Marina Condition Assessment
PND Engineers, Inc. has been contracted to execute an underwater review of Fidalgo Marina in 2021. The diving portion of this assessment will occur May 27-28 and the assessment documentation and recommendations are expected in late August.
Underwater Condition Assessment
Fee Estimate for Condition Assessment
6/22/21 – The dives executed on 5/27 & 5/28 found our marina docks and the concrete pile to be in generally good condition. However, the dives uncovered a reduced cross-section in both H-piles and pile batters. The H-piles are the vertical breakwater piles that capture the concrete panels. The H-piles new were .600″ and currently they range from .303″ to .600″. The pile batters are the sloped 12-3/4″ round pile that supports the breakwater during wave and wind loading. The pile batters new were .375″ and today range from .000 to .375″. Said differently there are 16 piles that have holes in them some up to 1′. Additional engineering is currently underway to determine how to repair/replace these piles.

7/1/21 – Echelon Engineering Draft Report
The link above is a draft report from the Echelon dive team. This report covers 25% of the docks and docks concrete piles and 100% of the North and East breakwaters. As discussed in the June 21st board meeting the North breakwater is at the point of failure. Most of the pile batters are missing significant portions of their cross-sections. PND Engineers is developing options, report forthcoming.

PND Proposal for Emergency Repairs
The link above is the $38,300 proposal to engineer emergency repairs on one or both of our marina breakwaters.
8/18/2021 – PND Emergency Repair and General Repair Proposal
8/23/2021 – The Board voted unanimously to spend up to $350,000 to repair severely damaged pile batters on the North and East breakwaters. This repair will be carried out using CarboSleeve inside the existing piles. CarboSleeve is a carbon fiber sock that is expanded and filled with epoxy grout creating a new pile within the existing steel pile.
2/1/2022 – The CarboSleeve repair failed due to poor wetting out of the carbon fiber sock. The CarboShield Inc. epoxy would not flow as designed at temperatures below 50deg. The product was tested again by the reserve committee, PND, and Culbertson Marine at the Culbertson yard two months later. The test included new [thinner] epoxy formula from CarboShield and a 12″ PVC pile. Once complete we cut open the PVC pile to expose the sleeve. Once again the sleeve was not wetted out so there was limited bond strength. After this test we abandoned CarboSleeve.
9/12/2022 – Breakwater repair update. The Reserve Committee completed its due diligence working with PND and Global Diving and Salvage to arrive at a new repair solution. Emergency permitting is in process and we expect Corps approval any day.

Puget Sound Partnership Debits and associated Credits
Almost every in-water project now requires the purchase of offsetting credits from the PSP. The PSP acts as a broker for the funds and allocates them to nearshore projects such as eel grass restoration, creosote pile removal, etc. We had 44 debits from our 20-pile east breakwater repair at the cost of $62K.

At the request of the DNR we executed a roof evaluation in September. Report above.
East Breakwater Inspection
9/16/2024 Breakwater Inspection
Four years after our first reserve study we asked Echelon Engineering to return and dive on the East breakwater. The goal was to determine if there was any additional section losses.
