The brook bisects the former Pine Grove golf course, and eventually flows through Mass Audubon’s Arcadia Wildlife Sanctuary and into the Manhan River. Two intermittent stream tributaries of Nashawannuck Brook are located at the former Pine Grove golf course downstream of Old Wilson Road. The drainage area of Nashawannuck Brook is approximately 0.5 square miles at the point where the Brook exits the City-owned parcel. The site was significantly altered by the development of the golf course and associated support structures, leaving little of the natural landscape intact. The site is currently dominated by upland fairways transitioning to native vegetation, some linear forest features, and assorted hard structures. The City of Northampton purchased the former Pine Grove Golf Course and applied for and received a MA Municipal Vulnerability Preparedness Program Action Grant to complete a master plan for the site. The City also undertook initial restoration activities, including: removal of catch basins and drainage structures built to drain runoff from fairways and greens; scarification of former turf grass areas; and replanting of two upland fairway areas with seedlings of various native tree species. Nashawannuck Brook Dam is located on Nashawannuck Brook near the center of the project site. The earthen dam is approximately 150 feet long, with a 10-foot wide crest, and an impoundment with an area of approximately 0.5-acre. Nashawannuck Brook is listed as an intermittent stream (based on USGS topographic maps and the National Wetlands Inventory dataset) in this area although the channel appears to typically have flowing water. The dam is non-jurisdictional under the Massachusetts Dam Safety Regulations of 302 CMR 10.00 and, as such, is not monitored by the Office of Dam Safety for condition. Typical jurisdictional dams in Massachusetts have storage volumes of less than 15 acre feet or structural heights of less than six feet. Water flows out of the impoundment through an unmanaged water control structure that formerly housed boards for manipulating the water level in the impoundment. The outlet of the dam is a deteriorated corrugated metal pipe. Current access to the dam is from a pedestrian trail network on former golf cart paths, approximately 0.3 miles from the trailhead kiosk at Old Wilson Road. Figure 1 is a site locus showing the study area. Figure 2 is an orthographic image showing the potential Nashawannuck Brook Restoration area. 1.1 Site History The site where the Nashawannuck Brook dam is located was originally undeveloped wooded land that was then converted into the Pine Grove Golf Course beginning in the 1930s. The 118-acre site was constructed from west to east over the course of about 40 years. The site included an 18-hole golf course, a maintenance building, and a club house. The site included multiple access roads, parking areas, and buildings. Tile drains were installed throughout the site and the hydrology of the site was altered by altering/straightening the stream channel and construction of Nashawannuck Brook Dam to regulate water flow. The impoundment of Nashawannuck Brook dam is a man-made Section 1 Background Tighe&Bond Nashawannuck Brook Basis of Design Report 1-2 pond in the central area of the site. An irrigation pump house, which has since been removed, was originally located to the south of the pond. The pump was connected to two batteries and a 275-gallon diesel aboveground storage tank which were all located within the pump house and connected to the pump. Surrounding the site to the northeast, east, and southeast is undeveloped, wooded land. To the north and south of the site are rural residential properties and to the west is Old Wilson Road and undeveloped, wooded land. Over 100-acres of the site has since been purchased by the City of Northampton for the purpose of permanent conservation and restoration, focusing on the Nashawannuck Brook and surrounding wetlands, floodplains and wildlife habitats. Nashawannuck Brook is a small tributary to the Manhan River and the brook flows into the Arcadia Wildlife Sanctuary downstream of the site. Figure 1 in Appendix A shows a site location plan and Figure 2 in Appendix A shows an orthophotograph of the site. 1.2 Site Status The Nashawannuck Pond Dam is a non-jurisdictional dam. There is currently a walking path over the dam crest. Photo 1-1 and Photo 1-2 show overviews of the dam from upstream and downstream, respectively. Photo 1-1: Overview of Nashawannuck Brook Dam from Upstream Section 1 Background Tighe&Bond Nashawannuck Brook Basis of Design Report 1-3 Photo 1-2: Overview of Nashawannuck Brook Dam from downstream 1.3 Project Purpose and Need The Nashawannuck Brook Restoration was designated a Massachusetts Department of Fish and Game’s Division of Ecological Restoration (DER) Priority Project in January 2021. The removal of the Nashawannuck Brook Dam is one step in a potential larger restoration vision by the owner of Nashawannuck Brook Dam (the City of Northampton) and the project partner Massachusetts Audubon Society. The City of Northampton and its project partners are pursuing dam removal to restore ecological processes and aquatic connectivity on the site. The Nashawannuck Dam is no longer necessary to serve the irrigation purpose for which it was constructed, and removal of the dam is a critical component of the overall restoration planned for the site. Removal of dams is increasingly recognized as more beneficial than performing repairs in many instances in terms of both ecology and human experience. As such, the purpose of this assessment is intended to evaluate the feasibility of dam removal that would help restore Nashwannuck Brook to a more natural state in the area of the dam to promote sustainable flood mitigation, ecological restoration, and passive recreation. The goals of the overall former Pine Grove Golf Course property project are to:  Restore Nashwannuck Brook to a more natural ecological state  Preserve open space  Improve ecological function, aquatic conductivity, and habitat Section 1 Background Tighe&Bond Nashawannuck Brook Basis of Design Report 1-4  Enhance climate resilience through peak flood flow reduction and carbon capture and sequestration  Provide for passive recreation accessible through an established trail network  Augment the City’s existing Rocky Hill Greenway that abuts the parcel to the east and northeast The primary alternatives evaluated are the following: 1. A “full” dam removal removing the entire dam embankment 2. A “partial” dam removal where some of the dam embankment remains in place (multiple “partial” dam removal alternatives were considered) 3. No action (existing conditions) The goal of this report is to provide a brief basis of design which includes a summary of existing materials reviewed, data collection efforts performed, ecosystem and wildlife considerations and needs, sediment characterizations and management, hydrologic and hydraulic modeling, anticipated infrastructure concerns and constraints, evaluation of restoration approaches, and descriptions of proposed conceptual design. Tighe&Bond Nashawannuck Brook Basis of Design Report 2-1 Section 2 Data Collection and Analysis 2.1 Existing Materials Review The following key background information was collected and reviewed for this report:  Reports o Phase I Environmental Site Assessment 254 Old Wilson Road, Northampton, Massachusetts, prepared by O’Reilly, Talbot & Okun Associates, Inc., dated December 3, 2019 o Memorandum – Basis of Design for Restoration Nashawannuck Brook Restoration Project, prepared by GZA GeoEnvironmental, Inc., dated June 30, 2022 o Memorandum - Wetlands/ Ecological Conditions Update Nashawannuck Brook Restoration Project, prepared by GZA GeoEnvironmental, Inc, dated June 30, 2022 o Memorandum – Hydrologic and Hydraulic Models for Restoration Scenarios Nashawannuck Brook Restoration Project, Prepared by GZA GeoEnvironmental, Inc., dated June 1, 2022 o Geomorphic Assessment of Nashawannuck Brook, prepared by Field Geology Services, dated June 2022  Drawings o Plan of Land in Northampton, MA Control Survey Sketch, Prepared by Northeast Survey for Tighe & Bond, dated March 13, 2023.  Digital Data o StreamStats Program o MassDEP Oil or Hazardous Materials (OHM) Sites List o Relevant GIS data layers from Massachusetts Office of Geographic Information (MassGIS) 2.2 Data Collection 2.2.1 Survey Tighe & Bond conducted 3D laser scanning using a Trimble X7 to dimensionally document the existing conditions of the dam removal site, including:  The dam embankment  Three (3) control points  250 feet left and right of the existing impoundment Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-2  The stream corridor covering approximately 25-feet from the stream centerline extending 200 feet upstream of the dam impoundment and 200 feet downstream of the dam embankment Northeast Survey Consultants set three (3) control points with x, y, and z data for the study area. One of the points is the dam intake, and the other two are iron rods. These control points can be used for future surveys to tie into established horizontal and vertical datums. The Trimble X7 laser scanner is a high-precision device used to capture detailed 3D data of an object or environment. In the context of a topographic site map of existing conditions, the Trimble X7 scanner is used to capture the precise location and elevation of various features of the site, such as terrain, vegetation, buildings, and other man-made structures. To generate the topographic site map, the data collected by the Trimble X7 scanner was combined with the survey control. Tighe & Bond processed the point cloud data using Trimble RealWorks and developed a 3D viewer file and point cloud export file. The 3D viewer file combines the 3D point cloud with the panoramic photos the scanner takes at each station to generate a colorized 3D rendering of the area. This file allows the viewer to “walkthrough” each scan station, take measurements, and view the existing conditions with far greater detail than traditional photographs. The point cloud data was then imported into AutoCAD to develop the drawing base map. The survey base plan developed for the study area is shown in the preliminary design drawing described in Section 4. The base plan included one-foot contours, locations of dam components, inverts for culverts located downstream of Nashawannuck Brook Dam, and trees with diameters greater than 6-inches. 2.2.2 Wetland Delineation A Tighe & Bond wetland scientist conducted a site visit and field delineation of jurisdictional wetland resource areas in April 2023. Resource areas identified include inland Bank and Bordering Vegetated Wetlands (BVW), on each side of the Nashawannuck Brook within 200-feet of the Dam. Wetland resource areas were delineated in accordance with the methodologies outlined in Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act (September, 2022), the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1 (January, 1987), the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and Northeast Region (January, 2012), and the City of Northampton Wetland Protection Ordinance (Chapter 337). Wetland resource area flags placed in the field were surveyed with a GPS unit with sub-meter accuracy and integrated iPad for data collection and documentation. The results of the wetland delineation are summarized in the wetland delineation report provided in Appendix B. In general, the Nashawannuck Brook bank widths ranged from 4 to 10 feet wide and were well-defined. Three small BVWs associated with the brook exist upstream of and bordering the impoundment. One larger BVW was identified southwest of the impoundment that was hydrologically connected to the brook via an intermittent stream channel that discharges to Nashawannuck Brook approximately 200 feet downstream of Nashawannuck Brook Dam. The delineated wetlands were in transitional Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-3 states (e.g. turf grass remained dominant vegetation, soils were mixed, etc.). Wetland status was confirmed by hydrology, vegetation, and soil characteristics at the sites. 2.2.3 Sediment Sampling and Due Diligence Review Tighe & Bond conducted an assessment of sediment depth in the impoundment along cross-sections spaced at approximately 25-foot intervals. Sediment depth was measured at regular intervals across each transect with a probing rod. At each measurement location, depth to the top of sediment was measured and recorded. The probing rod was then advanced by hand until refusal was encountered, and the depth was recorded, along with the nature of the refusal (i.e., soft refusal, hard bottom refusal). Each sediment depth profile location was collected with a GPS unit with sub-meter accuracy. Tighe & Bond conducted a limited environmental due diligence review of publicly available records associated with the Project area and the general surrounding area. This review was performed to determine the potential for the sediment within the impoundment to have elevated concentrations of oil or hazardous materials (OHM), as defined in the Massachusetts Contingency Plan (MCP) 310 CMR 40.0000. A search of available Federal and State environmental records was obtained from Environmental Data Resources, Inc. (EDR). Tighe & Bond reviewed relevant files for select properties located within 1.0 mile of the Project area. Relevant files were reviewed on the Massachusetts Energy & Environmental Affairs (EEA) Data Portal search page for Waste Site & Reportable Releases1. Tighe & Bond’s due diligence review included a summary of existing information and reports provided by the project partners including the 2019 Phase I Environmental Site Assessment Report prepared by O’Reilly, Talbot & Okun Engineering Associates. The releases identified are unlikely to have impacted the impoundment since they are located downstream or outside the drainage area and are therefore likely not hydrologically connected by surface water or groundwater. Based on the locations of the properties and/or the regulatory status of the releases, the releases at these properties do not appear likely to have impacted the Project Area. In advance of dam removal activities and support of the 401 Water Quality Certification (WQC) permitting process, MassDEP requires that a project-specific Sampling and Analysis Plan (SAP) be submitted for review and approval. Tighe & Bond prepared an SAP for submittal to MassDEP using information obtained through the due-diligence review that was approved by MassDEP by email on April 18, 2023. As part of the sediment characterization effort, Tighe & Bond estimated the volume of soft sediment within the impoundment. Sediment thickness was measured at 20 locations distributed across the impoundment, using a graduated fiberglass probing rod. At each location, the probing rod was lowered over the side of a boat until resting on the top of sediment, and a depth to bottom measurement was recorded. The probing rod was then advanced through the soft sediment until refusal was encountered. The depth to refusal measurement was recorded, along with the type of refusal (i.e., soft or hard refusal), yielding a sediment thickness measurement. The sediment probing performed as part of the survey found accumulated sediment above the Nashawannuck Dam impoundment’s 1 https://eeaonline.eea.state.ma.us/portal#!/search/wastesite Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-4 hard bottom to be up to 2.6 feet thick, with a total estimated volume of soft sediment of approximately 550 cubic yards. To establish an understanding of sediment quality throughout the project area, a total of four composite sediment samples were collected on April 27, 2023. Each composite sediment sample was prepared from three aliquots (grab samples). The sediment sample locations are described below:  Two composite samples were collected from the accumulated sediment profile within the Nashawannuck Dam impoundment. The locations were selected to provide an overview of sediment in the impoundment.  One composite sample was collected from upstream of the Nashawannuck Dam impoundment to evaluate background conditions and contributing sources of sediment.  One composite sample was collected from the depositional area at the downstream limits of the property to evaluate downstream sediment quality. Each aliquot was collected using hand tools and placed into a stainless-steel bowl for general characterization and sample preparation. Following collection and preparation, each composite sample was placed directly into laboratory-supplied containers. Samples submitted to the laboratory for volatile organic compound (VOC) analysis were collected from an individual aliquot, prior to preparation of the final composite sediment sample, and determined based on the highest total organic vapor (TOV) reading, using a photoionization detector (PID), however, no detectable TOVs were detected from the samples, so the VOC samples were collected from the “middle” aliquot of each composite sample. Contaminant concentrations detected in sediment samples collected from the brook and impoundment are indicative of good overall sediment quality. The few contaminants that were detected above laboratory reporting limits are generally present in similar concentrations upstream and downstream of the impoundment, with no significant difference variations in contaminant concentrations noted.

