Plan of Services
The Specific Plan Land Use Plan (see Figure 6, Conceptual Land Use Plan) establishes the boundaries of four (4) General Plan Land Use Designations: General Commercial (GC), Industrial (I), Open Space (OS), and Open Space - Conservation (OS -C) that are consistent with the General Plan land use designations established by the General Plan Amendment. For planning purposes, the Specific Plan is divided into 10 Planning Areas (PA). A PA is a specific geographic area to which identified Development Standards and Zoning Requirements are uniformly applied.
The net acreage of each PA may vary by as much as 15%, provided that the overall maximum acreages for the Industrial PAs and for the General Commercial PAs within this Specific Plan are not exceeded. Table 1, Land Use Plan Statistical Summary, lists each PA and its representative General Plan Land Use Designation, acreage, and target development intensity by General Plan Land Use Designations.

Changes In Service Providers
This POS identifies the current public services providers for the Project site and the public service providers that would serve the Project site upon LAFCO's approval of the proposed annexation; see Table 2, Current and Proposed Public Service Providers. LAFCO uses a POS to determine whether those agencies potentially affected by the proposed annexation have the capacity to provide necessary public services.
The POS does not constitute, and is not intended to provide, a detailed fiscal analysis of the proposed annexation. The POS broadly considers potential budgetary implications of the annexation action.

The following sections will provide an overview of changes in service providers that would occur upon annexation. Where the provider would change upon annexation, the discussions also assess the potential impact of the proposed annexation on service provider's capacity to provide necessary services. 6 The Project consists of a commercial and industrial development and does not generate a need for additional school facilities. The Project would be required to pay development impact fees to Beaumont Unified School District (BUSD) at the time of issuance of building permits. BUSD would be collect these school impact fees pursuant to Senate Bill 50.
Beaumont Pointe Specific Plan
Plan of Services
Animal Control
Riverside County Department of Animal Services currently provides animal control services for the Project site. The services provided by the Riverside County Department of Animal Services are as follows:
1) Clinic Services: spraying and neutering; vaccinations; low-cost rabies clinics; micro -chipping; quarantine; and euthanizing.
2) Field Services: stray, injured, and dead animal complaints; animal turn -in; cruelty investigations; barking dog complaints; leash law violations; rabies reports; bite reports and quarantines; potentially dangerous, dangerous, and vicious dog hearings; dog license inspection/collect fees; kennel license requires/inspections; emergency response and investigations; subpoenas for records.
3) Shelter Services: adoptions; animal turn -in; animal behavior classes; upkeep of impounded animals; and animal records.
Upon annexation, the City of Beaumont Animal Control Services Department will provide animal control services for the Project site. The Department is responsible for enforcement of State and local animal laws and regulations, including licensing of animals.
A. Implications for Animal Control Services
The City's Fiscal Year (FY) 2023-2024 Budget allocated $385,923 for animal control services'. The proposed annexation would increase the City's size by 2.72 percent and any increased demands for Animal Control Services would be proportionally nominal, as compared to the City. The Project would establish commercial and industrial uses that would not be expected to increase the local animal/pet population.
Animal control services provided to the Project site through the City would be similar to those services currently provided by Riverside County. Mitigation fees, property taxes, and revenues generated by development within the Project site would be available to the City to offset any increased costs for animal control services with little or no net effect on the City's budget (see Attachment B).
Fire Protection
Riverside County Fire Department (RCFD) currently provides fire protection services for the Project site.
Under existing conditions, the Project site places minimal demand on the RCFD because the Project site is undeveloped and vacant. After annexation, the City of Beaumont would provide fire protection services through its contract with the RCFD in conjunction with CalFire for Citywide fire protection, emergency medical services, and fire safety education. As such, the ability and capacity to provide fire protection services would not change upon annexation, only the means of paying for fire protection services.
There are two fire stations within the City limits: Station 66 and Station 20. Station 66, located at 628 Maple Avenue (approximately 3.6 roadway miles east of the Project site), is staffed 24/7 with career firefighters and would provide initial response. Station 66 has one staffed Type 1 engine, one staff Medic squad and can respond within 7 minutes to the proposed entrance of the Project site. Secondary response would be provided from RCFD Station 20, which is located at 1550 E. 6th Street in Beaumont (approximately 5 roadway miles east of the Project site) and can respond within approximately 9 minutes to the Project entrance. Beaumont Station 20 has one staffed Type 1 engine. ' https://city-beaumont-ca-budget-book.cleargov.com/8398/departments/animal-control Beaumont Pointe Specific Plan
Plan of Services
In September 2022, the City commenced the construction of new Fire Station No. 106 (the "West Side Fire Station") along Potrero Boulevard across from Olivewood Avenue. Construction is expected to take approximately twelve months. The new fire station will be approximately 10,000 sq. ft. and will include living quarters, offices, a fitness center and large bays to house multiple fire apparatus. Staffing will include three to four personnel, including a paramedic to provide advanced life support care. Services from the facility will be provided 24 hours a day, 7 days a week and 365 days of the year. Personnel at this station will be equipped with cardiac monitors, advanced life support medications, intubation equipment, trauma life support equipment, auto extrication tools, and more. The apparatus which will be housed in the facility will be capable of suppressing structure, wildland, vehicle, and other types of fires. The new station will decrease response times for the City's west side communities, including Olivewood, Tournament Hills, Tukwet and the new logistics centers located off of SR -60.
According to the RCFD 2016 TriData Report, units should travel to calls within the defined response time goal for the appropriate population density classification 80% of the time. As noted in the report, Station 66 was in compliance of meeting the defined response time 81.4% of the time and Station 20 was in compliance 83.9% of the time. Additionally, areas that have fewer units available or are farther from neighboring stations are more impacted than others by an increase in emergency calls. They have greater workload sensitivity —as the workload increases their ability to meet the demand decreases. Station 66 is considered to have a low sensitivity workload, and Station 20 is considered to have moderate sensitivity, both with the capacity for more workload. Station 106 would absorb a portion of Station 66 and Station 20's call volumes and would be anticipated to have slightly lower call volume than the existing stations.
A. Implications for Fire Protection Services
The City's FY 2023-2024 Budget allocated $6,820,202 for fire protection services8. The Project is estimated to generate approximately 5,456 permanent jobs at Project buildout. The number on site at any given time may likely be half the estimated employee population, due to employee shift work, estimated transient population and operating hours of individual businesses. Based on this information, the total maximum estimated total population (which includes employees and transient use) of the Project site at any given time, is projected to be 2,728 persons.
Based on the assumptions above, the Project development is estimated to increase call volume up to 191 calls per year (4 calls per week or 16 calls per month). In 2021, Fire Stations 66 and 20 had a combined emergency responses of 4,412 calls per year (2,607 and 1,805 respectively), or 7.1 and 4.9 calls per day per station respectively. The level of service demand for the Project raises overall call volume but is not anticipated to impact the existing fire stations to a point that they cannot meet the demand. For perspective, five calls per day are typical in an urban or suburban area. A busy fire station company would be one with 10 to 15 or more calls per day. Upon buildout of the Project site, Fire Station 66 could respond to an additional 4 calls per week, although the number will likely be lower than that based on the conservative nature of the population and calls per capita data used in this estimate. Additionally, with the operational status of new Fire Station 106, estimated to be operational late 2023, call volumes are anticipated to be reduced for the two existing stations and Station 106 should be approximately 5 to 7 calls per day.
Further, all development proposals within the Project site would be subject to Fire Department review.
Department review ensures that the design of proposed developments within the Project site conform to the Department requirements and thereby reduce demands on fire protection services. Additionally, mitigation fees, property taxes, and other revenues generated by development within the Project site would be available to the City to offset any increased costs for fire protection services with little or no net effect on the City's budget (see Attachment B).

Plan of Services
Law Enforcement
The Riverside County Sheriff's Department currently provides police services to the Project site. Under existing conditions, the Project site places no demand on the police department because the Project site is undeveloped and vacant. The Riverside County Sheriff's Department currently provides law enforcement services from the Cabazon Station located at 50290 Main Street, Cabazon, approximately 14.4 miles east of the Project site. This station serves the contract City of Calimesa, the unincorporated pass area around the Cities of Beaumont and Banning, and the unincorporated areas of Cabazon, Cherry Valley, Poppet Flats, San Gorgonio, San Timoteo Canyon, Twin Pines and Whitewater.
The 2006 Municipal Services Review ("MSR") prepared by LSA Associates, Inc. for Riverside County LAFCO estimated that the average response time for the unincorporated areas of Riverside County was
8.08 minutes for priority one calls, 11.92 minutes for priority two calls and 17.34 minutes for priority three calls.
Riverside County's level of service standard for law enforcement calls for 1.2 full-time deputies for each 1,000 residents, with actual staffing levels at approximately .83 deputies for each 1,000 residents per the MSR.
After annexation, law enforcement services for the Project would be provided by the Beaumont Police Department. The Beaumont Police Department Station is located at 660 Orange Ave, Beaumont (approximately 3.6 roadway miles east of the Project site). BPD currently operates with a total of 54 sworn staff members and includes: patrol officers, detectives, and a sergeant; task force members; motor officers; community policing team member; multiple enforcement team members; and a K-9 unit. Based on the most recent budget, a total of three police officers were added for fiscal year 2024, making the total department personnel count at 57 personnel (one of them being detailed as a School Resource Officer being reimbursed by BUSD). Additionally, as of 2022, the BPD staffs a total of 17 non -sworn staff members which includes: two animal control officers (Beaumont); one tribal contract; one support services supervisor; nine dispatchers; three records staff, and one evidence clerk. The number of crimes rose in 2018 and 2019, but decreased significantly in 2020. Similarly, calls for services increased between 2018 and 2019, but decreased in the following year. BPD's response time goal for emergency call is less than 4 minutes and varies based on priority for non -emergency calls. Currently, BPD is meeting this goal with an average response time of three minutes and 56 seconds for emergency related calls. According to BPD's Budget for fiscal year 2024 , the City is currently operating at 1.0 officers per 1,000 population.9 A. Implications for Law Enforcement Services
The City's FY 2023-2024 Budget allocated $16,486,010 for law enforcement services'o. Upon annexation, the Project site would be served by the BPD. Implementation of the Project would result in an increase in calls for service; however, BPD has indicated that this increase would not adversely impact BPD's existing resources. BPD is currently expanding into an additional off -site facility to accommodate growth and develop a downtown bike patrol program. Additionally, BPD has indicated that as the City population continues to grow, BPD is anticipating an 8% increase in sworn personnel and 12% increase in support staffing. With the anticipated increase in staffing, higher ratio of officer per resident, and lower response times on average when compared to the Riverside County Sheriff's Department response times, the City of Beaumont should provide superior levels of law enforcement services for the Project. Moreover, the Project would be required to pay development impact fees to the City to assist in providing future police protection facilities, including police stations.

Plan of Services
All development proposals within the Project site would be subject to Police Department review. Department review acts to ensure that development proposals within the Project site would conform to Department emergency access and site/facility security requirements and recommendations, and thereby reduce demands on law enforcement services. Additionally, property taxes, and other revenues generated by development within the Project site would be available to the City to offset any increased costs for law enforcement services with little or no net effect on the City's budget (see Attachment B).
Library Services
The Beaumont Library District is a special "library services" district and is independent of both City and County governments. The Beaumont Library, located at 125 E. 8th Street (approximately 3.2 roadway miles east of the Project site), currently serves over 80,000 residents in these areas. The library hours are listed below:
Monday, Friday, and Saturday: 10 a.m. - 6 p.m.
Tuesday/Thursday: 10 a.m. - 7 p.m.
Wednesday: CLOSED
Sunday: 1 p.m. - 6 p.m.
Beaumont Library provides services for adults as well as children and teens with a total of 56,745 volumes and has 14,490 registered borrowers utilizing the collections. As of the most recent data published for 2021- 2022, the library circulated approximately 106,424 children's books and adult books, in addition to other items such as DVDs, audio books, and use of library equipment". Currently, the Library building is about 12,000 square feet or 0.17 square feet per capita. Over the last several years, architectural plans and drawings for a building totaling slightly more than 40,000 square feet have been developed.
A. Implications for Library Service
The Project site currently places no demand on the County library system because the Project site is undeveloped and vacant. Upon annexation into the City, the Project site would be served by the Beaumont Library District. The commercial and industrial uses planned for the Project site are not typically sources of demands for library services. Therefore, the proposed annexation would not affect the District's ability to provide library services with no net effect on the City's budget.
Parks and Recreation
Parks and recreation services for the City are provided by the City and the Beaumont -Cherry Valley Recreation and Park District (BCVRPD). The City owns 140.69 acres of parkland and the various Homeowners Associations (HOA) together own and maintain about 142.2 acres. BCVRPD operates approximately 60.5 acres of parks within the City limits, including Noble Creek Park, which includes a 20 - acre sports park a dog park and a one -mile walking trail, and is highly utilized by all sports leagues in the City. BCVRPD also operates the Beaumont Women's Club facility, which supports community activities.
Together with the 60.5 acres maintained by the BCVRPD, there are a total of 343.4 acres of publicly- and privately -owned parkland within the City. The City's current park ratio requirement is 5 acres of parkland (and full improvements) per 1,000 residents. Based on the total acres of all parks and facilities maintained by the City, HOAs, and BCVRPD within the City limits, a total of 343.4 acres of parkland is being provided for a current park ratio of 6.52 acres of parkland per 1,000 residents. Therefore, the City currently exceeds required parkland ratios.

