BOOK 93 PnE 28 <br />ON MOTION by Commissioner Macht, SECONDED by <br />Commissioner Eggert, the Board unanimously approved <br />the contract with F.I.T. in the amount of $36,847, <br />as recommended by staff. <br />CONTRACT IS— ON FILE IN THE OFFICE OF THE CLERK TO <br />BOARD <br />CONTRACT ADDENDUM WITH UNIVERSITY OF FLORIDA - PEP <br />REEF PHYSICAL MODEL <br />The Board reviewed the following memo dated 7/27/94: <br />TO: James E. Chandler, <br />County Administrator <br />THROUGH: James W. Davis, P.E., - <br />Public Works Director <br />FROM: Don G. Donaldson, P.E., Coastal EngineelyiD. <br />SUBJECT: Indian River County/Vero Beach Breakwater <br />University of Florida Physical Model Contract <br />DATE: July 27, 1994 FILE: U0nWD]M.A= <br />DESCRIPTION AND CONDITIONS <br />Staff has received a draft report of the physical model studies by <br />the University of Florida (UF). The OF conducted a physical model <br />test to evaluate four separate breakwater arrangements at four <br />water depths, including a no breakwater case (see Attached). The <br />results clearly demonstrate the breakwaters ability to reduce wave <br />heights. They also indicate that a continuous alignment can <br />increase the longshore current. The staggered case (Case C) was <br />thought to provide the best chance of wave height reduction without <br />the increase in,currents. However, the results suggest that the <br />staggered units were too close and the segments were too short. <br />Staff and the OF feel that the three -segment configuration (Case B) <br />had the least impact to longshore currents. However, the gaps <br />provide too much wave transmission. The best configuration is <br />likely to be a long segment, staggered breakwater. The OF has <br />agreed to test this configuration and include the result in the <br />report. The cost for this additional testing is $2,500.00. <br />RECOMMENDATIONS AND FUNDING <br />Staff recommends that the board authorize a contract addendum to <br />the University of Florida in the amount of $2,500.00 for the <br />additional testing. Funding is from Tourist Tax Revenue account <br />119-144-572-067:63 <br />28 <br />August 2, 1994 <br />r � <br />i <br />
