Perris City Zoning Code

CHAPTER 19.86.

SENIOR HOUSING OVERLAY ZONE (SHO)

Sec. 19.86.010.- General.

Upon proper application, a senior housing overlay zone may be combined with any of the city's conventional residential or commercial zone districts. When the Senior Housing Overlay (SHO) Zone is shown on the city's zoning map, it shall be combined with one of the city's applicable conventional districts. For example, the application of SHO overlay in the R-10,000 zone shall be shown as "R-10,000-SHO." Any lot designated by the SHO Zone is subject to the land use and density/intensity provisions of the underlying zone district, except as provided herein. If provisions in the chapter differ from other provisions of this Code, including the development standards of the underlying zone, the provision of this chapter supersede and shall be applicable and controlling.

(Code 1972, § 19.86.010)

Sec. 19.86.020. - Purpose and intent.

(a)

Purpose.

(1)

To encourage the development of senior housing that is compatible and complementary to its neighborhood context, is located near essential services and amenities required by seniors, and allows for or encourages neighborhood walkability.

(2)

To provide various incentives which are consistent with the state density bonus for senior housing projects.

(3)

To ensure that adequate affordable housing is provided to very low and moderate income senior citizens consistent with the regional housing needs assessment (RHNA) dictated by the state department of housing and community development.

(4)

To facilitate the development of senior housing projects which are superior in functional design, quality of construction, appearance, and operational standards.

(5)

To ensure that the requirements of the Americans with Disabilities Act (ADA) and universal design principles are incorporated within senior housing developments.

(b)

Intent. This district is designed to provide for residential uses that are appropriate for the development of seniors, recognizing their unique lifestyles and needs, by allowing higher densities, a mix of uses, and requiring in return, higher design and construction standards, as well as the provision of specific site and building amenities. It is the intent of this zone to carry out the policies and objectives of all elements of the general plan and to meet the standards necessary to satisfy the requirements for public health, safety, and general welfare.

(Code 1972, § 19.86.070)

Sec. 19.86.080. - Development criteria.

(a)

Site character.

(1)

Structures that are historic or are otherwise distinctive because of their age, cultural significance, or unique architectural style should be preserved and incorporated into development proposals.

(2)

When a SHO project adjoining residential and commercial uses can mutually benefit from connection rather than separation, appropriate connective elements (e.g., walkways) should be provided.

(3)

Existing amenities (e.g., views, mature trees, etc.) that are unique to the site should be preserved and incorporated into the project's design whenever possible.

(b)

Site access. Developments with more than 200 parking stalls that are located on arterial highways should coordinate access points with median openings and existing driveways on the opposite side of the roadway. Such developments may also be required to provide deceleration lanes adjacent to their major entry.

(c)

Building setbacks.

(1)

Frontage. The building setback along all street frontages shall be equal to one-half the height of the building wall but in no case shall it be less than 20 feet.

(2)

All other property lines. All other setbacks shall be equal to the height of the building wall which fronts the subject property line. However, accessory structures such as garages, carports, and equipment enclosures may be located on the property line.

(d)

Building design layout.

(1)

The minimum dwelling size for each unit shall be as follows:

a.

Studio: 475 square feet.

b.

One bedroom: 525 square feet.

c.

Two bedroom: 700 square feet.

(2)

Multiple buildings in a single project should provide a functional relationship with one another to achieve a sense of place by use of the following techniques:

a.

Cluster buildings around open plaza areas or courtyards, not parking lots.

b.

Provide open plaza areas and courtyards with landscaping and other pedestrian amenities.

c.

Provide convenient pedestrian circulation between buildings, and open parking areas.

d.

Link buildings together visually using trellis structures, arcades, and enhanced paving.

e.

Where feasible, locate buildings near public streets, thus creating a strong presence thereon.

f.

If applicable, link development with adjacent compatible uses, such as shopping areas through the use of landscaped walkways.

(e)

Building and unit design. Universal design (also known as "aging in place") is a method of design that seeks to create development that can be used by everyone, regardless of age or physical condition. All projects shall implement, at minimum, the following universal design principles:

(1)

No-step entries.

(2)

One-story living such that an eating area, bathroom, and sleeping area are available on the same floor.

(3)

Front doors with a minimum width of 36 inches to accommodate the use of wheelchairs and 32-inch free-swing doors (34-inch door) on all interior doors.

(4)

Hallway minimum width of 42 inches to accommodate the use of wheelchairs.

(5)

Room thresholds that are flush.

(6)

Adequate lighting throughout the dwelling unit.

(7)

Provide lever door handles and rocker light switches.

