The owners of the Boston Harbor Marina desired to upgrade their facility, located in Budd Inlet in Olympia, Washington. Skillings Connolly provided an overall marina evaluation to prioritize facility deficiencies. It was determined that replacing structurally deficient timber pilings was the highest priority. Working with a structural engineer, nine pilings were identified for immediate replacement. Skillings Connolly prepared the design plans and specification, engineer’s estimate, and construction contract for piling replacement. Our environmental staff also completed an aquatic dive survey to determine potential impacts to aquatic habitat. The dive survey was used to support permit application from the Washington Department of Fish and Wildlife (WDFW), the Army Corps of Engineers (USACE), and the Washington State Department of Ecology (Ecology) Timber pilings will be replaced with 18-inch hollow steel pilings. The Squaxin Tribe was contact early in the design process to solicit comments and feedback o n the proposed project. In addition, the Black Hills Chapter of the Audubon Society was contacted as the entire marina is designated Purple Martin nesting habitat. To ensure that the Audubon Society would offer full support of  the project, our environmental staff worked closely with Audubon to provide additional Purple Martin houses as mitigation for potential impacts associated with piling replacement.
