TO TRANSFER RESPONSIBILITY FOR THE OPERATION, MAINTENANCE, REPAIR, UPGRADE, RENEWAL AND REPLACEMENT OF THE SANITARY SEWER PUMP STATION SERVING SUNSET HARBOUR SOUTH CONDOMINIUM (THE "SHSC"), SUNSET HARBOUR NORTH CONDOMINIUM, THE TOWNHOMES AT SUNSET HARBOUR CONDOMINIUM, AND SUNSET HARBOUR YACHT CLUB (COLLECTIVELY, THE "SUNSET HARBOUR PROPERTIES") TO THE CITY, WITH UPGRADES AND ANNUAL CONTRIBUTION FOR OPERATION AND MAINTENANCE COSTS TO BE COVERED BY THE SHSC; AND FOLLOWING SUCCESSFUL NEGOTIATIONS, AUTHORIZING THE CITY MANAGER TO ACCEPT A PERPETUAL, NON -REVOCABLE EASEMENT FOR ACCESS AND USE OF THE PROPERTY OWNED BY SHSC, LOCATED AT 1800 SUNSET HARBOUR DRIVE, IN CONNECTION WITH THE CITY'S PUMP STATION OBLIGATIONS; AND FURTHER AUTHORIZING THE CITY MANAGER TO EXECUTE ANY REQUIRED DOCUMENTS OR AGREEMENTS IN CONNECTION WITH THIS TRANSACTION, WHEREAS, On April 3, 2024, at the request of Commissioner David Suarez, the City Commission approved a referral to FERC, Item C4L, to discuss the possibility of having the City assume control and management of the sanitary sewer pump station ("Sunset Harbour Pump Station') located on the Sunset Harbour South Condominium property, at 1800 Sunset Harbour Drive, which serves the Sunset Harbour South Condominium ('SHSC'), Sunset Harbour North Condominium, The Townhomes at Sunset Harbour Condominium, and Sunset Harbour Yacht Club (collectively, the "Sunset Harbour Properties'); and WHEREAS, the developer(s) of the Sunset Harbour Properties installed a private sanitary sewer pump station rather than provide the required upgrades to the public infrastructure in order to service these four (4) properties; and WHEREAS, the Sunset Harbour Pump Station, which provides critical sanitary sewerage infrastructure, is presently privately owned, operated, and maintained by the SHSC on behalf of the Sunset Harbour Properties; however, due to recurring issues surrounding the operation and lack of maintenance of the Sunset Harbour Pump Station, the SHSC requested that the City take over the operation, maintenance, repair, upgrade, renewal and replacement responsibilities of the Sunset Harbour Properties ("City Pump Station Responsibilities") in exchange for financial compensation to the City, which compensation is being negotiated by the parties; and WHEREAS, sponsoring Commissioner Suarez, as part of the discussion, requested that City staff provide an assessment, recommendations, concerns, and the financial impact to the City for potentially taking on this initiative; and WHEREAS, the Public Works Department completed its initial assessment and presented its results at the June 28, 2024, FERC meeting; and WHEREAS, at the June 28, 2024, FERC meeting, a motion was made to continue the discussion to the next meeting and to have the Administration conduct a search of documents pertaining to development orders and/or any other relevant documentation related to the Sunset Harbour Pump Station and bring it back for discussion; and WHEREAS, on September 20, 2024, FERC members were presented with a signed and sealed set of as -built plans on record, dated 08121/95, which showed two buildings (The Sunset Harbour North Tower and Sunset Harbour South Tower), located on Purdy Avenue as being connected; two additional buildings (Proposed Townhouse 1 and Proposed Townhouse 2), located on 20th Street, were proposed to be connected at a future date; the additional two Townhouse developments, once built, would have required that additional plans be submitted for review and approval by the City and Miami -Dade County Department of Environmental Resource Management (`DERM°) to ensure that the station had adequate capacity; and WHEREAS, during the September 20, 2024 FERC meeting, the SHSC representatives continued voicing their concerns about feared consequences from not having the City take over the Sunset Harbour Pump Station, including public and environmental issues should the pump station overflow into Biscayne Bay; and WHEREAS, the City's Public Works Department advised that by accepting management responsibilities of the pump station, the City would be taking over the financial responsibility of having to hire a consultant to run an analysis of the pump station, to ensure that the design for the system is sound and that the pumps currently in place are at the required operating point that was intended for the system and that the City could be creating a precedent for future requests to take over other existing private pump stations; and WHEREAS, FERC members agreed that while this would be creating a precedent, this was a singular case where an entire neighborhood of over 2,000 residents from four different properties were impacted, and during discussions, FERC requested that the SHSC provide the City with financial documentation and all associated costs for operating the pump station; and WHEREAS, the discussion concluded with a motion from FERC members to move the item to the City Commission, with a favorable recommendation to: (1) engage a third -party consultant to run an analysis of The Properties' Pump Station to determine any required capital improvements scope and associated cost, and (2) work with the City Attorney to negotiate the transfer of Sunset Harbour Pump Station to the City's control, with a cost sharing by the parties after the City has engaged with the consultant to determine the costs; and WHEREAS, on October 30, 2024, the City Commission approved the FERC recommendation at its September 20, 2024 meeting via Resolution No. 2024-33320; and WHEREAS, on December 2, 2024, the City's consultant Hazen and Sawyer ("Hazen") conducted a hydraulic analysis of the Sunset Harbour Pump Station at the cost of $40,000; and WHEREAS, the consultant's report outlines several proposed improvements necessary to bring The Properties' Pump Station up to the City's Code, as defined by the City's Public Works Manual and also outlined requirements for acceptance as a public utility, in compliance with the Miami -Dade County Department of Regulatory and Economic Resources (°RER°) and DERM's Sewer Checklist; and WHEREAS, these proposed improvements included enhancements to site accessibility, structural integrity, mechanical systems, electrical systems, and instrumentation; and WHEREAS, in material part, the following outstanding issues were brought to the attention of the Administration and need to be verified before the City can accept the Sunset Harbour Pump Station: 1. Alternating Pump Operation: Verify with the Association's Engineer of Record ("EOR") that the existing control panel can facilitate alternating pump operation; any proposed upgrades must be permitted by DERM; 2. Explosion -Proof Certification: Confirm with the pump manufacturer that the proposed pumps are rated Explosion Proof Class 1, Group D, Division 1; 3. Surge and Lightning Protection: Ensure