NPDES Phase II in Wake County: Forging A Collaborative Approach to Stormwater Management
APWA ConferenceSeptember 19, 2005
Background
Countywide Stormwater Management Study completed in August, 2005
Purpose - evaluate the programmatic, operational and funding options available for the development of a collaborative stormwater program within the County
Focused on water quality protection, flood prevention and compliance with regulatory mandates (Neuse Rule & NPDES II)
Stormwater Management Is An Integral Component of Providing Both High Quality of Life and Continued Economic Development to Our Community
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
Most Subwatersheds Have Been Degraded Or Impacted By Urbanization
The State Has Identified 93 Miles of Streams Throughout Wake County As “Not-Supporting” For Their Intended Uses
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
2002 303(d) List of Impaired Streams
These Conditions Will PersistAs Development Occurs in the
County
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
Water Supply Watershed Protection– Impacts 9 of the 13 jurisdictions
Sediment and Erosion Control– Required in every jurisdiction
Floodplain Management– Required in every jurisdiction

What Can We Do to Address These Environmental Issues and New Regulatory Requirements More Efficiently and Effectively in the
County?
The County Convened a Stormwater Focus Group to Evaluate the Feasibility of a Collaborative Stormwater Program Consultant facilitated process Representatives from all 13
jurisdictions participated 10 meetings were held between
November ’04 and June ’05 Developed recommendations
for a collaborativestormwater program tomeet common goals
Individual Needs Assessments Were Performed for Each Community
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
Stormwater Level of Service (LOS) Matrix
All Individual Stormwater Programs in the County Received a LOS Rating of “C” or Lower

The Focus Group Developed a Vision For Addressing Stormwater Management In Wake County:
Develop a collaborative program with voluntary participation to manage stormwater
Efficient and effective regulatory compliance
Consider the development ofa stable and dedicated sourceof funding
Implement appropriate environmental monitoring to assess effectiveness of program
To Achieve This Vision, We Propose ToMove Forward With Two Parallel Initiatives:
Initiative 1: Continue the Stormwater Managers Focus Group to develop/implement demonstration projects to build the foundation for future collaborative projects
Initiative 1 Collaborative Program Recommendations
1)Development of a county-wide environmental monitoring program
2)Development of a common GIS system for stormwater asset inventory
3)Development of a common ordinance and program for post-construction controls (including design manual)
4)Development of a countywide training program for selected
stormwater activities
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
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
Thank You For Your Time And Interest!
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 systemA LOS “F” program is non-responsive or
reactive while a LOS “A” program is pro-active
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
