Willow Pond Look Park WSE Project No. 2100171 +A On behalf of the Look Park Board of Trustees, Weston Sampson Engineers, Inc. is hereby responding to comments provided by the Northampton Office of Planning Development, Massachusetts Department of Environmental Protection, and United States Army Corps of Engineers. Responses to each comment are provided below: Comment 1: The bank protection work will eventually need plans including cross sections. Response 1: Cross sections are provided on Plan D -1. Proposed grade will match existing grades with only surface armoring being replaced. C omment 2: The placing of the riprap gabions is considered discharge of fill material because it involves placing the rock below the ordinary high water of the pond (same as normal pool elevation). What part of the bank are you looking to stabilize- photos would be good here. Response 2: Bank area above and below the normal pool elevation will be stabilized with rip rap gabions along the western shore only. The calculated volume of 2,100 ft3 below normal pool elevation will be filled during bank stabilization. The bank stabilization will occur only on the western bank. Fill will be in areas that were previously excavated in order to receive the riprap and gabion wall. There will be a net fill of zero (0) cubic feet. C omment 3: The project as presently proposed does not appear to meet the General Performance Standards at 310 CMR 10.54(4)(a)4. and 5.; 310 CMR 10.56(4)(a)3. and 4., and potentially others. Use of riprap and gabion baskets in a setting described will have adverse affects on fisheries and wildlife habitat. Maintenance practices such as mowing to the edge of the Bank of Pond also has negative consequences to long -term stability. Therefore, the Department is advising that the project be redesigned to include maintenance best management practices; and that the plans be revised to comply with and be based upon the principles, methods, techniques, modeling, and requirements of the Natural Resources Conservation Service (NRCS) Stream Restoration Design Handbook, National Engineering Handbook Part 654 (Released September 20, 2007). Response 3: The bank where stabilization will occur is not considered a natural bank. Rather, the bank was originally designed as a recreational area and lined with rocks for stability (see photos, attached).

When it's essential...it's Weston&Sampso' Page 2 time, the rocks have been moved by visitors to the park, resulting in an unstabilized bank prone to erosion. In order to correct this problem the trustees are proposing to stabilize the bank with a combination of hard engineering solutions and plantings /bio stabilization. This combination will stabilize the bank, provide access for park visitors, and provide habitat for the local wildlife population. Please refer to the updated project description which explains the choice of a combination of riprap, gabion baskets and biostabilization as the preferred stabilization method for this project. Comment 4: Please provide an update as to the status of the USACOE Regional General Permit and MassDEP 401 Water Quality Certification. Have these been filed or issued? Response 4: A copy of the MassDEP 401 Water Quality Certification has been submitted in conjunction with this supplemental submittal. The USACOE Regional General Permit has been submitted and comments received from USACOE. Comment 5: Work for the culvert replacement will need plans Response 5: Culvert replacement will no longer be conducted as part of this project. The National Guard has determined that they cannot conduct the culvert replacement work for this project. Comment 6: All resource areas within the site must be shown on project plans. These include: bank, 100 foot and 200 foot riverfront area, vernal pool resource areas, intermittent streams, bordering land subject to flooding, all buffer zones under both the Wetlands Protection Act and Northampton Wetlands Ordinance, and the local `no- encroachment' zone. Any impacts to these areas that not quantified in the NOI must be identified, and detailed explanations of how the proposed work meets all applicable performance standards for these resource areas must be provided. Performance standards are not addressed in the existing materials. Response 6: Site plans have been modified to show resource areas and buffer zones. Additionally, Figure 4 is an Environmental Resource Map of the site. Applicable performance standards are addressed in the updated project description. Comment 7: Proof of mailing to NHE SP must be provided. The Conservation Commission will not be able to issue an Order of Conditions until an opinion from NHESP has been received, or 30 days from mailing has elapsed. Response 7: NHESP was provided a copy of the NOI at the same time as the NOI was sent to the Northampton Office of Planning Development. A response letter from NHESP has been provided with this updated submittal. The letter states that the proposed work will not be considered a "take" of any habitat. Comment 8: Please provide photographs of the pond and bank taken during growing season. Response 8: Photographs are provided as part of this updated submittal. Comment 9: Proof of notification of ACOE submittal to the Massachusetts Historical Commission, the Narraganset Tribe, the Wampanoag Tribe, the Stockbridge Munsee tribal community, and the Board of Underwater Archeological Resources. Response 9: Proof of notification to the above mentioned organizations are attached as part of this updated submittal. Comment 10: A permit may be required from the Northampton DPW under the Northampton Stormwater Ordinance. Weston &Sampson@, Response 10: A permit will be submitted per the Northampton Stormwater Ordinance. Comment 11: The application and narrative address only the impacts from the dredging project, but plan sheet C -4 includes the conversion of the eastern `recycle' area into a multi purpose playing field and parking lot. If this work is to be included in the current NOI, additional information about what is proposed, its impacts to resource areas, and detail sheets must be provided. Response 11: The parking lot is no longer part of the scope of work for this project. Sheet C -4 has been updated to address this change in project scope. The areas impacted have been calculated in the updated project description, however all of the work within both storage areas will be located only within buffer zones and no resource areas identified in 310 CMR 10.02(1)(a -f) will be altered. Comment 12: Since the pond will be completely drawn down, then the entirety of the Bank resource area will be impacted. Please update resource area impacts in the NOI. Response 12: Resource area impacts have been updated in the NOI to reflect the entirety of the bank being impacted due to drawdown. Comment 13: Is there an existing permit that allows the gate controlling the flow of water into the pond to be opened and closed? Response 13: There is no existing permit required to operate the gate valves. We hope that this letter and updated submittal material will fulfill all requirements and provide answers to the questions that have been put forth from the Northampton Office of Planning Development, Massachusetts Department of Environmental Protection, and United States Army Corps of Engineers.

