2 Il. Introduction
In June 1988, the City Council confirmed the Engineer's Report, ordered improvements, and levied the first annual assessment for Citywide Landscaping and Lighting District 1988-01 (District 88-01). The assessment was originally set at $69.24 per benefit factor, increased to $77.18 per benefit factor in Fiscal Year (FY) 1990-91 and was affirmed by voters in the 1996 General Election.

This report is for FY 2022-23, the thirty-fifth fiscal year of the District's operation. For each parcel of land in the District, the report recommends assessments, which, when combined with a contribution from the general fund, are sufficient to fund the projected budget for operation, maintenance, servicing, replacement, and installation of District improvements.

Citywide Landscaping and Lighting Assessment District 1988-01 includes all the incorporated City of Pittsburg except Oak Hills Landscaping and Lighting Assessment District 1988-02 located along West Leland Road and Bailey Road. The assessment diagram depicting the boundaries of District 88-01 is on file in the Office of the City Clerk of the City of Pittsburg.

For FY 2007-08 and all years thereafter, the City increased the assessment for residential land use, (City category codes 01, 21, 22, 23, 24, 25 and 29), for a total assessment of $102.18 per benefit factor. All other parcels including commercial, institutional, industrial, churches, and non-profit will continue to pay the current assessment of $77.18 per benefit factor. In accordance with Proposition 218, the City conducted a mailed ballot election for the assessment increase.

Ill. Engineer’s Report
This Engineer's Report for the Citywide Landscaping and Lighting Assessment District 1988-01 is submitted, pursuant to Resolution 22-14086 of the Pittsburg City Council and under the provisions of the Landscaping and Lighting Act of 1972, Section 22500 through 22679 of the California Streets and Highways Code.

Part C: Method of Apportionment of Assessment —This section describes the assessment apportionment within the District based upon parcel classification in proportion to the estimated special benefit received by each parcel. 513
3 Part D: Assessment District Diagram —This part incorporates a diagram of the District showing the exterior boundaries and the boundaries of Landscaping and Lighting District 1988-02, which is also located within District 88-01. The lines and dimensions of each lot or parcel within the Assessment District are those lines and dimensions shown on the maps of the Assessor of the County of Contra Costa for the fiscal year when this report was prepared.

Part E: Property Owner List and Assessment Roll —This part contains a list of the assessor parcel numbers of Contra Costa County and the net amount to be assessed upon the benefited lands within the District for FY 2022-23. The list is keyed to the records of the Contra Costa Assessor Parcel Map numbers.

10 C. Method of Apportionment of Assessment
Calculation of Assessment and Assessment of New Parcels The City Engineer has developed and proposed an equitable method for distributing the costs of maintaining the City lighting, landscaping, and parks. That method:
 Determines the relative benefit received by each parcel based on type and intensity of land use
 Derives a numerical expression to determine the special benefit (benefit factor)  Determines the costs for maintenance of the District improvements  Derives an actual cost per unit of benefit (unit cost) by dividing the total estimated costs based on actual maintenance costs to cover all District cost by the total benefit factors
 Derives an applied assessment for each parcel based on an assessment per benefit factor of $102.18 for residential parcels and $77.18 for commercial, institutional, churches, parking lots, and non-profit parcels  Analyzes the actual costs per unit benefit for each parcel and the applied assessment for each parcel and calculates a City General Fund subsidy for all uses between actual District costs and applied assessment The assessment method asserts that: 1) all assessable parcels in the District benefit from the improvements because they are similarly distributed throughout the District; 2) the benefit for each property varies according to the use of the property and the intensity of that use, and for a given intensity of use, similar land uses will derive similar benefits; 3) the subsidy currently provided by the City is based on the actual maintenance cost to the District; 4) the subsidy currently provided to both residential and non-residential property is consistent with the goals of the community and City Council by offering a larger subsidy to commercial and industrial uses to increase economic development and generate/maintain jobs in the City; 5) the general benefit for the public at large is far less than the amount the City is currently contributing.

Newly developed areas within District 88-01 will be assessed if a final map has been recorded and the parcel has been created by the date established by the County Assessor’s Office for inclusion on the Assessment Roll. Vacant residential parcels are currently not assessed. Therefore, an assessment will be levied once a structure is declared final by the Engineering and Building Divisions.

The establishment of the District and its assessment methodology occurred prior to passage of Proposition 218. The provisions of Proposition 218 require that all parcels, including those that are owned by any agency (local, state, or federal) that benefit from the improvements within the District cannot be exempt from assessments “unless the agency can demonstrate by clear and convincing evidence that those publicly owned parcels in fact receive no special benefit.” Proposition 218 also requires that all existing, new, or increased assessments shall comply with the provisions of Proposition 218. Therefore, after the passage of Prop. 218, the City began imposing assessments on public property to ensure conformance with State law. The City has committed to subsidize 100% of the assessments to be levied on public school parcels in the City of Pittsburg. The subsidy for the public-school parcel assessment is $65,852. In addition, the General Fund will also pay the City assessments, which total $71,241, and the 521
11 Pittsburg Housing Authority assessments totaling $3,943. Other public parcels assessed under Lighting and Landscaping District 88-01 include but is not limited to the following agencies: Contra Costa County, Contra Costa County Fire Protection District, BART, and the State of California.

13 General Benefit
The City may only assess property owners for that portion of the costs which provide a special and direct benefit to the properties located within District boundaries. General benefits are not assessable, and the City must fund that portion of the improvements which provides a general benefit to the public at large with some other funding source, such as the general fund. The 1972 Act does not specify a formula or method to use when determining the amount of general versus special benefit. The Engineer of Work is responsible for conducting the general versus special benefit analysis and then making a recommendation to the City Council, which makes the final determination. The general benefit analysis is summarized below.

Street Lighting
The City recognizes that a portion of the maintenance, operation, and servicing of the City’s streetlights on arterial streets that are funded by the District provides a general benefit to the public at large. Therefore, the City contribution to the District for any general benefits incurred by the maintenance, operation, and services on arterial roadways is estimated to be 3% of the operation and maintenance cost. This estimate was derived by determining the percentage of arterial roadway included in the District and multiplying that by the percent benefit assumed for traffic operations. This amount totals $32,386 for FY 2022-23 Park Maintenance
The District provides operation and maintenance for approximately 250 acres of City-owned neighborhood and community parks, open space, and recreation facilities. For the purpose of calculating general benefit, it was assumed that casual park use by non-residents (park users not participating in a scheduled program) is de minimus because of the local nature of park use and the condition and popularity of parks in adjacent communities. Therefore, the general benefit derived for park and facility operation and maintenance is based solely on programs currently offered by the Pittsburg Recreation Department. It was estimated that 24% of the park area and facilities in the District have recreation programs offered. Based on data sampled, 15% of the participants registered for these programs for this year are non-residents. Lastly, it was estimated that 14% of the yearly daylight hours are being used by recreation programs offered by the Recreation Department. Therefore, the estimated general benefit for operation and maintenance for parks and facilities is .5% or $18,198 for FY 2022-23.

The total general benefit for FY 2022-23 is $50,584, which is less than 1% of the total cost to maintain the District. This amount will be paid out of the General Fund. It is anticipated that the general benefit will remain consistent each fiscal year and will be reassessed in 4 years to determine if any significant changes in estimates exist.
524
14 Residential Benefit
For residential parcels, the measure of the intensity of land use is based on the number of dwelling units on a parcel. Multiple dwelling unit residences receive increased benefits as the number of units on a parcel increase. However, the incremental benefit per unit decreases as the number of units increase. In other words, a single-family home's Benefit Factor is 1.00, a condominium's benefit factor is 0.75, a four-plex's Benefit Factor is 2.95. A four-plex does not have four times the special benefit of a single-family home, but its benefit is larger than that of a single-family home. Each additional unit in a residential complex adds benefit but less benefit than the previous unit added.

Commercial and Industrial Benefit
For nonresidential parcels, the intensity of use is based on the parcel's area and its frontage along public streets. Benefits from District improvements are estimated to rise with increasing parcel area and frontage. Once again, however, the incremental benefit per unit of area or frontage decreases with increasing parcel size or frontage.

Two separate land use categories are used for nonresidential parcels: industrial and commercial/institutional. These two nonresidential categories are further divided according to whether a parcel is developed or vacant. The assessment methodology estimates that the benefit to a vacant parcel is fifty (50) percent of the benefit to a developed one. Parking lots are defined as vacant commercial/institutional parcels and are thus assessed at the fifty (50) percent benefit level.

Mathematical Benefit Calculation
The total benefit estimate for a given benefit measure can be calculated from formulas determined by the Engineer of Work that closely estimate the special benefit. Those formulas, charts denoting benefit given parcel use and size, and sample calculations are on pages 16 through 25 of this report.

Assessment Calculation
After estimating the special benefits received by each parcel, the assessments are calculated. A parcel's assessment is determined by multiplying that parcel's benefit factors times the applied assessment per benefit factor. The applied assessment per benefit factor is $102.18 for residential uses and $77.18 for all others.

Cost estimates for FY 2022-23 operation, maintenance, and administration of the District are listed on Page 8. The assessment amount for each benefit factor for residential and other is determined as follows:

Commercial, Institutional, Industrial, Churches, and Non-Profit (“Other”) $165.80 less $77.18 $88.62 per benefit factor
For each land use category, Table 5 summarizes the number of parcels, the subtotal benefit factors, and the applied assessment per benefit factor. The applied assessment for a residential land use, City category codes 01, 21, 22, 23, 24, 25 and 29, is $102.18 per benefit factor. All other parcels including commercial, institutional, industrial, churches, and non-profit will pay $77.18 per benefit factor. This amount is still less than the actual assessment per benefit factor to cover all District costs based on actual maintenance costs, which is $165.80. Therefore, the City will continue to subsidize residential uses by $63.62 per benefit factor and non-residential uses by $88.62 per benefit factor. This is consistent with the goals of City Council and the community to encourage economic development and create/maintain jobs in the City of Pittsburg.

The resulting assessments for each parcel are listed on the assessment roll and are on file in the Office of the City Clerk of the City of Pittsburg. This list is available for review. 526
16 Calculation of Multi-Family Residential Assessment
The assessment for each parcel with a multi-family residential building is determined by multiplying the Residential Unit Assessment ($102.18) by the parcel benefit factor. The parcel's benefit factor is determined by the number of dwelling units on the parcel. The Engineer uses one of two formulas for the benefit factor calculation, B1 or B2 (below).

B1 is used to calculate the benefit for twenty-five (25) or fewer residential units, and B2 is used for parcels with more than twenty-five residential units.

Below are 1) the formulas used to calculate the benefit factors, and 2) examples of the calculation. Using these formulas, we have constructed tables showing the number of residential units and the corresponding benefit factors (see Appendix A).

Residential benefit cactor calculation uses either:

Formula B1 = RO x M + (S1 ÷ 2) x M2 or
Formula B2 = RO x MB + (S1 ÷ 2) x MB2 + RB x (M-MB) + (S2 ÷ 2) x (M-MB)2; Where,
M = Number of Dwelling Units
MB = 25
RO = 0.75
RB = 0.60
S1 = -0.006
S2 = -0.00038
Where,
B1 = benefit for a parcel with benefit measure falling within the first line segment of incremental benefit curve
B2 = benefit for a parcel with benefit measure falling within the second line segment of incremental benefit curve
M = benefit measure (e.g., number of dwelling units on a parcel) MB = value of benefit measure at the point where two-line segments meet (e.g., number of dwelling units on a parcel)
RO = incremental benefit at benefit measure of 0 (i.e., the y-intercept for incremental benefit curve) (e.g., SFR/dwelling unit)
RB = incremental benefit at point where the two-line segments meet (e.g., dwelling unit number or parcel area or parcel frontage) S1 = slope of first line segment of incremental benefit curve (e.g., dwelling unit number or parcel area or parcel frontage)
527
17 S2 = slope of second line segment of incremental benefit curve (e.g., dwelling unit number or parcel area or parcel frontage)
Substituting the above numbers for letters, the formulas may be simplified to read:

B1 = RO x M + (S1 ÷ 2) x M2
B1 = 0.75M - (0.006 ÷ 2) x M2
B1 = 0.75M - 0.003 x M2
B2 = RO x MB + (S1 ÷ 2) x MB2 + RB x (M-MB) + (S2 ÷ 2) x (M-MB)2 B2 = 0.75 x 25 - (0.006 ÷ 2) x 625 + 0.60 x (M-25) - (0.00038 ÷ 2) x (M-25)2 B2 = 18.75 - (0.003) x 625 + 0.60 x (M-25) - 0.00019 x (M-25)2 B2 = 18.75 - 1.875 + (0.60 x M) - 15 - 0.00019 x (M-25)2 B2 = 1.875 + 0.60M - 0.00019 x (M-25)2
Calculation examples are on the next page.

EXAMPLE 1. Find the benefit factors for a residential complex with sixteen (16) units. 16 units are less than twenty-five, so formula B1 "RO x M + (S1 ÷ 2) x M2" is used. That formula has been simplified for this example.

B1 = 0.75M - 0.003 x M2
M = 16
B1 = (0.75)(16) - (0.003)(162)
B1 = 12 - 0.768
B1 = 11.232 benefit factors
The assessment amount = benefit factors times the unit assessment The assessment amount = 11.232 x $102.18 = $1147.69 = $1147.70 EXAMPLE 2. Find the benefit factors for a residential complex with one hundred twenty units.
120 units are more than 25, so formula B2 [RO x MB + (S1 ÷ 2) x MB2 + RB x (MMB) + (S2 ÷ 2) x (M-MB)2 ] is used. That formula has been simplified for this example.

