This is a standard surcharge for passenger vehicle traffic. This seems reasonable to me. The wall must be <br />constructed exactly as indicated: <br />L City of Everett Permit Review <br />(1) 28" block EV_ERETT Status: Revisions Approved <br />(2) 41" blocks 05/09/2022 1:33:09 PM <br />I assume that the wall is also designed for a traditional active earth pressure of at least 35 pcf (pounds per cubic <br />foot)..which is why as the wall gets taller the make-up of the blocks change. <br />This all seems reasonable to me. <br />ofnr <br />Dan Say, PE, SE <br />Principal <br />D 206.9563711 <br />O 206.443A212 <br />O STRUCTU AL ENGINE <br />PAGET <br />STRUCTURAL ENGINEERING <br />2124 Third Avenue, Suite 100.
