Upper Hathaway Brook Dam Removal Project

Massachusetts, Dalton

73.185051° W

42.420565° N

The presence of the deteriorated and now-abandoned Upper Hathaway Dam has resulted in the loss ofaquatic habitat, stream continuity, and natural sediment transport within a portion of Hathaway Brook.Hathaway Brook is a tributary to Sackett Brook, which in turn is a tributary to the Housatonic River.This project proposes to remove the Upper Hathaway Dam and to restore stream continuity, whichwill allow migration of brook trout (Salvelinus fontinalis) and other aquatic organisms from theHousatonic River to the upper reaches of Hathaway Brook; restore natural flow patterns; reestablishnatural sediment and nutrient transport; improve water quality; and enhance habitat value and long-term sustainable benefits for aquatic organisms.

Part C. Project Narrative

PART B. PROJECT ABSTRACT

The City of Pittsfield is seeking to restore stream connectivity and aquatic biological resource habitat

within Hathaway Brook by removing Upper Hathaway Dam located in Dalton, Massachusetts within the

Housatonic River watershed. The deteriorating Upper Dam impounds Hathaway Reservoir and is part of

a water supply for the City that is no longer in service. The City is required by MassDEP to remove

Lower Hathaway Dam, located 250 feet downstream of Upper Dam, as a compensatory mitigation project

for the repair of Ashley Lake Dam. No Housatonic River NRD Funds are being requested for this project.

Although not required by MassDEP, the City has proposed removing Upper Dam in addition to Lower

Dam, recognizing its removal would allow for the full benefits of stream connectivity. The project goals

are to restore connectivity of Hathaway Brook and allow migration of brook trout and other aquatic

organisms from the Housatonic River to the upper reaches of the brook; restore natural flow patterns;

reestablish natural sediment and nutrient transport; improve water quality; and enhance habitat value and

long-term sustainable benefits for aquatic organisms. Project activities include: removal of the Upper

Dam wall, removal of a portion of the impounded sediment, re-grading, and reestablishment of streambed

characteristics. Total project cost is anticipated to be $850,000, of which $500,000 of Housatonic River

NRD Funds are requested. The Upper Dam Removal Project is anticipated to occur in conjunction with

the Lower Dam Removal Project in late summer/early fall of 2010 and require three months to complete.


PART C. PROJECT NARRATIVE

The City of Pittsfield is seeking to restore aquatic biological resource habitat within Hathaway Brook byremoving Upper Hathaway Dam and reestablishing stream connectivity. Hathaway Brook is a tributary toSackett Brook, which in turn is a tributary to the Housatonic River. As a compensatory mitigation projectrequired by MassDEP for unavoidable wetland impacts as a result of the repair of Ashley Lake Dam, theCity of Pittsfield is required to remove Lower Hathaway Dam which is located on Hathaway Brookapproximately 250 feet downstream of Upper Hathaway Dam. Although not required by MassDEP, theCity is proposing to remove Upper Hathaway Dam and its appurtenant structures as a separate project (thesubject of this application package). The dam and Hathaway Reservoir, built in 1908, no longer functionas originally intended. Since its use as a water supply was abandoned in the late 1950s, the dam hasseverely deteriorated and currently presents a potential hazard to pedestrians and wildlife that encounterit. Brook trout (Salvelinus fontinalis) have been observed in Hathaway Reservoir; however, habitat valuehas diminished in the vicinity of the Hathaway Reservoir impoundment and the stream reach between theLower and Upper Dams.

1. Project Goals and Objectives

The primary goal of the Upper Hathaway Dam Removal Project is to restore natural streamconditions and stream connectivity within Hathaway Brook, thereby enhancing habitat value forexisting aquatic species and allowing migration from the Housatonic River to the upper reaches of thebrook. The objectives of this project are to:

� Remove the barrier to approximately 18,000 square feet of stream habitat for brook trout andother aquatic organisms;

� Recreate pre-dam topography in upland areas and the historic stream channel;� Reestablish continuous flow and natural sediment transport regime, and restore river

geomorphic processes within channel, to that which currently exist upstream of the existingimpoundment and downstream of the Lower Dam; and

� Create a small pool habitat area to encourage brook trout spawning for long-term benefits.

2. Project Benefits

Removal of Upper Hathaway Dam (the subject of this application package) in addition to the plannedremoval of Lower Hathaway Dam would result in immediate benefits. Both the Massachusetts Divisionof Fisheries and Wildlife and the Riverways Program support the removal of Upper Hathaway Dam inconjunction with Lower Hathaway Dam to improve stream connectivity within the sub-watershedbenefiting the native fluvial fishes (see “Letters of Support and Agency Correspondence” attachment).Removal of Upper Hathaway Dam will result in the following natural resource benefits:

Surface Water: Dam removal and stream restoration will positively impact water quality by: reducingwater temperatures, establishing natural dissolved oxygen levels, establishing more natural base flows andimproving water and river bottom sediment quality.

Biological Resources: Dam removal will positively impact fish, invertebrates, amphibians, and otherwildlife by establishing continuity of aquatic habitat. Establishment of a natural river bank will alsoimprove canopy conditions, enhance wildlife migration along the river corridor and ameliorate watertemperature conditions.

Sediments: Stream restoration will improve general biological function. Dam removal reestablishes anatural sediment transport regime and restores natural river geomorphic processes.


