Phone: 425.223.7482 Via email: nick@ichijousa.com Re: Renton Wolf Woods property, Wetland and Stream Delineation Report The Watershed Company Reference Number: 170511 Dear Nick: On May 15, 2017, ecologists, Sam Payne and Katy Crandall, completed a wetland and stream delineation study located at 1815 Nile Avenue NE, Renton, WA 98059. The study area was approximately 10.95 acres and included two parcels (parcel numbers 032305- 9014 and -9047) located in the City of Renton and King County, respectively. This letter summarizes the findings of the delineation study and details applicable federal, state, and local regulations. The following documents are enclosed: • Wetland Delineation Sketch • Wetland Determination Data Forms • 2014 Ecology Rating Forms and Figures Methods Public-domain information on the subject properties was reviewed for this delineation study including the following: • USDA Natural Resources Conservation Service, Web Soil Survey (WSS) application • U.S. Fish and Wildlife Service National Wetland Inventory (NWI) maps • Washington Department of Fish and Wildlife (WDFW) interactive mapping programs (PHS on the Web, SalmonScape) • Washington Department of Natural Resources, Forest Practices Application Mapping Tool (FPARS) Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 2 • King County’s GIS mapping website (iMAP) • City of Renton (COR) maps Characterization of climatic conditions for precipitation was determined using the WETS table methodology from the USDA NRCS document Part 650 Engineering Field Handbook, National Engineering Handbook, Hydrology Tools for Wetland Identification and Analysis, Chapter 19 (September 2015). The Seattle-Tacoma International AP station as recorded by NOAA (http://agacis.rcc-acis.org/) was used as a source for precipitation data. The WETS table methodology uses climate data from the three months prior to the site visit month to determine if normal conditions are present. Wetlands The study area was evaluated for wetlands using methodology from the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 (Regional Supplement) (US Army Corps of Engineers [Corps] May 2010). The wetland boundary was determined on the basis of an examination of vegetation, soils, and hydrology. Areas meeting the criteria in the Regional Supplement were identified as wetland. Soil, vegetation, and hydrologic parameters were sampled at several locations along the wetland boundary to make the determination. Wetlands were marked with pink- and black-striped flagging. Data points were marked with yellow- and black-striped flagging. Identified wetlands within the property were classified using the 2014 Update to the Western Washington Wetland Rating System (Publication #14-06-029) (2014 Rating System). Streams The study area was also evaluated for streams based on the presence or absence of an ordinary high water mark (OHWM) as defined by the Revised Code of Washington (RCW) 90.58.030 and the Washington Administrative Code (WAC) 220-660-030. The OHWM edge was located by examining the bed and bank physical characteristics and vegetation to ascertain the water elevation for mean annual floods. Streams were marked with blue- and white-striped flagging. Onsite streams were classified using the stream typing system established by WAC 222- 16-030, per City of Renton regulations. Findings The study area is located within the Cedar-Sammamish Drainage Basin (WRIA 8), May Creek Sub-Basin; in Township 23 North, Range 5 East, Section 3. The property includes a forested ravine that slopes down to Greenes Creek. Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 3 Public-domain information reviewed for the subject properties is summarized in Table 1. Table 1. Summary of online mapping and inventory resources. Resource Summary USDA Natural Resources Conservation Service, Web Soil Survey (WSS) application Alderwood gravelly sandy loam, 8 to 15 percent slopes U.S. Fish and Wildlife Service National Wetland Inventory (NWI) maps Riverine; R4SBC Washington Department of Fish and Wildlife (WDFW), Priority Habitats and Species (PHS on the Web) No priority habitat or species Washington Department of Fish and Wildlife, SalmonScape Modeled presence of salmonids including chinook, coho, sockeye, and steelhead. Washington Department of Natural Resources, Forest Practices Application Mapping Tool (FPARS) Type F and Type N stream King County’s GIS mapping website (iMAP) Mapped stream, Unclassified per 1990 SAO City of Renton (COR Maps) Mapped stream: Greenes Creek (Type Ns), mapped wetlands Wetland A Wetland A is located on the northern parcel boundary within the Greenes Creek ravine. It includes both riverine and slope hydrogeomorphic (HGM) classifications and is considered riverine for rating purposes. Cowardin vegetation classifications include forested, scrub-shrub, and emergent. Dominant vegetation within the wetland area includes western red cedar, red alder, red- osier dogwood, salmonberry, vine maple, creeping buttercup, and velvet grass. Soils in the wetland unit were very dark (10YR 2/1 and 10YR 3/1) with abundant redoximorphic features such as iron concentrations within the top 12 inches. A hydrogen sulfide odor was detected during subsurface investigation. Hydric soil indicators Hydrogen Sulfide (A4) and Redox Dark Surface (F6) were met at the recorded wetland data point (DP-1). Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 4 Hydrology of the riverine HGM area is primarily provided by Greenes Creek and associated hyporheic groundwater. Hydrology to the slope HGM area is provided by groundwater. Wetland hydrology indicators High Water Table (A2), Saturation (A3), and Hydrogen Sulfide Odor (C1) were observed at DP-1. Figure 1. Wetland A (background) with boundary at edge of shrubs. Wetland B Wetland B is located at the southern parcel boundary associated with Greenes Creek. It is characterized by a riverine HGM classification and forested and scrub-shrub Cowardin vegetation classifications. The vegetative community consists of primarily black cottonwood, red alder, red-osier dogwood, black twinberry, salmonberry, beaked hazelnut, vine maple, piggy-back plant, and creeping buttercup. Soils in the wetland unit are dark with a 10YR 2/2 matrix in all soils layers. Redoximorphic features were not observed, however they may have been masked by dark soils. Wetland soils were saturated to the surface in the wetland area and it is likely that iron concentrations had been reduced and rendered undetectable. Due to the presence hydrophytic vegetation and strong hydrology, soils were assumed to be hydric and meeting wetland criteria. Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 5 Hydrology is provided by Greenes Creek and associated hyporheic groundwater. Wetland hydrology indicators High Water Table (A2) and Saturation (A3) were observed at the recorded data point (DP-4). Wetland C Wetland C is a ditch feature adjacent to the road with wetland characteristics that drains into Greenes Creek. It has a slope HGM classification and both scrub-shrub and emergent Cowardin vegetative classifications. It is clearly an excavated feature cut out of the surrounding upland areas. No signs of scour or other ordinary high water mark indicators were identified. The vegetative community was dominated by salmonberry, red-osier dogwood, velvet grass, and creeping buttercup. Soils were dark (10YR 3/1) with redoximophic iron concentrations in the top 12 inches. Hydric soil indicator Redox Dark Surface (F7) was met at the wetland data point (DP-6). Hydrology is provided by groundwater and surface runoff from the uphill slope area. Wetland hydrology indicators High Water Table (A2) and Saturation (A3) were observed at DP-6. Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 6 Figure 2. Wetland C, approximate boundary in yellow. Non-wetland areas The forest community is composed primarily of large Douglas-fir, western hemlock, big- leaf maple, red alder, and black cottonwood with and an understory of salal, sword fern, salmonberry, Indian plum, vine maple, and beaked-hazelnut. A dirt road runs east to west through the study area. A patch of slough sedge was found near the western edge of the property (Figure 3), but no wetland hydrology indicators were observed. Additionally, the surrounding plant community consisted of non-wetland species. This area is not a wetland area because it lacks wetland hydrology, even during a period of wetter than normal conditions. A residence is located on the eastern property area including out-structures and lawn area. Two other adjacent residences have expanded lawn and garden area into the subject property and a few trails extend throughout. Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 7 Figure 3. Slough sedge patch in a small depression surrounded by a non-wetland plant community. Greenes Creek Greenes Creek flows from south to north through the center of the ravine and drains into May Creek approximately 0.5 miles downstream. Observed flow in Greenes Creek was typically three feet wide during the site visit, although it ranged in width from approximately 1-5 feet. Water depth was approximately three inches and pools of up to one foot in depth were observed. Streambed sediments were primarily gravels, sands, and silts. The stream rests below a forest canopy that opens in a few patches of thick shrubs. Dual 2-foot metal corrugated culverts connect the stream underneath the dirt road onsite. SalmonScape identifies a modeled presence of salmonids, including federally-listed Puget Sound Chinook and Puget Sound steelhead within the study area. The Washington Department of Natural Resources FPARS Map identifies Greenes Creek as a Type F stream, indicating fish presence. However, the City of Renton identifies the stream as a Type Ns stream, indicating a non-fish seasonal watercourse. Greenes Creek is assumed to be Type F due to the proximity to May Creek, unknown quality of downstream fish passage, and modeled presence of salmonids by WDFW. Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 8 Figure 4. Greenes Creek Stream B (Unnamed Creek) Stream B is an unnamed ditched creek located just off-site to the south that converges with Greenes Creek at the southern property boundary. It flows from east to west adjacent and parallel to the south parcel boundary and curves southeast through the nearby development. The stream is identified as type ‘N’ on DNR’s FPARS and is unmapped by the City of Renton and SalmonScape. Type N indicates non-fish streams with unknown hydroperiods. Field observations indicate that the flow of Stream B is roughly equivalent to Greenes Creek at the point of convergence. As the stream was offsite, we could not take measurements on width and depth. By visual assessment, it was approximately 2 feet wide and 2 inches deep during the site visit. Based on the observed size, approximate gradient, and connectivity to Greenes Creek, Stream B should also be considered a Type F water. Local Regulations The study area includes two parcels; one is City of Renton jurisdiction, the other is King County jurisdiction. The current intent is to annex the King County parcel into the City of Renton. Therefore, City