SU6�ECT: PAVEMENT AND SIDEWALK AS iESSMENT REPORTS
The purpose of this Letter to Commission is to provide information with regards to assessments
that have been completed on the City's roadways and sidewalks. This effort was undertaken to
develop strategies to maintain and improve the overall rating of these component of the City's
infrastructure.
Jones Edmunds & Associates, Inc. performed the pavement inspections and analysis. This
information was used to develop a Pavement Management System (PMS). The goal of which is
to identify and collect pavement distress information and then use the data to prioritize
maintenance, repair, and construction activities to maximize the effective life of pavement
surfaces at the lowest cost. The pavement information is used to develop a Pavement Condition
Index (CPI), a numerical rating between 0 and 100, 100 being the best condition.
To accurately predict roadway conditions in the future, a deterioration curve is used that will
accurately characterize the PCI degradation over time. The deterioration curve developed by
Florida State University and the Florida Department of Transportation has been incorporated in
the analysis. Pavement deteriorates at an accelerated rate once it reaches a critical point on the
curve which corresponds to a PCI of approximately 55. Below this point, the cost to restore a
roadway is considerably higher than applying preventative maintenance techniques which can
prolong the life of a roadway.
The current overall rating for roadways in the City is a PCI of 70. In five years, if nothing is done
to the roadways, the PCI will be reduced to 47. To maintain a PCI of 70, $6.8 million per year
will need to be spent on roadway preventative and restorative measures. Based on current
funding levels, the overall PCI will decrease over time. The program will enable the Department
of Public Works target methods to minimize the PCI reduction based upon the available budget.
The table of contents and introduction are attached.
Infrastructure Management Services performed a survey of the City's sidewalks. They collected
information of the condition of the sidewalk surface as well as record digital imagery and spatial
coordinate information. The surface distress condition (i.e. cracking fault, scaling, etc.) is the
basis for a Sidewalk Condition Index (SWCI) and is also based on a scale from 0 to 100, 100
being the best condition. However, not all distresses are weighted equally as those distresses
that represent tripping hazards or barriers to those with disabilities have a much higher impact on
the numerical index than other distresses such as spalling or patching.
Following the field surveys, the condition data was assembled to create a single score
representing a particular stretch of sidewalk. The overall citywide SWCI was 72 with the majority
of the sidewalks rated between 60 and 80. However, approximately a quarter of the City's
sidewalks have been rated at or below "marginal" which will require extensive rehabilitation. 20
percent of the sidewalk slabs have moderate stress and 10 percent with severe stress. This
represents 260,000 square yards of sidewalks. Replacement unit pricing is approximately $50
per square yard. The overall present day need is $13.6 million. The report summary is attached.
An evaluation was also performed on the 4775 handicap ramps. 69 sites were identified as
missing or requiring a ramp. Distresses on the ramps were noted and a list of needs developed.
A corrective list has been created grouping ramps with the highest priority given to the ramps
that are the furthest from compliance. There are 736 high priority ramps.
These reports provide the tools necessary to strategically improve the
throughout the City with the budgetary constraints that are mandated.

1.0 PROJECT DESCRIPTION
1.1 PROCEDURE OUTLINE
This report details the findings of a field survey intended to inventory and assess the condition of
sidewalks and ramps within the City of Miami Beach, FL. The IMS approach to this is a three step
process:
1. System Configuration — this step involves identifying all roadways in the City's network,
assigning them a unique identifier, listing their physical characteristics (length, width, etc,) and
demographic attributes (pavement type, functional classification), and linking the network to the
City's GIS map.
2. Field Surveys — following a set of pre-defined assessment protocols in accordance with ASTM
D6433, a specialized piece of survey equipment, referred to as a Sidewalk Surface Tester (SST),
was used to collect observations on the condition of the pavement surface, as well as collect
digital imagery and spatial coordinate information.
Data collected by the SST include:
• Surface Distress — The SST collects surface distress observations based on the extent
and severity of distress encountered along the length of the sidewalk following a modified
version of the ASTM D6433 protocols for concrete pavements. The surface distress
condition (cracking, fault, scaling and the like) is the basis for the Sidewalk Condition
Index.
Not all distresses are weighted equally within the Sidewalk Condition Index. Certain
distresses which represent trip hazards or barriers to those with disabilities, such as
faulting and tilt or divided slabs, have a much higher impact on the condition index than
other distresses such as spalling or patching.
• Slope — Equipped with tiit, grade, and fault meters the SST is able to record the slope of
sidewalk ramps; crucial in assessing ADA compliance.
• Digital video — Fitted with high definition digital cameras the SST is able to record GPS
referenced video used in quality assurance and the creation of image deliverables.
3. Analysis and Reporting - Following the field surveys, the condition data is assembled to create
a single score representing the overall condition of the sidewalk; the Sidewalk Condition Index
(SWCI). Further analysis based on the amount of moderate and severe distress allow for the
creation of a Rehab Index and multiple tables identifying additional asset condition.

2.0 SIDEWALK NETWORK CONDITION AND FINDINGS
2.1 SIDEWALK NETWORK SUMMARY
The surveyed sidewalk network consists of approximately 283 miles of sidewalk with an estimated area of
866,000 square yards. The average sidewalk condition index (SWCI) of the network at the time of survey
was 72 with the majority of sidewalks between 60 and 80. The network is mainly comprised of concrete
slabs, but does have areas of paver bricks and boardwalk. The following table (Table 1) summarizes the
length and area by condition group and neighborhood.

2.2 SIDEWALK CONDITION
Figure 1, on the following page, presents the distribution of �the Sidewalk Condition Index for the complete
network of Miami Beach on a 0 to 100 scale, 0 being worst and 100 being best condition. While the
overall condition of 72 would appear to be acceptable, this is only the case due to the majority of
sidewalks falling into the "Fair" category as seen in Figure 2. With over a quarter of sidewalks rated as
"Marginal" or worse an extensive rehabilitation plan should be considered. This point can be further
justified when reviewing the sidewalk summary (Appendix A at the end of the report and SW_Conditon
tab in the spreadsheet). The amount of slabs with severe distress recorded account for nearly 10% of the
network and slabs with moderate distress recorded account for 20%. Addressing just these distresses
would require maintenance on approximately 260,000 square yards of sidewalk.

With these figures we can estimate the cost to complete this work based on unit pricing of $50 per sq.
yard for 4" thick sidewalk and $60 per sq. yard for 6" thick sidewalk at vehicle crossings. A breakdown of
these costs by neighborhood is located on the following page in Table 2 while costs on a block by block
basis are available in Appendix A and the SW_Condition tab in the accompanying excel spreadsheet.

Taking the approach that it is best to address ramps that are the furthest from compliance first; a ranking
has been created to group ramps by rehab priority, highest to lowest. Figure 3 on the following page
shows the distribution of ramps in these three groups along with the amount of ramps found to be
compliant while Table 4 shows this distribution by neighborhood. A detailed list of sidewalk ramps is
included in the accompanying spread sheet and geodatabase. Ramps are associated with a sidewalk by
Sidewalk_ID and can be easily located in the accompanying GIS files through the use of the Ramp_FID
which is unique to each ramp.
