Where chipping out of existing manhole base is required to accommodate a new sewer penetration, Contractor shall ensure debris is properly managed and disposed of, an under no circumstances shall debris flow into the existing sewer pipe.
The Contractor shall notify the City Engineer 72 72-hours in advance before any connection is made to existing structures. Work shall be scheduled so that interruption of flow is held to a minimum.
VI-4. TESTING
Prior to acceptance all sewer lines shall be cleaned, tested for leakage by a standard low pressurelow-pressure air or water test, tested for deflection with a mandrel, and inspected by video. All testing shall be performed after all backfill and compaction procedures are complete and prior to street paving. and after all backfill and compaction procedures are complete, streets have been graded and the sub-grade of structural street sections has been compacted and prepared appropriately.
Leakage test is by internal air pressure or water. Infiltration test is by measurement of rate of flow of water. Each section of pipe between manholes, along with the manholes, shall be tested. Use the air test where the difference in elevation between the invert of the upper structure and the invert of the lower structure is more than 10 feet.
Testing procedures shall be as outlined herebelow:
A. Air Test Procedure
Each section of sanitary sewer between two successive manholes shall be tested by plugging all pipe outlets with inflatable and expandable test plugs. Pressure-relief valves shall be set to limit the internal pipe test pressure to five pounds per square inch gauge pressure (5 psig). Air shall be slowly added until the internal pressure is raised to 4.0 psig. Care shall be taken to guard against the sudden expulsion of a poorly installed plug or a plug that is partially deflated.
The internal pressure of 4 psig shall be maintained for at least two minutes to allow the air temperature to stabilize after which the air supply shall be disconnected and the pressure allowed to decrease to 3.5 psig. The Table below provides the minimum time requirements for a pressure drop to occur from 3.5 psig to 3.0 psig.
Should the test disclose an air loss rate greater than permitted, the contractor shall, at his own expense, locate and repair the defective joints or pipe sections. After the Attachment 1
repairs are completed, the line shall be retested until the air loss rate is less than specified below.
Timetable:
Pipe Size Time
6" 4 minutes
8" 5 minutes
10" 6 minutes 30 seconds
12" 7 minutes 30 seconds
B. Water Test Procedure
Test each section of pipe between two successive structures by closing the lower end of the pipe to be tested and the inlet pipe of the upper structure with plugs or stoppers.
Fill the pipe and structure with water to a point 4 feet above the invert of the open pipe in the upper structure or to a height of 10 feet above the invert of the sewer in the lower structure, whichever gives the least hydrostatic pressure on the lower structure.
The total leakage shall be the decrease in volume of water in the upper structure. The leakage shall not exceed 0.025 gpm per inch of nominal diameter of pipe per 1,000 feet of pipe being tested.
If the leakage is greater than allowed, overhaul the pipe and, if necessary, replace and re-lay until the joints and pipe comply with this test. All Complete tests and any required repairs must be completed before the street over the trench is paved.
C. Test for Infiltration
If, in the construction of a section of the sewer between structures, excessive groundwater is encountered, close the end of the pipe at the upper structure sufficiently to prevent the entrance of water. Discontinue pumping groundwater for at least three days. Then test the section for infiltration. The infiltration shall not exceed
0.025 gpm per inch of diameter per 1,000 feet of main line pipe being tested.
Where infiltration exceeds the maximum acceptable, immediately uncover the pipe and reduce the infiltration to within the maximum acceptable by replacing, re-laying, or encasing the pipe in concrete.
D. Test Procedure - Force mains
See test procedures for water mains Section VII-4.
E. Test Procedure – Manholes
Water-tightness of manholes may be tested in connection with hydrostatic tests of the pipeline or at the time the manhole is completed and backfilled.
Fill the manhole with water to an elevation 1 foot below the bottom of the cone section with a maximum water depth of 20 feet. Plug inlets and outlets with stoppers or plugs Attachment 1
and fill the manhole to the limits indicated above. The maximum allowable drop in the water surface shall be 1/2 inch for each 15-minute period of testing.
Even though the infiltration is less than the maximum acceptable, stop any individual leaks that may be observed.
F. Cleaning
The contractor shall clean all lines with a Wayne-type sewer cleaning ball under hydrostatic pressure and shall apply a mandrel to test for deformation. The mandrel shall be the 9-vane design and sized to 95% of the nominal internal diameter of the pipe. Replace and re-lay until the pipe complies with the mandrel test.
