For Water Subcommittee Meeting [November 9, 2022]
TO: Honorable Water Subcommittee Members
APPROVAL: Thomas J. Crowley, P.E., Utilities Manager
FROM: Toyasha Sebbag, Assistant to the City Manager
Request Water Subcommittee receive and file the Technical Memorandum on the impacts of the City of Rialto 2021-2029 (Sixth Cycle) General Plan Housing Element Update on Water and Wastewater Utilities.
BACKGROUND:
On March 8, 2022, the City Council conducted a public hearing and adopted Resolution No. 7845 Adopting a Mitigated Negative Declaration (Environmental Assessment Review No. 2021-0044) for and Approving the City of Rialto 2021-2029 (Sixth Cycle) General Plan Housing Element Update (General Plan Amendment No. 2021-0002).
The Housing Element identifies available candidate housing sites and establishes the City’sofficial housing policies and programs to accommodate the Regional Housing Needs Assessment (RHNA) goals as determined by the Southern California Association of Governments (SCAG). The programs and policies established within the Housing Element guide future decision-making to achieve the City’s housing goals for the 2021-2029 planning period.
At the direction of the Water Subcommittee, a detailed analysis of the impact of the sixth cycle housing element on water/wastewater utilities within the city of Rialto was conducted. Attachment 1, Draft Technical Memorandum performed by Dopudja & Wells Consulting provides this analysis.
ANALYSIS/DISCUSSION:
Most importantly from a water and wastewater utility perspective, the Housing Element identifies parcels through the City that would require “Rezoning”or “Upzoning”to meeting housing unit goals within the City. These Rezoned and Upzoned parcels are projected to contain a housing density higher than that allowed by the adopted General Plan; the potentially greater number of housing units on these parcels would require more water and wastewater utility capacity than that required by the adopted General Plan. The Rezoned and Upzoned parcels fall into two main geographic categories: 1) north of Baseline Avenue in the eastern half of the city; and 2) parcels along Foothill Boulevard between Larch Avenue and Cactus Avenue.
Table 2 show the housing units above the General Plan totals in the three water service areas. The majority of the impact falls within the Rialto Water Service area.

The following sections of this TM provide an evaluation of the impacts to water and wastewater capacity requirements within the City if the Rezoning and Upzoning opportunities identified in the Housing Element were to be implemented.
Water System Impact: Demand factors from the City of Rialto Water Master Plan were used to estimate the increased water demand. Values of 95 gallons per day per capita (gpdc) and 3.85 people per housing unit were used in these estimates because these values are appropriate for high- density residential development. Table 3 shows the increased amount of water demands for the new Housing units by service area.
89% of the net housing unit increase is found in the Rialto Water Service area within Pressure Zone City of Rialto Printed on 11/3/2022Page 2 of 4

89% of the net housing unit increase is found in the Rialto Water Service area within Pressure Zone
2. Therefore, the total required demand increase is 2,200 acre-feet-per-year (AFY) by 2045. This results in a forecasted water supply shortfall of 258 AFY, see table 4 below.
Mitigation Measure: The Rialto Utility Authority will need to invest in small increases in the available water supply. Over the next several years investments will be made in recharging storm flows and imported water for the Rialto, Lytle Creek and Bunker Hill groundwater basins where the City gets the majority of its water supplies. This recharge will allow for additional supplies for the future. Hydraulic improvements are not required.
Wastewater System Impact: Table 5 provides the wastewater flow projections for the collection system as developed for the Wastewater Master Plan. As shown in the table, the maximum flow projection for the collection system from the Wastewater Master Plan is 10.03 million gallons per day (mgd). This value is increased to 10.83 mgd with the addition of the Rezoned and Upzoned parcels.
The increased projection remains less than the average permitted capacity of the City’sWastewater Treatment Plant, which is 11.7 mgd. Treatment capacity increases will not be required for the Rezoned and Upzoned parcels of the Housing Element.
Mitigation Measures: First, north of Baseline Avenue in the eastern half of the city was identified in the Wastewater Master Plan as being deficient in trunk gravity main capacity, and the increased City of Rialto Printed on 11/3/2022Page 3 of 4

