Urban golf courses are making housing more expensive and parks harder to access — and taxpayers are footing the bill

• Urban golf courses are used by a fraction of city residents, but take up a ton of space and resources. 
• Many states subsidize golf courses with low property taxes, so non-golfers are footing the bill. 
• Urban planners want to redevelop some courses into public green space and housing.

San Francisco's 18-hole Presidio Golf Course sits in some of the most prized land in the country: a national park.
