A 0.3 metre reserve (one foot reserve) is a strip of land 30 cm wide, running along the street frontage or perimeter of a property or perpendicularly across a road right-of-way that is deeded permanently or temporarily to a municipality as a condition of a subdivision agreement. This reserve as the effect of technically denying access to a property, or adjacent lands because the law requires that all land must have frontage on a public street to qualify for a building permit. The reserve is used as a means to control development until such time as various conditions are met or to prohibit development on lands that are not yet scheduled for development. The lifting of the reserves can result in the dedication of land as public highways or the conveyance of land back to the original or an adjacent owner.
