Subject: Introduce and Waive the First Reading of Ordinance No. 2023-01, Amending the Hughson Municipal Code
Pertaining to Title 15 Building Code Regulations
Presented By: Carla C. Jauregui, Community Development Director Approved By: _________________________
City Manager
Recommendation:
Introduce and waive the first reading of Ordinance No. 2023-01, amending Title 15 Building and Construction of the Hughson Municipal Code, and adopting by reference, the California Building Standards, 2022 Edition, Title 24 of the California Code of Regulations, with amendments and other uniform codes.
Background & Overview:
The model codes update every three years to improve and adjust to the newest materials, methods of construction, and technological advances in the industry. The California Building Standards Commission’s adoption of the 2022 California Building Code (CBC) comes after a comprehensive multi-state agency and stakeholder update of the 2019 California Building Code.
The objective is to produce a practical building code that ensures public safety first and foremost while implementing the most efficient technology available to conserve the State’s natural resources and energy use. California’s Building Code applies to every commercial and residential structure in the State.
The new 2022 CBC contains twelve parts that incorporate public health, life safety, and general welfare standards used in the design and construction of buildings in California. These parts incorporate the latest national standards in the International Building, Residential and Fire Codes, California Green Building Code, California Energy Code, National Electrical Code and the Uniform Mechanical and Plumbing Codes.
CITY COUNCIL AGENDA ITEM NO. 5.2
SECTION 5: PUBLIC HEARING
Health and Safety Code Section 18941.5 mandates that the Building Standards contained in the 2022 CBC shall be effective 180 days after publication by the California Building Standards Commission. If these codes are not adopted by Ordinance, they become effective by default without any amendments. The proposed effective date for the City of Hughson will be January 1, 2023. As part of the adoption process, this department has made every effort to notify all affected parties of the proposed changes.
Discussion:
Along with the usual Energy and Green code updates, below are a few noteworthy updates:
• Permit expiration has been extended from 6 months to 12 months. Every permit shall remain valid if the work on the site is commenced within 12 months after its issuance.
• Aging-in-place design and fall prevention have been added for new residential construction. Added to address specific design elements to facilitate access to operational features and to allow people to stay longer in their homes as they age.
• Expanding Electric Vehicle Charging requirements to install EV charging receptacles and chargers in new multifamily dwellings, hotels, and motels.
The second reading of the Ordinance will return to Council on February 14, 2023.
Fiscal Impact:
There are no fiscal impacts with the adoption of this ordinance and code amendment.

