EXECUTIVE SUMMARY On March 29, 2010, Mr. Steve Shurtliff of DS Consulting, Inc. (DSC) performed a limited inspection and asbestos sampling at 3035 Booth Falls Rd, Vail, Colorado, in order to identify potentially hazardous friable and non-friable asbestos-containing materials (ACM) within the garage of the above-referenced, single-family residence recently scheduled for a renovation. The Colorado Department of Public Health and Environment's (CDPHE) Regulation 8, Part B defines an asbestos-containing material (ACM) as a material containing more than 1% asbestos. Mr. Shurtliff performed asbestos bulk-sampling of drywall (surfacing materials) in a total of three (3) locations within the garage (see Appendix A for sample locations). All three (3) bulk-samples were analyzed by Aerobiology Laboratory Associates, Inc. (NVLAP #200860-0) with all three (3) laboratory results being positive for asbestos at 3% and 4% Chrysotile (see Appendix C for laboratory results). The following sampled materials were found to contain asbestosgreater than 1%(ACM): *Quantities are approximations and subject to field verification. � PROJECT OVERVIEW I. Introduction A limited inspection and bulk-sampling for ACM was conducted at 3035 Booth Falls Rd, Vail, Colorado, by Mr. Shurtliff on March 29, 2010, at the request of Mr. Gary Hill with Hill Constructions Inc. Mr. Shurtliff is a Colorado State Certified Building Inspector; having EPA Accreditation #15413 (see Appendix B for certificate). The purpose of the inspection was to identify, sample and assess potentially hazardous friable and non-friable ACM within the garage of the residence. II. Structural Design The structure is a wood-framed, single-family residence with attached garage. III. Sampling and Analytical Procedures The inspection, assessment and sampling were conducted by an EPA and AHERA accredited Building Inspector qualified by experience, education and training in the recognition of potential ACM and approved bulk-sampling techniques. The asbestos bulk-sampling was conducted on suspect ACM with a limited number of bulk-samples being collected within the residence. The inspection, assessment and sampling were performed in accordance with Environmental Protection Agency/AHERA recommended procedures. These procedures call for the visual inspection of the area of concern and the collection and analysis of representative bulk-samples of suspect material. Some minor destructive sampling was conducted. Walls, columns and perimeter pipe chases were not broken into in order to locate and quantify suspect ACM. It should be noted that additional ACM might be located in these and other inaccessible areas. Random bulk-samples, representative of the suspect asbestos-containing building materials (ACBM) of each homogeneous area (HA), were collected according to the guidelines published as Environmental Protection Agency (EPA) Final Rule: Title II of the Toxic Substances Control Act (TSCA), 15 USC, Sections 2641 through 2654 and in compliance with 40 CFR, Part 763. Representative sampling is based on the following criteria: 1. The distribution of the suspect material throughout the HA. 2. The suspect material's physical characteristics and application. 3. Random sampling patterns determined for each HA. Suspect materials sampled and analyzed should be considered to be representative of materials in each HA if they exhibit similar physical characteristics and the application of the sampled material can be correlated to the application of un-sampled material. Bulk-samples collected were analyzed utilizing the EPA's Method for the Determination of Asbestos in Bulk Building Materials (EPA 600/R/116, July, 1993) and the McCrone Research Institute's The Asbestos Particle Atlas as methods references. Analysis of the bulk-samples was performed on the "date reported," as listed in the bulk-sample analysis report. IV. Notes on Report Format Suspect materials alike in appearance and application were sampled as HAs. Suspect materials were divided into three classifications: 1. Surfacing Material: sprayed or troweled onto structural building member. 2. Thermal System Insulation (TSI): any type of pipe, boiler, tank, or duct insulation. 