Explain why the proposed project does not adversely affect any river afforded protection pursuant to the California or Federal Wild and Scenic Rivers Act. See section 6003(a)(1)(I) of the regulations.

The Pacheco Reservoir Expansion Project would expand the existing Pacheco Reservoir, which is located on the North Fork of Pacheco Creek. Pacheco Creek is a tributary to the Pajaro River which enters the Pacific Ocean through Monterey Bay. Other main tributaries of the Pajaro River include the San Benito River and Corralitos, Uvas, Llagas, and Santa Ana Creeks. The Pajaro River and its tributaries, including Pacheco Creek, are not listed as designated rivers in the California Wild and Scenic Rivers Act or the Federal Wild and Scenic Rivers Act. Therefore, the proposed project does not adversely affect any river afforded protection in the California Wild and Scenic Rivers Act or the Federal Wild and Scenic Rivers Act pursuant to 16 U.S. Code Chapter 28 Section 1271 et seq, or California Public Resources Code Section 5093.50 et seq., respectively, as required by Water Code Sections 79711(e) and 79751 (a).

Q.5:

Is the applicant an agricultural or urban water supplier as defined in section 6001 of the Program regulations? If not, enter “Not Applicable”; if so, has the applicant submitted complete Agricultural or Urban Water Management Plans to DWR? Have those plans been verified as complete by DWR? If not, explain how the applicant is working towards compliance with the requirements of Water Code section 10608.56. See section 6003(a)(1)(J) of the regulations.

The Santa Clara Valley Water District, the project applicant, is an urban water supplier, as defined by Section 6001 of the California Code of Regulations. The California Department of Water Resources (DWR) categorizes the Santa Clara Valley Water District as a water wholesaler. The Santa Clara Valley Water District submitted its 2015 Urban Water Management Plan (UWMP) to the DWR on June 20, 2016. DWR has verified that the 2015 UWMP is complete and complies with California Water Code. The Santa Clara Valley Water District is not an agricultural water supplier, as defined by Section 6001 of the California Code of Regulations, and is therefore not required to complete an Agricultural Water Management Plan.

Q.6:

Does the proposed project affect groundwater basins, as defined by Water Code section 10722 et seq.? If not, enter “Not Applicable”; if so, identify the affected groundwater basins and describe how the project would be integrated with future GSP(s). Explain how the project would reduce, eliminate, or have an effect on undesirable results (as defined in regulations section 6001(a)(85)) within the affected groundwater basin(s). Describe how the applicant would work with GSA(s) or adjudicated participants of the basin. See regulations section 6003(a)(1)(K).

The Pacheco Reservoir Expansion Project (Project) has the potential to provide positive contributions in four California groundwater basins that are subject to the Sustainable Groundwater Management Act of 2014. The California Department of Water Resources (DWR) Bulletin 118 basins that could directly benefit from the Project include: Santa Clara Valley, Gilroy-Hollister Valley, Corralitos, and San Joaquin Valley. These basins contain medium or high priority subbasins, as defined by DWR's California Statewide Groundwater Elevation Monitoring (CASGEM) program. The Santa Clara Valley Water District (SCVWD) intends to enter into voluntary coordination agreements with each Groundwater Sustainability Agency (GSA) that could be affected by the Project. The Project provides direct benefits to seven high or medium priority CASGEM subbasins including: - Santa Clara Subbasin (medium priority) of the Santa Clara Valley Basin - Llagas Area (high priority), Bolsa Area (medium priority), Hollister Area (medium priority), and the San Juan Bautista Area (medium priority) of the Gilroy-Hollister Valley Basin - Pajaro Valley (high priority) of the Corralitos Basin - Delta-Mendota Subbasin (high priority) of the

Page 6: Proposal Full View - California · PDF file15.08.2017 · Project Proposal Objective* ... Explain why the proposed project does not adversely affect any river afforded protection pursuant

San Joaquin Valley Basin Groundwater sustainability management in these basins are led by four agencies: SCVWD, San Benito County Water District (SBCWD), Pajaro Valley Water Management Agency (PVWMA), and Grassland Water District/Grassland Resource Conservation District (GWD/GRCD). These agencies have filed with DWR as the exclusive GSAs for areas that underlie their jurisdictional boundaries. Involvement of GWD/GRCD presumes Reclamation will accept SCVWD?s request that the Incremental Level 4 refuge water supplies it provides will be delivered to GWD/GRCD. Groundwater benefits provided to refuge lands, however, would be similar regardless of the area Reclamation decides to provide Incremental Level 4 waters. The Project provides each GSA with opportunities to develop actions in their respective Groundwater Sustainability Plans to address undesirable results as defined in Water Code Section 10721. In subbasins underlying SCVWD service areas, additional surface water supplies developed through the Project can provide in-lieu groundwater recharge, and raise groundwater levels. For example, in the Santa Clara Subbasin, the Project would increase groundwater storage levels by 4 percent during critical years (2070 future conditions). In the Gilroy-Hollister Valley Basin, the Project would provide landowners near Pacheco Creek reliable supplies of high-quality groundwater in-lieu of delivered surface water, which could allow SBCWD to re-prioritize surface water deliveries to areas dependent on groundwater. In the Pajaro Valley, the Project may provide for continued in-channel groundwater recharge in the reach of the Pajaro River between Chittenden and Murphy Crossing. In the GWD/RCD, the delivery of Incremental Level 4 refuge water supply in below normal water years can, in part, reduce reliance on groundwater pumping. To accomplish these potential benefits, SCVWD intends to work collaboratively with each GSA in the respective subbasin. The SCVWD and SBCWD have executed a Memorandum of Understanding for preparation of a shared Groundwater Sustainability Plan (GSP) for the Hollister and San Juan Bautista subbasins. The SCVWD intends to enter into voluntary coordination agreements with PVWMA and GWD/GRCD to assist with incorporation of the Project into each agency's respective GSP. Related activities could include: exchange of data (geologic, hydrologic, etc.); establishment of consistent methods and assumptions applicable to the conveyance and delivery of water supplies; and further identification of Project benefits in supporting sustainable groundwater management and avoiding undesirable results.