Page 8 of 8 Project Description Background In 1928, one hundred and twenty -eight (128) acres of land were deeded to the City of Northampton by Mrs. Fanny Burr Look for the development of a memorial tribute to her late husband Frank Newhall Look. Current attendance at the Park is estimated to be half a million visitors annually. The Park is located at 300 North Main Street in Northampton, Massachusetts (Figure 1, Appendix B). One of the centerpieces of the park is Willow Pond, which has walking trails around its perimeter and allows for paddle boat recreation (Figure 2). Willow Pond, formerly known as Willow Lake, is a man- made dug pond, which covers approximately 2.5 acres of land and was created in the 1930's. Willow Pond was identified in the "Water Resources and Drainage Master Plan," completed by Baystate Environmental Consultants Baystate) in 2003, as one of the areas which will require continual maintenance in order to maintain its functionality within the park. The pond is fed by a man -made diversion of the Mill River, which is regulated by a gate valve located on the river's bank Baystate, 2003). Over time, sediment has accumulated at the bottom of the pond, making the pond shallower with each successive year. The sediment buildup has restricted access to paddle boats, which is the primary recreational purpose of the pond. To improve conditions in Willow Pond, maintenance dredging of the pond, while recycling the dredge materials to create multi purpose athletic fields, was proposed. The proposed project is similar in nature to work that was completed in 1984 by Baystate as an EPA Clean Lakes project. At that time, Baystate dredged approximately 7,000 c.y. of material (Willow Lake Restoration Construction Plans, Baystate 1984). All of the material was placed north of Willow Pond in an upland containment area. In addition to the dredging, several areas along the pond bank were armored using rip rap and stone pavers. Baystate conducted the necessary maintenance in 1984 in order to keep the pond operational for its current recreational use. In their 2003 Master Plan, Baystate identified these same issues, which were corrected in 1984, as areas to be addressed again in the near future. As stated above, since the last dredging was conducted in 1984, additional sediment has accumulated throughout the pond. In some areas less than two inches of water depth were observed in areas that historically had upwards of three feet of depth. In order to maintain the pond and keep it accessible for its recreational purpose, additional maintenance dredging must be completed. It is anticipated that as part of the maintenance of the pond, dredging will routinely be needed throughout its lifetime. Dredging was completed in 1984, is now proposed in 2011, and most likely will be required in another 20 -25 years. Bathymetry and Soft Sediment Survey On May 5, 2010, two Weston Sampson employees conducted a bathymetry and soft sediment survey at Willow Pond. Before entering the pond via boat, nine transects were created (Figure 3). Various points along these transects were measured for depth from the surface water to top of soft sediment and top of hard sediment. These measurements were taken using a marked probe rod. Each transect location was surveyed from shore by a third Weston Sampson employee. The reported depths of soft and hard sediment material were used to create bathymetric cross sections of the pond which are shown in Appendix C. Plan C -1 (Appendix D) shows the existing bathymetry of Willow Pond that was created using this data Using this information it was determined that approximately 7,500 cubic yards of material would need to be dredged in order to deepen the pond and maintain its current recreational use. This would result in the proposed bathymetry presented in Plan C -2. Proposed Work Dredging Willow Pond The proposed work is very similar in nature to previous work completed in Willow Pond in 1984. The initial phase of this dredging project was recently completed and included a wetland delineation of the area, a bathymetry survey of Willow Pond, and sediment sampling and analysis from Willow Pond. The results indicate that approximately 7,500 c.y. of material will be dredged as part of the project. To complete this work, approximately 2.5 acres of wetland (land under water), which constitutes the surface area of the pond, will be temporarily altered during the dredging operation. The pond is confined within steep banks and there is no associated bordering vegetated wetland (BVW) adjacent to the pond banks, which will be impacted. Minor bank repairs will be needed after dredging to restore the western bank, which has been damaged through vandalism. In addition to the in -pond impacts, the inlet and outlet streams will be temporarily dewatered, which could constitute a temporary impact of approximately 7,000 ft This area will be immediately restored once flow is returned to the streams after the dredging is completed. No additional impacts are anticipated. The areas of impact are provided in Table 1 for the entire project. In order to complete the dredging work, the gates that control the flow of water to Willow Pond will be closed and the water will be allowed to drain out of the pond. All remaining water will be pumped downstream. During drawdown, Park volunteers, under the supervision of both Park Officials and Conservation Agents, will collect all animal and fish species within the pond and transfer them downstream. The purpose of doing the work in the dry is to ensure that no impacts to environmental receptors outside of the pond are disturbed. By conducting the work in the dry, the possibility of downstream impacts caused by turbidity and associated sediment disturbance will be eliminated. Once the pond is drained, the material will be mechanically dredged from the pond using a back loader At this time it is anticipated that the National Guard will conduct this operation as part of their training operations. The material will be placed in a dump truck which will transport it within the park to the two proposed storage areas to dry. These areas are shown on Plan C -3 and C -4, with the proposed routes to access both sites. It is anticipated that the material will first go to the Recycling Area, which will be the Primary Sediment Storage Site, to dry. The site currently exists as a construction yard. Once the material is deposited in the storage areas, it will be given time to dry and then spread to form the base of the proposed athletic fields at the Recycling Area. The grading plan for this area is presented in Plan C -5 in Appendix D. The grading plan calls for the leveling and reseeding of the site. Any excess material will then be moved to the Secondary Sediment Storage Site, the Family Recreational Area. The grading plan for this area is presented in Plan C -6. Material will only be transported to this site once it has dried at the recycling area. Both areas are upland areas and the soils will pose no threat to any surrounding resource areas. Bank Stabilization After the dredging is complete, the west side of Willow Pond, which receives foot traffic from the park visitors, will be re- armored using a combination of a constructed gabion wall, riprap with stone screenings /tailings, and joint planting within the riprap. Currently, the slope exists as a previously altered earthen embankment armored with large diameter stones (12 -18" diameter). Over the last several years these stones have been removed and dislodged from the surface and thrown into the pond leaving unprotected earthen embankments, which have eroded in several areas (see Appendix K: Photos). While the pond is drained, the applicant wishes to stabilize the bank, prevent erosion, provide public access, provide habitat for local wildlife, and prevent bank vandalism. After exploring several different bank stabilization options, it was determined that a combination of Gabion wall, riprap, and joint planting in the riprap would best meet all of the above mentioned objectives of the bank stabilization project (see Alternatives Analysis, Appendix E). The plan protects the approximately 350' of the unprotected west bank. A 100 -foot Gabion wall will be placed in front of the band stand, at the center of the bank. This will enhance the visual aesthetics for visitors of the park. It will allow visitors direct access to the edge of the pond. The Gabion wall consists of one row of Gabion boxes, each requiring 3'x3'x3' boxes to be installed into the existing 2:1 slope. The wall will extend 1' below the high water line. A wood deck will be built on top of the wall, which will designed to match the grade at the top of slope Please see attached Construction Plans in Appendix D (Plan D -1 and D -2) and photos of the site in Appendix K, for more information. On both sides of the Gabion wall will be rip rap with joint plantings. The rip rap areas will replace the areas of the slope which currently contain pavers. These pavers have been dislodged and the bank underneath has been eroded. The purpose of the rip rap is to deter human activity along the bank and direct visitors to the Gabion wall area. The rip rap will also prevent erosion, while the joint planting will provide limited habitat and feeding areas for the local wildlife. To install the rip rap, the slope will be overcut and a layer of geotextile fabric and crushed stone will be placed on the slope to act as suitable bedding for a riprap protection layer. The slope will then be covered with a layer of 12 in. to 24 in. riprap chinked with smaller stones. The riprap layer will extend from several feet below the high water elevation to the crest of the bank. Please see the attached Construction Plans in Appendix D (Plan D -1 and D -2) for more information. The installation of the rip rap and gabion walls will result in approximately 2,100 ft (78 cy) of fill below the ordinary high water mark. This fill will be in areas that were previously excavated to handle the installation and therefore, will result in a net zero (0) fill for the stabilization portion of the project. Joint planting will be used in within the riprap to provide habitat, stabilization and visual appeal. This joint planting will disguise the riprap while plant roots help to stabilize soils. During installation of the rip rap, the cut ends of live stakes will be randomly placed into the soil behind the riprap through open spaces between the rocks, with the growing tips sticking out slightly above the rock. Please see the attached Construction Plans in Appendix D for more information. Meeting Applicable Performance Standards Massachusetts Wetlands Regulations 310 CMR 10.54 10.59 lists additional regulations for inland wetlands, including performance standards that must be met for work to be conducted in areas protected under the Wetlands Protection Act. Table 1, lists all of the impacted areas for the proposed project, including the dredging work, bank stabilization and alterations within both storage areas. A discussion of how the project meets the performance standards follows.

