Ady 7, 1997 1 USWEST Wireless PCs-Red Sewerage Agency Location • Minor Modification Request i1. INTRODUCTION USWEST Communications is in the process of developing a new w;rcless telephone system called Personal Communication Services, or PCS. PCS is a unique combiration of telecommunication services that will provide the public with the next generation of wireless devices, such as: compact cellular telephones with paging and voice-mail service, wireless fax machines and fax modems, and ate array of other customized mobile equipment. When fully developed, PCS will allow for an all-in-one telecommunications device combining multiple services in a single wireless telephone. PCS uses new digital technology to produce a higher quality transfer of voices and data versus the older analog/digital systems that are currently being used by many existing wireless telephone service providers. This digital technology also accommodates the transfer of data and graphics. In addition, PCS operates at a higher frequency, around 1,900 megahertz, and broader firrA uency band than conventional cellular. This allows for more simultaneous caNers. in order to provide these services, t1SWEST is developing a PCS network in Portland. PCS works by splitting a region into smaller geographic areas called cells, each cell is served by a transmitter and receiver or base station. As a caller moves across the landscape, the call is passed or "handed-oft" from one base station to another. Each base station is connected to a mobile telephone switching office, which is linked to the land based phone network serving your home or office, individual base station site locations, such as the proposed site, are selected based on a number of considerations related to topography, distance frorn other base stations, proximity to traffic cortidws, and other technical features. USWEST engineers utilize computer modeling and radio testing to determine potential sites. Because PCS base stations consist of very low powered transmitters, which cover a relatively zmall geographic arca, there is limited flexibility in site selection. This proposed PCS bast: station facility locuted at the United Sewerage Agency site is designed to provide PCS service to portions of Tigard and Washington County. Wlten developed, this facility will connect to other neighboring facilities in the network allowing for uninterrupted PCS service in this region of Washington County. USWEST is committed to providing quality PCS service to Tigard and the Portland Metropolitan arca for years to -omc. watt Pacific, Inc.

PROJECT DESCRIPTION The project consists of the installation and operation of antennas and associated equipment cabinets for USWEST Wireless Personal Communications Service Network. A total of six (6) antennas (plus 3 expansicn) and two (2) equipment cabinets (plus 2 expansion) are proposed at this sille. Each antenna is four feet wide by four feet (4'x4') deep by three fbet - six inches (3'6") tall. The self-contained equipment cabinets are two feet - six inches (TV) wide by two feet - six inches (TV) deep by five feet (5') tall. The system will both transmit and receive radio signals for a regional USWEST network. The antennas will be mounted to the existing building parapet. The equipment cabinets will be mounted to a steel support frame which will be attached to the roof structure of the existing building. No new support structures will be constructed. The existing structure is United Seweruge Agency's chemical feed building located at 16375 SW 85th Avenue. The site. is zoned IP(industrial Park) .

CWC-HDR 0-4472 May 19, 1988 Page 2 2.0 I TRODUCTION This report presents 'he results of our subsurface exploration and geutechnlcal engineering study for the ' proposed Durham Advanced Waste Water Treatment Plant (AWWTP). The proposed development and locations of the subsurface explorations are presented on the attached Site Plan, Plate 1. The purpose of our study was to establish general subsurface conditions at the site on which to base our conclusions and recommendations for foundation d"gn and construction considerations. The scope of work consisted of literature and past report research, field explorations, and geotechnical engineering analysis. This study has been completed in general accordance with our contract of April 13, 1988. This report has been prepared for the exclusive use of CWC-HDR Engineers, their client and their agents, for specific application to this project, In accordance with generally accepted geotechnical engineering practices. 3,0 PROJECT QX=1P_L4n The project site Is located south of Durham Road at S.W. 85th Ave. in Durham, Oregon. The project will Involve a new Headworks facility about 120 feet x 120 feet In plan dimension, a series of new utility lines, upgrading and altering existing clarifies and aeratlon basins, and two new pumps at the Raw Sewqge Pumping Station. The now Headworks facility will have lower floor elevations of 10 to 15 feet below existing grades, and some of the utility Imes will be up to 20 feet deep. Items of concern are allowable bearing capacity, ' retaining structures, drainage, excavition, and control of water during construction. 