Dewberry Project No. 5oo62103
Dear Ms. Higgins:
Enclosed are five copies of a Pre - Construction Notification (PCN) Permit Application Package for the City
of Durham TW Alexander Drive Emergency Sanitary Sewer Repair and Access Road project. For your
review we have enclosed five copies of the PCN Application Form, Attachment A — Additional
Information, USGS Quadrangle Map, site photos, site plan schematic, and the $240.00 application fee.
The project titled "Emergency Sanitary Sewer Repair and Access Road" consisted of construction of a
gravel access road within the Jordan Lake Riparian Buffer to facilitate the emergency repair and
maintenance of a sanitary sewer line and manholes that had experienced failure. Since the construction
occurred in response to a sanitary sewer infrastructure failure, this PCN is being submitted after - the -fact.
The construction described in this permit application resulted in approximately 1,200 square feet of Zone
1, and 2,700 square feet of buffer impacts within a maintained utility easement.
Please contact me with any questions regarding this permit application.
Sincerely,
Dewberry Engineers Inc.

Attachment A - Additional Information
3.3 d Explain the, purpose of the proposed project
A sanitary sewer manhole collapse required immediate emergency repair Saturated soils prevented access
by construction vehicles so a gravel access road was constructed to facilitate access to,the'sewer line for
maintenance and repairs
3 3 e Detailed project description including equipment to be used
During routine inspection, it was discovered that two sanitary sewer manholes had collapsed along an outfall
near TW Alexander Drive m,Durham, NC City of Durham Water Management,personnel performed an
emergency repair by rising and repairing the two manholes Frequent flooding and standing water at the)site
rendered the site - inaccessible by construction vehicles To allow access for this and future maintenance,and
repair activities, a gravel access road was constructed to the farthest collapsed manhole
Conventional construction equipment (hydraulic excavators and dump trucks) °was�used to complete this
repair project Clean gravel was brought in to,construct the access road, which is 15 ft wide and
approximately 600 feet long A culvert was installed underneath the access road to promote water flow to the
river during flooding events Silt fencing,was installed at the top of the stream bank within the project area
prior to beginning work to prevent sedimentation into the river Silt fencing will be removed once vegetative
cover has been established
A sanitary sewer pump around was established to drain the manholes and sewer lines in the immediate
vicinity during the repair work Upon completion of the repair, all disturbed areas were seeded and-mulched
D.1.a Specifically describe measures taken to avoid or minimize the,proposed;impacts in designing
project.
To protect the sanitary sewer line and manholes from further impacts, the manholes were °raised and re-
grouted The access road was constructed within an existing easement and was kept to the minimum width
necessary for vehicles to gain entry to make the sewer repair A culvert wa "s <ffistalled under the roadway to
minimize impacts to water flow durmg,flood events Silt fencing was installed at the top oftheistream bank to
prevent sedimentation runoff and was maintained for the duration of construction When construction was
completed, the disturbed areas were mulched and seeded to restore vegetative cover The silt fencing will not
be, removed until 95% of the cover is restored
,D.1 b Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
Conventional construction equipment (hydraulic excavators and dump trucks) was used to complete this
repair project Clean gravel was brought on -site and used to construct,the access road A sewer pump around
wasi established to,dram the sewer'lmeAurmg construction A,tanker trunk'was on- hand,to pump, store, and
transport wastewater to the City's wastewater treatment plant for treatment Upon completion of the work,
disturbed sloped areas were stabilized and reseeded
