Soil Treatments Most development projects require that soil be thoroughly compacted to produce the pad on which structures are placed. Unfortunately, this policy is completely at odds with proper preparation for the landscaping that will follow. The inevitable result is reduced on -site infiltration, excessive watering of landscaping, and increased herbicide -laden runoff into wetlands. Therefore, after construction has been completed and top soil has been spread, the soil should be tilled to a depth of 8 -10 inches. Ground Cover Environmentally sound landscaping calls for the use of native plants that do not require irrigation or the addition of nutrients. Therefore, the use of sod should be minimized as much as possible. Excessive use of water and the introduction of excessive fertilizers into our wetlands are not the only disadvantages of sod. In addition, this form of groundcover results in a tremendous yard -waste problem and added air pollution resulting from constant lawn maintenance. Vegetation The most effective approach to landscaping is one that uses our native plants that are adapted to this climate and which support our fauna. Significant stands of native vegetation within the project area should be identified and efforts made to preserve them. When restoring vegetation, we recommend use of native materials or other plants that require little irrigation or nutrient addition. Use of exotic, invasive species is strongly discouraged (eg., European Buckthorn, Norway Maple). See City Environmental Coordinator for lists of recommended and non - recommended species. Buffers Buffers, consistent with the City's Conservation Development Handbook, are a mandatory element for all developments and should be site - specific. They should be placed around all ecologically sensitive areas such as wetlands, prairie remnants, significant wildlife habitats, or high quality woodlands. These buffers may consist of undisturbed vegetation, restored prairies, trees, shrubs, or other plant materials consistent with the Vegetation guidelines above. Lighting All outdoor lighting should be both energy efficient and environmentally friendly. The citizens of Lino Lakes enjoy the night sky and the animals that fly through it. High intensity lighting or lighting that is allowed to scatter over a large area, diminishes the ability to view these amenities. Therefore, lighting shall be low - impact, low in stature, downwardly focussed, and no spill.
