[1] Since 1975, there have been intents to develop the Greater Port Harcourt urban centre, although the construction project was not implemented nor was it fully abandoned.

This layout comprises clusters of neighbourhoods: low, medium and high densities, mixed use complexes, schools, churches, golf course and estates, internal road networks and storm water drains.
