Hollaway biologists have conducted species-specific surveys, migratory bird surveys, and ASTM-compliant Phase I Environmental Site Assessments. Hollaway maintains close and frequent coordination with Flood Control District, as well as state and federal regulatory agencies to ensure appropriate environmental compliance is achieved. Hollaway also works closely with the engineering teams in identifying environmental constraints, developing alternatives, and informing project designs for programmatic flood damage reduction within the watershed.
