McVILLE (AP) - North Dakota cities and towns are facing aging infrastructure problems and housing shortages as the state's economy grows.

"Those seem to be the common themes," said Connie Sprynczynatyk, executive director of the North Dakota League of Cities.

Infrastructure problems include everything from water and sewer systems to roads.

"Transportation funding is going to be a major issue in the next session of the state Legislature," Sprynczynatyk said.

Hillsboro Mayor Kevin Burg said that city's 10 percent share of a N.D. Highway 200 reconstruction project through town has quadrupled since the project was approved last year, partly because of the time required to receive some grant funding.

In northeastern North Dakota, the communities of Park River, Northwood, Fordville, Pembina and Cooperstown all face housing shortages.

Park River is building two four-plex residential buildings. All eight units are rented, and the city has three people on a waiting list.

Northwood is building a new 16-plex apartment building, along with a 14-unit mobile home park, to help replace housing that was lost in the August 2007 tornado that hit the city.

Bowman County, in the southwestern corner of the state, is in need of 150 housing units within the next five years to meet demand, according to a recent countywide assessment that noted increased energy production and a coal-fired power plant that is proposed near Gascoyne.

"There's just so many people that are moving back here. There are the oil people that are from outside the state, but then there is a group of young people that are coming back as well," said Bowman County Economic Development Director Ashley Andrews. "I think people are realizing that Bowman is a growing community, not a dying community."
