Harvest at Limoneira General Fund Cumulative Fiscal Impacts. As shown in Panel A of Table 1, a recurring surplus to the City General Fund is projected for all years of development and after buildout of the Harvest at Limoneira project. The Year 1 surplus of about $288,307 increases to the projected surplus of about $1.705 million at buildout in Year 7. The total projected cumulative surpluses over the 7-Year period are about $7.99 million in undiscounted dollars. This updated analysis does not include the property tax revenues foregone by the City General Fund now accruing to the Ventura County Fire District, and therefore, also does not include fire services costs.
Net New City Cumulative City Fiscal Obligations. Panel B of Table 1 presents the City’s projected annual obligations for approximately two-thirds share of operations and maintenance costs for the new sports park in Harvest at Limoneira, the City’s net new obligation for public street maintenance offset by projected state gasoline tax from the project, and net revenues collected by the City from CFD No. I IA-A Special Tax B used for landscape maintenance, tree maintenance, streetlights, and catch basins.
Accounting for the above, City net new obligations are projected at $8,524 in Year 1 and increase to $376,683 at buildout. The total City net new obligations over the 7-Year period are projected at about $2.35 million in undiscounted dollars. This accounts for $834,675 in CFD revenues over this period.
In Year 3, with the City’s approximately two-thirds O&M cost share of the new sports park (or about
23.33 acres), the City’s sports park obligation is estimated at $608,653 for the remainder of the 7-Year period. The total City obligations over the 7-Year period for the sports park are projected at about $3.04 million in 2023 undiscounted dollars. According to the project development agreement, the sports park is the joint responsibility between the City and School District, and therefore the balance one-third of sports park O&M costs are borne by the School District.
Net annual street maintenance costs are estimated at $63,022 in Year 1 and continue to decline over the 7-year period as the State Gas tax increases constantly with population growth, and offsets increasing portions of these street maintenance costs. Gas tax offsets these costs completely after Year
5. Cumulatively, net City obligations for street maintenance over the 7-year period are projected at about $142,196 in undiscounted 2023 dollars.
Net City Cumulative Fiscal Benefit: As shown in Panel C of Table 1, when the Harvest at Limoneira revenue surplus is matched against the City obligations, net City benefits are projected throughout the development-period and at buildout. The lowered share of City General Fund property tax revenue from tax rate area (TRA) reallocations between the City and the Ventura County Fire District since 2016, has the effect of reducing overall property tax revenues relative to projected development-related costs. The net benefits increase from $279,783 in Year 1 to $1.33 million at buildout. The total net City benefit over the 7-year period is projected at $5.64 million in undiscounted dollars.
Ventura County Fire District: As shown in Panel D of Table 1, a large portion of the property tax revenues previously going to the City General Fund prior to the TRA reallocations now accrues to the Ventura County Fire District. These revenues increase from about $575,602 in Year 1 to $2.34 million by Year 7 for a cumulative 7-year total of $10.42 million in undiscounted dollars.
Detailed Fiscal Impacts. Table 2 presents the detailed projected cumulative fiscal impacts to the City General Fund, the new City cumulative fiscal obligations and the net City cumulative fiscal benefit of Harvest at Limoneira.

Harvest at Limoneira Projected Fiscal Impacts
Development Description
Table 3 presents the development description after buildout for Harvest at Limoneira. The phased units, population, non-residential square feet, employment, park acres and road square feet are included in Table 4.
Acres. Harvest at Limoneira includes approximately 632.7 gross acres, with about 547.9 gross acres located in East Area 1 and about 84.9 acres located in the Santa Paula Gateway Project.
Residential Development. As shown in Panel B of Table 3, Harvest at Limoneira includes a total of 2,348 residential units with an estimated population of 7,032 after buildout. East Area 1 includes a total of 2,050 units (1,750 single family units and 300 apartments), while East Area 2 includes a total of 298 units (250 apartments, including 50 active adult units, and 48 townhomes).
Non-Residential Development. Harvest at Limoneira, East Area 2, includes a total of 461,560 square feet, including supermarket and GAFO retail (Area B), 100-room hotel (Area C), and hospital, medical and general office, and an assisted living center (Area D), as shown in Panel C of Table 3. Total employment generated by these uses is estimated at 1,093 after buildout.
Publicly Maintained Infrastructure. As shown in Panel E of Table 3, a total of 674,160 square feet of publicly maintained streets are estimated for the total Harvest at Limoneira project after buildout, with about 81 percent of the new roadways located in East Area 1. About 8.37 acres of neighborhood parks are in East Area 1 after buildout. Also, a 35-acre community sports park is planned in East Area 1, with the City responsible for approximately two-thirds and the School District for the balance one-third O&M costs, according to the project development agreement.
Assessed Valuation and Property Tax After Buildout
Table 5 includes the estimated assessed valuation, General Fund property tax and General Fund property tax in lieu of VLF for Harvest at Limoneira.
Assessed Valuation. Values per unit are provided by the developer. As shown in Panel B of Table 5, residential valuation in East Area 1 is estimated at about $1.35 billion after buildout. Combined with the estimated residential and non-residential valuation in East Area 2 of $309.19 million, total Harvest at Limoneira valuation after buildout is estimated at about $1.54 billion. For East Area 1, when the estimated assessed valuation at project inception of $45.12 million is subtracted from the new overall project valuation, net new valuation (since project inception) is estimated at about $1.31 million. For East Area 2, when the current assessed valuation of $22.25 million, in constant 2023 dollars, from the County Assessor 2020-2021 tax roll is subtracted from the new valuation, net new valuation is estimated at about $286.93 million at project buildout (development projected to commence starting 2025).
Property Tax. Based on the total assessed valuation, the one percent property tax levy is projected at about $16.61 million after buildout. Based on the tax rate area in which the project is located, the City General Fund receives about 3.84 percent of the basic one percent levy for a total of $637,777 after buildout.
Property Tax in Lieu of VLF. As part of the State’s 2004-2005 budget agreement, the State began to allocate property tax revenues to cities and counties to offset the State reduction of VLF. Property tax in lieu of VLF is projected based on the net increase in assessed valuation from the proposed project since inception, which is estimated at the Citywide average of $1,283 per million of new assessed valuation.
Based on this assumption and the project’s net assessed valuation increase, projected property tax in lieu of VLF is projected at about $1.68 million for EA1 and $368,263 for EA2 after buildout for a total of $2.05 million for Harvest at Limoneira.

Abbreviation: MTCO2e = metric tons of carbon dioxide emissions As shown in Table 3.12-1, construction emissions resulting for the proposed changes in the Specific Plan would decrease by approximately 1,192 MTCO2e per year when compared to the 2015 East Area 1 SP SEIR. The resulting construction emissions would be less than those identified previously in the 2015 East Area 1 SP SEIR. Impacts from construction emissions were previously found to be less than significant without mitigation.
Operation
The amendment as currently proposed would allow the development of up to 10,000 square feet of commercial uses in the Hallock Center District to facilitate the provision of neighborhood-oriented retail commercial uses for residents and visitors to the Sports Park in the Civic District. Based on technical guidance provided by the Governor’s Office of Planning and Research on evaluating transportation impacts in CEQA, adding local-serving retail development improves retail destination proximity, which shortens trips and reduce vehicle miles traveled (VMT). For this reason, adding local-serving retail commercial development would further reduce GHG emissions.
The Specific Plan Amendment as originally proposed would result in a decrease of approximately 1,351 MTCO2e per year as shown in Table 3.12-2: Operational GHG Emissions. This represents a decrease of approximately 4.8% in GHG emissions due to the changes in land use. Additionally, a 4.6-metric tons of CO2e per year per service population threshold was used to determine significance of GHG emissions in the SEIR. The proposed Project is estimated to result in an increase in population of 6,786 6,171, resulting in a ratio 4.0 35 of CO2e per year, which is below the 4.6 CO2e per year threshold. 186

MULTIFAMILY REVENUE BONDS BY THE CALIFORNIA PUBLIC
FINANCE AUTHORITY IN SUPPORT OF AN AFFORDABLE 166 UNIT
MULTIFAMILY DEVELOPMENT, CITRUS FLATS APARTMENTS
Date: April 3, 2024
Agenda Item: 10.A
CITY OF SANTA PAULA
MEMORANDUM
RECOMMENDATION:
Staff recommends that the City Council:
1. Hold a public hearing pursuant to the federal Tax Equity and Fiscal Responsibility Act (“TEFRA”)
2. Adopt Resolution No. 7507 approving the issuance of multifamily housing revenue bonds for the Citrus Flats Apartments in an amount not to exceed $55 million and authorize the City to become a non-charter member of the California Public Finance Authority.
BACKGROUND:
The City Council is being asked to conduct a public hearing pursuant to the federal Tax Equity and Fiscal Responsibility Act (“TEFRA”) and adopt a resolution which would approve the issuance of multifamily housing revenue bonds (the “Bonds”) by the California Public Finance Authority (“CalPFA”) for the purpose of financing the construction of an affordable residential housing development to be located at 18004 East Telegraph Road in the City of Santa Paula (the “Project”). The purpose of the resolution is to authorize the financing to meet a requirement of the Internal Revenue Code of 1986 (the “Code”).
The Code requires that the “applicable elected representatives” of the jurisdiction in which a project to be financed with “private activity bonds” is situated, adopts a resolution approving the issuance of such “private activity bonds” after holding a public hearing which has been noticed in a newspaper of general circulation in such jurisdiction. The City Council is being asked to hold such public hearing which has been noticed as required by the Code. The proposed resolution would act as the approval by the “applicable elected representatives” with respect to the proposed Project.
The adoption of this resolution is one of the steps in the process of financing the proposed Project. The Project has secured a “private activity bond” allocation from the California Debt Limit Allocation Committee (“CDLAC”) and prior to the issuance of bonds, CalPFA will need to adopt a resolution which would approve the execution and delivery of certain bond documents 187
that will reflect the terms of the Bonds.
ANALYSIS:
The CalPFA is a joint powers authority formed to assist local governments, non-profit organizations, and businesses with the issuance of both taxable and tax-exempt debt, and would be the issuing agency for the proposed bonds under this approval. In order for the CalPFA to have the authority to serve as the issuer of the bonds for the Project, it is necessary for the City of Santa Paula to become a non-charter member of the CalPFA. Attached to this report is a copy of the Joint Exercise of Powers Agreement to be executed by a designated signatory of the City.
The Joint Exercise of Powers Agreement provides that the CalPFA is a public entity, separate and apart from each member executing such agreement. The debts, liabilities and obligations of the CalPFA do not constitute debts, liabilities or obligations of the members executing such agreement.
The Bonds to be issued by the CalPFA for the Project will be the sole responsibility of the Borrower, and the City will have no financial, legal, moral obligation, liability or responsibility for the Project or the repayment of the Bonds for the financing of the Project. All financing documents with respect to the issuance of the Bonds will contain clear disclaimers that the Bonds are not obligations of the City or the State of California but are to be paid for solely from funds provided by the Borrower.
STRATEGIC PLAN:
The issuance of the bonds and construction of the project create additional affordable housing in the City, aligning with 2023-25 City Council Strategic Plan Core Values of Diversity/Inclusivity and Equity and enhancement of economic opportunities and community vitality.
FISCAL IMPACTS:
The Bonds would be tax-exempt private activity bonds for the purposes of the Internal Revenue Code and, as such, require the approval of the elected body of the governmental entity having jurisdiction over the area where the project to be financed is located. The City will not be under any obligation to repay the Bond indebtedness. This action does not create any additional debt.
OPTIONS:
As an alternative to Staff's recommendation, the City Council has the following option:
1. Do not adopt Resolution No. 7507. If the resolution is not approved, the Project will not be constructed in the City.

