Reference: Soil Scientist Investigation
Tyler's Ridge at Sandhills
Dear Mr. Sadler,
A site investigation has been conducted for the above referenced property, located on the
western side of NC Highway 22, Moore County, , North Carolina. The purpose of this
investigation was to provide a general characterization of the soils in the areas proposed for
stormwater management devices, including ' a determination of the depth to evidence of a
seasonal high water table. In -situ hydraulic conductivity testing was also conducted. All soil
determinations were made in accordance with the "North Carolina Stormwater Best Management
Practice Manual" and Administrative Code Section: I SA NCAC 2H .1000. The materials at the
site were described in accordance with the USDA Field 'gook for Describing and Sampling Soils.
This report represents my professional opinion as a Licensed Soil Scientist.
SOIL PROFILE DESCRIPTIONS
Soil profile descriptions were collected at the six locations indicated in Figure 1 and are
attached to this report. Hand powered soil auger borings were utilized to make observations.
Soil morphological characteristics indicating a seasonal high water table (SHWT) were not
observed in any of the soil profile descriptions within ten feet of the ground surface nor within
two feet of the proposed basin bottoms (Table 1). In soil borings 3 and 4, where the basin
bottom is proposed 13 feet below surface, the borings were extended to 16 feet below surface
with no evidence of a SHWT. The soils in all six boring locations were observed to be sandy
textured throughout, with loamy sand layers greatly predominating and occasional sandy loam
layers observed. Based_ on information provided. in the Moore County Soil Survey, all soil layers
...... .
are anticipated to permeate water at a rate greater than two inches per hour. In -situ testing was
conducted in the soil layers at the proposed basin depth and is described in the following section
"Hydraulic Conductivity Testing".

HYDRAULIC CONDUCTIVITY TESTING
Hydraulic conductivity testing was conducted using a Compact Constant Head
Permeameter (CCHP), specifically an Amoozemeter, by using the shallow well pump4n
technique as detailed in the user's manual. Hydraulic conductivity results can vary, even within
similar soils, depending on the temperature and composition of the water used, climatic
conditions, proximity of the test layer to the water table, and other factors. Therefore, the results
from one boring may not be indicative of the entire area,
Hydraulic conductivity tests were performed within the soil layers located at the depth of
the bottom of the proposed basins. A constant head of water was established within a 3 cm
radius bore hole, and readings were made of the rate of water flow from the meter until it
appeared that steady state had been reached. The Glover Solution was used to calculate the
hydraulic conductivity, where Ksat = A * Q; A = {sinh"i (Wr) - [(r/H)' + 1]12 + rIH)1(211W), Q
is the steady-state rate of water flow from the CCHP into the bore hole; H is the depth of water in
the bore hole; and r is the radius of the bore hole. Table 2 summarizes the result of the hydraulic
conductivity investigation. For detailed information about each test, please refer to the Ksat field
datasheets that are attached.

A facility fee is charged based on the "impact" of the development as determined by the land
use of a project. These fee revenues provide proportionate funds needed to improve thor-
oughfares and acquire open space to serve the affected area.
There are two general categories of facility fees: Thoroughfare Fees and Open Space Fee

High Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 21-1.1000 and S.L. 2006-246, 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 consisLent with the design criteria used to size the stormwater control facility.
rytw ye PG..,.,�c.=, Gte � 'Tyfeur��ye P1••aR1=,Lcc
acknowledge, affirm and agree by my signature below, that I will
cause the following 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 as issued by the Division of Water Quality under the
Stormwater Management Regulations.
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 varies 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.
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
1,2,3,4,&5 338,897sf
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.
Each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface
waters.
**50 foot for projects located in the 20 coastal counties.
8. 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.

Bioretention Operation and 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.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will betaken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it 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 will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall

Reference: Soil Scientist Investigation
Tyler's Ridge at Sandhills
Dear Mr. Sadler,
A site investigation has been conducted for the above referenced property, located on the
western side of NC Highway 22, Moore County, North Carolina. The purpose of this
investigation was to provide a general characterization of the soils in the areas proposed for
stormwater management devices, including a determination of the depth to evidence of a
seasonal high water table. In -situ hydraulic conductivity testing was also conducted. All soil
determinations were made in accordance with the "North Carolina Stormwater Best Management
Practice Manual" and Administrative Code Section: 15A NCAC 2H .1000. The materials at the
site were described in accordance with the USDA Field Book for Describing and Sampling Soils.
This report represents my professional opinion as a Licensed Soil Scientist.
SOIL PROFILE DESCRIPTIONS
Soil profile descriptions were collected at the six locations indicated in Figure 1 and are
attached to this report. Hand powered soil auger borings were utilized to make observations.
Soil morphological characteristics indicating a seasonal high water table (SHWT) were not
observed in any of the soil profile descriptions within ten feet of the ground surface nor within
two feet of the proposed basin bottoms (Table 1). In soil borings 3 and 4, where the basin
bottom is proposed 13 feet below surface, the borings were extended to 16 feet below surface
with no evidence of a SHWT. The soils in all six boring locations were observed to be sandy
textured throughout, with loamy sand layers greatly predominating and occasional sandy loam
layers observed_. Based .on information provided, in the, Moore County Soil Survey, all soil layers
are anticipated to permeate water at a rate greater than two inches per hour. In -situ testing was
conducted in the soil layers at the proposed basin depth and is described in the following section
"Hydraulic Conductivity Testing".

HYDRAULIC CONDUCTIVITY TESTING
Hydraulic conductivity testing was conducted using a Compact Constant Head
Permeameter (CCHP), specifically an Amoozemeter, by using the shallow well pump -in
technique as detailed in the user's manual. Hydraulic conductivity results can vary, even within
similar soils, depending on the temperature and composition of the water used, climatic
conditions, proximity of the test layer to the water table, and other factors. Therefore, the results
from one boring may not be indicative of the entire area.
Hydraulic conductivity tests were performed within the soil layers located at the depth of
the bottom of the proposed basins. A constant head of water was established within a 3 cm
radius bore hole, and readings were made of the rate of water flow from the meter until it
appeared that steady state had been reached. The Glover Solution was used to calculate the
hydraulic conductivity, where Ksat = A * Q; A = {sinh-t (Wr) - [(r/H)' + I]12 + r/H)/(2IIHZ), Q
is the steady-state rate of water flow from the CCHP into the bore hole; H is the depth of water in
the bore hole; and r is the radius of the bore hole. Table 2 summarizes the result of the hydraulic
conductivity investigation. For detailed information about each test, please refer to the Ksat field
datasheets that are attached.
