W -7341 Cellular One 101 Elliott Avenue, Suite 435 Seattle, Washington 98109 Attention: Mr. Dave Ruggi, Project Manager Subject: Limited Geotechnical Engineering Study Proposed Communications Tower, Allentown Site Tukwila, Washington Gentlemen: This letter presents the results of our Subsurface Exploration and Limited Geotechnical Engineering Study conducted at the above referenced project. This scope of work is limited to design recommendations for drilled piers for the tower, and foundation support for the modular building, per our proposal, P -3329. Authorization to proceed with this study was granted by Mr. Dave Ruggi of Cellular One on 18 December 1990. This report has been prepared for the exclusive use of Cellular One, and their agents, for specific application to this project, in accordance with generally accepted geotechnical engineering practices. SITE AND PROJECT DESCRIPTION The site is presently a vacant lot located between 12224 and 12234 51st Place South, Tukwila, Washington as shown on the Site Vicinity Map, Figure 1. To the east of the site is approximately a 4 to 10 foot high embankment with trailer parking located on top of the embankment. The site was generally vegetated with weeds with some bushes. Along the fence line located at the eastern property line were blackberry bushes. We understand that at this time a 100 foot wooden monopole is to built on the site, with a small equipment building. Cellular One 3 January 1991 W -7341 Page 2 SUBSURFACE CONDITIONS One test boring was advanced a total depth of 33 -1/2 feet on 2 January 1991. The location of the boring is approximately as shown on the attached Site and Exploration Plan, Figure 2. Drilling was performed using a hollow stem auger and samples were obtained by using the Standard Penetration Test Procedure as determined by ASTM:D 1586. The samples collected were taken to our laboratory for visual classification. The log for this boring is presented at the end of this letter report. The soils at the boring location consisted of approximately 1 foot of topsoil underlain by approximately a 6 foot layer of medium stiff, sandy silt. Below the sandy silt layer was generally a sand with some silt with silty sand seams. This layer was very loose from approximately 7 to 11 feet, grading to medium dense to a depth of 16 feet then grading to dense from 16 feet to the bottom of the boring at 33 -1/2 feet. Groundwater, at the time of exploration, was observed to be at approximately 7 feet. Groundwater levels may vary with changes in precipitation, season, site•usage, and other factors. CONCLUSIONS AND RECOMMENDATIONS The proposed project presently consists of a 100 -foot wooden tower located just south of an existing residence at 12224 51st Place South in Tukwila, Washington. The subsurface conditions disclosed by our borings are adequate for supporting tower foundations and a small equipment building. We recommend utilizing an allowable bearing pressure of 1500 pounds per square foot (psf) for foundations bearing directly upon the undisturbed, native medium stiff sandy silt to silty sand. A minimum embedment of 18 inches below ground surface is recommended for frost protection. We understand that the foundation for the tower may consist of a drilled pier in order to provide uplift and horizontal resistance. We recommend that the drilled piers be embedded at least 10 feet below ground surface. For vertical loading, the recommended value for bearing capacity is 0.9 D /B, in tons per square foot (tsf) for piers embedded from 10 to 17 feet deep, where D is the embedment depth (in feet) below 10 feet and B is the diameter of the pier in feet. For piers embedded below 17 feet a bearing capacity of 1.8 D/B tsf may be utilized. The ultimate end bearing capacity for the pier embedded below 17 feet is 17 tsf for piers embedded at least 8 pier diameters below 17 feet. • • Cellular One W -7341 3 January 1991 Page 3 For frictional resistance, acting both downward and in uplift, we recommend using an allowable skin friction of 0.03 tsf for the upper 10 feet, 0.07 tsf from 10 to 17 feet deep and 0.13 tsf from 17 to 35 feet. The frictional resistance applies to that portion of the pier embedded below 3 feet. Due to the water table, the pier should be designed to withstand hydrostatic uplift pressure from 7 feet below ground surface. For lateral pressures, we assume the pier would be relatively rigid and would act as a pole. Interaction between a pole and the soil is complex and may be modelled by elastic methods. The passive pressure approach presented herein is more straight forward and is conservative by neglecting redistribution of vertical stress and shear at the pier bottom and below the point of fixity, which would likewise serve to resist lateral loads. We therefore recommend using an allowable passive pressure of 175 pounds per cubic foot (pcf), expressed as an equivalent fluid weight, acting over 2 pile diameters wide and 8 pile diameters deep, neglecting the uppermost 3 feet of embedment below the ground surface. According to NAVFAC Design Manual 7 -2, a lateral deflection equal to about 0.02 times the pier length would be required to mobilize the allowable passive pressure presented above. Higher deflections would mobilize higher passive pressure. A factor of safety with respect to ultimate available passive pressure is greater than 1.5, which is commonly applied to transient or seismic loads. Due to the relatively shallow water table and the loose nature of the upper sands, we anticipate a drilled pier hole would be highly susceptible to caving. The hole would also be susceptible to bottom disturbance from the high water table in the sand. For these reasons, we anticipate that the pier hole will need to be cased for the majority of its depth. No more than about 1 inch of sloughed material should remain in the hole prior to concrete placement. Water or an appropriate slurry mix should be maintained within the casing to prevent bottom heave. The concrete would need to be tremied to prevent segregation. We recommend we be contacted to review any alternative construction methods proposed by the contractor. • • Cellular One W -7341 3 January 1991 Page 4 We trust this letter is sufficient for your current needs. We will be able to review the final pier design using the above parameters or to refine these estimates based on specific pier diameters and lengths, as well as provide construction observation services and to answer any questions you may have.

