Proposed Changes to Houston’s Building


Below is an overview of the changes:

Houston’s current code only applies to property in the 100-year floodplain and protects 1 foot above 100-year flood elevation. The proposed revisions would include property in the 500-year floodplain and protect “X” feet of 500-year flood elevation. It would also include no net fill in the 500-year floodplain.


“X” feet in the proposed revisions is┬ástill to be determined following the public input period. It is believed that the City is looking at changing the ordinance to 2 feet above the 500-year floodplain, but the City would like input on if that is too much or too little.

The 100-year floodplain is land that is predicted to flood during a 100-year storm, which has a 1% chance of occurring in any given year. The 500-year floodplain has a .2% chance of occurring. For residents outside of the 100-year and 500-year floodplain, these changes to the ordinance will have little or no effect.
