Explanation
1. BACKGROUND
The City of Columbus ("Columbus") and the City of Dublin ("Dublin") have identified the need for widening and improving Emerald Parkway from Rings Road to Tuttle Crossing Boulevard. 60% of this project is in the City of Columbus. The City of Dublin has been the lead agency during the design phase of this project. Initially a new traffic signal was to be constructed at the intersection of Lakehurst Coutrt and Emerald Parkway; however, value engineering determined that a roundabout would provide better access at a lower cost than the proposed traffic signal. The value engineering process also determined that by widening the south leg of the intersection of Emerald Parkway and Tuttle Crossing (Britton parkway, name changes south of Tuttle Crossing) by approximately 5 feet, the intersection could be re-aligned which would improve the level of service and operation of the signal. Columbus met with Dublin to discuss these issues and Dublin concurred with the conclusion reached by Columbus. Dublin is also changing their design from a proposed traffic signal at Glendon Court to a roundabout.
The improvements contemplated by this project shall include widening Emerald Parkway to 5 lanes at intersections with 4 lanes and a median between intersections, curb and gutter, sidewalks, shared use paths, roundabout at Lakehurst Court, street lighting, regulatory road signage, pavement markings, storm drainage, utility relocation, and landscaping, all in compliance with the Americans with Disabilities Act (A.D.A.) criteria. The south leg of the intersection of Emerald Parkway (Britton Parkway) at Tuttle Crossing will be widened for approximately 200' south of Tuttle Crossing Blvd to allow for better alignment and improved level of service at this signal.
This project complies with the recommendation of the Pedestrian Thoroughfare Plan by maximizing sidewalk width and lateral separation from traffic within the constraints of the right-of-way limit...
