Purpose
' '
A major goal of pollution prevention efforts during project construction is to control soil
14 and pollutants that originate on the site and prevent them from flowing to surface waters of
the Commonwealth. The purpose of this SWPPP is to provide requirements for achieving
11, that goal. A successful pollution prevention program also relies upon careful inspection
and adjustments during the construction process in order to enhance its effectiveness.
III1
Scope
This SWPPP must be implemented when land disturbing activities begin on the site. This
1 SWPPP will be made available for public inspection upon public request on site during
I-e_. normal business hours for the term of the permit authorization for the site. The SWPPP
t ' Construction Site Notice as well as a copy of the DEQ Coverage Letter must be posted
conspicuously and readable from a public right of way at the job site.
1 ,_
This SWPPP primarily addresses the impact of storm rainfall and runoff on areas of the
ground surface disturbed during the construction process. In addition, there are
recommendations for controlling other sources of pollution that could accompany the
major construction activities. Permit coverage is terminated as of the date the lot is
transferred to a new owner,coverage under a new VPDES permit is obtained,or as of the
: date another Operator assumes control over portions of the site not stabilized. In these
situations, coverage under the permit terminates at midnight the date the Notice of
Termination(NOT)is filed. Where the Operator seeks to terminate coverage because the
site has reached fmal stabilization,termination will become effective upon concurrence by
, LIIII:./
the VSMP Authority, or after 60 days from the submittal of the NOT,whichever occurs
first.
i
` - Forms required to implementthe SWPPP are included in the Appendices to this document.

