Sincerely, Rachel Rachel Loeffler, RLA, ASLA, Principal The Berkshire Design Group 4 Allen Place Northampton, MA 01060 413‐582‐7000 COVER LETTER 02.25.2021 Sarah LaValley Conservation, Preservation and Land Use Planner Northampton Office of Planning and Sustainability 210 Main Street Northampton, MA 01060 Re: Notice of Intent Application 176 Turkey Hill Road Northampton, MA Parcel 34‐016 Owners: Linda Doucette‐Ashman and Harvey Ashman Dear Sarah and Members of the Conservation Commission, On behalf of the owners of the property at 176 Turkey Hill Road, we respectfully submit this Notice of Intent Application in connection with the removal of an existing single‐family home, construction of a new single‐family home and redevelopment of the existing driveway in the vicinity of wetlands previously delineated at a hearing of this Commission on October 22, 2020. A Transmittal outlining the application materials submitted is attached as part of this package. In accordance with MA310 CMR and Northampton Chapter 337 Wetlands Protection, we are coming to the Conservation Commission for review of the proposed work taking place within the outer 50’‐100’ Buffer Zone, and the outer 100’‐200’ Riverfront Area. The following narrative within this document includes a description of the project background, and a description of the existing site conditions as well as a narrative outlining the proposed work. Background The owners purchased the property on June 18, 2020 after searching for a home in the Northampton area for more than two years. The property is a 40.3‐acre lot with an existing Sarah LaValley Conservation, Preservation and Land Use Planner Northampton Office of Planning and Sustainability 210 Main Street, Northampton, MA 01060 The Berkshire Design Group 176 Turkey Hill Road Notice of Intent Conservation Commission │ Page 2 COVER LETTER single‐family home, sheds, lawn and driveway. The driveway extends approximately 500’ from Turkey Hill Road to an upland plateau where the single‐family home, sheds and lawn are located (~1.8 acres). The balance of the property is wooded. Trees were cut down in the area of the upland plateau over a period of years, leaving tree stumps and seventeen debris piles in the area of the driveway and plateau (see accompanying document entitled 176 Turkey Hill Road: Documenting Existing Degraded Conditions, Fall 2020). There is one enclosed shed, two open shed structures and a small shack built on pallets in various locations along the upland plateau. Google earth photos reveal a structure immediately adjacent to the wetlands area which was removed before the house was put on the market in 2019 (See photograph of first page of RDA application). There is an existing well head on the western side of the house and a private septic system on the eastern side of the house. At the point where the driveway meets the upland plateau, there is a large parking and turnaround area at the front of the existing house. There are two old logging trails at separate points along the western side of the upland plateau that continue towards the western portion of the property and one old logging trail near the top of the driveway, also on the western side and continuing towards the western portion of the property. The 40.3 Parcel at 176 Turkey Hill Road is designated with both the Rural Residential (RR) and Special Conservancy (SC) Zones according to the Northampton Zoning Map and Northampton Assessor’s Map. This project will occur completely within the RR zone. The upper plateau and remaining 39.75 acres of the parcel fall within the RR zone (i.e., 98.8% of the parcel). Only 1.2% of the site falls within the SC Zone, of which the majority of the SC zone is wooded, steeply sloped and adjacent to Turkey Hill Road. This project includes the following: (1) construction of a new, energy efficient, single family home and garage on the upland plateau in the area of the existing house, lawn and sheds (note: a small portion of the new home will be in the 50’ to 100’ buffer zone existing lawn area, positioned there to maximize southern roof exposure for solar panels and minimize tree removal); (2) demolition of the existing house and two open shed structures on the upland plateau built in 1984 per City of Northampton tax records (note: the existing house, one of the open shed structures, driveway and parking areas will be removed from the buffer zones); and (3) redevelopment of the existing driveway with improved stormwater management measures (note: the lower portion of the driveway is within a 50’ – 100’ wetland buffer zone and the 100’ ‐ 200’ of the Riverfront Area delineated on the other side of Turkey Hill Road). This project will not have a significant or cumulative detrimental effect upon Northampton resource area values in accordance Northampton Chapter 337, Wetlands Protection. Sarah LaValley Conservation, Preservation and Land Use Planner Northampton Office of Planning and Sustainability 210 Main Street, Northampton, MA 01060 The Berkshire Design Group 176 Turkey Hill Road Notice of Intent Conservation Commission │ Page 3 COVER LETTER This property has degraded, disturbed and developed areas as noted above. This project will improve the property’s existing degraded and developed areas. (Sec. 337‐10E(2)(h)[1]). None of the proposed work categorized as degraded will be located closer to the resource area than existing degraded conditions on the property. (Sec. 337‐10E(2)(h)[2]). The project will be located completely outside of the resource area. The project is sited to minimize its impact on the buffer zones while still providing emergency vehicle access, preserving access for future solar and minimizing tree removal. (Sec. 337‐10E(2)(h)[3]). Based upon the previous submitted delineations, reviewed by this Commission in October 2020, the project team has mapped 81,612 SF of land falling within the outer 50’‐100’ Wetland Buffer zone. The project will utilize 17.56% of the lot’s allotted 20% of the 50’ – 100’ buffer zone. A significant portion of this work involves placement of utilities, grading of existing lawn areas for access, and accommodating stormwater management on site associated with the new home and driveway placement. The area around the new home will maintain lawn up to the resource area, as is the current situation. Of the 17.56% disturbance only 4.73% of disturbance within the 50’ to 100’ buffer will be due to the construction of permanent impervious surfaces (a portion of the house and the emergency turn around area of the drive). The remaining 12.8% of disturbed areas will long‐term remain open landscape or planted areas and are categorized as disturbed do to regrading required for stormwater management or access. The project will not have a significant adverse impact on the resource area. (Sec. 337‐10E(1)(a)). The project work area on the upland plateau located in the buffer zone will take place within the footprint of the existing house, driveway, parking area, shed location, previously cleared areas by prior owner and existing lawns. The existing driveway and house were built in 1984. Per 310 CMR 10.58(5), the driveway replacement work qualifies as Redevelopment Within Previously Developed Riverfront Areas. The proposed work in this area of the driveway is repair, paving and creating a stormwater bio retention basin that is a component of the project’s stormwater management plan. Roughly 134 Linear feet of the existing driveway falls within the outer 100’‐200’ Riverfront Area. The existing drive represents a degraded percentage of the total riverfront area at 3.68%. The drive will be shifted 3‐4 feet to the east away from the base of a steep slope to improve drainage and sight lines at Turkey Hill Road. The driveway improvements include repaving the drive, evening out its grades, and providing a biorentention structure near the base of the drive for water quality. The increase of area of disturbance within the Riverfront Area increases by 1,339.79 SF, this should be noted is for a benefit to surrounding areas receiving stormwater runoff from the site. The total proposed disturbance within the Riverfront Area is 5.62%, below the incremental 10% of additional disturbance allowed.

