Re: Sandy Lake Project 91-838
(Coppell E. City Limits to Dallas City Limit)
Funding Requirements
Dear Mr. Griffin:
In response to your question posed during our February 23, 1998
meeting on the subject project, the following is offered. The
total length of the project is 2650 linear feet of which 570 linear
feet is in Coppell, 1580 linear feet is in Dallas and 500 linear
feet is in Carrollton. The proportion in each city expressed in
percentages is as follows:
%t~ou%~ ~ City of Coppell 21.51%
City of Dallas 59.62% % ~ %0 ~ %~ ~ 1~%~ ~.~
V~o% ~~ City of, Carrollton 18.87%
~% , Total 100.00%
The above calculation depicts how much of the normal grading,
paving and drainage project costs would be allocated from three
separate cities.
In order to arrive at a representative project cost attributable
between the cities, certain cost components that are directly
accountable from the adjacent projects or project specific items
are listed below.
,~¢, 1. Sidewalk in Coppell and b~een the bridge
~r, and the park entrance (91-83o, copp~il} $11,211
~--~'*$ 2. Permanent fence at Ag. Center and TU property $20,946
~.%s~ (91-830, Coppell)
%~ Carrollton) $9,045
4. 66" storm sewer Line from Carrollton
and flap gate headwall (91-839, Carrollton) $350,000

Sandy Lake Road Project 91-838 (bridge) excluding the bridge items
but including all of the project specific items is $2,634,346.
Subtracting the project specific items results in a grading, paving
and drainage cost of $2,243,144 ($2,634,346 - $391,202). To
determine the amount of Sandy Lake Road Project 91-838 (bridge)
which can be attributed to the other Sandy Lake Road projects by
City we have multiplied the above number by the percentage of
project length or $2,243,144 x 21.51% = $482,501.
Therefore, $482,501 of the Sandy Lake Road Project 91-838 as bid is
eligible for funding from the portion of County 1991 Bond Funds set
aside for the Sandy Lake Road Project 91-830 (from MacArthur
Boulevard to Coppell East City Limits).
You will note from the attached bid tabulation that the amount for
Item 5899, Pavestone, Brick Pavers, requested by the City of
Coppell as shown in Schedule III is $6,552. In addition, the
amount for sidewalk in Coppell and between the bridge and the park
entrance equals $11,211. These two items in the amount of $17,763
are City funded items which are subject to the Interlocal
Agreement.
It is hoped that the above answers the remaining questions you may
have had regarding the funding for the subject project.
Sincerely,
John L. Mears, P.E.
