There goes the neighborhood—in the best way possible. April brings the opening of Estación Federal, a mixed-use compound housed in an abandoned 1950s structure that includes a café, deli, shipping container art gallery, craft brewery, a courtyard that hosts a monthly farmers’ market, and a cluster of office spaces and apartments whose monthly rents average $500—all within a 10-minute walk from the San Ysidro pedestrian border crossing.
