Town of Navassa Affordable Housing Project
Forest Hills Drive
April,2002

1. Project Description: The Town of Navassa Affordable Housing Project is a
proposed project to be constructed in the near future in Brunswick County. The land
disturbing activity associated with the project will consist of clearing and grubbing of
trees, clearing existing drainage swales, grading of the site, and sediment and erosion
control measures such as a silt fence, gravel construction entrance, and a sediment
basin. Further into construction, the sediment basin will be converted to an onsite
detention pond. Also included in the project will be storm piping, water lines, and sewer
lines, and paved roads with curb and gutter. The total area which will be disturbed for
this project is 4.58 acres.
2. Site Description: The project site is in Brunswick Co., NC, located directly to
the south of where Old Mill Road intersects with Main Street. The property on which the
development will take place is currently owned by The General Baptist State Convention
of North Carolina, Inc. (GBSC).
On site soils consist mainly of Baymeade, Blanton, Goldsboro, Mandarin, and Norfolk
soils. These soils are mainly loamy, fine sands.
There are no existing wetlands onsite.
New construction onsite will consist of paved roads with curb and gutter, curb inlets,
storm piping, and a detention pond. Also included will be a gravity sewer collection
system and a water distribution system.
General slope of the site from north to south towards the back of the site.
Land use in the vicinity is residential.
3. Adjacent Property: The areas adjacent to the project site are mostly
residential areas.
4. Drainage Considerations: Drainage calculations to determine the size of storm
piping is attached in the appendix — Storm Piping Calculations. The project site is
graded so that stormwater drains into strategically placed curb inlets and existing
swales. From the curb inlets, storm water will empty into a network of storm pipes which
drain into an onsite stormwater detention pond. The storm pipe network empties into
the detention pond below the permanent pool elevation. Existing swales also drain into
the pipe drainage network which empties into the detention pond.
Calculations showing the sizing of the stormwater detention pond are shown in the
attached appendix — Detention Pond Sizing Calculations. The pond is designed to
receive a Total Suspended Solids (TSS) removal of 90%. Based on a 6 foot depth of
the permanent pool, a total drainage area of 23.21 acres, and an impervious area of
39.8%, the Surface Area to Drainage Area ratio (SAIDA) 2.10%. With 90% TSS there is
no need for a vegetative filter. The required temporary storage volume was determined
using the Schueler Method and basing calculations on a 1" rainfall event. Then the
permanent pool volume is determined based on the permanent pool surface area and
the depth of the pool. Then 20% of that volume is to be used for the forebay volume.

Forest Hills Drive
April, 2002

Next the orifice was sized at 2" in diameter to keep the drainage time of the 1 inch storm
event between 2 and 5 days. A principal spillway was designed to drain stormwater that
rises above the temporary pool elevation. It was sized using the excess runoff created
from pre and post development for the 25 year storm. An emergency drainage spillway
was sized to handle the same flow as the principal spillway, and will be one foot above
the temporary pool elevation.
In addition, a bypass swale will be constructed at the north end of the site. The swale
will serve the function of draining runoff from outside the project boundary and emptying
it into the existing creek to the east of the site.
5. 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 Forest Hills Drive enters the site and where
Church Street enters the site. For dimensions and specifications, see construction
details.
2. Land Grading
The existing slope of the site is from north to south towards the back of the lot.
Most of the disturbed areas on the site will drain into curb inlets which will empty
into stormwater piping and drain into an onsite detention pond.
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. Inlet Protection
Inlet protection consisting of a small portion of silt fence surrounding proposed
curb inlets will be utilized to prevent sediment from entering the drainage system.
See Construction Detail for dimensions and specifications.
5. Detention Pond
A detention pond will be built to control sediment from leaving the site. It will be
constructed at the south end of the lot. See Construction Detail for dimensions
and specifications.
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 and clean and replace as
necessary.
Town of Navassa Affordable Housing Project
Forest Hills Drive
April,2002

5. Build onsite detention pond.
6. Check existing swales and clear as necessary.
7. Begin clearing and grading of the site.
8. Construct onsite curb inlets with inlet protection.
9. Install storm piping.
10. Install sewer and waterlines and pave new roadway.
11. All erosion and sediment control practices will be inspected bi-weekly and after each
rainfall event. Needed repairs will be made immediately.
12. 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.
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.

