The Nelson Steep Creek Hazard layer encompasses the outcomes of the Steep Creek Assessment, a comprehensive study conducted to evaluate potential hazards associated with four major creeks in the City of Nelson: Anderson/Fell Creek, Ward Creek, Cottonwood Creek, and Smelter Creek. The identified hazards include floods, debris floods, and debris flows, primarily anticipated in creeks with slopes exceeding 3° (5%).

The assessment also covered key tributaries of Cottonwood Creek, specifically Giveout, Selous, and Gold creeks, situated upstream of the city's municipal boundary. The identified hazards include floods, debris floods, and debris flows, primarily anticipated in creeks with slopes exceeding 3° (5%). The study's objective was to provide the City with updated and prioritized flood and steep creek hazard boundaries, aiding in informed planning and decision-making processes. The methodology employed by BGC involved a thorough desktop review of available aerial imagery, including air photos and satellite imagery, a review of previous reports, and a one-day field reconnaissance visit.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>BGC Report is dated January 2023: https://www.rdck.ca/assets/Services/Emergency~Management/Documents/City%20of%20Nelson_Steep%20Creeks%20Hazard%20Assessment_2023.pdf</SPAN></P></DIV></DIV></DIV>