Q.1 Flood Control Benefits: If the proposed project is not claiming flood control benefits, leave the following questions blank.

If applicable, how will the project provide flood control benefits? If some project operations will be for flood control purposes, explain. Are the flood control benefits realized locally and/or throughout the larger flood control system? (TR section 4.9.2.1) Describe any negative impacts of providing the flood control benefit. (TR section 4.9.2.4)

The Pacheco Reservoir Expansion Project (Project) will provide flood control benefits by reducing flows in Pacheco Creek downstream from the reservoir during flood events; however, the Project will not be operated specifically for flood control purposes. An HEC-HMS hydrologic model of Pacheco Reservoir was run to simulate the reservoir beginning at maximum operational storage (140,000 acre-feet, at an elevation of 694 feet), meaning that the benefits shown below will be available for all reservoir conditions. The model results show that, even though it will not be operated specifically for flood control, an expanded Pacheco Reservoir will always have capacity available to reduce flood flows significantly downstream from the new dam. A summary of the modeling results include the following: - 100-year flood: Pacheco Creek inflow of 7,565 cubic feet per second (cfs) reduced to 3,192 cfs (4,373 cfs or 61% flow reduction) - 50-year flood: Inflow of 6,828 cfs reduced to 2,779 cfs (4,049 cfs or 59% flow reduction) - 20-year flood: Inflow of 5,511 cfs reduced to 2,078 cfs (3,433 cfs or 62% flow reduction) - 10-year flood: Inflow of 4,203 cfs reduced to 1,430 cfs (2,773 cfs or 66% flow reduction) The Project will also provide incidental flood control benefits by further reducing downstream flows during flood events, when additional storage is available in Pacheco Reservoir. Santa Clara Valley Water District?s Water Evaluation and Planning (WEAP) model was run for proposed operations of Pacheco Reservoir for current conditions (2017), 2030 future conditions, and 2070 future conditions. The WEAP model results show that Pacheco Reservoir will have more than 1,000 acre-feet of available storage volume during some winter months (November to April), reducing flows in Pacheco Creek by 10 percent during a 100-year flood event. The 10 percent reduction in flood flows is expected to occur 80 percent of the time under current conditions (2017), 91 percent of the time during 2030 future conditions, and 96 percent of the time during 2070 future conditions. The combination of permanent and incidental flood benefits would reduce the flows downstream from the Project by around 4,700 cfs for the 100-year, return-period flood. WSIP Technical Reference Section 4.9.2.1 states that ?providing local flood control benefits could potentially cause flood control impacts at the system-wide level, and vice versa.? The Project?s primary flood control benefits will likely be realized locally, and positively impacting areas downstream of Pacheco Reservoir. It is expected that the reduction in flood flows will extend from the expanded reservoir, approximately 26 miles west along Pacheco Creek, to San Felipe Lake and the ephemeral Soap Lake area. Flood control impacts at a system-wide level have not yet been modeled; however, Project impacts beyond San Felipe and Soap Lakes would likely be reduced due to those lakes? storage effects. There are no anticipated negative impacts of providing the Project?s flood control benefits.

Q.2Flood Control Benefits: If the proposed project is not claiming flood control benefits, leave the following questions blank.

What methods were used to calculate flood damage reduction? Identify which of the following methods was used to quantify physical flood control benefits:

1.Modeling provided with feasibility study

2.New modeling using historical flood events or historical hydrology

3.New modeling using the climate change hydrology data set provided

If 1 or 2 is used, explain how benefits might be different under the provided future climate and sea levels projections. Provide justification for any methods not identified in section 5.4.3 of the TR. See also regulations section 6004(a)(1)(F).

