16.20.010 General.¶
The form, contents, accompanying data and filing of the final map shall conform to the provisions of the state Subdivision Map Act and this chapter. The final map shall be prepared by or under the direction of a registered civil engineer or licensed land surveyor. (Prior code § 25.72)
16.20.020 Phasing.¶
Multiple final maps relating to an approved or conditionally approved tentative map may be filed prior to the expiration of the tentative map if the subdivider, at the time the tentative map application is filed, notifies the planning director in writing of the subdivider’s intention to file multiple final maps on the tentative map in accordance with Section 16.16.020(D)(3). In providing the notice, the subdivider shall not be required to define the number or configuration of the proposed multiple maps. The city council shall approve the sequence of map approvals. After filing of the tentative map application, the planning director, the public works director and the subdivider shall concur in the filing of multiple final maps.
The filing of a final map on a portion of an approved or conditionally approved tentative map shall not invalidate any part of the tentative map. Each final map which constitutes a part, or unit, of the approved or conditionally approved tentative map shall have a separate subdivision number. The subdivision improvement agreement executed by the subdivider shall provide for the construction of improvements as required to constitute a logical and orderly development of the whole subdivision. (Prior code § 25.73)
16.20.030 Survey required.¶
An accurate and complete survey of the land to be subdivided shall be made by a registered civil engineer or licensed land surveyor. All monuments, property lines, centerlines of streets, alleys and easements adjoining or within the subdivision shall be tied into the survey. The allowable error of closure on any portion of the final map shall not exceed 1/10,000 for field closures and 1/20,000 for calculated closures.
At the time of making the survey for the final map, the engineer or surveyor shall set sufficient durable monuments to conform with the standards described in Section 8771 of the Business and Professions Code so that another engineer or surveyor may readily retrace the survey. At least one exterior boundary line shall be monumented prior to recording the final map. Other monuments shall be set as required by the city engineer. (Prior code § 25.74)
16.20.040 Form.¶
A. Final maps shall be clearly and legibly drawn, printed or reproduced by a process guaranteeing a permanent record in black on tracing cloth or polyester base film. Certificates, affidavits and acknowledgments may be stamped or printed on the map with opaque ink if the ink surface is coated with a suitable substance to assure permanent legibility. The size of the sheets shall be eighteen (18) by twenty-six (26) inches, leaving a margin of one inch on all sides.
B. The title sheet shall contain the title consisting of the subdivision number and the name of the tract and such name shall not be the same as the name of any existing city, town, tract or subdivision of land into lots, of which a map or plot has been previously recorded, or so nearly the same as to mislead the public or cause confusion as to the identity thereof, and a subtitle or general description of all the property being subdivided by reference to maps which have been previously recorded. In case the property included with the subdivision lies wholly within the corporate limits of the city, the following words shall appear before the title: “In the City of St. Helena”; if partly within the city limits, the following words shall be used: “Lying within and adjoining the City of St. Helena.” Reference to tracts and subdivisions in the description must be worded identically with original records and reference to book and page of record must be complete. Every sheet comprising the map shall bear the number, name, scale, north point, legend, sheet number and number of sheets comprising the map. Below the title shall be clearly noted the basis of bearing for the survey.
C. When the final map consists of more than two sheets, a key map showing the relation of the sheets shall be placed on the first map sheet.
D. The scale of the final map shall be one inch equals one hundred (100) feet, unless otherwise approved by the public works director.
E. The map shall show clearly what stakes, monuments or other evidences were found on the ground to determine the boundaries of the tract. The adjoining corners of all adjoining subdivisions shall be identified by lot and block numbers, tract name and place of records, or by section, township and range, or other proper designation.
F. Sufficient data must be shown to determine readily the bearing and length of every lot line, block line and boundary line. Dimensions of lots shall be given as to net dimensions to the boundaries of adjoining streets and shall be shown in feet and hundreds of feet. No ditto marks shall be used. Lots containing one acre or more shall show net acreage to nearest hundredths. Bearings and distances of straight lines and such radii and arc lengths for all curves as may be necessary to determine the location of the centers of curves shall be shown.
G. The boundary of the tract shall be designated by a colored border applied to the tracing. Such border shall not interfere with the legibility of figures or other data.
H. In any subdivision, all lots shall be numbered consecutively with no omission or duplications throughout the entire subdivision and for future units of any subdivision which has the same tract name but is designated by different units. No block division or numbering is required, but if desired by the subdivider, then each block shall be numbered consecutively. Circles or other geometric figures shall not be drawn around numbers. Each lot must be shown entirely on one sheet.
I. The map shall show the center and side lines of all streets, the total width of all streets, the width of the portion being dedicated and the width of existing dedications and the widths each side of the center line, also the width of railroad rights-of-way appearing on the map.
J. The map shall show the center and/or side lines of all easements to which the lots are subject. The easements must be clearly labeled and identified and, if already of record, its recorded reference given. If any easement is not definitely located of record, a statement of such easement must appear on the title sheet. Easement for storm drains, sewers and other purposes shall be denoted by dotted lines. Distances and bearing on the side lines of lots which are cut by an easement must be arrowed or so shown that the map will indicate clearly the actual lengths of the lot lines. The width of the easement and lengths and bearings of the lines thereof and sufficient ties thereto to definitely locate the easement with respect to the subdivision must be shown. If the easement is being dedicated by the map, it shall be properly set out in the owner’s certificate of dedication. All notes or figures pertaining to easements shall be considerably smaller and lighter than those relating to the subdivision itself.
K. The final map shall particularly define, delineate and designate all lots intended for sale or reserved for private purposes and all parcels offered for dedication for any purposes, with all dimensions, boundaries and courses clearly shown and defined in every case. Any or all of the parcels of land intended for any public use, except those parcels, other than streets, intended for exclusive use of the lot owners, their licensees, visitors, tenants and servants, in the subdivision shall be offered for dedication for public use. Parcels offered for dedication but not accepted shall be clearly designated as such on the map.
L. The following certificate and acknowledgments and all others now or hereafter required by law shall appear on the final map, such certificates may be combined where appropriate:
- A certificate signed and acknowledged by all parties having any record title interest in the subdivided real properties consenting to the preparation and recordation of the map; provided, however, that the signatures of parties owning the following types of interest may be omitted if their names and nature of their interests are endorsed on the map:

c. Interests in or rights to minerals, including but not limited to oil, gas or other hydrocarbon substances, if (i) the ownership of such interests or rights does not include a right of entry on the surface of the land; or (ii) the use of the land or the surface thereof in connection with the ownership of such interests or rights is prohibited by zoning or other governmental regulations;
