In response to your request on June 20, 2008 for additional information regarding the
traffic circulation pattern for the TT&E Facility Expansion that requires three lanes of
traffic at the crossing going in the same direction.
The TT&E facility is open to the general public for the delivery and drop-off of
household and construction metal waste for recycling. Vehicles arrive at the site and are
stacked in lanes prior to accessing the gated area. When entering the gate the vehicles are
weighed and then proceed as directed to various stockpiles for unloading. The vehicles
then return to the scale and gate and are re-weighed before receiving payment for their
metal. See attached sketch that shows circulation pattern.
When the site was submitted to the Town of Garner for site plan approval of the proposed
expansion, one of the primary concerns was appropriate internal stacking of the arriving
vehicles to limit or reduce the stacking of vehicles on Old Garner Road. The current site,
which is all contained on the eastern side of the stream, has one entrance and at peak
operating hour's traffic backs up on the public road creating safety concerns.
A traffic Study was conducted by Ramey Kemp and the peak queuing distance indicated
was 2,008 linear feet with a 25% increase in business.
The existing facility has peak vehicle queuing demand of approximately 2,000 feet
during the Saturday morning peak period (the facility's busiest time of the week). This
queue is partially accommodated by existing on-site storage. The remainder of the queue
extends from the existing site driveway back into Garner Road on the southbound
approach and partially blocks Garner Road for a few hours during the Saturday morning
peak period. Existing on-site storage is inadequate to handle stacking demand. The
NCDOT review of the first proposed site plan without the addition of the new parcel to
the north of the existing property indicated that inadequate on-site storage was a concern.

With the recent acquisition of the new parcel where the shredder equipment will be
situated, the queue can be entirely accommodated on-site.
Integrating the existing site with the newly acquired parcel requires a reworking of the
internal traffic flow. To accommodate the queuing vehicles, the stream buffer must be
crossed by the roadway where vehicles will be waiting to be weighed in at the scales and
enter the processing area of the facility. Without the addition of the new parcel, the
existing queue of 2,000 feet can not be accommodated on-site and would continue to
extend into Garner Road and block traffic for a period during Saturday morning. With
the addition of the new parcel, a total vehicle queue in excess of 2,600 feet can be
accommodated on-site without blockage of Garner Road.
The Town of Garner, in its review of the first site plan (without the new parcel), indicated
that inadequate on-site stacking was provided. The adjacent parcel was acquired and the
site plan was reworked to improve the site layout and internal circulation. The issue of
providing on-site stacking was raised by members of the Garner Planning Commission in
May as well by members of the Garner Board of Aldermen in June. The provision of
adequate on-site stacking was a key component to the approval of this site, since it serves
as a huge improvement over existing conditions with vehicles queuing into Garner Road
during peak periods, as well as provides excess storage capacity to handle the potential
for a growth in the facility's business and increased need for vehicular stacking in the
future.
Without the crossing over the stream buffer, adequate on-site stacking can not be
provided."
The owners of the site have purchased the adjoining parcel (west side of creek) for the
location of the proposed shredder and to allow an internal access drive that can provide
the required stacking as indicated by the traffic study. This access drive will need to
cross the stream and will impact 138 if of the stream.
The circulation pattern proposed is a two lane drive entering the site to the extreme west.
All traffic would enter at this point. NCDOT road widening and Town of Garner
required curb and gutter will be provided. Traffic will then proceed to the existing site,
crossing the stream. All public traffic will then enter at the gate to the weighing scale at
the existing gate. From there the public can off-load their items either at various
stockpiles on the existing site or re-cross the stream to the new site and off-load at the
shredder. They then would re-cross the stream to exit at the scale, park and get paid for
their metal based on the difference between the arriving weight and exiting weight. All
off-loading and shredder operations must take place within the security fencing
surrounding the site. The stream must be crossed both outside the fence for in-coming
traffic and crossed with two way traffic within the fenced area for movement between the
two sides of the facility.

We have tried to keep the lanes as narrow as possible and are trying to minimize the
overall disturbance to the stream.
Thank you for your consideration of our request for the stream crossing.
Sincerely,
Kathryn McPherson, R.L.A.

THE TT&E SITE IS CURRENTLY ALL LOCATED ON THE SOUTHERN SIDE OF THE CREEK THERE IS '
INADEQUATE STACKING ON THIS SITE CURRENTLY ALL TRAFFIC ENTERS AND EXITS AT THE PUBLIC
EXIT LOCATION DURING PEAK OPERATION HOURS TRAFFIC BACKS UP IN THE TURN LANE ON WEST
GARNER ROAD AND CREATES TRAFFIC HAZARDS AT THE OPPOSING DRIVEWAYS THE TOWN OF
GARNER AND NCOOT BOTH WANTED THE STACKING TO BE PROVIDED FOR WITHIN THE SITE THE
TRAFFIC STUDY SHOWED A PEAK QUEUE OF 2.006 LF REQUIRED WITH 25% FOR GROWTH WE HAVE
PROVIDED A NEW ENTRANCE THAT WILL ALLOW ADEQUATE STACKING TO OCCUR COMPLETELY
WITHIN THE SITE ALL PUBLIC TRAFFIC WILL QUEUE ALONG THE FRONT DRIVE (OUTSIDE THE FENCED
OPERATIONS AREA( VEHICLES WILL THEN ENTER THE OPERATIONS AREA AND ARE YVEIGHED THE
CUSTOMER WILL THEN BE ABLE TO OFF-LOAD THEIR RECYCLEABLE MATERIAL EITHER AT STOCKPILES
ON THE SOUTHERN PORTION iEXISTING SITE) OR TRAVEL (WITHIN THE SECURITY FENCE) TO THE
SHREDDER SIDE FOR OFF-LOADING THE VEHICLES ARE THEN REQUIRED TO GO BACK TO THE
SCALE AT THE GATE TO BE RE-WEIGHED TO DETERMINE THE FEE THEY THEN COLLECT AT THE OFFICE
ALL TRAFFICE THEN EXITS THE SITE AT THE PUBLIC EXIT IT IS NECESSARYAT THE STREAM CROSSING
TO PROVIDE TWO LANES OF TRAFFIC OUTSIDE THE FENCE (FOR QUEUING) AND 2 LANES INSIDE THE FENCE
