CANNABIS FUNDS—

PERMITS VS TAXES
Cannabis funds vary by month, due to the
differences in frequency and allocation of either type
of fund. There are two ways the city collects cannabis
revenue: taxes and permits.

Due quarterly at the end of January, April, July, and
October, taxes form the bulk of the funds collected.

Taxes are broken down into two subsets, gross
receipts (percentage) and canopy space (square
footage used). Due to a large percentage of the
companies paying taxes based on their gross
receipts and the industry slowing down, there has
been a decrease in the amount of taxes brought in
this year as compared to the previous year.

Permits are collected for each company annually and
are spread throughout the year. Permits have been
historically obtained with the city for permits the
company did not strictly need, as it is easier to renew a permit than to obtain one. However, this year due
to a decrease in business, operators have been
surrendering their permits that have not been in use.

TAXES
Gross Receipts: Comprised of Retail,
Manufacturing, and Distribution, this is
the largest group. The taxes paid are 3%
of the quarterly income.

Canopy Space: Cultivation and Nurseries (a
subcategory of cultivation that handles
seeds and immature plants) make up this
category. The taxes paid are $1.25 per
square foot used for production.

PERMITS
There are several types of permits, the
Department of Cannabis Control lists the
following:

Manufacturing: Creation of cannabis
products
Retail: Sale of cannabis
Distribution: Transportation of cannabis
Cultivation: Growth of cannabis
Testing Laboratory: Testing of cannabis or
cannabis products

BUDGET REVENUE
The Cannabis Compliance Department has exceeded budget for the previous two years. The percentage of funds collected from permits for 2024 was 22% while the percentage of funds collected from taxes was 78% (rounded to the nearest percent). Similarly, the percentage of funds collected from permits for 2025 was 23% while the percentage of funds collected from taxes was 77% (rounded to the nearest percent). Revenue was reduced in 2025 for several reasons, primarily that there was a decrease in sales which impacted taxes and the surrender of permits rather than renewal. This led to a decline from the previous year, though still above budget. In the two-year period that this covers, the percentage of revenue generated from permits and taxes is 22.43% and 77.57%, respectively.

The Department also began collecting past due payments from the companies. The total collected in a six-month span was $185,693. Of that sum, 90.89% came from overdue taxes owed while 9.11% was from overdue permit fees. Overdue taxes and permit fees were discovered within the scope of the audits conducted and it is anticipated that over the next couple of years all overdue taxes will be paid or in the process of a payment plan with the City.

CONCLUSION
The Cannabis Compliance Department has collected a total of $12,382,179 over the past two years, with 78% deriving from tax collections and 22% from permits. Tax collection is performed on a quarterly basis with the payment due on the last day of January, April, July, and October. Permit fees are due upon renewal, which varies for each company.

The department, in conjunction with the Code Enforcement Department, conduct inspections to ensure compliance from the operators within the city. Violations that arise are typically swiftly corrected by operators within a 30-day period. The department may assess fines if prompt action to resolve any violations are not taken. Departmental contact between the California Department of Cannabis Control and the California Department of Tax and Fee Administration allows for smooth acquisitions of permits within the city for the operators and ensures that all operators are up to date on their state permits and taxes.

DATE: January 28, 2026
TO: Honorable Mayor and City Council Members
FROM: Jessie Flores, City Manager
SUBJECT: RESOLUTION 26-02 OF THE CITY COUNCIL OF THE CITY OF

ADELANTO AUTHORIZING THE CITY MANAGER TO APPLY FOR

PROHOUSING INCENTIVE PROGRAM FUNDS
STAFF RECOMMENDATION:

Staff recommends that the City Council adopt the attached resolution authorizing the City Manager to apply for the Prohousing Incentive Program Funds.

BACKGROUND:

The City received its official Pro-Housing Designation letter from the California Department of Housing and Community Development (HCD) on May 28, 2025, confirming the City’s eligibility under the State’s Pro-Housing Program.

On September 30, 2025, HCD released the Notice of Funding Availability (NOFA) for the fourth round of the Prohousing Incentive Program (PIP Round 4). To receive funding under this program, the City must submit a separate application.

