BLACK AVENUE RESIDENTIAL DEVELOPMENT 648-26-1 Page 1 Type of Services Preliminary Geotechnical Investigation Project Name Black Avenue Residential Development Location 4400 Black Avenue Pleasanton, California SECTION 1: INTRODUCTION This preliminary geotechnical report was prepared for the sole use of TTLC Management, Inc. and Arizona Corporationfor the property located at 4400 Black Avenue in Pleasanton, California. The purpose of this study was to evaluate the existing subsurface conditions and develop an opinion regarding potential geotechnical concerns that could impact the proposed development. The preliminary geotechnical recommendations contained in this report are for your forward planning, cost estimating, and preliminary project design. 1.1 PROJECT DESCRIPTION The project site is located at 4400 Black Avenue in Pleasanton, California. The site is currently occupied by a commercial building with surrounding at-grade parking. We understand that a single- or multi-family family residential development is currently planned for the site. From prior experience, we anticipate the planned development will be two- to three-story, at- grade structures. We anticipate the structures will be of wood-frame construction supported on shallow foundations. Appurtenant parking, utilities, landscaping and other improvements necessary for site development are also likely planned. Structural loads are not currently known for the proposed structures; however, structural loads are expected to be typical of similar type structures. We assume grading would consist of minor cuts and fills across the relatively flat site. 1.2 SCOPE OF SERVICES Our scope of services was presented in our proposal dated March 31, 2022, and consisted of field and laboratory programs to evaluate physical and engineering properties of the subsurface soils, preliminary engineering analysis to prepare recommendations for site work and grading, This preliminary geotechnical report was prepared for the sole use of TTLC ManagementThis preliminary geotechnical report was prepared for the sole use of TTLC Management the property located at 4400 Black Avethe property located at 4400 Black Avenue The purpose of this study was to evaluate the existing subsurface conditions and develop an The purpose of this study was to evaluate the existing subsurface conditions and develop an opinion regarding potential geotechnical concerns that could impact the proposed development. opinion regarding potential geotechnical concerns that could impact the proposed development.
