Goal: This is the second grant in a multiple year process through which GBBC is addressing its privately owned, aging tidegate system. The goal of the second grant is to refine the conceptual open channel design into a “permit-ready” design for subsequent construction phase. This includes completion of a 90% engineered design, application for construction permits, and continuing stakeholder outreach and consultation.
GBBC received the grant from Washington Recreation and Conservation Office (RCO). GBBC is contracting with Whidbey Island Conservation District (WICD) to handle financial and reporting tasks, oversight of technical consultants, and design/permitting tasks.
GBBC has sole responsibility for all decisions regarding expenditure of the grant monies.
Scope of Work:
Stakeholder outreach and consultation
Engineering Design technical analyses to be completed by consultants:
Channel outlet design and verification of tidal conditions (based on coastal geomorphic and H&H data)
Refine hydraulic modeling to further evaluate potential for flooding in marsh
Geotechnical investigation and dike design
Biological issues assessment (not yet funded; will be informed by permit requirements)
Engineering design and drawings, including additional field studies
Permit applications (including pre-application meeting with Island Co)
Develop funding opportunities and apply for construction funding
Start date: 1/19/18
Stakeholder outreach: throughout grant period
Field studies, including water level and salinity baseline monitoring: begin March 2018
Publish RFP for engineering consultants and hire consultants: July 2018
