A.
Contour
grading techniques are required on all graded slopes. The goals of
the contour grading concept are as follows:
B.
Contour
Grading Techniques. The following techniques and characteristics are
features of contour grading and shall be incorporated into the grading
design.
1.
Area Grading Instead of Individual Lot Grading. The intent of contour
grading is to study the slope appearance of the natural hillsides
in the project vicinity, and design a grading scheme which resembles
these natural features. In some cases, this may result in a greater
volume of grading to be performed in order to reach the desired design;
2.
Split-Level Pads Instead of Flat Pads. The intent is to better site
structures into, or along, hillside terrain. Split-level pads or other
creative grading approaches should be used;
3.
Where possible pads should follow contours when this type of solution
does not conflict with desirable drainage solutions. A series of small
pads that are curvilinear, irregularly-shaped and follow the form
of the hillside are preferable to large, square-shaped pads;
4.
Natural-Appearing Yard Areas. Contour grading shall be used to create
pads and yard areas which complement hillside features. Contour grading
shall not be used for the sole purpose of creating flat yard surface
areas;
5.
Smooth Transitions on Slopes. Graded slopes shall have rounded contour
edges to provide for smooth cuts and curvatures. Contour grading should
soften hard edges left by cut and fill operations where an adverse,
mechanically appearing, visual impact may occur;
6.
Varied Slope Bank Gradients. Graded slopes shall be designed to have
a variety of slope bank gradients to emulate natural conditions. For
example, instead of creating a solid 2:1 slope bank, a slope may commence
with a 5:1 gradient near the base and rise with 2:1, 3:1 and 5:1 gradients
to the top of the bank. In some cases, it may be appropriate to provide
1.5:1 slopes;
7.
Undulating Slope Banks. Graded slopes shall undulate to emulate natural
conditions. The intent of contour grading is to employ a variety in
the steepness and configuration of slopes. Contour grading should
be used to blend the graded slopes with the natural undulating character
of the hillside landform.
(Ord. 1137, Exh. A, 2003)
A.
Horse corrals may be permitted on Lots 3, 4, 6, 7 and 8 subject to the requirements set forth in this chapter and in Chapter 18.112 of this title.
B.
Minor
grading may be permitted within the non-development area for horse
corrals and tack facilities and, where possible, all trees shall be
preserved in place.
(Ord. 1137, Exh. A, 2003)
The intent of Area 2 of this specific plan is to create a single-family
development while maintaining as much as possible the rural feel of
the area. A major portion of achieving this intent is limiting street
width to reduce the dominance of paved area throughout the development
while providing basic access to the lots.
A.
Street
A (Extension of Valley Center Avenue). Street A is a private street.
Street A shall have a maximum width of two vehicular travel lanes
and no parking shall be permitted.
1.
An equestrian trail may be provided adjacent to the existing roadway
and may be located in the existing forty-foot right-of-way. This equestrian
trail shall provide a link between the existing city trail system
and access to the County Equestrian Staging Area.
2.
No widening of the existing roadway shall be permitted without prior
city council approval. Any application to widen the roadway shall
consider the following:
a.
Appropriateness of any grading or retaining walls associated with
the widening;
b.
Effect of any widening on existing trees;
c.
Effect of widening on the existing rural character of the road;
d.
Relationship of widening this segment of the road to other segments
of the road including those located outside the city of San Dimas;
and
e.
Vehicular, pedestrian and equestrian safety concerns.
B.
Street
B (as provided in Tract 52717). Street B shall have a right-of-way
of thirty-eight feet and a street width of twenty-eight feet. Parking
shall be permitted on only one side of the street and an equestrian
trail shall be provided that parallels the street.
C.
Street
Lighting. In an effort to reduce light intrusion on the Walnut Creek
Wilderness Park and to retain a rural atmosphere, the street lighting
within Area 2 of this specific plan shall not be required to meet
minimum standard street lighting levels addressed in Chapter 17 of
the San Dimas Municipal Code. For any development, the developer shall
submit a security lighting plan to the city for approval. The security
lighting plan may include minimal lighting along the street for safety
purposes.
(Ord. 1137, Exh. A, 2003)
A.
Slope
and Non-Development Area Maintenance. A declaration of covenants,
conditions and restrictions relating to the maintenance of the slope
areas on all lots, signed and acknowledged by those parties having
any record title to the land to be developed and which are enforceable
by the city shall be recorded. The covenants, conditions and restrictions
shall ensure that:
1.
