NO. All APPROVED BY: Beth Gentry, Engineering Manager Michael Long, Chief, Engineering Jose Martinez, General Manager SUBJECT: Award of a Professional Engineering Services Agreement for the Planning Study of the Joint Sweetwater Authority – Otay Water District Recycled Water Intertie Project GENERAL MANAGER’S RECOMMENDATION: The Otay Water District (District) Board of Directors (Board) award a professional Engineering Services Agreement to Carollo and authorize the General Manager to execute a Professional Engineering Services Agreement with Carollo to conduct a Planning Study of the Joint Sweetwater Authority (SWA) – Otay Water District (OWD) Recycled Water Intertie Project in an amount not-to-exceed $305,470(see Exhibit A for Project location). COMMITTEE ACTION: Please see Attachment A. PURPOSE: To obtain Board authorization for the General Manager to enter into a professional engineering services agreement with Carollo for planning support for the Joint SWA-OWD Recycled Water Intertie Project in an amount not-to-exceed $305,470. AGENDA ITEM 3 2 ANALYSIS: On August 11, 2022, two Board members from OWD and two Board members from SWA met as an Ad Hoc Committee or Task Force to discuss potential recycled water opportunities and to look for ways to work together to solve recycled water supply and distribution issues between the agencies. The meeting focused on a joint project with SWA to study the feasibility of recycled water use within SWA’s jurisdiction, through the expansion of the existing infrastructure within the District’s service area. On August 2, 2023, the Board authorized the General Manager to enter a Memorandum of Understanding (MOU) Agreement, which set forth the understanding of the District and SWA for the joint Project. Similarly, on August 9, 2023, the SWA board approved the MOU enabling final execution. The MOU memorialized the agreement of both parties concerning their respective responsibilities and established the financial obligations for each agency to contribute equally (50 percent each). The MOU outlined a phased approach, with the first phase aimed at determining Project feasibility and future phases aimed at potential Project implementation. The study is intended to include an assessment of potential recycled water and other water reuse opportunities, quantities, and customers within both service areas. The study will also prepare feasibility level cost estimates and timelines for infrastructure conversions and construction of any new infrastructure. Lastly, a determination of the regulatory compliance required for project implementation within the SWA service area will be included in the study. In accordance with the Board of Directors Policy Number 21, a Request for Proposal (RFP) was advertised on September 7, 2023 using Periscope S2G, the District’s online bid solicitation website, and the Otay Water District’s website. The advertisement was also placed in the Daily Transcript. Email notifications were also sent to twenty-one (21) engineering firms that have bid on previous projects. The District received Letters of Interest and Statements of Qualifications from six (6) consulting firms. A Pre-Proposal Meeting was held on October 5, 2022, which was attended by six (6) consultants. On November 15, 2023, two (2) proposals were received from the following consulting firms: 1. Carollo 2. Water Systems Consulting (WSC) 3 The following four (4) firms submitted letters of interest, but did not submit a proposal: Michael Baker, HDR, Wood Rodgers, and NV5. Staff contacted each firm to inquire why they did not propose. The common response was firms did not have adequate resources available to conduct the work. The proposals were evaluated and ranked by a five-member review panel consisting of two (2) SWA and three (3) OWD Engineering staff members. On December 20, 2023, both firms were interviewed and ranked by the same five-joint agency member panel. Following the interview scoring, the fee proposals were evaluated, and each received the same score due to a marginal $29 difference in proposal totals, $279,661 (Carollo) and $279,690 (WSC). The fee scores were added and the sum of the scores concluded that Carollo had the best approach to the project and provided the best overall value to the District. A summary of the Proposal Ranking is shown in Exhibit B. Scope and fee negotiations with Carollo were concluded on January 3, 2024, which resulted in a fee increase of $25,809 to their original proposed fee of $279,661. On December 19, 2023, the State of California adopted new