ARTICLE I

GENERAL PROVISIONS

SECTION 101. STATEMENT OF FINDINGS

The Board of Supervisors of the Township of Dingman finds that:

A. Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed may increase flow volumes and velocities, contribute to erosion and sedimentation, overtax the carrying capacity of streams and storm sewers, increase the cost of public facilities to carry and control stormwater, undermine floodplain management and flood control efforts in downstream communities, reduce groundwater recharge, deteriorate the water quality of receiving waters, and threaten public health and safety.

B. A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated runoff is fundamental to the public health, safety, and welfare and the protection of the people of the Township of Dingman and all the people of the Commonwealth, their resources, and the environment.

C.  Areas of the Sawkill Watershed are sensitive to development due to the exceptional value water resources and the nature of the Watershed geology, requiring additional mitigating measures for earth disturbance and site development. Additional safeguards must also be provided for commercial and industrial developments to minimize the potential for hazardous substance spills including, but not limited to the implementation of spill preventions plans.

D.  The Milford Water Authority secures its drinking water from the Milford Springs which lie within the Sawkill Watershed. The Authority has identified soure water protection zones, entitled Zone 1, Zone 2, and Zone 3 in it’s Sourcewater Protection Plan for the Milford Springs, as approved by PADEP in 2006. The geology found within the Zone 1 and Zone 2 areas are sensitive to environmental impacts due to the potential for contamination of the Milford Water Authority Public Drinking Water supply.

E.   The above referenced Source Water Protection Plan identifies several methods for managing potential risks to the Milford Springs.  Among these is the need for municipal cooperation and for tributary municipal bodies, including Dingman Township and its Planning Commission, to identify any development aspect posing a potentially significant impact to te Milford Springs so that appropriate protective measures can be implemented.

SECTION 102. PURPOSE

The purpose of this Ordinance is to promote the public health, safety and welfare and protect surface and groundwater resources within the Sawkill Creek Watershed by minimizing the damages described in Section101 of this Ordinance. To accomplish this, the Ordinance establishes a comprehensive stormwater management program designed to:

B.     Minimize impervious surfaces

C.     Manage accelerated runoff and erosion and sedimentation problems at their source by regulating activities which cause such problems.

D.     Utilize and preserve existing natural drainage systems.

E.     Encourage recharge of groundwater where appropriate.

F.     Maintain the existing flows of streams and watercourses in the Township of Dingman and the Commonwealth.

G.     Preserve and restore the flood carrying capacity of steams.

H.     Provide for proper design, installation, and maintenance of all permanent stormwater management structures which are constructed in the Township of Dingman.

I.     Promote project designs and best management practices that minimize impacts to surface and ground water quality and quantity from development and pollution sources.

J.     Provide procedures and performance standards for stormwater planning and management.

STORMWATER MANAGEMENT REQUIREMENTS

SECTION 301. GENERAL REQUIREMENTS

A.     Any facilities that entail earth disturbance activity, as described in Article II, shall be conducted in such a way as to minimize accelerated erosion and sediment pollution. Measures to control erosion and sediment pollution and stormwater runoff shall at a minimum, meet the standards of the Pike County Conservation District and 25 PA Code Chapter 102 (Erosion Control) the Delaware River Basin Commission (DRBC) Special Protection Waters regulations, the National Pollutant Discharge Elimination System (NPDES) permit for stormwater discharges from construction activities, and PA Code Chapter 93 Water Quality Antidegradation Regulations. Where the above regulations and this ordinance conflict, the more restrictive of the two on the matter at issue shall control.

B.     Any facilities that are regulated by PA DEP Chapter 105 regulations (Dam Safety and Waterway management, as amended or replaced from time to time by PA DEP) shall be designed in accordance with Chapter 105 and will require a permit from PA DEP. Any other drainage conveyance facility that does not require a Chapter 105 permit must be able to convey, without damage to the drainage structure upland areas or roadway, runoff from the 25 year design storm with a minimum 1.0 foot of freeboard measured below the lowest point along the top of the roadway.  Structures intended to impound surface water or groundwater shall not negatively impact the recharge of groundwater to the source aquifer.

C.     Stormwater management facilities located within or affecting the floodplain of any watercourse shall be subject to the requirements of Chapter 106 regulations (Flood Plain management Act) and any Township ordinance which regulates construction and development within areas which are subject to flooding.

