CAD-based utility mapping by contractor/township engineer
Large sewer & water maps for debt-service (last updated in 2006)
24x36 quarter section mapsets (last updated in 2010)
Engineering plans (from 1950s to current)
Most scanned but not all, some as builts, some missing altogether
Institutional knowledge
Need accurate & reliable data
Duplicate shapefiles, linework off by 20-50ft or more in some cases, missing or incorrect information
Easy to share and update
Outdated bulky quarter section mapsets with handwritten notes at two different locations, nothing to use in the field
Asset inventory & management
No master list of assets, no unique identifiers for the features, no ability to effectively track completed work
True utility networks
No connectivity or flow, missing manholes, valves & hydrants
Sorelle Estates Sub built 1996-2002 in 2 phases
Partial water (ph II), no sewer mapped
But storm, parcels and roads mapped