A special permit application is required to allow for driveway improvements on the project site. And any project requiring special permits and/ or site plans will need to comply with the Northampton Tree Ordinance ************************************************************************** + Application form online OWNER: Harvey Ashman and Linda Doucette‐ Ashman 49 Woodstone Circle, Short Hills, NJ 07078 APPLICANT: Not same as owner Berkshire Design Group (Representative) 4 Allen Place Northampton MA 01060 413‐582‐7000 rachel@berkshiredesign.com How many lots 1 Street Number of project: 176 Street Name of Project: Turkey Hill Road City and Zipcode: Northampton 01062 Registry of deeds info: Deed Book 13666, Page 341 Plan Book 77, Page 97 Zoning districts, and overlay districts SC & RR Assessors map, block, and lot number, 34 016 001 Permit Type: Planning Board Special Permit with Site Plan, Notice of Intent, City of Northampton Stormwater Permit Existing use of your structure or property: Existing single‐family house with outbuildings and driveway Proposed use of your structure or property: Work associated with demolition of existing single‐family house and associated sheds, construction of a new single‐family house and garage; and redevelopment of existing degraded driveway. Describe planned use, your proposed project and your request in DETAIL (include relevant sections of regulations) AND whether you have discussed this with your neighbors Project overview: Project seeks to replace the existing single‐family home and driveway at 176 Turkey Hill Road with a new energy efficient home and improved driveway. The project is an as‐of‐right use and meets dimensional regulations for the RR zone (Section 350 Attachment 4) and the SC zone (Section 350 Attachment 18) for Lot size, frontage, setbacks, building height, and open space requirements. Please note that the proposed project is not within the small portion of the property’s frontage along Turkey Hill Road that is within the SC zone. The parcel is a 40.3 acre/ 1,755,468 SF parcel, far exceeding the 80,000 SF min for projects within the RR and SC zones which rely on private sewer and water. The parcel’s frontage will remain the same, 611.62 LF, complying with the min frontage for the RR Zone of 175 LF. The project respects dimensional requirements providing greater than the min setbacks (403 front, 395/75 sides, 591 rear) proposed vs (40 front,20/20 sides ,50 rear) min. The proposed work also complies with the min open space requirements for the RR Zone, as the proposed project maintains roughly 99% open space, well above the min 80% required. The project also does not exceed the max building height for this zone. The proposed house is a two‐story house with a height of 30.4 LF from the average grade to mid‐gable. The proposed house makes a footprint of roughly 4,448 SF inclusive of covered porches. In addition, the project proposes an attached garage of 1,437 SF. There is an accommodation of up to four parking spaces in front of the parking garage. The proposed home and garage complies with all existing zoning and requirements. The existing parcel is characterized by steep slopes between Turkey Hill and a level plateau roughly 500 LF into the interior of the parcel. This level plateau is the area where the project seeks to work, redeveloping the existing disturbed area. The rest of the parcel slopes steeply up or down to the West, South, and East. The existing drive extends southward off an existing curb cut at Turkey Hill Road and roughly follows the existing grades of the site. An existing riprap swale collects water from the drive and directs it to the road. Given the existing grades and surrounding slopes, the existing driveway exceeds the slopes outlined under section 350‐8.8 (P). 350‐8.8 (P) Parking and Loading Space Standards No portion of individual, private driveways shall exceed a slope of 10% with switchbacks and turns reasonable for emergency vehicle access. However, driveways between 10% and a maximum of 12% on south‐facing slopes with no curves may be approved by the Office of Planning and Development in consultation with the Fire Department when it is determined that no public safety issues will be created with such driveways. However, the Planning Board may allow steeper grades by special permit, when it is determined that no public safety issues will be created with such driveways. The existing driveway at Turkey Hill varies from 12% to 16% along its length and is rutted with water runoff coming from the roof of the existing house. The gravel drive’s surface has degraded. In addition, two of the existing culverts (midway up the drive) have caved in further exacerbating drainage issues. The lower 134 LF of the driveway falls within the Riverfront Area. Stormwater strategies were considered to deal with any additional runoff from the upper development while minimizing the scope of work and regrading to manage stormwater within the 200’ Riverfront Area. This scope is outlined in the Notice of Intent Application Narrative and Materials. After review with the City Engineer, the project classifies the lower driveway work as redevelopment as there is not an increase in impervious surface. The project proposes to regrade the driveway, pave it with asphalt, even out the grades along its length, and sheet flow towards the drainage swale to its east. The culvert underneath the drive will be rebuilt. The upper driveway widths widen to accommodate emergency vehicle access and turn‐a‐around. The stormwater flowing from the upper driveway will be managed by two side‐by‐side basins at the top of the driveway. The increase in impervious surface within the upper portion of the limit of disturbance is 100% balanced pre and post development through the use of the aforementioned basins and the subsurface infiltration and level spreader to the south of the new house. The project team has prepared a detailed stormwater report and calculations to demonstrate how this is achieved. 350‐8.8 (Q) Parking and Loading Space Standards . For all driveways with grades greater than 8% or longer than 500 feet and which do not result in total site disturbance of one acre or more triggering a Department of Public Works stormwater permit, a drainage plan shall be submitted to the Office of Planning and Development for review and approval. The existing driveway is roughly 515’ LF and provides a T intersection at the top of drive for turning around. The proposed driveway is roughly 560’ and includes a dedicated turn‐a‐round area for emergency vehicles. Berkshire Design has coordinated with the Fire Department to model the turning movements of the City’s pumper truck within the proposed layout. These diagrams are attached as part of the permit application. Per the City’s review of the zoning application submitted January 26, 2021, the project will be required to pursue a Northampton stormwater permit, a Notice of Intent permit with the Northampton Conservation Commission/ MA DEP, and a stormwater permit with the Northampton DPW. Further, prior to construction, the project will pursue building permits with the City and will submit an EPA NOI SWPPP permit prior to beginning construction. In addition, the project will be submitting a well permit and a septic permit for a new water supply well and the new septic system associated with the redevelopment of the site. As such per section 350‐12.3, Significant Trees, 350‐12.3 (B) No person shall remove any significant tree associated with any site plan approval or any other zoning relief without a site plan approval from the Planning Board (if a site plan approval is otherwise required), or an administrative site plan approval from the Office of Planning and Sustainability if no site plan is otherwise required. And 350‐12.3 (D) (4) Trees that are hazardous due to disease, age, or shallow roots, as determined and confirmed in writing by a certified arborist and reviewed by the City's Tree Warden. The project’s arborist, Charles Mc Carthy, of Arbor & Horticulture Advisor of Belchertown, MA, between September and October 2020 assessed the significant trees within the possible work area that are 20” or greater in caliper. In addition, he identified trees which may be diseased or damaged and pose a life safety risk. All trees reviewed by the arborist were marked in the field with blue tags and numbered. Subsequently these trees were surveyed in the field by Berkshire Design Group and added to the existing survey and integrated into the permit plan sets which accompany this application. Trees to be protected