Home My WebLink About20260825 NOI Town of Barnstable Long Pond Area Sewer Expansion Project 2 ectinc.com Attachment D: Wetland Reports January 28, 2021 Email (mviolette@nitscheng.com) Mr. Denis Seguin, PLS Nitsch Engineering 2 Center Plaza, Suite 430 Boston, MA 02108 Re: Wetland Resource Area Analysis Report [LEC File #: NEI\20-113.01] Long Pond Sewer Extension Project Centerville, Massachusetts Dear Mr. Seguin: As requested, LEC Environmental Consultants, Inc., (LEC) conducted a site evaluation and Wetland Resource Area Analysis for the Long Pond Sewer Extension Project located in Barnstable (Centerville), Massachusetts. The purpose of the evaluation was to determine Wetland Resource Area boundaries within the project area, as depicted on the attached Figure 1: Project Area, prepared by the Town of Barnstable Wastewater Resources Advisory Committee (WRAC) (Attachment A). Specifically, LEC delineated the boundaries of protectable Wetland Resource Areas within 50 feet of the public right-of- ways within the project area and approximated Wetland Resource Area boundaries located beyond 50 feet based on field observations and the MassGIS Wetlands Datalayers. The delineated and approximated Wetland Resource Area boundaries are depicted on the Massachusetts Department of Transportation Plan of Topographic Survey of Long Pond Sewer Expansion Plans (“plans”), prepared by Nitsch Engineering, dated January 7, 2021 (provided under separate cover by Nitsch Engineering). The evaluation was conducted in accordance with the Massachusetts Wetlands Protection Act (“WPA”, M.G.L. c. 131, s. 40) and its implementing Regulations (310 CMR 10.00), the Town of Barnstable Wetlands Protection Bylaw (Chapter 237) and its implementing Regulations, and the Federal Clean Water Act (“CWA”; 33 U.S.C. 1344, s. 404) and its Regulations (33 CFR and 40 CFR). LEC also employed the criteria provided in Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act (March 1995) and Field Indicators for Identifying Hydric Soils in New England (Version 4, June 2018). The following report provides a general site description, wetland delineation methodology, a description of the Wetland Resource Areas, and potential regulatory implications: Page 2 of 10 General Site Description The project area (herein referred to as “the site”) is situated generally south of Falmouth Road (Route 28), east of Old Stage Road/Park Avenue, north of the intersection of Church Hill Road and South Main Street, and west of Strawberry Hill Road in south-central Barnstable (Centerville), Massachusetts (Attachment A, Figure 1 & Attachment B, Figures 1 & 2). The site includes the following paved public roadways and areas within 100-feet: Old Stage Road, Main Street, Park Avenue, Maple Avenue, Linden Avenue, Wilton Drive, Briar Cliff Lane, Joyce Anne Road, Old Post Road, Malory Road, Phinneys Lane, Sachem Drive, Long Pond Circle, Quiet Way, Piney Point Drive, Partridge Way, Pheasant Way, Stanley Way, Dunaskin Road, Blantyre Avenue, Holly Lane, Pond View Drive, Herring Run Drive, Horatio Lane, Childs Street, Kennesaw Avenue, Bee Lane, Riverview Lane, Maureen Road, Joan Road, Katherine Road, Beth-Ann Lane, Trinity Place, and Alberti Way. The paved public roadways are typically bordered by residential development with associated paved driveways and manicured landscaping features. Additionally, a cemetery, forested uplands, vegetated public spaces, paved sidewalks, Bordering Vegetated Wetlands (BVW), Salt Marsh, intermittent streams, perennial streams, and Long Pond are located along the roadways in the project footprint. Topography throughout the site is undulating, generally sloping downgradient towards the aforementioned Wetland Resource Areas from the developed areas located on topographically high points of the landscape. Vegetation within the upland areas immediately adjacent to the right-of-ways is generally comprised of landscaped mature trees, saplings, shrubs, and manicured lawn. According to the Natural Resource Conservation Service (NRCS) Soil Survey (Web Soil Survey Barnstable County, Massachusetts, Version 16, September 12, 2019), the upland portions of the site are mapped as Carver coarse sands (0 – 35% slopes) and Eastchop loamy fine sand (0 – 3% slopes). NRCS describes the Carver Series as very deep, excessively drained sandy soils formed in glaciofluvial deposits of coarse and very coarse sands, and the Eastchop Series as very deep, excessively drained soils formed in sandy glacial outwash formed on moraines and outwash plains. LEC’s field observations of the soil profile were generally inconsistent with the NRCS Soil Survey, as upland soils typically exhibited some level of anthropogenic disturbance (i.e., fill layers and/or rocky conditions restricting soil observations) considering the proximity to development. Natural Heritage and Endangered Species Program Designation According to the 14th Edition of the Massachusetts Natural Heritage Atlas (effective August 1, 2017) published by the Natural Heritage & Endangered Species Program (NHESP), Long Pond and