## Storm Sewer Design The proposed storm sewers have been designed in accordance with relevant requirements. The storm sewer was designed using the Rational method, the NJ Intensity-Duration-Frequency table, and a time of concentration minimum of 10 minutes. The storm sewers were sized to convey a 25-year storm event. Storm sewer calculations are included in the Appendix. ## Compliance ## Water Quality In accordance with N.J.A.C. 7:8-5.5(b) 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 design storm by eighty percent TSS removal of the anticipated load, expressed as an annual average for the stormwater runoff from the net increase of motor vehicle surface. Currently, the site contains 0.26 acres of motor vehicle surface which does not receive water quality treatment. The proposed site will contain 0.79 acres of motor vehicle surface for a net increase of 0.53 acres. As the existing motor vehicle surface does not receive water quality treatment, the equivalent redevelopment area would only require 50% TSS removal. This credit can be used to offset the portions of the proposed driveways that will run off untreated. However, the entire proposed motor vehicle surface will be treated for 80% TSS removal and so the proposed stormwater management will exceed the required TSS removal for the site.

As demonstrated above, the proposed stormwater management will exceed the required TSS removal for the site. ## Water Quantity N.J.A.C. 7:8-5.6 outlines the requirements to demonstrate that the proposed development will not result in stormwater runoff quantity impacts. The proposed development has been designed to reduce peak rates of runoff in compliance with N.J.A.C. 7:8-5.6(b)3.: Design stormwater management measures so that the post-construction peak runoff rates for the current and projected two-, 10-, and 100-year storm events, as defined and determined pursuant to N.J.A.C. 7:8-5.7(c) and (d), respectively, are 50, 75, and 80 percent, respectively, of the preconstruction 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. Water quantity attenuation will be provided by infiltration through infiltration basins. The site runoff will be first treated through either bioretention basins or porous pavement. The runoff will then be routed to the infiltration basins.

===== PAGE 13 ===== # Stormwater Management Report South Hope Chapel Rd. Subdivision Project #23184 ## Groundwater Recharge In accordance with N.J.A.C. 7:8-5.4(b), groundwater recharge can be met by infiltrating the increase in runoff from the 2-year storm event. The proposed GI infiltration basins will fully infiltrate the increased runoff from a 2-year storm event. Therefore, the requirement is met. ## Green Infrastructure In accordance with N.J.A.C. 7:8-5.3 groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards must be met using green infrastructure (GI). Green infrastructure is defined as a stormwater management measure that manages stormwater close to its source by either treating stormwater runoff through infiltration into subsoil, treating stormwater runoff through filtration by vegetation or soil; or storing stormwater runoff for reuse. The proposed stormwater management design complies with the NJDEP criteria for Small Scale Green Infrastructure as demonstrated below

## Groundwater Mounding Analysis In accordance with N.J.A.C. 7:8-5.2(h) whenever the stormwater management design includes one or more BMPs that will infiltrate stormwater into subsoil, the design engineer shall assess the hydraulic impact on the groundwater table and design the site, to avoid adverse hydraulic impacts. A groundwater mounding analysis has been prepared for the proposed green infrastructures (GI) using the USGS Hantush spreadsheet in accordance with NJDEP BMP Manual Chapter 13. The proposed GI's have been modeled using infiltration for all storm events. Therefore, the groundwater mounding analysis has been performed for the infiltration volume generated by the future 100-year storm event as calculated by HydroCAD.

## Soil Erosion and Sediment Control Soil erosion and sediment control measures have been designed in accordance with the Standards for Soil Erosion and Sediment Control in New Jersey and are shown on the plan. These include stormwater management, silt fence, inlet protection, stabilized construction access, and temporary and permanent stabilization ## Point Discharge Stability Point Discharge stability can be met by either maintaining existing peak rates of runoff for a “failure analysis” which ignores infiltration and storage below the lowest basin outlet or by demonstrating stable conditions under the proposed design. Ocean County Soil Conservation district has adopted current precipitation adjustment factors at N.J.A.C. 7:8-5.7(c), the values of which are reflected in the tables below. ===== PAGE 17 ===== # Stormwater Management Report South Hope Chapel Rd.

