Project Location Map ERC Report 10-008.doc City of Renton Deportment of Comm unit O Economic Development WONDERLAND ESTATES UTILITY REPLA ENT Report of May 17, 2010 PART ONE: PROJECT DESCRIPTION / BACKGROUND c vironmentaf Review Committee Report WAl0-008, ECF, CAR Page 2 of9 Wonderland Estates is located at 14645 SE Renton-Maple Valley Road and has been a developed manufactured home park (MHP) since the early 1960's. The site contains 108 spaces for manufactured homes each with parking for two vehicles. At this time, the park is not completely full although, at maximum capacity, the site would have a gross density of 8.8 dwelling units per acre. Currently Wonderland Estates is a 55+ community that is bordered by New Life Church and a single-family home to the east, a large single-family residential subdivision (Pioneer Place) to the west, vacant property to the south and southwest, and across Maple Valley Road is the Cedar River Trail and King County. Currently the site contains an office and recreational hall, laundry room, and storage shed all of which are to be maintained with the exception of the laundry room, which would be demolished. The MHP gains access at one signalized ingress/egress point along Renton-Maple Valley Road. The site is zoned Residential Manufactured Home (RMH) and is located in the Residential Medium Density (RMD) land use designation. The applicants are requesting SEPA environmental review for stormwater and utility improvements, and are not proposing any changes to the existing MHP with the exception of the removal of the laundry room. All 108 units would remain, all parking would be maintained, roads would be repaved, ingress/egress would remain and any landscaping that is disturbed as a result of the utility improvements would be replaced. The City of Renton's Critical Areas Maps indicate that the subject site is within the vicinity of seismic hazards, landslide hazards, erosion hazards, protected slopes, flood hazards, wetlands, and a Class 2 stream. The applicant provided a letter from The Watershed Company, dated November 11, 2009, in which, they identified a Category 3 wetland on the subject site. Madsen Creek's main channel is located near the northeast corner of the subject site (but is not located on the site) and the over flow channel of Madsen Creek runs along the east property line of the site. The City's Sensitive Areas Maps also identify the over flow channel of Madsen Creek as a Class 2 stream as well as the stream itself. The proposed project would not result in impacts to any of the identified critical area in or around the subject site with the exemption of the Wetland. As such, the applicant has also requested a Critical Areas Exemption for the re-pavement of the existing road and replacement of a storm drainage line that are located within the wetland buffer. The site is also located in a flood hazard area, Zone A per FIRM Map Number 53033C0984K. No impacts are proposed to the flood hazard area, although a sewer pipe would need to be connected to an existing public sewer manhole, which is located within the flood zone. The current storm drainage conditions at the subject site result in localized flooding. Madsen Creek floods on to the site impacting roads and some of the structures in the north end of the site and Pioneer Place, the adjacent neighborhood. One of the primary reasons for the proposed project is to alleviate flooding on the property due to flooding of Madsen Creek. Additional benefits of the applicant's proposal includes a reduction to the potential flooding in Pioneer Place to the west and Madsen Creek downstream of the site. Overall the applicant is proposing to upgrade the stormwater management facilities at the site in an effort to reduce and control the impact of stormwater runoff to the site and off-site flooding. A new pumping system with appropriate storage capacity would be provided to mitigate on-site flooding. The current discharge location is into Madsen Creek via a pump system. This discharge location falls within the 100 year flood hazard area. The project proposes to maintain the current drainage configuration of pumping to Madsen Creek. The northwest corner of the site would be used to create flood storage volume and reduce the potential for flooding of on- site structures.

Following the completion of the new utilities the road would be reconstructed and resurfaced. Although the applicant has proposed to narrow the internal roads as follows: Pine Drive and Oak Drive by 6-feet (from 30-feet to 24-feet) and Maple Drive by 5-feet (from 33-feet to 28-feet) resulting in a overall reduction of impervious surfaces within the development. To further reduce impervious surfaces the applicants have proposed the removal of an obsolete tennis court that is located in the south section of the site. As a result of the proposed project approximately 12,000 cubic yards of cut and 11,850 cubic yards of fill would be required. I PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The City of Renton's Critical Areas Maps indicate that the subject site is within the vicinity of many geological hazards including, seismic hazards, landslide hazards, erosion hazards, and protected slopes. As such, the applicant submitted a "Geotechnical Engineering Design Study", prepared by Hart Crowser, dated February 17, 2010. Pursuant to the Geotechnical Study, the developed portion of the site is fairly flat sloping slightly downward to the north. The surface elevations range from about 120 feet mean sea level (MSL) at the south end to 100 feet MSL in the north end near SR-169. There is an undeveloped hill in the extreme southwest corner of the site that slopes steeply upward toward the southwest. The landslide and erosion hazards identified on the City's Critical Areas Maps are associated with the hill located in the southwest corner of the site. This hill is considered to be a protected slope pursuant to Renton Municipal Code. The proposed project is entirely located within the developed portion of the site; therefore, impacts related to the steep slopes are not anticipated as a result of the subject project. Pursuant to the provided geotechnical study the site generally contains very loose to medium dense alluvial soils from the ground surface downward. The materials primarily consist of silt, sand, gravel and combinations thereof. Furthermore, the report indicated that the loose, soft or medium dense soils are not suitable for direct support of pavement sections, on-grade utilities, or structural fill in their present condition. These soils would need to be compacted in place to a dense condition or removed and replaced with structural fill to provide sufficient support for the proposed improvements. ERC Report 10-008.doc City of Renton Department of Cammunit Economic Development WONDERLAND ESTATES UTILITY REPLA ENT Report of May 17, 2010 vironmental Review Committee Report LUAl0-008, ECF, CAR Page 5 of9 The Geotechnical Study indicated that the groundwater was encountered at depths of 2.5 feet to S feet below the ground surface. Additionally, the Study evaluated potential seismically induced geotechnical hazards including liquefaction, surface rupture, lateral spreading and landslides. The report concluded that the potential for surface rupture, lateral spreading and landslides were very small and did not warrant special geotechnical design considerations. Although the Study concluded that the subject site was susceptible to liquefaction because a significant portion of the site soils are in a loose to medium dense condition and below the water level; resulting is susceptibility to significant settlement of surface pavement, catch basins, manholes, buried pipelines, and other structures that are supported above the liquefiable soils. The report recommends that the design considers the potential for differential settlement. Furthermore, the Geotechnical Study provides conclusions and recommendations regarding the geotechnical aspects of design and construction including but not limited to site preparation, pavement design, curtain drain design, site utilities, structural fill selection, placement and compaction, and general construction considerations. As such, staff recommends a mitigation measure that the applicant comply with the recommendations included within the "Geotechnical Engineering Design Study", prepared by Hart Crowser, dated February 17, 2010. Approximately 23,850 cubic yards of cumulative grading will occur on the site with the proposed development. The proposed stormwater detention pond at the northwest property corner would be excavated in addition to utility line trenches. Due to the erosion potential of the subject site, staff recommends a mitigation measure that Temporary Erosion Control shall be installed and maintained to the satisfaction of the representative of the Development Services Division for the duration of the project and weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the Public Works Inspector and Certification ofthe installation, maintenance and proper removal ofthe erosion control facilities is required prior to Temporary Certificate of Occupancy. Mitigation Measures: 1. The applicant shall comply with the recommendations included within the "Geotechnical Engineering Design Study", prepared by Hart Crowser, dated February 17, 2010. 2. Temporary Erosion Control shall be installed and maintained to the satisfaction of the representative of the Development Services Division for the duration of the project and weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the Public Works Inspector and certification of the installation, maintenance and proper removal of the erosion control facilities is required prior to release of maintenance bond. Nexus: SEPA Environmental Regulations 2. Water a. Wetland, Streams, Lakes Impacts: The applicant provided a letter from The Watershed Company, dated November 11, 2009 addressing Wonderland Estates environmental and permitting review. Pursuant to this letter and the City's Critical Areas maps the following streams have been identified near the subject site. Madsen Creek, a Class 2 stream, flows out of an off-site ravine into a sedimentation pond located south of the subject property. This pond has two outlets; the original stream channel which flows east then north ERC Report 10-008.doc City of Renton Department of Community --conomic Development WONDERLAND ESTATES UTILITY REPLA, 'NT Report of May 17, 2010 vironmental Review Committee Report LUAl0-008, ECF, CAR Page 6 of9 eventually bending west to run parallel to SR-169 and a high-flow bypass channel that flows parallel to the eastern property line of the subject site. The City's Critical Areas maps identify both the main stream channel and the high-flow bypass as a Class 2 stream. Comments were received from King County Waste Water Treatment Division, indicating that the Madsen Creek Interceptor is located near the subject project. Because the subject project may have impacts on this existing, facility staff recommends as a mitigation measure that construction drawings for the project are submitted to the Asset Management section of King County, for review during project design development so the King County staff can assess project impacts. The Watershed letter also indicates that a Category 3 wetland is located at the base of the sloped, forested area in the southwest property corner. The wetland has been characterized as a slope-type wetland but was not delineated by the Watershed Company. A delineation of the subject wetland was completed by Raedeke Associates in 2006, when the subject property was located in King County. The applicants have utilized the 2006 delineation to identify any impacts to the wetland and/or its buffer as a result of the subject project. As proposed, no impacts to the streams or the wetlands would result from the subject proposal; although, minor impacts would occur to the 25-foot wetland buffer. Under current conditions a portion of Oak Drive and Birch Drive are located within the 25-foot wetland buffer area, along with a storm drain and pipe. As a part of the subject proposal, the applicant would be resurfacing the existing internal road system and replacing the storm drainage system. The proposed improvements would result in minor impacts to the wetland buffer including 1,680 square feet resurfacing of Oak Drive and Birch Drive and approximately 29 liner feet of storm drainage pipe replacement. RMC 4-3-0SOC.5.e.ii exempts normal and routine maintenance, operation and repair of existing streets, roads, rights-of-way and associated appurtenances, facilities and utilities where no alteration or additional fill materials will be placed other than the minimum alteration and/or fill needed to restore those facilities to meet established safety standards. The applicant has requested a Critical Areas Exemption for the work to be performed within the buffer of the wetland, see Exhibit 16. Although, normal maintenance and repair are exempt activities within a wetland buffer, temporary impact could occur to the buffer beyond the existing limits of the roadways, due to construction activity. As such, staff recommends a mitigation measure that any vegetation or soil disturbance that occurs as a result of the construction activity is restored and re-vegetated with native plants following construction. When buffer restoration is complete, the applicant shall contact the Current Planning Project Manager for an inspection prior to construction permit finalization. Mitigation Measures: 1. Construction drawings for the Wonderland Estates Utility Replacement project shall be submitted to King County's Asset management section for review during project design development so that King County staff can assess project impacts. The drawings shall be sent to Bob Isaac, Local Public Agency Administrator, King County WTD Asset Management, 201 South Jackson Street, KSC-NR- 0508, Seattle, WA 98104. 2. Any vegetation or soil disturbance that occurs in the wetland buffer, as a result of construction activity shall be restored and re-vegetated with native plants following construction. When the wetland buffer restoration is complete, the applicant shall contact the Current Planning Project Manager for an inspection prior to construction permit finalization.

Storm Water ERC Report 10-008.doc City of Renton Deportment of Community ·conomic Development WONDERLAND ESTATES UTILITY REPLA1 :NT Report of May 17, 2010 ~ vironmental Review Committee Report LUAl0-008, ECF, CAR Page 7 of9 Impacts: The applicant provided a draft Technical Information Report (TIR) prepared by Huitt-Zullars, dated April 9, 2010. Pursuant to the TIR, the on-site stormwater generally flows south to north/northwest toward SR-169 and the northwest corner ofthe site. Although the development of Pioneer Place (to the west) and alterations to SR-169 have changed the topography in the vicinity of the subject site, resulting in the need to pump runoff from the site. The current on-site drainage system collects stormwater runoff by gravity flow in a pipe network and pumps low flows to Madsen Creek. The TIR indicates that during high runoff events, the two existing pumps are incapable of matching peak runoff rates and runoff ponds in the northwest portion of the site before discharging to the west, which at one time was the natural drainage pattern in the area. The current condition of the roadside drainage swale located near the northwest corner of the site prevents efficient discharge at this location, therefore runoff floods onto the adjacent property (Pioneer Place), where homes are impacted before runoff enters the Pioneer Place development's drainage system. Furthermore, Madsen Creek floods onto the site at the location of the current pump discharge, impacting roads and some of the structures in the north end of the site, and Pioneer Place adjacent to the site. During Madsen Creek flooding events, the existing storm water pumping facilities re-circulate the runoff back onto the site. Under current conditions, the two available discharge points (Madsen Creek and the roadside swale) are inadequate to prevent flooding of the site and of adjacent properties downstream. One of the primary reasons for the proposed project is to alleviate flooding on the property due to flooding of Madsen Creek. Additional benefits of the applicant's proposal includes a reduction to the potential flooding in Pioneer Place to the west of the site. Overall, the applicant is proposing to upgrade the stormwater management facilities at the site in an effort to reduce and control the impact of stormwater runoff to the site and off-site flooding. The applicant is proposing to maintain the current drainage configuration of pumping to Madsen Creek. As such, the project would maintain the existing discharge rates and volumes to each drainage system. In addition to replacing the pumps that applicant has proposed to construct a flood storage, drainage ditch in the northwest corner of the site. This ditch would be used to reduce the potential of flooding on-site structures. Pursuant to the TIR this facility would not change flow characteristics of the existing site with the exception of replacing sheet flow with pipe flow over a short distance. Overall, the new storm water drainage facilities would improve the flooding problems on site and off site in Pioneer Place. Mitigation Measures: No further mitigation is required. Nexus: N/A 3. Environmental Health a. Noise Impacts: It is anticipated that short-term noise would occur during regular operation hours of construction. Construction times for this project shall be restricted to the hours between 7:00 a.m. and 8:00 p.m., Monday through Friday. Work on Saturdays shall be restricted to the hours between 9:00 a.m. and 8:00 p.m. and no work shall be permitted on Sundays. Mitigation Measures: No further mitigation is required. Nexus: N/A 4. Historic and Cultural Preservation Impacts: Historically the Cedar River has meandered downstream in the Renton-Maple Valley area across the width of the river valley. Furthermore, developments within the vicinity of the Cedar River ERC Report 10-008.doc City of Renton Department af Community --conamic Development WONDERLAND ESTATES UTILITY REPLA NT Report of May 17, 2010 -vironmental Review Committee Report LUAl0-008, ECF, CAR Page 8 of 9 are more likely to be sites where significant historic and/or cultural resources would be found, and the subject development has indicated that site grading would be conducted. Therefore, staff recommends a mitigation measure that requires the applicant and/or developer to stop work and immediately notify the City of Renton planning department, concerned Tribes' cultural committees, and the Washington State Department of Archeological and Historic Preservation if any Native American grave(s} or archaeological/cultural resources (Indian artifacts} are found. Mitigation Measures: If any Native American grave(s} or archaeological/cultural resources (Indian artifacts} are found, all construction activity shall stop and the owner/developer shall immediately notify the City of Renton planning department, concerned Tribes' cultural committees, and the Washington State Department of Archeological and Historic Preservation at 360-586-3065. Nexus: SEPA Environmental Regulations 5. Transportation Impacts: During construction, the project is anticipated to have temporary impacts on vehicular movement throughout the internal street system. The applicant has provided a preliminary traffic control plant that indicates the MHP ingress and egress would be maintained during construction, as well as the signalized intersection with Renton-Maple Valley Road (SR-169). To ensure access is maintained to the resident's homes throughout the construction process, staff recommends a mitigation measure that the applicant submit a construction plan indicating haul routes and hours, construction hours, and a traffic control plan for approval by the City prior to construction permit issuance. Mitigation Measures: A construction plan indicating haul routes and hours, construction hours, and a traffic control plan shall be submitted for approval prior to any permit being issued.

