The 1999 flood maps that the city reverted to after Hurricane Harvey allowed some homeowners to rebuild without having to meet costly elevation requirements, City Manager Morad Kabiri said. The map change only affected the Harris County side of the city.
Kabiri said if any homeowners in the area affected by the map change would be grandfathered, meaning they would not be required to elevate if the new map standards would have required it.
"Staff's recommendation ... is to adopt the latest and greatest maps for the city of Friendswood," Kabiri said. This includes a preliminary 2018 Galveston County map, a preliminary 2017 Harris County map and a 2007 Harris County map for a small portion left out of the 2017 revision.
The new maps would only be used for new building permits as well as significant repair permits after future storms, Kabiri said.
However, the 1999 maps are currently still in use by the Federal Emergency Management Agency to determine flood insurance rates and requirements.
"I strongly encourage folks get flood insurance regardless of what flood zone they are in," Kabiri said.
Council Member Robert Griffon cautioned that the map change will mean some developers may be affected with more strict requirements.
"We need to make it clear too, that there's going to be more people in the A&E [flood zone], and they're going to have to mitigate," Griffon said. "We think we're doing something really great, but we're going to hear the negative side of it, too."
The council also approved hiring a Rice University research team to conduct a flood study to provide data to the city's drainage subcommittee. A report from that team is expected by January.
