The revised total contract amount is not to exceed $4,424,101 including $4,021,911 for basic services and $402,191 for additional services. Background The Regional Water Quality Control Plant’s (RWQCP or Plant) existing secondary treatment process (biological treatment) consists of biotrickling filters followed by an activated sludge process in four aeration basins where micro-organisms break down pollutants. The two-stage system has been in operation since 1980 to remove ammonia and other conventional pollutants and is at the end of its useful life. Upgrades and replacement are needed to reliably treat the wastewater while removing aging equipment and addressing new requirements for nitrogen removal. The San Francisco Regional Water Quality Control Board established new nutrient regulatory requirements in 2019, limiting the total nitrogen loading discharged City of Palo Alto Page 2 from wastewater treatment plants into San Francisco Bay in 2024. The RWQCP’s current wastewater treatment system is an aerobic nitrifying process whereby microbes change the ammonia and organic nitrogen in the wastewater into oxidized nitrogen (nitrate), but the current system does not remove nitrogen. Too much nitrogen in the plant’s effluent could lead to harmful algal blooms, which can release toxins to the Bay and result in insufficient dissolved oxygen in the water to support aquatic life. The State’s regulatory update requires some nutrient removal prior to discharge into the Bay. The Secondary Treatment Process Upgrades project design criteria are based on the new 2019 nutrient loading requirements, an anticipated State target of 15 mg/L of total nitrogen, field inspections, preliminary design evaluations, RWQCP staff recommendations, the recommendations of the 2018 Secondary Treatment Evaluation Technical Memorandum, and the 2012 Long Range Facilities Plan (LRFP). Upgrading the secondary treatment stage to a process that removes harmful nitrogen will be accomplished with anoxic and aerated zones in existing aeration basins. The project will improve final water quality, ensure the plant continues to meet effluent discharge permit limits, and allow for ultimate decommissioning of the aging biotrickling filters and other aging equipment. The upgraded secondary treatment process was initially proposed to decommission the biotrickling filters and convert the aeration basins to a Modified Ludzack-Ettinger (MLE) activated sludge process (or similar process). This process is space-efficient and cost-efficient and allows all biological treatment to take place within the four aeration basins so that biotrickling filters can be decommissioned. However, preliminary designs revealed that the MLE system would have required a second major project in less than ten years to install a fifth aeration basin because the MLE’s process treatment capacity in four aeration basins would be exceeded in 2035, with no ability to take one aeration basin out of service for essential maintenance without violating state rules for effluent discharges. As the preliminary design work proceeded, it became apparent that a better treatment technology had recently emerged (i.e., the Membrane Aerated Biofilm Reactor (MABR) process). The MABR process has greater efficiency, eliminating the need for the future fifth aeration basin as well as allowing essential maintenance without violating state regulations. The project design scope includes both a process upgrade to remove nitrogen and replacement of equipment which has exceeded its design life. The upgrade will allow the RWQCP to meet both the 2019 regulatory requirements as well as an anticipated State target of 15 mg/L of total nitrogen. The Request for Proposals (RFP) for C19171565 was prepared with the best information available at the time of solicitation for design services. The design contract with BC was approved by Council in October 2018 (CMR ID#9485). Since award, BC has performed field survey work, equipment condition assessments, process design modeling, preliminary design calculations, equipment sizing, and prepared plans. It was through this process that the MABR process was found to be superior for the long run, although the shorter-term design and construction costs are higher than for the process originally envisioned. WQCP Capital Program Overview City of Palo Alto Page 3 This project is a key component of the overall investment in the critical infrastructure to provide wastewater treatment to the City and its partners. The Plant’s core infrastructure was built in 1972 with tanks, pumps, large pipes, industrial buildings, acquisition of additional land, and complex mechanical and electrical systems. The 1972 Plant had major capital additions in 1980 and 1988. From 1999 to the present, staff has managed an ongoing $2 to $3 million annual capital improvement program (CIP) reinvestment in aging infrastructure funded on a recurring basis through the partner agreements; the recurring capital budget is increased by an annual inflation index first approved by partner agencies in 1998. Key projects are listed below with major debt financed/grant funded projects in 1972, 1980, 1984, 1988, 1999, 2009, 2010, and 2019. Debt service for larger projects financed through loans or bonds is provided through amendments to the partner agreements. Typical useful life of Plant infrastructure is 30 years for mechanical and electrical gear with most of the Plant at or beyond its useful life. The capital program is a critical commitment to reinvestment in aging infrastructure.

