Addition of this portable will not alter the existing use of the site, which is a public school. The proposed portable will add additional instructional space. The portable will have electricity, but no water or sewer service. The portable will not be used for science labs, art studios, or other instructional types that would require running water. The intention is to place the new double classroom portable this summer south-east of the existing school, with opening in October. The portable will be 1,792 square feet in size, single story, and not fire sprinklered. The portable will have metal stairs and ramps that will be connected to the existing school by a paved path. The Type of Construction per the 2012 IBC will be VB. Occupancy Classification per the 2012 IBC will be Classification Group E. The ITE Land Use Code is 520 — Elementary School. The total lot area is 485,710 square feet. The existing building area is 45,145 square feet and 1,792 square feet of portable will be added. This project will meet the following Federal Way Development Standards: SEPA The proposed improvements are exempt from SEPA. Required Yards and Lot Coverage The proposed portable meets the 50-foot front and 20-foot side and rear setback requirements for schools in the OP zone. No maximum lot coverage applies and the project meets buildable area requirements. Maximum Building Height The proposed portable will be under the maximum building height in the OP zone of 35 feet. See the elevation plans. Required Parking The parking requirements for elementary schools in the OP zone use chart are one parking stall for each employee. The number of current employees at the school is 42 and 2 new employees associated with the new portable will be added to the staff at the school. With the addition of the new double classroom portable, 44 parking stalls will be required. There are 78 existing parking stalls on the site and no new parking stalls will be provided. Landscaping The existing landscaping meets current code requirements for perimeter landscaping per FWMC 19.125.060. No additional landscape planting is required with the proposed addition of a portable at this site. ilro Tree Retention Requirements No trees are anticipated to be removed as part of the project on or near the portable classroom site. If existing nearby trees and their roots may be impacted by the project, the following regulations will be followed to protect them: 19.120.160 Tree and vegetation protection during construction. (1) No clearing shall be allowed on a proposed development site until the tree retention and landscape plans have been approved by the city of Federal Way. (2) A no disturbance area shall be established for each tree to be protected. The no disturbance zone shall be equal to the critical root zone which is defined as 12 inches radius for every one inch of tree diameter measured at four and one-half feet above ground. Any other no disturbance area proposed by the applicant shall be determined by a qualified arborist and subject to review and approval by the director. (3) The no disturbance zone shall be identified during the construction stage with: (a) A temporary five-foot chain -link fence; and (b) Tree protection signage attached to the fence which reads "TREE PROTECTION FENCE — No soil disturbance, parking, storage, dumping, or burning of materials is allowed within the Tree Protection Fence." (4) No soil disturbance, parking, storage, dumping, burning of materials, impervious surfaces, fill, excavation, or storage of construction materials shall be permitted within the no disturbance area. (5) If the grade level around the tree is to be raised by more than one foot, a rock well shall be constructed. The inside diameter of the rock well shall be equal to the diameter of the tree trunk plus 10 feet. Proper drainage, and irrigation if necessary, shall be provided in all rock wells. (6) The grade level shall not be lowered within the larger of the drip line of the tree(s) or the critical root zone of the tree(s). (7) No trenching is allowed in any critical tree root zone areas. (8) No installation of any impervious surfaces is allowed in critical root zones. Where road or sidewalk surfaces are needed within critical root zones, unmortared porous pavers or flagstone (rather than concrete or asphalt) may be used. Boardwalks or bridging may span root zones without harming the tree roots. (9) Tree protection areas (i.e., critical root zone) must be prepared to better withstand the stresses of the construction phase by, if necessary, fertilizing, pruning, and mulching around them well in advance of beginning any construction activities. (10) Alternative protection methods may be used if accepted by the director to provide equal or greater tree protection. (11) Encroachment into the no disturbance area may be allowed where the director determines encroachment would not be detrimental to the health of the tree. Project Memo Page 2 of 3 Q©180 Panther Lake ES Portable 2150238.30 June 29, 2015 Community Design Guidelines ■ The roof design shall utilize forms and materials that avoid the general appearance of a "flat" roof. Pedestrian connections to the main building and existing pedestrian networks will be provided. • A completed Crime Prevention through Environmental Design (CPTED) checklist has been submittal as part of the Process I application. Statement of Architectural Design Intent The proposed project will add one double -classroom portable building at Panther Lake Elementary School. The portable will be of standard construction. The roofing material will be asphalt shingle, of a black -to -dark gray color. Siding will be durable plywood surfaced with hardboard, with 8-inch grooves, and of a color designed to blend with and complement the color of Panther Lake Elementary School's main building. The skirting surrounding the portable's foundation will be plywood painted to match the siding. Trim, around windows and at the building corners, will be clear cedar with a coloring to complement the siding. The proposed portable will be of similar design as the previously permitted portable for the Panther Lake Elementary School (see submitted elevation plans and color and materials indicator).

