The school is proposing to redevelop their property into an education center. The combined land use will include tenant improvements to the existing recreation building, preservation of the existing sanctuary/church, possible renovation of one or more of the existing structures and future construction of new educational buildings. The proposed development includes additional parking and will be located south of NE 124th Street and east of Redmond Woodinville Road NE, in Redmond, Washington. 1.1 Project Location The Willows Preparatory School property is located at the northern edge of the city limits, in King County at 12348 Redmond Woodinville Road NE, within the city limits of Redmond, Washington (Figure The study area is located immediately east of Redmond Woodinville Road NE and immediately south of NE 124th Street (Figure 1.2 Site Description/Existing Conditions The study area is bordered to the north by NE 124th Street, to the east by a steep ravine, vacant lots and developed residential properties, to the south by residential development and NE 120th Way, and to the west by Redmond Woodinville Road NE. The proposed development involves two partially developed parcels (King County Assessor’s Parcels 262605‐9019 and 262605‐9071) that are about 12.81 acres in area, located in the southern portion of the study area. The subject property is mostly developed and has been cleared for buildings, access roads, driveways and parking lots. Onsite vegetation consists mostly of landscape plantings and open lawn areas, with some volunteer vegetation around a detention pond at the north end and volunteer alders at the approximate center of the study area. A portion of the site was used as a commercial dairy (Theno’s Dairy), which is now closed. The remaining buildings used for this business are proposed to be removed as part of the planned site improvements. Two areas that met the criteria for wetlands (Wetland A and Wetland hydrology, soils and vegetation, were delineated onsite (Figure 2) and were determined to be manmade based on a review of historical photographs, which show that the wetlands were unintentionally created by development and did not exist prior to development of the site in 2007 (Appendix The manmade wetlands are impounded on all sides and were created by the development of roads, access drives, parking lots, commercial and residential development, and the existing sanctuary. There are no undeveloped areas in the immediate vicinity of the wetlands. There is a grassy knoll onsite that borders Wetland A to the southwest, and an undeveloped forested area with a Class II stream (City of Redmond) located approximately 150 feet to the east of Wetland A and more than 350 feet to the east of Wetland B. Wetland A is separated from the forested area by a parking lot. Areas to the northwest of the study area are predominately farmland. Areas to the north are residential and areas to the west are recreational. The area to the east of the study area is mostly undeveloped and forested. There is a steep ravine to the east of the study area that conveys Kensington Creek; a tributary to High School Creek. The project parcels are zoned R‐1 at the north end of the study area and R‐4 in the southern portion, per the City of Redmond Zoning Map. The City of Redmond Comprehensive Land Use designation is Semi‐rural at the north end and Single‐Family Urban in the southern portion of the study area. ATTACHMENT 7 ---PAGE BREAK--- 2 The topography of the site is rolling with a small area of steeper slopes (approximately 29 percent) in the approximate center and northeastern portions of the area (Figure There are retaining walls, supporting hillslopes most likely created during development of the site. Historical photos do not show the presence of retaining walls or hillslopes prior to development of the site in 1990 (Appendix There are five detention ponds, constructed after 2006/2007, located within the study area; four concrete lined ponds are located at the west entrance to the study area, off of Redmond Woodinville road. The fifth pond is located at the north end of the study area. The northern pond has accumulated silt and contain cattails and willows. Overflow from the pond drains to the north by way of a piped drainage system. Water levels in the pond were well below the overflow pipe at the time of investigation. Some areas of the pond are rock lined. Photographs for all five detention ponds are provided in Appendix C. Weather conditions during the January and February 2016 site investigations were partly cloudy and dry with temperatures in the low to mid‐40s. Site conditions were wet due to moderate to heavy rainfall two to three days preceding the site investigation. 1.3 Project Description The Willows Preparatory School has existed since the 1990s. The school eventually purchased all five of the parcels located in the southeast corner of the intersection of NE 24th St. and Redmond Woodinville Road. The school proposes to develop some areas of these five parcels into a combined religious and education center. The combined land use will include tenant improvements to the existing recreation building, preservation of the existing sanctuary/church, possible renovation of one or more of the existing structures, as well as future construction of new educational buildings, access drives and additional parking.

