The Allen R. Baca Center for Senior and Community Activities celebrated 20 years of serving the greater Round Rock community in April. 

In a nutshell: The center first opened in March 2006, as one of the first city-owned senior centers in the area. At the time, it was also one of the largest at 29,000 square feet. 

It is named for Allen R. Baca, who worked with the city to open the city's original Round Rock Senior Activity Center on Main Street in 1993. 

Did you know?: The facility offers rentable exercise spaces, meeting spaces and an arts and crafts room.

Area seniors can participate in a variety of interest clubs for gardening, art, book discussion, woodworking, writing, crafting, dancing and many other activities coordinated through the center. 

Additionally, the center offers athletics programs for seniors, a gym, personal training, benefits counseling through the Area Agency on Aging as well as meals through the Opportunities for Williamson & Burnet Counties Senior Nutrition Program for those 60 years of age and older. 

The city of Round Rock held grand openings for new recreation facilities in April. 

What you need to know: The new Joanne Land Playground, tennis and pickleball courts in Old Settlers Park are now open, with the city having held celebrations to present these new facilities to the community April 25. 

The $1.8 million project is funded through a 2023 voter-approved bond. WeBuildFun, which installed the original Joanne Land Playground in 2016, is installing the new version. The tennis and pickleball complex, which opened to the public in March, cost $17 million to build. It was also funded through the 2023 voter-approved parks bond. 

The overview: The play structure is twice the size of the original playground and will feature integrated lighting to allow for visitors after dark. It also includes rubber surfacing and plastic components designed to minimize heat absorption, according to the city.

On May 26, Texas Republican voters will choose their nominee for the U.S. Senate in a runoff election between incumbent Sen. John Cornyn and state Attorney General Ken Paxton.

The big picture: The Republican race for U.S. Senate is one of several statewide contests that advanced to May runoffs after no candidate received more than 50% of the vote in the March 3 primary election.

Cornyn and Paxton were the two highest-performing candidates in the eight-way primary race, with Cornyn securing 42% of the vote to Paxton's 41%.

At the polls: Early voting in Texas' runoff elections runs from May 18-22, and runoff election day is May 26.

Looking ahead: The winner of the May 26 overtime round will face the Democratic nominee for U.S. Senate—state Rep. James Talarico of Austin—in the November midterm election. Third-party and independent candidates may also appear on the November ballot, and the winner of that election will be sworn in to the U.S. Senate in January 2027.
