A review of the material you submitted indicates the following issues that must be addressed prior to building permit approval. GEOTECHNICAL"REPORT The subject property is in an area identified as being geologically hazardous (landslide hazard area with 40 percent slope). Please submit any current geotechnical reports that address the criteria established in Federal Way Revised Code (FWRC) 19.145.240(2) and (3). The report should address what types of geologically hazardous areas exist; impacts to the slope and adjacent properties that may result from the construction activity; and measures to avoid or mitigate those impacts. Also, the report should evaluate the adequacy of the proposed erosion/sedimentation control measures (silt fencing) for this development. The city may choose to utilize our third party geotechnical engineering firm to review the report submitted by your geotechnical engineer. If so, the cost of this review would be at the applicant's expense. REGULATED STREAM/ CRITICALAREAS Be aware that construction staging and equipment cannot be located in any stream or geologically hazardous area buffer area. In order to stay out of the buffer, the improvements may have to be reduced or moved to adequately provide room for excavation, foundation, and/or general maneuvering around the building. A construction fence/physical barrier is required during construction to prevent disturbance to the wetland buffer. The construction fence must be located outside the buffer so when digging and setting the silt fence, the buffer will not be impacted. Please depict the fence location on the site plan. + Prior to approval of the building permit, the city will prepare and record, with the King County Recorder's _Office at the expense of the applicant a restrictive covenant against tT7e property, The cove a��ygll_mte_ that no land surface modification may take place and no structure or improvement may be located in the geologically hazardous area, or other critical area buffers.

The site is located at 105 SW 292nd Streetln'the Redondo area of Federal Way, Washington. The general location of the site is shown on the attached Site Vicinity Map, Figure 1. Our understanding of the project is based on our discussions with you, members of the design team, our review of the plans provided by ESM Consulting Engineers, our review of the available geologic and soils data, our May 29, 2015 site visit, and our experience in the area. We understand the site development will consist of a boundary line adjustment, the razing of the existing residence and construction of a new residence in its place along with two new residences accessed from a new north -south shared driveway extending from SW 292nd eet. We anticipate the residences will be one or two-story, wood -framed construction and yfou h may include daylight basement configurations supported on conventional concrete dations. PURPOSE & SCOPE / The purpose of our services was to evaluate the surface and subsurface conditions at he site as a basis for providing geotechnical recommendations and design criteria for the roposed residential development. We also assessed potential adverse impacts to and from the lopes located within the site area. Specifically, our scope of services for the project included a fallowing: 1. Reviewing the available geologic, hydrogeologic and geotechnical data for the site s area; 2. Monitoring the completion of track hoe test pits at the site, depths of up to approximately 10 feet below the existing grades.

We received signed authorization to proceed with our scope of services from Marianne Veeder on May 22, 2015. SITE CONDITIONS Surface Conditions The site consists of a single tax parcel located at 105 SW 292nd Street in the Redondo area of Federal Way, Washington. The site is rectangular in shape, measuring approximately 150 feet wide (east to west) by 260 feet deep (north to south) and encompassing approximately 0.9 acres. The site is currently developed with a single family residence in the NE portion of the site, a gravel driveway, and associated utilities. A sewer easement crosses the parcel from east to west at approximately the north and south midpoint. A older rockery wail along the north margin of the sewer easement situated in the western portion of the site provides approximately 4 to 6 feet of grade separation. The site is bounded by W 292nd Street on the North, 1st Avenue South on the east, a right-of-way easement to the south and existing residential development to the west. Based on a review of topographic data provided by King County public GIS and otaservations in the Field, the site generally slopes down from the southeast to northwest. The southeast portion of the site slopes down below the right-of-way for 1st Avenue South at inclinations of approximately 50 percent and gradually becomes gently sloping after about 100 feet. Below the steeply sloping area, the remainder of the parcel slopes gently to the northwest at inclinations of 7 to 12 percent. Vertical relief of the steep slope area is about 45 to 50 feet, While total topographic relief across the site is on the order of 70 to 75 feet. Surface water was observed in a small drainage channel along the western margin of the site. The surface water appeared to be artificially channelized and discharged from the site into a culvert near the SW 292nd Street right-of-way. No evidence of soil erosion, soil movement or deep-seated landslide activity was observed on this si at the time of our site visit, or is documented on the published geological literature. Site Soils The USDA Natural Resource Conservation Service (NRCS) Web Soil Survey maps the soils in the area of the site as Akierwood S Kitsap soil (AkF) and Indianola loamy fine sand (InC). The Alderwood-Kitsap soils form on slopes of 25 to 70 percent and have a "severe" Veeder.SW292ndSt.GR June 8, 2015 Page 3 that form an stapes of to 15 percent and nave a 'mo erate erosl A copy of the SCS map for the site vicinity is attached as Figure 3. Site Geology The Geological A4ap of the poverty Bay 7.5-minute Quadrangle, Washington by Booth, Waldron, and Troost (2003) indicates the site is underlain by