(Ord. 1137, Exh. A, 2003)
A. 
Contour grading techniques are required on all graded slopes. The goals of the contour grading concept are as follows:
1. 
To create a natural appearing hillside development;
2. 
To provide graded slopes that resemble surrounding natural terrain;
3. 
To mitigate the need for large retaining walls and other manmade features that detract from the natural, rural feel of the area.
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.
C. 
Retaining Walls.
1. 
Retaining walls may not exceed six feet in height and should be designed to be as short as possible.
2. 
Where possible, retaining walls should be curvilinear to blend with the existing grades and topography.
(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)
A. 
All signs shall comply with Chapter 18.156 of this title regarding signs in single-family residential zones.
(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.
