Hollow Concrete Block And Hol- low Clay Tile Buildings: The provi- sions of this chapter are applicable to unreinforced masonry bearing wall one- or two-story buildings constructed of hollow concrete blocks or hollow clay tiles when it can be shown by testing that the block or the units are of bear- ing type and the capacity of the wall in bearing and shear based on net area in contact through bed joints is not less than those allowed for solid bricks. Bonding shall also be verified to the satisfaction of the chief building offi- cial. C. Essential Or Hazardous Facilities: This chapter does not apply to "essen- tial facilities" and "hazardous facilities" as defined in table 23-K of the uniform building code.

Notification Of Building Tenants: A property owner shall notify all ten- ants, in writing, that a structural inves- tigation has been performed and that the report is available for review at the City Building and Safety Division Office, 200 Old Bernal Avenue, Pleasanton, California. This notice shall be sent within thirty (30) days of the date the structural engineering report is submitted to the city. (Ord. 1869 § 14, 2002; Ord. 1563 § 1, 1992) 20.52.080 Structural Engineering Reports: A. Preparation Of Reports: A proper- ty owner shall employ a civil or struc- tural engineer to perform the necessary investigation and analysis of an owner's building as set forth below. B. Purpose: The purpose of the re- port is to investigate in a thorough and unambiguous fashion the building's structural systems that resist the forces imposed by earthquakes and to deter- mine if any individual portion or com- bination of these systems is inadequate to prevent a structural failure based on the criteria contained in appendix B. C. Format Of The Report: The fol- lowing is an outline of the format each structural engineering report should follow. This format is not a rigid set of requirements but, instead, provides a framework within which individual ap- proaches to assembling the required information may be accomplished while also allowing the city to evaluate the completeness of each report. 1. General Information: A descrip- tion of the building including: a) the street address; b) the type of occupancy and uses within the building; c) plans and elevations showing the type and extent of lateral force resisting elements in the building; d) a description of the type of construction materials used in the structural systems and information regarding their present conditions; and e) the date of original construction, if known. 2. Investigation And Evaluation Of Structural System: The items to be in- vestigated and methods of investigation (Pleasanton April 2003) 734-4
