CITY COUNCIL
REPORT 9K

DATE: SEPTEMBER 20, 2022
TO: MAYOR AND COUNCIL MEMBERS
FROM: SANJAY MISHRA, PUBLIC WORKS DIRECTOR
SUBJECT: ADOPTION OF SANITARY SEWER MASTER PLAN 2022
___________________________________________________________________

RECOMMENDATION
City staff recommends that the Council adopt a resolution approving the Sanitary Sewer Master Plan 2022.

BACKGROUND
The City owns and operates approximately 50 miles of sewer pipelines and 2 sewage lift stations. This system collects and conveys wastewater generated at residential, commercial, and industrial buildings to the City’s wastewater treatment plant.

The wastewater collection system must be sized and have sufficient capacity for wastewater flows from both existing and planned development, as well as the ability to accommodate increased flows that occur during the wet season. Adequate operation and maintenance must be performed on the system to protect public health, safety, and the environment. Lack of or deferred maintenance can result in cumulative effects including but not limited to blockages and sanitary sewer overflows.

To achieve the goals above and effectively manage the wastewater collection system, the City relies upon its Sanitary Sewer Master Plan (SSMP), which was developed in 2008. If warranted, the SSMP should be updated to reflect new information, new operating procedures, and to evaluate the existing system for its structural integrity and determine where capacity deficiencies may exist.

The City’s wastewater collection system is aging with some segments over 50 years old. Several studies and our historic records show that our collection system experiences high levels of inflow (when stormwater enters the sewer system through rain leaders or drains illegally connected to the sewer system) and infiltration (when groundwater seeps into sewer pipes through cracks or deteriorated manholes) (I/I).

In response, the Regional Water Quality Control Board has included in our current operating permit a condition that the City inspect the condition of all pipes with an inpipe camera by March 31, 2023 (the City is in the process of inspecting all pipes and City Council Report, 9K
September 20, 2022

Page 2 of 3 ends

is on track to complete this task on time). As prior studies have shown, it is expected that the additional inspections will show a broad reaching need to repair or replace many miles of pipe.

REVIEW AND ANALYSIS
Master planning for the sewer collection system is vital for us to be responsive to development, especially the increases in density the State is pushing in response to the housing crisis. Further and of great importance to Pinole, the master planning process will aid in prioritizing capital improvements. This is extremely important when trying to address systemic I/I.

The current SSMP was developed over 14 years ago. This proposed SSMP 2022 will help the City address capacity deficiencies and proactively schedule and prioritize replacement/rehabilitation for segments to reduce inflow and infiltration.

The Council approved to issue a Request for Proposals for the Master Plan on May 19, 2020, which was posted to www.publicpurchase.com, an electronic bidding platform. We received one proposal. The proposal was deemed complete. The proposal was submitted by Carollo Engineers. City council approved the contract award on September 1, 2020, to Carollo engineers to complete the Sanitary Sewer Master Plan 2022 for a not to exceed amount of $449,000.

The updated Sanitary Sewer Master Plan 2022 includes:

1. Realistic growth projections for use in collection system capacity evaluations.

2. Identifies and quantifies I/I, provides best approach to mitigate system inefficiencies.

3. Provides collection system hydraulic models.

4. Identifies capital improvements to provide for system expansion while optimizing the life of existing collection system assets.

5. Balancing capital improvements and maintenance programs to maximize taxpayer investment and provide the level of service that ratepayers expect.

Consistency with Strategic Plan
The Council has already declared its support of the efforts of this master planning process through the adoption of the City of Pinole Strategic Plan. This planning effort supports the following components of the Strategic Plan:

Goal 1 Safe and Resilient Pinole
Strategy 1 Conduct citywide asset condition assessment
Goal 2 Financially Stable Pinole
Strategy 5 Develop a disciplined approach to funding infrastructure maintenance and improvements
City Council Report, 9K
September 20, 2022

Page 3 of 3 ends

Goal 3 Vibrant and Beautiful Pinole
Strategy 2 Develop/create a comprehensive strategy to encourage streamlining the rehabilitation and reuse of undeveloped or under-developed properties

FISCAL IMPACT
There is no direct fiscal impact for adopting the proposed Sanitary Sewer Master Plan 2022. The Council had previously approved a not to exceed amount of $449,0000 to complete this task. We are within the above approved budget amount and are not seeking any additional funds.

Average dry
weather flow
(ADWF)
Average flow rate or pattern from days without noticeable inflow or infiltration response. ADWF usage patterns for weekdays and weekends differ and must be computed separately. ADWF can be expressed as a numeric average or as a curve showing the variation in flow over a day. ADWF includes the influence of normal groundwater infiltration (not related to a rain event).

Basin
Sanitary sewer collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances. Also refers to the ground surface area near and enclosed by pipelines. A basin may refer to the entire collection system upstream from a flow meter or exclude separately monitored basins upstream.

Depth/diameter
(d/D) ratio
Depth of water in a pipe as a fraction of the pipe’s diameter. A measure of fullness of the pipe used in capacity analysis.

Infiltration and
inflow
Infiltration and inflow (I/I) rates are calculated by subtracting the ADWF flow curve from the instantaneous flow measurements taken during and after a storm event.

Flow in excess of the baseline consists of inflow, rainfall-responsive infiltration, and rainfall-dependent infiltration. Total I/I is the total sum in gallons of additional flow attributable to a storm event.

Infiltration,
groundwater
Groundwater infiltration (GWI) is groundwater that enters the collection system through pipe defects. GWI depends on the depth of the groundwater table above the pipelines as well as the percentage of the system that is submerged. The variation of groundwater levels and subsequent groundwater infiltration rates is seasonal by nature. On a day-to-day basis, groundwater infiltration rates are relatively steady and will not fluctuate greatly.

Infiltration,
rainfall-dependent
Rainfall-dependent infiltration (RDI) is similar to groundwater infiltration but occurs as a result of storm water. The storm water percolates into the soil, submerges more of the pipe system, and enters through pipe defects. RDI is the slowest component of storm-related infiltration and inflow, beginning gradually and often lasting 24 hours or longer. The response time depends on the soil permeability and saturation levels.

Infiltration,
rainfall-responsive
Rainfall-responsive infiltration (RRI) is storm water that enters the collection system through pipe defects, but normally in sewers constructed close to the ground surface such as private laterals. RRI is independent of the groundwater table and reaches defective sewers by way of the pipe trench in which the sewer is constructed; particularly if the pipe is placed in impermeable soil and bedded and backfilled with a granular material. In this case, the pipe trench serves as a conduit similar to a French drain, conveying storm drainage to defective joints and other openings in the system.

Inflow
Inflow is defined as water discharged into the sewer system, including private sewer laterals, from direct connections such as downspouts, yard and area drains, holes in manhole covers, cross-connections from storm drains, or catch basins. Inflow creates a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows. Overflows are often attributable to high inflow rates.

Normalization
To run an “apples-to-apples” comparison amongst different basins, calculated metrics must be normalized. Individual basins will have different runoff areas, pipe lengths and sanitary flows. There are three common methods of normalization.

Depending on the information available, one or all methods can be applied to a given project:

City of Pinole
Sewer Flow Monitoring & inflow/Infiltration Study
V&A Project No. 13-0276 Table of Contents vii
Term Definition
Pipe Length: The metric is divided by the length of pipe in the upstream basin expressed in units of inch-diameter-mile (IDM).

Basin Area: The metric is divided by the estimated drainage area of the basin in acres.

ADWF: The metric is divided by the average dry
weather sanitary flow (ADWF).

Normalization,
inflow
The peak I/I flow rate is used to quantify inflow. Although the instantaneous flow monitoring data will typically show an inflow peak, the inflow response is measured from the I/I flow rate (in excess of baseline flow). This removes the effect of sanitary flow variations and measures only the I/I response:

Pipe Length: The peak I/I flow rate is divided by the length of pipe (IDM) in the upstream basin. The result is expressed in gallons per day (gpd) per IDM (gpd/IDM).

Basin Area: The peak I/I flow rate is divided by the geographic area of the upstream basin. The result is expressed in gpd per acre.

ADWF: The peak I/I flow rate is divided by the average dry weather flow (ADWF). This is a ratio and is expressed without units.

Normalization,
GWI
The estimated GWI rates are compared to acceptable GWI rates, as defined by the Water Environment Federation, and are used to identify basins with high GWI:

Pipe Length: The GWI flow rate is divided by the length of pipe (IDM) in the upstream basin. The result is expressed in gallons per day (gpd) per IDM (gpd/IDM).

Basin Area: The GWI flow rate is divided by the geographic area of the upstream basin. The result is expressed in gpd per acre.

ADWF: The GWI flow rate is divided by the average dry weather flow (ADWF).

This is a ratio and is expressed without units.

Normalization,
RDI
The estimated RDI rates at a period 24 hours or more after the conclusion of a storm event are used to identify basins with high RDI:

Pipe Length: The RDI flow rate is divided by the length of pipe (IDM) in the upstream basin. The result is expressed in gallons per day (gpd) per IDM (gpd/IDM).

Basin Area: The RDI flow rate is divided by the geographic area of the upstream basin. The result is expressed in gpd per acre.

ADWF: The RDI flow rate is divided by the average dry weather flow (ADWF).

This is a ratio and is expressed without units.

Normalization,
total I/I
The estimated totalized I/I in gallons attributable to a particular storm event is used to identify basins with high total I/I. Because this is a totalized value rather than a rate and can be attributable solely to an individual storm event, the volume of the storm event is also taken into consideration. This allows for a comparison not only between basins but also between storm events:

Pipe Length: Total gallons of I/I is divided by the length of pipe (IDM) in the upstream basin and the rainfall total (inches) of the storm event. The result is expressed in gallons per IDM per inch-rain.

City of Pinole
Sewer Flow Monitoring & inflow/Infiltration Study
V&A Project No. 13-0276 Table of Contents viii
Term Definition
Basin Area (R-Value): Total gallons of I/I is divided by total gallons of rainfall water that fell within the acreage of the basin area. This is a ratio and is expressed as a percentage. R-Value is described as “the percentage of rainfall that enters the collection system.” Systems with R-Values less than 5%1 are often considered to be performing well.

ADWF: Total gallons of I/I is divided by the ADWF and the rainfall total of the storm event. The result is expressed in million gallons per MGD of ADWF per inch of rain.

Peaking factor
Ratio of peak measured flow to average dry weather flow. This ratio expresses the degree of fluctuation in flow rate over the monitoring period and is used in capacity analysis.

Surcharge
When the flow level is higher than the crown of the pipe, then the pipeline is said to be in a surcharged condition. The pipeline is surcharged when the d/D ratio is greater than 1.0.

Weekend/weekday
ratio
The ratio of weekend ADWFs to weekday ADWFs. In residential areas, this ratio is typically slightly higher than 1.0. In business districts, depending on the type of service, this ratio can be significantly less than 1.0.

ES EXECUTIVE SUMMARY
Scope and Purpose
V&A Consulting Engineers, Inc. (V&A) has completed sanitary sewer flow monitoring with inflow and infiltration (I/I) analysis within the City of Pinole (City). Flow monitoring was performed over a period of approximately 3.5 months from December 13, 2013 to April 1, 2014 at 16 open-channel flow monitoring sites. The purpose of this study was to identify smaller basins within Area Five and Area Six having the highest rates of I/I.

To the extent possible given the time constraints of a single wet weather season and the unpredictable nature regarding the duration and intensity of storm events, V&A attempted to analyze early season rain events, make a decision on areas with high I/I, and then relocate flow meters within the same wet weather season. Relocations between rainfall events intended to further narrow the search for areas of high I/I with an ultimate goal of identifying possible CIP projects in support of the City’s budgeted pipe lining and replacement program.

During the course of Phase 1 of this study, V&A installed 14 flow meters and 2 volumetric meters focused within Area Five and Area Six, dividing these areas into 16 sub-basins. For Phase 2, V&A removed ten Phase 1 meters and redistributed them amongst Basins 3, 5 and 6. A final rain event allowed for a third phase of this study, in which V&A removed seven Phase 1 and 2 meters and reinstalled them within sub-basins 3.1, 5.2, 6.3 and 6.5.

The contents of this deliverable summarize the results of the three aforementioned flow monitoring and I/I phases of this study. Additionally, V&A was asked to analyze and comment on the following items, which are included in this report as additional Appendices:

Flow Split between M6.0A and M6: As a part of Phase 3, the City asked that the flow split between Sites M6.0A and M6.3 be monitored and analyzed during average dry weather and peak wet weather flow conditions.

Allocation of Inflow within the Perimeter of the Treatment Plant: Rain that falls within the perimeter of the treatment plant flows directly into the treatment facility as waste; henceforth, there is an associated cost of treatment. The City asked V&A to determine the volume of inflow that falls within the footprint of the treatment facility.

Treatment Plant Influent Meter: The City has two methods available to measure incoming flows from the City of Pinole. The City requested that V&A analyze the accuracy and determine which method is preferred for flow data reliability. This analysis was important for purposes of billing between the Cities of Pinole and Hercules. V&A dedicated a flow meter to measure the flow into the treatment plant for comparison to the City meter; the results are presented within this deliverable as a Technical Memorandum.

Disclaimer
The following flow monitoring, capacity and I/I results and analyses do not replace a full dynamic hydraulic model. A dynamic model developed by a master planning engineering firm would determine capacity on a node-to-node basis and would be based on pipe slopes of the individual pipe segments within the local collection system. The following data and the interpretation of these data should be used at the discretion of the City Engineer.

d/D Ratio: Nine of the flow monitoring sites (Sites M2, M5, M6, M10, M11, M12, M14, M16 and M6.1) reached surcharge conditions.

Sanitary Sewer Overflow Potential: Given the level of surcharging seen during Storm Event 1, the manholes at Site 6, Site 11/12 and Site 16 have the potential for a sanitary sewer overflow (SSO) during a larger rainfall event. Site 6 has historical precedence for SSO discharging during large rainfall events.

Inflow and Infiltration Analysis Results
Preface
Per discussions with the City, V&A prioritized I/I evaluations on the comparative analysis of the Peak I/I rate, traditionally associated with inflow. Inflow sources transport rain water directly into the sewer system; the corresponding inflow rates are tied closely to the intensity of the storm. This component of RDI/I often causes a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows. Figure ES-1 illustrates the I/I response curve for Basin 3 during Phase 1 as it related to peak I/I rate.

Figure ES-1. I/I Isolation Curve, Basin 3 (Inflow Measurement) V&A analyzed the I/I isolation curves for all sites and all phases of this study to try to determine the areas of the City collection system that had the highest peak I/I rates.

Phase 1 (Large Basin) Results
The results of the Phase 1 flow monitoring and I/I analyses for the larger basins are shown as follows:

Basin 3: The City cited historical data and field observations regarding known I/I issues within Basin 3.

Basin 5: V&A recommended investigating Basin 5 due to the high peak I/I ratios and high combined I/I totals.

Basin 6: There is a known capacity issue one manhole upstream from the Basin 6 monitoring location.

Basin 8: This is a newer area of the City and this area had minimal I/I contribution.