DUSEK Assessment, Management and Regulatory Permitting June 26, 2015 Federal Way School District c/o AHBL 2215 North 30th Street, Suite 300 Tacoma WA 98403 RE: Panther Lake Elementary School Wetland Delineation 128 Rainbow Lane Packwood, WA, 98361 (253)861-3355 At your request I have reviewed (a) the site and area within 200 feet of a proposed new modular building for wetland conditions, and (b) the Wetland Delineation Technical Memorandum for Panther Lake Elementary School dated July 18, 2008 prepared by Otak. The site is located at 34424 1" Avenue South, Federal Way, Washington and the proposed modular building is located in the east central portion of the site (see attached AHBL Site Plan). We understand that the City of Federal Way has requested an update to the 2008 wetland delineation. The original 2008 Otak Wetland Delineation Technical Memorandum generally represents the current site conditions. Wetland A was determined by Otak and confirmed by the City of Federal Way to be a 1,406 square foot, Category I1, non jurisdictional wetland because it was less than 2,500 square feet in size in accordance with Federal Way City Code (FWCC) 22-1357(a)(2). A summary of the site conditions and findings on June 24, 2015 including vegetation, soils and hydrologic conditions within 200 feet of the proposed portable building based on the Western Mountains, Valleys, and Coast Regional Supplement to the 1987 Corps of Engineers Wetland Delineation Manual (which was an update to the 1997 Washington State Wetlands Identification and Delineation Manual in WAC 173.22) follows. 1. Wetland flags from 2008 were still present. 2. Wetland Flag 5 is no longer accurate as the wetland has extended 5 feet to the west (see attached redlined Figure 4 from the 2008 Otak report). 3. The proposed modular building at its nearest point is 100 feet from the wetland. 4. All other wetland boundary flags were still accurate. 5. Other wetlands are not located on or within 200 feet of the project site. 6. The wetland was determined to have increased by 112 square feet for a total size in June 2015 of 1,518 square feet. 7. The wetland in June 2015 is still a Category II, non jurisdictional wetland because it does not exhibit Category I wetland characteristics, it is less than 2,500 square feet in size, is less than one acre in size in its entirety and has two or more wetland classes, with neither class dominated by nonnative invasive species in accordance with FWCC 15.10.250. 8. Non jurisdictional wetlands do not require buffers in Federal Way under the current code. JUN 2 9.2015 CITY OF FEDERAL WAY CDS H-2015-06 Vegetation The wetland is a Palustrine scrub -shrub, emergent system. Trees are not rooted in the wetland but provide approximately 50% cover to the wetland system. The scrub -shrub plant community is dominated by crabapple, salmonberry, and Douglas spiraea. The emergent community is dominated by slough sedge and buttercup. The expanded wetland area near Wetland Flag 5 is dominated by slough sedge (see attached photograph). Some high points in the wetland contain sword fern. Trees surrounding the wetland that provide shade to the wetland include Douglas fir, big leaf maple, red alder, black cottonwood and western red cedar. The forest understory ;is dominated by salal, oceanspray, Indian plum, sword fern, bracken fern, Oregon grape, Himalayan blackberry and evergreen blackberry. West of the wetland is a mowed, and maintained grassy recreational field. Hydrologic Conditions The wetland is in a depression with a human constructed swale located in the southeast portion of the wetland. Evidence of flowing water was not present in the swale area; therefore, the 2008 conclusion would be correct that the Swale is not functioning as a stream but may provide overflow from the wetland in years of very high rain fall. A permitted storm outfall from the school is located approximately 50 feet north of the wetland (see the attached AHBL Site Plan). Saturated soils and surface inundation were not present during the site visit but indicators of winter and spring hydrologic conditions were present including water marks and surface soils cracks, and the wetland was known to contain saturated soils and inundation in 2008. 2015 is a drought year but has not impacted the wetland determination made in this report. Soils The wetland depression contains hydric soils including a black (10YR2/1) sandy clay without redoximorphic features (2015 Data Plot 1). SoiIs in the swale portion of the wetland included dark brown (10YR 31) silt loam without redoximorphic features (2015 Data Plot 2). Soils in the upland portion of the site west of the wetland included 1 OYR 4/4 gravelly features (2015 Data Plot 3). sandyy loam without redoximorphic In summary, the wetland is a Category II, non jurisdictional system in accordance with FWCC 15.10.250 and does not require a buffer.