and trees to remain are noted on the plans. Replacement Trees will be provided per section 350‐12.3, E., 1 or 2, or a combination thereof prior to the completion of the project. Existing Trees are identified on the Existing Condition Plans LC 111 and LC 112. Trees slated for removal and protection are located on the Erosion and Demolition Control Plans LC121 and LC 122. Please note that 5 of the trees slated for removal qualify as “Significant trees” per Northampton regulations. These include one (1) qty Hemlock and four (4) qty white pine, totaling a combined caliper of 108.” As Per 337‐10, E. (1) Northampton Wetlands Protection Performance Standards Certain areas 50 feet to 100 feet from wetlands may be suitable for temporary, limited or permanent disturbance as appropriate when the applicant can demonstrate to the Commission's satisfaction that the proposed work, activity or use will not affect wetland values singularly or cumulatively and, by means of a written and plan view assessment, that reasonable alternatives to the proposed work or activity do not exist. (a) The Commission may allow the alteration of up to 20% of the area within the fifty‐foot to one‐hundred‐foot buffer zone on a lot, or up to 2,000 square feet on a lot within a cluster subdivision. This is a total, cumulative allowance for all projects on a lot developed since the City first adopted a wetlands protection ordinance (August 17, 1989). The proposed work must have no significant adverse impact on the resource area, and the applicant must provide evidence deemed sufficient by the Commission that the area being disturbed will not harm the resource area values protected by the law. Between September 2020 and October 2020, Ward Smith, of Wendell Wetland Services, delineated the existing resource areas adjacent to the proposed development area. This delineation continued to the west of the proposed area and included areas across Turkey Hill Road. In addition to wetlands, within 200’ of the parcel, a perennial stream flows west to east beyond the north side of Turkey Hill Road. The project area is separated from the stream by a 4’ high landscape earthen berm, and existing grades indicate water running off the parcel’s existing driveway sheet flows into the southern edge of Turkey Hill Road to the east. Ward Smith delineated both the edge of wetlands and the top of bank These delineations were presented, via an RDA, to the Conservation Commission on October 22, 2020. The owners of 176 Turkey Hill Road have spoken with their neighbors at 218 Turkey Hill Road prior to this submission. + Application fee ($325) + Full Permit Plan Set 2 copies hard copy mailed/ dropped off at City Hall due to covid: + Erosion Control Demolition Plan + Existing Conditions Plans (grading, property info, vegetation, and utilities) + Proposed Plans (grading, drainage, utilities, layout, materials, planting) + Building elevations and floor plans for reference + Additional Permit Set and application to the City Clerk Will deliver at time of delivery of plan sets. + Installation of Public Hearing Sign (Yellow sign with notice) During Covid‐ the City may elect to place the sign themselves along the frontage of the parcel.

The project will be require to submit an EPA NOI SWPPP online prior to the start of construction. The project is outside any state designated Natural Heritage Rare Species Habitat as indicated on Oliver GIS’s online viewer. The project is outside the 100‐year and 500‐year floodplain per the online FEMA firmette for this parcel. The project is outside Zone 1, Zone 2, and IWPA wellhead protection zones. The project has an existing private well at the top of the existing driveway. A new well is proposed further to the south of the developed area to protect the water quality of the well supply. The project has successfully perc’d two locations for a future private sewer system within the developed area and is greater than 100’ from the proposed private water supply well. The project will pursue a septic permit and a well permit through the City of Northampton Board of Health. A Mass Historic Project Notification Form has not been filed, but will be filed prior to applying for an EPA NOI SWPP. Prior to construction the project will pursue a building permit, and driveway permit. The project will also submit a demolition permit to remove the existing house prior to completing the project. + Replacement Tree plan for the replacement of any significant trees on site displaced by construction. (min 1” caliper) and/or payment to the city for any difference thereof See Sheet LC 121 and LC 122 for Northampton Significant Trees within or adjacent to the proposed work area (trees greater than 20” caliper, not indicated as diseased). Please note that there are 5 trees deemed “Significant trees” scheduled for removal. See Sheet LC131 and LC 132 for proposed planting tree location, species, and size. All proposed trees meet Northampton’s requirement. 350‐12.3 (d) Replacement trees shall either be approved street tree species as defined in the rules and regulations regarding subdivision of land or other trees that are hardy in all of the following USDA Plant Hardiness Zones: 6a, 6b, 7a, and 7b. If the full caliper replacement trees are not reached by the replacement planting onsite, the owner will pay the difference according to: 350‐12.3 E. (2) Pay funds to the City for a tree replacement fund account that, in the Planning Board's estimate, will allow the City to plant new public shade trees on City property in accordance with the above formula. + Maintenance schedule for plantings for the first two years. Trees to be planted as shown on the plans will be cared for by the owner or the owner’s consultant. Trees will be watered prior to planting, and at the time of planting, weekly for each tree. The owner or the owner’s consultant may use gator bags at the base of each newly planted tree, or install temporary irrigation on a timer to ensure the consistent watering of trees. Shortly after planting, Berkshire Design will review the planted trees to look for stress, cracks, other damage to the trees. After the first winter, Berkshire Design or the client’s designated consultant will review the trees on site to confirm tree health and vitality. At the end of the 24‐month period after installation, the Owner or the Owner’s consultant will coordinate with the City review of the replacement trees for completion of tree replacement requirements. + Written Description of how the project demonstrates (goes into online form, numbers need to be retained for ease of reference. 1. Will protect adjoining premises from seriously detrimental uses. The proposed work at 176 Turkey Hill, redevelops a previously developed 1.8 acre portion of a 40.3 acre property. There is no change to the proposed use from existing. The proposed development exceeds all dimensional setbacks and open space requirements. Stormwater is being managed with no increase in runoff within a 100‐year event. 2. Will promote safety of vehicular and pedestrian movements, minimize and mitigate traffic impacts. The proposed work at 176 Turkey Hill does not change or alter the pedestrian nor the vehicular circulation patterns at Turkey Hill Road. It does not increase the amount of Traffic at Turkey Hill Road as the proposed use, a single‐family home matches that of the existing use. The project has simulated the turning movements of Northampton’s safety vehicles and accommodates sufficient access and turn‐around within the site. 3. Promote a harmonious relationship of structures and open space. The proposed house is placed at a level plateau within the 40.3‐acre site and set back from the driveway to frame views of the adjacent wetlands and woods. The house proposes exterior pedestrian connections at both the front and back to facilitate connection with the surrounding terrain. The majority of the site is left as is, wooded with several old logging roads and trails. 4. Bears positive relationship to public convenience or welfare. The project maintains a significant portion of the parcel as open space, which in turns acts as a carbon sink, helps absorb stormwater and provides valued habitat. By redeveloping the existing developed plateau, the project minimizes environmental impacts, and does more than a typical building lot within its zone to provide public benefits associated with carbon sequestration and habitat for wildlife. 