I2 F. 2. <br />DEPARTMENTAL <br />INDIAN RIVER COUNTY, FLORIDA <br />BOARD MEMORANDUM <br />TO: Jason E. Brown, County Administrator <br />FROM: Richard B. Szpyrka, P.E., Public Works Director <br />SUBJECT: 58th Avenue (47th to 57th Street) Corridor Study / S.C.A.L.E. Report <br />DATE: December 20, 2019 <br />DESCRIPTION AND CONDITIONS <br />In 2004, the Board of County Commissioners (Board) approved a Development of Regional Impact <br />and accompanying Development Order with DiVosta, LLP for the construction of the Waterway <br />Village project. The boundaries of Waterway Village are roughly 49th Street to the south, 53rd Street <br />and the North Relief Canal to the north, 31St Avenue to the east and 58th Avenue to the west. As a <br />result of the impact of the development, DiVosta is required to make certain roadway improvements, <br />one of them being 58th Avenue. The Development Order requires DiVosta to expand 58th Avenue <br />from 49th Street to 53rd Street from 2 to 4 lanes with a divided median. Later in 2018, DiVosta and <br />the County amended the Development Order to require DiVosta to expand 58th Avenue to 4 lanes <br />from 53rd Street to 57th Street, with the County paying for the cost of design and construction of the <br />extended project. <br />Since. the segment of 58th Avenue expansion from 49th Street to 53rd Street was 100% developer <br />funded, the project did not need to be added to the Indian River County Long Range Transportation <br />Plan. In 2018, a roadway configuration by Kimley-Horn and Associates was presented to the Board <br />for this segment of 58th Avenue between 49th and 53rd Streets, which resulted in the Board approving <br />the following typical sections for 58th Avenue: <br />Between 47th Street and 49th Street Typical Section #106+00 to 111+10.24 70 to 132 -foot R.O.W. <br />(See Exhibit "A" attached) <br />Between 53rd Street and 57th Street Typical Section #111+10.24 to 175+80.00 130 -foot R.O.W. <br />(See Exhibit "B" attached) <br />In October 2019, Kimley-Horn completed 90% design drawings and their contract was amended to <br />include a corridor study / S.C.A.L.E. report. The study evaluated five (5) factors in determining the <br />most feasible roadway alignment. The five S.C.A.L.E. factors are as follows: <br />• Safety <br />• Cost <br />• Alternative Alignments <br />• Long Range Planning <br />• Environmental Considerations <br />153 <br />
