Under cluster zoning, the size of lots within a designated residential area and the required frontage can be reduced if the development abuts a declared wetland or national forest.

While the proximity to wetlands or national forests may influence development considerations, it is not a criterion that allows for reduced lot sizes or required frontages under cluster zoning. Instead, this factor pertains to environmental regulations that ensure protection of natural resources rather than the density requirements set out in the master plan.

Abutting state-owned land does not inherently provide justification for reducing lot sizes or frontages under cluster zoning regulations. Similar to wetlands, state-owned land may have its own restrictions or guidelines, but it does not directly address the overall density parameters that govern cluster developments.

Inclusion of commercial or industrial uses within a residential development does not qualify for reduced lot sizes or frontages under cluster zoning. The focus is primarily on residential density management, and the presence of non-residential elements would typically require adherence to different zoning regulations.
