Rocky Hill Trail CPA Application.pdfPage | 1 COMMUNITY PRESERVATION PROJECT APPLICATION COVER SHEET I: Project Information Project Title: Rocky Hill Greenway Multi-Use Trail Project Summary: $3.6 million in federal earmark funding specifically for multi-use trail construction in Northampton will soon be made available. We are requesting CPA funds to complete and update the final trail design from Route 10 to Route 66 through the Rocky Hill Greenway. Federal funding is available for construction work, but design costs for this portion of the projecy are ineligible. Estimated start date: 2022 Estimated completion date: 2024 CPA Program Area (check all that apply): � Open Space � Historic Preservation � Community Housing X Recreation II: Applicant/Developer Information Contact Person and or/primary applicant: Carolyn Misch Property Owner (if applicable): Northampton Conservation Commission Organization (if applicable): Office of Planning and Sustainability Mailing Address: City Hall, 210 Main Street, Northampton MA 01060 Daytime phone #: (413)587-1287 Fax #: (413)587-1264 E-mail address & Website: cmisch@northamptonma.gov Northamptonma.gov/plan III: Budget Summary Total budget for project: $3,600,000 CPA funding request: $60,000 CPA request as percentage of total budget: 1.7% Applicant’s Signature: Date Submitted: September 15, 2022 Page | 2 Narrative: Project location – Rocky Hill Greenway, Parcel ID 37-049, to connect Rocky Hill Road/Rt 66 with the New Haven-Northampton Canal Greenway just north of the Easthampton Road/Rt 10 crossing. The Rocky Hill Greenway Trail will be a 2,630 linear foot (0.50 mile) multi-use trail designed as a spur trail to connect two existing trails in the area. The area is located entirely within a City-owned parcel situated between Rocky Hill Road (MA Route 66) and Easthampton Road (MA Route 10). The proposed trail project will improve pedestrian and bicycle facilities by connecting the residential areas along Rocky Hill Road and Ice Pond Drive to the New Haven and Northampton Canal / Manhan Rail Trail. Bicyclists and pedestrians will benefit from being able to connect to these corridors more directly and with limited interaction with vehicular traffic, providing a safer and more direct route to the existing rail trail. Additionally, it will provide access to an eventual multi-use trail serving the southwestern and western half of the City, where the network is slowly expanding, but is largely not currently served by any multi-use trails. The proposed Rocky Hill Greenway Multi-Use Trail will support the City’s recreational goals by adding to the existing network of bike paths in the region and encouraging non- motorized travel, advancing the goals of the City of Northampton Open Space, Recreation, and Multi-Use Trail Plan (2018-2025). This Plan seeks (among other goals) to maintain vibrant urban centers, develop multi-use trails for easy public access, and create recreational opportunities while protecting valuable habitat and natural resources. The Open Space, Recreation & Multi-Use Trail Plan is an adoptive component of the Sustainable Northampton Comprehensive Plan (2008) and has been adopted or endorsed by a number of City Boards and approved by the Commonwealth of Massachusetts Executive Office of Energy and Environmental Affairs. By implementing this project, the City will progress toward three of the major goals outlined in the Massachusetts Department of Transportation (MassDOT) 2012 GreenDOT Implementation Plan, which include: • Design of multi-modal transportation system; • Promoting healthy transportation and livable communities; and • Tripling of the bicycle and pedestrian transportation modes. The project also supports the seven-corridor, 788-mile statewide system of bicycling routes, known as the Bay State Greenway. A pilot sign program in the Pioneer Valley is currently underway, linking a number of off-road paths and on-road routes in Massachusetts and connecting to systems in Connecticut and Vermont. Page | 3 The trail will be constructed of bituminous asphalt pavement and will vary in width between 10 and 16 feet to accommodate site conditions. At its northern end, off of Rocky Hill Road, the trail will following the existing gravel driveway and will be 16 feet wide; this portion of the trail will act as a shared multi-use trail and driveway, allowing restricted vehicle access to the existing gas pumping station. The trail will then narrow to ten feet in width at the wetland crossing, and will be limited to pedestrians and bicycles for the remaining length of the spur trail to the junction with the existing Manhan Rail Trail. Partially using CPA funding, the City engaged a consultant to complete trail design to the 25% level, and secure all necessary environmental permits. These documents helped to secure $3.6 million in federal funding for trail construction. CPA funds are now requested to engage an engineering consultant to finalize and update the plans to include design requirement changes, implemented since drafts were completed several years ago, and to review bids and oversee construction. A relatively small investment of City funds will be able to fully complete the trail to a ribbon cutting. The project meets many of the general review criteria for project evaluation: Serves more than one CPA program area While specifically a recreation project, the work will also enhance an open space area Contributes to the preservation of Northampton’s unique character, boosts the vitality of the community, and enhances the quality of life for its residents Northampton is well-known for its network of off-road multi-use trails. This trail, which will be open to hiking, walking, running, mountain biking, bicycling, cross country skiing, snow shoeing, roller blading, and dog walking, will tie into that network and provide additional meaningful opportunities for safe commuting and recreation options. Addresses recommendations contained in the Sustainable Northampton comprehensive plan and/or the Northampton Open Space, Recreation, and Mixed Use Trail Plan or is consistent with other city-wide planning efforts that have received broad-based scrutiny and input and can demonstrate wide community support Places high value on sustainable, ecologically responsible, energy-conserving structures, locations, and materials; demonstrates that the project minimizes the ecological footprint Receives endorsement by community groups, municipal boards and/or departments, and City residents. The project is presented by the Office of Planning and Sustainability, and is supported by the Massachusetts Audubon Society, who holds the restriction on the property, and Friends of Northampton Trails and Greenways Leverages additional public and/or private funds, or demonstrates that other funding sources are not readily available or sufficient Demonstrates a high benefit/cost value Can be implemented expeditiously and within budget Page | 4 The project also meets all of the recreational projects evaluation criteria: 1.

(HW) is pleased to submit this Notice of Intent for the proposed Rocky Hill Greenway Multi-Use Trail. The 2,630 linear foot trail is proposed to connect Rocky Hill Road (Route 66) to the New Haven and Northampton Canal/Manhan Rail Trail near Easthampton Road (Route 10), Northampton. A portion of the proposed project will occur within Bordering Vegetated Wetland and its associated buffer zone, as well as within Riverfront Area. None of this work is within the Natural Heritage and Endangered Species Program Estimated Habitat of Rare Wildlife and Certified Vernal Pools and Priority Habitat of Rare Species. These jurisdictional areas are protected and regulated under the Massachusetts Wetlands Protection Act (M.G.L. Ch. 131 § 40), its implementing Regulations (310 CMR 10.00) and the Northampton Wetlands Protection Ordinance (Chapter 337). Proposed mitigation includes providing wetland replacement at a greater than 1:1 ratio. Stormwater management practices will be implemented and an erosion and sedimentation control barrier will be used to protect downgradient resource areas. Construction-related impacts will be minimized and disturbed areas will be stabilized and restored upon completion of construction. HW has completed and submitted an online application, and is submitting nine copies of the NOI application, supporting documentation, and project plans directly to the Conservation Commission. One additional full size plan set is also included. A copy of the NOI has been filed with the Massachusetts Department of Environmental Protection (MassDEP), Western Regional Office. As the Applicant is a municipal entity, the project is exempt from filing fees. The Applicant will send notification of the pending public hearing to abutters in accordance with State and local filing regulations within the required timeframe. If you need additional information please contact us at (508) 833-6600. Thank you. Sincerely, HORSLEY WITTEN GROUP, INC. Amy M. Ball, PWS, CWS Senior Ecologist Justin L. Lamoureux, P.E.

