3. Dwelling Environment and Type of City Planning-related terms
Width and Road Abutting on the Site
An inquiry was made about the width and condition of paved roads abutting on the site of the housing unit.
The width includes those of sidewalks and gutters, and when there are two or more abutting roads, the widest one should be mentioned.
If the site of the housing unit only abuts on a vacant lot or park but not on any road, or if the site only borders a road for a length less than 2 meters, then it should be defined as "not abutting on." However, if the site is adjacent to open ground such as a station square, such ground should be provisionally regarded as a road 10 meters in width or wider for the sake of convenience.
