Introduction Marine Surveys & Assessments (MSA) was authorized by the potential property owner, Catherine Carmella, to assess a wetland area within a parcel in Jefferson County, Washington. The wetland lies outside the limits of the neighboring City of Sequim, and as such was rated, assigned a buffer as specified by the Jefferson County municipal code, and delineated to the extent that it crosses onto the parcels in question. All field work was completed on March 3, 2018, with GIS, mapping, and subsequent report writing completed over the days of March 12 - 16, 2018. The property is an unnumbered lot located at the southeastern corner of Sunshine Drive and W Road, in Sequim WA, and consists of one parcel (002283032), which is located in the SW 1/4 SEC 28, T30N, R2W (Figure 1). II. General Site Conditions This property in question is currently made up of one previously undeveloped lot located within a relatively rural and undeveloped section outside the city limits of Sequim. It is approximately 7.5 miles ENE of Sequim, WA. The parcel is comprised of approximately 5 acres, which currently hold one temporary structure (a metal shipping/storage container). The parcel, which slopes gently to the northeast at less than 10 degrees, was heavily logged between July 2016 and July 2017; approximately 20% of the total area retains the previous state of vegetation, while the rest is largely open and bare. The parcel is bordered on the southern side by a small Washington Department of Ecology (WDOL) utility holding, as well as Gardiner Beach Road. To the north is W Road, which runs along the entirety of the northern property line. To the west, the parcel is bordered by Sunshine Drive, and to the east is significant undeveloped woodland, similar to that which existed prior to the parcel being logged. Just east of the northeastern corner of the parcel, Eagle Creek flows northeast and empties into Discovery Bay within .70 miles. On a site visit on February 9th 2018, hydrophytic vegetation (Juncus effusus, Equisetum hyemale) was discovered in a depression within the northeastern corner of the parcel. Said hydrophytic vegetation, coupled with geomorphic positioning, the presence of flowing water within and contiguous to the parcel, suggested that a wetland was likely present. This necessitated a wetland rating and delineation, which completed on March 3rd, 2018. Carmella Wetland Report 3 1 M 8 A III. Site Information Natural Resources Conservation Services Soil Query Ap oximatel 5.0 acres, 1parcel: See Figure 3 Soil Map Code Soil Name Percent AgB Agnew Silt Loam, 0 to 8 percent slopes 6.4 CmC Clallam Gravelly Sandy Loam, 1 to 15 percent slopes 69.1 TuC Tukey Gravelly Loam, 1 to 15 pecent slopes 24.6 The Agnew series consists of very deep, somewhat poorly drained soils that formed in glaciomarine sediments, typically found on terraces and terrace escarpments. Slope variation is wide, with typical slopes of 0 to 50 percent. Agnew soils are inextensive, and are typically only found in northeastern Olympic Peninsula region of Washington, primarily in eastern Clallam and western Jefferson counties. Agnew soils are formed in glaciomarine sediments, which are found in mild marine climates having cool, dry summers and cool, moist winters. They are typically characterized by being somewhat poorly drained, with slow runoff and moderately slow to slow permeability. Vegetation supported by this soil series is typically characterized by douglas fir, red alder, western red cedar, western hemlock and bigleaf maple; understory species include salal, elderberry, western sword fern and bedstraw. The Clallam series consists of moderately deep to densic materials, formed in glacial till over very compact glacial till, typically found on glaciated hills and having slopes of 0 to 30 percent. Typical elevations are 25 to 1,800 feet where the marine climate is typified by cool, moist summers and cool, moist winters. Average annual precipitation is 16 to 30 inches, occurring mostly as rain in the winter. Average January temperature is about 37 degrees F, average July temperature is about 59 degrees F, and the mean annual temperature is about 48 degrees F. The Clallam series is Moderately well drained; moderately rapid permeability above the very compact glacial till (A and Bw horizons), with very slow permeability within in the very compact glacial till (Cd horizons). The Clallam series is moderately extensive, ranging across the northeastern Olympic Peninsula and Puget Sound valleys of Washington. Native vegetation is predominantly douglas fir with some western hemlock, grand fir, western redcedar, red alder, and Pacific madrone. Understory species include salal, evergreen huckleberry, red huckleberry, Oregon grape, creambush oceanspray, long -tube twinflower, rose, blackberry, western sword fern, and western bracken fern. The Tukey series consists of moderately deep to a cemented pan, moderately well drained soils formed in glacial till on till plains and foothills. Slopes are typically 0 to 30 percent, with an average annual precipitation of 17 to 25 inches. The range of the series is small, as it is found only in Jefferson County Washington, about 1 mile west of Gardner and about 180 feet south of US Highway 101. Tukey soils are typically moderately well drained; runoff is slow to medium, with moderate permeability above