TO: MAYOR AND CITY COUNCIL FROM: WILLIAM A. SIMMONS, CITY MANAGER DATE: October 11, 2005 SUBJECT: Update -SH42 Traffic and Access Study from Paschal Drive to 96th Street ORIGINATING DEPARTMENT: Public Works Department SUMMARY: Earlier this year the City retained Carter Burgess to conduct a Traffic and Access Study on State Highway 42 (SH42). The purpose of the study is to examine future capacity needs for SH42 and based on those needs the right-of--way required for future laneage. The work included a review of traffic impacts on South Boulder Road at the BNSF rail crossing in order to understand whether future commuter rail activities will have such an impact that the footprint for the SH42/South Boulder Road intersection would be impacted. The work also includes an analysis to see if a traffic signal could be installed at Short Street to accommodate future traffic at the commuter rail station. The Short Street signal would replace the one currently planned at Griffith Street. This would require relocation of the ball field complex's main access to coincide with the Short Street intersection. Future roadway improvements will require additional right-of--way. Existing right-of--way has been identified and future right-of--way needs established based on alternative alignments. An arterial view of the corridor showing existing and future right-of--way is attached. At Tuesday night's work session David Woolfall of Carter Burgess will present findings for an alignment that will utilize additional right- of-way on both the east and west side: of SH42. Council's comments will be incorporated into the second Public Open House scheduled for October 27. Staff will be using the findings of the report to guide future right-of--way acquisition as redevelopment activities occur. Additionally, a modified access plan will be pursued with Boulder County, the City of Lafayette and CDOT to identify the type; and location of future access points to Highway 42. .
