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 Salinas Area Flood Enhancements and Reuse Project (SAFER) is a series of improvements to the City of Salinas existing Industrial Wastewater Treatment Facility (IWTF) and storm water infrastructure with the ultimate goal of increasing the functionality of these facilities for multiple water resource and environmental benefits. The Blanco Retention Basin (Basin), located adjacent to Monterey One Water s (M1W) Salinas Pump Station (SAPS), requires upgrades to its subsurface french drains, pump, and piping to increase flood protection of nearby farmland by enabling the City to control the Basin with greater reliability and for improved water quality and water reuse yields (see Figure 1. Concept Site Plan- Blanco Retention Basin). SAFER also includes flood-proofing measures to the IWTF electrical cabinet and pump station (see Figure 2. Concept Site Plan- IWTF Influent PS and Electrical Cabinet). Currently, the electrical cabinet and influent pump station are located within the 100-year floodplain, making them vulnerable to inundation during large storm events. Additionally, if the IWTF influent pump station capacity is enhanced, the facility can better accommodate the full flows of storm water available for capture and beneficial reuse by Monterey One Water in its recycling operations at the Treatment Plant. M1W and the City are implementing the Salinas Storm Water (SSW) Projects under a SWRCB Prop 1 Storm Water Grant that will augment and repurpose the IWTF as a storm water and urban runoff seasonal storage site. The Project will enable winter storm water flows to become inflow to the Treatment Plant for beneficial reuse during summer months when demand exceeds water availability. The additional facilities proposed by the Project will further amplify the potential benefits of the SAFER Project beyond the City limits to a regional scale. In 2015, the City completed construction of a new, 42-inch industrial wastewater (IWW) pipeline to replace the original, 7,746 linear foot, 33-inch diameter gravity main between the City s TP1 site (the site on which M1W s SAPS is located) and the IWTF. Current design for the Salinas Stormwater (SSW) Phase 1B (Storage and Recovery) Project dictates that storm water from the southwestern portion of the City and IWW flows from the agricultural processors discharging to the City s industrial wastewater collection system will be comingled and conveyed to the IWTF through this recently-constructed 42-inch pipeline. The influent pump station will lift comingled flows to the aeration pond where it will undergo aeration treatment. The pumping and aeration of IWW is mandatory as prescribed by the facility s Waste Discharge Requirements (WDR) permit. Storm water alone does not require aeration due to low biological oxygen demand (BOD); however, due to comingling of storm water and IWW at TP1, this additional energy usage will be required. As a final component of the SAFER Project, the City and M1W propose to conduct a condition assessment and subsequent rehabilitation of the 33-inch pipeline to allow more diverse functionality by enabling capture and storage of additional storm water for reuse and optimized treatment of IWW (See Figure 3. SAFER Project Location Map). 1 During preliminary design of the SSW Projects, the 33-inch pipeline (abandoned-in-place) was identified as an opportunity to utilize existing infrastructure to provide operational flexibility of the IWTF, as well as to achieve energy savings by allowing conveyance of storm water to Pond 1 separate from IWW. Allowing storm water to bypass unnecessary pumping and aeration, would result in an estimated 10% reduction in the overall energy consumption of the IWTF. An additional benefit to separate conveyance of storm water and IWW is that the limiting factor for storm water yield possible for capture would not be the remaining capacity in the 1 This component of the project is included in the Salinas Water Quality and Agricultural Efficiency project also; should both projects be selected for funding, only one will include this component. 2

3 42-inch industrial pipeline. Instead, the amount of storm water able to be captured would be the full flowrate available in the 33-inch pipeline. This is anticipated to allow for a doubling of the amount of storm water captured and stored for recycling during summer months, resulting in the following benefits: A reduction of up to acre-feet/year (AFY) of storm water discharges to the Salinas River; An improvement in downstream flooding conditions; Additional total maximum daily load (TMDL) compliance for the City and associated water quality improvements in the River; and, Water supply benefits of increased use of the IWTF storage.