the FOR confirms that the proposed panel and pump upgrades include adequate lightning and surge protection; 4. Proximity to Biscayne Bay and Collins Canal: Determine if the pump station is compliant with all RER requirements; and 5. Contamination Concerns: Assess if the RER requires special provisions for excavation due to nearby contamination sites, such as Maurice Gibb Park, which is designated as a brownfield; the presence of asbestos pipes also needs verification; and WHEREAS, the hydraulic analysis indicates that the station's discharge will not adversely impact the City's existing infrastructure and that it will have adequate capacity, contingent upon the installation of the proposed 25 HP pumps, with the installation requiring permitting by RER; and WHEREAS, the required pump station upgrades proposed include various structural, mechanical, electrical, and instrumentation, as more particularly described in the City Commission Memorandum accompanying this Resolution; and WHEREAS, The SHSC operates an internal gravity collection system that serves its residential buildings and Yacht Club, discharging into the pump station's wet well; however, the City does not maintain any gravity systems located within private property and this component would be excluded from the City Pump Station Responsibilities; and WHEREAS, the SHSC is currently under contract with Lift Stations "R" Us for a monthly preventative maintenance service fee of $125 and $4 administrative fees, for an estimated yearly total cost of $1,548; however, these costs are representative of private systems and not public systems that require further monitoring, inspection, and reporting, estimated at $7,500 per month; and WHEREAS, on September 26, 2025, the Public Works staff presented FERC members with both short-term and long-term cost estimates for taking over the operations and maintenance of The Sunset Harbour Pump Station and the Sunset Harbour Properties' legal counsel highlighted a prior agreement by the SHSC, which stipulated that they would be responsible for updating the pump station and pay an annual contribution to the City of $30,000 for its maintenance, over the first three (3) years; and WHEREAS, the FERC members made a motion to move the item to the City Commission with a favorable recommendation, directing the Administration to negotiate an agreement with the SHSC to shift responsibility for operating, maintaining, upgrading, renewing, and replacing the sewer pump station, with upgrades to be covered by the SHSC, and the annual contribution for operation and maintenance to be determined; and WHEREAS, SHSC is still in the process of upgrading the Sunset Harbour Pump Station up to the code required for a private pump station ("Private Pump Station Work"), which structural requirements are less stringent than would be required of a public pump station; and WHEREAS, in order for the City to perform the proposed City Pump Station Responsibility, SHSC will need to grant the City a non -revocable perpetual easement ("EasemenP) for access and use of an easement area ("Easement Area") on over, and under the portion of SHSC's property, where the Sunset Harbour Pump Station is located and over surrounding areas of SHSC's property in order to access the Easement Area and park service vehicles in close proximity to the Easement Area; and transfer of title to the City of the associated piping so that the City's Public Works Department may operate and maintain the assets; and WHEREAS, in connection with a proposed transfer to the City of responsibility for the operation of the Sunset Harbour Pump Station, SHSC shall be required to: (1) secure any and all releases for any existing environmental violations; (2) complete the work and secure the Certificate of Completion for the Private Pump Station Work; (3) secure any required regulatory approvals for the transfer; (4) reimburse the City for the survey to establish the easement area and any other expenses relating to the transaction; and (5) provide the City with Owner's Title Insurance Policy for the Easement; and WHEREAS, there are numerous private pump stations throughout the City, including one located at the New World Symphony, the Loews and Fontainebleau hotels, as well as other locations; however, said locations only maintain their own property, not additional surrounding properties, as is the case with the Sunset Harbour Properties; and WHEREAS, the estimated cost for bringing the pump station up to standard for a public sanitary sewer pump station, including design, construction, legal costs, permitting, operation, and maintenance, would still need to be estimated more closely by a third -party consultant; and WHEREAS, the City Administration advises against the City assuming responsibility for the Sunset Harbour Pump Station due to the significant short- and long-term financial impacts on the Water and Sewer Enterprise Fund; however, should the City Commission decide to assume responsibility for the Sunset Harbour Pump Station, the Administration recommends that the SHSC be fully accountable for all fees associated with the necessary repairs highlighted in the Hazen report to bring the pump station into regulatory compliance as a public pump station, estimated by the City Administration to cost $400,000, plus a contribution towards the pump station's O&M yearly fee; and WHEREAS, should the City Commission choose to accept the FERC recommendation, funding would need to be appropriated in the FY 2027 budget process, with full consideration of its long-term impact, estimated at $1.5 Million, on the Water and Sewer Enterprise Fund. NOW, THEREFORE, BE IT DULY RESOLVED BY THE MAYOR AND CITY COMMISSION OF THE CITY OF MIAMI BEACH, FLORIDA, that the Mayor and City Commission hereby, accept the recommendation of the Finance and Economic Resiliency Committee ("FERC") at its September 26, 2025 meeting, directing the Administration to negotiate an Agreement with the Sunset Harbour South Condominium Association, Inc. to transfer responsibility for the operation, maintenance, repair, upgrade, renewal and replacement of the sanitary sewer pump station serving Sunset Harbour South Condominium(the "SHSC"), Sunset Harbour North Condominium, The Townhomes at Sunset Harbour Condominium, and Sunset Harbour Yacht Club (collectively, the "Sunset Harbour Properties") to the City, with upgrades and annual contribution for operation and maintenance costs to be covered by the SHSC; and following successful negotiations, authorizing the City Manager to accept a perpetual, non - revocable Easement for access and use of the property owned by SHSC, located at 1800 Sunset Harbour Drive, in connection with the City's pump station obligations; and further authorize the City Manager to execute any required documents or agreements in connection with this transaction.

