6 The Sewage Spill Field Report form in Attachment A can be used by the Wastewater Maintenance Supervisor or designated backup person to capture the relevant information needed to respond to a report of a possible sewage spill and help initiate the work order assignment.
Operations Division Personnel Notifications of Possible Sewage Spills Possible and actual sewage spills detected by maintenance personnel during their regular duties are reported immediately to the Wastewater Maintenance Supervisor or designated backup.
Personnel on-site observing the sewage spill should begin efforts to contain and minimize its effects, as further described in subsection 2.5 below.
2.2 First Responder Responsibilities
Based on the information provided during the notification of a possible sewage spill, the Wastewater Maintenance Supervisor or the designated back-up person shall proceed to the sewage spill location to assess the cause and extent of the sewage spill. The City staff person who arrives first at the location is considered the First Responder. The First Responder will determine whether to direct a wastewater crew, other City personnel, and/or approved contractors to the sewage spill location if the spill cannot be fully contained or recovered, or it has reached public waters. The information obtained by the First Responder during the initial notification of a possible sewage spill may warrant the First Responder, in their best professional judgment, to immediately dispatch crews or other City personnel to the sewage spill location before proceeding to the reported sewage spill location.
The First Responder is responsible for protecting the health and safety of the public by mitigating the impacts of the sewage spill to the maximum extent possible. Areas where public contact with sewage is possible shall be isolated using barricades, signs, or other effective means. Upon determining the sewage spill originated in the City’s jurisdiction, the First Responder will perform the following:
Determine the cause of the sewage spill, e.g., sewer line blockage, or pipeline break, etc.; Identify and request, if necessary, additional personnel, materials, and equipment necessary to minimize, contain, or isolate the impact of the sewage spill; Control public access to affected area; and
Implement efforts to stop the spill.
If the First Responder determines the sewage spill is not within the City’s jurisdiction, the City should notify the responsible agency to respond to the spill. If the sewage spill poses an imminent danger to the public, public health, property, or public waterways of the United States, the First Responder should take prudent emergency actions to mitigate the sewage spill until the responsible agency’s staff arrives.
7 Figure 1
Process for Alerting Staff of a Possible Sanitary Sewer Overflow If the First Responder cannot locate the sewage spill or the reported problem, he/she shall attempt to obtain additional information from the initial caller or Police Dispatch Operator to clarify reported data and to locate the problem. If the sewage spill or reported problem still cannot be located, the First Responder shall check the system for normal flows, advise dispatch of the status, and prepare the final field report.
2.3 Dispatch of Crew(s) to Sewage Spill Location
Failure of any element within the wastewater collection system that threatens to cause or causes a sewage spill triggers an immediate response to isolate and correct the problem. City Operations Division crews and equipment are stationed at the City’s Public Works Yard, from where they are dispatched. The equipment is available 24 hours a day, and staff are placed “on-call” on a rotational schedule to respond to any site of a reported sewage spill. Additional City maintenance personnel are “on call” if additional crews are necessary. Attachment B contains the names, contact information, and on-call schedule for City staff.
All employees dispatched to a sewage spill location shall proceed immediately to the site. All necessary precautionary measures to ensure staff safety shall be in place. Overflows within the Discovery and Notification

Photos
Responders must take several photos of the spill location and downstream spill path, capture, and/or result, and take photos from several angles to ensure the spill is documented.
2.4 Requesting Additional Resources
If the First Responder decides that notifying additional staff beyond the “on-call” sewage spill response crews is needed and/or City-approved contractors are required to fully contain and recover the spill, the Wastewater Maintenance Supervisor or designated backup will mobilize the necessary resources. The City can access extra support from its own staff as well as outside oncall contractors that can be mobilized in case of an emergency or major sewage spills. The list of City-approved contractors and equipment rental vendors is provided in Attachment C.
Coordination with Stormwater Agencies
The Public Works Department of the City of La Mesa has combined sewer and storm drain resource personnel; therefore, coordination is implied.
2.5 Overflow Containment, Correction, and Clean-up
This section describes specific actions to be performed by the Operations Division staff and additional crews responding during a sewage spill. The objectives of the specific actions described in this section include:
Protect public health, the environment, and property from sewage spills and restore the surrounding area to its original condition;
Contain the sewage discharged to the maximum extent possible and prevent the discharge of sewage into surface waters;
Control traffic and crowds to limit public access by establishing perimeters and control zones with cones, barricades, sign postings, caution tape, vehicles, and/or terrain; When appropriate, promptly notify regulatory agencies of preliminary sewage spill information and potential impacts; and
Minimize the City’s exposure to any regulatory agency penalties and fines.
Under most circumstances, the City will oversee, manage, and perform the tasks necessary to effectively and adequately correct, contain, and clean up sewage spills. The City shall respond with its staff, equipment, and/or contractors. These personnel have the skill and experience to respond rapidly and in the most appropriate manner. An emergency response's critical importance is ensuring that the temporary actions necessary to divert flows and fix the problem do not produce a problem elsewhere in the system. If the matter is not handled correctly, subsequent sewer system back-ups may occur, creating other sewage spills.
Initial Containment Measures
The following are initial measures to contain the sewage spill and recover, where possible, sewage that has already spilled to minimize impact to the public or environment. The City crew responding to the incident shall:
9 1. Determine the immediate destination of the spill (e.g., street curb gutter, storm drain, drainage channel, creek bed, body of water, etc.);
2. Take immediate steps to contain and recover the spill (e.g., block storm drain, recover sewage with a vacuum truck, dig or construct a containment pond, divert flow into a downstream manhole, etc.).
3. Identify and request, if necessary, assistance or additional City and/or Contractor resources (materials and equipment) to contain or isolate the spill;
4. Large spills greater than 10,000 gallons include all the above, a requirement to build additional emergency containment areas downstream of the sewage spill, if possible, and initiating an access plan into storm or flood control channels to contain sewage spills that enter the storm drain system.
Additional Measures for Prolonged Overflow Conditions
In the event of a prolonged sewer line blockage or collapse, the responding City crew shall set up a portable bypass pumping system around the obstruction, continuously or periodically monitor the bypass operation, and carry out emergency repairs to stop the spill. Table 1 can be used as a guide to select the appropriate pump.

