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.

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.

16 13
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 Model16

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.

Beaumont Pointe
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.

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.

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 21st, 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, 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.

Section 4.1 — Project Description
The last paragraph in Section 4.1 shall be revised as shown in red below. These revisions will clarify the use of utilizing non -potable water for all outdoor irrigation demands.

The project is required to adhere to the landscaping standards in the "Guide to California Friendly Landscaping", the City of Beaumont's, and Riverside County Landscaping Ordinances which requires water efficient landscaping. Pursuant to BCVWD requirements, and as part of ongoing water conservation efforts, all outdoor irrigation demands shall utilize non -potable water, and recycled water produced by the City of Beaumont and distributed by BCVWD as it becomes available.

Section 4.2 — Estimated Water Demand - Tables 4-2 Note 5 and 6 Notes 5 and 6 under Table 4-2 in the WSA shall be revised as shown in red below. These revisions clarify the potable water demand for the Project's latest land use plan, and the use of non -potable water for all outdoor irrigation demands.

[5] Represents demands that be served by non -domestic water sources.

Section 4.2 — Estimated Water Demand
The last paragraph shall be revised as shown in below. These revisions clarify the reduced potable water demand shown in the BCVWD 2020 UWMP and the use of non -potable water for all outdoor irrigation demands.

Table 4-2 and 4-3 calculate the total estimated water demand at Beaumont Pointe Development buildout of 175,584 gpd, or 196.70 AFY. Based on BCVWD equivalent dwelling unit usage of

0.546 AFY per equivalent dwelling unit, this equates to 360.26 EDUs (196.70 AFY). Of the total water demand, the potable water demand is estimated to be 204.21 EDUs (111.50 AFY) and the non -potable water demand for outdoor irrigation is estimated to be 85.20 AFY, equivalent to 156.04 EDUs.

Section 5.1 — Overview of BCVWD's Water System and Operation — Table 5-1 Table 5-1 shall be revised as shown in below. These revisions update the potable and non -potable water connections, average and maximum day demands to reflect the values listed in the BCVWD 2020 UWMP. Please note that the BCVWD 2020 UWMP does not include the total water pumped for 2020 and therefore this row was removed from Table 5-1.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 10 of 57 Section 5.2 — Potable Water System
Section 5.2 shall be removed and replaced with the potable water system overview provided in the District's 2020 UWMP.

BCVWD's potable water system is supplied by wells in Little San Gorgonio Creek (Edgar Canyon) and the Beaumont Basin (sometimes called the Beaumont Storage Unit or the Beaumont Management Zone). The District has a total of 24 wells (1 well is a standby). One of the wells, Well 26, can pump into either the potable water or the non -potable water system. Currently, it is pumping into the non -potable water system.

The Beaumont Basin is adjudicated and managed by the Beaumont Basin Watermaster. BCVWD augments its groundwater supply with imported State Project Water from the SGPWA which is recharged at BCVWD's recharge facility at the intersection of Brookside Avenue and Beaumont Avenue. The Beaumont Basin Adjudication requires that the extracted amount of water from the Basin must be replaced.

Wells in Edgar Canyon have limited yield, particularly in dry years, and take water from shallow alluvial and fractured bedrock aquifers. Wells in the Beaumont Basin are large capacity and pump from deep aquifers — some as deep as 1,500 ft below the ground surface. The Edgar Canyon wells are very inexpensive to operate and are the preferred source due to there being no replenishment requirement like the Beaumont Basin; however, those wells are not able to meet the current average day demand. The Edgar Canyon wells pump to a gravity transmission main that extends the full length of the District -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, is transferred to lower pressure zones serving the City of Beaumont. The Edgar Canyon Wells provide about 15 to 20 percent of the total annual supply; the rest is pumped from wells in the Beaumont Basin supplemented by recharged imported water.

BCVWD has two active stream diversion locations within Little San Gorgonio Creek (Edgar Canyon) that are in the State Water Resources Control Board, Division of Water Rights database (S014351, S014352). The diversions have pre -1914 recorded water rights amounting to 3,000 miner's inch hours (MIH) or approximately 45,000 AFY of right for diversion of water for domestic and irrigation uses. These date back to the early history of the District. However, the District 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. At the present time, the District currently diverts streamflow in Edgar Canyon to a series of percolation ponds which recharge the shallow wells in Edgar Canyon. This water is then extracted for domestic purposes.

BCVWD's total well capacity (Edgar Canyon and Beaumont Basin) is about 27.5 mgd with the largest well out of service, which is greater than the current 21.6 mgd maximum day demand (2020). The District has 11 pressure zones and 14 reservoirs (tanks) ranging in size from 0.5 MG to 5 MG. Total storage is approximately 22 MG —just over two average days or just over one maximum day. 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 transmission system in the main pressure zones is comprised of 24 -in diameter pipelines (there are some 30 -in diameter pipelines at some reservoirs). The bulk of the transmission system is ductile iron pipe with cement mortar lining and was installed in the last 10 to 15 years.

There are a number of small distribution lines (4 -in and smaller) that are gradually being replaced over time with minimum 8 -in diameter ductile iron pipe. All developments, since the early 1980s, have installed mortar lined, ductile iron pipe. The distribution system is capable of providing over 4,000 gallons per minute (gpm) fire flow in the industrial/commercial areas of the service area.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 11 of 57 Section 5.3 — Imported Water and Recharge Facilities
Section 5.3 shall be removed and replaced with the Imported Water and Recharge Facilities overview provided in the District's 2020 UWMP.

Around 2001, BCVWD began investigating an 80 -acre site on the east side of Beaumont Avenue between Brookside Avenue and Cherry Valley Boulevard as a location for a facility to recharge captured storm flow and imported water. After extensive hydrogeologic investigations, including pilot testing, the District eventually purchased the site (known as the Oda Property) and developed Phase 1 of the recharge facility on the westerly half of the site. The Phase 1 facilities were completed and went online in late summer 2006. Phase 2 of the recharge facility was completed in 2014. The 80 -acre site has excellent recharge capabilities with long-term percolation rates around 7 to 10 acre-ft/acre/day, with proper maintenance.

The District completed construction of a 24 -in pipeline from the SGPWA turnout on East Branch Extension (EBX) of the State Water Project to the District's recharge facilities in 2006. A metering station was installed at the turnout at Noble Creek and Vineland Avenue and BCVWD began taking imported water deliveries from SGPWA for recharge in September of 2006. In 2019, the EBX facility was expanded to allow for additional imported water capacity. Since its operation in 2006 through the end of 2020, nearly 108,900 acre -ft (about 35.5 billion gallons) of imported water have been recharged. As of the end of 2020, BCVWD has 39,750 acre -ft "banked" in the Beaumont Basin; this is more than a three-year supply.

The District is also currently working with Riverside County Flood Control and Water Conservation District to complete the MDP Line 16 Project, which will allow the District to capture and recharge stormwater at the Phase 2 recharge facilities. The expected volume of stormwater able to be recharged is approximately 250 AFY. Construction is expected to begin in 2021 and be completed by fall 2022.

Section 5.4— Non -potable (Recycled) Water System
Section 5.4 shall be removed and replaced with the Non -potable (Recycled) Water System overview provided in the District's 2020 UWMP. The purpose of including this section will be to identify the current and future operating NPW systems and their source of NPW.

Currently, BCVWD has over 40 miles of non -potable water transmission and distribution pipelines (6 -in and larger) in -place. This construction has occurred since about 2002. A 24 -in diameter ductile iron pipeline forms a loop around the City of Beaumont. The system includes a 2 million gallon recycled (non -potable) water reservoir which provides gravity storage and pressurization for the system. The 2 MG non -potable water reservoir is configured to receive potable water or untreated State Project Water (SPW) through air gap connections. The non -potable water system can have a blend of recycled water, imported water, non -potable groundwater, and potable water.

The 2 MG reservoir is located at the District's groundwater recharge facility at Beaumont Avenue between Brookside Avenue and Cherry Valley Boulevard. There are about 300 existing landscape connections to the recycled water system receiving about 1,600 acre -ft of water based on 2020 water meter records (in 2019, the non -potable water demand was 1,540 acre -ft). The effects of increased development in the District's service area impacted the non -potable system too.

A large part of the non -potable water system is currently supplied from Well 26 and supplemented with potable water which is introduced into the 2 MG non -potable water tank through an air gap connection. The non -potable water system in the Tournament Hills and Fairway Canyon area is currently supplied with potable water through temporary interconnections between the potable and non -potable water system.

BCVWD is currently working with the City of Beaumont to secure recycled water for use in the non -potable water system. As of the end of 2020, the City is nearing the completion of the

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 12 of 57 expansion and upgrade of its existing wastewater treatment facility to bring it to 6 MGD capacity and will be installing a new membrane bioreactor (MBR) treatment unit followed by reverse osmosis membrane treatment. A brine line from the treatment plant to the Inland Empire Brine Line (IEBL) in San Bernardino was constructed in 2020. Upon the availability of recycled water from the City, the non -potable system will be completely severed from the potable system.

A memorandum of understanding 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 an agreement for purchase of recycled water through an ad -hoc committee consisting of City Council members and BCVWD Board Members.

The Regional Water Quality Control Board (RWQCB) has ordered the City to be in compliance with the maximum benefit provisions, which include providing recycled water for beneficial use, by November 30, 2020. Construction completion has been delayed due to wet weather and the Covid-19 virus shutdown.

When the demand for recycled water for landscape irrigation is less than the supply available (winter months), BCVWD may ultimately recharge surplus recycled water at BCVWD's groundwater recharge facility or some alternative facility with appropriate treatment and permits.

Recycled water use and recharge is permitted by the Beaumont Basin Adjudication.

Section 6.1 Regional Water Supply Demand Spreadsheet Models As required by SB610, a Project's WSA must identify other public water systems that receive water from the same source as the public water system. Since BCVWD relies heavily on imported water from the SGPWA, updated numbers from the other regional retail agencies and their estimated current and future water demands were listed in the original Project's WSA. Therefore, Table 3-16 from the 2020 SGPWA UWMP is shown below and is intended to update the water supply demands for the different SGPWA service areas described in Section 6.1.1 through Section 6.1.3 in the original WSA.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 13 of 57 Section 6.1.3.1 — City of Beaumont Development and Section 6.1.3.2 Cherry Valley Growth and Development.