the adjacent surrounding land is mapped as Priority Habitat of Rare Species (PH #264). The remainder of the site is not located within or in proximity to a Priority Habitat of Rare Species or Estimated Habitat of Rare Wildlife. No Certified Vernal Pools (CVP) or Potential Vernal Pools (PVP) are mapped on or within the immediate vicinity of the site (Attachment B, Figure 2). Page 3 of 7 Floodplain Designation According to the July 16, 2014 FEMA Flood Insurance Rate Maps (FEMA FIRM) for Town of Barnstable (Community Panels 25001 C 0563J, 25001 C 0564J, and 25001 C 0564J), the site is mapped within a Zone X (unshaded) – Areas outside the 1% annual chance flood (Attachment A, Figure 4). Small portions of Pheasant Way and Katherine Road located within the southern portion of the site are mapped within a Zone AE (el. 13) – Special Flood Hazard Areas subject to inundation by the 1% annual chance flood (Base Flood Elevation determined) and a Zone X (shaded) – Areas of 0.2% annual chance flood; areas of 1% annual chance flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 1% annual chance flood. The entire Long Pond and adjacent areas are also mapped within a Zone X (shaded). As a result, the portion of the site beyond any protectable Wetland Resource Area boundaries (i.e., BVW, Bank, and Salt Marsh) mapped within a Zone AE is located within Land Subject to Coastal Storm Flowage (LSCSF). Wetland Boundary Determination Methodology On September 3, 2020, LEC conducted a site evaluation to identify and characterize existing protectable Wetland Resource Areas located within 50 feet of the right-of-ways within the site. LEC observed the approximate boundaries to Wetland Resource Areas located beyond 50 feet of the right-of-ways through visual observation from the right-of-way during the site evaluation and utilization of the MassGIS Wetlands Datalayer. The BVW boundaries were determined through observations of the existing plant communities, using the "fifty percent criteria" to determine dominance of wetland/upland vegetation, the interpretation of soil characteristics, and other indicators of wetland hydrology in accordance with the Massachusetts Department of Environmental Protection (MADEP) handbook, Delineating Bordering Vegetated Wetlands under the Massachusetts Wetlands Protection Act (March 1995), the Field Indicators for Identifying Hydric Soils in New England (Version 4, May, 2018), the Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and Northeastern Region, and the criteria set forth in 310 CMR 10.55. The BVW boundaries were demarcated in the field with blaze orange surveyor’s flagging tape, embossed with the words “LEC Resource Area Boundary” in bold, black print and/or orange stick-in flagging numbered C1 – C6, D1 – D6, E1 – E7, and F1 – F6 (Sheets 26, 27, 28, 30, and 44 of the plans). The Salt Marsh boundaries were demarcated in the field with blaze orange surveyor’s flagging tape, embossed with the words “LEC Resource Area Boundary” in bold, black print and/or orange stick-in flagging in accordance with 310 CMR 10.23 and are numbered A1 – A6 and B1 – B5 (Sheets 53 and 75 - 77 of the plans). The Bank line associated with Long Pond was delineated with blue flagging in accordance with the criteria set forth in 310 CMR 10.54. Bank flags are numbered Bank B1 – Bank B2. The Bank/Mean Annual High Water (MAHW) line associated with the perennial stream discharging from Long Pond was delineated with Page 4 of 7 blue flagging tape in accordance with the criteria set forth in 310 CMR 10.54 and 10.58. Bank/MAHW flags are numbered Bank A1 – Bank A12 (Sheet 55 of the plans). The approximate boundaries of delineated Wetland Resource Areas are depicted on the attached Wetland Delineation Sketch, prepared by LEC, dated September 3, 2020 (Attachment B). Wetland Resource Areas Wetland Resource Areas associated with the site include Bordering Vegetated Wetland (BVW), Salt Marsh, Bank, Bank/Mean Annual High Water (MAHW), Land Under Waterbodies and Waterways (LUW), Riverfront Area, and Land Subject to Coastal Storm Flowage (LSCSF). A brief description of the Wetland Resource Areas is provided below. Bordering Vegetated Wetland (BVW) BVW is defined at 310 CMR 10.55(2) as freshwater wetlands which border on creeks, rivers, streams, ponds, and lakes…Bordering Vegetated Wetlands are areas where the soils are saturated and/or inundated such that they support a predominance of wetland indicator plants…The boundary of Bordering Vegetated Wetlands is the line within which 50% or more of the vegetational community consists of wetland indicator plants and saturated or inundated conditions exist. Two BVWs are situated within the western portion of the site in proximity to Main Street and Briarcliff Lane. The C, E, and F-series wetland flags are associated with the portions of a large BVW that extends within 50 feet of the right-of-way. Typically, topography steeply descends from the right-of-way towards the BVW boundaries and is generally flat within the BVW. The BVW is characterized as a scrub/shrub- forested wetland