SiteAI is Prophetic's AI-powered site planning and yield study tool. Select one parcel — or an entire assemblage of adjacent parcels — and SiteAI generates a professional yield study in minutes, showing you:
How many lots fit on the site, with full lot width and depth compliance
Where roads and entry points go
How environmental constraints like wetlands and flood zones affect developable area
What the full site layout looks like, with lot dimensions visible on the map
It walks you through a step-by-step process:
Define your development type
Adjust site boundaries
Account for topography
Plug in zoning rules from ZoneAI — including minimum lot width and depth
Input your home models
Plan stormwater retention and open space
Set road entry points
The output includes a full visual site plan plus calculated metrics — total lots, density, road area, net developable acreage, and more. Each lot's frontage width, side depth, and area display directly on the map at close zoom, so compliance is verifiable on screen.
SiteAI 3.0 introduced automatic lot width and depth compliance. Minimum dimensions are enforced in every generated plan — pulled from your inputs and validated against ZoneAI data — so the yield count is defensible at the underwriting stage. The engine also mathematically maximizes lot yield within zoning constraints, often surfacing one or two additional lots that manual layouts miss.
The old answer to "how many lots can I yield?" was two to four weeks and a civil engineering bill. SiteAI gives you that answer while you're still on the phone with the landowner.