3. Project Implementation Plan

Description of Current ConditionsUpstream of Upper Hathaway Dam, Hathaway Brook consists of a 15 foot-wide channel that provideswater flow into Hathaway Reservoir. A former stream bed that may have also carried water to HathawayReservoir is separated from Hathaway Brook by a large depositional feature. A fallen tree also blocks thisabandoned stream bed from the reservoir, forming a natural bank. Since the Upper Hathaway Dam andReservoir no longer function as originally intended, conditions have degraded. Over the last 100 years,Hathaway Brook has deposited a significant volume of sediment into Hathaway Reservoir resulting in acurrent water depth of approximately 1 to 3 feet.

The Upper Hathaway Dam was built in 1908. The Dam is 157 feet in length, 5 feet 2 inches in width atthe crest and 22 feet high. The dam is severely deteriorating with exposed rebar and water leaking belowthe spillway. There is also an abandoned gatehouse approximately 10 feet by 12 feet, with screens andstop logs in the well of the gatehouse, but no control structures.

Downstream of Upper Hathaway Dam, Hathaway Brook traverses a length of approximately 250 feetbefore reaching Lower Hathaway Dam. The stream bed width between Upper Hathaway Dam and LowerHathaway Dam varies between approximately 10 and 40 feet; however, islands in the center of the streambed force water flow into two approximately 10 foot wide channels on either side of the islands in twolocations within the reach.

No discernible impoundment area exists between the Upper and Lower Dams. Lower Hathaway Dam isapproximately 75 feet long by 6 feet high with a 3-foot wide crest. A 3-foot by 3-foot intake box thathouses a screen chamber is located on the upstream face of the dam. The water that is collected in theintake box currently runs through a pipe that discharges approximately 50 feet downstream of the LowerDam at a headwall forming a secondary branch of the stream. Downstream of the Lower Dam, HathawayBrook becomes a uniform channel of approximately 10-15 feet wide.

Hathaway Brook upstream and downstream of the two dams includes both pool and riffle habitats, withmajor habitat features including boulders and very large cobbles. On average, water depths wereobserved to range from a few inches in riffles to 12 inches in some of the pools during site investigationsconducted in October 2008 and February 2009.

Existing banks in this area are extremely steep, with bedrock outcroppings evident throughout the areaand little vegetation along the banks below bankfull indicators.

See the “Supporting Technical Documentation” attachment for photographs of existing conditions.

Description of Desired Future ConditionsThe desired future condition for Hathaway Brook is a stream with a contiguous, gradual slope passable bybrook trout and other fish species. It is anticipated that under future conditions, continuous flow inHathaway Brook achieved as a result of removal of both dams (the removal of Upper Hathaway Dam isthe subject of this proposal package) will serve to reestablish natural sediment transport and geomorphicprocesses in this reach similar to that which currently exists upstream and downstream of the dams.Excavated sediment on-site will be used to fill the abandoned channel upstream of the Upper Damenhancing upland habitat.

The bottom of the stream channel will be lined with cobbles after grading is complete to create astreambed amenable to brook trout. Post-grading bank treatment will similarly include cobbles andboulders to stabilize stream banks. A small pool habitat will be accessible by Brook Trout to encourage


spawning. Based on consultation with MA Riverways, it is anticipated that the stream will also rearrangeexisting material to create natural step pool and cascade morphology.

Planting will contain only native and indigenous plant materials to the region, including eastern hemlocksaplings and American beech saplings. Future conditions will achieve canopy vegetation similar to thatwhich currently exists in other locations along Hathaway Brook. See the “Supporting TechnicalDocumentation” attachment for plans of the proposed project.

a. Implementation ApproachThe overall approach for this project is to restore stream connectivity and enhance habitat value withinHathaway Brook by removing Upper Hathaway Dam in conjunction with the removal of LowerHathaway Dam. This approach builds extensively on research and feasibility studies that are beingcompleted for the removal of Lower Hathaway Dam as a mitigation project required by MassDEP.

� Work will be done in late summer to early fall to take advantage of low flow conditions.Construction activities need to be initiated by August 31, 2010 to be consistent with the schedulefor the Lower Dam removal project. The actual start date for construction will be dependent onthe time required to obtain the environmental permits for the project and the environmentalconstraints that could be placed on the project.

� Although this proposal focuses on the removal of Upper Hathaway Dam, the removal of LowerHathaway Dam is anticipated to occur simultaneously.

c. Major Phases and Milestones1. Dam Removal Feasibility Study – A feasibility study was completed for the proposed project. Thefeasibility study consisted of detailed topographic and bathymetric survey, physical and chemicalsediment characterization, sediment depth probing, resource area and aquatic habitat evaluation,hydrologic and hydraulic modeling, and consultation with Massachusetts Historical Society. The


feasibility study also included developing preliminary design documents consisting of design drawings,and a sediment management plan. Preliminary design drawings consisted of an existing conditions plan,site grading plan, pre- and post-construction cross sections, a pre- and post-construction longitudinalsection through the deepest part of the stream channel, and a stream bed restoration plan. The restorationdesign included incorporation of important habitat features as part of the new streambed, such as a pooland overhanging vegetation, in order to maximize the benefits of the dam removals. During developmentof the preliminary design documents, the City and its consultant, AECOM, consulted with the MARiverways Program, MassDEP, MA Natural Heritage and Endangered Species Program, and the USArmy Corps of Engineers.

