at meeting of the Oregon Association of County Engineers and Surveyors in Hood
River, Oregon on October 24, 2002. The speaker from the city of Portland
reviewed the guidelines proposed at the present time.
One area of concern was the requirement for an elevator for greater vertical
changes over 60 inches. The rules treat urban and rural areas the same.
Therefore, a bikeway constructed along a river with an overpass across the river
would require an elevator. A couple of our current bikeways are located 5 miles
from town. Requiring elevators at these locations will make these projects cost
On the issue of protruding objects, could signs be off-set so they don't exceed
4 inches on the walkpath side, but exceed the 4 inch rule on the street side?
We have numerous streets that have a grade of 8 to 12 percent. Constructing
cross walks with a 2 percent cross slope will require the intersection grade to
be fairly flat. Tjis will require steeper grades coming in and going out of the
intersections. This type of construction would greatly increase costs. Will
there be some means for cost/benefit factors to be reviewed or is this retrictly
a court review?
Thanks for the opportunity to comment.
