2/10/10 - Kent State Intergovernmental Collaboration Forum - Stark County Storm Water Collaboration

  1. 1. “Sustain a Greener Ohio” Storm Water Conveyance Systems Inventory A Multi - Jurisdictional Collaboration……. 2 0 0 9 - 2 0 1 4 Sean J. Phillips, GISP GIS Coordinator Stark County Regional Planning Commission
  2. 2. What is NPDES ? NPDES is an acronym that stands for National Pollution Discharge Elimination System. In response to the 1987 Amendments to the Clean Water Act (CWA), the U.S. Environmental Protection Agency (EPA) developed Phase I of the NPDES Storm Water Program in 1990. NPDES Phase I required permits for the discharge of storm water to waters of the state from: - Medium and large municipal separate storm sewer systems (MS4s) located in incorporated places or counties with populations of 100,000 or more; - Eleven categories of industrial activity which includes construction activity that disturbs five or more acres of land.
  3. 3. NPDES Phase II The Phase II Final Rule, published in the Federal Register on December 8, 1999, requires NPDES permit coverage for storm water discharges from: Certain regulated small municipal separate storm sewer systems (MS4s); and construction activity disturbing between 1 and 5 acres of land NPDES Phase II MS4 permits require small municipalities to develop a program to implement 6 Minimum Control Measures: 1 - Public Education and Outreach 2 - Public Participation and Involvement 3 - Illicit Discharge Detection and Elimination 4 - Construction Site Runoff Control 5 - Post-Construction Runoff Control 6 - Pollution Prevention and Good Housekeeping
  4. 4. NPDES Phase II 3 - Illicit Discharge Detection and Elimination b. You shall develop, if not already completed, a comprehensive storm sewer system map, showing the location of all outfalls and the names and location of all surface waters of the State that receive discharges from those outfalls. Within five years of when your coverage under this general permit was granted, your comprehensive storm sewer system map shall also include your MS4 system (owned and/or operated by you), including catch basins, pipes, ditches, flood control facilities (retention/detention ponds), post-construction water quality BMPs and private post-construction water quality BMPs which have been installed to satisfy Ohio EPA’s NPDES Construction Storm Water general permit and/or your local post-construction water quality BMP requirements. If you will be unable to develop your comprehensive storm sewer system map during this permit term, you shall provide an alternative schedule to complete with your 2009 Annual Report.
  5. 5. Collaboration: Why?…. EPA – Unfunded Mandate The EPA mandated that the mapping be completed but did not mandate the method.... One Countywide succinct layer vs. non-collaboration…. Project cost: Collaboration vs. Single Entity - Personnel, equipment and software: PC’s, GPS field unit, mapping software and vehicle, maintenance, administrative costs. Cost of each MS4 District completing separately: Almost $1.5 Million Cost of project with 9 MS4 Districts collaborating: $617,727 Savings $880,000 +
  6. 6. Collaboration: Getting Started…. Preliminary work: Knew EPA was going to announce additional mapping requirements in early 2009…….. Pilot area: City of North Canton – May of 2008 - Use of Interns/Co-ops - Sample storm water data sets: determine approximate number of catch basins, manhole covers and pipes per mile. Fall of 2008 through Spring 2009 Letters of interest / participation – 13 MS4 Districts Prospectus of project sent out Question / Comment period
  7. 7. Collaboration: The next step…. Spring 2009 through Summer 2009 GIS Consortium formed – 6 Townships, 3 Cities Meetings, Meetings, Meetings Memorandum of Understanding signed Summer 2009 through Fall 2009 Hire personnel: 1 FT GIS Technician, 3 Interns Acquire hardware and software Training
  8. 8. GIS Consortium Map ….
  9. 9. Storm Water Inventory …. Kick-off meeting in October 2009 Commenced structure inventory mapping on November 1st Project to be finished by December of 2013. Due to EPA by February of 2014. Timetable: How do we track? Created Grid map of all MS4 Districts. Project number of grids to be finished by end of each calendar year. 417 Total grids Appoximately 45 grids have various levels of inventory finished.
  10. 10. Storm Water Inventory ….
  11. 11. Storm Water Inventory …. Goal: One Storm water GIS layer for entire county EPA requires only location ( x and y coordinates) Our data models include many attributes: - Elevation - Material - Condition - Pipe Size - Many more………… Future use of data set: Service Improvements Flow models Complete additional attribute fields Inventory Maintenance
  12. 12. Collaboration: Insights…. What have we learned from our experience? Stay focused: Long road from inception to implementation Benefits: Tangible? Make sure collaborators understand how the finished product will benefit their entity. Promote proactive decision making, rather than reactive. Replicable? Yes !!!! Collaboration in Stark County: Sparked additional projects Complete GDB model available Prospectus available
