HDD= horizontal Directional drill.
Thanks, I was wondering as well.HDD= horizontal Directional drill.
It's amazing how long that stuff can last.I hauled off 8 or more pickup loads of carpet when I moved here. Some of it was rolled out in the yard, two layers thick. There was an old single wide trailer that had 4 layers of carpet in it. I still find pieces of old shag 18 years later.
That's interesting.Some cities and towns have areas that wee buried by disasters over the years. I know Galveston Texas has areas that were buried by the Great Hurricane. Here is something interesting about Seattle.
>>>Beneath Seattle lies the Seattle Underground, a network of underground passageways, basements, and former streets located in the Pioneer Square neighborhood. This subterranean system was once the original ground level of Seattle, built on filled-in tidelands that were prone to flooding and vulnerable to fire. After the Great Seattle Fire of June 6, 1889, which destroyed 25 city blocks and prompted a major rebuilding effort, city planners decided to regrade the area by raising the streets one to two stories higher—up to 30 feet in some places—to combat flooding and improve sanitation. As a result, the original street level became inaccessible, and shop entrances were left 12 to 22 feet below the new ground level, requiring ladders for access.
The underground space was used for storage and later became a haven for illicit activities, including speakeasies and opium dens, before being condemned in 1907 due to fears of the bubonic plague. It remained largely forgotten until the 1960s, when preservationist Bill Speidel revived interest by launching the first guided Underground Tour in 1965, helping to save Pioneer Square as a historic district. Today, the Seattle Underground is a popular tourist attraction, offering guided tours through its damp, dimly lit tunnels, where visitors can see remnants of 19th-century buildings, vault lights, and historical artifacts. The area is also known for its eerie atmosphere and stories of Seattle’s sordid past.
