Approval of this Erosion/Sedimentation Control (ESC) plan does not constitute an approval of permanent road or drainage design (i,e. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the app] icant/con tractor until all, -&h§tru-6if6u is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged in the field prior PLAN VIEW to construction, During the construction period, no disturbance beyond the flagged clearing limits , 4" rigid or 6"flexple shall be permitted. The flagging shall be maintained by the applicant/contmetor for the duration of NTS perforated pipe construction, ...... 4. The ESC facilities shown on this plan must be constructed in conjunction with all clearing and grading activities, and in such a manner as to insure that sediment laden water does not enter the plicable water standards, infiffratio or, drainage system or violate ap toot drain, n rage sump wf5olid lid 5. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall, be upgraded (i.e. additional sumps, relocation of ditches and silt fences, etc.) as needed for unexpected storm events. 6. The ESC facilities shall be inspected daily by the applicant/contractor and maintained as necessary PLAN VIEW to ensure their continued functioning. T Any area stripped of vegetation, including roadway embankments; where no further work is NTS anticipated or a period of 15 days, shall be immediately stabilized with the approved ESC methods overflow (i.e. seeding, mulching, netting, erosion blankets, etc.) splash bloc 8. Any area needing ESC measures, not requiring immediate attention shall be addressed within 15 perforated pipe days. 9, The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month 6- ........ or within the 48 hours following a storm event. 10. At no time shall more than one foot of sediment be allowed to accumulate within a catch basin. Nahhed suLk, All catch basins and conveyance lines shall be cleaned prior to paving., The cleaning operation shall not flush sediment -laden water into the downstream system, line mosh CS sump vdlmlid lid 11. Stabilized construction entrances and wash pads shall be installed at the beginning of constructionrw„ ropn and maintained for the duration of the project. Additional measures may be required to insure that A all paved areas are kept clean for the duration of the project. 12. During the time period of November I through March 3 1, all project disturbed areas greater than firer fabric 5,000 square feet, that are left unworked for more then 12 hours, shall be covered by one of the following cover measures: mulch, sod, or plastic covering, compacted backfill 13. Any permanent retention/detention facility used as a temporary settling basin shall be modified 6 with the necessary erosion control measures and shall provide adequate storage capacity. If the 4" rigid or is"Rexible permanent facility is to function ultimately as an infiltration or dispersion system, the facility shall 24" V perforated pip not be used as a temporary settling basin.

Where seeding for temporary erosion control is required, fast germinating grasses shall be applied 7 -3/4' at an appropriate rate (i.e., annual or perennial rye applied at approximately 80 pounds per acre). 15. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of two inches, 16, Management practices providing significant tree protection shall be provided per Section 22-1568 SECTION A (c) (6) (a-g) of FWCC.
