22-102583-SE-Critical Areas Report-06-10-2022-V1 January 24, 2022 AOA-6477 Ryan Kohlmann ryan.kohlmann@pultegroup.com SUBJECT: Critical Areas Study for Alder Village, Federal Way, WA Parcels 322104-9036, -9045, -9157, -9138, -9136, 9050, -9064, -9011, and -9063 Dear Ryan: On April 8, 2021 I conducted a wetland reconnaissance on the subject property utilizing the methodology outlined in the May 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). An additional field investigation was conducted on May 13, 2021. The subject project site includes nine tax parcels located within the City of Federal Way. Existing land uses on the site include several single-family residences, undeveloped forested areas, and grazed pasture. The site is the proposed location of the Alder Village residential subdivision. 1.0 EXISTING CRITICAL AREAS Four wetlands (Wetlands B, C, D, and E) have been identified and delineated on and adjacent to the site. Wetland A is located far off-site to the southeast and is not a part of this study. I delineated Wetlands B, C, and E and Wetland D was delineated by Environmental Design, LLC (see Attachment C). All of the wetland boundaries were subsequently surveyed and are depicted on Figure 1. Attachment A contains data sheets prepared for representative locations in both the wetlands and uplands along the delineated boundaries. These data sheets document the vegetation, soils, and hydrology information that aided in the wetland boundary delineation. Wetland Rating and Habitat Points Size (s.f.)

IV 3 HP 2,398 50 Depressional Ryan Kohlmann January 24, 2022 Page 2 of 3 1.1 Wetland B Wetland B consists of a Depressional HGM class wetland located off-site to the southeast. The wetland appears to receive hydrologic support primarily from collected surface water. Overflow runoff from Wetland B drains south through a cut channel and discharges into the northern portion of Wetland A (which is located well off-site). At the time of the field investigations groundwater within the wetland was typically at the surface. Vegetation within Wetland B consisted primarily of a Palustrine Scrub-Shrub plant community dominated by willow and spirea with small forested patches consisting of willow in excess of 20 feet tall and a clump of red alder (Alnus rubra) and salmonberry in the southern portion of the wetland. Wetland B meets the criteria for a Category III wetland with 5 Habitat Points per the current City of Federal Way rating system (Attachment B). Category III wetlands with 5 Habitat Points within the City of Federal Way require a standard 80-foot buffer from the wetland edge per FWMC 19.145.420(2). 1.2 Wetland C Wetland C consists of a small Depressional HGM class wetland located in the east- central portion of the site. The wetland appears to have been historically excavated in places and is hydrologically isolated. Although dry at the time of the April and May 2021 field investigations, surface staining and hydric soils indicate likely occasional shallow ponding. Vegetation within Wetland C consisted of a Palustrine Forested plant community that included red alder, crab apple (Malus fusca), salmonberry, spirea, and creeping buttercup (Ranunculus repens). Wetland C meets the criteria for a Category IV wetland with 3 Habitat Points per the current City of Federal Way rating system (Attachment B). Category IV wetlands with 3 Habitat Points within the City of Federal Way require a standard 50-foot buffer from the wetland edge per FWMC 19.145.420(2). 1.3 Wetland D Wetland D consists of a large Depressional HGM class ponded wetland located in the western portion of the site. The wetland was delineated by Environmental Design, LLC and is fully described in Attachment C. Based on my review of this report, I concur with the conclusion that Wetland D is a Category III wetland with 5 Habitat Points. Category III wetlands with 5 Habitat Points within the City of Federal Way require a standard 80-foot buffer from the wetland edge per FWMC 19.145.420(2). 1.4 Wetland E Wetland E consists of a small Depressional HGM class wetland located in the central portion of the property. The wetland is hydrologically isolated and consists entirely of a low spot within a pasture actively grazed by cows. Although dry at the Ryan Kohlmann January 24, 2022 Page 3 of 3 time of the April and May 2021 field investigations, surface staining and hydric soils indicate likely occasional shallow ponding. Vegetation within Wetland E was sparse and consisted primarily of bare ground with patches of grazed grass and creeping buttercup. Wetland E meets the criteria for a Category IV wetland with 3 Habitat Points per the current City of Federal Way rating system (Attachment B). Category IV wetlands with 3 Habitat Points within the City of Federal Way require a standard 50-foot buffer from the wetland edge. 2.0 PROPOSED PROJECT The proposed project consists of the Alder Village residential subdivision. As part of the project, all of the wetlands and associated buffers will be preserved and protected in perpetuity within designated tracts. There are no proposed wetland impacts. Wetland buffer intrusions (if proposed as part of future engineering design) must be limited to pervious trails designed per the conditions of FWMC 19.145.440(2) and stormwater management facilities designed per FWMC 19.145.440(3). Any proposed intrusion must be limited to the outer 25% of the buffer area. Also, please note that per FWMC 19.145.420(5) all lighting should be directed away and not into the wetland buffers and that per FWMC 19.145.160 a 5-foot structure setback is required from all wetland buffers. If you have any questions regarding the delineation or ratings, please give me a call.