Area of Willow Pond impacted within BLSF Only 350 of this linear footage will be re- stabilized, the rest will only be temporarily impacts created during the dewatering of the pond. Bordering Vegetated Wetlands (BVW): Since there will be no work in the BVW, there will be no impact to BVW, thereby meeting all performance standards for BVW. 100 -Foot Wetlands Buffer Zone: The City of Northampton Wetlands Bylaw performance standards for work in the 100 -foot wetlands buffer zone include the following: The Commission may allow the alteration of up to 20% of the area within the fifty -foot to one hundred -foot buffer zone on a lot, or up to 2,000 square feet on a lot within a cluster subdivision. This is a total, cumulative allowance for all projects on a lot developed since the City first adopted a wetlands protection ordinance (August 17, 1989). The proposed work must have no significant adverse impact on the resource area, and the applicant must provide evidence deemed sufficient by the Commission that the area being disturbed will not harm the resource area values protected by the law. The City's general policy is no encroachment within 50 feet of wetlands. The Commission may allow work within the fifty -foot nonencroachment zone in response to a written request for a waiver, which shall include a written and plan view assessment as part of the application process as follows: (a) Projects in areas downgradient of wetlands and projects in areas already degraded by impervious surfaces from existing structures or pavement. (b) Projects in certain infill areas, in accordance with Table (1) in 337 -10, where development includes mitigation measures that will improve the existing condition of the wetlands or adjacent upland area and is otherwise permissible under the Massachusetts Wetlands Protection Act. (c) Limited development projects, as defined in the Massachusetts Wetlands Protection Act regulations. Discussion: The proposed project is not considered a development project, but rather a routine maintenance project. No negative impacts are expected to the resource area. Work in the 100 -foot wetlands buffer zone will occur on the western bank of Willow Pond (bank stabilization), at the recycling area, and at the family recreational area. The bank stabilization work on the western bank of Willow Pond will not adversely impact the buffer zone. The bank stabilization part of the project will actually increase bank stability by providing protection from erosion. The bank currently exists as a barren slope, spotted with stone pavers. By providing joint plantings throughout the rip rap area, the project is providing wildlife habitat and feeding areas that do not currently exist and add to the visual appeal of the bank. This added stability through rip rap, joint planting and Gabion wall will help in the protection of the wetland resource area (Willow Pond) by reducing stormwater runoff impacts. Total work area in the buffer zone for the bank stabilization part of this project is calculated to be approximately 3,500 ft Work in the recycling area will consist of disposal and spreading of sediment on -site, eventually transferring some of the dried sediment to the family recreation area. The recycling area is currently a clear -cut sand and gravel construction yard. Upon project completion, the recycling area will be an open, vegetated area with ball fields. It will be returned more to its natural setting than its current condition. The added vegetation will help to protect the wetland vegetation area to the east of the site by reducing stormwater runoff impacts. Total work area in the buffer zone for at the recycling area is calculated to be approximately 22,000 ft The family recreational area is currently an open field. Work in this area will consist of receiving and spreading dried sediment from the recycling area. The area will be re- vegetated and become an open field for recreational use. There will be no impacts to this area as it will be returned to its previous condition (open field) upon project completion. Total work area in the buffer zone for at the family recycling area is calculated to be approximately 68,000 ft All work within the buffer zones will enhance the ability of each site to protect the wetland resource area in which they buffer. During construction all resource areas will be protected with erosion control in order to eliminate the chance of erosion during the project. Land Under Water (LUW): The performance standards for any proposed work within Land Under Water Bodies and Waterways shall not impair the following: 1. The water carrying capacity within the defined channel, which is provided by said land in conjunction with the banks; 2. Ground and surface water quality; 3. The capacity of said land to provide breeding habitat, escape cover and food for fisheries; and 4. The capacity of said land to provide important wildlife habitat functions. A project or projects on a single lot, for which Notice(s) of intent is filed on or after November 1, 1987, that (cumulatively) alter(s) up to 10% or 5,000 square feet (whichever is less) of land in this resource area found to be significant to the protection of wildlife habitat, shall not be deemed to impair its capacity to provide important wildlife habitat functions. Additional alterations beyond the above threshold may be permitted if they will have no adverse effects on wildlife habitat, as determined by procedures established under 310 CMR 10.60. Discussion: There will be no change to water carrying capacity within a defined channel; no change in groundwater or surface water quality; no change in capacity of land in Willow Pond to provide breeding habitat, escape cover and food; no change in land under Willow Pond to provide important habitat functions. Although deepened, the pond will be restored to its original state All impacts will be temporary in nature and all flows and habitats will be restored post construction. Bordering Land Subject to Flooding (BLSF): The performance standards for any proposed work in BLSF include: 1. Compensatory storage shall be provided for all flood storage volume that will be lost as the result of a proposed project within Bordering Land Subject to Flooding 2. Work within Bordering Land Subject to Flooding, including that work required to provide the above specified compensatory storage, shall not restrict flows so as to cause an increase in flood stage or velocity. 3. Work in those portions of bordering land subject to flooding found to be significant to the protection of wildlife habitat shall not impair its capacity to provide important wildlife habitat functions. Discussion: There will be no net change in flood storage within the BLSF; no restriction of flow so as to cause an increase in flood stage or velocity; and will not impair BLSF land capacity to provide important wildlife habitat functions. The project will not alter or fill any areas within the floodplain. Bank: The performance standards for any proposed work on a Bank shall not impair the following: 1. the physical stability of the Bank; 2. the water carrying capacity of the existing channel within the Bank; 3. ground water and surface water quality; 4. the capacity of the Bank to provide breeding habitat, escape cover and food for fisheries; 5. the capacity of the Bank to provide important wildlife habitat functions. A project or projects on a single lot, for which Notice(s) of Intent is filed on or after November 1, 1987, that (cumulatively) alter(s) up to 10% or 50 feet (whichever is less) of the length of the bank found to be significant to the protection of wildlife habitat, shall not be deemed to impair its capacity to provide important wildlife habitat functions. Additional alterations beyond the above threshold may be permitted if they will have no adverse effects on wildlife habitat, as determined by procedures contained in 310 CMR 10.60. Discussion: The proposed project will actually improve the bank as far as Standards 1 -3 are concerned by providing protection from erosion, ensuring that the bank will continue to maintain its water carrying capacity, and improve surface water quality be removing sediment from stormwater flowing over the bank into Willow Pond. Although rip rap slopes and gabion walls hinder the banks ability to meet Standards 4 and 5, the bank currently exists as a barren slope, spotted with stone pavers. By providing joint plantings throughout the rip rap area, the project is providing wildlife habitat and feeding areas that do not currently exist. For a more thorough analysis of why the proposed techniques were selected in order to stabilize the bank, please see Appendix E, Alternative Analysis. Riverfront Protection Area (RPA): The performance standards for any proposed work in the RPA include: 1. Protection of Other Resource Areas. The work shall meet the performance standards for all other resource areas within the riverfront area, as identified in 310 CMR 10.30 (coastal bank), 10.32 (salt marsh), 10.55 (Bordering Vegetated Wetland), and 10.57 (Land Subject to Flooding). When work in the riverfront area is also within the buffer zone to another resource area, the performance standards for the riverfront area shall contribute to the protection of the interests of M.G.L. c. 131, 40 in lieu of any additional requirements that might otherwise be imposed on work in the buffer zone within the riverfront area. 2. Protection of Rare Species. No project may be permitted within the riverfront area which will have any adverse effect on specified habitat sites of rare wetland or upland, vertebrate or invertebrate species, as identified by the procedures established under 310 CMR 10.59 or 10.37, or which will have any adverse effect on vernal pool habitat certified prior to the filing of the Notice of Intent. 3. Practicable and Substantially Equivalent Economic Alternatives. There must be no practicable and substantially equivalent economic alternative to the proposed project with less adverse effects on the interests identified in M.G.L. c. 131 40. 4. No Significant Adverse Impact. The work, including proposed mitigation measures, must have no significant adverse impact on the riverfront area to protect the interests identified in M.G.L. c. 131, 40. Discussion: The work within the RPA meets all of the performance standards for all other resource areas within the riverfront area (Bank, BLSF, and LUW performance standard discussions, above). Natural Heritage and Endangered Species Program (NHESP) has noted that the project does not constitute a "take" of NHESP land (see attached NHESP letter in Appendix L). Since this project has been deemed maintenance work at the pond, there are no practicable and substantially equivalent economic alternatives to the proposed project with less adverse affects. Finally, the proposed work will have no significant impact on the riverfront area as the only work in this area will be bank stabilization along Willow Pond and dredging of Willow Pond. Sediment Sampling and Quality Results Sediment samples were taken at Willow Pond on May 5, 2010. A composite sediment sample (consisting of a mixture of three sediment samples in the same general area) was collected at three different locations. Results of the analysis showed that the sediment would be suitable for use in the athletic fields that are proposed. Results are discussed below and are attached in Appendix B. These samples were picked up on site the same day by a Con -Test Analytical Laboratory employee and taken to Con -Test for analysis. These three sediment samples, named SED1, through SED -3, were analyzed for VOCs, organic pesticides, SOCs, conventional chemistry parameters, EPH and metals. All VOCs, organic pesticides, SOCs and conventional chemistry parameter results were below detection limits. There were detections of a few EPH analytes as well as metals. Nickel was detected in SED -2 just below the Massachusetts Contingency Plan (MCP) state reporting limit of 20 mg/Kg. Because of this, it was decided that additional sediment samples would be taken at Willow Pond and analyzed for EPH and metals. On June 9, 2010, five (5) additional composite sediment samples were taken (SED -4 through SED -8) and sent to Con -Test Analytical Laboratory for analysis. Below is a table of analytes that were detected in the samples with an average value for the samples.