Basin 9: The flow meter was not in an ideal location for monitoring. The consensus was that the response for Basin 9 was real and considerable but the magnitude may not be correct due to metering conditions.

Basin 11: This location had significant peak I/I rates and combined I/I totals.

Basin 12: The metering manhole for this basin surcharged with evidence that the surcharge was close to an SSO.

Basins 15/16: Both basins were noted for generally high I/I rates and total I/I contribution.

Old Henry Road: The City cited the age of the sewer system along Old Henry Road and noted this correlation to the high I/I rates within Basins 9, 11 and 12.

Final group conclusions were as follows:

Focus additional phases of monitoring within Basins 3, 5 and 6.

The focus of the study moving forward would be to spend the remainder of the 2014 wet weather season identifying smaller high I/I mini-basins within this region for possible future CIP work.

Identifying areas of I/I reduction may help to solve two problems within the City: (1) severe flows observed in Basin 3 (San Pablo Pump Station), and (2) capacity issues observed at the manhole at the intersection of Pinon Avenue and Bay View Farm Road.

Make note of the ‘Old Henry Road’ Basins as a future candidate for a focused flow monitoring and I/I study.

Phases 2 and 3 Focused Sub-Basin Results
Additional phases of flow monitoring and I/I analysis were focused within Basins 3, 5 and 6.

Through focused flow monitoring on a very small basis, V&A was able to find ‘hot-spot’ locations within Basins 3, 5 and 6 that were contributing a significant percentage of the peak. Figure ES-3 illustrates the hot-spot areas within Basins 3, 5 and 6.

Recommendations
V&A advises that future I/I reduction plans consider the following recommendations:

1. Potential CIP Projects for I/I Mitigation and Reduction a. The City should conduct I/I mitigation and reduction measures in the following minibasins:
i. Basin 3-1 iv. Basin 6-3A
ii. Basin 3-1A v. Basin 6-5
iii. Basin 5-2
b. For I/I reduction, V&A recommends rehabilitation of the sewer mains, laterals and side sewers.
i. The most comprehensive study on the percent of I/I reduction has been conducted by King County, Initial Infiltration and Inflow Reduction Project Alternatives Analysis Report. This study confirmed the popular theory that over 50% of infiltration and inflow enters from private lateral connections. The report also makes the following recommendations for I/I mitigation:
(a) CCTV work is best performed during a rainfall event after groundwater levels have begun to rise, allowing visual confirmation of specific I/I entry points, including determining the source of potential lateral I/I source. A generally consistent deficiency was observed with regards to the joint conditions in the laterals and side sewers.
(b) Rehabilitation of sewer mains, manholes, laterals and side sewers results in approximately 80% reduction of I/I.

2. Future I/I Identification – Continued Sub-Basin Flow Monitoring and I/I Analysis: V&A recommends that the City continue to locate and mitigate potential sources of I/I. Already identified as known contributing sub-basins with high volumes of I/I are Basins 9, 11, 12, 14 and 15. It is possible that a study similar to this study may identify CIP projects that can significantly reduce the overall I/I within the City collection system.

3. Other I/I Investigation Methods: Other potential I/I investigation methods include the following:
a. Smoke testing
b. Night-time reconnaissance work to (1) investigate and determine direct point sources of inflow, and (2) determine the areas and pipe reaches responsible for high levels of infiltration contribution.

4. I/I Reduction Cost Effectiveness Analysis: The City should conduct a study to determine which is more cost-effective: (1) locating the sources of inflow/infiltration and systematically rehabilitating or replacing the faulty pipelines; or (2) continued treatment of the additional rainfall dependent I/I flow.

1.0 INTRODUCTION

1.1 Scope and Purpose
V&A Consulting Engineers, Inc. (V&A) was retained by the City of Pinole (City) to conduct sanitary sewer flow monitoring and inflow/infiltration (I/I) analysis within the City of Pinole (City). Flow monitoring occurred over a 3.5-month period from December 13, 2013 to April 1, 2014. Two basins within the collection system (Area Five “The Meadows” and Area Six “Old Town”) had already been identified by the City as having high rates of RDI/I. The purpose of this study was to identify smaller basins within Area Five and Area Six having the highest rates of I/I.

To the extent possible given the time constraints of a single wet weather season and the unpredictable nature regarding the duration and intensity of storm events, V&A would attempt to relocate flow meters within the wet weather season. Relocations between rainfall events could further narrow the search for areas of high I/I with an ultimate goal of identifying possible CIP projects in support of the City’s budgeted pipe lining and replacement program. The outline of the strategies for the I/I investigation is shown as follows:

Phase 1 – Initial Sub-Basins: V&A installed 14 flow meters and 2 volumetric meters focused within Area Five and Area Six, dividing these areas into 16 sub-basins.

Mid-Project, Post-Rainfall I/I Analysis: After the first usable rainfall event, V&A analyzed the flow data for relative I/I contribution and comparison amongst the sub-basins.

Quick Decisions: V&A conveyed the I/I results to the City, making recommendations for targeted investigation of the highest ranking I/I sub-basins.

Maneuverable Metering: V&A removed the meters from the sub-basins with lower RDI/I rates and relocated them into the sub-basins with the higher RDI/I rates, dividing the original sub-basins into mini-basins.

Phase 2 – Focused Sub-Basins: The same process from Phase 1 was repeated for Phase 2, focusing the search within the sub-basins with the greatest I/I contribution.

Phase 3 – Focused Mini-Basins: The rain events of the 2013/2014 season were sufficient to conduct a third phase of flow monitoring and I/I analysis.

Additionally, V&A was asked to analyze and comment on the following items:

Allocation of Inflow within the Perimeter of the Treatment Plant: Rain that falls within the perimeter of the treatment plant flows directly into the treatment facility as waste; henceforth, there is an associated cost of treatment. The City asked V&A to determine the volume of inflow that falls within the footprint of the treatment facility.

Treatment Plant Influent Meter: The City has two methods available to measure incoming flows from the City of Pinole. The City requested that V&A analyze the accuracy and determine which method is preferred for flow data reliability. This analysis was important for purposes of billing between the Cities of Pinole and Hercules. V&A dedicated a flow meter to measuring the flow into the treatment plant for comparison to the City meter; the results are presented within this deliverable as a Technical Memorandum.

These additional analyses are included in this report as Appendix A, Appendix B and Appendix C.

1.3 Flow Monitoring Basins
Flow monitoring basins are localized areas of a sanitary sewer collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances. The basin refers to the ground surface area near and enclosed by the pipelines. A basin may refer to the entire collection system upstream from a flow meter or may exclude separately monitored basins upstream.

To isolate a flow monitoring basin, an addition or subtraction of flows may be required3. Site M1 was not used as a basin because it served to measure the flow coming into the area of interest. Site M2 was not isolated as a basin because it would have required subtracting the flow from 11 other sites.

I/I analysis in this report will be conducted on a basin-by-basin basis. Table 1-4 lists the basins and sub-basins that were isolated4 and utilized for I/I analysis and Figure 1-4, Figure 1-5 and Figure 1-6 illustrate the basins utilized for I/I analysis.

3 There is error inherent in flow monitoring. Adding and subtracting flows increases error on an additive basis. For example, if Site A has error ±10% and Site B has error ±10%, then the resulting flow when subtracting Site A from Site B would be ±20%. 4 There may be locations with cross-connections between trunk sewers or overflow bypass sewers to help equalize basins and prevent sanitary sewer overflows during peak rain events.

2.0 METHODS AND PROCEDURES

2.1 Confined Space Entry
A confined space entry (Photo 2-1) is defined as any space large enough and so configured that a person can bodily enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy. In general, the atmosphere must be constantly monitored for sufficient levels of oxygen (19.5% to 23.5%), and the absence of hydrogen sulfide (H2S) gas, carbon monoxide (CO) gas, and lower explosive limit (LEL) levels. A typical confined space entry crew has members with U.S. Department of Labor, Occupational Safety & Health Administration-defined (OSHA-defined) responsibilities of "entrant,” "attendant,” and “supervisor.” The entrant is the individual performing the work. He or she is equipped with the appropriate level of personal protective equipment (PPE) needed to perform the job safely, including a personal four-gas monitor (Photo 2-2). If it is not possible to maintain line-of-sight with the entrant, then more entrants are required until line-of-sight can be maintained. The attendant is responsible for maintaining contact with the entrants to monitor the atmosphere using another four-gas monitor and maintaining records of all entrants. The supervisor is responsible for developing the safe work plan prior to entering.

2.2 Flow Meter Installation
A combination of Isco 2150 area-velocity meters and Hach Flo-Dar meters were installed by V&A in the sewer lines in Table 1-1, Table 1-2 and Table 1-3. Continuous depth and velocity readings were recorded by the flow meters on 5-minute intervals.

Isco 2150 meters use submerged sensors with a pressure transducer to collect depth readings and an ultrasonic Doppler sensor to determine the average fluid velocity. The ultrasonic sensor emits high-frequency sound waves, which are reflected by air bubbles and suspended particles in the flow.

The sensor receives the reflected signal and determines the Doppler frequency shift, which indicates the estimated average flow velocity. The sensor is typically mounted at a manhole inlet to take advantage of smoother upstream flow conditions. Figure 2-1 shows a typical installation for a flow meter with a submerged sensor.

Figure 2-1. Typical Installation for Flow Meter with Submerged Sensor The pipe diameter was verified in order to accurately calculate the flow cross-section. In-situ manual (hand) level and velocity measurements were taken and compared to simultaneous level and velocity readings from the flow meters to ensure proper calibration and accuracy. This determination of the level offset is required because of variations in individual flow meters, position of the sensor upon installation, thickness of the mounting band and other factors.

During the in-situ calibrations, the technician/engineer reports the actual depth of the flow to the invert of the pipe (dA) while the flow meter reports the depth of water to the sensor (ds). The difference between these is the offset. These sets of measurements are taken at least three times during installation and removal of the flow meters and during mid-project calibrations. The various sets of measurements are used to track the data quality. During site visits, observations of sediment City of Pinole
Sewer Flow Monitoring & inflow/Infiltration Study
V&A Project No. 13-0276 Methods and Procedures 20
are noted. If sediment is present, several depth of sediment readings (S) are taken and the type of sediment encountered (sandy, rocky, pebbly) is noted.

Most area-velocity meters employ a forward-looking ultrasonic Doppler sensor that does not record velocity if covered by sediment. To mitigate this, the sensor may be offset to a position where sediment is less likely to affect the sensor. It is important to take multiple sediment readings in multiple locations; sediment tends to settle in waves, which affects the accuracy of the sediment measurement if not accounted for.

Figure 2-2 illustrates a sensor offset for sediment, and the level measurements recorded during an in situ calibration. Figure 2-3 illustrates sediment wave pattern settlement commonly observed in sewer lines.

2.3 Flow Calculation
Data retrieved from each flow meter was placed into a spreadsheet program for analysis. Data analysis includes data comparison to field calibration measurements, as well as necessary geometric adjustments as required for sediment (sediment reduces the pipe’s wetted cross-sectional area available to carry flow). Area-velocity flow metering uses the continuity equation, ( ) Q v A v AT AS
where Q : volume flow rate
v: average velocity as determined by the ultrasonic sensor A: cross-sectional area available to carry flow

2.4 Average Dry Weather Flow Determination
Weekday and weekend flow patterns differ and must be separated when determining average dry weather flows. Days least affected by rainfall were used to estimate weekend and weekday average flows. The overall average dry weather flow (ADWF) was calculated per the following equation:

Figure 2-5 illustrates the varying flow patterns within a typical dry week.

Figure 2-5. Sample ADWF Diurnal Flow Patterns

2.5 Pipeline Capacity Analysis Methods
Peak measured flows and peak flow depths are important factors to consider when evaluating the capacity of the collection system. The peak flows and flow levels reported are from the peak measurements taken across the entirety of the flow monitoring period and may or may not correspond to a simultaneous event for all sites.

The following capacity analysis terms are defined as follows:

Peaking Factor: Peaking factor is defined as the peak measured flow divided by the ADWF. A peaking factor threshold value of 3.0 is commonly used for sanitary sewer design of new pipe; however, it is noted that this value is variable and subject to attenuation and the size of the upstream collector area. The City should follow its own standards and criteria when examining peaking factors.
d/D Ratio: The d/D ratio is the peak measured depth of flow (d) divided by the pipe diameter (D).
. The d/D ratio for each site was computed based on the maximum depth of flow for the flow monitoring study.

2.6 Inflow/Infiltration Analysis Methods
Inflow and infiltration (I/I) consists of stormwater and groundwater that enter the sewer system through pipe defects and improper storm drainage connections and is defined as follows.

2.6.1 Definition and Typical Sources
Inflow: Storm water inflow is defined as water discharged into the sewer system, including private sewer laterals, from direct connections such as downspouts, yard and area drains, holes in manhole covers, cross-connections with storm drains, or catch basins.

Infiltration: Infiltration is defined as water entering the sanitary sewer system through defects in pipes, pipe joints, and manhole walls, which may include cracks, offset joints, root intrusion points, and broken pipes.

Figure 2-6 illustrates the possible sources and components of I/I.

2.6.2 Infiltration Components
Infiltration can be further subdivided into the following components:

Rainfall-Dependent Infiltration: This component occurs as a result of storm water and enters the sewer system through pipe defects, as with GWI. The storm water first percolates directly into the soil and then migrates to an infiltration point. Typically, the time of concentration for rainfall-dependent infiltration (RDI) may be 24 hours or longer, but this depends on the soil permeability and saturation levels.

Groundwater Infiltration: Groundwater infiltration (GWI) depends on the depth of the groundwater table above the pipelines as well as the percentage of the system submerged.

The variation of groundwater levels and subsequent GWI rates are seasonal by nature. On a day-to-day basis, GWI rates are relatively steady and will not fluctuate greatly.

Rainfall-Responsive Infiltration is storm water that enters the collection system indirectly through pipe defects, but normally in sewers constructed close to the ground surface such as private laterals. Rainfall-responsive infiltration (RRI) is independent of the groundwater table and reaches defective sewers via the pipe trench in which the sewer is constructed, particularly if the pipe is placed in impermeable soil and bedded and backfilled with a granular material. In this case, the pipe trench serves as a conduit similar to a French drain, conveying storm drainage to defective joints and other openings in the system. This type of infiltration can have a quick response and graphically can look very similar to inflow.

2.6.3 Impact and Cost of Source Detection and Removal
Inflow:

Impact: This component of I/I creates a peak flow problem in the sewer system and may dictate the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows. Because the response and magnitude of inflow is tied closely to the intensity of the storm event, short-term peak flows may result in surcharging and overflows within a collection system. Severe inflow can result in sewage dilution, which may upset the biological process (secondary treatment) at the treatment facility.

Cost of Source Identification and Removal: Inflow locations are usually less difficult to find and less expensive to correct than infiltration sources. These sources include direct and indirect cross-connections with storm drainage systems, roof downspouts, and various types of surface drains. Generally, the costs to identify and remove sources of inflow are low compared to potential benefits to public health and safety or the costs of building new facilities to convey and treat the resulting peak flows.

