ATTACHMENT A – PROJECT NARRATIVE 1.0 Introduction Epsilon Associates, Inc. (Epsilon) submits this Notice of Intent (NOI) to the Barnstable Conservation Commission on behalf of The Town of Barnstable (the Applicant or the Town). The Town partnered with the United States Department of Agriculture Natural Resources Conservation Service and Cape Cod Conservation District to design and install fish passage improvements in the Centerville River at the outlet on the south side of Long Pond in Banstable, MA (the Site). The proposed fish passage installation is described in this NOI. The NOI was prepared and is submitted in accordance with the Massachusetts Wetlands Protection Act (M.G.L. c.131, §40) [WPA] and implementing Regulations (310 CMR 10.00), and the Barnstable Wetlands Protection Bylaw (§237-1 through 14), approved December 1987 and updated July 2003. The Applicant seeks an Order of Conditions (OOC) from the Barnstable Conservation Commission to install the proposed fish passage comprised of a reinforced concrete weir with flashboards, including bolder and vegetation reinforcement to tie into the natural ground, log revetments anchored in the soil at the toe of the bank, and rounded river stone with an associated rock weir downstream of the concrete weir. This will involve work on Inland Bank. This narrative provides a description of the Site and its natural resources, a summary of the proposed activities, and how the proposed work complies with the performance standards in the WPA Regulations and the Barnstable Wetlands Protection Bylaw. 1.1 Purpose and Need The Centerville River is an important diadromous fish passageway in Cape Cod, providing passage for River Herring and American eel from Centerville Harbor north to Long Pond, a waterbody that is over 50 acres. Further north of Long Pond lies Wequaquet Lake, a waterbody that is over 600 acres and is one of the largest bodies of water on the Cape. Both waterbodies are prime River Herring spawning and nursery habitat. In recent years, the Centerville River hosted herring run sizes of 200,000+ in 2021 to 7,000+ in 2023.1 Similar in size to Waquequet Lake, the slightly larger Mashpee Pond and Long Pond Harwich, host average herring runs of 180,000 and 80,000 fish over the past 10-15 years, respectively. Therefore, improving passage into Long Pond and thus Waquaquet Lake will provide a consistent opportunity for annual herring run sizes to reach approximately 80,000 to 180,000 fish. The flow in the Long Pond outlet is restricted by sediment due to shoaling and erosion which results in reduced water depths both in the pond and the outlet that impact fish passage. The Town currently manages water flow in the outlet channel with sandbags. Managing flow with the replacement fish 1 Association to Protect Cape Cod (APCC) & Massachusetts Bays National Estuary Partnership, Cape Cod Region (MassBays), 2023: https://apcc.org/wp-content/uploads/2023/11/Cape-Cod-Herring-Run-Summary-2007- 2023-Final.pdf 25-0633/Long Pond Fish Passage 2 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. passage concrete weir and board system will ensure positive flow and allow fine-tuned flow adjustments that will result in more effective diadromous fish passage to Long Pond and up to Wequaquet Lake. 1.2 Environmental Review The Town of Barnstable anticipates that the proposed improvements will require the issuance of permits and authorizations in the form of: • An Order of Conditions from the Barnstable Conservation Commission by filing of a Notice of Intent (the subject of this filing) including submission of the NOI to the Massachusetts Division of Marine Fisheries (DMF). • A Fishway Construction Permit from the Massachusetts Division of Marine Fisheries, obtained by consolation with DMF including submitting detailed plans of the proposed fish passage structure. • Authorization under Section 404 of the Clean Water Act from the US Army Corps of Engineers (USACE) under Nationwide Permit #60 – Activities to Improve Passage of Fish and Other Aquatic Organisms. 1.3 Limited Project Status This project qualifies as an Ecological Restoration Limited Project under 10.24(8)(e)(3). However, the Applicant has chosen not to file as a limited project as the proposed project meets all performance standards, as demonstrated in Section 4.0. 