High Density Residential Subdivisions I DEC 1 8 2008
In accordance with Title 15 NCAC 2H.1000, the Stormwater Management Regulations, deed restrictions and
protective covenants are required for High Density Residential Subdivisions where lots will be subdivided and
sold and runoff will be treated in an engineered stormwater control facility. Deed restrictions and protective
covenants are necessary to ensure that the development maintains a "built -upon" area consistent with the
design criteria used to size the stormwater control facility.
I, maid Murphy, , acknowledge, affirm and agree by my signature below, that I will
cause the followng deed restrictions and covenants to be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number! 1W 1:3-c*5IZ C)j , as issued by the Division of Water Quality under
NCAC 2H.1000.
2. 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written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.
6. The maximum allowable built -upon area per lot is 3 50 0 square feet. This allotted amount
includes any built -upon area constructed within the 0 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.
OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following:
6. The maximum built -upon area per lot, in square feet, is as listed below:
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
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.
7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street, grading
the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them
into a component of the stormwater collection system. Lots that will naturally drain into the system are
not required to provide these additional measures.

Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,

This system (check one):

incorporate pretreatment other than a forebay.
Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a clam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

and Maintenance Agreement
l will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
❑ does does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does Q does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Narrative
Description:
The site is located approx. 2.0 miles from the intersection of 1-140 and NC-133. Travel
south onNC-133 nearly 2 miles and the entrance to the site will be on the west side of
Castle 1-layne Rd.
Total site area is approx. 95.16 acres.
Total disturbed acreage is approx. 90.37 acres.
Soils to be disturbed are mainly Wr, Ra, Cr, Se, On, Jo, & Pn.
The purpose of this project is to develop a residential subdivision and three condo
buildings.
Stormwater will be treated in 2 wet ponds.
Erosion Control Measures:
The attached plans and specifications state or show required Sediment and Erosion
Control measures to be taken.
Gravel construction entrance will be installed as shown.
Silt fence will be installed at places sediment has the ability to leave the site.
Inlet protection will be installed as shown on plan.
Outlet protection will be installed as shown on plan.
Mulch will be installed where indicated on plan.
Crass -lined Swale will be installed as shown on plan.
Temporary porous baffles will be installed as shown on plan.
Seeding
Construction Sequence:
Phase 1:
The gravel constrcution entrance will be immediately installed as shown on plan. All silt
fence labeled "ph. 1 silt fence" will be installed immediately. The bypass swale shall be
constructed prior to the installation of the ditch plugs on the south & east side of pond #2
& prior to the construction of pond 42. The 4 ditch plugs on the south & east side of
pond 42 shall be installed & the portion of the ditch filled where labeled. The 4 ditch
plugs located northwest & 1 ditch plug located northeast of the multi -family shall be
installed. The ditch plug at the rear of lot 9104 shall be installed. The ditch plug on lot
919 shall be installed. Pond 42 area shall be cleared and the existing ditches shall be
filled where labeled on the plan using suitable material from the bypass Swale & the
interior area of pond #2 (if necessary). Pond #2 area shall be seeded & stabilized (per
specs). The bypass culverts and energy dissipaters shall then be installed. Next, corridors
for the roads and sanitary sewer shall be cleared & the sewer pipe will be installed. Upon
completion of any phase of activity side slopes will be seeded/stabilized within 21
calendar days of no construction, all other disturbed areas will be seeded/stabilized within
15 calendar days of no construction

1DEC 1 8 2008
�v;
Phase 2:
The remaining silt fence will be installed as shown on the plan. The ponds, which will
serve as sediment basins, are to be dug next with temporary faircloth skimmer orifice &
temporary porous baffles installed while clearing land so as to have area to spread spoil.
Faircloth skimmer & temporary porous baffles shall be removed once site is stabilized &
sediment basins are converted to stormwater ponds. Site is to be graded to direct runoff
to the ponds. Storm drain system & remaining utilities may be installed. Swales shall be
constructed. Inlet & outlet protection are to be installed. Upon completion of any phase
of activity side slopes will be seeded/stabilized within 21 calendar days of no
construction, all other disturbed areas will be seeded/stabilized within 15 calendar days of
no construction.

