Dear Mr. Griffin:
With this letter, we are requesting a variance to the standard City requirements for concrete pipe on all
storm drainage. While we will use concrete pipe in all sections within easements and/or City R.O.W., we
would prefer to use PVC for all private drainage systems within our site.
Thank you for your consideration, and we look forward to receiving your reply at your earliest
convenience.
Best regards,
WI/ds