A similar resolution was previously adopted on November 26, 2024, and this updated resolution reflects higher scoring criteria and increased eligible funding under the current round. This resolution authorizes the City to submit a Pro-Housing Incentive Program (PIP) application for up to six hundred twenty thousand dollars ($620,000) to support housing activities in Adelanto.

ANALYSIS:

The Prohousing Incentive Program (PIP), administered by the California Department of Housing and Community Development (HCD), rewards jurisdictions with pro-housing policies by providing funding and additional points in competitive applications for housing and infrastructure programs. These points enhance a city’s ability to secure financing for affordable housing initiatives.

The City has applied for approval as a pro-housing jurisdiction, qualifying it to apply for up to $620,000 in PIP funds. These funds will directly support initiatives that address the City’s housing needs by facilitating the development of affordable housing for extremely low to moderate-income households. The City’s housing needs analysis highlights the necessity of expanding affordable housing to meet demand.

By securing PIP funds, Adelanto will strengthen its capacity to finance and implement housing projects, 94 furthering its affordability goals.

The proposed resolution enables the City to submit its PIP application and utilize the funds for the following activities:
• Creating a revolving loan program for downpayment assistance ($35,000). • Lending funds to HHI of 120% and below median income ($585,000).

ENVIRONMENTAL IMPACT:

There are no anticipated environmental impacts associated with the submission of this application.

FISCAL IMPACT:

There is no fiscal impact resulting from the submission of this application.

SUBJECT: RECEIVE AND FILE THE CITY’S SINGLE AUDIT AND
INDEPENDENT AUDITORS’ REPORT FOR THE FISCAL YEAR
ENDED JUNE 30, 2023 (FINAL REPORT)
STAFF RECOMMENDATION:

It is recommended that the City Council receive and file the City’s Single Audit Report for the fiscal year ended June 30, 2023.

BACKGROUND:

The audit of the City’s Single Audit and Independent Auditors’ Report for Fiscal Year 2022/2023 (FY22/23) has been completed by the independent auditor, The Pun Group, Accountants & Advisors.

The financial statements are intended to reflect the City’s compliance with grant requirements. A government agency is only required to have a single audit performed if there was federal grant funding used in excess of $750,000. The City does not meet this requirement every year, thus it is not an annual audit. In FY22/23, there was one major program with over $750,000 spent.

The major program was the County of San Bernardino’s (the “County”) CDBG – Entitlement Grants Cluster under CDFA listing number 14.218 with a total of $1,056,084. Of these funds $437,706 were used towards the Target Area Road Rehabilitation project and $336,105 were used for North Adelanto Road Rehabilitation Project. Another $250,000 was used for North Adelanto Infrastructure Improvement Projects which included White Avenue and Jonathan Street.

The City received an unmodified opinion, meaning the Schedule of Expenditures of Federal Awards (the “SEFA”) is fairly stated in all material respects in relation to the basic financial statements of the City.

FISCAL IMPACT:

There is no fiscal impact at this time.

RE: December 2025 Adelanto WWTP Asset Management Monthly Report Dear Jessie,
Please find attached the December 2025 Asset Management Report for the Adelanto Wastewater Treatment Plant (WWTP). This report provides a summary of key operational activities, performance metrics, compliance status, and any notable issues encountered during the reporting period.

Key Highlights:
- Plant Performance: All influent was successfully treated by Adelanto WWTP. All other constituents with the PERC Water-Adelanto WWTP remained compliant with the discharge requirements specified in Order No. RV6 -2014-0058, WDID No. 6B369805001. - Critical Issues: 13-Year-old SCADA radio communications equipment is failing. It’s recommended to replace radios with fiber optic hard wiring.
- Maintenance & Repairs: see attached CMMS work.

We appreciate your continued partnership and remain committed to ensuring efficient and compliant operations at the Adelanto Wastewater Treatment Plant. Please do not hesitate to reach out should you have any questions or require further details.

We look forward to discussing this report further at our next meeting.

Best regards,
Dave Kachelski

Executive Summary
Adelanto WWTP received 103,668 million gallons of raw sewage and successfully treated 103,668 million gallons during the month of December 2025, making the total treated amount of water recycled at the Adelanto WWTP about 12.258 billion gallons (since operating services began in April 2012). The characteristics of the water entering and exiting the plant last month are detailed in the section titled “Flows and Laboratory Results.” Secondary effluent from the Facility was discharged to percolation basins 1, 4, 5, & 9 per the discharge requirements for this period. No flow was diverted to VVWRA.