2.0 Existing Conditions The site of the proposed project is located in the Long Pond outlet segment of the Centerville River, a man-made, stream that flows south from Long Pond along the southern shore at 125 Blantyre Avenue and 93 Holy Lane (see Figure 1 – USGS Locus Map and Figure 2 – Aerial Locus Map.) The outlet segment where the project is proposed is shown as perennial on the USGS map although the water does not flow continuously throughout the year and is considered as an intermittent stream (see Attachment C – Wetland Delineation Report.) The Centerville River flows into the larger Herring River and eventually into East Bay and Centerville Harbor. The Town currently manages an outlet control structure at the mouth of the Long Pond outlet in the form of sandbags placed in the riverbed to control flow (see Attachment G, Sheet 7). The proposed project is located in Massachusetts Natural Heritage and Endangered Species Program (NHESP) Priority Habitat. 2.1 Wetland Resource Areas Areas defined under the Wetlands Protection Act Regulations as wetland resource areas that are within the vicinity of the project area are described below. Work is proposed in Inland Bank which is also designated as a Fish Run, as shown on Figure 3 and in the Project Plans in Attachment G. A detailed wetland delineation was performed in June 2026 by Ilex Environmental. The associated Wetland Delineation Report is provided in Attachment C. 25-0633/Long Pond Fish Passage 3 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. 2.1.1 Land Under Water Bodies and Waterways As defined in 310 CMR 10.56, LUW is “the land beneath any creek, river, stream, pond, or lake. Said land may be composed of organic muck or peat, fine sediments, rocks, or bedrock.” LUW is present beneath Long Pond, just north of the proposed project. There is no LUW associated with the Centerville River, as the stream is an intermittent stream, therefore during no flow conditions there is no LUW. Thus, the entire cross-section is regulated Inland Bank. The intermittent streambed is at approximately 24.9 feet in elevation, which is higher in elevation than the mean annual low water level (el. 24.0). See Attachment C – Wetland Delineation Report for details. 2.1.2 Inland Bank As defined in 310 CMR 10.54, Inland Bank is “… the portion of the land surface which normally abuts and confines a waterbody. It occurs between a water body and a vegetated bordering wetland and adjacent floodplain, or, in the absence of these, it occurs between a water body and an upland.” A 100-foot buffer zone is associated with Inland Bank. The Top of Bank is depicted on Figure 3 and on the Project Plans in Attachment G, and the Toe of Bank is depicted on the Project Plans in Attachment G. The Top of Bank and Toe of Bank lines were informed by a topographic survey performed by the Town on December 29, 2022, and are described in the Wetland Delineation Report in Attachment C. Because the Centerville River does not have Land Under Water, the entire channel cross-section between the two bank lines is regulated as Inland Bank. The Inland Bank is comprised of steep slopes vegetated with a mix of upland and wetland vegetation. Additionally, Inland Bank associated with Long Pond is located north of the project area. 2.1.3 Fish Run As defined in 310 CMR 10.35, Banks of or Land under the Ocean, Ponds, Streams, Rivers, Lakes, or Creeks that Underlie an Anadromous/Catadromous Fish Run (Fish Run) is “that area within estuaries, ponds, streams, creeks, rivers, lakes or coastal waters, which is a spawning or feeding ground or passageway for anadromous or catadromous fish and which is identified by the Division of Marine Fisheries or has been mapped on the Coastal Atlas of the Coastal Zone Management Program. Such fish runs shall include those areas which have historically served as fish runs and are either being restored or are planned to be restored at the time the Notice of Intent is filed. For the purposes of 310 CMR 10.21 through 10.37, such fish runs shall extend inland no further than the inland boundary of the coastal zone.” The Inland Bank within the project area falls under the definition of a fish run, as identified by DMF. 2.2 Rare Species Habitat The Natural Heritage and Endangered Species Program Estimated and Priority Habitat of Rare and Endangered Species mapping shows priority habitats for State-listed species (PH 253) within Long Pond and the surrounding area, including the majority of the project site. Estimated Habitat of Rare Wildlife is not mapped in the project or surrounding area. 25-0633/Long Pond Fish Passage 4 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. 