o A full access should be at least 845 feet from Armstrong Boulevard and a right <br />in/right out access should be at least 470 feet from Armstrong Boulevard. <br />• Bunker Lake Boulevard (west of commercial section): Expand to a four lane section for <br />development (two westbound through lanes, one eastbound through lane and one <br />center left turn lane). <br />o Right turn lanes (locations and lengths) will be determined based on <br />development type. <br />o Outside westbound through lane drops to a right turn lane into the school <br />property. <br />• Puma Street: Expand to a three lane section for development (two through lanes and <br />one center left turn lane). <br />o Right turn lanes (locations and lengths) will be determined based on <br />development type. <br />• Bunker Lake Boulevard & Puma Street: An all -way stop, two-way stop, or roundabout <br />will operate adequately at this intersection for the 2040 Full -Build conditions. The <br />roundabout option may offer better operations than the other two options at 2040 <br />Full -Build. <br />Mid -Term Improvements <br />• Armstrong Boulevard & Alpine Drive: Add northbound and southbound left turn lanes. <br />Modify eastbound and westbound lanes to include a thru/left and a right turn lane. <br />Another option at this location includes construction of a multi -lane roundabout with <br />single lanes of approach on the eastbound, southbound, and westbound legs and two <br />lanes of approach on the northbound leg. The completion of an Intersection Control <br />Report (ICR) is recommended to determine the best intersection control at this <br />intersection. <br />• Alpine Drive & Puma Street: Add a westbound left turn lane and eastbound right turn <br />lane. <br />• Armstrong Boulevard & Bunker Lake Boulevard: Re -stripe southbound lanes to include <br />a dual southbound left turn lane. A southbound double left turn lane will help reduce <br />queues entering the COR development. Improvements were done in 2011 to this <br />intersection and a future southbound left turn lane was designed, but not striped. <br />Long -Term Improvements <br />• Armstrong Boulevard & Bunker Lake Boulevard: Modify the southerly eastbound <br />through lane to a through -right lane. Another option would be to keep the two through <br />lanes and modify the right turn lane into a free right with an add lane that runs south <br />to T.H. 10, or potentially add an additional right turn lane. <br />Prepared by: Bolton & Menk, Inc.
