In subdivisions within reasonable distance of a sanitary sewage disposal system, the subdivider shall be required to install a complete sewerage system connected thereto.
In districts where no sanitary sewage disposal system exists and where the subdivision is not within a reasonable distance of same, other provisions for disposal of sewage shall be made in accordance with City health regulations and recommendations of any existing sanitary district or City. A statement from the City Health Officer certifying that sewage disposal plans are satisfactory, together with a set of sewage disposal plans, showing lines, grades and structures, shall be filed with the Planning Commission with the tentative map.
The subdivider shall provide an adequate water supply in accordance with plans approved by the Planning Commission.
The subdivider shall improve all streets, highways, public ways, alleys and easements which are a part of the subdivision. The required improvements shall be such as may be necessary for the general use of the residents of the subdivision and local neighborhood traffic and drainage needs; and shall include the grading, paving and other improvements of streets, highways and public ways as may be necessary to the use of streets and highways or the drainage thereof and to the public safety.
The subdivider shall provide such structures and/or storm sewers necessary for adequate drainage of the subdivision.
The City Council or their authorized representative shall have the right to enter upon the site of the improvements for the purpose of inspecting the same and shall be furnished with samples of materials as they may require for the making of tests to determine the acceptability of such materials. The subdivider shall pay to the City the actual cost for the inspection of the work at the prevailing wage rates and the cost of checking of the materials for the improvements during the entire period of construction. When the final map is presented to the City Council, the subdivider shall give evidence that he had deposited with the City a sum in the amount estimated by the Council as being sufficient to cover the costs of such inspection and tests, and other engineering costs. If the amount so deposited exceeds the actual cost to the City, the subdivider shall be reimbursed for the balance remaining. If the actual cost exceeds the deposited amount, the City shall stop all construction until the subdivider shall present a receipt for a deposit with the City of an additional sum as estimated by the City Engineer. All moneys shall be paid to the City, to be held in escrow for inspections, tests and checking of the materials for improvements, and other engineering costs.
When spreading oil, care shall be taken that no oil is left on any curbs, sidewalks or any other improvements other than the actual roadbed upon which oil is to be spread. No concrete shall be mixed either by hand or machine within the limits of the street lines unless precaution is taken so that none of the concrete will stain or discolor any of the roadway surfacing and other improvements.
All subdivision improvements must be constructed in accordance with plans, profiles, cross sections and specifications as approved by the City Planning Commission.
The minimum requirements for street improvement to be accepted by the City for maintenance will consist of a five-inch rock base pavement with a one-inch asphaltic armor coat surface. Grades exceeding 15 percent will require a five-inch rock base with a two-inch plant mix surface.
A concrete curb and gutter will be required on at least one side of all roads of a capacity sufficient to take care of watershed which lies above it.
Sidewalks, curbs, and gutters shall be constructed of Class “A” concrete (five sacks of portland cement per cubic yard). Standard curbs and gutters shall be used on returns at street intersections.
Roadway curves shall have a minimum center line radius of 60 feet.
Corrugated metal pipe shall have paved bottom to prevent scour. A complete drainage plan shall be furnished before the City Council is asked for acceptance of the subdivision.
The State of California, Department of Public Works, Division of Highways Standard Specifications of January 1949 shall be used as specifications for each class of work performed and no specification of less requirements will be acceptable to the City Council.
Nothing in these specifications shall be construed to prohibit the subdivider from constructing, or the City specifying, a higher type of improvement than herein specified where anticipated traffic would require.
All improvements to be constructed in accordance with City standards. [Ord. 430 § 3, 1950.]

If the required improvement work is not completed satisfactorily before the final or parcel map is filed, the owner or owners of the subdivision shall concurrently with the approval of such map enter into an agreement with the City Council agreeing to have the work completed within the time specified in the agreement. The agreement may provide for the improvements to be installed in units, for extensions of time under the specified conditions or for the termination of the agreement upon a reversion of the subdivision or a part thereof to acreage. Such agreement shall be secured by cash or corporate surety bond of sufficient amount to cover all improvements not completed and to be approved by the City Council. [Ord. 984 § 2, 1981; Ord. 430 § 4, 1950.]
