I am not sure how the water outside the door will affect you & your husband since this is your in-laws home and I cannot find information about this. Sin Way, JackieLee, Rapanui, or hoemum, & Mentor777 are the people who can assits you more with question.
You can email them directly or send a message thru the forum. Just look for their name in the listings at the Forum. I am sorry

I cannot help more, but these other members have much more experience and will have the answers you need.
