Additional flows will be generated by the project; however, they will be offset by the demolition of the Natural Sciences Building. Portions of the existing sewer infrastructure will be relocated to accommodate the new STEM building. Please find enclosed the following items for your review and approval: • Check in the amount of $480.00 • Fast Track Sewer Application • Flow Tracking/Acceptance for Sewer Extension Applications • Site Maps • 30x42 Plan Sets If there are any questions, please call our office.
