Manville on L.A.’s Spot Street Widening Regulations
Michael Manville, professor and chair of UCLA Luskin Urban Planning, is cited in a Los Angeles Times editorial on the city’s longstanding street-widening requirements, so-called “zombie regulations” that are now getting the attention of local lawmakers. Under these regulations, in place since the early 1960s, new apartment and commercial developments are often required to dedicate part of the property to the city for road expansion. Road expansions account for L.A.’s “jigsaw-puzzle” configuration of widening and narrowing streets, according to the editorial. While intended to improve traffic flow, whether roads are congested or not, the editorial argues that the parcel-by-parcel widenings provide little or no congestion relief while they take out mature trees, parkways and sidewalk space. “I’ve studied urban regulations for 20 years, and this is probably the dumbest regulation I’ve ever encountered,” Manville said. The editorial also cites research by Manville showing that the road widening regulation increases the cost of housing.