5. Avoid overloading and mitigate impacts on City resources and infrastructure. The project will rely on site septic and site water supply sources, not using the city’s municipal water supply nor relying on the City’s sewage treatment plant to process stormwater. The project will include a fire suppression system with onsite fire suppression water tanks in either the basement or below grade within the exterior site. Additionally, the project will be improving the existing stormwater runoff by collecting all the stormwater falling on the roof on the house and garage and putting that into subsurface systems which can process up to the 100 year storm. The existing site does not retain, store, or treat the existing stormwater falling upon the existing house. 6. Promote city planning objectives and will not adversely effect those objectives as defined in the City Master and study plans (meet all zoning requirements) Reviewing the Sustainable Northampton Comprehensive Plan, January 2008, “ The comprehensive plan is designed to provide a basis for decision‐making regarding the long‐term physical development of the municipality and requires Planning Board approval. Likewise, one purpose of the Zoning Act (Massachusetts General Law Chapter 40A) and zoning adopted by communities is to encourage the most appropriate use of land, including consideration of the recommendations in the comprehensive plan.” Significantly improve energy efficiency in city buildings and programs, reduce greenhouse gas emissions, and encourage conservation and use of alternative and renewable energy sources throughout the community: The project’s house is oriented to take advantage of future solar panels applied to the southern face of the building’s roof. Recognize and foster the unique history, character and function of each residential, commercial, mixed use, and open space neighborhood. The project proposes context sensitive development and open space residential development compatible with conservation purposes. The developed area is limited to the 1.8 acre portion of the property which is previously developed/ disturbed of the entire 40.3 acre parcel. Turkey Hill Road is a heavily wooded neighborhood and the proposed work maintains that character and places the house far away from the frontage keeping in character with the neighborhood. 7. Meets special regulations set forth in the Zoning chapter The project meets existing conditions and/or complies with the zoning regulations applied to the SC and RR Zones. ***** Site plan Criteria Address how you meet ALL THREE of the criteria below to improve circulation and reduce traffic and parking and any other related mitigation: 1. Minimizing curb cuts, using only ONE unless traffic safety requires more, and using access from a common driveway, shared service road, or existing side street when possible. The proposed scope does not increase the number of curb cuts into the property. Access into the property is through a single 10’ wide driveway. 2. Separation on‐site of pedestrians, bicycles, and vehicles. This is a Rural Residential / SC Zone project along a wooded road with rolling terrain. Frontage of the project area is within the Riverfront Area and as such the project seeks to preserve as much of the existing wood and vegetation along its frontage. Within the interior of the site, a sidewalk connecting the front door to the driveway is provided and pedestrian connections over softscape are provided around the house and allow for access to on site trails. 3. Reducing parking demand and reducing the number of required parking spaces (provide detail on any request to reduce the number of parking spaces). There is no change to the number of parking spaces on site. This project is a residential project and accommodates all parking within the parcel’s interior. Site Plan ‐ Onsite Traffic Describe in detail how your project will avoid traffic conflicts where traffic accesses your site, including any traffic mitigation at your curb cut: The driveway has been shifted in its footprint 3.5 feet to the east. This will help improve sight lines for vehicles exiting the residential property. Within the property the driveway widens and provides stable surfaces for emergency vehicles to turn around. Site Plan ‐ Offsite Traffic Describe in detail how your project mitigates all off‐site (beyond your driveway access point) traffic impacts using one of the following three approaches: 1. Providing off‐site traffic improvements or public bicycle and pedestrian improvements that reduce traffic to mitigate for your projects traffic. We believe this is not applicable as there is no anticipated increase in traffic. The existing parcel has a single family home and the proposed scope rebuilds a more energy efficient single family home. 2. Paying payment‐in‐lieu of traffic, bicycle, and pedestrian improvements in accordance with the Zoning. We believe this is not applicable as there is no anticipated increase in traffic. 3. Providing clear documentation as to why your project does not generate any new traffic. The existing parcel has a single family home and the proposed scope demos the existing house and builds one new single family home. There is no change in use and thus no change in anticipated traffic to and from the parcel. Site Plan ‐ Request Waivers List any requested waivers from the requirements that the plans include the following, along with the reasons for those waivers: 1. Site plan at 1"=40' or greater. No waiver requested. Site plans at 1”=20’‐0” 2. Name and address of the owner and developer, name of project, and date. No waiver requested. 3. Existing and proposed buildings, property line setbacks, building elevations, exterior entrances/exits. The existing building will be demoed with the project. Proposed building elevations and plans are provided with the submission. Property line setbacks are included on the plans. 4. Present and proposed use of the land and buildings. No waiver requested. 5. Existing and proposed topography using two foot contours. No waiver requested. Site survey has been prepared by a Professional Land Surveyor with 1’ contours. 6. Wetlands, streams, water bodies, drainage swales, wetlands, unique land features. No waiver requested. Site survey has been prepared by a Professional Land Surveyor with delineations as delineated by a professional wetland scientist. 7. Location of parking, loading, public/private ways, driveways, walkways, access and egress, surfacing. No waiver requested. 8. Location and details of all storm water drainage, detention and water quality facilities, public and private utilities and easements, sewage disposal facilities, water supply facilities. Location of all stormwater drainage and water quality facilities are provided as well as details. Electric service is shown and location of future water supply well and septic system are shown on the plans. More details will be provided for well and septic design by the well and septic engineers at the time of applying for septic and well permits with the City’s Board of Health. 9. Existing and proposed landscaping, trees, plantings, stone walls, buffers, and fencing. No waiver requested. 10. Existing and proposed sign locations, dimensions and details. No waiver requested. No existing signs on site. 11. Provisions for refuse removal and screening. No waiver requested. This is a single‐family home. Client will keep trash receptacles in the garage. House and garage are over 500’ away from the road and view of the garage is blocked from Turkey Hill Road by the terrain. 12. Lighting/photometric plan (with a maximum of 0.5 foot candles at property boundary). No site lighting is proposed at this time. If downlights are proposed on the building they will be full cut off and dark sky compliant. 13. Erosion control plan (MAJOR projects only). No waiver requested. Erosion Control Plan provided with the permit drawing set. 14. Traffic study (MAJOR projects only). Waiver requested. We believe this is not applicable as the parcel has an existing single‐family home which will be demoed and replaced with a single‐family home, resulting in no net change in traffic. 15. Stormwater Management Plan with Drainage Calculations (MAJOR projects only). Since the area of disturbance is greater than 1 acre, we have prepared a stormwater management plan and report with drainage calculations. 16. Plans stamped by Professional Engineer (MAJOR projects only). No waiver requested. Hard copies are stamped. Digital copies are unstamped. 1 Rachel Loeffler From:adelisle=northamptonma.gov@mg.unibank.net on behalf of adelisle@northamptonma.gov Sent:Thursday, February 25, 2021 12:20 PM To:Rachel Loeffler Subject:Planning Permits - Your payment has been confirmed!

