REQUEST FOR MORE INFORMATION
Dear Cyndi:

On behalf of J. Chris Callaway, Asst. Vice President and Director of Design and Real Estate for
Wal-Mart Stores East, LP, Stocks Engineering is responding to your letter dated February 2,
2007 in which you request additional information for the above referenced project. Enclosed,
you will find 5 copies of the following:
• Qualitative Indirect and Cumulative Analysis for the project;
• Details and design calculations associated with changing bioretention cell no. 8 to
constructed wetland no. 2.
Thank you for your consideration of this project and we look forward to working with you.
Sincerely,
S~to~cks Engineering, P.A. (~/]

Qualitative Indirect and Cumulative Impact Analysis
for
Wal-Mart Supercenter #4459-00
Ut to Stony Creek [030302, 28-68, C, NSW]
The study area boundary for this analysis will consist of approximately 60 acres of land
as shown on the attached map titled "Nashville Wal-Mart -Watershed Basin". This area
includes the subject property owned by Wal-Mart Stores East, LP (16 acres +/-), 3
outparcels (adjacent to the subject property) owned by David Rose and partners (3.5 acres
+/-), and 40 acres +/- of undeveloped, agricultural farmland owned by David Rose and
partners.
Of the 60 acres, only the Wal-Mart property is within the town limits of Nashville, NC.
The remaining acreage is within Nash County. The Wal-Mart property and the 3
outparcels are zoned B-1 General Business District. 40 acre tract is zoned A-1
Agricultural District.
As noted in the Pre-construction Notification (PCN) document, the subject project
impacts an existing wetland and an existing intermittent, unimportant stream. The
wetland impacts are less than 0.10 acres. The stream impact is 818 lf. The stream flows
via an unnamed tributary to Stony Creek, approximately 1 mile downstream.
The Wal-Mart property will be fully developed upon completion of the proposed project.
The project will include a 153,000 square foot store and a 739 space parking lot. In an
effort to study the impact of commercial development on water quality standards, Wal-
Mart is partnering with Dr. Bill Hunt, P.E., Assistant Professor and Extension Specialist,
North Carolina State University, to design and construct Low Impact Development (LID)
measures. The measures that will be constructed with the project include constructed
wetlands, bioretention cells, and permeable pavement. The study will measure the
impacts that LID measures have on pollutants such as nutrients, sediments, bacteria, and
temperature as well as impacts on hydrology such as runoff, evapo-transpiration, and
infiltration when compared to commercial developments without LID measures or
commercial developments with more traditional measures such as wet ponds, dry ponds,
grass swales, level spreaders, etc.
With regard to indirect and cumulative impact of future development within the study
area, the anticipation is that there will be little or no impact on water quality standards.
Future development within the study area is likely to first. occur on the 3 outparcels
adjacent to the Wal-Mart property. The outparcels are expected to be developed as
typical commercial properties such as restaurants. Each parcel will be developed
individually and is anticipated to be 85-90% impervious. Please note that the stormwater
runoff measures proposed for the Wal-Mart project are designed to handle post-
development runoff from the 3 outparcels. Therefore, there will be no additional impact
with the development.

1
It is anticipated that the remaining 40 acres of agricultural farmland will be developed
into commercial and/or retail space in 5-10 years. Before the property can be developed,
it will have to be re-zoned from agricultural district to general business district.
Furthermore, the property will have to be annexed into the Town of Nashville in order to
be eligible to receive city water and sanitary sewer service. Therefore, the property will
be required to conform to the stormwater management requirements of the Town of
Nashville. Per the attached letter, the Town has committed to requiring on-site
stormwater management measures for development on this property. Therefore, there
will be no additional impact with this future development.

Dear Ms. Karoly,

LOUISE W. HINTON
TOMMY I. ROGERS
This letter has been written pursuant to a request by Stocks Engineering, PA's in regards to the
proposed Wal-Mart located on Eastern Avenue in the Town of Nashville. As it pertains to
stormwater for projects where adequate capacity can not be demonstrated in the receiving
storm drainage system, the owner or developer may make improvements in the downstream
drainage system to provide adequate capacity or install a stormwater management system. This
system at a minimum will not increase the stormwater runoff rate from the property as a result of
development of that property.
If you have any further questions or require additional information please feel free to contact me
at [phone] ext. 233.
Sincerely,

Preston Mitchell