After review of the new materials staff has identified some additional areas of concern as described below: 1. As proposed, additional. stormwater would be diverted from its currant drainage location of Madsen Creek into a new stream tributary identified in the provided TIR as "Stream A". Stream 'A' flows through the City's Ron Regis Park and eventually outfalls into the Cedar River. A Biological Impact Assessment Memo completed by the Watershed Company was provided in Appendix E of the TIR report. Within this Assessment, The Watershed Company indicates that no wetlands were observed along Stream A: The City believes this report is in error, because a wetland was identified in this area during the Cedar River Regional Park Master Plan process. The diversion of additional stormwater, to this wetland, may have adverse impact to the wetland hydrology. The additional. storm water runoff could result in an increase in the wetland size and/or value affectively increasing its buffer size and/or area. If the wetland changes in size and/or value it would have adverse impacts on the Cedar River Regional Park Master Plan and anticipated improvements for Ron Regis Park. Furthermore, the City has received grant funding for Ron Regis Park from the Recreation and Conservation Office (RCO) and the Federal Land a.nd Water Conservation; these grant funds require that particular improvements are made to the Park. Changes to the wetland or Stream 'A' may impact the City's ability to comply with the grant funding requirements. 2. Additionally the City is working with potential FEMA funds to rehabilitate the Elliot Spawning channel that was damaged in the 2006 and 2009 Cedar River flooding events. The Elliot Spawning channel is located just downstream of point F of Stream 'A', as Renton City Hall • 1055 South Grady Way • .Renton, Washington 98057. • rentonwa.gov Mr. Don Helling Apri I 2, 2010 Page 2 of3 • identified in the TIA. Any increase in Stream flows may affect the City's access to the site during construction as well as potentially impact the spawning channel itself. In addition to the above concerns, the City Stormwater Division has questions and/or concerns about the provided TIA. The following is a list of issues identified by the City's Stormwater Division: 1. The TIR states that discharging site runoff to the northwest corner of the site would alleviate flooding in Wonderland Estates and reduce some of the flooding potential in Lower Madsen Creek. The TIR does not quantify how much flooding would be reduced. It would seem that removing 3 cfs from the total tributary flow to Madsen Creek would have negligible improvement in the amount of on site flooding. 2. The Stormwater Division is confused with Table 3.1 on page 13. Under existing conditions for the 25-yr storm, Wonderland Estates contributes 4.52 CFS. Is this because the pumps do not have enough capacity to pump the on site runoff to Madsen Creek? What if the pumps were sized to discharge all the site runoff to Madsen Creek. What would be the amount of increased flooding that would occur at the northwest corner of the site? 3. Why is the proposed flow for the 25-yr event 3 cfs for Wonderland Estates in Table 3.1? One would think the proposed flow should be 4.52 cfs + 3.0 cfs or 7.52 cfs, which is the capacity of the conveyance system ofthe proposed discharge route. 4. The Stormwater Division doesn't understand how the existing water surface elevations for Stream A at points A, 8, C, D, E and F are higher than the proposed conditions. The proposal to divert additional flow to Stream 'A' will add 3 cfs for the 25-yr event; therefore, the water surface elevations must increase correspondingly. Table 3.2 shows the 25-yr design flow of 10.33 cfs for existing conditions and 8.81 cfs for proposed conditions. How can this be when additional flow is being diverted to Stream 'A'? 5. The project does not trigger flow control because the proposed improvements will not result in an increase in impervious surface; however, because Stream 'A' is located in an area with erodible soils, any increase in flow could result in erosion and subsequent degradation of water quality. To eliminate this condition, the proposal to divert flows would require that Stream 'A' be placed in a pipe all the way to the Cedar River. Constructing a pipe through a wetland is not allowed per City code. Code would require that the pipe be placed in an alignment that avoids the wetland. Placing Stream 'A' in a pipe would change the hydrology of the wetland by reducing the volume of tributary runoff and would require an analysis determine any impacts and appropriate mitigation. Finally, constructing the pipe near a sensitive area would involve federal, state and local permits. Mr. Don Helling April 2, 2010 Page 3 of 3 Based on the above-identified technical issue! and concerns the City requests that the applicant look at alternative drainage discharge locations that would not result in impacts to City Parks, grant funding, and spawning channel. At this time, your project has been placed "on hold" pending resolution of the drainage concerns and issues identified above. Please contact me at (425) 430-7314 if you have any questions or would like to schedule a meeting to discuss the identified project issues.

A we~and study was completed for the property, Including delineation of a large wetland adjacent to the Cedar River. Methods Wetland delineation was preformed according to the 1989 Federal Manual for Identifying and Oellneatlng Jurisdictional Wetlands. Vegetation, soils, and hydrology were examined. In order to make a determination of the presence of wetland, Indicators of hydrophytic vegetation, hydric soil, and wetland hydrology m1.1st be observed. Hydrophytic vegetation consists of a plant community in which more than 50% of the dominant species have a wetland indicator status (Reed, 1988) of facultative (FAC), facultative wetland (FACW), or obligate (OBL). Soil color In hand dug test pits was used as an indicator of hydric soil. A chroma of one, or of two in mottled soil, is considered indicatlve of hydric soil. Wetland hydrology is present when soil is saturated to the surface for at least one week during the growing season. Results A single wetland was identified on the site. The wetland boundary ro1.1ghly parallels the Cedar River, dividing the site Into upland on the south portion of the property, and wetland on the north portion. The wetland is forested, and includes a small beaver pond formed on Madsen Creek; this stream n.ms along the eastern property boundary. · YeQetaHon Vegetation of lhe south part of the site has been disturbed in the past, and now consists mainly of clumps of blackberries along wllh grasses and other weedy plants. Species present include Himalayan and evergreen blackberry, Scot's broom, bull and Canada thistle, buckhorn plantain, clover, Watson's willow-herb, common tansy, and grasses such as orchard grass, quackgrass, and bentgrass. These species do not constitute hydrophytic vegetation, as less than 50% of the dominant species have a wetland Indicator status of FAC, FACW, or OBL. At the southern property boundary, near the railroad right of way adjacent to Maple Valley Highway, some red alder trees form a line; a shrub thicket consisting of snowberry and Pacific ninebark borders a diteh next to the right of way. To the north, in the vicinity of the wetland bo1.1ndary, the dominant species Include Himalayan blackberry, evergreen blackberry, soft rush, reed canarygrass, field horsetail, bulrushes, creeping butlercup, and gro1.1nd ivy. In the forested portion of the wetland, a variety of plant species are present. In the overstory, the dominant trees are red alder, black cotlonwood, bigleaf maple, and western red cedar; several trees are dying due to flooding caused by beavers. PaciflC willow and English holly are also present. Understory species include snowberry, salmonberry, nootka rose, ninebark, reed canarygrass, piggyback, curty dock, buttercup, and bulrushes. Because more than 50% of these species have an Indicator status of FAC, FACW, or OBL, this plant community is considered hydrophytic. 1 The on·site soils have been mapped In the King County Soil Survey as Newberg silt loam, Puyallup fine sandy loam, and Riverwash. Of these soils, only Riverwash is considered hydric; the northern part of the site, along the Cedar River, was mapped as Riverwash. SOIi colors vary relatively little across the site. On the upland part of the site, the colors typically found were olive brown (2.5 Y 4/3) and brown (10 YR 4/3), primarily without mottles. Soll color within the wetland was generally dark grayish brown (2.5 Y 4/2) or very dark grayish brown (2.5 Y 312) with mottles. These colors meet the criterion for hydric soil. HydmJogy Secause field work was conducted in December, soils throughout the site were damp to saturated. The transition between damp and saturated soils, moreover, was a fairly reliable indicator of the wetland boundary. That Is, at the time of observation, soil within the wetland was nearly all saturated, meeting the criterion for wetland hydrology. Ponded water was observed in many areas, Including a small beaver pond. Madsen Creek constitutes another hydrologlc feature of the site. The stream was relocated onto the site by King County Surface Water Management. In its current channel, it enters the property at the southeast corner, follows the eastern property boundary, then flows through the wetland to the Cedar River. The stream was not field-Hagged, as there is no wetland fringe on the edges of the stream. In addition, a small drainage with wetland characteristics Is present on the western property boundary. This drainage was delineated and field-flagged as wetland. The hydrology of the area Is likely to be changing due to the activity of beavers. A dam has been constructed on Madsen Creek, creating a small pond, and recent activity is evident. Because of the presence of beavers, the location of the wetland boundary may change in the future. summary of Existing Qonditjons The site of the proposed Cedar River Regional Park was screened for the presence of wetlands. A single wetland was Identified and field-flagged; this wetland encompasses most of the northern part of the site, adjacent to the Cedar River. No other wetlands are present on the property. The values of the delineated wetland include wildlife habitat, water quality, and flood control. Due to the proximity of the Cedar River, the wetland is expected to play a significant role in attenuation of floods in the area. It also serves as a filter to improve water quality. Moreover, the site has tremendous value for wildlife, particularly the northern portion of the site which Includes the forested wetland. With the combination of the presence of the river, mixed forest, shrub, open water {pond), and grassland habitat, the site provides not only cf!Verse habitat types but a large amount of edge habitat. Edges are important for wildlife as they support a particularly diverse plant community within a short distance. The site can be expected to support a variety of bird species, including songbirds, ground birds, 2 woodpeckers, and raptors, as well as small mammals, deer, furbearers, reptiles, and amphibians. Bird species observed Include the black-capped chickadee, American goldfinch, rufous-sided towhee, song sparrow, Lincoln's sparrow, purple finch, varied thrush, golden- crowned kinglet, ruby-crowned kinglet, American robin, winter wren, Northern flicker, downy woodpecker, California quail, red-tailed hawk, sharp-shinned hawk, American kestrel, mallard, goldeneye, common merganser, and great blue heron. Other wildlife detected include the beaver, raccoon, and black-tailed deer. Under the Renton Wetlands Management Ordinance, the wetland is considered a Category I wetland, due to its size (approximately 21.5 acres) and the presence of three vegetation classes, one of which Is open water. Because the wetland will be preserved as the site Is developed, wildlife will continue to use the wetland. Moreover, use of the property as a park will enhance public access to the area, thereby contributing to enjoyment of the resource. 3 Common Name ovecstocvacees; red alder big leaf maple English holly black cottonwood Pacific willow sitka wliiow westem red cedar ShrubsNloes; butterfly bush red osier dogwood nlnebark nootka rose Himalayan blackberry evergreen blackberry blackcap raspberry thimbleberry salmonberry traliing blackberry snowberry Groundr;nver quackgrass bentgrass lady fem bull thistle Canada thlstle morning glory Scotch broom orchard grass foxglove Watson's willow herb field horsetail scouring rush lescue large-leaf avens wild geranium ground Ivy English ivy St. John's wort soft rush toad rush duckWeed reed canary grass Table I: Plant Specie$ Observed Scientific Name A/nus rubra Acer macrophyllum /lex aquifolium Populus trichocarpa Sa/Ix lasiandra Salix sitchensis Thuja plicata Buadleia davidii Cornus stolon/fera Physocarpus capitatus Rosa nutka.na Rubus discolor Rubus /acinatus Rubus /eucodermis Rubus parviflorus Rubus spe&tabilis Rvbus ursinus Symphorocarpus a/bus Agropyron repens Agrostls spp. Athyrium fllix-femlna Cirsium vulgare Cirsivm arvense Convolvulus sepium Cytisus scoparius Dactylis glomerata Digitalis purpvreum Eplloblum watsonli Equisetum BNense Equisteum IBBvigatum Festuca spp. Geum macrophyllum Geranium spp. Glecoma hederacea Hedera helix Hypericum perforatvm Juncw; effvws Juncus bufon/us Lemna minor Phalarls 11rundinacea lodJcator Status FAC FAaJ NL F,AC FACW+ Fte,W FN; NL FIC,W FAC+ NI FACU- FACU+ NL FACU+ FftC NL FAaJ FACIJ FACW-FACU, NI FAC FACU FACU+ NL NL FAOJ NL 03L FPCW Ff.CW FAC,FACU FAC+ FAU+ FACU..

Vanessa Dolbee LJ)A IC --LC [1 From: Allen Quynn Sent: Wednesday, March 31, 2010 10:15 AM Vanessa Dolbee To: Cc: Amela J. Henninger Subject: Wonderland Estates Proposed Discharge Review Hi Vanessa, Below are my comments on the Draft TIR dated March 16, 2010: 1. The TIR states that discharging site runoff to the northwest corner of the site would alleviate flooding in Wonderland Estates and reduce some of the flooding potential in Lower Madsen Creek. The TIR does not quantify how much flooding would be reduced. It would seem to me that removing 3 cfs from the total tributary flow to Madsen Creek would have negligible improvement in the amount of on site flooding. 2. I'm confused with Table 3.1 on page 13. Under existing conditions for the 25-yr storm, Wonderland Estates contributes 4.52 CFS. Is this because the pumps do not have enough capacity to pump the on site runoff to Madsen Creek? What if the pumps were sized to discharge all the site runoff to Madsen Creek. What would be the amount of increased flooding that would occur at the northest corner of the site? 3. Why is the proposed flow for the 25-yr event 3 cfs for Wonderland Estates in Table 3.1? I would think the proposed flow should be 4.52 cfs + 3.0 cfs or 7.52 cfs which is the capacity of the conveyance system of the proposed discharge route. 4. I don't understand how the existing water surface elevations for Stream A at points A, B, C, D, E and Fare higher than the proposed conditions. The proposal to divert additional flow to Stream A will add 3 cfs for the 25-yr event; therefore, the water surface elevations most increase correspondingly. Table 3.2 shows the 25-yr design flow of 8.81 cfs for existing conditions and 10.33 cfs for proposed conditions. How can this be when flow is being diverted from Madsen Creek? 5. Contrary to Appendix E of the report, Stream A actually flows through a wetland as delineated by the Parks Department. Diverting additional water to Stream A may have adverse impact to the wetland hydrology. 6. The project does not trigger flow control because the proposed improvements will not result in an increase in impervious surface; however, because Stream A is located in an area with erodible soils, any increase in flow could result in erosion and subsequent degradation of water quality. To eliminate this condition, the proposal to divert flows would require that stream A be placed in a pipe all the way to the Cedar River. Constructing a pipe through a wetland is not allowed per City code. Code would require that the pipe be placed in an alignment that avoids the wetland. Placing Stream A in a pipe would change the hydrology of the wetland by reducing the volume of tributary runoff and would require an analysis determine any impacts and appropriate mitigation. Finally, constructing the pipe near a sensitive area would involve federal, state and local permits. 7. The Surface Utility is working with FEMA funds to rehabilitate the Elliot Spawning Channel that was damaged in 2006 and 2009. The channel is located just downstream of Point F. Any increase in flows to Stream A may affect the City's access to the site during construction as well as any proposed water sources to the channel. Please call me if you have any questions.

