Need help with finding flood areas

Sorry, not really sure what to title this. I’m relocating to Houston from the Portland area because my work needs to transfer me. I have heard that some parts of Houston flood way worse than others during hurricanes and what-not, I can’t seem to find a map that shows the risk of flooding for specific areas. If anyone can help me out I would be very appreciative!

I work at the ship port so I have to be within 30 mins of channelview