G. Video
All new sewer main installations mustshall be observed inspected by video by the City’s Wastewater Division staff prior and reviewed forto acceptance by the Wastewater Division ManagerCity. Inspections may be scheduled by contacting the Wastewater Collections Supervisor at (805) 227-7200 ext. 6701. The video inspection will be used to check for any defects such as debris in the pipe and manholes, pipe deflection, offset joints, or damaged pipe. All defects will be documented and must be corrected prior to City acceptance and use. The video shall be DVD format and color quality. The video shall have a digital display with a date and pipeline footage as a minimum tape reference. The film must also be clear and legible with adequate lighting.
All videos shall include a written log. The log shall have a legible map and a North arrow. Manholes shall be marked respectively and directional arrows indicating flow shall be shown.
A gauge in front of the camera shall be used to measure the depth of debris or standing water. The maximum tolerance for the depth of standing water is 0.5 inches.
H. Placement and/or Replacement of Road Surfaces
Trench paving shall conform to Standard Detail U-2. New street paving shall conform to Section IV of these specifications.
All testing procedures outlined above must be completed prior to pavement replacement or new street paving. After street paving, all manholes shall be raised to grade and concrete collars shall be installed in accordance with Standard Detail F-3.
The concrete collar shall be stamped to show flow direction of sewer lines connected to the manhole. Prior to acceptance of new sewer lines, the lines shall be thoroughly cleaned once again.

From: Jonathan Stornetta, Fire Chief
Subject: Approval of Termination of Local Emergency Regarding January 2023 Storms CEQA Determination: Termination of the local emergency is not a project subject to the California Environmental Quality Act (State CEQA Guidelines, §§ 15060, subd. (b)(2)-(3), 15378).
Date: May 16, 2023
Facts
1. On January 8, 2023, the President of the United States declared that an emergency exists in the State of California and ordered Federal assistance to supplement State, tribal, and local response efforts due to the emergency conditions resulting from successive and severe winter storms, flooding, and mudslides.
2. On January 9, 2023, the Emergency Services Director for the County of San Luis Obispo issued a Proclamation of a Local Emergency related to severe winter storms and a series of atmospheric river systems that struck California beginning on December 27, 2022, bringing high winds, substantial rainfall, significant flooding, falling debris, downed trees, and widespread power outages.
3. The Acting City Manager approved a local emergency declaration on January 9, 2023.
4. On January 12, 2023, the City Council approved Resolution 23-001, whereby the City Council proclaimed a local emergency regarding January 2023 Storms and ratified the proclamation of a local emergency by the Acting City Manager as the Emergency Services Director.
5. Government Code section 8630, subdivision (c), requires that the City Council terminate a local emergency proclamation “at the earliest possible date that conditions warrant.”
6. The City’s efforts to mobilize local resources, coordinate interagency response, accelerate procurement of vital supplies, and seek reimbursement by the State and Federal governments required a continuance of the January Storms emergency. On March 7, 2023, the City Council approved the continuation of the proclamation of a local emergency regarding the January 2023 Storms The City Council having reviewed the need for continuing the existence of a local emergency and recognizing the requirement under statute to terminate the same at “the earliest possible date that the conditions warrant termination,” now conclude that the current conditions related to the January Storms in the City of El Paso de Robles warrant termination of the local emergency proclaimed pursuant to Resolution No. 23-001.
Options
1. Take no action;
2. Approve the Termination of Local Emergency regarding January Rain, Flood, and Windstorm Events;
3. Amend or modify the resolution as submitted;
4. Provide alternative direction to staff.
Analysis and Conclusion
The proclamation of a local emergency was necessary due to:
The severe rain, wind, and flooding conditions that occurred on Monday, January 9, 2023 and Tuesday, January 10, 2023;
The known and unknown damages sustained to public infrastructure and facilities, as well as private businesses and residences;
The anticipated cost to restore City infrastructure and facilities to pre-storm conditions for the safety and health of the public;
The ability of the City to maximize reimbursement from state and federal sources for eligible costs incurred for storm response;
The potential for private property owners and business owners to obtain insurance reimbursements for damages and/or losses; and
The weather forecast that indicates additional storms may impact the City of Paso Robles within the immediate future.
