PROJECT NARRATIVE
SHOPPES AT SANFORD - SANFORD, NC
The proposed development fronts both NC Highway 87 and Wilson Road, with the majority of the frontage being
along NC Highway 87. Currently, the site consists mainly of farmland with a portion of the site being wooded.
There are several existing drainage swales running through the site along with two wetland areas. The current
topography of the site slopes from Horner Boulevard and Wilson Road to the rear of the site (west). The majority of
the site drains to one of the two wetland areas, which outlet to the western portion of the site. The northern most
wetland area continues off-site, and disturbance of this area will be limited to less than 0.5 acres. The southern
most wetland area was determined to be isolated and will be abandoned completely. The remaining portion of the
site drains to a drainage swale which outlets from the site, downstream of the previously mentioned wetland area.
There are several stormdrain pipes located along Homer Boulevard which drain to the site. The runoff from these
pipes will be re-routed through a stormdrain by-pass system that will run through the site and outlet off-site, as in
pre-developed conditions. The current plan is to construct a Wal-Mart Supercenter along with a Retail Shops
Building and several outlot areas. There will be a regional Stormwater Management Pond which will be designed to
handle the runoff from the entire development. This pond will be designed for Water Quality and Quantity
purposes. The total developed area that will pass through the Pond will be approximately 50 acres.
Construction will include the Wal-Mart and Retail Shops Building plus accompanying parking and landscaped areas
along with the Stormwater Management Pond. Several outlot areas will also be graded as part of this project. The
site contains approximately 50 acres, all of which will be disturbed during construction activities. The stormwater
will sheet flow across the paved and landscaped areas to proposed inlets, which will lead to the aforementioned
Pond. The Stormwater Management Pond will be designed to detain the first inch of runoff over a 48 hour period,
detain the 2 and 5 year storm events while passing the 10, 25, 50 and 100-yr storm events.
The Stormwater Management Pond will serve as a Sediment Basin during construction activities. There will be
several sediment traps installed during construction activities as well. Silt fence, inlet protection, construction
entrances, stone filters, and diversion ditches will also serve as erosion and sediment control devices. After the site
has been stabilized, the silt fence, inlet protection and construction entrances will be removed, the Sediment Basin
will be cleaned and converted to the Stormwater Management Pond, and the site will be graded to its final
configuration.

Permittee: Sanford Retail Investments, LLC
Address : 2361 Centennial Avenue, Aiken, SC 29803 Phone No. 803-502-2288
I. - Monthly, or after every runoff producing rainfall event, whichever comes first:
A. Inspect the trash rack; remove accumulated debris, repair / replace if it is not
fnctioning.
B. Inspect and clear the orifice of any obstructions. If a pump is used as the
drawdown mechanism, pump operation will be checked. A log of test runs of the
pump will be kept on site and made available to DWQ personnel upon request.
C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair
eroded areas before the next rainfall event.
D. If the pond is operated with a vegetated filter, the filter will be checked for
sediment accumulation, trash accumulation, erosion and proper operation of the
flow spreader mechanism. Repairs/cleaning will be done as necessary.
II. Quarterly (Four times a year):
A. Inspect the collection system (i.e. catch basins, piping, grassed swales) for proper
functioning. Accumulated trash will be cleaned from the basin grates, basin
bottoms, and piping will be checked for obstructions and cleared as required.
B. Pond inlets will be checked for undercutting. Riprap or other energy dissipation
structures will be replaced, and broken pipes will be repaired.
III. Semi-annually (twice a year):
A. Accumulated sediment from the bottom of the outlet structure will be removed.
B. The forebay depth will be checked at various points. Sediment removal is
required when the depth is reduced to 75% of the original forebay design depth of
4 feet.
C. Grassed swales, including the vegetated filter if applicable, will be re-seeded
twice a year as necessary.

POND MAINTENANCE REQUIREMENTS
PAGE 2
IV. Annually (Once a year):
A. The pond depth will be checked at various points. Sediment removal is required
when the depth is reduced to 75% of the original design depth or 5.6 feet,
whichever is greater. The design depth for the pond is 12 feet therefore the 9.0
foot minimum would apply. The depth is measured vertically from the orifice
down to the pond's bottom. Sediment must be removed to at least the original
design depth.
V. General:
A. Mowing of the side slopes will be accomplished according to the season.
Maximum grass height will be 6".
B. Cattails are encouraged along the perimeter, however they will be removed when
they cover more than %2 the surface area of the pond. The best time to cut them is
at the end of the growing season, in November. Environmentally sensitive
chemicals for use in killing cattails can also be used. Contact your nearest
Agricultural Extension Agent.
C. The orifice is designed to draw down the pond in the 2-5 days. If drawdown is not
accomplished in that time, the orifice will be replaced with a larger or smaller
orifice. Slow drawdown may be attributed to a clogged system. The source of the
clogging will be found and eliminated.
D. All components of the detention pond systems (2) will be kept in good working
order. Repair or replacement components will meet the original design
specifications as per the approved stormwater plan. If previously approved
components are determined to be ineffective, the component must be redesigned
and/or replaced.
VI. Special Requirements:
I, Lac , hereby acknowledge that I am the financially
responsible party for maintenance of this detention pond. I will be responsible for the
performance of the maintenance as outlined above, as part of the Stormwater
Management Permit received for this project.

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

1, 1 PRO.IEff NARRATIVE
SHORES AT SANFORD - SANFORD, NC
The proposed development fronts both NC Highway 87 and Wilson Road, with the majority of the frontage being
along NC Highway 87. Currently, the site consists mainly of farmland with a portion of the site being wooded.
There are several existing drainage swales running through the site along with two wetland areas. The current
topography of the site slopes from Horner Boulevard and Wilson Road to the rear of the site (west). The majority of
the site drains to one of the two wetland areas, which outlet to the western portion of the site. The northern most
wetland area continues off-site, and disturbance of this area will be limited to less than 0.5 acres. The southern
most wetland area was determined to be isolated and will be abandoned completely. The remaining portion of the
site drains to a drainage swale which outlets from the site, downstream of the previously mentioned wetland area.
There are several stormdrain pipes located along Homer Boulevard which drain to the site. The runoff from these
pipes will be re-routed through a stormdrain by-pass system that will run through the site and outlet off-site, as in
pre-developed conditions. The current plan is to construct a Wal-Mart Supercenter along with a Retail Shops
Building and several outlot areas. There will be a regional Stormwater Management Pond which will be designed to
handle the runoff from the entire development This pond will be designed for Water Quality and Quantity
purposes. The total developed area that will pass through the Pond will be approximately 50 acres.
Construction will include the Wal-Mart and Retail Shops Building plus accompanying parking and landscaped areas
along with the Stormwater Management Pond. Several outlot areas will also be graded as part of this project. The
site contains approximately 50 acres, all of which will be disturbed during construction activities. The stormwater
will sheet flow across the paved and landscaped areas to proposed inlets, which will lead to the aforementioned
Pond, The Stormwater Management Pond will be designed to detain the first inch of runoff over a 48 hour period,
detain the 2 and 5 year storm events while passing the 10, 25, 50 and 100-yr storm events.
The Stormwater Management Pond will serve as a Sediment Basin during construction activities. There will be
several sediment traps installed during construction activities as well. Silt fence, inlet protection, construction
entrances, stone filters, and diversion ditches will also serve as erosion and sediment control devices. After the site
has been stabilized, the silt fence, inlet protection and construction entrances will be removed, the Sediment Basin
will be cleaned and converted to the Stormwater Management Pond, and the site will be graded to its final
configuration.

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
H. REQUIRED ITEMS CHECKLIST

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth read6n-1- feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads feet in the forebay,1e sediment shall be removed.

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90%TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
