Moreno Valley City Zoning Code
CHAPTER 9
16 DESIGN GUIDELINES
§ 9.16.010 Introduction and scope of guidelines.
A.
The city of Moreno Valley design guidelines are intended to promote quality site planning and architecture without restricting innovation or creativity. These guidelines provide the city's policy with respect to the quality of design expected for all projects. However, it is recognized that each project represents a unique development opportunity which is intended to be enhanced by the guidelines, not stymied by them. Compatibility with surrounding development is emphasized to achieve a unified and sensitive appearance, but variety and distinctiveness in design and architectural styles are encouraged.
B.
The design guidelines reflect the Moreno Valley general plan design policies and objectives, functioning as a tool for the general public, project developers, city staff and reviewing boards and commissions.
C.
These guidelines will help apply the city's design standards to new development and to remodels, upgrading design citywide and implementing the general plan's policies.
D.
Several design philosophies prevail throughout the guidelines. These include compatibility, sensitivity, human scale, variety, function and aesthetics. When combined and tailored for specific uses, these philosophies should yield high quality products that are consistent with the general plan's intent, practical and pleasing to the eye.
 Role of the Design Guidelines |
 Users of the Design Guidelines |
 |
(Ord. 359 (Attach. 2), 1992; Ord. 426 § 3.1, 1994; Ord. 475 § 1.4, 1995; Ord. 694 § 1.1, 2005; Ord. 817 § 3.4, 2010; Ord. 826 § 3.6, 2011)
§ 9.16.020 Generally.
A.
Design principles rule the design process, shaping and combining forms to provide visual images, functional spaces and to evoke emotional response. In development projects, design principles must be recognized and integrated into the proposal's design concept. When design principles are neglected, mistreated or disregarded, the project's images will be negative, spaces will not function properly and the emotional responses will not be as intended.
B.
The following paragraphs and figures help to illustrate the various design principles and how they apply to project design. These concepts, vital in urban design, site planning, architecture, landscaping, lighting and sign design, will guide project review. Briefly, these principles are:
(Ord. 359 (Attach. 2), 1992)
§ 9.16.030 Mass.
Mass is described in three dimensional forms, the simplest of which are cubes, boxes, cylinders, pyramids and cones. Massing shapes buildings. Large massing emphasizes and small massing subdues building elements. Interior spaces, based on the building's function, dictate massing patterns. Voids, or open spaces in massing, can alter the appearance of a simple mass, making it more interesting and less imposing.
 Simple Mass |
 |
 Examples of Scale |
(Ord. 359 (Attach. 2), 1992)
§ 9.16.050 Proportion and rhythm.
Proportion and rhythm, like scale, describes the relationship of building components to each other or of one building to another. Proportion and rhythm relates to the spacing of elements and can be described in terms of balance and emphasis.
A.
Proportion is the ratio of one dimension to another, like the width of a building to its height.
B.
Balance describes the visual equality between elements. Balanced elements may be symmetrical or asymmetrical, but their placement will produce similar visual impact.
C.
Unequal proportions create directional emphasis, usually horizontal or vertical. A unique element may also create emphasis, using its prominence to provide a focal point.
 |
(Ord. 359 (Attach. 2), 1992)
§ 9.16.060 Texture.
Texture refers to the roughness and pattern of the surface material. Detailed textures can add intimate scale.
 Patterns and Materials Create Texture |
(Ord. 359 (Attach. 2), 1992)
§ 9.16.070 Color.
Color is an important design feature, varying by hue (red, blue, yellow) and by tone (lightness or darkness). Colors advance or recede depending on the tone and intensity of the hue. The main body of the building, window trim and parapets, window sashes and roof and roof overhangs are building elements that can effectively use color. Some buildings incorporate materials that provide color in their natural state, such as brick, stone or clay tiles.
(Ord. 359 (Attach. 2), 1992)
§ 9.16.080 Light and shade contrast.
