Invoicing is completed monthly and is documented to the degree needed by our clients.

RELEVANT EXPERIENCE Dam Removal Design and Plan Preparation Milone & MacBroom has unique experience in the area of dam removal and dam modification and has been involved in over 100 projects in over 10 states with the completed removal of nearly 40 dams. Our staff has conducted feasibility analyses and dam removal and fish passage studies, created preliminary and final designs, and provided construction administration services during the dam removal. We have aided the removal of concrete, masonry, earth, and timber dams for safety, fish passage, habitat improvements, and river restoration. Staff members are frequently invited to speak at regional and national conferences ranging from specific case studies to general river restoration techniques. The firm has planned and designed fish ladders and bypass channels around dams, as well as fish passage ramps at dams that must remain in place. The firm is a recipient of the “Outstanding Organization Award” from the Southern New England Chapter of the American Fisheries Society in recognition of our commitment to restoring fishery resources.

The firm’s design for the Holmes Playground Dam removal is currently under construction in Plymouth, MA with expected completion in 2019. In 2018, Milone & MacBroom dam removal designs were constructed at Rome Dam in Jay, New York, and Blackledge Dam in Glastonbury, Connecticut, while 2017 saw the construction of East Burke Dam removal in East Burke, Vermont. In 2015 and 2016, Milone & MacBroom dam removal designs were constructed at Rattlesnake Brook Dam in Freetown, Massachusetts; the former Ed Bills Dam in Lyme, Connecticut; the Plymco, Off-Billington, and Water Street Dams on Town Brook in Plymouth, Massachusetts; West Fork Dams in Clarksburg, West Virginia; and Boquet Dam in Wilsborough, New York. In 2014, the Franconia Dam in Groton, Vermont, and the Kendrick Pond Dam in Pittsford, Vermont, were removed. In 2013, the Dufresne Pond Dam and Henry Bridge Dam were removed. In 2012, the team oversaw one of the largest dam removals on the East Coast – the Great Works dam removal in Old Town, Maine, on the Penobscot River. In 2011, we completed the Briggsville Dam removal on the Hoosic River in Clarksburg, Massachusetts, and the Wapping Road Dam removal on the Jones River in Kingston, Massachusetts. In all of these projects, the firm was the design engineer of record, having conducted survey through design and permitting, and concluding with construction-phase services and postconstruction monitoring. We have many more constructed dam removals to our credit spanning over the last three decades. Fluvial Geomorphology Team members have specialized experience in applying fluvial geomorphology principals to riverine assessments and restoration projects. The firm uses all three leading quantitative geomorphic analysis techniques and applies them for naturalistic channel design. Our application of Regime Theory, Regional Hydraulic Geometry, and Reference Reaches methods is reinforced by vigorous hydraulic analysis. The project team has performed watershed inventories, stream classification, river reach inspections, bankfull surveys, and identification of problem sites.

Hydrologic & Hydraulic Modeling For decades, Milone & MacBroom has been a leader in flood analysis and mitigation planning. Team members have applied hydrologic modeling experience using HEC-1, HEC-HMS, TR- 20, and WIN-TR-20 along with analysis of gauge data and regression equations. Riverine modeling is routinely conducted with HEC-RAS, HEC-GeoRAS, HEC- GeoHMS, and a variety of two-dimensional hydrodynamic models. The team was a HEC-RAS version 5.0 beta tester, and we are now currently applying the new release on projects in the one- and two- dimensional modes. Our models are developed to meet the technical standards and permitting requirements necessary to comply with FEMA as well as other state and federal agencies.

Sediment Management Sediment survey, characterization, and analysis have been a key element of many of our permitted and constructed fish passage projects. Integral to our staff is Scott Bristol, to assess contaminated soil and sediment. He understands the complex regulations that pertain to sediment management and has led the sediment management efforts on many fish passage projects in New England. Team members have developed technical papers adopted by ASCE on channel evolution and sediments post dam removal.