D.     Stormwater management facilities must be designed so that the post development runoff rates are controlled in accordance with the mean annual (2.33) (pre-development and post-development flows) and 10 year design storm with applied release rates. The facilities shall require safe passing of up to and including 100 year storm event through basin structures. Should the physical parameters of a detention basin be such that more than 1,000 acre feet of storage, or if the dam is more than 40 feet high, Chapter 105 regulations should require a design flow greater than the 100 year event.

E.     Any Stormwater Management Facilities regulated by this Ordinance that would be located on a State Highway Right-of-Way shall be subject to approval by PA DOT.

F.     It is the responsibility of the developer to provide a site specific drainage design that controls the rate, volume and quality of stormwater runoff from the project using the following design principles:

1.     Minimize disturbed areas

2.     Retain and utilize natural site conditions and topography

3.     Maintain natural hydrology

4.     Minimize impervious areas and disconnect impervious surfaces

5.     Provide opportunities for groundwater recharge (where applicable)

6.     Utilize non-structural BMPs before structural BMPs

7.    Fully evaluate non-discharge alternatives and Implement water quality controls for all stormwater discharges to surface or groundwater

8.    Protect stream channels from degradation (e.g. scour, streambank destabilization) and maintain riparian buffers.

9.     Prevent increased flooding or erosion due to the runoff rate or volume

10.   Ensure long-term operation and maintenance of BMPs

G.     Impervious Area for drainage design should be calculated using the following:

1.     The measurement of impervious areas shall include all of the impervious areas in the total proposed development even if development is to take place in stages.

2.     For development taking place in stages, the entire development plan must be used in determining conformance with this Ordinance.

3.     For projects that add impervious area to a parcel, the total impervious area on the parcel is subject to the requirements of this ordinance.

H.     It is the responsibility of the developer to assure that the maximum rate of storm water runoff is no greater after development than prior to development activities and that the quantity, velocity and direction of resulting storm water runoff is managed to protect health and property from possible injury

I.      Stormwater shall be conveyed to a natural outfall that has sufficient capacity to receive the design storm peak runoff from the watershed without deterioration of the facility and without adversely affecting property in the watershed. This natural outfall may be a river, creek, intermittent flow drainage ditch or other drainage facility identified by the site topography and field conditions. Discharge at the natural outfall shall also be velocity controlled to prevent erosion.

J.      Sites which present the potential for hazardous substances entering the stormwater water collection and conveyance system shall employ containment and treatment measures to prevent the transport of hazardous materials to the ground or surface water.

All sites where hazardous materials are stored for use or re-sale on a temporary or permanent basis shall prepare a Spill Prevention Plan as required by Sections 503 and 504 for review by the Township, and the Milford Water Authority. Innovative stormwater management systems maybe used when approved by the Township of Dingman. Various combinations of stormwater management systems should be developed to suit the particular, unique requirements of the development and topographic features of the development site. Engineering data shall be supplied to the Township in support of such measures.

Approval of a proposed stormwater management control facility using these innovative methods shall depend on the effectiveness of the facility in controlling the impacts of post-development runoff rates and volumes and the design and construction specifications. The following is a partial listing of control methods which can be used in stormwater management facilities where appropriate:

a. French Drains

b. Infiltration Trenches

c. Porous Pavement

d. Pre-case Concrete Lattice Blocks and Bricks

e. Terraces, Diversions and Runoff Spreaders

f. Seepage Pits or Dry Wells

g. Seepage Beds or Ditches

h. Seepage Areas

i. Detention Basins

j. Parking Lot Storage

General descriptions, including the operation and maintenance of these Stormwater Management Facilities are provided in Section 5 of the Sawkill Stormwater Management Plan.

K.     Should a given property contain  portions of multiple protection zones, it is the responsibitity of the developer to minimize impacts to the more critical zone to the extent possible when implementing stormwater management controls.

L.     Due to the sensitive nature of the surface and groundwater within the Sawkill watershed, pretreatment of stormwater shall be required for all infiltration practices and discharges. Pre-treatment practices shall comply with the PADEP Best Management Practices Manual and shall be for 100% of the two (2) year storm events.

