Pursuant to our earlier telephone conversation, I am enclosing three updated Preliminary Storm Drainage
Reports that incorporate an alternative water treatment device as allowed in your February 23, 20071etter.
The revised preliminary site and engineering plans that were submitted April 25, 2007 to your office
already incorporates this same type of treatment device as discussed in your letter.
Please route these updated preliminary reports to your engineer for review. Should you have questions or
need additional information, please contact Nana Halvorsen or me at this office. Thank you.
Respectfully,
Hal P. Grubb, P.E.