The LRFP was accepted by the City Council on July 2, 2012 (CMR #2914). Implementation of the LRFP is managed by a CIP team of staff engineers, support staff, and a program manager (Woodard & Curran) (see CMR #11612). Near-term project work commenced and is listed below with latest project costs and status.

The 10-year financial forecast is shown below. The 1999 revenue bonds will retire in FY2024. Significant new annual debt service (for the above listed projects) will commence at various times over the next ten years as new capital improvements are realized. City of Palo Alto Page 5 Discussion Additional design services are required to convert to the MABR process, meet the City’s latest design standards, and integrate the new design into the existing process through complicated construction and operation phasing at an operating plant. The amendment includes an increased contract amount of $1,500,745 and the additional time to perform the work. These additions are summarized in Items A – F below:  Item A: Additional Structural Engineering. City policy requires new critical infrastructure to be elevated above sea level rise projections per Palo Alto's Sea Level Rise (SLR) Adaptation Policy (CMR ID#9576) approved by Council March 18, 2019. New equipment, including a Return Activated Sludge (RAS) Pump Station, an Electrical Facility, and a Standby Emergency Diesel Power Generator will be elevated on new concrete pads, complete with access platforms, stairs, and guardrail. The City’s SLR Policy was adopted after issuance of the original RFP. The additional engineering fee provides services to address this need.  Item B: Engineering Design for a New Electrical Facility and Standby Generator. Though it was hoped existing spaces for power distribution equipment could be City of Palo Alto Page 6 repurposed for low cost, predesign studies indicated the impracticality of installing new equipment in both the existing Aeration Basin Blower Room and the biotrickling filter process electrical room. These rooms fail several building code requirements for new construction. A new Electrical Facility is needed to house power distribution equipment. This design will include a new electrical load center to provide unit process power from the Plant’s 12,470-volt power distribution system. The increased electrical load from the improved treatment process requires a new, larger, 2-MW Standby Generator to replace the existing 22-year old 1-MW standby generator, which is also at the end of its useful life. The original engineering fee did not include services for this electrical design.  Item C: Engineering Design for a New RAS Sludge Pump Station. During preliminary design, consideration was given to the complexity of trying to operate the existing Sludge Pumps, while making critical piping tie-ins, and re-routing process pipe to several new locations. Considerable temporary bypass pump and piping systems are required for Plant Operations during the construction phase. Due to increased flow requirements of the new process, the existing RAS Sludge Pumps are now undersized to meet the flow requirements, and these pumps are past their useful life and should be replaced. Building a new RAS Sludge Pump station allows Operations to continue treatment and makes construction feasible for the contractor, while eliminating the need for the contractor to provide large temporary bypass pump and piping arrangements. A new RAS Sludge Pump Station was not originally included in the design contract.  Item D: Process Redesign Effort to Incorporate MABR. After determining that treatment capacity of the aeration basins will reach their limits in about 2035, BC conducted a Feasibility Assessment to evaluate if MABR would be a viable alternative to increase treatment capacity. Preliminary findings and additional process modeling with MABR equipment determined that biological treatment could be achieved through 2054 without the need to construct the expensive fifth aeration basin, thereby saving considerable design and construction costs. Furthermore, due to the efficient oxygen transfer mechanism of the MABR equipment, this process improvement is anticipated to consume less blower air and result in approximately 13% less electrical energy consumption compared to the energy use associated with the operation of a complex and large fifth aeration basin. Most importantly, MABR equipment is modular, allowing for phasing future capital capacity upgrades (after about 2044) only if needed based on pollutant demands, thereby saving the City significant capital expenses if pollutant loads do not increase as anticipated. Staff engineers as well as independent outside consultants (i.e., Woodard & Curran as CIP program manager) evaluated the scope of work and the cost-effectiveness of the MABR process equipment through a Feasibility Assessment and the revised City of Palo Alto Page 7 Treatment Process Basis of Design Technical Memorandum. The MABR equipment is proprietary, made by a company with a proven track record in developing new technology to improve wastewater treatment. Staff reviewed performance reports for new MABR facilities and visited a pilot unit at the Hayward Water Pollution Control Plant, both of which had good performance results. While MABR contributes to an increased design and construction cost in the near term, staff recommends the reliable treatment performance, reduced energy consumption, and improved life cycle cost for the project with MABR. The original design contract did not include research into the MABR product, additional process modeling, developing the Feasibility Assessment, and structural design for support structures and hoist systems associated with the MABR equipment.  Item E: Engineering Design Upgrade of the Lift Station. During preliminary design, it was found that the reconfiguration of the aeration basins has added additional water headlosses, to the extent that the wastewater cannot flow by gravity from the upstream process into the aeration basins. Previous planning work assumed simple replacement of the three existing lift pumps with three new lift pumps for high wet-weather flows. Upon further review of the Plant’s hydraulics, two additional pumps are needed to convey the flow, larger discharge pipes are required, and a different pump and piping configuration is required. Additional pumps and piping re-design were not originally included in the design contract.  