Section 6.1.3.1 and 6.1.3.2 in the Beaumont Pointe Development WSA listed the major development projects in the BCVWD service area and their estimated existing and future EDUs. This allowed for the Supply -Demand Model for BCVWD to be projected for the next 20 years. The following is intended to replace Sections 6.1.3.1 and 6.1.3.2 in the Project's WSA and is taken from the District's updated 2020 UWMP.

Historic and current populations for the District's service area were extracted from the District's 2015 UWMP are presented in Table 6-2 (Table 3-4 from the BCVWD 2020 UWMP) as the District is still awaiting the results of the 2020 census. There were some adjustments to account for the latest census data. The data in Table 6-2 came from several sources:
• 1980 and 1990 populations and household information — U.S. Census Bureau, 2000 Census of Population and Housing, Population and Housing Unit Counts, PHC-3-6, California, Washington D.C., 2003. This data was used for the City of Beaumont. Data for Cherry Valley for this period was estimated.
• 2000, and 2010, 2015, and 2019 population and household information — U.S. Census Bureau American Fact Finder for Beaumont, CA and Cherry Valley CDP12, CA. • 2020 Population- Estimated for Cherry Valley based on historic growth from 2018.

Estimate for the City of Beaumont based on housing completions from City Planning Department, Major Project Status for period 2010 through 2019, and District staff discussions with various developers regarding construction progress for major projects in the District's service area (ongoing projects discussed herein).

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 14 of 57 Figure 6-1 shows the population growth in the City of Beaumont and Cherry Valley from 1980 to 2020. The population after 2015 was estimated as described for Table 6-2.

The data in Table 6-2 and Figure 6-1 shows a very rapid growth for the City of Beaumont between the years 2000 to 2020. Nearly 2/3 of this growth occurred between 2000 and 2010 based on building permits issued by the City of Beaumont. The high rate of growth decreased after 2010 following the economic turndown in the U.S. and California in 2008 which continued for several years. The rate of growth in the District's service area has increased again after 2015 after the start of the economic recovery. The population in Cherry Valley remained relatively constant since 1990. The community of Cherry Valley did not experience the same growth spurt that occurred in the City of Beaumont and other areas in Western Riverside County. 74, 000

Figure 6-1 shows the number of single-family home building permits issued in the City of Beaumont for the year 2010 through 2019 (February 2020). BCVWD projects that approximately 500 single family home building permits were issues in 2020. Although not shown in Figure 6-1, the permits started picking up in 1999-2000 and reached their peak in 2005 with nearly 2,300 new home permits issued for that year. The number of permits for new homes declined to a low of 169 in 2011. Over the last 10 years (2011-2020), permit averaged 450 per years; over the last 5 years (2016-2020), permits averaged 541 per year. The 20 -year average has been 693 per year.

Future growth will likely be in the range of 350 to 650 permits per year, although some developers have project slightly higher amount in their build -out forecasts.

Figure 6-2: Growth in Beaumont as Shown by Single Family Home Building Permits BCVWD uses Equivalent Dwelling Units (EDUs) to project water demands, water supply needs, and estimated population growth in the service area. Review of the City of Beaumont's Major Project Status Report listed six projects that were currently under development (on -going construction). These are listed in Table 6-3 below. It appears there are about 3,155 EDUs in the current on -going projects yet to the constructed as of February 2021.

Table 6-4 presents a list of other projects in various stages of approval the City of Beaumont.

The total number EDUs is estimated to about 9,200.

The housing units yet to be constructed in Table 6-3 plus the EDUs in the other projects in Table 6-4 total about 12,400 EDUs in the City of Beaumont. This would result in an increase in population of about 35,000 people based on 3.28 people per EDU (average density for the City of Beaumont). This would bring the total Beaumont population to about 95,000. Based on the estimated build -out year for each project in Table 6-4, this population would not occur until after 2045.

Note:

1. Taken from Table 3-7 in the BCVWD 2020 UWMP
Prior "proposed" projects equivalent dwelling units within the BCVWD service area were estimated at 12,544 (Legacy Highlands WSA, June 2020). The Beaumont Pointe Development project site was previously planned with a land use density of 2,000 equivalent dwelling units (EDUs). The new Beaumont Pointe Development land use plan estimates a significantly reduced density of 360.26 EDUs, representing a reduced site density by 82 percent. 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 or approximately 156.04 EDUs.

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 6-4. 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.

1. Taken from Table 3-9 in the BCVWD 2020 UWMP
The growth in EDUs in Table 6-6 was the basis for projecting the water demand in the 2020 UWMP and is presented in future sections of this WSA addendum.

The BCVWD service area build -out or "saturation" population was determined using the City of Beaumont's Zoning Map and Table 3.2a from the City's General Plan (2020) to determine the total areas of the various zoning categories in the District's SOI. Actual GIS data was obtained from the City and integrated into the District's GIS system to determine the land uses within the District's SOI. The zoning designation includes a range of dwelling units/acre. Table 3.2 from the City's General Plan Update includes the estimated number of residential units per land use category.

A similar approach was used for Cherry Valley, only the data from Riverside County General Plan, Pass Area Land Use Plan was used. Again, the GIS data set was obtained from the County and integrated into the District's GIS system to determine the land use category areas within the District's SOI.

BCVWD believes the build -out population for the SOI will increase from that presented in the 2015 UWMP, but the increase is yet to be determined. Build -out will not occur until sometime after 2045. Build -out population is valuable to determine ultimate water demands and ultimate facility requirements.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 19 of 57 Section 6.1.3.3 — Supply Demand Model for BCVWD
Section 6.1.3.3 shall be removed and replaced with the following updates from the BCVWD 2020 UWMP.

As required by the SB610, the Project's WSA shall discuss the public water systems water supplies available during normal conditions for existing and future conditions in 5 year periods for 20 years. To update Section 6 and to provide a 20 -year outlook based on the BCVWD 2020 UWMP, the following is intended to replace Section 6.1.3.3 based on providing a 20 -year projection.

BCVWD's current and future water sources can be summarized in the Table below and as described below. As shown in the table above, the total BCVWD demand is less than the total available supply showing BCVWD will have sufficient water supplies for the Project under normal operating conditions.

Note:

1. Taken from Table 6-1 in the BCVWD 2020 UWMP
BCWD's source of supply consists of:
• Edgar Canyon (Little San Gorgonio Creek) Groundwater — BCVWD has long-term records on pumping. From 1957 to 2020, a period of 64 years, the average production from the Edgar Canyon Wells is 1,881 AFY. However, prior to 1983, the ability to utilize the water pumped from Edgar Canyon was limited due to a lack of sufficient conveyance capacity to deliver water from Edgar Canyon to Cherry Valley and Beaumont. In 1983,

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 20 of 57 the District installed the 14 -in Edgar Canyon Transmission Main which enabled larger quantities of water to be conveyed from Edgar Canyon to Cherry Valley and Beaumont.

From 1983 to 2020, a period of 38 years, the average amount pumped was 2,073 AFY.

This is far more indicative of Edgar Canyon's ability to produce water. As shown in Table 6-7 in the BCVWD 2020 UWMP the Edgar Canyon Wells produced about 10% of the District's annual demand (potable and non -potable) in 2020. • Beaumont Basin
o Overlier Potable and Non -Potable Water Forbearance — is credited to a water supplier by Watermaster for any potable and/or recycled water provided to an overlying party or an overlying party's land. The overlier forbears pumping the equivalent amount of water supplied and the appropriator then has the right to pump the volume of water forgone by the overlier. This is done through the Basin Watermaster who transfers forgone water to the appropriator's groundwater storage account on an annual basis.
o Reallocated Unused Overlier Pumping Rights — All of the "safe yield" from the Beaumont Basin is allocated to the overlying parties (overliers). Each overlier was given a share of the safe yield and was allowed to pump no more than five times that share in any five-year period. Most, if not all, of the overliers do not pump their entire share of the safe yield. The amount of groundwater not produced by an overlying party shall be available for allocation to appropriators in accordance with their percentage shares of unused safe yield stated in the Adjudication Exhibit C3. BCVWD's share is 42.51% of the unused overlier pumping rights. The Beaumont Basin Watermaster administers this reallocation and transfers the appropriate amounts into the appropriators' storage accounts on an annual basis.
o Return Flow Credits — Return flow is defined as the portion of water which is applied to the land which is not evaporated or evapo-transpired and which ultimately percolates (returns) to the groundwater table and which can be re - extracted for use. Return flows originate from irrigation of agricultural land and lawns and landscaped areas in rural and urban settings and from deep percolation of septic tank effluent in unsewered areas, e.g., Cherry Valley. In most adjudicated groundwater basins, credit is given to the supplier of water which is used on land overlying the groundwater basin and which percolates back or "returns" to the groundwater. Watermaster provided annual return flow estimates from various land uses in Table 3 of the Safe Yield Report and were used in estimating current and future return flow credits. • Storm Water — Stormwater capture plays a significant role in BCVWD's local water resources supply development. Diverted stormwater is/will be routed to percolation ponds capable of recharging the groundwater basins. The District currently has stormwater diversion located in the Upper and Middle of Edgar Canyon
o Potential Stormwater Capture Projects — The District has a number of potential stormwater capture projects as summarized in Table 6-8 with their potential estimated stormwater capture flows shown in Table 6-9.

Noble Creek flows could be desilted on property owned by 6CVWD (15.7 acres) along Noble Creek upstream of Noble 5t and west of Cherry Ave. Unfortunately, this area is not over the Beaumont Basin. but the property could be used for desilling basins with the desilled water released back into Noble Cr. and recaptured at a soft plug in the lined channel and diverted into the District's recharge site. Estimated Yield = 400 AFY.

Marshall Creek sio
Elm to 1-10
There is a significant amount of urban runoff from the developed area east of Beaumont Ave, between Oak Valley Parkway and Brookside Ave. which could be captured in the soft bottom of Marshall Creek using training dikes to prevent the water from going under the 1-10 bridge.

There is about 300 ac of urban drainage. Estimated Yield = 150 AFY.