and quantity calculations proving the adequacy of this best management practice for
meeting regulatory requirements are provided in Appendix I.
if
V. STORM WATER POLLUTION PREVENTION MEASURES AND CONTROLS
A variety of storm water pollutant controls(Best Management Practices)are recommended for this
project. These controls are reflected in the Erosion and Sediment Control Plans enclosed herein as
Appendix G. Some controls are intended to function temporarily and will be used as needed for
1 pollutant control during the construction period. These include temporary sediment barriers such
as silt fencing, a rock construction entrance,and inlet protection measures. For most disturbed
areas,permanent stabilization will be accomplished by covering the soil with pavement,buildings,
other improvements, and/or vegetation.
i1„ A. Erosion and Sediment Controls
1. Short and Long Term Goals—All erosion and sediment control measures
have been selected, designed and are to be installed in accordance with the
A Virginia Erosion and Sediment Control Law and Regulations. The short
term goal of construction phase stabilization is to minimize the loss of
sediment to adjacent waters during construction. The long term goal is to
minimize the loss of sediment from the project once constructed by
permanent soil stabilization.
2. Soil Stabilization-The purpose of soil stabilization is to prevent soil from
leaving the site. In the natural condition, soil is stabilized by existing
vegetation. The primary technique to be used at this project for stabilizing
site soil will be to provide a protective cover of turf grass,pavement, other
improvements, or building over disturbed soil.
(a) Temporary Seeding—Stabilization for all areas to remain denuded for a
1 Mai period of fourteen(14)days or longer(for disturbed area draining to
impaired waters, Tier III waters or to waters with a TMDL established
prior to the issuance of the Construction General Permit), or;thirty(30)
days or longer(for all other disturbed areas)shall be initiated within
twenty-four(24)hours after construction activity ceases in these areas.
The methods for establishing stabilization shall be applied within seven
w Crozet Avenue North Sidewalk Improvements June 2014
' Storm Water Pollution Prevention Plan
KHA Job#113038016
1
1
(7)days of initiation. Temporary seeding shall be in conformance with the
project plans and/or erosion and sediment control narrative.
(b) Permanent Seeding or Sodding-Stabilization for all areas at final grade
shall be initiated within twenty-fours (24)hours of completion of the land
disturbing activity.The methods for establishing final stabilization shall
be applied within seven(7)days of initiation. Except for small level
h spots, seeded areas shall be protected with mulch. Permanent seeding or
1 Sodding shall be in conformance with the project plans and/or erosion and
sediment control narrative.
r
(c) Structural Controls—Storm water runoff is to be structurally controlled
as depicted on the plan sheets and/or project narrative. Structural controls
shall be keyed to land disturbing activities especially on sites with
significant topography and shall be completely installed prior to
commencement of such land disturbing activities.
(d) Final Stabilization—Final stabilization is not considered established until
a ground cover is achieved that is uniform,mature enough to survive and
j3 will inhibit erosion. The Operator shall stabilize all exposed earth areas
with permanent vegetation as described in the project plans and/or erosion
and sediment control narrative.
B. Stormwater Management Controls
1. The following stormwater management controls have been utilized on this
project(mark appropriate activities and provide a brief explanation of each.
plans project f
Reer toas appropriate):
Dry ponds
❑ Stormwater retention/detention structures
❑ Flow attenuation from swales and natural depressions
❑ Infiltration of site runoff
❑ Bio-retention systems
I ❑ Stormwater wetlands
❑ Water quality structures
❑ Other measures(Specify)
C. Construction Phase"Best Management Practices"
Control of sediments has been described previously. Other aspects of this SWPPP are
listed below:
Crozet Avenue North Sidewalk Improvements June 2014
Storm Water Pollution Prevention Plan
KHA Job#113038016
1. Dust Control-Construction traffic must enter and exit the site at the stabilized
construction entrance. The purpose is to trap dust and mud that would otherwise be
carried off-site by construction traffic.
Dust control shall be provided by the Operator in compliance with applicable local and
state dust control regulations. After construction,the site will be stabilized(as
1 described elsewhere),which will reduce the potential for dust generation.
a 2. Effluent from de-watering activities must be filtered or passed through an approved
sediment trapping device, or both,before being discharged from the site.No
contaminated effluent or groundwater may be discharged with stormwater without a
separate VPDES discharge permit from the VDEQ. Such permit shall be obtained by
the Operator,prior to discharge.
3. Solid Waste Disposal-No solid materials, including building materials, are allowed to
1 be discharged from the site with storm water. All solid waste, including disposable
materials incidental to the major construction activities,must be collected,removed
I from the site and disposed of in a legal manner. The locations of solid waste
I containers must be shown on the site maps.
Substances that have the potential for polluting surface water and/or groundwater
1 must be controlled by whatever means necessary in order to ensure that they are not
Idischarged from the site. As an example, special care must be exercised during
t equipment fueling and servicing operations. If a spill occurs,it must be contained and
„
3; disposed of so that it will not flow from the site or enter groundwater, even if this
requires removal,treatment,and disposal of soil. In this regard,potentially polluting
substances should be handled in a manner consistent with the impact they represent.
1 4. Sanitary Facilities-All personnel involved with construction activities must comply
with state and local sanitary or septic system regulations. Temporary sanitary
facilities where provided at the site throughout the construction phase must be utilized
J, by all construction personnel and shall be serviced by a commercial operator when
provided. Their location must be shown on the project site maps if installed on site.
,0, 1
5. Water Source-Non-storm water components of site discharge must be clean water.
Water used for construction, which discharges from the site,must originate from a
14 public water supply or private well approved by the Virginia Department of Health.
Water used for construction that does not originate from an approved public supply
must not discharge from the site. It is to be retained in ponds until it infiltrates and
it evaporates.
D. Construction Phase"Best Management Practices"
During the construction phase,the Operator shall implement the following measures where
appropriate:

j ry,.
i L▪ ,
1. Material resulting from clearing and grubbing shall be stockpiled up slope from
n adequate sedimentation controls or hauled off-site.All soil stockpile areas shall
i g be annotated on the project plans in Appendix G.
2. All soil stockpile areas shall be maintained sufficiently far from water bodies
5 or wetlands and shall be adequately protected from erosion to preclude
3 migration of sediments into the water bodies or wetlands.