3. Miscellaneous Material: other suspect materials, floor tile, sheet vinyl/linoleum, ceiling tiles, insulation, and finishing materials. Condition assessments were performed by the accredited inspector at the time of inspection. Condition assessments are listed in the following section. Ratings of "good," "damaged," and "significantly damaged" are meant to indicate the overall condition of the material. A material in "good" condition has no visible damage or deterioration, or showing only very limited damage or deterioration. A material in "damaged" condition has the following characteristics: The surface is crumbling, blistered, water-stained, gouged, marred or otherwise abraded over less than one-tenth of the surface if the damage is evenly distributed (one-quarter if the damage is localized). Accumulation of powder, dust or debris similar in appearance to the suspect material on surfaces beneath the material can be used as confirmatory evidence. A material in "significantly damaged" condition has one or more of the following characteristics: • The surface is crumbling or blistered over at least one-tenth of the surface if the damage is evenly distributed (one-quarter if the damage is localized). • One-tenth (one-quarter, if localized) of the material is hanging from the surface, deteriorated, or showing adhesive failure. • Water stains, gouges, or mars are over at least one-tenth of the surface if the damage is evenly distributed (one-quarter if the damage is localized). Accumulation of powder, dust or debris similar in appearance to the suspect material on surfaces beneath the material can be used as confirmatory evidence. Response-action recommendations for asbestos-containing HAs are listed in the section VII. Recommendations may be for more than one HA, if materials are alike. Recommendations are either "general" or "immediate." An immediate recommendation indicates the presence of asbestos greater than 1% within the bulk-sample, or a bulk-sample in the same HA, and should be addressed accordingly. A general recommendation indicates asbestos does not exist greater than 1% within the bulk-sample, or a bulk-sample in the same HA, and no further abatement activities are required for removal of the material. Any sample reporting a"TRACE" amount of asbestos must be considered to be positive for asbestos greater than 1% unless it is analyzed by the point-count method to be less than 1%. V. Inspector Comments Asbestos was identified during the bulk-sampling conducted at 3035 Booth Falls Rd, Vail, Colorado. A total of three (3) bulk-samples were collected from the garage of the above-referenced residence. Three (3) bulk-samples tested positive greater than 1% for asbestos. ■ Asbestos was identified in the garage wall drywall (surfacing material) sample DW01-01 at 4% Chrysotile 4 Asbestos was identified in the garage wall drywall (surfacing material) sample DW01-02 at 3% Chrysotile Asbestos was identified in the garage wall drywall (surfacing material) sample DW01-03 at 3% Chrysotile VI. Homogeneous Area Descriptions The following section contains sampled HA descriptions and sample locations.

Dear Mr. and Mrs. Adair: As requested by Mr. Tom Sraun of Braun Associates, we are pleased to present this repc�rt describing aur assessment of debris flow hazards retated to the proposed addition to tl�e Adair residence in Vail. Mr. Braun has provided r.c�pies �f the proposed plans prepared by Pure Design Studia, as weli as a topographic �nap of the lot and the surrounding area (Figure 1), prepared by Peak L�d Gonsultants. We also have in our fites hazard mapping from the Town of Vail. Tl�e Adair Residence is located on Lot i2, Block 12, VaiI Village, Thirteenth Filing. According co the Official Debris Fiow Hazard Map adagted by the Town af Vail, an area mapped as "high/moderate hazard dehris flaw area" extends onto the property. This debris flow hazard map is based on the Debris Flow and Debris Avalanche Hazard Anaaysis Map by Arthwr I. Mears (November, 1984). The Adair residence is not located in any other hazard zanes, accarding to the other Town of Vail hazard maps for flood, rockfa!} and avalanche. The pmposed addition involves generally "cantilever", but also standaedlon- grade construction of a new bedroorn wing out over the ma�ped hazarci area, with supporting foundations constructed in the hazard area. Mr. Braun has asked that we address two questions: 1. Will construction of the proposed addition have any negative imgact an tlie debris flow hazard condition that nearby praperties are expased to7 2. Can the drag forces exerted on the proposed foundations installed in the hazard area by predictable debris flow events be reasanably predicted so that the addition can be reasonably engineered tq function in sucl� a d�bris flow event7 We condueted n site visit oa� the afternaon of October 25, 2009. The parpose of this visit was to assess the l�azard conditian, including eonditiaczs upstream and downsh'eam of the property, along the debris flow clianne! and mapped hazard area. We also met with members of the desigi team, to a�cure that �O�Wf1 Of �/8�� O���C COPY � � Mr. and Mrs. John Adair March 10, 2010 Page 2 Thus, in part, this new report is intended to address the above paragraph. We visited the site on the afternoon of October 15, 2009, but have conducted no subsurface investigation (geotechnical drilling and testing) of the site ourselves. We understand that the backyazd of the residence is currently nat accessible for investigation. HP