More particularly, the site is located on the southwest corner of SR-lb9 and 152nd Avenue S.E., on a previously developed site that has an existing church, parking facility, and school hall, including catch basin, collection, and pipe conveyance system draining to a wet/detention pond and biofiltration swale prior to discharge into Madsen Creek. The existing topography of the site is such that the site tends to drain in a northerly direction at a fairly constant rate toward the right-of-way of SR-169, where runoff is collected in a pond prior to discharge to the right-of-way. The existing detention pond will be modified and expanded to provide adequate detention and water quality volume for the existing and new expansion for this project. There is an existing lo�v flow stream passing through the site knor�m as Madsen Creek, which drains a very large upstream basin of 1,790 acres up on the Plateau and Fairwood area of the City of Renton. The low flows from the upstream basin, less than 40 cfs, are routed through Madsen Creek, which passes directly through the center of the site. Flows in excess of 40 cfs are bypassed along the western property line of the proposed development area and course separately from Madsen Creek as it now stands. Please refer to the off-site analysis in Section 3.0 of this report for an exact explanation of the downstream drainage course and upstream basin for this project site. In addition, the upstream basin is further delineated in Section 4.0 of this report as �vell as under the detention sizing criteria information contained within Section 4.0 of this report as well. The 17.5-acre upstream basin contributing runoff to this project site under existing conditions considered to be all forested area on the steep slope on the south side of the project site is still yielding less than 50 percent of the 100-year peak runoff rate compared to the developed site 100-year peak runoff rate even modified to be a smaller area since only a portion of it is being redeveloped; therefore, this upstream basin, which contributes immediately to the project site, not Nladsen Creek initially, can be routed through the detention system and the orifices modified subsequent to the routing. Please see Section 4.0 of this Preliminary Technical Information Report for the sizing criteria used and the calculations performed to size this wet/detention pond for the project site. Some filling in the Madsen Creek floodplain will occur between the proposed wet/detention pond and SR-169. The existing 100-year water surface elevation in this area is 103.26 based on the latest FEMA mapping for the Cedar River and backwater calculations performed on Madsen Creek by this office. This filling will remove approximately 2,608.7 cubic feet of storage in the floodplain which will be compensated by more than enough proposed excess storage in the detention pond. Please see Section �.0.:�of this report for the calculations. 11'06.Ut9.doc �--+ � � � � � L 0 � L..L � r � L � � � King County Department of Development and Environmental Services TECHNICAL INFORMATION REPORT (TIR) WORKSHEET Part 1 PROJECT OWNER AND PROJECT ENGINEER Part 2 PRQJECT LOCATION AND DESCRIPTION Project Owner Church Consultants Project Name Address P.O.

STUDY AREA DEFINITION AND MAPS TASK 1 STUDY AREA DEFINITION AND MAPS The proposed New Life Christian Church is located on a site that is approximateEy 55.14 acres in size located within a por[ion of Sec[ion 23, Township 23 North, Range 5 East, Willamette Meridian, King County, Washing[on. More particularly, the site is located on the southwest corner of SR-169 and 152nd Avenue S.E., on a previously developed site that has an existing church, a parking facility, and school hall. The existing topography of the site is such that the site tends to drain in a northerly direction at a fairly constant rate toward the right-of-way of SR-169. There is an existing detention pond located in the northeast corner of the property, which will be filled in with a new underground detention vault installed in the same location. The Technical Information Report (TIlZ) for the original design for this Renton Assembly of God now known as Renton New Life Christian Church dated February 7, 1992, revised June 3, (993, with a final revision of June 29, 1993, is attached to the TIIt for this new development on the same project si[e. Please refer to that document for a further description of the existing conditions on the project si[e. The proposal for the new development, a portion of which is considered redevetopment of this project site, is to construct a new church building, additional parking with lwo stormwater quality deteniion ponds, one being a pond and one being an underground vault located in the northwest and northeast corners of the project site. The total relief across the site is approximately 75 feet. All existing buildings in this development will remain intact and untouched; however, portions of the existing parking lot will be demolished to construct a new church building. UPSTREAM DRAINAGE ANALYSIS Based on the USGS quad map, our site visit, [he original TIR prepared for this project in 1993, and a topographic survey prepared for the project, it appears that there is upstream fiow onto and through the site. This upstream flow will be divided into two separate basins. The first is the basin from Madsen Creek, which has two separate drainage courses, one for any peak runoff rate less than 40 cfs that tends to course through the site. Any of the peak runoff rate in excess of 40 cfs has its own separate channel based on a diversion structure located at a regional detention and sedimenlation facility located on the southwest corner of the project site. Madsen Creek has an upstream basin of approximately 1,490 acres, and the site itself has an all-woods upstream basin of approximately 17.5 acres. The Fairwood Golf Course consists of part of the upstream basin from Madsen Creek. P(ease refer to the upstream basin maps in this section of the report for a further description of how the upstream basins are configured for this project. In addition, you can refer to the TIR prepared in June 1993 by Urban Design, Inc., which describes the upstream basins in further detail_ i t�o��.002 d«- I I .

Please refer to that document for further descriptions of the existing conditions at lhe project site. • Busin Reconnaissance Sumrnary Reporr: The site is located in the Cedar River Basin. Part of the Cedar River Basin reconnaissance summary report is to construct a channel from Madsen Creek after it crosses underneath SR-169 and courses through on the north side of ihe highway toward the Cedar River. Based on the site visit performed in October 2005, even through the channel is [hickly vegetated it appears that it has been construc[ed. This was done to alleviate floocling in the downs[ream drainage basin. It is difficult to say how much was constructed as the vegetation was so thick that the channel could not be viewed. • Crilical Drainage Area Maps: According [o the water quality applications map and the Z005 King County, Washington Surface Water Design Manual (KCSWDM), Basic Water Quality Treatment is required. According to the flow control applications map, also in the KCSWDM, Conservation Flow Control, known as Level 2 Flow Control, is required as a minimum. • Floodplain u�ul Floodway FEMA Maps: Please see the enclosed Exhibit D—FEMA Map utilize�I for this analysis (Panel No. 984 of 1,725, Map No. 53033C0984 F, revised May 16, 1995). A� indicated by this map, the proposed project dces not lie within a floodplain or floodwayo uf � stream. • Other Off-Site Analysis Repor[s: A review of Cxhibit I — Basin Reconnaissance � Report, and a site investigation was conducted in preparation of this Level 1 Off-Site Ura�na`. Analysis. The U.S. Department of Agriculture Soils Conservation Service soils map is alsu I provided(see Exhibit F). �I • Sensitive Areas Folios: Based on a review of the King County sensitive areas map fo[ios, it was I found that the subject site dces lie within a sensitive area. Madsen Creek is a fish-bearing stream, � the slopes above lhe project site are erosion hazard areas, the stopes above the project site are I landslide hazard areas,and the site is located in a seismic hazard area. • Road Drainage Problems: This is not applicable. • United States Department of Agriculture King County Soils Survey: Based on our review of the soils map for this area, the entire site lies within 1Vewberg and Puyal(up type soits, which are both considered till type soils. • Wetland Inventory Map: The wetland inventory map for this area has been reviewed and it was determined that there are no wetlands inventoried on the project site. An existing wetland on the Aqaa Barn site, immediately east of the project site, is inventoried in the wetland inventory map; however, it was not on the site. • Migrating River Studies: This is no[applicable. t 1706.002.doc A � N � � � � � � � � W Ww EFF[CTIVE DATE(S10F REVISION(S1T0 TH�S PANEL: Revised May 16.1995 to update map format. i 1 � 1 To de�o�rmne II flood insurance is available,contact an insurance age�t or i call the ftai�onal Fbod Insurance Program at(8001 63&6620 I ' 4 j APPROXIMATE SCALE IN FEET i 500 0 50� i � NATIONAL FLOOD INSURANCE PROGRAM FIRM FLOOD INSURANCE RdTF MAP HING COUNTY, WASHINGTON AND � INCORP4R.ATED AR,EAS PANEL 9$4 OF 1125 (SEE MAP tNDEX FOR PANELS NOT PRINTED) � CONTAINS: i COMMUNIiY NUMBER PANEL SUFF�X � - - - i KING COUNTV. j UMINCOAPORATED AHEAS 530077 098d F : RENTON.CITY OF 530088 098A f � f MAP NUMBER ! 53033C0984 f 4G�,�Y�A.,;� MAP REVISED: � � � - MAY 16, 1995 ► � � d c� F �Oa�o o��� I i Federal Emergency Management Agency - ne I 3�Sb3Hlllps � � � N3^b 1Sl,q� � O O Z � y e° �1b r 4 0 h 1S y3 '`��os M �nN�^b H16S1 N a w � �Q lb � r � 'W ez � �� ���� z � . .

