Across the Los Angeles River from downtown Los Angeles is an unexpected sight, in the nation’s second-biggest city: a working lumber mill. The dusty, noisy mill is processing logs from the city itself. Angel City Lumber’s “whole purpose is to connect Angelenos to their community trees,” said founder Jeff Perry, by turning fallen local trees into wood products like tabletops, benches and flooring. The city of Los Angeles is home to over 10 million trees … an average of 2,000 trees are removed each year when they die and other reasons. …Angel City Lumber now works with municipal crews during tree removal, arriving in time to scoop up the trunks and bring them back to its mill to be processed into lumber. …Part of Perry’s vision involves rethinking the perception of street trees, chosen for ornamental or shade benefits, as the “perfectly good lumber” that most of those trees could become after their death.