Pursuant to Section 6004(a)(1)(F), the following methods were used to quantify physical flood control benefits for the Pacheco Reservoir Expansion Project: new modeling using historical flood events or historical hydrology (Method 2), and new modeling incorporating the climate change hydrology by the CWC (Method 3). A combination of Method 2 and Method 3 were used to determine the monthly available storage in the expanded Pacheco Reservoir for current conditions (2017), 2030 future conditions, and 2070 future conditions. Method 2 was used to develop the input for the current conditions (2017) modeling. New modeling, using CWC-provided climate change hydrology data (Method 3), was used for 2030 and 2070 future conditions modeling. Method 2 was used to estimate the physical flood control benefits. Historical hydrology records, from USGS gages on Pacheco Creek near Dunneville, California, and the Pajaro River at Chittenden, were analyzed using Bulletin 17B methodology to determine flood frequency flows at both gage sites. Flood flows for Pacheco Creek at the proposed dam site were estimated to be 45 percent of the flows in Pacheco Creek at Dunneville, based on the ratio of watershed areas. This ratio, coupled with the flood peaks generated by the flood frequency analysis (Bulletin 17B), was used to create design storms based on the December 1955 Dunneville flood. The design storms were used as input to an HEC-HMS hydrologic model of Pacheco Reservoir. The model was used to route the flood through the reservoir, beginning with a full pool, with the following results: - 100-year flood: Inflow of 7,565 cfs reduced to 3,192 cfs outflow (61% reduction in outflow) - 50-year flood: Inflow of 6,828 cfs reduced to 2,779 cfs (59% reduction in outflow) - 20-year flood: Inflow of 5,511 cfs reduced to 2,078 cfs (62% reduction in outflow) - 10-year flood: Inflow of 4,203 cfs reduced to 1,430 cfs (66% reduction in outflow) Based on these results, the Project is expected to reduce flood events by over 50 percent in all design storm scenarios. Incidental flood benefits were also calculated using SCVWDs WEAP model to determine the percentage of time that unused storage would be available in Pacheco Reservoir, from November through April, thereby increasing the capability of the reservoir to reduce flood flows. Downstream flood benefits were then determined by subtracting the flow reductions at the reservoir from the peak flows at Dunneville. The Dunneville rating curve was used to determine lower flood stages. The hydrologic analyses (WEAP and HEC-HMS) described above show that the Project will significantly reduce flood levels in Pacheco Creek at the USGS Dunneville gage. These estimated reductions are as follows: - 100-year flood: Reduced flood levels in Pacheco Creek by 4.3 feet - 50-year flood: Reduced 3.8 feet - 20-year flood: Reduced 3.3 feet - 10-year flood: Reduced 3.1 feet Flood benefits from the Project will not be affected by sea level rise because of the elevation of the areas where the benefits are projected to occur. The CWC VIC climate change data was used to develop the WEAP models for 2030 and 2070 future conditions. While there are indications that extreme flood-producing storms may increase as a result of climate change, there is no accepted methodology for quantifying that increase. Thus, for the flood benefits analysis for Pacheco Creek, climate change was used in the development of the reservoir operations

models, but historic hydrology was used for the flood hydrology analysis. The methods used to determine flood benefits described above are not identified in section 5.4.3 of the TR. Although the Project provides flood benefits, these benefits are not being monetized. Thus the methods described in section 5.4.3 of the TR do not apply. The modeling and hydrologic analyses clearly indicate that the Project will provide flood control benefits by significantly reducing flood levels in Pacheco Creek.

A.1 Flood Control Benefits: If the proposed project is not claiming flood control benefits, leave the following questions blank.

Attach any relevant flood damage reduction supporting documentation, such as hydraulic and hydrologic modeling studies, and property flood damage analysis (TR section 4.9.4). If information to support this question is located in another attachment, provide the location.

Q.1 Emergency Response Benefits: If the proposed project is not claiming emergency response benefits, leave the following questions blank.

If applicable, how will the project be operated to provide emergency response benefits? Identify the types of emergency benefits the proposed project could provide. (TR section 4.11.1). If additional information to support this question is located in another attachment, provide the location.

Pursuant to Section 6004(a)(3) of the California Code of Regulations, the Pacheco Reservoir Expansion Project (Project) would provide emergency response benefits to Santa Clara Valley Water District (SCVWD) service areas, including the Silicon Valley. Consistent with WSIP TR Section 4.11.2, the Project would provide the following emergency response benefits: - Delta levee failures, accidents, or acts of terrorism that impact Delta water supply operations (monetized benefit under public benefits - emergency response) - Earthquake events that impact local or regional water supply operations (monetized benefit under public benefits - emergency response) - Drought emergencies (monetized benefit under non-public benefits - M&I water supply) - Wildland Fire Emergencies (not monetized) Emergency response benefits are increased water supplies available to SCVWD that can be delivered in the event of an emergency. Emergencies may include major levee failures in the Delta, which would significantly degrade water quality, or a major earthquake that would disrupt the ability of SCVWD to import water into their service area. In such cases, the additional water supplies available in SCVWD surface reservoirs and groundwater storage developed through the Project, and the operational integration of the Project with SCVWD water system facilities, would help reduce or mitigate the impacts of emergencies. SCVWD?s WEAP model was used to estimate the amount of water that could be available for emergency purposes. This estimated quantity of water supply was based upon the long-term average increase in storage within surface reservoirs and groundwater basins. During an emergency response event, up to 100 percent of increased supplies would be made available. The operation of an expanded Pacheco Reservoir for emergency purposes would depend on hydrologic conditions and Pacheco Reservoir storage conditions. During normal Pacheco Reservoir operations releases to the Pacheco Conduit to meet SCVWD water demands would be discontinued in the event that reservoir storage volumes fall below 55,000 acre-feet. This ensures that flows and water temperatures in Pacheco Creek are maintained in consecutive dry year to support SCCC steelhead habitat. During an emergency operation, if SCVWD's Board of Directors determines a supply interruption to be an imminent risk to essential public health and safety, SCVWD may proceed with an emergency drawdown of Pacheco Reservoir below 55 TAF to meet SCVWD water demands. Such emergency circumstances

