1 Supplemental SWMP and BMP Development Melissa M. Long, PE Fall Seminar 2017

2 SPECIFIC GOAL NPDES Annual Report NEW GOAL MS4 Management and Administration Through SWMP MAIN GOAL Water Quality Measuring compliance has historically been through the annual reporting of activities. Effectiveness of SWMP was measured through annual Water Quality Reporting

3 Current Drainage System Improvements Prioritization The Stormwater Utility, established in 2008, provides the City s Funding for operation, maintenance and improvements By Ordinance E, the City shall Annually allocate minimum funding as follows: Drainage System Rehabilitation DSR $6 million Capital Improvement Projects MSMP $4 million or 15% of the Stormwater Utility Revenue (greater value) 3

4 Drainage System Rehabilitation DSR Component The focus is on deteriorated drainage systems that require improvements to meet their original operation. DSR Improvements into two (2) categories: Restoration/Repair requiring very limited Design Restoration/Repair requiring Design 4

5 Capital Improvement Projects MSMP Component Public Works revised the Master Stormwater Management Plan MSMP mapped and modeled its entire drainage system. supports multiple elements of the City s SWMP needs that included an Evaluated challenged drainage system City-wide identified potential drainage improvement projects. This model is used to prioritize and recommend CIP Projects. 5

6 Capital Improvement Projects MSMP Component (cont.) Projects are Prioritized with the following Ranking Criteria: o Flood Control Improvements (40% of Score) Structure Flooding - 50% of value Arterial Road Flooding - 30% of value Local Road Flooding - 20% of value o Operation & Maintenance Improvements (20% of Score) reduce velocities (eliminate scour & sediment transport) o Surface Water Quality Improvements (40% of Score) Nitrogen Reductions 6

12 Apply resources in a manner that helps you attain water quality through effective implementation and update of your practices NPDES Annual Report MS4 Management and Administration SWMP Effectiveness Assessment Water Quality

13 PLANS, SOPs, AND REPORTS PERMIT REQUIREMENTS TOOLS AND DATABASES Your SWMP describes how you operate and maintain your MS4, implement ordinances and authorities to manage stormwater in manner that complies with the permit and in theory improve water quality. Your Assessment Program needs to demonstrate that you are effectively applying your resources and standards

14 Begin with the Goal in Mind

15

16 4 step process Monitoring Identify Focus Areas Review/Update Current Water Quality Monitoring Assessment Define Key Performance Indicators Focus resources and SWMP practices and resources

17 Key Performance Indicators Track load reductions achieved through Capital Improvement & Retrofit Projects Septic Tank Phase Out Structural Control Inspection follow-up Maintenance Activities & Initiatives Load Reduction through Operations Street Sweeping Roadway Litter Removal Inlet & Closed Conveyance Cleaning BMP Effectiveness

18 PRIORITIZE ACTIVITES WITHIN FOCUS AREAS Structural Control Inspections Proactive IDDE Maintenance Initiatives Stakeholder Roles Annual Measure Key Performance Indicators Address SWMP Weaknesses

19 Surface Water Quality is a City-Wide Responsibility Your Effectiveness Assessment Program needs to help you meet the long term goal water quality improvement. Your Annual Assessment Report needs to communicate that you are implementing your SWMP to the Maximum Extent Practicable.

22 Complexity Kills Productivity LEVERAGE WHAT YOU HAVE Improve based on results

23 Work Order Dashboard A complex analysis using Power BI.

24 Annual SWMP Effectiveness Reporting Results to Date Summary of the water quality monitoring for reporting year Stormwater pollutant loading changes during the year being reported Annual EMC calculation tied to reporting period rainfall (comparative benchmark) Analysis Water quality Trend Summary Stormwater pollutant load reduction achieved through projects, Routine maintenance activities, Structural Control Inspections Illicit Discharge and other water quality inspection & Enforcement Actions Water Quality Monitoring Program Implementation Sampling frequency changes Monitoring location changes

25 Year 3 SWMP Effectiveness Report Determination of whether loads are increasing or decreasing If pollutant loads are increasing, changes may need to be considered Resource Allocation Practices & Procedures Ordinances & Authorities EMC calculated load using average annual rainfall for the period C3Y4 through C4YR3

26 Year 4 SWMP Effectiveness Report Identification of areas needing corrective action and an implementation time table Summary evaluation of the SWMP s effectiveness in reducing pollutant loadings from the MS4 Description of whether stormwater pollutant loadings discharged from the MS4 have decreased Results and annual loadings from Part V (Monitoring Requirements) should be included. Recommended SWMP revisions for each of the elements in NPDES Annual Report Part III Identification of areas that should be targeted for corrective actions and a corresponding timeframe. Retrofit projects Structural BMPs new construction and/or rehabilitation/expansion Maintenance initiatives
