Locations, existing information, proposed lengths, and sizes are estimated only and should not be ordered until measured to match field conditions and submitted in writing to the CO. Obtain CO approval prior to ordering material.

Replace culverts within existing flowlines, unless otherwise noted or directed by the CO. Extend culverts to keep headwalls outside the design clear zone, as directed by the CO. Adjust inverts to meet field conditions, minimum cover, and typical sections, as directed by the CO.

Regrade all areas (inlet and outlet) to draIn. Remarks for "Grade to drain" and "Recondition ditch" indicate existing drainage is poor.

The connection of new pipe to an existing inlet and bricking of the curb opening for EX-I2 and EX-I3 is considered incidental to the installation of the pipe.

Removal of the broken headwall and seperated pipe section at station 52+11 of the parking lot is paid for as removal of pipe end section.
