2 7. Type of Proposal: Is your project an implementation project (developed, with budget) or a concept proposal? Implementation project Concept proposal 8. Project Summary: Briefly describe your project (one paragraph): The new Castroville Water Supply Line Tank and System Improvements Project will provide a connection from the new Cal-Am desalination facility to the Castroville Community Services District s (District) potable water distribution system to off-set the demand on the deteriorating groundwater supply on which it currently relies upon 100%. This new, high quality, reliable supply will be used to off-set the water currently supplied by the District s groundwater wells which are of relatively poor quality. Levels of chlorides steadily increased due to seawater intrusion in Well No.3, to the point that as of April 2018 it does not meet SWRCB-DDW drinking water standards and can no longer be used, representing a 28% loss to the District s well production. Groundwater maps published by the Monterey County Water Resources Agency indicate the plume of sea water intrusion is moving closer the Castroville Well Systems, which may soon deteriorate quality of Well Nos. 2 and 4 in addition to the already deteriorated Well 3. Well No. 5 is discharged at elevated temperatures, and requires extensive and costly treatment to maintain levels of arsenic below the State of California Maximum Contaminant Level (MCL), and has aesthetic issues. Well No. 2 has insufficient capacity to serve a significant fraction of the District s demands. The proposed Cal-Am connection will convey water from the new Cal-Am desalination facility in Marina to the District s potable water distribution system in Castroville via a 12-inch diameter cement mortar lined ductile iron pipe, approximately 2 miles in length. The pipeline will tie in to the existing District potable water distribution system at the District s Well No. 3. Water from the Cal-Am connection will be either discharged directly into the potable water distribution system or stored in tanks for use during peak demand periods. Water will be provided at a flow rate between 500 and 1,000 gallons per minute (gpm) with a total annual supply of 680 acre-feet per year (AFY). The District has two potable water storage tanks, one at the Well No. 2 site with a storage volume of 500,000 gallons, and one at the Well No. 4 site with a volume of 630,000 gallons, for a combined total storage volume of 1,130,000 gallons. Water purchased from Cal-Am not utilized directly in the distribution system will be stored in these tanks for use during peak demand periods. The District will construct an additional potable water storage tank at the Well No. 4 site to provide additional storage and operational redundancy. This desire is supported by the North County Fire Protection District of Monterey County, as documented in a letter, dated September 21, 2017, affirming this additional storage capacity will increase water available for fire protection. Additionally, increased storage will allow existing storage facilities to be removed from service for rehabilitation while still being able to meet maximum daily demands. Additional storage will also reduce risks associated with a shutdown of the Cal-Am water production facility, power outage, conveyance pipeline rupture, or other issues. The District will maintain operation of existing groundwater pumping facilities for emergency conditions and to provide approximately 100 AFY of potable water production. COST SUMMARY: Requested Funds: $3,501,000 Match: $2,800,000 TOTAL: $6,301,000 2

4 11. IRWM Plan Objectives The following objectives have been identified for the Greater Monterey County IRWM Plan. Please select all of the objectives that the project will address, and very briefly explain (unless it is entirely obvious) how your project will address each objective. (For concept proposals, you need not provide the justification.) Objective Water Supply Goal Increase groundwater recharge and protect groundwater recharge areas. Optimize the use of groundwater storage with infrastructure enhancements and improved operational techniques. Increase and optimize water storage and conveyance capacity through construction, repair, replacement, and augmentation of infrastructure. Diversify water supply sources, including but not limited to the use of recycled water. Maximize water conservation programs. Capture and manage storm water runoff. Optimize conjunctive use where appropriate. Support research and monitoring to better understand water supply needs. Support the creation of water supply certainties for local production of agricultural products. Justification Developing a new supply will off-set groundwater pumping and allow in-lieu recharge of the groundwater basin, allowing groundwater levels to rise and offering protection from continued seawater intrusion. District currently uses approximately 800 AFY. Cal-Am project will deliver approximately 700 AFY, reducing the District s pumping to 100 AFY. Improved groundwater pumping operations allow groundwater levels to rise and protect the basin from further seawater intrusion. Cal-Am s proposed Desalination Facility will be sized to offer Castroville their needed supply; Castroville will construct the conveyance and storage needed to optimize the use of the Cal- Am supply. Castroville drinking water currently relies 100% on groundwater; the Cal-Am desal supply will diversify the Castroville water supply source. CCSD has low flow toilet rebates and enforces regulations for water waste and participates in the Water Awareness Committee that dispenses information and tips on how to conserve water [HOWEVER, THIS IS NOT PART OF THE PROJECT] The Cal-Am supply will allow the District s groundwater pumping to be reduced to 100 AFY for emergency conditions and some potable water production; the new tank will also reduce risks associate with a shutdown of the Cal-Am water production facility, power outage, conveyance pipeline rupture, or other issues. The new Cal-Am supply will offset the District s groundwater pumping. The District s and MCWRA s groundwater monitoring of the groundwater elevations and seawater intrusion fronts after the project is on-line will improve the region s understanding of how the basin reacts and how quickly it can recover from modified groundwater extraction conditions, informing the sustainable use of groundwater supplies in the future. [EH NOT REALLY PART OF THE PROJECT] While the project involves the development of a new potable supply, it offsets the demand on 4