The study area was surveyed using the guidelines put forth in the Corps of Engineers Wetlands Delineation Manual for the Western Mountains, Valleys, and Coast Region (Version 2.0, May 2010), as required by the Corps of Engineers and the City of Redmond. Wetlands were rated and classified using the Washington State Department of Ecology (Ecology) Wetland Rating System for Western Washington (2014 update). Soils were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts. Wetlands were flagged with pink “Wetland Delineation” flagging and labeled using a consecutive alpha‐numerical system. Data points were labeled SP‐1, SP‐2, etc. Flagging locations were mapped in the field using a handheld Topcon Tesla‐Geo Model 2‐5M. Wetland Data and Rating Forms are provided in Appendices A and B. Desktop research and onsite wetland delineation was performed by Eilean Davis, Senior Planner and Certified Wetland Management Scientist at PACE Engineers. 3.0 DESKTOP REVIEW AND SITE OBSERVATIONS Before conducting the onsite field investigation, a literature and website review was conducted to review and identify existing information on soils, wetlands, site topography, wildlife presence and other critical area and site data within the study area. A list of the resources used are listed below: • U.S. Geological Survey (USGS) topographic map (USGS, 2011) • National Wetlands Inventory map of project area online version located at: http://www.fws.gov/wetlands/Data/mapper.html) • Web Soil Survey (USDA) located at: http://www.or.nrcs.usda.gov/pnw_soil/wa_reports.html • City of Redmond Critical Areas Regulations, RCZ 21.64, found at http://online.encodeplus.com/regs/redmond‐wa/doc‐ viewer.aspx?secid=1046&keywords=21.64#secid‐1046 • City of Redmond Standard Maps, found at http://www.redmond.gov/Government/MapsGISservices/StandardMaps • City of Redmond Stream Map & Data, Stream Classification Map (2016) found at http://www.redmond.gov/common/pages/UserFile.aspx?fileId=43267 • Hydric Soils List King County Area Washington (NRCS, 2014) • Western Mountains, Valleys, and Coast, 2014 Regional Wetland Plant List, http://wetland_plants.usace.army.mil/ • WDFW Priority Habitats and Species Maps – online version located at: http://wdfw.wa.gov/mapping/phs/ • U.S Fish and Wildlife Service, Information for Planning and Consultation (IPaC), 3.1 Existing Site Documentation The following information was gathered during initial desktop research and review of available information. 3.1.1 USDA Natural Conservation Resources Service Soil Survey ATTACHMENT 7 ---PAGE BREAK--- 10 Soils within the study area are classified as Alderwood gravelly sandy loam, Bellingham silt loam, and Kitsap silt loam. These soils are listed as hydric on the 2014 National Hydric Soils List (USDA Natural Resources Conservation Service Soils, National Hydric Soils List, 2014). Alderwood soils are described as moderately well drained formed in glacial drifts or outwash or dense glaciomarine deposits. Kitsap soils are also moderately well drained and formed in lacustrine deposits with a minor amount of volcanic ash. Bellingham soils are described as poorly drained in alluvium. Kitsap soil areas are classified as “Farmland of statewide importance”. Alderwood and Bellingham soils are classified as “Prime farmland if irrigated”.

However, there is a palustrine emergent wetland located roughly 500 feet northeast of the study area as well as four other palustrine wetlands; forested, scrub‐ shrub, open water, and emergent, located north of the study area, north of NE 124th Street, within 500 feet of the study area. (Figure Portions of these NWI wetlands appear to have been replaced by development activities. 3.1.3 City of Redmond & King County Inventoried Wetlands and Streams A review of the City of Redmond Critical Areas Map indicates the presence of a wetland offsite to the east of the study area. This system does not show up on either the NWI maps or the King County Critical Areas maps. No wetlands are shown within the study area (Figure The City of Redmond Streams Classification Map (March 2016) indicates the presence of a Class II stream (Kensington Tributary) located offsite to the east that has been culverted under NE 124th Street that most likely, eventually connects to the wetland complex located to the north/northeast (Figure 6A). The stream is a tributary to High School Creek, which eventually flows to the Sammamish River. King County and City of Redmond information available on the County and City websites does not indicate the presence of fish in Kensington Tributary and information from the U.S. Fish and Wildlife IPaC system indicates that no critical habitat exists in the project area. However, a City of Redmond Biologist has stated in written correspondence that Kensington Tributary is a Class II salmon bearing stream. The City of Redmond Critical Areas Map shows the tributary as a Class III stream at the south end. It then changes to a Class II before flowing north into the rerouted portion of the stream at the north end, where it again becomes a Class III stream. The tributary joins High School Creek at the north end. Per RZC 21.64.020, Class II streams have a 100 foot buffer plus a 50 foot outer