The City of San Diego is soliciting proposals from qualified consulting firms to provide as-needed airport planning and environmental services in support of the City’s two general aviation airports. The selected consultants will deliver professional services under task orders over a five-year period, supporting federally and locally funded airport projects. Work includes airport-related environmental analysis, documentation, and compliance in accordance with Federal Aviation Administration guidance and regulations. Services may also include project design and planning support for grant-funded and airport enterprise-funded initiatives. Contracts operate as on-call agreements supporting capital improvements, regulatory compliance, and long-term airport development.
