US 64, From West of NC 281 at Lake Toxaway to Indian Creek
Transylvania County, TIP Protect R-2409C
11/29/07
Meeting Purpose
• The purpose of this meeting is to discuss revisions to R-2409C since the 10/10/06 interagency
meeting on this project NCDOT has revised the alternatives to avoid the small whorled
pogoma plant population and to reduce stream impacts
Protect Description and Purpose
An Environmental Assessment is underway for upgiadmg this 1 5-mile, two-lane portion of
US 64 near Lake Toxaway
US 64 has narrow lanes and shoulders, sharp curves, and a design speed that is lower than the
posted speed linut of 35 to 45 mph Slow moving trucks with trailers encroach into opposing
lanes of traffic while maneuvering through the sharp curves
The project proposes to correct roadway deficiencies, improve safety, and improve traffic
flow by straightening the roadway where possible, providing standard-width travel lanes and
shoulders, and adding a westbound climbing lane
Alternatives Studied in Detail
• Alternate 2 realigns portions of the roadway to provide flatter horizontal curves and achieves
a mimmum design speed of 30 mph This alternative has been revised to avoid impacting the
small whorled pogonia plant populations by following the existing roadway in the aiea of the
plants, keeping the current shoulder and cut slope in place on the north side Alternate 2 will
be studied in detail in the Environmental Assessment
• Alternate 4 corrects more of the alignment deficiencies, straightens curves, and increases the
design speed to 40 mph This alignment avoids the small-whorled pogonia plants by
following the existing roadway in the aiea of the plants It keeps the current shoulder and cut
slope in place and rejoins the Alternate 3 alignment west of the plant population This
alternate provides the highest level of improvement and will be carried forward in the project
study
Alternatives Eliminated from Further Consideration
• Alternate 1 follows the existing alignment without flattening any of the sharp horizontal
curves This alternative maintains a mimmum design speed of 20 mph This alternative was
eliminated from further consideration because it does not meet the purpose and need
Alternate 1 does not sufficiently address the roadway deficiencies since it does not improve
sharp curves in the alignment Although it includes wider lanes, a climbing lane, and paved
shoulders, trucks will continue to have difficulty remaining in the travel lanes in the sharp
curves Of the 38 horizontal curves in this alternate, 25 would need 10 feet or more of
additional pavement width to prevent trucks from encroaching into oncoming travel lanes
Some would require as much as 25 feet of additional width Alternate 1 would require high
costs for little benefit, and would be similar to the no-build condition
• Alternate 3 corrects more of the alignment deficiencies, straightens curves, and increases the
design speed to 40 mph This alignment passes behind the small-whorled pogoma plants, and
the plants would remain on high ground above the road beds on either side This is not a
desirable condition from the USFWS perspective and would not minimize the effect on the
plants For this reason, Alternate 3 was eliminated from further consideration
Small-whorled pogoma
• A Small-whorled pogonia population (8 plants) was identified in June 2006 It is located on
the north side of US 64 at the eastern end of the project, approximately 50 feet from the
existing road
• Alternatives 2 and 4 avoid the population by following the existing alignment in the area of
the plants