3.0 Project Description The project proposes to install a fish passage improvement structure comprised of a reinforced concrete weir with flashboards, including bolder and vegetation reinforcement to tie into the natural ground, log revetments anchored in the soil at the toe of the bank, and rounded river stone with an associated rock weir downstream of the concrete weir. The proposed project work area is approximately 7,150 sf, as shown on Sheet 6 of the Project Plans in Attachment G. This is inclusive of the staging area off of Holly Lane. There is limited site access off of Holly Lane, through 125 Blantyre Avenue on the eastern side of the weir installation. The proposed construction timeframe is in the Summer of 2027. Proposed work will be completed in accordance with all environmental permits and Time of Year restrictions. No construction is planned to occur during spring (February 1st and June 1st) and fall (September 1st to November 1st) in accordance with time of year (TOY) restrictions for river herring, American eel, and white perch that are anticipated to be recommended by DMF. Construction will begin with the dewatering of the project area. Construction will occur during a period when the stream is dry, either from seasonal low water levels, or by the Town controlling outlet flows from Wequaquet Lake into Long Pond. The existing sandbag water control structure may also be used to block flow into the southern Centerville River from Long Pond. After the work area is dewatered, erosion and sedimentation controls will be installed. A dewatering filter bag will be used for all groundwater dewatering, as detailed on Sheet 6 of the Project Plans in Attachment G. Filter bags will be replaced when they become half full of sediment. Proposed sediment controls include 8-inch diameter compost filter socks, staked every 10 feet on center, as detailed on Sheet 6 of the Project Plans in Attachment G. These sediment barriers will be installed around excavation material stockpiles and disturbed areas upgradient of Long Pond. Large trees within the work area will be protected. Where feasible, existing trees within the work area will have tree protection fencing installed 8-feet from the trunk. In areas proximate to the limits of work where fencing 8-feet from the trunk of trees is not feasible, tree armor will be used. Once the site is dry and erosion and sediment controls are in place, approximately 70 cubic yards of material will be excavated from a 340 square foot area to install the concrete weir. The concrete forms will be placed to construct the weir footing, rebar will be installed within the form and concrete poured to construct the concrete reinforced weir. Once the concrete is poured and has cured for several days, the form will be removed and the area around the weir backfilled to match pre-construction grades. Stainless steel flashboard channels will also be installed in the concrete. See Sheet 4 of the Project Plans in Attachment G for details on the concrete weir. Afte the concrete weir is installed, downstream scour protection will be placed in the channel. Scour protection as designed includes 15 feet of 4-inch round river stone at a thickness of 8-inches, overlain by a layer of gravel to fill stone voids. A stone weir will be installed to transition from the river stone to the natural stream bed, as detailed on Sheet 3 of the Project Plans in Attachment G. Stone and vegetation 25-0633/Long Pond Fish Passage 5 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. reinforced soil will be installed to transition the concrete weir to the existing soil bank. This treatment will extend 2 feet above the Top of Inland Bank. Scour protection for the Toe of Bank will be completed by anchoring 18-inch diameter logs of sound straight un-splintered white oak, eastern red cedar or an approved equivalent species into the toe of bank using wraps of cable or wire, as detailed on Sheet 5 of the Project Plans in Attachment G. Alternatively, boulders will be used to stabilize the toe in areas where existing tree rootzones extend into the bank toe and removal of the tree is not practical. Finish grading, planting, and seeding of the work area will be completed before demobilization. Disturbed Inland Bank will be revegetated with shrubs planted 3-feet on-center. Areas between the shrubs will be revegetated by sowing a native grass/forb seed mix and covered with a biodegradable matting such as jute netting to provide temporary stabilization until the seed germinates and vegetation establishes a root matrix to stabilize soils. 