This section applies in those instances in which a subdivider proposes to develop his land to a maximum density allowable under the existing zoning.

If the subdivider proposes reduced subdivision improvements premised upon a lesser density than allowed under current zoning, the requirements of paragraphs (5)A and (5)B of § 323-6(a) apply. In the event of phase development of larger land tracts - wherein subdivision of the total property is proposed to occur over a period of years - each and every map filed must stand on its own as to the requirements of this section.

In order to permit more flexibility to cope with difficulties due to topography and other natural or man-made features of Humboldt County, the minimum lot area in any zone or General Plan designation may be modified down to a maximum of fifty percent (50%) of the minimum lot size required. At the same time, no lot created by the subdivision shall be larger than 1.8 times the minimum lot size permitted under the applicable zoning or General Plan classification. Also, the number of lots shall not be more than would normally be allowed in the applicable zone or General Plan designation, nor shall the area of the total property in the before condition divided by the total number of lots to be created result in an average area less than that required in the applicable zone or General Plan designation.
