Explanation

Background: This legislation authorizes a modification to the design contract with Stantec Consulting Services, Inc. (formerly known as R. D. Zande & Associates) for the Alum Creek Drive widening project. This project is being designed to widen Alum Creek Drive to five lanes and add sidewalks, storm sewers, street lights, curbs, and a shared-use trail on both sides of the street.

The contract modification is necessary for additional topographic survey and plan changes due to development in the project area, for construction engineering and the upgrade of a waterline from a 24 inch line to a 30 inch line. In addition, it was found during the review process that revisions to the post-construction storm water design features would save the city future construction and maintenance costs. These savings will be accomplished by enlarging a retention pond and deleting the manufactured units that collect and clean the storm water runoff. This modification is an addition to the original scope of services but is a continuation of the existing work being performed and it would not be practical to contract with a different consultant.

The Complete Street items for this project include:
· Construction of approximately 4 miles of shared-use trail with connections to the Alum Creek Bikeway and existing sidewalks
· 88 curb ramps
· Shared-use trail conforms to the Bicentennial Bikeway Master Plan.

Currently, no COTA buses serve this area.

Environmental enhancement: The retention pond will significantly improve the post-construction storm water quality by separating out suspended particles and pollutants and by reducing the velocity of the storm water at the receiving stream.
