Executive Summary
Kernstown Crossing plans to construct a multi -featured veterinary and kennel facility on
4+ acres immediately adjacent to Route 11. The existing lot has no buildings on it..
Initial development of the HP Hood stormwater management facilities accounted for
development of this lot, and stormwater engineering for this project required only that
stormwater be properly conveyed to the HP Hood system.
Only the 10-year design storm has been included in this report. Previous work was done
by TRIAD Engineering to validate the capacity of the I-IP Hood system to successfully
control stormwater. These calculations have been included as Appendix B.
No permanent sediment basins or stormwater ponds have incorporated into this design.

I STORM WATER MANAGEMENT NARRATIVE
1.1 PROJECT DESCRIPTION
This project is defined as construction of a full service veterinary and kennel facility.
The area to potentially be disturbed is approximately 4.245 acres. However, the total area
necessary for storm water control is approximately 6.1 acres, as offsite stormwater from
an additional HP Hood lot crosses the Kernstown Crossing lot.
1.2 EXISTING SITE CONDITIONS
VEGETATIVE COVER The property is covered by intermittently maintained grasses.
There are no stands of timber. Please refer to Sheet C-3 of the construction plans for the
existing site conditions.
TOPOGRAPHY The topography is extremely flat, with an average slope of 2.3%. Slopes
near the Route 11 embankment are approximately 25%.
DRAINAGE PATTERNS The site drains toward the main HP Hood facility and the
existing stormwater facilities. There are no natural ponds on the site.
1.3 ADJACENT PROPERTIES & OFFSITE AREAS
The site is bounded on the south and east sides by I-IP Hood property developed as an
industrial facility. The site is bounded to the north by developed property owned by
Allegheny Power Company. The site is bounded to the west by Route 11. Offsite
borrowing is probable. E&S measures at the offsite source are the responsibility of the
contractor, and shall be coordinated with the County E&S Administrator.
1.4 SUMMARY
The hydrologic routing for post -developed conditions for the 10-year storm events as
computed by Hydraflow I Iydrographs is included in the calculations in Appendix A.
This model indicates that the 10-year storm sends 6.23 cfs into the Hood system.
2 ANALYSIS METHODS
It is inappropriate to utilize the Rational Method for large non -homogeneous areas. The
Kernstown Crossing site was broken into 13 separate sub -basins based on an evaluation
of slope and runoff coefficient. These basins were then combined to eventually reach the
total flow for the area. A graphic representation of the flow pattern is shown in the figure
below. The sketch shows the flow patterns for each sub -basin as it flows to create the
overall drainage pattern. In Hydraflow using the Rational Method, each individual sub -
basin's response appears as a simple peaked triangle. However, because each basin has a
different amplitude (flow in cfs) and period (time to concentration in minutes), the
combined response for the total area is an irregular curve. A more in-depth discussion of
the Rational Method is available in the Erosion and Sediment Control Handbook of the

LANDSCAPE ARCHITECTURE CONSULTANTS

Virginia Department of Conservation and Recreation and other sources. A plot of each
individual hydrograph is available in Appendix A. Note that this appendix contains a
plot of each "base" zone, and a plot of the combined zones where they enter each storm
structure. Also note that in some cases (e.g. Zone 1) the effect of the runoff is "delayed"
due to conveyance through a storm structure or combination with another downstream
zone.
2.1 POST -DEVELOPMENT CONDITIONS
A description of the sub -basins is given in the table below. Each sub -basin is as large as
possible given that each sub -basin must be dominated by one type of ground surface and
one overall slope. The accompanying figure shows the layout of the zones. Note that the
buildings are not included in these stormwater calculations. A complete rainwater
collection and reuse plan (for washdown water) is included in the Architectural Plans.

