Commercial T-Dock Replacement

Cap Sante Marina, Anacortes WA

 

Project Description

  • What’s being built
    The Port will demolish the existing creosote‑treated timber T‑Dock (built in 1977) and replace it with a modern rectangular pier supported on galvanized steel pipe piles with pre‑cast concrete deck panels, updated bullrails, and integrated stormwater collection via a trench drain to the sanitary system.
  • Size & configuration (noted variance in sources)
    Scope documents and permits describe replacing ~7,175 sq ft of existing dock with a ~12,575 sq ft rectangular dock; other Port communications reference a ~14,250 sq ft concept from early design and funding narratives. The final constructed area will follow permitted drawings.
  • Utilities & code upgrades
    The replacement includes new electrical, water, lighting, and fire suppression systems, and seismic code–compliant abutment/bulkhead work (sheet pile + concrete backwall).
  • Environmental/habitat actions
    Mitigation removes ~115 creosote piles, 29 ACZA fender piles, and riprap armoring, plus submerged timber debris, and installs large woody debris (LWD) habitat structures in the marina basin (on‑site, ahead of construction).

 

Benefits/Goals

  • Sustain critical working waterfront operations
    T‑Dock supports ~80% of seafood landings in Anacortes, commercial and Tribal fisheries, emergency response, and maritime trades—estimated ~$14M in annual economic activity. The replacement safeguards these functions for the long term.
  • Capacity, safety, and efficiency
    The new rectangular layout expands usable work area, increases structural capacity, and eliminates the unsafe bottleneck at the narrow vehicle entrance to the current T‑Dock—improving truck and equipment access for loading/unloading.
  • Regulatory and resiliency compliance
    Upgrades address seismic requirements and modern stormwater management, reducing environmental risk and improving resilience.
  • Environmental improvements
    On‑site LWD installation and removal of creosote‑treated materials enhance nearshore habitat and reduce contaminant sources in Fidalgo Bay; this approach also costs less than off‑site conservation credits while keeping benefits local.
  • Strategic alignment & funding leverage
    The project secured $7.4M via the USDOT Port Infrastructure Development Program and additional state capital funds (~$1M cited for T‑Dock components), aligning with Port and state objectives for modern, low‑impact maritime infrastructure
