Lessons Learned•

Marketing “compliance” to “exemptions”

•

Audit form technical and difficult to interpret - Dynamic graphical report needed

•

Point of violation difficult to enforcement residential•

Not all properties are clearly addressed

- Condominiums- Commercial Buildings (Example: Pump house)

•

Database needs to be more comprehensive•

Staffing: ECAD “Program” management along with engineering and technical support
