Palo Alto Airport (IATA: PAO, ICAO: KPAO, FAA LID: PAO) is a general aviation airport in the city of Palo Alto in Santa Clara County, California, United States, near the south end of San Francisco Bay on the western shore.

Fifteen miles of hiking and biking trails, affording multiple opportunities for birdwatching, form part of the adjacent 1,940-acre (785 ha) Palo Alto Baylands Nature Preserve[7] and Byxbee Park[8].

[12] In 1989 a comprehensive area history analysis was conducted by Earth Metrics,[citation needed] based upon review of extant aerial photographs.

Comparison of the aerial photographs indicate that no development had begun in the vicinity prior to 1956 other than the Palo Alto Airport and the Regional Water Quality Control Board Plant (terminus of Embarcadero Way).

In the 1980 aerial photograph, the Harvey Gum Factory is standing, and additional infill construction can be seen in the area such as the Baylands Business Park adjacent and to south of the site and the structure now located at 1860 Embarcadero Road.
