8 Wetland report was only partially approved. Mason County(MC) staff agrees that the
septic system is greater than 300'from Wetland B and that it is likely it is greater than 225'
from any wetlands that may be present near the south property line. Mason County has
not determined if there are any wetlands present at the south property line. Any clearing
within 225'or development within 240'must have further studies done. Wetland A is listed
as less than 1,000 square feet but Mason County has not received adequate information
for that determination. It was determined that if the wetland was greater than 1,000 square
feet, it is unlikely it would fall into a Category that would require a 225'buffer. No further
information is required unless development is within 125'of this wetland or clearing within
110'.
