NEW BUSINESS
2. Discussion and consideration of an item authorizing the Public Works Director to proceed
with the installation of bike lanes along Cummings Drive from SH121 to Forest Ridge Drive
and approving funding for the project.
Public Works Director Kenny Overstreet presented information on this item, which is to request bike
lanes along various roadways, including Harwood Road and Cummings Drive. Staff estimates that
the project will cost $100,000 for pavement markings and signage. Tarrant County Commissioner
Gary Fickes has offered to assist with the cost of installation.
Motioned by Director Epstein, seconded by Director Boyter, to approve funding for the installation of
bike lanes along Cummings Drive from SH121 to Forest Ridge Drive.
Motion passed 6-0-0. President Turner declared the motion carried.
3. Discussion and possible action on the street assessment and guidance on the Street
Improvement Economic Development Corporation board members’ expectation for street
rehabilitation.
4. Discussion on potential funding options for future street rehabilitation upon completion of
the street assessment.
Items number 3 and 4 were presented together.
Public Works Director Kenny Overstreet presented information on item number 3, which is
requesting guidance on the type of street maintenance process the board prefers: micro sealing,
slurry seal or mill and asphalt overlay.
Assistant City Manager Cliff Blackwell presented information on item number 4, which is a
discussion on potential funding options. Mr. Blackwell stated that the Series 2005 GO’s will be rolling
off the books in 2019. He presented information on borrowing funds within the 4B fund for future
street rehabilitation projects. Mr. Blackwell stated that each year, the 4B generates a revenue
stream of approximately $2.5M and debt service payments have been $1.3M. The following funding
options were presented to the Board:
Scenario number one will keep the debt service amount at what is currently budgeted and
paid out over 20 years, with $18.7M being the total amount borrowed.
Scenario number two will span 30 years, increasing the borrowing capacity from $18.7M to
$22.2M while maintaining the same debt service payment of $1.3M annually.
Scenarios number 3 and 4 maximize the amount that can be borrowed over 20 years and 30
years, assuming the same level of income is maintained in the 4B fund, which is $2.5M and
making the entire debt service payment $2.5M, and that the amount borrowed over 20 years
is $33.7M, and over 30 years is $40M.
In addition to debt service, the 4B funds supply needs: sign maintenance, sidewalk maintenance,
striping bicycle lane (if approved), which borrowed funds cannot pay for.
Mr. Blackwell stated that scenario 4, 30-year, allows the maximum amount of money to be
borrowed. Those funds would have to be used towards a capital improvement that out lasts the
amortization. Regarding the mill and overlay, it does not make financial sense to use that type of
bond, over that period for something that does not last that long.
Mr. Blackwell stated that there is no minimum reserve requirement for 4B, except the amount to
cover debt.
Motioned by Director Boyter, seconded by Director Epstein to recommend that the goals of the
rehabilitation plan be:
70% result
5 to 10-year completion
Utilizing all three street maintenance processes: micro seal, slurry seal, and mill and asphalt
overlay
Motion passed 6-0-0. President Turner declared the motion carried.
5. Discussion and consideration of an item authorizing the Public Works Director to proceed
with submitting Requests for Qualifications to engineering firms to complete a Traffic Signal
System and Intelligent Transportation System (ITS) for the City of Bedford and, when
completed, applying for various grant opportunities.
Public Works Director Kenny Overstreet presented information on this item. Mr. Overstreet stated
that this item is to get Board approval to submit Requests for Qualifications to complete a Traffic
Signal System and Intelligent Transportation System for the City. Staff will also apply for various
grant opportunities for this project.
Motioned by Director Boyter, seconded by Director Sartor to authorize staff to proceed with
submitting Requests for Qualifications to engineering firms to complete a Traffic Signal System and
Intelligent Transportation Systems for the City of Bedford.
Motion passed 6-0-0. President Turner declared the motion carried.

5. Consider authorizing the Public Works Director to submit a request to the City Council to enter
into a contract with Fugro Roadware, Inc. to complete a street rating system, utilizing the North
Central Texas Council of Governments (NCTCOG) Interlocal Share Program.
