It is the intent of this growth management system to assure that residential development, remains within the limits established by the Petaluma General Plan as amended from time to time. It provides a mechanism for the city council to set growth-related development objectives including but not limited to maintaining a reasonable ratio of eastside to westside growth, encouraging infill and a mix of housing types, and assuring that essential public facilities and services are properly matched to proposed development. Furthermore, it is the intent of this chapter to improve the efficiency of the development review process and establish tentative map approval, final map approval (for subsequent project phases) or other appropriate development approval (for residential projects not requiring a land division) as the point at which allotments have been exercised.
