B. Reason for ordering extra work:
The United States Army Corps of Engineers (USACE) made their annual inspection of the City's
levee system the week of December 94' through the 134). During this inspection, four additional areas
of repair in the rip rap were found. These areas are:
• around the outfall for the storm sewer gatewell D- on River Road;
• along the top of levee between the steps and outdoor seating area by the Boathouse;
• a spot location between 184' Street and Blowers Creek;
• around the outfall for the Cedar Bend Street storm sewer pump station.
These areas were not known when the project was developed. A separate project for this small
amount of repairs is not financially responsible and so it was thought prudent by Engineering to add
these repairs into an existing contract and have the issues addressed before spring flooding.
