Grading Season Exceptions
Grading Season Exceptions
The Lake Tahoe Basin grading season runs from May 1 through October 15 as long as conditions are dry. Outside of the grading season, construction sites must be winterized and all soil disturbing activities (excavating, backfilling, etc.) are prohibited unless a Grading Season Exception is issued by TRPA. Exceptions are only approved for projects where an emergency exists and the grading is necessary for the protection of public health and safety, for erosion control purposes, or for the protection of water quality. Grading Season Exceptions are not issued to excavate a new foundation.
The following activities do not require an exception, even outside the grading season:
- Up to 3 cubic yards of soil disturbance (when not part of a larger project) if completed within 48 hours and the site is stabilized to prevent erosion
- Paving, if all grading and base compaction is already complete
1. Gather information about the property. In order to complete the form, you will need the permit number (TRPA, County, or City permit) and either the property address or APN. Photographs are required for review of your GSE request. Required photographs include:
