Met with two representatives from the city, and one from the Parks Dept., last Thursday on the sundial project. They were all very nice, very supportive. Most of the hoops I need to jump through now are reasonable ones: submit a letter of intent; give them a diagram to make sure I'm not digging up electrical lines, sprinkler pipes, etc.; and submit a list of all materials I will need. I'm awaiting a .pdf of the park itself so I can plop the diagram below on top of it, align it, and send it back to them.
I got the layout from a wonderful site in Denmark: http://www.jgiesen.de/hsd/hsd300.html. Just put in your own longitude and latitude, print the result on graph paper, and you got yourself a blueprint. I love the fact that it's simply two flowing lines: an ellipse and a figure eight. The final product will be about 18 feet by 9 feet. 12 markers along the upper half of the ellipse. A 2 x 6 ft. slab for the figure eight.
Anyone wanna throw me a fancy-pants name a little more colorful than "the sundial project" I'd be delighted to hear it.