During December, the daily influent flow recorded an average of 3.344 million gallons per day.

Effluent flow is calculated by subtracting the treated flow minus the Waste Activated Sludge (WAS) flow for each day and the daily calculated effluent flow averaged 3.267 million gallons per day.

Throughout the month, PERC Water’s Asset Management Team performed daily process control sampling and analysis, trend analysis, equipment verification checks, compliance sampling, housekeeping, process adjustments, and solids processing. Please see “Plant Staffing” for details about PERC Water’s dedicated Adelanto WWTP team. There were no injuries, accidents, facility tours, regulatory meetings, odor complaints, or security issues this month. No flow was diverted to VVWRA.

No violations or injuries to report for the month of December 2025 155

Well MW-4 was located and sampled during this monitoring event.

All other groundwater monitoring wells were gauged and sampled as outlined in the WDR permit. Field data was recorded onto Project Status Reports and included in Appendix B.

Well MW-1 was replaced with well MW-1A and therefore MW-1 was not sampled.

Gauging data from well BZ-01 was coordinated with the adjacent former George Air Force Base.

The gauging of well BZ-01 was conducted on an alternate date (November 11, 2025).

Groundwater gauging summary for BZ-01 is included in Appendix C.

Site Description
The subject site is located in the northern portion of the City of Adelanto, approximately 2,500 feet east of US Highway 395, northeast of the intersection of Auburn Avenue and Jonathan Street, in the County of San Bernardino. A site vicinity map is included as Figure 1. The Southern California Logistics Airport (former George Air Force Base) lies approximately, 0.5 miles due east of the site. The site lies at an elevation of approximately 2,842 feet above mean sea level. With the exception of the Shadow Mountain area north of Adelanto, topography across the area is relatively flat and featureless, sloping gently towards the north-northeast at an average gradient of approximately 25 feet per mile. The only surface water drainage of any observable significance is close proximity to the site is a desert wash that extends in a northwestsoutheast manner about 2,000 feet due west and 3,000 feet due south of the site. This drainage joins Fremont Wash approximately 3.5 miles northwest of the site, and from there finds confluence with the Mojave River near the own of Helendale, approximately 11 miles northeast of the site.

The facility began treating wastewater in 1998 with an initial design capacity of 1.5 MGD. Treated effluent is discharged into a series of excavated percolation ponds along the northern and central portions of the site. Since 1998, the amount of effluent required to be handled by the facility has risen significantly. Recent improvements to the facility have resulted in the significant increase in plant capacity to 3.0 MGD, and as of March 2013, the WWTP no longer bypasses excess wastewater to the Victor Valley Wastewater Reclamation Authority (VVWRA) treatment plant, but handles, treats, and disposes of all waste it receives onsite.

The facility includes ten (10) groundwater monitoring wells (MW-1A, MW-2 through MW-10) that are used to monitor groundwater conditions surrounding the facility.

Groundwater monitoring well locations are depicted on Figure 2.

Well installation activities were conducted in 1998 for wells MW-2 and MW-3, 2011 for wells MW-7, MW-8, and MW-9. Due to the extended screen length in existing well MW1, well MW-1A was installed as a replacement well for well MW-1 to provide a shallower screen depth that were more consistent with wells MW-2 through MW-10.

Current semi-annual groundwater monitoring and sampling only includes wells MW-1A, MW-2 through MW-10. The wells are sampled every April and October as outlined in the WDR permit. A summary of the completion detail is included as Table 1. 224
Geologic and Hydrogeologic Settings
The subject site is located in the high desert region of the Mojave Desert of southern California. The area is situated on a broad erosional plain of coalescing alluvial fans.

Geologic units Characteristic of alluvial fans include interbedded deposits of clastic sediments and eroded debris laid down in high energy fluvial systems such as braided stream channels and flood events typical of desert environments. Subsurface materials included interbedded layers of sands, silts, gravels and cobbles, and other varying mixtures. Clay layers, calcareous soils (cacliche), and evaporite deposits can occur but are generally of limited thickness and areal extent.

The subject site is part of the Mojave River Valley Groundwater Basin (which includes upper, middle and lower sub-basins), and are managed by the Mojave Water Agency.

