1.0 PROJECT DESCRIPTION

3 Ronson, LLC is proposing the construction of a 1,748 SF Fast Food Restaurant with an additional 1,159 SF

of Mixed-Use Retail Space within. The subject property is designated Block 88.01, Lot 43, commonly known as

1165 NJ State Route 27, located at the corner of Veronica Avenue and Lincoln Highway (NJ State Route 27).

The total project area is 217,811 SF (5.00 acres), the total area of new impervious surfaces is 5,146 SF (0.12

acres, and the total area of disturbance is 55,468 SF (1.27 acres). Project Figures can be found in Appendix A of

this Report.

This Stormwater Management Report has been prepared to analyze the potential stormwater runoff impacts

of the proposed project and discuss the measures proposed to conform to the stormwater management

requirements set forth by the Township of Franklin, Somerset Union Soil Conservation District, NJ Department

of Transportation and the New Jersey Department of Environmental Protection (NJDEP).

2.0 EXISTING CONDITIONS

The project site is currently developed with two (2) existing Mixed-Use Retail Buildings, of 17,626 SF and

13,228 SF respectively. Existing site access is provided via a full movement driveway along Veronica Avenue and a

Right Ingress / Right Egress driveway along NJ State Route 27. The project site largely consists of impervious

paved surfaces and parking area with vegetated grasses surrounding the perimeter of the site with a large above

ground basin at the south-west corner of the site.

2.1 EXISTING DRAINAGE AREAS

Under existing drainage conditions, the site is comprised of four (4) drainage areas which convey stormwater

runoff offsite to two (2) Points of interest along Veronica Avenue and NJ State Route 27 respectively. The

majority of the site runoff is directed to the above ground basin at the southwest corner of the site which is

currently insufficiently sized to handle the 100-year storm event. The site generally slopes from the Northeast

corner of the Site to the Southwest corner of the site with a change in elevation of approximately four feet. The

site is previously developed by two (2) one-story Mixed-Use Retail Buildings with associated asphalt pavement in

the parking areas and concrete walkways.

3.0 PROPOSED CONDITIONS

Under the proposed development plan, the project area small portion of the existing grass on-site along the

Veronica Avenue frontage will be cleared to accommodate the proposed 2,907 SF Fast Food and Retail Building

with associated walkways and parking facilities. Improvements will also include lighting, utilities, and landscaping.

All existing features within the limit of disturbance are proposed to be demolished.

3.1 PROPOSED DRAINAGE AREAS

Under proposed drainage conditions, the site is comprised of four (4) drainage areas which convey

stormwater runoff offsite to two (2) points of interest along Veronica Avenue and NJ State Route 27 respectively.

The existing above ground basin is to be expanded to provide sufficient storage for the 100-year storm event and

a 80% Water Quality Unit is proposed to treat the additional runoff created by the proposed development. Site

slopes will remain substantially similar in the proposed condition with the four-foot elevation change remaining.

4.0 ANALYSIS METHODOLOGY & DESIGN PARAMETERS

4.1 HYDROLOGIC & HYDRAULIC ANALYSES

The existing and proposed drainage areas have been analyzed utilizing a modified version of the NRCS SCS

TR-20 method. The analysis program “HydroCAD” Version 9.10 by HydroCAD Software Solutions LLC was

used to calculate and plot the runoff hydrographs. The program incorporates the time of concentration, CN

values, 24-hour rainfall events, and project drainage areas to calculate the runoff characteristics. Key variables

utilized include the SCS Unit Hydrograph, a minimum time of concentration of 10 minutes, separate runoff

calculations for impervious and pervious areas, and dynamic storage and conveyance routing to account for any

variable tailwater conditions.

4.2 NEW JERSEY STORMWATER DESIGN PARAMETERS

The project is proposing to disturb 1.27 acres of land. Per the applicable stormwater standards, the project is

classified as a Major Development and is subject to stormwater quantity and groundwater recharge regulations.

Additionally, the project will add 0.12 acres of new impervious areas and will thus be subject to stormwater

quality regulations.

TABLE 4: PROJECT STORMWATER DESIGN INTENT SUMMARY TABLE

Design Parameters Design Intent For Compliance

Stormwater Quantity

Demonstrate through hydrologic and hydraulic analysis that for stormwater leaving

the site, post-construction runoff hydrographs for the 2, 10, and 100-year storm

events do not exceed, at any point in time, the pre-construction runoff

hydrographs for the same storm events.

Design stormwater management measures so that the post-construction peak

runoff rates for the 2, 10, and 100-year storm events are 50%, 75%, and 80%,

respectively, of the pre-construction peak runoff rates. The percentages apply only

to the post- construction stormwater runoff that is attributable to the portion of

the site on which the proposed development or project is to be constructed.

Groundwater Recharge

Demonstrate through hydrologic and hydraulic analysis that the site and its

stormwater management measure maintain 100% of the average annual pre-

construction groundwater recharge volume for the site

Demonstrate through hydrologic and hydraulic analysis that the increase of

stormwater runoff volume from pre-construction to post-construction for the

two-year storm is infiltrated.