B2 = 1.875 + 0.60M - 0.00019 x (M-25)2
M = 120
B2 = 1.875 + 0.60 x 120 - 0.00019 x (120-25)2
B2 = 1.875 + 72 - 0.00019 x 9025
B2 = 73.875 - 1.71475
B2 = 72.160 Benefit Factors
The assessment amount = benefit factors times the unit assessment The assessment amount = 72.160 x $102.18 = $7,373.31 = $7,373.32 528

22 Calculation of Commercial Assessments
The assessment for each parcel with a commercial use building is determined by multiplying the unit assessment ($77.18) by that parcel's benefit factors. The parcel's benefit factors are determined by its area and street frontage. The formula for calculating a parcel's benefit factors is a detailed formula which places frontage and area on a curve corresponding to a special benefit factor rating. Separate formulas are used for calculating the number of benefit factors earned by the parcel's frontage and by its area.

Below are the formulas used to calculate the benefit factors for frontage and for area and an example of the calculation.

In the following formulas and example, please note:

F = actual parcel frontage x .75
A = parcel area (in acres)
B = benefit factor
FB1 Frontage Benefit Formula 1 (when frontage is <= 230') FB1 = 0.062 x F - (0.0002391304  2) x F2
FB2 Frontage Benefit Formula 2 (when frontage is > 230') FB2 = 7.935 + 0.007 x (F-230) - (0.0000022472  2) x (F-230)2 AB1 Area Benefit Formula 1 (when parcel area is <= 1.25 acres) AB1 = 28.0 x A - (21.6  2) x A2
AB2 Area Benefit Formula 2 (when parcel area is > 1.25 acres) AB2 = 18.125 + 1.0 x (A - 1.25) - (0.012903226  2) x (A-1.25)2 EXAMPLE: Find the assessment for an inside lot; 75' x 100' Step 1 Define the parameters:

F = 75' (actual parcel frontage) X .75 (multiplier)
A = 75' x 100' = 7500 square feet  43,560 = 0.172 acre (1 acre = 43,560 square feet)
Step 2 Calculate frontage benefit factors using formula FB1: (frontage is < 230') FB1 = 0.062 x F - (0.0002391304  2) x F2
F = 56.25'
533
23 FB1 = 0.062 x 56.25 - 0.0001195652 x 56.252
FB1 = 3.49 - 0.0001195652 x 3164
FB1 = 3.49 - 0.369
FB1 = 3.121 benefit factors
Step 3 Calculate area benefit factors using formula AB1 (area is < 1.25 acres) AB1 = 28.0 x A - (21.6  2) x A2
A = 0.172 acre
AB1 = 28.0 x 0.172 - 10.8 x 0.1722
AB1 = 4.816 - 10.8 x 0.030
AB1 = 4.816 - 0.324
AB1 = 4.492 benefit factors
Step 4 Find the total benefit factors earned by the parcel. benefit factors = FB1 + AB1
benefit factors = 3.121 + 4.492 = 7.613 benefit factors Step 5 Determine the landscaping and lighting assessment. assessment = unit assessment times benefit factors
assessment = $77.18 x 7.613 = $587.58
The above example assumes the parcel is developed. If the parcel is not developed, the assessment is 50% of the above figure.

Exceptions
Individually owned parcels and common area parcels of commercial and industrial condominiums are assigned a proration of the area and frontage, if applicable, to accommodate for the common area parcel.

Calculation of Industrial Assessments
The assessment for each parcel with an industrial use building is determined by multiplying the Industrial Unit Assessment ($77.18) by that parcels benefit factors.

The parcel's benefit factors are determined by its area and street frontage. The formula for calculating a parcel's benefit factors is a detailed formula which places frontage and area on a curve corresponding to a predetermined benefit factor rating.

Separate formulas are used for calculating the number of benefit factors earned by the parcel's frontage and by its area.

Below are the formulas used to calculate the benefit factors for frontage and for area and an example of the calculation.

24 In the following formulas and example, please note:

F = actual parcel frontage x .75
A = parcel area (in acres)
BF = benefit factor
FB1 frontage benefit formula 1 (when frontage is <= 1,000') FB1 = 0.026 x F - (0.000017  2) x F2
FB2 frontage benefit formula 2 (when frontage is > 1,000') FB2 = 17.5 + 0.009 x (F-1000) - (0.0000032  2) x (F-1000)2 AB1 area benefit formula 1 (when parcel area is <= 5.32 acres) AB1 = 14.75 x A - (2.678572  2) x A2
AB2 area benefit formula 2 (when parcel area is > 5.32 acres) AB2 = 40.565 + 0.5 x (A - 5.32) - (0.007032  2) x (A-5.32)2 EXAMPLE: Find the assessment for an inside lot; 250' x 400' Step 1 Define the parameters:

F = 250' (actual parcel frontage) x .75 (multiplier)
A = 250' x 400' = 100,000 square feet  43,560 = 2.30 acres (1 acre = 43,560 square feet)
Step 2 Calculate frontage benefit factors using formula FB1: (frontage is < 1,000') FB1 = 0.026 x F - (0.000017  2) x F2
F = 187.5'
FB1 = 0.026 x 187.5 - 0.0000085 x 187.52
FB1 = 0.026 x 187.5 - 0.0000085 x 35,156
FB1 = 4.875 - 0.299
FB1 = 4.576 benefit factors
Step 3 Calculate area benefit factors using formula AB1 (area is < 5.32 acres) AB1 = 14.75 x A - (2.678572  2) x A2
A = 2.30 acres
AB1 = 14.75 x 2.30 - 1.339286 x 2.302
AB1 = 14.75 x 2.30 - 1.339286 x 5.29
AB1 = 33.925 - 7.085
AB1 = 26.8402 benefit factors
535
25 Step 4 Find the total benefit factors earned by the parcel. benefit factors = FB1 + AB1
benefit factors = 4.576 + 26.8402 = 31.4162 benefit factors Step 5 Determine the landscaping and lighting assessment.

Assessment = unit assessment time benefit factors
Assessment = $77.18 x 31.4162 = $2,424.70
The above example assumes the parcel is developed. If the parcel is not developed, the Assessment is 50% of the above figure.

EXCEPTIONS
Each industrial parcel that has an area greater than seventy-six (76) acres are assigned, for purposes of assessment, an acreage of 76 acres, this being the point before the parcel area formula curve goes downward. Without such an assignment, the assessment for these parcels would have been less than for parcels of a smaller size.

MEETING DATE: July 18, 2022

EXECUTIVE SUMMARY
Oak Hills Landscaping and Lighting Assessment District 1988-02 (District 88-02) has been in existence since 1988, and the funds collected are necessary for the City to maintain the public-desired level of lighting and landscaping in the Oak Hills area. Each year prior to ordering the improvements and levying the assessments, the City Council holds a public hearing.

FISCAL IMPACT
Landscaping and Lighting District 88-02 will have a beginning fund balance of $70,017, collect $34,036 in assessments, transfer-in $1,500 from the General Fund for General Benefit, and collect $480 in other interest revenue.

The Public Works Department estimates that Fiscal Year (FY) 2022-23 expenditures for managing District 88-02 will be $41,038.

Without the District, the General Fund would be responsible for the entire cost of maintaining the improvements located within the Oak Hills area.

RECOMMENDATION

Il. Introduction
In June 1988, the City Council confirmed the Engineer's Report, ordered improvements, and levied the first annual assessment for Oak Hills Landscaping and Lighting District 1988-02 (District). The assessment was originally set at $69.24 per benefit factor, increased to $77.18 per benefit factor in Fiscal Year (FY) 1990-01, and was affirmed by voters in the 1996 General Election.

The boundaries of the District are depicted on the Assessment District Diagram on file in the Office of the City Clerk. The Oak Hills Landscaping and Lighting District 1988-02 is separate and distinct from Citywide Landscaping and Lighting District 1988-01.

IIl. Engineer’s Report
This Engineer's Report for Oak Hills Landscaping and Lighting Assessment District 1988-02 is submitted pursuant to Resolution 22-14087 of the Pittsburg City Council and under the provisions of the Landscaping and Lighting Act of 1972, Section 22500 through 22679 of the California Streets and Highways Code. The report is on file with the City Clerk.

I, Richard D. Abono, the duly appointed Engineer of Work, Assessment Engineer for the Oak Hills Landscaping and Lighting District 1988-02, submit the following Report consisting of three sections and including the following six parts:

4. 546
C. Method of Apportionment of Assessment
Calculation of Assessment and Assessment of New Parcels The City Engineer has developed and proposed an equitable method for distributing the costs of maintaining the City lighting, landscaping, and parks. That method:
 Determines the relative benefit received by each parcel based on type and intensity of land use
 Derives a numerical expression to determine the special benefit (benefit factor)  Determines the costs for maintenance of the District improvements  Derives an actual cost per unit of benefit (unit cost) by dividing the total estimated costs based on actual maintenance costs to cover all District cost by the total benefit factors
 Derives an applied assessment for each parcel based on an assessment per benefit factor of $77.18 for residential parcels
 Analyzes the actual costs per unit benefit for each parcel and the applied assessment for each parcel and calculates a City General Fund subsidy for all uses between actual District costs and applied assessment The assessment method asserts that: 1) all assessable parcels in the District benefit from the improvements because they are similarly distributed throughout the District; 2) the benefit for each property varies according to the use of the property and the intensity of that use, and for a given intensity of use, similar land uses will derive similar benefits; 3) any subsidy currently provided by the City is based on the actual maintenance cost to the District.

Vacant residential parcels are currently not assessed. Therefore, an assessment will be levied once a structure is declared final by the City of Pittsburg’s Building Division.

The establishment of the LLAD and its assessment methodology occurred prior to passage of Proposition 218. The provisions of Proposition 218 require that all parcels, including those that are owned by any agency (local, state or federal), that benefit from the improvements within the District cannot be exempt from assessments “unless the agency can demonstrate by clear and convincing evidence that those publicly owned parcels in fact receive no special benefit.” Proposition 218 also requires that all existing, new, or increased assessments shall comply with the provisions of Proposition 218. Therefore, after the passage of Prop. 218, the City began imposing assessments on public property to ensure conformance with State law. The City has however, committed to subsidize 100% of the assessments to be levied on public school parcels in the City of Pittsburg, though there are no school parcels in District 88-02.

5. 547
General Benefit
The City may only assess property owners for that portion of the costs which provide a special and direct benefit to the properties located within the boundaries of the District. General benefits are not assessable, and the City must fund that portion of the improvements which provides a general benefit to the public at large with some other funding source, such as the general fund. The 1972 Act does not specify a formula or method to use when determining the amount of general versus special benefit. The Engineer of Work is responsible for conducting the general versus special benefit analysis and then making a recommendation to the City Council, which makes the final determination. The general benefit analysis is summarized below.

Street Lighting
The City recognizes that a portion of the City’s nine street lights on West Leland Road, an arterial street that is included in the District, provides a general benefit to the public at large. Therefore, the City’s contribution to the District for general benefits incurred by the operation of higher wattage street lighting on this arterial roadway is estimated to be $1,500 or 6.6% of the electrical cost for FY 2022-23. This estimate was derived by determining a per wattage rate for all street lighting in the district and multiplying that by the additional wattage required to operate these nine street lights located along the arterial roadway.

Of the 443 parcels in the District, 441 are used as residences, two are open space (non-assessable), and one City-owned pump station. Benefits to family residences and the City pump station are estimated to be uniform throughout the District. Therefore, each residential parcel and the City’s pump station are assessed an equal amount, simply calculated by dividing the District's net cost of the improvements by the number of assessable parcels.

OFFICE OF THE CITY MANAGER/EXECUTIVE DIRECTOR
65 Civic Avenue
Pittsburg, CA 94565
TO: Mayor and Council Members
FROM: Garrett Evans, City Manager
SUBJECT: By Minute Order, Receive Triennial Report on Drinking Water Public Health Goals
MEETING DATE: July 18, 2022

EXECUTIVE SUMMARY
Public water systems with more than 10,000 service connections must prepare a written report every three years that gives information on the detection of any contaminant above Public Health Goals established by the California Office of Environmental Health Hazards Assessment. The attached report is intended to provide information to the public and is prepared in addition to the Annual Water Quality Report made available every year to all Pittsburg water customers.

FISCAL IMPACT
This item has no fiscal impact.

RECOMMENDATION
City Council open the public hearing, accept public comments, close the public hearing, and receive and file by Minute Order the Triennial Report on Drinking Water Public Health Goals.

BACKGROUND
In 1997, SB 1307 added provisions to the California Health and Safety Code, which require that a brief written report in plain language be prepared every three years if test results exceed a maximum contaminant level goal or public health goal. Only those substances, also referred to as constituents, that have a California primary drinking water standard and goal are required to be addressed in the report.

The Triennial Report on Drinking Water Public Health Goals for the City of Pittsburg Water System compares the City’s drinking water quality with Public Health Goals (PHGs) adopted by the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) and with Maximum Contaminant Level Goals (MCLGs) adopted by 558
the U.S. Environmental Protection Agency (USEPA). PHGs and MCLGs are not enforceable standards but are included in the report as part of the analysis. The report covers constituents detected in the City’s water supply during calendar years 2019 through 2021 at a level exceeding an applicable goal and provides the required information for each.