6 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. Justification Ensuring flood-resilient operations at the IWTF will allow for continuous, uninterrupted conveyance of industrial wastewater (IWW) and storm water (SW) to the TP for beneficial reuse through: 1. Salinas Valley Reclamation and Castroville Seawater Intrusion Projects: tertiary treatment facilities for agricultural reuse in the northern Salinas Valley to reduce grower reliance aquifer pumping from the critically overdrafted Salinas Valley Groundwater Basin; 2. Pure Water Monterey: indirect potable reuse project for groundwater replenishment of the Seaside Groundwater Basin and indirect potable reuse on the Monterey Peninsula to reduce diversion from the Carmel River for enhancement of habitat for Central California Coast (CCC) - Steelhead Salmon, California Red Legged Frog (CRLF), and other species 3. Some additional percolation to the Salinas Valley Groundwater Basin shallow aquifers is also anticipated which may assist in protecting the groundwater basin. 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. Uninterrupted IWW and SW conveyance is critical maximizing the water quality benefits and water supply yield of storm water captured and seasonally stored at the IWTF for diversion to the TP during summer months when water demand exceeds availability. The additional AFY of storm water captured by rehabilitation of the 33-inch line will support water recycling projects above, including the development of a drought reserve in the Seaside Basin of up to 1,000 AF for future water supply shortages. Please see above. All-weather-capable operations are critical to optimizing the use of the source waters at the IWTF (storm water and IWW) for indirect potable reuse (IPR) and groundwater storage. Each of the 3 SAFER Project components will contribute to increased storm water seasonal storage and storm water and industrial wastewater conveyance for beneficial reuse by Pure Water Monterey (PWM) or the existing tertiary treatment facilities for agricultural irrigation through augmentation of existing infrastructure: 1. The 33-inch pipeline rehabilitation will utilize an existing, abandoned-inplace industrial wastewater pipeline to allow separate gravity conveyance of storm water directly to Pond 1, providing energy savings at the IWTF influent pump station by negating the need to aerate the storm water; this will also facilitate capture of an additional AFY of storm water prior to discharge into the Salinas River water quality + flooding benefits 2. The Blanco Retention Basin (Basin) upgrades will enhance existing infrastructure for more optimal control of storm water levels to protect nearby farmland from flooding and manage water flow for reuse 3. The influent pump station and electrical cabinet improvements will protect critical existing infrastructure from large storm events and right-size pumps, enabling continued, optimal operation of the IWTF for multiple water resource and environmental benefits Reliable, flood-resilient operations of the IWTF and Basin and rehabilitation of the 33-inch line for conveyance of storm water separate from the IWW will increase the ability to capture and beneficially reuse industrial wastewater and storm water through the PWM Project and the existing tertiary treatment facilities for 6

7 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. Promote public education about water supply issues and needs. Promote planning efforts to provide emergency drinking water to communities in the region in the event of a disaster. Water Quality Goal agricultural irrigation. The utilization of additional industrial wastewater, agricultural runoff and tile drainage, and storm water for agricultural and indirect potable reuse will enable unprecedented water supply diversification in Monterey County, which has traditionally relied on surface and groundwater supplies due to isolation from federal and state water projects. SAFER Project components will increase the ability to manage and capture storm water runoff as explained in the preceding responses. Improvements will additionally enhance the site s functionality, resulting in better control and reductions in constituent loading to surface and groundwater in the region. The AFY of additional storm water yield facilitated by the pipeline rehabilitation correlates to reduced discharges into the CWA Section 303(d)-listed Salinas River to the betterment of: 1. Surface water quality in the River, Lagoon, and Monterey Bay National Marine Sanctuary; 2. Downstream flooding conditions; 3. Special-status species habitat including for the S-CCC Steelhead, California Red Legged Frog, and others 4. TMDL/NPDES Phase I Storm Water Permit compliance. By enhancing the amount of storm water yield by the SSW Projects, SAFER will increase the amount of water available for indirect potable reuse by PWM. PWM takes advantage of and optimizes existing conjunctive use infrastructure. SAFER Project components are complimentary to the PWM Source Waters Projects and the City/M1W joint Prop 1 Storm Water Grant Projects which will ultimately provide potable water supply for the Monterey Peninsula, as well as additional irrigation water for the existing tertiary facilities