We understand that the 0.29- acre parcel will be developed for a residential building. The steepest slope measured on the property (Northwest of the proposed building) is approximately 29 percent. No slopes on the property or nearby parcels reach 40%. Hence, Mason County requires a geological assessment. SITE CONDITIONS The project site is located approximately 5.75 miles north east of Shelton, Washington. The parcel is located in an area of moderate residential development; see the Vicinity Map (Figure 1) following this report. The site is accessible from E Sleaford Road. The site elevation ranges from approximately 240 to 250 feet. The lot is mostly vegetated with scrub brush but includes sword ferns, bracken ferns, ivy, Oregon grape, as well as maple, alder, and fir tred* Surface water was not observed onsite although the building site is situated near a seasonal shallow drainage. No evidence of ponding was observed. No slope instability was observed at or around the proposed building location. Onsite and surrounding trees are straight and vertical. �r° h RINI% i ®► Mason County G.I.S Terraserver 1001 1 Blomberg Street SW,Olympia, WA 98512 5 Phone#: (360) 754-4612 Fax#: (360) 754-4848 GEOTECHNICAL TESTING LABORATORY GEOLOGIC CONDITIONS The Soil Survey of Mason County, USDA Soil Conservation Service (1960) has mapped the site soils as Alderwood gravelly sandy loam, 5 to 15 percent slopes(Ab)and 15 to 30 percent slopes(Ac). The survey reads, Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab): - the Alderwood soils typically formed from mixed gravelly glacial till dominated by acid igneous rock. It occupies undulaog to rolling moraines. In undisturbed areas, a 1- to 2-inch mat of very dark brown, acid organic matter is on the surface. This grades to a thin, dark grayish- brown, highly organic mineral soil. The surface soil consists of a friable, brown, medium acid gravelly sandy loam 8 to 13 inches deep. It has a weak granular .structure and contains numerous rounded shot. Below the surface soil, to depths ranging from 18 to 24 inches, is a pale-brown gravelly sandy loam that is very friable, is single grained, and contains small to moderate amounts of shot. Between this layer and the cemented till is a 3- to 10-inch layer of very pale brown gravelly sandy loam. It contains no shot and is firmer but has the same texture as the layer above... The Geological Map of Shelton Quadrangle, Washington by Logan et al,(2003)describes the site geology as Till, (Qgt). The report reads: Till, late Wisconsinan (Pleistocene)—Unsorted, unstratified, highly compacted mixture of clay, silt, sand, gravel, and boulders deposited by glacial ice of the Puget lobe; gray; may contain interbedded stratified sand, silt, and gravel; sand-size fraction is very angular and contains abundapolycrystalline quartz, which distinguishes this unit from alpine till; cobbles and bofffflers are commonly striated and (or) faceted; although unweathered almost everywhere, may contain cobbles or small boulders of deeply weathered granitic rock. Our observations of the site conclude that the location is situated on shallow Alderwood soil overlying Vashon Till (Qgt)as noted above. GROUNDWATER CONDITIONS Groundwater seepage was not observed throughout the site. The nearest reported well logs were reviewed and are provided at the end of this report. Based upon the reported well logs, we estimate the depth of the water to be approximately 65 feet below ground surface. Wetland features were not observed at the proposed building location or throughout the site. The closest wetland is approximately 0.12 miles southeast of the property. The closest waterbodies in the area; are Cranberry Creek approximately 0.26 miles west of the property and Limerick Lake approximately 0.32 miles west of the property. No significant impact is 4ected from these waterbodies and wetlands. DEPTH TO COMPETENT SOIL • The competent material was observed at approximately 0 to 12 inches below the existing ground surface. 10011 Blomberg Street SW, Olympia, WA 98512 6 Phone#: (360) 754-4612 Fax#: (360) 754-4848 GEOTECHNICAL TESTING LABORATORY PAST SLOPE INSTABILITY Surrounding the subject site, trees were observed to be straight and vertical. No indication of past instability was discerned at the proposebbuilding location. No active slumping and sliding was observed either on the subject site or on the adjoining property. Coastal Zone Atlas has mapped the site as stable. HISTORY OF LANDSLIDE ACTIVITY Slumping and sliding was not observed at the site. No landslide activities observed during the site reconnaissance or through the inspection of available geological maps. POTENTIAL FOR LANDSLIDE ACTIVITY No seeps and springs were observed on site and the slopes are moderate on site, Even though the steepest nearby slope is approximately 29 percent, the potential