8 X 8 1,600 15-inch diameter
10 X 10 2,800 18-inch diameter
Correction of Sewage Spill Cause
Once the sewage spill has been contained and the cause determined, efforts to correct the cause of the sewage spill should commence. These efforts may involve, but not be limited to, removing the pipe blockage by flushing or rodding and repairing a damaged pipeline or manhole. Care must be taken to prevent additional sewage spills from occurring as a result of the corrective action taken to resolve the identified problem.
Clean-up
All sewage spill sites must be thoroughly cleaned as soon as possible after a spill. No readily identifiable residue (e.g., sewage solids, papers, plastics, etc.) is to remain. Clean-up of all sewage spills will be handled according to the following procedures:
The sewage spill site must be secured to prevent contact by members of the public until the site has been thoroughly cleaned;
Where practical, the area shall be thoroughly flushed and cleaned of any sewage or washdown water using a high-pressure water hose or Vactor truck; wash-down water shall be
10 contained and recovered; solids and debris shall be flushed, swept, raked, or manually removed, and hauled away for proper disposal;
Where appropriate (typically in areas with hard surfaces), areas that were in contact with the sewage shall be disinfected and deodorized; proper contact time for proper disinfection must be ensured;
Where sewage resulted in ponding, the pond must be pumped dry and the residue removed and disposed of properly;
If sewage discharged into a body of water that may contain fish or other aquatic life, disinfection will not be performed, and the appropriate agency will be contacted; and Where appropriate, disinfect and deodorize the sewage spill site using liquid bleach, commercial sanitizers (such as HTH®), etc.
2.6 Traffic and Crowd Control
The purpose of traffic and crowd control is to restrict public access to areas that could be affected by unpermitted sewage discharges. The following traffic and crowd control recommendations can serve as a guide for different types of sewage spills.
Small sewage spill (Up to 1,000 gallons)
Set up cones to direct traffic away from the spill area; and Use City personnel to control traffic and pedestrians.
Medium sewage spill (1,000 to 10,000 gallons)
Perform lane closures as necessary;
Place proper signage for any lane closures and contaminated area signs; Close affected entrances or exits from public and private facilities; and Place caution tape and barricades to protect pedestrians from the contaminated area.
Large sewage spill (greater than 10,000 gallons)
Assess the spill situation;
Inform City Police Department of any law enforcement assistance necessary for roadway closures and traffic control;
Delegate responsibility to County Department of Environmental Health Quality for informing the public of hazards;
Place signage to inform the public of potential hazards to public health and safety; and Block public access to the area using barricades, cones, and caution tape.
2.7 Preliminary Assessment of Damage to Private and Public Property
Initial assessment of the sewage spill site is performed by the First Responder, who may be the Wastewater Maintenance Supervisor, the designated back-up person, or other City staff. The First Responder will determine whether the sewage spill originated from the City’s collection system, a private business, or a residence. Once the source of the sewage spill is determined, containment and cleanup procedures are executed, and a Sewer Spill Field Report (see Attachment A) will be completed.
11 Public Source Sewage Spill
If it is determined that the source of the sewage spill is from the City’s wastewater collection system, containment and cleanup procedures are executed to prevent the sewage spill from reaching adjacent private properties, local water bodies, and the storm drain system. Once the sewage spill is contained and cleaned, proper documentation utilizing the appropriate forms will be completed.
If it is determined that the sewage spill has reached a private residence or business, the sewage spill is reported to the City’s Risk Management personnel prior to Wastewater Maintenance personnel leaving the site. A Damage Report to Private Property (see Attachment D) is completed and forwarded with the Sewer Spill Field Report to the City’s Risk Management. Photographs and/or video footage should be taken of the spill and the area impacted by the sewage spill.
Photographs and/or video footage should be filed with the Sewer Spill Field Report.
Private Source Sewage Spill
If it is determined that the source of the sewage spill is from a private property, the First Responder and crew will use discretion in assisting the property owner/occupant as reasonably as they can.
City staff are cautioned that the City and the Operations Division may be liable for further damages inflicted on private property during such assistance. If City staff enter private property, it should be with the explicit permission of the owner/occupant of the property. The City crew should not enter private property to assess damage. Staff is directed to take appropriate photographs and video footage, if possible, of the surrounding and impacted area to document the nature and extent of the impacts thoroughly. Photographs and/or video footage should be filed with the Sewer Spill Field Report.
2.8 Notification Requirements
A sewage spill's volume, impact, and location determine the notifications required to comply with City and regulatory requirements. Table 2 summarizes the officials and agencies who should be informed of a sewage spill as soon as practicable, without impeding containment or other emergency response measures. Attachment B lists the specific names and numbers of the individuals holding these positions. The City is not required to send reports to the SDRWQCB; this reporting is now achieved using the web-based online sewage spill reporting system, CIWQS, which is further described in Chapter 4.0 below.
2.9 Regulatory Agency Notification Plan
The Regulatory Agency Notification Plan establishes procedures that the City will follow to provide formal notice to the SDRWQCB, Environmental Protection Agency (EPA), Department of Environmental Health Division of San Diego County, and other City agencies as necessary in the event of a sewage spill. Written notification, when required, shall be made within five (5) business days.