SLIMMARY The Low•er Cedar River Basin, in southwest King County, is unique in its development pat- terns and the associated environmental problems thai appear throughout the basin. Eacept for the city of Renton and areas on the Cedar River Valley floor, most of the devetopment in the basin has occurred on the upland plateaus. Most of this development is recent and primarily residential. fn addition, the plateau is the site of numerous sand and gravel mining operations and, in the southern uplands, an abandoned coal mine. Peat is also being mined north of Otter Lake. In some areas livestock are being raised on small farms; there are no major crop-related agricultural activities in the basin. The effects of development are most apparent where storm drainage is routed over the valley walis. Impeivious sudaces oo the plateau 6ave inaeased the rate and volume oE I storm runo[f, resufting in substaatial erosioq siltatioq and f'looding belaw_ In addi- tion, erosion and siltatioo have damaged or destroyed habitat in many tcibutaries, threatenino the survival of fish. Habitat and water quality throughout the basin are also threatened by the filting of wetlands and the presence of laige amounts of domestic tra.sb in some streams. The reconnaissance team noted that the Peterson Creek system has so far remained in its natural, nearly pristine condition. Maintaining this quality should be a high priority in future basin planning capital project programs. Recommendations in the Lower Cedar River Basin inctude 1) designing and mnstructing appropriatety sized R1D and other drainage facilities; 2) estabtishing strictcr laod use policics regarding floodplains, wedands, and p avel mining; 3) conducting mor� detailed and mmprehensive hydreulic/hydiologic analyses of proposed developments; and 4) preventing damage to t6e natural drainage systcm_ The field team also recommends 5) restocing the habitat o[ several tributaries (e.g., cleaning gravels, revegetating stream banks, and diversifyine streambeds for spawning and rearing) as well as 6) protecting thc nearly pristine quality of Peterson Geek. Q. I1V'I'RODUCT[ON: History aod GoaLs of the Progiam In 1935 the King County Council approved funding for the Planning Division (now called the Natural Resources and Parks Division), in eoordination with the Surface Water Management Division, to conduct a reconnaissance of 29 major drainage basins located in King County. The effort began with an initial investigaEion of three basins -- Evans, Soos, and Hylebos Creeks -- in order to determine exisling and potential surface water problems and to recommend action to mitigate and prevent these problems. These initial investiba- tions used available data and new field observations to examine geoloby, hydrology, and habitat conditions in each basin. Findings from these thcee basins ted the King County Council to adopt Resolution 6018 in April 1936, callinb for reconnaissance to be completed on the remaining 26 basins. The Basin Reconnaissance Program, which was subsequently established, is now an important ele- ment of surface water management. The boals of the program are to provide useful data with rebard ro 1) ecitical problems needing immediate solutions, 2) basin characteristics for use in the preparation of detailed basin manaoement plans, and 3) capital costs associated with the earty resolution of drainage and problems. , The reconnaissance reports are intended to provide an evaluation of present drainage con- ditions in the County in order to transmit inCormation to policymakers to aid them in developing more detailed reb latory measures and specific capital improvement ptans. They are noi intended to ascribe in any conclusive manner the causes of drainaoe or erosion P:LC 1 Lower Cedar River E3asin (continucd) problems; instead, they are to be used as initiat sun-eys from which choices for subsequent - detailed engineering and other professional environmentat analyses may be made. Due to the limited amount of time available for the field work in each basin, the reports must be viewed as descriptive environmental narratives rather than as final engineering conclusions. Recommendations contained in each report provide a description of potential mitigative measures for each particular basin; these measures might provide maaimum environmental protection through capital project construction or development approval conditions_ The appropriate extent of such measures will be decided on a case-by-ca.se basis by County o(fi- cials responsible for review�ing applications for permit approva(s and for choosinb amonb competinp projects for public construction. Nothing in the reports is intended to substitute for a more thoroubh environmental and eno neerinp analysis possible on a site-specific basis for anv proposal. QI_ I•'Q�(D�VGS QV LOWER CEDt\R R[VER [iASOV The field reconnaissance of Low•er Cedar River [3asin was condurted in Januarv 1937 hv Robert R. 1=uerstenl�er�, hiolobist; Bruce L. Barker, engineer; and Lee E3enda, beolobist. Their findinbs and recommendations are presented here. /L Overview of Lower Cedar River Basin "Che lower Cedar Kiver 8asin is located in soutf�w•est Kinb Countv and is 27 square miles in area It extends southeast from the mouth oF the Cedar River on l.ake Washington to appro�imatelv river mile 1d.0. The boundarv ro the northeast is marked by a ridretop ronnectinr tlie citv of Renton to Webster and Franklin Lakes; the boundary to the southw•est runs along Petrovitsky Road to Lake Younos. Renton is the only incorporated area in the basin. Other population centers include Fairw�ood, Maptew�ooJ Heights, and Maple Valley. Except for the city of Renton. most oC the residential concentrations are tocated on �he upland plateaus overlookino the Cedar Rever Valley. ?hese up(and developmcnts are recent compared to the smaller established communities on the vailey floor. The basin lies w�ithin portions of three Kin� County planninp areas: Newcasde in the northeast (which includes Renton). Tahoma-Raven Heibhts in the east, and Soos Creek (the laroest of the three) in ihe w�est. Rural areas eaist on the valley ftoor on both sides of the Lower Cedar River, from approximately river mile 5.50 ro 13.00. 'These are fimited to pastureland (or horses, cows, and some sheep and several small "u-pick" fruit and ��egetahle fai•ms. Similar areas are la:ated on the southern uplands abo��e the rearh from river mile 5.50 to 7_00 and in the Lake Desire-Otter Lake area. The plateau is also the site of sand and �ravel mining operations and, in the southern uplands. of the abandoned Fire Kinb Coal Mine. Peat deposits exist west of Lake Desire and north and south of Otter i.ake, and peat minino is being carried out north of Otter lake. Present zoninc allows for urban and suburban densities throu�hout much of the basin, particularly on the upland plateaus and in the Cedar River Vallev from its ntouth to appoaimately river mile 6.$0. Population projei-dons for the year 2000 in the three plannign areas containing the L,ower Cedar Basin <�re over 311,000, an increase of =17 P:I.0 2 Lower Cedar Rivcr Basin (continued) percent from the present. Most of this erowth w-ill occur in the Soos Creek Plannino Area. Dominant geological and geomorpAic features. The oeolopy of the Lower Cedar River Basin is diverse. Geoloaical formations exposed alonb the valley include sedin�entarv rocks, undifferentiated otder biacial drift, extensive ground moraine deposits, recent alluvium along the Cedar River, and landslide deposits alon� the river and its tribu- taries. The sedimentary rocks, composed of moderately dipping sandstones, con- �lomerates, mudstones, and shates, are eaposed localty along the cliffs of the Cedar River Vallev near the mouth of the Cedar Kiver. [n addition, the Renton formation, composed of sandstones, mudstones, and shales with periodic deposits of coal, is also exposed along the lower portion of the Lower Cedar River Valley. Undifferentiated glacial deposits found here are composed o[ three or more till sheets, glacio-fluvial sand and gravel, glacio-lacustrine clay, and sand, and non-glaciat s��nd. ct:ev and thin peat. These lie rner the sedimentary rock formations and are best exposed in cross:section alono the clif[s of the main valley and major tributaries. The morpholob of the Lower Cedar River Basin is dominated by the vallev formed by the Cedar River. Valley walls are steep cli[fs formed by landslides in glaciat sedi- ments. A once e�tensive and meandering River, which created a w-i�te vaNev floor as it cut its way w�estw-ani, the �edar today is diked for most of its length through the tow-er va(ley. A narrow but extensive band of landslide deposits caists aton� the steep cliffs of the main river and its major tril�utaries. Tlte landslide deposits consist of defornied blocks of �lacial sediments and colluvium derived from stid�s or mas.s ftowage. such as landslides and debris flow-s. Recent alluvial deposits fill the valley and major tributaries. Smali, composite, alluvial deb�is lans exist at the mouths of the lar�est tributaries. Closed depressions, prinripalfy in the uplands. have iacustrine and peat deposits. "Che Lower Cedar River Vatley has a high potentiai for erosion due to steep slopes and the existence of a clay layer that promotes soil failures. In addition, the confined nature of tributary channels between steep hillslopes promotes bank erosion durinp hiph flows. Nume��ous recent landslides are evident alono cliffs of manv of the steep tributaries and alona the main stem of the Cedar River. These have been accelented by the remo��al of vegetation and the routin� of concentrated storm flow-s over steep s[opes in areas w�here deve(op,nent has occurred. Hydrologjc and hydrauGc characteristicx. The Cedar River Basin is composed of a complex dr�inage net�+�ork consislino of the Cedar River and 17 tributaries. The larger trihutaries bebin in lakes or weUands on the bluffs and Clow� throurh relativelv tlat. stable c:hannels to the edre of the Cedar River Vallev, then plunge down to the valley fioor throurh steep, erodible ravines. Tributaries of this type such as Tributarv 0�0-1 (w�ith headw-aters at Wetland 3111) and Tributary 0323 (w-hich be�ins at Iake Desire), are found on tlte south side of the Cedar River. Another tvpe of tributary collects surface n�noff from uri�anized areas, pasturetand, and woocied areas. Tributaries 0302, 0307, and 031? are examples of this type of tributarv. "rhey are intermittent (depending on rainfall), shorter in lenath, flow tliroubh shallow•er channels that are steeper at the bluffs and transport more material during times of P:LC 3 Lower Cedar River Basin (continued) high flows. Some of the worst problems located during field investigation (see Appendia C for a ful! listing) occur on this type of tributary. Catchments 5, 6, and 12 have very infiltrative soiis. Urban developments hvae utilized R/D poinds to efEectively infittrate ali ufian runoff before it reaches the valley hilistopes_ The infiltrated runoft then reappears as springs. Two large lakes {Desire and Otter), togetfier with four smal[er ones (Shady, Peterson, Webster, and Francis) lie in the sou[heast third of the basin. Numerous large wetland areas exist in this section as well. The field team identified 20 potential wetland sites that had not been previously identified in the Sensitive Areas Map Folio (SAMF). The system of lakes and wetlands in this area effectively buffers the high flows draining to these tributaries. Habitat characteristics With few exceptions, usabie fish habitat eaists only in peren- nial streanis (i.e., Trib. 0302, 030=1, 0305, 0323, and possihly 0303). In other streams (e.g., Trib. 0�03 and 0310), steep gradients prectude fish use. Steep gradien�s also re�2uce fish use in the p�;rennial systems (except for Trib. 032ti). Habitat is in various staaes of debradation in these svstems; pools are being filled and bravets and debris shift reb larty. [n Tributary 0323 (Peterson Creek), however. habitat diversity is extensive, and the channei is not seriously degraded. At this la:ation the field team observed at least three species of salmonoids. In beneral, the most diverse and least disturbed habitat in a tributary system occurs in the larbe w�etland areas in the southeast third of the basin. Usable habitat for anadromous fish is found in the low-gradient portions of streams where channels cross the Cedar River Valley ftoor. In these reaches, how•ever, onty spawning habitat is likely to he avaitable, as the poots and woocly debris necessary for successful rearin� either do not exist or are quite timited. Excellent spawning and rearinr areas exist w•here pools and riffles are eztensive, instream cover and bank vebetation are intact, and diversity of habitat types is abundant. B. Ef[ects of Ucbani7atioo in t6e Basin Floaiin�, erosion, and the degradation of habitat associated with development in the Low�er Cedar River Basin are most apparent where devetopment has eliminated vege- tation alon� the edges of the valley and where stormwater has been routed down channels and swa{es. The removal of vegetation, such as trees, above and betow the edges of valley waUs, as weli as the discharbing of stormwater over the valtey wall, has res�dted in tension e:rarks and landslides that are endangerin� some houses_ The sedi- ments from these failures are depositing in sireams and on va(ley floors and damaD�nb fish habitat and private property. Discharoino stormwater from incieased impervious areas into steep tributary channels and swales is seriously destabilizing channels and valley w-alls; tliis in turn results in channel downrutting, bank erosion, and landslides_ 1�he sediments from these problems often degrade fish habitat and settle oui on pri- vate property alonb the valley floor. Two serious instances of development-related erosion occurred during the November 1936 stonn: I) culverts reroutin; the stream were plu�ed, causing the formation of a new channe! that destroyed portions of roads on Tributary 03I4; and 2) new, uncom- P:LC 4 Lower Cedar River Basin (continued) pacted fill adjacent to new residences near coltection point S was washed partly away durinb the storm, causing landsiiding and b ilying_ Future problems will be similar to these, as commercia! and residential developments increase fiow rates and volumes by decreasing natural storace and infiltration. This is expected to occur if wetlands on the upper plateau are eocroached upon or lost (e.b., on Trib_ 0304 at RM 2_30 and on Trib_ 03o�tA at Rm I.bO). "The preservation of wetlands and streambank vegetation and the attenuation of storm flows are esscntial in this basin. G Specific Prob{ems Ideotified The steep valley sidestopes through which streams pass and the often dense upland development resuit in a number of similar problems that repeat themselves throughout the Low•ec Cedar River Basin. The most sionificant of these are outlined and discussed bclow-. 1. Uraioagc and flooding probleras are oftea the result of scveral conditioos: a. Uodcrsized cuberts aad inadequate entraace structures� The most notahle area is on Tributary 030fi at river mile .30, w-here a culvert here w�as blocked by debris carried dow•nstream bv the stre'�m and caused erosion and floodinb of Faicw�ooci Golf Course. The bla:kage was compounded by the fact that the culvert was undersized; the problem wilt worsen as fiow•s increase from upstream deve(opment. b. Scrious iastream erosion and subsequeot dowastrcam sedimentation_ These have been caused by three main factors: 1) runoff fro�n r�sideniiat developments on the bluffs above the valley, 2) compacted pasturetand due to livestock, and 3) runoff from impe�vious areas oribinatinb at �rave! pits. "I'hese problems witl continue and worsen unti! mitioative measures are taken. (See Appendix C for specific eaamples.) c. Uodersized rechanne[ized streams. Tributaries on the valtev floor are too sma(I to carry the increased flows oribina�ino in developed residential areas along the top o[ the bluffs_ For example. Tributary 0�02 at river mile .?5, �he channel alonb Maplewood Ciolf Course, overtops and [loods durin� SIOI"II1S. d. Coastruction ia wettand and floodpiain a�+eas, Manv of the w�etiands on the south side of the Cedar River are peat bors, and roads built through them continue to settle each year, increasin� the amount of Cfooding on the road_ 1=or example, the road crossing with Tributary 0�2.4B north of Lake Desire will experience more severe floodinb as the mad settles. c_ Discharging of stormwater at the top of steep banks At river mile ?.20 on the Cedar River, a trailer park (constructed on the edge of tlie cliff) disc:harges its drainage down the vailey v`all. lncreased flow-s erocie the steep vaqey, depositing sediments on the valley ftoor, blockinb channets and causing floodin�. These problems will e��entuallv stabilize, but only aftec a laroe yuantity of soil has been eraied. P_LC 5 L,ower Cedar River I3asin ' (continued) 2 Damage to property is being caused by three factors: a_ landslidcs and poteotial laadslides. Landslides are acceleratcd by the removal of vebetation on steep slopes in preparation for residential construction and/or by the routing of storm f{ows over hilislopes. For example, a large landslide has already occ:urred in the front yard of a resi- dence on the Cedar River at river mile 7.80. b. Seclimentation (from landslides). Sedimentation and channel and bank ero- � sion are damaging private property alonb the vafley floor (Trib. 0299 and , 0310). c. I•loodiog during storms� Flooding has heen brou�ht on bv the effects of development and assoc-iated chanbes to tlie natural drainage systems in the basin. (See "B" above_) 3_ De:stnection of habitat is being caased by four conditions: a. Sedimentation of pools and riffles and oementing of graveL� These proUlems, the result of severe erosion and the transport of bedload material, have been caused bv upland developments in the basin and the presence of associated impervious surfaces, w-hich increase the rate and yuantity o( surface runo[f. Sedimentation and cementin� oC oraveis in streambeds destroy naturat spawnin� and rearino habitat_ On Tributa�y 0307 at ri.�er mile .40 and Tributarv 030$ at river miles .95, 1.20, and 1.70, recent high flow-s have erocied the streambed at least one foot, contributina to a serious silta�ion problem downstream_ Heaw bedload transport is evi- dent in all systems o[ the hasin except 7-ributarv 0333. ln Tributarv 0�03 at river mile .?5, fine sediments are accumulating in gravels that may be used by resident fish. In Tributary Oi04 between river miles .95 and 1."�0, pools are being filled by sands and gravels and rearing habitat is heino rapidty lost. b. Channeli7atioa of stream bed�. C.oss of habitat throunc �hannetization has ocrurrcd in all the major streams of ihe basin, but most noticeably in those reaches �hat cross the vallev floor. These reaches lark habitat diversitv. reducin� fish u.se for spawnino and rearinb. Channelization has damaged or destroved habitat in several reaches that w•ere once heavilv used bv fish: the.se include Tributary 030? betw�en river mile .30 and a0, Trirularv O.W betw�een river miles .OS and .I4. Tributarv 0305 betwee� river mile .20 and .75, and Tributarv 0�33 from river mile 1.10 to 1.40_ These svstems cannot afford a furtlier reduction of habitat and slill remain viable fisherv resour- res. c_ 'Thc aocumulation of trash in stream beds. This problem occurs in close proximity to residential areas. Trash decrades water yualitv and is visuallv unpleasant. Tires, appliances, furniture, and other trash have been throw�n into Tributarv 030? at river miles 1.00 and 1.10 and in Trii�utarv 0�0� at river mile .35. P:LC 6 Lower Cedar River Basin (continued) d. Wetland encroachment. Encroachment destrovs habitat and eliminates natural water filtration and storabe for surface runoff. Examples of this problem ":ere obsecved on "1'ributary 0304 at river mile 2.30, Tributary 0:03 at .30, and Tribu�ary 030-IA at river mile 1.80. Many wettands have already been completely lost throuoh filling, for example on Trihutary 0306A at river mile .55. Suspected violations were foiwarded to Suildin� and L.and Development for enforcement. IV. RECON+�iENDA"I'IONS FOR ACI"ION The prima►y recommendations for action in the Lower Cedar River I3asin addresses current severe problems related to erosion, habitat destruction, and flooJin�. Prevention of these problents w•ilt be acromplished by controllinb tocations and densities of new development and providing adequate R/D facilities for stormw-ater. A Reduce landslide hazards b}r_ 1_ Inctuding scnsitive areas not previously mappod on the Sensitive Areas Map f�olio (SAM�_ See Appendix C for a full [isting of sensitive areas. 2 Fstabli.shiag building setbacks aloog cGffs and native growth protection easements along steep ravines. � 3_ Discouragiag or eliminating the routing of stormwater over ctiffs, unless adequate ti�htline svstems can be constructed ro convey f7ows in a s�ife, nonc:rosive manner to the bot►om of cliffs. 4_ Decmasing peak flows Uy constructinb laroer R/U facilities to Ic:ssen the iandstide and erosion occurrence alono tributary slopes.

Evaluation should heoin with all singie-orifice R/D facilities_ 2_ Coasider areas other thao wetlands as re 'onat storm-detention facililies. � Tributary Q300 at river mile .42 is the si�e for a proposed dam, [or eaample. , 3. Utilize e�dsting lower qua6ty wetlands (those cated other t6an �1) as re�onal storm-dctention facilities. Wellands 3103 and 31�J2 coaid provide more live storace, for example. 4. Review channel and cvMect capacity tor conveying e�sting aod future runoff, and establish flooeiplain areas in regions of sli�ht oradient for existinb and future n�noff ronditions. 5. �'romote the infiltration of surface water ttu�ough the use of �tention facilities aod opcn channels insiead of pipes where the soil and slope conditions pennit.