for landslide activity is very slight on the site. The onsite and offsite slopes are not a concern for potential landslide activity. The surrounding area includes moderate slopes that are well vegetated. The Liquefaction Susceplip7bility Map of Mason County, Washington by Palmer, Magsino, Poelstra, Bilderback, Folger,and Niggemann (September 2004)maps the site area as having a very low liquefaction potential. The Site Class Map of Mason County, Washington by Palmer, Magsino, Bilderback, Poelstra, Folger, and Niggemann (September 2004) maps the site area as site class B to C. Site class B to C represents dense to stiff soil and a soft rock condition. CONCLUSIONS AND RECOMMENDATIONS GENERAL Based on the.results of our site reconnaissance, subsurface observations, and our experience in the area, it is our opinion that the site is suitable for the proposed project. The proposed structures will not undermine adjacent slopes. Proposed activities and site conditions for the development do not warrant a more comprehensive Geotechnical Report. We recommend no further action is needed unless areas of concern are unearthed during construction or damage ensues from removing vegetation. To minimize erosion and sedimentation,we recommend that vegetation remain dPbe cultivated in areas outside the building location. The planned fill in part of the drainage to permit access should not affect the building location. The details must be addressed by the grading permit. If there are any changes in the loads, grades, locations, configurations or types of facilities to be constructed, we should be given the opportunity to review our recommendations and provide written modifications or verifications, as appropriate. Changes to the Mason County Code require our firm to revisit the subject site prior to development, if six months has elapsed,to ensure the conditions are in agreement with our original report. Any potential hazards can be overcome in such a manner as to prevent harm to property and public health and safety, and the project will cause no significant environmental impact for the life of the project. 10011 Blomberg Street SW, Olympia, WA 98512 7 Phone#: (360) 754-4612 Fax#: (360) 754-4848 tfa GEOTECHNICAL TESTING LABORATORY If tested and confirmed, the onsite soils may be suitable for use as structural fill material. Saturated soil conditions may be associated with these soils during or following extended periods of rainfall. However, to reduce grading time and construction costs, we recommend that earthwork be undertaken during favorable weather conditions. RECOMMENDATIONS FOR STRUCTURAL FILL All fill material should be placed as structural fill. The structural fill should be placed in horizontal lifts of appropriate thickness to allow adequate and uniform compaction of each lift. Fill should be compacted to at least 95 percent of MDD(maximum dry density as determined in accordance with ASTM D-1557)to grade. The appropriate lift thickness will depend on the fill characteristics and compaction equipment used. We recommend that the appropriate lift thickness be evaluated by our field representative during construction. The suitability of materiafor use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (Material passing No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. During wet weather, we recommend the use of well-graded sand and gravel with less than 9 percent(by weight) passing the No. 200 sieve based on that fraction passing the 3/4-inch sieve. If prolonged dry weather prevails during the earthwork and foundation installation phase of construction, a somewhat higher(up to 10 percent)fines content will be acceptable. Material placed for structural fill should be free of debris, organic matter, trash, and cobbles greater than 6 inches in diameter. The moisture content of the fill material should be adjusted as necessary for proper compaction. REPORT LIMITATIONS AND GUIDELINES FOR USE We have prepared this report for the exclusive use of Gary Gribble and his authorized agents for the proposed residential buildings in Mason County, Washington. Site inspections, research, and mapping have culminated in this report. This report is intended to meet the requirements of the Mason County Critical Areas Ordinance. This report does not specifyvetbacks for: line-of-sight setbacks, FWHCA setbacks, eagle tree setbacks, wetland setbacks, or property line setbacks. Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in the field of geotechnical engineering in this area at the time this report was prepared. No warranty or other conditions, expressed or implied, should be understood. CONTRACTORS ARE RESPONSIBLE FOR SITE SAFETY ON THEIR OWN CONSTRUCTION PROJECTS Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to onsite personnel and to adjacent properties. READ THESE PROVISIONS CLOSELY Some clients, design professionals, and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. 