~=~ Kimley-Horn and Associates, Inc. Mr. Ken Jeffries, June 9, 2011, Page 2 within the study areas from 3:00 p.m. to 7:00 p.m. on January 27,2011 (Thursday) and from 11 :00 a.m. to 3:00 p.m. on January 29,2011 (Saturday). The data is summarized in Attachment E. As indicated, over 175 pedestrianslbicyclists cross at study area's unmarked crossings during the weekday peak period and over 250 users cross this area during the weekend peak period. It should also be noted the Pier Park is located immediately east of the study area. This public park is a significant pedestrianlbicyclist traffic generator. Pedestrianlbicyclist crash data was also collected and reviewed as part of this project. A total of five crashes were reported between 2005 and 2009. Four (4) crashes occurred on SR Al A and one crash occurred on westbound SR 826. All crashes resulted in injuries. Four (4) crashes occurred during daylight conditions and one (1) crash occurred during dark conditions. Crash locations are summarized in Attachment F. Conceptual Plan The conceptual plan is provided as Attachment G. Note that, beyond the construction of additional sidewalk network, the plan also recommends the removal of the existing substandard brick paver paths, as shown in Photos 3 and 4 of Attachment C. Traveling from north to south along the west side of SR AlA, the conceptual plan proposes an unsignalized crosswalk traversing Ramp A. The plan calls for the installation of appropriate curb ramps and pavement markings at this location. Given the crossings' location within Ramp A's horizontal curve, it is recommended that a yield treatment similar to Scheme II of FDOT Index 17346 be implemented at this location. Note that it is recommended that the distance from the yield line to the crosswalk be reduced from the FDOT standard of 40 feet to the MUTCD minimum standard of 20 feet in order to install the yield line within the ramp rather than the southbound through lanes of SR AlA. A six-foot sidewalk is proposed adjacent to southbound Collins Avenue/SR AlA from Ramp A to Ramp B. Construction of this sidewalk and associated curb ramps will require the removal of existing landscaping material (Photo 5 - Attachment B). Coordination with the City of Sunny Isles Beach will be necessary to address this removal of landscape material as part of future design efforts. A signalized pedestrian crosswalk along with the appropriate curb ramps are proposed at Ramp B. The pedestrian phase would operate during the concurrent north-south vehicular phase on Collins A venue. This phase operates on recall mode; therefore, pedestrian pushbuttons would not be required. Along the northwest side of Ramp C, a six-foot sidewalk is proposed. The construction of this sidewalk will require the removal of both landscape and hardscape material. A marked crosswalk is proposed at the one-way stop controlled intersection of the Ramp C and the Business Loop. The installation of this crosswalk will require pavement marking and signage modifications. A six-foot sidewalk is proposed along the east side of the Business Loop from the Ramp C to eastbound NE l63rd Street. Consistent with other areas of sidewalk construction, existing landscape and hardscape material will require removal (Photo 9 - Attachment C). Existing utility guy wires may need to be relocated in order to