Kenny Overstreet, Public Works Director, presented on this item, which is to authorize the Public
Works Director to submit a request to Council to enter into a contract with Fugro Roadware, Inc. to
complete a street rating system. The scope of work will include pavement data collection, sidewalk
and ADA ramp data collection, pavement management analysis and report and deliver data in a
Geographic Informational Services (GIS) format.
In response to questions from the Board, all bidders were given the same bid specs; that it is typical
to utilize interlocal agreements; and that project completion is dependent upon funding and Council
approval.
Motioned by Director Fisher, seconded by Director Boyter to authorize the Public Works Director to
submit a request to the City Council to enter into a contract with Fugro Roadware, Inc. to complete a
street rating system, utilizing the North Central Texas Council of Governments (NCTCOG) Interlocal
Share Program.
Motion passed 7-0-0. President Turner declared the motion carried.
6. Consider authorizing the Public Works Director to submit a request to the City Council to enter
into a contract with Ace Asphalt to complete repairs on Harwood Road, utilizing the interlocal
Purchasing System (TIPS/TAPS) contract.
Kenny Overstreet, Public Works Director presented on this item, which is to authorize the Public Works
Director to submit a request to Council to enter into a contract with Ace Asphalt to complete repairs
on Harwood Road, utilizing TIPS/TAPS. It has been determined that there are 12 locations with
subgrade failures on Harwood Road. Ace Asphalt will address the failures by milling, doing a 10-inch
compaction, cover with new subgrade and new asphalt. The majority of Harwood Road is structurally
solid, however the micro-seal is flaking. The Board was of the consensus to direct staff to include
Harwood Road from SH 121 to FM 157, in the amount of $193,000 utilizing the 4B fund balance.
Motioned by Director Fisher, seconded by Director Epstein to authorize the Public Works Director to
submit a request to the City Council to enter into a contract with Ace Asphalt to complete repairs on
Harwood Road, utilizing the interlocal Purchasing System (TIPS/TAPS) contract.
Motion passed 7-0-0. President Turner declared the motion carried.
7. Discussion and possible action regarding Harwood Road restoration options.
Tarrant County is willing to assist with an overlay on the roadway, which provides a significant savings.
Staff recommends beginning this year with the east and west bound lanes between Central Drive and
Forest Ridge and over the next three years complete the remainder of Harwood. There are
infrastructure issues to be repaired/renewed, curb and gutter repairs to be made, ADA ramp and
AGENDA
sidewalks to be installed. Funding will come from the $750,000 set aside previously for the Harwood
Road Project.
NCTCOG notified staff that they are no longer interested in having conversations about Harwood
Road, but are interested in assisting with traffic signalization.

PRESENTER: Kenneth Overstreet, Public Works Director DATE: 05/01/18
ITEM:
Discussion and consideration of an item authorizing the Public Works Director to proceed with the
installation of bike lanes along Cummings Drive from SH121 to Forest Ridge Drive and approving
funding for the project.
DISCUSSION:
Staff has received multiple requests for bike lanes along various roadways that include Harwood
Road and Cummings Drive. At the time, staff planned on installing bike lanes along Harwood
Road during the reconstruction of the roadway, but after grant funding was denied for the
project, the reconstruction was delayed.
During a meeting with Tarrant County Commissioner Precinct 3 Gary Fickes, regarding Harwood
Road, the idea of moving the bike lanes to Cummings Drive was discussed. Commissioner Fickes
offered assistance in the cost of installation.
Staff began looking at the feasibility of the installation of bike lanes along this section of the
roadway. It was determined that bike lanes would be possible with various sections being
designated bike lanes and some areas with signage added to share the road.
The shared bike lanes would be needed at all major intersections, except Murphy Drive. This
location would retain the full bike lane through the intersection.
Staff requests authorization to install the bike lanes on Cummings Drive from SH121 to Forest
Ridge Drive and request authorization for funding for the pavement marking installation. The
estimated cost for the pavement marking installation and signage is $100,000, which would be paid
out of the contract labor line item in the SIEDC budget.
A financial analysis concludes that the fund balance will accommodate the funding for bike lane
installation on Cummings Drive from SH121 to Forest Ridge Drive.