Water Quality Goal Promote practices necessary to meet, or where practicable, exceed all applicable water quality regulatory standards (for drinking water, surface and groundwater quality). the critically overdrafted groundwater basin, providing better groundwater conditions for agricultural water pumpers. CCSD is a member of the Water Awareness Committee of Monterey County and participates in water education and conservation. [NOT PART OF THE PROJECT] As of April 2018, Well No.3 no longer meets SWRCB-DDW drinking water standards due to Seawater Intrusion and can no longer be used, representing a 28% loss to the District s well production. The remaining District wells are threatened by SWI. The Cal-Am supply will provide the drinking water necessary to supply the community while off-setting the demand on the groundwater basin, protecting it from further seawater intrusion. As of April 2018, Well No.3 no longer meets SWRCB-DDW drinking water standards due to Seawater Intrusion and can no longer be used, representing a 28% loss to the District s well production. Groundwater maps published by MCWRA indicate the plume of seawater intrusion is moving closer the Castroville Well Systems, which may soon deteriorate quality of Well Nos. 2 and 4. Well No. 5 is discharged at elevated temperatures, and requires extensive and costly treatment to maintain levels of arsenic below the MCL, and has aesthetic issues. Well No. 2 has insufficient capacity to serve a significant fraction of the District s demands. The Cal-Am supply will provide potable water that meets or exceeds drinking water standards. Promote projects to prevent seawater intrusion. Castroville currently uses approximately 800 AFY. Cal-Am project will deliver approximately 700 AFY, reducing the District s pumping to 100 AFY and off-setting the demand on the groundwater basin. Reduced groundwater pumping operations allow groundwater levels to rise and protect the basin from further seawater intrusion. Incorporate or promote principles of low impact development where feasible, appropriate, and cost effective. Protect surface waters and groundwater basins from As of April 2018, Well No.3 no longer meets contamination and the threat of contamination.

Reducing the District s pumping from 800 AFY to 100 AFY and off-setting the demand on the groundwater basin allow groundwater levels to rise and protect the basin from the threat of seawater contamination. The new Cal-Am supply will offset the District s groundwater pumping. The District s and MCWRA s groundwater quality, groundwater elevation, and seawater intrusion (salinity) front monitoring after the project is on-line will improve the region s understanding of how the basin reacts and how quickly it can recover from modified groundwater extraction conditions. The new Cal-Am supply will offset the District s groundwater pumping.

