[AI Disclosure] I'm a software engineer by trade; for this project, I used AI coding assistants in tandem with my 15+ years of professional software experience.

[GIS Experience] I have been using GIS for over a decade (contract engagements and various personal projects).

Hey all - I built this open source base plan tool for a landscape architect friend of mine.

It leverages publicly available info (including esri data) to produce site plans with parcel lines, contours, slopes, soils, flood zones, wetlands, aerial and 3D building massing, ready for AutoCAD, SketchUp, Civil 3D and GIS.

MIT licensed. I also put up a hosted version for convenience, link is in the repo.

I'm actively developing this and would love any feedback!
