600 East Fourth Street
Charlotte, NC 28202
Dear Mr. Richards:
You have our approval, in accordance with the attached conditions, to place fill material in 0.096 acres of
or waters for the purpose of improving a stream channel to alleviate flooding at Olde Savannah Road area, as
you described in your application dated September 26, 1997. After reviewing your application, we have
decided that this fill is covered by General Water Quality Certification Number 3108. This Certification allows
you to use Nationwide Permit Number 26 when it is issued by the Corps of Engineers. In addition, you
should get any other federal, state or local permits before you go ahead with your project including (but not
limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed
regulations. Also this approval will expire when the accompanying 404 or CAMA permit expires unless
otherwise specified in the General Certification. This 401 replaces the one issued on October 21, 1997.
This approval is only valid for the purpose and design that you described in your application. If you
change your project, you must notify us and you may be required to send us a new application. If total
wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed
in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are
final and binding unless you ask for a hearing.

Olde Savannah Road Storm Water Maintenance Improvement Project
Narrative
The City of Charlotte Storm Water Services Maintenance Repair Program investigates complaints
made by property owners who have suffered property damage or loss as a result of storm drainage
systems not functioning correctly. USInfrastructure (USI) is a consultant to the City and has
investigated complaints regarding the subject area. Storm Water Services received the first
complaint at 6914 Olde Savannah Road on 9/11/95. Since the initial date, at least five more
complaints have been filed by one or more property owners to report severe flood damage.
A summary of the problems along this area are as follows:
1. The existing channel and pipe system through the subject properties drains
approximately 100 acres. Two large ponds that were previously upstream have been
filled for commercial and residential development. Therefore, the existing channel
receives a substantial amount of storm water with very little attenuation provided
upstream. The existing channel dimensions ate inadequate.
2. The existing channel upstream of Olde Savannah Road has become silted in from
development upstream.
3. The existing culvert at 6914 Olde Savannah Road is a 42" RCP. The finished floor
elevation of the house at this address is lower than the road and lower than the top
of the existing 42" RCP.
4. The existing 42" RCP is significantly undersized with house flooding occurring
during the 10-year storm event. House flooding has occurred twice in the last 11
months.
5. The existing channel downstream of Olde Savannah Road has silted in and lost
definition. Storm water ponds in the rear and side yards of 6839 and 6845 Old
Savannah Road.
?i
6. The proposed culverts are extended 91 fe t upstream from the existing culvert end.
This extension is required to move tie 'inlet control condition to a point where it can
be controlled without flooding the house.
7. Bio-engineering_techniques for channel stabilization were considered but not selected
for the following reasons:
The existing channels pass through sideyards and backyards in close
proximity to existing homes. The higher Manning's n values of a
bioengineered solution vs. riprap channels would require larger channel
Page 2 of 2
sections and take away even more of the property owners' yards than the
current design. In addition, the "overgrown" appearance -of a mature
bioengineered channel may not be acceptable to the property owners.
• Proposed Channel C along the northeastern boundary of 6914 Olde Savannah
Road is a storm water channel (flows only during storm events) and drains
a small watershed. Therefore, it is not subject to any mitigation
requirements.
• The existing channel upstream of Olde Savannah Road is mostly grass-lined
with erosion and siltation present. It has minimal tree cover. Therefore, we
do not believe the channel will be adversely impacted by the proposed
improvements.
• No aquatic life has been observed within these channels during numerous site
visits.
• The additional design and specialized construction cost for bioengineered
channel stabilization do not seem warranted for this project because of its
rather limited scope and impact.
The property owner at 6914 Olde Savannah Road (upstream) has experienced three house flooding
events within the past two years. The proposed improvements were designed to eliminate the house,
street, and yard flooding that occurs with almost each heavy rainfall. The attached pictures were
taken after the significant rainfall event that occurred in Charlotte on July 23, 1997.

Dear Mr. Wilson:
On 25 August 1997 the Division of Water Quality (DWQ) was notified by receipt of
your application regarding your plan to fill wetlands for the purpose of conducting
streambank maintenance at Olde Savannah Road in Mecklenburg County. Approval from
DWQ is required to disturb these wetlands. The enclosed application needs to be
completed and returned to us with 7 copies of the application, supporting maps and
documentation. In particular as described in 15A NCAC 2B .0502, we will require you to
locate all streams and ponds on the property. Please show these on maps of suitable scale
(for instance 1 "=100 feet) so we can begin to determine your projects' compliance with
15A NCAC 2H.0500. Please specify the stream lengths and locations to be impacted.
Please call me at 919-733-1786 if you have any questions or would require copies of
our rules or procedural materials.

The property owner at 6914 Olde Savannah Road (upstream) has experienced three house flooding
events within the past two years. The proposed improvements were designed to eliminate the house,
street, and yard flooding that occurs with almost each heavy rainfall. The attached pictures were
taken after the significant rainfall event that occurred in Charlotte on July 23, 1997.