(8)

Provide additional closet rod brackets to allow potential access from a wheelchair.

(9)

Wheelchair-accessible bathrooms. Provide adequate space for maneuverability and access to facilities to those using wheelchairs.

(f)

Architectural style. A common design style or a palette of architectural features is encouraged for each SHO project. A specific design style is not required; however, consistency within each project's materials and design features is required such that each development attain a unifying appearance.

(g)

SHO design guidelines.

(1)

Consistency.

a.

Building design should demonstrate a consistent use of colors, materials, and detailing throughout all elevations of the building. Piecemeal embellishment should be avoided.

b.

Elevations that do not directly face a street should not be ignored or receive only minimal architectural treatment. Each facade should be designed for public view and should be appropriately landscaped.

c.

Consistency in design shall also apply to all accessory structures and elements in the ground plane (hardscape and softscape).

(2)

Form and mass. Designs should provide a sense of human scale and proportion. Structures should be designed to avoid a "box-like," impersonal appearance by use of the following techniques:

a.

Facade articulation. Separations, changes in plane and height, and the inclusion of elements including balconies, porches, arcades, dormers, and cross gables mitigate the barracks-like quality of flat walls.

b.

Provide architectural detail through the use of columns, three-dimensional decorative cornice bands, recessed entries and windows, and awnings and canopies.

c.

Provide full roofs with substantial overhangs.

d.

Articulate roofs of excessive length. Secondary hipped or gabled roofs covering the entire mass of a building are preferable to flat roofs, mansard roofs, or pitched roof segments applied on only some portions of the building.

e.

Incorporate decorative parapets where roof overhangs are not provided that are deep enough to hide roof-mounted equipment.

f.

Structures containing three or more attached dwellings in a row should incorporate at least one architectural projection not less than two feet from the wall plane and not less than four feet wide.

(3)

Materials. Exterior materials should be very durable and require low maintenance. Piecemeal embellishment and frequent changes in materials should be avoided. Exterior wall colors should harmonize with the site and surrounding buildings. Natural surfaces such as stone and slate should be used as accents, especially at building entrances.

(4)

Colors.

a.

Facade colors should be neutral or earth tone colors. The use of high-intensity colors, metallic colors, black, or fluorescent colors is discouraged.

b.

Building trim and accent areas may feature brighter colors, including primary colors. However these colors must complement the facade colors.

c.

The transition between base and accent colors should relate to changes in building materials or the change of building surface planes. Colors should not meet or change without some physical change or definition to the surface plane.

d.

The blending of compatible colors in a single facade or composition is a good way to add character and variety, while reducing, or breaking up monotonous spans of a building.

e.

Unusual patterns and color schemes should be avoided.

f.

Color and finishes on building exteriors of all elevations of a building should be coordinated to provide a total continuity of design.

(5)

Entries should be protected from the elements. Entries add human scale and should create a focus and a clear sense of entry for the building by use of at least two of the following:

a.

Wall recesses.

b.

Roof overhangs.

c.

Canopies and awnings.

d.

Arcades.

e.

Oversized doors.

(6)

Balconies, porches, and patios. The incorporation of balconies, porches, and recessed patios is encouraged for both aesthetic value and for the practical provision of defined outdoor space. These elements should be integrated into structures to break up large wall masses, offset floor setbacks, and add human scale to buildings.

(7)

Dwelling unit access. The use of long, monotonous access balconies and/or corridors that provide access to five or more units should be avoided. Instead, access points to units should be clustered in groups of four or less. The use of distinctive architectural elements and materials to denote prominent entrances is strongly encouraged.

(8)

Exterior stairs. Simple, clean, bold projections of stairways are encouraged to complement the architectural massing and form of the structure. Thin-looking, open metal, prefabricated stairs are discouraged. Stairs should be enclosed

(9)

Mechanical and utility equipment. All mechanical equipment, either mounted on the roof, or ground, should be screened from view. Utility meters and equipment should be placed in locations that are not visible from the street. Screening devices shall be compatible with the architecture and color of the adjacent structures.

(10)

Compatible roof shapes. Rooflines of buildings should be compatible with surrounding building forms. The objective in determining roof shape is to establish a visual order to building clusters. However, varying roof heights and shapes may be appropriate on individual buildings and structures.

(11)

Roofing materials. Roofing materials shall consist of tile or simulated cement tile with a fire rating of Class B or higher.

(12)

Support facilities. Support structures (e.g., laundry facilities, recreation buildings, and sales/lease offices) should be consistent with the architectural design of the overall complex.

