the on-site mitigation project. (#163) 4. Within the prairie habitat inside the southeast field, the ratio of native dominant and sub- dominant plant species to non-native dominant and sub-dominant plant species is roughly the same as that in the Willow Creek Natural Area's high quality wet prairie habitat. (#99, #163) 5. Construction of phase 1 ofHyundai's development began in 1996. Site maps show that buildings associated with phase 1 are approximately 600 feet from the wetlands in the southeast field. These maps also show that the stormwater treatment facility is approximately 300 feet from the nearest wetlands in the southeast field. (Pfeiffer, Attachment 6--12/17/96 PC packet) 6. Hyundai's on-site mitigation has been constructed and has altered hydrology on the site. The grading plan for the mitigation area was altered to provide for a hydrologic connection between the mitigation area and the wetlands in the southeast field. Further, the Corps permit that authorized the mitigation project included a special condition (#4) that "requires the permittee to maintain the hydrological connection between the wetlands in the northwest corner of the site and those downslope at all times." (#146, #175, Monical-12/17/96 PC packet) 7. According to the Corps of Engineers "the primary source of hydrology to the wetlands was determined to be precipitation (SRI/Shapiro Technical Memorandum to Barbara Priest dated October 23, 1995). This assessment appears to be confirmed by both the drainage patterns, and the pattern of the wetlands on the landscape." (Monical-12/17/96 PC packet) 8. SUrveys were conducted on the Hyundai site for Oregon chub and salmonid species and none were found. No survey was conducted for other aquatic species, amphibious species or other water-dependent species. (Pfeiffer--12/17/96 PC packet) 9. A population of Erigeron decumbens var. decumbens exists 200 meters (off-site) to the east of the E. decumbens plants on the Hyundai site. (#167) 10. Geo-technical studies conducted by GeoEngineers in 1995 state that no fill was detected south of the east-west ditch in a study that involved 25 test pits and 9 deeper borings. All fill was found north of the east-west ditch, in the area now occupied by stormwater treatment facilities. (Reed, #99) The following information was received from the Oregon Division of State Lands on March 7, 2000 (Patti Caswell, ODSL, personal conversation): Hyundai's wetland fill permit from the Oregon Division of State Lands for Phases 1 and 2 expired on January 28, 1999. The US Army Corps of Engineers permit is still valid, but will expire on Hyundai Site Ordinance, Exhibit C (Refinement Plan Amendment Findings) Page 3
