Lake Wilderness Park Dock Replacement Project
Project Background and Schedule

In 2007, the City completed a master plan for Lake Wilderness Park and Lodge. That master plan identified ten (10) different phases of work that were to be designed and built over a 20-year period. Phase #1 – the “Aquatic Recreation Phase”, included four items:

  1. New dock
  2. Boat rental float

With the recession affecting available funding for park development projects, starting in late 2007, this first phase of development at Lake Wilderness Park was put on hold for several years. The existing dock, built by King County in 1972, began to show signs of deterioration.

In 2011, the City Council authorized staff to perform a “condition survey” of the dock and its support pilings to assess its condition. A firm specializing in dock design was hired through a competitive recruitment process and the survey was completed late that year. The results of the survey showed that the dock and pilings were failing and needed to be replaced in the near future.

In 2012, a preliminary design was developed to replace the existing dock in a similar configuration and add a boat rental float. With the preliminary design complete, staff was ready to begin the long permitting process to construct the new dock.

In 2013, project staff completed a Joint Aquatic Resources Permit Application (JARPA) and filed that with the State of Washington to start the permitting process. The following permits and/or approvals are needed prior to construction:

  • City of Maple Valley – State Environmental Protection Act (SEPA)
  • City of Maple Valley – Shoreline Substantial Development Permit
  • City of Maple Valley – Commercial Building Permit
  • Washington State Department of Wildlife - Hydraulic Project Approval (HPA)
  • Washington State Department of Natural Resources – Aquatic Lands Lease
  • US Army Corps of Engineers – Department of Army Permit
    • Section 10 (navigable water) - Not applicable
    • Section 404 (dredging and/or filling of material) – Not applicable
In late 2014, while project staff was still pursuing final permit approvals, the project was put out to bid. The successful low bidder was Neptune Marine, LLC and the City entered into a contract with them to remove the existing dock and pilings, and construct the new dock and install new steel pilings.

Manufacturing of the new floats will be done in a factory, with on-site work expected to begin in late February or early March. The project is expected to be complete in late March 2015.
