INDIAN RIVER COUNTY, FLORIDA <br />INTER — OFFICE MEMORANDUM <br />TO: Vice Chairman <br />William C. Wodtke <br />Thru: Neil A. Nelson, <br />County Administrator <br />FROM: James -W. Davis, <br />County Engineer. 1)1P <br />DESCRIPTION AND CONDITIONS <br />DATE: June 2, 1981 FILE: <br />SUBJECT: Vero Shores Deceleration/Turning Lane <br />along Northbound US1 <br />REFERENCES - <br />The Department of Public Works has investigated the construction of <br />the above subject deceleration/turning lane. The Florida D.O.T. has stated <br />that.the following requirements are applicable: <br />1) Construct 125 lineal feet of storage lane <br />2) Construct 175 lineal feet of transition <br />3) Structural section to include 12" thick stabilized subgrade <br />8'z" of Limerock base, and 2" of D.O.T. Type 1 asphalt. <br />Mr. Gillick of the Florida D.O.T. is allowing an 11' wide storage <br />lane since the curve is super elevated and passenger vehicles are pre- <br />dominantly using this lane. This 11' minimum width is also a require- <br />ment of Federally funded roads which US 1 is included. A 12' wide lane <br />is usually required. <br />Also in lieu of constructing the 12" thick subgrade, a 12" thick base <br />course can be constructed over the existing subgrade material. This alter- <br />nate is permissible by the D.O.T. <br />ALTERNATIVES AND ANALYSIS <br />The following alternatives are presented <br />1) Construct an 11' wide storage lane 125 l.f. long and a 175' <br />transition lane <br />Approximate cost $6,050. <br />These costs are based upon verbal quotes from road building contractors <br />in the area. <br />2) Provide no relief to northbound US 1 motorists turning right <br />into Vero Shores Subdivision and allow an existing hazardous <br />situation to remain. <br />RECOMMENDATIONS <br />It is highly recommended that an 11' wide deceleration/turning lane <br />be constructed along northbound US Highway 1 in the vicinity of Vero Shores <br />Entrance at a cost of approximately $6,050. <br />JUN 31081 29 BobK PAGE 599 <br />1%7_ <br />