Page 2 I. Introduction The following report presents an analysis of the stormwater runoff and stormwater management for the construction of a new 4,448± s.f. two-story residence, a 1,437± s.f. garage, a 560’ paved driveway, paved parking and sidewalks. The site is located at 176 Turkey Hill Road. The site is not located within a flood plain as per the most recent FEMA information. (See Appendix D) The site also does not contain any areas located within the NHESP Estimated Habitats of Rare Wildlife or Priority Habitats of Rare Species. (See Appendix E) II. Site Terrain and Soils The existing 40.3 acre site contains an existing single family house with three sheds. The house, sheds and drive are concentrated at the lower, northeast corner of the parcel. An existing 515’ gravel driveway leads up at approximately 12.5% to 16% grades to the house from Turkey Hill Road. The northwestern portion of the parcel slopes steeply down toward Turkey Hill Road, the eastern part of the parcel slopes steeply down toward the eastern abutter and the southern portion of the parcel slopes steeply down toward the wetlands. A soil evaluation was done by Berkshire Design on November 4, 2020 and is included in Appendix B. Eight test pits were excavated as shown on the test pit location plan. The Natural Resources Conservation Service Web Soil Survey for Hampshire County, Massachusetts classifies the site soils as: 253C – Hinckley loamy sand, 8 to 15 percent slopes The profile from the Web Soil Survey lists these soils as loamy sand. All of the test pits fall within this soil type and all but Test Pit #8 have receiving layers of variants of sand. Test Pit #8 has a receiving layer of sandy loam. From the Rawls Rates table in the MassDOT Stormwater Handbook, the infiltration rate for Sand is 8.27 inches/hour and for Sandy Loam is 1.02 inches/hour, which are used in the calculations. (see Appendix B for the soil report): Per the Web Soil Survey Legend, the Hinckley soils are listed as Hydrologic Soil Group “A”. See Appendix B. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc. Page 3 306D – Paxton fine sandy loam, 8 to 15 percent slopes, very stony The profile from the Web Soil Survey lists these soils as fine sandy loam. Per the Web Soil Survey Legend, the Paxton soils are listed as Hydrologic Soil Group “C”. See Appendix B. 311C – Woodbridge fine sandy loam, 8 to 15 percent slopes, very stony The profile from the Web Soil Survey lists these soils as fine sandy loam. Per the Web Soil Survey Legend, the Woodbridge soils are listed as Hydrologic Soil Group “C/D”. See Appendix B. III. Existing Conditions As noted above, the site is an existing single family house with three sheds. There is an existing 515’ gravel driveway, a gravel parking area and landscaping. The existing conditions have been analyzed as four drainage areas containing a total area of 448,670 s.f. The area analyzed contains the areas affected by the development and the upslope areas contributing to the area of development. The existing drainage area boundaries are depicted on the Pre-Development Drainage Area Plan (Figure 1). The following is a brief description of the drainage areas: Area E1A Area E1A is approximately 97,119 square feet (s.f.) in size and contains the existing house, most of the gravel driveway, the riprap driveway swale, wooded areas and grass areas. This area drains northerly toward Turkey Hill Road, which is control point (CP-E1). Area E1B Area E1B is approximately 180,597 square feet (s.f.) in size and contains the wooded areas up the slope of a steep hill, a former driveway, walking paths and grass areas. This area drains northerly toward a culvert under the existing gravel driveway, then down the driveway drainage swale and then on to Turkey Hill Road, which is control point (CP-E1). Area E2 Area E2 is approximately 76,631 s.f in size and contains the eastern portion of the area of disturbance. This area contains two sheds, a walking path, woods and grass areas. This area drains easterly toward the eastern abutter, which is control point (CP-E2). Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc. Page 4 Area E3 Area E3 is approximately 94,323 s.f in size and contains the southern portion of the area of disturbance. This area contains a shed, a gravel parking area, woods and grass areas. This area drains southerly toward the wetlands, which is control point (CP-E3). IV. Proposed Conditions The proposed development will be a mixture of new development and redevelopment. The new development includes the construction of a new 4,448± s.f. two-story residence, a 1,437± s.f. garage, paved parking, lawn and landscaping areas and sidewalks. The redevelopment portion will include a 560’ paved driveway, a stormwater stilling basin and a bio-retention area. New electric utility services will be connected to the building from the existing electric utilities in the area. A new on-site sewage disposal system will be constructed to service the new house. A new potable water supply well will be drilled to the south of the proposed house at a distance greater than 100’ from the proposed septic system. A new surface detention/infiltration basin and a subsurface infiltration system will be constructed to mitigate the stormwater peak runoff in the pre- vs. post- development conditions. Two new bio retention areas will be constructed to provide water quality treatment. The proposed conditions will be analyzed with twelve drainage areas with a total area of 448,711 s.f. The proposed drainage area boundaries are depicted on the Post-Development Drainage Area Plan (Figure 2). The following is a brief description of the drainage areas: Area P1A Area P1A is approximately 15,579 s.f. in size and is the northeastern portion of the analysis area containing a portion of the paved driveway, grass and woods. Runoff drains overland northerly toward Turkey Hill Road, control point (CP-P1). Area P1B Area P1B is approximately 7,616 s.f. in size and contains a portion of the paved driveway, grass and woods. Runoff drains overland northerly toward the driveway at Turkey Hill Road, control point (CP-P1). Area P1C Area P1C is approximately 57,230 s.f. in size containing a portion of the paved driveway and riprap driveway swale, grass and woods. Stormwater runoff from this area drains to bio retention area #1 (BR1) which discharges over the stone or log lined spillway and sheet flows to Turkey Hill Road, control point (CP-P1). Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc.

Page 6 Area P2C Area P2C is approximately 5,245 s.f in size and contains the roof area of the new house and garage. This area drains to subsurface infiltration system (SIS) which overflows to the grass lined level spreader (LS1) and then sheet flows to the eastern abutter, which is control point (CP-P2). Area P3 Area P3 is approximately 86,021 s.f in size and contains the southern portion of the site. This area contains woods and grass areas. This area drains southerly toward the wetlands, which is control point (CP-P3). V. Calculations and Design Drainage calculations were performed on HydroCAD Stormwater Modeling System (HydroCAD) version 10.0 using Natural Resources Conservation Service (NRCS) TR-20 methodology. The NRCS 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 NRCS distribution provides a cumulative rainfall at any point in time and allows volume dependent routing runoff calculations to occur. These calculations are included in the appendices. The watershed boundaries for calculation purposes are divided according to the proposed site grading and the natural limits of the drainage areas. The curve numbers (CNs) and times of concentration for the existing and proposed subcatchment areas are based on the soil type and the existing and proposed cover conditions at the site. Watershed subcatchment areas, runoff coefficients and watercourse slopes are based on survey information. In the HydroCAD report in Appendix A, certain nodes are listed as “Ponds”. A “Pond” is defined in HydroCAD as a node used to model the storage effects of any retention or detention area, such as a reservoir, detention pond or storage chamber. All such “Ponds” used in this project are designed to either exfiltrate or drain the stormwater completely. There will be no “Ponds” associated with this project which will contain standing water. Calculations were performed for the 1-, 2-, 10-, and 100-year frequency storms under existing and proposed conditions. The results of the calculations are presented in Table 1 below. Appendix A presents the HydroCAD calculations. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc.

