Landslide and Avalanche Assessment

Project Overview

CBJ’s current hazard maps, adopted in 1987 for downtown Juneau, are based on maps created in the 1970s. These low-resolution maps combine landslide and avalanche areas into a single map which identifies moderate and severe hazard areas. The adopted 1987 maps are available here.

In 2018, the CBJ Community Development Department received a grant from the Federal Emergency Management Agency (FEMA) to update these maps with current scientific analysis, and to evaluate landslide and avalanche areas separately. Tetra Tech Inc. was hired as the contractor. Tetra Tech provided a first draft assessment in May 2021 with new maps.  In April 2022 Tetra Tech provided a final assessment with minor revisions to the primary document and maps, and supplemental memorandums. The contract with Tetra Tech expired on April 30, 2022. The grant expired on September 30, 2022.

The final assessment includes updated maps, memorandums with background information on areas of special concern, and a memorandum that explains how to interpret the maps. The assessment is for informational purposes at this time.

Virtual CBJ Assembly Meeting – September 21, 2021

On September 20, 2021, the CBJ Assembly reviewed the draft Landslide and Avalanche Assessment at a virtual Committee of the Whole work session. The Committee did not take public testimony and did not take a vote. The Assembly generally recommended developing additional technical information and public outreach for the assessment; gathering more information regarding potential impacts on home values and insurance; and presenting regulatory, policy, and mitigation recommendations for adoption at the same time as the final hazard assessment. Assembly minutes are included in the documents section. CDD is currently moving forward with these recommendations.