Staff Recommendations:
1. Adopt Resolution No. 2023-09, affirming the City of Hughson’s commitment to supporting the Riverview Mobile Home Estates Water Consolidation Project.
2. Authorize the City Manager to execute the Letter of Support.
Background:
Riverview Mobile Home Estates (RMHE) is a small community water system, located in Stanislaus County, CA, Water System No. 5000090. RMHE currently provides water services to 173 connections and a population of 540 residents. The annual median household income for the system is $35,000, categorizing it as a Severely Disadvantaged Community (SDCAC).
In May 2016, the RMHE received a compliance order from the Stanislaus County Department of Environmental Resources (No. DER-16CO-006) for violation of the uranium MCL (Maximum Contaminant Level) of 10 mg/L. While RMHE financed several projects to address the water contamination problem, none of these efforts resulted in permanent results or prospects for sources that meet drinking water standards.
The State Water Resources Control Board, Division of Drinking Water (DDW) assigned Self-Help Enterprises (SHE) to RMHE on August 31st, 2020, to provide CITY COUNCIL AGENDA ITEM NO. 6.2
SECTION 6: NEW BUSINESS
technical assistance and aid with their water contamination issues. From August 2020 to January 2023, Self-Help Enterprises and Black Water Consulting Engineers, Inc. (Black Water) have been working with RMHE to identify and implement a longterm solution that will address their uranium contamination issues.
Discussion:
A Feasibility Study (Attachment B) was prepared by Black Water in April 2021.
According to the Feasibility Study, Alternative 4 - Consolidation, was the consultant's selected project alternative. Three consolidation options were explored and considered: Stanislaus Regional Water Authority (SWRA), City of Modesto, and the City of Hughson. Other alternatives that were considered in the Feasibility Study included the following:
Table 1: Explored Alternatives and Findings
Explored Alternatives Findings
Construction of a new well
The RMHE owners previously evaluated this
option with Quality Service in the past.
Kleinfelder drilled a test hole on June 4, 2018,
to evaluate the water quality at a potential new
well location. The laboratory testing results for
the test hole returned high levels of gross
alpha and uranium that exceeded the DDW’s
maximum contaminants (MCLs). The
determination was made at the time that the
development of a new well was not a feasible
solution to addressing the water system’s
problem.
On-site water treatment plant
The feasibility of constructing a groundwater
treatment facility at RMHE was evaluated by
Kleinfelder, Inc. in September 2019. The major
components of the design included
discontinuing the use of the south well in favor
of beginning the use of the north well,
installation of a new storage tank and booster
pump system, filtration system, electrical
improvements, and equipment startup and
testing. Quality Service’s cost estimate for the
entire project totaled $886,293 making it an
unaffordable option.
Consolidation
1) City of Hughson
2) City of Modesto
3) Stanislaus Regional Water Authority
(SRWA)
The DDW instructed SHE and Black Water to conduct water consolidation outreach to all the nearby entities and develop an Affordability Study. The consolidation outreach findings are listed below in Table 2: Consolidation Outreach & Findings, and an Affordability Study Draft (Attachment C) was prepared by Black Water in September 2022. The purpose of the Affordability Study is to determine appropriate and affordable water rates for Riverview Mobile Home Park customers while ensuring the City of Hughson operation and maintenance staff, city staff, and existing customers are not unfairly burdened as a result of the water consolidation.
City of Hughson Water Engineer, Cort Abney, prepared a Cost/Revenue Evaluation to identify budgetary expenses, rates, and revenues associated with the proposed consolidation project, in which the City of Hughson provides a potable water supply to the Riverview Mobile Home Estates. Black Water will be working in conjunction with the City of Hughson and Cort Abney to complete the Final Affordability Study.
Table 2: Consolidation Outreach & Findings
Consolidation
Outreach
Findings
City of Hughson Feasible – If water capacity is increased (1.94 miles from RMHE)
City of Modesto Not feasible – insufficient water capacity and distance (3.80 miles from RMHE
Stanislaus Regional
Water Authority (SRWA)
Not feasible – outside the Turlock Irrigation District
service area (1.26 miles from RMHE
City of Waterford Not feasible – insufficient water capacity and distance (3.70 miles from RMHE)
The consolidation outreach efforts conducted by Self-Help Enterprises and the Regional Board identified the City of Hughson as the system’s only water consolidation option, with the stipulation that additional water supplies would need to be constructed as part of the project to address the City’s water capacity issues.
Based on the Affordability Study Draft, the total cost of the construction project would approximately be $12,137,072 and the maximum State Grant awarded amount would be $14,080,000. Included in the total cost, and based on information provided by Cort Abney, the City’s contracted water engineer, the estimated cost for expanding the City of Hughson facilities is $7,500,000. The $7,500,000 includes the first phase of the North Facility Project, which includes the addition of a new storage tank and booster pumps that would provide an additional 500 units of water.
Water Consolidation Project Benefits – City of Hughson
1. Based on the current Intended Use Plan (IUP), the RMHE Project is eligible for up to 100% Planning Grants/Principal Forgiveness ($60,000 per connection or up to $80,000 for good cause) funding due to the following reasons:
a. The RMHE Community is an SDAC: $35,000< 60% of State MHI – Category A-C project
b. The project qualifies as a high-priority project that addresses public health issues:
Compliance Order from Stanislaus County Department of Environmental Resources violation of Uranium (No. DER-16CO-006).
2. Consolidation projects are eligible for grant funding, regardless of the project category. The Division of Financial Assistance may approve up to $80,000 per connection and 100% for good cause of the construction project. At 173 service connections, RMHE would be eligible for up to $13 million. The 13 million grant can cover the extension of the water service from the Hughson water system to connect to RMHE, the necessary City of Hughson Water System Improvements, and the disconnection and destruction of the existing groundwater wells.
It is important to note that the State Water Resources Control Board – Division of Financial Assistance (DFA) will make their final determination of the recipient’s project grant/loan and outline all conditions in the awarded funding agreement which cannot be definitively determined until the drinking water construction application is submitted and reviewed.
Table 8: Estimated Project Cost Breakdown in the Affordability Study Draft Item Amount
Consolidation Improvements
$ 4,637,072
Hughson Water System Improvement
$ 7,500,000
Total
$12,137,072
Maximum Grant Amount – DFA
$14,320,000
3. The City of Hughson might be eligible for the Consolidation Incentive Funding:
a. If a Public Water System (PWS) acts as an administrator to one or more SCWSs. Up to $5 million in 0% financing for an Incentive Project; or Grant funding of up to $2,500/connection when acting as an administrator for a small DAC water system or up to $5,000/connection for a small SDAC water system for an Incentive Project. Max of $1 million grant is available per water system.
b. If the City of Hughson is a voluntary participant in consolidation, the receiving water system is eligible to receive incentive funding. Phase 1 of the project may qualify for a consolidation incentive project for up to $10 million in 0% financing. IUP home page:
https://waterboards.ca.gov/water_issues/programs/grants_loans/srf/docs /dw-grant-fact-sheet.pdf. This Program can help begin the first phase of the City’s North Facility Project to increase water capacity. The North Facility Project would increase the City’s water capacity by approximately 500 equivalent residential units and Riverview currently has 173 connections which would allow for future expansion on the City’s part.
4. While Riverview Mobile Homes Estates does not have plans to expand in the next few years. Should the Mobile Home Park Owner want to expand, they would need to get approval from the City to expand their water use or demand.
5. Throughout the planning and construction phase of the Water Consolidation Project the City of Hughson’s contracted water engineer would be a 2nd consultant on the project in addition to Black Water to review plans on behalf of the City.
6. To support consolidation, DFA, in coordination with DDW, will continue to emphasize consolidation opportunities by providing project financing and technical assistance. Consolidation Incentives can provide grant funding for infrastructure improvements to mitigate drinking water risks.
Fiscal Impact:
Hughson staff would continue to work with the State Water Resources Control Board as needed to ensure that the best interests of the City are considered. The City contracted water engineer will be paid for by State project funding through Self-Help Enterprises.

