Q. It appears that 100% disconnecting in some neighborhoods doesn’t necessarily lead to better outcomes than those with 50% FDDs. Is that true?

A. It is very possible that the findings will show different effectiveness for flow removals from FDDs for the different districts, due to variations in the sub-surface, ground water conditions, and other differences between the districts. It is premature to draw those conclusions at this point, because the flow data presented has not yet been controlled for different rainfall amounts, rainfall patterns and antecedent moisture conditions. Those results will be ready at the next CAC meeting.
