Requested Rank Project Description Funds Cost Share TOTAL Resource The Resource Conservation District of Monterey County (RCDMC), in close partnership Conservation with University of California Cooperative Extension Crop Advisors and USDA Natural District of Resources Conservation Service will provide a comprehensive bilingual on-farm erosion, Monterey County: irrigation and nutrient management assistance program for Monterey County farmers. Monterey County The service will continue and build upon previous work that has been performed by the Farm Nutrient RCDMC that 1) evaluates erosion potential, irrigation system and application efficiency, Management and and nutrient budgeting; 2) develops recommendations as needed for field Water Quality configuration, soil stabilization, and refined water and nutrient applications; and 3) Assistance assists growers’ voluntary implementation of those recommendations to help reduce Program excess soil, water and nutrient movement off area farms while optimizing farm productivity. We expect to have implemented the following projects within the grant timeline: 10 strawberry ranches implementing a mix of furrow alignment and grassed farm roads to reduce soil loss on sloped ground, and furrow cover crops to increase infiltration and reduce sediment loss; 4 water and sediment control basins or other tailwater capture and treatment systems; 6 ranches with underground outlets for erosion prevention; and 15 ranches implementing nutrient and irrigation management changes such as pumping/irrigation system improvements, utilization of ET or soil 1 moisture monitoring systems, and improved nutrient budgeting. $351,288 $365,262 $716,550 Central Coast The Salinas Water Quality and Agricultural Reuse Efficiency Project is proposed to occur Wetlands Group, at the Salinas Industrial Wastewater Treatment Facility (IWTF), a treatment facility and Monterey One its associated conveyance system that serves approximately 25 agricultural processing Water, City of and related businesses, owned and operated by the City of Salinas. The IWTF is also the Salinas: Salinas implementation site for the Salinas Storm Water (SSW) Projects, a partnership between Water Quality and the City and Monterey One Water funded through a Proposition 1 Storm Water Grant. Agricultural Reuse The Storm Water Projects will augment and repurpose the IWTF to seasonally capture Efficiency Project and store urban storm water and dry weather runoff for diversion to M1W Treatment Plant (TP) during summer months when recycled water demands are higher. The Project will include two distinct components: 1. Passive Water Quality Enhancement Constraints Analyses and Pilot Study: The initial treatment system will consist of a treatment wetland chamber (with enhanced linear flow) in series with three phosphate removal chambers. 2. 33-inch Abandoned-in-Place Pipeline Assessment and Rehabilitation: During preliminary design of the SSW Projects, the 33-inch pipeline (abandoned-in-place) was identified as an opportunity to utilize existing infrastructure to achieve energy savings if it could be used to separately convey storm water to Pond 1 directly, bypassing the influent pump station and aeration basin. Allowing storm water to bypass unnecessary aeration would result in an estimated 10% reduction in the overall energy consumption 2 of the IWTF. $825,000 $825,000 $1,650,000 Monterey One The Salinas Area Flood Enhancements and Reuse Project (SAFER) is a series of Water: Salinas improvements to the City of Salinas’s existing Industrial Wastewater Treatment Facility Area Flood (IWTF) and storm water infrastructure with the ultimate goal of increasing the Enhancements functionality of these facilities for multiple water resource and environmental benefits. and Reuse (SAFER) The Blanco Retention Basin, located adjacent to Monterey One Water’s (M1W) Salinas Project 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. 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. 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. 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. Allowing storm water to bypass unnecessary pumping and aeration, would result in an estimated 10% reduction in the overall energy consumption of the IWTF. 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 200-300 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 2 increased use of the IWTF storage. $2,535,000 $2,535,000 $5,070,000 Elkhorn Slough The Ridgeline to Tideline project is a comprehensive approach to addressing water National Estuarine resource issues in an estuarine watershed. The three phases of this work include: 1) Research Reserve: restoring ecosystem function in tidal wetlands of Elkhorn Slough with consistently poor Elkhorn Slough water quality, coupled with restoration of an adjacent upland buffer, 2) acquiring Ridgeline to properties that are chronic sources of Slough degradation, and 3) re-contouring and Tideline stabilizing their steep eroding slopes with native vegetation. Reduced groundwater extraction on these lands will improve water balance in the basin, resist sea water intrusion, prevent nitrate pollution, promote freshwater spring re-emergence and 3 sequester carbon. $7,500,000 $7,500,000 $15,000,000 Central Coast This project will negotiate the purchase or conservation easement on 30 acres of un- Wetlands Group: farmable lands east of rail road tracks in the Moro Cojo Slough, to be linked with Ag Restoration of the Trust conservation lands in main channel. We will return fresh water to those lands, Upper Moro Cojo with appropriate buffer from ag operations. We will also install a wetland