These districts are intended to be located in areas of the city that have existing lots which were platted in the nineteenth or early twentieth century with small lot area where modern zoning requirements would be impractical or would make the lots unbuildable. The districts are intended to be used for single-family residential development with low to moderate population densities. Additional permitted uses, by review of the planning commission, include educational facilities and other uses normally required to provide the basic elements of a balanced and attractive residential area.
