The Township has adopted a Subdivision and Land Development
Ordinance. In implementing that ordinance, the following standards
shall apply. In the event of conflict between that ordinance and this
code, the more-restrictive standard shall govern.
A. Township streets. Typical section of grading, paving, curbing, underdrains
and berm grading for Township streets shall be installed in accordance
with the construction standards on Standard Detail No. 2, Typical
Road Section (with shoulder), and Standard Detail No. 3, Typical Road
Section (with curb). Geometric design shall be in accordance with the appropriate
design speed as determined by the Township upon recommendation of
the Township Engineer and the design standards of the Township Code.
B. Materials. The base course and wearing surface of all streets shall
be constructed in accordance with the standards of this code, and
all materials used shall meet the latest Pennsylvania Department of
Transportation specifications. Additional base course depths may be
required as the Engineer may determine to be necessary for the type
of street that has been proposed.
C. Bituminous curb underdrain. Permanent underdrains of a size and slope
to be determined by the Township Engineer shall be installed on the
upper or higher side of all streets, in cut areas where they are necessary
to prevent the infiltration of water under the paved roadway and at
the low points in all roads or streets. All underdrains shall parallel
the roadway as nearly as possible and shall be in accordance with
the construction standards on Standard Detail Nos. 2 and 3.
D. Shoulders. Street shoulders shall be graded for the full width of
the right-of-way in accordance with the typical street section in
this code and thoroughly compacted by rolling all shoulders. Slopes
and berms shall be seeded to prevent erosion.
E. Utilities in streets. All utilities crossing streets shall be installed
in trenches backfilled and compacted with aggregate meeting the Pennsylvania
Department of Transportation specifications and approved by the Township
Engineer, and all other utilities within the right-of-way of streets
shall be installed before the base, binder and bituminous wearing
course is installed.
F. Trench repaving for bituminous paving. All pavement restoration in
bituminous pavement shall be constructed in accordance with the construction
standard in Standard Detail No. 4, Pavement Restoration.
G. Two-phase paving. When bituminous paving of a cartway is proposed
for a subdivision or other land development and it is anticipated
that construction activity and heavy material hauling will be taking
place for an extended period of time across said cartway, a one-half-inch-thick
skim coal of either FJ-1 bituminous material or other bituminous wearing
course material may be applied on a temporary basis, provided the
arrangement is properly spelled out in the developer's agreement.
After the heavy material hauling activity is complete, the final bituminous
wearing course material shall be installed on the cartway as specified
in the developer's agreement.
H. Curb ramps. The location and design of all curb ramps for access
by disabled persons shall be approved by the Township Engineer. Such
approval does not represent compliance with the Accessibility Guidelines
of the Americans with Disabilities Act. However, such compliance is
required.
I. Any opening of a Township road or street by any person, entity or
utility for any purpose shall require a street opening permit from
the Township and financial security as determined by the Township.
The Township has adopted a separate Stormwater Management Ordinance. In implementing that ordinance, the following standards
shall apply. In the event of conflict between that ordinance and this
code, the more-restrictive standard shall govern.
A. Storm sewer pipe. A minimum fifteen-inch-diameter pipe shall be installed
for all storm sewers to be maintained by the Township. The following
is a list of acceptable pipes for use in the Township:
(1) Reinforced concrete pipe (RCP), ASTM C76 Class III and Class IV.
(2) Corrugated polyethylene (PE) culvert pipe, AASHTO-M294 and Type S.
(3) Polyvinyl chloride (PVC) pipe, AASHTO-M304.
(4) Corrugated galvanized steel pipe AASHTO-M245, Type 1, AASHTO-M2465

(7) Pipe constructed using other materials may be considered, provided
said pipe is specified in PennDOT Form 408, latest edition, and approved
by the Township Engineer.