Sediment Quality Results Average values of the analytes were calculated to demonstrate that the composite sediment would be below any reporting limits once the material was dredged and mixed together. The average value of nickel is 13 mg /KG, which is well below the reporting limit of 20 mg /KG. Values from SED -4 were not considered in this averaging process because SED -4 was taken from the inlet stream, which feeds Willow Pond and will not be dredged as part of this project. Resource Area Protection During this project, silt socks will be installed on all traffic routes adjacent to any un- impacted wetlands (Appendix D). There are no storm drains within the park; therefore, no storm drain protection is necessary. At both the Family Recreational Area and the Recycle Area, a row of silt socks will be placed in locations shown on Plan C -4. This placement of erosion control is designed to protect un- impacted wetlands around the storage areas. In addition, a temporary 3 -foot high berm will be constructed on the down gradient side of the Recycle Area. Since the majority of the dewatering will occur in this storage area, the berm offers additional protection to the resource area down gradient. This berm will capture any water that flows overland prior to it reaching the wetland resource area. Please see the next section for a discussion of the Dredge Material Storage calculations, which utilize the 3 -foot high berm. The inlet and the outlet to the pond will remain dry during the project. These structures are man made and every effort will be used to ensure that any species using these channels are manually removed prior to the project. Once work is complete flow will be restored to these channels and to the pond itself. During the dewatering of Willow Pond, the majority of water will be allowed to drain from the pond by gravity. However, areas near the deepest parts of the pond may need to be pumped dry. A dewatering pump will be located at the staging area just southeast of the pond. Intake hoses will be run into the pond from that location. Outlet hoses will be run along the edge of the pond and outlet just downstream of the existing dam structure (see sheet C -4). Downstream of the outlet, a floating silt curtain will be installed. Please see Appendix G, Specification 02240 for a more detailed dewatering description. During dewatering, downstream monitoring of the stream channel will be required to assess potential impacts to the stream and the effectiveness of the environmental controls. The proposed monitoring plan will consist of the following activities: Resident engineer inspections on a regular basis directly downstream of the operations for the presence of suspended sediment, debris and/or sheen, and Turbidity monitoring using a turbidity meter to confirm that turbidity conditions meet permit requirements. Baseline monitoring upstream and downstream of the work will be performed prior to initiating work to determine baseline river turbidity levels. Corrective measures will be put implemented in the event that a sheen or unacceptable increase in turbidity is identified. These measures will include: Halting site operations to further evaluate the source of the observed conditions, Modifying the work to reduce the turbidity levels, and Improving and/or modifying the erosion controls. Dredge Material Storage Discussion and Calculation Approximately 7,500 cubic yards of dredged soil is proposed to be excavated from Willow Pond and then transported to a future ball field to the west of the pond. Material will be deposited on the west corner of the open field. This area is the furthest point from the wetlands and will receive the largest amount of fill material (approximately 4 feet). Dredged soil will be spread out in shallow lifts to encourage the soil to dry by evaporation or slowly draining out. Water draining out of the material will either leach into the ground beneath or sheet flow along the surface to one of two low areas of the recycling area. The two low areas will be contained by either a natural existing rise in topography (western edge along the access road) or a constructed berm (along the east perimeter). The two low laying areas exist in the western and eastern part of the field; see Sheet C -5 for existing contours. The amount of water which can drain out of a soil material is a function of the dredged soil characteristics. This can be measured by calculating the materials specific yield. Specific yield, also known as the drainable porosity, is a ratio, less than or equal to the effective porosity, indicating the volumetric fraction of the volume that a given material will yield when all the water is allowed to drain out of it under the forces of gravity: S r __V v VT Where: Vwd is the volume of water drained, and lTTi the total material volume Specific yield can be close to effective porosity, but there are several subtle things which make this value more complicated than it seems. Some water always remains in the formation, even after drainage; it clings to the grains of sand and clay in the formation. Also, the value of specific yield may not be fully realized for a very long time, due to complications caused by unsaturated flow. Below is a table illustrating differing specific yields for various soils types. Table 3: Specific Yields Values of specific yield, from Johnson (1967) Specific Yield Material min avg Max Unconsolidated deposits Clay 0 2 5 Sandy clay (mud) 3 7 12 Silt 3 18 19 Fine sand 10 21 28 Medium sand 15 26 32 Coarse sand 20 27 35 Gravelly sand 20 25 35 Fine gravel 21 25 35 Medium gravel 13 23 26 Coarse gravel 12 22 26 Consolidated deposits Fine grained sandstone 21 Medium grained sandstone 27 Limestone 14 Schist 26 Siltstone 12 Tuff 21 Other deposits Dune sand 38 Loess 18 Peat 44 Till, predominantly silt 6 Till, predominantly sand 16 Till, predominantly gravel 16 The material expected to be dredged from Willow Pond is a mixture of fine gravels and silty soils. Based on this expectation, the specific yield should range between 7 and 25 To be conservative we have assumed a specific yield of 25 Thus, approximately 1,900 cubic yards (c.y.) of water could potentially runout from the deposited material. This also assumes no water loss for infiltration or evaporation. The majority of the water can drain to the western side of the site, which can allow water to be stored over 4 feet deep with a capacity over 1,600 c.y. The second location to the eastern side will have a 3 -foot high constructed berm with a capacity of at least 1,300 c.y. Thus, between the two locations there is ample storage for water from the dredged soil.