(13)

Solid waste bins. Trash bins should be fully enclosed with a masonry enclosure, either simulated wood or decorative metal gates and a trellis roof. The enclosure shall be finished with colors and materials that are consistent with the rest of the structures. Enclosures should be screened with landscaping on their most visible sides.

(14)

Utility and mechanical equipment.

a.

All mechanical equipment (e.g., compressors, air conditioners, heating and ventilating equipment, chillers, stand pipes, solar collectors, etc.) shall be concealed from view. Screening devices should be compatible with the architecture and color of the adjacent buildings.

b.

Mechanical equipment should not be located on the roof of a structure unless the equipment can be screened by building elements that are designed for that purpose and that are an integral part of the building design.

c.

Utility equipment (e.g., electric and gas meters, electrical panels, and junction boxes) should be located in utility rooms within the structure or utility cabinets with exterior access.

(15)

Service areas. Service areas, including maintenance buildings, shall be functional, appropriately screened and isolated from living areas and public right-of-way.

(16)

Elevator. For structures two stories or more in height, a minimum of one elevator shall be provided. Additional elevators may be required based on the design of structures or number of units in structure. The elevator shall be centrally located and in close proximity to entries. At least one of the elevators should have the dimensions and capacity of a service elevator.

(17)

Minimum dwelling amenities. At a minimum, each unit shall be provided with the following amenities:

a.

Central heating and air conditioning.

b.

Built-in dishwashers.

c.

Fully enclosed, securable storage closet not less than 100 CF in volume, located preferably adjacent to unit balcony or patio.

d.

Clothes washer and dryer electrical and gas hookups for standard washer and dryer appliances, and a bachelor/studio unit may provide facilities for stackable washer/dryer appliances.

e.

Call system with capability of 24-hour monitoring.

(18)

Driveway approaches. Driveway approaches serving senior citizen housing developments shall be delineated with enhanced paving treatment, such as interlocking pavers, textured and color, pigmented concrete, or stamped concrete.

(19)

Parking and circulation.

a.

Project entries. Project entries should provide the resident and visitor with an overview to the project through either an easy visual assessment (in smaller projects) or by providing signage or placards illustrate the circulation, parking, building, and amenity layout of the project. Special attention should be given to hardscape and landscape treatments to enhance the overall aesthetic image of the project.

b.

The principal vehicular access should be through an entry drive rather than a parking aisle. Colored, textured paving treatment at entry drives together with lush landscaping is strongly encouraged.

c.

If parking is not attached to the residential structures, covered carports and dispersed parking courts are the desired alternative.

1.

A parking court should not consist of more than two double-loaded parking aisles (bays) adjacent to each other.

2.

Carports should provide no more than five parking spaces within each structure. The structures should be constructed of materials consistent with those used in building construction, including, but not limited to, roofing materials, facade material, colors, and accents. Metal tubular construction is discouraged unless wrapped with a material consistent with the building design, such as stucco.

3.

The length of a parking court should not exceed 14 stalls. Parking courts should be separated from each other by dwelling units or by a landscaped buffer not less than five feet wide.

4.

Parking areas should be visible from the residential units which use them to the greatest degree possible.

5.

Parking courts shall be located within 150 from the dwelling unit (front or rear door) for which the parking space is provided.

d.

If the use of parking courts is not feasible and parking is provided around the perimeter of the buildings, then a minimum 15-foot landscaped buffer is required between the parking stalls and the building, excluding covered entryways which may extend outward from the building toward walkways leading from the parking area. The maximum number of consecutive parking spaces shall be ten, after which a landscape finger equal in size to a regular parking stall shall be provided.

e.

All design standards set forth in chapter 19.69 shall apply, except as may be specified herein.

(20)

Pedestrian access.

a.

Drop-off points should be provided at major building entries and plaza areas for all projects with more than 50,000 square feet of building floor area.

b.

Parking areas should be designed so that pedestrians walk parallel to moving cars in parking aisles. The project should be designed to minimize the need for the pedestrian to cross parking aisles and landscape islands to reach building entries.

c.

Stamped or painted concrete walkways should be provided in areas where it is necessary for pedestrians to cross drive or parking aisles.

d.

All projects should provide a clear connection between the on-site pedestrian circulation system and the off-site public sidewalk.

1.

Parking lots with over 200 stalls should provide a well-defined pedestrian walkway from the public sidewalk to the main on-site pedestrian circulation system. The walkway may be painted; however on large projects, a raised sidewalk may be required.

2.

