TSA Project Portfolio
Master Plan Update and Permitting
TSA provided environmental expertise during the development and screening of alternatives, and prepared environmental evaluations for the 1997 Master Plan Update, which were used verbatim to prepare the Environmental Impact Statement. We also coordinated with regulatory agencies throughout the process, creating a Federal Aviation Administration prototype for integrating airport planning, environmental documentation and permitting into a simultaneous process. TSA is currently working on the 2009 Master Plan Update for the Airport.
The firm has provided various consulting services to Manchester Airport since 1991. We have been monitoring contracts for and the construction of the $300 million fast track design-build airport improvement project for compliance with permit conditions and other environmental regulations. We work closely with the airport staff, airside and landside tenants, and the various regulatory agencies to address a wide range of environmental and planning issues. TSA has completed studies involving groundwater quality, vegetation management, wetland delineation, and hazardous materials/property acquisition, wildlife management, and Part 106 historical/ archaeological compliance. Furthermore, we have evaluated the status of the airport’s underground storage tanks for compliance with state and federal regulations. Services included:
Harrisburg International Airport
TSA has served as Environmental Service Manager at Harrisburg International Airport. TSA completed NEPA required Master Plan EA Re-evaluations in cooperation with the Easter Region of the FAA on the Runway Taxiway Extension and Localizer Relocation and a Re-evaluation of the Categorical Exclusion for the Amtrak Park and Ride Facility in cooperation with PENN DOT.
TSA also performed general environmental services for demolition and construction activities at Harrisburg International Airport. The site is a delisted Superfund Site. TSA support services included soil testing, removal and remediation, building demolition hazardous materials audits, erosion and sedimentation support, on-site sampling analysis, preparation and review of demolition and construction specifications, ground water testing and remediation, hazardous materials emergency response, and environmental support to the on-site contractor as well as other contractors supporting the Airport. Work for the Airport included an EA for the demolition of an on-site power plant, a re-evaluation of the Master Plan EA for an on-site water tower and pump station, and two underground storage tank fuel farm closures.
Norwood Memorial Airport
TSA prepared an airport-wide vegetation management plan and quickly obtained all permits for both an emergency tree clearing project and the airport-wide tree clearing. TSA delineated and assessed all wetlands and identified other sensitive resources on the 400+ acre airport property, 75 percent of which are classified as wetlands, and all of which lie within a state-designated “area of critical environmental concern.” The long-term management plan is a state-of-the-art, natural resource-based management plan for removing vegetative obstructions and maintaining the airport obstruction-free in perpetuity. The aviation and environmental communities praised the plan as innovative and responsive to their concerns.
Since 1988, TSA has worked at Hanscom Field performing wetland delineation, functional assessment, and mitigation design; wildlife; vegetation management; water quality; and permitting. Representative projects include evaluation of the development potential of land parcels, permitting for runway improvements, vegetation management planning and associated permitting, and a Generic Environmental Impact Report (GEIR) for various projects. As part of the contract, TSA attended public hearings, coordinated with regulatory agencies, and responding to comments on the GEIR.
Rochester, New Hampshire
TSA was retained to prepare an environmental analyses for an Environmental Assessment for proposed airport improvement projects including a runway extension, construction of a parallel taxiway, and construction of additional hangars. TSA scientists and planners worked closely with the NH Division of Aeronautics and the City of Rochester to identify potential environmental constraints and evaluate possible project alternatives and environmental impacts. The presence of extensive on-airport wetlands required coordination with state and federal regulatory agencies to identify potential mitigation sites. TSA personnel delineated site wetlands and evaluated their functions and values, and worked with the state to develop a mitigation package that included on-site water quality BMP design and an off-Airport 80+ acre wetland/upland preservation site. TSA is currently working on the wetland and water quality portions of the Airport's Master Plan Update.
Sanford Regional Airport
Master Plan Update, West Side Developments
TSA provided environmental services for the proposed development in the western portion of Sanford Regional Airport. Work included obtaining information on critical habitat and threatened and endangered species through correspondence with the US Fish and Wildlife Service the Maine Department of Inland Fisheries and Wildlife, and the Maine Department of Conservation, Natural Areas Program. A field review was also conducted to determine the presence of critical habitat or rare species.
Wetland resources within the study area were delineated and a functional assessment was conducted. The delineated wetland boundaries were located in the field using GPS. As an additional part of the wetland delineation, drainage swales within the study area were reviewed to determine if they should be classified as streams or ditches. TSA prepared a report that summarized the results of the wetland delineation and functional assessment. The report also included information on endangered species, wetland permitting, and NEPA documentation for the proposed development.
Rutland State Airport
Since 1995, TSA has been providing Rutland State Airport with natural resource management and planning services for proposed improvements. TSA delineated wetlands and evaluated the environmental constraints associated with a proposed runway improvement/runway safety construction project. Under separate contracts, TSA delineated wetlands and determined their functional roles pursuant to the design of a non-directional beacon site and a Doppler VOR navigational aid site.