3. The Operator shall designate areas for equipment cleaning,maintenance,and
i IN repair. The Operator and subcontractor(s)shall utilize those areas. The areas
4 shall be protected by a temporary perimeter berm or silt fencing.
-i,.. i 4. Use of detergents for large scale washing is prohibited(i.e.,vehicles,buildings,
1 pavement surfaces, etc.)
33
.,..: L---
5. Chemicals,paints, solvents, fertilizers,and other toxic material must be stored
in waterproof containers. Except during application,the contents must be kept
locked in trucks or within locked storage facilities. Runoff containing such- L
material must be collected,removed from the site,treated, and disposed at an
approved solid waste or chemical disposal facility.
6. All materials used for concrete mixing shall be washed down in a designated
area where the corresponding runoff is directed into a leak-proof container or
3341 leak-proof settling basin. This concrete wash water shall be properly disposed
of off--site.
I VI. LOCAL PLANS
'1 i In addition to this SWPPP, construction activities associated with this project must comply with all
3 additional requirements set forth by the Town of Crozet.
,
VII. INSPECTIONS AND SYSTEM MAINTENANCE
A
The purpose of site inspections is to assess performance of pollutant controls. The inspections
A Li shall be conducted by the Operator's designated E&S inspector. If deficiencies in the erosion and
sediment control measures are determined,they shall be recorded on the inspection form by the
4Operator and corrective action shall be initiated by the Operator within the time frame specified
-..'.• L▪ ; below.
i I Between the time this SWPPP is implemented and final site stabilization is achieved, all disturbed
311 areas and pollutant controls must be inspected at one of the two frequencies below:

❑ At least once every five business days and no later than 48 hours following a measurable storm
event. In the event that a measurable storm event occurs when there are more than 48 hours
, k between business days,the inspection shall be conducted on the next business day.
Based on these inspections,the Operator shall decide whether it is necessary to modify this
,, ,,
SWPPP,add or relocate sediment barriers, or institute other actions required in order to prevent
pollutants from leaving the site via storm water runoff. The Operator has the duty to repair,
1 modify,maintain,or supplement pollutant control measures and take other actions necessary to
',., L achieve effective pollutant control
The Operator may install a rain gauge at the site to determine site specific rainfall conditions or
must provide estimates of rainfall at the project site and provide information as to how the
estimates were generated. For purposes of permit compliance,it is strongly recommended that
1• L
4 the Operator install a rain gauge at the project site.
Li
Examples of particular items to be evaluated during site inspections are listed below. This list is
not intended to be comprehensive. During each inspection, the Operator's inspectors must evaluate
f overall pollutant control system performance, as well as the effectiveness of system components.
Additional factors should be considered as appropriate to the circumstances.
1 A. Locations where vehicles enter and exit the site must be inspected for evidence of off-site
sediment tracking. A stabilized construction entrance will be constructed where vehicles
4 enter and exit. This entrance will be maintained or supplemented as necessary'to prevent
i sediment from leaving the site on vehicles. Sediment tracked onto public roadways must
be shoveled or swept from the roadway and re-deposited on site in a manner that minimizes
its offsite release potential.
--..,-,i LB. Sediment barriers must be inspected and, if necessary,they must be enlarged or cleaned in
order to provide additional capacity. All material excavated from behind sediment barriers
el shall be stockpiled on the up slope side of the barrier. Additional sediment barriers must
be constructed as needed. Sediment must be removed from sediment traps and sediment
iL-. basins when the design capacity has been reduced by 50%.
u C. Inspections will evaluate disturbed areas and areas used for storing materials that are
' I exposed to rainfall for evidence of, or the potential for,pollutants entering the drainage
i system. If necessary, the materials must be covered or original covers must be repaired or
1 supplemented. Also,protective berms must be constructed,if needed,in order to contain
runoff from material storage areas.
O• 001/4-
31 Grassed areas will be inspected to confirm that a healthy stand of grass is maintained. The
site has achieved final stabilization when turf grass cover provides permanent stabilization
--1, g of the soil surface exclusive of areas that have been paved or covered by building(s).
Permanent stabilization is not considered established until a ground cover is achieved that
33, L0, is uniform,mature enough to survive and will inhibit erosion.
D. All discharge points must be inspected to determine whether erosion control measures are
effective in preventing impacts to receiving waters.

