Page 1 The current owner is proposing to convert the existing golf course property into City conservation land and five single family lots. The Berkshire Design Group has prepared a Stormwater Management and Erosion and Sedimentation Control Plan for the site, in compliance with the Massachusetts Stormwater Handbook and the Code of the City of Northampton. This report documents the proposed Stormwater Management Plan and that plan’s compliance with those standards. I. Introduction The proposed project includes creating five single family house lots and conservation land within the 117.8 acre Pine Grove golf course property. The single-family home lots of 1.8 to 3.3 acres in size are planned off of Old Wilson Road on the west side of the property. The remaining 105 acres to the north and east will be sold to the City of Northampton for conservation purposes. The project location is shown in Figure 1. The work includes demolition and removal of several existing golf course buildings, paved areas and drainage infrastructure and selective clearing of the woods to construct the new homes and driveways. The existing access drive for the clubhouse is proposed to serve as the common drive for some of the lots. Additional driveway length will be required to access some of the house lots. The proposed conservation area includes deciduous and coniferous woodlands, open space (golf course mowed grass, sand traps and greens), a shrub swamp and marsh meadow, a stream and pond. All runoff from the area is directed to the stream flowing south at the center of the golf course property. The stream is a tributary to the Manhan river. The land slopes steeply toward the stream to the east and west. The development of five single family homes will not significantly alter the existing drainage patterns. Soil Data NRCS Soil Survey The NRCS Soil Survey reports that the majority of the study area consists of fine sandy loam and silt loam soils of Hydrologic Soil Group (HSG) C and D. To the northeast and southwest there are pockets of HSG A and B. The NRCS Soil Report for the site is attached in Appendix A. Test pits were completed at several locations along the west side of the property within the proposed lots. The results of the test pits are included as Appendix B. Soils within the eight test pits included fill and fine sandy loam in the upper strata, followed with fine sand and silt loam, loamy sand and even coarse sand in the lower depths. Estimated high groundwater varied from 20” (test pit #1) to 112” (test pit #7) with the average depth appearing to be 50 to 60 inches (see Figure A, appendix B).

Existing Conditions For this project, the property line is used as the drainage study area along the north, east and west. To the west, the adjacent drainage area is included since it contributes directly to the proposed drainage system for the proposed homes. An existing conditions plan with soil type boundaries and extent, is shown on Figure 2. Figure 3 illustrates existing impervious areas, open space (golf course) and wooded areas. The majority of the study area (88 acres) is open space comprised of A, C and D soils. The wooded area (33.5 acres) includes all soil types. Impervious areas calculated for existing conditions include approximately 4.1 acres of buildings, roads, parking areas, and pathways. Pathways within the golf course area contributing to the impervious area were estimated from aerials. Runoff from all portions of the drainage area is either channeled or sheet flows to the stream at the center which flows south towards the Manhan river. For purposes of this study, the analysis point is where the stream intersects the property line at the south end of the property. Existing drainage systems include a stone trench along the existing golf course access road and parking. The western portion of the flow within this gravel trench is channeled to a catch basin within Old Wilson road. The piped system within old Wilson road daylights about 400’ south of the golf course access road. At that point the runoff appears to flow north and east in a ditch and onto the golf course as sheet flow. The eastern portion of the gravel trench flow enters a catch basin, pipe and drainage manhole system which currently discharges to the pond. Other catch basins are located within the parking lot and along pathways adjacent to the club house. All of these catch basins appear to be collected and drained to the on-site pond. III. Proposed Conditions Proposed conditions are shown on Figures 4, 5 and 6. Figure 4 illustrates the change in impervious area for the site. No change is shown for the pathways within the golf course although these may be removed or allowed to deteriorate to gravel. Conservatively, these impervious areas are included within the proposed condition model. Other impervious areas including the clubhouse, maintenance building and extensive asphalt parking areas are proposed to be removed and areas restored to woods or meadow. The golf course was assumed to revert to a meadow cover type from open space mowed lawn and trees. Based on the City’s proposed conservation strategy, overall impervious area decreased to 3.4 acres. Proposed drainage improvements are designed to use a portion of the existing drainage infrastructure and add