Geotech Findings and Recommendal3ons HP drilled a boring in the existing driveway in October 2007 using 4 inch diameter augers. They report 3 feet of topsoit over loose to medium dense silty sand with gravel and cobbles. They record 4 blows per foot at a depth of 4 feet. Higher blow counts were recorded at regulaz intervals through the remaindez of the boring. They report a denser material containing bou(ders at 14 feet, with avger refusal at I S feet. Appazently, they also experienced refusal at 11 feet, but were able to advance the boring past this location to ultimate refusa! at 15 feet. Groundwater was encountered at 2 feet. HP performed laboratory testing that included a swell consolidation test on one sample, and natural moisture content, dry density, and percent passing the Number 200 standard sieve on two samples. HP discussed foundation bearing canditions, including the difficulties presented by loose wet sands likely to be encounterai in excavatians. They recommenderi a mat foundation for the garage, and indica.ted that dewatering would be required. They made reference to a trench drain they recornmended in an October 7, 1998 report; we do not have a copy of this report and the location or status of this drain is unknown. They also indicate a deep foundation system such as drilled or helical piers would provide lower risk for movement and distress. They do not provide recommendations for such systems, but offer to provide additional recommendations if such systems aze considered. HP provided design recommendations for a mat foundation, as well as surface drainage recommendations. They do not mention or recommend a perimeter dra.in. Ground Conditions and Fowndation Alteraatives The conditions encountered by HP are, in our opinion, consistent with alluvial soils and/or debris flow deposits associated with flaws in aeazby Booth Creek. We note that HP drilled with augers in granular material below the water tabte, thus a"quick" condition could have caused the low blow count (4 blows per foot) they recorded at 4 feet. Nevertheless, we agree with their characterizataon of the alluvium as loose to medium dense. Although they do not log the presence of boulders above 14 feet, the apparent refusal HP encountered at 11 feet suggeSts tb.at boulders may be present closer to the surface; our experience and site observations aIso suggest that boulders (or related difficult drilling conditions) can be present at any deptlz throughout such deposits. The refusal conditions HP encountered at 1 l and 15 feet, along with loose caving soils and shallow groundwater, als� indica#e that Mr. and Mrs. John Adair March 10, 2010 Page 3 conventional drilled pier installation, as well as helical pier instaliatian at this site could be problematic. The mat foundation recommendation is not compatible with the "cantilever" concept for construction of the addition out over the current backyard area, behind the existing garage. Construcrion of a mat foundation in the cuirent backyard area could inerease disruption of large debris flow events; a foundadon systero that allowed "underflow" for this part of the structure would be more consistent with our November 2009 report regarding debris flow hazards and mitigation. Ground conditions in the backyard area have not been investigated, In front of the residence, they have not been investigated below 15 feet. The foundation system employed must be flexible enough so that its design and installation details can be adjusted if differing ground conditions aze encountered. Given the uncertainty of ground conditions, a foundation system where performance can be demonstrated in conjunction with installation is very desirable. We believe a micropile foundation system, installed with a drilling sys#em capable of installing casing and penetrating hazd boulders, is a viable alternative for the proposed addition, for the following reasons: • With the appropriate rock drill, the micropiles can penelrate boulders; where boulders are contacted and penetrated, bond siress (and thus micropile capacity) is usually enhanc�i, not diminished. • With the appmpriate drilling system, the micropile holes can be cased, so groundwater and caving soils do not preclude their installatian. • Micropiles present thin profiles to flow events; if debris flow or other flood events contact exposed micropiles, lateral loads imposed should be relatively small compazed to most other foundation systems. The "superstructure" oi the residence can be constructed at an elevation where its potendal exposure to flow events is reduced, and the possibility that the proposed addition changes flow paths is also reduced. • Micropile depths (as well as drilling and grouting techniques} can be' � adjusted if ground conditions change, thus potentially achieving design capacities without adding new micropiles. • Micropiles