Idyllvale Shores – Conservation Design Master Plan October 2024 Civil Methods, Inc.Page | 6 development. Instead, the project can focus on mitigating the spread of EAB and planting native tree species to replace the lost ash trees. By proactively addressing invasive species and the emerald ash borer, the Idyllvale Shores project demonstrates a commitment to environmental responsibility and contributes to the preservation of the region's natural ecosystems. 3.4 WOODLAND PRESERVATION The Idyllvale Shores project prioritizes the preservation of the existing woodland on the development site. While some tree removal will be necessary to accommodate the proposed development, it's important to note that many of the trees slated for removal are already diseased or dying. These trees pose a safety hazard and would likely need to be removed regardless of the development. Moreover, much of the project area will remain undisturbed, with extensive woodland preserved on the site's periphery. This not only helps to maintain the natural character of the development but also provides a valuable buffer between the residential areas and the surrounding environment. By carefully considering the health of existing trees and minimizing the impact on the overall woodland ecosystem, the Idyllvale Shores project demonstrates a commitment to environmental stewardship and ensures the long-term sustainability of the development. 3.5 WETLAND PRESERVATION The Idyllvale Shores project initially anticipated potential wetland impacts due to the proposed development, specifically for an additional residential lot originally envisioned at the eastern end of the project area. That was a responsible alternative, but due to regulatory obstacles combined with a fundamental desire to preserve the natural resources of the site, design modifications were completed to avoid any significant wetland disturbance. The current design preserves the existing wetlands and minimizes our ecological footprint. This approach both protects the wetlands and safeguards the surrounding natural habitat, including valuable tree stands. Additionally, the project incorporates infiltration basins with vegetation to mitigate water quality impacts and reduce the impact on wetlands. 3.6 MITIGATION OF NEGATIVE IMPACTS The Idyllvale Shores project prioritizes the mitigation of negative environmental impacts. One significant mitigation strategy involves the installation of infiltration basins, which will capture, infiltrate, and treat stormwater runoff before it reaches Lake Minnetonka. These basins will help to reduce the volume and rate of flow, preventing downstream flooding and preserving the health of the wetlands. 121
