AMENDMENT NO. TWO TO CONTRACT K-1213-165: BY AND BETWEEN THE CITY OF NORMAN, OKLAHOMA, AND CABBINESS ENGINEERING, L.L.C., INCREASING THE CONTRACT AMOUNT BY $185,500 FOR A REVISED CONTRACT AMOUNT OF $400,800 TO PROVIDE ADDITIONAL DESIGN SERVICES FOR THE PORTER AVENUE STREETSCAPE BOND PROJECT.
Body
BACKGROUND: The intersection of Porter Avenue and Acres Street has been the subject of much discussion and study over the years, due to concerns over traffic and pedestrian safety. A recent evaluation of traffic control needs revealed that traffic volumes have reached levels that justify the installation of a new traffic signal. Approximately 20,000 vehicles pass through the intersection every day. An aerial photograph of the location is provided in Figure 1, Contract Amendment #1.
On April 25, 2012, staff presented a summary of a report prepared for the Porter Avenue intersection with Acres Street to the City Council Community Planning and Transportation Committee. In the presentation, a number of improvement alternatives were discussed for this location. The presentation included discussion related to the existing in-pavement lighted crosswalk, a recent Safe Routes to School project for Longfellow Middle School and Jefferson Elementary School, and the most recent intersection evaluation including the traffic signal warrant analysis. The alternatives discussed included:
? Staffing the existing pedestrian crossing across Porter Avenue at Acres Street with a Norman Public Schools crossing guard;
? A project to encourage school children to cross Porter Avenue at existing signalized intersections (e.g., Johnson Street or at Gray Street);
? The installation of a mid-block pedestrian signal on the Porter Avenue corridor in reasonable proximity to Acres Street;
? Signalization of the Porter Avenue intersection at Acres Street;
? Construction of a roundabout at the Porter Avenue intersection at Acres Street (as suggested in the Porter Avenue Corridor Study).
