Water Surface Increase Calculation for Wall Openings

I present here the method used by NPS Global Engineers for calculating the post-development water surface increase due to a wall with standardized openings. This method has been accepted for multiple projects (including APN 211-44-273, 216-67-067B, 216-67-067A, 219-40-293J, 211-45-084B, 211-47-031, 211-51-031G, 211-51-020K, 211-51-031K, and 503-51-966M) by Maricopa County Planning and Development.

About Tom Haws and Atlas Land Surveying

Long ago (2014?) Bill Barry affiliated with me as his civil engineering department head. Now that I rarely do any work that I don't give to NPS, any work that Bill needs me to do is done by NPS. The Board of Technical Registration told me I am allowed to be the registrants for as many companies as I want, subject to other rules.

Genesis emphasizes that Noah's flood was not an extinction event

Genesis says:

The Lord said, “I will wipe from the face of the earth the human race I have created—and with them the animals, the birds and the creatures that move along the ground—for I regret that I have made them.” (Genesis 6:7) "I am going to bring floodwaters on the earth to destroy all life under the heavens, every creature that has the breath of life in it. Everything on earth will perish." (Genesis 6:17)

But Genesis says:

Why don't surveys and GIS match?

You may have wondered why surveyors in the 2020's don't deliver their dwg files on standard GIS  projection coordinates, whether UTM, US State Plane Coordinates, or something else. The short answer is that standard GIS projections usually don't give correct distances to the level of precision that real estate surveys need. I explain more below.

Solving Riprap Problems With Concrete Strips

Well-constructed loose riprap beds with proper elevation, gradation, filter layer, and subgrade preparation are a good solution to erosion. But riprap beds have some problems. Because they are uneven both on top and bottom, they obstruct debris and water and they dry or drain slowly.

Be a CEO at NPS Global Engineers

Dear top prospective colleagues,

We hope for you to be an NPS CEO some day. 

Though the unusual reason NPS has for existing makes growth for profit meaningless, careful growth makes sense because more engineers deserve the NPS experience. One of the safeguards of the NPS experience is our Small Companies identity value. The Small Companies value requires one-team companies, meaning that our companies ideally have 6 to 8 colleagues. So for every team of NPS engineers, there must be a CEO.

I would love to add colleagues to NPS endlessly. I love being an engineer, I love what NPS has become, and I love finding the smartest people in the world. Our customers love working with smart, diligent, and attentive people. Hire, hire, hire! But not without more CEO's.

NPS exists to make great jobs and to do cool stuff. If your idea of a great job doing cool stuff might include being an NPS CEO some day, we may be ready for each other.

My first principle of music composition philosophy

I am the George W. Bush of music composition. I am embarking on it (as he did with painting) in earnest at the age of 55 mostly for my own enjoyment. But here's a first principle of my composition philosophy:

Whole Foods Plant Based Eating

Whole Foods Plant Based Eating
by Kato D. Haws Jr.
July 7, 2020

I began eliminating animal products because of high cholesterol. I removed first
whole milk and eggs. Later all dairy. We ended up learning about various vegan diets,
including the Hallelujah Diet and the McDougall diet. In the end the people most
influential for us are Dr. T. Colin Campbell and Dr. Michael Greger. We rely heavily on
the recipes of Cathy Fisher of True North Health, which use no salt, oil or sugar, and no
animal products. Her recipes also happen to be gluten free, which is important to me, given
my family history of problems with wheat.

If you want to try a whole foods plant-based (WFPB) diet but don't know where
to begin here are a few suggestions.
