The following standards shall apply to land and permitted or conditionally permitted buildings and structures located within the herein described residential districts. The standards stated herein are not intended to prevent more restrictive private site development standards contained in the covenants, conditions and restrictions or other private consensual restrictions imposed on any property or dwelling unit. However, in no case shall private deed or other property restrictions be applied or recognized so as to permit a lesser standard than the minimum standards established in this title or to otherwise revise the standards established by this title.
A. Rural Residential Requirements.
1. Slope-Density-Natural Area Relationship. The maximum density (du/ac) and the minimum percent of a site to remain in a natural state shall be determined by a slope analysis applied to the Slope-Density-Natural Area Table, as defined below.
a. Slope-Density-Natural Area Table 9.03.040-4.
Slope Class | Allowable Density (DU/Acre) | Amount of Open Space Required |
|---|
Greater than 25% | 0.05 (1 du/20 ac) | 60% |
15.1% to 25% | 0.10 (1 du/10 ac) | 50% |
10% to 15% | 0.20 (1 du/5 ac) | 35% |
Less than 10% | 0.40 (1 du/2.5 ac) | n/a |
b. Slope analysis calculations and mapping shall be provided by the applicant as described under subsection
C of this section. The slope analysis shall be certified by a qualified civil engineer or licensed surveyor.
c. The total number of dwelling units permitted within a project area shall be the sum of the allowable dwelling units within each slope class. For example, if 10 acres of the project falls within the 10 to 15% slope class and five acres falls within the 15.1% to 25% slope class, then the total permitted yield shall be two dwelling units (10 ac x 0.10 du/ac plus 5 ac x 0.20 du/ac).
2. Minimum Lot Size. Minimum lot size shall be one dwelling unit per two and one-half acres within a slope category of 10% or less unless determined to be reduced by an approved slope analysis. Based on the outcome of a slope analysis, minimum lot size within the rural residential district may be reduced to 20,000 square feet, or the minimum lot size of the adjacent zone, whichever is greater, if clustered on slopes of less than 10% and the lots are part of a project that preserves the steeper slope classes as natural open space by dedication to an appropriate governmental entity, open space easement, transfer of development rights or other means approved by the city. The ongoing maintenance of such open space areas shall be ensured through a mechanism approved by the city.
3. Subdivision Design and Future Land Divisions.
a. Subdivisions shall be compatible with the surrounding development pattern. A subdivision shall be considered compatible if the lots created along the outside boundary of the project are no smaller than the average lot size within 300 feet of the project boundary. Parcels greater than five acres in area shall be excluded from the calculations when determining the average lot size within 300 feet of the project boundary.
b. Subdivisions shall be designed in such a way as to transfer development density to the lower slope classes and preserve the steeper slopes for very low density and/or open space. Subdivisions created in this way are prohibited from further division so as not to circumvent the density transfer and the purpose of the district. This restriction shall be binding on the subdivider and subsequent land owners. Therefore, this restriction shall be secured by development agreement or other type of recorded deed restriction approved by the city.
4. Building Height. Dwellings and other accessory structures shall not exceed 30 feet in overall height, provided that on slopes of less than 10%, the overall height shall not exceed 35 feet.
5. Setbacks and Other Site Development Criteria. Front, side and rear setbacks and other site development standards not specifically referenced in this section shall be subject to the following standards:
Lot Size | Standards |
|---|
Under 40,000 s.f. | R2 district standards |
40,000 s.f. or greater | R1 district standards |
6. Grading within the rural residential district shall be performed as described under the hillside residential requirements, subsection (B)(6) of this section.
B. Hillside Residential Requirements.
1. Slope-Density-Natural Area Relationship. The maximum density (du/ac) and the percent of a site to remain in a natural state shall be determined by a slope analysis applied to the Slope-Density-Natural Area Table, as defined below.
a. Slope-Density-Natural Area Table 9.03.040-5.
