With a long history of partnerships with southern California agencies―including the City of Los Angeles, City of Pasadena, County of Los Angeles, San Bernardino Valley Municipal Water District, and many others―Stillwater scientists lead and build consensus around ecosystem restoration in conjunction with infrastructure and water management.