3 EROSION AND SEDIMENT CONTROL MEASURES
Unless otherwise indicated, all vegetative and structural erosion and sediment control
practices shown on the accompanying Plans and in the Erosion and Sediment Control
Narrative will be constructed and maintained according to the minimum standards and
specifications of the VIRGINIA EROSION AND SEDIMENT CONTROL
HANDBOOK.
4 CONCLUSION
The measures and strategies depicted herein and the accompanying Plans will reduce the
storm -water impact on both this development and the adjoining properties. The existing
storm -water management basin will capture all flow from developed areas. Drainage on
site will be controlled by use of pavement, slopes, culverts, and overland channels
designed in full accordance with engineering practice and the laws and ordinances of the
state of Virginia and Frederick County.

' Included in this section are the supporting calculations for the storm water control basin.
In order to minimize soil disturbances, the sediment control basin has been utilized as the
storm water control basin. Additionally, the sediment control riser has been utilized as
' the storm drainage riser. The perforated plastic tube shall be removed and the 6" orifice
drilled out to a fill 12".
' One important note in the design of the storm water pond is to realize the impact of the
exit culvert's invert. An invert of 466.94' mandates a freestanding body of water in the
basin of nearly 3' depth. However, as the calculations in this report show, the basin has
' ample volume to contain a 100-year storm above this elevation. This is also why the
storage graphs begin at the 466.94' elevation.
' Given the nature of the existing topographical features in the vicinity of the proposed
basin, an emergency spillway is not provided. The basin is sized to adequately detain the
100-yr storm event without overtopping the earthen berm.