and held pockets of standing water at the time of LECs site evaluation. Vegetation within the C, E, and F-series BVW includes a moderately dense canopy layer of red maple (Acer rubrum), American elm (Ulmus americana), and willow (Salix sp.). The moderately dense understory contains saplings from the overstory; a shrub layer of scattered individuals of sweet pepperbush (Clethra alnifolia), highbush blueberry (Vaccinium corymbosum), spice-bush (Lindera benzoin), arrowwood (Viburnum dentatum), and multiflora rose (Rosa multiflora); and a groundcover layer of cinnamon fern (Osmunda cinnamomea), sensitive fern (Onocleus sensibilis), various rushes (Carex spp.), sphagnum moss (Sphagnum sp.), and seedlings from the overstory. Patches of entanglements of grape vine (Vitis sp.), poison ivy (Toxicodendron radicans), and common greenbrier (Smilax rotundifolia) are present throughout. The D-series wetland flags are associated with a small depression located within the southern portion of Mother’s Park that is connected to the C-series segment of the above-referenced BVW via a culvert located beneath Main Street. At the time of LEC’s site evaluation, standing water was observed at the inlet of the aforementioned culvert located between wetland flags D2 and D3 and appears to discharge to the C-series wetland during rain events and at times of high groundwater elevations. The observed BVW boundaries located beyond 50 feet of the right-of-ways are associated with the C, E, and F-series BVW and are generally consistent with the DEP Wetland Datalayer (i.e., no additional Page 5 of 7 wetlands are present within the survey area). Vegetation within this BVW lacks a distinct canopy layer, and is dominated by a shrub layer of silky dogwood (Cornus amomum), highbush blueberry (Vaccinium corymbosum), and arrowwood (Viburnum dentatum). Groundcover includes sensitive fern (Onocleus sensibilis), various grasses (Gramineae spp.), sedges (Carex spp.), sphagnum moss (Sphagnum sp.), and seedlings from the shrub layer. According to the NRCS Soil Survey (Web Soil Survey Barnstable County, Massachusetts, Version 16, September 12, 2019), the BVWs are mapped as Freetown and Swansea Mucks, Ipswich – Pawcatuck – Matunuck Complex (0 – 2% slopes), and Freetown coarse sand (0 – 3% slopes). NRCS describes the Freetown and Swansea Muck Series’ as very deep, very poorly drained organic soils formed in highly decomposed organic materials in depressions or on level uplands and alluvial plains, the Ipswich – Pawcatuck –Matunuck Complex as very deep, level, very poorly drained soils in tidal areas, and the Freetown sandy Series as very deep, level, very poorly drained soil in outwash plains, on moraines, and in areas of glacial lake deposits along streams, ponds, and lakes. Generally, test pits were consistent with the soil surveys and observed soil profiles are considered ‘hydric’ in accordance with the Field Indicators Guide and meet the criteria for F6: Redox Dark Surface, A2: Histic Epipedon, and/or A11: Depleted Below Dark Surface. Salt Marsh Salt Marsh is defined at 310 CMR 10.23(2)(a) as a coastal wetland that extends landward up to the highest high tide line, that is, the highest spring tide of the year, and is characterized by plants that are well adapted to or prefer living in, saline soils. Dominant plants within salt marshes typically include salt meadow cord grass (Spartina patens) and/or salt marsh cord grass (Spartina alterniflora), but may also include, without limitation, spike grass (Distichlis spicata), high-tide bush (Iva frutescens), black grass (Juncus gerardii), and common reedgrass (Phragmites). A salt marsh may contain tidal creeks, ditches and pools. Salt Marsh (A and B-series wetland flags) is associated with the perennial Centerville River. The Salt Marsh is a flood-prone, brackish wetland influenced both by a seasonal high groundwater table and the fluctuating tide. The Salt Marsh boundaries extend along an abrupt toe-of-slope, and topography within the Salt Marsh is generally flat. The Salt Marsh is dominated by common reed (Phragmites australis) with fringing highbush blueberry, multiflora rose, and tartarian honeysuckle along the Salt Marsh boundaries. Dense entanglements of grape vine are common along the Salt Marsh boundaries. Bank Bank is defined at 310 CMR 10.54(2)(a) as the portion of land surface which normally abuts and confines a water body. The upper boundary of a bank is the first observable break in the slope or the mean annual flood level, whichever is lower. The lower boundary of a bank is the mean annual low flow level. Bank is associated with Long Pond, located within the northcentral portion of the site. The B-series Bank flags demarcate the Bank boundary which extends within 50 feet of the right-of-ways. The Bank is generally Page 6 of 7 located at the rear of residential lawns and is coincident with a break in slope, bank undercuts, changes in vegetation, and/or water staining. The portion of Bank delineated by the B-series Bank flags contains a paved boat launch that extends north from Piney