Scoring systems evaluate and prioritize mitigation options based on locally-relevant crieria. Mitigation options arise from a hazard risk assessment
Benefits & Problems Addressed
Clarifying goals: Scoring criteria force a focus on factors critical for success.
Defining areas of hazard: High profile protections include life, property, environmental resources and social justice. Cities also review administrative aspects of mitigation such as feasibility, legal requirements, costs, and maintenance.
Defining options: Options are structural (land, detention basins) and non-structural (oning code changes)
Tradeoffs: Scoring sheets allow communities to review tradesoff
Tips & Techniques
Combining with other plans: Align mitigation options with other plans that can include comprehensive/general plans, natural resource plans and acquisitions, publci works and parks.
Financial considerations: Scoring typically includes cost factors. Don't forget land acquisition, buyouts and long term service costs.
Repetitive Loss: Emergency managers now take a sharper look at lessening and refusing funding for repetitive loss (e.g. a property experiences flooding or wildfire damage every year).
Benefit/Cost Review: This is the core of the assessment and asks whether costs are reasonable compared to probable benefits.