swales, drainage culverts and level spreaders to maintain existing drainage patterns (see Figures 5 and 6 for detailed drainage). The gravel trench system along the access road will remain along with the catch basin at Wilson Road. The catch basin at the driveway intersection and the drainage system under the road and within the flag lot will be upgraded to a catch basin with sump and a 15” HDPE with an outlet to a level spreader. Other drainage improvements include stone/riprap lined swales along the steeper driveways and grass swales on flatter terrain. Two culverts and level spreaders within lots 2 and 3 allow runoff from upstream drainage areas to cross under proposed driveways. Similarly, a culvert under the flag lot driveway followed with a grass swale/filter strip maintains existing drainage patterns. Pine Grove Golf Course -254 Old Wilson Road November 20, 2019 Northampton, Massachusetts Stormwater Management Report The Berkshire Design Group, Inc. Page 3 The decrease in impervious area, the construction of the five single family homes and the conversion of the golf course to conservation land results in a decrease in runoff. The proposed drainage design focuses on conveying runoff and maintaining existing drainage patterns. IV. Calculations and Design Water Quantity Drainage calculations were performed on HydroCAD Stormwater Modeling System version 10.0 using Soil Conservation Service (SCS) TR-20 methodology. The SCS method is based on rainfall observations, which were used to develop the Intensity-Duration-Frequency relationship, or IDF curve. The mass curve is a dimensionless distribution of rainfall over time, which indicates the fraction of the rainfall event that occurs at a given time within a 24-hour precipitation event. This synthetic distribution develops peak rates for storms of varying duration and intensities. The SCS distribution provides a cumulative rainfall at any point in time and allows volume-dependent routing runoff calculations to occur. The watershed boundary for calculation purposes is the property boundary and an additional area to the west which contributes to the drainage design of the five single-family lots. The curve numbers (CNs) and times of concentration for the existing and proposed areas are based on the soil type and the existing and proposed cover conditions at the site. Design storm intensity is based on data from the Northeast Regional Climate Center (NRCC) extreme precipitation tables, which provide a conservative design accounting for changes in climate and increases in storm intensity over time. Calculations were performed for the 2-, 10-, and 100-year frequency storms under existing and proposed conditions. The results of the calculations are presented in Table 1 below. Appendix C presents the HydroCAD output reports. Table 1. Runoff Summary Table for Conservation Area Condition & Point of Analysis 2-Year Storm 3.05” 10-Year Storm 4.50” 100-Year Storm 7.62” Peak Flow Rate (cfs) Peak Flow Rate (cfs) Peak Flow Rate (cfs) Existing 80.20 168.93 398.97 Proposed 67.87 150.22 369.44 The model shows a decrease in peak stormwater runoff leaving the study area for each design storm. The decrease in impervious cover of the proposed development and the conversion of the golf course “open space” cover to meadow results in a significant decrease in peak stormwater runoff from the area. Water Quality The re-development of the site results in a decrease in the water quality impact based on the decrease in impervious area. The design of the proposed drainage includes riprap and grass Pine Grove Golf Course -254 Old Wilson Road November 20, 2019 Northampton, Massachusetts Stormwater Management Report The Berkshire Design Group, Inc. Page 4 swales/filter strips, sheet flow to forested or future meadow areas and dry wells for roof area runoff infiltration. The drainage system currently in place and discharging directly to the golf course pond will be eliminated. A new catch basin with a sump will be constructed and the formerly piped flow will be daylighted, discharged over a level spreader and allowed to sheet flow into the conservation land. Water quality will be enhanced by the up to date catch basin and the level spreader/sheet flow. All proposed driveways include a cross slope to allow runoff to sheet flow off. On the steeper driveway to Lot 4, a curb is included on the side of the driveway to promote even sheet flow. The sheet flow to vegetated areas will provide water quality treatment of driveway runoff. Although the vegetated areas are steeply sloped in many areas, the distance to the stream exceeds 500 feet and runoff travels through wooded and open space meadow areas. The 700-gallon dry wells proposed for each dwelling will provide for infiltration of roof runoff. The proposed dry well volume provides storage for approximately 1/2” of runoff from each proposed house. Runoff Conveyance along driveways The driveways generally follow existing cart paths or driveway alignments to minimize disturbance. Existing riprap swale conveyances will be re-used for the main driveway to Lots 2-4. A new catch basin and 15” pipe system will be used to convey the runoff to a level spreader at the back of the flag lot. To convey runoff across the driveway to lots 3/4, two 12” culverts are proposed