MEMORANDUM
RECOMMENDATION:
Staff recommends the City Council adopt Resolution No. 7508 authorizing a City Affordable Housing Fund loan to FLT Telegraph Partners, L.P. ("Partnership") in the amount of $5,500,000; and the deferral of Development Impact Fees and Water In-Lieu Fees in an amount not to exceed $5,157,949.
Presented by: James Mason, Community & Economic Development Director BACKGROUND:
Project History
The entitled by-right development proposed by Red Tail Multifamily Land Development (“Red Tail”), located on the currently vacant 11.28-acre parcel at 18004 East Telegraph Road (south of East Telegraph Road and east of Whipple Road), will provide, via new parcel map, 298 new apartment units on two new parcels. 166 of the units (56% of the total unit count for the project) are proposed as deed-restricted affordable apartments situated on one new parcel, with the remaining 132 units designated as market-rate apartments on another new parcel.
The project has been designed so that each parcel (component) could stand alone and meet all City codes and requirements, while no readily discernible visual difference exists between the designated areas.
By-Right Entitlement
On October 7, 2020, the Santa Paula City Council adopted Ordinance No. 1305 amending Chapter 16.15 of the Santa Paula Municipal Code to permit all housing ‘by-right’ in all Commercial zones (C-N, C-O, CBD, C-G and C-LI) without discretionary review consistent with the purpose and intent of Government Code Sections 65583.2(h) and (i). 205
By-right entitlement is intended to be the easiest path to qualify for development under the zoning codes of local jurisdictions. Such entitlements have been heavily promoted via new and updated California housing legislation over the past several years in an effort to meet the state’s serious housing shortfall. By-right entitlements are often described as ministerial – a common legal term that also refers to a lack of discretionary approval. To be clear, a development qualified for by-right entitlement must still acquire the necessary permits (grading, construction, stormwater, etc.) in order to proceed.
In addition to providing such by-right entitlement, Ordinance No. 1305 also replaced all C-H (Commercial-Highway) zoning in the Santa Paula Municipal Code with the C-LI (CommercialLight Industrial) designation. The project parcel at 18004 East Telegraph Road (APN: 107-0- 042-015) was thus changed from C-H to C-LI zoning, thereby making residential use permitted by-right onsite.
Affordable Housing Partnership
Red Tail is partnering with Affordable Housing Access (“AHA”) ( www.ahaccess.org) for development of the 166-unit affordable portion of the project. AHA is a 501(c)(3) nonprofit corporation. Founded in 1999, its mission is creating and preserving quality affordable housing and empowering low-income individuals and communities through social services and community building. AHA specializes in partnerships with a wide range of developers, owners, investors, lenders, social service providers, public charities and government to leverage their own capabilities. AHA and its developer partners have constructed, or acquired and rehabilitated, more than 20,000 affordable housing apartments and homes throughout the West.
Financing Information & Tax Credit Application Deadline Red Tail/AHA will apply for tax-exempt bonds and federal and state tax credits to finance the construction of the 166 affordable units in the project, however, they anticipate a financing gap which requires additional funding. Worthy of note is that Red Tail/AHA is not requesting waiver or deferral of any fees related to the 132 market-rate units of the overall project.
Projects requesting private activity bonds and federal/state tax credits are scored competitively. For a project to be competitive, public funds are critical and further enhance the project’s likelihood of obtaining a bond and credit allocation, per California Tax Credit Allocation Committee (“TCAC”) regulations Section 10325 (A)(i). Essentially, the more support a local jurisdiction provides, the more likely the applicant will receive federal and state support.
Additionally, Ventura County is within the Central Coastal Region, wherein only 5.2% of all available bond and tax credit awards statewide are allocated per TCAC regulation 10315(i). Without the requested public funding, this project cannot feasibly be built.
The application deadline for the first round of TCAC funding is April 23, 2024. Again, as these applications are scored competitively and funds are limited, it is critical that the Red Tail/AHA application is submitted in Round 1, as Round 2 will almost certainly be over-subscribed. To be clear, Red Tail/AHA’s request for financial assistance from the City is a key component of their TCAC application.
Financial Assistance Request
206
On June 29, 2023, the City of Santa Paula received an initial request from Red Tail/AHA for financial assistance in funding for the development of the 166-unit affordable housing portion of their project at 18004 East Telegraph Road, now known as “Citrus Flats.” Since that time, staff has worked closely with Red Tail/AHA and the City’s Red Tail Project and Affordable Housing Trust Fund Subcommittees to intensively review and refine the assistance request to a potential total of $10,657,949, while also preserving the highest possible scoring for the competitive TCAC funding application.
This project’s funding recommendation will be an amount up to $10,657,949 comprised of City Affordable Housing Funds and deferral of Development Impact Fees and Water In-Lieu Fees (as set forth below) to assist with development. The funding will be contingent upon documentation of final Loan terms; the attached pro forma (Attachment C); and valid funding commitments from all other sources identified on the pro forma. The project will also include eight (8) project-based vouchers from the Santa Paula Housing Authority (Area Housing Authority of Ventura County).
Composition and approval of the requested financial assistance, as detailed below, is what is being considered at tonight’s meeting.
ANALYSIS:
Loan Composition
The requested loan funding is comprised of three parts:
City Affordable Housing Fund Loan: $5,500,000
Development Impact Fee Deferral (“DIF”) Loan: $2,975,986 Water in Lieu Deferral (“WIL”) Loan: $2,181,963 (not to exceed) Loan Terms
As proposed, the City would provide Red Tail/AHA with funding from its Affordable Housing Fund as secured by the recently adopted Development Agreement with Limoneira-Lewis Community Builders. The City Affordable Housing Fund Loan will accrue interest at a simple interest rate of 4.0% per annum with a loan term of 55 years. Principal and accrued and unpaid interest on the City Affordable Housing Fund Loan will be payable when sufficient residual cash flow (see Repayment Source below) is available to pay a portion of the City Affordable Housing Fund Loan. The principal balance of the City Affordable Housing Fund Loan will self-defease over a 40-year period, commencing in Year 16 of the loan term, in conjunction with the 55-year restricted covenant term.
The DIF Loan and the WIL Loan will accrue interest at a simple interest rate of 4.0% per annum. Principal and accrued and unpaid interest on each of the DIF Loan and the WIL Loan will be payable when sufficient residual cash flow (see Repayment Source below) is available to pay a portion of the applicable loan. The loan term for each of the DIF Loan and the WIL Loan will be 55 years.
The closing of the City Loans will be concurrent with the closing of the tax credit and taxexempt bond financing administered by TCAC. Following the closing of the initial financing of the Project, Applicant will not incur additional debt obligations (other than the permanent financing of the Project following conversion of construction financing), or increase existing 207
obligations, without the written approval of the City.
The City of Santa Paula loan structure will not be in conflict with State of California LIHTC underwriting guidelines.
Repayment Source
The repayment source for the DIF Loan, the WIL Loan and the City Affordable Housing Fund Loan is 50% of the residual cash flow after Applicant’s payment in full of all deferred developer fees and of allowable expenses per the guidelines set forth in the California TCAC Qualified Allocation Plan and related regulations adopted by the Committee. The DIF Loan, the WIL Loan and the City Affordable Housing Fund Loan will be secured by a subordinated lien on the real property, and the Loans will be repaid, and the City’s lien on the real property released, on a capital event.
Pending approval by the City Council of the above-mentioned conditions via Resolution 7508 (Attachment A), the City will provide Applicant a letter of interest confirmed for 270 days following the TCAC award of 4% Low Income Housing Tax Credits (Attachment B).
Loan Interest Options for Council Consideration
Loans made by cities to affordable housing projects in the State of California are subject to strict guidelines in regards to TCAC scoring. Per Cal Code of Reg. Title 4, Division 17, Chapter 1, Section 10325:
Loans must be “soft” loans, having terms (or remaining terms) of at least 15 years, and below market interest rates and interest accruals, and are either fully deferred or require only residual receipts payments for at least the first fifteen years of their terms. Qualified soft loans may have annual fees that reasonably defray compliance monitoring and asset management costs associated with the project. The maximum below-market interest rate allowed for tiebreaker purposes shall be the greater of four percent (4%) simple, or the Applicable Federal Rate if compounding.
Pursuant to review by staff and legal counsel, as well as independent financial advisory review of the proposed loan terms by the City's municipal advisors, NHA Advisors, staff analyzed two interest rate approaches; a 4% simple interest calculation and a 3.44% compounding rate.
Each option has distinct advantages and disadvantages to the City and the developer with simple interest being most predictable but resulting in a lesser accrual over the full term of the loan.
As shown in Attachment E, the potential financial benefit between simple and compounding interest is largely de minimis until Year 15-16, when the accrued interest gap widens to an eventual difference of approximately $15,000,000 over the life of the loan. That said, there is high likelihood that a capital event will occur by Year 15-16, rendering the interest accrual moot, as the City would be made whole at that point.
Red Tail/AHA remains steadfast that the proposed 4% simple interest rate is well above the industry standard and a capital event will likely occur by Year 15-16 (possibly as soon as Year 12-13, depending on market forces) as it is a common exit strategy of tax credit investors following the statutory tax credit delivery and recapture period, and that a compounding interest calculation would derail the project pro forma. 208
Rather than jeopardize the project’s affordable housing funding timeline, staff is recommending approval of the loans at 4% simple interest. However, it remains within the Council’s purview to alter the interest calculation at this meeting if they see fit to do so.
City Affordable Housing Fund Loan Details
At their regular meeting on February 21, 2024, the City Council adopted Ordinance No. 1333, approving an EIR Addendum for the East Area 1 project and Amendment No. 3 to the Development Agreement (Harvest at Limoneira project). A major component of the amended agreement involves the Harvest at Limoneira project developer, Limoneira Lewis Community Builders, LLC, providing a contribution of $5,500,000 to the City Affordable Housing Fund in order to satisfy the requirements of the City’s Inclusionary Housing Ordinance triggered by their request to increase their allowed units by 550. The City would then pass that amount to the Red Tail/AHA project in the form of a “soft” loan.
Section 8.7.2 of the approved Development Agreement states:
Inclusionary Housing. In lieu of providing Very-Low-, Low-, and Moderate-Income housing within the Project, Developer will make the following contributions to the City’s Affordable Housing Trust Fund, which must be used by the City for constructing affordable housing. For the first 1,500 residential dwelling units within the Project, Developer shall contribute a total of $6,500,000 to the City’s Affordable Housing Trust Fund, which will be paid at a per unit rate of no less than $4,642.86 upon issuance of a certificate of occupancy for each market-rate residential unit. For the additional 550 residential dwelling units described in Section 2.2, Developer shall meet or exceed its obligation to construct or fund affordable housing units under the City’s Inclusionary Housing Ordinance by providing the gap financing identified by the City as necessary for the successful development of the affordable multi-family rental housing project in the City proposed by Red Tail Multifamily Land Development, LLC, consisting of 36 very-low income units, 130 low-income units, and 132 market-rate units to be located at 18004 East Telegraph Road (APN: 107-0-042-015) (“Red Tail Project”).
Specifically, Developer shall contribute a total of $5,500,000 to the City’s Affordable Housing Trust Fund, which shall be paid no later than 30 days before City enters a loan or equivalent instrument to fund the Red Tail Project (the “Red Tail Payment Trigger”).
Should the Red Tail Payment Trigger not occur for any reason, in lieu of making the $5,500,000 payment specified above, Developer will (i) contribute a total of $5,500,000 plus an annual increase of $400,000 per year commencing on January 1, 2025, up to a maximum payment of $8,250,000 to the City’s Affordable Housing Trust Fund to be used for alternative offsite rental housing development of at least 50 very-low and low-income units, as determined by City (a “Replacement Project Contribution”), or if no Replacement Project Contribution has been made prior to issuance of the 1,501st certificate of occupancy, (ii) pay an in lieu fee to the City’s Affordable Housing Trust Fund of $15,000 per unit prior to issuance of each certificate of occupancy. City agrees to reasonably cooperate in providing documentation at Developer’s request to ensure appropriate treatment of this contribution for tax purposes, at no risk or cost to the City.
By structuring this way, the City actually doubles the amount of affordable housing that would otherwise have been triggered by the 550 additional Harvest at Limoneira units. Under the City’s Inclusionary Housing Ordinance, 83 affordable units (15% of the 550 additional units) would have been required. Here, the City gains 166 affordable units – 39% (42 units) of the City’s Very-Low Income requirement, and 103% (124 units) of the City’s Low-Income 209
requirement under the current (6th Cycle) Southern California Association of Governments (“SCAG”) RHNA allocation.
DIF/WIL Deferrals
Waiver of City fees is a common tool in assisting the development of affordable housing and meeting Regional Housing Needs Assessment (“RHNA”) goals in California. However, City staff remains keenly aware of the City’s urgent financial and budgetary needs, and the related inability to accommodate fee waivers, as other larger cities might, in facilitating the construction of affordable housing. As such, staff has worked with Red Tail/AHA on fee deferrals only, to ensure the City can benefit from increased affordable housing supply without the detriment of waived fees that the City budget cannot realistically support. A full breakdown of the proposed fee deferrals for both the affordable and market-rate portions of the project is provided as Attachment D.
The City’s certified 2021-2029 Housing Element also provides direction regarding fee deferrals. Section B.11 of Chapter 5: Housing Action Plan states:
“To the extent feasible, the City will defer the payment of development impact fees for 15 years, which would allow affordable housing projects to count that as a public funding source, which helps increase competitiveness when applying for low income housing tax credit allocations.”
While development fee deferrals have not been utilized in past affordable housing projects, the City's new Housing Element policy not only establishes that expectation as a new "tool" toward achieving affordability, but is also consistent with trends across the state as to how local jurisdictions can partner with developers to achieve affordable housing units.
STRATEGIC PLAN:
This project supports the City Council-adopted policy to support the acquisition, rehabilitation and/or new construction of rental projects that focus on populations earning 60% or less of the area median income, and that provide affordable housing to assist these populations.
FISCAL IMPACTS:
Significant current and future (deferred) permitting/development fees and property tax revenues for the project, along with potential sales tax revenues generated by several hundred new City residents living onsite, would be lost if the project could not be completed.
Availability of new affordable (and market-rate) housing may also factor heavily into siting and feasibility of multiple nearby commercial developments (and their associated sales tax revenue) currently proposed or under consideration.
OPTIONS:
In addition to the recommended action, the City Council has the following available alternative options, both of which may have significant impacts on the project's state funding applications and overall feasibility:

