Applications for variances or special use permits shall be accompanied by a site plan for the proposed development. Such site plan shall be drawn to scale and shall show all existing and proposed structures, parking spaces, driveways and driveway openings, outside storage areas and signs. It shall also show all water bodies and all landscape features such as fences, walls, planting areas, walks and buffer strips, and such other information as may be required by the Board. In appropriate circumstances, strict compliance with some of the requirements of this provision may be excused or waived by the Board where strict compliance is unnecessary given the size or scope of the project involved. In every case, however, the site plan with all structural improvements or additions shall be drawn to scale in relation to lot lines.
