Scott Condon/The Aspen Times The midvalley is experiencing a construction boom this year that will result in a population surge down the road. There are 11 major projects for residential, commercial or mixed uses that are under construction, soon to get underway or in the planning process, according to an assessment of records by The Aspen Times. More projects are poised to enter the pipeline.