Attention: Ron Wu
RE: Award of Funds for Citrus Flats (18004 East Telegraph Road) Dear Mr. Wu:
The City of Santa Paula has received a request for up to $10,657,949 in funding for the development of a 166-unit affordable housing community, located at 18004 East Telegraph Road in Santa Paula.
This project supports the City Council adopted policy to support the acquisition, rehabilitation and/or new construction of rental projects that focus on populations earning 60% or less of the area median income, and that provide affordable housing to assist these populations. This project’s funding recommendation will be an amount up to $10,657,949 in City Affordable Housing Funds and deferral of Development Impact Fees and Water in Lieu fees (as set forth below) to assist with development.
Funding approval was presented to City Council at a City Council meeting on April 3, 2024.
The funding will be contingent upon documentation of final Loan terms; the attached pro forma; and valid funding commitments from all other sources identified on the pro forma for the Project.
Applicant: FLT Telegraph Partners, L.P.
Loan Amount: City Affordable Housing Fund Loan - $5,500,000 Development Impact Fee Deferral (“DIF”) Loan - $2,975,986 Water in Lieu Deferral (“WIL”) Loan – Not to exceed $2,181,963 Loan Terms: The City Affordable Housing Fund Loan will accrue interest at a simple interest rate of 4.0% per annum. The City Affordable Housing Fund Loan term will be 55 years. Principal and accrued and unpaid interest on the City Affordable Housing Fund Loan will be payable when sufficient residual cash flow (see Repayment Source below) is available to pay a portion of the City Affordable Housing Fund loan. The principal balance of the City Affordable Housing Fund Loan will self-defease over a 40-year period, commencing in Year 16 of the loan term.
The DIF Loan and the WIL Loan will accrue interest at a simple interest rate of 4.0% per annum Principal and accrued and unpaid interest on each of the DIF Loan and the WIL Loan will be payable when sufficient residual cash flow (see Repayment Source below) is available to pay a portion of the applicable loan. The loan term for each of the DIF Loan and the WIL Loan will be 55 years. 216
The closing of the City Loans will be concurrent with the closing of the tax credit and tax-exempt bond financing administered by TCAC. Following the closing of the initial financing of the Project, Applicant will not incur additional debt obligations (other than the permanent financing of the Project following conversion of construction financing), or increase existing obligations, without the written approval of the City.
The City of Santa Paula loan structure will not be in conflict with State of California LIHTC underwriting guidelines.
Repayment Source: The repayment source for the DIF Loan, the WIL Loan and the City Affordable Housing Fund Loan is 50% of the residual cash flow after Applicant’s payment in full of all deferred developer fees and of allowable expenses per the guidelines set forth in the California Tax Credit Allocation Committee’s Qualified Allocation Plan and related regulations adopted by the Committee. The DIF Loan, the WIL Loan and the City Affordable Housing Fund Loan will be secured by a subordinated lien on the real property, and the Loans will be repaid, and the City’s lien on the real property released, on a capital event.
Pending the above-mentioned conditions, this letter of interest is confirmed for 270 days following the TCAC award of 4% Low Income Housing Tax Credits.
We are pleased to support the development of Citrus Flats and look forward to its completion. This project will add greatly needed affordable units to the community which will serve low-income households.
Sincerely,

CITY OF SANTA PAULA
MEMORANDUM
RECOMMENDATION:
Staff recommends that the City Council:
1. Receive and file the 2024 Wastewater Collection System and Water Recycling Facility Master Plan
Presented by:
Becca Bugielski, PE, MKN & Associates, Inc.
Michael Nunley, PE, MKN & Associates, Inc.
BACKGROUND:
The City provides wastewater collection services for approximately 31,000 customers with wastewater treatment at the City’s Water Recycling Facility (WRF). The City’s wastewater collection system consists of approximately 59 miles of gravity collection system piping ranging in diameter from 6 inch to 42 inch, less than 1 mile of force main, approximately 1,190 manholes, and three lift stations. The WRF has been in operation continuously since 2010 and is designed to treat wastewater flows up to 4.2 million gallons per day (MGD) with a peak operating capacity of 7.0 MGD. The WRF produces high quality wastewater effluent through the membrane bioreactor treatment process which is released into percolation ponds which recharge the Santa Paula groundwater basin.
Cities rely on Wastewater Master Plans to evaluate system capacity and conditions and to provide comprehensive recommendations for replacements and improvements to the sewer system and treatment facilities. The City last developed a Wastewater Master Plan in June 2012 and in May 2023 the Council approved a contract with MKN and Associates to develop the City’s 2024 Wastewater Collection System and Water Recycling Facility Master Plan (Master Plan). The final plan is being presented to Council and recommends current and future improvements through 2040 informed by measurements of existing sewer flows, condition assessments, estimates of population growth and development, and recent innovations in hydraulic modeling, asset management and mapping. The Master Plan includes detailed mapping of the sewer system and development of a digital hydraulic model that can 235
be used to evaluate impacts of development and population growth. The consultant worked with the Community Development Department to identify and quantify development potential throughout the City including recent additions to the Harvest Development. Based on detailed measurements of existing sewer flows and water use, the consultant developed estimates of future sewer flows associated with future development as well as regional population growth estimates. These estimated flows were input into the sewer model and the model was used to identify system improvements needed to serve existing customers, anticipated Citywide growth and development. In addition, condition assessments were used to identify failing system components and potential upgrades to provide better system management and operations. A detailed condition assessment was performed at the WRF. MKN walked through with plant staff and observed each process and its operations. They then reviewed the new flows projected in ultimate scenarios and ran calculations to review the capacity of each treatment process based off the City’s planned growth. A detailed list of maintenance and capacity projects was then produced.
ANALYSIS:
MKN developed a collection system hydraulic model in Bentley SewerCAD that included the major trunk sewers greater than 10 inches in diameter and other critical connection points throughout the system (flows from new development areas). The model was updated to include current infrastructure improvements and model settings were configured to simulate various flow conditions. Within the hydraulic model, scenarios were developed and evaluated with a focus on the following performance areas: Gravity Pipeline Capacity, Lift Station Pumping Capacity, Force Main Velocities. Based on an evaluation of existing, near term, and ultimate flow conditions, collection system pipeline upgrade projects were identified to increase pipeline capacity to serve existing and buildout flow conditions.
MKN performed a capacity evaluation and condition assessment of the WRF. Various capital improvements were identified. Many major projects were completed in the past several years, including membrane replacements and aeration basin cleaning and repairs. The current Blower Replacement Project will provide major upgrade to the other large condition assessment concerns at the WRF. Upgrading the headworks screening system is necessary to provide redundancy for both existing and future flow conditions. Installation of an additional flow equalization basin to provide emergency storage is also recommended. Additionally, expansion of membrane basins 7 and 8 is proposed to enhance the facility’s capacity to provide redundancy under ultimate future flow and loading conditions.
A comprehensive condition assessment and walkthrough with operation staff identified various needs at the WRF. Improvements included building maintenance, coating improvements, and a series of minor repairs around the facility.
A complete list of recommendations are identified in the attached report: WRF Master Plan Report - Attachment 1.
STRATEGIC PLAN:
The Project supports the currently adopted Strategic Plan in achieving the following goals:
Infrastructure, Transportation & Mobility
Goal: Maintain and develop the City’s infrastructure to be safe, sustainable, innovative and cost efficient.
236
FISCAL IMPACTS:
The Master Plan identifies a total of $ 27.2 million in current and future capital improvements through 2040. The Master Plan identifies $5.8 million in capital improvements needed to address collection system deficiencies to serve existing flow conditions, $2.8 million in capital improvements needed to address collection system deficiencies to serve future flow conditions, $14.8 million in capital improvements needed to address existing operations at the WRF, and $3.8 million in improvements needed to address future growth at the WRF. These capital improvement estimates can be used to inform customer rate analysis as well as development impact fees for improvements. If individual developments are proposed that differ from the model inputs, the sewer system model can be used to evaluate specific development impacts and to identify associated impacts to the sewer system. Additional funding for needed projects will be generated over time through sewer rates as well as development impact fees for improvements tied to specific developments.
OPTIONS:
The Council has the following available alternative options to staff’s recommendations:
1. Do not receive and file the 2024 Wastewater Collection System and Water Recycling Facility Master Plan, provide alternative guidance and request staff to return to Council with a revised Master Plan at a future meeting.

Based on the City’s historical WRF influent flow data,
flow monitoring data, and previous reports existing
wastewater flow conditions were established as follows:
average day flow of 2.6 MGD, peak hour dry weather
flow of 5.2 MGD, and peak hour wet weather flow of 7.7
MGD.
MKN reviewed data from the 2020 Census, 2020 Urban
Water Master Plan (UWMP), 2021-2029 Housing Element and, Land Use Element. Based on an evaluation of the service area population, major planned developments, limited infill development, and expansion areas a total of 4,600 dwelling units were assumed to be constructed at full buildout of the City.
MKN developed future flow estimates for the City’s approved development projects, current specific plan areas, vacant properties, and expansion areas. This established buildout wastewater flow.
Based on the findings in the Master Plan, it is anticipated the average day wastewater flows will increase by 38%
at full buildout of the City (including expansion areas). 254

Collection System Evaluation
Lift Station Condition Assessment
FINDINGS
Ê Majority of existing trunk collection
system has sufficient capacity to
serve existing and buildout flow
conditions
Ê A total of 19 collection system pipeline upgrade projects identified to increase capacity
Ê Lift stations have sufficient pumping
capacity to serve existing and future
flow conditions
Ê A total of 3 rehabilitation projects
identified to increase reliability of
existing lift stations
MKN developed a collection system hydraulic model in Bentley SewerCAD that included the major trunk sewers greater than 10-inches in diameter and other critical connection points throughout the system (flows from new development areas).
The model was updated to include current infrastructure improvements and model settings were configured to simulate various flow conditions.
Within the hydraulic model, scenarios were developed and evaluated with a focus on the following performance areas:
Ê Gravity Pipeline Capacity
Ê Lift Station Pumping Capacity
Ê Force Main Velocities
Based on an evaluation of existing, near-term, and ultimate flow conditions recommended collection system pipeline upgrade projects were identified to increase pipeline capacity to serve existing and buildout flow conditions.
As part of the Master Plan, MKN visited the three lift stations sites with operations staff to observe existing conditions. During these visits, MKN observed the general configuration of the lift stations and reviewed the following items:
Ê Configuration / Pumps
Ê Lift Station Safety Features
Ê Flood Resilience, Backup Power
Ê Wet Well Structure, Coatings, Instrumentation
Ê Access
Ê Bypassing Provisions
Ê Site Features
Based on these observations and input from operations staff, MKN developed a list of CIPs to address observed physical deficiencies at each lift station to improve system reliability and extend the useful life of the existing equipment.

Project prioritization was based on the following:
Ê Projects to address existing capacity deficiencies
Ê Projects to address condition-based deficiencies
Ê Projects to address near-term capacity deficiencies
Ê Projects to address buildout capacity deficiencies
Based on coordination with City staff, the recommended projects were identified. The proposed CIP allocates funds in proportions of 1% for Lift Station (LS) Projects, 32% for Collection System (CS) Projects, and 67% for Water Recycling Facility (WRF) Projects over the next 15-year budgeting period with an annual breakdown.

1.0 INTRODUCTION AND OVERVIEW
This section provides an overview of the City of Santa Paula’s (City) goals, study area, and scope of work for the Wastewater Collection System and Water Recycling Facility Master Plan (Master Plan).
1.1 Project Purpose
The purpose of this Master Plan was to identify improvements to the City’s existing wastewater collection, treatment, and disposal facilities necessary to meet existing and future wastewater conditions and to develop a comprehensive improvement program to assist the City in long-term planning and budgeting. The planning horizon for this Master Plan is the build‐out timeframe estimated to occur in the year 2040 per the City’s adopted General Plan.
1.2 Study Area
The City is located approximately 17 miles inland from the Pacific Ocean in central Ventura County within the Santa Clara River Valley, approximately 65 miles northwest of Los Angeles, 44 miles southeast of Santa Barbara, 12 miles east of the City of San Buenaventura and approximately 9 miles west of the City of Fillmore. The current wastewater service area boundary encompasses approximately 5.4 square miles (3,456 acres) within the City limits and serves an estimated population of 30,389 as reported by the California Department of Finance for 2020. The City’s wastewater service area is primarily single- and multi-family residential land uses, with some light commercial and industrial land uses. The City owns and operates approximately 59 miles of wastewater collection pipelines, three lift stations, and a Water Recycling Facility (WRF), which provides wastewater treatment and disposal.
Figure 1-1 provides an overview of the current City limits, Sphere of Influence (SOI), and General Plan Expansion Areas. These combined areas define the limits of the “Study Area” for the Master Plan.