Infiltration:

Impact: Infiltration typically creates long-term annual volumetric problems. The major impact is the cost of pumping and treating the additional volume of water, and of paying for treatment (for municipalities that are billed strictly on flow volume).

Cost of Source Detection and Removal: Infiltration sources are usually harder to find and more expensive to correct than inflow sources. Infiltration sources include defects in deteriorated sewer pipes or manholes that may be widespread throughout a sanitary sewer system.

2.6.4 Graphical Identification of Inflow and Infiltration Inflow is usually recognized graphically by large-magnitude, short-duration spikes immediately following a rain event. Infiltration is often recognized graphically by a gradual increase in flow after a wet-weather event. The increased flow typically sustains for a period after rainfall has stopped and then gradually drops off as soils become less saturated and as groundwater levels recede to normal levels. Real-time flows were plotted against average dry weather flow (ADWF) to analyze the I/I response to rainfall events. Figure 2-7 illustrates a sample of how this analysis is conducted and some of the measurements that are used to distinguish I/I. Similar graphs were generated for the individual flow monitoring sites and can be found in Appendix A.

Figure 2-7. Sample Infiltration and Inflow Isolation Graph

2.6.5 Analysis Methods
After differentiating I/I flows from ADWF flows, various calculations can be made to determine which I/I component (inflow or infiltration) is more prevalent at a particular site and to compare the relative magnitudes of the I/I components between drainage basins and between storm events. Inflow or infiltration components are typically normalized in up to three ways:
per-IDM: Inflow or infiltration rates are divided by length of pipe within the drainage basin, expressed in units of inch-diameter-mile (IDM) (miles of pipeline multiplied by the diameter of the pipeline in inches). Final units are gallons per day (gpd) per IDM. per-ACRE: Inflow or infiltration rates are divided by the acreage of the drainage basin. Final units are gallons per day (gpd) per ACRE.
per-ADWF: Inflow or infiltration rates are divided by the ADWF that was measured and established within the drainage basin. This is a ratio. The number is unitless, but can be thought of in the same light as a Peaking Factor.

City of Pinole
Sewer Flow Monitoring & inflow/Infiltration Study
V&A Project No. 13-0276 Methods and Procedures 27
The infiltration and inflow indicators were normalized by all three methods for this report per the following weighting system:

I/I Analysis
Method Weight
per-IDM 50%
per-ACRE 20%
per-ADWF 30%
The per-IDM method was given the highest weight because capital improvement projects concerning rehabilitation or replacement of sanitary sewer pipelines are most commonly bid based on the length of pipe. Note: inflow is subject to the effects of attenuation, explained in the following section.

2.7 Flow Attenuation
Flow attenuation in a sewer collection system is the natural process of the reduction of the peak flow rate through redistribution of the same volume of flow over a longer period of time. This occurs as a result of friction (resistance), internal storage and diffusion along the sewer pipes. Fluids are constantly working towards equilibrium. For example, a volume of fluid poured into a static vessel with no outside turbulence will eventually stabilize to a static state, with a smooth fluid surface without peaks and valleys. Attenuation within a sanitary sewer collection system is based upon this concept. A flow profile with a strong peak will tend to stabilize towards equilibrium, as shown in Figure 2-8.

Figure 2-8. Attenuation Illustration
Within a sanitary sewer collection system, each individual basin will have a specific flow profile. As the flows from the basins combine within the trunk sewer lines, the peaks from each basin will (a) not necessarily coincide at the same time, and (b) due to the length and time of travel through the trunk sewers, peak flows will attenuate prior to reaching the treatment facility. The sum of the peak flows of the individual basins within a collection system will usually be greater than the peak flows observed at the treatment facility.

3.0 RAINFALL RESULTS

3.1 Rainfall Data
There were sufficient rainfall events over the flow monitoring period that could be used to conduct multiple sets of infiltration and inflow analysis, allowing for relocation of flow meters and isolation of multiple drainage basins. V&A utilized rain data publically available through the National Weather Service (NWS) Cooperative Observer Program (COOP). While V&A performed QA/QC analysis to ensure, to the extent possible, the quality of the rainfall data, it is noted that V&A had no direct control over those gauges.

Table 3-1 shows the precipitation for the notable rainfall events measured from the four rain gauges.

Figure 3-1 illustrates the rain events over the monitoring period (average of all rain gauges shown).

Figure 3-2 shows the rainfall accumulation during the monitoring period, as well as the historical average rainfall5 in Pinole at the approximate study centroid during this project duration.

The cumulative precipitation at the four rain gauges ranged from 52% to 85% of the historical precipitation for the time period shown.

3.2 Regional Rainfall Event Classification
It is important to classify the relative size of a major storm event that occurs over the course of a flow-monitoring period6. Rainfall events are classified by intensity and duration. Based on historical data, frequency contour maps for storm events of given intensity and duration have been developed by the National Oceanic and Atmospheric Administration (NOAA) for Northern California (Figure 3-3).

Figure 3-3. NOAA Northern California Rainfall Frequency Map, Isopluvials of 10-year 24-hour precipitation in inches
For example, the NOAA Rainfall Frequency Atlas7 classifies a 10-year, 24-hour storm event at the PINOL5 rain gauge location as 3.75 inches. This means that in any given year, at this specific location, there is a 10% chance that 3.75 inches of rain will fall in any 24-hour period.

From the NOAA frequency maps, for a specific latitude and longitude, the rainfall densities for period durations ranging from 1 hour to 24 hours are known for rain events ranging from 1-year to 100-year intensities. These were plotted to develop a rain event frequency map specific to each rainfall monitoring site. Superimposing the peak-measured densities for the rainfall events on the rain event

6 Sanitary sewers are often designed to withstand I/I contribution to sanitary flows for specific-sized “design” storm events. 7 NOAA Western U.S. Precipitation Frequency Maps Atlas 14, 1973: http://www.wrcc.dri.edu/pcpnfreq.html City of Pinole

3.3 Rainfall Summary
Though the total rainfall for the entirety of the 2013/2014 rainfall season was generally low, Storm Event 1 provided sufficient rainfall to conduct a solid I/I analysis of the flow monitoring data gathered for Phase 1.

Event 1 was classified as greater than a 1-year, 24-hour event for some rain gauges in the region. Event 1 also increased the soil saturation levels so that future rainfall events (Events 2 and 3) were effective for I/I analysis of the flow monitoring data collected for Phase 2 and Phase 3.

4.2 Peak Measured Flows and Pipeline Capacity Analysis
Capacity analysis data is presented on a site-by-site basis and represents the hydraulic conditions only at the point site locations. Hydraulic conditions in other areas of the collection system will differ.

Due to the relocation of flow meters and different flow data capture periods, the peak flows and peak levels should not necessarily be directly compared to each other. The period of meter installation are coded per the following scheme:

Scheme Install Period
A 1/17/2014 – 2/25/2014
B 1/17/2014 – 3/28/2014
C 1/17/2014 – 4/1/2014
D 2/25/2014 – 3/28/2014
E 2/25/2014 – 4/1/2014
F 3/28/2014 – 4/1/2014
Table 4-2 summarizes the peak recorded flows, levels, d/D ratios, and peaking factors per site during the flow monitoring period. Sites that surcharged and sites with peaking factors greater than

10.0 have been shaded in RED. Figure 4-4, Figure 4-5 and Figure 4-6 show bar graphs of the capacity results for all phases. Figure 4-7, Figure 4-8 and Figure 4-9 show schematic diagrams of the peak measured flows with peak flow levels for all phases of the flow monitoring.

The following capacity analysis results are noted:

Peaking Factor: Several sites had peaking factors greater than 10. Larger peaking factors are expected given that the study analyzes basins previously identified as having I/I rates. d/D Ratio: Nine of the flow monitoring sites (Sites M2, M5, M6, M10, M11, M12, M14, M16 and M6.1) reached surcharge conditions.

These capacity results do not replace a full hydraulic model which would determine capacity on a node-to-node basis and would be based on pipe slopes of the individual pipe segments within the local collection system.

5.0 PHASE 1 I/I RESULTS

5.1 Preface
The original 16 flow monitoring basins were illustrated in Figure 1-4. The following items are noted regarding the early-season analysis:

Results are presented on a basin-by-basin basis (not a site-by-site basis).

Results are for the original 15 basins only (Basin 12 excluded).

Results presented to the City during the early-season were considered preliminary and based upon the information known at the time of presentation.

Results presented in the following pages of analyses have been updated from the initial presentation to reflect final data and results; values may be different from the initial presentation; however, the conclusions and recommendations are the same.

5.2 Inflow Analysis
Inflow sources transport rain water directly into the sewer system; the corresponding inflow rates are tied closely to the intensity of the storm. This component of RDI/I often causes a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows.

Figure 5-1 illustrates the I/I response curve for Basin 3 and Storm Event 1 as it relates to peak I/I rate.

5.3 Combined I/I Analysis
Combined I/I analysis considers the totalized volume (in gallons) of both inflow and rainfalldependent infiltration over the course of a storm event. For example, the total volume of infiltration and inflow into Basin 3 for the February 7 - 12, 2014 storm event calculated out to 670,000 gallons (hatched area below in Figure 5-3).

5.4 Phase 1 Summary
On February 20, 2014, V&A met with the City to discuss the Phase 1 findings. At the time of the discussion, peak I/I to ADWF ratios and total combined I/I contribution were main topics of discussion, presented in the format of I/I response curves per each monitoring site (similar to Figure 5-1). The following bullet items highlight important topics of discussion between V&A and the City:

Basin 3: The City cited historical data and field observations regarding known I/I issues within Basin 3.

Basin 5: V&A recommended investigating Basin 5 due to the high peak I/I ratios and high combined I/I totals.

Basin 6: There is a known capacity issue one manhole upstream from the Basin 6 monitoring location.

Basin 8: This is a newer area of the City and this area had minimal I/I contribution.

Basin 11: This location had significant peak I/I rates and combined I/I totals.

City of Pinole
Sewer Flow Monitoring & inflow/Infiltration Study
V&A Project No. 13-0276 Phase 1 I/I Results 49
Basin 12: The metering manhole for this basin surcharged with evidence that the surcharge was close to an SSO.

Basins 15/16: Both basins were noted for generally high I/I rates and total I/I contribution.

Old Henry Road: The City cited the age of the sewer system along Old Henry Road and noted this correlation to the high I/I rates within Basins 9, 11 and 12.

5.4.1 Conclusions
Final group conclusions were as follows:

Focus the Phase 2 monitoring within Basins 3, 5 and 6.

The focus of the study moving forward would be to spend the remainder of the 2014 wet weather season identifying smaller high I/I mini-basins within this region for possible future CIP work.

Make note of the ‘Old Henry Road’ Basins as future candidates for a focused flow monitoring and I/I study.

5.4.2 Actions
Future actions for Phase 2 included the following:

Remove ten flow meters from the following sites: M1, M5, M8 – M16.

Utilize the ten available flow meters to further analyze and gather data on the high I/I basins as follows:

Basin 3: Sub-divide into two basins (3.1 and 3.2) and perform Phase 2 flow monitoring.

Basin 5: Sub-divide into three basins (5.1, 5.2 and 5.3) and perform Phase 2 flow monitoring.

Basin 6: Sub-divide into five basins (6.1, 6.2, 6.3, 6.4 and 6.5) and perform Phase 2 flow monitoring.

6.0 PHASE 2 I/I RESULTS

6.1 Preface
The Phase 2 flow monitoring occurred from February 26, 2014 through March 6, 2014. The ten flow monitoring sub-basins designated for the Phase 2 analysis are illustrated in Figure 1-5. The following items are noted regarding the early-season analysis:

Results are presented on a basin-by-basin basis (not a site-by-site basis).

Results are for the ten Phase 2 basins only.

Results presented to the City during Phase 2 were considered preliminary and based upon the information known at the time of presentation.

Results presented in the following pages of analyses have been updated from initial presentation to reflect final data and results. The values presented in this report will differ from the initial presentation; however, the conclusions and recommendations are the same.

6.2 I/I Summary of Results

6.3 Phase 2 Summary
On March 18, 2014, V&A met with the City to discuss the Phase 2 findings. At the time of the discussion, the measured peak I/I rates were the main topics of discussion, presented in the format of I/I response curves per each monitoring site. The following bullet items highlight important topics of discussion between V&A and the City:

Basin 3.1/Basin 3.2: Basin 3.1 had significantly more peak I/I than Basin 3.2. Basin 3.1 had

0.55 mgd of peak I/I flow occurring within only approximately 2,700 lineal feet of pipe.

Rehabilitating the 2,700 lineal feet of pipe is a realistic CIP project that can have significant impact at the treatment plant. For Storm Event 2, at the treatment plant, there was approximately 2.47 mgd of peak I/I. Though not a perfect comparison due to attenuation and holding times within the collection system, 0.55 mgd peak inflow from Basin 3.1 is approximately 22% of the 2.47 mgd peak inflow measured from the City of Pinole for Storm Event 2.

Basin 5.2 and Basin 6.5 also had high peak I/I rates.

The City was interested in obtaining the percentage volume of flow contribution at the intersection of Roble Avenue and Appian Way where two main sewers combine.

Basin 6.3: The City was interested in directly monitoring flows in the numbered streets if possible (2nd Avenue to 5th Avenue).

6.3.1 Recommendations
Final group recommendations were as follows:

Focus the Phase 3 monitoring within Basins 3.1, 5.2 and 6.5 for focused I/I analysis.

Monitor the Roble/Appian junction and capture the sewerage basins for Third Avenue and 5th Avenue.

6.3.2 Actions
Remove seven flow meters from the following sites: M3.2, M5.1, M6.1, M6.2, M6.4, M7 and M13.

Utilize the seven available flow meters plus one extra meter to further analyze and gather data on the high I/I basins as follows:

Basin 3.1: Sub-divide into three basins (3.1, 3.1A, 3.1B) for Phase 3 flow monitoring.

Basin 5.2: Sub-divide into three basins (5.2, 5.2A and 5-3) for Phase 3 flow monitoring.

Basin 6.3: Sub-divide into three basins (6.3, 6.3A and 6.3B) for Phase 3 flow monitoring.

Basin 6.5: Sub-divide into three basins (6.5, 6.5A and 6.5B) for Phase 3 flow monitoring.

7.3 Phase 3 Summary
On April 15, 2014, V&A met with the City to discuss the Phase 3 findings. The following bullet items highlight important topics of discussion between V&A and the City:

Basin 3.1: Basin 3.1 had previously been broken into three parts in order to refine the potential location for the high rates of inflow.

The high rates of inflow were once more confirmed in Basin 3.1. Basin 3.1 had the highest rate of inflow amongst the three Basin 3.1 meters (3.1, 3.1A and 3.1B) Basin 5.2: Previously, Basin 5.2 had very high rates of inflow for a relatively small service area. This basin was divided approximately in half to further refine the problem area.

Of the two sub-basins (5.2 and 5.2A), Basin 5.2 had the vast majority of I/I.

Basin 6.5: During Phase 2, Basin 6.5 was one of the two highest ranked basins. This was divided into three sub-basins (6.5, 6.5A and 6.5B).

