HB2146: Rules on Turf and Plant Lists for Some Cities

This law stops cities in initial active management areas from requiring minimum amounts of grass or banning plants not on the state's low-water list, while also keeping mesquite off that official plant list.

What This Bill Does

  • Stops municipalities in initial active management areas from creating rules that require a minimum amount of turf on properties.
  • Allows exceptions for functional turf used in public spaces like playgrounds, sports fields, cemeteries, schoolyards, and stormwater management, but excludes stormwater drainage areas located in subdivisions.
  • Prevents cities from requiring the installation of plants not found on the state's low-water-use and drought-tolerant plant list published by the department for current management plans.
  • Prohibits the department from listing any species of mesquite as a low water use or drought tolerant plant.

Who It Names or Affects

  • Municipalities located in initial active management areas
  • The state agency that publishes the low-water-use and drought-tolerant plant list

Terms To Know

Initial Active Management Area
A specific geographic area where groundwater use is managed under a current management plan.

  • The text provided does not state when this law will officially take effect after passing the legislature.