4 2 Water System Description
This section provides a description of the Water System’s sources and facilities. Figure 2 provides a schematic map of the Water System’s service area and Figure 3 provides a schematic map of the well site flow process.
2.1 Water System Facilities
The RMHE Water System consists of two (2) active wells that supply the potable water system. The first well is referred to in the Permit as the South Well, PS Code 5000090-002 (South Well) and the second well is referred to as the South West New Well, PS Code 5000090-013 (South West Well). The wells operate in an alternating lead/lag pumping style that helps balance the burden on a single well.
The South Well was constructed in 1978. The South Well is 220-feet deep with a 50-foot annular seal and a 10-inch diameter steel casing. The South Well is equipped with a 240-gallon per minute (gpm), 20- horsepower (HP) submersible pump. The South West Well was constructed on May 20, 2004. The South West Well is 140-feet deep with a 95-foot bentonite annular seal and a 10-inch diameter PVC casing. The South West Well is equipped with a 300-gpm, 20-HP submersible pump. Each well has a 4-inch galvanized steel discharge pipe, source water sample tap, check valve, totalizing flow meter, and an emergency backup generator system.
Only the South West Well discharges to a 10,000-gallon hydro-pneumatic pressure tank. The South West Well also has a bypass pipe that allows water to be pumped directly to the distribution system. The water from both active wells remains untreated before entering the distribution system. The pressure tank is equipped with a 4-inch diameter drain to waste valve at the bottom of the tank that allows periodic flushing to remove accumulated sediment. The pressure tank is configured with a pressure switch that controls the deep well pump operation based on system demand. An air release valve and air compressor balance the air to water ratio within the pressure tank. The South Well connects directly to the 6-inch diameter distribution system after passing through a 6-inch diameter isolation valve. The discharge pipe from the pressure tank connects to the 6-inch diameter distribution system just downstream of the isolation valve on the pipe leading from the South Well. The South West Well bypass pipe connects to the 6-inch distribution system just upstream of the South Well isolation valve. Both the pressure tank discharge pipeline and the South West Well bypass pipeline have 6-inch isolation valves to allow operators manual control of water leading to the distribution system.
The water distribution system consists of approximately 5,750 feet of 1-½-inch diameter to 6-inch diameter pipelines and 176 ¾-inch service laterals of varying length. The Water System also supplies ten (10) fire hydrants located throughout the RMHE.
The Water System has two additional wells referred to as the North East Well and the North Well. The North East Well was abandoned in August 2003. The North Well was constructed adjacent to the North East Well as a replacement source and has remained inactive since the well was developed in October 2000.

The South Well and the South West Well operate in an alternating lead/lag style. The data summarized in Table 1 above represents the total combined flow readings from both active wells. The highest monthly water usage based on the data is 2.02 million gallons (MG) in June 2018. This value was used to estimate the system demands.
The average day demand (ADD) was estimated using the highest monthly water usage. The maximum day demand (MDD) was estimated by multiplying the ADD with a peaking factor of 1.5. The peak hour demand (PHD) was estimated by multiplying the MDD with a peaking factor of 1.5. Table 2 summarizes the estimated ADD, MDD, and PHD based on the California Waterworks Standards.

8 The South Well capacity of 240 gpm and the South West Well capacity of 300 gpm are both sufficient to meet the demands of the Water System. There is no other impact on the peak flow demand on the Water System because it does not provide water for irrigation purposes.
2.3 Water System Operation and Maintenance History
RMHE contracts with Quality Service, Inc. for operation and maintenance (O&M) of the Water System.

The required operation and monitoring tasks associated with the Water System represent a significant cost incurred by the RMHE Owners. Since the compliance order for uranium maximum contaminant level (MCL) exceedances was issued by the County DER, additional monitoring of the Water System has been required. Consequently, there have been added costs to monitor and sample the wells for uranium and other specific constituents, laboratory testing, and reporting to the County. A detailed breakdown of the O&M plan is in included in Appendix B.

9 3 Problem Description
This section describes the identified Water System deficiencies that affect the ability of the system to comply with regulations and provide a reliable, efficient, and safe source of drinking water that meets water quality standards. The groundwater source water quality affects the reliability of the Water System to produce drinking water compliant with water quality standards. In addition, the RMHE Owners incur a significant cost to have the Water System operated and maintained by Quality Service. Several options can address the issue of poor water quality, such as developing a new well or constructing a groundwater treatment facility, but only consolidation with a public water will address the cost to operate and maintain the Water System.
3.1 Water Quality
The Water System groundwater source has concentrations of uranium that exceed the MCL of 10 mg/L.
On May 10, 2016, the County DER issued a citation (Citation No. DER-16CO-006) to RMHE for uranium concentration exceedances of the MCL. County Compliance Order No. DER-16CO-006 is included in Appendix C. The original sample was collected in June 2015 from water produced by the South Well (PS Code 5000090-002). As a result, the Water System was required to begin quarterly uranium monitoring of each non-compliant well. Table 4 shows the uranium monitoring results provided by RMHE to the County DER.

The County DER determined that the Water System violated the California Health and Safety Code, Section 116555 and Section 64442, Title 22, CCR, since the water produced by the South Well during the monitoring period exceeded the uranium MCL on average. More recent samples taken from each active well in 2018 show, both, the South Well and South West Well exceeded the uranium MCL. The RMHE Owners post a Public Health Notice each quarter for exceedance of the 20 pCi/L MCL established for uranium, the first having been issued in September 2016 and the most recent issued for the 2nd quarter of 2020 in July.
Table 5 and Table 6 summarize the water quality for constituents sampled from 2017-2018 for the South Well and South West Well, respectively. The full Summary of Source Water Quality report is included in Appendix D.

11 The raw water from the South Well and South West Well have multiple constituents present that are near or above the respective MCL’s, in addition to uranium. In testing performed on February 14th, 2017, nitrates were detected at 9.5 mg/L and 8.2 mg/L in the South Well and South West Well, respectively.
These are just under the 10 mg/L MCL for nitrates and has required additional monitoring by operations staff. In testing performed on August 15th, 2018, the gross alpha levels were detected at 19.2 pCi/L and
34.2 pCi/L in the South Well and South West Well, respectively. These are both above the MCL of 15 pCi/L.
3.2 Operation and Maintenance
Costs to operate and maintain the Water System have resulted in a financial burden on the RMHE customers. The Water System must retain Quality Service to perform the extensive operations and monitoring tasks required to properly maintain the equipment. The costs of these services have increased since the compliance order was issued due to an increase in water quality sampling, lab testing, and reporting.

12 4 Consolidation Analysis
There are three potential consolidation options to connect to a community water system near the Riverview Mobile Home Estates. Three watersystems within four miles include the City of Hughson, a City of Modesto-owned water system in the unincorporated County island town of Empire, and the Stanislaus Regional Water Authority (SRWA). Each potential service consolidation option will be evaluated as independent alternatives in Section 5. Figure 4 provides an overview of conceptual pipeline improvement alignments for RMHE to consolidate with each agency.