Basin 6.5 had the highest rate of inflow
Basin 6.3A: The rate of inflow observed in Basin 6.3A was higher than expected.

V&A Project No. 13-0276 Recommendations 56

8.0 RECOMMENDATIONS
V&A advises that future I/I reduction plans consider the following recommendations:

3. Other I/I Investigation Methods: Potential other I/I investigation methods include the following:
a. Smoke testing
b. Night-time reconnaissance work to (1) investigate and determine direct point sources of inflow, and (2) determine the areas and pipe reaches responsible for high levels of infiltration contribution.

A.1 Flow Split between M6.0A and M6
As a part of Phase 3, the City asked that the flow split between Sites M6.0A and M6.3 be monitored.

Site M6.0A monitored a 10-inch line running southwest along Pinon Ave that gathers flow from Basin 5 (Phase 1) as well as the area near the intersection of Appian Way and San Pablo Ave. Site M6.3 monitors an 8-inch line that gathers flow from Basin 3, Basin 6.5, Basin 6.4 and Basin 6.3. The flows from these two sites eventually travel through Site M6.

The average and peak flow splits for the two sites are illustrated in Figure A-1 and Figure A-2.

Figure A-1. ADWF Split for Site M6.3 and
M6.0A
Figure A-2. Peak Flow Split for Site M6.3

The split in flows between the two lines was approximately 40% for Site M6.0A and 60% for Site M6.3 for Average Dry Weather Flow.

The split in flows between the two lines was approximately 52% for Site M6.0A and 48% for Site M6.3 for Peak Flow during Storm Event 3.

B.1 Treatment Plant Inflow Contribution
The City of Pinole shares ownership of the Wastewater Treatment Plant with the City of Hercules.

One aspect that is currently not addressed between the cities is the cost of treating the rainfall that falls on the footprint of the treatment plant itself.

The footprint of the treatment plant (Figure B-3) is approximately 228,300 ft2 (5.28 acres). This equates to 142,300 gallons per inch of rain that falls. The City of Pinole averages approximately

20.25 inches of rain per year. With the drainage on the treatment plant property, the majority of this rainfall would flow into the treatment process. In total, this results in approximately 2,880,000 gallons of rainfall that is treated by the treatment facility each year.

1.0 INTRODUCTION
The Pinole/Hercules Wastewater Treatment Plant treats sanitary sewage flow from both the City of Pinole and the City of Hercules. Presently, the Hercules flows are measured directly through a Parshall flume located at the treatment plant. Pinole flows are measured using two methods:

Method 1: Indirect measurement by subtracting the Hercules flows from the totalized treatment plant effluent flows, monitored at an effluent weir structure. This method has traditionally been the primary method for determining flows from the City of Pinole.

Method 2: Direct measurement using a Hach FloDar flow meter located on the 30-inch line on Tennant Avenue as it enters into the treatment facility. This 30-inch line captures the entirety of the sanitary sewer waste from the City of Pinole collection system.

V&A Consulting Engineers (V&A) was retained by the City of Pinole (City) to compare both methods of flow calculation to temporary flow monitoring conducted on the 30-inch line on Tennent Avenue, just east of the railroad tracks, approximately 240 feet upstream from the City Influent Meter. The 30- inch line captures the entirety of the sanitary sewer waste from the City of Pinole collection system.

Flows from the Influent, Hercules and Effluent meters were provided by the City. V&A was provided two different types of data sets from the influent (FloDar) meter:

Data Set 1: The City provided 15-minute interval data for the Influent flow meter from November 1 through December 10, 2014.

Data Set 2: V&A accessed the flow meter directly and was able to retrieve five days of 1- minute interval data from January 18 to 23, 2015.

These data sets were analyzed separately and for different purposes that will be outlined later in this report.

V&A was initially retained by the City to perform sanitary sewer flow monitoring during the 2013/2014 wet weather season as part of the City’s efforts to reduce inflow and infiltration (I/I) within the City collection system. Through the 2014 summer months, V&A maintained the flow meter that was already installed on Tennent Avenue. This work was performed under the same contract as the 2013/2014 Flow Monitoring and I/I Analysis work.

Figure 1-1 illustrates a map of the treatment plant and the Pinole and Hercules trunk sewer lines.

2.1 Review of Validity of City Data for Analysis
The City provided 15-minute interval data for the Hercules Parshall flume and for the treatment plant effluent from June 14, 2014 to September 25, 2014. V&A performed a cursory QA/QC on the data provided. The data from June 14 through July 20, 2014 appeared to have been reported correctly and is considered as valid data sets for comparison. From July 21, 2014 forward, there were only a few valid data points for each data set per day, resulting in several “flat-lines” or repeated values in the data sets, illustrated in Figure 2-1.

Figure 2-1. Hercules and Effluent Flow Data, 7/17/2014 – 7/27/2014 For Method 1 Flows, the data from July 21 forward was not considered valid for comparison for the purposes of this study.

2.2 Micro Analysis
V&A first looked at the data at the 15-minute data interval level. Though the City does not report totalized flows at this interval level; however, analyzing the data on a micro level may lend confidence or provide valuable information as to the operational viability of the metering methods currently in use. Figure 2-2 shows a graph of the flow monitoring data sets evaluated for this study.

The purple line labeled “Pinole+Hercules” is simply a sum of the directly monitored values for Pinole and Hercules and is intended to be shown as a direct comparison to the Effluent data.

Figure 2-2. Hercules and Effluent Flow Data, 6/23/2014 – 6/30/2014 It is noted that the Effluent flows undergo some degree of attenuation; there is detention time in between the influent and effluent stages of the treatment process. The following items are noted:
analysis:

The Effluent flow data and the sum of the directly monitored data sets (“Pinole + Hercules”) match each other well in terms of magnitude and range.

When operating correctly, the diurnal curves and trends of the flow data from the Hercules Parshall flume and the Effluent Weir appear to provide solid and repeatable data.

2.3 Macro Analysis
Flow data was analyzed on a day-by-day basis to determine the estimated difference in the calculated flow for Pinole (present method -- Effluent less Hercules) versus the measured flows per the V&A flow monitoring conducted on the 30-inch trunk sewer on Tennent Avenue. Table 2-1 shows the daily flow comparison of the daily calculated flows versus the measured City flows.

Method 1 Flow Measurement Summary
Using the Method 1 determination of the City of Pinole flows, the flows for Pinole are over-reported by approximately 15.2%.

Note: V&A has no knowledge of the accuracy of the flow data from Hercules and the plant. It is also noted that the industry standard for open-channel flow monitoring is expected to have an accuracy of approximately ±5%.

V&A Project No.: 13-0276 Method 2, Data Set 1 6

3.0 METHOD 2, DATA SET 1

3.1 Review of Validity of City Data for Analysis
Similar to the data sets provided for the Hercules and Effluent flows of the previous section, the data set had many repeated values and flat-lines, illustrated in Figure 3-1.

Figure 3-1. Pinole Influent Data, 11/10/2014 – 11/17/2014 Given that the repeated values occurred with all data sets, and occurred for the same date/time stamps for concurrent data sets of different meters, it is believed the repeated values are not an indication of meter failure, but an indication of data storage error within the City SCADA system.

For the purposes of the Method 2, Data Set 1 analysis, V&A assumed that non-repeated data points were valid at the time of the date/time stamp, but that repeated values were not valid data points.

Figure 3-2 illustrates an example of valid data points for analysis and direct comparison to the V&A temporary flow meter.

4.0 METHOD 2, DATA SET 2
Data Set 2 was 1-minute interval data accessed directly from the flow meter and thus did not have the “repeated-value” issue noted in previous sections. This data set was utilized to better analyze the sensor measurements of the FloDar flow meter and perhaps lend information to understand why the values in Data Set 1 were over-reported.

Velocity Outliers
There are several velocity point outliers that, based on the hydraulic conditions at the treatment plant, are known to be incorrect and over-reported. This is not an uncommon occurrence with flow monitoring equipment. The FloDar meter measures surface velocity of the flow stream; excessive floating debris or bubbles or foam on the flow surface could cause this issue.

For this data set, V&A went through the exercise of correcting the velocity values to determine the overall effect of these outliers on the flow data. Figure 4-2 illustrates the corrected velocity measurements.

The flow calculation programmed into the FloDar meter did not consider the volume of sediment within the pipe channel. The cross-sectional area filled with sediment is not available for conveyance of waste stream flow. It is known that this particular trunk sewer has a sediment issue. Assuming no sediment would result in the over-reporting of flow values.

The exact level of sediment at the Influent Meter location was not known. The sediment at the V&A Meter approximately 240 feet upstream from the Influent Meter manhole measured approximately 2 inches. For Data Set 2, assuming 2 inches of sediment in the pipe channel would result in a 5.7% reduction of flow.

Data Set 2 Analysis Summary
If the velocity outliers were corrected and 2 inches of sediment was accounted for in the pipeline, the overall impact on the flows reported by the FloDar would be approximately 14.8%. This number corresponds well with the percentage difference in flows analyzed in Data Set 1 (13.9%).

5.0 DISCUSSION
The following discussion items are presented for review by the City:

Primary Devices vs. Flow Meters: Primary devices, flumes and weirs, traditionally have been a popular and reliable method to measure flows in permanent installations. The main limitations of these methods is that there are constraints on where such devices can be installed and once installed, moving them to a different location is difficult. Primary devices are less reliant on technology because one of the parameters used to calculate flow is removed from the equation as a variable.

Method 1 (Effluent less Hercules): Using the Method 1 determination of the City of Pinole flows, the flows for Pinole are over-reported by approximately 15.2%.

The flow monitoring methods used presently to determine the Hercules flows and the Effluent flows appear to be repeatable.

Method 2 (Influent meter direct measurement): The influent meter was over-reporting flows by approximately 13.9% per comparison of valid data points within Data Set 1 and the V&A temporary meter.

Detailed analysis of the 1-minute level and velocity data reported from the FloDar meter indicates that there are likely two causes for this over-reporting:

Cause #1: There are velocity outliers reported by the FloDar that cause the velocity to be over-reported. For the five days of data analyzed, these outliers caused the flows to be over-reported by 9.1%.

Cause #2: There are known sediment issues in the pipeline where the influent meter is located. The FloDar meter was not programmed to account for sediment when calculating flow. The exact level of sediment in that manhole was not known at the time of this report. If one assumes 2 inches of sediment as measured 240 feet upstream from the influent meter, then the net effect of accounting for the sediment would be a reduction of flow of approximately 5.7% (Data Set 2).

Preferred Method: Given the known sediment issues at the influent meter location, and also given the repeatability and sustainability of the Primary Device used at the Effluent Meter location, Method 1 would be considered the preferred method for determining the City of Pinole flows generated from the collection system on a mass flow basis.

Note: Instantaneous flows from the City of Pinole cannot be determined due to attenuation and hold times through the treatment process.

CIP DETAIL SHEETS

CITY COUNCIL
REPORT 12A
DATE: SEPTEMBER 20, 2022
TO: MAYOR AND COUNCIL MEMBERS
FROM: SANJAY MISHRA, PUBLIC WORKS DIRECTOR
SUBJECT: OVERVIEW OF CITY-WIDE PROJECT LABOR AGREEMENTS

RECOMMENDATION
Staff recommends that the City Council receive information on project labor agreements (PLA) and provide direction, if any, on next steps.

BACKGROUND
The City Council requested that City staff provide information on PLAs.

A PLA is defined as a pre-hire collective bargaining agreement between a construction project sponsor/owner and one or more labor organizations that establishes terms and conditions of employment for a specific construction project or projects. PLAs are also sometimes referred to as Community Workforce Agreements. PLA’s typically address challenges commonly associated with complex construction projects, such as avoiding labor disruptions, while providing specific benefits by setting participation goals for local businesses.

PLAs are described in Title 29, Section 158(f) of the United States Code. Public Contract Code 2500(a) enables cities to utilize PLAs.

PLAs must have specific taxpayer protection provisions, including the following:

1. The agreement prohibits discrimination based on race, national origin, religion, sex, sexual orientation, political affiliation, or membership in a labor organization in hiring and dispatching workers for the project.

2. The agreement permits all qualified contractors and subcontractors to bid for and be awarded work on the project without regard to whether they are otherwise parties to collective bargaining agreements.

3. The agreement contains an agreed-upon protocol concerning drug testing for workers who will be employed on the project.

4. The agreement contains guarantees against work stoppages, strikes, lockouts, and similar disruptions of the project.

City Council Report, 12A
March 1, 2022 2

5. The agreement provides that a neutral arbitrator shall resolve disputes arising from the agreement.

REVIEW & ANALYSIS
The City of Pinole has entered PLAs on individual City construction projects in the past.

For example, the City entered into a PLA when it performed the Water Pollution Control Plant Upgrade (See Attachment A).

Several agencies, including the County and cities such as Hayward, Martinez, Sacramento, San Francisco, San Jose, and Watsonville have utilized PLAs on individual projects. As a result of their successful experience with PLAs, they have adopted policies that require that they use PLAs on public construction projects that meet certain criteria and have established overarching PLAs with the relevant labor organizations in their jurisdictions. The overarching PLA establishes terms and conditions on projects within the city that meet specific pre-agreed upon requirements and thresholds PLAs usually address wage irregularities and ensures a minimum level of local business participation in the public contracts. Local business participation requirements help local construction labors, trucking, suppliers etc. PLAs seems to benefit local economy, promotes local hires and offers project stability related to labor disputes. A criticism of PLAs is that they increase the cost of construction by requiring payment of union wages to non-union workers. All public contract projects are required to pay prevailing wages (per the public contract code) and comparable to the union wages.

Most of the PLA agreements reviewed by staff had similar language but differed on the project thresholds, local hiring goals, and inclusion of a disadvantaged resident program. • Project Thresholds
The application of the policy in several of the PLAs reviewed was determined by a construction project's minimum bid amount (the "Threshold"). For example, after forming an Ad Hoc Committee and discussing the item with key staff members, the City of Martinez adopted a policy with a threshold of $500,000. The City of Watsonville has determined its threshold to be on all competitively bid public works construction projects with a projected construction cost of $600,000. The City of Hayward’s Community Workforce Agreement covers all construction projects with a minimum cost of $1,000,000.
• Local Hiring Goals
Several cities found that the construction jobs that are created by City-funded projects can be used to facilitate their local hire goals (i.e., hiring from a socio-economic group, within a certain geographic boundary, certain income boundary etc.). The City of City Council Report, 12A
March 1, 2022 3
Watsonville determined that project labor agreements have proven to be a valuable vehicle for accomplishing their local hire goals, and their City-Wide PLA policy was written to include any local hire ordinance adopted by the City of Watsonville. The CityWide PLA agreement entered into by the City of Hayward included a goal that Hayward residents perform a minimum of thirty (30%) of the hours worked on a craft-by-craft basis.
• Inclusion of a Disadvantaged Resident Program
The City of Hayward’s City-Wide PLA recognized a desire to facilitate the entry of veterans who are interested in careers in the building and construction industry and agreed to utilize the services of the Center for Military Recruitment, Assessment and Veteran’s Employment Center and the “Helmets to Hardhats” program to serve as a resource for employment opportunities and training to the extent permitted by law. The City of Watsonville’s PLA also requires the use of the “Helmets to Hardhats” program to assist returning veterans in obtaining employment and training opportunities on public works construction projects.