All improvements included within the slope areas, such as landscaping
and irrigation, shall be maintained in a safe condition and a state
of good repair;
2.
Failure to maintain such improvements, located on slope areas, is
unlawful and a public nuisance endangering the health, safety and
general welfare of the public and a detriment to the surrounding community;
and
3.
The non-development area of each property shall be maintained in
a manner that is free of weeds and overgrown vegetation and in conformance
with the provisions of Section 18.504.390.B.
(Ord. 1137, Exh. A, 2003)
(Ord. 1137, Exh. A, 2003)
A.
Street
lighting shall conform to Section 18.504.340.C.
B.
Spot,
flood or decorative lighting that intrudes into the Walnut Creek Wilderness
Park shall not be permitted.
C.
Security
lighting may be permitted in the equestrian area when associated with
an approved horse keeping facility and when the security lighting
is approved by the director of community development.
(Ord. 1137, Exh. A, 2003)
A.
Prior
to the issuance of any building permits, a conceptual fencing plan
for Area 2 shall be approved by the development plan review board.
The community fencing plan shall clearly indicate the location, height,
type and materials and color selection for fencing along Gainsborough
Road and the Valley Center Avenue extension. In addition to the provisions
of the fencing plan, the following standards shall apply:
1.
Fences and walls within the front setback may not exceed forty-two
inches in height;
2.
The maximum height for any residential fence shall be six feet. Exact
location and style of fencing shall be as approved under the community
fencing plan;
3.
Corral fences shall be metal pipe construction, a minimum of five
feet in height. The maximum height of corral fencing shall be six
feet;
4.
In the non-development portion of the lot only black tubular steel
fencing six feet in height, or other approved fencing, may be approved
with development plan review board approval.
(Ord. 1137, Exh. A, 2003)
A.
Landscaping
in the Development Area. The general landscape design concept is to
maintain the natural scenic amenity represented by the existing natural
vegetation. Introduced plant materials and landscaping improvements
shall harmonize with the natural character of the site. Landscaping
shall be designed to blend with the existing native vegetation in
the Walnut Creek corridor. Informal patterns of native materials shall
be used. Formal patterns, unnatural appearing shapes or assertive
colors shall not be permitted.
B.
Landscaping
in the Non-Development Area and Common Areas. To the maximum extent
possible, these areas shall remain in their natural state with no
removal of vegetation. Native and native-compatible vegetation may
be planted and temporary irrigation installed, with approval of plans
by the development plan review board. No planting other than native
and nativecompatible vegetation is permitted in these areas and all
planting shall conform to the Specific Plan No. 4 Planting Guidelines
adopted by the city council.
C.
Landscape
Design Standards. All landscaping shall comply with the following
design standards:
1.
Landscape Plan. Prior to the issuance of any building permits, a
conceptual landscape and irrigation plan for all developer-installed
landscape areas shall be approved by the development plan review board.
The landscape and irrigation plan shall clearly indicate the general
location, size and species of plant material and the proposed irrigation
of the area.
2.
Plant Material List. Unless specifically approved by the development
plan review board, all landscape material shall be compatible with
the Landscape Planting Guidelines for Specific Plan No. 4 on file
in the community development department.
3.
Landscape Installation. All cut and fill slopes in excess of five
feet in vertical height shall be planted and irrigated to promote
growth of plants and to prevent erosion. In developing a site, the
developer shall plant and maintain all slopes until the property is
occupied by reason of lease or purchase. The developer shall provide
suitable guarantee, satisfactory to the city council, for planting
and maintenance as provided in this chapter. All manufactured slopes,
other than those constructed in rock, shall be planted or otherwise
protected from the effects of storm runoff erosion and shall be benched
or terraced as required to provide for adequate stability. Planting
shall be designed to blend the slope with the surrounding terrain
and development. Manufactured slopes in rock shall be provided with
soil pockets to contain landscaping where appropriate. Irrigation
facilities shall be required where necessary to provide for property
maintenance of the planted areas.
4.
Landscape Maintenance. To ensure maintenance of plant materials,
an automatic irrigation system shall be provided. Irrigation systems
shall be designed to provide uniform coverage and maximum water efficiency.
