RE: MASON COUNTY TAX PARCEL NO 12220-50-17003 1
Dear Mr.and Mrs.Root:
Thank you for contacting me regarding the above referenced parcel as identified in a report dated
October 11,2007 titled Wetland Analysis Report for a 2 Acre Property on East North Bay Road,Allyn
Mason County, Washington and prepared by Wiltermood Associates,Inc. Per your request,a site visit
was conducted in early July,2016 to compare current site conditions with those present at the time of
the report.
Since the time of the report,a single family residence(SFR)has replaced an existing trailer in the
northerly portion of the original parcel. This area was not observed during my site visit. My visit
focused on land southerly of the existing SFR in the vicinity of a recently installed approach and
drainage features. As I understand it,the purpose of this visit is to help determine if changes in the
wetland as a result of this recent installation appear to have occurred,outside of the direct impacts.
The original report prepared by Wiltermood and Associates was comprehensive in describing
conditions identified in 2007 and mapped the extent of wetland area. I found no change to plant
communities,hydrology or soils in the area between and surrounding the newly installed features
across the site to the shoreline. At the time of the report,one perineal non fish bearing stream was
identified that appears to match the location you directed the water course that was more recently
shown to intersect this original channel(N.L.Olson&Associates,Inc).
The palustrine wetland was described as a forested sloped wetland dominated by Red Alder,Western
Red Cedar with an understory of Salmonberry and Red Twig Dogwood(Wiltermood Associates,
Inc.),all present under today's conditions and thriving. Soils were saturated near the surface,and
hydric soils are present. An exact comparison of hydrology cannot be made due to work being
performed at different times of the year and changes in climate,however,the presence of hydrology
during the growing season which I was able to document is a good indicator that no dewatering of the
wetland appears to have occurred.

The wetland rating system was revised since 2007 and implemented last year. I did not re-rate the
wetland under the new system. The wetland category determines buffers and ratios for replacement in
the case where wetland will be filled and replaced as mitigation. These items do not appear to be
applicable and the new rating system is time consuming to complete,so I have not provided an update
to that information. I reviewed the rating provided in the report and find improvements to vegetation
cover noted but no changes to responses that would result in a different category determination under
the system applied. At the time the wetland met the criteria for a category III wetland which is
considered a lower category than a category I or 11 wetland and higher than a category IV wetland.
If you require additional information,please feel free to contact me.
Please be aware that all work performed by a private consultant is subject to review and approval by
the agencies regulating wetlands and natural waters.
