Here at Lake Charles Regional LCH we experienced heavy rain for Hurricane Harvey but were spared of any catastrophic flooding. On Monday we had unrelenting rainfall which caused flooding on the airfield and was getting close the our secondary R/W. Is there any actions that should be taken if water is present in the safety area? We are not talking about puddles of water in a low area, I am talking about complete inundation of water up to but not on the runway surface. We were monitoring the water hourly and were prepared to closed the R/W when the water breached the surface. Luckily, the weather broke and the water receded, but it got me asking questions.