Dear Zach:
I received the resubmitted information on March 1,2002,which included a map of the offsite drainage area.
The existing offsite areas,which include a portion of the Navassa Community Center,the Fire Department and all
the land between the Fire Department and Lot#1,must be accounted for at the full build-out potential. There is no
guarantee that the Division will be involved in issuing permits for any of the future improvements to the Community
Center, to the Fire Department,or to the empty land,if the land disturbances are less than 1 acre.In situations like
this, where some of the offsite property is not under the applicant's control, we recommend that the runoff be
bypassed around the proposed system. If bypass cannot be achieved,you must account for the possible development
of that site at the full-build-out potential,generally between 85%and 90%impervious,depending on local zoning
requirements.
From the calculations,the future development consists of 13 lots @3500 per lot plus a road, which have
been accounted for as offsite drainage. Please clearly identify the location of these 13 future lots on the drainage
area map and label it "FUTURE DEVELOPMENT" on the plans. Future areas should be considered part of the
onsite drainage area,and should not be considered as"offsite"drainage.Offsite drainage should be only those areas
that are not owned by the applicant.
The calculations indicate that a total of 12.72 acres of offsite area exists(21.74-9.02). Of this 12.72 acres,
please determine how much property is associated with the Community Center,Fire Department,and the land tract.
Once you know this, you can then determine the appropriate built-upon area limit to account for in the pond. An
increase in the pond size may be needed.
Swale#1 has a note that says it begins at Main Street. What is the drainage area for this swale from Main
Street?This swale is directed into the proposed pond,and all of the upstream drainage into the swale is considered
offsite drainage.

The drainage area line must not cut across a lot.It must include all of the lot area,since low density has not
been met within the project limits(excluding offsite drainage).
Please provide 2 copies of the revised plan sheets. Only one copy was submitted with the last revision.
I think that you are making this calculation more difficult than it has to be and that it is being made more
difficult for me because you are not providing me with clear information regarding the drainage area. Remember
that drainage area,offsite drainage area,offsite impervious area,and project area are all different things.The project
area should include the area of all the lots(proposed and future),and roads.The drainage area to the pond is the total
of the on-site(i.e.,property owned by the applicant)and offsite(i.e.,property not owned by the applicant)drainage
areas.

Dear Mrs. Lewis,
Mrs. Lewis,
Attached are the corrected portions of the Stormwater Permit application for the Town of Navassa
Affordable Housing Project. The corrections are in response to your letter to Shane Lippard dated
February 28, 2002. The following changes have been made.
1. The plan cover sheet has been changed to more accurately show the onsite and offsite drainage areas.
2. Corrections have been made to the deed restrictions to match your requests.
3. An answer has been provided to Section III, Part 7 of page 3 of the Stormwater Permit Application
Form to explain how offsite impervious area was determined.
Included are only the pages where changes were made and have been initialed and dated. Let me know if
there is anything else you might need.
Sincerely,

Dear Shane:
Please provide a map which clearly shows the entire drainage area to the pond,both on-site and off-site.
Please revise Section 7 of the deed restrictions to include the statements I-2, II-1, and V-2 as provided on the
attached sheet. Statement#2 limiting BUA in the copy of the restrictions that was submitted does not contain the
all the necessary language, and the words "outparcels " and "future development" in Statement #5 need to be
replaced with "lots".
FYI- The new forebay volume is outside of the acceptable range of 18%-22%. Large, shallow, forebays take up
too much of the surface area that could be at the design depth. In this case,however,the forebay is proposed to be
as deep as the pond,therefore, it is not an issue for this project. Please be aware of this for future projects, where
the forebay may be shallower than the pond.
Please provide an answer for Section III. Part 7 of the application,regarding how the offsite area was derived.

INFORMATION PERTAINING TO DEED RESTRICTIONS
AND PROTECTIVE COVENANTS
In accordance with Title 15 NCAC 2H.1000, the Coastal Stormwater Management Regulations, deed restrictions
and protective covenants are required for certain developments where lots will be subdivided and sold. Deed
restrictions and protective covenants are necessary to ensure that the development maintains a"built-upon" surface
area consistent with the applicable regulation limiting built-upon area.The following deed restrictions and covenants
must be recorded prior to issuing the Stormwater Management Permit:
I. For All Projects:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management
Permit Number , as issued by the Division of Water Quality under NCAC 2H 1000.
filfr The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain
compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent
of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of
the Division of Water Quality.
,.III In addition to all 5 above,restrictions for Low Density Subdivisions
( 1. � The maximum allowable built-upon area per lot is square feet. This allotted amount includes
�� any built-upon area constructed within the lot property boundaries, and that portion of the right-of-way
between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to,
structures, asphalt, concrete,gravel, brick stone,slate,and coquina, but does not include raised, open wood
decking, or the water surface of swimming pools.
2 Filling in or piping of any vegetative conveyances (ditches, swales, etc) associated with the development
except for average driveway crossings, is strictly prohibited by any persons.
3. Each lot will maintain a 30'wide vegetated buffer between all impervious areas and surface waters.
4. All roof drains shall terminate at least 30'from the mean high water mark of surface waters.
III In addition to all of the above,these restrictions apply if a low density subdivision has curbs and gutters:
1. Filling in, piping or altering any designated 5:1 curb outlet Swale associated with the development is
prohibited by any persons.
2. This project proposes a curb outlet system. Each designated curb outlet swale shown on the approved plan
must be maintained at a minimum of 100'long with 5:1 (H:V) side slopes or flatter, have a longitudinal
slope no steeper than 5%, carry the flow from a 10 year storm in a non-erosive manner, and maintain a
dense vegetated cover.
IV In addition to the above,this restriction applies if any lots lie within CAMA's AEC:
1. "Lots within C_A11L4.'s Area of Environmental Concern may have the permitted maximum built-upon area
reduced due to CAMA jurisdiction within the AEC."
Page 1 of 2