In addition to the parcel with the existing school building (school parcel), the School District also owns the undeveloped triangular -shaped parcel to the north (north parcel) (see Figure 1). To minimize disruptions for the students, the new school building will be constructed in the north parcel while classes are held in the existing school building. Once the new building is operational, the south parcel will be reconstructed, and will consist mainly of parking and play areas, as well as a small portion of the new school building. The parcel east of the school parcel (east parcel) is owned by St. Francis Community Hospital, and is currently undeveloped. Critical areas located on the east parcel will affect the placement of the new school building if the buffers extend onto either the school parcel or the north parcel. All three parcels are located within the city limits of Federal Way. Findings Otak biologists conducted a field reconnaissance on January 23 and 24, 2008 to assess all three parcels for the presence of wetlands and streams. No wetlands or streams were identified on either the school parcel or the north parcel. Two wetlands were identified on the hospital -owned parcel to the east. During the site visit, Otak staff characterized the site and assessed each of the three parcels (school, north, and east parcels) for the presence of wetlands and streams. The east parcel was not evaluated in its entirety - only the western side of the parcel within 150 feet of school parcel was assessed. The school and north parcels front V Avenue South to the west (see Figure 1 site map). A King County Library branch is located north of the north parcel, and an apartment complex is located south of K:\project\31100\31147E\Reports\31147E Wedand Tech Memo sla.doc Greene Gasaway Architects Page 2 Panther Lake Elementary School February 5, 2008 the school parcel. As previously mentioned, an undeveloped parcel owned by the hospital is located east of the school parcel. Below are our findings for each of the three parcels. School Parcel The parcel that the school is currently situated on is approximately 8.9 acres (Parcel #2021049110). The school building and parking area occupy most of the western half of the parcel, and play fields occupy most of the eastern half. The play fields are a mixture of sand/dirt fields, mowed lawn, and paved areas for playground equipment (see photographs at the end of the text). The parcel slopes gradually to the east. Between the school and the lower play fields, a section of slope is forested by Douglas fir (Pseudotsuga men�iesh). Between the parking lot and the sidewalk that fronts 1" Avenue South there is a forested area that is comprised of native upland plant species, including Douglas fir, madrone (Arbutus men!Ziesh), Western red cedar (Thuja plicata), salal (Gaultheria shallop) and bracken fern (Pteridium aquilinum). West of the forested area is mowed lawn. No wetlands or streams were identified on this parcel. North Parcel The parcel located directly north of the existing school is the proposed site for the new school building (Parcel #2021049182). This parcel, also owned by the school district, is approximately 2.25 acres and is currently undeveloped. The parcel is generally flat along the north and west edges and gently sloping towards the south and southeast. To the north/northeast of the parcel is a King County Library branch, and a stormwater pond that appears to receive runoff from the library parking lot. The north parcel is covered by second growth forest dominated by Douglas fir and red alder (Alnus rubra). The shrub layer is a nearly solid carpet of salal. Other common species include cedar, madrone, salmonberry (Rebus spectabilis), Indian plum (Oemleria cerasiformis), ocean -spray (Holodiscus discolor), beaked hazelnut (Corylus cornuta), and sword fern (Polystichum munitum). There are two areas on this parcel that appear to have wedand characteristics. One suspect area is a depression near the south central portion of the parcel. The area is dominated by black cottonwood (Populus balsamifera) and red alder in the canopy, and the shrub layer is dominated by salmonberry and spirea (Spiraea douglash), with some Nootka rose (Rosa nutkana). The depression is devoid of an herbaceous layer. There is a very distinct break in the vegetative community around the edge of the depression where the salal starts. A soil pit was dug at the lowest topographic point in the area to determine whether wetland hydrology and hydric soil were present (see Data Sheet 1). The soil was barely damp down to a depth of eighteen inches. Wetland hydrology was not present even though the test pit was dug during the rainy season. Although the upper nine inches of the soil was black (10YR 2/1), below that the soil matrix was bright (10YR 5/3). Even though redoximorphic features were present, with a matrix chroma of 3, the soil below the A horizon did not satisfy the criteria for a hydric soil. Because the small patch of hydrophytic vegetation lacks wetland hydrology and hydric soil, it does not satisfy the criteria for a wetland. K\project\31100\31147E\Reports\31147E Wetland Tech Memo sla.doc Greene Gasaway Architects Page 3 Panther Lake Elementary School February 5, 2008 The second area that presented wetland characteristics is located in the