14 5 Alternative Analysis
Improvement alternatives were developed to determine strategies for future improvements to the existing Water System to address the identified deficiencies. Four (4) alternatives were considered to evaluate the project including: 1) No project; 2) On-site water treatment facility; 3) Drilling a new well; and 4) Consolidation with a nearby Community Water System (nearby community water system options include Hughson, Modesto, and the SRWA).
5.1 Alternative 1 – No Project
This alternative assumes the Water System will continue to operate in its present condition and no improvements to the Water System are considered. No improvements to the Water System will result in continued exceedances of the uranium MCL and possible MCL exceedances of other constituents. The long-term health of the RMHE community will be negatively impacted. There will be no immediate capital cost, however the O&M costs for RMHE customers will be significant and increase over time as the water quality declines.
5.2 Alternative 2 – On-site Water Treatment Facility
This alternative includes the construction of an on-site water treatment facility at RMHE that is capable of treating raw groundwater with high levels of uranium and other specific constituents.
The feasibility of constructing a groundwater treatment facility at RMHE was evaluated by Kleinfelder, Inc. in September 2019. Kleinfelder prepared a proposal, included in Appendix E, to design a new treatment facility for removal of uranium and other constituents. The major components of the proposal included discontinuing the use of the South Well by replacing the source with the North Well, installing a new packaged treatment system to remove uranium from the water source utilizing ion exchange technologies, chlorine disinfection, system rehabilitation involving well pump condition assessments and Variable Frequency Drive (VFD) retrofit, storage reservoir upgrades by repurposing the 10,000-gallon hydro-pneumatic pressure tank as a make-shift wet-well for booster pumps, and distribution booster pump station. Kleinfelder’s proposed fee for providing the design in the outlined scope of work was $77,865. Kleinfelder did not provide a construction cost estimate.
Quality Service also prepared a proposal, included in Appendix E, for the design and construction of a new groundwater treatment facility in August 2019. The proposal included design, engineering, and permitting for the installation and testing of a full-scale ion-exchange water filtration system for radium and uranium removal. The major components of the design included discontinuing the use of the South Well in favor of beginning use of the North Well, installation of a new storage tank and booster pump system, filtration system, electrical improvements, and equipment startup and testing. Quality Service’s cost estimate for the entire project totaled $886,293.
The construction of a new groundwater treatment facility to treat the on-site well water for uranium is costly. The cost estimates discussed above do not include the continued O&M costs that the RMHE Water System would require. These costs would increase after the completion of a new groundwater treatment facility due to additional equipment to monitor.
Riverview Mobile Home Estates Water System
Feasibility Study Report
April 2021
15 5.3 Alternative 3 – Construction of a New Well
This alterative includes the development of a new on-site well to replace the active wells with high uranium levels. A possible solution to reduce the uranium levels in the RMHE Water System is to drill and develop a new well that could have better water quality than the South Well and the South West Well.
RMHE Owners previously evaluated this option with Quality Service in the past. Kleinfelder drilled a test hole on June 4, 2018 to evaluate the water quality at a potential new well location. The laboratory testing results for the test hole returned high levels of gross alpha and uranium that exceeded DDW MCL’s. The determination was made at the time that development of a new well was not a feasible solution to address the Water System’s problem. Refer to the Summary of Source Water Quality in Appendix D.
5.4 Consolidation Alternatives
Three (3) consolidation options have been considered to address the RMHE Water System’s deficiencies.
A project consisting of consolidation with an established water service agency has common details shared by all three (3) alternatives. Those general commonalities are discussed in this section. For clarity, the water service agencies will be referred to as “Consolidating Agency” and “Consolidating Water System” throughout this section. The unique benefits and challenges associated with each consolidation alternative will be discussed in the following subsections.
The designated Consolidating Agency will own, operate, and maintain a new water transmission pipeline.
The transmission pipeline will establish a connection between the RMHE Water System and the nearest existing transmission main of the Consolidating Water System. The connection point at RMHE will be at the well site south of Jantzen Road at the 6-inch isolation valves located downstream of the existing pressure tank. Each consolidation option will include the following components at a minimum:
• Install a new master meter at the connection to the RMHE Water System inlet to provide usage data for the Consolidating Agency.
• Installation a backflow prevention device at the connection to the RMHE Water System. • Demolish the existing 10,000-gallon hydro-pneumatic pressure tank. • Abandon the wells on site.
• Transmission main from the Consolidating Agency to serve the RMHE Water System All new system infrastructure and facilities will be designed to the Consolidating Agency’s standards. The Consolidating Agency will own, operate, and maintain the proposed transmission pipeline to RMHE, including the master meter. RMHE will own, operate, and maintain the existing RMHE water distribution system and new backflow preventer. The Consolidating Agency will require an easement right-of-way for the new transmission pipeline and facilities.
Consolidation efforts will require a water service agreement between RMHE Owners and the Consolidating Agency to establish the terms of agreement including, at a minimum, the responsibility of each party, physical limits of responsibility for O&M of facilities, and service rates. The water service agreement will require Stanislaus Local Agency Formation Committee (LAFCO) review and approval on the expansion of Consolidating Agency’s jurisdiction and sphere of influence. It is anticipated that the Consolidating Agency will apply for an emergency out-of-boundary service application with LAFCO.
Riverview Mobile Home Estates Water System
