" Exhibit "A" FUGRO WEST, INC. 1000 Broadway, Suite 440 Oakland, California 94607 Tel: (510) 268-0461 Fax: (510) 268-0545 February 6, 2009 Proposal No. 09.027 City of Redwood City Housing and Redevelopment Division P.O, Box 391 Redwood City, California 94964 Attention: Ms. Debbi M. Jones-Thomas Subject: Proposal for Geotechnical Study, Heller Street Residential Development 611 Heller Street, Redwood City, California Dear Ms. Jones-Thomas: Fugro West, Inc., (Fugro) is pleased to submit this proposal to the City of Redwood City Housing and Redevelopment Division to perform a geotechnical study for the proposed residential development to be constructed at 611 Heller Street, in Redwood City, California (Site). This scope and cost estimate has been prepared based on the results of our previous Phase I Environmental Site Assessment (Fugro 2007), our discussion with the City, and a brief review of available geologic and geotechnical information in our files. PROJECT DESCRIPTION We understand that the project has not yet been finalized, but will consist of the construction of a residential building at the Site. The relatively flat site is currently vacant. The previous residence, which contained a full basement, was recently demolished. However, the basement was demolished and backfilled without any supporting engineering documentation, thus, the basement backfill is considered to be an "undocumented" fill. Based on the California Geological Survey (CGS) Fault-Rupture Hazards Zones map (i.e., Alquist-Priolo), the project site is not located within an active fault zone. However, according to the State of California Seismic Hazard Zone map of the Palo Alto Quadrangle (2006), the project site is located within a liquefaction zone. In order to adequately assess the liquefaction potential of the project site in accordance with commonly accepted local geotechnical practice, one of our proposed borings at the project site will extend to a depth of approximately 50 feet. In addition, in order to evaluate the condition and degree of compaction of the undocumented fill at the previous basement area, two additional borings will be advanced within the backfilled area to obtain data of the existing moisture and density condition of the fill, and to perform laboratory compaction curves on the fill materials to assist in the evaluation of the relative compaction of the in-place fills.
