By granting permission, you are allowing Environmental Services staff to access the stream located on your property. If we can only access the stream via your property, we also request your permission for this access. Environmental Services staff will visit the stream up to 15 times in one year (from April 2024–June 2025) to conduct a watershed assessment, collect water quality samples, and perform fish and avian surveys. You do not need to be at home during the visit.
