Urban Water Issues - Steve Rodie, Associate Professor, Agronomy and Horticulture, UNL

  1. 1. Steven N. Rodie, FASLA Assoc. Professor/Landscape Horticulture Specialist Department of Agronomy/Horticulture Department of Biology Landscape Architecture Program Environmental Studies Program University of Nebraska-Lincoln University of Nebraska at Omaha Changing Paradigms in Stormwater Management Implementing a Sustainable Future in Nebraska: Urban Water Issues September 25, 2013
  2. 2. Overview  Stormwater management – Why?  Sustainable stormwater management – How?  Changing the paradigm • Green Infrastructure • Low Impact Development (LID) • Best Management Practices (BMPs)
  3. 3. Why should stormwater be managed?  Water issues  Quantity (flooding, drought)  Quality (contaminants and temperature)  Stormwater regulations (Clean Water Act)  National Pollution Discharge Elimination System (NPDES) Permits - Phases I and II  Communities with Combined Sewer Overflows (CSO) Photo: University of Nebraska - Kearney Platte River Page
  4. 4. We All Live in a Watershed Graphic: Arkansas Watershed Advisory Group
  5. 5.  Omaha CSO Project  $1.66 billion (2011 Dollars); complete 2027  Avg. residential sewer rates to $50/mo. by 2017  Deep tunnel • 5.4 miles long, 170 ft. deep, 17 ft. diameter • 25% of project budget….can we make it smaller? http://www.epa.gov/heatisland/resources/pdf/WayeHotRunoff.pdf $$$
  6. 6. How is Stormwater Sustainably Managed?
  7. 7. Paradigm Shift Working with nature vs. controlling nature?
  8. 8. http://www.epa.gov/epaoswer/non-hw/green/pubs/asla-water.pdf
  9. 9. When I am working on a problem I never think about beauty. I only think about how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong. Designer, architect, author and visionary R. Buckminster Fuller
  10. 10. http://www.epa.gov/heatisland/resources/pdf/WayeHotRunoff.pdf Paradigm : “..a philosophical and theoretical framework of a scientific school or discipline…” Merriam Webster Online
  11. 11. Look deep into nature, and then you will understand everything better. Albert Einstein
  12. 12. Look Like Nature…..  Critical to understand client and public biases and expectation for natural landscape character  “Well-behaved” nature  physically possible?  potentially high maintenance and inputs  “Natural” nature – no maintenance typically not an option but not too much…..
  13. 13. Massing/Defined Edges Relatively Low Plants/Seasonal Interest
  14. 14. The Best Management Solution: 1)Don’t create impervious surfaces 2) If surfaces are created, reduce their coverage and/or imperviousness 3) See #1 above
  15. 15. Green Infrastructure is the interconnected network of open spaces and natural areas, such as greenways, wetlands, parks, forest preserves and native plant vegetation, that naturally manages stormwater, reduces flooding risk and improves water quality. (http://greenvalues.cnt.org/green-infrastructure)
  16. 16. Taken for granted as public benefits, ecosystem services (air and water purification, flood and climate regulation, biodiversity, scenic resources, etc.) lack a formal market and are traditionally absent from society’s balance sheet. As a result, their critical contributions are overlooked in public, corporate and individual decision-making. http://www.fs.fed.us/ecosystemservices/pdf/ecosystem-services.pdf
  17. 17. http://www.stormh2o.com/july-august-2006/green-stormwater-ecosystem.aspx
  18. 18. Low Impact Development (LID) is an innovative stormwater management approach …modeled after nature: manage rainfall at the source using uniformly distributed decentralized micro-scale controls. LID's goal is to mimic a site's predevelopment hydrology. http://greenvalues.cnt.org/green-infrastructure http://www.epa.gov/ne/topics/water/lid.html
  19. 19. http://www.swircd.org/pdf/conservation%20subdivision%20design%20handbook.pdf Low Impact Development
  20. 20. The EPA defines a storm water Best Management Practice as a "technique, measure or structural control that is used for a given set of conditions to manage the quantity and improve the quality of storm water runoff in the most cost-effective manner." http://www.safedrain.com/stormwater-bmp
  21. 21. Site: Omaha Sewer Maintenance Facility (68th and Q) Completion: Spring 2014 Funding, Design and Research: EPA ORD and Region 7; USGS; City of Omaha; Olsson & Assoc.; Felsburg Holt Ullevig; UNL Extension
  22. 22. Potential Benefits – Green Infrastructure and Low Impact Development Improve water quality runoff Lessen runoff quantities Lessen runoff time of concentration Add significant value to community landscape aesthetics Reduce infrastructure costs
  23. 23. Turning Potential Benefits into Real Benefits Green stormwater management must be Politically supported Client-embraced and understood Site-specific Well-designed Well-constructed Well-maintained