southeast corner of the parcel in a topographically low area, with a very gradual slope to the east. Two pipes from the stormwater pond on the adjacent library parcel appear to outlet into the area. At the time of the site visit, there was no standing water in the storm pond. The forested community is dominated by black cottonwood and alder, with salmonberry in the understory. There are only occasional trailing blackberry vines (Rubes ursinus) in the herbaceous layer. A soil pit was dug to determine whether wetland hydrology and hydric soil were present (see Data Sheet 2). There were pockets of saturated soil from the surface down to 12 inches. Below 12 inches, the soil was only moist, and there was no standing water at the bottom of the soil pit. Based on the presence of saturated soil, we concluded that wetland hydrology was present. The upper six inches of the soil was gravelly sandy loam (10YR 3/3). Below that to 17 inches was gravelly loamy sand (10YR 4/3) with some cobbles. No redoximorphic features were observed. With a matrix chroma of 3, the soil does not have hydric soil indicators. It appears that when the stormwater pond was built, this area may have been graded and filled as evidenced by the gravel, cobbles, and sand in the soil pit. Because this area lacks hydric soil, it does not meet the criteria for a wetland. No other wetlands or streams were identified on the parcel. Offsite East Parcel As mentioned previously, the offsite parcel to the east is undeveloped and is owned by St. Francis Hospital. The western half of the east parcel is forested by a mixture of second -growth evergreen and deciduous species. East of the school fence, the land slopes gently down towards the east. The forested area along the southeast side of the school fence is dominated by Douglas firs, with some alders and big -leaf maples (Acer macrophyllum). A few cedars and Western hemlocks (Tsuga heterophylla) are located near the southeast corner of the school parcel. The forest understory consists of a. thigh - high carpet of salal, with scattered ocean -spray, Indian plum, sword fern, and tall Oregon grape (Mahonia aquifolia). Where the canopy is thinner, there is some trailing blackberry and bracken fern among the salal. Further downslope to the east, the forest transitions into an alder -dominated canopy with salmonberry and scattered Indian plum and sword fern in the understory. Wetlands We identified two wetlands on the east parcel. See Figure 1 for approximate locations. A section of a large wetland is located near the northeast corner of the school property, and a small wetland is located near the eastern center of the school property. We referenced the approximate locations of the wetlands to the chain -link fence that runs along the eastern boundary of the school parcel. Despite the date of the site visits Qanuary 23 and 24, 2008), the visits occurred during the growing season. We observed expanding catkins and leaf buds on alders and beaked hazelnut; and expanding leaf buds on Indian plum, spirea, red -osier dogwood (Cornus sericea), cascara (Bhamnus purshiana), salmonberry, and ocean -spray. K:\project\31100\31147E\Reports\31147E Wetland Tech Memo sla.doc Greene Gasaway Architects Page 4 Panther Lake Elementary School February 5, 2008 Large Wetland: We identified a wetland area located approximately 40 feet east of the school fence, near the northeast corner of the school playground. This wetland area is part of a larger wetland. We assume that it is wetland 20-21-4-121 mapped by the Federal Way Wetland Inventory (FWWI) on the eastern parcel (see Figure 2). Due to scope limitations, we only investigated the sections of the wetland located within approximately 150 feet of the school parcel. A small extension of the wetland (approximately 40 feet wide) is located within approximately 120 feet of the school parcel. The wetland extension is oriented in a roughly east -west direction. From approximately 120 feet east of the school fence, the wetland continues eastward and expands to the north. In the wetland area that we examined, a scrub -shrub community is surrounded by a forested fringe (see Data Sheet 4). The scrub -shrub community is dominated by salmonberry with scattered lady fern (Athyrium filix femina). The forested fringe is dominated by alders, with some black cottonwood and cascara. The wetland area exhibited both hydric soil and wetland hydrology. The soil in the wetland was predominately very dark grayish brown (10YR 3/2) clayey sand with mottles below. 