Stormwater Management Plan.
1.
Introduction. This Municipal Stormwater Management Plan (MSWMP) documents the strategy for Aberdeen Township to address existing and prevent future stormwater-related impacts. The creation of this plan is a required element as described in N.J.A.C. 7:14A-25 Municipal Stormwater Regulations. This plan contains all of the required elements described in N.J.A.C. 7:8 Stormwater Management Rules. The plan addresses groundwater recharge, stormwater quantity, and stormwater quality impacts by incorporating stormwater design and performance standards for new major development, defined as projects that disturb one or more acres of land or contain one quarter (1/4) acre of land or more of new impervious coverage. These standards are intended to minimize the adverse impact of stormwater runoff on surface water quality and water quantity and the loss of groundwater recharge that provides baseflow in receiving water bodies. The plan describes long-term operation and maintenance measures for existing and future stormwater facilities.
The plan addresses the review and update of existing ordinances, the Township Master Plan, and other planning documents, to allow for project designs that include low impact development techniques. The final component of this plan is a mitigation strategy for when a variance or exemption of the design and performance standards is sought. As part of the mitigation section of the stormwater plan, specific stormwater management measures have been identified, and may be further modified in the future, to lessen the impact of existing and new developments.
2.
Goals. The goals of this MSWMP are to:
Reduce flood damage, including damage to fife and property;
Minimize, to the extent practical, any increase in stormwater runoff from any new development;
Reduce soil erosion from any development or construction project;
Assure the adequacy of existing and proposed culverts and bridges, and other in-stream structures to handle existing and projected future flows;
Maintain groundwater recharge;
Provide, to the greatest extent feasible, a decrease in nonpoint pollution;
Maintain the integrity of steam channels for their biological functions, as well as for drainage;
Minimize pollutants in stormwater runoff from new and existing development;
Restore, enhance, and maintain the chemical, physical, and biological integrity of the waters of the State;
Protect the public health;
Safeguard fish and aquatic life and scenic and ecological values;
Enhance recreational and other uses of water;
Protect the public safety through the proper design and operation of stormwater detention/retention systems.
Encourage municipal action to guide the appropriate use or development of lands in the Municipality in a manner which will promote the public health, safety, morals, and general welfare.
Secure safety from fire, flood, panic and other natural and man-made disasters;
Promote the conservation of historic sites and districts, open space, energy resources and valuable natural resources in the Municipality;
Prevent urban sprawl and degradation of the environment through improper use of land; and
Promote utilization of renewable energy sources.
To achieve these goals, this plan outlines specific stormwater design and performance standards for new development and, where possible, through the development application review process, to mitigate impacts from existing development. Preventative and corrective maintenance strategies are included in the plan to ensure long-term effectiveness of stormwater management facilities. The plan also outlines safety standards for stormwater infrastructure to be implemented to protect public safety.

Stormwater Discussion. Land development can dramatically alter the hydrologic cycle (See Figure 1) of a site and, ultimately, an entire watershed. Prior to development, native vegetation can either directly intercept precipitation or draw that portion that has infiltrated into the ground and return it to the atmosphere through evapotranspiration. Development can remove this beneficial vegetation and replace it with lawn or impervious cover, reducing the site's evapotranspiration and infiltration rates. Clearing and grading a site can remove depressions that store rainfall. Construction activities may also compact the soil and diminish its infiltration ability, resulting in increased volumes and rates of stormwater runoff from the site. Impervious areas that are connected to each other through gutters, channels, and storm sewers can transport runoff more quickly than natural areas. This shortening of the transport or travel time quickens the rainfall-runoff response of the drainage area, causing flow in downstream waterways to peak faster and higher than natural conditions. These increases can create new, and aggravate existing, downstream flooding and erosion problems and increase the quantity of sediment in the channel. Filtration of runoff and removal of pollutants by surface and channel vegetation is eliminated by storm sewers that discharge runoff directly into a stream. Increases in impervious area can also decrease opportunities for infiltration to streams that depend on base flows in summer months and also decrease the potential for ground water recharge. Reduced base flows and increased peak flows produce greater fluctuations between normal and storm flow rates, which can increase channel erosion. Reduced base flow can also negatively impact the hydrology of adjacent wetlands and the health of biological communities that depend on base flows. Finally, erosion and sedimentation can destroy habitat and thus adversely impact some species that cannot readily adapt.
