CHAPTER 14

62 - PUD PLANNED UNIT DEVELOPMENTS

Sections:


14.62.010 - Planned unit developments (PUD).

The regulations, general provisions, and exceptions set forth in this chapter and in Chapter 14.66 shall apply in all planned unit developments.

(Prior code § 10-2.2401)

14.62.020 - Purpose (PUD).

In certain instances the objectives of the zoning provisions may be achieved by the development of planned units which do not conform in all respects with the land use pattern designated on the zoning map or the district regulations prescribed by this chapter. A planned unit development may include a combination of different dwelling types and/or a variety of land uses which complement each other and harmonize with existing and proposed land uses in the vicinity. In order to provide locations for well-planned developments which conform with the objectives of the zoning provisions, although they deviate in certain respects from the zoning map and the district regulations, the council is empowered to grant use permits for planned unit developments provided the developments comply with the regulations set forth in this chapter.

(Prior code § 10-2.2402)

In any R1 Districts, a PUD/R1 Cluster may be granted by the commission and council in accordance with the requirements set forth in this section.

A.

Intent. The intent of a PUD/R1 Cluster is to provide for flexibility and variety in the location of dwelling units on a lot and diversity of lot sizes, to promote a more desirable living environment, to encourage developers to use a more creative approach in land development in order to conserve natural features, and to facilitate the provision of more desirable, aesthetic, and efficient use of open space on parcels where natural features would be destroyed under normal subdivision practices.

B.

Standards. The following standards shall govern the issuance of a PUD/R1 Cluster:

1.

Uses permitted. One-family dwellings.

2.

Density. The maximum number of permitted dwelling units shall be calculated by subtracting twenty (20) percent of the gross area of the parcel and dividing the remainder by the required lot area per dwelling unit in the appropriate R1 District (ten thousand (10,000) square feet in the R1-10 District, fifteen thousand (15,000) square feet in the R1-H District, twenty thousand (20,000) square feet in the R1-20 District, and forty-three thousand five hundred sixty (43,560) square feet in the R1-40 District).

3.

Coverage. All buildings and structures shall not cover a total of more than thirty (30) percent of the net area. Roadways and streets shall not be deemed to be structures.

4.

Minimum lot area, yard requirements, and other setbacks. Minimum lot area, yard requirements, and other setbacks shall be as proposed by the applicant and approved by the commission and council and shall be consistent with the intent of this chapter.

5.

Public lands and open space. The applicant may be required to reserve sites for schools or such other public uses as may be determined by the commission and council to be necessary and to reserve adequate open space for the recreational and leisure use of the population that will occupy the cluster development which will enhance the present or potential value of abutting or surrounding development. Insofar as possible, the commission and council shall assure that natural features of the land are preserved and landscaping is provided. Provisions for the maintenance of open space shall be reviewed and approved by the commission and council. Documents dedicating development rights and provisions for the maintenance of open space and all other documents as submitted to the State Real Estate Commission shall be reviewed and approved by the city attorney.

6.

Parking. Two covered parking spaces shall be required for each dwelling unit.

7.

Circulation. There shall be adequate vehicular and pedestrian circulation facilities which shall be designed and arranged for safe and convenient use in accordance with accepted site planning standards approved by the commission and council. Street widths shall be a minimum of twenty (20) feet. Pedestrian walks, malls, and landscaped spaces shall be located and arranged to discourage the pedestrian use of parking and other vehicular areas and to protect pedestrian walks and areas from unnecessary exposure to the hazards of vehicular movement.

8.

Light and air orientation and design. Walls containing main window exposures shall be so oriented as to ensure adequate light and air, taking into consideration sun and other climatic features, such as prevailing breezes, shall be so arranged as to avoid undue exposure to the effects of traffic, loading, and parking facilities, and shall be so designed and oriented as to preserve visual and auditory privacy between buildings.

9.

Height. The maximum height shall be two stories or thirty (30) feet, whichever is the lesser. The maximum height of accessory structures shall be one story or twelve (12) feet.

10.

