TGR Board Approves Redistricting Plan
Illustrative Plan 1.jpg

The map depicts the proposed changes to the TGR precinct boundaries. The red line shows existing boundaries.

The Trinity Glen Rose Groundwater Conservation District (TGR) Board has officially changed its boundaries to reflect a more consistent population base in each precinct. Redistricting is part of the election process in the United States. And because the TGR board members are elected, the district recently reviewed its population changes over the past 10-year period and found it needed to adjust its boundaries due to population shifts in the precincts. The objective is to balance the per capita representation for each precinct in order to give all district constituents an equal say via their elected representatives regarding district policies and future directions. The TGR Board used the following criteria to make its final boundary adjustments:


  • begin and end with identifiable boundaries

  • maintain communities of interest & neighborhoods

  • use whole voting precincts if possible

  • base plan on existing districts

  • adopt districts of relatively equal size

  • draw districts that are compact and contiguous

  • keep existing incumbents in their districts to preserve previous voter wishes

  • tailor plan to comply with the Voting Rights Act

Before making a final decision on its redistricting plan, the Board opened its planning documents up for public review and comment. At the Dec. 9 board meeting, the Board held a public hearing to receive any final comments before taking official actions to change the TGR precinct boundaries.

After a thorough planning process and public comment period, the TGR Board officially changed its boundaries to ensure a balanced population base in each precinct. The results can be seen in the chart below which shows the precinct population disparity at less than 10%, which is the accepted standard. These new boundaries will remain in place until the next U.S. census reports are received.

Due to the change in boundaries, the district will be holding an election to fill all precinct seats in May, 2022. Click here for more information.

Don't Wait to Winterize Your Home

Winterizing plumbing pipes is a process that prepares household plumbing for freezing temperatures that can cause leaks and breaks in the home. When water freezes, it expands as it becomes ice. This expansion produces pressure within pipes, which causes damage. You should identify the pipes most vulnerable to freezing. Look for pipes located on outside walls, uninsulated pipes, and pipes installed near unheated spaces. You can insulate the pipes with insulation sleeves or by wrapping them with slip-on foam pipe insulation. Do not leave any gaps without insulation as cold air can affect the pipe in these spaces. Plastic piping is more tolerant of freezing than old copper or steel water pipes. Here are a few more tips to follow to keep your home safe from broken water pipes due to freezing weather.

  • Keep garage doors closed if there are water supply lines in the garage.

  • Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing.

  • Consult your water company about letting water drip from exposed water pipes.

  • If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55 degrees F.

Time to Have your Sprinkler System Checked
$50 Coupon for irrigation consult v2-2.j

July through September is typically the hottest and driest stretch of weather we see in South Texas each year. Any by now you know that means that your water conservation knowledge and skills should be on high alert. Because landscape watering can account for up to 60 percent of the city’s water use during this time of year, the Trinity Glen Rose District always like to remind homeowners and business owners to have their sprinkler systems inspected before the systems are turned on for regular use. Wasted water cannot be retrieved, so you only get one chance to efficiently use the water provided by the city’s water resources such as the Trinity and Edwards Aquifers.

The quickest do-it-yourself way to check your system is to start it up and then inspect each of the sprinkler heads in all of the system’s zones. Look for broken heads or heads that have sunken below ground. Then make sure that the heads are not watering the streets and sidewalks. Then you can observe whether there is adequate water pressure feeding each sprinkler head. A broken pipe or sprinkler head can drain away pressure and waste significant amounts of water.

Also, if you have been slowly and steadily replacing high water use plants with native low water use plants, you might make sure that your sprinkler system either does not water areas with native plants or waters only a little.

Here is some great news for you. The Trinity Glen Rose District and San Antonio Water System have teamed up over the last few years to offer free irrigation system consultation programs. In fact, TGR will give you a $50 coupon to have the consultation done. Just go to for more information.

TGR Publishes 2020 Annual Report 
2020 Annual Report front page.png

The Trinity Glen Rose Groundwater Conservation District (TGR) just published its 2020 Annual Report. The TGR board reviewed the report in early March and approved the document for publication at its March meeting.

The 2020 Annual Report provides good background on the:

  •  purpose of the district

  •  district goals

  •  current leadership

  •  well monitoring work

  •  financial position, and

  •  community outreach programs

This year, the District included two charts which outline TGR’s involvement in regional GMA-9 joint water planning efforts required by the State of Texas. The charts provide a 10-year history of water use in the region and how that compares to the region’s goals for water production from the Trinity Aquifer. Those goals are known as “desired future conditions.”
