Building Los Angeles doesn't often trek north of the Santa Monica Mountains, but a renewed focus on urban communities in the San Fernando Valley has started to change this.  A variety of mixed-use developments are currently in the pipeline, concentrated in walkable hubs in Glendale, North Hollywood and Warner Center.  One of the newest players in the arena is a project anointed as Sepulveda Square.  Plans call for 131 apartments and just over 8,000 square feet of ground floor retail space, encased within a five-story structure north of the intersection of Sepulveda and Burbank Boulevards.  The building would feature a two-floor parking garage with room for 274 automobiles and 154 bikes, with one level situated below grade.  Residents can feel free to leave their cars behind, with the Sepulveda Dam Recreation Area and an Orange Line busway station both just a hop skip away.  If Sepulveda Square residents really want to drive, they can always brave the ever-crowded 405 one block to the west.