M.   Access to facilities shall be provided for maintenance and operation. This access shall be a cleared and graded access that is, a minimum of fifteen (15) feet wide. Proximity of facilities to public Right-of-Ways shall be encouraged in order to minimize the length of easements or Right-of-Ways. Multiple accesses shall be encouraged for major facilities. Appropriate easements or Rights-of-Ways must be provided to allow access to the stormwater management facilities by Township personnel and equipment. Facilities shall be designed to provide necessary access for required maintenance.

N.      Due to the sensative nature of the surface waters and groundwater within the Sawkill Watershed, new water source withdrawals for private development, including  the construction of new private water supply wells, should be developed as to avoid impact to the Milford Springs.

O.   All control facility designs shall conform to the applicable standards and specifications of the following governmental and institutional agencies.

American Society of Testing and Materials (ASTM)

Asphalt Institute (AI)

Pike County Conservation District

Federal Highway Administration (FHWA)

National Crushed Stone Association (NCSA)

National Sand and Gravel Association (NSGA)

Pennsylvania Department of Environmental Protection (PADEP)

Pennsylvania Department of Transportation (PADOT)

P.      No Harm Option

The intent of this Section is to allow for flexibility of design when downstream storage volume is available to development projects located near lakes, streams, wetlands or other natural features. This option is only available once the developer can demonstrate compliance with the nondischarge alternatives and existing use provisions of 25 PA Code 93.4c(b)(1)(i)(A) and (B). "No Harm" proposals are not acceptable for Zone 2 of the SourceWater Protection Zone.  The final determination of this “no harm” option shall rest solely and exclusively with the Township.

Proposed “no harm” justifications shall be submitted by the developer as part of the Drainage Plan Submission re: Article IV.

Proposals to prove “no harm” based upon downstream peak flow versus capacity analysis shall be based on a 10 year storm event for flows and shall be governed by the following provisions:

1.     The peak flows to be used for downstream areas for various return period storms shall be the values from the PSRM Model for the Sawkill Creek Watershed.

2.    Any available capacity in the downstream conveyance systems as documented by a developer and approved by the Township may be used by the developer and approved by the Township may be used by the developer only in proportion in their development site acreage relative to the total upstream acreage from the identified capacity (i.e. if their site is 10% of the upstream acreage, they may use up to 10% of the documented downstream available capacity.)

3.     Developer-proposed runoff controls which would generate increased peak flow rates at documented storm drainage problem areas as determined by the Township shall, by definition, be precluded from using the “no harm” option, except in conjunction with proposed capacity improvements for the problem areas.

SECTION 302. STORMWATER MANAGEMENT SUBAREAS

A.     Mapping of Stormwater Management Subareas – In order to implement the provisions of the Sawkill Creek Stormwater Management Plan, the Township is divided in to subareas as delineated on Plate No. 3 in the Stormwater Plan.

B.     Identification of Critical Areas – Critical areas for peak flow rates have been defined using the Release Rate formula. These release rates dictate the extent to which post development runoff must be controlled. Within a given sub-watershed, the post development peak flow rate of storm runoff must be controlled to the stated percentage of the pre-development peak rate of storm runoff fin order to protect downstream watershed areas. All sub-watersheds not listed in the following table have a release rate of 100%.

Subwatershed

Release Rate Percentage

   
4 70
13 80
14 80
15 80
17 80
18 80
19 80
20 80
22 80

 

SECTION 303. METHODS OF CALCULATION OF RUNOFF FLOW PARAMETERS

A.     The methods of computation used to determine peak discharge volume of runoff or design hydrographs shall be one of the following four methods or any other method approved by the Township engineer in advance.

1. The USDA NRCS Soil Cover Complex Method as set forth in the latest edition of “Urban Hydrology for Small Watersheds”, Technical Release No. 55.

2. The USDA NRCS Soil cover Complex Method as set forth in the “TR-20 computer Program for Project Formulation Hydrology” Technical Release No. 20.

3. The Penn State Runoff Model (PSRM) as set forth in the Penn State Runoff Model User’s Manual, latest revision.

4. For drainage areas less than 20 acres without retention/detention systems or up to 200 acres for design of local pipe system, the Rational method may be used. Where any overland control facility is proposed, one of the above methods shall be used. The “Rational method” of Q=CIA, where Q is the peak discharge from the watershed in cubic feet per second (cfs), C is the co-efficient of runoff, I is the intensity of rainfall in inches per hour and A is the area of the watershed in acres.