for agricultural reuse. The SAFER Project is critical to ensuring continued operation of the IWTF to accept wastewater from the industrial dischargers, the majority of which are agricultural processors that wash and bag produce (i.e. bagged lettuce). SAFER will assist in the City s continued operation of IWTF for this purpose, as well as for the capture and management of additional source water for agricultural irrigation in the Castroville Seawater Intrusion Project area. SAFER will provide additional source water for the following water recycling projects: 1. The Salinas Valley Reclamation Project and Castroville Seawater Intrusion Project- assist M1W in maintaining continued, reliable recycled water production to supplement groundwater pumping in seawater-intruded coastal aquifers which are the sole source of drinking water for communities like the City of Salinas and Castroville both of which are comprised of disadvantaged communities (DAC) 2. Pure Water Monterey Groundwater Replenishment- create a drought reserve of up to 1,000 AF for use by Monterey Peninsula water ratepayers during droughts or other supply shortages. This also gives M1W and water resource managers greater flexibility to select the best beneficial reuse of Treatment Plant influent depending on circumstance. For example, in the scenario of a water supply shortage during peak irrigation season, Monterey Peninsula Ratepayers could draw from the drought reserve, allowing more influent to be treated for agricultural irrigation. 3. Some additional percolation to the Salinas Valley Groundwater Basin shallow aquifers is also anticipated which may assist in protecting the groundwater basin. 7

8 Promote practices necessary to meet, or where practicable, exceed all applicable water quality regulatory standards (for drinking water, surface and groundwater quality). By enhancing the performance of storm water and industrial wastewater infrastructure, SAFER will reduce discharges of storm water to the Salinas River (California Water Authority (CWA) Section 303(d) listed) by AFY, to the benefit of Salinas River and lagoon water quality, downstream habitat and flooding conditions, and the Monterey Bay. Storm water captured by the project will contribute to the City of Salinas compliance with its NPDES Phase I Storm Water Permit and prescribed TMDLs. Maximizing that amount of both storm water and industrial wastewater M1W can beneficially reuse at this site will significantly reduce constituent loads entering the River, lagoon, the Salinas Valley Groundwater Basin, and the Monterey Bay. Potential reuses include: 1. (Agricultural reuse) Salinas Valley Reclamation Project and Castroville Seawater Intrusion Project- water supply supplement to groundwater pumping in the Salinas Valley Groundwater Basin, threatened by seawater intrusion and future sea level rise 2. (Indirect potable reuse) Pure Water Monterey- water supply replacement for diversion from the Carmel River for habitat preservation and the development of a drought reserve in the Seaside Groundwater Basin for future water supply shortages due to drought. PWM will assist in compliance with State Orders (WR amended by WR ). 3. (Groundwater Recharge) Some additional percolation to the Salinas Valley Groundwater Basin shallow aquifers is also anticipated which may assist in protecting the groundwater basin. Promote projects to prevent seawater intrusion. Incorporate or promote principles of low impact development where feasible, appropriate, and cost effective. Protect surface waters and groundwater basins from contamination and the threat of contamination. Support research and pilot projects for the co-management of food safety and water quality protection. Improve septic systems, sewer system infrastructure, wastewater treatment systems, and manure management programs to prevent water quality contamination. Support research and other efforts on salinity management. Support monitoring to better understand major sources of erosion, and implement a Please see above. Since 2014, M1W has partnered with the City and Monterey County Water Resources Agency (MCWRA) to utilize the IWTF wastewater to supplement lower-than-average urban wastewater flows that would typically supply the Salinas Valley Reclamation Plant and Castroville Seawater Intrusion Project. Ensuring the continued, reliable operation of the IWTF through the SAFER Project will promote those existing projects targeted at slowing the advance of seawater intrusion. Please see response to Water Quality Goal #1 above. SAFER Project components are enhancements to storm and industrial wastewater systems to increase flood protection and reduce constituent loads entering the Salinas River, the Salinas Valley Groundwater Basin (SVGB), and ultimately the Monterey Bay by sequestering up to AFY of additional storm water prior to entering surface water bodies and preventing flooding of nearby agricultural land with storm water from the Blanco Retention Basin. 8

