Federal December 16, 2008 Sergey Adzhigirey 32022 5`h Avenue SW Federal Way, WA 98023-5615 1 Ch HALL FiLE 33325 8th Avenue South y Mailing Address: PO Box 9718 Federal Way, WA 98063-9718 (253) 835-7000 www. cityoffederalway. com RE: File #08-101266-00-SE; LAKOTA ADDITION, BLOCK 6, LOTS 4,5 & 6 - UTILITIES 30523 28`h Avenue SW, Federal Way Dear Mr. Adzhigirey: On April 7, 2008, the City of Federal Way's Department of Community Development Services received your State Environmental Policy Act (SEPA) checklist for the installation of sewer and water lines within a Category III wetland and within its associated 50-foot buffer. The subject site is zoned Single -Family Residential 15.0. The City determined that the application was incomplete on May 7, 2008, and a letter was sent. On July 3, 2008, the applicant tendered a resubmittal to the City, which was then deemed complete on July 17, 2008. On August 4, 2008, a request for information was sent to the applicant. The applicant then resubmitted plans on October 27, 2008. After review of the October 27, 2008 resubmittal, it appears that all proposed work has been shifted from the west (Dash Point Rd) to the east (281h Avenue South) side of the project. Furthermore, according to the site plan, all work is to occur within right-of-way and outside of any environmentally sensitive area and also limits the water/sewer line to Lot 4. Due to the reconfiguration of the water/sewer line path, there are no impacts to either the Category III wetland (or its buffer) or any steep slopes. Therefore, the project is no longer subject to a SEPA checklist review because the proposed action is exempt. However, please note that the proposed water/sewer line is still subject to a SEPA checklist review if it is larger than 8" in diameter. Lakehaven Utility District generally takes lead agency status when dealing with the installation of their utility lines. In terms of this SEPA checklist review, since the proposed action is now an exempt development activity, there is no need to issue a Determination of Nonsignificance (DNS). Please take this letter as a letter of exemption for the SEPA checklist review based upon the narrative and site plans submitted on October 27, 2008. Additionally, since all work regarding the water/sewer lines take place outside of environmentally sensitive areas, the Land Use Process IV (mentioned in the previous letter) is no longer required. Please obtain any necessary right-of-way permits through the City of Federal Way for any public road work regarding the water/sewer line.

SUPPLEMENTAL SHEET FOR NON -PROJECT ACTIONS Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the proposal, of the types of activities likely to result from the proposal, and if they are likely to affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The proposal is not likely to affect discharge to groundwater. The proposal will not produce, store or release or hazardous substances. Noise production is limited to construction traffic (short-term) and residential vehicular traffic (long-term). Vehicular traffic during construction will likely affect air because of dust, emission from vehicles and equipment. Proposed measures to avoid or reduce such increases: • Limiting operational hours during construction • Selection of equipment and/or power source to be used during construction • Maintenance or construction of vegetated buffer if applicable, to reduce noise ■ Implement Best Management Practices (BMPs) to minimize erosion 2. How would the proposal be likely to affect plants, animals, fish, or marine life? Proposed measures to protect or conserve plants, animals, fish, or marine life: The proposal will not affect animal, fish or marine life. There are no threatened or endangered species known to be on or near the affected geographic area. Trees, shrubs, and groundcovers affected during the excavation for utilities installations will be replaced with native species. Proposed measures to protect or conserve plants, animals, fish, or marine life: • Restore trees, shrubs, and herbaceous covers in the geographic area that is affected by the excavation for utilities. ■ Removal of invasive species in the affected geographic area. • Prevent the re -growth of invasive species in the affected geographic area. 3.

