APPROVED JURISDICTIONAL DETERMINATION FORM U.S. Army Corps of Engineers This form should be completed by following the instructions provided in Section IV of the JD Form Instructional Guidebook. SECTION I: BACKGROUND INFORMATION A. REPORT COMPLETION DATE FOR APPROVED JURISDICTIONAL DETERMINATION (JD): /9/05 B. DISTRICT OFFICE, FILE NAME, AND NUMBER: Chicago District, Meyer Gravel, Lakemoor, JD Waters Edge, 006-008 C. PROJECT LOCATION AND BACKGROUND INFORMATION: Review area of approximately 00 acres at 05 W. IL Route 0 State: Illinois County/parish/borough: McHenry City: Lakemoor Center coordinates of site (lat/long in degree decimal format): Lat. 4.3377 N, Long. -88.388 W Universal Transverse Mercator: Zone 6, Y: 4687450.0849885; X: 39970.993866 Name of nearest waterbody: Fox River Name of nearest Traditional Navigable Water (TNW) into which the aquatic resource flows: None Name of watershed or Hydrologic Unit Code (HUC): Upper Fox (070006) Check if map/diagram of review area and/or potential jurisdictional areas is/are available upon request. Check if other sites (e.g., offsite mitigation sites, disposal sites, etc ) are associated with this action and are recorded on a different JD form. D. REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): Office (Desk) Determination. Date: /3/05 Field Determination. Date(s): 0/7/05 SECTION II: SUMMARY OF FINDINGS A. RHA SECTION 0 DETERMINATION OF JURISDICTION. There Are no navigable waters of the U.S. within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 39) in the review area. [Required] B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There Are no waters of the U.S. within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 38) in the review area. [Required]. Non-regulated waters/wetlands (check if applicable): Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: The review area contains three ponds that were excavated for gravel mining purpose, two larger ponds to the north (Ponds A and B) and one smaller pond to the south (Pond C). All mining activities terminated around 00. Each pond is surrounded by a berm. Ponds A and B were clearly excavated in non-hydric soil. They both are two former gravel pits that receive water from the adjacent upland. The berm surrounding these two ponds is very tall and there is no outlet to any water of the U.S. These two ponds are clearly isolated in the landscape. Pond C, the smaller pond to the south, was created as a wash pit. It is also entirely surrounded by a berm with no hydrologic connection to a water of the U.S. There is a wetland on the other side of the berm but a site visit revealed that the berm is high enough at all locations to prevent any water exchange between the pond and the wetland. No culverts were found to be present on the berm. While it is possible that Pond C may have been created in hydric soil, based on a review of historical USGS quadrangles, the mining disturbance started in the early 970s. A review of aerial photos from 988 to the present reveals that Pond C changed size and shape over the years depending on the mining activity occurring on the site. The berm separating the pond from the landscape outside of the mine appears clearly on all the aerial photos dated back to 988 and there is no evidence of any water exchange occurring on any of the aerial photos between the pond and the wetland on the other side of the berm. At the present time, and at least since the 970s, Pond C has been isolated in the landscape from the wetlands located south of the site. Pond C has begun to naturalize but clearly remains a remnant of mining activity. There is no evidence of any ecological or chemical nexus to a downstream water. SECTION III: CWA ANALYSIS E. ISOLATED [INTERSTATE OR INTRA-STATE] WATERS, INCLUDING ISOLATED WETLANDS, THE USE, DEGRADATION OR DESTRUCTION OF WHICH COULD AFFECT INTERSTATE COMMERCE, INCLUDING ANY SUCH WATERS (CHECK ALL THAT APPLY): Supporting documentation is presented in Section III.F.

REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): Office (Desk) Determination. Date: /5/05 Field Determination. Date(s): /3/05 SECTION II: SUMMARY OF FINDINGS A. RHA SECTION 0 DETERMINATION OF JURISDICTION. There Are no navigable waters of the U.S. within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 39) in the review area. [Required] B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There Are no waters of the U.S. within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 38) in the review area. [Required]. Non-regulated waters/wetlands (check if applicable): Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Eight wetland areas were delineated within the review area. - Wetland (0.03 acres) is an emergent wetland area located near the southwestern property boundary. - Wetland (.40 acres) is a farmed wetland area located near the southwestern property boundary. - Wetland 3 (0.7 acres) is an emergent wetland area located near the northern portion of the subject site, north of Lakewood Falls Drive. - Wetland 4 (0.89 acres) is an emergent wetland area in the north-central part that was previously farmed, but did not appear to have been in the recent past. - Wetland 5 (0.06 acres) is an emergent wetland area located within a pipeline right-of-way along the western property boundary in the northern portion of the project area. - Wetland 6 (.09 acres) is located in the northwestern corner of the project area and consists of an emergent wetland area. - Wetland 8 (5.4 acres) is located in the northeastern corner of the project area and consists of an emergent wetland area. - Wetland 9 (0.75 acres) is located in the northeastern portion of the project area and consists of an emergent wetland area. Note that Wetland 7 is a wetland that was identified during the delineation but it is outside of the review area; therefore, no jurisdictional determination is being made on this one. All 8 wetlands were found to be depressional areas with no outlet to a downstream water. They are isolated in the landscape in that they are surrounded by upland and are located approximately 4,800 feet from the nearest tributary.

