Brotzler, PE, City Engineer AGENDA NO. 6j,( ATTACHMENTS: Preliminary Layout; Cost Estimate; Resolution APPROVED BY: /y 7J RECOMMENDED ACTION: Motion to Adopt a Resolution Ordering Plans and Specifications for 42 /Shannon Parkway Intersection Improvements, City Project #412. �C ROSEMOUNT CITY COUNCIL City Council Meeting: January 16, 2007 EXECUTIVE SUMMARY BACKGROUND: In 2006, Council discussed on several occasions the CSAH 42 /Shannon Parkway intersection and issues at this intersection. The two issues at this intersection are 1) the offset m the driving lanes on Shannon Parkway that creates a challenge for left turning and through traffic, and 2) the cross section of CSAH 42 when traveling north and south on Shannon Parkway. As an interim measure to address the cross section of CSAH 42, "Slow Bump Ahead" advisory signs were installed on northbound and southbound Shannon Parkway. In addition, Council authorized the preparation of preliminary plans to evaluate permanent solutions to the above two issues and to develop a cost estimate for the necessary improvements. At this time, a preliminary layout has been developed for the intersection and is attached. As shown on the attached layout, the following improvements are proposed: Add raised concrete median and widen Shannon Parkway north of CSAH 42. Mill and overlay CSAH 42 and modify the raised concrete medians on CSAH 42 to flatten the profile on Shannon Parkway through the intersection of CSAH 42. Install new signal system with protective /permissive left tum phasing for Shannon Parkway, similar to the recent revisions to the signal system at CSAH 42 and Chippendale Avenue This proposal will need to be approved by Dakota County. A cost estimate and proposed funding split with Dakota County has also been developed and is attached. Dakota County staff has indicated that the County has funding available for this project m 2007 and will begin the preparation of a joint powers agreement upon City authonzanon. The City's share of the estimated project costs is ehgible for municipal state aid CMSA) funds. Due to past MSA funding commitments for the TH 3 /Connemara Trail /McAndrews Road Signal System project and the Connemara Trail Overpass project, for the project to move forward in 2007, Street CIP Reserve Funds would need to be used to upfront the cost. As MSA funds become available m 2008, those future funds can be collected for this project.