TO TRANSFER RESPONSIBILITY FOR THE OPERATION, MAINTENANCE, REPAIR, UPGRADE, RENEWAL AND REPLACEMENT OF THE SANITARY SEWER PUMP STATION SERVING SUNSET HARBOUR SOUTH CONDOMINIUM (THE "SHSC"), SUNSET HARBOUR NORTH CONDOMINIUM, THE TOWNHOMES AT SUNSET HARBOUR CONDOMINIUM, AND SUNSET HARBOUR YACHT CLUB (COLLECTIVELY, THE "SUNSET HARBOUR PROPERTIES") TO THE CITY, WITH UPGRADES AND ANNUAL CONTRIBUTION FOR OPERATION AND MAINTENANCE COSTS TO BE COVERED BY THE SHSC; AND FOLLOWING SUCCESSFUL NEGOTIATIONS, AUTHORIZING THE CITY MANAGER TO ACCEPT A PERPETUAL, NON - REVOCABLE EASEMENT FOR ACCESS AND USE OF THE PROPERTY OWNED BY SHSC, LOCATED AT 1800 SUNSET HARBOUR DRIVE, IN CONNECTION WITH THE CITY'S PUMP STATION OBLIGATIONS; AND FURTHER AUTHORIZING THE CITY MANAGER TO EXECUTE ANY REQUIRED DOCUMENTS OR AGREEMENTS IN CONNECTION WITH THIS TRANSACTION. The Administration advises against the City assuming responsibility for the Sunset Harbour Towers, Townhomes, and Yacht Club Pump Station ("The Properties' Pump Station") due to the significant short- and long-term financial impacts on the Water and Sewer Enterprise Fund. Should the Mayor and City Commission ("City Commission") decide to assume responsibility for The Properties' Pump Station, the Administration recommends that the Sunset Harbour South Condominium ("SHSC") be fully accountable for all fees associated with the necessary repairs highlighted in the pump station inspection and assessment report completed by Hazen and Sawyer, bringing the pump station into regulatory compliance, and a contribution towards the pump station's Operations and Maintenance ("O&M") yearly fee. Should the City Commission choose to accept the Finance and Economic Resiliency Committee's (FERC) recommendation, it is imperative that any funding be incorporated into the FY 2027 budget process, with full consideration of its long -tens impact, estimated at $1.5 Million, on the Water and Sewer Enterprise Fund and the City's financial stability. 2585 of 3458 BACKGROUND/HISTORY On April 3, 2024, at the request of Commissioner David Suarez, the City Commission approved a referral to FERC, Item C4L, to discuss the possibility of having the City assume control and management of The Properties' Pump Station. The Properties' Pump Station located in the Sunset Harbour neighborhood, are serviced by one (1) sanitary sewer pump station. The developer(s) of these properties decided to install a private pump station rather than provide the required upgrades to the public infrastructure in this neighborhood in order to service these four (4) properties. The Properties' Pump Station, which provides critical sanitary sewerage infrastructure, is presently privately owned, operated, and maintained by the SHSC, which represents these properties. However, due to recurring issues surrounding the operation and lack of maintenance of the pump station, the SHSC requested that the City take over the management, operation, and maintenance responsibilities of The Properties' Pump Station in exchange for financial compensation to the City (yet to be determined). Sponsoring Commissioner Suarez, as part of the discussion, requested that City staff provide an assessment, recommendations, concems, and the financial impact to the City for potentially taking on this initiative. The Public Works Department completed its initial assessment and presented its results at the June 28, 2024, FERC meeting, listed below: This particular pump station has been undergoing upgrades, which have not yet been completed. It was recommended that the upgrades be completed and approved before completing any transfer of ownership. It was also recommended that a third -party consultant evaluate the existing conditions, the proposed/ongoing improvements, additional requirements for public utility operation, which are more stringent than those for privately operated pump stations, and provide a recommendation for any applicable additional improvements needed and their cost. The transfer will require and is subject to regulatory approval. Since the pump station is on private property, the City requires legal instruments, non -revocable permanent easements, or transfer of title to the land occupied by the station and the associated piping so that Public Works can operate and maintain the assets. There are numerous private pump stations throughout the City, including one located at the New Wodd Symphony, the Loews and Fontainebleau hotels, as well as other locations. Should the City decide to take over the Property's Pump Station, similar requests from other property owners may potentially follow. The estimated cost for bringing the pump station up to standard, including design, construction, legal costs, permitting, operation, and maintenance, would need to be estimated by a third -party consultant. At the June 28, 2024, FERC meeting, a motion was made to continue the discussion to the next meeting and to have the Administration conduct a search of documents pertaining to 2586 of 3458 development orders and/or any other relevant documentation related to The Properties' Pump Station and bring it back for discussion. On September 20, 2024, FERC members were presented with a signed and sealed set of as - built plans on record, dated 08/21/95, which showed two buildings (The Sunset Harbour North Tower and Sunset Harbour South Tower), located on Purdy Avenue as being connected. Two additional buildings (Proposed Townhouse 1 and Proposed Townhouse 2), located on 20th Street, were proposed to be connected at a future date. The additional two Townhouse developments, once built, would have required that additional plans be submitted for review and approval by the City and Miami -Dade County Department of Environmental Resource Management ("DERM") to ensure that the station had adequate capacity. Discussions followed by SHSC representatives and City staff. The SHSC continued voicing their concerns about feared consequences from not having the City take over The Properties' Pump Station they currently manage, including public and environmental issues should the pump station overflow into Biscayne Bay. Public Works stated that by accepting management responsibilities of the pump station, the City would be taking over the financial responsibility of having to hire a consultant to run an analysis of the pump station, to ensure that the design for the system is sound and that the pumps currently in place are at the required operating point that was intended for the system. Additionally, the Citywould be creating a precedent for future requests to take over other existing private pump stations. FERC members agreed that while this would be creating a precedent, this was a singular case where an entire neighborhood of over 2,000 residents is impacted. Also, there was an absence of documents proving a maintenance agreement was in place or formally executed. Discussions continued regarding the City taking over the operational side of the pump station. It was requested that the SHSC provide the City with financial documentation and all associated costs for operating the pump station. Once the City engaged a consultant for design and provided cost estimates (consulting fee estimated at $100,000.00), the Administration would review the SHSC operating costs and negotiate the sharing of the ongoing operating costs. The discussion concluded with a motion from FERC members to move the item to the City Commission, with a favorable recommendation to: (1) engage a third -party consultant to run an analysis of The Properties' Pump Station to determine any required capital improvements scope and associated cost, and (2) work with the City Attorney to negotiate the transfer of The Properties' Pump Station to the City's control, with a cost sharing by the parties after the City has engaged with the consultant to determine the costs. On October 30, 2024, the City Commission approved the FERC recommendation at its September 20, 2024, meeting via Resolution No. 2024-33320. On December 2, 2024, the City's consultant Hazen and Sawyer ("Hazen") conducted a hydraulic analysis of The Properties' Pump Station at the cost of $40,000. At the time of the analysis, the pump station was operating with a single functional pump of unknown manufacture with no redundancy in place in the event of a pump failure. The SHSC indicated plans to purchase two 25HP Grundfos pumps to be connected to a new control panel, which had already been constructed under Building Commercial Permit No. BC 1911677. However, during the inspection, this control panel was not connected to a power source, either from Florida Power & Light ("FPL") 2597 of 3458 or a temporary generator. Hazen's analysis was conducted based on the proposed future installation of the two 25HP Grundfos pumps. The consultant's report outlines several proposed improvements necessary to bring The Properties' Pump Station up to code, as defined by the City's Public Works Manual. The report also outlines requirements for acceptance as a public utility, in compliance with the Miami -Dade County Department of Regulatory and Economic Resources ("RER") and DERM's Sewer Checklist. These proposed improvements include enhancements to site accessibility, structural integrity, mechanical systems, electrical systems, and instrumentation. The outstanding issues listed below will need to be verified before the City can accept managing the pump station. A more extensive explanation can be found in the final report ("Attachment A"): Pending Issues Needing Clarification: There are several known outstanding issues that have been brought to the attention of the Administration, including: 1. Allemating Pump Operation: Verify with the SHSC's Engineer of Record ("EOR") that the existing control panel can facilitate alternating pump operation. Any proposed upgrades must be permitted by DERM. 2. Explosion -Proof Certification: Confirm with the pump manufacturer that the proposed pumps are rated Explosion Proof Class 1, Group D, Division 1. 