Item F: Miscellaneous Design Effort. New equipment requires new space. The equipment and piping in an existing activated sludge pump room will be demolished. The room will be repurposed for new equipment. The process design is based on some key equipment manufacturer’s components, and BC will provide specifications and pre-selection of these components through negotiated fixed pricing guarantees for the installation contractor to prevent undesirable substitutions. These items were not part of the original design contract. The MLE process option originally proposed was estimated to cost $35 million in 2017 dollars. Process modeling of the MLE treatment process found that capacity would be reached in about 2035, only about ten years after the upgraded facility startup. By about 2035, a fifth aeration basin along Harbor Road would be required (at an estimated cost of $41.5 million in 2020 dollars). While the combined cost of these estimates is $76.5 million, it is important to note that the 2017 estimate for the MLE process did not include a number of costly additions that were determined to be necessary as design progressed to 30% on the MABR process, which include new waste activated sludge pumps, new return activated sludge pumps with a new elevated pump station structure, and a new electrical facility and standby generator on elevated structures. These additions would drive the $76.5 million much higher if the earlier estimate were to be reevaluated. City of Palo Alto Page 8 The 30% design opinion of the most probable construction cost estimate for the MABR process project is $97 million in 2020 dollars. That cost includes upgrading the secondary treatment process with MABR technology, decommissioning the biotrickling filters, replacing many equipment components, and takes into account the additional temporary construction measures that will need to be undertaken by the contractor to perform the work, while maintaining the ability to keep the plant operating. Process intensification, which is adding more equipment into a smaller footprint to accomplish more treatment, prolongs the structure and equipment design life, ultimately reducing life cycle capital improvement cost as well as operating and maintenance expenses. It also eliminates the need for a fifth aerator along Harbor Road, adjacent to the Baylands Preserve. Timeline BC has just completed the 30% design and has been authorized to continue working on completion of the 60% design. The detailed design will continue upon Council’s approval of this amendment and is expected to be completed 10 months after Council approval. BC will also provide engineering services during solicitation, bidding, and construction of the project, accounting for the need to extend the contract into 2025. Resource Impact The revised not-to-exceed contract amount will be $4,424,101 including $4,021,911 for basic services and $402,191 for additional services. This is a multi-year contract over the course of design and through the completion of construction. The funding for this amended contract will be allocated from the Wastewater Treatment Enterprise Fund Capital Improvement Program Project, WQ-19001, contingent upon funding appropriation approved by the Council as part of future annual budget cycles. Staff is planning to apply for a State Revolving Fund loan, a USEPA loan, and possibly pursue a revenue bond as sources of funding for the design contract, and future construction and construction management contracts. As the design progresses, the estimated project cost is expected to be adjusted, especially as construction costs become better defined in the future as the design is more complete. Budget adjustments will be brought forward to Council through the annual budget approval process. Because of the City’s budget deficit for FY 2021, COVID-19 shelter-in-place orders, and other related measures, staff approached BC about a potential reduction in their design fee for this Contract Amendment. In the spirit of cooperation and sharing the burden, BC agreed to reduce their fee by about $86,000 on the base services for the Contract Amendment. This amounts to close to a 6% cost reduction, achieved primarily by removing the hourly labor rate escalation on the added work expected to occur after 2020. BC did not reduce the scope of work or the estimated labor hours to complete the contract work. It should also be noted that the proposed design costs are significantly lower than the common figure of about 10% of estimated construction costs. This Contract for professional services permits the City to suspend, in whole or in part, or City of Palo Alto Page 9 terminate the Contract for convenience (with or without cause) by providing written notice by the City Manager. In the event the City finds itself facing a challenging budget situation, and it is determined that City resources need to be refocused elsewhere, the City can terminate for convenience. Other options include termination due to non-appropriation of funds or amending the contract to reduce the cost, for example, by reducing the scope of work. Palo Alto treats the combined wastewater from Palo Alto, Los Altos, Los Altos Hills, Mountain View, Stanford University, and the East Palo Alto Sanitary District. Palo Alto’s share of this project is 38.16% and the other five agencies’ share is 61.84%, based on the fixed capacity established in partners’ agreements. The Secondary Treatment Upgrades Project and the associated costs were discussed with the partner agencies at a July 23, 2020 and November 12, 2020 Partner’s meeting. Partners understand the project and are not opposed to the project. Agreements with partner agencies have been amended to cover this design contract cost. Policy Implications This recommendation does not represent any change to existing City policies. Stakeholder Engagement This project is part of the Plant’s major capital improvement program funded by Palo Alto and its five additional partner agencies. The five partner agencies are regularly updated about both the need for and the progress on wastewater treatment capital work. Updates are provided each year at an annual meeting and at other periodic meetings established to inform partner agency staff about the major capital improvement program. With respect to Palo Alto itself, the open meetings on the budget process serve as the main vehicle for engaging the community on both new projects such as this and associated rate impacts. Environmental Review The project is exempt from review under the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15301, subsections (b) and (e)(1), Existing Facilities, as it involves the repair and maintenance of an existing publicly owned utility used to provide sewerage treatment services with a minor addition to an existing building and no or negligible expansion of use.