4.0 Regulatory Compliance The project was designed to avoid, minimize, and mitigate wetland resource area alterations to the extent practicable. As discussed above, proposed activities will be conducted within Inland Bank, Fish Runs, and in the 100-foot Buffer Zone to Bank. 4.1 Compliance with the WPA According to the WPA Regulations, on-site wetland resource areas are significant to the applicable interests oi the WPA: flood control, storm damage prevention, prevention of pollution, wildlife habitat, fisheries habitat, protection of public and private water supply, and protection of groundwater supply. Compliance with specific performance standards are addressed below. 4.1.1 Inland Bank Work in Inland Bank involves installation of the concrete weir structure, bank restoration, installation of log revetment toe protection, and installation of rounded river stone scour protection. 310 CMR 10.54(4)(a) reads as follows: “Where the presumption set forth in 310 CMR 10.54(3) is not overcome, 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; 25-0633/Long Pond Fish Passage 6 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. 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. In the case of a bank of a river or an intermittent stream, the impact shall be measured on each side of the stream or river. 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. 6. Work on a stream crossing shall be presumed to meet the performance standard set forth in 310 CMR 10.54(4)(a) provided the work is performed in compliance with the Massachusetts Stream Crossing Standards by consisting of a span or embedded culvert in which, at a minimum, the bottom of a span structure or the upper surface of an embedded culvert is above the elevation of the top of the bank, and the structure spans the channel width by a minimum of 1.2 times the bankfull width. This presumption is rebuttable and may be overcome by the submittal of credible evidence from a competent source. Notwithstanding the requirement of 310 CMR 10.54(4)(a)5., the impact on bank caused by the installation of a stream crossing is exempt from the requirement to perform a habitat evaluation in accordance with the procedures contained in 310 CMR 10.60.” Project Compliance: 1. The project will not alter the physical stability of the bank, as riprap will be installed at the junction of the concrete weir and logs will be anchored north and south of the concrete weir at the Toe of Bank to stabilize the bank. 2. The weir structure will in part serve to allow the Town greater flow or water level control as needed to improve fish passage, but will not impair the carrying capacity of the channel. 3. Temporary impacts to surface water quality will be minimized by performing in-water work in dry conditions. The project will not alter groundwater quality. 4. The project will not alter the capacity of the Bank to provide breeding habitat, escape cover and food for fisheries; 5. The project will alter approximately 58 ft of Bank, therefore a Simplified Wildlife Habitat Evaluation was performed and is included in Attachment D. The Simplified Wildlife Habitat Evaluation did not identify impacts to wildlife habitat, and NHESP MESA review will inform on potential wildlife habitat impacts. Due to the existing water control structure and small footprint of the proposed replacement structure, the project will not impact the Bank’s capacity to provide wildlife habitat functions. 6. The project does not involve work on a stream crossing. 310 CMR 10.54(4)(b) – Performance Standard 25-0633/Long Pond Fish Passage 7 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. “Notwithstanding the provisions of 310 CMR 10.54(4)(a), structures may be permitted in or on a Bank when required to prevent flood damage to facilities, buildings and roads constructed prior to the effective date of 310 CMR 10.51 through 10.60 or constructed pursuant to a Notice of Intent filed prior to the effective date of 310 CMR 10.51 through 10.60 (April 1, 1983), including the renovation or reconstruction (but not substantial enlargement) of such facilities, buildings and roads, provided that the following requirements are met: 1. The proposed protective structure, renovation or reconstruction is designed and constructed using best practical measures so as to minimize adverse effects on the characteristics and functions of the resource area; 2. The applicant demonstrates that there is no reasonable method of protecting, renovating or rebuilding the facility in question other than the one proposed.” Project Compliance: Not Applicable. The proposed project is not a flood control project to protect damage to buildings, facilities, and roads. 310 CMR 10.54(4)(c) – Performance Standard “Notwithstanding the provisions of 310 CMR 10.54(4)(a) or (b), no project may be permitted which will have any adverse effect on specified habitat sites of Rare Species, as identified by procedures established under 310 CMR 10.59.” Project Compliance: The project is located within priority habitat (PH 253). Accordingly, a copy of this NOI is being submitted to NHESP for joint MESA review. 