Subdivision Review
Subdivision reviews are governed by Wyoming Statutes §§ 18-5-301 to 315 and Water Quality Rules, Chapter 23.
DEQ reviews all subdivisions that meet the following criteria:
- Subdivisions with more than 5 parcels
- Subdivisions with parcels that are larger than 35 acres
- Subdivisions with unique site conditions or other criteria where the county requests DEQ’s review
The Subdivision Review Process flow chart explains the steps involved in a DEQ review.
Chapter 23, Appendices A, B, and C require analyses for nitrate loading, minimum isolation distances, and impacts on public drinking water supply wells.
Subdivisions reviewed pursuant to §18-5-306(c)for a delegated county are exempted from DEQ review. The table below lists how many subdivision parcels each county will review and additional criteria that may apply. Please verify these criteria with the county before proceeding.
