Subject: Villages at Reedy Fork Subdivision — Permit modification request
USACE Action ID No. SAW- 2003 -20436
(DWR # 03 -0056 v3)
Dear David:
On behalf of AF -Reedy Fork LLC (owners of this project) we would like to request a
modification to the above reference permit for two separate temporary stream impacts
due to the proposed installation of a public sanitary sewer outfall.
Temporary Impacts:
To install the sanitary sewer outfall a temporary stream impact of 40 LF per stream
crossing will occur. All portions of the outfall are to be placed permanently below grade
with no permanent impact on the stream. Construction of these temporary stream
impacts are to be constructed per City of Greensboro standard detail number 213
(attached to this letter). Once the sanitary sewer line is installed, rip rap is to be
depressed into stream bed until the top of rip rap is level with stream bottom
(construction sequence and detail provided).
Factors Preventinz Implementation of Practical Alternatives:
Waste water generated from this project is required by the city ordinance to tie into a
public sanitary sewer system, eliminating on -site treatment as a practical alternative for
future development. Due to the topography of this project, this outfall is needed to
provide sanitary sewer to multiple future phases of The Villages of Reedy Fork Ranch
that at this time have no connection point to public sanitary sewer. The use of a public
pump station and force main are highly discouraged by the city when gravity sewer is
available. The only other alternative to not cross the streams at these two locations would
be to run the outfall on the western side of the stream (tributary to Reedy Fork creek)
which would in turn require multiple stream crossings of a much larger stream.

NOTES.'
1) EROSION STONE TO BE "CLASS I" RIP -RAP UNLESS DESIGNATED DIFFERENTLY ON
CONSTRUCTION PLAN.
2) PIPE SIZE AND AMOUNT NEEDED TO BE DETERMINED BY ENGINEER ON CONSTRUCTION
PLAN.
3) TEMPORARY STREAM CROSSING TO BE CONVERTED TO COG #214 UPON PROJECT
CONSTRUCTION COMPLETION IF CALLED FOR ON THE CONSTRUCTION PLANS.
4) PUMP AND LINE SIZE TO BE DETERMINED BY THE CONTRACTOR USING THE BASE FLOW
SHOWN ON THE CONSTRUCTION PLANS.
5) WIDTH OF CONSTRUCTION EASEMENT SHALL BE MINIMIZED BASED UPON FIELD CONDITIONS.
ANY DISTURBANCE (S) EXCEEDING 40' MAY REQUIRE ADDITIONAL WATER DUALITY PERMITTING
OR MI TIGA TION.
CONSTRUCTION SEQUENCE FOR STREAM CROSSING
1) INSTALL PUMP AND LINE TO PUMP FLOW FROM AREA UPSTREAM OF TEMPORARY STREAM
CROSSING TO AREA DOWNSTREAM OF CONSTRUCTION AREA. BEGIN PUMPING AND
CONTINUING PUMPING WHILE WORKING WITHIN THE STREAM
2) INSTALL UPSTREAM DAM, FIL TER FABRIC. AND TEMPORARY CMP. COVER PIPE INLET
WITH FABRIC AND SAND BAGS AS SHOWN IN INSET "A " WHILE WORKING IN THE STREAM.
ALLOW STREAM FLOW THROUGH CMP AS SHOWN IN INSET "B" WHEN NOT WORKING WITHIN
THE STREAM.
3) INSTALL DOWNSTREAM TEMPORARY STONE DAM AND FIL TER FABRIC TO PREVENT
BACK FLOW INTO CONSTRUCTION AREA.
4) INSTALL PROPOSED EARTH BERMS ALONG TOP OF BANK ON EACH SIDE OF THE
CONSTRUCTION AREA.
5) INSTALL DEWA TERING BASIN OR SIL T BAG A T TOP OF BANK. DEWA TER CONSTRUCTION
AREA BETWEEN TEMPORARY DAM USING THIS BASIN.
6) INSTALL THE 10' X 10' SEDIMENT TRAP OR SILT BAG.
7) UPON CONSTRUCTION COMPLETION, REMOVE TEMPORARY DAMS, FILTER FABRIC, AND
TEMPORARY CMP. DEPRESS TEMPORARY DAM BOTTOMS INTO STREAM BED UNTIL TOP OF
RIP RAP IS LEVEL WITH STREAM BOTTOM. CONVERT TO COG STANDARD 0214 IF CALLED
FOR IN THE CONSTRUCTION PLANS.
B) UPON STABILIZATION OF CLEARED AREAS, REMOVE TEMPORARY EARTH BERM, SEDIMENT
TRAP, AND DEWA TERING BASIN.
