Film the heritage tree before you film the dirt
On a Central Texas site, what stands on the lot decides the site plan long before the building does.
Tree protection and impervious cover rules here are stricter than most of the state, and they routinely surprise people who have developed elsewhere in Texas. A buyer looking at acreage and imagining a footprint is going to be corrected, and it is cheaper to be corrected by your video than by a review.
So stand at the base of a protected tree and film the part that matters. What a critical root zone does to where pavement can go, how far a drive has to swing around it, and what cover limits do to the footprint a site will hold. Almost nobody in this market has filmed the plain version of that.
Do it on a real tract with a real problem rather than in an office. A heritage tree sitting in the middle of the only sensible truck route teaches more in two minutes than a diagram does in a page, and the buyer who watches it turns up to the next call with better questions.
Cover is the number that quietly decides the deal, and nobody films it either. Walk the drainage, the existing paving and the part of the tract that will never carry a building, so a buyer can see how much of his acreage is already spoken for before he prices it.