the cemented till and slow to very slow permeability within the cemented till. Resulting from the very slow permeability within the cemented till, a perched water table is often found above the cemented till and can be as high as 1.5 to 3.0 feet at times from November to April. Native vegetation is douglas fir, western red cedar, red alder, western Carmella Wetland Report 4 1 141 S 1 hemlock and grand fir, with an understory of Oregon grape, salal, evergreen huckleberry, western bracken fern, western sword fern, red huckleberry, and vine maple. National Wetlands Inventory Query The United States Fish and Wildlife National Wetlands Inventory map shows five mapped wetland types (Figure 2) within .1 miles: one Palustrine Emergent Persistent Temporarily Flooded wetland and one Palustrine Unconsolidated Bottom Permanently Flooded Diked/Impounded wetland (Figure 2). These wetland types are classified by the NWI according to the Cowardin classification system, respectively, as PEM1A, PUBHx, PEM1C, PFOC, R5UBH, R4SBC. National Wetland Inventory code interpretations are as follows: P: System PALUSTRINE: The Palustrine System includes all nontidal wetlands dominated by trees, shrubs, emergents, mosses or lichens, and all such wetlands that occur in tidal areas where salinity due to ocean derived salts is below 0.5 ppt. Wetlands lacking such vegetation are also included if they exhibit all of the following characteristics: 1) are less than 8 hectares ( 20 acres ); 2) do not have an active wave - formed or bedrock shoreline feature; 3) have at low water a depth less than 2 meters (6.6 feet) in the deepest part of the basin; 4) have a salinity due to ocean -derived salts of less than 0.5 ppt. • R: System RIVERINE: The Riverine System includes all wetland and deep -water habitats contained within a channel, with two exceptions: (1) wetland dominated by trees, shrubs, persistent emergent, emergent mosses, or lichens, and (2) habitats with water containing ocean -derived salts of 0.5 ppt or greater. A channel is an open conduit either naturally or artificially created which periodically or continuously contains moving water, or which forms a connecting link between two bodies of standing water. • 5: Subsystem UNKNOWN PERENNIAL: This Subsystem designation was created specifically for use when the distinction between lower perennial, upper perennial, and tidal cannot be made from aerial photography and no data is available. • 4: Subsystem INTERMITTENT: This subsystem includes channels that contain flowing water only part of the year. When water is not flowing, it may remain in isolated pools or surface water may be absent. • FO: Class FORESTED: Characterized by woody vegetation that is 6m tall or taller. • SB: Class STREAMBED: Includes all wetland contained within the Intermittent Subsystem of the Riverine System and all channels of the Estuarine System or of the Tidal Subsystem of the Riverine System that are completely dewatered at low tide. Carmella Wetland Report 5 1 M S A • UB: Class UNCONSOLIDATED BOTTOM: Includes all wetlands and deep -water habitats with at least 25% cover of particles smaller than stones (less than 6-7 cm) and a vegetative cover less than 30%. • EM: Class EMERGENT WETLAND: characterized by erect, rooted, herbaceous hydrophytes, excluding mosses and lichens. This vegetation is present for most of the growing season in most years. These wetlands are usually dominated by perennial plants. All water regimes are included except subtidal and irregularly -exposed. • 1: Subclass PERSISTENT: Dominated by species that normally remain standing at least until the beginning of the next growing season. This subclass is found only in the Estuarine and Palustrine systems. • A: Water Regime TEMPORARILY FLOODED: Surface water is present for brief periods (from a few days to a few weeks) during the growing seasons, but the water table usually lies well below the ground surface for most of the season. • H: Water Regime PERMANENTLY FLOODED: Water covers the substrate throughout the year in all years. • C: Water Regime SEASONALLY FLOODED: Surface water is present for extended periods especially early in the growing season but is absent by the end of the growing seasons in most years. The water table after flooding ceases is variable, extending from saturated to the surface to a water table well below the ground surface. + h: Special Modifier DIKED/IMPOUNDED: These wetlands have been created or modified by a man-made barrier or dam that obstructs the inflow or outflow of water • x: Special Modifier EXCAVATED: wetlands basins or channels that have been excavated by humans. The NWI map documents were prepared primarily by stereoscopic analysis of high altitude aerial photographs taken in 1980 and 1981. Wetlands were identified on the photographs based on vegetation, visible hydrology, and geography. The aerial photographs typically reflected conditions during a specific year and season when they were taken. Some small wetlands and those obscured by dense forest cover may not be included on the map. In addition, there is a margin of error inherent in the use of aerial photographs. As evident in the attached delineation results, the actual Cowardin classification of the wetlands found did not differ greatly from those on the USFWS NWI map (Figure 2). IV. Wetland Assessment Methods Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 