1 Building Resilient Infrastructure for the 21 st Century 1 Maria Mehranian Cordoba Corporation & Los Angeles Regional Water Quality Control Board October 19, th Annual Lake Arrowhead Symposium: Resilient Cities & Regions

2 Building Resilient Infrastructure for the 21 st Century 2 Characteristics of a Resilient City Engine of self-organized responses and recovery methods Ability to absorb and rebound from catastrophic events as well as chronic stresses Awareness of interdependencies between diverse regional population groups, economic sectors & place types Agile governance approaches based on adaptive learning

3 Water Supply in California 3 In California, water is: in the WRONG amount at the WRONG time in the WRONG places

4 Water Supplies in California 4 Statewide conveyance systems Vast network of dams, reservoirs, and pumping stations Billions of dollars spent Over 100 years in the making Source: DEMIS Mapserver

5 Water Supplies in California 5 Northern California Wetter climate More rainfall Major urban areas 14.5M population 19% of California s electricity is consumed by water-related uses Central Valley Moderate climate Less rainfall Major agricultural center 6.5M population Southern California Arid climate Less rainfall Highly urbanized 22M population

10 Sources of Water in Southern California 1 0 Colorado River Aqueduct Completed in miles of canals, tunnels, and buried conduits 1.2M acre-feet per year 1/3 of Southern California s water supply

11 Sources of Water in Southern California State Water Project 1 1 Source: Long Beach Water Department

12 Sources of Water in Southern California 12 State Water Project System of water pumps, conveyance, and storage that distributes water from North to South Over 700 miles of canals, pipelines, and tunnels and 21 dams 2.4M acre-feet annual water delivery 1/3 of Southern California s water supply Provides water to 25 million people and 750,000 acres of agricultural land Single largest consumer of power in California

13 Sources of Water in Southern California Sacramento/San Joaquin Delta 13 Source: adammandelman.net

14 Sources of Water in Southern California 14 Sacramento/San Joaquin Delta Series of islands protected by dirt levees Home to 56 species Irrigates the Central Valley Provides 20% of the State s water supply Levees at severe risk from earthquakes and sea level rise Water moves in and out, with Delta acting as a vessel

16 Sources of Water in Southern California 16 Bay Delta Conservation Plan Benefits: Habitat restoration Improve resilience of Delta water supplies Improve native species populations Prevent saltwater intrusion Reduce risks for local communities Risks: High cost Long construction lead time Endanger the native species populations Ground water contamination Threat to economic vitality in local communities

17 Water Supplies at Risk 17 Every big project is risky, but what is the risk of doing nothing?

27 Water Resilience in California 27 California s water supply, infrastructure, and policy has proven rigid and unsustainable. To improve resilience, California needs: New, diverse, and sustainable sources New models of collaborative governance

28 Water Resilience in California 28 Potential new sources: Sacramento/San Joaquin Delta Restoration Construction of twin tunnels at new intakes in the Delta Local and regional storm water capture Water recycling Conservation Groundwater cleanup Desalination All of the above

29 Water Resilience in California 29 How do we pay for it?

30 Water Resilience in California Water Bond: Funding gets us going 30 $520M to improve water quality for beneficial use, for reducing and preventing drinking water contaminants, disadvantaged communities $1.495B for competitive grants for multi benefit ecosystem and watershed protection and restoration projects $810M for integrated regional water management plan projects $2.7B for water storage projects, dams and reservoirs $725M for water recycling and advanced water treatment technology $900M for projects to prevent or clean up the contamination of groundwater that serves as a source of drinking water $395M for statewide flood management projects and activities

31 Integrated Governance 31 Achieving a Sustainable Approach: working together gets us there

32 Example: Los Angeles MS4 Permit 32 Regulation as a tool to design sustainable water infrastructure Storm water cleanup is a requirement by law MS4 permit regulates the water quality New paradigm: recognizing that all water is precious A regional approach to storm water Storm water is the most cost effective water Improve water quality while creating sustainable water infrastructure Watershed management plans Enhanced watershed management plans Constitute BMPs and lead time to monitor

33 Example: Los Angeles MS4 Permit 33 From Sustainable Regulation to Resilient Infrastructure

34 Example: Elmer Street Project 34 From Sustainable Regulation to Sustainable Infrastructure

35 Example: Elmer Street Project 35

36 Example: Elmer Street Project 36 From Sustainable Regulation to Resilient Infrastructure Meets the Clean Water Act requirements Infiltrates 5.4 million gallons of storm water annually Improves water quality by reducing concentration of lead, copper and other solids Educates 300 visitors annually

37 Example: Los Angeles River 37 From Sustainable Regulation to Resilient Infrastructure

38 Example: Los Angeles River 38

39 Example: Los Angeles River 39 From Sustainable Regulation to Resilient Infrastructure 51 miles of river way currently used as flood control channel Navigable waterway hard bottom and soft bottom areas Receives discharge from industrial activities and all storm water and surface water from the cities it goes through Sustainable storm water regulation makes revitalization possible Revitalization plans include parkways, bikeways, bioswales, pocket parks, and storm water capture facilities

40 Water Policy: The California Experience 40 Previous approaches are no longer sustainable Balance environmental protection with social equity and economic prosperity More important now than ever before to meet water supply needs sustainably All sectors have a role to play We must all work together Source: wsdot.wa.gov