Beaumont MDP
Lane 16
Approximately 517 acres of area could be Intercepted by a storm drain along Grand Ave. and conveyed to the District's Recharge facility. This water is relatively free of sediments and runoff is generated with even the slightest amount of rainfall_ Refer to Table 6-11 for estimates of stormwater capture.

Sundance Urban

• Non -Potable Groundwater
o Mouth of Edgar Canyon (Potential)— High nitrate groundwater located at the mouth of Edgar Canyon 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 Creek (Potential) — 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

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 22 of 57 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. • Recycled Water — The District is currently in the process of finalizing its Non -Potable Water Master Plan, which includes more current non -potable system facility requirements and recycled water supply projections. The non-potable/recycled water supply data provided in this WSA addendum are consistent with the District's 2020 UWMP. The non- potable/recycled water supply projections are considered draft as of the date of approval of this Addendum 1. Data from the BCVWD 2020 UWMP is used for consistency.

BCVWD is currently working with the City of Beaumont to distribute Title 22 recycled water produced at the City of Beaumont's Treatment Plant No. 1. Phase 1 of the City's wastewater treatment plant construction has been completed, increasing the rated capacity from 4 MGD to 6 MGD. Process upgrades include redundant coarse screens, a grit removal system, a flow equalization basin, a fine screen system, an activated sludge process coupled with a new MBR system followed by a partial RO, and a new UV disinfection system. The City submitted a Title 22 Recycled Water Engineering Report to the Santa Ana Regional Water Board in September 2019 and is awaiting formal comment. Another component to the treatment facility upgrades is the construction of a 12 -inch diameter gravity pipeline from the Beaumont WWTP to the nearest connection point in the Inland Empire Brine Line (IEBL) to dispose of the brine waste generated by the upgraded treatment facility. Construction of the brine line was completed around early 2020 and is approximately 23 miles long.

BCVWD continues to work with the City relative to recycled water. Historically, the City of Beaumont's effluent has experienced TDS concentrations of about 400 mg/L, which is an excess of the Regional Board's Maximum Benefit Water Quality Objectives for the Beaumont Basin. With the implementation of the reverse osmosis system, the recycle water from the City will be treated to a high-level and should have no issue in achieving the Maximum Benefit Water Quality Objectives.

Table 6-10 below lists the estimated recycled water produced, the recycled water that must be reserved for habitat mitigation (1.8 mgd), and the net amount of recycled water available for recycling. Please note that not all the wastewater can be recycled due to onsite recycled water demands and reject water from the reverse osmosis process.

1. The City of Beaumont population growth is less aggressive than shown in tables presented in Section 3 of the BCVWD 2020 UWMP to be conservative in the amount of recycled water available.

2. Table taken from Table 6-15 in the BCVWD 2020 UWMP.
• 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.

August 24Th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 24 of 57 For the normal year, there is more than enough supply to meet the demand and BCVWD can bank water in the Beaumont Basin, which will be needed during dry periods. As noted in Table 6-11 below, demand totals include BCVWD's need include banking imported water to ground water storage for drought proofing. Any additional supply available after all demands have been satisfied would be recharged and added to BCVWD's storage account.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 25 of 57 Section 7 SGPWA Available Imported Water
BCVWD relies on imported water from the SGPWA. In order to meet the requirements of SB610 of showing the current and future availability of the BCVWD water supplies, Section 7 of the original WSA is intended to be replaced with following which is essentially a summary of Section 3.1 from the 2020 SGPWA UWMP in order to describe the updated SGPWA Imported Water Supply Sources. 7 SGPWA Available Imported Water
In November of 1962, SGPWA entered a State Water Project water service contract (SWP Contract) with the State of California Department of Water Resources (DWR). The SWP Contract authorized DWR to deliver SWP water to SGPWA under certain terms and conditions.

SGPWA also acquires water supplies through contracts with other agencies and annual water transfers and exchanges. SGPWA annually acquires Yuba Accord water as well as water under the Nickel Agreement. SGPWA may also acquire water through an agreement with San Bernardino Valley Municipal Water District (SBVMWD) as well as annual transfers and exchanges with other SWP contractors. And, in the future, SGPWA will acquire water through the Sites Reservoir Agreement. All of these additional supplies, beyond SGPWA's SWP supply, are discussed in the following sections
SGPWA's delivery of supplemental water includes both delivery to water filtration facilities and groundwater recharge basins to assist with the management of groundwater in the SGPWA service area. Whether by direct delivery, in -lieu recharge, or direct recharge, the SGPWA plays a critical role in the local management of groundwater and surface water resources.

7.1 State Water Project Overview
The State Water Project (SWP) is the largest state -built, multi -purpose water project in the country. It was authorized by the California State Legislature in 1959, with the construction of most facilities completed by 1973. Today, the SWP includes 28 dams and reservoirs, 26 pumping and generating plants, and approximately 660 miles of aqueducts.

The primary water source for the SWP is the Feather River, a tributary of the Sacramento River.

The water flowing in the Feather River is captured by the SWP in Oroville dam and reservoir.

Storage released from Oroville Dam flows down natural river channels to the Sacramento -San Joaquin River Delta (Delta). While some SWP supplies are pumped from the northern Delta into the North Bay Aqueduct or diverted by SWP contractors upstream, the vast majority of SWP supplies are pumped from the southern Delta into the 444 -mile -long California Aqueduct. The California Aqueduct conveys water along the west side of the San Joaquin Valley to the Edmonston Pumping Plant, where water is pumped over the Tehachapi Mountains. From there the California Aqueduct divides into the East and West Branches. SGPWA takes its SWP deliveries from the East Branch, which was completed in 2003. Phase 2 of the East Branch Extension was completed in 2018 which increased the capacity of the supplemental water supplies and allowed the SGPWA to take the Agency's official maximum allotment of State Project Water.

SGPWA delivers its SWP supplies, along with other water supplies, to recharge local groundwater basins through transmission pipelines and recharge systems as well as some delivery to Yucaipa Valley Water District.

SGPWA is one of 29 water agencies that have a SWP Contract with DWR. Each SWP contractor's SWP Contract contains a "Table A Annual Amounts" (Table A) which lists the contracted maximum amount of water an agency may receive under its contract. Table A is also used in determining each contractor's share of the total SWP water supply DWR determines to be available each year. The total planned annual delivery capability of the SWP and the sum of all

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 26 of 57 contractors' maximum Table A amounts was originally 4.23 million acre-feet. The initial SWP storage and conveyance facilities were designed to meet contractors' water demands with the construction of additional storage facilities planned as demands increased. However, few additional SWP storage facilities have been constructed since the early 1970s and a portion of the original conveyance design was never completed. SWP conveyance facilities were generally designed and have been constructed to deliver Table A to all contractors. The maximum Table A of all SWP contractors now totals about 4.133 million AF. SGPWA manages its SWP supplies to maximize the availability of these supplies to its retail customers. In this way, SGPWA seeks to optimally manage its Table A wet year supplies, acquire additional SWP supplies through Article 21 conditions (SWP surplus conditions), access Advanced Table A supplies, and potentially exchange Table A supplies with other SWP contractors. All of these actions improve the long- term reliability of Table A supplies.

7.1.1 Table A Allocations
SGPWA's Table A Annual Amount is 17,300 acre-feet per year up through the 2045 UWMP planning horizon. SGPWA's Table A represents a maximum contract amount that could be available each year assuming that the SWP could deliver 100% contract supplies to all SWP contractors. The last 100% allocation year occurred in 2006. SGPWA's SWP Contract has numerous components that allow SGPWA to manage and control the annually available SWP water supplies.

More often than not, actual SWP allocations are less than 100% SGPWA's Table A Annual Amount. Annual SWP percentage Table A allocations fluctuate based upon hydrology, water storage, and regulatory criteria in the Delta. Table 7-1 below shows the SGPWA Table A Annual Amount from 2010 through 2020, the SWP allocation percentage, and the final available Table A allocation from 2010-2020. During this period, the SGPWA received on average 8,335 acre-feet, or about 48% of the Table A contract amount. It is important to recognize that this period included a significant and recent drought event.

DWR has projected that it is less likely that 100% allocation years will occur on a regular basis in the future. In August 2020, DWR finalized the "2019 SWP Delivery Capability Report" (DCR) that outlined the probable future water supply allocations for the SWP system. The DCR showed variations in future Table A deliveries based upon hydrological and regulatory conditions. These

1. Taken from Table 3-2 in the 2020 SGPWA UWMP
As shown in Table 7-2, DWR's long-term average reliability shows a downward trend from 62% in the 2017 SWP DCR to 58% in the 2019 DCR. DWR attributes this downward trend to climatological and hydrological factors that impact precipitation patterns and snowfall accumulation above its main SWP facility, Lake Oroville. In this way, SGPWA characterizes its average normal year SWP water supply through 2045 as 58% of its Table A Annual Amount in accordance with the DCR. Thus, from 2025 through 2045, SGPWA's projected Table A final available allocation will be 58% of 17,300 acre-feet or 10,034 acre-feet per year. Importantly, SGPWA anticipates years where its Table A Allocation exceeds the average normal year delivery of 58%. In these years, SGPWA will capture and store the surplus water assets.

The single dry year characterization and five consecutive dry year characterization for the SWP supplies are also an important consideration in SGPWA's UWMP. The 2017 and 2019 DCR represent the single driest year as 1977 with an 8% SWP allocation estimate in 2017 DCR and a 7% SWP allocation estimate in 2019 DCR. The single lowest historical SWP allocation occurred in 2014 at 5%, and this 5% allocation is also representative of the 2021 Table A Allocation. As such, to be conservative in its projections, SGPWA will use 5% of 17,300 acre-feet or 865 acre- feet per year as the single dry year allocation through 2045 as depicted in Table 7-3.

