Oakland Mayor Libby Schaaf readily acknowledges that Measure KK’s $600 million bond represents a substantial investment in repairing and maintaining the city’s streets and sidewalks, community facilities and affordable housing options.

“Big is what we need,” she told our editorial board.

The largest chunk of the bond money, $350 million, would go toward streets and sidewalks. Residents and anyone else who has spent any time in the East Bay city would acknowledge the need: only 25 percent of its streets are considered in good repair. Measure KK funding would allow the city to raise that level to 70 percent.

As Schaaf reminded, deteriorated roads carry a hidden cost for motorists from blown tires, wheels thrown out of alignment and — not least of all — additional accidents. “If you don’t pay with KK, you pay at the auto shop,” she said.

City-owned facilities such as libraries, parks, recreational facilities and police buildings would account for $150 million of the bond proceeds. Those projects would include seismic and green-energy upgrades — investments that should save the city costs in its annual operating budget.

The $100 million toward housing includes some innovative ideas to prevent displacement. The bond money would be used to acquire and renovate rental housing in serious need of repair. Once those improvements are completed, the units would become locked in at below-market rates for low-income residents. This program would allow the city to leverage state and federal funding sources aimed at affordable housing.

Measure KK, which requires a two-thirds vote for passage, would add about $60 to the annual property tax bill of a home assessed at $250,000, the median in Oakland.

One of the appealing elements of Measure KK is that it is focused on the practical. It does not include any shiny new projects.

“This is a fix-it first measure,” Schaaf said.

Vote yes on Measure KK.
