A Resolution Of The Mayor And City Commission Of The City Of Miami Beach, Florida, Rejecting The Recommendation By
Staff And Respective Consultants Atkins North America, Inc. And Street Plans, Inc. Following A Presentation To The
Finance And Citywide Projects Committee On March 21, 2013 And Directing Staff To Continue To Evaluate The Reduction
Of Prairie Avenue To Eliminate The Current Bicycle Lanes And Study Further The Possibility Of Including An Advisory
Bicycle Lane Along Both Prairie Avenue And Royal Palm Avenue; And Further Authorizing The City Manager To De-
Program Work Associated In The Construction OfThe Valley Gutters And Re-Grading And Milling And Resurfacing Along
Prairie Avenue, As Authorized Under Resolution 2013-28163; Modifying Such Amendment To Add To The Contract Funds
For A One Inch Overlay Of Asphalt Over The Current Existing Roadway And Resurface The StreetTo A Drivable Condition
Durina The Experiment And Approval Process For An Advisory Bicycle Lane.
Intended Outcome Su orted:
reValue and Timely Delivery of Quality Capital Projects, Improve Storm Drainage Citywide, and Maintain City's
ture
Supporting Data (Surveys, Environmental Scan, etc.):
The 2012 Customer Satisfaction Survey indicated that over 81% of residents rated recently completed capital
improvement projects as "excellent" or "good". Recently completed capital improvement projects (81%), storm
draina e 37% , and condition of roads 44% .
Item Summary/Recommendation:
On March 13, 2013 the City Commission adopted resolution 2013-28163, which approved the construction contract
Amendment No. 2 in the amount of $3,723,986 to implement the proposed design change pursuant to the adopted BOOR
Amendment of July 181h, 2012.
During the Commission meeting, concerns were voiced by residents requesting further that the adopted Contract
Amendment include the reduction of Prairie Avenue via the elimination of the current bike lanes, while at the same time
evaluating the feasibility of including a Bicycle facility along the BOOR amended roadway width of Royal Palm Avenue. The
Commission granted the authority to the City Manager to proceed with Amendment No. 2 as presented, contingent that
staff evaluates further the possibility of incorporating these requests without affecting the timelines and cost to the current
Bayshore A contract. A request was made also to further refer this matter to the March 21, 2013 Finance and Citywide
Projects Committee (FCWCP).
The City retained the services of Atkins North America and Street Plans Inc., experts in the motor vehicle and bicycle traffic
fields, in order to determine the feasibility of removing the existing bicycle lane along Prairie Avenue and instead provide a
bicycle boulevard along Royal Palm Avenue. In its preliminary review of the current conditions and based on data
previously obtained, the team determined that it is not feasible to remove a bicycle facility on Prairie Avenue and replace it
with another bicycle facility on Royal Palm Avenue, as the lanes provide for connectivity advantages within neighborhoods
and to adjacent collectors.
The Consultant team identified two alternatives, the possibility of including an advisory bicycle lane along both Prairie
avenue and Royal Palm avenue or to explore the concept of a new bicycle boulevard on Royal Palm Avenue.
Should the Commission choose to continue to explore the alternatives, City staff would have no option but to de-program
certain portions of the construction of Prairie Avenue from the currently approved construction documents.

During the Commission meeting, concerns were voiced by residents requesting further that the
adopted Contract Amendment include the reduction of Prairie Avenue to twenty (20) feet plus 2
foot valley gutters (24 feet total) via the elimination of the current bike lanes, while at the same
time evaluate the feasibility of including a Bicycle facility along the BOOR amended roadway
width of Royal Palm Avenue. The Commission granted the authority to the City Manager to
proceed with Amendment No. 2 as presented, contingent that staff evaluates further the
possibility of incorporating these requests without affecting the timelines and cost to the current
Bayshore A contract. A request was made also to further refer this matter to the March 21, 2013
Finance and Citywide Projects Committee (FCWCP) (See Exhibit A-Memorandum to FCWCP
-Central Bayshore Bid Package 8A-Bicycle Lanes I Bicycle Boulevard on Prairie Avenue and
Royal Palm Avenue)
In preparation for the FCWCP, the City retained the services of Atkins North America and Street
Plans Inc., experts in the motor vehicle and bicycle traffic fields, in order to determine the
feasibility of removing the existing bicycle lane along Prairie Avenue and instead provide a
bicycle boulevard along Royal Palm Avenue. In its preliminary review of the current conditions
and based on data previously obtained, the team determined that it is not feasible to remove a
bicycle facility on Prairie Avenue and replace it with another bicycle facility on Royal Palm
Avenue, as the lanes provide for connectivity advantages within neighborhoods and to adjacent
collectors, including the possibility of connecting a bike path within the swale area adjacent to
Miami Beach High to the 8 foot multi-purpose path circulating the Par 3 Golf Course
(potentially funded by safe routes to schools grants). Refer to Exhibit C-Par 3 Golf Course
Plan. The Team did however emphasize the benefit of providing an additional bicycle facility
along Royal Palm Avenue to support connectivity and as an enhancement to the overall bicycle
network.
