Q. What is the impact to the flow of the horizontal curb line IF the catch basin is totally surcharged from storm surface water flowing into it from along the curbs? Note, this total surcharging did occur during the March 2012 event, and it is also substantially full during most heavy storm events.

[CITY] The air gap outside a home is designed to allow for water to escape/discharge from a sump pump in case of an event where the downstream storm lead and/or curb drain is not flowing due to blockage, high flow conditions, etc.

Robert.this is what I SAID LAST NIGHT!

In addition............if the air gap is also for air intake venting... how can it vent if it is buried in the snow....

I just love all of these mixed messages and responses!
