Rants, Mayor Subject: Albanese Single Family Residence 13305 37th Avenue South Project No. P93 -0076 Review Comments Dear Mr. Albanese: Ross A. Eamst P. E., Director This is a follow up to a telephone conversation I had with your architect, Jeffrey Skutley, on September 14th, and to two tele- phone conversations I had with you, the most recent of which was. on December 3rd. During the above conversations, T described to your architect and you some of the additional information I needed to approve deve- lopment permits for this construction. The following•list identi- fies additional information needed in total: 1. A driveway study needs to be completed. This study needs to address sight distances to assure that safe access onto 37th Avenue South can be constructed. If not, an alterna- tive may be the alley to the west. 2. Once access has been determined, a driveway design needs to be submitted. This design should address such items as grades, type and thickness of surfacing and adequate pro- vision for drainage. 3. The location of the nearest fire hydrant needs to be shown. 4. Quantities of cut, fill, excavation and backfill need to be furnished so that the requirement for a land altering per - mit can be determined and associated fee calculated. 5. The quantity of hauled materials needs to be identified. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: (206) 433.0179 • Fax (206) 431-3665 6.

PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration and geoteclinical engineering study for the proposed single family residence in Tukwila, Washington. The proposed building location and approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 1. In the event that any changes in the nature, design or location of the structure are planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1.1 Purpose and Scope The purpose of this study was to provide geologic and geotechnical data to be utilized in the design and development of the above mentioned project. Our study included a review of available geologic literature, logging of four exploration pits, and performing geologic studies to assess the type, thickness, distribution and physical properties of the subsurface sediments and shallow ground water conditions. Engineering studies were also conducted to determine the type of suitable foundation, allowable soil bearing pressures, anticipated foundation settlements, top of slope setback recommendations, drainage considerations and erosion mitigation. This report summarizes our current field work and offers development recommendations based on our present understanding of the project. 1.2 Authorization Written authorization to proceed with this study was granted by Mr. Darby Dell of Albanese and Associates, Inc. Our study was accomplished in general accordance with our proposal dated March 17, 1992. This report has been prepared for the exclusive use of Albanese and Associates, Inc. and their agents, for specific application to this project. Within the limitations of scope, schedule and budget, our services have been performed in accordance with generally accepted 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 must be understood that no recommendations or engineering design can yield a guarantee of stable slopes. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner. 2.0 PROJECT AND SITE DESCRIPTION This report was completed with an understanding of the project based on conversations with Mr. Darby Dell. Present plans call for a single family residence to utilize conventional wood -frame construction and conventional spread footings. The finish floor elevation is anticipated to be near the existing site elevation in the proposed building area. The property was situated on southwest corner of 37th Avenue South and South 133rd Street at the intersection with U.S. Highway 99, in Tukwila, Washington. A house that previously occupied this lot was raised prior to our visit. No evidence of this structure remained. The parcel was roughly 115 feet (east -west) by 75 feet (north - south), and generally slopes gently downward from the southwest toward the northeast. Steep slopes ranging from approximately 1H:1V (Horizontal:Vertical) to approximately 0.8H:1V and from approximately 10 to 18 feet in height mark the northern and eastern edges of the property. The toe of the southeast slope terminates in rock lined drainage ditches at the edge of 37th Ave. S. and S. 133rd St. An unpaved alley borders the west property line and a single family residence is located to the south. The proposed building location was approximately 15 feet from the top of the northern slope and 48 feet from the top of the slope to the east. No standing or flowing water was observed on the site at the time of our exploration. Vegetation consisted of a few deciduous trees near the top of the slopes and a sparse cover of brambles, berry vines and grass on the slope faces. The building area was recently cleared and a thin growth of new grass was becoming established. No evidence of recent slope movement was observed and erosion was limited to a small denuded area on the north slope where children were said to have been sliding down the slope face. Some very limited indication of embankment incision was observed. It is likely to have been the result of seasonal clearing of the drainage ditch with heavy equipment in past years prior to the placement of the existing quarry rock liner. 3.0 SUBSURFACE EXPLORATION Our field study included geologic logging of four exploration pits (EP), excavated with a tractor - mounted backhoe (provided by the client), to gain shallow subsurface information about the site. The various types of sediments as well as the depths where characteristics of the sediments changed are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed may represent gradational variations between sediment types in the field. The exploration pits were approximately located in the field by measuring from known features, such as the top of slope. A topographic survey or site sketch were not available at the time of our field work. The conclusions and recommendations presented in this report are based on the 4 exploration pits completed for this study. The number, location, and depth of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. • It should be noted that differing subsurface conditions may sometimes be present due to the random nature of deposition and the alteration of topography by past grading and /or filling. 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 to re- evaluate specific recommendations in this report and make appropriate changes. 