Appendix D is a Sediment Management Plan prepared by Tighe & Bond. 2.3 Hydrologic & Hydraulic Analysis Tighe & Bond performed a hydrologic and hydraulic analysis to evaluate existing hydraulic conditions of Nashawannuck Brook Dam and to evaluate dam removal alternatives. Tighe & Bond evaluated existing conditions and two removal scenarios as part of this study: 1. A “full” dam removal removing the entire dam embankment 2. A “partial” dam removal where some of the dam embankment remains in place (multiple “partial” dam removal alternatives were considered) 3. No action (existing conditions) Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-5 A summary of the evaluation is provided below, and the full methodology and results of the analysis are described in the Hydrologic and Hydraulic Analysis memorandum included as Appendix E of this report. 2.3.1 Methodology Model Development DER provided Tighe & Bond with the Nashawannuck Brook hydrologic and hydraulic model prepared by GZA, described in the Memorandum – Hydrologic and Hydraulic Models for Restoration Scenarios Nashawannuck Brook Restoration Project, Northampton, Massachusetts dated June 1, 2022. The model was prepared using the U.S. Army Corps of Engineers HEC-RAS modeling software, utilizing two-dimensional model components including direct rainfall and infiltration based on a Curve Number estimated by GZA. Tighe & Bond first verified the model results matched previously reported values and then made the following updates:  Updates to the existing conditions model: o Incorporated topographic survey from 3D laser scanning described in Section 2.2.1. o Added detail to Nashawannuck Brook Dam geometry “storage area 2D connections” based on survey. o Added the climate change rainfall depth with rainfall input based on the Resilient MA Action Team (RMAT) tool available from the Massachusetts Office of Energy and Environmental Affairs (EEA). The climate change scenario is described in more detail in Section 2.3.2.  Additional changes to create the “full” dam removal model scenario: o Deleted the two “storage area 2D connections” originally used to represent the dam drop inlet structure and dam crest. o Added pond bathymetry based on field measurements collected by Tighe & Bond. o Modified the elevation terrain at the dam to match proposed dam removal AutoCAD drawings. o Added a “proposed/anticipated” stream channel with geometry developed based on regression equations information from the USGS Streamstats. o Modified the manning’s n so that the proposed stream had a manning’s n of 0.03 and the “former pond” areas outside the anticipated stream had a manning’s n of 0.1 assuming wetland vegetation develops.  Additional changes to create the “partial” dam removal model scenario: o Added a “storage area 2D connection” to “block” a portion of the fully removed dam to create the partially removed scenario. Proposed Conditions Development The channel width corresponding to bankfull or “channel forming” flow is referred to as the bankfull width, with higher flow entering the floodplain where velocities tend to be lower. The existing channel at the site was constructed for the golf course so an accurate Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-6 estimate of natural bankfull width was not possible using field indicators; therefore, Tighe & Bond estimated a bankfull width and bankfull depth using regression estimates of 10 feet and 1 foot, respectively. Typically a low flow channel exists within the bankfull channel that is typically inundated. Tighe & Bond estimated a low flow geometry using manning’s equation with a median flow of 0.3 cubic feet per second available from regression equations (Ries, K.G., III, 20002). Figure 2-1 shows the anticipated/approximate geometry used for modeling. FIGURE 2-1 Summary of Low Flow Channel For both proposed scenarios Tighe & Bond assumed the bankfull channel at the former dam embankment transitions into an inset floodplain “bench” on either side with varying width that transition into 4 horizontal units per one vertical unit (4H:1V) side slopes that extend to the existing grade at the dam abutments (for full removal) and embankment (for the partial removal). The “full” dam removal is anticipated to have a 75-foot wide inset floodplain (total width including bankfull channel of 85 feet) and the partial dam removal is proposed to have a 10-foot wide inset floodplain (total width including bankfull channel of 20 feet). 2.3.2 Climate Change Scenario Tighe & Bond evaluated a “climate change” rainfall event for each scenario using the methodology recommend by the Resilient MA Action Team (RMAT) Climate Resilience Design Standards Tool in accordance with the Massachusetts Environmental Policy Act (MEPA) Interim Protocol on Climate Change Adaptation and Resiliency. Based on the RMAT tool output a “Tier 1” precipitation approach is recommended using 0.9 times the 90th percentile precipitation flow depth from NOAA Atlas 14 input directly into HEC-RAS. A SCS Type III rainfall distribution was used in HEC-RAS consistent with the existing model runs. Note that the 25-year frequency storm event in 2030 is anticipated to exceed the current NOAA Atlas 14 50-year frequency storm event. The RMAT printout is included as Attachment B of the Hydrologic and Hydraulic Memorandum (Appendix D). 2 Ries, K.G., III,2000, Methods for estimating low-flow statistics for Massachusetts streams: U.S. Geological Survey Water Resources Investigations Report 00-4135, 81 p. (http://pubs.usgs.gov/wri/wri004135) Section 2 Data Collection and Analysis Tighe&Bond Nashawannuck Brook Basis of Design Report 2-7 2.3.3 Results The results of the analysis are described in the Hydrologic and Hydraulic Analysis memorandum included as Appendix D of this report. Table 2-1 provides a summary of anticipated water surface elevations upstream of dam for the evaluated alternatives, Table 2-2 provides a summary of the modeled height of water upstream of the dam, and Table 2-3 provides a summary of flow rates leaving the site. A summary of results related to the basis of design is provided below:  A full removal or partial removal would significantly reduce water levels upstream of the dam while causing inconsequential changes to downstream flow. o Both scenarios would result in a water surface elevation reduction of at least eight (8) feet for the evaluated storm events, with a greater reduction anticipated if a full removal is performed. o The peak outflow during the 100-year frequency storm event is anticipated to decrease following dam removal for both partial and full dam removal. The peak flows increase by less than 3 cfs and generally less than 3-percent for the dam removal scenarios compared to existing conditions for storm events less than the 100-year frequency storm event.  The existing dam is anticipated to pass a 10-year storm event without overtopping but overtop during a 50-year storm event. o Water levels for both proposed removal alternatives would not reach the former embankment elevation during the 100-year storm event.  The evaluated full dam removal and partial dam removal are considered feasible hydraulically and are anticipated to provide ecological improvements. o The minimum recommended channel bottom removal width for a partial removal is a 10-foot wide bankfull channel with 10-feet of inset floodplain (20 feet total). o An approximately 10-foot wide bankfull channel is proposed with inset floodplains for both dam removal alternatives.  A climate change scenario was evaluated that will meet the requirements of MEPA.  The full removal provides a greater reduction in water levels versus a partial removal and therefore is considered the preferred hydraulic alterative. Dam removals typically increase flows for more frequent storm events but can maintain or reduce flows during larger less frequent storm events. Both dam removal alternatives resulted in a slight reduction of 100-year frequency storm event peak flows decreased slightly, while less frequent events generally saw an increase in peak flow. Note modeling excluded rootwads and woody debris so additional reductions in flow may be anticipated. Other future anticipated stream restoration work (including constructing woody debris and adding sinuosity) are anticipated to reduce peak flows due to lengthening the stream channel and increasing roughness.