INTRODUCTION, BACKGROUND AND PROJECT DESCRIPTION The City of Palo Alto Department of Public Works (City) intends to upgrade its existing two-stage secondary treatment system at the Regional Water Quality Control Plant (“RWQCP”, or the “Plant”), which consists of fixed film reactors (FFRs) followed by activated sludge aeration basins. The upgrade will be to a biological nutrient removal (BNR) process that ensures the capability of meeting NPDES permit requirements during the entire construction phase, startup, and commissioning. This project will decommission the aging FFRs and will provide operation and maintenance (O&M) enhancements upon the upgrade of the entire secondary treatment process, thereby preparing the City for future, more stringent, regulatory changes. II. SCOPE OF SERVICES – GENERAL CONSULTANT shall provide engineering and design services for the completion of the Secondary Treatment Process Upgrade Project (“Project”). This section describes the nature and scope of those engineering and design services. A. CONSULTANT, serving as the Engineer of Record, shall provide engineering services during all phases of the Project from preliminary design, design, bid period services, engineering services during construction, and support during commissioning and start-up. B. CONSULTANT shall design the system such that it can be constructed without interruption to the current treatment operations, except as allowed under special circumstances for piping tie-ins or electrical outages. Pumped by-pass operations will be required by the City’s construction contractor, to allow the project construction work to take place while the Plant remains in operation. C. CONSULTANT shall provide overall coordination of engineering (including civil, structural, mechanical, electrical, instrumentation and controls, etc.) and other disciplines required for the successful development of a consolidated set of detailed design documents consisting of specifications, drawings and opinion of probable cost that will result in a comprehensive construction bid package. The main features of scope of design and engineering services for the process improvements shall include, but not be limited to, the following: DocuSign Envelope ID: 4E57057C-E03B-4C73-B8A8-593B5AD61452 Vers.: Aug. 5, 2019 Page 6 of 37 • Confirmation or update of flow and load projections through 2054, based on population projections provided by the City. • Design the BNR process to re-configure the aeration basins for a 3-step feed process. • Design the 3-step feed process to incorporate Membrane Aerated Biofilm Reactor (MABR) equipment, such to intensify the process and increase capacity to avoid building more infrastructure through 2054. • Design new Return Activated Sludge (RAS) pumping station with RAS chlorination capability. • Design new electrical load center (Secondary Unit Substation) and electrical building(s) to house new MCCs and VFDs serve secondary treatment process to replace the existing electrical switchgear which is beyond its useful life. • Support City through preselection of certain equipment components (Diffusers, MABR) to be included in the Project. • Redesign / upgrade standby power systems. • Redesign / upgrade Intermediate Lift Station (ILS). • Repurpose existing RAS / WAS Pump Room to demolish the existing RAS Pumps and add new pulsed bubble aeration blowers and air receiver tanks. • Add measures to elevate new infrastructure to adapt to sea level rise to comply with the City’s recently adopted Sea Level Rise Policy. • Development of the plant’s hydraulic grade line for daily flow conditions and peak flow conditions with necessary capital equipment to ensure grade line can be met. • Review and update the hydraulic profile of the entire RWQCP. • Assessment of existing blowers to evaluate remaining life and capacity and design a new blower system to replace the existing. • Design of new WAS pumps to meet the pumping requirements of the process modifications. • Comparative evaluation of different types of baffle walls. • Comparative evaluation of various types of blowers, air diffusers, and mixer options. • Type of carbon addition options and planning for future carbon addition should it be required. • Coring and non-destructive testing techniques of the concrete in the existing aeration basins. • Recommendations for repair and rehabilitation of the concrete and structural elements. • Evaluation of options for phosphorus removal solutions should phosphorus regulations be implemented. • Evaluation of operational improvements needed for peak wet weather flows.