regulations for direct potable reuse (DPR). Staff from both agencies agreed DPR should be added to the scope of work. Carollo’s proposed fee to explore DPR as an alternative use of recycled water to the planning study is $25,809. Carollo’s revised proposed fee, with adjustments described above, is $305,470. FISCAL IMPACT: Joe Beachem, Chief Financial Officer The Fiscal Year (FY) 2024 operating budget for this Project for outside services is $50,000 annually starting in FY 2024 through FY 2027. Staff anticipates that the project will be completed in FY 2025. The District’s six-year rate model, as part of the FY 2024 budget, includes sufficient future planned budget associated with this Planning Project. While the timing of the expenditures was not clearly known at the time of the 2024 budget approval, the full funding of the project was incorporated into the District’s rate projections. It is now expected that the full expenditure will be divided between the FY 2024 and FY 2025 years, and while the timing of the expenditures will not match timing of the projected budgets, the extent of the expenditures is included in the projected budgets. The difference in timing is not expected to have a negative impact on the rates. 4 Per the MOU with SWA, the financial obligation for the District’s portion of the Agreement is $152,735, which is half of the not-to- exceed amount of $305,470 for the Planning Study contracted services. GRANTS/LOANS: Engineering staff identified the State Water Resources Control Board (SWRCB) Water Recycling Funding Program Planning Grant (Grant) as a possible funding source for the Project Planning Study. Generally, all costs necessary to determine the feasibility of using recycled water are eligible for the planning Grant. On October 5, 2022, the Board approved Resolution No. 4417 that authorized the submittal of the financial assistance application for a planning grant agreement from the SWRCB for the OWD & SWA Recycled Water Intertie Project. Initially, the Grant application was for $300,000 excluding staff costs. On October 24, 2023, based on a recommendation by the SWRCB Project Manager, the application amount was revised to $500,000 and included staff costs. The Grant, if awarded, could cover up to 100 percent of the eligible planning costs, depending on the SWRCB determination of the Project area’s Disadvantaged Community Status or up to 50 percent if the Disadvantaged Community Status criteria is not met. STRATEGIC GOAL: This Project supports the District’s Mission statement, “To provide exceptional water and wastewater service to its customers, and to manage District resources in a transparent and fiscally responsible manner” and the General Manager’s Vision, "To be a model water agency by providing stellar service, achieving measurable results, and continuously improving operational practices."

NO. 5 APPROVED BY: Beth Gentry, Engineering Manager Michael Long, Chief, Engineering Jose Martinez, General Manager SUBJECT: Approval to Purchase a Pressure Vessel for the Rolling Hills Hydropneumatic Pump Station GENERAL MANAGER’S RECOMMENDATION: That the Otay Water District (District) Board of Directors (Board) authorize the General Manager to issue a Purchase Order to Modern Custom Fabrication, Inc. (Modern) for the purchase of a Pressure Vessel in an amount not-to-exceed $270,000. COMMITTEE ACTION: Please see Attachment A. PURPOSE: To obtain Board authorization for the General Manager to issue a Purchase Order to Modern for the purchase of a Pressure Vessel in an amount not-to-exceed $270,000. ANALYSIS: The District’s Potable and Recycled Water Pressure Vessel Program (Program) was implemented to provide the long-term benefit of preserving the life expectancy of hydropneumatic and surge pressure vessels and reduce the risk of failures. The Program includes routine American Petroleum Institute (API) 510 Pressure Vessel Inspection Code interior and exterior inspections of pressure vessels AGENDA ITEM 5 2 at fourteen (14) pump stations District-wide. The inspection reports provide a list of recommendations for repairs and re-evaluation of the remaining life expectancy of each vessel at the time of the inspection. The Rolling Hills Hydropneumatic Pump Station (RHHPS) pumps into the closed 1100 Pressure Zone serving approximately 225 meters and 30 hydrants. The RHHPS includes the largest pressure vessel in the District at approximately 21,000-gallon volume and a dry weight of 50,000 lbs. The RHHPS hydropneumatic pressure vessel is a key RHHPS component affecting pump cycling