Feasibility Study Report
April 2021
16 Option 1 – City of Hughson
This option includes the consolidation of the Water System with the City of Hughson (COH) water system.
The COH owns and operates eight (8) groundwater wells, six (6) that were constructed between 1970- 1990 and two (2) new wells developed in 2019. Only five (5) of the eight (8) groundwater wells are currently considered active, with three (3) of five (5) having arsenic treatment capability. The COH was issued Compliance Orders for arsenic and nitrates in 2012, initiating the development of new wells that could treat for arsenic. The COH issued a public notice indicating that their water system has exceeded the arsenic MCL of 10 mg/L over the last four quarters in August 2020.
The nearest existing transmission main of the COH water system is on E Hatch Road. Approximately 1.94 miles of transmission pipeline will be required to connect the RMHE Water System to the COH water system. The new transmission pipeline will need to connect to the COH existing water system via a hot tap tee fitting and addition of gate valves installed per COH standards. Additional improvements required include the following:
• Trench and install transmission pipeline at a 36-inch minimum depth first heading east on Hatch, then North on Geer Road, east on Jantzen Road to the RMHE connection point. • Bore and jack operation to cross the Ceres Main Canal. • The new transmission pipeline will cross the Tuolumne River on Geer Road by connecting to the side of the bridge with U-bolts.
Option 2 –City of Modesto
This option includes the consolidation of the Water System with the City of Modesto (COM) water system.
The COM’s existing water service area consists of one large “contiguous service area” and several smaller “outlying service areas” including Empire, Salida, portions of north Ceres, and several others. The COM’s existing water supply includes surface water and groundwater sources. In the 1990’s, the COM and Modesto Irrigation District (MID) formed a Domestic Water Partnership, and the result was the construction of the Modesto Regional Water Treatment Plant (MRWTP) that became operational in 1995.
The MRWTP is owned and operated by MID and the COM purchases wholesale treated surface water from MID. The MRWTP’s current average supply is 60 million gallons per day (mgd). The COM has a total of 92 existing groundwater wells in the contiguous service area, 77 of which are currently active. The active groundwater wells have the capacity to supply approximately 107 mgd of groundwater. The COM’s contiguous service area is primarily supplied by water from the MRWTP, with the groundwater supply serving to supplement the treated surface water supply.
The portion of the COM service area that is nearest to the RMHE is in the outlying town of Empire. Empire is located on State Highway 132/Yosemite Avenue, east of the COM. Empire is primarily served by a supply of treated surface water from the MRWTP.
The nearest existing transmission main of the COM water system in Empire is on East Yosemite Avenue.
Approximately 3.89 miles of new transmission pipeline will be required to connect the water systems, making this the longest length of pipeline required out of all consolidation options. The new transmission pipeline will need to connect to the COM existing water system via a hot tap tee fitting. Additional improvements required include the following:
Riverview Mobile Home Estates Water System
Feasibility Study Report
April 2021
17 • Trench and install transmission pipeline at a 36-inch minimum depth from Empire heading east on Yosemite Avenue, south on Geer Road, and east on Jantzen Road to the RMHE connection point.
• Bore and jack operation to cross Modesto Lateral Number One.
Option 3 – Stanislaus Regional Water Authority
This option includes the consolidation of the Water System with SRWA water system. The cities of Ceres and Turlock are currently supplied solely by groundwater sources. The cities of Ceres and Turlock formed the SRWA in 2015. SRWA is currently in partnership with Turlock Irrigation District (TID) to construct a multi-benefit Regional Surface Water Treatment Plant (RSWTP) to diversify regional water supplies. The project consists of an intake structure on the Tuolumne River, pump station, water treatment plant, and pipelines to deliver water to service areas. The project is set to begin in 2021 and the new RSWTP is expected to be operational by 2023. RMHE will connect to the SRWA water system by connecting to one of the future delivery pipelines from the RSWTP.
Based on a review of SRWA Regional Surface Water Supply Project drawings, the nearest transmission force main (FM) of the SRWA water system will be a new 30-inch FM that will be installed parallel to the Ceres Main Canal on the north bank. The Ceres Main Canal (and future 30-inch FM) intersects Geer Road at the intersection of E Hatch Road and Geer Road. This will be the ideal location to connect a transmission pipeline that leads to the RHME Water System. The new transmission line will need to connect to the SRWA existing water system via a tee fitting. Approximately 1.26 miles of new transmission pipeline will be required to connect the water systems, making this the shortest length of pipeline required out of all consolidation options. Additional improvements required include the following:
• Trench and install transmission pipeline at a 36-inch minimum depth from the connection point at E Hatch Road and Geer Road, north on Geer Road, and east on Jantzen Road to the RMHE connection point.
• The new transmission pipeline will cross the Tuolumne River on Geer Road by connecting to the side of the bridge with U-bolts.
5.5 Alternative Evaluation
Alternative 1 – No Project was not evaluated as this alternative does not address the Water System deficiencies. Alternative 2 – On-site Water Treatment Facility and Alternative 3 – New Well Development were not evaluated as past efforts to address the Water System deficiencies included these options and they were determined not feasible. Alterative 4 – Consolidation is determined to be the most feasible alternative to address the Water System deficiencies. The three options for consolidation were evaluated and assigned scores based on financial and non-financial criteria, using a weighting factor system.
The evaluation criteria in this Report includes considerations for life cycle costs, environmental sustainability, operations and maintenance, and community impacts and benefits. Each option was reviewed based on the evaluation criteria shown in Table 7. The weighting factors were determined based on each criterion’s relative importance, with higher weighting factors for criteria judged to have greater importance in the evaluation.