Projections, recesses, patterns and textures contrast light and shade. The creative use of light and shade is an effective design tool giving a three-dimensional quality to building façades. Both the thin line of shade along a molded cornice or the deep shadow of a recessed entrance add definition to a building design and enrich the building's appearance.
 Examples of Light and Shade Contrast |
(Ord. 359 (Attach. 2), 1992)
§ 9.16.090 Solid-to-void contrast.
The solid-to-void relationship between the total wall surface and its openings (such as doors, windows or arches) is basic to the way a building is perceived. Older style buildings had more wall surface than openings, reflecting the building materials' inability to span wide spaces. In many modern structures, particularly retail uses and certain wall office buildings, the window area predominates, creating an open feeling. Where window and wall areas are equal, the building can be viewed either as a wall with windows or as windows surrounded by a wall. This ambiguity creates static design, where neither element dominates.
(Ord. 359 (Attach. 2), 1992)
§ 9.16.100 Unity/diversity.
A.
Elements of well-designed buildings convey a single idea or theme when viewed as a whole. Individual buildings should have unity in scale, proportion, color and balance. For example, a Neo-Classical office building has a symmetrical façade, tall columns and oversized doors, elements intended to convey both a monumental feeling and a sense of order and structure. Each element is unique, but they make a unified statement in combination.
B.
A change of pace (diversity) from an established pattern can serve as a landmark or focal point and is particularly suitable if the distinctiveness in architecture or plan also denotes a difference in use.
(Ord. 359 (Attach. 2), 1992)
§ 9.16.110 Objectives, generally.
A.
Project design and layout shape the overall character of a project and how that project fits into its surroundings. New development should harmonize with the character of the adjacent area, implementing the general plan's design policies.
B.
The Moreno Valley general plan stresses variety in building design and compatibility with surrounding and planned land uses. Architectural treatment can address both, providing varied and sensitive building massing, consistent detailing and compatible building materials and styles. The following guidelines should help to achieve the level of quality, variety and compatibility of architectural design that the general plan requires.
C.
Site design and architectural guidelines have several objectives; among these are:
1.
Orienting buildings, parking and public spaces to enhance the streetscape, to add variety and to provide for pedestrian spaces and circulation;
2.
Translating design principles into architecture and site planning applications;
3.
Awakening an interest in urban design and form for Moreno Valley by requiring projects to be reviewed in their context;
4.
Reminding project developers of design considerations not usually covered by zoning development standards or design review;
5.
Using site planning techniques and architecture to provide for human scale;
6.
Providing for conservation of natural resources through building orientation, site amenities and architectural treatment, including water quality features integrated into the site design such as water retention and absorption areas and the use of pervious surfaces to reduce water run-off;
7.
Working in concert with the city's landscape requirements.
(Ord. 359 (Attach. 2), 1992; Ord. 826 § 3.6, 2011)
§ 9.16.120 General guidelines.
A.
General guidelines apply to all uses and projects citywide.
1.
The setback from streets and adjacent properties should relate to the scale of the proposed structure. Larger structures require more setback area for a balance of scale and compatibility with adjacent uses.
2.
Tall buildings should be made less imposing by stepping upper floors back from the first floor façade plane.
3.
Gateway treatments range in scale, identifying an entrance to the city, subcommunity, development project or a single building. Gateways, including enriched paving, raised medians, signs and other features as appropriate, create a sense of entry and should be included in all developments.
4.
New developments should respect the view of existing developments. Large developments should maintain view corridors which are oriented toward an existing or proposed amenity such as a park, open space or natural feature.
5.
Trash enclosures, loading areas, mechanical equipment and outdoor storage areas shall be screened from public view. Enclosures shall be compatible with the project architecture and shall not detract from the overall design theme.
6.
New residential flag lots shall be permitted only in hillside subdivisions and only when no other alternatives are available.
7.
Natural drainage courses should be retained in their natural state.
8.
Building mass and scale should be in proper proportion to the site, open spaces, street location and surrounding developments.
9.
