Infill is an urban planning term for increasing the population density in a space by converting pre-existing spaces into a more densely used structure. To literally "Fill-in". Adding a cottage in a back yard, tearing down a house and using the lot to build four apartments, and taking a parking lot and building a Dorm are all infill. Infill is done on a relatively small scale since it is in an already developed area and typically relegated to a single lot. Infill is somewhat common in Davis and will most likely increase with the demand due to the growing student population and high housing costs in town.
