Debris basins · 3D tool
How full is the basin after each storm?
Five real drone LiDAR surveys of one basin below the Eaton Fire, Oct 2025 to Feb 2026. Scrub through the storms, set your cleanout trigger, and export a status sheet.

Public LiDAR, shown to demonstrate the method. These numbers describe the sample site, not yours, and are not a survey.
A Twinn survey of your site comes with checkpoint accuracy, a report and the surfaces, for review and seal by a licensed PLS/PE where required.