treatment 4 Slough system on Calcagno land adjacent to drainage and document improved water quality. $500,000 $500,000 $1,000,000 Monterey County The proposed interlake tunnel would be a gravity flow water conveyance tunnel Water Resources approximately 12,000 feet (2.3 miles) long connecting the Nacimiento and San Antonio Agency: Interlake Reservoirs. Conceptual design envisions a reinforced concrete lined tunnel with an Tunnel and inside finished diameter of 10 feet and a slope from Nacimiento to San Antonio of Spillway approximately -0.4 percent. The tunnel will be designed to accommodate internal Modification pressures and seismic activity in the region. The proposed modification to the spillway Project at the San Antonio Reservoir would provide up to a 7-foot increase in the maximum lake 4 elevation, effectively increasing the storage capacity of the reservoir. $60,000,000 $30,000,000 $90,000,000 Central Coast The first objective of the project is to negotiate a land agreement on 10 acres of land Wetlands Group: adjacent to North Espinosa Lake to allow seasonal flooding. This 10 acre addition will Espinosa Lake help optimize winter flood attenuation and spring water supply. The second objective is Flood Retention to modify flood management expectations with adjacent land owners and flood Project management infrastructure as needed to flood Espinosa Lake with 5 ft of seasonal storm water (approximately 850 acre feet). Finally, the third objective is to construct a sinuous drainage system to treat lake waters for beneficial reuse. This will be accomplished by the construction of containment berms, flood conveyance and water treatment channels. The drainage system will be a treatment wetland planted with California native plants that will improve surface water quality through a 50% reduction in nitrate and a decrease in suspended sediment and organic matter. There are also possible recreational opportunities including a walking trail and/or nature viewing 5 locations in the newly improved freshwater habitat. $1,250,000 $1,250,000 $2,500,000 City of Salinas: Completion of design/construction of a green/complete street for an approximate 1/3 Lincoln Avenue mile length of Lincoln Street, Salinas, between Alisal and Market Streets. The project Green/Complete design will include multiple community, water resource and other environmental Street benefits. The concept design, initial sizing, initial quantified performance and cost have been completed. The project will be integrated with the City’s Regional Surface Transportation Program grant for Complete Streets and includes retrofit of the existing street condition to integrate green infrastructure elements such as 5 bioretention/biofiltration and permeable pavement. $1,290,000 $140,000 $1,430,000 Salinas River The Salinas River Multi-Benefit Stream Maintenance Program works to provide 5 to 7- Management Unit year recurrence level of flood risk reduction for the Salinas River and three tributaries. Association, The program is operated by the Salinas River Management Unit Association, the Resource Resource Conservation District of Monterey County and the Monterey County Water Conservation Resources Agency. The program seeks to improve flood protection and channel capacity District of to minimize the potential for flood damages to adjacent lands and public and private Monterey County, infrastructure. The program focuses on vegetation management, sediment removal, and and Monterey arundo and tamarisk removal in 127 permitted maintenance channels along 92 linear County Water miles of the river. The 127 maintenance channels are designed to carry flood flows away Resources Agency: from levees, decrease velocities in the low flow channel and return geomorphic Salinas River Multi- processes to the channel of the Salinas River. Maintenance activities are evaluated Benefit Stream during and after flow events through water surface elevation, depth and velocity of Maintenance inundation, and duration of inundation. The program seeks to reduce flood frequency in Program order to maintain agricultural viability and protect prime farmland that is important to the economy and food supply of Monterey County and the nation. The program promotes natural hydrologic and geomorphic processes that support steelhead migration and floodplain use, while reducing impacts of potential stressors such as stream velocity, stream temperature and floodplain stranding of fish. The program also protects, creates and manages a mosaic of habitat types and structures across the Salinas River floodplain to support a suite of native wildlife species, while reducing stessors such as invasive plant infestations and avoiding loss of uncommon. Important riparian and wetland habitat types. Costs for maintenance are paid for by landowners and operators in the Salinas River Management Unity Association including equipment, labor and permit reporting costs for annual maintenance. Program administration fees and project mapping and modeling efforts could be benefited by funding through the 5 IRWMP program. $370,000 $375,000 $745,000 Castroville The Castroville Water Supply Line Tank and System Improvements Project will provide a Community connection from the new Cal-Am desalination facility to the Castroville Community Services District: Services District’s potable water distribution system to off-set the demand on the Castroville Water deteriorating groundwater supply on which it currently relies. This new, high quality, Supply Line Tank reliable supply will be used to off-set the water currently supplied by the District’s and System groundwater wells which are of