Cocoplum Terrace Traffic Study
REQUEST
A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY OF SOUTH MIAMI,FLORIDA.
RELATING TO ACCEPTING THE RESULTS AND THE RECOMMENDATIONS OF THE TRAFFIC STUDY
CONDUCTED BY MARLIN ENGINEERING INC..FOR COCOPLUM TERRACE AREA.
BACKGROUND;
In the recent months there have been numerous complaints about traffic intrusion,speeding,
volume of traffic in various neighborhoods.One of the neighborhoods that is impacted is the
area bounded by Sunset Drive in the south,62nd Avenue in the east,64l Street in the north and
Brewer Canal on the west.Marlin Engineering Inc.was retained by the City to conduct a traffic
study and develop a mitigation plan for the area.Based on the traffic analysis and resident input
through public workshops,the consultant developed the attached mitigation plan and a
preliminary cost estimate for implementation of their recommendations.The mitigation plan
was presented to the community and was well received.
The next step is to submit these recommendations to the Miami Dade County Fire and Public
Works Departments and the Florida Department of Transportation for their respective approvals.
Following their approvals an inter-local agreement between the Miami Dade County and the City
would have to be executed for the City to implement these recommendations and accept the all
associated liabilities.Concurrently,the City Commission would have to approve the funding for
the project.
RECOMMENDATION
It is recommended that the City Commission accept the study and its recommendations and
direct the staff to work with the County and the State to get the necessary approvals for
implementation of those recommendations.

Executive Summary
The City of South Miami is considering the implementation of neighborhood traffic
management for the residential area bounded by Brewer Canal from the west,Sunset
Drive from the south,SW 62nd Avenue from the East,and SW 64th Street from the north.
The purpose of the study is to address speeding and traffic intrusion in local residential
streets.The City initiated a traffic management study by contracting engineering services
from Marlin Engineering,Inc.(MEI)to perform traffic data collection and analysis,as
well as development of traffic calming alternatives for the study area.
To identify the magnitude of the problems within the study area,traffic data were
collected during the month of May 2001,which included 24-hour vehicle volume counts
at 8 locations,24-hour vehicle speed studies at 4 locations,24-hour vehicle classification
counts at 3 locations,and 5-hour turning movement counts at the three signalized
intersections along SW 62nd Avenue.Also,two public workshops were held with the
residents of the study area to initiate and maintain a close dialogue with the community,
receive information on public traffic concerns at specific locations and explore potential
useof adequate traffic calming devices.
As a study result of the traffic management analysis,summary recommendations on
improvements and cost estimate follow:
-Install a second left-turn lane and directional signs to US-1 northbound for eastbound
approach on Sunset Drive and re-stripe the eastbound lanes before and after SW 62
Avenue intersection.Install US-1 Northbound Guide Sisms on Sunset Drive.
-Install partial-closure for westbound traffic on SW 70th Street west of SW 62
Avenue (west of the Social Security and the Medical Offices).^
-Install traffic circles at the following intersections:SW 63r Avenue/SW 70 Street,
SW 62nd Court/SW 69th Street,SW 64th Avenue/SW 68 Street,SW 63
Avenue/SW 68th Street,SW 64th Avenue/SW 66th Street,and SW 63r Avenue/SW
-Installed tables north of Sunset Drive on SW 64th Ct.,SW 63rd Ct and SW 63rd
Ave.and south ofSW 64th St.on SW 64th Ct.,SW 63rd Ct.and SW 62"Ct.
.install .peed table/street narrowing west of SW 62nd Avenue,on SW 69 Street and
SW 68th Street,to create a transition for traffic operation between commercial and
residential areas along SW 62nd Avenue.