fine-grained facies of glacial deposits of pre -Olympia age and Vashon age recessional sandy lacustrine deposits (Qvrs), The pre -Olympia deposits consist of interbedded gravel, sand and silt that were deposited prior to the Olympia age of glaciation, but are of indeterminate age. These deposits have been subsequently overridden by the continental ice mass associated with Vashon glaciation and are in a dense to very dense condition, The recessional sandy lacustrine deposits were generally deposited during the Vashon Stade of Fraser glaciation. These deposits consist of lightly stratified to laminated sands and sifts deposited in meltwater ponds and lakes during the retreat of the continental ice mass. An excerpt of the above referenced map is included as Figure 4. Subsurface Explorations On March 13, 2015. a GevResources geologist was on site and monitored the excavation of five test pits to depths of up to 8 feet below existing excavated by a small track mounted machine operated by licensed earthwork contact sere The locations of the test pits were selected by GeoResources personnel in the field based on discussions regarding the proposed development, along with site access limitations and consideration for underground utilities. A field geologist from our office continuously monitored the test pits, maintained logs of the subsurface conditions encountered, obtained representative soil samples, and observed pertinent site features. Representative $oil samples obtained from the test pits were placed in sealed plastic bags and taken to a laboratory for further examination and testing as deemed necessary. Each test pit was then backfllled with the excavated soils and bucket tamped in place. The test pits excavated and reviewed as part of this evaluation indicate the subsurface conditions at specific locations only, as actual subsurface conditions Can vary across the site. Furthermore, the nature and extent of such variation would not become evident until additional explorations are performed or until construction activities have begun. Based on our experience in the area and extent of prior explorations in the area, it is our opinion that the sons encountered in the borings are generally representative of the soils at the site. The approximate iocations of the borings are indicated on the attached Site and Exploration Plan as Figure 2. Subsurface Conditions Our test pits encountered variable subsurface conditions that generally confirmed the mapped stratigraphy. The test pits extended to depths ranging from 6 to 8,5 feet below the existing ground surface. Our test pits generally encountered �z fo 1J7 feet of topsoil overlying light brown silty fine to medium sand with intermittent lens of blue silty sand in a medium dense to dense condition to the full depth explored. We interpret these sails s d giacivlacumrine deposits. The soils encountered were visually classified in accordance with the Unified Soil Classification System (USCS) described in Figure 5.

(g) Slopes having gradients greater than 80 percent subject to rockfall during seismic shaking. (h) Any area with a slope of 40 percent or steeper and with a vertical relief of 10 or more feet except areas composed of consolidated rock. A slope is delineated by establishing its toe and toga and is measured by averaging the inclination over at least 10 feet of vertical relief. " From the above listed indicators, we offer the following comments: The slopes on the south side of the parcel are greater than 15 percent, but no permeable sediments over impermeable sediments were observed in our explorations, and no groundwater seepage was observed at the time of our site visit: There was no evidence of recentlhoiocene epoch slope instability on the site at the time of our visit. The drainage in the east portion of the site was relatively gently sloping and did not exhibit any evidence of rapid incision or stream bank erosion at the time of our site visit culverts had also been installed. No area of alluvial fans was noted or was observed on or within the vicinity of the subject site. The site is mapped as "stable" by the Department of Ecology's Coastal Zone Atlas. The site is not mapped as a quaternary slump, earthflow, mudflow, lahar, or landslide by the U.S. Geological Survey or the Department of Natural Resources: There are no slopes greater than 80 percent located on or near the site. There is a slope of greater than 40 percent with more than 10 feet of vertical relief in the southeast cornier of tihe'sfte. Based on our observations and literature review, the more steeply sloping southeast portion of the site meets the technical criteria of a landslide hazard area — Seismic Hazards per Federal Way Revised Code (19.05.070 G (3)) The City of Federal Way Municipal Code defines seismic hazard areas as 'those areas subject to severe risk of earthquake damage as, a result of seismically induced ground shaking, slope failure, settlement or soil liquefaction, or surface fauiting. These conditions occur iii areas underlain by cohesionless soils of low density usually in association with a shallow groundwater table." According the City of Federal Way Municipal Code, the proposed residential plat will be required to be designed and constn.icted in accordance with the 2012intemational Building Code (IBC). Based on the inferred range of Standard Penetration Test {SPT) values, It is our opinion that the project site could be adequately classified as a Site Class D in accordance with the 2015 IBC Section 1813,3.2IASCE 7-05 Table 20.3-1. This is based on the likely range of equivalent SPT (Standard Penetration Test) blow counts for the soil types observed in the site area. These conditions were assumed to be representative for the conditions based on our experience in the vicinity of the site. Veeder.8W292ndSt.GR June 8, 2015 Page 6 Buffers/Setbacks per City of Federal Way Revised Code 19.145.230-240 Per the FWRC 19.145.230, landslide hazard areas shall have a standard buffer of 50 feet, measured from the top, toe, and sides of the slope. Buffers and setbacks depend on the sensitivity of the landslide hazard area and may be reduced within the landslide