2. Final Engineering – Final engineering for removal of Upper Hathaway Dam (the subject of thisproposal package) will be completed as part of the mitigation plan for removing Lower Hathaway Damassociated with the Ashley Lake Dam Repair Project. The Expected completion date for the final designdocuments is June 30, 2009. The engineering plan consists of full dam removal and beneficial reuse ofexcavated sediment on-site in upland areas. Excavated material exceeding the amount used for restorationwill be disposed of off-site in an approved Massachusetts landfill.

3. Permitting – Filing of the permits outlined in Part D is anticipated to occur in summer/fall 2009.

4. Dam Removal – The entire dam and appurtenant structures will be removed.

5. Sediment Removal – Sediment will be removed with conventional construction equipment such asexcavators during low flow conditions. Approximately 2,930 cubic yards of excavated sediment areexpected to exceed the on-site needs and will be disposed at an approved Massachusetts landfill.

6. River Restoration – The stream channel and bank areas will be restored, including vegetation plantings.Excavated sediment will be used to fill in the abandoned stream channel upstream of the existingHathaway reservoir impoundment.

7. Construction Monitoring – This activity will be the responsibility of the on-site engineer.

8. Pre- / Post-Restoration Monitoring – Cross-sections and longitudinal profiles have been collected andpre- and post-hydraulic conditions have been modeled. Future hydrologic/hydraulic conditions and thestorage-depth relationship for the current impoundment upstream of the Upper Hathaway Dam wassimulated in the HydroCAD model to predict any adverse changes to the downstream flow conditions as aresult of the removal of the dam. In addition, anticipated flow velocities and water levels achieved afterthe dam removal for cross sections at six locations along the brook were simulated using HEC-RAS, ariver modeling software program developed at the Hydrologic Engineering Center (HEC) for the ArmyCorps of Engineers. Simulations include conditions during a 2-year storm and 100-year storm.

In addition to the modeling, fish monitoring will occur within the impoundment, in an upstream streamreach, and in a downstream reach both before and after dam removal to assess fish usage of HathawayBrook prior to dam removal as well as after removal. Fish monitoring will occur using a backpackelectrofishing unit and the three-pass removal method. This monitoring will be completed in fall 2009 todocument pre-dam removal conditions and will also be conducted post construction in FY 2012 andFY2013.

d. Required AgreementsAlthough the project area and dam structures are owned by the City of Pittsfield, preferred site accesswould require use of privately-owned land. The City is currently negotiating with the property owner to


utilize an existing path and locate a staging area on the privately owned parcel. Environmental permitsand/or regulatory permits approvals for the proposed project are outlined in Part D.

e. Long-Term Effectiveness and SustainabilityAbandoned dams or dams that no longer serve a useful purpose are notorious for lack of upkeep and areoften under threat of failure. Full dam removal of Upper Hathaway Dam will reestablish natural, self-sustaining river processes that will effectively achieve the natural resource goals of the MassachusettsSubCouncil. To ensure long-term effectiveness and sustainability of the project, a site-specific monitoringplan will be implemented. This plan is detailed in Section 5 below.

All construction methods for stream and habitat restoration within the project area are implemented forthe purpose of long-term effectiveness and sustainability. Restoring continuity in the riverine system willbenefit fish and other aquatic species that are currently restricted from these additional habitat areas.

Brook trout prefer a rocky or cobbly substrate relatively free of silt and sediment. Removing the dams inHathaway Brook will remove an impediment to flow which causes sediment deposition andimpoundment. Removing Upper Hathaway Dam will result in the removal of impounded sediment, andwith continuous flow, encourage natural sediment dynamic processes and nutrients to flow downstreamimproving conditions for brook trout.

The stream and habitat restoration practices include post-grading bank treatment with cobbles andboulders to stabilize banks. Islands within Hathaway Brook that may be disturbed will be seeded with anerosion control seed mix, covered with an erosion control blanket, and planted with materials native to theregion to provide short-term stabilization and erosion control, and provide valuable long-term riparianhabitat. In addition, the stream restoration will include the creation of a pool habitat area to encouragebrook trout spawning, which will contribute to brook trout population growth and long-term sustainabilityof aquatic resources in the brook.

f. Coordination and Integration with Other Ongoing or Planned Restoration ActivitiesThe City of Pittsfield is proposing to remove the Upper Hathaway Dam as a separate project beyond anexisting mitigation project required by MassDEP. As mitigation for the loss of wetlands due toconstruction activities associated with the City’s separate Ashley Lake Dam Repair Project, the City willremove Lower Hathaway Dam and restore stream conditions eliminating a barrier to 250 feet of streamhabitat for brook trout and other aquatic organisms. Although it is not required by MassDEP, the Cityrecognizes that additional benefits can be achieved by removing Upper Hathaway Dam and reestablishingstream connectivity. This project will free an additional 18,000 square feet of habitat upstream of UpperHathaway Dam and allow for downstream migration for fish species and other aquatic organisms. TheMassachusetts Division of Fisheries and Wildlife supports this project stating that “Restoration carriedout on small streams can have immediate benefits” (see “Letters of Support” attachment), and thatremoving the Upper Dam in conjunction with the Lower Dam will improve stream connectivity withinthe sub-watershed which benefits native fluvial fish. Similarly, the MA Riverways Program supports theHathaway Dam removal project stating that “Removing dams from small coldwater streams [such asHathaway Brook] is particularly important as these streams are frequently the last high-quality refugiahabitat in the watershed. Furthermore, these streams supply clear, cool water to larger streams” (see“Letters of Support” attachment).