During our review, staff has determined that additional information is necessary in order to proceed further. The following information will need to be submitted so that we may continue the review of the above subject application: • Applicant must demonstrate the downstream system has capacity using a backwater analysis assuming a tailwater elevation for the 25-and 100-yr design storm(s} at the outfall to the Cedar River and specifically indentify impacts that may adversely affect the City's Park property. At this time, your project has been placed "on hold" pending receipt of the requested information.· Please contact me at (425} 430-7314 if you have any questions. Sincerely, Vanessa Dolbee (Acting} Senior Planner cc: King County Housing Authority-Hugh Watkinson/ Owner(s) Renton City Hall • 1055 South Grady Way • Renton, Washington 98057 • rentonwa.gov I Vanessa Dolbee From: Vanessa Dolbee Sent: To: Wednesday, March 03, 2010 12:52 PM 'Karen Walter' Cc: Helling, Don Subject: RE: Wonderland Estates Utility Replacement, LUA 10-008, ECF, CAR, Notice of Application and Proposed Determination of Non-Significance-Mitigated Ms. Walter, Thank you for your comments and questions related to the subject project. Buy now you should have received an e-mail from Don Helling that provides responses to your questions and some additional information. Your comments have been placed in the project file. Additionally, if you would like a copy of the draft drainage report, there is a copy available at City Hall or the applicant may be able to provide you with an additional copy. Unfortunately we do not have additional copies to send your way. To provide additional clarity to your question 5. the Renton Municipal Code allows for a Critical Areas Exemption for normal maintenance of existing roadways and utilities in wetland buffers. The applicant has applied for this Critical Areas Exemption. Although staff has recommended that to the Environmental Review Committee add a mitigation measure as a part of the SEPA that would require re-vegetation of any disturbed buffer area that results from construction of the subject project. Again, thank you for your comments and consideration on the subject project. Vanessa Dolbee (Acting) Senior Planner City of Renton Department of Community & Economic Development 1055 South Grady Way Renton, WA 98057 (425)430-7314 -----Original Message----- From: Karen Walter [mailto:Karen.Walter@muckleshoot.nsn.us] Sent: Tuesday, March 02, 2010 01:25 PM To: Vanessa Dolbee Cc: Larry.Fisher@dfw.wa.gov Subject: Wonderland Estates Utility Replacement, LUA10-008, ECF, CAR, Notice of Application and Proposed Determination of Non-Significance-Mitigated Vanessa, The Muckleshoot Indian Tribe Fisheries Division has reviewed the Notice of Application materials, including the proposed mitigation measures and threshold determination, environmental checklist, November 11 2009 letter from The Watershed Company, the environmental checklist and the site plans. We have some questions and initial comments as noted below: 1 • 1. We need additional information about waters on or adjacent to the site. The environmental checklist, Section 3.a.1 is incomplete as it only discusses Madsen Creek and the KC constructed highflow bypass and the Cedar River. It does not discuss the wetland and duck pond found on and adjacent to the site (described in The Watershed Company's letter), and the checklist does not discuss the existing Class 3 intermittent stream/swale on the NW corner of the property until item 3.c.1. Please provide more information about the Class 3 intermittent stream such as how it was determined to be a Class 3 stream and detailed information about the proposal to discharge stormwater to this stream in lieu of how stormwater is managed currently. Depending on the nature of this stream/swale, it is likely given its low elevation and potential gradient that this stream is actually used by salmonids when there is flowing water. If this stream could be used by salmonids for any stage of their life history, then routing stormwater to this stream needs to be evaluated for potential impacts to these fish. More information is needed to make this determination. 2. Additional information is needed about the exact work that will occur within all of the waterbodies listed above. Again, the responses to question 3.a.2 appear to be incomplete. 3. Additional information is needed regarding stormwater management. For example, how is stormwater managed and treated today from the site? Is any stormwater from the site routed into the highflow by-pass? If not, why not? Why isn't stormwater proposed to be routed to the highflow by-pass built for Madsen Creek? Will stormwater be treated and detained prior to release from the site? If not, why not? The checklist notes that the location of the discharge point will be adjusted to no longer discharge site runoff to the mapped flood hazard onsite; this is a good idea but where will the stormwater be discharged? What analysis has been done to determine how changes in stormwater management and discharge will affect the receiving waters and Madsen Creek? To answer these questions, it might be useful if the City sent the drainage report developed for this project and listed in the environmental checklist in item 8. 4. Will there be additional fill within the 100 year floodplain? The checklist notes that a sanitary sewer pipe connection will occur but does not indicate if this will result in additional fill or if there is a reduction in fill as a result of this project. More information is needed. 5. It appears that the project will maintain encroachments into the regulated wetland buffer and potentially the stream buffer for Madsen Creek. If so, the project should be required to mitigate for these impacts to address both site specific and cumulative losses to restore the wetland (and potentially stream) buffers. Ideally mitigation would occur onsite; however, it may be necessary to mitigate elsewhere offsite in the Madsen Creek basin. 6. The site plans do not show where the proposed stormwater pump will be constructed that is described in item 3.c.3 on page 7 of the checklist. We appreciate the opportunity to initially review this proposal and look forward to responses to these questions and additional information that may help us better understand this project and its potential impacts t~ salmonids.

The environmental checklist, Section 3.a. 1 is incomplete as it only discusses Madsen Creek and the KC constructed highflow bypass and the Cedar River. It does not discuss the wetland and duck pond found on and adjacent to the site (described in The Watershed Company's letter), and 1 the checklist does not discuss the existing Class 3 intermittent stream/swale on the NW corner of the property until item 3.c.1. Please provide more information about the Class 3 intermittent stream such as how it was determined to be a Class 3 stream and detailed information about the proposal to discharge stormwater to this stream in lieu of how stormwater is managed currently. Depending on the nature of this stream/swale, it is likely given its low elevation and potential gradient that this stream is actually used by salmon ids when there is flowing water. If this stream could be used by salmon ids for any stage of their life history, then routing stormwater to this stream needs to be evaluated for potential impacts to these fish. More information is needed to make this determination. We apologize for not referring to the on-site duck pond and category 3 wetland. and that the description provided in the SEPA Checklist was not clear regarding the discharge conveyance away from the site. The Class 3 intermittent stream is located a substantial distance off-site. A downstream drainage analysis was performed from the Wonderland site to the location one-quarter mile downstream where the roadside ditch (for Renton-Maple Va/fey Road) enters the Class 3 intermittent stream. From this location the stream was field-reviewed to the extent practical (limited access due to fencing and heavy growth of blackberries) to its confluence with the Cedar River. We did not classify the intermittent stream, but the adjacent Pioneer Place Plat's file indicates that King County ODES classified this intermittent stream as Class 3 in their review of that developmenrs application. We propose the fa/lowing addition to Section 3.a.1 of the SEPA checklist. "There is a category 3 slope-type wetland on the southern edge of the site extending off site to the south up the steep slope. In addition there is a constructed ornamental Duck Pond of approximately 1000 SF surface area in the SE portion of the site adjacent to the wetland. The proposed storm drainage discharge from the Wonderland site is a roadside swale that flows toward a Class 3 intermittent stream (identified as such by King County OOES's Pioneer Place subdivision review) is located approximately 1,250 feet west of NW corner of the Wonderland site. This stream then flows an additional 1,000 feet to its confluence with the Cedar River." In addition, we propose the fa/lowing addition to Section 3. c. 1 of the SEPA checklist "The surface water runoff from Wonderland Estates is currently discharged directly into Madsen Creek via a pumped system. Flooding problems of Madsen Creek are documented in the drainage TIR for this project. To mitigate the flooding issues. it is proposed that the drainage discharge for this project be relocated to a drainage course with more available capacity" 2. Additional information is needed about the exact work that will occur within all of the waterbodies listed above. Again, the responses to question 3.a.2 appear to be incomplete. There is no work including the drainage discharge point, proposed in any water body The proposed discharge location at the northwest corner of the Wonderland site is a roadway ditch for the Renton-Maple Va/fey Road. 3. Additional information is needed regarding stormwater management. For example, how is stormwater managed and treated today from the site? Storm water is coffected and discharged directly to Madsen Creek without water quality treatment or designed detention. Is any stormwater from the site routed into the highflow by-pass? No If not, why not? The ground surface of Wonderland Estates naturaffy slopes from south to north. The most natural and probable historic discharge location is at the north end of the Park site. Why isn't stormwater proposed to be routed to the highflow by- pass built for Madsen Creek? It was elected to keep the discharge location at the natural north end of the Park site. Will stormwater be treated and detained prior to release from the site? If not, why not? Stormwater wi/1 be detained to prevent flooding in the downstream conveyance system prior to discharge from the site. Drainage is proposed to be discharged into the roadside ditch which due to its flat gradient and vegetation will provide some degree of water quality treatment. The checklist notes that the location of the discharge point will be adjusted to no longer discharge site runoff to the mapped flood hazard onsite; this is a good idea but where will the stormwater be discharged? What analysis has been done to determine how changes in stormwater management and discharge will affect the receiving waters and Madsen 2 Creek? The Wonderland Estates discharge to Madsen Creek 1s comprised solely of storm water discharge and does net contribute to the Creek's base flmv To answer these questions, it might be useful if the City sent the drainage report developed for this project and listed in the environmental checklist in item 8. 4. Will there be additional fill within the 100 year floodplain? The checklist notes that a sanitary sewer pipe connection will occur but does not indicate if this will result in additional fill or if there is a reduction in fill as a result of this project. More information is needed. No additional fill is proposed. Only a sewer pipeline connection will occur within the 100 year floodplain. No change in ground surface contours will occur within the designated 100-year floodplain. 5. It appears that the project will maintain encroachments into the regulated wetland buffer and potentially the stream buffer for Madsen Creek. If so, the project should be required to mitigate for these impacts to address both site specific and cumulative losses to restore the wetland (and potentially stream) buffers. Ideally mitigation would occur onsite; however, it may be necessary to mitigate elsewhere offsite in the Madsen Creek basin. There is not change in use of the Wonderland site. This project replaces infrastructure that has exceeded its life expectancy Only underground utility replacement and reconstruction of existing roadways will occur. An actual decrease in impervious area will occur due to the reduction in width of two of the on-site roadways. The project is being designed per the City of Renton requirements. 6. The site plans do not show where the proposed stormwater pump will be constructed that is described in item 3.c.3 on page 7 of the checklist. The storm drainage discharge detention and discharge facility is located between the Park's entry drive and the northwest corner of the Park. The storm drainage pump station is located at this location as well. We appreciate the opportunity to initially review this proposal and look forward to responses to these questions and additional information that may help us better understand this project and its potential impacts to salmonids.

Chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact.

Park property to the south of the project site is a hill that slopes downward to the project site. The steep slope is outside of the project limits. b. What is the steepest slope on the site (approximate percent slope?) No slopes greater than 10% have been identified within the limits of construction A 68% slope has been identified in the southwest part of the Park property outside of the project site; this steep slope area is outside of construction limits for the project site. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The USDA Natural Resources Conservation Service has mapped Soils on the project site as predominantly "Urban land". The steep forested slopes in the southern portion of the Estates are mapped as Alderwood and Kitsap Soils, while the area on the flatter slopes surrounding the Estates is mapped as Newberg silt loam. The flatter area of the Wonderland Estates Area mapped us Urban Land is assumed to be Newberg silt loam based on the soil map. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Geologic maps indicate the presence af Landslide Deposits about 300 feet east of the site; these landslide deposit are outside of the project area. We did not observe surface indications of unstable soils in the project site. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Grading work is proposed to facilitate the installation of underground utilities, reconstruct on-site roadways, and enhance site storm drain and system.

There will be a slight decrease in net impervious surface following completion of this project. -4- J:\15093201 Wonderland Estates\04_PROJ D0CS\09_Applications1CA-SP-ER Application Materials\05-Env Checklist- SEPA\10.04.09.COR.SEPA.CHKLIST.doc 06109 h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: 2. AIR A Temporary Erosion and Sedimentation Control (TESC) Plan approved by the City of Renton will be implemented during construction of the proposed project. The Plan will incorporate BMP's per the King County Storm Water Management Manual. For further details please refer to the TESC plan that is included as o part of the construction permit submittal. a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. During construction there will be exhaust emissions from large construction equipment (trucks, excavators, bulldozers, etc.) Dust may occur from utility trench excavation and backfill, and in the period prior to roadway paving. Following completion of the project, the project should not change existing emissions. b. Are there any off-site sources of emission or odor that may affect your proposal? If so, generally describe. None that we are aware of. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Construction dust will be controlled by requiring the contractor to cover or water down exposed dirt. 3. WATER a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The Cedar River is across the SE Renton Maple Valley Road, approximately 800 feet north of the site. Madsen Creek, a City of Renton Mapped Class II Salmonid Stream, flows out of an off-site ravine located south of the subject property. The stream flows into a City sedimentation pond located immediately south of the Pork's southern property line. This pond has two outlets; the original stream channel and a high flow bypass channel built by King County. The original stream channel flows easterly, and then gradually bends north, eventually bending west and parallel to SR 169. The channel flows across the front of the subject property for approximately 90 -5- J:\ 15093201 Wonderland Estates\04_PROJ DOCS\09 _Applications\CA-SP-ER Application Materials\05-Env Checklist- SEPA\10.04.09.COR.SEPA.CHKUST .doc 06109 feet before flowing north beneath SR 169 to its confluence with the Cedar River. The high-flow bypass channel flows parallel to the eastern property line, separated from the Park property by a berm with a gravel road on top. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The project will not require work within 200 feet of the Cedar River. Small components of the northern and southern ends of the site are within 200 feet of Madsen Creek. Work within 200 feet will involve tasks associated with underground utility replacement and surface restoration. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No fill or dredge material will be placed in or removed from surface water or wetlands as part of this proposal. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. The project will not require surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year flood plain? If so, note location on the site plan. A sanitary sewer pipe connection to the existing public sewer manhole will occur within the 100 year floodplain (FIRM, Map Number 53033C0984K, No Effective Date). The two existing storm droin pump station discharge pipes will be replaced with the same diameter pipelines at existing location. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. The infrastructure improvements at the site do not include plans to discharge waste materials to surface waters. b. Ground Water: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. It is anticipated that trench dewatering will occur during construction in order to facilitate safe trench excavation and appropriate trench backfill and compaction. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals ... ; agricultural; etc.). Describe the general -6 - J:\15093201 Wonderland Estates\04_PROJ D0CS\09_Applications\CA-SP-ER Application Materials\05-Env Checklist- SEPA\10.04.09.COR.SEPA.CHKLIST.doc 06/09 4. size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None anticipated. c. Water Runoff (including storm water): 1} Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters, If so, describe. On-site storm water generally flows south to north/northwest towards the northwest corner of the site. The altered topography, due to construction of SR - 169 to the north and Pioneer Place to the west, has resulted in the need to pump storm water runoff from the site. Water courses in the area include Madsen Creek, a bypass channel of Madsen Creek, and a roadside ditch/swale system that conveys road runoff to the west along the south side of SR 169. The existing on-site drainage system collects stormwater runoff by gravity flow in a pipe network and pumps low flows to Madsen Creek at two locations. The project proposes ta maintain the current drainage configuration to discharge to the swale leading to Stream A. Regrading in the northwest corner of the site will be used to create storm water storage volume and reduce the potential of on-site flooding. 2) Could waste material enter ground or surface waters? If so, generally describe. Trench dewatering runoff during construction will be filtered prior to release from the site. Waste materials are not anticipated to enter ground or surface waters. 3) Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: The on-site flow characteristics will not be altered, except for replacing sheet flow with pipe flow over a short distance. Regrading in the northwest corner of the site will increase the storage volume and control the impact of stormwater runoff on-site and off-site. · PLANTS a.

