Developers in certain downtown neighborhoods will be required to give more to the arts following voter approval of Proposition X on Tuesday.

Prop. X, which only impacts developments in the Mission and parts of South of Market, requires developers to replace arts, community and light industrial and repairs operations that their projects impact.

Specifically, the measure calls for the replacement of any light industrial operations that use 5,000 square feet or more; community uses, such as day care, of 2,500 square feet or more; or arts activities of any size.

Exceptions to the measure are projects approved before June 14, 2016; and projects that offer 100 percent affordable housing units.

Proponents had said the measure was needed to prevent developers from eliminating such properties from an area, while those opposed countered the measure was not the solution to the needed up-zoning of the area.
