The Tequesta Village Council held a Village Council Workshop meeting at the Village Hall, 357 Tequesta Drive, Tequesta, Florida, on Tuesday, April 23, 1991. The meeting was called to order at 9:00 A.M. by Mayor Joseph N. Capretta. A roll call was taken by the Recording Secretary, Fran Bitters. Councilmembers present were: Mayor Joseph N. Capretta, Vice Mayor Ron T. Mackail, Earl L. Collings, and Edward Howell. William E. Burckart was not in attendance. Village Officials present were: Village Manager, Thomas G. Bradford; and Wendy Harrison, Assistant to Village Manager. Tom Hall, Water System Manager, and Bill Reese, Engineering Consultant, were also in attendance. II. APPROVAL OF AGENDA OPTIONS The Agenda was approved as submitted. III. DISCIISSION OF WATER PROJECTS BY STAFF Mayor Capretta. stated that the purpose of this Workshop is to determine the schedule of the water project, projected plans and present status, and establish a basis for future monitoring to determine whether the program is or is not on schedule. Village Manager Bradford explained that the project is called in-house the Wells and Tank Project. Internally, this project was divided into two areas for administration: 1) Tank, handled by Wendy Harrison, and 2) Wells and associated piping, handled by Tom Hall. An overview of the storage reservoir will be given today, as well as discussion of permitting, and the pipeline issue and the wells. Recycled Paper Village Council Workshop Meeting Minutes April 23, 1991 Page 2 ------------------------------- A) Storage Reservoir: Wendy Harrison gave an overview: The Storage Project began with a consultant selection process which took place in the summer of 1990. In October 1990, Reese Macon & Associates were selected to do the design work and construction observation for the Storage Reservoir. Reese Macon proceeded with programming and schematic design at that time, which was completed in January 1991. Some of the products of the programming process caused Village Staff to re-evaluate the Project. The projected Budget was in excess of budgeted funds. Therefore, the water system, and demand projection were re-studied. It was decided to scale back the Storage Tank from a three million gallon (3mg) tank to a two million gallon (2mg) tank. This also allows the option of room for an additional 2mg storage on the site. The Project is presently approximately 30 days behind schedule. The Project is presently at the 60~ Design process. The next step will be permitting. Design will be finished during Permitting. At the completion of Permitting, Construction will begin, scheduled to be completed by February 1992. Councilmember Collings asked how an estimate of a 3mg tank could change to a 2mg tank, and how could there be such an over-estimate of withdrawal or demand. Wendy Harrison explained that the original plan was 2mg. During the Budgetary process last year the point was made that as long as a 2mg tank was planned, why not build a 3mg tank. The 3mg tank was considered to allow enough storage in case the Village went to R/O. Tom Hall explained further that part of it was due to the fact of the estimated projected demand on the system for the next 5-10 years. A 2mg tank will bring total gallonage to 2.750mg available to be pumped under auxiliary power compared to the present .75omg. The storage supply will therefore be more than doubled. Vice Mayor Mackail felt the decision for a 2mg tank was an economic decision versus a long-term approach to the needs. Considering the Permitting process to be completed regarding Martin County and considering the demands for the next 5-10 years, it would be wise to make a decision that would warrant that. Economics are important, but it is also necessary to consider today's needs versus 5-10 years in the future. village Council Workshop Meeting Minutes April 23, 1991 Page 3 Wendy Harrison stated that demand projections were studied and it was discovered that the highest demand projections were for 8.Omgd in the year 2000. Those projections were made before the implementation of the tiered-rate structure. With the tiered-rate structure, demands have actually decreased from 1989 to 1990. A 2mg tank does allow sufficient storage. Mayor Capretta asked if the tiered-rate structure will eventually be eliminated when the drought is over. Village Manager Bradford stated it might need to be modified, but probably would never be eliminated. Mayor Capretta asked what brought about the decision for a 2mg tank. Bill Reese, of Reese Macon, explained one deciding factor was water quality. Water would sit in a 3mg tank too long before it gets out into the system. Another deciding factor was that when the existing 3/4mg tank was built, a 20- foot wall was built. Because of the hydraulics of the plant, the tanks will have to be kept at the same height; otherwise, overflow would take place. A 3mg tank with a 20-foot wall section is not an efficient design. Some of the economy of scale of going from a 2mg tank to a 3mg tank is not as much as it would be, otherwise. Regulations require that half of max-day (defined by plant capacity, plus what is purchased from Jupiter) usage be stored. That is calculated by projecting water usage to some point in the future, take half of that, to determine the amount of storage that is reasonable for now. It was the consensus of the Village Council that a 2mg tank would suffice for storage and budgeting purposes. village Council Workshop Meeting Minutes April 23, 1991 Page 4 ------------------------------- B) Permitting: Martin County Engineering - Roads - a U2 permit needed for the Village to do work with Martin County roads. It will also be needed if the Village attached to any Martin County bridges. Palm Beach County Engineering - Roads - a general permit needed for work with any Palm Beach County roads. DER - Well Sites - not a mandatory permit. Its purpose is to get DER to sign off on specific well sites. This needs to be done as early as possible. DER - Well Equipment ~ Piping - sFWMD - Well sites & CIIP (Consumptive IIse Permit) - Tequesta should already have this permit. The only significant thing about this one is that it does tie the Village in with the ability to move the well sites a few hundred feet without having to re-permit. PBCHD - Well Site, Well Equipment i Piping - DERM - Well Site - a Palm Beach County Agency, only to be involved if the well is in Palm Beach County. DER/PBCD/DERM - Release For IIse - Only applicable for Palm Beach County locations. It was the consensus to postpone plans to go before the Martin County Commission relative to outstanding issues until all applicable Martin County permits for this project are in hand. C) Pipeline: Tom Hall explained that Reese Macon has been authorized to begin Phase II (30$ Design) of the Wells, and most recently has been authorized to accelerate that process to Phase III (60~ Design) relative to the northern route, to get the permitting process underway. The northern route of the pipeline (i.e., County Line Road which would include Well 24 site - Psychiatric Hospital; Well 25 site - entrance to Turtle Creek; Well 26 within Turtle Creek; and Well 27 - adjacent to Country Club Drive), as opposed to the sub- aqueous route, regarding time and money, is thought to be more beneficial to pursue. The sub-aqueous crossing would cost between $90,000-$150,000 more than originally planned, with 5-8 more months of permitting time. Piping for the northern route would be substantially less expensive in both time and money. There is approximately a $100,000 difference between the two approaches. A 10"-12" pipe would be used for the northern route. The Village Manager reminded Mr. Reese of the need to provide pipes of a size sufficient to handle increased supply from existing proposed wells and new wells in the future. Mr. Reese assured the Village Manager that this would be calculated nd accounted for in pipe size determination. Village Council Workshop Meeting Minutes April 23, 1991 Page 5 ------------------------------- It was the consensus to pursue the northern route versus the sub-aqueous route as already chosen by Village Staff. D) Production Wells (24, 25, 26 and 27): Village Manager Bradford explained there is one decision not yet made: Well 24, next to the hospital could be done now and start the line from there to Seabrook Road which would give 300,000 extra gallons per day, the pro of which is water soon, and the con is economy of scale. Economy of scale (i.e., putting in a project of one well vs. four all together and length of pipeline of x number of feet vs. the whole line. Bringing the hospital well on line would bring the Village up to permitted capacity on the eastern peninsula. Councilmember Collings asked what the next step. Village Manager Bradford responded that the next step would be to obtain the permits and to decide within the next few weeks or so whether to break out Well 24. %I.
