means The length of a property's boundary that runs along a street, river, or other reference line — the strip where your land meets the public world.

from Straightforward carpentry of English: 'front' (from Old French 'front,' from Latin 'frons,' the forehead or brow — the face you present to the world) plus the noun-forming suffix '-age,' which turns an action or quality into a measurable thing (as in 'acreage' or 'mileage'). So frontage is literally 'the amount of front' a piece of land has — its forehead, measured in feet.
