The Olmsted Brothers — a landscape architecture firm run by the sons of Frederick Law Olmsted, who famously designed Central Park in New York City — were behind the ambitious vision for LA’s parks. The plan similarly prioritized massive amounts of park space while also recognizing that, in sprawling Los Angeles, green space would need to be distributed throughout the region, rather than in one large, centralized park.

Many of the early ideas laid out by the Olmsted-Bartholomew plan are now used as benchmarks when it comes to public space. At the time, just 14 miles of Los Angeles County’s 70-mile shoreline were publicly owned. The plan proposed acquiring as much of the coastline as possible and setting aside a vast stretch of uninterrupted public beach, decades before the California Coastal Act prioritized maximizing public access to the state’s beaches. The plan suggested using schoolyards as much-needed neighborhood parks, an idea that persists today as a way for Los Angeles to quickly scale up park access. And crucially, the proposal aimed to place all residents within half a mile of a park, or about a 10-minute walk, a metric now used by the Trust for Public Land to measure park access. Olmsted and Bartholomew even suggested the inclusion of high desert landscapes as part of the plan, in part to protect Joshua trees.