In addition to increases in runoff peaks and volumes and loss of ground water recharge, land development often results in the accumulation of pollutants on the land surface that runoff can mobilize and transport to streams. New impervious surfaces and cleared areas created by development can accumulate a variety of pollutants from the atmosphere, fertilizers, animal wastes, and leakage and wear from vehicles. Pollutants can include metals, suspended solids, hydrocarbons, pathogens, and nutrients.
In addition to increased pollutant loading, land development can adversely affect water quality in more subtle ways. For example, stormwater falling on impervious surfaces or stored in detention or retention basins can become heated and raise the temperature of the downstream waterway, adversely affecting cold water fish species such as trout. Development can remove trees along stream banks that normally provide shading, stabilization, and leaf litter that falls into streams and becomes food for the aquatic community.

Aberdeen Township Background.
4.1.
General.
Aberdeen Township, first established in 1677 and incorporated in 1857, encompasses a 5.4 square mile area in the northeast corner of Monmouth County, New Jersey. See Figure 2 for existing land uses. The population of the Township has remained relatively stable with minor fluctuations from 17,235 in 1980, to 17,038 in 1990, to 17,454 in 2000. See Figure 3 for existing zoning districts. However, in recent years, the Township has been under significant development pressure where several large development projects have either been approved and constructed or have received preliminary and final approval from the Township Planning Board and have intent to be under construction by early 2007. These developments are estimated to increase the population by approximately 1,600 individuals.
Changes in the landscape will most likely increase stormwater runoff volumes and pollutant loads to the waterways of the municipality. Figure 4 illustrates the waterways in the Township. Figure 5 depicts the Township boundary on the USGS quadrangle maps. Figure 6 shows vacant lands, a portion of which may be available for future development.
4.2.
Waterways.
The Township of Aberdeen is traversed by multiple waterways, generally flowing from the south/southwest to north/northeast to Raritan Bay.
Whale Creek forms a portion of the Township boundary with Old Bridge. Long Neck Creek and Treasure Lake discharge both flow into Whale Creek. Whale Creek is tidal up to approximately Route 35
Matawan Creek and Birch Swamp Brook both flow into Lake Lefferts (located in both Aberdeen and Matawan Borough). Gravelly Brook and its tributaries flow into Lake Matawan located in Matawan Borough. Both lakes discharge into Matawan Creek, which is tidal below the dams, and who flows into Raritan Bay. Mohingson Brook and its tributaries flow through the Strathmore section of the Municipality and into Matawan Creek. A portion of the Mohingson is also tidal to approximately the New Jersey Transit Railroad culvert.
Luppatong Creek flows northerly then easterly through a portion of the Strathmore section of the Township then crosses over into Hazlet Township and ultimately to Raritan Bay.
A substantial amount of the flows in the various brooks and creeks originate in communities beyond the borders of Aberdeen Township.
Raritan Bay is subject to restricted shellfish activities and is deemed as being moderately impaired.
The New Jersey Department of Environmental Protection (NJDEP) has established an Ambient Biomonitoring Network (AMNET) to document the health of the State's waterways. There are over 800 AMNET sites throughout the State of New Jersey. These sites are sampled for benthic macroinvertebrates by NJDEP on a five-year cycle. Streams are classified as non-impaired, moderately impaired, or severely impaired based on the AMNET data. The data is used to generate a New Jersey Impairment Score (NJIS), which is based on a number of biometrics related to benthic macroinvertebrate community dynamics. The one major water body that borders the Township to the northeast, the Raritan Bay, is moderately impaired. Accordingly, the various lakes, brooks, and creeks located within the Township, although are not individually listed in the AMNET data, as they are all tributary to the Raritan Bay, by definition, the tidal portions thereof must be considered as moderately impaired.
In addition to the AMNET data, the NJDEP and other regulatory agencies collect water quality chemical data on the streams in the State. This data shows that total Mercury, Bioxine, Pathogen and PCB concentrations of the Raritan Bay frequently exceed the State's criteria. This means that the bay is an impaired waterway and the NJDEP is required to develop a Total Maximum Daily Load (TMDL) of these pollutants for the bay (see appendix).
Further, per the Proposed 2004 Integrated List, Gravelly Brook is classified as severely impaired. Mohingson (or Wilkson's Brook), Whale Creek and Lake Lefferts are also impaired.