Plan of Services
A. Implications for Parks and Recreation
The City's FY 2023-2024 Budget allocated $1,899,199 for the parks and recreation department12. The nearest existing regional and City -owned parks to the Project site are listed below. • Noble Creek Park (regional park): Noble Creek Community Park, which is located approximately
3.0 miles northeast of the Project site, contains baseball fields, community center, playground, remote controlled car race track, dog park, and tennis court within its approximately 60 -acre site. • City of Beaumont Sports Park (regional park): City of Beaumont Sports Park, which is located approximately 3.7 miles northeast of the Project site contains baseball/softball fields, basketball courts, bike trail, parking, picnic areas, playground, restrooms, snack bar, soccer fields, walking track, and water fountains within its 20 -acre site.
• Palmer Park (City -owned): Palmer Park, which is located approximately 1.3 miles north of the Project site, contains a baseball field, a basketball court, an outdoor grill and picnic area, a playground, and a parking lot within its approximately 5 -acre site. • Trevino Park (City -owned): Trevino Park, which is located approximately 1.5 miles northeast of the Project site, contains a baseball field, a grass field, two basketball courts, an outdoor grill and picnic area, a playground, and parking lot within its approximately 7 -acre site.
The proposed annexation would increase the City's size by approximately 2.72 percent. The commercial and industrial uses planned for the Project site would not substantively increase demands for parks and recreational services. Property taxes and revenues generated by development within the Project site would be available to the City to offset any increased costs for parks and recreational services, with little or no net effect on the City's annual budget.
Roads and Circulation
The Riverside County Transportation Department is currently responsible for providing roads and circulation services for the Project site. The Department provides planning, design, funding, construction, operations, and maintenance for all roads, bridges, and transportation facilities for roads within the unincorporated area of the County. Upon annexation, the City of Beaumont Public Works Division would provide roads and circulation services for the Project site.
A. Implications for Roads and Circulation
The City's FY 2023-2024 Budget allocated $3,606,165 for the public works department13. The Project would construct four main roadways for on -site circulation -4th Street, Jack Rabbit Trail, Entertainment Avenue, and Industrial Way. Jack Rabbit Trail and 4th Street will be public right of way . The precise location of roadways and access points identified in this POS are considered conceptual in that they may be modified to meet the requirements of the City of Beaumont Public Works Department and to address final grading requirements.
• 4th Street would be constructed with a 78 -foot right of way in the southerly portion of the Project site from Jack Rabbit Trail at the easterly edge of the Project site along the north side of Planning Area (PA) 9 to its termination at a cul-de-sac within PA 8. It provides local access to all PAs except 12 https://city-beaumont-ca-budget-book.cleargov.com/8398/departments/parks-and-recreation 13 https://city-beaumont-ca-budget-book.cleargov.com/8398/departments/public-works Beaumont Pointe Specific Plan
Plan of Services
PA 2. At PA 8, 4th Street connects to Industrial Way through a private road, creating a looped road system around the entire site.
• Jack Rabbit Trail road is an existing two-lane road that runs from the Jack Rabbit Trail/SR-60 off - ramp, through the Project site and continuing further south to eventually connect to Gilman Springs Road in the Hemet area. The Project would construct Jack Rabbit Trail road as a 78 -foot right of way and reroute the section of Jack Rabbit Trail road from the SR -60 off -ramp to 4th Street to connect with the existing Jack Rabbit Trail at the south edge of the Project site. Jack Rabbit Trail will provide access to PAs 1 and 2, as well as providing gated, emergency access to the SR -60 Freeway.
• Entertainment Avenue, a private access road,14 would be constructed with a 50 -foot right of way as a curvilinear street connecting Jack Rabbit Trail and 4th Street south of PA 2 and PA 3, on the west side of PA 1. Entertainment Way also provides access to PA 3 along their western edges.
Entertainment Way demarcates the change in land use between the Industrial uses in PAs 3-8 and "The Experience at Beaumont Pointe" in PAs 1 and 2, while connecting Jack Rabbit Trail and 4th Street.
• Industrial Way, a private access road, would be constructed with a 40 -foot right of way, which creates a looped connection from Entertainment Way at the Project's eastern boundary to 4th Street at PA 8. Industrial Way would provide secondary access to each PA. Industrial Way also forms the edge of the open space located in PA 9 to the north, west, and a portion of the south side of the Project.
• An Interim Fire Access Loop would be constructed with a 40 -foot width to provide secondary access to each phase of development, connecting Industrial Way and 4th Street. Each "Interim Fire Access Loop Connection" would be incorporated into the parking for each subsequent phase. For Phase 1, an Interim Fire Access Loop Connection would be constructed between PAs 4 and 5 and would be incorporated into the parking for PA 5 during development of Phase 2. For Phase 2, an Interim Fire Access Loop Connection would be constructed between PAs 6 and 7 and would be incorporated into the parking for PA 7, during development of Phase 3. For Phase 3, 4th Street and Industrial Way would be connected at PA 8 to create a permanent fire and emergency access circulation loop.
• A 20 foot graded dirt road through PA 9 connects the on -site portions of Jack Rabbit Trail to the existing unmaintained County roadway dedicated for Jack Rabbit Trail, which continues off site to the south through the Badlands, where it ultimately connects to Gilman Springs Road. The Project will include construction of a 20 -foot graded dirt road within PA 9 to connect to the realigned Jack Rabbit Trail on site to the existing off -site roadway, and will not be responsible for construction of the road south of PA 9. No access to, use of or development of Jack Rabbit Trail is proposed south of PA 9.
• Additionally, there is one existing ranch property south of 4th Street (Hoy Ranch), which will have access from 4th Street through PA 9.
All traffic/transportation improvements constructed in support of Project site development would comply with City -stipulated design, construction, and operational requirements. This would act to ensure that traffic/transportation improvements are properly designed, implemented, operated, and maintained; thereby furthering efficiency and adequacy of systems while reducing systems lifecycle costs. Additionally, the 14 Private roads are developer/owner maintained.
Beaumont Pointe Specific Plan
Plan of Services
Developer would pay fees pursuant to the incumbent City of Beaumont Fee Schedule to fund plan review, coordination, and inspection of proposed traffic/transportation improvements. Moreover, State funds (i.e., California gas tax), as well as property taxes and revenues generated by development within the Project site, would be available to the City to offset any increased costs for street maintenance, with little or no effect on the City's annual budget (see Attachment B). The Project Applicant would also be required to pay per -unit fee payments associated with the Western Riverside County Transportation Uniform Mitigation Fees (TUMF) and the City of Beaumont Development Impact Fee (DIF), and fair share fees to ensure the implementation of roadway improvements in the area in order to minimize traffic congestion.
Solid Waste
The Riverside County Department of Waste Resources (RCDWR) is currently responsible for providing solid waste management services for the Project site. A description of the active Riverside County Landfills is provided below.
• Lamb Canyon Landfill — Located approximately 4.2 miles southeast of the Project site in City, the Lamb Canyon Landfill is the nearest landfill to the Project site at 16411 Lamb Canyon Road. The landfill is operated by the RCDWR. The landfill has a permitted tonnage of 5,000 tons per day (tpd), plus 500 tpd for beneficial reuse, 19,242,950 cy of capacity remaining as of January 2015, and has an estimated closure date of April 2029. It should be noted that the Lamb Canyon Landfill is currently undergoing a capacity to extend the life of the facility. • Badlands Landfill — Located approximately 4.3 miles northwest of the Project site in the City of Moreno Valley at 31125 Ironwood Avenue. The landfill is operated by the RCDWR. The landfill has permitted tonnage of 4,800 tpd, has a remaining capacity of 15,748,799 cy as of January 2015, and has an estimated closure date of January 2059.
• El Sobrante Landfill — Located approximately 27 miles southwest of the Project site in the City of Corona at 10910 Dawson Canyon Road. The landfill is privately owned and operated under an agreement with Riverside County. The landfill has a permitted tonnage of 16,054 tpd, has a remaining capacity of 143,977,170 cy as of April 2018, and has an estimated closure date of January 2051.
• Blythe Landfill — Located approximately 140 miles southeast of the Project site in the community of Ripley at 1000 Midland Road. The landfill is operated by RCDWR. The landfill has a permitted tonnage of 400 tpd. The landfill has a remaining capacity of 3,834,470 cy as of May 2016 and has an estimated closure date of August 2047.
• Desert Center Landfill — Located approximately 95 miles southeast of the Project site in the community of Desert Center at 17-991 Kaiser Road. The landfill is operated by RCDWR and is only open two days per year. The landfill has a permitted tonnage of 60 tpd, has a remaining capacity of 127,414 cy as of November 2018, and has an estimated closure date of August 2107. • Oasis Landfill — Located approximately 65 miles southeast of the Project site in the community of Oasis at 84-505 84th Avenue. The landfill is operated by RCDWR. The landfill has a permitted tonnage of 400 tpd has a remaining capacity of 433,779 cy as of October 2012, and has an estimated closure date of September 2055.
Beaumont Pointe Specific Plan
Plan of Services
A. Implications for Solid Waste Services
Upon annexation, the City of Beaumont would provide solid waste management services for the Project site. Under existing conditions, there are no portable or temporary buildings on the Project site, and the Project site does not generate solid or liquid wastes that require landfill disposal. Currently, Waste Management, Inc. provides waste collection and disposal services for residences and business within the City of Beaumont. Disposal of the municipal waste including construction waste within the City of Beaumont General Plan Sphere of Influence Area is ultimately the responsibility of the County of Riverside, and the County will direct the waste to any of the available disposal sites. During the Project's construction phases, approximately 11,568 tons of waste would be generated. The California Green Building Standards (CalGreen) Code, which has been adopted by the City's Municipal Code (Chapter 15.22, Green Building Standards Code), requires that at least 65% of construction debris be diverted from landfills through recycling, reuse, and/or salvage. Non -recyclable demolition debris and construction waste generated by the Project would be disposed of at the Lamb Canyon Landfill. Waste Management offers weekly trash, green waste and recycling curbside service. The City's agreement with Waste Management includes a tipping fee for the County's costs to operate the Lamb Canyon landfill. There would be no change in the location for solid waste disposal, only the means of paying for this service. Further, there would be little or no effect on the City's annual budget, so this Plan of Services provides no further assessment of this service.
Stormwater Management
The Riverside County Flood Control and Water Conservation District (RCFCWCD) currently provides stormwater management services for the Project site. The Project site and surrounding areas are currently - unimproved; and there are storm drain facilities in place. Stormwater originating from the Project site drains to the northeast towards SR -60 to 16 existing Caltrans maintained culverts (1-16) via their respective tributary areas (drainage areas 100 thru 1600). Tributaries for these culverts extend to the ridgelines of the Badlands foothills along the southern and northern borders; the development on the eastern border provides a ridgeline for the eastern edge of the Project site. The northwestern most culvert is an existing 54 -inch corrugated metal pipe (CMP) and the southeastern most culvert is a double 48 -inch CMP adjacent to the SR -60 off -ramp for Jack Rabbit Trail. The tributaries feature steep, eroded hillside grades and natural depressed grasslands at the entrances of the culverts. These depressed areas provide natural detention areas for the culverts before the runoff confluences with San Timoteo Creek on the northern side of SR -60.
A. Implications for Stormwater Management
Upon annexation, the City of Beaumont would take on responsibility for local stormwater management and RCFCWCD would continue to provide regional stormwater management services in the area. Onsite storm drain systems would be managed by the property owner. The Project's proposed storm drain system would consist of catch basins, grated inlets, storm drainpipes with sizing varying from 18 -inches to 48 -inches, and four detention basins, each of which provide stormwater treatment and peak flow mitigation for each of their respective tributaries. On -site and some off -site flows would be conveyed within the proposed streets to a series of catch basin and stormwater lines which direct flows to the four on -site detention basins. Detention basins are planned within PAs 4, 5, 6, and 8. It should be noted that the Project's flood protection facilities would be designed in accordance with the requirements of the RCFCWCD with adequate access easements and facilities provided. The Project's proposed stormwater drainage system is designed to accommodate anticipated stormwater flows to accept 100 -year, 1 -hour storm events from the Project site under developed conditions. The Project's stormwater will flow to the existing culverts, drain to San Timeteo Creek Reach 3, then into the Santa Ana River, and ultimately discharge into the Pacific Ocean. No new or expanded off -site storm drain facilities are required to accommodate runoff from the Project site beyond that proposed as part of the Project.
Beaumont Pointe Specific Plan
Plan of Services
All stormwater management systems constructed within the Project site and proposed connections to the municipal stormwater management system would comply with City and RCFC stipulated stormwater management system design, construction, and operational requirements. This would act to ensure stormwater management facilities are properly designed, implemented, operated, and maintained; thereby furthering efficiency and adequacy of systems while reducing systems lifecycle costs. Additionally, the Developer would pay fees pursuant to the incumbent City of Beaumont Fee Schedule to fund plan review, coordination and inspection of supporting stormwater management systems.
Wastewater Collection and Treatment
The Project site currently does not have a public wastewater collection and treatment service provider.
Following Annexation, the Project will be served by the City's wastewater treatment system. The City controls and manages the sewer collection, conveyance, and treatment system. All sewage generated within the City, as well as some unincorporated areas in Cherry Valley, are treated at the Beaumont Wastewater Treatment Plant No. 1. Built in 1929 and most recently upgraded in 2018, the City Wastewater Treatment plant has a permitted capacity of 6.0 mgd of effluent and receives an average daily flow of approximately 3.7 mgd. Additionally, the facility has capacity to deliver 6 mgd of recycled water. The City is obligated to discharge a minimum of 1.5 mgd of treated effluent from the Beaumont Wastewater Treatment Plant No. 1 to Cooper's Creek, a tributary to San Timoteo Creek (Order No. RS -2015-0026).
In November 2020, the City completed its upgrading and expanding of the Beaumont Wastewater Treatment Plant No. 1 capacity. With implementation of the upgrade and expansion, the City increased the permitted capacity from 4.0 mgd to 6.0 mgd, which is anticipated to adequately treat flows generated over the next 20 years.
Recycled water from BCVWD may be provided from the City of Beaumont's wastewater treatment facility in the future. As of 2021, BCVWD has over 44 miles of non -potable (recycled) water transmission and distribution system in place. The backbone transmission system forms a loop around the City and is comprised of primarily 24 -inch diameter cement mortar lined -ductile iron pipe. The system includes a two - million -gallon recycled water reservoir. The nearest recycled water line to the Project site is located along Oak Valley Parkway adjacent to the Golf Club at Tukwet Canyon. The non -potable water system consists of 3 (potentially 4 in the future) pressure zones: 2400, 2600, 2800, and 3000. The 3000 Non -potable Zone will likely not be operational for several years (if ever) as most of the current demand is in the other zones; BCWVD is in the process of analyzing the feasibility of a 3000 -pressure zone.
A. Implications for Wastewater Collection and Treatment Upon annexation, the City of Beaumont would provide wastewater collection and treatment services for the Project site.
The Project is anticipated to have an average dry weather wastewater generation rate of 88,899 gallons of wastewater per day (GPD) with a peak dry weather sewer generation rate of 253,907 GPD or 0.26 million gallons per day (MGD). The Project would construct a wastewater conveyance system to service the Project site and connect to the City's sanitary system. The Project utilizes a gravity sanitary system and lift station.
However, due to the grading limitations, the development's sewer system cannot flow by gravity to the proposed point of connection, which is a 12 -inch PVC line, located at the end of the extension of 4th Street within the adjacent Beaumont Crossroads sewer lift station collection area. Instead, the gravity system will flow to the proposed sewer lift station located at the northwest corner of PA 5. From there the sewer flow will be conveyed via the proposed Dual Force Main within Industrial Way and Entertainment Avenue, and Jackrabbit Trail towards a connection at 41h Street with an existing 12 -inch gravity sewer line. The onsite lift station will be designed and installed to service the development's full buildout conditions. Additionally, the Beaumont Pointe Specific Plan
Plan of Services
existing City owned and operated Beaumont Crossroads sewer lift station will need to be upgraded as part of this Project since the lift station does not current have enough capacity to serve the Project.
The 0.26 MGD of wastewater generated by the Project would be treated at the Beaumont Wastewater Treatment Plant No. 1, which currently has the upgraded capacity to treat 6.0 mgd of effluent. The Project's anticipated wastewater generation represents approximately 4% of the treatment capacity for the Beaumont Wastewater Treatment Plant No. 1. The Beaumont Wastewater Treatment Plant No. 1 has sufficient capacity to treat wastewater generated by the Project in addition to existing commitments.
The Developer would pay fees pursuant to the incumbent City of Beaumont Fee Schedule. These fees would cover the City's cost to fund plan review, coordination, and inspection of proposed wastewater collection system improvements. The Developer would be responsible for any capital costs to extend the existing sewer lines, as well as applicable sewer connection and service fees, which act to fund improvement plans, operations, and maintenance of wastewater collection facilities. The City would be responsible for maintenance of sanitary sewer main lines, while the Developer would bear the maintenance costs for sanitary sewer laterals. The proposed annexation would have little or no net effect on the City's annual budget (see Attachment B).
Water Supply
The BCVWD is the provider of potable and non -potable water to the City of Beaumont and the unincorporated community of Cherry Valley. The Project site is within the BCVWD sphere of influence but outside the BCVWD's service area boundary. Therefore, annexation into the BCVWD service area boundary is required for the Project to proceed. As discussed above, a separate Plan of Services has been prepared for the BCVWD annexation and is attached as Attachment A to this Plan of Services. A brief summary of that Plan of Services is set forth below.
BCVWD provides potable water from two local groundwater sources: Edgar Canyon and the Beaumont Basin. The BCVWD currently owns and operates a total of 24 groundwater wells of which only 20 are used.
The BCVWD's total well capacity is about 27.5 MGD with the largest well out of service which is greater than the current 21.6 MGD maximum day demand. The District has 11 pressure zones and 14 reservoirs (tanks) ranging in size from 0.5 MG to 5 MG. The total storage in the system is approximately 22 MG —just over two average days or just over one maximum day demand. The reservoirs provide gravity supply to their respective pressure zones. The BCVWD's potable system is constructed such that any higher zone reservoir can supply water on an emergency basis to any lower zone reservoir. There are booster pumps in the system to pump water up from a lower pressure zone to a higher pressure zone also.
The Project was previously planned and included in the BCVWD's 2015 UWMP with a land use density of 2,000 equivalent dwelling units (EDUs) (previously identified as Jack Rabbit Trail). Based on the District's adopted EDU usage factor of 0.546 AFY/EDU, this equates to an estimated water demand of 1,092 AFY.
The new Beaumont Pointe Development land use plan, consisting primarily of industrial warehouse buildings along with a 125 -room hotel and general commercial uses, estimates a density of 360.26 EDUs.
The originally approved Beaumont Point Development WSA indicated that approximately 43.31% of the potable water demand from the 360.26 EDUs could be served by BCVWD's Non -Potable Water (NPW) system reducing the Project's potable water demand to 204.21 EDUs or 111.50 acre -ft per year. As part of the Project's Plan of Service documents and ongoing water conservation efforts, the Project will be designed to utilize NPW for all outdoor irrigation demands.
The Beaumont Pointe development project site was included in the list of planned development projects in BCVWD's 2020 UWMP (previously identified as Jack Rabbit Trail) which demonstrated adequate water Beaumont Pointe Specific Plan
Plan of Services
supplies up to the year 2045. To clarify, when the District was preparing the basis for future water demands within the District's service area in the BCVWD's 2020 UWMP, the District utilized the potable water demands from the DRAFT November 2020 Beaumont Pointe WSA. This draft version of the Project's WSA identified the potable water demand as 221 EDUs as shown in Table 3-7 in the BCVWD's 2020 UWMP.
Because the Project's updated land use plan has a potable water demand of 204.21 EDUs, the District's 2020 UWMP conservatively included the Project's anticipated potable water demands at 221 EDU.
A. Implications for Water Supply
Water demand associated with the Project would consist of interior plumbing devices (i.e., sinks, toilets, faucets), and various industrial and commercial process systems. Outdoor irrigation demands will be serviced by the District's NPW distribution system. The Project site is within BCVWD's 2650 Pressure Zone (PZ). The development of the Project would require construction of new water distribution lines within the Project site's development footprint. Additionally, the Project would construct an on -site recycled water system supplied by BCVWD. Recycled water will be used for construction dewatering, irrigation of manufactured and replanted slopes within PA 9, as well as for irrigation of parkway landscaping and irrigation of landscaping within the General Commercial and Industrial land uses (PAs 1-8). The final design and sizing of on -site potable water, fire flow, and non -potable water facilities would need to accommodate the anticipated water demand (landscaping, potable, and fire flow) based on the proposed land use. These new water distribution lines would connect to existing facilities that are located within the Project area and within adjacent roadways.
Pursuant to §10910 of the California Water Code (SB 610) and information provided in the Project's WSA, BCVWD has determined that currently available and planned supplies are sufficient to meet the water demands of the proposed Project in addition to the existing and other planned project demands during normal, single dry and multiple dry years over the next 20 years. Pursuant to the California Government Code Section 66473.7, (SB 221) BCVWD has determined that it has sufficient and adequate water supply available to serve the long-term needs of the Project in addition to the existing and other planned project demands during normal, single dry and multiple dry years over the next 20 years. Refer to Attachment A for more details regarding water supply and services.
The Developer would be responsible for deposits related to construction inspection, plan review, and coordination to the BCVWD. The Developer would be required to coordinate directly with the BCVWD regarding any water system improvements or service connections. Additionally, the Developer would pay fees pursuant to the incumbent City of Beaumont Fee Schedule to cover the City's cost to fund plan review, coordination, and inspection of proposed water distribution systems improvements.
Development proposals within the Project site would be responsible for capital costs of on -site water systems, costs to connect to area off -site water distribution systems; and on -going water service fees. In combination, these funding sources finance areawide water system improvement plans, operations, and maintenance. Users would directly pay for the cost of services provided. Any increased water service demands resulting from anticipated development within the Project site would have little or no net effect on the BCVWD's Annual Budget.
Other Utilities
In addition to public service providers under the jurisdiction of LAFCO, other utility purveyors provide service to the Project site. Southern California Edison would provide electric power to the Project site. The Southern California Gas Company would provide natural gas service to the Project site. Several companies provide telecommunication services, including fiber optic and broadband internet, to residences and businesses Beaumont Pointe Specific Plan
Plan of Services
throughout the City. Currently, the two largest providers in the City include Frontier Communications and Spectrum (Charter Communications).
A. Implications for Other Utilities
Construction of the Project would require connections to existing electricity, natural gas, and telecommunication facilities 350 feet east of the Project site in 4th Street in the existing right of way. The Project would be served in accordance with the State of California's Public Utilities Commission (CPUC) and Federal Energy Regulatory Commission tariffs. The utility purveyors noted above, and others not specifically identified, would be responsible for providing services to the Project site whether or not the Project site is annexed into the City. Therefore, the annexation would not affect their ability to provide services. The annexation would have no impact in this regard.
Conclusion
If the Project is annexed to the City of Beaumont, as proposed, changes in service providers will be minimal and levels of service for the Project site will be greatly improved. Water services would be provided by the BCVWD. Fire, Stormwater Drainage and Solid Waste Collection will continue to be provided by current service providers. The commercial and industrial uses planned for the Project site are not typically sources of demands for library services, parks and recreational services, or animal control services. The level of service demand for the Project raises overall call volume for fire and police protection services but is not anticipated to impact the existing fire stations or BPD's existing resources to a point that they cannot meet the demand. Adequate water supply exists, or is planned, for the Project to 2040 and beyond; and BCVWD can meet the Project needs as well as BCVWD's existing demands and the demands of the other planned developments within BCVWD's service area. Additionally, the Applicant would pay fees pursuant to the City of Beaumont Fee Schedule to fund plan review, coordination, and inspection of proposed traffic/transportation improvements, stormwater management systems, wastewater collection facilities, and water distribution systems improvements.

1 Introduction
1.1 Project Background
The Beaumont Pointe Development (previously referred to as the Jack Rabbit Trail Development and herein referred to as Project), located in the City of Beaumont, CA, will be a new 539.90 -acre industrial, commercial, and recreational complex. The project will be developed by the Beaumont Pointe Partners, LLC (Applicant). The site is currently an undisturbed hill side with the new Hidden Canyon (HC) Development to the east and the CA -60 freeway to the North. The project will be constructed over three separate phases consisting of general commercial/retail land uses and five large industrial warehouse buildings totaling approximately 5.0 million square feet of floor space.
The Project is currently located outside of the Beaumont Cherry Valley Water District's ("District") service area but within the District's sphere of influence, requiring the Project to be annexed into the District's service area. The Project's total annexation area will be 539.90 acres. As part of the annexation process, the Project will be required to obtain a District reviewed and approved Water Supply Assessment (WSA) and Plan of Service to verify that the District will have adequate water supplies for the project as well as an approved method of service.
From 2018 through 2021, the Project worked with the District to complete a Water Supply Assessment (WSA), dated April 13, 2021. The Beaumont Pointe Development WSA was originally based on the District's 2015 Urban Water Management Plan (UWMP). During the District's June 91", 2021 Board Meeting, the 2021 Beaumont Pointe WSA was presented and approved by the District's Board of Directors.
Subsequently, the District provided the Project with a conditional Will Serve Letter, which stipulated that the District will provide water service to the Project.
In August 26, 2021, four months after approval of the Beaumont Pointe WSA, the District Board of Directors approved the 2020 BCVWD UWMP, updating the District's 2015 UWMP to be in compliance with State law.
State law indicates that the WSA for a project shall utilize the most recent UWMP (See Water Code Section 10910 (c)3), which states that if the projected water demand associated with the proposed project was accounted for in the most recently adopted urban water management plan, the public water system may incorporate the requested information from that plan in preparing the WSA. In January 2022, the Project started to work with the District to provide an addendum for the purposes of identifying, summarizing, and providing modified and/or replacement language to the Project's previously approved WSA for the differences between the BCVWD 2015 and 2020 UWMP's. In August of 2022, the District approved the Beaumont Pointe WSA Addendum and the Project is currently requesting an extension to the current will serve letter.
The purposes of this report is to identify the proposed modifications to the District's distribution system to supply the Project with potable and non -potable water. The modifications will need to be designed per the District's requirements and the Applicant shall be responsible for any capital costs to tie into and construct the proposed modifications. The Project's domestic potable water (PW) and fire flow demands are proposed to be serviced from the District's 2650 pressure zone (PZ), which currently serves the westerly edge of the District's service area, south of Interstate 10 and west of Cherry Valley Blvd. As part of on- going water conservation efforts, the Project's outdoor irrigation demands are proposed to utilize non - potable water (NPW) distributed by BCVWD.
1.2 Report Objectives
The objectives of the Beaumont Pointe Development, Plan of Service Report is to identify the proposed PW and NPW infrastructure needed to service the Project's demands. Specifically, this includes the following:
• Summarize the Project's PW and NPW demands as defined in the Project's WSA (and subsequent Addendum).

2.2 Project Potable and Non -Potable Water Demands
As summarized in the Project's WSA and subsequent Addendum (see Appendix B and C), the estimated water demand for the Project is based on recent dialogue with District and the City of Beaumont staff.
Typical commercial retail and entertainment ADD factors range from 1,400 GPD/acre (City of Lathrop, CA) to 2,000 GPD/acre (City of Oxnard, CA). For conservative purposes, the WSA utilized a water demand factor of 1,500 GPD/acre. Planning Area 2 will consist of a 125 room hotel which usually exhibit much higher unit water demands and were assumed in the WSA with a single occupant estimated at 100 GPD per room.
For Planning Areas 3 through 8, BCVWD recently reviewed the total water use for a nearby industrial distribution center east of the Project site (Wolverine), and determined that the maximum water use for "big - box" warehouse distribution developments should be estimated using an employee density factor of one employee per 1,500 sf of warehouse/office space and 15 GPD per employee. This is supported by recent studies prepared by NAIOP as described in the Hidden Canyon Water Supply Assessment.
Based on conversations with the District, future developments within their service area will be required to utilize non -potable water for all outdoor irrigation demands. This is part of the District's ongoing water conservation efforts. Therefore Table 2-2 below summarizes the average day potable (indoor) and non - potable water (outdoor) demands which equates to 99,535 GPD (69 GPM) and 76,049 GPD (53 GPM) respectively.
The District's 2016 Master Plan analyzed the historical potable water demands of the District and determined that a 1.87 maximum day demand (MDD) to average day demand ratio existed from 2005 to 2014. The District's 1.87 MDD peaking factor is fairly consistent with neighboring District's MDD peaking factors such as EMWD (2.0-2.5) and the Yucaipa Valley Water District (2.0). In conclusion, the 2016 Master Plan recommended future projects within the District's service area utilize a MDD peaking factor of 2.0 for potable water planning purposes.
Based on the District's required MDD peaking factor of 2, the Project's MDD for domestic indoor potable water is equal to 199,070 GPD or 138 GPM.