Regional groundwater flow direction are to the north-northeast toward the Mojave River.

According to the California Department of Water Resources, there are two distinct waterbearing units present in the area of the subject site1 . The first is described as a Pleistocene
and younger floodplain unit (called the “Floodplain Unit”) that extends 50 to 200 feet deep in the Basin. The other is described as a Pliocene and younger fan unit (called the “Fan Unit”) that includes unconsolidated to partially consolidated alluvial fan deposits up to 1,000 feet thick. The available geologic information suggests that the site is primarily underlain by the Fan Unit.

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGING AND SAMPLING Introduction
The Low-Flow purging and sampling technique is the preferred procedure for groundwater sampling under a wide range of hydrogeologic settings. The objective of low-flow/minimal drawdown purging is to obtain a sample that is most representative of the ambient groundwater conditions near the well, taking into consideration aquifer heterogeneities and site-specific subsurface conditions, without imparting bias due to excessive pump rates or formation stress.

The Low-Flow method of purging and sampling involves using a pump to purge water at a constant low rate to achieve field parameter stabilization, while minimizing stress on the aquifer. This method has been well documented as a preferred methodology for collecting representative samples from groundwater (Low-Flow (Minimal Drawdown), Ground-Water Sampling Procedures, Puls and Barcelona, USEPA, April 1996). LowFlow purging is considered by leading researchers as superior to bailing and high-rate pumping and results in a more representative sample than the typical “three volume” well purge methodology or well evacuation.

This procedure is accomplished by measuring field parameters at periodic intervals during purging with a flow cell container. The flow cell is an inline purge cell, which will allow the sample technician to constantly monitor field water quality parameters such as temperature, pH, dissolved oxygen, and conductivity. Other techniques or containers can be used to collect samples for periodic measurements, provided that periodic and representative samples can be collected.

The following sections provide a general discussion on each aspect of the Low-Flow procedure with bulleted items being procedural steps.

Equipment
Dedicated pumps are ideal for low flow purging. Sites that have observation wells without dedicated pumps will require the use of portable (non-dedicated) pumps (bailers cannot to be used for low-flow purging). The sampling team should have all equipment necessary for purging and sampling wells at low flow rates. Other equipment may include:
o Water Level Tape or other water level measuring device; o Flow cell to monitor field parameters;
o Calibrated purge water container;
o Dedicated pump system or disposable sample tubing (for non-dedicated pumps); and
o Field Meters for pH, Temperature, Dissolved Oxygen, and Conductivity/Specific Conductance.

Prior to each sampling event the field probes will be calibrated in accordance with the owner’s manual provided and the site-specific sampling plan. Field probes should be checked for drift every four hours or at the end of the day at a minimum. 227

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 1 It is important to identify the range, resolution and accuracy of the instruments used to determine if the selected stabilization criteria can be measured. If the instruments available cannot accurately measure the stabilization criteria above, consult with the regulatory program manager to determine if different criteria values would be appropriate for your sampling program.

Decontamination
Sites that have observation wells without dedicated pumps will require the use of nondedicated pumps. All non-dedicated equipment used during the purging and sampling process must be decontaminated prior to each use, including tubing, unless it is disposable):
o Downhole equipment, such as a water level indicator, is to be triple-rinsed between well locations.
o Discard disposable polyethylene tubing used with non dedicated pumps after use at each well.

Sample bottles will be provided and properly prepared by the analytical laboratory scheduled to perform the analysis. No cleaning or preparation of sampling bottles by field personal will be performed.

Purge Volumes and Monitoring Frequency
Low-flow purging does not require the calculation of the water volume in the well, since purging is based solely on indicator parameter stabilization. Rather, the volume of the pump and discharge tubing are necessary for making calculations needed to determine field measurement frequency and/or the minimum purge (“passive”) sampling system purge volume. Pump chamber or bladder volumes can be obtained from the manufacturer. Volumes of the sample tubing can be calculated or taken from the table below.

Discharge Tubing Volumes
Tubing Diameter Volume/foot
1/2" OD/3/8” ID 20 ml
3/8” OD/1/4” ID 10 ml
1/4" OD/1/8” ID 5 ml
Well casing volumes should only be calculated if required by Permit or State Regulation and recorded on field information forms. In addition, well casing volumes may be needed in any case where parameter stabilization is not achieved after a three-casingvolume purge (see below).