Page 1 of 22 Rocky Hill Greenway Multi-Use Trail Northampton, Massachusetts Notice of Intent Project Narrative March 2019 SUMMARY The Applicant, the City of Northampton Planning & Sustainability, proposes a multi-use pedestrian and bicycle trail extending from Rocky Hill Road (MA Route 66) to Easthampton Road (MA Route 10) in Northampton, Massachusetts. This spur trail will serve to connect the New Haven and Northampton Canal/Manhan Rail Trail with the Rocky Hill Road neighborhood. The approximately 2,630-foot long project will be located entirely within property that has been deeded to the City of Northampton or is within easements provided by the Massachusetts Electric Company. A portion of the proposed bicycle and pedestrian trail will occur within Bordering Vegetated Wetland and its buffer zone, as well as a Riverfront Area, much of which has been disturbed. These resource areas are regulated under the Massachusetts Wetlands Protection Act and the City of Northampton Wetlands Ordinance (Chapter 337 of the Northampton Administrative Code) and associated regulations. Resource area impacts will be avoided and minimized to the extent practicable by using an existing dirt driveway and footpath, while still maintaining a trail that is safe and adheres to the local building code. An erosion and sedimentation control barrier will be used to further protect downgradient resource areas, and construction-related impacts will be minimized and restored upon completion of construction. Stormwater management practices will be implemented to the extent practicable for this project. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 2 of 22 1.0 INTRODUCTION The City of Northampton proposes the Rocky Hill Greenway Multi-Use Trail, a 2,630 linear foot (0.50 mile) multi-use trail designed as a spur trail to connect two existing trails in the vicinity. The proposed project is located entirely within a City-owned parcel situated between Rocky Hill Road (MA Route 66) and Easthampton Road (MA Route 10) in Northampton, Massachusetts. The proposed trail project will improve pedestrian and bicycle facilities by connecting the residential areas along Rocky Hill Road and Ice Pond Drive to the New Haven and Northampton Canal / Manhan Rail Trail. Bicyclists and pedestrians will benefit from being able to connect to these corridors more directly and with limited interaction with vehicular traffic, providing a safer and more direct route to the existing rail trail. Additionally, it will provide access to an eventual multi-use trail serving the southwestern and western half of the City, which is not currently served by any multi-use trails. 2.0 PROJECT BACKGROUND AND PURPOSE The proposed Rocky Hill Greenway Multi-Use Trail will support the City’s recreational goals by adding to the existing network of bike paths in the region and encouraging non-motorized travel, advancing the goals of the City of Northampton Open Space, Recreation, and Multi-Use Trail Plan (2018-2025). This Plan seeks (among other goals) to maintain vibrant urban centers, develop multi-use trails for easy public access, and create recreational opportunities while protecting valuable habitat and natural resources. The Open Space, Recreation & Multi-Use Trail Plan is an adoptive component of the Sustainable Northampton Comprehensive Plan (2008) and has been adopted or endorsed by a number of City Boards and approved by the Commonwealth of Massachusetts Executive Office of Energy and Environmental Affairs. By implementing this project, the City will progress toward three of the major goals outlined in the Massachusetts Department of Transportation (MassDOT) 2012 GreenDOT Implementation Plan, which include: Design of multi-modal transportation system; Promoting healthy transportation and livable communities; and Tripling of the bicycle and pedestrian transportation modes. The project also supports the seven-corridor, 788-mile statewide system of bicycling routes, known as the Bay State Greenway. A pilot sign program in the Pioneer Valley is currently underway, linking a number of off-road paths and on-road routes in Massachusetts and connecting to systems in Connecticut and Vermont. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 3 of 22 3.0 GENERAL SITE DESCRIPTION The proposed Rocky Hill Greenway Multi-Use Trail will be sited within a City-owned parcel (37- 049-001) located between Rocky Hill Road (MA Route 66) and Easthampton Road (MA Route 10) in Northampton, Massachusetts (Figures 1 and 2). The existing conditions at the site are varied. The northern portion of the proposed trail, starting at Rocky Hill Road, is currently occupied by a gravel driveway, which leads to a gas pumping station owned by the Tennessee Gas Transmission Company of Houston, Texas (Parcel 37-050-001). The proposed trail then passes through an easement of the Massachusetts Electric Company, which has overhead utility lines running through the maintained corridor. After crossing the easement, the southern portion of the proposed trail follows part of an existing footpath and then winds through undeveloped woodland area with grass, shrubs, and trees before connecting with the existing Manhan Rail Trail. 3.1 FEMA Designation According to the FEMA Flood Insurance Rate Map (Community Panel No. 250167 0002 A, effective April 3, 1978), the entire site is located within Zone C, areas of minimal flooding (Figures 3A and 3B). Zone C is considered to be outside of the 500-year floodplain. 3.2 State-listed Rare Species Habitat According to the most recent version of the Massachusetts Natural Heritage Atlas (2017), the proposed trail is not in proximity to Estimated Habitat of Rare Wildlife and Priority Habitat of Rare Species as designated by the Massachusetts Natural Heritage and Endangered Species Program (NHESP)(Figure 4). 3.3 Wetland Resource Areas 3.3.1 Resource Area Delineation Methodology Wetland resource areas were identified by Horsley Witten Group, Inc. (HW) wetlands biologists during site visits in March 2015 with supplemental site visits in August & September 2017. Several segments of Bordering Vegetated Wetlands as well as the associated buffer zone, and a segment of Riverfront Area were identified within the project area. HW followed wetland resource area identification and on-site delineation procedure guidelines described in the Massachusetts Department of Environmental Protection (DEP) handbook, entitled Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act (March, Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 4 of 22 1995), the Massachusetts Wetlands Protection Act Regulations, and the City of Northampton Wetland Protection Ordinance. The limit of BVW is demarcated at the point where 50% or greater of the vegetation is considered wetland indicator species and where hydric conditions are encountered, and is marked with consecutively numbered, pink flagging stations. The mean annual high water line (MAHW) of a river is defined as “the line that is apparent from visible markings or changes in the character of soils or vegetation due to the prolonged presence of water and that distinguishes between predominantly aquatic and predominantly terrestrial land” (310 CMR 10.58(2)(a) 2). Pursuant to these regulations, field indicators of “bankfull conditions” (changes in slope, changes in vegetation, stain lines, top of point bars, changes in bank materials or bank undercuts) were used to determine the MAHW associated with an unnamed perennial stream originating from Rocky Hill Pond. MAHW is labeled with sequentially numbered, blue flagging stations. A brief description of the regulatory definitions and the observed resources areas is provided below. 