buffer. There are no streams located within the project property (Figure The outer stream buffer (50 feet) extends onto the property in some locations, but the proposed development is well outside the 150 foot buffer Similar to the NWI map, King County iMap shows the presence of a wetland complex located north of the study area, north of NE 124th Street. In addition, King County maps identify Kensington Tributary as an unclassified stream located to the east of the site that flows northwest to the wetland complex located north of NE 124th Street. The unclassified stream is incorrectly shown on iMap to flow across the northeast corner of the site. The stream actually makes a turn to the northeast, to the rerouted portion of the tributary, away from the subject property before flowing to the northeast, under NE 124th Street and then west to the Sammamish River. (Figure 7) The culvert for the stream located to the northeast of the study area, is located just south of NE 124th Street and is shown on the Delineated Areas map (Figure 2) included with this report. The City of Redmond replaced the culvert going under NE 124th Street, located about 525 feet northeast of the proposed development, in 2010. King County is scheduled to replace the High School Creek culvert located under NE 124th Street, about 700 feet northeast of the proposed development, in 2017. ATTACHMENT 7 ---PAGE BREAK--- 14 3.1.4 City of Redmond Fish and Wildlife Habitat Map According to the City of Redmond Fish and Wildlife Habitat Conservation Areas Map, there are no fish or wildlife corridors or habitat located within or near the project study area (Figure 8) 3.1.5 Washington Department of Fish and Wildlife Priority Habitat Map A review of the Washington Department of Fish and Wildlife (WDFW) Priority Habitat Species (PHS) website, showing masked data, indicates that there is aquatic habitat mapped within the wetland complex located across NE 124th Street, north of the study area. There are no fish or wildlife corridors located within the study area. The WDFW PHS data is provided in Appendix D. 3.2 Topography Topography within the study area has been modified by past construction activity. Currently, the topography within the study area is rolling with some areas of steep slopes. These slopes were most likely created by construction when soils were stockpiled to create the detention ponds and develop the site. The steeper slope areas are retained by constructed concrete walls made of ecology block. A review of historical photos shows the site prior to development of the ponds and existing buildings without these retaining walls and steep slopes. Historical photos are provided in Appendix C. The City of Redmond has designated an area at the eastern edge of the property as an erosion hazard area (Figure 9) that is associated with the steep ravine to the east of the study area. The King County iMap shows a similar erosion hazard area in the eastern edge of the study areas (Figure 10). Rocks have been placed at the northeast corner of Wetland B to control erosion in the northeast corner of the wetland. There were indications of slight hillside sloughing observed in the hillslope located in the approximate center of the study area, just south of the existing church building and walkway.

Figure 10 Erosion Hazard Areas ATTACHMENT 7 ---PAGE BREAK--- 28 ATTACHMENT 7 ---PAGE BREAK--- 29 3.3 Uplands The upland areas within the study area boundary are predominately cleared, landscaped, and maintained with some small areas of deciduous trees; including a stand of red alder (Alnus rubra) trees and saplings in the approximate center of the study area at the southwest corner of the existing sanctuary building, a stand of alders at the northwest corner of the study area, and a small scrub‐shrub area of scotch broom (Cytisus scopariuus) and Himilayan blackberry (Rubus armeniacus) at the northeast corner of the study area. Other vegetation within the uplands include Douglas fir (Psuedotsuga menzeisii), and non‐native grasses such as bentgrass (Agrostis sp.), fescue (Festuca sp.), and reed canarygrass (Phalaris arundinacea). The area also contained a large percentage of moss. Soils within sample pits dug in upland areas around Wetland A generally consisted of silt loam soils with a great deal of sand, gravel, and cobbles, with a Munsell soils color of mostly 10YR 4/3. Soils within sample pits dug in upland areas around Wetland B were clay loam with sand, gravel, and cobbles, and a Munsell soils color of 10YR 4/3. Soils within the upland areas were dry. 3.4 Wetlands Two wetlands (Wetland A and Wetland B) were delineated onsite by PACE staff during site investigations conducted in January and February 2016. Delineated areas are depicted in Figure 2. Because the delineated wetlands have been determined to be manmade and regulation is not suggested, buffers are not shown. 