Slope Class | Allowable Density (DU/Acre) | Minimum Amount of Open Space Required |
|---|
Greater than 25% | 0.10 (1 du/10 ac) | 60% |
15.1% to 25% | 0.25 (1 du/4 ac) | 50% |
10% to 15% | 0.50 (1 du/2 ac) | 35% |
Less than 10% | 1.00 (1 du/ac) | n/a |
b. Slope analysis calculations and mapping shall be provided by the applicant as described under subsection
C of this section. The community development director may require the slope analysis to be certified by a qualified civil engineer or licensed surveyor.
c. The total number of dwelling units permitted within a project area shall be the sum of the allowable dwelling units within each slope class. For example, if 10 acres of the project falls within the 15.1% to 25% slope class and five acres falls within the greater than 25% slope class, then the total permitted yield shall be three dwelling units (10 ac x 0.25 du/ac plus 5 ac x 0.10 du/ac).
2. Minimum Lot Size. Minimum lot size shall be one acre within a slope category of 10% or less unless determined to be reduced by an approved slope analysis. Based on the outcome of a slope analysis, the lot size within the hillside residential district may be reduced to 10,000 square feet or the minimum lot size of the adjacent zone, whichever is greater, if clustered on slopes of less than 10% and the lots are part of a project that preserves the steeper slope classes as natural open space by dedication to an appropriate governmental entity, open space easement, transfer of development rights or other means approved by the city. The ongoing maintenance of such open space areas shall be ensured through a mechanism approved by the city.
3. Subdivision Design and Future Land Divisions.
a. Subdivisions shall be compatible with the surrounding development pattern. A subdivision shall be considered compatible if the lots created along the outside boundary of the project are no smaller than the average lot size within 300 feet of the project boundary. Parcels greater than five acres in area shall be excluded from the calculations when determining the average lot size within 300 feet of the project boundary.
b. Subdivisions shall be designed in such a way as to transfer development density to the lower slope classes and preserve the steeper slopes for very low density and/or open space. Subdivisions created in this way are prohibited from further division so as not to circumvent the density transfer and the purpose of the district. This restriction shall be binding on the subdivider and subsequent land owners. Therefore, this restriction shall be secured by development agreement or other type of recorded deed restriction approved by the city.
4. Building Height. Dwellings and other accessory structures shall not exceed 30 feet in overall height, provided that on slopes of less than 10%, the overall height shall not exceed 35 feet.
5. Setbacks and Other Site Development Criteria. Front, side and rear setbacks and other site development standards not specifically referenced in this section shall be subject to the following standards:
Lot Size | Standards |
|---|
Less than 20,000 s.f. | R-3 district standards |
20,000 s.f. to 40,000 s.f. | R-2 district standards |
40,000 s.f. or greater | R-1 district standards |
6. Grading of any site shall be minimized and shall conform to the provisions contained in the city of Moreno Valley design guidelines, Ch.
9.16, under applications for hillside development, Article
IV, Sections
9.16.170 through
9.16.235 of this title, and the following standards:
Slope Class | Standards |
|---|
15.1—25% | Padded building sites may be allowed, but maximum use of custom foundations and split level designs shall be employed to reduce the need for large, padded building areas. |
Above 25% | Mass grading is not permitted. Special hillside architectural and design techniques are expected in order to conform to the natural landform. Homes constructed on lots within this terrain shall use custom, multiple-level foundations. |
For all areas | All graded areas shall be protected from wind and water erosion through acceptable slope stabilization methods such as planting, walls or jute netting. |
C. Slope Calculations. For the purposes of this section, the following method will be used to determine slope.
1. "Slope" is defined as the relationship between the change in elevation (rise) of the land and the horizontal distance (run) over which that change in elevation occurs. The percent of any given slope is determined by dividing the rise by the run on the natural slope of land, multiplied by 100.