TSA also evaluated potential wetland, water quality, water supply, air quality, wildlife, endangered species, and floodplain impacts for the recently completed Master Plan Update. Through TSA’s efforts, the Airport acquired a Vermont Act 250 Permit for its runway improvements and a Vermont Conditional Use Permit for wetland impacts associated with an extension of the Airport’s ODAL system.
In 2001, TSA was retained to prepare portions of an Environmental Assessment for proposed Master Plan Airport Improvement Projects. For this project, TSA delineated additional wetland areas and evaluated potential impacts to the area water resources. The information compiled for the EA was used to acquire a federal Section 404 Wetland Permit and a state Conditional Use Permit.
TSA re-delineated wetlands in 2009 for the Final Design and Permitting Phase of a road relocation and runway safety area project. The delineation also involved coordinating with the U.S. Army Corps Engineers and the Vermont Agency of Natural Resources to determine the jurisdiction and classification of several wetlands.
Hartness State Airport
TSA is currently working on an airport hazard beacon replacement project at Hartness State Airport. The project involves replacing the existing beacons with LED beacons, replacing the existing towers, and adding solar panels. TSA conducted field reviews of the tower sites, completed a NEPA Environmental Assessment, prepared the wetland and Act 250 permit applications, and coordinated extensively with the Vermont Agency of Transportation, the Vermont Agency of Natural Resources, and the Act 250 District Commission.
TSA delineated wetland resources and performed a functional assessment to identify potential environmental constraints to proposed airport improvement projects. TSA also mapped the wetland resource boundaries using GPS and prepared natural resource base plans. Additional tasks included evaluating potential impacts to water resources and the preparation of a NEPA Environmental Assessment.

TSA provided expertise in surface water quality sampling, NPDES construction compliance, pollutant loading analysis, and wetlands for the Laconia Municipal Airport Runway Rehabilitation/New Taxiway Project. The project involved the relocation of a stream to accommodate the runway extension area. TSA’s scientists reviewed background data, conducted weekly field visits, performed stormwater sampling, collected macroinvertebrate samples, and coordinated with various regulatory agencies to develop a stormwater sampling plan and identify sampling locations.
TSA also conducts quarterly visual monitoring and yearly tenant inspections as part of the requirements for the NPDES MSGP.
Concord Municipal Airport
Concord, New Hampshire
TSA provided environmental support for the preparation of an Environmental Assessment (EA) that evaluated several proposed improvement projects at the airport, including a new parallel taxiway, tie-down apron expansion, reconstruction of an existing taxiway, itinerant apron expansion, and new hangar construction.
Since a large portion of the airport is designated as conservation zone for the federally-endangered Karner Blue butterfly (Lycaedes melissa samuelis), extensive coordination with the US Fish and Wildlife Service and the New Hampshire Fish and Game Department was required. The Smart Associates conducted field surveys for wild lupine (Lupinus perennis) and several other nectar and rare plant species, Karner blue butterfly eggs, and four state-listed threatened and endangered bird species. The Smart Associates also hired a subconsultant to conduct field surveys for the state-listed endangered Eastern hognose snake (Heterodon platirhinos) and the state-listed threatened black racer snake (Coluber constrictor).
The Smart Associates assisted with the preparation of the EA and prepared the water quality, wetland, shoreland, farmland, wildlife and plants, floodplains, hazardous materials, secondary/cumulative impacts, and socioeconomic sections. As part of the EA process, various project alternatives were developed and impacts were evaluated. The required environmental approvals and permits for each proposed improvement project were also identified. Representatives from The Smart Associates attended two public information meetings and two NH Department of Transportation Natural Resource Agency coordination meetings. Various agency coordination meetings were also held with the US Fish and Wildlife Service, the NH Fish and Game Department, the NH Natural Heritage Bureau, and the NH Department of Environmental Services.
As part of this project, The Smart Associates updated the airport’s Stormwater Pollution Prevention Plan to bring it into compliance with the National Pollutant Discharge Elimination System (NPDES) 2008 Multi-Sector General Permit (MSGP). The Smart Associates also prepared a Spill Prevention, Control, and Countermeasure (SPCC) Plan for the facilities located on Airport property.
Mount Washington Regional Airport
Whitefield, New Hampshire
TSA is currently providing environmental support for the preparation of a NEPA Environmental Assessment for several airport improvements projects. As part of the Environmental Assessment, The Smart Associates delineated wetlands within the project areas and completed a wetland function and value assessment. The Smart Associates is also preparing the wetland, water quality, and wildlife sections of the EA and identifying potential mitigation opportunities.
Route 3 North Improvements
TSA provided environmental compliance and permitting services for this large construction project that involved seven municipalities. Construction occurred through an expedited, fast-paced, and cost-effective design-build process. Within an aggressive schedule of 42 months, 47 bridges, 10 interchanges, rest areas, park and ride facilities, and extensive wetland mitigation sites were designed and constructed along the 21-mile stretch of roadway. MassHighway programmed the project that consisted of adding one additional travel lane and accompanying shoulder in both directions for the entire stretch of highway. One of TSA's responsibilities during the project included obtaining and amending multiple state and federal permits necessary for construction. TSA designed numerous wetland mitigation sites and was responsible for construction oversight of 30+ acres of wetland mitigation, creation, construction, and post-construction monitoring. TSA also provided hazardous materials management, erosion control, and sediment control services throughout the construction process.