3.3.2 Bordering Vegetated Wetland Bordering Vegetated Wetlands are defined under Massachusetts Wetlands Protection Act Regulations at 310 CMR 10.55(2)(a) as, “freshwater wetlands that border on creeks, rivers, streams, ponds and lakes. The types of freshwater wetlands are wet meadows, marshes, swamps and bogs. Bordering Vegetated Wetlands are areas where the soils are saturated and/or inundated such that they support a predominance of wetland indicator plants. The boundary of Bordering Vegetated Wetland is defined at 310 CMR 10.55 (2)(c) as the line within which 50% or more of the vegetational community consists of wetland indicator plants and saturated or inundated conditions exist.” The Northampton Wetlands Ordinance does not have a separate definition for BVW. The BVW consists of a series of hill-side seeps associated with an unnamed perennial stream that traverses the northwestern portion of the site. THE BVW is best described as a forested red maple swamp dominated by red maple (Acer rubrum) with a shrub community supporting winterberry (Ilex verticillata), arrowwood (Viburnum dentatum), nannyberry (Viburnum lentago), as well as clumps and patches of honeysuckle (Lonicera sp.) and occasional multiflora rose (Rosa multiflora). Sensitive fern (Onoclea sensibilis) was the dominant groundcover species observed during the site evaluation. Witch-hazel (Hamamelis virginiana) and sapling gray birch (Betula populifolia) were observed along the wetland boundary, as well as occasional entanglements of Oriental bittersweet (Celastrus orbiculatus). Areas in the maintained right-of-way consist of a low-growing shrub community/herbaceous- dominant plant community (e.g., Palustrine Scrub-Shrub Wetland (PSS) or Palustrine Emergent Wetland (PEM) communities) dominated by soft rush (Juncus effusus), meadowsweet (Spiraea Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 5 of 22 latifolia), sensitive fern, and purple loosestrife (Lythrum salicaria) with gray birch and bittersweet vines. Adjacent upland areas are dominated by eastern white pine (Pinus strobus) and mixed oak (Quercus spp.) with witch hazel dominating the shrub community. Flagging stations A1-A10; A11-A15; B1-B17; B-18-B23; C1-C-9; C10-C23; C24-C36; and E1- E43represent the extent of BVW along the proposed pathway footprint. 3.3.3 Riverfront Area Riverfront Area is defined at 310 CMR 10.58(2)(a) as, “land between a river’s mean annual high water line and a parallel line measured horizontally. The riverfront area may include or overlap other resource areas or their buffer zones. The riverfront area does not have a buffer zone.” According to 310 CMR 10.58(2)(a)(1), “A river is any natural flowing body of water that empties to any ocean, lake, pond, or other river which flows throughout the year.” Furthermore, 310 CMR 10.58(2)(a)(3) states that, “The riverfront area is the area of land between a river’s mean annual high-water line measured horizontally outward from the river and a parallel line located 200 feet away.” The Northampton Wetlands Ordinance does not have a separate definition for Riverfront Area. An unnamed perennial stream flows from Rocky Hill Pond, located to the northeast of the project site, to the south into Pynchon Meadows and ultimately into the Connecticut River. This stream is shown as perennial on the most recent USGS Topographic Map (Easthampton Quadrangle) and therefore meets the regulatory definition of a perennial stream with an associated Riverfront Area. Mean annual high water (MAHW) was identified in the field by HW to the northeast and approximately 40 feet lower in elevation than the existing gravel road. The 200-foot Riverfront Area measured extends beyond the existing gravel road. Flagging stations MAHW1-MAHW4 were placed at the limit of bankfull conditions along this stream. 4.0 PROPOSED PROJECT 4.1 Project Description The proposed 0.50-mile Rocky Hill Greenway Multi-Use Trail will be constructed of bituminous asphalt pavement and will vary in width between 10 and 16 feet to accommodate site conditions. At its northern end, off of Rocky Hill Road, the trail will following the existing gravel driveway and will be 16 feet wide; this portion of the trail will act as a shared multi-use trail and driveway, allowing restricted vehicle access to the existing gas pumping station. The trail will then narrow to ten feet in width at the wetland crossing, and will be limited to pedestrians and bicycles for the remaining length of the spur trail to the junction with the existing Manhan Rail Trail. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 6 of 22 The proposed project also includes retaining walls, culvert replacements, and stormwater management areas. Retaining walls are only proposed at the HC parking spot. New culverts are proposed to replaced undersized existing culverts or in locations that the trail crosses existing drainage ways/ditches. For the trail section that is proposed outside an existing gravel trail or driveway (south of the overhead wire easement crossing) we are proposing to manage stormwater via a vegetated swale. Provisions for construction will include a Stormwater Pollution Prevention Plan (SWPPP) that must be followed by the Contractor, and will be provided under separate cover. For work within the resource area, the SWPPP will require the Contractor to implement measures to ensure the protection outside the limit of work that will include: •Rubber tire track machinery; •Swamp mats for temporary access over intermittently flowing resources; •Erosion control measures; •Stockpiling outside the resource area; •Construction timing; and •Other measures as described in the Project Plans and SWPPP. Details of the proposed project are provided on the enclosed site plans prepared by HW, entitled “Rocky Hill Greenway Multi-Use Trail, Northampton, Massachusetts” (dated March 2016). 4.2 Project Alternatives The City explored several alternative pathway locations including different routes as well as different materials and designs, in addition to a No-Build alternative, in order to avoid and minimize impacts within wetland resource areas while still resulting in an economically viable project. 4.2.1 Propose Project and Preferred Alternative The preferred alternative is the proposed project which utilizes an existing gravel driveway and existing footpath. It is the preferred alternative because it advances the goals of the City of Northampton to develop multi-use trails for easy and safe public access. The proposed project site is located strategically between a residential neighborhood and an existing trail and has part of a trail already built. Direct resource area impacts have been minimized by following the existing access driveway and following the existing gravel footpath to the extent practicable. Additionally, the path meanders through the wooded area to avoid impacts to the wetlands and other natural resources as much as possible. All construction-related temporary impacts will be restored upon completion of that portion of the pathway, and all construction staging areas will be located outside of wetland resource areas. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 7 of 22 4.2.2 Alternative Trail Location The City considered establishing a bike route along the existing surface roads (along Route 66/Chapel Street to West Street to the intersection with South Street/Route 10), by creating a bike lane to establish a connection with the Manhan Rail Trail. This would increase connectivity to an existing trail and would reduce wetland resource impacts, however it would not meet the goals to reduce bicycle and pedestrian exposure to vehicular traffic and improve safety. Additionally, it would require the existing roads to be reduced in width to accommodate a bike lane along the outer edge of the road. It would also not meet the City’s goal of increasing multimodal paths, as pedestrians would not likely use a bike lane along an existing roadway. Another alternative trail location that was considered was to stay along the utility easement. However, it was determined that there would be more considerable unavoidable wetland impacts with this footprint, as well as more work within Riverfront. 4.2.3 No-Build Alternative A No-Build alternative would not result in impacts to wetland resources; however, this would not meet the project purpose of extending a network of safe multi-modal trails in the City. 4.3 Affected Jurisdictional Areas Given the preferred location of the trail, portions of the project will necessitate work within wetland resource areas as well as within the associated buffer zone. These impacts have been avoided and minimized to the extent practicable by following the existing gravel roadway and an existing gravel footpath that traverses the wetland areas; however, portions of the proposed activities will occur within BVW and Riverfront Area, and within the locally-regulated 100-foot buffer to the BVW. Specifically, the proposed trail will directly impact 1,573 SF of BVW; a total of 188 linear feet of the path will occur within BVW. Approximately 40,924 SF of the 100-foot buffer to BVW will also be directly impacted by the proposed trail. In addition, approximately 19,114 SF of Riverfront Area, much of which is previously-disturbed, will be impacted by the proposed project. Table 1.