V For High Density Residential or Commercial Subdivisions:
(In addition to I-1 through I-5)
1. The maximum allowable built-upon area per lot is square feet. This allotted amount includes
any built-upon area constructed within the lot property boundaries, and that portion of the right-of-way
between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to,
structures, asphalt, concrete, gravel, brick stone, slate, coquina and parking areas, but does not include
raised, open wood decking, or the water surface of swimming pools.
11, All runoff from the built-upon areas on the lot must drain into the permitted system. This may be
accomplished through providing roofdrain gutters which drain to the street,grading the lot to drain toward
the street, or grading perimeter swales to collect lot runoff and directing them into the stormwater system
or into the street. Lots that will naturally drain into the system are not required to provide these additional
measures.
VI For Shopping Centers with outparcels or future development:
(In addition to I-1 through I-5)
1. The maximum built-upon area for outparcel(s)and future areas shown on the approved plans is
square feet. This allotted amount includes any built-upon area constructed within the property boundaries,
and that portion of the right-of-way between the lot lines and the edge of the pavement. Built upon area
includes, but is not limited to, structures, asphalt, concrete,gravel, brick stone, slate, coquina and parking
areas, but does not include raised, open wood decking, or the water surface of swimming pools.
2. The runoff from all built-upon area on the outparcel or future area must be directed into the permitted
stormwater control system.
3. Built-upon area in excess of the permitted amount will require a permit modification.
4. The connection from the outparcel's collection system into the stormwater control shall be made such that
short-circuiting of the system does not occur.

Maintenance activities shall be performed as follows:
I. After every significant runoff producing rainfall event and at least monthly:
a. ln.spect. 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 occur:, within
2 to 5 days as designed.
2. Repatr. 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 desi`n 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.

RE: Stormwater Management Permit Application
Dear Mrs. Lewis,
Enclosed are 2 copies each, of The Stormwater Management Permit Application and design plans for
Town of Navassa Affordable Housing Project for your review and approval. We have made all the
changes you had requested in your letter to John D. Fuller dated February 5, 2002. The following are
changes we have made to the plans;
1. Permanent pool dimensions have been relocated.
2. Utility easement has been located.
3. Vegetated shelf for Stormwater Detention pond has been correctly labeled.
4. Vicinity map has been adjusted to include the intersection of two major roads.
5. Proposed deed restrictions have been included in this submittal package.
6. Stormwater Management Permit Application Form has been altered to not show house,
driveway,patio, and sidewalk areas. Only the total impervious area for the"On-site
buildings" space.
7. Offsite drainage has been more thoroughly explained in this permit application. We have
taken into account the offsite drainage to the north of the site. Calculations have been done
for future offsite impervious area and pond size has been increased to accommodate this
additional runoff
Let me know if there is anything else you might need.
Sincerely,
,eg/. . G�

Subject: REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 011121
Town of Navassa Affordable Housing Project
Brunswick County
Dear Mr. Fuller:
The Wilmington Regional Office received a Stormwater Management Permit Application for Town of
Navassa Affordable Housing Project on November 26, 2001. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwater review:
1. Please relocate the permanent pool dimensions so that they are readable. They are lost in the
plan clutter.
2. The pond must be located in a recorded access/drainage easement.
3. Sheet C-1 incorrectly identifies the 6:1 vegetated shelf as the vegetated "filter". The vegetated
filter is a structure that is located at the outlet to provide additional TS S removal when the 85%
TSS chart is used. Please identify the 10'vegetated shelf correctly on sheet C-1.
4. Please add the nearest intersection of two major roads to the vicinity map.A major road is any
1, 2 or 3 digit NC,US or interstate highway.
5. Please provide a copy of the proposed deed restrictions to include all required conditions and
limitations for a high density subdivision project.
6. For subdivisions,it isn't necessary to breakdown the 3,500 ft2 per lot BUA.It doesn't matter how
much is house, driveway, patio, or sidewalk, as long as the total is 3,500 or less. Please just
show the total BUA for the lots, i.e., 3500 x 25 = 87,500 ft2 in the "On-site buildings" space.
7. The application'does not account for any offsite drainage, but the delineated drainage area
clearly shows offsite drainage. Please account for all offsite, existing and future development
within the drainage area at the build-out potential.Is the majority of the drainage area developed
or considered future development?
