Prominent Land Use Lawyer Frank Petrilli Joins Coblentz Patch Duffy & Bass

San Francisco-based law firm Coblentz Patch Duffy & Bass LLP is pleased to welcome Frank Petrilli to the firm’s partnership. Frank joins Coblentz from Arent Fox.

Frank Petrilli is a trusted advisor to his clients on all matters related to entitlement strategy, land use and land use litigation, and compliance under the California Environmental Quality Act (CEQA). His recent projects include advising on Facebook’s headquarters expansion in Menlo Park, as well as working closely with Facebook’s public policy team in connection with its $1 billion housing investment in California; advising Kylli in connection with the Burlingame Point office campus project; as well as advising on a number of prominent multifamily, mixed-use, hospitality, office and life science projects throughout the Bay Area.

“We’re thrilled to welcome Frank to Coblentz,” said Matt Bove, partner and chair of Coblentz’s real estate and land use practice. “His geographic focus on the Mid-Peninsula, Silicon Valley and Santa Cruz enhances our team’s existing depth and breadth of expertise in these areas, and his particular experience with complex entitlement matters makes him a great addition to our deep bench of top-notch land use attorneys.”

Frank serves on the Board of Directors of the San Mateo County Economic Development Association (SAMCEDA) and the Bay Area Council. In 2020, he was named among the “Top 40 Under 40” attorneys in California by the Daily Journal and is a Legal 500 recommended Land Use & Zoning attorney (2017-2020), as well as a “Northern California Rising Star” by Super Lawyers every year since 2016.

“I was attracted to Coblentz by the depth and quality of the land use practice, as well as the firm’s collaborative culture, its values, and, of course, its people. My clients will undoubtedly benefit from having access to such a talented and committed team of lawyers,” said Frank Petrilli. “I am thrilled and privileged to join what I truly believe is the strongest real estate and land use practice in California.”

Coblentz’s real estate and land use practice has guided some of the largest commercial and residential development projects and transactions in California. These projects vary from major sports arenas including the San Francisco Giants’ Oracle® Park, San Francisco 49ers’ Levi’s® Stadium and the LA Clippers’ arena in Inglewood to major neighborhood-transforming projects such as the $1 billion 5M Project (one of the largest mixed-use projects in San Francisco), Catellus Development Corporation’s 300-acre Mission Bay project, redevelopment of the Vallco shopping mall in Cupertino (the first mixed-use, mixed-income project in the state to successfully use SB 35), and the 154-acre Napa Pipe residential redevelopment project in Napa County. Also included among our notable representations are renowned cultural institutions such as the California Academy of Sciences and the Exploratorium, world-class health care campuses including Sutter Health/California Pacific Medical Center hospital rebuilding projects in San Francisco and John Muir Health facilities throughout the East Bay, and the largest land use and conservation project in California history at Tejon Ranch. The Coblentz Real Estate and Land Use group is top ranked in Chambers USA and Legal 500 USA, and our attorneys and projects are continuously awarded by The Best Lawyers in America, The Daily Journal, and the San Francisco Business Times, among others.
