Timber <br />The remaining Piers J through Q consist of timber floating docks and fingers. There are <br />approximately 48,700 square feet of timber floating docks and generally are in poor condition. Piers <br />P and Q were considered unsafe and are currently closed to the public. While the remaining timber <br />docks are in use, they do not appear to be salvageable. <br />2.2 Dock Guide Piles <br />Each type of floating dock has a unique type of guide pile: steel, concrete, and timber. <br />Steel <br />There are four steel guide piles at the old refueling dock and they appear to be in good condition <br />without any noticeable corrosion or section loss. These piles are expected to be fairly <br />straightforward to remove in one piece, and are valuable as scrap metal. <br />Concrete <br />When Piers A through H were renovated in 1990, the existing timber piles were removed and <br />replaced with 15-inch octagonal precast and pre-stressed concrete piles that were 45 feet long. <br />The access piers on the land side were also replaced with new concrete piers and piles which were <br />30 feet long. There are a total of 189 concrete guide piles and 16 concrete access pier piles. These <br />may be salvageable if it is possible to remove them without damage. <br />Timber <br />At the remaining Piers J through Q, instead of individual guide piles, four timber piles were bundled <br />together to form a single structure (dolphin) to secure the docks. Many piles appear to have been <br />repaired in the past, such as fiberglass jackets to prevent further section loss, or new steel or <br />concrete caps to restore the upper portion of the timber piles. Per the as-built drawings, the <br />dolphins are 16 inches in diameter and 50 feet long, and comprised of 112 individual piles. <br />At the access piers, there are a total of twelve 16-inch diameter timber piles. Total length of the <br />piles is unknown and the timber piles are not considered salvageable. <br />There are five additional restroom/storage structures supported on timber piles over the marina or <br />embankment. Each restroom is supported by eight timber piles that are 16 inches in diameter and <br />having an unknown length. The Harbor Master’s office building is supported by 20 vertical timber <br />piles that are 12 inches in diameter and approximately 55 feet long. There are also eight battered <br />timber piles that are 12 inches in diameter and 60 feet long. Additionally, there is also a ramp <br />leading to the Harbormaster’s office which is supported by eight straight timber piles, 12 inches in <br />diameter with unknown lengths. <br />North of Pier A is what remains of the Blue Dolphin Restaurant. The previous building owner closed <br />his business and left the building to rot and all that remains are the piles and pile-supported <br />foundation. Due to the highly deteriorated state, it was not safe to inspect or quantify the piles. <br />The timber piles are not anticipated to be salvageable and due to deterioration it may be difficult to <br />completely remove the piles without damage. <br />20
