One of the sleepier sections of Wilshire Boulevcard may become a little less so, as development begins spreading east from the Miracle Mile and west from Koreatown.  The surface parking lot at the southeast corner of Wilshire and Crenshaw Boulevard is slated for a 30-unit apartment building.  Residential units would rise within a four-story structure, served by a 67-vehicle parking garage.  Construction equipment will also be on site at a neighboring parcel over the next several years, albeit for a very different type of project.  According to Larchmont Buzz, Metro will utilize the parking lot at the southwest corner of the intersection as a construction staging yard for the first phase of the Purple Line extension.  A little bit of traffic and noise pollution now in exchange for Los Angeles' most important transit project in decades.  Unfortunately, a proposed station at Wilshire and Crenshaw was nixed from the project years ago due to low ridership potential.  Of course, that's not much of a surprise considering that Hancock Park's zoning mandates such a low density project at a high profile intersection.