4.0, SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the field explorations accomplished for this study, visual reconnaissance of the site and review of applicable geologic literature. As shown on the field logs, the exploration holes encountered shallow fill soils overlying natural soils. • The topsoil and fill were generally indistinguishable and consisted of loose /soft, silty sand and sandy silt. The natural soils were generally found to consist of medium dense /stiff, silty sand, and sandy silt over dense /hard, silty sand and sandy silt. Materials encountered in the exploration pits were studied and classified in the field by an engineering geologist from our firm. Selected samples were then transported to our laboratory for further visual classification as necessary. The following section presents more detailed subsurface information. 4.1 Stratigraphy Topsoil and fill soils consisted of loose /soft, moist to wet, dark brown to gray -brown fine to course silty sand and sandy silt with some clay and gravel, ranging in depth from approximately 1 -1/2 to 3 feet. The fill was generally a very organic rich sandy silt, that contained some debris. The topsoil and fill contact was distinguishable only in EP -1, were the fill measured approximately 2 feet over approximately 1 foot of in -place topsoil. Natural soils encountered at 1 -1/2 to 3 feet, were generally weathered in the upper 4 to 6 feet, and consisted of medium dense /stiff, moist, gray to yellow brown and mottled gray and orange - brown, silty sand and sandy silt with some clay and gravel. The density of the natural sediments increased with depth and was generally dense /hard below 3.5 to 6 feet. In EP -4, occasional cobbles and boulders up to 2 feet in diameter were observed. The exploration pits extended to depths ranging from 5 to 10 feet below present surface elevation. The natural sediments are interpreted to be Vashon age lodgement till deposits. The lodgement till was deposited at the sole of the advancing Vashon ice sheet and was glacially consolidated, resulting in a material possessing high strength, low permeability and low compressibility characteristics. 4.2 Hydrology No surface water was observed on the site. However, very li heepage was observed in E and EP -3 excavated on the south side of the lot. The seepage occurred at the contact between' the'frt a c the natural underlying sediments. It should be noted that fluctuations in the level of the ground water may occur due to the time . of the year and variations in rainfall. Seepage may also occur at random depths and directions in non - uniform fills. • April 13, 1992 Project No. 9203 -19G II. GEOLOGIC HAZARDS AND MITIGATIONS 5.0 SLOPE STABILITY CONSIDERATIONS AND SETBACK RECQMMENDATIONS Currently, the proposed residence is located south and west of the slopes which measure 10 to 18 feet vertically with a slope angle slightly greater than 40 degrees. Based on our visual reconnaissance of the slopes, and on the data obtained from the exploration pits, the building area is generally underlain by medium dense /stiff to dense /hard lodgement till sediments below a shallow layer of loose /soft topsoil and fill. Dense /hard till is also exposed on the slope face. Very light ground water seepage was encountered at the contact with the fill soils and the natural sediments in the exploration pits on the south side of the home site. However, no seepage was observed on the slopes. Also, we did not observe any evidence of surficial debris slumps or flows in the upper, loose /soft sediments on or around the project site. Based on these observed sediments (till) and lack of a ground water conditions, it is our opinion that the risk of slope movement on this site is less than that which is generally considered acceptable by current geologic hazard and geotechnical engineering standards. In addition, construction of this project should not have an adverse impact on the existing stability of the slope provided that all the recommendations contained in this report are properly followed. We recommend a minimum setback of 15 feet be maintained from the top of any of the side \ slopes. The top of slope is defined as the-line at which the inclination exceeds 40 percent. We recommend that no grading and /or filling be performed within the 15 foot setback area, excluding minor landscaping. It is imperative that soils excavated from the footings not be placed on or near the slope face. Grading or filling on the slope or within the setback zone may lead to erosion and /or slope instability. Currently, indication of embankment incision is very limited and no active erosion is evident in the existing drainage ditches on the south side of S. 133th St. and the west side of 37th Ave. South. However, future development or other changes in the drainage basin could increase the storm water flow through these drainages. If new development of upland areas direct additional water into these ditches, we suggest discussions with City officials and property owners be initiated to assure mitigation of this potential erosion condition. 6.0 EROSION MITIGATION To mitigate the potential for erosion of sediments, we recommend the following: 1) Construction should proceed during the drier periods of the year and disturbed areas should be re- vegetated as soon as possible. Control of surface discharge during and following development should be performed in order to reduce the hazard of erosion. Care should be taken to insure that surface runoff and domestic discharge will not be directed onto the sloping. areas. All devices used to collect Surface runoff should be directed into a tightlined system which discharges away from slope areas. Uncontrolled discharge on or above the slope areas may promote erosion. Soils which are to be reused around the site should be stored in such a manner as to reduce erosion. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, the use of low stockpiles in flat areas, or the use of silt fences. No grading and /or filling should be performed on slope areas or within the 15 foot setback zone, unless reviewed and approved by Associated Earth Sciences, Inc. To reduce slope erosion, we recommend that the slope faces, that are presently denuded of vegetation be revegetated with hydroseed. This is best accomplished during the start of the growing season, so that the vegetation can become established prior to the rains in the fall. Local hydroseeding firms can provide recommendations for seed mix and application. A silt fence should be placed along the lower elevation of the lot during construction and remain in -place until vegetation is established. April 13, 1992 Project No. 9203 -19G III. DESIGN RECOMMENDATIONS 7.0 INTRODUCTION Our exploration indicates that, from a geotechnical standpoint, the parcel is suitable for the proposed development provided the recommendations contained herein are properly followed. In general, the medium dense /stiff, natural lodgement till sediments will be suitable for foundation support. The bearing stratum is relatively shallow, less than 4 feet below ground surface in all 4 exploration pits. Therefore, conventional spread footings or a deepened spread footing foundation that extends below the topsoil and fill and bear on the medium dense /stiff natural sediments may be utilized. 8.0 SITE PREPARATION Clearing of the site had been completed some time ago, and the only vegetation that had become re- established over the building area was a sparse cover of grass. For a slab -on -grade foundation, site preparation of the building area should include removal of all the upper organic loose /soft topsoil and fill, debris and any other deleterious material. For a crawl space foundation, removal of the upper organic topsoil and fill, debris and any other deleterious material can be accomplished by trenching the foundation footprint. Additionally, any buried utilities should be removed or relocated if they are under the building areas. The resulting depressions should be backfilled with structural fill or compacted clean 2 to 4 inch crushed rock. Seepage was observed in EP -2 and EP -3 on the south side of the lot. The seepage occurred at the contact between the fill and the natural soils: Plans should be made for the collection and redirection of this water, should it be encountered at the time of the foundation excavation, so that it does not seep into the excavation or soften or submerge the bearing soils. Excavation of a shallow ditch partially or totally around the perimeter of the foundation excavation should help to intercept the seepage water and direct the water to the storm system. Water should not be allowed to collect and stand in the foundation excavation, were it could soften the foundation bearing sediments. The footing drain will act to collect this water on a permanent basis. 9.0 FOUNDATIONS Conventional spread footings may be used for building support when founded on medium dense /stiff natural sediments which were encountered at approximately 1 -1/2 to 3 feet below present surface grade. Footings should not be founded in or above the topsoil /fill. We recommend that an allowable bearing pressure of 2,000 pounds per square foot (psf) be utilized for design purposes, including both dead and live loads. An increase of one -third may be used for short -term wind or seismic loading. Perimeter footings should be buried at least 18 inches into the surrounding soil for frost protection. All footings must penetrate to the prescribed bearing stratum and no footing should be founded in or above loose or organic soils. If the prevailing weather is wet, the foundation soils can be protected from disturbance and softening by the placement and compaction of 4 inch thick layer of clean 2 inch crushed rock. Anticipated settlement of footings founded on medium dense lodgement till should be less than 1 inch, However, disturbed soil not removed from footing excavations prior to footing placement could result in increased settlements. All footing areas should be inspected by Associated Earth Sciences, Inc. prior to placing concrete, to verify; the foundation is entirely founded on medium dense /stiff natural sediments, the recommended effective setback distance has been achieved, and that construction conforms with the recommendations contained in this report. Such inspections may be required by the governing municipality. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. 10.0 FLOOR SUPPORT At the time of our study it was not known whether the residence would be constructed with a crawl space type or slab -on -grade floor, therefore recommendations for both follow: In the case of a crawl space type floor construction, the soil below the floor system should be covered with an impervious moisture barrier to reduce dampness. A slab -on -grade floor may be placed over medium dense /stiff natural sediments or on structural fill compacted to a minimum of 90 percent of the modified Proctor maximum dry density (ASTM :D 1557). A polyethylene plastic vapor barrier should be used under floors likely to receive an impermeable floor finish or were passage of water vapor through the floor is undesirable. Based on American Concrete Institute recommendations, we suggest placing a two to three inch layer of clean sand over the vapor barrier to protect the vapor barrier and to allow some 'moisture loss through the bottom of the slab to reduce warping in the curing process. Sand should be used to aid in the fine grading process of the subgrade to provide uniform support under the slab. 11.0 DRAINAGE CONSIDERATIONS All perimeter footings should be provided with a drain at the footing elevation. Drains should consist of rigid, perforated, PVC pipe surrounded by washed pea gravel (see attached Wall /Footing Drain Detail). The level of the perforations in the pipe should be set 2 inches below the bottom of the footing at all locations and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. Roof and surface runoff should not discharge into the footing drain system but should be handled by a separate, rigid tightline drain. The roof drain and footing drain systems can be connected tightline at a point downslope and away from the house. All footing and roof drains should be tightlined to the bottom of the slope and discharged onto a suitable storm drainage system. 8 In planning, exterior grades adjacent to walls should be sloped downward away from the structure to achieve surface drainage. No drains should be allowed to discharge onto or above the slopes. Discharge of water on the sloping areas would promote erosion and reduce the stability of the slopes. 12.0 PROJECT DESIGN AND CONSTRUCTION MONITORING We are available to provide geotechnical engineering and monitoring services during construction. The integrity of the foundation 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 part of this current scope of work. If these services are desired, please let us know and we will prepare a cost proposal. We have enjoyed working with you on this study and are confident that these recommendations will aid in the successful completion of your project.
