The city of McKinney is facing challenges with its efforts to close two concrete batch plants as a lawsuit from one of the plant’s owners claims the city’s methods are illegal.
In the summer of 2020, the McKinney Board of Adjustments agreed that one of the plants, Martin Marietta Materials Inc., had until April 29, 2021, either to close or to come into compliance with the zoning ordinance for that area. In September 2020, the board approved a compliance date of Aug. 26, 2027, for the CowTown Redi-Mix plant.
The two plants, CowTown Redi-Mix and Martin Marietta produce ready-mix concrete and operate on about 10 acres along SH 5, also known as McDonald Street.
The city has been trying to close the plants and said in court documents that it is doing so legally. The process—known as amortization—began earlier in 2020 with the identification of land uses that are not allowed under the current zoning, after which landowners are given a certain amount of time to shut down.
