SEC. 102. DEFINITIONS. For the purpose of this Article, the following definitions shall apply: (a) Nuisance. The discharge of sewage onto the surface of any public street, alley or place including sidewalks is a nuisance. (b) Hazard. Any cracking, sinking or undermining of the surface of any public street, alley or place including sidewalks caused by any absence, obstruction, failure or defect of any side sewer, private sewer, utility drain or private drainage system constitutes a threat to public safety and is a hazard. (c) Utility Drain. Any drain connected to a public sewer under the provisions of this Article and which serves a facility or structure installed or constructed under the provisions of Part II, Chapter X, Article 8 of the San Francisco Municipal Code (Public Works Code) is a utility drain. (d) Side Sewer (also known as lateral sewer). A side sewer is that portion of a sewer from the point of connection to a public sewer to a point of demarcation which shall be the front face of a curb or a curbline of record in a public street, alley or place, or the boundary line of record in an easement for public sewers, except that the point of demarcation shall be the first intersection of a private sewer which serves more than one building, lot or premises. In the absence of a curb or line of record, the Director shall establish a point of demarcation based on like public streets, alleys or places, or easements for public sewers. (e) Private Sewer. A private sewer is distinguished from a side sewer as being any other private sewer or drain installed in any public

street, alley or place including sidewalks, or easements for public sewers. (f) Reconstruction. Reconstruction shall include any side sewer work which requires alteration of the grade or alignment of an existing side sewer due to relocation of an existing private sewer or the installation of a new private sewer. (g) Roadway. A roadway is that portion of a public street, alley or place which is open for public vehicular traffic as distinguished from a sidewalk, sidewalk area, walkway, path, trail or private driveway. In an improved public street, alley or place, the roadway is from side curb to side curb. In an unimproved public street, alley or place the roadway shall be from curbline to curbline or such other lines of demarcation as the Director may establish. (h) Director. The Director of Public Works of the City and County of San Francisco. (Added by Ord. 114-77, App. 3/31/77) SEC. 103. OWNERSHIP AND RESPONSIBILITY FOR MAINTENANCE. All side sewers, private sewers, or utility drains are the property and maintenance responsibility of the owner or owners of property, facilities or structures tributary thereto. Repairs shall be at sole expense of such owner or owners except as provided in Section 103.1. (Added by Ord. 114-77, App. 3/31/77)

SEC. 103.1. SIDE SEWER REPAIR.

When the Department of Public Works determines that a repair must be made to a side sewer located in a public roadway or property, or connected to a sewer main located in an easement on private property, the repair shall be made by the Department of Public Works. In the case of a side sewer in a public roadway the Department of Public Works shall be responsible only for that section extending from the side curb or curb line to the sewer main connection. In the case of a side sewer connected to a sewer main on City property or in a City easement on private property, the section of the side sewer subject to such repair shall extend from the nearest property line of the benefited property to the connection with the sewer main. In the event the condition of a side sewer cannot be determined due to the lack of an appropriate vent or vented trap the Department of Public Works shall require the owner or owners to install such a vent or vented trap before making any repair under this Section. The Department of Public Works shall include a provision in the annual budget to cover the estimated costs of making repairs to side sewers as set forth herein in lieu of all fees or deposits as required by Sections 108 and 109 of this Article. This Section shall not be applicable to private sewers and utility drains as defined in Section 102 and referred to in Section 103 hereof. (Amended by Ord. 439-82, App. 9/3/82) SEC. 104. DIRECTOR TO ABATE NUISANCE OR HAZARD. Notwithstanding any other provisions of the San Francisco Municipal Code it shall be the duty of the Director to cause the abatement of a nuisance or hazard as provided in this Section. (a) When the source of a nuisance or hazard is in or on private property the Director shall direct the Superintendent of the Bureau of Building Inspection to abate the source of such nuisance or hazard in accordance with the provisions of Part II, Chapter VII of the San Francisco Municipal Code (Plumbing Code). The Director shall also notify the Director of Public Health of any such nuisance. The Director shall also abate any such hazard by work in or on public property in accordance with the provisions of Section 104(b) for other sources. (b) When the source of a nuisance or hazard is any side sewer, private sewer or utility drain the Director shall give written notice to abate. Notice shall be served by mailing said notice to the owner or owners of record of property tributary to a side sewer or private sewer or to the business office in the City and County of San Francisco of the owner of a utility drain. In the case of a side sewer or private sewer public notice shall be provided by posting of copies of said notice in the vicinity of said nuisance or hazard. The notice shall describe said nuisance or hazard, shall direct the owner or owners to abate the nuisance or hazard within 10 days of the mailing of notice and shall advise that the Director will abate the nuisance or hazard if the owner or owners fail to do so. The Director will abate the nuisance or hazard on failure of the owner or owners to do so within the 10 days. (Added by Ord. 114-77, App. 3/31/77)

SEC. 112. EXPENSE EXCEEDING ESTIMATE CONSTITUTES LIEN. If the expense of such construction, reconstruction or repair has been more than the aforesaid estimate given by the Department of Public Works, the person shall be indebted to the City and County of San Francisco for such balance; and the same shall constitute a lien upon the property of such person.
