Round Rock City Council approved repairs to the Dell Diamond Nov. 12 as part of a five-year plan for maintaining the stadium. According to the plan, the facility will receive $1 million worth of improvements in the 2015-16 baseball off-season, including seal coating and re-striping the parking lot to prevent deterioration, converting parking lot lights to LEDs and installing a new sound system. Tim Jackson, community relations manager with the Round Rock Express, said Nov. 10 at a council workshop that the current sound system is original, and its volume levels can be erratic. "[The sound levels are] reasonable, then spike, then go back down," Jackson said. "Twenty percent of our speakers are dead. That's the state of our sound system at the moment." Further improvements in the plan include replacing the fire sprinkler system in 2016-17 off-season at a cost of $200,000, replacing field lights and general lights with LEDS at a cost of $840,000, and a full replacement of the stadium seatings in 2018-19 at a cost of $1.2 million. The parking lot will see further improvements and repairs in 2019-20, under the plan. The plan will be updated annually, according to city staff. The funds for the improvements will come out of the city's Hotel Occupancy Tax funds. The city of Round Rock owns the Dell Diamond and leases it to Ryan-Sanders Baseball, owner of the Round Rock Express. Round Rock Chief Financial Officer Susan Morgan said Ryan-Sanders baseball will also invest about $750,000 in the stadium in the coming winter season. According to city documents, since the stadium was built the city has invested $3.4 million in stadium improvements, and Ryan-Sanders baseball has invested about $7 million in stadium improvements. "We’ve been through 16 seasons with this facility and have invested a lot in it, but they have done more," Morgan said.