Stormwater Standards Compliance The following section details how the project will meet DEP Stormwater Management Policy requirements: Standard 1 - Untreated Stormwater Bio retention area BMP’s are proposed for this project. Stormwater runoff from all of the new bituminous pavement will be routed to one of these two BMP’s prior to discharge over the spillway from bio retention area #1 (BR1). The subsurface infiltration system (SIS) will receive runoff from the house and garage roofs only. No Erosion to Wetlands: A. Runoff to the wetlands from the proposed work will sheet flow through grass and woods at least 50’ at all locations: no erosion to wetlands. B. Runoff to the eastern abutter from the grass lined level spreader (LS1) will sheet flow through 65’ of woods prior to the eastern property line. B. Exhibit 8-24 of the MassHighway Project Development & Design Guide, 2006 Edition, lists permissible velocities for channels lined with grass. HydroCAD was used to analyze the discharge velocities from overflow spillway in bioretention area #1. (See Appendix A) Exhibit 8-24 lists the maximum permissible velocity for channels lined with grass as 2.5 fps. Table 2 below lists the calculated velocities at the overflow spillway: Point of Analysis 2yr Discharge Velocity (fps) 10yr Discharge Velocity (fps) 100yr Discharge Velocity (fps) Overflow Spillway 0.35 0.93 1.32 Table 2 – Discharge Velocities Standard 2 - Post-Development Peak Discharge Rates and Runoff Volume See Table 1 and the Summary above. Standard 3 - Recharge Required Recharge Volume: Rv = F x Impervious Area Existing driveway and roof area = 11,621 s.f. Proposed driveway and roof area = 15,593 s.f. Increase in Impervious Area = 3,972 s.f. Per MADEP Stormwater Handbook, F = 0.6in for HSG A soils. Rv = (0.6in)(1ft/12in)(3,972 s.f.) = 200 c.f. The recharge volume available in detention/infiltration basin #3 up to the overflow weir is approx. 1,000 c.f. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc. Page 9 Standard 4 – Water Quality Water Quality Treatment Volume: VWQ = (DWQ/12in./ft.) x AIMP DWQ (Water Quality Depth): Infiltration Rate > 2.4 in./hr., use 1” For Bio retention area #1: AIMP = 4,738 s.f. VWQ = (1in./ 12in./ft.)(4,738 s.f.) = 395 c.f. For Bio retention area #2: AIMP = 4,600 s.f. VWQ = (1in./ 12in./ft.)(4,600 s.f.) = 385 c.f. Per the HydroCAD calculations, the volume in the surface of Bio retention area #1 is 775 c.f. The volume in the surface of Bio retention area #2 is 620 c.f. TSS Removal: TSS removal calculations are included in Appendix F. The Bio retention area #1 treatment train will remove 90% of TSS. The Bio retention area #2 treatment train will remove 90% of TSS. Standard 5 - Higher Potential Pollutant Loads The proposed site is not classified as a land use with higher pollutant loads. Standard 6 - Protection of Critical Areas The project site does not discharge to critical areas as defined in MA DEP Stormwater Policy Handbook. Standard 7 - Redevelopment Projects The project will be a mixture of New Development and Redevelopment. The New Development will be in the Subcatchment Areas P1F, P1G, P2A, P2B, P2C and P3 on the Post-Development Drainage Area Plan (DA-P). [See Figure 2]. The pre-development impervious area toward Turkey Hill Road will be 6,561 s.f. as taken from Subcatchment Area E1A on the Pre-Development Drainage Area Plan (DA-E). [See Figure 1]. The post-development impervious area toward Turkey Hill Road will be 4,727 s.f. as taken from Subcatchment Areas P1A through P1E on the DA-P plan. Therefore, the new development portion of the project will meet all of the Standards as set forth in the MADEP Stormwater Handbook. Standard 8 - Erosion/Sediment Control Erosion and sediment controls have been incorporated into the project design plans to (1) prevent erosion, (2) control sediments, and (3) stabilize exposed soils during construction and land disturbance. The contractor is required to complete a SWPPP prior to beginning construction in order to ensure that all erosion and sediment control measures are adequately implemented. (See Figures 5A & 5B) Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc. Page 10 Standard 9 - Operation/Maintenance Plan An Operation and Maintenance Plan for the proposed project is included in Appendix C. It includes general controls for construction and long term maintenance of the stormwater management system. Standard 10 – Prohibition of Illicit Discharges Standard 10 of the Massachusetts Stormwater Handbook prohibits illicit discharges to stormwater management systems. As stated in the handbook, “The stormwater management system is for conveying, treating, and infiltrating stormwater on-site, including stormwater best management practices and any pipes intended to transport stormwater to the groundwater, a surface water, or municipal separate storm sewer system. Illicit discharges to the stormwater management system are discharges that are not entirely comprised of stormwater.” Standard 10 also states that “The Illicit Discharge Compliance Statement must be accompanied by a site map that is drawn to scale and that identifies the location of any systems for conveying stormwater on the site and shows that these systems do not allow the entry of any illicit discharges into the stormwater management system. The site map shall identify the location of any systems for conveying wastewater and/or groundwater on the site and show that there are no connections between the stormwater and wastewater management systems and the location of any measures taken to prevent the entry of illicit discharges into the stormwater management system.” The site plans included with the Site Plan application and the Request for Determination of Applicability application displays the location of all of the stormwater management components on the project site and conforms to requirements of a “site map” to accompany the Illicit Discharge Compliance Statement. The Illicit Discharge Compliance Statement for the 176 Turkey Hill Road project is as follows: Illicit Discharge Compliance Statement Per the requirements of Standard 10 of the Massachusetts Stormwater Management Standards it shall be stated there will be No Illicit Discharges under the scope of this project, the 176 Turkey Hill Road Project.

HSG Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 11/3/2020 Page 3 of 4 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.