Initial Notification
In the event of a significant spill (any sewage spill greater than 10,000 gallons per day), the City must notify Federal and State Agency representatives no later than 2 hours of becoming aware of the spill. Table 2-2 identifies who should be notified and when based on the type and volume of sewage spill. The initial and any updated spill reports will then be faxed or mailed to the various agencies as identified in the Sewage Spill Notification List, provided in Attachment B. The supervisor in charge will contact the regulatory agencies.
Secondary Notification
After the sewage spill notifications (Table 2) have been made, the City will contact the other regulatory agencies using the Sewage Spill Notification List (Attachment B) as required and other impacted parties if there has been a spill.
2.10 Monitoring and Mitigation
The First Responder who confirmed the sewage spill must ensure that the provisions of this SERP and other directives are met. City staff shall assess the impacts following a sewage spill.
Appropriate mitigation and monitoring measures shall be implemented following the assessment to monitor the site for potential future sewage spills and to prevent sewage spills from re-occurring.
For sewage spills that reach surface waters, the City must conduct the following activities:
Obtain water quality samples.
Gather samples upstream and downstream of any location where the sewage spill reached surface water.
Log the sample location, time, and water temperature on the chain of custody form. Create a map of the sample locations so that follow-up testing can be performed.
13 Collect samples at the location where the sewage spill entered the water. When taking the sample, submerge the bottle below the surface of the water with the cap on. Once the bottle is under the surface, remove the cap and fill the bottle. Gloves should be worn while sampling to avoid infecting any open wounds.
Analyze the sample for at least the following constituents:
o Ammonia Nitrogen;
o Biochemical Oxygen Demand (BOD);
o Dissolved Oxygen (DO);
o Total Fecal Coliform;
o Total Suspended Solids (TSS); and
o Additional sampling requirements as imposed by the SDRWQCB.
2.11 Sewage Spill Documentation
Documenting sewage spills and their causes provides information for:
Management for performance measurement and decision-making; Regulators to meet established reporting requirements; Planning future maintenance and repair activities;
Engineering determinations regarding capacity, rehabilitation, or replacement; and Reference for historical performance or claims.
The First Responder shall ensure the sewage spill is properly investigated and documented.
Information compiled during the investigation of the sewage spill shall be recorded on the Sewage Spill Report (Attachment A). Copies of supporting information shall be compiled. The minimum information required from the investigation is:
Cause of sewage spill;
Volume of sewage spill, including volume released and volume recovered; Location of point of discharge, including Thomas Guide map page; Ultimate destination of the sewage spill;
Impact and extent of impact;
Estimated start time of sewage spill;
Time City received notification of sewage spill;
Arrival time of crew(s) and time to correct the sewage spill; End time of sewage spill;
Water body impacted and results of bacteriological monitoring, if applicable; Actions taken to mitigate the sewage spill; and
Notifications to regulators and others.
There are various approaches to estimating sewage spill volumes. Attachment E guides estimating the volume of sewage that escaped from the wastewater collection system and the amount of sewage recovered.
The City will follow up, in person or by telephone, with the person(s) initially reporting the sewage spill. The cause of the sewage spill and its resolution should be disclosed.
14 3 Public Advisory of Sewage Contamination
Procedures
This chapter describes the action the City must take to limit public access to surface waters and other areas potentially impacted by sewage spills from the wastewater collection system.
The City is primarily responsible for determining when to post notices of polluted surface waters or ground surfaces resulting from uncontrolled wastewater discharges from its facilities. The County Department of Environmental Health Quality may also make a determination and direct the City to post notices. The postings do not necessarily prohibit the use of recreational areas, unless posted otherwise, but provide a warning of potential public health risks due to sewage contamination.
Notices shall be posted as soon as practicable following the initial response to the spill. Signs should be posted on either side of the entry point where sewage entered the body of water or public facility, and the nearest public access point to that body of water or public facility. Examples of signs are included in Attachment F.
Staff shall regularly inspect the posted notices and replace any missing or damaged warning signs. Posted notices shall not be removed until it is determined that the threat to public health and safety is eliminated or at the direction of the County Department of Environmental Health Quality.
Should additional notification of sewage contamination be deemed necessary, City staff shall, in cooperation with the City’s public information officer, provide further notices through the use of pre-scripted notices made available to the printed or electronic news media for immediate publication or airing, or by other measures, such as door hangers.
15 4 Sewage Spill Monitoring and Reporting
Requirements
City staff shall monitor and report sewage spills regardless of size and recovery originating from the City’s wastewater collection system. The City must also report any known sewage spills on private property from private laterals. This chapter details the reporting procedures necessary to comply with SWRCB and City requirements.
4.1 Sewage Spill Identification, Tracking, and Logging
A work order must be created to track and monitor each sewage spill event. Using a completed Sewage Spill Field Report form (Attachment A), the Wastewater Maintenance Supervisor can create or update the work order and enter the necessary data. All forms, documentation, and monitoring results should be kept with the work order.
4.2 Sewage Spill Category Classification
Sewage spills are categorized into three types:
Category 1 Sewage Spills: All discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:
Reach surface water and/or drainage channel tributary to a surface water; or Reach a Municipal Separate Storm Sewer System (MS4) and are not fully captured and returned to the sanitary sewer system or otherwise captured and disposed of properly.
Any volume of wastewater not recovered from the MS4 is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or ground water infiltration basin (e.g., infiltration pit, percolation pond).
Category 2 Sewage Spills: Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee’s sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel, or a MS4 unless the entire sewage spill discharged to the storm drain system is fully recovered and disposed properly.
Category 3 Sewage Spills: All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition.
Private Lateral Sewage Discharge (PLSD): Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or other private sewer assets. PLSDs that the enrollee becomes aware of may be voluntarily reported to the California Integrated Water Quality System (CIWQS) Online Database.
Figure 2 is a flow chart that will guide City staff in determining the category classification of a sewage spill and the necessary reporting requirements.
4.3 Online Reporting Requirements
The WDRs require that the City report sewage spills using the California Integrated Water Quality System (CIWQS) Online Database per the current Order 2022-0103-DWQ and associated 2022 MRP.
16 Reporting Authority and Access
At a minimum, the City must have one (1) Legally Responsible Official (LRO) registered with the State of California to officially sign and certify sewage spill reports submitted via the CIWQS website. The City has identified at least one additional LRO as a backup.
The City also identified Data Submitters. These are individuals registered with the State to enter sewage spill data, create and edit sewage spill reports, and review data. Data Submitters cannot certify reports. The City can identify and register as many Data Submitters as deemed necessary.
Each Agency is assigned a unique Waste Discharge Identification Number (WDID). The City of La Mesa’s number is WDID #9SSO10652. All LROs and Data Submitters receive a unique login and password. This information should be guarded and protected. If an authorized user suspects his or her login and password have been lost, stolen, or otherwise compromised, that person shall contact the SWRCB via the CIWQS help desk at 866-792-4977.
Mandatory Information to Report via CIWQS
Before finalizing and certifying a sewage spill report, specific mandatory information must be included for each sewage spill report submitted via CIWQS.
The following information is required for all Category 2 sewage spills:
1. Location of sewage spill using Global Positioning System (GPS) coordinates;
2. Regional Water Board 9;
3. San Diego County;
4. Whether the sewage spill entered a drainage channel and/or surface water;
5. Whether the sewage spill was discharged into a storm drain pipe that was not fully captured and returned to the wastewater collection system;
6. Estimated sewage spill volume in gallons;
7. Sewage spill source (e.g., manhole, cleanout, pipeline, etc.);
8. Sewage spill cause (e.g., mainline blockage, roots, grease, etc.);

Collection system telemetry records, if relied upon to document and/or estimate sewage spill volume.
20 4.5 Water Quality Monitoring Plan for Major Spills
In accordance with the Monitoring and Reporting Program (MRP) for Order 2022-0103-DWQ, the City shall implement water quality monitoring for all Category 1 Sanitary Sewer Overflows (SSOs) of 50,000 gallons or greater that reach surface waters. The purpose of the monitoring is to assess the extent and impact of the spill on receiving waters and to support any required public health notifications and environmental assessments.
The following requirements apply:
Timing of Sampling:
Water quality sampling must begin as soon as feasible, but no later than 48 hours after the City becomes aware of the SSO.
Minimum Required Analytes:
At a minimum, the City must analyze these parameters at each sampling location:
Ammonia
Total Coliform
Fecal Coliform
Enterococcus
Additional sampling parameters may be required by the SDRWQCB based on site-specific conditions.
Sampling Locations:
The City shall collect samples at the following locations, at a minimum:
1. Upstream of the point of entry to surface water (to establish background conditions)
2. Downstream of the point of entry (to assess impact)
3. At the point where the sewage spill entered the surface water Documentation and Reporting:
Water quality sampling results must be documented and included in the Sewage Spill Technical Report required for all Category 1 SSOs of 50,000 gallons or more, as described in Section 4.3.
The Sewage Spill Technical Report must be submitted to CIWQS within 45 calendar days of the end date of the sewage spill.
Quality Assurance/Quality Control (QA/QC):
All sampling and laboratory analysis shall follow applicable QA/QC procedures as outlined in Attachment C of the MRP for Order 2022-0103-DWQ, including use of State-certified laboratories and proper chain-of-custody documentation.
21 5 Training
Appropriate staff will participate in regularly scheduled training sessions to help response crews understand their responsibilities and carry out their duties. These sessions will be organized based on the latest SERP and other reference materials. They will also include hands-on field demonstrations to prepare all response personnel for anticipated situations.
City staff should be provided with an overview of the Sewer System Management Plan (SSMP) and the SERP. This will instruct staff on the SSMP, sewage spills, and necessary documentation.
Field demonstrations will be conducted to test equipment, response times, training effectiveness, resources, and staffing capabilities.
Training and event participation will be documented and maintained. The City of La Mesa has historically conducted quarterly wastewater training. All records of training attendees are kept in the City's wastewater files.

6.1 SERP Availability
The SERP will be reviewed annually to ensure that all information is updated. The amended SERP will be distributed to the appropriate staff, City Departments, and SDRWQCB and made available to the public for review. Staff shall ensure that this SERP is readily available to wastewater maintenance personnel and that said personnel are familiar with the plan and always comply with it.
6.2 Review and Update of the SERP
City staff shall maintain this SERP and amend or update it as necessary by adding new facilities or changes in the operation or maintenance of the wastewater collection system that may materially affect the potential for sewage spills. At a minimum, the plan will be reviewed annually, including updating telephone numbers and forms in the appendices and a review of procedures.
The annual review of the plan will also ensure that all its provisions are being met and implemented. City staff shall also review and amend this SERP as appropriate after any sewage spill occurrence. SERP deficiencies and updates will be addressed and modified accordingly. The plan’s performance will be routinely evaluated, reviewed, and updated.