The "On Hold" notice was given in regard to the Wonderland Estates proposed reroute of pumped low storm drainage flows to a swale westward along the Maple Valley Highway (SR 169) along the Pioneer Place development's frontage, then into "Stream A", a tributary of the Cedar River that originates in wetland located south of the Pioneer Place development. "Stream A" on the north side of SR 169 flows between Ron Regis Park and the Maplewood Gold Course, eventually outfalling into the Cedar River. We do not concur that the proposed shift of the low flow storm drainage discharge would affect the "Stream A" area. We do acknowledge that pursuing this proposed drainage reroute further will likely result in delays that could jeopardize 2010 construction for this project. Therefore we are proposing that the existing storm drainage pump system discharge be kept operating as is. The two existing Wonderland Estates pump station structures will be replaced. The existing pumps will remain operating in their current configurations and locations. The force main discharge piping will be replaced with new piping of the same diameters and at the same locations. The remainder of this letter describes some of the advantages of the storm water management system that was proposed for Wonderland Estates and provides a written response to the City's April 2, 2010 letter. In our opinion the advantages of the storm water management system that was proposed for Wonderland Estates are: • Only pumped low storm water flows will be diverted from their current discharge locations to Madsen Creek via the swale system along SR 169. The increase in flow to be directed to the swale system along SR 169 and "Stream A" would be 0.6 cfs or less ( 42% of the site 2-year runoff rate). Larger storm events that result in Madsen Creek overtopping its banks (at Wonderland Estates) would not be affected by the proposed low flow discharge rerouting. The storm water runoff from larger storm events currently J:115093201 Wonderland Estatesl02_CORRESP0NDENCE\01_Letters & Memo\2010.0409 renton hold response.doc 1 drains un-attenuated from Wonderland Estates and flows toward "Stream A". This proposal would not adversely change this condition. • Discharging low flow pumped storm drainage westward from Wonderland Estates into a swale adjacent to SR 169 would create an opportunity lo provide water quality treatment to the flow. • A detention pond provided on the Wonderland Estates site would allow control of the 25- year runoff rate to a rate determined to not cause surcharge or flooding in the downstream system. The modeled flow limit would be 3.0 cfs. The detention pond would attenuate site storm water discharge to "Stream A" so that ii would actually be at lower peak rates than the existing 4.52 cfs (for the 25-year event). The following are the City of Renton's comments (indented) with Wonderland Estates' project responses following (in bold). 1. As proposed, additional stormwater would be diverted from its currant drainage location of Madsen Creek into a new stream tributary identified in the provided TIR as "Stream A". Stream 'A' flows through the City's Ron Regis Park and eventually outfalls into the Cedar River. A Biological Impact Assessment Memo completed by the Watershed Company was provided in Appendix E of the TIR report. Within this Assessment, The Watershed Company indicates that no wetlands were observed along Stream A. The City believes this report is in error, because a wetland was identified in this area during the Cedar River Regional Park Master Plan process. The diversion of additional stormwater, to this wetland, may have adverse impact to the wetland hydrology. The additional stormwater runoff could result in an increase in the wetland size and/or value affectively increasing its buffer size and/or area. If the wetland changes in size and/or value it would have adverse impacts on the Cedar River Regional Park Master Plan and anticipated improvements for Ron Regis Park. Furthermore, the City has received grant funding for Ron Regis Park from the Recreation and Conservation Office (RCO) and the Federal Land and Water Conservation; these grant funds require that particular improvements are made to the Park. Changes to the wetland or Stream 'A' may impact the City's ability to comply with the grant funding requirements. The January 12, 1993 wetland study may not reflect current conditions with regard to wetland configuration in this area. In addition, please find enclosed an April 8, 2010 letter from our subconsultant, The Watershed Company, which further discusses this subject. J:\15093201 Wonderland Estates\02_CORRESPONOENCEI01_Letters & Memo\2010.0409 renton hold response.doc 2 2. Additionally the City is working with potential FEMA funds to rehabilitate the Elliot Spawning channel that was damaged in the 2006 and 2009 Cedar River flooding events. The Elliot Spawning channel is located just downstream of point F of Stream 'A', as identified in the TIA. Any increase in Stream flows may affect the City's access to the site during construction as well as potentially impact the spawning channel itself. The proposed routing of low flow storm drainage discharge toward "Stream A" would not increase flow to this area as in low flow situations the storm drainage runoff from the south side of SR 169 is held in a detention facility located between SR 169 and the Cedar River Trail. No changes are proposed for high storm flow discharges from Wonderland Estates toward "Stream A" as the current condition is that Madsen Creek tops its banks and flows toward and through the Pioneer Place development and on toward "Stream A". The proposed drainage discharge changes at Wonderland Estates would route a significant portion of high storm flow discharge toward a swale along SR 169, instead of its current overflow path through Pioneer Place. This would not increase high flow peak discharge rates from Wonderland Estates. In addition, the City's April 2, 2010 letter presented the following City Stormwater Division questions and concerns. 1. The TIR states that discharging site runoff to the northwest corner of the site would alleviate flooding in Wonderland Estates and reduce some of the flooding potential in Lower Madsen Creek. The TIR does not quantify how much flooding would be reduced. It would seem that removing 3 cfs from the total tributary flow to Madsen Creek would have negligible improvement in the amount of on site flooding. The storm drainage discharge and routing proposal provided for the removal of 0.6 cfs (not 3 cfs) of on-site runoff from discharge to Madsen Creek. There was no intention to "remove 3 cfs from the total tributary flow to Madsen Creek". We acknowledge that the decrease in flooding potential in Madsen Creek would be slight from removing 0.6 cfs from the discharge. The reduced flooding potential would be the result of routing the Wonderland Estates on-site storm drainage through a conveyance system that includes the proposed on-site detention pond and then discharging from the site into a defined swale along SR 169. 2. The Storm water Division is confused with Table 3.1 on page 13. Under existing conditions for the 25-yr storm, Wonderland Estates contributes 4.52 CFS. Is this because the pumps do not have enough capacity to pump the on site runoff to Madsen Creek? What if the pumps were sized to discharge all the site runoff to Madsen Creek. J:\15093201 Wonderland Estates\02_CORRESP0NDENCEI01_LeUers & Memo\2010.0409 renton hold response.doc 3 What would be the amount of increased flooding that would occur at the northwest corner of the site? The existing condition 4.52 cfs 25-year discharge from Wonderland Estates discharges from the northwestern portion of the Wonderland site. During this event Madsen Creek is flooding onto the site (at an unknown rate) and the pumped rate of 0.6 cfs re-circulates back onto the site resulting in no net storm discharge flow into Madsen Creek (as occurred in January 2009 during a storm estimated to be between the 10 and 25-year event). If the pumps were sized to pump a higher rate, the discharge to the NW corner would still be 4.52 cfs, because the creek is flooding. 3. Why is the proposed flow for the 25-yr event 3 cfs for Wonderland Estates in Table 3.1? One would think the proposed flow should be 4.52 cfs + 3.0 cfs or 7.52 cfs, which is the capacity of the conveyance system of the proposed discharge route. The proposed 25-year discharge from Wonderland Estates is 3 cfs. This reduction from the current calculated 4.52 cfs is a result of a proposed control structure (detention pond and weir) at the northwest corner of the Wonderland site that would limit the discharge to that rate. This was proposed in order to prevent flooding at a downstream chokepoint along SR 169 that was identified by the backwater analysis. 4. The Storm water Division doesn't understand how the existing water surface elevations for Stream A at points A, B, C, D, E and F are higher than the proposed conditions. The proposal to divert additional flow to Stream 'A' will add 3 cfs for the 25-yr event; therefore, the water surface elevations must increase correspondingly. Table 3.2 shows the 25-yr design flow of 10.33 cfs for existing conditions and 8.81 cfs for proposed conditions. How can this be when additional flow is being diverted to Stream 'A'? The proposal to divert discharge storm drainage from Wonderland Estates toward "Stream A" would add 0.6 cfs during low flow events only. During high flow events Madsen Creek leaves its banks and all flows from Wonderland Estates flows toward "Stream A". The reduction in water surface elevation during the 25- year event is the result of the proposed pond and weir at the northwest corner of the Wonderland Estates site that would control the discharge to 3.0 cfs (instead of letting the entire 4.52 cfs pass uncontrolled). The proposal would have limited the 25-year discharge to less than the current condition. 5. The project does not trigger flow control because the proposed improvements will not result in an increase in impervious surface; however, because Stream 'A' is located in an J:\15093201 Wonderland Estates\02_CORRESP0NDENCE\01_Letters & Memo\2010.0409 renton hold response.doc 4 • · . area with erodible soils, any increase in flow could result in erosion and subsequent degradation of water quality. To eliminate this condition, the proposal to divert flows would require that Stream 'A' be placed in a pipe all the way to the Cedar River. Constructing a pipe through a wetland is not allowed per City code. Code would require that the pipe be placed in an alignment that avoids the wetland. Placing Stream 'A' in a pipe would change the hydrology of the wetland by reducing the volume of tributary runoff and would require an analysis determine any impacts and appropriate mitigation. Finally, constructing the pipe near a sensitive area would involve federal, state and local permits. The proposal will not increase flows to "Stream A" during erosive events. The additions to flow are at the low range of flows up to 0.6 cfs or 42% of the 2-year runoff rate. This is not the range typically associated with erosive velocities. The higher (potentially erosive) flow rates would be reduced or unchanged from the existing condition. The City of Renton is appropriately concerned with the potential impacts of the project on the wetlands, on the park improvements, and on park and FEMA funding for these important projects. The basis of the concern appears to be the purported "increase in Stream flows" that would result from the project. As described above, increases in Stream A flows are proposed to be limited to flows below 0.6 cfs or 42% of the 2-year runoff from Wonderland Estates. Higher flows up to the 25-year event were to be controlled to below current conditions. The City's April 2, 2010 letter suggests that Wonderland Estates look at alternative discharge locations. Although we do not believe that the proposed shift of the low flow storm drainage discharge from being pumped directly into Madsen Creek to being discharged in a swale westward from the Wonderland site would affect the "Stream A" area, we acknowledge that pursuing this proposed drainage reroute further will likely result in delays that could jeopardize 2010 construction for this project. The revised Project Narrative. SEPA Checklist. Drainage and Site Plans. and Storm Drainage TIR will be submitted for review upon scheduling an appointment with you to do so. We appreciate the City's attention in providing review of these documents and assistance in removing the "on-hold" status of the project.

Section 1 of that letter specifies concerns with the March 4, 2010 letter 'Wonderland Estates Stormwater Diversion -Biological Impacts Assessment Memo" (Impact Assessment) written by The Watershed Company, which states, "no obvious wetland areas were observed along any portion of the lower segment of Stream A." This letter is intended to clarify that statement and its suggested conflict with a previous delineation (Delineation Report) conducted by The Watershed Company in 1993, which indicated that wetland conditions were present along Stream A at the time of the delineation. The previous delineation was conducted 17 years ago, prior to construction of Ron Regis Park, and should not be relied upon as accurately portraying the current wetland boundary. The science of wetland delineation has evolved significantly since 1993, including revisions to delineation manuals by the U.S. Army Corps of Engineers (Corps) and the Washington State Department of Ecology (Ecology), as has the landscape of the surrounding area. The Delineation Report indicated that the entire northern half of the park was wetland at the time of the delineation study. Much of that wetland area is undeniably still present and was referenced in the Impact Analysis. However, natural and man-made processes, including changes to the Cedar River floodplain, the development of Ron Regis Park and the continued urbanization of the surrounding landscape, have likely altered the extent of the wetland area, which currently appears to be smaller than in 1993. The Delineation Report explained, 'The hydrology of the area is likely to be changing due to the activity of beavers. A dam has been constructed on Madsen Creek, creating a small pond, and recent activity is evident. Because of the presence of beavers, the location of the wetland boundary may change in the future." 750 Sixth Street South Kirkland, WA 98033 p 425.822.5242 / 425.827.8136 watershedco.com • Response to Request for Additional Information Don Helling, Huitt-Zollars April 8, 2010 Page2 The ever-changing nature of wetland boundaries, particularly in highly urbanized environments where hydrology is significantly influenced by rapidly-fluctuating flood events is a primary reason that wetland delineations are typically not valid for more than five years. The Renton Municipal Code agrees with this premise, stating that wetland delineations within the city limits are valid for five years, unless the Administrator determines that conditions have changed. The Corps and Ecology have similar "five-year" rules. The purpose of my inspection and the subsequent memo was to address potential impacts from the proposed stormwater diversion, as they would pertain to amphibian and fish habitat. The Impact Assessment was not intended to serve as a formal wetland delineation report. However Stream A is presently surrounded by an extensive Himalayan blackberry monoculture throughout most of its on-site length. Even though Himalayan blackberry can grow in wetlands, it is considered a facultative upland plant and rarely forms extensive monocultures over large portions of wetlands. Additionally, the intermittent nature of Stream A appears unlikely to provide significant enough hydrology to support a riverine wetland, meaning any wetland areas, if present, would be primarily supported by groundwater, not overbank flooding from Stream A. Therefore, while some small, isolated areas meeting wetland criteria may be located along Stream A, it is highly unlikely that any areas capable of providing significant amphibian habitat would be present in this area. The overall likelihood of the stormwater diversion contributing to an increase in the size of any potential wetland areas along Stream A or the large riparian wetland associated with Madsen Creek and the Cedar River, as suggested in Section 1, is relatively low. Increased levels of hydrology would only occur in Stream A during heavy storm events, which occur primarily during the winter dormant season. To satisfy wetland criteria, wetland hydrology is required to be present during a significant portion of the growing season and must contribute to the formation of hydric soils and a hydrophytic plant community. Groundwater levels during the growing season would not increase as a result of the proposed stormwater diversion. Therefore, it is highly unlikely that hydric soils and hydrophytic vegetation, if present, would expand beyond their current locations. I hope this further explanation adequately addresses your concerns. Please call if you have any questions or if we can provide you with any additional information.