aze routinely proof tested in conjunction with installation. This is especially desirable for varying or unknown ground conditions. Thus, we recommend micropile foundations for the Adair addition. We recommend that they be installed by an experienced specialty contractor. We can provide a list of qualified contractors if desired. We also recommend tliat the final design of the micropile foundation system (sometimes called "shop drawings'� be performed by the installer. . Because micropiles are slender foundation eIements, they have limited capacity to resist lateral loads (and the bending stresses that result). However, flexural capacity can be increased by providing permanent steel casing for the Mr. and Mrs. John Adair March 10, 2010 Page 4 portion of the micropile subject to flexure. Gener�l recommend�tions for micropiles specific to the Adair site and analyses related to lateral laads are provided in the following secrions. General Micropile Recommendations The recommendations that follow have been developed to be generally compatible with the "Micropile Design and Constivvction Reference Manual" (FHWA, 2005). Micropiles installed at the Adair site should be designed as friction elements. Unlike what is usually assumed for other deep founda:tions, soil to grout bond stress for micropiles is not purely a"soil property," but can be affecteci by many other variables such as: • the type of drill used, • the way the driller operates the drill, • how the hole is cleaned, • how the hole is grouteri, � grout properties, and • whether second stage gouting is performed. Based on these variables, bond stresses can vary by a factor of 3 or more, in the same or similar ground condirions. Below we reproduce a portian of Tab1e 5-3 from the above referenced manual. We estimate that the mws (for soil types) of the table reproduced below are likely to be compatible with ground canditions on this site (as described by HP, 2008). It is passible that at greater depths, ather ground conditions (including bedrock) could be encountered; however, based on our understanding of site geology, we do not expect any changes in ground condition at depth to lead to lower bond stresses than generalty indicated below. The micrapile contractor should assume a bond stress compatible with reported ground conditions, this table, his seiected installation technique, and his experience. The values provided in this table are ultimate values; a factor of safety of 2.0 is typically applied to compute allowable bond stress. Based on the shuctural plans, we do not believe that group effects need to be considered.

Type D: Primary grout ptaced under gravity head, then one or more phases of secondary "glabaC' pressure gr°ntin8 (from Table 5-3, "Micropile Design and Construction Reference Manual," FHWA (2005)) The structural plans indicate required micropile capacities. The micropile contractor should determine the micropile length based an the required capacity and his expected bond slress. Based on our expectation of the ne;ed for cased holes, we have assumed a micropile diameter of 5.5 inches. If a cantractor considers � different diameter, he should contact us regarding the lateral load considerations in the following section. We recommend that micropiles be proof tested in accordance with pxocedures outlined by FHWA (2Q05), at a rate of not less than 5% (one per 20 micropiles) for each ground condition enc�untered and for each instailation technique used. Currently, the structurai plans indicate 28 micropiles. Thus, if ground conditions do not vary excessively, techniques are not varied, and FHWA's Proc�dures are rigorously followed, two proof tests will be required. We recommend that the micropile contractor assume that two tests will be conducted, with a"deduct" provided if only one is ultimately needed. He should also provide pricing for additional proof tests if required. Tension proof tests are acceptable. Proof tested micropiles can be used as production micropiles if they do not fail. At his discretion, the contractor may . elect to install one or mare sacrificial "verification" micropiles at the beginning of the project as recommended by FHWA. We acknowledge that there are cost implications to the project associated with proof and verification testing. However, given the uneertainties "i,lth g�.o�d conditions discussed above, we regard proof testi.ng as essential to the foundation approach recommended. We do not recommend a micropile foundatian system for this site without proof testing as outlined herein. The contractor's micropile design and caleulations should be provided to our off•tce and the structural engineer for review and comment at least 2 weeks prior Mr. and Mrs. John Adair March 10, 2010 Page 6 to mobilization. For the micropiles along the west side of the proposed addition, Mr. Aldrich will