BERTHOUD — Two new commercial developments will soon begin to generate sales-tax revenue for the town of Berthoud based upon recent approval of development plans. The developments include nearly 30 acres of commercial space, and one of them also includes 7.3 acres of residential space. First out of the chute will likely be what is now called Heron Lakes Commons, a 16-acre development at the entryway to the TPC Colorado golf course at Heron Lakes. The development is on the northwest corner of the intersection of Berthoud Parkway (Taft Avenue in Loveland) and U.S. Highway 287. The site has received master-plan approval from the town of Berthoud, according to town administrator Chris Kirk.