2.3 Project Fire Flow Requirements
The Beaumont Pointe Development's fire flow requirements will be dictated by the Riverside County Fire Department as the development will fall under their service area. The largest fire flow requirement of the Beaumont development will be the warehouse/office buildings (industrial). California Fire Code (2019) will require each warehouse/office building to be installed with automatic sprinklers (where greater than 3,600 square feet) and have an available fire flow of 4,000 GPM for a 4 -hour window. Additionally, the District's Master Plan requires a minimum system -wide pressure of 40 psi under MDD plus fire flows conditions, with a 20 psi residual at the flowing hydrant (Table 6-3 in the District's Master Plan).

3.1 Overview of BCVWD System
The Beaumont -Cherry Valley Water District provides potable and non -potable water service to about 19,215 active accounts, (19,659 connections), as of September 2020, in the City of Beaumont and the unincorporated community of Cherry Valley in Riverside and San Bernardino Counties in Southern California. The District is located approximately 75 miles east of Los Angeles along Interstate 10 with its present service area covering approximately 28 square miles. The District's sphere of influence or ultimate service planning area, encompasses an area of approximately 37.52 square miles which will include the Beaumont Pointe Development.
3.2 Overview of the BCVWD Potable and Non -Potable Supply BCVWD owns and operates both a potable and a non -potable water distribution system. BCVWD provides potable water and scheduled irrigation water to users through the potable water system. BCVWD provides non -potable water for landscape irrigation of parks, playgrounds, school yards, street medians and common areas through its non -potable (recycled) water system.
Table 3-1 presents the BCVWD potable and non -potable water connections and demands as listed in the BCVWD 2020 UWMP.

3.3 Existing Potable Water Infrastructure Near Annexation Area — 2650 Pressure Zone The District's potable water distribution system is comprised of 11 pressure zones ranging in elevation from 2,100 feet mean sea level (MSL) to 2,900 feet. The extracted groundwater from the wells is pumped directly into the distribution system and stored in 14 different storage tanks providing a total storage volume of 22 million gallons (MG). The storage tanks are installed to provide elevated storage to maintain each pressure in each zone. The BCVWD's potable system is also constructed such that any higher zone reservoir can supply water on an emergency basis to any lower zone through a series of pressure reducing valve stations.
The District's PW system is provided with 14 storage tanks ranging in size from 0.5 to 5 million gallons (MG) providing a total storage volume of 22 MG. Please see Appendix A for a hydraulic profile of the District's PW distribution system.
The District's 2650 PZ, which currently serves the westerly part of the District's service area, is being proposed to service the Beaumont Pointe Development. The 2650 PZ, as well as the 2520 and 2370 PZ, are currently pressurized by the 5 -million gallon (MG) Hannon Tank, which is primarily filled with groundwater extracted from Well 29. Under normal operating conditions, potable water demands will be provided from the 5 MG Hannon Tank out to the 2650 PZ and the lower 2520 and 2370 PZ. The 2650 PZ is also equipped with the two pressure regulating valve stations located along Hannon Road in the north, and along 4'h Street in the south of the PZ near the Beaumont Pointe Development. The purpose of these 11
Beaumont Pointe Development
Plan of Service —Rev 2
May 2023
#6740
pressure regulating stations is allow for the higher 2750 PZ to back feed the 2650 PZ during emergency situation such as maximum day demands or fire events.
As shown in Figure 3-1, the 2650 PZ has a series of large transmission lines feeding the individual sub areas of the PZ. The District recently constructed a 24 -inch transmission pipeline that extends the service area of the 2650 PZ from north of the CA -60, south to the intersection of Potrero Blvd and 4th Street adjacent to the proposed Hidden Canyon Development
3.3.1 Potable Water Point of Connection — Hidden Canyon Development The Project is proposing to connect to the District's 2650 PZ through the adjacent Hidden Canyon (HC) Development located to the east of the project at the intersection of Potrero Blvd and 4th Street. The HC Development is scheduled to be completed before the start of the Beaumont Pointe Development.
According to the Hidden Canyon Beaumont Distribution Center — Water Demands and Domestic Water Service Calculations — January 23, 2020 (Appendix D), the design of the HC's potable water system was to address the District's concerns over water quality and water turnover in this area of the 2650 PZ. Both the HC Development (and the Beaumont Pointe Development) will require large diameter distribution lines to meet emergency fire flow conditions, however the low potable water demand during normal conditions will result in large volumes of unused water located at the end of the District's service area.
To address the District's concerns, the HC Development will install two 16 -inch lines connecting off the 24 - inch transmission line at Potrero and 4th Steet to form a distribution loop through the HC Development. The improvements will also require an isolation valve to be installed on the 24 -inch transmission line to divert flow through the Development as part of the normal conveyance path. The required length of the dual piping system through the HC will depend on the average turnover rate by the daily HC water demands.
As shown in the Appendix D, the 18 -inch distribution loop with extend up to approximately 800 LF from the western edge of the HC Development as the average HC Development PW demand will be capable of turning over this remaining segment of straight pipe within 8 hours. The District intends for the "North" 16 - inch line to be the primary potable water service for the HC Development from the 2650 PZ Hannon Tank and the "South" 16 -inch line to be a redundant service from the 4th Street 2750/2650 pressure reducing station.
This service concept allows the District to provide redundant daily and emergency service, eliminate large diameter dead end pipes, and allow for the 2750 PZ to flush out the distribution pipelines and back feed the 5 MG Hannon Tank due to the relatively low average day demand. 12

3.4 Proposed Potable Water Improvements
The proposed potable water improvements will be designed to provide redundant daily and emergency service while reducing the potential water quality and turn -over concerns associated with the Project's low potable water demand. All proposed potable water improvements shall be constructed by the Applicant (per the District's requirements and standards) and will be owned and operated by the District upon project completion.
To address the development's high fire flow requirements, as shown in Figure 3-2 & Figure 3-3, the existing 16 -inch distribution loop from the HC Development will be extended to service the Project. To reduce potential water quality issues, the following improvements will be provided. • A single 8 -inch line will connect to the 16 -inch loop to service Project's domestic (non -fire flow) potable water demands. The single 8 -inch line will be routed along 4th Street terminating between Planning Areas 7 and 8. A single 8 -inch line was selected as it is the smallest size allowed within the District's distribution system, and with the Project's ADD of 99,535 GPD, the Project will be able to provide a sufficient turn -over rate of 5.2 hours. While a loop helps redundancy and hydraulic stability in a distribution system, because of the Project's location at the end of the District's service area, the added piping would only increase water quality issues due to low demand. • Similar to the HC Development, extending the 16 -inch distribution loop and diverting the primary flow path through the HC development will allow District to flush out and back feed the 2650 PZ from the 4th Street 2750/2650 pressure regulating station. A 16 -inch isolation valve will be installed within the HC Development to divert the primary flow path west. The existing 24 -inch isolation valve at Potrero Blvd will remained closed.
• To be discussed further below, four District approved, 10 -inch reduced pressure backflow preventers (RPZ) in a 2 duty + 1 standby configuration will be installed on the fire flow distribution piping feeding the Project's fire service distribution loop. Because of the length of piping needed for the Development, diverting the all PW through the Project will increase water quality concerns (due to low demands) and will limit the ability of the District to flush out area due to the large amount of water required.
The Project's fire flows will be provided through a 12 -inch northern and 16 -inch southern fire flow distribution loop. The south 16 -inch line is designed as the primary service will all of the building fire service laterals connecting to the 16 -inch line. The northern 12 -inch will provide hydraulic stability/redundancy but will also allow for fire hydrants to be installed along the northern edge of the property. Please note that the 800 LF of 18 -inch pipe installed on the south loop will be re -purposed as part of the improvements. Any additional requirements from the Riverside County Fire Department will be incorporated into the project's design documents accordingly.

3.4.1 Development Stages
As described in Section 2.1, the Project will be constructed over 3 separate phases with Planning Areas 1-4, 5-6, and 7-8 constructed in Phase 1, 2, and 3 respectively. As shown in Figure 3-3, the design concept of a looped fire distribution loop and a single 8 -inch potable water line capable of being turned over by the connected planning areas will be continued throughout the Development phases. A key part of the design is the construction of the 12 -inch line connecting the northern and southern fire flow lines between planning areas 4 and 5 which will provide a loop during the interim conditions.
3.4.2 Design Specifications
All proposed potable water improvements will be designed and constructed per the requirements and standard details of the District. This specifically includes the following parameters referenced in the District's 2016 Potable Water Master Plan. All District preferred equipment manufacturers will be listed in the bid specifications to help provide commonality for future maintenance and spare parts.

3.4.3 Modeling of Proposed Potable Water Improvements — Modeling Assumptions Bentley's WaterGEMS for AutoCAD 2019 water distribution analysis and design software was used to conduct a steady state analysis of the proposed potable water improvements for the Beaumont Pointe Development under MDD plus fire flows conditions. A steady-state analysis determines the operating behavior of the system at a specific point in time under steady-state conditions (i.e. demands and hydraulic grades remain constant over the analyzed period).
The Beaumont WaterGEMS model was created from a combination of preliminary grading files of the development, ArcGIS aerial imaging, and potable water utility exhibits included in the District's Master Plan (see Appendix E). The following baseline assumptions were used in the steady-state analysis, with several components taken from the District's requirements.
• All pipes were assigned a Hazen -Williams friction loss coefficient of 130. • The location of PW demands were assigned at the nearest applicable junction. • The location of all existing PW transmission lines were assumed to match the District's PW utility exhibits. Only transmission lines were included in the model o The elevation of all lines were assumed to be installed with 4 feet of cover (4 feet below the finished grade). Finished grade elevations were provided by Google Earth. • The model only includes the MDDs of the Beaumont Pointe Development. • The model assumes the 5 -MG Hannon Tank is the primary source of pressure for the 2650 PZ. • The 5 -MG Hannon Tank was assumed to half full with a water level elevation of 2,662.35 feet. • The boundaries of the PZ were assumed to match the District's PW utility exhibits. • 4th Street Pressure Regulating Station
o As stated in the Design of the 4th Street 2750/2650 PRV station TM (see Appendix E) the station was modeled under its worse supply conditions of 70 psi at the station and with a flow restrict of 6,000 GPM.
■ Since the station will be installed at the existing grade (approximately 2,450 feet), the 2750 PZ was modeled as an elevated reservoir with a HGL of 2,611.7 feet (70 psi) simulating the lowest supply pressure from the 2750 PZ • Recommended Backflow Preventers on Fire System Distribution Loop o To model the backflow preventers on the Development's fire system, the District's Standard Plate 7, and Zurn's reduced pressure detector backflow preventer model 475DA were inputted as general purpose valves. This allowed for the manufacturer's head loss curves to be inputted into the model under different operating conditions.
Fire Flow Analysis
WaterGEMS has a fire flow analysis feature which determines the available fire flows at each junction under steady-state conditions. The available fire flows at a single junction are determined after the system wide MDDs have been satisfied and as long as specific, user -defined, operating criteria are satisfied. In other words, the fire flow analysis determines the available fire flows for a single fire event if it were to occur at each of the selected junctions.
As required by Section 6 of the 2016 Master Plan the following operating constraints/requirements were inputted into the fire flow analysis.
• The calculated available fire flows must also be provided in conjunction with MDDs. • A minimum residual pressure at each junction tested for available fire flows must be greater than or equal to 20 psi as fire flows are being extracted.
• A minimum zone wide pressure at each junction must be greater than or equal to 40 psi during the fire flow analysis.
• The fire flow analysis shall simulate one 5,000 GPM fire flow event at each of the tested junctions.
If 5,000 GPM cannot be provided the model will determine the next available fire flows while meeting the user defined performance criteria.
18
Beaumont Pointe Development
Plan of Service —Rev 2
May 2023
#6740
o For the purposes of analyzing the performance of the distribution system, the upper limit of the fire flow analysis was set at 5,000 GPM, even though the highest fire flow requirement is 4,000 GPM.
• The maximum velocity in any pipe shall not exceed 10 feet per second.
3.4.4 Modeling of Proposed Potable Water Improvements — Modeling Results Figure 3-4 shows the available fire flows at each junction under MDD plus fire flow conditions. Each junction was capable of providing the required fire flows of the specified location's land use. For example, the tested junctions within the industrial land uses in the Project were able to provide a fire flow greater than 4,000 GPM.
Figure 3-5 shows the residual pressure during a simulated fire event at each specified junction while maintaining the performance requirements stated in Section 3.4.3 within the distribution system. In other words if the specified junction was able to obtain a fire flow of 4,000 GPM as shown in Figure 3-4, then Figure 3-5 shows the residual pressure available at the junction if 4,000 GPM was flowing through the junction. Please note that the fire flow analysis is capped out at 5,000 GPM.
Importance of the 4th Street 2750/2650 Pressure Regulating Station Figure 3-6 below shows the performance of the distribution model if the 4th street 2750/2650 pressure regulating station was taken out of service. As shown there is a notice drop in the available fire flows within the Project with areas along the southern distribution line close to or below the required 4,000 GPM fire flow requirement. It is recommended that should the 4th Street station be taken out of service, the District leave the 24 -inch isolation valve open (instead of normally closed to diverting water through the Hidden Canyon Development) as this will allow for the 5 MG Hannon Tank to utilize both 16 -inch lines to reliability feed the areas fire flows.

3.5 Existing Non -Potable Water Infrastructure Near Annexation Area As of 2018, BCVWD has over 44 miles of non -potable water transmission and distribution system in place.
The backbone transmission system forms a loop around the City of Beaumont and is comprised of primarily 24 -in diameter cement mortar lined, ductile iron pipe, all installed after year 2000. The system includes a 2 -MG reservoir and three major non -potable water PZ (2800, 2600 and 2520 PZ).
The 2800 NPW PZ is currently separated from the 2600 and lower PZ. The 2800 NPW PZ is supplied with non -potable groundwater from Well 26 and supplemented with PW via air -gap at the 2800 Zone 2 -MG NPW reservoir. The 2600 and lower non -potable water pressure zones are supplied with potable water through air -gapped interconnections between the potable and non -potable water system. The adjacent Hidden Canyon Development will extend the 18 -inch NPW main from 4th Street and Potrero Blvd to the edge of the BPD.
3.6 Proposed Non -Potable Water Infrastructure
All proposed non -potable water improvements shall be constructed by the Applicant (per the District's requirements and standards) and will be owned and operated by the District upon project completion.
In order to minimize the use of potable water, the Development's landscaping design shall conform to the City of Beaumont Landscaping Ordinances and utilize NPW for irrigation demands. The existing 18 -inch NPW line from Hidden Canyon will be reduced to 14 -inches and extended along 4th Street within the development. All NPW lines shall be designed and installed in accordance with the City and BCVWD requirements. Lines shall be constructed of ductile iron pipe with push -on joints (with appropriate restraints), and bagged with purple polyethylene bags as required by either the District or the DDW. Signs shall be posted around all use areas stating that non -potable water is being used and it is unsafe to drink.
All signage shall be installed in accordance with the DDW requirements. The irrigation services connections shall be made with proper reduced -pressure (RP) devices. 23

3.7 Required Engineering
The Applicant shall perform all necessary calculations, and prepare construction drawings fully describing the work required, including main line extension, fire service assemblies and connection to the existing pipelines for service. The construction drawings, calculations, and other works, shall be prepared by, or under the direct supervision of a Civil Engineer registered in the State of California. All design work shall conform to District's Standards and be subject to the approval of the District.
3.8 Required Water Services
Final domestic and non -potable meter sizes will be determined by the Applicant, but shall include backflow devices (where necessary), angle meter stop, and appropriate fittings in accordance with District's standard drawings and specifications.
3.9 Required Fire Hydrants
The Applicant shall install the necessary fire hydrants and appurtenances subsequent to the determination of fire flow requirements by the County of Riverside. The District typically requires wet -barrel type fire hydrants with one 4 -inch and two 2-1/2 inch outlets, in accordance with AWWA. Fire hydrants shall be located generally behind curbs or sidewalks, if sidewalks are adjacent to curb, the Applicant shall refer to the District's specifications and standards for the appropriate location of off -site hydrant(s). Where on -site private fire hydrants are located in parking areas, bollards shall be installed (minimum of 4) around fire hydrant heads in accordance with the Riverside County Fire Department standards or City of Beaumont Standards as applicable. The jurisdictional Fire Department shall approve all fire hydrant locations.
3.10 Main Line Extension Agreement
As a result of additional mainline pipe facilities to be owned and operated by the District, the Applicant shall execute a mainline extension agreement with the District. All applicable reimbursements (if any) shall be in accordance with the District's adopted policies and procedures.
3.11 Required Fees
The Applicant shall pay all applicable deposits, District charges, front footage fees, facility and fees (capacity charges) prior to construction of any off -site water system improvements. Monthly service charges will be in accordance with the applicable District Rules and Regulations.
Other feeds include meter installation fees, which are paid by the Developer at time of construction for a project. Deposits are collected to cover District costs for plan check, GIS and record drawing data, and construction inspection. The Developer posts a performance, labor and material bond for the construction and a maintenance bond once construction is completed and approved by the District
3.12 Financing of the Proposed Improvements — Community Facilities District The costs associated with the engineering, construction and permitting of all the proposed potable water improvements shall be paid by the Applicant.
Based on the Project's location at the perimeter of the District's sphere of influence, the proposed improvements to the District's distribution systems will only be servicing the Project's low domestic potable water demands. This would place a financial burden on the District's existing rate payers to fund the operation, maintenance and eventual replacement of the improvements over the life of the Project if an alternative funding mechanism was not established.
As a result, the Applicant and District shall enter into a Service Agreement pursuant to which the Applicant will agree that the District shall form a community facilities district (CFD) that will include only the Project 25

land and that will impose an annual special tax on the land to finance 100% of costs of the O&M and replacement of the proposed improvements.
3.12.1 Financing Model
Total Annual Special Taxes of Community Facilities District As shown in Appendix G, the CFD administrator will be responsible for calculating each year's levy of special taxes and providing the County Assessor with the amounts to include in the property tax bills for the Project land. The special taxes collected annually for replacement will be deposited into a discrete account to be maintained by the District for the purpose of funding the future replacement costs of the proposed PW and NPW improvements and the special taxes collected for O&M and CFD administrative expenses would be deposited in the District General Fund or a subaccount as described below:
•
Infrastructure Replacement Funds
o The PW and NPW distribution systems will consist primarily of distribution piping and infrastructure such as valves. Both the PW and NPW systems will utilize cement mortar -lined ductile iron pipe of various sizes and distribution infrastructure such as butterfly valves, hydrants, meter assemblies and air related valves. o The annual deposit into the replacement account will be based on the costs associated with replacing the completed portions of the PW and NPW distribution system at the end of their respective service life based on 2022 replacement costs and an average inflation rate of 3%.
o The estimated 2020 bid costs for the proposed PW and NPW distribution valves and piping is estimated to be $1,911,388 and $8,350,075 which includes prevailing wages for all associated labor.
For example, the estimated 2022 bid costs for the first phase of the PW and NPW distribution valves and distribution systems will be $1,005,144 and $4,646,190, respectively. Therefore, based on the average service life of 20 years for the distribution valves and 50 years for the distribution system, the first infrastructure replacement fund deposit would be $67,561 and $180,576, respectively and would increase 3% every year. When the entire PW and NPW distribution valve and distribution system is completed in year 5, the annual replacement amount deposit would be $136,792 and $369,776, respectively, increasing at 3% per year. • Operation and Maintenance Funds
An additional amount equal to 10% of the amount of the levy for replacement will also be included in the annual levy of special taxes to fund the District's costs of operating and maintaining the PW and NPW distribution system with any excess available to fund, in the District's sole discretion, any other District operations or capital facilities costs. • CFD Administrative Expenses
The annual levy of special taxes will also include an amount to cover all actual costs of administering the CFD.

