LP Field floods: Should we be surprised?

I just saw WSMV’s helicopter fly over LP Field and show its field-level under water. As I recall that the field level is actually a “pit” — think about it if you’re familiar with the stadium: You walk into the stadium at “ground level” and the field is two lower-level sections below you. And I seemed to recall some issues related to the lower level of the stadium being in a flood zone.

A google search revealed this:

In 2007, Titans Senior Executive Vice President Steve Underwood told the Nashville Sports Authority that flooding to “service level” of LP Field could be particularly damaging due to the expensive equipment contained there. Quote contained in the minutes (PDF) of a 2007 Nashville Sports Authority meeting in Section 2, the “LP Field Report” regarding the requirement of flood insurance for LP Field.

”Mr. Underwood informed the Board that, under thestadium lease agreement, Metro is required to keep $25 million of flood and earthquakeinsurance. Ms. Abbie Hudgens, Metro’s Risk Management Director, stated that Metrohas a commercial property insurance policy with a $100 million limit for floods. This would apply to the Titans practice facility at Metro Center because it does not lie in a flood zone. Because a portion of LP Field does sit in a flood zone, it has a $25 million insurance limit in the event of a flood. Ms. Hudgens noted that Metro’s property insurers recommended that a flood mitigation plan be implemented at LP Field.

I wonder if that flood mitigation plan was ever implemented? Also, that Titans practice facility at Metro Center that does not lie in a flood zone is also a few inches from being flooded.