v
Based on inspection results,any modification necessary to increase effectiveness of this'SWPPP to
an acceptable level shall be made by the Operator within seven calendar days of the inspection. All
modifications to the SWPPP document and approved plan will be noted on the construction plans.
The inspection reports must be completed entirely and additional remarks shall be included if
needed to fully describe a situation. An important aspect of the inspection report is the description
of additional measures that need to be taken to enhance plan effectiveness. The inspection report
must identify whether the site was in compliance with the SWPPP at the time of inspection and
specifically identify all incidents of non-compliance.
Inspection reports will be kept on file by the Operator as an integral part of this SWPPP for at
least thirty six months following the month the Notice of Termination is filed with the VDEQ.
It is the responsibility of the Operator to ensure the adequacy of site storm water pollutant
discharge controls. Physical site conditions,weather conditions or Operator practices may make it
necessary to install more structural controls than are shown on the plans. (For example,localized
concentrations of runoff could make it necessary to install additional sediment barriers.) Assessing
the need for additional controls and implementing them or adjusting existing controls are key
aspects of the effectiveness of this SWPPP until the site achieves final stabilization. Should a
control fail,be bypassed or otherwise be ineffective in maintaining sediments onsite and releasing
jIII sediment offsite the Operator will provide notification to the VDEQ in accordance with Part III. G.
of the VPDES Storm Water General Permit, as necessary.
If it is determined by the Operator's Inspector that there has been an upset or bypass of the control
A measures resulting in a release of sediment to State waters,the Operator's Inspector shall report
the bypass or upset to the Valley Regional Office of the Virginia Department of Environmental
j Quality(VDEQ)at 540-5747800 within 24 hours of discovery of the unanticipated bypass or
upset.
Within five days of making the verbal report to VDEQ,a written report shall be submitted by the
Operator containing:
• A description of the nature and location of the discharge;
• The cause of the discharge;
• The date on which the discharge occurred;
• The length of time that the discharge continued;
• The volume of the discharge;
• If the discharge is continuing,how long it is expected to continue;
g A
r. • If the discharge is continuing,what the expected total volume of the discharge will be; and
Any steps planned or taken to reduce,eliminate and prevent a recurrence of the present
•
discharge or any future discharges not authorized by this general permit.

N. Effect of a state permit. This general permit does not convey any property rights in either
fi real or personal property or any exclusive privileges, nor does it authorize any injury to private
I property or invasion of personal rights, or any infringement of federal, state or local law or
regulations.
j O. State law. Nothing in this general permit shall be construed to preclude the institution of
any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties
established pursuant to any other state law or regulation or under authority preserved by § 510
of the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III
U) and "upset" (Part III V), nothing in this general permit shall be construed to relieve°the
operator from civil and criminal penalties for noncompliance.
P.Oil and hazardous substance liability. Nothing in this general permit shall be construed to
preclude the institution of any legal action or relieve the operator from any responsibilities,
liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14
through 62.1-44.34:23 of the State Water Control Law or§ 311 of the Clean Water Act.
Q. Proper operation and maintenance. The operator shall at all times properly operate and
maintain all facilities and systems of treatment and control (and related appurtenances), which
are installed or used by the operator to achieve compliance with the conditions of this general
permit. Proper operation and maintenance also includes effective plant performance, adequate
funding, adequate staffing, and adequate laboratory and process controls, including appropriate
quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems, which are installed by the operator only when the operation is
necessary to achieve compliance with the conditions of this general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of
treatment or management of pollutants shall be disposed of in a manner so as to prevent any
pollutant from such materials from entering surface waters and in compliance with all applicable
state and federal laws and regulations.
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in
violation of this general permit that has a reasonable likelihood of adversely affecting human
health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in
an enforcement action that it would have been necessary to halt or reduce the permitted activity
in order to maintain compliance with the conditions of this general permit.
g U. Bypass.
1. "Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste
streams from any portion of a treatment facility. The operator may allow any bypass to
occur that does not cause effluent limitations to be exceeded, but only if it also is for
Page 26 of 29
9VAC25-880 (adopted 12/17/2013 published 2/24/2014 - effective 7/1/2014)
I AAA,