P:LC 7 [Aµer Cedar River Basin (continued) G Prevent future problems of e�nsion anci flooding wit6 appropriate analysis, planning, and poiicy development retated to surfaee water maoagement_ 1_ Condud a detaikd, eompreheasive 6ydrauGc/hycirologic aoalysis of any propos�ed developmeoLs to determine impacts on the draina�e courses downstream_ This is especially critical for areas on the upper bluffs and plateau, which drain over steep, sensitive banks above the Cedar River. 2 Goaduct a study o[ the impact o[ locating inFdtration poads utitized near the edbe of the bluffs to determine their effect on seepape faces on �he lower face of the bluffs. This mioht be accomplished w�ith a computer-b�sed numerical model of the broundw•ater flow-. 3_ Require the tightlining of storm drainage down steep or sensitive slop� when they cannot be directed away from the slopes. This is done bv pipinc the flow down the stope and discharginc it at the boitom w-ith adequate energy di�.sipation. Many of the intermittent tributaries [lowin� dow�n the l�anks shouW be ti�i�Uined as urban development increases flow to them. 4_ ('�oo.Struct new R/D poods with fdter berms to improve water yuality and reduee finc sedimeot loads. New R/D ponds sliould have two celis w�ith bravel-berm filters and vebetated stiales at the inlet and outlet. Consider Tributaries 0304, 0304A, 030�, and 0303 as sites for this type of facility in order enhance w�ater quality. S. Maintain oatural vegetation on strcambanks anci floociptainS This is especially important for relatively flat channets �lowin� on thc plateau before thev reach the steep bluffs because these channels and their floodplains w-ill attenuate flows durinr times of heavy runoff_ 6. Maintain buffer areas around wetlands. Many of the tributaries on the south side of the Cedar River headwater at wettands. These wetlands act as natural storaae areas durino storms. 7. Reevaluate King Couoty po(icy regarding permitting for gravel mining on steep, sensitive slopes. S. Include t6e city of Rentioo in future intcrlocal agreemcnts for planning and capi- tal improvement projects where city and counrv interests overlap. D. Z;liminate p�+eseot damage to 6abitat and prevent futuee damage by add�s,sing spcci6c problems in t6e stream systems The followinb activities should be coorciinated amono Kinr County, the Muckieshoot Indian Tribe, and State Departments of Fisheries and Game: 1_ Reduce damaging storm tlaws w�ith breater detention volume and lower release rates at upstream developments. 2. Implemeot restoration projects on Tributaries 0�04 (river mile .00-.30), Tributarv 0305 (river mile .20-.30), Tributarv 0303 (river mile 25_35), and Tributarv 03?4 (river mile 1.10 -1.40): r:�c s C,ower Cedar River Basin (continued) a. On Tn�butary 0304: Clean streambed gravels, add habitat and bed-conlrol weirs, and plant bank vegetation for stiade. b. On Tributary 0305: Construct a new channel and mwe stream from road- side channel to its new location on adjacent lands_ Implement a full restoration project to provide channel meanders, habitat structures, pool/riffle enhancement, streambed gravel replacement, and revegetation. c Oa Tn�butary 0303: Move stream from present channel to a location further north, away from the roadside. If relocation is not possible, these minimum steps should be taken: Add habitat structure to eaisting channel with root masses, deflectors, boulder clusters, and other features; revegetate channe! banks with shrubs and small trees; enhance stream crossinbs with bottomless pipe arches. d. On Tributary 0328 (Peterson Creet)_ Add habitat structure by replacing the straight, shortened channel with a moce naturai, meandering one; place habitat structures (such as root masses, deflectors, cover logs, and boulder clusters} throughout the channel; and revegetate banks with shrubs common to adjacent riparian zones (salmonberry, ninebark, or doa ooci, for example}. 3_ Protect t6e Petecs�on Creek system (Tdb. Q328) in its present, near-pristine state_ This will include not only the restoration outlined in section A above, but also the adoption of land use management reo lations to preveni future habitat destruction: a. Protect all e�auing wetlands within t6e subcatchments of Peterson Creek Employ wetland buffers at least 100 feet wide w•ithout e�;ception. b. Restrict dev�ebpment in the critica! 6eadwater area (drainage, habitat, water quality) bounded by Ial�e Desire, Otter Lake, and Peterson [.ake to roral deosities c. Designate aod protect stir,a�ide anaaagemeot zooes of at least lIX} feet from the ordinary high-water marlc (OHWM) along the main stem of the creek. Use 25 feet from the ONWM on tributaries. d. Pt+esecve floodptains and t6eir for�Ls for dynamic retention of sediments and w�ater. e. Restrict vegetation remwat in streamtide/wetland management tiooes. f. Size R/D facilities to store the 100-year storm at a two-to-five-year re{ease rate. Use the two-eell type of pond with a forebay, a gravel filter, and a vegetated swale outffow where feasible_ g. Regulate more dosely all septic tank and drain-Feld instatlatioos, as uell as maintenance schedules, particularly in the Lake Desire, Otter Lake, and Peterson Lake drainage areas.

Fotlowinb the reconnaiss�►nce, 13 projects remain proposed for this area. They include eight new, previously unidentified and unrated projects_ These displace seven previously selected projects, which were etiminated based on the consensus oC the recon- naissance team. Projects were eliminated for several reasons: two sites w•ere anneaed by the city of Renton, tw•o projects were found to be unnecessary, two sites were cateborized as #1 wedands (and are�ineli�ihle), and one project was determined to be infeasible. The previous SWM capital improvement project list for the Lower Cedar River Sasin had an esti- mated cost of S?.710,000, while the revised list increases to an estimated cost of 52,7�,000. This 3 percent inrrease in estimated capital costs is due ro the additioa of projerts after [he reconnaiss��nce. The followin� tabte summarizes the scores and costs for the CIPs proposed for the Lower Cedar River Basin. The.se projects were rated according to previously established SWM Probram Citizen AJviso�v Committee criteria. The projects ranked below are those for which the first rating question, ELEMENT 1: "GO/NO GO," could be answ�ered affirniati��et�.

Based on our review of the drainage complaints from the downstream drainage course, there is considered to be flooding. However, the downstream drainage course lies wi[hin FEMA 100-year floodplain and there is nothing that can be done. The Cedar River raises its banks during the 100-year storm event and it is natural that there would be flooding downstream. 3.1 Conveyance System l�tuisance Problems(Type 1) Conveyance system nuisance problems, in general, are defined as any existing or predicted flooding or erosion that dces not constitute a severe flooding or erosion problem. Conveyance system nuisance problems are defined as flooding or erosion that results in the overflow of the ' constructed conveyance system for runoff events less than or equal to a 10-year event. Examples inctude inundation of a shoulder or lane of a roadway. Overflows colleciing in yards or pastures, shallow flows across driveways, minor flooding in crawlspaces or unheated garages/outbuildings and minor erosion. The downstream drainage course from the this project site, which is the Madsen Creek low flow channel, does experience conveyance system nuisance problems as delineated by the drainage complaints. However, it is not known if the channel has been rechannelized ro provide better conveyance, which was a project that was proposed in the basin reconnaissance summary repoR. If that is the case, then there should be no conveyance system nuisance problems. Since this project is proposing Level 2 Flow Control, no other ftow control measures are required as delineated in Section 123.1 of the KCSWDM. 3.2 Severe Erosion Problems(Type 2) Severe erosion problems are defined as downstream channels, ravines, or slopes with evidence of or potential for erosion/incision, su�cient to pose a sedimentation hazard to downstream conveyance systems or propose a landslide hazard by undercutting adjacent slopes. Severe erosion problems do not include roadway or minor ditch erosion. The sensitive areas folios indicated there were some erosion sensitive areas in the upstream basin; however, there were none in the downstream drainage course. Therefore,this is not deemed to be a problem at this time. 3.3 Severe Flooding Problems(Type 3) Severe flooding problems can be caused by conveyance system overflows or the elevated water surfaces of ponds, lakes, wetlands, or closed depressions. Severe flooding problems warrant additional attention because they pose a significant threat either to health and safety or to public or private property. Based on our review of the drainage complaints, there was flooding in the downstream drainage course and adjacent to the downstream drainage course from this project site, which is very near the Cedar River. This ftooding occurred during 100-year peak storm events, which occurred in 1990 and 1996, and once again after that. The downstream drainage course lies in a floodplain of the Cedar River and it is typical of a floodplain to flood. No further flow control should be proposed for this upstream basin, other than Levei 2 Flow Control, since the downstream I 1706.002.Jcx drainage course occurring immediately downstream of the site exhibited no problems from the drainage complaints or from our site visit. The downstream drainage course investigated by the site visit and a review of the soils map indicates that the downstream drainage course occurs mostly through til! type soils. The field reconnaissance for this off-site analysis drainage report was conducted on October 14, 2005. The skies were overcast and the high temperature on this day was approximately 55 degrees. i t�ob.002.a� � I� TASK 4 � DRAINAGE SYSTEM DESCRIPTION AND PRQBLEM DESCRIPTIONS TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS Runoff teaves the project site in two tocations: one from the eastern developed portion of the site that discharges into a detention pond and, ultimately, into the right-of-way of SR-1G9 where it courses westerly into the Madsen Creek low flow channel, and the second from the western portion of the project site sheetflows due north into Madsen Creek, which courses in a westerly direction, ultimately crossing underneath SR-169 in a northerly direction after coursing on- and off-site a few hundred feet. Runoff then courses in a well�efined channel through thick vegetation, crossing underneath 149th Avenue S.E. in a box culvert, ultimately discharging into the Cedar River afier going through a thickly vegetated area for over 1,000 feet. The following is a review of the drainage complaints and how each one was addressed: Complaint No.93-0944: This complaint dealt with neighbors adjacent to SR-169 and 149th Avenue S.E. complaining that the cuiverts the contractor was installing undemeath the old railroad trai! were too small and might cause flooding. This corrunent no longer applies, as the downstream drainage course does not course through that trail. Complaint No.93-(1992: This complaint dealt with the same thing as Complaint No. 93-0944 and was referred back to tha[ complaint as to how it was addressed. Complaint No.96-1661: This complaint dea(t with silt being deposited from the overflows of Madsen Creek in the downstream drainage course into a backyard. This property owner was referred to Sam Chastain who is the City of Renton Yublic Works superintendent. Complaint No.97-1282: This complaint did not deal with the downstream drainage course from this pro}ect site. Comptaint No.99-0797: The property owner lives adjacent to [he downstream drainage course of Madsen Creek and she felt the creek was going to overtop its banks and flood their property. This was due to sediment deposits in the cllannel and it is not known if the sediment was ever removed. Complaint lYo. 2002-0048: This complaint dealt with flooding in Madsen Creek and the County said that they could not remove the sediment because of fish and wildlife issues. The County no longer has access to the downstream drainage course. All of the drainage complaints for this project have been addressed above. The complaints that dealt with flooding all occuned in the f]oodplain of the Cedar River and there is not �nuch there can be done about that. �t�o�.00z.�� , EXHIBIT K Drainage Complaints nuv. j.

The existing area that will remain undisturbed is modeled based on detention and water quality system previously designed in 1993 matching the 2-year pre-developed peak runoff rate as the release rate during a 2-year/24-hour design storm. In addition the 10-year pre-developed peak runoff rate will be the release rate during a 10-year/24-hour design storm under existing conditions with the pond upsized by 30 percent and the 100- year storm routed through it to check performance. This is consistent with the 1990 King i County Surface Water Design Manual, which the site was initially designed to. The only ' modifications to the existing conditions will be to remove the biofiltration swale and install a weddetention pond in place of the flow control and water quality facilities that exist on the site currently. C. Performance Standards I� Level 3 Flow Control and Basic Water Quality are the flow control and water quality standards instituted for the project except for the existing condition to remain, which matches 2- and 10-year peak runoff rates to the post-developed 2- and 10-year peak runoff rates based on the Santa Barbara Urban Hydrograph (SBIJH) methodology and as is consistent with the 1990 King County Surface Water Design Manual. In addition, the conveyance system capacity standard will be to utilize the Rational Method as developed by the 1990 King County Surface Water Design Manual and still approved by the 2005 King County Surface Water Design Manual D.

There is a large upstream basin contributing to the site, which is conveyed through the site, as well as the existing on-site impervious with its own collection and conveyance system, and the new impervious in the redevelopment portion all drain to one conveyance element that discharges into the pond. A 100-year precipitation of 3.9 inches was utilized and all pipes conveyed the flow without surcharging any manholes or overtopping. Please refer to the following pages of this document for the pipe sizing calculations. Also, backwater calculations were performed on Madsen Creek using the same input data as the previous report by Urban Design did modified somewhat by the new datum (NAVD 88) and latest FEMA mapping for the tail�vater elevation, El. = 102.0. The revised backwater calculations and basin map follow the pipe conveyance calculations in Section S.O.A of the report. Emergency Overflow Spillway sizing calculations are included on the following pages as well. 11706A 19.doc Emergency Overflow Spillway Sizing Calculations .,�..� i_�. � -�j %...i�i .

This floodplain is an existing s���ale, ���hich is �rass-lined and the elevation of the 100-year floodplain in this area is deemed to be ]0326 based on NA�-'D 88 datum. This floodplain is based on a backwater analysis elevation from Madsen Creek, ��-hich courses in a south-to-north direction and backs up runoff between the pond and the highway. The City of Renton is requinng that compensatory flood storage be provided �vithin the pond at the same ele�-ations as the floodplain filling proposed for this development such that since the total ��olume of fill is approximately 2,608.7 cubic feet, an equivalent amount of excess storage has to be provided in the wet/detention pond at the same elevation from approximate ele�-ation 101.5 to 103.26. Cross-sections are drawn and a basin map created �ti�ith stations depicted on it for the floodplain filling area. Also, calculations for the amount of tilling occumng in the floodplain up to ele��ation 10326 and since the pond has excess storage within the live full depth of the pond of 10,174 cubic feet that equates to approximately 1,849.8 cubic feet of excess storage per foot of depth. So there is more excess storage in the pond at the same elevation as the floodplain filling than there is in the floodplain; therefare, please refer to the follo��-ing documents within this section of the report for an analysis of the floodplain fill. as ��ell as the back.��ater calculations for Madsen Creek that depict flood��-ay elevations. This model �vas matched to the prior prepared bac}cw�ater analysis for the floodplain for A-ladsen Creek using a ne�r• datum and a new 100-year floodway elevation of the Cedar River backing up into 1�ladsen Creek on the project site ���hich ' was elevation 102.0 as required by the City of Renton. The same cross-section locations for Madsen Creek���ere used for this analysis as in the pre��ious analysis prepared by Urban Design. i i�ub.oi y.a�� J� .{-�- m�t 4t;� __ �7„ Cap�.��t�Wo� �0� . i � _ �o. --�____ ----- ____ ` '� �� ����!� ' 7 Of i ` �_ ---- ;,. ---- �� - ----- v�i � '� � ' '�� s � — � -��� _ �--- ��:P�,u�;��;�,�o�o�-_---- � z o w�� _ . -- _ —___ t�,�.�.,�,e,� -__ =A p� _. �,�; I �_� �,�,�� v�sr»w � i , '-'�.,�c U,� -. .. _..

