Work shall not proceed until the Engineer has approved the project-specific erosion and sedimentation control plan. Types of erosion and sedimentation control measures that may be required include but are not limited to: preservation of existing vegetation; temporary seeding and planting; permanent seeding and mulching; mulching; soil stabilizers; geotextiles, mats/plastic covers, and erosion control blankets; temporary stream crossings; stabilized construction entrances; entrance/outlet tire washes; check dams; slope roughening/terracing/rounding; silt fences; straw bale barriers; sandbag barriers; straw wattles; brush or rock filters; storm drain inlet protection; sediment basins; and sediment traps. At a minimum, the Contractor shall install filter materials (such as sandbags, filter fabric, etc.) at the storm drain inlets located in and downstream of the project site between October 15 through April 15 and/or, when rain is forecast, within twenty-four (24) hours. The Contractor shall install filter materials or seal all surface inlet openings during the dry season if there is potential for sediment or excavated material to be discharged to the storm drain system during the construction operation (e.g., sediments and debris tracked by construction vehicles, windblown, or transported by other runoff). The storm drain inlets shall be sealed in such a manner that they can be opened in an emergency and unblocked at the end of each working day so that no property is damaged as a result of accidents or other overflows. Contractors shall always prevent erosion of materials by wind. Sedimentation and erosion control/filter materials shall be placed in a manner that will retain any debris or sediment from flowing into the storm drain system and/or off site. Such materials or control devices shall also be maintained and/or replaced as necessary to ensure effective sediment control and to prevent flooding. The Contractor shall be responsible for monitoring and update erosion control plans to accommodate phased construction and as necessary, modify plans to fit existing conditions. - 37 - - 38 - Changes in plans will require City review and approval. 5-02 Not Included 5-03 Not Included 5-04 Measurement Erosion and sedimentation control shall not be a measured item unless specified in the Special Provisions. 5-05 Payment Full compensation for erosion and sedimentation control shall be considered as included in the contract unit price paid for the various items of work and no additional compensation will, therefore, be allowed.
