Dear Mr. Alsmeyer and Ms. Higgins:
Subject: UT to Falls Lake - Ward Property Stream Restoration Project
401/404 Pre -Construction Notification Application
CEC Project 144-040
Enclosed for your consideration and approval is the Pre -Construction Notification for the US Army
Corps Nationwide Permit 27 and the Division of Water Quality's General Certification 3885 for
stream restoration and stabilization for the UT to Falls Lake - Ward Property Stream Restoration
Project. This project is located on Mr. Ward's property off Hamlin Road in Durham County.
Please note that we have requested the application be reviewed before mid-July 2017 to enable site
preparation to take place so that the riparian buffer may be planted during the appropriate dormant
season at the end of this year. Thank you in advance for your assistance.
This project meets the DWQ definition of stream restoration and funding was provided by
grant funding client. A permitting fee has been included with this package. This is not a
stream mitigation project.
If I can be of any further assistance, please contact me at [phone].

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The existing stream channels are so incised and degraded that a new channel is being
designed in order to stabilize and restore stream function to this section of channel. The new
channel will have an opportunity to function with a floodplain again and help with nutrient
removal.
Sediment and Erosion control measures will be designed in order to keep sediment onsite and
to temp. stabilize the site.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Sediment and Erosion control measures will be used in order to minimize the impact on the
stream ecosystem. Such measures will be rock dams, coir fiber matting, silt fence, wood mat
crossings, pump -around, geolifts, and working offline.

CONSTRUCTION SEQUENCE
A CEC PROJECT MANAGER WILL PROVIDE CONSTRUCTION QUALITY ASSURANCE DURING THE
CONSTRUCTION PHASE OF THIS PROJECT. THE FOLLOWING CONSTRUCTION SEQUENCE SHALL
BE USED DURING IMPLEMENTATION OF THE PLAN.
1. PRIOR TO BEGINNING ANY LAND DISTURBING ACTIVITIES, NOTIFICATION AND APPROVAL MUST
BE GRANTED FROM US ARMY CORP OF ENGINEERS AND NCDWR DIVISION OF WATER
QUALITY.
2. THE CONTRACTOR SHALL CONTACT NORTH CAROLINA 811 CENTER (1.800.632.4949) AND
LAND QUALITY (919.791.4200) BEFORE ANY EXCAVATION.
3. THE CONTRACTOR WILL MOBILIZE EQUIPMENT AND MATERIALS TO THE SITE BY INSTALLING
AND USING THE CONSTRUCTION ENTRANCE (THAT ARE SHOWN ON THE PLANS) OFF HAMLIN
AND MORTON ROADS.
4. THE CONTRACTOR WILL UTILIZE THE HAUL ROADS AND STREAM CROSSING AS SHOWN ON
THE PLANS. CONSTRUCTION TRAFFIC SHALL BE RESTRICTED TO THE AREA DENOTED AS
'UMITS OF DISTURBANCE'ON THE CONSTRUCTION PLANS.
5. THE CONTRACTOR SHALL INSTALL TEMPORARY SILT FENCE AROUND THE STAGING AREAS.
THE CONTRACTOR WILL NOT PLACE EXCAVATED FILL INTO THE OLD CHANNEL UNTIL THE
NEW CHANNEL IS COMPLETE AND WATER HAS BEEN DIVERTED INTO THE NEW CHANNEL.
6. THE CONTRACTOR SHALL INSTALL ALL TEMPORARY STREAM CROSSINGS AS SHOWN ON
PLANS IN ACCORDANCE WITH THE NC EROSION AND SEDIMENT CONTROL PLANNING AND
DESIGN MANUAL. DITCHES AND STREAM REACHES ON SITE WILL BE LEFT OPEN DURING
THE INITIAL STAGES OF CONSTRUCTION TO ALLOW FOR DRAINAGE AND TO KEEP SITE
ACCESSIBLE.
7. CONTRACTOR SHALL BEGIN CONSTRUCTION ON EACH STREAM REACH AND COMPLETE THAT
SPECIFIC STREAM REACH BEFORE MOVING TO THE NEXT REACH. THE NEW CHANNEL
SECTIONS SHALL BE LEFT OPEN ON THE DOWNSTREAM END TO ALLOW FOR DRAINAGE
DURING RAIN EVENTS. AT NO TIME WILL CLEARING AND GRUBBING PROGRESS BEYOND
THE SECTION OF CHANNEL THAT IS BEING CUT UNLESS WORKING WITH MORE THAN ONE
CREW (I.E. CANNOT REMOVE TREES ON BETWEEN STATIONS 14+22 TO 16+00 WHEN YOU
ARE WORKING BETWEEN STATIONS 10+00 TO 14+00 ALONG THE MAIN STEM).
8. MAJORITY OF THE PROJECT IS ONLINE CONSTRUCTION, CONTRACTOR WILL INSTALL TYPICAL
PUMP AROUND OPERATION WHEN SUFFICIENT FLOW IS PRESENT.
MAINSTEM OF UT TO FALLS LAKE (Ml M2 M3) & TRIBS (UTI UT2 UTZ) CONSTRUCTION
9. ONCE STAGING AND TEMPORARY E ORARY CROSSINGS ARE COMPLETE, THE CONTRACTOR WILL START
WITH UT2. UT2 IS AN EPHEMERAL CHANNEL AND TYPICALLY DOESN'T FLOW. IF
SUFFICIENT FLOW IS PRESENT, THEN A PUMP -AROUND IS NEEDED (SEE /22 AND #23
FOR PUMP -AROUND INSTRUCTIONS).
10. ONCE THE SECTIONS OF UTZ HAVE BEEN EXCAVATED TO DESIGN GRADES, INSTALL
IN -STREAM STRUCTURES, INSTALL 10' CHANNEL PLUGS (STATION 11+00 AND 11+35),
SEED AND MAT, AND READY THE CHANNEL TO ACCEPT FLOW. ONE REACH SHOULD BE
COMPLETE WITH ALL STRUCTURES, SEED, AND MATTING BEFORE MOVING ONTO THE NEXT
REACH.
11. THE CONTRACTOR WILL MOVE TO LITT WHEN UT2 IS COMPLETE. UTI IS ALSO AN
EPHEMERAL CHANNEL AND TYPICALLY DOESN'T FLOW. IF SUFFICIENT FLOW IS PRESENT,
THEN A PUMP -AROUND IS- NEEDED (_SEE #22 AND #23 FOR PUMP -AROUND
INSTRUCTIONS).
12. ONCE THE SECTIONS OF UT1 HAVE BEEN EXCAVATED TO DESIGN GRADES, INSTALL
IN -STREAM STRUCTURES, INSTALL 10' CHANNEL PLUGS (STATION 12+15 AND 12+50),
SEED AND MAT, AND READY THE CHANNEL TO ACCEPT FLOW. ONE REACH SHOULD BE
COMPLETE WITH ALL STRUCTURES, SEED, AND MATTING BEFORE MOVING ONTO THE NEXT
REACH.
13. THE CONTRACTOR WILL MOVE TO M1 WHEN LITT IS COMPLETE. M1 IS ALSO AN