6 inches of the surface (see Data Sheet 4). The soil was saturated at 8 inches, and there was standing water 14 inches below the surface. The primary source of hydrology for the wetland is likely to be surface runoff directed towards the wetland by surrounding topography. Between the western wetland edge and the school fence to the west, the buffer is dominated by alders, cedars, and cottonwoods with localized salal and salmonberry in the understory. The portion of the wetland buffer located on the school parcel consists of a heavily used playing field. At the time of the site visit there was little to no vegetation on the playing fields. Small Wetland: We identified a small depressional wetland adjacent to the central section of the school parcel. The wetland is roughly oval in shape, and at the closest point, the wetland edge is approximately nine feet east of the school fence. The wetland is predominately palustrine scrub - shrub with emergent patches and a forested fringe (see Data Sheet 3). The scrub -shrub community is dominated by Western crabapple (Malus fusca) with some salmonberry, spirea, and Indian plum. The emergent community is dominated by large patches of slough sedge (Carex obnupta) with a few smaller patches of creeping buttercup (Ranunculus repens) and scattered sword ferns. The wetland is surrounded by a fringe of tall cottonwoods with a few cedars. The wetland had both hydric soil and wetland hydrology. The soil in the wetland was black (10YR 2/1) sandy clay without mottles (see Data Sheet 3). The soil was saturated at five inches, and there was standing water seven inches below the surface. The primary source of hydrology for the wetland is likely to be surface runoff directed towards the wetland by surrounding topography. Although we did not locate any outlet pipes, some drainage from the play fields may be directed towards the wetland. K:\project\31100\31147E\Reports\31147E Wedand Tech Memo sla.doc Greene Gasaway Architects Page 5 Panther Lake Elementary School February 5, 2008 A small swale is located near the southeast corner of the wetland, and it may serve as an outlet for the wetland. The swale is approximately four feet wide and is oriented towards the south-southeast. Because of the regular shape and straight line of the swale, it appears to be man-made. However, there was no surface flow in the swale at the time of the site visit Qanuary), and there was no evidence of previous flow. There were no high water marks or scour marks, and we did not observe any drainage patterns or sediment deposits. At the time of our site visit, there was little or no vegetation in the swale. In the section of the swale located closest to the wetland, the soils either had standing water within two inches of the surface, or the soil was saturated within 12 inches of the surface. At approximately 21 linear feet south-southeast of the wetland, there is a very slight rise in the swale. From that point onward (away from the wetland), the soil in the swale was moist but not saturated. On the basis of hydrology, we included the adjacent 21-foot segment of the swale as part of the wetland. Due to lack of surface flow even during the wet season, the swale does not satisfy the FWCC definition of a stream (FWCC 22-1 Definition: Stream). Using a tape, we measured the approximate size of the wetland. We measured the oval section of the wetland at the widest points, and also measured the wetland section of the swale. The oval section of the wetland is approximately 49 feet (north -south) by 41 feet (east -west). The swale is approximately 21 feet long by 4 feet wide. The total approximate area of the wetland is 2,100 square feet (2,009 + 84 = 2,093). This is likely to be an overestimate of the wetland area, since we calculated a rectangular area, and the wetland is roughly oval -shaped. The buffer in the narrow band between the western edge of the wetland and the school fence is dominated by cottonwoods with some alders. The portion of the wetland buffer located on the school parcel consists of a heavily used playing field. At the time of the site visit there was little to no vegetation on the playing fields. Wetland Ratings and Buffers Large Wetland: Federal Way Wetland Inventory (FWWI) mapped a Category I wetland (20-21-4- 121) in the parcel immediately east of Panther Lake Elementary School (see Figure 2). This wetland is an extension of a large wetland associated with West Hylebos Creek, and as such it is rated as Category I. The majority of wetland 20-21-4-121 is located south of S 348`h Street in West Hylebos Wetlands Park. South 348 h Street divides the wetland, and a culvert under the street provides hydrologic connection between the two wetland sections. According to Daniel Ackerman, PLS, CFedS, of ESM Consulting Engineers, LLC, the elevation of the bottom of the intake culvert on the north side of S 348 h Street is 217.4 feet, and the elevation of the outflow on the south side is 215.55 feet. Guidance from Washington State Department of Ecology, which is based upon best available science, specifies that a wetland should be rated as two separate units when it is divided by a human - made feature that prevents water from flowing equally well between the two areas. Specifically, wetlands should be rated separately when "the high -seater marks on either side der by more than 6 inches in K\project\31100\31147E\Reports\31147E Wedand Tech Memo sla.doc Greene Gasaway Architects Page 6 Panther Lake Elementary School February 5, 2008 elevation" (page 19, Washington State Wetland Rating System for Western Washington, Revised, August 2004, Ecology Publication #04-06-025). Because the elevation difference between the inlet and outlet ends of the culvert is greater than 22 inches, we conclude that the sections of wetland 20- 21-4-121 located on the north and south sides of S 348t1i Street should be rated as separate units. Scope limitations did not permit a reconnaissance of the entire portion of wetland 20-21-4-121 located north of S 348`h Street. However, based on our observations of the wetland sections located near Panther Lake Elementary