21 construction; cleaning requirements; testing of sewer lines and manholes; postinstallation video inspection; soils testing; inspection of structure excavations; and backfill compaction testing. The project-specific Contract Drawings and Special Provisions include additional testing requirements, as applicable.

The City provides inspection by utilizing its own staff or outsourcing to qualified consultant for the inspection of new sewer construction and rehabilitation projects. City requires that “As-Built” sewer plans of the completed projects be submitted prior to final approval for acceptance of sewer facilities for public use. In compliance with City policy, the City also requires that all newly constructed sanitary sewer lines be inspected by experienced City staff or qualified consultant prior to acceptance of the project for City maintenance.

6.0 OVERFLOW EMERGENCY RESPONSE PLAN
The City has developed and implemented a Sanitary Sewer Overflow Emergency Response Plan (SSOERP) that identifies measures to protect public health and the environment, as required by SSSWDR Section D.13.(vi) by including:
1) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
2) A program to ensure an appropriate response to all overflows; 3) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification; 4) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; 5) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and
6) A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be

Sewer System Management Plan (SSMP) May 2025
22 necessary to determine the nature and impact of the discharge.

6.1 Overflow Response Procedure
Goals with respect to responding to SSOs are as follows:
• Notify the Sewer Maintenance District of the Overflow • Minimize the volume and damage from the SSO by responding promptly when notified;
• Contain and prevent the overflow from entering the storm drain system; • Minimize public contact with the spilled wastewater;
• Stop the overflow as soon as possible.
• Completely recover the overflow and return it to the sewer system. • Clean up the area contaminated by the overflow.
• Meet the regulatory reporting requirements;
• Compile information and conduct an investigation to determine the probable cause of the overflow.
• Document the events, including taking photographs, during the overflow and response activities
• Notify the public when a threat to public health exists.

The City is responsible for reporting sanitary sewer overflows on CIQWS within the City.

The Sanitary Sewer Overflow Procedure described in Chapter 6 of the SMMP are utilized by the City. Furthermore, the City 24-hour emergency phone number 1-323-246-0214 is readily available to City staff and residents to use in promptly notifying City Public Works Department staff of SSO events in the City.

The City’s SSOERP complies with the additional notification requirements outlined in SWRCB Order WQ 2008-0002-EXEC, Adopting Amended Monitoring and Reporting Requirements for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, including:
1) For any discharges of sewage that results in a discharge to a drainage channel or a surface water, the Discharger shall, as soon as possible, but not later than two (2) hours after becoming aware of the discharge, notify the State Office of Emergency Services, the local CITY OF Montebello, CITY SEWER SYSTEM MANAGEMENT PLAN health officer or directors of environmental health with jurisdiction over affected water bodies, and the appropriate Regional Water Quality Control Board.
2) As soon as possible, but no later than two (2) hours after becoming aware of a discharge to a drainage channel or a surface water, the Discharger shall submit to

6.1.2 Emergency Response Plan Procedure

Page 566 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
24 Notification, Investigation and Mobilization have been developed by the City as following:

Calls for SSOs can be received by Police Dispatch, Code enforcement or the City Public Works Department. The City has 24-hour call service via Public Works Department dispatch and regular hour dispatch from the Engineering Division and Code Enforcement.

Action following notification of an overflow:
• When a call is received reporting a sewer overflow during normal business hours (Monday thru Thursday), the Superintendent is notified who subsequently dispatches field personnel or sewer maintenance contractor to respond and investigate.
• When a call is received after hours, weekends or holidays, Police Dispatch or 24- Hour dispatch will contact the on-call Standby personnel and/or sewer maintenance contractor who will respond and investigate. • If it is determined that the overflow is in the City’s sewer system, then mobilization will begin. If the overflow is the County Sanitation District’s (LACSD) or adjacent City’s sewer system, then they shall be contacted immediately.

The overflow response in the field will be directed by the Sewer Maintenance District or supervisor and/or staff who are trained and experienced in responding to overflows. • A crew will be dispatched to the scene to begin the response actions. i. Staff members will begin containment of spill to prevent overflow from entering the storm drain system.
ii. Sewer maintenance contract staff will be informed to start corrective action immediately, if required.
iii. Staff/Contract operators will begin corrective action to eliminate the cause of the overflow.
iv. Upon containment and corrective action, recovery and clean-up will commence.
v. Notification and reporting.

Containment and recovery should occur as close as practical to the location of the overflow with attention to blocking off any storm water catch basins to prevent sewage from entering the storm drain system. If sewage has entered the storm drain system, containment and recovery will take place downstream of the entry point where it is

Page 567 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
25 accessible and safe to work. Containment will be performed by installing Sandbags, containment berms and covers, absorbent pads or plugs will be deployed to dam up the overflowing sewage to prevent the movement of the sewage from traveling further or prevent entry into the storm drain system. Vacuum trucks will be used to collect the overflow sewage and return it to the sewer system.

Corrective Action will be taken in place upon arriving to the overflow location. Public Access to the immediate area of the overflow is restricted to minimize potential impacts to public health by redirecting pedestrian and automobile traffic away from the overflow through the use of traffic cones, plastic tape, barricades, or local law enforcement.

The extent of the overflow and its potential impacts to the public health are assessed by personnel. This process involves determining if any private property owners/residents may be exposed to raw sewage, making direct contact with private property owners/residents who have been or may be directly affected by the overflow, advising private property owners/residents of the potential health hazards associated with contact with raw sewage, and identifying prudent measures to be taken by private property owners/residents.

Simultaneous efforts include determining the path and final destination of the sewage spill and potential exposure to the public. If wastewater from the overflow is ponding in a location that can be isolated, then personnel will set up barricades to prevent public access. Traffic control is set up to prevent vehicles from entering locations where the overflow has contaminated public or private streets. Personnel are instructed to direct pedestrians and automobile traffic away from the path and final destination of the overflow. Cooperation with local law enforcement and public works officials is a key component to ensure that public exposure to the overflow is minimized and to ensure spill site security.

When possible, personnel will contain and recover the overflow in the immediate vicinity of the overflow before it enters a storm drain or catch basin. Measures to affect such containment include damming the overflow path with sandbags in the street gutter and recovering the impounded water with a vacuum truck or sewer cleaning jet Vactor truck, or using sandbags to divert the overflow back into a nearby sewer manhole.

Personnel can also use plugs in the storm drainpipe or catch basin further downstream to prevent the flow of sewage into the storm drain system. A Vactor truck will be used to collect the wastewater and return to the sanitary sewer system.

The cause of the overflow will be investigated, and the necessary corrective action will

Page 568 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
26 be taken to stop the overflow and/or correct the condition that caused the overflow if the overflow has already stopped.

Corrective actions to stop a sewer overflow include as following:
• Clearing a pipe blockage with a jet Vactor or rodding machine, • Removing debris from a manhole,
• Upstream flow diversion, and
• Bypassing of wastewater around the blockage using vacuum trucks or pumps.

Cleaning up shall be performed after the overflow has been stopped. All locally impounded wastewater is recovered with a vacuum truck and returned to the sanitary sewer system. All visible debris of wastewater origin from the overflow location(s), street(s), curb and gutters, and the overflow runoff path is physically removed. Overflow location(s), street(s), curb and gutters, and the runoff path are flushed with potable water, typically delivered by a vacuum truck or water truck. The flush water is also recovered and returned to the sewer system. All sandbags and other containment equipment are removed to complete the cleanup in the storm drain system.

If spilled wastewater reaches natural watercourses or other areas accessible to the public, input is solicited from the responsible jurisdiction regarding additional measures which may be necessary or appropriate for a complete cleanup. Additional cleanup measures are completed as directed.

Private properties impacted by overflows or backups from problems within the City’s system are cleaned up by a professional restoration company dispatched by the property owner. Claims for property damage are submitted to the City Clerk’s office and handled by the City’s Insurance and Claims Coordinator.

Sewer System Management Plan (SSMP) May 2025
31 6.1.5 Post Clean Up Activities
Once cleanup of an overflow is complete, the incident must be reviewed and any appropriate measures to prevent recurrence must be implemented. Follow-up CCTV inspection is performed when an overflow was caused by a blockage to verify complete removal of the material causing blockage. If the overflow was avoidable by preventative maintenance, then maintenance activities are added or adjusted as necessary. An example is to increase the frequency of line cleaning where heavy grease build-up has caused an overflow to occur, while source control efforts are reviewed. If the overflow was caused by factors generally outside the City’s control, such as vandalism, steps are still taken to minimize recurrence such as strengthening security by locking down manhole covers, increasing area surveillance, and requesting neighborhood assistance in reporting vandalism.

Regardless of the size or type of overflow, all overflows are investigated thoroughly.

Following the investigation, information shall be documented on the SSO Field Incident Report and After Action Report.

6.1.6 Emergency Response and Personnel
The City has the necessary personnel to respond to almost any emergency, including sewer blockage, pipe failure, and vandalism. The urgency and seriousness of any wastewater overflow results in the full commitment and availability of all staff in the Sewerage System Section to respond. Additional City personnel are utilized for specialized assistance as needed. Contractors with emergency response capabilities are also used to assist in emergencies as needed. Each sewer lift station has a specific Emergency Response Plan which is kept at the facilities for personnel.

An emergency contact list is maintained which includes the home phone number of all employees in the Sewerage System Section. All supervisors and managers in the Sewerage System Section are assigned cell phones and are accessible 24-hours a day. A table of organization for the Sewerage System Section is shown on Sections 2.3.1a and

2.3.5 of this SSMP. Emergency Equipment, in addition to the normal compliment of equipment utilized by the Division for maintenance and repair of the sewerage system, specific items are maintained for use during emergency conditions. Such equipment includes:
• High pressure jetting machines to clear pipe blockages. • Portable engine driven electrical generators for use at pumping plants during power outages.

Page 574 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
32 • Vacuum tankers to transport flow around blockages or to remove wastewater from a containment location in a street or storm drain.
• Pre-filled sandbags, flat bed and crane trucks for use in establishing containment dams.
• Front loaders for emergency earth moving operations.
• Portable engine driven centrifugal pumps (trash pumps) to bypass wastewater around pipe blockages and remove wastewater from storm drain channel containment locations.
• Hoses and lightweight quick-coupling piping in various sizes for use in bypass pumping.
• Pipe repair clamps, inflatable sewer plugs, and other miscellaneous pipe repair parts.
• Water trucks for use in cleanup operations.
• Portable lights, air compressors, centrifugal blowers, and other miscellaneous equipment.