1. INTRODUCTION
The Beaumont Pointe development project (BP or "Project") (formerly known as and referred to in some exhibits herein as "Jack Rabbit Trail") is proposed to be constructed in the City of Beaumont, CA on a site with gross area of approximately 540 acres south of Highway 60 and northwest of the proposed Hidden Canyon Industrial site. Project development limits will result in a graded net area of approximately 276.4 net acres. The project will consist of (1) general commercial/retail land uses on approximately 30.2 acres, and (2) five large graded building pads with one building on each pad totaling approximately 5.0 million square feet of warehouse/office structures. Existing 4th Street is proposed to be extended from the proposed alignment in Hidden Canyon to the BP site. The Riverside County Fire Department has identified a fire flow requirement for the Project of 4,000 gpm for 4 hours. The Project site will be annexed into the Beaumont Cherry Valley Water District (BCVWD) service area.
The Project site was previously planned with a land use density of 2,000 equivalent dwelling units (EDUs) and was included in the BCVWD's 2015 Urban Water Management Plan (UWMP) with 2,000 EDUs (previously identified as Jack Rabbit Trail). Based on the District's adopted EDU usage factor of 0.546 AFY/EDU, this equates to an estimated water demand of 1,092 AFY. The new BP land use plan estimates a density of 360 EDUs, representing a reduced site density by 82 percent. The water demand estimate using specific factors developed for each of the land uses currently proposed for BP, provides an updated demand estimate of 197 AFY. As a result of the changed land use plan, the Water Supply Assessment (WSA) accounts for a vastly reduced water demand estimate from what the UWMP assumes for the site.
2. WATER SUPPLY ASSESSMENT (WSA) LEGISLATIVE REQUIREMENTS Two Senate Bills passed in 2001 to advance water supply planning efforts in California and provide for developing comprehensive water policies to meet future water needs by integrating water supply and land use planning. These were Senate Bill 221 and Senate Bill 610, (SB 221 and SB 610, respectively). The intent was to provide additional assurance that new projects, as defined by the legislation, will have reliable water supply both now and 20 years into the future considering existing and other new development projects also under consideration. The legislation provides for evaluation of those common water sources in order to confirm their ability to continue supplying existing water users while concurrent projects come on line, as well as keep decisionmakers adequately informed of the proposed projects, and all concurrent development projects' water demands as a measure against current water supply entitlements.
2.1 Senate Bill 221 (SB 221)
SB 221 applies to residential subdivisions and chaptered in Government Code §65867.5 et seq which states:
(c) A development agreement that includes a subdivision, as defined in Government Code §666473.7, shall not be approved unless the agreement provides that any tentative map prepared for the subdivision will comply with the provisions of §666473. 7.
Government Code §666473.7 states:
(a) For purposes of this section, the following definitions apply:
Beaumont Pointe
Water Supply Assessment
(1) "Subdivision" means a proposed residential development of more than 500 dwelling units, except that for a public water agency that has fewer than 5,000 service connections, "subdivision" means any proposed residential development that would account for an increase of 10 percent or more in the number of the public water system's existing service connections.
(b)(1) The legislative body of a city or county or the advisory agency, to the extent that it is authorized by local ordinance to approve, conditionally approve, or disapprove the tentative map, shall include as a condition in any tentative map that includes a subdivision, a requirement that a sufficient water supply shall be available. Proof of the availability of a sufficient water supply shall be requested by the subdivision applicant or local agency, and shall be based on written verification from the applicable water supply system within 90 days of a request. (1) Government Code §666473.7 shall not apply to any residential project proposed for a site that is within an urbanized area and has previously been developed for urban uses, or where the immediate contiguous properties surrounding the residential project site area, or previously have been, developed for urban uses, or housing projects that are exclusively for very low and low-income households.
(a)(2) "Sufficient water supply" means the total water supplies available during normal, single -dry and multiple -dry years within a 20 -year projection that will meet the projected demand associated with the proposed subdivision, in addition to existing and planned future uses, including but not limited to agricultural and industrial uses.
This does not mean that 100 percent of the development's unrestricted water demand must be met 100 percent of the time, nor does it mean the new development may not have an impact on the service level of existing customers. A "sufficient water supply" may be found to exist for a proposed subdivision and for existing customers, even where a drought -induced shortage will be known to occur, as long as a minimum water supply can be estimated and planned for during a record drought.
2.2 Senate Bill 610 (SB 610)
SB 610, chaptered in Water Code §10910 et seq, requires a city or county that determines a "Project," as defined in Water Code §10912, is subject to the California Environmental Quality Act (CEQA), the city or county must identify any public water system that may supply water for the project and to request those public water systems to prepare a specified water supply assessment (WSA), except as otherwise specified. Water Code §10912 defines a "Project" as any of the following:
(1) A proposed residential development of more than 500 dwelling units. (2) A proposed shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet (sf) of floor space. (3) A proposed commercial office building employing more than 1,000 persons or having more than 250,000 sq. ft. of floor space.
(4) A proposed hotel or motel, or both having more than 500 rooms.
Beaumont Pointe
Water Supply Assessment
(5) A proposed industrial, manufacturing, or processing plant, or industrial park planned to house more than 1,000 persons, occupying more than 40 acres of land, or having more than 650,000 sq. ft. of floor area.
(6) A mixed -use project that includes one or more of the projects specified in this subdivision. (7) A project that would demand an amount of water equivalent to, or greater than, the amount of water required by a 500 -dwelling unit project.' The basic question to be answered in the WSA is:
Will the water supplier's total projected water supplies during normal, dry, and multiple dry years during a 20 -year projection meet the projected water demand of the proposed project, in addition the water supplier's existing and planned future uses, including agricultural and manufacturing uses?
The WSA, under SB 610, is to include the following, if applicable to the supply conditions:
1. Discussion regarding whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20 - year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses.
2. Identification of existing water supply entitlements, water rights, or water service contracts secured by the purveying agency and water received in prior years pursuant to those entitlements, rights, and contracts.
3. Description of the quantities of water received in prior years by the public water system under the existing water supply entitlements, water rights or water service contracts.
4. Water supply entitlements, water rights or water service contracts shall be demonstrated by supporting documentation such as the following:
a. Written contracts or other proof of entitlement to an identified water supply. b. Copies of capital outlay program for financing the delivery of a water supply that has been adopted by the public water system.
c. Federal, state, and local permits for construction of necessary infrastructure associated with delivering the water supply.
d. Any necessary regulatory approvals that are required to be able to convey or deliver the water supply.
5. Identification of other public water systems or water service contract holders that receive a water supply or have existing water supply entitlements, water rights, or water service contracts, to the same source of water as the public watersystem.
6. If groundwater is included for the supply of a proposed project, the following additional information is required:
a. Description of groundwater basin(s) from which the proposed project will be supplied. Adjudicated basins must have a copy of the court order or decree adopted and a description of the amount of groundwater the public water system 1 The water use for one dwelling unit depends on regional climate and varies from agency to agency
Beaumont Pointe
Water Supply Assessment
has the legal right to pump. For non -adjudicated basins, information on whether the California Department of Water Resources has identified the basin as overdrafted or has projected that the basin will become overdrafted if present management conditions continue, in the most current bulletin of the Department of Water Resources that characterizes the condition of the basin, and a detailed description of the efforts being undertaken in the basin to eliminate the long-term overdraft.
b. Description and analysis of the amount and location of groundwater pumped by the public water system for the past five (5) years from any groundwater basin from which the proposed project will be supplied. Analysis should be based on information that is reasonably available, including, but not limited to, historic use records.
c. Description and analysis of the amount and location of groundwater projected to be pumped by the public water system from any groundwater basin from which the proposed project will be supplied. Analysis should be based on information that is reasonably available, including, but not limited to, historic use records.
d. Analysis of sufficiency of the groundwater from the basin(s) from which the proposed project will be supplied.
7. The water supply assessment shall be included in any environmental document prepared for the project.
SB 610 prescribes a timeframe within which a public water system is required to submit the assessment to the city or county and authorizes the city or county to seek a writ of mandamus to compel the public water system to comply with requirements relating to the submission of the assessment.
SB 610 requires the public water system, or the city or county, as applicable, if that entity concludes that water supplies are, or will be, insufficient, to submit the plans for acquiring additional water supplies.
SB 610 requires the city or county to include the water supply assessment and certain other information in any environmental document prepared for the project pursuant to the act.
2.3 Summary
The Senate bills are quite similar; SB 221 applies to proposed residential subdivisions over 500 dwelling units or a subdivision project that proposes 10 percent of the number of existing agency water connections, whichever is smaller; SB 610 to other types of large projects or mixed use projects. Both require documentation of water supply and demand under normal, dry and multiple dry year scenarios to accommodate the project plus existing and known planned projects. Both rely on the agency's UWMP for support.
Based on the description in the introduction, the proposed Beaumont Pointe development project requires a water supply assessment pursuant to SB 610 under Section 10912 (a) (2). The Project includes a proposed business establishment having more than 500,000 square feet of floor space. The Project proposes over 5,000,000 square feet of floor space.
For the Project, the water purveyor is the Beaumont -Cherry Valley Water District (BCVWD).

3. URBAN WATER MANAGEMENT PLANNING ACT
3.1 Background
The California Water Code requires that all urban water suppliers within the state, serving over 3,000 acre-feet (AF) of water (1 AF = 325,829 gallons) or having at least 3,000 service connections, to prepare Urban Water Management plans (UWMPs) on a five-year, ongoing basis demonstrating their continued ability to provide water supplies for current and future expected development under normal, single dry and multiple dry year scenarios. The Urban Water Management Planning Act was enacted in 1983 and amendments were made periodically since then. The Act also requires imported water suppliers to prepare UWMPs. Water Code sections §10610 through §10656 detail the information that must be included in the plans. These plans also require the assessment of urban water conservation measures and wastewater recycling as well as a water shortage contingency plan outlining how the municipal water provider will manage water shortages of up to 50 percent of their normal supplies in a given year.
An UWMP is a planning tool that provides general guidance to water management agencies. It provides managers and the public with past and current water supply issues facing the agency.
It is not a substitute for project -specific planning documents, nor was it intended to be, when mandated by the State Legislature. When specific projects are chosen to be implemented, detailed project plans are prepared, environmental analysis (if required) is prepared, and financial and operational plans are developed.
"The UWMP is intended to function as a planning tool to guide broad -perspective decision -making" by water agency managers and directors.2 It should not be viewed as an exact blueprint for supply and demand management. Water management in California is not a matter of certainty and planning projections and may change in response to a number of factors. "[L]ong-term water planning involves expectations and not certainties. The State Supreme Court has recognized the uncertainties inherent in long-term land use and water planning and observed that the generalized information required ...in the early stages of the planning process are replaced by firm assurances of water supplies at later stages."3 It is appropriate to look at the UWMP as a general planning framework, not a specific action plan. It is an effort to generally answer a series of planning questions including:
• What are the potential sources of supply and what is the reasonable probable yield from them?
• What is the probable demand, given a reasonable set of assumptions about growth and implementation of good water management practices?
• How well do supply and demand figures match up, assuming that the various probable supplies will be pursued by the implementing agency?
Based on the answers to these questions, the implementing agency will pursue feasible and cost - 2 Sonoma County Water Coalition v. Sonoma County Water Agency (2010) 189 Cal. App. 4th 33, 39, taken from SGPWA 2015 UWMP.

effective options and opportunities to meet demands.
The UWMP Act requires the supplier to document water supplies available during normal, single dry, and multiple dry water years over a 20 -year projection and the existing and projected future water demand during the same 20 -year period. The Act requires that the projected supplies and demands be presented in 5 -year increments for the 20 -year projection period.
Like SB 221 and SB 610, specific levels of supply reliability are not mandated (i.e., whether a specific level of demand can be met over a designated frequency); rather, the law provides that it is a local policy decision of the water provider as part of the planning process. As provided for in the law, the WSA can rely on the data in the latest UWMP in assessing the water demand of the proposed project relative to the overall increase in demands expected by BCVWD. The Beaumont Pointe development project site was included in Table 3-6 of BCVWD's 2015 UWMP (previously identified as Jack Rabbit Trail). The Project site was previously planned with a land use density of, and corresponding water demand for, 2,000 equivalent dwelling units (EDUs).
The new BP land use plan estimates a significantly reduced density of 360 EDUs, representing a reduced site density by 82 percent and corresponding water demand estimate.
In late 2017 and 2018, BCVWD prepared a set of "White Papers" that evaluated the growth in demand within the SGPWA and the current and future water supply from the SGPWA on a regional basis. The White Papers determined that the rate of growth has reduced and refines the imported water supply accordingly. This is discussed later in this WSA.
3.2 San Gorgonio Pass Water Agency 2015 UWMP
The Beaumont Pointe project is located within the service area of the San Gorgonio Pass Water Agency (SGPWA or Pass Agency). BCVWD provided data to SGPWA on BCVWD's projected demands so the SGPWA could prepare their UWMP. Because the California Department of Water Resources (DWR) required the imported water suppliers to submit their UWMPs earlier than the retail agencies, BCVWD made some preliminary estimates of their demand over the 20 - year projection period and provided the projections to SGPWA. These preliminary estimates deviated slightly from the actual demands in BCVWD's 2015 UWMP. Table 3-1 is taken from SGPWA 2015 UWMP (Table 2-4):
Table 3-1 - Projected Water Demands on SGPWA (AF)

SGPWA's 2015 UWMP states the "retail purveyor demands reflect reasonably anticipated supplies through the planning periods" and take into account non-SGPWA supplies available to the retail purveyors, such as local groundwater, recycled water, etc.
Since the Beaumont Pointe project site was included in the demands in BCVWD's 2015 UWMP,
Beaumont Pointe
Water Supply Assessment
it is considered to be included in the 2015 SGPWA UWMP, adopted by SGPWA Board of Directors as Resolution No. 2017-03, on March 20, 2017. "Other" demands in Table 3-1 reflect the demand from other agencies in SGPWA service area not currently receiving imported water from SGPWA.
In the introductory section of the SGPWA's 2015 UWMP, the SGPWA reviewed the water supply and demand requirements on a regional basis and did not focus on specific conditions within the service area of the retail water agencies.
"It is the stated goal of SGPWA to import supplemental water and to protect and enhance local water supplies for use by present and future water users and to sell imported water at wholesale to local retail water purveyors within its service area. Based on conservative water supply and demand assumptions over the next 25 years in combination with conservation of non -essential demand during certain dry years, the [Urban Water Management] Plan successfully achieves this goal. It is important to note that this document has been completed to address regional resource management and does not address the particular conditions of any specific retail water agency or entity within the SGPWA service area. The retail urban water suppliers within SGPWA service area are preparing separate UWMPs, but SGPWA has coordinated with the retailers during development of this Plan to ensure a level of consistency with the retailers to the extent possible.4 BCVWD recognizes and acknowledges the disclaimer statement within the 2015 Urban Water Management Plan prepared by the SGPWA related to regional planning. While the UWMP prepared by the SGPWA "...does not address the particular conditions of any specific retail water agency..." BCVWD relies upon the policies and practices of the SGPWA as a foundation for regional water supply solutions. In other words, while the SGPWA's regional planning document does not address local water conditions, BCVWD does rely upon the policies of the SGPWA to provide comprehensive regional solutions related to the use of imported water in the Pass area.
As example of the policies and practices adopted by the SGPWA and relied upon by BCVWD include, but are not limited, to the following:
• San Gorgonio Pass Water Agency, Ordinance No. 8, An Ordinance Establishing Rules and Regulations for SGPWA Water Service, February 7, 2005; • San Gorgonio Pass Water Agency Strategic Plan, May 2012; • San Gorgonio Pass Water Agency, Resolution No. 2014-02, A Resolution of the San Gorgonio Pass Water Agency Establishing a Policy for Meeting Future Water Demands, February 18, 2014;

3.3 BCVWD's 2015 UWMP
There were some minor differences between the projections in BCVWD's 2015 UWMP and the projections provided to SGPWA for their 2015 UWMP. These differences stemmed from the need for BCVWD to provide preliminary demand projections early on so the SGPWA could meet their prescribed deadline.
BCVWD's demands for imported water are presented in BCVWD's 2015 UWMP (Table 6-26) and are repeated in Table 3-2 below. Table 3-2 shows the actual imported water demand to meet the potable water demand plus the banking water demand to ensure drought -proofing of future development. If imported water is not available in a given year, no banking will occur. But when imported water is available, any deficiencies from previous years would be "carried over" and "made up." As can be seen, there is a slight difference between the demands in Table 3-2 versus those shown above in Table 3-1.

4.2 Estimated Water Demand
The estimated water demand for the Project is based on recent dialogue with District and the City of Beaumont staff. The total Project consists of approximately 30.2 acres of general commercial land uses and 5.0 million square feet (sf) of industrial distribution warehouse.
For Planning Areas 1 and 2 typical water usage factors used in the industry can range from 1,500 to 3,000 gallons per day (gpd) per acre. Major area water agencies that have published usage factors by land use category includes East Valley Water District (2014) and Eastern Municipal Water District. These agencies have adopted usage factors for general commercial developments at 2,050 and 2,000 gpd per acre to estimate general commercial water demands.
Beaumont Pointe includes hotel uses which are typically grouped within the general commercial classification; however, usually exhibit much higher unit water demands. For the purpose of estimating water demands for the WSA, hotel uses are deemed similar to residential uses with a single occupant estimated at 100 gpd per room.
For Planning Areas 3 through 8, BCVWD recently reviewed the total water use for a nearby existing 720,000 sf industrial distribution center east of the Project site (Wolverine), and determined that the maximum water use for "big -box" warehouse distribution developments should be estimated using an employee density factor of one employee per 1,500 sf of warehouse/office space and 15 gpd per employee. This is supported by recent studies prepared by NAIOP 5 as described in the Hidden Canyon Water Supply Assessment. Therefore, because BP Planning Areas 3 through 8 development is virtually identical to the Wolverine "big -box" product this factor is appropriate for the WSA for BP. Thus, the total number of employees contributing to water demand at full buildout of Planning Areas 3 through 8 at BP is estimated to be 3,306h. These usage factors are consistent with the existing Wolverine project and completed planning studies for Hidden Canyon. Planning Areas 9 and 10 will remain open space. Tables 4-2 and 4-3 summarize the estimated BP Project indoor (potable) and outdoor (non -potable) water demands:

Table 4-2 and 4-3 calculate to a total estimated water demand at BP buildout of 175,584 gpd, or 197 AFY. Based on BCVWD equivalent dwelling unit usage of 0.546 AFY per equivalent dwelling unit, this equates to 360 EDUs. Of the total water demand, candidate non -potable water demand for outdoor irrigation is estimated to be 85.2 AFY, or approximately 43 percent of the total demands of the Project.
5. BCVWD WATER SYSTEM
BCVWD owns and operates the water system which would serve the Beaumont Pointe development project. BCVWD was first formed in April 1919, to provide domestic and irrigation water to the developing community of Beaumont and the surrounding area. BCVWD was originally named the Beaumont Irrigation District. In 1973, the name was changed to the Beaumont -Cherry Valley Water District. Sometime after that the hyphen was dropped from the name. However, even though the name has changed, the BCVWD's authority comes from the Irrigation District Law of the State of California.
BCVWD owns approximately 1,524 acres of watershed land north of Cherry Valley along the Little San Gorgonio Creek (also known as Edgar Canyon) and Noble Creek. There are two stream diversion locations within Little San Gorgonio Creek that are in the Department of Water Resources, Division of Water Rights, database. The diversions have pre -1914 recorded water rights amounting to 3,000 miners inch hours (MIN) or approximately 45,000 acre-feet per year (AFY) of right for diversion of water for domestic and irrigation uses. However, BCVWD has never had a demand that requires such large quantities of water supply; and the watersheds may not be capable of supplying such quantities during an average year. The creeks/canyons have been used for water development via diversions for irrigation and domestic service since the latter part of the 1800s. Currently, BCVWD diverts water from Little San Gorgonio Canyon Creek into a series of ponds adjacent to the creek where it percolates and recharges the shallow aquifers in the Canyon. BCVWD's wells located in Edgar Canyon provide a significant portion of BCVWD's water supply.
Figure 3 shows BCVWD's present Service Boundary and Sphere of Influence (SOI). BCVWD's present service area covers approximately 28 square miles, virtually all of which is in Riverside County and includes the City of Beaumont and the community of Cherry Valley. BCVWD-owned watershed land extends across Riverside County line into San Bernardino County where BCVWD operates a number of wells and several reservoirs.
BCVWD's SOI, or ultimate service planning area, encompasses an area of approximately 37.5 square miles (14.3 sq. mi. are in the City of Beaumont). This SOI was established by the Riverside and San Bernardino County Local Agency Formation Commissions (LAFCOs). SOIs are established as a planning tool and help establish agency boundaries and avoid problems in service, unnecessary duplication of costs, and inefficiencies associated with overlapping service.
BCVWD's SOI is bounded on the west and north by the Yucaipa Valley Water District (YVWD) and on the east by the City of Banning. The northerly boundary of Eastern Municipal Water District (EMWD) is one mile south of the BCVWD's southerly SOI boundary. The area between EMWD and the BCVWD's SOI is not within any SOI and could be annexed to either BCVWD or EMWD.
BCVWD's SOI in Little San Gorgonio Canyon follows Oak Glen Road. The area west of Oak Glen
Beaumont Pointe
Water Supply Assessment
Road is within YVWD's SOI, and the area east of Oak Glen Road is within BCVWD's SO1.
The service area ranges in elevation from 2,300 feet above mean sea level in Fairway Canyon area of Beaumont on the southwestern boundary, to 2,900 feet in Cherry Valley, and to over 4,000 feet in the upper reaches of the SOI.
The area serves primarily as a "bedroom" community for the Riverside/San Bernardino Area and the communities east of Los Angeles County along the 1-10 corridor.

5.1 Overview of BCVWD's Water System and Operation
BCVWD owns and operates both a potable and a non -potable water distribution system. BCVWD provides potable water and scheduled irrigation water to users through the potable water system.
BCVWD provides non -potable water for landscape irrigation of parks, playgrounds, school yards, street medians and common areas through its non -potable (recycled) water system.
Table 5-1 presents BCVWD 2019 potable and non -potable water connections and pumping amounts. The number of connections was 5,600 in year 2000, before the housing boom that encompassed Western Riverside County and particularly Beaumont.

