DE Geologic Information Resource Map - Elevation, Water Table, Wetlands, etc.

It says it is 'Beta' but it is not. It is somewhat cumbersome to learn how to use, but very useful to find the elevation and water level for almost any spot.
Also on the right side of the map are different layers, such as wetland types, wellhead protection areas, etc.

Coastal Inundation 7 ft Map - Delaware
- Summary
LiDAR based 1-m DEM was used to develop new bathtub-model sea-level rise(SLR) coastal inundations maps for the State of Delaware.
LiDAR based 1-m DEM was used to develop new bathtub-model coastal inundation maps for the state of Delaware. Inundation maps include surfaces from Mean Higher-High Water (MHHW) to 7 feet above MHHW, in 1-foot increments. These maps will help assess the potential impacts of sea-level rise, storm surges, and numerous other applications and will advise long-range planning of infrastructure, facilities, land management, land use, and capital spending.