hazard area when a qualif€ed professional demonstrates that improvements will not cause 0n increased e hazard or will not be at risk of damage by the landslide hazard. Erosion and seismic hazard areas do not have standard buffers; however, all proposed improvements within erosion or seismic hazard areas shall follow the recommendations within this report. improvements within an erosion hazard area shall not increase surface water discharge beyond predevelopment conditions, decrease slope stability on adjacent properties, or adversely impact other critical areas. Based on our site observations and subsurface explorations, it is our opinion a 25-foot .setback is adequate and should be applied to the proposed site development. A reduction of the setback could be achieved by supporting the toe of the slope with an engineered retaining wall. The amount of reduction would be determined by the height and design of the wall. Retaining wall recommendations and design criteria can be made available at your request. CONCLUSIONS Based on our site observations, data review, subsurface explorations and our engin0ering analyses, it is our opinion that the proposed residential development is feasible from a finical standpoint, provided the recommendations included herein are kr_orpo*afed into the rra;ect plans. New residence and other ancillary structures may be supported on new conventional spread footings or floor slabs bearing on competent native soils or on structural fill placed above these native soils. The native soils at the site contain a significant percentage of fines (silt and clay -size particles), which makes them extremely moisture sensitive. These soils will be diffcult or impossible to compact as structural fill in wet weather conditions. We understand that grading, for the most part, vAH tie relatively minor, potentially cuts as much as 8 to 12 feet in the northern and southern portions of the site. It grading activities take place during the winter season, the owner should be prepared to import free -draining granular material for use as structural fill and backnll. Stormwater infiltration on the site does not appear feasible in the native sails. We recommend that stormwater from new impervious surface on the site be collected and conveyed to appropriate discharge point. Alternatively, Low impact Development (LID) options should also be considered for stormwater management. The control of surface and shallow subsurface water in the construction area should increase the overall site stability. Site Preparation and Grading All structural areas on the site to be graded should be stripped of vegetation, organic surface soils, and other deleterious materials including existing sttfesi foundations or abandoned utility lines. Organic topsoil is not suitable for use as structural fill, but may be used for limited depths in non-structural areas. Stripping depths ranging from 12 to 18 inches should be expected to remove these unsuitable soils. Areas of thicker topsoil or organic - bft may be er wontered in areas of heavy vegetation or depressions, several of our ?explorations did encounter upwards of 18 Inches or topsollfdu€f. Where placement of fill material is required, the strippedlexposed subgrade areas should be compacted to a firm and unyielding surface prior to placement of fill material. Excavations for debris removal should be backfilled with structural fill compacted to the densities described in the "Structural Fill" section of this report. Veeder.SW292ndSt.GR June 8, 2015 Page 7 We recommend that a member of our staff verify the ex Led subgrade conditions after e The exposed subgrade soil should be proof -rolled and compacted to a firm and unyielding condition. We recommend that trees be removed by overturning in fill areas so that a majority of the roots are removed. Excavations for tree stump removal should be backfilled with structural fill compacted to the densities described in the "Structural Fill" section of this report. Soft, loose or otherwise unsuitable areas delineated during proof -rolling or probing should be recompacted, if practical, or over -excavated and replaced with structural fill. The depth and extent of overexcavation should be evaluated by our field representative at the time of construction. The areas of fill should be evaluated during grading operations to determine if they need mitigation; recompaction or removal. Structural Fill All material placed as fill associated with mass grading, as utility trench backfill, under building areas, or under roadways should be placed as structural fill. The structural fill should be placed in horizontal tiffs of appropriate thfckness to allow adequate and uniform compaction of each lift. Fill should be compacted to at least 95 percent of MDD (maximum dry density as determined in accordance with ASTM D-1557). The appropriate lift thickness will depend on the fill characteristics and compaction equipment used. We recommend that the appropriate lift thickness be evaluated by our field representative during construction. We recommend that our representative be present during site grading activities to observe the work and perform field density tests. The suitability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (material passing US No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to.achieve. During wet weather, we recommend use of well -graded sand and gravel with less than 5 percent (by weight) passing the CIS No. 200 sieve based on that fraction passing the 314-inch sieve, such as Grave! Backtill for Walls (WSDOT 9-03.12(2)). If prolonged dry weather prevails during the earthwork and foundation installation phase of construction, higher fines content (up to 10 to 12 percent) may be acceptable. Material placed for structural fill should be free of debris, organic matter, trash and cobbles greater than 6-inches in diameter. The moisture content of the fill material should be adjusted as necessary for proper compaction. Suitability of On -Site Materials as Fill During dry weather construction, non -organic on -site soil may be considered for use as structural fill; provided it meets the criteria described above