Environmentally Beneficial Landscaping ------- ost oavmgs Pollution Prevention source Conservation National Recognition ------- What Is GreenScapes? Roads and highways, golf courses and ski resorts, commercial buildings and industrial sites—the widespread use of economically and / environmentally costly landscaping is • everywhere. By simply changing these landscapes to "GreenScapes," you can save money and prevent pollution. \ j The U.S. Environmental Protection // Agency's (EPA's) GreenScapes program // provides cost-efficient and environmen- tally friendly solutions for large-scale landscaping. Designed to help preserve natural resources and prevent waste and pollution, GreenScapes encourages companies, government agencies, and other entities to make more holistic deci- sions regarding waste generation and disposal and the associated impacts on land, water, air, and energy use. By focusing on the "4 Rs"—reduce, reuse, recycle, and rebuy—you can help improve both your bottom line and the environment. ------- Why Is GreenScaping Important? Think about some of the large-scale land uses in the United States—shopping and retail cen- ters; recreational facilities such as golf courses, ski resorts, amusement parks, public gardens; roads and highways; abandoned industrial sites such as brownfields; college and universi- ty campuses; and military installations. Think about the millions of tons of materials that are hauled away, buried, or burned each day from landscaping and groundskeeping operations— trees, shrubs, brush, lumber, asphalt, and con- crete, just to name a few. Also, consider the millions of gallons of water, pesticides, fuels, and oils used each and every day in landscap- ing. The costs of these materials—both eco- nomic and environmental—can be easily reduced or eliminated with updated landscap- ing methods. What Can You Do? Understanding the economic and environmen- tal benefits of saving resources and preventing waste and pollution is key to bringing positive changes to your operations and surroundings. These changes can be made gradually. Set a combination of short- and long-term goals— activities that can be performed in a few weeks paired with actions that can be imple- mented later for future gains. Even small improvements can create a huge ripple-effect- not only on your site, but throughout your industry and the environment. Focus on the 4Rs: • Reduce • Reuse • Recycle • Rebuy ------- Reducing the production of waste is the first and most important step towards efficient materials use; When planning a new landscape design or updating a current one, avoid prod/ ucts that require frequent replacement or regu- lar maintenance to reduce future waste. Durable products will long outlast those of • lesser quality, reducing future waste generation and the need to purchase new or replacement^. products. Try some of the following waste reduction suggestions: • Reduce or eliminate plastic silt fencing and substitute with blankets, berms, and filter- socks made of compost, for erosion con- trol and reduction of nonpoint source pol- lution. Compost provides superior filtration and erosion prevention/control, is more easily installed and maintained, and does not require energy-intensive removal or disposal from the site once the job is completed. • Reduce nonpermeable hardscape wherev- er possible to minimize rainwater runoff and erosion. Consider parking areas or paths made from mulch or gravel. Where hard surfaces are necessary, use asphalt 7.. This filter berm made from compost demon- strates how well the organic material helps retain runoff in comparison to a typical silt fence in the lower portion of the photo. ------- containing recycled tires—the surface will last longer and require less maintenance, • Switch from benches, boardwalks, and signs made from wood to long-lived plas- tic lumber. Structures made from recov- ered plastic material do not require routine upkeep—saving paint, solvent, and labor costs. Plastic lumber also lasts many years longer than wood—greatly reducing maintenance and replacement costs. • Conserve water through "Xeriscaping." Plant vegetation that is not only drought- resistant, but indigenous to a region's soil and climate conditions. Once established, these native plants can survive with little care or water. Add compost to the soil to help improve water absorption and reten- tion and further reduce water require- ments. Native plants are also more pest- resistant and healthier, thus requiring less Compost - An On-Par Alternative The soil on the North Shore Country Club (Glenview, Illinois) golf course had elevat- ed sodium levels—too high to maintain quality turf. Standard procedure called for the installation of a well to solve this problem, but that solution came with a quarter million dollar price tag. With o little research, North Shore found compost to be the economical alternative to enhance the quality of its soil. ------- fertilizers and pesticides. Long-lived, "" hardier vegetation can save money by lowering labor costs and money spent on maintenance supplies. • Produce less green waste by limiting fertik' izer and water use—this will save you money and maintenance time due to slower plant growth. Less landscape maintenance translates to fewer hours of equipment operations, saving fuel, mainte- nance, labor, and emissions and increas- ing equipment longevity. • All pesticides are toxic to some degree- spot treat whenever possible. In most cases, treating an entire region with pesti- cides isn't necessary if the problem is confined to specific areas. Treating more than necessary is wasteful and can be environmentally damaging. For similar rea- sons, consider using organic fertilizers instead of