Lake Inspection Need
• Efficient data collection prior to inspection• Decrease time in field • Little commitment in office upon return• Keep re-inspections to a minimum• Improved quality product for customer
![Page 11: GIS: Improvements to DNR Permitting and Floodplain Management Lacey Duncan May 2012](https://reader035.vdocuments.us/reader035/viewer/2022062500/568153dc550346895dc1d580/html5/thumbnails/11.jpg)
Inspection Preparation
• Prepare lake sketch– Identify 250’ range for site
• Locate staff gage and legal lake level data• Research relevant permits
– Shoreline Classification– Permitted Seawalls– Unresolved Violations
