Wet-proofing Flood Construction: any advise?

Not sure if they are available online but This Old House has just finished a 6 week season on some of the NJ flood reconstruction with a ton of great ideas using three different methods.

Hi: I am in the beginning stages of planning a major renovation on a house that is recently been included in the 1% flood plain. I have been told I would be required to freeboard the first floor, fill-in the basement, and possibly be compensated with suspension of FAR and zoning height restrictions. Has anyone on the forum gone through the process? How was basement filled? Were you able to build higher and increase SF through an addition.

You are not going to get a generalized answer here. It will depend upon your property. You will need to comply with the newly enacted Flood Resilience Text Amendment.

Wet floodproofing is not feasible for one-story houses because the flooded areas are the living areas. However, many people wet floodproof their basements, garages, and accessory buildings simply by relocating all hard-to-move valuables, such as heavy furniture and electrical outlets. Light or moveable items, like lawn furniture and bicycles, can be moved if there is enough warning. Fuse and electric breaker boxes should be located so you can safely turn the power off to the circuits serving floodprone areas. Another approach is to wet floodproof a crawlspace. If your crawlspace has a furnace in it or is used for storage, these items could be moved to the first or second floor. Vents should be placed on the foundation walls to ensure that floodwaters can get into the crawlspace to equalize water pressure. Wet floodproofing has one advantage over the other approaches: no matter how little you do, you will reduce your damages. Thousands of dollars in damage can be prevented by simply moving furniture and electrical appliances out of a basement. You can go to EZBZ and get bids from local contractors just by posting a free inquiry.