That is located off Dash Point Road and 28th Ave S, Federal Way, King County, WA. It is in NW 1/a of section 12, Township 21N, Range 3E, W.M., King County, WA. Parcel # 41660-0600 Dear Mr. and Mrs. Adzhigirey: At your request we have carried out the necessary investigations to complete the above report in compliance of the scope of work required by The City of Federal Way. The following letter conveys our opinions, findings and conclusions. SITE DESCRIPTION The property under discussion is a strip of land located off the east side of Dash Point Road and the west side of 28 thAve S. At that location both Dash Point Road and 28 th Ave S are directed in the north -south direction slightly to the northwest. Shortly to the th north of the plat site, Dash Point road changes direction to the south west, while 28 Ave S continues north but turns to 30 thAve S. The site generally is located about one mile south of Puget Sound in The City of Federal Way area, King County, WA. At that th location, The Dash Point Road was found to be paved and developed unlike The 28 Ave South. As stated in the above paragraph, the site is located directly east of Dash Point Road. The access to the property is proposed to be utilizing a direct driveway that enters the site from its east side street which is 28 thAve South near the middle of the side. As understood, the subject site has never been previously developed and is almost presently in its natural condition. The site generally contains slopes that may be Page 2 Adzhigirey Geo considered medium to relatively steep. Minor disturbance found near the street but all the site topography remains in the natural condition, with medium dense to dense vegetation. During the site visits, field work and exploration, it was found that adjacent sites, to the north and east of the subject lot, have been developed as single family residence lots. The immediate lots of the same plat to the south of the lot remain undeveloped. The subject site is almost a trapezoidal shaped parcel of land. The west rear leg spans about 107'feet total length with 35'feet straight line and the remaining very flat curve. It runs in the north-west direction along Dash Point Road. Almost in the same direction, the east side is 101'feet long broken line, along The 28 th Ave South. The north is 478'feet and the south side is about 450'feet, both extend in the east -west direction. As previously stated, the property contains medium to steep slopes. The site is at its highest elevation at the east side front of 28m Ave South. From there the ground slopes down westerly to the west and southwest toward Dash Point Road. From the top east area, for about ten feet, the ground slopes with 40% grade to the west. That is reduced to 15% in the next 40'feet. It then increases to an average of 28% for the next 200'feet.. From there till the west the slopes continues to flatten to about 7% in the west direction. However, from the main street, Dash Point up to the property, the slopes are about 65%, for about 15'feet only. In total, the site covers an area of about one acre. Please refer to figure 1, attached to this report. Presently, the drainage of the site is a natural surface drainage that runs westerly from the upper areas in the east, and toward Dash Point. Due to the relatively flatter slopes of the site west area of the site and the dense vegetation, it appears that most of the runoff is contained on site. Based on maps provided to us by the owner, Mr. Adzhigirey, it was found that parts of the property were professionally designated as wetlands. One small area is 15'feet wide, adjacent to the south line about 120'feet from 28d' Ave S. The other about 40'feet wide crosses the site and is about30'feet from dash Point Road. FIELD INVESTIGATION During the month of October 2007, the writer visited the site and carried out a visual examination of the surface features, slope conditions and vegetation. Two test pits were excavated. Test pits allow to investigate and assess the subsurface conditions. The location of these pits is posted on Figure 1 and their description is as per the attached soil logs sheet. Page 3 Adzhigirey Geo For this site, test pits were determined to be sufficient for this investigation for several reasons. The type of soils expected on site was Indianola or Alderwood-Kitsap Loam. The verified soil is evaluated as matching these soils over all of the site areas. These do not present danger of deep landslide due to the relatively denser substratum. In addition, the slopes although steep, are near limits of angle of rest. No weaker layers are located at depth or top, which would result in any type of landslide. There was no seepage or major mottling observed during the investigation in the Indianola. The seepage in The Alderwood is contained in small area with dense substratum. No depressions or tension cracks, which confirm the above considerations. Therefore, in our opinion, the test pits were adequate and sufficient and there were no technical or economical reasons to justified the need of deep soils boring. FINDINGS As mentioned earlier, the site generally, over most of its steep areas, was found to be covered with medium dense to relatively dense vegetation covering. The vegetation were mix of some mature, mid age and young trees, with dense overgrowth of berries, salal and other types. At the time of the visit, and except for a small contained area, the site surface generally was found to be dry and appears to be relatively well drained, with no signs or evidenced of ground water seepage or wide spread water plant loving species. . In the subject parcel, no signs of previous ground movement, as would be evidenced by scarps, toppled or leaning trees, could be found on site. Our observations are detailed in the " seismic hazard" and slope stability and landslide hazard" sections at the end of this report. The parcel appears to be stable and we know of no historical landslide events in the immediate area of the lot. The steep slopes were closely examined and appear to be stable. CONCLUSIONS AND RECOMMENDATIONS 1. Discussion of Development As mentioned earlier, the property under discussion has never been developed. It is proposed for the construction of a single family residence. This report has been prepared to address the proposed development. The access to this site will be through a direct driveway directing west -east from The 2$th Ave South Page 4 Adzhigirey Geo As proposed, no major ground modifications are expected and we see no need for any th change to the site existing topography. The new structure to the east, near 28 Ave South, will be closer to the eastern steeper slopes. For this site it is recommended to install a daylight basement. This will be made to accommodate the topography. It will reduce the amount of cut and fill which result in more economically feasible and more stable structure. However any type of structure may be used as long as complying with the recommendations 2. Soils Characteristics The King County Soil Survey describes the soils of the site, as "InC, Indianola Loamy Fine sand, 4 to 15%". The Soils Conservation Service, states that other types such as Alderwood, Neilton and Everett may be contained with these soils. Based on the examination, in the development proposed site area, we found that, generally the soils contain a large amount of medium to coarse sand, which confirms with the Indianola soils. The western area contained soils that are of type that may be considered Alderwood-Kitsap soils. As per The Soil Conservation Services, The Indianola soils are a well drained soils having rapid permeability in all of its layers. The substratum is a relatively soils that are fine to coarse sand. To the west, the Alderwood soils however are less permeable due to the very dense substratum layer which results in seasonal seepage and light to medium mottling. The slow permeability and denser deep soils may cause perching that may occur atop during heavy wet periods. During our investigation we observed seepage to the depth of about 3.50'feet. For The Indianola, the surface runoff is medium and the erosion hazard is, moderate to severe, for the steep sloped areas. It may be considered similar for The Alderwood- Kitsap. Our exploration have exposed a fine to coarse sand with silt below eight inches depth soils in a medium dense condition up to about 60"inches. At that depth the soils become slightly denser. Very light scattered mottling has been found at the top 42inches layer. In our opinion, the site subsurface investigation reveals that the site soils generally conforms to the above type described in The KCSS in the soils type and sometimes in gradual condition from type to another but in steeper slopes. Please refer to the attached figure 2, for the soils type description. Page 5 Adzhigirey Geo The site soils have adequate bearing capacity to support structural loads. All types of existing soils are well accepted as fill especially the wet season. During these dry periods they may be used provided that they are free of topsoil, debris and rock fragments larger than 6 inches. However, if the moisture in the soil exceeded the optimum moisture, as defined by ASTM D-1557-91, it will become impossible to reach 95% compaction of the maximum dry density of the soils, as defined by the same test. Therefore the use of these soils in the rainy season or periods is acceptable, if compaction is made to reach 95%. Otherwise structural fill may be needed, see table 1 for specification. Generally, during wet weather construction, material with more than 6 percent fines will not be easily workable. For the soils described as medium dense, a bearing capacity of 1500 psf may be used in the foundation design with an adequate factor of safety. A one- third increase in allowable bearing capacity may be utilized for the short term loads such as the case in the wind or seismic loads. 3- Wetlands As previously stated based on maps provided to us by the owner, Mr. Adzhigirey, it was found that parts of the property were professionally designated as wetlands. One small area is 15'feet wide, adjacent to the south line about 120'feet from 281" Ave S. The other about 40'feet wide crosses the site and is about30'feet from dash Point Road. As per the wetland codes, a buffer must be set for the wetland. Based on the maps and the proposed site plan, the house will be to the east to avoid the wetlands. Therefore the development will have no effect on the wetland. 4- Landslide Hazard Generally, Landslide Hazard Area are these area with slope of 30% or more and with a vertical relief of ten or more feet. Also designated as Landslide Hazard Areas are those with over 15%, containing hillsides intersecting geologic contacts with a relatively permeable sediment overlaying a relatively impermeable sediment or bedrock combined with spring groundwater seepage. Similarly are the areas which have a severe limitation for building site development because of slope conditions, according to the Soil Conservation Service. The first condition applies to small eastern and western areas of the site. All of the remaining of the lot is under 30%% and down to about 8% ground slopes. We have found Page 6 Adzhigirey Geo no signs of erosion, or slides and is the site is stable. The mottling and seepage observed in the pits is a sign of seasonal perching, The top less denser layer, about 40"inch deep, is relatively silty soft to medium dense and no construction is proposed in this area. The development is in the sandy soils are the foundation will be recommended to be at the medium dense layer. Although a small eastern area of the site is considered of landslide type due to the slopes, we conclude that it is stable and development may proceed as proposed considering the recommendations of this report. 4- Erosion Hazard Erosion Hazard areas are usually defined as those areas classified having moderate to severe, severe or very severe erosion potential by the Soil Conservation services. Considering the sloped area as InC, that soil has a medium to severe erosion hazard as per The Soil Conservation service. This 30% slopes on site may be considered severe and as such the steeper sloped area of the site may be considered as erosion hazard area that requires special care during and post construction. All other areas of the site are not considered erosion hazard. Please refer to the temporary and permanent erosion sections of this report. 5- Temporary Erosion Measures Generally, the soils erosion hazard depends and its components and slopes. Because of the relatively large amount of fines in the Indianola and Kitsap soils, it is relatively susceptible to erosion when cuts, exposed surfaces exist, especially with wet weather. Long periods of water exposure will cause erosion when the slopes reach about 30%. Therefore, we do not recommend exposure of cuts for long times in wet or windy periods. Our recommendations in this regard will follow and must be considered carefully to protect the site stability. The site topography as exist does appear to necessitate medium cuts during the installation of the structure foundation over the sloped ground. These cuts will be made to accommodate the construction of the utilities, the drainage system, if any, and the foundation. All the exposed temporary or permanent cuts must be protected by maintaining certain slope and protect its surface from erosion, especially during wet periods. The side slopes of the temporary cuts may be maintained at 1H:1.5V for The Kitsap, assuming short period of exposure in the wet season, not to exceed few days. If open for longer periods, in the wet season, we recommend that side cuts be flattened to 1H:1V or Page 7 Adzhigirey Geo to be shored, if over 4.50'feet. The contractor is responsible to comply with the cuts state and federal regulations, beyond the requirements of this report. Retaining structures may be required when developing this site, as proposed in the future by the owner. When needed, the following values may be used for that design: Active lateral earth pressure 35pcf, Non restricted walls. Active lateral earth pressure 45pcf, restricted walls Passive lateral earth pressure 250pcf against native or well compacted Coefficient of friction 0.32 factor of safety of 1.5 is already considered for the coefficient of friction. Areas downslope and surrounding any construction excavation should be protected from any sedimented runoff by the use of silt fences (see the attached detail) or by covering the dirt piles with plastic. Similarly, the concentrated runoff from upslope or surrounding areas should be prevented from entering any construction excavation area by diverting the flow. All the excavated materials must be piled, stored and covered suitably until reused or to be exported. This to be done in such a way not to spill onto slope faces, burying the vegetation in the surrounding or downslope areas. Therefore protection of the lower areas to be undertaken by the use of silt fences or covering of the dirt piles at minimum. 6- Site Drainage and Ground Water The site soils have a rapid permeability in its upper layers and slower at depth. We do not expect major variation due to the development, as proposed when the development is considering an adequate value and system. For this type of soils a 1.50 In/Hr permeability may be used for the Indianola, and is acceptable for the design of the any drainage system of the lot, if needed. If needed, a site infiltration system should be a minimum of 25'feet from the top of the steep slopes. In such case there will be no changes or negative effect regarding the site slopes. Therefore, even if infiltration is to be used, the generated runoff from the new developed impervious area is to have negligent effect on the site area considering: 1- The Indianola is a well draining soils. 2- Comply with top of slope setback 3- Temporary and permanent erosion measure is considered. 4- Utilizing an adequate permeability factors. Page 8 Adzhigirey Geo For the drainage system it is understood that the roof and clean impervious area generated flow may be directed to the wetland or wetland buffer areas. The final drainage system details are beyond the scope of this report. 7- Proposed permanent cuts & fill Temporary cuts were discussed under the previous section " Temporary Erosion Measures". Permanent cuts may be needed, depending on the development. If utilized, it should not exceed 2H:IV. All permanent slopes must be as soon as possible protected at their faces by seeding with grass or a suitable ground covering shrubs. If room does not allow for that approach, a steeper slopes of 1 H:6V may be used and protected with rockeries. Those structures will require permits if their heights exceed 4.0'feet, and must be engineered. Design and construction must comply with the rockery Association, The City of Federal Way and other approved engineering methods. Other retaining structures may be used to provide larger spaces and required to be engineered when over 4.0'feet in height. Permanent fill, if needed, should be also kept at 21-1:1V as a maximum finish slopes. Fill should be compacted as mentioned earlier to 95% compaction. Fill should not be placed over grounds with slopes exceeding 4H:1V, unless tiered, designed and inspected, and as soon as possible vegetated. No runoff is permitted in the east and north setbacks without being controlled. These areas to be well vegetated as detailed later. 8- Foundations and structures All the foundations must rest on the native ground or compacted soil, both verified and inspected to 1500psf with the minimum depth requirements. All the foundations may be conventional spread foundation system. Footing drains are required for this site. For the foundation, or as required in the retaining structures, the drain shall consist of 11/2" washed gravel or rock with a 4"inch PVC perforated pipe embedded in. These lines shall then be directed to the drainage system or to a daylight location 0.50'feet below and 5.00'feet away from the foundation level, with a Page 9 Adzhigirey Geo splash block. The rock must be wrapped with filter fabric. The footing drain lines must not be connected with the roof drain lines for a distance of 5.0'feet minimum. We estimate the postconstruction settlement of the structures where supported on the medium dense, 2000psf, soils to range from 1 /4"inch on native. Maximum differential settlement of the structures should be less than 3/8"inch, measured along 25'feet of continuous wall footing, or between adjacent comparably loaded isolated footings. All the ground surrounding the structure must be sloped away from the foundation with a 2% slopes at minimum or 1% if concrete or paved slabs. 9- Site vegetation removal The construction activities on this site appear to require some removal of the existing vegetation or ground growth to the east for the driveway areas, in preparation for the development. All areas, post construction, adjacent to the structure and the top of the slopes, that were affected by the development, require professional landscaping installation prior to the final occupancy. Utilizing a deep rooted, less maintenance requirements, full year green type of plants are recommended. 10- Seismic hazard Seismic Hazard areas are usually defined as areas which possess either an Alluvial surficial geologic unit and/or recessional outwash overlain by Barneston, Everett, Neilton, Pilchuck or Spannaway soils as per The SCS description. The Kitsap or Indianola are slow drained soils in most of its layers and with deeper and denser substratum. Those soils are not of a type nor in a condition, which is prone to the phenomenon of liquefaction. This occurs as a result of rapid horizontal accelerations during which a rearrangement of the soil particle may cause a build-up in pore pressure. And as this increases the shear resistance decreases to a possible temporary total loss of shear strength. This causes the soil to behave as liquid allowing major settlements. However, this is only possible with soils of very uniform grain size distribution in loose condition, which is not the case of this site. In addition, There is no historical evidence of earthquake- induced slides in this area. Page 10 Adzhigirey Geo 11- Slope Stability and Landslide Hazard We believe that the danger of any landslide on this property caused by natural reasons, such as seismic events, is unlikely. The investigation has shown a stable slope in an undisturbed condition. We have noticed no tension cracks over or at the top of the slopes. Also no signs of depressions, scarps or others defect were seen. No signs of previous ground movements or major erosion were observed, such as leaning trees or old escarpments. This confirms that no dormant, active or stabilized slides exist. The steep slopes are relatively at about the critical grade slope and the degree of rest for these type of soils. Surface erosion to these slopes may occur if affected by the construction. Therefore, these slopes should permanently remain protected by complying with the buffer and a setback and by being maintained permanently vegetated professionally. In addition, the denser condition of the soils and the amount of the slopes with denser depth which presents a landslides resistant soils. 12- Setbacks and buffers The following to be maintained as critical buffer areas or setback areas: 1) No area of the site is required to be maintained as buffer zone except as set by the wetland report. 2) An 8 feet foundation setback from the face of the slopes to be maintained. CONCLUSION The development, as proposed, will have a minor effect on the site erosion, stability and drainage. When the recommendations of the drainage, setback, erosion sections are complied with, any negative effects will be minimum to negligent. In conclusion, we believe based on the above, that the site should not experience landslides as long as protected from erosion, drainage problems and the new development maintains enough setbacks with adequate foundations.