relatively poor quality. Levels of chlorides steadily Improvements increased due to seawater intrusion in Well No.3, to the point that as of April 2018 it Project does not meet 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. Total annual supply of 680 acre-feet per year (AFY). Water purchased from Cal-Am not utilized directly in the distribution system will be stored in the District's two storage 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 6 North County Fire Protection District of Monterey County. $3,501,000 $2,800,000 $6,301,000 Central Coast This project will purchase or put an easement on 20 acres of un-farmable land along the Wetlands Group: Old Salinas River Channel between the Salinas River lagoon and the Moss Landing Restoration of the harbor. Fish-friendly channel and wetland restoration activities will then take place to Old Salinas River increase the capacity of the channel to handle higher flows, improve habitat, and 6 Channel improve water quality by treating the farm runoff prior to entering the channel. $740,000 $740,000 $1,480,000 Ecology Action: The Monterey Bay Friendly Landscaping (MBFL) recognition and incentives program Monterey Bay- supports Monterey Bay-area landscape contractors, public agencies, and water utilities Friendly in retrofitting existing landscapes to comply with state and local water efficient Landscaping landscape ordinances (WELO) and storm water post-construction requirements. The Program goals of the MBFL program are to reduce landscape irrigation demand from local water supplies, reduce storm-water run-off and non-point source pollution, and create green urban environments resilient to drought and climate change. To achieve these goals, the MBFL program consists of three components designed with a community-social based marketing approach: 1. Bilingual workforce training in Monterey Bay-Friendly Landscaping design, installation, and maintenance standards through the Monterey Bay Green Gardener Certification Program, and listing of certified Green Gardeners on the public website www.green-gardener.org. 2. Rebate and direct installation incentives to assist property owners and landscape professionals to implement MBFL landscape retrofit projects such as turf replacement with low-water use plants and low-volume irrigation, storm-water run-off redirection to rain gardens and bioretention features, active rainwater harvesting, replacement of impervious surfaces with permeable pavements, and code-compliant greywater irrigation systems. 3. MBFL branding and marketing collateral that assist certified Green Gardeners and landscape industry workers, water utility and public agency staff, and Master Gardeners to market the MBFL watershed approach to landscape design and maintenance, including bilingual landscape maintenance agreements, yard recognition signs and discounts to local ecological landscape supply businesses for property owners that meet 7 MBFL standards. $306,353 $310,000 $616,353 Monterey County MCWRA has developed a Salinas River Long-Term Management Plan (LTMP) to help Water Resources solve complex management challenges on the Salinas River. It is MCWRA’s intent that Agency: Salinas this LTMP be the first step in a process to establish comprehensive solutions to water River Water resource management along the Salinas River. MCWRA intends to develop this Resource management strategy in partnership with all interested parties to meet the goals and Management and objectives for the entire system, while maintaining necessary flexibility. This multi- Habitat benefit management program will address needs related to MCWRA facilities and Improvement operations, as well as related issues such as flood risk reduction, water supply, water Project quality, natural resource conservation, threatened and endangered species 7 management, and federal and state Endangered Species Act compliance. $1,000,000 $2,350,000 $3,350,000 Resource Wildlife habitat, flood control, and water availability on the Salinas River are Conservation compromised by invasive nonnative plants. As of 2011, the Salinas River had the second- District of largest infestation of the noxious weed Arundo donax (arundo) in the state. In 2014, the Monterey County: Resource Conservation District of Monterey County began an ambitious multi-year Salinas River program to eradicate arundo, control other nonnative woody plants (primarily tamarisk Habitat and tree tobacco), and track and encourage revegetation with native species in the Stewardship Salinas River watershed. To date, we have treated 500 net acres of arundo and scattered Program woody nonnatives from San Ardo to Soledad, and we are beginning to see regrowth of native herbaceous and woody species. However, arundo is known to resprout even after multiple rounds of herbicide treatment, and can take many years to fully eradicate. Due to the fast growth rate of arundo (up to 4” per day), arundo stands could quickly recover their former extent and dominance if treatments are not continued. We propose to use IRWM funds to monitor and re-treat arundo and other woody nonnatives over three years within the cumulative footprint of arundo control work that will have been done under other funding sources by the end of 2019. Additional federal funding will support revegetation in treated areas and further arundo treatment in new areas. Re-treatments will be done by hand with a combination of glyphosate and imazapyr in formulations that are safe for aquatic use. By preventing the reestablishment and spread of arundo and other woody nonnatives, this project will protect the $5 million investment made by state and local