County specific data has been utilized to determine the precipitation depths. The current and future precipitation depths have been calculated and utilized. ===== PAGE 18 ===== # Stormwater Management Report South Hope Chapel Rd. Subdivision Project #23184 (2) In calculating stormwater runoff using the NRCS methodology, the appropriate 24-hour rainfall depths as developed for the parcel by the National Oceanic and Atmospheric Administration shall be utilized. The Ocean County 24-hour rainfall depths provided in the NJDEP BMP Manual Chapter 5 have been utilized which have been developed from NOAA Atlas 14. iii. Runoff shall meet the requirements at N.J.A.C. 7:8-5.6 and (a) 6iii(1) and (2) below: Runoff will meet the stormwater runoff quantity standards of N.J.A.C. 7:8-5.6 by meeting peak rate reductions per of N.J.A.C. 7:8-5.6(b)3. for each point of analysis as outlined below: Design stormwater management measures so that the post-construction peak runoff rates for the current and projected two-, 10-, and 100-year storm events, as defined and determined pursuant to N.J.A.C. 7:8-5.7(c) and (d), respectively, are 50, 75, and 80 percent, 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.

(1) There shall be no direct discharge of stormwater runoff from any point or nonpoint source to any wetland, wetlands transition area, or surface waterbody. In addition, stormwater runoff shall not be directed in such a way as to increase the volume and rate of discharge into any wetland, wetlands transition area, or surface waterbody from that which existed prior to development of the parcel; and. There will be no direct discharge of stormwater runoff onto any wetlands, wetlands transition area, or surface waterbody. (2) To the maximum extent practical, there shall be no direct discharge of stormwater runoff onto farm fields to protect farm crops from damage due to flooding, erosion, and long-term saturation of cultivated crops and cropland. There will be no direct discharge of stormwater runoff onto farm fields. iv. Recharge standards: (1) For all major development, as defined at N.J.A.C. 7:50-2.11, the total runoff volume generated from the net increase in impervious surfaces by a 10-year, 24-hour storm shall be retained and infiltrated onsite; The total runoff volume generated from the net increase in impervious surfaces by a 10-year, 24-hour storm is designed to be retained and infiltrated onsite. All the proposed impervious surfaces are designed to be routed to the proposed infiltration basins. The lowest outlet for all the basins is proposed above the 10-year water surface elevation, to ensure the 10-year storm is fully infiltrated. The lowest outlet and 10-year water surface for each basin is summarized below.

