the type of development contemplated. The following principles and standards shall be
observed:
1. Minimum Area - Size.
The minimum area and dimensions of all lots shall conform to the requirements of
the zoning ordinances of Salt Lake City for the district in which the subdivision is

1. Any specific subdivision approval conditions regarding fencing;
2. Material specifications and illustrations necessary to determine compliance
with specific subdivision approval limitations and the standards of this section.
(b) Field fencing of designated undevelopment areas. Fencing on areas identified
as "undevelopable areas" or "transitional areas" on any subdivision platted after
November 4, 1994 or any lot previously platted which identifies "undevelopable area" or
"transitional areas" shall be limited to the following:
1. Low visibility, see -through type, ownership boundary designation fencing,
consisting of flat black colored steel "T" posts and not more than four (4) strands of
non -barbed steel wire, strung at even vertical spacing between such "T" posts, and
erected to a height of not more than 42 inches above the natural ground surface.
2. Fencing boundary lines shall not be cleared of native brush or vegetation
so as to create a devegetation line visible from off site,

be changed by grading activities.
4. Fence materials and designs must not create a hazard for big game wildlife
species to cross.
5. No field fencing shall be erected in conflict with pedestrian easements

(b) Where higher standards have not been established as specified in subsection
(1) of this section, all streets and arterioles shall be platted according to the following
minimum widths, except where it can be shown by the subdivider, to the satisfaction of
the Planning Commission, that the topography or the small number of Tots served and
the probable future traffic development are such as to unquestionably justify a lesser
standard.

8. Ridge and gully topographic features protection.
(a) The City has determined that regulations are necessary to limit the
inappropriate encroachment of urban development into areas of significant foothill
ridges and gullies topographic features. These inappropriate encroachments may
negatively impact views, vegetation, fire protection, drainage and other public concerns
unless carefully considered.
(b) Significant foothill ridgelines are defined, for the purposes of these regulations,
to mean any portion of an elaborate system of forking ridge topographic features which
dominate the north and east foothill and mountain backdrops to urban Salt Lake City,
and which are identified upon the "Protected Ridgeline and Gully Maps of Salt Lake
City".
(c) Significant foothill gullies and drainage courses are defined, for the purposes of
these regulations, to mean any stream course or intermittent stream course topographic
feature which is identified upon the adopted "Protected Ridgeline and Gully Maps of
Salt Lake City".
(d) The "Protected Ridgeline and Gully Maps of Salt Lake City" consisting of one
overview map and twenty detailed maps are hereby adopted and incorporated by