INTRODUCTION AND OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 1-3 Flow Monitoring Study
MKN coordinated with Gold Coast Environmental to perform flow monitoring within the City’s wastewater collection system over a four-week dry-weather period. MKN performed the following tasks as part of the flow monitoring study:
❑ Coordinated placement of four flow meters throughout the City’s collection system to obtain representative flow information
❑ Coordinated sewer pipeline cleaning with Ventura Regional Sanitation District (VRSD) ❑ Prepared a collection system/flow monitoring site map showing the existing collection system, parcels and flow monitoring basin areas
❑ Received and reviewed weekly flow monitoring data provided by Gold Coast Environmental ❑ Collected daily rainfall data from the City
❑ Completed a comprehensive analysis of the flow monitoring data including a summary of the estimated average day and peak hour flows
The data from the flow monitoring study was used to determine average day conditions, and dry-weather peak hour flow conditions within the City’s collection system, and used in the development of sewer generation rates. For wet weather conditions, MKN utilized a conservative wet-weather peaking factors based on available information provided by the City.
Wastewater System Mapping
Currently the City does not have their wastewater collection system data stored in Geographic Information System (GIS) or a hydraulic model. However, the City has an existing AutoCAD wastewater collection system basemap. The hydraulic model was developed using the AutoCAD basemap including information such as pipe geometry, elevations, pipe diameter, pipe material and pipe roughness coefficients. MKN completed the following tasks to develop the hydraulic model:
❑ Imported the existing AutoCAD layers into SewerCAD
❑ Added elevation data from available AutoCAD mapping and available asbuilts ❑ Verified elevation data with one meter resolution Digital Elevation Model (DEM) ground scan of the Santa Paula area from United States Geological Survey (USGS) Development of Wastewater Generation Rates
To develop wastewater generation rates for residential, commercial, and industrial land uses within the Study Area, MKN acquired water billing data for all area users, assigned the users to a GIS parcel layer, developed per acre 263

INTRODUCTION AND OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 1-4 demand factors based on land use, and estimated a preliminary wastewater generation value based on the assumption that a certain percentage of water consumed returning to the collection system as wastewater. The preliminary wastewater generation values were compared to the newly acquired flow monitoring data and return factors were adjusted as required to match recorded flow data. Once the return flow percentage was developed, wastewater generation rates for the various user categories were generated based on their water consumption.
Wastewater Flows and Allocation
MKN created a GISlayer to identify the parcels that are located upstream of each sewer manhole (otherwise referred to as a “sewershed”) that were included in the hydraulic model. Each sewershed area was assigned with a sewer manhole identification number. This process allowed for automated assignment of calculated flows to manholes throughout the collection system. This allocation method has been successfully applied to other collection system modeling/master planning projects that MKN has worked on for other public agencies. Once the flow allocation process was completed, MKN imported the average daily flow (ADF) data into the collection system model.
Future Development and Expansion
MKN worked with City staff to determine the potential growth and/or redevelopment areas for the City. The City provided information with respect to where growth was anticipated to occur and the number of potential units and/or land uses. MKN developed a GIS layer to document the locations of growth, which was used to assign the future flows to locations in the updated hydraulic model. Conceptual facilities (pipeline upgrades) were sized to serve the projected growth areas and included in the model analyses.
Hydraulic Analysis
MKN developed design criteria based on City and industry standards to: 1) evaluate the existing wastewater collection system, 2) identify deficiencies to serve existing and future flows, and 3) develop recommended system improvements to address identified deficiencies. The analysis included evaluation of both the gravity collection pipelines and lift stations. With a hydraulic model developed for the Study Area, MKN ran the following model simulations to identify capacity deficiencies to serve both existing and future flow conditions:
❑ Existing Flow Conditions
o Average Day Flow (ADF)
o Peak Dry Weather Flows (PHDWF)
o Peak Wet Weather Flows (PHWWF)
o Capital Improvement Plan Projects Identified to Correct System Deficiencies ❑ Near-Term Flow Conditions
o Average Day Flow (ADF)

Lift Station Assessment
MKN completed a limited hydraulic evaluation and visual inspection of the existing lift stations including wet wells, piping, valves, control panels, and site civil improvements to document existing conditions and potential deficiencies.
WRF Capacity Analysis
MKN performed a comprehensive capacity evaluation of the existing capacity of the WRF including hydraulics, treatment, and disposal limitations of existing plant processes to serve existing and ultimate conditions. MKN reviewed existing relevant reports and available information to estimate existing and ultimate flows and loadings (strength of wastewater) based on plant records and typical duty factors. The following tasks were performed as part of the WRF capacity analysis:
❑ Summarize existing influent flows, loadings, and treated effluent quality ❑ Review design criteria for existing plant equipment
❑ Identify capacity deficiencies
WRF Condition Assessment
A condition assessment of the WRF was performed to review the condition of existing structures and equipment to determine necessary condition-based upgrades and improvements. As part of this effort, MKN visited the WRF site to document existing equipment conditions and interview the plant operators. MKN developed a comprehensive list of condition-based deficiencies.

INTRODUCTION AND OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 1-6 Capital Improvement Project Plan
MKN developed a capital improvement project (CIP) plan for the existing collection and treatment systems that included capital projects needed to: 1) resolve existing system deficiencies, and 2) accommodate future expansion (assumed to occur by buildout). MKN developed a project list identifying the size and location of required facilities, priorities, possible cost-sharing between existing and future users, triggers (e.g. what flows or number of equivalent dwelling units), and estimated project schedules.
Estimated construction costs for the improvements were developed based on current market cost information and recent local bids for similar projects. The estimated costs include estimates for project administration, design, construction management and project contingency. MKN developed figures depicting the locations of the recommended CIPs for existing and future conditions.
Master Plan Report
A draft version of the Master Plan was compiled to summarize the efforts and results for the tasks described herein.
After a consolidated set of comments were received from the City, MKN revised the draft Master Plan and presented an overview of the findings and recommendations at a regularly scheduled City council meeting. Comments on the draft Master Plan were integrated into the Final Master Plan. 266

2.0 LAND USE AND FUTURE GROWTH
This section provides an overview of the existing land uses, potential development, and future population growth within the Study Area.
2.1 Land Use
The City is one of the oldest cities in Ventura County, with existing land uses that reflect over 120 years of building and development. The largest land use is comprised of residential development and approximately 44% of the City is dedicated to single-family residential, multi-family residential, and mobile homes. Commercial development and industrial development make up another 11% and 7% of the City’s land use, respectively, with another 17% apportioned to specific plans for future development already located within the City’s SOI.
The City’s SOI includes approximately 7,300 parcels. Figure 2-1 and Table 2-1 provide a summary of the 2040 General Plan land uses within the City’s SOI.
Table 2-1: Existing Development of Land Use Types
Land Use Category Gross Acres Percent of Total
Single-Family Residential 1,074 32%
Multi-Family Residential 334 10%
Mobile Homes 82 2%
General Commercial 349 10%
Commercial Office 43 1%
General Industrial 244 7%
Public Facilities 73 2%
Parks and Recreation 11 <1%

2.2 Existing Sewered Parcels
The City’s land uses can be divided into sewered and un-sewered parcels. Sewered parcels are parcels that are connected to the collection system and generate wastewater flow that is collected at the WRF. Sewered parcels include occupied residences, public facilities, commercial businesses and offices, and industrial facilities. Unsewered parcels are parcels that are not connected to the collection system and include vacant lots, open space, and parks. Since the City does not maintain data to indicate which properties are connected to the collection system, MKN assumed that every parcel tied to an existing water billing account (excluding irrigation uses) within the City’s SOI was a sewered parcel. All other parcels were considered un-sewered and not included in the collection system analysis, unless identified with future development potential. To identify sewered parcels, MKN reviewed 2022 billing records and assigned each billing account to the parcel it overlapped. Table 2-2 provides a summary of sewered parcels by land use type in the City’s SOI.
Table 2-2: Sewered Parcels by Land Use in the City’s SOI Land Use Number of Parcels Acreage
Single-Family Residential 3,405 829
Multi-Family Residential 1,890 278
Mobile Homes 6 57
General Commercial 499 266

General Industrial 99 130
Public Facilities 23 114
Airport 9 47
Specific Plan 12 124
Total 6,121 1,885
Of the City’s approximately 7,300 total parcels and 3,382 acres, 6,121 parcels covering an area of 1,885 acres were considered sewered parcels for the Master Plan.
2.3 Future Development
To estimate potential future residential, commercial, and industrial development within the City, MKN worked with the City’s Community and Economic Development department to review existing planning documents to identify properties and/or areas with future development potential within the City’s SOI. MKN also reviewed and considered areas identified as expansion areas for future annexation into the City’s SOI. The planning information used to identify potential future development included the following documents:
❑ 2021 - 2029 Housing Element
❑ 2040 General Plan – Land Use Element
The only future development outside of the City’s SOI included in the Master Plan capacity evaluation included the expansion areas as identified in the 2040 General Plan. 271

2.3.1 2021 – 2029 Housing Element
The City is required to prepare a Housing Element every eight years to identify and address housing needs, housing goals, policies, and programs. Based on forecasted growth of households in the City, the Regional Housing Needs Assessment (RHNA) determined that 657 new housing units would need to be constructed prior to the end of 2029.
In response to the RHNA, the City demonstrated a significant surplus in housing capacity to meet this housing need, as summarized in Table 2-3.
Table 2-3: Land Inventory Summary (Within City SOI)
Development Type Total Housing Units
Approved / Pending Projects1 676
Vacant Residential Sites 117
Vacant Commercial Sites2 812
Total Future Housing Capacity 1,605
RHNA Housing Units Required 657
RHNA Surplus / (Deficit) 948
Notes:
1. Excludes Specific Plan developments
2. The 2021 – 2029 housing development identified vacant commercial sites for residential development
3. The East Area 1 Specific Plan was not included in the land inventory summary. In addition, this did not include any future expansion area developments
2.3.2 2040 General Plan – Land Use Element
The 2040 General Plan is a fundamental policy document for the City, providing the framework for managing the City’s physical and economic resources now and in the future. As part of the 2040 General Plan, the City developed a Land Use Element to guide how the City plans, develops and supports land use, which includes information on future specific plan projects and potential expansion areas to the City’s SOI.
The Land Use Element identifies the following two Specific Plan developments within the City’s SOI that are currently under construction or soon-to-be constructed:
❑ SP-3 East Area 1 Specific Plan: The largest anticipated future development project within the City’s SOI is the East Area 1 Specific Plan (“Harvest at Limoneira”). This Project encompasses approximately 495 acres in east Santa Paula, with an anticipated build out of 2,050 housing units. Per the “Wastewater System Master Plan Amendment – Harvest at Limoneira (East Area One)” report, 520 units were occupied in November 2022, leaving 1,530 housing units left to be developed for the future condition ❑ SP-4 East Gateway Specific Plan: The East Gateway Specific Plan Area in east Santa Paula includes 670,000 square feet of general commercial space
The Land Use Element also identified several expansion areas beyond the City’s current SOI that are considered to have potential for future annexation and development. Table 2-4 below provides a summary of the different Expansion Areas and development potential.

3.0 EXISTING AND PROJECTED WASTEWATER FLOWS
This section provides an overview of the estimated existing and future flow conditions within the Study Area including flow validation through a flow monitoring study.
3.1 Water Recycling Facility Historical Flows
This section provides an overview of the historical influent wastewater flows from the Water Recycling Facility (WRF).
Historical influent wastewater flows are typically composed of wastewater flow form residential, commercial, and industrial uses and inflow / infiltration (I/I). I/I flows occur due to precipitation events and groundwater infiltration.
Inflow is the water entering a collection system and service connections from manhole covers, roof and foundation drains, or cross connections from storm sewers and catch basins. Infiltration is groundwater entering a collection system through cracks in manhole walls, defective pipes, pipe joints, or connections. While inflow varies rapidly with rainfall conditions with flows rising and falling within minutes or hours of a significant precipitation event, infiltration is relatively constant over a period of days, weeks, or even months in areas of high groundwater near sewer services.
The City has not conducted a recent I/I study, but potential inflow and infiltration impacts to WRF influent wastewater flows can be inferred by comparing precipitation to wastewater flows and calculating the difference between wet weather and dry weather peak daily flows. Figure 3-1 provides a comparison between total precipitation and average monthly WRF effluent flows.
Based on Figure 3-1, there does not appear to be a consistent correlation between significant precipitation events and higher than average monthly influent wastewater flows. However, VRSD staff have observed significant I&I at the WRF when the City receives more than 1 inch of rain.
Table 3-1 provides a summary of the historical wastewater influent records from 2014 to 2022. Peaking factors in the table below were determined by taking the ratio of the flow condition above the peaking factor row to the ADF. 277

Notes:
1. Existing flow conditions were based on a three-year average from 2020 to 2022
2. Months with cumulative rainfall over 0,25 inches were considered wet months
3.2 Wastewater Flow Conditions
The following wastewater flow conditions were used to evaluate the City’s collection, treatment, and disposal systems to serve existing and future flows.
3.2.1 Average Day Flow
Average Day Flow (ADF) is the average daily wastewater flow over the course of a year and is obtained by averaging the monthly flows conveyed to the WRF through the course of a year and converting to a daily flow rate. The ADF was determined using a three-year annual average from 2020 to 2022 influent WRF flows.
3.2.2 Maximum Month Flow
Maximum Month Flow (MMF) is the average daily flow during the month featuring the highest cumulative flow.
3.2.3 Average Dry Weather and Wet Weather Flows
Average Dry Weather (ADWF) and Wet Weather (AWWF) Flows are the average daily flow rates experienced during dry and wet weather months respectively. Consideration of average dry and wet weather flows allows analysis of 281

City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 3-4 treatment systems at appropriate flow rates and temperatures for the dry and wet season. Precipitation of 0.25 inches or more per month was assumed to identify wet weather months.
3.2.4 Peak Day Dry Weather Flow and Wet Weather Flow
Peak Day Dry Weather Flow (PDDWF) and Wet Weather Flow (PDWWF) represent the highest daily flow rates experienced at the WRF during dry and wet weather months, respectively.
3.2.5 Peak Day Flow
Peak Day Flow (PDF) represents the maximum daily flow rate experienced at the WRF and issued to design or evaluate hydraulic retention times for certain treatment processes.
3.2.6 Peak Hour Dry Weather Flow
Peak Hour Dry Weather Flow (PHDWF) is the maximum flow experienced within one hour during dry conditions and is one of two flow conditions typically used for sizing collection system gravity pipe and lift stations. The existing peak dry hour flow conditions were based on the results of the flow monitoring study. As identified in Table 3-4, PHDWF peaking factors of 1.7 to 2.2 were observed during the flow monitoring study and the flow meters observed an average peaking factor of 2.0.
3.2.7 Peak Hour Wet Weather Flow
Peak Hour Wet Weather Flow (PHWWF) is the maximum flow experienced within one hour during wet conditions and is one of two flow conditions typically used for sizing collection system gravity pipe and lift stations. The existing peak wet hour flow conditions were based on a peaking factor of 3.0 identified in the design criteria of the previous 2012 WWMP and verified by the results of the updated flow monitoring study.