9 comprehensive erosion control program. Promote programs and projects to reduce the quantity and improve the quality of urban and agricultural runoff and/or mitigate their effects in surface waters, groundwater, and the marine environment. Promote regional monitoring and analysis to better understand water quality conditions. Support research and utilization of emerging technologies (enzymes, etc.) to develop effective water pollution prevention and mitigation measures, and source tracking. Promote public education about water quality issues and needs. Flood Protection & Floodplain Management Goal Promote projects and practices to protect infrastructure and property from flood damage. Improve flood management infrastructure and operational techniques/strategies. Implement flood management projects that provide multiple benefits such as public safety, habitat protection, recreation, agriculture, and economic development. Develop and implement projects to protect, restore, and enhance the natural ecological and hydrological functions of rivers, creeks, streams, and their floodplains. Support research and monitoring efforts to understand the effects of flooding on transport and persistence of pathogens in food crop production areas. Support management of flood waters so that they do not contaminate fresh produce in the field. Please see above responses. The SAFER Project will facilitate capture and storage of AFY of additional storm water which otherwise would contribute to constituent loads and sediment in the Salinas River. The SAFER Project will contribute storm water yield for the SSW Projects. The SSW Project grant agreement requires M1W and the City to tabulate constituent load reductions from storm water capture and reuse, providing water quality benefits and habitat enhancement in the SVGB and assisting the City in meeting their TMDL requirements. Please see project description. SAFER includes floodproofing measures at the IWTF influent pump station and electrical cabinet, which currently sit within the 100-year floodplain, making them vulnerable to inundation. The Basin upgrades will enhance existing storm water infrastructure and right-size pumps to allow the City to better control the levels of storm water in the Basin to prevent flooding of nearby agricultural land as has occurred in the past. The Blanco Retention Basin upgrades will allow greater operational flexibility and control of the Basin levels during storms. Lack of such controls and a need for these specific upgrades has resulted in flooding of nearby agricultural land by the Basin in the past. SAFER Project components will provide multiple benefits for habitat protection through protecting water quality; agricultural and public safety by flood prevention of agricultural fields; and economic development by ensuring long-term, costeffective operations of the IWTF for continued use by the industrial processors as a wastewater treatment location. SAFER will enable capture, storage and beneficial reuse of additional storm water that would ultimately contribute to constituent loads in the Salinas River, lagoon and Monterey Bay National Marine Sanctuary (MBNMS). By rehabilitating the 33-inch pipeline, an additional AFY of storm water will be sequestered and stored on site, reducing constituents that impair the ecological functions of the Salinas River and impact special-status species. Please see Flood Protection & Floodplain Management Goal #2 above. 9

10 Promote public education about local flood management issues and needs. Environment Goal Support science-based projects to protect, improve, enhance, and/or restore the region s ecological resources, while providing opportunities for public access and recreation where appropriate. Protect and enhance state and federally listed species and their habitats. Minimize adverse environmental impacts of water resource management projects. Support applied research and monitoring to better understand environmental conditions, environmental water needs, and the impacts of water-related projects on environmental resources. Implement fish-friendly stream and river corridor restoration projects. Reduce adverse impacts of sedimentation into streams, particularly from roads and nonpoint sources. Promote efforts to prevent, control, reduce, and/or eradicate high priority invasive species. Promote native drought-tolerant plantings in municipal and residential landscaping. The SAFER Project will increase yield of storm water for beneficial reuse by the PWM Project and the existing tertiary treatment projects, enhancing habitat and recreational uses of the River, lagoon, MBNMS, and Carmel River. These SSW Projects (enhanced by SAFER Project implementation) will result in calculable constituent load reductions entering the Salinas River, lagoon, and ultimately the MBNMS. Water quality enhancements at the Salinas River may assist in restoring the ecological integrity and recreational uses of the River. PWM will reduce diversions from the Carmel River, restoring in-stream flows for the CCC-steelhead salmon, CRLF, and other species and improving its recreational and aesthetic public value. The Salinas River, Lagoon, and associated riparian habitats are home to several special status species including the Monterey Gilia, Steelhead Salmon, Smith s Blue Butterfly, and others. SAFER Project implementation and resulting reduced constituent loads from storm water sequestration will protect and enhance habitat thereby protect listed species. The