JOB NO.: A0035-0175-221 <br />SUBJECT: SEISMIC LOADS <br />PROJECT: Matthew Nelson Residence <br />CHECK INCREASE IN OVERALL SEISMIC LOADS <br />10.3 psf <br />2.3 psf <br />10% <br />10.5 psf <br />2.2% <br />Equiv. Total Dead Load <br />Estimated Roof Dead Load <br />Solar Dead Load <br />% Roof Covered <br />Conservatively neglecting the weight of existing wall materials, the installation of the solar panels represents an <br />increase in the total weight (and resulting seismic load) of 2.2%. Because the increase is less than 10%, this <br />addition meets the requirements of the exception in Section 503.4 of the 2019 CEBC. Thus the existing structure <br />is permitted to remain unaltered. <br />Addt'l Seismic Weight <br />Page 3 of 8 <br />2226 N Hathaway <br />St05/23/22
