Waters of the US including wetlands are regulated under federal, state, county and city laws and regulations. The lead agency is usually the county or city planning departments within which you live in. Nearly all counties and cites have a minimal size wetland that they will not regulate. Even though certain wetlands may not be regulated under local county or city jurisdiction because oftheir size and mayor may not require buffers, DOES NOT make those areas "non-wetland". Federal and state government agencies regulations require approval and permits before discharging fill into or draining waters ofthe United States including wetlands, even if the county or city is the lead agency for you project. In some cases you may be required to obtain local, state and federal permits before development related to waters of the U.S. and wetlands. There are certain cases where the Federal Court or the Supreme Court has determined that Federal agencies, such as the US Army Corp of Engineers, do not have jurisdiction over certain types of wetlands. For example, based on a U.S. 2001 Supreme Court decision, federal agencies no longer have regulatory oversight for wetlands determined to be isolated that are not associated with interstate commerce use. The Court ruling did not change Washington state laws on wetlands and isolated wetlands are considered waters of the state. Even though a local government or federal agencies may not regulate certain waters of the US including wetlands, does not mean the Washington State government does not. Washington State through the Department of Ecology and Department ofFish and Wildlife regulates all wetlands and waters within the state except for those artificial wetlands intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals detentions facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetland created after July 1 1990, that were unintentionally created as a result of the construction of a road, street, or highway. It is prudent to check with appropriate federal, state and local government agencies to secure approval and the proper permits before proceeding to discharge fill into, or drain waters of the United States including wetlands or their buffers.

These included: a) Review of preliminary site data and, b) On-site investigation to determine the presence of wetlands. A) A review of existing information was conducted to develop background knowledge of physical features, and to identify the potential for wetland occurrence on the subject property. The resource documents available for preliminary review of the site conditions included: USDA Soil Conservation Service (SCS), "Soil Survey of Jefferson County Area Washington", (1990) aerial photography, and the City of Port Townsend and Jefferson County Planning Department's data. b) During the on-site investigation, wetland areas were determined and verified on the basis ofthree parameters: Hydrophytic Vegetation, Hydric Soils, and Wetland Hydrology, as recommended in the Washinf!ton State Identification and Delineation Manual (Washington State Department of Ecology, Ecology Publication #96-944, March 1997). Wetlands categories and wetland vegetation classes were identified and classified using the Washinf!ton State Wetlands Ratinf! System of Western Washinf!ton. Revised. Ecolof!Y Publication # 04-06-025. Thomas Hruby. PhD(Washington State Department of Ecology, August 2004). A positive wetland determination is made when all three parameters are present, or in certain situations determined following the guidelines recommended in wetland determination procedures, or for atypical situations or problem areas. Hydrophvtic Vee:etation Areas where more than 50% of the dominant species present from all strata are hydrophytes (plants adapted to growth and reproduction in saturated soil conditions) are considered to be inside the wetland boundary, unless clear evidence of hydric soils or wetland hydrology cannot be established. A species is considered dominant if it is equal to or greater than 20% areal cover, or exerts a controlling influence on, or defmes the character of a community. Hydrophytic vegetation is determined to be present, when under normal circumstances: More than 50% of the dominant plant species in a plant community have an indicator category of Obligate Wetland (OBL), Facultative Wetland (F ACW), and/or Facultative (F AC) as listed in "National List of Plant Species that Occur in Wetlands: Northwest (Region 9)", (Reed, Porter B., Jr., 1988), and the "1993 Supplement to National List of Plant Species That Occur in Wetlands: Northwest (Region 9)" dated December 1993 that became effective on March 31, 1994. Indicator categories ofFACW+, FACW-, FAC+, are included as FACW status. 'F AC+ species are considered to be wetter (i.e., have a greater estimated probability of occurring in wetlands) than F AC species, while F AC- species are considered to be drier (i.e., have a lesser estimated probability of occurring in wetlands) than FAC species.' Plant indicator status defmitions are presented in TABLE 1 below. This Plant Indicator Status Categories system was developed for the USFWS National Wetlands Inventory by Cowardin et al. (1979). The National Plant List Panel, Reed, Porter B., and Jr. modified it in 1988 and 1993. The Wetland Indicator Category (WIC) used in this report refers to the plants Indicator Svmbol as referred to in the table below. National Indicators reflect the range of estimated probabilities (expressed as a frequency of occurrence) of a species occurring in a wetland versus a non-wetland across the entire distribution ofthe species. ("National List of Plant Species that Occur in Wetlands: Northwest (Region 9)", Reed, Porter B., Jr., 1988), and the 1993 Supplement to List of Plant Species That Occur in Wetlands: Northwest (Region 9) dated December 1993 that became effective Purpose and Approach Continued on March 31, 1994. Percentages expressed as estimated probability. TABLE 1 Indicator Cateaory Indicator Svmbol Definition OBLIGATE WETLAND PLANTS OBL Occur almost always, >99% (estimated probability) in wetlands under natural conditions. <1 % in non wetlands. FACULTATIVE WETLAND PLANTS FACW Usually occur in wetlands, 67-99% and 1-33% in non-wetlands. FACULTATIVE PLANTS FAC Equally likely to occur in wetlands and non-wetlands 34-66%. F ACUL T A TIVE UPLAND PLANTS FACU Usually occur in non wetlands 67-99%, but occasionally found in wetlands 1-33%. OBLIGATE UPLAND Plants UPL Almost always occur in non-wetlands of Northwest Region 9, >99%. <1% in wetlands. Hvdric Soils There have been tremendous scientific changes since 1991 in several ofthe indicators such as the introduction of aquic conditions to cover the requirements for saturation, reduction, and morphological indicators used to defme the modified aquic moisture regime, and mottles and low chroma colors being replaced by redoximorphic features. Because of these changes, we consult the US Department of Agriculture, Natural Resource Conservation Service. 1998. "Field Indicators of Hydric Soils in the United States, Reversion 5.1". G. W. Hurt, Whited, P. M., and Pringle, R. F. (eds.), USDA, NRCS, Ft. Worth, TX for guidance and decision in making fmal hydric soils determinations. Additionally, compliance to changes in Hydric Soils of the United States published in Federal RegisterNol. 59, No. 133/July 13, 1994 and Vol. 60, No. 37/February 24, 1995 addressing Criterion 2 of the Criteria for Hydric Soils definition is being observed. The main purpose for the criteria is to create Hydric Soil Lists. Criteria 1,3, and 4 can serve as both database criteria and as indicators for identification of hydric soils. When Criteria 1,3, and 4 are used to document the presence of a hydric soil, proof that anaerobiosis exists must also be obtained. Criterion 2 serves only to retrieve hydric soils from the database. Also, the wording for Criteria 1 and 2 were changed in 1999 to incorporate recent changes in Soil Taxonomy (Soil Survey Staff, 1999). Field indicators of hydric soil conditions in this document, (Land Resource Region (LRR) A that includes Western Washington), are presented here in an abbreviated form and include: Purpose and Approach Continued Field indicators of hydric soil conditions in this document, (Land Resource Region (LRR) A that includes Western Washington), are presented here: (1) ALL SOILS: At.