School and in the vicinity of the inlet culvert on the north side of S 348d' Street, we conclude that the wetland should be rated as Category II according to Federal Way City Code [FWCC 22-1357(a)(1 and 2)]. The portion of wetland 20-21-4-121 located north of S 348`' Street does not satisfy the criteria for a Category I wetland: it does not contain listed species or habitat; it does not provide irreplaceable ecological functions, and it does not contain open water. It does satisfy the criteria for a Category II wetland: it is greater than one acre in size, and it has at least two wetland vegetative classes (forested and scrub -shrub) that are not dominated by non-native invasive species. Category II wetlands receive 100-foot buffers [FWCC 22-1357 (b) (2)]. Small Wetland: The small wetland does not satisfy the criteria for a Category I wetland: it does not contain listed species or habitat; it does not provide irreplaceable ecological functions, and it does not contain open water [FWCC 22-1357 (a) (1)]. Although we did not do a formal delineation, based on our field measurements, the wetland is approximately 2,100 square feet. In order to be jurisdictional by the City of Federal Way as either a Category II or III wetland, the wetland has to be greater than 2,500 square feet [FWCC 22-1357(a)(2 and 3)]. However, if the wetland is greater than 2,500 square feet, it would satisfy the criteria for a Category II wetland: it would be less than one acre in size with two or more wetland vegetative classes (scrub -shrub, emergent and forested) that are not dominated by non-native invasive species. Category II wetlands receive 100-foot buffers [FWCC 22-1357(b)(2)]. If the wetland is less than 2,500 square feet, no buffer is required by Federal Way City Code [FWCC 22-1357(a)(2 and 3)]. Potential Project Impacts Because there are no wetlands located on either the school parcel or the north parcel, there will be no direct impacts to wetlands by the project. Project designs are still being developed, but to the extent possible, the project will avoid and/or minimize impacts to buffers of the wetland(s) located on the adjoining parcel. Assuming that the small wetland is greater than 2,500 square feet, it is unlikely that there will be any impacts to its buffer. The onsite section of the buffer will most likely continue to be used as a play field. Constraints of constructing a new school building while keeping the current building open for classes may necessitate some impacts to the buffer of wetland 20-21-4- 121. The majority of the onsite portion of that buffer consists of a play field. Under Federal Way City Code, Panther Lake Elementary School is defined as a Class II essential public facility [FWCC Chapter 22-1 Definitions: Essential public facility (4) bAi]. Intrusions into wetland buffers by essential public facilities are allowed by City code, providing that the Director of Community K:\project\31100\31147E\Reports\31147E Wed -and Tech Memo sla.doc Greene Gasaway Architects Page 7 Panther Lake Elementary School February 5, 2008 Development determines that the intrusion is necessary and constitutes the minimum possible impact. FWCC 22-1359 (c) specifies: "The darector of community development may permit theplacement of an essentialpublic facility, public utility or otherpublic improvements in d regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists based on an analysis of technology and ystemciency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the regsrirements of the public facility or utility." FWCC does not specifically require mitigation for buffer impacts by essential public facilities [FWCC 22-1359 (c)]. However, it may be possible to provide some enhancement plantings in areas where buffers are reduced. Conclusions No wetlands or streams were identified on the two parcels where construction of the new elementary school is proposed (school and north parcels). Two wetlands (small and large) were identified on the parcel located to the east of the school parcel (east parcel). If the small wetland is greater than 2,500 square feet, it is rated as a Category II wetland [FWCC 22-1357(a)(2)] with a 100- foot buffer [FWCC 22-1357 (b) (2)]. A portion of this buffer extends onto the school parcel. If the wetland is smaller than 2,500 square feet, it receives no buffer per Federal Way City Code [FWCC 22-1357(a)(2 and 3)]. The large wetland is assumed to be part of wetland 20-21-4-121 listed by the Federal Way Wetland Inventory as a Category I wetland. Because S 348"' Street divides the wetland and prevents water from flowing equally well between -the north and south sections, the two sections were rated as separate units according to guidance from Washington State Department of Ecology. The northern portion of wetland 20-21-4-121 (located in the east parcel) is rated as a Category II wetland [FWCC 22-1357(a)(2)] with a 100-foot buffer [FWCC 22-1357(b)(2)]. A portion of this buffer extends onto the school parcel. Because Panther Lake Elementary School is an essential public facility [FWCC Chapter 22-1 Definitions: Essential public facility (4) bAi], the Director of Community Development may allow necessary intrusions into the wetland buffers [FWCC 22-1359 (c)]- If you have any questions regarding our findings, please contact us at (425) 822-4446.

