~ W. ngxneer's Report for the Street Assessment Program
Dear Mayor and City Council Members:
In the fall of 1985 the City Council authorized Ginn, Inc. to
perform a study to determine the estimated costs of construction
and and partial reimbursement through street assessments for the
improvement of Denton Tap Road from Belt Line Road to the north
city limits; and Belt Line Road, east-west, from Denton Tap Road
to the east city limits. The planned improvements to the
roadways were to include six (6) lane divided concrete roadways
and bridges, with concrete curb and gutter, and storm sewer
improvements. Upon completion of the study in the spring of
1986, the City Council took the study under advisement. In a
special workshop meeting held on June 17, 1986 the City Council
developed and adopted a program utilizing $2.6 Million of 1985
Dallas County Bond Funds and City of Coppell Certificates of
Obligation to finance the improvement of Denton Tap Road from
Belt Line Road to the north city limits and authorized Ginn, Inc.
to begin design of the improvements from Belt Line Road to Sandy
Lake Road forthwith. At the February 10, 1987 City Council
meeting the Council approved the addition of four tracts of land
to the Denton County R.U.D. #1 who expressed a desire to have
Denton Tap Road improved all of the way through Coppell and their
district to S.H. 121. Shortly thereafter Ginn, Inc. was
authorized to begin design of the Sandy Lake Road to Denton Creek
portion of the project.
The engineering design, plans and specifications for the project
were completed in January of 1988. The project was approved for
advertisement by the City Manager on January 19, 1988 and was
advertised for bid on January 22, 29, February 5 and 12, 1988.
Bids were received from eleven bidders on March 3, 1988 at
Coppell Town Center with L. H. Lacy Company as the apparent iow
bidder with a Base Bid (6 Lane) of $1,791,535.83.
At it~ regularly scheduled meeting on April 12, 1988, the City
Councll passed a resolution requesting $2.6 Million in funding
from Dallas County under Proposition No. 2 of the 1985 Bond
Program for the improvement of Denton Tap Road from Belt Line

Road to the north city limits, and authorized the Mayor to
execute a Supplemental City/County Agreement providing for such.
On April 18, 1988, the Dallas County Commissioner's Court
approved a Court Order Allowing the County Judge to execute the
Agreement. With funding requirements fulfilled, the City Council
awarded the contract to L. H. Lacy Company at their ~pril 26,
1988 meeting.
It has been the City Council's intention from the beginning to
levy a street assessment for this project in accordance with
state law to recover some of the project costs from the adjacent
benefiting property owners. Since Dallas County has stated that
it is not their current policy to levy assessments on their
projects, the Dallas County portion of the funding for this
project has been subtracted from the assessable construction
costs for the calculation of the assessment rate. The following
calculations of the proposed assessment rate are made in
accordance with the front foot method, and are based on the low
Base Bid (6 Lane) of L. H. Lacy Co.
