Case Number ARB2016-00004—738 Highland Avenue—Park Lake Townhomes
From the Applicant: The City of Orlando proposes to construct a new pedestrian bridge, and associated approach ramps, to span over Colonial Drive (SR-50) and provide bicycle and pedestrian connectivity between the Gertrude's Walk and Dinky Line segments of the Orlando Urban Trail. The Central Florida Commuter Rail Corridor runs north and south through the project area, and will be located adjacent to the trail and pass beneath the proposed pedestrian bridge. The pedestrian bridge is proposed to be approximately 200 feet long and cross over Colonial Drive diagonally across the roadway and rail lines below. The approach ramps start at grade at the north and south extents of the project limits and elevate to the bridge crossing, with a proposed combination of on-grade construction and MSE-wall retained earth, and elevated structure supported on single column piers. The approach ramps will be aesthetically consistent with the nearby I-4 Ultimate project. The bridge span is comprised of a box truss assembly, supported by a monumental main pylon on the south side of SR-50, and by smaller piers at the extreme north and south ends. Stay cables are also utilized for secondary support of bridge live loads. The City of Orlando has contracted with Southland Construction, Inc. to deliver the project via a Design/Build delivery model. Horizon Engineering is providing Civil and Structural Engineering services for the D/B team, and HKS Architects, Inc. is providing Architectural Design services. The project is scheduled to commence construction in the first quarter of 2017.
ARB Staff would like to recognize the applicant and their design team for their collaborative efforts with City, ARB and DDB Staff in the initial design of this signature downtown project. This pedestrian bridge will not only connect two major trails and provide pedes-trians and cyclists a safe passage across one of the most dangerous roads in Central Florida, but it will also become a highly visible gateway into the Downtown area during the day and night. ARB and DDB Staff have been deeply involved in this project attending numerous meetings, and making significant design decisions including: the finish and material of the bridge truss, lighting options, and how the bridge interfaces with the streetscape. It is diffi-cult to provide anything more than basic conditions of approval for this project because it is difficult to question any of the design decisions after exploring numerous options. This project is the best it can be because of the complete and comprehensive design process it has been through to get to this point. Staff believes that this project will provide significant benefits and will be a visual landmark in Downtown Orlando for years to come. December 2016 Update At the November 2016 ARB meeting, the Board deferred action on this application and requested additional design detailing and information on several elements. Those elements and the applicant’s response to the design concerns are detailed below: Pier Design—The ARB members requested additional attention to the design of the ramp piers leading up to the truss structure that crosses Colonial Drive. The board felt the proposed smooth concrete was too plain and uninteresting. The applicant has proposed two alternative treatments that add a fractured fin textured area to the columns that creates the desired detail and interest on the approach ramp piers. The applicant also investigated re-designing the pier structures. This was deemed unfeasible and financially responsible by the deign team, DDB, Public Works and ARB Staff. A new pier design would create a significant setback to the project schedule because the structural engineering of the approach ramps would have to be completely re-done. Additionally, the costs involved in the re-engineering effort, construction delays to the schedule, and increased fabrication requirements would create a substantial cost over run to the current, fixed budget for the pedestrian overpass. Paint Colors—The ARB members felt the proposed paint colors on the Colonial Overpass should not match the paint colors being used on the I-4 Ultimate structures. The board felt the paint colors should be unique to the pedestrian overpass structure. The applicant has proposed a warm light and warm dark gray color palette instead of the original light and dark tan paint colors that matched the I-4 structures.

P RO J E C T O V E RV I E W [ C O N T . ] Truss Mesh—The ARB members requested additional information on the visual characteristics of the required interior mesh on the truss structure. The applicant has provided some additional details on the mesh, as well as an example of an existing pedestrian bridge at Disney Springs which incorporates the same mesh. Truss Head Walls—ARB members expressed security concerns about the solid head walls on the north and south ends of the truss structure. The applicant clarified that the north headwall is separated from the at-grade pedestrian paths by a security fence. The south head wall is actually located in the middle of an FDOT retention area and is significant distance from any of the trail treads. Pier Lighting—The applicant investigated extending the color changing LED accent lighting and reveal to the top of the main piers on the south side of Colonial. In order to accomplish this, the entire pier structure would have to be thickened from top to bottom with as much as 12-inches necessary at the base of each pier. The design team and ARB staff felt that increasing the mass of the pier structure would adversely impact the aesthetic qualities of the pier by making it look heavier and bulkier. Additionally, it was deter-mined that the cost increase to achieve such a minor aesthetic change was not practical. Anti-Vandalism Coating—The use of an anti-vandalism coating on the exposed bridge and ramp surfaces was investigated further and determined to be unnecessary. Chemical removers can be used on the metalized finishes of the truss structure and railings to re-move paint tags without harming the finishes. The pier structures can be re-painted if vandalized and paint tags on the main bridge piers, which are sandblasted concrete, can either be removed by sand blasting or with chemicals.
ARB and City Staff has reviewed the Applicant’s submittal documents and has the following conditions of approval: 1. Streetscape
A. Streetscape Design Guidelines All at-grade streetscape design and construction is required to comply with the design, material and construction re-quirements of the Downtown Orlando Streetscape Design Guidelines, as they may be amended from time-to-time, and the conditions in this staff report.
B. General Streetscape Requirements: i. At-Grade Street Lights – Single acorn 40-watt LED streetlights, consistent with the Downtown Streetscape Design
Guidelines and spaced based on OUC lighting requirements shall be installed at the plaza area on the south side of Colonial.
ii. Pedestrian Plaza—The Lawerenceville brick surface of the plaza area at the south side stair landing shall be re-placed with gray concrete on a 5-foot by 5-foot grid with troweled edges and a medium broom finish.
iii. Valve and Junction Boxes—All at-grade junction, valve and control boxes shall be traffic bearing grade boxes and lids, painted per the downtown streetscape standards.
2. Architecture A. ARB Staff supports the architectural direction, theme and materials of the Colonial Overpass project. B. Vandalism—It is recommended by ARB Staff that an anti-vandalism coating be applied to all reachable surfaces. C. Benches — Benches in the plaza area shall have a center divider to prohibit the ability to recline or lay down on the
benches. D. Final architectural plans, elevations, materials and finishes shall be reviewed by ARB Staff prior to commencement of
construction to ensure consistency with the ARB approvals.
3. Lighting Plan — A lighting plan that complies with the City’s lighting regulations [Chapter 63 2M.] including photometrics and all proposed exterior lighting fixtures shall be submitted for ARB Staff review prior to issuance of building permits.
4. Modifications — Minor modifications to the approved ARB plans will require ARB Staff approval prior to construction or in-
stallation. Substantial modifications may require a return to the full ARB for review and approval. 5. Permit Approvals
A. Signage—All signage shall be submitted to ARB staff for review prior to submittal of sign permits. B. ARB Approval — ARB Approval does not grant permission to construct or install. All necessary permits must be obtained
prior to commencement of construction activities.