B. Stormwater inlets. Stormwater inlets located in the street paving
shall conform to the construction standard in PennDOT Publication
No. 72-M, Standards for Roadway Construction, Drawing No. RC-34M,
Type M Inlet. Stormwater inlets shall be placed at all low points,
at street intersections and at points along both sides of the street
to ensure adequate drainage, but in no case shall the distance between
stormwater inlets along the street exceed 300 feet unless approved
by the Engineer. Stormwater inlets at street intersections shall be
placed on the tangent and not on the curved portion. Additional inlets
shall be constructed in areas as may be directed by the Engineer during
construction to provide for proper control of surface water.
(1) Grates and frames shall be structural steel, bicycle-safe.
(2) Ladder bars. Plastic ladder bars shall be installed in all inlets
exceeding a depth of five feet and shall be in accordance with PennDOT
Publication No. 72-M, Standards for Roadway Construction, Drawing
No. RC-34M.
(3) A poured concrete invert shall be formed in the base of all inlets
to provide full drainage out of and through the structure.
C. Stormwater manholes. All manholes shall be precast concrete constructed
in accordance with the construction standards in PennDOT Publication
No. 72-M, Standards for Roadway Construction, Drawing No. RC-39M.
Manholes shall be installed at all changes in alignment and grades
of storm sewers as may be directed by the Engineer to provide for
proper maintenance. If maintenance is not a problem, pipe may be installed
on a curve, provided the deflection angle of the pipe joint does not
exceed the manufacturer's specifications. Inlets may be substituted
for manholes where approved by the Engineer. The maximum distance
between structures (inlets or manholes) shall be 300 feet, unless
otherwise approved by the Engineer.
D. Headwall/endwall and riprap. Concrete headwalls and splash aprons
shall be constructed in accordance with the construction standards
in PennDOT Publication No. 72-M, Standards for Roadway Construction,
Drawing Nos. RC-31M and RC-72M, at the outfall of all storm sewers.
E. Storm sewer lateral connection. All storm sewer lateral connections
shall be made in accordance with applicable law. All storm sewer lateral
connections shall be located at manholes, inlets or at locations approved
by the Township Engineer or his designated representative.
F. Township design requirements for stormwater management.
(1) General requirements.
(a)
The design criteria are intended to elaborate on the Township
Stormwater Management Ordinance and to complement the Pennsylvania
Stormwater Management Act, P.L. 864, No. 167.
[1]
Said act requires that actions be taken:
[a] To assure that the maximum rate of stormwater runoff
is no greater after development than prior to development activities;
or
[b] To manage the quantity, velocity and direction
of resulting stormwater runoff in a manner which otherwise adequately
protects health and property from possible injury.
[2]
Stormwater management design and construction will conform in
general to the applicable recognized national and state acts, manuals,
and references such as the Pennsylvania Stormwater Management Act
and PennDOT published forms.
(b)
All stormwater management plans shall be designed and certified
by individuals registered in the Commonwealth of Pennsylvania and
qualified to perform such duties.
(c)
Where applicable, stormwater management facilities shall comply
with the requirements of Chapter 105 (Dam Safety and Waterway Management)
of Title 25, Environmental Protection, of the Pennsylvania Department
of Environmental Protection (DEP), and Section 404 of the Clean Water
Act as authorized by the United States Corps of Engineers.
(d)
Stormwater management facilities that involve a state highway
shall be subject to the approval of the Pennsylvania Department of
Transportation.
(e)
Stormwater runoff from a project site shall flow directly into
a natural watercourse or into an existing storm sewer system, or onto
adjacent properties in a manner similar to the runoff characteristics
of the predevelopment flow.
(f)
Stormwater runoff shall not be transferred from one watershed
to another unless the watersheds are subareas of a larger watershed
that are tributary to a common point of interest within or near the
perimeter of the property. Transfer of runoff from one watershed to
another under any other circumstances shall only be approved at the
discretion of the Township. Documentation shall be provided that peak
flow rates are not increased following development and there will
be no detrimental impact in downstream areas.
(g)
All stormwater runoff flowing over the project site shall be
considered in the design of the stormwater management facilities.
