• This design project is a collaborative effort between Kitsap County, the Suquamish Tribe, and Landowner to design a voluntary, shoreline restoration project on the Landowner’s private shoreline. The project site is a private parcel southeast of Liberty Bay and nearby Point Bolin within the Port Madison Reservation. The currently armored shoreline extends approximately 100 linear feet with a timber soldier pile wall that is partially creosote treated. The bulkhead is adjacent to a tidal embayment and wetland complex with high nearshore habitat value. The project site has been identified by the West Sound nearshore tool as a Tier 4 restoration opportunity. The County project manager maintains frequent communication with the Landowner, and the Landowner has indicated willingness for this project to proceed and has signed a Temporary Access Easement Agreement. Throughout the design process, the County project manager will facilitate communication between the Landowner, the chosen consultant and the Tribe. • To date a coastal geological memo on bulkhead removal feasibility has been completed. A completed cultural resources survey has indicated no cultural resource findings. The cultural resources survey report recommends that an Inadvertent Discovery Plan be in place and a copy be included with all permits. The property boundary has been surveyed on the eastern property line. (Reports are available upon request). The objectives are to design a restoration project that: 1. Removes the soldier pile bulkhead and restores natural sediment and transport (beach) processes and marine riparian habitat, while providing for homeowner waterfront access and use. 2. Uses ‘soft-shore alternatives’ for shore protection only when necessary and appropriate. Soft shore techniques will follow the Marine Shoreline Design Guidelines (MSDG, 2014). These services include: • Development of a Quality Assurance Project Plan (QAPP) for the collection of all survey and design data that meets the standards and approval of the Northwest Indian Fisheries Commission (NWIFC) and Environmental Protection Agency (EPA). • Feasibility and alternatives analysis. Feasibility will include other necessary investigations and reports such as coastal geotechnical, wind-wave analysis, wetlands and habitat assessments to support a rigorous alternatives analysis. The alternatives analysis will present at minimum three alternatives at the conceptual level including plan view drawings and relative cost estimates and evaluate for the preferred design. The analysis will follow standards set forth in RCO Manual 18 (2023). Basis of Design (BOD) report per RCO Manual 18 (2023) definition and standards for the bulkhead removalshoreline restoration project. One draft BOD report will be submitted for County-team review before the report is finalized. • The preferred design will include design sheets, construction quantities and a reasonable engineer’s opinion of cost (EOC). The preferred design will be at minimum a 60% preliminary design level and permit ready. The design will be stamped by an engineer or engineering geologist. Any plans for wing-wall (bulkhead) design elements will be stamped by a professional engineer. If needed, up to two review cycles for the preferred design will be provided for the County project manager to submit feedback. • Additional surveying for the shoreline area elevations and topography will be completed to enhance the existing licensed survey. This will be done to create an accurate base map for design. • Investigation of outstanding geotechnical considerations needed for developing comprehensive design plans. Potential items to be addressed if deemed necessary might include soils, surface /ground water flow and analysis, borings etc. This geotechnical assessment/report may be included in the BOD’s appendix. • Meetings (in-person and virtual) with the Landowner and County project manager to discuss goals, conceptual designs, alternative design options and preferred option, and to gather feedback. • Technical permitting support with Shore Friendly Kitsap as the lead for permit application submittals.