in the `Structural Fill" section and can be compacted as recommended. If the soil material is over -optimum in moisture content when excavated, it will be necessary to aerate or dry the soil prior to placement as structural fill. Shallow soils on the site were observed to be wet of optimum. Based on our explorations and laboratory testing, the native glaciolacustrine soils on site contain a significant percentage of fines. The high fines content makes these soils extremely moisture sensitive and these soils will be difficult to impossible to adequately compact during extended periods of wet weather or where seepage occurs. We recommend that completed graded -areas be restricted from traffic or protected prior to wet weather conditions. The graded areas may be protected by paving, placing asphalt -treated base, a layer of free -draining material such as pit run sand and gravel or clean cruehed rock material containing less than 5 percent fines, or some combination of the above. Veeder.SW292ndSLGR June 8, 2015 Page 8 Temporary Excavations All job site safety issues and precautions are the responsibility of the contractor providing serviceslwork, The following cutifill slope guidelines are provided for planning purposes only. Temporary cut slopes will likely be necessary during grading operations or utility installation. Ail excavations at the site associated with confined spaces, such as utility, trenches and retaining walls, must be completed in accordance with local, state, or federal requirements. Based an current Washington Industrial Safety and Health Act (WISHA, WAC 296-155-66401) regulations, the shallow upper weathered soils on the site would be classified as Type C soils, where as the deeper, stiffer soils would be classified as Type B soils. According to WISHA, for temporary excavations of less than 20 feet in depth, the side slopes in Type B soils should be laid back at a slope inclination of 1 H:1 V, and Type C soils should be laid back at a slope inclination of 1.5H:1 V or flatter from the toe to top of the slope. It should be recognized that slopes of this nature do ravel and require occasional maintenance. All exposed slope faces should be covered with a durable reinforced plastic membrane, jute matting, or other erosion control mats during construction to prevent slope raveling and rutting during periods of precipitation. These guidelines assume that all surface loads are kept at a minimum distance of at least one half the depth of the cut away from the top of the slope and that significant seepage is not present on the slope face. Flatter cut slopes will be necessary where significant raveling or seepage occurs, or if construction materials will be stockpiled along the top of the slope. Whare it is not feasible to slope the site soils back at these inclinations, a retaining structure should be ccnsidcred. `A't'ere retaining structures are greater than 4-feet in height .(bottom of footing to top of structure) or have slopes of greater than 15 percent above them, they should be engineered per Washington Administrative Code (VVAC 51-16-080 item 5). This information Is provided solely for the benefit of the owner and other design consultants, and should not be construed to imply that GeoResources assumes responsibility for job site safety. It is understood that job site safety is the sole responsibility of the project contractor. Foundation Support Based on the subsurface soil conditions encountered across the site, we recommend that spread footings for the new residences be founded on medium dense native soils or on appropriately prepared structural fill that extends to suitable native soils. The soil at the base of the footing excavations should be disturbed as little as possible. All loose, soft or unsuitable material should be removed or recompacted, as appropriate. A representative from our firm should observe the foundation excavations to determine if suitable bearing surfaces have been prepared, particularly in the areas where the foundation will be situated on fill material. We recommend a minimum width of 24 inches for isolated footings and at least 12 Inches for single story and 16 inches for two story continuous wall footings. All footing elements should be embedded at least 18 inches below grade for frost protection. Footings founded as described above can be designed using an allowable soil bearing capacity of 2.500 psf (pounds per square foot) for combined dead and long-term live loads. The weight of the footing and overlying backfill may be neglected. The allowable bearing value may be incrassed by one-third for transient loads such as those induced by seismic events or wind loads. Lateral loads may be resisted by friction on the base of footings and floor slabs and as passive pressure on the sides of footings. We recommend that an allowable coefficient of friction of 0.30 be used to calculate friction between the concrete and the underlying soil. Passive pressure may be determined using an allowable equivalent fluid density of 300 pcf W Veeder.SW292ndSt.GR June 8, 2015 Page 9 (F-Qu .. factor of safety of 1.5 has been applied a these values We estimate that settlements of footings designed and constructed as recommended will be less than 1 inch, for the anticipated load conditions, with differential settlements between comparably loaded footings of 112 inch or less. Most of the settlements should occur essentially as loads are being applied. However,; disturbance of the foundation subgrade during construction could result in larger settlements than predicted. We recommend that all foundations be provided with footing drains. Floor Slab Support Slab -on -grade floors, where constructed, should be supported on the medium dense native soils or on structural fill prepared as described above. Areas of old fill material should be evaluated during grading activity for suitability of structural support. Areas of significant organic debris should be removed. We recommend that floor slabs be directly underlain by a minimum flinch thick pea gravel or washed 5/8 inch crushed rock. This layer should be placed and compacted to an unyielding condition and should contain