would include: - Delta export outage: Water exported from the Delta accounts for approximately 45 percent of SCVWD?s water supply. Accordingly, no or limited pumping at CVP and SWP export facilities due to natural or other events would significantly affect SCVWD?s ability to meet M&I water demands. - Imported water conveyance outage: Water imported from the CVP, SWP and SFPUC Hetch Hetchy accounts for approximately 60 percent of SCVWDs water supply. Outages of conveyance facilities (i.e., tunnels, pipelines, canals, pump stations) due to natural events, equipment failures, or other causes would limit SCVWD?s ability to meet water demands. - Other major events: This includes other major events, such as regional infrastructure failures or extended drought periods, that may occur when waters supplies are required to meet essential health and safety needs for drinking; hygiene and sanitation; fire protection; and/or to avoid permanent land subsidence due to groundwater depletion.

Section : BENEFIT CALCULATION, MONETIZATION, and RESILIENCY

BENEFITCALCULATION,MONETIZATION,andRESILIENCY

Q.1:

Did the applicant use the model products and assumptions described in section 6004(a)(1) of the regulations? See regulations section 6003(a)(1)(CC). If no, provide a description of the models and assumptions used to determine the without-project future conditions for years 2030 and 2070.

Modeling and analyses of without- and with-Project conditions for the Pacheco Reservoir Expansion Project (Project) utilized the model products and assumptions described in Section 6004(a)(1). The operational analyses for the Project are based upon the CWC-provided CalSim II model, as well as SCVWD WEAP model, and the Pacheco Creek Steelhead Habitat Suitability model (PCSHS). As the expansion of Pacheco Reservoir would not change Delta conditions (i.e., inflows, outflows, Delta pumping, X2), DSM II was not applied for this application. The CalSim II models for 2030 and 2070 (provided by the CWC and described in Section 6004(a)(1)) were used to model future without-Project conditions in 2030 and 2070. In addition, a WEAP model was used to simulate SCVWD system operations, as this system is not included in CalSim II. The WEAP model simulated SCVWD supplies, demands, reservoir and other system operations, local watershed runoff, and groundwater. The WEAP model incorporated CWC-provided climate change data, and followed CWC WSIP guidance on defining the projects to be incorporated into the without-Project future conditions, population, and water demands. The climate change input data for WEAP was prepared using CWC-provided surface runoff data for 1995, 2030 and 2070, by calculating surface runoff in 14 watersheds that comprise or drain into the SCVWD system. To synchronize the SCVWD operations in the WEAP model with the CalSim II 2030 and 2070 models, storage at San Luis Reservoir, along with CVP and SWP allocations from CalSim-II, were used as inputs to the WEAP model. To define future without-Project fisheries? habitat conditions, the PCSHS model was applied, and incorporated air temperatures from CWC-provided climate change data. CalSim II, WEAP, and PCSHS model simulations were also performed for without-Project current conditions (2017). The SWP 2015 Delivery Capability Report CalSim II model was used as the basis for developing the current conditions (2017) CalSim II run. However, two changes were incorporated into CalSim II: (1) San Joaquin River Restoration Program (SJRRP) flows were changed from full Restoration Flows to Interim Restoration Flows (to represent current operations of Friant Dam); and, (2) Demands in the American River Basin were reduced to an existing level, again to represent current conditions. Compared to the CWC-provided CalSim II 2030 and 2070 models, the current conditions (2017) CalSim II model reflects historical-based hydrology (i.e., no climate change); it removed operational rules added to the 2030 and 2070 CalSim models for operations under climate change; and reflects the SJRRP and American River Basin demand changes described above. As required in Section 6004(a)(1)(A), surface water and groundwater operations, resource conditions, and information to aid in quantifying benefits and costs of the Project are defined and included through use of the models described above. As required in Section 6004(a)(1)(B), all infrastructure, population, land use, water use, water operations, laws, regulations and other characteristics relevant to the analysis of the project, including all existing mitigation or compliance obligations? are included through use of the CalSim II, WEAP models described above.

be affected by the Project are included in the analysis. Per Section 6004(a)(1)(D), climate change and sea-level rise in 2030 and 2070 are represented in the models used (CalSim II, WEAP, and PCSHS), as described above.

Q.1:

Describe how the project improves the operation of the state water system. See regulations section 6003(a)(1)(M).