FEMA does not compute base flood elevations within Zone A areas and FEMA does not have models available for this area so the developed models are used to determine Bordering Lands Subject to Flooding (BLSF). Tighe&Bond Nashawannuck Brook Basis of Design Report 3-1 Section 3 Alternatives Evaluated 3.1 Alternatives Evaluated Tighe & Bond evaluated the following three removal alternatives as part of the feasibility study:  A “full” dam removal with remove of the entire dam embankment  A “partial” dam removal with a bankfull width breach where some of the dam embankment remains in place  No action 3.1.1 Full Removal of the Nashawannuck Dam The full dam removal alternative assumes a 10-foot wide bankfull channel (described in Section 2.3.1) that transitions into an inset floodplain “bench” on either side with varying width that transition into approximately 4H:1V side slopes that extend to the existing grade at the dam abutments. The full dam removal is anticipated to have a 75-foot wide inset floodplain (total width including bankfull channel of 85 feet). This alternative is anticipated to leave no visible embankment in the area of the dam and instead have gentle slopes tying into a wider than typical stream corridor. 3.1.2 Partial Removal of the Nashwannuck Dam Similar to the full dam removal alternative, the partial dam removal alternative assumes a 10-foot wide bankfull channel(described in Section 2.3.1) that transitions into an inset floodplain “bench” on either side with varying width that transition into 4H:1V side slopes that extend to the embankment. The partial dam removal is proposed to have a 10-foot wide inset floodplain (total width including bankfull channel of 20 feet). This alternative is anticipated to leave a visible embankment in place although once vegetated it may not be noticeable from all sides. 3.1.3 No Action (existing conditions) The No Action alternative would leave Nashawannuck Brook Dam in place, leaving the site as it is now. 3.2 Feasibility Tighe & Bond evaluated the feasibility of the three alternatives discussed above. The discussion of feasibility is split into the following categories for each alternative: 1. Hydraulics 2. Sediment 3. Constructability 4. Resource Impacts & Permitting 5. Benefits Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-2 6. Drawbacks 7. Conclusion Tighe & Bond also evaluated the following design aspects as part of both proposed dam removal alternatives:  Sediment management  Whether to construct a threshold channel, perform no stream stabilization, or perform limited strategic stabilization  Whether to relocate a portion of the stream to the existing gravel armored channel versus flowing into a more gently-sloping and meandering low lying area that may be the historical stream channel that flows back into the existing channel approximately 200 feet downstream of the dam  Whether or not to fill the former channel with embankment fill if the downstream channel is relocated  Site construction access 3.2.1 Full Removal of the Nashawannuck Brook Dam Hydraulics – Full removal of Nashawannuck Brook Dam would significantly reduce water levels upstream of the dam while causing inconsequential changes to downstream flow. Full removal would reduce upstream water levels more than partial removal. Sediment – The removal of the Nashawannuck Brook Dam would require management of sediment currently located upstream of the dam. In Tighe & Bond’s opinion, the levels of chemical constituents in sediment samples from Nashawannuck Brook Dam are low and not likely to cause significant ecological or human health risks. The results of the sediment management plan for the removal of the Nashawannuck Brook Dam is provided in Section 4.2 below. Resource Impacts and Permitting – The primary resource impacts caused by full removal of the Nashawannuck Brook Dam is the change of land under water to bordering vegetated wetlands and/or floodplain, which is an ecological benefit typical for dam removal projects. The following permits are anticipated:  Notice of Ecological Restoration Project to the Massachusetts Environmental Policy Act (MEPA) if full Ecological Restoration Project criteria are met (note advanced notification to Environmental Justice communities anticipated to be required).  401 Water Quality Certification pursuant to 314 CMR 9.00.  Section 106 Massachusetts Historical Commission Project Notification Form (PNF); Tribal Historic Preservation Officers, and the Massachusetts Board of Underwater Archeological Resources will also be copied on the submittal.  Pre-Construction Notification to the U.S. Army Corps of Engineers (USACE) under the Massachusetts General Permits (MA GP) for authorization as a restoration project (Section 404 of the Clean Water Act Authorization).  Restoration Order of Conditions from the Northampton Conservation Commission pursuant to the Massachusetts Wetlands Protection Act and the City of Northampton Wetlands Protection Ordinance. Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-3  City of Northampton stormwater management permit. Constructability – Dam removals inherently involve construction complications that include work in/adjacent to water, managing sediment, and stabilizing banks at and upstream of the removed/breached dams. Excess embankment material will need to be shipped offsite or reused onsite. Benefits – The primary benefits of removing Nashawannuck Brook Dam are restoring the brook to a more natural ecological state and improving ecological habitat (e.g., the creation of BVW in the former pond) by removing a barrier within Nashawannuck Brook. Removing the dam will also improve wildlife passage through Nashawannuck Brook while reducing the downstream peak 100-year peak flow. A secondary benefit is that the downstream sediment starved reach would be anticipated to receive natural sediment transport over time. The proposed design includes rerouting Nashawannuck Brook toward an apparent historic channel versus the constructed straight channel, again providing more natural stream processes to occur. Drawbacks – The proposed dam removal will result in excess soil from the former dam embankment that would need to be relocated onsite or disposed of off-site, and the full dam removal results in more excavated material than the partial dam removal (approximately 1,300 CY versus approximately 900 CY). While parts of the former pond are anticipated to transform into a BVW over time, it is possible that portions of the existing BVW located northwest of the pond may transition into more upland areas. Conclusion – In Tighe & Bond’s opinion, a full removal of Nashawannuck Brook Dam is feasible and will bring benefits to the City without adverse downstream impacts related to changes to peak flow leaving the site and will provide sediment for a previously sediment starved stream reach. This is considered the preferred alternative. 3.2.2 Partial Removal of the Nashawannuck Dam Hydraulics – Partial removal of Nashawannuck Brook Dam would significantly reduce water levels upstream of the dam while causing inconsequential changes to downstream flow. Partial removal would reduce water levels slightly less than full removal. Sediment – The same considerations as full dam removal. Resource Impacts and Permitting – The anticipated resource impacts and permitting are similar to the full dam removal; however, the MEPA requirements may vary since the project may be a Limited Ecological Restoration. Partial removals can also be permitted as full Ecological Restoration projects, and if the partial removal could be permitted as a full Ecological Restoration project the MEPA permitting would also match the full restoration alternative, otherwise:  Expanded Environmental Notification Form (EENF) pursuant to the Massachusetts Environmental Policy Act (MEPA) and Environmental Impact Report (EIR) waiver request (note advanced notification to Environmental Justice communities anticipated to be required) Constructability – The same considerations as full removal, although less embankment material would need to be managed. Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-4 Benefits – The same considerations as full removal, although less excess embankment material would be generated (approximately 900 CY versus approximately 1,300 CY). Drawbacks – The same considerations as full removal; however, there would be slightly less connectivity due to a portion of the embankment remaining. Conclusion – In Tighe & Bonds opinion, a partial removal of Nashawannuck Brook Dam is feasible and would bring benefits to the City without adverse downstream impacts related to changes to peak flow leaving the site and providing sediment for a previously sediment starved stream reach; however, benefits would be slightly less than full removal. This is not considered the preferred alternative. 3.2.3 No Action (existing conditions) Hydraulics – If no action is taken Nashawannuck Brook dam would continue to impound water during normal flow conditions and storm events. Sediment – Sediment would continue to collect over time if the dam is left in place, and the downstream reach would remain “sediment starved”. Resource Impacts and Permitting – If Nashawannuck Brook dam is left in place no permitting would be required as part of a dam removal effort; however, numerous permits are still anticipated to be required for other restoration activities planned by the project partners elsewhere onsite. Constructability – Not applicable, no construction proposed for this alternative. Benefits – Leaving Nashawannuck Brook Dam in place would be the least expensive approach. Drawbacks – Leaving the existing dam in place would not meet the project partner goals of restoring Nashwannuck Brook to a more natural ecological state or improving ecological habitat. Erosion is currently occurring along a gravel path located on the dam downstream slope, shown on Photo 3-1, that is likely negatively impacting downstream areas that are transitioning to wetland. If the dam is left in place the erosion and negative impacts are anticipated to continue. In addition, if the dam were to fail unexpectedly, there could be adverse downstream impacts. Dam maintenance (and associated costs) would be required to safely maintain the dam. Conclusion – In Tighe & Bonds opinion, leaving Nashawannuck Brook Dam in place is not recommended since the dam does not currently provide a useful function and removing the dam would restore the brook to a more natural ecological state and would improve ecological habitat. Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-5 Photo 3-1: Erosion of gravel path on downstream side of dam flowing into area that appears to be transitioning into a wetland 3.2.4 Sediment Management In general, there are three approaches to manage sediment as part of a dam removal: 1. Natural release (allowing clean sediment to travel downstream) 2. Mechanical removal (moving sediment with an excavator and reusing or disposing. 3. A mix of item 1 and item 2 above. Tighe & Bond evaluated the preferred approach in the sediment management plan provided as Appendix D. The results of the sediment characterization program were evaluated to identify appropriate sediment management approaches to support construction. Based on the characterization efforts described herein, potential materials management options are presented below. The City of Northampton is the property owner and considered the Generator of any materials that are to be managed off site. Contaminant concentrations detected in sediment samples collected from the brook and impoundment are indicative of good overall sediment quality. The few contaminants that were detected above laboratory reporting limits are generally present in similar concentrations upstream and downstream of the impoundment, with no significant difference variations in contaminant concentrations noted. As such, in Tighe & Bond’s opinion, there is flexibility in options for management of the sediment. The sediment characterization results indicate that the sediments from the project area are considered unregulated and are suitable for on-site reuse, including Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-6 disposal/management in an upland environment, or managed off-site. The sediments would also be suitable for passive instream management. The sediment can therefore be managed by natural (i.e., downstream migration) and mechanical (i.e., removing form site and either using for beneficial reuse or as fill at an ACO facility) methods, but natural processes are assumed. Instream management is anticipated during and following the dam removal wherein the Brook will reform within the former pond bottom within limits imposed by control points selected by the design team and approved by permitting agencies. Based on the sediment quality natural release is considered the preferred alternative for this study. 3.2.5 Channel Planform For dam removal projects there are three general approaches for establishing the stream upstream of a dam: 1. Perform no work in the impoundment, instead letting the stream form on its own once the dam is removed. 2. Design a threshold channel (i.e., one that is designed to stay in place) based on a reference reach. 3. Place strategic measures to set some limits to channel migration. For this study the project partners concluded that a threshold channel was not desired and that a softer approach was preferred; however, based on existing grade it is likely that a “straight line” channel may develop in the impoundment if no controls are placed. Using strategic controls was determined to be the preferred approach, with a mix of rootwads and rootwads with boulder infill used strategically promote Nashawannuck Brook meandering. 3.2.6 Channel Location Feasibility Nashawannuck Brook Dam currently discharges to a straight manmade channel with boulder banks and channel bottom consisting of angular gravel “ballast”. Photo 3-2 shows the downstream channel, and Photo 3-3 shows the downstream channel during low flow conditions. During the site evaluation a low lying area was identified to the east of the existing channel that appeared to be a historic channel and currently consists of primarily Land Under Water and some Bordering Vegetated Wetlands. Based on site conditions two alternatives were considered for the downstream channel: 1. Designing a dam breach so that Nashawannuck Brook flows into the existing anthropogenic downstream channel. 2. Designing a dam breach so that Nashawannuck Brook flows into the existing low lying area with more natural meanders that ties into the existing channel approximately 200 feet downstream of the dam. Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-7 Photo 3-2: Anthropogenic channel downstream of dam consisting of boulder banks and angular “ballast” gravel channel bottom Photo 3-3: Anthropogenic channel downstream of dam consisting of boulder banks and angular “ballast” gravel channel bottom during “low flow” period Designing a breach to flow into the existing channel would be easier to design than relocating the channel and may be less costly in the short term than relocating the stream. Relocating the stream is anticipated to allow it to develop a more natural planform than the armored boulder bank angular bottom channel. The project partners intend to “naturalize” the stream channel in the property in the future, so relocating the channel as Section 3 Concept Design Tighe&Bond Nashawannuck Brook Basis of Design Report 3-8 part of initial design phases (where convenient) was considered the preferred solution based on the long-term goals of the site. The riprap located at the existing channel banks could also be removed as part of the project and used as part of the site stabilization in the dam impoundment. 3.2.7 Filling Former Channel Feasibility If Nashawannuck Brook is moved away from the anthropogenic channel there are several options for what to do with the existing channel (once the riprap and gravel that can be reused onsite are removed): 1. Leave the former channel in its current condition. 2. Use embankment fill to fill the channel and adjacent areas. 3. Use some excess embankment cut material to fill the former channel and some adjacent areas while protecting existing trees to the extent possible. Tighe & Bond and the project partners were concerned that if the former channel was left in place Nashawannuck Brook would likely move back to the anthropogenic channel after the first bankfull storm event. Filling the channel was preferred; however, Tighe & Bond determined that using all the excess embankment fill in this location would likely significantly impact the downstream landscape including impacts to many trees. The preferred alterative was to use some excess embankment cut material to fill the downstream channel and regrade adjacent areas while leaving more healthy trees in place. Maintaining more “cut” than “fill” is also anticipated to provide compensatory storage requirements. 3.2.8 Site Construction Access Nashawannuck Brook Dam is not easily accessible for construction equipment from Old Wilson Road, and the two most likely access paths are: 1. Following the existing path system starting at the Old Wilson Road trailhead kiosk that goes over two existing culvert/bridges and an area of the path that appears to be transitioning into a wetland. 2. Creating a “Straight” access road from Old Wilson Road through upland grass area (with timber mats) and an existing path. During multiple site visits it was determined that much of the former grass areas onsite have started transitioning into wetlands, particularly areas near Nashawannuck Brook. Using the existing trail network from the Kiosk at Old Wilson Road was determined to be infeasible for a pickup truck as part of this feasibility study based on wet/moist areas. Construction equipment coming from this direction would also have to drive over several culvert stream crossings that are likely not designed to support construction equipment. A straight access path from Old Wilson Road toward an existing gravel trail northwest of the dam is considered the preferred alternative. The proposed access path is shown in C-102 Construction Access Plan of the preliminary design drawings for the Nashawannuck Brook Dam Removal provided as Appendix F. Tighe&Bond 4-1 Section 4 Preliminary Design The full dam removal alternative was selected as the preferred alterative based on the feasibility evaluation and coordination with the project partners, with slightly milder slope grades to provide a more varied and natural looking landscape. Tighe & Bond developed preliminary (40-percent) design drawing that are considered a sufficient level of detail for MEPA review. 4.1 Proposed Preliminary Design The preliminary design drawings for the Nashawannuck Brook Dam Removal are provided as Appendix F. The design includes:  Removing the majority of the existing embankment with 4H:1V slopes on the western side of the former embankment and with slopes less than 4H:1V on the eastern side to promote public accessibility and to provide a more varied landscape. The proposed channel would redirect flow into a natural low lying area.  Creating a starter channel and using rootwads, rootwads with boulder infill, and log riffles to set controls on stream migration. It is anticipated that the boulders and some of the rootwads would be obtained onsite.  Removing and making available for reuse angular gravel from downstream channel.  Removing and reusing rounded riprap boulders from the downstream channel.  Placing excess embankment material within existing downstream channel and adjacent areas to create smooth grades in the area while attempting to reduce impacts to healthy trees. 4.2 Sediment Management Plan A sediment management plan is provided as Appendix D and sediment management considerations are discussed in Section 3.2.4. For the purposes of the preliminary design approximately 200 to 300 cubic yards of sediment is assumed to transport downstream via natural release, and no sediment is assumed to be removed by mechanical removal. 4.3 Soil Management Strategy The Nashawannuck Brook dam removal is anticipated to result in a net “cut” of material due to the removal of the dam embankment. Some of the embankment soil can be placed in the area of the existing downstream channel that is being abandoned. A summary of approximate soil volumes for the proposed dam removal is provided below:  1,900 cubic yards of embankment and hard bottom “cut”  600 cubic yards of the cut can be used as fill downstream of the dam  1,300 cubic yards of excess soil anticipated to require reuse or disposal Excess embankment soil could be reused elsewhere onsite, removed and disposed offsite, or removed and reused elsewhere. Section 4 Preliminary Design Tighe&Bond 4-2 4.4 RMAT Resiliency Tool Tighe & Bond evaluated a “climate change” rainfall event for each scenario using the methodology recommend by the Resilient MA Action Team (RMAT) Climate Resilience Design Standards Tool in accordance with the MEPA Interim Protocol on Climate Change Adaptation and Resiliency and incorporated the results in the preliminary design. Detail on the methodology is described in Section 2.3.2 and the RMAT printout is included as Attachment B of the Hydrologic and Hydraulic Memorandum (Appendix D). 4.5 Anticipated Required Permits 4.5.1 Massachusetts Wetlands Protection Act (MAWPA) The MAWPA is administered by the City of Northampton Conservation Commission. The MAWPA establishes jurisdiction over work in and near wetland resource areas including inland Bank, Land Under Water Bodies and Waterways, Bordering Vegetated Wetlands (BVW), Bordering Land Subject to Flooding (BLSF; i.e., the limits of 100-year flooding), and the 200-foot Riverfront Area of perennial streams. The MAWPA regulations establish performance standards for each resource area, including minimum mitigation requirements. Note the reach of Nashawannuck Brook at the dam is not listed as a perennial stream so there is no 200-foot Riverfront Area. The Conservation Commission reviews permit applications, typically Notices of Intent (NOI), for compliance with resource area performance standards set forth in the MAWPA implementing regulations (310 CMR 10.00). The permit application process entails publishing a public notice in the local newspaper, notification of project abutters, and review by the Conservation Commission during one or more public hearings. Applications to the Conservation Commission are concurrently reviewed by the Massachusetts Department of Environmental Protection (MassDEP). The Conservation Commission may also choose to conduct a site visit to the project area. Upon completion of their review, the Conservation Commission votes to approve or deny the project. Approval of the project results in the issuance of a permit (Order of Conditions) that is subsequently recorded at the Registry of Deeds and is valid for a period of three (3) years. Activities that occur within the 100-foot Buffer Zone are also subject to Conservation Commission review per the MAWPA and, under certain circumstances, can be reviewed under a Request for Determination of Applicability (RDA). The RDA review process is similar to that of an NOI, though abutters are not notified and the Determination is not recorded. It is anticipated that the proposed dam removal activities would quality under the MAWPA as an Ecological Restoration project, as set forth at 310 CMR 10.24(8), resulting in the issuance of an Ecological Restoration Order of Conditions. Issuance of this permit would waive the need for a Wildlife Habitat Evaluation, allow the conversion or loss of a resource area without need for mitigation, and other allowances typically restricted by provisions of the MAWPA. Should the project scope increase to include activities across the property as a whole, the project may or may not meet the eligibility criteria for Ecological Restoration and may either be submitted as an Ecological Restoration Limited Project or a non- Ecological Restoration NOI. 4.5.2 Clean Water Act Vegetated wetlands and Land Under Water are further subject to protection and jurisdiction under Sections 401 and 404 of the Clean Water Act as “wetlands and Waters Section 4 Preliminary Design Tighe&Bond 4-3 of the United States.” Sections 401 and 404 are administered by MassDEP and the United States Army Corps of Engineers, respectively.  Section 401 –Generally, if the proposed activities within Waters of the US totals less than 5,000 square feet (temporary and/or permanent) and/or result in the cumulative dredge (including excavation and redeposit) of less than 100 cubic yards (from LUW only), then it is likely the MAWPA Order of Conditions can serve as the 401 Water Quality Certificate. Alterations greater than these thresholds typically require an Individual Water Quality Certificate.  Section 404 – This program is administered by the United States Army Corps of Engineers (Corps) under the General Permits for the Commonwealth of Massachusetts (MA GPs). With similar thresholds to Section 401, the MA GPs establish thresholds and conditions for work in Waters of the US that include, but are not limited to, time of year restrictions relative to the use of in-water controls (e.g., coffer dams) and work resulting in tree removal that may impact Northern Long-Eared Bats or other federally protected species. It is anticipated that the proposed project will result in impacts of greater than 5,000 square feet within Waters of the US. Accordingly, it is expected that a 401 Water Quality Certificate and Pre-Construction Notification will be required for the proposed dam removal project. The same permit requirements would be expected if the project scope were expanded to include additional restoration/improvement activities onsite. Since state permits will be required for the proposed work it is anticipated that a Section 106 Massachusetts Historical Commission PNF will also be required. The PNF would be copied to the Tribal Historic Preservation Officers and the Massachusetts Board of Underwater Archeological Resources. 4.5.3 Massachusetts Environmental Policy Act (MEPA) The proposed Nashawannuck Brook Dam removal project is anticipated to trigger MEPA review impact threshold on its own and the larger restoration planned by the project partners may require MEPA review regardless of the dam removal. Removal of a non- jurisdictional dam does not trigger MEPA on its own (note removal of a jurisdictional dam would automatically trigger MEPA); however, approximately 35,000 square feet of permanent impact to non-BVW wetland areas (BLSF or land under water) are anticipated. The site appears to be within one mile of two Environmental Justice communities so outreach mandated by MEPA would also be required. MEPA recently updated their policies to require less stringent requirements for full Ecological Restoration projects; however, Ecological Restoration Limited projects are not included in the updated policy. The two anticipated possible MEPA pathways are:  If the project is considered an Ecological Restoration project a Notice of Ecological Restoration Project must be submitted to MEPA with advanced notification to Environmental Justice communities within one mile of the site.  If the project is considered an Ecological Restoration Limited project an Expanded Environmental Notification Form (EENF) pursuant to the MEPA and Environmental Impact Report (EIR) waiver request would be required. Section 4 Preliminary Design Tighe&Bond 4-4 4.5.4 City of Northampton Local Ordinances 4.5.4.1 Wetlands Protection Ordinance Work proposed within the Site may be subject to the City of Northampton Wetlands Protection Ordinance (Chapter 337) and its implementing regulations. Review under Chapter 337 would occur in conjunction with the MAWPA as described in Section 2.1 above. Work proposed within areas jurisdictional under Chapter 337 must meet the Performance Standards set forth at Chapter 337-10. These standards include requirements for wetland replication including a 2:1 replacement ratio of wetland area lost and transplanting of the top 12 inches of soil, as well as limitations for work within Buffer Zone. Due to the nature and size of proposed work Tighe & Bond recommends the City request a waiver for these requirements with the Conservation Commission agent. 4.5.4.2 Stormwater Management Ordinance Work proposed within the Site may additionally be subject to the City of Northampton Stormwater Management Ordinance (Chapter 281) and its implementing regulations. This local ordinance requires that a stormwater management permit be acquired for any construction activity, new development, or redevelopment that will disturb greater than one (1) acre of land in Northampton. Exempt activities are described in Northampton Stormwater Management Ordinance (Chapter 281) As set forth at Chapter 281-3(c), strict compliance with the Stormwater Management Ordinance may be waived if the project is:  Allowed by federal, state and, local statutes and/or regulations; and  In the public interest; and  Consistent with the purpose and intent of this chapter. 4.5.4.3 40-foot Bordering Lands Subject to Flooding Buffer The City of Northampton defines a 40-foot Bordering Lands Subject to Flooding (BLSF) buffer zone in the City of Northampton Wetlands Protection Ordinance (Chapter 337). The 40-foot BLSF buffer is shown on the drawings. 4.6 Anticipated Resource Area Impacts Tighe & Bond anticipates that the existing Land Under Water upstream of Nashawannuck Brook Dam will reduce from approximately 20,000 square feet to approximately 3,000 square feet with former Land Under Water areas expected to transition into BVW and floodplain. Approximately 2,000 square feet of Land Under Water downstream of the dam is anticipated to be permanently converted to upland, floodplain or BVW. The proposed work includes less than 50 feet of permanent impacts to BVW downstream of the dam where grading of the embankment and downstream fill tie into existing grade. Over time a portion of the BVW area within the former stream channel, located downstream of the proposed channel, is anticipated to covert to LUW. Assuming a 10-foot bankfull channel forms approximately 700 square feet of BVW is anticipated to convert to LUW over time, although additional BVW may form adjacent to the new LUW areas. Section 4 Preliminary Design Tighe&Bond 4-5 All proposed work (other than access) is within the 100-foot buffer zone and the Northampton 40-foot Bordering Lands Subject to Flooding (BLSF) buffer zone, and the majority of the proposed work is within existing BLSF. While fill is proposed within BLSF the amount of cut proposed onsite is much greater than the fill so it is anticipate the compensatory storage requirements would be met. The proposed work includes a total of approximately 35,000 square feet of non-BVW impacts (Land Under Water and BLSF). 4.7 Opinion of Probable Construction Cost (OPCC) Tighe & Bond prepared feasibility/preliminary level Opinions of Probable Construction Cost (OPCCs) for the alternative designs. The OPCCs are focused on the engineering aspects of the dam removals (e.g., grading, in-stream features, and removal of dam components) and exclude walking path, park features, and the anticipated bridge crossing Nashawannuck Brook Dam. Table 4-1 provides a feasibility/ preliminary level OPCC for the engineering portions for full removal of Nashawannuck Brook Dam and Table 4-2 provides an estimate for partial removal of Nashawannuck Brook Dam. Cost savings may result if the project is bid with other planned restoration work at the site. The estimated additional cost per linear foot of removed embankment (i.e., inset floodplain) beyond the minimum recommended is $8,500 per ten linear feet of breach width. The reason the additional cost is relatively low is that the additional earthwork effort is small compared to the overall construction cost.