3. Surge and Lightning Protection: Ensure the FOR confimrs that the proposed panel and pump upgrades include adequate lightning and surge protection. 4. Proximity to Biscayne Bay and Collins Canal: Determine I the pump station is compliant with all RER requirements. 5. Contamination Concerns: Assess if the RER requires special provisions for excavation due to nearby contamination sites, such as Maurice Gibb Park, which is designated as a brownfield. The presence of asbestos pipes also needs verification. Hydraulic Analysis, Pump Station Upgrades, Financial Considerations, and The Properties' Responsibilities: The hydraulic analysis indicates that the station's discharge will not adversely impact the City's existing infrastructure and that it will have adequate capacity, contingent upon the installation of the proposed 25 HP pumps. The installation will require permitting by RER. The required pump station upgrades proposed include the following structural, mechanical, electrical, and instrumentation listed below: • Resurface and recoating of the wet well to address significant concrete pitting caused by hydrogen sulfide (H,S) exposure and prevention of further deterioration. • Sandblast and coating of the interior of the valve vault, the valve vault piping and appurtenances, and discharge piping. • Install an access ladder for the valve vault, if feasible, given space constraints within the existing vault. • Provide pipe support for the riser pipes within the wet well. • Provide support for the guide rails within the wet well. • Install watertight hatches on the wet well and valve vault. • Install new 25-hp pumps along with associated wet well discharge piping to restore normal operation and remove bypass (currently under procurement by the Sunset Harbour South Condominium). • Address grease buildup in the wet well. 2588 of 3458 • Install three (3) additional ETMs to track the total operational hours of the control panel in accordance with City standards and DERM requirements. • Install a plug valve outside the valve vault to facilitate isolation and maintenance. • Install flexible coupling, mega flange, or other dismantling joint for valve vault piping. • Implement odor control measures on wet well vent. • Install a level transducer and one (1) additional float switch to improve pump control in zrnordance with City standards. • Install pressure transmitters in the valve vault to measure system pressure and improve operational monitoring. • Install a pressure gauge in the valve vault. • Incorporate telemetry for remote monitoring ofthe Private PS and/or confirm that proposed telemetry is compatible with the City's existing SCADA system. • Energize the new control panel promptly, as prolonged unpowered storage outside is not recommended. The SHSC operates an internal gravity collection system that serves its residential buildings and Yacht Club, discharging into the pump station's wet well. It is important to note that any future agreements with the City must explicitly exclude this gravity system as these assets are located within private property and are difficult to access with City maintenance vehicles. Proper maintenance of the gravity system is essential to prevent adverse effects on the pump station. A maintenance schedule and log must be submitted to the City. The SHSC would remain responsible for the maintenance of the gravity sewer system as well as for conducting all required testing, inspections, and reporting that may be required by DERM and FDEP. Furthermore, the SHSC must ensure that flows to the station do not increase due to factors such as inflow or infiltration, as higher flows could result in extended pump operating hours. The RER oversees city pump stations, and prolonged pump run times could lead to a moratorium declaration. The SHSC is currently under contract with Lift Stations "R" Us for a monthly preventative maintenance service fee of $125 and $4 administrative fees, for an estimated yearly total cost of $1,548. These costs are representative of private systems and not public systems that require further monitoring, inspection, and reporting, estimated at $7,500 per month. A breakdown of City costs was shared with SHSC for their review. Additionally, the City is working to reduce costs associated with critical water and sewer projects, and incorporating this pump station would add to O&M budgeted expenses. On September 26, 2025, the Public Works staff presented FERC members with both short-term and long-temr cost estimates for taking over the operations and maintenance of The Properties' Pump Station. The Properties' Pump Station' legal counsel highlighted a prior agreement by the SHSC, which stipulated that they would be responsible for updating the pump station, estimated at $400,000, and an annual contribution to the City of $30,000 for its maintenance, over the first three (3) years. The Properties' Pump Station' legal counsel concluded by stating that the SHSC did not wish to manage a public utility. After considering both perspectives, FERC members reached a compromise and made a motion to move the item to the City Commission with a favorable recommendation, directing the Administration to negotiate an agreement with the SHSC to shift responsibility for operating, maintaining, upgrading, renewing, and replacing the 2589 of 3458 sewer pump station, with upgrades to be covered by the SHSC, and the annual contribution for operation and maintenance to be determined. FISCAL IMPACT STATEMENT The current planning level estimate for essential upgrades to the station, upon transfer, is $359,000. This includes basic nece<sities to ensure proper operation. The estimated annual O&M cost to maintain the Pump Station is approximately $60,000, with future years increasing due to inflation. These O&M costs are not inclusive of Rehabilitation and Replacement ("R&R") costs that would take place every 10 to 15 years. The permits, survey, title and attorney's fees are estimated at $18,000. The total cost of accepting the pump station is approximately $437,000 for the first year alone. Long-term Rehabilitation and/or replacement costs shall also be considered. Depending on the extent of the rehabilitation or replacement that is necessary, the cost could be as high as $1.5M (bringing the station to standards, R&R and complete rehabilitation costs every 15 years, estimated in 2025 dollars), inclusive of mobilization, mechanical, structural, electrical rehabilitation and engineering costs. Does this Ordinance require a Business Impact Estimate? (FOR ORDINANCES ONLY) N applicable, the Business Impact Estimate (BIE) was published on: See BIE at: https:llwww.miamibeachfl.gov/city-hallicity- lerkimeetinu-notices) CONCLUSION The Administration advises against the City assuming responsibility for The Properties' Pump Station due to the significant short- and long-term financial impacts on the Water and Sewer Enterprise Fund. Should the City Commission decide to assume responsibility for The Properties' Pump Station, the Administration recommends that the SHSC be fully accountable for all fees associated with the necessary repairs highlighted in the pump station inspection and assessment report completed by Hazen, bringing the pump station into regulatory compliance, and a contribution towards the pump station's O&M yearly fee. Additionally, should City Commission members recommend funding for the managing of the pump station, the Administration recommends that it be considered as part of the FY 2027 budget process and to be added as an asset and future expense in the CIP plan used to calculate rate adjustments in the Water/Sewer Rate Study. City Commission members should also carefully consider several critical factors that will significantly impact the Water and Sewer Enterprise Fund Budget, beginning in FY 2027: • The City's increasing unfunded capital improvement program. • Long-term General Fund financial projections indicating a potential shortfall in the upcoming fiscal year. • The passage of Amendment 5 in November 2024, which increases the homestead exemption and further constrains the growth of taxable property values. These considerations are essential to ensuring that decisions regarding assuming control of The Properties' Pump Station align with the City's broader long-term financial stability and strategic priorities. 2590 of 3458 Applicable Area South Beach Is this a "Residents Right to Know" item.

