Dear Ken:
On behalf of Pazk `N Fly, we hereby request that you consider two deviations from the City's policy
regarding private pazking lot specifications.
fl~~. First, we would like to use flyash in our concrete mix design. Attached is the mix design [hat we propose
to use.
~ Second, we would like to use rubber joint sealing compound in lieu of the silicone sealer that the City
t/.~• requires for its public streets~a+t p..r.y Lti~.
Being able to make these two substitutions would be very beneficial to the owner of this project. Given
that they will be maintaining these improvements, it is hard to imagine how this would have a negative
impact on the City of Coppell or its citizens.
Thank you for your consideration of this request.
Sincerely,
NATHAN D. MAIER