The three options were scored from the most desirable (3) to the least desirable (1) for each evaluation criterion. The evaluation criteria are summarized in the following sections. 30-year Life Cycle Cost
Capital costs and O&M costs for each alternative were developed and incorporated into a 30-year life cycle cost (LCC). The LCC assumed a real interest rate of 1.5 percent. Table 8 provides a summary of the estimated costs. Scoring of the options for this category was based on the estimated LCC. The option with the lowest LCC was given the highest score. The option with the highest LCC was given the lowest score.

Environmental Sustainability
Environmental sustainability considerations include the protection of natural resources, climate change, water and energy efficiency, and efficient use of land. The State Planning Priorities, as listed in Section 6504.1 of the Government Code were key factors that were also used to assign a score to an option’s environmental sustainability. This portion of the Government Code is intended to promote equity, strengthen the economy, protect the environment, and promote public health and safety in the State.
The factors specifically listed in the State Planning Priorities include: 1) Promote infill development; 2) Protect environmental and agricultural resources; and 3) Encourage efficient development patterns. Table 9 presents the scoring of the three options, from most desirable (3) to least desirable (1) with regard to environmental sustainability.

Option 3 – Consolidation with SRWA 3
Riverview Mobile Home Estates Water System
Feasibility Study Report
April 2021
19 Option 3, consolidation with SRWA, was assigned the highest score because this alternative provides infrastructure to deliver a source of water that has compliant drinking water quality. Option 3 does this in the most efficient way compared with other options because Option 3 requires the least length of new transmission pipeline, minimizing the impact of construction on the public. It also has the lowest project cost, minimizing the burden on taxpayers. Construction of the transmission pipeline can take place in parallel with the construction of the RSWTP, reducing the overall impact to the public.
Option 1, Consolidation with the COH, was assigned the lowest score because this option does not immediately address the need of a water source with compliant drinking water quality. The COH water system is solely supplied by groundwater which has arsenic concentrations that tested above the MCL recently.
Operations and Maintenance
Operations and maintenance criteria consider the ease associated with each option for operating and maintaining the system. Options that are simpler or require less equipment and labor received the highest score. Due to each consolidation option requiring the same amount of O&M tasks at the RMHE site, options were evaluated only on the cost to maintain the transmission pipeline and distance for operations staff to travel to the RMHE site. All three options eliminate O&M responsibilities of RMHE staff. Table 10 presents the scores of the three options, from most desirable (3) to least desirable (1) with regard to O&M.
Table 10 – Operation and Maintenance Scoring
Option and Description Score
Option 1 – Consolidation with City of Hughson 2
Option 2 – Consolidation with City of Modesto 1
Option 3 – Consolidation with SRWA 3
Option 3 received the highest score due to proximity of the upstream connection point to RHME.
Operators would have the least distance to travel outside the existing reach of their service area to provide routine inspections. No options considered are expected to significantly increase the O&M responsibilities of each respective water system agency.
Community Impacts and Benefits
Community impacts and benefits consider the effect that each option may have on the community.
Options 2 and 3 equally benefit the community of RMHE by providing a reliable water source of good quality. Scoring of each option will consider impacts construction will have on the community outside of RMHE and evaluate any potential impacts on the community currently served by the agency of each consolidation option. Table 11 lists the scores for the three options, from most desirable (3) to least desirable (1).

20 Option 3 was assigned the highest score because this option will have the least impact on the public during construction. This is due to the shorter length of transmission pipeline required which causes the least amount of traffic interruption during construction. It can also be constructed at the same time as the SRWA RSWTP construction, avoiding two separate instances of traffic interruption. Providing the RMHE community with high quality treated surface water will directly address the current issue they face.
Option 1 was assigned the lowest score because of the combination of the water quality issues currently associated with the COH water system and the impact construction activities would have on the community. Option 1 is the only alternative that involves consolidation with a water system that is solely dependent on groundwater sources. These groundwater sources have had recent history of exceeding the arsenic MCL. Consolidation with this water system would cause an additional burden on the community for a problem they are already addressing. This option also requires boring and jacking to cross the Ceres Main Canal. The bore and jack operation would have to take place in or near residential areas and could have a significant impact on the community.
Summary
Table 12 summarizes the raw score and weighted scores assigned to each option. Option 3 had the highest total weighted score of 3.0. Based on the evaluation criteria, Option 3 is the recommended project.

21 6 Selected Project
The selected project is Alternative 4, Option 3 – Consolidation with SRWA. Consolidation with SRWA addresses the Water System deficiencies identified in the problem description by accomplishing the following:
• Providing a reliable water source to meet drinking water quality requirements. • Eliminating the O&M of the well water system responsibilities and reducing costs incurred by RMHE. SRWA would take over responsibility of operating and maintaining the distribution system.
No land will be purchased or acquired for this project. Right-of-way or easement acquisition is anticipated for the installation of the transmission pipeline within roadways or in shoulders. Coordination with landowners and investigation of existing utilities along the proposed route of the transmission pipeline are features of the design that will need to be carefully considered.
This project will require negotiation with SRWA to establish a water service agreement between RMHE Owners and the SRWA. This agreement will establish the terms of agreement including, at a minimum, the responsibility of each party, physical limits of responsibility for O&M of facilities, and service rates.
LAFCO requirements and coordination will be necessary to expand the SRWA’s Sphere of Influence to include the RMHE. LAFCO coordination will include additional fees to the project that are accounted for in the cost estimate. The project will be consistent with the SRWA standards and the Department of Public Works Stanislaus County Standards and Specifications.
The new water system will have a new master meter installed at the RMHE distribution system service connection. Since the new water source will be treated surface water that is compliant with drinking water standards, the water meter and abandonment of two (2) active wells are considered green components of the project. Abandoning two (2) active wells and one (1) inactive well and transitioning to a supply of treated surface water helps balance the demand on water sources and protects against the overdrawing of groundwater aquifers. This project includes the demolition of a 10,000-gallon hydro-pneumatic storage tank as the connection to the SRWA water system will provide sufficient capacity to meet the potable water system MDD.

