Runway 01 Safety Area (RSA) Improvement. Southern Vermont Regional Airport is a general aviation and small-scale commercial airport served by a 5,003-ft runway and minimal apron surrounding the terminal buildings, and a localizer separated 470 ft from the north end of the runway.

The Runway Safety Area Improvement Project included the design of a new 50-ft-wide taxiway parallel to the existing 5,003-ft by 100-ft-wide runway to serve as a staging and taxi area, which was previously accomplished solely by the runway. The project included construction of a 600-ft-long RSA at the north end of the runway, which uses an Engineered Material Arresting System (EMAS) to safely arrest overrunning aircraft. This system resembles a runaway truck ramp. In place of a gravel or sand medium, the EMAS uses crushable concrete blocks installed on top of pavement at the end of the runway. This reduces the required length of the RSA by 40%. Due to the grade at this end of the runway, a 55-ft-high two-step mechanically stabilized earth retaining wall was necessary to reduce impacts to a nearby Class III wetland and to maintain a reasonably level surface. Project included relocation of the localizer. Design also included the connection of Taxiway D to the end of the runway. For this project, DuBois & King also provided permitting assistance for stormwater, construction stormwater, and Act 250.

Runway 19 Safety Area Improvement. Construction inspection services for the construction of a 600 ft by 400 ft Runway Safety Area on the end of Runway 19. Professional services include shop drawing review, periodic site visits, subconsultant coordination, review of change orders and RFIs, final inspection, preparation of record drawings, and updates to the Airport Layout Plan.

DuBois & King serves as the Airport Engineer for Norwood Memorial Airport. Over successive, consecutive terms, D&K engineers have assisted the Airport with professional services related to funding assistance, environmental considerations, and design for multiple projects including:

Reconstruction of Taxilane ‘B’. Design and construction services for the reconstruction of a 2,600 ft by 35 ft taxilane project. Services included design and as-built surveys, environmental permitting, taxilane design, and construction inspection and administration. Design elements include pavement design with reclaimed pavement, grading and drainage improvements, edge lighting, signage, pavement markings, and the evaluation of aircraft tie-down separation from taxilane to maximize the number of tie-down spaces.

Reconstruction of Runway 10-28 (approx. 450 ft by 75 ft) and Remark Runway 28 with a Displaced Threshold. Project management, design of bituminous concrete pavement, edge lighting, pavement marking, drainage, site grading, and construction management of a runway reconstruction project. Project included survey and geotechnical investigation, pavement geometry, pavement design, stormwater management, site grading, utility modifications, pavement markings, construction phasing, erosion control measures, quantity take offs, and construction estimates.

Other projects include land acquisition in the runway approach and runway protection zone (RPZ), and purchase of snow removal equipment.

Project included completion of an Environmental Assessment (EA) under the National Environmental Policy Act (NEPA), and Vermont Act 250 compliance and documentation for construction of expanded runway, tie-down apron, fuel farm, and FBO facility. Followed statutory and Federal Aviation Administration (FAA) regulatory structure for preparation of appropriate environmental impact analysis documents, from data collection through public scoping and agency consultation, to document drafting and public hearings.

Updates to original Airport Master Plan included developing a comprehensive plan to guide future development of the airport. Planning efforts supplemented and revised information from current Airport Master Plan to bring existing information in line with current conditions. Collection of data included coordinating, attending, and conducting scoping meetings with the Town of Fair Haven, VTrans, and Federal Aviation Administration (FAA). Master Plan Technical Report included: reviewing current Airport Master Plan and revising socio/economic growth patterns to reflect current patterns, forecasting methodology, establishing an Airport Reference Code, defining sets of screening criteria in accordance with FAA, reviewing development alternatives, updating construction cost estimates for Master Plan alternatives, analyzing preliminary development alternatives, and utilizing noise contours to assess noise impacts to surrounding community. Air quality analysis and environmental impacts from sanitary and industrial waste as outlined in the existing Master Plan were reviewed for completeness.