23 File #: WS-22-1017, Version: 1, Agenda #:
the Wastewater Master Plan as being deficient in trunk gravity main capacity, and the increased housing units in the Rezoned and Upzoned parcels will exacerbate this lack of capacity. Therefore, the Sycamore Avenue Trunk Capacity Project identified in the Wastewater Master Plan should be implemented to provide sufficient capacity for these parcels. Second, between Larch Avenue and Cactus Avenue along Foothill Boulevard, there is a reach of a 10-inch diameter pipeline which is insufficient to convey the increased flows. 2,600 feet of 10-inch gravity main should be upsized to 12- inch gravity main if the Rezoned and Upzoned parcels are implemented.
FINANCIAL IMPACT:
Operating Budget Impact
None.
Capital Improvement Budget Impact
The new Water and Sewer Master plans will identify the additional improvements required.
RECOMMENDATION:
Staff recommends that the Water Subcommittee receive and file the Technical Memorandum on the impacts of the City of Rialto 2021-2029 (Sixth Cycle) General Plan Housing Element Update on Water and Wastewater Utilities.

SUBJECT: IMPACT OF SIXTH CYCLE HOUSING ELEMENT ON WATER/WASTEWATER UTILITIES WITHIN THE CITY OF RIALTO
DATE: OCTOBER 27, 2022
This Technical Memorandum (TM) is comprised of the following sections:
• Background
• Identification of Rezoned and Upzoned Parcels Within City • Impacts of Rezoned and Upzoned Parcels to Water Utility Capacity Requirements • Impacts of Rezoned and Upzoned Parcels to Wastewater Utility Capacity Requirements
BACKGROUND
As described in Plan to House Our Rialto, 6 th Cycle Housing Element 2021-2029, Adopted March 8, 2022 (Housing Element), the Housing Element is a state-mandated chapter of the City of Rialto General Plan that identifies and analyzes the City’s housing needs and includes a detailed outline and work program of the City’s goals, policies, and quantified objectives related to housing. The Housing Element also addresses the maintenance and expansion of the housing supply to accommodate households currently living and expected to live in the City during the specified housing cycle. The Housing Element identifies available candidate housing sites and establishes the City’s official housing policies and programs to accommodate the Regional Housing Needs Assessment (RHNA) goals as determined by the Southern California Association of Governments (SCAG). The programs and policies established within the Housing Element guide future decision- making to achieve the City’s housing goals for the 2021-2029 planning period.
Most importantly from a water and wastewater utility perspective, the Housing Element identifies parcels through the City that would require “Rezoning” or “Upzoning” to meeting housing unit goals within the City. These Rezoned and Upzoned parcels are projected to contain a housing 25 Rialto Housing Element Utility Impact TM 002_22_02
density higher than that allowed by the adopted General Plan; the potentially greater number of housing units on these parcels would require more water and wastewater utility capacity than that required by the adopted General Plan. Because the City’s Water Master Plan and Wastewater Master Plan have been developed based upon ad opted General Plan housing densities, as is typical, implementation of the Housing Element potentially would require water and/or wastewater capacity beyond that projected in the two master plans. The following sections of this TM provide an evaluation of the impacts to water and wastewater capacity requirements within the City if the Rezoning and Upzoning opportunities identified in the Housing Element were to be implemented.
IDENTIFICATION OF REZONED AND UPZONED PARCELS WITHIN THE CITY Appendix B of the Housing Element contains the “Inventory of Adequate Sites” for housing within the City. This inventory contains both parcels that are currently underutilized for housing under existing densities, and parcels whose housing density could be increased to allow more housing units. The latter group of parcels were identified for Rezoning and Upzoning.
The parcels identified for Rezoning and Upzoning are presented in several tables and figures in Appendix B of the Housing Element. For this evaluation, the Upzoned and Rezoned parcels were consolidated into a single Geographical Information System (GIS) database to allow for mapping and for location-based evaluation of water and wastewater utility system impacts. The Rezoned and Upzoned parcels fro m the Housing Element are presented on Figure 1. The parcels are grouped by general development area. The net increase of housing units in the City beyond those projected by the adopted General Plan are summarized in Table 1. To arrive at these values, the housing units allowed on a specific parcel under the adopted General Plan density were subtracted from those allowed by the Rezoned or Upzoned density for each individual parcel. In most cases, the Rezoned or Upzoned density was projected to be 35 housing units per acre. As can be seen in Table 1, the net increase in housing units resulting from the Rezoned or Upzoned parcels is approximately 5,600 units.

