Design - Background
After recent hurricanes, residents said they experienced area flooding which would have inundated their homes, if it had been just a bit higher. Therefore, they believe that in a future hurricane, the additional water due to the new impervious road surface could trigger serious home flooding.
Discussing this in 2018, city officials admitted that after Hurricane Irma:
-
The canal east of The Preserve (where the city wants to dump the stormwater that lands on the new road) was cresting.
-
The walking path adjacent to the canal was also flooded.
-
When the new road is in place, storms of that magnitude could trigger serious widespread flooding.
-
We have experienced two storms in recent years that exceeded the 25-year storm criteria by a wide margin.
Speaking "truth to power", a city official candidly admitted "… if we get 150-year storms like we've been experiencing now and again, then the water is going to go to where it tries to go just naturally".
After further discussion, it was agreed that before beginning the road design, the city would undertake a preliminary design of a stormwater system to verify the road could be built without increasing the flood risk. See next page for discussion of this approach, which I call Design #1.
