example would be if traffic queuing at an intersection would block the driveway during the peak hour of the design life of the project, staff may require the driveway to be located farther away from the intersection. As covered in findings under Statewide Planning Goal 12 and ODOT's Division 51, ODOT access spacing standards apply in the vicinity of the interchange. The Preferred Alternative relocates Bents Road and Dolores Way intersections approximately 800 feet from the interchange ramp intersections, an action that moves towards meeting the access management spacing standard, improves current conditions, and complies with Division 51. ODOT also intends to purchase access rights along existing and relocated Ehlen Road, between relocated Bents Road and relocated Dolores Way, effectively ensuring that no new accesses would be allowed on this segment of Ehlen Road. These Policies have been met. 10.3.1 Transportation System Planning Policies Policy 1: The general priorities for Marion County, with regard to the County Road System, are in order of importance: 1) Preservation and maintenance of the existing road system. 2)Safety improvements and enhancements. 3) Capacity enhancements and growth-related projects. Policy 2: The County will evaluate all investments in the transportation system for cost- effectiveness,fiscal responsibility, economic efficiencies, and practicality. The County's transportation investment priorities mirror the State's objectives, as articulated in the Oregon Highway Plan Policy 1G, where the focus is on preservation of the existing system and safety improvements over adding capacity. The stated goal of the TAMP and reconstruction project is to improve safety, operations, and capacity problems while maintaining efficient movement of passenger and freight traffic through the interchange area with a phased solution that will accommodate the Phase 1 funding provided in the Keep Oregon Moving Act. Phase 1 improvements are focused on addressing the immediate safety issues, including the lengthening, widening, and signalizing of the northbound and southbound off-ramps and realigning Bents Road to align with Bents Court at existing Ehlen Road. These Policies have been met. Policy 5: Levels-of-Service considered acceptable in rural areas include: 1) LOS D or better with a volume/capacity ratio (v/c) of 0.85 or better for signalized, all-way stop, and roundabout intersections. 2) LOSE or better with a volume/capacity ratio (v/c)of 0.90 or better for other unsignalized intersections. 3) LOS D or better with a volume/capacity ratio (v/c)of 0.60 or better for road segments. 1-5:Aurora Donald Interchange(Exit 278)TAMP:Supporting Findings for Marion County Adoption 23
