AMC Title 21 establishes the Hillside District with stricter slope, drainage, on-site septic, and tree-retention standards reflecting permafrost-prone soils, wildfire risk, and limited public utility extension above the 1,000-foot contour.
Above roughly the 1,000-foot elevation contour east of Anchorage Bowl, AMC Title 21 imposes Hillside District overlay rules that restrict slopes greater than 25%, require geotechnical soils reports for foundations on permafrost or ice-rich frozen ground, and demand on-site wastewater systems where AWWU sewer is unavailable. Engineered drainage swales protect the Campbell Creek and Rabbit Creek watersheds. The Hillside Tree Conservation provisions of AMC §21.07 require retention of mature spruce and birch over a minimum percentage of each lot, balancing wildfire defensible-space needs with view-corridor protections under the Anchorage 2040 Land Use Plan.
Unpermitted Hillside grading or septic installation violates AMC Title 21 and Title 15 building code, triggering stop-work orders, fines up to $1,000 per day, and required restoration bonds for slope rebuilding.