That is located off Dash th Point Road and 28 Ave S, Federal Way, King County, WA. It is in NW V4 of section 12, Township 21N, Range 3E, W.M., King County, WA. Dear Mr. Shramovych: At your request we have carried out the necessary investigations to complete the above report in compliance of the scope of work required by The City of Federal Way. The following letter conveys our opinions, findings and conclusions. SITE DESCRIPTION The property under discussion is a strip of land located off the east side of Dash Point Road and the west side of 28-th Ave S. At that location both Dash Point Road and 28th Ave S are directed in the north -south direction slightly to the northwest. Shortly to the north of the plat site, Dash Point road changes direction to the south west, while 28th Ave th S continues north but turns to 30 Ave S. The site generally is located about one mile south of Puget Sound in The City of Federal Way area, King County, WA. At that location, The Dash Point Road was found to be paved and developed unlike The 28th Ave South. As stated the site is located directly east of Dash Point Road. The access to the property is proposed to be through a direct driveway that enters the site from its west side, Dash Point Road, and near the south corner. As understood, the subject site has never been previously developed and is presently almost in its natural condition. The site generally contains slopes that may be considered medium to relatively steep. As stated, all the site topography remains in the natural condition, with medium dense to dense vegetation. Page 2 Shramovych Geo During the site exploration, it was found that adjacent sites, to the north and east of the subject lot, have been developed as single family residence lots. The immediate lots of the same plat to the north of the lot remain undeveloped. The subject site is a trapezoidal parcel of land. The west rear leg spans about 107feet in the north-west direction along Dash Point Road. Almost in the same direction, the east side is 102'feet long, along The 28 th Ave South. Both the north and south sides, of about 466'and 452'feet respectively, extend in the east -west direction. As previously stated, the property contains medium to steep slopes. The site is at its highest elevation at the southwest corner, front of 28 Ave South. The ground, then, slopes down toward Dash Point'Road. From the top east area, and except for a small comer of about 30°/0, the ground slopes with 23% grade to the west. It then continues in the same direction and reduce gradually down to about 8% slopes when about 100'feet from Dash Point Road. As stated, near Dash Point road, the slopes are about 10%. However, from this street, Dash Point up to the property, the slopes are about 65%, for about 15'feet only. In total, the site covers an area of about one acre. Please refer to figure 1, attached to this report. Presently, and over the slopes, the drainage of the site is a natural surface drainage that runs westerly from the upper areas in the east, and toward Dash Point. Due to the relatively flatter slopes that cover most of the site and the dense vegetation, it appears that _ Mgost of the, runoff is contained on site. FIELD INVESTIGATION During the month of September 2005, the writer visited the site and carried out a visual examination of the surface features, slope conditions and vegetation. Two test pits were excavated utilizing a large size backhoe. Test pits allow to investigate and assess the subsurface conditions. The location of these pits is posted on Figure 1 and their description is as per the attached soil logs sheet. For this site, test pits were determined to be sufficient for this investigation for several reasons. The type of soils expected on site was Indianola or Alderwood-Kitsap Loam. The verified soil is evaluated as matching these soils over all of the site areas. These do not present danger of deep landslide due to the relatively denser substratum. Page 3 Shramovych Geo In addition, the slopes although relatively steep, are near limits of angle of rest. No weaker layers are located at depth or top, which would result in any type of landslide. There was no seepage or major mottling observed during the investigation in the Indianola. The seepage in The Alderwood is contained in small area with dense substratum. No depressions or tension cracks, which confirm the above considerations. Therefore, in our opinion, the test pits were adequate and sufficient and there were no technical or economical reasons to justified the need of deep soils boring. FINDINGS As mentioned earlier, the site generally, over most of its steep areas, was found to be covered with medium dense to relatively dense vegetation covering. The vegetation were mix of some mature, mid age and young trees, with dense overgrowth of berries, salal and other types. At the time of the visit, and except for a small contained area, the site surface generally was found to be dry and appears to be relatively well drained, with no signs or evidenced of ground water seepage or wide spread water plant loving species. In the subject parcel, no signs of previous ground movement, as would be evidenced by scarps, toppled or leaning trees, could be found on site. Our observations are detailed in the " seismic hazard" and slope stability and landslide hazard" sections at the end of this report. The parcel appears to be stable and we know of no historical landslide events in the 1 rrnnediate area of the lot. The steep slopes were closely examined and appear to be stable. -- CONCLUSIONS AND RECOMMENDATIONS 1. Discussion of Development As mentioned earlier, the property under discussion has never been developed. It is proposed for the construction of a single family residence. This report has been prepared to address the proposed development. The access to this site will be through a direct driveway directing west -east from The Dash Point Road, along the south property line. As proposed, no major ground modifications are expected and we see no need for any change to the site existing topography. However, the new structure to the east, near 28th Ave South, will be closer to the eastern area that contains the relatively steeper slopes. Page 4 Shramovych- Geo 2. Soils Characteristics The King County Soil Survey describes the soils of the site, as "InC, Indianola Loamy Fine sand, 4 to 15%". The Soils Conservation Service, states that other types such as Alderwood, Neilton and Everett may be contained with these soils. As per The Soil Conservation Services, The Indianola soils are a well drained soils having rapid permeability in all of its layers. The substratum is a relatively soils that are fine to coarse sand. The aderwood however are less permeable due to the very dense substratum layer which resuls in seasonal seepage and light to medium mottling. The slow permeability and denser deep soils may cause perching that may occur atop during heavy wet periods. During our investigation we observed seepage to the depth of about 3.50'feet in a limited area. Based on the examination, in the site area, we found that generally the soils contain a large amount of medium to coarse sand, which confirms with the Indianola soils. A contained area, which spans as about 35'feet wide vein crossing from the south to the north-west, across the site near the east area may be considered Alderwood-Kitsap soils. For The Indianola, the surface runoff is medium and the erosion hazard is moderate to severe, for the steep sloped areas. It may be considered similar for The Alderwood-Kitsap contained vein. Our exploration have exposed a silty fine sand to coarse sand with silt below two feet depth soils in a medium dense condition up to about 60"inches: At that depth the soils become: slightly denser: Very light scatterectmottling has been found at the top 1 Sinches layer. No seepage was seen. A vein crossing from south line then directing north- westerly, as described earlier, was found to be of impervious substratum at about 3.5'feet and very silty atop. This has created a route for seasonal seepage. In our opinion, the site subsurface investigation reveals that the site soils generally conforms to the above type described in The KCSS in the soils type and sometimes in gradual condition from type to another but in steeper slopes. Please refer to the attached figure 2, for the soils type description. The site soils have adequate bearing capacity to support structural loads. All types of existing soils are well accepted as fill especially the wet season. During these dry periods they may be used provided that they are free of topsoil, debris and rock fragments larger than 6 inches. Page 5 Shramovych- Geo However, if the moisture in the soil exceeded the optimum moisture, as defined by ASTM D-1557-91, it will become impossible to reach 95% compaction of the maximum dry density of the soils, as defined by the same test. Therefore the use of these soils in the rainy season or periods is acceptable, if compaction is made to reach 95%. Otherwise structural fill may be needed, see table 1 for specification. Generally, during wet weather construction, material with more than 6 percent fines will not be easily workable. For the soils described as medium dense, a bearing capacity of 1500 psf may be used in the foundation design with an adequate factor of safety. A one- third increase in allowable bearing capacity may be utilized for the short term loads such as the case in the wind or seismic loads. 3- Landslide Hazard Generally, Landslide Hazard Area are these area with slope of 30% or more and with a vertical relief of ten or more feet. Also designated as Landslide Hazard Areas are those with over 15%, containing hillsides intersecting geologic contacts with a relatively permeable sediment overlaying a relatively impermeable sediment or bedrock combined with spring groundwater seepage. Similarly are the areas which have a severe limitation for building site development because of slope conditions, according to the Soil Conservation Service. Except for the entrance, none of these conditions apply to any place of the site. All of the lot is under 30%% and down to about 8% ground slopes. We have found no signs of erosion, or slides and is the site is stable. The mottling and seepage observed in the vein is a sign of seasonal. perching; The top less denser layer; about 40"inch deep, is relatively silty soft and if happens to be in the development area, the foundation will be recommended to be below to the dense layer, which will eliminate its effect. Therefore, although this small eastern area of the site is considered of landslide type due to the slopes, we conclude that it is stable and development may proceed as proposed considering the recommendations of this report. 4- Erosion Hazard Erosion Hazard areas are usually defined as those areas classified having moderate to severe, severe or very severe erosion potential by the Soil Conservation services. Considering the sloped area as InC, that soil has a medium to severe erosion hazard as per The Soil Conservation service. This 30% slopes on site may be considered severe and Page 6 Shramovych- Geo as such the steeper sloped area of the site may be considered as erosion hazard area that requires special care during and post construction. All other areas of the site are not considered erosion hazard. Please refer to the temporary and permanent erosion sections of this report. 5- Temporary Erosion Measures Generally, the soils erosion hazard depends and its components and slopes. Because of the relatively large amount of fines in the Indianola and Kitsap soils, it is relatively susceptible to erosion when cuts, exposed surfaces exist, especially with wet weather. Long periods of water exposure will cause erosion when the slopes reach about 30%. Therefore, we do not recommend exposure of cuts for long times in wet or windy periods. Our recommendations in this regard will follow and must be considered carefully to protect the site stability. The site topography as exist does appear to necessitate medium cuts during the installation of the structure foundation over the sloped ground. These cuts will be made to accommodate the construction of the utilities, the drainage system, if any, and the foundation. All the exposed temporary or permanent cuts must be protected by maintaining certain slope and protect its surface from erosion, especially during wet periods. The side slopes of the temporary cuts may be maintained at 1 H:1.5 V for The Kitsap, assuming short period of exposure in the wet season, not to exceed few days. If open for longer periods, in the wet season, we recommend that side cuts be flattened to 1H:1V or to be shored, if -over 4.50'feet. The contractor is responsible to comply with the cuts state and federal. regulations, beyond the requirements of this report. Retaining structures may be required when developing this site, as proposed in the future by the owner. When needed, the following values may be used for that design: Active lateral earth pressure 35pcf, Non restricted walls. Active lateral earth pressure 43pcf, restricted walls Passive lateral earth pressure 250pcf against native or well compacted Coefficient of friction 0.32 factor of safety of 1.5 is already considered for the coefficient of friction. Areas downslope and surrounding any construction excavation should be protected from any sedimented runoff by the use of silt fences (see the attached detail) or by covering the dirt piles with plastic. Similarly, the concentrated runoff from upslope or surrounding Page 7 Shramovych- Geo areas should be prevented from entering any construction excavation area by diverting the flow. All the excavated materials must be piled, stored and covered suitably until reused or to be exported. This to be done in such a way not to spill onto slope faces, burying the vegetation in the surrounding or downslope areas. Therefore protection of the lower areas to be undertaken by the use of silt fences or covering of the dirt piles at minimum. 6- Site Drainage and Ground Water The site soils have a rapid permeability in its upper layers and slower at depth. We do not expect major variation due to the development, as proposed, the developed impervious area is about 15% of the total area and may be allowed surface drainage, if acceptable to The City codes. However, If needed, an infiltration may be installed in the Indianola area. For this type of soils a 1.50 In/Hr permeability may be used for the Indianola, and is acceptable for the design. If needed, a site infiltration system should be a minimum of 25'feet from the top of the steep slopes and 15feet from the structure. In such case there will be no changes or negative effect regarding the site slopes. Therefore, even if infiltration is to be used, the generated runoff from the new developed impervious area is to have negligent effect on the site area considering: 1- Temporary and permanent erosion measure is considered. 2- A 25'feet separation to the top of the slopes is used. 3- Utilizing an adequate permeability factors. It appears that the Kitspa-Alderwood vein route seasonal seepage within. A two and half feet wide and down to the dense layer a minimum of four and half feet, French drain trench, to be installed at the upper side of the structure running north -south. It should be wrapped in geo fabric from all sides. It should be fitted with a two six inch perforated pipes that are also wrapped in fabric. The pipes to exit the trench to a system or to the surface at an area at least 30feet away from the house lower side. The trench to extend about the width of the site. If located within or 20'feet near the structure area, the vein top soft layers must be removed completely and replaced with structural fill or using the site sandy soils compacted as stated before. 7- Proposed permanent cuts & fill Temporary cuts were discussed under the previous section " Temporary Erosion Measures". Page 8 Shramovych- Geo Permanent cuts may be needed, depending on the development. If utilized, it should not exceed 2H:IV. All permanent slopes must be as soon as possible protected at their faces by seeding with grass or a suitable ground covering shrubs. If room does not allow for that approach, a steeper slopes of 1H:6V may be used and protected with rockeries. Those structures will require permits if their heights exceed 4.0'feet, and must be engineered. Design and construction must comply with the rockery Association, The City of Federal Way and other approved engineering methods. Other retaining structures may be used to provide larger spaces and required to be engineered when over 4.0'feet in height. Permanent fill, if needed, should be also kept at 2H:1 V as a maximum finish slopes. Fill should be compacted as mentioned earlier to 95% compaction. Fill should not be placed over grounds with slopes exceeding 4H:IV, unless tiered, designed and inspected, and as soon as possible vegetated. No runoff is permitted in the east and north setbacks without being controlled. These areas to be well vegetated as detailed later. 8- Foundations and structures All the foundations must rest on the native ground or compacted soil, both verified and inspected to 1500psf with the minimum depth requirements. All the foundations may be conventional spread foundation system. Footing drains are required for this site. For the foundation, or as -required in theretaining structures, the drain shall consist of 11/2" washed gravel or rock with a 4"inch PVC perforated pipe embedded in. These lines shall then be directed to the drainage system or to a daylight location 0.50'feet below and 5.00'feet away from the foundation level, with a splash block. The rock must be wrapped with filter fabric. The footing drain lines must not be connected with the roof drain lines for a distance of 5.0'feet minimum. We estimate the postconstruction settlement of the structures where supported on the medium dense, 2000psf, soils to range from 1 /4"inch on native. Maximum differential settlement of the structures should be less than 3/8"inch, measured along 25'feet of continuous wall footing, or between adjacent comparably loaded isolated footings. All the ground surrounding the structure must be sloped away from the foundation with a 2% slopes at minimum or 1 % if concrete or paved slabs. As mentioned earlier, if located within or near the structure area, the vein soft layers must Page 9 Shramovych- Geo removed and replaced with structural fill or the site sandy soils compacted as stated before. The foundation must rest on the dense soils. 9- Site vegetation removal The construction activities on this site appear to require some removal of the existing vegetation or ground growth to the east and the west and for the driveway areas, in preparation for the addition. All areas, post construction, especially to the eastern, adjacent to the structure and the top of the slopes, that were affected by the development, require professional landscaping installation prior to the final occupancy. A deep rooted, less maintenance requirements type of plants are recommended. 10- Seismic hazard Seismic Hazard areas are usually defined as areas which possess either an Alluvial surficial geologic unit and/or recessional outwash overlain by Barneston, Everett, Neilton, Pilchuck or Spannaway soils as per The SCS description. The Kitsap or Indianola are slow drained soils in most of its layers and with deeper and denser substratum. Those soils are not of a type nor in a condition, which is prone to the phenomenon of liquefaction. This occurs as a result of rapid horizontal accelerations during which a rearrangement of the soil particle may cause a build-up in pore pressure. And as this increases the shear resistance decreases to a possible temporary total loss of shear strength. This causes the soil to behave as liquid allowing major settlements. However, this is only possible with soils of very uniform grain size distribution in loose condition, which is not the case of this site. In addition, There is no historical evidence of earthquake- induced slides in this area. 11- Slope Stability and Landslide Hazard We believe that the danger of any landslide on this property caused by natural reasons, such as seismic events, is unlikely. The investigation has shown a stable slope in an undisturbed condition. We have noticed no tension cracks over or at the top of the slopes. Also no signs of depressions, scarps or others defect were seen. No signs of previous ground movements or major erosion were observed, such as leaning trees or old escarpments. This confirms that no dormant, active or stabilized slides exist. The steep Page 10 Shramovych- Geo slopes are relatively at about the critical grade slope and the degree of rest for these type of soils. Surface erosion to these slopes may occur if affected by the construction. Therefore, these slopes should permanently remain protected by being buffered and a setback should be maintained and permanently vegetated professionally. In addition, the denser condition of the soils and the amount of the slopes with denser depth which presents a landslides resistant soils. 12- Setbacks and buffers The following to be maintained as critical buffer areas or setback areas: 1) No area of the site is required to be maintained as buffer zone.. 2) An 8 feet foundation setback from the face of the slopes to be maintained. CONCLUSION The development, as proposed, will have minor effect on the erosion and site drainage. If the recommendations under the drainage section is complied with, any negative effects will be minimum to negligent. In conclusion, we believe based on the above, that the site should not experience landslides as long as protected from erosion, drainage problems and the new development maintains enough setbacks with adequate foundations.