The City currently anticipates that the project will be categorically exempt under CEQA Guidelines Section 15301(b), Existing Services, as it involves the repair of an existing publicly-owned utility used to provide sewerage services. Moreover, the construction work planned for this project is within the RWQCP fence line and is anticipated to have no significant environmental impacts to habitat or the public. Prior to the SRF application process, the City of Palo Alto Planning Department, on behalf of the City of Palo Alto as the lead agency under CEQA, will determine whether the Project’s CEQA clearance is a categorical exemption or whether an Initial Study (IS) will be necessary to evaluate any possible significant impacts. If the City requires preparation of an IS, CITY may authorize CONSULTANT to prepare the IS and related CEQA documents (i.e., MND or DocuSign Envelope ID: 4E57057C-E03B-4C73-B8A8-593B5AD61452 Vers.: Aug. 5, 2019 Page 8 of 37 EIR), subject to negotiations between the parties on modifications to the scope of work and schedule for performance, and an amendment to this Agreement. It is to be noted that CITY requires CONSULTANT to engage a sub-consultant specializing in preparing CEQA + documentation, to perform the CEQA Cat Ex or IS / MND related tasks on City projects. For the construction phase of this project, the City seeks to obtain financing through the State Water Resources Control Board (SWRCB) CA Clean Water State Revolving Fund (CCWSRF) or (SRF) Program. In the case of SRF application, the City will be the lead agency for planning and submitting the SRF application package -- which includes General, Financial Security, Technical and Environmental packages – to the SWRCB Division of Finance Assistance (DFA).

AMENDMENT NO. 1 – ADDED SERVICES Notwithstanding Section I above, for the new Tasks added through Amendment No. 1 (which Tasks are identified below in subsection (a) of this Section, the rates in subsection (b) shall apply as of the Effective Date of Amendment No. 1. These hourly rates shall be held constant through the term of the Agreement, without rate escalation, per the price reduction offered by CONSULTANT in recognition of the City’s FY 2021 budget deficit. (a) Added Services CONSULTANT’s scope of work shall include, but not be limited to, the tasks described below. • Add new return activated sludge (RAS) pumping station with RAS chlorination capability • Add new electrical load center and canopy structure to serve secondary treatment process and upgrade standby power system • Add new membrane aerated biofilm reactor (MABR) treatment process coupled with conversion of the existing activated sludge (AS) system to a step-feed biological nutrient removal process • Support City through preselection of certain equipment to be included in the Project • Upgrade Intermediate Lift Station (ILS) • Repurpose existing equipment room • Add measures to adapt to Sea Level Rise Task 2A – Detailed Design Elements of Contract Amendment No.1 CONSULTANT shall develop Design Documents (including Plans, Specifications, Schedule, and Costs) for the following design elements. All design shall go through the proper quality assurance and quality control reviews prior to issuing to the City for review. 2A.1 RAS Pumping Station Design The new RAS pumping station is required to achieve the process performance objectives and improve constructability of the Project. The new RAS pumping station will be integrated with improvements to the existing RAS pumping station serving Secondary Clarifiers 5&6 and other elements of the Project. In addition, RAS pumps and some RAS piping serving Secondary Clarifiers 5&6 will be replaced in the existing structure to DocuSign Envelope ID: 4E57057C-E03B-4C73-B8A8-593B5AD61452 Vers.: Aug. 5, 2019 Page 31 of 37 increase capacity as required for the upgraded treatment process. The new RAS pumping station will be protected against sea level rise and therefore, it will be designed as a structure with a raised pad, pre-fabricated canopy with screened sides, and/or other means to prevent flooding of vulnerable mechanical, electrical, and control systems. The design will include access stairs and handrail as needed. The new RAS pumping station will include capability to chlorinate RAS to control sludge bulking. A new metering pump and piping will be installed at the existing sodium hypochlorite facility serving the Dual Media Filter (DMF) Facility. The new pump will be fed from existing storage tanks installed inside an existing spill containment basin. 