2.
a. For the purpose of determining the amount and location of land falling into each slope category, the applicant shall submit to the community development department, at the time of application, a base topographic map of the subject site prepared and signed by a registered civil engineer or licensed land surveyor. Such a map shall have a scale of not less than one inch to 200 feet and a contour interval of not more than 10 feet.
b. This base topographic map shall include all adjoining properties within 300 feet of the site boundaries. Slope bands in the range of less than 10%, 10 to 15%, 15 to 25%, and greater than 25% shall be delineated on the topographic map. The map shall be accompanied by a tabulation of the land area in each slope category specified in acres. The exact method for computing the percent slope and area by percent slope category is to be sufficiently described and presented so that a review can readily be made.
3. Slope Mapping Method.
a. The percent slope of any particular piece of land shall be plotted on the map as described in this subsection.
b. In preparing a slope map, those portions of ravines, ridges and terraces of less area generally sloping at 25% slope or greater, shall be regarded as part of the bordering 25% slope or greater band.
D. General Residential Requirements. The following tables sets forth minimum site development standards for residential development projects in the specified residential districts. In addition, projects must comply with the special development standards enumerated in this section, the performance standards included in Chapter
9.10 and any other applicable city ordinances, policies and standards.

1. In any residential district, front yard setbacks in subdivision developments may be reduced by 20% provided the mean of all such setbacks in the development is not less than the minimum required for the district.
2. In the R2, RA2, R3 and R5 districts, developments of five or more dwelling units shall include front and street side yard landscaping and shall consist predominantly of plant materials, except for necessary walks, drives and fences.
3. In the RS10 district, driveways and fire hydrants shall be designed and located to maximize on-street parking opportunities in front of each residence.
4. Within the RS10 district, small lot single-family subdivisions on less than 15 gross acres shall provide landscaping and decorative walls along the street side of corner lots and at least two of the following amenities throughout the project:
b. Automatic garage door openers;
c. Electronic security systems.
5. Within the RS10 district, small lot single-family subdivisions on 15 gross acres or more shall include usable common open space encompassing a minimum of 10% of each development. Usable common open space does not include individually owned lots, parking areas, nor vehicular rights-of-way. Usable common open space is open space and/or recreational amenities under joint (common) ownership, including, but not necessarily limited to, landscaped areas, trails, playgrounds, tennis courts, swimming pools and recreational buildings. A homeowners' association shall be established to provide continual maintenance of the commonly owned facilities.
6. For all developments within the R5 land use district, a buffer of lots held to the development standards of the R3 land use district shall be included for all portions of a subdivision located adjacent to lower density single-family residential land use districts, including the R1, R2, RA-2, and RR zones.
7. For all single-family residential developments in the R10, R15, R20, and R30 districts a planned unit development application shall be submitted to establish the applicable development standards.
8. In all residential districts, air conditioners, heating, cooling and ventilating equipment and all other mechanical, lighting or electrical devices shall be operated so that noise levels do not exceed 60 dBA (Ldn) at the property line.

5. In the RS10, R10, R15, R20 and R30 districts, a minimum of 35% of the net site area, exclusive of private patio and yard areas, shall be landscaped. Turf shall not exceed 50% of this area. Required setback areas and outdoor recreation areas may be counted toward this minimum. Landscaping shall consist predominately of plant materials to include water efficient native plants, except for necessary walks and fences. Landscape areas shall be designed to promote water retention and allow runoff from impervious surfaces. Hardscape areas are recommended to be constructed with pervious surfaces where feasible to reduce run off.
6. Where a multiple-family project abuts property in a single-family district, a decorative masonry wall at least six feet in height and screening landscaping within a planter of at least five-foot interior width shall be erected and maintained between such uses and the single-family district. Decorative walls composed of block, brick, stone, stucco-treated masonry or concrete panels are acceptable. The community development director may approve alternative materials, provided that the materials are decorative and comparable to masonry walls or concrete panels in durability and ability to attenuate light and sound.
7. Parking for each use shall comply with the requirements of Chapter
9.11 of this title.