Carmel River is habitat for the CCC-steelhead salmon, CRLF, and other species. By providing additional flows for the SSW Projects, SAFER will contribute to the source water portfolio for IPR on the Monterey Peninsula by PWM. This will enable compliance with State Orders WR , amended by WR , which require reductions in diversions from the Carmel River by the local water purveyor for potable supply. The pipeline condition assessment and rehabilitation will utilize existing infrastructure to reduce energy consumption associated with: 1. Pumping storm water to the IWTF influent pump station- instead it will gravity directly to Pond 1, separate from industrial wastewater; and, 2. Unnecessary aeration of the storm water which will occur per the current design of the Salinas Storm Water Phase 1B (storage and recovery) Project. Instead, the storm water will be separately conveyed to Pond 1, bypassing aeration treatment. Enhancing the ability to sequester storm water and urban dry weather runoff prior to entering surface water bodies will prevent sediments therein from reaching the Salinas River. 10

11 Consider opportunities to purchase fee title or conservation easements on lands from willing sellers that provide integrated water resource management benefits. Ensure adequate funding and infrastructure to manage properties and/or monitor easements. Support research and monitoring efforts to understand the effects of wildfire events on water resources. Regional Communication and Cooperation Goal Facilitate dialogue and reduce inconsistencies in water management strategies/regulations between local, regional, state, and federal entities. Promote dialogue between federal and state regulators and small water system managers to facilitate water quality regulation compliance. Foster collaboration between regional entities to minimize and resolve potential conflicts and to obtain support for responsible water supply solutions and improved water quality. Build relationships with federal, state, and local regulatory agencies and other water agencies to facilitate the permitting, planning, and implementation of water-related projects. Increase stakeholder input and public education about the need, complexity, and cost of strategies, programs, plans, and projects to improve water supply, water quality, flood management, coastal conservation, and environmental protection. Disadvantaged Communities Goal Seek funding opportunities to ensure all communities have a water system with adequate, safe, high-quality drinking water. Coordination and dialogue between the City and M1W currently exists due in part to the Prop 1 Storm Water Implementation Grant Projects. Implementation of the SAFER Project will only increase the healthy relationship which exists between the two entities. In addition, the City and M1W are working collaboratively with the Monterey County Water Resources Agency and local agricultural stakeholders on a continual basis to optimize storm water and wastewater collection, storage and treatment toward increased beneficial reuse of these waters. Please see response to Regional Communication and Cooperation Goal #1 above. The SAFER Project will prevent additional constituents from entering storm water, urban dry weather runoff and industrial wastewater from entering the SVGB, which is a source of potable supply for the City of Salinas and community of Castroville. Project components will further protect municipal potable water supplies thereof by providing additional flows for recycling at the Salinas Valley Reclamation Plant (SVRP) and irrigation in the Castroville Seawater Intrusion Project (CSIP) area, 11

12 Seek funding opportunities to ensure all communities have adequate wastewater treatment. Ensure that disadvantaged communities are adequately protected from flooding and the impacts of poor surface and groundwater quality. Provide support for the participation of disadvantaged communities in the development, implementation, monitoring, and long-term maintenance of water resource management projects. Promote public education in disadvantaged communities about water resource protection, pollution prevention, conservation, water quality, and watershed health. Climate Change Goal Plan for potential impacts of future climate change. Support increased monitoring and research to obtain greater understanding of long-term impacts of climate change in the Greater Monterey County region. reducing groundwater pumping in the aquifers affected by seawater intrusion, slowing its inland migration. Please see response to Disadvantaged Communities Goal #1 above. Additional Storm water capture enabled by the pipeline rehabilitation will significantly reduce the amount of storm water entering the Salinas River (CWA Sec 303(d) listed waterbody). This will enhance the River s water quality and protect downstream water quality in the Salinas River Lagoon. The additional storm water yield will also be used for the tertiary treatment projects for agricultural irrigation which assists in slowing seawater intrusion in the Salinas Valley Groundwater Basin, the shared potable water supply for the melt-billiondollar agricultural economy and municipal supply wells for the City of Salinas and Community of Castroville. SAFER will plan for the following climate change impacts: 1. Drought- in the provision of additional storm water yield for beneficial reuse, the Project will create a drought reserve for Monterey Peninsula water ratepayers as well as additional source water for the tertiary system which relies heavily on limited groundwater supplies. 