This report provides the information required by law, including identifying the best treatment technology currently available to reduce the constituent level and an estimate of the cost to install that treatment if it is appropriate and feasible.

The Association of California Water Agencies (ACWA) formed a workgroup, which prepared guidelines for water utilities to use in preparing these required reports. Public Works staff utilized the ACWA’s guidelines in the absence of guidance from State regulatory agencies.

SUBCOMMITTEE FINDINGS
This item was not presented to a subcommittee.

STAFF ANALYSIS
The City’s water system complies with all health-based drinking water standards and levels required by the California Department of Health Services and the USEPA. The City’s water system routinely meets the enforceable and mandatory standard of water purity and acceptability known as Maximum Contaminant Level (MCL).

State Public Health Goals (PHG) or Federal (MCLG) differ from MCLs in that they are not enforceable and represent an ideal standard of water purity and acceptability if cost were not a concern and near perfection was technically possible.

The City of Pittsburg Water System’s drinking water quality meets all State and USEPA drinking water standards set to protect public health.

The levels of constituents identified in this report are significantly below the health based MCLs established to provide safe drinking water. Therefore, no action is proposed at this time.

1 SECTION 1: BACKGROUND INFORMATION
Reporting Requirements:

The California Health and Safety Code Section 116470 (b) specifies that water utilities serving more than 10,000 connections prepare a brief written report every three years that documents detections of any constituents that exceed a Public Health Goal (PHG) in the preceding three years. PHGs are non-enforceable goals established by the California Office of Environmental Health Hazard Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a constituent, the water suppliers are to use the Maximum Contaminant Level Goal (MCLG) adopted by the United States Environmental Protection Agency (USEPA). Only constituents that have both a California primary drinking water standard and a PHG or MCLG are to be addressed in the report.

The City of Pittsburg prepared the last Triennial PHG Report in 2019. The 2022 Triennial PHG Report covers constituents detected in the City of Pittsburg’s water supply during calendar years 2019 through 2021 at a level exceeding an applicable PHG or MCLG and provides the required information for each constituent. Included is the numerical public health risk associated with the Maximum Contaminant Level (MCL) and the PHG or MCLG, the category or type of risk to health that could be associated with each constituent, the best treatment technology available that could be used to reduce the constituent level, and an estimate of the cost to install that treatment if it is appropriate and feasible.

What are Public Health Goals (PHGs) and Maximum Contaminant Level Goals (MCLGs)? PHGs are set by OEHHA and are based solely on public health risk considerations. None of the practical risk-management factors that are considered by the USEPA or the California State Water Resources Control Board, Division of Drinking Water (DDW) in setting drinking water standards are considered in setting the PHGs. These factors include analytical detection capability, treatment technology available, benefits and costs. The PHGs are not enforceable and are not required to be met by any public water system. MCLGs are the federal equivalent to PHGs.

Water Quality Data Considered:

All of the water quality data collected by the City of Pittsburg Water System between 2019 and 2021 for the purposes of determining compliance with drinking water standards was considered.

This data was summarized in our 2019, 2020, and 2021 Annual Water Quality Reports which are made available each year, in June, to all the City’s customers. The Annual Water Quality Report is also available at City Hall and on the City’s website.

For each regulated contaminant, DDW establishes Detection Limits for the purpose of Reporting (DLRs). DLRs are the minimum levels at which any analytical result must be reported to DDW.

Results detected below the DLR cannot be quantified with any certainty. In some cases, PHGs are set below the DLR (Exhibit A).
562
2 Guidelines Followed:

The Association of California Water Agencies (ACWA) formed a workgroup in 2004 to establish guidelines for water utilities to use in preparing these reports. The guidelines were updated in 2022 and were utilized in the preparation of this report. No formal guidance was available from state regulatory agencies.

Best Available Treatment Technology and Cost Estimates:

Both the USEPA and Division of Drinking Water (DDW) have identified best available technologies that are the best-known methods of reducing contaminant levels to the MCL. Costs can be estimated for such technologies. However, since many PHGs and all MCLGs are set much lower than the MCL, it is not always possible or feasible to determine what treatment is needed to further reduce a constituent downward to or near the PHG or MCLG, many of which are set at zero. Estimating the costs to reduce a constituent to zero is difficult, because it is not possible to verify by analytical means that the level has been lowered to zero. In some cases, installing treatment to further reduce very low levels of one constituent may have adverse effects on other aspects of water quality.

SECTION 2: CONTITUENTS DETECTED THAT EXCEED THE PHGs OR MCLGs The following is a discussion of constituents that were detected in the City’s drinking water sources at levels above a Public Health Goal (PHG), or if no PHG, above the Maximum Contaminant Level Goal (MCLG).

Arsenic
Arsenic is a naturally occurring element in the earth's crust and is very widely distributed in the environment. All humans are exposed to microgram quantities of arsenic (Inorganic and organic) largely from food (25 to 50 µg/day) and to a lesser degree from drinking water and air. Some edible seafood may contain higher concentrations of arsenic which is predominantly in less acutely toxic organic forms.

The City of Pittsburg utilizes groundwater from the Bodega, and Dover wells for a portion of its the source water. Depending on the geology of the area in which wells are drilled, arsenic can be found as a natural mineral, which can impact the quality of the water bearing aquifer. The primary MCL for arsenic was reduced from 0.05 milligrams per liter (mg/L) in January 2006 to the current limit of 0.01 mg/L. The current PHG for arsenic is 0.000004 mg/L, significantly less than the analytical capability reflected in the DLR of 0.002 mg/L.

The City of Pittsburg meets the MCL for arsenic. The City's routine is to monitor annually for arsenic in its treated water. Test results from 2019, 2020 and 2021 showed no detectable level of arsenic in treated water. The average from the triennial period result to the current date has met the PHG level.

Water Source 2019 2020 2021
Treated water ND 0.0021 ND
Average = ND (lower than Detection Limit to Report)
Chlorite
In 2018, the City of Pittsburg implemented the use of chlorine dioxide as a pre-oxidant prior to monochlorination of drinking water to destroy natural water impurities that would otherwise produce trihalomethanes, leads to the formation of the by-product chlorite. The MCL for chlorite is 1 ppm (part per million), with a PHG of 0.05 ppm.

The PHG is based on hematological effects observed in offspring at 3 mg/kg-day and higher in a two-generation rat reproductive study. There are no acceptable carcinogenicity studies on chlorite. Several of these studies (sub chronic, chronic, and developmental) reveal that oral exposure to chlorite can result in significant hematological, endocrine, reproductive, and gastrointestinal effects as well as changes in neurobehavioral development.

The USEPA Maximum Contaminant Level Goal (MCLG) for chlorite is 0.8 mg/L. This value is based on the same study utilized by OEHHA (CMA, 1996), but inferring a no observed adverse effect level (NOAEL) of 3 mg/kg-day based on the reduced response to auditory stimuli. The USEPA calculated a reference dose (RfD) of 0.03 mg/kg-day, using a combined uncertainty factor of 100 (U.S. EPA 1998a, b, 2000). Their recommended health-protective chlorite level (the MCLG) is calculated using adult water consumption values.

The City of Pittsburg collected and analyzed 108 samples for chlorite during 2019-2021, with values that ranged from ND (not detected) to 0.45 ppm, with all sample results at or below the MCL. The BAT for chlorite reduction is reverse osmosis (RO).

Radiological Standards
Radionuclides (Radium-226 and Radium-228, and Gross Alpha materials) are commonly detected in groundwater in quantities above the Public Health Goals. In the treated drinking water, the City of Pittsburg meets the MCL for Radionuclides. The City does routine annual monitoring for radionuclides in its treated water. The 2019, 2020 and 2021. Result for treated water was ND (not detected), well below the PHG level.

Uranium
The City of Pittsburg utilizes groundwater from the Bodega, and Dover wells for a portion of its source water. Depending on the geology of the area in which wells are drilled, Uranium can be found as a natural mineral, which can impact the quality of the water bearing aquifer. Uranium is a naturally occurring radioactive element present in geological formations and the earth’s crust. 564
4 It is introduced into groundwater and surface water through erosion. DDW has set the drinking water standard for uranium at MCL for uranium is 20 pCi/L and the PHG for uranium is 0.5 pCi/L, although the DLR is set at 1 pCi/L.

The City of Pittsburg collected and analyzed 3 samples for uranium during 2019-2021, with values that ranged from ND to 1.27 pCi/L, with an average value of 1.00 pCi/L, with all samples below the MCL.

The average from the triennial period result for the current date has met the PHG level.

The major source of uranium in drinking water is from erosion of natural deposits. Some people who drink water containing uranium in excess of the MCL over many years may have kidney problems or an increased risk of cancer. The best available technology (BAT) for removal of uranium has been identified as ion exchange and reverse osmosis.

2 Cancer Risk = theoretical 70-year lifetime excess cancer risk at the statistical upper confidence limit. Actual cancer risk may be lower or zero. Cancer risk is stated in terms of excess cancer cases per million (or fewer) population, e.g., 1×10-6 means one excess cancer case per million people; 5×10-5 means five excess cancer cases per 100,000 people.

MCL = maximum contaminant level.
mg/L = milligrams per liter of water or parts per million (ppm) (PHGs are expressed here in milligrams per liter for consistency with the typical unit used for MCLs and MCLGs.) ND = non-detect
pCi/L = picocuries per liter; a picocurie (pCi) is a unit of measurement for radionuclides that measures the number of disintegrations per second. For uranium: 0.001 mg (mass) = 0.72 pCi. (activity) 565
5 SECTION 3: COST ESTIMATES FOR TREATING PHG/MCLG CHEMICALS The City uses about 490 – 650 million gallons (1,500 – 2,000-acre feet) of groundwater each year.

This represents about 15% of the City’s water supply. The two chemicals discussed in this PHG Report are found in the groundwater. One option would be to discontinue use of the groundwater sources. The difference in cost between using the City’s wells and buying water from Contra Costa Water District is about $ 795 per acre foot. The cost of changing water sources would increase the cost of water by about $ 1,192,500 per year, for 1,500-acre feet of water.

Arsenic:

The most common technologies used for arsenic removal are coagulation/filtration and adsorption. The City of Pittsburg Water currently uses coagulation/filtration in its water treatment process.

Adsorption is a more passive process but can have higher operating costs for challenging waters when compared to coagulation/filtration. The latter entails more operator interface and routine sludge handling. Arsenic treatment for groundwater supplies uses Ion Exchange or Granular Ferric Oxidation (GFO). Treatment cost is estimated at $ 2.40 per 1,000 gallons or $1,173,064 per year. Adsorption treatment techniques produce a waste that might be classified as hazardous.

The average from the triennial period result to the current date has met the PHG level.

Radionuclides (Uranium):

Ion exchange and Reverse Osmosis have been identified by California Department of Public Health as a Best Available Technology (BAT) that can effectively lower the level of Uranium below the MCL.

While Uranium was with values that ranged from ND to 1.27 pCi/L, with an average value of 1.00 pCi/L, with all samples below the MCL for treated drinking water in 2019, 2020 or 2021, the prevalent source for the uranium comes from the groundwater supply. The estimated cost to install and operate an Ion Exchange treatment system that would effectively reduce the Uranium level below the PHG in treated water is estimated at $520,000 annually, including capital and operation costs. When MCLGs are set at zero, there may not be commercially available technology to reach a non-detectable level. Since there is little data readily available to “estimate” cost of treatment to achieve absolute zero levels, rough estimates of BAT as defined are provided.

This may still not achieve the PHG or MCLGs and the costs may be significantly higher to do so.

There are no current cost estimates available.

d The combination of variable source water quality and the complexity of the water chemistry involved may make this technology too complex for small systems.
e This would involve modification to a coagulation/filtration process already in place.

Chlorite
Both the USEPA and DDW adopt what are known as BATs or Best Available Technologies, which are the best-known methods of reducing contaminant levels to the MCL. Costs can be estimated for such technologies. However, since many PHGs and all MCLGs are set much lower than the MCL, it is not always possible, nor feasible, to determine what treatment is needed to further reduce a constituent downward to or near the PHG or MCLG, many of which are set at zero.

Estimating the costs to reduce a constituent to zero is difficult, if not impossible, because it is not possible to verify by analytical means that the level has been lowered to zero. In some cases, installing treatment to try and further reduce very low levels of one constituent may have adverse effects on other aspects of water quality.

The best available technology (BAT) to lower the level of chlorite below the PHG is reverse osmosis. Since the levels are already below the MCL, reverse osmosis would be required to attempt to lower the levels to below the PHG. Please note that accurate cost estimates are difficult, if not impossible, and are highly speculative and theoretical. All costs include annualized capital, construction, engineering, planning, environmental, contingency, and operations & management, but only very general assumptions can be made for most of these items. Costs for BAT implementation were estimated using the Association of California Water Agency’s (ACWA) guidance report. According to the ACWA’s Cost Estimates for Treatment Technology BAT, installation and operation of a RO system would cost approximately $ 0.94 per 1,000 gallons of water treated, or $459,500 per year. There would be added costs for water conditioning to ensure water treated by reverse osmosis is optimized for distribution system corrosion control. 567
7 SECTION 4: RECOMMENDATIONS
The City of Pittsburg Water System’s drinking water quality meets all the drinking water standards set by the USEPA and the California State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW) to protect public health.

