Summary
Huntington Beach's Grading Code requires every construction site to control erosion on cut and fill slopes, using desilting basins, check dams, or riprap during the rainy season. No site may grade more than 200 cubic yards between October 1 and April 30 without an approved erosion control system, and a civil engineer must oversee the devices all season.
A. The faces of cut and fill slopes and the project site shall be prepared and maintained to control against erosion in accordance with this Code. Where cut slopes are not subject to erosion due to erosion-resistant character of the materials, such protection may be omitted upon approval by the Director. B. Where necessary, temporary or permanent erosion control devices such as desilting basins, check dams, riprap, or other devices or methods as approved by the Director, shall be employed to control erosion and provide safety during the rain season, from October 1st to April 30th. C. No grading work in excess of 200 cubic yards will be allowed between October 1st and April 30th on any single grading site under permit unless an erosion control system has been approved or waived by the Director.
Full Breakdown
310, Erosion Control and Water Quality Requirement Systems, opens by requiring that 'the faces of cut and fill slopes and the project site shall be prepared and maintained to control against erosion in accordance with this Code,' though the Director can waive protection on slopes made of erosion-resistant material. Where protection is needed, subsection B requires 'temporary or permanent erosion control devices such as desilting basins, check dams, riprap, or other devices or methods as approved by the Director' during the rainy season, defined as October 1st through April 30th.
' Subsection D requires paved streets, sidewalks and other improvements near the site to stay free of loose soil, construction debris, and trash, using street sweeping rather than hosing to keep sediment out of storm flows. Subsection E puts the ongoing engineering on the property owner: a retained civil engineer must design the erosion control improvements, approve their installation each rainy season, and periodically review field conditions to modify the devices as needed, while subsection F makes the owner responsible for maintaining desilting facilities at every drainage outlet from the graded site.
Violations & Fines
Grading or building work that ignores these erosion controls can be shut down on the spot: Section 17.05.100 lets the Director 'order the work stopped by notice, in writing, served on any persons engaged in the doing or causing such work to be done,' and work must stay stopped until the Director authorizes resumption. Beyond the stop-work order, a violation is also prosecuted under Chapter 1.16 as a misdemeanor, up to six months in jail and a $1,000 fine, or an infraction starting at $100 for a first offense and climbing to $500 for repeat offenses within a year.