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 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? 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 leaves the wetland without being impounded. NO - go to 5 YES - The wetland class is Slope 5. Does the entire wetland unit meet all of the following criteria? The overbank flooding occurs at least once every 2 years. 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. 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. 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; 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. 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). The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 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. HGM Classification of Wetland in Western Washington If 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. At least 30% of the open water area is deeper than 6.6 ft (2 m). Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - March 2, 2015 Wetland name or number B NO - go to 7 YES - The wetland class is Depressional NO - go to 8 YES - The wetland class is Depressional NOTES and FIELD OBSERVATIONS: Salt Water Tidal Fringe and any other class of freshwater wetland HGM class to use in rating Riverine Depressional Lake Fringe 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. Riverine Treat as ESTUARINE Slope + Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional + Lake Fringe Riverine + Lake Fringe 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 Slope + Riverine Slope + Depressional Depressional 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. 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. 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.

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 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? 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 leaves the wetland without being impounded. NO - go to 5 YES - The wetland class is Slope 5. Does the entire wetland unit meet all of the following criteria? The overbank flooding occurs at least once every 2 years. 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. If 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. At least 30% of the open water area is deeper than 6.6 ft (2 m). HGM Classification of Wetland in Western Washington 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. 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; 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. 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). The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 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. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - March 2, 2015 Wetland name or number C NO - go to 7 YES - The wetland class is Depressional NO - go to 8 YES - The wetland class is Depressional NOTES and FIELD OBSERVATIONS: 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. 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. 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. Riverine Treat as ESTUARINE Slope + Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional + Lake Fringe Riverine + Lake Fringe 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 Slope + Riverine Slope + Depressional Depressional Depressional 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 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? 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 leaves the wetland without being impounded. NO - go to 5 YES - The wetland class is Slope 5. Does the entire wetland unit meet all of the following criteria? The overbank flooding occurs at least once every 2 years. 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. If 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. At least 30% of the open water area is deeper than 6.6 ft (2 m). HGM Classification of Wetland in Western Washington 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. 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; 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. 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). The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 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. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - March 2, 2015 Wetland name or number E NO - go to 7 YES - The wetland class is Depressional NO - go to 8 YES - The wetland class is Depressional NOTES and FIELD OBSERVATIONS: 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. 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. 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. Riverine Treat as ESTUARINE Slope + Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional + Lake Fringe Riverine + Lake Fringe 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 Slope + Riverine Slope + Depressional Depressional Depressional 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.

Olympia, Washington. 177 pp. Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above ). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p. 161 – see web link above ). Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report – see web link on previous page ). Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft (6 m) long. Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed elsewhere. WDFW Priority Habitats Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE : This question is independent of the land use between the wetland unit and the priority habitat. Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and wildlife (full descriptions in WDFW PHS report ). Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species, forming a multi-layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha) > 32 in (81 cm) dbh or > 200 years of age. Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old-growth; 80-200 years old west of the Cascade crest. http://wdfw.wa.gov/publications/00165/wdfw00165.pdf or access the list from here: http://wdfw.wa.gov/conservation/phs/list/ Wetland Rating System for Western WA: 2014 Update Rating Form -