The 2019 DCR also identifies various drought periods for purposes of characterizing SWP allocation percentages that would accompany those drought periods. The averaging of the allocations over the course of the drought period is not representative of SGPWA drought planning purposes. SGPWA will use the following drought characterization for its short-term and long-term planning: year 1 at 35%; year 2 at 5%; year 3 at 5%; year 4 at 20%; and year 5 at 35%. SGPWA examined the historical record and determined that there was no representative five consecutive year historical SWP delivery dry period that adequately reflects a potential future

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 28 of 57 five-year critical drought condition that could drastically reduce SWP supply deliveries for SGPWA's service area. As such, taking a more conservative planning approach, SGPWA created a more restrictive dry year characterization that adequately represents a critical drought over five consecutive years. In this dry year modeled sequence, two consecutive critically dry years are bounded by Table A allocations that are reflected in the recent historical record. Table 3-4 shows the normal year, single dry year, and five consecutive dry years planned SWP Table A Allocation for San Gorgonio Pass Water Agency through 2045.

7.1.2. Table A Carryover Water
SGPWA's SWP Contract allows it to forego use of its allocated SWP Table A supply and retain a portion of that allocated supply in storage for future use. This retained supply is termed "Carryover" and is governed under Article 56 of SGPWA's SWP contract. Carryover water is water that is released from Oroville dam and reservoir, re -diverted at the Delta, and then stored in San Luis Reservoir — an off -stream reservoir located just outside the City of Santa Nella at the junction of Interstate 5 and California State Highway 152. San Luis Reservoir is jointly owned and operated by the state and federal governments and all SWP contractors may use the storage facility to manage Carryover water supplies. In short, the San Luis Reservoir receives, regulates, and stores exported water derived from the State Water Project and Federal Central Valley Project.

The amount of water that SGPWA may carryover in any given year is subject to a set of rules that implicate all SWP contractors throughout California. In brief, SGPWA delivers its Table A supplies to Carryover in San Luis Reservoir with an expectation that it will be able to divert all or a portion of these supplies in a subsequent year. In the event that water supplies are abundant, San Luis Reservoir may "spill." When San Luis Reservoir reaches a "spill" stage, DWR releases SGPWA's Carryover in accordance with the aforementioned rules as they apply in the context of all entities with stored water in San Luis Reservoir. Nevertheless, over the last 10 years SGPWA has retained a portion of its Table A Allocation as Carryover even in the driest years and continues to maintain a Carryover balance. Table 7-5 shows SGPWA's Carryover balance from 2010 through 2020.

Y)
The Carryover supplies noted in Table 7-5 combine a number of water management factors that impact SGPWA's overall water supply availability. For example, where SGPWA is able to acquire additional water assets in normal and wet year types, SGPWA may carryover SWP supplies to water shortage years for use. Moreover, where SGPWA may acquire alternative supplies through transfers and exchanges, even in the driest years, the Agency may then manage its supply portfolio to preserve Carryover supplies for later use. For instance, in 2015, SGPWA stored 954 acre-feet of water supplies as Carryover when SWP allocations were at the lowest historical allocation on record — five percent (5%) — in the 2014 water year (see Table 7-1).

Similarly, in 2015 — a 20% allocation year — SGPWA was able to carryover 936 acre-feet of water into the 2016 water year by acquiring alternative supplies and flexibly managing regional supplies in coordination with the retail agencies. SGPWA's management actions coordinated the Agency's available water supply portfolio in these years with the regional retail agencies water supply portfolios and water conservation efforts in order to preserve SWP supplies for future uses.

SGPWA will have access to its Table A Carryover supplies in future years based upon the hydrological and regulatory conditions. The Table A Carryover supplies result from a number of variables that are tied to the SWP Table A annual percent allocation, operations in San Luis Reservoir, and water supply management by SGPWA throughout its service area. In wet years, SGPWA carries over substantial supplies that are considered in the annual carryover numbers.

Accordingly, water years 2013 through 2017 above are representative of a five-year Carryover supply availability for SGPWA — and include 2014 and 2015 two of the driest years on record.

Furthermore, SGPWA conservatively estimates future Carryover supplies in a normal year to be approximately 5,200 acre-feet similar to 2013, 2014, and 2018 and carryover in a single dry year to be just over 900 acre-feet like 2015 and 2016. These supplies are estimated based upon typical SWP management in a normal year in context of SGPWA's total water supply portfolio.

The future normal year Carryover supply represents approximately half of SGPWA's normal year carryover number as noted in Table 7-5 but other years represent Carryover supplies that may result from additional SGPWA multi -year management actions that allow Carryover supplies to be available in these year types. Table 7-6 shows the Carryover supplies through 2025 and Table 7-7 shows the representative Table A Carryover supplies through 2045

7.1.3 Delta Conveyance Project Future SWP Increment
The Delta Conveyance Project, if implemented, would increase the future reliability of SGPWA water supplies derived from the SWP. Consistent with Executive Order N-10-19, in early 2019, the state announced a new single tunnel project, which proposed a set of new diversion intakes along Sacramento River in the north Delta for SWP. In 2019, the California Department of Water Resources (DWR) initiated planning and environmental review for a single tunnel Delta Conveyance Project (DCP) to protect the reliability of State Water Project (SWP) supplies from the effects of climate change and seismic events, among other risks. DWR's current schedule for the DCP environmental planning and permitting extends through the end of 2024. DCP will potentially be operational no later than 2040 following extensive planning, permitting, and construction.

SGPWA anticipates that the DCP will increase access to water assets by providing conveyance opportunities that are currently unavailable. SGPWA recently increased its investment in the DCP from 1.22% to 2% of project capacity in order to improve future conveyance actions related to its water asset portfolio. As such, the DCP investment should provide better access to SWP supplies in normal and wet years as well as opportunities to deliver alternative planned supplies as they become available to SGPWA.

7.2 SGPWA Additional Imported Water Supplies
SGPWA has numerous other current and future water assets besides its Table A Annual Amount and Table A carryover supplies. These supplies are derived from the following items: Yuba

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 31 of 57 Accord, Nickel Agreement, San Bernardino Valley Municipal Water District Agreement, and Sites Reservoir Agreement. These additional water sources are more fully described below.

7.2.1. Yuba Accord Water
In 2008, SGPWA entered into the Yuba Accord Agreement and has amended the agreement several times through 2014. The Yuba Accord Agreement allows SGPWA to purchase water from Yuba County Water Agency through its contractual arrangement with DWR that permits 21 SWP contractors (including SGPWA) and the San Luis and Delta -Mendota Water Authority regular access to the supply. Yuba Accord water comes from the Yuba River, located north of the Delta, and the water purchased under this agreement is subject to losses associated with transporting it to SGPWA's service area. While the amount of this water varies each year depending on hydrologic conditions, the Agency anticipates receiving an average future amount of approximately 300 AFY. The Agency recently signed an extension to this agreement allowing it to purchase this water well into the future. Table 7-8 shows the last five years of Yuba Accord water supplies coming to SGPWA. Table 7-9 shows the normal, single dry, and five consecutive dry year water supplies available under the Yuba Accord.

7.2.3. San Bernardino Valley Municipal Water District Agreement SGPWA entered the Surplus Water Sale Agreement with San Bernardino Valley Municipal Water District Surplus Water Sale Agreement (SBVMWD Agreement) in June of 2018. SBVMWD is a SWP contractor that holds an entitlement to 102,600 acre-feet under its Table A Annual Amount in its 1960 SWP contract. The SBVMWD Agreement entitles SGPWA to purchase up to 5,000 acre-feet of SWP entitlement each year with SBMVWD's express concurrence. The SBVMWD Agreement expires on December 31, 2032, and there is no right of renewal. Nevertheless, SGPWA anticipates renewing this contract. The amount of water available under the contract varies each year and is subject to the "sole discretion" of SBVMWD whether the water will be made available for SGPWA to purchase. The water supply under this agreement may be available depending upon SBVMWD's supply availability determination. The SGPWA is not incorporating this potential supply into its water supply reliability determinations for all year types but considers the supply a component of its available transfer and exchange supplies and, when acquired, may be incorporated into its groundwater storage facilities.

Sites Reservoir is a proposed new 1,500,000 acre-feet off -stream storage reservoir in northern California near Maxwell. Sacramento River flows will be diverted during excess flow periods and stored in the off -stream reservoir and released for use in the drier periods. Sites Reservoir is expected to provide water supply, environmental, flood, and recreational benefits. The proponents of Sites Reservoir include 30 entities including several individual SWP Public Water Agencies (PWAs). Sites Reservoir is expected to provide approximately 240 TAF of additional deliveries on average to participating agencies under existing conditions. Sites Reservoir is currently undergoing environmental planning and permitting. Full operations of the Sites Reservoir are estimated to start by 2029 following environmental planning, permitting, and construction. Sites was conditionally awarded $816 million from the California Water Commission for ecosystem, recreation, and flood control benefits under Proposition 1. Reclamation has also invested in Sites Reservoir and has allocated $13.7 million in 2021 for the project. Both SGPWA and Beaumont Cherry Valley Water District have purchased shares in Sites Reservoir, 10,000 shares and 4,000 shares respectively, that would augment supplies in the San Gorgonio Pass Water Agency service area. Table 7-12 shows the future availability of Sites Reservoir water in the SGPWA's service area and incorporates both the SGPWA and Beaumont Cherry Valley potential supplies. Other stakeholders with investments in Sites Reservoir have accounted for available supplies in 2035 as well.

7.2.5. Water Transfers and Exchanges
SGPWA also engages in water transfers and exchanges involving its SWP assets and other contractors' SWP water assets. Historically, SGPWA has both received and delivered water through these transfers and exchanges with various agencies throughout California. These transfers are essentially spot market transfers where short-term opportunities are identified and then actions taken for acquisition. These transfers help support management of SGPWA's and the retail agencies' water supply portfolios. Future SGPWA transfers and exchanges depend upon the allocations available to SGPWA and other water purveyors. As noted in Section 7.2.1., SGPWA has regularly acquired Yuba Accord water through its transfer and exchange activities.

In addition, the State Water Contractors collectively develop annual water transfer and exchange programs to develop transferable supplies and negotiate transfer terms. SGPWA regularly participates in SWC's transfer programs. SGPWA seeks to augment potential opportunities for exchanges and transfers with SWP contractors and alternative transfer opportunities like the SWC annual transfer program. Table 7-13 shows the planned future SWP and other water transfer opportunities that could be available for SGPWA.

7.3. Summary of Available Imported Water Supplies
As shown in Figure 7-1, SGPWA has reliable water supplies through the 2045 planning horizon.

SGPWA has assessed the available SWP supplies, imported supplies, and locally available managed water supplies to assess regional water supply reliability through this planning horizon.