A TDML is the amount of a pollutant that can be accepted by a waterbody without causing an exceedance of water quality standards or interfering with the ability to use a waterbody for one or more of its designated uses. The allowable load is allocated along with a margin of safety to the various sources of the pollutant, such as stormwater and wastewater discharges, which require an NJPDES permit to discharge, and to nonpoint sources, which includes stormwater runoff from agricultural areas and residential areas. Provisions may also be made for future sources in the form of reserve capacity. An implementation plan is developed to identify how the various sources will be reduced to the designated allocations. Implementation strategies may include new or improved stormwater treatment facilities or plants, adoption of ordinances, reforestation of stream corridors, retrofitting stormwater systems, and other Best Management Practices (BMPs).
The New Jersey Integrated Water Quality Monitoring and Assessment Report (305(b)and 303(d)) (Integrated List) is required by the Federal Clean Water Act to be prepared biennially (every 5 years) and is a valuable source of water quality information. This combined report presents the extent to which New Jersey waters are attaining water quality standards, and identifies waters that are impaired. The Integrated List (proposed 2004) constitutes the list of waters impaired or threatened by pollutants, for which one or more TMDLs are needed. As previously indicated Raritan Bay and its various (tidal) tributaries, Mohingson Brook, Whale Creek and Lake Lefferts are moderately impaired, and Gravelly Brook is listed as severely impaired.
4.3.
Existing Stormwater Infrastructure.
Due to the age and the location of the Township, a substantial portion of the community, as well as its existing stormwater infrastructure, was built with minimal regard for stormwater control or management. Few detention or recharge facilities were constructed serving single family or commercial properties. Some facilities were constructed to serve multi-family projects and are owned and maintained by various homeowner associations. However, said facilities would not meet today's standards.
The Township previously located the majority of its stormwater outlet structures, numbering approximately 300 headwalls or pipe terminuses, in the early 1990's. In addition, the Municipality mapped a significant portion of the stormwater facilities in 1995+/-. However, said mapping was not in GIS or Arcview format.
Accordingly, in conformance with its Tier A Municipal Stormwater Permit requirements and its Stormwater Pollution Prevention Plan, the Township will remap all of its outfall facilities by 2009.
The Township's stormwater infrastructure has been well maintained. Should any difficulties arise, the Township endeavors to resolve them immediately. The Township has instituted a complaint hotline and response protocol that requires an investigation and response within 24 hours. For example, the Township's Public Works received complaints from a resident who reported a driveway cavein on her property. As a result, preliminary excavation and television investigations determined the bottom of the pipe rotted out. The soils within Aberdeen Township are very acidic clays creating a detrimental environment for pipes that have not been treated properly. Once the pipe started to corrode and create a rough surface on the inside of the pipe, debris began catching and collecting within the pipe. This significant amount of debris in the pipe created clogs reducing the effectiveness of the pipe leading to flooding around the troubled site.
After the pipe was televised and thoroughly cleaned out, it was slip-lined using a cured in place (CIP) liner. The liner created a smooth surface within the pipe which prevents any debris from accumulating and eliminated the eroded bottom while providing structural strength against potential future collapse. The residents confirmed that the pipe functioned well without flooding, thus demonstrating this project to be a success.
4.4.
Localized Flooding.
Although Aberdeen Township has many waterways, the Township has only limited flooding areas that are of concern to the Township itself. The flooding is caused by one or two categories-runoff or tidal.
4.4.1.
Tidal.
This type of flooding is normally caused by some type of storm event, such as a hurricane or northeaster coincident with high tide(s). There are several locations within the Township affected by these events.
Amboy Avenue proximate to the Matawan Creek Bridge into Keyport. This problem cannot be corrected due to the existing coastal wetlands and two commercial businesses on either side of the road that would be adversely impacted by raising the road and the fact that Keyport would have to undertake a similar project.
Prospect Avenue at Route 35 Northbound. The intersection would have to be raised, impacting two commercial access drives. The project is of low priority as an alternate route is easily accessed and the flooding frequency is low.
Lakeshore Drive between Ravine Drive and Ocean Boulevard. This area floods at extreme high tides and during storm events. Reconstruction would be exceedingly difficult and expensive due to poor subsoils, coastal wetlands on either side of the road, and NJDEP permitting requirements. However, this project has a higher priority due to the higher frequency of occurrence but reconstruction could not address hurricane events.