Maos Figure 1.0 Vicinity Map 3.0 Methodology The field wetland delineation and wetland assessment were performed using the Routine Small Area Methodology as described in Part IV, Section D of the Corps of Engineers Wetlands Delineation Manual (COE, 1987) and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). The Routine Small Area Methodology is "used when the project area is small, plant communities are homogeneous, plant community boundaries are abrupt, and the project is not controversial". The wetland determination was based on the presence of the three criteria for jurisdictional wetlands: hydric soils, wetland hydrology, and hydrophytic vegetation. All three criteria must be present in order to classify an area as a wetland. June 2006 1 J. S. Jones and Associates, Inc. The field delineation and data collection were completed on May 17, 2006. The wetland boundaries were marked with consecutively numbered orange flagging. Wetland boundaries will be surveyed prior to any development proposal. Approximate location of wetland boundaries, buffers, and sample locations are presented on the attached wetland sketch. The assessment included a review of the USDA Soil Conservation Service's Soil Survey of King County Area, Washington (Snyder, et. al., 1973). Wetlands were rated and wetland functions were assessed using the Washington State Wetland Rating System for Western Washington developed by the Department of Ecology. 4.0 General Site Description The site is a 1.03-acre parcel with a forested plant community. The parcel is approximately 474.3 feet long and 103.46 feet wide. The property is bordered by undeveloped forested parcel to the north and south, Southwest Dash Point Road is to the west and 28th Avenue Southwest is to the east. The site is in a slope greater than 15% from east to west. The plant community is dominated by big -leaf maple, red alder, Douglas fir, vine maple, Indian plum, stinging nettle, lady fern, sword fern, slough sedge, skunk cabbage, salmonberry, Himalayan blackberry. The site is in the drainage basin of Dumas Bay in the Central Puget Sound watershed and WRIA 9 (Duwamish-Green). 5.0 Vegetation 5.1 Vegetation Methodology Hydrophytic vegetation has adaptations that allow these species to survive in saturated or inundated environments. These environments are classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, 1979). The probability of species being found in wetland environments has been determined by the U.S. Fish and Wildlife Service in the National List of Vascular Species that Occur in Wetlands: 1996 National Summary (USFWS, 1996). An indicator status was applied to each species according to its probability of occurring in wetlands (see Table 1.0). Vegetation data was recorded at three sample locations distributed across the property with at least one sample location in each plant community. At each sample location, the dominant species were assessed by indicator status to determine if the plant community was predominantly hydrophytic. Rules for determining dominant species were established in the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). Dominants were determined using the 50/20 rule. Using this rule, percent cover was added by order of descending cover until 50% cover was reached. These species were considered dominants. The next most common species was also included as a dominant if it had over 20% cover. Species with less than 5% cover were not considered dominant species.