The flow monitoring study collected baseline dry weather flow conditions within the Study Area. Existing dry weather peak hour flow conditions were based on the results of the flow monitoring study and do not include any increase in flow from rain events.
MKN was not scoped to complete wet-weather flow monitoring for this project and PHWWF conditions were based on information from factors from the City’s Wastewater System Master Plan dated June 2012. To verify observed pipeline capacity deficiencies during PHWWF conditions, the City may consider completing a more comprehensive I/I in the future and updating the PHWWF conditions within the hydraulic model.
3.4 Wastewater Return Factors
To estimate the distribution of wastewater flows across the collection system and estimate future wastewater demand, MKN assigned a water to wastewater return factor to each sewered parcel based on its land use. To determine the return factor for each land use type, MKN developed preliminary wastewater return factors in Table 3-5 based on the existing ADF from Section 3.3.1, 2020 to 2022 water billing data, 2020 to 2022 WRF ADF, and sewered parcel information from Table 2-2. These return factors were then assessed using the flow monitoring study.

4.2.1 Harding Park Lift Station
The Harding Park Lift Station is located in a parking lot planter, 15 feet northeast of the Harding Park restroom. This lift station collects flows from the Harding Park restroom and a residential home located on the premises of the park. A photo of the lift station wet well and valve vault is shown in Figure 4-3.
Access to the lift station is through the park’s parking lot. This station has a two submersible pumps controlled by floats as the primary level sensors. The wet well can be accessed through a steel hatch cover set at grade.
4.2.2 Harvest Lift Station
The Harvest Lift Station is located on Old Hallock Drive, south of Highway 126, adjacent to an RV storage yard. This lift station collects mainly residential flows from the adjacent neighborhood. A photo of the lift station wet well and valve vault is shown in Figure 4-4.
The gated lift station is the newest station in the City, approximately three years old. This station houses three 15-horsepower (HP) submersible pumps. For level sensing, this system has both primary and backup level sensors. The primary is a pressure transducer and four floats act as backup level sensors. These devices, when triggered, send a signal to a PLC controller to activate the pumps.

4.3 Description of Water Recycling Facility
The WRF was constructed in 2010 under a design-build-operate-finance (DBOF) agreement. Phase I was completed at that time and was intended to treat an average day flow of 3.4 MGD. The facility was planned to accommodate a future Phase II expansion that would treat a total of 4.2 MGD on an average day flow basis. Currently, both the plant and collection system are operated under a contract with Ventura Regional Sanitation District (VRSD), who is responsible for daily management and permitting compliance.
Figure 4-6 depicts the process flow schematic for the WRF. Raw wastewater enters the influent lift station via a 42- inch diameter HDPE gravity sewer line. Raw influent is directed to two separate concrete channels in the headworks screening structure. These channels direct flow through coarse screening, grit removal, and fine screening equipment prior to discharge to the pre-anoxic basin splitter channel. From there, the pre-anoxic basin diversion channel controls flow into any combination of the three anoxic basins where denitrification of a mixture of raw screened wastewater and recycled activated sludge flow is achieved. Subsequently, the water progresses to the aerobic basins for oxidation of organic carbon and nitrification. Separate aeration zones allow the operators to control air flow to different areas within the basins. Mixed liquor is pumped to the membrane tank forebay/channel and distributed to the membrane bioreactor (MBR) tanks. Following MBR filtration, the tertiary-treated water undergoes Ultraviolet (UV) disinfection before flowing into a concrete splitter box, then to onsite percolation ponds for disposal. Some treated effluent is reclaimed for on-site water reuse, particularly for operations like equipment washdown. The WRF was designed to serve recycled water users in the future but users have not yet been identified.
Waste Activated Sludge (WAS), is transferred from the membrane tank effluent channel to one of three aerated sludge digestion basins. In these basins, volatile organics are further oxidized. The sludge’s volume is decreased through a gravity belt thickener and the sludge undergoes dewatering via a screw press before being transported offsite for disposal.
The WRF is operated in accordance with Waste Discharge Requirements (WDR), Order No. R4-2018-0022-A01, in tandem with a Cease-and-Desist Order (CDO), Order No. R4-2018-0023-A01, attached as Appendix C. These regulations were adopted by the Los Angeles Regional Water Quality Control Board (RWQCB) on February 8, 2018 and amended in May 2022.
As discussed later in this report, the City is currently developing a chloride removal system to improve WRF effluent quality prior to percolation. The CDO is the basis for implementing this project.
4.3.1 Influent Lift Station
An open-channel Doppler flowmeter monitors flows entering the facility through a metering manhole situated on the 42-inch diameter influent gravity pipeline prior to entering the influent lift station (ILS). The influent sewer lift station was constructed to accommodate a firm peak flow capacity of 17.0 MGD (11,800 GPM) even when one pump is out of service.

EXISTING SYSTEM OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 4-7 The station is comprised of a concrete wet well equipped with four pumps with variable frequency drives (VFDs).
Excess flow above the capacity of the pumps causes an increase in the wet well level and is passively diverted into the two equalization basins by flowing over an overflow weir. Gated outlets within the surge equalization basins enable stored sewage to be redirected back to the ILS when flows are lower, then subsequently pumped through the headworks.
The ILS pumps connect to a 16-inch diameter ductile iron pipe (DIP) riser, which then manifolds into a 24-inch DIP force main. The force main transports raw sewage to the headworks inlet. The flow rate of the influent is measured at the outlet of the headworks structure. Details for the ILS major equipment are summarized in Table 4-2.

4.3.2 Headworks
The headworks system at the WRF utilizes two-stage screening coupled with a dedicated grit removal system. Raw wastewater is pumped from the lift station to the enclosed headworks building which also houses the sludge thickening and dewatering systems as well as the aerobic digester blowers. Each headworks train is composed of an 8.5 MGD coarse screening unit, an 8.5 MGD vortex grit separation unit, and a 6.9 MGD fine screening unit. This parallel arrangement provides redundancy and allows for maintenance of screening equipment without diverting unscreened sewage downstream.
In the headworks, wastewater flows into one of the two headworks trains where it goes through a coarse screen, grit removal chamber, and a fine screen in this sequence prior to continuing to the next treatment process.
As solids collect on both the coarse and fine screens, a collection trough with screw-type compactor and washer receives screenings from the screens and discharges them into a bagging system for offsite removal.
Following the coarse screen process, the wastewater flows through a vortex-type grit chamber. Settled grit is pumped to a cyclone vortex-type grit classifier and periodically extracted to prevent excessive hardening. With a 305
DRAFT
EXISTING SYSTEM OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 4-8 spray wash system, the grit classifier cleanses organics from the grit and mitigates odors. Grit is discharged to a horizontal conveyor equipped with an automated bagging system for convenient disposal. Any remaining water within the classifier is returned to the vortex chamber for further processing.
The fine screens provide a final stage of inorganic solid removal and prevent damage to downstream membranes.

4.3.3 Primary and Secondary Equalization Basins
The WRF features two interconnected equalization (EQ) basins designed for management of short-term diurnal peak flows. These basins operate in series and provide a combined storage capacity of 1.05 million gallons.
The primary EQ basin, situated adjacent to the east wall of the influent lift station, is comprised of an epoxy-coated concrete tank measuring 40-feet wide by 45-feet long by 23-feet maximum liquid depth, with a working volume of 281,100 gallons. This volume was sized to attenuate a peak flow of up to 10.4 MGD over a 10-hour period per Trussell Technologies, Inc., Evaluation of Biological Design and Process Sizing Technical Memorandum (2008) 306

4.3.5 Aeration Basins
Biological oxidation, including carbon removal and nitrification of incoming ammonia, occurs within the aeration basins. These basins each measure approximately 72 feet in length by 38 feet in width by 21.7 feet maximum liquid depth and possess a working volume of approximately 59,400 ft3 (~444,000 gallons each).
Aeration is provided by four dedicated blowers and a zoned fine bubble diffuser system. Within each basin, there are a total of 69 fine-pore diffuser panels organized into three zones, with decreasing diffuser density as water progresses through the basin. The initial zone ensures thorough mixing of influent from the anoxic basin and mixed 307

Subsequent zones maintain adequate oxygen levels for biomass growth and activity while optimizing the growth of organisms that promote aerobic digestion without causing foaming or settling issues. DO sensors allow the operators to manually adjust blower speed via VFDs. The City is currently implementing an ammonia control project to automate blower operations.
Return activated sludge (RAS) troughs are integrated into the basin centerline structure, serving as both weirs and channels to regulate high water levels and return mixed liquor to the Anoxic Basins and to the front end of the Aerobic Basins. Each aerobic basin features a 4 HP, 4,700 GPM mixed liquor suspended solids recycle pump, directing a portion of mixed liquor from the back of the aerobic basin back into the anoxic basin.
From the end of the aerobic basins, wastewater is pumped to the membrane bioreactor (MBR) forebay channel using the MBR feed pumps. Table 4-6 summarizes the major equipment associated with the aerobic basins.

EXISTING SYSTEM OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 4-11 Both the ML collection and MLSS recirculation channels contain a network of fine bubble tube aeration diffusers.
The diffusers scour the membranes to help prevent fouling and ensure that any solids in channels remain suspended, preventing accumulation of settled sludge. Each of the 72 fine bubble tube diffusers (36 in each channel) delivers 3 to 10 SCFM, with a maximum capacity of 17 SCFM. Air for this process is delivered by the membrane blowers.

4.3.7 MBR Basins
The WRF performs biological treatment in three parallel process trains with six membrane bioreactor (MBR) basins.
After passing through the aerobic basins, MLSS is pumped into the ML collection channel which distributes flow into each pair of membrane basins.
The membranes are submerged within the membrane basins and rely on VFD-equipped rotary lobe suction pumps (permeate pumps) that create a vacuum on the permeate side of the membranes. These pumps discharge treated wastewater to a common 24-inch diameter DIP header leading to the UV tank structure.
During the permeate extraction process, solids form a sludge layer on the membranes. To prevent excessive buildup, the membrane modules’ operation includes periodic backflushing with permeate water, facilitated by the permeate pumps. Membrane blowers also provide scouring of the membrane surface through diffusers mounted at the bottom of the membrane basins.
309
DRAFT
EXISTING SYSTEM OVERVIEW
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 4-12 The membrane filtration modules also have a clean-in-place (CIP) system for both maintenance and recovery cleaning, carried out within the tanks. Maintenance cleaning involves periodic injection of low doses of sodium hypochlorite and citric acid into the membrane module permeate/back-flush lines.
Mixed liquor continually overflows to the ML recirculation channel for diversion back to the aerobic basins or for pumping Waste Activated Sludge (WAS) to the aerobic digesters. Table 4-8 summarizes the major equipment associated with the MBR modules and tanks.

4.3.8 UV Disinfection System
Permeate is disinfected using ultraviolet (UV) disinfection prior to discharge to percolation ponds or reuse within the WRF. The process exposes the wastewater to UV light which damages the genetic material of microorganisms, preventing their ability to reproduce, and rendering them non-infectious. The WRF uses a low pressure ultra-high output amalgam lamp to accomplish their disinfection.
This disinfection process is performed within covered concrete channels that receive flow from the 24-inch diameter DIP membrane permeate header. This flow enters the UV tank structure and discharges into a pre-UV channel wet well through which has manually controlled slide gates to control flow into the UV channels. The UV modules are positioned within a concrete channel. There are a total of 10 banks for both concrete channels with each bank 310

Maintaining the water level within the channel is crucial for the disinfection system to ensure full submersion of the UV lamps, as it requires an adequate contact time with UV radiation. To maintain lamp submergence, water level is regulated by weirs and a level gate. The PLC adjusts the number of activated lamps based on flow rate and baffles within the channels direct flow for optimal contact. After exiting the UV channel, treated water is discharged for plant reuse or is discharged into the 30-inch effluent pipeline that feeds the diversion structure, which then directs flow to all three percolation ponds.

