J4 Re: FREEPORT NORTH — Request for Variance on Pavement Design
Coppell, Texas
Dear Mr. Griffin:
On behalf of Duke Realty Corp., we request that the City of Coppell grant a variance to
the Subdivision Ordinance on the pavement design criteria for the Freeport North
Addition Lot 4R, Block A. Duke 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 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. Jack vans, P.E.
