These plans are high accuracy GIS with aspects meeting Survey Standards.  The plans are intended for planning purposes. The plan includes the following layers:
- Boundary – The property lines and easement line depicted are based on the plans of record put into place with traverse and GPS measurements.
- Image – A recent drone orthophotograph is in the background on a layer than can be frozen.
- Planimetry – The planimetric line work from the 2000 aerial topographical maps partially augmented with various updates.
- Topography – Aerial LiDAR derived topography from the 2011 and 2013 datasets from the USGS augmented with various updates.
- Utility – When available, utility locations are included.  These are the most difficult as most are buried.
- Wetland - The wetland locations are based on the best aerial evidence.
