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 the stormwater management plan.

A list of any permits/approvals relative to stormwater management that will be required from other governmental agencies (e.g., an obstructions permit from PADEP) and anticipated dates of submission/receipt should be included with the plan submission. 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]
[2]
Editor's Note: See Ch. 112, Floodplain Management.
[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.