June 2006 2 J. S. Jones and Associates, Inc. 5.2 Vegetation Results At sample location 1 (SL-1), the plant community is dominated by Indian plum (Oemleria cerasiformis, FACU), big -leaf maple (Acer macrophyllum, FACU), and sword fern (Polystichum munitum, FACU). The plant community is non-hydrophytic because no more than 50% of the dominant species are FAC, FACW, or OBL (see Table 2 and attached data forms). At SL-2, the plant community is dominated by big -leaf maple (Acer macrophyllum, FACU), sword fern (Polystichum munitum, FACU), Indian plum (Oemleria cerasiformis, FACU), lady fern (Athyrium filix femina, FAC+), Oregon grape (Mahonia nervosa, FACU), stinging -nettle (Urtica dioica, FAC+), English ivy (Hedera helix, NL), and beaked hazelnut (Corylus cornuta, FACU). The plant community is non-hydrophytic because no more than 50% of the dominant species are FAC, FACW, or OBL (see Table 2 and attached data forms). At SL-3, the plant community is dominated by big -leaf maple (Acer macrophyllum, FACU), Indian plum (Oemleria cerasiformis, FACU), stinging nettle (Urtica dioica, FAC+), salmonberry, (Rubus sp-getabilis, FAC+), beaked hazelnut (Corylus cornuta, FACU), English ivy (Hedera helix, NL), s1g4gh sedge (Carex obnupta, OBL), spreading wood fern (Dryopteris austriaca, FACW), lady fern (Athyrium filix femina, FAC+), and skunk cabbage (Lysichiton americanum, OBL). The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW, or OBL.

Hydrology 6.1 Hydrology Methodology The Washington State Wetlands Identification and Delineation Manual requires inundation, flooding, or saturation to the surface for at least 5% of the growing season to satisfy the hydrology requirements for jurisdictional wetlands (DOE, 1997). Areas that are saturated between 5% and 12.5% of the growing season may or may not be wetlands. The growing season can either be defined by the number of frost -free days (temperatures above 28T), or the period during which the soil temperature at a depth of 19.7 inches is above biological zero (41OF). The presence of wetland hydrology was determined at each sample location by evaluating a variety of direct and indirect indicators, consistent with the Washington State Wetlands Identification and Delineation Manual and the U.S. Army Corps of Engineers Wetland Delineation Manual. In addition to direct visual observation of inundation or saturation, secondary hydrologic indicators were used to infer wetland hydrology. Secondary indicators include oxidized channels (rhizospheres) associated with living roots and rhizomes, water marks on vegetation or fixed objects, drift lines, water -borne sediment deposits, water stained leaves, surface scoured areas, wetland drainage patterns, morphological plant adaptations, and hydric soil characteristics. Another secondary indicator is the FAC-Neutral test, which is used to determine if the plant community is hydrophytic when all species with FAC indicator status are disregarded. 6.2 Hydrology Results SL-1 does not have wetland hydrology. The soil profile is dry to the surface. The water table is not present within the upper 18 inches from the surface. There are no indicators of wetland hydrology. SL-2 does not have wetland hydrology. The soil profile is dry to the surface. The water table is not present within the upper 18 inches from the surface. There are no indicators of wetland hydrology. SL-3 does not have wetland hydrology. The soil profile is dry to the surface. The water table is not present within the upper 18 inches from the surface. There are no indicators of wetland hydrology. 7.0 Soils 7.1 Soils Methodology Hydric soils are soils that are "saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (COE, 1987)." They are either organic soils (peats and mucks), or are mineral soils that are saturated long enough to produce soil properties associated with a reducing environment. These soils have hydric characteristics such as a reduced matrix (a matrix that changes color when exposed to air), redox depletions (gleying), or redox concentrations (mottles). June 2006 4 J. S. Jones and Associates, Inc. Soils were visually assessed for hydric characteristics and organic content in an 18-inch soil pit at each sample location. In Washington State, soil color is the main indicator used to determine if a soil is considered hydric. Soil color immediately below the "A" horizon or at a depth of 10 inches below ground surface was determined using Munsell Soil Color Charts (MacBeth, 1990). Soils that had a one-chroma matrix or a two-chroma matrix with mottles were determined to be hydric. 7.2 Soil Series The on -site soils were mapped by the USDA Soil Conservation Service (SCS) as Indianola fine sand (InC) (see Figure 2). "The Indianola series is made up of somewhat excessively drained soils that formed under conifers in sandy, recessional, stratified glacial drift". "In a representative profile, the upper 30 inches is brown, dark yellowish -brown, and light olive - brown loamy fine sand"(Snyder, et. al., 1973). Figure 2. Soil Map of Project Site (King County Soil Survey Sheet 15, Plate 04). June 2006 5 J. S. Jones and Associates, Inc. 7.3, Soils Results The soil at SL-1 is a non-hydric Indianola fine sandy loam. From 0 to 8 inches, the soil is a brown (I OYR 4/3) Indianola fine sandy loam. From 8 to 14+ inches, the soil is a dark yellowish brown (I OYR 4/4) Indianola fine sandy loam (see Table,3). The soil is non-hydric because it has a four-chroma matrix immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). The soil at SL-2 is a non-hydric Indianola fine sandy loam. From 0 to 10 inches, the soil is a brown (I OYR 4/3) Indianola fine sandy loam. From 10 to 18+ inches, the soil is a dark yellowish brown (I OYR 4/4) Indianola fine sandy loam (see Table 3). The soil is non-hydric because it has a four-chroma matrix immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). The soil at SL-3 is a non-hydric Indianola fine sandy loam. From 0 to 10 inches, the soil is a very dark brown (1 OYR 2/2) Indianola fine sandy loam. From 10 to 16+ inches, the soil is a dark grayish brown (I OYR QI)%Indianola fine sandy loam (see Table 3). The soil is non-hydric because it has a two-chr®ma matrix without mottles immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997).