As part of this review, the City also consulted with the Miami-Dade Public Works and Waste
Management (PWWM) Traffic Engineering Division (TED), to obtain their input on this added
request by the residents. As the agency responsible for traffic control countywide, the Miami
Dade TED staff has opined that the removal of the bicycle lane along Prairie would not be
considered because bicyclists have a legal right to travel on all streets in the State of Florida
except where specifically prohibited, e.g. Interstate Highways and other limited access facilities.
The conversion of one street (Royal Palm) into a more bicycle-friendly facility is not a
justification to reduce safety for bicyclists on another street (Prairie). It is the TED's position that
apart from being a violation to Federal, State and County regulations, the bicyclists would
continue to use Prairie Avenue, due to its connectivity advantages, and without the proper
protection granted by a separate assigned bike lane. The TED further indicated that in order to
remove bike lanes, the City would need to be compliant with Federal and State requirements,
would need subsequent approval by adjacent residents, and would need to prove that the
existing bike lanes are ineffective and unsafe. It is important to underline that the TED's position
has been identified in memos to the City Commission with respect to the same subject and
concerns.
Advisory Bicycle Lanes
In an effort to accommodate the desire to narrow Prairie Avenue and still provide a bicycle
facility, the consultant team proposed an experimental Feature named an Advisory Lane. Under
FHWA criteria, an experimental feature is a material, process, method, equipment item, traffic
operational device, or other feature that: (1) has not been sufficiently tested under actual service
conditions to merit acceptance without reservation in normal highway construction, or (2) has
been accepted but needs to be compared with alternative acceptable features for determining
their relative merits and cost effectiveness. Advisory bicycle lanes, an experimental feature,
525
Central Bayshore A -Bicycle Lanes Memorandum
April 17,2013
Page 3 of 5
share some similarities with conventional bicycle lanes, but they are typically only on roads with
low volumes and low speed. (On Prairie Avenue, the volume is about 2,200 vehicles per day,
and the average speed for this corridor decreased from 36.3 miles per hour to 25 miles per hour
following the installation of traffic calming devices in January 2009.) Advisory bicycle lanes force
vehicles to share a center unmarked space that is less than the standard width for two (2) travel
lanes. Vehicles merge into the bicycle lane upon meeting oncoming traffic. Motor vehicles must
operate cautiously and yield to any bike traveling on the bicycle lane at the merge point. (Refer
to Exhibit B for the consultant's presentation including Illustrations of advisory bike lanes.)
Unlike traditional bike lanes, the inside marking for advisory bike lanes is a dashed white line.
This dashed marking gives bicyclists a dedicated space to ride but makes the space available to
motorists to pass oncoming traffic. On roads with advisory bike lanes, the center marking is
removed. (According to the 2009 Manual on Uniform Traffic Control Devices (MUTCD), a yellow
center marking is not required on roads with less than 6,000 vehicles per day.)
Although the concept of advisory bike lanes fits the existing traffic operations for the Prairie
Avenue corridor, it remains an experimental process and it is untested and a significant federal
and county approval process must be followed. Further, the Miami Beach Fire Department and
Miami Beach Police Department would also need to approve the design, since these
modifications could impact response times.
Advisory bicycle lanes are currently being tested under a pilot project on East 14th Street in the
Elliot Park Neighborhood in Minneapolis, Minnesota. This Administration (FHWA) facility
performance test is for a period of three (3) years. As the project is still in the test phase, the
City would need to obtain a similar FHWA approval. A similar process such as this would not fit
within the current timelines of the Central Bayshore Project.
In addition, the City would have to obtain approval from Miami Dade County for this facility type
on Prairie Avenue. In preliminary conversations, TED staff has not been receptive to the
concept of replacing the existing bike lanes with advisory bike lanes. Staff has expressed that
the advisory bike lanes may decrease the safety of the corridor for bicyclists and increase
conflict points between motor vehicles. The County has indicated that the City would have to
study the area and prove that this practice will be qualitatively similar to the existing conditions
for both motor vehicles and bicycles.
Bicycle Boulevard
The City also approached the TED with the concept of a bicycle boulevard on Royal Palm
Avenue; the TED stated that bicycle boulevards are not part of their adopted bicycle facility
standards or the currently adopted Manual of Uniform Traffic Control Devices (MUTCD). Such a
proposal would warrant an individual traffic flow analysis for which the County would have to
further evaluate on its feasibility and technical functionality. The County would also require a
traffic flow modification application which would warrant two thirds approval by residents or
majority approval by the Miami Beach City Commission.