6.1.7 Training
Training of Sewage System Section personnel is completed annually (more frequently if needed) with both classroom training and field exercises to simulate a spill. Written exercises are utilized during training to ensure that staff is competent in spill response; volume estimation; notification and reporting; containment and clean-up; and proper completion of required SSO forms.

Lastly, on-the-job training is administered to subordinate staff, by experienced supervisors and lead workers, during and following actual overflow events to further reinforce the annual training and to analyze event specific issues.

6.1.8 Records Retention
All formal reports, photographs, hand calculations of volume estimations, hand-written notes and any other documentation relating to SSOs shall be kept for a period of at least five years. All original documents shall be kept in the office of the Engineering Office,

Page 575 of 1116 ends

Sewer System Management Plan (SSMP) May 2025
33 with copies scanned and saved on the City computer server for archival purposes.

7.0 FOG CONTROL PROGRAM
The City’s Fats, Oils and Grease Control Program addresses the mandatory SSMP provisions outlined in the SSSWDR Section D, 13 (vii). The City’s FOG Control Program helps reduce the amount of fats, oils and grease discharged to the sanitary sewer system, by including:
1) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
2) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
3) The legal authority to prohibit discharges to the system and identify measures to prevent SSO’s and blockages caused by FOG;
4) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; 5) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; 6) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and 7) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified above.

7.1 Public Education Outreach Program
The outreach program for proper disposal of FOG and other SSO prevention measures such as the installation of backwater valves, house lateral maintenance, etc. is disseminated to City residents through publication of Annual Reports, brochures and individual notices to property owners.

City Public Works Department personnel assist in passing useful information on SSO

Page 576 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
34 prevention and FOG on to home and business owners. To complement County efforts, the City will initiate its own Public Education Outreach Program. This will consist of including SSO and FOG related articles from County DPW and other sources in City newsletters and by maintaining continuous communication with the LA County, City residents and other stakeholders on these and other issues.

FOG inspections include an assessment of the grease control device (GCD) condition (if applicable), food and grease waste disposal practices, drain screen presence and condition, spill preparedness, and employee training. During the inspections, business owners are educated on the City’s FOG Control Program and the best management practices (BMPs) required for proper FOG disposal to prevent SSOs. Businesses receive a list of corrective actions following the inspection, and inspectors work with business owners until compliance is achieved. Enforcement actions are taken as necessary.

7.2 Disposal Methods for FOG Generated within the City’s Sanitary Sewer System
The City is committed to reducing the amount of FOG discharged to the sanitary sewer system through the implementation of an effective public outreach program. The City’s Department of Public Works Utility Division identifies all new food service locations within the City’s service area. FOG compliance inspections are annually conducted at selected food service and manufacturing establishments (FSE) as part of the City’s FOG Inspection Program. High priority facilities are routinely selected for inspection. These include FOGproducing facilities that are near known FOG hotspots and sites that failed to comply during the last inspection. Facilities that did not receive an inspection in the past fiscal year are also prioritized for inspection. It should be noted that some FOG inspections are conducted in conjunction with storm water compliance inspections.

A list of vendors which offer collection and disposal services within the City’s service area can be found at the CalFOG website (www.calfog.org). Food service establishments (FSEs) are annually inspected for FOG disposal compliance during FOG inspections.

Grease control devices (GCDs) are required to have a total grease and solids accumulation of less than 25% by volume in order to be in compliance.

7.3 The Legal Authority to Prohibit Discharges to the System and Identify Measures to Prevent SSOs and Blockages Caused by Fog
The legal authority to prohibit discharges of FOG into the sewer system is discussed in Chapter 3 of this document. Requirements for grease interceptors at food establishments to prevent the discharge of grease to the collection sewer system and educating the public on proper disposal methods for FOG are also discussed elsewhere in this chapter.

Page 577 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
35 The City is currently in the process of creating a FOG Management Program. This Program will be written with the adoption of refinement of the Ordinance 8.04.010 similar to the LA County Public Health and Safety Code, Title 11 as currently in effect and as amended through Los Angeles County Ordinance No. 97-0071, and portions of Title 8, Consumer Protection, as contained in Los Angeles County Ordinance No. 97-0071. These ordinances and codes are the health and safety ordinance of the City of Montebello, protecting and preserving the public health, safety and welfare by the enactment, inspection and enforcement of the health regulations therein contained and providing penalties for the violations FOG.

7.4 Requirement to Install Grease Removal Devices, Design Standards for Grease Removal Devices, Maintenance Requirements, BMP Requirements; Record Keeping and Reporting Requirements
The City is responsible to enforce Sanitary Sewers and Industrial Waste Programs in the City.

The Industrial Waste Program of the County is managed by the Environmental Programs Division of County DPW. The design standards for grease removal devices and all the requirements imposed on industrial waste facilities that discharge waste or FOG into the City’s sewer system are similar to those imposed in the Unincorporated County and as presented in portions of Title 8 of LA County Public Health and Safety Code.

DPW does not issue permits or inspect domestic sewage disposal to the sanitary sewer system. However, the LACO Code prohibits the discharge of “any material, which may create a public nuisance, or menace to the public health or safety, or which may pollute underground or surface waters, or which may cause damage to any storm-drain channel or public or private property” as noted in Section 20.36.010. If during inspection by LACPW, the Districts’ personnel determines that a FOG-related problem exists and is traceable to a domestic sewage source of such character that is not satisfactory, under LACO Code 20.20.100, pretreatment could be required or the discharge required to be eliminated. Domestic waste containing FOG can lead to spills, which are public nuisances and violation of California Health and Safety Code Division 5, Part 3, Chapter 6, Article 2, which can also be used to impose appropriate domestic sewage discharge requirements.

FSE’s are required to size, design and construct grease traps and inceptors according to the LACO Plumbing Code. Additionally, they are required to be approved, installed, and operated in a manner to control discharges of FOG into the sanitary sewer system and to ensure that the facilities do not create nuisances, menaces to public peace, health or

Page 578 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
36 safety hazards, or adverse impacts to the public sewage system, soil, underground, and/or surface waters.

The Industrial Waste online page on the County’s website provides standard drawings for grease pretreatment devices:
https://cleanla.lacounty.gov/industrial-waste/#Obtaining-Clearance The IWDP Conditions and Limitations have a minimum maintenance frequency condition and a requirement to maintain the GRD in proper working order. During inspections, inspectors physically examine the GRD. If a grease interceptor (GI) is used, FSEs are required to open and inspect it. If issues are identified, they are documented, and a job order is created. The FSE signs off on the order and receives a receipt. If cleaning records are not provided, or if the GI cannot be accessed, the FSE must clean it.

Permit conditions require:
• GIs to be cleaned at least once every three months
• FSEs with grease traps are required to perform daily maintenance The Pretreatment Guidelines for Restaurants and Food Service Operations provide guidelines and best management practices for selecting and installing pretreatment devices. These guidelines outline the installation requirements for grease interceptors and offer a list of alternative pretreatment devices that can be used in lieu of a grease interceptor.

During inspections, inspectors verify whether best management practices are being followed, such as maintaining proper documentation, using adequate devices, and employing appropriate disposal methods. In incorporated areas, inspectors distribute flyers outlining the dos and don’ts of FOG management and request that these flyers be displayed at workstations for workers to see.

As a condition of the Industrial Waste Permit, FSEs must record the maintenance of grease trap/interceptors on a maintenance log report. The log records date of the service performed, types of services performed, and person/company providing service.

Additionally, for any liquid or solid industrial wastes transported from the site, FSEs must obtain and keep copies of receipts for grease trap/interceptor maintenance and pumping for at least 180 days.

The maintenance log report and receipts shall be made available to the county and the City (if applicable) upon request.

City of Montebello
Sewer System Management Plan (SSMP) May 2025
37 The County implements the following procedure to identify and manage sections of the system impacted by FOG blockages:
• Identification: Sections impacted by FOG blockages are identified through regular inspections conducted by cleaning crews, CCTV inspections, and reports of spills.
• Investigation: Once identified, these sections are thoroughly investigated to assess the extent of the blockages and determine the appropriate actions needed to address them.
• Maintenance: Based on the investigation findings, a periodic cleaning schedule is defined and implemented for each affected section to ensure ongoing maintenance and prevent future blockages.

7.5 Authority to Inspect Grease Producing Facilities, Enforce Authorities, and Evidence of Adequate Staffing To Inspect and Enforce the FOG Ordinance The LACO Code, Section 20.24.090, which will be adopted by the City, gives the City Director of Public Works the authority to inspect FOG-producing facilities, prohibiting the discharge of substances that may obstruct or require frequent maintenance of the sewer system.

When SMD encounters FOG issues in the collection system, whether from spills CCTV inspections, or sewer cleaning, the source of the problem is evaluated as either residential, commercial, or both. For residential spills, SMD may notify residents door-todoor, providing information on proper grease disposal practices. For recurring issues, the affected area is placed on a preventive maintenance schedule.

In the case of commercial spills, the incident is referred to EPD for investigation. EPD checks GRD maintenance and requires corrective actions when needed. If an FSE without a GRD is responsible for a spill, EPD mandates the installation of a GRD. If a GRDequipped FSE causes a spill, more frequent maintenance may be required. All investigations are documented in the HMS database, and results are communicated to SMD as relevant.

The County DPW in concert with the City Engineer is also responsible for the enforcement of all industrial waste permit and Code violations in the City.

7.6 Cleaning Schedule for Identified FOG Prone Sewer Segments Cleaning of FOG prone segments is contracted and performed by the Sewer Management

Common source control BMPs include pre-wiping oily pans and dishes prior to washing them, installing drain screens in sinks to catch food particles, cleaning hoods regularly, training employees, and maintaining records of training and maintenance activities. As previously discussed, the City conducts FOG inspections at food service establishments (FSEs) for compliance with the source control BMP requirements.