PROJECT AND SITE CONDITIONS _ 1.OINTR4DUGTiON This report presents the resul�s of aur subsurface eaploration, geologic hazard, and geotec6nical _ engineering study for the propcued additions to the Renton Assembly of God Church. The proposed addition locations and approaimate locations of the subsurface e�loratioas a�000mplished for this study are preseated on the Site and Ezploration Plau, Figure 1. In the event that any - change in the natvre, design, or locatio�s of the additions is planned, the conclusions and recommendations contained in tfiis report shot�ld be reviewed and modified, or ver�ed, as necessarY- I_1 PurpQse and Scope ; - The purpose of this study was tn provide subsurface data to be utiliz�d in the design and development of the above-referenoed project. Our study included a review of available geologic literature, drilling eaploration borings, and performing geologic stndies bo assess the type, thickness, distribution and physicat properties of the subsvrface sediments and shallow ground water conditions. Geologic hazard evaluations and engineering stvdies were also conducted to _ determine suitable geologic hazard mitigation techniques, the type of suitable foundation, , ailowable foundation soil capacities, antic�ated foundation settlements, retaining wall laberai pressures, floor suppc�rt recommendations and drainage coasiderations. This report summarizes our current field work and offers har.ard mitigat�on aad development recommendatioas based on our present understanding of the project. - 1.2 Auttwrization Authorization to proceed with this study was granted by Mr. Tom Nishunura of Urban Design. � Our study was aocom�lished in genera[ac�cordance with ovr sc�ope of work letter,dated September 24, 1998. Issuance of this report was delayed in order to obtain additional data from the project swveyor, whose work was finaliz�d aft�r our exQloration prog�-am was completed. This report has been prepared for the exclusive use of the Renton Assembly af God Church and their agents, for specific application to this project. Within the limitations of scope, schedule, and budget, our service.s have been performed in accordance with generally accepbed geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, expressed or implied, is made. It mnst be understood that no recommendations or engineering design can yield a guarantee of protection from m�tural slope hazards. Our observadons, findings, and opinions are a means tfl identify and reduce the inherent rist�s to the owner. 2A PROJECI'AND SITE DESCRIPTION T6e project site is that of the existing Renton Assembly, locateci at the southw�st qua,drant of the � intersection of the Maple Valley Highway and 152ad Avenue SE, ia the Renton area of King County. Fa�isting sit8 develapment includes a multi--use building situated on the southern part of the site, with detached portable buildings and a g,zave! parking lot tocated west of the existing _ permaneat build.ing. A large reinforced landscape berm is situat�d south of the existing building, and is designed as a deflection structure tn potential slope failure debris generated ou steep stopes further to the south. North of the existing building, a large asphalt paved parki.ng area is present, - along with surface water manage�nt strudures_ We understand tfiat alt of the existing permanent structures on the site are supported on pile foundation systems. - This report was completed with an understanding of the project based on a preliminary site plan that was based on an as-built plan tided Renton Assembly of God, Site Plan Overall Site, Education Wing, sheet SP-2, with a most recent revision date of July 29, 1997. An untitled updated topographic survey of the site, and the adjacent areas to the south and west was also provided, as were varioas other untided preliminary building addition drawings. Present plans cal� far canstnictio� of two additioris to the existing building. A new classroom addition, measuring approxunately 100 feet north to south an,d 65 feet east to west is pfanned attached to the north side of the e��isting building, on the east part of the site. The classroom addition would _ be located in an area cncrendy occupied by a oourtyard/play area. A large addidon with a complex foatprint s6ape would be located at the west end of the site, attached to the west side of the existing building. The western addition would coasist of a church, classroom, and office . oomplex, with a proposed att�ched chapel as a later phase. The western �ddidon would be constructed in an acea cwrendy occupied by a gravel parking lot,portable buildings, a play area, and undeveloped property. 3.0 SUBSURFACE EXPLORATION Our field study included drilling a series of exploratioa borings in ihe proposed addition areas. We also completed a geologic hazard reconnaissance to surf�cial gain information abo�ut the site. The various types of sediments, as well as the depths where characteristirs of the sedimeats changed, are indicated oa the ezptoration logs preseuted in the Appendix. The depths indicated on the togs where conditions changed may represent gradational variadons beta+een sediment types in the field. If changes occurred between sample intervals in our borings, they were interpreted_ 2 _ Our explorations were,approximateiy lacated in the field by measuring from known site features shown on the preliminary site plans provided to us. - The conclusions and recommendations preseated in this ceport are based on the four exploration borings compieted for this study. The nnmber, location, and depth of the exptorations were completed within site and budgetary constraints_ Because of the nature of exploratory work below - ground, extrapolation of snbsiuface conditions between field eaplorations is�cessary. It shouid be notsd that diffiering subsurface cc>nditions may sometimes be present due to the random nature of deposition and the alteration of topography by past grading and/or fiWng_ The nature and -- e��ient of any variadons between the field exploration�s may not beco� fiilly evident untii eonstruction. If vaziations are observed at that time, it may be neoe.ssary to re-evaluate specifrc recommendations in this report and make appropriate changes. 3.i Exploration Borin�s The exploration borings were completed by advancing a 4:4-inch inside-diameter, hvllow-stem auger with a truck-mountied drill rig. During the drilling process, samPles were obtained at - generally 5-foot depth int�ervals. The barings were continuously observed an�d logged by an engineering geologist from our firm. 'The exploration iogs presented in the Appendix are based on the field logs, drilling action, and inspection of the samples secured. • Disteubed but representative samples were obtained by using the Standard Penetration Test procedure in accorcianc.e with ASTM:D 1586. This test and sampling method consists of driving a standard 2-inch outside-diameter split barrel sampier a dastance of 18 in�ches into the so�I with a 140-pound hammer free-falling a distance of 30 inches_ The mimber of blows for each 6-inch interval is recorded and the number of blows required to drive the sampler the finai 12 inches is knowa as the Staadard Penetration Resistance ("N") or blow count. Tf a total of 50 is recorded within one 6-iach interval, the blow couni is recorded as SO bIaws for the number of inches of _ penetration. The resista�ce, or N value, provides a measure of the relative density of granular soils or the retative consistency of cohesive soils; these vaiues are plotted on the adached boring logs. The samples ob� from the split barrel sampler were classified ia the field and representative portioas placed in water-tig6t containers. 1fie samples were then transported to our taboratory for further visuat classification and laboratory testing, as neoessary. 4.0 SUBSURFACE CONDITIONS Subsurface eonditions at the project site were inferred fram the field explorations acoomplished for this study, visual reconnaissance of the site and review of topography provided on the previously mentioned Gopographic survey. As shown on the fietd togs, the ezploration holes generally encountered man-ptaced fil! material, above older landslide deposits, above recent alluvium,above very dense undifferentiaied gravei deposits. The following section presents more 3 detailed subsurface information organized from the upper(young�st)to the lower(oldest)sediment tyPes- 4 1 Strati�hv Man Placed Fill Three exploration borings, borings EB-1, EB-2 and EB-3, encountered man-plac�d fill above native sediment deposits. 'Ibe fill materia!ranged from approximatety S to 6 feet in thiclmess,a� generaUy oonsisted of Iaose,damp,brown, fine sand with varying silt, gravel,and wood content. Because the fili material was loose with wood debris in boring EB-2, and is �nderlain by unsuitable sediments, this unit is not reoommended as a suitable soil for foundation support. Older Landslide Deposas Below the fill material, boring EB-i encountered very soft/very loose interbedded silt and fuie sand, and trace wood debris. This sedimeni was interpreted as Iandslide�bris t�at originated from stopes to the south. Otl� borings, including boring� EB 2 and EB-3, may also have encountered landslide deposits that were not distinguishable from the recent alluvial sediments in SPT samples_ We re�om�nd that the Iandslide deposits nat be used for foundation support. Recera Alluvium Below the older Iandslide deposits,the man-placed fills, where they were observed in our borings, encountered very loose to loose, gray, fine sand, with varying silt and gravel oontent. This sediment unit was interpreted as recent alluvial deposits associated with deposition from the Cedar River. We recommend that conventional shallow foundations not be supportsd above recent alluvinm or any of the soils and sediments that overlie the alluvium,and that other structures,such as pavement, walkways,or floor slabs, be oonstructed with remedial foundation support measures to reduce settiement potential. _ Undifj`erentiarted Gravel Betow the receat alluvium, our exploration borings generally encountered dense to very dense gravel, with varying silt and sand content. The gravel unit was the Iowest stratigrapluc unit encountered in our exploration borings, and each of ovr four ezploration borings was terminated in this sediment. This gravel unit appears to be either an alluvial deposit or an alluvial reworked ' glacia! deposi� The undifferentiated gravel layer is suitable, in our opinion, for support of deep ' foundation elements as recommended in this report_ 4.2 Hydrolo�v Ground water was encountered in each of our exploration borings. Free groundwater was measured in each baring at the coanpletion of dritling, at depths ranging from approximately 16 to 25 feet below the existing ground surfa,ce. Shallow perched groundwater seepage was observed 4 at depths of approximately 3 to 5 feet in each boring. RTe interpret these ohservations to represent both perched grovnd water, and a more widespread aquifer at depth_ I�we to the short period of tune that the borings remain open, it is likely that actual water levels are shallower than those measured at the tiirbe of drilling. Ground water coaditio�should be expected to vary in response to changes in season, abundance or scarcity of precipitation, loca� changes in surface water management, and �hanges in on and off site developmen� 5 A,pril 7, I999 Project No. KE98433G II. GEOIAGIC HAZARDS AND MITIC ATIONS The following discussion of potential geologic hazards is ba.sed on the geologic, slope and ground aud surface water conditio�as observed and discussed herein_ 'The discussion wili be limited to � hazards associated with earthquake, and iandslide potential. - 5.0 SEISMIC H[AZARDS AND RECOMMENDED MITIGATIOAI Earthquakes axur in the Puget Lowland with great regularity. Fortu�ately, the vast majority of these events are small and are usually not fett by people. However, large earthquakes do occur as evidenced by the 1949, 7.2 magnitnde event and tbe 1965, 6.5 magnitude event. The 19�49 earthquake appears Lo have been the largest in this area during recorded histary. Evaluation of earthquake return rates indicate that an earthquake of the magnitude between 5.5 and 6.O likely will a:cur within the neat 8 to 12 years. Generally, there are 4 types of potential geologic ha7ards associated with large seismic events: 1) surficial ground rupture; 2) seismically inducad landslides; 3) Iiquefa,ction; and 4) ground motion. The potentia[ for each of these hazards to adversely impact the proposed project is discussed below. 5_1 Surficial Ground Ru�ture II Generally, the largest earthquakes thaE have ocCurred in the Puget Sound area are sub-sxustal eveuts, with epicenters ranging from 50 Lo 70 kilometers in depth. For this reason, no surfccial fauiting or earth rupture as a direct result of deep seismic activity has been documented, to date, - in the King County Region. Therefore, based on existing geologic data, it is our c�inion that the risk of svrface rupture impacting the proposed project is low. Surfa,ce rupture can aLso be caused by large total and differential settletnent resulting from seismically induced liquefaction. Liquefaction is discussed in greater detail in Section 5.3. 5.2 Seismically Induced Landslides The steep siopes on the sonth and west sides of tfie west addition pose a risk of iandslide damage to the proposed west additioa Tl�risk is thaE a landslide originating from these slopes could be triggered by a seismic event,and the runout from the slide could damage the additioa. However, Iandsiide risk mitigat�on measures are reoominencled in iater sections af this report, anci the recommended mitigation measures apply to all landslides at the site, regardless of cause. I 6 5.3 Liquefa,ction The existing human-pla,ced fill, landslide debris, and recent alluvium may have significant Iiquefa�ction potential_ However, this report recommends the use of deep foundation systems to support the additions. The deep foundation systems wonid be suppocted on the dense to very dense undifferentiated gravel unit at depth. Altfiough a rigorous liquefaction analysis was not compieted, liquefa�ctioa potential in the vndifferentiaLed gravel is considered low due to the generally coarse grain size and high density of the unit� 5.4 Grovnd Motion Res o� - _ Based on the site stratigraphy and visual reconuaissance of the site, it is our opinion that any earthqualce damage to the proposed structures svpported on a deep fou�dation system as this report recommends would be caused by the int,ensity and acxe,leration associaLed with the event and not any of the above discussed impacts. T!�project should be designed in acoorda�e with seismic guideline,s in the Uniform Bvilding Code (UBC7_ In accordance with UBC Chapter 29, the site is located in Seismic Zone 3, and is characterized ay Soil Profile'I`ype S,E, and a Seismic Zone Factor (� of 0.3�, which results in a Seismic Coefficieut(CJof 0.36. 6.0 LANDSLIDE HAZARDS AND MITIGATI�N The steep siopes south and west of the site were observed during a visual reconnaissance completed in two phases, in October and November, 1998. In general, the slopes south of the existing buiiding were moderately steep,with inclinations of 15 to 35 degrec.s, a�d with localized _ areas steeper than 35 degrees. Several indications of recent or ongoing slc�pe failures were observed on the south slopes, including bowed or "pistol bntted" trees, arcas that had been compietely devegetabed,and areas of soft/toose soil and vegetation interpreted as relatively recent landslide deposits. Although slope geometry of the slopes west of the proposed addition was similar tn the slopes to - the south, overal!slope reiief was less,and indications of past aad ongoing slope movement were generally much tess eviden� The slopes to the west were generalty well vegetabed,and no obvioas accumulations of recent slide debris were present at the base of the slopes. Surficial soil exposures were observed in the sloping areas south and west of the building area. In general,the slopes appear to be composed of interbeddsd sandy silt and silty sar►d, with varying but generally low gravel conten� In areas that had been recendy exposeti by slope failures, the newly e�cpased seciiments were generaily dense to very de�e. At the edges of reoent slope failure scars, the underlying de�e to very dense sediments were mantled by approximat,ely 2 to 4 feet of looser weathered soil and Lopsvil. This upper weathered soil and to�soil appeared to be the source of most of the slide debris when slides occur on these slopes. In general, our observatioas indicate that the recent slope failures south of the existing building have been surficial in nature, generally mobilizing a surficial mass less d�an about 5 feet in � thickn�ess. It appears thai the events have been relatively high energy iQ nature, but that none of the recent failares have tested the landsiide midgatioa berm constructed for the existing building. The sIopes west of t6e proposed addition appear Go have experienced less slope failure activity in the past;however,these stopes must neverthe[ess be ooasidered to represent a risk of slope failure- related damage to the proposed west addition. - The st�eep slopes south of the existing buiiding were a signific�nt co�oe�rn during design of the original project, and a reinforced landscape berm was constructed as a mitigation measure to dsflect and absorb energy of landsiide debris, and reduoe the risk of landslide relabed damage to the bnilding. Similar measnres appear to be warranted f+or the proposed west addition, although, in our opinion, a less elaborate and less oosdy mitigation plan appear� feasible in diis area due to t6e lower overall slope height of the western slopes_ The attached Site and Exploration Plan, Figure 1, indicates die reoommended location for a mitigation wall, in�ended to perfarm th,e same function as the berm does south of the existing building. Detailed geotechnical t�commend,ations for this wall are presented in Section 12.0 of diis report,Landrlidel�litigation Wall_ Based on the proposed building location, aod the eurrent site survey, the proposed plan will result in a coustruction offset from the tce of the steep stope that is generally 50 feet or more, but at the closest point is approximately 20 to 25 feet. In our opinion, with the inclusion of the recommended mitigation wall, the risk of landsIide damage will be reducxd to Ievels similar to ihose associated with standard setbacks without the use of the mitigadon wail. 8 April 7, 1999 Project No. KE98433G III. DFSIGN RECONIIVtENDATIONS 7.0 INTRODUCI70N Our exploration indicates that, from a geotechnical standpoint, the parcxl may be developed with the understanding and acceptanr.e that some risk of earth movement south and west of the site will always be present, which could pobentially impa,c:t the new improvements. The mitigation measures recommended to reduoe risk poteatia! associated with stope failure will significandy - reduce the likelihood of damage to the new additions from slope failures, but should not be considered a guarantee against such occurrenoes. 'Ihe site is generatly undexlain by at least 16 feet of fill, siide debris, and recent alluvium of variable deasity, and with some organic oonten� Such loose and organic rich soils pase a significant risk of future fovndation settlement if d�e new adclitioas were to be snpported on conventional shallow foundadons. Consequendy, deep foundation support is recommended for the struchue. 8.0 S1TE PREPARATION � Site preparation of planned building and road/parking areas should include removal of all �ees, brush, debris and any other deleterious material. Additionally, the upper organic topsoil shouid be removed and the remaining roots grubbed. Areas where loose surficial soils exist due to gnibbing operations should be considered as fill to the depth of disturbance and treated as subsequendy reoommended for structurai fill ptacement. Any eaisting strucdires that are present in the footprint areas of die planned additions should be - demolished and removed from the work azeas. Any buried utilities should be removed or relocated if they are u�er building areas. The resulting depre.ssions should be ba�ckf"illed with structural fill, as discussed under the Structural Fill saction of this report. 8.1 Overexcavation and Filling In Section13.0 of this report,Floor SYipport, different support alternatives are discussed. One of the alternatives includes supporting the tloors of the proposed additio�on grade. If the slab-on- grade support alternative is selected, overeacavation and filling wil! be required within the footprint area of the propose� additioru_ Site preparation of plaitned slah-on-gr�de �loor areas should consist of overexcavating the entire area to a dept6 of 18 inches below the bottom of the pcoposed subslab capillary break layer. The npper 12 inches of the exposed soiLs should then be recompa�cted to 90 percent of ASTM:D 1557. [f organic materiaLt are caposed, they should be further overexcavated Eo firm bearing soils, or we should be contacted to provide additional 9 recommendations. Upon overezcavation to firm bearing soils, the area should then be backfilled to grade wit6 structural fill as discussed in the section on structural fill. 8.2 Temporary Ctit Slopes In our opinion,stable oonstructioa slopes should be the responsbility of the contra�ctor,and shonld be determined during constr�ctioa For estimaiing purposes, however, we anticipate that temporary, unsupported cut slopes in ti�e surficiai fill, slide debris, a� recent alluvium c:an be made at a ma�cimwn s1aQe of 1.SH:1V (Horizontal:V�)_ As is typical with earthwork operatioas, some sloughing and raveling�y occur and cut slo�es may have tn be adjusbed in the field. In addition, WISHA/OSHA regulations should be followed at all times. The site soils should be coasidered 'I�rpe C in accordanoe with WAC 296-155-G64�01. $.3 SiUe Disdubance The on-site soiis contain a high percenhage of fine-grained material which makes t6em moisture- sensitive and subject to disturbance when wet The oontractor must use care during site preparation and excavation operations so that the underlying soils are not softened. If disturbance occurs, the softened soils should be reo�oved and the area shoutd be brought to grade with structura! fill. During wet site or weather conditions, reduced site disn�ption would result if a layer of cn�shed rock surfacing is used in constr�ction a�ccess and staging azeas. If crushed rock is considered for the access and staging areas, it should be nnderlain by engineering shab�on fabric to reduce the potential for fine-grained materiafs pumping up through dze rock and ttirning the area to mud. The fabric will also aid in supporting construction egaipment,thus reducing the amouat of crushed rock required. We recommend that at least 10 inches of crushe� rock be ptaced over the fabric; however, due to the variable nature of t�e near-surface soils and differenc�s in wheel loads, this thickness may have to be adjnsted by the cantractor in the field. - 9.0 STRUCI'URAL FIL,L There is a possbility that structural fill will be neoessary to establish desired grad�s. All references � structural fill in this report refer to subgrade preparation, fill type, placem,ent and comQactioa of materials as discussed in this section. If a percentage of compactiou is specified uader another section of this report, the value given in that section should be used. After overexcavation/stripping has been performed to the satisfaction of the geotechnical engineef/engin�eering geologist, the upper 12 inches of exposed ground should be recompacted to 90 percent of the modified Proctor mazimuon density using AS'T'M.D 1557 as the standard. If the subgrade contains too much moisture, adequaGe recompactioa may be difficult or impossibte to obtain and s�ould probably not be attempted. In lieu of recompaction, the area to receive filI should be blauketed with washed rock or quarry spalls to act as a c�pillary break between the new fill and the wet subgrade. Where the ezposed ground remains soft and further overexcavation is IO impractical, placement of an engineering stabilization Fabric may be necessary to prevent contamination of the free�raining layer by silt migration from below. After recompaction of the exposed ground is tested and approved, or a free-draining rock course is laid, structvral fill may be placed to attain desued grades. Structural fill is defined as n�on- organic soil, acceptable to the geatechnical engi�er, placed in maximum 8-i�ch loose lifts, with - each lift being oompacted to 95 percent of die modified Pra:t,or maximum density using AS'I�i:D 1557 as the standard. In the case of roadway a�d utility trench filling, the ba�ckfil! should be laced and co in accordance with curreni la;al or oodes and s ds. 'I�e tandar _ P � ��Y �P of the compacted fill shaild eatend horizontally outa+ard a minimum distance of 3 feet beyond the locaiion of the perimeter footiings or roadway edge before sloping down at an angle of 2H:1 V. The contractor should note that any prq�osed fill soiLs must be evaluated by Associated Earth Scie�ces, Inc. (AESn prior to their use in fills. T6is wouid requ�re t6at we have a sample of the - materia148 hours in advance to perform a ProcLor test and determine its field compaction standard_ Soils in which the amount of f�e-grai�ed tnaterial (smaller than No. 200 sieve) is greater than approzimately 5 percent(measured on the minus No.4 sieve size)should be considered moisture- sensitive. Use of moisture-sensitive soil in structural fills should be limited t,o favorable dry weather coaditions. The on-site soils generally c�ntained significant amounts of siit and are considered moisture-seasitive. In addition, condstruction equip�nt traversing the site when the - soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained,a select import material consisting of a clean,free-draining gravel , and/or sand shouid be used. Free-draining fill consists of non-organic soil wi� the amount of fine-grained material limited to 5 percent by weight when measured on the minus No. 4 sieve fraction. A representative from our fir�n should inspect the stripped subgrad,e and be present during placement of struct.�ual fill to observe the work and perform a represenrative number of in�lace density tests. In this way, the adeqoacy of the earthwork may be evalnaDed as filling progresses and any problem areas may be coaected at that time_ It is im�portant to understand that taldng raadom compaction tests oa a part-time basis will not assure unif�ormity or acceptable performanace of a fill. As such, we are available to aid the owner in developing a suitable monitoring and ��P��. 10.0 FOUNDATIONS Foundation loads were not available at the time this report was written. The following recommendations should provide general guidance at this stage of the project, however, we recommend that we be allowed to review these[�ecommendations and amend them, as necessary, to t�est coordinate with actual load requirements of ti�e proposed structure_ lt �.1 Aug�ercast Piles Cast in-place concrete piles(Augercast)may be used for foundation support. We recommend tbat - the plac:ement of ali piles be accom�lished by a cantractor ezperienced in their installadon. It should be noted t�at logs,boulders,and other debris could be e�ountered in man placed fill,slide debris, anci recent alluvium. In such cases, it may be necessary to excavate to remove shailow - obstacl�s, adjust pile la�tions to avoid deener obstacles, or imple,ment driiling techniq�s to peneirate the obstructions. Augerc�st piles wi� a minimzun diameter of 18 i�ches will be r,�pable of supporting allowable azia! compressive lo�ds on the order of 40 tons when embedded a minimum distance of 10 f+eet _ into the lower, dense gravel foundation bearing stratum. The depth to the foundation bearing stratum varied in our explorations,and variations should therefore also be expected in pile lengths. Based on the exploration boring data,pile lengt6s on the order of approximateIy 45 feet betow the - ezisting ground surfaoe at the tic�of drilling should be expected below the west addition. Any ch�wges to the existing grade should be a,dded to or subtracted from the pile length,as appropriate_ Pile lengths on the order of approximately 29 feet below the e�cisting gcound surface would be - reqvired in the area of the east addition to achieve the recommended embeddment into the foundation bearing layer, and to achieve the capacity presented above. Allowable design loads may be increased by one-third for short term wind or seisanic loading. Anticipated settlements of - pile supported structures will generally be on the order of one half inch. Allowable axial uplift capa�city of augereast piles that penetrate at least 10 feet into the rec�mmended bearing stratum � should be taken as 15 to�per pile,plus the weight of the pile. We are available to provide design capacitics for different pile diameters, if reqaired. ' 10.1 Lateral Pile Canacity Although the majority of lateral resistance to wind and seismic foading will be generated by the grade beams, the piles will provide an allowable capa�city of 7 tons (applied at the pile top), assumiQg that Ehe piie he�ds are fized against rotation at the ground surface. This lateral load will result in an estimated lateral deflection of 'fi-inch at t�e top of tfie pile. Piles within 10 feet of - another pile along the direction of force should be considerad to be in the zAn�e of influence and the lateral capacity of only on�e of these piles should be used in design If thc Iateral cantrbution of the piles is more ctitical to the practica! design of the structnre, we can provide a comprehensive lateral pile analysis. Such an analysis wauld present laterai pile capacities taking into accovnt the interaction between piles. 10.2 Pile Inspections The actual total length of each pile may be adjusted in the field based on required capacity and oo�litions encountered during drilling. Sinoe completiou of ti�e pile take.s place below ground, t6e judgment and experience of the geotechnical engineer or his fietd representative must be used as a basis for determining the required penetration and aoceptability of each pile. Coasequendy, use of the presented piie capacities in the de.sign requires that all piles be inspected by a qualifiecl geotechnical engineer or engineering geologist from onr firm who can interpret and collect the 12 inshallation data and examine the contractors operations. Associated Earth Sciences, Inc., acting as the owner's field representative, wolild determine the required lengths of the piles and keep records of pertinent instailation data. A finat summary report would then be distributed, following completion of pile installation. - 11.0 LA.TERAL WALL PRFSSURES All backfill behind walls or around fou�on units should be placed as per our recommendatioas for struciural fill and as de.scribed in this section of the report. Horizontally bacicfiiled walls that are free bo yield laterally at least 0.1 percent of dieir height, and d�at are provided with drainage improvements on the backfilled side of the wall, may be designed to resist laberal earth pressure modeled by aa equivalent�uid of 35 pounds per c:ubic foot{pc�. Fully restrai�ed, horizontally backfilled rigid walls that can�ot yield stwuld be designed for an equivalent Ruid of 50 pcf. If parking areas are adja�cent to walis, a svrcharge eq�ivalent to 2 f�eet of soil should be added to the wall height ia determiuing lateral design forces. The lateral pressures present�d above are based ou the couditions of a uniform backfill consisting of either suitable on-site soiLs, or imported sa�d and gravel compacted to 90 percent of ASTM:D 1557. A higher degree of compaction is not recommended as this will increase the pressure acting on the wa[l. A lower compaction may result in settlement of the slab-on-grade, sidewalks, or other structures above the walls. Thus, the compa,ction level is criticat and mast be tested by our firm during placement. Surcharges from adjac;ent footings, heavy construction equipment, or sloping ground must be added ta the above vaiues. Perimeter footing drains should be provided for all retaining walls as discussed under the sectioa� on drainage considerations. , It is imperative that proper drainage be provided so that hydrastatic pressures do not develop against the wall. This would involve installation of a minimum I-foot-wide blanket drain for the full wall height using imported, washed gravel against the walls. 12.0 LANDSLIDE MITIGATION WALL We recommend a structural concrete wall,situated t�etween tfie west addition and the slope to the south and west, be constrvcted to help protect the addition from damage caused by slide debris. The wall should abut the existing berm that was constructed to reduce the risks to the existing building from landslide hazards, aad shouId continue along the south and west side of the addition co a point approximately 10 feet west of the furthest westward extent of �e �dition. The a.pproximate footprint of the walt is shown on the Site and E�loration Plan, Figure 1. 'The landslide mitigation wall should be at least 5 feet in height above the garade oa the uphill side of the wall. The mitigation wall should be designed to witbstand an impact load of 1,000 pounds per foot of watl, plus a lateral earth pressare modeted by an equiwalent f�uid with a weight of 85 pcf, and should be designed to resist a soil levei Eo within 1 foot of the top of the wall during a Iandslide event. T'he impact ioad assumes a soil mass thiclmess of 4 feet at� a flow velocity of 10 feet per second at the wall at the time of slide arrest The resultant of the impact load shouid 13 be applied at the midpoint of the soil zone. The wall could be supported on a shallow foundation, provided that the subgrade for the wall is adequately prepared. Shallow foundaiion preparation should consist of overeacavating and filling, as described in Section 6.0, the Site Preparation section of this report, for preparation slab-on-grade floor subgrades. Provided that the overe�ccavation reoommendations are a�dequately completed, an allowable foundation bearing pressure of 2,000 pounds per square foot shaild be utilized for desig� S�bsequent to a slide event, the catchment behind the wall will have to be cleared of a�ccumnlated debris. 12.1 Passive Resista�ce and Friction Factors Retaining wall or landsli�e mitigation footings cast directiy against undisturbed soils or properly _ compacted structural fill in a trench may be designed for passive resistance against Iateral translation using a.a equivalent fluid equal to 300 pounds per cubic foot (pct). The passive equivalent fluid pressure diagram begins at the bop of the footva�g,how�ver, t,otal latera!resastance should be summed only over the depth of the actual key(truncaLed triangular diagram). This value applies only t,o footings/geyways where coc�crebe is pla�ced directty against t�e trenc� sidewalls without the use of forms. If footings are placed on grade and tfien backfilled, the top of the compacted backfill mnst be horiwutal and extend outward from the f�ooting for a minimum l,ateral distance equal tA three times the height of the backfill, before tapering down to grade. With bacl�ill placed as discussed, footings may be design�ad for passive resistaaoe against lateral translation using an equivatent fluid equal to 300 pcf and the tru�ated pressure diagram discussed above. Passive resistance values inclnde a factor of safety equa! to 3 in order to reduce the amonnt of movement necessary to generate passive resistance. The friction coefficient for footings cast directly on undisturbed,compacted site soils may be t�aken as 0.35. lfiis is an allowabie value and incEudes a safety factor. Since it wil1 be difficult to excavate these soils without disturbance, the soil under the footings must be recompacted to 95 percent of the above-mendoned standard for this value to apply. 13.0 FLOOR SUPPORT Several alternat'rves e�cist for �oor support, depending on what amount of settEement that can be tolerabed. Significani cost considerations are associate�with the selected support option. 'Ihe best floor performance,and highest cost al�tive wauld be to support the floor siabs for the additions on the deep foundation system. This would likely require installation of more and/or higher capaciry piles, grade beams, and pile caps, at increased c�s� Setilement performance of a floor slab supported by the deep foundation system would be equal to the other oomponents of the system. Predicted settlement of a deep foemdation system is li4-inch or [ess total seutement, and one quarter inc6 or less differential sett�emen� Another alternative would be to '�loat" the slab on a thin structural fill mat_ After overezcavating at least 24 inches below finish tloor grade, a strecturai fill mat would be placed. The structural fili mat should be constructed in accordance with the recoiumendations of Sec:tion 6.0, S`tructural Fill. After the fill is compteted and approved, the moisture barrier and free-draining layer may 14 be placed_ "The floor slab can then be cast on top of the free�raining Iayer. 'Il�e floor slab shovid not be tied into the building's foundation but should be free to settle indeQendent of footings. Floating floor siabs shouid contain bar reinforcement to reduce differential movement acrass any cracks which might develop_ Due to the variable site ovnclitions and Hoor loadings, a,ocurate setttement predictions are not possibie. Where littte or no additionaI Ioading will be placed an ttie existing site soiIs,we estimate that seti�ement of lighdy loa�ded "floating" slabs shouid be small. At iocativns where the floor Ioads will be moderate or where a coasidea�able amovnt of fill must be plac�ed b�aztain final gra,de, we estimatie that settlements may be up to 1 t�o 2 iuches. Si�the loading in different-areas of the additions may vary,diffr.�ential settlement of the floor s[ab ardy occur_ The effects of differential settlement can be reduced by the addition of bar reinforcement in the slab, and the slab could be leveled if signifcant settlement does o�ur. Where si�cant amouats of fill are being placed, some reduction in post-coastruction sett�emeats can be achieved by altowing a 1 to 2 month consolidation period prior tQ casting the f�oors. If it is desuable to have floor settlements of less than'k-inch, a floor support�d by piles should be used. Pile supported floors could include either ca�rets cast-on-grade or timber floors with a crawl space beiow. 14.0 DRAINAGE CONSIDERATIONS At the site, the upper soils contain a high perceatage of silt, and are therefore considered moisture sensitive. Theref+�re, traffjc across �ese soils when they aze damp or wet will result in disturbance of the otherwise firm strata. Therefore, prior to si�e work and construction, the coatractor shou[d be prepared to provide drainage as necessary. All retaining and faoting walls should be provided with a drain at t�e grade beam elevation. Drains should consist of rigid,perfiorated,PVC piQe surrounded by washed pea gravel. The level of the perforations in the pipe should be set 2 inches below the bottiom of the grade beam at all locations and the drains should be aonstructed widi suff�cient gradient to allow gravity discharge away from the bnilding. In addition, ait retaining watls should be lin�d with a minimum 12-i�h- thick washed gravel blanket provided aver the fuu-height of the wall, which ties intv the footing drain. Ro�f aad surface runoff should uot dcscharge in�o the footing drain system but shouid be hantiled by a separate, rigid tighttine drain. In planning, ex#erior gcades adjacent to walls should be sloped downward away firom the structure to achieve surface drainage. 15.0 P�OJECT DESIGN AND CONSTRUGTI�N MONITORING At the time of this report, sibe gra�ding, structural planS, and construction methods have not been finalized and the recommendations presented herein are prefiminary. RTe are available to provide additional geotechaicat c�nsulcation as the project design�evetops and possibiy changes from that upon which this r+e{�ort is based. We recommend that Assaciated Eart6 Scieaces, Inc., perform a geotschnicat review af the ptans prior to final design completion. In this way, ovr earthwork and fouadaiion recomm,endations may be properly interpreted and impteme�bed in die design_ 15 - We are also available to provide geotechnical eagineering and monitoring services during construction. The integrity of the foundation depends on proper site preparation and oonstruction procedunes. In addition,engineering decisioas may have Lo be made in the field in the event t6at variations in subsurface conditions become apparen� We are available tn provide construction monitnring services on the project to satisfy King County requirements. We have enjoyed working with you on this study and are confident that these reoommendations will aid in the successful oompletion of yau project.