Page 8 of 22 A discussion on how the proposed project will avoid and minimize these impacts, as well as the proposed mitigation measures, including wetland replacement, is provided below. 5.0 PROTECTION OF RESOURCE AREA INTERESTS As indicated above, the proposed project will result in unavoidable activities will occur within BVW and Riverfront Area, as well as within the locally-regulated 10-foot buffer zone to BVW. A discussion of how the proposed project is designed to meet the performance standards under the Massachusetts Wetlands Protection Act Regulations and the City of Northampton Wetlands Ordinance (Chapter 337 of the Northampton Administrative Code) and regulations follows. 5.1 Bordering Vegetated Wetland – Wetland Replacement The following performance standards, as stated in 310 CMR 10.55(4), will be met to the extent practicable for work within BVW. Direct impacts within BVW will occur where the trail traverses a segment of BVW that currently spans across an existing gravel footpath. A total of 1,573 SF of BVW will be mitigated through the creation of a wetland replacement area approximately 2,680SF. As noted above, impacts to the wetland area have been avoided and minimized to the extent practicable, through the project design. Proposed wetland replacement area is designed to meet the performance standards under 310 CMR 10.55(4)(b)(1 through 7) as well as the provisions set forth by MassDOT for wetland replacement. Wetland replacement activities will generally include the removal of fill material and debris as well as existing vegetation within the footprint of the wetland replacement area, regrading and establishment of a connection to the existing intermittent channel and to the hillside seeps, introduction of high-organic content soils, introduction of coarse woody debris or boulders to improve habitat diversity, stabilization of disturbed soils with native seed mixes, and revegetation of wetland area with native plants to provide for a 75% native plant community within all impacted areas after two growing seasons (as required under 310 CMR 10.55(4)(b)(6)). A qualified professional (Wetlands Specialist) will oversee all phases of the wetland restoration efforts to ensure that requirements set forth in the proposed plan are met (see below). This individual will also be granted the discretion to make slight field adjustments to ensure wetland replacement success. This wetland replacement plan was developed based upon observations made by HW of existing conditions and is modeled after the Massachusetts Inland Wetland Replication Guidelines (March 2002) prepared by MassDEP (see attached checklist). The replacement plan is also designed to meet the regulatory criteria for wetland replacement set forth in 310 CMR 10.55(4)(b)(1) through (7).Details of these activities are provided on Sheet C-16 of the enclosed plan set entitled “Multi-Use Rocky Hill Greenway, Northampton, Massachusetts” prepared by HW and dated April 2016. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 9 of 22 Details of the proposed wetland replacement are provided in Appendix B. 5.2 Riverfront Area Redevelopment Activities within Riverfront Area will occur outside of the 0-100-foot Riverfront Area, and will occur within previously degraded areas including the existing access road. The following performance standards for redevelopment in Riverfront Area will be met for work within Riverfront Area. (a) At a minimum, proposed work shall result in an improvement over existing conditions of the capacity of the riverfront area to protect the interests identified in M.G.L. c. 131 § 40. Work within the outer Riverfront Area will involve re-use of en existing gravel (degraded) roadway. As part of the proposed project, existing culverts will be replaced to accommodate existing flows across the access road and footpath. A portion of the proposed wetland replacement areas will be located in Riverfront Area where materials from previous clearing activities had been dumped. Invasive species will be managed as part of the wetland replacement activities. (b) Stormwater management is provided according to standards established by the Department. Stormwater management measures will be provided to the extent practicable, although these measures will occur outside of Riverfront Area. (c) Within 200 foot riverfront areas, proposed work shall not be located closer to the river than existing conditions or 100 feet, whichever is less, or not closer than existing conditions within 25 foot riverfront areas, except in accordance with 310 CMR 10.58(5)(f) or (g). The proposed project will occur within Riverfront Area along existing paved or otherwise degraded Riverfront Area, but no closer to the river than under existing conditions with the exception of the wetland replacement areas. No work will occur within the inner 0-100-foot Riverfront Area. (d) Proposed work, including expansion of existing structures, shall be located outside the riverfront area or toward the riverfront area boundary and away from the river, except in accordance with 310 CMR 10.58(5)(f) or (g). The proposed project will occur along existing paved or otherwise degraded Riverfront Area but no closer to the unnamed perennial stream than under existing conditions with the exception of the proposed wetland replacement areas. (e) The area of proposed work shall not exceed the amount of degraded area, provided that the proposed work may alter up to 10% if the degraded area is less than 10% of the riverfront area, except in accordance with 310 CMR 10.58(5)(f) or (g). Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 10 of 22 Not applicable. The Project will result in redevelopment of an existing compacted gravel roadway. Approximately 23 percent (19,114 SF) of the Riverfront Area on this lot (82,137 SF) is currently degraded. Portions of the proposed wetland replacement areas will result in creation of wetland areas within Riverfront Area that is currently strewn with debris. Invasive species will be managed as part of the wetland replacement activities. (f) When an applicant proposes restoration on-site of degraded riverfront area, alteration may be allowed notwithstanding the criteria of 310 CMR 10.58(5)(c), (d), and (e) at a ratio in square feet of at least 1:1 of restored area to area of alteration not conforming to the criteria. Areas immediately along the river shall be selected for restoration. Alteration not conforming to the criteria shall begin at the riverfront area boundary. Restoration shall include: 1.removal of all debris, but retaining any trees or other mature vegetation; 2.grading to a topography which reduces runoff and increases infiltration; 3.coverage by topsoil at a depth consistent with natural conditions at the site; and 4.seeding and planting with an erosion control seed mixture, followed by plantings of herbaceous and woody species appropriate to the site; (Not applicable) (g) When an applicant proposes mitigation either on-site or in the riverfront area within the same general area of the river basin, alteration may be allowed notwithstanding the criteria of 310 CMR 10.58(5)(c), (d), or (e) at a ratio in square feet of at least 2:1 of mitigation area to area of alteration not conforming to the criteria or an equivalent level of environmental protection where square footage is not a relevant measure. Alteration not conforming to the criteria shall begin at the riverfront area boundary. Mitigation may include off-site restoration of riverfront areas, conservation restrictions under M.G.L. c. 184, §§ 31 to 33 to preserve undisturbed riverfront areas that could be otherwise altered under 310 CMR 10.00, the purchase of development rights within the riverfront area, the restoration of bordering vegetated wetland, projects to remedy an existing adverse impact on the interests identified in M.G.L. c. 131, § 40 for which the applicant is not legally responsible, or similar activities undertaken voluntarily by the applicant which will support a determination by the issuing authority of no significant adverse impact. Preference shall be given to potential mitigation projects, if any, identified in a River Basin Plan approved by the Secretary of the Executive Office of Environmental Affairs. (Not applicable) 5.3 BVW 100-Foot Buffer Zone The Northampton Wetlands Ordinance maintains a 100-foot buffer zone around BVW. Activities associated with this project will occur within the buffer zone by necessity of the Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc Page 11 of 22 project location. The multi-use trail is not anticipated to negatively impact the functions and values of the buffer. In accordance with the provisions in the City of Northampton Wetlands Ordinance Regulations, the Applicant requests relief from the standards for work within 100 feet of resource areas. Relief is requested because the required location of proposed trail is within portions of the buffer zone and BVW associated with an unnamed perennial stream. 5.4 Local Ordinance Performance Standards The Northampton Wetlands Ordinance contains performance standards for wetland resource areas and the 100-foot buffer to resource areas under §337-10(E). Included in this section is a provision for multi-use trails: “(2) The Commission shall not permit alteration within resource areas or their associated protected zones, subject to the following exceptions: … (c) Limited projects, as defined by the Massachusetts Wetlands Protection Act, and walking and multiuse trails designed for nonmotorized use.” The proposed Rocky Hill Greenway Multi-Use Trail falls under this provision. Proposed mitigation measures include providing wetland replacement (see above and in Appendix B) as well as providing improvements within the Riverfront Area (which also include portions of the 100-foot buffer zone to BVW. Additional discussion of how the proposed project is designed to meet the provisions of the local Ordinance is provided below. 5.4.1 Protecting Adjoining Premises from Detrimental Uses The abutting land uses around the property are primarily residential and wooded areas. The proposed project will not cause any detrimental uses to adjoining premises. In fact, the proposed trail will improve pedestrian and bicycle facilities by connecting the residential areas along Rocky Hill Road and Ice Pond Drive to the New Haven and Northampton Canal/Manhan Rail Trail. Local residents and visitors will benefit from being able to connect to these existing and future corridors more directly and with limited interaction with vehicular traffic. 5.4.2 Minimizing and Mitigating Traffic Impacts The proposed project is not anticipated to add to traffic congestion issues in the area. It will include 4 foot-wide shared shoulders marked for bicycle accommodation along Rocky Hill Road to connect the neighborhood at Ice Pond Drive. Secondary asset improvements include new project signage, restriping of Rocky Hill Road between Ice Pond Drive and the proposed trailwill be necessary to maintain appropriate lane and shoulder widths for bicycle accommodation adjacent to the project. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 12 of 22 5.4.3 Promoting Harmonious Relationships between Structures and Open Space The proposed project is designed to enhance the City’s commitment to provide alternatives for non-vehicular travel and to be consistent with the goals detailed in the City of Northampton Open Space, Recreation, and Multiuse Trail Plan (2011-2018). Additionally, the project is designed to minimally impact the surrounding natural resources. 5.4.4 Protecting the General Welfare As indicated above, the portion along Rocky Hill Road and access to the trail will be well marked. All proposed trail grades are 4.5% or less and areas spanning a culvert are proposed to have pedestrian barriers as well as sections with slopes greater than 3:1. 5.4.5 Avoiding Overload on City Resources and Mitigating Impacts The proposed project will reduce overload on City resources by providing additional non- vehicular transportation opportunities thereby mitigating congestion and vehicular emissions. 5.4.6 Promoting City Planning Objectives The proposed project is in keeping with the goals and objectives of the City of Northampton Open Space, Recreation, and Multiuse Trail Plan as well as the Northampton Community Plan to maintain vibrant urban centers, develop multi-use trails for easy public access, and create recreational opportunities while protecting valuable habitat and natural resources. 5.4.7 Meeting Zoning Requirements The proposed project meets the zoning requirements, which consist of Business Park (BP), General Industry (GI), Suburban residential (SR), and Farms, Forest, Rivers (FFR). Which are all compatible with a municipal facility that is noncommercial recreational. 5.5 Erosion and Sedimentation Control The Applicant proposes to protect the resource areas by implementing a sedimentation and erosion control program for the project. A sediment and erosion control barrier consisting of siltation sock (also referred to as mulch sock or silt sock) will be placed at the limit of work and/or as shown in the project plans. Erosion control barriers will remain in place and will be maintained in good condition until all work is complete and all soils have been stabilized. A temporary access way (also referred to as a haul road) of natural mulch material will be placed within the resource area to facilitate the installation of the helical piles and contain the work area within the designated limits. 6.0 STORMWATER MANAGEMENT The proposed project meets the definition of a mix of development and redevelopment under the Massachusetts Stormwater Handbook - Stormwater Management Standards (Stormwater Handbook). Per the Stormwater Handbook the pedestrian trail project is subject to the Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 13 of 22 Standards to the maximum extent practicable. We offer the following responses with respect to meeting the Stormwater Standards: Standard 1. No new stormwater conveyances (e.g. outfalls) may discharge untreated stormwater directly to or cause erosion in wetlands or waters of the Commonwealth. The bicycle/pedestrian trail is designed such that no new stormwater conveyances will result in any erosion or sedimentation to adjacent resource areas. Stormwater runoff from the paved bicycle trail will be collected and/or filtered by surface stabilized grass swales/channels, grassed filter strips, and/or stone (riprap) slopes/check dams that will promote sediment/debris removal and energy dissipation of the runoff prior to discharging to the down gradient wetland areas. Standard 2. Stormwater management systems shall be designed so that post-development peak discharge rates do not exceed pre-development peak discharge rates. This Standard may be waived for discharges to land subject to coastal storm flowage as defined in 310 CMR 10.04. Proposed best management practices have been included to maintain post-development peak discharge rates equal to pre-development rates to the maximum extent practicable. Steep sections of the paved bike trail will also be cross sloped to sheet runoff to grassed swales located along the shoulders to reduce concentrated flows. Grass swales are equipped width stone check dams to further reduce stormwater velocity and flow and promote filtering and recharge to groundwater. Standard 3. Loss of annual recharge to groundwater shall be eliminated or minimized through the use of infiltration measures including environmentally sensitive site design, low impact development techniques, stormwater best management practices, and good operation and maintenance. At a minimum, the annual recharge from the post-development site shall approximate the annual recharge from pre-development conditions based on soil type. This Standard is met when the stormwater management system is designed to infiltrate the required recharge volume as determined in accordance with the Massachusetts Stormwater Handbook. The use of existing and proposed drainage swales and stone shoulders will result in runoff sheet flow from the new paved trail prior to discharging to resource (Note: this runoff is considered free from any vehicular activity pollutants). Runoff that sheet flows over pervious surfaces prior to discharge to resource areas is an acceptable method for stormwater recharge according to the Stormwater Handbook. Therefore, annual recharge from the proposed bicycle trail will be approximately equal to or slightly greater than existing recharge volumes. Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 14 of 22 Standard 4. Stormwater management systems shall be designed to remove 80% of the average annual post-construction load of Total Suspended Solids (TSS). This Standard is met when: •Suitable practices for source control and pollution prevention are identified in a long- term pollution prevention plan, and thereafter are implemented and maintained; •Structural stormwater best management practices are sized to capture the required water quality volume determined in accordance with the Massachusetts Stormwater Handbook; and •Pretreatment is provided in accordance with the Massachusetts Stormwater Handbook. A general long-term pollution prevention plan is provided below. The SWPPP will provide resource protection requirements for the construction period. The trail will not be subject to vehicle traffic and therefore will not be subject to sanding operations. For these factors the TSS loading will be equal or less in post construction. Standard 5. For land uses with higher potential pollutant loads, source control and pollution prevention shall be implemented in accordance with the Massachusetts Stormwater Handbook to eliminate or reduce the discharge of stormwater runoff from such land uses to the maximum extent practicable. If through source control and/or pollution prevention all land uses with higher potential pollutant loads cannot be completely protected from exposure to rain, snow, snow melt, and stormwater runoff, the proponent shall use the specific structural stormwater BMPs determined by the Department to be suitable for such uses as provided in the Massachusetts Stormwater Handbook. Stormwater discharges from land uses with higher potential pollutant loads shall also comply with the requirements of the Massachusetts Clean Waters Act, M.G.L. c. 21, §§ 26-53 and the regulations promulgated thereunder at 314 CMR 3.00, 314 CMR 4.00 and 314 CMR 5.00. Not applicable. No area on the proposed site has been designated as a land use with higher potential pollutant loads. Standard 6. Stormwater discharges within the Zone II or Interim Wellhead Protection Area of a public water supply, and stormwater discharges near or to any other critical area, require the use of the specific source control and pollution prevention measures and the specific structural stormwater best management practices determined by the Department to be suitable for managing discharges to such areas, as provided in the Massachusetts Stormwater Handbook. A discharge is near a critical area if there is a strong likelihood of a significant impact occurring to said area, taking into account site-specific factors. Stormwater discharges to Outstanding Resource Waters and Special Resource Waters shall be removed and set back from the receiving water or wetland and receive the highest and best practical method of treatment. A “storm water discharge” as defined in 314 CMR 3.04(2)(a)1 or (b) to Notice of Intent Project Narrative Northampton, MA Horsley Witten Group, Inc. Page 15 of 22 an Outstanding Resource Water or Special Resource Water shall comply with 314 CMR 3.00 and 314 CMR 4.00. Stormwater discharges to a Zone I or Zone A are prohibited unless essential to the operation of a public water supply. Not applicable. Standard 7. A redevelopment project is required to meet the following Stormwater Management Standards only to the maximum extent practicable: Standard 2, Standard 3, and the pretreatment and structural best management practice requirements of Standards 4, 5, and 6. Existing stormwater discharges shall comply with Standard 1 only to the maximum extent practicable. A redevelopment project shall also comply with all other requirements of the Stormwater Management Standards and improve existing conditions. Portions of the project are redevelopment. These sections are between Rocky Hill Road and the gas substations and the maintenance path servicing the overhead wire easement. The section of trail that traverses the wooded section is considered new development and therefore we have included stormwater management for this section. Standard 8. A plan to control construction-related impacts including erosion, sedimentation and other pollutant sources during construction and land disturbance activities (construction period erosion, sedimentation, and pollution prevention plan) shall be developed and implemented. The erosion and sediment control devices that will be implemented during construction of the project are shown on the site plans. They include siltation socks adjacent to all resource areas and designated stockpile/staging areas, retaining walls, and mulch surface treatment for disturbed areas. Details are provided on the site plans. Standard 9. A long-term operation and maintenance plan shall be developed and implemented to ensure that stormwater management systems function as designed. An operations and maintenance plan will be included in the Stormwater Pollution Prevention Plan (SWPPP) that will be included in the Contract Documents. Standard 10. All illicit discharges to the stormwater management system are prohibited. There will be no illicit discharges to any resource area or stormwater management system/structure as part of this project. 7.0 POST CONSTRUCTION OPERATION AND MAINTENANCE In conformance with Standard 9 of the Stormwater Standards we offer the following information for Post Construction Operation and Maintenance of the stormwater system associated with the proposed Multi-Use Trail.