4.1.2 Fish Runs 310 CMR 10.35(3) – Performance Standard “Any project on such land or bank shall not have an adverse effect on the anadromous or catadromous fish run by: (a) impeding or obstructing the migration of the fish, unless DMF has determined that such impeding or obstructing is acceptable, pursuant to its authority under M.G.L. c. 130, § 19; (b) changing the volume or rate of flow of water within the fish run; or (c) impairing the capacity of spawning or nursery habitats necessary to sustain the various life stages of the fish.” 25-0633/Long Pond Fish Passage 8 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. Project Compliance: The proposed project is designed to improve fish passage, and therefore will not impede or obstruct fish migration. The volume and flow rate of water will be able to be controlled to improve fish passage and as designed will not reduce the volume conveyed through the stream. The project will not effect spawning or nursery habitats. 310 CMR 10.35(4) – Performance Standard “Unless otherwise allowed by DMF pursuant to M.G.L. c. 130, § 19, dredging, disposal of Dredged Material or filling in a fish run shall be prohibited between March 15th and June 15th in any year.” Project Compliance: The proposed project will not involve dredging or disposal of dredged material in a fish run. Approximately 70 cubic yards of material will be excavated to install the concrete weir and that material will be removed for off-site disposal as needed. 310 CMR 10.35(5) – Performance Standard “Notwithstanding the provisions of 310 CMR 10.35(3), no project may be permitted which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified by procedures established under 310 CMR 10.37.” Project Compliance: The project is located within priority habitat (PH 253). Accordingly, a copy of this NOI is being submitted to NHESP for joint MESA review. 310 CMR 10.35(6) – Performance Standard “Any person proposing a new stream crossing of a Fish Run shall demonstrate to the issuing authority that there are no practicable alternatives to the crossing, that the impacts of the crossing have been minimized and that mitigation measures have been provided to contribute to the protection of the interests identified in M.G.L. c. 131, § 40. An applicant will be presumed to have made this showing if the project is designed as follows: (a) If the project includes the construction of a new non-tidal crossing, the applicant demonstrates to the satisfaction of the issuing authority that the crossing complies with the Massachusetts Stream Crossing Standards by consisting of a span or embedded culvert in which, at a minimum, the top of the structure is above the elevation of the top of the bank and the structure spans the channel width by a minimum of 1.2 times the bankfull width. 25-0633/Long Pond Fish Passage 9 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. (b) If the project includes the construction of a new tidal crossing, the applicant demonstrates to the satisfaction of the issuing authority that the project is designed in a manner that does not restrict tidal flow over the full natural tidal range by consisting of a span or embedded culvert in which, at a minimum, the top of the structure is above the elevation of the top of the bank and the structure spans the channel width by a minimum of 1.2 times the bankfull width. This presumption that the impacts of the crossing have been avoided, minimized and that mitigation measures have been provided to contribute to the protection of the interests identified in M.G.L. c. 131, § 40 may be rebutted by credible evidence from a competent source.” Project Compliance: Not Applicable. The project does not propose a stream crossing of a fish run. 4.2 Compliance with the Barnstable Wetlands Regulations The Barnstable Wetland Protection Ordinance promulgates the Town’s performance standards, design specifications, policy guidelines and other rules and regulations (§237-8), and defines these performance standards within the regulation governing activity in the 100-ft buffer zone under Notice of Intent Applications (§704-3). As stated in section §704-6 Applicability, “A. This Regulation shall not be construed to preclude the following activities, any of which may be permitted at the Commission’s discretion, and without accompanying requirement for mitigation planting:... (5) The construction of water dependent