funders to control invasive plants in the Salinas River watershed, and 8 enable the recovery of the ecosystem. $469,583 $469,583 $939,166 EJCW, in partnership with other members of the DAC Team, will assist small water and wastewater systems in Disadvantaged Communities to plan and implement repairs or improvements necessary to achieve compliance with safe drinking water and wastewater standards and to correct deficiencies that may lead to compliance issues in the future. EJCW and partner organizations will conclude a needs assessment for small drinking water systems through the IRWM DAC Involvement Program in 2019. The assessment will enable the DAC team to develop a priority list of systems in need of repairs or upgrades and determine DAC eligibility through ACS or other methodologies. With Implementation grant funding, EJCW would engage the system managers and Environmental residents in planning solutions to identified deficiencies or incipient problems, secure Justice Coalition professional services for testing and design where needed, coordinate permitting, for Water: Small manage the repair or improvement funding and the construction process and assist in Disadvantaged providing or making referrals for operations and management training. The goal would Community Water be to assist as many small systems with repairs as possible that are ineligible for other and Wastewater funding. All participating systems would receive information regarding water Improvement conservation and energy efficient operations. Depending on funding availability, a water 9 Project conservation kit would be made available to each household in the project. $310,631 $0 $310,631 Monterey County Water Resources Agency: Through a qualitative, quantitative, policy and water rights analysis of streamflow and Integration and reservoir operations, this project will identify the how reservoir operations at Reoperation of Nacimiento and San Antonio reservoirs, river diversions along the Salinas River, and Nacimiento and groundwater extractions in the Salinas Valley impact instream flows in the Salinas River. San Antonio The analysis will then be used to develop a water management plan that considers all 10 Reservoirs the necessary uses for this water. $1,200,000 $1,420,000 $2,620,000 Ecology Action: The WaterLink direct installation program installs water-efficient equipment in homes, WaterLink schools, and businesses in DAC areas to help DAC residents save money on their water Program and energy bills. WaterLink makes it easy for residents to save water and energy by installing low-flow 0.8-1 gpf toilets, 1.5 gpm showerheads and kitchen faucet aerators, 1 gpm faucet aerators, ENERGY STAR most-efficient clothes washers and dishwashers, and fixing leaks in-single family and multi-family homes. The WaterLink program targets commercial kitchens to install high-efficiency pre-rinse spray valves, 0.5 gpm lavatory faucet aerators, and ENERGY STAR commercial dishwashers. Weatherization programs typically restrict participation based on income qualification, which can be a barrier. The WaterLink program does not ask for income verification, but instead allows any household or business to participate within a DAC census tract. Residents become WaterLink participants through connections with public schools and community canvassing in low-income areas with older housing/commercial building stock. During direct installation visits, WaterLink connects participants with additional resource 10 conservation programs they may qualify for. $500,000 $25,000 $525,000 Monterey County The project will replace the existing 42-foot Davis Road low-level bridge over the Salinas Resource River with a 1700-foot bridge and widen the 2.1 mile stretch of Davis Road, between Management Blanco Road to Reservation Road, to 4-lanes. A goal of the project is to minimize the Agency: Davis flooding potential of this vital transportation artery between Salinas and the Monterey Road Bridge peninsula. The new bridge will span the entire floodway of the Salinas River and provide Replacement and a year-round river crossing. Currently the Salinas River overtops the road during large Road Widening rain events triggering a closure of Davis Road at the river and rerouting of traffic onto to Project Blanco Road or State Route 68. The project will provide new cross-culvert crossings and parallel roadside drainage ditches to collect and transport storm water from the roadway. Once the low-level bridge crossing is removed, the river channel will be 11 restored to match other non-disturbed sections of the Salinas River. $803,400 $63,709,722 $68,546,122 Monterey County The Salinas River Fisheries Enhancement Project has three main purposes: (1) Water Resources population monitoring to quantify the presence of the Endangered Species Act listed Agency: Salinas Oncorhynchus mykiss (steelhead trout) in the lower Salinas River system; (2) monitor River Fisheries river flows to ensure adequate water for fish passage (migration monitoring); (3) Monitoring and monitor water quality to determine habitat suitability. Tasks that identify the presence Evaluation and/or enhance the population of O. mykiss will be performed within the Salinas River Watershed in the Salinas River, the Salinas River Lagoon, the Nacimiento River and the 12 Arroyo Seco River. $2,000,000 $3,000,000 $5,000,000 Monterey County The Water Supply Reliability Project is designed to provide improvements and upgrades Water Resources to Monterey County Water Resource Agency (MCWRA) facilities that provide ground Agency: Water and surface water supplies and flood control to the Salinas Valley.