This review is based on Sheei C 1.0, Site Plan, Renion Assembly of God, Prepared by Denais Batty and Associates, their Project No. 98(�, dated November 15, 1999. The County review contained two com�ents wiEh geotechnical considerations. The first indicaLes that modification of the steep slope cxitical area on the south side of the project is not permitted, except with a varianoe. In our opinion, the landslide � wal� Iocation shown should be considered fle��ible. The intent of the retaining wall is to provide ha�ard mitigation for slope failures on tl�slope to the south. To p�rform this function,the wall should be located as close as practical to the toe of the slope, bui shaild not be constii�cted in sucl�a way that madification of the steep slope itseif is reqvired. If tlie plauned constr�ction would involve intrusion in�o the steep slope bn�ffer area, it may be appropriate to prepare a variance application to atiow the retaiaing wall oo�tion to impm�e on the b�_ Based on the reviewed configeiration, tt�e wall and acce,ss road location cozild be adjnsted so as not to impinge on the sbeep slope buffer. The second issue indicates that it is neoessa�y for tt�ee landslide retaining wall sauth of dre Pmposed building is to be design� to withstand the m�dximum estimated landslide from the slope to the south. Based on previonsiy complet� subs�ufaee exploratiio�s on site, �bris d�posits from several past landslide events were identified.

