Executive Summary This design report document outlines the approach taken to develop the restoration designs for the headwaters of the Bass River. The sections below describe the data collected, methods used, and data analyzed; the document also summarizes the design elements shown on the design drawings. We have provided a recommended construction sequencing. This document is not meant to be used by the construction contractor to construct the work. This document may be used, in whole or in part, to facilitate regulatory review of the restoration project. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 1 2. Introduction The Bass River estuarine system is the longest river on Cape Cod, extending approximately seven miles. Forming the town line between Dennis and Yarmouth, the river is an important waterway for boating, fishing, and swimming. Anthropogenic impacts have degraded the river’s water quality and ecological functioning. Although cranberry bogs in the headwaters were retired over 40 years ago, the headwaters stream remains hydrologically and hydraulicly altered. The Friends of the Bass River and the Town of Yarmouth are looking to return the bogs to ecologically functioning wetlands and restore passage for aquatic organisms. Inter-Fluve began working on feasibility and design concepts in September 2020 and preliminary designs in 2022. Work included: • Field data collection programs o Topography and bathymetry surveys: October 13-15, 2020; November 4-5, 2020; January 28-29, 2021 o Sediment sampling: Oct. 13, 2020 • Feasibility analyses o Sediment analysis o Conceptual development • Preliminary designs o Ecological restoration designs for the retired cranberry bogs (Inter-Fluve) – design drawings, basis of design report (this document), engineer’s opinion of probable construction cost o Weir Road crossing design (Tighe & Bond) – design drawings, basis of design report, engineer’s opinion of probable construction cost o Pedestrian crossings (Stimson Associates) – design drawings This report provides a summary of Inter-Fluve’s work to date and presents the information that forms the basis of the preliminary restoration designs (i.e., 60% design completion level). Our scope is focused on the restoration of stream and wetland function and habitat; the road crossing at Weir Road is being designed by Tighe & Bond and tidal analyses were completed by Woods Hole Group to facilitate the designs for the North Dennis Road crossing downstream of the limits of work for this restoration effort. 2.1 PROJECT GOALS Specific goals of the Bass River Headwaters Restoration Project (the Project) are to: • Replace an undersized culvert (Weir Road); • Improve water quality through nutrient attenuation that occurs in healthy wetland habitats; • Improve fish passage; • Enhance habitat for aquatic and wetland organisms; • Restore salt marsh habitat, improve coastal resiliency to flooding, and allow for future marsh migration; • Improve ecological diversity and health of the bog surface; and • Improve passive recreational opportunities. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 2 2.2 PROJECT PARTNERS The Project benefits from the support of the following Project Partners: • Friends of the Bass River (FOBR); • Town of Yarmouth – property owner and permit applicant; • US EPA Southeast New England Program (SNEP) grant – awarded a grant to FOBR to fund the current design and planning tasks; • Woods Hole Group – contracted to the FOBR to conduct tidal analyses; and • Tighe & Bond – contracted to the FOBR to complete culvert and bridge designs at the North Dennis Road and Weir Road crossings; • Stimson Associates – contract to the Town to complete designs for the pedestrian crossings. 3. Project Area In this report, we evaluate an area of retired cranberry bogs and an impaired culvert located in the Upper Bass River watershed in Yarmouth, Massachusetts (Figure 1). In the headwaters of the Bass River where the study area is located, the stream is historically known as Hamblin’s Brook. Hamblin’s Brook emerges from groundwater springs north of Route 6 in a series of cranberry bogs upstream of Union Street. Hamblin’s Brook flows through flow-control structures at Union Street and then into Miss Thatcher’s Pond, an impoundment created by a dam and earthen berms as a water supply for the cranberry bogs. The brook leaves Miss Thatcher’s Pond through a fish ladder and then flows under Weir Road and through more retired cranberry bogs before it drains into Mill Pond. 3.1 PROJECT SITE The Project Site is the area available for active construction and staging. The site is owned by the Town of Yarmouth and is located south of Route 6a, north of Route 6, east of Union Street and west of Mill Pond (Figure 1). The area includes approximately 57 acres of retired cranberry bogs and the headwaters of the Bass River historically known as Hamblin’s Brook. Please refer to the accompanying drawings for the cell numbers assigned to each bog and referenced in this report. Miss Thatcher’s Pond Miss Thatcher’s Pond is the upstream extent of the Project Site, with a surface area of approximately 0.8 acre (Figure 2). According to historical records, farmers excavated the wetlands to create a pond they could use as an irrigation source for their cranberry bogs. The pond has a maximum depth of 4 feet and the average depth is approximately 2.5 feet. Miss Thatcher’s Pond is divided into two main components. The southern portion is larger and deeper and was the primary water source for farming. The northern portion was a cranberry bog before being converted to a pond between the 1930s and 1970s. Historical topographic maps from the U.S. Geological Survey show the pond having two outlets: one flows north very close to the location where Hamblin’s Brook enters Miss Thatcher’s Pond and one flows into the project area to the east (Figure 3). The outlet to the north has been abandoned, and we were unable to locate the ditch during the site assessment. Portions of the ditch have been filled in, and houses have been built MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 3 on top of the fill along Seminole Drive and Starbuck Lane. North of Starbuck Lane, we were able to identify the ditch, but the culvert under the road was not present or likely filled in through road reconstruction and housing development. The fish ladder at the eastern outlet of the northern portion now controls water levels of the pond (Figure 4). The fish ladder consists of a series of boards placed between two concrete slabs that extend 20 feet long. Each step is 3 feet wide. From the fish ladder, the river flows into the first area of cranberry bogs. According to the Massachusetts Department of Environmental Protection (DEP) Drinking Water Program, Miss Thatcher’s Pond is within a DEP Approved Wellhead Protection Area (Zone II). Miss Thatcher’s Pond is the eastern-most boundary of the protection area, suggesting that Miss Thatcher’s Pond is at a hydrogeologic boundary. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 4 Figure 1. Project area location map MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 5 Many areas of Miss Thatcher’s Pond have filled in with organic material and aquatic vegetation, resulting in low levels of dissolved oxygen and elevated water temperatures. Water warmed in Miss Thatcher’s Pond flows downstream, degrading water quality through the rest of the Bass River watershed. While conducting our survey and site assessment, we observed ducks, geese, and swans in Miss Thatcher’s Pond. One resident spoke about large snapping turtles that he observed in the pond. Though no records are available, we assume that warm-water fish species currently live within the pond. Along the northern and eastern edges of Miss Thatcher’s Pond, an earthen berm was created to maintain water levels and separate the pond from Cells 2 and 4. This earthen berm remains intact, though portions of the berm are showing signs of deterioration with erosion around disused flow control structures. Two flow control structures had historically carried water from the pond to the cranberry bogs to the north, but these culverts have filled in and no longer support flow. A former pump house was located on the earthen berm with only a portion of its concrete walls now remaining. Figure 2. Miss Thatcher's Pond MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 6 Figure 3. U.S. Geological Survey topo map of Miss Thatcher's Pond, 1940s. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 7 Figure 4. Miss Thatcher’s Pond outlet and fish ladder Cranberry Bogs Between Miss Thatcher’s Pond and Weir Road Cells 1-4 (refer to the drawings) are defined by a levee that divides Cells 1 & 3 from Cells 2 & 4. The Project Site includes the levee, an adjacent ditch, and the bogs in Cells 1 & 3. The main channel through the bogs runs along the left toe of the levee (looking downstream) in Cell 3 (Figure 5). The main channel has a bottom width that ranges from 7 to 11 feet and a bank height of approximately 1.5 to 3 feet. At certain spots throughout Cell 3, the channel becomes less defined as water spreads throughout the relic side ditches on river left. The water level through Cell 3 is dictated by flow control structures downstream of Weir Road that currently elevate the water. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 8 During the site assessment, we examined portions of the main channel with active flow for an indication of appropriate design channel sizing. Approximately 75 feet downstream of the fish ladder at Miss Thatcher’s Pond, trees have grown close to the channel and roots obscure portions of a nearby ditch leaving an active flow area of approximately 4 feet wide at the top of bank and 1 to 1.5 feet deep (Figure 6). Here, the water moves more swiftly than elsewhere, is close to the top of bank, and has created some scour around the roots. Further downstream where the water spreads into the adjacent vegetation, the active flow appears to be limited to an approximately 4-foot-wide channel between hummocks (Figure 6). Much of the cranberry bog landscape is now a mix of hummocks of vegetation and deep pockets of water. The vegetation in Cells 1 & 3 is a mix of sphagnum moss, shrubs, and red maple saplings over 20 feet in height. In Cells 2 & 4, higher water levels limit woody growth and vegetation is mainly herbaceous, primarily grasses, rushes, sedges, and sphagnum moss. Figure 5. Looking downstream along the top of a levee separating Cells 1 & 3 from Cells 2 & 4. The main channel within the Project Site runs along the left toe of the levee in Cell 3. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 9 Figure 6. Approximately 75 feet downstream of the fish ladder at Miss Thatcher’s Pond, vegetation and roots have constrained the channel to be approximately 4 feet wide at the top of bank (left). Further downstream, the effective flow through the hummocky vegetation is approximately 4 feet wide at the top of bank (right). Weir Road Culvert The Weir Road culvert, a stone masonry box culvert, has partially collapsed. On the downstream side of the road, the existing opening is 3.2 feet wide and 2.5 feet tall. On the upstream side of the road, the existing opening is 1.8 feet wide and 2 feet tall. The weir road crest elevation is 10.7 feet. In addition to its poor physical condition, the culvert restricts flood flows and elevates water levels upstream. Weir Road is classed as an Urban Local Road/ Rural Minor Collector. It mostly serves the residential areas that surround it. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 10 Figure 7. Culvert at Weir Road Cranberry Bogs Between Weir Road and Cheyenne Lane The Project Site downstream of Weir Road consists of another area of retired cranberry bog (Cell 5). Approximately 75 feet downstream of Weir Road, the channel splits in two with flow control structures regulating water elevations in each channel. A straightened ditch conveys a portion of the flows to the northeast, while a more natural-looking sinuous channel conveys water to the northwest. These two channels generally flow north/northeast and under the earthen berm and walkway between Cheyenne Lane and Knollwood Drive. Ditches through Cell 5 currently hold water and historically would have conveyed water from the ditch to the bog platform as needed for farming. The more natural-looking channel ranges in width from 12 to 18 feet and becomes undefined in the middle of this former bog. The levee adjacent to the ditch has been converted into a walking path for public use. The vegetation within Cell 5 has grown substantially since the bogs were abandoned. In the middle of the bog along the main channel, vegetation is primarily shrubs and grass hummocks where water levels are elevated because of the undersized and clogged culvert downstream (see below). Elsewhere, mature red maple and pitch pine trees have grown to more 30 feet in height. The lateral MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 11 and perimeter farm ditches remain visible, though many have partially filled in with sphagnum moss. Small patches of the invasive plant Phragmites were observed in the northeastern portion of this bog. At the downstream end of Cell 5, the channel flows through an undersized, 18-inch corrugated metal culvert beneath the earthen berm and walkway between Cheyenne Lane and Knollwood Drive (Figure 8). The culvert is partially filled and restricts flows, increasing the water elevations upstream of the crossing. Figure 8. Looking upstream at the 18-inch corrugated metal pipe under the earthen berm and walkway between Cheyenne Lane and Knollwood Drive MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 12 Cranberry Bogs Between Cheyenne Lane and Mill Pond Downstream of the earthen berm between Cheyenne Lane and Knollwood Drive is another former cranberry bog (Cell 6) with a straightened ditch flowing along the southern edge and a more natural stream channel flowing east along the northern and middle portions of the bog. An earthen berm separates the ditch from the bog and is currently used as a walking path. In the southwest corner of the bog, we found remnants of the site’s history as a cranberry farm: Abandoned farm equipment sits partially buried and obscured by vegetation, and mounds of disposed earth from digging out ditches dot the surface (Figure 9). The western portion of the bog has mature trees and understory vegetation, and the eastern portion is made up primarily of woody shrubs and other marshland vegetation. Phragmites has spread through the eastern portion of the marsh. At the eastern end of the bog, an earthen berm separates the wetland from Mill Pond. The channel exits through a gap in this berm with abandoned farm equipment and flow control structures nearby. This portion of the wetland and Mill Pond experience tidal fluctuations. To the south, is another abandoned cranberry bog with wetland vegetation growing throughout (Cell 7). Ditches have filled in with sphagnum moss and other vegetation. In the wetter areas, shrubs and herbaceous plants thrive while maple and pitch pine trees grow in the drier areas. Groundwater from the nearby hillslopes flows through the ditches of this abandoned bog and into Mill Pond under the earthen berm and path.

Data Collection and Review 4.1 DESKTOP DATA REVIEW We conducted a desktop review of existing data to understand the broader context of the site and restoration project and to identify design constraints and opportunities. Land Use/ Land Cover, Geology, and Soils The headwaters of the Bass River watershed comprise primarily forested and single-family residential areas. The remaining area is forested and non-forested wetlands with some commercial land to the south of Route 6. Residential development throughout the watershed has led to increased nitrogen and nutrient loads to the groundwater and subsequent surface water in Mill Pond and further downstream. No significant sources of industrial or commercial impacts to the soils or water are known except for the chemical use on the former cranberry bogs. We describe the results of our bog soil sampling and testing in Section 5. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 14 The headwaters of the Bass River are near the crest of Cape Cod with the northern part of the Cape draining to Cape Cod Bay, and the south draining to Nantucket Sound. The soils in the headwaters area are a glacially-derived mix of sand and gravel with a high infiltration rate (Group A) and a moderate infiltration rate with a high-water table (Group B/D).1 The soils within the Project Site are made up of Freetown coarse sand spread by farmers over Freetown muck, the organic peat and wetland soils that historically supported peatlands prior to the construction of dams and cranberry farms. FEMA Studies and Mapping The entire study area is within the Coastal AE Flood Zone with a 1% annual chance of flooding due to coastal storm surge. The base flood elevation calculated for this 1% annual chance of inundation is 13 feet (NAVD88) at the mouth of the Bass River at Nantucket Sound and 9 feet in Follins Pond, Mill Pond, and the study area. The effective date of the flood insurance rate map is July 16, 20142. Wetlands and Ecology The wetlands within the study area that were previously active cranberry bogs are now classified as Shrub Swamp and Deciduous Wooded Swamp by MassDEP and Freshwater/Forested Shrub Wetland and Freshwater Emergent Wetland by the National Wetlands Inventory3. The proposed work area is not within estimated or priority habitats of rare species and wildlife according to the Natural History and Endangered Species Program (NHESP) 14th Edition Heritage Atlas. The proposed work area is also not within an Area of Critical Environmental Concern or Outstanding Resource Waters. One of the goals of the project is to improve fish passage. Mill Pond and the headwaters of the Bass River were historically known to have large herring runs. By removing the flow control structures and undersized culverts within the study area, fish passage will be restored to headwater aquatic habitat for herring, American eel, and other species. Utilities Overhead electric lines were observed along Weir Road during the survey. The Town of Yarmouth confirmed that a water line is under Weir Road and another water line is under the earthen berm between Cells 5 and 6. Infrastructure Within the Project Site, infrastructure features include stream crossings and abandoned flow control structures in between the former bogs. In addition, the abandoned concrete foundation of a pump house remains along the eastern edge of Miss Thatcher’s Pond and a concrete fish ladder is present at the outlet of Miss Thatcher’s Pond. 1 NRCS, SSURGO/STATSGO dataset. 