5) Middle Creek Office'Ibpsoil Stockpile -includes some 0.5 acres approximately 500 <br />• feet southwest of the Middle Creek Office exemption. `itre combination of slope, <br />vegetative cover, and negative drainage preclude sediment reaching Foidel Creek. <br />6) Homestead Ditch Exemption ZWo -Includes some 25 acres of 1986 seeding upslope <br />of the Homestead Irrigation Ditch. Zt~e area was seeded with fast establishing <br />gl-aacaa~ ripped, and contour furrowed. Flow is filtered by vegetation and a 1600 <br />ft silt fence, which is to be inspected/maintained semi-annually until the fence <br />is removed (approved under MR 92-16). ~Y~is exemption was originally approved as <br />part of the adequacy response to TR 86-1. <br />7) Access Road Strip -includes some 1.0 acre of 1986 seeding wcet of the approved <br />permanent access road to a stock porn. Approximately 60 percent of the drainage <br />from this parcel drains to a low area adjacent to the road, with no opportunity <br />for positive drainage from that point. Zhe remaining 40$ flows to the north <br />along the aoce_cs road, and would be wntrolled by a rock filter. <br />8) Office Area Seeding - includes some 2.0 Acres on the floodplain immediately <br />• adjacent to the Middle Creek Office building. Due to a combination of slope <br />(less than 2~), vegetative cover, and the parcel's position in relation to the <br />floodplain, CYCC feels that the current vegetative filter is sufficient in <br />conjunction with the existing perimeter Swale aryl depression which collects flow <br />frwn the area. Flow not collected by the Swale breaks back to the ditch <br />associated with SAE #4. <br />9) Ditch H-1 Area -includes some 2.0 acres immediately below Ditch H-1. Due to the <br />combination of slope, vegetation along the border acting as a filter, and coarse <br />surface fragments, CYGC feels that the current vegetative filter is sufficient. <br />Samples collected during a precipitation event indicate that this is indeed the <br />SAE'S #8 and #9 -Office Area Seeding and Ditch H-1 Area; <br />(Yab samples were collec.-ted above and below each of the two small area exemptions <br />during the tail end of a 6 hour plus duration rainfall event, and runoff was observed <br />during sampling. Sample locations are shoran on Map 4A. Sites 703 and 704 are upstream <br />• aryl downstream of SAE #9 respectively, and lie above the <br />MR 92-16 2.05-21(a) Revised 11-04-92 <br />
