BDD Project No. C03i62
Dear Ms, Turner:
At this time Brockette-Davis-Drake, Inc. respectfully requests that the city allow 4000 psi concrete to be
used on our project site. This is in lieu of using 3500 psi concrete with a lime stabilized subgrade. We
request this under the understanding that any paving in the public R.O.W. still requires a flex-base
subgrade.
Sincerely,
BROCKETTE-DAVlS-DRAKE, inc.
Brandon W. O'Donald, P.E.