essential maintenance to ensure efficient operation. These bypasses are not subject to
the provisions of Part III U 2 and 3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the
operator shall submit prior notice to the department, if possible at least 10 days
i before the date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass
4as required in Part III I.
c 3. Prohibition of bypass.
,41 a. Except as provided in Part III U 1, bypass is prohibited, and the board or
department may take enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe
property damage. Severe property damage means substantial physical damage to
1 .--,-iproperty, damage to the treatment facilities that causes them to become inoperable,
' L.
or substantial and permanent loss of natural resources that can reasonably be
expected to occur in the absence of a bypass. Severe property damage does not
1 mean economic loss caused by delays in production;
L'i
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary
l treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
' L equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that occurred during normal periods of equipment
downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
' L
,-!.. I b. The department may approve an anticipated bypass, after considering its adverse
} effects, if the department determines that it will meet the three conditions listed in
Part III U3a.
V. Upset.
3
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which
i' ti4 there is unintentional and temporary noncompliance with technology-based state permit
effluent limitations because of factors beyond the reasonable control of the operator.An
upset does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities, lack of
E preventive maintenance, or careless or improper operation.
2. An upset constitutes an affirmative defense town action brought for noncompliance
with technology-based state permit effluent limitations if the requirements of Part III V 4
are met. A determination made during administrative review of claims that
1 noncompliance was caused by upset, and before an action for noncompliance, is not' a
L. final administrative action subject to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error,
1 improperly designed treatment facilities, inadequate treatment facilities, lack of
preventative maintenance, or careless or improper operation.
,,,-, .,,, 4. An operator who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs or oth1L
er
v relevant evidence that:
a. An upset occurred and that the operator can identify the cause(s) of the upset;
I b. The permitted facility was at the time being properly operated;

9VAC25-880 (adopted 12/17/2013 -published 2/24/2014 - effective 7/1/2014)
I
' Ld
1
c. The operator submitted notice of the upset as required in Part III I; and
d.The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of
an upset has the burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee,
the VSMP authority, EPA, or an authorized representative of either entity (including an
authorized contractor), upon presentation of credentials and other documents as may be
required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located
or
; conducted,or where records must be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that must be kept under
the conditions of this general permit;ti
3. Inspect and photograph at reasonable times any facilities, equipment (including
z monitoring and control equipment), practices, or operations regulated or required under
thisgeneral permit; and
I 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit
compliance or as otherwise authorized by the Clean Water Act or the Virginia
Stormwater Management Act, any substances or parameters at any location.
For purposes of this section, the time for inspection shall be deemed reasonable during
- regular business hours, and whenever the facility is discharging. Nothing contained herein shall
make an inspection'unreasonable during an emergency.
3 X. State permit actions. State permits may be modified, revoked and reissued, or terminated
1 for cause. The filing of a request by the operator for a state permit modification, revocation and
reissuance, or termination, or a notification of planned changes or anticipated noncompliance
does not stay any state permit condition.
Y. Transfer of state permits.
- Li1. State permits are not transferable to any person except after notice to the department.
Except as provided in Part III Y 2, a state permit may be transferred by the operator to a
new operator only if the state permit has been modified or revoked and reissued, or a
minor modification made, to identify the new operator and incorporate such other
requirements as may be necessary under the Virginia Stormwater Management Act and
the Clean Water Act.
1,05
2. As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the
proposed transfer of the title to the facility or property;
b.The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and
k.,.-, liability between them; and
c. The department does not notify the existing operator and the proposed new
operator of its intent to modify or revoke and reissue the state permit. If this notice is
not received, the transfer is effective on the date specified in the agreement
:: .---.L mentioned in Part III Y 2 b.
3. For ongoing construction activity involving a change of operator, the new operator
shall accept and maintain the existing SWPPP,' or: prepare and implement a new
SWPPP prior to taking over operations at the site.

