In planning and developing a subdivision, the applicant or his agent shall comply with the general principles of design and minimum requirements for the layout of subdivisions set forth in Appendix I and with the rules and regulations concerning required improvements set forth in Article
V of these regulations, and in every case he shall observe the procedure hereinafter set forth.
Before undertaking the preparation of a subdivision plat, the applicant or his engineer should consult with the Planning Commission or its agent to ascertain the location of proposed major roads or highways, parkways, parks, playgrounds, land use and other planned developments, as well as the zoning, sanitation and other regulations and the requirements for drainage and utilities relating to, affecting or applying to the subdivision of his property. He should bring with him a sketch of his property, to approximate scale, showing the boundaries, general topography, important physical features and other significant information, as well as his conception or proposed scheme for the development of the property. The Planning Commission or its agent will try to assist the applicant by furnishing information and advice so as to expedite matters for the applicant, save him from unnecessary expense and promote the best coordination between the plans of the applicant and those of the community. The Planning Commission, however, will not undertake to design the subdivision or to perform other services for which a qualified land planner should more properly be engaged.