B.     Rainfall frequency data to be used depends on the method of computation selected.

5. When the NRCS Soil cover Complex method is used, storm runoff shall be based on the following storm events and reflect the SCS Type II 24-hour rainfall distribution.

STORM EVENT

INCHES OF RAINFALL

   
2.33 year 2.94
5 year

3.76

10 year 4.43
25 year 5.25
50 year 5.89
100 year 6.50

When the Rational Method is used, the Region 4 or Region 5 Rainfall Intensity Duration Frequency charts shown in the PADOT Design Manual (Manual), Part 2, latest revision, as amended shall be used to determine the rainfall intensity, in inches per hour. The charts are shown on Figures 2.10 4.2(D) and 2.10 4.2(E) of the Manual should be used to determine if Region 4 or Region 5 curves are to be used.

C.      Runoff Curve Numbers (CN’s) to be used in the Soil Cover Complex methods shall be based upon the matrix presented in NRCS TR 55, Table 2.2.a.

D.      Time of Travel (Tt) estimates for overland flows shall be computed using the method as describe din NRCS TR 55, Chapter III.

E.      Runoff coefficients for use in the Rational Method shall be based upon the table presented in Appendix B.4 of this Ordinance.

F.      The Manning equation shall be used to calculate the capacity and velocity of flow in open channels without backwater producing structures and in closed drains not under pressure. Manning “n” values used in the calculations shall be consistent with the table presented in Appendix B.5 of this Ordinance. Where backwater impacts are potentially present, the US Army Corps of Engineers HEC 2 program as set forth in “HEC 2 Water Surface Profiles Users Manual” or equivalent shall be used.

G.     All runoff calculations shall include both a hydrologic and hydraulic analysis indicating: 1) rates and velocities of flow; 2) grades, dimensions, and capacities of water carrying structures and impoundment structures; and 3) sufficient design information to construct such stormwater management facilities. Runoff calculations shall include both pre-development and post development rates of peak discharges and volumes of storm runoff from the project development site. Runoff calculations for the site’s conditions during development shall be used to size temporary control measures.

A.     The Board of Supervisors may hear requests for waivers where it is alleged that the provisions of this Ordinance inflict unnecessary hardship upon the applicant. The waiver request shall be in writing using an application form promulgated by the Township of Dingman. A copy of the completed application form shall be provided to each of the following: Township, Township Engineer, Township Solicitor, Township Planning Commission, and the Milford Water Authority. The application shall state in full the grounds and facts of hardship on which the request is based, the provision or provisions of the Ordinance involved and the minimum waiver necessary.

B.     The Township of Dingman may grant a waiver of one or more provisions of this Ordinance provided that such waiver will not be contrary to the public interest and that all of the following findings are made in a given case:

1. That there are unique physical circumstances or conditions, including irregularity of lot size or shape, or exceptional topographical or other physical conditions peculiar to the particular property, and that the unnecessary hardship is due to such conditions, and not the circumstances or conditions generally created by the provisions of this Ordinance (The presence of Source Water Protection Zone 2 on a given property shall not be considered a valid basis for a waiver);

2. That because of such physical circumstances or conditions, there is no possibility that the property can be developed in strict conformity with the provisions of this Ordinance, including the direct discharge option documented in Section 301 (P), and that the authorization of a waiver is therefore necessary to enable the reasonable use of the property;

3. That such unnecessary hardship has not been created by the applicant; and

4. That the waiver, if authorized, will not represent the minimum waiver that will afford relief and will represent the least modification possible of the regulation in issue.

C.     In granting any waiver, the Township of Dingman may attach such reasonable conditions and safeguards as it may deem necessary to implement the purposes of this Ordinance. The Township of Dingman shall keep a record of all action on all requests for waivers.

SECTION 1102. REPEALER

Any ordinance of the Township of Dingman inconsistent with any provisions of this Ordinance is hereby repealed to the extent of the inconsistency.

SECTION 1103. COMPATIBILITY WITH OTHER PERMIT AND ORDINANCE REQUIREMENTS

Permits and approvals issued pursuant to this Ordinance do not relieve the applicant of the responsibility to secure required permits or approvals for activities regulated by any other applicable code, rule, act, or ordinance. If more stringent requirements concerning regulation of stormwater or erosion or sedimentation pollution control are contained in any other code, rule, act, or ordinance, the more stringent regulation shall apply.
