How tall can you build near H80 without filing?
The notice surface rises 1 foot for every 50 feet of horizontal distance from the nearest point of the nearest runway, starting at the runway's elevation. Using the lowest runway-end elevation, 829 ft above sea level:
| Distance from nearest runway | Notice required above (height over 829 ft) | …which is this elevation (AMSL) |
|---|---|---|
| 250 ft | 5 ft | 834 ft |
