Stormwater, Water Quality, NPDES, Soils, Erosion, Sediment, Drainage, Impacts

Hydrology & water quality alteration –

physical, chemical, biological

To handle these various responsibilities – we need maps

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:1. GIS maps for project area -with viewer

2. DSS output (to consider potential effects in project area and watersheds and possible BMPs)

3. 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.

NYSDOT Drainage Outfall Mapping for State Pollutant Discharge Elimination System (SPDES)

NYSDOT SPDES Outfall Mapping- example computer screen

More than 4000 drainage outfallshave been mapped using GPS and GIS

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
