Pasadena participates in FEMA's National Flood Insurance Program (NFIP). The city's Engineering Department determines whether properties are in or out of the Special Flood Hazard Area and provides FIRM zone designations and base flood elevation data. Properties in flood zones must meet elevated construction requirements, including raising the finished floor above the base flood elevation. Sec. 9-76(g) allows elevated structures a maximum 5 feet of elevated grade with a maintainable slope to natural ground at the property line. Pasadena's location along the Houston Ship Channel in low-lying Harris County makes it particularly flood-prone. The city has undertaken drainage and flood mitigation projects including lowering roadway elevations for stormwater storage and installing detention ponds. Fences cannot be built within 5 feet of drainage channels, ditches, or bayous per Sec. 9-3(5), and are prohibited on drainage easements of the city, Harris County, TxDOT, or Harris County Flood Control District per Sec. 9-6.
Building in flood zone without compliance: stop-work order. Failure to meet elevation requirements may result in denial of flood insurance.