2. Sea level rise- in the provision of additional source water for the tertiary projects and by reducing tertiary treatment process inefficiencies caused by chemical coagulant use, the Project will assist M1W maintain continued, reliable recycled water production to supplement groundwater pumping in seawater intruded coastal aquifers. Seawater intrusion may be worsened as sea levels rise, and with it the hydraulic pressure from the nearby ocean. 3. Rainfall variability- the project will allow the Salinas Storm Water Projects to maximize storm water yield for seasonal storage and later beneficial reuse 4. Flooding- Project components each contribute to more resilient, floodproof storm/industrial wastewater infrastructure which accounts for the high-intensity storm events predicted under climate change assumptions. Particularly those augments to the IWTF influent pump station and electrical cabinet, which entails relocating these vulnerable structures outside of or above flood areas are especially relevant to climate change mitigation/adaptation planning. 12

13 Support efforts to research alternative energy and to diversify energy sources appropriate for the region, and consider options for using renewable energy where such options are integrally tied to supporting IRWM Plan objectives. Seek long-term solutions to reduce energy consumption, especially the energy embedded in water use, with a goal to reducing greenhouse gas (GHG) emissions Seek long-term solutions to maintain and protect existing pristine natural resources from the impacts of climate change. Address adapting to changes in the amount, intensity, timing, quality, and variability of runoff and recharge. Consider the effects of sea level rise on water supply conditions and identify suitable adaptation measures. In considering ways to address IRWM Plan objectives and implement the Plan, consider where practical the strategies adopted by California Air Resources Board (CARB) in its AB 32 Scoping Plan. Support research and/or implementation of land-based efforts such as carbonsequestration on working lands and wildlands in the Greater Monterey County region. Promote public education about impacts of climate change, particularly as it relates to water resource management in the Greater Monterey County region. Project components each have energy reduction potential: inch Pipeline Condition Assessment and Rehabilitation- will allow gravity storm water conveyance to Pond 1 at the IWTF, reducing energy consumption at the IWTF influent pump station. Will also allow storm water to bypass unnecessary aeration that is required because of comingled conveyance with industrial wastewater, per current design of the Salinas Storm water Projects. 2. Blanco Retention Basin Upgrades- by right-sizing pumps that will include Variable Speed Drives (VSD) and seeking design alternatives to energyintensive treatment techniques for storm water (i.e. rehabilitating the 33- inch line to eliminate the pumping and energy costs of aerating storm water along with IWW). 3. Influent Pump Station Enhancements- replacing existing pumps at the influent pump station with more energy efficient VSD technology. Addressed in Project description and in above responses. Please see response to Climate Change Goal #1 above. 13

14 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. 12. Do you want your implementation project to be considered for Round 1? 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 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 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) 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 14

15 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 SAFER Project seeks to ensure long-term multi-functionality of existing storm water and industrial wastewater infrastructure by protecting them from flooding and by enhancing the ability of said systems to capture, store, and convey waters for multiple water resource and environmental benefits. Additionally, rehabilitation of the 33-inch line for transporting storm water directly to the Pond 3 Pump Station, separate from industrial wastewater, will reduce pumping and energy demand and costs associated with aerating comingled storm water and industrial wastewater. A secondary benefit to rehabilitating the 33-inch line for this purpose is that it will allow better integration with regional efforts to vet passive water quality treatments for agricultural and industrial wastewater by removing the influence of storm water. Increased storm water flows facilitated by the SAFER Project will be used at the Advanced Water Purification Facilities (AWPF) for the PWM drought reserve component. The drought reserve utilizes excess flows during low recycled water demand periods (i.e. during the wet season) to run the AWPF at its peak capacity to bank water in the Seaside Groundwater Basin. In dry years, Monterey