Major Use Special Permit Traffic Impact Study
Transportation Study Methodology
Introduction
A Major Use Special Permit (MUSP) Traffic Impact Study is being prepared to support the proposed
redevelopment plans for the new Marlins Ballpark to be located on the site of the former Orange Bowl
Stadium, 'bounded by NW 16 Avenue on the west, NW 7 Street on the north, NW 14 Avenue on the east
and NW 3 Street on the south, in the City of Miami, Miami -Bade County, Florida.
MUSP Trak Impact Study
The information outlined in this Transportation Study Methodology identifies the transportation information
needed to address the MUSP traffic impact study requirements of the City of Miami in order to process a MUSP
Application for the new Marlins Ballpark to be located on the site of the former Orange Bowl. The MUSP Traffic
Impact Study will initially assume that up to 6,000 structured parking spaces will be located to the immediate
north and south of the ballpark, and that up to 50,000 square feet of ancillary ground level specialty retail and up
to 54 apartment dwelling units will be integrated into the parking structure as liner uses. The Applicant will
coordinate with the City to incorporate plan changes to the number of structured and at -grade parking spaces
provided, the square footage of the retail use and the number of dwelling units as liners to the parking structures
in an attempt to make the MUSP Traffic Impact Study as accurate as possible. It is anticipated that program
changes may still occur following review by City Staff during the MUSP review process.
As part of the MUSP Traffic Impact Study, the Applicant is incorporating comments received from the Miami -
Dade County Public Works Department dated March 19, 2008. The MUSP Traffic Impact Study will evaluate
inbound and outbound vehicular, pedestrian and transit circulation to and from the Ballpark site. This
methodology will document the data collection locations and traffic study approach used to evaluate traffic
impacts consistent with adopted level of service standards from the Miami Comprehensive Neighborhood Plan
(MCNP). The MUSE' Traffic Impact Study shall include the information listed below.
Traffic Data
• Turning movement traffic counts will be collected at study area intersections from 5:30 PM to 7.30 PM
to reflect the portion of the evening peak hour that would coincide with the potential start time of a
weekday evening baseball game. Traffic counts will be collected at the intersections listed in Table 1
below.
• Turning movement traffic counts will be collected at study area intersections from 9:30 PM to 10:30 PM
to reflect the post game peak hour that would coincide with the potential end time of a weekday evening
baseball game. Traffic counts will be collected at the intersections listed in Table 1 below.
• Year 2007 traffic counts from State and County Count Stations will be assembled from FDOT and
Miami -Dade County Public Works to evaluate traffic conditions for the surrounding study area roadway
network.

Traffic Counts
Pursuant to the June 4, 2003 scoping meeting with Miami -Dade County and the City of Miami, and based
upon data collection and analysis that is most important in addressing inbound and outbound circulation to and
from the Stadium Site, intersection turning movement traffic counts will be collected at the study area
intersections listed in Table 1 below from 5:30 PM to 7:30 PM to reflect the evening peak hour that would
coincide with the potential start time of a weekday evening baseball game, and where noted, from 9:30 PM
to 10:30 PM to reflect the post game peak hour that would coincide with the potential end time of a weekday
evening baseball game. The location of these traffic counts are illustrated on attached Figure 1.

Trip Distribution
• The directional trip distribution and assignment of inbound and outbound project trips will be developed
using the Miami-Dade Transportation Plan (to the Year 23301) - Directional trip Distribution Report
(dated January 2005). The distribution and assignment for the project TAZ 757 will be based upon the
Mlami-Dade Interim Year 2015 Cost Feasible Plan, and wilt address the direction of project trips to and
from the project site.
Trip Generation
• The vehicular and person trip generation for the project site will be developed using information
provided by the Florida Martins based upon the number of stadium seats, parking availability and
persons per vehicle for a baseball game.
• The modal split and potential transit ridership will be developed using information from the 2007 HNTB
study, combined with ridership data from Miami-Dade Transit for other South Florida sporting events.
• The information from both the 2007 NNTB study and the prior 2005 PB study will be considered and
evaluated for use, however the assumptions for both vehicular trip generation, site arrival time
distribution and site departure time distribution will be adjusted as needed to reflect realistic travel
patterns and behavioral characteristics for a weekday evening baseball game.
• The vehicular and person trip generation for the commercial and residential uses which will be included
as liners to the parking structures will be calculated using rates and equations from ITE Trip
Generation, 7h Edition.
Driveways and Access
■ The study shall include the identification of project driveways serving as vehicular access to parking,
vehicular access to the commercial and residential uses included in the liners to the parking structures,
stadium operations, or transit access for patron drop-off or pick-up.
• The study will include the estimated assignment of project traffic entering and departing each project
driveway for the peak hour coinciding with the arrival to a weekday evening baseball game.
■ The study will include the estimated assignment of project traffic entering and departing at each project
driveway for the peak hour coinciding with the departure from a weekday evening baseball game.

Improvement Plan.
• The study will identify the planned transportation improvements from Priority I and II of the MPO 2034
Long Range Transportation Plan which are planned for implementation by the Year 2015.
• The study will include an analysis of the regional and local roadway network providing access to the
site, documenting existing traffic conditions, future background plus committed development traffic
conditions and total traffic conditions [consistent with the MCNa incorporating the impacts of the
Marlins Stadium during the following timeframes:
• The peak hour coinciding with the start of a weekday evening baseball game (6:00 to 7:00 pm);
• The peak hour coinciding with the end of a weekday evening baseball game (9:30 to 10:30 pm),
Study Area Intersection Operations
• The study will examine the operations of selected study area intersections under total traffic conditions
for the following timeframes:
• The peak hour coinciding with the start of a weekday evening baseball game (6:00 to 7:00 pm);
• The peak hour coinciding with the end of a weekday evening baseball game (9:30 to 14:30 pm).
• Intersection turning movements will be documented graphically and in spreadsheet format for existing
conditions, future background plus committed development traffic and total traffic conditions
incorporating the impacts of the Marlins Ballpark during the following timeframes:
• The peak hour coinciding with the start of a weekday evening baseball game (6:40 to 7:00 pm);
• The peak hour coinciding with the end of a weekday evening baseball game. (9:30 to 10:34 pm).
• Based upon the results of the intersection analyses for the pre -game (arrival) scenario and the post-