II) System Description
Source Water Wells
The River View Mobile Estates Water System consists of (2) ground water well sources.
Each well contains a submersible pump which is controlled from a pressure switch that is located on the 10,000 gallon hydro pneumatic pressure tank. The current operation allows for the wells to alternate as the lead/ lag source of water. The submersible pumps discharge piping manifold together prior to the inlet connection on the hydro pneumatic pressure tank.
The following is a description for each of the ground water sources; South Well ID# 5000090-002 (Assumed to be) Constructed in 1978 10” diameter steel casing
220’ completed well depth
Annular seal depth/ gravel pack information unknown

Water System Operation Plan
March 2015
Water Storage and Distribution System
The pressure tank for the facility consists of a 10,000 gallon hydro pneumatic pressure tank. The pressure tank provides storage capacity for the water distribution system. After both submersible pump discharge piping manifolds together and prior to the influent tank connection is an existing port. This port will be the location the chlorination injector will be installed. The air balance in the hydro pneumatic pressure tank is provided through an auxiliary air compressor which is mounted on top of the pressure tank and controlled by a probe.
Excess air is released out of the tank by a ¾ inch air volume controller mounted on the tank.
The hydro pneumatic pressure tank contains a 4” drain to waste valve off the bottom of the pressure tank. This allows for periodic flushing to help remove sediment which may have settled at the bottom of the tank. The discharge off the pressure tank consists of a 6” discharge connection with appropriate isolation valves. On the discharge piping a sample tap has been constructed to allow for water quality monitoring.
The pressure tank is also configured with the pressure switch that controls the deep well pumps operation. Also, the pressure tank is equipped with an air release valve that allows for the proper air to water ratio within the pressure tank.
The distribution system consists of 175 customer service connections. Water mains consist of 6” and 8” main line pipe. The System contains 8 fire hydrants and 5 water sample locations.
III) Chlorination System Decommissioning
Proposed steps for the removal of the chlorination system from use at Riverview Mobile Estates: If at any point in the decommissioning process a positive bacteria sample is present for bacteria, a set of repeat samples will be collected, a sample from each well and three sample from the distribution. If the repeat samples are positive, the proper public notification will go out to the residents and the chlorination system will go back on line. Once it is determined the decommissioning process can continue, it will start at day one. If the repeat samples come back clean the decommissioning will continue as proposed. If any bacteria samples come back E. coli positive, confirmation samples will be collected and the chlorination system will be immediately placed in service after the confirmation samples are collected.
Distribution system sampling for Disinfection By-Products and Chromium is no longer be accomplished once the chlorination system is of line.

Water System Operation Plan
March 2015
7) Bacteriological Failure: Once the water system is notified from the lab that a bacteria sample is positive, five repeat samples will be collected within a 24 hour period from time of notification. The five repeat samples will be collected in accordance with the sample site plan. The site of failure will be confirmed with the lab by the certified distribution operator. The system will be flushed and the four samples will be collected with chlorine residuals in accordance with the sample site plan. The chlorine residuals will be noted on the lab chain of custody. If any of the repeat samples collected come back positive for bacteria the Stanislaus County Department of Environmental Resources will be contacted immediately. The correct type of notices, for the bacteria count and type, will be posted. The certified distribution operator will conduct an investigation for the possible cause of the bacteria failure. Once the problem is identified the problem will be corrected and the water distribution system will be disinfected. After the disinfection process is complete and all the disinfectant has been out of the distribution system for a minimum of 8 hours, then four “other” bacteria samples will be collected in accordance with the sample site plan. The chlorine residuals that were taken with the samples will be noted on the lab chain of custody. Once all the samples are absent of bacteria Stanislaus County Department of Environmental Resources will be contacted with lab results and the County will lift the notice. 8) Names and Contact Information-Chain of Command
See attached “Emergency Notification Plan”
9) Emergency Notification Procedure: In the event of an emergency, the water system is small enough that posting notices and hand bills should be enough warning for water users of the problems and safety protection procedures that need to be taken to protect themselves during an emergency. The potable water system will remain on a “Do Not Drink” or “Do Not Use” notice until all discrepancies are corrected; all precautionary steps are taken, and will continue normal operation with the permission of Stanislaus County Department of Environmental Resources after all repairs and discrepancies have been made.
10) Emergency Repairs: Emergency procedures to get water system operational will be done by the certified water distribution operator. All repairs and required maintenance will be documented and completed in a timely manner. Bacteria samples will be collected as required and Stanislaus County Department of Environmental Resources will be notified of the cause of the emergency and the work that was done to correct the water problem.

RE: Test Well Drilling Results
Riverview MHP
8200 Jantzen Road
Stanislaus County, California
___________________________________________________________________________________ This memorandum presents a description of field activities and results from test well drilling at the subject property. The work was performed in accordance with Kleinfelder’s proposal for services dated March 23, 2018, and industry standards. The scope of work performed includes test well drilling and logging and zone testing for water quality, as described below.
TEST WELL DRILLING AND LOGGING
Prior to mobilizing to the field, Kleinfelder cleared the site for underground utilities by contacting Underground Services Alert (USA). A site meet was conducted with Mr. Dave Frediani to determine the drilling location (Figure 1) and identify know utilities nearby. In addition, a health and safety plan was prepared for field work activities and reviewed each day before work began.
Kleinfelder contracted with Masellis Drilling of Modesto, California, for drilling services. Masellis is C-57 licensed water well contractor in California. Masellis acquired a drilling permit from Stanislaus County and mobilized to the site on June 4, 2018 to begin work.
A Midway 1500 drill rig was utilized by Masellis to drill the test well (KB-01). The boring was drilled to a total depth of the hole (400 feet below ground surface) using a conventional mud rotary drilling system with an 8 inch diameter spade bit. A trench was dug adjacent to the boring and drill rig to circulate drilling fluid and remove drill cuttings from the hole. Lithology was recorded from the drill cuttings and samples were collected every 10 feet or at discernible changes of lithology. A Kleinfelder Professional Geologist (PG) logged the soils encountered according to ASTM D2488. The complete boring log is included in Appendix A. Following drilling of the boring, an electronic log (E-log) was performed by Hydro-Tech Inc. of Madera, California (Appendix B) to further analyze the formation lithology.