This area is mapped for wood turtle (Glyptemys insculpta), a Massachusetts Species of Special Concern. The wood turtle is protected under the Massachusetts Endangered Species Act (MESA) (M.G.L. c. 131A) and it’s implementing regulations (321 CMR 10.00). The wood turtle is a medium-sized turtle (14-20 cm, 5.5-8 in) that can be readily recognized by its sculpted shell and orange color on its legs and neck. The carapace is rough and each scale rises upwards in an irregularly shaped pyramid of grooves and ridges. This species spends much of its time in or near flowing waters. It can also be seen in forests and grasslands; however, this species is rarely found more than 300 meters (1000 ft) from flowing water. This species is typically active from mid-March through October. During the winter months the turtle hibernates in flowing rivers and perennial streams. This species will also spend the hottest parts of the summer in aestivation (prolonged dormancy or torpor during hot or dry periods). Given the range of the wood turtle and the proximity of the proposed project to the unnamed perennial stream and surrounding wetland areas, it will be necessary to implement a rare species protection plan to ensure that the local population of this species is not adversely impacted. The plan will ensure that encounters with this species during construction are avoided, or depending upon the construction timing, relocated if found within the limit of work prior to the start of construction.

APPENDIX A Wetland Mitigation Plan Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 1 of 11 APPENDIX A Wetland Replacement Plan Rocky Hill Greenway Multi-Use Trail Northampton, MA March 2019 1.0 Introduction The City of Northampton proposes the Rocky Hill Greenway Multi-Use Trail, a 2,630 linear foot (0.50 mile) multi-use trail designed as a spur trail to connect two existing trails in the neighborhood. The proposed project is located entirely within a City-owned parcel situated between Rocky Hill Road (MA Route 66) and Easthampton Road (MA Route 10) in Northampton, Massachusetts. The proposed trail project will improve pedestrian and bicycle facilities by connecting the residential areas along Rocky Hill Road and Ice Pond Drive to the New Haven and Northampton Canal /Manhan Rail Trail. Bicyclists and pedestrians will benefit from being able to connect to these corridors more directly and with limited interaction with vehicular traffic along these two major roadways, providing a safer and more direct route to the existing rail trail. Additionally, the proposed trail will provide access to an eventual multi-use trail serving the southwestern and western half of the City, which is not currently served by any multi-use trails. The proposed project will result in unavoidable impacts to Bordering Vegetated Wetland (BVW). Alterations to BVW have been avoided and minimized to the extent practicable given the site constraints; however, some BVW alteration is necessary to meet the project goals. The proposed trail is sited to maximize the reuse of existing disturbed areas by reusing an existing gravel access driveway within the Massachusetts Electric Company easement and following the existing gravel footpath that currently traverses the BVW. Alternate trail locations would result in even greater wetland impacts, as the BVW at this site consists of a series of hill-side seeps along the slopes leading downgradient toward an unnamed perennial stream. The Applicant proposes to provide wetland mitigation for unavoidable wetland impacts by creating two wetland replacement areas totaling approximately 2,680 SF adjacent to the proposed multi-use trail to the north/northeast of the existing gravel roadway, near wetland flags A11-A12 and A13-A14 and flags B22-B23 where hillside seeps occur along a small drainage channel. Details of the proposed mitigation areas are provided below and are shown on Sheet Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 2 of 11 8 of the project plans prepared by Horsley Witten Group, Inc.(HW), entitled “Rocky Hill Greenway Multi-Use Trail, Northampton, Massachusetts” (dated April 2016). 2.0 Wetland Replacement Details Wetland replacement activities will generally include the removal of fill material and debris as well as existing vegetation within the footprint of the two wetland replacement areas, regrading and establishment of a connection to the existing intermittent channel and to the hillside seeps, introduction of high-organic content soils, introduction of coarse woody debris or boulders to improve habitat diversity, stabilization of disturbed soils with native seed mixes, and revegetation of wetland areas with native plants to provide for a 75% native plant community within all impacted areas after two growing seasons (as required under 310 CMR 10.55(4)(b)(6)). A qualified professional (Wetlands Specialist) will oversee all phases of the wetland restoration efforts to ensure that requirements set forth in the proposed plan are met. This wetland replacement plan was developed based upon observations made by HW of existing conditions and is modeled after the Massachusetts Inland Wetland Replacement Guidelines (March 2002) prepared by MassDEP). The replacement plan is also designed to meet the regulatory criteria for wetland replacement set forth in 310 CMR 10.55(4)(b)(1) through (7) as well as the provisions set forth by Massachusetts Department of Transportation (MassDOT) for wetland replacement. 2.1 Wetland Specialist As required by MassDOT and in accordance with the MassDOT specifications, a Wetland Specialist will be retained to oversee all aspects of the wetland replacement. This individual must have a minimum of 5-years experience in wetland replacement and will be responsible for the following, including, but not limited to, finalizing the location of the replacement areas, overseeing siltation controls, final grading, overseeing plantings, long-term monitoring of plant growth and any invasives, and preparing and submitting monitoring reports. This individual will also be granted the discretion to make slight field adjustments to ensure wetland replacement success. 2.2 Erosion and Sedimentation Control Prior to the commencement of any wetland replacement activities, a sedimentation and erosion control barrier consisting of staked siltation fencing or staked silt socks will be installed along the existing wetland boundary to protect the adjacent areas during earth-moving activities. Erosion control barriers may also serve as the downgradient barrier for rare species protection, and the locations and type of barriers will be coordinated with the Massachusetts Natural Heritage and Endangered Species Program (NHESP) and the Conservation Commission. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 3 of 11 Erosion control barriers will be regularly inspected and properly maintained during and after construction, including after every storm event, pursuant to specifications. Devices will be removed at the end of the two-year monitoring period if vegetation has been successfully established and sediments are stabilized. 2.3 Site Preparation and Excavation Following installation of the sedimentation barrier, vegetation and soils within the proposed replacement areas will be removed using mechanized equipment, creating two areas totaling of approximately 2,680 SF of wetland area. Sediments and vegetation removed from this area will be transported off-site to a suitable disposal facility; soils may be re-used on-site as fill material if appropriate. Miscellaneous debris observed within the replacement areas will be removed and disposed of off-site at a suitable facility. At the discretion of the Wetland Specialist, suitable debris may be retained and stockpiled nearby for re-introduction in the replacement areas following final grading and introduction of wetland soils to enhance wildlife habitat. The replacement areas will be designed to mimic the topography of the adjacent BVW; the elevations specified on the replacement BVW as shown on the attached plans are based on observations of the adjacent natural wetlands. 2.4 Soils Depending upon the condition of the underlying soils within the replacement areas, the areas will either be lightly regraded and/or supplemented as necessary. Soils within the impacted BVW will be reused as feasible, and will not be compacted or grubbed in order to retain soil structure and the existing seedbank/rootstock. It is anticipated that these would need to be supplemented to accommodate for the larger replacement areas. If it is determined that soils need to be supplemented, the replacement areas would be over- excavated by approximately 6-12 inches to allow for introduction of a layer of low permeability soils and organic-rich sediments to support the proposed wetland plant community. It will be ensured that the completed wetland replacement areas will tie into the adjacent wetland grades to allow for an unrestricted hydrologic connection between the existing wetland area and the replacement areas. Variable microtopography within the replacement areas will be created to enhance habitat diversity and improve the hydrologic connection with groundwater. The organic-rich soils will be obtained from a commercial source, will be certified as weed-free, and will be allowed to settle for a minimum of 48 hours prior to introducing plants. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 4 of 11 2.5 Wetland Replacement Area Plantings Following placement of wetland soils and re-grading, native saplings, shrubs, and herbaceous materials obtained from local nursery stock will be introduced within the replacement areas. Proposed species were selected to be compatible with the natural wetland and designed to enhance the existing vegetation community. Proposed species for the wetland and adjacent buffer include, but are not limited to, red maple (Acer rubrum), gray birch (Betula populifolia), iron wood (Carpinus caroliniana), highbush blueberry (Vaccinium corymbosum), spicebush (Lindera benzoin), winterberry (Ilex verticillata), arrowwood (Viburnum dentatum), nannyberry (Viburnum lentago), meadowsweet (Spiraea latifolia), steeplebush (Spiraea tomentosa), cinnamon fern (Osmunda cinnamomea), sensitive fern (Onoclea sensibilis), and Cardinal flower (Lobelia cardinalis) in accordance with the specifications provided on the plans. Tree species will be planted singly, while shrubs and container-grown herbaceous plants will be planted in clusters to provide a mosaic of wetland plantings. Plantings will be installed near the beginning or the end of the growing season for Hampshire County, MA (April 29 – October 12; USDA, 2002), to ensure greater plant survival. Planting specifications are provided on Sheet C- 16 of the project plans. Proposed plantings are designed to provide a densely vegetated forested swamp community upon full grow-out. 2.6 Stabilization with Wetland Seed Mix A wetland seed mix will be introduced to stabilize disturbed soils within the wetland replacement areas. Appropriate seed mixes that contain native seeds suitable for most wetland mitigation sites are commercially available. A native seed mix, such as the “New England Wetmix,” supplied by New England Wetland Plants, Inc. (www.newp.com) or acceptable equivalent, will be introduced to stabilize the soil surface and enhance the wetland plant community to ensure a 75% native wetland plant cover after two growing seasons. According to the NEWP website, the New England Wetmix “contains a wide variety of native seeds that are suitable for most wetland restoration sites that are not permanently flooded. All species are best suited to moist ground as found in most wet meadows, scrub shrub, or forested wetland restoration areas.” Following the planting of woody vegetation and fern species, the seed mix will be introduced at the recommended application rate of 1 LB/2500 SF (or 18 lbs/acre) and lightly raked in as recommended. All plantings will be watered during the two to three week grow-in period as necessary. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 5 of 11 Species included within this wetland seed mix include: fox sedge (Carex vulpinoidea), lurid sedge (Carex lurida), blunt broom sedge (Carex scoparia), sensitive fern (Onoclea sensibilis), blue vervain (Verbena hastata), hop sedge (Carex lupulina), green bulrush (Scirpus atrovirens), nodding bur marigold (Bidens cernua), bristly sedge (Carex comosa), fringed sedge (Carex crinita), American mannagrass (Glyceria grandis), wool grass (Scirpus cyperinus), soft rush (Juncus effusus), spotted Joe Pye weed (Eupatorium maculatum), boneset (Eupatorium perfoliatum), mud plantain (Alisma subcordatum), New England aster (Aster novae-angliae), rattlesnake grass (Glyceria canadensis), purplestem aster (Aster puniceus), soft stem bulrush (Scirpus validus), blueflag (Iris versicolor), swamp milkweed (Asclepias incarnata), and monkey flower (Mimulus ringens). Upper reaches and side slopes along the existing access driveway/proposed trail will be stabilized with a similar native seed mix such as the New England Conservation/Wildlife Mix. According to the specification sheet, this seed mix “provides a permanent cover of grasses, wildflowers, and legumes. For both good erosion control and wildlife habitat value. The mix is designed to be a no maintenance seeding, and is appropriate for cut and fill slopes, detention basin side slopes, and disturbed areas adjacent to commercial and residential projects” at the recommended application rate of 25 lbs/acre (1,750 SF/lb). Species contained in this native seed mix include: Virginia wild rye (Elymus virginicus), little bluestem (Schizachyrium scoparium), big bluestem (Andropogon gerardii), creeping red fescue (Festuca rubra), switch grass (Panicum virgatum), partridge pea (Chamaecrista fasciculata), deer tongue (Panicum clandestinum), Indian grass (Sorghastrum nutans), ox eye sunflower (Heliopsis helianthoides), common milkweed (Asclepias syriaca), spotted Joe Pye weed (Eupatorium maculatum), grass leaved goldenrod (Euthamia graminifolia), blue vervain (Verbena hastata), New England aster (Aster novae-angliae), and early goldenrod (Solidago juncea). 2.7 Invasive Species Management HW observed the presence of occasional non-native invasive species during the initial site survey, including, but not limited to, honeysuckle (Lonicera sp.), Oriental bittersweet (Celastrus orbiculatus), and purple loosestrife (Lythrum salicaria). These species are capable of spreading rapidly through and extensive seedbank, and/or rhizomes and can leave a long-lived seed bank in the soil. As these species are considered either invasive, likely invasive, or potentially invasive in Massachusetts, precautions will be taken to minimize the re-introduction or spread of this species within the newly created wetland replacement areas. Any observed seedlings found within the replacement areas during the grow-in and monitoring periods will be pulled by hand, bagged, and disposed of properly. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 6 of 11 2.8 Monitoring The wetland replacement areas will be monitored twice annually (approximately early to mid- June and early to mid-September) for a minimum of two growing seasons to assess the relative success of the replacement wetlands. Semi-annual site inspections conducted during late spring and late summer will include an assessment of the relative health and vigor of the planted vegetation, percent vegetative cover, percent cover of wetland species, and general compliance with the performance standards. Written reports detailing the findings of each monitoring event will be submitted on an annual basis for two years, to the Northampton Conservation Commission. Photographic documentation will be incorporated within the monitoring reports and photographs will be taken from pre-established vantage points for consistency between monitoring events. Recommendations will be made for the replacement of dead or dying plants, and any additional remediation, as necessary. 3.0 Wetland Replacement Sequence of Construction 1). A qualified wetland professional, Wetland Specialist (WS), will be identified to monitor all phases of construction of the replacement areas including, but not limited to, installation of sedimentation control barriers, removal of fill materials and debris, excavation of sub- base materials, soil augmentation, revegetation, reseeding, and implementation of the monitoring plan. The WS will photo-document all phases of the restoration process and provide reports to the Northampton Conservation Commission. 2). The WS will meet on-site with the Conservation Commission or its designated Agent to review all components of the replacement areas prior to the start of wetland replacement activities, to discuss any slight deviations that may need to be considered, and to establish the reporting protocol and schedule. 3). Prior to construction of wetland replacement areas, wetland flags will be refreshed as needed to define the boundary of the proposed wetland replacement areas as shown on the site plans. 4). A sedimentation and erosion control barrier will be installed along the wetland boundary in accordance with the manufacturer’s specifications, by a qualified contractor who is experienced with installation of such sedimentation and erosion control barriers and who is also generally experienced in wetland replacement practices. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 7 of 11 5). Debris within the restoration area will be removed using mechanized equipment such as a bobcat. All debris will be disposed of at a proper facility in accordance with all state and local laws, unless determined by the WS to be suitable for reuse in the mitigation areas. 6). Existing vegetation within the replacement areas will be cut, removed (or stockpiled for reuse if suitable), and the root systems grubbed and removed. 