In summary, the process for implementing the above revisions to the plans would be as follows:
• A traffic flow analysis of the entire Central Bayshore neighborhood must be conducted.
• Once the traffic study is conducted, and if warranted, a revised design for all
intersections, including drainage, must commence.
• Once the traffic flow analysis is conducted, and if warranted, approval by 2/3 vote from
all residents within the Central Bayshore Neighborhood or majority approval by the City
Commission must be obtained.
526
Central Bayshore A -Bicycle Lanes Memorandum
April 17,2013
Page 4 of 5
• If intersections are significantly affected by the new design, a 100% vote approval from
residents at all intersections along Royal Palm Avenue between 28th Street and 40th
Street or City Commission approval must be obtained.
• Additional fees would need to be approved to the engineer of record, via Commission, to
do the study and design.
• Approvals from City of Miami Beach Fire Department and Police Department.
• Permits from Miami-Dade County and CMB Public Works Department must be issued.
• Additional construction cost for the project would require Commission approval.
Timelines
It would be anticipated that the process for approval of the Bicycle Boulevard could take
anywhere from 7 -1 0 months. It would also be anticipated that the process to introduce a new
• concept such as an Advisory Bicycle Lane on either Prairie Avenue and/or Royal Palm Avenue,
would not take place within the current construction time frame.
CONCLUSION
As stated above, because the timelines to obtain approvals for the alternative bicycle facilities
are not feasible within the current construction timelines for Central Bayshore, should the
Commission choose to continue to explore the alternatives, City staff would have no option but
to de-program certain portions of the construction of Prairie Avenue from the currently approved
construction documents, such as the construction of valley gutters and the milling and
resurfacing of the roadway. Although the underground drainage system would remain as part of
the project, the catch basin elevations would need to be reassessed and perhaps redesigned to
be re-adjusted in the event the roadway would end up being narrowed and flumes would need
to be constructed to achieve proper shallow concentrated flow into the drainage system. During
this interim condition the bicycle connection to the respective facilities would also remain,
including the connectivity to the current bike lanes along Prairie; however connectivity from the
multipurpose parking facility within Par 3 to Royal Palm Avenue would need to be created once
the alignment for such facility is properly defined. See Exhibit C.
RECOMMENDATION
My recommendation is to maintain the current width of Prairie Avenue as well as its respective
bicycle lanes pursuant to the regulations established by Miami Dade County Public Works
further retaining Royal Palm Avenue's current design as proposed in the construction plans and
as approved under Resolution 2013-28163 via Amendment No. 2 to Lanzo Construction Co.
This recommendation is consistent with the views expressed by my staff and our consultant
Atkins North America. Pursuing the alternatives will significantly delay the project, increase the
costs, and may not result in any improvement if the experiment fails.
Should the City Commission direct staff to continue to explore the possibility of an alternative
bicycle facility on Prairie Avenue such as an Advisory Bicycle Lane, we would have no option
but to carve out portions of the currently approved and funded scope of work. This would entail
not conducting the work associated in the construction of the valley gutters as well as proposed
re-grading and milling and resurfacing of the street. Instead, the City would provide for a
temporary condition during the experiment and approval process by resurfacing the street to a
drivable condition by providing a one inch (1") overlay of asphalt over the current existing
roadway. Installation of drainage would remain as part of the current contract, as the drainage
permit requires the road to be designed to the currently approved level of service. The
respective credits and charges associated to these modifications would have to be negotiated

SUBJECT Central Bayshore Bid Package SA
Bicycle Lanes I Bicycle Boulevard on Prairie Avenue and Royal Palm Avenue
Background I Amendment to BOOR:
In early 2010, following completion of design and permitting services for the Central Bayshore
project area, the neighborhood association (HOA) requested that the City consider modifying
the width of some streets in the project area as well as enhancing the landscaping presented as
part of the original design.
On August 25, 2011 ,members of the Bayshore HOA met with CIP to request that eleven (11)
items be considered for incorporation into the project. The requested changes required are
amendments to the previous BOOR, upon which the project design was developed, or were
modifications to the BOOR
On July 9, 2012, the Administration presented the aforementioned revisions to the Finance and
Citywide Projects Committee (FCWPC) regarding additional capital budget requests to include
additional infrastructure needs for stormwater, roadway milling, resurfacing, and valley gutter
improvements.
On July 18, 2012, the Mayor and City Commission approved the amendment to the BODR as
approved by the FCWPC.
HOA Request -Prairie Avenue I Royal Palm Avenue
In October 2012 members of the Central Bayshore HOA continued to request that City staff
consider the removal of bicycle lanes on Prairie Avenue and the implementation of a "Bicycle
Boulevard" on Royal Palm Avenue. A meeting took place on December 13, 2013 between City
staff and members of the Central Bayshore HOA to discuss the possibility of re-introducing the
narrowing of Prairie Avenue by removal of the bicycle lanes.
