8 Four Horsemen of the Apocalypse..the herd is growing Climate Change Reduced Water from Delta Colorado River Import Reductions Reduced Groundwater Recharge

9 SPRAWL: The Number One Threat to Water Sustainability "According to the US EPA, damage to water quantity and quality will grow dramatically unless sprawl is brought under control."

10 Current urbanization practices are not sustainable: prime farmland is threatened by water scarcity.

11 Energy Cost will drive policy

17 What do we want? Healthy Drinking Water!

18 We want Healthy Fisheries

19 Swimmable Rivers

20 Productive Ag

21 Water Wise Landscape

22 1 The Santa Ana River Watershed is a hydrologic whole 2 Working in concert with nature is cost effective 3 See each problem as interrelated, seek efficiencies and synergies

23 1 As citizens of the Watershed, create solutions 2 No ONE person can do it alone 3 Think Big!

24 1 OWOW is a shared Vision for the Watershed 2 Breakthrough innovations 3 Create a Water Ethic

25 Watershed Level Thinking Beneficial Use Assurance Multi-Hazard Preparation Natural Resources Stewardship Energy and Environmental Impact Response Land Use Planning Water use efficiency Water Resource Optimization Operational Efficiency and Water Transfers Disadvantaged and Tribal Community Government Partnerships

27 Sprinklers gone wild

28 Water Budget-Based Rate Structure Est. Cost $0-50/AF Additional 10% Water Savings 150,000 AF/yr

29 Water budget-based rates Incentives to water agencies to implement new water rate systems Benefits: Water demand reduction by all water users Provides information on how to use water more efficiently Help create a new water ethic

30 Efficient Water Use Guidebook/Program customized for the watershed Water use efficiency Smart irrigation Education and outreach Public tools Purpose: Provide information on how to use water more efficiently Provide simple tools Help create a new water ethic

32 Santa Ana River Hydrologic System Nature s Treatment Train

33 Interruptions to Natural Treatment Train

34 Solution Concepts Watershed Habitat Conservation Plan Forest First Program Energy Use Reduction Program Water Banking Transfer Off-River Urban Runoff Storage Management Multi-Use Flood Control Transportation Corridor Projects Brine Management River Sediment Transport Water Use Efficiency Program

35 Forest First Program Projects Protection of headwaters Increased yield Protection of recharge areas Sediment control water quality Reduced flood hazards Removal of invasive species Recreational opportunities Savings in avoided infrastructure (e.g. reduced treatment requirements)

36 Forest First

37 Forest First

38 Maximize use of rain water Provide flood control capacity

39 Operational Efficiency and Water Transfers

40 Water Banking Transfer Projects Reduce dependency on imported water Groundwater storage Conjunctive use Stormwater capture and recharge Indirect potable reuse Use of river for water conveyance Increased resilience to interruption of imported supplies (e.g. earthquake)

41 Avg. Cost $ /AF Additional 5% Water Savings 75,000 AF/yr

42 Reliable source of regular supply Low comparative energy costs Accessible to most urban communities More sustainable than other alternative water sources

43 Recycled Water Cascading down the Santa Ana River Watershed Wastewater is recycled and reused 2-3 times before discharge to ocean Low pumping cost as flows and use move downstream

44 Regional Land Use Planning Guidebook Incorporate low-impact development (LID) practices Stormwater management to: Reduce pollution Use water as a resource Reduce impact to pre-development hydrology Purpose of Guidebook: A tool to incorporate water principles into land use general plans Multi-jurisdictional outreach effort

45 Multi-Use Flood Control Corridor Projects Streams and tributaries of Santa Ana River and the river itself Enhanced recharge Rubber dams Detention facilities Soft-bottom Stormwater in combination with recycled or imported water Native riparian vegetation and habitat Recreational use Water quality and TMDL s Adaptation to climate change impacts

46 Off-River Storage Projects and Supply Credits Collect water within floodplain or adjacent to it Groundwater replenishment Stormwater capture and recharge Water quality improvements Natural habitat

47 Regional Urban Runoff Management Fund As an alternative to comply with LID requirements and to support implementation of regional treatment projects Benefits may include: Water quality improvements Stream restoration Habitat Groundwater recharge

48 Transportation Corridor Stormwater Capture and Treatment Projects Water use efficiency changes in landscape irrigation Stormwater capture and recharge Water quality improvements

49 Santa Ana River Sediment Transport Implementation of measures to assure sediment to appropriately transferred along the entire Santa Ana River system Benefits may include: Increased recharge Restoral coastal and beach habitat Reduce operation and maintenance costs

50 Modified Watershed Brine Management System Salt removal Water quality improvements Alllow development of new supplies (e.g. groundwater desalination, reuse) Enhanced groundwater storage

51 Water Industry Energy Use Reduction Incentive Program Reduction of greenhouse gas emissions Reduced operational costs Help compliance with AB32

52 Regional Habitat Conservation Gap Planning Regional habitat conservation plans allows participants to implement land use decisions consistent with a plan without project-by-project review and case-by-case permitting by the resource agencies Benefits may include: Streamlined permitting approach Greater certainty Habitat interconnection Species and habitat preservation

53 It s time to catch up with the rest of the world

54 Bright Spots/Early Adopters in the watershed Budget-allocation water rates 8% reduction in water use achieved GWRS provides 70 mgd of highly-treated water for groundwater replenishment Modified flood retention basins for stormwater capture and groundwater recharge Water and energy self-sufficiency goals Capture water behind Seven Oaks Dam for conservation and enhance groundwater recharge downstream Multi-partner Garden Friendly Program to encourage water-efficient landscape

55 Cumulative Benefit of Expanded Watershed Water Supply Development 775,000 AFY 300,000 Acre Foot per Year 250, , , ,000 50,000 0 Water Efficient Irrigation New and Retrofit Recycled Water Tiered Allocation Rates Groundwater Desalination Stormwater Capture

56 The promise of OWOW is water for people, fish and food.
