It is not the intent of this title to repeal, alter or annul, or in any way impair or interfere with, existing provisions of other laws or ordinances or with private restrictions placed upon property by deed, covenant or other private agreement, or with restrictive covenants or easements running with the land to which the city is a party. Where this chapter or the planning commission imposes a greater restriction upon the land than is imposed or required by such existing provisions of law, ordinance, contract, covenant or deed, the restrictions of the planning commission and this chapter shall govern. [Ord. 01-05 § 7.]