with level spreaders at the outfall (see Figure 5). As previously mentioned, the existing system draining to the pond will be daylighted. The driveway to the flag lot includes a conveyance culvert which outlets into a wide grass filter strip. The filter strip will also accommodate overland flow from the driveway. As is standard practice, the 25-year storm has been used as the design storm for conveyances. The rainfall value for the 25-year storm has been obtained from NRCC’s Extreme precipitation table for the site location. The 25-year storm 24-hour precipitation is 5.50 inches. The extreme precipitation table considers climate change trends on a regional basis. Figure 6 provides information on the drainage area size, 25-year flow and pipe capacity for all proposed culverts. Erosion & Sedimentation Control The project plan set includes provisions for erosion control during construction. Driveway and home construction is expected to proceed with limited disturbance sufficient to install the driveways and homes amongst the trees. Straw wattles are proposed for down-slope protection for ease of transport, installation and removal. At culvert and house locations, a silt fence barrier is proposed in addition to the straw wattles. The silt fence at these locations may be replaced with an organic filter berm which could be constructed from cleared trees. Soil stockpiles will be located away from drainage conveyances. A silt fence shall be placed around the perimeter of the stockpiles.

MADEP Stormwater Standards Compliance The following section details how the project will meet the DEP Stormwater Management Policy’s ten stormwater management standards. Standard 1 - Untreated Stormwater Discharge Driveway runoff is designed to sheet flow over existing vegetated pervious areas which include woodlands and open space/future meadow. The proposed culverts convey runoff from existing woodlands and open space areas and include level spreaders to promote sheet flow. The proposed site improvements do not discharge runoff directly to wetland areas. Standard 2 - Post-Development Peak Discharge Rates Calculated post-development peak discharge rates are reduced from pre-development peak discharge rates. These results are discussed in detail under “Peak Runoff Rate” in Section IV, above. Standard 3 - Recharge to Groundwater The plan reduces impervious area by 0.7 acres and decreases the required recharge volume over existing conditions. Infiltration is provided to the maximum extent practicable based on the decreased impervious area and C and D on-site soils which preclude large scale infiltration. Infiltration is provided for rooftop runoff. Five 700-gallon dry wells are proposed for the project. Some infiltration will also take place at the level spreader outlets where a stone basin has been made part of the design. Runoff from driveways also qualifies as “disconnected impervious areas” which qualify for LID Credit #3. Sheet flow extends more than 500 linear feet to the existing stream and wetlands. Standard 4 – Water Quality The project includes the conversion of existing impervious area to pervious re-planted areas. Overall there is a decrease in impervious area of 0.7 acres and TSS removal is addressed to the maximum extent practicable given the steep slopes and C and D soils. The design emphasizes sheet flow over vegetated areas to minimize concentrating flows and the resulting potential erosion. Swales and level spreaders are proposed to reduce velocity and encourage sheet flow. A grass swale/filter strip is included on the flag lot to convey upstream runoff and driveway runoff to the conservation land. The catch basin on Lot 2 is proposed for replacement with a new catch basin with a sump and hood. This catch basin collects the largest drainage area west of the site for conveyance to the conservation land. This project includes parameters of LID credit No. 3 which provides water quality credit for sheet flow from impervious flow path lengths of 75 feet or less. The proposed driveways are all crossed sloped to provide for sheet flow. Further discussion of this standard is included under “Water Quality” in Section IV.

Page 6 Standard 5 - Higher Potential Pollutant Loads The proposed project is not expected to yield high potential pollutant loads. Standard 6 - Protection of Critical Areas The project is not located within a Zone II or interim Wellhead Protection Area of a public water supply nor does it discharge to a critical area. Standard 7 - Redevelopment Projects This project is a redevelopment project. Impervious area over the project decreases from 4.1 acres to 3.4 acres. Standard 8 - Erosion/Sediment Control A proposed Erosion & Sediment Control Plan has been developed, and is shown in the plan set. A full Stormwater Pollution Prevention Plan will be developed by the contractor prior to any disturbance of the site. Standard 9 - Operation/Maintenance Plan An Operation and Maintenance Plan for the proposed project is included in Appendix E. It includes general controls for construction and long term maintenance of the stormwater management system. Standard 10 – Prohibition of Illicit Discharges An Illicit Discharge Compliance Statement will be submitted prior to the discharge of any stormwater to post-construction practices.

