I noticed that. It does seem like the problem only touches the edge of the property, but if were in that neighborhood I’d seriously consider investing in infrastructure that reduced flooding, like permeable pavers and rain gardens.

I don't think permeable pavers or rain gardens will do a thing for you when the creek rises.

what creek?

lol i've never heard of a corner lot being a bad thing, usually more desirable, what am i missing? the traffic issue?

Fema new map draws from multiple multiple data bases and includes specific construction information about house and past home owner insurance and flood insurance claims. It is going to be house specific.

Flood Factor is stupid.

A house next to creek with a full basement is rated same as elevated house no basement.

House with five claims rated same as no claims.

House with sump pump and mechanicals upper level rated same as house with no sump pump and heating system in basement.

What a cute little house though. Too bad it's on a corner lot.

Any model, including FEMA’s, will have errors. It’s clear there’s meaningful drainage on this street. No idea how serious it has been, but it’s likely to get worse.

if you don't know the history of the "meaningful drainage" on this street, how can you make that statement?

Thank you for clarifying. Also it seems like the house next door/across the street which is now under contract has the same 9/10 flood factor score. https://www.redfin.com/MD/Chevy-Chase/7900-Glendale-Rd-20815/home/10660852

Is this flood factor information something that's required to be disclosed if the property has never flooded? In other words, is this information "official" enough for disclosure purposes?

I was just thinking the same thing. When you click on the flood factor it says: "There’s a 1% chance of 2.1 ft of water reaching this building this year". 1%? come on.

Keep in mind “this year” means the next 4 months. If you look at 5 years, the probability goes way up to 74%

oh that's interesting. I didn't even notice that information till you pointed it out. Interestingly enough, there's an open house tomorrow!

yes but if DCUM is a microcosm of how the overall home shopper approaches the home search process, then this is a problem. I have seen so many discussions on this forum regarding homes and their "flood factor", and I'm willing to bet there are people on here who have not even bothered looking at a listing that has a flood factor higher than a 4, for example. This is really messed up, and I don't even have any skin in this game!