Wetland Biology Milone & MacBroom has in-house wetland delineation, functional assessment, and field survey as well as wildlife and upland vegetation survey and analysis capabilities. Our certified wetland scientists and wildlife biologist have performed comprehensive surveys and field investigations on thousands of acres of undeveloped land, including vernal pool assessments, studies of threatened and endangered species, microbenthic analysis, and functions and values evaluations. The project team has in-house wetland functional assessment and field survey capabilities utilizing a variety of assessment techniques and established protocols including HEP, HGM, WET, and others. These have been vetted by local, state, and federal review agencies as well as third-party specialists. Our functional assessments have taken place in a variety of environs including urban and rural, tidal and fresh water, and high and low quality. Wildlife Habitat Studies Habitat restoration studies for aquatic and upland components have been conducted on many of our projects, including numerous constructed projects with aquatic, upland vegetation, and wetland communities in addition to listed species. The firm’s professional wetland scientists and ecologists have provided endangered, threatened, and listed flora and fauna specie surveys and assessments on a variety of projects including river restoration and dam removal projects. As part of our work, we have prepared species management plans to help protect listed species including establishment of critical habitat preservation areas, habitat management, species relocation, and construction management plans.

Invasive Species Management The firm’s wetland scientists are experts in invasive plant species management for both upland and wetland invasive species. Our scientists are well versed in management methods and tailor their management plans based on the project’s target plant species and short- and long-term budgets. Our scientists have completed multiyear monitoring events to determine invasive species management success on a variety of projects.

River & Stream Restoration Milone & MacBroom has developed a unique niche in the conceptual planning and feasibility analysis for river restoration and naturalized stream channel restoration projects. Our work has included restoration master planning; bathymetric and upland survey; sediment characterization and management planning; wetland delineation, assessment, creation, enhancement, and restoration; pond dredging; fish habitat design; and dam repair. The project team has worked on dozens of stream corridor habitat restoration projects, partnering with local municipalities, watershed management groups, and regulatory agencies on projects involving engineering analysis, design, and permitting of stream restoration and bank stabilization projects. Our approach to these types of projects considers natural river forms and processes from both physical and biological perspectives. The resulting projects address the restoration and stabilization concerns in addition to providing opportunities to protect or enhance the existing natural resources.

Structural Engineering Our staff of structural, transportation, civil, environmental, and hydraulic engineers have provided bridge inspections and evaluations, permitting, design, and construction inspection of bridge rehabilitation and replacement projects. Milone & MacBroom has successfully designed bridge replacement and rehabilitation projects throughout our firm’s history. The firm has worked in an On-Call capacity to MassDOT providing hydrologic and hydraulic analyses in support of the Accelerated Bridge Replacement Program. Our bridge designs have ranged from large multibridge interstate projects to small local road crossings, many of which have been funded through State DOT and Federal Highway Administration (FHWA) bridge programs. In addition to our bridge work, we have designed countless culverts including precast concrete box and arch culverts. Our in-house capabilities also include bridge inventory and condition inspection, with licensed professionals having FHWA-sponsored program training entitled “Safety Inspections of In-Service Bridges.” The firm designed removal of three roadway/dam outlet structures along Town Brook in Plymouth, Massachusetts, which were replaced with two bridges. Milone & MacBroom was responsible for design and permitting of the bridge replacements and dam removals in addition to supporting services, including construction administration.

Regulatory Permitting Project team members have prepared environmental permit applications and associated documentation and analysis on a wide variety of projects in Massachusetts. Permits at the local, state, and federal levels have been obtained successfully for many unique and challenging projects. Project team members are well-versed in regulatory requirements and state and federal policies regarding stormwater management, environmental resources, wetlands, and floodplain management. The project team has obtained many regulatory review approvals on dam removal projects as well as wetland and stream restoration projects through the Army Corps of Engineers and countless local Inland Wetland Permits at the local level.

Public Outreach Communicating with project stakeholders is one area that sets Milone & MacBroom apart from our competitors. Our engineers, scientists, planners, and landscape architects regularly present project results at stakeholder meetings and dedicated public information meetings. We understand that a project is only truly successful if the stakeholders support its implementation. To that end, we prepare presentations that allow us to describe our technical work in language that the general public can understand. The firm is experienced in preparing presentation materials, including PowerPoint and graphics. The project team can provide comprehensive outreach and moderation services to build consensus and obtain input from various constituencies.

Milone & MacBroom prides itself on our positive track record working with a wide array of project stakeholders. We regularly conduct outreach as project planning and conceptual design begins to relay project information, and we seek design input to create win-win scenarios for various parties to develop consensus on project goals and objectives, and to initiate future funding efforts. Our experience shows that this initial outreach and stakeholder involvement is critical for project success.

