Aerial view · 29C

No FAA diagram published

The FAA does not publish an Airport Diagram (APD) for 29C — most non-towered fields, heliports, seaplane bases, and private strips fall here. Below: aerial imagery showing the actual field, runways, taxiways, and surroundings.

Runways at 29C

2 runway ends on file. Longest: 1,800 ft. Max gradient: 0.83%

Designator Heading Length Width Surface Lighting Gradient
18 — 1,800 ft 85 ft TURF-F No 0.83%
36 — 1,800 ft 85 ft TURF-F No 0.83%

Source: in-app airport database (runway lengths + headings), OurAirports for surface, width, lighting. Gradient computed from FAA NASR runway-end elevation deltas (the published RWY_GRAD field is empty in 99.99% of NASR rows; we derive it from the elevations the FAA does publish).