facilities as defined in 704-2(F) herein.” §704-2(F) reads, “WATER DEPENDENT FACILITY - is any structure or works associated with water dependent industrial, maritime, recreational, educational, or fisheries activities that must be located at or near the shoreline and within the 100 ft buffer zone. An activity is water dependent if it is dependent on the water as part of the intrinsic nature or function of the operation. Examples of water dependent facilities include ports, marinas, community piers, public beaches, recreational areas and fisheries. Residences, restaurants, restrooms and concession stands are not water dependent.” The proposed project is the installation of a concrete fish weir for the purpose of improving fish passage in the Centerville River, and therefore qualifies as a water dependent facility. Based on this finding and due to the nature of the project, the Applicant requests that the Commission waive the requirement for mitigation planting. Additionally, the project involves revegetating the Bank and construction area as described in Section 6.5. 5.0 Mitigation Measures 5.1 Time of Year Restrictions It is anticipated that Time of Year restrictions for fish passage of river herring and American eel will be recommended by DMF stating that no construction is to occur between February 1st and June 1st, and 25-0633/Long Pond Fish Passage 10 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. between September 1st and November 1st. Therefore, construction of the proposed project will occur between June 2 and August 31 to accommodate these restrictions. If construction cannot be completed within the approved work period, work will be shutdown until after November 1rst. The state of the work site during shutdown shall allow for fish passage during the shutdown, if needed. 5.2 Erosion and Sedimentation Control Measures Erosion and sedimentation control measures will be installed prior to any construction activity. Silt fencing or approved equal sediment barriers will be installed around excavation material stockpiles and around disturbed areas upgradient of Long Pond. Proposed erosion and sediment controls include 8-inch diameter compost filter socks, staked every 10 feet on center, as detailed on Sheet 6 of the Project Plans in Attachment G. All excess excavated material from weir construction and sediment removed from the channel will be disposed of by the contractor off-site according to local, state, and federal regulations. 5.3 Refueling All refueling operations will be conducted within a designated refueling pad in the staging area on the worksite at the end of Holly Lane. The refueling area will be protected by a 4-inch minimum raised berm to prevent run-on/run-off. No refueling will occur within 50 feet of sensitive water bodies or storm drain inlets, however the entirety of the worksite is within the 100-foot buffer to the Top of Bank. In the event of a spill, the operator will immediately close the emergency isolation valve and deploy on-site spill kits. In the event there is an accidental release of petroleum products into a wetland resource area, the Conservation Commission will be notified along with appropriate emergency response agencies. Equipment will be serviced or maintained off-site and kept in a condition that prevents leaks or discharge of pollutants. 5.4 Dewatering Plan The contractor will provide a dewatering plan to the engineer for approval prior to construction. The plan will include an energy dissipation and outlet protection erosion control system. A filter bag outlet system will be used, consisting of a low volume filter bag made from non-woven geotextile material sewn with high strength, double stitched, “J” type seams and be capable of trapping particles larger than 150 microns. Filter bags will be replaced when they become half full of sediment, and a suitable means of accessing the bag with machinery required for disposal purposes will be included in the dewatering plan. Typical details of a pumped dewatering filter bag are provided on Sheet 6 of the Project Plans in Attachment G. 5.5 Existing Condition and Vegetation Conservation & Restoration The contractor will be responsible for any damage to existing plants, including but not limited to landscaping, trees, and the paved areas as designated by the property owner. All damaged vegetation will be restored to their existing condition or better, or replaced at no additional cost to the owner. 