LOOSE COMPOST LAYER 0: \Northampton MA \Look Park Willow Lake \Look Pork—Permitting \CADD \DETAILS.dwg Alternatives for Addressing Willow Pond Dredging Alternative 1 No Action Over the last several years, sediment has accumulated at the bottom of the Willow pond, making the pond shallower with each successive year. The sediment buildup has restricted access to paddle boats, which is the primary recreational purpose of the pond. In some areas less than two inches of water depth were observed in areas that historically had upwards of three feet of depth. In order to maintain the pond and keep it accessible for its recreational purpose, additional maintenance dredging must be completed. If no action is completed the pond will continue to get shallower and all access will be restricted. The pond is a centerpiece to Look Park and without it a number of recreational activities would be eliminated. Alternative 2 Hydraulic Dredging Hydraulic Dredging can be completed while the pond remains in its current state. This dredging technique requires a boat, which floats on the water and excavates the sediment using pumps. The pump essentially vacuums the material from the bottom of the pond and pumps it through a temporary pipeline to an offsite location. With a hydraulic dredge, the dredge discharge line and return line are the only obstructions in the environment. The lines are usually laid on the ground surface. Advantages: The advantages to the Hydraulic dredge alternative include: The pond, inlet and outlet do not need to be drained. The actual dredging requires almost no heavy machinery Disadvantages: The disadvantages to the Hydraulic dredge alternative include: Once removed the sediment will need to be dewatered or pressed. This process can be messy and result in a lot of excess water, which can flow into un- impacted resource areas. Requires a large cleared area near the pond to conduct the drying or pressing. This area would need to be in close proximity to the pond so the sediment can be dried prior to transport to the two sediment storage areas. This would require further alteration of the park and it's grounds. Because the pond is never drained there is no opportunity to protect aquatic and benthic species that will be impacted by the vacuum. The primary contractor for the work is the National Guard. They will be conducting the work as part of their training operations. The Guard does not conduct Hydraulic dredging. Hydraulic dredgers can be costly when comparing them to the National Guard, who is planning on doing the work for free as part of their training operations. Alternative 3 Mechanical Dredging in the Dry Preferred alternative Mechanical Dredging in the dry requires the pond to be drained and the sediment allowed to dry. Once dry the sediment is mechanically moved with backhoes and heavy equipment to a storage site where the sediment will continue to dry until it can later be re -used. Advantages: The advantages to the Mechanical dredge alternative include: More care can be taken to remove all aquatic and benthic species from the pond prior to dredging By drying the sediment it reduces the risk of material being transferred to un- impacted sites through the dewatering process. Most impacts are temporary in nature and are a result of the dewatering. A dewatering/pressing area adjacent to the pond will not be necessary, as the soils will be drained within the pond limits. It is the selected form of dredging of the National Guard Disadvantages: The disadvantages to the Mechanical dredge alternative include: It requires the use of heavy machinery in wetland resource areas Requires drying of the entire site Alternatives for Addressing Bank Stabilization in Willow Pond Alternative 1 No Action: The west side of Willow Pond, which receives foot traffic from the park visitors, has been vandalized over the last several years. Currently, the slope exists as an earthen embankment armored with large diameter stones (12 -18" diameter). These stones have been dislodged from the surface and thrown into the pond leaving unprotected earthen embankments. These embankments have eroded in several areas and are currently contributing to the sediment buildup in Willow Pond. If No action is conducted the stones will continue to be dislodged and more areas will be susceptible to erosion. Alternative 2 Bio- Stabilization (Brush Layering) to Protect the Slope In order to protect the bank, a bio- stabilization technique could be used to help prevent access and vandalism on the bank. One possible method would be the "brush layering" method. This method includes the layering of cuttings on horizontal benches that follow the contour of the bank. This will provide shallow stability to the bank, reduce soil erosion, and provide habitat for breeding and feeding for the local wildlife. However, this vegetative cover would also defeat the recreational purposes of the pond, as access to the pond for fishing, boating, etc. is a big part of the ponds recreational uses. The brush layering will act as a buffer for visitors of the park. Any vegetation on the bank which hinders the visitor's ability to access the pond would not suit the purpose of the pond as a recreational area. Furthermore, 3 of the bank around the pond is inaccessible due to vegetation and topography. This small portion of the bank is the only area that maintains access for park visitors. There is also a bird sanctuary island which provides habitat and is restricted from park visitors. Alternative 3 Re- armoring of the Slope Rip Rap and Gabion Wall A 100 -foot Gabion wall will be placed in front of the band stand, at the center of the bank. This will enhance the visual aesthetics for visitors of the park. It will allow visitors direct access to the edge of the pond. The Gabion wall consists of one row of Gabion boxes, each requiring 3'x3'x3' boxes to be installed into the 2:1 slope. The wall will extend 1' above the high water line. A wood deck will be built on top of the wall. Please see attached Construction Plans in Appendix D (Plan D -1 and D -2) for more information. On both sides of the Gabion wall will be a rip rap slope. The rip rap areas will replace the areas of the slope which currently contain pavers. These pavers have been dislodged and the bank underneath has been eroded. The purpose of the rip rap is to deter human activity along the bank and direct visitors to the Gabion wall area. The rip rap will also prevent erosion. To install the rip rap, the bank will be overcut and a layer of geotextile fabric and crushed stone will be placed on the slope to act as suitable bedding for a riprap protection layer. The slope will then be covered with a layer of 12 in. to 24 in. riprap chinked with smaller stones. The riprap layer will extend from several feet below the high water elevation to the crest of the bank. While this alternative would provide slope stability, access to the pond by visitors, and reduce vandalism by way of larger, heavier rocks that cannot be easily moved, it would not provide habitat or feeding areas for wildlife along this bank. Alternative 4 Combination of Bio- Stabilization, Rip Rap and Gabion Wall (Preferred Alternative) This alternative would be similar to Alternative 3, above, but would include bio- stabilization by way of joint planting. Joint planting will be used within the riprap to provide habitat, stabilization and add visual appeal. This joint planting will disguise the riprap while plant roots help to stabilize soils. The cut ends of live stakes will be randomly placed into the soil behind the riprap through open spaces between the rocks, with the growing tips sticking out slightly above the rock. Through the combination of bio- stabilization, rip rap and gabion wall, all of the objective will be met, including bank stabilization, visually pleasing aesthetics, erosion prevention, public access, habitat for wildlife, and bank vandalism prevention. As such, this is considered the preferred alternative. Important: When filling out forms on the computer, use only the tab key to move your cursor do not use the return key.

