COMMISSION ITEM SUMMARY
Condensed Title:
A Resolution to Adopt the City Traffic Cal ing Manual and to execute an Interlocal Agency Agreement with Miami -Dade
County.
Key Intended Outcome Supported:
Enhance mobility throughout the City.
Supporting Data (Surveys, Environmen al Scan, etc.):
Transportation remains one of the most -ignificant areas to address from the 2009 Community Satisfaction Survey
results (often mentioned as a Key Quality .f Life Issue). 24% of residents rated traffic flow as excellent or good, and 37%
as poor. 35% of residents rated the avail.: bility of pedestrian trails and bicycle paths /lanes as excellent or good, and
30% as poor.
Issue:
Should the City Commission approve the - solution to adopt the City Traffic Calming Manual and to execute Interlocal
Agency Agreement with Miami -Dade Cou ty?
Item Summary /Recommendation:
The Administration has been working with he County for over a year on the approval of the City Traffic Calming Manual
(TCM) and the associated Intergovernme tal Agency Agreement (IAA). On July 22, 2010, the County's Public Works
Director submitted a letter to the City gr -nting authority to the City to follow the guidelines of the City's TCM when
performing traffic studies. In the meanti e, the City has been working to finalize the IAA that will grant the City its
respective limited authority, pursuant to S-ction 2 -96.1 of the Miami -Dade County Code
The TCM and the IAA were both present to the Finance and Citywide Projects Committee on April 27, 2011. The
members of the Committee recommende• approval of both the TCM and IAA.
The County's granting of authority to the City to employ the City's TCM does not relinquish the County's standing
jurisdiction over all traffic engineering cou tywide. The current agreement states that the City may measure, analyze and
develop traffic calming measures, while he County will be the final authority in their approval. The City would be
responsible for incurring all costs associa ed with the implementation of traffic calming devices.
The currently agreed process with the Co nty establishes that the City would take requests from the residents for traffic
calming measures. The City would then c. nduct an engineering analysis to determine if the installation of traffic calming
devices is warranted. If warranted, the Ci would develop engineering plans and seek approval from the Miami Beach
Fire and Police Departments The City wo Id then have to obtain County approval of the plans prior to the installation of
any traffic calming devices. The County would assure that the review process would be expedited to the City within ten
(10) working days after submittal. The Co nty reserves the right to deny approval of any Traffic Calming Package.
THE ADMINISTRATION RECOMMEND • APPROVAL OF THE RESOLUTION TO ADOPT THE CITY TRAFFIC
CALMING MANUAL AND TO EXECUTE INTERLOCAL AGENCY AGREEMENT WITH MIAMI -DADE COUNTY.

SUBJECT: A RESOLUTION OF THE MAYO" D CITY COMMISSION OF THE CITY OF
MIAMI BEACH, FLORIDA, ADOPTING THE CITY OF MIAMI BEACH TRAFFIC
CALMING MANUAL(TCM); FURTHER APPROVING AND AUTHORIZING THE
CITY MANAGER TC EXECUTE AN INTERGOVERNMENTAL AGENCY

ADMINISTRATION RECOMMENDATION
The Administration recommends approving the resolution to adopt the City Traffic Calming
Manual and to execute an Interlocal Agency Agreement with Miami -Dade County.
EXECUTIVE SUMMARY
The Administration has been working with the County for over a year on the approval of the City
Traffic Calming Manual (TCM) and the associated Intergovernmental Agency Agreement (IAA)
(Attachments A & B, respectively). On July 22, 2010, the County's Public Works Director
submitted a letter to the City gra sting authority to the City to follow the guidelines of the City's
TCM when performing traffic stadies (Attachment C). In the meantime, the City has been
working to finalize the IAA that w II grant the City its respective authority, pursuant to Section 2-
96.1 of the Miami -Dade County Code.
The TCM and the IAA were both presented to the Finance and Citywide Projects Committee on
April 27, 2011. The Committee recommended approval of the TCM and the IAA.
The County's granting of authority to the City to employ the City's TCM does not relinquish the
County's standing jurisdiction over all traffic engineering countywide. The current agreement
spells out that even though the City would be granted the authority to measure, analyze, and
develop traffic calming measures the County would still be the final authority in the approval of
any traffic calming measures proposed by the City. The City would be responsible for incurring
all costs associated with the implementation of traffic calming devices.
The currently agreed process with the County establishes that the City would take requests from
the residents for traffic calming measures, the City would then conduct an engineering analysis
to determine if the installation of traffic calming devices is warranted or not, the City would then
develop the respective engineer ng plans, and subsequently seek approval from the Miami
Beach Fire and Police Departments. The City would then have to obtain County review and
approval of the plans prior to the installation of any traffic calming devices. The County, on the
other hand, would assure that the review process would be expedited to the City within ten (10)
working days after submittal.

