Street names within the planning jurisdiction of the village shall be chosen so that they are of a simple phonetic spelling and so that no conflict will be created with the names of existing village streets. For streets within planned unit developments or property developed by the same developer, the street names shall be chosen to carry out a single theme of the development in which the particular street is located. The developer, in coordination with the administrative staff of the village, will propose area themes and street names which will be reviewed by the Plan Commission as part of its review of the final development plan or plat of subdivision.