g. Complementary Planning EffortsHousatonic River Restoration Plan, 1999: Housatonic River Restoration Plan strongly supports theremoval of the Hathaway Dams with the following statement:


Watershed and River Management: “The development of the Housatonic River, its floodplain, andwatershed has created an array of artificial barriers to its natural restoration. These include theconstruction of more than a dozen dams, the presence of many dumps and trash sites along its riverbanks,and the widespread development of its watershed. The restoration effort should attempt to address and asmuch as possible mitigate the impacts of these factors.”

The Commonwealth of Massachusetts, Executive Office of Energy and Environmental Affairs iscommitted to restoring riverine flows and aquatic habitat in the Commonwealth of Massachusetts. Thiscommitment encourages the removal of out-dated dams that no longer serve the purpose for which theywere built.

4. Technical/Technological Feasibility

a. MethodsThe process of dam removal relies heavily on planning and project management. The actual dam removaland sediment management implementation will only take a portion of the total time and resourcesdedicated to the complete restoration effort. The process of dam removal is not formulaic; rather, it isunique to each site. Oversight and leadership are key attributes of steering a project towards success andmeeting the challenges of coordinating multiple tasks and contracts for engineering, construction,permitting and monitoring. The Upper Hathaway Dam Removal Project has a core group of projectpartners with a distinct project lead for the dam removal component of the project. Bruce Collingwood(Pittsfield Commissioner of Public Works and Utilities) will serve as the contract and grant administrator;technical support and project management will be provided by staff from the City’s consultant, AECOM.This team brings together experience in dam removal with local expertise and knowledge. The City ofPittsfield will provide overall project administration for the comprehensive planning and implementationof the project.

Technical methods for dam removal are well documented and have been used across the country to meetaquatic restoration targets. Physical de-construction of structures is commonplace, and many of the sametechnologies used for upland structural demolition are also employed for dam removal. Demolition of theUpper Hathaway Dam will be done in late summer to early fall to take advantage of low flow conditions.Flow within Hathaway Brook will be bypassed around the structure by placing sandbags upstream of thedam to isolate it from the surface waters of Hathaway reservoir and then using either pumps or passivegravity flow to direct water out of Hathaway Reservoir and downstream of the dam. As flow is bypassed,the impoundment will be dewatered. A portion of the reservoir will be used as a sedimentation basin priorto discharging flow downstream. Any accumulated sediment will be excavated at the conclusion of thedewatering and managed in conjunction with other excess excavate. As the impounded sediment isexposed, the sediment and, in turn, the dam wall will be removed using conventional constructionequipment such as an excavator.

b. Successful use of the Approach and/or MethodThe Commonwealth’s first proactive dam breach took place in the Housatonic watershed in Dalton in2000. Crane and Co. working in partnership with MA Riverways Program breached the 200 year old, OldBerkshire Mill Dam on the East Branch of the Housatonic River. The project posed a multitude oftechnical challenges, including: the discovery of an older timber crib dam above the former dam, theprotection of an in-stream water line, bridge abutment protection, extensive sediment sampling andeducation of stakeholders. Despite these challenges the project was completed in just over a year and ahalf. Adjacent to the Housatonic watershed in the Westfield Basin, the Silk Mill Dam was removed in2003 under the direction of MA Riverways Program and the Town of Becket. The dam, on Yokum Brook(a tributary of the West Branch of the Westfield River), was 93 feet long and 15 feet high and was


constructed of stone and concrete. The dam removal required excavating 1,600 yards of sediment. Thisproject was considered successful for trout and salmon restoration and is highlighted by American Rivers.

The MA Riverways Program currently lists at least eleven stream restoration projects that involve damremoval as priority projects.

c. Certainties and Uncertainties with Innovative ApproachesWhen a dam is removed, impounded sediment may become unstable and erode, transporting downstream.Restoring continuous flow to a channel may change stream characteristics and channel configuration. Apreliminary engineering study and sediment sampling and analyses have been conducted for the proposedUpper Hathaway Dam Removal Project to minimize uncertainties and challenges which are oftendiscovered during the initial phases of dam removal projects. The engineering study included a survey ofthe area, and measurements along a longitudinal profile and multiple cross-sections along the brook. Thedata were used to model pre- and post- stream conditions to assist in the development of a streamrestoration plan. Future hydrologic/hydraulic conditions were modeled to determine the storage-depthrelationship for the current impoundment upstream of the Upper Hathaway Dam to predict any adversechanges in downstream flow conditions as a result of the removal of the dam. Furthermore, sedimentsampling and a geotechnical evaluation have confirmed that use of the sediment on-site and off-sitedisposal of excess sediment at a landfill are feasible. The plans are based on the model results, studies andevaluations to eliminate uncertainties, and minimize unexpected adverse impacts.