of Renton regulations are presented in this report for the entire study area. Since Wetland C is a ditch excavated from non-wetland, it likely would not be regulated by the City of Renton. Per RMC 4-3-050 “Wetlands created or restored as a part of a mitigation project are regulated wetlands. Regulated wetlands do not include those Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 9 artificial wetlands intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway.” Critical areas in Renton are regulated under Section 4-3-050 (Critical Areas) of the Renton Municipal Code (RMC). According to the RMC, wetlands are classified based on the 2014 Rating System. Wetland buffer widths are determined based upon the type of proposed land use, wetland category, and habitat score generated using the 2014 Rating System. Streams are classified based upon status as shoreline of the state, presence of fish use or fish habitat, and duration of flow. Critical area classifications, associated buffer widths, and structure setback are provided in Table 2. Table 2. Summary of wetland rating scores, critical area classifications, standard buffer widths, and structure setbacks per RMC 4-3-050. 2014 Rating System Scores Wetland Category/ Stream Type Standard Buffer Width (feet) Setback (feet) Water Quality Hydro- logic Habitat Total Wetland A 7 8 6 21 II 150 15 Wetland B 7 8 6 21 II 150 15 Wetland C* 7 6 5 18 III 100 15 Greenes Creek N/A N/A N/A N/A F 115 15 Stream B N/A N/A N/A N/A F 115 15 *May not be regulated by City of Renton. Ecology and Corps would likely regulate the loss of this wetland, if proposed. State and Federal Regulations Redevelopment of these properties that require changes to the road and stream crossing will require a Hydraulic Project Approval from WDFW. This will likely involve upgrading the culvert to a structure that complies with the WDFW Water Crossing Design Guidelines (2013). Wetlands and streams are also regulated by the Corps under section 404 of the Clean Water Act. Any proposed filling or other direct impacts to Waters of the U.S., including Wetland Delineation Report Nick Nied, Ichijo USA May 30, 2017 Page 10 wetlands (except isolated wetlands), would require notification and permits from the Corps. All delineated wetlands are non-isolated due to a hydrologic connection with Greenes Creek. Federally permitted actions that could affect endangered species may also require a biological assessment study and consultation with the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service. Compliance with the Endangered Species Act must be demonstrated for activities within jurisdictional wetlands and the 100-year floodplain. Application for Corps permits may also require an individual 401 Water Quality Certification and Coastal Zone Management Consistency determination from Ecology and a cultural resource study in accordance with Section 106 of the National Historic Preservation Act. In general, neither the Corps nor Ecology regulates wetland buffers, unless direct impacts are proposed. When direct impacts are proposed, mitigated wetlands may be required to employ buffers based on Corps and Ecology joint regulatory guidance.

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. ☒NO – 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 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 any time 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). ☒NO – 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. ☒NO – go to 5 ☐YES – 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. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. Wetland name or number: Wetland A Wetland Rating System for Western WA: 2014 Update Rating Form – Effective January 1, 2015 4 ☒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 some time 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. HGM 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 If you are still unable 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.

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. ☒NO – 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 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 any time 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). ☒NO – 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. ☒NO – go to 5 ☐YES – 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. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. Wetland name or number: Wetland B Wetland Rating System for Western WA: 2014 Update Rating Form – Effective January 1, 2015 4 ☒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 some time 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. HGM 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 If you are still unable 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.

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. ☒NO – 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 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 any time 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). ☒NO – 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. ☐NO – go to 5 ☒YES – 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. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. Wetland name or number: Wetland C Wetland Rating System for Western WA: 2014 Update Rating Form – Effective January 1, 2015 4 ☐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 some time 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. HGM 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 If you are still unable 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.
