(a) On reaching conclusions, informally as recommended in Section 1109.01(a) and (b) regarding the general program and objectives, the subdivider shall cause to be prepared a preliminary plat, together with improvement plans and other supplementary material as specified in subsection (f) hereof.
(b) One copy of the preliminary plat and supplementary material specified shall be submitted to the Planning Commission with written application for conditional approval at least ten days prior to the meeting at which it is to be considered.
(c) Following the review of the preliminary plat and other material submitted for conformity thereof to these Regulations, and negotiations with the subdivider on changes deemed advisable and the kind and extent of improvements to be made by him, the Planning Commission shall, within thirty days act thereon as submitted, or modified, and if approved, the Planning Commission shall express its approval as conditional approval and state the conditions of such approval, if any, or if disapproved, shall express its disapproval and its reasons therefor.
(d) The action of the Planning Commission shall be noted on three copies of the preliminary plat, referenced and attached to any conditions determined. One copy shall be returned to the subdivider and one copy delivered to the appropriate official of the municipality and one copy retained by the Commission.
(e) Conditional approval of a preliminary plat shall not constitute approval of the final plat. Rather it shall be deemed an expression of approval to the layout submitted on the preliminary plat as a guide to the preparation of the final plat which will be submitted for approval of the Planning Commission and for recording upon fulfillment of the requirements of these Regulations and the conditions of the conditional approval, if any.

D. Utilities on and adjacent to the tract: location, size and invert elevation of sanitary, storm and combined sewers; location and size of water mains; location of gas lines, fire hydrants, electric and telephone poles, and street lights; if water mains and sewers are not on or adjacent to the tract, indicate the direction and distance to, and size of nearest ones, showing invert elevations of sewers.

F. Subsurface conditions on the tract, if required by the Planning Commission and the City Service Director upon information provided by a licensed professional engineer: location and results of tests made to ascertain subsurface soil, rock and ground water conditions, depth to ground water unless test pits are dry at a depth of five feet; location and results of soil percolation tests if individual sewage disposal systems are proposed.

B. Other proposed rights of way or easements; location, width and purpose.
