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.

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 reads feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 'j . 5- feet in the forebay, the sediment shall be removed.

1. Protect Description: The Project is proposed to be a residential town home
project 13.87 acre parcel with 71 units and commercial lot on the frontage of Village
Road. infrastructure will include construction of road, curb, gutter, storm drainage
system, water, and sewer. The land disturbing activity associated with the project will
consist of clearing and grubbing of vegetation, preservation of existing trees, grading of
the site, and sediment and erosion control measures such as a silt fence, gravel
construction entrance, and the wet detention pond will function as a sediment basin.
The total area which will be disturbed for this project is 12 acres. Total impervious area
will be 7.43 AC for the proposed construction of roads, sidewalks, and residential units.
The future commercial lot will be allowed 1.37 acres of impervious surface that will be
treated by the pond.
2. Site Description: The project site is in Brunswick County, NC, located just off of
Village Road just north of ,intersection of Cleatwood Road. The property on which the
developme-AA will -take place is currently in the Town ofU.; and corporate limits.
On site soils consist mainly of Leon and Ba /meade s is:rThese soils are mainly loamy,
fine sands. Approximate) 0.2 acres of wet ands are located on the parcel and have
been subn,idev' for approval to the USACE. o wetlands tAdii be impacted by the project
construction.
General slope of the site is from south to north towards the rear of the site.
Land use in the vicinity is residential, light commercial, and rural agricultural.
3. Ad{acent Property: The areas adjacent to the project site are residential areas
and one commercial site that is currently used for mobile home rentals.
4. Drainage Considerations: There is an existing wetland area on the property
that is connected to" Mill Branch Creek. There are d-." .hes on site that feed into the
existing wetlands.
The road will be bounded with curb- and gutter to curb and tied to a collection system of
piping. All•-& the collection system will be directed tc a proposed wet detention basin
that is sized for the 1" runoff of impervious areas. The runoff from the buildings will be
directed 'into the collection system and sent to the basin. The basin is sized to provide
sufficient runoff capacity filtration for the entire allowable impervious area. The wet
detention `t,4sin is to provide detention of the pre-con,iruction and post -construction
runoff difference and meet the 90% TSS water quali s requirements. The amount of
retention,was based on the Type III rainfall distribution of the 25 year, 24-hour storm.
Calculations are provided.
5. Erosion Control Considerations: The following erosion control measures are
used on this project:
1. Teriiporary Gravel Construction Entrance/Exit
Bellamy Place Townhomes
January 2007

To prevent sediment from leaving the site, temporary gravel construction entrances
should be installed where the access road enters the site and instersects with
Village. For dimensions and specifications, see construction details.
2. Land Grading
The existing slope of the site is from south to north towards the front of the parcel.
Most of the disturbed areas on the site will sheet flow to the existing drainage
patterns on the site.
3. Silt Fence
Silt fence should be installed prior to clearing and grading activities. Silt fence
should be checked routinely. If needed, silt fence should be cleaned and replaced
if damaged. See Construction Detail for dimensions and specifications.
4. Wet Detention Basin
A wet detention basin will be constructed for long term runoff pollutant control, and
this area will be used as a sediment basin during construction. Outlet control
structure with rip rap energy dissapator will be installed when basin is excavated
and 30' sodded vegetated. filter will be placed after the rip rap to provide additional
filtering prior to discharge into the existing wetland.
6. Construction Schedule:
1. Obtain plan approval and other applicable permits.
2. Hold pre -construction meeting at least one week prior to beginning construction.
3. Install temporary construction entrance/exits.
4. Before clearing and grading of the site, install silt fencing, detention basin with outlet
structure, and clean and replace as necessary.
5. Begin clearing and grading of the site.
6. Install storm piping.
7. Install new roadway.
8. Sod/Seed, mulch, and tack immediately to establish proper vegetation.
9. All erosion and sediment control practices will be inspected weekly and after each
rainfall event. Needed repairs will be made immediately.
10. After the entire covered area is stabilized, all temporary measures will be removed
and permanent vegetative repairs to be completed.
7. Vegetation Plan:
1. After complete stabilization of the entire covered area, top cover soils will be
roughened by making 1"-2" deep grooves perpendicular to the slope.
Bellamy Place Townhomes
January 2007

2. Spread lime (agricultural limestone) evenly over the area at a rate of 1.5 tons/acre;
spread 10-10-10 fertilizer at a rate of 1000 lb/acre and incorporate into the top 6" of
soil.
3. Loosen surface prior to applying seed.
4. Broadcast seed at recommended rates.
5. Rake seed into the soil and lightly pack to establish good contact.
6. Mulch with 4000 lb/acre grain straw or equivalent and anchor by weighted farm disc
set nearly straight or other mulch anchoring tool.
7. Mow as needed and refertilize in late winter or early spring by topdressing with 10-
10-10 fertilizer.
8. Graded surfaces shall not be exposed without grass coverage for more than 15
day:. If grades are not complete and exposure is more than 15 days, temporary
seed with rye grain at 50 lb/acre.
8. Maintenance Plan:
1. Contractor shall maintain all sedimentation and erosion control devices during
construction.
2. All devices shall be checked after each rain event and weekly. Repairs shall be
made immediately when detected.
3. Any deficiencies shall be brought to the immediate attention of the Engineer.