Pursuant to Section 6003(a)(1)(M) of the regulations, the Pacheco Reservoir Expansion Project would improve the operation of the state water system, including local, regional, state, and federal systems. The Project would expand south-of-Delta storage that is interconnected with both CVP and SWP. The Project would improve overall system reliability and delivery flexibility, particularly for

joint CVP/SWP San Luis Reservoir operations. During summer, high temperatures and low water levels create conditions that foster algae growth which is a problem for the San Felipe Division when San Luis Reservoir levels fall below 300 TAF and algae blooms reach the San Felipe Division intakes, the catalyst for the San Luis Low Point Improvement Project. Water quality within the algal blooms is unsuitable for M&I water users relying on existing SCVWD water treatment facilities. Further, the San Felipe Intake in San Luis Reservoir cannot operate when storage levels are below 326 feet (79 TAF), yet releases can be made to the Delta-Mendota Canal or California Aqueduct down to approximately 273 feet. - Improved Water Quality: Avoid the San Luis Reservoir low-point condition by delivering SCVWD supplies to the Project earlier in the season, providing additional local supplies from the Project, and using the Project as a source blending water. - Increased System Flexibility: Reduce operational challenges, and increase effective storage for other San Luis Reservoir users, through avoided conflict during low-point conditions and allowing the full reservoir capacity of San Luis Reservoir to be exercised. - Improved Transfer and Exchange Opportunities: Enable transfer of water from San Luis Reservoir to Pacheco Reservoir, allowing for improved management of non-project water in San Luis Reservoir, and reducing loss of investment in non-project water being spilled. Other federal, state, and regional benefits of the Project include: - Reduced Delta Pumping at Critical Biological Periods: During extreme drought conditions, CVP/SWP export facilities are operated for essential human health-and-safety water supplies. Allocation of these supplies to SCVWD are based on availability of local supplies. With the Project, SCVWD will have additional local supplies, potentially reducing Delta exports during drought periods. - Delta Watershed: Increasing IL4 supplies from SCVWD's water supplies may reduce transfer of north of Delta supplies and related Delta exports. - Delta-Export Interruption: In the event of a Delta-export failure, SCVWD would have additional local emergency response water supplies available. Supplies stored in San Luis Reservoir could be made available to other regional water users. - Drought Resilience: The Project will improve SCVWD water supplies during drought periods, allowing SCVWD to reduce reliance on the Semitropic Groundwater Banking Program. Thus, it may increase the operational flexibility of Semitropic storage for other water users during these periods. The Project would improve regional management of water resources along Pacheco Creek and the Pajaro River, including: - Reduced Flood Risk: The Project may reduce peak 100-year event flood flows from Pacheco Reservoir by 61 percent, reducing flows along Pacheco Creek and downstream areas. - Increased Groundwater Recharge: Flows from storm events would be stored for later release to Pacheco Creek at rates that improve groundwater conditions for downstream basins. - Improved Operational Flexibility: Groundwater supply increases along Pacheco Creek can improve flexibility and water quality for basin users. The Project would also provide significant local flexibility, including: - Local Operational Flexibility: Increase local surface storage capacity in Santa Clara County by 90 percent. - Contribution to SGMA: Protection of groundwater levels, resulting in decreased risk of permanent land subsidence. Improved flexibility and timing of groundwater recharge.

Q.2:

Describe how the project provides a net improvement in ecosystem and water quality conditions required by Water Code section 79750.

The Pacheco Reservoir Expansion Project will provide net improvements in the ecosystem and water quality conditions, as required by Water Code Section (Section) 79750. If constructed, the Project would provide net improvements for south-of-Delta wildlife refuges and Central Coast fishery habitats. In addition, the Project would yield improved water quality conditions in the event of a system failure in the Sacramento-San Joaquin Delta (Delta), and during low point events in San

Luis Reservoir. Project would also support actions of local Groundwater Sustainability Agencies that are formed in response to the Sustainable Groundwater Management Act of 2014 by improving downstream groundwater quality. The Project will transfer 2,000 acre-feet of SCVWD's water supply during below normal water years to the Incremental Level 4 refuge water supply, managed by the U.S. Department of the Interior, Bureau of Reclamation (Reclamation) and U.S. Fish and Wildlife Service, through the Refuge Water Supply Program, in accordance with Section 79753 (a)(1). This water supply would be available to state, federal, and private refuges in the San Joaquin River Hydrologic Region (DWR Bulletin 160-05). SCVWD has requested that Reclamation dedicate this supply to Grassland Resource Conservation District (GRCD), in accordance with Section 79752, which provides water to the largest contiguous block of wetlands remaining in California's Central Valley. The transfer could allow GRCD to irrigate 1,000 acres of wetlands toward optimization of wetland habitat for migratory birds on the Pacific Flyway and other terrestrial species. The proposed Project, consistent with Section 79753 (a)(1), supports establishment of a functionally independent South-Central California Coast (SCCC) steelhead population in the Pajaro River watershed through actions that improve water flow and temperature under all hydrologic conditions in Pacheco Creek, and provide flows that contribute to steelhead recovery in other downstream tributaries. The existing North Fork Dam cannot consistently support a steelhead fishery due to its size and the ephemeral condition of the Pacheco Creek system. Expanding Pacheco Reservoir would provide suitable flow and water temperatures (in accordance with Section 79753(a)(2)) to more than 10 miles of Pacheco Creek, including multiple consecutive dry ears. Habitat established through the Project could provide resiliency to at-risk runs in other Pajaro River tributaries, such as Uvas Creek. If constructed, the Project would provide a significant water quality improvement in drinking water conditions as a blending source for less desirable quality water and as an emergency water supply. This supply would be used during severe drought situations, in the event of system outages, and failure of one or more Delta levees. All of these situations have the potential to cause excess salinity, from the San Francisco Bay, to reach the export facilities at the Jones and Banks pumping plants. In addition, SCVWD would be able to switch to Pacheco Reservoir supplies if algae-bloom conditions occur in San Luis Reservoir. During low water level periods, the water quality within the algal blooms is particularly not suitable for agricultural or M&I water users. Water stored in SLR could be pumped and stored in the expanded Pacheco Reservoir earlier in the season, and released to SCVWD during low-point conditions. This solution would avoid the water quality impacts of algal growth in San Luis Reservoir. Finally, the Project may be able improve groundwater quality in the Pajaro Valley subbasin, which is managed by the Pajaro Valley Water Management Agency in accordance with Section 7975(1)(b). In the summer months, the Pajaro River runs dry, or experiences degraded water quality. Increased fresh flow releases from the Project into the Chittenden Gap can dilute nutrient-rich surface water in the Pajaro River and assist in improving groundwater quality downstream.