Background Panther Lake Elementary School is located at 34424 VY Avenue South in the City of Federal,Way. In addition to the parcel with the existing school building (school parcel), Federal Way School District also owns the undeveloped triangular -shaped parcel to the north (north parcel) (see Figure 1). The School District is proposing to construct a new school building. To minimize disruptions for the students, the new building will be constructed on the north parcel while classes are held in the existing school building. Once the new building is operational, the school parcel will be reconstructed, and will ultimately contain parking facilities and play areas, as well as a small portion of the new school building. The parcel located to the east of the school parcel is owned by St. Francis Community Hospital (hospital parcel), and it is currently undeveloped. All three parcels are located within the city limits of Federal Way. Site photos are located in Appendix A. K:\project\31100\31147E\Reports\Wetland Delineation Memo\31147E Wetland A Delineation Memo final.doc Green GasawayArchitects Page 2 Panther Lake Elementary School.- Delineation of Offsite Vetland A July 18, 2008 During previous reconnaissance visits to the three parcels Qanuary 23 and 24, 2008), Otak staff determined that no wetlands or streams are located on either the school parcel or the north parcel (215108 Otak reconnaissance memo). This finding was confirmed by the City's biologist (517108 ESA Adolfson memo). During the January reconnaissance visit, Otak staff evaluated only the portion of the hospital parcel located within approximately 200 feet of school parcel. Otak identified two wetlands (one large and one small) on the hospital parcel (215108 Otak reconnaissance memo). The large wetland is Wetland 20-21-4-121 (Federal Way Wetland Inventory), and the City's biologist confirmed that it is located further than 200 feet from the eastern edge of the school parcel (517108 ESA Adolfson memo). At its closest point, the small wetland (Wetland A) is located within approximately nine feet of the school fence. As a result, if Wetland A was jurisdictional, its buffer would extend onto the school parcel. At the request of City staff (5113108 Federal Way memo), Green Gasaway Architects asked Otak staff to delineate Wedand A so that its boundaries could be surveyed to determine whether it is larger than 2,500 square feet, and thus jurisdictional under Federal Way City Code [FWCC 22-1357(a)(2)]. On May 23, 2008 Otak staff conducted a delineation of Wetland A, and this technical memorandum presents our findings.

The western half of the hospital parcel is forested by a mixture of second - growth evergreen and deciduous species. East of the school fence, the land slopes gently down towards the east. The forested area along the southeast side of the school fence is dominated by Douglas firs (Pseudotsuga men#esiz), with some alders (Alnus rubra) and big -leaf maples (Acer macrophyllum). A few cedars (Thuja plicata) and Western hemlocks (Tsuga beterophylla) are located near the northeast corner of the school parcel. The forest understory consists of a thigh -high carpet of salal (Gaultheria shallop), with scattered ocean -spray (Holodiscus discolor), Indian plum (Oemleria cerasiformis), sword fern (Polystichum munitum), and tall Oregon grape (Mahonia aquifolia). Where the canopy is thinner, there is some trailing blackberry (Rubus ursinus) and bracken fern (Pteridium aquilinum) among the salal. Further downslope to the east, the forest transitions into an alder - dominated canopy with salmonberry (Rubus spectabilis) and scattered Indian plum and sword fern in the understory. Wetland 'A As mentioned above, during the January site visits, Otak staff identified a small depressional wetland (Wetland A) on the hospital parcel, adjacent to the central section of the school parcel (215108 Otak reconnaissance memo). Subsequently, the City's biologist confirmed the presence of Wetland A (517108 ESAAdolfson memo). Wetland A is roughly oval in shape, and at the closest point, the wetland edge is approximately nine feet east of the school fence. A small swale is located near the southeast corner of Wetland A (see Survey Maps in Appendix C). Methodology On May 23, 2008, Otak staff delineated Wetland A with sequentially numbered flags. As required by FWCC (22-1 Definitions: Regulated Wetlands), we delineated Wetland A according to the Routine Methodology in the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology, 1997). The wetland was assessed for the three parameters that determine a wetland: hydrology, hydrophytic vegetation, and hydric soils. Data sheets are included in Appendix B. The wetland flags were professionally surveyed by ESM (see Appendix C). Data sheets are located in Appendix B. Vegetation The wetland vegetation is predominately Palustrine Scrub -Shrub with Emergent patches and a fringe of scattered trees. The scrub -shrub community is dominated by Western crabapple (Males fusca) with some salmonberry, spirea (Spirea douglash), and Indian plum. The emergent community is dominated by large patches of slough sedge (Carex obnupta) with a few smaller patches of creeping buttercup (Ranunculus repens) and scattered sword ferns. The wetland is surrounded by a scattered fringe of tall K:\project\31100\31147E\Reports\Wetland Delineation Memo\31147E Wetland A Delineation Memo final.doc ,�) Green GasawayArchitects 5 Panther Lake Elementary School.