Peninsula urban water users can pull from this bank to enable M1W to divert source water flows to the SVRP for agricultural irrigation supply, providing flexibility for local water resource managers in future drought conditions. SVRP produces advanced- tertiary water for irrigation of 12,000 acres of agricultural land in the northern Salinas Valley through the CSIP distribution system. Conversely, during periods with intense storm events, SAFER Project components will enhance IWTF and City stormwater infrastructure flood resiliency, ensuring the continuous ability to convey and treat industrial wastewater flows and control of storm water infrastructure to reduce the incidence of flooding of adjacent agricultural land. b) Does your project consider the effects of sea level rise on water supply conditions and identify suitable adaptation measures? c) Does the project take into consideration changes in the amount, intensity, timing, quality and variability of runoff and recharge? Yes, the SAFER Project impetus is to enhance existing infrastructure for maximum stormwater capture for beneficial reuse and to ensure the resiliency of the infrastructure during major storm/flood events. This includes: 1. Right-sizing influent pump station equipment to account for potential future storm water flows; 2. Increasing the French drain collection piping in the Blanco Retention Basin (BRB) to facilitate additional flow; 3. Rehabilitating the 33-inch industrial wastewater line as a means to enhance storm water capture and storage and dewatering capability; and, 4. Floodproofing the existing IWTF influent pump station electrical cabinet to ensure resilient industrial wastewater conveyance and treatment during intense storm events. 15. Reduction of Greenhouse Gas Emissions (GHGs) a) Please describe the extent to which your project will help reduce GHGs, compared to project alternatives. To assist you in estimating GHG emissions, please use the California Emissions Estimator Tool (CalEEMod) on the Greater Monterey County IRWM website: Newer pumps at the Blanco Retention Basin and the influent pump station will incorporate Variable Speed Drive 15

16 technology which is more energy efficient than those currently in place. New controls and metering devices on the aeration basin, coupled with the relevant pumps, will enable optimized use of existing on-site solar energy. Allowing storm water to bypass unnecessary aeration by rehabilitation of the 33-inch pipeline, M1W estimates that there could be a 10% reduction in the overall energy consumption of the IWTF influent pump station. b) If appropriate, describe the extent to which the project will help the region reduce GHGs 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? By eliminating unnecessary aeration treatment of storm water by enabling separate conveyance to Pond 3, M1W estimates that there could be a 10% reduction in the overall energy consumption of the IWTF influent pump station. Current design of the Salinas Storm water Projects dictates that storm water will be comingled with industrial wastewater, requiring aeration treatment. Storm water flows will ultimately be conveyed to M1W s Treatment Plant for beneficial reuse as potable water supply or for agricultural irrigation. SECTION III. PROJECT AND BUDGET NARRATIVE 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. Problem Statement: The Salinas Valley has a range of high priority water supply and water quality challenges including surface water quality impairments that impede meeting environmental and fisheries needs, and groundwater pumping limitations as a result of long-term overdraft in the Salinas Valley Ground Water Basin (SVGB) which has spurred seawater intrusion and threats to municipal potable water supplies. In an era of climate change uncertainty, California has set statewide goals for increasing regional self-reliance and integrated water management. The Salinas Area Flood Enhancements and Reuse Project (SAFER) is a series of improvements to the City of Salinas existing Industrial Wastewater Treatment Facility (IWTF) and storm water infrastructure to enhance operability for water resource, environmental, and water supply benefits. Currently, the City s IWTF and certain components of City storm water infrastructure would benefit from upgrades to be more resilient in large storm events and should be more optimally designed to harness the potential of these climactic events for maximum benefit. The SAFER Project makes necessary improvements to this infrastructure to address the following challenges: 1) Reduce the incidence and likelihood of flood inundation of nearby areas from the Blanco Retention Basin- In the past, productive farmland located adjacent to the Basin has become flooded due to poor operational control of the storm water levels during large storm events. The Basin receives excess flows if the capacity of the City s Salinas River Storm Drainage Pump Station is reached. In these instances, flows are stored temporarily in the Blanco Detention Basin, which has a capacity of 36 ac-ft with freeboard, and up to 50 ac-ft when the freeboard is used and the basin is completely full. 2) Eliminate the influent pump station electrical as the single point of failure of the IWTF- By upgrading the influent pump station and by relocating the associated electrical cabinet above base flood levels, the IWTF system will be more resilient to heavy rainfall. The IWTF is located directly adjacent to the Salinas River within the 100-year floodplain and requires these upgrades to ensure the system operability to protect water quality in the Salinas River by preventing direct discharge of industrial wastewater, but also to 16

17 ensure that industrial processors, mostly agricultural food processing based, that contribute to the IWTF influent are able to continue operations year-round. 3) Increase the yield of the SSW Projects for beneficial reuse and flexible water resource management- In addition, SAFER increases the yield of the SSW Projects for both indirect potable reuse through the Pure Water Monterey Project as well as for CSIP crop irrigation. Notably, the condition assessment and future utilization of the 33-inch line to separately convey storm water to Pond 3 for storage and later recovery for beneficial reuse, will increase storm water yield of the SSW Projects by ac-ft/year. This modification is also expected to reduce energy demand by eliminating needless storm water aeration as is necessitated in current SSW Project design. Additional yield will contribute a portion of the necessary flows for PWM s drought reserve component, which will build 1,000 ac-ft of banked water in the Seaside Basin for future drought scenarios. The drought reserve could be utilized by Monterey Peninsula urban water users to enable flows normally dedicated to the AWPF for PWM, to be directed to the SVRP for increased recycled water yield for crop irrigation. This would enhance groundwater resources in the Salinas Valley Groundwater Basin (SVGB), the shared potable water supply of agricultural and municipal users including the City of Salinas and Community of Castroville (disadvantaged communities [DAC], per the Department of Water Resources). 4) Protect and enhance water quality for beneficial uses- The City of Salinas is a regulated Phase 1 Municipal Separate Storm Sewer System (Phase I MS4) under the National Pollutant Discharge Elimination System (NPDES) and achieves compliance via a watershed based approach. The SAFER Project will contribute to the City s ongoing MS4 compliance by reducing the flow of storm water and agricultural constituents upstream of the Monterey Bay National Marine Sanctuary (MBNMS) by providing additional capacity for capture of storm water for additional treatment. Reductions in the amount of storm water discharged through the City s MS4 system to the CWA Section 303(d) listed Salinas River and ultimately to the MBNMS will contribute to compliance with the Salinas River Total Maximum Daily Loads (TMDLs) for several constituents including fecal coliform, nitrate, pesticides, E. coli, and turbidity, protecting the River s designated beneficial uses for aquatic habitat, municipal and domestic water supply, groundwater recharge, and agricultural supply. In summary, the SAFER Project will: leverage the use of existing infrastructure to improve water quality and assist in regional climate change adaptation; improve regional water self-reliance by contributing to drought-resistant water supplies including PWM and CSIP; increase storm water capture and treatment facilitated by the SSW Projects; increase subsurface water storage to offset groundwater reliance and develop a drought reserve for future drought; decrease seawater intrusion into the SVGB by providing additional influent to M1W s Regional Treatment Plant for regional agricultural use; and overall assist in improving water quality entering to the Monterey Bay National Marine Sanctuary by reducing the amount of storm water discharging to the upstream Salinas River. Project Description: The Salinas Area Flood Enhancements and Reuse Project (SAFER) is a series of improvements to the City of Salinas existing Industrial Wastewater Treatment Facility (IWTF) and storm water infrastructure with the ultimate goal of increasing the functionality of these facilities for multiple water resource and environmental benefits. The Blanco Retention Basin (Basin), located adjacent to Monterey One Water s (M1W) Salinas Pump Station (SAPS), requires upgrades to its subsurface french drains, pump, and piping to increase flood protection of nearby farmland by enabling the City to control the Basin with greater reliability and for improved water quality and water reuse yields (see Figure 1. Concept Site Plan- Blanco Retention Basin). SAFER also includes floodproofing measures to the IWTF electrical cabinet and pump station (see Figure 2. Concept Site Plan- IWTF Influent PS and Electrical Cabinet). Currently, the electrical cabinet and influent pump station are located within the 100- year floodplain, making them vulnerable to inundation during large storm events. Additionally, if the IWTF influent pump station capacity is enhanced, the facility can better accommodate the full flows of storm water available for capture and beneficial reuse by M1W in its recycling operations at the Treatment Plant. M1W and the City are implementing the Salinas Storm Water (SSW) Projects under a SWRCB Prop 1 Storm Water Grant that 17
