1 <br />F_� <br />Appendix 11-A: Recommended Standard Notes for <br />Erosion Control Plans <br />The following standard notes are suggested for use in erosion control plans. Local jur- <br />isdictions may have other mandatory notes for construction plans that are applicable. <br />Plans should also identify with phone numbers the person or firm responsible for the pre- <br />paration of and maintenance of the erosion control plan. <br />Standard Notes <br />Approval of this erosion/sedimentation control (ESC) plan does not constitute an <br />approval of permanent road or drainage design (e.g. size and location of roads, pipes, <br />restrictors, channels, retention facilities, utilities). <br />The implementation of these ESC plans and the construction, maintenance, replace- <br />ment, and upgrading of these ESC facilities is the responsibility of the applic- <br />ant/contractor until all construction is completed and approved and <br />vegetation/landscaping is established. <br />The boundaries of the clearing limits shown on this plan shall be clearly flagged in the <br />field prior to construction. During the construction period, no disturbance beyond the <br />flagged clearing limits shall be permitted. The flagging shall be maintained by the applic- <br />ant/contractor for the duration of construction. <br />The ESC facilities shown on this plan must be constructed in conjunction with all clear- <br />ing and grading activities, and in such a manner as to insure that sediment and sediment <br />laden water do not enter the drainage system, roadways, or violate applicable water <br />standards. <br />The ESC facilities shown on this plan are the minimum requirements for anticipated site <br />conditions. During the construction period, these ESC facilities shall be upgraded as <br />needed for unexpected storm events and to ensure that sediment and sediment -laden <br />water do not leave the site. <br />The ESC facilities shall be inspected daily by the applicant/contractor and maintained as <br />necessary to ensure their continued functioning. <br />The ESC facilities on inactive sites shall be inspected and maintained a minimum of <br />once a month or within the 48 hours following a major storm event. <br />At no time shall more than one foot of sediment be allowed to accumulate within a <br />trapped catch basin. All catch basins and conveyance lines shall be cleaned prior to pav- <br />ing. The cleaning operation shall not flush sediment laden water into the downstream <br />system. <br />2014 Stormwater Management Manual for Western Washington <br />Volume // - Appendix A - Page 417 <br />