8. In the R30 District, Landscape Trees. One tree per 20 linear feet of building dimension for the portions of building visible from parking lot or ROW and one tree per 20 linear feet of perimeter planter areas.

G. General Multiple-Family Guidelines.
1. Opposing garages or carports should be turned to avoid the monotony of alley-like parking corridors.
2. Parking areas should be staggered and landscaped to add visual interest, and opportunities for accent treatments.
3. Parking spaces within multifamily areas shall be located within 250 feet of the dwellings they serve.
4. Multifamily parking lots shall be limited to two double aisles of cars to help reduce expanses of paving. Parking lots shall provide openings in curbs to convey surface drainage into landscape areas for water quality, retention and absorption.
5. Open parking areas should be clustered and treated as landscaped plazas and courts.
6. Landscaping shall be used around the perimeter of the lot, as well as within the lot, reducing paved area and providing for a more pedestrian oriented site.
7. No more than four units for a two-story structure should be served by one entry.
8. Each multiple-family unit shall have at least 150 square feet of private open space per downstairs unit and a minimum of 100 square feet of private open space per upstairs unit. Private open space may consist of a fenced yard area, patio or balcony. Fenced yards and patios shall have a minimum dimension of at least eight feet. Balconies shall be at least five feet deep.
9. Common open space at a minimum of 300 square feet per each residential dwelling in the project is required.
10. Individual units should have a porch or porch-like space at the front door.
11. Trash enclosures shall be located to provide a maximum walking distance of 250 feet from the units they serve.
12. Trash enclosures shall include solid roofs and be designed to be compatible with the project's architecture.
13. Trash enclosures shall not be located on dead end drive aisles, unless adequate turnaround is provided for collection vehicles.
14. There shall be at least one double-bin trash enclosure for every 48 residential units.
15. Mail boxes should be located at various places on the site and treated to match the building's architecture, avoiding the institutional and monumental "gang box" appearance, while conforming to post office guidelines.
16. Drive aisles should be curved and should incorporate landscaping and paving treatments to reduce vehicle speed. Landscaping treatments may include pinched planters and a mix of canopy and vertical trees. Paving treatments may include interlocking paver bands or etchings across drives. Speed bumps or Botts' dots are not an acceptable alternative.
17. Freestanding structures, like gazebos or pergolas, should be located to define activity areas at pathway intersections or in secluded landscape areas.
18. Drive aisles shall be at least 24 feet wide for two-way traffic and shall be at least 20 feet wide for one-way traffic.
19. Buffer setbacks and landscaping shall be provided along all property lines. Buffers may also be appropriate within the complex, separating recreational areas from units and limiting lines of sight between balconies and into parking areas.
20. Multiple-family projects warrant special design considerations, including:
a. Intimate, shaded outdoor seating areas;
b. A network of pathways, providing interesting walking experiences;
c. Gentle slopes for outdoor pathways and ramps to entry doors and between floors;
d. Convenient and attractive access to transit, including porte cocheres, information kiosks, seating areas and water elements;
f. Direct ambulance access (senior housing projects);
h. Elevators (senior housing projects).
21. Multifamily units shall be clustered to minimize grading and to help maintain the natural landscape.
22. Multifamily projects shall be designed for the needs of the intended residents. For example, children's needs would require open space, tot lots, handrails, and enclosed yards on ground floor units. Disabled or elderly needs would require ramps, parking close to units, minimum and gradual elevation changes and elevators.
23. Architectural features should be used to increase privacy from nearby units and common or public spaces.
24. Roof forms should be mixed and combined to vary the perception of building height, to differentiate units and to add interest to building mass. The long, straight roofline of a single gable is not permitted.
25. A diagram of the complex showing the location of the viewer and the building designations shall be positioned at each visitor entrance of a multiple-family development.
26. Buildings shall provide for a variety of colors and architectural features to break up the massing of buildings and provide visual interest.
