  1. Clean Water Integrated Plan Spokane River Forum March 26, 2013

  2. The Next Phase Water Quality + Innovation + Regulation + Finances = Opportunity

  3. The Opportunity • Largest infrastructure investment in City’s history • Balance environmental & financial constraints • Responsible use of the public’s money • Add stormwater • Allow innovation • Leverage our investment into better neighborhoods, a better City, a healthier economy

  4. Integrated Plan • WET WEATHER • Discharges to the River • Stormwater and CSO • COMPREHENSIVE SOLUTION • Regulatory requirement • Stakeholder engagement • Best value for our investment

  5. The Plan’s Goals • We want a cleaner River faster. • Prioritize work that has a greater impact on pollutants. • We want to implement cost-effective and innovative technologies. • Add “green” technologies. • We want holistic integration with other critical infrastructure. • Solve multiple problems • Better streets, new water mains, better parks…

  6. Cleaner River Faster • Prioritize by greatest reduction of pollutants • Volume versus frequency • Adding Stormwater • Initial look: • Removing prioritizing stormwater greater pollutant reduction over smaller CSO basin for: • TSS • Heavy metals • Even phosphorus

  7. The Method • Design Criteria • Basin Prioritization • Right-sizing CSO storage • Green solutions • Alternatives strategies

  8. Structured Decision Criteria • Methodical selection process • Ranking based on goals • Policy maker and project team interface • Communication with stakeholders MODA Multiple objective decision analysis

  9. Decision Criteria • GOAL: Decide upon the best mix of CSO and stormwater projects that will remove as many pollutant as rapidly as possible with the highest additional public benefit at the lowest long-term life cycle cost. • Criteria: • System benefits and risks • Environmental outcomes • Community outcomes • Operations & maintenance considerations • Life cycle costs

  10. Basin Prioritization Accelerate work in 3 basins that have the greatest impact. • THE BIG 3 • CSO Basin 26 • CSO Basin 34 • COCHRAN STORMWATER BASIN

  11. Next Steps--Prioritize: • Remaining CSO Basins • Large Stormwater Basins

  12. Status-BIG 3: CSO Basin 34 • Constructing two tanks in 2013 • Evaluating remaining storage needs

  13. Status-BIG 3: CSO Basin 26 • Preliminary design • Evaluating sites

  14. Status-BIG : Cochran Basin Evaluating projects Analyzing flow

  15. Right-sizing CSO Storage One overflow per year based on a 20-year moving average

  16. Innovative & Holistic • Integrate: • Streets • Parks • Water • Wastewater • Sidewalks • Ped / Bike • Golf Courses • Greenways • Street Trees • We want to implement cost-effective and innovative technologies. • We want holistic integration with other critical infrastructure

  17. Timeline • Deliver plan by December 2013 • Construct BIG 3 by 2017 • AND as many more basins as we can Today 2017 Deliver Integrated Plan Dec. 2013

  18. More to come Thank you!