Landscaping. The commission and council may require landscaping in addition to such natural features as exist if, in their opinion, such additional landscaping is needed for the protection and comfort of those who are adjacent to or those who will occupy the proposed development. Such additional landscaping shall be approved by the building and planning department.

11.

Minimum site area. The minimum site area for a PUD/R1 Cluster shall be one acre in the R1-10 District; two acres in the R1-H and R1-20 Districts; and five acres in the R1-40 District.

12.

Procedure. Any person desiring a PUD/R1 Cluster shall file with the commission an application, the form of which shall be prescribed by the commission.

13.

Development plans. The application shall be accompanied by a development plan which shall meet all the requirements as to form and content of a tentative map of five or more lots required by the subdivision provisions set forth in Title 13 of this code. The development plan may be processed concurrently with a tentative map. The development plan shall be reviewed by the architecture and site control committee and shall include:

Whether the proposed conditional use will comply with the regulations prescribed for the district in which the site is located and the general provisions of this chapter; or

ii.

Disapprove the petition and abandon the proceedings thereon. Denial by the commission shall be final; however, the applicant may appeal to the council. Such appeal shall be filed in writing with the city clerk within five days after the commission action.

17.

Council action. At the time and place set for the council hearing, notice of such hearing to be as provided in Section 14.80.030, the council shall review the tentative plan for the planned unit development. The council shall consider the report of the commission and may accept, modify, or reject any recommendation of the commission. If the tentative plan for the cluster permit is approved by the council, it shall continue the hearing to a date certain and refer the matter to the commission for a report with recommendations for final detailed architecture and site approval and recommendations regarding the commencement and completion dates.

18.

Granting cluster permits. A PUD/R1 Cluster permit may be granted by the commission and council when development under such a permit would be consistent with the intent and requirements of this section.

The cluster permit shall be deemed automatically revoked if the use for which the permit was granted has either not been established within one year after the granting of the permit, or has ceased, or has been suspended for a period of twelve (12) consecutive months.

(Prior code § 10-2.2420)

14.62.210 - Senior citizen housing regulations (PUD/SC).

A.

Purpose. The purpose of the PUD/SC District is to provide opportunity for the development of housing for persons sixty-two (62) years of age or older, or fifty-five (55) years of age or older if the senior housing project includes a minimum of thirty-five (35) units, under the auspices, ownership, and/or management of a responsible and competent organization. To assure the continued use of the project for this purpose, the developer shall be required to enter into an agreement with the city.

B.

Location. A PUD/SC project may be permitted only at locations designated in the Los Altos General Plan for senior citizen housing projects.

C.

Required conditions. The following conditions shall be required:

1.

Age restriction. At least one resident of each unit shall be sixty-two (62) years of age or older, or fifty-five (55) years of age or older if the senior housing project includes a minimum of thirty-five (35) units.

2.

Project amenities. In order to create a desirable living environment, the project shall provide a variety of common facilities consistent with the scale of development, such as a dining room, indoor and outdoor recreation areas, lounges, and meeting rooms. Medical care facilities are also permitted.

3.

Unit size. In order to provide the senior housing public with a choice of housing relative to family size and economic and social needs, the project shall provide a mix of unit sizes as approved by the planning commission and city council. Although a maximum unit size is not stipulated, it is not the intent of the PUD/SC zone to provide housing comparable in size with detached single-family homes.

4.

General screening standard. Every development shall provide sufficient screening to reasonably protect the privacy, safety, and environment of neighboring residential properties and shield them from adverse external effects of that development.

5.

Sites for screening of refuse collection. Every development will be required to provide suitable space for solid waste separation, collection, and storage, and shall provide sites for such that are located so as to facilitate collection and minimize any negative impact on persons occupying the development site, neighboring properties, or public rights-of-way.

6.

Lighting. Lighting within any lot that unnecessarily illuminates any other lot and/or substantially interferes with the use or enjoyment of such other lot is prohibited. Lighting unnecessarily illuminates another lot if: (i) it clearly exceeds the minimum illumination necessary to provide for security of property and the safety of persons using such roads, driveways, sidewalks, parking lots, and other common areas and facilities; or (ii) the illumination could reasonably be achieved in a manner that would not substantially interfere with the use or enjoyment of neighboring properties.