Giacchino Project Engineer Public Works Department City of Miami Beach cc: Giancarlo Pena, PE, Interim City Engineer Aaron Osborne, Project Engineer, Engineering Division Mariela Paez Castillo PE, Planning and Design Manager Re: Purdy Avenue Private Pump Station Engineering Assessment and Hydraulic Analysis 1. Introduction and Background The City of Miami Beach (City) is located in the east portion of Miami -Dade County and encompasses an area of approximately 7.69 square miles with an estimated population of over 80,000 residents. The City owns, operates, and maintains the wastewater collection and transmission system which includes 23 pump station (PS) service areas (basins), approximately 117 miles of gravity sewer maim, approximately 26 miles of active force mains, and over 3,100 manholes. Wastewater is collected throughout the service areas and is pumped to Miami -Dade Water and Sewer Department's (MDWASD's) Central District Wastewater Treatment Plant (CDW WTP) for treatment and disposal. The City has engaged Hazen and Sawyer (Hazen) to assess a Private PS whose owners have expressed interest in tmnsitioning ownership, operations, and maintenance to the City. The Private PS, which is currently owned, operated, and maintained by Sunset Harbour Condominiums, is located at I800 Sunset Harbour Drive along Purdy Avenue. The station is a key component of the condominium's wastewater infrastructure, conveying sewage from the north and south buildings. Once at the Private PS, the Bows are pumped through a City -owned 6-inch force main before discharging into the City's manifold force main system via a 16-inch sewer force main new the intersection of Dade Boulevard and Purdy Avenue, as shown in Figure 1-1 (next page). This evaluation focuses on assessing the Private PS's structural, mechanical, electrical, and operational conditions, along with its regulatory compliance and potential upgrade needs. Hazen was provided with the following information to utilize in the evaluation: • Sunset Harbour Place Sewer Plans, signed 11/01/1995 • Sunset Harbour Place 6-inch Force Main As -Built Plans, dated 07/05/1996 • Private PS Sewer Hydraulic Analysis written by the City, dated 06/022022 A copy of the above documents are included herewith in Appendix A. Pace I 2592 of 3458 1 i t t f Hazen Memorandum 2. Condition Assessment Hazen conducted a condition assessment of the Purdy Avenue Private PS on December 2, 2024. Summaries of the structural, mechanical, instrumental, and electrical observations are provided below, with the detailed inspection report and photographs included in Appendix B. 2.1 Structural Observations The structural condition of the PS was generally fair. The following items are in need of attention: • Wet Well: The wet well structure exhibited noticeable concrete pitting due to exposure to hydrogen sulfide (HrS) gas. There was no noticeable presence of a liner or protective coating for the concrete. • Valve Vault: The valve vault was in generally good condition. However, debris has accumulated at the bottom due to the vault being designed with an open bottom. • No supports were present for the guide mils within the wet well. 2.2 Mechanical Observations At the time of the inspection, the Private PS was on bypass, awaiting the installation of two (2) new Grundfns 25-hp pumps (currently under procurement by the Sunset Harbour South Condominium). The bypass system was comprised of a single pump, of unknown make and model, supported between the wet well and valve vault, with suction hard piped from the wet well and discharging to the emergency pump out within the value vault. Information on the new pumps to be provided for the Private PS is included in the estimate by Just I Plumbing provided by the Manager of the Sunset Harbor Condominium, included in Appendix C. All permanent discharge piping within the wet well was removed. It was also noted that there was minor grease buildup within the wet well. The station discharge piping between the wet well and valve vault is exposed and above grade. The discharge piping is 4-inch ductile iron. Within the valve vault, the station is equipped with check and quarter -turn plug valves, and a 4-inch pump out connection. This piping is corroded and appears either uncoated or its coating has deteriorated. If not addressed, this condition could lead to further degradation over time. 2.3 Instrumental Observations At the time of inspection, the instrumentation components of the Private PS were in the process of being upgraded under the City's Building Permit Number BC1911677 (permit card included as Appendix D). The proposed instrumentation and electrical plans are included in Appendix E. Hazen evaluated both the existing and new infrastructure as available during the inspection. Two (2) control panels were observed: 2594 of 3458 I "', Hazen Mardi `I. ")'5 Older Control Panel: This panel showed significant corrosion and wear. This panel was currently in use providing power to the bypass pump in operation. Two elapsed time meters were present to record pump run times. No other instrumentation was present in the panel. • Newer Control Panel: This panel was in good condition, wit had not yet been put into operation. Haan understands that the new control panel and its associated equipment will become operational only once the new pumps are installed. The following components were observed in the newer control panel: o Four (4) Boat switches designed to control pump activation based on water levels in the wet well. o Two (2) elapsed time meters (ETMs) to track the operational hours of each pump. o Local alarms to notify personnel in the immediate area. 2.4 Electrical Observations At the time of inspection, the electrical components of the Private PS were in the process of being upgraded under the City's Building Permit Number BC1911677 (permit card included as Appendix D). The proposed instrumentation and electrical plans are included in Appendix E. Hazen evaluated both the existing and new infrastructure as available during the inspection. In general, it was noted that no site lighting was available. Two (2) control panels were observed: • Older Control Panel: During the inspection, the panel was operational to support the Private PS in bypass mode. • Newer Control Panel: The electrical system was found to be rated at 200A, 240V, 3-phase. This system is intended to supply power to two (2) future 25-hp pumps via full voltage non -reversing (FVNR) starters, along with other miscellaneous loads such as receptacles, lighting, and control equipment. The new panel was also equipped with a generator receptacle plug to provide an alternative means for providing power to the station during electrical service disruption. Other electrical components observed include a 200A enclosed main circuit breaker, conduits running from the new control panel to the wet well, and conduit seals for conduits running into the new control panel. 