Appendix A – NRCS Soil Report United States Department of Agriculture A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Hampshire County, Massachusetts, Central Part Pine Grove Golf Course Natural Resources Conservation Service November 7, 2019 Preface Soil 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.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

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. Custom Soil Resource Report 9 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.

Appendix E – Stormwater Management System – Operation & Maintenance Plan Pine Grove Golf Course – 254 Old Wilson Road November 20, 2019 Northampton, Massachusetts Stormwater Management Report The Berkshire Design Group, Inc. Page 1 Stormwater Management System Operation & Maintenance Plan During Construction The Contractor shall be responsible for inspection and maintenance during construction. At all times, siltation fabric fencing, stakes and straw bales/wattles, sufficient to construct a sedimentation control barrier a minimum of 50 feet long, shall be stockpiled on the site in order to repair established barriers which may be damaged or breached. An inspection of all erosion control and stormwater management systems shall be conducted by the Contractor at least once a week and during all rain storms until the completion of construction. In case of any noted breach or failure, the Contractor shall immediately make appropriate repairs to any erosion control system and notify the engineer of any problems involving stormwater management systems. A rain storm shall be defined as any of the following: · A storm in which rain is predicted to last for twelve consecutive hours or more. · A storm for which a flash flood watch or warning is issued. · A single storm predicted to have a cumulative rainfall of greater than one-half inch. · A storm not meeting the previous three thresholds but which would mark a third consecutive day of measurable rainfall. The Contractor shall also inspect the erosion control and stormwater management systems at times of significant increase in surface water runoff due to rapid thawing when the risk of failure of erosion control measures is elevated. In such instances as remedial action is necessary, the Contractor shall repair any and all significant deficiencies in erosion control systems within two days. The Northampton Department of Public Works shall be notified of any significant failure of stormwater management systems or erosion and sediment control measures, and shall be notified of any release of pollutants to a water body (stream, brook, pond, etc.). The Contractor shall remove the sediment from behind the fence of the sedimentation control barrier when the accumulated sediment has reached one-half of the original installed height of the barrier. This project requires a NPDES General Permit for Stormwater Discharges from Construction Activities. Contractor and Owner are responsible for finalizing a Stormwater Pollution Prevention Plan (SWPPP) and filing for the NDPES permit prior to the start of construction. All clearing, grading, drainage, construction, and development shall be conducted in strict accordance with the SWPPP. Pine Grove Golf Course – 254 Old Wilson Road November 20, 2019 Northampton, Massachusetts Stormwater Management Report The Berkshire Design Group, Inc. Page 2 Post-Construction Stormwater Management System Owner: Homeowner’s Association Party Responsible for Operation & Maintenance: Homeowner’s Association Inspection & Maintenance Schedule: 1) Driveway Sweeping Regular sweeping will prevent sediment from entering the stormwater system and will reduce maintenance of catch basins, pipes and outlets. Sweeping is not required under this plan; however, sweeping twice per year (including after the spring snow melt) is recommended. Mechanical sweeping, while preferred, is not required. Manual sweeping/raking will benefit the stormwater system and reduce maintenance. 2) Grass and Stone Swales The Pine Grove development includes stone and grass swales to convey stormwater to culverts and level spreaders. Inspect swales or conveyances multiple times in the first few months after construction and twice per year thereafter. Look for signs of erosion and, if found, repair immediately. Swales shall be mowed at least once per year to prevent the growth of shrubs or trees but may be mowed more often at the discretion of the property owner. 3) Storm Drain Outlet Protection The integrity of riprap outlet armoring shall be inspected twice per year for signs of dislodged stones or erosion at the perimeter of the apron. Any damage shall be repaired to return the apron to the condition shown in the contract documents. While some growth of herbaceous plants is expected, regular trimming is required to prevent growth from restricting the free flow of water across the apron. 