less than 2 percent fines. A synthetic vapor retarder is recommended to control moisture migration through the slabs. This is of particular importance where the foundation elements are underlain by the silty till or lake sediments, or where moisture a0gration through the slab is an issue, such as where adhesives are used to anchor carpet or file to the slab. A subgrade modulus of 400 kcf (kips per cubic foot) may be used for floor slab design. We estimate that settlement of the floor slabs designed and constructed as recommended, will be 1/2 inch or less over a span of 50 feet. - • 1. . *r_ Utilities We expect that underground utilities, such as sanitary sewer, storm, and water will consist of a series of pipes, vaults, manholes, and catch basins. The utility excavations should be performed In accordance with appropriate governmental guidelines. Utility pipes should be bedded and backfilled in accordance with American Public Works Assoclation (APWA) specifications. We anticipate that the on -site, non -organic soils will be suitable for use as structural backfill. If import soil is used as utility trench backfill, it should consist of a material meeting the wet weather fill recommendations provided in the "Structural Fill" section of this report. We recommend that utility backfill soils be compacted according to the recommendations provided in the "Structural Fill" section of this report. Controlled -density fill (CDF) is most often suitable for use as backfill in any weather condition and could be used as a convenient, but more expensive, alternative to granular backfill soil. CDF backfill does not require compaction but should have a minimum compressive strength of 250 psi commensurate with the application. Pavement Subgrades Pavement subgrade areas should be prepared as previously described in the "Site Preparation" section of this report. The prepared subgrade should be evaluated by proof - rolling with a fully -loaded dump truck or equivalent point load equipment. Soft, loose or wet areas that are disclosed should be recompacted or removed, as appropriate. Over -excavated areas should be backfilled with compacted structural fill and sub -base material. The upper 2 feet of roadway subgrade should have a density of at least 95 percent of the MAD (ASTM D- 1577). Based on our explorations and laboratory testing, subgrade soils on most of the site have a high percentage of fines. As such, the top 9-10 Inches of the pavement section should consist of non -frost susceptible materials (HMA or less than 7% fines). .. - Veeder.SW292ndSt.GR June 8.2015 Iaye 10 Erosion Control Weathering, erosion and the resulting surficiai sloughing and shallow land sliding are natural processes that affect steep slope areas. As noted, no evidence of surficial raveling or sloughing was observed at the site. To manage and reduce the potential for these natural processes, we recommend the following: A No drainage of concentrated surface water or significant sheet flow onto or near the steep slope area. 4`' No fill should be placed within the buffer or setback zone unless retained by engineered retaining walls or constructed as an engineered fill. • Grading should be limited to providing surface grades that promote surface flows away from the top of slope to an appropriate discharge location beyond the toe of the slope, such as Into Puget Sound. Erosion protection measures will need to be in place prior to the start of grading activity on the site. Erosion hazards can be mitigated by applying Best management Practices (BMP's) outlined in the Washington State Department of Ecology's (DOE) Stormwater Management Manual for Western Washington and the City of Federal Way's stormwater requirements (which uses the 2,D09 King County Surface Water Design Manual). Site Drainage Aii grvurid 5urlaces. pavef Tents and sidavial'rs at tl ie site should .,c sloped away from structures. The site should also be carefully graded to ensure positive drainage away from all structures and property lines. Surface water runoff from the roof area, driveways, perimeter footing drains, and wall drains, should be collected, tightlined, and conveyed to an appropriate discharge point. We recommend that footing drains are installed for the residence in accordance with IBC 1807.4.2, and basement walls of utilized) have a wall drain as describe above. The roof drain should not be connected to the footing drain. Based on our site evaluation and laboratory analyses, it is our opinion that the infiltration of stormwater at the site is not feasible. Stormwater should be collected and conveyed to an appropriate discharge point. To manage and reduce the potential for the erosion processes; we recommend that no drainage of concentrated surface water or significant sheet flow be directed onto dr near the steep slope area. Drainage from the roof area, driveways, perimeter footing drains, and wall drains, should be collected and tightiined to an appropriate discharge point. To intercept groundwater and to improve slope stability, we recommend that a "French" or intercepter drain be installed near top of the bluff. The drain will intercept surface water that would flow uncontrolled over the slope, improving the overall stability of the site. Based on the observed subsurface conditions, we anticipate that the drain will need to be at feast 10 feet in depth. The drain should be continued until it daylights or is connected to a catch basin. We recommend that the collected stormwater be diverted to a series of catch basins and dispersed as described above. 'L'. ..iwv.v.hMa(!%SY_-d9"^x 3.Y.s.=N9L�`4•••. •••.__ -. .. .'