Kittery, ME

As part of the Northeast Naval Housing Privatization Project, the Navy selected a consortium led by GMH Military Housing, LLC, and its partner, The Benham Companies, to design, build, operate, and maintain new military housing at eight northeast naval bases. Nobis Engineering, Inc. (Nobis) was selected by the Benham Companies to design new naval housing and infrastructure as part of the housing privatization project at the Brunswick Naval Air Station (BNAS) in Brunswick, Maine.

Conceptual Design

Nobis developed conceptual site plans for three of the naval housing neighborhoods located at BNAS. The three sites included Midway Terrace and Mariner Landing located in Brunswick, Maine and Patriot Common located in Topsham, Maine.

Nobis prepared the concept plans based on site information provided by the Navy and gathered during site visits. Nobis performed wetlands delineation in accordance with the 1987 Army Corps of Engineers Wetland Delineation Manual and the criteria of field indicators for identifying hydric soils in New England, Version 2, dated July 1998. Nobis coordinated with a local surveyor to locate the wetland boundaries in the field and to provide site features and topography on the proposed building sites.

The proposed housing included approximately 214 homes made up of fourplexes, triplexes, duplexes, and single-family homes, two community centers, playgrounds, walking/ski trails, and recreation fields.

Final Design

Nobis provided final design for all three sites including demolition plans, proposed site plans, grading plans, utility plans, and details. Utility design included sanitary sewer, potable water, and drainage systems for the housing facilities. Of significant importance was the design of the storm water systems on-site as the Mariner Landing site was bound by Maine DEP protected waters and the Topsham site was underlain by ledge and impervious clay materials. As a result, a series of storm water best management practices were utilized in the design to account for water quality and quantity. The storm water system design included approximately 6,700 linear feet of new piping, 5 detention ponds, and 4 water quality units. Additional methods utilized in the design of the system included grass lined drainage swales and infiltration trenches to provide treatment to storm water prior to discharge to adjacent water bodies and wetland areas.

Permitting

As part of the permitting process, Nobis prepared a Natural Resource Protection Act Permit-By-Rule as the proposed development was within 100-feet of freshwater wetlands with no impacts within 25-feet of the wetland areas. A Site Location of Development Act Evaluation was prepared including storm water modeling, soils information, groundwater evaluation, and archaeological survey information. Nobis also prepared an EPA General Permit for Construction Activity, which included the preparation of a Storm Water Pollution Prevention Plan for all three sites. Nobis also prepared technical construction specifications for the project.
