Hi Pat –
Dave is our official course designer, but we welcome anyone to submit ideas. There are safety standards we follow for speed, buffer zones, layout/setup, etc that must be followed. Lots of “what if?” goes into the creation and review of designs before we call them done.
I attended a conference in February where Roger Johnson went thru his presentation on course design… outstanding experience. Here’s his latest handbook:

The template we use for Marina… each square = 20 feet.