need to check buckling for the exposed portion. The contractor should keep a record of all mxcropile installations that includes the pile designation and/or location, design capacity, design bond stress, design depth, actual depth, drilling tectuuque, ground conditions encountered, time and date drilled, time and date grouted, grouting technique, grout volume for each micropile, and any irregutarities noted. He should also keep a record of all micropile testing. These records should be provided to aur office on an approximate weekly basis during installation. A representative of our office should be on site for at least one day of micropile drilling. The purpose of this observation is to check for indications of differing ground conditions or other irregularities occurring in the installation, as well as to review the contractor's record keeping and testing procedures. Additiona] site observations could be required in the event of irregularities, variable conditions, or failing proaf tests. Lateral Loading The following discussion and analyses apply to the single row of micropiles along the westem edge of the proposed addition to the Adair residence, closest to Booth Creek. As indicated in our November 2009 report, we believe it prudent to consider lateral loads from debris flows on exposed portions of the micropiles in this area. We do not believe it is reasonable to consider debris flow loading an the superstructure. As explained in more detail in our November 2009 report, we believe that only an exfireme debris flow event wauld be large enougb to unpact the superstructure of the residence; it is arguable whether such an event is reasonable to anticipate. Furthermore, it seems unreasonable to design the addition superstructure to a standard that was not used for the older parts of the residence. We checked lateral loading on the micropiles based on pracedures outlined in AASHTO's Standazd Specification for Highway Bridges (AASHTO, 2002). These procedures were developed for highway bridge piers eaposed to cleaz water flow. For this analysis, we assumed a typica.l exposed portion of the micropiie �f 3 feet (vertieally), in general accordance witb our understanding of the arehitechzral and structtu�al plans. We assumed a micropile diameter of 5.5 inches, based on the assumption that micropile holes wili be cased. We assumed an average flow velocity of 15 feet per second, based on reported velocities of other debris flow events ia Colorado (since evaluation of flow velociNes specific to this site was beyond our scope of work for this project). We doubled the ealculated lateral load to conservatively account for higher specific gravity in a debris flow compared to clear water. Based on these assumptions, we calculated a lateral thnist of about 900 lbs. We recommend that this load be assumed to act at 2 feet above gade on each of thc micropiles along the western edge of the addition. Mr. and Mrs. John Adair March 10, 2010 Page 7 We expect that this calculated lateral thrust can be accommodated by vertical micropiles, particularly if they are pravided with a steel casing above grade, and extending below grade as necessary. We recommend a casing thickness of 0.361 inches, and that this casing be extended at least 10 feet below �isting grade. The casing detail should be designed by the specialty contractor. As indicated above, we recommend that the structural engineer, Mr, Aldrich, check buckling for the exposed portion of these micropiles, It may be desirable (architectwally) to cover the exposed portions of the micropiles to change their appeazance. Coverings that would be expected to "tear away" during significant flood or debris flow events should not affect the predicted lateral loading. Permanent coverings that increase the effective diameter of the `� micropiles would be expected to have a proportional effect on lateral laading (that is, doubling the diameter would double the lateral load). Please conta.ct our of�ice for additional analyses or recommendations if such changes are c�nsidered. Other Geotechnical Recommendations HP provided other comments and recommendations related to dewatering of excavations, surface drainage, and backfill compaction. We agree with tl�ese recommendations: 1. Avoid inundation of excavations or slab subgrades during construction. Dewatering should be anticipated for any excavation. 2. Compact backfill to 95% of Standazd Proctor density in pavement or slab areas, and 90% of Standard Proctor density in landscaped areas. 3. Provide a positive slope away from the struchue of at least 12 inches in the first 10 feet in unpaved areas, and at least 3 inches in the first 10 feet in paved azeas. 4. Discharge roof drains and downspouts beyond the limits of backfill. HP did not include evaluation of mold or biological contaminants in their scope of work; neither do we.

