i <br /> I PURPOSE AND APPROACH <br /> 'Itw purpose of this study is three fold: (1) to determine the preunce and extent <br /> of wetlands on the subjen property, (2)assess the potential project impacts on any <br /> weUands,and (3) recommend mitigating measures to avoid,reduce or rnmpensate <br /> adverse impacts. <br /> 7Le approach to accomplish the related project planning needs involves tour <br /> interrelated steps: (1)wetland determination, (2) agency coordination, (3) impact <br /> assessmen4 and (4) mitigating measures. 7tie speciFic approach to implementing <br /> thae steps are Qescribed as follows. <br /> Wcllend Dererminetfon <br /> The methodology used for wetland determination is based primnrily on the <br /> dominance of hydrophytic vegetation (plant species adapted to gro��ring in and are <br /> tolerant ot saturated soil conditions),and to a lesser extene,on soils and hydrology. <br /> i When morc than 50% of the vegetative rnver are hydrophytes, weQands werc <br /> determined ro be present. Vegetation was supplemented with the prcsence of peary <br /> soils and evidence of positive wetland hydrology. Where wetlands were determined <br /> ! ro be preuna, upland plant indicators and topographic changes were used to <br /> determine their extent. Blue and white striped Flagging waz used to delineate the <br /> wetland boundary. Kegel and Associates,Inc. rnnducted a detailed land survey of <br /> � the 6eld delineated wetlands and prepared a map. <br /> Wetland and adjacent upland plant rnmmunities are described by dominant, <br /> common, and infrcquendy occuning plam species in ^.ach of the three communiry <br /> layers: overstory,understory and ground layer. In a�dition to habitat descriptions, <br /> general wetland funMional valucs tor storm and tlood water storage, groundwater <br /> recharge, water quality improvement, shoreline proteMion, and wildlife use are <br /> described. <br /> Agency Coordlnetion <br /> A meeting with Ted Muller of the Washington State Depanment of Wildlife regional <br /> stattwas conducted ro review the site mnditions and to discuss potential impacts and <br /> mitigating measures. 'Ihis rnordination allowed issues and mncems to be rerngniud <br /> eady in the project planning phase. Additional rnordination will be likely ro further <br /> develop the preliminary and rnnccptual plans now being presented. <br /> I <br />
