Mark Clearing Limits: Prior to clearing or disturbing the limits must be marked. This element is <br />part of most normal construction plans as one of the first steps. <br />2. Establish Construction Access: All erosion control plans shall instal a stabilized construction <br />entrance (or other method of preventing sediment transport onto the roads). If o standard <br />gravel construction entrance is proposed, use geo-textile fabric under the rock. Note: a <br />wheel wash is required for plans that propose winter grading. <br />3. Detain Flows: Based on a downstream analysis it may be necessary to detain runoff from a <br />site under construction. It may be necessary to construct and use a detention pond to <br />control flows during construction. <br />O <br />W_ <br />Ci <br />O <br />J <br />0 <br />Z <br />W <br />P_ <br />d <br />MJ <br />LLi <br />ZM <br />C a N <br />C <br />LO <br />Q N <br />09 <br />0M <br />N 'c <br />A <br />w <br />4. Instal Sediment Controls: If there is runoff from the construction site, sediment shall be <br />removed from the water. Note that the water quality standards must be met. <br />Q <br />5. Stabilize Soils: All exposed and non -worked sot shall be stabilized by use of BMP's. Note <br />= N <br />there are time periods of allowed exposure that depend on the season. Groundcover <br />both temporary and permanent need to be part of the construction plans. <br />y <br />6. Protect Slopes: Cut and fill slopes need to be protected from erosive flows and <br />`—" a <br />concentrated flows until permanent cover and drainage conveyance systems are in <br />place. <br />U <br />U (°J <br />U <br />7. Protect Drain Inlets: Al storm drain inlets require protection from sediment and sat laden <br />P O <br />o <br />CL <br />water. <br />° <br />0 <br />U <br />8. Stabilize Channels and Outlets: Temporary and permanent conveyance systems shall be <br />0- <br />< <br />fn <br />staba'¢ed to prevent erosion during and offer construction. Culvert outlets require <br />LU <br />protection. <br />� <br />F- <br />9. Control Pollutants: The plan shall show how all pollutants, including waste materials and <br />J 3 <br />demolition debris, will be handled. This includes maintenance of construction equipment, <br />= <br />} <br />fertilizers, application of chemicals, and water treatment systems. <br />_ c <br />10. Control De -Watering: The water from de -watering systems for trenches, vaults and <br />o <br />S <br />J <br />foundations shall be discharged into a controlled system. <br />9 <br />11. Maintain BMPs: The an shill <br />plan provide for inspection and maintenance of the planned and <br />1 <br />N <br />� <br />installed construction BMPs as well as their removal at the end of the project. <br />12. Manage the Project: The plan shall outline how the site shall be managed for erosion <br />a� <br />control and identify the management team. It needs to cover phasing, training, <br />U <br />pre -construction conference, coordination with unities and contractors, monitoring and <br />—' <br />reporting. It shall provide for notice of problems, revisions during construction and <br />U L <br />contingency planning. One of the most important elements in the management of the <br />U <br />project is planning for contingencies based on the risk of exposure during phases of the <br />CL m <br />development. It is essential that planning is ongoing throughout the life of the project. <br />13. Protect on -Site stormwater management BMPs for runoff from roofs and other <br />SHEET <br />C3 C4 <br />hard surfaces. On -site Stormwater Management BMPs shall be protected at all <br />or <br />times during the construction process. This may mean that stormwater <br />1x17 <br />management BMPs will be installed towards the end of the construction process <br />to avoid siltation and compaction. <br />0 <br />0 <br />s_ <br />