The proposed retaining wail is designed to withstand a fuwre slope failure on slopes immediately above the new construction that is of equal magnitnde. We therefore conciude that the reqnirement imposed by the County m their seeond geotecheical review comment is met with the current design. It should be noted that if such a slope faiIure were to occnr, it would be necessary to remove the new debris deposited at the base of the slape in or�ler to mainta�in the hazard mitigation function of the retaining wall with respect to future slope failures_ It has been our pleasure to be of contimied service to you on this groject_ Tf you have any questions regarding this letter or other aspects of the project, please do not hesitate to call.

Based on our previous subsurface explorations on siLe, t�e portable classrooms could� be supported on conventional shallow foundations typical ioportafiie classrooms. It is passibk,ba.sed on the seibs�uface conditions,that � shallow foundations could experien�ce minor seul�o�ent over time. Howeyer,portable classroanns that are easily releveled, if needed,do not warrani in�tallation of d�ep fo�ndations,in our opinion In order to relocate ihe portable buildings as planned, it will be necessary to relocate the ezisting . Iandsiide de8ection wall southward appro�imately 10 feet. In our apimon, such a relocation is feasible from a geotechnical standpoint: The new wall shonid be constmcted in accordance with the geotechnical recomnoendations used for initial consh�ction. 9 f I Ffth Av�ue.Swte 100- K�rkland.

(AFSn is pleased to preseni this summary letter for the observation of 18-inch diameter, augercast piles for the Renton Assembly of God Class Room Addition, Phase I, eurrentiy under constraction. Augercast piling construction activities wer-e initiated on October Sth, 2001 and compieted on Oetober 8th, 2001. A total of 43 piling were installed during this time. There were initially 42 piling to be installed, but a below the surface obstruction was encounied, necessitating the insiallation of an additional pile_ Based on our ohservations, the 43 augercast pilings were constructed in general a�ixordance with our writen and verbal recomm�nd�tions and the desigu plans, and specifications as prepared by The Dennis Batty &Associates Group_ It should be noted that the plans were not apprnved by King County and that the construction proceeded-under application review only by King Couniy. Piling installation techniques generally €ol�owed industry practices_. The 18-inch diameter, augercast pilings were all drilled between 25 and 30 feet below pile cap or gracle beam subgr�des, per designt Initially all piling were planned to be 30 feet below g�ade, but a coarse gravel an�� cobble zone thaf hali�ed the drill was encountered at approximaLely 25 fie�below g�rade. � iniermittant pilings were installed at 25-foot depths per AESI_ Onoe the auget reached tt rac�uired depth in each piling location,coacxete sup�Iied by Cadman was pumped down the insic of the a�ger while the auger remained huning in. the drilling-�own direction. The concre appeared at the surface emanating from each boring with appro�cimateiy 5 to 15 feet of aug�; remaining in the ground. The auger was withdrawn at a smooth, slow rate_ The pilings appeazed�• plumb and located in their approximate design loeations_ The locations, both horizontal and vertical, were predetennined by the generat contractor and rechecked by the general contractor- during reinforcement steel bar (rebar) place�ment. Several pilings•were moved slighdy due to _ - 911 FdthAverxie.Siite !00•Kirl3and.wA 98033 • PFione 425 827-7701 •fau 425 827-5924 � interference wiih e�cistiag utilities or encounters wiih subsurface obstructions. The piling were moved with the approval of the designers,The Dennis Batty&Associates Group. The piling pian with dates of installation�of each pile aze attached to this lener. A spiral rebar compression cage was installed in each boring with no•apparent diffic�ilties. Each rebaz spiral cage was smoothly inserted by hand. Cascade Testing was on-site to test concrete and inspect the rebar. The pilings were numbered as they were installed. The�number of each piling, theu zlepths, the amount of concrete nsed for each piling, and any drilling or instaIlation comments were noted each �ay on AESI field reports. Concrete amounts were caculated based on calbrated pump strokes from the contractor's pump. The purnp calibration was supplied by the contrator and was not field checked against delivered amounts. All pilings used more than 100%of their calculated volumes of concrete suggesting that no necking or bridging of the boreholes by the surrounding soils occured. All pilings installed appeared to have been coimpleted �per industry practices, AESI's recomrnendations, and the plans and specificahons by t6e designers, The Dennis Batty & Associates Group_ If you have any qnest�ons, please do not hesitate to call. � Sincerely; ASSOCIATED EARTH S�CIEIVCES, ING ' K'irkisad, Washington . � �`, - • -�.�•�� �,°S rt �R�S�t�,-:,f�� � � � � ,Li ; •��3�`s� •+c� � Q���I . �r J�j_ i A' . <� I Z fl� �$G� s y,�_;j� , � �� �•�,i• � `�1�NAL'�� • - . . � „�-aa� Z � � �-- �.___ John D.

Mr. Tom Nishimura S�bject: Opiaion Concerning Relocated Modular Classrooms Renton Assembly of God Maple Valley Highway King County, WashitzgEon Dear Mr. Nishimura: ' In accordance with your req�est, we have reviewed the pro�d relocation of the modular classrooms from a geotechnical standpoint. The proposed relocation plan was summarized in your site plan and letier of transmittal, dated January 4, 2000. The propo.sed portable classroom relocation was disc�ssed with Todd Hurley of King County DDFS during our January 6, 2000 site meeting. As you are aware, we have been providing geotechnical consiilting services on the Renton Assembly of God sanctuary addition, and other site improvements. We understand that the proposed relocation of portable classrooms would be to an area between the south side of the existing church building and the north side of the existing landslide diversion beran located imu�ediately south of the�chnrch. The area of relocation is currendy a gravel-eovered fire la� measuring some 40 feet in width from �rth to south. T'he three classrooms would be located in this area, with an approain4ate 20-foot setback from the south side of the.eaisting church building. A new fire lane wovid be routed around the south side of the existing diversion berm, along d� diversion berm acc�.s road. We understand that the fue district has reviewed this change and finds it acceptable. From a geotechnical standpoint. it is our opinion that the relocation r� a low risk, considering t6e protection offered to the modular classrooms by the exisEing diversion berm. Malular classrooms can be constructed on conventionai pad foundations in acxordau�ce with the manufacturer's recomme�ations. It may be n�ry to excavaLe into the toe of the slope - forming the northern side of the diversian berm in order to accommodate the modular classrooms. Excavations less than 4 feet in height could be faced with ecology blocks, smailar 3I 1 Fdth Averx.�e.Suiie t0(1-f:ni:land WA 48033 •Ptwne 425 827-770! -fax�25 827-5429 to the existing wall along the eastern margin of the north side of the berm.

