CHAPTER IV. OF SEWERS AND DRAINAGE. SECTION 1. The Board shall devise a general system of drainage which shall embrace all matters relative to the thorough, systematic and effectual drainage of not only surface water and filth, but also of the soil on which said city is situated, to a sufficient depth to secure dryness in cellars and entire freedom from stagnant waters, and in such manner as best to promote the cleanliness and healthfulness of said city and county, and shall report to the Supervisors in reference thereto, and shall from time to time make to the Supervisors such recommendations upon the subject of sewerage and drainage as it may deem proper. SEC. 2. The Board shall prescribe the location, form and material to be used in the construction, reconstruction and repairing of all public sewers, manholes, sinks, drains, cesspools, and other appurtenances belonging to the drainage system, and of every private drain or sewer emptying into a public sewer, and shall determine the places and manner of such connection. SEC. 3. The Board shall have power to recommend rules and regulations and restrictions concerning the public and private sewers and drains in said city and county, and upon the recommendation of said Board the Supervisors are authorized to pass an ordinance establishing the same and prescribing the penalties for any violation thereof. SEC. 4. No person shall make connection with or open or penetrate into any public sewer or drain without first obtaining a permit in writing from the Board of Public Works, and complying with the rules and regulations of the Board in reference thereto.

SEC. 6. The Board may also recommend to the Supervisors the construction of such canals, sewers, ditches, drains, embankments, reservoirs, pumping works, machinery, and other works necessary for a proper and effectual drainage of said city and county, together with plans for connecting the same with sewers and private drains already constructed or thereafter to be constructed. SEC. 7. The Supervisors shall not authorize the construction of any sewer or drain, except upon the recommendation of said Board. SEC. 8. The Supervisors may, by ordinance, upon the recommendation of said Board, authorize the purchase of any personal property, or the acquisition by purchase or condemnation of any real estate which may be necessary for the construction of any sewer or the making of any improvement provided for in this Chapter. The title to all real estate purchased shall be taken in the name of the city and county. SEC. 9. The said Board may also, with the like approval of the Supervisors, agree with the owners of any real estate upon which it is deemed desirable to construct any sewer or other improvement relative to sewerage or drainage, upon the amount of damage that is to be paid to such owners for the purpose of such improvement and for the perpetual use of said real estate for such purpose. SEC. 10. Whenever, upon the recommendation of said Board, the Supervisors shall determine upon any improvement for purposes of sewerage and drainage which necessitates the acquisition or condemnation of private property, and the Board of Public Works are unable to agree with the owner or owners thereof upon the amount of compensation or damages to be paid therefor, or whenever such owner or owners are in any way disqualified or incapable of making any agreement in reference thereto, and in all cases in which said Board shall deem it most expedient, the said Board shall, upon the approval thereof of the Supervisors, expressed by ordinance, have the right to cause the said property to be condemned, and to institute proceedings for the condemnation of such property, or for the ascertainment of such damages in the manner, so far as the same is applicable, which is herein provided for the condemnation of real estate when necessary for the opening of any new street. CHAPTER V. OF THE NEW CITY HALL. SECTION 1. The Board of Public Works, whenever authorized by the Supervisors, evidenced by ordinance, and when the necessary money has been provided therefor, may proceed with the construction of the buildings and improvements on said premises; known as the New City Hall, according to the plans heretofore adopted for the construction of the same. SEC. 2. The Secretary of the Board shall keep the records of the proceedings of said Board, respecting the construction of the New City Hall, in the same books in which they have hitherto been kept; and the said records shall be kept distinct from the general records of said Board, and be open to the inspection of the public at any time during office hours. The said Secretary shall keep full and correct minutes of all the proceedings of said Board respecting the construction of said New City Hall, and shall keep an accurate account of the receipts and disbursements thereof, and shall keep an accurate account with each officer, clerk, contractor and employee for any work or material done or furnished for the construction of said New City Hall, SEC. 3.

Said advertisement shall contain a general description of the work to be done and the materials to be furnished, the time within which the same is to be done or furnished, the amount of the bond to be given as security therefor, and shall refer to plans and specifications for such other details as may be necessary to give a correct understanding regarding the work or materials, and shall also state the day, and the hour on said day, when said bids will be received and opened. The provisions contained in Chapter II of this Article, in reference to bids and proposals, and awarding and entering into contracts and giving bonds for the performance, of such contracts, are hereby made applicable to all contracts to be entered into for the completion of the New City Hall. SEC. 4. For the purpose of raising the money necessary to complete said building, the Supervisors may, at their discretion, in making the annual tax levy for city and county purposes, apportion to the New City Hall Fund an amount not to exceed ten cents on each one hundred dollars of value, as shown by the assessment roll of said city and county for the ensuing fiscal year.

All claims against the said fund shall be allowed by the Board in the same manner as other demands upon the City and County Treasury. SEC. 6. Said Board may allow the claims of the contractors, from time to time, as work progresses or materials are furnished, but until the contract is completed such demands thereon allowed shall not exceed seventy-five per cent of the value of the labor or material furnished, which said value shall be ascertained and determined by the certificate of the Architect and Superintendent, subject to the approval of said Board. SEC. 7. The said Board shall, on or before the first day of August in each year, transmit to the Supervisors a statement showing the moneys expended during the preceding fiscal year, the contracts upon which the same were expended, the amount due upon unfinished contracts, and a list of the contracts awarded and unfinished, and the amount of money that will be required for each of said contracts within the current fiscal year, and the estimated amount required to complete the said New City Hall, and such other matters as will show the progress made in the construction of the said New City Hall.
