1 This project raises the level of your patio by 2-1/2 to 3-1/2 in. ( 2 depending on the thickness of your decking and whether or not you put spacers under the sleepers). 3  So any door thresholds adjoining the patio must be at least that far above the concrete.
Pacific halibut (Hippoglossus stenolepis) are large flatfish that can be found from the Bering Sea in Alaska to northern California. According to the IPHC, Pacific halibut can reach a maximum length of nine feet and maximum weight of 500 pounds. The oldest recorded age is 55 years for both females and males. They reside along the continental shelf and are found in a broad range of depths (from inshore to 450 meters).
Virtually all halibut are right-eyed, meaning both eyes are found on the upper, dark side of the body. Left-eyed halibut are rare; one report suggested a ratio of about 1 in 20,000. In these fish, the eyes and dark pigment are on the left side of the body, and the fish swims with the right (white) side facing down. The dorsal fin is continuous from near the eyes to the base of the tail, and the anal fin extends from just behind the anus to the same point on the other side.
