Wet Weather Window
The Department of Environmental Health (DEH) oversees wet weather groundwater investigations to verify adequate separation between the bottom of a dispersal field and seasonal high groundwater.
The wet weather window will open for a 30-day period when at least 60% of historical seasonal average rainfall has occurred, and 14% of that average has occurred in the last 30 days. The window will be extended for two-week periods provided that at the end of each testing period, at least 14% of historical seasonal average rainfall has occurred in the previous 30 days.
The following table will be updated periodically in the event that a wet weather window is opened:
| Region | Status | Start Date | End Date |
|---|---|---|---|
| North County | Open | 2-7-19 | 4-8-19 |
| South County | Open | 2-7-19 | 4-23-19 |
| East Valley | Open | 3-22-19 | 4-23-19 |
| West Valley | Open | 3-8-19 | 4-8-19 |