Sampling equipment volumes are calculated or recorded for use in determining the frequency of field measurements. Depending on the equipment configuration, calculate and record the volume of the pump and sample tubing using the methodology described 228

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 2 above (the volumes are typically converted to liters). The frequency of field readings is based on the time required to purge at least one volume of the pump and tubing system. For example, a pump and tubing volume of 500-ml purged at a rate of 250 ml/minute will be purged in two minutes; readings should be at least two minutes apart.

In any case, it is important to ensure that the field parameters are measured on independent samples of water.

Purge Rates
The objective of the purging process is to remove sufficient water from within the well screen zone to result in a sample that is representative of actual aquifer conditions adjacent to the well. The sampling pump or pump intake should be located within the well screen. This pump location is already established for dedicated pumps. For nondedicated pumps, the intake is placed within the screened interval, typically in the center of the screen. If the water column in the screen is shorter than the overall screen length, the pump should be placed lower in the screen but no lower than about 6-12 inches from the bottom of the screen to avoid picking up any settled solids in the well.

A low pumping rate (typically less than 1,000 ml/min) is used to minimize drawdown within the well and formation and mobilization of formation solids. Lower flow rates may be required during sampling. Flow rate is determined by measuring the time it takes to fill a calibrated container, or by measuring the volume of one pump discharge cycle and multiplying this volume by the number of cycles per minute (e.g., 125 ml/cycle x 4 CPM = 500 ml/min). Drawdown is monitored by measuring the water level below the top of the well casing with a water level indicator or similar device (e.g. transducer) while pumping. Drawdown will be stabilized during purging. Flow rates and drawdown are recorded on a field log, field data form or with a data logger. o Measure water levels prior to initiating purging;
o Calculate well volumes, if required by permit;
o Calculate sampling system volume and determine indicator parameter measurement frequency;
o Lower water level meter probe to 1-2 feet below static water level; o Connect the flow cell to the discharge tube from the pump; o Begin purge at a rate of 100-200 ml/min (or at a rate determined from prior events);
o Check drawdown with a water level tape while pumping; o If drawdown stabilizes quickly, increase the pumping rate in increments of 100 ml/min until drawdown increases, then reduce the rate slightly after a few minutes to achieve a stable pumping water level;
o If the water level continues to drop, reduce purge rate by 100 ml/min increments until the water level stabilizes;
o Once water level stabilization is achieved, proceed to indicator parameter stabilization.
229

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 3 Parameter Stabilization
Parameter stabilization ensures that the well is adequately purged and sampled groundwater is representative of formation water. In order to determine when a well has been adequately purged, samplers should:
o Monitor pH, specific conductance, and dissolved oxygen of the ground water removed during purging;
o Observe and record the water level drawdown; and
o Record the purge rate and note the volume of water removed if required by guidance or permit.

A well is adequately purged when the pH, specific conductance, and dissolved oxygen stabilize. Stabilization occurs as follows:
pH: +/- 0.2 pH units
Conductance: +/- 5 % of reading value
Dissolved oxygen: +/- 10.0% or 0.2 mg/L, whichever is greater.

Temperature is not a reliable indicator of stabilization, being affected by ambient temperature at the well head, sunlight, and some sampling devices such as electric pumps. Temperature is typically measured to provide correction for temperature dependent parameters (e.g., DO % saturation, pH, and specific conductance).

While turbidity is not a direct measurement of water chemistry and is not used as an indicator parameter of stabilization, it is useful to support data from metals analyses. To avoid artifacts in sample analysis, turbidity should be as low as possible when samples are taken. Turbidity should be measured at least three times, once when purging is initiated, again after the water level in the well stabilizes, and again when the water chemistry indicator parameters being measured are stable. Turbidity should also be measured any time the pumping rate is increased or the water level in the well drops noticeably. If the initial turbidity reading is high (>50 NTU) and the second reading is not significantly lower, the pump rate should be reduced. The turbidity value measured prior to sampling will be recorded. If this value exceeds 50 NTU, procedures should be reviewed and the source of the elevated turbidity determined.

