Structural engineer's preliminary sketches and calculations.
Plan and profile sheets at the proposed culvert installations.
Revised schedule.
The following reflects our understanding of the items discussed during the subject meeting. If
you do not notify us within five working days, we will assume that you are in agreement with our
understanding.
Item Description Action By
1.00 TECHNICAL
1.01 Introductions/PACER
The meeting began at approximately 9:05 am.
1.02 General Update and Review Items
Due to back-water problems at the culvert under Bethel Road, water
surface elevations at this culvert have not been finalized. Grading of the
downstream channel at the culvert under Coppell Road was also
discussed to help alleviate the back-water problem. This option produced
negligible results within the limits of this project. It was determined that
upstream detention may be a strong alternative to the back-water
problem. Keith Marvin offered to contact Transystems for the final water KM
surface elevation (WSE) at the Bethel Culvert.

1.03 Downtown Area
Suzan Taylor provided a copy of the letter to FNI that thc City drafted to
Steven Chaddick, owner of the property at 501 Bethel Road. This letter
explains the assumptions and outlines the parameters for safe operation
of a driveway in the intersection of Coppell and Bethel Rds. Keith
CLM
suggested a revision to the signal phasing at this intersection to allow a
protected left turn for eastbound traffic. New concrete driveways were
also considered for properties adjacent to the downstream side of the
Bethel culvert in order to accommodate the proposed grading to Bethel
Road.
1.04 Bridge Construction
FNI presented the layouts that were prepared by FNI's structural
engineers. An alternative to the proposed bridge construction was using a
single span beam utilizing a Type 1V TxDOT beam. This alternative
would provide a cheaper cost and faster construction time. FNI informed
the City that closing Bethel Road for the duration of the demolition and
reconstruction of the bridge was the preferred alternative. Chris
Moorman informed the City that preliminary estimates for time of
demolition and reconstruction of the bridge, using the single span
approach, could take place within a 6-8 month timeframe. Suzan
requested FNI provide the City 3 alternatives with a cost estimate and
projected construction time for each. The alternatives are as follows: CLM
-Closing Bethel Road for the entire duration of demolition and
reconstruction,
-Building the bridge in half-widths while maintaining one lane of thru
traffic,
-Constructing a temporary structure to accommodate two-way traffic
during the duration of demolition and reconstruction.
FNI also presented the City with 2 options for a proposed bridge section.
These options depicted the various parapet wall heights and the use of an
internal parapet wall behind the curb. Chris Moorman noted that the
interior rail/wall is recommended (according to AAgHTO) for roadway
speeds of 40 mph or greater, that option would not be applicable since the
posted speed for the roadway is 30 mph. Direction was given to research CLM
AASHTO for Hike/Bike trails for wall heights along bridges and to
contact the City's park's department for input on the Hike/Bike area.

INNOVATIVE APPROACHES...PRACTICAL RESULTS
1.05 Denton Tap Intersection
CLM
Chris Moorman explained that the proposed alterations to the Denton Tap
median noses needed to accommodate the widening of Bethel Road at the
Denton Tap intersection. Tricia Hatley informed the City that this cost
was not in the original preliminary estimate.
1.06 Proposed Improvements to Traffic Signalization
Keith Marvin had questioned the proposed replacement of the southwest CLM
pole (P3). After the widening of Bethel Road at Denton Tap, does the
pole have to be relocated? Chris Moorman will address this issue with
FNI's traffic signal designer and provide an answer. Chris Moorman also
asked if the Coppell/Bethel intersection could be temporarily changed to
a 3-way stop during the signal construction. This would eliminate the
need for a temporary span wire installation and more ease of
construction. Chris Moorman also enquired about city details concerning
traffic signal construction. The City explained that the Natchez Trace
plans were a complete set of traffic signal plans. Chris Moorman asked if
there were other details required for the plans, would TxDOT standards
be permissible to use and the City agreed. Chris Moorman also enquired ST
about the General Notes from the Natchez Trace plans and asked to
obtain an electronic copy of the notes and Suzan Taylor mentioned she
could send an electronic copy of them.
