C. QIscuSSIQn of Evaluation The project property is presently level, containing little slope and devoid of any unique physical or topographic features. Development of the site as a solid waste transfer station will not adversely impact the existing conditions of soil, geology, topography, or erosion. The proposed project consists of the construction of a 11,345 square foot transfer station building which will consist of concrete footings, concrete floor and a steel frame, a 2700 square foot office and truck service building of similar character and areas for parking and storage of equipment. As a result of this construction, there will be no unstable earth conditions or changes in geologic substructures. The earth will be disturbed during construction to place the footings and to provide a smooth surface for the placement of concrete and asphalt surfacing. The end result will be a 14,045 square foot area to be placed under cover and an additional 55,000 square feet of paved area. This disruption of the earth during construction will not cause any adverse affects on the environment. There will be a net decrease in wind or water erosion of the soils, since more of the area will be covered by building and pavement and will not be exposed to the elements. Due to the low permeability of the soil on the site and the potential for contamination of runoff, care should be taken to intercept and convey runoff to engineered facilities. - If subgrades are not properly installed or drainage improvements constructed, the shrink/swell potential of the soil, combined with the nature of the proposal could result in failure or cracking of concrete slabs on the site. This kind of failure in the transfer station building itself could result in some soil or groundwater contamination. D. Mitigation Prior to issuance of a building permit, the applicant should be required to submit a soils and geotechnical report to the satisfaction of the City Engineer. Said report shall reference an original investigation of the site regarding the nature of surface and subsurface soils. The report shall contain recommendations and conclusions by a registered civil engineer or certified engineering geologist regarding the nature and extent of foundations, subgrade preparation and the type and location of drainage facilities necessary to avoid failure of improvements due to the nature of soils underlying the site. While no active fault traces underlie the site or the Tracy area, adherence to building code requirements will avoid damage to buildings and other structures due to any seismic activity in the immediate area. 19
