Surveys
in connection with maps prepared pursuant to this chapter shall be
made in accordance with standard practices and principles for land
surveying. A traverse of the boundaries of the subdivisions and all
lots and blocks shall close. Sufficient data shall be shown to determine
readily the bearing and length of each line. Dimensions of lots shall
be net dimensions, and no ditto marks shall be used.
Show two measured ties from the boundary of the subject property
to existing Horizontal Control stations having California Coordinate
values of third order accuracy or better, as published in the County
of San Diego's Horizontal Control Book. These tie lines to the existing
control shall be shown in relation to the California Coordinate System
(i.e., grid bearings and grid distances). All other distances shown
on the map are to be shown as ground distances. A combined factor
for conversion of grid-to-ground distances shall be shown on the map.
If there are no acceptable horizontal control stations within
one-half mile of the subject property, then the engineer or land surveyor
may make a written request to the City Engineer for additional control
stations within the subject area.
The City may provide a coordinated monument (using the North
American datum of 1983) by tying either a section, quarter-section,
rancho or other appropriate land net corner or road centerline which
is intervisible with an existing monument in the local control network.
In the event the City is unable to provide an acceptable horizontal
control station within one-half mile of the subject property within
30 days of written request, this requirement may be waived.
None of the above will preclude a person, authorized to practice
land surveying, from performing the necessary work to meet the requirements
of this section.
