  1. Latest Developments -Effectiveness Assessment and Research Priorities Geoff Brosseau California Stormwater Quality Association (CASQA) December 4, 2007

  2. Presentation Outline • California Stormwater Quality Association • Assessing Program Effectiveness • Research Priorities

  3. California Stormwater Quality Association • 1989 - Founded as the Stormwater Quality Task Force – official technical advisory body to State Water Board • 2003 - Nonprofit public benefit 501(c)(3) corporation • Professional member association dedicated to the advancement of stormwater quality management through: • collaboration, • education, • regulatory review, • implementation guidance, • and scientific assessment. • Specific purpose is to assist those entities charged with stormwater quality management responsibilities with the development and implementation of stormwater quality goals and programs • Practitioners of stormwater quality management • Technical focus

  4. Collaboration / Education / Implementation guidance / Scientific assessment • Meetings • General Membership meetings (1991- ) • Workshops (BMP Handbooks, ASBS) • Conferences (2005- ) • Guidance • BMP Handbooks (3/93 and 1/03) • Retail Gasoline Outlet (RGO) BMP Guide (3/97) • Construction Stormwater Sampling & Analysis Guidance (10/01) • Effectiveness Assessment White Paper (10/05) • Resource Library – Public education materials (12/05) • Stormwater Monitoring and Research Priorities (3/07) • Effectiveness Assessment Manual (5/07)

  5. Assessing Program Effectiveness

  6. Measuring Effectiveness • What impact is my program having? • What is changing as a result of my program?

  7. Survey says… • Need for guidance on how to measure effectiveness of stormwater programs • CASQA response • White paper on effectiveness assessment • Guidance document

  8. CASQA Guidance Document • Introduction • Effectiveness Assessment Overview • Strategies for Assessing Effectiveness • Methods for Assessing Effectiveness • Fact Sheets for Program Elements • Water Quality & Overall Program Assessment

  9. Iterative Program Management & Evaluation STEP #1 PLANNING STEP #2 PROGRAM MODIFICATION IMPLEMENTATION STEP # 3a IMPLEMENTATION ASSESSMENT INTEGRATION STEP # 3b WATER QUALITY ASSESSMENT

  10. Identifying Outcome Levels

  11. Municipal Program Effectiveness Assessment Assessment Outcome Levels Level 6 – Protecting Receiving Water Quality Increasing Difficulty Level 5 – Improving Runoff Quality Level 4 – Reducing Loads from Sources Level 3 – Changing Behavior Level 2 – Raising Awareness Level 1 – Documenting Stormwater Program Activities

  12. Attributes of Assessment Method • Assess • Effort (Outcome Level 1) • Achievement (Outcome Levels 2 - 6) • Type • Narrative or qualitative • Numeric or quantifiable • Progress • Effort  Achievement • Qualitative  Numeric or quantifiable

  13. Challenges to measuring stormwater program effectiveness (Cause –? Effect)(Action –? Outcome) • Degrees of separation phenomenon • Complicating effects of integrating all inputs • Outcome Level is defined by: • Type of BMP being measured • Power of BMP

  14. Implementation Success Story: Pesticides and Stormwater In 1998, using Clean Water Act authority, California Water Boards and USEPA: • listed waterbodies in virtually every urbanized area of California as impaired by pesticides and toxicity • required that TMDLs (Total Maximum Daily Loads) be calculated and that dischargers (local governments) reduce the amount of these pesticides in the waterbodies to the TMDL targets (max. allowable amount)

  15. Implementation Success Story: Pesticides and Stormwater (cont’) • In 2000 – USEPA announces the phase out of diazinon products • By 2002 – the amount of reported diazinon applications has decreased substantially • By 2006 – Aquatic toxicity and diazinon concentrations in urban creeks have decreased dramatically – in many cases below TMDL targets

  16. Diazinon are levels dropping quickly and significantly

  17. Implementation Success Story: Pesticides and Stormwater • By 2006 – Aquatic toxicity and diazinon concentrations in urban creeks have decreased dramatically – in many cases below TMDL targets - Level 6 Outcome – Protecting receiving water quality • USEPA and DPR changing the way pesticides are regulated to address/prevent water quality problems / Retailer data show less-toxic product sales ↑ - Level 3 Outcome – Changing behavior • Surveys - Level 2 Outcome – Raising awareness

  18. Municipal Program Effectiveness Assessment Assessment Outcome Levels Level 6 – Protecting Receiving Water Quality Increasing Difficulty Level 5 – Improving Runoff Quality Level 4 – Reducing Loads from Sources Level 3 – Changing Behavior Level 2 – Raising Awareness Level 1 – Documenting Stormwater Program Activities

  19. Research Priorities

  20. Project Tasks • Survey and review projects conducted by research organizations • Organize and compile relevant stormwater research projects • Conduct CASQA members survey and finalize results • Update research priorities list and prepare research concept descriptions

  21. Studies by Sponsoring Organization 316 project descriptions in database Includes 28 ongoing or planned (Caltrans)

  22. Research Topics and Subtopics

  23. Research Topics and Sub-Topics, cont’d

  24. Studies by Research Topic

  25. Member Survey Survey requested information on Prioritization of research sub-topics Specific research questions Recent research project descriptions

  26. 13 Respondents Cities of Davis, Downey, Monterey, San Diego Fresno Metropolitan Flood Control District Lawrence Livermore National Laboratory Caltrans CSU Sacramento 5 Consultants 1 Anonymous

  27. Survey Rankings by Topic

  28. Priority Research Projects 31 research projects developed that addressed related priority research areas, as shown in next slide

  29. Priority Projects by Relative Rank

  30. Detailed Project Descriptions for Top 10 Priority Projects Problem statement Project objectives Proposed tasks Estimated budget range Short list of relevant publications Relevant recent or ongoing studies from surveyed research organizations

  31. Recommended Future Work We received additional suggestions on research organizations that could be surveyed in future Develop an online stormwater research project database for CASQA (currently in development by Geosyntec), that members can search for relevant research, and obtain reports, papers, and contact researchers

  32. Next Steps for CASQA • Continue to populate the database with ongoing projects and update research needs • CASQA committees will consider research needs to update their work focus • CASQA may look for member agencies to partner on complete research and potentially partner with others
