The IRP outlines a three-tier approach—adapted from FEMA’s post-disaster recovery structure—to help organize work and reduce conflicts between concurrent projects.
Tier 1: Emergency Stabilization (Completed at the Time of Study)
Activities included clearing debris and hazardous vegetation, restoring limited emergency access, and implementing early slope protection measures. These actions addressed immediate safety concerns.
Tier 2: Restoration of Essential Services (Ongoing)
This tier focuses on reconnecting utilities to rebuilt homes, repairing key transportation corridors, reestablishing stormwater capacity, and coordinating trenching activities to reduce repeated disruptions. The timing of Tier 2 work depends on individual rebuild timelines, utility needs, and available resources.
Tier 3: Long-Term Resilience and Modernization (Ongoing)
Tier 3 describes potential strategies to strengthen infrastructure conditions over the long term, such as undergrounding select utilities where feasible, modernizing electrical and water systems, expanding stormwater and drainage capacity, restoring native vegetation to stabilize slopes, and coordinating future work through joint-trench construction where practical. Implementation of Tier 3 concepts will require additional funding, interagency coordination, and further project development.
