Re~/ FREEPORT Xl & Xl~-~Request for variance on Pavement Design
Dear Mr. Marvin:
On behalf of Duke Construction, we request that the City of Coppell grant a variance to
the Subdivision Ordinance on the pavement design criteria for the Freeport Nodh
Addition Lots 6, 7, Blook A. Duke Construction wishes to eliminate the use of lime
stabilization on this project in order to save on cost associated with the pavement. In
lieu of lime stabilization Duke Construction will increase the concrete strength from 3000
psi to 4000 psi in both public and private pavement areas, but the thickness will not
change. In areas within the public right of way along drive approaches the subgrade will
be composed of a minimum six (6)-inch thick flexible base.
Thank you, for your consideration on this matter. If you have any questions or need any
additional information, please contact me at your convenience.
Sincerely,
C PE