Photosimulations and artistic renderings are often accompanied with clear data presentations to illustrate existing and proposed conditions. Project sponsors often turn to our project team to explain project goals and objectives and communicate project need and the background for the preferred alternative. We regularly hold informational and workshop meetings during the conceptual design stage of a project to allow ample time for input and to generate stakeholder involvement that is a primary mechanism to reach consensus around a project.

Public and/or stakeholder involvement is invited by way of publications and media relations, meeting facilitation, and the design and development of stakeholder involvement programs. Projects have included integral web linkage as well. Dam Removal Projects The following table is a summary of constructed dam removals for which Milone & MacBroom was the engineer of record.

*Final project conducted by the Army Corps of Engineers Section 2 Statement of Project Understanding & Approach

53 River Street Dam (MA#03463) is located on the Fort Pond Brook in Acton, MA. The total length of the dam is approximately 185 feet. Previous reports indicate that the maximum height of the structure is 14.5 feet. Multiple spillways and low level outlets discharge to both the downstream channel and a former millrace, which form an island between the downstream channels. A dam inspection report completed in November of 2018 identified the dam as a Significant Hazard dam in “unsafe” condition.

An overarching goal of this dam removal project is to advance the ecological restoration of the river system, eliminate the need for continued maintenance, eliminate the public threat of dam failure, and to improve recreational use and improve ecological function. A benefit of any dam removal is to eliminate the hazard potential of aging dams and eliminate future long-term maintenance costs.

We anticipate the following critical issues may affect the potential dam removal: (1) concern for nearby bridge infrastructure, including potential impacts to bridges, roadways and railroads; (2) other infrastructure, such as the nearby abandoned mill buildings and underground sluiceways in close proximity to the dam and impoundments; (3) sediment quantity and quality; and (4) visual and aesthetic impacts. We will review each issue and others as described below.

Initial Observations and Approach to the Project Our approach to dam removals blends art and science together to design a project that considers the needs of both nature and the community. Ecological success, including fish passage and stream/wetland restoration, is essential, as is meeting the needs of engineering concerns such as channel stability, infrastructure protection, and safe flood conveyance. The overall process of removing unneeded or abandoned dams includes characterizing the project setting, preparing topographic and natural resource maps, studying the watershed’s hydrology and river morphology, performing hydraulic analysis, evaluating dam removal alternatives, obtaining the appropriate regulatory approvals for the selected alternative, and preparing construction documents. Public participation is also often an active part of the process.

Hydrology and Hydraulics Understanding a watershed’s hydrology is critical to the success of river restoration and dam removal projects. We will assess and estimate flood flows to predict channel stability associated with dam removal and the susceptibility of sediment to scour or erosion, as well as “normal” flows that affect fish passage and habitat. Typically, the peak flows for the 2-, 10-, 25-, 50-, 100-, and 500-year events will be evaluated, along with the seasonal and mean monthly average flows to assess fish passage. We propose that existing peak flow data be compiled from existing sources and assessed for validity. The resulting flows will be compiled and compared with previous hydrology that is available from previous dam inspection reports, FEMA studies, USGS Gauges, regional regression equations, and other available sources. A combination of LIDAR (for overland floodplain geometry) and in-water bathymetry survey and measurements of wet-sections and bridge openings will be utilized to develop a brand new HEC-RAS hydraulic model. The model will be used to evaluate the floodplain of the Fort Pond Brook, as well as the effects of removing the 53 River Street Dam. It will also serve as the basis to evaluate bank and sediment stability and fish passability in a post-dam removal scenario. Dam Breach Analysis The peak flows described above will be used along with a regional unit hydrograph to develop a composite hydrograph of a full storm event in the watershed. This will be used in conjunction with the steady-state HEC- RAS model described above to run an unsteady-state dam breach an analysis within HEC-RAS. The results of the dam breach will include the floodplain boundary and inundation extents for the spillway design flow, as well as a sunny day failure of the dam.

Sediment Dams that impound water typically detain and impound sediment as well. A release of sediment over a short period of time can cause sediment to flow downstream and cover the native channel substrate in low-velocity zones. Our sediment management strategies include natural processes (allow erosion of clean material if it will not harm downstream areas); regulated slow release (gradual breach and water drawn down to encourage slow sediment release); limited sediment removal (remove hot spots or pre-form a channel across the pool bottom); relocation (move and relocate sediment, on site, within the footprint of the dry pool site); excavate and remove (usually reserved for contaminated material or excessive volumes); or stabilize in place.