Possible Methods for Estimating Spill Volume
Possible Methods for Estimating Spill Volume
A variety of approaches exist for the estimation of the volume of a sanitary sewer overflow. This attachment documents three methods that are most often employed. Other methods are also possible. The person preparing the estimate shall use the method most appropriate to the SSO in question using his/her judgment. Every effort shall be made to make the best possible estimate of the volume.
Method 1 Eyeball Estimate
The volume of very small SSOs can be estimated using an “eyeball estimate.” To use this method, imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the SSO is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to 100 gallons.
Method 2 MeasuredVolume
The volume of some small SSOs can be estimated using this method if it is not raining.
In addition, the shape, dimensions, and depth of the spilled sewage are needed. The shape and dimensions are used to calculate the area of the spill and the depth is used to calculate the volume.
Step 1 Sketch the shape of the contained sewage
Step 2 Measure or pace off the dimensions
Step 3 Measure the depth in several locations
Step 4 Convert the dimensions, including depth to feet.
Step 5 Calculate the area using the following formulas:
Rectangle Area = length x width
Circle Area = diameter x diameter x
0.785 Triangle Area = base x height x 0.5
Step 6 Multiply the area times the depth
Step 7 Multiply the volume by 7.5 to convert it to gallons Method 3 Duration and FlowRate
Calculating the volume of SSOs where it is difficult or impossible to measure the area and depth requires a different approach. In this method, separate estimates are made of the duration
of the SSO and the flow rate. The methods of estimating duration and flow rate are:
Duration: The duration is the elapsed time from the start time to the end time, when the SSO stopped.
Start time is sometimes difficult to establish. Here are two approaches:
• For very large overflows, changes in flow on a downstream flow meter can be used to establish the start time. Typically, the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data.
Conditions at the SSO site change with time. Initially, there will be limited deposits of grease and toilet paper. After a few days to a week, the grease forms a light- c o l o r e d residue. After a few weeks to a month the grease turns dark.
In both cases the quantity of toilet paper and other materials of sewage origin increase in amount. These changes with time can be used to estimate the start time in the absence of other information.
• Sometimes it is simply not possible to estimate the start time.
End time is usually much easier to establish. Field crews on-site observe the “blow down” that occurs when the blockage has been removed. The “blow down” can also be observed in downstream flow meters.
Flow Rate: The flow rate is the average flow left in the sewer system during the time the SSO stopped. There are three ways to estimate the flow rate:
• San Diego Manhole Flow Rate Reference Sheet: This sheet, presented in Figure G1, showsthe sewage flowing from a manhole cover for a variety of flow rates.
The observations of the field crew are used to select the approximate flow rate from the chart.
• Flow meter: Changes in flows in the downstream flow meters can be used to estimate the flow rate during the spill (better for large SSOs). • Estimate based on up-stream connections: Once the location of the SSO is known, the number of upstream connections can be determined from system maps.
Multiply the number of connections by 200 to 250 gallons per day per connection, 8 to 10 gallons per hour per connection, or other flow rates that are consistent with the City’s data for its connections.
Once duration and flow rate have been estimated, the volume of the SSO is the product of the duration in hours or days timesthe flow rate in gallons per hour or gallons per day.

Chapter 3
Wastewater Generation Analysis
This chapter describes the methodologies used to develop existing unit generation rates for wastewater flows from the City of La Mesa. Wastewater flows are then compared and calibrated to existing metered flows, to develop uniform generation rates used to establish existing flows by basin and project future wastewater flows. Future wastewater flows are then compared to the City’s contracted capacity in the Metro system. This chapter presents future wastewater generation projections that can be used by the City to establish a basis for future Metro capacity needs.
3.1 Background
As described in Chapter 2, wastewater generated within the City of La Mesa is collected by Cityowned facilities which connect to Metro conveyance and treatment facilities for treatment and disposal. The City currently has capacity rights in the Metro system of 6.634 mgd.
The City has Metro flow meters at seven (7) locations, and has a number of small interagency connections as shown on Figure 3-1. Based on meter records and information provided by Metro Technical Advisory Committee (Metro TAC) and the City, existing flows from each of the sewer basins was determined as shown in Table 3-1. A summary of all interagency connections is provided in Appendix A.

3.2 Wastewater Generation Rates
The existing City flows were compared with land use data and population projections to develop unit wastewater generation rates within each sewer basin. Unit generation rates were estimated independently using two sources: 1) the City’s current land use data; and 2) population
Chapter 3
Wastewater Generation Analysis
3-2 City of La Mesa
Wastewater Collection System Master Plan

projections compiled by SANDAG (Series 7), for comparison purposes in developing the unit generation rates.
3.2.1 Generation Rates Using City Land Use Data
As shown in Figure 2-1, the City’s existing land uses include single-family residential, multifamily residential, industrial, commercial and institutional. When the GIS land use coverage is overlaid with the City’s parcel database, it was possible to determine the number of single-family and multi-family dwelling units (DU) and acres of industrial, commercial and institutional acreage for each basin. The number of dwelling units and land use acreages, by parcel and basin, are included in Appendix B. Unit wastewater generation rates were “calibrated” to less than 10% of existing flows through an iterative process using typical local-agency standards as guides.
Typically, design standards for agencies in San Diego County assume wastewater flows between 200-400 gpd/du for single-family residential, with multi-family residential ranging from 60% to 75% of single-family residential, and 500-1500 gpd/acre for nonresidential land uses.
Table 3-2 summarizes the calibration of sewer flows for each basin with estimated unit wastewater generation rates summarized by land use. All basins were estimated to have a nonresidential (commercial, institutional, and industrial) unit wastewater generation rate of 500 gpd/ac. Wastewater flows for park land use were not included as these flows are assumed negligible. All basins, with the exception of the University Basin, were estimated to have a calibrated single-family residential and multi-family residential unit generation rate of 270 gpd/du and 180 gpd/du respectively. The University Basin had a calibrated single-family and multifamily residential unit generation rate of 195 gpd/du and 130 gpd/du respectively. All of these unit generation rates are within typical planning and design standards of local county agencies.
Although the University Basin’s residential unit generation rates are slightly lower, they appear reasonable based upon the sewer basin characteristics. The University Basin is an older area of the City, both demographically and by sewer infrastructure age. For that reason, there are generally fewer people per household and a population that is likely more conscious of water usage. The calibrated unit generation rates for the University Basin will be utilized for the existing system capacity analysis. The higher calibrated unit generation rates will be used for all future development including development within the University Basin.
The 2000 census projected 2.78 persons per single family dwelling unit and 2.22 persons per household for multi-family units. Assuming three (3) people per single-family dwelling unit and two (2) people per multi-family dwelling unit, the residential flow per capita ranges from 65 to 90 gallons per day per capita (GPDC). Typically, planning and design standards for sewer agencies in San Diego County typically assume wastewater flows between 65 and 100 gpdc for residential land uses. The aforementioned per capita unit generation rates will be used for comparison with the unit generation rates utilizing existing SANDAG population projections.

3.2.2 Generation Rates Using SANDAG Population
SANDAG provided 2007 residential and employment population projections by basin for the City. These projections were extrapolated from SANDAG (Series 7) data. Through an iterative process, per capita generation rates for residential and employment populations were estimated. Table 3-3 summarizes the estimated unit generation rates by population through the flow calibration process. Per capita unit generation rates were calibrated to less than ten (10) percent of existing flows.

