2018-007 Small Intersection Improvement ProjectsDate: January 19, 2018 Report No. 2018-007 INFORMAL STAFF REPORT TO MAYOR AND CITY COUNCIL SUBJECT: Small Intersection Improvement Projects EXECUTIVE SUMMARY: City Council recently approved funding for design and construction of Small Intersection Improvement Projects at six (6) locations throughout the City. The majority of the locations currently experience considerable traffic congestion during morning and afternoon peak hours. As such, staff identified capacity and signal enhancements at each location that would help alleviate the existing traffic issues. This report provides an overview of the proposed plan to design and implement (construct) these small intersection improvements. The goal is to complete these projects by end of 2018. BACKGROUND: At the August 26, 2017, City Council Retreat, the City Council gave direction to Staff to develop a short term plan that would make immediate traffic flow improvements within the City. As a result, traffic engineering staff identified six intersection improvements that would address citizen complaints, alleviate congestion, and improve safety. The intersections were identified based on the amount of traffic congestion, the ease of design and implementation, and the immediate and noticeable impact to drivers. In the December 12, 2017 meeting, City Council approved funding for the six Small Traffic Improvement Projects. The estimated cost of the projects is shown in the table below. Project Short-Term Improvement Estimated Cost Colorado Blvd/Loop 288 Extend the eastbound left turn lane $200,000 Country Club Rd/Hickory Creek Rd Add a westbound right turn lane $150,000 US 77-Dallas Dr/Teasley Ln Add turn lanes, channelized islands $725,000 Bell Ave/McKinney St Add a northbound right turn lane $120,000 Carroll Blvd/Sherman Rd Add a northbound left turn lane and improve the turning radius on the south-east corner $425,000 University Dr/Old North Rd Add left turn lanes (north-south) $500,000 Total $2,120,000 PROJECT STATUS: Since, the City Council approval staff has worked on soliciting, reviewing, and shortlisting qualified design firms suitable for these projects. Staff intends to engage the services of six different design firms (one for each project) to expedite the design process and move the projects on parallel tracks. The design for all the projects is anticipated to be completed by April 2018. Subsequently, the projects will be divided into two groups with three projects in each group. The bundled projects will be advertised and bid as two separate contracts for construction. The bid Date: January 19, 2018 Report No. 2018-007 and award phase is anticipated during the summer months with the construction starting in fall and completion by end of 2018. The overall schedule for each of the project is shown below. Note that one of the projects (Dallas Drive/Teasley Lane) is already under design and the surveying (first step of the design phase) for the remaining projects will begin January 29, 2018. CONCLUSION: Staff plans to move these small intersection improvement projects through the design and construction phase in an expeditious way to complete majority of the construction by end of 2018.