25-0633/Long Pond Fish Passage 11 Attachment A – Project Narratives Notice of Intent Epsilon Associates, Inc. Large trees at the mouth of the Centerville River, flagged by an NRCE or CCCD Representative, will be protected from damage during construction. Where feasible, existing trees within the work area will have tree protection fencing installed 8-feet from the trunk of trees with an 8-inch diameter at breast height (DBH) or less. For larger trees, the fencing will be installed at the drip line. In areas proximate to the limits of work where fencing 8-feet from the trunk of trees is not feasible, tree armor may also be required. Tree armor will consist of wooden 2-inch by 4-inch boards butted side-to-side completely around the trunk. Work will be minimized in the root protection zone. Disturbed bank areas will be revegetated with shrubs planted 3-feet on-center. Sweet pepperbush (Clethra aniflora) will comprise 50% of the total shrub plantings, and the remainder will be bayberry (Morella pennsylvanica), button bush (Cephalanthus occidentalis), winterberry (Ilex verticilata), and elderberry (Sambucous canadensis). Areas between the shrubs will be revegetated by sowing a native grass/forb seed mix and mulched with a biodegradable matting such as jute netting to stabilize exposed soils until the seeds germinate and plants develop a root matrix to stabilize soils. 6.0 Conclusion The information contained in this NOI and the attached supporting material sufficiently describes the Site, work in resource areas, and documents compliance with the WPA Regulations and the Barnstable Wetland Regulations. The Applicant therefore respectfully requests that the Barnstable Conservation Commission issue an Order of Conditions approving the proposed project with appropriate conditions to protect the interests identified in M.G.L. c. 131 §40 and the Barnstable Environmental Protection Bylaw.

Yarmouth, MA 02673 Re: Wetland Delineation Report Long Pond Outlet Fish Passage Improvement Project Off Blantyre Avenue and Holy Lane Centerville, Barnstable, Massachusetts Dear Karissa: ILEX Environmental, Inc. (ILEX) is pleased to submit this wetland delineation letter report relative to the wetland resource areas at the Long Pond Outlet in the village of Centerville, Barnstable, Massachusetts. The proposed Long Pond Outlet Fish Passage Improvement Project (the Project) located along the southern shore of Long Pond (see Figure 1) at 125 Blantyre Avenue (Parcel 229108) and 93 Holy Lane (Parcel 229015) (Assessor’s Map 43, Lot 2); both parcels of which are privately owned. The outlet to Long Pond is identified as the Centerville River which is reported to have been a ditch dug circa 1867. This river is shown as perennial on the USGS map although the water does not flow continuously throughout the year and is considered as an intermittent stream for this letter report. The Centerville River is identified by the Massachusetts Division of Marine Fisheries (DMF) as diadromous fish migratory habitat for the river herring (anadromous) and American eel (catadromous). Long Pond is identified as diadromous fish river herring spawning and nursery habitat. The flow to the outlet is restricted by sediment due to shoaling and erosion which results in reduced water depths both in the pond and the outlet impacting fish passage. The Project is proposed to insure positive flow to the outlet and facilitate fish passage through the construction of a concrete weir in the existing ditch to replace the existing sandbags at the outlet channel (see Photos 1 and 2). A field visit was held on March 24, 2026 to identify and delineate (if appropriate) local, state, and federal wetlands at the Project Site. No field delineations were performed as elevations are needed to determine the boundaries of the wetland resource areas as described below. • Bank (Naturally Occurring Banks and Beaches): There are two inland Banks at the site relative to Long Pond and the outlet ditch which is an intermittent stream. Inland banks are defined at 310 CMR 10.54(2)(a) as “…the land surface which normally abuts and confines a water body. It occurs between a water body and a vegetated bordering vegetated wetland and adjacent flood plain, or, in the absence of these, it occurs between a water body and an upland”. In addition, at 310 CMR 10.54(2)(c) “The upper boundary of the Bank is the first observable break in slope or the mean annual flood level, whichever is lower. The lower boundary of the Bank is the mean annual low flow level.” According to information provided Page 2 by the Natural Resources Conservation Service (NRCS), the mean annual flood level of the intermittent stream is approximately 24.9 feet in elevation which delineates the top of the Bank. The two Banks observed