This document summarizes a presentation on an updated regional water facilities master plan. It outlines near-term and long-term water supply and conveyance projects to address constraints and risks identified in supply/demand and storage utilization analyses through 2025 and beyond. Near-term projects focus on untreated water conveyance and operational flexibility. Long-term projects include a second crossover pipeline, Pipeline 6, Colorado River conveyance, and Camp Pendleton desalination. It recommends Board approval of proposed near-term projects and distribution of the initial master plan draft for review.

 Supply/Demand scenario planning has provided a reasonable range of demands on Aqueduct System  No Supply/Demand Gaps under Normal Weather ◦ Dependent on member agencies achieving conservation and local supply targets  Supply/Demand Gaps will occur under Multi-Dry Year Weather and MWD water shortage allocation ◦ Frequency of dry-weather occurrence ◦ Magnitude of dry-weather shortfall 4

 Developed evaluation metrics and performance thresholds ◦ Provided basis for new conveyance capacity and supplies ◦ Identified frequency and magnitude of maximum facility utilization and supply shortages ◦ Planned around acceptable risk levels  Conveyance risks increase by 2020 ◦ Untreated capacity constraints ◦ New infrastructure needed between 2020 - 2025  Supply shortage risks increase beyond 2025 o Compounded with lower levels of local supplies and conservation 5

2014 – 2025 Project Budgets Total Existing CIP (all projects) 1 $2,961M Potential Deferrals of Long-Term Projects beyond 2025 2 ($653M) Deleted Service Connections ($20M) Potential Long-Term Project Evaluations 3 $3.5M to $4.5M Potential Re-scoping of Near-Term Projects ($8M) to $62M Proposed New Near –Term Projects 4 $40M to $60M Revised Total CIP (all projects) $2,344M to $2,434M Net Change to 2014-2025 CIP Budget ($546M) to ($637M) 7 1. Total CIP is $3.1 billion and includes expenditures beyond 2025. 2. Defers portion of Pipeline 6 and Second Crossover Pipeline beyond 2025. 3. Includes Camp Pendleton Desalination and Colorado River feasibility evaluations. 4. Includes system isolation valves and portion of P3/P4 Conversion Project south of delivery point. Estimate for total project ranges between $200-$220M.

Near-Term Projects (2014-2025)  Address untreated water conveyance constraints ◦ South County ◦ MWD Delivery Point  Improve operational flexibility to optimize existing assets  Defer ~$700 million in CIP expenditures beyond 2025  Revise scope and timing of existing projects (budgeted at $150 million) in current CIP 8

Project Purpose Time Frame Second Crossover Pipeline Address untreated water delivery constraint s/o Twin Oaks 2035+ Pipeline 6 * Address untreated water delivery constraint at MWD delivery point 2035+ 9 Long Term Projects (Beyond 2025) Project Purpose Time Frame Colorado River Conveyance * Convey QSA supply through a CWA-owned facility 2035+ Camp Pendleton Desalination * Address potential regional supply shortages 2025+ Beyond 2025 – Mutually Exclusive Options to Pipeline 6 * Implementation of a project would preclude other options.

10

Long-Term Projects (beyond 2025)  Adaptive management strategy for long-term supply projects ◦ Monitor local and imported water supply development per 2010 UWMP Scenario Planning ◦ Monitor water demand trends and achievement of GPCD targets ◦ Monitor other regional and statewide water issues affecting long-term supply options ◦ Provide staff direction on continuing to develop long-term options  Colorado River Conveyance  Camp Pendleton Desalination ◦ Determine implementation of facilities based on needs and cost efficiencies 10

 Avoid duplicative reconsideration of broad policies, alternatives, and program wide mitigation measures  Provide a more exhaustive consideration of regional effects than would be practical in a project specific EIR  Provide the basis for determining whether a subsequent activity may have new effects which had not been considered before  Allow reduction in paperwork 12
