• B. Tentative maps shall be clearly and legibly drawn on one sheet, at not less than twenty-four inches in width and not more than forty-two inches in length.

• C. Tentative maps shall be drawn to an engineer's scale at a scale large enough to show all information clearly but not less than one inch to one hundred feet.

• D. In the event the size of the subdivision results in the need for the tentative map to be on more than one sheet, a map not exceeding the dimension set forth in subsection B of this section shall be submitted showing the entire subdivision on which is indicated the boundary of the subdivision, existing and proposed streets, street names, major existing geographical features, the proposed lot numbers and other information as may be necessary to describe the project.

• E. Elevations shall be based on U.S. Geologic Survey 1929 sea level datum.

• F. The contour interval shall not be greater than one foot if the ground slope is five percent or less, nor greater that two feet if the ground slope is between five percent and ten percent, and at any lesser interval as long as the contour lines measure no less than one hundred fifty feet apart (ground distance).

• (Ord. 471 § 3, 1990)

Tentative maps shall set forth the following information:

• A. Topographic contour and planimetric mapping accurately showing the existing terrain, within and extending a minimum of two hundred feet outside the perimeter of the property, including existing drainage channels and water-courses, irrigation ditches and culverts and the direction of flow thereof; pipes and structures, wells, springs, slide areas, trees, roads; underground, surface and aerial utilities and structures; and, the locations and names of all adjacent streets and underground improvements and facilities therein;

• B. The title, which shall be placed at the lower right-hand corner of the map which shall contain the subdivision number assigned by the county recorder and may contain a subdivision name (subject to approval by the planning commission), and shall be dated to reflect the current map status;

• C. The names, addresses and phone numbers of the legal owner of the property, the subdivider, and the surveyor or civil engineer who prepared the tentative map; signature and seal of the surveyor or civil engineer who prepared the tentative map; indicating the date of preparation;

• N. The location, easement widths, approximate grade, direction of flow, and type of all proposed on-site and off-site storm drainage and sanitary sewer systems;

• O. The location, easement widths and type of all proposed major on-site and off-site water facilities and systems;

• P. Proposed school, park, recreation and other public or private use areas other than singlefamily residential;
