THREATNot Understanding
the Resource Lack of knowledge No surveys Unaware of
problems or potential problems
Out of Sight – Out of Mind

MitigationStructures Already in Place Over Caves Identify Most Significant Problems Remove if possible - Replace with state of the art
technology if not possible Reroute sewer lines
New Structures Locate away from cave passages, if possible Double-walled sewer lines No buried gas tanks
Set Standards Determine and enforce environmentally friendly guidelines
for living and working over cave areas

Threat – Bad Practices
Leaking/Overflowing Sewer Lines
No Parking Lot Runoff Filter System
Poor or No Planning Uncontrolled Access No Guidelines for
Entering Caves Releasing Sensitive

Mitigation
Good Planning Documents State of the Art Technology Remove or Reroute When Possible Determine Levels of Access Develop Guidelines for Entering Caves Establish Sensitive Information
Release Guidelines