The wetland is part of a wetland system adjacent to the subject property. Its hydrogeomorphic classification is a slope wetland. The main sources of wetland hydrology are precipitation, surface water inflows, and seepage. The soils are a hydric one to two chroma matrix Indianola fine sandy loam with sulfidic odor or common, medium-sized, prominent mottles. The wetland has palustrine scrub shrub (PSS) and palustrine forested (PFO) classes of vegetation (Cowardin, 1979). The plant community is dominated by skunk cabbage, slough sedge, common horsetail, unidentified grass, lady fern, spreading wood fern, stinging nettle, salmonberry, vine maple, red -osier dogwood, red alder, and Indian plum. The wetland has a total function score of 45 and is rated a Category III wetland (see Table 4). The wetland has a score of 25 points for habitat functions. According to Section 22-1.357 (b) (3) of the Federal Way City Code (FWCC), "Category III wetlands shall have a standard buffer width of 50 feet for wetlands that are greater than 10,000 square feet in area". June 2006 6 J. S. Jones and Associates, Inc. The remainder of the subject property is upland. Originally, this project include the adjoining parcels to the south, but was split into separate reports. Sample locations for this wetland were collected but fell on adjoining properties to the south. A non-hydrophytic plant community is present, dominated by big -leaf maple, Indian plum, Oregon grape, beaked hazelnut, and sword fern. The soil is a non-hydric, two to four-chroma matrix Indianola fine sandy loam. 9.0 Functional Assessment The wetland functions were assessed using the 2004 DOE Wetland Rating System for Western Washington. The rating system scores the wetland based on characteristics that contribute to habitat, hydrologic and water quality functions (see Table 4 and attached DOE Wetland Rating Forms). The wetland has potential to perform water quality functions because it has dense, woody, vegetation greater than half of the wetland area that trap sediments and pollutants from surface runoff or groundwater. The wetland has an opportunity to improve water quality because untreated water from residential areas, parking lots, and roads drains into the wetland and downslope. The wetland has potential to perform hydrologic functions by reducing flooding and stream erosion downslope. The dense, uncut, rigid vegetation that covers greater than 1/2 of the wetland will help in reducing water velocity during peak flows that would otherwise flow directly into properties downstream. The wetland has opportunity to reduce the impact of flooding because it helps protect downstream properties during storm events. The wetland has potential to provide habitat functions for wildlife because it has three types of vegetation classes with a moderate interspersion of plant species. There are special habitat features such as large, downed woody debris, standing snags, and thin -stemmed vegetation or woody branches that can be used by wildlife. The wetland has opportunity to provide habitat for wildlife because the condition of the wetland buffer is relatively undisturbed and the corridors and -connections to the larger habitat in the watershed are relatively undisturbed and unbroken.

Impacts will not exceed those required by the Federal Way City Code (FWCC). 11.0 Authority This wetland determination is in accordance with Section 404 of the Clean Water Act, the objective of which is to "maintain and restore the chemical, physical, and biological integrity of the waters of the United States (DOE, 1997)." Wetlands are "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (EPA, 40 CFR 230.3 and CE, 33 CFR 328.3)." 12.0 Limitations Wetland determinations and delineations are not final until approved by regulatory agencies and/or local jurisdictions; J S. Jones and Associates, Inc. does not guarantee acceptance or approval by regulatory agencies, or that any intended use will be achieved. 13.0 References Cowardin, Lewis M. 1979.

If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. To complete the nextpart of data sheet you will need to determine the H dro eomor- hic Glass o the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form — western Washington 2 August 2004 Classification of Vegetated Wetlands for Western WashinLyton ` Wetland Name:\; l Z- :flx: r '.: � � ,�/{ �ej Date: I-Arelhe water levels in the wetland usually controlled by tides (i.e. ' except during floods)? � go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES -- Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) 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 rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separAtely in the earlier editions, and this separation is being kept in this revision. To mazrftain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. Is the,�topography within the wetland flat and precipitation is only source (>90%) of water to it. 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 wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water (without any vegetation on the surface) where at least 20 acres (8 ha) are permanently inundated (ponded or flooded); At least 30% of the open water area is deeper than 6.6 ft (2 m)? Ggo to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the wetland 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? 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 <3ft diame- nd less than 1 foot deep). NO - go to 5 kS he wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average, to answer "yes. " The wetland can contain depressions that are filled with water when the river is npoding, NO, -'go to 6 YES — The wetland class is Riverine Wetland Rating Form — western Washington 3 August 2004 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present, is higher than the interior of the �vet�aatd. No" go to 7 YES — The wetland class is Depressional 7. Is the wetland located in a very flat area with no obvious depression and no stream or river running through it and providing water. The wetland seems to be maintained by high groju-ndwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO = go to 8 YES — The wetland class is Depressional S. Your wetland seems to be difficult to classify. 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. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetlarxd.boundary. Use the following table to identify the appropriate class to use for the rating systerap �f you have several HGM classes present within your wetland. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class. If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

The Routine Small Area Methodology is "used when the project area is small, plant communities are homogeneous, plant community boundaries are abrupt, and the project is not controversial". The wetland determination was based on the presence of the three criteria for jurisdictional wetlands: hydric soils, wetland hydrology, and hydrophytic vegetation. All three criteria must be present in order to classify an area as a wetland. June 2006 1 J. S. Jones and Associates, Inc. The field delineation and data collection were completed on May 17, 2006. The wetland boundaries were marked with consecutively numbered orange flagging. Wetland boundaries will be surveyed prior to any development proposal. Approximate location of wetland boundaries, buffers, and sample locations are presented on the attached wetland sketch. The assessment included a review of the USDA Soil Conservation Service's Soil Survey of King County Area, Washington (Snyder, et. al., 1973). Wetlands were rated and wetland functions were assessed using the Washington State Wetland Rating System for Western Washington developed by the Department of Ecology. 4.0 General Site Description The site is a 1.04-acre parcel with a forested plant community. The parcel is approximately 454.1 feet long and 105.9 feet wide. The property is bordered by undeveloped forested parcel to the north and south, Southwest Dash Point Road is to the west and 28'h Avenue Southwest is to the east. The site is in a slope greater than 15% from east to west. The plant community is dominated by big -leaf maple, red alder, Douglas fir, vine maple, Indian plum, stinging nettle, lady fern, sword fern, slough sedge, skunk cabbage, salmonberry, Himalayan blackberry. The site is in the drainage basin of Dumas Bay in the Central Puget Sound watershed and WRIA 9 (Duwamish-Green). 5.0 Vegetation 5.1 Vegetation Methodology Hydrophytic vegetation has adaptations that allow these species to survive in saturated or inundated environments. These environments are classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, 1979). The probability of species being found in wetland environments has been determined by the U.S. Fish and Wildlife Service in the National List of Vascular Species that Occur in Wetlands: 1996 National Summary (USFWS, 1996). An indicator status was applied to each species according to its probability of occurring in wetlands (see Table 1.0). Vegetation data was recorded at four sample locations distributed across the property with at least one sample location in each plant community. At each sample location, the dominant species were assessed by indicator status to determine if the plant community was predominantly hydrophytic. Rules for determining dominant species were established in the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). Dominants were determined using the 50/20 rule. Using this rule, percent cover was added by order of descending cover until 50% cover was reached. These species were considered dominants. The next most common species was also included as a dominant if it had over 20% cover. Species with less than 5% cover were not considered dominant species. Table 1.0 Plant Indicator Status Indicator CateLrory Symbol Occurrence in Wetlands Obligate Wetland OBL > 99% Facultative Wetland FACW 67-99% Facultative FAC 34-67% Facultative Upland FACU 1-33% Upland UPL < 1 % Note: FACW, FAC, and FACU have + and — values to represent species near the wetter end of the spectrum (+) and the drier end of the spectrum (-) (USFWS, 1996). June 2006 2 J. S. Jones and Associates, Inc. 5.2 Vegetation Results At sample location 1 (SL-1), the plant community is dominated by big -leaf maple (Acer macrophyllum, FACU), salmonberry (Rubus spectabilis, FAC+), skunk cabbage (Lysichiton americanum, OBL), common horsetail (Equisitum arvense, FACW), lady fern (Athyrium filix- femina, FAC+) and unidentified grasses (Graminaea sp., FAC). Grasses in western Washington are typically tolerant of wet conditions, therefore the unidentified grasses are assumed to be FAC. The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW, or OBL (see Table 2 and attached data forms). At SL-2, the plant community is dominated by salmonberry (Rubus spectabilis, FAC+), red osier dogwood (Corylus cornuta, FACW), Himalayan blackberry (Rubus armeniacus, FACU), vine maple (Acer circinatum, FAC-), and -common horsetail, (Ranunculus repens, FACW). The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW, or OBL (see Table 2 and attached data forms). At SL-3, the plant community is dominated by big -leaf maple (Acer macrophyllum, FACU), salmonberry (Rubus spectabilis, FAC+), skunk cabbage (Lysichiton americanum, OBL), common horsetail (Ranunculus repens, FACW), Himalayan blackberry (Rubus armeniacus, FACU), spreading wood fern (Dryopteris austriaca, FACW), and unidentified grasses (Graminaea sp.). Grasses in western Washington are typically tolerant of wet conditions, therefore the unidentified grasses are assumed to be FAC. The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW or OBL (see Table 2 and attached data forms). At SL-4, the plant community is dominated by Indian plum (Oemleria cerasiformis, FACU), skunk cabbage (Lysichiton americanum, OBL), salmonberry (Rubus spectabilis, FAC+), lady fern (Athyrium filix femina, FAC+), and Himalayan blackberry (Rubus armeniacus, FACU). The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW or OBL (see Table 2 and attached data forms). June 2006 J. S. Jones and Associates, Inc.

