Despite delays caused by frigid winter weather, Keller district officials expect the addition at Timber Creek High School to be ready for classes in August.“Extreme temperatures and weather did slow down construction over the last several months. We anticipate activities to pick up and be on schedule in the next three or four weeks,” said Hudson Huff, director of construction and planning.Crews are working on a 30-classroom wing to deal with fast-growing enrollment. Timber Creek opened in 2009 with capacity for about 2,500 students. Last week, enrollment was at about 2,760, making Timber Creek the largest of the four KISD high schools. Keller High is second with about 2,600. Several portable classrooms are on site to deal with the overflow.In January 2013, Keller school board members approved $9 million for the new wing, adding a parking lot on the northwest side of campus that would serve as a marching band practice area, improved baseball and softball practice facilities and additional parking next to the tennis courts.Huff said that work was complete on the parking areas and practice facilities. Crews have also finished connecting Funnel Street to the east with the circular road around the perimeter of campus. The new road opened a little over a month ago, providing drivers another access point to and from Alta Vista Road.All projects should be completed (including furnishings, fees and equipment) within the $9 million budgeted from the 2008 bond package, Huff said.The classroom addition will give Timber Creek a capacity of 3,000. According to demographic projections from consultant Bob Templeton, the school should continue to be the fastest growing high school and surpass 3,000 by 2015-16.District officials are looking at a possible career and technical education center to reduce crowding at Timber Creek and the other high schools. If approved by voters in November, the earliest the facility could open would be fall 2016.