Wastewater Generation Analysis
3-7 City of La Mesa
Wastewater Collection System Master Plan
October 2008
Typically, design standards for agencies in San Diego County assume per capita wastewater generation rates between 65-100 gpdc for residential and 15-35 gpdc for employment populations. Table 3-3 summarizes the calibration for each sewer basin. All basins had an estimated employment per capita unit generation rate of 15 gpdc. All basins, with the exception of the University and Lemon Grove Basins, had an estimated residential per capita unit generation rate of 90 gpdc. This per capita unit generation rate is equivalent to the one estimated from the land use calibration. The University and Lemon Grove Basins had calibrated residential per capita unit generation rates of 60 and 75 gpdc, respectively. The Lemon Grove Basin’s per capita unit generation rate is slightly lower than the other basins’ rate. The University Basin rates, similar to the land use calibration methodology, were also slightly lower than typical standards for County agencies. As discussed above, we believe these rates are reasonable and will be used in the hydraulic model analysis of the existing conditions.
A comparison of the estimated flows for the Land Use and SANDAG-based flow generation methodologies shows a reasonable calibration. Typical standards for calibration to average-day sewer flows range from 5 to 15 percent. The City’s sewer generation rates for each basin were calibrated to less than 10 percent.
3.2.3 Recommended Unit Generation Rates
For future development within the City, it is important to develop uniform unit generation rates.
The City has relatively uniform wastewater generation for land use and population projections based on our unit generation rate analyses. Therefore, for the existing system analysis, the calibrated unit generation rates shown above will be used and for future wastewater generation, the more uniform and conservative generation rates will be used. The sewer generation rates to estimate future flows are summarized in Table 3-4. To determine Equivalent Dwelling Units (EDUs) for non-single family residential land uses, simply calculate the estimated flow based on the recommended unit generation rate for single-family residential land use. The City of San Diego and the County of San Diego utilize 280 and 240 gpd/EDUs respectively.

3.4 Wastewater Flow Projections
By applying the recommended unit generation rates to the projected increase in population, wastewater flow projections were determined at ten (10) year increments through 2030. These projections form the basis for sewer input flows to the hydraulic model, and analyses of future capacity needs in the wastewater collection system.
In order to determine more accurately the magnitude, location and timing of future sewer flows, specific land development information was researched with the City Planning Department. The City provided a current list of approved developments that ranged in size from a few dwelling units up to several hundred units. In addition, the City maintains a list of various development proposals that was used to estimate development beyond the next 3-4 years.
The City’s vacant land for future development is less than five (5) percent and, accordingly, most planned development projects are re-development in nature. The City has several specific planning areas of re-development including Alvarado Creek and Fletcher Parkway. These redevelopment areas are likely the City’s greatest potential for significant residential growth. In addition, the Grossmont Shopping Center may re-develop with a housing element and the Grossmont Hospital site may undergo additional expansion. These have been assumed in this study.
Based on coordination and input from the Planning Department, future development including approved, proposed, and re-development projects were applied to the parcel database to develop build-out flow projections. Our approach used land use and dwelling unit estimates to generate future flow estimates. Figure 3-3 represents the City’s current development planning.
Table 3-6 summarizes the City’s estimated future flows based on our assumed development absorption through 2030.

Wastewater Collection System Master Plan
October 2008
The City may choose to give flow credits for properties when demolition and redevelopment occurs. The City shall estimate the average flow rate of the existing property utilizing the recommended unit generation rates or existing flow meter data.
Using the methodologies outlined above, projected wastewater flow rates generated under City build-out conditions (year 2030) are 6.61 mgd based upon the current City planning and 5.82 mgd based solely upon SANDAG population projections. Figure 3-4 graphically presents the projected wastewater flows through 2030. Both estimates are conservative in that the University Basin under ultimate flows was assumed at the higher unit generation rates (40 percent higher) than its existing generation.

3.5 Metro Capacity
The City currently has capacity rights in the Metro system (comprised of conveyance, treatment, and disposal facilities) equal to 6.634 mgd. Metro is in the process of completing a re-rating study, which will re-allocate capacity to all the participating agencies driven by the new South Bay Reclamation Plant and increased Metro system treatment capacity. This effort has been ongoing for the past three (3) years and can not be officially allocated until the City of San Diego has completed financial audits. Our latest estimate is by late 2008 participating agencies will have received formal notice of their increase in Metro capacity. The preliminary re-rating studies to date have allocated an additional 0.65 mgd of sewer capacity to the City resulting in a total capacity of 6.993 mgd in the Metro System.
The City estimated their average 2006 and 2007 flows at 5.148 mgd, and is currently being billed on 5.148 mgd for Fiscal Year 2008 by San Diego Metro. Based on the current billing flow, La Mesa has an estimated 1.486 mgd of available capacity in the Metro system.
Figure 3-4 shows Metro capacity thresholds based on the future flow estimates given in Table 3-6. Based on current projections, the City’s existing Metro capacity rights will be reached by year 2030, assuming the more conservative population forecast. Additional capacity due to the expected re-rating would indicate that the City will have available capacity to serve planned development at build-out based on both the population and land use forecasts.
3.6 Conclusions
Existing average wastewater flows generated within the City of La Mesa are approximately 5.27 mgd. Currently, the City is being billed by the City of San Diego for 5.148 mgd for Fiscal Year 2008. Based on land use and City planning information, the estimated average flow rate at build-out of the City per the current General Plan is 6.61 mgd. Based on SANDAG population projections, the average flow rate at build-out is estimated as 5.82 mgd.
The City’s current capacity right in the Metro system is 6.634 mgd. Based on the City’s current General Plan projections, the average flow is expected to reach the current capacity around 2030. However, based on the Metro re-rating the City will receive an increase to approximately
6.993 mgd of Metro capacity. Therefore, it is our opinion that with the re-rating the City does not need to acquire any additional sewer capacity. Moreover, because our projections are relatively close to the Metro capacity values, it is unlikely that the City would be in any short-term position to sell excess sewer capacity to another participating agency. The City would be prudent to maintain its current ownership of Metro capacity as other re-development projects may be proposed that would require additional sewer capacity.

City’s Strategic Goals:
Invest in infrastructure to serve the needs of the community.
BACKGROUND:
The City has transitioned from paper maps to electronic Geographic Information System (GIS) mapping to enhance record-keeping and access. The GIS system combines graphical and database information, delivering fast and efficient service to both external and internal customers.
The City does not have in-house resources or staff with adequate expertise to perform this work efficiently, so most of it is outsourced to specialized consultants. By outsourcing, the City has been able to retain expert support in a rapidly evolving industry on an as-needed basis, while maintaining fiscal responsibility.
The City has benefited significantly from the use of this GIS data, which has provided infrastructure records for both capital and private development projects. Maintenance activities have been streamlined through integration with Cartegraph, a software tool for infrastructure asset maintenance. This data is also used for capital improvement and maintenance budgeting as well as performance measurements.
In August 2024, a Master Agreement was executed with Compass Rose GIS to provide GIS and Mapping Services. The terms of the Master Agreement allow for the issuance of task orders in accordance with the City’s Purchasing Policy. The Purchasing Policy requires the City Council to approve contracts exceeding $50,000.
DISCUSSION:
With advancing technology and the dynamic nature of the City’s infrastructure, there is a need to constantly update and upgrade the City’s infrastructure maps. In the coming fiscal year, the City, using Compass Rose GIS services, will be performing the following:
As-needed infrastructure map updates
Continuing digitization of parks and buildings
Digitization of traffic signal inventories and implementation of maintenance tracking on Cartegraph
Assistance with the implementation of See-Click-Fix software Integration of GIS mapping with the Laserfiche system Preparation of special study and presentation maps
Operation, maintenance, and asset management software (Cartegraph) updates Administration of on-line GIS maps and cloud server
Maintenance and administration of GraniteNet Software (CCTV software for videoing the sewer infrastructure) with GIS maps

