Continued growth is expected to take place in 38 of Minnesota's 87 counties over the next 30 years. These growth projections suggest that more undeveloped land will be needed throughout the state for homes, businesses and industries, roads, and utilities. Recent studies of the growth corridor surrounding Minneapolis-St. Paul indicate that:
Ways to avoid or minimize the impacts of development on the natural environment do exist. Developing land with greater environmental sensitivity depends on early site assessment of natural resources, plans and construction techniques that avoid or minimally disturb plant and animal communities, and land management approaches that protect, maintain, or improve the "health" of natural resources.
This kind of development approach is economically sound: recent newspaper articles and scientific studies have shown that retaining wooded areas and some types of wetlands on property in developing areas actually increases property values. But, in addition, environmentally sensitive development brings much more that economic benefits in the form of higher property values. Many of today's home buyers perceive the incorporation of naturally vegetated areas into property design as a benefit that improves their quality of life. Testifying to the valuable role natural spaces play in people's lives, Minnesotans' have opted in the last year alone to protect over 7000 acres of open space by a variety of protection options (see references).
It takes a different way of thinking to develop an area with greater sensitivity to the natural environment, in other words, to work with the natural features of a site. This kind of approach requires that one:
Look at the kinds and locations of land and water habitats on the site in relation to each other and in relation to habitats off site. The transition area between land and water bodies, called the riparian zone, is especially important to maintain or restore. The riparian zone reduces the amount of sediment that enters the water and the plants in this zone take up excess nutrients and pollutants and help clean the water.
Contact the appropriate agencies or private consultants to have an assessment done of the water bodies and upland areas on site.
Explore development options to minimize impacts on wetlands, wooded areas, rivers, lakes, and other natural features, both on and off site.
Identify areas that have healthy, intact native plant communities with a natural resources assessment. These areas require more of a protection management strategy than habitats that require a more active management approach to be improved. Knowing how an area needs to be managed is helpful to determine the benefits and costs of making an area biologically richer.
Reduce amounts of impervious surface area in sidewalks, driveways, parking areas, and roads to provide more space to add vegetation.
Plant suitable species of varying heights to increase structural diversity on the site and to increase food and shelter available to wildlife.
Eliminate exotics wherever present, such as purple loosestrife or buckthorn. They out-compete native species and reduce the variety of species commonly found in an area.
Allow the many benefits realized by present and future generations to outweigh the up front costs of environmentally sensitive development.
Seek options to promote diversity and complexity with an environmentally sensitive development approach. The longer time frame permits the measurement of successes such as increases in biological diversity or a healthier environment.
Emphasize the importance of everyday actions to further improve environmental quality once an area is developed in an environmentally sensitive manner. Some important yard care practices that help to reduce individual acts of pollution include:
- Reducing the use of commercial fertilizers and herbicides
- Composting of yard waste for reuse as fertilizer in place of commercial fertilizers
- Controlling insects with integrated pest management (IPM) that uses biological pest controls or cautious applications of chemical pesticides
- Planting trees and shrubs in appropriate locations around the home or business to reduce energy demands for heating and cooling
- Disposing of hazardous waste in a responsible manner
A variety of land stewardship programs and land protection options exist to help the landowner manage or preserve land. See list of contacts below.
Consider clumped, higher density housing with areas set aside for open space such as parks or natural lands.
Increase alternative forms of transportation such as walking paths and bike trails, except in areas considered important for their biological diversity.
Place roadways outside wetlands, stands of trees, and grassland areas to the greatest extent possible to avoid dividing these natural areas into smaller patches, called fragmentation.
Avoid construction in areas of erodible soils or on slopes greater than 10%. Retain or create strips of vegetation, called filter strips, around all water bodies. The width of the filter strip varies, but 50 feet is considered a minimum width.
Protect wetlands from direct stormwater input through the construction of a two-celled basin system with a dedicated stormwater cell that receives water before the wetland does.
Restore degraded natural habitats such as wetlands and wooded areas through active management and consider creating green corridors, or linear vegetated connections, among these different natural areas.
Replant sites with native and other species best suited to the conditions of the location.