(h)
For any stormwater management facility requiring a permit to
be issued by the DEP, said permit, along with a supporting report
and plans used to secure the permit, shall also be submitted.
(2) Stormwater management standards.
(a)
Design storms.
[1]
For developments larger than three acres, the SCS twenty-four-hour,
Type II, rainfall distribution shall be used for analyzing stormwater
runoff in predevelopment and post-development conditions, as well
as for designing runoff control facilities (except storm runoff collection
and conveyance facilities). For development sites less than three
acres, the Rational Method may be utilized to determine peak flows
and the Modified Rational Method used for design and routing of runoff
control facilities.
[2]
If the Rational Method is used, the Region No. 1, Pennsylvania
Rainfall Intensity — Duration — Frequency Chart shown
in the Pennsylvania Department of Transportation Design Manual, Part
2, most-recent version, shall be used to determine the rainfall intensity
in inches per hour.
(b)
Where, in the judgment of the Engineer/Township, the additional
volume of stormwater runoff associated with a proposed development
site will have a detrimental impact on downstream properties, and/or
an existing downstream flood problem is documented, post-development
peak flows may be required to be reduced to less than predevelopment
peak flows. Under these circumstances, acceptable peak flow rates
will be determined at the discretion of the Engineer/Township for
a given storm event(s) based on exiting downstream restrictions. Additional
hydrologic studies or analyses may also be required.
(c)
Calculation methods.
[1]
Development sites. For the purposes of computing peak flow rates, runoff hydrographs and storage requirements for development sites, either the SCS Soil Cover Complex Method as presented in the most-recent version of Technical Release 55 (TR-55) shall be used, or the Rational Method as specified in Subsection
F(2)(a). When the Rational Method is used, the technical data from the Pennsylvania Department of Transportation Design Manual, Part 2, most-recent version, shall be used to determine rainfall intensities, time of concentration, and runoff coefficients. The use of alternative hydrologic methodologies may be approved by the Engineer/Township if sufficient justification and documentation of their application is provided.
[2]
Stormwater collection conveyance facilities.
[a] For the purpose of designing storm sewers, open
swales and other stormwater runoff collection and conveyance facilities,
the Rational Method shall be utilized. Rainfall intensities for design
should be obtained from the Pennsylvania Department of Transportation
Design Manual, Part 2, most-recent version. The design storm for storm
sewers and swales that will discharge to detention facilities is the
one-hundred-year storm. The ten-year design storm for storm systems
discharging to detention facilities shall be acceptable, provided
it can be documented that runoff exceeding the ten-year capacity of
the storm system during a one-hundred-year storm event will ultimately
discharge to the detention facility by alternative means, without
endangering public safety or damaging private property. The design
storm for all other on-site storm sewers or swales is the ten-year
storm event, provided that larger storm events will not impact private
property. Calculation sheets must be submitted. For storm inlets with
multiple inflow pipes and/or bends where energy losses will be significant,
inlet control conditions at the entrance to the outflow pipe shall
be a design consideration to determine capacity.
[b] All stormwater collection and/or conveyance systems
routing water through or around the development site shall be designed
for the one-hundred-year storm event, unless it can be documented
that said facilities will not create a hazard. A drainage easement
shall be provided to contain and convey the one-hundred-year flood
event throughout the project site, beginning at the furthest upstream
property line of the proposed development in the watersheds.
[3]
Predevelopment conditions. The cover type for all sites will be considered to be woods with light underbrush in good hydrologic condition at the time of proposed development. All hydrologic parameters used to calculate peak flow rates shall use the appropriate coefficients pertaining to these conditions, as recommended in the hydrologic methodologies noted in Subsection
F(2)(c)[1].
[4]
Post-development conditions. The hydrologic parameters used
to develop peak flow rates shall be reflective of anticipated soil
runoff characteristics following grading and development of the site.