(5) In high pollutant loading areas (HPLA) and areas where stormwater runoff is exposed to source material, as defined at N.J.A.C. 7:8-5.4(b)3i and ii, the following additional water quality standards shall apply: There will not be any HPLC or exposure to source materials onsite. (6) For all major development, as defined at N.J.A.C. 7:50-2.11, stormwater management measures shall be designed to achieve a minimum of 65 percent reduction of the post-construction total nitrogen load from the developed site, including those permanent lawn or turf areas that are specifically intended for active human use as described at N.J.A.C. 7:50-6.24(c)3, in stormwater runoff generated from the water quality design storm. In achieving a minimum 65 ===== PAGE 20 ===== percent reduction of total nitrogen, the design of the site shall include green infrastructure in accordance with the BMP Manual and shall optimize nutrient removal. The minimum 65 percent total nitrogen reduction may be achieved by using a singular stormwater management measure or multiple stormwater management measures in series. The runoff from the site will be treated to a minimum of 65 percent reduction of the post-construction total nitrogen load. The runoff from the area is designed to be routed through bioretention basins or porous pavement and then to infiltration basins. The bioretention basins will reduce the nitrogen load by 30%, and the infiltration basins will reduce the remaining nitrogen load by 50%, for a total reduction of 65%, which meets the required reduction. The porous pavement will reduce the nitrogen load by 50%, and the infiltration basins will reduce the remaining nitrogen load by 50%, for a total reduction of 75%, which meets the required reduction. Runoff from roof areas will be piped directly into subsurface infiltration basins. In accordance with N.J.A.C. 7:8-5.5(b) 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 design storm by eighty percent TSS removal of the anticipated load, expressed as an annual average for the stormwater runoff from the net increase of motor vehicle surface. The site has a total proposed motor vehicle surface of 0.79 acres. The roads, driveways, and lawn area drain into bioretention basins or porous pavement (80% TSS removal) and then subsurface infiltration basins (80% TSS removal), which will act in series and provide a combined 96% TSS removal. v. Stormwater management measure design, siting and construction standards: (1) Stormwater management measures designed to infiltrate stormwater shall be designed, constructed, and maintained to provide a minimum separation of at least two feet between the elevation of the lowest point of infiltration and the seasonal high water table; The stormwater management measures will provide a minimum separation of at least two feet between the elevation of the lowest point of infiltration and the seasonal high-water table. All the proposed stormwater management infiltration basins have been designed by setting the basin bottom at a minimum of two feet above the seasonal high-water table. The basin bottom and seasonal high-water table elevations for each basin or porous pavement area are included in the Green Infrastructure section below. (2) Stormwater management measures shall be sited in suitable soils verified by testing to have permeability rates between one and 20 inches per hour. A factor of safety of two shall be applied to the soil's permeability rate in determining the measure's design permeability rate. If such soils do not exist on the parcel proposed for development or if it is demonstrated that it is not practical for engineering, environmental, or safety reasons to site the stormwater infiltration measure(s) in such soils, the stormwater infiltration measure(s) may be sited in soils verified by testing to have permeability rates in excess of 20 inches per hour, provided that stormwater is routed through a bioretention system prior to infiltration. Said bioretention system shall be designed, installed and maintained in accordance with the New Jersey Stormwater Best Management Practices Manual; ===== PAGE 21 ===== Stormwater Management Report South Hope Chapel Rd. Subdivision Project #23184 A factor of safety of two has been applied to the soil's permeability rate. The majority of the site has soils with permeability which exceeds 20 in/hr. Therefore, it is not possible to site the proposed stormwater measures in areas with tested permeability of between 1-20 in/hr. Per the CMP, infiltration measure(s) may be sited in soils verified by testing to have permeability rates in excess of 20 inches per hour, provided that stormwater is routed through a bioretention system prior to infiltration. The majority of the site runoff to the basins will be pretreated using bioretention basins prior to infiltration. The bioretention basins have been designed in accordance with the New Jersey Stormwater Best Management Practices Manual. In areas where it is not practical to route through bioretention, and instead is routed through porous pavement, it is proposed to replace 36" of soil below the basin with K4 soils with a permeability rate of up to 20 in/hr (for Subsurface Infiltration Basin 3), in accordance with guidance received from the Commission. The replacement soil will extend up the sides of the basin to the elevation of the lowest outlet. (3) For all major development, as defined at N.J.A.C. 7:50-2.11, groundwater mounding analysis shall be required for purposes of assessing the hydraulic impacts of mounding of the water table resulting from infiltration of stormwater runoff from the maximum storm designed for infiltration. The mounding analysis shall provide details and supporting documentation on the methodology used. Groundwater mounds shall not cause stormwater or groundwater to breakout to the land surface or cause adverse impacts to adjacent water bodies, wetlands, or subsurface structures, including, but not limited to basements and septic systems. Where the mounding analysis identifies adverse impacts, the stormwater management measure shall be redesigned or relocated, as appropriate; Groundwater mounding analysis has been conducted for all proposed infiltration basins on site using the USGS Hantush spreadsheet in accordance with NJDEP BMP Manual Chapter 13. The proposed GI has been modeled using infiltration for all storm events. Therefore, the groundwater mounding analysis has been performed for the future 100-year infiltration volume as calculated by HydroCAD. The results of the analysis confirm that the groundwater mounds will not impact the function of the basin or have any impact to subsurface structures. As the groundwater mounding for the 100-year infiltration volume will not cause any adverse effects, mounding for the smaller storms will also not cause any adverse effects.

Subdivision Project #23184 (4) The use of stormwater management measures that are smaller in size and distributed spatially throughout a parcel, rather than the use of a single, larger stormwater management measure, shall be required; The project proposes multiple small scale stormwater management measures which are distributed throughout the site which each drain less than 2.5 acres. (5) Methods of treating stormwater prior to entering any stormwater management measure shall be incorporated into the design of the stormwater management measure to the maximum extent practical; The stormwater runoff will be pretreated. All of the site runoff to the small-scale infiltration basins will be pretreated using bioretention basins or porous pavement. All the roof runoff to the small-scale infiltration basins will be pretreated with leaf screens. ## County ROW Improvements South Hope Chapel Road is proposed to be widened along the project frontage. The proposed widening will add 6,402.44 sf of additional asphalt pavement and 1,861.45 sf of additional sidewalk on South Hope Chapel Road. An underground basin consisting of 60 linear feet of 24" perforated HDPE in South Hope Chapel Road is proposed to manage the increase in runoff. These basins are designed to fully infiltrate the increased runoff occurring during a 2-year storm, as per the County requirements. ## Conclusion The proposed development and stormwater management measures have been designed in compliance with the applicable Pinelands Commission regulations with regard to stormwater quantity, quality, and groundwater recharge requirements. ===== PAGE 23 ===== Stormwater Management Report South Hope Chapel Rd.

===== PAGE 27 ===== ## Description Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. ## Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff: None Specified Tie-break Rule: Higher ===== PAGE 28 ===== Stormwater Management Report South Hope Chapel Rd.