d. Uncertainties regarding technical/technological feasibilityElimination of uncertainty is best achieved by comprehensive engineering and adaptive management. Afeasibility study has been completed for the mitigation plan associated with the removal of the LowerHathaway Dam. The study also considered the removal of the Upper Hathaway Dam. Included in thestudy are a topographic survey of the site, and an analysis of sediment impacts, flooding and habitatimpacts associated with the dam removal. The dam removal and restoration plans were developed withconsideration of the results of the feasibility study and existing topography in order to mitigate impacts,eliminate uncertainties and provide a natural and functional habitat for a variety of aquatic and terrestrialspecies.

e. Potential technical/technological complicationsThe potential for a bedrock ledge just upstream of the Upper Hathaway Dam, or other naturalimpediments to fish passage upstream of the Upper Hathaway Dam have been discussed. If the bedrockledge exists in the location of the Upper Hathaway Dam, future conditions will not include the contiguousgradual slope planned. However, the dam removal will still benefit aquatic and terrestrial species byrestoring a stream channel with natural sediment transport and river geomorphic processes, improvedwater quality and stream connectivity. The City and staff from the city’s consultant AECOM, togetherbring experience in dam removal and local expertise that allows for an adaptive management approach toaddress cooperatively and effectively any unexpected issues or complications.

5. Monitoring/Evaluation and Contingency Plan

As required, the project proposes to monitor one structural and one functional parameter to provide anobjective evaluation.

PROTOCOL FRAMEWORK FOR STRUCTURAL PARAMETER– Hydraulics: Given that the goal ofthe restoration is to reestablish natural hydrological conditions, a comparison of pre- and post-hydrologic/hydraulic conditions has been modeled for the key structural parameter. Pre- and post-damremoval hydraulics has been modeled using HydroCAD and HEC-RAS. HydroCAD is a hydrology andhydraulics modeling system used for watershed analysis and design. HEC-RAS is an industry standard


river modeling software program developed at the Hydrologic Engineering Center (HEC) for the ArmyCorps of Engineers.

Since the City of Pittsfield’s intention is to remove both dams at the same time, the futurehydrologic/hydraulic conditions were modeled assuming that both dams were removed. The storage-depthrelationship for the current impoundment upstream of the Upper Hathaway Dam was simulated in theHydroCAD model to predict any adverse changes in downstream flow conditions as a result of theremoval of both the upper and lower dams. For the 100-year storm, the simulated flow entering theimpoundment was 276.36 cubic feet per second (cfs), and the flow exiting was 276.12, a change of only0.24 cfs. Thus, removing the impoundment is projected to have no impact downstream. Theimpoundment at the spillway elevation is 0.34 acres, which is 1800 times smaller than the watershed areaof 625 acres. Because the drainage area is much larger than the impoundment (1800:1), removing theimpoundment will have little impact on stream flows downstream.

Based on cross-sectional measurements at six locations along the brook, HEC-RAS was used to simulateanticipated flow velocities and water levels, achieved after removal of both the Upper and Lower Dams.The HEC-RAS results indicated that water elevations in the stream under baseflow conditions would bevery low, equating to only a few inches of water, which is similar to water levels observed during sitevisits in October 2008 and February 2009. During the 2-year storm, which would be roughly equivalentto bankfull conditions, water levels rise to six to 12 inches. Even during 100-year storm events, water ispredicted to remain within the stream channel.

Longitudinal profiles and cross sections at the project site will be resurveyed in FY2012, FY 2013, andFY 2015 to document the stability of the stream channel.

PROTOCOL FRAMEWORK FOR FUNCTIONAL PARAMETER- Brook Trout and Other Fish Species:A major benefit to removing Upper Hathaway Dam is restoring stream connectivity and habitat to brooktrout and other aquatic organisms in Hathaway Brook. As the functional parameter, a fish monitoringstudy will be implemented using pre and post dam removal fish sampling via a backpack electrofishingunit. (Note that macroinvertibrate sampling may be substituted for the electrofishing effort.) Brook troutare known to move upstream during the fall spawning months, and at other times movement is relativelystagnant. Therefore the study design will incorporate a program to conduct electrofishing in October orNovember of the year prior to dam removal (FY 2010) as well as years 1 and 2 after removal (FY 2012and 2013). Fish will be collected using a backpack electrofishing unit and the three-pass removal methodto sample an upstream stream reach, downstream reach, and at the location of the impoundment itself.Approximately 20% of the available fish habitat upstream of the current impoundment will be sampled, aswell as a similar area of habitat downstream. Fish collected will be temporarily stored in buckets on-sitewhile data is gathered regarding their species, weight, and length; all individuals will then be returned tothe stream. Collected data will be compiled and analyzed to assess population densities and size structureboth before and after dam removal.

6. Qualifications of Applicant and Project Team

a.Technical CapacityThe City’s consultant, AECOM, will manage the technical aspects of the proposed project. Withspecialized expertise in water resources and environmental management, AECOM offers comprehensiveplanning, evaluation, permitting, design, and construction services to local municipalities, the federalgovernment, and private industry. AECOM has over 950 employees in the Northeast, with offices inWakefield, Westford, and Concord, Massachusetts, as well as in other New England states.


Developing and implementing fisheries and aquatic habitat assessments and providing technicalassistance in other natural resource management areas are core AECOM services. AECOM’s integrationof fisheries biologists, environmental scientists, and engineers provides an exceptional capability fordeveloping restoration solutions and thus enhancing fisheries and aquatic resources.

