The St. Louis Post-Dispatch reports the project faces opposition from residents of Frontenac worried about its effects on traffic.
The lawsuit in St. Louis County Circuit Court alleges that the St. Louis County Library District “refuses to engage in meaningful discussion” about appropriate use of the project site. Attorneys for Frontenac filed the lawsuit Wednesday.
The library district is a political subdivision of the state. Its board can overrule the city with the votes of four of the five trustees.
Library district trustees voted 5-0 last month to approve the project, two days after Frontenac’s zoning board rejected it.
