Municipal and County Collaboration on Stormwater Management & Water Quality Programs

Presentation to Wake County Board of Commissioners on August 15, 2005, discussing the need for a collaborative stormwater program to address water quality protection, flood prevention, and regulatory compliance. The presentation highlights the impact of urbanization on subwatersheds, the identification of impaired streams in the county, and the responsibility of local government staff to maintain compliance with state and federal regulations. The proposed initiatives include the development of a county-wide environmental monitoring program, a common GIS system for stormwater asset inventory, a common ordinance and program for post-construction controls, and a countywide training program for selected stormwater activities.

  1. Municipal and County Collaboration on Stormwater Management & Water Quality ProgramsPresentation to Wake County Board of CommissionersAugust 15, 2005

  2. Background • Countywide Stormwater Management Study initiated in November 2004, completed August, 2005 • Purpose - evaluate the programmatic, operational and funding options available for the development of a collaborative stormwater program • Focused on water quality protection, flood prevention and compliance with regulatory mandates (Neuse Rule & NPDES II)

  3. Stormwater Management Is An Integral Component of Providing Both High Quality of Life and Continued Economic Development to Our Community

  4. Stormwater Management Spans Many Issues that Affect Quality of Life and Economic Growth: • Flooding • Public safety • Insurance costs • Development costs • Water Quality • Drinking water • Recreation • TMDL Avoidance • Stream Condition • Aesthetic value • Public safety • Habitat

  5. Most Subwatersheds Have Been Degraded Or Impacted By Urbanization

  6. Approximately 47 percent of streams were monitored by the State 28 percent of all monitored streams were impaired 2 named streams have been added in the 2004 303(d) update The State Has Identified 93 Miles of Streams Throughout Wake County As “Not-Supporting” For Their Intended Uses 2002 303(d) List of Impaired Streams These Conditions Will Persist As Development Occurs in the County

  7. Local Government Staff Are Responsible for Maintaining Compliance with Several State and Federal Regulatory Programs • Neuse River Nutrient Sensitive Waters Strategy (i.e. “Neuse Rules”) • Raleigh, Cary, Garner and Wake County are designated communities • Water Supply Watershed Protection • Impacts 9 of the 13 jurisdictions • Sediment and Erosion Control • Required in every jurisdiction • Floodplain Management • Required in every jurisdiction

  8. Many Jurisdictions Will Soon Fall Under the NPDES Phase II Regulations

  9. What Can We Do to Address These Environmental Issues and New Regulatory Requirements More Efficiently and Effectively in the County?

  10. Why Does Wake County Need a Collaborative Stormwater Management Program? • Environmental concerns are important to the citizens of Wake County • Citizens desired a higher level of service when presented with a choice in Raleigh • Must responsibly balance growthand environmental protection • Must overcome staff andfunding limitations tomeet regulatory requirementsand citizen’s expectations forlevel of service

  11. The County Convened a Stormwater Focus Group to Evaluate the Feasibility of a Collaborative Stormwater Program • Representatives from all 13 jurisdictions participated in the process • 10 meetings were held between November ’04 and June ’05 • Provided information for an Individual Needs Assessment (INA) of their program • Developed recommendationsfor a collaborativestormwater program tomeet common goals

  12. Individual Needs Assessments Were Performed for Each Community

  13. Stormwater Management’s Three Functional Areas • Stormwater Program Management • The planning and management of assets, including compliance with state and federal regulations • Operations and Maintenance • Efforts to maintain collection system assets to ensure that they operate at peak efficiency • Capital Improvements Project (CIP) • The construction of new assets to upgrade older portions of the system to meet desired Level of Service

  14. Stormwater Level of Service (LOS) Matrix

  15. All Individual Stormwater Programs in the County Received a LOS Rating of “C” or Lower A “C” Level of Service rating has not been sufficient to prevent our streams and watersheds from continuing to experience impacts due to uncontrolled stormwater runoff

  16. A Decreasing Level of Service F Level of Service Will Decrease Over Time if Existing Resources Remain Constant Constant Funding Funding Time

  17. The Focus Group Developed a Vision For Addressing Stormwater Management In Wake County: • Develop a collaborative program with voluntary participation to manage stormwater • Efficiently and effectively achieves regulatory requirements • Consider the development ofa stable and dedicated sourceof funding • Implement appropriate environmental monitoring to assess effectiveness of program

  18. To Achieve This Vision, We Propose ToMove Forward With Two Parallel Initiatives: • Initiative 1: Continue the Stormwater Managers Focus Group to develop/implement programs • Selection and implementation of demonstration projects to build the foundation for future collaborative projects

  19. Initiative 1 Collaborative Program Recommendations • Development of a county-wide environmental monitoring program • Development of a common GIS system for stormwater asset inventory • Development of a common ordinance and program for post-construction controls (including design manual) • Development of a countywide training program for selected stormwater activities

  20. Initiative 2 - Creation of a Countywide Stormwater Management Task Force • Comprised of citizens from each of the participating jurisdictions • Task force will build on the efforts of this study and will consider feasibility issues

  21. Task Force Activities: • Detailed review of the recommendations from the first phase of the project • Cost/benefit evaluation for recommended programs • Identify citizen expectations for stormwater level of service • Develop funding recommendations • Develop an implementation plan

  22. Action Requested • That the Board of Commissioner’s authorize its Chairman to send a letter to each of the municipalities requesting that they appoint two citizens to serve on the Countywide Stormwater Management Task Force.

  23. Thank You For Your Time And Interest!

  24. Each Jurisdiction Was Assigned a Level of Service (LOS) rating of A F for Three Key Components of Stormwater Management • Stormwater Program Management • The planning and management of assets associated with stormwater, including compliance with state and federal regulatory requirements • Operations and Maintenance • The management of stormwater assets to assure that the assets continue to operate at peak efficiency • Capital Improvements Project (CIP) • The construction of new assets that upgrade older portions of the stormwater system and that handle growth within the system A LOS “F” program is non-responsive or reactive while a LOS “A” program is pro-active