2 Federal Emergency Management Agency [FEMA], 2014. Flood Insurance Study, Barnstable County, Massachusetts. FIS No. 25001CV000A. Effective July 16, 2014 3 http://maps.massgis.state.ma.us/map_ol/oliver.php accessed April 30, 2021 MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 15 Two stream crossings within the Project Site restrict flow and fish passage: Weir Road and the berm/path crossing farther downstream between Cheyenne Lane and Knollwood Drive. Both will be addressed as a part of the project scope. Recreation The Project Site is currently used by the public for walking and wildlife viewing; however, many of the trails are overgrown and difficult to navigate. The trails are located along the earthen berms created during cranberry farming to separate the bog cells. One of the goals of the project is to enhance recreational opportunities by improving trails and installing other improvements. Historical/ Cultural Resources Prior to European colonization, the Pawkunnawkuts of the Wampanoag nation prospered along the Bass River. Decimated by the early colonizers through disease and fighting, the remaining Pawkunnawkuts sold their land to European farmers in the late 17th century. As villages were established, the river was used to support industry, fishing, and recreation. According to a local historian, there was a mill at the west end of Mill Pond in the 1750s.4 In the 1880s, there was a major herring run that went through the channel at Weir Road. Fish populations in the Upper Bass River dropped after the construction of the railroad bridge downstream of the present Route 6 in 1857. Another major ecological disruption starting in the 1800s was cranberry farming, which led to the sanding, damming, and ditching of the headwaters of the Bass River. Like many cranberry bogs throughout the Cape, the bogs at the Bass River headwaters are now retired. No state-listed historical sites are known to exist within the study area5. The Massachusetts Historical Commission had no comment, and did not request additional studies, after we submitted a project notification form during the MEPA review process. Climate Change The project area is impacted by climate change through increased frequency of higher magnitude storm events, sea level rise, increased air temperatures, and periods of drought. Section 6 describes our hydrologic analyses, including consideration of climate change and sea level rise. Our restoration design approach at the site will aim to be resilient to climate change and sea level rise. The stream will have channel banks that can adjust in dimensions over time as sea levels rise. The removal of berms and flow barriers will provide more area for tidal flows, enhancing resiliency to changing sea levels. 4 https://us15.campaign-archive.com/?u=7095ce76f601af31d8c3bbd51&id=6c5356a123 5 http://maps.massgis.state.ma.us/map_ol/oliver.php accessed April 30, 2021 MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 16 4.2 FIELD DATA COLLECTION Topographic Survey We collected topographic and bathymetric survey data on October 13, 14, and 15, 2020, November 5, 2020, and January 28-29, 2021 using Real Time Kinematic and Total Station surveying equipment. We captured the hydraulic control features and critical channel elevations starting at Miss Thatcher’s Pond and ending at Mill Pond. Geomorphic Assessment Geomorphologists assessed the project site during the same period as the topographic survey, October 13-15, 2020. We reviewed the channel and wetland conditions, the system of ditching, flow control structures, and the vegetative growth within the aquatic and terrestrial ecosystems. Our observations are described in Section 3.1. Sand and Peat Characterization We evaluated the depth of sand and peat at select locations within the bogs and analyzed sediment samples collected from the sand and peat layers for a range of contaminants. A sampling plan and testing results are described in Section 5. 4.3 SITE CONSTRAINTS The existing data review and site assessments and surveys provided valuable opportunities to evaluate the constraints that might challenge ecological restoration efforts. The primary challenge that we observed will be staging and access. We did not observe any large open areas for staging, so the staging areas will need to be developed through clearing of vegetation and leveling of the ground surface in select areas. Access is also complicated with the multiple work areas. No access for construction vehicles exists off Weir Road, so access roads will need to be developed along the existing earthen berms and footpaths on either side of the road. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 17 5. Sediment Analysis This restoration project will require the receipt of a valid Water Quality Certification (WQC) from the Massachusetts Department of Environmental Protection (MassDEP). MassDEP requires contamination analytical results for the areas of ground disturbance within wetland areas. While all excavated soils will be reused on site and not brought to a landfill or other disposal location, contamination concentrations of the excavated soils are still required by MassDEP. This section describes the sediment sampling and results completed to date. 5.1 DUE DILIGENCE REVIEW Per the requirements of 314CMR9.07(2) we completed a due diligence review. We reviewed the following databases for possible sources of contamination within the contributing watershed of the study area: Database Finding National Priorities List (Superfund)6 None CERCLIS/NFRAP7 None RCRA8 No large waste generators MassDEP9 No Activity and Use Limitations; no underground storage tanks Based on these findings, the sediment sampling plan must address the requirements of 314CMR9.07(2)(B)(6) with the analysis of samples for the following parameters: • Metals o Arsenic o Cadmium o Chromium o Copper o Lead o Mercury o Nickel o Zinc • Polycyclic Aromatic Hydrocarbons (PAHs) • Polychlorinated Biphenyls (PCBs) by NOAA Summation of Congeners • Extractable Petroleum Hydrocarbons (EPHs) • Volatile Organic Compounds (VOCs) 6 https://www.epa.gov/enviro/sems-search accessed April 30, 2021 7 https://www.epa.gov/enviro/sems-search accessed April 30, 2021 8 https://www.mass.gov/guides/hazardous-waste-generation-generators accessed April 30, 2021 9 http://maps.massgis.state.ma.us/map_ol/oliver.php accessed April 30, 2021 MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 18 • Total Organic Carbon • Percent Water • Toxicity Characteristic Leaching Procedure • Grain Size Distribution Because of the history of agricultural use within the watershed and project site, we also analyzed sediment samples for organochlorine pesticides. 