The <br />most significant geologic or seismic hazard is related to the proximity of the site to <br />the Cascadia Subduction Zone (CSZ) and the earthquake effects impacting the site. <br />This site-specific hazard investigation for The Mark at Eugene in Eugene, Oregon, was <br />prepared by Brooke Running, R.G., C.E.G. <br />I fk-=&!!-K-. k!,;.Q <br />0(>1]4' 6/1/ZLt <br />The Mark at Eugene <br />Seismic %azard Study <br />Eugene, Oregon <br />12 <br />January 6, 2026 <br />Project No.: 2251077 <br />Landmark Construction, LLC