This narrative describes the erosion and sediment control measures to be constructed at
the proposed site located at the intersection of US Route 11 and Hood Way near Kernstown in
the County of Frederick, Virginia.
Project Description
The project consists of construction of entrance, parking, storm culverts, and other
associated items associated with the proposed business development. The property to be
developed is approximately 4.245 acres.
Existing Site Conditions
Vegetative Cover — The property is covered by intermittently maintained grasses. There are no
stands of timber. Please refer to Sheet C-3 of the construction plans for the existing site
conditions.
Topography — The topography is extremely flat, with an average slope of 2.3%. Slopes near the
Route 11 embankment are approximately 25%.
Drainage Patterns — The site drains toward the main HP Hood facility and the existing
stormwater facilities. There are no natural ponds on the site.
Adiacent Properties
The site is bounded on the south and east sides by HP Hood property developed as an
industrial facility. The site is bounded to the north by developed property owned by Allegheny
Power Company. The site is bounded to the west by Route 11.
Soils
According to the Frederick County Soil Survey prepared by the Soil Conservation
Service, the site sits on soil type 7C (Carbo-Oaklet-Rock Outcrop Complex). Erosion hazard
on this soil type is severe, and care was taken in the preparation of this E&S Plan and Narrative.
Bedrock occurs at depths to approximately 26 inches, and depth to bedrock is the primary
limitation to development in this soil type.
' Critical Erosion Areas
There are no critical erosion areas on the site. As always, points of concentrated flow
could present problems and are dealt with via outlet protection measures.
Erosion and Sediment Control Measures
Unless otherwise noted, the structural and vegetative practices shall be constructed and
maintained according to the Minimum Standards of the Virginia Erosion and Sediment Control
Law, Regulations and Certification Regulations and Specifications outlined in the latest edition of
the Virginia Erosion and Sediment Control Handbook.
The following summary(s) are for quick reference only and do not preclude any
requirements or standards listed in the Virginia Erosion and Sediment Control Handbook. Also,
other measures not specifically listed here or on the construction plans may be required to keep
the site within regulatory compliance during construction. The need for such items may not be
evident until the beginning of construction. The City Erosion and Sediment Control Administrator
will determine the need for additional erosion and sediment control measures.
STRUCTURAL PRACTICES
Temporary Construction Entrance - 3.02
One temporary construction entrance shall be constructed as shown on the Erosion and
Sediment Control Plan. The entrance shall be maintained in a condition that prevents
tracking or flow of mud onto public rights -of -way. This may require periodic top dressing
with additional stone or washing and reworking of existing stones as conditions demand
and repair and/or clean -out of any structures used to trap sediment. All materials spilled,
dropped, washed or tracked from vehicles onto roadways or into storm drains must be
removed immediately. During wet weather conditions, construction vehicle drivers will be
required to wash their wheels prior to entering the highway. During the washing process,
the contractor shall ensure that the runoff created by the washing process is passed
through one of the sediment removing devices such as a section of silt fence. Water for
washing operations shall be hauled to the site or shall be acquired from a hydrant
installed at the site. This hydrant shall be installed in accordance with the City of
Harrisonburg specifications. The use of water trucks to remove materials dropped,
washed or tracked onto the roadways will not be permitted under any circumstances.
2. Construction Road Stabilization - 3.03
Construction road stabilization shall be utilized wherever stone -based roads or parking
areas are to be constructed, whether permanent or temporary, for use by construction
traffic. Treated areas are likely to require periodic top dressing with new gravel. Seeded
areas adjacent to road and parking areas shall be check periodically to ensure a
vigorous stand of vegetation is maintained. Roadside ditched and drainage structures
shall be checked regularly to ensure they do not become clogged with silt or other debris.
3. Silt Fence Barriers - 3.05
Silt fence barriers shall be installed at locations shown on the Erosion and Sediment
Control Plan to filter sediment -laden runoff and decrease the velocity of sheet flows and
low -to -moderate level channel flows. Wire reinforcement shall be used for all silt fence
barriers.
4. Culvert Inlet Protection - 3.08
All culvert inlets shall be protected during construction in order to prevent sediment from
entering storm drainage systems prior to permanent stabilization of the disturbed area.
Inlet protection shall be provided for all culvert inlets as shown on the Erosion and
Sediment Control Plan.
5. Temporary Diversion Dike - 3.09
Temporary diversion dikes shall be constructed at locations shown on the Erosion and
Sediment Control Plan in such a manner to facilitate positive drainage to the Sediment
Basins and Sediment Traps. Temporary diversion dikes shall also be utilized to divert
storm run-off from upslope drainage areas away from unprotected disturbed areas and
slopes to a stabilized outlet. Upon termination of these dikes, positive drainage to the
outflow point shall be maintained.
6. Temporary Sediment Trap - 3.13
4
Two temporary sediment traps shall be constructed at the locations shown on the
Erosion and Sediment Control Plan and in accordance with the construction details
shown on the Erosion and Sediment Control Details. The temporary sediment traps shall
detain sediment -laden runoff from disturbed areas long enough to allow the majority of
the sediment to settle out.
7. Outlet Protection - 3.18
All storm pipe outlets shall be protected with a stone apron per specifications outlined in
the latest edition of the Virginia Erosion and Sediment Control Handbook. When
installed properly, outlet protection should require very little maintenance. However, it
shall be inspected periodically for scour from high flows. Care must be taken to properly
control sediment -laden construction runoff draining to the outlet protection until all up -
gradient areas have been fully stabilized.
8. Surface Roughening - 3.29
All areas in which grading takes place and a slope greater than or equal to a 3:1 slope is
constructed shall be surface roughened by stair step grading, grooving, furrowing, or
tracking.
9. Soil Stabilization Blankets and Matting - 3.36
LandLok TRM 435 matting or an approved equivalent shall be installed in all ditch
sections shown on the Erosion and Sediment Control Plan and in accordance with the
detail shown on the Erosion and Sediment Control Details.
10. Dust Control - 3.39
The contractor shall take measures to reduce the surface and air movement of dust,
which may present health hazards, traffic safety problems or harm animal and plant life
during land disturbing and construction activities.
GRASS ESTABLISHMENT
Topsoil Stockpile - 3.30
Topsoil shall be stripped from areas to be graded and stockpiled for future use. The
County Erosion and Sediment Control Administrator shall approve stockpile locations.
Stockpiles shall be temporarily seeded and protected with silt fence. When the topsoil is
spread over the graded areas, it shall be placed in 2-4 inch compacted lifts. Topsoil
hauled offsite shall be disposed of in an approved area as directed by the County
Erosion and Sediment Control Administrator.
Temporary Seeding - 3.31
The topsoil stockpiles and all areas to be rough graded during the course of the project
shall be immediately seeded with temporary vegetation upon completion of grading
operations. The appropriate seed mixture will be dependent upon the time of year it is to
be sown. The typical seed mixture specification is shown on the Erosion and Sediment
Control Details. The Erosion and Sediment Control Administrator must approve any
deviation from these mixtures.
NOTE:
Stabilization measures shall be applied to earthen structures such as dams, dikes,
diversions, and sediment basin embankments immediately after construction of the said
structure.
3. Permanent Seeding - 3.32
Permanent seeding shall be completed within seven days from achieving final grade of
the site.
' MANAGEMENT STRATEGIES
The following guidelines shall be utilized in the planning of construction:
' 1. Temporary diversion dikes, the temporary sediment traps, silt fence, the construction entrance
and other measures intended to remove sediment shall be constructed as a first step in the land
disturbing activity and shall be functional before up slope land is disturbed. These measures
shall also be stabilized with vegetation prior to up slope land disturbance.
' 2. The contractor shall install inlet protection and outlet protection for all storm utilities immediately
after installation of said structures to prevent sediment from collecting in the said structures and
being deposited down stream.
' 3. Construction shall be sequenced so that grading operations can begin and end as quickly as
possible.
I
4. Temporary seeding and other stabilization shall follow immediately after the site is stripped of
topsoil if it is determined that final grading will not begin within 30 days.
' 5. The developer shall be responsible for the installation and maintenance of all Erosion and
Sediment Control practices.
' 6. The topsoil stockpile location shall be immediately protected by silt fence on the downslope side.
NOTE:
The contractor shall install sediment trapping measures as the first step in construction.
' Once in place, the contractor shall strip topsoil and begin grading operations. The
contractor shall ensure that at the end of each working day all erosion and sediment control
measures are in place and functioning properly. This will be strictly enforced.
t These controls shall be in effect during the remaining development, which includes final
grading, utility construction, and paving.
CONSTRUCTION SEQUENCING NOTES:
The following construction sequence shall be utilized to ensure that the proper erosion and
' sediment control practices are in place and fully operational prior to upslope land disturbance.
Sequence"A"

