The Infill area constitutes what historically has been the central core of Roseville, as well as the areas that were the focus of growth in the City until the early 1980's.

With the exception of scattered parcels of limited acreage, the Infill area is close to being fully developed. The land use in this area incorporates a mix of residential neighborhoods, commercial and industrial uses and amenities to serve the residents of the community.

The Infill area encompasses the oldest portions of the City but excludes the newly adopted Downtown Specific Plan area and Riverside Specific Plan area. Totaling 8,478 gross acres, the Infill area will accommodate approximately 39,157 residents at full build-out.