As you are aware, I have been tl�e geotechnicai engineer of record on this project�for many years. I will oontin�e as the engineer of record on this addiEion project, even though some of the design information referenced on this project is contained in reports I prepared while working for another'engineering fum_ The original bui�ding was designed and construcLed with both driven timber and drilled augercast pile support to carry t6e moderate to heavy foundation loads. Considering the retatively light fou�ation loads of ihe proposed addition, we feel tha�smaller-diameter pin piles are suitable for foundation support. 2-inch-diameter pin piles should be driven to refnsal as defined by less th�w 1 inch of movement during 1 minvte of su.stained driving by a 9(?-pound jackhammer under the fiill weight of the operator. Piles driven to ihis refusal criterion can be designed to have an allowable vertical compressive capacity of 4,000 pounds per pile. Each pile can be assumed to provide 500 pounds of allowable uplift,provided all pi�e connections are properly welded. All backfill behind walls or around foundation units sho�ild be plac�d as struchnral fill. Horizontally backfilled walls, which are free to yield laterally at least 0.1 perceni of their height, may be designed using a lateral pressure represented by an equivale�fluid e�uai to 35 pounds per cvbic foot (pc�. Fully restrained, honzontally backhlled rigid watls that cannot yieId should be designed for�an equivalent fluid of 60 pcf. . The lateral pressures presented above are based on the co�d.itioris of a unifiorm backh}[consisting of on-site soils compacted to 90 percent of ASTM:D-2557. A hig�er degree of compaction is not recommended as this will increase the pressure acting on the wall. A tower compa�ion may result in settlement of sLrucEm�es supporEed above the walls. Thus, the compadion level is critical and mvst be tested by our firm duri�ug placement. S�rchazges from adjacent foocings, heavy - construction equipment, or sloping grou�must be added to the above values. PernneteF footing drains should be provided for all retaining walls. 91 t FikhAvenue.Suete 100-Kriiarxt WA 98033-Phone�i25 827-770t •fax 425 827-5�124 To resist lateral loads, we recommend the use of passive soil resisiance against the buried portion of pile caps and grade beams. An allowable passive resistance of 200 pcf can be assumed, negieciing the first foot of embedment below grade_ An allowable ba.se friction of 0.35 times the vertical dead load can also be assumed_ The passive resistance and base friciion include a factor of safety of at least 1.5. Slab-on-grade floors shoulc! be supported on either suitable native soils or properly compacted structural fill. A minimum 4inch thickne.ss of pea gravel shoukl be placed beneath the slab tn act as a capillary break. The slab should aIso be protected from dampness by a minimum 10-mil plastic vapor barrier. Ali other recommendations for site preparation, str�ctural fill, and drainage contained in the previous geotechnical repnrts prepared by RiEienhouse Zeman and Associates are still applicabte and are supported by Associateci Earth Sciences, Inc.

The main ch�h building was constructea with a landslide diversion berm immediately south of the existing building. This berm was de'signed to divert landslide debris flows produced from the sleep slopes to tlie south. 'T� berm v►+as intencied to redirect debris flow material around the buiidings to t� east and the west. The proposed �w addition on the west siiie of the e�cisting � building will require some modification of the existing diversion berm_ Specificatly, it appears that the e�cisting berm witl �eed to be extended to the west in order to aecommodate the new addition. Representatives from AESI met with Mr. Todd Hurley of the � King Coanty Deparlment of Development and Environmental Services (DDFS), and presented the conoept of tl�e diversion berm modification_ Mr. Hurley concurred with the pro�sal to . modify the berm and eztend it to the west.

Our recommendations are preliminary in that project plans are stitl under development at the time of this report. Existing and planned improvements within the project area and approximate locations of the explorations accamplished for this study are presented on the Site and Exploration Plan, I'igure l. When final project plans have been prepared, the conclusions and recorrunendations contained in this report should be reviewed and modified, or verified, as necessary. l.l Purpose aad Scope The purpose of this study was tu ��rovide subsurface data to be utilized in the preliminary design of the project. Our study included a revie�v of selected geologic literature, drilling exploration borings, and performing geologic studies to assess the type, thickness, diste-ibution, and physical properties of the subsurface sediments and shallow ground water. Geotechnica[ engineering studies were complctcd to determine the type of suitable foundation, foundation design recommendatious, floor Support recommendations, anticipated foundation and floor settlemcat, and paveme�it and draii�age design considerations. This report summarizes our current fietdwork and offers dcvelopment rccommendatia�s based on our present understanding of the project.

The proposed project will include construction of a new bui(ding, constructing a paved parking tot in the area of the existing gravel parking lot west of the existing building, expanding the existing north parking lot furtlier io the north, and possibly constructing gravet surfacing or paving in the grass field on the nortliwest part of the site. The proposed building will measure approximately 350 by 225 feet in plan view and will include two (evels. The Cinished tioor elevation of lhe lowest leve( is planned to be at clevation 110 fcet. This fi�iished floor elevation is expected to result in minirnal fill ptacement and excavation below existing grade of up Eo approximatety 8 feet ta reach planned finished floor elevation. The site is located at the existing Renton New Life Church_ Tlie existing church includes a huiiding with tinished (loor efevation.s ranging frc�m approximately 118 to 130 feet, portable_ buitdings south of the existing building, a gravel parkin� lot west of the existing building, and a paved parking !ot Eiorth of fhc existinb building. A grass feld is located at the northwest �corner oF the site, is accesse� by a bridge across a creek, and is occasionat(y used as a ear parking area. 3.0 SUI3SUItPACE I;XPLOhA"I,tON Our field study included advancing 11 exploration borings to gain information about che site. `I'I�e various types of sediments, as well as the depths where characteristics of the sediments changed, are indicated on the exp(oration logs �resented in the Appendix. 1'he depths iudicated on dle lags where conditions changed may represent gradational variations between sediment types in the fieid. If changes occurrecf betwee�� sample intervals in our exploration borings, they were interpreted. The approxirt�ate exploration locations are noted on the Site and Exploration Plan, Pigure 1, attached with this report. It shoutd be noted that the exploration borings completed for this phase of work �vere numbered in sequence with other exploration boricigs [hat have previausly bee►� completed on-site by Associated Carth Sciences, Inc. (AESI). We have previously completed tluee exploration borings in an area west of the existing building, ancf one in [he area of the existing east addition. The previously completed borings were useful as bac[cgraund information for this study, but were not within the current project area and are not included with this report. Tlie conclusions and recommendations presented in this repor[ are based on the 11 exploration borings completed for tt�is study. The numbec, locations, and depths oF the explorations were completed within site and budget constraints_ Because of the nature of exploratory work below �;round, extrapolation of subsurface conditions between field explorations is necessary. [t should be noted thai di(fering subsurface conditions may sc�metimes be present due to the Augus[ 24, i005 ASSOC/ATF_D�;IR�If SCIENC/iS, lNC. llVt'Gi!d�KF')H�1.73AZ� P�n�t,rs11�3VJ31l�F_Iti'Y i�1�C 2 Subsurface L:zploralion and Renton New l.ije Churclt Building a�Td Parking Lot Additions Yrelimina�y Geotechnica!Engineerrng Repnn King County, Wushingla� Project a�td Site Conditinns random namre of deposition and the alterati�n of topography by past grading andlor tilling_ The nature and extent of any variations between the field explorations may not become fully evident until construction. if variations are observed at that time, it may be necessary tc� re- evaluate specific recommenclatic�ns in this report ancl make a�pro�riate changes. 3.1 Exptoration Borings "1'he exploralion borinbs were completed by advancing a 4'/4-inch, inside-diameter, h�llow- stem auger with a truck-moun[ed dritl rig. During tlie drilling process, samples were obtained at generally 5-foot-ciepth intcrvals. The exploration borings were continuously observed and logged by a geologisi from our firm. The exploralion logs presented in the Appendix are based on the field logs, dritling action, anct inspection of the samples secured. Disturbed but representative samples were obtained from the ex�laration borings by using the Standard Penetration Test (SP'f) pracedure in accordance wilh American Society for Testing and Materials (AS'I'M):D-1586. This test and sarnpIing �nethod consists of�riving a standard 2-inch, outside,diameler, split-barrel sampler a distance of I8 inclies into the soil with a 140- pound hamrr►er free-falling a clistance of 30 inclies. "Che number of t�lows for eacti 6-inch interval is recorded and the number of blows required to drive the samplcr thc fina[ 12 inches is known as tlle Standard Penetration Resistance ("N") or blow count. [f a total of �0 is recorded wichin one 6-inch interval, tlte blow count is recordect as 50 blows for the correspondi��g number of inches of penetration_ The resistance, or N-value, provides a measure of the relative density of granular soils or the relative consistency of cohesive soils; these vatues are ploued on the attached exploration boring logs. The samples obtaiaed from the split-barre! san�pler were classified in the field and representative portions placed in wa[ertight containers. The samples were then transported to our laboratory for further visual classification. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the field explorations acco�nplishecf for this study and visual reconnaissance of the site. As shown on the fieEd logs, the exploration borings encountered s�bsurface conditions at the exploration locations that were relatively consistent. The existing paving and Eopsoil were typically underlain by loose to rnedium dense, moist silry sand with trace gravet interpreted as ailuvium deposits. Alluvium was deposiled from flowing water and is typically relatively loose. Alluvial deposits are considered suitable for support of paving and lighdy loaded tloor slabs with proper rcmedial preparatio�i. Foundations or other structures with higher loads should not be supported on alluvium uniess it is first improved using GeopiersT"', Rammed Aggregatc Picrs'"', or Rapid Impact Compaction. Augus!

Below the alluvium, our exploratioa borings eucou�itered typically �iense to very dense moist silty sand with graveL This material was interpreted to be an older Vasho❑ or pre-Vashon age deposit tha! has been glacial(y consolidated. At this site, undifferentiated sediments observed in our explorations are considered suitable for support of foundations, floor slabs, or paving. Due to the depth at which the undifferentiated deposits were observed, we anticipate ihat pavements and floor slabs wilf not be directly supported by outwash sediments. We also anticipatc that foundation unit�s wilI have to be supported on GeopiersT�' that derive tlieir support directly from the undifferentiated sediments and alluvivm that have been irnproved with Geopiers�"'. In the explorations that have been completed to date for the ptaruied l�uildinb addition, the etevation of the top of the undifferentiated sediments ranges from approximately 93 to 101 feet. Our observati�ns and interpretations are generally calsistenl with publishe� i�iapping f��r thc si�e vicinity as represented by United States Geologica! Survey Geologic Map of the Renton Quncirangle. King County, Washington, Map GQ-405, by ll.R. 1�1ullineai�x (1965). 'I'his �nap indicates that the site is underlain by alluvial sediments_ Ground water was observed iii our exploration borings a[ depths varying from approximately 10 to 16 feet below tlie ground surtiace at lhe time of drilli►ig. Variations in ground water levels are possibte due to changes in season, weather, on- and off-site land usage, and other factors. [t should be noted that our site explorations are open for only a shc�rt litne, and that actuai ground waler levels might be eloser to the surface than we measured in our explorations. 13ased on the encountered stratigraphy, it is our �pinion that any carthquake damage to the proposed structures when founded oii suitable foundation beari��g strata irl accordance with the recommendations provided in this report wo�ld be c;aused by the intensity and acceleration associated with the event. Design of ihe project shoutd be consistent with 2003 International f3uilding Code (IBC) guidelines_ [n accordanc;e with the 2003 IBC, the fc�llowing values should be used: Site Class "D" (Table 16t5.1.1) Ss = 126% (Figure 1516 (1) S� = 42%a (Figure 1516 (2} Rugt�s! 24, 2(a0.5 ASSCJC/.1TF_'D E�IXTlf SCIl�NC�S, lNC.

Tt�e upper t0 to 24 feei of subsurface materials are loose and will offer support to pavement, floor slabs, and foundatious for lightly loaded anciltary sti�uctures with proper rcmedial preparation. Substantial foundation (oads should be sup�arted on a conventional shallow foe►ndation system constructed above alluvial sedimenls improvec! with Geopiers�"', Rarruned Aggregate Piersr", or soils improved by Rapid Impact Compaction. Pile support of buifding foundation loads is another alternative that was considered, however the three alternativc support types mentioned above were selected during a project team meetii�g, and therefore geotechnical engi►�eering recommendations contained in this report are fc�cused on the project approach that has been selected.

We recommend that, to ihe extei�t possible, the existing paving be used for construction staging. Any excavations below pla►ined �inished grdde for the purpose of demoli[ion or utility relocations should be back�lled with struc[ural fill as described in this report. i Existing topsoil should be remaved from areas where the new bui[ding, paving, or other structures are planned. After topsoit stripping, remaining roots and any other organic debris should be removed fi�om structura{ areas. All soils disturbed by stripping aud grubbing operations should be recompacted as described below for struc[ura! tilf. After site stripping is comptete, existing surficial loose soiis shouId be addressed. In areas where on-grade floor slabs are planned, we recommend excavation as needed to achieve elevations at leas[ 18 inches betow planned floor subgrade. 'fhe resulting surface should be proof-rolled with suitable equipment under the observation of the geotechnical engineer to identify any soft or yielding areas [hat require compaction or further excavation to expose suitable soils. The subgrade shoutd ttien be compacted to at least 90 percent of tlte modified Proctor maximum dry density as determined by the ASTM:D-1557 test procedure for fill more than 4 feet below Cnal grade, and to 95 percent of the same standard for (il! less than 4 feet below finai grade.