BACKGROUND
The City has established criteria that determine the need for traffic calming that is consistent
and compatible with the guidelines established by the County for traffic calming. However, the
City only uses three (3) basic parameters to determine if traffic calming is warranted: speed,
volume, and number of accidents per year during the last three years. The County employs
additional criteria. A comparative - eview (County vs. City) is provided in a table (Attachment D),
which illustrates that traffic calming is triggered at lower thresholds when using the City's
methodology as opposed to the County's.
An example of the differences )etween the City and County criteria is the traffic calming
analysis for 51 Street between Alton Road and Pine Tree Drive. The County had initially
denied the request for the installation of traffic calming devices along this street based on its
criteria. By applying the criteria established within the City TCM, City staff determined that the
street met the requirements for the installation of speed cushions. Once the City TCM and IAA
are approved, the engineering drawings together with the analysis will be submitted to the
County for review and approval.
The City attempted to get the County to agree that complete traffic calming packages submitted
to the County will not be denied. Instead, the County would provide review comments and return
the package to the City for rework. The County did not agree to incorporate this condition into
the IAA. Therefore, the County still reserves the right to deny approval of any traffic calming
packages.
ANALYSIS
Once the City TCM becomes formally adopted by the County via the IAA, the City will then be
able to follow its own process to cetermine if traffic calming devices are warranted. Through this
formal approval, the County would allow the City to follow its procedures, which are more
concordant with the daily operation and configuration of the City's street system, through an
evaluation process that places a specific value to traffic volumes, and speeds that exceed the
posted speed limit. City staff will continue to work with the County on refinements to the TCM as
it is implemented. As an example, some of the issues currently being contemplated for
refinements are acceptable types of traffic calming devices for various City street classifications.
The Administration provided Lpdates on the City's Traffic Calming Program to the
Neighborhoods and Community Affairs Committee (NCAC) on May 25, 2010 and on August 31,
2010. At its August 31, 2010 meeting, the members of the NCAC moved to recommend
approval of the TCM and referred it to the Finance and Citywide Projects Committee for a
review of its financial impacts. Or April 27, 2011, the Finance and Citywide Projects Committee
recommended approval of the TCM and IAA.
By adopting the City's TCM and entering into an IAA, the City will be responsible for all
planning, engineering, installation and maintenance of traffic calming measures along with their
associated financial impacts. The costs associated to the implementation of traffic calming
Citywide will need to be gauged on a yearly basis and programmed into the City's yearly Capital
Budget. An example of the approximate cost for the installation of speed cushions is provided in
the breakdown below. The followi ig example delineates the breakdown of the approximate cost
for the installation of speed cushions at nine (9) locations on Sunset Islands 3 and 4:
Commission Memorandum — Traffic Calming Manual And The Intergovernmental Agency Agreement
June 1, 2011
Page 3 of 4
Planning and Engineering $ 6,000
Speed Cushions $14,000
Signs $ 1,400
Construction (JOC Contractor) $18,000
Total Cost $39,400 or about $4,380 per speed cushion location
The City also retained the services of The Corradino Group to conduct an evaluation of the
potential costs of implementing the TCM. The analysis identified potential locations for traffic
calming and estimated an average cost for the application of traffic calming at the identified
locations.
An examination of the federal functional classification map identified certain local streets that
may be eligible for and potentially require traffic calming, since federally classified arterial
roadways are not eligible for traffic calming pursuant to the TCM and the City's arrangement
with the County. The processes and procedures for traffic calming provided in the TCM, which
include factors such as assumed traffic speeds and volumes, were also taken into
consideration. However, the identified locations are concept in nature and would require formal
evaluation to determine if traffic calming is warranted.
The conceptual locations were assigned the average cost per typical traffic calming device and
the potential total cost of implementing the TCM was estimated to be $2,347,794. However,
since all locations must be warranted based on the processes and procedures in the TCM, a
more conservative cost estimate was developed by assuming that forty percent (40 %) of the
conceptual locations would actually warrant traffic calming. It was further assumed that out of
the forty percent (40 %) of conceptual locations, thirty percent (30 %) of the locations would
receive speed cushions and te-i (10 %) would receive more complex treatments. Although a
variety of traffic calming techniques and treatments could be implemented, it is anticipated that
the majority of the warranted locations would receive speed cushions. More complex
treatments, such as traffic circles and medians, may also be used, but with less frequency due
to their cost, size, and right -of -way requirements.
The average cost of speed cushions, including design, engineering, construction, and
contingency, is estimated to be $5,000 per speed cushion. The average cost of more complex
treatments, such as traffic circles, bulb -outs, diverters and medians, is estimated to be $30,000
per treatment. (At this time, the County is not approving concrete speed bumps.) This resulted
in a conservative estimated cost of $950,000 for the implementation of the TCM. The TCM
stipulates that in order for the C ty to implement traffic calming, the affected area must agree to
pay for one half of the device(s) purchase costs. Based on this requirement, the final cost to the
City is estimated to be $475,000.
A list of traffic calming requests will be reviewed yearly as part of the capital budget process and
will compete with other Peoples Transportation Plan and Concurrency Mitigation funded
improvements. It is anticipatec that the City will commit approximately $50,000 per year for
traffic calming.
CONCLUSION
The Administration recommencs approving the resolution to adopt the City Traffic Calming
Manual and to execute an Interlocal Agency Agreement with Miami -Dade County.
