Dear Ms. Surber:
This letter is a brief description of my site review and a confirmalion of the information
provided to you in our meeting of June 24,1997. The third party review of the wetland
delineation was requested the City of Port Townsend with the concurrence of the property
owner, Mr. Arthur Karno.
I met Dixie Llewellin of Olympic Wetland Resources on the site and reviewed the wetland
delineation, on June 24,1997. The delineation appeared to be fine except for the western end
of the delineated line. The western end is dominated by plants most frequently found in non-
wetland areas, but there was evidence of a high seasonal water table and some wetland
adapted plants. The wetland boundary upp.urs to be expanding, which may be a normal
fluctuation in the wetland boundary based on annual fluctuations inprecipitation, or as a
result of increased impervious surfaces or other human-caused processes. The past two
years have had higher than average precipitation, which follows several years ofbelow-
average precipitation in the early 1990's
My interpretation of the wetland bouhdary is slightly different than the one flagged by Dixie
Llewellin, although not significantly so. I placed four wetland boundary markers starting at
the.western edge of the site and ending at Olympic Wetland Resources flag SP-8. The Swan
Resources flags are 2 to 6 feet south of the OWR flags. My markers are pink and black
striped flagging marked as follows:
Swan Resources 6124 #l
SwanResources 6124#2
sP.6124#3
SR 6/24 #4 (atOlympic Wetland Resources flag SP-8)
As we discussed in our meeting, this is a high quality Class II wetland with several plant
communities and a high score on the Significant Habitat Value section of the Department of
Ecology Wetland Rating System. I recommend that the wetland have at least a 100-foot wide
buffer of native vegetation to protect the water quality and wildlife habitat