5.2 SEDIMENT SAMPLING PLAN We collected six (6) sediment samples throughout the study area on October 13, 2020: • Downstream work area near Mill Pond – 1 sample of the sand layer and 1 sample of the peat layer; • Upstream of Cheyenne Lane within the southern portion of the bog – 1 sample of the sand layer and 1 sample of the peat layer; • Downstream of Weir Road – 1 sample within the active stream channel; and • Upstream of the earthen dam and concrete fish ladder at Miss Thatcher’s Pond – 1 sample within the impoundment. Samples were collected using a custom-made hand coring device. Sampling procedures followed Inter-Fluve’s internal guidelines based on Massachusetts, Wisconsin, and USEPA sampling recommendations10. Samples were submitted to Absolute Resource Associates, a Massachusetts certified laboratory, for analysis. 5.3 LABORATORY ANALYSIS The sediment samples analyzed generally had contamination concentrations under the human health and ecological thresholds, with the following exceptions: • BR2P – arsenic exceeded the MCP S1 human health threshold and the PEC ecological threshold; • BR2S – dieldrin and DDE exceeded the PEC ecological thresholds; and • BR4 – DDD exceeded the PEC ecological threshold. For a detailed table of all results, see Appendix A. 5.4 SEDIMENT MANAGEMENT APPROACH Multiple restoration projects involving retired cranberry bogs have been permitted by MassDEP and municipal conservation commissions. The sediment management plan for this project will follow those of the previously permitted and completed projects: All excavated soils will be reused on site to fill ditches and other areas previously excavated during cranberry cultivation. No soil or sediment is proposed to be disposed of, or reused, at offsite locations. 10 Inter-Fluve 2007 MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 19 6. Hydrologic Analysis The Bass River Headwaters Restoration Project includes restoring several cranberry bogs and replacing the Weir Road crossing. Both of these project elements are affected by normal daily streamflow and peak flood flows in Hamblin’s Brook. Because Cape Cod is underlain by highly pervious sand and gravel, infiltration rates are high, and groundwater is a primary driver of streamflow in this region. For this study, we evaluated the hydrologic characteristics of Hamblin’s Brook and the contributing watershed. The hydrologic evaluation included field data collection and desktop analyses. This section of the report describes the approach for selecting design flows for the simulated natural geomorphic channel for the restored Hamblin’s Brook and preliminary estimates for design flows for the replacement culvert at Weir Road. Tighe & Bond completed detailed hydrology and hydraulics analyses for the Weir Road crossing replacement under separate contract. In 2022, we also evaluated preliminary tidal datums because of the anticipated increased tidal influence within the Project Site following the replacement of the North Dennis Road culvert and as a result of sea level rise. Woods Hole Group completed more detailed studies and modeling to refine these tidal datums under separate contract. 6.1 USDA TR-55 ANALYSIS The Natural Resources Conservation Service (NRCS) Technical Release 55, Urban Hydrology of Small Watersheds (TR‐55) rainfall‐runoff analysis method is an industry standard method for estimating discharge-frequency curves. However, it assumes that peak flows in surface waters are driven by surface runoff, not by groundwater baseflow. We therefore adapted some of the procedures in TR-55 to better represent conditions and processes in the watershed. More detail is provided below. We used HydroCAD software to simulate runoff hydrographs for a suite of design events ranging from the 1‐ to 500‐year average return period events. Watershed Characteristics We delineated the contributing area for the watershed to Weir Road using the USGS dataset “Groundwater Contributing Areas for Cape Cod and the Plymouth Carver Regions of Massachusetts” in combination with LiDAR data and a series of ArcGIS tools. We used the 2005 MassGIS Landuse/Land Cover Dataset to determine the primary land uses within the watershed (Table 1). The watershed consists primarily of forest and residential land. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 20 Table 1.

The data used in the RCN analysis is based on data from the following sources: • NRCS Soil Survey Geographic Database (SSURGO) dataset available for download from MassGIS; • 2005 land use data available for download from MassGIS; • Watershed delineations by Inter‐Fluve, as described above; and • RCNs available in TR‐55. We assigned an RCN to each area with a unique hydrologic soil group and land use combination and then calculated the area‐weighted RCN for the watershed. Time of Concentration We calculated a time of concentration (TC) for each watershed in the study area using a novel method that considers the unique geology of Cape Cod. Most of the rainfall on Cape Cod quickly infiltrates to groundwater. For this application, we developed a TC flow path in a GIS environment using the USGS groundwater contributing areas, and assumed a travel velocity commensurate with the hydraulic conductivity of a gravel/clean sand aquifer11. For this application, we assumed a subsurface flow rate of 3.7 feet per minute. 11 Allen Freeze and John A Cherry. Groundwater. Prentice‐Hall, Inc.

