Municipal Settings Designation

MSDs prohibit the use of impaired shallow groundwater as potable water. In the City's ordinance, potable water is defined as, water that is used for irrigation, production of food or drink products intended for human consumption, drinking, showering, bathing or cooking purposes. An MSD does not remove any liability from the property owner, nor does it shift any liability to the City.

History:

In 2003, the Texas Legislature authorized the creation of MSDs, which would designate an area in which the use of contaminated groundwater is prohibited from use as potable water. The law is administered by TCEQ. The intent of the legislation is to encourage redevelopment of vacant or abandoned properties while protecting the public health.

On August 22, 2007, City Council approved an Ordinance amending Chapter 47 of the Code of Ordinances by adding Article XIII relating to groundwater, which will provide a process for supporting or not supporting a Municipal Setting Designation (MSD) application to the State. The City's program became effective November 1, 2007.
