  1. WVDOTGeospatial Transportation Information Section MS4 Storm Water Inventory Project

  2. Program Planning & Administration Division Geospatial Transportation Information (GTI) Section Highway Data Services Unit GIS Unit - Geospatial Data Management -Geospatial Services • Roadway Inventory Log • -Roadway Statistics • -Public Certified Mileage

  3. MS4 Project Background • Updates to the Clean Water Act required additional attention to pollution from storm water • Water Pollution Control Permit with WVDEP • Requires Storm Water Inventory Map • Requires regular inspections

  4. WVDOH Districts and Municipal Separate Storm Sewer Systems (MS4) MS4 Areas defined by 2000 Census Urbanized Areas

  5. Project Background • Environmental Coordinators in each District Office given task of meeting permit requirements. • Several independent • projects were started. • No standard methods or • data items.

  6. GTI Involvement • It was determined that GIS would offer the best solution to meet the requirements. • The GTI Section • was brought on • to assist in project • development.

  7. Project Development • Standards • Common format and Attributes • Coordinate System • Collection Methods • Processing Methods

  8. Project Development • Trimble Juno with • Terrasync field data • collection software • was chosen. • Two purchased for • each district.

  9. Data Dictionary

  10. Field Procedures

  11. Post-Processing Procedures

  12. Rating Systems • Features evaluated on two rating systems • MS4 environmental rating • Maintenance rating

  13. District Workflow • Utilize GIS map to plan field work • Collect GPS data • Post-Process GPS data • Submit Shapefiles to GTI • District Environmental Coordinators conduct follow up procedures on inspection results. • MS4 Features are inspected every 3 years.

  14. GIS Workflow • Shared project folder created on server for moving data • Exported shapefiles and pictures from districts moved to the shared folder • Data quality is verified • Shapefiles are loaded into MS4 Feature Class in SDE • ArcGIS Server Map Service • Pictures loaded to web server

  15. Project Status • Pilot project was conducted in one district to verify procedures. • Summer interns are utilized for field work • 5,000 features collected the first summer • 9,000 features collected the following summer • About 85% of all MS4 areas have been inventoried • The remaining 15% are in two districts with the largest urbanized areas • Other districts will be conducting inspections this year

  16. Interactive Map http://gis.wvdot.com/MS4/MS4.html

  17. Future • Testing currently underway to deploy the project as ArcGIS Mobile Application to simplify the inspection process. • Enhancement of the web map to allow district environmental coordinators to edit attributes.

  18. Spinoff Projects • Pipe/Culvert inventory in non-ms4 areas • Small Bridge inventory • Rail Crossing inventory • Land Slide inventory

  19. MS4 Stormwater Inventory • Questions? • Kyle Weatherholt • (304) 558-7434 • Kyle.S.Weatherholt@wv.gov