Reusing eccavated soil as structural fill witl require significant but unavoidable effort on the part of lhe contractor to dry site soils during favorable dry I weather prior to corn�actio��. The contractor shouid be aware of this and should either inctude costs for drying site soils, or for exporting the excavated site soil and replacing it with imported fil( material as described above. In our opinion, stable construction slopes shoutd be the responsibility of the contractor and should be determined during coi�struction. For estimating purposes, however, we antici�ate that temporary, unsupported cut slopes in the alluvium caii be made at inclinations of 1.SH:i V (Horizonta{:Vertica!} or flatter. If excavation slopes are expcctcd in strucliiral fill, they should be p(aiined at angles of 1.0 to 1.SH:1V. "I'emporary excavaiions into the undifferentiated deposits are not expected because these materia(s were observed 10 feet or more be�ow existing grades. The recommencfed sl�re angles assume ttia[ grou«�l wa[er seepage is not cncouiitered, and that surface water is not allowed [� flu�v acruss lhe temporary slape faces. If ground or surface water is present when the temporary excavatioii stopes are exposed, tlatter slope angles will be reyuired. As is typical with earthwork operations, some s(oughinb and raveling tnay occur and cut slopes may have to be adjusted in the field. In addition, WISHA/OSHA regulations should be followed at a(! times. Most ot� the on-site soils contain substantia! si(t, which makes them highly moisture-sensitive and sul�ject to disturbance when wet. The contractor must use care during site preparation and exeavation operations so that the underlying soils are not softened. [f distucbanee oceurs, ihe softened soils should be removed and the area brought [o grade witli structural fill. The overexcavation and filling process will be least likefy to diswrb silty mois[ure-sensitive soils if excavation is completed with a wide-track hulldozer and fill is placed from an advancing fill pad. Import fil! could be used to construct temporary truck routes an the building pad 2 feet or more above subgrade soils to facilitate truck traffic. In no case should export or import trucks, whee! loaders, or other wheeled equipment be operated on unprotec[ed subgrade soils. If winter construc[ion is expected, crushed rock fi(I could be used to �rovide temporary construction staging areas, if desired. The stripped subgrade shoutd be observcd by the geotechnical engineer, and should then be covered with a geotextile fabric, sueh as Mirafi SOOX oi� eyuivalen�. Once the fabric is �laced, we rccommend using a crushed rock fill layer at teast 10 inches thick in areas where construction equipment wilt be used.

If a percentage of compaction is specified under another section of this report, the value giveri in that scctioi� should be uscd. After stripping, planned excavation, and any r�quircd overexcavation have been performed to the satisfactian of the geotechnical engineer/engineering geologist, the upper 12 inches of exposed ground shou(d be recompacted to 90 percent of the modified Proctor maximum density using ASTM:D-1557 as the standai-d_ If the subgrade contains too much moisture, adequate recompaction may be diffcult or impossible to obtain and shoutd probably not be attempted. in lieu of recompaction, the area to receive fill shou(d be blanketed with washed rock or quarry spalls to act as a capillary break between the new G[I and lf�e wet subgrade. Where the exposed ground remains soft and further overexcavation is imf�ractical, placement of an engineering stabilization fabric may be necessary to prevent contamination of the free-draining layer by sil[ migration fr��n br1u���. . Afier recor�ipaction of tfie exE>oscd ground is tested and apprc�ved, or a free-draining rock course is laid, structural fill may be placed to attain desired grades. Slructural fill is defined as non-organic soil, acceptable to the geotechnicat enbineer, placed in maximum 8-inch toose lifts with each lift being com�acted to 95 percent of �he rnodi�ed Proctor maxunum density using ASTM:D-1557 as the standard. [n the case of roadway and u[ility trencf� fitling, the hackfill should be placed and compacted in accordance with County codes and standards. "fhe t�p of the compacted fitl should extend horizontatly outward a minimum dista��ce uf 3 feet beyond the location of tf�e �erimctcr footings or roadway edge before sloping down at an angle of 2H:1V. The contractor shouid note that any pr�posed fill soils must be evaluated by AESI prior to their use in filts. This would reguire that we have a sample of the material 72 hours in advance to perform a Proctor test and determine its field compaction stanclard. Soils in which the amount of fine-grained material (stnaller than the No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) sllould be considered moisture-sensitive. Use of moisture-sensitive soi! in slructural fills should be timited to favorable dry weather conditions. The un-site soils typically contained 5 percent silt or more, and are considered ' moisture-sensi[ive wheiz excavated and uscd as fill materials. Construction equipment traversing the si[e witen the soils are wet cai� cause considerable disturbance. Augusr 24, 2005 ��ssocr��Fn r�nrx scir=,vchs. �rvc.

GeopiersT"' are formed by dritling to a pre-determined depth with an auger of a specified diameter. Crushed rock is then cocnpacted into the driEled holes in thiii lifts. The result is a cotwnn of compacted aggregate and compaction of soils surrounding the Geopiers'�"'. GeopiersT"' are designed by the contractor who instalis thern who determines Geopierr"' spacing, depth, and diameter to meet projec! goats. 1'he exploration logs attached with this report can provide a basis for the design. Conventional shallow foundations are then constructed above the subgrade after GeopiersT"' have been instalted. 8.2 Rammed Afi�re�ate PiersTn� We understai�d that a newer "Ramm�c� :\ggregate Pier'n'" tiystcrn h�s also been used successfully by Geopier Foundation Calipany. The end resuit of Rarnmed Aggregate Pier'�"' construction is similar to a Geopier'"', but instead of drilling an open hole, a hollow tnandrel is � advanced to allow rock placement and compaction. One advantage is that Ranuned Aggregate PierT"' constructior� docs not generate dril( cuttings that require disposal, and wet subsurface conditions that might be unfavorable for GeopierT"' construction are less of an issue since no open hole is used for Rammed Aggregatc PierT"' construction_ Wc have been briefed on this system and agree that Rammed Aggrcgate PiersT"' inay be a suitable system for this project. Ultimately, Geopier Founclation Company should selcct the appropriatc foundation system and provide the detailed design of the ground improveEnent system. 8.3 Rapid Impact C�mpaction Geopier Foundation Company has subgested the use of Rapid lmpact Compaction to densify the alluvial sediments prior to construction of conventionat foundations. The Rapid [mpact Compaction techniques appear similar to Deep Dynamic Compaction, which has been used for many years worldwide to eiensify loose surficial deposits. The Rapid Impact Compaclion equipme«t consists of a track-mounted excavator fitted with a hydraulic ram and tamping foot. The ram repeatedly strikes the ground surface compacting the Ioose surface seduneats_ The process is repeated until the entire building pad is compacted. We understand that the process can densify soils !0 to 15 feet deep, depending on soil and water conditions. The problematic alluvial deposits on this site would like(y be suitable for this applicatiort. Since the suggested equipment has been used infrequently in the Puget Sound area, we recommend that a con�irmatory exptoration program be completed along with the Rapid Impact Compaction. We would reeonunend that soif borings and SPT sampling be completed in compacted areas to confirm that the alluvial scdimeitts have beeu adequately densified.

Geopiers�"' can then be installed. When Geopier`"' installation is complete, the building pad can be cleared of drill cuttings and fine-graded with structural fill. If Rapid Impact Compaction is used, the impact craters would be filled with structural fill to achieve finish grades. Footings can then be constructed using standard shailow foundation design and construction methods. For �lanning purposes, we anticipa�e that shal(ow foundatious above Geopiers'"' or recompacted soits coutd be desigc�ed with an atlowable foundation soil bearing pressure of 3,000 pounds per square foot (pst). If desired, GeopiersT"' could also be used to support the building floor slab without the 2-foot-thick layer of structural fill recorrunended in lhe Site Preparation sectiof� of this report. 9.0 PLOOR SUPPORT Slab-on-grade f�oors are expected to support light loads, such as peo�le and f�irniture. The recorrunendations in this report are ap�ropriate for light loads such as those described. If vehicles, forktif�s, rnaterials storage, or other heavy loads are expec[ed, we shouId be allowed to offer situation-specifie recomrr�endations. Cast-in-piace concrete floor slabs may be used over strucWral fiil as recommended in the Site Yreparation section of this report, or above a syscem of Geopiers�"' (or Rammed Aggregate Piersr"') that are designecl by the GeopierT"' contractor or a subgrade that has been properly improved by Rapid linpact Compaction. 'The floor should be cast atop a minin�um of 4 inches of washed pea gravel to act as a capillary break. It should also be protected from dampi�ess by an impervious moisture barrier at least 10 mils thick or othei-wise sealed. 10.0 DRAINAGE CONSIDERATIONS All footing walls should be provided with a drain at the footing elevation. Drains sl�ould consist of rigid, perforated, polyvinyl chloride (PVC) pipe surrounded by washed pea gravel. The level of the perforations in ihe pipe should be set at the bottom of the footing at all locations and the drain collectors should be constructed with sufficient gradient to atlow gravity discharge away f'rom the building. In addition, all foundation walls taller than 3 feet should be lined with a minimum, 12-inch-thick, washed gravef blanket provided over the full height of the wall and which ties into the footing drain. Roof and surface runoff should not discharge into ihe footing drain system but should be handled by a separate, rigid, tightline Augusl 24, 2ppj ASSOClATF,D CARTH SClF.NCF_S, /NC.

In planning, exterior grades adjacent to foundations should be sloped downward away from the structure to achieve surface drainage. These recommendations app(y to conventional sliallow foundation wa{!s and landscape walls tess [han about 4 feet tal1. 11.0 CAST'-IN-PLACE RETAINING WALLS Alt backfil! behind foundation walts or around foundation units should be placed as per our recommendations for struetural fill and as described in this section of the report. Ho�•izontally backfilled walls, which are free to yield laterally at least 0.1 percent of their height, may be designed to resist an active lateral earth pressure represented by an equivalent fluid of 35 pounds per cubic foot (pc�. Fully restrained, horizonta(ly backfilled, rigid walls which cannot yield should be designed for an at-rest pressure of SS pcf. Watls with s1oE�ing backfil! are not expected, but should be designed with appropriate slope surcharge ��ressu,-es. We should be allowed to provide specific slope surcharge pressures if walls with sloping backfill are ❑sed. If parking areas are adjaccnt to walis, a surcharge equivatent to 2 fcet of suil shou(d be added to the wall height in determining lateral design forces. Ttfe Iaterai pressures presented above are based on tlze conditions of a unifonn backt►ll consistin�; of native soils or imported structural fill compacted to 90 percent of AS1'M:D-1557. A higher degree of compaction is not recommended as this will increase the pressure acting on the waEls. A lower compaction may result in seEtlement of the slab-on-grade or other structures supported above the walls. Thus, the compaction teve[ is critical and must be tested by our firm during placement. Surcharges from adjacent footil�gs, heavy construction equipment, or sioping ground must be added to the above values. Perimeter footing drains should be provided for all retaining walls as discussed under the section on Drainage Considerations. It is impei-ative that proper drainage be provided so [hat hydrostatic pressures do not devetop against the walls. For walls less than 3 feet tall, the foundation drain, as recommended in the Drainage Considerations section of this report, is expected to be adcyuate. For watls more than 3 feet tall, a blanket drain is required. This would involve installation af a cninimum, 1-foot-wide blanket drain for the full wal! height using imported, washed grave! against the walls. The draiczage blanket shoutd be continuous with a�id freely eommunicate with �he fou�idation drain. Foundation wall foo[ings/keyways surrounded with structural fill or alluvium n�ay be designed for passi<<e resistance against lateral translation using an equivalen[ fluid equal to 200 pcf. The passive equivalent fluid pressure diagram begins at the top of the footing; l�owever, total lateral resistance should be summed only over the depth of the actual key (truncated triangular diagram). Passive resistance values include a factor of safety equa( to 3 in order to reduce ihe amount of movemcnt necessary to generate passive resistance.

This is a►� allowable vaiue and includes a safety factor. Tl�e soil under the footings must be recompacted to 95 percent of the above-mentioned standard, as recommended in the Site Preparation section of this report, for this value to appIy. 12.0 PAVEMENT RCCOMMENDAI'IONS The parking lot pavement for this project is expected to be supported by structural fill. Pavement for this project is expected to include areas that will be used primarily for car driving and parking. Some areas will also be subjected to heavy traffic, such as garbage [rucks and delivery trucks_ We reeommend that passenger car driveway and parking areas consist of 2.5 inct�es vf hot mix asphalt, Class '/z inch (HMA 'h inch) (equivalent to Class B asphalt concrete paving �nCPJ) above 4 inches of cruslied surfacing base couise (CSBC) (WSDOT S�andard Specification 9-039[3]). Pavement Cor tructc areas should consist of a minimum section of 4 inci�es of HMA '/a inch over G inches of CSBC. All dep[hs given are compacted depths. All paving �na[erials, base course materials, and �lacement procedures sl�ould comply with suitabte standard specifications, such as the Washin,�ton State Depunment of I ransportation Standard SpeciftcaFions for Road, Bridge, and Municipa! Construction, ar other suitable specifications. All structural fill and all native subgrades less than 4 feet below finished gradc for a planned paving area should be compacted to 9S percent of the modified P��oc�or rnaximum dry density as determined by ASTM:D-15S7. Prior eo structural fill placement or to placemen[ of base course materials over native subgrades, the area should be proof-rolled under the observation of AESI with a loaded dump truck or other suitable equipment to identify any soft or yielding areas. Any soft or yielding areas should be repaired prior [o continuing work. (f desired, asphalt treated base (ATII) can be substituted for most of the CSBC and used to provide a construc[ioa-working surlace. Atter the buried utiiities are in place, the subgrade is �repared, a 2-inch-thick leveling course of CSBC is placed, and the ATf3 is laid and compacted. This ATB surface is then used for construction access, and once most of the heavy construction traffic has subsided, any damaged pavement areas are repaired prior to final surfacing with ACY. For this project, 4 inches of CSBC under passenger car areas can be replaced with at least 2 inches of ATB with a 2-inch CSBC leveling course. Six inches of CSBC under heavy traffic areas can be replaced with 3 inches of ATE3 over 2 inches of CSBC. Surface-wearing layers of I�MA '/z inch should be used above the ATB, as described above_ This is an optional substitution that can be used if paved construction staging is desired, but is not required for structural purposcs.

We are availab(e to provide additional geotechnical consultation as the project design develops and possibly changes from that upon which this report is hased. We recommend that AES[ perform a geotechnical review of the plans prior to final design comptetion. In this way, our earthwork and foundation recommendations may be properiy interpreted and implemented in the design. We are afso available to provide geotechnical engineering and monitoring services during construction. "fhe integrity of the foundations for buildings and of new pavement depends on proper site preparation and construction procedures. In addition, engineering decisions may have to be made in the field in the event that variations in subsurface conditions become apparent. Construction monitoring services are not par[ of the current scupe c�f work If these services are desired, please let us know and we will prepare a cost proposal.
