Where any earth material for a project site is transported to or from the project site as part of the grading work, all of the following requirements shall apply.
(A) Either water or dust preventative spray material (or both) shall be consistently applied for prevention of dust resulting from the loading or transportation of earth to or from the project site on public roadways. The permittee shall be responsible for maintaining public rights-of-way, used for transporting materials, in a condition free of dust, earth or debris attributed to the grading work.
(B) Loading and transporting of earth materials to or from the site must be accomplished within the times set forth in § 7.90.130 (Time of Grading Work).
(C) Access roads to the site shall be only at points designated on the approved plans.
(D) At a minimum, the first 50 feet of access road adjacent to the intersection with the public roadway shall have a grade not to exceed 5%. There must be a 300-foot clear, unobstructed sight distance to the intersection from both the public roadway and the access road. If the 5% grade or 300-foot sight distance requirements cannot be obtained due to site constraints, then flagmen shall be posted at the access road and shall remain for the entire duration of material transportation operations. Any other design option to address sight distance issues shall require the approval of the City Engineer/Public Works Director.
(E) A stop sign conforming to the requirements of the California Vehicle Code shall be posted at the exit of the access road to the public roadway.
(F) Advanced warning signs along with traffic control and safety devices shall be reviewed and approved by the City Engineer/Public Works Director and shall be posted on the public roadway in the vicinity of the access intersection as required by the current California Manual on Uniform Traffic Control Devices (MUTCD). The size, shape, color, number, spacing, and other details of all such signs and devices shall conform to the standards contained therein and in the current State of California Department of Transportation (Caltrans) "Traffic Manual." The advanced warning signs and other devices shall be covered or removed when the access intersection is not in use.
(G) Site operators must install BMPs at the vehicle access points to prevent dirt and debris track-out onto public right of way. BMPs include, but are not limited to, stabilized construction entrances, tire washes, and rumble plates/shaker racks.
(H) A soil engineering report or geotechnical report shall be provided to the City Engineer/Public Works Director for all imported earth materials to be used as part of the grading operations. The report is subject to requirements of § 7.90.070 (Geotechnical Reports). The Geotechnical Engineer, Soils Engineer, or Engineering Geologist must certify the approximate source of the imported material, including the previous land uses from where the material was obtained.
(I) The City Engineer/Public Works Director may require the submittal of a Phase I and/or Phase II Environmental Assessment for any imported earth material.
(J) Imported earth material may not contain levels of contaminants exceeding the California Office of Environmental Health Hazard Assessment's Toxicology Criteria in California Code of Regulations, Title 22, Division 4.5, Chapter 51, Article 2, § 69021, Appendix I.
