A RESOLUTION AUTHORIZING THE CITY MANAGER TO NEGOTIATE A CONTRACT WITH MATRIX DESIGN GROUP, INC., FOR THE FINAL ENGINEERING DESIGN FOR THE E. 56TH AVENUE RECONSTRUCTION BETWEEN BRIGHTON BLVD AND VASQUEZ BLVD.

Summary & Background
The Consultant will perform design services to provide the City with final engineering and construction bidding documents for the reconstruction and widening of E. 56th Avenue from Brighton Blvd to Vasquez Blvd.
East 56th Avenue was identified within the City of Commerce City’s Transportation Plan (2010) as a recommended candidate for roadway widening to provide capacity improvements. The purpose of this agreement is to take the preliminary engineering design for the roadway, which was completed under a previous contract, to final design and produce final engineering drawings and documents for construction. E. 56th Avenue is classified as a minor arterial through the proposed area of reconstruction. This Project includes the segment of E. 56th Avenue from Brighton Blvd. east to Vasquez Blvd, it does not include the intersections at each end, and is approximately 0.8 miles in length. Currently, this section of roadway is a two-lane road with seven railroad crossings, no infrastructure to accommodate pedestrian traffic and minimal street lighting. This project will add a center, continuous two-way left turn lane, 5-foot sidewalks for pedestrian traffic, improve drainage, improve stormwater runoff water quality, which drains directly to the Sand Creek, and much needed repair to the roadway and railroad crossings.
A traffic study was completed during the preliminary design phase of the project and it was determined that the current two-lane roadway is adequate to support forecasted traffic volumes. Due to the several driveways on E. 56th Avenue for the different businesses, left turn queuing is an issue for traffic operations. The two-way left turn lane will improve traffic operations associated with turning vehicles....