-.f`°i'^v .. Wet Weather Earthwork Considerations In the Puget Sound area, wet weather generally begins about mid -October and continues through about May, although rainy periods could occur at any time of year. Therefore, it is strongly encouraged that earthwork be scheduled during the dry weather months of June through September. Most of the soil at the site contains sufficient fines to produce an unstable mixture when wet. Such soil is highly susceptible to changes in water Veeder.SW292ndSt.GR June 8, 2015 Page 11 mars re con en exceeds the OPMUM. In addition, during wet weather months, the groundwater levels could increase, resulting in seepage into site excavations, performing earthwork during dry weather would reduce these problems and costs associated with rainwater, construction traffic, and handling of wet soil. However, should wet weather/wet condition earthwork be unavoidable, the following recommendations are provided: The ground surface in and surrounding the construction area should be sloped as much as possible to promote runoff of precipitation away from work areas and to prevent ponding of water. Work areas or slopes should be covered with plastic. The use of sloping, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of the work. • Earthwork should be accomplished in small sections to minimize exposure to wet conditions. That is, each section should be small enough so that the removal of unsuitable soils and placement and compaction of clean structural fill could be accomplished on the same day. The size of construction equipment may have to be limited to prevent soil disturbance. It may be necessary to excavate soils with a backhoe, or equivalent, and locate them so that equipment does not pass over the excavated area. Thus, subgrade disturbance caused by equipment traffic would be minimized. • Fill material should consist of clean, well -graded, sand and gravel, of which not more than 5 percent fines by dry weight passes the No. 200 mesh sieve, based on wet -sieving the fraction passing the %-inch mesh sieve. The gravel content should range from between 20 and 50 percent retained on a No. 4 mesh sieve. The fines should be non -plastic. r No exposed soil should be left uncompacted and exposed to moisture. A smooth - drum vibratory roller, or equivalent, should roll the surface to seal out as much water as possible. • In -place soil or fill soil that becomes wet and unstable and/or too wet to suitably compact should be removed and replaced with clean, granular soil (see gradation requirements above). • Excavation and placement of structural fill material should be observed on a full-time basis by a geotechnical engineer (or representative) experienced in wet weather/wet condition earthwork to determine that all work is being accomplished in accordance with the project specifications and our recommendations. Grading and earthwork should not be accomplished during periods of heavy, continuous rainfall. We recommend that the above requirements for wet weathedwet condition earthwork be incorporated into the contract specifications. Construction Observation We recommend that GeoResources, LLC be retained to observe the geotachnical aspects of construction, particularly the foundations, fill placement and compaction, and drainage activities. This observation would allow us to verify the subsurface conditions as they are exposed during construction and to determine that work Is accomplished in accordance with our recommendations. If conditions encountered during construction differ Veeder_SW292ndSt_GR June 8, 2015 page 12 from those anticipated, we can provide recommendations for the conditions actually encountered. LIMITATIONS We have prepared this report for Marianne Veeder, ESM Consulting Engineering and members of the design team for use in evaluating a portion of this project.

VeederCAR081116A&X Page 1 Veeder Boundary Line Adjustment Federol Way, Washington Critical Areas Report 2.0 EXISTING CONDITIONS This section provides a description of critical areas on and within 1OD-feet of the Veeder property under existing conditions. Critical areas within 100-feet of the work area include a stream, steep slope, and buffers/setbacks associated with the stream and slope (Figure 1). Adjoining properties include similar critical areas. The site was visited in 2015 and 2016 to evaluate critical area conditions. The entire site was walked each time. 2.1 Streams An evaluation of the watercourse crossing the northwest corner of the property was made to determine appropriate water type classification under the City of Federal Way Zoning And Development Code (Chapter 19.05.190). Local, state and federal databases, maps, and reference reports were also searched for any information on the subject watercourse. The watercourse is only briefly acknowledged or mapped by a few jurisdictions (chiefly DNR and City of Federal Way). Aside from mention in a URS stteaim inventory report prepared for the City of Federal in 2001, and a habitat assessment for an upstream development, prepared in 2013, there is no evidence the watercourse has ever received much interest or been studied in detail. A memo from Jim Harris (City of Federal Way Senior Planner) to Isaac Conlen (City of Federal Way Planning Manager) on February 3, 2015 summarizes information available in the City archives with respect to the stream rating2. Multiple evaluations conducted by City of Federal Way, King County, and private consulting firms, along with the City of Federal Way Hearing Examiner, have all concluded that the stream should be classified as a minor stream under the previous Federal Way municipal code. A minor stream is a water course or route, formed by nature, including those which have been modified by humans, along which surface waters naturally and normally flow and which do not contain or support resident or migratory fish. Under the current code this would be a Type N stream. While DNR calls the watercourse a Type F, the DNR work (except in areas where forest practices are ongoing) is normally done remotely and based on large scale slope gradient and basin size estimates. The project site was visited on April 17, 2015 and again on August 4, 2016 by Carl Hadley, a professional fisheries biologist. The watercourse on the subject property was walked in its entirety (about 80 feet). The channel upstream (southwest) of the property (approximately 80 feet) was observed from a vantage point on the subject property. From the northern property line, the watercourse flows north down the slope to Puget Sound. For much of the route "F dbwnslope the watercourse is contained within relatively steep culverts (gradients up to 23 Soundview Consultants, LLC. 2013.

