Re: Brickell Key Traffic Evaluation - #14221
Dear Chris,
The purpose of this letter is to document the proposed pm peak hour vehicular traffic exiting
Brickell Key on a typical weekday for a new development program. Further, this letter will
compare the vehicular trips from the proposed development program to the rnaxinnun non-
residential development allowed in the development order. The proposed development program
includes the following;
• 650 DUs of residential condominium
• 100,000 sf of office
• 50,000 sf of retail
• 25,000 sf of restaurant
A development order (DO) with the South Florida Regional Planning Council and the city of
Miami limits the exiting traffic volume from Brickell Key during the weekday prn peak hour at
800 vehicular trips. The DO also limits the non-residential uses to 1,200,000 sf, of which
150,000 sf can be retail. The inbound and outbound traffic counts were taken at the Brickell Key
Bridge on Tuesday, September 16, 2014 and on Wednesday, September 17, 2014 (see Appendix
A for traffic counts).

A summary of the traffic count data during the pm peak hour for the vehicular trips exiting
Brickell Key is shown in Exhibit 1.

Based on the traffic counts, the current exiting traffic volume from Brickell Key during the
weekday pm peak hour does not exceed the 800 vehicular trips threshold. There are 234 exiting
weekday pm peak hour vehicular trips left before reaching the threshold.
Currently, Brickell Key has the following land uses and intensities on site:
a 3,093 DUs of residential condominium)
• 324,620 sf of office
• 20,979 sf of retail
• 3,303 sfofrestaurant
The city of ivliami converts the 329 room hotel to 164 DUs of residential condominium
The Institute of Transportation Engineers (ITE) recognizes that data obtained to establish trip
generation rates and/or equations is collected at single -use, free-standing sites, and that mixed -
use developments, like Brickell Key, provide a potential for interaction of trips within the site,
which must be accounted for separately, ITEs Trip Generation Handbook provides guidelines
for establishing theoretical internal capture for mixed -use developments,
Brickell Key is a unique mixed -use development as there is only one access point to the
mainland via the Brickell Key Bridge. Therefore, actual internal capture rates can be calculated
using .ITEs trip generation rates/equations and existing traffic count data. These calculations
were undertaken and are shown on Exhibit 1 Sec Appendix B for trip generation worksheets,

By adding vehicular trips from the proposed additional development to Brickell Key, the future
with project exiting traffic volume during the weekday pm peak hour is not expected to exceed
the 800 vehicular trips threshold. This analysis shows there will be 26 exiting pm peak hour
vehicular trips left under the threshold (800 - 774 = 26) with the proposed additional
development,
Exhibit 2 also shows the proposed development program generates 27,271 gross daily vehicular
trips (per ITEs Trip Generation Handbook) while the maximum allowed non-residential uses
(1,2M sf) program generates 33,175 gross daily vehicular trips. The proposed plan generates
approximately 1.8% less gross daily vehicular trips compared to the maximum allowable non-
residential uses program.