2 — install Diversion Dikes and Silt Fence associated with Sediment Trap 2.
Permanent Stabilization
Permanent stabilization shall be applied to denuded areas immediately after final grade
is achieved on any portion of the site. Temporary soil stabilization shall be applied within seven
days to denuded areas that may not be at final grade but will remain undisturbed for more than
30 days. Permanent stabilization shall be applied to areas left dormant for more than one year.
Seeding shall be conducted in accordance with the latest edition of the Virginia Erosion and
Sediment Control Handbook. Permanently seeded areas shall be protected during
establishment with straw mulch. Hydro -seeding also requires straw mulch protection.
Maintenance
In general, all erosion and sediment control measures shall be checked daily
and after each rainfall. The following items shall be checked in particular:
The silt fence, diversion dikes, ns, inlet and outlet protection areas and temporary
construction entrances shall be checked for undermining, deterioration, and functioning
ability.
2. The sediment traps shall be checked regularly and after each significant rainfall to
determine the deposited silt. When sediment reaches the clean out level, it is to be
distributed back on the site in such a manner as to prevent further erosion.
3. All seeded areas shall be checked for adequate growth. If adequate growth is not evident,
the area shall be re -seeded to prevent the soils from eroding.
4. All temporary erosion and sediment control measures shall be removed only when
authorized by the City Erosion and Sediment Control Administrator.
5. Trapped sediment and the disturbed soil areas resulting from the removal of the temporary
measures shall be permanently stabilized to prevent further erosion and sedimentation.
6. Lonq term maintenance of all stormwater associated items is the sole responsibility of the
owner or a property owner's association.
Stormwater Management
Multiple stormwater management basins are utilized on this site to ensure
predevelopment flows rates are not exceed in final post development configuration.

