Landslide hazard awareness guides for californiaproject period: 7 1 2025 6 30 2026LANDSLIDE mapping and landslide hazard awareness has long been a critical component of CGS work

The California Department of Conservation was awarded a $366,310.54 Project Grant from the U.S. Geological Survey's Cooperative Landslide Hazard Mapping and Assessment Program (CFDA 15.821) to develop five new or significantly updated landslide hazard awareness publications for various audiences in California. The project period runs from July 1, 2025 to June 30, 2026.

The five deliverables include: 1) a "What Are Landslides?" fact sheet, 2) a "Landslide Hazards in California" fact sheet, 3) a "Post-Fire Flood and Debris Flow Hazards Guide", 4) a "Forest and Watershed-Based Practices to Reduce Landslide Hazards" fact sheet, and 5) a "California Homeowners Guide to Landslide Hazards". These publications will be designed in an approachable format to increase public and stakeholder awareness of landslide processes, impacts, and mitigation strategies across California.

Thelandslide products created by the CGS form the foundation for all other CGS landslide-related analyses.for instance, CGS landslide maps are a base dataset for cgss development of seismically inducedlandslide zones. The landslide products are also an important source of geoscience data forpractitioners, planners, and emergency responders. However, the CGS understands that there is a needfor increased awareness of landslide hazards in california, and the work that the CGS performs. The cgsstrategic plan (CGS, 2019) identifies the need to increase public and stakeholder engagement through abroader array of products. The objective of this proposal is the development of publications intendedfor outreach and awareness for various audiences (such as planners, emergency responders, homeowners, decision makers) of landslide processes and impacts, and types of landslide hazards incalifornia. The CGS proposes to develop or update five landslide hazard fact sheets. These include the followingfive deliverables: deliverable 1: what are landslides? Fact sheet deliverable 2: landslide hazards in california fact sheet deliverable 3: postfire flood and debris flow hazards guide deliverable 4: forest and watershed-based practices to reduce landslide hazards fact sheet deliverable 5: california homeowners guide to landslide hazardsof these five fact sheets, three will be new fact sheets to make available to the public, while two factsheets, the postfire flood and debris flow hazards guide, and the forest and watershed basedpractices to reduce landslide hazards fact sheet, will be significant updates to existing fact sheets madeavailable by CGS, note 33 (CGS, N.D.) and note 50 (CGS, 2019), respectively. The publications will be in an approachable format within the CGS existing publication series for notes CGS notes (CA.GOV) and will target members of the public, such as homeowners, as well aspartners in planning and emergency response, and decision makers. These publications will bedeveloped with input and feedback from the target audiences to build support and buy-in from thesecommunity members. This will allow CGS to incorporate aspects of these geologic hazards that are ofmost concern to the public, thereby increasing effectiveness and usability of the fact sheets. Othergroups that CGS will reach out to includes partners involved in emergency communication or response. This may include national weather service personnel, state and county emergency managers, countygeologists, or county floodplain managers and planners. The fact sheets will be made available to the public as digital adobe acrobat (PDF) format products onthe CGS website. The CGS will also publish hard copy versions of the fact sheets to make them availableas a routine part of the community outreach events and conferences, as well as CGS offices and thepublic CGS library. The digital versions of the fact sheets will be americans with disabilities actcompliant, and translated to spanish to help ensure they are usable for a wide audience. This proposal submission is a resubmittal of the previous proposal, submitted june 17, 2024, also titled:landslide hazard awareness guides for california. Based on the supportive comments from thereview committee, this proposal now contains a subcontract to social scientist DR. Kristin vandermolenat the desert research institute, a research facility associated with the university of nevada, reno. Hercontributions to public and stakeholder partners will improve the usability outcomes of the proposedlandslide hazard awareness guides. Additional changes from the previous submission include minorchanges in staff composition and their allocated time on this effort.
