2nd Public Meeting - Options March 30, 2010 Agenda Overview of Water Issues What is a WIRP? Purpose of WIRP Evaluation Process WIRP Objectives Options Brainstorming Initial Categories of Options Closing Sources of Water Supply Local Groundwater 35% Imported Water from MWD* 65% * MWD - Metropolitan Water District Overview of Water Issues State Water Project Colorado River Aqueduct Local Other Imported Water Issues MWD Water Costs • In 2009, full service water rates increased 15% (3 times the previous year’s increase) • Over next five years, MWD expects annual double-digit rate increases • Bay-Delta solution is expected to cost billions for MWD alone Climate Change • California DWR estimates that future climate change could reduce SWP supplies statewide by as much as 15% by 2030 Source Water Quality Groundwater Pumped from the Raymond Basin Contamination issues Declining groundwater levels Reduced pumping rights by 20% Water Integrated Resources Plan IRP Definition “Comprehensive approach to evaluating supply-side & demand-side resource alternatives with respect to explicitly defined & often conflicting objectives.” AWWA, 1994 Main features: Open and participatory decision process Planning scenarios that consider changing conditions Consideration of institutional context 9 IRP’s in relation to other plans Strategic Planning (IRP’s; conceptual analysis; policylevel planning; examining trade-off among resource alternatives) UWMP (Urban Water Management Plan required by State every 5 years; compares demand and supply only) Master Planning (Capital Improvement Plans, detailed facility studies, operational analysis) Prelim Design (Environmental Impact Review, Project Implementation) Mission Statement The Pasadena Water Integrated Resources Plan will provide an achievable, long-term strategy to meet current and future water needs. The goals of the WIRP are to sustainably and cost-effectively address local and regional water supply and demand issues, reflect community values, and adapt to changing conditions. Evaluation Process Portfolio Analyses Supply & Demand Options (building blocks) Build Portfolios (using themes) Raw Performance Score Card Rank Portfolios Define Planning Objectives & Performance Measures Refine Analysis Preferred Strategy WIRP Objectives Provide a reliable water supply Maintain affordability, while addressing fairness and equity Ensure safe, high-quality drinking water Protect source waters and the environment Protect cultural and recreational resources Maximize efficiency of water use Maintain quality of life and positive economic climate Reduce risk and maximize opportunities Ensure public safety Reduce energy footprint for water operations Status Quo Approach Water Supply How vulnerable to climate change, what impact on water quality, how much does this cost Imported Water Existing Groundwater Planning Horizon Growth Neutral New Conservation Imported Water Existing Groundwater New Local Supplies New Conservation Imported Water New Local Supply Existing Groundwater Ideas from st 1 Public Meeting Reduce percentage or portion of water used for landscaping – currently 50-70 overall Incentivize water conservation with energy nexus Real time notification to customers on water usage Have landlords provide water efficient fixtures, motivate/implement tenant conservation Educate people about irrigation and runoff – soil types/swales, etc. Encourage more efficient irrigation, e.g. drip Convert turf areas Partner with large educational institutions, landscape changes/public education opportunity – new paradigm Landscaping contests, free landscaping to winners, etc. Explore integration of reclaimed water into City’s supply Capture what we throw away – sinks, showers, etc. Look at greywater systems Evaluate water catchments for rainwater, e.g. natural depressions Identify areas that are more suitable for groundwater recharge – consider zoning tools to protect and maximize recharge Incentivize/rebates for redesign of sites to capture more runoff Reduce imperviousness, reasonable but meaningful X % per year Encourage new development to store runoff on site Partner with other resource agencies to develop options that might otherwise be too expensive, e.g. solar for desal Conservation/ Demand Management Recycled Graywater On-site stormwater capture/ Porous pavement Ocean Desalination Partnership