Tighe&Bond Nashawannuck Brook Basis of Design Report 5-1 Section 5 Design Renderings Tighe & Bond developed a conceptual site plan and a perspective rendering graphic to visualize the future impoundment and embankment area following dam removal and to visualize potential trail network modifications and site amenities following dam removal. The conceptual site plan and perspective rendering are provided as Appendix G. The renderings include expanding the existing trail network to improve pedestrian access, a location for a potential pedestrian bridge cross to maintain access over Nashawannuck Brook onsite, and potential locations for two seating areas. The proposed dam removal along with trail improvements is anticipated to allow the public to view the ecological improvements of Nashawannuck Brook up-close. Tighe&Bond 6-1 Section 6 Conclusion and Next Steps Tighe & Bond performed a dam removal assessment for Nashawannuck Brook Dam and developed a preliminary design for dam removal. Based on review of available data, collected data, modeling, and conceptual design, Tighe & Bond believes the proposed preliminary design for full removal of Nashawannuck Brook Dam is feasible. Tighe & Bond anticipates the next steps to progress the design are:  Advance concepts for other site restoration work to support MEPA and then prepare and submit application to MEPA.  Perform wetland delineation along the proposed site access route.  Perform hydrogeomorphic calculations for in-stream wood features.  Progress the dam removal design from approximately 40-percent level to approximately 60-percent level for permitting through the U.S. Army Corps of Engineers and MassDEP.  Design bridge crossing and path network (currently only shown conceptually in the renderings).  Update hydrologic and hydraulic modeling to match 60-percent design and to include bridge crossing.  Prepare and submit required permit applications.

Figures illustrating the location of the Site are provided in Attachment 1 and representative photographs are provided in Attachment 2. This memorandum describes Tighe & Bond’s delineation and characterization of the existing wetland resource areas. Potential regulatory constraints relative to dam removal and/or other alterations of the subject parcels are discussed in the Basis of Design Memorandum. 1 Wetland Resource Area Investigation 1.1 Methodology of Wetland Resource Area Investigation On April 19, 2023, a Tighe & Bond wetland scientist visited the site to identify and delineate wetland resource areas and evaluate the jurisdictional status of each resource area relative to local, state, and federal criteria. Photos from the site visits are provided in Attachment 2. This wetland delineation was conducted in conformance with local, state, and federal guidelines, including the Massachusetts Handbook for Delineating Bordering Vegetated Wetlands (MassDEP, 2022), the 1987 Corps of Engineers Wetlands Delineation Manual, the Regional Supplement to the Corps of Engineers Wetlands Delineation Manual - Northcentral and Northeast Region (2012), Field Indicators for Identifying Hydric Soils in New England (Version 4, 2017), and the City of Northampton Wetlands Protection Ordinance (Chapter 337). Tighe & Bond also reviewed the most recent flood data available from the Federal Emergency Management Agency (FEMA) for the site and surrounding area. According to the City of Northampton Flood Insurance Rate Map (FIRM; Community-Panel No. 250167 0002A, effective date: April 3, 1978), the site is located within the limits of 100-year flooding, Zone A. Additionally, our review of the Massachusetts Natural Heritage and Endangered Species Program (NHESP) Atlas (15th edition published August 2021) confirmed that neither the Site nor surrounding area are mapped as either Priority Habitats of Rare Species or Estimated Habitats of Rare Wildlife. TECHNICAL MEMORANDUM Tighe&Bond -2- 1.2 Summary of Wetland Resource Areas The following wetland resource areas have been identified within the site, and are subject to jurisdiction under the Massachusetts Wetlands Protection Act (MAWPA; M.G.L. Chapter 131 §40), the City of Northampton Wetlands Protection Ordinance (Chapter 337), and the United States Army Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and Northeast Region (January 2012): • Inland Bank/Ordinary High Water • Bordering Vegetated Wetlands (BVW) • Bordering Land Subject to Flooding (BLSF) The proposed work will additionally take place within the 100-foot Buffer Zone to inland Bank and BVW as well as the local 40-foot Buffer Zone to BLSF. Vegetated wetlands and waterways are also subject to jurisdiction under the Clean Water Act. Refer to Section 2 of this memorandum for additional discussion of regulatory jurisdiction. Wetland resource areas within the Site, as well as their associated Buffer Zones, are shown on Figure 1 in Attachment 1. A summary of wetland resource areas delineated by flag series is presented in Table 1-1.

Cowardin, U.S. Fish and Wildlife Service, 1979 1.2.1 Inland Bank Bank is defined at 310 CMR 10.54(2)(c) as “the portion of the land surface which normally abuts and confines a water body. It occurs between a water body and a vegetated bordering wetland and adjacent flood plain, or, in the absence of these, it occurs between a water body and an upland.” This section provides a summary of inland Bank within the Project Site. 1A/1B Series - Nashawannuck Brook Nashawannuck Brook is mapped as intermittent on the most recent USGS topographic quadrangle (Easthampton, MA 2021). According to a USGS StreamStats analysis (included as Attachment 3), the Brook has a drainage area of 0.37 square miles. Per the MAWPA regulations set forth at 310 CMR 10.58(2)(a)(1)(c)(i), the stream does not meet the criteria to be considered perennial. TECHNICAL MEMORANDUM Tighe&Bond -3- Flag series 1A/1B defines the west and east banks (respectively) of Nashawannuck Brook upstream of the existing dam, while series 4A and 4B define the same banks downstream of the dam. The Brook has an unconsolidated cobble streambed and ranges from approximately 4 to 10 feet wide in the vicinity of the Project Site. The Banks of the brook are well defined, particularly immediately downstream of the dam where the channel is constrained by stones placed by previous landowners. Within this area, the brook flows through forested, emergent, and scrub shrub cover. Dominant vegetation along the Bank includes eastern hemlock (Tsuga canadensis; FACU), eastern white pine (Pinus strobus; FACU), Canada mayflower (Maianthemum canadense; FACU), yellow trout lily (Erythronium rostratum), and invasive Morrow’s honeysuckle (Lonicera morrowii; FACU). 2A Series The 2A flag series defines the Bank of the impoundment created by Nashawannuck Brook Dam. The impoundment is fed by the brook to the north and receives runoff from the surrounding upgradient area of the retired golf course. The bed of the impoundment is characterized by an organic substrate and gradually slopes from the Bank, becoming several feet deep as it approaches the center. The impoundment discharges to Nashawannuck Brook via a culvert that runs below the dam located at its southern extent. The Bank of the impoundment is well defined and sparsely vegetated by turf grasses and goldenrod (Solidago sp.). 3B/3C Series The 3B/3C flag series demarcates the south and north Banks of an intermittent stream not mapped on the most recent USGS topographic quadrangle. The stream is fed by BVW 3A from the northwest and discharges to Nashawannuck brook to the southeast. The channel width is variable, ranging from approximately 1 to 15 feet, and the Banks are generally poorly defined. The stream is characterized by a mud/organic bottom. Vegetation along the bank was dominated by eastern hemlock (T. canadensis), eastern white pine (P. strobus), and skunk cabbage (Symplocarpus foetidus; OBL). The stream channel was devoid of vegetation apart from one area where tussock sedge (Carex stricta; OBL) was observed. 1.2.2 Bordering Vegetated Wetlands Bordering Vegetated Wetlands (BVW) are defined at 310 CMR 10.55(2)(a) as “… freshwater wetlands which 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 ground and surface water regime and the vegetation community which occur in each type of freshwater wetland are specified in M.G.L. c 131 sec. 40.” BVWs identified in the vicinity of the Project Site are recorded in Army Corps of Engineers Wetland Determination Data Forms included as Attachment 4 and summarized below. 1C Series Flag series 1C defines the boundary of a small palustrine emergent (PEM2B) wetland bordering Nashawannuck Brook upstream of the existing dam and impoundment. The BVW is positioned on a slope and is fed by natural drainage from upgradient areas. Significant erosion into the stream channel was observed within the wetland. The depth of the water table varied within the BVW but was encountered within 2 inches of the surface at the wetland’s lowest extent near the stream channel. Vegetation within BVW 1C was dominated by soft rush (Juncus effusus; OBL), sensitive fern (Onoclea sensibilis; FACW), silky dogwood (Cornus amomum; FACW), gray birch (Betula populifolia; FAC), and turf grass. Soils in this wetland consisted of 8 inches of very dark greyish brown (10YR 3/2) loamy sand with light brownish TECHNICAL MEMORANDUM Tighe&Bond -4- grey (10YR 6/2) depletions. This layer was underlain by 6 inches of very dark greyish brown sandy loam with brownish yellow (10YR 6/8) concentrations. This soil profile meets the Stripped Matrix (S6) hydric soil indicator. 1D Series Flag series 1D demarcates a palustrine emergent (PEM2B) BVW associated with the northwestern Bank of the impoundment. The wetland is situated in a toeslope position and receives drainage from the surrounding area. BVW 1D is sparsely vegetated, but dominated by soft rush (J. effusus). The water table was encountered at 6 inches below the ground surface and soils were saturated to the surface. The soil profile within this BVW consisted of 4 inches of black (10YR 2/1) mucky sand underlain by 6 inches of brown (10YR 5/3) sand. This soil profile meets the criteria for the Sandy Mucky Mineral (S1) hydric soil indicator. 2C Series Flag series 2C demarcates a palustrine emergent (PEM2B) BVW associated with the western Bank of Nashawannuck Brook and the northeastern Bank of the impoundment. The wetland extends across a steep hillslope rising from the impoundment as well as the gently sloped terrace near the confluence of the Brook and impoundment. Subsurface discharge from the surrounding area was observed flowing down the eroded slope and standing water clouded with reduced iron was observed on the terrace. BVW 2C was dominated by cattail (Typha Sp.; OBL) and turf grass. Soils profiled within this wetland included 6 inches of black (10YR 2/1) mucky sand, meeting the criteria for the Sandy Mucky Mineral (S1) hydric soil indicator. 3A Series Flag series 3A defines the boundary of a mixed palustrine emergent and forested wetland (PEM2E/PFO1E) located to the west of Nashawannuck Brook downstream of the dam. The wetland is positioned on a toeslope and is fed by a culvert conveying upgradient drainage from the retired fairways. At its southern extent the wetland channelizes into an intermittent stream mapped as series 3B/3C (described above). Indicators of wetland hydrology included presence of surface water and water-stained leaves. Vegetation within BVW 3A was dominated by eastern hemlock (T. canadensis), eastern white pine (P. strobus), jewelweed (Impatiens capensis; FACW), and Morrow’s honeysuckle (L. morrowii). A representative soil profile within the wetland consisted of 6 inches of black (10YR 2/1) mucky sand with brownish yellow (10YR 6/8) concentrations and gray (10YR 5/1) depletions. Below, 8 inches of gray (10YR 5/1) clay loam with gray (10YR 6/1) depletions and yellowish red (5YR 4/6) concentrations was observed. This soil profile meets the criteria for the Depleted Below Dark Surface (A11), Sandy Mucky Mineral (S1), Sandy Redox (S5), and Depleted Matrix (F3) hydric soil indicators. 1.2.3 Bordering Land Subject to Flooding Bordering Land Subject to Flooding (BLSF) is defined at 310 CMR 10.57(2)(a) and (c) as “…an area with low, flat topography adjacent to and inundated by flood waters rising from creeks, rivers, streams, ponds or lakes. It extends from the banks of these waterways and water bodies; where a bordering vegetated wetland occurs, it extends from said wetland… The boundary of Bordering Land Subject to Flooding is the estimated maximum lateral extent of flood water which will theoretically result from the statistical 100-year frequency storm. Said boundary shall be that determined by reference to the most recently available flood profile TECHNICAL MEMORANDUM Tighe&Bond -5- data prepared for the community within which the work is proposed under the National Flood Insurance Program…” Tighe & Bond reviewed the FEMA Flood Insurance Rate Map (FIRM) Community-Panel No. 2501670002A (effective date April 3, 1978). No Flood Insurance Survey (FIS) is available for Nashawannuck Brook at the Project Site. Therefore, the base flood elevation (BFE) and limits of BLSF will be determined by a hydrology and hydraulics analysis performed by Tighe & Bond. A FIRMette showing boundaries of BLSF in the vicinity of the subject parcel is provided in Attachment 1 of this memorandum. 1.2.4 Buffer Zone Activities within the 100-foot Buffer Zone to Bank and BVW are regulated under the MAWPA at 310 CMR 10.02(2)(b) and under the Northampton Wetlands Protection Ordinance (Chapter 337). Chapter 337 additionally regulates a 40-foot Buffer Zone to the boundary of BLSF. Buffer Zone within the Project Site consists primarily of retired fairway. These areas are generally dominated by turf grass and other herbaceous vegetation with isolated forested zones and the land slopes down towards Nashawannuck Brook downstream of the impoundment and BVW 3A. A pedestrian foot path crosses the dam south of the impoundment and extends to the eastern and western boundaries of the Project Site.