4.3.9 CIP Storage Tanks and Foam Spray System
The Clean-In-Place (CIP) storage tanks hold potable water designated for membrane module maintenance and recovery cleaning purposes. The two CIP storage tanks provide a storage capacity of 16,200 gallons per tank.
Additionally, the water serves for the foam control system, which uses a spray system to reduce biological foaming in the basins.
Water is extracted from each CIP tank through two pumps: one for the CIP cleaning process and another for supplying the foam spray system. For each of these systems, there is one primary pump and one backup pump (for a total of four pumps), allowing them to alternate to reduce wear and provide redundancy. Table 4-10 summarizes the major equipment associated with the CIP storage tanks and foam spray system. 311

4.3.10 Sludge Handling System
WAS is thickened, aerobically digested, and dewatered prior to being hauled offsite for disposal. Two gravity belt thickeners (GBTs) can receive WAS from the WAS pumps. Polymer is added to enhance the thickening process.
Three 58-foot by 38-foot by 23-foot aerated sludge digestion basins receive flow from the WAS pumps installed in the MLSS recirculation channel. The aerobic digesters provide stabilization and storage of waste sludge prior to thickening, dewatering, and disposal. The key equipment components for each digester include fine bubble diffusers, sludge withdrawal pumps, rethickening pumps, and blowers. Rethickening pumps can circulate sludge from the digesters back through the gravity belt thickeners as needed.
During dewatering operations, the digested sludge is extracted from the aerated sludge storage basins and directed to the screw press via the screw press feed pumps. Polymer is added to enhance dewatering within the screw press.
The sludge is released onto a conveyor system and deposited into a roll-off bin, serving as on-site storage for the sludge until it is transported away for disposal. Table 4-11 summarizes the major equipment associated with solids handling system.

5.0 EVALUATION CRITERIA
This section provides an overview of the evaluation criteria used to analyze the City’s existing collection system including gravity sewer pipes, lift stations, and force mains.
5.1 Gravity Collection System Criteria
The City has adopted design standards and specifications for sewer collection system improvements. These design standards, along with industry-accepted design criteria for gravity pipelines, lift stations and force mains, were utilized (when feasible) to evaluate the ability of the City’s existing sewer infrastructure to meet existing and future flows. Table 5-1 provides a summary of the City’s design standards for sewer improvements.

EVALUATION CRITERIA
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 5-2
5.2 Lift Station Criteria
The following criteria were used to evaluate the capacity of the City’s existing lift stations under existing and future flow conditions.
5.2.1 Pump Capacity
It is recommended that lift stations are designed with a minimum of two pumps, such that the pumping system can serve the full design flow with the largest pump offline, to provide full redundancy if one pump fails or requires service, to alternate pump cycles to minimize wear on the pump components, and to provide supplemental pumping capacity to convey instantaneous peak flows. Each pump should be sized to convey the peak hour flow entering the wet well.
5.2.2 Force Mains
Force mains were analyzed to determine if they are properly sized to convey the lift station pumped flow, while maintaining minimum pipeline velocities to re-suspend solids and provide pipeline cleaning. It is recommended that lift station force mains convey minimum velocities of 3.5 to 6 feet per second (fps) with maximum velocities less than 10 fps to minimize head loss and potential for surge events.
5.3 WRF Criteria
Design criteria used to evaluate the WRF treatment processes are included in Section 9. 318

HYDRAULIC COMPUTER MODEL
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 6-1
6.0 HYDRAULIC COMPUTER MODEL
This section provides an overview of the collection system hydraulic model developed for this project to analyze the ability of the existing system to serve existing and future flows.
6.1 Model Development
MKN developed a hydraulic model using Bentley SewerCAD CONNECT Edition Version 10 (SewerCAD) hydraulic modeling software to simulate the operation of the gravity collection system. SewerCAD utilizes Manning’s equation for open channel flow, and the Hazen-Williams formula for pressure pipes (lift station force mains). The hydraulic model was run under steady state conditions using a backwater analysis. This type of analysis starts at the collection system outlet locations (the WRF in this instance) with an assigned outlet condition (either free discharge, submerged, or tailwater control). From the outlet location SewerCAD proceeds in an upstream direction performing the hydraulic analysis. A representative model of the existing collection system was developed using the following information:
❑ City’s existing sewer collection system AutoCAD file (pipelines, manholes, lift stations, and cleanouts) that provided the following information: Pipeline alignment, diameter, material, and length ❑ As-built plans
6.1.1 Sewer Flow Allocation
To distribute existing and future flows throughout the collection system model, baseline flow conditions were established as described in Section 3. Water demands within the Study Area were converted to sewer flows based on reduction factors and verified with flow monitoring data.
Each parcel within the Study Area was assigned an existing wastewater flow and future wastewater flow (when applicable). Each parcel was also associated with the closest manhole that it was assumed to flow to. Each manhole imported into the hydraulic model was “loaded” with the existing and future sewer flows from the upstream parcels entering the manhole (i.e. the manhole’s sewershed).
Figure 6-1 shows a sample of the sewersheds that were developed for loading existing and future flows into the hydraulic model. Major trunk pipelines throughout the City and other critical areas were included in the hydraulic model and are shown on Figure 6-2.

6.1.3 Model Settings
With the collection system network configured, existing and future flows were imported into SewerCAD and the following modeling parameters were configured:
❑ All hydraulic simulations were completed under the following:
o Steady state time analysis – Single instantaneous analysis o Analysis calculation method – Gradually Varied Flow with Convex Routing (GVF-Convex Solver) ❑ The following Mannings n friction coefficients were used for gravity pipelines:
o All existing pipes: 0.013
o New pipes: 0.011
6.2 Hydraulic Model Flow Validation
As described in Section 3.4, MKN used City water usage data and WRF influent treatment flows from 2020 to 2022 to estimate existing flow conditions within the hydraulic model. These initial flow estimates were verified using the newly acquired flow monitoring data.

7.0 HYDRAULIC ANALYSIS – EXISTING CONDITIONS
This section summarizes the hydraulic evaluation of the existing collection system to serve existing flows within the Study Area.
7.1 Gravity Collection System Hydraulic Analysis
7.1.1 Evaluation Overview
The collection system was evaluated using the design criteria defined in Section 5 under PHDWF and PHWWF flow conditions and recommendations were made for pipes found to be deficient.
The existing gravity collection system includes over 59 miles of gravity sewer pipe ranging from 4-inch to 42-inch in diameter. As described in Section 6, MKN developed a hydraulic model in Bentley’s SewerCAD using information from the 2012 WWMP and the City’s existing collection system AutoCAD file to evaluate the City’s collection system.
Only pipe segments along major trunk sewer mains were evaluated, amounting to approximately 11 miles or 18% of the system (Figure 6-2). The pipe segments selected for the evaluation were consistent with the pipe segments selected for analysis in the previous 2012 WWMP.
The hydraulic evaluation of the gravity collection system includes the pipeline sizes, slopes, and downstream restrictions. The ratio of the depth of wastewater (d) to the diameter of the pipe (D) is a typical measure of the hydraulic capacity in gravity pipelines. Pipes were considered deficient if the pipe’s d/D exceeded the following PHWDF and PHWWF conditions:
❑ Peak Hour Dry Weather Flow (PHDWF)
o For a pipe 12 inches or less, a d/D of 50 or greater
o For a pipe greater than 12 inches, a d/D of 67 or greater ❑ Peak Hour Wet Weather Flow (PHWWF)
o For all pipe diameters, a d/D of 75 or greater
7.1.2 Existing Flows Hydraulic Model Evaluation Results Figure 7-1 and Figure 7-2 provide an overview of model results showing pipeline velocities during existing PHDWF and PHWWF conditions, respectively. Based on model results, approximately 89% of the modeled gravity pipelines achieved self-cleaning velocities equal to or greater than 2 feet per second during PHDWF conditions. During PHWWF conditions, approximately 97% of the modeled gravity sewer pipelines achieved self-cleaning velocities equal to or greater than 2 feet per second. These self-cleaning velocities are considered satisfactory, and no gravity pipeline improvements were recommended based on insufficient velocities.
Table 7-1 provides a summary of the existing gravity collection system pipeline deficiencies based on the evaluation criteria defined in Section 5. Existing system deficiencies were assigned a deficiency number, using “EX” to 325

Based on the existing hydraulic model evaluation, there are approximately 50 pipelines that exceed the d/D capacity criteria under existing PHDWF and/or PHWWF conditions.
Additionally, seven pipeline d/D deficiencies are resolved once downstream conditions are improved through recommended pipeline upgrades. Eight of the pipeline d/D deficiencies are within 5% of the design criteria, and improvements were not recommended for the marginal exceedance of the design criteria. Figure 7-3 provides an overview of existing PHDWF pipeline d/D deficiencies and Figure 7-4 provides an overview of existing PHWWF pipeline d/D deficiencies.

HYDRAULIC ANALYSIS – FUTURE CONDITIONS
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 9-1
9.0 HYDRAULIC ANALYSIS – FUTURE CONDITIONS
This section summarizes the hydraulic evaluation of the existing collection system to serve Near-Term and Ultimate flows.
9.1 Gravity Collection System Hydraulic Analysis
9.1.1 Evaluation Overview
MKN evaluated the existing collection system against Near-term and Ultimate flows as defined in Section 3. The future flow scenarios included the following development within or adjacent to the City’s SOI:
❑ Near-Term Flows
o Approved / Pending Projects
o East Area 1 Specific Plan
o East Gateway Specific Plan
❑ Ultimate Flows
o Vacant Residential Sites
o Vacant Commercial Sites
o Adams Canyon Expansion Area
o Fagan Canyon Expansion Area
o East Area 3 Expansion Area
o West Area 2 Expansion Area
Gravity collection system deficiencies were determined based on a hydraulic evaluation of pipeline sizes, slope, and downstream restrictions. Pipes were considered deficient if the pipe’s d/D was greater than the following for PHDWF and PHWWF conditions:
❑ Peak Hour Dry Weather Flow (PHDWF)
o For a pipe 12 inches or less, a d/D of 50 or greater
o For a pipe greater than 12 inches, a d/D of 67 or greater ❑ Peak Hour Wet Weather Flow (PHWWF)
o For all pipe diameters, a d/D of 75 or greater
9.1.2 Near-Term Flows Hydraulic Model Evaluation Results For near-term flows, MKN assumed that all the pipeline recommendations identified in Table 7-2 were completed prior to conducting the hydraulic evaluation. Figure 9-1 and Figure 9-2 provide an overview of gravity pipeline velocities resulting from the model under near-term PHDWF and PHWWF conditions, respectively. 345

HYDRAULIC ANALYSIS – FUTURE CONDITIONS
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 9-4 Based on model results, approximately 93% of the modeled gravity sewer pipelines within the City’s SOI will achieve self-cleaning velocities equal to or greater than 2 feet per second during PHDWF conditions. During PHWWF conditions, approximately 97% of the modeled gravity sewer pipelines within the City’s SOI will achieve self-cleaning velocities equal to or greater than 2 feet per second. These self-cleaning velocities are considered satisfactory, and no gravity sewer improvements are recommended based on insufficient velocities.
Table 9-1 provides a summary of the near-term gravity collection system pipe deficiencies based on the design criteria defined in Section 5. System deficiencies were assigned a deficiency number using “NT” to designate the near-term flow condition (i.e. NT-1).
Based on the near-term hydraulic model evaluation, there are 12 pipelines that exceed the d/D design criteria under near-term PHDWF and PHWWF conditions and are considered deficient. Ten pipeline d/D deficiencies that were within 3% of the design criteria were not recommended for capital improvement in the Near-Term scenario.
Figure 9-3 provides an overview of PHDWF pipeline d/D deficiencies and Figure 9-4 provides an overview of PHWWF pipeline d/D deficiencies for the near-term scenario. These results assume the pipeline improvements identified to address deficiencies under existing flow conditions (Table 7-2) were completed.
Table 9-2 provides a summary of the recommended improvements to address capacity deficiencies associated with near-term PHDWF and PHWWF conditions (as described in Table 9-1).
9.1.3 Ultimate Flows Hydraulic Model Evaluation Results For ultimate flows, MKN assumed that all the pipeline recommendations identified in Table 7-2 and Table 9-2 were completed prior to conducting the hydraulic evaluation. Figure 9-5 and Figure 9-6 provide an overview of typical gravity pipeline velocities during ultimate PHDWF and PHWWF conditions, respectively. Based on model results, approximately 94% of the modeled gravity sewer pipelines within the City’s SOI will achieve self-cleaning velocities equal to or greater than 2 feet per second during PHDWF conditions. During PHWWF conditions, approximately 97% of the modeled gravity sewer pipelines within the City’s SOI will achieve self-cleaning velocities equal to or greater than 2 feet per second. These self-cleaning velocities are considered satisfactory, and no gravity sewer improvements are recommended based on insufficient velocities.
Table 9-3 provides a summary of the ultimate gravity collection system pipe deficiencies based on the design criteria defined in Section 5. System deficiencies were assigned a deficiency number using “ULT” to designate ultimate flow condition (i.e. ULT-1).
Based on the ultimate hydraulic model evaluation, there are 50 pipelines that exceed the d/D design criteria under ultimate PHDWF and/or PHWWF conditions and are considered deficient. Fourteen pipeline d/D deficiencies that were within 5% of the design criteria were not recommended for capital improvement. Additionally, ten pipeline d/D deficiencies are addressed once downstream conditions are improved through larger diameter pipelines.

