Division 4 — (Reserved)

Division 5. Site Requirements

• [1] Applicable to OS Zone only.

In the OS Zone, any existing lawfully established lot (including a leased area of land during the term of the lease) is deemed to have the required lot area and lot width. No such lot shall be further reduced in area or width except:

• A. An acquisition of a portion of a lot may be made for public purposes; or

• B. When determined, in connection with the approval of a parcel map or tract map, that the division of land will not detract from the open space character of the area; or

• C. When a division of land is approved in connection with a Conditional Use permit; or

• D. When all of the lot within the OS Zone is dedicated for open space use.

In the OS Zone, no lot shall be created, and no new or additional use shall be developed on an existing lawfully established lot (including a leased area of land during the term of the lease) unless there is vehicular access from a public street or alley, and such access has a width of at least twenty (20) feet. The required vehicular access shall be either directly from a public street or alley or by means of a right-of-way or easement. (Ord. 79-460 § 4)

Division 6. Site Development Standards

[1] Applicable to OS Zone only.

In the OS Zone, all buildings and structures shall be incidental or subordinate to a primarily outdoor activity or open space use unless otherwise approved by a Conditional Use Permit.

In the OS Zone, there is no restriction on the height of buildings and structures except as may be required by a Conditional Use Permit.

In the OS Zone, the ground area included within the exterior walls and/or supporting columns of all roofed structures shall not exceed five (5) percent of the net lot area unless otherwise approved by a Conditional Use Permit or with the approval of a use by the Director or the Council as authorized under CMC § 9151.1 .

This Section is applicable only where portions of a lot are within areas planned to be part of future streets, alleys or public rights-of-way, as determined by the Director.

In cases to which this Section is applicable, unless otherwise approved by the Commission, the portion of any lot within such future right-of-way areas shall not be occupied by structures other than those encroachments allowed in future right-of-way areas pursuant to CMC § 9156.29 . All other required setbacks, yards and open spaces shall be provided in addition to the future right-of-way areas, and the future right-of-way lines shall be considered to be lot lines for purposes of measuring such other setbacks, yards and open spaces.

In the OS Zone, each lot shall have a yard with a depth of twenty-five (25) feet from each abutting street unless otherwise approved by the Director for the purpose of maintaining a larger contiguous open space on the interior portion of the lot.

In the OS Zone, where the side or rear of a lot abuts property in another zone, there shall be a yard on the subject property which conforms to the interior side and rear yard requirements, respectively, of such abutting zone.

Every part of a required yard or open space shall be open and unobstructed from finished grade to the sky except for those encroachments permitted pursuant to CMC § 9156.5 .

If not otherwise specified pursuant to this Division or in connection with a Conditional Use Permit, a use shall be required to meet the site development standards applicable to the use (or most similar use) within the most restrictive zone which permits such use, either automatically (X) or with limitations (L). (Interpretation of this provision is to be in accordance with CMC § 9172.24 .) (Ord. 93-1013 § 4)

In the OS Zone, no sign face shall have an area greater than fifty (50) square feet and the total sign area on a lot shall not be greater than two hundred (200) square feet, except as otherwise approved in connection with a Conditional Use Permit or in connection with an approval of a use by the Council as authorized in CMC § 9151.1 .

All new utility lines, other than major transmission lines, shall be placed underground. This requirement may be waived by the Commission where topography, soil, undue financial hardship or other conditions make such underground installation unreasonable or impractical. Undergrounding shall be in accordance with the applicable rules and regulations of the utility, as currently on file with the California Public Utilities Commission.

All aboveground equipment (other than pole lines when permitted), such as transformers and pedestal terminals, which are visible from an adjacent public street or walkway, shall be within a solid enclosure or otherwise screened from public view. Such enclosure/screening shall be in accordance with the utility's service requirement. (Amended by Int. 3-79)

Within any D (Design Overlay) designated area all development subsequent to the date of such designation shall be in conformance with development plans which have been approved pursuant to the Site Plan and Design Review procedure as provided in CMC § 9172.23 . No permit shall be issued for grading or construction involving significant exterior changes, as determined by the Director, which is not in conformance with such approved development plans.

Division 7. Environmental Effects

All lighting of buildings, landscaping, parking lots, recreation areas and similar facilities shall be directed away from all adjoining and nearby residential property. Such lighting shall be arranged and controlled so as not to create a nuisance or hazard to traffic or to the living environment. This Section is also applicable to arc lights, searchlights and similar devices.
