The major objectives of the TMP are to maintain efficient <br /> and safe movement of vehicles through the construction zone; and to provide intensive <br /> public awareness of potential impacts in the vicinity of the project site. Detour routes will <br /> also be identified and included in the TMP report. <br /> Task 2.9 Drainage Report <br /> AECOM will review the available data and prepare design calculations to assess the <br /> capacity of the existing drainage systems. The Drainage Report will include design <br /> calculations to assess the need for drainage improvements. The results and design <br /> recommendations will be summarized in the Drainage Report. <br /> Page 15 of 42 <br />
