SIOUX FALLS, S.D. (AP) — City officials in Sioux Falls say building activity reached a new all-time high in 2015, with $676.3 million in construction permits issued.

Finance Director Tracy Turbak says the strong building activity contributed to a 5.9 percent growth in city sales taxes and an unemployment rate of 2.6 percent.

Turbak presented the preliminary 2015 year-end financial results to the Sioux Falls City Council on Tuesday.

He says the city used a small portion of its reserves for the first time in five years. It budgeted for the use $5.3 million in operating reserves but wound up using only $2.5 million.

Turbak says the use of reserves allowed the city to open its 11th fire station and complete some needed building maintenance and renovations.