Disadvantaged Communities Goal Seek funding opportunities to ensure all communities have a water system with adequate, safe, high-quality drinking water. years to ensure the new desalination project accounts for and is designed to supply the potable water demands of the District s service area in addition to the Cal-Am service area. Castroville has participated in federal and state regulator meetings and hearings expressing the critical need for the Cal-Am desalination project to supply Castroville and compliance with drinking water quality requirements. Castroville has been working with Cal-Am over many years to ensure the new desalination project accounts for and is designed to supply the potable water demands of the District s service area. Castroville currently uses approximately 800 AFY. Cal-Am project will deliver approximately 700 AFY, reducing the District s pumping to 100 AFY and off-setting the demand on the groundwater basin. Reduced groundwater pumping operations allow groundwater levels to rise and protect the basin from further seawater intrusion. While the project involves the development of a new potable supply, it offsets the demand on the critically overdrafted groundwater basin, providing better groundwater conditions for agricultural water pumpers and mitigating potential conflicts between groundwater users in the region. While the Cal-Am project is being implemented, Castroville continues to work on the potential development of a replacement well that is located in an area safe from seawater intrusion. The District will maintain operation of existing groundwater pumping facilities for emergency conditions and to provide approximately 100 AFY of potable water production. Castroville will continue to work with federal, state, and local agencies to ensure the Castroville wells are adequately sited and sized to ensure consistency with the Cal-Am project and meets the requirements of the regulatory agencies. CCSD is a member of the Water Awareness Committee of Monterey County and participates in water education and conservation as well as meeting with the County Supervisors and Staff Based on a request from the SWRCB, the Rural Community Assistance Corporation (RCAC) performed an income survey of the Castroville service area to establish a median household income (MHI) level for state and federal funding. The income survey was conducted per Multi-Agency Guidelines for MHI Survey established for the SWRCB Clean 8

Water/Drinking Water SRF programs and the USDA Rural Development program. As documented in the survey results letter dated March 30, 2017, the District, with an MHI of $35,000, qualifies as a Severely Disadvantaged Community. The new Castroville Water Supply Line Tank and System Improvements Project will provide a connection from the new Cal-Am desalination facility to the Castroville Community Services District s (District) potable water distribution system to off-set the demand on the deteriorating groundwater supply on which it currently relies upon 100%. This new, high quality, reliable supply will be used to offset the water currently supplied by the District s groundwater wells which are of relatively poor quality and ensure that the Castroville community has an adequate, safe, high-quality drinking water.

[NOT REALLY] Castroville currently uses approximately 800 AFY. Cal-Am project will deliver approximately 700 AFY, reducing the District s pumping to 100 AFY and off-setting the demand on the groundwater basin. Reduced groundwater pumping operations allow groundwater levels to rise and protect the basin from further seawater intrusion now and under a changed climate. [NO] The District s drinking water wells are experiencing increasing chloride levels due to seawater intrusion and these conditions are expected to worsen given the effects of sea level rise, potentially impacting all of the Castroville drinking water wells. The only truly suitable adaptation measure is to reduce or stop pumping from those groundwater wells, allow groundwater elevations to recover, and stop further seawater intrusion. To accommodate this adaptation measure, an alternative surface supply like the Cal-Am desal water is required. CCSD collaborates with Monterey County Water Regarding Agency regarding public education programs and water resource management. [HOWEVER, NOT PART OF THIS PROJECT] 10

11 SECTION II. RESOURCE MANAGEMENT STRATEGIES AND CLIMATE CHANGE This section is required for all implementation projects. If your project is a concept proposal, there is no need to complete this section (or any of the following sections of this application form). 12. Do you want your project to be considered for Round 1 of the Proposition 1 IRWM Implementation Grant Program? Yes No 13. Resource Management Strategies One of the goals of integrated regional water management planning is to encourage diversification of water management approaches. Please select the strategies that your project will use (check all that apply): Reduce Water Demand Agricultural Water Use Efficiency Urban Water Use Efficiency [NO] Improve Operational Efficiency and Transfers Conveyance System Reoperation Water Transfers Infrastructure Reliability Increase Water Supply Conjunctive Management & Groundwater Storage Desalination Precipitation Enhancement Recycled Municipal Water Surface Storage Storm Water Capture and Management Improve Water Quality Drinking Water Treatment and Distribution Groundwater/Aquifer Remediation Matching Water Quality to Use Pollution Prevention Salt and Salinity Management Urban Runoff Management Water and Wastewater Treatment Practice Resources Stewardship Agricultural Lands Stewardship Ecosystem Restoration Forest Management Land Use Planning and Management Recharge Area Protection Sediment Management Watershed Management [NO] Environmental and Habitat Protection and Improvement Wetlands Enhancement and Creation Improve Flood Management Flood Management People and Water Economic Incentives (Loans, Grants, and Water Pricing) [NO] Outreach, Engagement, and Education Water and Culture Water-Dependent Recreation Regional Cooperation Recreation and Public Access Other Resource Management Strategies Dewvaporation or Atmospheric Pressure Desalination Fog Collection Rainfed Agriculture Monitoring and Research 11