5.2 Potable Water System
BCVWD's potable water system is supplied by wells in Little San Gorgonio Creek (Edgar Canyon) and the Beaumont Groundwater Basin (sometimes called the Beaumont Storage Unit or the Beaumont Management Zone). BCVWD has a total of 24 wells; 1 well is a standby. Only 20 of the wells are used to any great extent. Twelve of the wells have auxiliary engine drives, a portable generator connection, or an in -place standby generator. BCVWD has three portable generators capable of operating 50, 350 and 500 horsepower (HP) motors. The Beaumont Groundwater Basin is adjudicated and managed by the Beaumont Basin Watermaster6. BCVWD augments its groundwater supply with imported State Project Water (SPW) from the SGPWA which is recharged at BCVWD's recharge facility at the intersection of Brookside Avenue and Beaumont Avenue. Overall, the water quality from BCVWD's wells is excellent. Total Dissolved Solids (TDS) is usually below 250 mg/L. Nitrates are only a sporadic problem in a few wells at present.
BCVWD continues to monitor these wells per State Water Resources Control Board, (SWRCB) Division of Drinking Water (CDDW) requirements. No wells have had to be taken out of service because of water quality concerns.

Beaumont Pointe
Water Supply Assessment
Wells in Edgar Canyon have limited yield, particularly in dry years, and take water from shallow alluvial and bedrock aquifers; wells in the Beaumont Basin are large capacity and pump from deep aquifers — some as deep as 1,500 feet below the ground surface. The Edgar Canyon wells are very inexpensive to operate and are the preferred source; however, those wells are not able to meet the average day demand and need to be supplemented with the Beaumont Basin wells.
The Edgar Canyon wells pump to a gravity transmission main that extends the full length of the BCVWD-owned properties in Edgar Canyon. The transmission main connects to the distribution system in Cherry Valley. Water from the Edgar Canyon Wells, which is not used in the developed areas adjacent to Edgar Canyon or Cherry Valley, can be released to lower pressure zones, if needed.
During 2019, the Edgar Canyon Wells provided about 10.5 percent of BCVWD's total annual potable water supply; the rest is pumped from wells in the Beaumont Basin. BCVWD's total well capacity (Edgar Canyon and Beaumont Basin) is about 33 million gallons per day (mgd). BCVWD is easily able to meet the maximum day demand (historic maximum about 22 mgd) with the largest well out of service. Wells with auxiliary power can supply up to 21.4 mgd.
Because of the range of topographic elevations in the BCVWD's service area, 11 pressure zones are needed to provide reasonable operating pressures for customers.
BCVWD has 14 reservoirs ranging in size from 0.5 million gallons (MG) to 5 MG. Total storage is approximately 22 MG, slightly more than two (2) average days or one (1) maximum day. The reservoirs provide gravity supply to its respective pressure zones. BCVWD's system is constructed such that higher zone reservoirs can supply water on an emergency basis to lower zone reservoirs. Booster pumps in the system pump water from lower pressure zones to higher pressure zones. This provides flexibility in system operations. Sufficient reservoir redundancy exists permitting reservoirs to be taken out of service for maintenance.
The backbone transmission system in the main pressure zones is primarily 24 -inch diameter though there are some 30 -inch diameter pipelines leading to some reservoirs. The bulk of the backbone transmission and distribution pipe is ductile iron with cement mortar lining, that was installed in the last 10 to 15 years. A number of small, older, distribution lines in the system are gradually being replaced over time with minimum 8 -inch diameter ductile iron pipe. The system is capable of providing over 4,000 gpm fire flow in the industrial/commercial areas of the service area.
5.3 Imported Water and Recharge Facilities
BCVWD imported and storm water recharge facility consists of a 78 -acre site on the east side of Beaumont Avenue, between Brookside Avenue and Cherry Valley Boulevard, where imported water is currently recharged. The recharge project site was selected after extensive hydrogeologic studies and pilot testing over a multi -year period. Phase 1 of the recharge facility, located on the westerly half of the site, went on-line in late summer 2006. Phase 2 of the recharge facility was completed in 2014. To date, only imported water has been recharged at the site.
Since its operation in 2006 through the end of 2018, 84,242 acre-feet (27.4 billion gallons) of imported water have been recharged. The capacity of the recharge site is conservatively estimated at 25,000 to 30,000 AFY, based on short term studies. With more aggressive
Beaumont Pointe
Water Supply Assessment
maintenance, the capacity may be as much as 35,000 AFY.
BCVWD and Riverside County Flood and Water Conservation District (RCFWCD) are jointly in design of Beaumont MDP-Line16, a large diameter storm drain in Grand Avenue, which drains a watershed area of 505 acres to BCVWD's recharge site. This project is planned to be operational by 2022. BCVWD also envisions recharging recycled water, not needed for irrigation, at the recharge site in the future, with appropriate treatment and permits.
The SGPWA imports State Project Water (SPW) through the East Branch Extension (EBX) of the California State Water Project (Governor Edmund G. Brown California Aqueduct). EBX Phase I was completed in 2003; EBX Phase 11 was completed in 2018. The completion of EBX Phase 11 improvements brings SGPWA's imported water delivery capacity to the Pass Area to 48 cubic feet per second (cfs) or 34,750 AFY if it was operational all year continuously.
BCVWD takes water from a 20 -inch diameter turnout and metering station at the current end of the EBX at Orchard Avenue and Noble Creek in Cherry Valley. Design of an expansion of the turnout was recently completed and began the increased capacity recharge in 2019. Water from the turnout is metered by the Department of Water Resources (DWR) and then enters a 3,500 -ft long, 24 -inch diameter gravity pipeline, constructed by BCVWD, which conveys the water to BCVWD's groundwater recharge site.
The 24 -inch diameter pipeline was constructed in 2006 and at 34 cfs would have a velocity of
10.8 feet per second — a reasonable velocity for a mortar -lined pipeline. If operated eleven months out of the year at that rate, the pipeline could convey 22,500 acre-feet per year. Higher velocities could be tolerated for short periods which would result in increased short-term delivery capacity.
5.4 Non -potable (Recycled) Water System
As of 2018, BCVWD has over 44 miles of non -potable water transmission and distribution system in place. The backbone transmission system forms a loop around the City of Beaumont and is comprised of primarily 24 -in diameter cement mortar lined, ductile iron pipe, all installed after year 2000. The system includes a two (2) million -gallon recycled (non -potable) water reservoir which provides gravity storage for the system. As shown in Table 5-1, at the end of year 2019 approximately 309 connections delivered 1,547 AFY of non -potable water. The BCVWD system includes three major non -potable water pressure zones (2800 Zone, 2600 Zone and 2520 Zone) with plans to expand service to areas requiring two additional pressure zones (3040 Zone, 2370 Zone).
The 2 MG non -potable reservoir, (2800 Zone Non -potable Water Tank) constructed at the BCVWD Groundwater Recharge Site can directly receive potable water or untreated SPW through air -gap connections. The reservoir and non -potable water system can serve a blend of recycled water, imported, untreated SPW, and potable water.
The 2800 Non -potable Water Zone is currently separated from the 2600 and lower pressure zones. The 2800 Non -potable Water Zone is supplied with water from Well 26, supplemented with potable groundwater via air -gap at the 2800 Zone Non -potable water reservoir. The 2600 and lower non -potable water pressure zones can also be supplied with potable water through air -
Beaumont Pointe
Water Supply Assessment
gapped interconnections between the potable and non -potable water system. BCVWD has a capital project approved to provide fine screening to the SPW prior to entering the 2800 Zone Non -potable Water Reservoir. This project will be implemented when demands increase and/or the non -potable water system is tested and approved for recycled water use.
BCVWD is working with the City of Beaumont to secure recycled water for use in the non -potable water system. The City is currently constructing an expansion and upgrade to its existing wastewater treatment facility, which involves installing new membrane bioreactor (MBR) treatment units and additional reverse osmosis membrane treatment. Upon completion, the facility will have a capacity to deliver six (6) million gallons per day (mgd). A brine line from the treatment plant to the Inland Empire Brine Line (IEBL) in San Bernardino is also under construction. A memorandum of understanding (MOU) between BCVWD and the City for recycled water purchase and use was signed in July 2019 and the City and BCVWD are in the process of finalizing and agreement for purchase of recycled water through an ad -hoc committee of City Council members and BCVWD Board Members.
In order to have the ability to use recycled water for recharging when supply exceeds landscape irrigation demand, BCVWD plans to obtain recharge permits. Recycled water for this beneficial reuse could be supplied to BCVWD's groundwater recharge or other area facility. Recycled water use and recharge is permitted by the Adjudication.
6. UPDATED WATER DEMANDS IN SAN GORGONIO PASS AREA
In 2018, BCVWD developed a series of White Papers (White Papers No. 1 through 7) that evaluated water supply, water demands, current and future water supply costs, funding requirements and funding strategies considering both BCVWD's service area and the SGPWA as a whole. These White Papers were presented at BCVWD Board Meetings and elsewhere. The purpose of the White Papers was to assess the water supply situation vis-a-vis the growth in demand. The results of this series of White Papers indicated that the regional imported water demands in BCVWD's 2015 UWMP and the SGPWA 2015 UWMP may be overstated, primarily because of over -aggressive growth in demand, and limited consideration of recent state - mandated conservation and indoor water use requirements.
6.1 Regional Water Supply and Demand Spreadsheet Models BCVWD, in cooperation with the other major retailers, developed a Regional Water Demand Spreadsheet or Workbook which included a separate worksheet for each of the three major retailers in the SGPWA service area: BCVWD, City of Banning, and Yucaipa Valley Water District (YVWD)/City of Calimesa. The other water supply agencies, e.g., Cabazon Water District, High Valleys Water District, etc. that are not currently receiving imported water from SGPWA were also included, based on data in SGPWA's 2015 UWMP.
Beaumont Pointe
Water Supply Assessment
The spreadsheet model allows the water agency to input (and adjust):
• New EDU Water Demand, AFY/EDU
• Existing EDU Water Demand, AFY/EDU
• Infill EDUs/year
• Commercial & Institutional EDUs/yr, %Residential EDUs • Commercial & Institutional EDUs, Minimum EDUs/yr
• Water Conservation, % Reduction on Existing Demands
• Water Conservation, % Reduction on New Demands
• 2017 Year Ending Potable Water Demand, AF
• Beaumont Basin Groundwater Storage Account Maximum, AF • Beaumont Basin Groundwater Storage Account 2017 Ending Balance, AF The demand worksheets included the major development projects in each of the retailer's service areas, based on data in specific plans, water supply assessments, regional water resource planning studies, and other sources. The spreadsheets allow the water supply agencies to input their own development rates, on a year by year basis, to adjust anticipated housing startups, build - out years for large developments, and the amount of in -fill development and commercial/institution development; adjust unit water demands for new and existing housing, and account for any anticipated conservation for new and existing demands, among other items. Each water supplier could adjust their imported water banking requirements and evaluate the impact of their strategies on their own Beaumont Basin storage accounts over time.
The spreadsheet provides a graph of the agency's annual groundwater storage account balance which is automatically updated with any input change. The purpose is to allow the agencies to model, on a year by year basis, various imported water purchase and banking strategies vis-a- vis available imported water from SGPWA. Adjustments can be made to water demands using conservation factors on new and existing (older) housing units; water supply sources can include groundwater, recharged recycled water (indirect potable reuse), and captured storm water.
Beaumont Basin Watermaster's redistribution of unused overlier rights and forbearance water are included in the model.
The worksheets were reviewed by the retail water agency managers for reasonableness of growth taking into account the housing market and absorption capacity of the SGPWA service area.
These spreadsheets, and their criteria are described in detail in White Paper No. 6, and summarized below:
Separate spreadsheet models have been developed for:

Butterfield Ranch (Atwell by Pardee) was projected to start in 2015 and extend for 30 years to buildout in 2045 per the Project's Water Supply Assessment (WSA). The project recently started grading operations and currently is selling homes to be occupied in 2020. Butterfield Ranch proposes 4,862 EDUs, calculating to an average of 160 EDUs per year over the 30 -year build -out period. Rancho San Gorgonio is planned for 3,385 EDUs and was initially projected to start in 2017 and be fully built out by 2034 (17 years) per the Project's WSA (about 200 EDUs per year average over the build -out period). This project has not yet started and probably will not start until 2022 or later.
The spreadsheet for Banning included two other projects:
• Diversified Pacific (98 EDUs)
• St. Boniface (171 EDUs)
The developers have not yet published construction schedules for these. The spreadsheet assumes 2021 and 2023 for starting, and build out of 5 and 10 years, respectively, which may overestimate District demands over the next few years.
In the development of the spreadsheet model for the City of Banning, the San Gorgonio Integrated Regional Water Management Plan (SGIRWMP), May 2, 2018 (Revised August 1, 2018) was analyzed in addition to the City's 2015 UWMP. The SGIRWMP covered the SGPWA service area generally east of Highland Springs Avenue. The SGIRWMP integrated three separate studies:
• Water Supply Reliability Study
• San Gorgonio Region Recycled Water Study
• San Gorgonio Integrated Watershed and Groundwater Model Technical Memorandum
Beaumont Pointe
Water Supply Assessment
The City of Banning has firm groundwater supplies from the Banning Storage Unit, Banning Bench Storage Unit, Cabazon Storage Unit, and Banning Canyon Storage Unit totaling 9,675 AFY'
In addition, in accordance with the Adjudication, the City of Banning is entitled to 31.43% of the unused overlier pumping rights in the Beaumont Storage Unit. Watermaster developed estimates for years 2018 through 2022 and are included in the spreadsheet. The amount of unused pumping rights varies from year to year, depending on hydrologic conditions and other factors, and is evaluated by Watermaster annually. The 2018 Annual Watermaster Report indicates that Banning's reallocated unused overlier pumping amount for 2021 is 1,497 AFY, slightly more than that reported in the City's 2015 UWMP. As some of the overlying parties develop their properties, the overlier rights will be used by the potable water and recycled water supplying agency and will no longer be available for reallocation. As a result, the total amount subject to reallocation will decrease over time. BCVWD made an estimate of the unused overlier pumping rights under a "developed" or "build -out" condition and estimated the total unused overlier amount would be 1,800 AFY under full buildout. The City of Banning's share (31.43%) would be 560 AFY (rounded) at buildout. The spreadsheet allows for the gradual reduction of the unused overlier pumping rights over time. It is projected by BCVWD to decrease to 560 AFY by 2030 or so as the overlying properties develop.
The City of Banning has 52,320 AF banked in their Beaumont Basin Storage account at the end of 2018 per Watermaster. For the period 2008 through 2017, the City of Banning has recharged an average of 1,294 AFY of SPW in BCVWD's recharge facility. The City can store up to 80,000 AF.
Table 6-2 presents a summary on the Supply -Demand Spreadsheet Model for the City of Banning. The year 2040 data was projected from previous years since the model currently only extends to 2035.
Table 6-2 was based on the following criteria:
• 2017 Ending Potable Water Demand: 7,500 AFY
• New EDU water demand: 0.52 AFY/EDU
• Existing EDU water demand: 0.62 AFY/EDU
• No demand reduction due to conservation on either existing or new EDUs This was reviewed by the City of Banning. Table 6-2 indicates that the City of Banning has adequate local supply until 2035. Note that Banning's Beaumont Basin Groundwater Storage Account is full in 2030 (Per the spreadsheet model it actually fills in 2027). This indicates that the City of Banning has minimal imported water needs from SGPWA until 2040.

To develop the spreadsheet for YVWD, several references were reviewed for YVWD's water supply and projected demands within their service area lying within the SGPWA boundaries:
• 2015 SGPWA UWMP
• 2015 San Bernardino Valley Regional UWMP
• Mesa Verde Water Supply Assessment (WSA) — Draft August 11, 2017 • YVWD Strategic Plan for Sustainable Future (Adopted August 20, 2008) The EDUs for Summerwind Ranch and Mesa Verde were taken from the Specific Plans for these projects. First move -ins are scheduled to occur by 2019. Mesa Verde is estimated to start in 2022. An estimated 20 -year build -out time for Summerwind Ranch and Mesa Verde was assumed, resulting in an average of 192 and 183 EDUs per year, respectively. Per YVWD, future phases of JP Ranch will likely not start until 2025 with a 10 -year build -out period (about 50 EDUs
Beaumont Pointe
Water Supply Assessment
per year). It should be noted there will be additional EDUs associated with the developments for related commercial and retail developments, schools, parks, restaurants, etc.
Water supply sources for these projects are:
• Reallocated unused overlier pumping rights in the Beaumont Basin • Oak Valley Partners' earmarked transfer right
• Banked groundwater from storage
• Imported Water from SGPWA
• Treated potable water from the YVWD's Regional Water Treatment Plant In accordance with the Adjudication, YVWD's share (13.58%) of the reallocated unused overlier pumping right was determined by Watermaster for 2018 through 2022 and reported in the 2018 Watermaster annual report. To project the amount available under more long-term conditions, BCVWD made an evaluation of a fully developed condition of the developable overlier parcels as shown on the worksheet in the spreadsheet. BCVWD believes the total unused overlier right at build -out will be about 1,800 AFY; YVWD's share will be about 240 AFY (rounded).
Both Mesa Verde and Summerwind Ranch are part of the original Oak Valley Development that started with the Landmark Land Company of California in the 1980s. The original Landmark Project was a master planned golf/recreational development. Oak Valley Partners (OVP) took over the project and were involved in the Beaumont Basin Adjudication. OVP has overlying groundwater rights in the Beaumont Basin [originally 1,806 AFY but reduced to 1,398.9 AFY, (round to 1,399 AFY), after the safe yield was reduced in 2014]. These overlier groundwater rights will be transferred to YVWD to serve the Summerwind Ranch development only per YVWD.
YVWD uses 700 gal/day/EDU (0.78 AFY/EDU) for total water demand for existing EDUs; but requires all new development to be dual -plumbed and requires the use of recycled water outside.
Potable water demands are estimated by YVWD to be 40% of the total water demand, i.e. 280 gal/day/EDU (0.37 AFY/EDU) with the remainder, i.e., 420 gal/day/EDU to be recycled water. It is BCVWD's opinion that the Adjudication requires OVP to forebear the pumping of their 1,399 AFY overlier pumping right, on an acre -ft by acre -ft basis, for both potable and recycled water.
YVWD has groundwater banked in the Beaumont Basin; at the end of 2018, per Watermaster, the amount in storage was 16,633 AF. YVWD has a 50,000 AF storage account.
The Mesa Verde WSA indicates 1,200 AFY is proposed to be recharged (banked) by YVWD from 2020 through 2040. YVWD developed a strategic plan entitled The Integration and Preservation of Resources for a Sustainable Future (adopted August 2008) which identified a groundwater banking program for future reliability for droughts and disruption in the SPW supply. The Plan indicates a Board policy of banking 15 percent of the total water supply used by the YVWD's customers. Data was not available to confirm the 1,200 AFY in Table 6-4, but 1,200 AFY is used in the spreadsheet model.

Table 6-4 also identifies "New Development Long -Term Supply - Sustainability Program" which relates to YVWD's Strategic Plan for a Sustainable Future. YVWD requires all new developments to provide funding to secure 7.0 AF of supplemental imported water per EDU. This amount of water is sufficient to meet the drinking water demands generated by each new EDU for a period of 20 years. YVWD also offers a Crystal Status Development Program whereby the developer provides funding for 15.68 AF of supplemental imported water per EDU which is sufficient to meet the potable and non -potable (recycled) water demands of the new EDU for 20 years. The difference between the two programs is that under the standard (7.0 AF/EDU) program, development will be restricted, (i.e., no grading or building permits will be issued), when a Stage 2 water shortage is declared (10% cutback). However, Crystal Status Development can continue through a Stage 4 Shortage (35% cutback). The 7.0 AF/EDU will not need to be replenished for 20 years. For this spreadsheet, the Standard 7.0 AF/EDU imported water purchase and storage is used, since it is difficult to determine how many new developments will purchase Crystal status.
This is conservative.
The spreadsheet assumes that 7.0 AF/EDU will be applied to all new developments (Mesa Verde and JP Ranch) in YVWD, except for Summerwind Ranch, which has overlier pumping rights available to meet its projected demands.
Table 6-5 presents a summary on the Supply -Demand Spreadsheet Model for YVWD in the SGPWA service area, i.e., principally the City of Calimesa. Year 2040 data was projected from previous years since the model currently only extends to 2035.
Table 6-5 was based on the following criteria:
• 2017 Ending Potable Water Demand: 500 AFY
• New EDU water demand: 0.37 AFY/EDU
• Existing EDU water demand: 0.78 AFY/EDU
• Water demand reduction from conservation on new EDUs: 10% • Water demand reduction from conservation on existing EDUs: none

Water Supply Assessment
Table 6-5 indicates that YVWD, in SGPWA service area has sufficient local supply to meet demands until 2025, at which time imported water will be needed unless YVWD plans on withdrawing water from their storage account. The YVWD Beaumont Basin Groundwater Storage Account is full in 2030 primarily because of the "Sustainability Water" which is banked.

