SW8 ooloo9 PN 100-014 Dear Mr. Cox, In response to your November 18th inspection report we have enclosed (2) copies of revised plans showing the additional building not shown on permitted plans. The building footprint is 894 sf. with only 552 sf. being new impervious area. The current pond design can handle this additional impervious area. Are we required to obtain a modification for this additional impervious area? We have also proposed to intercept the previously used wash down area into a grease interceptor.. Outflow from this interceptor will be routed to a scour hole and sheet flow into a heavily vegetated woodland area. Roof drains have all been rerouted to the forebay of the basin. I have noticed what I believe to be a mix up in the SW #s and inspection reports. When referring back to the permits it seems as if the inspection report written with SW8 #0030525 should really be for permit SW8#ooloo9 and inspection report for SW8#ooloo9 should be for SW8#030525. Please confirm this for me. Please review for approval and contact us with any questions, comments or additional information needed. Upon approval of these changes we work to provide certification of the stormwater facility. Sincerely, Intracoastal Engineering PLLC Charles D. Cazier, E. 91 Pelican Point Rd.