Please find an updated Due Diligence and SAP attached as well as the updated “Site Plan B”. The exact locations will vary slightly based on where sediment is observed but we’ll target the areas shown. Please let us know if you approve of the updated Due Diligence and SAP.

One minor comment – would you be able to stretch out the SED-104 cores spacing a bit? See snip below, with moved core location examples shown in red. If the new proposed spacing messes up your plan of sampling both within the boulder lined channel and downstream of the boulder lined channel, or if the new locations extend off property, let me know. Looking to get the best representativeness over a larger area where sediment will eventually be deposited and accumulate.

A few minor questions/considerations: - For proposed sample SED-103 group at the southern portion of the Pond, can you move the western and eastern cores in that group a bit more towards their respective shorelines, maybe 10 ft each? If you think moving those core locations will not result in getting a representative sample, let me know. o Tighe & Bond revised Figure 4 of the SAP to the new “Figure 4A” to reflect the proposed shift in sample locations. - For the proposed downstream SED-104 sample, can you spread those cores to represent a longer area of the downstream section of the stream which may have sediment redeposited? Maybe for the sample to be representative of up to about 225 ft downstream of the dam? It looks like the stream is a pretty straight shot from the dam to approximately 225 ft downstream where there appears to be a curved section, followed by a more meandering route, then a pronounced turn to the south. Not sure how far downstream you anticipate the sediment to be transported and redeposited. If you do not think sediment will be redistributed further than the ~80 ft section represented by sample SED-104 as shown on Figure 4, let me know. o Based on a site visit and further coordination with DER we have updated the downstream sampling location further downstream, and spread them out more. The stream bed immediately downstream of the channel was observed to primarily consist of coarse gravel (visually more similar to railroad ballast than a natural stream channel) with boulder banks. Based on our observations/coordination with DER, we’ve moved the downstream sediment sample locations to an area where deposits of sediment were observed further downstream at the boulder lined channel, and downstream of the boulder lined channel, with locations shown on a new Figure 4B approximately 1,200 feet downstream of the dam. - Do you have a general idea on how the downstream sediment transport will look; has it been modeled at all? I understand you are in your early stages of design, but considering how small/narrow a stream, how little flow there is (I presume), and the volume you indicated which may be released downstream, I am wondering where the sediment will travel to and if the newly deposited sediment would adversely affect stream grades and hydraulics in the longer term. 5 o We anticipate some sediment may settle within the boulder lined channel on the property; however, we anticipate the majority will migrate toward the wider natural channel at the downstream end of the property that later flows into the Arcadia Wildlife Sanctuary. The more natural downstream areas have wider banks, substantial woody debris within the channel, and beaver dams are reportedly typically onsite. If natural release is considered viable based on analytical testing Tighe & Bond will include a discussion of anticipated transport volumes and qualitative anticipated deposit locations in the Sediment Management Plan. Note that we believe the downstream reach has been sediment starved due to the dam and armored channel. Please let me know what you think. If you agree to those minor exploration location edits, please revise the SAP and resubmit for our approval. Thank you, Kenneth N. Alepidis, P.G.

The SAP was developed in general accordance with the Massachusetts Department of Environmental Protection (MassDEP) 401 Water Quality Certification regulations, 314 CMR 9.00. The purpose of the sampling described in this plan is to collect sediment quality data to support a feasibility evaluation for removal of Nashawannuck Pond Dam, and the development of a Sediment Management Plan. Tighe & Bond, DER, and the City understand that additional sampling may be required during the final design and permitting stages of the dam removal project. This draft SAP is being submitted to MassDEP for review and comment prior to site sampling activities, currently scheduled for April 2023. For reference, a Site Location Map (Figure 1), a Massachusetts Bureau of Geographic Information (MassGIS) Priority Resource Map (Figure 2), an Orthophotograph (Figure 3) , a Site Plan showing proposed sediment sampling locations (Figure 4), and a Site Plan depicting reported releases and drainage area for the Pond (Figure 5) are provided in Appendix A. 1.1 Site Location and Background Nashawannuck Brook is an intermittent stream that flows through the 105-acre former Pine Grove Golf Course property in Northampton, Massachusetts which is owned by the City. The Brook bisects the former Pine Grove Golf Course, and eventually flows through Mass Audubon’s Arcadia Wildlife Sanctuary and into the Manhan River. The drainage area of Nashawannuck Brook is approximately 0.5 square miles at the point where the Brook exits the City-owned parcel. The former Pine Grove Golf Course property was significantly altered by the development of the golf course and associated support structures, leaving little of the natural landscape intact. The property is currently dominated by fallow upland fairways, some linear forest features, and assorted hard structures, including an unregulated dam forming an irrigation impoundment. The dam is located on Nashawannuck Brook near the center of the Project area. The earthen dam is approximately 150 feet long and 10 feet wide with an approximately 0.5- acre impoundment. The dam is non-jurisdictional and not recognized or evaluated by the Office of Dam Safety for condition or hazard class. Water flows out of the impoundment through an unmanaged water control structure that formerly housed boards for manipulating water level in the impoundment. The outlet of the dam is a deteriorated corrugated metal pipe. Current access to the dam is from a pedestrian trail network on former golf cart paths, approximately 0.3 miles from the trailhead kiosk at Old Wilson Road. As part of the Nashawannuck Brook Restoration Project, Tighe & Bond is evaluating the feasibility and impacts of dam removal on Nashawannuck Brook. This evaluation includes sediment sampling to characterize the sediment within the impoundment as well as Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 1-2 upstream and downstream of the impoundment. If the sediment quality is suitable, the preferred sediment management approach will be passive downstream release. While the proposed sediment sampling is being conducted primarily to support a feasibility evaluation, the data may also be used to support future 401 Water Quality Certification permitting efforts. Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 2-1 Section 2 Limited Due Diligence Review Tighe & Bond conducted a limited environmental due diligence review of publicly available records associated with the Project area and the general surrounding area. This review was performed to determine the potential for the sediment within the impoundment to have elevated concentrations of oil or hazardous materials (OHM), as defined in the Massachusetts Contingency Plan (MCP) 310 CMR 40.0000. A search of available Federal and State environmental records was obtained from Environmental Data Resources, Inc. (EDR). A copy of this report (the EDR Radius Map Report) is provided in Appendix B. The date of the most recent update by the regulatory agency maintaining each database is listed at the end of the EDR Radius Map Report. Those sites with adequate address information (geo-coded) are plotted on maps provided within the EDR Radius Map Report. Sites with minimal address information (orphan sites) are listed separately in the report. The orphan sites were reviewed to determine whether they were potentially located in close proximity to the Project area. Tighe & Bond reviewed relevant files for select properties located within 1.0 mile of the Project area. Relevant files were reviewed on the Massachusetts Energy & Environmental Affairs (EEA) Data Portal search page for Waste Site & Reportable Releases1. While it is not possible for Tighe & Bond to verify the accuracy and/or completeness of information contained in the EDR Radius Map report and the files reviewed, the use and reliance of this information is an accepted practice in the performance of environmental assessments and due diligence reviews. In addition to the EDR Radius Map Report, Tighe & Bond reviewed historical city directories, historical aerial photographs, and historical topographic maps obtained from EDR®, a stormwater outfall map obtained from the City of Northampton’s website2, and other reports provided by DER. 2.1 OHM Releases On March 2, 2023, a search of OHM use, State-listed waste sites, and reportable releases was performed to evaluate if reported releases of OHM within, or adjacent to, the Project area have the potential to impact the sediment quality. The relevant sites evaluated are summarized below. 1 https://eeaonline.eea.state.ma.us/portal#!/search/wastesite 2 https://northamptonma.gov/DocumentCenter/View/12887/Northampton-MS4-Map---Dec-2018?bidId= Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 2-2 Table 2.1 Summary of Relevant OHM Use and Reported Releases Location RTN Summary of Environmental Condition Allen & Sons Inc Easthampton Road Northampton, MA Approx 0.379 miles Northeast RTN 1-0000549 • Former P.

The releases are unlikely to have impacted the impoundment since they are located downstream or outside the drainage area and are therefore likely not hydrologically connected by surface water or groundwater. Based on the locations of the properties and/or the regulatory status of the releases described above, the releases at these properties do not appear likely to have impacted the Project Area. 2.2 Stormwater Mapping Based on Tighe & Bond’s review of the City of Northampton’s stormwater outfall map, there are no City-owned stormwater outfalls in the vicinity of the impoundment. A copy of the Stormwater Outfall Map is included in Appendix C. 2.3 Client Provided Reports 2.3.1 2019 Phase I Environmental Site Assessment Report prepared by O’Reilly, Talbot & Okun Engineering Associates In December 2019, O’Reilly, Talbot & Okun Engineering Associates (OTO) conducted an ASTM Phase I Environmental Site Assessment of the Pine Grove Golf Course Property. The purpose of the Phase I was to evaluate the site history and current conditions as well as to identify Recognized Environmental Concerns (RECs), Historical Recognized Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 2-5 Environmental Concerns (HRECs), and Controlled Recognized Environmental Concerns (CRECs). Based on USGS maps, historical aerials, and information from the City of Northampton based on discussions with the former golf course owners, the land at the property was used for pasture and cropland through the mid-1950’s, prior to the golf course first being developed in the 1960’s at the northern end of the site. The northern portion of the site has reportedly been cleared since at least the 1880’s based on USGS mapping. Between 1960 and 1970, the golf course was constructed incrementally from north to south and included an 18-hole course, irrigation pond (the dam impoundment), pump house, maintenance building/residence, and club house. The southern portion of the site was forested land prior to golf course development. OTO’s Phase I report excluded the property associated with the maintenance building/residence and club house as the land was reportedly being subdivided. According to OTO’s Phase I report, the pump house building3 was located to the south of the dam impoundment and contained an irrigation pump, an empty 275-gallon aboveground storage tank (AST) formerly used to store diesel fuel, and two batteries. The pump house floor was observed to be concrete with minor staining. The AST was observed to be in good condition with no staining under the AST. No other use or storage of OHM was documented the Phase I findings. OTO’s Phase I did not identify RECs, HRECs, or CRECs at the property. 3 Please note the pump house building was removed prior to the City acquiring the property. Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 3-1 Section 3 Sediment Sampling Plan 3.1 Sediment Volume The volume of sediment within the impoundment will be estimated as part of Tighe & Bond’s feasibility evaluation. In accordance with the 401 Water Quality Certification dredge material sampling and analysis requirements outlined at 314 CMR 9.07(2)(b), one sample core should be collected and characterized physically and chemically for every 1,000 cubic yards (c.y.) of proposed dredge material for projects up to 10,000 c.y., with a minimum of two samples collected. Two sediment samples will be collected from within the dam impoundment each representing a composite from three locations. Additionally, sediment samples will be collected upstream and downstream of the impoundment. Tighe & Bond will conduct an assessment of sediment depth in the impoundment along cross-sections spaced at approximately 25-foot intervals. Sediment depth will be measured at regular intervals across each transect with a probing rod. At each measurement location, depth to the top of sediment will be measured and recorded. The probing rod will then be advanced by hand until refusal is encountered, and the depth will be recorded, along with the nature of the refusal (i.e., soft refusal, hard bottom refusal). Each sediment depth profile location will be collected with a Global Positioning System (GPS) unit with achieve sub-meter accuracy. The sediment depth data will be used to compute the volume onsite; however, based on the area of the pond less than 2,000 c.y. of proposed dredge is anticipated. The sampling proposed in this SAP will be used to support an initial dam removal feasibility evaluation and the development of a Sediment Management Plan. While this data may also be used to support future 401 Water Quality Certification efforts, Tighe & Bond and DER understand that additional sampling may be required to comply with the requirements outlined at 314 CMR 9.07. 3.2 Sampling and Analysis To characterize the sediment within the impoundment as well as upstream and downstream of the impoundment, Tighe & Bond will collect up to 12 sediment cores/grab samples from the accumulated accessible sediment profile. Tighe & Bond anticipates three samples will be collected from the stream channel upstream of the dam, three will be taken from the stream channel downstream of the dam, and six will be taken within the impoundment. Sediment samples will be collected using either an AMS™ stainless steel core sampler and safety hammer or a ponar grab sampler. If used, the stainless-steel core sampler will be lined with dedicated polycarbonate core barrel liners to eliminate the potential for cross- contamination of sediment samples. Non-dedicated sampling tools (i.e., stainless-steel sampler, ponar sampler, and hand tools) will be decontaminated with an Alconox soap/water solution prior to use and between sample locations. During sampling, grab samples will be field screened via a photoionization detector (PID) for total volatile organic vapors (TVOVs). Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 3-2 The cores/grab samples will be combined in sets of three to prepare four composite samples to be submitted for laboratory analysis, as described in Section 3.2.1. At each sediment sample location, information on depth to sediment (water column), sediment thickness, and physical characteristics will be recorded. Each sample location will be documented in the field with a hand-held GPS unit. Proposed sediment sampling and probing locations are shown on Figure 4 in Appendix A. Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 3-3 3.2.1 Analytical Parameters Due diligence activities indicated that the Project area was developed as a golf course between the 1930’s and 1970’s. Chemicals including pesticides, herbicides, and fertilizers are commonly applied to golf courses and agricultural properties as part of normal operations. The application of these chemicals may result in their presence in soil, groundwater, and/or sediment over time. However, due to the widespread use in the area, these chemicals are expected in to be present in similar concentrations upstream, downstream, and within the impoundment. Although passive downstream release is the preferred sediment management approach, pesticides and herbicides is included in the SAP, since pesticides and herbicides data will likely be required to support upland reuse or off-site management of the sediment. An enclosed 275-gallon diesel AST was reportedly located within the pump house formerly located to the south of the impoundment. While there have been no reported or documented releases of diesel associated with the former AST, contaminants of concern associated with diesel include extractable petroleum hydrocarbons (EPHs) and polycyclic aromatic hydrocarbons (PAHs). Therefore, due diligence activities did not identify the need to supplement the required analytical parameters identified in MassDEP 401 Water Quality Certification Regulations, 314 CMR 9.07(2)(b)(6). It is anticipated that each sediment sample will be submitted to a National Environmental Laboratory Accreditation Conference (NELAC) accredited environmental laboratory for the following analyses: • Total Metals – Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, and Zinc; • EPHs with target PAHs; • Polychlorinated Biphenyls (PCBs) Congeners; • VOCs – Grab sample will be submitted from the portion of the core with the highest PID reading; • Total Organic Carbon (TOC); • Percent water; • Grain Size Analyses; • Pesticides include DDT, DDE, DDD, Aldrin, Endrin, Dieldrin; • Herbicides; and, • Toxicity Characteristic Leaching Procedure (TCLP), as applicable. The samples will be collected in laboratory-supplied containers with appropriate preservation (where applicable). Samples collected for analysis via EPA and MassDEP methods will be preserved in accordance with the method specifications. Samples will be stored in a cooler with ice or refrigerator and measured upon laboratory receipt at a temperature less than 6°C, transferred to the laboratory under chain-of-custody protocols, and analyzed within the appropriate holding times. Sufficiently sensitive analytical methods will be used to achieve the required reporting limits established in 314 CMR 9.07(2)(b)(6). In the event that one or more of the required Tighe&Bond Due Diligence Review and Sampling and Analysis Plan Nashawannuck Brook Restoration Project 3-4 reporting limits are not met, a discussion of the reasons for the inability to achieve the reporting limit will be included in the Sediment Management Plan. 3.1.2 Data Comparison Following the receipt of the laboratory report, the data will be tabulated and compared to the Reportable Concentrations, Method 1 Standards, and Method 2 Standards established in the MCP 310 CMR 40.0000 (RCS-1 Criteria, Method 1 S-1 Standards, and Method 2 S- 1, S-2, and S-3 Standards) and the Consensus-Based Sediment Quality Guidelines [Threshold Effects Concentrations (TECs) and Probable Effects Concentrations (PECs)] developed predominantly by MacDonald et al. (2000)4. MassDEP will be provided with a summary table and electronic copy of the analytical results. 4 MacDonald, D. D., C. G. Ingersoll, T. A. Berger. 2000.