Sampling
Wells should be sampled immediately upon completion of purging operations. Once the water level stabilizes, the purge rate should remain constant during low-flow sampling (generally less than 500 ml/min). For VOCs, lower sampling rates (100 - 200 milliliters/minute) may be required.
o Record field parameters prior to sampling;
o Record depth to water levels prior to sampling (note if the well has not stabilized). 230

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 4 o Record the flow rate determined using a calibrated measuring device; o Disconnect the flow cell other equipment from the pump discharge tube; o Collect samples from the pump discharge tube
o Collect large volume samples first (e.g.,1 liter bottles), then VOC samples, and any filtered samples last;
If, after three well volumes have been removed, the chemical parameters have not stabilized according to the above criteria, the sampling team may elect to collect a sample. The conditions of sampling should be noted in the field log or field information form.

Low Yield Formations
In some situations, even with very slow purge rates, the well drawdown may not stabilize. In this case, sampling the water within the well screen zone provides the best opportunity to determine the formation water chemistry, as well evacuation can greatly affect sample chemistry through changes in dissolved gas levels, dissolved metals and VOCs.

Attempts should be made to avoid purging wells to dryness. This can usually be accomplished by slowing the purge rate. If the well is evacuated during the purging procedures shown above, the sample may be collected as soon as a sufficient volume of water has recovered in the well. If the well goes dry repeatedly (i.e. over multiple monitoring events) prior to sampling, then a minimum purge or “passive” sampling approach should be used in lieu of well evacuation.

Minimum Purge (“Passive”) Sampling
For wells that cannot achieve a stabilized water level and purge dry even at very low pumping rates, an alternative to the traditional evacuation approach is to use minimum purge (sometimes called “passive”) sampling techniques to avoid the pitfalls of well evacuation and obtain a better estimation of the formation water quality. Sampling the water present in the screen zone provides the greatest chance of obtaining samples with minimal alteration of the chemistry. Although the low movement rate of the ground water in the screen provides only a limited exchange, avoiding the alteration caused by the factors mentioned above is really the best alternative.

The minimum purge approach requires the removal of the smallest possible purge volume prior to sampling, generally limited to the volume of the sampling system. The sampling system volume is minimized by using very small diameter tubing and the smallest possible pump chamber volume. Plastic tubing should have sufficient wall thickness to minimize the potential for oxygen transfer through the tubing when pumping at very low flow rates. After purging 1-3 volumes of the sampling system, samples are taken from the subsequent water pumped. Since minimum purge sampling requires the minimum possible disturbance to the water column and surrounding formation, dedicated sampling systems are required for this approach. 231

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 5 The pumping rates used for minimum purge sampling are much lower than for low-flow purging, generally 100 ml/minute or less. Drawdown is expected, since it cannot be avoided; however, it is still advisable to pump at the lowest possible rate to limit drawdown to the minimum possible. Monitoring indicator parameters for stability is not part of this approach, since the intention is not to purge until stabilization of these measurements. The pH, specific conductance and turbidity or any other required field parameters should be measured during collection of the sample from the recovered volume. Regulatory approval should be obtained prior to collecting a sample using this method.

Field Records
Field information must be recorded during purging and sampling. At a minimum, the following information should be included in the field forms for each groundwater monitoring well.
o Purge Information (pumping rate, purge volume if required); o Equipment Specifications (pump type, filter type and pore size if used); o Well Data (depth to water, total depth, groundwater elevation); o Field Measurements during purging and at the time of sample collection; and o General weather conditions or other comments
This data is to be recorded on field forms and/or in a data logger.

Other Technical Issues
The following are other technical issues addressed as follows by the facility:
o Dedicated pump intakes are generally set at the middle of the screen. Where water levels have dropped due to drought conditions, the sampling team may lower the pump in order to obtain sufficient sample.
o For wells installed in bedrock, packers are only required to seal off the zone of interest if the bedrock has been determined to be competent (e.g. is not highly fractured).
o The flow cell system does not require decontamination between wells, because the act of purging removes any liquids from other wells and because sampling takes place upstream of the flow cell and only after disconnecting the pump discharge tubing.

City of Adelanto 1 Woodard & Curran, Inc.

