In addition, the Borough may require any street
that does not have curbs to include appropriate four-foot-wide shoulders
on each side of the cartway constructed to Borough standards. As an
alternative to paved or stoned shoulders along local residential streets,
the Borough may, at its option, permit stabilized shoulders.
|
NOTES:
| ||
---|---|---|
1
|
Horizontal sight distances shall be measured
from a point 3.5 feet above the road surface to a point six inches
above the road surface, and shall be based upon standards of the American
Association of State Highway and Transportation Officials (AASHTO).
| |
2
|
All tangents shall be measured along the street
center line.
| |
3
|
Larger radii may be required as determined to
be needed by the Borough Engineer or PennDOT.
| |
4
|
Minimum grades for all streets shall be 1.0%,
unless the Borough Engineer determines that a lesser grade is acceptable.
| |
5
|
Borough Council shall determine the appropriate
width within the ranges provided in this table, unless an official
modification or waiver is granted to these standards.
