Communication is the bench mark of a successful project.
Thoughts on the way to Truckee...
- A 12-inch diameter pipe conveys 6.3 times as much flow as a 6-inch pipe laid at the same slope;
- Roadside ditch erosion begins at longitudinal slopes (slope parallel to road) as flat as 3%, depending on soil type and vegetative cover;
- Just one fully loaded 53-foot flatbed trailer rolling I-80 westbound at 75 MPH will hold approximately 3.2 miles (16,896 LF) of 3-inch diameter SDR7 high density polyethylene pipe. And at 34,806 pounds (net), there’s plenty of room under the legal load limit (net plus tare) for the truck itself (tare);
- Only 15,000 years ago, what is now Salt Lake City was under 800 feet of water (glacial Lake Bonneville). The lake covered 20,000 square miles (almost as big as West Virginia, or 24% the size of Utah). At that point in time, the earth had reached 99.999997% of its current age. Today, the plainly visible shoreline terraces are fascinating;
- Steel is 3.3 times heavier than cured concrete;
- Owning a water right in Utah does not mean you own the water...it means you own the right to use a specified amount of water each year. And if you don’t use it, you can lose it;
- Most clays are capable of holding more water than bank-run sand and gravel;
- Here’s to Herman Shea, former Professor of Civil Engineering at UMass-Lowell and MIT. Explaining why the parabola was the best choice for vertical curves, he brought a great sense of humor (deadpan delivery) and history to the classroom. Having played an integral role in the design of our nation’s first roadway that approached future interstate standards (Mass. State Route 128), he left us with a much deeper appreciation for the long and winding road, and what people are capable of when they simply apply themselves and work together.
- Speaking of applying oneself, the cartographer responsible for the image at top right lends new meaning to the term “focus”.
