FUNDING – BEGINNING OF THE END
• 2007 Safe Artificial Slope Construction Act introduced in the State General Assembly • Linked maps to regulations • Questions about disclosure in Real Estate
transactions • Never approved, but changed perception
FUNDING – MIDDLE OF THE END
• 2010 Elections • Change in majority ideologies in the General
Assembly toward less government involvement
FUNDING – THE END
• 2011 Budget Shortfalls • Recession impacted NC budget – must be
balanced • Growing opposition to the maps due to
misunderstandings • Perhaps politics
Stability Index Map – where landslides might start
Potential Debris Flow Pathways Map – where landslides might go
Slope Movements - Slope Movement Deposits Map – where landslides have occurred or are occurring.

research community or county personnel • Presentation of final maps to county, their guests, and
Emergency Management • Training workshop for county GIS staff