Cities often take the following steps to determine what an overarching PLA should contain:

1. formation of ad-hoc council subcommittee to study the item in further detail;

2. presentations and study sessions to the City Council;

3. meetings between senior staff members of the city and local union groups where specific terms were negotiated; and

4. preparation of a draft PLA for the Council to consider at a publicly held City Council meeting.

City staff is seeking Council direction on whether to take next steps on the issue of PLAs.

FISCAL IMPACT
There is no fiscal impact in receiving and accepting this report. This is for information and discussion by Council for direction to staff.

RECITALS
WHEREAS, the Pinole-Hercules Wastewater Treatment Plant is an estimated $48 million public works project that will replace the existing Pinole-Hercules Water Pollution Control Plant (WCPC) with a state-of-the-art wastewater treatment facility; and WHEREAS, the successful completion of the Pinole-Hercules Wastewater Treatment Plant is of the utmost importance to the general public in the Cities of Pinole and Hercules because the project is needed to provide additional wastewater treatment capacity in order to accommodate the cities’ growth and in order to bring treatment operations into compliance with standards set forth by the State Water Resources Control Board; and
WHEREAS, the proposed Pinole-Hercules Wastewater Treatment Plant will provide the region with a modern facility that will be able to process twice as much wastewater as the current plant and do so in a more environmentally sound manner; and
WHEREAS, the Pinole-Hercules Wastewater Treatment Plant will replace the current facility and bring the plant’s operations into compliance with the Regional Water Quality Control Board’s permit requirement and other applicable state and federal regulations; and
WHEREAS, construction of the plant is expected to begin in January 2016 and take approximately 30 months to complete; and
WHEREAS, the timely and successful completion of the Pinole-Hercules Wastewater Treatment Plant is necessary in order to avoid potential fines by the State Water Resources Control Board if the Project is not completed by September 30, 2017 when the current operating permit expires; and
1 WHEREAS, the new Pinole-Hercules Wastewater Treatment Plant will be located on the same site as the existing treatment facility, which will continue operations during the project; and
WHEREAS, City workers will continue to be responsible for treatment operations, including, but not limited to routine maintenance and repairs, which will not be covered by the Project Labor Agreement; and
WHEREAS, performing construction in an operational plant presents logistical challenges for the City employees, Unions and Contractors; and WHEREAS, the parties agree that one of the primary purposes of this agreement is to avoid the tensions that may arise on the Project because Union and nonunion workers may be required to work side by side on the Project, thereby leading to labor disputes that could delay completion of the Project; and WHEREAS, any work disruptions on this Project could pose significant risk to public health and safety and potentially expose the City to fines; and WHEREAS, workers of various skills will be required in the performance of the construction work, including those to be represented by the Unions signatory to this Agreement and employed by contractors and subcontractors who are signatory to this Agreement; and
WHEREAS, it is recognized that on a Project of this magnitude with multiple contractors and bargaining units on the job site at the same time over an extended period of time, the potential for work disruption is substantial without an overriding commitment to maintain continuity of work; and
WHEREAS, the interests of the general public, the City, the Unions and the Contractor would be best served if the construction work proceeds in an orderly manner without disruption because of strikes, sympathy strikes, work stoppages, picketing, lockouts, slowdowns or other interferences with work; and 2 WHEREAS, the Contractors and the Unions desire to mutually establish and stabilize wages, hours and working conditions for the workers employed on the Project by the Contractors and that a satisfactory, continuous and harmonious relationship will exist among the parties to this Agreement; and
WHEREAS, this Agreement is not intended to replace, interfere with, abrogate, diminish or modify existing local or national collective bargaining agreements in effect during the duration of the Project, insofar as a legally binding agreement exists between the Contractor/Employer(s) and the affected Union(s), except to the extent that the provisions of this Agreement are inconsistent with said collective bargaining agreements, in which event, the provisions of this Agreement shall prevail; and WHEREAS, contracts for the Project will be awarded in accordance with the applicable provisions of local, state and federal laws, including State Public Contract Code and Davis-Bacon and State Prevailing Wage Requirements, state and federal regulations, as well as the terms of the financing agreement with the State Water Board’s Clean Water State Revolving Fund; and
WHEREAS, the City has the absolute right to select the lowest responsive and responsible bidder for the award of construction contracts on the Project; and WHEREAS, the City places high priority upon the development of comprehensive programs for the recruitment, training and employment of local area residents, and recognizes the potential of local apprenticeship programs to provide meaningful and sustainable careers in the building and construction industry; and WHEREAS, the parties signatory to this Agreement pledge their full good faith and trust to work towards mutually satisfactory completion of the Project;

5.3 At the time that any Contractor enters into a subcontract with any subcontractor providing for the performance of work under a Construction Contract, the Contractor shall provide a copy of this Agreement to said subcontractor and shall require the subcontractor as a precondition of accepting an award of a construction subcontract to agree in writing, by executing the Agreement To Be Bound (Addendum A), to be bound by each and every provision of this Agreement prior to the commencement of work. The obligations of a contractor may not be evaded by subcontracting.

5.4 This Agreement shall only be binding on the parties signatory to this Agreement or to an Agreement To Be Bound, as well as to their successors and assigns, and shall not apply to the parents, affiliates, subsidiaries, or other ventures of any such party. Each Contractor shall alone be liable and responsible for its own individual acts and conduct and for any breach or alleged breach of this 11 Agreement.

ARTICLE 6

WORK STOPPAGES, STRIKES, SYMPATHY STRIKES AND LOCKOUTS

6.1 The Unions, City and Contractors agree that for the duration of the Project:
12 (a) There shall be no strikes, sympathy strikes, work stoppages, picketing, handbilling or otherwise advising the public that a labor dispute exists, or slowdowns of any kind, for any reason, by the Unions or employees employed on the Project, at the job site of the Project or at any other facility of the City or Contractors because of a dispute on the Project. Nor shall the Unions or any employees employed on the Project participate in any strikes, sympathy strikes, work stoppages, picketing, hand billing, slowdowns, or otherwise advising the public that a labor dispute exists at the jobsite of the Project because of a dispute between Unions and Contractor on any other project. Withholding employees, but not picketing, for failure of a Contractor(s) to tender trust fund contributions as required in accordance with Article 11 and/or for failure to meet its weekly payroll is not a violation of this Article; however, the Union shall give the affected Contractor, Project Manager and the City written notice no less than five (5) working days prior to the withholding of employees. Should a Contractor performing work on this Project be delinquent in the payment of Trust Fund contributions required under this Agreement with respect to employees represented by the Union, the Union may request that the General Contractor issue joint checks payable to the Contractor and the appropriate employee benefit Trust Fund(s) until such delinquencies are satisfied. Any Trust Fund claiming that a Contractor is delinquent in its fringe benefit contributions to the funds will provide written notice of the alleged delinquency to the affected Contractor, with copies to the General Contractor, Project Manager, and City. The notice will indicate the amount of delinquency asserted and the period that the delinquency covers. It is agreed, however, with respect to contractors delinquent in trust or benefit 13 contribution payments, that nothing in this Agreement shall affect normal contract remedies available under the local collective bargaining agreements and or Trust Agreements. Nothing stated in this Agreement shall prevent Unions from participating in the actions mentioned in this section on jobsites other than the Project jobsite because of disputes between the Unions and Contractors on projects other than this Project. (b) There shall be no lockout of any kind of any employee employed on the Project by a Contactor covered by the Agreement.
(c) If a Master Agreement expires during the term of this Agreement, it is specifically agreed that there shall be no strike, sympathy strike, work stoppage, picketing, hand billing or otherwise advising the public that a labor dispute exists, or a slowdown of any kind. The wages, benefits, and terms of employment established and set under the initial Master Agreement shall continue in full force until the completion of the Project. (d) Notification: If the City, Project Manager or Contractor contends that any Union has violated this Article, it shall notify by phone, email, and overnight mail the Senior Executive of the Council and the Senior Executive of the Union, setting forth the facts alleged to violate the Article, prior to instituting the expedited arbitration procedure set forth below. The Senior Executive of the Council will immediately use his/her best efforts to cause the cessation of any violation of this Article. The leadership of the Union will direct the membership to cease any violation of this Article. A Union complying with this obligation shall not be liable for unauthorized acts of employees it represents.
14 6.2 Expedited Arbitration: Any party to this Agreement shall institute the following procedure, prior to initiating any other action at law or equity, when a breach of this Article is alleged to have occurred:
(a) A party invoking this procedure shall notify Robert Hirsch, as the permanent arbitrator, or, Barry Winograd, as the alternate under this procedure. In the event that the permanent arbitrator is unavailable at any time, the alternate will be contacted. If neither is available, then a selection shall be made from the list of arbitrators in Article 14.2. Notice to the arbitrator shall be by the most expeditious means available, with notices by phone, email, and overnight mail to the party alleged to be in violation and to the Council and involved local Union if a Union is alleged to be in violation.
(b) Upon receipt of said notice, the City will contact the designated arbitrator named above or his alternate who will attempt to convene a hearing within twenty-four (24) hours if it is contended that the violation still exists. (c) The arbitrator shall notify the parties by phone, email, and overnight mail of the place and time for the hearing. Said hearing shall be completed in one session, which, with appropriate recesses at the arbitrator’s discretion, shall not exceed twenty-four (24) hours unless otherwise agreed upon by all parties. A failure of any party to attend said hearings shall not delay the hearing of evidence or the issuance of any award by the arbitrator.
(d) The sole issue at the hearing shall be whether or not a violation of Article 6 of the Agreement has occurred. The arbitrator shall have no authority to consider any matter of justification, explanation or mitigation of such violation or to award damages, which issue is reserved for court 15 proceedings, if any. The award shall be issued in writing within three (3) hours after the close of the hearing, and may be issued without a written opinion. If any party desires a written opinion, one shall be issued within fifteen (15) days, but its issuance shall not delay compliance with or enforcement of the award. The arbitrator may order cessation of the violation of this Article and other appropriate relief and such award shall be served on all parties by hand or registered mail upon issuance. Should a party found in violation of this Article fail to comply with an Arbitrator’s award to cease the violation, the party in violation shall pay to the affected party as liquidated damages the sum of ten thousand dollars ($10,000.00) per shift for which it failed to comply, or portion thereof, until such violation is ceased. The Arbitrator shall retain jurisdiction to resolve any disputes regarding the liquidated damages claimed under this section. (e) Such award may be enforced by any Court of competent jurisdiction upon the filing of this Agreement and all other relevant documents referred to above in the following manner. Written notice of the filing of such enforcement proceedings shall be given to the other party. In the proceeding to obtain a temporary order enforcing the arbitrator’s award as issued under Section 6.2(d) of this Article, all parties waive the right to a hearing and agree that such proceedings may be ex parte. Such agreement does not waive any party’s right to participate in a hearing for a final order or enforcement. The Court’s order or orders enforcing the arbitrator’s award shall be served on all parties by hand or delivered by certified mail.
16 (f) Any rights created by statute or law governing arbitration proceedings inconsistent with the above procedure, or which interfere with compliance, are waived by the parties.
(g) The fees and expenses of the arbitrator shall be divided equally between the party instituting the arbitration proceedings provided in this Article and the party alleged to be in breach of its obligation under this Article. (h) Should either the permanent or the alternate arbitrator listed above no longer work as a labor arbitrator, the City and the Council shall mutually agree to a replacement.

13.2 No grievance shall be recognized unless the grieving party (Local Union on its own behalf, or on behalf of an employee whom it represents, the City, or a Contractor) provides notice in writing to the party with whom it has a dispute within five (5) business days after becoming aware of the dispute but in no event more than thirty (30) business days after it reasonably should have become aware of the event giving rise to the dispute. Time limits may be extended by mutual written agreement of the parties.

Step 1: Within five (5) business days after the receipt of the written notice of the grievance, the Business Representative of the involved Local Union 23 or District Council, or his/her designee, or the representative of the employee, and the representative of the involved Contractor shall confer and attempt to resolve the grievance.

Regardless of which party has initiated the grievance proceeding, prior to a Step 2 meeting, the Union(s) shall notify its International Union representative(s), which shall advise both parties if it intends on participating in a Step 2 meeting. The Project Manager and the City shall have the right to participate in any efforts to resolve the dispute at Step 2.

A written opinion may be requested by a party from the presiding arbitrator.

The time limits specified in any step of the Grievance Procedure set forth in Section 12.2 may be extended by mutual agreement of the parties. However, failure to process a grievance within the time limits provided above, without an agreed upon extension of time, shall be deemed a waiver of such grievance without prejudice, or without precedent to the processing of and/or resolution of like or similar grievances or disputes.

In order to encourage the resolution of disputes and grievances at Steps 1 and 2 of this Grievance Procedure, the parties agree that such settlements shall not be precedent setting.

13.3 Should any of the arbitrators listed in this Article no longer work as a labor arbitrator, the City and the Council shall mutually agree to a replacement.

Filling the Good Jobs Gap: Fresno’s Opportunity for a
Citywide Project Labor Agreement

EXECUTIVE SUMMARY
A Project Labor Agreement (PLA)
guaranteeing wage levels, training standards,
local hires, and other working conditions for
municipal public construction projects is
currently under local government
consideration in Fresno, California. This
study finds that from January 2013 to
October 2020, an estimated 1,720
construction jobs in Fresno would have been
covered through such a municipal policy.

Prior University of California studies and
further independent research, reviewed here,
demonstrate the significant benefits of PLAs
for a diverse and locally inclusive workforce,
income, and career training with no
significant change in construction costs. In
the face of enduring poverty and a gap of
mid- and high-income careers in Fresno, a
municipal PLA represents an opportunity that
would support new or solidify existing
careers for 215 construction workers a year
on average, with immediate socioeconomic
benefits for their families and communities.

In just two decades, Fresno's policy
transformation–from an early prohibition on
PLAs, to growing PLA adoption with broad
official support–offers an instructive case for
cities and government bodies that have yet to
adopt this foundational labor policy. To
support such policy dissemination, this study
provides an analysis of the potential
construction job impacts of public PLAs.

BACKGROUND
For over sixty years, PLAs have been a
cornerstone of worker advocacy efforts for
equitable economic development in the
construction industry. A PLA is a pre-hire
contract negotiated between management
and one or more labor unions, which
standardizes job terms for a project, including
wages, benefits, and working conditions. In
turn, a PLA assures a steady labor force and
prohibits strikes or lockouts. PLAs may also
require quotas for local hires,
apprenticeships, and small business
participation. In California, over one hundred
cities and other public bodies have approved
PLAs to date, including over a dozen blanket
PLAs covering all public construction work
in a jurisdiction (Coalition for Fair
Employment Construction 2020).

