Coppell, Texas
Dear Mr. Garza:
Please accept this letter as our request for a variance from the City of Coppell’s pavement subgrade
requirements. In lieu of the City’s required lime stabilized subgrade, this project is proposing adding an
additional inch of concrete in the firelanes to a total of 7” thickness over 6” compacted subgrade. All
vehicular parking pavement will remain at 5” thickness over compacted subgrade.
Please feel free to call me with any questions or concerns.
Sincerely,
SPIARS ENGINEERING, INC.

Kevin,
We need a letter from you stating that you would like a variance from our subgrade requirement. We are ok with it
however, we require the pavement to increase by an inch. So the fire lane will need to be 7" instead of 6" and the
parking will need to be 6" instead of 5". I also noticed and I should have made the comment but we have switched our
standard details to show#4 bars on 18" centers.

Michael,
One question I got from the Contractor is regarding the need for lime stabilized subgrades. Our Geotechnical report
does not identify Lime as a requirement and City Detail 2300 notes that"alternative subgrades supported by lab tests
may be submitted to City for approval". I've attached the report for your use and would like to request the alternative of
not using lime.
Thanks.