Appendix C – Proposed Stormwater Management System Operation & Maintenance Plan Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report 1 Proposed Operation & Maintenance Plan Stormwater Management During Construction The Contractor shall be responsible for inspection and maintenance during construction. At all times, siltation fabric fencing, stakes and hay bales sufficient to construct a sedimentation control barrier a minimum of 50 feet long will be stockpiled on the site in order to repair established barriers which may have been 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 all or one of the following: · Any storm in which rain is predicted to last for twelve consecutive hours or more. · Any storm for which a flash flood watch or warning is issued. · Any single storm predicted to have a cumulative rainfall of greater than 1/2 inch. · Any 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 significant. 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 Conservation Commission shall be notified of any significant failure of stormwater management systems & 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 face 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 Constriction 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. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report 2 Post-Construction Stormwater Management System Owner: Linda Doucette-Ashman and Harvey Ashman 176 Turkey Hill Road Northampton, MA 01062 ldoucette31@gmail.com harvey.ashman@gmail.com Party Responsible for Operation & Maintenance: Linda Doucette-Ashman and Harvey Ashman 176 Turkey Hill Road Northampton, MA 01062 ldoucette31@gmail.com harvey.ashman@gmail.com Inspection & Maintenance Schedule: 1) Detention Basins (The following recommendations follow the MADEP Stormwater Policy guidelines.) Inspections a. Initial six months of use: Inspect infiltration basins after every major storm event. Examine for stabilization and function, including determination of the duration of water standing in the basin, any sediment erosion, excessive compaction of soils, or low spots. b. Twice per year: Examine basin for the following: differential settlement, cracking, erosion, leakage, condition of riprap, sediment accumulation, and health of turf. Any adverse conditions noted during any inspections shall be addressed by repair or reconsideration of design components. Weeding and General Maintenance Occasional weeding (1-2 times per year min.) shall be performed on the side slopes and basin bottom. Accumulated grass clippings and/or organic matter and trash and debris shall be removed. Any clogged surface areas can be loosened by deep tilling; tilled areas must be immediately re-vegetated. Tilling may be used in this manner for no more than two consecutive maintenance periods. Thereafter, sediment in the clogged areas shall be removed, liner material replaced, and vegetation re-established. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report 3 Dredging/Sediment Removal Accumulated sediment shall be removed from the basin at five (5) year intervals, or as required to maintain the function of the stormwater management system as designed. During this process and until the disturbed sediment has settled, the outlet pipe shall be sealed so as to minimize the risk of conveying sediment beyond the basin. 2) Grass Level Lip Spreader The level lip spreader shall be inspected annually for sediment buildup and evidence of bypassing. It shall be cleaned by removing any sediment. After sediment is removed, the grass shall be replanted. Sediments shall be removed and disposed of in accordance with local, state and federal guidelines and regulations. Inspections shall identify any damage or signs of erosion within and adjacent to the level lip spreader, which shall be repaired immediately. It is recommended that sediment removal, if any, be performed after the completion of the spring snow melt. 3) Subsurface infiltration System A subsurface infiltration system, constructed from 3 ft. diameter perforated HDPE pipes and crushed stone, is designed to temporarily store excess runoff prior to infiltration and/or discharge. Proper maintenance of roof gutters and these structures will protect the integrity of the subsurface infiltration system. The subsurface infiltration system shall be inspected as noted below, and if any sediment is observed in the chambers, the owner should contact a professional engineer to evaluate the impact, recommend changes to the pre− treatment devices or maintenance procedures, and to determine if remedial action is necessary. If sediment is allowed to build up, it may be necessary to excavate and clean the pipes. Inspection / Maintenance Frequency The subsurface infiltration system must be cleaned and maintained. Underground systems may be maintained more cost effectively if these simple guidelines are followed. Inspection should be performed at a minimum of once per year. Cleaning should be done at the discretion of individuals responsible to maintain proper storage and flow. While maintenance can generally be performed year round, it should be scheduled during a relatively dry season. Pre-Inspection A post-installation inspection should be performed to allow the owner to measure the invert prior to accumulation of sediment. This survey will allow the monitoring of sediment build-up without requiring access to the subsurface infiltration system. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report 4 The following is the recommended procedure for pre-inspections: 1) Locate the cover of the drain manhole connected to the subsurface infiltration system. The riser will typically be 24” in diameter or larger. 2) Remove the cover. 3) Insert a measuring device into the opening and make note to a point of reference on the stick or string. (This is done so that sediment build up can be determined in the future without having to enter the system.) Inspection / Maintenance The subsurface infiltration system should be inspected at a minimum of one time a year or after major rain events if necessary. The following is the recommended procedure to inspect system in service: 1) Locate the cover of the drain manhole connected to the subsurface infiltration system. The riser will typically be 24” in diameter or larger. 2) Remove the cover. 3) Observe for standing water if longer than 8 hours past the last major storm event. If water is observed, the owner should contact a professional engineer to evaluate the impact. 4) Measure the sediment buildup at each riser and cleanout location. Only certified confined space entry personnel having appropriate equipment should be permitted to enter the subsurface infiltration system. 5) Inspect each manifold, all laterals and outlet pipes for sediment build-up, obstructions or other problems. Obstructions should be removed immediately. 6) If measured sediment build-up is between 3” and 4”, cleaning should be considered. If sediment build-up exceeds 4”, cleaning should be performed at the earliest opportunity. A thorough cleaning of the system shall be performed by either manual methods or by a vacuum truck. 4) Bio Retention Areas The bio retention areas shall be inspected at least four times per year for sediment accumulation and signs of damage or erosion. Sediment shall be removed any time it has accumulated more than 1”. Sediment shall be removed annually, preferably during spring cleanup. At that time, sediment and the previous year’s mulch shall be removed and new mulch installed. Failure of the system to drain (ponding 48 hours after the end of the storm) shall result in inspection and cleaning. Sediments shall be removed and disposed of in accordance with local, state and federal guidelines and regulations. It is recommended that sediment removal be performed after the completion of the spring snow melt. Inspections shall identify any damage or signs of erosion within basins or the overflow berm. Damage shall be repaired immediately. Single Family Residence February 22, 2021 176 Turkey Hill Road, Northampton, Massachusetts Stormwater Drainage Report The Berkshire Design Group, Inc.

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 must be submitted with the Stormwater Report. 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. 176 Turkey Hill Road Stormwater Checklist • 04/01/08 Stormwater Report Checklist • Page 2 of 8 Massachusetts Department of Environmental Protection Bureau of Resource Protection - Wetlands Program Checklist for Stormwater Report B. Stormwater Checklist and Certification The following checklist is intended to serve as a guide for applicants as to the elements that ordinarily need to be addressed in a complete Stormwater Report. The checklist is also intended to provide conservation commissions and other reviewing authorities with a summary of the components necessary for a comprehensive Stormwater Report that addresses the ten Stormwater Standards. Note: Because stormwater requirements vary from project to project, it is possible that a complete Stormwater Report may not include information on some of the subjects specified in the Checklist. If it is determined that a specific item does not apply to the project under review, please note that the item is not applicable (N.A.) and provide the reasons for that determination. A complete checklist must include the Certification set forth below signed by the Registered Professional Engineer who prepared the Stormwater Report. Registered Professional Engineer’s Certification I have reviewed the Stormwater Report, including the soil evaluation, computations, Long-term Pollution Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long- term Post-Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement (if included) and the plans showing the stormwater management system, and have determined that they have been prepared in accordance with the requirements of the Stormwater Management Standards as further elaborated by the Massachusetts Stormwater Handbook. I have also determined that the information presented in the Stormwater Checklist is accurate and that the information presented in the Stormwater Report accurately reflects conditions at the site as of the date of this permit application.