12 14. Climate Change Adaptation a) Does your project contribute to climate change adaptation? If so, what climate change vulnerabilities in the region does your project respond to, specifically? (For vulnerabilities in the Greater Monterey County IRWM region, see Chapter R Climate Change of the IRWM Plan, specifically Section R6, available at: Please describe how, and to what extent. Yes, the Castroville Water Supply project contributes to the adaptation to reduced rainfall, sea level rise, and their impacts to the volume and quality of the groundwater supplies and the risk of coastal storm flooding of the drinking water wells. With reduced rainfall, there will be less recharge to the already overdrafted groundwater basin, making it even more vulnerable to sea level rise and seawater intrusion. Additionally, Castroville groundwater wells are located within future coastal storm flooding hazard zones. If these wells are flooded with surface salt water, it is assumed that many of the wells may allow saltwater intrusion to one or multiple aquifers. The Castroville project will allow a new reliable supply, not affected by climate change, to off-set groundwater pumping and allow in-lieu recharge of the groundwater basin, allowing groundwater levels to rise and offering protection from continued seawater intrusion. b) Does your project consider the effects of sea level rise on water supply conditions and identify suitable adaptation measures? Yes, the District s drinking water wells are experiencing increasing chloride levels due to seawater intrusion and these conditions are expected to worsen given the effects of sea level rise, potentially impacting all of the Castroville drinking water wells. The only truly suitable adaptation measure is to reduce or stop pumping from those groundwater wells, allow groundwater elevations to recover, and stop further seawater intrusion. To accommodate this adaptation measure, an alternative and reliable surface supply not affected by climate change is required, like the Cal-Am desal water supply. c) Does the project take into consideration changes in the amount, intensity, timing, quality and variability of runoff and recharge? Yes, the District s planning takes into consideration the anticipated reductions of precipitation and groundwater recharge, leading to a need to reduce its reliance on groundwater and identify an alternative and reliable surface supply not affected by climate change, like the Cal-Am desal water supply. 15. Reduction of Greenhouse Gas Emissions This analysis has not yet been completed a) Please describe the extent to which your project will help reduce greenhouse gas (GHG) emissions, compared to project alternatives. To assist you in estimating GHG emissions, please use the California Emissions Estimator Tool (CalEEMod) available for download at Guidance documents to help you use the tool are available on the Greater Monterey County IRWM website at: b) If appropriate, describe the extent to which the project will help the region reduce GHG emissions over the next 20 years. c) To what extent will the project help reduce energy consumption, especially the energy embedded in water use, and ultimately reduce GHG emissions? 12

13 SECTION III. PROJECT NARRATIVE AND BUDGET Complete this and the following sections only if you would like your project to be considered for Round 1 Implementation Grant funds. 16. Project Description (1 page or so): Please describe the proposed project. Provide a general discussion of the problem the project addresses, and describe major tasks/activities. Include any other information that supports the justification for this project, including how the project can achieve any claimed benefits. The District serves more than 7,250 customers through 2,284 water connections in the community of Castroville. The District provides approximately 800 acre-feet of water annually to government, industrial, commercial, and residential customers. The District operates four domestic water production wells; the estimated capacity of all four wells is approximately 4.4 million gallons per day (mgd). The water currently supplied by the District s wells is of relatively poor quality. Levels of chlorides steadily increased in Well No.3, when in April 2018 it exceeded SWRCB-DDW drinking water standards and could no longer be used, representing a 28% loss to the District s well. Groundwater maps published by the Monterey County Water Resources Agency indicate the plume of sea water intrusion is moving closer the Castroville Well Systems, which may soon deteriorate quality of Well Nos. 2 and 4. Well No. 5 is discharged at elevated temperatures, and requires extensive and costly treatment to maintain levels of arsenic below the State of California Maximum Contaminant Level (MCL), and has aesthetic issues. Well No. 2 has insufficient capacity to serve a significant fraction of the District s demands. The proposed Cal-Am connection will convey water from the new Cal-Am desalination facility to the District s potable water distribution system via a 12-inch diameter cement mortar lined ductile iron pipe. Cal-Am will discharge water at a pressure of 180 pounds per square inch (psi); a pressure reducing valve will reduce the pressure as needed to achieve the desired system pressure in the District s system; a pressure of approximately 60 psi at the connection point is planned. Water will be provided at a flow rate between 500 and 1,000 gallons per minute (gpm) with a total annual supply of 680 acre-feet per year (AFY). The District will maintain operation of existing groundwater pumping facilities for emergency conditions and to provide approximately 100 AFY of potable water production. A new pipeline, approximately 2 miles in lengths, will convey water from the Cal-Am desalination facility in Marina to Castroville. The pipeline will tie in to the existing District potable water distribution system at the District s Well No. 3 site, near the intersection of Del Monte Avenue and Merritt Street (Highway 183). Water from the Cal-Am connection will be discharged directly into the potable water distribution system, with some limited controls. A check valve and automatic isolation valve will be provided, as well as sample taps for continuous ph and total dissolved solids (TDS) monitoring; a flow meter may also be provided at the Well No. 3 site. The District has two potable water storage tanks, one at the Well No. 2 site with a storage volume of 500,000 gallons, and one at the Well No. 4 site with a volume of 630,000 gallons, for a combined total storage volume of 1,130,000 gallons. Water purchased from Cal-Am not utilized directly in the distribution system will be stored in these tanks for use during peak demand periods. The District desires to construct an additional potable water storage tank at the Well No. 4 site to provide additional storage and operational redundancy. This additional storage capacity will also increase water available for fire protection and is supported by the North County Fire Protection District of Monterey County, as documented in a letter dated September 21, Additionally, increased storage will allow existing storage 13

