MEMORANDUM
TO: Mayor and City Council
FROM: Kenneth M. Griffin, P.E., Director of Engineering/Public Works
DATE: April 12, 2011
REF: Discussion regarding reducing Deforest Road to one lane eastbound from
MacArthur Blvd. to Allen Road for the duration of the construction project.
For some time, the City of Coppell has been working on the redesign of Deforest Road from
MacArthur Blvd. east to the Windsor Estates subdivision. The Deforest Road project consists of
the removal of the existing asphalt roadway and the construction of a new concrete street with
improved drainage and sidewalks on both sides. There will also be a signal light constructed at
the intersection of Deforest Road and MacArthur Blvd.
Because of the narrow width of the existing roadway and the existing development, there is very
little room available to construct enough roadway to maintain two way traffic. Therefore, during
the duration of the project, Deforest Road will be one -way from MacArthur Blvd. east to Allen
Road. The eastbound direction was chosen because of the need to quickly gain access to the area
during emergency responses.
With this agenda item, an Exhibit has been provided to show the detour during construction.
Basically, residents on the north side of Deforest Road between MacArthur Blvd. and Allen
Road will be required to head east to Lake Forest Road or Allen Road to exit the area during
construction. They will use Deforest Road eastbound to return to their property.
It is anticipated that this project will begin this summer. All right of way has been acquired for
this project and utilities have been relocated. A letter with a detour route will be mailed to each
resident in the area generally north of Deforest Road, along Lake Forest Road and Allen and in
Windsor Estates.
The tricky part of this construction will actually be the stretch of Deforest Road between Allen
Road and Windsor Estates. There is a need to maintain two -way traffic on that stretch of the
roadway so residents in Windsor Estates can both exit and return to their subdivision. However,
there is not adequate room in the current right of way to build two lanes of travel. There are
several alternatives that will be explored with the lowest responsible bidder. One is the
installation of temporary traffic signals at Windsor Estates and at Allen Road that would control
direction of traffic on the roadway. This approach has recently been successfully used on several
projects in neighboring communities. The other option that could be available to the lowest
responsible bidder would be to obtain a temporary easement from the property owners on the
north side of Deforest Road to build an additional lane of asphalt on their private property during
construction. The contractor would need to negotiate with the property owners to gain approval
for this option and then return the area to as good or better condition after construction. To
expedite the construction of Deforest Road, the City is offering a bonus. If the section between
Allen Road and Windsor Estates is re- opened to two -way traffic within 28 calendar days, the
contractor will receive a bonus of $24,000. If the road is not open to two -way traffic within 28
calendar days, then the contractor will begin incurring a $2000 a day liquidated damages. There
is no limit on the amount of liquidated damages. Also, the overall project has an incentive bonus
to expedite construction because of the inconvenience of the one way traffic on Deforest Road.
The City of Coppell Code of Ordinances, Section 8 -2 -13 "Authority to temporary close streets"
allows the City Manager or his designee to temporary close streets during construction so long as
adequate notification is provided prior to the closing of any streets or portion thereof.
The agenda item this evening is presented for purposes of public notification concerning the
future construction of Deforest Road and the need to temporarily make it one way during
construction. As previously stated, individual letters will also be mailed to affected property
owners along with inforination in the Water Bill insert, and on the City's website.
Staff will be available to answer any questions at the Council meeting.
