The city has brought in a herd of 100 goats to clear the thick and tangled weeds from a hillside lot next to the historic Angels Flight railway.
Leaders of the Los Angeles Community Redevelopment Agency which brought in the animals say the goats are cheaper and more environmentally friendly than humans with gas-powered machines.
Agency head Cecilia Estolano says the South African Boer goats are being rented for $3,000.
The goats are proving popular with office workers and commuters coming off the nearby Metro Red Line subway station, many of whom are stopping to snap pictures.
The lot will eventually be home to a third tower for the mixed-use California Plaza.
