<p style="margin:0px 0px 6px;">This dataset represents areas in Jackson County where slopes exceed 20 percent. The data originates from countywide LiDAR elevation models produced by DOGAMI and the 2023 OLC Jackson County lidar project, reprojected to OCRS NAD 83(2011) (2010). City limits and public lands were removed, and polygons were simplified using a minimum area threshold to reduce small artifacts.</p><p style="margin:0px 0px 6px;"></p><p style="margin:0px 0px 6px;">These mapped steep‑slope areas support land‑use planning and review processes, including application of Jackson County Land Development Ordinance (LDO) Section 9.3, which outlines development standards, geotechnical evaluation requirements, and mitigation measures for construction on natural slopes greater than 20 percent.</p><p style="margin:0px 0px 6px;"></p><p style="margin:0px 0px 6px;">For more information, refer to the Jackson County LDO (Section 9.3.1):</p><p style="margin:0px 0px 6px;"></p><p style="margin:0px 0px 6px;"><a target="_blank" rel="noopener noreferrer" href="https://www.jacksoncountyor.gov/Document%20Center/Departments/Development%20Services/Planning%20Land%20Development%20Ordinance/Chapter%209%20-%20General%20Development%20Regulations.pdf?t=202403041659040">https://www.jacksoncountyor.gov/Document%20Center/Departments/Development%20Services/Planning%20Land%20Development%20Ordinance/Chapter%209%20-%20General%20Development%20Regulations.pdf?t=202403041659040</a></p> |