10.0 WATER RECYCLING FACILITY EVALUATION
This section summarizes the existing flows and loads to the WRF, condition assessment of existing facilities, and evaluation of capacity to serve existing and future flows and loads.
10.1 Historical Flows and Loadings
The following provides analysis of historical flows and influent loadings, influent concentrations, and existing effluent requirements and quality observed at the WRF.
10.1.1 Historical Influent Loading
At the WRF, influent organic and solids loading are calculated using monthly grab measurements of five-day biochemical oxygen demand (BOD5) and Total Suspended Solids (TSS), mandated by Monitoring and Reporting Program (MRP) No. CI-9259. While the WRF has an effluent limit of 10 mg/L for Ammonia as nitrogen + nitrate as nitrogen + nitrite as nitrogen, it has not historically been required for measurement in plant influent.
The raw influent wastewater characteristics used in the original design for the WRF is summarized in Table 10-1.
These values were obtained from the Trussell Technologies, Inc., Evaluation of Biological Design and Process Sizing Technical Memorandum (2008) which is attached as Appendix F.
Table 10-1: 2008 Raw Influent Design Criteria
Parameters Unit Raw Influent
Minimum Temperature °C 19
Biochemical Oxygen Demand (BOD) mg/L 320
Total Suspended Solids (TSS) mg/L 210
A summary of the influent monitoring data from 2014 to 2023 is presented below in Table 10-2 and Table 10-3.
These records indicate the plant encountered its highest BOD5 concentration in 2022 and its highest TSS concentration in 2019. The data also show that for every year except 2014 and 2022, the BOD5 annual average concentrations were above the original design value of 320 mg/L. Similarly, all TSS annual average concentrations were above the original design value of 210 mg/L. The maximum month values for both constituents are substantially above the design criteria.

WATER RECYCLING FACILITY EVALUATION
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 10-3 WRF monitoring data from 2019 through 2023 was used to estimate the BOD5 and TSS loadings as presented in Table 10-4 below. Because wastewater in a community can change over time, with growth and other changes within a collection system, only the most recent full four years of data was used to estimate existing conditions. The loads are calculated by multiplying the relevant flow rate by the concentration and the constant of 8.34 lbs/gal. The calculated maximum month concentrations (mg/L) are acquired by dividing the maximum month load (ppd) by the maximum month flow (MGD) times 8.34 lbs/gal.

To develop wastewater loading projections, per capita loading values were calculated from the existing loading data in Table 10-4 for 2019 through 2023. The projections are developed by dividing the loads by the population of each year mentioned. Population estimates were acquired from the State of California Department of Finance demographics estimate data. Loading per capita values are summarized in Table 10-5.

Notes:
1. Limit is based on best professional judgement. Limits adopted by this Regional Board exist in the permits for tertiary-treated wastewater treatment plants
2. Limit is based on secondary treatment requirements, 40 C.F.R. section 133.102
3. Limit is based on the Load Allocations for nonpoint sources set forth in the Santa Clara River Nitrogen Compounds TMDL, Resolution No. 2003-011
4. Limit based on Basin Plan Groundwater Quality Objective MKN reviewed the historical effluent quality based on annual reports from 2019 to 2023 provided by the City.
During this time, the exceedances that occurred were for chloride, boron and ammonia-n + nitrate-n + nitrite-n, as shown in Appendix F. The WRF treatment equipment is unable to reduce chlorides. The City is planning improvements to address this and is operating the WRF in compliance with CDO No. R4-2018-0023-A01 which provides a ten-year timeline by which the City must come into compliance with the chloride effluent limit of 110 mg/L. The CDO outlines a schedule with interim milestones and effluent limits. To meet the chloride effluent limit, the AWTF will be constructed at the WRF as discussed in Section 4.3.14. 377

10.3.1 Flow and Loading Conditions
Existing flows and loading conditions were developed as described in Sections 3.1 and 10.1. Future BOD5 and TSS loadings were projected for near-term and ultimate conditions using two methods:
❑ Projecting future loads using existing peak concentrations and applying to future flows; and ❑ Applying three-year average loads (per capita) calculated in Table 10-5 to future population projections These two methods are identified in Table 10-8 and Table 10-9 for near-term and ultimate loads.

10.3.2 Influent Lift Station
The influent lift station at the WRF was designed to accommodate a PHWWF capacity of 17.0 MGD with one pump out of service. Presently, the PHWWF is approximately 7.7 MGD. Projections suggest that in the near-term and under ultimate future conditions, the PHWWF may increase to 9.0 MGD and 10.6 MGD, respectively, factoring in expected growth. Given the design capacity of the influent lift station, the existing facility can handle existing, near-term, and ultimate future conditions.

As seen above, the coarse screens, grit removal system and fine screens (both trains in service) have the ability to meet existing and future peak hour flow demands. Replacing the existing fine screens with higher capacity units is recommended to meet future demands with one unit out of service, providing redundancy. The fine screens are necessary to protect the membranes in the MBR Basins from damage.
10.3.4 Primary and Secondary Equalization Basins
The WRF's two EQ basins function in series, collectively providing a storage capacity of 1.05 million gallons. They are designed to provide two hours of equalization storage at a PDF of 10.4 MGD. Basin size is summarized below:
Table 10-15: Equalization Basins
Equalization Basin Size (L x W x H in ft) Storage (gals) Primary 45 x 40 x 24 281,000
Secondary 118 38 x 24 771,400
Currently the EQ basins have sufficient storage to meet existing and future demands as shown in Table 10-16.
However, City staff has noted that adding an additional EQ basin to the WRF would provide additional emergency storage.

MKN used data from Table 10-5 to estimate the parameters used in Table 10-18. Specifically, averages from 2021- 2023 for calculated maximum month concentrations for BOD5 and TSS were used in the estimation. As recommended in the Trussel TM, MKN reduced the calculated average maximum month values for BOD5 by 10% and TSS by 20% to account for impact of upstream screening processes. Comparing the values calculated for the existing and future flow conditions for BOD5 and TSS in Table 10-8 to the reduced values used in our MBR design evaluation above, the percent differences are approximately 7% and 19% respectively for BOD5 and TSS. TKN was estimated assuming a ratio of BOD5 to TKN of 6 to 1 since influent nitrogen concentrations were not available.
Other rations and coefficients used in estimating other pertinent influent parameters used in the model are presented in Table 10-19.

Fractions/Coefficients Value Used Parameter Acquired Units VSS/TSS Ratio 0.79 VSS = 260 mg/L
COD/VSS Ratio 3.3 COD = 857 mg/L
Ammonia/TKN Ratio 0.6 Ammonia = 42 mg/L
Using parameters discussed above, MKN determined that the full MBR process meets existing, near-term, and ultimate conditions with one treatment train out of service. For the anoxic basins, it was determined that for all conditions and with one full process train out of service, the existing system has the ability to handle the anticipated flows and loads.

There are a total of four aeration blowers for the aeration tanks (3 running and one in standby). Each blower output supplied is 1,750 SCFM. The total air flow supplied by the three active blowers is approximately 5,250 SCFM. The model indicates a required air flow of 5,920 SCFM for the ultimate-term development MMF. Therefore, it appears the current blowers do not meet the ultimate buildout conditions. An additional blower is recommended to be installed for redundancy.
There are three blowers dedicated for membrane scouring, (two running and one in standby) each supplying 4,700 SCFM of air. MKN found that the required scouring air flow rate under all flow conditions can be met by one blower (Table 10-21). This also confirms that the two running blowers can meet the requirements and there is no need to add additional membrane blowers.

MKN also evaluated maximum membrane flux capacity. The existing Koch Puron PSH-1800-36-BB membrane modules were installed in 2022 to replace the membrane cartridges installed when the plant was originally constructed in 2010. Four modules were installed in each basin and each module included 36 rows of membrane fibers, with the ability to add another eight rows to increase capacity in the future.
The goal is to stay with a peak flux rate of 15 gpd/SF at typical wastewater temperatures with all basins in service.
This allows the system to operate temporarily at a maximum flux rate of 19 gpd/SF with one basin out of service, per the design specifications developed for the 2022 membrane replacement project completed by the City. The 391

As shown above, the maximum membrane flow rate (for a maximum flux rate of 15 gpd/SF) is not exceeded until ultimate PDF. Capacity could be increased by utilizing the available space within the current membrane basins.
Work will include extending the MBR feed channels and placing additional equipment such as MBR feed pumps, blowers, permeate pumps, piping and ancillary equipment. Building out the empty membrane basins, would increase capacity above the ultimate PDF.
10.3.6 UV Disinfection System
The UV disinfection system has a total of two channels with five banks per channel. The capacity was assessed based on the design peak hour flow capacity of 10.4 MGD with 4 banks operating and one bank out of service in each channel. As shown in Table 10-23, the system does not have the capacity to handle the ultimate future loading conditions unless all five banks are in service. As presented in Table 10-24 the system with all five banks operating can meet all existing and future flow conditions. Since peak hour is an extreme event, and the current effluent disposal permit does not require redundancy in disinfection, no expansion is necessary in the immediate future.

WATER RECYCLING FACILITY EVALUATION
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 10-21 solids, assuming WAS flow is 1.2% solids. In 2023, the WRF disposed of approximately 6.3 million pounds of sludge, or an average of 720 lbs per hour assuming 24 hour per day operation (or 14 hours per day, five days per week at the solids handling capacity of 1,593 pounds per hour). These calculations were developed assuming only one thickener is in operation to provide redundancy. Future loads to the sludge thickener are expected to increase by 17% at near-term and 38% at ultimate conditions, respectively. This will require operating one thickener either an extra day each week at near-term conditions and increasing operating time to 20 hours per day, five days per week at ultimate conditions.
10.3.8 Aerobic Sludge Digesters
The three aerobic sludge digesters have a combined capacity of approximately 1.15 MG. They are designed to provide a solids retention time (SRT) of 18 days at 30° C (86° F), which would achieve over 50% VSS reduction per the Trussell Technologies, Inc., Evaluation of Biological Design and Process Sizing Technical Memorandum (2008).
At ultimate conditions, since the WAS rate is anticipated to increase 38% in proportion to future loads, the future loading rate to the thickeners would increase from 50,000 gpd to approximately 62,000 gpd. Assuming the thickeners increase solids from 0.85% to 2.5%, this would reduce the thickened WAS rate to approximately 21,080 gpd and provide a SRT of 55 days with all three digesters in service or 36 days with two digesters in service. This is adequate through ultimate conditions.
10.3.9 Sludge Dewatering Screw Press
The existing screw press at the WRF is used for sludge dewatering, the final step in the sludge handling process. It is designed to have a hydraulic capacity of 92 GPM and a solids handling capacity of 918 pounds per hour. The screw press is designed to produce dewatered sludge with a solids concentration of approximately 22%. It was also designed to operate five days a week, 8 hours per day (40 hours per week). Per plant operators, the current screw press is operated 5 to 7 days a week for 20 to 24 hours per day (100 to 168 hours per week).
Operations staff have noted the original design underestimated the amount of solids being produced at the WRF.
As noted in Section 10.3.7, in 2023, the WRF disposed of approximately 6.3 million pounds of sludge, or an average of 720 lbs per hour assuming 24 hour per day operation (or 19 hours per day at the solids handling capacity of 918 pounds per hour). It is recommended the WRF install a second screw press, to provide redundancy and reduce wear on the screw press, especially given the additional usage anticipated in the future. 393

11.0 CAPITAL IMPROVEMENT PLAN
This section provides the recommended Capital Improvement Plan (CIP) for the City’s wastewater collection system, treatment, and disposal systems based on the evaluations and findings of this Master Plan. Prior to the implementation of the recommended projects, the City should consider conducting a preliminary engineering evaluation for each project to refine the scope, assess feasibility and possible alternatives, and develop a more detailed cost estimate.
11.1 Capital Improvement Plan Development
The CIP serves as a fundamental pillar for strategic planning for collection system assets, optimization of system performance, and meeting the evolving needs of wastewater customers. Through planning and analysis, the CIP sets the stage for budgeting capital investments that will result in improved reliability and system efficiency.
11.1.1 Project Identification
Recommended projects were identified through the following evaluations included in the Master Plan:
❑ Collection System Hydraulic Analysis: The hydraulic analysis identified deficiencies in the existing wastewater collection system to serve existing and future flow (near-term and ultimate) conditions during ADF conditions. Recommended improvements include replacement of existing deficient pipelines with larger diameter pipes and/or directing future flows to locations within the collection system with available hydraulic capacity.
❑ WRF Evaluation: The WRF evaluation assessed the adequacy of the existing treatment processes, hydraulic capacity of plant equipment, and the disposal system to serve existing and future flow and load (near-term and ultimate) conditions.
❑ Condition Assessment: A condition assessment of the City’s existing lift stations and WRF was performed to review previous recommendations and identify observed physical deficiencies. As part of this effort, MKN visited the existing lift stations and WRF site to document the condition of the existing system and interview the plant operators. Based on the condition assessment, MKN developed a comprehensive list of recommended improvements to address observed deficiencies.
11.1.2 Basis of Costs
To develop cost estimates for the proposed improvements, MKN utilized the Association for Advancement of Cost Estimating International (AACE) guidelines for cost estimating practices and classification. The Cost Estimate Classification System – As Applied in Engineering, Procurement, and Construction for the Process Industries (AACE International Recommended Practice No. 18R-97) provides guidelines for applying the principles of estimate 395