Recognizing the requirement under statute to terminate the local emergency at “the earliest possible date that the conditions warrant termination,” now conclude that the current conditions related to the January Storms in the City of El Paso de Robles no longer are present and warrant termination of the local emergency proclaimed pursuant to Resolution No. 23-001.
Fiscal Impact
There is no fiscal impact by terminating the local emergency. However, costs associated with the City’s emergency response and infrastructure damage are estimated to be approximately one million dollars. The city is working with local, state, and federal agencies to receive maximum reimbursements for response, mitigation, and recovery costs.
CEQA Determination
The City finds that the action to terminate the local emergency is not a project subject to the California Environmental Quality Act (“CEQA”) because the termination of the local emergency in itself has no potential to result in either a direct, or reasonably foreseeable indirect, physical change in the environment. (State CEQA Guidelines, §§ 15060, subd. (b)(2)-(3), 15378.)

Date: May 16, 2023
Facts
1. On March 1, 2023, under the provisions of Government Code section 8558(b), Governor Newsom proclaimed a State of Emergency due to conditions caused by the recent storms, by reason of their magnitude, and likelihood to extend beyond the control of the services, personnel, equipment, and facilities of any single local government.
2. Th City of Paso Robles and the Central Coast region were significantly impacted by rain, flood, and wind events on Friday, March 10, 2023.
3. As a result of existing and expected impacts of the atmospheric river hitting Paso Robles, on March 13, 2023, the City Council approved Resolution 23-026, whereby the City Council proclaimed a local emergency regarding March 2023 Storms and ratified the proclamation of a local emergency by the City Manager as the Emergency Services Director.
4. Government Code section 8630, subdivision (c), requires that the City Council terminate a local emergency proclamation “at the earliest possible date that conditions warrant.”
5. The City Council having reviewed the need for continuing the existence of a local emergency and recognizing the requirement under statute to terminate the same at “the earliest possible date that the conditions warrant termination,” now conclude that the current conditions related to the March 2023 Storms in the City of El Paso de Robles warrant termination of the local emergency proclaimed pursuant to Resolution 23-026.
Options
1. Take no action;
2. Approve the Termination of Local Emergency regarding March 20223 Storms;
3. Amend or modify the resolution as submitted;
4. Provide alternative direction to staff.
Analysis and Conclusion
The proclamation of a local emergency was necessary due to:
The severe rain, wind, and flooding conditions that occurred on Thursday, March 10, 2023; The known and unknown damages sustained to public infrastructure and facilities, as well as private businesses and residences;
The anticipated cost to restore City infrastructure and facilities to pre-storm conditions for the safety and health of the public;
The ability of the City to maximize reimbursement from state and federal sources for eligible costs incurred for storm response;
The potential for private property owners and business owners to obtain insurance reimbursements for damages and/or losses; and
The weather forecast that indicates additional storms may impact the City of Paso Robles within the immediate future.
Recognizing the requirement under statute to terminate the local emergency at “the earliest possible date that the conditions warrant termination,” now conclude that the current conditions related to the January Storms in the City of El Paso de Robles no longer are present and warrant termination of the local emergency proclaimed pursuant to Resolution 23-026.
Fiscal Impact
There is no fiscal impact by terminating the local emergency. However, cost associated with the City’s emergency response and infrastructure damage is estimated to be approximately $200,000. The City is continuing to work with local, state, and federal agencies to explore reimbursements for response, mitigation, and recovery efforts, but it is unlikely the City will see any reimbursements related to the March storms.
CEQA Determination
The City finds that the action to terminate the local emergency is not a project subject to the California Environmental Quality Act (“CEQA”) because the termination of the local emergency in itself has no potential to result in either a direct, or reasonably foreseeable indirect, physical change in the environment.

Subject: Sole Source Authorization for Advanced Metering Infrastructure CEQA Determination: The City finds that this action is not a project under the California Environmental Quality Act pursuant to State Guidelines Section State CEQA Guidelines, §§ 15060, subd. (b)(2)-(3), 15378.
Date: May 16th, 2022
Facts
1. The City provides water and wastewater service for all homes, businesses, and institutions in the City.
Potable water is delivered to the City’s water customers through approximately 10,935 metered service connections.
2. The City’s water and wastewater charges are based on actual water consumption. Therefore, the City relies on accurate and timely water meter reading information for the billing and collection of approximately $28 million in annual revenue.
3. The City currently uses a third-party vendor to read customer’s water meters. Each meter is read manually each month by vendor employees physically visiting all meter locations throughout the City.
