of the approximately 2.90-acre Arroyo at Monrovia Station Project site located in Monrovia, Los Angeles County, California. The purpose of this report is to verify the type, location, and extent of potential sensitive biological resources within the Project site and vicinity. MIG conducted a field survey of the Project site on October 24, 2018. The Study Area for the field survey and records search encompassed the entire 3.03-acre block bounded by West Evergreen Avenue to the north, South Primrose Avenue to the east, West Pomona Avenue to the south, and South Magnolia Avenue to the west. This report provides a thorough description of the biological setting of the site and surrounding area, including the vegetation communities, potential habitat for special status plant and wildlife species, sensitive natural communities, wildlife migration corridors, and potential state- and federal-jurisdictional habitats. An assessment of the project impacts and recommended mitigation measures to avoid, minimize, or compensate for potential adverse