The levels of constituents identified in this report are already significantly below the health based MCLs established to provide safe drinking water. Further reductions in these levels would not only require alternatives involving a notable increase in supply costs but would include the additional expense to alter treatment processes with what remains the uncertain ability to achieve substantial reductions in constituent levels. In addition, the health protection benefits of these possible reductions are not at all clear and may not be quantifiable. Therefore, no action is proposed at this time.

2 2019 ANNUAL WATER QUALITY REPORT

SAFETY STANDARDS ENSURE QUALITY
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

CONTAMINANTS THAT MAY BE PRESENT

IN SOURCE WATER
Microbial contaminants include viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants include salts and metals that can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.

Organic chemical contaminants include synthetic and volatile organic chemicals that are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, agricultural application and septic systems.

Pesticides and herbicides may come from a variety of sources, such as agriculture, urban stormwater runoff and residential uses.

Radioactive contaminants can be naturally occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, the U.S.

Environmental Protection Agency (US EPA) and the State Water Resources Control Board (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. State Board regulations also establish limits for contaminants in bottled water that provide the same protection for public health.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.

The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the US EPA’s Safe Drinking Water Hotline (1-800-426-4791).

None of the public water systems listed in this report produce or distribute bottled water. The State Division of Drinking Water mandates that the statements about bottled water be included in this report.

IMPORTANT NOTICE
Some people may be more
vulnerable to contaminants
in drinking water than the
general population. Immunocompromised persons such
as persons with cancer
undergoing chemotherapy,
persons who have undergone
organ transplants, people
with HIV/AIDS or other
immune system disorders,
some elderly, and infants
can be particularly at risk
from infections. These
people should seek advice
about drinking water from
their health care providers.

USEPA/Centers for Disease
Control (CDC) guidelines
on appropriate means to
lessen the risk of infection by
Cryptosporidium and other
microbial contaminants
are available from the Safe
Drinking Water Hotline at
1-800-426-4791.

Water treatment plants provide the drinking water delivered to homes and businesses throughout our service area. In addition to routine maintenance performed each year, in 2019, Contra Costa Water District renovated the power distribution system, improved chemical storage, and performed other safety projects.

2019 ANNUAL WATER QUALITY REPORT 3

WATER QUALITY NOTIFICATIONS

LEAD IN DRINKING WATER
No water provider included in this report detected lead above the regulatory action level in their water supply. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and plumbing in buildings and homes. Your drinking water supplier is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to two minutes before using water for drinking or cooking. If you do so, you may wish to collect the flushed water and reuse it for another beneficial purpose, such as watering plants. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 1-800-426-4791 or at epa.gov/lead.

LEAD MONITORING IN SCHOOLS
In early 2017, the State Board issued amendments to domestic water supply permits of community water systems so that kindergarten through 12th grade (K–12) schools could request assistance from their water provider to conduct water sampling for lead and receive technical assistance if an elevated lead sample was found. To further safeguard water quality in California’s K–12 public schools, California Assembly Bill 746, effective January 1, 2018, required community water systems to test lead levels in drinking water at all California public K–12 schools, preschools, and child care facilities located on public school property constructed before January 1, 2010.

Your water providers assisted local schools in our service area.

Testing at schools on public property was completed by July 1, 2019, as required, while testing at private schools remained voluntary. Please see the tables on pages 7–11 to find out how many schools requested sampling in 2019. To find
out more about the Lead Sampling of Drinking Water
in Schools initiative, visit waterboards.ca.gov/
drinking_water/certlic/drinkingwater/
leadsamplinginschools.shtml.

FLUORIDE
To prevent tooth decay, fluoride is added to your drinking water.

This is a long-standing practice that has improved public health over many years. To read about fluoridation, visit waterboards.ca.gov/drinking_water/certlic/drinkingwater/ Fluoridation.shtml.

CRYPTOSPORIDIUM
Cryptosporidium is a microbial pathogen found in surface water throughout the U.S. Although filtration removes Cryptosporidium, the most commonly-used filtration methods cannot guarantee 100 percent removal. Our monitoring indicates the presence of these organisms in our source water and/or finished water.

Current test methods do not allow us to determine if the organisms are dead or if they are capable of causing disease.

Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy individuals can overcome the disease within a few weeks. However,
immunocompromised people, infants and small children, and the elderly are at greater risk of developing life-threatening illness.

We encourage immuno-compromised individuals to consult
their doctor regarding appropriate precautions to take to avoid infection. Cryptosporidium must be ingested to cause disease, and it may be spread through means other than drinking water.

Although it may appear to be wasteful, flushing
of hydrants is an important maintenance
practice for our water system and allows
us to deliver the highest quality water
to our customers. Flushing removes
mineral and sediment deposits
that build up over time in our
underground system of pipes.

While the buildup is not
harmful to customers, it
can create taste and
odor issues if not
flushed out.

THE SOURCE OF YOUR WATER
Nearly every drop of water delivered by Contra Costa Water District (CCWD) originates in the Sacramento-San Joaquin River Delta. Though Delta water quality fluctuates throughout the year, investments made by your water provider ensures the water delivered to your tap is of a consistent high-quality. Contra Costa Water District diverts water from four locations in the Delta and adjusts its operations to divert where water quality is best.

CONTRA COSTA WATER DISTRICT
CCWD provides treated drinking water to homes and businesses in Clayton, Clyde, Concord, Pacheco, Port Costa, and parts of Martinez, Pleasant Hill and Walnut Creek. Water is pumped from the Delta, treated and then delivered to customers through a network of distribution pipes.

In June 2002 and May 2003, source water assessments were conducted at the Old River, Rock Slough and Mallard Slough intakes, the Los Vaqueros, Contra Loma, Mallard and Martinez reservoirs, and the Contra Costa Canal at Clyde. A source water assessment was conducted for the Middle River Intake in 2012.

The assessments were based on a review of data collected from 1996 through 2001, as well as a review of the activities and facilities located at or near each source. In summary:
• Intakes were found to be most vulnerable to the effects of saltwater intrusion, agricultural drainage, recreational boating and regulated point discharges.
• Reservoirs were found to be most vulnerable to the effects of associated recreation, roads and parking lots, and watershed runoff. • Contra Costa Canal was found to be most vulnerable to gas stations, chemical/petroleum processing/storage, septic systems, historic landfills and military institutions.

CCWD completes watershed sanitary surveys every five years and the last one was completed in 2015. The surveys concluded that potential contamination is regularly mitigated by the natural flushing of the Delta, controls at contamination sources and existing water treatment practices.

BAY POINT
The Golden State Water Company (GSWC) purchases treated water from CCWD and delivers it to customers through its distribution pipes. Water quality information for GSWC is not included in this report. View its water quality report at gswater.com/baypointccr.

BRENTWOOD
CCWD operates the CCWD/City of Brentwood’s water treatment plant to treat water for the City. Water quality information for Brentwood is not included in this report. View its water quality report at brentwoodca.gov/gov/pw/water/reports.asp.

MANAGING WATER THROUGH EMERGENCIES

DELIVERING ON PROMISES DURING POWER SHUTOFFS
While hundreds of thousands of Californians went days without power in 2019 during Pacific Gas and Electric’s pre-emptive power shutoffs, water users in central and eastern Contra Costa County were able to depend on Contra Costa Water District to keep the water flowing.

Water agencies are heavily dependent on power to pump, treat, and distribute water for homes, businesses, and firefighting. In 2019, as Public Safety Power Shutoffs threatened or hit regions of our service area, our early preparations ensured not a single customer’s water service was impacted while our power was out.

HERE’S HOW WE’RE PREPARED
Standby Power – We’ve invested heavily in onsite generators at our major facilities. In the face of power shutoffs, we proactively rented additional generators and staged and fueled them in critical locations throughout our system.

Full Reservoirs – Large holding tanks hidden throughout the community use gravity to push water to nearby homes and businesses but require electricity to pump full of water. Ahead of announced power shutoffs, we filled these reservoirs to capacity to maximize available water.

Communication – We notified customers about the risks and let them know what actions they could take to best prepare for a power shutoff event. We coordinated our response across agencies to optimize resources and maximize reliability.

We expect Public Safety Power Shutoffs to emerge again in 2020 and beyond. Get preparedness tips at ccwater.com/1040/.

RESPONDING TO COVID-19 IN OUR COMMUNITY
Following the first cases of COVID-19 in our region, Contra Costa Water District swiftly adjusted its operations to ensure continuity of high-quality water service for its customers. Water quality was not a challenge during this outbreak— existing filtration and disinfection processes remove and kill viruses including COVID-19.

As an essential service, our field crews worked shifts around the clock to increase social distancing while ensuring we could respond to breaks and other water-emergencies. We closed buildings to the public and cancelled or postponed non-essential meetings, workshops, and tours.

Given the hardships this emergency placed on our customers, Contra Costa Water District suspended water shutoffs due to nonpayment during the outbreak.

We are proud to be your water provider and take pride in delivering safe, high-quality water—even during emergencies.

Backup generators would keep our water treatment plants running during an emergency.

CITY OF ANTIOCH

SOURCE OF WATER
The City of Antioch
purchases untreated water
from CCWD, treats it in
a City-owned treatment
plant and delivers it to
customers through the
City’s distribution pipes.

The City is also able to
pump directly from the San
Joaquin River or purchase
treated water from CCWD.

In April 2003, Antioch
conducted a source water
assessment. In summary:
• Antioch Municipal
Reservoir was found
to be most vulnerable
to sewer collection
systems; this activity
is not associated with
contaminants in the
water supply.
• San Joaquin River
was found to be most
vulnerable to the effects
of saltwater intrusion,
chemical/petroleum
processing or storage,
and regulated point
discharges.

Water from the San
Joaquin River is not
always acceptable due to
saltwater intrusion. When
chloride levels in the river
exceed 250 milligrams
per liter, the City stops
pumping until chloride
levels decrease.

The City completes
watershed sanitary surveys
every five years. The last
survey, completed in 2018,
concluded that potential
contamination is regularly
mitigated by the natural
flushing of the Delta,
controls at contamination
sources and existing water
treatment practices.

a City-owned treatment
plant and delivers it to
customers through the
City’s distribution pipes.

In addition to the water it
buys from CCWD, the City
is able to pump water from

A source water assessment
was conducted for the
Dover Well in September
2015, and for Bodega Well
in July 2009. In summary:
• Bodega well was found
to be most vulnerable
to residential sewer
collection systems,
abandoned military
installation (Camp
Stoneman) and illegal
activities (drug labs).
• Dover well was
considered most
vulnerable to sewer
collection systems,
transportation corridors,
and storm drain
discharge points. No
contaminants associated
with the identified
potentially contaminating
activities (PCA) have
been detected in water
samples from Dover well.

SOURCE OF WATER
Diablo Water District
purchases untreated
water from CCWD. Water is
treated and blended with
groundwater pumped from
two wells. The treated
water is then delivered
to customers through its
distributions pipes.

A source water assessment
was conducted for the
Glen Park well in April 2005
and for Stonecreek well in
March 2011. In summary:
• Both wells were found
to be most vulnerable to
historic waste dumps/
landfills and septic
systems (high density,

CONTAMINANTS THAT MAY BE PRESENT IN SOURCE
WATER
Microbial contaminants include viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Pesticides and herbicides may come from a variety of sources, such as agriculture, urban stormwater runoff and residential uses.

Radioactive contaminants can be naturally occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, the U.S.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some
contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the US EPA’s Safe Drinking Water Hotline (1-800-426-4791).

IMPORTANT NOTICE
Some people may be more
vulnerable to contaminants
in drinking water than the
general population. Immunocompromised persons such as
persons with cancer undergoing
chemotherapy, persons who have
undergone organ transplants,
people with HIV/AIDS or other
immune system disorders,
some elderly, and infants can be
particularly at risk from infections.

These people should seek advice
about drinking water from their
health care providers. USEPA/
Centers for Disease Control (CDC)
guidelines on appropriate means
to lessen the risk of infection
by Cryptosporidium and other
microbial contaminants are
available from the Safe Drinking
Water Hotline at 1-800-426-4791.

Your drinking water is continually sampled and analyzed. We perform tens of thousands of tests throughout the year to ensure your water is clean and safe to use. 584
Sedimentation basins in
our water treatment
plants skim clean water
from the top of the basin
and allow heavy
organics to settle out
at the bottom.
2020 ANNUAL WATER QUALITY REPORT 3

WATER QUALITY NOTIFICATIONS

LEAD MONITORING IN SCHOOLS
In early 2017, the State Board issued amendments to domestic water supply permits of community water systems so that kindergarten through 12th grade (K–12) schools can request assistance from their water provider to conduct water sampling for lead and receive technical assistance if an elevated lead sample is found. To further safeguard water quality in California’s K–12 public schools, California Assembly Bill 746, effective January 1, 2018, requires community water systems to test lead levels, by July 1, 2019, in drinking water at all California public K–12 schools, preschools, and child care facilities located on public school property constructed before January 1, 2010.

Your water providers are currently assisting local schools in our service area. Please see the tables on 7–11 to find out how many schools requested sampling in 2020. To find out more about the Lead Sampling of Drinking Water in Schools initiative, visit waterboards.ca.gov/drinking_water/certlic/drinkingwater/ leadsamplinginschools.shtml.