That request had previously been presented as part of the 11 HOA requests at the July 9, 2012
FCWPC meeting, however FCWPC did not recommend the change and, therefore, it was not
included in the BOOR design change adopted by Commission. The City subsequently executed
a contract amendment with the engineer of record, CH2M Hill, on July 18, 2012 for the BOOR
design changes excluding this request.
On March 13, 2013, the Commission approved the construction contract Amendment in the
amount of $3,723,986 as a result of the design change. but directed that the HOA request for
the bicycle lanes be reviewed by FCWPC.

Royal Palm Avenue Bicycle Boulevard
The definition of a bicycle boulevard as per "Fundamentals of Bicycle Boulevard Planning &
Design Guidebook, V1.1, July 2009", is a "low-volume and low-speed street that has been
optimized for bicycle travel through treatments such as traffic calming and traffic reduction,
signage and pavement markings, and intersections crossing treatment.· The common theme of
these facilities is of reducing the volume and speed of motor vehicle traffic (particularly non-
local, cut-through traffic), and creating a comfortable space where bicyclists, and often
pedestrians as well, have priority along the street". The primary characteristics of a Bicycle
Boulevard are as follows:
• Low motor vehicle volumes
• Low motor vehicle speeds
• Logical, direct, and continuous routes that are well marked and signed
• Provide convenient access to desired destinations
• Minimal bicyclist delay
• Comfortable and safe crossings for cyclist at intersections
Currently there are no Bicycle Boulevards within the City of Miami Beach. In order to create a
bicycle facility such as this on Royal Palm Avenue under the current City Commission approved
20 feet, a design must be considered where traffic is diverted from Royal Palm from 28 1h Street
to 40tt1 Street and onto side streets to give priority to a bicycle facility.
This design would allow local traffic to turn on the closest corner. but not continue on Royal
Palm. Traffic traveling north or south would be diverted to either Prairie or Sheridan Avenues
and away from Royal Palm. Traffic speeds on Royal Palm would be reduced to 15-20 mph.
Previously staff had estimated a cost of approximately $500,000 to incorporate a Bicycle
Boulevard on Royal Palm Avenue, but that cost included widening the roadway by 8 feet.
removing driveways, swale areas, tree removal and replacing with roadway, stabilizing the sub
grade, adding lime rock, re-grading the swale, adding 2 inches of asphalt, mill and resurface,
adjust inlets, modify the drainage system, and add striping and signage, as well as including
professional fees, permitting and contingency.
This current option does not include widening of the roadway. Staff is currently re-evaluating a
cost for this alternative.
Either way, Miami-Dade County has stated that bicycle boulevards are not part of their adopted
bicycle facility standards or the currently adopted Manual of Uniform Traffic Control Devices
(MUTCD). Such non-standard facilities would warrant an individual traffic flow analysis for which
the County would have to further evaluate on its feasibility and technical functionality. The
County would also require a traffic flow modification application which would warrant two thirds
approval by residents and/or majority approval by the Miami Beach City Commission.
In summary, the process for implementing the above revisions to the plans would be as follows:
• Approval by 2/3 vote from all residents within the Central Bayshore Neighborhood and/or
majority approval by the City Commission.
• 100% vote approval from residents at all intersections along Royal Palm Avenue
between 28 1h Street and 40tt1 Street.
• Once approved by residents and/or Commission, a traffic flow analysis of the entire
Central Bayshore neighborhood must be conducted.

Prairie Avenue Bicycle lane Removal
The scope of work for the removal of the bicycle lanes and reduction in the: width of Prairie
Avenue would require a revision to the stormwater and paving design to include relocation of
the catch basins, removal of 8 feet of asphalt and replacing it with sod, re-grade all the swales,
driveway reconstruction. and lifted grates.
The cost of this request is indicated in Tables A below:

City staff reached out to Miami Dade County Public Works (MDCPW), Traffic Division, to
request their position on this proposed revisions as any modifications of the existing bicycle
lanes along Prairie Avenue, as well as introduction of a bicycle boulevard. would require
MDCPW approvaL The summary of this discussion is as follows:
• MDCPW indicated that approval for the removal of bicycle lanes would not be
considered,
... MDCPW position is that the displacement of an established bicycle facility along a
collector road would be in violation of the Federal Highway Administration Bicycle Policy
which states "under 23 USC Section 109(n), the U.S. Secretary of Transportation shall
not approve any project under this title that will result in the severance or destruction of
an existing major route for non~motorized transportation traffic and light motorcycles,
unless such project provides a reasonable alternate route or such a route exist".
• Florida Statute 335.065 states that "bicycle and pedestrian ways shall be given full
consideration in the planning and development of transportation facilities, including the
incorporaticn of such ways into state, regional and local transportation plan and
programs''.