10011 Blomberg Street SW,Olympia, WA 98512 8 Phone#: (360) 754-4612 Fax#: (360) 754-4848 GEOTECHNICAL TESTING LABORATORY Geotechnical Testing Laboratory, Inc includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with Geotechnical Testing Laboratory, Inc if you are unclear how these "Report Limitations and Guidelines for Use"apply to your project or site. • GEOTECHNICAL,GEOLOGIC,AND ENVIRONMENTAL REPORTS SHOULD NOT BE INTERCHANGED The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, geotechnical engineering or geologic reporting does not usually relate any environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports argot used to address geotechnical or geologic concerns,regarding a specific project. 40 i 10011 Blomberg Street SW, Olympia, WA 98512 9 Phone#: (360) 754-4612 Fax#: (360)754-4848 G EOTECHNICAL TESTING LABORATORY WELL LOGS WATER WELL REPORT Nouce of Intent No W162450 :Ongum&1st copy-Ecology,Tod copy-owner,3rd copy-dnMer A�EjLt 7 Unique Ecology Wed ID Tag No (a w Gargle) Q les conanicii0a Wa Right Parent No tin �siun MOINALCON.i'lfitU070N Notice IELof Jruatu h'ttrnittr tthew Welander Property Owner Natri� Ma wROPUSP.D U6)S Doaieaoc Iddtutrtai Mumotpd weU Street Adtlress0EE Lake Lmnerick Road [3t*Water ❑trngtaraa OTostWell ©over Shelton - - Prr or WORx t7weers tiumtr.r of weYl print Than brief %try C�1 Couuy Mason ry LoeanonS 11a•1/4 SE 11a Seca Twn.� RLfi�G"ele (fl ®New weu ❑Rtedddiooded areihod 0 Dug 0 aloted 0 Driven Or tau Z 0 bletWired ❑Oatble Rotary l]la- I p I�t Deg ' WWM DIMUNSMNS Diamner of wolt_�aau,dnlitd 1 G'I ft (a t,r still 17 318 C � Depth of tornpleted we p--.-��L__.__.fi kNot amb) Long Dog t C.crng Mtd5cc r~C1[VSitittlC?IOND@1MS Tax Patrol No 1 3-11-pWai) a� AAiag (N WeDded 6_ Diem from� +1 fl.fa,_UDR CONSTRt,+C7lON OR DP.COMririsSION PROCEDURE R mtalled Dialn from ft to�__-...__ft Pomtntion Devenbe by wrm,chacacw size of n awuS and structure and the 15 ❑Liner insulted fond and nature of the tr znal to each stntam penetrated,with at Icasi out i -_ Threaded bum kom h.to R atry for each change of informauoa ladreate all wafer eacouatered w PerioraGoas Yes {No USB ADDITIONAL SHINS IF NECESSARY) Type or Worawr tiled _ MATERIAL FROM TO tL sae of pedal ia_by—in and na of oafs_ __.from -..ft to�.ft +- S"Vcm Ej Yes ❑Nd ®K-Pat Lueatton _l 31 t aild1 - -ufacnuer's Nwnr Jnhnson BYOwn me Ium to coarse Type S low Modet No --- — ---_� -a Deast� Stae.._ _ _ fram 136 ft to 141 h sravel wsilt binder 6-1 M Dtarn slot site __from_-_ ft to ft Brown MedlLlm to coarse sand 6 a CravWfdttr packed ❑Yea [2No ❑Sireofgraveltsmd gravel-moist 84 Matrnatt P laced from .. _ R io... ri rOWn medlull to coarsea S Sarraee seal Ely.. ❑No To what depth^ 20 ft Somegravel-wet 107 Y Materials used in stal Benton't tc Brown coarse sand some 107 Did my tviia contsia unutable water, ]yes ravel-wet Type nrwaar _ __Dcprbotsaam Brown medium to coarse sand135 M Metbod of Sc Liig Suata oft rave 8n 'water 1 L y PUMP Manufacturers Ne+nc_ tQ - Type H P WATER LE " Land surface elevabon above mean sea revel _ __n O Stanc lewd II ft below top of well Dare R-1 Fi-()2 Z Aitesua prassure_.Jbs per sgaare wch Date N Artesian water is controlled fry al (Cip valve,etc) 'gyp WELL TESTS Dnwdown is amount water level is lowered below static level Was a pump test made"0 Yes M No If yes,by whom" ZSl Yield gaillmrn with ft drawdown after-his 0 Yield___gal gal loon with re drawdown after lin ((„yi Yield gdjmn wtdt ft drawdown after bnLU ' Reedwy dam(runt taken w zero when pump yarned o,R ware,Ierel nera and from; y wrll lop to are,loved Time Water Level Time Water level Teme Water Level N WaNbinink)n Stale c ham ofrKt Baiter sea gallmra with ft drawrdownalter hrs �irtnwnt nI 2 Aut est__20--tallrnw VAM stem set at a124 ft for I ks Ariesim flow it p In Due is I Temperature of water 4 was a chaaacal anaysu trades 0 Yes ER No FSm—ate 8-16-02 Compleled Date.-26-022 WELL CONSTRUCTION CERTIFICATION I constructed midRx accept responsibtLty for conswcaon of,has well,and its corMbance with all Wastungton well consmic-uon standards Mate rtals used and the information reported above are it=to my best knowledge and belief Xj Dnmer ❑1=aginoer❑Trattet Nam(Prmtl Drilling Company DrtUedEnginaedCrainte Sigtnattur. 2 5 Addross 170 SE Walker Park goad Driller or Trainee License No 07 city.S­zip Shelton WA 98584 Ntrainee,beenseid dn9cr's Cons ARC.ADDI098n S�naAire said Ltcenss too Pevwwon No Dafe-�- Eeotoby is m Bgaal oppormaity EmpkWcr ECY W0 I-TO(Rtv'Hill) 10011 Blomberg Street SW,Olympia, WA 98512 10 Phone#: (360) 754-4612 Fax#: (360) 754-4848 O GT�TECHNICAL TESTING LABORATORY VICINITY MAP �; � - a is•'���-- J____ � ���- —�- +�'� _ E `/ - _ `�)� '#St,Y *, f.. �� .`- ...cam.,_- ' ,� �+•� =.--� ��� l'• ?}I L^"o"r"' • ,gam }i s ~,.!,�{ ___ - —~�•' -'•�4.
