stormwater & Water Quality • Three Examples to Highlight: • Cleveland, OH Pilot Research for WatTrans GIS & Decision Support System (DSS) • NYSDOT mapping of drainage outfalls using GPS & GIS • PA Stormwater & Water Data on Web – at PA State GIS Clearinghouse
GIS-Based Decision Support System (DSS) - Ohio WatTrans Planning, Pilot Research for Cleveland area, OH • 3 components OH DSS Tool as: • GIS maps for project area -with viewer • DSS output (to consider potential effects in project area and watersheds and possible BMPs) • Links to more information using DSS as first step • Partners: USGS in OH, the Cuyahoga River Remedial Action Plan (RAP), USEPA, the Ohio Dept of Transportation, the Northeast Ohio Areawide Coordinating Agency and others.

Formula for Success: Using GIS for In-House and Contracted Work • Determine - how data and GIS to be used, by who • Measure benefits of GIS: before and after • Can focus on one topic but keep the door open for • integrated analyses and decisions
Formula for Success (cont): Using GIS for In-House and Contracted Work • Match scale & complexity to the decision • Include flexibility and scalability into tool • Pursue consistency in data development & delivery • Useful data is available and downloadable for free
