FINANCE & ADMINISTRATION COMMITTEE MEETING • TUESDAY, NOVEMBER 21 , 1989 • • I . CALL TO ORDER AND ROLL CALL The Finance &. Administration Committee of the Village Council held a 'Committee Meeting on Tuesday, November 21 , 1989 , in the Village Hall , 357 Tequesta Drive , Tequesta, Florida. The meeting was called to order at 8 : 30 P.M. by Chairman Earl L. Collings . Finance & 'Administration Committee members present were : Mayor Joseph N . Capretta. Staff members present were : Thomas G. Bradford, Village Manager ; Wendy K. Harrison, Administrative Assistant to Village Manager; Bill C. Kascavelis , Finance Director. Others present were Richard Staudinger and Frank Reynolds , of Gee and Jenson Engineering Firm. II . APPROVAL OF AGENDA The Agenda was approved as submitted. • III . UPDATE ON SOUTH FLORIDA WATER MANAGEMENT DISTRICT PERMIT APPLICATION FOR ADDITIONAL WATER ALLOCATION FROM THE SURFICIAL AND FLORIDAN AQUIFERS . RICHARD STAUDINGER, P.E . Richard Staudinger capsulized the basis for this meeting: The original schedule was for Tequesta to receive the above-referenced permit by the end of September. Presently, seven weeks later, no permit has been received. The problem is drought . South Florida Water District asked .Gee and Jenson to do a model , a mathematical simulation, of what the aquifer does, how it responds to simulated rainfall and pumping conditions . Through computer software, Gee and Jenson is entering all of the boundary conditions which simulate a salt water body on three sides and a peninsula with an aquifer that is only re,-charged by rainfall . A certain amount of water falls on the peninsula, a certain amount is evaporated out , a certain amount is transmissivity - all . of those values are "calibration" . Those values can be adjusted for a mathematical model . Mr . Staudinger presented a mathematical grid of the model . Finance and Administration Committee Meeting Minutes November 21 , 1989 Page 2 Mayor Capretta asked why a small Village such as Tequesta would be required to do such a model . Mr . Staudinger explained South Florida Water District has other models but none are appropriate for the Village of Tequesta; therefore , one had to be created . South Florda Water Management wants to see well pumps in the aquifer as a drawdown so there is a net 1 foot fresh water mound, on each side, to prevent salt water intrusion . The more that is pumped down the less recharge there is and the cone of depression becomes bigger, making the fresh water mound fall even further . With today' s pumping conditions , there is a 1 1/10 of a foot water mound. Mr . Staudinger explained that Gee & Jenson is trying to show SFWMD, through this model , that the Village can double peak withdrawal on this peninsula and still maintain that net 1 foot fresh water mound, but it is not working . Hence, the argument regarding calibration, and the reason the permit has not yet been issued. Mr. Reynolds explained calibration: The model breaks up the section into cells and sections . Operating parameters between cells is provided, showing a starting point, and how the water runs . Calculations take place through all this , showing a minimum amount of difference between where the water was and the next step. Calibration involves adjusting the parameters within the cells , with the variables of transmissivity, storage , and adjusting boundary conditions . The paramaters can be adjusted to make the model show whatever you want it to , but that would not show exact conditions . SFWMD needs data for their records that shows that the water Tequesta is asking for is there . They need something acceptable for their records that meets their checklist . The model does not reflect the proposed hospital well or the proposed Rood Landscaping well . Mayor Capretta pointed out there are a lot of private wells around this peninsula over which the Village has no control - SFWMD controls that . Village Manager Bradford stated he had talked with SFWMD about the Village having more control over private wells and was told that is strictly SFWMD' s purview and legal action would be taken if the Village imposed. Mr. Staudinger stated SFWMD is willing to split the permit for withdrawal of R/O water right now and the Village can continue to haggle with them regarding surficial water . SFWMD is trying to limit the amount of water taken out of the surficial . • • Finance and Administration Committee Meeting Minutes November 21 , 1989 Page 3 Chairman Collings asked Mr . Staudinger what his recommendation would be . Mr. Staudinger responded that he would suggest splitting the R/O request and the surficial request . If the permit is kept together, then Gee & Jenson needs to work with the District to adjust the calibration to get the best yield, without making any radical changes . By getting the R/O permit split out , there still remains unclear direction regarding what will happen with the surficial aquifer, from the SFWMD point . Much of the plan remains unresolved. Mr. Bradford asked if there was any validity in telling SFWMD the Village wants private well systems to cease because the Village is of the opinion that it is adversely affecting the Village . Mr. Staudinger stated he would approach that subject with SFWMD. Mr. Bradford asked what the possibilities were of locating at the , "Country Club" peninsula, the new position being one fed by Encon ' s IQ water . Mr. Staudinger stated he would contact SFWMD to find out the mechanics of changing peninsulas . IV. COMMITTEE DIRECTION RELATIVE TO PERMIT APPLICATION ACTION PLAN The Committee summarized what they would like to see done . 1 . Not to split the water permit at all . Discover the status of pending applications . 2 . Pursue utilization of the existing peninsula to the maximum usage possible . 3 . Explore adding a well and annual allocation in the "Country Club" peninsula area. 4 . Don' t do anything with R/O because that permit will be procured, and based on whatever volume is available from the surficial , adjust the R/O to make up the difference . 5 . Mr . Staudinger will put together a scope on brine study. 6 . Check to see what the options are with private well regulation. • Finarc'e and Administration • Committee Meeting Minutes November 21 , 1989 • ' Page 4 V .