Indications of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and reducing conditions, respectively. Areas that are seasonally saturated and/or inundated to the surface for a consecutive number of days for more than 12.5% ofthe growing season are wetlands provided the soil and vegetation parameters are met. Areas wet between 5% and 12% of the growing season in most years mayor may not be wetlands. Areas saturated to the surface for less than 5% of the growing season are non-wetlands. Wetland hydrology exists if field indicators are present. Field indicators of wetland hydrology may include, but are not limited to visual observations of inundation, ponding, soil saturation, oxidized root channels (rhizospheres) associated with living roots and rhizomes, watermarks, drift lines, water-borne sediment deposition, or wetland drainage patterns. The growing season starting and ending dates are required to evaluate hydrologic data. For wetland determinations, the growing season is determined using the local SCS county soils surveys. Generally, the growing season is calculated based on the "28 degrees F or lower" temperature threshold at a frequency of "5 years in 10". For much of western Washington at low elevations, the mesic growing season (March I to October 31) has been considered a good rule. However, in some areas of the Puget Sound Lowlands and coastal areas the growing season occurs all year round because the soil temperature at 19.7 inches below the soil surface is higher than 41 degrees F.

Wetland Rating Form _. western Washington version 2 2 August 2004 '" Wetland name or number (('&&r~# A".. ~ o:;t)~) Classification of Wetland Units in Western Washington 1. A~e water levels in the entire unit usually controlled by tides (Le. except during floods)? ~ go to 2 YES - the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. Ifit is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. . Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. @- go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores ofa body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m)? @=gO to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be very gradual), _The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. !/' The water leaves the wetland without being impounded?

NOTE: The riverine unit can contain depressions that are filled with water when the river is anotflooding. l~- go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, ifpresent, is higher than the i~r of the wetland ~ go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious n.a~ outlet. ~ go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more ofthe total area of the wetland unit being rated. If the area ofthe class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. a e- nncre Depressional + Riverine along stream within boundary De ressional + Lake-frin re Salt Water Tidal Fringe and any other class offreshwater wetland If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.