In addition, SGPWA engages in annual water transfers and exchanges and stores water both within SGPWA's service area boundaries and outside its boundaries to address variable water conditions. Together, these supplies make up SGPWA's regional water asset portfolio that is actively managed by coordinated actions between SGPWA and the regional retail agencies to ensure long-term reliability.

SGPWA also coordinates management of its water supplies with the retail agencies to address projected dry conditions. Specifically, SGPWA and the retail agencies capture and store surplus imported water in normal and wet years in order to use the stored water assets to meet regional demands in dry years. Moreover, the retail agencies rely upon locally managed water supplies, including native groundwater, recycled supplies, surface water assets, and return flows, to meet their annual demands. These actions stabilize annual fluctuations in recurring imported supplies that may not meet regional demands under certain dry conditions. Figure 7-2 shows a water reliability assessment for a drought lasting five consecutive years where the retail agencies in SGPWA service area use stored water and regionally managed supplies to offset fluctuations in its SWP supplies. In summary, SGPWA's diverse surface water supply portfolio, combined with its coordinated management of regionally managed surface and groundwater resources with retail purveyors, provide stable and reliable water supplies to meet SGPWA's current and 2045 future water demands in its service area.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 36 of 57 Section 8 Water Supply and Demand for BCVWD
As shown in the updated Sections 6 and 7 above, BCVWD has sufficient supply and imported water to meet demands beyond 2045 under average demand and supply conditions (see specifically updates to Section 6.1.3.3.). Therefore, no amendments are required for this section.

Section 9 Water Supply Single and Multiple Dry Period Analysis As shown in the updated Sections 6 and 7 above, BCVWD has sufficient supply and imported water from SGPWA to meet the District's water supply requirements beyond 2045 under normal supply conditions.

As required by SB610, the Project's WSA must describe the reliability of BCVWD's water supplies during dry years. The following is intended to summarize the water supply reliability and drought risk assessment presented in Section 7 of the BCVWD 2020 UWMP for the purposes of replacing Section 9 in the Project's WSA.

Section 9 — Water Supply Reliability and Drought Risk Assessment Section 9.1 Constraints on Water Sources
A detailed description of BCVWD's current and future water sources are described previously in Section 6 of this WSA. Table 9-1, below shows a summary of BCVWD's current and future water sources and identifies the factors that affect the specific source's consistency of supply. Climate affects the amount of water available from most of the sources; there are some legal constraints on the Beaumont Groundwater Basin Source due to the Adjudication and contractual and environmental constraints on the imported State Project Water.

The District relies on groundwater banking within the Beaumont Basin during wet periods to supply demands during specified dry periods. Complementing the large storage capacity is the fact that percolation and recharge occur at relatively high rates making it very easy to "bank" water in the Beaumont Basin. Figure 9-1 below shows the amount of water BCVWD has accumulated in its storage account since 2003. Please note that imported water began to be spread in 2006.

Figure 9-1 — BCVWD's Beaumont Basin Storage Amount
Notes

1. Taken from Figure 7-1 in the BCVWD 2020 UWMP
With the ability to bank water and the large "underground" reservoir, BCVWD and its neighboring agencies can withstand extended periods of drought without severe restrictions. At the end of 2020, for example, BCVWD had 39,750 AF in storage. This amount in BCVWD's storage account has seen an increase of about 14,182 AF since 2015. BCVWD can store up to 80,000 AF in the Beaumont Basin managed by the Watermaster.

In Table 9-2 below (Table 6-24 in the 2020 BCVWD UWMP) a quantity of BCVWD-purchased imported water was identified as "From SGPWA for Banking." This varied from 1,000 AFY to 1,500 AFY and is over and above the amount of imported water needed to meet demands. The purpose of this "banking water" is to build up BCVWD's Beaumont Basin Groundwater Storage Account to be used as reserve for drought periods when adequate SPW is not available.

SGPWA is to supply the imported water requested in Table 9-2 below to meet BCVWD's needs plus the anticipated SPW for banking. If, in any year(s), either of these quantities cannot be supplied for any reason, the accumulated shortfall is expected to be delivered to BCVWD by SGPWA as soon as possible once imported water is available. In this way, BCVWD will be able to keep adequate water in storage for current (2020) needs and accommodate growth in BCVWD's service area. BCVWD anticipates banking around 28,500 AF of water over the next 25 years, which would bring BCVWD's storage account to about 68,250 AF. This is over 3 years of SPW requirements to meet 2045 demands with no SPW for over 3.5 years. The following subsections quantify the variability in BCVWD's water sources.

Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 40 of 57 Section 9.2 Regional Supply Reliability
BCVWD has a very diverse water portfolio that allows it to maintain a reliable water supply to its current and future customers. The existing sources include:
• Unadjudicated groundwater from the Little San Gorgonio Creek (Edgar Canyon) • Adjudicated groundwater from the Beaumont Basin
• Stormwater capture in Edgar Canyon (Little San Gorgonio Creek) and recharge in percolation ponds in Upper and Middle Canyon and at the Canyon mount in recently added desilting and recharge basins.
• Non -potable groundwater supplying the existing non -potable water system • Imported State Project Water from SGPWA
• AVEK-Nickel Water leased through SGPWA
• Yuba Accord water purchased through SGPWA
Potential Future Sources include the following and were described in Section 6.1.3.3 in this WSA Addendum.
• Recycled water from the City of Beaumont for landscape irrigation and with advanced treatment for indirect potable reuse (groundwater recharge). • Improved recharge of captured urban runoff from Sundance development • Non -potable groundwater from the mouth of Edgar Canyon • Non -potable groundwater from San Timoteo Creek
• Stormwater capture and recharge via the MDP Line 16 Storm Drain (cost shared with RCFC&WCD, SAWPA grant and preparing for construction)
• Stormwater capture from Noble and Marshall Creek
• Additional urban runoff capture and recharge from developing areas BCVWD's water management strategy since its formation has always been to maximize local water resources including local groundwater and capture and percolate surface flows in Little San Gorgonio Creek for subsequent extraction in the District's Edgar Canyon wells. With the development that occurred starting about year 2000, BCVWD began installation of a non -potable water system with the intent of using recycled water from the City of Beaumont. Currently (2020), the water demand in the non -potable system is about 12% of the total water demand. This demand is being partially met by non -potable groundwater. When recycled water becomes available, the District's non -potable demand will be primarily met with recycled water. Any additional non -potable demands will be met with non -potable groundwater.

As discussed above, BCVWD has an 80,000 AF storage account in the Beaumont Basin to purchase and store imported water when available in ample supply during wet years. In addition to SGPWA's Table A amount, there are two other sources of imported water over and that are available and are discussed within Section 7 above:

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 41 of 57 • Article 21 Water
• Turn -Back Pool Water
Section 9.3 Water Service Reliability Assessment
The amount of water available during the dry periods from BCVWD's water sources are presented below.

Section 9.3.1 Groundwater
Section 9.3.1.1. Beaumont Basin
The Beaumont Basin is managed by the Beaumont Basin Watermaster. 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, return flows, and imported water, when available. The amount of imported water that can be recharged in any year depends on DWR's SWP allocation and varies from year to year. 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 well water to compensate for the lack of rainfall. The forbearance water and return flows will also decrease during dry periods as users reduce water consumption.

Table 9-3 below (Table 7-2 in the BCVWD 2020 UWMP) 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 9-3, 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. This is believed to be conservative.

Return flow credits, included in Table 9-3 below, were not applied with a 15% reduction factor as return flows are dependent upon the conservation factors in effect during the year for which credits are given.

Edgar Canyon
Groundwater from Edgar Canyon is affected to some degree by climate change. The average annual extraction from Edgar Canyon is 2,073 AFY based on records from 1983-2020. 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, 4 -year, 5 -year and 6 -year moving averages for the extractions from 1983 -20 were determined and are presented in Table 9-2 (Table 7-3 in the BCVWD 2020 UWMP) along with the Base Period for moving averages.

Section 9.3.2 Imported Water
The amount of imported water available from the SGPWA via the State Water Project is very climate dependent. A spreadsheet was developed using the 2019 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-, 3-, 4-, 5-, 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 9-5 (Table 7-4 in the BCVWD 2020 UWMP).

For the reliability analysis, the percentages in Table 9-6 will be applied to BCVWD's estimated available imported water supplies for any particular dry year period. The results of the reliability analysis are presented in Tables 9-11 through 9-16.

By Resolution 2015-05, the SGPWA Board of Directors established an obligation to meet the future water supply needs of the region, including BCVWD. BCVWD can rely on the SGPWA to secure and deliver the imported water needed to meet BCVWD's current and future demands as set forth in this 2020 UWMP and subsequent UWMP updates in concert with DWR's Delivery Capability Reports.

Section 9.3.3. Recycled Water
Recycled water 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 current drought.

BCVWD is counting on one source of recycled water, the City of Beaumont. 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 9-7 provides an estimate of the available recycled water during extended dry periods. The amount of recycled water under normal conditions is shown in the updated Section 6 above.

Notes:

1. Taken from Table 7-6 in the BCVWD 2020 UWMP.

2. The District is currently in the process of finalizing its Non -Potable Water Master Plan, which includes more current non -potable system facility requirements and recycled water supply projections. The non- potable/recycled water supply data provided in this WSA addendum are consistent with the District's 2020 UWMP. The non-potable/recycled water supply projections are considered draft as of the date of approval of this Addendum 1. Data from the BCVWD 2020 UWMP is used for consistency.

Section 9.3.4. Storm Water and Urban Runoff Reliability (Potential Projects).

Storm water and Urban Runoff quantities are very dependent on rainfall. Review of the rainfall record at Beaumont for the period 1888 — 2006 resulted in the data shown in Table 9-8 (Table 7-7 in the BCVWD 2020 UWMP). To determine the multiple dry year rainfall as a percent of the average rainfall, the 2-, 3-, 4-, 5- and 6 -year moving averages of the annual rainfall was determined.