For example, AECOM is currently conducting final design and permitting for flood control and streamrestoration in Peabody, Massachusetts. The firm is also assisting the Massachusetts Department ofConservation and Recreation in the assessment of over 200 of its dams with regard to current conditionand use and opportunities for removal and stream restoration. AECOM performed a feasibility study forthe city of Franklin, Tennessee, to assess issues associated with potential removal of a low-head dam onthe Harpeth River. Major components of these projects include flood studies, sediment characterizationand transport modeling, and analyses of wetlands and fisheries habitat impacts.

AECOM has worked closely with regulators at federal, state, and local levels and has coordinated with avariety of stakeholders and developed and managed public outreach efforts. Project experience rangesfrom relatively small projects in terms of geographic area and scope of work to more complex effortsrequiring more significant allocation of technical expertise and staff resources. Resumes of key AECOMstaff that will provide technical support for the proposed project are provided in the “Resumes”attachment.

b. Administrative CapacityOverall project and grant administration will be the responsibility of Bruce Collingwood, Commissionerof Public Works and Utilities for the City of Pittsfield. Mr. Collingwood is a licensed ProfessionalEngineer and has over 25 years of professional engineering and project administration experience,overseeing numerous public works projects. Mr. Collingwood’s resume is provided in the “Resumes”attachment.

Part D. Environmental and Socioeconomic Impacts

PART D. ENVIRONMENTAL AND SOCIOECONOMIC IMPACT

1. Impact Checklist: See attached completed checklists.

2. Impact Narrative:

� Air quality impacts: The project may increase the short-term potential for release of pollutants toambient air from dust associated with the dam removal construction activities, as well as short-termemission releases from construction vehicles at the site. Best construction practices will be employedto reduce the impacts to air quality. This may include watering down of the construction access roadduring especially hot and dry days and reducing idling times of construction vehicles.

� Instream flow impacts: Instream flow will be altered during the dam removal construction phase bybypassing around the structure using sandbags. Work will be done in late summer or early fall to takeadvantage of low flow conditions. Over the long term, instream flow will be restored and benefitaquatic life such as migratory fish and macroinvertebrates. Permits will be required which detail howthese impacts will be mitigated, including MEPA Review.

� Surface water quality impacts: The dam removal project may have temporary adverse impacts tosurface water quality in the form of increased turbidity during the construction phase. Through thepermitting process, measures will be outlined to control turbidity during construction. In the longterm, the dam removal will result in beneficial impacts to surface water quality. The reservoir behindthe dam will be removed and the river restored to a free-flowing condition, thereby reducing watertemperatures in the stretch of the river. Permits will be required which detail how these impacts willbe mitigated, including MEPA Review and State water quality certification.

� Sediment quality impacts: There is a large amount of sediment that has collected upstream of thedam. In a sample analysis results showed that several polycyclic aromatic hydrocarbons (PAH)compounds did exceed the screening criteria levels for MassDEP fresh water (See “SupportingTechnical Documentation” attachment). Excavated sediment will not be reused to construct thestream channel due to an exceedance of the screening criteria levels and will only used in uplandareas. Dam removal will restore sediment flow to a more natural process. Permits will be required,including MEPA Review and a permit from the Army Corps of Engineers for sediment removal.

� Soil quality impacts: The banks of the river will be impacted during construction, causing somepotential short-term soil erosion. Pre-construction activities will include installation of sedimentationcontrols, therefore, soil erosion should be minimal. River bank restoration will include bankstabilization with cobbles and boulders to mimic existing upstream and downstream banks, as well asplanting with native shrub and tree species. Bank stability and habitat will be enhanced through time,leading to improved soil quality. Permits will be required which detail how these impacts will bemitigated, including MEPA Review.

� Groundwater quality impacts: There will be no impact to ground water quality; however, alterationof the groundwater level, due to the release of the impoundment, may be a long-term impact. Permitswill be required which detail how these impacts will be mitigated, including MEPA Review.

� Diversity and abundance of aquatic species: The project may influence the population anddiversity of aquatic species during the construction period. It is believed that restoration of the river toa free-flowing, natural system will improve both the population and diversity of resident aquatic


species. Permits will be required which detail how these impacts will be mitigated, including MEPAReview.

� Diversity and abundance of terrestrial wildlife species: A restored and natural stream systembenefits terrestrial species with a more native assemblage of plants, trees, and shrubs. Short-termdisruption to the area during construction is not anticipated to negatively impact the wildlife. Permitswill be required including MEPA review.

� Diversity of plant communities: Aquatic and terrestrial plant species will be impacted duringconstruction activities. Some riverbank plant species may not survive the construction activities.Some shrub and tree species may be deliberately removed, such as invasive species. The long-termapproach is to restore the riverine and riverbank plant communities in a deliberate way throughplanned restoration. Permits will be required which detail how these impacts will be mitigated,including MEPA Review.

� Impacts on aesthetics: During construction, there will be minimal adverse impacts due to the factthat the dam is in a relatively remote, pristine area and not visible unless accessed through the woods.In the long-term, with the dam removed and the river restored, the area will regain its naturalaesthetics.

� Impacts on public health or safety: Upper Hathaway Dam serves no functional purpose and is adeteriorating structure. Removing the dam eliminates a potential hazard to pedestrians and wildlifethat may encounter it.