8.0 SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
The City’s System Evaluation and Capacity Assurance Plan addresses the mandatory provisions as outlined in the SSSWDR Section D.13.(vii). These include the following:

Page 581 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
39 1) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events.
2) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (1) above to establish appropriate design criteria; and 3) Capacity Enhancement Measures: The steps needed to establish a short- and longterm CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding.
4) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (1)-(3) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14.

8.1 System Evaluation and Capacity Assurance
The City Public Works Department Engineering Division is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized and easily maintainable. Public Works Department also provides a supporting role in reviewing all proposed sewer plans for new developments in the City to ensure that they conform to County design standards and particularly to ensure that LA County Sanitation District’s requirements for acceptability of treatment. A comprehensive capacity evaluation using a dynamic hydraulic model is performed to quantify flows and capacities in all major sewers under current and future flow conditions.

The hydraulic model was used to generate peak flows in each modeled pipe and to evaluate pipe capacities. A pipe was considered to have inadequate capacity if the ratio of flow depth to pipe diameter (d/D) at peak dry weather flow exceeded 75 percent under either existing or future conditions.

Page 582 of 1116 ends

City of Montebello
Sewer System Management Plan (SSMP) May 2025
40 The City signs a yearly Sewer Management Agreement with Los Angeles County. The County uses CCTV inspection as the primary means for collecting visual observations of system conditions. This CCTV inspection program digitally records the condition of the pipe interior from manhole to manhole using a robotic camera tethered to a camera van.

While the video is being captured, a National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP) certified crew member views and logs events such as defects and observations using the standardized NASSCO PACP observation codes. With GraniteNet, the digital video inspections files are transferred via cloud enabling access to anyone with credentials and password access using a laptop or mobile device.

In addition to CCTV inspection, visual inspection is conducted on sewer facilities during sewer system maintenance activities. In the past, a field crew would documents visual observations and system issues on a form to trigger follow up inspections and repair actions. With the implementation of Cityworks, field crews now provide these observations electronically using mobile devices for immediate communication to SMD Superintendents and Supervisors to trigger follow-on actions to address issues.

8.2 Adequate Capacity and Correct Design
In addition to the criteria used to evaluate the capacity of existing sewers (as described in the preceding section), the City has separate criteria they enforce for the design of all new sewers. The City’s Public Works Department Engineering Design Guidelines and Sanitary Sewer Master Plan establish design guidelines for private development and public projects within the City of Montebello. The Sanitary Sewer Master Plan identifies design criteria for new sewer systems including unit flow factors, peaking factors, hydraulic friction factors, minimum slopes, and maximum allowable depth of flow. Prior to the approval of new sewers, the City requires that developers perform a sewer area study that applies these criteria to confirm the adequacy of the proposed sewers.

The City Engineer or hired qualified private company provides thorough review of all sewer plans for proposed development projects in the City to ensure that: 1) they are properly designed with sufficient capacity for current and future base, peak and wet weather flow demands; and 2) any impact of proposed project on existing sewer system is mitigated prior to being approved by the City Engineer. During construction, the projects are continuously inspected by the City Engineer or hired construction inspectors to ensure that the sewer facilities are constructed in accordance with the approved plans and specifications.

Sewer System Management Plan (SSMP) May 2025
41 8.3 Capacity Enhancement Plan
The collection sewer system capacity enhancement program is a combined effort of City Public Works Department Engineering Division. The City programs to optimize the use of available sewer capacity and prevent SSOs include the CCTV program to identify pipe segments needing repairs or with I/I or tree root intrusion problems, sewer cleaning program and the CIP program to effect repairs or replacement of damaged pipes.

The City’s CIP is presented in the 2010 Sanitary Sewer Master Plan as previously described. It includes recommended completion dates for the various phases of replacement and rehabilitation. The Engineering Department reviews the CIP on an annual basis and adjusts if necessary to address the most critical issues.

9.0 MONITORING, MEASUREMENT, MODIFICATION PROGRAM
The City’s Monitoring, Measurement, and Program Modifications addresses the mandatory provisions outlined in SSWDR Section D.13.(ix). These components include:
1) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities;
2) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP;
3) Assess the success of the preventative maintenance program; 4) Update program elements, as appropriate, based on monitoring or performance evaluations; and
5) Identify and illustrate SSO trends, including: frequency, location, and volume.

9.1 Performance Measures
The City will document all relevant data on SSOs that occurred in the City. These will include the quarterly SSO reports from City PWD, Annual Reports published by City, Sewer Maintenance Productivity Report and any special reports to regulatory agencies etc. In addition, LA County publishes a Sewer Maintenance District yearly Productivity Report of all services provided. The data will be analyzed to evaluate the effectiveness of the City’s SSMP.

City of Montebello
Sewer System Management Plan (SSMP) May 2025
42 9.2 SSMP Program Effectiveness Evaluation
The evaluation of the City’s SSMP Program Effectiveness shall be based on such key performance indicators as the total number of overflows, overflow response time, reduction in repeated incidents of SSO at some location, total overflow equal to or greater than 1,000 gallons or reaching the waters of the United States and reduction in number of overflows that are caused by sewer capacity-related problems.

Every three years, the City performs an internal audit of the SSMP and the SSMP program implementation. Each element of the SSMP is reviewed for effectiveness towards reducing the frequency and/or mitigating the impacts of spills and for compliance with the General Order requirements. Corrective actions to address identified deficiencies are prioritized, scheduled and incorporated into plans.

9.3 Preventative Maintenance Program Modification
The City shall continually update or modify the key elements of its SSMP based on the results of the above mentioned monitoring and program effectiveness evaluations. The City shall also make recommendations, as necessary, on elements of the SSMP to be adjusted or revised within the City boundaries to better serve its residents.

The City updates this SSMP every six years. The update consists of reviewing the existing SSMP language and updating any outdated information by incorporating adopted and implemented recommendations from previous SSMP program audits. Upon completion of the six-year SSMP update, the SSMP is provided to the City Council for approval. Upon City Council approval, the SSMP is uploaded to the State Water Board CIWQS database and certified.

9.4 Update Program Elements
The Public Works Director is responsible for ensuring that the wastewater system is managed in accordance with this SSMP. Monitoring and performance standards are annually evaluated by the Public Works Director and any improvements or modifications to the SSMP program elements as noted will be implemented as soon as practical.

9.5 Identify and illustrate SSO trends
Mapping of SSO Frequencies - The monthly numbers of SSOs charts and graphs prepared by City will be presented in Appendix J. The graphs are used for identifying SSO trends and to evaluate overall program effectiveness. The charts are used to identify SSO trends and as an indicator of possible Infiltration/Inflow problem. SSO trends are also annually

STATE OF CALIFORNIA

WATER RESOURCES CONTROL BOARD
ORDER NO. WQ 2013-0058-EXEC

AMENDING MONITORING AND REPORTING PROGRAM
FOR

STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR

SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board) finds:

1. The State Water Board is authorized to prescribe statewide general Waste Discharge Requirements (WDRs) for categories of discharges that involve the same or similar operations and the same or similar types of waste pursuant to Water Code section 13263(i).

2. Water Code section 13193 et seq. requires the Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) to gather Sanitary Sewer Overflow (SSO) information and make this information available to the public, including but not limited to, SSO cause, estimated volume, location, date, time, duration, whether or not the SSO reached or may have reached waters of the state, response and corrective action taken, and an enrollee's contact information for each SSO event. An enrollee is defined as the public entity having legal authority over the operation and maintenance of, or capital improvements to, a sanitary sewer system greater than one mile in length.

3. Water Code section 13271, et seq. requires notification to the California Office of Emergency Services (Cal OES), formerly the California Emergency Management Agency, for certain unauthorized discharges, including SSOs.

4. On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer Systems"1(hereafter SSS WDRs) to comply with Water Code section 13193 and to establish the framework for the statewide SSO Reduction Program.

5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that the Executive Director may modify the terms of the MRP at any time.

6. On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for the SSS WDRs to rectify early notification deficiencies and ensure that first responders are notified in a timely manner of SSOs discharged into waters of the state.

7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES, pursuant to Water Code section 13271(a)(3), forwards the SSO notification information2 to local government agencies and first responders including local public health officials and the applicable Regional Water Board.

and Cal OES is duplicative. To address this, the SSO notification requirements added by the February 20, 2008 MRP revision are being removed in this MRP revision.

8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the California Water and Environment Association (CWEA), the State Water Board committed to redesigning the CIWQS3 Online SSO Database to allow "event" based SSO reporting versus the original "location" based reporting. Revisions to this MRP and accompanying changes to the CIWQS Online SSO Database will implement this change by allowing for multiple SSO appearance points to be associated with each SSO event caused by a single asset failure.

9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements changes to SSO categories by adding a Category 3 SSO type. This change will improve data management to further assist Water Board staff with evaluation of high threat and low threat SSOs by placing them in unique categories (i.e., Category 1 and Category 3, respectively). This change will also assist enrollees in identifying SSOs that require Cal OES notification.

10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program4 objectives, assess compliance, and enforce the requirements of the SSS WDRs.

IT IS HEREBY ORDERED THAT:

Pursuant to the authority delegated by Water Code section 13267(f), Resolution 2002-0104, and Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

B. NOTIFICATION REQUIREMENTS
Although Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) staff do not have duties as first responders, this MRP is an appropriate mechanism to ensure that the agencies that have first responder duties are notified in a timely manner in order to protect public health and beneficial uses.

1. For any Category 1 SSO greater than or equal to 1,000 gallons that results in a discharge to a surface water or spilled in a location where it probably will be discharged to surface water, either directly or by way of a drainage channel or MS4, the enrollee shall, as soon as possible, but not later than two (2) hours after (A) the enrollee has knowledge of the discharge, (B) notification is possible, and (C) notification can be provided without substantially impeding cleanup or other emergency measures, notify the Cal OES and obtain a notification control number.