In recent decades, non-union contractors
have sought to challenge the legality of PLAs
in public sector construction projects. These
opponents claim that PLAs reduce economic
competition and raise costs, by mandating
union wages that constrain the number of

2 bids on a project, and ultimately placing their
businesses at a disadvantage. In 1993, the
Supreme Court unanimously ruled against
Associated Builders and Contractors of
Massachusetts/Rhode Island, deciding that
the National Labor Relations Act does not
prohibit public entities from entering into
PLAs any more than private entities (U.S.

Supreme Court 1993). Associated Builders
and Contractors, the largest organization of
non-union contractors, responded with a
national campaign against PLAs. This led to
the first state-level preemptive laws striking
down local PLA mandates in Utah and
Montana. Following in the footsteps of rightto-work laws across the country, preemptive bans against public PLAs are now established
in 24 states (Associated Builders and
Contractors 2020).

Independent academic research, however,
has found a lack of empirical evidence for
claims made by PLA opponents. Prior
University of California research on
construction bids for projects among
California Community Colleges between
2007 and 2016–controlled for project size
and location, as well as business cycle and
season–found PLA policies did not affect the
number of bids (Philips and Waitzman 2017).

The study also found that the lowest bids on
projects with PLA agreements were no
higher in cost than those without PLA
agreements, and had fewer problems and
delays during construction. Similarly, an
analysis of PLAs on school construction
costs in Massachusetts found that higher PLA
costs were attributed to factors that underlie
PLAs, such as the size of the project (Belman
et al. 2010).

The City of Fresno is a unique and instructive
case of a transformation of PLA laws. In
2000, Fresno was one of the first jurisdictions
in the nation to ban PLAs (Wang 2012). In
2012, the California legislature passed a law
preventing state funding to municipal
projects in cities with bans on public PLAs.

By 2014, Fresno City Council turned around
to repeal its prior PLA ban (Calix 2019).

Next, in June 2019, Fresno's City Council
unanimously approved a PLA for the $115
million expansion of the Fresno Airport
(Watkins 2019). Soon after, in February
2020, the Board of Trustees at the Fresno
area's State Center Community College
District approved a PLA covering an
estimated $86.5M in construction on a new
West Fresno campus, including all
subcontracts of $600,000 or above (SCCD
2020).

These breakthrough policies followed a
decade in which PLAs became a standard
practice on private sector utility-scale solar
construction in the surrounding San Joaquin
Valley (Philips 2014), and on the estimated
$12.6B first segment of California's HighSpeed Rail from Fresno to Kern County (California High Speed Rail Authority 2019).

As California's fifth largest city, with an
estimated population of 531,576, Fresno is
characterized as both a major regional
economic hub and a stronghold of inequality.

According to US Census Bureau American
Community Survey 2014-2018 data, Fresno's
median household income ($50,432) is far
below the state average of ($71,228), and the
rate of household poverty (25.2%) was more
than double the state average (11.8%) (US
Census Bureau 2018).

To the extent which PLAs support higherpaying, career-track jobs, Fresno municipal public construction remains untapped
potential. On January 7, 2021, the Fresno
City Council showed strong interest in this
potential, as it approved (by a vote of 6-1) a
process to design a PLA policy proposal that
would cover municipal public construction
citywide.
3 DATA AND METHODS
This study utilizes public records from the
California Department of Industrial Relations
Public Works Registration Database (PWC100) (CDIR 2020). The analysis examines all 145 qualifying construction contracts issued
by the City of Fresno, and all 6 qualifying
contracts from the Fresno Housing Authority,
with listed construction start dates between
January 1st, 2013 and October 31st, 2020.

The analysis was limited to projects that
would have been affected by a hypothetical
municipal Project Labor Agreement. As a
result, contracts were included in this study
only if they were issued by the City of Fresno
or the Fresno Housing Authority, and met
one or more of the following three conditions
(all figures in adjusted 2020 dollars):
i. Contracts over $1M: Contract amount
listed at $1,000,000 or greater.
ii. Bond-funded contracts: Contract amount
over $500,000, with funding from a
municipal bond of at least $1,000,000, in
adjusted 2020 dollars. Bond data was
obtained from the City of Fresno's most
recently available Complete Bond Listing
(City of Fresno 2018).
iii. Multi-prime contracts: Contract amount
over $500,000, on a project site with multiple
contracts totaling of $1M or greater, in
adjusted 2020 dollars. This accounted for
only a small number of contracts identified in
the PWC-100 database.

These conditions were designed to follow the
parameters of a hypothetical Project Labor
Agreement for the City of Fresno and Fresno
Housing Authority, with one minor
exception. The $500,000 and above condition
for considering bond-funded and multi-prime
contracts was not indicative of expected
Project Labor Agreement terms, but instead a
means to expedite data collection and omit
small projects with only minor effects on
findings. This condition contributes to a more
conservative job estimates, as smaller bondfunded and multi-prime projects would likely add modestly to the total job estimates.

Each contract was classified with a single
North American Industry Classification
Scheme (NAICS) construction sub-sector
code, corresponding to the principal type of
work listed on the contract (for example,
"Highway, street, and bridge construction").

Where the principal type of work was
difficult to specify based on listed contract
data and publicly available city records,
contracts were classified a general NAICS
category (for example, "Heavy and civil
engineering construction").

Using data from the US Economic Census,
this study then estimated the annual full-time
equivalent jobs provided on each project.

Estimates of construction jobs on each
Fresno municipal project were created based
on California-specific construction sector
data from the 2017 US Economic Census, the
most recent year available (US Census
Bureau 2020). This Census data provided
specific construction sub-sector figures
(arranged by NAICS codes) for construction
workers on payroll each quarter, and for
combined annual sales, shipments, and
revenues (equivalent to a sum of construction
contract amounts). Construction worker job
figures are adjusted in the Census data to
reflect annual full-time equivalent (annual
FTE) jobs.

For each construction trade and subsector
listed, this study used Economic Census data
to derive a "job factor" for annual full-time
equivalent construction workers per
$1,000,000 in revenues. To create this factor,
the analysis divided the annual average of

FINDINGS
From 2013-2020, the distribution of Fresno
municipal construction contracts that
qualified for a potential PLA were primarily
projects over $1M in the water, sewer, and
road sub-sectors. More than two-thirds of
qualifying contracts were with the City of
Fresno in amounts greater than $1M (104 of
151 contracts) (see Table 2). Across the eight
years studied, Fresno city contracts above
$1M accounted for three-fourths (74.9%) of
the total dollar amount of qualifying Fresno
construction contracts ($94.8M of $126.5M)
(see Table 3). More than nine in ten (91.9%)
of the estimated jobs created by PLAqualified construction contracts in Fresno were generated by City of Fresno contracts in
excess of $1M (see Table 4). As shown in
Table 5, water and sewer projects made up a
strong majority of Fresno municipal
construction contract dollars (63.9%) and
jobs (68.8%) during this period.

full-time equivalent construction jobs could
have been covered by a Fresno municipal
PLA from 2013-2020, as summarized in
Table 6. Qualified Fresno municipal
construction spending of $126.5M, during
eight years, supported an average of 215 fulltime equivalent construction jobs each year.

This job estimate provides the first published
analysis of the specific potential job impact
of a municipal PLA in Fresno, through a
method that could be replicated for other
cities in California and beyond.

POLICY IMPLICATIONS
The estimated 1,720 construction jobs
without PLA standards represent missed
opportunities for stronger wages, career
training, and working conditions in one of
California's lowest-income major cities.

Research comparing similar union and nonunion jobs has shown that union jobs in the San Joaquin Valley provide higher wages of
an additional $7,000 per worker annually, on
average (Jacobs and Thomason 2018).

With this average wage increase to all
construction jobs estimated in this study, a
municipal PLA would have benefited Fresno
with over $1.5M per year, on average, in total
increased income for construction laborers.

These income benefits may in fact be greater,
as an additional study found that "those
workers who earn the least in non-union
workplaces gain the most" from union jobs
(Thomason and Bernhardt 2018).

Public-sector PLAs frequently include local
hire provisions that lead to diverse local
inclusion in unionized construction careers
(Waheed and Herrera 2014). From these
wage and inclusion benefits, University of
California studies have found a single union
job will "decrease by 30.6 percent the
likelihood that a worker is in a family where
at least one member is enrolled in a public
safety net program" (Jacobs and Thomason
2018), while providing a collective voice for
workers that is often lacking otherwise
(MacGillvary and Jacobs 2018).

Through support for union-affiliated training
programs, PLAs prepare a skilled labor force
that has lasting benefits to both public and
private-sector growth. In a report on solutions
for skilled construction labor shortages, the
Business Roundtable Construction Cost
Effectiveness Task Force concluded "(t)he
union sector has always excelled in craft
training through the joint labor/management
apprenticeship programs... but the open shop
[non-union] sector, as a whole, has not
supported formal craft training to the extent
necessary” (Business Roundtable 1997).

According to the available independent
academic studies, PLAs deliver these
benefits without increasing costs to
construction projects, while reducing project
delays. An independent study commissioned
by a California county agency found that
PLA projects had "fewer problems" during
construction than non-PLA projects, and
claimed the PLA "dispute resolution process
was an advantage" (Kelley et al. 2013). The
only existing comprehensive study of PLAs
and bid effects, analyzing 88 PLA and 175
non-PLA community college projects, shows
that PLAs did not increase the price or reduce
the number of construction bids. In fact, PLA
projects in that study received low bids that
were 5% cheaper on average than their nonPLA counterparts.

For a city aiming for broad prosperity, a
municipal PLA policy would offer rich
opportunity. The most recent Fresno General
Plan "envisions Fresno as a vibrant, growing
city, infused with a sense of heritage and
community"(City of Fresno Planning and
Development 2014). This study finds that a
8 municipal PLA for Fresno would benefit over
two hundred construction jobs per year on
average, along with benefits to construction.
completion and skilled workforce training,
towards city leaders' goals of vibrant growth.

FOR THE CITY OF MARTINEZ

INTRODUCTION/FINDINGS
This Project Labor Agreement is entered into this ____ day of _______________, 2019, by and between the City of Martinez (hereinafter the “City”), together with contractors and subcontractors of all tiers, who shall become signatory to this Agreement by signing the “Agreement to be Bound” (Addendum A) (referred to collectively herein as the “Contractors/Employers”), and the Contra Costa County Building & Construction Trades Council (hereinafter the “Council”) and its affiliated local Unions that have executed this Agreement (referred to collectively herein as the “Union” or “Unions”).

The purpose of this Agreement is to promote the efficiency of construction operations for the City of Martinez through the use of skilled labor resulting in quality construction outcomes, and to provide for the peaceful settlement of labor disputes and grievances without strikes or lockouts, thereby promoting the public interest in assuring the timely and economical completion of the Project.

WHEREAS, workers of various skills will be required in the performance of the construction work and will be represented by the Unions signatory to this Agreement and employed by contractors and subcontractors who are also signatory to this Agreement; and WHEREAS, the use of skilled labor on construction work increases the safety of construction projects as well as the quality of completed work; and WHEREAS, it is recognized that on Projects with multiple contractors and bargaining units on the job site at the same time over an extended period of time, the potential for work disruption may be substantial without an overriding commitment to maintain continuity of work; and WHEREAS, the interests of the general public, the City, the Unions and the Contractors/Employers would be best served if the construction work proceeded in an orderly manner without disruption because of strikes, sympathy strikes, work stoppages, picketing, lockouts, slowdowns or other interferences with work; and
WHEREAS, the Contractors/Employers and the Unions desire to mutually establish and stabilize wages, hours and working conditions for the workers employed on the Projects covered by this Agreement to the end that a satisfactory, continuous and harmonious relationship will exist among the parties to this Agreement; and
WHEREAS, the parties agree that one of the primary purposes of this Agreement is to avoid the tensions that might arise on the Project if Union and nonunion workers of different employers were to work side by side on the Project, potentially leading to labor disputes that could delay completion of the Project; and

ARTICLE IV

WORK STOPPAGES, STRIKES, SYMPATHY STRIKES AND LOCKOUTS

4.1 The Unions, City, and Contractor(s)/Employer(s) covered by this Agreement agree that for the duration of the Project:

4.1.1 There shall be no strikes, sympathy strikes, work stoppages, picketing, handbilling, slowdowns, withholding of work, unlawful refusals to work, lockouts, sickouts, walk-offs, sit-downs, stand-ins, boycotts, or other work stoppages, or otherwise advising the public that a labor dispute exists, or slowdowns of any kind, for any reason, by the Unions or employees employed on the Project, at the job site of the Project or at any other City facility because of a dispute on the Project.

Disputes arising between the Unions and Contractor(s)/Employer(s) on other City projects are not governed by the terms of this Agreement or this Article.

4.1.2 There shall be no lockout of any kind by a Contractor/Employer of workers employed on the Project.

4.1.3 Neither the Council nor local Unions may sanction, aid or abet, encourage or continue any work stoppage, strike, picketing or other disruptive activity prohibited by Section 4.1.1 at any Project site and shall undertake all reasonable means to prevent or to terminate any such activity.

No employee shall engage in activities which violate this Article. Any employee who engages in activities that violate this Article shall be subject to disciplinary action, including discharge.

4.1.4 If a Master Agreement expires before the Contractor/Employer completes the performance of work under a Construction Contract, the Union agrees that it will not strike on work covered by this Agreement or engage in any work disruption as described in Section 4.1.1 and the Union and the Contractor/Employer agree that the expired Master Agreement shall continue in full force and effect for work covered under this Agreement until a new or modified Master Agreement is reached. If the new or modified Master Agreement provides that any terms of the Master Agreement shall be retroactive, the Contractor/ Employer agrees to comply with any retroactive terms of the new or modified Master Agreement that are applicable to employees who were employed on the Project during the interim, with retroactive payment due within seven (7) calendar days of the effective date of the new or modified Master Agreement.

4.1.5 In the case of nonpayment of wages or trust fund contributions on the Project, the Union shall give the City and the Contractor/Employer(s) three (3) business days' notice when nonpayment of trust fund contributions has occurred and two (2) business days' notice when nonpayment of wages has occurred or when paychecks being tendered to a financial institution normally recognized to honor such paychecks will not honor such paycheck as a result of insufficient funds, of the intent to withhold labor from the Contractor/Employer(s)' or their subcontractor's workforce, during which time the Contractor/Employer(s) shall have the opportunity to correct the default. In this instance, a Union's withholding of labor (but not picketing) from a Contractor/Employer who has failed to pay its fringe benefit contributions or failed to meet its weekly payroll shall not be considered a violation of this Exhibit A - 11/6/19 Council Final redline
Project Labor Agreement for the City of Martinez
8 Article.

4.1.6 If the City contends that any Union has violated this Article, it will so notify in writing (including e-mail) the Senior Executive of the Council and the Senior Executive of the Union, setting forth the facts alleged to violate the Article, prior to instituting the expedited arbitration procedure set forth below. The Council will immediately use its best efforts to cause the cessation of any violation of this Article. The leadership of the Union will immediately inform the worker(s) of their obligations under this Article. A Union complying with this obligation shall not be held responsible for the unauthorized acts of employees it represents.