All exterior wall elevations of buildings and screen walls shall have architectural treatments enhancing the building appearance. Uniform materials and consistent style should be evident in all exterior elevations of a building. Secondary materials should be used to highlight building features and to provide visual interest.
10.
Building massing should be varied to provide interesting form, proportion and scale. Monolithic forms are discouraged; massing variety should be three dimensional.
11.
Building design and siting should be compatible with surrounding land uses and with the climate and physical setting of Southern California.
12.
Building architecture should be compatible with surrounding existing or planned architectural character. Within commercial centers, materials, textures, colors and architectural detailing shall be compatible with the center's specified design theme.
13.
Shadow patterns created by architectural elements such as overhangs, projections and recesses of stories, balconies, reveals and awnings are encouraged, adding to building interest and aiding in climate control.
14.
Multi-story buildings should be detailed to reduce their vertical appearance as much as possible. This can be done by articulating the separate floor levels with horizontal bands, by increasing the level of detail on lower floors, by progressively lessening building mass on upper floors and by using heavier materials on lower floor façades.
15.
Building entries should be articulated through massing treatment and should incorporate detailed design elements.
16.
Roofs should be designed to be attractive when viewed from adjacent buildings or roadways. Roof-mounted equipment shall be concealed from public view. Roof drains shall be integrated into the building design and convey water to landscape areas for aesthetics and water quality.
17.
Base walls and other large expanses should be light colored. Soft tones ranging from white to very light pastels are encouraged. Natural light colors, such as off-whites, beige and sand, are also acceptable.
18.
Building accent elements, like doors, window framing, chimneys, trim, railing, awnings and light fixtures, should contrast with the main building color, producing added interest and a lively streetscape. Care should be taken not to use too many bright colors or too many different types of details to avoid an overwhelming or cluttered building.
19.
The use of simple color schemes using no more than three colors is recommended.
20.
All paint products, awning fabric or other color elements should be durable and fade resistant and shall be recommended by the manufacturer for the proposed use and location.
21.
The use of bright colors such as fluorescent, hot or "day glo" colors is strongly discouraged.
22.
Using building materials in their natural state is strongly recommended.
23.
Bricks should be left unpainted.
24.
Colors should be used to express identity and individuality within a cohesive and attractive framework.
25.
To facilitate compatibility in massing and scale, two-story buildings adjacent to one-story buildings should contain a one-story element or intermediate roof treatment or have an appropriate setback from the one-story building.

(Ord. 359 (Attach. 2), 1992; Ord. 456 §§ 1.1, 1.2, 1995; Ord. 604 § 2.21, 2002; Ord. 826 § 3.6, 2011)
§ 9.16.130 Single-family residential.
A.
These guidelines deal with single-family residential (R1, R2, RA-2, R3, R5) areas as well as areas designated hillside residential (HR) and rural residential (RR). They strive to improve the quality of life for single-family housing residents, to ensure attractive single-family neighborhoods and to offer solutions to recurring design problems.
1.
R1: provides for and protects the rural lifestyle by having large residential lots and the keeping of large animals.
2.
R2: provides for suburban lifestyles on residential lots larger than commonly available in suburban subdivisions, and to allow residential developments in a rural atmosphere.
3.
RA-2: provides for suburban lifestyles on residential lots larger than commonly available in suburban subdivision, and for the keeping of animals that have historically characterized these areas.
4.
R3: provides for a transition between rural and urban density development areas and provides for suburban lifestyle on residential lots larger than those commonly found in suburban subdivisions.
5.
R5: provides for single-family detached housing on common-sized suburban lots.
6.
Hillside residential (HR): balances the preservation of hillside areas with the development of view-oriented residential uses. These include large lot residential, and single-family residential on lots larger than 20,000 square feet.
7.
Rural residential (RR): provides for the protection of the rural lifestyles, as well as protects natural resources and hillsides in the rural portions of the city. Within the rural residential area large residential lots are appropriate and the keeping of large animals shall be permitted.
