Structural Technical Appendix <br />This toolkit document is supported by a Structural Technical Appendix that describes the technical analysis <br />behind these criteria, which are based on structural engineering principles and the California Building <br />and Residential Codes. The Technical Appendix also provides some additional guidance to address non- <br />conforming items, such as when an anchor layout is not based on a solar support component manufacturer’s <br />guidelines, or when a coastal site is located within 200 yards of the ocean (Exposure D). This document can be <br />found online. <br />Probability of Code Compliance <br />The Structural Technical Appendix includes a section that examines the probabilities associated with the <br />assumptions behind Table 1 that allows six feet cross-slope anchor spacing in some circumstances. That <br />statistical analysis estimates that the probability of code noncompliance for six feet anchor spacing is only 2 in <br />a thousand installations (0.2%). Note that probability of structural failure is orders of magnitude lower than <br />the probability of code noncompliance. <br />(Introductory text provided for jurisdiction’s reference only.