The proposal violates Core Requirement No. 1 of the City's Surface Water Design Manual since the project runoff will discharge into a drainage system that is not the natural discharge locations. In order for the Su,face Water Utility to consider this request, the applicant must do the following: a. Since the open channel segment downstream of SR-169 crosses through City Parks Department property before discharging into the Cedar River, the applicant must obtain permission .from the City of Renton Parks Department. ..You need to meet with Leslie Betlach to discuss the option of discharging additional water into this drainage system. The applicant will need to demonstrate the advantages and how the Parks Dept. wm benefit .from discharging project runoff into the proposed drainage course versus the current drainage course (Madsen Creek). We met with Leslie Betlach as requested; the revised TIR attempts to address her concerns. The advantages of the proposed discharge to the Parks Department are: (I) the biological impact which is addressed in Appendix E of the TIR and (2) the hydraulic impact discussed in the TIR in Section 3.2 Backwater Analysis. b. Although site runoff currently drains to Madsen Creek at the northeast comer of the site, the TIR stales that the natural drainage is to the swale system along SR-169 at the northeast comer. The applicant will need to demonstrate that the historic drainage path for the project runoff was to the northwest. Historic topographic maps (such a USGS quad maps}maybe helpfal here. We make no pretense of knowing the location of the "natural" discharge point and have revised the TIR accordingly. Historic photos and other available information are inconclusive as to the natural discharge location. The current, low-flow discharge (up to 0.6 cfs only), is to Madsen Creek. Higher flows, including the 25- yr and I 00-yr peaks, already discharge to the proposed location. The proposal will not change peak flows to the swale, except to control (improve) the 25-yr recurrence interval performance. This item is discussed in most depth in Section 3.2 Backwater Analysis. c. The applicant will need to make the necessary improvements to the downstream drainage system such that it has the capacity to convey the total tributary runoff as required under Core Requirement No. 4 of the City's Su,face Water Design Manual. This may include but is not limited to removal of debris in swales and replacement of improperly constructed storm pipe. We acknowledge the responsibility of making the needed improvements to the downstream swale system.

Figure 1 shows the project location on a Vicinity Map of the project area, and Figure 2 presents a Site and Exploration Plan showing the general layout of the roadways and proposed utilities and the locations of our explorations. This report is organized as follows: • Introduction; • Purpose, Scope, and The Use of This Report; • Site and Project Descriptions; • Subsurface Conditions; • Geotechnical Engineering Design Recommendations; and • Recommended Additional Geotechnical Services. Figures are presented at the end of the text. The field exploration procedures and logs are presented in Appendix A. The laboratory procedures and test results are presented in Appendix B. 2.0 PURPOSE, SCOPE, AND THE USE OF THIS REPORT 2.1 Purpose Hart Crowser The purpose of our work has been to: • Assess subsurface conditions at the Wonderland Estates development; • Address potential on-site infiltration of stormwater; • Address potential geologic hazards; and • Provide geotechnical engineering recommendations related to the design and construction of the proposed infrastructure upgrades. These include roadways, utilities within roadways, and mainline utilities located outside the roadways. Page 1 17586-01 February 17, 2010 2.2 Scope of Work Our scope of work to address the geotechnical design aspects of the project included the following items. We were to: • Conduct subsurface explorations along the existing roadways, which generally correspond to the proposed alignments for the new buried utilities; • Perform laboratory testing on selected soil samples; • Develop geotechnical engineering design recommendations; and • Present the results of our study in this report. 2.3 The Use of This Report We completed this work in general accordance with our contract dated October 8, 2009, with Huitt-Zollars, Inc. This report is for the exclusive use of King County Housing Authority, Huitt-Zollars, Inc. and their consultants for specific application to the subject project and site. We completed this design study in accordance with generally accepted geotechnical practices for the nature and conditions of the work completed in the same or similar localities, at the time the work was performed. We make no other warranty, express or implied. 3.0 SITE AND PROJECT DESCRIPTIONS 3.1 The Site Wonderland Estates is located in western King County on the south side of SE Renton Maple Valley Road (SR 169) at 149th Avenue SE. The site is approximately 900 feet (north-south) by 500 feet (east-west), covering an area of approximately 10 acres. It is a residential community generally consisting of asphalt-paved streets, mobile or modular homes situated on concrete pads, and associated greenbelts at the edges of the parcel. In general, the developed portion of the site is fairly flat, sloping slightly downward to the north. It ranges in surface elevation from about 120 feet at the south end to 100 feet at the north end near SR 169. There is an undeveloped hill in the extreme southwest corner of the site that slopes steeply upward toward the southwest. 3.2 Our Understanding of the Proposed Infrastructure Improvements In general, we anticipate that infrastructure improvements will include: Hart Crowser Page 2 17586-01 February 17. 2010 • Resurfaced roadways, generally along the same right of ways as the existing streets. Final site grades will generally be the same as the existing grades. No significant cuts or fills are planned. • New subgrade utilities including storm sewer, sanitary sewer, water lines, and electrical lines. Most utilities will be about 3 to 5 feet below grade, although some limited portions of the storm and sanitary sewer lines will be at a maximum depth of 8 feet below grade. • Replacement of an existing curtain drain at the south end of the site. The new curtain drain will likely be on the order of 3 to 4 feet deep and extend in an east-west direction near the south edge of the existing paved area. The new curtain drain will simply replace the function of the existing drain. Initially, potential on-site infiltration of stormwater was being considered. That concept has been dropped however, because soils and groundwater conditions are not favorable for infiltration. 4.0 SUBSURFACE CONDITIONS Our understanding of the subsurface conditions is based on information obtained from nine hollow-stem auger borings (HC-1 through HC-9). The borings, completed on January 21, 2010, were each drilled to a depth of 14 feet. The boring locations are shown on Figure 2. Detailed boring logs of the conditions observed at the exploration locations are included in Appendix A, and should be referred to for specific information. Results of the laboratory tests conducted for this study are presented in Appendix B. We based our interpretation of subsurface conditions on materials encountered in our explorations at discrete locations. The nature and extent of variations between explorations or at other locations could vary and may not become evident until construction begins. If variations then appear evident, it may be necessary for Hart Crowser to re-evaluate the recommendations in this report. 4. 1 Soil Conditions Hart Crowser Our borings generally encountered very loose to medium dense alluvial soils from the ground surface downward. These materials consisted primarily of silt, sand, gravel, and combinations thereof. A consistent pattern or trend with depth was not apparent, although the uppermost material within about 2 feet beneath Page 3 17586-01 February 17, 2010 the pavement section appeared to be slightly denser than the material directly below it. Most of the alluvial soil encountered consisted of sandy silt to silty sand, however, at some locations, our borings encountered zones of gravel and at other locations, borings encountered very soft, very sandy silt. Of particular note were the following: • Boring HC-5. Very soft zone at 8-foot depth. • Boring HC-8. Scattered wood debris at 7-foot depth. • Boring HC-9. Very loose to very soft zone with scattered wood debris at about 5-to 10-foot depth. The nine borings were each advanced to a depth of 14 feet. Three of the nine borings were terminated in very dense soils. The remaining six borings were still within loose to medium dense soils at their termination depth. The loose, soft or medium dense soils are not suitable for direct support of pavement sections, on-grade utilities, or structural fill in their present condition. To provide suitable support for these overlying elements, these soils would need to be compacted in place to a dense condition or removed and replaced with structural fill. Alternatively, if the soils are wet (as we expect), compaction would be difficult and other ground improvement methods could be used, as discussed herein. 4.2 Groundwater At the time of drilling, our borings consistently encountered groundwater at a depth of 2-1 /2 to 5 feet below the ground surface. Note that measured groundwater levels are representative for the time indicated. Fluctuations in groundwater levels may occur due to variations in rainfall, temperature 1 seasons, and other factors. 5.0 SEISMIC CONSIDERATIONS Hart Crowser The site is located in a seismically active area. In this section, we describe the seismic setting at the project site and discuss seismically induced geotechnical hazards. Page 4 17586-01 February 17, 2010 5. 1 Seismic Setting The seismicity of western Washington is dominated by the existence of the Cascadia Subduction Zone (CSZ) in which the offshore Juan de Fuca plate is subducting beneath the continental North American plate. Three main types of earthquakes are typicaNy associated with subduction zone environments- crustal, intraplate, and interplate earthquakes. Seismic records in the Puget Sound area clearly indicate the existence of a distinct shallow zone of crustal seismicity (e.g., the Seattle Fault) that may have surficial expressions and can extend to depths of up to 25 to 30 km (15 to 18 miles). A deeper zone is associated with the subducting Juan de Fuca plate and produces intraplate earthquakes at depths of 40 to 70 km (24 to 42 miles) beneath the Puget Sound region (e.g., the 1949, 1965, and 2001 earthquakes) and interplate earthquakes at shallow depths near the Washington coast (e.g., the 1700 earthquake with an approximate magnitude of 9.0). 5.2 Seismically Induced Geotechnical Hazards Hart Crowser Potential seismically induced geotechnical hazards at the site that we considered include liquefaction, surface rupture, lateral spreading, and landslides. Our review of these hazards is based on the soils encountered in our explorations, regional experience, and our knowledge of local seismicity. 5.2.1 Liquefaction Liquefaction refers to the reduction of shear strength in saturated, granular deposits due to pore water pressure buildup. Pore pressure buildup can occur as a result of cyclic shaking during an earthquake. While the soil is in a liquefied state, it has the physical properties of slurry. Vertical or lateral movements that are potentially damaging to structures could result from liquefaction. A significant portion of the site soils are in a loose to medium dense condition, and are below the water level. As such they are susceptible to liquefaction. As stated above, this could result in significant settlement of surface pavement, catch basins, manholes, buried pipelines, and other structures that are supported above the liquefiable soils. The actual amount of settlement that could occur along pipelines and at the ground surface as a result of a seismic event is difficult to quantify given the depth of explorations. Total settlement depends in part on the thickness of the underlying soil that liquefies. Based on our assessment of this thickness, we estimate that total settlement at the ground surface due to soil liquefaction could be on the order of 6 inches or so. Because the liquefaction potential is similar Page 5 17586-01 February 17, 2010 for soils across the site, we anticipate that differential settlement between utility pipe segments or pipes and catch basins, for example, would be about 1 /2 to 3/4 of the total settlement. We recommend that the design consider this potential total and differential settlement. 5.2.2 Surface Rupture We are not aware of any known faults that intersect the site. Therefore, the potential for surface rupture is considered very small. Rather than attempting to design against potential surface rupture, in our opinion, it would be reasonable for the owner to plan for the repair of any damage that surface rupture may cause. 5.2.3 Lateral Spreading and Landslides Based on the topography and anticipated soil conditions at the site, it is our opinion that the potential for lateral spreading is very small and does not warrant special design considerations. Although there is some potential for seismically- induced landslides to occur in the steep slope area at the southwest corner of the site, this area is mapped as glacial till (typically very dense), and in our opinion the risk of significant sliding is relatively low and would not typically warrant special design considerations. 6.0 GEOTECHNICAL ENGINEERING DESIGN RECOMMENDATIONS This section of the report presents our conclusions and recommendations regarding the geotechnical aspects of design and construction for the infrastructure improvements. We have developed our recommendations based on our current understanding of the project and the subsurface conditions encountered by our explorations. If the nature or location of the proposed improvements is different than we have assumed, Hart Crowser should be notified so we can change or confirm our recommendations. 6. 1 General Considerations Hart Crowser Based on the current design plans and our discussions with the design team, the following represent the primary geotechnical considerations for design and construction for the proposed site improvements: • A significant portion of the site soils are in a loose to soft condition and are not suitable, in their present condition, for direct support of pavement sections or on-grade utilities. Page 6 17586-01 February 17, 2010 • • Pavement sections would require the removal or recompaction of these unsuitable soils within a recommended depth below the crushed rock layer. • Where these unsuitable soils are present directly beneath on-grade utilities, they would also need to be removed or recompacted to a dense condition within a recommended depth beneath the utility invert elevation. • Recompaction of the unsuitable soils to a dense condition would be difficult due to the relatively high water table. As a minimum, the soils below about 2 feet in depth would likely be too wet to compact effectively. For planning purposes, it is reasonable to assume that these soils will need to be removed and replaced with imported structural fill. • In some areas, where subgrade soils are particularly soft or loose, a geotextile fabric may also be necessary beneath the imported structural fill layer. • Potential settlement due to soil liquefaction, as discussed herein, should be considered when designing the subgrade utilities and pavement sections. Flexible couplings or other means may be appropriate to accommodate potential differential settlement. • Due primarily to the relatively high groundwater level, on-site stormwater infiltration is not feasible. • We do not expect that the proposed construction will have a significant effect on the stability of the hillside at the south end of the site or any other nearby slopes. 6.2 Site Preparation Hart Crowser Site preparation will consist primarily of removal of the existing pavement materials and some small areas of sod and topsoil. We recommend the following; • Remove the uppermost layer of pavement and unsuitable soils as recommended herein, to provide a suitable subgrade for the proposed pavement sections. • Do not use the stripped pavement or organic material as structural fill. • Remove or completely grout abandoned utilities. Seal the ends of remaining stubs to prevent piping of soils into the conduits. Page 7 17586-01 February 17, 2010 • Provide for a representative from Hart Crowser to be present during construction to observe stripping and subgrade preparation activities and to identify areas that may require additional removal of unsuitable material. 6.3 Pavement Design Hart Crowser The pavement section can be supported on grade, provided that the underlying subgrade consists of at least 18 inches of densely compacted granular material as described herein, over a reinforcing geotextile fabric. We recommend the following: • Remove the existing pavement section and loose underlying soil to a depth of 18 inches below the bottom of the pavement section. • Compact the exposed subgrade to the extent possible. Since it may be wet, "dead roll" the exposed surface. Avoid compaction with a vibrating compactor as this may significantly disturb soils that are wetter than optimum and cause them to pump. • In subgrade areas that can not be compacted to a dense condition, place a high-strength geotextile fabric (i.e., Mirafi 600x or equivalent) over the exposed subgrade. (The Contractor should be made responsible for the survivability of the fabric.) • Place an 18-inch thickness of imported structural fill consisting of railroad ballast or 2-to 4-inch quarry spalls. The layer will serve as a stable sub-base and a drainage layer. Place the material in maximum 10-inch thick loose lifts and compact it to a dense condition. • If particularly soft areas are encountered, additional overexcavation may be necessary. This should be assessed by the geotechnical engineer in the field during construction. • If subgrade soils are firm and dense when exposed it may be possible to eliminate the fabric and/or use clean sand and gravel fill in lieu of the railroad ballast/quarry spalls. This should be assessed by the geotechnical engineer in the field during construction. • Perform a test section of the subgrade layer prior to placement of the overlying pavement section. The subgrade should be firm and non-yielding when proof rolled, prior to placement of the crushed rock. Based on the results of the test section, it may be necessary to modify these recommendations. Page 8 17586-01 February 17, 2010 • Pavement sections over the prepared subgrade (described herein) may be designed to consist of a minimum of 3 inches of asphalt underlain by at least 6 inches of crushed rock. It should be understood that this pavement section is not based on a rigorous pavement design analysis. It is a typical section that has been successfully used for pavements that experience relatively high volumes of light passenger vehicles and occasional heavy trucks. (e.g., retail parking lot entrances and truck delivery areas.) A rigorous pavement design analysis is beyond our scope of work. We can perform a pavement design analysis if so desired, if we are provided with appropriate input parameters such as traffic volumes, expected design life, etc. 6.4 Curtain Drain Design Hart Crowser We understand that a curtain drain will be constructed along the south edge of the site, to intercept surface and groundwater that flows toward the site from the adjacent hillside. We recommend the following: • Design the curtain drain trench to be at least 2 feet wide and 3 to 4 feet deep. • Place a perforated drain pipe near the bottom of the trench. • Surround the pipe on all sides with at least 6 inches of drainage material. The drainage material should consist of a well-graded (per ASTM D 2487), free draining sand and gravel that contains less than 3 percent passing the no. 200 sieve, based by dry weight on the minus 3/4-inch fraction of the material. Drainage material should be compatible with the perforations in the pipe. • Backfill the trench to the ground surface with the drainage material. • Slope the pipe to a suitable discharge/outlet. • Provide cleanouts that can be accessed from the ground surface at regular intervals along the drain line. The selection of the drainage material is very important. A sample of the proposed material should be submitted and accepted by the project geotechnical engineer prior to its use. Page 9 17586-01 February 17, 2010 6. 5 Site Utilities Site utilities may be supported on-grade, on dense subgrade soils. However, we do not expect dense subgrade soils to be present at the utility invert elevations. We expect that soft/loose site soils will be encountered at the pipe invert elevations. As such, we expect that subgrade improvements will be necessary. We recommend the following: • If dense subgrade soils are not present at the utility invert elevations, overexcavate beneath the structure or pipeline a minimum of 18 inches to allow for the placement of stabilizing material. • Place a high-strength geotextile (i.e., Mirafi 600x or equivalent) at the bottom of the excavation. The fabric width should be at least 4 feet wider than the trench width so it can envelop the sides of the stabilizing materials. (The Contractor should be made responsible for the survivability of the fabric.) • Place at least 18 inches of clean railroad ballast or 2-to 4-inch quarry spalls on the geotextile to stabilize the bottom of the excavation. • Place a thickness of bedding material that is appropriate for the type and size of the pipe. We considered the effect of uplift pressures on buried utilities for those that will be placed below the long-term water level. Based on discussions with Huitt- Zollars, we understand the worst case scenario would be a 60-inch inside diameter (72-inch outside diameter) catch basin with its base bearing 10 feet below the ground surface. For normal conditions with the groundwater level about 2 feet below the ground surface, we have estimated a factor of safety against buoyancy to be at least 1.5. For extreme conditions with the groundwater level at the top of the catch basin, we estimate the factor of safety against buoyancy to be about 1.3. 6.6 Structural Fill Selection, Placement, and Compaction Hart Crowser Structural fill will be required below paved areas, for backfilling overexcavated areas at the bottom of utility excavations, and for backfilling utility trenches and around utility structures. This section includes our recommendations for structural fill selection, placement, and compaction. 6.6.1 Selection of Structural Fill We recommend the following; Page 10 17586-01 February 17, 2010 Hart Crowser • Beneath the pavement section, utility structures, and at the base of utility trenches use railroad ballast or 2· to 4-inch quarry spalls to provide a stable subgrade. • Directly beneath utility pipes, use pipe bedding as appropriate for the size and type of pipe. • In utility trenches more than 2 feet below the bottom of the overlying pavement section, and not under water, use well-graded sand or sand and gravel with less than 5 percent passing the US ,'Jo. 200 sieve by dry weight (based on the minus 3/4-inch fraction). This type of material would generally be suitable for use even during periods of wet weather construction. • If it is necessary to place fill under water, use railroad ballast or 2· to 4-inch quarry spalls. 6.6.2 Placement and Compaction of Structural Fill We make the following recommendations for the placement and compaction of structural fill: • Place structural fill only on dense, non-yielding subgrade soils or on soils overlain by a geotextile fabric as recommended herein and accepted by the on-site geotechnical engineer. • Maintain moisture content within 2 percent of the optimum moisture content, as determined by the modified Proctor test method (ASTM D 1557). • Place and compact all structural fill in even horizontal lifts with a loose thickness no greater than 10 inches. If small, hand-operated compaction equipment is used to compact structural fill, fill lifts should not exceed 6 to 8 inches in loose thickness. • In the upper 2 feet below pavement sections compact structural fill to at least 95 percent of the maximum dry density as determined by the modified Proctor test method (ASTM D 1557). More than 2 feet beneath pavement sections the degree of compaction may be reduced to 92 percent of the modified Proctor maximum dry density. • The compacted densities of all lifts should be verified by testing. The compaction of railroad ballast or quarry spalls may be assessed visually by a qualified geotechnical representative. Any material to be used as structural Page 11 17586-01 February 17, 2010 fill should be sampled and tested prior to use on site, to determine its maximum dry density and gradation. 6.6.3 Use of On-Site Soils as Structural Fill The on-site soils do not appear to meet the criteria presented herein for structural fill and are not considered suitable for use. They may be assessed by the on-site geotechnical engineer during construction. For planning purposes, we recommend that the contractor not rely on the use of on-site soils for any of the structural fill applications. 6. 7 Construction Considerations Hart Crowser 6.7.1 Temporary Excavations Excavations for utility installation may be performed as open cuts provided that the side walls are sloped at a safe angle. However, it should be realized that significant caving may occur in the side walls of an unsupported excavation, particularly below the water level. Because of the many variables involved, actual slope inclinations required for stability in temporary cut areas can only be estimated prior to construction. In general the stability and safety of cut slopes depends on a number of factors, including: • The type and density of the soil; • The presence and amount of water seepage, including rainfall; • The depth of cut; • Proximity of the cut to any surcharge loads near the top of the cut, such as stockpiled material, traffic, structures, etc., and the magnitude of these surcharges; • Duration of the open excavation; and • Care and methods used by the contractor. We recommend the following: • Stability of the temporary slopes should be made the responsibility of the contractor, since the contractor is in control of the construction operation and is continuously at the site to observe the nature and condition of the subsurface. • Require that the contractor make all excavations in accordance with all local, state, and federal safety requirements. Page 12 17586-01 February 17, 2010 Hart Crowser • Protect slopes from erosion by using plastic sheeting as necessary. • Limit the maximum duration of the open excavation to the shortest time period possible. Considering the actual subsurface conditions and the depth of groundwater, relatively flat side slopes may be required. Even with relatively flat slopes, significant caving may occur, especially below the groundwater level. Shoring of utility trenches may be necessary and should be used as determined appropriate by the contractor. 6.7.2 Groundwater Control During Construction We anticipate that groundwater control will be a significant factor during construction, particularly during the installation of deep utility lines and structures. During our field exploration program, we observed the excavation of a test pit at the south end of the site. The test pit was about 6 feet long, 1-1 /2 feet wide and 4-1 /2 feet deep. The test pit side walls generally consisted of silty sand to sandy silt. • At a depth of 3 feet, we observed groundwater seepage into the test pit at a rate of about 1 gallon per minute (gpm). • At a depth of 3-1 /2 feet, caving of the side walls began to occur. • At a depth of 4 feet, groundwater seepage increased to about 3 gpm. Actual groundwater seepage and trench wall stability during construction may be different than observed in this test pit. Actual conditions will depend, in part, on the location of the excavation, soils encountered in the excavation, time of year, length of time that the excavation remains open, and weather conditions. The contractor should be prepared to deal with both surface water and groundwater during construction. As a minimum, we expect that the contractor will need to utilize ditching and sump pumps. Additionally, a well point system may be necessary to control groundwater, particularly for the deeper excavations. The contractor may elect to use other methods as well and should be made responsible for the groundwater and surface water control during construction. Page 13 17586-01 February 17, 2010 7.0 RECOMMENDATIONS FOR ADDITIONAL GEOTECHNICAL SERVICES Hart Crowser Before construction begins, we recommend that Hart Crowser review the final design plans to confirm that our geotechnical engineering recommendations have been properly interpreted and implemented in the design. During the construction phase of the project, we recommend that a Hart Crowser representative observe the following: • Site preparation activities; • Pipeline and utility structure subgrade preparation including overexcavation of unsuitable soils and placement of fabric as appropriate; • Fill subgrade preparation in roadway areas including overexcavation of unsuitable soils and placement of fabric as appropriate; • Placement of structural fill material beneath pipelines and utility structures and beneath pavement sections; • Placement of structural fill in utility trenches and around utility structures; • Placement of drain pipes beneath roadways; • Placement and compaction of the crushed rock; • Fill placement including roadway/embankment construction and utility installation; • Evaluation of the suitability of import soils for use as structural fill or free- draining fill; and • Other geotechnical considerations, which may arise during the course of construction. The purpose of these observations and services is to note compliance with the design concepts, specifications, or recommendations, and to allow design changes or evaluation of appropriate construction measures in the event that subsurface conditions differ from those anticipated prior to the start of construction.