4.9 .UBF9-Qf �jt7NQ1TJM U) 41_Ea1QmfiQa TGh-gRU0 ' Our subsurface exploration consisted of drilling 15 borings of 21.5 to 41.5 feet in depth, with a traller- mounted Versa Drill. All explorations were observed by a geologist from our firm who logged conditions ' encountered and obtalnaf samples for laboratory testing Exploration logs, together with more detailed descriptions of the drilling and sampling techniques, can be found in the Appendix 4, it QQnS�)tlOfa 4.1j_SUf Kq -The locations of the rew facilities are mostly within the confines of the existing AWWTP and ' as such, will probably be founded (-n compacted fills, consisting of reworked natNe soils. The Headworks ' CWC-HDR 0-4477 May 19, 1988 Page 3 facility Is located at the highest part of the site, west of S.W. 185th Ave., In a relatively und!sturbed area of pastes a grass and small trees. The site slopes gently downward toward the southeast, from a high of approximate EI. 180 to El. 125. ' 4.2.2 Subsurface -As nu,ed previously, the bulk of the existing site facilities are underlain by about five to 15 feet of sandy slit fill, presumably emplaced during original construction. The fills appeared to consist of relatively well-compacted (stiff to very stiff), reworkeo native soil. Although h may exist, we observed no residual topsoil below the fill. The term' ler of our explorations revealed six to 12 Inches of v.psoll In the ' area of the existing facility, and possibly two feet thick In the pasturo/orchard where the new Headworks Is to be located. tThe native soils consist of typical floodplain deposits of loose to medium dense, Interbedded slit and silty fine sand with scattered lenses of gravel. The sands arty typically more silty near the ground surface (or just below the fill) and grade cleaner with depth. Any resulting settlements should be rapid and uniform. eAa3 Groundwstgr - We only encountered free groundwater in 8.10, at 18.5 feet below existing grade. However, most of the borings had perched water In the sand layers which could translate Into a seasonal groundwater level. Piezometers were installed In B-14 and B-15, and one was scheduled for B-5 During drilling, B-5 was a "dry hole", so we left it open and returned several days later to see whether the perched lenses would fill it up. The nose was still dry, so we backfilled It without a ple7ometer. Cgnversely, the piezometer in B-15 had filled to within two and one-half feet of the ground surface during the same amount of time. It Is possible that existing underground utility trenches have"dried up" portions of the site. Considering t;ie time of year, we expert that during extremely wet winters the groundwater may rise to ' within a few feet of existing grade, and during the driest months it may drop below 20 feet. Excavation and rn construction within the ground\vatar zone are discussed later In this report. 1 "ISIGN REC9�uiMF�lQATIONS ite Preoar-jtlon We have provided ►ecommendatIons for both wet weather and dry weather construction. Because the ' near surface soils consist of moisture-sensitive slits, If possible, It Is recommended that the site ba prepared during relatively dry weather. 1 1 CWC-HDR 0-4472 May 19, 191313 Page 4 5.1.1 Sias SlrioQlnn - Prior to beginning construction, all areas of the site that will recelvo wilding or pavement elaments should be stripped of topsoil, roots, and any non-engineered surface fill. Minimum %tripping depths may range from six Inches in areas of existing facilities,to two and one-half to three feet In order to remove any non-engineered fills (If any) anti; :fie thick topsoil in the northwest comer of the site. Existing fills, as discussed in Section 4.2.2, consist of generally good quality material, but may contain occasional debris, and do not appear to be underlain by topsoil. After stripping, we recommend that the resulting exposed surface be observed by a representative from our office, and any areas of soft soli or remaining fill should be overexcavated. 1 2 ry W• then Coq}tructlon - Seasonal wetting, drying,freezing, and thawing can substantially loosen the near-surface soils. After stripping and excavating to final grades, but b(i,are any new fill is Installed, we recommend that all building, pavement and fill areas be scarified to a depth of at least eight Inches. The scarifled soll should be aerated as necessary and then compacted to at least 92% (95%below pa:,amer.ts) trelative compaction (AASHTO T-1130) We recommend that we be retained to obser.,e this operation. Even during dry weather it 1r possible that some areas of the subgrade will hecomo soft or will pump, particularly In cut areas. Soft or wet areas that rannnt be effectively dried and compactiod should be prepared In accordance with Section 5.1.3, Wet Weather Construction. .1,3 Wit Wetther (, tMrjlgn - Curing wet weather, when adequate moisture c' 1trol cannot be obtained, or in areas softened by prolonged standing water, a granular working blanket may be Installed to support construction equipment and pro-'de a firm base on which to place subsequent fills, floor slabs and pavements. Commonly the working blanket consists of a bank run gravel or pit run quarry rock (six Inch to eight Inch maximum size with no more than 5% by weight passing a No. 200 sieve). We recommend that we be consulted to approve the material befurp Installation. The working blanket should be Installed on a stripped subgrade In a single lift with trucks end-dumping off ' an advancing pad of granular fill. It should be possible to strip the site with the careful opwation of crawler- mounted equipment However, during prolonged wet weather, operation of this type of equipment may cause excessive subgrade disturbance and final stripping may have to be accomplished with a large backhoe or similar equipment, working,rom the advancing pad of fill. After Installation, the working blanket ' should he compacted by a minimum of four complete passes with a moderately heavy steel drum or grid roller. 