STATEWIDE PLANNING GOAL 10: To provide for the housing needs of citizens of the state. The TAMP project forecasted future 2042 traffic volumes to understand the extent of traffic congestion at the interchange ramps and intersections in the vicinity (TAMP Chapter 3). Anticipated growth in housing and employment in the Cities of Donald and Aurora factored into this future forecasting. Improvements at the interchange will ensure that transportation needs are balanced with the demands of future residential growth in the region. An RV resort business/residential community is located adjacent to the northbound off- ramp. The Aurora Acres RV Park has approximately 130 RV spaces. A majority of the occupants are permanent residents; many residents/families have lived there for several years. Proposed improvements will not result in any residential displacement. Goal 10 is met. STATEWIDE PLANNING GOAL 11: To plan and develop a timely, orderly and efficient arrangement of public facilities and services to serve as a framework for urban and rural development. The TAMP will amend the RTSP to add planned improvements at the interchange, including realignment (Ehlen Road, Bents Road, Dolores Way) and expansion (Ehlen Road) of County roadways, to meet the needs of planned rural development. The TAMP establishes special access management requirements for the interchange area to improve safety and help ensure traffic mobility is maintained (TAMP Section 5.5). The TAMP also establishes a mobility standard for the interchange that ensures capacity is preserved to serve the needs of future regional traffic (TAMP Section 5.6). These measures provide a basis for ensuring investment in public facility infrastructure is made in a manner that will accommodate the region's planned population and employment. STATEWIDE PLANNING GOAL 12: To provide and encourage a safe, convenient and economic transportation system. OREGON ADMINISTRATIVE RULE(OAR) 660-0012: The Transportation Planning Rule (TPR), Oregon Administrative Rule 660, Division 12, defines how to implement Statewide Planning Goal 12 and outlines the necessary elements of a local Transportation System Plan (TSP). The overall purpose of the TPR is to provide and encourage a safe, convenient, and economic transportation system. The TPR directs TSPs to integrate comprehensive land use planning with transportation needs and to promote multi-modal systems that make it more convenient for people to walk, bicycle, use transit and drive less. The requested action includes modifications to the local roadway system, a required element of the County's TSP. The adoption of TAMP improvements will ensure that the interchange operates safely and efficiently in the future. TAMP Chapter 3 describes the transportation analysis that was conducted in order to determine existing and future safety issues, future demand, capacity, deficiencies, and needs for this interchange area. The analysis demonstrates that the recommended Preferred Alternative will adequately serve trips generated by future planned land uses.