2. To satisfy notification requirements for each applicable SSO, the enrollee shall provide the information requested by Cal OES before receiving a control number. Spill information requested by Cal OES may include:
i. Name of person notifying Cal OES and direct return phone number. ii. Estimated SSO volume discharged (gallons).
iii. If ongoing, estimated SSO discharge rate (gallons per minute). iv. SSO Incident Description:
a. Brief narrative.
b. On-scene point of contact for additional information (name and cell phone number). c. Date and time enrollee became aware of the SSO.
d. Name of sanitary sewer system agency causing the SSO. e. SSO cause (if known).
v. Indication of whether the SSO has been contained.
vi. Indication of whether surface water is impacted.
vii. Name of surface water impacted by the SSO, if applicable. viii. Indication of whether a drinking water supply is or may be impacted by the SSO. ix. Any other known SSO impacts.
x. SSO incident location (address, city, state, and zip code).

3. Following the initial notification to Cal OES and until such time that an enrollee certifies the SSO report in the CIWQS Online SSO Database, the enrollee shall provide updates to Cal OES regarding substantial changes to the estimated volume of untreated or partially treated sewage discharged and any substantial change(s) to known impact(s).

4. PLSDs: The enrollee is strongly encouraged to notify Cal OES of discharges greater than or equal to 1,000 gallons of untreated or partially treated wastewater that result or may result in a discharge to surface water resulting from failures or flow conditions within a privately owned sewer lateral or from other private sewer asset(s) if the enrollee becomes aware of the PLSD.

C. REPORTING REQUIREMENTS

1. CIWQS Online SSO Database Account: All enrollees shall obtain a CIWQS Online SSO Database account and receive a “Username” and “Password” by registering through CIWQS.

These accounts allow controlled and secure entry into the CIWQS Online SSO Database.

2. SSO Mandatory Reporting Information: For reporting purposes, if one SSO event results in multiple appearance points in a sewer system asset, the enrollee shall complete one SSO report in the CIWQS Online SSO Database which includes the GPS coordinates for the location of the SSO appearance point closest to the failure point, blockage or location of the flow condition that caused the SSO, and provide descriptions of the locations of all other discharge points associated with the SSO event.

3. SSO Categories
i. Category 1 – Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:
a. Reach surface water and/or reach a drainage channel tributary to a surface water; or b. Reach a MS4 and are not fully captured and returned to the sanitary sewer system or not 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 groundwater infiltration basin (e.g., infiltration pit, percolation pond).
ii. Category 2 – Discharges of untreated or partially treated wastewater greater than or equal to 1,000 gallons resulting from an enrollee’s sanitary sewer system failure or flow condition that does not reach a surface water, a drainage channel, or the MS4 unless the entire SSO volume discharged to the storm drain system is fully recovered and disposed of properly.
iii. Category 3 – All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition.

4. Sanitary Sewer Overflow Reporting to CIWQS - Timeframes i. Category 1 and Category 2 SSOs – All SSOs that meet the above criteria for Category 1 or Category 2 SSOs shall be reported to the CIWQS Online SSO Database:

SSMP Audit
Summary
The California State Water Resources Control Board (“SWRCB”) promulgated a waste discharge requirement (“WDR”) permit on May 2, 2006 to regulate sanitary sewer systems. This permit is known as SWRCB Order No. 2006-0003, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. On July 30, 2013, Attachment A to the Order was promulgated and became effective on September 9, 2013 and is known as Attachment A, SWRCB Order No. WQO 2013-0058-EXEC, amending the Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (together these documents constitute the “SSS WDR”).

This permit, among other things, requires local public sewer collection system agencies, referred to as “Enrollees,” to develop a Sewer System Management Plan (“SSMP”).

SSMPs must be self-audited at least every two (2) years and updated every five (5) years from the original adoption date by the Enrollee’s governing board. The original SSMP must have been approved by the governing board of the Enrollee at a public meeting and adopted.

The five-year SSMP update must also be approved and certified as do all significant updates to the SSMP. The SSMP, all references in the document, and the adoption documents by the governing board must be available on the agency website or submitted to the SWRCB upon adoption or recertification. Enrollees do not send their SSMP to the State or Regional Water Boards for review or approval, but must make it publicly available, and upload an electronic copy to the SSO database or provide a link to the Enrollees’ website where the SSMP is posted.

This triennial audit of the City of Montebello’s SSMP consists of sufficiency rankings on all 11 sections of the SSMP requirements. The ranking is explained in the Audit of the SSMP section and is based on information available referenced to the WDR requirements. A total of 7 of the 11 audit elements were found to be in compliance in the sufficiency ranking with 2 elements found to be in partial compliance, 1 element in marginal compliance and 1 element in marginal and partial compliance.

The SSMP Audit Report measures compliance with the Sanitary Sewer System Wastewater Discharge Requirements (SSSWDR) Orders and the effectiveness of the City’s implementation of the current SSMP.

The findings of this audit will be used to gauge the performance of the next triennial SSMP Audit.

Introduction
On May 2, 2006, the California State Water Resources Control Board adopted Order No. 2006-0003 (State Order) to create an equitable statewide mechanism to manage all publicly owned wastewater collection agencies with more than a mile of pipeline, to reduce the number and severity of Sanitary Sewer Overflows (SSOs), and to set up a central depository for online reporting of SSOs when they do occur. On July 30, 2013, Attachment A to the Order was promulgated and became effective on September 9, 2013 and is known as Attachment A, SWRCB Order No. WQO 2013-0058-EXEC, amending the Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (together these documents constitute the “SSS WDR”).

A principal element of the State Order is the requirement that the collection agencies adopt and maintain a management plan for the system, referred to as a Sewer System Management Plan or SSMP.

The City of Montebello, after conducting a public hearing, adopted in accordance with the State Order.

The State Order establishes the following goals:
• The SSMP must document the organization’s legal authority to achieve the goals of the SSMP as demonstrated through City of Montebello’s ordinances, agreements and other legally binding instruments.
• The SSMP must identify the City of Montebello organization and staff responsible for implementing and maintaining the SSMP.
• The SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the City of Montebello wastewater conveyance system.

Additionally, the State Order requires City of Montebello staff perform periodic internal audits of the SSMP focusing on evaluating the effectiveness of the SSMP and staffs’ compliance with its requirements, as shown in Section D-13 of the State Order. The internal audits must be performed at least every three (3) years with the audit report kept on file at City of Montebello.

The SSMP must be updated every six (6) years, must contain any significant program changes, and be re-certified by the City of Montebello. To complete the re-certification process, City of Montebello staff must enter the information on the Online SSO Database and mail a hard copy to the State Water Resources Control Board.

As described below, there are 11 major categories in the SSMP and over thirty-six subcategories. Additionally, a comprehensive audit program includes evaluation elements such as document control, training, objectives, data management, audit

procedures, and results approach outcomes.

This is the internal audit of the SSMP. No action is required by the City of Montebello.

After reviewing and sharing the contents of the audit report, staff will create a list of proposed remedies if deficiencies were found to exist, file the report, and begin working to correct the deficiencies, if any.

3. Legal Authority – State Order D.13.iii
Review the SSMP to determine if it complies with the State Order by having ordinances and agreements in place and updated to prevent illicit discharges, provide for proper design of upstream facilities, provide right of way and access to the system, and enforce City regulations.

Sufficiency: Partial Compliance
Findings: The City of Montebello currently has in place several municipal codes which prevent, require, ensure, limit and enforce specific features and operations required by the Order. The City of Montebello SSMP currently lists the applicable City codes that provide the proper legal authority.

The following are requirements are referenced in the SSMP:
1) The necessary legal authority will prevent illicit discharges into its sanitary sewer system:

The City’s ordinance Title 8, Section 36.030 prohibits the illicit discharges, dumping, and non-storm water discharges into storm water drains. Any person causing an illicit discharge may be required to pay for the cost of clean-up and remediation and Title 8, Section 36.140 which allows criminal penalties for any violations of the Sewer and Industrial Waste Ordinances. Violations for an infraction can be convicted under City Ordinance 8.32.050.
2) Require that sewers and connections be properly designed and constructed:

The City has the responsibility for the review and approval of plans and specifications for the construction and dedication of sanitary sewers, house laterals and sewerrelated appurtenances through the development processes of the Department of Public Works, Development Engineering Division based on the 2019 SSMP. LA County Code Title 20 is utilized for design and construction of new house laterals and construction of collection system. Since the 2019 SSMP, the ownus for overseeing and approving design and construction of connections and sewers is now Community Development.
3) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency:

The City Code, 12.02.280 gives the city the legal right to set requirements to allow unrestricted maintenance access to the public sewer collection system located in the easements. Per the 2019 SSMP, an easement agreement has not been established for any portion of the lateral owned outside of the easement. 4) Limit the discharge of Fats, Oils, Grease (FOG) and other debris that may cause

blockages.

The City by adopting the California Plumbing Code per Section 15.20.010 of the City Municipal Code and LA County Code, Title 20 to be adopted by the City, has the legal authority to satisfy this element of the WDR. The City is planning to adopt it’s own language for an enforceable FOG program in 2025 SSMP. 5) Enforce any violation of its sewer ordinances.

Violations for an infraction can be convicted under City Ordinance 8.32.050. The City Director of Public Works is empowered to enforce all the requirements in Division 2 – Sanitary Sewers and Industrial Waste of the LA County Code and in accordance with Section 20.24.110 of the Code may delegate this authority. The LA County Code, Section 20.24.160 allows criminal penalties for any violations of the Sewer and Industrial Waste Ordinances.

Illicit discharges are addressed in the City of Montebello Municipal Code and found on the City Website:
https://www.municode.com/library/ca/montebello/codes/code_of_ordinances Reference: Legal Authority, City of Montebello SSMP. List of additional City of Montebello Ordinances.

Recommendation: The City of Montebello is in compliance with the Legal Authority requirement of the State Order. However, adopting a FOG program specific for the City of Montebello is being considered working in parallel with updated SSMP.

4. Operation and Maintenance Program – State Order D.13.iv Review the SSMP and activities of staff, consultants and contractors to determine compliance with the State Order by having (a) an up to date collection system map that shows all pipe reaches, manholes, siphons, diversion structures, and pump stations, if any, (b) a routine preventative maintenance program and operations program, (c) rehabilitation and replacement program, (d) operations and maintenance training program, and (e) part inventory program including identification of critical replacement parts.