All wetlands in this area that may be protectable under the Massachusetts Wetlands Protection Act (M.G.L. chapter 131, section 40) and Regulations (310 CMR 10.00), as well as the Northampton Wetlands Protection Ordinance, have been marked in the field with consecutively numbered pink “wetland delineation” flagging tape or stake-flags. While these boundaries have been accurately identified, only the Northampton Conservation Commission, or the Massachusetts Department of Environmental Protection (DEP) on appeal under State law, can make the final determination of the extent of the wetland resource areas on the site. Delineation Methodology The methodology employed in my delineation utilized both vegetation and hydrology as outlined in the Regulations at 310 CMR 10.55 and in the DEP handbook Delineating Bordering Vegetated Wetlands under the Massachusetts Wetlands Protection Act (1995). Hydrophytic Vegetation was based upon the US Fish and Wildlife Service’s National List of Plant Species that Occur in Wetlands (1988), as well as all plant species listed in the Act. Wetland hydrology includes a high water table, water-stained leaves, and hydric soils. Hydric soils were determined based upon the interagency document Field Indicators for Identifying Hydric Soils in New England, Version 4 (2016). Site Description The area subject to my investigation is located at 176 Turkey Hill Road, and contains an existing single family home, out building, lawn, and driveway. To the west of the developed site, a braided intermittent stream (dry at the time of my site visits) flows down the rocky hillside, splits into two channels, and then combines again at the edge of the existing lawn before leaving the site to the southeast. Flags A-1 to A-70 and B-1 to B-60 mark the braided stream channels; D-1 to D-30 encircle an upland “island” between the streams. Flags C-1 to C-11 mark a wetland to the south of where the intermittent stream exits the vicinity of the lawn. This area is fed by groundwater discharge from the base of the hillside. There are other wetlands on the site that are not shown on the accompanying survey because 2 they are located outside of the project area. A perennial stream is located on the opposite side of Turkey Hill Road. Flags 2HW-1 to 2HW 10 and HW-1 to HW-36 mark the Mean Annual High Water Line (MAHWL) of this brook. The MAHWL was coincident with the top of the “bank” in this area. There is also a wetland fringe along the brook; flags F-1 to F-5, 2F-1 to 2F-16, and G-1 to G-10 mark this wetland. Wetland Resource Areas Under the state Regulations (310 CMR 10.00), wetlands are broken up into different resource areas, each of which is regulated in a slightly different manner. The delineated wetlands contain the following resource areas, to which there is a 100 foot buffer zone. * Bank (10.54) * Bordering Vegetated Wetland (10.55) * Land Under a Waterway (10.56) According to the most recent USGS Quadrangle, the stream on the opposite side of Turkey Hill Road is shown as a dark blue, perennial waterway. Therefore, the following resource area extends for 200 feet from the delineated Mean Annual High Water Line of the stream: * Riverfront Area (10.58) Project Planning It is my understanding that the current proposed project is to remove the existing single family home and to replace it with a new home, along with the repair and upgrade of the existing driveway. Given that the lower portion of the driveway is within the Riverfront Area, a Notice of Intent (WPA form 3) will need to be filed with the Northampton Conservation Commission. Northampton also has various setbacks from the wetland boundary that are required for buffer zone projects under the Northampton Wetlands Protection Ordinance. The site does not fall within the Estimated Habitats of Rare Wildlife or Priority Habitats of Rare Species according to the most recent online mapping. Therefore, unless new information becomes available, you should not have to make any filing with the Natural Heritage and Endangered Species Program. Please feel free to contact me if you have any questions regarding the delineation.

Assignment On August 26, 2020, Donald Teagano of Teagano Construction Incorporated (TCI), contracted my services to assist with his client's construction project at #176 Turkey Hill Road in Northampton, Massachusetts. The proposed construction project will interact with some of the trees on the property. At the owner's request I was contracted to inventory selected trees on the property before the start of the project. A. Scope of Work The scope includes inventorying and assessing the selecting existing trees on the property at #176 Turkey Hill Road in Northampton, Massachusetts. All of the selected trees were given a tree identification number. The following information was collected for each tree. Identify the existing trees in the defined survey limits of the property with a dbh (trunk diameter at 4.5 feet above the ground) of 20" or greater. Identify trees that are less than 20" dbh if they are considered a specimen tree by the arborist. Each inventoried tree will receive a basic tree risk assessment. Selected inventoried tree will receive recommendations of tree protection. The critical root zone (CRZ) will be determined for each selected tree. Recommendations of tree care will be recommended for selected trees such as pruning, removal or pest management. At the completion of the tree risk assessment and tree protection report I will discuss a plan on site with the Harvey Ashman, Linda Doucette-Ashman and representatives of Teagano Construction to implement the recommendations of the report. Tree Risk Assessment and Tree Protection 3 176 Turkey Hill Road, Northampton, Massachusetts 9/14/2020 McCarthy, Charles W. - Consulting Arborist ISA Certified Arborist The main objectives are to identify risk trees, significant trees and trees that offer an aesthetic contribution to the property. Donald Teagano supplied me with a drawing of the proposed construction project for #176 Turkey Hill Road. In Northampton, Massachusetts. He requested that I plot the inventoried trees on a supplies drawing and to identify the trees that require tree protection measures. II. Observations and Tree Risk – Site visits on 9/1/2020 , 9/7/2020 and 9/11/2020 All of the selected trees were affixed with a tree identification number tag which will be referred to throughout the project. A tree identification number was affixed to every inventoried tree.

Consulting Arborist ISA Certified Arborist III. Analysis Prior to the preparation of this report I inventoried the existing trees with a dbh of 20" or greater in the designated area defined in the tree location drawing #1 (page #4). I identified trees less than 20" that I consider specimen trees or trees that may contribute to the woodland landscape. I performed a basic tree risk assessment on every inventoried tree. Mitigation recommendations and tree protection determinations were made for each tree.. A. Pre-existing Tree Health Issues and Mitigation Many of the trees that were inventoried and inspected were trees along the perimeters of the driveway. Some of the trees inventoried were dead or nearly dead before my inspections. Other trees that were inspected had defects that pre-dispose them to failure. These trees recommended for removal can be found in table #2. Many trees that were inventoried had some lower deadwood in their crown. This is normal and related to shading. Other trees had branches that threatening the incoming service wires. Trees recommended for pruning can be found in table #3. Some trees should be considered for removal because they threaten other trees or they don't contribute to the landscape. Trees recommended to be considered for removal can be found in table #4. Some hemlocks had symptoms indicative of the hemlock woolly adelgid. Some birch trees had symptoms indicative of the bronze birch borer. Trees recommended for pest management can be found in table #5.

Conclusion This report attempts to address selected trees individually that may be involved with the construction project. Additions and exceptions will certainly have to be made as the project evolves. The report should be used as a guide to the contractors and to emphasize that the trees are important to the city of owners of the property. Hopefully it will assist the owners and its’ contractors to work as a team to protect the trees.