DRAINAGE
Project Description
The Crozet Avenue North Sidewalk Improvements Project consists of approximately
1100' of sidewalk and roadway improvements along Crozet Avenue (SR 810)between
St.George Avenue and Crozet Elementary School. These improvements in Crozet will
' provide better pedestrian access and storm water infrastructure. Crozet, Virginia is
`i located approximately 15 miles from Downtown Charlottesville,VA. Crozet's current
surroundings are rural but the 2002 Crozet Master Plan and new Downtown Crozet
al Zoning envision an urban downtown core by 2024.
Description of Existing Drainage Conditions
The section of Crozet Avenue between St. George Avenue and Ballard Drive is
surrounded by grass, low lying brush and large canopy trees. This roadway also
provides access to two single-family detached residences and the old and new Crozet
Elementary School buildings. There are two high points along Crozet Avenue that
impact this project, one is approximately 75' north of St. George Avenue and the
1 other is approximately 200' north of the elementary school entrance. The water that
collects between these high points flows into roadside ditches and eventually joins the
Parrot Branch flowing through a culvert beneath Crozet Avenue towards the east.
I North of the sag existing cross drains(VDOT CD-1) drain the porous aggregate
base-stone (21-B's) of the road and discharge into the ditches on either side. They do
not convey stormwater underneath the road.
I The site drains to one (1) main outfall point (Appendix B):
• A culvert located approximately 600' north of the Crozet Avenue-St.
George Avenue intersection. The culvert crosses beneath Crozet Avenue
Li- directing the Parrot Branch towards the east. The culvert will be extended
to accommodate the new sidewalk and landscape verge.
Adjacent Areas
The site is bordered by St. George Avenue to the south and Ballard Drive to the north.
wry
Soil Description
According to the Natural Resource Conservation service map the soils on site are all
L-; loam variations.
Critical Areas

Adjacent Projects Contributing to SWM in Crozet
Crozet Master Plan
£1
The Crozet Master Plan was adopted in 2002 by the County Board of
1• 11 Supervisors. The master plan envisioned a thriving and accessible downtown
Crozet environment supported by a main thoroughfare(Crozet Avenue)that
=• r
encourages economic vitality and healthy activity. The Master plan set forth
I suggested patterns for private development and recommended necessary
infrastructure. The plan had a downtown first priority with adjacent
neighborhood centers of appropriate scale. The plan stressed the importance of
1 Ili interconnection of streets,alternatives to access, and an outline of infrastructure
necessary to be constructed for the plan to be implemented. The plan also
incorporated diversity in population with affordable housing and a welcoming
climate. The plan is built upon a foundation of encouraging local small
businesses; as well as, an innate value of Crozet's natural and historic resources
• A that make the community of Crozet what it is today.
7 Downtown Crozet Rezoning Project
Following adoption of the Crozet Master Plan in 2002, the County with the help
of CP+D developed the first step towards implementing the recommendations of
the plan by beginning to investigate a new zoning designation for portions of
Crozet. In June 2008, the County Board of Supervisors approved the Downtown
Crozet Rezoning that established zoning requirements within the Downtown Core
to facilitate urban development with minimal or zero foot setbacks. The
Downtown Crozet Rezoning made the ideal of the Master Plan of a thriving
,,. commercial urban mixed-use downtown a reality.
4' Safe Routes to School Sidewalk Improvements Project
Vi The County has proposed a project to improve sidewalks in front of Crozet
g Elementary School adjacent to the northern limits of this project. Improvements
t include proposed curb and gutter,a storm sewer drainage system, and an
improved curbed entrance to the school.

EROSION CONTROL
Erosion and Sediment Control Measures
--'' k • Inlet protection will be used at all existing and proposed culverts and storm sewer
K inlets to reduce the amount of sediment carried into the storm sewer systems.
- L ■ Silt fence is used to reduce the sediment carried offsite by sheet flow.
-. ■ Outlet protection is used to reduce erosion at pipe outlets.
iiPermanent and temporary stabilization
` - The site will be stabilized by the ultimate development including paved
areas,
seeded areas and landscaped areas.
- Temporary stabilization will be used in accordance with MS-1.
' L
■ Soil stockpiles and Borrow areas.
- -' - Soil stock piles will be encircled with silt fence and temporary seeding will
',,, be perfoiuued if necessary.