14 facilities to be removed from service for rehabilitation while still being able to meet maximum daily demands. Additional storage will also reduce risks associated with a shutdown of the Cal-Am water production facility, power outage, conveyance pipeline rupture, or other issues. In addition to the new storage tank, process modifications including valves and piping are required to allow storage of water received from the Cal-Am connection at the well No. 4 site. Civil site improvements are also required at this site to provide a suitable site for the new storage tank, incorporate the new storage facility into the system and modernize and secure the facility. The District s potable water system encompasses approximately 13 miles of pipeline ranging in diameter from 4- inch to 14-inch within a single pressure zone. Pressure is currently maintained in the system by booster pumps located at the three well sites. The District does not have a hydraulic model of the system and as a result cannot accurately predict the impacts of shifting the source of supply from groundwater to the Cal-Am connection. A hydraulic model will be developed to verify system functionality with the new water supply. The tasks are summarized in the table below. Project Task Develop Calibrated Hydraulic Model and Prepare Report Conduct Storage Evaluation (New Tank Construction and Rehabilitation of Existing) Conduct Water Quality Evaluation Preliminary Design Develop Detailed Design Project Permitting Construction Improvements and Begin Operation Task Detail A Calibrated hydraulic model will provide a basis for all other planning activities. Development of the model will include a documentation report for model assumptions and modeling results. The Report will identify: Required Cal-Am water supply connection pressure Undersized water mains impacting available fire flows and conveyance capacities Approximate system set points for operation in a variety of operational scenarios Provide a basis for emergency response planning and future development Utilizing the calibrated hydraulic model, current condition assessments, and long term storage requirements for operation and maintenance, develop recommendations for improving water storage in the system Conduct an evaluation of the District s current water quality with anticipated Cal-Am water quality to identify risks, including chemical interactions and corrosivity concerns Develop preliminary design including design criteria. Complete necessary site investigations including topographic and boundary surveys and geotechnical investigations Develop complete contract documents for the intertie at the Well No. 3 site as well as any modifications to the distribution system, control systems, and water storage facilities required for the intertie Obtain necessary permits, and other administrative work required for improvement implementation including CEQA compliance, Coastal Development Permit, and other permits required for construction Construct the designed facility improvements and begin receiving water from Cal-Am. 17. Project Need/Urgent Need: Is there a special, urgent, or critical need for your project? If so, explain. Chloride levels in the Castroville drinking water wells have been steadily increasing. This was most recently demonstrated in Well No.3, when in April 2018 the well no longer met SWRCB-DDW drinking water standards and could no longer be used, representing a 28% loss to the District s well production. Groundwater maps published by MCWRA indicate the plume of sea water intrusion is moving closer the Castroville Well Systems, which may soon deteriorate quality of Well Nos. 2 and 4 in addition to the already deteriorated Well 3. Well No. 5 is discharged at elevated temperatures, and requires extensive and costly treatment to maintain levels of arsenic below the State of California Maximum Contaminant Level (MCL), and has aesthetic issues. Well No. 2 14