This is attributable to the low-lying topography and regional geologic patterns that include lithology of coarse-grained stratified drift, which complicate delineation of contributing areas and groundwater patterns and complicate attempts to model rainfall-runoff processes. 6.2 HYDRAULIC DESIGN CRITERIA The peak flood flows from the rainfall-runoff analysis will be used as inputs into the hydraulic modeling to inform the design of various project components. Prior to carrying out the modeling, we developed the following hydraulic design criteria to help focus our efforts and adhere to state guidance where appropriate. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 23 Weir Road Culvert Because Weir Road is classified as an Urban Local Road/ Rural Minor Collector, the following design events will be evaluated according to the Massachusetts Department of Transportation (MassDOT) Requirements for New and Full Bridge Replacement Projects Guidelines12: 10-year event for flood frequency, 25-year event for design scour frequency, and 50-year event to check scour frequency. The guidance also states that the bridge must be scour stable after the Design Scour Event but does not necessarily need to be available for use. See the Tighe & Bond design report for more details on the Weir Road designs. Channel Form The channel cross sectional geometry will function in an ecologically and geomorphically appropriate manner for streams on Cape Cod. The channel form and dimensions will be adaptable to increased tidal influence through improved tidal flows downstream and future sea level rise. Rock Sizing The designed channel substrate will be stable during the stability design event (i.e., the 25-, 50-, or 100-year event, whichever results in the highest peak stresses on the channel bed). 7. Hydraulic Analysis We developed a hydraulic model of the Bass River that extends from Mill Pond upstream to Miss Thatcher’s Pond. The hydraulic model is designed to provide a basis of comparison between the existing condition of the headwaters of the Bass River (Hamblin’s Brook) and the proposed design condition. The hydraulic model of Bass River is designed to: • Simulate hydraulic conditions at the Weir Road culvert, • Simulate project impacts on flood profiles, velocities, and bed shear stresses during peak flood flows. 7.1 METHODS We built a one-dimensional, steady flow hydraulic model using the U.S. Army Corps of Engineers Hydraulic Engineering Center River Analysis System (HEC-RAS) software version 5.0.6. We developed the existing conditions model geometry using the field survey data collected. We supplemented these data with high-resolution LiDAR data from a 2011 USGS dataset. The flood events analyzed in the model include the 1-, 2-, 5-, 10-, 25-, 50-, and 100-year flood estimates, as recommended by MassDOT. 12 https://www.mass.gov/doc/municipal-small-bridge-program-design-requirements-for-new-and-full-bridge- replacement-projects/download MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 24 7.2 EXISTING/BASELINE CONDITION The existing condition model provides a baseline for comparison with the proposed design. It represents the condition of the Bass River at the time of our surveys in 2020 and 2021. Model Geometry We developed a georeferenced model geometry in a GIS environment using RAS Mapper tools. The composite digital elevation model of the channel bathymetry and overland topography extends from approximately 3,500 feet downstream of the Bass River’s entrance into Mill Pond (west end of Mill Pond) upstream to approximately 1,000 feet upstream of Weir Road. Although the Project Site begins where the Bass River flows into Mill Pond, we continued the reach downstream into Mill Pond to capture the upstream boundary of North Dennis Road hydraulic model developed by Tighe and Bond. The composite digital elevation model includes high-resolution data from a site- specific bathymetric and topographic survey, supplemented with high-resolution LiDAR data (USGS, 2011). Figure 10. Map showing HEC-RAS cross section locations with inset of area around Weir Road. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 25 Boundary Conditions The downstream boundary conditions for the existing model are based on results from Tighe and Bond’s existing condition hydraulic model.13 Table 6Table 8 shows the MHHW and MLLW water surface elevations from river station 29+03 in Tighe and Bond’s existing model, which are used in our existing condition model as the downstream boundary conditions.

Overbank 0.070 Medium to dense brush, in winter Forest/shrub type overbank. Expansion and Contraction We assumed expansion and contraction coefficients of 0.1 and 0.3, respectively. These values are typical default values recommended in the HEC-RAS Hydraulic Reference Manual. At cross sections immediately upstream and downstream of crossings and flow control structures, we assumed expansion and contraction coefficients of 0.3 and 0.5, respectively. This is consistent with standard engineering practice. 13 Tighe and Bond, North Dennis Road Culvert Improvements Hydrologic and Hydraulic Analysis, Technical Memo, Aoril 2021. 14 United States Army Corps of Engineers (USACE) Hydrologic Engineering Center, February 2016.

MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 26 Ineffective Flows We applied ineffective flow areas at each culvert represented in the model in accordance with standard practice. We also applied ineffective flow areas to low points in overbank areas that do not convey water. 7.3 PROPOSED CONDITION We developed a proposed condition hydraulic model to represent the design condition shown on the 60% Engineering Design Drawings that accompany this report. Refer to Section 8 for a full description of the scope of work of the proposed project. Boundary Conditions According to Tighe and Bond’s H&H analysis report, they recommend the installation of a 60-foot span bridge, Alternative 3, to replace the current North Dennis Road culvert and maximize tidal exchange. Table 8 shows the MHHW and MLLW water surface elevations for river station 29+03 from Tighe and Bond Alternative 3 results used in our proposed condition model as the downstream boundary conditions.

We assumed a box culvert with a span of approximately 1.2 times the design bankfull width of the upstream channel and a minimum of two feet of vertical embedment. We then selected a standard culvert size with these dimensions plus the capacity to pass the 10-year flood peak with at least two feet of freeboard. The selected size is 16 feet wide by 6 feet high. For the proposed culvert, we assigned Manning’s “n” values of 0.013 for the concrete top of the structure and 0.045 for the bottom to represent the use of naturalized stream substrate. See the Tighe & Bond design report and design drawings for more details on the designs. 7.4 RESULTS AND DISCUSSION Proposed conditions model results including pre- and post-project water surface profiles, velocities, and shear stresses are presented below. The model results (Appendix C) indicate that the water- surface profiles will decrease, velocities will generally increase, and bed shear stresses will generally increase as a result of project activities. The reduction in water surface profiles results from the removal of undersized culverts and crossing improvements at North Dennis Road and Weir Road. Figure 11 illustrates the project impact on flood profiles for the 10-, 50-, 100-, and 500-year events. Model results support the conclusion that the project will not have an adverse impact on flood profiles along Bass River. 15 https://www.mass.gov/doc/massachusetts-stream-crossing-handbook/download MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 1 Figure 11.