Areas that are saturated between 5% and 12.5% of the growing season may or may not be wetlands. The growing season can either be defined by the number of frost -free days (temperatures above 28017), or the period during which the soil temperature at a depth of 19.7 inches is above biological zero (41 °F). The presence of wetland hydrology was determined at each sample location by evaluating a variety of direct and indirect indicators, consistent with the Washington State Wetlands Identification and Delineation Manual and the U.S Army Corps of Engineers Wetland Delineation Manual. In addition to direct visual observation of inundation or saturation, secondary hydrologic indicators were used to infer wetland hydrology. Secondary indicators include oxidized channels (rhizospheres) associated with living roots and rhizomes, water marks on vegetation or fixed objects, drift lines, water -borne sediment deposits, water stained leaves, surface scoured areas, wetland drainage patterns, morphological plant adaptations, and hydric soil characteristics. Another secondary indicator is the FAC-Neutral test, which is used to determine if the plant community is hydrophytic when all species with FAC indicator status are disregarded. June 2006 4 J. S. Jones and Associates, Inc. 6.2 Hydrology Results SL-1 has wetland hydrology. The soil profile is saturated to the surface. There is surface water seepage flow from the upper slope. SL-2 has wetland hydrology. The soil profile is saturated to the surface. There is surface water seepage flow from the upper slope. SL-3 has wetland hydrology. The soil profile is saturated to the surface. There is surface water seepage flow from the upper slope. SL-4 has wetland hydrology. The soil profile is saturated to the surface. There is surface water seepage flow from the upper slope. 7.0 Soils 7.1 Soils Methodology Hydric soils are soils that are "saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (COE, 1987)." They are either organic soils (peats and mucks), or are mineral soils that are saturated long enough to produce soil properties associated with a reducing environment. These soils have hydric characteristics such as a reduced matrix (a matrix that changes color when exposed to air), redox depletions (gleying), or redox concentrations (mottles). Soils were visually assessed for hydric characteristics and organic content in an 18-inch soil pit at each sample location. In Washington State, soil color is the main indicator used to determine if a soil is considered hydric. Soil color immediately below the "A" horizon or at a depth of 10 inches below ground surface was determined using Munsell Soil Color Charts (MacBeth, 1990). Soils that had a one-chroma matrix or a two-chroma matrix with mottles were determined to be hydric. 7.2 Soil Series The on -site soils were mapped by the USDA Soil Conservation Service (SCS) as Indianola fine sand (InQ (see Figure 2). "The Indianola series is made up of somewhat excessively drained soils that formed under conifers in sandy, recessional, stratified glacial drift". "In a representative profile, the upper 30 inches is brown, dark yellowish -brown, and light olive - brown loamy fine sand"(Snyder, et. al., 1973). June 2006 5 J. S. Jones and Associates, Inc. Figure 2. Soil Map of Project Site (King County Soil Survey Sheet 15, Plate 04). 7.3 Soils Results The soil at SL-1 is a hydric Indianola fine sandy loam. From 0 to 8 inches, the soil is a very dark brown (1 OYR 2/2) Indianola fine sandy loam. From 8 to 14 inches, the soil is a very dark grayish brown (10YR 3/2) Indianola fine sandy loam (see Table 3). The soil is hydric because it has a two-chroma matrix with sulfidic odor immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). The soil at SL-2 is a hydric Indianola fine sandy loam. From 0 to 10 inches, the soil is a very dark brown (1 OYR 2/2) Indianola fine sandy loam. From 10 to 18+ inches, the soil is a dark grayish brown (1 OYR 4/2) Indianola fine sandy loam with common, medium, prominent yellowish brown (1 OYR 5/6) mottles (see Table 3). The soil is hydric because it has a two- chroma matrix with mottles immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). The soil at SL-3 is a hydric Indianola fine sandy loam. From 0 to 10 inches, the soil is a black (1 OYR 2/1) Indianola fine sandy loam. From 10 to 16 inches, the soil is a very dark brown (I OYR 2/2) Indianola fine sandy loam (see Table 3). The soil is hydric because it has a two- chroma matrix with sulfidic odor immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). June 2006 6 J. S. Jones and Associates, Inc. The soil at SL-4 is a hydric Indianola fine sandy loam. From 0 to 8 inches, the soil is a very dark brown (I OYR 2/2) Indianola fine sandy loam. From 8 to 16 inches, the soil is a dark grayish brown (1 OYR 4/2) Indianola fine sandy loam with common, medium, prominent, yellowish brown (1 OYR 5/6) mottles (see Table 3). The soil is hydric because it has a two-chroma matrix with mottles immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997).

The wetland is part of a wetland system adjacent to the subject property. Its hydrogeomorphic classification is a slope wetland. The main sources of wetland hydrology are precipitation, surface water inflows, and seepage. The soils are a hydric one to two chroma matrix Indianola fine sandy loam with sulfidic odor or common, medium-sized, prominent mottles. The wetland has palustrine scrub shrub (PSS) and palustrine forested (PFO) classes of vegetation (Cowardin, 1979). The plant community is dominated by skunk cabbage, slough sedge, common horsetail, unidentified grass, lady fern, spreading wood fern, stinging nettle, salmonberry, vine maple, red -osier dogwood, red alder, and Indian plum. The wetland has a total function score of 45 and is rated a Category III wetland (see Table 4). The wetland has a score of 25 points for habitat functions. According to Section 22-1357 (b) (3) of the Federal Way City Code (FWCC), "Category III wetlands shall have a standard buffer width of 50 feet for wetlands that are greater than 10,000 square feet in area". The remainder of the subject property is upland. Originally, this project include the adjoining parcel to the north and south, but was split into separate reports. Upland sample locations for this wetland were collected but fell on adjoining properties. However, a non-hydrophytic plant community is present, dominated by big -leaf maple, Indian plum, Oregon grape, beaked hazelnut and sword fern. The soil is a non-hydric, two to four-chroma matrix Indianola fine sandy loam. June 2006 7 J. S. Jones and Associales, Inc. 9.0 Functional Assessment The wetland functions for the wetland system in the area were assessed using the 2004 DOE Wetland Rating System for Western Washington. The rating system scores the wetland based on characteristics that contribute to habitat, hydrologic and water quality functions (see Table 4 and attached DOE Wetland Rating Forms). The wetland has potential to perform water quality functions because it has dense, woody, vegetation greater than one half of the wetland area that trap sediments and pollutants from surface runoff or groundwater. The wetland has an opportunity to improve water quality because untreated water from residential areas, parking lots, and roads drains into the wetland and downslope. The wetland has potential to perform hydrologic functions by reducing flooding and stream erosion downslope. The dense, uncut, rigid vegetation that covers greater than 1/2 of the wetland will help in reducing water velocity during peak flows that would otherwise flow directly into properties downstream. The wetland has opportunity to reduce the impact of flooding because it helps protect downstream properties during storm events. The wetland has potential to provide habitat functions for wildlife because it has three types of vegetation classes with a moderate interspersion of plant species. There are special habitat features such as large, downed woody debris, standing snags, and thin -stemmed vegetation or woody branches that can be used by wildlife. The wetland has opportunity to provide habitat for wildlife because the condition of the wetland buffer is relatively undisturbed and the corridors and connections to the larger habitat in the watershed are relatively undisturbed and unbroken.