� Impacts on recreational activity: The project site provides little recreational opportunities in itscurrent condition. After the dam removal and the restored continuous flow of Hathaway Brook,fishing quality will greatly improve.

� Impacts on education: There will be positive impacts to educational opportunities with this project.Locally, educators may wish to use the site as a component to their environmental curriculum withthe topic of river restoration. More importantly, this restoration project will provide an opportunityfor technology transfer to other communities who are exploring dam removal and river restoration.Through consultation and coordination with MA Riverways Program, this restoration project willconstitute a case study and will be well publicized.

� Impacts on local partnerships and collaborative efforts: The dam removal and stream restorationproject involves many partners, which has been previously outlined in the project narrative. Throughsuch cooperation, the dam removal restoration project outcome will be improved.

� Short-term commercial economic impact of restoration action: The river restoration and damremoval will produce benefits to the local economy by providing temporary employmentopportunities in the engineering and construction trades.

PART E. PROJECT BUDGET

Year 1 has been assumed to be FY2010 (July 1, 2009 through June 30, 2010). Year 2 will then beFY2011 (July 1, 2010 to June 30, 2011) and so on.

Table 1

A total of $500,000 is being requested from the NRD fund to cover the construction costs associated withremoval of the Upper Dam on Hathaway Brook. Funds requested from the NRD program will be requiredfor Year 2 (July 1, 2010 to June 30, 2011) since construction work related to the dam removal is expectedto occur between August and November 2010.

Table 2

Six tasks are identified in the project budget summary table. Tasks A through F total $850,000 and arebroken down as follows:

Task A – Feasibility Study: This task includes $65,000 that the City of Pittsfield has alreadycommitted to the project. AECOM completed a study to confirm that it was feasible to remove the twodams on Hathaway Brook. The feasibility study included a topographic survey, bathymetric survey,sediment probing, physical and chemical sediment characterization, evaluation of wetland and habitatresources areas, hydrologic and hydraulic analysis, and development of conceptual drawings. The workalso included consultation with Massachusetts Historical Commission to confirm that there was nohistorical significance to the dam structures and with the Natural Heritage and Endangered SpeciesProgram to confirm that there would not be any adverse impacts under their jurisdiction. The feasibilitystudy was conducted under the consultation of the MA Riverways Program. The City of Pittsfield is notseeking NRD funds for this work.

Task B – Final Design and Permitting: This task includes $60,000 that the City of Pittsfield hascommitted to the project to prepare final design drawings for the removal of the dams and to conduct thenecessary permitting for the upper dam removal. Final design will consist of preparation of plans andspecifications and could include additional topographic survey around the access road into the dam site.Permitting activities will include a Notice of Intent to the Dalton Conservation Commission, MA DEP401 Water Quality Certification application, US Army Corp of Engineers 404 Wetland Permitapplication, an Expanded Environmental Notification Form to MEPA, and a Chapter 253 Dam SafetyPermit from MA DCR. The City is not seeking NRD Funds for this task.

Task C – Lower Dam Removal Construction: This task includes $140,000 that the City ofPittsfield will commit to removal of the Lower Dam on Hathaway Brook. This work will be conductedunder the same construction contract as the Upper Dam removal. The estimated construction costincludes site work and demolition work plus an escalation to the anticipated midpoint of construction onOctober 1, 2010, and a 10% construction contingency for potential change orders arising duringconstruction as a result of unforeseen conditions. The City is not seeking NRD Funds for this task.

Task D – Upper Dam Removal Construction: This task includes $500,000 that the City ofPittsfield is seeking NRD funds for to cover construction costs to remove the upper dam on HathawayBrook. The estimated construction cost includes demolition of the 157 foot long by 22 foot highreinforced concrete dam, removal and disposal of sediment, excavation and backfill, streambedrestoration work and vegetation planting in upland areas, plus an escalation to the anticipated midpoint of


construction on October 1, 2010, and a 10% construction contingency for potential change orders arisingduring construction as a result of unforeseen conditions.

Task E – Engineering Services During Construction: This task includes approximately $40,000that the City will commit to have AECOM provide engineering services during construction to removethe two dams on Hathaway Brook. The work will include construction administration services such asshop drawing review and responding to contractor requests for information. The work will also includepart-time resident observation services. The City is not seeking NRD Funds for this task.

Task F – Long-Term Monitoring: This task includes approximately $30,000 ($10,000/year) formonitoring efforts before and after dam removal. The monitoring effort includes a program to conductelectrofishing in October or November of the year prior to dam removal (FY 2010) as well as years 1 and2 after removal (FY 2012 and 2013). If sufficient information is obtained during these initial two yearsthen further assessment will not be necessary. This task also includes approximately $15,000($5,000/year) to resurvey longitudinal profiles and cross sections at the project site in FY2012, FY 2013,and FY 2015 to document the stability of the stream channel. The City is not seeking NRD Funds for thistask.

Re: Upper Hathaway Dam Removal

Dear MA SubCouncil of the Housatonic River Natural Resource Trustees:

The mission of the Riverways Program (Riverways) is to promote the restoration and protection of the ecological integrity of the Commonwealth's watersheds: rivers, streams and adjacent lands. Riverways was created in 1987 to encourage and support local river protection and restoration initiatives as a vital complement to state action.

