Special District Designation on Public Parks

When a Special Natural Area District is designated on a public park or portion thereof, any natural features existing on December 19, 1974, within such area shall not be removed, destroyed or altered unless authorized by the City Planning Commission. As a condition for granting such authorization, the Commission shall find that any alteration of natural features is the least alteration required to achieve the purpose intended and such authorization is consistent with the intent of the Special Natural Area District.