Geomorphic Analysis As part of the initial field investigations, project team members will conduct a geomorphic assessment and evaluate the preferred equilibrium, width, depth, gradient, pattern, and profile features to support the stabilization of a natural channel. Assessment of such channel parameters in the region, and the identification of a stable reference reach can help inform the design relative to Aquatic Organism Passage (AOP) through the post-removal project site. Our geomorphic analysis will consider the river’s bed, banks, and planform shape as a function of natural process. We use empirical site data and theoretical assessments to help ensure the final channel through the former impoundments has the proper slope, width, depth, and alignment to be stable and provide favorable habitat. Determination of equilibrium conditions will then help assess the stability of the river after the dam is removed and the impoundment drained.

Recreational Uses The 53 River Street Master Plan Special Committee is interested in creating a park-like setting at the dam site. A partial dam removal will preserve remnants of the historic dam structure for posterity and educational purposes. The partial dam removal will need to extend beyond the new stream channel banks far enough to allow for Fort Pond Brook to flow unimpeded through the current dam site post removal. The extent of the partial removal will be determined based upon the river hydraulics to fully convey the 100 year design storm without impounding any water behind the former dam site. MMI’s Landscape Architects have been involved with more than a 100 miles of multiuse trail and park projects throughout the East Coast. In Massachusetts, we have conducted work on the Blackstone River Greenway, the Mohawk Trail, and the Chicopee Riverwalk. Our team has received several national awards for “Design Excellence” for the Meriden Green in Meriden, CT. Our Landscape Architects in consultation with our structural engineers have collaborated on numerous park projects that included bridge crossings of rivers or streams. At this site it may be possible to incorporate a new pedestrian observation platform overlooking the river as well as some pedestrian walkways and bridges. These park features may be integrated in conjunction with the existing concrete and stone structures downstream of the dam. Scope of Services The following tasks are proposed based on information presented in the Bid Request, a field visit, the follow-up responses to bidder questions, and our background and experience at similar dam removal sites.

Phase 1: Breach Feasibility Study

Task 1 – Data Collection

Throughout the course of this project, the Milone & MacBroom project manager will coordinate project tasks; perform project-related managerial tasks; receive and execute direction from the Town; schedule work; maintain project records, technical data, drawings, and reports; maintain financial records; and coordinate with project partners. The following specific tasks are proposed:

1.1 Project Kick-Off – At the outset of this project, team members will participate in an initial project kick-off meeting with the Town and project partners to confirm project vision, goals and objectives; and establish a detailed project schedule. We assume this meeting will be held via conference call with a follow-up site visit during scheduled field work. In preparation for the meeting, a project plan and schedule will be prepared that details work activities, sequence of events/milestones, and submittal of deliverables. The plan and schedule will be updated during the course of the project.

1.2 Maintenance of Project Files – Milone & MacBroom maintains a full-time IT team and a paperless filing system that is backed up and stored on a daily basis. We have web capabilities for the transfer and sharing of large files and databases, which we make available to all of our clients at no additional cost. Throughout the course of this project, we will maintain files for work product, including reports, plans, correspondence, meeting notes, drawings, and laboratory results. Such files will be transferred to the Town upon project completion. Reports and compiled final work product will be provided in pdf format. Project base mapping and preliminary design will be provided in pdf and AutoCAD format. Modeling input and output data will be provided as well.

1.3 Review of Existing Resource Materials – Under this task, additional data, mapping, reports, and information will be collected and reviewed as available from the State of Massachusetts Office of Dam Safety (ODS), the Town of Acton, utility providers, other project partners and stakeholders, and state agencies. This information may include dam inspection reports, bridge construction plans, past studies, watershed history, information regarding abutting property owners, information on historical fish runs and/or fisheries, threatened or endangered species, existing archeological or historical reports, mapping of the project area, aerial photographs, natural resource information, geologic data and mapping, hydrologic data and analysis, fisheries data, FEMA data, modeling, and reporting, and sediment data. This will include a review of publicly available information to inform an assessment of the potential for contaminated sediment within the impoundment. A resource listing will be developed.