Private property issues prevented seeing the entire route, The discharge point at the beach was examined trewl " : The watercourse on -site is contained within a natural topographic low that meanders across the northwest corner of the property. The channel has a well-defined bed and banks with a width at the ordinary high water (OHW) mark ranging between 2-feet and 5-feet wide (Figure 2). Channel depth at OHW was 6" to 12" with a bank -full depth of over 12". Substrate ranged from small gravel to silt. Habitat was dominated by shallow (0.5") riffle with one small pool about r in depth. Channel gradient was approximately 3 percent. Instrearn flow was estimated to be approximately 0.06 cfs (30 gpm) in April, and about 0.01 cfs (5 gpm) in August. A water temperature of 12 oC was measured in April just after noon on a relatively warm day with no recent rainfall. This low temperature is indicative of a groundwater source, or substantial time flowing through culverts or subsurface. It appears that well more than half of the watercourse has been culverted indicating that it has a long history of being treated more like a stormwater conveyance than a natural watercourse. If fish had ever been observed, piping of the watercourse would not have been allowed. Figure 2. Subject watercourse on'the Veeder property (April 2015). The one minor pool was quietly observed for approximately 10 minutes with no observations of fish. The pool provides the only area meeting classic salmonid habitat characteristics and Is the most likely place where fish would be present if they were in the area. Fish access from Puget Sound into the watercourse is not currently possible. The watercourse discharges onto the beach via a concrete culvert embedded in a seawall (Figure 3). The culvert is buried deeply under an adjacent house, concrete patio, and driveway. Several other culverts are also present along the route up the steep (300-foot, 15 to 20 percent) slope to SW 292nd Street. August 11, 2016 CEDAROCKCONSULTANTS, WC vetderCAR 081216Atx Page 3 v Veeder Boundary Line Adjustment Fede►of May Washington Critical Areas Repart The subject watercourse meets the definition of a "Stream" under the current Federal Way Code. The channel appears to have been naturally formed and contains a natural source of flow. The watercourse is located within a topographic low that extends a long distance up- and downslope. However, the short (80-foot) section of channel on the subject property appears to be the only relatively, undisturbed section of channel in the 750 feet of channel that were observed (Figure 4). The rest of the channel appears to have a long history of being channelized and/or piped. Figure 3. Subject watercourse discharge location to Puget Sound iFigure 4. Subject watercourse upstream (L) and downstream (R) of the Veeder property It is my opinion that this channel is very unlikely to contain fish. There is no possibility for anadromous salmon to access the stream under eAsting conditions due to steep slopes and 'v very long, steep culverts. The few short and steep open channel reaches do not contain habitat that would provide Year-round, or long-term conditions suitable for a resident fish population to complete a life -cycle (spawn and rear). While the channel on the subject property minimally provides some suitable habitat, it is an isolated section among much longer reaches without August 11, 2016 CEDAROCK CONSULTANTS, INC.

