Casey Shorrock focuses her legal practice on environmental and land use law, specializing in CEQA, NEPA, natural resource management, and entitlements. Casey works seamlessly with both public and private entities to help projects progress responsibly and timely through permitting processes, meet the goals of involved parties, and assist clients if legal or other challenges arise. Her transition from a successful former career in environmental consulting and planning to the legal field uniquely positions her as a seasoned advisor for clients navigating complex environmental and regulatory challenges.
Drawing on her extensive background, Casey offers a holistic perspective, integrating legal strategies with practical insights from years of hands-on experience as an environmental consultant and planner. By leveraging her deep understanding of environmental regulations and ability to identify technical and legal nuances, she provides clients with tailored solutions that meet regulatory requirements and effectively address real-world environmental concerns. She handles litigation and pre-litigation matters involving environmental and land use law, with emphasis on CEQA, NEPA, natural resources, endangered species and wetlands, water resources, air quality, climate change, solid waste, wildfire prevention regulation, and state housing and development regulations, and local environmental and land use ordinances.
In her previous career, Casey worked with and for agencies at all levels of government, she managed the environmental review process for a variety of successful development and infrastructure projects and government actions, including preparation of state, federal, tribal, and joint environmental documents, focusing on approvals, permitting, and streamlining environmental regulatory compliance. Casey brings these same skills to her legal practice.
Casey attended McGeorge School of Law on a full merit scholarship as an Anthony M. Kennedy Fellow. During law school, she worked as a summer associate for Remy Moose Manley, LLP, and externed for Judge Kimberley J. Mueller at the U.S. District Court for the Eastern District of California. At McGeorge, she received the Stauffer Charitable Trust Research Fellow Award for her paper Environmentally Responsible and Streamlined Development in California: The Promise of CEQA’s Class 32 Exemption and Witkin Awards for academic excellence in Environmental Law and Oceans & Coastal Law. Prior to joining Somach Simmons & Dunn, Casey worked for Remy Moose Manley.
As a fifth generation Sacramentan from a large Irish-American family, Casey has deep roots in the community, which helps bring an important local perspective to all of her work. She also brings a broader perspective, stemming in part from her extensive national and international travels and time living and working abroad in China. Outside of work, Casey enjoys time with her family—gardening, skiing in Tahoe, managing two rambunctious pugs, going to music shows with her daughter, and visiting Disneyland as often as possible.