4. Over the past two years, the time between meter readings has varied significantly on account of vendor staffing issues. These delays have caused customer frustration and confusion regarding billings for water and sewer service, have increased staff time to adjust billings and assist customers, and have delayed collection of revenue Water and Wastewater fund revenues.
5. The City’s Capital Improvement Program in the City’s adopted budget includes a project to retrofit existing water meters to advanced metering infrastructure (AMI) beginning this year. AMI is an integrated system consisting of electronic meter registers, a communications network, and data management system that collect water consumption data without requiring manual reading by visiting each meter.
6. The City’s Purchasing Policy Section 5.0, Sole Source Vendors, states that quotation and bid requirements may be waived when the City is best served by a particular vendor. It further states that sole source justification includes, but not limited to, the replacement part for a specific piece of equipment (e.g., a Ford engine for a Ford vehicle); or consistent with current inventory (e.g., all police cruisers being the same make/model).
7. The Water Department has evaluated AMI alternatives that are compatible with the City’s existing water meters and has piloted a cellular AMI solution provided by Badger Meter Company (Badger) for the past three months. Badger provides conventional water meters and AMI solutions.
8. The City has long been standardized on Badger water meters for all meters 2 inches and smaller, which represents a large majority of the City’s active water meters.
9. Badger has developed a product for their existing meters that allows agencies to convert to AMI by replacing only the meter register, forgoing the need to replace the entire meter body. Foregoing replacement of the meter body will reduce the cost of AMI implementation.
10. The Badger Orion AMI system is directly compatible with approximately 96% of the City’s active water meters, is provided by a well-established water meter vendor that has provided reliable service to the City for more than a decade and provides cost-effective equipment for conversion to AMI.
11. Staff is recommending that the City authorize sole source procurement of Badger AMI equipment and services. This authorization will allow staff to:
- Continue preparation for the AMI Retrofit Project and move toward developing bid documents for installation of AMI equipment on the City’s existing water meters. - Establish an agreement and long-term pricing for the selected AMI system. - Begin integration of the AMI data management system with the City’s utility billing system Options
1. Take no action;
2. Authorize sole source procurement from Badger Meter Company for the Orion/Beacon AMI system;
3. Provide alternative direction to staff.
Analysis and Conclusions
The City currently contracts with a third-party vendor for monthly reading of the City’s approximately 10,935 active water meters and requires timely meter readings for customer billing, calculation of customers’ sewer usage, and water demand estimates. Recently there have been extensive delays in meter reading on account of the vendor’s staffing issues. For example, in early 2022, meter readings were significantly delayed for five consecutive months. These delays impacted the City’s water customers and required additional staff time to make necessary adjustments to billings, assist other customers with questions and concerns over variations in billings, and provide re-reads. Additionally, the vendor has indicated that they are not sure how long their business will continue operating.
The Water Department has planned for conversion to AMI metering and has budgeted for conversion of the City’s existing meters to an AMI solution. Benefits of AMI include:
- Improved timeliness and consistency for meter readings. - Customers can access water usage data and customize alerts for high water use thresholds. - Rapid leak detection and notification will reduce water losses and save customers money. - Improved customer service and customer assistance.
- Meter tampering alerts.
- Improved distribution system operation and demand projection. - Identification of backflow events, providing greater protection of public health. - Lower monthly meter reading costs.
- Significantly reduced vehicle trips for meter reading and re-reads.
Approximately 96.4% of the City’s water meters are directly compatible with the Badger Orion AMI system.
Therefore, most of the City’s existing meters can be cost-effectively converted to the Badger Orion AMI system because the meter bodies themselves do not have to be removed, replaced, and reconnected to the City and customers’ service lines.
The Water Department has evaluated other AMI product offerings and identified the Badger Orion cellularbased AMI solution and Beacon data management system as the best approach to meeting the City’s needs.
The Badger Orion system can be installed without requiring replacement of existing meter bodies. The system uses a cellular network that does not require the City to build or maintain a fixed network of communication antennas to transmit data throughout the City. Badger’s user interface is the most evolved and user friendly for both the utility and individual customers. Further, the Badger Orion AMI system is provided by Badger Meter Company, an established manufacturer of water meters that has a proven track record and has reliably served the City for more than a decade The Water Department has also successfully piloted the Badger Orion AMI system on water meters throughout the City over the past three months and, using Badger’s “Beacon” data management system, received timely meter reads during this time. Additionally, during the pilot, several water leaks were identified almost immediately, and the City was able to alert customers of the issues so they could be corrected. Even small leaks that would normally go undetected are easily identified and flagged by the system.
