Key legal question
Whether parcels 604 and 613 had to be treated as corner parcels with an angle bisector because they border a private road.
Extracted holding
No. The private road was not part of the public project and no angle bisector was to be applied; the first building depth of those parcels remained within the contribution perimeter.
Extracted reasoning
Under the benefit principle, perimeter duty depends on special advantage, not direct frontage. The angle bisector rule serves to avoid double burden only for parcels on two public roads. Here, use of the bisector would prevent full perimeter coverage and unduly relieve the parcels.