Q.3:

If applicable, summarize how the applicant is coordinating with the owners and operators of water system facilities not owned or operated by the applicant or project partners that may be affected by the project. See regulations section 6003(a)(1)(P).

Pursuant to section 6003(a)(1)(P) of the California Code of Regulations, SCVWD has implemented, and continues to conduct, multi-agency coordination efforts associated with the Pacheco Reservoir Expansion Project.This engagement has included owners and operators of Central Valley Project (CVP) and appurtenant facilities, and owners and operators of certain flood management facilities within the Pajaro River watershed. Coordination has included in-person and teleconference meetings, the exchange of technical documents, and execution of formal agreements, where

applicable. This coordination has focused on three distinct water-management actions: - Conveyance of SCVWD CVP supplies to the expanded reservoir - Conveyance of Incremental Level 4 (IL4) refuge water supplies to south-of-Delta refuges - Conveyance of water released from the expanded reservoir to U.S. Army Corps of Engineers' (USACE) flood management facilities A 150,000-gallon storage tank would be constructed near San Luis Reservoir (SLR) to regulate flows to the expanded reservoir. A 4,700-foot pipeline would connect the reservoir to the Pacheco Conduit (part of San Felipe Division of the CVP, a facility owned by the U.S. Department of the Interior, Bureau of Reclamation (Reclamation), and operated and maintained under contract to SCVWD. The San Felipe Division is the point of diversion for SCVWD, and partner agency San Benito County Water District, to receive their CVP allocations. To coordinate planning, design, and construction of the new pipeline and storage tank, SCVWD has held pre-planning meetings with Reclamation management, and intends to execute formal cost-sharing agreements following the identification of a federal lead, pursuant to the National Environmental Policy Act (NEPA). Improvements to the Sacramento-San Joaquin Delta (Delta) ecosystem achieved through the Project consist of SCVWD allocating 2,000 acre-feet of its water supply during below normal water years to the Refuge Water Supply Program (RWSP), for use in the IL4 water supply pool for wildlife refuges. Managed by Reclamation and U.S. Fish and Wildlife Service, the RWSP was created through passage of the Central Valley Project Improvement Act in 1992, to provide designated water to optimize wetland and wildlife habitat. The allocated water supplies would be realized through transfer of SCVWD?s CVP long-term water supply contract, or through transfer or exchanges with other water districts. SCVWD has held initial phone and in-person meetings with RWSP staff and Reclamation contract managers to explore contract actions for the RWSP transfer. This coordination contributes towards memorialization of the IL4 transfer, and documents Reclamation's distribution of IL4 water to Delta watershed refuges via agreements held by Reclamation with third-party agencies. While Reclamation sets priorities for IL4 distribution, SCVWD has expressed its desire that the transferred water be designated to refuges supported by Grassland Resource Conservation District. Water released to Pacheco Creek by the Project is conveyed to the Pacific Ocean via natural and constructed channels. The Pajaro River downstream of the Pacheco Creek, in the counties of Santa Cruz and Monterey, are flood management facilities constructed by USACE in partnership with local agency members of the Pajaro River Watershed Flood Prevention Authority (PRWFPA). Coordination with local agencies has included phone and in-person meetings with PRWFPA and the Santa Cruz County Flood Control and Water Conservation District, Zone 7. The SCVWD intends to execute formal agreements with affected local agencies during completion of feasibility studies. Coordination with USACE has included a pre-application meeting at their San Francisco District headquarters. This coordination will be documented with a work plan for compliance with Section 401 and 404 of the Clean Water Act, and execution of a funding agreement.

Q.4:

Describe how the project advances the long-term objectives of restoring the ecological health and improving water management for beneficial uses of the Delta. See regulations section 6003(a)(1)(R).

The Pacheco Reservoir Expansion Project (Project) expands water management system flexibility for long-term actions that improve the ecological health of the Sacramento-San Joaquin Delta (Delta), by transferring 2,000 acre-feet of Santa Clara Valley Water District's (SCVWD) water supply (during below normal water years) to the Refuge Water Supply Program?s (RWSP) Incremental Level 4 (IL4) refuge water supply pool. The RWSP is managed by the U.S. Department of the Interior, Bureau of Reclamation (Reclamation) and U.S. Fish and Wildlife Service (FWS), in

