The CAO has adopted the Department of Ecology’s Wetland Rating methodology. Reference CAO Section 183 Wetlands are classified into four categories using the Washington State Wetland Rating System for Western Washington (Ecology publication #04-06-025). The Washington State Wetland Rating System categorizes wetlands based on specific attributes such as rarity, sensitivity, and function. The rating system uses a point system designed to differentiate between wetlands based on their sensitively to disturbance, their rarity, our ability to replace them and the functions that they Wetlands 2-54 provide. It is important to recognize that wetlands of all categories have valuable functions in the landscape. The wetland rating system does not recognize illegal modification to wetlands. The Washington State Wetland Rating System for Western Washington is available at: http://www.ecy.wa.gov/biblio/0406025.html.

I - unique or rare wetland type, more sensitive . Score 70 (out of 100 from wetland rating form)

II - Wetlands that are difficult, though not impossible to replace, provide high levels of function.score 51 to 69 points for habitat

III - Wetlands with a moderate level of functions, scores of 30 to 50 points for habitat

IV - Wetlands with lowest levels of functions (scores less than 30 points for habitat

Wetland rating such as 1,2,3,4 from SAO Wetland survey. Category I Wetlands that represent a unique or rare wetland type, or are more sensitive to disturbance than most wetlands, or are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime, or provide a high level of functions, score of 70 points (out of 100) on the wetland rating form. Category 1 wetlands include estuarine, bogs, mature and old-growth forests, coastal lagoons, wetlands that perform many functions very well. Category 1 wetlands may be part of the “priority habitat” as defined by the Washington State Department of Fish and Wildlife (WDFW) http://www.wdfw.wa.gov/hab/phspage.htm, or be identified as a Natural Heritage wetland by the Washington Natural Heritage Program of the Department of Natural Resources (DNR) http://www.dnr.wa.gov/nhp/index.html. Category II Wetlands that are difficult, though not impossible to replace, and provide high levels of some functions. These wetlands occur more commonly than Category I wetlands but still need a relatively high level of protection. Category II wetlands include, but are not limited to , wetlands that perform functions well and score 51 to 69 points for habitat. Category III Wetlands with a moderate level of functions, scores between 30 to 50 points for habitat and generally have been disturbed in some ways, and are often less diverse or more isolated. Category IV Wetlands that have the lowest levels of functions (scores less than 30 points for habitat) and are often heavily disturbed. These are wetlands that we should be able to replace or improve. These wetlands may provide some important function and also need to be protected. See Habitat Point used in wetland rating, Category I = Score >70 Category II = Score 51-69 Category III = Score 30-50 Category IV = Score < 30

2 - Category II = Score 51-69; Wetlands that are difficult, though not impossible to replace, and provide high levels of some functions. These wetlands occur more commonly than Category I wetlands but still need a relatively high level of protection. Category II wetlands include, but are not limited to , wetlands that perform functions well and score 51 to 69 points for habitat.

3 - Category III = Score 30-50; Wetlands with a moderate level of functions, scores between 30 to 50 points for habitat and generally have been disturbed in some ways, and are often less diverse or more isolated.

4 - Category IV = Score < 30; Wetlands that have the lowest levels of functions (scores less than 30 points for habitat) and are often heavily disturbed. These are wetlands that we should be able to replace or improve. These wetlands may provide some important function and also need to be protected.

1 - Category I = Score >70; Wetlands that represent a unique or rare wetland type, or are more sensitive to disturbance than most wetlands, or are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime, or provide a high level of functions, score of 70 points (out of 100) on the wetland rating form. Category 1 wetlands include estuarine, bogs, mature and old-growth forests, coastal lagoons, wetlands that perform many functions very well. Category 1 wetlands may be part of the “priority habitat” as defined by the Washington State Department of Fish and Wildlife (WDFW) http://www.wdfw.wa.gov/hab/phspage.htm, or be identified as a Natural Heritage wetland by the Washington Natural Heritage Program of the Department of Natural Resources (DNR) http://www.dnr.wa.gov/nhp/index.html.