IMPROVEMENT PROJECT NO. 8323)
ISSUING DEPARTMENT: PUBLIC WORKS
SUMMARY:
Issues:
Should the City Council approve the attached Resolution authorizing the issuance of a task order to BWE, Inc., to provide stormwater drainage design services for the Nancy Drive Street Drainage Improvements project in the amount of $75,545? Recommendation:
Approve the attached resolution authorizing the issuance of a task order to BWE, Inc., to provide stormwater drainage design services for the Nancy Drive Street Drainage Improvements project in the amount of $75,545.
Fiscal Impact:
This task order is funded under Capital Improvement Project No. 8323, Sidewalk Construction, which aims to address sidewalk gaps throughout the city and utilizes Community Development Block Grant funding for eligible areas. Due to the drainage impacts and ponding on the adjacent sidewalks, primarily at the driveway aprons, curb and gutter replacement are being replaced as part of the sidewalk construction.
City’s Strategic Goals:
Invest in infrastructure to serve the needs of the community.
Report to Mayor and Councilmembers
Date: July 22, 2025
Page: 2 of 2
BACKGROUND:
The City received concerns of ponding along the street gutter line on Nancy Drive between Gregory Street and Earl Street. Staff investigated the concerns and concluded that replacing the curb and gutter and repairing driveway apron grades would remedy the situation and protect the street pavement from further deterioration.
In May 2024, the City issued a request for qualifications (RFQ 25-01) and conducted a formal selection process to select highly qualified firms capable of providing various professional services. BWE, Inc. was chosen to provide stormwater drainage design services, and in August 2024, a master agreement was executed. The terms of the master agreement allow for the issuance of task orders to authorize specific items of work on an as-needed basis to the selected consultants.
DISCUSSION:
The Nancy Drive Street Drainage Improvements project design will provide the City with construction improvement drawings to properly lay out the replacement of curb and gutter, as well as the replacement of driveway aprons along the street segment. After the design is completed, the City shall program the project for future construction in the Capital Improvement Program.
CONCLUSION:
Staff recommends that the City Council adopt the attached resolution authorizing the issuance of a task order to BWE, Inc., to provide stormwater drainage design services for the Nancy Drive Street Drainage Improvements project in the amount of $75,545.

The task order for Capital Improvement Project No. 8502, La Mesita Park Drainage Improvements, in the amount of $81,534, is funded by the local Highway Users Tax Account (HUTA) 26 and RTIP LAM44 Roadway Drainage Improvements 26.
Report to Mayor and Councilmembers
Date: July 22, 2025
Page: 2 of 3
City’s Strategic Goals:
Invest in infrastructure to serve the needs of the community. Maintain a community where residents and visitors feel safe.
BACKGROUND:
An existing 60-inch storm drain line runs through La Mesita Park between Dallas Street and a manhole located within Caltrans right-of-way adjacent to the park. The line was originally built in the mid-1900s and conveyed large flows from the areas north of Dallas Street as well as runoff from the park itself. In the early 2000s, off-site flows were diverted to a newly constructed 84-inch reinforced concrete pipe (RCP), which was built within the Caltrans right-of-way.
A preliminary drainage and feasibility study was performed by Ardurra Group, Inc. to assess the existing condition of the pipe, assess the preliminary hydrology and hydraulics of the site and storm drain, and provide remediation alternatives.
In May 2024, the City issued a request for qualifications (RFQ 25-01) and conducted a formal selection process to select highly qualified firms capable of providing various professional services. Ardurra Group Inc. was selected to provide construction management and inspection services, and in August 2024, a master agreement was executed. The terms of the master agreement allow for the issuance of task orders to authorize specific items of work on an as-needed basis to the selected consultants.
DISCUSSION:
The existing 60-inch storm drain is in poor condition and is much larger than is needed to convey drainage from La Mesita Park since off-site flows are now diverted. City staff recommends constructing a new smaller storm drain adjacent to the existing main line and abandoning the existing 60-inch storm drain.
The scope of the work proposed is to develop a construction-ready plan set and specification package, and engineer’s estimate to construct a new 24-inch storm drain line and abandon the existing 60-inch storm drain. Having the same consultant that prepared the preliminary drainage and feasibility study prepare the construction-ready design plans, Ardurra Group, Inc., is cost effective.

SUBJECT: PROPOSAL FOR DESIGN ENGINEERING SERVICES FOR LA MESITA PARK
DRAINAGE IMPROVEMENTS
Dear Ms. Cubberly:
Pursuant to your request, Ardurra Group, Inc. (Ardurra) is submitting our proposal to provide professional engineering, geotechnical, and survey services for the La Mesita Park improvement project. We appreciate the opportunity to continue supporting the City of La Mesa (City). Ardurra’s project understanding, proposed team, and estimated fee are presented herein for your consideration.
PROJECT UNDERSTANDING
Ardurra understands the City is seeking a consulting firm to provide final engineering design services for the replacement of the existing 60” CMP pipe that traverses La Mesita Park as shown in Figure 1. Ardurra prepared a drainage memo for La Mesita Park identifying four alternatives to mitigate the damaged existing 60” CMP pipe. The selected alternative consisted of introducing a new smaller mainline adjacent to the existing mainline, connecting the existing laterals to this new mainline, and abandoning the existing 60” CMP.
For the final design, Ardurra will prepare a final drainage study in accordance with the County of San Diego Hydrology Manual to size the new mainline. The existing pipe would need to be backfilled with material to assure the pipe does not collapse, creating voids and possibly creating soil failures on the surface. Ardurra’s scope of work and deliverables are further detailed below.

SCOPE OF WORK
Task 1. Project Management, Coordination, Meetings, and QA/QC The Project Management task is directed as resource management of the Project Team. Activities include scheduling and monitoring the project team, cost control, and implementing our quality management program (QMP).
Ardurra will coordinate with the City, as necessary, to complete the project tasks. The project schedule, work plan of deliverables, and roles and responsibilities will be defined and mutually agreed upon at the start of the project. Ardurra assumes that there will be no more than four (4) meetings during design; with the initial meeting being a field visit to assess the current existing conditions, and subsequent meetings to be held virtually using the video platform preferred by the City.
Deliverable: Project Management time, Meeting attendance (in person and virtual), Invoicing (PDF) Task 2. Assessment of Existing Conditions
2A. Topographic Survey
Ardurra has secured Aguirre Surveying to perform a survey of the existing park inlets and the invert elevations of the existing manholes within the project area. The survey information will be transposed onto the existing survey from the City’s GIS website. The City’s GIS website has existing 2ft contours that will be utilized for design. Ardurra will use the existing contours to create an existing surface for use in the final drainage study as well as for design of the proposed drainage system. It is anticipated that there are no utilities crossing the main line that will require locating or potholing.