2595 of 3458 Hazen Public Work Standards Review A preliminary renew of Section 16 -Sanitary Sewer Force Mains and Pump Stations from the City's Public Works Manual (PWM) (Hazen, 2021) was performed in conjunction with the condition assessment to identify where the Private PS deviates from specified configurations and/or design standards required by the City. Section 16 from the PWM is included as Appendix F. Please note that not all deviations from the City's standards are identified throughout this assessment, but this review was performed to identify deviations that could have major impacts on maintenance, operation, and regulatory compliance. 3.1.1 General The following general site related items were noted at the pump station: • Access to Private PS appears to be mainly though the private property side. • Limited/no dedicated parking is available for pump station access and maintenance. • There was no site security via fencing, locks, etc. to limit access and secure the Private PS site. 3.1.2 Structural The following details, which appear in the City's PWM, particularly standard details 16-20 and 16-21 for pump stations, were not observed at the station: • Ladder entry into the valve vault. • Enclosed valve vault (with bottom slab) with a drain line to the wet well. • Pipe supports for the riser pipes within the wet well (no riser pipes were present at the time of inspection). • No supports present for the guide tails within the wet well. (Please note, typically the guide rail support would be provided by the pump manufacturer. Based on the proposal from Just I Plumbing provided by the Sunset Harbor Condominiums South Manager, included in Appendix C, new guide rails are being provided with new pumps, excluding supports). 3.1.3 Mechanical The following details, which appear in the City's PWM, particularly standard details 16-20 and 16-21 for pump stations, were not observed at the station: • Pressure transmitters. • A plug valve outside of the valve vault for assistance in station isolation and maintenance (not a regulatory requirement however it is noted since it is shown on the City Standard Detail 16-20). • Flexible coupling, megananges or other type of dismantling joints for valve vault piping. The current pipes are hard -pipped, which would make it difficult to access for maintenance. P:m 2596 of 3458 Hazen %I ,' • Odor control for the wet well vent. 3.1A Instrumentation The following details, which appear in the City's PWM, were not observed at the station: Telemetry. The plans for the new control panel (included in Appendix E) included a RTU, however, a wireless telemetry system that has the following components is required by the PWM: o Pump I running o Pump I in AUTO o Pump I alarm a Pump 2 running o Pump 2 in AUTO o Pump 2 alarm o Wet well high level alarm o Wet well low level alarm o Wet well level (if a level transducer is provided) o LCP intrusion alarm o Pump station discharge header pressure (if pressure transducer is provided) o Power fault o Power loss o Generator operating (if a generator is provided) o Generator cool down (if a generator is provided) o General fuel tank level (if a generator is provided) • Five (5) ETMs (only two (2) were observed) to track the operational hours of: o Pump I running o Pump 2 running o Pump I and Pump 2 running simultaneously o Pump 1 running 1-5AM o Pump 2 running 1-5AM 2597 of 3458 P:wc e Hazen .,cs .

It is possible that these items may be present, but they need to be confirmed by the Engineer of Record (EOR) for the new control panel. Pa^r 2598 of 3458 Hazen 4. Regulatory Review Nhrd, , I,'W A preliminary regulatory review of the Private PS was conducted using the Miami -Dade County Department of Regulatory and Economic Resources (RER) Division of Environmental Resources Management (DERM) Sewer Checklist. This review ensures adherence to local sewer design and operational standards by evaluating key regulatory requirements as required by Miami -Dade County Code. The DERM checklist review aims to identify any non -compliant areas within the Private PS that may be noted by DERM during future sewer extension permitting efforts for the station. A completed checklist for the Private PS is included as Appendix G, noting which requirements are not applicable to the station, which criteria are currently met, and which areas are non -compliant. The following items were noted: 4.1 Engineering Technical Review • Electrical Equipment and Wet Well Hatch Elevations — The 100-year Flood elevation per FEMA is 8-feet NGVD as shown in Appendix H. The critical flood criteria elevation for the station in accordance with DERM requirements is: 8-feet NGVD + 1-foot freeboard + 9-inches Sea Level Rise = 9.75 feet NGVD o The new control panel is elevated such that its bottom is above 9.75-11eet NGVD, as indicated on the electrical plans (Appendix E). As such, the proposed electrical equipment is anticipated to meet the minimum critical Flood criteria elevation. However, it is unknown at the time of this analysis if the panel upgrades have been permitted with DERM. o The Private PS as-builts show the wet well and valve vault hatches to be approximately 6- feet NGVD (Appendix A). These elevations are below the required 9.75 feet NGVD. Therefore, watertight hatches need to be installed on the wet well and valve vault, and the new hatches would need to be permitted with DERM. • Contaminated Site —Per the EDEP Contamination Location Map tool (see printout included as Appendix 1), the adjacent Maurice Gibb Park is considered a brownfield site and has petroleum contamination. As such, DERM may have special requirements regardingany excavation proposed at the Private PS site. • Asbestos — The presence of asbestos concrete pipe or other asbestos materials would need to be determined based on future Sunshine 811 utility record investigations or other methodology as appropriate. If asbestos materials are fmmd to be present DERM may have .special requirements regarding any excavation proposed at the Private PS site. Please note, this requirement is typical for all work performed by the City. • Designated Critical Habitat — Due to the Private PS's locution adjacent to Biscayne Bay. DERM may have additional requirements for any future work proposed at the Private PS site. Please note, these additional requirements are typical for many of the City's PSs due to their proximity to Biscayne Bay. • Canal Impacts —Due to the Private PS'.s location adjacent to Biscayne Bay and Collins Canal, DERM may have additional requirements for any fimtre work proposed at the Private PS site. 2599 of 3458 Hazen VI.ircC' I. '0'9 Please note, these additional requirements are typical for many of the City's PSs due to their proximity to the Biscayne Bay and/or canals. , 4.2 Pump Station • Pumps Capability to Pass 3-inch Sphere —The proposed pump cut sheet (Appendix J) notes that "free passage through the pump varies from 35-125 must depending on size and hydraulic variant" of the pump model. The capability of the pumps to pass, at a minimum, a 3-inch spherical solid should be confirmed with the pump manufacturer. Ifthe pumps cannot meet this requirement. then it is recommended to select a different pnmp model for installation. • Odor & Noise Control — Based on the site visit and a review of the as -built drawings, no odor controVreduction appears present on the wet well vent. DERM may require