Section B
3'Project Description
3d. Explain the purpose of the project.
The proposed project is to develop parcels 8667 -28 -0584 & 8667 -37 -0995 into a
manufacturing business park. The project.is divided,into two phases. The property will
remain under the ownership of Harley Enterprises with the lots being leased to
manufacturing type businesses.
3e. Describe the overall project in detail, including the type of equipment to be used.
The project is to develop the property,to include,several small manufacturing businesses.
The overall project has been divided into two phases. Phase Ixis 9 acres in size and
includes the grading of approximately 3 acres to fill the remaining 6 acres with five (5)
feet of fill material. A small manufacturing business is planned to build a 10,000 square
feet and 5,000 square feet building, in the northwest section of the property. The, business
will be accessed by anew driveway connection.located 185 feet west of the current
driveway. The new access is designed to accommodate tractor trailers; WB50; as well as
private vehicles. Phase L includes the removal of two existing culverts in the un -named
tributary to Beaverdam Creek, the stream restoration at these locations and' the placement
of a new 48" culvert to provide a new access across the un -named tributary. The entrance
as well as the interior connections are designed to accommodate WB50 vehicles. The
grading is being completed with excavators, dozer and dump trucks. The stream work
will be completed with excavators and hand tools.
Phase II of the,project will extend the access road to the east end of the property and
access the adjoining property owned by Harley Enterprises. The lot layout of phase Il is
still being planned. No businesses have been identified at this time for phase II.
6 Future Project Plans
..
Phase I will include the construction of 514' of roadway, two buildings with parking
areas. The manufacturer will employ,less than 20 people at this location. Phase II will
extend the roadway 1850' to the eastern end of the property. The lot details for Phase II
is still under development. The portion of the property south and to the east of the UT to
Beaverdam Creek will remain undeveloped.
Section D
1. Avoidance and Mitigation

Harley Enterpnses, LLC
la. Specifically describe measures taken to avoid or minimize the proposed impacts in
designing the project.
The property currently has 75' of stream impacts. A 40' culvert is located near ,the
western end of the property. This location is used to access the gas utility easement on
the property. The second.location is 35' of culvert for the current access to the property.
Measures taken to avoid and minimize the impacts include the location of the new access
and the total linear footage of impacts. The location of the new access road is designed
not only to accommodate the design vehicles but to safely access the property. The cross
section of the roadway is the minimum needed for the WB50.
To minimize the total number of linear feet of stream impacts, both of the existing
culverts will be removed and the stream will be restored. The required access by the
utility company will be granted along the new access road. Relocating the utility access
point will keep the total impacts at 70' which is less than the current 75' of total impact.
Ib. Specifically describe measures taken to avoid or minimize the proposed impacts
through construction techniques.
The water will be diverted around the construction site, enabling the culvert to be
constructed in the dry. The construction will not be scheduled immediately following a
rain event to avoid the potential for high water situation.
Section E.
2d. Storm water management ,plan
The storm water for phase I will be collected in one of four systems. The storm water
drainage from I40 and Beaverdam Road will be collected and carried to the UT by a new
24" culvert. The culvert will be constructed with drop inlets to access the pipe for
maintenance. Storm water from station 1 +60 to 3 +00 as well as storm water from the
impervious areas will be diverted through a storm water detention area. This detention
area consists of a Level Spreader — Vegetated Filter Strip and a Dry Detention Basin. A
bypass flow ditch is provided for stormwater exceeding the design flow. The bypass
flow ditch flows into the special sediment ditch. Storm water from,station 3 +00 to 5 +00
will be collected in grass lined ditches and then conveyed to the western edge of the
property in a special sediment ditch to be constructed along the northern property line.
Section F
4. Sewage Disposal
The septic system at the current house will be used until the house is removed. Once
removed, portable toilets will be used during the construction phase. The waste water for
the manufacturing facilities will be disposed from the property, by a new 8" gravity main
that will be connected to the municipal system located at the western end of the property.

How Soil Surveys
Soil surveys are made to provide information about the soils and miscellaneous areas
in a specific area They include a description of the soils and miscellaneous areas and
their location on the landscape and tables that show soil properties and limitations
affecting various uses. Sod scientists observed the steepness, length, and shape of
the slopes; the general pattern of drainage; the kinds of crops and native plants, and
the kinds of bedrock They observed and described many soil profiles. A sod profile is
the sequence of natural layers, or horizons, in a soil. The profile extends from the
surface down into the unconsolidated material in which the soil formed or from the
surface down to bedrock. The unconsolidated material is devoid of roots and other
living organisms and has not been changed by other biological activity
Currently, sods are mapped according to the boundaries of mayor land resource areas
(MLRAs). MLRAs are geographically associated land resource units that share
common characteristics related to physiography, geology, climate, water resources,
soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically
consist of parts of one or more MLRA
The soils and miscellaneous areas in a survey area occur in an orderly pattern that is
related to the geology, landforms, relief, climate, and natural vegetation of the area
Each kind of soil and miscellaneous area is associated with a particular kind of
landform orwith a segment of the Iandfoan By observing the soils and miscellaneous
areas in the survey area and relating their position to specific segments of the
landform, a soil scientist develops a concept, ormodel „of how they were formed Thus,
during mapping, this model enables the soil scientist�to predict with, a considerable
degree of accuracy the kind of soil or miscellaneous area at a specific location on the
landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented by
an understanding of the soil- vegetation- landscape relationship, are sufficient to verify
predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of,plant roots, reaction, and other features that enable them to
identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely, defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character of
soil properties and the arrangement of horizons within the profile. After the soil
scientists classified and named the soils in the survey area, they compared the
5

