It’s relatively easy to point to the 1973 opening of the Walnut Creek Bart Station as one of the most significant events that shaped the city’s future. Other than the emergence of Broadway Plaza as a regional shopping destination, it was BART that connected Walnut Creek to cities across the Bay, and brought with it a new work force, a new tourism class, and a new interest in business development.

A building boom soon followed in 1975, targeting the areas surrounding BART for major office development and sparring debates about the politics of growth. City leaders responded with a core area plan establishing employment centers closer to home and reducing travel time for commuters. A decade later, the twin ten-story Tishman Office Center and California Plaza buildings opened, forming the so-called “Golden Triangle” for its potential as the financial hub of the East Bay. In 1985, Walnut Creek voters passed Measure A restricting height limits and preventing tall buildings from popping up all over town. Now 36 years later, NOMA, a new multi-use apartment complex under construction on the former Main Street Fuddrucker's site, will exceed Measure A height limits for the first time in the city’s history.