Reference: Stormwater Infiltration Study at Riverside Tract, Castle Hayne Rd. in
Wilmington, New Hanover County, NC
Dear Jeff,
Land Management Group, Inc. portions of the above mentioned parcel to describe the
soil profile and quantify the depth to the seasonal high water table (SHWT) at selected
locations. The following comments summarize our findings.
The soils at this site are mapped as Craven, Wrightsboro, Rains, and Onslow soil series
in the Soil Survey of New Hanover County (USDA, 1977). An investigation of the site
confirms the presence of Craven, Wrightsboro, Rains, and Onslow soils as described in
the attachments. Borings #1, 2 and 3 appears to be Wrightsboro soil series and has an
estimated seasonal high water table that ranges from 2,Z to 40 inches from the soil
surface due to the existing site drainage. Borings # 6 & 7 appears to be Onslow soil
series with loamy subsoil and has an estimated seasonal high water table that is at least
30" from the soil surface. Boring # 9 appears to be Craven soil series and has an
estimated seasonal high water table of at least 28" from the soil surface. Boring # 8
appears to be Rains soil series and has an estimated seasonal high water table of 12"
from the soil surface.
The heavy marine clay underlies most of the site at elevations above 18' msl. The upper
elevation for this heavy layer is —24 feet above msl for borings 1, 2, 3, 4, 5, 8 and 9. The
lower limit of the heavy layer extended approximately 72 inches depth and will be
determined by excavation. This heavy clay layer was evaluated for saturated hydraulic
conductivity.
The area described in borings 6 and 7 occurs below the 24'msl elevation. Sediments in
this area were loamy were also evaluated for saturated hydraulic conductivity.
Saturated hydraulic conductivity measurements were performed with a compact
constant head permeameter at selected hand auger borings. A compact constant head
permeameter (CCHP) was used to determine the saturated hydraulic conductivity of the
Slormwater Soil Report

soil. The compact constant head permeameter was set to run at a depth of 36"-in two
locations for a total of 2 measurements. The hydraulic conductivity was calculated
utilizing Glover's solution to Richard's equation for a shallow well pump in test for all data
points that met required assumptions and test parameters, as indicated by the CCHP
product manufacturer. Details of the methodology are described in Methods of Soil
Analysis, Part 1 and Compact Constant Head Permeameter: A Convenient Device for
Measuring Hydraulic Conductivity. Data was reported for all evaluations that complied
with necessary site testing assumptions as described by the manufacturer for use of this
device.
The heavy marine clay layers for borings 1, 2, 3, 4, 5, 8 and 9 were evaluated and
showed average saturated hydraulic conductivity for 24' msl elevation is 0.00058 in/sec.
The loamy marine layers for borings 6 and 7 were evaluated and showed average
saturated hydraulic conductivity for 18' msl elevation is 0.0023 in/sec. Atterberg limits
showed the plasticity index of 44 for this heavy clay material.
The lower depth of the heavy clay layer occurs at or above 18' msl elevation. This
material excavated from stormwater ponds should be stockpiled for lining stormwater
ponds. The portion of the proposed stormwater pond located at the rear of the property
is shown to be below this 18" msl contour. These portions of this pond will need to be
lined with the stockpiled material.
Recommendations:
It would be our recommendation to utilize the natural soil in place for the sidewalls of the
proposed stormwater pond located near the front of site and situated at the 26' elevation.
During excavation, this heavy clay horizon should be stockpiled for use as a pond liner.
The in situ clay sidewall of the pond will prevent lateral groundwater movement. We
recommend a clay key be installed beginning one foot below the upper limit of the clay
horizon, approximately 23' msl, and brought to within one foot of the soil surface. Site
construction excavation will reveal the actual lower limit of the clay. Below the lower limit.
of the clay layer, placement of a minimum thickness of one foot of a clay liner extending
at least one foot below the permanent pool should preclude lateral water flow into or out
of the pond.
It would be our recommendation to utilize the natural soil in place for the sidewalls of the
proposed stormwater pond located near the rear of site and situated above the 18'
elevation. Portions of the pond without the heavy clay sidewall should utilize the
placement of a minimum thickness of one foot of a clay liner extending at least one foot
below the permanent pool to preclude lateral water flow into or out of the pond. These
portions of the pond using liners should terminate the liner within three feet of the top of
the pond. Buried clay keys should begin four feet below the top of the pond and be
brought to within one foot of the soil surface.
Stormwater Soil Report

In summary, LMG has performed site specific evaluations within the stormwater pond
area. Elevation 18' has soils that will require clay liners and buried keys Elevation 26'
has soils that may utilize heavy clay soils in -place and augment with clay liners where
these heavy clay soils are not present. Please do not hesitate to contact me if you have
any questions with this report. I may be reached at 910-452-0001 or at

discontinuous and ranges from 15 to 75 percent of the E/Bh horizon. Weakly to strongly cemented Bh
concretions range from 15 to 35 percent of the Bh portion of this horizon. In some pedons the Bh
horizon is destroyed by tillage but the Bh concretions remain in the plow layer as evidence of this
horizon.
The E' horizon, where present, has hue of 1 OYR to 5Y, value of 5 to 8, and chroma of 2 to 4. The A, E,
and E/Bh horizons are loamy fine sand, fine sandy loam, loamy sand, and sandy loam.