3.4.1 Wetland A Wetland A is an approximately 0.25 acre manmade slope wetland located at the eastern edge of the study area, south of and immediately adjacent to the sanctuary building. The slope wetland is located at the base of a hill slope, confined by a parking lot and walkway to the east and north. Based on field investigations and review of historical aerial photos of the site, the wetland appears to be manmade and was most likely created unintentionally when the sanctuary building and adjacent parking lot and walkways were constructed. Past construction activity has resulted in the excavation, redistribution, and compaction of soils on site. The soils excavation and redistribution that occurred south of the sanctuary building during construction more than likely created the hillslope. Runoff from the hillslope to the southwest of the wetland, created during development, and adjacent impervious surfaces, flows easterly and northerly where it is impounded by the walkway and curb before flowing west along the depressional area adjacent to the walkway curb before entering the City’s stormwater system to the west. Figure 2 shows the drainage pattern from the wetland to the stormwater system within Redmond‐Woodinville Road to the west. See Appendix C for site photos showing historical site conditions and construction activities that unintentionally created the wetland conditions. Vegetation in Wetland A met the criteria for wetland vegetation and is dominated by bentgrass (Agrostis sp.), lamp rush (Juncus effusus), reed canarygrass (Phalaris arundinacea), fescu (Festuca sp.), and creeping butter cup (Ranunculus repens), with Red alder (Alnus rubra) and other non‐native grasses. There is also a large percentage of moss. ATTACHMENT 7 ---PAGE BREAK--- 30 Three soil pits were dug within the wetland; SP1, SP3 and SP5 and revealed silt and sandy loam soils. Soils within the wetland met the criteria for hydric soils with Munsell Soil colors of 10YR 3/1 and 10YR 3/2 and redox features of 7.5YR 4/6, 7.5YR 4/8, and 7.5YR 5/8. Soils were saturated to the surface. Hydrology within the sample pits also met the wetland criteria with surface water of less than 0.25 inches and surface water of between 0.25 to .5 inches in the wetland at the time of investigation. Wetland A extends downslope from the southeast corner of the wetland, and flows in one direction (northeast) to the bottom of the hill slope, where it is contained by a concrete curb. A drainage channel has been excavated immediately adjacent to the concrete curb, and holds water before directing flows to the west. The wetland’s source of hydrology is precipitation and hillside seepage; water was observed seeping into the sample pits and there had been about three days of heavy rain preceding the site investigation. Using the Cowardin classification method (Cowardin et al, 1979), Wetland A, though manmade, would be classified as a Palustrine Emergent Seasonally Saturated Excavated (PEMBx). The small percentage of Red alder located at the northwest corner of the wetland provides very little cover for the wetland. Using the Washington State Department of Ecology (Ecology) Revised 2014 Wetland Rating System, and rating the wetland as a slope wetland, Wetland A would be a Category IV wetland with a total score of 15 (water quality 6, hydrology 5, habitat The wetland scores low values for water quality and hydrologic function due to a lack of water quality improvement potential and lack of potential to improve flooding. The habitat value in Wetland A is rated low to moderate for its lack of plant diversity and potential to support habitat functions. Because the area met the wetland criteria, wetland data and rating forms were completed and are provided in Appendices A and B. The habitat score for this wetland is 4. Per City of Redmond Zoning Code, RZC 21.64, a Category IV wetland with a low habitat value, in a high impact land use area requires a 50 foot buffer. However, the wetland is manmade and the buffer for Wetland A has been impacted by development and regular mowing. Photographs of the area delineated as Wetland A and historical photos showing development of the area are provided in Appendix C. 3.4.2 Wetland B Wetland B is an approximately 0.05 acre depressional wetland, also manmade; created by development, located on the north end of the study area, south of and adjacent to NE 124th Street. Based on historical photos, this wetland also appears to be manmade, impounded by a constructed earthen berm that unintentionally created the depressed area. Past construction activity has resulted in the excavation, redistribution, and compaction of soils within this location. Review of historical aerial photos confirms this activity (Appendix ATTACHMENT 7 ---PAGE BREAK--- 31 Vegetation in Wetland B met the criteria for wetland vegetation and is dominated by reed canarygrass (Phalaris arundinacea) and fescu (Festua sp.) with some lamp rush (Juncus effusus) and moss. Two soil pits were dug within the wetland (SP7, SP9) and revealed silt loam soils. Soils within the wetland met the criteria for hydric soils with Munsell Soil colors of 10YR 2/1 and 10YR 3/1 and redox features of 10YR 4/6 and 7.5YR 5/4. Soils within the wetland were saturated to the surface with about 2.5 inches of surface water present in the wetland at the time of the site investigation. Water is impounded within the depressional area before draining to the east and eventually flowing across two adjacent residential properties to the offsite stream located about 