Dear Mr. and Mrs. Adair: As requested by Ms. Aldrich of Pure Design Studio, we are pleased to present this repc�rt describing ow recommendations for foundation systems for the proposed addition to the Adair residence in Vail. We previously assessed the debris flow hazard for your proposed addition, and provided mitigation recommendations in a November 13, 2409 re�ort. We have copies of azchitech�ral plans for the addition prepared by Pure Design Studio, as well as structural drawings by Stxuctural Design Solutions. We have discussed the proposed addition and fowndation needs with Mr. Tyler Aldrich, the Slructural Engineez�. The proposed addition involves "cantilever" construction of a new bedroom wing in the backyard area. This construction extends into the debris flow hazard area, and thus was the subject of our report mentioned above. Our November 2009 report concluded that debris impacts were reasonably mitigated by features already in piace in the azea, and that the Adair's proposed addition was unlikely to significantly affeet the debris flow hazard for neighboring properties. Purpose Mr. Aldrich has asked that we address alternative foundation systems for the proposed addition. We discussed the potential advantages of using a micropile foundaiion for the proposed addition, as well as our experience with such syste�ts for the ground conditions believed to be present at the Adair site. Mr. Aldrich asked that we develop micropile recommendadons for the proposed addition. HP Geotech previously investigated the Adair site and made foundat�an recommendations for the proposed addition in a report dated January 9, 2008. Thus the purpose of this (new) report is to provide recomnnendations for amicropiles. Qur Novennber 2009 report included the following paragraph: "Despite the mitigation in place, it would be reasonable and prudent to design the supporting foundation piers for the Adair's propcised addition for debris flow loading. 7`his can be done using reasonably adjusted relationships developed and understood for design of bridge piers for flood flows. We will be pleased to provide this information to your designers when required." . ,.. , . , •., � �r, tarcn ,r�ar ��'�; "-� , � �...Q' � � �r .�:,. �:�,�°^.�...�.. �..�.a,. /: '� � _ _ —' �1nc. 4f , flu� al � � \, ,����,`'��, : ��..� .,..w m ...� .m..�, .,. , «..+ 1 J j 1 � �-� �" / `''� �' - � f ) 1 1 �MitlOirw��i11O�Ar���pp��p� � / •Ah� / / � � ;• /' ' ` a t� 4l���: fln04 • � Ys / rro .'� � � /, � J �� a srr� om'�.fOiiian��+s .�r.� � `.`� � . ` � r � t ' ��e'as�ti."SS'.P�°°" '" • � '�e' �' / ' �� -`/ / � 1 �.�w� �tass�iiN �' � 1 � .ia ae�. +"a��R un+w a w �w� {� \ _ , � � / �`---� y/ l � nm.nr:aww.onss .�sw.�sr j„ ��• Ji % � ' /• / `� � Rmrnlw'e��e.�aaOw�Ylry�aq.aa �.✓ ' i � / 1 ..�.�....�a.aaa....�.m�.,. � � � 1.:1rge f 9wti frF� j j f"�� L���r / � �p plOf 41!

During our site visit we observed evidence of the existing debris flo« hazard: the large inass of elluvial fan debris deposited at closest appraach approximately SO feet norchwest of the Adair residence auring an event in 19$4 (Greg Hatl, Town of Vail Public Works Depariment, personal cnmmunication�. This debris fa�i mass is elongate, approxinnately 400 feet by 70 feet, and is located east-adjacent to the we11-incised, north-south trending Booth Creek. We also observed mitigation/earth-berm features in place, as weti as adjacent and downskream properties. We recognized 2 mitigating earth berms, one located north of the residence near the apex af the alluvial fan and anather imu�eciiately northwest of the residence in the form of an elev�ted service road. These features aze labeled on Figure l of diis report, Based an our site visit we generally agree with the Town of Vsil l�azard mapping. We agree that a debris flow hazard exists for the Adair's lot, and far other lots in the area tl�at `'back up" to IIooih Creek. However, the boundaiy between "moderate" and "13igh" hazard as indicated on d�e Adair Int site plan provided by Peak (which we understand is based on Tawn mapping) does ni�t appear to be associated with any terrain or morphalogical feature. We believe, based on our on-site observations, diat the togical location f�r this boundary is either the service road berm further to the northwest, or the targe remnant of debris further north and west than the service road. Thus, we believe the Adair's proposed addition lies in a"moderate" ��azard area, based on use of that term in tt�e Town of Vait rnapping. Therefore, we believe tliat significant mitigation is alresdy in place for the Adair's existing residence and the proposed addition, cunsisting of: • The lazge mass of alluvial fan debris in place between the existing Bootl� Creek charuiel and the Adair residence, • The weil-incised Booth Creek channel north and west af the Adair residence, • An earth berm near the upstream end or apex of the alluvial fan, tbat we believe, along with the exisring debris, will effectively keep alt bui an extreme debris flaw event within the existing 13aath Creek channel, • The exisring service road berm, that offers secondary protecdon for events that are tazge enaugh to overwhelm the apex berm and/or t�e exisring creek channei described abov�. This mitigatian may liave been put in place en response to fhe previous t 9$4 debris flow event, or may have been put in piace at other dmes or for other purpases. In any event, we believe that the hazard has be6n reasan8bly mitigafed for the Adair's lot.