Adams, P.E. concerning Standards 1 -10 as they apply to the Look Park General: Willow Pond was identified in the "Water Resources and Drainage Master Plan," completed by Baystate Environmental Consultants (Baystate) in 2003, as one of the areas which will require continual maintenance in order to maintain its functionality within the park. The pond is fed by a man -made diversion of the Mill River, which is regulated by a gate valve located on the river's bank (Baystate, 2003). Over time, sediment has accumulated at the bottom of the pond, making the pond shallower with each successive year. The sediment buildup has restricted access to paddle boats, which is the primary recreational purpose of the pond. To improve conditions in Willow Pond, maintenance dredging of the pond, while recycling the dredge materials to create multi purpose athletic fields, was proposed. Dredged material will be removed and placed at the Recycle Area to dewater. After being dewatered, the site will be leveled, with extra material being removed and placed on the Family Recreational Area where it will be leveled. Both sites will eventually be turned into ballfields. Bank stabilization, including rip -rap and gabion walls, will occur on the western bank of Willow Pond. The proposed project is similar in nature to work that was completed in 1984 by Baystate as an EPA Clean Lakes project. At that time, Baystate dredged approximately 7,000 c.y. of material (Willow Lake Restoration Construction Plans, Baystate 1984). All of the material was placed north of Willow Pond in an upland containment area. In addition to the dredging, several areas along the pond bank were armored using rip rap and stone pavers. Baystate conducted the necessary maintenance in 1984 in order to keep the pond operational for its current recreational use. In their 2003 Master Plan, Baystate identified these same issues, which were corrected in 1984, as areas to be addressed again in the near future. As stated above, since the last dredging was conducted in 1984, additional sediment has accumulated throughout the pond. In some areas less than two inches of water depth were observed in areas that historically had upwards of three feet of depth. In order to maintain the pond and keep it accessible for its recreational purpose, additional maintenance dredging must be completed. It is anticipated that as part of the maintenance of the pond, dredging will routinely be needed throughout its lifetime. Standard 1: No New Untreated Discharges The proposed project will create no new untreated discharges. No new impervious area will be created during this project. The armoring being added to the west bank will be impervious in nature. Standard 2: Peak Rate Attenuation Since there will be no increase in impervious area, post development (post- improvement) peak discharge rates will not exceed pre development (pre- improvement) peak discharge rates. To ensure that the work incorporates the performance standards recommended in the DEP 's Stormwater Management Policy, necessary erosion and sedimentation control measures will be utilized during construction. These measures will include silt socks around Willow Pond, The Family Recreational area and the Recycle area as depicted on the site plans. Standard 3: Recharge As noted in the Standard 2 explanation, the impervious area in the work area will not be increased at the completion of the project. Therefore, recharge rates will not change in the work area at the end of the project. Standard 4: Water Quality The proposed work will not change water quality at the site. There will be no increase in stormwater flow, and the design for dam improvements will not increase soil erosion. During the project, appropriate BMPs will be used to minimize sedimentation and soil erosion. Standard 5: Land Uses with Higher Potential Pollutant Loads LUHPPLs) Not Applicable. There are no LUHPPLs in the work area. Standard 6: Critical Areas There will be no new discharge to critical areas. Standard 7: Redevelopments and Other Projects Subject to the Standards Only to the Maximum Extent Practicable This is a re- development and limited project which will minimize disturbance to existing trees and shrubs. Standard 8: Construction Period Pollution Prevention and Erosion and Sediment Control A detailed Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan is included. To ensure that the work incorporates the performance standards recommended in the DEP's Stormwater Management Policy, necessary erosion and sedimentation control measures will be utilized during construction. These measures will include silt socks around Willow Pond, the Family Recreational area and the Recycle area as depicted on the site plans. Standard 9: Operation and Maintenance Plan An operations and maintenance plan is not needed since there will not be any new stormwater management systems put in place in the project work area. Standard 10: Prohibition of Illicit Discharges By the nature of the proposed work, there will be no illicit discharges. There will be no opportunity for illicit discharges into the system. Registered Professional Engineer's Certification I have reviewed the Stormwater Report, including the soil evaluation, computations, Long -term Pollution Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long -term Post Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement (if included) and the plans showing the stormwater management system, and have determined that they have been prepared in accordance with the requirements of the Stormwater Management Standards as further elaborated by the Massachusetts Stormwater Handbook. I have also determined that the information presented in the Stormwater Checklist is accurate and that the information presented in the Stormwater Report accurately reflects conditions at the site as of the date of this permit application. Registered Professional Engineer Block and Signature Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan SECTION 1: Introduction Willow Pond was identified in the "Water Resources and Drainage Master Plan," completed by Baystate Environmental Consultants (Baystate) in 2003, as one of the areas which will require continual maintenance in order to maintain its functionality within the park.

In order to maintain the pond and keep it accessible for its recreational purpose, additional maintenance dredging must be completed. It is anticipated that as part of the maintenance of the pond, dredging will routinely be needed throughout its lifetime. As part of this project, this "Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan" has been created to insure that no further disturbance to the wetland resource is created during the construction of these repairs. SECTION 2: Construction Period Pollution Prevention Measures Best Management Practices (BMPs) will be utilized as Construction Period Pollution Prevention Measures to reduce potential pollutants and prevent any off -site discharge. The objectives of the BMPs for construction activity are to minimize the disturbed areas, stabilize any disturbed areas, control the site perimeter and retain sediment. Both erosion and sedimentation controls and non stormwater best management measures will be used to minimize site disturbance and ensure compliance with the performance standards of the WPA and Stormwater Standards. Measures will be taken to minimize the area disturbed by construction activities to reduce the potential for soil erosion and stormwater pollution problems. In addition, good housekeeping measures will be followed for the day -to -day operation of the construction site under the control of the contractor to minimize the impact of construction. This section describes the control practices that will be in place during construction activities. All recommended control practices will comply with the standards set in the MA DEP Stormwater Policy Handbook. 2.1 Minimize Disturbed Area and Protect Natural Features and Soil In order to minimize disturbed areas all work will be completed within well- defined work limits. These work limits are shown on the construction plans (Appendix D). The Contractor shall not disturb native vegetation in the undisturbed wetland area without prior approval from the Engineer. The Contractor will be responsible to make sure that all workers know the proper work limits and do not extend their work into the undisturbed areas. The protective measures are described in more detail in the following sections. 2.2 Control Stormwater Flowing onto and through the project All construction areas adjacent to wetlands will be lined with silt socks. The silt socks will be inspected daily and accumulated silt will be removed as appropriate. A stabilized truck entrance /exit, located at the south of Willow Pond, is proposed so that equipment visiting the site can remove any accumulated dirt and mud from vehicles to prevent tracking the mud onto public roads. 2.3 Stabilize Soils The Contractor shall take account of the conditions of the soil where erosion control seeding will take place to insure that materials used for re- vegetation are adaptive to the sediment control. The western wall of the Pond will be armored with alternating rip -rap and gabion walls to reduce the likelihood of erosion. 2.4 Proper storage and cover of any stockpiles The location of the Contractor's storage areas for equipment and/or materials shall be upon cleared portions of the job site or areas to be cleared as a part of this project, and shall require written approval of the Engineer. No excavated materials or materials used in backfill operations shall be stored within a minimum distance of fifty (50) feet of any watercourse. Adequate measures for erosion and sediment control such as the placement of silt socks around the downstream perimeter of stockpiles shall be employed to protect any downstream areas from siltation. There shall be no storage of equipment or materials in areas designated as wetlands. The Engineer may designate a particular area or areas where the Contractor may store materials used in his operations. 2.5 Perimeter Controls and Sediment Barriers Erosion control lines as described in Section 5 will be utilized to ensure that no sedimentation occurs outside the perimeter of the work area. 2.6 Storm Drain Inlet Protection There are no storm drains in the work area. 2.7 Retain Sediment On Site The Contractor will be responsible to monitor all erosion control measures. Whenever necessary the Contractor will clear all sediment from the silt socks that have been silted up during construction. Daily monitoring should be conducted using the attached Monitoring Form. The following good housekeeping practices will be followed on -site during the construction project: 2.8 Material Handling and Waste Management All materials stored on -site will be stored in a neat, orderly manner in appropriate containers. All materials will be kept in their original containers with the original manufacturer's label. Substances will not be mixed with one another unless recommended by the manufacturer. All waste materials will be collected and stored in a securely lidded metal container from a licensed management company. The waste and any construction debris from the site will be hauled off -site daily and disposed of properly. The contractor will be responsible for all waste removal. Manufacturer's recommendations for proper use and disposal will be followed for all materials. Sanitary waste will be collected from the portable units a minimum of once a week, by a licensed sanitary waste management contractor. 2.9 Designated Washout Areas The Contractor shall use washout facilities at the staging area/truck wash area, located to the south of Willow Pond. 2.10 Proper Equipment/Vehicle Fueling and Maintenance Practices On -site vehicles will be monitored for leaks and receive regular preventative maintenance to reduce the risk of leakage. To ensure that leaks on stored equipment do not contaminate the site, oil- absorbing mats will be placed under all equipment during storage. Regular fueling and service of the equipment may be performed using approved methods and with care taken to minimize chance of spills. Repair of equipment or machinery within the 100' water resources area shall not be allowed without the prior approval of the Engineer. Any petroleum products will be stored in tightly sealed containers that are clearly labeled. 2.11 Equipment/Vehicle Washing The Contractor will be responsible to ensure that no equipment is washed on -site unless at the staging area/truck wash area. SECTION 3: Spill Prevention and Control Plan The Contractor will be responsible for preventing spills in accordance with the project specifications and applicable federal, state and local regulations. The Contractor will identify a properly trained site employee, involved with the day -to -day site operations to be the spill prevention and cleanup coordinator. The name(s) of the responsible spill personnel will be posted on -site. Each employee will be instructed that all spills are to be reported to the spill prevention and cleanup coordinator. 3.1 Spill Control Equipment Spill control/containment equipment will be kept in the Work Area. Materials and equipment necessary for spill cleanup will be kept either in the Work Area or in an otherwise accessible on -site location. Equipment and materials will include, but not be limited to, absorbent booms /mats, brooms, dust pans, mops, rags, gloves, goggles, sand, plastic and metal containers specifically for this purpose. It is the responsibility of the Contractor to ensure the inventory will be readily accessible and maintained. 3.2 Notification All workers will be directed to inform the on -site supervisor of a spill event. The supervisor will assess the incident and initiate proper containment and response procedures immediately upon notification.