3A. Drainage Study
Using the topographic survey and available GIS data, Ardurra will update the preliminary drainage memo for the purpose of verifying the size of the replacement mainline storm drain pipe. The drainage study will be performed in accordance with the San Diego County Hydrology and Hydraulics Manuals. Using the results from the hydrology analysis, a hydraulic analysis will be performed to verify capacity of the mainline.
Additionally, the drainage analysis will be limited to La Mesita Park and will not include tributary areas outside of the area, including Caltrans.
Deliverable: Updated Drainage Memo (PDF)
3B. Preliminary Improvement Plans
Ardurra will prepare a preliminary plan of the proposed storm drain improvements. The preliminary improvement plan will show the proposed storm drain mainline and the lateral connections from the existing inlets. The proposed laterals will intercept the existing laterals and connect to the new mainline. It will be assumed that the laterals will not require resizing or that inlets will require relocation; however, in the event areas are identified as being deficient, Ardurra will coordinate with the City to add new inlets and laterals. It is anticipated that the preliminary improvements will be shown on a single plan to coordinate with the City for review and approval.

Subject: Proposal for Geotechnical Investigation
La Mesita Park Drainage Improvements Project
8855 Dallas Street La Mesa, California 91942
Dear Mr. Hernandez:
NOVA Services, Inc. (NOVA) is pleased to submit this proposal to perform a geotechnical investigation for the subject project. Based on discussions with you and review of the provided technical memo, we understand the project may consist of replacement of an existing 60-inch storm drain main line at La Mesita Park located at 8855 Dallas Street in La Mesa, California. Based on our experience in the area and review of historic mapping, we anticipate the site will be underlain by fill soils associated with the infilling of an historic drainage. Beneath the fill the site is underlain by alluvium and/or Stadium Conglomerate (Tst). Based on the 1997 Foundation Report prepared by Law/Crandall for the Dallas Street Overcrossing project, perched groundwater is anticipated to be encountered at depths of about 25 feet below the existing ground surface (bgs).
SCOPE OF WORK
The purpose of our services will be to address the geotechnical issues of the proposed development.
Specifically, our scope of work will consist of the following:
• Reviewing geologic maps, prior geotechnical reports, and other readily available literature pertinent to the geotechnical conditions at the site.
• Coordinating with City of La Mesa personnel and Ardurra for site access. • Performing site reconnaissance and marking the proposed boring locations. Underground Service Alert will be notified for underground utility mark-out services. • Hiring a private utility locator to mark potential subsurface conflicts at investigation locations. • Drilling two hollow-stem auger borings to depths up to 15 feet below the ground surface (bgs), or refusal if shallower, using a track-mounted, limited-access drill rig. A NOVA geologist will log the borings and obtain samples for examination and laboratory testing. Figure 1 presents the proposed boring locations.
Attachment B Page 242 of 274
Proposal for Geotechnical Investigation
La Mesita Park Drainage Improvements Project
San Diego, California
May 22, 2025
2 Figure 1. Proposed Boring Locations
• Logging the borings, noting physical descriptions of the soils encountered; soil classifications in accordance with the Unified Soil Classification System (USCS); water table/groundwater if encountered; and obtaining samples for examination and laboratory testing. • Backfilling the borings in accordance with San Diego County Department of Environmental Health requirements.
• Performing laboratory tests on selected soil samples to evaluate material classifications in accordance with the USCS and other pertinent engineering properties including in-situ unit weight and moisture content, grain-size distribution, Atterberg limits, and corrosivity (pH, resistivity, chlorites, and sulfates).
We will prepare a geotechnical report that includes a subsurface investigation map, boring logs, and laboratory test results. We will submit an electronic copy of the report. The report will provide applicable conclusions and recommendations regarding:
• Subsurface conditions beneath the site, including groundwater levels, if encountered, dewatering specifications, and seasonal variations of the water table.

3 • Potential geologic hazards.
• Excavation characteristics.
• Temporary shoring.
• Pipeline support.
• Backfill material and compaction.
• Suitability of existing soils for use as backfill.
• Soil corrosivity.
Please note that it is anticipated that the project site and subsurface materials are free of environmental contamination or pollution. The scope and fee presented herein do not include assessment, sampling, analysis, or management of suspected contaminated materials. However, unexpected conditions can always arise. Should we encounter soil or groundwater that is suspected to be contaminated, either because of odors, colors, free liquids, or other suspicious conditions, we will immediately notify the client. The client should take necessary initial measures to protect workers, the site, and other personnel.
LIMITATIONS AND EXCLUSIONS
Site Access
NOVA’s proposal is based on the understanding that site access will be available during standard workday hours.
Utilities
NOVA will make reasonable efforts to locate surface and subsurface utilities in order to prevent accidental damage to utilities during subsurface exploration activities. NOVA will contact USA to obtain utility locations within the boundaries of the investigation area. A private utility locating contractor will also be notified. NOVA will not be responsible for costs related to damage to any underground utility lines or structures.
Excavated Soils
NOVA will backfill the proposed subsurface explorations in accordance with appropriate regulatory requirements. This proposal assumes that soil cuttings generated during the subsurface exploration will not be affected by hazardous or regulated substances; that there will be no need to conduct special testing to containerize the soils for disposal at a regulated facility, i.e., soils may be disposed of without concern for the presence of regulated chemical constituents. Any such requirements for special soil characterization and disposal will be billed on a time and expense basis.
Stormwater
Please note that stormwater infiltration testing is not within the scope of this proposal. If required, a proposal for ‘design-phase infiltration testing’ can be provided at a later date.

4 Off-Site Disposal of Hazardous Materials
Client acknowledges that NOVA is not and shall not be required to be in any way a ‘generator’, ‘arranger’, ‘operator’, or ‘transporter’ of hazardous materials present at or near the project site, as these terms are defined in applicable Federal or State Statutes. In addition, Client shall sign all manifests for the disposal of substances affected by regulated contaminants.
However, if the parties mutually agree that NOVA sign such manifests and/or to hire for Client a contractor to transport, treat, or dispose of the hazardous materials, NOVA shall do so only as Client’s agent. Client agrees to defend, indemnify, and hold harmless NOVA, its officers, directors, employees and agents from any claim, suit, arbitration, or administrative proceeding, damages, penalties or liability that arise from the executing of such manifests on Client’s behalf.
Further, NOVA will, at Client’s request, help Client identify appropriate alternatives for off-site treatment, storage, or disposal of such substances, but NOVA shall not make any independent determination about the selection of a treatment, storage, or disposal facility.
SCHEDULE
We will begin our investigation as soon as notice to proceed is received. We will mark the investigation locations and notify USA. USA requires 48-hour notice before drilling can start. We will also hire a private utility locator. We anticipate that the fieldwork can be completed within two weeks of the notice to proceed. Laboratory testing and the final report can be completed within five weeks of completing the fieldwork.
FEE ESTIMATE
We will provide the outlined geotechnical investigation scope of work for a lump sum fee of $18,000.
Design development tasks are services that NOVA provides after the geotechnical report has been completed, such as responding to City review comments, design team meetings, answering questions from the design team, and reviewing plans and specifications. For this project, design development services are estimated to be about $2,000 and will be billed as work progresses. Table 1 below presents a breakdown of the fee. The fee is based on our attached 2025 Schedule of Fees and the understanding that this project is subject to prevailing wage law.
The cost of our services may exceed this estimate if unanticipated conditions are encountered that would warrant additional investigation or analysis, or if the proposed plans are changed from our previously stated understanding of the project.