S. Jones and Associates, Inc. 10.0 Impacts Proposed impacts are yet to be determined. A site plan has not been developed. Impacts will not exceed those required by the Federal Way City Code (FWCC). 11.0 Authority This wetland determination is in accordance with Section 404 of the Clean Water Act, the objective of which is to "maintain and restore the chemical, physical, and biological integrity of the waters of the United States (DOE, 1997)." Wetlands are "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (EPA, 40 CFR 230.3 and CE, 33 CFR 328.3)." 12.0 Limitations Wetland determinations and delineations are not final until approved by regulatory agencies and/or local jurisdictions. J. S. Jones and Associates, Inc. does not guarantee acceptance or approval by regulatory agencies, or that any intended use will be achieved. 13.0 References Cowardin, Lewis M. 1979.

If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. - :a5_ SP1. Has the wetland been documented as a habitat for any Federally listed Threatened or Endangered plant or animal species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the 2ppropriate state or federal database. SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered plant or animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. SP3. Does the wetland contain individuals of Priority species listed by the WDFW for the state? ✓ SP4. Does the wetland have a local significance in addition to its functions? For / example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form — western Washington 2 August 2004 Classification of Vegetated Wetlands for Western Washington Wetland Name: Date: 1 e-�e water levels in the wetland usually controlled by tides (i.e. except during floods)? NO,l go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (pans per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) 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 rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. Is the topography within the wetland flat and precipitation is only source (>90%) of water to it. t' NO'! go to 3 YES — The wetland class is Fiats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water (without any vegetation on the surface) where at least 20 acres (8 ha) are permanently inundated (ponded or flooded); At least 30% of the open water area is deeper than 6.5 ft (2 m)? No— gogo to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the wetland 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? 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 <3ft diamet . nd less than 1 foot deep). NO - go to 5 'YES he wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average, to answer "yes. " The wetland can contain depressions that are filled with water when the river is nat-fl�ding. NO -'go to 6 YES — The wetland class is Riverine Wetland Rating Form —western Washington 3 August 2004 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present, is higher than the interior of the wedand. go to 7 YES — The wetland class is Depressional 7. Is the wetland located in a very flat area with no obvious depression and no stream or river running through it and providing water. The wetland seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO L go to 8 YES -- The wetland class is Depressional 8. Your wetland seems to be difficult to classify. 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. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class. If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Does the wetland have more than 70% cover of mosses at ground level, AND other plants, if present, consist of the "bog" species I isted in Table 3 as a significant component of the vegetation (more than 30% of the total shrub and herbaceous cover consists of species in Table 3)? Yes — Is a bog for purpose of rating No - go to Q. 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog. 3. Is the wetland forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine, WITH any of the species (or combination of species) on the bog species plant list in Table 3 as a significant component of the ground cover (> 30% coverage of the total shrub/herbaceous cover)? 4.

With this request for additional information, the 90-day maximum review time frame is suspended, and it will be restarted within 14 days of the date of your complete response to this request. The following items are based on an initial technical review of the application by City staff during completeness review. Planning, David Lee, 253-835-2622, david.lee@cityoffederalway.com 1. Please amend the following SEPA checklist sections: a. Section B. Lb. "What is the steepest slope on the site?" The applicant indicated that the steepest slope is greater than 30%. Please indicate more accurately the steepest slope's gradient. Additionally, please indicate on the site plan where steep slopes in excess of 40% exist. Mr 'Adzhigirey August 4, 2008 Page 2 b. Section 3.a.3 "Estimate the amount of fill and dredge material..." The applicant indicated that the fill amount and source of fill was unknown. Please provide a best estimate of the amount of fill/dredge material to be used within surface water areas and wetland areas. Additionally, please indicate the source of the fill material (Onsite? Offsite?). Please note that if steep slopes in excess of 40% are indicated on the site plan and development activity occurs within 25 feet of the tip or toe of the slope, a soils report prepared by a qualified professional engineer will be required per FWCC Section 22-1286. The soils report must contain information that describes how the proposed development will impact each of the following on the subject property and nearby properties: a. Slope stability, landslide hazard, and sloughing. b. Seismic hazards. C. Groundwater. d. Seeps, springs, and other surface waters. e. Existing vegetation. f. Recommended foundation design and optimal location for roadway improvements. g. Recommended methods for mitigating identified impacts and a description of how these mitigating measures may impact adjacent properties. h. Any other information the city determines is reasonably necessary to evaluate the proposal. 2. The wetland reports prepared by IS Jones & Associates, Inc. do not specifically address the potential future site development of either the installation of water/sewer lines or the potential development of a single-family home. Impacts of, at the very least, the water/sewer lines must be assessed and reported in this document. Additionally, the report must also demonstrate that the improvements within the wetland and its buffer: a. Will not adversely affect water quality. b. Will not adversely affect the existing quality of the wetland's or buffer's wildlife habitat. c. Will not adversely affect drainage or stormwater retention capabilities. d. Will not lead to unstable earth conditions nor create erosion hazards. e. Will not result in no net loss of wetland area, function, or value. Additionally, the report should also contain mitigation measures for any impacts that this proposed project may create. The mitigation plan must include: a. Environmental goals and objectives. b. Performance standards. c. Detailed construction plans. d. Timing. e. Monitoring program for a minimum of five years. f. Contingency plan. g. Subject to the applicant's election of timing alternatives, a performance and maintenance bond in an amount of 120% of the costs of implementing the mitigation plan or the contingency plan, whichever is greater. As drawn on the plans, the project proposes to traverse both the Category III wetland and its buffer on the northeast corner of the site. Additionally, there are several points of intrusion in the wetland buffer along the southern edge of the wetland buffer. Although the SEPA checklist is an initial component of the review process, the actual approval process of the proposed wetland intrusions and wetland buffer intrusions must be administered through a Land Use Process IV Hearing Examiner. 08-101266 Doc. I.D 46001 Mr. Adzhigirey August 4, 2008 Page 3 The application does not qualify for the exemption listed in FWCC Sec. 22-1359(c) Essential public facilities, public utilities, and other public improvements' due to the fact that this is a privately initiated action and the proposal calls for the intrusion into the actual wetland. FWCC Section 22- 1359(c) was intended for the use of essential public utilities to traverse only wetland buffers to serve the public. The applicant must submit a separate Land Use Process IV application. Additionally, per FWCC Section 22-1359(f) the applicant must prove that: a. It will not adversely affect water quality. b. It will not adversely affect the existing quality of the wetland's or buffer's wildlife habitat. c. It will not adversely affect drainage or stormwater retention capabilities. d. It will not lead to unstable earth conditions nor create erosion hazards. e. It will not be materially detrimental to any other property in the area of the subject property nor to the city as a whole, including the loss of open space. f. It will result in no net loss of wetland area, function, or value. g. The project is in the best interest of the public health, safety, or welfare. h. The applicant has demonstrated sufficient scientific expertise and supervisory capability to carry out the project. i. The applicant is committed to monitoring the project and to making corrections if the project fails to meet projected goals. 4. The application is specifically for the installation of the water/sewer lines within the regulated wetland and buffer. However, the "potential development area" on Lot 5 (Shramovych) is well within the 50-foot wetland buffer. It may be beneficial to the applicant to specify the buildable areas, potential building footprint, and site improvements on the site plan of all lots. If future development occurs on the lots without it being considered as part of this application, any future development activities would be subject to new Land Use Processes and SEPA checklist review. 5. Another set of addressed/stamped envelopes must be submitted to the City in the event of a Determination of Nonsignificance. The applicant turned in only one set of stamped/addressed envelopes at submittal. 6. Please be aware that the project will require the use of a third party consultant to review the wetland assessment by JS Jones & Associates, Inc. on behalf of the City as the City does not have a wetland biologist on staff. The City's wetland consultant will provide a scope of work estimate, which will be forwarded to the applicant once the information requested has been submitted. Please note that once all missing technical information has been resubmitted, the City will notify the applicant as expediently as possible for the cost of third party review of the wetland report as provided for by FWCC Section 22-1243. Public Works Development Services Public Works Development Services comments will follow this letter within two weeks. 1 The director of community development may permit the placement of an essential public facility, public utility or other public improvements in a 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 system efficiency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. 08-101266 Doc I.D. 46001 Mr. Adzhigirey August 4, 2008 Page 4 CLOSING Your project will be put on "Hold" until the above requested items, INCLUDING the Land Use Process IV application have been submitted. After receipt of the requested information, the Department will review your resubmittal within 14 days and notify you if any information is still needed. As revisions to the plans are submitted, additional review may identify further revisions to the plans to meet applicable codes and regulations. Pursuant to FWCC Section 22-34, if an applicant fails to provide additional information to the City within 180 days of being notified that such information is requested, the application shall be deemed null and void and the City shall have no duty to process, review, or issue any decisions with respect to such an application. Please contact me at 253-835-2622 or david.lee _ ciiyoffederalway.com if you have any questions or need any assistance. I look forward to working with you on this project.
