The purpose of the Intermediate Density Residential Zone is to provide areas within the City which have the capacity to accommodate single-family dwellings in conventional subdivisions or planned unit developments. These areas are intended for service by municipal utilities and urban type street systems, and, consequently, the residents must be willing to support the costs associated with this density of development. Certain public facilities and other nonresidential uses are permitted when desirable conditions and safeguards are satisfied. This zone includes those areas in Hammond that were in Hammond's Low Density Residential Zone (R-10).