FLUORIDE
To prevent tooth decay, fluoride is added to your drinking water.

This is a long-standing practice that has improved public health over many years. To read about fluoridation, visit waterboards.ca.gov/drinking_water/certlic/drinkingwater/ Fluoridation.shtml.

Current test methods do not allow us to determine if the organisms are dead or if they are capable of causing disease.

The use of ozone disinfection
results in drinking water that
is very safe, with little taste
and odor. Ozone effectively
destroys potentially harmful
microorganisms and, by
breaking up the organic
material often found in water,
vastly improves the taste and
odor of drinking water. In
addition, ozone disinfection
reduces the formation of many
disinfection byproducts, such
as trihalomethanes, a class
of suspected cancer-causing
compounds associated with
chlorine disinfection.

THE SOURCE OF YOUR WATER
Nearly every drop of water delivered by Contra Costa Water District originates in the Sacramento-San Joaquin River Delta.

Though Delta water quality fluctuates throughout the year, investments made by your water provider ensures the water delivered to your tap is of a consistent high-quality. Contra Costa Water District diverts water from four locations in the Delta and adjusts its operations to divert where water quality is best.

YOUR WATER IS SAFE AND RELIABLE

INVESTMENTS IN

INFRASTRUCTURE
We’ve recently replaced the
concrete liner along several
sections the 48-mile Contra Costa
Canal. The Contra Costa Canal is the
backbone of our water system, delivering
water to treatment plants, businesses, and
agriculture.

In addition to ensuring safe, clean water at your
tap, it’s our responsibility to maintain and upgrade the facilities that move the water throughout our communities.

Every year, we invest in infrastructure upgrades like pipeline replacement, Contra Costa Canal rehabilitation, storage tank improvements, and much more to avoid costly and disruptive breaks in our system.

To learn more about planned capital improvements, visit ccwater.com/ ArchiveCenter/ViewFile/Item/323

THE FACTS ABOUT PFAS
PFAS—short for per- and polyfluoroalkyl substances—are a group of man-made chemicals that includes PFOA, PFOS and GenX chemicals. Since the 1940s, PFAS have been manufactured and used in a variety of industries around the globe, including in the United States. The chemicals have been used in consumer products such as carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) designed to be waterproof, stain-resistant, or non-stick. They also have been used in fire-retarding foam at airfields, military bases, and various industrial processes. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both are very persistent in the environment and in the human body. Exposure to certain PFAS can lead to adverse human health effects. Unfortunately, some of these substances don’t break down over time. That means they build up in the environment and in our bodies.

Testing has confirmed that CCWD’s water supply is safe to drink and PFOA/PFOS were not detected during monitoring in 2013.

To learn more about PFAS and drinking water, visit ccwater.com/422.

SAFE FROM COVID-19
Existing filtration and disinfection processes in our water treatment systems remove and kill viruses including the coronavirus. While water quality was unaffected by this new virus in our community, operations were adjusted to ensure the skilled workforce that treats, operates, and maintains remained healthy and able to keep your public water system functioning.

Coronavirus does not post a threat to the water you depend on for drinking, bathing, washing, and so much more.

Additional information about coronavirus and drinking water is available at epa.gov/coronavirus/coronavirus-and-drinking-water-and-wastewater. 587

CONTAMINANTS THAT MAY BE PRESENT

IN SOURCE WATER
Microbial contaminants include viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Pesticides and herbicides may come from a variety of sources, such as agriculture, urban stormwater runoff and residential uses.

Radioactive contaminants can be naturally occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, the U.S.

WATER QUALITY NOTIFICATIONS

LEAD MONITORING IN SCHOOLS
In early 2017, the State Board issued amendments to domestic water supply permits of community water systems so that kindergarten through 12th grade (K–12) schools can request assistance from their water provider to conduct water sampling for lead and receive technical assistance if an elevated lead sample is found. To further safeguard water quality in California’s K–12 public schools, California Assembly Bill 746, effective January 1, 2018, requires community water systems to test lead levels, by July 1, 2019, in drinking water at all California public K–12 schools, preschools, and child care facilities located on public school property constructed before January 1, 2010.

To find out more about the Lead Sampling of Drinking Water in Schools initiative, visit waterboards.ca.gov/drinking_water/ certlic/drinkingwater/leadsamplinginschools.shtml.

FLUORIDE
To prevent tooth decay, fluoride is added to your drinking water.

This is a long-standing practice that has improved public health over many years. To read about fluoridation, visit waterboards.ca.gov/drinking_water/certlic/drinkingwater/ Fluoridation.shtml.

CRYPTOSPORIDIUM
Cryptosporidium is a microbial pathogen
found in surface water throughout the U.S.

Although filtration removes Cryptosporidium, the
most commonly-used filtration methods cannot
guarantee 100 percent removal. Our monitoring
indicates the presence of these organisms in our source water and/or finished water. Current test methods do not allow us to determine if the organisms are dead or if they are capable of causing disease. Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps.

Most healthy individuals can overcome the disease within a few weeks. However, immunocompromised people, infants and
small children, and the elderly are at greater risk of developing life-threatening illness. We encourage immuno-compromised individuals to consult their doctor regarding appropriate precautions to take to avoid infection. Cryptosporidium must be ingested to cause disease, and it may be spread through means other than drinking water.

Your drinking water is continually sampled and analyzed. We perform tens of thousands of tests throughout the year to ensure your water is clean and safe to use.

Reservoirs
strategically
placed in high
points throughout
our service areas store
millions of gallons of
treated water that is used
by homes, businesses and
firefighters!
Skilled operators use sophisticated technology to control the systems that treat your drinking water and move it to reach the 500,000 people who depend on it every day.

THE SOURCE OF YOUR WATER
Nearly every drop of water delivered by Contra Costa Water District originates in the Sacramento-San Joaquin River Delta.

CCWD completes watershed sanitary surveys every five years and the last one was completed in 2021. The surveys concluded that potential contamination is regularly mitigated by the natural flushing of the Delta, controls at contamination sources and existing water treatment practices.

YOUR WATER IS SAFE AND RELIABLE

DELIVERING

DURING A DROUGHT

EMERGENCY
Like most of the state, the effects
of three consecutive dry years
are straining local water supplies.

Snowmelt that typically filled rivers and
reservoirs instead soaked into the parched
earth. Indeed, the first three months of 2022
were some of the driest on record since 1920. The
Central Valley Project, which supplies water to Contra
Costa Water District, will deliver just a fraction of our usual allocation.

Thanks to our customers’ wise investment in Los Vaqueros Reservoir and their strong commitment to using water efficiently, local water storage levels mean we have sufficient supply this year to meet the efficient water needs of our customers. However, we still need your help eliminating wasteful water uses, reducing discretionary water uses, and getting the most value out of every drop.

MONITOR YOUR USE
One of the best ways to reduce your water use and help sustain our community through this drought is to know when and where you are using water. If you know when and where you are using water, you will have an easier time making small changes that add up to big savings! While each water provider offers unique ways for customers to track use, everyone can track their water use by regularly reading their own water meter. Additionally, for a small cost, customers can install a smart home water monitor to get real time usage statistics and leak alerts!
TIPS TO #CONSERVEINCONTRACOSTA
Learn how to save water and share your own tips with the hashtag #ConserveinContraCosta! To spread water-saving tips, Contra Costa Water District is producing a series of videos called Conserving in Contra Costa. These short and informative videos provide practical tips that you can quickly and easily put into practice.

View these videos and learn more about the rebates, resources, services available during this drought at ccwater. com/drought
Questions about this drought and what you can do to help? Contact your water provider using the phone numbers on the cover of this report.

SAFE FROM COVID-19
Existing filtration and disinfection processes in our water treatment systems remove and kill viruses including the coronavirus. While water quality was unaffected by this new virus in our community, operations were adjusted to ensure the skilled workforce that treats, operates, and maintains your water remained healthy and able to keep your public water system functioning. Coronavirus does not pose a threat to the water you depend on for drinking, bathing, washing, and so much more.

Additional information about coronavirus and drinking water is available at epa.gov/coronavirus/coronavirus-and-drinking-water-and-wastewater.

OFFICE OF THE CITY MANAGER/EXECUTIVE DIRECTOR
65 Civic Avenue
Pittsburg, CA 94565
TO: Mayor/Chair and Council/Governing Board Members
FROM: Garrett Evans, Executive Director/City Manager
SUBJECT: Adoption of a City Council Resolution to Amend Water Rates MEETING DATE: July 18, 2022

EXECUTIVE SUMMARY
On May 16, 2022, the following was presented: In 2018, the City Council adopted a multiyear water rate increase through 2021. Since that time, the City’s costs for raw water, energy, and other related costs have risen. In addition, the City has prioritized approximately $76.5 million in capital improvements to the Water Treatment Plant and system infrastructure needed to maintain or improve water quality and reliability of the supply to customers. For these reasons, staff recommends a schedule of cost increases for residential and commercial water customers of 5% per year over the next five fiscal years.

Rates for the Senior customer class are increased at 2% per year over that same period.

FISCAL IMPACT
Proposed increases for adoption by the City Council will help meet the financial requirements of the Water Fund for annual operations and maintenance. Water rate increases of 5% per year for the next five years are projected to raise approximately $19.6 million cumulative additional revenue for the Water Fund during that time period. A forecast for water revenues and expenses is attached to the report as part of the Municipal Financial Services Water Rate Study.

RECOMMENDATION
On May 16, 2022, City Council opened the public hearing and authorized the publication of Proposition 218 Notice and kept the hearing open for continued comments through the July 18, 2022, meeting. At tonight’s meeting, the City Council will continue to take public comment and consider adoption of the attached resolution to amend water rates. 602

BACKGROUND
In 2018, the City Council adopted rates for calendar years 2018 through 2021 in accordance with provisions of Proposition 218. The last rate increase took effect on January 1, 2021.

Staff evaluated increases in operational costs for the City’s Water utility and proposes an average increase to monthly water service charges and water quantity rates of 5% per year starting August 1, 2022 and continuing 5% increases on January 1st of 2024, 2025, 2026, and 2027.

A Proposition 218 Notice of Public Hearing (“Notice”) was sent in late May 2022 to all ratepayers and parcel owners in the City. This timing complies with the required minimum 45-day noticing period between the distribution of the Notice and the July 18th public hearing.

In addition to the physical, printed Notice, an electronic copy of the Notice was posted on the City’s website in Chinese, English, Korean, Spanish, Tagalog, and Vietnamese.

SUBCOMMITTEE FINDINGS
A discussion of the underlying capital needs and assumptions behind the rate study has been presented to the Finance Subcommittee on January 21, 2022, and February 4, 2022.

Additionally, a discussion was presented to the City Council on March 7, 2022, and May 16, 2022.

Finance Subcommittee supported staff’s recommendation to increase the water rates as presented in this report and attached supporting documentation.

STAFF ANALYSIS
In 2021, City engaged the services of an outside consultant (Municipal Financial Services) to prepare a Water Utility Rate Study (“Rate Study”) and make recommendations about future water rates for residents and commercial businesses in the City. Based upon the findings of the study, including increasing raw water costs, increasing operational costs, and current infrastructure needs, staff recommends the City increase water rates to cover increased operational costs and for repair and replacement of operational assets.

The Rate Study evaluates the increases in rates needed to provide for increasing operational costs and approximately $76.5 million in needed capital improvements over the next five years. The City recently issued water revenue bonds to fund $45.8 million of those capital improvements and water rates will be supporting the annual debt service on those bonds. In addition to the bonds, the City expects to utilize pay-as-you go cash funding to cover the other $30.7 million over the next 6 years (approximately $5 million per year).

Pursuant to the provisions of Proposition 218 and Proposition 218 Omnibus Implementation Act of 1997, the City is required to provide notice and protest procedures to ratepayers and/or property owners in order to approve increased water rates. 603
City staff distributed a printed version of the Notice for the water rate increases following City Council’s May 16, 2022, approval of a resolution adopting guidelines for the rate increase protest process. The Notice was sent in late May 2022, at least 45 days prior to the July 18, 2022, public hearing. In addition to the physical, printed Notice, an electronic copy of the Notice was posted on the City’s website in Chinese, English, Korean, Spanish, Tagalog, and Vietnamese.

The City Clerk would need to receive written protests equivalent to a majority of ratepayers/property owners. For the purposes of Proposition 218, a majority is defined as 50% + 1. The City serves approximately 18,710 accounts and the City would need to receive over 9,355 written protests for a majority protest. As of the writing of this report, the City has received under 400 written protests from water customers.

The City Clerk has maintained a tabulation of the number of protests and the final number of protests (including protests received during the July 18 meeting) will be provided to the City Council.

The Resolution for this item identifies the proposed rate increases over the next five fiscal years – beginning with 5% on August 1, 2022, followed by additional rate increases of 5% on January 1st of 2024, 2025, 2026, and 2027. Over this same period, rates for the Senior customer class will be increased at 2% per year. These increases will apply to the water quantity rates, as well as the monthly meter service charges.

As detailed in the Rate Study, through fiscal year 2026-27, the Water Fund will require cumulative revenues of approximately $206.6 million in order to meet the projected operating expenses of the Water Fund and capital improvement project needs. The rate increase schedule is expected to provide approximately $19.6 million in cumulative additional revenues. Total Water Fund expenses are projected to be approximately $212 million over that same period. Accordingly, the Water Fund will draw down cash balance by approximately $5.7 million over the next five fiscal years to cover needed capital and operational costs.

