14. Page 23, Visual. Given the proximity of the development to a sensitive natural area, <br />development lighting is an important consideration, especially since tall multistory buildings are <br />proposed. Animals depend on the daily cycle of light and dark for behaviors such as hunting, <br />migrating, sleeping, and protection from predators. Light pollution can affect their sensitivity to <br />the night environment and alter their activities. In addition to the undesirable effects of upward <br />facing lighting, the hue of lights can also affect wildlife. LED lighting has become increasingly <br />popular due to its efficiency and long lifespan. However, these bright lights tend to emit blue <br />light, which can be harmful to birds, insects, and fish. The DNR recommends that any projects <br />using LED luminaries follow the MnDOT Approved Products for luminaries, which limits the <br />Uplight rating to 0. A nominal color temperature below 2700K is preferable for wildlife, and so <br />we recommend choosing products that have the lowest number for backlight and glare (all <br />approved products should already be 0 for Uplight). <br />15.

DNR recommends that dust suppressants containing chloride not be <br />used in areas that drain to public waters. <br />Thank you again for the opportunity to review this document, and please let me know if you have any <br />questions. <br />Sincerely, <br />Melissa Collins <br />Regional Environmental Assessment Ecologist I Ecological and Water Resources <br />Minnesota Department of Natural Resources <br />1200 Warner Road <br />St. Paul, MN 55106 <br />Phone: 651-259-5755 <br />Email: melissa.collins@state.mn.us <br />CC: Lauren Grouws, North Oaks Company, LLC <br />Equol Opportunity Employer <br />4 <br />