(d)
Stormwater management facilities. Peak runoff rates for all
areas within or impacting the project site shall be determined and
considered in the design of stormwater management facilities. These
calculations shall be based on land use, time of concentration and
other standard hydrologic parameters.
(e)
Allowable release rates. The allowable release rates from stormwater management facilities, or a development site in general, shall be less [as per Subsection
F(2)(b)] than or equal to the predevelopment peak runoff rates generated for the site. All stormwater runoff discharged from the site that is not controlled by a stormwater management facility shall be accounted for in the determination of the allowable release rates for the full range of storm events.
(f)
Joint development of control systems. Stormwater control systems
may be planned and constructed in coordination by two or more developments
so long as they are in compliance with this code.
(3) Stormwater management plan.
(a)
General requirements.
[1]
No final subdivision or land development plan shall be approved,
no permit authorizing construction issued, or any earthmoving or land
disturbance activity initiated until the final stormwater management
plan for the development site is approved in accordance with the provisions
of this code.
[2]
A letter from the Beaver County Conservation District (BCCD)
approving the erosion and sedimentation control plan must also be
received prior to the initiation of any grading. In the event that
submission to the BCCD is not required by the Township, an erosion
and sedimentation control plan prepared in accordance with the most-recent
version of PADEP Chapter 102, Erosion and Sedimentation Control Program
Manual, must be approved by the Township.
(b)
Stormwater management report. A written and bound report shall
be submitted including, but not necessarily limited to the following
information;
[1]
Proposed name or identifying title of project, the name and
address of the landowner and developer of the project site, as well
as the name, address, and phone number of the consultant who prepared

Copies of applications may be requested by the Township. All stormwater
or drainage-related computations or reports associated with these
permit applications shall be submitted to the Township for reference
and for review.
(g)
One-hundred-year floodplain delineation.
[1]
Stormwater management facilities located with or affecting the
floodplain of any watercourse shall also be subject to the requirements
of the Township Floodplain Management Ordinance, as amended from time
to time, which regulates construction and development within areas
of the Township subject to flooding.
[2]
The one-hundred-year floodplain must be delineated on all plans
for all watercourses which have a watershed area of 150 acres or greater.
Where, in the judgment of the Township, private property or public
facilities may be adversely affected by the proposed activity, the
one-hundred-year floodplain shall be established for any watercourse.
[3]
The one-hundred-year floodplain shall be delineated by one of
the following methods:
[a] The FIS study by the Federal Emergency Management
Agency (FEMA).
[b] A hydrologic report prepared by an individual registered
in the Commonwealth of Pennsylvania to perform such duties. Calculations
and channel hydraulic characteristics used to determine floodplain
limits shall be provided.
(h)
Municipal liability disclaimer. Approval of a stormwater management
plan by the Township shall not be construed as an indication that
said plan complies with the requirements, laws, or standards of any
agency of the commonwealth which may or may not govern said activity.
(4) Design criteria for stormwater detention basins. The following criteria
shall be utilized for the design of proposed detention basins:
(a)
All detention basins shall be equipped with outlet structures
to provide discharge control for the design storm events. Provisions
shall also be made for auxiliary structures that are capable of passing
the post-development one-hundred-year storm peak runoff flows, presuming
blockage of all lower flow controls, without damaging the basins.
(b)
Shared storage basins, which provide stormwater detention for
more than one development site, will be encouraged. Such basins shall
meet the design criteria contained in this section. Runoff from the
development sites involved shall be conveyed to the basin in a manner
so as to void adverse impacts, such as flooding or erosion, to channels
and properties located between the development site and the shared
storage basins.
(c)
As a general rule, detention basins will be designed as dry
basins, although wet basins will be considered in specific situations
where they can be shown to represent a significant amenity to the
development and/or the Township. Basins should be designed to induce
water depths as shallow as possible.