In contrast, with monthly meter reading, high usage is not detected until near the end of the month, when a significant amount of water loss and expense has already occurred.
Staff have received budgetary pricing for implementation of the AMI retrofit project. The pricing includes hardware costs for the AMI encoder registers that will be installed on existing customer meters, costs for implementation of the data management and analytics software (Beacon), and integration with the City’s existing billing system which generates customer bills.
City Council’s authorization for sole source procurement of the Badger AMI system equipment and services will allow City staff to continue progressing the City’s AMI project including working with the AMI provider to establish an agreement and formal pricing for the AMI hardware, software and data management service (Beacon), and integration with the City’s billing system; and move toward developing bid documents for installation of AMI equipment on the City’s existing water meters. The City would also update fees associated with meter installations provided by the City for new development, preventing newly established services from needing to be retrofitted at a later date.
Fiscal Impact
Authorization for sole source procurement of the Badger Orion AMI system does not have any immediate fiscal impact. However, implementation of the AMI system will involve payment of fees for set-up of the data management system (Beacon), integration with the City’s utility billing system, purchase of AMI equipment from Badger Meter Company, and payment of an ongoing service fee. The City’s Capital Improvement Program in the City’s approved budget includes budget for implementation of the AMI project. Additionally, the City is also pursuing a grant opportunity through a State Water and Efficiency Grant Program.
Recommendation (Option 2)
Approve standardizing on the Badger Orion AMI system provided by Badger Meter Company and sole source procurement from Badger for AMI equipment and associated data management services.

APPROVING STANDARDIZING ON THE BADGER ORION AMI SYSTEM AND SOLE
SOURCE PROCUREMENT FROM BADGER METER COMPANY FOR AMI EQUIPMENT AND
ASSOCIATED DATA MANAGEMENT SERVICES
WHEREAS, the City provides water and wastewater service for nearly all homes, businesses, and institutions in the City; and
WHEREAS, the City currently uses a third-party vendor to read customer’s water meters. The contract meter reader’s staff manually reads meters each month by visiting all meter locations throughout the City; and
WHEREAS, the level of service provided by the City’s third-party vendor for meter reading has recently declined and significant delays have occurred in meter readings for consecutive months; and WHEREAS, the Capital Improvement Program in the City’s adopted budget includes a project to retrofit existing water meters to advanced metering infrastructure (AMI) beginning in 2023; and WHEREAS, the City has evaluated AMI alternatives that are compatible with the City’s existing water meters and has piloted a cellular AMI solution provided by Badger Meter Company (Badger); and WHEREAS, the City has standardized on meters manufactured by Badger for all water meters two inches and smaller; and
WHEREAS, an AMI system provided by Badger is directly compatible with approximately 96% of the City’s active water meters and is a cost-effective alternative for conversion to AMI that meets the City’s needs for conversion to AMI; and
WHEREAS, authorization of sole source procurement of AMI equipment and services will allow the City to continue preparation for the City’s AMI project to retrofit existing manually-read water meters to AMI, which includes establishing an agreement and long-term pricing for the selected AMI system, integration of the AMI data management system with the city’s utilities billing system, and procurement of AMI meter equipment for new meters being installed in the distribution system.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF EL PASO DE ROBLES DOES HEREBY RESOLVE AS FOLLOWS:
Section 1. All of the above recitals are true and correct and incorporated herein by reference.
Section 2. The Council finds that the standardization on Badger AMI equipment is in the best interest of the City and the community because:
The Badger Orion system can be installed without requiring replacement of existing meter bodies; The system uses a cellular network that does not require the City to build or maintain a fixed network of communication antennas to transmit data throughout the City; Badger’s user interface is the most evolved and user friendly for both the utility and individual customers;
The Badger Orion AMI system is provided by Badger Meter Company, an established manufacturer of water meters that has a proven track record and has reliably served the City for more than a decade.
Attachment 1
Section 3. Based upon all of the facts and evidence in the record, the City Council hereby approves the standardization of advanced metering infrastructure equipment from Badger Meter Company and the sole source procurement of equipment and services from Badger Meter Company for advanced metering infrastructure.
