The conceptual site plans you see here are at the widest resolution in order to present the Big Picture of a particular theme park idea. My design mantra is "The Park is the E-ticket" - meaning the goal is to create a park where the visitor can wander around going on few or none of the composite rides and still feel like the experience has been worth it. Granted, achieving this rare feat is mostly done on the micro level (detail and execution), but establishing good skeletal and circulatory systems, themes and transitions, sightlines - and showing the full build-out potential (no park would open on the scale that I present here) - is, to me, the vital first step.
When the time comes to communicate a more detailed idea of what a park would be like, I begin to "zoom in." To show this, I've chosen a small section of the American Experience - a park on which I collaborated with Comics101 a while back.
The area shown, part of Libertyville, is to have the feel of cities like Boston, Philadelphia, New York around the time of the country's founding. This, of course, has already been conceptualized and executed brilliantly by the likes of Herb Ryman and the designers of the Magic Kingdom's Liberty Square (a great gallery of its construction can be seen here).
The Federal, Dutch, Flemish and Georgian Colonial styles of the facades dictate the roof types of this section, and I used a semi-chaotic massing to give the area a theatrical feel. Even the backstage facing roofline of the show-building is themed in order to maintain proper long-distance sightlines (probably unnecessary due to tree-planted berms around it, but with no budget to worry about, why not...).
