SAN FRANCISCO—Mayor Edwin Lee joined executives from Kilroy Realty Corporation and salesforce.com yesterday in breaking ground on San Francisco's first new LEED Platinum tower at 350 Mission Street. Kilroy Realty's sleek glass and concrete office tower will be located at the corner of Mission and Fremont Streets, immediately across the street from the city's new Transbay Transit Center and Millennium Tower.

The office tower, which has been 100% pre-leased to enterprise cloud-computing leader salesforce.com since the project was first announced last fall, represents another milestone in the revitalization of the Mission Street corridor—now a magnet for the city's burgeoning technology and media businesses. During the groundbreaking ceremony for the new tower, Mayor Lee said, “The construction of 350 Mission Street affirms the investor confidence in our City, and I am pleased to partner with salesforce.com and Kilroy Realty on this exciting venture to help deliver on a vision for the Transbay district where people can live, work and play sustainably with rich access to regional transportation.” Salesforce.com COO George Hu followed the Mayor by saying, “The 350 Mission office tower will be an incredible addition to salesforce.com's expanding downtown San Francisco campus. We are proud to have our global headquarters in San Francisco and we are committed to continuing to grow and add jobs in the City.”

The new office tower's design incorporates many state-of-the-art sustainability practices, including use of recycled materials and leading edge energy efficiency technologies.