Beach Drive at the end of Shore Concourse during hurricane events. Flooding is periodic but controlled by a municipally operated tide gate.
Aberdeen Road (Matawan Borough). Extreme high tides and storm events cause road closures. Due to its location in an adjoining community, this problem area cannot be addressed by the Township.
4.4.2.
Runoff.
This type of flooding occurs as a result of a rainfall event whereby the capacity of existing stormwater infrastructure facilities is exceeded, i.e. a stream overflows its banks; a culvert backs up; or an inlet is clogged with debris or accumulated materials.
Route 35 at Whale Creek and at Long Neck Creek. The primary cause of flooding at these locations is runoff down the stream bed exceeding the culverts' capacity. These floodings have occurred regardless of high tide events. This problem is being addressed by NJDOT, who has a project under final design with anticipated construction in 2007 whereby the culverts will both be increased in size to permit flow passage and the roadway elevation will be raised by approximately three (3) feet.
Woodman Place off Warren Drive south of Lloyd Road experiences roadway flooding due to deficient pipe size to carry contributory flows. The Municipality has this project scheduled as a capital drainage project anticipated in approximately 2008.
Nutmeg/Normandy proximate to the NJ Transit Railway Line. This area floods due to a blocked culvert. Currently, NJ Transit is applying for permits to reconstruct its mainline culvert crossing and permit the secondary culvert to be cleared. Said project is scheduled for Fall 2006.
Ravine Drive (Matawan Borough). During severe rainfall events, Lake Lefferts overflows its spillway causing flooding of Ravine Drive causing road closings. Several plans have been formulated to address spillway reconstruction by the Borough but they lack funding for implementation. The Township's concern is interrupted access to other portions of its community for emergency response.
4.5.
Groundwater Recharge.
Groundwater recharge is a desirable element of an overall stormwater management plan in that recharge of the groundwater maintains subsurface flows, recharges potable water aquifers, and supports surface stream flows during base summer months.
The Township of Aberdeen's groundwater recharge areas are indicated on Figure 7. However, a substantial portion of said recharge areas have already been covered with developments, both residential and commercial, thus adversely impacting groundwater recharge rates.
The Municipality has every intent to pursue, through the development application review process and, when appropriate and practical, through mitigation projects, increasing groundwater recharge.
4.6.
Wellhead Protection.
Wellhead protection is required to protect drinking water supply wells from contamination; the wellhead protection areas are illustrated in Figure 8.
Wellhead protection is the primary responsibility of the potable water well owner starting with construction in accordance with NJDEP regulations, control (ownership) of lands immediately surrounding the well itself and controlling the pollutant sources, which can be done by, but not limited to, the following: minimizing hazardous substance use, pollution source removal, education, and training of operations personnel. However, the Municipality in which the wellhead protection area is located also has an obligation to provide for and assist in the development of wellhead protection.
Potable wells located in Aberdeen are those owned and operated by New Jersey American Water Company. The Township's prior potable water wells, located in the Cliffwood section, were abandoned and sealed in accordance with the requirements of the NJDEP. The Borough of Matawan has its well field located off of Middlesex Road south of Ravine Drive. The Borough of Keyport has its wellhead off of Route 35 proximate to Perry Street.
The Township will pursue wellhead protection through its development review process with a view towards eliminating the potential for pollution and/or contamination associated with stormwater facilities. Further, the Municipality will pursue education of the general public through brochures and newsletters and will perform annual training of its personnel in the observation of potential pollution sources and the elimination of same.
4.7.
Proactive Stormwater Efforts.