include the following: o Bank associated with Intermittent Stream: . As an intermittent stream has no mean annual low flow, the entire resource areas would be identified as Bank (no Land Under Water is present in the intermittent stream). This Banks is comprised of steep slopes vegetated with a mix of upland and wetland vegetation. Work proposed in the outlet ditch includes the construction of the concrete weir. The impact of Bank is presently being estimated based on the latest design plans. o Bank associated with Long Pond: Based on conditions observed during the March 24, 2026 field visit, it appeared that the inland Bank associated with Long Pond is approximately two to three feet high and vegetated with upland and wetland vegetation with remnants of concrete block and sand bags as shown on Photo 1. No impact to the Bank associated with Long Pond is proposed. • Land Under Water Bodies and Waterways: Land Under Water is present beneath Long Pond. The upper boundary of Land Under Water for Long Pond is identified at 310 CMR 10.56(2)(a) as the mean annual low water level. According to the NRCS, the mean annual low water level is approximately 24.0 feet in elevation. Long Pond is approximately 50 acres in size therefore, meets the definition of a Great Pond. No work associated with the construction of the proposed weir is proposed in Land Under Water. Future plans will identify erosion and sedimentation controls which may be placed within Land Under Water during construction. There is no Land Under Water resource area associated with the intermittent stream. As the upper boundary of land under water is defined as the mean annual low water level (24.0 feet in elevation), an intermittent stream would be higher in elevation and dry under the annual low water condition, therefore no delineation of Land Under Water is possible. Therefore, there would be no impact of Land Under Water for any work in the outlet ditch. Any excavation of this outlet ditch, if required, would not be defined as dredging but alteration of Bank. • Bordering Vegetated Wetlands: No bordering vegetated wetlands are located at the Project site; instead the area is comprised of Land Under Water and inland Bank associated with Long Pond which is vegetated with both upland and wetland vegetation. Therefore, no vegetated wetlands will be impacted as part of this Project. • Bordering Land Subject to Flooding: There are no mapped 100-year flood plains (of 1% annual chance of occurrence) in or near the Project as shown on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) on Figure 2. Zone X is mapped for Long Pond which is considered as having a 0.2% chance of occurrence. Therefore, the Bordering Land Subject to Flooding at this Site as defined by 310 CMR 10.57(2)(a)3. is considered to be the “…maximum lateral extent of flood water which has Page 3 been observed or recorded”. Work within this resource area may include the installation of the concrete weir. As assessment of flood plain impacts will be prepared once the design plans are finalized. The proposed work will not affect the hydraulic capacity of the existing ditch as the weir is designed to allow flows out of Long Pond, therefore, there are no changes to the downstream floodplain. • Riverfront Area: The outlet ditch is identified on some maps as the Centerville River. Although the USGS map identifies this ditch as perennial, the ditch dries up annually and would not meet the definition of a perennial river, therefore, there is no Riverfront Area associated with this ditch. • Estimated Habitats of Rare Wildlife: According to the 15th Edition Heritage Atlas prepared by the Massachusetts Heritage and Endangered Species Program (NHESP), effective August 1, 2021, the Project is not located within mapped as Estimated Habitat as shown on Figure 3. No certified or potential vernal pools are mapped in or near to the Project site. Nonetheless, the Project is located within mapped Priority Habitat (PH 253), therefore, coordination and a potential filing with NHESP pursuant to the Massachusetts Endangered Species Act (MESA) is required. • Banks of or Land Under Ponds, Streams, or Rivers that Underlie Anadromous and/or Catadromous Fish Runs: Although the Project site is not located in or near any coastal wetland resource areas, it is located within the Massachusetts Coastal Zone. Therefore, the inland Bank and Land Under Water resource areas (as described above) fall under this definition of a fish run in accordance with 310 CMR 10.35.

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

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