Stormwater Quality

Stormwater management measures shall be designed to reduce the post-

construction load of total suspended solids (TSS) in stormwater runoff generated

from the water quality storm by 80% of the anticipated load from the developed

site, expressed as an annual average

4.3 SUBSURFACE STORMWATER INVESTIGATION

A subsurface stormwater investigation was conducted by ANS Consultants on August 23th, 2019. A total of

2 tests were performed in compliance with the soil testing standards outlined within Appendix E of the NJDEP

Best Management Practices (BMP) Manual. All proposed stormwater facilities meet or exceed the minimum

separation depth from seasonal high groundwater. The full investigation report and testing results can be found in

Appendix D of this Report.

Based on the testing results a design infiltration rate of 4.0 inches per hour was utilized in the design of

aboveground basin.

Per Table 7 and Point of Interest 2, the proposed project will meet stormwater quantity requirements via

demonstrating that at no point in time does the post-development hydrograph exceed the pre-development

hydrograph; as impervious surfaces decrease, the post-construction hydrograph will at no point exceed the pre-

development hydrograph.

5.2 GROUNDWATER RECHARGE

Utilizing the New Jersey Groundwater Recharge Spreadsheet (NJGRS) a comparison between existing and

proposed landcover within the project area was generated and an annual groundwater deficit of 5,520 CF is

anticipated. To compensate for this loss in passive groundwater recharge, the proposed reconstructed

aboveground infiltration basin will collect runoff and infiltrate it into the local groundwater table. Incorporating

these infiltration BMPs into the NJGRS yields a surplus recharge volume of 12,745 CF annually. Refer to the

NJGRS inputs and summary spreadsheets within Appendix C of this Report.

Under post-construction conditions, 864 CF of additional runoff is generated on site. The incorporation of

the proposed reconstructed aboveground infiltration basin reduces the overall site runoff below pre-construction

conditions. via infiltration as outlined in the table below.

5.4 STORMWATER CONVEYANCE SYSTEMS

The stormwater conveyance system has been sized for the 100-year storm and is able to safely convey runoff

to stormwater management facilities without overflowing. A summary of the pipe network and pipe profiles can

be found in Appendix C of the Report.

5.5 SOIL EROSION & SEDIMENT CONTROL

A Soil Erosion & Sediment Control Plan has been prepared in accordance with the latest edition of the

Standards for Soil Erosion and Sediment Control in New Jersey. Proposed temporary measures during

construction include silt fencing, stabilized construction entrances, inlet filters, and cover for soil stabilization.

Permanent post-construction measures include conduit outlet projection and native vegetation. No land

disturbance will occur until a permit has been obtained from the Somerset-Union Soil Conservation District.

5.6 STORMWATER OPERATIONS & MAINTENANCE

A Stormwater Operations & Maintenance Manual will be submitted for approval to the Township of Franklin

prior to the start construction. Any required easements or covenants associated with the stormwater

improvements will be recorded prior to the start of construction.

6.0 CONCLUSIONS

The proposed project complies with all applicable stormwater management regulations and standards. Runoff

quantity, recharge, and quality requirements are addressed by the implementation of one (1) water quality unit,

and an above-ground infiltration basin, As such, the project is not anticipated to have any adverse impacts or

neighboring properties, downstream watercourses, or conveyance systems within the watershed. The

reconstructed aboveground infiltration basin is now sufficiently sized to handle the 2, 10 and 100-Year Storm

events while treating any additional runoff created by the proposed development with the 80% Water Quality

Unit.

PrefaceSoil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment.

Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951).

Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations.

The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey.

Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are MadeSoil surveys are made to provide information about the soils and miscellaneous areas in a specific area. They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity.

Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA.

The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape.

Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil

scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research.

The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas.

Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape.

Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties.

While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

Your area of interest (AOI) includes more than one soil survey area. These survey areas may have been mapped at different scales, with a different land use in mind, at different times, or at different levels of detail. This may result in map unit symbols, soil properties, and interpretations that do not completely agree across soil survey area boundaries.

Map Unit Descriptions (Soil Map)The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not

mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities.

Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

the soil type and a shallow root zone for this Land Cover allowing consideration of lateral flow and other losses.

How to solve for different recharge volumes: By default the spreadsheet assigns the values of total deficit recharge volume "Vdef" and total proposed impervious area "Aimp" from the "Annual Recharge" sheet to "Vdef"

and "Aimp" on this page. This allows solution for a single BMP to handle the entire recharge requirement assuming the runoff from entire impervious area is available to the BMP.

To solve for a smaller BMP or a LID-IMP to recharge only part of the recharge requirement, set Vdef to your target value and Aimp to impervious area directly connected to your infiltration facility and then solve for ABMP or

dBMP. To go back to the default configuration clik the "Default Vdef & Aimp" button.