Notes:
1. The state of process technology and availability of applicable reference cost data affect the range markedly. The +/- value represents typical percentage variation of actual costs from the cost estimate after application of contingency (typically at a 50% level of confidence) for given scope.
2. If the range index value of “1” represents 0.005% of project costs, then an index value of 100 represents 0.5%. Estimate preparation effort is highly dependent upon the size of the project and the quality of estimating data and tools.
The cost estimates developed for this Master Plan are considered Class 4 Estimates, which is defined by AACE International as follows:
Class 4 estimates are generally prepared based on limited information and subsequently have fairly wide accuracy ranges. They are typically used for project screening, determination of feasibility, concept evaluation, and preliminary budget approval. Typically, engineering is from 1% to 15% complete and would comprise at a minimum the following: plant capacity, block schematics, indicated layout, process flow diagrams (PFDs) for main process systems, and preliminary engineering process and utility equipment lists. Class 4 estimates are prepared for a number of purposes, such as but not limited to, detailed strategic planning, business development, project screening at more developed stages, alternative scheme analysis, confirmation of economic and/or technical feasibility, and preliminary budget approval to proceed 396
DRAFT
CAPITAL IMPROVEMENT PLAN
City of Santa Paula Wastewater Collection System and Water Recycling Facility Master Plan Page | 11-3 to next stage. Typical accuracy ranges for Class 4 estimates are -15% to -30% on the low side, and +20% to +50% on the high side, depending on the technological complexity of the project, appropriate reference information, and the inclusion of an appropriate contingency determination. American National Standards Institute (ANSI) Standard Reference Z94.2-1989 references this class as a “Budget Estimate”, with an accuracy range between -15% to +30%.
The cost estimates for this Master Plan are anticipated to be within an accuracy of -20% to +30%. The accuracy of the estimates reflects the level of confidence that an estimate will be near the actual project cost. The accuracy of the estimates should not be confused with the application of a project contingency (which is applied for unknown or unforeseen project conditions).
11.1.3 Cost Estimation
The opinions of probable cost prepared by MKN represent our judgment and are supplied for the general guidance for the City. Since MKN has no control over the cost of labor and material, or over competitive bidding or market conditions, MKN does not guarantee the accuracy of such opinions as compared to contractor bids or actual project costs. For each project identified, cost opinions were generated based on the following assumptions:
❑ Full capitalization inclusive of engineering, design, permitting, and construction administration / management
❑ Costs derived from similar infrastructure projects, with adjustments for inflation, size, complexity, and location
❑ Construction cost opinions were developed in March 2024. Use 20-Cities Engineering News-Record (ENR) Construction Cost Index (CCI) March 2024 = 13532.01 to escalate estimated cost to present value
❑ Cost opinions are “planning-level” and may not fully account for site-specific conditions or design decisions
❑ Construction contingency was estimated at 30 percent of total construction costs ❑ Engineering design services was estimated at 15 percent of total construction costs ❑ Project administration and construction management together was estimated at 15 percent of total construction costs
❑ All costs rounded to the nearest $1000
Table 11-2 contains the unit construction costs for gravity collection system improvements and factors for estimating the non-construction costs associated with infrastructure improvement projects such as engineering design, project administration, and contingency to arrive at a total project cost. 397

11.1.4 Project Prioritization and Scheduling
Each project was evaluated and ranked to determine the significance of the improvement and provide the City with a systematic method to assign priorities for each project. For each collection system pipeline, lift station, and WRF project, a priority point scale from 1 to 4 was assigned based on whether it resolved an existing capacity deficiency, near-term capacity deficiency, improved system efficiency/operations, or resolved an ultimate (build-out) capacity deficiency. The priority scale and scheduling projects is summarized in Table 11-3.
Table 11-3: Project Ranking
Priority Description
1 Required to resolve existing significant capacity or condition-based deficiency and recommended for implementation within the next 1 - 3 years from the adoption of the Master Plan 2 Required to resolve less significant existing capacity or condition-based deficiency and recommended for implementation within the next 3 - 5 years from the adoption of the Master Plan 3 Required to resolve near-term capacity deficiency and recommended for implementation within the next 5 - 10 years from the adoption of the Master Plan

During the flow monitoring study, the average day water demand was 2.72 MGD and the average day flow to the WRF was 2.02 MGD, resulting in an average return factor of 74%, which is slightly lower than the average return factor of 86% from 2020 to 2022. For validating the preliminary return factors, MKN reduced the return factors for all land uses proportionally by 12%. Table 1 provides the preliminary wastewater return factors adjusted proportionally for validation with the flow monitoring study.

Notes:
1. Potable water usage was calculated using a three-year average from 2020 to 2022 water billing data. Water usage that did not result in return wastewater flows was not included in this average (ex: hydrant testing, landscaping-specific meters, water losses, etc.)
2. Actual existing average daily flow calculated from influent WRF data from 2020 to 2022 Table 2 through Table 5 provide a summary of the estimated average day water demand and average day flow within the FM01, FM02, FM03, and FM04 sewersheds during the flow monitoring study. 539

Estimated ADF for flow meter basins FM01 and FM04 were within approximately 11% of the measured flows, which are within an acceptable range for validation purposes. However, FM02 and FM03 had large discrepancies at approximately 50% and 45%, respectively. Possible explanations could include discrepancies with the flow meter at the WRF or pipeline connections throughout the collection system that may be directing flow to other portions of the collection system not measured by the flow meters.

WASTE DISCHARGE REQUIREMENTS
ISSUED TO
CITY OF SANTA PAULA
(SANTA PAULA WATER RECYCLING FACILITY)
The California Regional Water Quality Control Board, Los Angeles Region (Regional Water Board) finds:
PURPOSE OF ORDER
1. The City of Santa Paula (City or Discharger) is the owner of the Santa Paula Water Recycling Facility (SPWRF), a Publicly-Owned Treatment Works (POTW), located at 920 Corporation Street in Santa Paula, California (Figure 1). The SPWRF, currently operated by Ventura Regional Sanitation District, discharges tertiarytreated wastewater to groundwater via three percolation ponds adjacent to the facility.
2. The City was previously regulated under Waste Discharge Requirements (WDRs) contained in Order No. R4-2007-0028, adopted by this Regional Board on May 3, 2007. The Regional Board amended Order No. R4-2007-0028 three times as follows:
A. Order No. R4-2010-0074, adopted by this Regional Board on May 6, 2010, required that effluent discharged to percolations ponds shall not exceed 2.6 million gallons per day (MGD).

2 3. On October 1, 2015, the Regional Board directed the City to submit a Report of Waste Discharge (ROWD) for application of renewal of the City’s WDRs to discharge treated wastewater from the SPWRF to the percolation pond. On December 5, 2015, the City filed its ROWD for the SPWRF.
4. To verify the information provided in the ROWD, Regional Board staff conducted inspections of the SPWRF on December 8, 2015 and December 28, 2016, including the wastewater treatment processes, percolation ponds, and groundwater monitoring wells.
5. The purpose of this Order is to renew WDRs for the City’s SPWRF. This Order includes updates to effluent limitations, groundwater limitations, and Monitoring and Reporting Program (MRP) CI No. 9259 to ensure that the City’s discharge of waste complies with water quality objectives set forth in the Water Quality Control Plan for the Los Angeles Region: Basin Plan for the Coastal Watersheds of Los Angeles and Ventura Counties (Basin Plan) and is protective of beneficial uses.
BACKGROUND
6. Before 2010, the City’s wastewater was treated at the Santa Paula Wastewater Reclamation Plant (Plant), which discharged the treated wastewater to the Santa Clara River. That discharge was regulated by a National Pollutant Discharge Elimination System (NPDES) permit. Due to the age of the Plant, which was built in 1939, the City was unable to comply with the effluent limitations for biological oxygen demand (BOD), total suspended solids (TSS), turbidity, bacteria, residual chlorine, nitrate-nitrite, sulfate, and toxicity, as set forth in its NPDES permit. More than 3,000 violations at the Plant lead the Regional Board to engage in settlement discussions with the City, resulting in a Stipulated Consent Judgment and Final Order in 2007.
The City chose to build a new treatment plant, the SPWRF, to discharge to groundwater through percolation ponds. The City was required to complete construction of the new SPWRF by September 15, 2010 and be in full compliance with WDRs set forth in Order No. R4-2007-0028 by December 15, 2010.
7. Construction of the SPWRF began in July 2008 and was completed in December 2009. The SPWRF began accepting partial flow in April 2010 and then accepted all flow from the City in May 2010. The Plant built in 1939 was thereafter decommissioned.
8. According to the United States Census Bureau, approximately 19% of the population in the City have income levels below the poverty line, and approximately 25% of area in the City is categorized as a disadvantage community (less than 80% of the State's median household income) or a severely disadvantaged community (less than 60% of the State's median household income). The average sewer fee assessed for a single family was about $88, based on the City’s 2014 Water and Sewer Rate Study Results.

3 9. Drinking water supplied to the City is produced from deep wells including Well 1-B, Well 11, Well 12, Well 13, and Well 14, which are owned and operated by the Water Division of the City and produce up to 10.6 MGD. Water produced at all five wells between 2010 and 2020 complied with all primary state and federal drinking water standards. Table 1 summarizes drinking water test results for total dissolved solids (TDS), sulfate, chloride, and boron from the City’s 2010-2020Annual Water Quality Reports, as compared to the groundwater quality objectives (GQOs) set forth in the Basin Plan.

CURRENT FACILITY AND TREATMENT PROCESS DESCRIPTION
10. SPWRF and Vicinity
A. The SPWRF (34o 19’ 56.3” N, 119o 04’ 57.2” W) is sited on a 50-acre parcel along Calpipe Road and Todd Lane in Santa Paula, California (Figure 1). The SPWRF is approximately 1,200 feet southeast of Highway 126, approximately 1,000 southwest of Shell Road, and approximately 1,300 feet northwest of the Santa Clara River.
B. The SPWRF is located over the Santa Clara-Santa Paula Groundwater Basin (DWR Basin No. 4-4) (Figure 2).

4 A. The SPWRF treats wastewater generated within the City and is designed for a flow of 4.2 MGD. Based on the discharge records between July 2010 and June 2017, the monthly average effluent discharged from the SPWRF ranged between 1.36 and 2.44 MGD, with an average of 1.86 MGD. The monthly average effluent discharge flow rates between February 2018 and December 2021 ranged from 1.03 to 3.4 MGD, with an average of 1.86 MGD.
B. The wastewater treatment process at the SPWRF (See Figure 3 for process flow schematic) consists of preliminary treatment (coarse and fine mechanical screening and grit removal at the Influent Lift Station), flow equalization (two flow equalization tanks), secondary treatment (three aeration tanks with nitrification and denitrification activated sludge), tertiary treatment (six membrane bioreactors, providing further carbonaceous oxidation, nitrification/denitrification and solids removal to meet the limits of the WDRs), and disinfection (UV). Treated and disinfected effluent is discharged to three percolation ponds (Figure 5). The returned activated sludge is treated at two of three aerobic digesters (one aerobic digester is for backup) after being thickened at two thickeners. The solids generated at the aerobic digesters receive final dewatering at the screw dewatering press. Final solids are hauled by Synargro to their South Kern Compost Manufacturing Facility where they are composted to the United States Environmental Protection Agency (USEPA) Class A reuse standards for agricultural reuse.
C. To address levels of chloride in the effluent, an advanced treatment system, consisting of reverse osmosis (RO), will be constructed at the SPWRF, which will be designed to reduce the chloride concentration in the effluent to 110 milligrams per liter (mg/L) or less. The RO system will consist of nanofiltration and RO units to reduce effluent chloride concentrations followed by a RO brine concentrator (Figure 4).
D. The City owns and operates the sewer collection system, which conveys domestic, commercial, and industrial wastewater to the SPWRF. Two industrial users within the City are Aurora Casting (metal foundry) and Saticoy Lemon (lemon packing house). The City is required to implement a Pretreatment Program and to comply with requirements for operation and maintenance of the sewer collection system. The City has been implementing an industrial wastewater Pretreatment Program for the SPWRF, which has been approved by the USEPA and the Regional Board.
E. Percolation Ponds
i. The three percolation ponds were built on approximately 34 acres of agriculture land (Figure 5) and are located along Todd Lane in the Santa Clara-Santa Paula Groundwater Basin area.
ii. The Regional Board classified the discharge to the percolation pond as a discharge of treated wastewater to land that is subject to WDRs. 547
