With the economy humming along, innovative ideas sprouting up around the state, and, of course, the occasional dispute, 2015 was as lively a year for land use as any other in recent memory. To mark the new year, CP&DR presents its most-read stories of 2015. 

It turns out that two of the world's biggest proponents of smart growth are Catholic. One of them is California Governor Jerry Brown, who once studied to be a Jesuit priest and, more recently, has promoted earthly initiatives like high-speed rail, the adoption of vehicle miles traveled metrics, and the most ambitious greenhouse gas reduction goals in the western hemisphere. 

The other is the Pope. 

Back in 2010, when I was Mayor of Ventura, the city installed parking meters downtown for the first time in 40 years. Not for every parking space, of course. The meters covered only 300 or so prime spaces on Main Street and a few popular side streets. Thousands of other downtown spaces � both onstreet and off � remained free.

 The problem we were trying to solve was a pretty typical one: Demand was so high for the prime spaces that people were cruising up and down Main Street, causing a constant traffic jam, in search of a space. The spaces themselves were hogged by merchants and their employees. It was hard to enforce the existing two-hour time limit, and the parkers gamed the system with such familiar tricks as wiping the meter maids' chalk of their tires. Meanwhile, a half-block away, parking lots and a parking garage sat empty.

The vast majority of California jurisdictions are now addressing greenhouse gas emissions, and increasingly they are using reduced parking requirements to achieve the "smart growth" land use changes that go along with emissions reductions.