Table 9.16.130A | |
|---|---|
Designation | Maximum Density |
Hillside Residential | Depends on slope |
Rural Residential | Depends on slope |
R1 | 1 unit/acre |
R2 | 2 units/acre |
RA-2 | 2 units/acre |
R3 | 3 units/acre |
R5 | 5 units/acre |

5.
Increased setbacks shall be provided on lots that are sited at corners or have rear yards bordering an arterial roadway.
6.
Home builders shall consider the after-market construction of patio covers; room additions or second-floor balconies by providing ample rear yard setbacks. Rear yards shall be designed with minimum of 15 feet of flat areas adjacent to the structure.
7.
Residential projects should maximize the feeling of openness by curving streets, varying front and side yard setbacks and, if possible, orienting roads to open space areas and views.
8.
Small lot single-family subdivisions should utilize innovative design techniques to provide more usable and private exterior area.
9.
Residential mechanical equipment, including but not limited to air-conditioning units, shall be screened with walls and landscaping from surrounding properties and streets and shall not be located in the required front yard or street side yard.
10.
Storage of recreational vehicles, boats and campers should be provided for residents by either an enlarged side yard setback to allow access to the rear yard or an off-site storage area, both of which are to be out of public view. Residential units should be designed with the larger side yard, a minimum of 10 feet, on the garage side of the structure for storage/yard access. Pervious surfaces are required for such areas within required setbacks.
11.
Driveways shall be placed to maximize off-street parking opportunities and still maintain minimum landscape requirements. Pervious surfaces are recommended where feasible.
12.
Mailboxes, if required to be clustered, shall be designed to be compatible with surrounding homes, while conforming to post office guidelines.
13.
Property lines shall be located on the tops of slopes.
14.
Natural topographic variations should be retained to divide residential developments into distinct neighborhood areas.
15.
Within individual residential projects, a variety of floor plans and elevations should be offered as follows:
Table 9.16.130B | ||
|---|---|---|
Number of Units | Minimum # of Footprints | Minimum # of Elevations/ Footprints |
5—9 | 1 | 2 |
10—24 | 2 | 3 |
25—49 | 3 | 3 |
50 plus | Add one additional footprint for every 50 units over 50 | 4 |
Each floor plan shall not be repeated more than each fourth house. Please note that adding or deleting false shutters or similar types of minimal elevation changes will not suffice as one of the required distinct elevations.
16.
To minimize visual impact, corner residential units shall be single story or if two story, shall incorporate single story elements into the design. The short and low side of the unit should be sited toward the street corner.
17.
Automatic garage door openers shall be required to be installed in houses with less than a 20 foot front setback. Garage doors with windows shall be required for three or more car garages or other architecturally enhanced garage doors or as approved by the community development director.
18.

(Ord. 359 (Attach. 2), 1992; Ord. 398 § 2.2, 1993; Ord. 426 § 3.1, 1994; Ord. 604 § 2.4, 2002; Ord. 817 § 3.5, 2010; Ord. 826 § 3.6, 2011)
§ 9.16.150 Commercial (retail, office, mixed use).
A.
Commercial design guidelines address the various types and intensities of commercial uses allowed for in the general plan. They include neighborhood commercial, community commercial, tourist recreational commercial, village commercial, office commercial and office.
1.
Neighborhood Commercial: provides for the daily shopping needs of area residents with a wide range of common retail and personal service needs.
2.
Community Commercial: more intense than neighborhood commercial, provides for the general shopping needs of area residents and workers with a wide variety of retail and personal services.
3.
Tourist Recreational Commercial: provides those commercial support activities that are necessary or incidental to recreation uses while meeting the personal service needs of both tourists and city residents alike.
4.
Village Commercial: provides for office-related and commercial development within the Moreno townsite. It is the further intent of this designation to promote development which recognizes the historic significance of the site and projects a "turn-of-the-century" architectural atmosphere, yet provides limited retail commercial services that are compatible with the surrounding residential community.