Prior "proposed" projects equivalent dwelling units within the BCVWD service area were estimated at 12,544 (Legacy Highlands WSA, June 2020). The BP Project site was previously planned with a land use density of 2,000 equivalent dwelling units (EDUs). The new BP land use plan estimates a significantly reduced density of 360 EDUs, representing a reduced site density by 82 percent. The update presented in Table 6-6, as calculated in Section 4.2, is updated with this lower density for BP contributing to total EDU count of 10,904, and a reduction by 1,640 EDUs. Figure 4 shows the number of single-family home building permits issued in the City of Beaumont since year 2002. (Year 2018 was estimated based on data through September 2018.) Although not shown in the figure, the permit applications started to increase in 1999- 2000 and reached their peak in 2005 with 2,300 new home permits issued for that year. The number of
Beaumont Pointe
Water Supply Assessment
permits for new homes declined to a low of 169 in 2011. Over the last 10 years, permits averaged 396 per year, and 508 over the last 5 years. The 16 -year average was 747 per year. Future growth will likely be in the range of 450 to 650 permits per year, although some developers have projected slightly higher amounts in their build -out forecasts.

6.1.3.2 Cherry Valley Growth and Development
The ultimate build -out population for that portion of Cherry Valley served by BCVWD, based on the Pass Area Land Use Plan8'9 densities, was estimated to add a population of approximately 21,700, or about 7,750 EDUs. This was BCVWD's estimate in 2009 using GIS land use data from Riverside County and typical development densities for the various land uses in the General Plan. This estimate included a population growth of 6,736 in the City of Calimesa. BCVWD will not be serving the City of Calimesa as this is within YVWD's service area. Cherry Valley population is being reviewed as part of the 2020 UWMP update work in conjunction with the City of Beaumont's General Plan Update (2020). As a result, the increased population estimate to be served by BCVWD may be overestimated. BCVWD now believes it to be closer to 15,000 people at build -out, or about 5,350 EDUs. The build -out population is based on an increase from the current 2.43 persons per EDU to 2.8 persons per EDU projected at build -out.
The housing unit count within Cherry Valley was 2,874 in 2010 per the census data, but 26.6 percent of those are mobile homes. Adjusting for the reduced water use in mobile homes, the 2,874 housing units are equivalent to about 2,485 EDUs. The Sunny Cal Egg Ranch Development (529 EDUs from Table 6-6), is included with the City of Beaumont's development projects, but is actually within the current Cherry Valley census area. The Sunny Cal EDUs would have been included in the projected 2,865 EDU increase for Cherry Valley, (5,350 EDUs — 2,485 EDUs). To avoid "double counting EDUs," the Sunny Cal Egg Ranch EDUs were deducted from the 2,865 EDUs, resulting in a net projected 2,336 EDU increase for Cherry Valley to build -out. 8 Pass Area Land Use Plan, October 7, 2003, Part of Riverside County General Plan. 9 The Pass Area Plan, County of Riverside General Plan Amendment 960, Draft March 2014.
Beaumont Pointe
Water Supply Assessment
The buildout population and EDUs will be revised in future updates of the BCVWD Potable Water Master Plan and UWMP.
BCVWD believes Cherry Valley will be growing at a low rate keeping with its character of residential rural community, which is estimated to be less than 10 EDUs/year until the City of Beaumont's currently planned projects are developed. Once the City of Beaumont has developed, Cherry Valley will begin to be developed at a gradually increasing rate, perhaps increasing to 30 to 50 EDUs/year, but this is not expected to occur until after 2040.
6.1.3.3 Supply Demand Model for BCVWD
Table 6-7 presents a summary of the spreadsheet model for BCVWD's demand which was based on the following criteria:
• 2019 Ending Potable and Non -potable Water Demand: 13,337 AFY • New EDU water demand: 0.546 AFY/EDU
• Existing EDU water demand: 0.62 AFY/EDU
• Water demand reduction from conservation on new EDUs: 5% • Water demand reduction from conservation on existing EDUs: 5%

[1] Previous BCVWD planning identified Years 2020-2024 with 580 EDU/yr, and old JRT starting in 2030at80 EDU/yrfor25 years (Hidden Canyon WSA, Table 8). BP (JRT) update proposes 360 EDUs and buildout in 2022; therefore, 2022 EDUs/yr = 580 + 360 = 940. As such, EDUs/year for 2030, 2035 and 2040 decrease by50 EDUs/yr, 80 EDUs/yr, and 90 EDUs/yr, respectively. NOTE - 360 EDUs is the Project's Total Potable and Non -Potable Demands
[2] Adjusted for Year 2019, which was 13,129 AFY for 2018 (Legacy Highlands WSA, Table 12); 381 EDU/yr*0.546AFY/EDU = 208 AFY. [3] Year 2022 adds 2 years at Year 2020 EDU rate at 0.546AFY/EDU plus 197 AFY for BP (updated demand estimate) = 14,498 AFY. [4] Accounts for 423 EDU's in 2023, 381 EDU's in 2024, and 460 EDU's in 2025. The Project's 197 AF demand is accounted for in the 2022 column. [5] Accounts for 500 EDUs in 2026, 525 EDUs in 2027, 519 EDUs in 2028, 510 EDUs in 2029, and 502 EDUs in 2030. The District's previous projection accounted for 50EDUs in the first of year of construction (2030) of the orginal (residential) BP Project. The current Project's 197 AF demand is accounted for in the 2022 column.
[6] Accounts for 474 EDUs in 2031, 467 EDUs in 2032, 456 EDUs in 2033, 402 EDUs in 2034, and 368 EDUs in 2035. The District's previous demand projection accounted for 80 EDUs/yr from 2031-2033, and 90 EDUs/yr in 2034 and 2035 for the original (residential) BP Project. The current Project's 197 AF demand is accounted for in the 2022 column.
[7] Assumes forbearance water credit for Sunny Cal Egg Ranch will be 100 AFY by Year 2022. [8] Based on proportionate deliveries of recycled water from Year 2020 (1,556 AFY) to 2025 (2,188 AFY), or 126.4 AFY x 2 yrs increase. [9] For conservative analysis, assumes no increase from Year 2020. [10] Per Beaumont Basin Watermaster2018Annual Report, Section 3.5. [11] Per Beaumont Basin Watermaster2018Annual Report, Table 3-7. [12] Demand data presented in Table 6-7 represents the most reasonable and accurate demand projections to date. It should be noted that the District is currently analyzing current and future projected demands to be included in its 2020 Urban Water Management Plan Update, which will be submitted to the Department of Water Resources around July2021. Demands presented herein may be subject to change at the discretion of the District. Demand values currently presented are considered to be conservative. [13] Assumes uniform 207 EDU/yr increase from 2036-2040; The District's previous demand projections did not extend to 2040. This is considered to be conservative. It is assumed that the 90 EDU/yrtrend would continue from 2036-2040 for the original (residential) JRT Project. The current Project's 197 AF demand is accounted for in the 2022 column.
BCVWD's source of supply consists of:
• Edgar Canyon (Little San Gorgonio Creek) Groundwater - The annual yield for Edgar Canyon is based on 37 years of pumping records. The average annual production for the period 1983 - 2019 was 2,094 AFY, which was rounded to 2,100 AFY in the spreadsheet. However, for 2018, the production was reduced to 1,700 AFY to account for the reduced production in some wells due to reduced pump efficiency.
These pumps have been refurbished and will be refurbished on a regular basis.
Beaumont Pointe
Water Supply Assessment
• Beaumont Basin
o Reallocated Unused Overlier Pumping Rights — Watermaster provided the amount of reallocated overlier rights in the 2018 Annual Report for each year up to 2023. BCVWD was allocated 1,905 AF in 2019 and 1,962 AF in 2020.
Thereafter, BCVWD made an estimate based on production and development of the overlier's property. BCVWD estimated the long-term, fully developed, unused overlying party pumping rights would be about 1,800 AFY. BCVWD gets
42.51 % of the unused overlier pool each year. At full development, BCVWD estimates its share is 760 AFY.
o Forbearance Water is credited to a water supplier by Watermaster for any potable and/or recycled water provided to an overlier when the overlier's property develops. The overlier forbears pumping the equivalent amount of water supplied. BCVWD will supply the Sunny Cal Egg Ranch Development with both potable and recycled water. Sunny Cal Egg Ranch and associated partners are overlying parties and have pumping rights. BCVWD estimates that fully developed demand from recycled and potable water is about 340 AFY. The amount of forbearance water will increase over time from zero (0) AFY to 340 AFY as the project develops to anticipated buildout in 2030. o Water from Groundwater Storage — BCVWD has an 80,000 AF storage account in the Beaumont Basin. As of the end of 2018, there were 34,794 AF in storage per Watermaster's 2018 Annual Report. BCVWD's plan, which is shown in BCVWD's 2015 UWMP, envisions banking from 1,000 AFY to 2,500 AFY to drought proof BCVWD. This is accounted for in the spreadsheet each year.
Should there be a year when the projected amount cannot be delivered by SGPWA, any deficiency will be made up in successive years when adequate supply is available. Table 6-7 shows that for average water supply conditions, banking is anticipated every year and no water will be withdrawn from storage. • Recycled Water from the City of Beaumont — The City of Beaumont is required by Regional Water Quality Control Board (RWQCB) Order No. R8 -2015-0026 to have recycled water put to beneficial reuse by March 1, 2020. The City started construction of the new wastewater treatment plant, reverse osmosis desalting unit, and the required brine line from the wastewater treatment plant to the Inland Empire Brine Line (IEBL), in San Bernardino. The City has completed and has an approved Title 22 Engineering Report for the Treatment Facilities. The City and BCVWD signed a Memorandum of Understanding (MOU) in 2019 which began the process of an agreement for purchase of recycled water by BCVWD from the new treatment plant. BCVWD and the City are working jointly on defining the pumping and storage requirements at the treatment plant.
The City will be the recycled water producer; BCVWD the distributor. BCVWD is in process of completing their Title 22 Engineering Report for the Distribution and Reuse Applications. BCVWD has developed draft rules and regulation for recycled water use and developed a cross -connection testing and control plan which has been approved by the SWRCB Division of Drinking Water. In the future, as more recycled water becomes available during the late fall, winter, and early spring, BCVWD and the City will develop
Beaumont Pointe
Water Supply Assessment
an advanced treatment facility and secure permits for groundwater recharge of the surplus effluent. BCVWD and City will discuss providing recycled water to the Oak Valley Greens and/or Tukwet Canyon Golf Courses in exchange for forbearance water which will increase BCVWD's potable water supply.
The BCVWD spreadsheet model is based on 0.25 AFY/EDU (225 gallons/day/EDU) connected to the City's wastewater system. The City is obligated to maintain a 1.8 mgd discharge to Cooper's Creek for habitat maintenance; the available recycled water accounts for this 1.8 mgd "loss." A capacity factor of 75 percent is applied to the available wastewater to account for brine discharge, recycled water used on the plant site for maintenance, and water contained in the biosolids, hauled off -site. • Storm Water Capture — BCVWD and Riverside County Flood and Water Conservation District (RCFWCD) are jointly working on a Santa Ana Watershed Project Authority (SAWPA) Grant Project to design and construct Beaumont MDP-Line 16 storm water capture project, also known as the Grand Avenue Storm Drain in Cherry Valley. The project is partially funded under the Integrated Regional Water Management Implementation Grant Program under Proposition 84. A detailed analysis of the runoff potential was performed using 77 years of daily rainfall records from the Beaumont Rain Gage with the runoff determined for each storm using the Natural Resources Conservation Service (NRCS) curve number method. An estimated 200 to 230 AFY can be captured with MDP-Line 16 project. Other projects, in and around the BCVWD recharge facility, will capture excess flow in both Brookside Ave and Beaumont Ave to increase the annual capture (long term average) to 250 AFY. • Other Local Water Resource Projects — BCVWD has several other local water resource projects which can be implemented including:
o High nitrate groundwater at the mouth of Edgar Canyon. This groundwater can supplement the recycled water/non-potable water system flow in the summer, high demand months, making well water available for potable water use.
BCVWD believes as much as 300 AFY can be captured and reused. o San Timoteo Canyon Extraction Wells to capture groundwater from the Beaumont Basin flowing into San Timoteo Canyon and also to capture City of Beaumont wastewater flow discharged to Cooper's Creek once the water has percolated and is no longer available for habitat maintenance. It is estimated that 400 to 800 AFY can be captured and put into the recycled water/non-potable water system to meet summertime demands.
o For purposes of this WSA, 250 AFY are assumed to be available with the initial phases of these projects.
• Imported Water from SGPWA -- The amount of imported water which BCVWD is able to purchase and recharge is only the amount left over after YVWD, the City of Banning, and others have purchased the amount each needs to meet their demands and banking.
The amount available from the SGPWA collectively is discussed later in this WSA.
BCVWD has entered into an agreement, and participated financially, with the SGPWA for a share of the yield from the Sites Reservoir Project. This is discussed later in this WSA.

6.2 Summary of Member Agency Imported Water Demands on SGPWA Table 6-8 presents a summary of the spreadsheet model demands for the City of Banning, YVWD/Calimesa, and BCVWD from Tables 6-2, 6-5, and 6-7 presented previously. The imported water demands include from 3,816 to 7,912 AFY for banking and drought proofing. Table 6-8 also includes a projected amount of imported water for member agencies in SGPWA that are not currently taking SPW. These amounts were taken from SGPWA's 2015 UWMP. BCVWD believes these amounts are conservative considering the growth rates in the SGPWA Area.

7.1 State Water Project (SWP) Table A
SGPWA's contract with the Department of Water Resources (DWR) states a Table A amount of 17,300 AFY. Table A is the maximum amount of water the SGPWA can convey through the SWP facilities. This amount of water is not available consistently every year. In fall of each year, DWR provides an initial delivery allocation as a percent of Table A depending on amount of water in reservoir storage and anticipated hydrologic conditions. The allocation can be increased or decreased depending on the precipitation during the winter; a final allocation is usually issued in spring and sets the amount of water available, as a percentage of Table A, from the SWP. Since 1992, the allocation has averaged about 65%. DWR has prepared a reliability study10 which indicated the SWP can deliver only about 62% of Table A (10,726 AF to SGPWA) in any one year. Table B -5B, in DWR's Bulletin 132-17, forecasts the amount of SPW delivered to SGPWA in future years at 10,380 AFY.
In the discussions over the DCP, experts believe the current SWP reliability will decrease over time to 48%, or possibly even lower, due to anticipated additional regulatory constraints to protect threatened and endangered fish within the Delta. The length of time over which this decline in reliability will occur is not certain, but to be conservative, it is assumed that by 2035, the SWP reliability will decrease to 48%. Implementation of DCP by 2030 to 2035 is expected to restore reliability to above 60%.
For planning purposes in the WSA, the SWP delivery reliability is assumed to decline at a linear rate from 2020 to 2035. Therefore, by the Year 2035, with a delivery reliability of 48%, the SGPWA can expect only about 8,300 AFY from the SWP. Once the DCP is in place, the reliability will be restored, and possibly improved, over its current 62% reliability. 10 DWR (2012). State Water Project Delivery Reliability Report 2011.

7.2 Yuba Accord Water
Through the Yuba Dry Year Transfer Program, the official name for Yuba Accord Water, SGPWA can purchase additional supplemental water from Yuba County Water District under an agreement." The amount of water available from the Yuba Accord varies year to year depending on hydrologic conditions. Yuba Accord Water has only been available, for purchase by SWCs since about 2009. Delivery "loss" (termed "carriage cost" in DWR's Bulletin 132 series), in the Delta is typically assumed by DWR to be 20% of the delivered amount, adjusted as needed based on water quality considerations, plus an additional 2 to 3% Delta Conveyance "loss." Records in the Bulletin 132 series indicate that SGPWA purchased Yuba Accord Water in four years since 2009 although Yuba Accord Water was available every year from 2009 through 2015 except 2011. Purchases by SGPWA averaged 374 AFY, with deliveries averaging 280 AFY (25% loss).
The amount of Yuba Accord Water available depends on the calculated Sacramento Valley Water Year Index. Between 75,000 AFY (Dry Years) and 140,000 AFY may be available depending on the Water Year Index. If all 22 SWCs decide to participate in a given year, SGPWA's share of the Accord Water is 0.21%, based on the proportion of SGPWA's Table A and the Total Table A of all 22 participants. If some SWCs do not want to participate in a given year, the allocation to each SWC is adjusted upward. SGPWA would normally get 158 AFY during a dry year and a maximum of about 294 AFY.
The SGPWA estimates that about 300 AFY, on the average, of Yuba Accord Water can be obtained.12 For purposes of this WSA, a conservative 30% total loss is assumed, which will reduce the amount that can be actually delivered to the Pass Area to 200 AFY. This is reasonable considering the past experience.
7.3 San Bernardino Valley Municipal Water District (SBVMWD Water) The SGPWA Board of Directors authorized the General Manager to sign the Surplus Water Sale agreement with SBVMWD to purchase up to 5,000 AFY of SBVMWD's Table A water in years that SBVMWD's Board of Directors declares a surplus13. The availability of SBVMWD surplus water depends on hydrologic and groundwater conditions within SBVMWD's service area per SBVMWD Ordinance 79. SGPWA has the right of first refusal on the first 5,000 AFY of surplus water. Assuming SGPWA exercises the right, the agreement states that SBVMWD must first offer 50% of the available supply to one or both agencies that are in both SBVMWD and SGPWA, i.e.
Yucaipa Valley WD and South Mesa Water Company. Fifty percent of the water and any additional water "left over," can be offered to other SGPWA retailers. The agreement is for a term of 15 years from the date of execution (terminates in 2033), but SGPWA intends to renegotiate the terms and extend to some point in the future. Execution of the agreement is anticipated soon.
SGPWA estimates, based on past hydrologic conditions, this is likely to occur about two years out of every five, or 40% of the time. This is equivalent to 2,000 AFY in any one year. The term 11 DWR (2008). Agreement for the Supply and Conveyance of Water by the Department of Water Resources for the state of California to the Participating State Water Contractors under the Dry Year Water Purchase Program, March 31.

of this agreement will be at least 15 years from now or until about 2032.14 For purposes of this WSA, the amount of water available from SBVMWD is 2,000 AFY until 2032.
7.4 AVEK-Nickel Water
In June 2017, SGPWA Board of Directors approved an agreement with the Antelope Valley -East Kern Water Agency (AVEK) for 1,700 AFY for 20 years (to 2037) with the right of first refusal to extend it for another 20 years. The water rights on the Kern River originally belonged to the Nickel Family, LLC that were sold to Kern County Water Agency (KCWA) and subsequently leased to other parties in various amounts. One portion (1,700 AFY) is under the control of AVEK, which offered the water to SGPWA. This water is not subject to the reliability issues of the SWP. Per the take -or -pay agreement, SGPWA must take all of the 1,700 AF each year or pay for 1,700 AF even if the SGPWA does not take all, or any portion, of it in any one year.
7.5 City of Ventura and Casitas Municipal Water District (Ventura Water) The Ventura County Watershed Protection District is one of 29 State Water Contractors, but the agency lacks the infrastructure at present to be able to take its 20,000 AFY of Table A water.
The County's Table A is allocated to three entities: City of Ventura (10,000 AFY), United Water Conservation District (5,000 AFY), and Casitas Municipal Water District (5,000 AFY). Up until 2018, these agencies sold their Table A water back to the "Turn -back Pool" (discussed later in this WSA). In 2018, the City of Ventura (Ventura) and Casitas Municipal Water District (Casitas MWD) entered into an agreement to exchange Table A water with SGPWA. BCVWD understands the SGPWA is also negotiating to enact an exchange of Table A water with Ventura (and possibly Casitas MWD) for year 2020.
The SGPWA may be considering extending it to a more long-term arrangement. The SGPWA Board of Directors, at the May 4, 2020 meeting, authorized the General Manager to sign the draft agreement presented at the board meeting and authorized staff to complete any and all actions required to document the CEQA exemption, including the filing of the Notice of Exemption, and develop and execute any agreements or documentation with DWR for the one-year deal.
Under the terms of the 2018 agreement, SGPWA received all of Ventura's and Casitas MWD's Table A water allocation for year 2018, or 5,250 AF considering the Department of Water Resources' 2018 final allocation at 35% (up from the original 30% in the draft agreement).
SGPWA paid all of the Transportation Capital, Transportation Minimum, Conservation Capital and Conservation Minimum charges. Finally, each party to the agreement would be responsible for paying the variable costs for pumping the water to their respective service areas.
The SGPWA is obligated to return 40% of the Table A water taken from Ventura and Casitas MWD within 10 -years, no later than the end of calendar year 2028. This amount would be from SGPWA's future Table A allocation, presumably during a "wet year". Ventura and Casitas MWD must initiate the request for return of the 40%, except they may not request return in any year that DWR has a Table A allocation of 30% or less. If the Table A allocation is between 30 and 50%, the two agencies will negotiate the delivery amount for that year. If there is any "balance" 14 SGPWA 2015 UWMP
Beaumont Pointe
Water Supply Assessment
remaining after the 10 -year period, the two agencies and SGPWA will negotiate alternative delivery methods which could include extension of the 10 -year period by five years rolling the balance into a long-term exchange, should that develop.
The SGPWA is also considering a more long-term water transfer with a State Water Contractor for a portion of their unused SWP Table A allocation. Based on recent information published by SGPWA, it appears that supply would potentially start at approximately 6,000 AF on an average year in 2020 and might decline to 3,500 AF in 2040 as that potential partner agency utilizes more of their Table A supplies.
Currently, a one-year deal is in process, and it is believed that the SGPWA is pursuing a longer - term arrangement. For the purposes of this WSA, a conservative approach will be taken and no long-term arrangement will be in place.
7.6 Delta Conveyance Project (DCP), formerly California Water Fix (CWF) The SWP was authorized in the Burns -Porter Act, also known as the California Water Resources Development Bond Act, passed by vote of the people in November 1960 (Proposition 1).
Construction on most of the basic facilities of the SWP was completed by 1975. Due to cost considerations, and the fact that initial project water demands are lower than design capacity, a number of the originally planned facilities were "scaled down" or deferred. Many have not been constructed to date for various reasons. One of those projects was the Cross -delta Facility known as the Peripheral Canal. As a result of the scaling down and facility deferments/cancelations, the SWP is not able to live up to its original delivery capacity. A number of other facilities were scaled down, deferred, or not constructed.
The Sacramento -San Joaquin Delta levees are vulnerable to seismic shaking; the Delta ecosystem continues to decline; flooding and saline water intrusion into the Delta impacts the water quality delivered to municipal and agricultural users during dry years; climate change, whether short-term (50 or 100 years) or long term 500 or more years, will cause increased water levels in the Delta further stressing vulnerable levees. The SWP dams and reservoirs were designed about 50 years ago with the hydrology of the times. Climate change will impact the operation of the SWP. Precipitation, which used to fall as snow and be stored in snowpack, will be in the form of rain which the reservoirs were not designed to accommodate. More and more water will be lost to the ocean in future years because of increased runoff and less storage.
The Delta Conveyance Project (DCP), intended to address some of these issues, proposes a dual, gravity tunnel conveyance system from north of the Delta extending south to the Clifton Court Forebay. At the southerly end of the tunnels, a new Clifton Court Pumping Facility would lift water from the tunnels into Clifton Court Forebay. The water would be pumped from Clifton Court Forebay by the State and Federal Central Valley Project pumps as they now do. About 9,000 cfs would be diverted from the Sacramento River into the tunnels and around the Delta improving water supply reliability and export water quality TDS. The cost for the DCP was anticipated to be shared 55% by the State Water Contractors and 45% by federal Central Valley Project Contractors. This allocation share may change depending on the number of Central Valley Project Contractor participants.