accordance with Section 79753 (a)(1). RWSP partner agencies include the California Department of Fish and Wildlife, Grassland Resource Conservation District (GRCD), and the Central Valley Joint Venture. Distribution of IL4 supplies are determined by RWSP and its partner agencies through a collaborative process that seeks to allocate limited available supplies to high priority refuges through an adaptive management process. SCVWD intends to participate in this collaborative process and work with the agencies to select a resource from the District?s water supply portfolio that best matches the IL4 refuge priorities when below normal water years are declared. Final selection of IL4-eligible refuges for allocated water is subject to Reclamation authority; however, SCVWD has requested its allocation be dedicate this supply to the GRCD, in accordance with Section 79752, which provides water to the largest contiguous block of wetlands remaining in California's Central Valley. The transfer could allow GRCD to irrigate 1,000 acres of wetlands (during below normal water years) for forage production of waterfowl on the Pacific Flyway. The wetlands are also home to shorebirds, giant garter snake, western pond turtle and other terrestrial species. Supporting documentation, on how providing additional water to the Incremental Level 4 Refuge Water Supply Pool advances the long-term objectives of restoring the ecological health of the Delta, can be found in the California State Wildlife Action Plan under Goal 1 Abundance and Richness, Goal 2 Enhance Ecosystem Conditions, and Goal 3 Enhance Ecosystem Function. If constructed, the Project would also improve water management for Delta beneficial uses, by improving local-area water supplies and providing for management flexibility. SCVWD is currently dependent on Delta exports for approximately 45 percent of its supplies (under 2030 future conditions). This water must be delivered year-round for municipal and industrial purposes. The expansion of Pacheco Reservoir would increase local water storage and would improve flexibility of water delivery management to the SCVWD system. SCVWD could take its supplies when ecological demands on Delta are low, giving flexibility to State and federal operators. Similar management strategies could also help Delta water management during dry years and emergencies, when health and safety deliveries become critical. SCVWD already operates a highly integrated system of reservoirs, infiltration basins, groundwater wells, and supply pipelines. Adding more storage improves SCVWD?s ability to forgo Delta exports for sensitive periods of time, and allows for local-supply augmentation during periods with very-low exports from the Delta. In periods when the Delta is experiencing high salinity (bromide), local supplies provide much-needed blending water to achieve water quality criteria for treated drinking water. Supporting documentation, on how increased local supply advances the long-term objectives of improving water management for beneficial uses of the Delta, can be found in the California State Wildlife Action Plan under Action 2 Increase Regional Self Reliance and Integrated Water Management, and Action 5 Manage and Prepare for Dry Periods.

Q.5:

Describe how the applicant will ensure that the proposed project will comply with and be consistent with all applicable local, state, and federal laws and regulations, including existing environmental mitigation or compliance obligation requirements. See regulations section 6003(a)(1)(V).

The Santa Clara Valley Water District (SCVWD) maintains ongoing engagement with local, state and federal regulatory agencies for development, issuance and conformance with required permits. These have included permitting for 10 reservoirs owned and operated by SCVWD, including seismic upgrades to Anderson and Coyote Dams. This experience demonstrates the proven track record SCVWD possesses to meet all applicable federal, state, and local laws and regulations for the Pacheco Reservoir Expansion Project (Project). These can range from compliance with state and federal acts?including the National Environmental Policy Act (NEPA), Endangered Species Act, Clean Water Act, Clean Air Act, National Historic Preservation Act, California Environmental

Quality Act (CEQA), California Endangered Species Act, and Porter-Cologne Water Quality Control Act, in compliance with the California State Water Code. The Project will also pursue compliance with local and regional plans and policies, including general plan requirements and land-use ordinances. SCVWD fully understands and appreciates the federal, state, and local requirements and applicable laws relevant to this Project. Coordination with federal, state, and local representatives responsible for implementing these laws and requirements is ongoing. A complete list of all current local, state, and federal permits and approvals required for the Project is included in this Water Storage Infrastructure Program application, under the Feasibility and Implementation Risk Attachment A2: Permit List. Regulatory agencies have been contacted early on, as described above, and will be involved throughout Project development. SCVWD has met with the U.S. Department of the Interior?s Bureau of Reclamation and U.S. Fish and Wildlife Service, the U.S. Army Corps of Engineers' San Francisco District (USACE), the National Marine Fisheries Service, and California Department of Fish and Wildlife (CDFW) regarding the Clean Water Act Section 404 permit. SCVWD has also engaged the State Water Resources Control Board on requirements for water rights. In addition, permits issued by USACE, CDFW, California Department of Water Resources Division of Safety of Dams, Santa Clara County, and others may establish additional compliance-obligation requirements that must be implemented. Meeting with key regulatory and agency staff throughout Project development will allow SCVWD to fully understand the compliance and permitting requirements, and to clearly establish expectations with each applicable agency. SCVWD has served as lead CEQA agency for multiple joint Environmental Impact Statement and Environmental Impact Reports that met all NEPA/CEQA requirements, including environmental mitigation, and fully recognizes the importance of complete and defensible compliance documents. For permitting compliance, SCVWD understands that the permit applications must be completed in a timely manner, and must address all the subtleties and nuances of the permitting process. SCVWD will ensure compliance with permits by thoroughly understanding the environmental mitigation and compliance obligation requirements for the Project, and by integrating the compliance obligations into the design process. One way to ensure this is to overlay the design drawings with the mitigation and obligation requirements. This approach puts both design information, and all associated mitigation and obligation requirements, in one location. The Project, if advanced to construction, will be integrated to existing permit mitigation and compliance monitoring protocols performed by SCVWD. The SCVWD anticipates preparation of a permit-compliance log as part of overall project reporting to the Commission consistent with the Water Storage Investment Program application.

