US 101: Camp Rilea to Surf Pines Lane Facility Plan
Overview of Presentation
Project overview
Practical design considerations
Alternate mobility standards
NEPA compliance
Study Area
4.6 mile section of US101
South of Warrenton, north of Gearhart
Project limits: Camp Rilea (Patriot Way) to Surf Pines Lane
Mostly a 2-lane section
4 lanes north and south of study area
Issues
Above average crash rate—50% involve turns
No median—Steep shoulders—Driveways
Inadequate sight distance in some locations
Excessive speed is not a factor—55 mph limit
Congestion from turns and seasonal traffic
Impatient motorists taking risks
Practical design considerations
Constructing 5-lanes is too expensive ($45M)
Full 3-lane is also too expensive ($31M)20-year funding assumption to establish
performance expectations: $15
Recommend improving north segment to 3-lanes plus lower-cost spot improvements in rest of corridor
Features
Raised medians to limit turning movements
U-turns and J-turns
Combining and improving intersections
Geometric improvements
Widening shoulders
Mobility standards, NEPA considerations
Can’t meet mobility targets at intersections
Establish alternate mobility standards by altering acceptable V/C or altering analysis methodology to exclude seasonal peaks
Need to show that spot improvements have “independent utility” for Categorical Exclusion
3-lane improvement must be evaluated through a single NEPA process (either EA or EIS)