4) Level Lip Spreader Inspect level lip spreaders multiple times in the first few months after construction and twice per year thereafter. Clean out any debris or sediment as needed. Note and repair any erosion or low spots at the ends of the curb of the spreader. It is recommended that sediment removal, if any, be performed after the completion of the spring snow melt. 5) Catch basins Structures shall be inspected four times per year and cleaned if sediment build up exceeds 6” but no less than every 2 years. Oil and sediments shall be removed and disposed of in accordance with local, state and federal guidelines and regulations. In the case of an oil or bulk Pine Grove Golf Course – 254 Old Wilson Road November 20, 2019 Northampton, Massachusetts Stormwater Management Report The Berkshire Design Group, Inc. Page 3 pollutant release, the system must be cleaned immediately following the spill and the proper authorities notified. 6) Dry Wells Dry wells should be inspected to ensure that they dewater after rainfall stops. Because of relatively shallow groundwater, dry wells may retain water during times of high groundwater (late winter through spring). Therefore, inspections should occur in late summer/early fall. Water levels should be observed through the observation port in the top of the dry wells after an intense rainfall. Water should fully infiltrate within 72 hours after rainfall stops. If water does not fully infiltrate an engineer or other competent professional should be engaged for further investigation. Inspection and maintenance of dry wells is the responsibility of the individual homeowners; therefore, dry well maintenance is not a formal requirement of this O&M Plan.

Introduction Important: When filling out forms on the computer, use only the tab key to move your cursor - do not use the return key. A Stormwater Report must be submitted with the Notice of Intent permit application to document compliance with the Stormwater Management Standards. The following checklist is NOT a substitute for the Stormwater Report (which should provide more substantive and detailed information) but is offered here as a tool to help the applicant organize their Stormwater Management documentation for their Report and for the reviewer to assess this information in a consistent format. As noted in the Checklist, the Stormwater Report must contain the engineering computations and supporting information set forth in Volume 3 of the Massachusetts Stormwater Handbook. The Stormwater Report must be prepared and certified by a Registered Professional Engineer (RPE) licensed in the Commonwealth. The Stormwater Report must include: · The Stormwater Checklist completed and stamped by a Registered Professional Engineer (see page 2) that certifies that the Stormwater Report contains all required submittals.1 This Checklist is to be used as the cover for the completed Stormwater Report. · Applicant/Project Name · Project Address · Name of Firm and Registered Professional Engineer that prepared the Report · Long-Term Pollution Prevention Plan required by Standards 4-6 · Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan required by Standard 82 · Operation and Maintenance Plan required by Standard 9 In addition to all plans and supporting information, the Stormwater Report must include a brief narrative describing stormwater management practices, including environmentally sensitive site design and LID techniques, along with a diagram depicting runoff through the proposed BMP treatment train. Plans are required to show existing and proposed conditions, identify all wetland resource areas, NRCS soil types, critical areas, Land Uses with Higher Potential Pollutant Loads (LUHPPL), and any areas on the site where infiltration rate is greater than 2.4 inches per hour. The Plans shall identify the drainage areas for both existing and proposed conditions at a scale that enables verification of supporting calculations. As noted in the Checklist, the Stormwater Management Report shall document compliance with each of the Stormwater Management Standards as provided in the Massachusetts Stormwater Handbook. The soils evaluation and calculations shall be done using the methodologies set forth in Volume 3 of the Massachusetts Stormwater Handbook. To ensure that the Stormwater Report is complete, applicants are required to fill in the Stormwater Report Checklist by checking the box to indicate that the specified information has been included in the Stormwater Report. If any of the information specified in the checklist has not been submitted, the applicant must provide an explanation. The completed Stormwater Report Checklist and Certification 1 The Stormwater Report may also include the Illicit Discharge Compliance Statement required by Standard 10. If not included in the Stormwater Report, the Illicit Discharge Compliance Statement must be submitted prior to the discharge of stormwater runoff to the post-construction best management practices. 2 For some complex projects, it may not be possible to include the Construction Period Erosion and Sedimentation Control Plan in the Stormwater Report. In that event, the issuing authority has the discretion to issue an Order of Conditions that approves the project and includes a condition requiring the proponent to submit the Construction Period Erosion and Sedimentation Control Plan before commencing any land disturbance activity on the site.
