City Guide
Del Mar
Where the Turf Meets the Surf
A small coastal city with outsized cultural presence — Del Mar's story from railroad resort to North County landmark
Occupying roughly two square miles of coastal bluffs and canyons between La Jolla and Encinitas, Del Mar is among the smallest incorporated cities in San Diego County. Despite its compact size, the city holds regional significance through the Del Mar Fairgrounds, the Del Mar Thoroughbred Club racetrack, and a fiercely protected residential character that has made it one of Southern California's most recognizable coastal communities.
Indigenous Coastal Stewardship
The bluffs, lagoons, and beaches of Del Mar lie within Kumeyaay ancestral territory. San Dieguito River and Los Peñasquitos Lagoon provided freshwater, gathering sites, and travel routes connecting coastal and inland villages. Kumeyaay ecological knowledge shaped how these landscapes supported seasonal habitation long before the area became a resort destination.
Founding and Resort Development
Colonel Jacob Taylor founds Del Mar as a seaside resort, naming it after the ocean and promoting health tourism along the coast north of San Diego.
The California Southern Railroad reaches Del Mar, linking the resort to national rail networks and accelerating visitor access.
Del Mar Thoroughbred Club opens; Bing Crosby and partners establish the racetrack that would become a signature regional event each summer.
Del Mar incorporates on July 15, enabling local control over land use in the face of regional development pressure.
Early Del Mar attracted Hollywood figures, writers, and vacationers seeking coastal retreat. The racetrack's "Where the Turf Meets the Surf" slogan captured the city's dual appeal of beach recreation and thoroughbred racing.
Twentieth-Century Growth
Incorporation allowed Del Mar to maintain low-density residential zoning and strict height limits that distinguish it from neighboring cities. The Del Mar Fairgrounds — home to the San Diego County Fair and numerous events throughout the year — occupies a significant portion of the city's land area and draws millions of visitors annually.
Postwar development filled canyon rims and bluff-top parcels with custom and semi-custom homes, many designed to preserve ocean views and coastal access. Del Mar's village commercial district along Camino del Mar retained a small-scale, pedestrian-oriented character.
Economy and Employment
Del Mar's economy relies on hospitality, event management, retail, and professional services rather than large-scale industry. The fairgrounds and racetrack employ seasonal and year-round workers and support ancillary businesses in dining, lodging, and event services. The village hosts boutiques, restaurants, and offices serving both residents and visitors.
Many Del Mar residents work in biotechnology, technology, healthcare, and academia in nearby La Jolla, Sorrento Valley, and central San Diego — commuting from a residential base that functions primarily as a coastal enclave rather than a standalone employment center.
Market and Housing Context
The 2020 U.S. Census recorded 3,919 Del Mar residents and approximately 2,000 housing units — one of the smallest housing inventories among incorporated San Diego County cities. Census data reflect a high proportion of owner-occupied units and a housing stock dominated by single-family detached homes on bluff-top and canyon parcels.
Multifamily housing is limited and concentrated near the village and along the coastal corridor. Del Mar's restrictive zoning and coastal location constrain new supply, while existing homes range from mid-century architecture to contemporary custom construction. The city's Housing Element addresses state requirements within the context of severely limited developable land.
The 2020 Census documented a housing stock overwhelmingly composed of detached single-family units on bluff-top and canyon parcels — a pattern consistent with Del Mar's low-density zoning and height limits adopted at incorporation. Condominium and townhome developments represent a smaller share of units, concentrated near Camino del Mar and the coastal zone where the Local Coastal Program permits moderate-density projects subject to design review.
Living in Del Mar
Del Mar offers direct beach access at Del Mar City Beach and Powerhouse Park, coastal bluff trails, and the San Dieguito Lagoon wetland preserve at the city's northern edge. The village provides dining, the Del Mar Plaza, and community events including the Del Mar Farmers Market.
Del Mar Union School District and San Dieguito Union High School District serve local students. The Del Mar Library and community facilities support civic programming in a city where public space is at a premium.

Government and Civic Life
Del Mar operates under a council-manager form of government with an elected mayor and five council members. City policies emphasize environmental protection, traffic management during major events, and preservation of neighborhood character. Del Mar participates in regional coastal planning and lagoon restoration efforts with neighboring jurisdictions.
Events and Culture
The Del Mar racing season, San Diego County Fair, and numerous concerts and festivals at the fairgrounds define the city's public calendar. These events bring regional visibility while requiring careful coordination of parking, public safety, and resident quality-of-life concerns.
Fairgrounds and Racetrack
The Del Mar Fairgrounds and Del Mar Thoroughbred Club occupy land owned by the 22nd District Agricultural Association, a state entity. Lease agreements and land-use compatibility between fairground operations and adjacent residential neighborhoods remain ongoing topics of civic discussion and regional planning coordination.
Geography and Environment
Del Mar sits on bluffs rising above the Pacific, with canyons cutting inland toward the San Dieguito River corridor. Los Peñasquitos Lagoon forms part of the northern boundary, providing estuarine habitat and a regional trail connection. Coastal erosion, bluff stability, and sea-level rise are active planning concerns for city infrastructure and private property along the oceanfront.
Transportation and Connectivity
Interstate 5 passes through Del Mar, with local access via Via de la Valle and Camino del Mar. Coaster commuter rail stops at the Solana Beach station a short distance north, providing regional transit access. Local and regional bus routes serve the village and fairgrounds during major events. Del Mar's compact size makes walking and cycling practical for many daily trips within the city.
Looking Forward
Del Mar's planning agenda includes fairgrounds lease negotiations, lagoon restoration, bluff-top infrastructure resilience, and compliance with state housing requirements within land constraints. The 20th Street Del Mar project and village-area improvements represent infill development under active community review. Climate adaptation strategies address wildfire risk in canyon areas and coastal flooding along low-lying lagoon edges.
The City's Character
Del Mar compresses an unusual range of experiences into fewer than two square miles: quiet residential bluffs, a bustling village, international-caliber racing, and county-fair scale events — all within walking distance of the Pacific.
"Del Mar proves that civic identity is not measured in acreage — a racetrack, a fairground, and a bluff-top village can define a region's calendar and character from one of the county's smallest footprints."
Whether watching surf from Powerhouse Park, attending opening day at the track, or walking the lagoon trail at dawn, visitors encounter a city that has chosen preservation and event heritage over expansion — a deliberate identity maintained across more than six decades of incorporation.