The site was revisited on January 27, 2020 to update information regarding the wetland and to determine if the site has had any changes since the last evaluation. In order to conduct a thorough review of the site to determine if wetlands are present on the site several resources were reviewed. The project started by pulling research and reviewing the research from several sources. After review of the research it was noted that wetlands were mapped on the site. A site visit was then conducted in order to test in areas for wetland habitat. Since the site has not been disturbed for many years and is thick with vegetation, test sites were completed in areas where vegetation, elevation or other characteristics changed that indicated a possible presence of wetland habitat. Site Description: The site is located at 1224 South 376th Street in Federal Way, Washington. The site is identified by King County by the parcel number 0217154067. The site is located in Section 15 of Township 17 North, Range 02 East. The property is about 2 acres in size and varies in elevation with hills located throughout the site to the west. The site is currently vacant land with residential homes surrounding it. According to the research pulled wetland habitat is mapped on the site; however, upon inspection of the site it was noted that although the depression area has wetland habitat it appears have been constructed and is a storm water pond. The area around the sites are residential and vacant land. Methodology: A site visit was conducted on April 22, 2016 and January 27th, 2020 where Environmental Design walked the property and reviewed the site. The depression area has a gentle slope to it of about 3:1. The pond does have wetland vegetation and does meet hydrology and soil criteria. Environmental Design, LLC completed the wetland study of this site by using the Routine Determination Method according to the 1987 U.S. Army Corp of Engineers Wetland Delineation Manual and the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region. In order to complete this method first research was conducted by pulling information and maps from the National Wetland Inventory website, the King 4 Job Number: 2015-039 Client Name: Ellingson, Arnie County Website, the NRCS website to find out what the soils were and also further information was pulled from the Department of Natural Resources website. When using the Routine Approach, a wetland area must meet three specific parameters. These three parameters are hydrology, vegetation and hydric soils. Hydrology can be difficult to assess because it may or may not be present, depending on the time of year. Vegetation and soils are important to assess if there has been hydrology present in the past. If the site meets the hydrology, vegetative and hydric soil parameters then the site is considered a wetland. If one parameter is not met then the area is not considered a wetland. Observations: Vegetation: Wetland Vegetation has been classified into indicator statuses of how likely the plant is to be found in a wetland habitat. The indicator status of each plant species can be found on the data forms. The different indicator statuses are listed below: - Obligate Wetland (OBL) – highly likely to be in a natural wetland environment - Facultative Wetland (FACW) –most likely to be present in a natural wetland environment - Facultative (FAC) – can be present in both a natural wetland and non- wetland environment - Facultative Upland (FACU) –may be present in a natural wetland, but most likely to be seen in non-wetland conditions - Obligate Upland (UPL) – most likley to occur in non-wetland conditions - No Indicator – the plant does not have enough data to determine the indicator status yet The site is primarily vegetated with Douglas Fir, Yard grass mixtures and Blackberries species throughout the upper edge of the pond. The pond has a variety of wetland vegetation such as cattails, lily pads, spirea and willows. The surrounding area are vegetated with field grass mixtures and Douglas Firs. Soils: The site is mapped as Alderwood Gravelly Sandy Loam Series according to the U.S.D.A Natural Resources Conservation Service Soil Survey of Pierce County, Washington (1979). The series is not listed on the hydric soils list produced by the U.S.D.A Natural Resources Conservation. The NRCS describes the Alderwood Gravelly Sandy Loam as moderately well drained soil located on glacial till plains. In a representative profile, the surface 5 Job Number: 2015-039 Client Name: Ellingson, Arnie layer is about 6 inches thick and is very dark brown gravelly sandy loam. The following layer is about 9 inches thick and is dark brown gravelly sandy loam. The next layer is dark brown very gravelly sandy loam about 15 inches thick. The next layer is a weakly cemented hardpan that is at a depth of about 30 inches. The hardpan is strongly compacted and crushes to very gravelly loamy sand. The depth of the hardpan is between 20 to 40 inches. The soil appeared to be well drained and no indications of ponding or of the soil being hydric were present on the site outside of the depression. Hydrology: The site appears to be well drained and did not show any signs of ponding on the site, except for pond area where it was fed by storm water from the existing highway and surrounding upland areas. The surrounding sites were reviewed for indicators of hydrology and no areas of hydrology were noted. Wildlife: The area is shown on the Priority Habitat Species Map produced by Fish and Wildlife to have critical habitat; however, it is the storm water pond on the site. The trees and depressional pond area do provide great habitat for nesting for birds and habitat for other mammals like squirrels. Topography: The topography at the site has a gentle slope to the pond. Surrounding Wetlands and Impacts: The National Wetlands Inventory (NWI) map did not depict mapped wetlands within the area. It needs to be noted that the NWI maps and GeoData Center needs to be used cautiously as they compile general wetland data. Environmental Design did find wetland habitat located on the site; although it appears to be man made it does meet the criteria of wetland habitat. Environmental Design conducted a further site investigation covering an area of 300 feet or more by site visit and by the use of mapping resources to determine if wetlands were present around the site or if buffers from other wetland habitats would impact the site. For this report the wetland on the site has been named Wetland A. Wetland A has been rated in accordance with the current Department of Ecology's Rating forms and it calculated to be a Category III wetland. Wetland A has a protective buffer of 80 feet as stated in the City of Federal Way's Critical Area Ordinance 19.145.420(2) Table 1. 6 Job Number: 2015-039 Client Name: Ellingson, Arnie Conclusions: Environmental Design, LLC concludes that wetland habitat is present on the site and needs to meet the current code setbacks. The wetland has a buffer of 80 feet in compliance with the City of Federal Way's code. The client has disturbed a portion of the wetland and buffer and will be working in every effort possible to restore the habitat per the mitigation plan set out in this report. The disturbance has been currently stabilized through the use of erosion control techniques in order to keep the site from further damaging the wetland area. The client will conduct removal of the berm, planting and re- grading of the site will take place in the spring of 2018. 7 Job Number: 2015-039 Client Name: Ellingson, Arnie References: Environmental Laboratory. 1987.

