Groundwater The applicant retained EGR to prepare an evaluation of groundwater impacts associated with the proposed expansion area. That evaluation, titled "Digital Model of Existing Excavation Site and New Expansion Area", dated June 2005, is attached to the application. The evaluation concluded that the proposed expansion of excavation (of the expansion area) could have an effect on groundwater resources in the immediate vicinity of the excavation. As accumulated water (rainwater and groundwater flowing into the excavations) is pumped from the excavations, the groundwater table could be lowered radially outward from the excavation edge. EGR noted that expansion of excavation in the area will not significantly affect municipal water supply system users in the area and that only one known significant groundwater user still exists in the vicinity of excavation site. The report concludes that that user is the plant nursery immediately to the north of the site that has already experienced most of the impact it will experience from present or expanded excavation. The evaluation concluded that mitigation may be required if other significant groundwater users exist in the vicinity of the excavation. Both Planning Commissions found there were conflicts with dust, noise, groundwater, wetlands and sensitive habitat, and agriculture. The Lane County Planning Commission additionally identified a conflict with flooding. The Eugene City Council finds that there are predicted discharge conflicts due to dust, noise, groundwater and flooding. (B) Potential conflicts to local roads used for access and egress to the mining site within one mile of the entrance to the mining site unless a greater distance is necessary in order to include the intersection with the nearest arterial identified in the local transportation plan. Conflicts shall be deternlined based on clear and objective standards regarding sight distances, road capacity, cross section elements, horizontal and vertical alignment, and similar items in the transportation plan and implementing ordinances. Such standards for trucks associated with the mining operation shall be equivalent to standards for other trucks of equivalent size, weight, and capacity that haul other materials; The primary road used for access and egress to the expansion area is Division Avenue, designated a Major Collector by the Eugene Arterial & Collector Street plan 1999. Division Avenue intersects with the nearest Major Arterial, Beltline approximately 200 feet easterly of the driveway. This is within one mile from the entrance. The record shows that the local roads used for direct access to or from the site are River Avenue, Division Avenue (two entrances), Beaver Street and Beaver-Hunsaker. Exhibits 28, 49. Numerous participants raised concerns about the impacts of current and continued traffic to and from the site, using these local roads. See, e.g. Exhibit 3, 7,14,16,20,21,22,23,27,275. The applicant's materials do not include a traffic impact assessment. The applicant asserts that no traffic impact assessment is needed because approval of the application would result in the Metro Plan diagram designation of the subject property being changed from one resource designation ("Agriculture") to another ("Sand and Gravel"). The applicant further asserts that '"approval of the application will not result in any additional traffic on any local roads and, consequently, will not significantly affect any transportation facility." Application, 8, 14-15. However, the applicant does not provide sufficient data documenting its current traffic impacts. This was pointed out by the City's Senior Transportation Analyst. Exhibit 29.