ENGINEERING
Included in this section are the supporting calculations for the existing storm -water
management basin on the H.P. Hood property. For purposes of these calculations, the
basin utilized for this project will be designated as the North SWMB. For a more in-
depth analysis of the H.P. Hood site, refer to the H.P. Hood Engineering Calculations,
dated 27 June 2001, by Triad Engineering, Inc. This was approved by Joe Wilder on 8-
01-01.
The existing SWMB was designed to handle runoff from both the H.P. Hood site and
adjacent areas. The Kernstown Crossing site is contained in the North Roadway off -site
contributing area (see attached drainage divides map). The original calculations assumed
land parcels (totaling approx. 9.10 acres) on both sides of Hood Way to be fully
developed with a Rational runoff coefficient of 0.80, which is higher than that proposed
with the development of the Kernstown Crossing site. Additionally, the outfall from the
proposed storm sewer pipe entering the basin (733.00) is higher than the 25-year
maximum elevation of the basin (731.00). Given this fact, the SWMB is sized to
adequately and effectively convey the additional runoff from the Kernstown Crossing site
without any further modification.

RE: Review Comments for Site Plan 406-02, Kernstown Crossing

Dear Mr. Garber:
Thank you for the revised site plan of the above -referenced project. I have reviewed the plan, and offer
the following continents:
Caliper of Deciduous Trees. Please state what the caliper of the Hedge Maples Trees will be at
the time of planting. You have shown that the Iedge Maples will be planted between five (5) and
six (6) feet tall; however, all deciduous trees must be at least 2 inches caliper.
Paddock. Please remove the language "(not roofed)" from the paddock area. As discussed
previously, all animals must be kept within a filly enclosed structure.
Signature. Please remember to sign and seal the final copies of the site plan.
Please prepare a revision ofthis site plan, which adequately addresses all comments, and submit one copy
for my second review. Once all of the above issues are adequately addressed, and all other agency
comments addressed, the site plan should be ready for approval. Approved comment sheets are still
required from the following, agencies: the Virginia Department of Transportation (VDOT), the
Inspections Departrrrent, the Frederick County Fire Marshal, the Frederick County Health Department,
and the Frederick County Sanitation Authority.
Please do not hesitate to contact me, if you have any questions or concerns regarding this letter.

RE: 2nd Review Comments for Site Plan #06-02, Kernstown Crossing
Property Identification Number (PIN): 63-A-86C
Dear Mr. Garber:
In order to clarify what is required, the Department of Planning and Development is adding the review
comment shown below to the list that was provided to you on March 6, 2002. Please make note of this
comment and prepare an appropriate revision of the site plan.
Review Comments:
Category A Buffer. A Category A buffer is required against all property lines which adjoin
property zoned M2. A Category A buffer requires 50 feet of distance. Since the kennel runs are
required to be indoors, they cannot be in the 25-foot inactive or the 25-foot active portion of the
required buffer. The equine facility/apartment must also be moved outside of this buffer.
Please prepare a revision of this site plan, which adequately addresses all comments, and submit one copy
for my re -review. Once all of the above issues are adequately addressed, and all other agency comments
addressed, the site plan should be ready for approval. Approved comment sheets are required from the
following agencies: the Virginia Department of Transportation (VDOT), the Inspections Department,
the Frederick County Engineer (Public Works), the Frederick County Fire Marshal, the Frederick
County Health Department, and the Frederick County Sanitation Authority.