7). The wetland replacement areas will be roughly excavated to a depth of six to 12 inches below grade to ensure proper hydrological connection to groundwater within the final grade of the replacement areas. 8). Clean, weed-free high-organic soils will be introduced within the replacement areas and regraded, incorporating slight undulating pit-and-mound microtopography throughout to mimic conditions within the undisturbed wetland. The exact configuration of the replacement areas will be determined in the field by the WS in coordination with the contractor. Sediments will be allowed to settle for a minimum of 48 hours prior to planting. 9). A sedimentation and erosion control barrier will be installed along the upland areas and the newly created wetland boundaries to protect the replacement areas during grow-in period. 10). Following settling of introduced sediments, small rocks and/or fallen woody debris will be placed within the replacement areas to provide added wildlife habitat. Additional habitat features may be incorporated (e.g., turtle nesting habitat) 11). Nursery grown native vegetation will be planted in accordance with the planting specifications, working from far interior portions of the restoration area outward. Seeding with appropriate seed mix will occur in a similar manner, such that newly planted vegetation and seed mix are not continually trampled once planted. All plantings will be conducted by a qualified landscaper or other qualified professional who has experience with wetland replacement areas. Any deviations from the specified planting list must be approved by the WS. 12). Note: All plantings should occur during the growing season for Hampshire County, Massachusetts, which occurs from April 29 through October 12 (USDA, 2002). Should the replacement activities commence outside of that timeframe, excavation and soil augmentation activities may occur at the discretion of the WS, however, plantings should not occur. Instead the area may be temporarily stabilized with a non-persistent annual rye or weed-free straw. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 8 of 11 13). All vegetation will be irrigated, particularly during dry periods, at the direction of the WS overseeing the wetland replacement efforts. 14). The downgradient erosion control barrier will be removed from existing wetland boundary once all soils are stabilized with vegetation. 15). The Contractor will inspect erosion and sediment control systems immediately after each significant rainfall and daily during prolonged rainfall events, and will make repairs immediately including the removal and disposal of accumulated sediments when they reach approximately one-half the height of the control system, and when directed by the WS. Control systems will be promptly replaced if fabric decomposes or system becomes ineffective prior to the expected usable life. 16). The WS will monitor the wetland replacement areas twice annually during the growing season for two growing seasons as required. Bi-annual site inspections will include an assessment of the relative health and vigor of the introduced plants, percent cover of vegetation, percent cover of wetland species, and general compliance with the performance standards under 310 CMR 10.55(4)(b)(1 through 7). Randomly distributed vegetation monitoring quadrats will be established within the wetland restoration areas to provide consistent data regarding the relative success of the wetland plant community and to confirm that they are meeting the 75 percent reestablishment standard. The WS will establish photographic stations in strategic locations throughout the replacement areas to ensure consistency among photo-documentation during the monitoring period. Monitoring forms such as the sample provided in DEP handbook will be used. Annual reports will be submitted to the Northampton Conservation Commission and to MassDEP. 4.0 Compliance with Wetlands Regulations The proposed wetland replacement areas are designed to comply with the regulations at 310 CMR 10.55(4)(b) (1 through 7). The regulations state, Notwithstanding the provisions of 310 CMR 10.55(4)(a), the issuing authority may issue an Order of Conditions permitting work which results in the loss of up to 5000 square feet of Bordering Vegetated Wetland when said area is replaced in accordance with the following general conditions and any additional, specific conditions the issuing authority deems necessary to ensure that the replacement area will function in a manner similar to the area that will be lost: 1.the surface of the replacement area to be created ("the replacement area") shall be equal to that of the area that will be lost ("the lost area"); Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 9 of 11 Combined, the proposed wetland replacement areas are 2,680 SF, providing an approximately 1.6:1 mitigation ratio to impacted BVW. This is slightly lower than the local mitigation requirement, but is designed in an area currently strewn with debris that was determined to be the most appropriate location for the proposed mitigation area. Additional mitigation would result in the removal of undisturbed forested buffer zone, areas that are also important for the protection of wetland resources. 2.the ground water and surface elevation of the replacement area shall be approximately equal to that of the lost area; 3.the overall horizontal configuration and location of the replacement area with respect to the bank shall be similar to that of the lost area; 4.the replacement area shall have an unrestricted hydraulic connection to the same water body or waterway associated with the lost area; The proposed replacement areas are located directly adjacent to two wetland segments and at the same or similar elevations. They are designed to mimic the adjacent hill-side seep wetlands. 5.the replacement area shall be located within the same general area of the water body or reach of the waterway as the lost area; The proposed wetland replacement areas are sited in an area directly adjacent to and north of the proposed wetland crossing and within the same approximate distance to the nearby unnamed perennial stream. 6.at least 75% of the surface of the replacement area shall be reestablished with indigenous wetland plant species within two growing seasons, and prior to said vegetative reestablishment any exposed soil in the replacement area shall be temporarily stabilized to prevent erosion in accordance with standard U.S. Soil Conservation Service methods; and The wetland replacement areas are designed to achieve a 75 percent or greater native wetland plant community after two growing seasons. Native plantings obtained from nursery stock are the same or similar in composition to species observed within the undisturbed wetland. Native seed mixes will ensure cover of native species as well as provide erosion control during the grow-in period. 7.the replacement area shall be provided in a manner which is consistent with all other General Performance Standards for each resource area in Part III of 310 CMR 10.00. Wetland Replacement Area Northampton, Massachusetts Horsley Witten Group, Inc. Page 10 of 11 In the exercise of this discretion, the issuing authority shall consider the magnitude of the alteration and the significance of the project site to the interests identified in M.G.L. c. 131, § 40, the extent to which adverse impacts can be avoided, the extent to which adverse impacts are minimized, and the extent to which mitigation measures, including replacement or restoration, are provided to contribute to the protection of the interests identified in M.G.L. c. 131, § 40. The proposed wetland replacement area is designed to be consistent with all other performance standards for freshwater wetlands, and will provide greater than 1:1 mitigation for lost wetlands that are currently disturbed (e.g., the gravel footpath that traverses the wetland area). Provisions have been incorporated to provide additional wildlife habitat features, and a monitoring plan has been established to control the spread of invasive species that have been observed in the vicinity. Further, a rare species protection plan has been drafted for review and approval by NHESP to ensure no adverse effects to the local rare species populations. An alternatives analysis of the project has been performed and it has been determined that the proposed project and preferred alternative is the only feasible alternative that will meet the project purpose. Measures to further minimize wetland impacts include incorporation of retaining walls in areas of the trail that abut or are in the vicinity of wetland resource areas. New culverts are proposed to replaced undersized existing culverts or in locations that the trail crossing existing drainage ways/ditches. Stormwater will be managed in accordance with the Massachusetts Stormwater Management Standards, incorporating a vegetated swale to manage runoff of new impervious surfaces.
