PLU du Havre - PLU ad hoc prescriptions (approved on 19 December 2019)

A prescription is in the form of a surface, linear or point-in-time information that appears on the graphic documents of the PLU. A prescription that is superimposed on an area of the PLU generally exerts an additional constraint on the regulation of the area.标注项以面状、线状或时点信息的形式呈现于PLU的图形文档内。若标注项叠加于PLU的某一区域，则通常会对该区域的调控施加额外约束。
