(a) The City Council finds that:
(1) There are hills and ridges within the City which
because of their physical dominance of the City's landscape
constitute significant natural topographical features and
comprise a large part of the natural open space and scenic
resources of the community;
-1-
(2) It is desirable to require in these areas an
alternative approach to traditional and conventional flat
land practices of residential development, to keep grading
and cut and fill operations consistent with the retention
of the natural character of the hillside and ridgeline
areas, and to preserve the predominant views both from and
of the hillside and ridgeline areas;
(3) Active and passive recreational open spaces are
desirable and necessary to maintain the quality of life
enjoyed by the residents of the community;
(4) The retention of scenic hillsides and ridgelines
in as near a natural state as is feasible consistent with
the rights granted by law to property owners to develop
their properties is important to the community's aesthetic
qualities andd will preserve a desirable visual identity of
the City;
(5) Hillside development requires special attention
to the provision of public facilities and improvements
in order to protect the health and safety of human life
and property;
(6) The repair and stabilization of unsafe slide
areas is crucial to the health, safety and welfare of
the community, and to the preservation of both public
and private investments in such areas;
_ (7) The City Council recognizes that each property has
its own unique characteristics, including, but not limited
to topography, tree-cover an visual impact. The regulations
in this chapter are intended to provide flexibility in the
treatment of the development of individual properties as
indicated by their uniqueness rather than to provide a
fixed set of strict standards applicable in the same manner
to all properties. In this way each property can be
developed to it full potential consistent with the land use
constraints as imposed by this chapter and other applicable
land use regulations;
(8) The imposition of the regulations imposed by
this chapter may protect the City from liability for soils
instability by requiring that consideration be given to
the presence of critically expansive soils or other soils
problems.
(b) The purposes of this chapter are to:
(1) Preserve significant features of scenic hillsides
and major ridgeline areas in essentially their natural state
as part of a comprehensive open space system;
(2) Keep the semi-rural qualities of the City by
preserving its open and uncluttered natural topographic
features;
-2-
(3) Encourage in these areas an alternative approach
to conventional flat land practices of development;
(4) Keep grading and cut and fill operations consistent
with the retention of the natural character of the scenic
hillsides and major ridgelines;
(5) Minimize the water runoff and soil erosion
proDlems incurred in adjustment of the terrain to meet
on-site and off-site development needs;
(6) Insure that the open space as shown on any
development plan is consistent with the open space element
shown on the General Plan;
(7) Preserve the predominant views of the scenic
hillsides and major ridgelines and to retain the sense
of identity and image that these areas now impart to the
City and its environs;
(8) Require retention of trees and other vegetation
which stabilize slopes, retain moisture, minimize erosion
and enhance the natural scenic beauty and safety qualities
of the hills;
(9) Require planting wherever appropriate to maintain
necessary cut-and-fill slopes, to stabilize them by plant
roots, and to conceal the raw soil from view; and
(10) Require retention of natural landmarks and
prominent natural features tht enhance the character of
the City.

use district to which the land is classified.
(b) Prohibited deve]opmejl~ No development is permitted
within 100 feet (measured vertically) of the centerline of a
major ridgeline (the line running along the highest portion)
except when development plan approval is granted by the Planning
Convission in accordance with section 8-5010.

(a) ~9.q~~_~ ~. A person who desires to erect a
structure or to grade or improve scenic hillside land must
receive a scenic hillside development permit. The application
may be combined with an application for a building permit,
grading permit, conditional use permit, tentative subdivision map
approval or other land use entitlement. (Existing development
requiring a grading or building permit for exterior modification
shall be subject to the development permit process.)
(b) Applicat.~Qfk_i~l~ informatioG. An applicant shall file an
application on a form provided by the City. The Planning
Director may require such supplemental plans and information as
may be needed to properly review the application. Examples of
supplemental plans and information that may be required are:
(1) preliminary soils and geological reconnaissance
report;
(2) preliminary grading plans indicating existing and
proposed grades and retaining walls on a drawing to a
scale of not less than one inch equals twenty feet and
contour intervals not greater than two feet;

existing structures, streets, driveways, parking,
utilities, etc;
(4) conceptual landscaping plans;

entitlement. In the case of an application which requires only
grading or building permit approval for sites located on scenic
hillside land, the Planning Director is the reviewing body. The
director may refer an application to the Planning Commission for
review and recommendation. In all other cases of applications
requiring approval in scenic hillside or major ridgeline areas,
the Planning Commission shall be the reviewing body (section
8-5010).

The minimum lot area shall not be less than that prescriDea
by the applicable land use district and which is consistent with
the General Plan. However, the required lot areas may be
increased or decreased above or below the minimum when the
reviewing body finds that it is necessary to do so because of the
physical terrain in order to assure that there will be a suitable
building site for the approved use. In determining whether it is
necessary to increase or decrease the lot area, the reviewing
body shall apply the standards set forth in Section 8-5007. Lot
area reductions shall be subject to the standard variance
procedure.
(a) In reviewing an application the reviewing body shall
consider the following factors: slope, soil stability, drainage,
soil characteristics, seismic factors, existing and future
development, view shed, vehicular access, potential traffic
congestion, fire risk, wildlife, and impact on existing
vegetation.
(b) The site plan shall provide an appropriate developable
area on the site consistent with the site's constraints in
relation to the review and approval criteria set forth in this
section and in the Danville Hillside/Ridgeline Development
Standards. These Standards provide criteria for architectural
design, landscaping, grading, lighting, etc.