RE: Review Comments for Site Plan W-02, Kernstown Crossing
Property Identification Numbers (PIN): 63-A-86C
Dear Mr. Garber:
I have had the opportunity to review the site plan that you prepared for the proposed veterinary facility named,
Kernstown Crossing, and I offer the following comments:
Review Comments
1) Proposed Extension of Hood Way. It is my understanding that the proposed extension of Hood Way is not
planned to be constructed with this project. With this being the case, please provide a narrative on the site
plan which explains the intent of the future road extension that is shown. Furthermore, please distinguish
the future extension from what is being proposed during Phase One of the development. I could easily look
at the plan as it is today and require that the owner construct the road extension prior to occupancy.
2) Hood Facility Entrance. If possible, show the future entrance and driveway for the Hood Facility after the
future road is constructed. Otherwise, please provide a statement to the effect that a site plan shall be
submitted for review and approval for the future road extension prior to construction.
3) Required Front Setback. You have labeled the front setback as 50 feet, but have drawn it at 35 feet from
the front property line. Please make the necessary changes to correct this discrepancy. The required front
setback for a B2 property is 50 feet, when adjoining a primary or arterial highway, and 35 feet when
adjoining a minor or collector street.
4) VDOT Blockade. I suggest that you show a blockade acceptable to VDOT at the end of the proposed

the time of planting, and the location of all trees and shrubs.
11) No Animals Permitted Outdoors. The Zoning Ordinance requires that all animals be kept indoors within
the B2 Zoning District for veterinary offices and other related animal speciality services. The outdoor,
kennel runs are not permitted unless they are fully enclosed and part ofthe primary structure. Please make
all necessary changes.
12) Utilities. Please show the location of the proposed electric connection and utilities. In addition, provide
a statement to the effect that all proposed utilities will be located underground.
13) Signs. Please provide a statement to the effect that all future signs are required to be permitted through

Re: Buffer Category "A"
To Whom It May Concern:
Triad Engineering is pleased to provide public comment regarding the interpretation of Frederick
County Code Section 165-37 "Buffer and Screening Requirements".
There has been some uncertainty regarding the most appropriate interpretation of the
requirements of Buffer Category "A" as described in Table (a) of subsection D.1. As noted on
this table Full Screen and Landscape Screen requirements are described by dashes ("-"), and No
Screen is described as having a total of 50 feet of buffer.
Triad interprets the dashes in Full Screen and Landscape Screen to be equivalent to 0 feet of
buffer distance based on the following observations:
1. Section 165-37.B.(1) explicitly states "The higher the level of screening provided, the
lower the level of distance buffer required". If No Screen has a distance requirement of
50 feet, then higher levels of screening must, as noted by the above section of ordinance,
have lower distance requirements.
2. Table (b) of subsection D gives buffer requirements between zoning categories. This
table clearly uses the dash symbol to indicate "not required". i.e. there is no buffer
requirement between two RP -zoned sites.
These points combine to clearly and without bias establish the meaning of the dash to be "0" or
"not required".
There are additional considerations that may be derived from the apparent intent of the
ordinance. A particular applicant, Kernstown Crossing, is required to provide Category A buffer
between a B-2 development and existing M-1 sites. This applicant proposes a Landscape Screen
in accordance with 165-37.B.(1), and in fact the proposed screen exceeds the minimum
requirements of this section of the ordinance. This screen will not only separate the new facility
from the existing M-1 lots, it will lower the energy required to heat and cool the applicant`s
building, it will slow storm water runoff, and it will provide visual relief in the context of the
larger industrial park —all appropriate goals in tine with the intent of the ordinance. Requiring a
minimum of 50 feet of distance buffer in all Category "A" situations removes any impetus on the
part of a developer to incur additional landscaping costs, and this is apparently contrary to the
larger goals of Frederick County. Accepting reduced or eliminated buffer distances in the Full
Screen or Landscaped Screen types encourages the establishment of "green strips", thereby
lowering the impact of development on the overall environment.

In summary, Triad believes that interpreting the dashes in Table (a) of Section 165-37.D.(1) to be
"0" or "not required" is both accurate and appropriate, and we urge Frederick County
Department of Planning and Development to do so.
Very Sincerely,