Section 9.4 Drought Risk Assessment
A conservative approach was taken when considering the amount of imported supply BCVWD could expect in future conditions. BCVWD has included in its anticipated imported water supplies from the anticipated Table A Allocation available (using percentages described previously in Table 9-6), as well as additional potential sources of imported water identified in SGPWA's 2020 UWMP (June 2021). In any given year, when the demand for imported water exceeds the available supply, it is reasonable to assume that the imported water will be allocated by SGPWA

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 45 of 57 in proportion to each member agency's fraction of the total imported water demand without banking. A summary of the expected allocation percentages for each agency is indicated in Table 9-9, below. Percentages as indicated were determined based on a series of White Papers (White Papers No. 1 through 7) that evaluated water supply and demand for the major retailers in the SGPWA service area.

Notes:

1. Taken from Table 7-9 in the BCVWD 2020 UWMP.

In the future, other SGPWA water retailers will require greater supplies of imported water to meet growing demands. As a result, the allocation percentages described above will continue to change. BCVWD expects to update these percentages after the adoption of the 2020 UWMP updates for the other member agencies in the SGPWA service area.

For the Single Dry Year, potable and non -potable water demands in Table 9-11 (Table 7-11 in the BCVWD 2020 UWMP) did not reflect any conservation. For 2 consecutive dry years through 6 consecutive dry years, demand reductions for potable and non -potable water were included. The estimated demand reductions (as percent) that could be seen during various multiple dry years are indicated below in Tables 9-12 through 9-16 (Tables 7-12 through 7-16 in the BCVWD 2020 UWMP).

Notes:

1. Taken from Table 7-10 in the BCVWD 2020 UWMP.

This is a reasonable assumption since there would be adequate time to implement the potential water use restrictions identified in Section 10 for a dry period lasting longer than a single year.

Tables 9-11 through 9-16 present the water service reliability assessment for single through 6 consecutive dry years.

Notes:

1. Taken from Table 7-16 in the BCVWD 2020 UWMP.

In all of the assessments, water must be extracted from BCVWD's Beaumont Basin Storage Account. Tables 9-11 through 9-16 clearly indicate the importance of maintaining substantial amounts of water in the storage account. Based on the assessment, BCVWD should keep about 12,000 AF in the storage account in order to maintain a 5 -year supply as mandated by BCVWD Resolution 2015-05, if conservation measures are in effect. The total amount required to be withdrawn from banked storage will increase if conservation measures and restrictions described in Section 10 cannot be achieved. If no conservation occurs (worst case, conservative), BCVWD will need to maintain about 52,000 AF in its storage account to meet the demands during a 5 consecutive year dry period.

August 24th, 2022
Addendum #1 - Beaumont Pointe Development Water Supply Assessment Page 53 of 57 Section 11 Conclusions (Previously Section 10 in Project's WSA) The following revisions noted in red shall be incorporated into Section 11 (previously Section 10 in the Project's WSA)

1. The projected water demand from the Beaumont Pointe Development project is 196.70 AFY of which 85.20 AFY is outdoor, non -potable water use. This equates to approximately 1`)/0 of the District existing water demand for 2020.

2. 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 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

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 Beaumont Pointe Development 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 2020 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 Project Authority.

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 2045 and beyond as outlined in Section 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 Beaumont Pointe Development 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 Beaumont Pointe WSA. BCVWD will supplement its existing supply sources during these dry periods with banked water in BCVWD's Beaumont Basin Groundwater Storage Account.

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 Section 6 through 9 in this WSA.

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 Sections 6 through 9.

Addition of Section 10 — BCVWD Water Shortage Contingency Plan The BCVWD 2020 UWMP Section 10 addresses the DWR new requirements of a District -wide Water Shortage Contingency Plan (WSCP). The following is intended to be added as Section 10 — BCVWD Water Shortage Contingency Plan to the Project's WSA to summarize the BCVWD WSCP.

SECTION 10 — BCVWD WATER SHORTAGE CONTINGENCY PLAN (WSCP) As a companion to the BCVWD 2020 UWMP and required by the State, the District prepared and approved the BCVWD 2020 Water Shortage Contingency Plan (WSCP) as a strategic planning process to prepare for and respond to water shortages. As part of this new requirement, BCVWD will assess each year's water supplies to determine if there was a water volume shortage for that year. Based on the water shortage, the District will implement one of the six water conservation levels (shown in Table 10-1 below), as defined in the District's WSCP, to encourage or require water conservation among its service area. The Beaumont Pointe Development will be subject to these water conservation levels as dictated by BCVWD.

Subject: Hidden Canyon Beaumont Distribution Center — Water Demands and Domestic Water Service Calculations
Charles Marr Consulting (CMC), partnered with Thienes Engineering Inc, has completed the analysis of the Hidden Canyon Beaumont Distribution Center (HC or Project) for the purpose of:

1. Estimating the potable and non -potable water demands

2. Defining a potable water distribution system that could be approved by the Beaumont - Cherry Valley Water District

3. Providing hydraulic calculations supporting the domestic water pipeline sizes for serving the Project from the proposed Fourth Street extension
Conclusion
The fire flow analysis performed here is conservatively based on a higher standard than required by the fire department. The District will provide the required 4,000 gpm at 20 psi for Hidden Canyon at a minimum service pressure of 20 psi. (For the purposes of a conservative analysis 5,000 gpm at 30 psi is used here.) This analysis shows that the 2650 Zone can supply up to 4,500 gpm to the Project site during emergency fireflow. Any supplemental flow to the HC project site can be provided from the proposed 4th Street PRV station and 2750 Zone.

Hidden Canyon Project Description
The Hidden Canyon development project is planned for approximately 2.9 million square feet of warehouse structures (2 separate buildings, Attachment 1) and is located in the City of Beaumont and within the Beaumont -Cherry Valley Water District service area. Access to the project site will include extension of 4th Street to the west from Potrero Boulevard.

The District recently oversaw the construction of the 24 -inch transmission pipeline in Potrero Boulevard extending their backbone 2650 Zone from north of the 60 freeway to 4th Street. The construction also extended the 2650 Zone to the east in 4th Street with a 24 -inch pipeline to the proposed location of the 2750 -to -2650 pressure -reducing valve (PRV) station.

The District's September 24, 2019 memorandum (Attachment 2) identified design PRV station flows and a preliminary layout of the station. It indicates that the 2750 Zone can provide in excess of 5,000 gpm through year 2030. Peak hour demand from future projects including 1 Charles Marr Consulting 562.781.7936

Charles Marr Consulting
Hidden Canyon, Olivewood and Jack Rabbit Trail are envisioned to require supplemental service through the PRV station with primary service from the Hannan Tank, which floats the 2650 Zone from north of the freeways. A fire hydrant flow test performed last year on the 2750 Zone upstream of the proposed PRV station at the 18 -inch pipeline loop for the recently constructed Amazon Distribution Center approximately 0.67 miles east of Potrero Boulevard confirms this.

The fire hydrant flow test (Attachment 3) hydraulic results are as follows:
• Minimum Static Pressure = 91 psi
• Maximum Static Pressure = 105 psi (Avg is calculated as 98 psi) • Observed flow = 4,000 gpm
• Residual Pressure during flow = 76 psi
The calculations performed for this technical memorandum (Attachment 4) show these hydraulic figures equate to 6,000 gpm at 72 psi at the proposed PRV station location. The 2750 Zone will be essential for redundancy and reliability of the 2650 Zone south of the 60 Freeway and west of Potrero Boulevard.

In order to confirm the Attachment 4 calculations, Thienes Engineering requested and received two additional fire hydrant flow tests for two separate fire hydrants — FH No. 1 located at Oak Valley Parkway and Linksman Drive and FH No. 2 located in 4th Street approximately one half mile east of Potrero Boulevard. The fire hydrants represent existing or proposed hydrants within the District's computer hydraulic model. District staff performed the tests using their model simulating current and future demands of the 2650 Zone with the proposed 2650 Zone PRV station in operation. The fire hydrant flow tests are included in Attachment 6, and the hydraulic results are as follows:

Fire Hydrant No. 1 (Oak Valley Pkwy and Linksman Dr)
• Minimum Static Pressure = 123 psi
• Maximum Static Pressure = 128 psi (Avg is calculated as 125.5 psi) • Observed flow = 4,000 gpm
• Residual Pressure during flow = 90.2 psi
Fire Hydrant No. 2 (4th Street east of Potrero Blvd)
• Minimum Static Pressure = 90 psi
• Maximum Static Pressure = 95 psi (Avg is calculated as 92.5 psi) • Observed flow = 4,000 gpm
• Residual Pressure during flow = 57.8 psi
It should be noted that Fire Hydrant No. 2 is located approximately at the proposed site of the PRV station. The results show a drop in pressure between static conditions and observed flow conditions of 35 psi. If the static and residual pressures were read on the 2650 Zone at the simulated fire flow location on the downstream side of the proposed PRV with pressure setting at or slightly below 2650 feet hydraulic gradient, minimal pressure loss would be expected because the PRV would act to maintain the downstream pressure setting regardless of flow. 21Page
Charles Marr Consulting
562.781.7936

Charles Marr Consulting
Therefore, it is apparent the model simulation included a pressure setting on the PRV below

57.8 psi, resulting in no flow assistance from the 2750 Zone. Therefore, in order to confirm the calculations of Attachment 4 using the two recent flow tests (Attachment 6), we provide these revised calculations with the understanding that no assistance from the PRV station occurred during the tests. Thus, during the FH No. 2 test simulation 100 percent of the Project potable water demands were supplied from the main 2650 Zone (Hanna) Tank and the Potrero Boulevard transmission main.

Hidden Canyon Water Demands
The project water demands are estimated based on one employee per 1500 square feet of office/warehouse building structure, and confirms BCVWD staff estimate in the Approved Water Supply Assessment dated February 2019, and Will -serve letter dated March 5, 2019 (Attachment 5). Irrigation demands have been updated to reflect measured acreage for the major perimeter slopes and various landscaping for strip irrigation surrounding each building, as well as planter boxes located throughout the parking area. Table 1 outlines the potable and non -potable water demands of Hidden Canyon Beaumont Distribution Center:

This is consistent with industry standard usage factors and typical landscape ordinance restrictions of recent. Peaking factors can vary based on size of development project and land use type. Based on our recent discussions with District staff, the Project will be conditioned to serve recycled water for all outdoor irrigation. Peaking for the maximum -day demand (highest volume of water used in a 24 -hour period) on the domestic water system could range from 1.5 to 4.0 times average demand. Peak -hour peaking could range from 2.0 to 4.0 times the maximum -day demand. Table 2 presents peaking of the water demands that could be 3lPage

BCVWD Water System proposed for serving Hidden Canyon
The Hidden Canyon Beaumont Distribution Center project team met with Beaumont Cherry Valley Water District staff on October 9, 2019 to discuss water service for the Project and construction status of the District's 2650 Zone domestic water system in the Project region.