Point Drive. Bank/Mean Annual High Water (MAHW) Mean Annual High Water (MAHW) is defined at 310 CMR 10.58(2)(a)(2) as the line that is apparent from visible markings or changes in the character of soils or vegetation due to the prolonged presence of water and that distinguishes between predominantly aquatic and predominantly terrestrial land. Field indicators of bankfull conditions shall be used to determine the mean annual high-water line. Bankfull field indicators include but are not limited to: changes in slope, changes in vegetation, stain lines, top of point bars, changes in bank materials, or bank undercuts Bank and the MAHW line are associated with three perennial streams; two are unnamed and one is the Centerville River. One unnamed stream is located within the C, E, and F-series BVW and at its closest point is at least 100 feet away from a right-of-way (Briarcliff Lane). Bank/MAHW associated with the stream is entirely contained within the BVW system and was not delineated in the field as it is located beyond 50 feet from the right-of-way. The second perennial stream is located within the central portion of the site and is partially demarcated by Bank flags A1 – A12 where it is present within 50 feet of the Pine Street right-of-way. This stream flows in a southerly direction from Long Pond within a linear, manmade channel with nearly vertical bank heights, continues through a culvert beneath Pine Street, and ultimately discharges into the Centerville River. The entire stretch of this unnamed intermittent stream is located within 200 feet of Holly Lane, Blantyre Avenue, Pine Street, Stanley Way, and the western portion of Riverview Lane. A segment of the Centerville River is the third perennial stream, located in proximity to the eastern portion of Riverview Lane. This portion of the Centerville River is entirely located within the Salt Marsh and is greater than 50 feet from the right-of-way. Land Under Water Bodies and Waterways (LUW) LUW is defined at 310 CMR 10.56(2) as 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 associated with the aforementioned Long Pond and three perennial streams. LUW is situated downgradient of the delineated and approximate Bank and Bank/MAHW lines associated with Long Pond and the perennial streams, respectively. Riverfront Area Riverfront Area is defined at 310 CMR 10.58(2)(a)(3) as the area of land between a river's mean annual high-water line measured horizontally outward from the river and a parallel line located 200 feet away. The 200-foot Riverfront Area extends from the approximated Bank/MAHW lines associated with the perennial streams. As previously noted, the Bank/MAHW lines were not delineated in the field as they Page 7 of 7 were generally beyond the 50-foot survey limits, with the exception of Bank flags Bank A1 – Bank A12. The Riverfront Area contains portions of the upgradient BVWs, residential dwellings and associated appurtenances, and the Briarcliff Lane, Pine Street, Blantyre Avenue, Holly Lane, Stanley Way, and Riverview Lane right-of-ways. Land Subject to Coastal Storm Flowage (LSCSF) LSCSF is defined as land subject to any inundation caused by coastal storms up to and including that caused by the 100-year storm, surge of record or storm of record, whichever is greater. [the Act Regulations, 310 CMR 10.04]. As previously noted, small portions of Pheasant Way and Katherine Road located within the southern portion of the site are mapped within a Zone AE (el. 13). Any portion of the Zone AE that extends beyond the aforementioned Wetland Resource Areas is located within LSCSF. Summary LEC identified and delineated the boundary of two contiguous BVWs, Salt Marsh, Bank to Long Pond, Bank/MAHW to a perennial stream, Land Under Water Bodies and Waterways, and the 200-foot Riverfront Area within a portion of the project area associated with the Long Pond Sewer Extension Project located in Barnstable (Centerville), Massachusetts. LSCSFF may also be present within southern portions of the project area. As noted throughout the report, LEC delineated Wetland Resource Area boundaries within 50- feet of the public right-of-ways and approximated Wetland Resource Area boundaries beyond 50 feet of the public right-of-ways. The aforementioned Wetland Resource Areas are protected under the Massachusetts Wetlands Protection Act (“WPA,” M.G.L. c. 131, s. 40) and its implementing Regulations (310 CMR 10.00), the Town of Barnstable Wetlands Protection Bylaw (Chapter 237) and its implementing Regulations, and the Federal Clean Water Act (“CWA”; 33 U.S.C. 1344, s. 404) and its Regulations (33 CFR and 40 CFR). Any new proposed alteration within the Wetland Resource Areas or the associated 100-foot Buffer Zone may require filing the necessary permit applications with the Barnstable Conservation Commission and the Massachusetts Department of Environmental Protection (MassDEP). Furthermore, proposed alteration within any of the Wetland Resource Areas may also require filing the necessary permit applications with the Department of the Army Corps of Engineers.
