This investigation area is located on and undeveloped parcel surrounded by residential properties. Please see Figure 1 (Wetlands Field Map) and Figure 2 (USGS Topographic Map) of this report for the investigation area. Wetland resource areas including an isolated vegetated wetland, were identified and flagged in the field using pink flagging by a Weston & Sampson employee who is trained in the wetland delineation process using the Massachusetts Department of Environmental Protection (MassDEP) and the US Army Corps of Engineers methodology. Further description of this wetland resource area is presented in the following sections. 2-1 Wetland Delineation Report Oldham Road, Barnstable MA westonandsampson.com 2.0 DELINEATION OF WETLAND RESOURCES 2.1 Site Observations The Weston & Sampson wetland scientist, trained in the ACOE Wetland Delineation Manual and Massachusetts Department of Environmental Protection (MassDEP) Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetland Protection Act guidance document, observed the following protected wetland resources at the site: - Isolated Wetland (IW) Field data were recorded on US Army Corps of Engineers (ACOE) Wetland Determination Data Forms. See Appendix A for completed data forms and Appendix B for site photographs. 2.2 Wetland Delineation Methodology A wetland delineation assessment was conducted in accordance with the Massachusetts Wetland Protection Act Regulations (310 CMR 10.55(2)(c)), Massachusetts Department of Environmental Protection (MassDEP) Massachusetts Handbook for Delineation of Bordering Vegetated Wetlands (Second Edition, September 2022), and ACOE Wetland Manual (Technical Report Y-87-1) and the Town of Barnstable Chapter 237 Wetland Protection Regulations. The bordering vegetated wetlands (BVW) delineation methodology included the characterization of vegetation, hydrologic conditions, and soil in both wetland and upland areas to identify the transitional area, which was used as the wetland limit. Pink flags with distinct flag numbers were left in the field to show wetland resource area limits. Vegetation, hydrology and soils were assessed in both wetland and upland areas to accurately place the wetland limits at each site. The percentage of vegetative species was estimated by creating sample plots. Sample plot radius for trees, saplings, shrubs, groundcover and woody vine strata was 30’, 15’, 15’, 5’ and 30’, respectively. After creating the sample plot areas, the percent basal area coverage of each species within the monitoring plot was recorded. Using these field observations, the percent dominance of each species within its stratum was calculated. The 50/20 Rule was then used to determine dominance. Dominant species were considered the most abundant plant species (when ranked in descending order of abundance and cumulatively totaled) that immediately exceeds 50% of 2-2 Wetland Delineation Report Oldham Road, Barnstable MA westonandsampson.com the total dominance measure (basal area) for the stratum, plus any additional species comprising 20% or more of the total dominance measure for the stratum. Once the dominant species were determined, they were treated equally to determine the presence of hydrophytic vegetation. If the number of dominant species with a Wetland Indicator Status of FAC (excluding FAC-), FACW or OBL is greater than, or equal to, the number of remaining dominant species, the area was considered a jurisdictional wetland resource area based on vegetation. A soil sample from each wetland sample plot were also taken. Each soil sample goes to a depth of at least 12-24 inches. The soil was characterized to determine if the soil sample was considered a hydric (wetland) soil. Soil samples, including mottles, were characterized based on color using Munsell Soil- Color charts as a color reference. The general area was then assessed for hydrologic conditions, including, but not limited to, site inundation, depth to free water, depth of soil saturation, water marks, drift lines, sediment deposits, water stained leaves. 2.3 Isolated Vegetated Wetland (IW) A single Isolated Vegetated Wetland (IW) series was delineated at the site. The limit of the IW resource area was determined by locating the transitional area between wetland and upland vegetation, soils and hydrologic conditions. Vegetation, hydrology and soils were assessed in the same manner as described above for identifying BVW. Wetland flags left in the field included: - WET-A1 through WET-A9 (IW “A” Series) Dominant vegetation within the IW included Acer rubrum, Ilex verticillata, Vaccinium corymbosum, Juncus effusus, and Sparganium americanum species that commonly thrive in hydric conditions. The soils were composed of a thick organic layer above fine sandy loam with redoximorphic features. Other indicators of hydrology included surface water, high water table, saturation, water stained leaves, and geomorphic position. 2-3 Wetland Delineation Report Oldham Road, Barnstable MA westonandsampson.com The adjacent upland vegetation was dominated by Pinus strobus, Pinus resinosa, and Kalmia angustifolia. Soils were composed of fine sandy loam. No indicators of wetland hydrology were observed. The Massachusetts Wetland Protection Act does not typically protect isolated vegetated wetlands, unless they meet the criteria for Isolated Land Subject to Flooding (ILSF). Pursuant to 310 CMR 10.57(2)(b), ILSF is an isolated depression or closed basin without an inlet or an outlet which at least once a year confines standing water to a volume of at least ¼ acre -feet and to an average depth of at least six inches. IW A does not appear to be large enough to hold the volume of water required to be jurisdictional as ILSF. However, it is recommended that project engineers perform the necessary calculations to confirm that the IW would not hold the requisite volume of water to be considered ILSF. Certain individual communities have chosen to extend protections to these isolated wetlands or vernal pools within their local bylaws including the Town of Barnstable. Under the Chapter 237 Wetland Protection Regulations the Town of Barnstable has defined jurisdiction as “no person shall remove, fill, dredge, or alter in or within 100 feet of the following resource areas: surface water body, vegetated wetland or unvegetated wetland; any land under said waters; and any land subject to flooding or inundation by groundwater, surface water, tidal action or coastal storm flowage”. 2.4 Other Protected Areas Weston & Sampson created environmental resources maps (see Figure 4) of the site to determine the presence of other protected areas. The data source of these map layers was the Massachusetts Geographic Information System (MassGIS). These areas included: - NHESP Priority Habitats of Rare Species - NHESP Estimated Habitats of Rare Wildlife - NHESP Certified and Potential Vernal Pools - Areas of Critical Environmental Concern (ACEC) - Outstanding Resource Waters (ORW) - Coldwater Fisheries - Shellfish Suitability Area - Article 97 Land 2-4 Wetland Delineation Report Oldham Road, Barnstable MA westonandsampson.com Wetland resources identified in the field were also added to these maps. Based on the MassGIS information the isolated wetland is shown as an NHESP Potential Vernal Pool. 3-1 Wetland Delineation Report Oldham Road, Barnstable MA westonandsampson.com 3.0 SUMMARY On April 11, 2023, the presence of wetland resources was investigated near Oldham Road in Barnstable, MA. A single isolated vegetated was identified and flagged at the site. Additional environmental mapping was conducted using MassGIS data layers and FEMA FIRM mapping. This additional mapping indicates that the isolated wetland is a NHESP Potential Vernal Pool.
