City of Elk - Request for Action River O. To Item Number Mayor and City Council 9.1 Agenda Section Meeting Date Prepared by Work Session November 18, 2013 Justin Femrite, P.E. City Engineer Item Description Reviewed by 2014 Intersection Enhancement Projects Cal Portner, City Administrator Reviewed by Action Requested Provide staff direction on preferred options to 2014 intersection enhancement projects. Background/Discussion Included in the 2014 Capital Improvements Plan is a project for enhancements to existing intersections to improve safety and mobility. The three intersections currently being scoped for improvements are detailed below: Main Street and Parrish Avenue Intersection This intersection continues to generate a high number of complaints and concerns related to limited sight distance and overall congestion. In the past five years there have been a number of crashes and numerous reported close calls at this location. The issue of congestion is directly related to the proximity of this location to the Main Street and TH 10 intersection. Little improvement to congestion will be realized at the Main Street Parrish intersection without larger capacity improvements made at TH 10 and Main Street. Engineering staff has reviewed the sight line concerns and has evaluated 4 possible options to improve this safety concern: • Option 1 —Stripe no parking on south side of Main Street west of the intersection—Costs estimated to be less than $500. • Option 2—Add stop control for eastbound Main Street traffic—Costs estimated to be less than $1,000. • Option 3—Remove parking and add right turn lane for eastbound to southbound movements — Costs estimated to be around$15,000. • Option 4—Design and install a new mini roundabout in this location—Costs estimated to be about$150,000. Proctor Road and Highland Road Intersection Accident history at this intersection suggests modifications should be considered to increase awareness of the existing traffic control devises. The intersection is currently a two-way stop controlled intersection with stop signs facing east-west traffic on Highland Road and 194`''Avenue. Proctor Road movements are unrestricted. Staff is recommending supplementing the existing control in one of two ways: • Option 1 —Replace existing stop signs with LED flashing stop signs—Costs about$4,000. • Option 2—Add LED flashing`Approaching Traffic' signs—Costs of about$6,000.
