Prior to the submittal of a tentative map, the subdivider is encouraged to consult with the staff of the technical committee for technical advice and procedural instructions. Preliminary sketches of the subdivision may be submitted and discussed. The preliminary sketch would be to a scale and detail sufficient to indicate the essential characteristics of the subdivision, including the number, size and design of lots, the location and width of streets, the location of any important reservations or easements, the relation of the subdivision to all surrounding lands, and any other details necessary to enable a preliminary review. The technical committee may schedule a conference with the subdivider and appropriate city departments to discuss the preliminary map and make recommendations concerning the submittal of a tentative map.