GEOGRAPHIC SETTING: Onslow soils are on slightly convex interstream divide�in.the lower
Coastal Plain. Slopes range from 0 to 3 percent. They formed in loamy Coastal Plairi sediments at'
elevations of about 20 to 65 feet above sea level. Average annual precipitation is about So inches and
mean annual temperature is 63 degrees F. near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing series, these are the
Autryyille Echaw, Lenoir, Lynchburg, Pactolus, Rains, Stallings, and Wrightsboro series. Except for
the Echaw, none of the soils have a spodic horizon. Echaw soils are sandy and have a continuous spodic
horizon at a depth of 30 to 50 inches.
DRAINAGE AND PERMEABILITY: Moderately well drained and somewhat poorly drained; slow
runoff; moderate permeability. The seasonal high water table is about 18 inches below the surface for 2
to 4 months in most years.
USE AND VEGETATION: About 2/3 of the acreage is cleared and used for crops, pasture, or urban.
Main crops grown are coin, soybeans, and tobacco. Native woodland species include loblolly pine,
longleaf pine, red oak, white oak, water oak, hickory, sweetgum, red maple, holly, dogwood, and
sweetbay.
DISTRIBUTION AND EXTENT: Lower Coastal Plains of North Carolina, South Carolina, Virginia,
and possibly Georgia and Florida. The series is inextensive.

Subject: Riverside Subdivision (Pert xmance Plan)
Dear Ms. Wolf,
In regular session on May 21, 2003, the County's Technical Review Committee (TRC) voted 4-0
to approve Riverside Subdivision for a total of233 lots as displayed on the preliminary site plan
submitted on May 14, 2003. Preliminary site plan approval of the project comes with the following
requirements:
I. With the size of the prgjcct directly impacting the County's Water supply system, your client Will
be responsible for increasing capacity to the system. Details concerning the increase capacity Will
need to be worked out With the County Fire Services and Engineering staff. County sewer
availability will be limited to 40 lots per final plat or per County Engineering criteria.
2. The entrance to the project beginning at the T intersection of Castle Hayne Road and North Kerr
Avenue and extending west into the project will be dedicated, platted, and constructed as a 60'
right of way. This segment of the road will also be designated as a "public" road.
3. All TIA requirements embraced by NCDOT and the City/County MPO will be constructed. A
completed and approved NCDOT Driveway permit will need to be submitted prior to final plat
approval.
4. A road stub will be created between lots 83 & 89.
5. The'I`RC granted your request to have private roads (for public use) within the project.
6. No gates, speed bumps, on street parking or obstructions will be allowed oil the private roads.
Attending the TRC meeting were TRC Chairman David Adams (Planning Board), Sam Burgess
(Planning Staff), Jim lannucci (County Engineering), Anthony Printz (WMPO) and Malt Davis (Fire
Services). Also, attending the meeting were Bobby Harris, Jane Daughtridgc, and Shawn Ralston
(Planning Staff), Matt Murphy, (SECOF) and you.
Riverside Subdivision will be valid as it preliminary site plan for two years. If final plats are not
submitted within the 24-month time limit; the plat must be resubmitted as a preliminary plan in
accordance with the Subdivision Ordinance. Otherwise, the preliminary plan approval shall become

y
DEC 1
3Y:___-
void. A preliminary plan extension may be granted by the TRC for 12 months prior to expiration. The
TRC may grant up to a maximum of two one-year extensions. In the Riturc, County sewer may serve
this project. However, due to the limited capacity of the County's wastewater treatment facilities, sewer
capacity may not exist. DEHNR wastewater sewer construction and operations permits and/or final plat
approval of sections may be withheld, i f in the opinion of the County Engineer, adequate sewer capacity
does not exist. Please also be advised that all other local, State and Federal regulations will be

In regular session on September 24, 2008, the County's Technical Review
Committee (TRC) approved your request to change the road segment in Riverside from
public to private (but for public use) clue to a confliet with the proposed right-of-way and
off site utilities. According to testimony by Mr. Malpass and Mr. Mills, this method is not
an acceptable practice for NCDOT taking the roads over for State maintenance. The vote
by the TRC was 4-0. Please be advised that no gates, on street parking, or speed bumps
will be permitted. All terms and conditions of original preliminary site plan approval will
remain in force. In addition, a completed and approved NCDOT Driveway permit will be
retluirecl prior to final plat approval. A notation on the preliminary and final plats will
also indicate that the roads are private but for public use. This language will also be
incorporated in the homeowner covenants prior to final plat approval.
Attending the meeting were Chairman Richard Collier (Planning Board), Sam
Burgess (Planning), Jim lannucci (County Engineering), and Anthony Prinz (City -County
WMPO). Also attending the meeting were Chris O'Keefe and Bobby Harris (Planning
staff), Sharon Huffman (County Legal), Bill Pinnix and Jim Bonsor (CFPUA), Jeff
Malpass (PE for the protect), Michael Mills(Attorncy), Jennifer Braswell (NHSWCD),
end you.
Please share this information with your client. Also submit 6 paper copies of the
revised map to our Planning Office for'rRC Chairman signature. Contact me if you have
questions at 798-7441.