15 has insufficient capacity to serve a significant fraction of the District s demands. The new Castroville Water Supply Line Tank and System Improvements Project will provide a connection from the new Cal-Am desalination facility to the Castroville Community Services District s (District) potable water distribution system to off-set the demand on the deteriorating groundwater supply on which it currently relies upon 100%. 18. Budget: Please complete the following budget table. While only a high level budget is required at this time, please provide as much detail as possible. (The Regional Water Management Group is mainly interested in knowing that your budget is realistic and is based on actual costs.) The District has entered into a cost sharing and water purchase agreement with Cal-Am to fund a portion of the construction of the water supply system. The District s has agreed to reimburse Cal-Am a share of the conveyance pipeline construction in the amount of $2,800,000. The detailed cost estimate table includes the planning and design costs for all other project elements and the construction cost estimate includes all elements (including the District share of the conveyance pipeline).

16 19. Cost Share: DWR requires that proposals provide at minimum 50% non-state cost share. DWR awards additional points for proposals that provide more than the required 50% non-state cost share. Describe your cost share, and sources of cost share funds. Castroville is a Severely Disadvantaged Community and eligible for a waiver of the 50% match requirement. However, recognizing the limited funds available to the Greater Monterey IRWM region, Castroville is limiting the funding request to the project costs less the District s share of the pipeline connecting to the Cal-Am supply. Castroville will continue to pursue other funding for the pipeline costs. 20. Disadvantaged Communities: Does the project provide direct water-related benefits to a project area entirely comprised of Disadvantaged Communities (DACs) and/or Economically Distressed Areas (EDAs)? If so, explain. (If you need help with this question, contact Susan at srobinsongs@frontier.com) Yes, the project provides direct water-related benefits to the Severely Disadvantaged Community of Castroville. Based on a request from the SWRCB, the Rural Community Assistance Corporation (RCAC) performed an income survey of the Castroville service area to establish a median household income (MHI) level for state and federal funding. The income survey was conducted per Multi-Agency Guidelines for MHI Survey established for the SWRCB Clean Water/Drinking Water SRF programs and the USDA Rural Development program. As documented in the survey results letter dated March 30, 2017, the District, with an MHI of $35,000, qualifies as a Severely Disadvantaged Community. The new Castroville Water Supply Line Tank and System Improvements Project will provide a connection from the new Cal-Am desalination facility to the Castroville Community Services District s (District) potable water distribution system to off-set the demand on the deteriorating groundwater supply on which it currently relies upon 100%. This new, high quality, reliable supply will be used to off-set the water currently supplied by the District s groundwater wells which are of relatively poor quality and ensure that the Castroville community has an adequate, safe, high-quality drinking water. Will you be requesting a full or partial cost-share waiver based on DAC/EDA status? While eligible for a full waiver of the cost-share requirements based on the SDAC status, Castroville recognizes the limited funds available to the Greater Monterey IRWM region. Thus, Castroville is limiting the funding request to the project costs less the District s share of the pipeline connecting to the Cal-Am supply. Castroville is requesting $2.721 million in IRWM grant funds and will continue to pursue other funding for the $2.8 million pipeline costs. 21. Operations and Maintenance: Please describe how operations and maintenance of the project will be supported. O&M costs will be financially supported by water rates. 22. Storm Water Resource Plan Requirements: Is the project a storm water or dry weather runoff capture project? If so, is it included in a Storm Water Resource Plan? Not applicable. 23. Groundwater: Will the project affect groundwater levels? (yes or no) Yes indirectly. A new surface supply will offset current groundwater pumping. 24. AB 1249 Requirements: Does the project address nitrate, arsenic, or hexavalent chromium contamination in the region? If so, how? Not applicable. 25. Stakeholder Coordination: Please briefly describe the nature of stakeholder coordination for planning, developing, and implementing the project. CCSD is a member of the Water Awareness Committee of Monterey County and participates in water education and conservation as well as meeting with the County Supervisors and Staff. There has been 16

17 significant public outreach associated with the larger Cal-Am Desalination Project that will supply the Castroville service area through the proposed conveyance pipeline and storage tank. Castroville will initiate focused public outreach after funding is secured the environmental documentation process begins. SECTION IV.
