INDIAN RIVER COUNTY, FLORIDA <br />MEMORANDUM b E <br />TO: Jason E. Brown, County Administrator <br />THROUGH: Richard B. Szpyrka, P.E., Public Works Director <br />FROM: James W. Ennis, P.E., PMP, County Engineer <br />SUBJECT: Roadway Network Safety Proposal: Installation of Cul -De -Sac on 12th <br />Avenue and Removal of Connection to 1st Street SW <br />DATE: January 11th, 2018 <br />DESCRIPTION AND CONDITIONS <br />Over the past 5 -years the Public Works Department has noted that 6 incidents have occurred <br />where vehicles have left the roadway and entered the canal that is parallel to 12th Avenue <br />(unpaved) between 1st St. SW (paved) and 2"d St.(paved). Departures from the roadway at this <br />location are particularly dangerous as this canal directly connects to the South Relief Canal and <br />is in excess of 15 feet deep. Additionally, the canal slopes at this location exceed a 1 to 1 ratio <br />which is considered non-recoverable for passenger vehicles. <br />After a review of the roadway geometry, available right-of-way, and accident report details at <br />the intersection of 12th Avenue and 1st St. SW it was determined that the most cost-effective <br />solution to improve roadway safety is to close 1St St. SW at 13th Avenue and install a cul-de-sac <br />at the southern end of 12th Ave. As a result of this change traffic previously traveling to and <br />from 1st St. SW will have the opportunity to use 13th through 18th Avenues resulting in <br />negligible impacts in distance travelled to and from their destinations. This should also result in <br />a reduction in traffic volumes, and subsequently maintenance grading requirements, along the <br />unpaved section of 12th Avenue. The estimated cost for this project is $20,000.00. <br />FUNDING <br />Funding is available for the necessary improvements to implement this road closure in <br />Miscellaneous Intersection Improvements -Account No. 31521441-066510. <br />RECOMMENDATION <br />Staff recommends that the Board of County Commissioners approve the closure of 1st St. SW at <br />13th Avenue and construct a cul-de-sac at the southern terminus of 12th Avenue <br />ATTACHMENT <br />Proposed Roadway Re -alignment and Cul -De -Sac Plan Sheet <br />APPROVED AGENDA ITEM FOR JANUARY 23, 2018 <br />49 <br />F:\Public Works\ENGINEERING DIVISION PROJECTS\1723 12th Avenue & 1 st Street SWU-Admin\Agenda Items\IRC-1723_BCC Memo_I2th Closure.doc <br />
