Infill housing can boost a city s economy. In such, cities encouraging the development of high quality urban neighborhoods of infill housing may help to lure back the middle class. Infill reduces sprawl. Directing the construction of new housing into existing urban areas conserves rural farmlands and open spaces. Infill is less auto-dependent.
Transportation planners love infill.
In-city residents drive less than suburban residents. Infill near downtown will be served by existing bus routes, and will provide additional riders with virtually no increase in service costs. Tri-Met, the Portland, Oregon transit agency has emphasized infill development near to its stations as a tool for building ridership. 4 When infill development put housing units within walking distance of shops and services, auto use is further reduced. It may be less costly for government to provide services to urban infill development than to suburban greenfield development.