AGENDA
PRESENTER: Kenneth Overstreet, Public Works Director DATE: 05/01/18
ITEM:
Discussion and possible action on the street assessment and guidance on the Street Improvement
Economic Development Corporation (SIEDC) board members’ expectations for street rehabilitation.
DISCUSSION:
Staff presented an item to the SIEDC during the January 16, 2018 meeting, for approval to submit a
request to City Council to enter into a contract with Fugro Roadware, Inc. to complete a street
assessment. The item was approved by the SIEDC on January 16, 2018 and by City Council at the
February 13, 2018 meeting. The street assessment results require input from the City to complete the
analysis. The items include type of maintenance allowed, what the long term goals regarding desired
pavement condition levels will be and if the City would like a five or ten year rehabilitation plan.
One type of street maintenance used in the past is micro seal. This process, which consists of a thin
layer of material coating the existing asphalt street, was completed on Harwood Road, Forest Ridge
Drive and Bedford Road. The preventive maintenance has an approximate life span of seven years
on less traveled roads before additional preventative maintenance is required. Micro seal can be
completed three times before the road will require a mill and asphalt overlay or reconstruction.
Another option for preventive maintenance is completing a slurry seal. A slurry seal is the application
of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an
existing asphalt pavement surface. This procedure was completed in various parking lots at the Boys
Ranch Park.
The cost to micro seal a road is less than the cost for a mill and asphalt overlay. During the
presentation at the January 16, 2018 meeting on the street assessment, staff informed the SIEDC that
the cost variation between micro seal and mill and asphalt overlay, on streets over 40 years old, was
$1,443,000.
Staff is requesting guidance on whether the SIEDC will permit micro sealing to be used on City
streets, slurry seal or if mill and asphalt overlay is the preference.
In order for the rehabilitation plan to be completed, staff will need to inform Fugro Roadware, Inc. on
the long term goals regarding desired pavement condition levels and if it will be a five or ten year
rehabilitation plan. The desired pavement condition level is the percentage of the City’s street
network that is in good to excellent condition. For example, if 70% is the desired result, this will mean
that 70% of the street network is in good to excellent condition. The higher the pavement condition
level and the length of the plan will determine the annual cost to complete the street rehabilitation.
Staff is requesting guidance from the SIEDC to determine the expectation for these items.

N/A Micro Seal Photo
Slurry Seal Photo and Information
Cost Summary from January 16, 2018
AGENDA
Slurry Seals
What? A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small
crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog
seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the
emulsion and aggregates represents “slurry.” Polymer is commonly added to the asphalt emulsion to
provide better mixture properties. The placement of this mixture on existing pavement is the “seal” as
it is intended to seal the pavement surface. Slurry seals are generally used on residential streets.
Why? Slurry seal is applied in order to help preserve and protect the underlying pavement structure
and provide a new driving surface. Roads chosen for slurry seal applications generally have low to
moderate distress and narrow crack width. Slurry seal applications serve to seal the cracks, restore
lost flexibility to the pavement surface, provide a deep, rich black pavement surface color, and help
preserve the underlying pavement structure.
When? Slurry seal is typically applied on either an intermittent or cyclical basis. Location, weather,
traffic loading, and pavement conditions are factors used to determine if a slurry seal application is
appropriate. Roadways selected for slurry seal treatment are commonly those which have slight to
moderate distress, no rutting, and generally narrow crack widths, and where a slurry seal treatment
would help extend the pavement life until resurfacing becomes necessary.
Roadways chosen for cyclical slurry seal applications would typically be treated every five to seven
years.
How? The asphalt emulsion and the aggregates are mixed in, and applied using, a purposely built
truck, generally referred to as a “slurry truck.” Yes, I know, that’s rather obvious, but I didn’t make it
up!
Slurry trucks contain various compartments which hold the aggregate (fine crushed rock), water,
polymer modified emulsion, and other additives, which are mixed in the on-board mixer. The slurry
mixture flows out of the rear of the truck and onto the pavement within the confines of a box attached
to the rear of the truck. The box serves to distribute the slurry mixture over the pavement. Workers
with squeegees follow behind and assist in spreading the mixture, correcting areas not properly
covered, and keeping the mixture off of concrete improvements such as gutters.