The highest velocities occur at the steepest, upstream- most section of the project area. Despite these increases, the maximum velocities and shear stresses are still relatively low and will support stable bed and bank conditions along the project reach. Average channel velocities are predicted to remain below 2.8 feet per second, which is below the velocity at which channels with coarse sand are expected to scour Weir Road Culvert MassDOT classifies Weir Road as a Rural Minor Collector. The hydraulic, scour, and scour design events are the 10-, 25-, and 50-year events, respectively. See the Tighe & Bond design memo for details on the results of the modeling and implications on design. 8. Project Design The project scope of work includes removing and/or replacing barriers to flow and aquatic organism passage throughout the former bogs within the Project Site. Other elements of work are realigning the stream to increase sinuosity and create habitat variability; filling existing ditches and creating microtopography to help restore historical hydrologic and vegetative conditions; creating a new pond feature; and improving pedestrian access. 8.1 SUGGEST CONSTRUCTION SEQUENCE In this section, we provide a recommended construction sequence of restoration activities. Once a contractor has been selected, they will submit a detailed work plan with their own recommendations for sequencing. This will be reviewed by Inter-Fluve, the Town, and the FOBR before approval to do any work. The channel and floodplain work upstream of Weir Road have to be done in conjunction with the replacement of Weir Road as access is obtained when the road is closed and the restoration in Cells 3 and 4 are only functional once the flow control structures at and downstream of Weir Road are removed. • Mobilization o Install traffic control measures o Install sediment and erosion control features o Install stabilized construction entrances o Create staging areas • Close Weir Road at the stream crossing o Establish water control o Complete clearing and grubbing o Complete culvert removal and excavation to subgrade o Install new crossing and streambed material o Complete roadway replacement o Remove water control o Open Weir Road • While Weir Road is closed and the culvert is being replaced: MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 2 o Establish access into Cell 3 o Improve access around Cell 2 • Cell 1 o Establish water control in Cell 1 o Remove dam and fish ladder o Excavate pond and channel o Complete bank treatment and large wood installation o Microtopography o Remove water control • Cell 2 o Fill ditches • Cell 3 o Establish water control o Complete grading and channel construction o Install large wood o Microtopography o Remove water control • Cell 5 o Establish water control o Complete channel construction o Install large wood o Remove water control o Invasive species treatment o Complete floodplain grading o Complete microtopography • Cell 7 o Establish construction access o Complete grading o Complete microtopography • Cell 6 o Establish water control o Remove earthen berm at downstream end o Complete channel construction at the upstream end o Complete floodplain grading o Complete microtopography o Remove earthen berm between Cells 6 and 7 o Construct boardwalk between Cells 6 and 7 o Construct footbridge across channel at earthen berm between Cells 5 and 6 o Remove water control • Complete planting • Remove traffic signs as appropriate • Remove sediment and erosion controls once site has stabilized 8.2 SITE ACCESS AND STAGING This project site is spread out with multiple road and pedestrian crossings, making site access and staging challenging. We have identified two primary access and staging areas described below. MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 3 • Along the pedestrian path between Cheyenne Lane and Knollwood Drive o Access will be from the north off Knollwood Drive. A stabilized construction entrance will be constructed to reduce the tracking of sand and mud out of the Project Site. o The staging area will be on the southeast side of this pedestrian path in an area previously modified by cranberry farmers with earthen mounds derived from dredging ditches. The mounds will be smoothed out and existing ditches filled to form the staging area. • Along Weir Road o We propose a staging area with stabilized construction entrance on the north side of Weir Road opposite the crossroad of Seminole Drive. Temporary access roads can be developed by the contractor into the site from this location. Access to Cells 1 through 4 will be in the vicinity of the Weir Road culvert during the culvert replacement when the road is closed and construction vehicles can travel between Cells 4 and 5 more easily. 8.3 DAM REMOVAL The dam and fishway at Miss Thatcher’s Pond will be removed. The concrete fishway will be completely removed, and the contractor will dispose of the concrete in an approved off-site location. The earthen berm portion of the dam will be partially removed. We propose leaving approximately one vertical foot of the earthen berm above the adjacent floodplain elevation to provide a drier and more stable walking path for continued pedestrian access. The earthen berm will be removed laterally to the edge of the valley to the north and to the adjacent earthen berm to the south with walking slopes no steeper than 5:1. 