We are requesting a plan revision for the above referenced project. Enclosed
please find two (2) sets of plans and a revised page 2 of the permit application. The
proposed plan reduces the total impervious area by 1,804 sf, however the pond design
will remain the same.
Please review for approval and contact us with any questions, comments or if
you need additional information. Thank you.