Sufficiency: In Compliance

SSMP Audit
1) Collection System Mapping
The City of Montebello maintains as-built plans and City Sanitary Sewer Master Plan of the City’s sewer facilities. Data on the plans, such as system location and alignment, pipe material, size, etc., are also stored in the SMD Computer Aided Design Drafting (CADD) system. Information generated by the CADD is printed on Index Map Sheets stored by the City Public Works Department Engineering Division.

These maps are kept at the City Public Works Department, Field Yards. The maps are updated, as necessary, to reflect changes in the system. 2) Resources and Budget
The source of funding for Capital Improvement Program (CIP) is provided thru user fees, property taxes, connection fees and bonds. The CIP is a work in progress as before the program can be identified, the entire system needs to be videotaped and rated.
3) Prioritized Preventative Maintenance
According to the 2019 SSMP, the City is responsible for operation and maintenance of its collection sewer system. The Operation and Maintenance Program has been developed to provide the tools and procedures for maintaining its gravity sewer system, and the City hired sewer contractors possessing adequate knowledge, skills and abilities. The sewer contractors hired by the City will provide after hour services to the City such as Stand-by, callback, and other sewer emergency services. 4) Scheduled Inspections and Condition Assessments
The interior and exterior of manholes are inspected semi-annually for any structural defects, sewage flow condition, presence of vermin or rodents, deleterious industrial waste, odors and any signs of unusual settlement around the manholes and along sewer alignments. Gas traps, manholes and siphons are inspections and cleared of any stoppages or flow restrictions monthly. Sewer lines are cleaned by hydro jet or rodding. Frequency of cleaning is based on inspection records. Sewer lines known to accumulate grease, garbage grinds or sand are put on monthly, quarterly, or semiannual cleaning schedule and those prone to root growth are periodically rodded or chemically treated. City work orders are generated and tracked by the Maintenance Management System (MMS). City field crews activities are recorded in various forms such as service requests, cleaning reports, sewer maintenance daily reports, manhole adjustments, overflow report forms etc. and finally stored in the MMS. 5) Contingency Equipment and Replacement Inventory
The equipment utilized in the maintenance of the City’s sewer facilities is owned by the City contractor. The Contractor has full responsibility for the maintenance and replacement of equipment.

Recommendation: Beginning July 2021, the City retained the Los Angeles County of Public Works for Annual Sewer Maintenance Services to be provided by the Los Angeles County Consolidated Sewer Maintenance District. This contract has been renewed and the Consolidated Sewer Maintenance District now provides maintenance, repairs and infrastructure capital projects. Following this audit, the contract’s maintenance, repair and infrastructure projects will be evaluated for effectiveness.

5. Design and Performance Provisions – State Order D.13.v Review the SSMP to determine if it complies with the State Order by having design and construction standards and specifications for installation of new facilities, including coverage for testing of new facilities prior to acceptance.

Sufficiency: In Compliance
Findings: The SSMP contains reference to the City of Montebello’s Standards and Specifications for new or upgrading facilities, placing the element in compliance. The City requires that all sewers be designed in accordance with Los Angeles County standards.

The LA County DPW has Standard Plans and Specifications for Construction of Sanitary Sewers and appurtenances to insure that sewer lines and connections are properly designed and constructed. The County DPW specifications by reference incorporate the Standard Plans and Specifications for Public Works Construction (Green Book), Special Provisions, and Standard Drawings. The City requires that these publications also be followed in the design of sewer system within the City.

g) An identification of sewer system sections subject to FOG blockages and establish a cleaning maintenance schedule on monthly, quarterly, or semi-annual periodic cleaning schedule.

Reference: Legal Authority, City of Montebello SSMP, Grease Removal Devices Recommendation: The City of Montebello is marginally in compliance with the requirement of this State Order. The City needs to conduct an investigation of “hot spots” caused by FOG, contain a public education element and enforce FOG program requirements.

The City proposed a FOG control program which was not adopted. The FOG program needs to consist of focused cleaning and maintenance as well as source control. The following subsections discuss identification and cleaning of grease-prone areas, legal authority to prohibit grease discharge or require a grease removal device, facility inspection and public outreach. Areas with several restaurants or grease-producing facilities should be considered likely grease problem areas. SSOs caused by grease should be investigates in food service establishments, high density multi-family dwellings, single family dwellings and food manufacturing facilities. The following is a list of projects that can be developed utilizing a sewer system GIS to inventory and characterize potential sources of FOG:
• Develop a GIS application for the identification of sewer system blockages due to FOG and their potential sources including the following:
• Identify and color code sewer collection lines subject to blockage • Identify and plot all SSOs resulting from FOG blockages. If the source of the grease in a lateral can be identified, the City needs to contact the property owner to notify them of the problem and work with them to clean the lateral. • Perform inspection activities for the grease producing facilities, enforcement authorities, and whether the City has sufficient staff to inspect and enforce the FOG ordinance.

8. System Evaluation and Capacity Assurance Plan (SECAP) – State Order D.13.viii
Review the SSMP to determine if it complies with the State Order by having a Capital Improvement Plan (CIP) that considers (a) Evaluation of those portions of the system that is experiencing SSO discharges due to hydraulic deficiency, (b) Design Criteria commensurate with the system, (c) Capacity Enhancement Measures and steps to address short term and long term CIP goals and an implementation schedule, and (d) Schedule for completion of the necessary things-to-do that were developed in items D.13.viii (a) - (c) above.

Sufficiency: Marginal Compliance
Findings: During the 2011 Sanitary Sewer Master Plan, the system was evaluated, and upgrades were recommended based on these results. The following were addressed in the 2019 SSMP:
1) Evaluation: Action needed to evaluate portions of the Sanitary Sewer System that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency.

The City Public Works Department Engineering Division is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized and easily maintainable. Public Works Utilities Division also provides a supportive role in reviewing all proposed sewer plans for new developments in the City to ensure that they conform to County design standards and particularly to ensure that LA County Sanitation District’s requirements for acceptability of treatment. 2) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation to establish appropriate design criteria.

The City’s Public Works Department Engineering Design Guidelines and Sanitary Sewer Master Plan establish design guidelines for private development and public projects within the City of Montebello. The Sewer Master Plan identifies design criteria for new sewer systems including flow factors, peaking factors, hydraulic friction factors, minimum slopes, and maximum allowable depth of flow.
3) Capacity Enhancement Measures: The steps needed to establish a long-term CIP to address identified hydraulic deficiencies including prioritization, alternatives analysis, and schedules.

The collection system capacity enhancement program is a combined effort of City Public Works Engineering Division. The City programs to optimize the use of available sewer capacity and preventing SSO include the CCTV program to identify pipe segments needing repair or with I/I or tree root intrusion problems, sewer cleaning program and

SSMP Audit
the CIP program to effect repairs or replacement of damaged pipes. 4) Schedule: Develop a schedule of completion dates for all portions of the CIP to be reviewed and updated consistent with the SSMP audit and update.

The 2011 Sanitary Sewer Master Plan includes recommended completion dates and fees for the various phases of replacement and rehabilitation. The Engineering Department reviews the CIP on an annual basis and adjusts if necessary to address the most critical issues.

Reference: City of Montebello hydraulic model per Sanitary Sewer Master Plan in 2011, City of Montebello SSMP and Sewer CIP.

Recommendation: City of Montebello needs to CCTV video entire system and create new CIP and Sanitary Sewer Master Plan to reflect short and long term capital improvement projects. All mapping and fee structure needs to be updated in the Master Plan.

9. Monitoring, Measurement, and Program Modification – State Order D.13.ix
Review the SSMP to determine if it complies with the State Order by (a) maintaining relevant information that can be used to establish and prioritize appropriate SSMP activities, (b) monitoring the implementation and, where appropriate, measure the effectiveness of each element of the SSMP, (c) assessing the success of the preventative maintenance program, (d) updating program elements, as appropriate, based on monitoring or performance evaluations, and (e) identifying and illustrating SSO trends, including frequency, location and volume.

Sufficiency: Partial Compliance
Findings:
1) Maintain the relevant information that can be used to establish and prioritize SSMP activities
The SSMP committed to stating that the City will document all relevant data on SSOs that occur in the City including quarterly SSO reports form City PWD, Annual Reports published by the city, Sewer Maintenance Productivity Report and any special reports to regulatory agencies.
2) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP
The evaluation of the City’s SSMP program effectiveness shall be based on key performance indicators of: total number of overflows, overflow response time, reduction in repeated incidents of SSO at same location, total overflows equal to or greater than

Page 629 of 1116 ends

SSMP Audit
18 City of Montebello
SSMP Audit
1,000 gallons or reaching the waters of the United States and reduction in number or overflows that are caused by capacity-related problems. 3) Assess the success of the preventative maintenance program Continually updating or modifying the key elements based on the results of monitoring and responding to SSOs will show the effectiveness of the SSMP. The City shall also make recommendations as necessary to be adjusted or revised within the City boundaries to better serve its residents.
4) Update program elements, as appropriate, based on monitoring or performance evaluations
Monitoring and performance standards are annually evaluated by the Public Works Director and any improvements or modifications to the SSMP program elements are noted and implemented as soon as practical.
5) Identify and illustrate SSO trends including frequency, location and volume The mapping of SSO frequencies are presented in monthly numbers of charts and graphs prepared by the City. The graphs are used to identify SSO trends and evaluate overall program effectiveness. Indicators from these graphs are used as indicators of possible I/I issues and evaluated annually as part of the performance parameters of the SSMP.

Reference: City of Montebello 2019 SSMP
Recommendation: The City of Montebello is in partial compliance with the requirement of this State Order. The City sewer maps shall be regularly updated with every sewer collection system change as often as necessary. A schedule and formal maintenance program for manhole inspections, sewer line cleaning, CCTV inspections shall be fulfilled.

Records to assist in the evaluation of SSMP implementation should be further developed and improved upon.

10. SSMP Program Audits – State Order D.13.x
As a part of the SSMP, City shall conduct periodic audits. At a minimum these audits must occur every three years and a report must be prepared and kept on file. These audits shall focus on the effectiveness of the SSMP, compliance with State Order requirements, identification of any deficiencies and steps to correct them.