(d)
Except in approved wet basins, stormwater detention basins will
be designed to drain completely. A low-flow channel shall be installed
to facilitate the conveyance of storm sewer flows to the basin outlet
during frequent storm events. All interior portions of the basin will
slope toward the outlet or low-flow channel at a minimum slope of
1%. All impoundment areas shall be adequately underdrained to prevent
long-term ponding of water.
(e)
Detention basin outfall pipes shall have a minimum of two anti-seepage
collars installed along the profile of the pipe. Anti-seepage collars
shall be constructed of reinforced concrete.
(f)
All detention basins designed with an earthen dam shall provide
a minimum of one foot of freeboard between the peak emergency spillway
design flow elevation and the top of the embankment.
(g)
All embankments shall be designed, signed and sealed by a licensed
professional engineer according to sound engineering practice for
such structures and must meet the approval of the Township Engineer.
Basins with a design water depth in excess of 10 feet may require
a supporting report from a licensed professional engineer. In general,
impoundment areas shall be designed to be contained with areas excavated
within existing ground, rather than fill, whenever possible, Impoundment
areas designed within fill shall require a supporting report from
a geotechnical engineer addressing potential infiltration concerns
and recommended solutions.
(h)
The outside slopes of the embankment shall not exceed two horizontal
to one vertical. The interior slopes of the structure within the pool
area shall not exceed a slope of three horizontal to one vertical.
Design of basins with flatter, slopes for aesthetics and as a maintenance
consideration are encouraged. The crest of the embankment shall have
a minimum width of not less than 10 feet.
(i)
The embankment shall be level along the crest and along the
longitudinal center line. In the event that the embankment would be
overtopped by stormwater runoff, the flow over the crest and down
the downstream slope would be sheet flow rather than being concentrated
and eroding away the embankment. No trees shall be planted on the
embankment. The protective fence shall not be placed across the primary
or emergency spillways.
(j)
Except where special erosion protection measures are provided,
all disturbed areas will be graded evenly, topped with four inches
of topsoil, fertilized, seeded and mulched by methods consistent with
PennDOT Publication 408.
(k)
All outfalls to and from the basin shall be provided with endwalls
and erosion control measures.
(l)
Outlet control structures shall be constructed of reinforced
concrete (cast-in-place or precast) and shall be recessed into the
embankment wherever practical. Trash racks for low-flow control openings
should be designed to provide four to 10 times the area of the low-flow
opening and facilitate debris removal and maintenance.
(m)
An access easement with a minimum width of 20 feet to all stormwater
detention basins shall be provided to the Township. This access shall
be improved with a cartway consisting of four inches of crushed and
compacted aggregate having a minimum width of 10 feet and a maximum
grade of 15%. The access casement shall include a statement on the
recorded plan from the owner/operator of the basin granting access
to the Township.
(n)
Detention basins that are designed as sedimentation basins during
construction operations shall be desilted and regraded to original
design dimensions and have all temporary sedimentation-control devices
removed prior to their conversion to detention basins. Low-flow channels
and underdrains should be installed with the conversion of the basin.
(o)
In subdivisions or projects that are constructed in phases with
individual detention basins employed as sedimentation basins, said
basins shall be converted to their ultimate use as stormwater management
basins as soon as their tributary areas are stabilized per BCCD standards.
This conversion may be requested by the Township, with supportive
corroboration from the Beaver County Conservation District, and shall
be implemented as outlined in the approved erosion and sedimentation
control plan.
(p)
An as-built drawing shall be required for each stormwater detention
basin constructed. The drawing shall represent certification of the
volume of the basin and the depth-versus-storage relationship, as
well as the elevational relationships and dimensions of flow controls,
including emergency spillways, as appropriate. These relationships
shall be shown on the drawing in table form or in report form. In
the event that these relationships vary from the computations provided
in the approved plan, revised storm routings may be required at the
discretion of the Township. The as-built drawing shall be stamped
by a licensed professional engineer or surveyor and submitted to the
Township within 60 days of the completion of the basin. No basin will
be approved until this as-built drawing has been approved by the Township.