I am writing in support of the City of Pittsfield’s application for funding to remove Upper Hathaway Dam. The City of Pittsfield is seeking to restore stream connectivity and aquatic biological resource habitat within Hathaway Brook by removing Upper Hathaway Dam located in Dalton, Massachusetts within the Housatonic River watershed. Hathaway Brook is a tributary to Sackett Brook, which in turn is a tributary to the Housatonic River. The deteriorating Upper Hathaway Dam serves to impound Hathaway Reservoir and is part of a water supply for the City that is no longer in service.

Removing Upper Hathaway Dam will restore geomorphic processes, water quality, and species that depend on flowing water, such as brook trout and long-nosed suckers. Removing dams from small coldwater streams such as Hathaway Brook is particularly important as these streams are frequently the last high-quality refugia habitat in the watershed. Furthermore, these streams supply clear, cool water to larger streams. This project will complement the removal of Lower Hathaway Dam, which is being undertaken as a compensatory mitigation project for the repair of Ashley Lake Dam (please note that no Housatonic River NRD Funds are being requested for the removal of the Lower Hathaway Dam).

Please do not hesitate to contact me regarding our support of this project.

Sincerely,


CC: Bruce Collingwood, City of Pittsfield

Re: Lower Hathaway Dam Removal

Thank you for the opportunity to review and comment on the Lower Hathaway Dam Removal mitigation plan submitted by AECOM on behalf of the City of Pittsfield.

I support removal of Lower Hathaway Dam as a mitigation project, and hope to see more mitigation projects like this in the future. Dams block the natural flow of water, sediment, nutrients, and organic debris. Impounded water temperatures are higher and dissolved oxygen concentrations are lower than in a free-flowing river. Dams fragment aquatic ecosystems, eliminate aquatic species dependent on flowing water, and block the passage of species that use riparian zones for foraging and migration. Removing Lower Hathaway Dam will restore geomorphic processes, water quality, and species that depend on flowing water, such as brook trout and long-nosed suckers. Removing dams from small coldwater streams is particularly important as these streams are frequently the last high-quality refugia habitat in the watershed. Furthermore, these streams supply clear, cool water to larger streams.

I spoke with Ms Jennifer Doyle-Breen several times during the development of the Lower Hathaway Dam removal mitigation plan regarding the appropriate level and type of data collection and analysis for the dam removal project. I have not been to the site myself, but Tim Purinton, Acting Riverways Director, and my colleague Brian Graber, of American Rivers, have both visited the site and are supportive of the dam removal project. Ms. Doyle-Breen sent me the draft mitigation plan and I have had time to review it.

Upon review of the Lower Hathaway Dam removal mitigation plan, I find that it contains the appropriate elements for dam removal engineering and design, including 1) topographic survey; 2) resource area survey; 3) identification of any species of concern; 4) hydrologic analysis; 5) hydraulic modeling; 6) quantification of sediment volume and sediment quality testing; 7) a longitudinal profile of the project reach, from a natural grade control downstream of the dam to a grade control upstream of the dam; and 8)

designs appropriate to the scale and scope of the project. Hydraulic modeling is most useful when post-removal velocities must be predicted in order to mitigate any potential impact on infrastructure or when upstream or downstream flooding is of concern. With no infrastructure at this dam site, and the run-of-river dam having no influence on downstream water levels, a hydraulic model may not strictly be necessary. However, in this case it supports a conservative approach to engineering and design at this site.

The Lower Hathaway Dam removal construction design proposed by AECOM appears appropriate to the scale and scope of the project. The dam is relatively small, and it is on a very small stream, with no roads, bridges, culverts, buildings, utility lines, or other infrastructure in the vicinity. In this situation, a simple, inexpensive construction design is recommended, without excessive hard bank protection measures, engineered in-stream structures, or imported stream bed material. Typically, small steep streams have plenty of native rock, cobbles, and gravel. These streams are able to rearrange existing material to create natural step-pool or cascade morphology. It is not necessary to construct step-pools, weirs, or other structures. Typically these engineered structures fail over time and require ongoing maintenance.1,2 I am pleased to see that The Lower Hathaway Dam removal design is simple, minimally invasive, and does not include engineered grade control structures. Once the construction is complete, no further maintenance should be necessary.

I compared the proposed longitudinal profile with the profile upstream and downstream of the project site. An incorrectly designed longitudinal profile can lead to erosion via a “knick point” migrating upstream. Erosion in and of itself may not be a problem (often the stream reach downstream of a dam is sediment starved). Nonetheless, the proposed profile should “tie in” with upstream and downstream grade control and upstream and downstream reaches. The revised proposed longitudinal profile submitted by AECOM does tie in with the gradient of the reaches upstream and downstream of the project reach. This will allow a natural rate of sediment transport to be established along the stream channel, without excessive erosion or deposition. It is likely that a small amount of sediment movement will take place as the stream moves towards an equilibrium morphology. The island immediately upstream of the dam, for example, may change its spatial extent.

Even with the proposed longitudinal profile, it is possible that natural grade control in the form of bedrock ledges or outcrops may exist under the sediment trapped by the dam. This situation is common to small streams in the glaciated landscape of western Massachusetts. Should this situation occur during construction, the design engineer should be available to alter the design as needed. No blasting or fish ladders are necessary.