1 CWC-HDR 0-4472 May 19, 1988 Page 5 The working blanket must provide a firm base for subsequent fill Installation and compaction. It has been our experience that 12 to 18 Inches of working pad Is normally required, depending on the gradation and angularity of the working pad material. This assumes that the material Is placed on a relatively undisturbed subgrade In accordance with the preceding recommendations, and that it Is not subjected to frequent heavy construction traffic. A very conscientious contractor r^3y be able to prepare the site vrith track- mounted .julpment without resulting In major subgrade disturbance. However, since It will not be possible to scarify and compact the surface during wet weather, we recommend a minimum 12 Inch granular working pad be Installed in all areas where ;carificatlon and compaction is not accomplished, If settlement or cracking is a concern (including floor slab areas). 5.2 Proof-ro&A Following subgrade preparation and prior to fill placement or bass course Installation, we recommend that the subgradA be proof-rolled with Q fully-loaded 10 to 12 yard clump truck. This pertains to all pavement and fill areas. Any areas that putnp, weave or appear soft and muddy should be scartfled and dried or overexcavated z7d backfilled with compacted granular fill. If a significant length of tlm41 gasses between ' completion of fill placement and commencement of construction operations, or If significant traffic has been routed across the site, we recommend that the site be similarly proof-rolled again before final ' placement of base rock or asphalt. ' Ig•� FII • Any fills on this project should be Installed on a subgrade that has been prepared In accordance with the recommendations in the previous sections of this report. Fills should be installed In horizontal lifts not ' exceeding about eight inches In thickness, and should be compacted to at least 92% relative compaction (AASHTO T-180) for native soils, and 95% relative compaction for Imported granular materials and the upper eight Inches of pavement subgrade, regardless Gf the type of fill material. Compaction criteria may he reduced to 85% in landscaping or planter areas. ' During dry weather, structural fills may consist of virtually any relatively well-graded soil that Is free of debris and organic matter and that can be compacted to the preceding specifications. The nonorganic existing fills encountered at this site (excluding topsoil) would generally be adequate for reuse as ' compacted fill. If wood, debris or topsoil are encountered they should be removed prior to filling. Native silty sands and sands would also make Adequate dry weather fill ' CWC-HDR 0-4472 May 19, 1988 Page 6 In order to achieve adequnte compaction during wet weather, we worimend that fNis consist of well- graded granular soils (sand or sand and gravel) that do not contain mon than 5% material by weight passing the No. 200 sieve. In addition, it Ie usually desirable to limit this material to a maximum six to eight Inches In diameter for future ease In the InsLeilatlon of utliltles. 5.4 Areai Settleininv The native soils at this site (outside existing engineered fill areas)are somewhat loose and exhibit moderate compressibility. Areal fills could increase the stresses In the oxisting soil strata, and could cause variable consolidation. We understand t"►at no significant new fills are proposed. FNIs up to three or four feet should not result In significant settlements M the she surface Is prepared as oudloed In pre-dous sections of this report. If fills thicker than four feet are proposed (above existing grades), we should be contacted for additional recomrnendatlons. ,Q Foun�!a�jg� This section pertains mainly to tho new Heady orks building area. We are assuming that this building will ' have only I!ght loads associated with a two-story building containing a basement. Column loads are assumed to be under 80 kips, with wall loads not exceeding four kips per lineal foot. Subject to site preparation as outlined In Sertion 5.I, these footings will bear on native solla, or possibly one to two feet of engineered fill. For this case we recommend that these foundations be designed for a maximum bearing pressure of 2500 psf and that they be a minimum of 12 Inches wide and 18 Inches below finished grade. This pressure applies to dead plus frequer,, ,eve load and may be increased by one-third for wind or seismic loading conditions. For foundations established In accordance with the above recommendations we estimate that settlements will not exceed one-half Inch. If the building loads are substantially higher than those nwpd, wr should fie contar':vi for additional recommendations. °s §A Relaining Wallp ' This portion of the report pertains mainly to the new Headworks building that appears to be substantially below adjacent exterior grades. Normally such structures are either built as a s1ructura117 reinforced box ' designed to resist hydrostatic loads, or have a drainage system that allows dewatering during periods of high groundwater. This being the case, we would recommend that the walls be designed for the pressures ' shown below' 1 Slope to Drain Topsoil or 1% avemont °a 12 In.. Min. b {.-- 16 ft..