15. HAZARDOUS MATERIALS. It is acknowledged by both parties that the Company’s scope of services does not include any services related to asbestos or hazardous or toxic materials unless specifically identified in our scope of services. In the event the Company or any other party encounters asbestos or hazardous materials at the jobsite, or should it become known in any adjacent areas that may affect the performance of the Company’s services, the Company may, without liability for consequential or any other damages, suspend performance of services on the project until the Client retains appropriate specialist consultants or contractors to identify, abate and/or remove the asbestos, hazardous or toxic materials and warrant that the jobsite is in full compliance with applicable laws and regulations.
16. SAMPLE DISPOSAL. Unless other arrangements are made, the Company will dispose of all samples remaining at the time of report completion. Further storage or transfer of samples can be arranged at Client’s prior written request, subject to a reasonable charge by the Company. In addition, Client acknowledges that contaminated drill cuttings, sample spoils, wash water, and other materials may

be produced as a result of encountering hazardous materials at the site. In such event, the Company shall properly contain, label, and store such materials on-site, and Client shall be responsible for its proper transportation and disposal.
17. AQUIFER CONTAMINATION. Client acknowledges that it is impossible for the Company to know the exact composition of a site’s subsurface, even after conducting a comprehensive exploratory program. As a result, there is a risk that drilling and sampling may result in contamination of certain subsurface areas. Although the Company will take reasonable precautions to avoid such an occurrence, Client waives any claim against, and (without limiting the generality of Section 14 hereof) agrees to indemnify and hold harmless the Company from any claim or liability for injury or loss which may arise as a result of subsurface contamination caused by drilling, sampling, or monitoring well installation. Client also agrees to adequately compensate the Company for any time spent and expenses incurred in defense of any such claim.

FINAL DETERMINATION OF SEWER SERVICE
CHARGES FOR FISCAL YEAR 2026 TO BE
COLLECTED ON THE COUNTY PROPERTY TAX ROLL
AND DIRECTING THE CITY CLERK TO FORWARD A
COPY OF THE RESOLUTION AND THE REPORT TO
THE OFFICE OF THE SAN DIEGO COUNTY AUDITOR
ISSUING DEPARTMENT: Public Works
SUMMARY:
Issues:
Should the City Council adopt the attached resolution approving the sewer charge amount for each parcel as described in the Fiscal Year (FY) 2026 sewer charge report and authorize the City Clerk to submit the sewer charge for each parcel to the County Auditor for collection on the FY 2026 property tax bills? Recommendation:
That the City Council adopt the attached resolution approving the sewer charge amount for each parcel as described in the FY 2026 sewer charge report and authorize the City Clerk to submit the sewer charge for each parcel to the County Auditor for collection on the FY 2026 property tax bills.
Fiscal Impact:
Through an agreement with the County of San Diego, the City pays a fee of $0.10 per parcel for the collection of sewer service charges on the tax bill. Sewer charges will be levied on an estimated 13,205 parcels in FY 2026, at a total estimated cost of $1,320.50. This amount is deducted by the County from the City’s apportionment of property tax payments.
Report to Mayor and Councilmembers
Date: July 22, 2025
Page: 2 of 4
The City will collect approximately $13,397,925.18 in sewer revenue from property tax payments in FY 2026. This revenue is received from the County in monthly apportionments, with a majority of the revenue collected in January and May after property tax bills are due. Additionally, the City's Finance Department will directly bill and collect an estimated $1,178,105.28 in sewer service charges from an estimated 219 properties that cannot be placed on the tax roll due to various circumstances. Sewer service revenue is deposited into the Wastewater Fund and is used to fund the City’s sewer program, including operation and maintenance, sewer treatment and conveyance, infrastructure improvements, and debt service.
City’s Strategic Goals:
Ensure a strong financial outlook through careful planning, sustainable service levels, and fiscal sustainability.
Invest in infrastructure to serve the needs of the community.
BACKGROUND:
On June 26, 2012, the City Council adopted Ordinance No. 2012-2823 authorizing the collection of La Mesa sewer service charges on the County property tax roll as a fixed charge special assessment.
The City has an agreement with the County of San Diego for the collection of taxes and special assessments. As part of the agreement, the County collects the fixed charge special assessments levied by the City at the same time and in the same manner as County property taxes are collected. A special assessment is defined as a levy placed upon real property (land or land and improvements) for the purpose of paying for a special service, the amount of which is based on the benefit received from the service provided.
Sewer service charges are collected from all users of the City’s sanitary sewer system pursuant to La Mesa Municipal Code Section 17.12 and the laws of the State of California.
The City levies the sewer service fee under the authority of California Health and Safety Code Section 5471. Sewer charges are subject to the limitations prescribed in Article XIIID (Proposition 218) of the California Constitution. On July 22, 2025, the City Council approved a rate increase of 5.96% for the average single-family home customer in FY 2026.
DISCUSSION:
As part of the annual sewer billing process, the City will be mailing the week of July 23 a courtesy notification letter to the record owner of each parcel connected to the City’s sanitary sewer system, with the estimated sewer charge amount to be collected on the
Report to Mayor and Councilmembers
Date: July 22, 2025
Page: 3 of 4
FY 2026 property tax bill. The letter provides property-specific information to assist property owners with planning and budgeting for property tax payments, rental properties and impound accounts. The courtesy letters also provide information for the property owner to request a sewer billing adjustment before the charges are placed on the property tax bill. Municipal Code Section 17.12.040 authorizes the City Manager to establish policies and grant exceptions from the established sewer service charges in certain situations. The sewer charge adjustment policy and the request form are available on the City’s website. Adjustment requests may be submitted at any time throughout the year; however, the County charges a $15 per parcel correction fee for processing billing changes after the August 10th submittal deadline.
To align with the goals of the Climate Action Plan, residents have the option of opting out of the paper annual courtesy notification. Residents will still be able to obtain their water usage information online from the City’s website. A resident who opts out of the annual notification will continue to receive public hearing notices for sewer fees, pursuant to Article XIIID (Proposition 218) of the California Constitution.
Property owners also can review their annual sewer charges online on the City’s website at http://www.cityoflamesa.us/sewer . The winter water usage and billing calculations are available online going back to 2012 allowing property owners to track changes in their winter water average and the bill amount from year to year.
In order to collect the sewer charges on the property tax roll, Health and Safety Code Section 5473 requires that a written report containing a description of each parcel receiving sewer service and the amount of the charge for each parcel, be prepared each year and filed with the City Clerk. Sewer charges must be computed in conformity with the adopted schedule of sewer service fees. The FY 2026 sewer charge report, with the amount to be levied against each parcel, was filed with the City Clerk on July 11, 2025.
The City Council is required to hold a public hearing prior to making a final determination of the amount of the sewer service charge to be levied against each parcel for the fiscal year. Pursuant to Section 5473.1, a notice of filing of the FY 2026 sewer charge report and the time and place of the public hearing was published two times in the Daily Transcript on July 8, 2025, and July 15, 2025.
On or before August 10 of each year, the City must certify and deliver the adopted resolution and a copy of the approved report with the levy amounts for each parcel, to the County Auditor to be added to the assessment roll for collection on the property tax bill.
Following the public hearing, staff will prepare the final parcel report, along with any changes requested by residents and approved by City staff, for submittal to the County.
Parcels that cannot be placed on the tax roll, such as government agencies or homeowner associations, are billed separately by the City.
Report to Mayor and Councilmembers
Date: July 22, 2025
Page: 4 of 4
CONCLUSION
Staff recommends that the City Council adopt the resolution approving the sewer charge amount for each parcel as described in the FY 2026 sewer charge report and authorize the City Clerk to submit the sewer charge for each parcel to the County Auditor for collection on the FY 2026 property tax roll.
