§ 17.04.430 — Erosion control

17.04.430 - Erosion control.

A. Slopes. The faces of cut and fill slopes which accept overland or sheet flow or any cut or fill slope of erodible material over three feet in height shall be treated with an approved erosion control treatment immediately following completion of construction when rough grade has been attained between November 1st and May 31st, or before November 1st if rough grade is attained between May 31st and November 1st. An approved erosion control plan may include effective planting or other erosion control devices and may require maintenance in a manner satisfactory to city by means of contracts, deed restrictions, or other instruments approved by city. B. Other Devices. Check dams, sedimentation basins, cribbing, riprap or other devices or methods to control erosion and sediments shall be employed when necessary to provide safety and protect water quality. C. Exception. Where cut slopes are not subject to erosion due to the erosion-resistant character of the materials, protection specified under subsection A and B, above, may be omitted, as permitted by the director. D. Bonding. The director may require bonds in such forms and amounts as may be deemed necessary to assure that the work, if not completed in accordance with the approved plans and specifications, will be corrected to eliminate hazardous conditions or protect water quality.
