<br />developed and supported, including preparation of presentations
<br />for City review and community engagement. Participation in
<br />the 100 Resilient Cities Workshop resulted in direct design
<br />enhancements. An arborist was utilized to identify and evaluate
<br />the existing tree canopy within and adjacent to the right-of-way
<br />to preserve existing green infrastructure where feasible.
<br />Encroachment reviews and optional design considerations were
<br />conducted to resolve conflicts, resulting in harmonization plans
<br />for 137 properties. Each property plan set included a site plan,
<br />landscape plan, and 3D perspective rendering. In addition, three
<br />existing City and FDOT stormwater pump stations that interface
<br />with the project were evaluated for emergency generator
<br />locations and connections, supported by supplemental surveys
<br />and site investigations to enhance system resiliency.
<br />Utility coordination included collaboration with 18 utility
<br />providers along the project right-of-way to identify existing
<br />facilities, conflicts, and opportunities for relocations or
<br />adjustments. A Master Utility Plan was created, developed, and
<br />maintained to integrate and remediate affected utilities. Using
<br />Civil 3D software, a detailed 3D utility model and interactive
<br />video were developed to represent existing and proposed
<br />subsurface conditions, minimize conflicts, and improve utility
<br />corridor planning.
<br />Stormwater Drainage System: Improvements include review and
<br />evaluation of two existing hydraulic models and development
<br />of an updated Stormwater and Hydraulic Model for the West
<br />Avenue Project Basin, encompassing approximately 600 acres
<br />extending east to the Atlantic Ocean. Modeling was performed
<br />using ICPR4 and included upsizing of drainage lines, curb
<br />inlets, and yard piping, along with significant upsizing and
<br />modifications to proposed pump stations. Pre- and post-
<br />construction scenarios and three alternative stormwater models
<br />were developed, accounting for proposed roadway elevations
<br />and existing finished floor elevations. A hydraulic grade line was
<br />developed and maintained at one foot below the lowest finished
<br />floor elevation.
<br />The project includes replacement and upsizing of the stormwater
<br />drainage system including 3,600 LF of 24-inch RCP drainage,
<br />2,100 LF of 48-inch RCP drainage, 800 LF of 60-inch RCP
<br />drainage, 2,300 LF of 72-inch RCP drainage, 400 LF of 84-
<br />inch RCP drainage, and 300 LF of 96-inch RCP drainage, with
<br />equivalent box culvert alternatives considered. Additionally, a
<br />new 120,000 GPM stormwater pump station, including water
<br />quality treatment units and a specialized dissipator discharge
<br />structure, will be installed on the west end of Lincoln Road.
<br />Water Distribution and Transmission System: Improvements
<br />include replacement of existing water mains, including 1,150
<br />LF of 6-inch fire service lines, 7,350 LF of 12-inch distribution
<br />main, and 3,000 LF of 20-inch transmission main. New service
<br />connections, meters, hydrants, and irrigation lines will be
<br />installed, and existing water mains will be decommissioned. The
<br />new system will be installed along West Avenue, between 14th
<br />Street and Lincoln Road, along Bay Road between Flamingo Way
<br />and the Collins Canal, and along 14th Terrace to Lincoln Road
<br />between West Avenue and Alton Road.
<br />Sanitary Sewer Collection System: Improvements include
<br />rehabilitation and/or replacement-in-kind of the existing
<br />collection system along with adjustments to slopes and
<br />manholes, with replacement of 5,400 LF of pipe ranging from
<br />12-inch to 18-inch diameters and 32 manholes.