With the exception of the pressure -reducing valve (PRV) station, all domestic transmission piping is completed in Potrero Boulevard south to 4th Street and in 4t" Street east to the Amazon Distribution Center where it will connect to the 2750 Zone via the PRV station.

One of the primary concerns for the District is water quality and water turnover in the piping system for Hidden Canyon. The Project will require approximately one mile of transmission pipeline in 4t" Street from the existing facilities in Potrero Boulevard, which represents a large volume of water that will only serve the Project in the interim. Thus, circulation is necessary in order to maintain water quality without regular flushing of the pipeline due to a relatively low average daily demand. This can be achieved by a dual piping system within 4t" Street connecting to the Potrero Boulevard transmission main to serve the HC project and operate in the interim specifically to circulate 2750 and 2650 Zone water, as illustrated in Figures 1 and 2:

The figures illustrate this recent solution to the water quality concern with one minor modification — a closed valve between the connection points at Potrero Boulevard. Employing the dual piping configuration with a closed valve at Potrero Boulevard and 4th Street between the two connection points for the new HC supply system will create true circulation when supplied by the proposed PRV station. The District memorandum (Attachment 2) indicates domestic water from the proposed PRV station could be used to backfeed the 2650 Zone and replenish its storage (Hannan Tank). By diverting flow through the Project site as part of a normal conveyance path to the central service areas of the 2650 Zone to the north, the District can maintain water circulation and quality during sole service to HC in the interim to this remote area. we should recommend that this continue
/ to be normal operating procedures until
demand picks up in this area
This would be a interim operating condition until more development occurs to the west of the HC project. Ultimately, the future demand to the west and north will provide the daily turnover of system water without requiring the forced circulation in 4th Street, and the closed valve can be permanently opened. The 4th Street system would be sized to equal the ultimate transmission capacity planned for future development to the west. Attachment 4 includes calculations that confirm the dual piping configuration (2 -16 -inch pipelines) for interim and ultimate operation in 4th Street west of Potrero Boulevard.

Additional calculations are performed to analyze the FH No. 1 and FH No. 2 test results that would represent the primary hydraulic source for the Project, while the PRV station to the east, supplied from the 2750 Zone would act as a secondary source for supplementing unusual peak demands and emergency fire flow. Figure 3 illustrates the location of the additional fire flow tests for FH No. 1 and FH No. 2, as well as the 2650 Zone piping required to convey flows to the proposed Hidden Canyon Distribution Center.

Attachment 7 includes the additional calculations that confirm the dual piping configuration analyzed here with the 16 -inch pipelines under interim and ultimate operation is adequate to supply 5,000 gpm fireflow during maximum -day demand. Table 3 summarizes the service pressures resulting from the 2018 flow test and the two additional flow tests recently provided by the District, as included in Attachments 3 and 6, respectively. It should be noted that the District flow tests were based on a fire flow of 4,000 gpm, and that 5,000 gpm was used for this technical memorandum to provide a conservative analysis.

[1] For May 2018 test, all Project service flow supplied through proposed 4th Street PRV and 2750 Zone. For November 2019 test, all Project service flow supplied from Hannan Tank and Potrero Blvd 2650 Zone. [2] Based on Project service elevation equal 2417'el. above mean sea level.

The District will provide the required 4,000 gpm at 20 psi for Hidden Canyon at a minimum service pressure of 20 psi. However, the analysis performed here is conservatively based on a higher standard than required by the fire department (5,000 gpm fireflow for Hidden Canyon at a minimum service pressure of 30 psi). Table 3 summarizes the calculations and indicates that the most recent model simulation tests performed by BCVWD staff show that the 2650 Zone can supply up to 4,500 gpm to the Project site during emergency fireflow. Any supplemental flow to the site can be provided from the proposed 4th Street PRV station.

For interim operation of the on -site transmission system serving only Hidden Canyon, the required length of the dual piping system from Potrero Boulevard to the HC project depends on the turnover rate by daily HC water demands that can 'consume' the volume of water in the west -most 4th Street 18 -inch deadend pipeline. For the purposes of this analysis, water turnover is proposed every eight (8) hours at average demand. Table 4 summarizes the volume calculations of various lengths of 18 -inch pipe versus HC demand for eight hours. 91Page

This shows that the volume stored in approximately 800 linear feet of 18 -inch pipeline is purged by HC demand approximately every eight hours. Therefore, 800 linear feet could be the length of service pipe at the west end of 4th Street within the HC project site. At maximum day demand, approximately three (3) times the length of 18 -inch pipe, or 2,400 linear feet, could be purged by HC demand in 8 hours.

Please let me know if you have any questions.

FROM: Joe Reichenberger PE, Senior Engineer
SUBJECT: Design of PRV on Fourth St., 2750 Zone to 2650 Zone An EPANET2 computer model was used to analyze the 2650, 2520 and 2370 Pressure Zones which are currently supplied by the Hannon Tank and a large transmission main from the Hannon Tank which runs south and crosses under 1-10 in jacked casing near Desert Lawn Drive and Champions Drive. Also, the 2750 Pressure Zone was modeled to determine the effects of the demands on the 2750 Pressure Zone through the proposed pressure reducing station. The proposed pressure reducing station on Fourth Street will act as a necessary backup and secondary supply during high demand times, e.g., peak hour demands and maximum day demand plus fire flow. The station flows were also analyzed under minimum flows. Two conditions were analyzed: Current (2020) and (projected future) 2030 demands. It is believed that a second 2650 Zone water storage tank will be constructed south of Highway 60 around 2030 or when needed depending on development conditions. In addition, a 2520 Zone tank is anticipated south of 4t" Street as shown in the District's Potable Water Master Plan.

Under normal conditions, i.e., other than maximum day demand plus fire flow and peak hour demands, Hannon Tank will be able to meet the demand and provide adequate pressure. It is under the fire flow and peak hour conditions that the pressure regulator is needed to support Hannon Tank. In the analysis, a 4,000 gpm fire flow was assumed for the Hidden Canyon Development area and/or the Olivewood Development area.

DRAFT FOR DISCUSSION
1 September 24, 2019

The 2750 Zone is able to provide 6,000 gpm currently, and about 5,500 gpm at the proposed pressure regulating station, based on development conditions in 2030. This is over and above the existing demands in the 2750 Pressure Zone. Table 1, above, shows that the potable water system will be able to meet the demands to approximately 2030. BCVWD believes the demands, particularly those for peak hour are conservative. With regulations requiring reduced outdoor water use, the normal daily peaking factors will most likely be reduced. In the analysis, a peaking factor of 2.25 times the demand on the maximum day was used for the peak hour.

Various analyses were performed with the Hannon Tank being out of service, which would result in all flows to the 2650 and lower pressure zones coming through the proposed pressure regulating station. This would put a large burden on the 2750 Zone which it would not be able to supply at the proposed regulating station. It is very unlikely that Hannon Tank will be out of service for maintenance for an extended duration. The Hannon Tank is a prestressed concrete tank constructed approximately 14 years ago; therefore it is relatively new. The Hannon Tank can be filled with water pumped from Well 29 or from the 2750 Pressure Zone. There is an interconnection between the Well 29 discharge pipeline and the 2650 Pressure Zone. In an emergency, Well 29 could be operated and pumped directly into the system without having Hannon Tank in service.

Based on the range of flows from the model, the pressure regulating station should consist of one 4", and two 8" ClaValves, Model 92-01, Pressure Reducing Valve with Pressure Sustaining Feature, class 150. This combination of sizes meets the minimum requirements and provides adequate capacity to meet the maximum day demand plus fire with the Hannon Tank out of service. A cavitation check indicates that special hardened metallurgy is not required. Table 2 shows the recommended initial valve sizing for the proposed pressure regulating stations.

Table 2
Valve Sizes and Capacities for Pressure Regulating Station on 4th St.

Diameter, Intermittent

Valve 1 4 800 4 990
Valve 2 8 3,100 15 3,900
Valve 3 8 3,100 15 6,150
Total 7,000 11,040
The pressure regulating station is designed to be expandable as development occurs in the 2650 and lower pressure zones. The station is designed with a small valve and two larger valves, to accommodate the higher demand and fire flow. The station should be set allowing the small valve to open first, followed in -turn by the larger valves as flows increase.

The pressure sustaining feature is needed to ensure there is adequate pressure in the 2750 Zone at all times. The valves shall be set to maintain a minimum pressure of approximately 70 psi in the 2750 Zone at the pressure reducing valve inlet. This will provide sufficient operating pressure in the 2750 Zone, even with 6,000 gpm going through the regulators. The valves shall be set open when the downstream pressure drops below 2650 hydraulic grade line. The 4 -in valve shall be set to open first, followed by the first 8 -in and then the second 8 -in.

Conceptual Plan for Pressure Regulating Station on 4th Street The station shall be constructed above ground (not in a vault) adjacent to 4th Street with 24 -inch or 18 -in, below grade, laterals from the 24 -in main line. Each regulator will have a 12 -in diameter riser pipeline from the 24 -inch or 18 -in lateral. Spacing shown allows for future installation of larger regulating valves and provides space for the pilot control systems on the valves.

Other requirements are:

1. Pressure regulating station is to be completely fenced (wrought iron), with a minimum 15 -ft wide access gate and meet City of Beaumont requirements, as applicable

2. Provide paved parking for a BCVWD truck or truck/crane located out of traffic (traveled way) for access, operation, maintenance, and repair of the regulating station.