Sufficiency: In Compliance
Findings: The City of Montebello has embarked on this audit of its SSMP with timeliness to allow the auditor adequate time to investigate, gather evidence, analyze and then report sufficiency and findings, and finally, to make recommendations when appropriate.

Page 630 of 1116 ends

SSMP Audit
19 City of Montebello
SSMP Audit
The City has conducted the current the SSMP Audit and concurrent SSMP Audit Report at a minimum of every three years and will continue to do so for the next three year deadline occurring in 2028.

Reference: City of Montebello May 2019 SSMP audit
Recommendation: Re-certification of the SSMP is required when significant updates to the SSMP are made. Updates are required every 6 years at a minimum.

The SSMP must be re-certified every 6 years and after updating the SSMP with elements recommended by the 2019 audits together with any program changes.

11. Communication Program – State Order D.13.xi
Review the activities of staff to determine if they have complied with the State Order by (a) communicating the performance of the SSMP with the public, and (b) providing the public and the Los Angeles County Sanitation District the opportunity to provide input.

Sufficiency: In Compliance
Findings: State Order requirements are complex and developing the first SSMP required comments and input from many stakeholders. After the adoption, the SSMP was filed with the City of Montebello for public review. As noted in the State Order, the SSMP Audit is the mechanism to be used to measure SSMP performance and the best document for communicating performance.

Interested parties and the public will have an opportunity to provide input with the completion of each audit every three years and certification every six years as required by the Brown Act (public notice requirements).

Reference: City of Montebello SSMP
Recommendation: It is recommended after each audit that; City staff develop an implementation plan to address any deficiencies identified during the audit. Progress can then be acknowledged with the next audit or certification with the completion of each audit.

City staff will share the audit findings with interested parties and make the report available to the public by posting on the City’s website.

SPILL REPORTING PROCEDURES

MANDATORY PROCEDURES AND REQUIREMENTS

FOR ADDRESSING SPILLS AND OTHER

UNAUTHORIZED DISCHARGES FROM MUNICIPAL

WASTEWATER TREATMENT PLANTS
To protect the public and the environment, pursuant to California Water Code (CWC) Section 13267 and 13383, the Colorado River Basin Regional Water Quality Control Board (Regional Water Board) has established mandatory procedures for handling spills from publicly owned wastewater treatment works (POTWs). These procedures are in addition to existing requirements of your National Pollutant Discharge Elimination System (NPDES) Permit and/or Waste Discharge Requirements, and do not preclude any emergency notification requirements mandated by other regulatory agencies or Federal/State law. Non-compliance with these reporting requirements is subject to potential civil liability according to CWC Section 13268.

These reporting requirements are necessary to ensure proper compliance with your waste discharge requirements and to collect needed information regarding discharges of sewage or other waste that could affect the quality of waters of the state. As the owner of a POTW, your agency is responsible for providing this information pursuant to Water Code sections 13267 and 13383.

WHAT IS A SPILL?
A spill is any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into surface waters or drainage channels that is not permitted or authorized by a regulatory agency. (A spill includes an unauthorized discharge to land that poses a public health threat.) WHAT IS THE REQUIRED REPORTING?
In accordance with the requirements of Health and Safety Code section 5411.5, the discharger shall provide notification to the local health officer or the director of environmental health with jurisdiction over the affected water body of any unauthorized release of sewage or other waste that causes, or probably will cause, a discharge to any waters of the state.

In accordance with the requirements of Water Code section 13271, the discharger shall provide notification to the Office of Emergency Services of the release of reportable amounts of hazardous substances or sewage that causes, or probably will cause, a

Page 634 of 1116 ends

discharge to any waters of the state. The California Code of Regulations, Title 23, section 2250, defines a reportable amount of sewage as being 1,000 gallons. The phone number for reporting these releases to the Office of Emergency Services is (800) 852-7550.

POTWs that experience a spill must follow the reporting procedures listed below:

1. NOTIFICATION
Within two (2) hours after becoming aware of a spill, you must notify by telephone the Office of Emergency Services (OES) at (800) 852-7550, the local health department, and your Regional Water Board office at (760) 346-7491. The OES will provide you with a control number for further reference of the subject spill. If the telephone report is made to the Regional Water Board office after normal business hours, leave a message regarding the spill. OES will make any necessary afterhours contact with Regional Water Board staff.

At a minimum, the following information shall be provided to the Regional Water Board:
(a) The location, date, and time of the release.
(b) The water body that received or will receive the discharge. (c) An estimate of the amount of sewage or other waste released and the amount that reached a surface water at the time of notification. (d) If ongoing, the estimated flow rate of the release at the time of the notification. (e) The name, organization, phone number and email address of the reporting representative.

2. CERTIFICATION
As soon as possible, but not later than twenty four (24) hours after becoming aware of an unauthorized discharge of sewage or other waste from its wastewater treatment plant to a water of the state, the discharger shall submit a statement to the Regional Water Quality Control Board by email at
[email protected] . If the discharge is 1,000 gallons or more, this statement shall certify that the State Office of Emergency Services has been notified of the discharge in accordance with Water Code section 13271. The statement shall also certify that the local health officer or director of environmental health with jurisdiction over the affected water bodies has been notified of the discharge in accordance with Health and Safety Code section 5411.5. The statement shall also include at a minimum the following information:
(a) Agency, NPDES No., Order No., if applicable.

Page 635 of 1116 ends

(b) The location, date, and time of the discharge.
(c) The water body that received the discharge.
(d) A description of the level of treatment of the sewage or other waste discharged. (e) An initial estimate of the amount of sewage or other waste released and the amount that reached a surface water.
(f) The Office of Emergency Services control number and the date and time that notification of the incident was provided to the Office of Emergency Services. (g) The name of the local health officer or director of environmental health representative notified (if contacted directly); the date and time of notification; and the method of notification (e.g., phone, fax, email).” Should there be any conflict between the existing reporting requirements contained in the Monitoring and Reporting Program (MRP) or corresponding orders and this modification, the modification will prevail. All other provisions of your MRP remain in full force and effect.

Overflow Emergency Response Plan
Appendix 6-G Methods for Estimating Spill Volume
A variety of approaches exist for estimating the volume of a sanitary sewer spill. This appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available.

Method 1 Eyeball Estimate
The volume of small spills 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 spill islarger 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 approximately 200 gallons.

Method 2 Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume.

Step 1 Sketch the shape of the contained sewage (see figure above).

Step 2 Measure or pace off the dimensions.

Step 3 Measure the depth atseveral locations and select an average.

Step 4 Convert the dimensions, including depth, to feet.

Step 5 Calculate the area in square feet using the following formulas:

Rectangle: Area= length (feet) x width (feet)
Circle:

Triangle:

Area= diameter (feet) x diameter (feet) x 0.79
Area= base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet.

Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons Method 3 Duration and Flowrate
Calculating the volume oflarger spills, 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 spill and the flowrate. The methods of estimating duration and flowrate are:

Page 638 of 1116 ends

D11ratioll: The duration is the elapsed time from the time the spill started to the time that the flow was restored.

Start Time: The start time issometimes difficult to establish. Here are some approaches:
• Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time. • Changes in flow on a downstream flowmeter 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 during the spill event with flow data from prior days. • Conditions at the spill site change over time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids fonn a light-colored residue.

After a few weeks to a month, the sewage solids tum dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process.
• It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall.

E11d Time: The 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 flowmeters.

Flowrate: The flowrate is the average flow that left the wastewater collection system during the time of the spill.

There are three common ways to estimate the flowrate:
• The San Diego Manhole Flowrate Chart: This chart, included as Appendix 6-F, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting the basis for the flowrate estimate.
• Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill.
• Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection.

For example:
22 upstream connections x 9 gallons per hour per connection = 198 gallons per hour/ 60 minutes per hour
= 3.3 gallons per minute
Spill Volume: Once duration and flowrate have been estimated, the volume of the spill is the product of the duration in hours or days and the flowratc in gallons per hour or gallons per day.

For example:

Spill start time = I I:00
Spill end time = 14:00
Spill duration = 3 hours

3.3 gallons per minute x 3 hours x 60 minutes per hour
= 594 gallons

ITEM # 19

CITY OF MONTEBELLO

CITY COUNCIL AGENDA STAFF REPORT
TO: Honorable Mayor and City Council Members
FROM: Raul Alvarez, City Manager

BY: Cesar Roldan, Director of Public Works
SUBJECT: APPROVE AMENDMENT NO. 1 TO AGREEMENT NO. 3999 WITH

MARK THOMAS FOR ON-CALL ARCHITECTURAL AND

ENGINEERING DESIGN SERVICES
DATE: June 11, 2025
RECOMMENDATIONS:

It is recommended that the City Council:

1. Approve Amendment No. 1 to Agreement No. 3999 between the City of Montebello and Mark Thomas for a One (1) Year Extension; and

2. Authorize the City Manager to execute the Amendment on behalf of the City; and

3. Take such additional, related action that may be desirable.

FISCAL IMPACT:

Mark Thomas & Company, Inc. currently provides citywide on-call architectural and engineering design services to the City of Montebello on an as-needed basis. Staff is recommending the approval and execution of Amendment No. 1 to Agreement No. 3999 (Attachment A), which would extend the term of the agreement by one (1) additional year, through June 30, 2026. The contract’s total not-to-exceed amount will remain unchanged at Two Million Dollars ($2,000,000).

The agreement is administered by the Department of Public Works and is supported through a combination of funding sources, including Measure R, Measure M, Proposition A, Proposition C, and Gas Tax.

Mark Thomas is currently providing engineering support for several active Capital Improvement Projects (CIPs), including the Paving the Way Program – Montebello Boulevard from Los Angeles Avenue to Lincoln Avenue and the Montebello Downtown

CITY COUNCIL AGENDA REPORT - MEETING OF JUNE 11, 2025

Page 2 of 3 ends

Sewer Infrastructure Project. These complex, multi-phase projects require continuity in professional services to ensure successful completion. Extending the agreement will enable Mark Thomas to provide ongoing technical support and project management assistance necessary to close out these and other key infrastructure initiatives.

