To meet the solar energy requirements, buildings in the new business district were constructed with heavy insulation and earth-berming to supply thermal mass. South facing roof slopes and windows were built to capture maximum sunlight, and blowers and hydronic systems were installed to circulate the collected heat. Over twenty solar heated businesses were eventually built in the small community. While federal funds had been allocated to help relocate businesses from the floodplain, no additional federal monies were provided for the solar heating initiative.