AGENDA
A piece of burlap is often dragged behind the slurry truck with the goal of producing a smooth texture
while spreading the slurry seal. The texture of a slurry seal is different than that of asphalt pavement.
The texture may have faint lines and be somewhat coarse. In addition, when the slurry is first placed
the surface is tender and can be marked up by sudden turning movements. These impressions on the
pavement are temporary as seasonal weather and traffic smooth out these imperfections over time.
AGENDA
Once placed slurry seals need 4 to 6 hours to set or harden before the road is open for traffic.
AGENDA
AGENDA
Microsurfacing
What? Microsurfacing is similar to slurry seal. It consists of the application of a mixture of water,
asphalt emulsion, aggregate (very small crushed rock), and chemical additives to an existing asphalt
concrete pavement surface. Polymer is commonly added to the asphalt emulsion to provide better
mixture properties. The major difference between slurry seal and microsurfacing is in how they
“break” or harden. Slurry relies on evaporation of the water in the asphalt emulsion. The asphalt
emulsion used in microsurfacing contains chemical additives which allow it to break without relying on
the sun or heat for evaporation to occur. Thus, microsurfacing is an application that hardens quicker
than slurry seals and can be used when conditions would not allow slurry seal to be successfully
placed. Streets that have a lot of shade and streets that have a lot of traffic are good candidates for
microsurfacing.
Why? Microsurfacing is applied in order to help preserve and protect the underlying pavement
structure and provide a new driving surface. Roads chosen for microsurfacing application generally
have low to moderate distress and narrow crack width.
When? Microsurfacing is typically applied on an intermittent, project-specific basis. Location,
weather, traffic loading, and pavement conditions are factors used to determine if a microsurfacing
application is appropriate. Roadways selected for microsurfacing treatment are commonly those
which have slight to moderate distress, no rutting, and generally narrow crack widths, and in which a
microsurfacing treatment would help extend the pavement life until resurfacing becomes necessary.
Roadways chosen for cyclical microsurfacing applications would typically be treated every five to
seven years.
AGENDA
How? Microsurfacing is commonly mixed in, and applied using, a purposely built truck, generally
referred to as a “slurry truck.” If the roadway segments to be microsurfaced are long and don’t contain
sharp curves, a “continuous machine” is sometimes used. This machine is capable of constant or
continuous mixing and application of microsurfacing due to its large storage compartments and
capability to attach to aggregate delivery trucks and tankers containing microsurfacing emulsion. This
continuous operation provides the benefit of having few if any seams in the roadway which occur
when operation stops.
Slurry trucks and continuous machines contain various compartments which hold the aggregate (fine
crushed rock), water, polymer modified emulsion, and other additives, which are mixed in the on-
board mixer. The microsurfacing mixture flows out of the rear and onto the pavement within the
confines of a rear-mounted box referred to as a “micro box.” This box contains an auger which turns
to uniformly distribute the mixture across the width. Workers with squeegees follow behind and assist
in spreading the mixture, correcting areas not properly covered, and keeping the mixture off of
concrete improvements such as gutters.
A piece of burlap is often dragged behind with the goal of producing a smooth texture while applying
the microsurfacing material. The texture of microsurfacing is different than that of asphalt pavement.
The texture may have faint lines and be somewhat coarse. In addition, when the microsurfacing is
first placed the surface is tender and can be marked up by sudden turning movements. These
impressions on the pavement are temporary as seasonal weather and traffic smooth out these
imperfections over time.
Once placed microsurfacing needs 1 to 2 hours to set or harden before the road is open for traffic.

ITEM:
Discussion and consideration of an item authorizing the Public Works Director to proceed with
submitting Requests for Qualifications to engineering firms to complete a Traffic Signal System and
Intelligent Transportation System (ITS) for the City of Bedford and, when completed, applying for
various grant opportunities.
DISCUSSION:
In 2011, the City completed a State Energy Conservation Office (SECO) grant funded project to
upgrade and synchronize the City maintained traffic signals. As with other types of electronics, the
traffic signal equipment is at its end of life, requiring additional maintenance or replacement with
upgraded technology.