• Delineation of O frite Wetland A July 18, 2008 cottonwoods (Po ulus balsamifera) with a few cedars. Many of the trees that shade Wetland A are rooted outside of the wetland. As a result, the wetland does not have a forested class. Hydrology Wetland hydrology was present in Wetland A. During the January site visit, the soil was saturated to the surface in some areas, and in other areas it was saturated to five inches below the surface with standing water two inches below that (see Data Sheet 3). The January site visit occurred during the growing season. We observed expanding catkins and leaf buds on alders and beaked hazelnut (Corylus cornuta); and expanding leaf buds on Indian plum, spirea, red -osier dogwood (Cornus sericea), cascara (Rhamnus purshiana), salmonberry, and ocean -spray. Although the wetland soil was only moist during the May visit, we observed oxidized root channels as hydrology indicators (see Data Sheets 7 and 9). The primary source of hydrology for Wetland A is likely to be surface runoff directed towards it by the surrounding topography. Although we did not locate any outlet pipes, some drainage from the play fields may be directed towards Wetland A. A small swale is located near the southeast corner of Wetland A, and it may serve as an outlet for the wetland. The swale is approximately four feet wide and is oriented towards the south-southeast. Because of the regular shape and straight line of the swale, it appears to be man-made. However, there was no surface flow in the swale during either the January or May site visits, and there was no evidence of previous flow. There were no high water marks or scour marks, and we did not observe any drainage patterns or sediment deposits. There was little or no vegetation in the swale during either site visit. In the section of the swale closest to the main (depression) portion of the wetland, during the January visit the soils either had standing water within two inches of the surface or the soil was saturated within 12 inches of the surface. At approximately 15 linear feet south-southeast of the main (depression) portion of the wetland, there is a very slight rise in the swale. From that point onward (away from the wetland), the soil in the swale was moist but not saturated during the January visit. On the basis of hydrology, we included only the adjacent 15-foot segment of the swale as part of the wetland. Due to lack of surface flow even during the wet season, the swale does not satisfy the FWCC definition of a stream (FWCC 22-1 Definition: Stream). Soils Hydric soils are present in Wetland A. The soil in the main (depression) portion of the wetland was black (10YR 2/1) sandy clay without mottles (see Data Sheet 3). The soil in the portion of the swale that satisfies wetland criteria was dark brown (2.5Y 5/2) silt loam with redoximorphic features (see Data Sheet 9). Wetland Rating and Regulatory Issues The City's biologist confirmed Otak's finding that if Wetland A were jurisdictional, it would satisfy the criteria for a Category II wetland [FWCC 22-1357(a)(2)] (5/7108 ESAA.dolfson memo and 2/5/08 Otak reconnaissance memo). The survey determined that Wetland A is 1,406 square feet in size (see K:\project\31100\31147E\Reports\Wetland Delineation Memo\31147E Wetland A Delineation Memo final.doc Green GasawayArcAitects Panther Lake Elementary School. Delineation of Offsite Wetland A July 18, 2008 Appendix C). Because Wetland A is smaller than 2,500 square feet, it is not jurisdictional by the City of Federal Way [FWCC 22-1357(a)(2)]. Federal Way City Code specifies `Although a site- pecifzc wetland may not meet the criteria described above, it will be considered a regulated wetland if it is functionally related to another wetland that meets the Criteria' (FWCC 22-1 Definitions: Regulated Wetlands). Based on observations made during site visits by Otak staff in January and May 2008, it is our conclusion that Wetland A is not functionally related to Wetland 20-21-4-121 (6125108 Otak memo). Wetland A is located more than 150 feet away from Wetland 20- 21-4-121, and we did not see any evidence of a surface connection between the two wetlands. The defined section of the swale located near the southeast corner of Wetland A does not extend much further than approximately 60 feet south-southeast from the wetland. At that point the swale loses definition and becomes indistinguishable from the surrounding upland. Even in January, we did not observe any surface flow in the defined swale, and there was no evidence of previous flow. Conclusions Otak staff delineated Wetland A on the hospital parcel, and the survey determined that Wetland A is 1,406 square feet in size. Because Wetland A is smaller than 2,500 square feet and is not functionally related to any other wetland, it is not jurisdictional by the City of Federal Way [FWCC 22- 1357(a) (2)].
