The notices are the primary record. Here are their stated causes by storm, the vocabulary that separates each storm's notices from the baseline, and every sewer notice in the nine windows, searchable, sortable, and traceable to the FDEP portal by its incident number.

Cause and asset are classified from the notice text by fixed rules with precedence power, wet weather, break, blockage, mechanical, third party, storm without mechanism, other. Volumes are stated in about half the notices and are floors.