B.
General Guidelines.
1.
Commercial development shall be compatible with adjacent residential areas by incorporating landscape buffers planted with a mix of flowering, screening and spreading plants, by using low mass, low height building elements, by locating loading and trash collection areas away from residential property lines and by directing circulation away from residential neighborhoods.
2.
Commercial development shall have a central place, main focal feature or point of emphasis, including pedestrian seating, shade structures, sculpture, water elements, centralized outdoor dining or any combination of these elements.
3.
New development should respect pedestrian needs by incorporating pedestrian ways and plazas that provide visual interest at the street level, shelter from the elements and adequate street furniture. This guideline is intended to enhance pedestrian related features in concert with quality architecture that would not require variance approval if incorporated as a feature of design.
4.
The development of new, small convenience centers on sites less than eight acres is discouraged.
5.
Architectural elements shall be an integral part of the façade design, avoiding the "pastedon" look.
6.
Building façades should relate to overhangs, awnings, trellises and porticoes, incorporating these elements into building massing.
7.
Pedestrian covered walks should have a clear walking width of seven feet along retail storefronts. Walkway width may be up to 12 feet to accommodate columns, furniture or building articulation.
8.
Large structures shall incorporate varied setbacks and variations in massing of building bulk.
9.
Continuous, blank building elevations shall be avoided, particularly when visible from public rights-of-way.
10.
Continuous building mass should be divided into smaller units, providing both variety and scale.
11.
Loading areas shall be oriented away from street side elevations whenever possible and shall be screened from public view with a combination of walls and landscaping.
12.
Building placement within office developments shall occur at or near the street setback line to bring the architectural image to the street and to remove parking lots to the extent possible from the streetscape.
13.
Vehicular and pedestrian travel shall be separated to the best possible extent, providing for a safe pedestrian environment and smooth traffic flow.
14.
Pedestrian walkways shall be provided in larger parking lots, encouraging foot travel out of vehicular drive lanes.
15.
Freestanding or clustered retail, restaurant and office pads are encouraged, helping to add variety to the site plan and to introduce interesting architectural elements.
16.
Interparcel access shall be provided between commercial centers, reducing the number of drive approaches from the street and encouraging commercial "crossover."
17.
Entry drive throats shall be at least 60 feet long from property line for major commercial projects, providing adequate queuing for outbound traffic and smoothing inbound traffic flow.
18.
Each commercial center of five acres or more shall have at least one major entry containing a median.
19.
The "strip" commercial image is discouraged. New development should provide variety and articulation in storefront footprints, elevations and roofline.
20.
There shall be a landscaped strip equal to the building height where a commercial use is located adjacent to residentially zoned property.
21.
Office developments shall provide courtyards for each building convenient to office users, incorporating seating, sculpture, accent landscaping and shelter. These shelters will allow for small lunch gatherings or relaxation.
22.
Office developments shall have decentralized parking. Parking shall be oriented to the building it is intended to serve and shall be spread throughout the site, lessening the impact of an expansive parking lot.
23.
Office developments shall offer interesting site plans by providing several detached or clustered buildings.
24.
Access to service bays of automotive uses shall be from the interior of the site.
25.
Service stations, mini markets and other automobile-related uses shall have architectural details consistent with the overall project design. Access to service bays will be from the interior of the service station site. Window placement should be sensitive to casual police surveillance.
26.
Hotels four stories and over shall include rooftop amenities (e.g., restaurant, bar, swimming pool or other amenities as accepted by the community development director).
27.
Freestanding buildings should incorporate distinctive massing, adding interest to the site and vicinity.
28.
Intimate scale in building design and materials selection is encouraged, emphasizing comfort and warmth.
29.
All rooftop equipment shall be part of the project design or be screened and located out of view from the pedestrian level, public rights-of-way, adjacent freeways and neighboring structures. Flat-roof drainage pipes shall be integrated into the project design and drain into a landscape area for water quality, retention and absorption to reduce water runoff.