address February 12, 2019. Originally planned as Phase 1 of the CWF.
The Delta Conveyance Project (DCP) is moving forward. On January 15, 2020 DWR issued a Notice of Preparation (NOP) for the environmental work on the reduced -size project which started the scoping comment phase. The scoping comment period ended April 17, 2020. DWR will be considering the comments when the Environmental Impact Report is prepared. The draft EIR is expected to be out for review and comment in early 2021.
The Delta Conveyance Project Authority has been established for the design and construction of the DCP. A Delta Conveyance Financing Authority has been established to develop the financing. The DCP is anticipated to be funded by revenue bonds issued by the State or a Jojnt Powers Financing Agency with payment by State Water Contractors south of the Delta through their existing contracts with the DWR — extended as needed into the future. In addition to other federal, State and local permits, DCP requires changes to the water rights permits for the State Water Project (SWP) Debt Service taxes. White Papers No. 3 and 6 provide more details on the funding, etc. The DCP is not expected to be operational until Year 2035. Until then, the reliability of the SWP would gradually degrade over time to 48% without the DCP due to a variety of reasons.
The original CWF with its two -tunnel approach was projected to increase the future reliability of the SWP by 14% (DWR study) to 17.62% (Metropolitan study) resulting in an increase of the overall reliability to 62% or, in the best case, 65.62%. This is at or slightly above the current reliability. It is not known to what amount of reliability increase will result from the new DCP but, to be conservative, it is assumed the reliability will be restored to 60 to 62%.
Without DCP, SGPWA's reliable Table A would be 8,300 AFY (rounded, based on 48% of 17,300 AFY). The reliable Table A supply for SGPWA would increase from 10,380 AFY to 10,726 AFY at 60% and 62% reliability, respectively.
7.7 Sites Reservoir
Sites Reservoir is a proposed reservoir that would be located at the site of a cattle ranch in the eastern foothills of the Central Valley about 78 miles northwest of Sacramento and north of the Sacramento -San Joaquin Delta near the Town of Maxwell, CA. Sites Reservoir is not on any major stream; all water must be pumped into the reservoir. Sites Reservoir was part of the original California Water Project, but was deferred. The reservoir in the original project proposal would have had a surface area of about 14,000 acres and store between 1.27 and 1.81 million acre- feet depending on final project. The estimated water yield would be between 470,000 to 640,000 acre-feet per year, depending on yearly rainfall and environmental regulations, according to DWR. The original project cost estimate was over $5 billion.
The Sites Project Authority, a Joint Powers Agency, was formed in 2010 to be a proponent and facilitator, to design and potentially acquire, construct, manage, govern, and operate Sites Reservoir and related facilities. Flood flows in the Sacramento River, over and above that needed to meet the demands of existing water rights holders, would be captured and pumped into Sites Reservoir. The Authority prepared a Value Planning Study in October 2019 to identify alternatives which would make the project more affordable. The Report was completed in April 2020 which scaled down the original project.
Beaumont Pointe
Water Supply Assessment
A preliminary analysis indicated that reservoir sizes of 1.3 to 1.5 million acre-feet (MAF) with assumed diversion criteria would be able to provide enough water to meet current participant demands. The Tehama-Colusa Canal and the Colusa Basin Drain would be used as the conveyance systems. The recommended project includes 1.5 MAF and 1,000 cfs of release capacity into the Sacramento River or to the Colusa Basin Drain at Dunnigan, and 243,000 AFY long term yield, was estimated at a cost of $3.0 billion.
The project Authority stated the 21 agencies put up $27 million for planning and studies with another $19 million due October 2020 to continue the process. Sites reservoir was approved by the California Water Commission (CWC) for $816 million of Proposition 1 funding on July 24, 2018. The CWC also agreed to provide $40.8 million in early funding to assist in completing the needed environmental analyses and obtain permits.
SGPWA has made a financial commitment of 10,000 AF and BCVWD has committed to 4,000 AF (total 14,000 AF) to the Sites Project Authority to fund Phase 1 of the Sites Reservoir Study.
Reliability is between 65% (worst -case) and 100%15. The result is 9,100 AFY at 65% reliability.
Sites Reservoir will not produce water until about Year 2030; however, costs will be incurred by project participants moving forward. For the purposes of the WSA analysis it is assumed that water will not be available until 2035. The Authority's current plan will finance Phase 2 costs on a year -by -year basis.
The Sites Reservoir Project Authority is working closely with the federal Bureau of Reclamation to secure Bureau participation and funding which will reduce the cost to the participants. It is believed that the Authority would be responsible for 60% of the project cost, and the remainder from the State and federal agencies. This may change since the Authority anticipated slightly more Proposition 1 funding than the $816 million.
Although the Sites Reservoir is not expected to deliver water for another 15 years, currently the project is moving forward and is named in the Governor's Water Resiliency Plan. The project has been awarded a substantial CWC Proposition grant. The Sites Project Authority is continuing to refine its financing plan to fund the study phases. The reservoir is an "off -stream" reservoir giving it a reduced environmental footprint. Although there is some risk in the implementation, with each study phase completed the risk becomes less and the project is more certain.
7.8 Sale of State Water Project Contractors Restoration of DCP Reliability Benefits All `South of the Delta' SWP Contractors pay their proportionate share of the DCP costs. With the implementation of the DCP, there will be an increase in SWP reliability. Although all of the "South of the Delta" SWP Contractors will be paying their proportionate share of the DCP, for various reasons, a few SWP Contractors may not need the benefits of the increased yield and may be interested in transferring (selling) their incremental yield to other interested SWP Contractors, such as SGPWA. Currently, not enough is known about the sale of incremental yield and, therefore, will not be considered until it is better defined. 15 See White Paper No. 1, Table 3
Beaumont Pointe
Water Supply Assessment
7.9 Purchase or Leasing of Metropolitan's Original CWF Phase 2 Water With original CWF 2 -tunnel, 2 -phase concept, Metropolitan Water District of Southern California (Metropolitan) board of Directors voted to fund their share of the original CWF plus agreeing to fund the second phase of the CWF (second tunnel), i.e. the Central Valley Project share. This would have made water available for Metropolitan to sell/lease to other interested parties, e.g.
SGPWA. With the DCP scaled down to one tunnel, this does not appear to be an option any longer.
7.10 Other Sources of Imported Water
There are other sources of water available through the SWP which include:
7.10.1 Article 21 Water
Article 21 Water is water that is offered for purchase by DWR resulting from reservoir releases needed to accommodate impending storm or snowmelt runoff when water is still available after operational requirements for SWP water deliveries, water quality and Sacramento -San Joaquin Delta requirements are met. This water is available only on short notice and must be taken immediately. BCVWD has capacity in its groundwater recharge facility to accommodate Article 21 Water. SGPWA is constructing their own Fiesta Recharge Facility which can be used for Article 21 Water. Article 21 Water is in addition to the State Water Contractor's Table A amount.
An analysis of Article 21 Water availability indicated the amount available is highly variable and there is competition for the water. If the requests for purchase are greater than the available amount, it is typically allocated on the basis of the requestors' Table A. A review of recent purchases from 2002 to 2015, with up to 17 "buyers," indicated that if SGPWA were a purchaser, their share would be about 0.5% of the total available. (The large agencies tend to dominate the purchases.) Table 7-2 presents an analysis of Article 21 Water availability to SGPWA based on DWR records from 1969 — 2015. Two periods of time were analyzed: total record and recent record.

Article 21 water was available during the heavy snowfall year 2018-19 although the SGPWA was not able to take advantage of this since the BCVWD connection was out of service due to construction of the expanded turnout and the SGPWA's Fiesta Recharge Facility was not operational.
7.10.2 Turn -back Pool Water
Turn -back Pool Water is water that other State Water Contractors have ordered from DWR as part of their Table A entitlement, but decided they did not need the water that particular year and sold it back to DWR. DWR in -turn offers it for purchase at a relatively low set price to other State Water Contractors. Turn -back Pool Water has only been available since about 1996 following the Monterey Amendments to the State Water Contracts. Analysis of the data from 1997 through 2015, shows SWCs sold an average of 59,000 AFY of water back to the "pool" for purchase by other interested SWCs. (The median value was 29,770 AFY). Purchase of Turn -back pool water is also competitive, depending on hydrologic conditions. Assuming SGPWA's share is 0.5% based on the analysis of Article 21 Water, 295 AFY on the average could be purchased (149 AFY median). It would be reasonable that SGPWA could rely on about 200 AFY of Turn -back pool water.
7.10.3 Short-term or Long-term Water Transfers or Exchanges Short-term or Long-term Water Transfers or Exchanges is water that can be obtained through exchanges and transfers from other State Water Contractors who do not need all of their Table A water in a given year or years. There are opportunities almost every year.
7.10.4 Recommendations for SGPWA
There is considerable competition for the Turn -back Pool and Article 21 Water and its availability is uncertain from year to year. SGPWA can take advantage of this water whenever it is available, and can consider short term transfers whenever available. Transfers of SWC Table A is subject to the SWP delivery reliability.
7.11 Summary of Available Imported Water Supplies
Table 7-2 summarizes the range of imported water supplies available to SGPWA based on the current and potential sources presented above. Agreements are in place for Ventura- Casitas, AVEK-Nickel Water, and SBVMWD Surplus Water. SGPWA is one of the 22 SWCs that has signed on to the Yuba Accord. Their share of the Yuba Accord Water is 0.21 % of the available
Beaumont Pointe
Water Supply Assessment
water. In addition, through their State Water Contract, SGPWA can purchase Article 21 Water and Turn -back Pool Water.
The SGPWA has agreed to support the original CWF and participate in its funding, and it is assumed the SGPWA will support the DCP. BCVWD and SGPWA have made financial commitments to Sites Reservoir, and currently plan to contribute to future phases of the Sites Reservoir project.
Table 7-3 presents a summary of current and projected SGPWA imported water supplies, through 2040 in 5 -year increments based on the yields in Table 7-2. Figure 5 shows the sources of imported water supply and the regional imported water demand with and without banking and drought proofing.

Figure 5
SGPWA Imported Water Sources and Demand to 2040 (Worst Case Conditions) Until 2025, SGPWA has sufficient imported water to meet the demands of the City of Banning, BCVWD, YVWD/Calimesa as well as the demands from those SGPWA members currently not taking imported water. (Those agency total demands are shown in Table 6-8.) BCVWD has determined these are very conservative and it is unlikely that these areas will be developing to require those demands within the timeframe shown. It would be reasonable to believe that the Yucaipa/Calimesa to Banning area will develop more fully before moving into these outlying areas. Nevertheless, Table 6-8 shows that about 6,000 AFY will be banked regionally by the water suppliers between now (2020) and 2025, which is about 30,000 AF of additional water in storage for a total of 150,592 AF in storage by year 2025.
From 2025 to 2035 (when DCP and Sites Reservoir become operational), adequate imported water supply will be available to meet the imported water demands but with reduced amounts available for banking. The region's member agencies would still have nearly 145,000 AF in banked storage which could be used if needed. In a normal year, banking would continue in 2030, but at slightly reduced annual amounts until DCP and Sites Reservoir come on-line.
7.12 Contingency Plan
It is recognized that DCP and Sites could be delayed or perhaps reduced in size and capacity.
But, as these projects go through the design and permitting process over the next few years, these risks will be assessed. SGPWA can take action to supplement its existing supply with short-term exchanges and transfers from other agencies. If it is evident that DCP and/or Sites
Beaumont Pointe
Water Supply Assessment
Reservoir will be delayed indefinitely, the short-term exchanges and transfers can be converted to long-term transfers. An option is to extend the AVEK-Nickel Water Agreement for another 20 years to 2057 as allowed in the existing agreement. Another option is participating with other local agencies in other water resource projects such as groundwater, brackish water, or sea water desalination projects with water exchanges.
8. WATER SUPPLY AND DEMAND FOR BCVWD
Section 6.1.3 presented the water demand and water supply requirements, including imported water, under average hydrologic conditions for BCVWD. Section 7 quantified the imported water demands on the SGPWA from BCVWD and the other member agencies of the SGPWA. As presented in Section 7 and Figure 5, SGPWA will have enough, or has made commitments for or taken steps to acquire, imported water supply to meet its needs to year 2040 and beyond.
Since BCVWD's demands and imported water requirements are included in SGPWA's demands, including imported water, it can be concluded that BCVWD has sufficient supply and imported water to meet demands beyond 2040 under average demand and supply conditions.
It should be pointed out that 28.6% of the Sites Reservoir Project yield, (4,000 AFY/14,000 AFY) shown in Figure 5 above, is committed to BCVWD by virtue of BCVWD's financial commitment to the Sites Reservoir Project Phase 1 and Phase 2 - 2019. Figure 6 shows BCVWD's demand is less than the available supply. Figure 6 is based on the data in Table 6-7. Figure 7 shows the accumulated volume in BCVWD's Beaumont Basin groundwater storage account. By 2040, the storage account is almost full (77,294 AF in storage). Table 6-7 indicates that BCVWD's imported water demand will be 10,707 AFY in 2040; this means that BCVWD is projected to have 7.2 years of imported water demand in storage which can be used to supply water during drought periods even if no SPW is available.

9. WATER SUPPLY SINGLE AND MULTIPLE DRY PERIOD ANALYSIS The previous sections in this WSA analyzed a typical, normal or average, water supply year. The previous sections demonstrated there is adequate water supply both regionally and for BCVWD to meet the needs provided the projects and agreements identified are implemented. But, in addition to a "normal" year, the WSA requires a supply sufficiency analysis for critical dry year and multiple dry year conditions. The water supply conditions for these periods are presented in BCVWD's 2015 UWMP, Section 7, Water Supply Reliability Assessment. Key tables and information are extracted from the 2015 UWMP to support the analysis presented herein and updated. The scenarios evaluated in this section include:
• Single Critical Dry Year -- the lowest water supply available to BCVWD, a worst -case condition
• 2 Consecutive Dry Years -- the lowest average available water supply over a 2 -year period
• 3 Consecutive Dry Years-- the lowest average available water supply over a 3 -year period
• 6 Consecutive Dry Years-- the lowest average available water supply over a 6 -year period
BCVWD will be relying on banked water to provide the major portion of the supply during these periods.
BCVWD enjoys the benefits of a groundwater basin (Beaumont Basin) with very large storage capacity. BCVWD and its neighboring agencies in the San Gorgonio Pass Area take advantage
Beaumont Pointe
Water Supply Assessment
of this by banking imported water during wet years for use during extended droughts.
Complementing the large storage capacity is the fact that percolation and recharge occur at relatively high rates. It is very easy to "bank" water in the Beaumont Basin. It is retained in the Basin due to well -managed groundwater levels, and the ample storage capacity. Figure 8 shows the amount of water BCVWD has accumulated in its storage account since 2003. Imported water began to be spread in 2006. As of the end of 2018, there were 34,794 AF in storage. BCVWD's current maximum storage capacity is 80,000 AF. The figure shows the drop in storage in response to the drought in 2015 when there was very little imported water available for recharge and banking.

BCVWD Historic Beaumont Basin Groundwater Storage Account
9.1 Water Source Availability
The amount of water available during the dry periods from BCVWD's water sources are presented below.
9.1.1 Groundwater
9.1.1.1 Beaumont Basin
The Beaumont Basin is managed by the Beaumont Basin Watermaster under the principles of the Adjudication.
In any given year, BCVWD can pump out its stored (banked) water. The storage is replenished, at least partially, every year by forbearance water, reallocated unused Overlying Party pumping rights, and imported water when available. Recharge, using advanced treated recycled water from the City of Beaumont, will occur in the future. The amount of imported water that can be recharged in any year depends on DWR's SWP allocation. This varies from year to year.
Beaumont Pointe
Water Supply Assessment
The amount of unused Overlying Party rights is based on a 5 -year moving average and could decrease slightly during drought periods as the Overlying Parties use more groundwater to compensate for the lack of rainfall. The forbearance water will decrease during dry periods as users reduce water consumption.
Table 9-1 shows the estimated amount of water credited to BCVWD by Watermaster for a single or multiple dry year analysis. For the dry year analysis, it was estimated that there would be a 15% conservation effect; in other words, for dry year analysis, only 85% of average annual forbearance, reallocated Overlying Party rights, etc. would be available. In Table 9-1 the 15% reduction factor is also applied to the recycled forbearance water to account for a potential reduction in treated wastewater due to water conservation effects.

9.1.1.2 Edgar Canyon
Groundwater from Edgar Canyon is affected to some degree by climate. The average annual extraction from Edgar Canyon is 2,094 AFY (rounded to 2,100 AFY) based on records from 1983- 2019. During that period of time the minimum extracted was 1,117 AFY, which occurred in 1991.
This can be considered the "Single Dry Year Water Available." The 2 -year, 3 -year, and 6 -year moving averages for the extractions from 1983-2019 were determined and are presented in Table 9-2 along with the Base Period for moving averages.

9.1.2 Imported Water
The amount of imported water available from the SGPWA via the State Water Project is climate dependent. A spreadsheet was developed using the 2015 DWR Delivery Capability Report simulation data (1922 to 2003) for SGPWA to develop an estimate of the delivery capability for the single dry year and multiple dry year reliability analysis. The 2-, 4-, and 6 -year moving averages of annual estimated delivery allocations were determined for the period 1922-2003. A summary of the Table A delivery percentages is shown in Table 9-3.

The percentages in Table 9-3 were compared to actual SWP delivery allocations for the period 1992 to 2020, a 28 -year period:
Minimum year 5% (2014)
Minimum 2 consecutive years 12.5% (2014-15)
Minimum 3 consecutive years 20% (2013 — 15)
Minimum 6 consecutive years 40% (2013 — 18)
The actual minimum year and minimum 2 and 3 consecutive years allocation percentages are less than those reported in the 2017 DWR SWP Delivery Capability Report. The 2017 Report replaced the 3 -year statistic with a 4 -year statistic but is conservatively assumed to be an equivalent measure. Therefore, for the reliability analysis in the BP WSA, the lowest allocation percentages were used, as shown in Table 9-4:

It should be noted that not all SGPWA imported water sources will be available during extended dry periods.

issues and is available every year until termination of the existing agreement in 2037. The Delta Conveyance Project reliability recovery water and the Delta Conveyance Project Side Deals would be available during extended dry periods but are subject to the average Table A delivery percentages as SPW in Table 9-4.
During dry periods San Bernardino Valley MWD Surplus Water, Article 21 water, and Turn -back Pool Water would likely not be available and should not be counted on for supply. Similarly, the availability of short and long term exchanges are unlikely, which would also include any additional Table A Water should SGPWA be able to secure a long-term exchange contract with the Additional Table A SGPWA Partner Agency.
The Sites Reservoir Project was designed to be a dry period flow augmentation project. Excess storm flows in the Sacramento River are diverted and pumped into Sites Reservoir, stored, and released back into the Sacramento River during dry periods. Data from the Sites Project Authority submitted with their application to the California Water Commission for Proposition 1 Funding was used to determine the amount of water which could be depended on during dry periods.
Figure 9 (borrowed from Sites Reservoir Project Authority's Proposition 1 Application Executive Summary) shows the dry year benefits based on 82 years of hydrologic simulation using the CalSim II ModeI16

It is important to note this is a preliminary estimate developed prior to the Value Planning Analysis.
The modeling that was performed for the application was prescribed by the California Water Commission and includes the effects of climate change. For the analysis in the BP WSA, the year 2030 values will be used for 2030 through 2040. The "critical" volume will be used for all the dry period analyses to be conservative.