350 feet to the east of the study area. Cobble has been placed at the outflow location (Figure most likely to prevent erosion on the slope. The source of hydrology in the wetland is mostly precipitation and runoff from the asphalt surfaces to the south. Figure 2 shows the location of the wetland and the drainage at the northeast corner. Using the Cowardin classification method, Wetland B, though manmade, would be classified as a Palustrine Emergent Seasonally Saturated Excavated (PEMBx). Nearby trees provide little if any cover for the wetland. Using the Washington State Department of Ecology (Ecology) Revised 2014 Wetland Rating System, and rating the wetland as a depressional wetland, Wetland B would be a Category III wetland with a total score of 18 (water quality 7, hydrology 6, habitat The wetland scores moderate values for water quality and low values for hydrologic function due to a lack of water quality improvement potential and lack of potential to improve flooding. The habitat value in Wetland B is rated low to moderate for its lack of plant diversity and potential to support habitat functions. Because the area met the wetland criteria, wetland data and rating forms were completed and are provided in Appendices A and B. The habitat score for this wetland is 5. Per City of Redmond Zoning Code, Title 21.64, a Category III wetland with a low habitat value in a high impact use area requires a 150 foot buffer. However, the wetland is manmade and the buffer for Wetland B has already been impacted by development. Photographs of the area delineated as Wetland B and historical photos showing development of the area that most likely created the wetland conditions, are provided in Appendix C. 3.5 Aquifer Recharge Areas/Wellhead Protection Zones Per the City of Redmond Wellhead Protection Zones map and Property Viewer information, the study area is not located within a critical aquifer recharge area. However, per RZC 21.64.050, all areas of the City not located within Protection Zones 1, 2, or 3, are considered to be within Zone 4 (Figure 11). RZC 21.64.050 prohibits the alteration of a critical aquifer recharge area. Development of the properties as proposed would not alter a critical aquifer recharge area. The proposed development does not propose to store, use, or produce hazardous materials that ATTACHMENT 7 ---PAGE BREAK--- 32 could be detrimental to a critical aquifer recharge area, as described in RZC 21.64.050(C). The proposed buildings will be connected to the City’s sanitary sewer system and the City’s stormwater collection system. The proposed development would not alter riparian stream corridors (RZC 21.64.020 the Class II stream to the east of the project is approximately 150 feet away from Wetland A and separated from the Category IV wetland by a parking lot and access drive. The stream is more than 350 feet away from Wetland B and separated by development. The project would also have no impact on fish and wildlife habitat conservation areas (RZC 21.64.020 frequently flooded areas (RZC 21.64.040 or geologically hazardous area (RZC 21.64.060 3.6 Wildlife No wildlife was observed during the January and February 2016 site investigations, and the study area is not known to provide habitat for any federal or state listed species. WDFW lists the wetland complex to the north of the study area as wetland habitat but does not identify a listed species. A copy of the Fish and Wildlife PHS report is provided in Appendix D.

Soils and topography, as well as drainage patterns, have been altered by development creating the slopes and wetlands. Therefore mitigation is not proposed. Historical photos have been provided in Appendix C that show the development of the site as well as the creation of Wetlands A and B and the hillslopes located at the north and west sides of the site. The currently proposed development would not alter Wetlands A or B, and would not result in a loss of function and value. If future additional development is proposed, potential impacts could occur, which could require mitigation under RZC 21.64.030 C and the any proposed development would be required to meet the construction standards as provided in RZC 21.64.050 D. However, both wetlands appear to be manmade and the function and value are minimal given the lack of plant diversity and potential to provide habitat. Additionally, the buffer zones for Wetlands A & B have been altered by past development. Therefore, regulation of these wetlands is not suggested. The project would also be required to meet the construction standards as provided in RZC 21.64.050 D.

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 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 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. ATTACHMENT 7 Wetland A xx x ---PAGE BREAK--- Wetland name or number Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 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 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 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. ATTACHMENT 7 Wetland B ---PAGE BREAK--- Wetland name or number Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 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.