4.2 Expedited Arbitration: Any party to this Agreement shall institute the following procedure, prior to initiating any other action at law or equity, when a breach of this Article is alleged to have occurred:

4.2.1 A party invoking this procedure shall notify David Weinberg, as the permanent arbitrator, or Robert Hirsch, as the alternate arbitrator, under this procedure. In the event that the permanent arbitrator is unavailable at any time, the alternate will be contacted. If neither is available, then a selection shall be made from the list of arbitrators in Section 13.4. Notice to the arbitrator shall be by the most expeditious means available, with notices by facsimile, email or telephone to the City and the party alleged to be in violation, and to the Council and involved local Union if a Union is alleged to be in violation.

4.2.2 Upon receipt of said notice, the City will contact the permanent arbitrator named above, or the alternate if the permanent arbitrator is not available, who will attempt to convene a hearing within twenty-four (24) hours if it is contended that the violation still exists.

Said hearing shall be completed in one session, which, with appropriate recesses at the arbitrator's discretion, shall not exceed twenty-four (24) hours unless otherwise agreed upon by all parties. A failure of any party to attend said hearings shall not delay the hearing of evidence or the issuance of an award by the arbitrator.

4.2.4 The sole issue at the hearing shall be whether or not a violation of Section 4.1 of the Agreement has occurred. The arbitrator shall have no authority to consider any matter of justification, explanation or mitigation of such violation or to award damages, which issue is reserved for court proceedings, if any. The award shall be issued in writing within three (3) hours after the close of the hearing, and may be issued without a written opinion. If any party desires a written opinion, one shall be issued within fifteen (15) calendar days, but its issuance shall not delay compliance with or enforcement of the award. The arbitrator may order cessation of the violation of this Article and other appropriate relief and such award shall be served on all parties by hand or registered mail upon issuance.

Should a party found in violation of this Article fail to comply with an Arbitrator's award to cease the violation, the party in violation shall pay to the affected party as liquidated damages the sum of ten thousand dollars ($10,000.00) per shift for which it failed to comply, or portion thereof, until such violation is ceased. The Arbitrator shall retain jurisdiction to resolve any disputes regarding the liquidated damages claimed under this section.

4.2.5 Such award shall be final and binding and may be enforced by any Court of competent jurisdiction upon the filing of this Agreement and all other relevant documents referred to Exhibit A - 11/6/19 Council Final redline
Project Labor Agreement for the City of Martinez
9 above in the following manner. The party filing such enforcement proceedings shall give written notice to the other party. In the proceeding to obtain a temporary order enforcing the arbitrator's award as issued under this Article, all parties waive the right to a hearing and agree that such proceedings may be ex parte. Such agreement does not waive any party's right to participate in a proceeding for a final order or enforcement. The Court's order or orders enforcing the arbitrator's award shall be served on all parties by hand or delivered by certified mail.

4.2.6 Any rights created by statute or law governing arbitration proceedings inconsistent with the above procedure, or which interfere with compliance therewith, are waived by the parties.

4.2.7 The fees and expenses of the arbitrator shall be divided equally between the party instituting the arbitration proceedings provided in this Article and the party alleged to be in breach of its obligation under this Article.

8.3 In the event that referral facilities maintained by the Union(s) are unable to fill the requisition of a Contractor/Employer for employees within a forty-eight (48) hour period (Saturdays, Sundays and Holidays excluded) after such requisition is made by the Contractor/Employer, the Contractor/Employer shall be free to obtain the worker(s) from any source. A Contractor/Employer who hires a worker(s) to perform Covered Work on the Project pursuant to this section shall immediately provide the appropriate Union with the name and address of such employee(s) and shall immediately refer such employee(s) to the appropriate Union to satisfy the requirements of Article VII of this Agreement.

8.4 Core Workers. A Contractor may request by name, and the local Union shall honor, referral of Core Workers who qualify as Local Area residents have applied to the local Union for Project Work and who demonstrate to the Union dispatcher and provide satisfactory proof that the worker meets all the following qualifications:

Exhibit A - 11/6/19 Council Final redline
Project Labor Agreement for the City of Martinez

Upon request by any Party to this Agreement, the Contractor hiring any core workforce employee shall provide satisfactory proof (i.e., payroll records, quarterly tax records, and such other documentation) evidencing the worker’s qualification as a Core Worker to the City and the Council.

8.6 Referral: The Contractor/Employer shall be allowed to employ five (5) Core Workers pursuant to the following methodology: The Union will first refer to such Contractor one of the Contractor’s Core Workers and will then refer one employee from the applicable hiring hall.

Thereafter, all additional employees in the affected trade or craft shall be hired exclusively from the applicable hiring hall out-of-work list. For the duration of the Contractor’s work, this ratio shall be maintained and when the Contractor's workforce is reduced, employees shall be reduced in reverse order and in the same ratio of Core Workers to hiring hall referrals as was applied in the initial hiring.

13.6 The time limits specified at any step of these grievance procedures may be extended by mutual agreement of the parties.

13.7 In order to encourage the resolution of disputes and grievances at Steps 1 and 2, the parties agree that such settlements shall not be precedent setting.

13.8 Retention: In the event of a pending grievance regarding unpaid wages or benefits, the Council may request, that the City withhold retention payments and/or require the Contractor/Employer involved in the grievance to obtain a bond sufficient to cover the potential damages.

Each Contractor shall notify each of its contractors and subcontractors of the provisions of this Agreement and require as a condition precedent to the assigning, awarding or subcontracting of any Covered Work, or allowing any subcontracted Covered Work to be performed, that all such contractors and subcontractors at all tiers become signatory to this Agreement.

No employee shall engage in activities which violate this Article. Any employee who participates in or encourages any activities which interfere with the normal operation of the Project shall be subject to disciplinary action, including discharge, and, if justifiably discharged for the above reasons, shall not be eligible for rehire on the same project for a period of not less than ninety (90) days.

5.3 The Union(s) agrees that if any union or any other persons, whether parties to this Agreement or otherwise, engage in any picketing or work stoppages, the signatory Unions shall consider such work stoppage or picketing to be illegal and refuse to honor such picket line or work stoppage.

5.5 In addition to any other action at law or equity, any party may elect to have the matter decided by a neutral arbitrator in accordance with the following procedure when a breach of this Article is alleged, after the Union(s) or Contractor(s) has been notified of the fact.

5.5.1 A party invoking this procedure shall notify Robert Hirsch, as the permanent arbitrator, or Barry Winograd, as the alternate arbitrator under this procedure.

In the event that the permanent arbitrator is unavailable at any time, the alternate will be contacted. If neither is available, then the American Arbitration Association shall select an alternative arbitrator within 24 hours of notice. Notice to the Arbitrator shall be by the most expeditious means available, with notice by fax or electronic means or any other effective written means to the party alleged to be in violation and the involved International Union President and/or local Union.

5.5.2 Upon receipt of said notice, the Project Manager shall contact the designated Arbitrator named above or his alternate who will attempt to convene a hearing within twenty-four (24) hours if it is contended that the violation still exists.

5.5.3 The Arbitrator shall notify the parties by fax or electronic means or any other effective written means of the place and time he has chosen for this hearing.

Said hearing shall be completed in one session. A failure of any party or parties to attend said hearing shall not delay the hearing of evidence or issuance of an Award by the Arbitrator.

5.5.4 The sole issue at the hearing shall be whether or not a violation of this Article has in fact occurred. The Award which shall be final and binding shall be issued in writing within three (3) hours after the close of the hearing, and may be issued without an opinion. If any party desires an opinion, one shall be issued within fifteen (15) days, but its issuance shall not delay compliance with, or enforcement of, the Award. The Arbitrator may order cessation of the violation of this Article by the Union or Contractor, and such Award shall be served on all parties by hand or registered mail upon issuance. Should a party found in violation of this Article fail to comply with an Arbitrator’s award to cease the violation, the party in violation shall pay to the affected party as liquidated damages the sum of ten thousand dollars ($10,000) for the first shift for which it failed to comply, or portion thereof, and ten thousand dollars ($10,000) for each subsequent shift for which it failed to comply, until such violation is ceased. The Arbitrator shall retain jurisdiction to resolve any disputes regarding the liquidated damages claimed under this Section.

5.5.5 Such Award may be enforced by any court of competent jurisdiction upon the filing of this Agreement and all other relevant documents referred to hereinabove in the following manner. The fax or electronic notice of the filing of such enforcement proceedings shall be given to the other party. In the proceeding to obtain a temporary order enforcing the Arbitrator’s Award as issued under Section 5.5.4 of this Article, all parties waive the right to a hearing and agree that such proceedings may be ex parte. Such agreement does not waive any party’s right to participate in a hearing for a final order of enforcement. The Court’s order or orders enforcing the Arbitrator’s Award shall be served on all parties by hand or by delivery to their last known address or by certified mail.

5.5.6 Any rights created by statute or law governing arbitration proceedings inconsistent with the above procedure or which interfere with compliance therewith are hereby waived by the parties to whom they accrue.

5.5.7 The fees and expenses of the Arbitrator shall be borne by the party or parties found in violation, or in the event no violation is found, such fees and expenses shall be borne by the moving party.

5.6 The procedures contained in Section 5.5 shall be applicable to alleged violations of this Article. Disputes alleging violation of any other provision of this Agreement, including any underlying disputes alleged to be in justification, explanation or mitigation of any violation of this Article, shall be resolved under the grievance procedures of Article 9.

5.7 In the case of nonpayment of wages or trust fund contributions on the Project, the Union shall give the District and the Contractor(s) three (3) business days' notice when nonpayment of trust fund contributions has occurred and one (1) business day’s notice when nonpayment of wages has occurred or when paychecks being tendered to a financial institution normally recognized to honor such paychecks will not honor such paycheck as a result of insufficient funds, of the intent to withhold labor from the Contractor(s)' or their subcontractor's workforce, during which time the Contractor shall have the opportunity to correct the default. In this instance, a Union's withholding of labor (but not picketing) from an Contractor who has failed to pay its fringe benefit contributions or failed to meet its weekly payroll shall not be considered a violation of this Article. In the event the Union or any of its members withhold their services from such contractor or subcontractor, District shall have the right to replace such contractor or subcontractor with any other contractor or subcontractor who executes the Agreement to be Bound.

5.8 It will not be a violation of this Agreement when the Contractor considers it necessary to shut down to avoid the possible loss of human life because of an emergency situation that could endanger the life and safety of an employee. In such cases, employees will be compensated only for the actual time worked. In the case of a situation described above whereby the Contractor requests employees to wait in a designated area available for work, the employees will be compensated for the waiting time.

5.9 If a Master Agreement expires before the Contractor completes the performance of work under the Construction Contract and the Union or Contractor gives notice of demands for a new or modified Master Agreement, the Union agrees that it will not strike on work covered under this Agreement and the Union and the Contractor agree that the expired Master Agreement shall continue in full force and effect for work covered under this Agreement until a new or modified Master Agreement is reached.

If the new or modified Master Agreement provides that any terms of the Master Agreement shall be retroactive, the Contractor agrees to comply with any retroactive terms of the new or modified Master Agreement which are applicable to employees who were employed on the projects during the interim, with retroactive payment due within seven (7) days of the effective date of the modified Master Agreement subject to section 4.3.

ARTICLE 6

WORK ASSIGNMENTS AND JURISDICTIONAL DISPUTES

6.1 The assignment of Covered Work will be solely the responsibility of the Contractor performing the work involved; and such work assignments will be in accordance with the Plan for the Settlement of the Jurisdictional Disputes in the Construction Industry (the "Plan") or any successor Plan.

6.2 All jurisdictional disputes on this Project between or among the building and construction trades Unions and the Contractors parties to this Agreement, shall be settled and adjusted according to the present Plan established by the Building and Construction Trades Department or any other plan or method of procedure that may be adopted in the future by the Building and Construction Trades Department.

Decisions rendered shall be final, binding and conclusive on the Contractors and Unions parties to this Agreement.

6.3 If a dispute arising under this Article involves the Northern California Carpenters Regional Council or any of its subordinate bodies, an Arbitrator shall be chosen by the procedures specified in Article V, Section 5, of the Plan from a list composed of John Kagel, Thomas Angelo, Robert Hirsch, and Thomas Pagan, and the Arbitrator's hearing on the dispute shall be held at the offices of the California State Building and Construction Trades Council in Sacramento, California within fourteen (14) days of the selection of the Arbitrator. All other procedures shall be as specified in the Plan.

6.4 All jurisdictional disputes shall be resolved without the occurrence of any strike, work stoppage, or slow-down of any nature and the Contractor's assignment shall be adhered to until the dispute is resolved. Individual employees violating this section shall be subject to immediate discharge.

ARTICLE 7

JOINT LABOR/MANAGEMENT MEETINGS

7.1 Joint Labor/Management Meetings. During the period of any work performed under this Agreement, the Project Manager, or District designee, may schedule monthly Joint Labor/Management Meetings that include the Project Manager, or the District’s designee, the Contractors and the Unions. The purpose of these meetings is to promote harmonious labor/management relations, ensure adequate communications and advance the proficiency and efficiency of the employees and the Contractors on the Project. These meetings may include a discussion of safety, craft resource requirements, scheduling and productivity of work performed at the Project. The Union representative shall keep minutes of any such meetings and the minutes shall be subject to approval at any subsequent meeting. Any such meetings may be in person or by conference call. It shall be mandatory for a representative of the Unions to participate in such meetings.

7.2 A Pre-Job Conference shall be scheduled by the District prior to the commencement of work to establish the scope of work in each Contractor’s contract. When a contract has been let to a Contractor covered by this Agreement, a job conference and/or mark up meeting shall be scheduled by the District upon request of any Union, Contractor or the District.

ARTICLE 8

MANAGEMENT RIGHTS

8.1 The Contractor(s) retains full and exclusive authority for the management of their work forces for all work performed under this Agreement. This authority includes, but is not limited to the right to:

A. Plan, direct and control the operation of all the work.

B. Decide the number and types of employees required to perform the work safely and efficiently. The lawful staffing provisions of the applicable Master Agreement shall be recognized.

C. Hire, promote and layoff employees as deemed appropriate to meet work requirements and/or skills required.

D. Require all employees to observe the District and Contractor Project Rules, Security and Safety Regulations, consistent with the provisions of this Agreement. These Project Rules and Regulations shall be reviewed and mutually agreed upon at the Pre-Job meeting and supplied to all employees and/or posted on the jobsite.

E. Discharge, suspension or discipline will be handled under the applicable craft agreement.

F. Assign and schedule work at its sole discretion and determine when overtime will be worked. There shall be no refusal by a craft to perform work assigned, including overtime work. However, individual craftspeople shall not be required to work overtime unless specifically dispatched for overtime work. Any cases of a craft's refusal to work overtime shall be subject to the grievance procedure.

G. Utilize any work methods, procedures or techniques and select and use any type or kind of materials, apparatus or equipment regardless of source, manufacturer or designator (in accordance with Article 2).

H. The foregoing listing of management rights shall not be deemed to exclude other functions not specifically set forth herein. The Contractors, therefore, retain all legal rights not specifically enumerated in this Agreement.

