STAFF RECOMMENDATION: Staff recommends the Board of Supervisors (Board) direct staff to prepare a budget adjustment to amend the FY 2016 Capital Improvements Program (CIP) budget to appropriate $129, in cash proffers from ZMAP , Sequence Number , in the Public Facilities Fund and transfer that amount to the Capital Fund, and transfer $175,000 from the Traffic Signal Contingency Fund to fund the installation of a traffic signal at the intersection of Northstar Boulevard (Route 659) and Ryan Road (Route 772). BACKGROUND: The subject intersection is experience increased traffic congestion due to development along Northstar Boulevard and Ryan Road from the western edge of Brambleton to Shreveport Drive (Route 621) and Loudoun County Parkway (Route 607) (Attachment 1). The opening of Northstar Boulevard from its intersection with Ryan Road to Creighton Road (Route 774) has also contributed to an increase in traffic volumes passing through the subject intersection. Although Northstar Boulevard provides relief for Belmont Ridge Road, motorists are still experiencing excessive delays at the subject intersection. As part of the FY 2014 CIP budget, $230,000 in local gasoline tax funding was appropriated in the Capital Fund for the warrant study, design and construction of the traffic signal at Northstar and Ryan Road. The traffic signal warrant analysis for the referenced intersection was prepared and approved by the Virginia Department of Transportation (VDOT) on September 5, In July 2013, the