frequency, as the 1100 Pressure Zone is operated as a closed zone without a reservoir vented to atmosphere. The 2004 era RHHPS hydropneumatic pressure vessel was most recently inspected on June 6, 2017 and February 27, 2023. Both inspection reports noted interior corrosion due to internal coating failure. The February 2023 inspection report recommended a reduction in the safety relief valve pressure setpoint to compensate for internal corrosion. The February 2023 inspection report also suggested that the life expectancy of the vessel may be three (3) years. Consequently, the report recommended interior re-inspection within three (3) years rather than the typical five (5) year inspection frequency. District staff elected to replace rather than attempt to repair the existing RHHPS pressure vessel since the repair would be complicated by American Society of Mechanical Engineers (AMSE) code recertification requirements. Attempting to repair the vessel carries risk that actual repair costs may possibly be greater compared to the cost to replace it. The life expectancy of a replaced vessel is anticipated to be greater compared to the life expectancy of a repaired/recertified vessel. In preparation for the RHHPS hydropneumatic pressure vessel replacement, District staff developed a plan to deploy the District’s Portable Trailer Mounted Variable Frequency Drive Pump Station (VFD Trailer) at the RHHPS to avoid disruption of water service. VFD Trailer deployment will facilitate replacing the vessel in the same location as the existing vessel by reusing the existing steel piping, conduits, air piping, and foundation to save costs. The District’s as-needed engineering design consultant (Wood Rodgers) structural engineer checked the adequacy of the existing vessel foundation and developed a plan to improve vessel structural baseplate design and add supplemental anchor bolts to the existing foundation stem walls. 3 Deployment of the VFD Trailer and replacement of the vessel will be completed by OWD Utility Maintenance and Pump/Electric/SCADA in-house forces. District staff prepared a specification and redlined existing pressure vessel shop drawings in-house and reached out to eight (8) vessel manufacturers to informally solicit quotes. Four (4) firms submitted informal quotes, including shipping to the project site in Chula Vista, and the results are shown in Table 1 below. TABLE 1 VESSEL MANUFACTURER RAW QUOTE AMOUNT SALES TAX @8.75% SHIPPING COMPARABLE AMOUNT 1 Modern $221,515 $19,383 $4,900 $245,798 2 Dixie Southern $212,071 $18,556 $25,000 $255,627 3 Bulldog $326,558 $28,574 Included in quote $355,132 4 Boardman $436,196 $38,167 $474,363 The Engineer’s Estimate is $250,000. Staff anticipates some modifications will be needed after the review of shop drawings to include District directed changes to meet District operation and maintenance requirements. Subsequently, a ten percent (10%) contingency of $24,202 is included in the award amount to allow staff to modify the purchase order to make District directed changes, if any. Modern successfully manufactured a replacement pressure vessel for the District’s Rancho Jamul Hydropnuematic Pump Station in 2020, which was installed by District in-house forces. Modern also manufactured the existing RHHPS pressure vessel in 2004. Deployment of the VFD Trailer at the RHHPS will provide the added benefit of implementing a deployment plan to facilitate future VFD Trailer deployments at the RHHPS for emergency or future projects. FISCAL IMPACT: Joe Beachem, Chief Financial Officer The total budget for CIP P2663, as approved in the FY 2024 budget, is $3,200,000. Total expenditures, plus outstanding commitments and forecast including this contract, are $1,054,621. See Attachment B for budget detail. 4 Based on a review of the financial budgets, the Project Manager anticipates that the budget for CIP P2663 is sufficient to support the Project. The Finance Department has determined that, under the current rate model, 100% of the funding is available from the Replacement Fund. GRANTS/LOANS: Engineering staff researched and explored grants and loans and found none available for this Project. STRATEGIC GOAL: This Project supports the District’s Mission statement, “To provide exceptional water and wastewater service to its customers, and to manage District resources in a transparent and fiscally responsible manner” and the General Manager’s Vision, "To be a model water agency by providing stellar service, achieving measurable results, and continuously improving operational practices."