IEE &Gall a 2 Hart Crowser 17586-01 February 17, 2010 APPENDIX A FIELD EXPLORATIONS METHODS AND ANALYSIS APPENDIX A FIELD EXPLORATIONS METHODS AND ANALYSIS This appendix documents the processes Hart Crowser used in determining the nature of the site soils. The discussion includes information on the following subjects: • Explorations and Their Location; • Hollow-Stem Auger Borings; and • Standard Penetration Test (SPT) Procedures. Explorations and Their Location Subsurface explorations for this project include nine hollow-stem auger borings. The exploration logs within this appendix show our interpretation of the drilling, sampling, and testing data. The logs indicate the depth where the soils change. Note that the change may be gradual. In the field, we classified the samples taken from the explorations according to the methods presented on Figure A-1 - Key to Exploration Logs. This figure also provides a legend explaining the symbols and abbreviations used in the logs. Location of Explorations. Figure 2 shows the location of explorations, located by using a tape measure from existing physical features. The ground surface elevations at these locations were interpreted from elevations shown on an electronic survey file tided "15093201VFTR-topo.dwg" provided by Huitt-Zollars, Inc. on February 9, 2010. The measurement method used determines the accuracy of the location and elevation of the explorations. Hollow-Stem Auger Borings Hart Crowser With depths of 14 feet below existing ground surface, nine hollow-stem auger borings (designated HC-1 through HC-9) were drilled on January 21, 2010. The borings used a 3-3/8-inch inside diameter hollow-stem auger and were advanced with a trailer-mounted drill rig subcontracted by Hart Crowser. The drilling was continuously observed by a geologist from Hart Crowser. Detailed field logs were prepared for each boring. Using the Standard Penetration Test (SPT), we typically obtained soil samples at 2-1 /2-foot-depth intervals. The borings logs are presented on Figures A-2 through A-10 at the end of this appendix. Page A-1 17586-01 February 17, 2010 Standard Penetration Test (SPT) Procedures Hart Crowser This test is an approximate measure of soil density and consistency. To be useful, the results must be used with engineering judgment in conjunction with other tests. The SPT (as described in ASTM D 1586) was used to obtain disturbed samples. This test employs a standard 2-inch outside diameter split- spoon sampler. Using a 140-pound hammer, free-falling 30 inches, the sampler is driven into the soil for 18 inches. The number of blows required to drive the sampler the last 12 inches only is the Standard Penetration Resistance. This resistance, or blow count, measures the relative density of granular soils and the consistency of cohesive soils. The blow counts are plotted on the boring logs at their respective sample depths. Soil samples are recovered from the split-barrel sampler, field classified, and placed into watertight jars. They are then taken to Hart Crowser's laboratory for further testing as described in Appendix B. In the Event of Hard Driving Occasionally, very dense materials preclude driving the total 18-inch sample. When this happens, the penetration resistance is entered on logs as follows: Penetration less than 6 inches. The log indicates the total number of blows over the number of inches of penetration. Penetration greater than 6 inches. The blow count noted on the log is the sum of the total number of blows completed ilfler the first 6 inches of penetration. This sum is expressed over the number of inches driven that exceed the first 6 inches. The number of blows needed to drive the first 6 inches are not reported. For example, a blow count series of 12 blows for 6 inches, 30 blows for 6 inches, and 50 (the maximum number of blows counted within a 6-inch increment for SPT) for 3 inches would be recorded as 80/9.

The tests performed and the procedures followed are outlined below. Soil Classification Field Observation and Laboratory Analysis. Soil samples from the explorations were visually classified in the field and then taken to our laboratory where the classifications were verified in a relatively controlled laboratory environment. Field and laboratory observations include density/consistency, moisture condition, and grain size and plasticity estimates. The classifications of selected samples were checked by grain size analysis. Classifications were made in general accordance with the Unified Soil Classification (USC) System, ASTM D 2487, as presented on Figure B-1. Water Content Determinations Water contents were determined for most samples recovered in the explorations in general accordance with ASTM D 2216, as soon as possible following their arrival in our laboratory. The results of these tests are plotted or presented at the respective sample depth on the exploration logs. Grain Size Analysis (GS) Hart Crowser Grain size distribution was analyzed on representative samples in general accordance with ASTM D 422. Wet sieve analysis was used to determine the size distribution greater than the US No. 200 mesh sieve. The results of the tests are presented as curves on Figures B-2 through B-5 plotting percent finer by weight versus grain size.

Pre-screening: When you have the project application ready for submittal, call and schedule an appointment with the project manager (planner) to have it pre- screened before making all of the required copies. The pre-application meeting is informal and non-binding. The comments provided on the proposal are based on the codes and policies in effect at the time of review. The applicant is cautioned that the development regulations are regularly amended and the proposal will be formally reviewed under the regulations in effect at the time of project submittal. The information contained in this summary is subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Planning Director, Development Services Director, Department of Community and Economic Development Administrator, Public Works ~dministrator and City Council). DATE: TO: FROM: SUBJECT: CITY OF RENTON FIRE PREVENTION BUREAU MEMORANDUM December 2, 2009 Vanessa Dolbee, Associate Planner Corey Thomas, Plans Review Inspector Comments for Wonderland Estates Infrastructure Improvements 1. The Renton Fire Department has already met with the applicant on this project, specifically on the water main improvements. A tentative design has been agreed upon. The water is supplied from Soos Creek Water and Sewer district. All water main improvements will be located on private property and so will not impact city or state right of ways. 2. Emergency access shall be provided at all times during installation of all infrastructure improvements. CT:ct wonder DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: November 24, 2009 Vanessa Dolbee TO: FROM: Arneta Henninger If# WONDERLAND ESTATES PRE09-065 SUBJECT: NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-binding and may be subject to modification and/or concurren·ce by official city decision-makers. Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. We have completed a preliminary review for the above-referenced project replacing the existing storm all in Sect. 23 Twp 23 N Rng 5 E. The following comments are based on the pre- application submittal made to the City of Renton by the applicant. Water: • This project is not located in the City of Renton water district. It is located in the Cedar River Water district. The applicant shall comply with the Renton Fire Marshal's requirements. Sanitary: • This project is not located in the City of Renton sanitary sewer district. It is located in the Cedar River Sewer district. Storm: • • • • A conceptual drainage plan and drainage report shall be submitted for this project. The conceptual drainage plan is to include detention and water quality treatment for the fully built out project, including, driveways and roadway improvements. The runoff from the new units must be tight lined into the storm drainage system constructed for the project. The drainage plan is to be first designed per the 1990 King County Surface Water Drainage Manual to determine if detention is required. If detention is required then it shall be designed per the 2005 King County Surface Water Drainage Manuals. Per the proposed FEMA maps this site is located in the 100 year flood plain . The applicant has submitted a narrative proposing 3 alternatives. f Madsen Creek Floodplain analysis and a backwater analysis for all of the alternatives will be required. Alternative 1 proposes discharging to the Madsen Creek in Maple Valley Hwy . Alternative 2, per the applicant, proposes to pump discharge to the Madsen Creek overflow channel located adjacent to the east property line. Note that the adjacent property, the New Life Church has submitted plans for Phase 2. Per the New Life plans submitted there are two existing creek easements (recording number 7201040324 and recording number 9905190312). This project (Wonderland Estates) needs to research the language in that h:lced\planninglcurrent planninglpreapps\09-065.vanessa\pre 09-065 pr comments.doc Wonderland Estates Page 2 of2 easement. Other issu~_that may impact the design of Alt_ernative 2 is the condition of the existing overflow charili~J and what additional improvements will be required. The project needs to show that Wonderland Estates could get permission from the NE Life Church (property owner) to go on their site to do those improvements. The report needs to show that the channel is properly sized to handle the additional flows. , The project will be required to pay the Surface Water System Development Charges of $0.405 per square foot of~ impervious area. This fee is also collected prior to the issuance of the construction permit if there is one or prior to issuance of a building permit. Street Improvements: C • Please note that whenever a building permit is applied for new construction for commercial or alteration of an existing structure in excess of $50,000 then the offslte improvements are required. General: • All required utility; drainage and street improvements will require separate plan submittals prepared according to City of Renton drafting standards by a licensed Civil Engineer. All plans shall be tied to a minimum of two of the City of Renton Horizontal and Vertical Control Network. • Permit application must include an itemized cost estimate for these improvements. Half of the fee must be paid upon application for building and construction permits, and the remainder when the permits are issued. There may be additional fees for water service related expenses.