Section : EARLY FUNDING REQUEST

EARLYFUNDINGREQUEST

Q.1:

Is early funding for completing environmental documentation and/or permits requested? If yes, answer the following question and provide the requested information. See regulations section 6003(a)(1)(X).

An expanded Pacheco Reservoir (proximate to the pipeline that conveys Central Valley Project water from San Luis reservoir to Santa Clara and San Benito counties) could potentially improve Santa Clara Valley Water District?s (SCVWD) water supply reliability by increasing operational flexibility and augmenting dry and critical year supplies. The project could also provide emergency supply, improve drinking water quality, enhance the run of South Central Coast steelhead on Pacheco Creek and provide some downstream flood reduction benefits. The capital cost for expanding the reservoir from about 6,000 acre-feet to 141,800 acre-feet is estimated at $969 million, based on 2015 price levels in accordance with the WSIP Technical Reference. Project is seeking 50 percent of the capital costs from WSIP, equal to $484.5 million. The present value of net Project public benefits is $1,177 million. On the basis of the requested WSIP funding, the public benefit ratio for the Project is 2.43. Therefore, the Project is a cost-effective project to achieve the intended public benefits. The present value of the total Project cost is $1,181 million, while the present value of the net Project benefits is $1,459 million. The ratio of present-value of total-monetized net benefits to present-value of total-Project costs is 1.23. Therefore, the Project is cost effective because the benefits exceed the cost. The planning, design, and permitting stages of the Pacheco Reservoir Expansion Project (Project) must be initiated simultaneously, and significant work must be completed to meet the statutory deadline to complete draft California Environmental Quality (CEQA)/National Environmental Policy Act (NEPA) documents by January 2022. Multiple phases of field investigations may be necessary to finalize the location of the dam and initiate the feasibility-level design to complete the draft CEQA/NEPA documents. Biological surveys spanning multiple years, as well as cultural surveys, would have to be completed to initiate the lengthy Section 401.404 permitting process with the Regional Water Control Board and the U.S. Army Corps of Engineers. Supported by the information in the Application, SCVWD concludes that the Project is viable not only for public benefits it provides, but for costs associated with non-public benefits that SCVWD would be responsible for. The environmental documentation and permitting process must be initiated expeditiously so that the January 2022 deadline for a draft CEQA document deadline can be met. The District plans to initiate in September 2017 the procurement process to hire consultants to proceed with CEQA-level preliminary design, permitting and environmental documentation. The District?s Board will be requested by September 2017 to authorize funding for 2017-2018 efforts, and subsequent annual budgets will also be submitted for Board approval. SCVWD requests early funding assistance from WSIP consistent with the primary importance of the environmental purposes of the Project.

Q.2:

What is the requested amount?

SCVWD estimates that the cost to complete the environmental documentation and permitting for the Pacheco Reservoir Expansion Project (Project), including design would cost approximately $86.2 million, as provided in the Scope of Services, schedule and budget provided in Tab A1. As per section 6010(b)(4) of regulation, SCVWD is requesting $24.2 million from WSIP, which is 5 percent of the maximum eligible funding request of $484.5 million. SCVWD will provide remaining funds to complete the committed work. District has the financial capability to complete the environment documentation and permitting of the Project. District is currently working on several high priority capital projects. In the absence of early funding, some of these projects may be delayed, or eliminated, to provide the necessary funding for the Project. Board is willing to commit the necessary funds to move the project forward. SCVWD is serving as the applicant for WSIP funding for the Project. Several partners have been engaged in the development of the Project and this WSIP application. However, SCVWD is not dependent on other Project partners to help fund and implement the Project. SCVWD has both the financial capacity and organizational experience to successfully implement the Project. SCVWD is financially strong today as evidenced by credit ratings that are among the highest for a water-related governmental entity in the state of California (currently Aa1 from Moody?s, AA+ from Fitch, and AA- from S&P). SCVWD?s strong financial capability is due to sound financial management, and the Board?s willingness to raise water rates sufficiently to maintain financial strength. SCVWD will have the capacity to fully finance its share of both capital and O&M costs without cost share from other Project partners, assuming continued Board willingness to sufficiently raise water rates. SCVWD, through legacy organizations, has been planning, designing and constructing water resources projects since 1929, including 10 dams and reservoirs. SCVWD has significant recent experience in implementing large capital programs for ecosystem improvement, water supply, and flood risk reduction. SCVWD?s ability to independently fund and implement the Project reduces the implementation risk to the CWC and would help ensure likelihood of Project implementation and recognition of identified public benefits.

A.1 Early Funding Scope, Schedule, Budget:

Attach a schedule, scope of work, and budget.

•Keep in mind that the applicant must provide a 50 percent cost share and reimbursable costs can only go back to November 4, 2014.

•Scope of work must include an explanation of why early funding is critical to the project, the viability of the project in the absence of this funding and how the project will proceed once early funding is expended.

•The scope of work cannot include work performed prior to submittal of the application.

•The tasks in the schedule, scope of work and budget should match.
