The rules and regulations governing plats and subdivision of land contained herein shall apply within the city and other land as permitted by state statutes. In the event of overlapping jurisdiction within the prescribed area, the extent of jurisdiction shall be determined and agreed upon between the city and the other municipality or municipalities concerned. Except in the case of resubdivision, this chapter shall not apply to any lot or lots forming a part of a subdivision recorded in the office of the County Recorder prior to the 1972 effective date of the county's first subdivision ordinance, nor is it intended by this chapter to repeal, annul or in any way impair or interfere with existing provisions of other laws or ordinances except those specifically repealed by, or in conflict with this chapter, or with private restrictions placed upon property by deed, covenant or other private agreement, or with restrictive covenants governing the land. Where this chapter imposes a greater restriction upon the land than is imposed or required by such existing provisions of law, ordinance, contract or deed, the provisions of this chapter shall control.
