Title
State Road 329 (Main Street) Reconstruction (NB)
Staff recommends executing two Utility Work by Highway Contractor Agreements with Florida Department of Transportation for State Road 329 (Main Street) reconstruction.
Explanation
Florida Department of Transportation (FDOT) will be resurfacing and reconstructing State Road 329 (Main Street) from Depot Avenue to Northwest Eighth Avenue converting a four-lane roadway to two lanes with center turn lane, bike lanes, on street parking, and mast arms at the signalized intersections. FDOT will also be installing a new storm water collection system as part of the roadway reconstruction. Planning and design have occurred for 10 or more years on this project with a number of design options considered, and with a range of requirements for utility relocation. Prior to the current design iteration, the design completed in 2003 by FDOT would have allowed GRU to salvage some portion of the gravity sewer instead of a total relocation/rebuild as currently required.
An environmental assessment of the reconstruction corridor was completed in October 2008 by a consultant to FDOT. The assessment found contamination from multiple chlorinated solvent and petroleum plumes present beneath the project corridor from Depot Avenue to Southwest Third Avenue. FDOT proposes that GRU be responsible for incremental remediation costs associated with relocation of GRU facilities. Water/Wastewater Systems is responsible for water and wastewater facility relocation work associated with the roadway improvements. The water system work will include a new 16-inch ductile iron water main from Depot Avenue to University Avenue, including new water services and fire hydrants. The wastewater system work will include a new 12-inch PVC gravity sewer main from Depot Avenue to Southwest First Avenue, including new service laterals. Based on the final design of the utility relocation and remediation costs, the project is more costly than a...
