Keller's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Keller, Texas, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Citations up to $2,000 per day for unpermitted floodplain development. Noncompliant structures risk removal orders, federal penalties, and loss of NFIP eligibility for the property.

This is one of the stricter rules in Keller's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
