The Planning Board will study the preliminary development plans, the application and the environmental assessment, considering the comments of the internal and external review agencies. Attention will be given to the arrangement of the uses and buildings, the relation to the topography of the land, other factors, such as vegetation, wetlands, floodplain, sewage disposal, drainage, water needs, trip generation, recreation/open space needs, and such other concerns as may be appropriate. The Planning Board may recommend changes in the plan which should be revised prior to the Planning Board action.
