REF: Escrow #02 and#04 for Coppell Road (ST00-03)
On January 15, 1989, Centex escrowed $56,891.00 to the City of Coppell for the future construction
of Coppell Road adjacent to Shadowridge Estates III. Also, on July 19, 1989, Centex escrowed
$90,070.00 to the City of Coppell for the future construction of Coppell Road adjacent to
Shadowwood Estates. On June 24, 2003, the City of Coppell awarded a design contract to Huitt-
Zollars, Inc. in the amount of$200,000.00. And, on April 8, 2008, the City of Coppell awarded a
construction contract to Tieso Paving in the amount of$3,057,846.30.
The question has been raised as to whether or not the original escrow amount exceeded the actual
cost of the road. The original escrow amount was based on a fee of$100 per adjacent front foot.
Shadowridge Estates III had 568.73 feet adjacent to Coppell Road and Shadow Estates had 900.06
feet adjacent to Coppell Road. Therefore, the escrow amount was arrived at by multiplying the
adjacent front foot times $100.00 (568.73 x 100 = $56873 and 900.06 x 100 = $90006. —rounding
on the adjacent front foot likely accounts for the slight discrepancy).
The front cost is made up of several cost components. Those are: excavation; subgrade preparation;
lime; paving; sidewalk; drainage; incidentals; and engineering. The final construction cost of the
project was $2,966,679.36 (a slight savings). Of that amount, $380,682.90 was for a new water
line. Therefore, the total construction cost to be apportioned to the adjacent property is
$2,585,996.60. In addition to that, the engineering costs $191,023.90. The percentage of the water
line cost versus the total project cost is 12.83% (380,023.90/2,966,679.36). Therefore, 12.83% of
the engineering cost is deleted making the engineering cost associated with the paving $166,511.80
(191,023.90 - .1283 x 191,023.90). Using the above bolded and underlined numbers, the actual
street cost was $2,752,478.40. And the length of the project was 3,400 feet. Because there are two
sides to the road,the actual length used to calculate the front foot cost is 6,800 (2 x 3,400).
Finally, the front foot cost for property adjacent to Coppell Road is $404.78. This is over four times
higher than the amount escrowed with the city in 1989.

REF: Escrow #12 for Coppell Road (ST00-03)
On January 9, 1991, Pulte Homes escrowed $72,990.00 to the City of Coppell for the future
construction of Coppell Road adjacent to Devonshire. On June 24, 2003, the City of Coppell
awarded a design contract to Huitt-Zollars, Inc. in the amount of $200,000.00. And, on April 8,
2008, the City of Coppell awarded a construction contract to Tieso Paving in the amount of
$3,057,846.30.
The question has been raised as to whether or not the original escrow amount exceeded the actual
cost of the road. The original escrow amount was based on a fee of$100 per adjacent front foot.
Devonshire has 729.90 feet adjacent to Coppell Road. Therefore, the escrow amount of$72,990
was arrived at by multiplying the adjacent front foot times $100.00 (729.90 x 100 =$72,990).
The front foot cost is made up of several cost components. Those are: excavation; subgrade
preparation; lime; paving; sidewalk; drainage; incidentals; and engineering. The final construction
cost of the project was $2,966,679.36 (a slight savings). Of that amount, $380,682.90 was for a
new water line. Therefore, the total construction cost to be apportioned to the adjacent property is
$2,585,996.60. In addition to that, the engineering cost $191,023.90. The percentage of the water
line cost versus the total project cost is 12.83% (380,023.90/2,966,679.36). Therefore, 12.83% of
the engineering cost is deleted making the engineering cost associated with the paving $166,511.80
(191,023.90 - .1283 x 191,023.90). Using the above bolded and underlined numbers, the actual
street cost was $2,752,478.40. And the length of the project was 3,400 feet. Because there are two
sides to the road, the actual length used to calculate the front foot cost is 6,800 (2 x 3,400).
Finally, the front foot cost for property adjacent to Coppell Road is $404.78 ((2,585,996.60 +
166,511.80)/6800)). This is four times higher than the amount escrowed with the city in 1991.