7.

Maintenance of common areas, landscaping, improvements, and facilities. Maintenance of all common areas, landscaping, improvements or facilities required by this section or any permit issued in accordance with its provisions shall be required except those areas, improvements, or facilities with respect to which an offer of dedication to the public has been accepted by the appropriate public authority.

8.

Noise. No person shall operate, or cause to be operated, any source of sound at any location within the city or allow the creation of any noise on property owned, leased, occupied, or otherwise controlled by such person, which causes the noise level, when measured on any other property, either incorporated or unincorporated, to exceed standards as set forth in Chapter 6.16 of this title.

In order to attenuate noise associated with a senior housing development, walls exceeding six feet in height may be required. Other conditions may be applied such as, but not limited to, muffling of exterior air-conditioning facilities.

D.

Development standards. The following standards shall apply in the PUD/SC District:

1.

Density. The maximum density shall be as designated in the Los Altos General Plan for the specific site.

2.

Setbacks, floor area ratio, and coverage. Setbacks, floor area ratio, and coverage shall be established by the planning commission and city council upon review of a project proposed by an applicant and shall be consistent with the objectives of the zoning plan stated in Article 1 of Chapter 14.02. It is intended that at the perimeter of the project, the minimum setback requirements of adjoining residential zoning districts, or similar setbacks, will be observed.

3.

Height. No structure shall exceed two stories or twenty-seven (27) feet in height, whichever is the lesser. The daylight plane principle used in connection with single-family residential developments shall be observed in order to assure that the height and bulk of structures will not create an adverse impact on surrounding properties.

4.

Parking. Sufficient parking facilities shall be provided on-site to meet the parking needs of the project, including parking for residents, employees, and visitors. The developer shall be required to retain the services of a traffic engineering consultant (to be selected by and contracted through the city) for the purpose of determining the parking needs of the proposal project and the traffic impacts. The consultant's research shall include studies of the parking needs of similarly operated senior housing facilities in the region, taking into account the number of units, the size of the units, services provided, size of staff, overlapping shifts, visitor parking needs, and the proximity of the project to shopping and public transportation. The planning commission and city council will use the study results to determine the number of parking spaces to be required for the project.

5.

Landscaping. Landscaping shall be provided for the protection and comfort of those persons living adjacent to and within the project as well as for the environmental protection of the community. The landscaping shall be designed to provide privacy and/or buffering for adjacent neighbors and passersby.

E.

Design control.

1.

No structure shall be built or altered, including exterior changes in color, materials, and signage, except upon approval of the city planner for minor changes and architectural and site approval to be obtained as prescribed in Chapter 14.78 of this title for major changes.

2.

When the location of a senior housing project is within the context of a residential neighborhood, such as Hawthorne Avenue and Eleanor Avenue, elements of design shall retain the low-profile residential appearance, and surface materials shall only be those which are in keeping with the traditional materials of the neighborhood.

3.

When the location is within the context of a larger region, such as San Antonio Road and Edith Avenue or San Antonio Road and Chester Circle, a mixture of scales may be appropriate with some elements scaled for appreciation from the street and moving automobiles and others for appreciation by pedestrians.

4.

The proportions of building elements, especially those at ground level, shall be kept close to human scale by using recesses, courtyards, entries, or outdoor spaces.

5.

The proportions of building elements at a multifamily residential/single-family residential interface shall be designed to avoid unreasonable interference with views and privacy of the adjoining neighbors.

6.

Rooftop mechanical equipment must be within the height limit and screened architecturally from public view.

F.

Procedures for development plan approval. The procedure for approval of a PUD/SC project shall be in accordance with the provisions outlined in Sections 14.62.130 through 14.62.150 of this chapter. The requirement for a two-phase review of preliminary plans and final plans may be waived at the discretion of the city planner.
