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. CDD 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. has been hired as the contractor.  CDD will develop detailed draft policies and regulations to accompany the draft hazard maps at a later date under a separate contract. At this time, CDD is proposing only the minimum regulatory changes necessary for adoption of the new maps.

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.

Virtual Planning Commission Meeting – August 10, 2021

The CBJ Planning Commission held a public regarding adoption of the Downtown Juneau Landslide and Avalanche Assessment, case#AME2021-0008 at a virtual public meeting on August 10, 2021. The Planning Commission’s Notice of Recommendation to the CBJ Assembly is available in the Documents section below, along with the minutes and Community Development Department and contractor presentations.