1.4 Identification of Wetlands and Resource Areas – A Milone & MacBroom wetland scientist will identify, characterize, and flag resource areas within the 6.4-acre parcel owned by the Town and shown on the survey map prepared by Stamski and McNary Inc. dated November 25, 2015 subject to the provisions of the Rules and Regulations of the Massachusetts Wetlands Protection Act and Section 404 of the Clean Water Act. Wetlands will be delineated using the methodology provided in the United States Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and Northeast Region. Resource area boundaries and flags will be collected using handheld GPS and incorporated into project base mapping (Task 1.9). This task includes establishment of data plots and completion of USACE wetland data forms. Wetland delineation will extend from approximately 450 feet downstream of the dam to approximately 900 feet upstream of the dam. Wetland scientists will visually assess and characterize wetlands within the immediate project area. USACE transect forms will be completed, and a GIS map depicting wetland community types will be prepared along with a brief wetland report for future use in MEPA filing. This task also includes research of the Natural Heritage Atlas for priority habitat or listed rare plants and animal species sufficient to determine if dam removal would trigger a Massachusetts Endangered Species Act (MESA) review.

1.5 Topographic and Bathymetric Survey – Undertake topographic survey of the dam and its immediately surrounding area, appurtenances, including the stone piers within the channel and the portion of the watercourse that is impounded. Survey will include bathymetric survey of the Fort Pond Brook, beginning approximately 300 feet downriver of the dam, and extending approximately 2,000 linear feet upriver of the dam to the Main Street Bridge. Upland survey will also be performed to capture the spillways, the stone piers in the channel downstream of the dam, topography surrounding the dam, and visible utilities sufficient for feasibility assessment, including potential construction access and staging areas. The survey will be completed in the state plane horizontal datum NAD 83 and vertical datum NAVD 88. Additional survey may be warranted in future advanced phases of engineering design but is not believed to be essential at the preliminary design level. Field survey and the bathymetry surrounding the dam is critical to hydraulic modeling of the dam removal, to assess the longitudinal profile along the river thalweg, to accurately determine the extent of the channel impacts post-dam removal, and to assess the limits and extents of dam removal necessary for ongoing channel stability and fish passage.

1.6 Impoundment Investigation – Perform an assessment of the impoundment upstream of the dam by boat. Photo-document the condition of the banks, vegetation, flow control structures, intakes, discharges, tributaries, and infrastructure located nearby or affected by the impoundment or its drawdown. Sediment probing will be completed in the impoundment on a regular grid to refusal sufficient for sediment depth mapping, quantifying the volume of mobile sediment above the dam, identifying the top of the impoundment, and to inform the conceptual design. Up to three composite sediment samples will be collected from within the impoundment and analyzed for grain size analysis. Quantification of impounded sediment volume will be computed following field investigations.

1.7 Sediment Characterization – Collect four samples for subsequent analysis of parameters specified in 314 CMR 9.00 including: arsenic, cadmium, chromium, copper, lead, mercury, nickel, zinc, polyaromatic hydrocarbons, PCBs, extractable petroleum hydrocarbons, volatile organic compounds and total organic carbon. Two composite samples will be submitted for testing to characterize the general chemical makeup. It is likely that the water levels within the impoundment will remain down over the summer and the impounded sediment can be accessed without the use of a boat. The labor associated with sample collection is included in the sediment probing in Task 1.6. A third sample will be collected from the stream channel upstream of the impoundment to identify potential background constituents. A fourth sample will be obtained from downstream of the dam in an area where sediment would likely be released, Our in-house Massachusetts Licensed Site Professional (LSP) will review the analysis results relative to the requirements of the Massachusetts Contingency Plan (310 CMR 40.0000).

1.8 Assessment of Site Features – Perform a visual inspection of the dam and areas surrounding the dam, and downstream channel. Site inspection will include the dam, the retaining walls, the surrounding riparian corridor, visible infrastructure, and adjacent properties. Up to two pebble counts will be conducted downstream of the dam to characterize the sediment in the free-flowing channel. Geomorphic assessment of the channel immediately downstream of the dam and upstream beyond the influence of the impoundment will be performed to the extent that natural segments of channel can be located. Bankfull width and depth will be field verified and compared to regional hydraulic geometry curves. The streambed and banks, riparian cover, and channel structure will be noted. Assess the construction of the dam, and measure the spillway height, width, depth, and geometry. Measure and photo-document low flow controls and outlet works. Identify and record visible utilities or other barriers to construction access to the dam and spillway. Measure and document dimensions of the various stream crossings (bridges and culverts) within the limits of the project reach for use in modeling.