It is believed based on the evidence seen to date that there is year-round continuous flow in this channel under normal conditions. Based on the study conducted for this project, I agree with other studies conducted to date that the stream would most appropriately be classified as a Type Np under FWRC 19.05.190.Stream(1). The stream does not meet either of the two criteria in the City code for classification as fish -bearing (FWRC 19.05.190.Stream(2)): (a) Streams where naturally reoccurring use by fish has been documented by a government agency; or (b) Streams that are fish passable, as determined by a qualified professional based on review of stream flow, gradient and natural barriers, and criteria for fish passability established by the Washington Department of Fish and Wildlife. 2.2 Wetlands The site was inspected on August 4, 2016 by a professional wetlands scientist. The site was reviewed using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized by the City of Federal Way and the State of Washington for wetland determinations and delineations. The site was also inspected using the methodology described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), and the Western Mountains, Valleys and Coast region Supplement (Version 2.0) dated June 24, 2010, as required by the US Army Corps of Engineers. Soil colors were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 1990). With the exception of the steep slope in the southeast corner of the site, the site has a gentle slope from the south and east towards a low point on the northwest side of the site containing a well-defined portion of stream. Vegetation on the site consists of an overstory of big leaf maple and red alder with an understory of Himalayan blackberry, salmonberry, and Indian plum. Soil pits excavated throughout the site were found to be a sandy loam soil with colors ranging from 10YR 3/3-3/4. All were found to be dry with no hydric indicators. No areas on the site were found with wetland characteristics. 2.3 Geologic Hazard Areas The property contains an area of steep slope with an average inclination of approximately 50 percent in the southeast corner of the lot (see BLA figure in Appendix). The slope has a 30 foot vertical rise over about 60 horizontal feet. A rockery wall supports part of the slope. The slope August 11, 2016 CEDAROCK CONSULTANTS, INC. VeederCAA081116.docK Page 5 Veeder Boundary line Adjustment Federal Way, Washfn tan Critical Areas Report extends to the south* and east onto neighboring properties. The slope is partially supported with rip -rap and vegetated with trees, and few shrubs, and a great deal of English ivy. Potential geologic hazards on and near the site were examined and evaluated by a licensed geotechnical engineer3. While the more steeply sloping portions of the site meet the technical definition of both an Erosion Hazard and Landslide Hazard area per the code, no evidence of existing geologic hazards (soil erosion, soil movement or deep-seated landslide activity) as defined in FWRC 19.05.070(G) was found on the subject property or is documented In the published geological literature. The steep slope and setback area are located more than 150 feet away from the channel so there is little risk of sediment delivery to the stream as a result of any erosion or slope failure. 2.4 Fish and Wildlife Habitat As described in Section 2.1 no fish are believed to be located on or within more than 300 feet of the site. The wildlife habitat review consisted of a site -specific survey and consultation with the Washington Department of Fish and Wildlife database 4. The site and surrounding lands have been developed mostly as moderate -density single -unit residential housing (Figure 1).

However, overall wildlife habitat quality has been significantly modified by past clearing, fragmentation, and introduction of non-native landscaping species (e.g. English ivy and turf grasses) (Figure 5). Species that may be expected to be found intermittently on this site are coyote, Douglas and eastern grey squirrels, other assorted rodent species, deer, woodpeckers, and song birds. There are a number of large deciduous trees suitable for eagle, hawk, and owl perching on the site. No nesting activity by sensitive species is known to have occurred on the site or within more than 300-feet of the site in the recent past (WDFW 2016). a GeoResources, LLC. 2016.

This section describes potential actions that will be taken within or near critical areas and any proposed changes to the functions or values that could occur. Critical area functions and values for fish and wildlife species are based on WDFW guideliness and other best available science6. 3.1 Streams The on -site stream will be left undisturbed. A 50-foot buffer from OHW as required for Type Np streams under FWRC 19.145.270(1)(b) will also be left undisturbed. No impacts to the stream functions or values are expected under the proposed BLA.

No groundwater with the potential for daylighting was reported during geotechnical analysis of underlying soils. The BLA is not expected to have any adverse effect on wetlands. $.3 Geologic Hazard Areas Under the BLA the steep slope and required setback have been identified (see BLA figure in Appendix). No actions are proposed on the slope or within the slope setback. Project geotechnical engineers have reviewed the proposed BLA and have concluded that based on their site observations, data review, subsurface explorations and engineering analyses, it is their opinion that a residential development is feasible from a geotechnical standpoint, provided that recommendations included in the report are incorporated into the project plans'. 3.4 Fish and Wildlife RAitat The BLA has identified a road alignment for access to the future Lot B. This road will be located in an area covered primarily with existing turf grasses. it will not disturb any critical areas or their buffers/setbacks. Reasonably sized locations that will avoid any disturbance to critical areas or their buffers/setbacks are available for future houses on each of the lots. While some large tree removal may occur with development, there are mitigation opportunities available on the steep slope and within the stream buffer that can provide overall enhancement of fish and wildlife habitat (See Section 4.2). Overall, there will likely be some short term disturbance with expected future development, but no significant long term adverse effects on fish and wildlife habitat. 3.5 Critical Areas Effects Summary Avoidance of significant impacts to critical areas on the site and nearby can reasonably be expected under the proposed BLA layout. No adverse affects on critical areas are predicted. 4.0 .MITIGATION 4.1 Impact Avoidance The primary means of mitigation under the BLA proposed for this property has been avoidance of existing critical areas (stream and geologic hazards) and their buffers/setbacks. Suitable road and house locations are provided in the BLA layout whereby all critical areas can be avoided during final development. With implementation of the following measures, no impacts due to the BLA are expected. 4` Ro ground'disturbance shall take place within the steep slope area or setback, or within the stream or stream buffer.

These opportunities are described below for future consideration when specific redevelopment plans are being prepared. • All exotic plant species (primarily Himalayan blackberry and English ivy) could be removed from the steep slope area and stream buffer. This includes dense infestations of English ivy growing up most of the native trees on the southern half of the property. s Trash and landscaping waste materials (branches, lawn clippings, etc.) could be removed from the stream buffer. s There are opportunities for further enhancement of the stream buffer with native groundcovers, shrubs, and trees.