The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Planning Director, Public Works Administrator, Development Services Director and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available for purchase for $50.00 plus tax, from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov Project Proposal The subject property is located at 14645 SE Renton-Maple Valley Road (also known as Maple Valley Highway). The subject site is currently developed as the Wonderland Estates Manufactured Home Park, since the early 1960's. The existing park has approximately 3DO,OOO square feet of developer impervious surface area. The · proposed project would involve infrastructure improvements that include upgrading the sanitary sewer, water, storm drainage, roadways, electrical systems, and potential upgrading buried telephone, cable, and natural gas utilities. As proposed no additional impervious area would be added, no clearing of native vegetation is planned and no substantial grading is anticipated •. All work is proposed to be within currently developed and/or paved areas. Current Use: The subject site is currently developed as the Wonderland Estates Manufactured Home Park, since the early 1960's. Zoning: The subject site is located within the Residential Manufactured Homes (RMH) zoning designation. The site is also located within the Residential Medium Density Comprehensive Plan designation. The existing use i,s a Manufactured Home Park, which is a permitted use in the RMH zone. Development Standards: The project would be subject to RMC 4-2-llOC, "Development Standards for Residential Manufactured Home Park Zoning Designations". The majority of the RMH development standards would not be applicable because of the nature of the subject Wonderland Estates Infrastructure December 3, 2009 Page 2 of 3 project. As such, the following report only addresses the applicable development standards and/or critical area regulations. Critical Areas: The City of Renton's Critical Areas Maps indicate that the subject site is within the vicinity of seismic hazards, landslide hazards, erosion hazards, protected slopes, wetlands, and a Class 2 stream. • The City of Renton's Sensitive Areas maps indicate the presence of 0 protected slopes" on the subject site. Protected slopes are defined as topographical features that slope in excess of 40% and have a vertical rise of 15 feet or more. In addition, the project is located in an area of seismic hazards, unclassified landslide hazards and high erosion hazards. If any work is planned on a "protected slope" a Variance from the Critical Areas regulations would be required. In any event, a geotechnical report addressing the slope, landslide, erosion, and seismic hazard concerns may be required as part of the review process. The applicant provided a letter from The Watershed Company, dated November 11, 2009, in which, they identified a Cat1:?gories 3 wetland on the subject site. A Categories 3 wetland requires a 25-foot buffer. The City's Sensitive Areas Maps also identify the over flow channel of Madsen Creek as a Class 2 stream, which requires a SO-foot buffer. Further stream and wetland studies may be required as a part of the review process. Because the subject site is developed, .the proposed improvements would fall under the following Critical Area Exemption categories: RMC 4-3-0SOC.5.d.i exc11pts new surface water discharges to wetland Categories 1, 2 and 3, or .Juffers of Categories 1, 2 and 3, and to streams or lakes from detention facilities, presettlement ponds or other surface water management structures; provided, the discharge meets the requirements of the Storm and Surface Water Drainage Regulations (RMC 4-6-030); will not result in significant adverse changes in the water temperature or chemical characteristics of the wetland or stream/lake water sources; and there is no increase in the existing rate of flow unless it can be demonstrated that the change in hydrologic regime would result in equal or improved wetland or stream/lake functions and values. RMC 4-3-0SOC.5.e.ii exempts normal and routine maintenance, operation and repair of existing parks and trails, streets, roads, rights-of-way and associated appurtenances, facilities and utilities where no alteration or additional fill materials will be placed other than the minimum alteration and/or fill needed to restore those facilities to meet established safety standards. The use of heavy construction equipment shall be limited to utilities arid public agencies that require this type of equipment for normal and routine maintenance and repair of existing utility structures and rights-of-way. {ik~, . · ·. :,.· ,. ... : .. · .. ~J,!~!l~f!f;~d ~i~urbe!j,a{~~." •. . uring ar\' '1tntn@fff-Y!JYffter~~e,u.s1:?;0fqin~ct,i9n ~uip91!:?nt. f ·~}.f~j?...;;(g;'_}t1. ~~,,;c.~-· ' "...:r,,l,_i,,%;;fV ,)!,.fi,M!~~-~~{;tt= __ f,_,._, . .,,...,.~-_-1, · ~-,,..,:-./ ,.,, ... ,,fr .. ~;;i,Lf Based on the provided application materials it appears the subject project would meet the requirements of the above Critical Area .Exemptions.

Wonderland Estates Infrastructure Deceml>er 3, 2009 Page 3 of 3 ( Environmental Review: The proposed project may be exempt from Washington State Environmental Policy Act (SEPA) if it meets the exemption requirements for repair, remodeling and maintenance activities (WAC 197-11-800(3)); although, if new pipes over 8-inches are installed SEPA Environmental Review would be required. Permit Requirements: The proposal would require at least two Critical Area Exemptions and potentially Environmental (SEPA) Review. The Critical Area Exemptions would be reviewed in an estimated timeframe of 4 weeks; if SEPA is required, the timeframe would be 6 weeks. There is no application fee for Critical Areas Exemptions although the application fee for the SEPA application is $1,000.00. In addition to the required land use permit, separate construction permits would be required. The review of these permits may occur concurrently with the review of the SEPA and Critical Areas Exemptions, but cannot be issued prior to the completion of any appeal periods. *Once the application materials are complete, the applicant is strongly encouraged to have one copy of the application materials pre-screened at the 6'11 floor /rant counter prior to submitting the complete application package.

(Maple Valley Highway, Hwy 169) in Renton, Washington. It includes: • A summary of the general geology of the area, along with anticipated subsurface soil and groundwater conditions at the site; and • Our opinion regarding the suitability of the site soils for support of roadway pavement sections and buried utilities, stormwater infiltration, and other geotechnical elements of the proposed site improvements. A Vicinity Map (Figure 1 ), Site Geologic Map (Figure 2), and Soil Survey Map (Figure 3) follow the text. THESITE Wonderland Estates is located in western King County on the south side of SE Renton Maple Valley Road (SR 169) at 149th Avenue SE. It is approximately 900 feet (north-south) by 500 feet (east- west), covering an area of approxifl\ately 10 acres. It is a residential community generally consisting ~s>"· of asphalt-paved streets, mobile or modular homes situated on concrete pads, and associated green belts at the edges of the parcel. In general, the' developed portion of the site is fairly flat, sloping slightly downward to the north, ranging in surface elevation from about 120 feet at the south end to 1700 Westlake Avenue North, sune 200 Seattle, Washington 98109-6212 Fax 206.328.5581 Tel 206. 324. 9530 -.. Huitt Zollars, Inc. November 6, 2009 17586-00 Page 2 100 feet at the north end near SR 169. There is an undeveloped hill in the extreme southwest corner of the site that slopes steeply upward toward the southwest SITE GEOLOGY AND ANTICIPATED SUBSURFACE CONDITIONS We anticipate that the project area contains natural deposits from the ice sheets of the Vashon-age glaciation that generally include the following soil units, in descending order from the ground surface downward: • Glacial Drift in the southern portion of the site (References 1 and 2); • Glacial Till across most of the site (References 1 and 2); and • Advance Outwash Sand and Gravel beneath the Glacial Till (References 2 and 3). Glaclal Drift Glacial Drift generally consists of glacially overridden clay, sand, Glacial Till, or unconsolidated recessional deposits. Glacial Till Glacial Till generally consists of dense to very dense sand and gravel in a silt matrix. It often includes cobbles and/or boulders. Advance Outwash. Advance Outwash generally consists of dense, glacially overridden clean to silty sand and can be locally gravelly. Logs of specific groundwater wells (Reference 3) on and adjacent to the Wonderland Estates site correspond fairly well with the mapped geology of the area. Based on our review of this information along with the geologic maps, we anticipate that site soils generally consist of: • Approximately 2 to 5 feet of topsoil or soil fill; over • A variable thickness of dense to very dense Glacial Till across most of the site and clay, sand, gravel, or combinations thereof (Glacial Drift) in the southern portion of the site; over • Gravel (approximate depth to the top of the gravel in the well logs was about 16 feet) We generally expect that the natural soils described above are ~~sent at or very close to the ground surface, although, at some locations, they may be overf'al~ by a few or more feet of soil fill material (Urban Land), depending on past construction and topographic modifications (Reference 4). ,. -.. Huitt Zollars, Inc. November 6, 2009 17586-00 Page 3 Existing well logs indicate the site groundwater level to be variable, between about 4 and 10 feet below the ground surface within the Vashon glacial deposits. PRELIMINARY GEOTECHNICAL ASSESSMENT Pavements. We anticipate that the natural site soils would generally provide suitable support for pavement sections designed for light vehicular traffic. It may be necessary, particularly in areas where the subgrade material is silty or clayey, to provide a soil drainage layer between the natural soil and the pavement section. Also, some densification or treatment ol the natural subgrade soils may be necessary during construction. If fill soil is present at the pavement subgrade elevation, it may be possible to allow fill soils to remain in place beneath pavement sections after some densification. However, this would depend in part on the composition, thickness, moisture content, and density of the existing fill material. Permanent Slopes. We do not expect that there will be any significant cuts associated with the Wonderland Estates improvements. For planning purposes, we expect that permanent slopes in the natural soils up to a few feet high could be cut at an angle of 2 horizontal:! vertical (2H:1 V) or flatter. Buried Utilities. We generally expect the natural site soils to provide suitable on-grade support for buried utilities. Suitable pipe bedding would be necessary. Use of On-Site Soils for Structural Fill The suitability of excavated site soils for use as compacted structural fill will depend upon the gradation and moisture content of the soil when it is placed. As the amount of fines (that portion passing the US No. 200 sieve) increases, the soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. Soil containing more than about 5 percent fines cannot be consistently compacted to a dense non-yielding condition when the water content is greater than about 2 percent above or below optimum. Reusable soil must also be free of organic and other deleterious material. We generally expect that the near-surface site soils, whether natural Glacial lill and Glacial Drift or Fill, will contain significandy more than 5 percent fines. As such, they will tikely be moisture- sensitive. If these soils are wetter than optimum when excavated or construction occurs during wet weather, it will be difficult to compact these soils to a dense condition (e.g., beneath pavement sections or in utility trenches). -- Huitt Zollars, Inc. November 6, 2009 PRELIMINARY STORMWATER INFILTRATION ASSESSMENT 17586-00 Page4 The site is generally underlain by geologic units mapped as Vashon Glacial Till and Glacial Dri~ Glacial Till and Glacial Drift generally contain a relatively high percentage of silty material. Soils with high silt content are generally not considered suitable for stormwater infiltration. In addition, we expect that the water table at the site is located within 4 to 10 feet of the ground surface. Based on this combination of a fairly shallow water table and the presence of soils with a high silt content, it is not likely that stormwater infiltration at the site would be feasible. However, because of the variable nature of glacial soils, areas consisting of relatively dean sand and gravel with the water table deeper than 5 feet may be present. If such conditions do exis~ stormwater infiltration may be feasible. It will be important to complete a field exploration program to identify potential areas that may be suitable for stormwater infiltration.

SCIENCE & DESIGN Per your request. we hawe prepared this letter summarizing wetland and stream amditions noted on the Wonderland Estain Mobile Home Park (Park) during our meeting on October 12. 2009. This Jetta' also addresses environmental permitting requirements as they pertain to the COM!plUal plans for this pn,ject. Site visit findings The property is largely developed with an existing mobile home park and community building and attendant roads, utilities and amenities. Only the southweslem property comer is unimproved. This triangularly-shaped a,rner is steeply sloped and foresled. s,- Madsen Creek. a Oty of Renton-mapped Oaas 2 stream. flows out of an off-sile ravine located south of the subject property. The stream flows into a Mdimentalion pond locabed immedialely south of Park's southern property line. This pond has two outlets; the original stream charvlel and a high-ftow bypaM channel built by King County. The original stream channel flows easterly. then gndually bends north,. eventually bending west and parallel to SR 169. The channel flows aa'085 the front of the subject property for approximalely 225 feet before flowing north beneath SR 169 to its confluenc.-e with the Cedar River. The high-flow bypass channel flows parallel to the eastern propeity line, separated from the Park property by a berm with a grawel road on top. Wet£ands One wetland was noted on the property. This is a slope-type wetland situated at the base of the sloped. folesled area in the southwest property comer. Most of the wetland is within the forested edge, but it appears to extend into lawn areas near the toe of slope, which includes a constructed •duck pond: This wetland appears to meet the Oty of Rentoo Caiegory 3 aiteria, as it is not newly emerging or significantly allered. King County DDFS revealed that this wetland was delineated in the past and the resulting 750 5lxth 5o'Mc 5ood, I Kirkland, WA 98033 p 425.822.52<2 i f 425.8l7.B136 I ...-odco.ccm • • Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page2 delineation report was available to be copied from their files. The report is not available electronically from King County. Critical Habitat Priority Habitats and Species (PHS) data from the Washington Department Fish and Wildlife (WDFW) has not been ordered or reviewed for this project. Salmonid fish use Madsen Creek and possibly inhabit portions of the high-flow byJlll9S channel temponrily during flooding events. No evidenre of endangered, threatened, candidate, sensitive monitor, or priority species was noted during the site visit; however coho salmon and cutthroat trout which use Madsen Creek are state priority species and steelhead, federally-listed as threall!ned, are shown as using Madsen Creek on King County's K,wum Freshulllln Distribution of Stedhead Trout map, along with tabulaled documentation (1994, Karen Walter, Mudcleshoot Tribe). There are no Class 1 (Renton) wetlands on or within dose proximity of the site. Overall Project Scope The Park is in need of infrastnidure improvements. The full extent of improvements are under design review, but are generally thought to romprise the following: 1) Replare existing utilities. 2) Re-route, repair and upgrade existing storm drainage system, including upgrading and/or moving the cunent stormwater outfall. ' 3) Expand the existing sub-surface drainage inlem!ption system at the southern edge of the paved/developed area. The drainage system will tie into the upgraded stormwater drainage system. We understand the current configuration of individual mobile homes and mobile home sites will not be substantially alleied. No clearing of native vegetation is planned and no substantial grading is anticipated. other than necessary for utility and stormwater system upgrades. All work will be within currently developed/paved areas. Expansion of the sub-surface drainage inten'eption system will protect the current paved surfaces and otheJ' infrastructure. The wetland located south of this system is a slope-type and therefore receives hydrologic support from groundwater discharging from the hillside. Sina! the sub-surface drainage intert"eption will be outside and down- slope &om the wetland, it will not affect wetland hydrology. · No direct or indirect impacts to the wetland will result from improving and expanding this system. Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page3 Anticipated Permitting No impacts to intact resources or buffers are anticipaled and therefore environmental permitting for this project is expected to be routine and limited in scope. City of Rtnton Per RMC 4-3-0SOMa, the City of Renton requires a wetland assessment be conducted whenever a wetland is Joc:ated on the subject property. A wetland delineation study is required if the on-site wetland will be impacted by the permitb!d activity. However, subsection b allows the assessment/study requirement to be waived: "when the applicant prwides satisfactory euidence that• road, buiuting or other btnrier exists betr«en the wetland and the propllSed acti11ity, '" when the buffer area needed or required will not intrude on the applicant's lot, '" when applicable data and anJdysis app1opriate to the project proposed exists imd an additiinuzl report is not necessary." RMC 4-3-0SOL3d contains the same code language for streams. RMC 4-3-050 K requires a habitat assessment when Critical Habitats are on or abut the subject property. Critical Habitats are defined as habitats associated with the documented presence of non-salmonid species proposed or listed as endangered, threab!ned, candidate, sensitive, monitor or priority. Caregory 1 wetlands are also Critical Habitats. PHS data should be ordered from WDFW to deb!rmine the presence of species with such status on and near the sire. State ef Washingti,n It is anticipated that upgrading and/or moving the stonnwater outfall on the subject property will require a Hydraulic Project Approval (HPA) from WDFW. Through the state's Hydraulic Cade (RCW 77.55, see also WAC 220-110, Hydraulic Code Rules), WDFW has jurisdiction over activities which occur within the ordinary high water line. Such permits are routinely granted. While it may be preferable to WDFW to discharge stonnwater to the high-flow bypass rather than the main stem of Madsen Creek, discharge to either receiving water body is likely possible from a permitting peupective. Fetlmu The federal government has jurisdiction over Waters of the State, including streams, wetlands and some ditches with connections to navigable waters. This authority is administered by the Environmental Protection Agency as delegated through the U.S. Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page4 Army Corps of Engineers Regulatory Section. Jurisdiction is normally limited to placement of fill or other significant alteration to these waters. Since this project does not involve placement of fill in streams or wetlands, alteration to ditches, or other impacts to waten of lhe state, no federal permitting is required. Based on the limits of this review, It appears the ptuject an likely proceed without a wetland delineation study or wildlife habitat assessment (aldlough PHS data should be ordered~ Stormwater discharge will requite an HPA. but will likely not impose significant difficulty or delay to lhe project.

