c. Avoid ocher wecland fill, exceoC for che rainimura necessary co fill in Block 1, Loc 4, in an essentially isolacea pockec separate from che larger marsh. This pocket does not show on che National Wecland Inventory map but does appear on che soil survey as an isolated area of Glencoe soil. The wecland pocket (shown on che accached map) is separated from che main marsh by a ridge of upland soil (shown on che county soil sun/ey and verified by field inspection) with only an old, dry ditch connection to convey high water. This wecland pockec covers approximately an acre of grassy, type 2 wecland, with a wooded fringe. Your grading plan shows chat che house pad in Loc 4 may require a very small area of Chis wecland. Although che nationwide permit would allow up co an acre of fill* or grading in chis wecland, we suggest Chat you minimize filling and other adverse disturbance there. (On chis site, only chis small wecland qualifies for this nationwide permit. The ocher wecland require individual pennies for residential or other fill and grading.) If you, or a subsequent landowner, wishes to excavate a wildlife pond in Chis area, we can make some specific suggestions. This wecland encroaches slightly into Loc 5. d. Keep other fill and gr-jmg around che main marsh above elevation 934. Mr. Yanca did not mark che entire wecland, but he did verify that che wecland generally seems Co go abovo elevation 932 but not quite to elevation 934. Your grading plan does not show any fill or grading below chis elevation, aside from the two areas discussed above chat would be covered by nationwide permits and the area in Block 2, Loc 1, chat we suggest you do not fill. Some of che area shown as old fill in che county soil survey (see attached map) still appears to be wecland, with saturated hydric soils and wecland vegetation. Perhaps these areas were low, wet spots partly filled with hydric soil chat has since subsided and taken on a more natural wecland character. If you plan to fill or grade below 934 in these areas, we would require a delineation of che entire wecland. We could do this delineation ourselves, although it would be several weeks before we could schedule it, or you could hire a qualified consultant to do the delineation and submit a report chat would be subject to our review and approval. e. Clean excavation of che area shown in Block 1, Lots 5 and 8, would not require a Department of che Army permit if the excavated material is placed on an upland area and if no ocher fill or grading is involved in che excavation. (This excavation would probably receive only partial mitigation credit, if any, for wecland fill authorized under a Department of the Army permit because the excavated area appears co be all wecland. The excavation would only convert one wecland type to another, rather chan create or expand an existing wetland.) If these changes are acceptable and no orh-r .'»■ anges chat might involve wecland fill are necessary, we do not require any fui review of your project or processing of your application. The nationwide permits for che fill described in sections b and c are already in effect. If you wish to apply for a permit to place fill in Block 2, Loc 1, or in any other wecland areas adjacent to Wecland 27-912W, you must apply for an individual permit for che entire project. (Your current application covers only che proposed fill in Block 2, Lot 1.) This determination covers only che project referenced above. If the design, location, or purpose of che work changes, you should contact us to make sure che work would not result in a violation of Federal law. Our telephone number is (612) 220-0375.
