Except as otherwise provided in this chapter, and except as necessary and incidental to airport operations, no structures or tree shall be constructed, altered, maintained, or allowed to grow in any airspace zone created in § 152.20 so as to project above any of the imaginary airspace surfaces described in § 152.20. Where an area is covered by more than one height limitation, the more restrictive limitations shall prevail.