Mitigation Measures to be Implemented to Minimize: Dust, Traffic, Transportation Impacts, Erosion, Mud, Noise, and other Noxious Characteristics Construction activity at the site will be performed under the regulations described within the Renton Municipal Code. The erosion and sediment control plan shows a silt fence around the northern property line (adjacent to the Maple Valley Highway) and the western property line (adjacent to the Pioneer Place subdivision). Sweeping of the site shall be accompanied by the application of water. Dust control measures such as applying water to exposed areas by spinkling and/or water truck until the surface is wet shall be used during construction. V. Special Hours Proposed for Construction or Hauling No known special hours proposed for construction or hauling are being requested. VI. Preliminary Traffic Control Plan Traffic entering and leaving the site will use the signalized ingress/egress onto SE Renton Maple Valley Road from Maple Drive (private street). Haul hours shall be restricted to the hours between eight-thirty (8:30) a.m. and three-thirty (3:30) p.m., Monday through Friday. Stabilized construction entrances and roads shall be installed at the beginning of the construction and maintained for the duration of the project. Additional measures such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. Traffic signal loops will be preserved. Park residents' ingress and egress will be maintained during construction.

SCIENCE: I, DESIGN Per your request, we have pre~ this letter summarizing wetland and stream conditions noted on the Wonderland Estates Mobile Home Park (Park) during our meeting on October 12,. 2009. This letter also addresses environmental permitting requirements as they pertain to the conceptual plans for this project. Site visit findings The property is hugely developed with an existing mobile home park and community building and attendant roads, utilities and amenities. Only the southwestern property comer is unimproved. This trianguwly-shaped comer is steeply sloped and forested. Streams Madsen Creek. a Oty of Renton-mapped Class 2 stream, Oows out of an off-site ravine located south of the subject property. The stream Oows into a sedimentation pond located immediall!ly south of Park's southern property line. This pond has two outlets; the original stream channel and a high-Oow bypass channel built by King County. The original stream channel flows easterly, then gradually bends north, eventually bending west and parallel to SR 169. The channel flows across the front of the subject property for approximately 225 feet before flowing north beneath SR 169 to its confluence with the Cedar River. The high-Oow bypass channel Oows parallel to the eastern property line, separated from the Park property by a berm with a gravel road on top. Wetlands One wetland was noted on the property. This is a slope-type wetland situated at the base of the sloped, forested area in the southwest property comer. Most of the wetland is within the forested edge, but it appears to exll!nd into lawn areas near the toe of slope, which includes a constructed #duck pond." This wetland appears to meet the Oty of Renton Call!gory 3 crill!ria, as it is not newly emerging or significantly alll!red. King County ODES revealed that this wetland was delineall!d in the past and the resulting 750 Socth St'r'eet South I Kirkland, WA 98033 p .flS.822.5242 'f -425.827.8136 I waten:hecko.com • • Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page2 delineation report was available to be copied from their files. The report is not available electronically from King County. Critical Habitat Priority Habitats and Species (PHS) data from the Washington Department Fish and Wildlife (WDFW) has not been ordered or reviewed for this project. Salmonid fish use Madsen Creek and possibly inhabit portions of the high-flow byp<jss channel temporarily during flooding events. No evidence of endangered, threatened, candidate, sensitive monitor, or priority species was noted during the site visit; however coho salmon and cutthroat trout which use Madsen Creek are state priority species and steelhead, federally-listed as threatened, are shown as using Madsen Creek on King County's Known Freshwater Distribution of Steelhead Trout map, along with tabulated documentation (1994, Karen Walter, Muckleshoot Tribe). There are no Oass 1 (Renton) wetlands on or within dose proximity of the site. Overall Project Scope The Park is in need of infrastructure improvements. The full extent of improvements are under design review, but are generally thought to comprise the following: 1) Replace existing utilities. 2) Re-route, repair and upgrade existing storm drainage system, including upgrading and/or moving the current stormwater outfall. 3) Expand the existing sub-surface drainage interception system at the southem edge of the paved/developed area. The drainage system will tie into the upgraded stormwater drainage system. We understand the current configuration of individual mobile homes and mobile home sites will not be substantially altered. No clearing of native vegetation is planned and no substantial grading is anticipated, other than necessary for utility and stormwater system upgrades. All work will be within currently developed/paved areas. Expansion of the sub-surface drainage interception system will protect the current paved surfaces and other infrastructure. The wetland located south of this system is a slope-type and therefore receives hydrologic support from groundwater discharging from the hillside. Since the sub-surface drainage interception will be outside and down- slope from the wetland, it will not affect wetland hydrology. No direct or indirect impacts to the wetland will result from improving and expanding this system. ·. Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page 3 Anticipated Permitting No impacts to intact resources or buffers are anticipated and therefore environmental permitting for this project is expected to be routine and limited in scope. City of Renton Per RMC 4-3-0SOMa, the City of Renton requires a wetland assessment be conducted whenever a wetland is located on the subject property. A wetland delineation study is required if the on-site wetland will be impacted by the permitted activity. However, subsection b allows the assessment/study requirement to be waived: "when the applicant provides satisfactory evidence that a road, building or other barrier exists between the wetland and the pri,posed activity, or when the buffer area needed or required will not intrude on the applicant's lot, or when applicable data and analysis appropriate to the project proposed exists and an additional report is not necessary." RMC 4-3-050L3d contains the same code language for streams. RMC 4-3-050 K requires a habitat assessment when Critical Habitats are on or abut the subject property. Critical Habitats are defined as habitats associated with the documented presence of non-salmonid species proposed or listed as endangered, threatened, candidate, sensitive, monitor or priority. Category 1 wetlands are also Critical Habitats. PHS data should be ordered from WDFW to determine the presence of species with such status on and near the site. State of Washington It is anticipated that upgrading and/or moving the stormwater outfall on the subject property will require a Hydraulic Project Approval (HPA) from WDFW. Through the state's Hydraulic Code (RCW 77.55, see also WAC 220-110, Hydraulic Code Rules), WDFW has jurisdiction over activities which occur within the ordinary high water line. Such permits are routinely granted. While it may be preferable to WDFW to discharge stormwater to the high-flow bypass rather than the main stem of Madsen Creek, discharge to either receiving water body is likely possible from a permitting perspective. Federal The federal government has jurisdiction over Waters of the State, including streams, wetlands and some ditches with connections to navigable waters. This authority is administered by the Environmental Protection Agency as delegated through the U.S. Wonderland Estates environmental and permitting review Huitt-Zollars November 11, 2009 Page4 Army Corps of Engineers Regulatory Section. Jurisdiction is normally limited to placement of fill or other significant alteration to these waters. Since this project does not involve placement of fill in streams or wetlands, alteration to ditches, or other impacts to waters of the state, no federal permitting is required. Based on the limits of this review, it appears the project can likely proceed without a wetland delineation study or wildlife habitat assessment (although PHS data should be ordered). Stormwater discharge will require an HP A, but will likely not impose significant difficulty or delay to the project.

(Maple Valley Highway, Hwy 169) in Renton, Washington. It includes: • A summary of the general geology of the area, along with anticipated subsurface soil and groundwater conditions at the site; and • Our opinion regarding the suitability of the site soils for support of roadway pavement sections and buried utilities, stormwater infiltration, and other geotechnical elements of the proposed site improvements. A Vicinity Map (Figure 1 ), Site Geologic Map (Figure 2), and Soil Survey Map (figure 3) follow the text THE SITE Wonderland Estates is located in western King County on the south side of SE Renton Maple Valley Road (SR 169) at 149th Avenue SE. It is approximately 900 feet (north-south) by 500 feet (east- west), covering an area of approximately 10 acres. It is a residential community generally consisting of asphalt-paved streets, mobile or modular homes situated on concrete pads, and associated green belts at the edges of the parcel. In general, the developed portion of the site is fairly flat, sloping slightly downward to the north, ranging in surface elevation from about 120 feet at the south end to 1700 Westlake Avenue Nortil, Suite 200 Seattle, Washington 98109-6212 Fax 206.328.5581 Tel 206.324.9530 -.. Huitt Zollars, Inc. November 6, 2009 17586-00 Page 2 100 feet at the north end near SR 169. There is an undeveloped hill in the extreme southwest corner of the site that slopes steeply upward toward the southwest. SITE GEOLOGY AND ANTICIPATED SUBSURFACE CONDITIONS We anticipate that the project area contains natural deposits from the ice sheets of the Vashon-age glaciation that generally include the following soil units, in descending order from the ground surface downward: • Glacial Drift in the southern portion of the site (References 1 and 2); • Glacial TIii across most of the site (References 1 and 2); and • Advance Outwash Sand and Gravel beneath the Glacial Till (References 2 and 3). Glacial Drift. Glacial Drift generally consists of glacially overridden clay, sand, Glacial TIii, or unconsolidated recessional deposits. Glacial Till. Glacial Till generally consists of dense to very dense sand and gravel in a silt matrix. It often includes cobbles and/or boulders. Advance Outwash. Advance Outwash generally consists of dense, glacially overridden clean to silty sand and can be locally gravelly. Logs of specific groundwater wells (Reference 3) on and adjacent to the Wonderland Estates site correspond fairly well with the mapped geology of the area. Based on our review of this information along with the geologic maps, we anticipate that site soils generally consist of: • Approximately 2 to 5 feet of topsoil or soil fill; over • A variable thickness of dense to very dense Glacial TIii across most of the site and clay, sand, gravel, or combinations thereof (Glacial Drift) in the southern portion of the site; over • Gravel (approximate depth to the top of the gravel in the well logs was about 16 feet) We generally expect that the natural soils described above are present at or very close to the ground surface, although, at some locations, they may be overlain by a few or more feet of soil fill material (Urban Land), depending on past construction and topographic modifications (Reference 4). -.. Huitt Zollars, Inc. November 6, 2009 17586-00 Page 3 Existing well logs indicate the site groundwater level to be variable, between about 4 and 10 feet below the ground surface within the Vashon glacial deposits. PRELIMINARY GEOTECHNICAL ASSESSMENT Pavements. We anticipate that the natural site soils would generally provide suitable support for pavement sections designed for light vehicular traffic. It may be necessary, particularly in areas where the subgrade material is silty or clayey, to provide a soil drainage layer between the natural soil and the pavement section. Also, some densification or treatment of the natural subgrade soils may be necessary during construction. If fill soil is present at the pavement subgrade elevation, it may be possible to allow fill soils to remain in place beneath pavement sections after some densification. However, this would depend in part on the composition, thickness, moisture content, and density of the existing fill material. Permanent Slopes. We do not expect that there will be any significant cuts associated with the Wonderland Estates improvements. For planning purposes, we expect that permanent slopes in the natural soils up to a few feet high could be cut at an angle of 2 horizontal:1 vertical (2H:TV) or flatter. Buried Utilities. We generally expect the natural site soils to provide suitable on-grade support for buried utilities. Suitable pipe bedding would be necessary. Use of On-Site Soils for Structural Fill. The suitability of excavated site soils for use as compacted structural fill will depend upon the gradation and moisture content of the soil when it is placed. As the amount of fines (that portion passing the US No. 200 sieve) increases, the soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. Soil containing more than about 5 percent fines cannot be consistently compacted to a dense non-yielding condition when the water content is greater than about 2 percent above or below optimum. Reusable soil must also be free of organic and other deleterious material. We generally expect that the near-surface site soils, whether natural Glacial TIii and Glacial Drift or Fill, will contain significantly more than 5 percent fines. As such, they will likely be moisture. sensitive. If these soils are wetter than optimum when excavated or construction occurs during wet weather, it will be difficult to compact these soils to a dense condition (e.g., beneath pavement sections or in utility trenches). -- Huitt Zollars, Inc. November 6, 2009 PRELIMINARY STORMWATER INFILTRATION ASSESSMENT 17586-00 Page 4 The site is generally underlain by geologic units mapped as Vashon Glacial Till and Glacial Drift Glacial Till and Glacial Drift generally contain a relatively high percentage of silty material. Soils with high silt content are generally not considered suitable for stormwater infiltration. In addition, we expect that the water table at the site is located within 4 to 10 feet of the ground surface. Based on this combination of a fairly shallow water table and the presence of soils with a high silt content, it is not likely that stormwater infiltration at the site would be feasible. However, because of the variable nature of glacial soils, areas consisting of relatively clean sand and gravel with the water table deeper than 5 feet may be present. If such conditions do exist, stormwater infiltration may be feasible. It will be important to complete a field exploration program to identify potential areas that may be suitable for stormwater infiltration. LIMITATIONS OF THIS LETIER Note that this preliminary assessment is based on a brief site reconnaissance, and a review of published geologic information. As per our scope of work, we did not perform field explorations for this work. The information contained herein is preliminary in nature and should not be used for design.