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 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.

ALTMANN, PRINCIPAL Ecologist, Project Manager Wetland Delineations, Stream Studies, Functional Analysis, Mitigation, Environmental Impact Assessments, Planning, Regulatory Analysis & Permitting, Wildlife Studies EXPERIENCE Mr. Altmann has 34 years of experience working in resource and environmental planning, project management, and field analysis. His main area of concentration is wetlands and streams and his experience includes: delineations; environmental assessments; impact statements; mitigation plans; natural resource inventories and sensitivity analyses; site planning; and wildlife habitat management studies in Washington, Oregon, Idaho, Alaska, California, Wyoming, New Jersey, New York, and Pennsylvania. REPRESENTATIVE PROJECTS Responsible for over 3,800 wetland and wildlife studies conducted in past 34 years, with most of these projects occurring in King, Snohomish, Skagit, Whatcom, Pierce, Thurston, Clark, Lewis, Kitsap, and Mason counties in Washington State. Most of these projects involved analysis of wetland and stream conditions in relation to some proposed construction activity that could potentially affect their functions and values. Many of the studies involved delineation only, whereas others required determination of wetland functions and values and wetland impact mitigation planning and other sensitive areas analyses. Project sizes ranged from under 1 acre to over 600 acres, with the wetlands on these properties being nearly as variable as their size. Wildlife studies include flora and fauna inventories, habitat impact assessments, and threatened and endangered species studies. Some of the projects representative of this experience are listed below. Shoreline Delineation & Habitat Assessment for private land owners on Lake Sammamish, Bellevue, WA Wetland Mitigation and Long-Term Monitoring for Weyerhaeuser Real Estate Development Company’s Mint Farm Phase II project in the City of Longview, WA Stream Delineation Study, Mitigation Plan for the Greystone PRD, Redmond, WA Wetland Delineation and Study for the Group Health Support Facility in the City of Tukwila, WA Critical Areas Delineation, Study, and Mitigation Plan for the Cadman High Rock Quarry in Snohomish County, WA Critical Areas Delineations, Studies, and Mitigation Plans for the Microsoft Corporate Campus in the City of Redmond, WA Critical Areas Study, Mitigation Plan, Biological Assessment, and Long-Term Monitoring on 90-acre Northpointe Corporate Campus for OPUS NW in Snohomish County, WA Wetland Delineation, Study, and Mitigation Plan for the Puyallup Downs Residential Development in the City of Puyallup, WA Wildlife Study on 40-acre Site in North Bend Area of King County, WA for Private Developer Critical Areas Delineation and Study for Data I/O Corporation in Redmond, WA for the Quadrant Corporation Sensitive Areas Assessment for 74-acre Church site in Redmond, King County, WA Wetland Delineation on 47-acre Marine Industrial Site Location in Snohomish River Estuary, Everett, Snohomish County, WA for Private Developer Wetland Study and Mitigation Plan for 37-acre Office Park Site in Redmond, King County, WA for Private Developer Wetland Maintenance and Monitoring Plan for Property on Raging River in King County, WA for Private Developer OTHER PROJECT EXPERIENCE • Wetland Biologist for the King County Parks, Planning and Resource Department, Environmental Division, Resource Planning Section.