The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

A PWS is any water system which provides water to at least 25 people for at least 60 days annually. PWSs provide water from wells, rivers and other sources. PWS ENF: Public Water Systems Violation and Enforcement Data Source: EPA/Office of Drinking Water Telephone: 202-564-3750 Violation and Enforcement data for Public Water Systems from the Safe Drinking Water Information System (SDWIS) after August 1995. Prior to August 1995, the data came from the Federal Reporting Data System (FRDS). USGS Water Wells: USGS National Water Inventory System (NWIS) This database contains descriptive information on sites where the USGS collects or has collected data on surface water and/or groundwater. The groundwater data includes information on wells, springs, and other sources of groundwater. STATE RECORDS Massachusetts Geographic Information System (MassGIS) Datalayers Source: Executive Office of Environmental Affairs Telephone: Public Water Supply Database Telephone: The Public Water Supply datalayer contains the locations of public community surface and groundwater supply sources and public non-community supply sources as defined in 310 CMR 22.00. Areas of Critical Environmental Concern Telephone: The Areas of Critical Environmental Concern (ACEC) datalayer shows the location of areas that have been designated ACECs by the Secretary of Environmental Affairs. ACEC designation requires greater environmental review of certain kinds of proposed development under state jurisdiction within the ACEC boundaries. The ACEC Program is administered by the Department of Environmental Management (DEM) on behalf of the Secretary of Environmental Affairs. The Massachusetts Coastal Zone Management (MCZM) Office managed the original Coastal ACEC Program from 1978 to 1993, and continues to play a key role in monitoring coastal ACECs. Procedures for ACEC designation and the general policies governing the effects of designation are contained in the ACEC regulations (301 CMR 12.00). The ACEC datalayer has been compiled by MCZM and DEM and includes both coastal and inland areas. EPA Designated Sole Source Aquifers Telephone: The Sole Source Aquifer datalayer was compiled by the Department of Environmental Protection (DEP) Division of Water Supply (DWS). Seven Sole Source Aquifers have been designated by the US Environmental Protection Agency (EPA) for Massachusetts. A Sole Source Aquifer (SSA) is an aquifer designated by US EPA as the sole or principal source of drinking water for a given aquifer service area; that is, an aquifer which is needed to supply 50% or more of the drinking water for that area and for which there are no reasonably available alternative sources should that aquifer become contaminated. The aquifers were defined by an EPA hydrogeologist. Aquifers Telephone: MassGIS produced an aquifer datalayer composed of 20 individual panels, generally based on the boundaries of the major drainage basins. Areas of high and medium yield were mapped. This datalayer includes polygon attribute coding to help in the identification of areas in which cleanup of hazardous waste sites must meet drinking water standards, as defined in the Massachusetts Contingency Plan (MCP) (310 CMR 40.00000). TC7268015.2s Page PSGR-2 PHYSICAL SETTING SOURCE RECORDS SEARCHED Non-Potential Drinking Water Source Areas Telephone: Non-Potential Drinking Water Source Areas (NPDWSA) are regulatory in nature representing one of many considerations used in determining the standards to which ground water must be cleaned in the event of a release of oil or hazardous material. NPDWSAs are not based on existing water quality and do not indicate poor ambient conditions. DEP Approved Zone IIs Telephone: The Department of Environmental Protection (DEP) approved Zone IIs datalayer was compiled by the DEP Division of Water Supply (DWS). The database contains 281 approved Zone IIs statewide. As stated in 310 CMR 22.02, a Zone II is ’that area of an aquifer which contributes water to a well under the most severe pumping and recharge conditions that can be realistically anticipated (180 days of pumping at safe yield, with no recharge from precipitation.) It is bounded by the groundwater divides which result from pumping the well and by the contact of the aquifer with less permeable materials such as till or bedrock. In some cases, streams or lakes may act as recharge boundaries. In all cases, Zone IIs shall extend up gradient to its point of intersection with prevailing hydrogeologic boundaries (a groundwater flow divide, a contact with till or bedrock, or a recharge boundary).’ These data are used in association with the Public Water Supplies datalayer. The following describes certain unique features of this association.\n - Any proposed new well which will pump at least 100,000 gallons per day must have a Zone II delineation completed and approved by DEP prior to the well coming on line. \n- Additionally, a new source may not be on-line yet, but other, older wells may fall within its Zone II boundary.\n - Further, existing wells must have a Zone II delineated as a condition of receiving a water withdrawal permit under the Water Management Act.

