Residents who live within 200 feet of the planned Walmart in Cibolo filed a lawsuit this week to try to prevent the chain store from breaking ground.
The lawsuit was filed in Guadalupe County Monday.
It alleges Cibolo officials did not property notify residents about the proposed zoning change.
It also said the C-3 zoning is not appropriate for the proposed use.
The lawsuit is asking the court to declare the rezoning null and void.
It was not clear late Thursday when a judge would hear the matter.
Cibolo council members approved the zoning in late September.
The site selected by Walmart is located across from Wiederstein Elementary School and the Bentwood Ranch subdivision, and near the Falcon Ridge subdivision and Everyday Fellowship Christian Church on North Main Street.
Residents of the Bentwood Ranch and Falcon Ridge subdivisions oppose the store's proposed location because of concerns over traffic safety, its proximity to a school, and fear of increased crime in their neighborhoods.
