  2. State law delegates authority to local governments to adopt floodplain regulations to protect public health, safety, and welfare.
Section B: Findings of Fact
  1. Special Flood Hazard Areas (SFHAs) in Lincoln County periodically inundate, causing threats to life, property, commerce, services, and the tax base.
  2. Losses are driven by cumulative floodplain development and vulnerable/insufficiently protected uses.
Section C: Statement of Purpose
  1. Restrict/prohibit uses that endanger life, safety, property, or increase flood heights/velocities.
  2. Require flood protection for vulnerable uses and public facilities during initial construction.
  3. Protect buyers from acquiring lands unsuitable for development due to flood hazards.
