Book excerpt: The bestselling book about the Los Angeles River, originally published in 2001, is updated with an Afterword that includes the Los Angeles County 2021 Master Plan to improve the quality of life and ecosystem health in the region--all centered at the original source, the Los Angeles River. RIO-LA: Tales from the Los Angeles River 20th Anniversary Edition traces the history and lore of the Los Angeles River. When the book was first published in 2001, few people even regarded the river, but because of Morrison’s devotion to the topic, LA River has been rediscovered. The river has become the center of the county’s 2021 MasterPlan to reestablish it as the heart of the city, its lifeline to all things positive: an antidote to homelessness; a source of increased affordable housing; new jobs, good health; serenity. Morrison traces this rediscovery in her extensive new Afterword, following pages of river history, dating back to before the founding of the pueblo called Los Angeles. Together Morrison and Lamonica explore the river and the culture that evolves around this virtual oasis in a land of super highways and celluloid dreams.
