1 Showcasing GIS Tools and Maps for Great Lakes Stormwater Workshop Cleveland, Ohio August 10, 2006 Kimberly Majerus FHWA-Resource Center Environmental Technical Services Team

2 Stormwater, Water Quality, NPDES, Soils, Erosion, Sediment, Drainage, Impacts Hydrology & water quality alteration – physical, chemical, biological To handle these various responsibilities – we need maps

3 Step One: Identify Users & User Needs Select Existing Data & Tools & Eval Need for New Ones Deliver Solutions & Tools & Measure Benefits Assess Data Needs and Scale (spatial & temporal) Life Cycle to Match User Needs Identify Available Data, Methods, Tools & also Gaps Use of GIS & Technology – How do we get there? Technology Life Cycle to Match User Needs Design & Develop Data and Tools & Maintenance Plan

4 National Spatial Data Infrastructure Local Data & Uses County/Parish Regional & National Share & Use- Free GIS Map Data at Various Levels

5 Free GIS Data to Download from the Web (Great Lakes states listed, from National Spatial Data Infrastructure (NSDI)) Spatial GIS Data Online Web Clearinghouses: NATIONWIDE SOURCES (NSDI) ILLINOIS INDIANA MICHIGAN MINNESOTA NEW YORK OHIO PENNSYLVANIA WISCONSIN

6 Remote Sensing – Free Orthophotographs Geographically referenced to the earth (black/white or color of various scales) Presence of: Impervious surfaces? Water bodies? Drainage patterns? Comp storage? New Cooperative Effort: Imagery for the Nation Free from Web at IL Geospatial Data Clearinghouse, IDOT as partner

7 GIS, Tools, Data, and Methods Example Study - use of Free Data from the web (floodplains, streams, orthos, elev, soils, trans, + more) National Spatial Data Infrastructure (www.geo-one-stop.gov)

8 Free Map Data: U.S. Hydrologic Units (USGS) (watersheds)

9 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

10 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.

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

12 NYSDOT SPDES Outfall Mapping- example computer screen More than 4000 drainage outfalls have been mapped using GPS and GIS

13 Power Tools-Spatial Analysis: GIS -what no other tool can do IL GIS Predictive Modeling and Tools for Impact Assessment, Mitigation and Monitoring after construction GIS Model Simulations: Baseline “before” construction KkkKKKKKKkkKKKKK Predicted Model Results: “After” construction Proposed Trans

14 Throughout Project Delivery- use Data & Tools Project Delivery Cycle: Planning, Studies, Drainage, Design, Construction, O&M Environmental Approvals, Commitments, and Monitoring

15 GIS, Tools, and Data Factors for Success (next pages to read as handout For Great Lakes workshop)

16 Step One: Identify Users & User Needs Select Existing Data & Tools & Eval Need for New Ones Deliver Solutions & Tools & Measure Benefits Assess Data Needs and Scale (spatial & temporal) Life Cycle to Match User Needs Identify Available Data, Methods, Tools & also Gaps Use of GIS & Technology – How do we get there? Technology Life Cycle to Match User Needs Design & Develop Data and Tools & Maintenance Plan

17 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

18 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
