Record of Decision — Riverstone Addition Environmental Assessment Worksheet 11. Historic Resources. A search of the Minnesota Archaeological Inventory and Historic Structures Inventory did not identify archaeological sites or historic structures known to exist in the project vicinity. The project is not expected to affect historic resources. 12. Visual Resources. There are no scenic views or vistas on or adjacent to the project area. Substantial effects on visual resources are not anticipated in conjunction with project development. 13. Noise. A Noise Study predicted noise levels at 19 receptor locations. The modeled noise level at one of the receptor locations exceeded Minnesota NAC-1 noise standards for daytime hours (Appendix B). The noise study lists potential remedies for this situation. 14. Transportation. The traffic to be generated by the proposed project does not raise capacity or safety concerns. Traffic generated by the project will have little effect on the regional transportation system. Intersections surrounding the site will continue to operate at acceptable levels of service with the addition of traffic generated by the proposed project. The Updated Traffic Study for the project is included in Appendix C. B. Cumulative Potential Effects Minnesota Rules 4410.1700 Subp. 7 (B) indicates the second factor the City must consider is "whether the cumulative potential effect is significant; whether the contribution from the project is significant when viewed in connection with other contributions to the cumulative potential effect; the degree to which the project complies with approved mitigation measures specifically designed to address the cumulative potential effect; and the efforts of the proposer to minimize the contributions from the project." The City's findings are set forth below. Projects typically combine to produce cumulative effects on municipal resources like water and wastewater treatment. The City of Ramsey has planned for growth and increased capacity to address these cumulative effects. The proposed project will implement approved mitigation measures and be consistent with land use policies for areas served by municipal sewer and water. Cumulative effects of suburban development on natural resources may include the loss of agricultural land and the loss and fragmentation of wildlife habitat. Surface water runoff from the project area will infiltrate into the soil or be treated in ponds prior to discharge to the Mississippi River. Stormwater regulations administered by multiple agencies and water quality BMPs are expected to minimize cumulative effects of post -development runoff on downstream waters. C. Extent to Which the Environmental Effects are Subject to Mitigation Minnesota Rules 4410.1700 Subp. 7 (C) indicates the third factor the City must consider is the "extent to which the environmental effects are subject to mitigation by ongoing public regulatory authority." The City's findings are set forth below. Environmental effects on cover types, shorelands, floodplains, water quality, and traffic are subject to additional approvals and/or mitigation through requirements of local, state, and federal regulations, ordinances, management plans, and permitting processes. The following permits and approvals are required for the project addressed under the EAW. These permitting and approval processes will provide additional opportunity to require mitigation. 7