Since overcornpactlon of this fill can greatly Increase lateral soil pressures, we recommend that it be compacted between 88% and 90% relative compaction (AASHTO T-180 or AS I M D- 1557). In addition, we recommend that all fill within Me feet of walls (measured horizontally), be ' compacted with lightweight, hand-operated equipment. If any foundations or mayor loads will be supported on wail backfill, wo shOUld be contacted for additional recommer-datlons. ' t5,7 Subtsur_f r�.e Q,r,�ltllSt! ' Although groundwater levels were encountered at about 18.5 feet In 8-10 at the time of our exploration, they rose during a fairly short period of time to two and one-hair feet in boring 8-15. In addition, a perched water surface develops within the upper slity sands. Because of the relatively high lateral permeability of pnative soils, extensive drainage systems would be required to lower the groundwater table. We recommend that any areas below exterior grade that cannot be drained by gravity be designed to resist ' hydrostatic pressures If specific areas appear to fit this case, we wot,ld be happy to address drainage with you on a case-by case basis. Normal gravity wall drains and subdrains should consist of a four inch diameter perforated pipe enveloped In drain rock, with the rock wrapped In a nonwoven filter fabric. An acceptable filter fabric Is Flbertex 150, or equivalent A typical detail for wall and under-slab drains Is attached as Figure 5.8. The proposed floor slab in the Headworks building may be subject to heavy Poor loads, and may well be trafficked by forklift trucks. We would be happy to assist In the de sign of an appropriate Poor slab section 1 CWC-HDR 0-4472 ' May 19, 1988 Page 8 M provided with loading details. As a minimum we recommend that floor slab areas be compacted In accordance with Section 5.1.3. In addition, we recommend Installing a minimum of six Inches of ' compacted (95%, AASHTO T-190) crushed rock below floor slab areas. If heavy floor loads are anticipated, 12 Inches of crushed rock may be necessary. To minimize potential offsets at joints, it Is Jusually desirable that all joints be either xeyed or doweled.. ;n addition, If flours are not drained In accordance with Section 5.7, they may be subject to hydrostatic up - n forces. If this type of design Is contemplated,we should be contacted for additional recommendatlors. 5.9 Temorarx SiotsiMOs[tiffilf All temporary excavations should be adequately sloped or shored. Because of the variable so# moisture conditions, It Is not possible to provide recommended 'safe' slopes, end final decisions may have to be based on fielJ conditions at the time of construction. We expect that slopes of 11-1:1V should remain stable ' to depths of at least 15 feet, providing groundwater Is not encountered All of our explorations were advancad with a light weight drill rig. No significant obstructions were encountered in any of our explorations (depths up to 41.5 feet). Some sidewall caving do occur near the groundwater table and in some perched water zones. 6.0 PAVEMENT DEIGN In order to facilitate pavement design, we have reviewed a number of COR tests that we have performed In the vicinity of the site and performed two additional CBR tests for this project. Based on this data we ' recommend designing for the following: 0. ' Relative ��'n�actlon � B-4.110 kValue U) ' 95% 5 28 140 We have alternate pavement designs for both asphalt and portland cement concrete. Asphaltic concrete designs have been prepared In substantial accordance with State of Oregon design methods. The State of Oregon does not have design standards for conventional Portland cement concrete pavements These pavements 'lave been designed In accordance with methods developed by the Portland Cement ' Association (PCA). 1 CWC-HDR 0.4472 ' May 19, 1:488 JAILE 8.0 PAVEMENT DESIGN ASPHALT CONCRETE PAVEMENT: Approx.

Lesser thicknesses may be appropriate for automobile and truck parking areas where occaskxuu maintenance Is acceptahle. 1 1 1 1 CWC-HDR 0-4472 May 19, 1988 Page 9 Because we do not know the projected traffic flows for this she, we have provided a range of pavement designs for various traffic conditions. Design pavement sections are provided In Table 6.0, Pavement Designs. Our designs assume that the subgrade will be prepared In accordance with Sections 5.1,5.2, and 5.3. The top eight Inches of subgrade should be compacted to 95% relative compaction. Specifications for pavements, base course and subbase shou;d conform to Oregon State Highway specifications Section 703. Lime-treatment is not recommended for this shu due to the high organic content at depth. ' If possible, construction traffic should be limited to unpaved and untreated roadways, or er icially constructed haul roads. If this Is not possible, the pavement design selected from Table 6.0 should include an allowance for construction traffic. The recommendations contained In this report are teased on information gathered during our field and laboratory study• and on design Information provkiec by CWC-HDR. We have not yet received a final copy of the plans for this project. We recommend t!iat we be provided an opportunity to review the final plans and specifications when they become available. This will allow us to determine whether any change In concept may have affected the validity of cur recommendations, and whether our recommendations have been correctly Interpreted. In order to correiatt, preliminary soil data with the actual soil conditions encountered during construction ' and to (;heck for construction conformance to our report, we also recommend that we be retained for construction observation of stripping, grading, compaction, founda!ljn excavations and other soils related ' portions of this project. 4 ' Respectfully submitted, W RITTENHOUSE-ZEMAN & ASq=TtS..J�6� 48Lf C" R t— t -----t_ _ _ 0�1 / Richard W.
