J4 Re SAINT ANN CATHOLIC PARISH
Coppell, Texas
Dear Mr Marvin
On behalf of The Roman Catholic Diocess of Dallas, we request that the City of Coppell
grant a variance to the Subdivision Ordinance on the pavement design criteria for the St.
Ann Catholic Parish The Roman Catholic Diocess of Dallas wishes to eliminate the use
of lime stabilization on this project in order to save on cost associated with the
pavement.
The geotechnical report recommends five inches of concrete pavement for automobile
parking lots, a minimum of six inches for areas subject to truck traffic, and a minimum of
seven inches for dumpster trash pick up aprons Rigid (concrete) pavements may be
placed on an unstabilized, properly compacted subgrade The concrete should have a
minimum 28 -day compressive strength of 3,000 psi in automobile lots and 3,500 psi in
Medium Duty Traffic areas
In order to meet the City of Coppell pavement standards, The Roman Catholic Diocess
of Dallas will increase the strength of the concrete in parking areas, firelanes, and
dumpster areas to 3,600 psi
To meet the lime stabilization variance for the City of Coppell, The Roman Catholic
Diocess of Dallas will increase the pavement thickness from six inches to seven inches
in proposed firelanes, however, they would like to follow the geotechnical
recommendation of 5 inches of concrete pavement in parking areas with a 28 -day
strength of 3,600 psi
Thank you for your consideration on this matter If you have any questions or need any
additional information. please contact me at your convenience
Sincere ,
