BOARl2~ERS : Harry Reid, Vice-Chairman, Absent James Greene, Chairman, Present Richard Tiffany, Present Terri Donnelly, Absent Tim Johnson, Present CITY OFFICIAL: D. LeBlanc, Land Dev. Coordinator L. Kozlov, City Engineer ~~oval of Minutes of Sept~nber 7, 1989: Greene asked the Board if there were any questions, carunents or corrections to the minutes. There were no questions, comments or corrections. The minutes stand approved as distributed. Request of ABC Liquors, Inc., for a Variance to Section 9-241(d) , to Allow a Retention/Detention Pond Bottom Elevation to be Less Than One ( 1) Foot ( 12 inches) Above the Seasonal High Ground Water Elevation. The Property is Zoned C-1 (Neighborhood Co~nercial District) and is Located at 901 W. State Road 434 ~!i Corner of SR 43_Lang Belle Avenue) : _ LeBlanc stated that the Board has received the packet of information regarding this request. A public notice was advertised in the Seminole Sentinel advertising this request. Also, property owners within 150 feet of the property were notified. LeBlanc stated that the City Engineer is present for any questions and Steve Helle, project engineer, James Johnson, director of construction and n~inte~~e, for ABC Liquor are present for any questions. Helle stated that the owner intends to build an ABC Liquor Store. The developer plans to move and enlarge the driveway onto Belle Avenue. The retention pond to the rear of the site one reason is to keep the intersection away fran Belle Avenue. Where we propose the retention pond is on the up hill side. To make the hydraulics work, the retention pond will have to be dug fairly deep. The bottom of the pond is approximately 1 to 1 1/2 feet above the expected wet season high water table. With no provisions made the retention pond would be wet a good part of the year. To accommodate that we will put underdrains around the up hill side of the pond. There underdrains will have two purposes; one is to drain off the percolated water which comes from rain fall which will go into SR 434 stormwater system. The second purpose is to control groundwater in the vicinity of the retention pond to be below the bottom of the pond. Helle stated that this system is typical of most systems in the area. We have designed this pond in accordance with the St. John' Water Management criteria. Helle stated that the St. John's Water River Management District has approved Board of Mjustment October 5, 1989 Page 2 the plan and the Florida Department of Transportation (FOOT) has verbally approved the plan. Greene asked hOW" deep is the bottom of the pond from the paving of Belle Avenue. Helle stated that the bottom of the pond would be eight feet below the paving. Johnson asked what is the reason for putting the pond in this location. Helle stated that traffic flow thru, with putting the entrance on the other side it would be too close to the intersection of Belle Avenue and SR 434. Johnson asked if the pond was put in the front, how deep would it be. Helle stated that if the pond was in the front the depth would be from three to five feet. Greene asked how high the wall will be around the retention pond above grade. Helle stated that the bottom of the wall will range from three feet to five and one-half feet. Greene asked about the abutting property. Helle stated that behind the property is vacant and to the western side of the property is an existing carunercial building. Kozlov stated that the City has an ordinance is a tighter refinement of the Water Management requirements. A previous engineer for this site had designed the pond in the front and it did not use underdrains. Mr. Helle has taken over and redesigned the pond. Kozlov stated that the design does not meet the Code because of the one foot pond bottom, other that it meets the code requirements. He stated that ponds such as this in Winter Springs has an adverse effect because of the high water table in the City. Greene asked about clean outs of the underdrains. Helle stated that there will be clean-outs at every bend. A new requirement of the Water Management District is that on all underdrain systems designed a registered engineer has to visually inspect the construction of the underdrains. Every year these underdrains must be inspected and certified to say that the underdrains work. Kozlov stated that there is an opportunity to design this pond to the City Code. Tiffany moved to deny the proposal. Seconded by Johnson. Vote: Johnson: aye; Greene: aye; Tiffany: aye. Motion approved. The meeting was adjourned at 7: 30 P.M.