IMPACTS OF REZONED AND UPZONED PARCELS TO WATER UTILITY CAPACITY REQUIREMENTS The City of Rialto is served by three separate water utilities: City of Rialto Water Serv ices, West Valley Water District, and Fontana Water Company. Therefore, the impact of Rezoned and Upzoned parcels depends on the location of the parcel, and the resulting water utility service area into which it falls.
Figure 2 overlays the Rialto Water Service Area, including pressure zone delineation, with the Rezoned and Upzoned parcels shown previously on Figure 1. As can be seen on Figure 2 , the majority of the Rezoned and Upzoned parcels are found within the Rialto Water Service a rea. A small number of these parcels in the north of the City are found within the W est Valley Water District; a still smaller number are found at the western edge of the City along Foothill Boulevard in the Fontana Water Company service area. The net increase in housing units is broken down by water utility in Table 2. As can be seen in the table, 89% of the net housing unit increase is found in the Rialto Water Service Area. The majority of the housing unit increase is found within Pressure Zone 2 of the Rialto Water Service distribution system.

Demand factors from the City of Rialto Water Master Plan were used to estimate the increased water demand for each water utility in the City. Values of 95 gallons per day per capita (gpdc) and
3.85 people per housing unit were used in these estimates; both values are appropriate for high density residential development.
The resulting water demand increases can be seen in Table 3. As shown in the table, the total required supply increase is 2,200 acre feet per year (AFY). 2,000 AFY of this value is required in the Rialto Water Service Area.

The required water supply increase for the Rezoned or Upzoned parcels is compared to the available water supply for each utility in the City in Table 4. The available water supply for each utility was taken from the utility’s 2020 Urban Water Management Plan . As shown in the table, small increases in available water supply would be required for Rialto Water Service and Fontana Water Company. Hydraulic improvements are not required in the Rialto Water Service distribution system to serve the increased water supply.

IMPACTS OF REZONED AND UPZONED PARCELS TO WASTEWATER UTILITY CAPACITY
REQUIREMENTS
The City of Rialto provides wastewater utility service to the entire City, and therefore there is only one wastewater utility impacted by the Rezoned and Upzoned parcels. The Rezoned and Upzoned parcels are presented in overlay of the wastewater collection system on Figure 3. 31 Rialto Housing Element Utility Impact TM 002_22_02
Figure 3. Rezoned and Upzoned Parcels Overlaid with City of Rialto Wastewater Collection System 32 Rialto Housing Element Utility Impact TM 002_22_02
Table 5 provides the wastewater flow projections for the collection system as developed for the Wastewater Master Plan. As shown in the table, the maximum flow projection for the collection system from the Wastewater Master Plan is 10.03 million gallons per day (mgd). This value is increased to 10.83 mgd with the addition of the Rezoned and Upzoned parcels . The increased projection remains less than the average permitted capacity of the City’s Wastewater Treatment Plant, which is 11.7 mgd. Treatment capacity increases will not be required for the Rezoned and Upzoned parcels of the Housing Element.

In terms of the wastewater collection system impact, the Rezoned and Upzoned parcels fall into two main geographic categories . There are a significant number of such parcels at and north of Baseline Avenue in the eastern half of the City. This portion of the City was identified in the Wastewater Master Plan as being deficient in trunk gravity main capacity, and the increased housing units in the Rezoned and Upzon ed parcels will exacerbate this lack of capacity. T he Sycamore Avenue Trunk Capacity Project identified in the Wastewater Master Plan must be implemented to provide sufficient capacity for these parcels.
33 Rialto Housing Element Utility Impact TM 002_22_02
The second main geographic category contains the parcels along Foothill Boulevard. In general, there is sufficient trunk capacity along and running south from Foothill Boulevard to c onvey the increased flow away from the impacted parcels. However, between Larch Avenue and Cactus Avenue along Foothill Boulevard, there is a reach of 10-inch diameter pipeline which is insufficient to convey the increased flows. 2,600 feet of 10 -inch gravity main should be upsized to 12 -inch gravity main if th e Rezoned and Upzoned parcels are implemented. This reach can be seen on Figure 4.