BACKGROUND/DISCUSSION:

On July 1, 2022, the City of Montebello entered into Agreement No. 3999 with Mark Thomas & Company, Inc. to provide professional on-call engineering services. This agreement was the result of a formal competitive selection process conducted through Request for Proposals (RFP) No. 22-8, which sought qualified consultants to support the City’s CIPs. The original agreement was structured as a three-year term, expiring on June 30, 2025, with the option to extend the contract for up to two additional one-year terms at the City’s discretion.

Since the agreement’s inception, Mark Thomas has consistently delivered high-quality engineering services to the City on an as-needed basis. Their scope of services includes, but is not limited to, civil and structural design, plan review, traffic engineering, cost estimating, and project management support. Notably, the firm has played a significant role in several key CIP projects, such as the Acuna Dog Park and various citywide infrastructure improvements. Given their ongoing involvement and familiarity with the City’s processes, procedures, and project history, the continuity of Mark Thomas’ services is critical to the timely and successful completion of these efforts.

In light of their performance and the continuing need for their services, staff recommend exercising the first one-year extension option as outlined in Section 1 of Agreement No. 3999 (Attachment B). Approval of Amendment No. 1 will formally extend the agreement's term through June 30, 2026, under the same terms and conditions. This extension will ensure that the City retains experienced and capable engineering support as it advances ongoing CIPs.

N/A
ANALYSIS:

SUMMARY:

Staff recommends extension of the term of Professional Services Agreement No. 3999 through June 30, 2026; and authorize the City Manager to execute Amendment No. 1 (Attachment A).

In-House Planning and Design Expertise
Mark Thomas has the unique in-house combination of transportation planning and design services. Our transportation planning and design disciplines are supported by numerous other disciplines in-house, so while subconsultant partners are a value-add to our team structure, we have the unique capability of performing most tasks without the need to outsource.

This experience allows us to develop mobility solutions that are feasible, implementable, and have realistic budgets.

On-Call Experience
Our team of accomplished staff have delivered numerous task orders with a wide range of scopes of work with varied schedules. Whether working on behalf of municipal clients or public agencies, Pat is experienced at advancing multiple efforts concurrently.

Tailored Approach
We tailor our approach to the needs of each task order, attending to the particular challenges, constraints, budget and schedule. We understand how to accommodate the unique needs of each site, and our approach allows us to develop context sensitive designs that address community needs and avoid a “one size fits all” approach.

Public Agency Experience

We have multiple former public employees on staff and they bring thorough understanding of public policies and procedures. We have bid thousands of projects throughout the State and are fully aware of these governing procedures, requirements and laws.

AREAS OF EXPERTISE
Mark Thomas’ areas of expertise are well-matched to meet the City’s needs. We possess strong in-house resources and we have the technical capabilities to provide specialized services to efficiently deliver various types of projects that may arise from this on-call contract. Below are examples of our areas of expertise.

Roadway Improvements
Mark Thomas is recognized as an industry leader in the planning, design, and delivery of roadway and highway improvement projects. Our experience spans from localized widening projects, gap closures, realignments and intersection improvements, to grade separations and arterial reconstructions, as well as Caltrans highway widening and interchanges. We have the expertise to deliver both small localized projects as well as complex highway improvements. We are knowledgeable of local agency design standards, the Standard Plans and Specifications for Public Works Construction (Greenbook), the Caltrans Highway Design Manual (HDM), and the AASHTO. We offer a solid group of experienced professionals in all phases of project delivery, including planning documents, preliminary engineering, and final plans, specifications, and estimates (PS&E).

Traffic Engineering and Transportation Planning
Our team includes recognized experts who have delivered traffic engineering and transportation planning projects for clients throughout Southern California. Our services include working with staff and stakeholders to address residential traffic management concerns, interacting directly with homeowners and their representative associations, commissioners, elected officials and business owners. Our team has extensive experience with transportation planning studies related to system improvements and land development projects. We have worked with many cities to refine their traffic system signal operations and implement traffic calming designs into local roadway reconfigurations and widenings.

Complete Streets/Active Transportation/Trails
Mark Thomas has extensive experience planning and designing complete streets, active transportation corridors and paths and trails for bicycles and pedestrians to connect to key destinations including schools, housing, employment, commercial centers, and other recreational facilities. We have developed the knowledge and expertise essential to designing improvements that facilitate access, connectivity, and safety for all modes of travel. Our Complete Streets projects ultimately facilitate the growth of local businesses and developments while accommodating design elements that appeal to both vehicles and pedestrians. Our designs incorporate NACTO and other Complete Streets guidelines, as well as nationwide best practices and innovations.

ADA Compliance and Design
Mark Thomas excels at integrating ADA compliant practices into all types of roadway, parks, parking lots, and other facilities. We have assisted many local municipalities and even Caltrans in analyzing and achieving ADA compliance. This includes all aspects of design including curb ramps, slopes, and path of travel. Providing detailed elevations and slopes for all grade breaks and critical points is key to eliminating any misinterpretations of the standard plan by the contractor during construction and allowing enough room to accommodate traditional construction tolerances. If selected, we would be preparing curb ramp construction details as necessary, building from the City’s Standards.

Our experience will be invaluable in assessing and prioritizing ADA requirements in any task order, familiarity with ADA standards is critical for any project.

Drainage/Stormwater
We are experienced in the analysis and design of stormwater and drainage facilities. Our task leads have successfully completed numerous projects involving the preparation of hydraulic and hydrology analysis and reports for creeks and pipelines, bridge scour analysis, erosion control plans, and Water Quality Management Plan (WQMP) implementation plans, including most recently drainage/ Low Impact Development (LID) improvements for the Limonite Gap closure in Eastvale. We are capable of designing a wide variety of drainage facilities that include storm drain inlets, storm drain lines, drainage ditches, flood channel grading and modifications, flood control structures, and complex sand filter systems.

Focusing on site-responsive design with the goal of providing specific community improvements, yields a successful project. We have the flexibility to deliver a range of projects such as a detailed complete street planning, streetscape and green street designs, median and gateway enhancements, landscape master plans, and trail designs.

The focus on public infrastructure projects allows our team to understand the regulatory environment and local preferences for landscape and aesthetic design, and to implement these improvements while meeting limited capital budget.

Transit Facilities
Mark Thomas brings the City experience in developing the interface between transit systems, including bus, bus rapid transit (BRT), light rail (LRT) and streetcar, and your city streets. This experience includes the user experience of boarding or crossing the facility, development of stops and stations and corridor-wide transit improvements that enhance the community. We have also provided operation and headquarter facility planning and design to support the systems. Our capabilities also include the review of third-party designs and documentation for implementation of transit systems.

STATE & FEDERAL FUNDING SUPPORT
Mark Thomas has extensive experience managing and designing state and federally funded projects for local agencies. We fully understand the administrative challenges that come along with this funding. We have an unmatched understanding of the Caltrans Local Assistance process gained through delivering more than 100 projects that involved Caltrans Local Assistance coordination. We are intimately familiar with the Caltrans Local Assistance Procedures Manual (LAPM) and Local Assistance Program Guidelines (LAPG) requirements and processes. The LAPM and LAPG are guidelines and instructions for the state and federal programs. These guidelines require compliance with federal and/or state laws, regulations, policies and procedures related to design, right of way acquisition and utility relocation, construction and maintenance.

We also have extensive experience with State-only funding requirements as well. We have recently prepared Senate Bill 1 (SB-1) forms and reports for the City of Corona McKinley Street Grade Separation Project that is funded with Trade Corridor Enhancement Program (TCEP) and Proposition 1B Highway- Railway Crossing Safety Account (HRCSA) funds.

Our recent experience also includes projects funded through the Active Transportation Program (ATP) and Highway Safety Improvement Program (HSIP).

POSITIONING THE CITY FOR FUNDING
We have an in-depth understanding of funding programs and state and federal policies and proven success securing competitive grant funds. We also have extensive planning design experience for complex transportation projects. We have delivered numerous projects requiring grant writing, grant administration, and related services including technical writing and development of narratives, cost benefit analysis, air quality benefit calculations, economic impact analysis, exhibits to support grant applications, cost estimates, requests for authorization, funding, reimbursements, and grant reporting.

We have assisted agencies with the preparation of Active Transportation Program (ATP); Highway Safety Improvement Program (HSIP); Senate Bill (SB 1) programs including Trade Corridor Enhancement Program (TCEP), Local Partnership Program (LPP), and Solutions for Congested Corridors Plan (SCCP); Bicycle Corridor Improvement Program (BCIP); Highway Bridge Program (HBP); California Natural Resources Agency (CNRA) programs; Rebuilding American Infrastructure with Sustainability and Equity (RAISE) Discretionary Grants, and federal discretionary program applications.

Our team is well practiced at analyzing funding opportunities and project financing needs, developing grant narratives and benefit cost analyses, developing exhibits and maps, and coordinating with stakeholders to obtain letters of support. In 2020, we prepared 10 competitive SB-1 applications, 11 ATP applications, and nine HSIP applications. In the past four years, we have secured more than $340 million in transportation funding.

Where Mark Thomas
separates itself from other
firms is we provide both
the in-house technical
writing and engineering
capabilities. Many firms
that only offer grant
funding support services
have to rely on agencies
or other consultants to
prepare the technical
content. Our combination
of grant funding expertise
and project delivery
experience will reduce the
amount of work required
by the City when seeking
funding.

For the County of Orange OC Loop, Segments O, P, Q, Mark Thomas prepared the conceptual plans, helped secure ATP Grant Funding and are now providing the final design services on this $45M project.

Mark Thomas is currently providing the City of Santa Ana with on-call engineering services. Task order projects that Mark Thomas has completed throughout the course of the on-call include:

Standard Avenue Bike Lanes
The City of Santa Ana continues to advance active transportation projects to better serve the community and enhance traffic safety. The Standard Avenue Bikeway Project was developed collaboratively with the community and formalized in the Central Santa Ana Complete Streets (CSACS) Plan. It addresses multimodal mobility needs with high-quality public space improvement.

Mark Thomas is leading the preparation of engineering design plans (PS&E) to right-size and reconfigure two miles of Standard Avenue from Warner Avenue to First Street. The project includes buffered bicycle lanes, separated bikeways, and shared use bicycle routes as well as green conflict striping, crosswalks, and landscaping. The project will include the first protected intersection design within the City at Standard Avenue/McFadden Avenue and continue to anchor Santa Ana as a community that delivers mobility solutions for the residents.

