An opponent of the Siesta Promenade development has sued Sarasota County, asking a judge to “quash and remand” the county commission’s December decision approving the project.

Sura Kochman, who led protests against the development plan, is challenging the legality of the board’s decision.

In the suit, Kochman claims she and her neighbors in Pine Shores Estates will be “adversely affected by increased traffic, increased height, increased density and increased intensity.”