8.4 WEIR ROAD CULVERT REPLACEMENT The Weir Road culvert will be replaced with a larger opening to allow for greater hydraulic capacity for passing flood flows. The stream channel design in the vicinity of and through the culvert has been completed by Tighe & Bond. 8.5 CHANNEL FORM AND HABITAT Upstream of Weir Road, the current channel is straight with uniform widths and depths and channel bed and banks primarily made of sand. The proposed channel will be a meandering channel with sinuosity calculations based on channel size, watershed size, slope, and regional reference reaches. Stream Channel Morphology To design a new stream channel, it is an important exercise to locate relatively undisturbed streams or streams that have achieved an equilibrium with their watershed landuse and hydrology. When choosing an analog or reference stream, the analog must have similar watershed and morphological attributes to the proposed restored channel, including: MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 4 • Watershed size; • Surficial geology; • Bordering vegetation; • Soils; and • Land use. There are few sites that check all the boxes since most streams and wetlands in New England have been manipulated for farming, deforestation, development or other means. We analyzed aerial photographs and maps of streams around Cape Cod and the South Shore to find reference sites. We also looked to the designs of our past cranberry bog restoration projects. To develop planform geometry values for design, we examined belt width, meander length, and radius of curvature for reference stream segments and past project designs in the following watersheds: • Upper Herring River; • Herring Brook; • Eel River; and • West Beaver Dam Brook. We then correlated planform values with the watershed area and used ranges of each parameter to guide the form of the new channel upstream of Weir Road. We designed the stream to have a slightly irregular meander pattern based on the reference and past project sites. The planform values that guided our design are listed in Table 9. Table 9. Planform values for the new channel above Weir Road Belt Width 45-50 feet Meander Length 45-65 feet Radius of Curvature 10-30 feet Stream Channel Dimensions With the removal of flow control structures within the project area, future sea level rise predictions, and planned upgrades to downstream culverts, we expect to see greater tidal influence in our project area post restoration. We designed a channel that is sized for current hydrologic conditions with the ability to adapt to changing and uncertain factors such as rising sea level and intensifying precipitation events. In the headwaters, we observed naturally formed channel segments with four to eight feet top widths. We determined that a cross sectional geometry with a channel top with of six feet and bank height of 1 foot will overtop during the 2-year return period flood. With little sediment supply, the proposed channel continues to have a 6-foot top width through most of the bog upstream of Weir Road. Approximately 200 feet before Weir Road, the channel transitions to a top width of 14 feet and bank height of 1.5 feet. The existing channel downstream of Weir Road has an average top width of 14 feet. While the channel is over-widened and channelized, we concluded the existing channel MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 5 dimensions will allow for the additional flow that comes from the elimination of the main ditch and future sea level rise conditions. The crossing at the footpath between Cheyenne Lane and Knollwood Drive will see the impact of rising tides sooner; therefore, the proposed channel is sized to a top width of 20 feet. We will create floodplain and riparian connectivity to allow for flood waters to spread over the surface of the floodplain, while maintaining pedestrian passage. Channel and Bank Stabilization The proposed channel slopes through much of the restored channel area are less than 0.2%. Therefore, we are not proposing riffle construction or the use of stone in the channel bed or banks. As described above, we propose using large wood to provide habitat along the channel banks in the proposed freshwater systems upstream of Weir Road. This wood will also provide some bank stabilization. Elsewhere, however, the banks will be sloped no steeper than a 2(H):1(V) slope with no additional stabilization measures. The one location of steeper proposed channel slope is upstream of the proposed new pond in the headwaters of the restoration area. This channel section is close to a 2% slope and will be constructed with gravel and cobble with banks made up of a stone toe and fabric encapsulated soil lifts. This channel is steeper to maintain the open water of Miss Thacher’s Pond. 8.6 VEGETATION We propose to replant disturbed areas with native seed and native potted trees and shrubs. In the next phase of design, we will provide a more detailed species list with proposed quantities and locations. Different areas of the site will develop into different vegetative ecosystems: • The wetlands east of the pedestrian path between Cheyenne Lane and Knollwood Drive will be influenced more by tidal flows with the removal of downstream constrictions. Therefore, we propose a mix of salt marsh vegetation species and transitional species that do well in the mixing zone between salt marsh and freshwater wetlands. • In the area of sand removal south of Mill Pond, we recommend planting potted Atlantic white cedar trees • In the disturbed areas between the pedestrian path (that connects Cheyenne Lane and Knollwood Drive) and Weir Road, we recommend a mix of Atlantic white cedar, American holly, and wetland shrubs for the wetland surface. Along the edges in the areas of ditch filling to the east and south of this work area, more upland species such as pitch pine or white oak would be appropriate. • South of Weir Road in the upstream portions of this restoration, we recommend focusing on developing a robust Atlantic white cedar stand with a mix of wetland shrub species. 8.7 RECREATION Current recreation within the project site includes walking and wildlife viewing. Many of the trails are overgrown with some of the stream crossings broken, failing, or not present. Through this MAY 2021 BASS RIVER HEADWATERS RESTORATION 60% DESIGN REPORT 6 restoration project, the project partners would like to improve the walking trails and reconstruct the stream crossings. The existing trails will be cleared of encroaching vegetation and new trails will be developed to encourage more walking and wildlife viewing. Stimson Associates has designed the pedestrian crossings to include the following: • Pedestrian crossing at the location of the existing dam upstream of Weir Road: approximately 10 feet in length; • Pedestrian crossing downstream of Weir Road: approximately 24 feet in length; • Pedestrian crossing at the existing dirt path between Cheyenne Lane and Knollwood Drive: approximately 42 feet in length to accommodate the wider, tidally-influenced channel; and • Pedestrian boardwalk on the eastern edge of the project that will replace portions of an earthen berm that currently extends to Mill Pond.
