State lawmakers have introduced an extraordinarily diverse collection of bills regarding land use planning, natural resources and infrastructure this year. While lawmakers' interest in affordable housing and redevelopment reform appears to have waned, the number of bills related to climate change or renewable energy has increased dramatically in 2009.

Legislators have proposed at least five measures that would place water bonds before voters. Other measures are aimed at enhancing the health and changing the governance of the Sacramento-San Joaquin River Delta. Bills concerned with development in fire-prone areas have returned after failing last year, as has a measure to ease use of tax increment financing for infrastructure around transit stations. There is also a bill that would raise vehicle license fees to fund at least some of the regional planning required by last year's SB 375.