Loam shall be at least 6 inches compacted thickness. B. Lime shall be applied to bring the pH to 6.5 or, without a soil test, at the rate of 2 -3 tons of lime per acre. C. Fertilizer shall be applied according to the soil test, or without a soil test, at the rate of 1000 pounds per acre. D. Loam shall be worked a minimum of 3 inches deep, thoroughly incorporating the lime and fertilizer into the soil. The loam shall then be raked until the surface is finely pulverized and smooth and compacted with rollers, weighing not over 100 pounds per linear foot of tread, to an even surface conforming to the prescribed lines and grades. Minimum depth shall be 6- inches after completion. 3.02 SEEDING: A. Seeding shall be done when weather conditions are approved as suitable, in the periods between April 1 and May 30 or August 15 to October 1, unless otherwise approved. B. If there is a delay in seeding, during which weeds grow or soil is washed out, the Contractor shall remove the weeds or replace the soil before sowing the seed, without additional compensation. Immediately before seeding is begun, the soil shall be lightly raked. C. Seed shall be sown at the approved rate, on a calm day by machine. D. One half the seed shall be sown in one direction and the other half at right angles. Seed shall be raked lightly into the soil to a depth of 1/4 inch and rolled with a roller weighing not more than 100 pounds per linear foot of tread. E. The surface shall be kept moist by a fine spray until the grass shows uniform germination over the entire area. Wherever poor germination occurs in areas larger than 3 sq. ft., the Contractor shall reseed, roll, and water as necessary to obtain proper germination. F. The Contractor shall water, weed, cut and otherwise maintain and protect seeded areas as necessary to produce a dense, healthy growth of perennial lawn grass. 02/21/2006 02920 -4 G. If there is insufficient time in the planting season to complete the fertilizing and seeding, permanent seeding may be left until the following planting season, at the option of the Contractor or on order of the Engineer. In that event, a temporary cover crop shall be sown. This cover crop shall be cut and watered as necessary until the beginning of the following planting season, at which time it shall be plowed or harrowed into the soil, the area shall be fertilized and the permanent seed crop shall be sown as specified. 3.03 PLACING MULCH: A. Hay or Straw Mulch shall be loosely spread to a uniform depth over all areas designated on the plans, at the rate of 4 -1/2 tons per acre, or as otherwise directed. B. Hay or Straw Mulch may be applied by mechanical apparatus, if in the judgment of the Engineer the apparatus spreads the mulch uniformly and forms a suitable mat to control slope erosion. The apparatus shall be capable of spreading at least 80 percent of the hay or straw in lengths of 6- inches or more, otherwise it shall be spread by hand without additional compensation. C. Wood Fibre Mulch shall be uniformly spread over certain selected seeded areas at the minimum rate of 1,400 pounds per acre unless otherwise directed. It shall be placed by spraying from an approved spraying machine having pressure sufficient to cover the entire area in one operation. 3.04 SEEDING AND MULCHING BY SPRAY MACHINE: A. The application of lime, fertilizer, grass seed and mulch may be accomplished in one operation by the use of an approved spraying machine. The materials shall be mixed with water in the machine and kept in an agitated state in order that the materials may be uniformly suspended in the water. The spraying equipment shall be so designed that when the solution is sprayed over an area, the resulting deposits of lime, fertilizer, grass seed and mulch shall be equal to the specified quantities. B. A certified statement shall be furnished, prior to start of work, to the Engineer by the Contractor as to the number of pounds of limestone, fertilizer, grass seed and mulch per 100 gallons of water. C. This statement should also specify the number of square yards of seeding that can be covered with the solution specified above. If the results of the spray operation are unsatisfactory, the Contractor will be required to abandon this method and to apply the lime, fertilizer, grass seed and mulch by other methods. 3.05 INSPECTION AND ACCEPTANCE: At the beginning of the planting season following that in which the permanent grass crop is sown, the seeded areas will be inspected. Any section not showing dense, vigorous growth 02/21/2006 02920 -5 Document 1 at that time shall be promptly reseeded by the Contractor at his own expense. The seeded areas shall be watered, weeded, cut and otherwise maintained by the Contractor until the end of that planting season, when they will be accepted if the sections show dense, vigorous growth.

Applica i ignatu //.291D Dat CC: INTEROFFICE MEMORANDUM TO: FILE FROM: MEL HIGGINS (WESTON SAMPSON, INC.) SUBJECT: LOOK PARK WETLANDS DELINEATION DATE: MAY 6, 2010 On May 4, 2010, two Weston Sampson, Inc. personnel, trained in the U.S. Army Corps of Engineers Wetland Delineation Manual, located wetlands at the Frank Newhall Look. Memorial Park. Look Park is located at the intersection of Bridge Road and North Main Street (Route 9) in Northampton Massachusetts. The wetlands are associated with Willow Lake, perennial stream and intermittent stream, all located within the park. The wetland boundaries were marked using pink flagging. The wetland resource area associated with Willow Lake was delineated using the edge of water as the area surrounding the lake either had a steep bank from the waters edge, was maintained (cut grass) or was a concrete wall associated with a boat launch or dam. Wetland flags were only hung at the eastern portion of the lake as this was the only area with vegetation from which to hang flags. The edge of water /top of bank and wetlands flags were surveyed the following day by Weston Sampson, Inc. personnel on May 5, 2010. Wetland flags associated with the unnamed perennial stream flowing into Willow Lake were numbered WF -1C WF -30C. Wetland flags associated with the open field that is proposed to receive dredged material from Willow Lake were numbered WF -1D —WF-42D. Two 10 x 10 foot wetland plots were investigated at the site.