CITY OF PITTSBURG
Notice of Public Hearing on Proposed Water Rate Increases Monday, July 18, 2022, at 7:00 p.m.

Council Chambers – 65 Civic Avenue, Pittsburg, CA 94565 Public Hearing
The City of Pittsburg wishes to notify you of a Public Hearing of the City Council on July 18, 2022, at 7:00 p.m. at the City Hall Council Chambers to discuss Water rate increases for fiscal years (FY) 2022/23 through 2026/27. The City will accept public comments at the Public Hearing. The City Council may increase water rates at the end of the hearing.

The meeting room is accessible to the disabled. Persons with hearing or vision disabilities may ask before the meeting for assistance in participating in the meeting.

Protests
Any water customer or owner of a property served by the City water utility may submit a written protest to the City by:
 Hand delivering it during business hours or mailing it to the City Clerk, 65 Civic Avenue, Pittsburg, CA 94565; or
 Personally submitting the protest at the Public Hearing.

Protests must be received by the end of the public hearing, including those mailed to the City. Protests not actually received by the end of the hearing (whether or not mailed before the hearing) will not be counted. Only one protest will be counted per parcel even if both an owner and a tenant protest, for example. Protests will not be counted it they are emailed or faxed to the City, and they must have an original signature on them. Although oral comments at the public hearing will not count as a protest unless a written protest is also submitted, the City Council welcomes input from the community on the proposed water rates. A written protest must include the following, and will not be counted if any of these required elements is omitted: a statement protesting the proposed water rate increase; name of the water customer or property owner who is submitting the protest; identity, by street address or Assessor’s Parcel Number, of the parcel for which the protest is submitted; original signature and legibly printed name of the customer or property owner who is submitting the protest.

Additionally, there is a 120-day deadline for a lawsuit challenging the water rate increases under Government Code section 53759(d).

Need for Rate Increases
The proposed increases are needed to maintain the water utility’s finances and physical assets, and to address new Federal and State requirements for water service, as well as increasing costs of water service. Water rates must cover the cost to operate and maintain expenses (including labor, utilities, and supplies), capital expenditures for pipes, tanks and other water system assets, and adequate reserves. This rate increase is necessary due to rising costs of raw water and water treatment as well as maintaining water tanks and pipes and by new Federal and State requirements. The City is committed to improving and maintaining our aging water assets while providing excellent services. City staff recommends annual rate increases to make that possible.

Water Rates - Proposed Rate Structure (Tables 1 and 2): The water rates have three parts: 1) a monthly service charge which varies by water meter size: 2) a rate for metered water use, and 3) fee per connection for water lines to serve fire sprinklers. Use rates are higher for customers in higher elevations the city because of electricity costs to pump water up to those properties. Most single-family customers have a ⅝- or ¾-inch meter. Charges for water use have two or three prices. The first rate applies to use of 12 hundred cubic feet (HCF) of water or less per month for 609
customers in single-family properties; the second rate applies for water used above that amount in a month. A uniform rate applies to all other customers except seniors. Use rates for seniors have three tiers and are lower than other resident rates. All proposed rates, including single-family, non-single-family and senior rates, appear in Tables 1 and

2. The proposed rates will increase rates each year for five years.

If approved, the new rates will go into effect on August 1, 2022.

For further information, please contact Paul Rodrigues, Finance Director at [email protected] or at (925) 252-4848.

CIUDAD DE PITTSBURG
Aviso de audiencia pública sobre los aumentos propuestos en las tarifas de agua Lunes, 18 de julio de 2022, a las 7.00 p.m.

Cámaras del Consejo – 65 Civic Avenue, Pittsburg, CA 94565 Audiencia Pública
La ciudad de Pittsburg desea notificarle sobre una audiencia pública del Concejo Municipal el 18 de julio de 2022 a las 7:00 p.m. en las Cámaras del Consejo Municipal para discutir los aumentos en las tarifas de agua para los años fiscales (FY) 2022/23 a 2026/27. La Ciudad aceptará comentarios públicos en la audiencia pública. El Consejo Municipal puede aumentar las tarifas de agua al final de la audiencia. La sala de reuniones es accesible para personas con discapacidades. Las personas con discapacidades auditivas o visuales pueden solicitar asistencia para participar antes de la reunión.

Protestas
Cualquier cliente de agua o propietario de una propiedad servida por el servicio público de agua de la Ciudad puede presentar una protesta por escrito a la Ciudad:
 Entregándola personalmente durante el horario comercial o enviándola por correo a City Clerk, 65 Civic Avenue, Pittsburg, CA 94565; o
 Presentando personalmente la protesta en la audiencia pública.

Las protestas deben recibirse al final de la audiencia pública, incluidas las que se envían por correo a la Ciudad. Las protestas que no se hayan recibido al final de la audiencia (independientemente de si se enviaron por correo antes de la audiencia o no) no serán contadas. Solo se contará una protesta por parcela, incluso si protestan tanto el propietario como el inquilino, por ejemplo. Las protestas no serán contadas si se envían por correo electrónico o por fax a la Ciudad y deben contener una firma original. Aunque los comentarios orales en la audiencia pública no contarán como una protesta a menos que también se presente una protesta por escrito, el Consejo Municipal agradece los aportes de la comunidad sobre las tarifas de agua propuestas. Una protesta por escrito debe incluir lo siguiente, y no se contará si se omite alguno de estos elementos requeridos: una declaración de protesta por el aumento propuesto en la tarifa del agua; nombre del cliente de agua o dueño de la propiedad que presenta la protesta; identidad, por dirección postal o Número de Parcela del Tasador, de la parcela por la cual se presenta la protesta; firma original y nombre legiblemente impreso del cliente o dueño de la propiedad que presenta la protesta.

Además, hay un plazo de 120 días para presentar una demanda judicial que desafíe los aumentos de las tarifas del agua según la sección 53759(d) del Código de Gobierno.

Necesidad del aumento de tarifas
Los aumentos propuestos son necesarios para mantener las finanzas y los activos físicos de la empresa de agua, y para abordar los nuevos requisitos federales y estatales para el servicio de agua, así como el aumento de los costos del servicio de agua. Las tarifas de agua deben cubrir el costo de operar y mantener los gastos (incluyendo mano de obra, servicios públicos y suministros), gastos de capital para tuberías, tanques y otros activos del sistema de agua, y reservas adecuadas. Este aumento de las tarifas es necesario debido al aumento de los costos del agua sin tratar y el tratamiento del agua, así como del mantenimiento de los tanques y tuberías de agua, y por los nuevos requisitos federales y estatales. La Ciudad está comprometida a mejorar y mantener nuestros activos de agua envejecidos mientras brinda excelentes servicios. El personal de la ciudad recomienda aumentos de tarifas anuales para que eso sea posible.
611
Tarifas de agua - Estructura de tarifas propuesta (Tablas 1 y 2): Las tarifas de agua tienen tres partes: 1) un cargo por servicio mensual que varía según el tamaño del medidor de agua: 2) una tarifa por el uso de agua medido y 3) una tarifa por conexión para las líneas de agua que sirven a los rociadores contra incendios. Las tarifas de uso son más altas para los clientes en elevaciones más altas de la ciudad debido a los costos de electricidad para bombear agua hasta esas propiedades. La mayoría de los clientes unifamiliares tienen un medidor de ⅝ o ¾ de pulgada. Los cargos por uso de agua tienen dos o tres precios. La primera tarifa se aplica al uso de 1200 pies cúbicos (hundred cubic feet, HCF) de agua o menos por mes para clientes en propiedades unifamiliares; la segunda tarifa se aplica al agua utilizada por encima de esa cantidad en un mes. Se aplica una tarifa uniforme a todos los demás clientes, excepto a las personas de la tercera edad. Las tarifas de uso para personas de la tercera edad tienen tres niveles y son más bajas que otras tarifas para residentes. Todas las tarifas propuestas, incluidas las tarifas unifamiliares, no unifamiliares y para personas de la tercera edad, aparecen en las Tablas 1 y 2. Las tarifas propuestas aumentarán las tarifas cada año durante cinco años.

Si son aprobadas, las nuevas tarifas entrarán en vigor el 1 de agosto de 2022.

Executive Summary
The City of Pittsburg, in conjunction with Municipal Financial Services, has analyzed the adequacy of revenues from rates to meet projected expenditures of the water enterprise fund to determine whether revenues will be adequate to cover operating and maintenance costs as well as needed capital costs while meeting reserve policy and debt management policy. Water rates and charges were developed for the five-year period Fiscal Year 2022–23 (FY23) through FY27.

Water Fund 501 Revenues, Expenditures and Cash Balances Water rates were developed to generate sufficient revenues to cover operating and maintenance expenditures, fund capital expenditures, satisfy debt service coverage requirements and meet target reserve levels. A summary of the projected expenditures, revenues, beginning (FY23) and ending (FY27) fund balances, and the FY27 target reserve amount are shown in the table below.

The approximate amount of
revenues required from water
rates for the period, FY23 through
FY27, is $156,000,000.

Projected operations and
transfers funding requirements
are approximately $124,100,000
(58 percent of expenditures).

Projected capital expenditure
funding requirements are
approximately $63,300,000 (30
percent of expenditures).

Projected debt service funding
(principal and interest payments)
requirements are approximately
$24,960,000 (12 percent of
expenditures).

Debt service coverage
requirements are met in all years.

Recommended Water Rates
In 2018, cost-of-service rates were developed using a rate structure that is consistent with the requirements of Proposition 2181 as codified in the State of California Constitution, Articles XIIIC and XIIID, which require that each customer class pay its proportionate share of the required revenue in proportion to their beneficial use of the water system. The City adjusted the cost-of-service rates so that changes in the rates were phased-in. Recommended rates for FY23 – FY27 are based on “across-theboard” increases” to the FY21 rates adopted in 2018 and the break between Tier 1 and Tier 2 Single Family water use is lowered from 13 HCF to 12 HCF.

FY22 (current) and recommended Water Quantity rates for FY23 – FY27 are listed in the table below.

Rates for all services (except Senior customer classes) are increased at approximately 5 percent per year. Rates for the Senior customer class are increased at approximately 2 percent per year.

Table ES-1. Current and Recommended Water Quantity Rates 1 Article XIIIC and Article XIIID were added to the California Constitution in 1996 by Proposition 218, the Right to Vote on Taxes Act. Article XIIID, Section 6(b) lists the five substantive requirements for "property related fees and charges." Current Recommended

Water Rates Study Executive Summary
ES-3
DRAFT for review purposes only. Use of contents on this sheet is subject to the limitations specified at the end of this document.

For Meter Service cost-of-service rates adopted in 2018, costs associated with meter size are allocated based on the California Public Utilities Commission Water Division, "Rate Design for Water and Sewer System Utilities Including Master Metered Facilities", July 2006 (Standard Practice U-7-W).

For Fire Line Service cost-of-service rates adopted in 2018, costs are allocated based on demand factors based on the nominal connection size as explained in the American Water Works Association (AWWA) Manual of Water Supply Practices M1 Principles of Water Rates, Fees and Charges. Residential customers with water meters increased to 1-inch to accommodate a combined domestic-fire sprinkler system are charged the ¾-inch meter charge.

The City adjusted the 2018 cost-of-service rates so that changes in the rates were phased-in. The phased-in cost-of-service rates for 2-inch and smaller and 3-inch Fire Line Services are maintained for FY23 – FY27. Other recommended rates are based on “across-the-board” increases” to the FY21 rates adopted in 2018.

FY22 (current) and recommended Meter Service and Fire Line Service rates for FY23 – FY27 are listed in the table below. Rates for all services (except Senior customer classes and the two categories of Fire Line Services) are increased at approximately 5 percent per year. Rates for the Senior customer class are increased at 2 percent per year.

Table ES-2. Current and Recommended Meter Service and Fire Line Service Rates City of Pittsburg Resolution 17-13400 established new Municipal rates for the City of Pittsburg’s water consumption and meter charges at 35% of the non-residential rates. The City intends to keep Municipal rates at 35% of the non-residential rates. Quantity and meter service rates for Municipal connections are not listed in the tables above but may be derived from the non-residential quantity rates and meter service rates shown in the tables.

Section 1
Introduction
This section describes the organization of the report, rate-making objectives, the rate-setting process, and a general description of the water system.

1.1 Organization of the Report
This report is divided into six sections. This introduction provides an overview of the study objectives and an overview of the rate development process.

Section 2 discusses characteristics of customers and their use of the water system. The number and type of connections to the system and water use projected for FY22 – FY27 is developed in this section.

Section 3 describes the evaluation of revenue required from rates.

Section 4 describes the development of water rates.

Section 5 describes the impact of rates changes on customer bills.

Section 6 describes the limitations of the study document.

1.2 Rate-Making Objectives
There are numerous rate-making objectives that must be considered when developing rates and rate structures.

Revenue sufficiency. Generate sufficient revenue to fund operating costs, capital costs and bonded debt, and maintain adequate reserves.

Revenue stability. Recover revenue from fixed and variable charges that will cover fixed and variable costs.

Conservation signal. Reward customer for efficient water use and discourage its waste.

Administrative efficiency. Enable efficient implementation and ongoing administration, including monitoring and updating.

Affordability. Be as affordable as possible while maintaining the utilities sound financial position and credit rating.

