(a) Habitat Type. Classify and delineate wetland habitat types based on the U.S. Fish and Wildlife Service Classification of Wetlands and Deepwater Habitats, dated 1979, as now or hereafter amended. Identify the dominant vegetation communities associated with each classified wetland habitat type.

(b) Habitat Diversity. Calculate both the total number of wetland habitat types and the different wetland habitat types identified in subsection (2)(a) of this section for each wetland.

(c) Habitat Size. Calculate the total wetland acreage and acreage of each individual habitat type identified in subsection (2)(a) of this section for each wetland.

(d) Upland Habitat Type. Classify and delineate all lands into one or more of the following land cover categories: developed lands; agriculture; non-native plant species; water; native upland grasses; native forests less than 20 feet in height; native forest greater than 20 feet in height; and mature conifers.

(e) Significant Habitat Features. Identify and delineate the presence of significant habitat features including, but not limited to: estuaries, snags, islands, rare or unique plant communities, mature conifers, Class I wildlife habitat conservation areas, and/or wetlands classified as exhibiting a high functional value (see Table 3) of water availability for migratory waterfowl or other wildlife species.

(f) Species Use. Identify and delineate all known priority habitats for species listed as species of concern or priority species.

(g) Anadromous Fish Use. Identify wetlands contiguous to Type 1 – 3 aquatic habitat conservation areas, or other waters containing anadromous fisheries recognized by local or state public agencies.

(h) Significant Wildlife Movement Corridor. Identify whether one or more of the following areas is located within:

(i) Management and Modification. Identify existing management and alterations of wetlands, and the impact of such actions on the above classifications. Wetland management activities include, but are not limited to: forestry, livestock grazing, agriculture, commercial recreation (e.g., golf courses), residential (e.g., lawns), public lands (e.g., parks, natural areas), and/or land not managed for any other use. Wetland alterations include, but are not limited to: flooding, impounding of water, excavation, filling, grading, draining, or discharge from irrigation or drainage facilities.

(a) Drinking Water. Ability of a wetland to recharge, maintain, and/or enhance surface or ground water resources that yield potable water in sufficient quantities to be economically useful.

(b) Floodflow Desynchronization. Ability of a wetland to retain/detain floodwaters in the upper watershed, reducing the severity of flooding and increasing the time of concentration above that which occurs in adjacent upslope areas.

(c) Ground Water Recharge. This wetland function is significant but not in the context that wetlands act as the major locations of ground water recharge to aquifers. Although some wetlands do provide a significant amount of ground water recharge, the large areas of river alluvium and unconsolidated glacial deposits and, in the Sequim-Dungeness Valley, the irrigation network are much more regionally significant. Rather, ground water recharge is significant due to the fact that wetlands in contact with the aquifer are most susceptible to carrying pollutants to the aquifer. Conversely, if managed properly, such wetlands could assist in the treatment of pollutants already carried in the drinking water aquifer.