1. Proiect Description: The Project is proposed to be a residential townhome
project 14 acre parcel with 72 units. Infrastructure will include construction of road, curb,
gutter, vegetated storm drainage system, water, and sewer. The land disturbing activity
associated with the project will consist of clearing and grubbing of vegetation,
preservation of existing trees, grading of the site, and sediment and erosion control
measures such as a silt fence, gravel construction entrance, and a check dams. The
total area which will be disturbed for this project is 9.5 acres. Total impervious area will
be 6.2 AC for the proposed construction of roads, sidewalks, and residential units.
2. Site Description: The project site is in Brunswick County, NC, located just off of
Village Road just north of intersection of Cleatwood Road. The property on which the
development will take place is currently in the Town of Leland corporate limits.
On site soils consist mainly of Leon and Baymeade soils. These soils are mainly loamy,
fine sands. Approximately 0.2 acres of wetlands are located on the parcel and have
been submitted for approval to the USACE.
General slope of the site is from south to north towards the rear of the site.
Land use in the vicinity is residential and rural agricultural.
3. Adiacent Property: The areas adjacent to the project site are residential areas
and one commercial site that is currently used for mobile home rentals.
4. Drainage Considerations: There is an existing wetland area on the property
that is connected to Mill Creek. There are ditches on site that feed into the existing
wetlands.
The road will be bounded with curb and gutter to curb and tied to a collection system of
piping. All of the collection system will be directed to a proposed wet detention basin
that is sized for the 1. r_ uno -,bf impervious areas. The runoff from the buildings will be
directed into the collection system and sent to the basin. The basin is sized to provide
sufficient runoff capacity filtration for the entire allowable impervious area. The wet
detention basin is to provide detention of the pre. -construction and post -construction
runoff difference and meet the 90% TSS water quality requirements. The amount of
retention was based on the Type III rainfall distribution of the 25 year, 24-hour storm.
Calculations are provided.
S. Erosion Control Considerations: The following erosion control measures are
used on this project:
1. Temporary Gravel Construction Entrance/Exit
To prevent sediment from leaving the site, temporary gravel construction entrances
should be installed where the access road enters the site and instersects with
Village. For dimensions and specifications, see construction details.
2. Land Grading
The existing slope of the site is from south to north towards the front of the parcel.
Most of the disturbed areas on the site will sheet flow to the existing drainage
patterns on the site.

3. Silt Fence
Silt fence should be installed prior to clearing and grading activities. Silt fence
should be checked routinely. If needed, silt fence should be cleaned and replaced
if damaged. See Construction Detail for dimensions and specifications.
4_ Wet Detention Basin
A wet detention basin will be constructed for long term runoff pollutant control, and
this area will be used as a sediment basin during construction. Outlet control
structure with rip rap energy dissapator will be installed when basin is excavated
and 30' sodded vegetated filter will be placed after the rip rap to provide additional
filtering prior to discharge into the existing wetland.
6. Construction Schedule:
1. Obtain plan approval and other applicable permits.
2. Hold pre -construction meeting at least one week prior to beginning construction.
3. Install temporary construction entrance/exits.
4. Before clearing and grading of the site, install silt fencing, detention basin with outlet
structure, and clean and replace as necessary.
5. Begin clearing and grading of the site.
6. Install storm piping.
7. Install new roadway.
8. Sod/Seed, mulch, and tack immediately to establish proper vegetation.
9. All erosion and sediment control practices will be inspected weekly and after each
rainfall event. Needed repairs will be made immediately.
10. After the entire covered area is stabilized, all temporary measures will be removed
and permanent vegetative repairs to be completed.
7. Vecietation Plan:
1. After complete stabilization of the entire covered area, top cover soils will be
roughened by making 1 "-2" deep grooves perpendicular to the slope.
2. Spread lime (agricultural limestone) evenly over the area at a rate of 1.5 tons/acre;
spread 10-10-10 fertilizer at a rate of 1000 lb/acre and incorporate into the top 6" of
soil.
3. Loosen surface prior to applying seed.
4. Broadcast seed at recommended rates.
5. Rake seed into the soil and lightly pack to establish good contact.

6. Mulch with 4000 lb/acre grain straw or equivalent and anchor by weighted farm disc
set nearly straight or other mulch anchoring tool.
7. Mow as needed and refertilize in late winter or early spring by topdressing with 10-
10-10 fertilizer.
8. Graded surfaces shall not be exposed without grass coverage for more than 15
days. if grades are not complete and exposure is more than 15 days, temporary
seed with rye grain at 50 lb/acre.
8. Maintenance Plan:
1. Contractor shall maintain all. sedimentation and erosion control devices during
construction.
2. All devices shall be checked after each rain event and weekly. Repairs shall be
made immediately when detected.
3. Any deficiencies shall be brought to the immediate attention of the Engineer.