30.
Architectural design of new projects shall be mindful of the surrounding district's urban fabric, providing a design statement to enhance the context and to upgrade the overall image.

§ 9.16.170 Generally.
Hillside development can offer opportunities for spectacular views from building sites around the valley's perimeter. It is important, however, to ensure that all are protected when designing hillside building sites. The guidelines in this section apply to the hillside areas illustrated in the general plan and official zoning atlas. Applicant's compliance with this chapter shall be reviewed during the planning application review process for any entitlements subject to this chapter. No separate planning application or fee is required for hillside development projects.
§ 9.16.180 General guidelines.
A.
All general grading guidelines and standards shall apply to hillside development unless modified by this chapter.
1.
Where the average slope exceeds 25%, a geology report assessing rock slide potential shall be submitted to the planning division at the time of submittal of the project to the city. The report shall be approved by the city engineer prior to planning commission approval.
2.
Prior to the submittal of a project application where the average slope exceeds 10%, the applicant should call for a preapplication meeting to discuss city concerns and requirements regarding the proposed hillside development.

§ 9.16.210 Grading.
A.
Man-made slopes shall conform to patterns of the natural terrain. All cut and fill slopes shall be landscaped and shall be stabilized to control erosion.
B.
"Landforming" shall be applied to all slopes adjacent to public streets, gateways, and public view areas, as well as to all slopes greater than 100 feet in length or 10 feet in vertical height.
1.
Landforming shall be accomplished by the use of variable slope ratios, undulating of tops and toes, screening of terraces and downdrains, varying of surface features, and by landscaping.
2.
Rear and side yard slopes between adjacent lots within the same project need not be landformed unless they are greater than 100 feet in length or 10 feet in vertical height.
C.
Any cut or fill slope to be revegetated shall not be steeper than 2:1.
D.
All excess excavated material shall be removed or otherwise placed to become an integral part of the site development.
E.
During construction, measures such as sediment traps or terracing shall be used around all graded areas to minimize erosion.
F.
Whenever archeological or paleontological sites are discovered during excavation, the planning division shall be notified immediately and mutually agreeable precautions taken to preserve the artifacts.
G.
Natural features such as trees with four-inch or larger trunk diameters and significant rock outcroppings shall be protected to the greatest extent feasible in the siting of individual lots and building pads. These features shall be shown on the grading plan with appropriate protection and relocation notes. Where trees with four-inch or greater trunk diameters are to be removed, they shall be replaced with at least 24 inch box size trees of the same species, or as approved by the planning division, at a ratio of three new trees for each mature tree removed.
H.
All dwelling units shall be located a minimum of 10 feet from the tops and toes of all slopes, unless otherwise approved by the city engineer and the community development department.
I.
Crib walls, or an equivalent, may be used to enhance a cut slope's capability to be landscaped, providing they are properly irrigated. They should not be used, however, to increase flat pad size or to otherwise intensify project grading.
J.
Any manufactured slope shall be contoured in a manner to appear to have a natural grade.

§ 9.16.220 Roadways and circulation.
A.
Road alignments, driveways and parking areas shall conform as closely as possible to natural topography.
B.
Existing vegetation shall be preserved to the greatest extent possible in the location of roads and shall be retained as medians or buffers wherever possible within the unimproved right-of-way.
C.
Variations in road design and construction may be permitted to keep grading and cut slopes to a minimum.
D.
One-way loop roads may be constructed where appropriate for the terrain.
E.
Combinations of collective private driveways, cluster parking areas and off-street parking bays (including pervious paving where feasible) are encouraged to minimize paved areas.

§ 9.16.235 Hillside design standards.
A.
Site Plan Design. Each structure shall be located in the most accessible, least visually prominent, most geologically stable portion or portions of the site, and at the lowest feasible elevation. Structures shall also be aligned with the natural contours of the site. Locating structures in the least prominent locations is particularly important on open hillsides where the high visibility of construction should be minimized by placing structures so that they will be screened by existing vegetation, depressions in topography, or other natural features. In addition, the following standards shall apply:
1.
