To make a city a more desirable place to live, to generate tax revenues, to capitalize on advertising dollars, to help secure employment for city residents, to help draw visitors to the city, to have facilities which allow them to draw bigger acclaim (the Olympics), to provide a site to smaller groups that could not otherwise play at such a facility (small colleges, High school champioships etc.), to attract businesses (restaurants, hotels) to an otherwise less then desirable neighborhood.