a charcoal fiber (or other odor control system) he installed on the wet well vent. The pumps are located approximately 15-feet below grade based on the as -built drawings (Appendix A). Typically, this is considered to be adequate noise control. As such, no additional noise control is anticipated to be required. • PS Rated Capacity — The proposed Gnmdfos pumps will need to be permitted with DERM and a hydraulic analysis performed to determine pump.station capacity. • Pump Models are Explosion Proof (Class 1, Group D, Division 1) — This rating should be confirmed with the proposed pump manufacturer. if the pumps cannot meet this requirement. then it is recommended to select a different pump model for installation. • Lightning and Surge Protection — It is recommended to confirm with the FOR of the new control panel that the new panel and pump upgrades have adequate lightning and surge protection. The proposed upgrades will need to he permitted with DERM. • Alternating Pumps - It is recommended to confirm with the FOR of the new control panel that the new panel upgrades will allow for the pumps to he operated in an alternating fashion. The proposed upgrades will need to he permitted with DERM. 4.3 Utility • ET Meters —As noted in Section 3.1.4 of this assessment, a total of five (5) ETMs are required. It appears the new panel is only equipped with two (2). 11 is recommended to install three (3) additional ETMs, which can he done with a separate panel. • Electrical Equipment and Wet Well Hatch Elevations — This requirement was addressed under the "Engineer Technical Review" section of the DERM checklist. Please see Section 4.1 above. 2600 of 3458 Hazen 4.4 Force Main March _' I ?o] 5 • None — The force main criteria shown on the checklist appear to be met based on review of the as -built drawings (Appendix A) and hydraulic modeling detailed in Section 6 of this assessment. 2601 of 3458 Hazen 5. Recommendations )Loth'I.'W] Based on the condition assessment, PWM, and regulatory review, the following actions are recommended: a General o Verify easement in place for the Private PS and conveyance to City. o Improve vehicular access to the wet well and valve vault by considering dedicated City parking spots, removing existing bushes, or making other modifications, as current access may require entry through private property in the condominium driveway. o Enhance site security by installing locks and/or gates to restrict unauthorized access and protect station equipment. • Station Upgrades o Resurface and recoat the wet well to address significant concrete pitting caused by hydrogen sulfide (H.S) exposure and prevent further deterioration. o Sandblast and coat the following: Interior of the valve vault • Valve vault piping • Station discharge piping o Install a ladder entry into the valve vault, if feasible given space constraints within existing vault. o Provide pipe support for the riser pipes within the wet well. o Provide support for the guide rails within the wet well. o Install watertight hatches on the wet well and valve vault. o Install new 25-hp pumps along with associated wet well discharge piping to restore normal operation and remove bypass (currently under procurement by the Sunset Harbour South Condominium). o Address grease buildup in the wet well. o Install three (3) additional ETMs to track the total operational hours of the control panel in accordance with City standards and DERM requirements. o Install a plug valve outside the valve vault to facilitate isolation and maintenance. o Install flexible coupling, megaflange or other dismantlingjoint for valve vault piping. o Implement odor control measures on wet well vent. 2602 of 3458 Hazen March ]I, Wi o Install a level transducer and one (I) additional float switch to improve pump control in accordance with City standards. o Install pressure transmitters in the valve vault to measure system pressure and improve operational monitoring. o Install a pressure gauge in the valve vault. o Incorporate telemetry for remote monitoring of the Private PS and/orconfirn that proposed telemetry is compatible with the City's existing SCADA system. o Energize the new control panel promptly, as prolonged unpowered storage outside is not recommended. . Regulatory Compliance Verification: o The City should confirm if the following existing/proposed upgrades are compliant with DERM requirements, if not, upgrades will need to be made to ensure regulatory compliance: • The capability of the pumps to pass, at a minimum, a 3-inch spherical solid should be confirmed with the pump manufacturer. Confirm the pump is rated Explosion Proof Class I, Group D, Division I with the pump manufacturer. _ • Confirm with the FOR that the proposed panel and pump upgrades have adequate lightning and surge protection • Confirm with the FOR that the proposed panel upgrades will allow for the pumps to be operated in an alternating fashion. . Permitting o Both the Sunset Harbour Condominiums and the City should coordinate with DERM to determine if any of the existing and proposed components of the pump station are unpernitted, including but not limited to the following: • Proposed electrical upgrades. • The installation of watertight hatches. • Proposed pump upgrades. • Station bypass. o The City could request all permits and records DERM has on file for the station, allowing the City and Hazen to review and identify any unpermitted components. pace I, 2603 of 3458 Hazen Environmental Impact o The City shoved note that DERM may hnc special requirements for work at the Private PS due to its proximity to the following protected sites: • Biscayne Bay. • Collins Canal. 2604 of 3468 Hazen 6. Hydraulic Analysis March _[, 20_'s A hydraulic analysis was performed to evaluate the operational capacity and performance of the Private PS, in addition to evaluating its impact on the City's sewer system. This analysis is based on the following: • InfoWorks hydraulic sewer model developed and calibrated by Hazen under a previous task order, as described in City of Miami Beach Sewer Transmission System Hydraulic Model Report (Hazen, 2019) • Dry and wet weather Bows for the entire Miami Beach Model were updated based on recent hydrologic calibrations summarized in the April 25, 2024, DERM submittal Sewer Collection and Transmission System Hydraulic Model Calibration (Hazen, 2024). • The sewer system hydraulic model considers Flows from the following developments: • 500 and 600 Alton Road • Symphony Park Hotel (1685 Washington Avenue) • Bayshore Park • Abbott Avenue • 72n° and Park • Pump Station I Rehab and Discharge Farce Mains • Collins Park • 4000 Alton Road • 6747 Collins Avenue • Sunset Island • Venetian • 7140 Abbott Avenue • Convention Center Hotel • Alton Road Pump Station 25 • Bal Harbour Shops • 3900 Alton • Indian Creek Village • Shore Club • Town Center Gateway 6.1 Private Pump Station Future Pump Curve and Current Flow Analysis As stated in Seedon 2 of this assessment, the Private PS will be operating with two (2) new pumps in the future. The associated future pump curve is provided in Appendix J. The future pump's characteristics are listed below in Table 6.1.