8.2 All workers employed or otherwise used on a Project shall comply with the District’s Drug and Alcohol-Free Workplace Policy (BP 4020) and Employee Drug Testing Policy (BP 4112.41, 4212.41, 4312.41) and applicable regulations as amended from time to time. If not otherwise specified, the drug testing protocol shall be in compliance with 49 Code of Federal Regulations (CFR) section 382.105 (Testing procedures) which incorporates 49 CFR Part 40.

ARTICLE 9

GRIEVANCE PROCEDURE

9.1 It is mutually agreed that any question arising out of and during the term of this Agreement involving its interpretation and application (other than matters subject to Section 5.5 and Union jurisdictional disputes subject to Article 6) shall be considered a grievance. Questions between or among parties signatory to a Master Agreement arising out of or involving the interpretation of a Master Agreement shall be resolved under the grievance procedure provided in that Master Agreement.

9.2 The District and other Contractors, as well as the Unions, may bring forth grievances under this Article.

9.3 A grievance shall be considered null and void if not brought to the attention of the Contractor(s) within five (5) working days after the incident that initiated the alleged grievance occurred or was discovered, whichever is later. The term “working days” as used in this Article shall exclude Saturdays, Sundays or holidays regardless of whether any work is actually performed on such days.

9.4 Grievances shall be settled according to the following procedure, except that grievances that do not involve an individual grievant shall be discussed by the District, and the Council and then, if not resolved within five (5) working days of written notice unless extended by mutual consent, commence at Step 4:

Step 1
The Steward and the grievant shall attempt to resolve the grievance with the craft supervisor within five (5) working days after the Grievance has been brought to the attention of the Contractor.

Step 2
In the event the matter remains unresolved in Step 1 above after five (5) working days, within five (5) working days thereafter, the alleged grievance may be referred in writing to the Business Manager(s) of the Union(s) affected and the site construction manager or Labor Relations representative of the Contractor(s) for discussion and resolution. A copy of the written grievance shall also be mailed, faxed or emailed to the District.

Step 3
In the event the matter remains unresolved in Step 2 above within five (5) working days, within five (5) working days thereafter, the grievance may be referred in writing to the Business Manager(s) of the affected Union(s) involved and the Manager of Labor Relations of the Contractor(s) or the Manager’s designated representative and the District for discussion and resolution.

Step 4
If the grievance is not settled in Step 3 within five (5) working days, within five (5) days thereafter, either party may request the dispute be submitted to neutral arbitration or the time may be extended by mutual consent of both parties. The request for arbitration and/or the request for an extension of time must be in writing with a copy to the District. Should the parties be unable to mutually agree on the selection of a neutral Arbitrator, selection for that given arbitration shall be made by seeking a list of seven (7) labor arbitrators with construction experience from the Federal Mediation and Conciliation Service and alternately striking names from the list of names on the list until the parties agree on an Arbitrator or until one name remains.

The first party to strike a name from the list shall alternate between the party bringing forth the grievance and the party defending the grievance. District shall keep a record of the sequence and shall notify the parties to the grievance as to which party has the right to strike a name first.

9.5 The Arbitrator shall conduct a hearing at which the parties to the grievance shall be entitled to present testimonial and documentary evidence. Hearings will be transcribed by a certified court reporter. The parties shall be entitled to file written briefs after the close of the hearing and receipt of the transcript.

9.6 Upon expiration of the time for the parties to file briefs, the Arbitrator shall issue a written decision that will be served on all parties and on the District. The Arbitrator shall have the authority to utilize any equitable or legal remedy to prevent and/or cure any breach or threatened breach of this Agreement. The Arbitrator’s decision shall be final and binding as to all parties signatory to this Agreement.

9.7 The cost of the Arbitrator and the court reporter, and any cost to pay for facilities for the hearing, shall be borne equally by the parties to the grievance. All other costs and expenses in connection with the grievance hearing shall be borne by the party who incurs them.

9.8 The Arbitrator’s decision shall be confined to the issue(s) posed by the grievance, and the Arbitrator shall not have the authority to modify, amend, alter, add to or subtract from any provision of this Agreement.

9.9 Any party to a grievance may invite the District to participate in resolution of a grievance. The District may, at its own initiative, participate in Steps 1 through 3 of the grievance procedure.

9.10 In determining whether the time limits of Steps 2 through 4 of the grievance procedure have been met, a written referral or request shall be considered timely if it is personally delivered, sent by overnight mail or faxed within the five (5) working day period. Any of the time periods set forth in this Article may be extended in writing by mutual consent of the parties to the grievance, and any written referral or request shall be considered timely if it is personally delivered, sent by overnight mail or faxed during the extended time period.

ARTICLE 10

UNION SECURITY

10.1 The Contractors recognize the Unions signatory to this Agreement as the sole bargaining representative of all craft employees performing Covered Work for the Project.

10.2 All employees performing Covered Work shall, as a condition of employment on or before the eighth (8th) cumulative day of employment on the Project, be responsible for the payment of the applicable periodic working dues and any associated fees uniformly required for union membership in the local Union that is a signatory to this Agreement for the duration of his or her employment on the Project. Nothing in this Agreement is intended to prevent any non-union employees from joining the local Union.

10.3 Authorized representatives of the Unions shall have access to the Project whenever Covered Work is or will be performed on the Project. All authorized representatives of the Union must comply with the required uniform check-in procedure prior to visiting the work area.

10.4 Each Union shall have the right to designate a working journeyperson as a steward.

The steward shall be a qualified employee performing the work of that craft and shall not exercise any supervisory functions. Each steward shall be concerned with the employees of the steward’s Contractor and not with the employees of any other Contractor. A steward shall be allowed sufficient time to perform his duties.

ARTICLE 11

REFERRAL-LOCAL HIRE

11.1 Contractors performing Covered Work on the Project shall, in filling craft job vacancies, utilize and be bound by the registration facilities and referral systems established or authorized by the Unions signatory to this Agreement. Such Job Referral System shall be operated in a non-discriminatory manner and in full compliance with all federal, state, and local laws and regulations, including those which require equal employment opportunities and non-discrimination. The Contractor(s) shall have the right to reject any applicant referred by the Union(s), in accordance with the applicable Master Agreement. The Unions shall be the primary source of all craft labor employed on the Project, however, an Contractor with a core workforce may request by name, and the local Union shall honor, referral of such Contractor’s regular and experienced personnel (“Core Employees”) who have applied to the applicable Union to perform Covered Work on the Project. For purposes of this Agreement, a Core Employee is a person who meets all of the following:
(1) Possesses any license required by state or federal law for the Project work to be performed;
(2) Worked a total of at least one thousand (1,000) hours in the construction craft during the prior two (2) years;
(3) Has been on the Contractor’s active payroll for at least ninety (90) out of the one hundred and twenty (120) calendar days prior to the contract award; and
(4) Has the ability to perform safely the basic functions of the applicable trade.

11.2 The Union will refer to such Contractor one journeyman employee from the hiring hall out-of-work list for the affected trade or craft, and will then refer one of the Contractor’s Core Employees as a journeyman. The process will then be repeated, one for one, until such Contractor’s crew requirements are met, or until such Contractor has hired eight (8) Core Employees, whichever occurs first. Thereafter, all additional employees in the affected trade or craft shall be hired exclusively from the hiring hall out-of-work list(s). For the duration of the Contractor’s work on the Project, the ratio shall be maintained. When such Contractor’s workforce is reduced, employees shall be reduced in the same one for one ratio of Core Employees to hiring hall referrals as was applied in the initial hiring. Contractors that are signatory to a Master Agreement with Union(s) signatory hereto must comply with the hiring hall provisions contained in the applicable Master Agreement, and nothing in the referral provisions of this Agreement shall be construed to supersede the local hiring hall provisions of the Master Agreement(s) as they apply to such Contractors.

11.3 In the event the referral facilities maintained by the Unions do not refer the employees as requested by the Contractor within a forty-eight (48) hour period after such requisition is made by the Contractor (Saturdays, Sundays and holidays excepted), the Contractor may employ applicants from any source. Contractors shall immediately notify and provide the appropriate Union(s) with the name and address of such gate-hires, who shall be bound by the provisions of this Article.

11.4 It is in the interest of the parties to this Agreement to facilitate employment of District and Local Area residents, including parents, guardians or other care givers of students attending the District’s schools, and to use resources in the Local Area in construction of a Project. The “Local Area” shall be defined as the area within the boundaries of the District, the City of Sacramento and Sacramento County. To the extent allowed by law, and consistent with the Union’s hiring hall provisions, and as long as they possess the requisite skills and qualifications, residents of the Local Area shall be first referred for Project work, including journeymen and apprentices covered by this Agreement. It is the goal of the parties that not less than fifty (50) percent of all hours worked on the Project, on a craft by craft basis, be worked by residents of the Local Area (including fifty (50) percent of the total hours worked by any Core Employees). Contractors will be required to submit certified weekly payroll records to the District along with monthly workforce utilization reports documenting the Contractor’s compliance with the requirements described in this Article. At a minimum, the monthly reports must include: 1) data on Local Area resident work hour utilization on the Project; and 2) documentation showing any requests made to the Union dispatchers for Local Area residents and the Union’s response to the request. An annual report shall be submitted to the Board on the number of workers employed, or contracted for, within the Local Area.

ARTICLE 12

APPRENTICES

12.1 The parties recognize the need to maintain continuing support of programs designed to develop adequate numbers of competent workers in the construction industry, the Contractors will employ apprentices in the respective crafts to perform such work as is within their capabilities and which is customarily performed by the craft in which they are indentured.

12.2. Apprentices may comprise up to thirty (30) percent of each craft’s work force at any time, unless the state approved apprenticeship standards or regulations or the applicable Master Agreement establish a lower maximum percentage.

12.3 The parties agree to work with the Construction Technology Academy ("Academy'') as set forth in Attachment B in order to carry out the training and employment objectives of this Agreement, including providing District students with the opportunities and skills necessary to enter post-secondary study and to pursue lifelong training within the broader context of the building trades industry, and to develop and reinforce academic course standards in order to maximize career opportunities and technical competency.

ARTICLE 13

NON-DISCRIMINATION

13.1 The Unions and Contractors shall not discriminate against any employee or applicant for employment because of race, creed, color, sex, sexual orientation, political affiliation, national origin, age, religion, Vietnam veteran or Vietnam Era status, disability as identified in the Americans with Disabilities Act, membership in a labor organization in hiring and dispatching workers for the Project, or any other basis recognized by law. The parties to this Agreement understand and agree that nothing in this Agreement shall supersede or take precedence over any District Board of Education policy or requirement including, but not limited to, the construction contract and general conditions for the Project.

13.2 All qualified (as determined by the District and applicable law) contractors and subcontractors may bid and be awarded work on a Project without regard to whether they are otherwise parties to collective bargaining agreements provided they comply with the provisions of this Agreement.

ARTICLE 14

HOURS OF WORK, SHIFTS AND HOLIDAYS

14.1 The standard work day shall be in accordance with the applicable Master Agreements. Common start times may be established by the Contractor during the standard work day established by the applicable Master Agreements. The standard work week shall be five (5) consecutive days of work commencing on Monday.

Nothing herein shall be construed as guaranteeing any employee eight (8) hours of work per day or forty (40) hours of work per week.

14.2 Common shifts may be established when considered necessary by the Contractor.

The Contractor shall provide at least one week notice to the Council prior to any change in shift time. Any shifts established shall continue for the established work week.

14.3 Recognized holidays shall be in accordance with the applicable Master Agreements.

Under no circumstances shall any work be performed on Labor Day except in cases of emergency involving life or property. In the event a holiday falls on Saturday, the previous day, Friday, shall be observed as such holiday. In the event a holiday falls on Sunday, the following day, Monday, shall be observed as such holiday. There shall be no paid holidays. If employees are required to work on a holiday, they shall receive the appropriate rate, but in no case shall such overtime rate be more than double the straight time rate.

ARTICLE 15

GENERAL PROVISIONS

15.1 If any article or provision of this Agreement shall become invalid, inoperative and/or unenforceable by operation of law or by declaration of any competent authority of the executive, legislative, judicial or administrative branches of the federal or state government, the District, the Contractors and the Council shall suspend the operation of such article or provision during the period of its invalidity, and the District and the Council shall negotiate in its place and stead an article or provision that will satisfy the objections to its validity and that, to the greatest extent possible, will be in accord with the intent and purpose of the article or provision in question.

CITY COUNCIL
REPORT 12B
DATE: SEPTEMBER 20, 2022
TO: MAYOR AND COUNCIL MEMBERS
FROM: NEIL GANG, CHIEF OF POLICE
SUBJECT: HATE CRIME UPDATE

RECOMMENDATION
City staff recommends that the City Council accept an informational report on hate crimes in Pinole.

BACKGROUND
At its meeting on February 1, 2022, the City Council requested a future Council agenda item on hate crimes in Pinole.

The State recently released the 2021 Hate Crime in California Report. It indicated that overall, hate crimes reported in California increased 32.6% from 2020 to 2021, to 1,763 bias events, and are at their highest reported level since 2001.

According to the California Department of Justice, a hate crime is a crime against a person, group, or property motivated by the victim's real or perceived protected social group (disability, gender, nationality, race or ethnicity, religion, sexual orientation, and association with a person or group with one or more of these actual or perceived characteristics). A hate incident is an action or behavior motivated by hate but which, for one or more reasons, is not a crime. Examples of hate incidents include namecalling, insults, displaying hate material on your property, posting hate material that does not result in property damage, and distributing materials with hate messages in public places.

The City of Pinole has had two reported hate incidents over the past five years. The City realizes that this might not accurately reflect the number of community members that have experienced harassment and intimidation based on their race, gender, ethnicity, or sexual orientation. The City understands that specific hate incidents can go unreported, and members of the community may have experienced acts of aggression and/or intimidation.

City Council Report, 12B
September 20, 2022 2

REVIEW & ANALYSIS
As stated by California Attorney General Rob Bonta, “Crimes motivated by hate are not just attacks on individual innocent people, they are attacks on our communities and the entire State.”
The City believes everyone has a role in stopping bias and hate and creating a safe, inclusive community. The Police Department has the specific role of preventing and responding to hate crimes, like other crimes. Other City departments, particularly the Community Services Department, can play a role in promoting inclusivity in the community.

The Police Department strives to be aware of hate and bias incidents in the community through its multiple communication and engagement activities, including the work of the Community Outreach Unit and extensive social media communication. The Police Department strongly encourages members of the community to speak out against hate and report all incidents of possible hate crimes. Regarding hate crimes and other matters, it has and continues to be the philosophy of the Police Department that “No call is too small.” The City of Pinole has a zero-tolerance policy. The City encourages anyone who may be a victim or has witnessed hate crimes to report it to their local Police Department. When a law enforcement agency publicly prioritizes combating hate crimes, it sends the message that discrimination and harassment will not be tolerated.

To address hate incidents and crimes more actively, the City began participating in the national program United Against Hate Week (UAHW). This campaign brings together municipalities, school districts, and civic organizations to establish a network of support and resources so communities can respond to and prevent hate, foster inclusion, and promote equity for all. The City will be holding its first annual “Pinole United Against Hate” event at Fernandez Park on November 19, 2022, as well as undertaking additional activities to promote UAHW.