Customer acceptance. Be as simple as possible to facilitate customer understanding and acceptance.

Fairness. Provide for each customer class to pay its proportionate share of the required revenue in compliance with legal rate-making requirements.

1.3 Overview of Utility Rate Setting Process
Rate studies classically have three categories of technical analysis – the development of revenue required from rates, the allocation of costs among functional cost categories (cost-of-service analysis) and the design of a rate structure. An overview of the rate-setting analytical steps is shown in Figure 1-1.

The revenue required from rates is net of non-rate
revenues (for example interest earned on fund
balances, loan disbursements and revenue from
new connections to the water system) and other
revenues not required from rates (such as revenue
from meter turn on/off services). The allocation of
costs are structured so that the revenue required
from charges is distributed proportionally for every
level of service in a manner that allows the
development of unit costs. The rate structure uses
the unit costs as a basis for aggregating costs into
rates that are applicable to the various customer
classes.

Figure 1-1. Overview of Rate Setting Analytical Steps
Information and data for the development of water rates and preparation of this report comes from several documents provided by the City. The list of documents, and the key information and data from each used in this study, are summarized below.

City of Pittsburg Fiscal Year 2021-22 Adopted Budget and Accounting Reports. This document shows the recommended FY 2021-22 Annual Budget. In addition to the published Budget, the City provided detailed expenditure and revenue data in separate expenditure and revenue reports from its accounting system. The water enterprise fund is funded primarily from user charges.

City of Pittsburg Municipal Code. Ordinances relating to the water enterprise are codified in various sections of Title 13, Division 1, of the Pittsburg Municipal Code listed below:
• 13.04 City Duties and Responsibilities
• 13.08 Water Service Connections
• 13.10 Collection of Contra Costa Water District’s Facilities Reserve Charge • 13.12 Water Rates
• 13.14 Regulations for the Control of Backflow and Cross Connections to the City’s Water System • 13.16 Consumer Deposits – Service Beyond the City
• 13.18 Water Conservation
City of Pittsburg Water System Master Plan. The City’s 2015 Water System Master Plan (2015 WSMP) summarizes the existing distribution system infrastructure, and documents the City’s acceptable design criteria and growth assumptions. The 2015 WSMP also documents the capacity evaluation of the existing system and identifies facility improvements needed to meet the water demand needs of existing users, as well as the needs of planned future developments. Finally, the 2015 WSMP includes a capital improvement program and a cost allocation analysis. It should be noted that the City is currently in the process of updating the 2015 WSMP.

Capital Improvement Program (CIP). The City provided a list of CIP projects planned for Fiscal Years 2021/22 through 2026/27.

Utility Billing System data. Monthly water use data for each of the City’s metered accounts, for the period July 2020 through June 2021, were provided in an Excel file. Each account record had descriptive information of the account’s customer class, meter size and elevation pressure zone.

Policy and Procedures. Policy and procedures relating to the water enterprise are codified in various sections of the Pittsburg Municipal Code and in policies adopted by the City. Policy and procedures relating to the water enterprise are listed below.
• Capital Assets Policy and Procedures
• Debt Management Policy (June 2012)
• Fiscal Sustainability and Reserve Funds (PMC Title 3, Chapter 3.26)

1.4 Water Enterprise Funds
The water enterprise fund accounts for activities that are financed and operated in a manner similar to private business enterprises. The City Council has determined that the costs of providing water services to the public be recovered primarily through user charges.

The Water Utility Fund accounts for the revenues and expenses associated with management, operation, and maintenance of water treatment and distribution system to water customers of the City of Pittsburg.

It also accounts for the maintenance of water plant, distribution reservoirs, and water lines.

The city has 12 funds in the water enterprise. The purpose of each fund is summarized below.

Fund 500: Water Revenue Bond Proceeds
Fund 501: Water Operations
Funds 502, 503, 505, 506, 507 and 509 - 511 (eight funds): Water Facility Reserves for various asset groups
Revenue from water charges are accrued in Fund 501. This study models cash flow in Fund 501 only.

Cash flow in funds for Water Facility Reserves ensure that Water Facility Reserve Charges are allocated to the appropriate asset group.

1.5 Pittsburg Water Utility
The City of Pittsburg provides potable water service to approximately 19,200 residential, commercial, industrial, and institutional accounts.

The City of Pittsburg is located on the eastern side of California’s San Francisco Bay in Contra Costa County. It is bound on the north by the Suisun Bay, the City of Antioch on the east, and is surrounded by undeveloped hills to the south and the Concord Naval Weapons Station on the west. The area included in this study is outlined by the City of Pittsburg Urban Limit Line (ULL). The City currently provides domestic water service to the currently developed areas within the ULL and plans to provide service to the anticipated growth areas when they become developed. Water service to Bay Point, in the northwest, and other unincorporated areas is provided by California Cities Water Company, who also receive their water from the Contra Costa Water District.

The City’s municipal water system consists of a water treatment facility, groundwater wells, storage reservoirs, pump stations, over 238 miles of domestic water transmission and distribution mains, in addition to fire hydrants, and pressure reducing valves.

The City’s service area is currently divided into five existing pressure zones servicing elevations from sea level in Zone 1 to 510 feet in Zone 4 West and will eventually be expanded to twelve pressure zones to service anticipated future developments in the southeast and southwest hills. The existing pressure zones are interconnected and include 8 storage reservoirs and 7 booster stations. In addition, 5 major PRVs provide increased supply reliability for Zone 1.

The City has two sources of supply: surface water from the Contra Costa Canal, and groundwater extracted from two active wells in the central part of the City. Water from both sources is conveyed to the City’s water treatment plant where it is first treated, and then conveyed to the distribution system.

1.6 Current Water Rates
Water rates are established per Title 13 (Waters and Sewers), Division I (Water Regulations) of the Pittsburg Municipal Code (PMC). Water rates were last increased on January 1, 2021. The City’s current water use (quantity) rates, water meter service rates and fire line service rates and are shown in the sidebar. The water accounts are billed monthly.

Table 1-1. Current Water Rates
Each water account has one or more meters and each meter is billed for metered water use at the rates shown (except fire service accounts which are not billed for water use).

Qualifying senior citizens are eligible for reduced water rates per a special exemption provision in PMC Section 13.12.035. The quantity rate for first tier 0 – 4 HCF of water use for Senior customers was designated by the City as 40 percent of the Single Family first tier rate.

Residential customers with water meters increased to 1-inch to accommodate a combined domestic-fire sprinkler system are charged the ¾-inch meter charge. Water use by fire line service meters is charged at the nonresidential quantity rate.

City of Pittsburg Resolution 17-13400 established new Municipal rates for the City of Pittsburg’s water consumption and meter charges at 35% of the non-residential rates. The City intends to keep Municipal rates at 35% of the non-residential rates. Quantity and meter service rates for Municipal connections are not listed in the tables above but may be derived from the non-residential quantity rates and meter service rates shown in the tables.

Water delivery projections for FY22 – FY27 are based upon the net impact of two variables: 1) increase in water use due to the growth in the number of metered accounts; and 2) decrease in water use due to conservation. Growth in the number of metered accounts includes approximately 300 single family connections per year. Projected water use for FY22 – FY27 is based on a percent reduction from the previous years’ value. Reductions in metered water use are projected to be 1 percent per year for all customer classes for FY23 and onward. Detailed water delivery is summarized in Table A-2a of Appendix A. Water delivery data for Municipal accounts is summarized in Table A-2b of Appendix A. Projected metered water deliveries, by customer class (including Municipal use), are shown in the figure below.

2.3 Evaluation of Water Use by Block for Single Family Residential Annual average water use is a commonly used as a break point for inclining block rate structures for single family residential accounts. An inclining block rate structure is a schedule of rates applicable to blocks of increasing usage in which the usage in each succeeding (higher usage) block is charged a higher unit rate than in the previous block. In this study, a two-block structure, with the first block including water use equal to or below annual average water use, will be evaluated. Note that the terms “block” and “tier” will be used interchangeably.

Average monthly water use for single family residential accounts for the 12-month period ending June 2021 is shown below in Figure 2-5. Single Family annual average water use for FY21 was approximately

9.6 HCF per month (about 222 gallons per day).

The tier break point for current water rates (13 HCF) was developed in 2018 based on evaluation of historic water use.

Using a first block with water use less than or equal to 13 HCF, water use in each block was calculated for the 12-month period ending June 2021. On an annual basis, the first block, Tier 1, contains approximately 83 percent of all water use. The next block, Tier 2, contains approximately 17 percent of all water use. Water use is shown below in Figure 2-6.

Figure 2-6. Single Family Residential FY21 Tier Water Use, HCF It is recommended the tier break point for water rates be lowered from 13 HCF to 12 HCF. Update of the tier break point is projected to produce the following results: the first block, Tier 1, would contain approximately 80 percent of all water use and Tier 2, would contain approximately 20 percent of all water use. Projected water use using the adjusted tier break is shown below in Figure 2-7.

2.4 Water Meter Equivalency Factors
Meter charges for meter sizes greater than ⅝ x ¾-inch (0.625 inches) are based, in part, on an "equivalency factor" that relates the design maximum flow capacity of a meter (in gallons per minute, gpm) to that of a standard 0.625-inch meter. The water meter service charge ratios (equivalency factors) and maximum flow capacity used in this study are shown in the table below and are based on values published by the California Public Utilities Commission Water Division.

Debt service coverage ratios exceed the minimum ratio of 1.25 in all years. Operating reserves exceed the policy target levels of 30 percent of operating expenses plus 10 percent drought reserves in all years.

3.5 Funds 502 - 511 Available Fund Balances
The City established a series of funds for the purpose of tracking revenue generated from Facility Reserve Charges (FRCs). A facility reserve charge is a charge to pay for public agencies’ facilities in existence at the time the charge is imposed or to pay for new facilities that will be constructed in the future that are of benefit to the person or property being charged (new development or increases to existing service capacity). The FRCs ensures that the “growth pays for growth” by allocating the cost of new facilities and the cost of unused capacity in existing facilities to new development while allocating the cost of repairing and refurbishing facilities used by current customers to rates.

There is a separate fund for each of the various asset groups developed in the study used to calculate FRCs. The amount of cash in each of these funds as of June 30, 2021 is summarized in the table below.

Table 3-4. Available Fund Balances Water Funds 502, 503, 505, 506, 507 and 509 - 511 The City plans to update water FRCs which will include estimates of projected expenditures, revenues, and fund balances for these funds.

Section 4
Water Rates
In 2018, cost-of-service rates were developed using a rate structure that is consistent with the requirements of Proposition 218 as codified in the State of California Constitution.

4.1 Recommended Water Rates
Recommended rates are based on “across-the-board” increases” to the FY21 rates and the break between Tier 1 and Tier 2 Single Family water use is lowered from 13 HCF to 12 HCF. FY22 (current) and recommended Water Quantity rates for FY23 – FY27 are listed in the table below. Rates for all services (except Senior customer classes) are increased at approximately 5 percent per year. Rates for the Senior customer class are increased at approximately 2 percent per year.

The City adjusted the 2018 cost-of-service rates so that changes in the rates were phased-in. The phased-in cost-of-service rates for 2-inch and smaller and 3-inch Fire Line Service are maintained for FY23 – FY27. Other recommended rates are based on “across-the-board” increases” to the FY21 rates adopted in 2018.

Table 4-2. Current and Recommended Meter Service and Fire Line Service Rates City of Pittsburg Resolution 17-13400 established new Municipal rates for the City of Pittsburg’s water consumption and meter charges at 35% of the non-residential rates. The City intends to keep Municipal rates at 35% of the non-residential rates. Quantity and meter service rates for Municipal connections are not listed in the tables above but may be derived from the non-residential quantity rates and meter service rates shown in the tables.

Section 5
Impact of Water Rate Changes on
Customer Bills
Customer bills vary between customer classes and within customer classes. Variation between customer classes is due to different level of services (larger meters and/or fire line services for non-residential) and different rate structures (uniform water quantity rate for non-residential versus inclining block water quantity rates for Single Family customers). Variation within customer classes are due to different levels of water use.

5.1 Single Family Residential Monthly Water Bills
The impact of water rate changes on monthly water bills may vary within the Single Family customer class due to different seasonal levels of water use and a change in the water quantity rate tier break that reflects water conservation efforts.

The figure below compares Single Family monthly water bills over a range of water use from 0 to 20 HCF for customers in Elevation Zone 2 with a ⅝ x ¾-inch meter connection. Note that for water use over 13 units, the increase in the water bill includes a portion of water use billed at the Tier 2 rate rather (the old rate or new rate depending on the bill calculation) than the Tier 1 rate.

Detailed tabulation of monthly water bills over a range of water use from 0 to 40 HCF using current and recommended FY23 water rates are shown in Table B-1 and Table B-2 of Appendix B. Table B-1 includes detailed bill calculations for each elevation zone. Table B-2 includes detailed bill increase comparisons for each elevation zone.

5.2 Residential Monthly Water Bills Surveys
Monthly water bills for Single Family users were compared to those for other agencies. The comparison was for a user with a ¾-inch meter using 10, 14 or 30 HCF of water per month in Zone 2. Results of the survey are shown in the figure below. All bills are based on rates that are adopted for FY23 or currently implemented.