Does the proposal lie within an area designated on the City's Comprehensive Land Use Policy Plan Map as environmentally sensitive. No. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one) hilly, steep slopes, mountainous, other rolling, b. What is the steepest slope on the site (approximate percent slope) ? Less than 2% on site. Northeast of the site is an approximately 15 foot high railroad embankment. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The soils at the site of the soils test boring consisted of approximately 1 foot of topsoil underlain by approximately a 6 foot layer of medium stiff, sandy silt. Below the sandy silt layer was generally a sand with some silt with silty sand seams. This layer was very loose from approximately 7 to 11 feet, grading to medium dense to a depth of 16 feet to the bottom of the boring at 33 1/2 feet. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No surface indications of unstable soils are present. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Some clearing will occur to remove grass and shrubs. Most of the clearing will have occurred for the construction of the temporary cell site consisting of a wooden telephone pole and 12'X 28' electronic equipment vault. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. A minimal area of approximately 2,500 square feet of area will be cleared. A temporary erosion control fence will be added around the southeast and northeast portions of the leased site to filter silt and sediment. Storm water is expected to sheet flow to an existing open ditch conveyance system to the 3 g- northeast side of the site, or to be absorbed into the ground. The site is flat, and not susceptible to erosion by its topography. If erosion occurs during construction, straw bales or other erosion control materials will be placed at the edge of the property line to filter out any sediments that result from construction. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt, or buildings)? The permanent facilities will introduce approximately 350 square feet of impervious surface for the electronic equipment vault and base of the wooden telephone pole. The balance of the site will be covered with gravel, shrubs and grasses. The property contains 10,005 square feet. The cellular facility will add 350 additional square feet of impervious surface for a total coverage of approximately 3.5% square feet of the entire property. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Typical erosion and sedimentation control measures (hay bail or other appropriate materials and a temporary erosion control fence on the northeast and southeast portions of the site) will be implemented in accordance with City regulations for the building permit. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Light vehicular traffic during 4 to 6 weeks of construction. Approximately one trip every other week (2 vehicle trips per month) will be generated by the facility for maintenance purposes. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. None known. c. Proposed measures to reduce or control emissions or other impacts to air, if any: None. 3. Water 4 • 1 a. Surface 1) Is there any surface water body on or in the immediate vicinity of the site (including year -round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The Duwamish River is located approximately a quarter of a mile north of the site. The site does not lie within a floodway or floodplain of this river. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Not applicable 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. 5) Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. No 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. This is an unmanned site and requires no waste disposal. b. Ground 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic Sewage; industrial, containing the following 5 • • chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. No waste material is produced by this proposal. The site is unmanned, thus no water or sanitary sewage service is required. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Negligible runoff will result from the addition of approximately 350 square feet of impervious area around the base of the permanent pole and under the electronic equipment vault. There is an open ditch conveyance system on the northeast side of the site which will handle roof runoff. 2) Could waste materials enter ground or surface waters? If so, generally describe. No waste materials will be generated on the proposed site. d. Proposed measures to reduce or control surface, ground and runoff water impacts, if any: A temporary erosion fence will be installed during the construction of the site. It will consist of a mesh fence 1' into the ground and extending 3' above ground. Granular rock will be placed on top of the mesh fencing to help filter silt and sediment caused by water runoff. There is an open ditch conveyance system on the northeast side of the site which will handle roof runoff. 4. Plants a. Check or circle type of vegetation found on the site: deciduous tree: alder, maple, aspen, other _X_ evergreen tree: fir, cedar, pine, other X shrubs _X_ grass pasture crop or grain wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation 6 • • b. What kind and amount of vegetation will be removed or altered? The construction of the wooden telephone pole and installation of the electronic equipment shelter will require removal of grasses, berry vines and shrubs. c. List threatened or endangered species known to be on or near the site. None known. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Landscaping will be placed around the perimeter of the cellular facility to provide screening for the electronic equipment vault and the base of the wooden telephone pole. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: birds: hawk, heron, eagle, , bir , other: mammals: deer, bear, elk, beaver, other: fish: bass, salmon, trout, herring, shellfish, other doers , cats b. List any threatened or endangered species known to be on or near the site. None known c. Is the site part of a migration route? If so, explain. Not known d. Proposed measures to preserve or enhance wildlife, if any: Not applicable 6. Energy and Natural Resources a. What kinds of energy (electrical, natural gas, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used or heating, manufacturing, etc. Electrical. The telephone pole will require 20 -40 watt service. There will initially be 12 directional antennas 7 • • located on the top of the pole. Electricity and telephone service for electronic equipment will be necessary. b. Would your project affect the potential use of solar energy impacts, if any: No. The wooden telephone pole will not obstruct sunlight from other structures. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: None 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. No material that could cause fire or explosion are known. Cellular radio power density levels are regulated by government as a potential environmental concern. Radio frequency emissions from the Allentown "cell site" facility will be at 869 to 880 megahertz and 18 gigahertz for the radio link transmissions to the mobile telephone switching office in Seattle. The transmissions will be low power with less than 45 watts for cellular radios and 0.1 watts for the 18 gigahertz radio link. As such, the radio frequency power density levels near the cellular telephone pole (10 feet above ground below the telephone pole) will be extremely low and several magnitudes below existing maximum permissible human exposure standards. The maximum cellular radio transmission radio frequency power density will be 1.3 microwatts per square centimeter at the telephone pole base while the maximum 18 gigahertz radio link radio frequency power density would be less than 0.0014 microwatts per square centimeter. By comparison the recommended maximum exposure levels by the Federal Communications Commission and American National Standards Institute (ANSI) are 2,800 microwatts per square centimeter. King County, for instance, has proposed a much more conservative standard of 200 microwatts per square centimeter which still exceeds the highest level emitted by the proposed Allentown "cell site" by a factor of 154. 8 1 2 ) • • These very low power levels and ultra high frequencies at which the "cell site" transmissions occur also eliminate any potential for interference to other electronic devices such as radio, television, VCR's, telephone and medical devices such as pacemakers (which are internally shielded by the manufacturers to withstand over 2,800 microwatts /sq. centimeter. This is born out by our cellular telephone network which has experienced no reported cases of interference to such devices. More over, should any obscure circumstances result in interference from the cell site transmissions the Federal Communications Commission exercises absolute and exclusive authority to require us to immediately correct any such interference even if it means turning off the offending transmitter. Describe special emergency services that might be required. None required. Emergency services will be enhanced by cellular phone service by providing emergency service vehicles with mobile communications potential. Proposed measures to reduce or control environmental health hazards, if any: None are anticipated to be necessary. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other) . 2 3 None. The existing noises will not affect this project. What types and levels of noise would be created by or associated with the project on a short -term or a long- term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. There will be some traffic noise associated with the installation of the cellular telephone pole and electronic equipment vault which will occur during the four to six week construction period. Minimal noise impact shall be generated by the cell site and would consist of twice monthly maintenance visits and sound from the air conditioning units in the electronic equipment vault. Proposed measures to reduce or control noise impacts, if any: 9 • • Hours of construction will be limited to between 7:00 AM and 7:00 PM, Monday through Saturday. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The property currently contains approximately 1/3 of an existing house on the northern property line. The remainder of the property is a vacant lot. North - single family home South - single family home West - single family home East - Northern Pacific Railroad right -of -way b. Has the site been used for agriculture? If so, describe. No c. Describe any structures on the site. The southern 1/3 of an existing single family home. d. Will any structures be demolished? If so, what? No e. What is the current zoning classification of the site? M -2 (Heavy Industrial) f. If applicable, what is the current comprehensive plan designation of the site? Heavy industrial g. If applicable, what is the current shoreline master program designation of the site? Not applicable h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. No i . Approximately how many people would reside or work in the completed project? None. This site will be unmanned. Semi - monthly maintenance visits will involve one person. 10 J • • Approximately how many people would the completed project displace? None k. Proposed measures to avoid or reduce displacement impacts, if any: None 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The immediate surrounding land uses to the west, north and south are single family residential houses. However, approximately 100 feet to the northwest on 51st Place S is a construction company (see photos). Along the eastern side of the site is located the Northern Pacific Railroad Trucking Company (see photos). The pole and equipment vault would be compatible with these uses. Wooden telephone poles presently exist in the immediate area of the site. The cellular telephone pole would be compatible with these existing poles. The site will be located at the rear of the property as far away from the single family residences as possible.
