EROSION CONTROL ELEMENT # 5 - Stabilize Soils Requirements Stabilize Soils From October 1 through April 30, no soils shall remain exposed and unworked for more than 2 days. From May 1 to September 30, no soils shall remain exposed and unworked for more than 7 days. This condition applies to all soils on site, whether at final grade or not. These time limits may be adjusted by the city if it can be shown that the average time between storm events justifies a different standard. (Requests to modify these timeframes must be made in writing and approved by the City of Everett before any deviation in these erosion control measures is permitted.) 2. Soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on the weather forecast. 3. Soil stockpiles must be stabilized from erosion, protected with sediment trapping measures and when possible, be located away from storm drain inlets, waterways and drainage channels. 4. Linear construction activities, including right-of-way and easement clearing, roadway development, pipelines, and trenching for utilities, shall be conducted to meet the soil stabilization requirements. Contractors shall install the bedding materials, roadbeds, structures, pipeline, or utilities and re -stabilize the disturbed soils so that: From October 1 through April 30 no soils shall remain exposed and unworked for more than 2 days and From May 1 to September 30, no soils shall remain exposed and unworked for more than 7 days. Soil stabilization measures should be appropriate for the time of year, site conditions, estimated duration of use, and potential water quality impacts that stabilization agents may have on downstream water or ground water. Applicable practices include, but are not limited to, temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics and matting, soil application of polyacrylimide (PAM), the early application of gravel base on areas to be paved, and dust control. The following Best Management Practices, (BMPs), the ones that the Contractor will implement on site, to meet the erosion control requirements listed above: 10