Our team is leading the community engagement, stakeholder coordination, and final design of this important backbone corridor for travel north-south within the City. The future facility provides enhanced connectivity to four parks, four elementary schools, local commercial stores, residential properties, and employment centers. Public engagement has included pop-up tabling events, digital and print media promotion, and one public workshop in July 2021.

Warner Avenue Improvement and Widening Phase I
Mark Thomas is providing design services to the City of Santa Ana for the widening of Warner Avenue, from Main Street to Oak Street. The project will widen the roadway from a four-lane undivided arterial to a six-lane divided arterial to conform to the City and County Arterials Master Plan. The project includes improvements to the Main Street intersection as well as five residential streets. The project also includes landscape improvements and permanent water quality improvement features within the parkway areas. A major component of the project is the installation of drainage infrastructure. The existing storm drainage system carries a major watershed system within a 66-inch RCP. The replacement system will be upsized to a 18-foot by 9-foot reinforced concrete box that will tie into the existing system downstream. Per the City’s direction, we refined the design to include a curb separated Class IV protected bike lane, a first within Orange County. The Class IV will serve to connect to the regional Pacific Electric Bicycle Trail Class I. This has required the evaluation of driveway consolidations in order to provide a more comfortable facility for bicyclists. Due to funding constraints, the project is being delivered on an expedited schedule.

The project includes widening the historic GlendaleHyperion Bridge, realigning Interstate 5 northbound ramps and the Los Angeles River bike path, constructing a new bicycle/pedestrian bridge across the Los Angeles River (bicycle/pedestrian bridge completed in January 2020) and improving bicycle and pedestrian facilities throughout, improving the seismic strength of all six bridges, and upgrading the drainage system and infiltration basins.
7th Standard Road Widening Project, Shafter. The City of Shafter, in coordination with Caltrans District 6, proposes to widen 7th Standard Road from a two-lane highway to a multilane divided expressway in the City of Shafter, City of Bakersfield, and the County of Kern. Mr. Moreno is the project manager overseeing the preparation of the Preliminary Environmental Study, Initial Study/Environmental Assessment, and associated technical studies.

Northwest State Route 138 Corridor Improvement Project, Los Angeles County. Mr. Moreno worked with Metro and consultant team on the preparation of the Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) and Community Impact Assessment and served as the Lead Environmental Planner on the preparation of the Final EIR/EIS through project approval.

The EIR/EIS evaluated corridor alternatives and related operational improvements such as improving sight distances and bringing non-standard roadway features up to current design standards. This project would widen the 36-mile east-west Northwest 138 corridor between Interstate 5 and State Route 14 in the Antelope Valley from two lanes to four and six lanes at various points.

Interstate 405 Sepulveda Pass Widening Project, Los Angeles County. Mr. Moreno worked with the Los Angeles County Metropolitan Transportation Authority (Metro) and the design-build contractor to ensure NEPA/CEQA and regulatory permit compliance, as well as implementation of large-scale mitigation efforts (e.g., wildlife crossing enhancements, revegetation of impacted drainages, and cooperative agreement for transfer of funds to plant trees within the Santa Monica Mountains), as the Lead Environmental Planner for Caltrans District 7 during construction phase. This design-build project involved constructing one 10-mile high-occupancy vehicle (HOV) lane northbound on Interstate 405 from the Interstate 10 to U.S. Highway 101. The work also included adding 10-foot shoulders, restriping all lanes to standard 12-foot widths, realigning existing on-and-off-ramps, reconstructing or modifying 23 bridge and ramp structures, building approximately 18 miles of retaining walls, and performing road improvements on the adjacent city streets.

PROJECT UNDERSTANDING
The City of Montebello is seeking consultant architectural and engineering design services on an on-call basis for projects throughout the City. These projects consist of work related to street, sidewalks, sewer, storm drain, water, landscaping and irrigation, street lighting, traffic signals and city-owned facilities such as parks, parking lots and buildings. Mark Thomas understands that through the on-call contract, the services may include project management, conceptual and final design, third party coordination and permitting, support through the bid and construction phases as well as plan checking services.

Mark Thomas understands that the City has limited staff to deliver the volume of projects in your CIP and is reliant upon these on-call services to do so. We know the key to successfully completing on-call services is to have the depth of staff and to work as an extension of the City’s engineering staff. Mark Thomas stands ready to provide the staff and services needed to support the City. We bring the City a staff of over 300 and have provided a well-rounded team of subconsultants that provides additional depth of resources and expertise to deliver your task orders. With the resources available to Mark Thomas, multiple task orders can be performed concurrently, and with the strength of the task order managers, these tasks will be delivered on time and on budget. We will help you deliver your CIP and meet your commitment to your community.

We will also support the City with staff experienced in reviewing third-party designs from developers or outside agencies that are implementing a project in the City. These projects could include the Montebello Boulevard Grade Separation (San Gabriel Valley Council of Governments), Eastside Light Rail (LA Metro) and the Whittier Narrows Dam (United States Army Corps of Engineers). With our experience, we’ll ensure that the City’s interests and standards are being upheld.

The following work plan represents our general project approach. Mark Thomas will develop a specific work plan for each task order for which we are selected. The key to our approach is to provide the right team for each task. We use a five-step process shown in the figure below to ensure timely and effective response to our client’s requests for on-call services.

STEP 1
Project is identified
requiring the Mark
Thomas team.

STEP 2
Mark Thomas’ project
manager meets
with the City staff to
discuss the project.

STEP 3
Mark Thomas
develops and submits
the scope of work and
fee for the project.

STEP 4
Mark Thomas meets
with the City to review
and finalize the
budget and schedule
requirements.

STEP 5
Upon approval
and receipt of the
Engagement Letter,
our project manager
will mobilize the team
and begin work.

TASK ORDER APPROACH
Our approach to on-call contracts is grounded in our understanding that successful projects, including at the task order level, are a direct result of the following elements:
» A commitment of our most qualified engineering,
design, support staff, and additional resources via
teaming partners as is necessary to deliver every project on time and within budget
» Early identification and resolution of issues
» Acting as an extension of City staff, including always looking out for the City’s best interest
» Being responsive and collaborative in order to meet the needs of the City and the public
» Monitoring design activities and delivery schedules
through a committed Quality Assurance/Quality Control
(QA/QC) process
» Providing direction on the most beneficial and costeffective task order solutions » Open communication and coordination with our clients
Mark Thomas has developed a general approach to a PS&E task order that is described on the following pages. Ultimately, each task order is completed with a tailored approach according to the City’s specific needs, budget, and schedule. For projects with State and/or Federal funding, Mark Thomas will assist the City in the administration and processing of the necessary documents with Caltrans Local Assistance, as discussed further in this Section.

TASK ORDER DELIVERY
Review and Understand the Project
Mark Thomas will gather readily accessible information on the project and will conduct a project site visit during our scope development process where applicable. This will confirm our project understanding and help us answer key technical questions, even before task order notice to proceed (NTP) is received. We will obtain encroachment permits for full access to the project site as one of the first orders of work, along with site specific information, including as-builts and facility maps from pertinent agencies/stakeholders/utility owners, survey data, geotechnical information, and subsurface investigations.

When conflicts such as utilities or potential property impacts are identified during the concept design development, we secure deeds and relevant title-related records to understand liability/risk/costs associated with the impacts. Early pre-concept design identification of constraints provides us with flexibility, allowing for more time to mitigate risks and incorporate cost-effective solutions in the project.

Concept Design Development
If a conceptual design has not been completed at the start of the task order, Mark Thomas will include preliminary design tasks in the scope of work for the project. We will analyze alternatives to determine their relative impacts and prepare preliminary construction cost estimates to assist the City in evaluating each alternative. For each alternative, if needed, we will identify the right of way impacts and address the required environmental clearance and documentation for the project.

We have provided conceptual designs for numerous improvements to enhance mobility, safety, and traffic operations. We recently completed a conceptual design for the Peters Canyon Bikeway Extension and Olive Height Sidewalk Gap Closure for the County of Orange. These designs analyzed potential improvements and developed cost estimates to determine the selected alternative to advance to final design.

Final Design
Generally, when a project reaches the final design phase, all conceptual/preliminary design tasks have already been completed and environmental clearance obtained. At this stage, the Mark Thomas team will verify that there are no elements of the project that require modification due to any updates in design standards or similar requirements that may have occurred between the conceptual design phase and the start of the final design. If there are elements that require modification, we will promptly notify the City to ensure that a collaborative approach can be taken to resolving updates.

During the final PS&E phase, our team will prepare specifications and special provisions based on the local jurisdiction and/or the City’s standard drawings, AASHTO “Greenbook” or Caltrans standard specifications, and other related agency standards if required. A construction cost estimate will be produced for the City, identifying all bid items. Additionally, if a project requires the acquisition of any necessary right of way and or easement, our team can produce legal descriptions, appraisal maps, and right of way maps necessary for any fee takes or temporary construction easements. If the task order was State or Federally funded, we would assist in the ROW certification and RFA packages to receive Caltrans Local Assistance approvals as well as the CTC funding obligation Mark Thomas has provided final design services for a wide variety of improvements including roadway rehabilitations and widenings, ADA curb ramps, sidewalks, bike lanes, intersection modifications, and storm drain facilities. We are currently finalizing the project designs for widening and rehabilitation improvements along Firestone Boulevard in the City of Norwalk and the complete street improvements on Long Beach Boulevard in the City of South Gate.

Construction Phase
At the completion of the final design phase, Mark Thomas will assist the City through the bid and construction phases of the project. We will support the City construction management and inspection crews, providing the following:
» Coordinate bid advertisement
» Provide support during the bid phase
» Prepare bid summary report
» Attend pre-construction meeting
» Conduct field reviews
» Perform shop drawing and submittal review
» Respond to Requests for Information
» Prepare as-built record drawings
If desired, Mark Thomas can provide construction management and administration services, including:
» Resident Engineering services
» Perform construction administration
» Conduct construction inspection
» Provide construction surveys and grade sheet reviews
