Project Location

3Project BackgroundIdentified as a needed project in 2005 Tower Road Network Study. Identified as major project need in the recently adopted Mobility Plan. Design funded with $540,000 of Transportation Trust Fund.

Because it was anticipated that this project would have the potential to be eligible for State Funding, the design is done in compliance with the State criteria and specific studies must be performed.4Study PurposeDetermine need to improve safety and add capacity on SW 20th Ave. from SW 61st St. to SW 62nd Ave.Based upon the established need develop alternatives to satisfy the need.Evaluate identified alternatives relative to environmental impacts and costs.Submit Draft Project Development Summary Report (PDSR) to FDOT for review and comment.

Because it was anticipated that this project would have the potential to be eligible for State Funding, the design is done in compliance with the State criteria and specific studies must be performed. First, a determination needed to be made that the project would improve safety and add capacity on SW 20th Ave. from SW 61st St. to SW 62nd Ave. Once the need is established, staff needs to develop alternatives to satisfy the need. Then you must evaluate the identified alternatives relative to environmental impacts and costs. Once the study is complete, we will submit a draft to the FDOT for review and comment. After the FDOTs comments are addressed we will bring the study to the Board. After BoCC comment, we will conduct a public alternatives meeting where we will solicit public comment on the identified alternatives. We will then select a preferred alternative and present to the MTPO subcommittees, BoCC, and MTPO. We will then present the preferred alternative for public comment in a public hearing. Once we finalize study recommendations , we will then submit is for FDOT approvalThe Study activities include:Conduct deficiency analysis Evaluate historical crash data Evaluate capacity Evaluate multi-modal accommodation Develop project purpose and need Develop alternatives Evaluate bridge I-75 overpass bridge and screen bridge alternatives Develop roadway approach configuration based upon selected bridge alternative Conduct environmental evaluation of alternatives Cultural Resources Air & Noise Wetlands Biological Assessment Floodplains Other Develop costs Conduct comparative analysis Develop Draft Project Development Summary Report (PDSR) The anticipated project schedule is:Conduct Alternatives Public Meeting (Spring 2012)Select preferred alternative (Summer 2012) Conduct Public Hearing (Summer 2012) Develop Final PDSR (Fall 2012) Secure FDOT approval (Fall 2012)

5Study PurposePresent to the BoCC the PDSR with the identified alternatives.Conduct a Alternatives Public Meeting to solicit public comment on identified alternatives.Present to the BoCC and MTPO.Hold a public hearing to present the preferred alternative.Finalize study recommendations and secure FDOT approval.
