Estimating High Groundwater Levels

Engineers and others must estimate high groundwater levels for the proper design of on-site septic systems and other purposes. The following information will help with those estimations:

Note that the key to the maps differ slightly from older maps as follows:
Zone A - Annual range 0.0 to 1.99 feet
Zone B - Annual range 2.0 to 2.99 feet
Zone C - Annual range 3.0 to 3.99 feet
Zone D - Annual range 4.0 to 4.99 feet
Zone E - Annual range 5.0 to 6.0 feet
