Call to Order Mayor McElyea called the workshop to order at 6:30 p.m. 2. Roll Call: Present: Mayor: C.K. McElyea Vice-Mayor: Bob Mikes Commissioners: Bob Anton Robert Chunn Pat Flury City Attorney: Tom Ansbro City Manager: Ivan Pato City Clerk: Louise Stilson 3. Presentation of"City of Dania Beach — Proposed 1.5 Million Gallon Water Storage Tank" (Fernando Vazquez, P.E., Public Services Director) s Fernando Vazquez, Director of Public Services, introduced Fred Bloetscher from Public Utilities Management and Planning Services, Inc. and stated that the purpose of the workshop was to bring to light issues concerning the upcoming water storage tank. He reported that the water supply projections anticipated 2.4 MGD (Million Gallons per Day) and that the future demands were 3.6 MGD. He indicated that the City needed to accommodate this future demand as well as fire flows. Director Vazquez stated that the storage requirements were based on an initial letter from Broward County Department of Health (BCDOH) that required a two million gallon storage tank based on future requirements, but following negotiations with them the tank size was reduced to one and one half million gallons. He reported that the previous tank location was evaluated and through an engineering technical assessment, they determined that the location preference was the Water Treatment Facility. He noted that a study determined that an elevated tank was too large for the existing site. Director Vazquez stated that they were working on a hydraulic model of the system, but at this time it was undetermined as to whether or not an elevated tank was necessary. He explained that other considerations were the potential encroachment on FEC right of way, the provision of an overflow area, height, and power line hazards. He noted that it was important to have a site that provided adequate room for construction, staging, and maintenance operation. Director Vazquez felt that it was not necessary to have an elevated tank in a remote area. He stated that remote access created a problem with emergency operations and security. He indicated MINUTES 1 JUNE 8, 2004 WORKSHOP MEETING —WATER STORAGE TANK is that the Water Treatment Facility met all the location requirements and noted the question was s whether to have an elevated or ground storage tank. Director Vazquez felt the advantage of an elevated tank was that it did not require pumps as long as certain pressure level was maintained. He explained the disadvantages were the cost of tank, the cost of construction, FAA permit requirement, height, maintenance, inspection, and rustproofing. Director Vazquez noted that ground storage tank advantages included the lower cost of construction, lower height, lower maintenance, simplified water testing, less intrusive aesthetics, and more easily attained high security measures. He explained that the disadvantages were the lack of water pressure and the requirement of a larger area to accommodate base. Director Vazquez outlined the construction costs as $750,000 for a ground storage tank and $2,000,000 for an elevated tank. He reported that 10-year maintenance costs were estimated at $70,000 for a ground tank and $140,000 for an elevated tank. He concluded the presentation by noting that neighboring cities used ground storage tanks and that two of them additionally used elevated tanks. Director Vazquez recommended building a ground storage tank on existing water treatment plant site based on capital, operation and maintenance feasibility principles, maintaining an aesthetically pleasing value to the community, and security reasons. In response to Commissioner Anton's question concerning the reliability of pumps to maintain water pressure to homes in an emergency situation, Director Vazquez explained that elevated • tanks still needed booster pumps to get water to serviceable area and noted that diesel pumps were currently used for this purpose with emergency generators. Commissioner Anton questioned the difference between the cost of BCDOH's original two million gallon tank recommendation and the reduction to a one and one-half gallon tank. Director Vazquez noted the difference was $.30-$.40 per gallon. In response to Commissioner Anton's question on whether it was safe to go with a one and on- half million gallon tank, Director Vazquez stated that a two million gallon tank was too large even for the projected 33 percent increase in residents. Commissioner Anton felt that maintaining the security of one location was much easier to accomplish. Vice-Mayor Mikes noted that this proposed tank was six times as big as the current tank and felt it was adequate. Director Vazquez reported for Vice-Mayor Mikes that the interconnects with Hollywood were 8 & 12 inches and noted that the cost for a totally redundant pump system was $250,000. He noted that the current system needed repairs. Fred Bloetscher felt FPL should be contacted about current power feed. Vice-Mayor Mikes felt comfortable with a ground tank and a completely redundant pumping system and also suggested enhancing the connection with Hollywood. MINUTES 2 JUNE 8, 2004 WORKSHOP MEETING —WATER STORAGE TANK Director Vazquez noted that the contract with Ft. Lauderdale was due for renewal and was only to be used under emergency conditions. Commissioner Flury agreed with Vice-Mayor Mikes on the ground tank, but felt that the ground tank should have a pleasing design and asked City Manager Pato about the RFP for an elevated tank. Fred Bloetscher stated that he preferred ground storage tanks for Florida. City Manager Pato clarified that SRF funds would cover the design/build plan and that approval of up to $2,000,000 had been granted. Director Vazquez noted that there would be a new interconnect with Hollywood on Sheridan Street. In response to Commissioner Chunn's question regarding the need for larger pumps, Director Vazquez stated that larger pumps were not necessary at this point. He explained that they could not pressurize the system any higher because they were unsure of the condition of the tanks on Stirling Road. Director Vazquez noted that he was looking for direction from the Commission. The Commission consensus was in favor of the ground storage tank. • 4.