Custom Soil Resource Report
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that have
similar use and management requirements. Each map,und is defined by a unique
combination of sod components and /or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components of
the map unit. The presence of minor components in a map unft'in no way,diminishes
the usefulness or accuracy of the data. The delineation ofsuch landforms and
landform segments on the map provides sufficient information for the development of
resource plans. If intensive use of small areas is planned, onsite investigation is
needed to define and locate the soils and miscellaneous areas
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape, and
experience of the soil scientist. Observations are made to test and refine the soil -
landscape model and predictions;and to verify the classification of the soils at specific
locations. Once the soil- landscape model is refined, a significantly smaller number of
measurements of individual soil properties are made and recorded. These
measurements may include field measurements, such as those for color, depth to
bedrock, and texture, and laboratory measurements, such as those for content of
sand, sift, clay, salt, and other components. Properties of each soil typically vary from
one point to another across the landscape
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area.generally
are collected for laboratory analyses and for engineering tests. Soil scientists °interpret
the data from these analyses and tests as well as the field- observed characteristics
and the sod properties to determine the expected behavior of the soils under different
uses. Interpretations for all of the sods are field tested through observation of the soils
in different uses and under different levels of,management. Some interpretations are
modified to fit local conditions, and some new interpretations are developed to meet
local needs. Data,are assembled from other sources, such as research information,
production records, and field, experience of specialists. For,example, data on crop
yields under defined levels of management are assembled from farm records and from
field or plot experiments on the same kinds of soil.
Predictions about soil behavior are based not only on sod properties but�also on such
variables as climate and biological activity Soil conditions are predictable over long
periods,of time, but,they are not predictable from year to year. For example, soil
scientists can predict with a fairly high degree of accuracy that a given sod will have
a high water table within certain depths in most years, but they cannot predict that a
high water table will always be at a specific level in the sod on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and
identified each as a specific map unit. Aerial photographs show trees, buildings, fields,
roads, and rivers, all of which help in locating boundaries accurately.

Map Unit ®ascriptions
The map,unds delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas'in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
majorrkinds of soil or miscellaneous areas. A map unit is'identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits forthe properties of the soils. On the landscape,
however, the sods are natural,phenomena, and they have the characteristic variability
of all natural phenomena. Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if ever, can be mapped without including areas -of other taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of,the dominant sod.or soils in the
'map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and'behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, ordissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
10

Custom Soil Resource Report
where the pattern was so complexthat it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but ratherto separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments
on the map provides sufficient information for the development of resource plans. If
intensive use of small areas is planned, however, onsde investigation is needed to
define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions Each
description includes general facts about the unit and gives important soil properties
and qualities.
Sods that have profiles,that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other charactedsticsthat.affect their use On the basis of such
differences, a soil series is divided into soil phases Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha sift loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern,or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the sods or miscellaneous areas are somewhat similar in all
areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present or
anticipated uses of the map units in the survey,area, it was not considered practical
or necessary to map the sods or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat,similar Alpha -
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them. Alpha and Beta soils, 0 to 2 percent'slopes, is an example.
Some surveys include miscellaneous areas Such areas have little or no sod material
and support little or no vegetation. Rock outcrop,es an example.

This system (check one):
® does ❑ does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
- The drainage area will be managed to reduce the sediment load to the dry
extended detention basin.
- Immediately after the dry extended detention basin is established, the vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- No portion of the dry extended detention pond will be fertilized after the first
initial fertilization that is required to establish the vegetation.
- I will maintain the vegetation in and around the basin at a height of
approximately six inches.
- Once a year, a dam safety expert will inspect the embankment.
After the dry extended detention basin is established, it will be inspected once a quarter
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.

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 maintenance procedures-
- Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the ,growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut�shorter than 3 to 5 inches and
maybe allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if, necessary
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (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

Start -up Fertilizer Applica ton to the Engineered Filter
Strip Topsoil
(from NCSU Cooperative Extension Service 2008)
If Obtaining a Sod Test
Send approximately 1 cup of the air -dried sod
sample to the NC DA & CS Agronomic
Division Sod Testing Services, 1040 Mad
Service Center, Raleigh NC 27607 Boxes and
Forms can be obtained at your county
Cooperative Extension center or at the
Agronomic Division office in Raleigh Allow
several weeks for the results to be returned
Apply the amount of lime and fertilizer
recommended for your sod by the sod testing
laboratory For additonal nformaton about
interpreting a sod test, visit this Web site
http / /www ncagr coin /agronomi /uyrst htm
If No Sod Test is Obtained
Apply the following for grasses other than
centipede)
• 75 Ibs of ground limestone per L000 sq Ft
▪ A starter type fertilizer (one that is high in
phosphorus) based on the type of grass and
the planting method Fertilizer bags have a
three- nunber' system indicating the primary
nutrients, such as 8 -8 -8 or 5 -10 -10 These
numbers denote the N -P -K ratio —the
Percentage of each nutrient in a fertilizer The
percentages are noted in the following order
N Nitrogen For green color and growth
P205 Phosphorus For good rooting
K20 Potassium to enhance pest and
environmental stress tolerance
Common examples of starter fertaaers required
For a 1,000 sq ft area nctude 40' Dos of 5-10 -10, 20
Ibs of 10- 20 -20, or 16 lbs of 18 -24 -6 For sandy
soils, typical to the Coastal Plain and Sandhills,
fertilizer rates should be increased by 20 percent
Note For centipede grass, apply 10 lb of nitrogen per
L000 square Feet Too much fertilizer
will kill centipede