Drilling in the d�se $ranular soils with auger equipment was diffiicult due to the cobbles and boulders and drilling refusa� was encoemtered in the depasit. �1�OratQrY testyng perf�rmed on samples obtained frotn the 6orings included natwal rrmisture content, density and finer than sard si2e gradation analyses. Resuhs of swell- consolidation testing perfarmed an a relativety undisturbed drive sample ofthe saad s�ils, presented on Figure 4, indicate moderate aimpressibility under conditions of loading an+d wetting• The laborstory testing is sumrnarized in Tabie 1. Groundwater was encountered in the boring at a depth of 2 feet at the time of drilling and the subsoils were very maist to wet. FUUNDATION BCARING CUNDITIUNS The loose and wet sands at the expected excavation depths will create construcc;tion dif�'tculties. We recammend the praposed garage be sapparted on a mat foundation to reduee the risk ofsettlement. Fill piaced ubove the existing graund surf�ce will apply a surcharge loading and should be limited Eo reriuce the dif%xential settlement potential. Exc;avated material should be removed from adjacent the addition atea as the dsgging advances. Dewatering such as with s�umps and pumps wili probab}y be re+quired to ke�p the excavation dry during construction. A trench drain along the northem property line vaas recammended in our October 7, 1998 report, A deeper foundation system, such as drilled or helical piers, that extend into the under�ying gravel soils could alsa be used for support �tnd would provide a iawer risk alternative with regard to poteatial buildin� movements and distress. If a deeper foundation system is �>01192(�Cf @d, we should be cantacted for additional recommendatans.

The design and oonstrudion criteria presented bebw shouid be observed tor a mat foundation system. 1) The f+�undatian shou[ci be designed far ati aHowable bearing pressure of 1,040 psfor a madulus ofsubgrade reaction of 1IX} tc£ Basad on experience, we expect settlement of foundations designed anci canstracted as discusseci in this section wiil be about 1 inch or less. Where the bottom of the mat/sl$h is less than 48 ir►ches below extw-�r grade, the fnund�n can be protected fivm frost by placirig 2 inch thick rigid foam insul�tian (blue board) aut 2 feet from the bottom of the concrete. The bottom of the mat on the thick ends should he at least 1$ inches below exterior �;rade. z) A11 existing fill, f+�nndations and debris fram prior site development, topsoil an�i any loose or disturbed sails should 6e removed and the foundation bearing levei extended down to the untlisturbed natural soils. Voids created from removing targe rocks or unsuitsble soils should be backf'illed with compacted sand arid �ravel or conerete. If water se�pa�;e is ancountered, dewstering such as with sumps and pumps should be provided co ke�p the excavatiQn dry. 3) Struc�ural fill for support of the mat or thickened slab should be com�acted to at least 95% of the maximum star�dard Proctor density at a moisture corrte�nt near optimum. Struetural fiil shoutd consist ofa suitable irnported gtanular material such as 3/4" inch seteened rock. Job No. 107 A744 -' w�P _._ c�c7flB4T'1 -5- 4) A representative af the geotec}tnical engineer should observe all foundation excavatios�s prior to concrete placement to further evatuate bearing conditions. SURFACE DRAINAGE The fiallowing drainage precautions shauld be observed during canstn�ctiQn and maintained �t a!1 times after the addiEion has been completed: 1) inundation ofthe fnundation excavations and undecslab a.reas shouki be avoided during construction. 2} Exterior backfill should be acljusted to near optimum �isture and compacted to at teast 95% of the maximum sta�xlard Proctor density in paveme�t and slab areas and to at le�.st 90% o�the maximum standard Practor d�nsity in landscape areas. 3) The ground surface surrounding the exterior of the buikiing should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the first 10 feet in anpaved areas and s minimum slope of3 inches in the first 10 f�et in paved areas. 4) Roof downspouts and drains should discharge well beyond ttee limits of a11 LIMITATIONS This study has been conducted in accordance with gdneratiy accepted geotechnical engineering principtes and practices in this area at this time.

The headers specified at these locations on the CD set dated 05.07.10 were (2)-1 '/. x 9 1/4 LVL's. During framing we revised these headers to be canstructed with (3)-1 �/ x 7!4 LVL's. This is an adequate structural salution for these headers. If you have questions about this recard, please do not hesitate to call.