!' PROPOSED DRAINAGE IMPROVEMENTS
, kOverview
a
The proposed onsite drainage design consists of a series of curb drop inlets and
' L
.-.,-,. - reinforced concrete and HDPE pipes which collect runoff from the site. This'proposed
pipe system routes stormwater runoff from the ground surface to the culvert that crosses
beneath Crozet Avenue. See E&S'Narrative above for descriptions. The- drop-inlet
a
openings were sized in using VDOT Drainage Manual methods in Chapter 8 and sump
: L inlet openings calculated using QHEC-12 design software.
i Drain age'structure 101-7 was designed to match the proposed structure location of the
future Safe Routes to School project( SRTS-002-834,M501, UPC 97189) adjacent to
this project. Storm sewer proposed with that project was considered in design and will
' L
tie in at proposed structure 101-7.
The pre-development drainage area is shown on Plan Sheet CG-l00 the post-
development drainage areas are shown on Plan Sheet CG-101 (both in Appendix B).

Methodology
11,, illi The proposed drainage system was designed to collect and convey the storm water runoff
for 2-year and 10-year storms. Existing and proposed topography are shown on the
3 proposed plan using 1' contours. Times of concentration for overland flow were
3 calculated using the Seelye chart. Times of concentration for channel flow were
calculated using the Kirpich chart. The curb inlet throat lengths were analyzed using
ng
Haestad Methods Flowmaster software to check the depth and spread during the 2-year
J storm.
The following is a summary of the drainage design parameters for the proposed
e• development.

1 MS-19 COMPLIANCE
rz
i Overview
The point described above and shown on the pre and post-development drainage maps
included in the Appendix were analyzed for compliance with the MS-19 Standards set
forth by the Erosion and Sediment Control Regulations. A summary of compliance
, ii calculations are included below.
Analysis Point#1
.,- ,..tg,T,i 11-6
Analysis Point#1 is located at the existing sump in Crozet Avenue approximately 600'
i north of the St. George Avenue intersection. The outfall is the Parrot Branch tributary.
..„,• LDrainage area E l in the existin condition(see Appendix g g pp B) drains to Analysis Point#1.
In the pre and post-development condition all project area drains to Analysis Point#1.
_g The combined pre and post development 2 year flows of these drainage areas area
summarized below:
" Total DA Area of Site 2-Year
Description 2-Year Flow
(Acres) (Acres) Velocity(fps)
Pre-Development 116.32 1.13 81.86 7.53
Post-Development 116.32 1.13 81.87 7.53
The velocity produced by the 2 year storm under both pre-development and post-
il development conditions is greater than the existing permissible velocity of 2.5 ft/s for
Sandy Loam as specified by Table 3.18B of the Virginia Erosion and Sediment Control
Handbook, 3rd Edition. The 6.2' deep channel that the culvert outfalls into is capable of
accommodating the depth of flow of 1.85' produced by the 2 year storm. Further the
improvements and construction of the storm sewer improvements do not alter the
computed headwater of the existing culvert.
WATER QUALITY
This project is not located within the Chesapeake Bay Preservation Area(CBPA). The
western limit of the CBPA is approximately Interstate 95. However, the project involves
more than 10,000 square feet of land disturbance,so water quality requirements are
applicable for coverage under a VSMP permit. Water Quality requirements are described
in the Virginia Stormwater Management Handbook. This project utili7ed performance-
based water quality calculations to'perfolni the water quality analysis.
The Applicable Area within this project's right-of-way is 1.13 acres. The pre-
development impervious area is 0.37 acres,meaning the pre-development impervious
cover is 33.0%. This is greater than statewide average land cover condition of 16%,
meaning this project falls under"Situation 3"and must reduce post-development
pollutant runoff to 10% less than the pre-development pollutant runoff. The pre-
development pollutant runoff load is 0.89 lb/yr,meaning post development pollutant
runoff must be reduced to 0.80 lb/yr. With the post-development impervious area being
0.49 acres, the post development pollutant runoff would be 1.13 lb/yr if no BMP is
utili7ed. To reduce the post-development pollutant load then, a BMP(s) must be able to
remove 0.33 lb/yr. The pollutant removal requirement of 0.33 lb./year will be purchased
Lfrom a nutrient bank. Water quality calculations are presented in Appendix D.