The brook bisects the former Pine Grove Golf Course, and eventually flows through Mass Audubon’s Arcadia Wildlife Sanctuary and into the Manhan River. The drainage area of Nashawannuck Brook is approximately 0.5 square miles at the point where the brook exits the City-owned parcel. The surrounding landscape was significantly altered by the development of the former golf course and associated support structures, leaving little of the natural landscape intact. The property is currently dominated by former upland fairways beginning to vegetate with more native plant species, some linear forest features, and assorted hard structures, including a non- jurisdictional dam forming an irrigation impoundment, the removal of which is the focus of this Sediment Management Plan (SMP). The dam is located on Nashawannuck Brook near the center of the Project area. The earthen dam is approximately 150 feet long and with a crest width of 10 feet with an approximately 0.5-acre impoundment. The dam is non-jurisdictional under the Massachusetts Dam Safety Regulations of 302 CMR 10.0000, and as such, is not recognized or evaluated by the Office of Dam Safety for condition or hazard class. Water flows out of the impoundment through an unmanaged water control structure that formerly housed boards for manipulating water level in the impoundment. The outlet of the dam is a deteriorated corrugated metal pipe that discharges to a constructed channel stretching several hundred yards downstream, beyond which the brook reverts back to a shallow stream bed with natural characteristics and morphology. Current access to the dam is from a pedestrian trail network on former golf cart paths, approximately 0.3 miles from the trailhead kiosk at Old Wilson Road. As part of the project decision making process, Tighe & Bond prepared a Sampling and Analysis Plan (SAP) in accordance with 314 CMR 9.00, (401 Water Quality Certification (WQC) program) requirements, to characterize the sediment within, and upstream and downstream of the impoundment. The plan was submitted to MassDEP on March 31, 2023 and approved by MassDEP on April 18, 2023. A copy of the SAP is included as Attachment A. Sediment sampling was performed by Tighe & Bond on April 27, 2023, with data presented in the Basis of Design report and herein. This SMP contains the information presented in the SAP, environmental due diligence review, and summarizes the results of our field data collection activities. The SMP addresses proposed sediment management alternatives to support dam removal activities and restoration of this stretch of the Nashawannuck Brook. Tighe&Bond Nashawannuck Brook - Sediment Management Plan 2-1 Section 2 Limited Due Diligence Review Tighe & Bond conducted a limited environmental due diligence review of publicly available records associated with the Project area and the general surrounding area. This review was performed to determine the potential for the sediment within the impoundment to have elevated concentrations of oil or hazardous materials (OHM), as defined in the Massachusetts Contingency Plan (MCP) 310 CMR 40.0000. A search of available Federal and State environmental records was obtained from Environmental Data Resources, Inc. (EDR®). A copy of the EDR report (the EDR Radius Map Report) is provided in Attachment A. The date of the most recent update by the regulatory agency maintaining each database is listed at the end of the EDR Radius Map Report. Those sites with adequate address information (geo-coded) are plotted on maps provided within the EDR Radius Map Report included in Attachment A. Sites with minimal address information (orphan sites) are listed separately in the report. The orphan sites were reviewed to determine whether they were potentially located in close proximity to the Project area. Tighe & Bond reviewed relevant files for select properties located within 1.0 mile of the Project area. Relevant files were reviewed on the Massachusetts Energy & Environmental Affairs (EEA) Data Portal search page for Waste Site & Reportable Releases. While it is not possible for Tighe & Bond to verify the accuracy and/or completeness of information contained in the EDR Radius Map report and the files reviewed, the use and reliance of this information is an accepted practice in the performance of environmental assessments and due diligence reviews. In addition to the EDR Radius Map Report, Tighe & Bond reviewed historical city directories, historical aerial photographs, and historical topographic maps obtained from EDR, a stormwater outfall map obtained from the City of Northampton’s website, and other reports provided by DER. Attachment A contains a summary of the relevant OHM use and reported releases, along with a completed copy of the EDR report reviewed as part of the 2023 Due Diligence Review. Tighe&Bond Nashawannuck Brook - Sediment Management Plan 3-1 Section 3 Soil and Sediment Volume Estimate 3.1 Total Sediment Volume Measurement As part of the sediment characterization effort, Tighe & Bond estimated the volume of soft sediment within the impoundment. Sediment thickness was measured at 20 locations distributed across the impoundment, using a graduated fiberglass probing rod. At each location, the probing rod was lowered over the side of a boat until resting on the top of sediment, and a depth to bottom measurement was recorded. The probing rod was then advanced through the soft sediment until refusal was encountered. The depth to refusal measurement was recorded, along with the type of refusal (i.e., soft or hard refusal), yielding a sediment thickness measurement. Attachment B is the survey base plan developed for the study area that includes 1-foot contours for the study area, and the elevation of “bottom of sediment” and depth of “soft sediment” at locations measured in the dam impoundment. The sediment probing performed as part of the survey found accumulated sediment above the Nashawannuck Dam impoundment’s hard bottom to be up to 2.6 feet thick, with a total estimated volume of soft sediment of approximately 550 cubic yards. 3.2 Volume Estimate Tighe & Bond estimated changes in sediment and soil volumes using Civil3D surface volume calculation tools. Surfaces were created for the dam removal preliminary design (included in the 2023 Basis of Design Report). The anticipated volume of sediment would be displaced by the channel laid out as part of the design (referred to as mobile sediment volume) is 200 cubic yards for the entire study area. However, instream processes resulting in downstream sediment transport could ultimately carry more sediment downstream than would be displaced by the brook shown on the drawings. For this reason, a mobile sediment management volume of 1.5 times the anticipated volume is recommended for permitting purposes, totaling approximately 300 cubic yards. This range would result in an anticipated mobilized fraction of sediment of between 36-percent and 54-percent when compared to the volume of sediment in impoundment. The computed volume includes non-mobile sediment that will need to be removed as part of the dam removal to allow for the construction of proposed improvements, which include abandoning the existing stream channel and relocating the channel to the southwest, slope stabilization and stream bank alterations to achieve desirable grades and compliment proposed walking paths and viewing areas. This sediment is assumed to migrate downstream prior to construction, but if not, some sediment (less than 100 CY) may need to be mechanically removed and reused onsite as fill at the former downstream channel. Tighe&Bond Nashawannuck Brook - Sediment Management Plan 4-1 Section 4 Sediment Sampling Plan and Results Pursuant to 314 CMR 9.07.2(b)(4), one sample for every 1,000 cubic yards of dredged sediment must be collected for projects proposing to manage less than 10,000 cubic yards, and a minimum of two samples per project are to be characterized. The sampling frequency for larger projects is established by a MassDEP-approved sediment sampling plan, although one sample per 1,000 cubic yards can be used as a guide. As part of the evaluation and design for dam removal activities and the restoration of Nashawannuck Brook, sediment sampling activities were performed throughout the project area. Sediment and soil sampling activities, and the subsequent laboratory analytical results, are described in the sections below. 4.1 Sediment Sampling 4.1.1 Sediment Sample Number and Location To establish an understanding of sediment quality throughout the project area, a total of four composite sediment samples were collected on April 27, 2023. The approximate location of each sediment sample is shown on Figure 1. Each composite sediment sample was prepared from three aliquots (grab samples). The sediment sample locations are described below: • Two composite samples were collected from the accumulated sediment profile within the Nashawannuck Dam impoundment. The locations were selected to provide an overview of sediment in the impoundment. • One composite sample was collected from upstream of the Nashawannuck Dam impoundment to evaluate background conditions and contributing sources of sediment. • One composite sample was collected from the depositional area at the downstream limits of the property to evaluate downstream sediment quality. Each aliquot was collected using hand tools and placed into a stainless-steel bowl for general characterization and sample preparation. Following collection and preparation, each composite sample was placed directly into laboratory-supplied containers. Samples submitted to the laboratory for volatile organic compound (VOC) analysis were collected from an individual aliquot, prior to preparation of the final composite sediment sample, and determined based on the highest total organic vapor (TOV) reading, using a photoionization detector (PID), however, no detectable TOVs were detected from the samples, so the VOC samples were collected from the “middle” aliquot of each composite sample. Four composite sediment samples were collected on April 27, 2023, identified as SED-101 through SED-104. The approximate location of each composite sediment sample is shown on Figure 1. Section 4 Pre-Characterization Tighe&Bond Nashawannuck Brook - Sediment Management Plan 4-2 4.1.2 Sediment Analytical Parameters Due diligence activities identified the need to supplement the required analytical parameters identified in 314 CMR 9.07(2)(b)(6) with pesticide and herbicide analyses, due to surrounding land use including agricultural land use and the former golf course. Each sample was submitted to a State-certified laboratory, with proper chain-of-custody protocols, and analyzed for the parameters consistent with the requirements of the 401 Water Quality Certification regulations: • Total Metals – Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, and Zinc; • EPHs with target PAHs; • Polychlorinated Biphenyls (PCBs) Congeners; • VOCs • Total Organic Carbon (TOC); • Percent water; • Grain Size Analyses; • Pesticides including DDT, DDE, DDD, Aldrin, Endrin, Dieldrin; • Herbicides; and, • Toxicity Characteristic Leaching Procedure (TCLP), as applicable. 4.1.3 Sediment Results The four sediment samples were analyzed by Phoenix Environmental Laboratories in Manchester, Connecticut. Laboratory analytical results from the sediment samples are presented in Table 4-1 in the MassDER sample results spreadsheet. A copy of the Phoenix Laboratories sediment analytical results is provided in Attachment D. Within Table 4-1, the sediment analytical results are compared to the following criteria: • Laboratory Reporting Limits (RLs) as specified within the 401 Water Quality Criteria regulations and listed in 314 CMR 9.07(2)(b)(6) • Stage 1 Freshwater Sediment Screening Criterion – Freshwater Sediment Screening Benchmarks as published in the US EPA Development and Evaluation of Consensus-Based Sediment Quality Guidelines for Freshwater Ecosystems (MacDonald, Ingersoll & Berger, 1999) • MassDEP Method 2 Direct Contact soil standards • MassDEP MCP Method 1 soil standards (S-1/GW-1) A comparison of the sediment analytical results to the criteria listed above, is provided below. 401 Water Quality Criteria RLs: • Laboratory Reporting Limits for all analyses met the required 401 Water Quality RLs. Stage 1 Freshwater Sediment Screening Criterion: Section 4 Pre-Characterization Tighe&Bond Nashawannuck Brook - Sediment Management Plan 4-3 • The laboratory reporting limit for non-detections exceeded the screening criterion in samples for the following compounds: acenaphthene, acenaphthylene, dibenz[a,h]anthracene, Gamma-BHC, Chlordane, Sum DDD, Sum DDE, Sum DDT, Dieldrin, Endrin, and Heptachlor Epoxide MassDEP MCP Method 1 S-1/GW-1 standards: • None of the detected concentrations exceeded the MCP Method 1 S-1/GW-1 standards Acenaphthylene was detected in samples SED-102 and SED-104 exceeding the Freshwater TEC ecological threshold. Additionally, dibenz[a,h]anthracene detected in sample SED-102 exceeded the freshwater TEC. Pesticides, herbicides, and VOCs were not detected in any of the samples above laboratory RLs. Concentrations of various metals and polycyclic aromatic hydrocarbons (PAHs) were detected in the sediment samples at concentrations exceeding the laboratory RL, which did not exceed any thresholds or standards. Positive detections in the sediment samples are summarized below: • SED-101 (Upstream): arsenic, cadmium, chromium, copper, lead, nickel, zinc, • SED-102 (Impoundment): arsenic, cadmium, chromium, copper, lead, mercury, nickel, zinc, acenaphthylene, benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[g,h,i]perylene, benzo[k]fluoranthene, chrysene, dibenz[a,h]anthracene, indeno[1,2,3-cd]pyrene, • SED-103 (Impoundment): arsenic, cadmium, chromium, copper, lead, mercury, nickel, zinc, benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, indeno[1,2,3-cd]pyrene, • SED-104 (Downstream): arsenic, cadmium, chromium, copper, lead, nickel, zinc, acenapthylene, benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[g,h,i]perylene, benzo[k]fluoranthene, chrysene, dibenz[a,h]anthracene, indeno[1,2,3-cd]pyrene The following physical properties of sediment samples were observed during sample collection and in laboratory analyses of total organic carbon and grain size distribution: • SED-101, the sample upgradient of the impoundment was observed to be comprised of tan fine to coarse sand and gravel. Total Organic Carbon (TOC) in this sample was 4,550 mg/kg. According to grain size analysis, the sample is comprised mainly of fine gravel and medium sand. • SED-102, collected within the impoundment was observed to be comprised of black mucky organics with some fine to medium sand. TOC in this sample was 38,300 mg/kg. According to the grain size analysis, the sample is comprised mainly of fine and medium sand, and fines. • SED-103, collected within the impoundment was observed to be comprised of black muck. TOC in this sample was 59,700 mg/kg. According to the grain size analysis, the sample is comprised mainly of fines. • SED-104, collected downstream of the impoundment was observed to be comprised of sandy and mucky material over tan silty clay. TOC in this sample was 7,970 mg/kg. According to the grain size analysis, the sample is comprised mainly of medium sand and fines. Section 4 Pre-Characterization Tighe&Bond Nashawannuck Brook - Sediment Management Plan 4-4 Corresponding with what was observed in the field during sample collected, samples collected within the impoundment had higher TOC values, and were comprised mainly of fines. Alternately, samples collected upstream and downstream of the impoundment had lower TOC values and were comprised of coarser materials. Tighe&Bond 5-1 Section 5 Sediment Management Recommendations The results of the sediment characterization sampling program were evaluated to identify appropriate sediment management options to support construction. Based on the characterization efforts described herein, potential materials management options are presented below. The City of Northampton is the property owner and considered the Generator of any materials that are to be managed off site. If it is determined that the excess materials will be managed off-site at an approved facility, they must be transported under a Material Shipping Record (MSR) signed by the Generator. As discussed in Section 4.1, contaminant concentrations detected in sediment samples collected from the brook and impoundment are indicative of good overall sediment quality. The few contaminants that were detected above laboratory reporting limits are generally present in similar concentrations upstream and downstream of the impoundment, with no significant difference variations in contaminant concentrations noted. As such, in Tighe & Bond’s opinion, there is flexibility in options for management of the sediment. The analytical results from the sediment sampling performed to date may be used to support on-site reuse and/or release of the sediment downstream. Sediment containing OHM concentrations below the applicable MCP RCS-1 criteria can be used as fill materials on-site and off-site (e.g., park, industrial, commercial, park, or residential locations). Based on the sediment characterization activities detailed within this report and the laboratory analytical results from the samples collected for analysis, the sediments from the project area are considered unregulated and are suitable for on-site reuse, including disposal/management in an upland environment, or managed off-site at a MassDEP- approved ACO facility. The sediments would also be suitable for passive instream management. The sediment can therefore be managed by natural (i.e., downstream migration) and mechanical (i.e., removing form site and either using for beneficial reuse or as fill at an ACO facility) methods. Instream management is anticipated during and following the dam removal wherein the Brook will reform within the former pond bottom within limits imposed by control points selected by the design team and approved by permitting agencies. During dam removal instream management is anticipated. For the purposes of the preliminary design approximately 200 to 300 cubic yards of sediment is assumed to transport downstream via natural release.

Azinheira, PE, CFM (Tighe & Bond); Daniel R. Buttrick, PE (Tighe & Bond) DATE: June 30, 2023 The purpose of this memorandum to document the hydrologic and hydraulic modeling performed as part of the Nashawannuck Brook Dam Removal project located at the former Pine Grove golf course in Northampton. Tighe & Bond updated HEC-RAS models developed by GZA GeoEnvironmental, Inc. (GZA) provided by the Massachusetts Division of Ecological Restoration (DER) as part of this study. In this memorandum Tighe & Bond notes changes made to the provided models and provides a brief summary of how the original models by GZA were developed. The project partners for this project include DER, the City of Northampton, and the Massachusetts Audubon Society (Mass Audubon). 1 Study Area Nashawannuck Brook is an intermittent stream that flows north to south through Northampton, draining into the Manhan River. The brook bisects the former Pine Grove golf course, and eventually flows through Mass Audubon’s Arcadia Wildlife Sanctuary and into the Manhan River. The drainage area of Nashawannuck Brook is approximately 0.5 square miles at the point where the Brook exits the City-owned parcel. The site was significantly altered by the development of the golf course and associated support structures, leaving little of the natural landscape intact. The site is currently dominated by rewilding upland fairways, some linear forest features, and assorted hard structures and a non-jurisdictional dam forming an irrigation impoundment. The City of Northampton purchased the former Pine Grove golf course and applied for and received a MA Municipal Vulnerability Preparedness Program Action Grant to complete a master plan for the site for this area. Nashawannuck Brook Dam is located on Nashawannuck Brook near the center of the project site. The earthen dam is approximately 150 feet long with a 10 foot wide crest and with an approximately 0.5-acre impoundment. The dam is non-jurisdictional under the Massachusetts Dam Safety Regulations of 302 CMR 10.00 and, as such, is not recognized or evaluated by the Office of Dam Safety for condition or hazard class. Typical jurisdictional dams in Massachusetts have storage volumes of, at minimum, 15 acre feet or structural heights of, at minimum, six feet. Water flows out of the impoundment through an unmanaged water control structure that formerly housed boards for manipulating the water level in the impoundment. The outlet of the dam is a deteriorated corrugated metal pipe. Current access to the dam is TECHNICAL MEMORANDUM Tighe&Bond -2- from a pedestrian trail network on former golf cart paths, approximately 0.3 miles from the trailhead kiosk at Old Wilson Road. The site is located within a Federal Emergency Management Agency (FEMA) approximate Zone A Special Flood Hazard Area (SFHA). FEMA does not compute base flood elevations within Zone A areas and FEMA does not have models available for this area. Figure 1 in Attachment A is a site location plan showing the location of the dam, and Figure 2 in Attachment A is an orthographic image of the site. 2 Modeling Methodology 2.1 Summary of Model Provided from GZA GeoEnvironmental, Inc. DER provided Tighe & Bond with the Nashawannuck Brook hydrologic and hydraulic model prepared by GZA, described in the Memorandum – Hydrologic and Hydraulic Models for Restoration Scenarios Nashawannuck Brook Restoration Project, Northampton, Massachusetts dated June 1, 2022. The model was prepared using the U.S. Army Corps of Engineers HEC-RAS modeling software, utilizing two-dimensional model components including direct rainfall and infiltration based on a Curve Number estimated by GZA. The model was developed using LiDAR data from GIS and a stream longitudinal profile by Field Geology Services, LLC. GZA performed an approximate calibration of the manning’s n values using peak flows from the USGS Streamstats program. GZA modeled direct precipitation into the study area using precipitation values from NOAA Atlas 14 and conservatively assuming a Soil Conservation Service (SCS) Type III rainfall distribution. 2.2 Model Verification Tighe & Bond verified that the hydrologic and hydraulic model provided produced the same results as previously published prior making updates to support the Nashawannuck Brook Dam Removal project. This check is required to verify the correct model runs are being used and to verify changes to results are due to changes Tighe & Bond is making and not some unknown variable (or error) caused by using a different version of the model or caused by data corruption. Table 2-1 shows a summary of the downstream flows published in the 2022 Memorandum with those computed by rerunning the existing GZA model (referred to as the “duplicate” model in this memorandum). Tighe & Bond produced identical results when rounding to the nearest cubic foot per second (cfs). Tighe & Bond also verified that the flood depths provided in the report were consistent with the model. Tighe & Bond concluded that the model was running correctly since the modeled downstream flows matched the 2022 Memorandum results and the flood depths were consistent.

Tighe & Bond evaluated three (3) alternatives as part of this study: 1. Existing Conditions 2. A “full” dam removal removing the entire dam embankment 3. A “partial” dam removal where some of the dam embankment remains in place (multiple “partial” dam removal alternatives were considered) Tighe & Bond made the following updates to the existing conditions model: 1. Incorporated topographic survey from 3D laser scanning using a Trimble X7, that included the dam embankment, three (3) control points, and approximately 200 feet upstream and downstream of dam. 2. Added detail to Nashawannuck Brook Dam geometry “storage area 2D connections” based on survey. These updates included reducing the size of the drop inlet weir from approximately 80 feet in the original model to approximately 14.5 feet to more closely match observed conditions. 3. Added the climate change scenario with rainfall input based on the Resilient MA Action Team (RMAT) tool available from the Massachusetts Office of Energy and Environmental Affairs (EEA). The climate change scenario is described in more detail in Section 4. Tighe & Bond made the following additional changes to create the “full” dam removal model scenario:  Deleted to the two “storage area 2D connections” originally used to represent the dam drop inlet structure and dam crest.  Added pond bathymetry based on field measurements collected by Tighe & Bond.  Modified the elevation terrain at the dam to match proposed dam removal AutoCAD drawings (more detail provided in Section 3). TECHNICAL MEMORANDUM Tighe&Bond -4-  Added a “proposed/anticipated” stream channel with geometry developed based on regression equations information from the USGS Streamstats (more detail provided in Section 3).  Modified the manning’s n so that the proposed stream had a manning’s n of 0.03 and the “former pond” areas outside the anticipated stream had a manning’s n of 0.1 assuming wetland vegetation develops. Tighe & Bond made the following additional changes to create the “partial” dam removal model scenario:  Added a “storage area 2D connection” to “block” a portion of the fully removed dam to create the partially removed scenario. Figure 2-1 shows the hydrology and hydraulics HEC-RAS 2D modeling extent over terrain.

The bankfull flow by definition causes stream levels to reach (but not exceed) the level of the channel banks. The channel width corresponding to bankfull flow is referred to as the bankfull width, with higher flow entering the floodplain where velocities tend to be lower. The existing channel at the site was constructed for the golf course so an accurate estimate of natural bankfull width was not possible using field indicators; therefore, Tighe & Bond estimated the bankfull width using regression estimates. Table 3-1 shows the bankfull width and depth estimates computed using regression equations available within the U.S. Geological Survey (USGS) Streamstats program, as well as the geometry used for modeling. Tighe & Bond estimated a low flow geometry using manning’s equation with a median flow of 0.34 cubic feet per second available from regression equations (Ries, K.G., III, 20001). Figure 3-1 shows the anticipated/approximate geometry used for modeling.

