(A) Maximum slope. Cuts must not be steeper in slope than two horizontal units to one vertical unit. The City Engineer or Building Official may allow a slope greater than 2:1 for special circumstances or site conditions. Before the City Engineer or Building Official may allow a greater slope, the owner must furnish a geotechnical engineering or an engineering geology report, or both, as requested by the City Engineer or Building Official, stating that the site has been investigated and giving an opinion that a cut at a steeper slope will be stable and not create a hazard to public or private property. Substantiating calculations and supporting data may be required where the City Engineer or Building Official determines that such information is necessary to verify the stability and safety of the proposed slope.
(B) Slope surface protection. All slopes must be stabilized against surface erosion. Stabilization may be accomplished through the application of erosion control blankets, soil stabilizers or other means as approved or directed by the City Engineer or Building Official.
(C) Drainage. Drainage, including drainage terraces and overflow protection, must be provided as required by Chapter 16.99 of this Title 16.
