There are also preservation advocates who have been campaigning to prevent a relocation of City Hall functions from 1500 Marilla St. The Save Dallas City Hall Coalition is aligning with the group. Katherine Seale, former executive director of Preservation Dallas, told CandysDirt.com that Save Dallas City Hall’s involvement makes for a natural coalition. If the city secretary certifies the petition, the city council must call an election on the next available election date allowed under state law. The full city council will take a vote on the Melshire Estates case on August 12 and the Walnut Hill/Marsh application on August 25.
