Chapter 5. Preliminary Plans And Surveys of California Streets And Highways Code >> Division 9. >> Part 2. >> Chapter 5.

Before the construction of any project, and before the calling of any election for the issuance of bonds, the commission shall employ one or more engineers, or contract for engineering services with any city within the district or with the county, who shall make all necessary surveys, and prepare maps showing the location, cross-section and profile of the proposed project. The engineer shall also prepare specifications for the construction of the project and estimates of the cost of construction and of acquiring rights of way. These surveys, maps, specifications and estimates shall, upon approval by the commission, be promptly adopted by order entered upon the minutes and filed with its secretary, and when so adopted shall constitute the plan of the district for the proposed project.

Notwithstanding the provisions of Section 8117, upon the completion of the surveys referred to in Section 8160 and upon recommendation of the engineer or engineers, in which recommendation shall be included the estimate of cost of each proposed improvement, the commission by resolution duly adopted and recorded in its minutes may approve any changes in the location or locations of the projects described by the board of supervisors in its resolution of intention to form the district, as to the commission may appear reasonable and proper under the circumstances. The said resolution shall set forth the reasons for such changes or additions and the cost of each project as recommended in the engineer's report.
