The regulatory matrix is pretty confusing and I do what I can to hook clients up with good information.
Kittitas County has released a Frequently Asked Questions (FAQ) document to inform citizens as to why and how the county maps wetlands and streams, the location of which can be determined using its online COMPAS tool.
The FAQ also explains why a wetland/stream professional is required to determine whether a mapped location of one or more of these critical areas is accurate.
A copy of the FAQ can also be obtained by jumping over to the Resources page, under “Kittitas County.” I also touch on this subject over on the GG FAQ page
