Description of Project

Project Location Map

The project limits of CR-714 / Martin Highway are from just west of the SR-714 / Turnpike Entrance to just west of Mapp Road. The corridor is owned and maintained by Martin County. The main scope of the work is to widen/reconstruct the existing two-lane undivided rural roadway to a four-lane divided urban roadway with bike lanes on both sides, signing and pavement markings, upgrade existing signalized intersections to mast arm signals with pedestrian features, add a new signal at the eastern Hidden Oaks Middle School Entrance, decorative lighting, and landscape enhancements. In addition, a 12 ft tall decorative noise abatement wall will be installed on the north side of the corridor, adjacent to the Sunset Trace development. The eastern end of this project will connect to segment 1 (Indian Street Bridge Project) and will serve as the last segment in providing a continuous four-lane corridor from the Turnpike to US-1.

Activities performed through January 2013

Roadway and Drainage Design:

  • FDOT and Martin County performed a joint Value Engineering Study which resulted in design recommendations and alternatives to improve the value and cost of the project.
  • Commenced with the design of the proposed roadway. Design elements including travel lane and median widths, horizontal and vertical alignment of the roadway, land acquisition identification, and pedestrian features including sidewalk and bike lanes.
  • Commenced with maintenance of traffic design for construction of the project.
  • Commenced layout of the proposed drainage system including 2 pond sites

Permitting:

  • Commenced identification of wetlands and protected species within the project limits.
  • Permit package/application for the proposed project submitted to South Florida Water Management District for review and approval on January 24, 2013.

Utility Coordination:

  • Conducted Pre-Design Utility Kickoff Meeting.
  • Identified utility owners that have facilities within the limits of the project.
  • Initiated coordination with utility owners to obtain markups of the locations of their existing facilities and as-builts.
  • Designation of existing utilities performed within the limits of the project and SUE activities.
  • Conducted Initial Engineering Utility Coordination Meeting with utility owners.
  • Identified potential conflicts between proposed features and existing utilities.

Signalization:

  • Commenced signalization analysis and design for the mast arm upgrades at the intersections of CR-714 with Martin Downs Blvd and the Florida’s Turnpike Entrance, SW High Meadow Avenue, SW Berry Avenue, SW Palm City School Avenue, and SW Whispering Sound Drive and design for the newly proposed signal at the east entrance of the Hidden Oaks Middle School.
  • Commenced design of illuminated overhead street name signs for all intersections and preparation of signalization plans for all the intersections.
  • Commenced design of the proposed fiber optic network improvements and the interconnect plans for the corridor.
  • Conducted coordination meetings with Martin County regarding the proposed signalization improvements and improvements to the Martin County fiber optic network within the limits of the project.

Lighting:

  • Commenced lighting analysis and preparation of lighting plans.
  • Proposed decorative lighting will be of a similar aesthetic to segment 1 (Indian Street Bridge Project).
  • Coordinated with Martin County regarding the proposed decorative lighting design.

Miscellaneous Structures:

  • Commenced concrete box culvert analysis and design for the replacement of the existing dual barrel drainage culvert at Danforth Creek.
  • Commenced data collection activities for the preparation of the noise barrier study throughout the corridor.
  • Potential noise barrier location is on the north side of the roadway, east and west of High Meadow Avenue.

Landscape:

  • Commenced landscape/hardscape/irrigation analysis and the preparation of landscape plans.
  • Coordinated with Martin County regarding the proposed landscape design.

 

Activities performed through April 2013

Roadway and Drainage Design:

  • Continue design of all features including roadway horizontal and vertical alignment, adjacent property access and tie-ins, pedestrian features, drainage inlet/pipe layout, and pond design.
  • Continue the design for the phasing of construction including lane configurations, pedestrian access, and temporary drainage.

Permitting:

  • Continue coordination with South Florida Water Management District including wetland identification and mitigation, drainage and pond design, and protected species identification.

Utility Coordination:

  • Finalize subsurface investigation at potential conflicts between proposed mast arm foundations and existing utilities.
  • Utility owners to verify their existing facilities are accurately represented in the Initial Engineering plans. (Location, size, type, configuration)
  • Identify potential conflicts between proposed drainage system and existing utilities.
  • Perform subsurface investigation at potential conflicts between proposed drainage system and existing utilities.
  • When the Constructability Plans are submitted, a conflict matrix will be generated and that information along with the subsurface investigation information will be provide to the utility owners.
  • Utility owners will engineer their relocation \ adjustment designs for inclusion in the Final design plans and agree to work schedules to perform the relocations and\or adjustments.

Signalization:

  • Continue coordination with Martin County regarding the proposed signalization improvements and improvements to the Martin County fiber optic network within the limits of the project.
  • Coordinate, as necessary, with utility owners, regarding their relocation intents, to proceed with signalization design and production without delays.
  • Continue signalization analysis and design and preparation of signalization plans for all the intersections.
  • Continue design of the proposed fiber optic network and the interconnect plans for the corridor.
  • Include measures in the both the signalization design and fiber optic network design for maintaining existing connectivity within the corridor through all phases of construction.

Lighting:

  • Continue lighting analysis and preparation of lighting plans.

Miscellaneous Structures:

  • Continue concrete box culvert analysis and design for the replacement of the existing dual barrel culvert at Danforth Creek.
  • Commence noise barrier design and preparation of structure plans.
  • Coordinate with Martin County regarding design and aesthetics of proposed noise barrier wall.

Landscape:

  • Continue landscape/hardscape/irrigation analysis and the preparation of landscape plans.

Public Involvement:

  • Continue preparation of various presentation materials for Public Involvement Meeting.
  • Conduct Public Involvement Meeting (March 13, 2013).