2011 Manual), preliminary Cannella Wetland Report 6 1 M S A information was gathered on the project site prior to the field review, rating and delineation. General information sources included: +� 1974 National Wetland Inventory (NWI) maps, United States Fish and Wildlife Service (USFWS) * 1975 Soil Survey of Snohomish County Area, Washington (USDA) • 2013 Washington Department of Natural Resources Water Resource Map (DNR) * 1979 Washington State Wetlands Identification and Delineation Manual, (WSDE) * Snohomish County municipal code, as of July 11, 2017 * 2014 State of Washington 2014 Wetland Plant List US Army Corps of Engineers (COE) • 2014 Washington State Wetland Rating System for Western Washington 2014 Update. (Hruby, T Washington State Department of Ecology) The field delineation followed the methodology outlined in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual (effective January 1987): Western Mountains, Valleys and Coast Region 9 Version 2.0) U.S. Army Corps of Engineers. This is standard manual, used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act and the Growth Management Act in Washington State. The field rating followed the methodology outlines in the Washington State Wetland Rating System for Western Washington; 2014 Update field manual, published by the State of Washington Department of Ecology. The specified buffers, identified in accordance with each individual wetland's rating score, are specified in Snohomish County Code, Chapter 30.62A.320, Table 2b: Wetland Buffer Widths. The extent and location the wetland were determined during field work completed on January 9th, 2018. Field work was done under variable conditions with an ambient temperature ranging between 45° to 55° Fahrenheit. The time of year and recent precipitation history were considered in assessing the extent of the suspect wetlands presumed to exist on site: conditions were deemed seasonal and typical of this region, this time of year. Specific field methodology used in determining the extent and location of wetland areas include: 1) As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas. 2) Wetland and upland sample plots were established in the identified potential wetland areas and in the adjacent upland areas; and Carmella Wetland Report 7 1 M S A 3) The extent of the wetlands was located with a GPS unit and measured on the ground to reference points. V. Wetland Delineation Wetland delineation establishes the specific boundaries of a wetland for the purposes of federal, state, and local regulations. In determining these physical parameters of each individual wetland, indicators of vegetation, soils, and hydrology are analyzed to assess critical areas. By defining the transition zone between scientifically established upland and wetland indicators, an established accurate boundary of the wetland can be identified between a pair of data points; one representing the upland and one representing the wetland. It is common for paired data points, when linked to vegetative indicators (such as an obvious transition line of upland grass into an emergent herbaceous community), to inform the identification of the wetland delineation. A delineation, often in conjunction with a subsequent rating, is a necessary procedural step in obtaining information which will inform subsequent construction. The wetland on the proponent's property was delineated for reasons of potential future construction; the property owner identified locations as potential building spots on the property, and therefore opted to obtain accurate wetland boundaries to inform potential building footprints. The wetland was delineated using three standard paired wetland test plots. Each test plot consisted of two data points, designated "Dry" (D) and "Wet" (W). Each data point consisted of a test pit dug to standard depth of 18 inches, to expose a representative soil profile. Each data point was then assessed for the presence of three wetland indicators: hydrophytic vegetation, hydric soils, and wetland hydrology. Following the successful location of paired data points, flags were placed between data points to mark the wetland boundary. The test pits were geo-located with GPS latitude and longitude. A. Vegetation In an effort to distinguish the types of plants that grow in different hydrologic regimes, the U.S. Fish and Wildlife Service incorporated a system of wetland plant indicator status to classify individual plant species. The wetland indicator status of a species is based on the individual species occurrence in wetlands in 13 separate regions within the United States. A plant indicator status is applied to the species as a whole, although individual variations exist within the species. Indicator categories are as follows: OBL — Obligate Wetland — Almost always occurs in wetlands under natural conditions. FACW — Facultative Wetland — Usually occurs in wetlands, occasionally found in uplands. FAC — Facultative — Equally likely to occur in wetlands or non -wetlands FACU — Facultative Upland — Usually occurs in non -wetlands, occasionally found in wetlands. UPL — Obligate Upland — Almost always occurs in uplands under natural conditions. To meet the qualification as a site dominated by hydrophytic vegetation, wetland plant species must show at least one of five hydrophytic vegetation indicators (Appendix A; Data Forms). All test plots that qualified as wet sites did so by fulfilling the same wetland vegetation indicator: all dominant species across all strata are either classified as OBL or FACW. The wetland boundary Carmella Wetland Report 8 1 M S A for this slope wetland was directly correlated to a visible vegetation line between upland and wetland species. Because the three plots were within approximately 100 feet of each other, within a discrete ecological system, vegetation species have been combined below; individual breakdown of vegetation types per sample plot are listed in the attached data sheets (Appendix A) Carmella Wetland — Sample Plots Wl, W2, W3: Vegetation Stratum Common Name Latin Name Status Tree Douglas Fir Pseudotsuga menziesii FACU Tree Red Alder Alnus rubra FAC Shrub Scotch Broom C tisus sco arius FAC Herb Horsetail E uisetum hyemale FACW Herb Bracken Fern Pteridium a uilinum FACU Herb Phragmites Phragmites australis FACW Woody Vine Himalayan Blackberry Rubus armeniacus FAC In all three wetland test plots, hydric vegetation was present (Appendix A; Data Forms).

Soils Hydric soils form under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper soil horizon (NRCS). Most hydric soils exhibit characteristic morphologies that result from repeated periods of inundation or saturation that last more than a few days. Saturation or inundation, when combined with microbial activity in the soil, causes a depletion of oxygen. This anaerobic state promotes certain biogeochemical processes, such as the accumulation of organic matter, the accumulation or reduction of iron, and other reducible elements. These processes in turn create regionally specific, visible indicators, which help identify and delineate hydric soils in a field setting. These indicators are not intended to replace or modify the requirements contained in the definition of a hydric soil; they are dynamic, and open to a degree of human interpretation. Some hydric soils lack any currently listed and accepted indicators; therefore, the lack of any listed indicator does not prevent classification of a particular soil as hydric. However, such soils and their specific morphologies, are included and specified in the necessary field guides. In this wetland, hydric soils were identified using the 201.3 Pocket Guide to Hydric Soil Field Indicators, prepared by the Wetland Training Institute, Inc, in conjunction with the Munsell Soil Color Book, a standard reference manual prepared by the Munsell Color Company and used by the United States Department of Agriculture. Wetland test plot soil findings are as follows: Hendry Wetland — Sample Plot W1 Depth (inches) Matrix Redox Features Texture Color % Color % Types Loc2 0-13" 10YR3/2 93 10YR5/6 7 C PL Loam 13-19" 10YR5/2 80 10YR4/6 25 C PL Sandy Loam 'Type: C=Concentration, Grains RM=Reduced Matrix, D=Depletion, CS=Covered or Coated Sand 2Location: PL=Pore Lining, M=Matrix Carmella Wetland — Sample Plot W2 Depth (inches) Matrix Color % Redox Features 90 % Typi ' Texture Loc2 0-10" 10YR2/2 95 10YR5/6 5 C PL Loam 10-18" 10YR4/2 90 10YR5/6 20 C PL Sandy Loam 'Type: C=Concentration, Grains RM=Reduced Matrix, D=Depletion, CS=Covered or Coated Sand 2Location: PL=Pore Lining, M=Matrix Carmella Wetland Report 10 1 1,10 S A Hendry Wetland — Sample Plot W3 Depth (inches) Matrix Redox Features Texture Color % Color % Type' Loc2 0-15" 10YR2/2 90 1OYR 5/6 10 C PL, M Loam 151- IOYR 4/2 75 1 OYR5/6 25 C PL, M Sandy Loam 'Type: C=Concentration, RM=Reduced Matrix, D=Depletion, CS=Covered or Coated Sand Grains 2Location: PL=Pore Lining, M=Matrix In all wetland test plots (WI, W2, W3) hydric soil indicators were: Sandy Redox (S5). In all upland test plots, soils were determined to be a sandy loam (See Appendix A; Data Forms). C. Hydrology Hydrologic conditions result from the interactions between meteorological, surface and ground water, as well as physical and biological factors that influence the flow, quality, or timing of water. Therefore, the determination of the presence of hydrologic conditions focuses on the corresponding presence of factors that most directly influence the persistence of water in a specific area. Similar to the indicators used in hydric soils, and because watersheds vary tremendously across the country, regional hydrologic indicators are used to more easily identify wetlands in the field. Wet test plots displayed the same three primary and secondary hydrology indicators: High Water Table (A2), Saturation (A3), Geomorphic Position (D2), with Wet Plot 3 showing also Raised Ant Mounds (D6); field observations of Surface Water Present, Water Table Present, Saturation present (depths are included in Appendix A; Data Forms). All dry test plots displayed no primary or secondary Indicators for wetland hydrology (Appendix A; Data Forms). VI. Wetland Rating Cannella Wetland: Slope, Category 3. Buffer for "Moderate Land Use" (single-family residential homes on parcels of one acre or larger): 110' Carmella Wetland Report 11 I M S a The intent of a rating is to provide a basis for protecting and managing wetlands; this is accomplished assessing a wetland's valued functions and resources -- ecological, economic, or aesthetic. In the process of a rating, a wetland is placed in a Hydrogeomorphic (HGM) Class, or a classification of wetland type, and a Category, or a