Adelanto Water MOR December 2025 December 2025

1. EXECUTIVE SUMMARY
The following operational overview highlights the successful operations of the City’s water system from December 1 – December 31, 2025. With more than 100 days of continuous operations completed, Woodard & Curran has moved beyond the transition phase and into stable, fully integrated operations.

The focus has shifted to operational excellence, preventative maintenance, staff development, and system optimization, supported by ongoing safety audits and the continued implementation of the Enterprise Asset Management System (EAMS).

Health & Safety
The safety of our employees, City staff, contractors, and ratepayers remains Woodard & Curran’s highest priority. We are pleased to report that there were no OSHA-recordable or lost-time incidents during this reporting period, and we have now reached 108 days without a safety incident.

Regulatory Compliance
Woodard & Curran met regulatory compliance standards for the City’s public water system in accordance with regulations from the Division of Drinking Water.

Capital Improvement Projects
Woodard & Curran has reviewed the previous O&M firm’s CIP recommendations and is engaged in discussions with the City’s Engineering Department. We will continue to partner with the City’s Engineering Department and position the city to implement necessary capital improvement projects.

Budget
Adelanto’s budget execution through December demonstrates strong fiscal discipline and efficient resource utilization. Spending remains consistently below budgeted levels, primarily due to reduced labor and supply-related costs. Although minor overages exist in discretionary expense categories, they are offset by substantial savings elsewhere. Overall, financial management appears efficient and conservative, maintaining healthy budget variances.

Adelanto Water MOR December 2025 December 2025

2. HEALTH & SAFETY
December: Hearing Protection
At Woodard & Curran, employee safety is our top priority. Protecting our hearing is an important part of maintaining a safe and healthy workplace. Noise-induced hearing loss can develop gradually over time or result from short-term exposure to loud equipment, and the damage is often permanent. Because hearing loss may not be immediately noticeable, consistent use of hearing protection is essential to prevent longterm injury and ensure employees go home safely each day.

Water department staff may be exposed to elevated noise levels during routine operations and maintenance activities. Common noise sources include pumps, motors, compressors, treatment processes, vehicles, heavy equipment, and power tools. Noise hazards can be greater during extended work periods or when working in enclosed areas such as pump stations, treatment facilities, and mechanical rooms.

By staying aware of noise hazards and using hearing protection during daily tasks, Woodard & Curran staff support a safe work environment and reinforce our commitment to safety-first operations.

SPARKS Program Overview
The SPARKS Program is an O&M safety initiative designed to recognize employees who demonstrate a strong personal commitment to safety and consistently work with their peers to maintain a safe and healthy work environment. Each year, staff are evaluated on established safety goals—such as maintaining zero OSHA-recordable incidents, completing required safety training, attending monthly safety meetings, and fulfilling all annual H&S tasks. When individuals and teams meet these expectations, they become eligible for an annual incentive, with increased rewards for consecutive years of achievement. The program reinforces daily safe-work habits, strengthens teamwork, and encourages proactive communication about safety, all of which contributes to our long-term safety performance.

Staff Participation
This year, participation in the SPARKS Program continues to grow, with all staff now actively involved in meeting the required safety goals. Employees are engaging in monthly training, collaborating more effectively on hazard identification, and supporting one another in maintaining compliance with program requirements. The increased participation reflects strong team commitment and helps ensure that everyone has a role in sustaining a safe workplace. As staff continue to meet their annual safety objectives, they remain eligible for SPARKS incentives—further reinforcing the positive safety behaviors the program was designed to promote.

4. WATER PRODUCTION AND TREATMENT

4.1 Operations
During this reporting period, the City of Adelanto produced 49.26 million gallons of water from six active wells. One of these wells (8G2) disinfects water at the wellhead prior to transmission to one of six water storage tanks. Four of these wells (1G, 3G, 4G, 8G) send water to the Water Treatment Plant (WTP) to treat iron and manganese. This treatment process consists of Iron and Manganese Filtration. Following treatment for iron and manganese, the WTP’s effluent is blended with water from the other wells and purchased water from Mojave Water Agency and the City of Victorville (as needed) in the City’s water storage tanks and distribution system. In December, 66.97 million gallons were purchased from MWA R3 connection.

During this reporting period (December), the WTP treated 41.13 million gallons of raw water, and all samples were within acceptable ranges for iron, manganese, and other contaminants. In addition to weekly samples sent to Geo Monitor, Woodard & Curran’s staff takes daily samples to maintain process control, and these results are found in Table 4-1.