Final Construction Work Authorization to Rialto Water Services in the amount of $684,304.89 for the Emergency Repair of City Well 4A and the Rehabilitation of Chino Well 2.
BACKGROUND:
City Well 4A: On September 28, 2022, City Well 4A experienced a catastrophic failure of the internal main feed wiring. The main feeds had a direct short with the cabinet destroying all components and wiring inside the Motor Control Center (MCC). Due to this, the existing MCC enclosure was damaged and all internal components (breakers, wiring etc.) were destroyed or damaged. Since City Well 4A is a critical well supplying water to the Rialto drinking water system, Rialto Water Services (RWS)Veolia personnel immediately contacted the local electrical on-call contractor, Big Sky Electric (BSE) to evaluate the situation. It was concluded that the two panels would need to be completely rebuilt. The MCC in City Well 4A was installed in the 1990s and has been in continuous operation since it was installed.
These panels were shipped to BSE’ssite for repair on October 4, 2022 and is anticipated to be rebuilt and shipped back in 6-7 weeks (mid to late November 2022). Upon completion of rebuilding of the panels, an Arc Flash test and certification will be completed prior to being placed into service.
Additionally, RWS/Veolia is working with Tri County Pump Company (TCPC) to ship the existing motor to TCPC’srepair workshop for disassemble, inspect, test, recondition, and cleaning. Upon completion of the repairs, TCPC’s personnel will come onsite and reinstall the pump motor and perform startup.
Finally, RWS/Veolia will contract with Prime System, the on-call Instrumentation & Controls contractor, to load the backup program into the new PLC system, establish communication with the main SCADA system, test, and re-commission the site.
This project will be completed by the end of the year, December 2022.
Chino 2 Well: Currently, the pump in Chino Well 2 has been operating with an oil lubricated system.
The oil that is used as a lubricant is a food grade oil allowed under our operating permit with the Division of Drinking Water. Due to the age of the oil lubrication system, RWS/Veolia is seeing an increase of oil colleting on top of the water in the well. In anticipation of the lubrication pump system failing, RWS/Veolia is recommending that the oil lubrication system be replaced with a water lubrication system.
This well does feed the Perchlorate Treatment System installed at this well site. One of the benefits City of Rialto Printed on 11/3/2022Page 1 of 2

This well does feed the Perchlorate Treatment System installed at this well site. One of the benefits of replacing the lubrication system with a water lubrication system is that it will protect the Ion Exchange (IX) media. If the oil were to enter the IX treatment system, the IX media would be damaged and a change out of media would be required. This project would replace the system from an oil lubricated system to water lubricated system, similar to the City’sMiro # 3 and Rialto #3 wells and EPA’s EW1 well.
This project will be completed by the end of March 2023.
FINANCIAL IMPACT:
The total amount for the FCWA is $684,304.89. A detailed breakdown of the cost is in the table below.
Funding for this project will be paid for with the remaining water Facility Improvement Plan (FIP) Funds held by Rialto Water Services in the Capital Trust Account. As of the beginning of the Fiscal Year there were $5,043,334.06 available in the Water FIP funds. The Council issued a Final Construction Work Authorization on August 9, 2022, in the amount of $2,982,691 for the water improvements in Riverside Central Project utilizing Water FIP funds. The balance available for use on this project is $2,060,643.06
RECOMMENDATION:
Staff recommends approving a Final Construction Work Authorization to Rialto Water Services in the amount of $684,304.89 for the Emergency Repair of City 4A Well and the Rehabilitation of Chino 2 Well.

Update on the Advanced Metering Infrastructure (AMI) Implementation Project.
BACKGROUND
The 2022 Urban Community Drought Relief Program is one of three Department of Water Resources (DWRs) Drought Relief Grant Programs that offer financial assistance to address drought impacts.
Staff believes the Advanced Metering Infrastructure (AMI) project is appropriate for this grant program. AMI is an integrated system of smart meters, communications networks, and data management systems that enables two-way communication between utilities and customers. This will help households reduce their water and energy consumption, lowering their bills and carbon emissions.
The Department of Water Resources (DWR) released the final 2022 Guidelines/Proposal Solicitation Package in October 2022 and will accept applications between October 10, 2022, and January 31, 2023. The estimated program funding is $300 million with a minimum grant opportunity of $3 million per applicant. Currently, there is no maximum grant amount; however, DWR reserves the right to establish a maximum award size depending on the applications received and funding availability.
Agencies awarded funding is scheduled to be announced between December 2022 and March 2023.
Therefore, it is advantageous to apply for consideration early.
The total cost of the AMI project is $8 million, see Attachment 1. Currently the city applied for $2 million in grant funding from the U.S. Department of Interior’s(Department) WaterSMART (Sustain and Manage America’sResources for Tomorrow) Program, and staff was notified that an award is pending. An agreement with the Bureau of Reclamation is scheduled to be provided by February 2023. This grant comes with a 50% cost share. Therefore, the outstanding city cost portion from the WaterSMART grant would be $6 Million.
The City is requesting from DWR $6 million for the remaining amount required for the project. This amount will cover the city’s50% cost share portion and the remaining costs of the AMI project. Must be noted that DWR may fund only a portion of the request. Resolutions will be presented to City Council during the November 15th council meeting requesting authorization for staff to apply for the grant, accept grant funds and execute contract documents.