3. Provide a flow meter (propeller type) on the inlet lateral. Ensure proper straight pipe distances upstream and downstream of the meter for meter accuracy

4. Provide at least 100A, 120v power to the station for: power tools, operational solenoids, flow meter SCADA, etc.

5. Install pressure gauges upstream and downstream of each valve for setting adjustment.

6. Provide space in design for future risers as necessary.

Fiscal Impact Analysis
August 2023 Beaumont Pointe Specific Plan

1. Purpose of Fiscal Impact Analysis
Representatives of JRT BP1, LLC have requested that DPFG, LLC. ("DPFG") prepare a Fiscal Impact Analysis ("FIA") to estimate the annual recurring net fiscal impact that the Beaumont Pointe Specific Plan ("Project") is anticipated to have on the City of Beaumont, California's ("City") General Fund at the Project's buildout, as well as its cumulative impact in the 20 years after buildout, if it were to be annexed into the City. Please note that the FIA is subject to limiting conditions outlined in this Report.

2. Project Description
The proposed Project is an employment and retail entertainment development which at buildout is anticipated to include approximately 246,000 square feet of general commercial uses, a 125 -room hotel, and approximately 4,995,000 square feet of industrial and warehouse uses in five buildings ranging in size from 600,000 and 1,400,000 square feet.

Beaumont Pointe Specific Plan (SP2019-0003)
The Project includes approximately 539.9 gross acres that are predominantly located just outside the City of Beaumont in the Unincorporated Area of the County of Riverside, between Moreno Valley and Beaumont, adjacent to Jack Rabbit Trail and below SR -60. The Project is within the Beaumont Pointe Specific Plan, which provides for the development of up to 539.9 acres comprising of 30.2 acres of General Commercial uses, approximately 232.6 acres of Industrial uses, and approximately 277.1 acres of Open Space. It is estimated that the Project will include an additional approximately 4,995,000 square feet of industrial uses, approximately 246,000 square feet of general commercial uses, and a 125 -room hotel upon buildout. A summary of the Project's land use assumptions is shown on the next page in Table -1, while the site plan is included in Appendix A-1. 3

(a) Anticipated revenues are shown in 2023-2024 dollars. (b) 20 year projection assumes the sum of all 20 years assuming a 1% growth per year in Transient Occupancy Tax Revenue and a 2% growth per year for all other revenue categories for 20 years.

Expenditures assume a 5% Public Safety escalation with the remaining expenditures increasing at 3% per year for 20 years. Escalation factors per City of Beaumont.

Using the same escalation assumptions in the Buildout + 20 Yrs summary in Table 2 an annual time - phased analysis was prepared consistent with the term of the City forecast of sixteen years. This analysis includes the anticipated absorption of the project over 5 years and is included in Appendix C.

4. FIA Recurring Revenues
The revenue estimates in this section utilize the Equivalent Resident approach, with the exception of property and sales taxes which are estimated from the number of commercial square feet, industrial square feet, and number of hotel rooms developed, as shown in detail in Appendix B.

4.1 Property Taxes
In addition to the other ad valorem chargers imposed by various local agencies, landowners in the State of California are required to pay annual property taxes of 1% on the assessed value of their 5

Fiscal Impact Analysis
August 2023 Beaumont Pointe Specific Plan
property pursuant to Proposition 13. Each county in California is divided into tax rate areas ("TRA").

After the basic 1% property tax is collected by the County, the tax is allocated to various local agencies based on their respective share of the basic tax within the applicable TRA. Due to the Project being located within multiple TRA's, this analysis calculates a weighted average percentage of the share of the basic tax that would be allocated to the City if the Project were to be annexed. Property taxes are estimated by applying estimated assessed values to the number of commercial square feet, industrial square feet, and hotel rooms built within the Project. If it were to be annexed into the City, the Project is estimated to generate $523,038 in annual recurring revenues at buildout and $12,708,439 in cumulative annual revenues during the 20 years after buildout as shown in Appendix B Table 4.

4.2 Property Taxes In -Lieu of MVLF
In May 2004, Governor Schwarzenegger proposed a swap of city and county VLF revenue for additional property tax share as part of a budget agreement between the State and local governments.

The swap was included in the 2004 budget package. Under this legislation, property tax in -lieu of VLF is allocated to Cities and Counties pursuant to a complex formula involving each agencies relative share of assessed value. The property tax in -lieu of VLF revenue that will be generated by the Project can be estimated by determining the (i) percentage growth in the total assessed value of the City attributable to the Project and multiplying by (ii) the property tax in -lieu of VLF revenue of $6,762,693 expected to be received by the City in FY 2023-24 per the City Budget. Based on these calculations, the Project is anticipated to generate $1,476,082 in annual recurring revenue at buildout and $35,864,922 in cumulative annual revenues during the 20 years after buildout, as shown in Appendix B Table 5.

4.3 Sales Taxes

4.3.1 Transient Occupancy Taxes
Lodging Taxes are estimated from the number of hotel rooms built within the Project. Lodging tax revenues of 10.0% on all hotel rooms rented within the Project are collected by the City. This revenue estimate utilizes a 125 -room hotel, an average hotel room rate of $160 and an occupancy rate of

75.0%. Based on the total hotel lodging taxes, if it were to be annexed into the City, the Project is estimated to generate $547,500 in annual recurring revenue at buildout and $12,055,405 in cumulative annual revenues during the 20 years after buildout as shown in Appendix B Table 6.

4.3.2 Commercial Retail Sales Taxes
Commercial retail sales taxes are estimated from the number of square feet of retail space built within the Project. If it were to be annexed into the City, the Project is estimated to generate $453,000 in annual recurring revenue at buildout. If it were to be annexed into the City, the Project is anticipated to generate $11,006,709 in cumulative annual revenue during the 20 years after buildout as shown in Appendix B Table 7.

4.4 Other Revenues
The City receives revenues from other budgetary items for which case studies were not conducted upon. These revenues are in the form of Other Taxes, Licenses, Permits, and Fees, Charges for 6

Fiscal Impact Analysis
August 2023 Beaumont Pointe Specific Plan
Service, Fines and Forfeitures, Cost Recovery, and Miscellaneous Revenue. Other Revenues are estimated using the estimated Project Equivalent Residents of 2,622. The Project is estimated to generate $554,731 in annual recurring revenue at buildout and $13,478,502 in cumulative annual revenues during the 20 years after buildout as shown in Appendix Table 8.

5. FIA Recurring Costs
The cost estimates in this section utilize the Equivalent Resident approach, as shown in detail in Appendix B.

5.1 Non Departmental
Transfers Out are the only expense that makes up the Non -Departmental cost category. Costs are estimated using a Per Capita & 50% Employee Multiplier. This analysis assumes that 0% of the non -Departmental costs for Transfers Out are estimated to be impacted by the Project. The Project is estimated to generate $0 in annual recurring costs at buildout and $0 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

5.2 Administration
The Administration cost category includes all expenses incurred by the City for Administrative services, City Council, City Clerk, Administration, Communication, IT Department, Risk and Human Resources, Legal services, and Finance and Budgeting. Costs are estimated by using a Per Capita & 50% Employee Multiplier, and 50.0% of the budgeted costs are estimated to be impacted by the Project. The Project is estimated to generate $226,753 in annual recurring costs at buildout and $6,092,928 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

5.3 Community Development
The Community Development cost category includes all expenses related to the Planning Department, Community Enhancement, Building and Safety, and Economic Development, and is responsible for administering the City's planning and construction and code regulation programs.

Costs are estimated using a Per Capita & 50% Employee Multiplier, and 50.0% of the budgeted costs are estimated to be impacted by the Project. The Project is estimated to generate $77,875 in annual recurring costs at buildout and $2,092,538 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

5.4 Community Services
The Community Services cost category includes expenses related to maintenance of parks, trails, and open space, maintenance of City owned facilities, and manages recreational operations and programs. Costs are estimated using a Per Capita & 50% Employee Multiplier, and 50.0% of the budgeted costs are estimated to be impacted by the Project. The Project is estimated to generate $167,679 in annual recurring costs at buildout and $4,505,604 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

5.5 Public Safety
The Public Safety cost category includes expenses related to providing quality law enforcement, Fire Protection, animal control, and emergency management services in the most effective and 7

efficient manner possible. A majority of the costs are related to personnel expenses and operating expenses. This analysis has also modified the Fire costs from an original budgeted amount of $6,820,202 to a total of $11,396,728 which includes an anticipated $4,576,526 for a fire contract to operate an additional fire station. Costs are estimated using a Per Capita & 50% Employee Multiplier, and 100% of the budgeted costs are estimated to be impacted by the Project. The Project is estimated to generate $1,235,317 in annual recurring costs at buildout and $40,846,946 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

5.6 Public Works
The Public Works cost category includes expenses related to the Public Works Department and the Street Maintenance Department for providing cost effective infrastructure and services to promote public health. Costs are estimated using a Per Capita & 50% Employee Multiplier, and 100.0% of the budgeted costs are estimated to be impacted by the Project. The Project is estimated to generate $250,287 in annual recurring costs at buildout and $6,725,317 in cumulative annual costs during the 20 years after buildout as shown in Appendix B, Table 9.

• Our analysis is based on currently available information and estimates and assumptions. Such estimates and assumptions are subject to uncertainty and variation. Some assumptions inevitably will not materialize, and unanticipated events and circumstances may occur; therefore, the actual results achieved may vary materially from the forecasted results. The assumptions disclosed in this Report are those that are believed to be significant to the estimates of results.

7. General Sources of Information and FIA Methodology
Annual recurring revenues/costs were calculated using the City of Beaumont's Fiscal Year 2024 Adopted Budget ("Budget"), as this was the most recent budget available. Annual recurring revenue/cost impacts to the City General Fund are estimated in 2023 dollars, and by using primarily either per person ("Per Capita") or equivalent resident ("Equivalent Resident") methodologies. In some simpler instances the FIA estimates impacts based on the number of Project commercial square feet, industrial square feet, or number of hotel rooms.

The Equivalent Resident approach is used for annual recurring revenues/costs that are impacted by the number of Project employees. This approach uses the Budget's revenues/costs, as well as the City's number of residents plus 50.0% of the employees in 2023 to establish an Equivalent Resident Factor. The Equivalent Resident Factor is then applied to the number of Project residents plus 50.0% of Project employees to estimate annual recurring fiscal impacts. 50.0% is estimated to be the percentage of Project employees that will live and shop in the City.

These approaches are summarized on Table -3.