ZONE TESTING FOR WATER QUALITY
Upon completion of the E-log, the data was analyzed and 2 zones were identified (120-149 feet and 250-271 feet) for collection of discrete water quality samples. Groundwater was measured in the hole at 77.50 feet below ground surface. The boring was reamed to 295 feet with an 11 inch diameter roller-cone bit using drilling additives to stabilize the hole. A coarse sand was used to backfill the hole from 295 feet to 276 feet, and a bentonite seal was placed from 276 to 271 feet. A 4 inch diameter perforated well screen was placed from 260 to 268 feet, and the coarse sand was used as filter pack around the well screen to a depth of 250 feet, with an upper bentonite seal from 250 to 245 feet.
After the sand pack and seals were placed, the zone was purged by airlifting through the 4 inch pipe using a 1.5 inch air hose with an Ingersoll Rand 375 air compressor. After the sand content decreased and the water clarity improved, the air hose was removed and a Grundfos 1.5 Horsepower, 2 inch diameter pump was installed to further purge the test well. During purging, the water quality parameters were monitored for sand content, pH, temperature, electrical conductivity, total dissolved solids, dissolved oxygen and turbidity.
Once the water quality parameters stabilized, a water sample was collected from the zone (250- 271 feet). Groundwater samples were collected from the sampling port of the discharge piping into laboratory prepared bottles. The bottles were given a unique sample identification label and packaged on ice in cooler pending transportation under chain of custody protocol to the analytical laboratory.
Another water sample was collected from the 120-149 foot zone using the same procedures and methodologies previously described.
The water samples from each zone were submitted to California Laboratory Services (CLS) of Rancho Cordova, California, an accredited analytical laboratory, for analysis by the indicated method for the following:
General Minerals (STDM/EPA)
Sodium Adsorption Ratio, Langelier Index, Aggressive Index (Calculations) Nitrate and Nitrite as N (EPA 300)

Upon completion of the collection of groundwater samples, the casing and pipes were removed from the boring and the hole was backfilled with sand and gravel to 60 feet below ground surface and then with a bentonite-grout mix to the surface under the observation of a Stanislaus County inspector. The hole was covered with a plywood cover so that the hole can be converted to a well at a later date. If the hole will not be converted to a well, Masellis will return and plug the hole with a concrete cap.
Purge and development water from each zone sample was discharged to the adjacent field on the subject property. Cuttings from the test well were spread on site. Field activities were concluded on June 7, 2018.
ANALYTICAL RESULTS
Shallow 120-149 feet
The following analytes were reported in concentrations exceeding California Title 22 Regulated Drinking Water Maximum Contaminant Levels (MCLs) or Secondary Maximum Contaminant Levels (SMCLs) in the water sample collected from 120-149 feet:
Gross Alpha was detected at a concentration of 51.4 picocuries per liter (pCi/L), exceeding the MCL of 15 pCi/L.
Uranium (radiological) was detected at a concentration of 38.9 pCi/L, exceeding the MCL of 20 pCi/L.
Aluminum (total) was detected at a concentration of 0.27 milligrams per liter (mg/L), exceeding the SMCL of 0.2 mg/L. Dissolved aluminum was not detected above the laboratory reporting limit.
Total Dissolved Solids (TDS) was detected at a concentration of 580 mg/L, exceeding the SMCL recommended range of 500 mg/L.
Total coliform and E. coli (a subset of fecal coliform) were reported as present in the water sample collected at 120-149 feet. Typically for permitted small public water systems the presence of total coliform in more than one water sample in one month is considered to be in exceedance of the MCL.
Deep 250-271 feet
The following analytes were reported in concentrations exceeding California Title 22 Regulated Drinking Water MCLs or SMCLs in the water sample collected from 250-271 feet:
Total aluminum and dissolved aluminum were detected at concentrations of 0.3 mg/L and
0.49 mg/L respectively, exceeding the SMCL of 0.2 mg/L. 20190044.001A/SAC18M82530 Page 4 of 5 August 17, 2018

KLEINFELDER 2882 Prospect Park Dr., Suite 200, Rancho Cordova, CA 95670 p | 916.366-1701 f | 916.366-7013 Total coliform was reported as present in the water sample collected at 250-271 feet.
For the complete analytical laboratory report see Appendix C.
A blending analysis of the two zones was not completed due to the high variability of the water quality particularly as it pertained to the uranium level found in the shallow zone 38.9 pCi/L which exceeded the MCL of uranium of 20 pCi/L by almost 2x’s.
CONCLUSIONS AND RECOMMENDATIONS
The shallow water sample collected at 120 to 149 feet has exceedances of the MCL or SMCL for gross alpha, uranium, aluminum, and TDS. In addition, both total coliform and E.coli were reported as present. We do not recommend the groundwater from this zone be considered for consumption.
The deep water sample collected at 250 to 271 feet has an exceedance of the SMCL for total aluminum and dissolved aluminum. In addition, total coliform was reported as present. Both aluminum and coliform are relatively easily treated at or near the well head with filtering and disinfection processes. We recommend the deeper zone be considered for production of water for the mobile home park. Based on these results the preliminary well design should include:
8-inch diameter well extending to a total depth of 280 feet. The well screen should extend from 250 to 270 feet.
The bottom ten feet should be a blank sump.
We recommend a gradation analysis be completed on the soil samples collected during drilling to be used for well screen (aperture opening) and filter pack gradation. Soil samples were retained at Kleinfelder’s materials laboratory and can be processed for a fine and coarse grain gradational analyses.