TSA provides on-going wetland mitigation monitoring services for the project and is currently conducting a purple loosestrife biocontrol program. The biocontrol program involves releasing Galerucella sp. beetles at several wetland mitigation sites and conducting follow-up vegetation monitoring.
New Hampshire DOT - Hillsborough Bypass
TSA prepared an Environmental Impact Statement for alternative improvements to alleviate the current traffic problems. The effort required of TSA to accomplish this included data collection, field investigation, report preparation, and mapping of the range of resources that would be impacted by highway improvements. Resources inventoried by TSA, and for which impacts were measured, included water resources, hazardous waste, floodplains, wetlands, vegetation, farmlands, wildlife habitat, recreation resources, archeological and historic resources, and aesthetic and visual resources. The process involved interaction with state and federal agencies, including the New Hampshire Wetlands Board, the New Hampshire Division of Historical Resources, the New Hampshire Fish and Game Department, the New Hampshire Natural Heritage Inventory, the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the Natural Resource Conservation Service, the U.S. Fish and Wildlife Service, and the Federal Highway Administration.
TSA is currently involved in the final design of the compensatory wetlands mitigation package for the Route 9/202 Bypass selected alternative. Working with the project team, TSA tracked impact associated with the final highway design and prepared all design plans for the final five mitigation sites including site plans, typical sections, grading and planting plans, and construction specifications. The project includes construction monitoring of the five sites to assure compliance with the ACOE permit, as well as post-construction monitoring.
Salem to Manchester, New Hampshire
TSA is currently providing various environmental services for the final design of the I-93 corridor from Salem to Manchester, New Hampshire. Previously delineated wetlands along the I-93 corridor were field reviewed and wetland maps of the project area were updated. TSA also conducted ecological evaluations of the eight proposed wetland preservation sites that are part of the mitigation plan for the project. Biotic communities, wildlife habitat, water quality features, hydrologic features, geologic features, and passive and active recreational opportunities were evaluated by TSA.
Field reviews of the proposed detention basin sites along the I-93 corridor were conducted by TSA to determine if any constraints were present. Observations relating to wetlands, groundwater, bedrock, and topography were documented for each site. TSA also evaluated culverts and bridges within the I-93 corridor to determine if they could be improved to allow for wildlife and fish passage. Field reviews were conducted to identify areas of existing wildlife habitat and information was collected to determine which species are present along the I-93 corridor. The information was presented in a report that discussed wildlife crossing design requirements, site specific wildlife habitat findings, potential constraints to the maintenance of wildlife corridors, and recommendations regarding each of the 21 potential wildlife crossings evaluated.
TSA is involved with on-going sampling to evaluate water quality impacts to surface waters from road salting operations. In addition, TSA is conducting sampling within several streams to evaluate the efficiency of permanent BMPs..

Ayer - Dunstable Rail Trail Bikepath
TSA provided environmental expertise to a design team during the development of an 11-mile bike path on a portion of the former Boston & Maine Rail line in Central Massachusetts. Work completed included wetland delineation, functional assessment, and permitting. Due to the total acreage of impact, Category II Army Corps of Engineers (ACOE) coordination and a Section 401 Water Quality Certification were also required. The state and federal permitting process required extensive public participation and coordination with four affected communities. The evaluation also involved the assessment of potential impacts to a protected species, the wild lupine (lupinus perennis), and vernal pools. TSA’s evaluations were critical to the selection of an alternative that avoided and/or minimized impacts to the corridor’s natural resources, thus facilitating timely completion of the permitting process. Following the completion of the project, TSA was retained to provide additional environmental expertise for the design and construction of a parking area adjacent to the rail trail to improve public access to the resource.
MBTA North Shore Transit Improvements Project
TSA provided expertise in wetlands, water quality, floodplains, wildlife, and endangered species for the MBTA North Shore Transit Improvements Project Environmental Impact Statement (EIS). The project study corridor parallels the Massachusetts coastline from Revere to Lynn and crosses through the Rumney Salt Marsh, a designated Area of Critical Environmental Concern. TSA’s planners and scientists reviewed background data, conducted field visits, and coordinated with various regulatory agencies to identify existing environmental resources, evaluated the various corridor alternatives, and assessed potential environmental impacts. The results of these studies were documented in the EIS.
TSA also delineated wetlands within the project study corridor and prepared wetland data forms in accordance with the US Army Corps of Engineers 1987 Methodology and the Massachusetts Department of Environmental Protection Delineating Bordering Vegetated Wetlands Manual (1995). The wetland delineation and field reviews were summarized in a Wetland Delineation Report that was submitted to the Army Corps of Engineers.
