Approval af this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainc1ge design (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The irnplementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approve<J. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape ( or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 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 as needed for une:<pected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g .. seeding, mulching, plastic covering, etc.). 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. wet 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. 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. 1·1. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. A PORTION of the S. W. 1 / 4, SECTION 32, TOWNSHIP 23 N., RANGE 5 E., W.M. PERMANENT SEEDING NOTES 1. Seeding should be done immediately after final shaping if completed during the periods of April 1 through June 30 and September 1 through October 15 (if planted between July 1 and August 31 irrigation may be required). Sites which cannot be seeded during this time period should be protected until the next seeding period with mulch. 2. Permanent vegetation may be in the form of grass seed mixtures, sod, or wetlands seed/tuber mixtures. Seed establishment shall include the use of supplemental materials, such as mulch. 3. Site preparation -install all required surface water control measures. 4. Seedbed preparation may include the following: a.) If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and re-spread it over the finished slope and roll it to provide a firm seedbed. b.) If construction fills have left soil exposed with a loose, rough, or irregular surface, track walk up slope. c.) If cuts or construction equipment have left a tightly compacted suriace, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). The seedbed should be firm with a fairly fine surface after roughening. 5. Fertilization. -in general, 10-20-20 N-P-K fertilizer at a rate of 90 lbs./acre. Developments adjacent to water bodies and wetlands must use slow release low-phosphorus fertilizer (typical 3-1-2 N-P-K). 6. "Hydroseeding" applications with approved seed-mulch-fertilizer mixtures may also be used, as long as tackifier is included. 7. Seeding -apply appropriate mixture to the prepared seedbed at a rate of 120 lbs./acre. Cover the seed with topsoil or mulch no deeper than 1/2 inch. 8. Inspect seeded areas for failure and make necessary repairs and re-seedings immediately. a.) If vegetative cover is inadequate to prevent rill erosion, overseed and fertilize in accordance with soil test. b.) If a stand has less than 40% cover, reevaluate choice of plant materials and quantities of lime and fertilizer. Re-establish the stand following seedbed preparation and seeding recommendations, omitting lime and fertilizer in the absence of soil test results. POLYETHYLENE CAP PROVIDE ADEQUATE STRAPPING STABILIZED CONSTRUCTION ENTRANCE MAINTENANCE STANDARDS 1. QUARRY SPALLS (OR HOG FUEL) SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS. 2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, ANO WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND. 3. ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED ____- IMMEDIATELY BY SWEEPING. THE SEDIMENT COLLECTED BY SWEEPING SHALL BE REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DOWN THE STREET, EXCEPT WHEN SWEEPING IS INEFFECTIVE AND THERE IS A THREAT TO PUBLIC SAFETY. IF NECESSARY TO WASH THE STREETS, THE CONSTRUCTION OF A SMALL SUMP SHALL BE CONSIDERED. THE SEDIMENT WOULD THEN BE WASHED INTO THE SUMP. 4. ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY. 5. IF VEHICLES ARE ENTERING OR EXITING THE SITE AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S), FENCING (SEE SECTION D.4.1) SHALL BE INSTALLED TO CONTROL TRAFFIC. AS PER KING COUNTY ROAD STANDARDS, DRIVEWAYS SHALL BE PAVED TO THE EDGE OF R-0-W PRIOR TO INSTALLATION OF IHE CONSTRUCTION ENTRANCE TO AVOID DAMAGING OF THE ROADWAY IT IS RECOMMENDED THAT THE ENTRANCE BE CROWNED SO THAT RUNOFF DRAINS OFF THE PAD .

Approval af this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainage design (e.g. 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 applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior so as to ensure that the transport of sediment to surface waters, minimized. to or in conjunction with all clearing and grading drainage systems, and adjacent properties is 5. The ESC facilities shown on this plan are the minimum construction period, these ESC facilities shall be upgraded account for changing site conditions (e.g. additional sump requirements for anticipated site conditions. During the as needed for unexpected storm events and modified to pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin<) the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic cov,iring, etc.). 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9, The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. wet 10.

If the facility is to function ultimately as an A PORTION of the S.W. 1/4, SECTION 32, TOWNSHIP 23 N., RANGE 5 E., W.M. PERMANENT SEEDING NOTES 1. Seeding should be done immediately after final shaping if completed during the puriods of April 1 through June 30 and September 1 through October 15 (if planted between July 1 and August 31 irrigation may be required). Sites which cannot be seeded during this time period should be protected until the next seoding period with mulch. 2. Permanent vegetation may be in the form of grass seed mixtures, sod, or wetlands seed/tuber mixtures. establishment shall include the use of supplemental materials, such as mulch. 3. Site preparation -install all required surface water control measures. 4. Seedbed preparation may include the following: Seed a.) If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and re-spread it over the finished slope and roll it to provide a firm seedbed. b.) If construction fills have left soil exposed with a loose, rough, or irregular surface, track walk up slope. c.) If cuts or construction equipment have left a tightly compacted surface, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). The seedbed should be firm with a fairly fine surface after roughening. 5. Fertilization -in general, 10-20-20 N-P-K fertilizer at a rate of 90 lbs.I acre. Developments adjacent lo water bodies and wetlands must use slow release low-phosphorus fertilizer (typical 3-1-2 N-P-K). 6. "Hydroseeding" applications with approved seed-mulch-fertilizer mixtures may also be used, as long as tackifier is included. 7. Seeding -apply appropriate mixture to the prepared seedbed at a rate of 120 lbs./acre. Cover the seed with topsoil or mulch no deeper than 1/2 inch. 8. Inspect seeded areas for failure and make necessary repairs and re-seedings immudiately. a.) If vegetative cover is inadequate to prevent rill erosion, overseed and fertilize in accordance with soil test. b.) If a stand has less than 40% cover, reevaluate choice of plant materials and quantities of lime and fertilizer. Re-establish the stand following seedbed preparation and seeding recommendations, omitting lime and fertilizer in the absence of soil test results.
