In interpreting and applying the provisions of this Zoning chapter, the provisions shall be held to be the minimum requirements for the promotion of the public health, safety, morals, convenience, order, comfort, prosperity or general welfare. It is not intended by this Zoning chapter to interfere with, abrogate or annul any easements, covenants or other agreements between parties; provided, however, that where this Zoning chapter imposes a greater restriction upon the height of buildings or requires larger open spaces than are imposed or required by other resolutions, rules or regulations or by easements, covenants or agreements, the provisions of this Zoning chapter shall govern. If because of error or omission in the preparation of Official Maps any property in the jurisdiction of this Zoning chapter is not shown as being in a zoning district, the classification of such property shall be R-R Residential Recreational until changed by amendment.