1.9 Project Base Mapping – Using MassGIS LiDAR data and field survey collected in Task 1.5, a base map will be compiled at a scale of 1” = 40’ with 1-foot contour intervals where field data has been collected, and LiDAR data with 2-foot contour intervals. Base mapping will include detail on the dam spillways, the impoundment, and surveyed areas surrounding the dam, as well as a swath of topographic data beginning at the Main Street Bridge and extending approximately 2.4 miles downstream to the Laws Brook Road bridge, and sufficiently wide to cover the floodplain of the brook to model the dam breach analysis described later in this scope.

Task 2 – Hydrologic and Hydraulic and Dam Breach Analysis

This task includes a detailed hydrologic and hydraulic (H&H) analysis of the dam, Fort Pond Brook, and the impoundment. The analysis will be used to predict the effects of dam removal, as well as to assess the impacts of a catastrophic dam breach on the downriver areas.

2.1 Hydrologic Assessment – Compile the available MassGIS contributing drainage basin data and USGS StreamStats watershed data, along with an assessment of the watershed boundary using watershed characteristics such as land use, surficial geology, urbanization and impervious area, presence of dams and other flow control structures, and other factors influencing the hydrology at the dam site. FEMA flow information will be compiled from the currently effective Flood Insurance Study (FIS). A Bulletin 17b assessment will be run using the HEC-SSP software package for the nearby gauge on the Assabet River, Gauge No. 01097000 near Maynard, MA to assess peak flood flows. The results will be transferred to the project site using the watershed transfer equation and compared with the FEMA and USGS Streamstats flows. Mean monthly and other low flows will be computed at the site based upon the USGS gauge for the purposes of fish passage evaluation and assessment of typical flows during the construction season. The statistical 15%, 50%, and 85% chance of exceedance flows will be computed for each month, as well as the 7Q10 drought flow, and the bankfull flow. 2.2 Existing Conditions Hydraulic Assessment – Preliminary hydraulic assessment will be performed using the flows obtained in the hydrologic assessment. The assessment will use the USACE software HEC-RAS to develop a one-dimensional hydraulic model to simulate flood flows and low flows at the site. The model will be created using LIDAR topography in the overland areas, and bathymetric data collected inside the impoundment and downriver of the dam will be utilized to create the in-water geometry. Roughness values will be input based upon engineering judgement and field conditions as identified by the site assessment.

2.3 Post Dam Removal Hydraulic Assessment – The existing conditions modeling developed in Task 2.2 will be modified to reflect full removal, partial removal, or breaching of the dam, including ancillary work to the dam removal (such as sediment removal/management, channel construction, bank armoring, etc.). The model will iteratively be used to develop a concept (25%) design of the post-dam removal channel, as well as to size the horizontal and vertical extents of the dam breach and removal. In order to comply with ODS, a dam breach must be large enough to safely pass the 1 percent design storm (100-year) with no ponding behind the former structure in order to be removed from the ODS jurisdictional list. In many cases the entire dam structure does not need to be removed to meet this requirement.

2.4 Channel Stability Assessment – Geomorphic measurements such as channel width, depth, and slope that are captured during the site assessment will be verified with regional data, as well as computationally with the Stable Channel Design calculator inside HEC-RAS. The characteristics of a stable reference reach (as identified in the field) will be compared against the post-dam removal channel configuration to evaluate various dam removal considerations and concerns identified during the feasibility assessment process such as the size of the post-dam removal channel, horizontal limits and vertical extents of the dam breach and removal, post-dam removal velocities, general channel and bank stability, fish passage implications, and potential impacts to nearby infrastructure.

2.5 Dam Breach Assessment – Utilize the HEC-RAS model prepared as part of the Existing Conditions Hydraulic Assessment (Task 2.2) as a basis for developing a dam break analysis. This hydraulic modeling analysis will simulate the catastrophic and sudden failure of the dam to estimate the severity and extents of flood damage on homes, buildings, and infrastructure at risk of inundation downriver. The dam break analysis will consider failure scenarios that occur during a “sunny day” (normal) condition as well as during a flooding event known as a “stormy day” failure. For an existing small, significant (Class II) hazard potential structure, the stormy day failure is analyzed during the 100-year flood. The hydraulic model will be used to route the flood wave resulting from the dam failure through the downstream channel to establish estimated inundation areas to be used for preparing an Emergency Action Plan (EAP). The dam breach assessment will begin at the dam, including the impoundment, and will carry downstream to the Laws Brook Road crossing, a distance of approximately 2.4 miles.