Table 9-10 presents a summary of total SGPWA regional imported water demand and the imported water supply available during the single and multiple dry years. The demand does not include the "banking" demand, since "banking" would not be occurring during years when imported water supply is reduced. Table 9-10 shows the conditions when the imported water demand exceeds the supply which will require SGPWA's member agencies, like BCVWD to withdraw water from their storage account. The supply of imported water is less than the demand until Sites Reservoir comes on-line about year 2035.

When the demand for imported water exceeds the supply, it is reasonable to assume the imported water will be allocated in proportion to the member agency's fraction of the total imported water demand without banking. Table 9-11 shows the allocation percentages.

9.1.3 Recycled Water
Recycled water from the City of Beaumont is consistently available; although during droughts, consumers are more aware of water conservation and reduce their indoor water consumption somewhat. They are more aware of the need to do only full loads of laundry, full loads for the dishwasher, etc. Agencies, including the City of Beaumont, have observed a reduction in wastewater flows during the recent drought.
The average year amount of recycled water from the City of Beaumont is taken from Table 6-7.
As stated in the discussion for Table 6-7, the total wastewater produced by the City is reduced by
1.8 mgd for habitat maintenance, and a capacity factor of 75% was applied to the remaining water to account for brine and other losses. For a single dry year, an estimate of 90% of the normal, average recycled water will be available. As the drought becomes more pervasive, the amount of recycled water is estimated to reduce further to 85% of normal. Table 9-13 provides an estimate of the available recycled water during extended dry periods from the City of Beaumont.

9.1.4 Storm Water and Other Local Water Resources
Storm water and Urban Runoff quantities are dependent on rainfall. Review of the rainfall record at Beaumont for the period 1888 — 2006 resulted in the data shown in Table 9-14. To determine the multiple dry year rainfall as a percent of the average rainfall, the 2-, 3-, and 6 -year moving averages of the annual rainfall was determined.

9.2 Water Demands During Critical and Multi -year Dry Periods Table 6-7 showed the average BCVWD water demands (potable and non- potable). These demands are used in the Dry Period Reliability Analysis below for the 1, 2, and 3 consecutive year dry periods, primarily because there may not be enough time to implement water demand restrictions and see the effect of these restrictions on demand. However, for the 6 consecutive year dry period, it is assumed the water shortage contingency planning actions set forth in Section 8 of BCVWD's 2015 UWMP would be in effect and at least a 15% reduction in demand would be obtained. This is over and above the nominal water conservation efforts envisioned in the development of the average demands in Table 6-7. Water supply for single dry year, 2 consecutive dry years, 3 consecutive dry years, and 6 consecutive dry years are presented in Tables 9-15 through 9-18 respectively.

Water Supply Assessment
Table 9-15 through 9-18 demonstrate BCVWD can provide water to the planned developments listed in Table 6-6 (Section 6) which include the Beaumont Pointe development project during critical dry year and multiple dry year periods by relying on BCVWD's Beaumont Basin Groundwater Storage assuming DCP and Sites Reservoir are on-line as planned. BCVWD will need to maintain 25,713 AF of water banked in storage to meet the 6 -year dry period by the time Sites Reservoir and the DCP are "on-line." This is not an unreasonable amount of storage considering BCVWD has an 80,000 AF storage account and as of the end of 2018, 34,794 AF in storage.
Table 6-7 provided BCVWD's Beaumont Basin storage account balance under the basis of average water supply conditions assuming the development projects listed in Table 6-6 were constructed. Table 6-7 shows a steady increase in projected groundwater storage from 35,794 AF in 2020-22 to approximately 77,294 AF in the year 2040. To achieve this level of storage, BCVWD will be banking additional water for drought proofing to supply water during critical and multiple dry year period.
The water banking pursuant to BCVWD's 2015 UWMP:
BCVWD's plan, which is shown in BCVWD's 2015 UWMP envisions banking anywhere from 1,000 AFY to 2,500 AFY to drought proof new development. This is accounted for in the spreadsheet each year. Should there be a year when the projected amount cannot be delivered by SGPWA, any deficiency will be made up in successive years when adequate supply is available".
In addition to BCVWD, YVWD/Calimesa and the City of Banning have storage accounts which when combined with BCVWD's will have an estimated 117,800 AF in storage as of the end of 2021. Tables 6-2 and 6-5 (Section 6 herein) show that the storage accounts for YVWD/Calimesa and the City of Banning these agencies are projected to have 50,000 and 76,510 AF, respectively, in storage by 2040. When combined with BCVWD's projected storage account balance, on a regional basis there will be over 200,000 AF in banked storage — more than ample to meet the needs during short-term droughts.

Water Supply Assessment
10. CONCLUSIONS
1. The projected water demand from the Beaumont Pointe development project is 197 AFY of which 85.2 AFY is outdoor, non -potable water use. This compares to BCVWD's current demand of 13,668 AFY (estimated for 2020).
2. The Beaumont Pointe development project site was included in the list of planned development projects in BCVWD's 2015 UWMP (previously identified as Jack Rabbit Trail) which demonstrated adequate water supplies upto the year 2040. The BP project site was previously planned with a land use density of 2,000 equivalent dwelling units (EDUs). The new BP land use plan estimates a significantly reduced density by 1,640 EDUs for a new proposed Project total of 360 EDUs, representing reduced site density and water demand by 82 percent.
3. BCVWD prepared a series of White Papers which analyzed the regional (SGPWA) imported water supply requirements and funding requirements. These White Papers are referenced for the BP WSA. The basis for the White Papers was a regional spreadsheet demand model, developed by BCVWD, which was reviewed by the City of Banning and YVWD.
4. The White Papers indicate that SGPWA can obtain sufficient imported water supply to supplement local supplies to meet regional needs including BCVWD's needs. The White Papers also indicated that adequate funding is available to implement the imported water projects currently planned for the short and long terms.
5. BCVWD prepared and adopted a Potable Water Master Plan which identified water needs and facility needs to build -out. The BCVWD 2015 UWMP identified recycled water from the City of Beaumont for non -potable water irrigation with a plan for the recharge of surplus recycled water with appropriate treatment and permits. The City and BCVWD signed a Memorandum of Understanding (MOU) in 2019 which began the process of an agreement for purchase of recycled water by BCVWD. In addition, storm water capture and other local water resource projects were identified. One of these projects, MDP-Line 16, (Grand Avenue Storm Drain) is currently in design by the Riverside County Flood and Water Conservation District and BCVWD. The storm drain will be partially funded through a grant from the Santa Ana Watershed ProjectAuthority.
6. SGPWA and BCVWD have made financial commitments to the Sites Reservoir project Phase 1 studies and will commit funds to Phase 2.
7. Adequate water supply exists, or is planned, for the Beaumont Pointe development project to 2040 and beyond as outlined in Tables 9-6 through 9-9. BCVWD can meet the Project needs as well as BCVWD's existing demands and the demands of the other planned developments within BCVWD's service area which are listed in the BP WSA.
8. Multiple dry -year reliability analysis demonstrates that BCVWD will be able to meet its existing demands and the demands of the other planned developments within its service area which were listed in the BP WSA. BCVWD will supplement its existing supply sources during these dry periods with banked water in BCVWD's Beaumont Basin Groundwater Storage Account.

Water Supply Assessment
9. Pursuant to §10910 of the California Water Code (SB 610) and information provided in the BP WSA, BCVWD has determined that currently available and planned supplies are sufficient to meet the water demands of the proposed BP project in addition to the existing and other planned project demands during normal, single dry and multiple dry years over the next 20 years, as outlined in Tables 9-15 through 9-18.
10. Pursuant to the California Government Code Section 66473.7, (SB 221) BCVWD has determined that it has sufficient and adequate water supply available to serve the long- term needs of the Beaumont Pointe in addition to the existing and other planned project demands during normal, single dry and multiple dry years over the next 20 years, as outlined in Table 9-15 through 9-18.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 2 of 57 1 Background and Purpose for Addendum
1.1 Background
The Beaumont Pointe Development "Project", previously referred to as the Jack Rabbit Trail Development, is located in the City of Beaumont, CA. The Project will be a new 625 -acre industrial, commercial, and recreational complex constructed south of the CA -60 freeway and northwest of the proposed Hidden Canyon Development. The Project will consist of general commercial/retail land uses and five large industrial warehouse buildings totaling approximately 5.0 million square feet of floor space.
The Project is currently proceeding with filing an EIR and seeking incorporation into the Beaumont Cherry Valley Water District (BCVWD) and, by association, the San Gorgonio Pass Water Agency (SGPWA).
The Project will be located in the Beaumont Cherry Valley Water District's ("District") sphere of influence.
The Project's potable water (PW) and fire flow demands are proposed to be provided from the District's 2650 pressure zone, which currently serves the westerly part of the District's service area, south of Interstate 10 and west of Cherry Valley Blvd. As part of on -going water conservation efforts and the Project's plan of service with the District, all outdoor irrigation demands will utilize non -potable water (NPW) distributed by BCVWD.
From 2018 through 2021, the Project worked with the District to complete a Water Supply Assessment (WSA), dated April 13, 2021. The Beaumont Pointe Development WSA was originally based on the District's 2015 Urban Water Management Plan (UWMP) and continuously updated with the most current information from the SGPWA / District's "White Papers", which contained the most current updated calculations and projections for imported water supplied from SGPWA and local groundwater supplied from BCVWD for their committed service area. During the District's June 9th, 2021 Board Meeting, the 2021 Beaumont Pointe WSA was presented and approved by the District's Board of Directors.
Subsequently, the District provided the Project with a conditional Will Serve Letter, which stipulated that the District will provide water service to the Project. The Project is currently working with the District on a Plan of Service document required by the Will Serve Letter.
In August 26, 2021, four months after approval of the Beaumont Pointe WSA, the District Board of Directors approved the 2020 BCVWD UWMP, updating the District's 2015 UWMP to be in compliance with State law. Specific to the Beaumont Pointe Development, the 2020 BCVWD UWMP incorporates the specific change in land use from residential to commercial, reducing the total water demand for the Project from 2,000 Equivalent Dwelling Units (EDUs) to 360.26 EDUs, a reduction of 82%. Additionally, the 2020 BCWD UMWP further defines the District's and City of Beaumont's commitment to using non - potable water, available from the City's upgraded Title 22 recycled water treatment plant and shallow aquifer wells, which are not suitable for direct potable water supply. This is consistent with the approved Beaumont Pointe Development WSA, which indicated 43.31% of the total demand could be supplied by BCVWD's non -potable water system. Doing so reduces the Project's imported and local ground water (potable) demand further, from 360.26 EDUs to 204.21 EDUs.
1.2 Purpose for Addendum
State law indicates that the WSA for a project shall utilize the most recent UWMP (See Water Code Section 10910 (c)3), which states that if the projected water demand associated with the proposed project was accounted for in the most recently adopted urban water management plan, the public water system may incorporate the requested information from that plan in preparing the WSA. As mentioned above, the water demand information presented in the approved Beaumont Pointe WSA utilized the District's most up to date calculations from the "White Papers" and therefore, the water demand values are consistent with the adopted BCVWD 2020 UWMP. However, the approved Beaumont Pointe WSA also indicated that it was based on the BCVWD 2015 UWMP and therefore, the document did present tables and information about the general service areas from both the SGPWA and BCVWD 2015 UWMPs, which the Project wishes to now update with this Addendum. The BCVWD 2020 UWMP includes the Beaumont Pointe Development water demands and indicates that the District can meet its service area's water supply requirements under normal, single, and multiple consecutive dry years.
August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 3 of 57 Since Beaumont Pointe Development's overall water demands did not change (outdoor irrigation demands will utilize NPW as discussed further), and since the updated BCVWD 2020 UWMP included the Project's demands and verified the District can satisfy the service area's demands under the required conditions, the purpose of this addendum is the following:
• Identify, summarize, and provide modified and/or replacement language to the Project's previously approved WSA for differences between the SGPWA and BCVWD 2015 and 2020 UWMPs referenced in the Project's WSA. Specifically, this includes the following:
o As indicated in the BCVWD 2020 UWMP and the previously approved Beaumont Pointe Development WSA, update the Project's WSA to further define the use of NPW supplies for all outdoor irrigation demands.
o Update the SGPWA and BCVWD data and tables presented in the Beaumont Pointe Development WSA with the current data and tables from agency's 2020 UWMPs. o Update the SGPWA and BCVWD data and tables for the projected future water supplies and demands of BCVWD for the required 20 -year projection (through 2045) under normal, single, and multiple consecutive dry year conditions. o Add a new section summarizing the BCVWD 2020 Water Shortage Contingency Plan referenced in the BCVWD 2020 UWMP.
August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 4 of 57 2 2021 Beaumont Pointe WSA Updates
As part of this addendum, the following lists the revisions, additions, and/or deletions that shall be made from the existing sections in the approved April 13th, 2021 Water Supply Assessment for the Beaumont Pointe Development.
Section 1. Introduction
Within Section 1, the second paragraph shall be removed and replaced with the following. This revision adds language reflecting the Project's utilization of NPW for all outdoor irrigation demands as discussed during the Project's Plan of Service. Additionally, this revision includes a brief introduction to the planning of the Project in the updated BCVWD 2020 UWMP.
The Project was previously planned and included in the BCVWD's 2015 UWMP with a land use density of 2,000 equivalent dwelling units (EDUs) (previously identified as Jack Rabbit Trail).
Based on the District's adopted EDU usage factor of 0.546 AFY/EDU, this equates to an estimated water demand of 1,092 AFY. The new Beaumont Pointe Development land use plan, consisting primarily of industrial warehouse buildings, estimates a density of 360.26 EDUs. The originally approved Beaumont Pointe Development WSA indicated that approximately 43.31% of the potable water demand from the 360.26 EDUs could be served by BCVWD's Non -Potable Water (NPW) system reducing the Project's potable water demand to 204.21 EDUs. As part of the Project's Plan of Service documents and ongoing water conservation efforts, the Project will be designed to utilize NPW for all outdoor irrigation demands.
To clarify, when the District was preparing the basis for future water demands within the District's service area in the BCVWD's 2020 UWMP, the District utilized the potable water demands from the DRAFT November 2020 Beaumont Pointe WSA. This draft version of the Project's WSA identified the potable water demand as 221 EDUs as shown in Table 3-7 in the BCVWD's 2020 UWMP. Because the Project's updated land use plan has a potable water demand of 204.21 EDUs, the District's 2020 UWMP conservatively included the Project's anticipated potable water demands at 221 EDUs.
Section 3.1 Background
The fifth paragraph shall be removed and replaced with the following. This revision updates 2015 UWMP references with the applicable BCVWD 2020 UWMP updates showing the District's latest UWMP has considered the Beaumont Pointe Development in their updated water supply assessments.
Like SB 221, SB 610 specific levels of supply reliability are not mandated (i.e., whether a specific level of demand can be met over a designated frequency); rather, the law provides that it is a local policy decision of the water provider as part of the planning process. As provided for in the law, the WSA can rely on the data in the latest UWMP in assessing the water demand of the proposed project relative to the overall increase in demands expected by BCVWD. The Beaumont Pointe development project site was included in Table 3-7 of BCVWD's 2020 UWMP (previously identified as Jack Rabbit Trail). The Project site was previously planned for the development of single-family residences with a land use density of, and corresponding water demand for, 2,000 equivalent dwelling units (EDUs). Based on the District's adopted EDU usage factor of 0.546 AFY/EDU, this equates to an estimated water demand of 1,092 AFY. The new Beaumont Pointe Development land use plan, consisting primarily of industrial warehouse buildings, estimates a density of 360.26 EDUs. The originally approved Beaumont Pointe Development WSA indicated that approximately 43.31% of the potable water demand from the 360.26 EDUs could be served by BCVWD's Non -Potable Water (NPW) system reducing the Project's potable water demand to 204.21 EDUs. As part of the Project's Plan of Service documents and ongoing water conservation efforts, the Project will be designed to utilize NPW for all outdoor irrigation demands.
August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 5 of 57 To clarify, when the District was preparing the basis for future water demands within the District's service area in the BCVWD's 2020 UWMP, the District utilized the potable water demands from the November 2020 BP DRAFT WSA. This draft version of the Project's WSA identified the potable water demand as 221 EDUs as shown in Table 3-7 in the BCVWD's 2020 UWMP.
Because the Project's updated land use plan has a potable water demand of 204.21 EDUs, the District's 2020 UWMP conservatively included the Project's anticipated potable water demands.
August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 6 of 57 Section 3.2 San Gorgonio Pass Water Agency 2015 UWMP
Section 3.2 shall be removed and replaced with the following and the section title shall be replaced with "San Gorgonio Pass Water Agency 2020 UWMP". This section has been updated to reflect the changes in both the BCVWD and the SGPWA 2020 UWMP.
The Beaumont Pointe Development is located within the service area of the San Gorgonio Pass Water Agency (SGPWA or Pass Agency). BCVWD provided data to SGPWA on BCVWD's projected demands so the SGPWA could prepare their UWMP. Because the California Department of Water Resources (DWR) required the imported water suppliers to submit their UWMPs earlier than the retail agencies, BCVWD made some preliminary estimates of their demand over the 20 -year projection period and provided the projections to SGPWA. These preliminary estimates deviated slightly from the actual demands in BCVWD's 2020 UWMP. Since the BP Project site was included in the demands in BCVWD's 2020 UWMP, it is considered to be included in the 2020 SGPWA UWMP, adopted by SGPWA Board of Directors on June 21s1, 2021.
Table 3-1 below is taken from Table 3-16 in the SGPWA 2020 UWMP.

In Chapter 1 of the SGPWA's 2020 UWMP, the UWMP stated the following. "It is important to note that this UWMP [SGPWA 2020 UWMP] has been completed to address regional resource management and does not address the particular conditions of any specific retail water agency or entity within the SGPWA service area. The retail urban water suppliers within SGPWA service area are preparing their own separate UWMPs where required, though SGPWA has facilitated coordination among the retailers to assure consistency."
August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 7 of 57 BCVWD recognizes and acknowledges the disclaimer statement within the 2020 Urban Water Management Plan prepared by the SGPWA related to regional planning. While the UWMP prepared by the SGPWA "...does not address the particular conditions of any specific retail water agency..." BCVWD relies upon the policies and practices of the SGPWA as a foundation for regional water supply solutions. In other words, while the SGPWA's regional planning document does not address local water conditions, BCVWD does rely upon the policies of the SGPWA to provide comprehensive regional solutions related to the use of imported water in the SGPWA area. As an example of the policies and practices adopted by the SGPWA and relied upon by BCVWD include, but are not limited, to the following:
• San Gorgonio Pass Water Agency, Ordinance No. 8, An Ordinance Establishing Rules and Regulations for SGPWA Water Service, February 7, 2005; • San Gorgonio Pass Water Agency Strategic Plan, May 2012; • San Gorgonio Pass Water Agency, Resolution No. 2014-02, A Resolution of the San Gorgonio Pass Water Agency Establishing a Policy for Meeting Future Water Demands, February 18, 2014;
• San Gorgonio Pass Water Agency, Ordinance No. 10, Ordinance Establishing Water Shortage Plan, July 21, 2014;
• San Gorgonio Pass Water Agency, Resolution No. 2015-05, Resolution of the Board of Directors of the San Gorgonio Pass Water Agency to Adopt Facility Capacity Fees for Facilities and Water, July 27, 2015;
• San Gorgonio Pass Water Agency, State of the Supply PowerPoint Presentation, September 30, 2016;
• San Gorgonio Pass Water Agency, Ordinance No. 13, An Ordinance Amending Rules and Regulations Regarding Authorization for Service, June 5, 2017.
Section 3.3 BCVWD's 2015 UWMP
Section 3.3 shall be revised as shown in red below. This Section has been updated to note the minor differences between the projections in the BCVWD's 2020 UWMP and the projections provided to SGPWA for their 2020 UWMP. Additionally, the section title shall be revised to state `BCVWD's 2020 UWMP".
There were some minor differences between the projections in BCVWD's 2020 UWMP and the projections provided to SGPWA for their 2020 UWMP. These differences stemmed from the need for BCVWD to provide preliminary demand projections early on so the SGPWA could meet their prescribed deadline.
BCVWD's demands for imported water are presented in BCVWD's 2020 UWMP (Table 6-24) and are repeated in Table 3-2 below. Table 3-2 shows the actual imported water demand to meet the potable water demand plus the banking water demand to ensure drought -proofing of future development. If imported water is not available in a given year, no banking will occur. But when imported water is available, any deficiencies from previous years would be "carried over" and "made up." As can be seen, there is a slight difference between the demands in Table 3-2 versus those shown above in Table 3-1.