Based on the Miami -Dade County Code (MDCC) land use definitions, the total sewer Bow per apartment unit is 135 gpd per unit. As such, the average daily Bow (ADF) is 21.5 gpm (30,915 gpd) for the north building and 19.9 gpm (28,620 gpd) for the south building, as shown in Table 6.2 below.

Based on this, the peaking factor for the condominium flows was determined to be 2.298 with a peak hourly flow (PHF) of 95.1 gpm (136,811 gpd), as presented in Table 6.3. Table 6.3: Purdy Avenue Private Pump Station PHF 6.2 Existing Hydraulic Conditions with Future Pumps 6.2.1 Summary of Existing Conditions with Future Pumps Flows from PS 6, PS 7, PS 8, and PS 10 manifold along the Venetian Causeway before discharging into a 16-inch force main along Dade Boulevard, where they combine with flows from the Private PS. These Bows continue east along Dade Boulevard until they merge with Bows from PS 28 via a 42-inch force main. The combined flows are then conveyed south and discharged into the MDWASD system through the P.wc I 2606 of 3458 Hazen \larch 11, 200i Government Cut subaqueous crossing, which is owned by MDWASD. Once in the MDW ASD system, the flows are received at CDW WTP for treatment and disposal. Refer to Appendix K for pump station and force main locations, and Appendix L for a connectivity schematic of the City's pump stations. 6.2.2 Existing Hydraulics with Future Pumps A hydraulic analysis of the existing system conditions was conducted using the City's Infaworks [CM wastewater hydraulic model. The analysis reflects the current operational state in which the Private PS is actively discharging into the City's sewer system under existing (2025) flow conditions. The resulting peak velocity within the Private PS's discharge force main, which travels south along Purdy Avenue, is shown in Table 6.4. Velocities within the 6-inch discharge force main are anticipated to regularly exceed the minimum selfcleansing velocity of 2 fps. Table GA: Existing Conditions with Future Pumps • Fome Main Velocity Force Main Max Velocity (ftls) Private PS Discharge Force Main (64neh) 1 7,53 Table 6.5 presents the existing minimum and peak system conditions, along with the nominal average pump operating time (NAPOT) values for stations manifolded and downstream of the Private PS connection. Refer to Appendix M for the November 2024 NAPOT Report. With the future pumps, the Private PS has a capacity of 461 gpm with one (1) pump in operation, which is sufficient for the peak now of 95.1 gpm. This satisfies DERM's N+1 requirement, as the system operates with two (2) pumps, ensuring at least one additional backup component beyond normal operational needs. 2607 of 3458 Hazen %hr. h _ I .

By 2045, additional Bows from anticipated inflow and infiltration (1/1) and population growth must be considered, though the condominium itself is not expected to contribute to increased Bow. While hydraulic conditions are expected to remain largely unchanged, the primary difference is the system wide increased Bow volume. As a result, overall manifolded system pressures are expected to rise. The future conditions modeling analysis aims to confirm that the Private PS will have adequate capacity under these higher -pressure conditions. 6.3.2 Future Hydraulics with Future Pumps A hydraulic analysis of the future system with the future pumps was conducted using the City's Infaworks ICM wastewater hydraulic model. The resulting peak velocity within the 6-inch force main along Purdy Avenue was analyzed, as detailed in Table 6.6. Solids deposition in the force mains is not expected as the proposed peak velocities meet or exceed the industry standard scour velocity of 2.0 fps. Furthermore, these velocities remain below the maximum allowable force main velocity of 10.0 fps. Table 6.6: Future Conditions with Future Pumps - Force Main Velocity Force Main Max Velocity (hrs) Private PS Discharge Force Main (6-inch) I T44 Downstream and manifolded stations were analyzed. Minimum and peak system conditions for these stations are listed in Table 6.7 along with projected NAPOT values. These values demonstrate that all of the stations analyzed are expected to continue to operate below the 10-hour NAPOT limit. Additionally, 2608 of 3458 Hazen M",r _ the Private PS has adequate capacity to pump its peak flow of around 95 gpm in addition to satisfying the N+1 condition.

The flows are pumped through a 6-inch and 8-inch force main before discharging into an existing 16-inch DIP force main owned by the City of Miami Beach's (City) at the intersection of Dade Blvd and Purdy Ave. Currently, the private PS is having complications with the pumps failing and having to be replaced more frequently than typically necessary. The City incorporated the private pump station to its Master Sewer Hydraulic Model specifically to investigate if the force main replacement project currently underway at Dade Blvd has an impact on the PS at Purdy Ave. The analysis concluded that the force main replacement has a negligible impact on the private PS serving the Sunset Harbour Condominiums. Sunset Harbour Condominiums provided the head versus discharge curve (pump curve) for the pumps currently in use at the private PS on Purdy Ave, which is enclosed with this memorandum. The private PS was designed and constructed between 1994 and 1996 as shown in the Sunset Harbour Place Design Plans and in the as -built drawings attached. According to the design plans, the PS was designed to operate with a flow capacity of 375 gallons per minute at a total head condition of 137 feet (59 psi). The City charted the design conditions on most recent pump curve provided which shows that the designed head conditions are above the recommended pump curve. The existing pump curve does not align with the designed operating point which could indicate that the existing pumps are not the appropriate pumps for this application and can cause a pump to bum out or fail more frequently than the projected life expectancy.