NO. ALL APPROVED BY: Andrew Jackson, Chief Water Operations Jose Martinez, General Manager SUBJECT: ANNUAL AS-NEEDED PAVING SERVICES AGREEMENT FOR FY 2025 NOT-TO- EXCEED $250,000.00, PLUS FOUR (4) ONE-YEAR OPTION RENEWAL TERMS, FOR A TOTAL OF $1,250,000.00. GENERAL MANAGER’S RECOMMENDATION: That the Board authorize the General Manager to enter into an agreement for as-needed paving services with Kirk Paving, Inc. (Kirk Paving), in an amount not-to-exceed $250,000.00 for the initial Fiscal Year 2025 term, along with the option of four (4) one-year renewal terms. The total contract value is outlined in the table below, in the amount of $1,250,000.00. Term Year NTE Amount Initial Term FY 2025 $250,000.00 Option to Renew Term 1 FY 2026 $250,000.00 Option to Renew Term 2 FY 2027 $250,000.00 Option to Renew Term 3 FY 2028 $250,000.00 Option to Renew Term 4 FY 2029 $250,000.00 Aggregate Total $1,250,000.00 COMMITTEE ACTION: See “Attachment A.” AGENDA ITEM 6 PURPOSE: To efficiently and promptly perform the essential and critical asphaltic concrete paving work that falls under the District's responsibility, ensuring both cost-effectiveness and timeliness. ANALYSIS: In the normal course of operations, the District is responsible for effectively managing the maintenance and repair of its water infrastructure. This typically involves the regular removal and subsequent re-installation of asphalt paving on public roadways. The District has consistently found that outsourcing the asphalt paving work to contractors is a more effective and efficient approach. As a result, the District has engaged in asphalt paving contract services for over 19 years. The FY 2024 Operating Budget designates $200,000.00 for as-needed paving services under Contracted Services. For the FY 2025 budget, the annual allocation for these services will increase to $250,000.00. This adjustment is a result of escalating costs, and throughout the years, the budgeted amount was nearly exhausted in several fiscal years under the existing contract. Consequently, non-critical paving projects must be deferred to the beginning of the following fiscal year. In accordance with the District’s purchasing requirements, bids for as-needed asphaltic paving services were solicited on November 1, 2023, utilizing Periscope, the District's online bid solicitation portal. The solicitation was also publicized on The Daily Transcript and the District's official website. A pre-bid conference meeting, attended by four potential contractors, was held on November 15, 2023. Subsequently, two bids were submitted through Periscope on December 7, 2023, leading to the following outcome: Bidder: Weighted Score Asphalt & Concrete Enterprises, Inc. (Santee, CA) 2386 Kirk Paving, Inc. (Lakeside, CA) 701 The bidder deemed the most responsive and possessing the lowest weighted score is identified as the lowest responsible bidder. In this instance, Kirk Paving was recognized as such. Contract bids were tendered using a unit-cost approach, considering various work types commonly encountered in paving projects. Each work type was assigned a weight factor, reflecting the District's experience regarding how frequently the contractor is expected to be engaged throughout the duration of the agreement. Multiplying these weights by the unit cost yields a unit score based on the corresponding unit of measurement (e.g., square footage) for the work to be undertaken by the contractor. The unit scores are aggregated to calculate the bid's overall score, and the contractor with the lowest overall score is deemed the lowest bidder. Refer to "Attachment B" for additional details. Notably, Kirk Paving has delivered as-needed asphaltic services to the District for the past five years under the current contract, consistently meeting deadlines and maintaining high- quality work. Staff remains confident in their continued ability to deliver the required tasks. Every year, staff will review paving costs, in anticipation of an increase due to heightened construction activities. Discussions with the contractor will determine whether their unit price remains unchanged or if it will require a reasonable adjustment for an additional year under the contract. Subsequently, staff will propose to either renew the contract for one additional year or initiate a new process, seeking additional proposals from alternative contractors. Therefore, staff aims to negotiate an optional second-year contract that maintains competitiveness. FISCAL IMPACT: Joe Beachem, Chief Financial Officer The FY 2025 budget request includes $250,000.00 for as-needed paving services. The project manager has projected that this requested amount is sufficient to cover the projected expenses for paving requirements in FY 2025 and potential subsequent years if a renewal is approved. STRATEGIC GOAL: Water Distribution System Integrity. As well as maintaining a safe and continuous water supply and safety for the public. LEGAL IMPACT: None.