Significantly visible rock outcroppings should be preserved and incorporated into the site plan.
2.
All pads and driveways shall, to the fullest extent practicable, follow and utilize the natural contours of the land to minimize disturbance and shall not be located on the crest of a natural ridgeline.
3.
Clustering of development on flatter areas of the site is strongly encouraged.
4.
Dwelling units and structures shall be sited in a manner that will:
5.
In areas adjacent to a ridgeline or in moderate slope areas, dwelling units and structures shall be sited to:
a.
Use the natural ridgeline as a backdrop for structures;
b.
Use landscape plant materials as a backdrop;
c.
Use the structure to conceal cut slopes;
d.
Retain major natural skyline profiles;
e.
The topmost point of a proposed structure and all site grading shall be at least 30 feet below the top of the nearest ridge or knoll.
6.
Encourage smaller pad to lot size ratios for all dwelling units.
7.
Streets, both public and private, shall be developed below the crest of a natural ridgeline.
B.
Architectural Design. The following architectural design standards shall apply:
1.
Building development color palettes, including roofing, fencing and exterior building materials, shall be "earth tones" compatible with the natural color of the terrain and vegetation, and shall be approved by the community development director.
2.
The design of the structure should give consideration to the lot's size and configuration in order to avoid the appearance of overbuilding and to minimize the blocking of views.
3.
Large expanses of a single material on walls, roofs or paving areas should be avoided. Create interesting small scale patterns by breaking up building mass, varying building materials, etc. Building plans and elevations should be varied throughout a development to avoid a monotonous "cookie-cutter" look.
4.
Horizontal and vertical architecture detailing of building articulation, such as overhangs, projections, alcoves, varied roof-plains, building offsets, etc., should be used to avoid large expanses of a wall in a single plane and to create light and shadow.
5.
Brightly colored structures and roofs and reflective glass or building materials are expressly prohibited. Materials and colors shall blend with the natural hillside environment to the greatest degree feasible. Specific materials that are encouraged are those with natural colors and textures, including stone, wood, textured stucco and brick.
6.
Where it will not result in increased grading and landform alteration, the limitation of structures to a single story is strongly encouraged.
7.
The use of undulating walls that follow the land form are highly encouraged.
8.
Detaching the garage shall be encouraged, while retaining walls shall be integrated into the garage walls on sloping lots to reduce grading and minimize visibility of walls.
9.
Include architectural enrichments and variations in roof massing. Roofs should have low profiles to minimize their visual impact. On sloping land, the roof pitch should follow the slope of the hillside, instead of being perpendicular to the hillside or opposing hillside slope. Upper stories should not be cantilevered out of the opposite direction of the hillside slope.
C.
Lighting Design. The intent of lighting standards for designated hillside properties is to preserve the low light level conditions that are inherently characteristic of hillside areas. The following lighting design standards shall apply:
1.
Lights shall not be located on the portion(s) of the site that has not been disturbed.
2.
Lights mounted on dwellings, buildings or structures shall be fully shielded and directed away from adjacent developments.
3.
All light fixtures should be directed downward and properly aimed on the targeted areas to maximize their effectiveness and minimize the total number of light fixtures.
4.
All lighting shall be low scale and low intensity and directed downward and away from the view of others.
5.
Road, driveway and walkway lights should be located on the "downhill" side and aimed toward the "uphill" side and should be fully shielded from below and only light the driveway surface.
6.
Lighting fixtures on properties should be mounted on a post not to exceed a height of eight feet above finished grade, or on a building wall not to exceed a height of eight feet above finished grade and fully shielded, or on a structure not to exceed a height of eight feet above finished grade and fully shielded for security lighting.
7.
Street lighting shall be limited to the greatest degree feasible to maintain a "dark sky" environment. Typically, streetlights should be limited to street intersections or other locations where safety concerns predicate the need for illumination.