Wetlands File Ne:' ACoE Application N2: Dear Mr. Ellerbrook: The Department has reviewed your application for the referenced Water Quality-Certification (WQC). In accordance with the provisions of Section 401 of the Federal Clean Water Act as amended (33 U.S.C. §1251 et sec.), MGL c.21, §§ 26 -53, and 314 CMR 9.00, the Department has determined there is reasonable assurance the project or activity will be conducted in a manner which will not violate applicable water quality standards (314 CMR 4.00) and other applicable requirements of state law. The waters of Willow Pond are designated in the Massachusetts Surface Water Quality Standards as Class B. Such waters are intended "as habitat for fish, other aquatic life and wildlife and for primary and secondary contact recreation." Anti - degradation provisions of these Standards require that "existing uses and the level of water. quality necessary to protect the J existing uses shall be maintained and protected." Background: Frank Newhall Look Park is located at 300 North Main Street in the city of Northampton. The park was deeded to the City in 1928 by Mrs. Fanny Burr Look for the development of a memorial tribute to her late husband Frank Newall Look. Current annual visitor attendance at the Park is estimated to be a half million people. One of the centerpieces of Look Park is Willow Pond, which has walking_trails around -the perimeter and paddle boats for recreation. Willow Pond, formerly known as Willow Lake,. approximately 15 acres in size, was created in the 1930's. The pond is fed by a man -made This information is available in alternate format. Call Michelle Waters - Ekanem, Diversity Director, at 617- 292 -5751. TDD# 1-866-6: 9-7622 or 1.617 -574 -6868 MassDEP Website: www.mass.gov /dep Printed on Recycled Paper 401 Water Quality Certification, Willow Pond at Look Park, Northampton Transmittal Ns: X236227 Page 2 of 7 diversion of the Mill River, which is regulated by a gate valve located on the river's bank. Over time, sediment has accumulated at the bottom, making the water depth in the pond shallower with each successive year. The sediment buildup has restricted access to paddle boats, restricting the recreational use. Proposed proiect This project entails conducting improvement dredging to remove approximately 7,500 yd of sediment from Willow Pond. Although dredging of Willow Pond was done in 1984, the City was unable to provide a copy of the permit for the dredging. Therefore, the proposed dredging is deemed as improvement and not maintenance dredging in accordance with regulatory definition of maintenance dredging in 314 CMR 9.02. Dredging will be conducted in the dry. The gate valve that regulates the flow into the pond will be closed and the water in the pond will be allowed to drain out of the pond. Any remaining water will be pumped out downstream. During drawdown, volunteers under the supervision of both park and the conservation agent will collect all animal and fish species within the pond and transfer them downstream. Once the pond is adequately drained, the sediment will be mechanically dredged from the pond using conventional equipment such as a backhoe. The dredged material will be placed into a dump truck qnd' ransp v6d`to t�e two °proposed storage area (primary and secondary) within the park. Both, areas: arei previously disturbed sites". One was a construction area and the other was %use the 1984 dredging operations. Alternativ &Evaluation: Several alternatives were evaluated for this project which included the following: 1. No�A etifl t � 4ad.'. 2. Hydraulic Dredging 3. Mechanical Dredging in the dry 4. Bio- stabilization for bank protection 5. Re- armoring of the bank 6. Combination of Bio - stabilization /rip rap /Gabion Wall* Under the No Action Alternative, sediment will continue to accumulate making the pond shallower each successive year. Additional sediment accretion will further restrict access of the paddle boats, which is the primary usage of the pond. Dredging cannot be avoided if the pond is to be restored back to the 1984 depth. The west side of Willow Pond, which receives foot traffic from park visitors, has been vandalized over the last several years. The current slope is an earthen embankment armored with 12 -18 inch stones. The armor stones have been dislodged from the surface and thrown into the pond leaving the earthen embankment unprotected. The embankments have eroded in several areas and contributed to sediment accretion in Willow Pond. The preferred alternatives are mechanical dredging in the dry and combination of bio- stabilization /rip rap /gabion wall. The combination of bio- stabilization /rip rap /gabion wall will provide stabilization for the bank, aesthetics, prevention of erosion, access for the public, habitat for wildlife and prevention of bank vandalism. Dredged Material DeWgIgrinc L Although the sediment will be removed in a relatively dry condition after the drawdown of Willow Pond, there will be considerable amount of moisture Page 3 of 7 remaining in the sediment: The dredged material will be further dewatered by gravity and evaporation in the storage areas. Sediment sampling data Seven samples were collected within the proposed dredge area on .May 10, 2010. Three of the sample, Sed -1, Sed -2 and Sed -3 were analyzed for-grain-size distribution and the chemical parameters listed in 314 CMR 9.07(2)(b)6. The remaining samples, Sed -5 thru Sed -8 were only analyzed for metals and Polynuclear Aromatic Hydrocarbons (PAHs). In addition, the seven.samples did not meet the one per 1,000 yd frequency since the proposed dredge volume is 7,500 yd Results of the grain -size distribution showed that the sediment in the samples contained 17.2 percent, 28.3 percent and 78.8 percent of particles passing the No. 200 U.S. Standard Series Testing Sieve. Results of the chemical analysis confirriied the presence of metals and Polynuclear Aromatic - Hydrocarbons (PAHs)(in Sample no. 3 only). With the exception of Nickel in Sample no..2, all detected concentrations were below the Reportable Concentration (RC) S -1 criteria o_ f the Massachusetts Contingency Plan (MCP). On July 1, 2011, five samples were collected from Willow Pond to supplement the grain -size distribution and chemical testing of the May 10, 201.0 sampling event. Results of the grain -size distribution analysis showed that with the exception of sample no. 5 sediment in. all the samples contained more than 10 percent of particles passing the 200 U:S. Standard Series Testing Sieve. For Sample no. 5, 7.4 percent of the sediment passed the S. U.S. Standard Series Testing Sieve. Results of the chemical analysis confirmed the presence of herbicides. All detected concentrations, were below RC -S1. The detected concentrations of Nickel in Sample No. 2 20 mg /kg, The upper limit of S1 /GW1 soil standard for Nickel is 20 mg /kg. Therefore, the sediment represented by sample no. 2 is within the S1 soil standard in accordance with 314 CMR 9.07(9)(b). No further action will be required. Beneficial Reuse of sediments: The dredged material will be reused as construction material to. form the base of the proposed athletic fields. Any excess material will be .moved to the Secondary Sediment Storage Site, which is going to be a Family Recreation Area. Rare Species and Rare Wildlife Habitat: The site is not located within the Priority Habitats of Rare Species, Estimated Habitats. of Rare Wildlife, and Certified Vernal Pool in accordance with the Massachusetts Natural Heritage Atlas, 13 Edition. Public Notice: The 401 WQC application public notice was published in the Daily Hampshire Gazette on March 2, 2011 and the Department received no comment during the 21 -day public comment period, which ended on March 22, 2011. Therefore,_ based on information currently -in the record, the Department -grants- 401 - - - - -- Water Quality Certification for this project subject to the following conditions to maintain water quality, to minimize impact on waters and wetlands, and to ensure compliance with 401 Water Quality Certification, Willow Pond at Look Park, Northampton Transmittal Ns: X236227 Page 4 of 7 appropriate state law.
