Suite i 06 Everetl, Washington 98208 (425)337-3174 Fax (425) 337•30a5 As per yo�u request this letter describes tiie methodology and recommended mitignaon rneasures discussed on ouj February 2, 1998 site visit. An area of concern was idcntified in thc westarn panhnndle of the property by the Ciry of Everetc during the grading application proceas. This area was clea:ed and approxunately two feet to four fcct of filI was placod bctweea ecoloBy blocks that were defining the property boundary. The fill materia! was placed in a small wetland area aa+d crea[ed drainage problems on ad�acent propeties to the north. It was recommended that an eacavator dig tlu�ough the filt material to the original soil so ch�t the area of concecn might be identified. Five holos, tanging in depth from t1u'ee fcct to six fcet, wece dug approximauly thirty fect apart alang th� panhandle. Non-wedand soils identificd below the fill material were typically a lOYR 3/1 silt loam from the surface (original) to twelva inches below, From twelve to greater than aighteen inches the soils changed to a 2.SY 3/2 silt loam wich no redoximorphic feantres. Wedand soils were typically lOYR 3i2 gravelly silt loam from che surface (original) to ten inches below, From ten inchcs to greater than eighteen inches ehe soits changed to a 5Y 4/1 gravelly sitt loam with slight r�doximorphic featurts. At the end of this investigation it w� detormined that a Categoc�r III wedand, less than SUO square feet in size, existed in the panhandle prior to filliag. The C►ty of Evcrete's Orriinance Number 1838-91 Soction S(A)(7) states chat Category III wetlands less than 500 square feet in size having only one wetland cless, which is not forested, and which is hydrologically isolated are exempt from regulation. 'Ihis wetland appears to be exempt from regulation and no protective measures arc required. To rectify drainage problems and potential conflicts with neighbors, the storm �rainage plan pregar�d by the site engineer will be modif�ed to reflect drainage issues along che westem panhandle. In additiorz, perimeter plencings of native vegetation such as NootkA rose (Rosa nutkana) will be ptaced along tttc northzrn and western side of the panhandle to providc a screen between che subjectproperty snd adjacent properties. The proposed dctendon pond and bioswale will be graas accdcd and planted to meet the desigt� critreria astablished in the C3ty of Everett's Storm and Surface Watcr raquirements (4-10 and 4-12), If you have arey comments or eoncems, please give me a call. � � �� � �� 5cott Brainard - Senior Wetland Ecologist cc/ Ron Downing Frans R, Thuyns �q� 3�
