(A) The tentative map shall be prepared in a manner consistent with the requirements of this title as determined by the Planning Department.
(B) The tentative map shall be clearly and legibly drawn and shall contain not less than the following:
(1) The subdivision name and type of subdivision;
(2) The name, address and telephone number of the owner of the subject property, the subdivider and the person preparing the map, including any registration or license number;
(3) The names and numbers of adjacent subdivisions and the names of owners of adjacent unplatted land;
(4) Date, north arrow, graphic scale, contour interval and source and date of existing contours;
(5) Existing zoning and general plan designation and a statement of existing and proposed uses of the property as well as any proposed zoning and general plan changes, whether immediate or future;
(6) A vicinity map showing roads, towns, creeks, railroads and/or other data sufficient to locate the proposed subdivision and show its relation to the community;
(7) Existing topography of the proposed subdivision site and at least 100 feet beyond its boundary, including but not limited to: existing contours at two-foot intervals if the existing ground slope is less than 10%, and at not less than five-foot intervals for existing ground slopes equal to or greater than 10%. Contours shall not be spread more than 150 feet apart and a minimum of three contours shall be shown. A different interval may be allowed in areas where it would be appropriate;
(8) Within the proposed subdivision and within 100 feet of its boundary, the following shall also be shown:
(a) Any trees proposed to be removed or impacted shall be indicated by species, diameter at breast height and dripline of existing trees with a diameter at breast height of four inches or more;
(b) The location and outline of all existing structures identified by type and drawn to scale. Structures to be removed shall be so marked;
(c) The approximate location of all areas of potential stormwater overflow; the location, width and direction of flow of each watercourse; and the flood zone designation;
(d) The location, type and width of pavement, right-of-way width, grade and name of existing streets or highways;
(e) The width, purpose, location and identity and recording data of all existing easements; and
(f) The location and size of existing sanitary sewers, fire hydrants, water mains and storm drains, where appropriate (required where property is within a sewer or water district). The approximate slope of existing sewers and storm drains shall be indicated. The location of existing overhead utility lines on peripheral streets and within the subdivision shall be indicated.
(9) Proposed improvements to be shown shall include, but not be limited to:
(a) Typical sections of all streets shall be shown. Proposed private streets shall be clearly indicated. The location, grade, centerline radius and arc length of curves, pavement, right-of-way width and name of all streets shall be shown, where appropriate;
(b) The location and radius of all curb returns and cul-de-sacs;
(c) The angle of intersecting streets if the angle deviates from a right angle by more than four degrees;
(d) The approximate lot layout and the approximate dimensions and area of each lot and each building site. Engineering data shall provide sufficient detail to allow adequate environmental review. This detail may include the approximate finished grading of each lot, the preliminary design of all grading including the estimated amount of grading in cubic yards, the elevation of proposed building pads, the top and toe of cut-and-fill slopes to scale, the number of each lot and the elevation of adjacent parcels;
(e) Proposed contours at two-foot intervals shall be shown if the existing ground slope is less than 10% and not at less than five-foot intervals for existing ground slopes of 10% or more and a minimum of three contours shall be shown. A larger interval may be allowed for very large property, where appropriate. Existing contours shall be represented by solid lines. A separate grading plan may be submitted;
(f) Proposed recreation sites, trails and parks for private or public use;
(g) Proposed common areas and areas to be dedicated to public open space;
(h) The location and size of sanitary sewers, fire hydrants, water mains and storm drains, where appropriate (required where property is in a sewer or water district). Proposed slopes and approximate elevations of sanitary sewers and storm drains shall be indicated. The proposed routing of stormwater runoff generated by a 100-year storm and proposed method of mitigating runoff due to development and pollution due to storm water discharge shall also be indicated; and
(i) A statement as to intention of the subdivider in regard to slope planting and erosion control.
(10) The name or names of any geologist or soils engineer whose services were required in the preparation of the design of the tentative map;
(11) The minimum size of each sheet shall be 18 by 26 inches. A marginal line shall be drawn completely around each sheet, leaving an entirely blank margin of one inch. The scale of the map shall be not less than one inch equals 100 feet or as may be necessary to show all details clearly, and enough sheets shall be used to accomplish this end. The particular number of the sheet and the total number of sheets comprising the map shall be stated on each of the sheets, and its relation to each adjoining sheet shall be clearly shown. When four or more sheets are used, a key sheet shall be included. All printing or lettering on the map shall be of one-eighth inch minimum height and of such shape and weight as to be readily legible on prints and other reproductions made from the original drawings; and
(12) The subdivider shall specify any deviation from county standards. The justification for the deviation shall be explained on a separate sheet.