numerically scored quantification of its functions and specific attributes such as rarity, sensitivity to disturbance, and the functions they provide. Based upon this score, the wetland is placed in Category 1 through Category 4; the former is a wetland of greatest value, based upon the rating rubric's characterization of its inherent value, while the latter is a wetland of least value. A specific buffer, identified in accordance with each individual wetland's rating score, is then recommended, using standardized and established guidelines. While all wetlands provide some functions and resources that are valued, be they ecological or aesthetic, they also vary widely; consequently, the recommended buffer, identified in accordance with each individual wetland's rating score, reflects that particular wetland and its specific qualities. In accordance with the Washington Department of Ecology Wetland Rating System for Western WA: 2014 Update, rating categories are divided into four grades, in order of descending buffer size: Category I with total scores of 23-27; Category II with total scores of 20-22; Category III with total scores of 16-19; Category IV with total scores of 9-15. The category of wetland based on functions is rated by the following parameters: 1) Water Quality Functions: a wetland's potential to improve water quality a) Potential of the wetland to improve water quality of and surrounding the wetland. b) Potential of the wetland to support the water quality function of and surrounding the wetland. (This parameter regards the ability of the wetland to mitigate for and lessen the toxicity of potential pollutants on and surrounding the wetland). c) Potential of local water quality improvement provided by the wetland to benefit adjacent waters. 2) Hydrologic Functions: a wetland's potential to improve hydrology a) Potential to reduce flooding and erosion b) Potential of wetland to support the hydrologic functions of the site (this parameter regards the ability of the wetland in reducing the toxicity of potential pollutants on- site and up -gradient of the wetland). c) Potential of wetland to help capture surface water that might otherwise flow down - gradient into areas where flooding might occur. 3) Habitat Functions: a wetland's potential to provide important habitat/ecological value a) Potential of the wetland to provide habitat for natural living systems. b) Potential of the accessible and undisturbed habitat and land use intensity surrounding the wetland to support the habitat functions of the site. Cannella Wetland Report 12 1 M S A c) Value of wetland to society; degree to which it provides habitat for species valued in laws, regulation, or policy. The Hendry wetland was determined to fall into the class of HGM Class: Slope, Category 3. According to the Washington State Wetland Rating System for Western Washington 2014 Update (Hruby 2014), "Slope wetlands occur on hill or valley slopes where groundwater surfaces and begins running along the surface, or below the surface. Water in these wetlands flows in one direction (down the slope) and the gradient is steep enough that the water is not impounded." "Slope wetlands do not impound water in very small depressionsl that may form on the surface", as the water is often found as sub -surface sheet flow. They are often associated with the outskirts/transitional zone of riverine wetlands, which was observed close to the proponent's property line. According to the Jefferson County municipal code [28.22.330(2), Table 2B], the proposed land use is to be "moderate impact" land use (a single-family residential home on one acre or larger). Specified in the same Jefferson County municipal code, a Category 3 wetland with a habitat score of 7, for moderate impact land use, is specified as requiring a buffer of 110 feet. VII. Summary This wetland report documents the presence of one wetland on one parcel of land belonging to Catherine Carmella, in Jefferson County, Washington. It was rated, delineated, and mapped. It was given a buffer as according to specifications in the Jefferson County Municipal Code for Category 3 wetlands with moderate impact land use, which is 110'.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple. HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. Are the water levels in the entire unit usually controlled by tides except during floods? NO -,go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 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. rNO 7 go to 3 YES - The wetland class is Flats - Tj�our wetland can be classified as a Flats wetland, use the form for Aepressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). ANO go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? L""The wetland is on a slope (slope can be verygradual), ✓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 toeing impounded. NO - go to 5 OFS 7'The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _,The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - 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 natural outlet. NO - 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 classes. 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 the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM 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. MGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.