Even prior to the issuance by NJDEP of the NJPDES Tier A Municipal Stormwater General Permit, the Township of Aberdeen has actively pursued the improvement of stormwater quality throughout the Municipality. Some examples include:
Revised its Land Development Ordinances to provide for:
Buffers of 100' from top of bank of water courses for all residential uses. |
Tree save/restore provision to replace all trees removed during site clearance or pay for differential into a tree replacement fund. |
Redefine and clarify its "critical areas" including steep (>15%) slopes. |
Update its Natural Resources Inventory (2002)
Expand its "CR" Conservation/Recreation Zoning District
Update its Open Space and Recreation Plan 2004/Jan '05
Acquire 24 acres of land along Matawan Creek as open space in lieu of 48 housing units
Acquire 31 acres of land proximate to Long Neck Creek as open space in lieu of 34 housing units
Revise its development application review process to anticipate compliance with yet to be adopted stormwater regulations for recharge, TSS removal and flow reduction in both development and redevelopment projects
Change its roadway reconstruction projects standards to incorporate Campbell Foundry "J" Inlet, Eco-castings with bicycle grates for debris and trash control
Initiate labeling of inlet heads (approximately 100 units) contributory to Gravelly Brook with decals
Distribute educational handouts to its residents on Aberdeen Day relative to stormwater pollution prevention
Adopt required ordinances for: litter; pet waste control; wildlife feeding; proper waste disposal; illicit connection elimination; and stormwater control
Initiate annual Township personnel stormwater pollution prevention training
Maintain and upgrade existing street sweeping program to control litter and debris from entering storm sewers
Initiate education of residents through calendar, newsletter and website as to recycling, yard waste, stormwater pollution control, etc.
5.
Stormwater Design and Performance Standards.
On September 6, 2005, the Township passed Ordinance 18-2005, adopting the design and performance standards for stormwater management measures as presented in N.J.A.C. 7:8-5 to minimize the adverse impact of stormwater runoff on water quality and water quantity and loss of groundwater recharge in receiving water bodies. The design and performance standards include the language for maintenance of stormwater management measures consistent with the stormwater management rules at N.J.A.C. 7:8-5.8 Maintenance Requirements, and language for safety standards consistent with N.J.A.C. 7:8-6 Safety Standards for Stormwater Management Basins. The ordinance has been submitted to the County for review and approval within 24 months of the effective date of the NJPDES Stormwater permit.
During construction, Township inspectors will observe the construction of approved projects to ensure that the stormwater management measures are constructed and function as designed. If said measures are not taken to conform with these design standards, work will be stopped, a summons will be issued, fines will be implemented, and construction will be resumed and completed correctly. Code Enforcement will continue to inspect the stormwater facilities after construction to ensure that maintenance is performed and that facilities remain operational and structurally sound. Fees may be assessed against the developer's or responsible party's performance or maintenance guarantees.
6.
Plan Consistency.
The Township is not within a Regional Stormwater Management Planning Area and no TMDLs have been developed for waters within the Township; therefore this plan does not need to be consistent with any regional stormwater management plans (RSWMPs) nor any TMDLs. If any RSWMPs or TMDLs are developed in the future, this Municipal Stormwater Management Plan will be updated to be consistent therewith.
The Municipal Stormwater Management Plan is consistent with the Residential Site Improvement Standards (RSIS) at N.J.A.C. 5:21. The municipality will utilize the most current update of the RSIS in the stormwater management review of residential areas. This Municipal Stormwater Management Plan will be updated to be consistent with any future updates to the RSIS.
The Township's Stormwater Management Ordinance requires all major (greater than one acre disturbed lands or greater than one quarter acre of new impervious cover created) development plans to comply with the stormwater management regulations, including groundwater recharge. These regulations will also apply, to the greatest extent possible, to redevelopment projects as well. During construction, Township inspectors will observe on-site soil erosion and sediment control measures and report any inconsistencies to the Freehold Soil Conservation District.
7.
Nonstructural Stormwater Management Strategies.[2]
The Township is currently reviewing the master plan and existing ordinances and has provided a list of some of the sections in the Township land use and zoning ordinance that are to be modified to incorporate nonstructural stormwater management strategies as follows:
Section 4-4: Removal of grass, weeds, brush and other debris.
Sections 4-14.7a and 4-14.8: Removal of grass, bushes, branches, etc. Overhanging or obstructing sidewalks, streets, etc. and removal of same.
Section 4-15: Litter.
Section 7-2: Harboring, keeping and maintaining of certain animals: Licensing.
Section 12-10.14: Protection of watercourses.
Section 12-10.17: Surface restoration.
Sections 15-8.3 and 15-8.8: Improvements and design standards: curbs, gutters, catch basins and drainage system.
In addition to the above ordinances being revised to reference the requirements of the statutes, the following additional ordinances have been adopted for their compliance with the regulations:
Pet Waste (control and disposal)
Improper Disposal of Waste
Wildlife Ordinance (non-feeding)
Illicit Connection Ordinance (elimination of illicit connections or pollutant sources to stormwater facilities)
Once the ordinance texts are completed, they will be submitted to the County review agency for review and approval. A copy will be sent to the DEP at the time of submission.