(5) Design criteria for collection/conveyance facilities.
(a)
As a general rule, no stormwater may be discharged to unprotected
areas such as hillsides or fills, without special erosion and/or energy-dissipation
controls being installed. Stormwater shall either be conveyed to the
nearest established stream channel as approved by the Township or
provided with an approved energy-dissipation device. Conveyance shall
be by pipe or erosion-protected ditch.
(b)
All sites shall be graded to provide drainage away from and
around structures to prevent potential flooding damage.
(c)
Collection/conveyance facilities should not be installed parallel
to or close to the top or bottom of major embankments to avoid the
possibility of embankment failure, with the exception of those facilities
specifically designed to prohibit stormwater runoff from eroding slopes
or preventing runoff from damaging downstream properties.
(d)
Stormwater shall be collected and conveyed from upslope areas
in a manner designed to prevent damage to downslope property(ies)
consistent with appropriate engineering standards. This system shall
be identified by permanent easements with the party responsible for
maintenance identified.
(6) Disposal of stormwater from roof, foundation and driveway drains.
(a)
Individual lots that are required to provide for on-lot stormwater
management basins per the stormwater management plan shall be identified
on the recorded plan(s) for the subdivision.
(b)
No roof, driveway or foundation drains shall be discharged onto
the right-of-way of any street or the pavement of any street. They
may be connected to the street stormwater collection system of pipes
or inlets. All residential dwellings not connected to a private or
public stormwater collection and management system shall install a
stormwater containment and disposal system at the direction of the
Township. Other acceptable methods of disposal include rain barrels,
underground tanks, infiltration devices (i.e., rain gardens), storm
sewers, large-diameter pipe-chamber systems and grassed or other ground
surfaces, provided adequate consideration is given to erosion protection,
or any other method approved by the Township.
(c)
At no time will any roof, driveway or foundation drains be allowed
to be connected to the sanitary sewer line.
(d)
The use of splash blocks is permitted. The location of the splash-block
discharge must be a minimum of five feet from foundations and five
feet from the property line. Exceptions to this method may be permitted
in the instance of townhouses or similar structures where common property
lines exist. No stormwater runoff may be directed in such a manner
as to disturb or damage neighboring properties.
(e)
Houses located on the low side of the road can use a solid pipe
or corrugated pipe (minimum of four inches' diameter) to the
rear of the lot to a point of discharge onto a rock apron (size and
dimensions to be specified) not less than 10 feet from the adjacent
neighboring property line, provided said discharge has been accounted
for within the approved stormwater management plan and the discharge
does not impact downstream property owners.
(f)
Lots shall be graded in such a manner as to divert stormwater
runoff away from adjacent property and structures consistent with
appropriate engineering standards.
All sanitary sewage facilities and all public water facilities
shall be constructed in accordance with the design standards and requirements
of all public boards or bodies having jurisdiction thereof.
All guiderails shall be constructed in accordance with the construction
standard in PennDOT Publication No. 72-M, Standards for Roadway Construction,
Drawing No. RC-53M, Type 2 Weak Post Guide Rail.
All installations, locations, and materials shall comply with
Township and PennDOT standards.

be installed prior to the Township issuing any building permits.
(2) Bonds shall not be released for the streets until all signage installations
receive final approval from the Township Engineer.
(3) When all signs have been installed, the developer must request the
Township to review the installations. The Township will give written
acceptance/denial. (A copy must go to the Township.)
(4) All developers must purchase and install all signs on their own.
The Township will not order, pay for, receive, store or install any
signs, posts, etc., for the developer.
When individual yard lighting is required in lieu of streetlights,
the perpetual energizing and maintenance of such shall be that of
the property owners. When streetlighting is made a requirement of
plan approval, the installation and initial startup shall be the responsibility
of the developer, and the perpetual energizing and maintenance once
the plan is fully accepted shall be that of the Township.
Stop bars, symbols, transverse markings, crosswalks, and longitudinal
