In the continuous scrum of Los Angeles County planning, some kind of milestone was reached this spring when the Board of Supervisors formally approved the county's 2035 General Plan update.

The new document is the first comprehensive rewrite of county planning rules since 1980. Among other things, it represents a new focus on the county's urbanized unincorporated areas, as well as more traditional undeveloped areas on the fringe. It is the first L.A. County general plan to take advantage of digital mapping approaches in promoting more consistent groupings of land use policies across multiple properties and types of ownership. It's an approach that meshes well with current state and federal planning processes for alternative energy -- which matters especially because of pressures for solar and wind energy development in the Antelope Valley.

By most accounts, planners don't need to pay much mind to the policies of stage actors unions. It's the rare city in which theaters have much of an impact on the built environment. And yet, planners have every reason to care about the culture of the cities that they build and administer, and cities can profit mightily from their theater scenes — especially when the the city in question is Los Angeles. 

That's why everyone in Los Angeles, actor and non-actor alike, should care about the recent vote by the leadership of Actors Equity. Actors Equity is the guild to which most professional and aspiring stage actors belong. After a bitter dispute over questions of professionalism and exploitation, the 100 members of the guild's National Council voted to require union actors to accept no less than $9 per hour to work on professional stage productions. Formerly, actors could essentially volunteer to perform in "equity waiver" productions, which were limited to theaters of fewer than 100 seats. This opportunity goes away June 1, 2016.

Until the mid-2000s, the South Park neighborhood of downtown Los Angeles had exactly one high-rise tower: the looming, vaguely Stalinist Transamerica Building (now the AT&T Center). It most famously supplied the rooftop where Guns 'n Roses shot the video for "Don't Cry." The area—which occupies the southern portion of downtown Los Angeles, between the Financial District and Interstate 10—otherwise consisted of dilapidated retail, low-rent residential buildings and acres of surface parking lots. 

The area was avoided by businesses, developers, and rock stars alike. 

Today, the AT&T Center is but the tallest tree in a rapidly growing forest. No fewer than 20 high-rise and medium-rise projects are under construction or in development in the roughly 40 square-block area. At least that many projects are in earlier stages of development. 

It is, say planners, the next phase in the resurgence of downtown Los Angeles. 

Currently on display at the Annenberg Space for Photography in Los Angeles, Sink or Swim: Designing for a Sea Change is an arresting exhibition depicting consequences of, and solutions to, rising sea levels. It includes photographs by artists and journalists of disasters, like Hurricane Katrina and the Japanese tsunami, and responses, like floating schools in Bangladesh, sculpted sea walls in the Netherlands, and the restoration of the Malibu Lagoon, just a few miles away. Sink or Swim celebrates, and issues a charge to engineers, designers, and public officials to acknowledge rising seas and start embracing ways to build resiliency.

Sink or Swim was curated by Frances Anderton, known locally for hosting KCRW public radio's DnA: Design & Architecture show. She spoke with CP&DR's Josh Stephens.
