The Renata City is more efficient than traditional municipalities.  There are fewer roads and traffic lights to maintain, garbage collection is easier, policing and emergency response costs less.  And it's economical and efficient for people who live here too, especially those who don't need a car. 

Besides including the latest environmental benefits, like geothermal heating and roof gardens, the Renata City is a densely built community with all the amenities residents could expect.  On-site schools, recreation, shopping, healthcare, and commercial enterprises will eliminate the need for residents to leave the area for their daily duties. 

With free and frequent subway service, and without interference from cars, this city will have unequaled mobility. 

Yet, it will also be very walkable to improve safety, physical fitness, and social interaction.  In neighborhoods where people routinely walk to work, to the store, or just for fun, the rate of vandalism and theft will drop.  When people talk to their neighbors they feel more connected to their community, leading to a higher quality of life for all.