2.6 Report – Prepare a report of the hydrologic, hydraulic, and dam breach analyses, with a summary of the results, options, risks, opportunities, and a recommended path forward. The report narrative will identify the models employed, the input data sets and their sources, and the outputs in both tabular and graphical format. The draft report will be provided to the Town in Microsoft office format, with one hard copy and an electronic copy for distribution.

2.7 Public Meeting – Prepare for and attend a meeting with the 53 River Street Committee in an open session to present the results of the analysis as well as report findings and recommendations. Phase 2: Conceptual Design for Dam Breach or Removal

Task 3 – Concept Dam Removal Assessment

3.1 Concept Design Plan (25%) – Prepare Preliminary Design plans of the dam removal or breach to approximately 25% completion, including the horizontal and vertical extent of dam removal, channel work, and regrading. The plans will depict the site location; plan view of existing conditions showing elevations, physical features, and the extents of regulated areas (i.e., on-site wetlands, ordinary high water, etc.); plan view of proposed conditions in areas to be altered; proposed conditions in the channel; section views of the channel; and typical details. Specifically, the plans will include the following:

•• Title sheet •• Beginning and end of project and project limit lines •• Existing conditions, including titles of adjacent roadways and watercourses; location of utilities, drainage facilities, and associated appurtenances; delineated wetlands; and related information compiled from existing maps and records •• Plan view and longitudinal profile of existing channel and crossings in the project area •• Proposed improvements, including plan view of proposed channel •• Proposed grading •• Typical cross sections •• Standard design details

3.2 Feasibility Study – Prepare a feasibility study outlining the data collection and findings from the prior tasks as well as recommended design approaches and rationale. The report will accompany the design plans in Task 3.1 and will specifically outline the sediment management and stabilization approach, along with key design elements, a summary of anticipated permitting needs (local, state and federal), and identification of key resources. Submit draft materials to the Town for review and address in a single round of comments. Prepare a final memorandum to reflect comments received.

3.3 Public Meeting – Prepare for and attend a meeting with the 53 River Street Committee in an open session to present the results of the work to date. The concept dam removal design will be presented as well as the information gathered in the technical memorandum. Phase 3: Emergency Action Plan

This Task assumes that the current Significant Hazard classification of the dam is appropriate and no reclassification is warranted since the goal of the project is to remove the dam and ultimately reduce the hazard classification to non-jurisdictional.

Task 4 – Emergency Action Plan

4.1 Inundation Mapping – Based on the results of the Dam Breach Assessment in Task 2.5, prepare inundation mapping along a 2.4 mile stretch of the Fort Pond Brook from Main Street to Laws Brook Road showing the areas at risk for flooding during the “Sunny Day” (normal conditions) and “Stormy Day” (100-year flood event) scenarios. Inundation mapping will include critical information at key locations downstream regarding the potential flooding such as estimated flood wave arrival timing and roadway overtopping depths. Mapping will also include information regarding potential evacuation zones, suggested evacuation routes, road closure, and the location of the Emergency Operation Center (EOC) to be established if a dam failure is imminent. The mapping will be based upon the most recent LIDAR and aerial photography available, and will include cross section locations, road labels, waterbody and watercourse labels, and parcel data with parcel IDs.

4.2 Emergency Action Plan (EAP) – Develop an EAP to reflect the updated hydrologic and hydraulic analysis prepared under Task 2 above and does not include a HEC-HMS model of the entire Fort Pond Brook watershed. The EAP will include inundation mapping, as well as guidance for local officials on roles and responsibilities, monitoring and emergency level determinations, notification/ communication and evacuation procedure, and other requirements in accordance with Mass ODS. MMI will follow the EAP template provided by the Mass ODS and work closely with State Dam Safety Engineers to ensure the EAP contains the information needed to compile with State Regulations. In general, the EAP will provide information regarding, but not limited to, the following:

•• Critical information about the dam including sketches / plans / sections •• Notification procedures including notification flowchart(s) •• Emergency detection, evaluation, and classification info •• Summary of impact areas with road closure and evacuation info •• Event termination and recovery procedures •• Inundation Maps •• List of available materials and equipment •• Common dam safety definitions

A copy of the EAP will be submitted to the ODS and MEMA in electronic and hardcopy (1 copy each) format. In addition, EAP will be provided to the Town in electronic and hardcopy format. Electronic files used to generate the inundation mapping such as GIS shapefiles will be submitted to the ODS and MEMA along with the EAP.