TO: Mayor and Council Members
FROM: Garrett Evans, City Manager
SUBJECT: Adoption of a City Council Resolution Allocating Funding and Approving the Five-Year Capital Improvement Program for Fiscal Years 2022/23 Through 2026/27
MEETING DATE: July 18, 2022

EXECUTIVE SUMMARY
The Five-Year Capital Improvement Program (CIP) for fiscal years 2022/23 through 2026/27 includes projects for construction of new facilities and infrastructure, and for the expansion, rehabilitation, or replacement of City-owned assets. The attached Resolution will approve the CIP for fiscal years 2022/23 through 2026/27 and allocate funds to 28 projects.

FISCAL IMPACT
The total estimated cost of the 239 projects (funded and un-funded) in the CIP exceeds $431 million. Staff is requesting allocation of $9,405,000 to 28 projects. Attached to this report is Exhibit “A” Funding Allocations which lists the project and the requested allocation.

RECOMMENDATION
City Council adopt the attached resolution approving the Five-Year Capital Improvement Program for Fiscal Years 2022/23 through 2026/27 and allocating $9,405,000 to 28 projects as shown on Exhibit “A” Funding Allocations.

BACKGROUND
The City’s CIP is a multi-year plan for construction of new facilities and infrastructure, and for expansion, rehabilitation, or replacement of existing City-owned assets. The CIP is developed by staff and is adopted by the City Council as a guide for prioritization of various projects to accomplish community goals. The CIP is updated on an annual basis to reflect changing priorities and funding availability, and to add new projects and remove projects that have been completed or are no longer needed.

On December 16, 2019, the City Council adopted Resolution 19-13729, adopting the Capital Improvement Program for Fiscal Years 2019/20 through 2023/24. 682
On December 21, 2020, the City Council adopted Resolution 20-13859, approving an Addendum 1 to the Five-Year Capital Improvement Program, and allocating funding to projects.

On April 19, 2021, the City Council adopted Resolution 21-13926, approving an Addendum 2 to the Five-Year Capital Improvement Program to add an additional unfunded project.

On June 21, 2021, the City Council adopted Resolution 21-13922, approving the Five-Year Capital Improvement Program for Fiscal Years 21/22 through 25/26.

Staff developed the attached update to the CIP for fiscal years 2022/23 through 2026/27 through meetings and review of various studies, master plans, maintenance histories, available funding, and other sources.

On June 1, 2022, staff presented a draft of the updated CIP to the City’s Community Advisory Committee for their comments.

On June 14, 2022, the Planning Commission adopted a Resolution affirming conformance of the CIP with the City’s adopted General Plan.

On June 30, 2022, staff presented a draft of the updated CIP to the City's InfrastructureTransportation Subcommittee for their comments.

SUBCOMMITTEE FINDINGS
This item was presented to the Infrastructure-Transportation Subcommittee and Community Advisory Committee where no comments were made regarding the proposed allocations or added new projects.

STAFF ANALYSIS
The proposed 5-Year CIP for FY 2022/23 through 2026/27 reflects previous actions taken by the City Council to allocate funding to CIP projects, as well as a request for allocations of $9,405,000 to projects prioritized for construction (Exhibit A). Also, the CIP references anticipated funding allocations for future years that are not requested at this time.

Projects included in the Five-Year CIP must meet one or more of the following conditions:
• Elimination of potentially hazardous or unsafe conditions and potential liability • Replacement of high-maintenance, inefficient or ineffective infrastructure • Improvement to and/or creation of new services to the public • Compliance with regulatory requirements and mandates
• Stimulation of the local economy and elimination of blighted conditions • Compliance with the City of Pittsburg General Plan
• Preservation of existing assets
The projects listed below, in no particular order, have been prioritized for funding based on a number of criteria and the abovementioned conditions. The City aims at prioritizing the projects that eliminate a potentially hazardous condition, replace high-maintenance infrastructure, comply with regulatory requirements and mandates, and preserve existing assets.
683
A few of the projects listed are grant funded and in order to alleviate potential funding gaps, additional funding has been proposed. Most of the grant funded projects aim to remove a hazardous or unsafe condition and potential liability, and many times the original grant amount is not enough to complete construction. Therefore, additional funding for these projects is required and has been proposed in this fiscal year’s CIP.

In addition, some of the projects that are being proposed for funding involve annual City projects that have been made a priority due to the aging infrastructure and assets located throughout the City. If not already called out in this fiscal year’s CIP, the use of these annual project’s proposed funds will be determined based on the current needs of the City during the year.

The following projects are already funded or are requested to be funded for FY 22/23:

1.ST-11 HSIP 10 Crestview Drive Pavement and Pedestrian Improvement Project [$100,000] – Will enhance the safety for the Crestview neighborhood. (Elimination of potentially hazardous or unsafe conditions and potential liability)

2.ST-52 Annual Citywide Signing and Striping (Repair of Existing Roadway Striping Citywide) [$50,000] - This project is intended to repair Citywide striping and signage when the need arises. The Traffic Engineering team is working on providing a striping plan to Public Works to utilize. Some of the areas that will be targeted in FY 22/23 are Bailey Road, South of Leland and California Ave. (Preservation of existing assets)

3.ST-41 Annual Citywide Fence/Soundwall/Streetlight Replacement/Sidewalk Installation and Repair [$75,000] - This project acts as an emergency fund to replace and repair sound walls, fences, light posts etc. when they are damaged by hit and run drivers. With the inability of the City to pursue insurance companies for damages without knowing who caused the damages to these areas, it is the City’s responsibility to repair these locations.

Most of the time these locations are unknown until they occur during the year, but most of the work gets completed on Buchanan Road. (Replacement of high-maintenance, inefficient or ineffective infrastructure)

4.ST-96 Citywide Arterial Median Conversion [$50,000] - The project account balance has reached a level that now allows Public Works to initiate a project for the removal of landscaping from medians along dangerous arterials and replace with colored decorative concrete. These median conversions will take place along Railroad Ave and sections of W Leland Rd. However, due to the new Railroad Ave Beautification Project this work may have to be planned accordingly so that the designs/colors used matched appropriately. (Elimination of potentially hazardous or unsafe conditions and potential liability)

5. ST-101 FY 22/23 Citywide Traffic Calming [$75,000] - This project will aim at addressing speed safety concerns on E 14th St, Linschied Dr and Manville Ave. These traffic calming methods are currently being designed and the traffic calming methods installed in FY 22/23. (Elimination of potentially hazardous or unsafe conditions and potential liability)

6. ST-59 SB1 FY 22/23 Pavement Management Project [$800,000] - This project will repair and preserve the pavement on E Leland Road using a variety of techniques to extend the useful life of the roadway. Actual limits to be determined based on Pavement Management System and staff input. (Preservation of existing assets) 684

7. ST-60 FY 22/23 Street Maintenance Project [$200,000] - This project will preserve existing pavement in the Central Addition Subdivision through a variety of techniques to extend the useful life of the roadway. Location to be determined based on Pavement Management System and staff input. (Preservation of existing assets)

8. ST-100 SB1 FY 22/21 STIP/OBAG II Pavement Improvement Project [$500,000] - This project will repair and preserve the pavement on West Leland Road from South Broadway to Railroad Avenue and Loveridge Road SR4-Pittsburg Antioch Highway using a variety of techniques to extend the useful life of the roadway. (Preservation of existing assets)

9. S-11 FY 22/23 Traffic Signal Modification Project [$100,000] - This project targets the replacement of traffic signal communication modules, signal indications, battery backups, ped push buttons/mounts, intersection signage replacement and repainting where needed.

It is very difficult to say the exact location at which these upgrades will take place since Public Works goes intersection to intersection and determines what upgrades are needed immediately. However, the intersections that will not be addressed on this CIP project include all the intersections that are scheduled to get upgraded with Contract 2019-01 (HSIP 9 Traffic Signal Improvement Project). To name a few of the locations that are being addressed by the active contract mentioned see below:

W Leland Rd/Bart Station Entrance
W Leland Rd/ Bailey Rd
W Leland Rd/Chestnut Dr
W Leland Rd/Jacqueline
W Leland Rd/Montevideo Dr
W Leland Rd/Dover Way
W Leland Rd/ Crestview Dr
E Leland Rd/ Harbor St
(Replacement of high-maintenance, inefficient or ineffective infrastructure)

10. PK-4 Annual Playground Replacement Project [$75,000] - This project will target replacing the playground at Highlands Park first, then Oak Hills Park. This Highlands Park playground replacement will most likely be completed Summer 2023. (Replacement of highmaintenance, inefficient or ineffective infrastructure)

11. PK-9 Annual Park Features Replacement Project [$75,000] - This project is a fund for Public Works to replace fixtures, drinking fountains, benches and make improvements throughout the year as needed. Public Works will be targeting 8th St Park, Highlands Park, John Henry Johnson Park to be completed in FY 22/23. (Replacement of highmaintenance, inefficient or ineffective infrastructure)

12. PK-10 Biennial Restroom Replacement/Rehabilitation [$250,000] – This project is used to accumulate funding for full park restroom replacements or installs throughout the City.

Currently there is a new single self-cleaning restroom being manufactured to be installed at Oak Hills Park. The objective is to add a similar design at the City Park, but additional future funding will be required due to the larger scope. However, with this allocation the preliminary design can move forward. (Replacement of high-maintenance, inefficient or ineffective infrastructure)
685

13. PK-15 Annual Citywide Park Sign Replacement Program [$50,000] - This project is intended to replace old City park signs with concrete veneer custom signs. The parks that will be targeted in FY 22/23 are: DeAnza Park, Woodland Hills Park, Village Park and Oak Hills Park. (Replacement of high-maintenance, inefficient or ineffective infrastructure)

14. PK-42 Oak Hills Park Restroom [$100,000] – – This is an active project that will be adding a self-cleaning single stall restroom to Oak Hills Park and will be installed by end of Spring 2023. This project is encountering PG&E delays and the City has to wait for PG&E to provide power prior to awarding a contract for installation. These additional funds will add to the project contingency and will alleviate concerns over rising prices. If funding allows, there can be added improvements to the surrounding sidewalk and concrete pad around the new facility. (Improvement to and/or creation of new services to the public)

15. W-1 Water System Master Plan [$100,000] - Every five years, the City prepares and adopts a Water System Master Plan. The Master Plan documents the capacity evaluation of the existing system and the needs of planned future developments. (Preservation of existing assets)

16. W-6 WTP Capital Repairs and Improvement (5058) [$75,000] - Will replace equipment that has lasted beyond its service life at the City’s water treatment plant. (Replacement of high-maintenance, inefficient or ineffective infrastructure)

17. W-8 20/21 Watermain Installation/Replacement Program (Pittsburg Heights) [$2,000,000] - Replace water main, services and valves that have become maintenance problems in the Pittsburg Heights, and West 11th neighborhoods. (Replacement of highmaintenance, inefficient or ineffective infrastructure)

18. W-10 Highlands Ranch Reservoir Recoating [$200,000] - Recoating the inside and outside of the Highlands Ranch Reservoir due to signs of corrosion. (Replacement of highmaintenance, inefficient or ineffective infrastructure)

19. W-11 Automatic Water Meter Reading System (5030) [$300,000] – This is a Public Works project that is a continuation of the replacement of residential water meters with AMRs. However, now Public Works will target replacing commercial and industrial (large) sized water meters throughout the City and expect to complete this replacement by Spring 2023. (Improvement to and/or creation of new services to the public)

20. W-34 WTP Disinfection Modification and Conversion [$1,000,000] - This project consists of disinfection modifications and chlorine conversion at the Water Treatment Plant (WTP).

The existing disinfection system at the WTP will be converted from chlorine gas disinfection to sodium hypochlorite. (Compliance with regulatory requirements, elimination of potentially hazardous or unsafe conditions and potential liability)

21. W-39 Annual Filter Media Replacement [$100,000] - Replacement of expended filter media at the City’s water treatment plant. (Preservation of existing assets)

22. W-40 22/23 Watermain Installation/Replacement Program [$1,000,000] – Replace existing infrastructure that requires high amount of maintenance in the West 11th Street neighborhood. (Replacement of high-maintenance, inefficient or ineffective infrastructure) 686

27. G-2 City Standard and Details Update (Final) [$30,000] – Finalization of the revised City Standards, Specifications and Details. (Compliance with regulatory requirements and mandates)

28. G-26 Install Citywide EV Charging Station [$30,000] – This project will provide Level 2 EV charging to the public in areas near the waterfront, high traffic parks and downtown. (Improvement to and/or creation of new services to the public) Projects that have been partially funded for design and bidding only, will eventually need additional funding before construction can occur. Once bids are opened for these projects, staff will determine the amount and source of additional funds that will be required to complete the projects and request that City Council consider allocation of additional funds.

The Five-Year CIP provides information on potential funding sources for projects, including grants and developer funding. Staff has forecast estimated revenues for the duration of the CIP and has identified available funding sources in the document.

Projects that include grants typically receive the grant reimbursement during and after construction. The amount of funds from developers to support projects listed in the CIP that are anticipated to receive developer funding may not be known until negotiations are complete and agreements are executed.

In compliance with the City’s Fiscal Sustainability Ordinance (Ordinance 12-1363), the proposed CIP project expenditures do not reduce estimated reserves for enterprise fund balances below 30% of operating costs.

Staff will continue to update the CIP annually to account for completed projects, changes in priorities, and changes in funding availability. Additionally, as priorities change, staff may return to City Council to request funding for projects as they are identified.