2A.2 Electrical Load Center & Upgrade Standby Power System CONSULTANT will design a new unit substation (aka load center) consisting of primary switch, a close-coupled 12 kV/480 V transformer, primary switch gear, and new Motor Control Centers (MCCs) that will be located outdoors on a raised pad. The new Electrical Load Center will be protected against sea level rise and therefore, it will be designed as a structure with a raised pad, pre-fabricated canopy with screened sides, and/or other means to prevent flooding of vulnerable electrical and control systems. The design will include access stairs and handrail as needed. CONSULTANT to design a new standby generator serving Load Centers 3 and 4 to replace the existing that is near the end of its useful service life and does not have capacity for aeration blower and pump loads to be added under the Project. CONSULTANT design to include an automatic transfer switch. The new standby generator will be in the same approximate location as the existing generator and will be designed with protection against sea rise. The capacity of the generator is expected to be approximately 2.0 MW. The new standby generator system will consist of a single equipment skid with integrated mechanical, electrical, and fuel systems. 2A.3 MABR Process Addition CONSULTANT will design an MABR treatment process as an integrated component of the Project based on the findings of the MABR Feasibility Assessment completed under the original contract. The MABR process will increase the capacity of the secondary treatment process to accommodate projected growth in the service area and to achieve the Project’s nitrogen removal objectives without constructing a fifth aeration tank. The MABR system will be installed in the existing aeration tanks. It is expected that implementation of the MABR process will be phased. The first phase, which will be constructed as part of the Project, will have capacity to process flow and loading projected in 2044. In the second phase, which will be constructed under a separate future project, additional MABR equipment will be added to provide estimated DocuSign Envelope ID: 4E57057C-E03B-4C73-B8A8-593B5AD61452 Vers.: Aug. 5, 2019 Page 32 of 37 capacity through at least 2054. The design will include features to facilitate installation of future MABR equipment and bridge cranes serving the MABR equipment. The design also includes an additional internal mixed liquor recycle (IMLR) pump in each aeration tank in the interim period (2 IMLR pumps total per aeration tank). 2A.4 Equipment Pre-Selection Preselection of MABR equipment, aeration diffusers, and the Intermediate Lift Pumps with Formed Suction Inlets will be completed jointly by the City and CONSULTANT. Preselection will be applied only where a single equipment supplier exists or where the preselected equipment is expected to have lower lifecycle costs compared to the alternatives. The CONSULTANT will investigate these equipment alternatives and provide the City with recommendations. 2A.5 Intermediate Lift Station (ILS) Design CONSULTANT’s review of the Plant’s hydraulics determined that a new lift station is required to convey the required range of flow rates. CONSULTANT will design a new lift pump station within the existing structure to meet all Plant flow requirements. Design is to include pump motor / VFD sizing. 2A.6 Repurpose Equipment Room Design Re-design the Equipment Room and demolish the existing RAS pumps and piping will be demolished to allow the room to be used to house new compressors associated with new large-bubble mixing systems to be installed in anoxic zones in the aeration tanks. This effort is expected to require construction sequencing entailing temporary installation and relocation of the new compressors. CONSULTANT shall include the development of a performance specification for a packaged fire sprinkler system for the new Electrical Building, to be purchased and installed by the City’s Construction Contractor for the Project. 2A.7 Sea Level Rise Adaptation Design To comply with the City’s approved the Sea Level Rise (SLR) Adaptation Policy, adopted on March 18, 2019, CONSULTANT will address interim SLR conditions before the long- term adaptation measures are implemented. New facilities included in the Project (RAS Pump Station, Electrical Load Center and Standby Power Generator) will be designed based on a flood level elevation of 13.5 ft above the North American Vertical Datum of 1988 (NAVD88). This interim design flood level is three feet higher than the previous design flood level prescribed by FEMA. Flood protection design measures include raising new facilities to at least elevation 114.0 ft NAVD88 and installation of flood doors at existing equipment rooms. DocuSign Envelope ID: 4E57057C-E03B-4C73-B8A8-593B5AD61452 Vers.: Aug. 5, 2019 Page 33 of 37 The site is in FEMA Base Flood Zone Elevation (10.5 feet NAVD 1988). CONSULTANT shall establish the floor elevation at 14.0-ft above sea level. CONSULTANT shall incorporate in the design any additional pertinent requirements from the City of Palo Alto Sea Level Rise Policy. Incorporating the City Sea Level Rise Policy will require the finished floor elevation of any new structures to be approximately 14.0 feet NAVD88.