The Township will evaluate all of the different zoning districts and standards within each district with regard to impervious cover to determine whether a reduction in impervious cover is appropriate. Figure 9 shows existing impervious surface percentage coverages. The Township will also evaluate a maximum percent of disturbance for each zone for areas identified as natural features. Also, if a developer is given a variance to exceed the maximum allowable percent of impervious cover, the developer must mitigate the impact of the additional impervious surfaces including water quality, flooding and groundwater recharge.

8.
Mitigation Plans.
This mitigation plan is provided for a proposed development (residential, commercial or industrial) that is granted a variance or exemption from the stormwater management design and performance standards. Such variance or exemption include projects reviewed by the Township under MLUL with waiver from Numerical Standards and projects performed by the Township under NJPDES Permit not in full compliance with Numerical Standards. Note that said variances or exemptions can only be a last resort after all other options, both non-structural and structural BMPs, have been explored and found to be unfeasible.
Presented is a hierarchy of options, which may be eliminated, updated or revised by the Township when deemed necessary. The plan will be periodically updated with a list of additional stormwater capital projects as outfall pipe investigations continue and areas of outlet erosion are discerned and the necessity for bank and channel stabilization of streams is determined.
The Township Engineer should be consulted to determine availability of mitigation projects. All mitigation projects are subject to approval of the Township Engineer and Governing Body.
Mitigation Project Criteria.
A mitigation project proposed by an applicant to mitigate for incomplete compliance with design and performance standard must include sensitive receptor analysis, including the impacts to stormwater quantity and stormwater quality. These impacts will be incorporated into the Mitigation Project. The Mitigation Project must be close to the original project, have legal authorization from the property owner/s and have no adverse impacts on other properties.
Submission requirements include impacts from noncompliance, narrative regarding waiver, design details, responsible party, maintenance, permits, and construction.
The mitigation project must be implemented within the same drainage area as the proposed development. If a suitable site cannot be located in the same drainage area as the proposed development, the mitigation project may provide mitigation that is not equivalent to the impacts for which the variance or exemption is sought, but that addresses the same issue. The project must provide additional groundwater recharge benefits, or protection from stormwater runoff quality and quantity from previously developed property, which does not currently meet the design and performance standards as outlined in the Municipal Stormwater Management Plan. The developer must ensure the long- term maintenance of the project, including the maintenance requirements under Chapters 8 and 9 of the NJDEP Stormwater BMP Manual.
Listed below are potential projects to compensate for the deficit from the performance standards resulting from the proposed project. More detailed information on the projects can be obtained from the Township Engineer. The Township maintains the right to update the projects listed below and is not held accountable for time frames or to construct any of the mitigation projects or potential mitigation projects.
Water Quality
Rehabilitation of Mohingson Creek, including redefining stream channel and floodplains between Nutmeg Road and NJ Transit R.O.W.
Rehabilitation of Mohingson Creek tributary behind Duda Lane, including redefining stream channel and floodplains.
Water Quantity
Rehabilitation of Gravelly Brook, including redefining stream channel and floodplains between Route 34 and Church Street.
Redesign and reconstruct existing stormwater culvert on Woodman Place proximate to Warren Drive.
Rehabilitation of unnamed tributary off of Aberdeen Road proximate to Union Avenue, including redefining stream channel and floodplains.
The listed mitigation projects are generalized environmental enhancement projects that provide groundwater recharge, control flooding or control nonpoint source pollution. The Township Engineer should be contacted for availability, description and any other necessary information pertaining to the projects listed above and those not listed.
Mitigation projects are subject to the approval of the Township Engineer and Governing Body. Each project is approved upon an individual basis considering the extent of the variance, waiver or exception granted. Mitigation projects may require cooperation with outside agencies such as the Freehold Soil Conservation Districts, Mosquito Commission, Army Corp of Engineers, etc.
The Municipality may allow a developer to provide funding or partial funding to the Municipality for an environmental enhancement project that has been identified in a Municipal Stormwater Management Plan, or towards the development of a Regional Stormwater Management Plan. Funding quantities are subject to the approval of the Township Engineer and Governing Body and will include costs or partial costs, including those associated with purchasing a property or easement for mitigation, and those associated with the long-term maintenance requirements of the mitigation measure.