APPROVED JURISDICTIONAL DETERMINATION FORM U.S. Army Corps of Engineers This form should be completed by following the instructions provided in Section IV of the JD Form Instructional Guidebook. SECTION I: BACKGROUND INFORMATION A. REPORT COMPLETION DATE FOR APPROVED JURISDICTIONAL DETERMINATION (JD): //05 B. DISTRICT OFFICE, FILE NAME, AND NUMBER: Chicago District, First Industrial Realty Trust JD, LRC-05-69 C. PROJECT LOCATION AND BACKGROUND INFORMATION: A 5-acre review area located at 365 North Avenue. State: Illinois County/parish/borough: DuPage City: Carol Stream Center coordinates of site (lat/long in degree decimal format): Lat. 4.90359 N, Long. -88.0847 W. Universal Transverse Mercator: Zone 6 Name of nearest waterbody: Klein Creek Name of nearest Traditional Navigable Water (TNW) into which the aquatic resource flows: None Name of watershed or Hydrologic Unit Code (HUC): Des Plaines (070004) Check if map/diagram of review area and/or potential jurisdictional areas is/are available upon request. Check if other sites (e.g., offsite mitigation sites, disposal sites, etc ) are associated with this action and are recorded on a different JD form. D. REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): Office (Desk) Determination. Date: /7/05 Field Determination. Date(s): 0/0/05 SECTION II: SUMMARY OF FINDINGS A. RHA SECTION 0 DETERMINATION OF JURISDICTION. There Are no navigable waters of the U.S. within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 39) in the review area. [Required] B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There Are no waters of the U.S. within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 38) in the review area. [Required]. Non-regulated waters/wetlands (check if applicable): Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Wetland, approximately.7 acres on site, consists mostly open water in the northwest portion of the review area. Wetland is connected to a ditch that was constructed in non-hydric soil, apparently in the 970s. Old project plans provided by the current owner show that the site is pitched in the middle of the ditch, making it flow both east and west. On the western side of the pitch, water flows west into Wetland and on the east side of the pitch, water flows into a storm sewer system on the northeast portion of the review area. There is no evidence that this ditch carries relatively permanent water and given the pitch and its length (approximately,460 linear feet) it is very unlikely that water from Wetland reaches the storm sewer system. Wetland collects water from the adjacent upland and no outlet to a downstream water was found, making it isolated in the landscape. This finding is supported by all the internal resources. Finally, note that the nearest mapped tributary is located over 5,000 feet away. Wetland, approximately 0.7 acres, is located within the northeast portion of the project area and consists of a small depressional wooded wetland. Wetland is entirely surrounded by upland and does not have any hydrologic connection to a downstream water. SECTION III: CWA ANALYSIS E. ISOLATED [INTERSTATE OR INTRA-STATE] WATERS, INCLUDING ISOLATED WETLANDS, THE USE, DEGRADATION OR DESTRUCTION OF WHICH COULD AFFECT INTERSTATE COMMERCE, INCLUDING ANY SUCH WATERS (CHECK ALL THAT APPLY): which are or could be used by interstate or foreign travelers for recreational or other purposes. from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. which are or could be used for industrial purposes by industries in interstate commerce. Interstate isolated waters. Explain:. Other factors. Explain:. Identify water body and summarize rationale supporting determination:. Supporting documentation is presented in Section III.F. Prior to asserting or declining CWA jurisdiction based solely on this category, Corps Districts will elevate the action to Corps and EPA HQ for review consistent with the process described in the Corps/EPA Memorandum Regarding CWA Act Jurisdiction Following Rapanos.
Provide estimates for jurisdictional waters in the review area (check all that apply): Tributary waters: linear feet width (ft). Other non-wetland waters: acres. Identify type(s) of waters:. F. NON-JURISDICTIONAL WATERS, INCLUDING WETLANDS (CHECK ALL THAT APPLY): If potential wetlands were assessed within the review area, these areas did not meet the criteria in the 987 Corps of Engineers Wetland Delineation Manual and/or appropriate Regional Supplements. Review area included isolated waters with no substantial nexus to interstate (or foreign) commerce. Prior to the Jan 00 Supreme Court decision in SWANCC, the review area would have been regulated based solely on the Migratory Bird Rule (MBR). Waters do not meet the Significant Nexus standard, where such a finding is required for jurisdiction. Explain:. Other: (explain, if not covered above):. Provide acreage estimates for non-jurisdictional waters in the review area, where the sole potential basis of jurisdiction is the MBR factors (i.e., presence of migratory birds, presence of endangered species, use of water for irrigated agriculture), using best professional judgment (check all that apply): Non-wetland waters (i.e., rivers, streams): linear feet width (ft). Wetlands: Wetlands and total 3.4 acres. Provide acreage estimates for non-jurisdictional waters in the review area that do not meet the Significant Nexus standard, where such a finding is required for jurisdiction (check all that apply): Non-wetland waters (i.e., rivers, streams): linear feet, width (ft).
