No. 1200410.A Dear Mr. Weaver: We are submitting for your review and approval revised drawings for the approved BMP at the above mentioned facility. This revision is to repair the forebay berm in the BMP, and does not change the overall BMP design and functionality. During construction, it has been brought to our attention that the forebay berm has been breached due to the occurrence of several large storm events.. The attached docurnents of the plan view and the cross section of the BMP show how we are proposing to revise the approved design to provide reinforcement to the forebay berm by the use of geogrid fabric and riprap. Please notify us at your earliest convenience if these revisions meet your standards so we may notify the contractor to begin this repair work. Sincerely, 16Fredlatkins, Jr., .E.