(http://pubs.usgs.gov/wri/wri004135) TECHNICAL MEMORANDUM Tighe&Bond -6- The path of the stream was estimated based on hard bottom topography in the pond, the preferred downstream channel location of the project partners, and topography downstream of the dam. As described in Section 2, Tighe & Bond evaluated two dam removal scenarios:  A “full” dam removal removing the entire dam embankment  A “partial” dam removal where some of the dam embankment remains in place For both proposed scenarios Tighe & Bond assumed the bankfull channel transitions into an inset floodplain “bench” on either side with varying width that transition into 4 horizontal units per one vertical unit (4H:1V) side slopes that extend to the existing grade at the dam abutments (for full removal) and embankment (for the partial removal). The “full” dam removal is anticipated to have a 75-foot wide inset floodplain (total width including bankfull channel of 85 feet) and the partial dam removal is proposed to have a 10-foot wide inset floodplain (total width including bankfull channel of 20 feet). Figure 3-2 shows a simplified section at the existing dam for existing conditions and both evaluated dam removal scenarios. Section 5.3 describes how the minimum partial dam removal scenario was developed. FIGURE 3-2 Simplified Section at Dam Embankment for Existing Conditions, Full Dam Removal, and Partial Dam Removal (looking downstream to upstream) 4 Climate Change Scenario Tighe & Bond evaluated a “climate change” rainfall event for each scenario using the methodology recommend by the Resilient MA Action Team (RMAT) Climate Resilience Design Standards Tool in accordance with the Massachusetts Environmental Policy Act (MEPA) Interim Protocol on Climate Change Adaptation and Resiliency. Attachment B is an evaluation of the site using the RMAT tool. Based on the RMAT tool output a “Tier 1” precipitation approach is required using 0.9 times the 90th percentile precipitation flow depth from NOAA Atlas 14 input directly into HEC-RAS. A SCS Type III rainfall distribution was used in HEC-RAS consistent with the existing model runs. Table 4-1 provides a summary of the 24-hour precipitation depths included for the model runs including the climate change scenario. Note that the 25-year frequency storm event in 2030 is anticipated to exceed the current NOAA Atlas 14 50-year frequency storm event.

Tighe & Bond evaluated the outflows and water surface elevations for the three evaluated scenarios. 5.1 Downstream Peak Flow Rate Table 5-1 shows the peak flows leaving the site for the evaluated storm events from the unmodified GZA model and the existing conditions incorporating survey data. The difference in peak flows between the two were either less than 1 cfs or less than 4 percent, and are considered reasonable given the updates described in Section 2.3.

The changes in peak flow rate before and after dam removal is an indicator as to whether a dam removal is expected to have downstream impacts. Table 5-2 shows results for peak flows at the downstream model extents for existing conditions, the full removal, and the partial removal. The peak outflow during the 100 year frequency storm event is anticipated to decrease following dam removal for both partial and full dam removal. The peak flows increase by less than 3 cfs and generally less than 3-percent for the dam removal scenarios compared to existing conditions for storm events less than the 100-year frequency storm TECHNICAL MEMORANDUM Tighe&Bond -8- event. Both dam removal alternatives produced similar peak flows at the downstream model extents. Attachment C shows outflow hydrographs for the evaluated scenarios at the downstream model extents (downstream end of property, peak flows provided in Table 5-2) and at the dam.

Both dam removal alternatives resulted in a slight reduction of 100-year frequency storm event peak flows decreased slightly, while less frequent events generally saw an increase in peak flow. Note modeling excluded rootwads and woody debris so additional reductions in flow may be anticipated. Other future anticipated stream restoration work (including constructing woody debris and adding sinuosity) are anticipated to reduce peak flows due to lengthening the stream channel and increasing roughness. 5.2 Water Surface Elevation and Depth One of the goals for dam removal projects is to lower upstream water levels; therefore, understanding the water surface elevation and how they change is critical for evaluated dam removals. Table 5-3, 5-4, and 5-5 show the water surface elevations, difference in water heights between existing conditions and both scenarios, and the modeled depth of water upstream of the downstream dam toe, respectively. Under existing conditions the dam is anticipated to pass the 10-year frequency storm event without overtopping but overtop during the 50-year storm event. Both removal scenarios result in water surface elevation reduction of at least eight (8) feet for the evaluated storm events compared to existing conditions, with a greater reduction anticipated if a full removal is performed.

Table 5- 6 shows the results for varying removal lengths during the 100-year storm event, notably the difference in 100-year storm event water levels upstream and downstream of the dam is 10 feet for existing conditions and 0.5 feet for a full removal. The difference in 100-year storm event water surface elevation upstream and downstream of the dam is an indicator of “how much impact” the remaining embankment is having on flow. The minimum 10-foot removal evaluated was found to result in an approximately two (2) foot drop in the 100-year water levels across the dam. This drop represents a minor amount of water impounded, but more significantly, the resulting drop will create an abnormally high velocity zone, jeopardizing stream stability, and was considered to still impound water. The partial dam removal geometry selected for this study was a 20-foot wide removal since it resulted in a drop of less than 1-foot during the 100-year storm event. Note that some drop in water levels is typically expected when moving from the upstream to the downstream direction.

Tighe & Bond understands that other “non-hydraulic” factors may impact the decisions of the project partners (e.g., cost). 5.5 Climate Change Implications Tighe & Bond evaluated the climate change scenario recommended from the RMAT tool of the 25-year frequency storm event in 2030, which is anticipated to be greater than the current NOAA Atlas 14 50-year frequency storm event. Both dam removal alternatives would result in water levels upstream of the dam decreasing by more than 9 feet compared to existing conditions. Both scenarios would result in increases in flow compared to existing conditions TECHNICAL MEMORANDUM Tighe&Bond -11- of less than 2% (and less than 1 cfs). It is Tighe & Bond’s opinion that this analysis will meet the requirements of MEPA. 6 Conclusion Tighe & Bond performed a hydrologic and hydraulic analysis for Nashawannuck Brook Dam to evaluate existing conditions and two dam removal alternatives. Tighe & Bond developed the model by updating an existing HEC-RAS model provided by DER. Conclusions from the analysis are:  A full removal or partial removal would significantly reduce water levels upstream of the dam while causing inconsequential changes to downstream flow. o Both scenarios would result in water surface elevation of at least eight (8) feet for the evaluated storm events, with a greater reduction anticipated if a full removal is performed. o The peak outflow during the 100-year frequency storm event is anticipated to decrease following dam removal for both partial and full dam removal. The peak flows increase by less than 3 cfs and generally less than 3-percent for the dam removal scenarios compared to existing conditions for storm events less than the 100-year frequency storm event.  The existing dam is anticipated to pass a 10-year storm event without overtopping but overtop during a 50-year storm event. o Water levels for both proposed removal alternatives would not reach the former embankment elevation during the 100-year storm event.  The evaluated full dam removal and partial dam removal are considered feasible hydraulically and are anticipated to provide ecological improvements. o The minimum recommended channel bottom removal width for a partial removal is 20 feet. o An approximately 10-foot wide bankfull channel is proposed with inset floodplains for both dam removal alternatives.  A climate change scenario was evaluated that will meet the requirements of MEPA.  The full removal provides a greater reduction in water levels versus a partial removal and therefore is considered the preferred hydraulic alterative. In Tighe & Bond’s opinion the updated modeling is appropriate to support the 40-percent design development. Tighe & Bond recommends the model be updated as part of subsequent design phases. The proposed 40-percent design will fall between the partial removal and full removal though closer to the full removal. \\tighebond.com\data\Data\Projects\M\M0944 Mass DFG\050 Nashawannuck Brook Dam Removal\Reports\Appendices\Appendix D Hydrologic and Hydraulic Evaluation\Nashawannuck Brook Dam Removal Hydrologic and Hydraulic Evaluation.docx Attachment A Full Size Figures BASIS OF DESIGN APPENDIX E Based on USGS Topographic Map forEasthampton, MA Revised 1979.Contour Interval Equals 10 feet.Circles indicate 500-foot and half-mile radii 0 1,000 2,000 Feet 1:24,000 V:\Projects\M\M0944\NashawannuckBrookRestoration\NashawannuckBrookRestoration_NorthamptonMA_Topo.mxd [Exported By: EMDrake, 3/6/2023, 6:42:37 PM] FIGURE 1SITE LOCATIONNashawannuck Brook Restoration ProjectNorthampton, Massachusetts March 2023 M-0944 ^_ ¹ÈSITE LOCATION Tighe&Bond OLDWILSONROADPINEGROVEDRIVE FIGURE 3ORTHOPHOTOGRAPH Nashawannuck Brook Restoration ProjectNorthampton, Massachusetts¹0 150 300 Feet 1:3,600 V:\Projects\M\M0944\NashawannuckBrookRestoration\NashawannuckBrookRestoration_NorthamptonMA_Ortho.mxd [Exported By: EMDrake, 3/6/2023, 6:42:54 PM] Based on MassGIS Color Orthophotography (2021) M0944 March 2023 ^_ Legend Parcel Boundary ÈSITE LOCATION Tighe&Bond Attachment B RMAT Tool Results BASIS OF DESIGN APPENDIX E Climate Resilience Design Standards Tool Project Report Nashawannuck Brook Restoration Project Date Created: 1/6/2023 3:05:08 PM Created By: aziter@tighebond.com Date Report Generated: 6/29/2023 4:24:42 PM Tool Version: Version 1.2 Project Contact Information: Sarah LaValley AICP (slavalley@northamptonma.gov) Project Summary Link to Project Estimated Capital Cost: $970000.00 End of Useful Life Year: 2026 Project within mapped Environmental Justice neighborhood: No Ecosystem Service Benefits Scores Project Score High Exposure Scores Sea Level Rise/Storm Surge Not Exposed Extreme Precipitation - Urban Flooding Moderate Exposure Extreme Precipitation - Riverine Flooding High Exposure Extreme Heat Moderate Exposure Asset Preliminary Climate Risk Rating Summary Number of Assets: 1 Asset Risk Sea Level Rise/Storm Surge Extreme Precipitation - Urban Flooding Extreme Precipitation - Riverine Flooding Extreme Heat Nashawannuck Brook ⎯⎯⎯ Natural Resource project assets do not receive a preliminary climate risk rating. ⎯⎯⎯ Climate Resilience Design Standards Summary Target Planning Horizon Intermediate Planning Horizon Percentile Return Period Tier Sea Level Rise/Storm Surge Nashawannuck Brook Extreme Precipitation Nashawannuck Brook 2030 Tier 1 Extreme Heat Nashawannuck Brook 2030 th Tier 1 Scoring Rationale - Project Exposure Score The purpose of the Exposure Score output is to provide a preliminary assessment of whether the overall project site and subsequent assets are exposed to impacts of natural hazard events and/or future impacts of climate change. For each climate parameter, the Tool will calculate one of the following exposure ratings: Not Exposed, Low Exposure, Moderate Exposure, or High Exposure. The rationale behind the exposure rating is provided below. ■  ■  ■  ■  ■  Page 1 of 6 Sea Level Rise/Storm Surge This project received a "Not Exposed" because of the following: Not located within the predicted mean high water shoreline by 2030 No historic coastal flooding at project site Not located within the Massachusetts Coast Flood Risk Model (MC-FRM) Extreme Precipitation - Urban Flooding This project received a "Moderate Exposure" because of the following: No historic flooding at project site No increase to impervious area Maximum annual daily rainfall is within 6 to 10 inches within the overall project's useful life Existing impervious area of the project site is less than 10% Extreme Precipitation - Riverine Flooding This project received a "High Exposure" because of the following: Part of the project is within a mapped FEMA floodplain, outside of the Massachusetts Coast Flood Risk Model (MC-FRM) Part of the project is within 100ft of a waterbody Project is potentially susceptible to riverine erosion No historic riverine flooding at project site Extreme Heat This project received a "Moderate Exposure" because of the following: Between 10% and 40% of the existing project site has canopy cover10 to 30 day increase in days over 90 deg.

Natural Resource assets do not receive a risk rating. The following factors are what influenced the risk ratings for each asset. Asset - Nashawannuck Brook Primary asset criticality factors influencing risk ratings for this asset: No score available Page 2 of 6 Project Climate Resilience Design Standards Output Climate Resilience Design Standards and Guidance are recommended for each asset and climate parameter. The Design Standards for each climate parameter include the following: recommended planning horizon (target and/or intermediate), recommended return period (Sea Level Rise/Storm Surge and Precipitation) or percentile (Heat), and a list of applicable design criteria that are likely to be affected by climate change. Some design criteria have numerical values associated with the recommended return period and planning horizon, while others have tiered methodologies with step-by-step instructions on how to estimate design values given the other recommended design standards.

Projected Duration of Flooding: NOT APPLICABLE Projected Design Flood Velocity: NOT APPLICABLE Projected Scour & Erosion: NOT APPLICABLE Extreme Precipitation Target Planning Horizon: 2030 LIMITATIONS: The recommended Standards for Total Precipitation Depth & Peak Intensity are determined by the user drawn polygon and relationships as defined in the Supporting Documents. The projected Total Precipitation Depth values provided through the Tool are based on the climate projections developed by Cornell University as part of EEA's Massachusetts Climate and Hydrologic Risk Project, GIS-based data as of 10/15/21. For additional information on the methodology of these precipitation outputs, seeSupporting Documents. While Total Precipitation Depth & Peak Intensity for 24-hour Design Storms are useful to inform planning and design, it is recommended to also consider additional longer- and shorter-duration precipitation events and intensities in accordance with best practices. Longer-duration, lower-intensity storms allow time for infiltration and reduce the load on infrastructure over the duration of the storm. Shorter-duration, higher-intensity storms often have higher runoff volumes because the water does not have enough time to infiltrate infrastructure systems (e.g., catch basins) and may overflow or back up during such storms, resulting in flooding. In the Northeast, short-duration high intensity rain events are becoming more frequent, and there is often little early warning for these events, making it difficult to plan operationally. While the Tool does not provide recommended design standards for these scenarios, users should still consider both short- and long-duration precipitation events and how they may impact the asset. The projected values, standards, and guidance provided within this Tool may be used to inform plans and designs, but they do not provide guarantees for future conditions or resilience. The projected values are not to be considered final or appropriate for construction documents without supporting engineering analyses.
