The proposed transportation system meets the requirements of Oregon's Transportation Planning Rule (TPR) and addresses the needs and concerns of those who live in the study area and use the system. This TSP considers all modes of transportation: motor vehicles, bicycles, pedestrians, air, rail, water and pipeline. A detailed roadway invento of the TSP study. indicated that many streets i onia have inadequate pavement width required functions. need of widening in several locations, the City's collectors. The pavement condition of most of the City's arterials and collectors is fair or worse. Local roads are also in need of improvements, with many segments in need of paving. Recommendations are made to bring these roads up to acceptable standards. The review of existing conditions also revealed several safety concerns. Many of these stem from high speeds and lack of sight distance or poorly designed intersections. Some hazards can be removed with modest, low cost projects; others require more detailed solutions. A level-of-service (LOS) analysis was conducted to determine existing traffic conditions at 10 key intersections. All were found to currently operate at acceptable levels of senrice; no intersection experiences an average stopped delay longer than 10 seconds. The TSP also addresses the lack of connectivity across the City. The state highway is the main connector for the whole City. Collectors and local streets that tie into Highway 47 do not provide a complete grid. Much of this lack of connectivity is due to the topographical features of the City. Bodies of water, hills and bluffs inhibit connections between some streets. Most of the connections that were evaluated were cost prohibitive, but it is recommended that Louisiana be developed to provide another north-south connection and that Clatsop