DATE: January 28, 2026
TO: Honorable Mayor and City Council Members
FROM: Jessie Flores, City Manager
BY: Virginia Velis, Executive Assistant/Deputy City Clerk SUBJECT: CONSIDERATION OF A RESOLUTION APPROVING THE CITY’S

COMMUNITY DEVELOPMENT BLOCK GRANT PROGRAM FOR FISCAL
YEAR 2026-27
STAFF RECOMMENDATION:

1. Open the public hearing and receive public testimony; and

2. Adopt Resolution No. 26-01 authorizing the City’s Community Development Block Grant (CDBG) Program for Fiscal Year 2026–27.

BACKGROUND:

The primary national objectives of the Federal Community Development Block Grant (CDBG) Program are to support activities that benefit low- and moderate-income persons and/or eliminate slum and blight conditions within the City. Federal regulations require that at least seventy percent (70%) of CDBG funds be expended on activities benefiting low- and moderateincome individuals.

The U.S. Department of Housing and Urban Development (HUD) administers the CDBG Program and establishes program regulations. Cities with populations under 50,000 do not receive CDBG funding directly from HUD but instead participate in their respective counties. The City of Adelanto receives CDBG funds as a participating city through the County of San Bernardino Community Development and Housing Department (CDH).

CDH has notified the City that the estimated CDBG allocation for Fiscal Year (FY) 2026–27 is $174,788, representing a decrease of $126,401 from the prior year allocation of $301,189.

Allocations are based on a federally established formula that considers population, poverty level, and overcrowding. Final allocation amounts may vary slightly and are typically confirmed by HUD 269
in the spring prior to the start of July 1 of the new program year.

A resolution approving the City’s use of CDBG funds must be submitted to CDH by February 12, 2026. Funds will become available for expenditure beginning July 1, 2026.

ELIGIBLE ACTIVITIES FOR FUNDING:

Way Street Rehabilitation
The proposed project is not eligible for CDBG funding because the segment of Chamberlain Way identified in the application functions as a connector roadway and major travel route, rather than a local residential street. The roadway provides through-access between Highway 395 and multiple alternate routes serving broader traffic circulation, and is not limited to serving a defined residential neighborhood. As a result, the project primarily benefits the general motoring public rather than directly benefiting low- and moderateincome residents within a specific service area. CDBG funds may not be used for improvements that serve general community-wide traffic needs or major thoroughfares, and the application does not demonstrate that the proposed improvements are confined to a neighborhood-level street serving residential properties. 0 $ 350,000 No

SUBJECT: REJECTION OF ALL BIDS FOR THE SENECA ROAD REHABILITATION PROJECT STAFF RECOMMENDATION:

Staff recommends that the City Council reject all bids received for the Seneca Road Rehabilitation Project pursuant to the City’s bid documents and the California Public Contract Code, direct staff to revise the plans and specifications and re-bid the project.

BACKGROUND:

The Seneca Road Rehabilitation Project is intended to rehabilitate existing pavement conditions to improve roadway safety and drivability. The project scope includes asphalt concrete grinding and overlay, localized pavement repairs, and associated roadway improvements. Plans and specifications were prepared by KEC Engineers, Inc. in coordination with City Engineering staff.

A Notice Inviting Bids was issued, and sealed bids were publicly opened on December 9, 2025. Ten (10) bids were received and reviewed for responsiveness and compliance with the contract requirements.

Following bid opening and further engineering evaluation, staff identified the need to modify the plans and specifications. incorporate additional scope and design refinements necessary to address project requirements and field conditions. These revisions represent quantity changes and potentially minor changes to the standards that could reasonably impact bid pricing and competition.

Pursuant to the California Public Contract Code and the City’s bid documents, the City reserves the right to reject any or all bids when it is determined to be in the best interest of the City. Rejecting all bids and rebidding the project with revised plans ensures fairness, transparency, and full and open competition, and avoids the potential risks associated with awarding a contract and subsequently modifying the scope through change orders.

FISCAL IMPACT:

No immediate fiscal impact. The project is anticipated to be funded using SB-1 Rehabilitation Funds, with final costs determined upon rebid.