When a pedestrian circulation route crosses a vehicle circulation aisle adjacent to a building entrance, the pedestrian crossing should be emphasized by extending the sidewalk to the back of the parking spaces (if they exist) and by painting a crosswalk through the traffic aisle.

(21)

Landscaping. Landscaping should serve to frame, soften and embellish the quality of the environment; buffer units from noise or undesirable views; visually reduce or break up building mass, break up large expanses of parking and hardscape and provide shading and cooling of adjacent units.

a.

All areas not covered by structures, drive aisles, parking or hardscape should be appropriately landscaped.

b.

Landscaped areas with a minimum 15-foot width shall be provided along public street frontage. Said planter shall consist of turf and also include the following:

1.

36-inch high berms.

2.

Mature trees (36-inch box or larger) planted 20 foot on center.

3.

Accent landscaping at driveway entries including large, developed trees.

4.

Street corners shall include accent landscaping using perennials and a focal point such as a waterfall or other entry monument.

(22)

Recreational facilities. Recreational amenities shall be appropriately distributed throughout the facility. Such facilities shall consist of open or enclosed areas for residents of the facility to congregate, for recreation and leisure. The following standards shall be utilized for recreational facilities:

a.

The design and orientation of these areas should take advantage of available sunlight and should be sheltered from the noise and traffic of adjacent street or other incompatible uses.

b.

Each recreational facility shall have a focal point. The focal point may consist of, but need not be limited to, water fountains, landscape planters, monuments, waterways, ponds, artwork, trellises or gazebos. The focal point of all recreational facilities shall complement one another by maintaining a common theme, consistent furnishing and signage.

c.

Recreational facilities shall be categorized as either "major recreational facilities" or "minor recreational facilities." Major and minor recreational facilities shall be designed to complement one another and be physically linked to one another by pedestrian walkways and directional signage. Major and minor recreational facilities shall be provided throughout senior citizen projects.

d.

Private open space. Each dwelling unit within a multiple unit residential development shall be provided a private open space area, free and clear of any attached or detached accessory structures, as follows:

1.

Ground level units shall be provided 100 square feet of private yard with a minimum interior dimension of ten feet.

2.

Upper level units shall be provided a 70-square-foot balcony, with a minimum dimension on at least one side of eight feet.

e.

Lighting. Lighting should provide illumination for the security and safety of residents in parking areas, recreational facilities, building entries, and pathways. The following standards shall be utilized.

1.

The design of light fixtures and their structural supports should be architecturally compatible with the main structures on the site. Light fixtures should be architecturally integrated into the design of a structure.

2.

The location of light fixtures should correspond to anticipated use. Lighting of pedestrian ways should illuminate changes in grade, path intersections, staging areas and any other uses along the path that, if left unlighted, would create an unsafe condition.

3.

All lighting fixtures must be shielded to prevent off-site glare.

4.

Night lighting of buildings is encouraged, but should be accomplished in a selective manner, avoiding overall building illumination that produces an undesirable look. Night lighting of buildings may be used to highlight special building features, emphasize repeated or decorative features, and use the juxtaposition of light and shadow to articulate the building facade.

f.

Public transportation amenities.

g.

On site. Sheltered bus stop with canopy provided with architecture consistent with the project shall be provided if required in coordination with local transit agencies.

h.

Off site. In cases when a public bus stop is located within the frontage of a proposed property, a bus stop enclosure or cover shall be provided with architecture consistent with project.

(23)

Security considerations.

a.

Provide clear, unobstructed sightlines from entries to the street or parking lot.

b.

Provide clear sightlines to outdoor open areas from doorways and windows.

c.

Light exterior spaces and internal common spaces with energy-efficient, vandal-proof lamps and fixtures.

d.

Create privacy for the ground-level units by using landscaping or fencing to buffer them from the street or parking.

e.

Pedestrian pathways to the entry, the parking, and the trash deposit area should be well-defined, well-lighted, and free from dense shrubs.

f.

Eliminate hidden recesses in hallways, entryways, and stairways. Ensure that there are no entrapment areas between buildings.

g.

Design common spaces to encourage a sense of belonging and that relate to a discrete number of units so that these spaces encourage a sense of ownership.

h.

Provide peepholes, strike plates, and deadbolts in unit doors.

(h)

Maintenance.

(1)

Continued good appearance depends on the extent and quality of maintenance. Materials and finishes shall be selected for their durability and wear, as well as for their beauty. Proper measures shall be taken for protection against weather, neglect, damage, and abuse.

(2)

Provision for washing and cleaning buildings and structures, and control of dirt and refuse, shall be included in the design. Configurations that tend to catch and accumulate leaves, dirt, and trash shall be avoided.
