Glenwood Springs City Council will receive an update tonight on the progress of the tennis bubble.The bubble, purchased by the city earlier this year for $8,000, would provide tennis players with a place to play their sport in winter. According to Parks and Recreation Department director Dan Rodgerson, a faction of tennis advocates has approached his department, inquiring if it would make more sense to build six courts with no cover, or build four courts, two under the cover. Also, Rodgerson said the department has encountered trouble in obtaining surface materials for the courts, which could delay their construction. He said he plans to explain all new developments to City Council tonight.Also on tonight’s agenda:-Council will consider whether to ink a wind-power purchase agreement with the Municipal Energy Association of Nebraska.-Council will consider an ordinance prohibiting the carrying of weapons in city parks. The ordinance is being pushed so Glenwood Springs police have a law to prosecute those who misuse firearms in South Canyon. Much of the land there is classified as city parkland. “We haven’t had a lot of major problems,” Glenwood Springs police chief Terry Wilson said, calling it “more of a housekeeping ordinance.”-Council will consider a proposed jail contract with Garfield County. The contract would allow the detention of municipal prisoners. It would cost Glenwood Springs – or any other city in Garfield County – $15 per day/per prisoner. The city also must give prior approval for any nonemergency medical services. Tonight’s meeting starts at 6:30 p.m. at Glenwood Springs City Hall, 101 W. 8th St.
