II. Background

The City of Calabasas is located in western Los Angeles County in the foothills of the Santa Monica

Mountains and adjacent to the San Fernando Valley. Situated approximately 25 miles west of downtown

Los Angeles and eight miles east of the Ventura County line, the City has a population of approximately

23,000 people. The City spans an area of approximately 13.75 square miles and is bordered by the cities of Hidden Hills to the north, Agoura Hills to the west, Los Angeles to the east, and unincorporated

Los Angeles County to the south.

Primary access to the City is from the Ventura Freeway (Highway 101) or by Malibu Canyon Road from

Pacific Coast Highway (PCH, State Route 1). Mulholland Highway provides secondary access between PCH and the Ventura Freeway, while also connecting the eastern and western portions of the

City through unincorporated Los Angeles County lands to the south.

The City of Calabasas was incorporated in 1991. However, the first occupation in the area was by

Chumash Native Americans who settled along the banks of Calabasas Creek. The Chumash were contacted by the Spanish during the mid-1700s. The City’s distinctive character is in part derived from its history, natural environment, oak-studded hillsides, and sprawling open space. Other notable characteristics include its topographical diversity, small town atmosphere, and active population. Old

Town Calabasas represents the historical heart of Calabasas. Developed as a combination of both the old west and modern-day styles, it features a mix of retail shops, fine restaurants, and the historic

Leonis Adobe, one of the oldest buildings in the Los Angeles area.

Calabasas is primarily a residential community and is recognized as one of the most desirable places in the region to live. The community is distinguished by its geographical setting, privacy, city and neighborhood events, excellent public schools, and high-quality public services.