(Ord. 773 § 3, 2008; Ord. 826 § 3.6, 2011; Ord. 851 § 1.3, 2012)
§ 9.16.270 General requirements.
A.
Signs are one of the most prominent visual elements of the street. If well designed, signs can add interest and variety to a building's façade and the overall street scene. A well-designed sign can say a lot about a business. A poorly designed sign, however, can detract from even the most attractive storefront, cluttering the façade and disturbing views.
B.
These guidelines address sign design, working in concert with the city's sign ordinance and suggesting design techniques to produce signs that successfully promote businesses while tastefully contributing to Moreno Valley's image.
1.
Signs shall be visible and legible, but not large and flashy.
2.
Messages should be direct and simple, using graphic symbols or simple verbal messages.
3.
Sign materials and design should harmonize with the building's architecture, incorporating similar details and colors.
4.
The overall size and shape of a sign should not detract from its message. Letters should not occupy more than 75% of the permitted sign face area for a tenant's wall sign.
5.
Master sign programs are required for large retail, office and industrial centers, distributing sign area among the individual store fronts in proportion to the frontage length of each and specifying letter styles, sign colors, wall sign locations, ground sign locations, and types and sizes of other permitted signs.
6.
Monument signs should be landscaped to help integrate the sign into the site. Landscaping should build up to the sign, becoming an integral part and adding emphasis to the sign while making it appear more natural.
7.
One-sided monument signs should incorporate earth berms behind them, helping to blend the sign into the landscape.
8.
Monument sign landscaping should encircle the sign, softening the sign's edges on all sides.
9.
Monument signs should be unique and should avoid an overall rectangular shape incorporating architectural elements and themes of buildings being identified.
10.
Monument signs shall be located away from telephone poles, utility boxes, transformers, streetlights or any other obstacle that might impair their visibility.
11.
Night lighting of signs shall not be obtrusive, avoiding spilling light or glare onto adjacent properties or right-of-way. Signs may be illuminated in a number of ways, with reverse channel illumination having the least disruptive impact.
12.
When possible, monument signs shall incorporate planters or climbing vines in their design.
13.
Ground-mounted lighting fixtures for indirect sign illumination shall be fully concealed by berming and landscaping, minimizing light spillover and enhancing sign aesthetics.
14.
Wall signs should be composed of either individual channel letters or reverse channel letters. No raceways shall be exposed. Can signs are discouraged.
15.
Imaginative designs departing from the traditional methods and placements are encouraged, but they shall not endanger public health, safety or general welfare.
16.
Temporary signs shall not be located in public rights-of-way, in streetside landscape areas or in required parking spaces and shall, in all ways, comply with appropriate provisions of the city's sign ordinance.
17.
Modified monument signs shall display a maximum of six tenant panels.
 Monument Sign Built Into Slope |
 Signs Deviating from a Strictly Rectangular Shape |

§ 9.16.280 General requirements.
A.
Purpose and Intent. Lighting shall serves both safety and aesthetic purposes, while reducing unnecessary light pollution and maintaining dark skies. Effective lighting will highlight building features and add emphasis to important spaces and entryways, while limiting glare and light trespass onto adjacent properties. The intent of these guidelines is to encourage effective and innovative lighting as an integral design component of a project.
B.
General Guidelines.
1.
Exterior lighting should relate to the design the project, highlighting architectural elements and details without deflecting unnecessary light and glare onto surrounding properties.
2.
Lighting should improve the visual identification of residences and businesses.
3.
Energy efficient lighting of buildings is encouraged.
4.
High-intensity security lighting fixtures should be concealed by landscaping or building architectural elements.
5.
The location, color and intensity of private lighting should relate to and complement public lighting.
6.
Lighting fixture design should complement the overall design theme of the project in which they are located.
7.
At hazardous locations such as changes of grade, low level supplemental lighting units should be used.
8.
Where low level lighting (below five feet) is used, fixtures should be placed so that they do not produce glare.