chemical ones, • Start or increase onsite composting of clip- pings, trimmings, leaves, and food scraps. Compost contributes vital nutrients and dis- ease-suppressing properties to the soil, reducing the need for chemical fertilizers or pesticides. Compost is also an excellent soil amendment for seeding grass and young plants, reclaiming nutrient-poor soil, and preventing erosion. Compost can be made cheaply and easily on site. In addi- tion, diverting organic material to a com- post pile can prevent the production of the greenhouse gas methane that normally occurs when this waste is buried in landfills. • Top-dress your turf with compost—this can decrease fertilizer use by up to 50 percent and decrease irrigation needs by increasing water absorption and retention. • Place mulch over a plant's root zone to reduce moisture evaporation and conserve water. Mulch also inhibits weed growth. Save money and make your own mulch by chipping wood wastes generated from your site. ------- • Set mower blades higher. Longer top growth means deeper roots, making the grass more durable in drought conditions and better able to fight weeds and dis- eases without pesticides. •Grasscycle—leave grass clippings in place {don't bag) when mowing. The clippings quickly decompose and release valuable nutrients into the soil, reducing the need for fertilizers by 15 to 25 percent. This activity also reduces water use, grass dis- posal, and maintenance costs. Grass trim- mings do not cause thatch. • Use vegetation outside to reduce indoor heating and cooling needs. Deciduous trees planted appropriately along the south sides of buildings can reduce air conditioning costs by up to 20 percent; in winter they allow the sun's rays to warm --| buildings. Coniferous trees planted to block prevailing northwest winter winds can reduce heating costs. Trees planted to shade paved areas reduce the summer "heat-island" effect that makes parking . lots so inhospitable. ------- XYeuse Reuse serves as another key component to environmentally beneficial landscaping. Many items can be reused effectively without adding / much time or energy. Try some of the following reuse tips: • Chip woody shrubs and tree clippings into mulch that can be applied to the land- scape. This activity saves money on dis-N posal costs while adding the benefits of mulch, such as.moisture retention, weed prevention, and erosion control. • Return wooden pallets to your supplier whenever possible. Nonreturnable pallets can be chipped and used on site for mulch or compost. • Donate healthy plants to community gar- dens, schools, churches, or other local nonprofit organizations when reconfiguring or removing trees and shrubs from your landscape. • Use alternative sources of irrigation water such as gray water, reclaimed water, and collected rain water. These options save water and money while helping to reduce runoff, erosion, and nonpoint source pollution. ------- A "Growing" Plastics Recycling Business Agri-Plas, Inc., an agricultural plastic recycler in Oregon, processes tons of dis- carded plastics from the agricultural and nursery industries each year. The company collects trays, pots, and greenhouse films from about 100 nearby nurseries and picks up baling twine and plastic agricul- tural chemical containers from local farm- ers and growers. Agri-Plas provides the recovered plastic to end users that make new products for the nursery and automo- tive industries. Recycle Creating products from recycled materials saves energy and resources, and can often generate revenue. Try some of the following recycling suggestions: • Send clippings, trimmings, and leaves that cannot be composted on site to a local composting facility in exchange for finished compost at a discounted price or fee. • Save bedding trays and plant containers from annuals and other greenery and send •them to a recycler for processing. • Place recycling receptacles next to trash receptacles. • Collect and recycle the used oil and tires from your vehicles and equipment. 8 ------- /XVebuy /Rebuying means re-thinking your purchasing habits. Look for products that meet your / needs but have a better environmental profile / than your current.product purchases. Consider biobased, recycled content, and other environ- mentally preferable aspects in your purchasing decisions. Recycled products, for example, are often more durable than those made with vir1, gin materials, saving money and raw materials v over time. Rebuying is key to sustaining recy- cling markets, and it aids in the development of technology that conserves resources and prevents waste. You can work with your man- agers, clients, suppliers, and vendors to identi- fy and establish specifications to purchase var- ious recycled-content products. Biobased products—products other than food or feed that utilize biological products or renewable domestic agricultural (e.g., plant, animal, and marine) or forestry materials—should also be given preference1. Try these rebuy tips: • Use blankets and berms made of com- post to minimize or eliminate soil erosion, runoff, and nonpoint source pollution. Compost is both a biobased product and a recycled product because it is made from recycled organic waste materials. . Compost also makes an. excellent air filter media for volatile organic compounds (VOCs). 1. As defined under Executive Order 13101 and Executive Order 13134. ------- • Select plastic lumber made from recycled bottles and bags for benches and other outdoor structures. Plastic lumber is an extremely durable material that lasts longer and requires less maintenance than traditional wood, realizing significant cost savings for you over the life of the materi- al. The National Park Service currently has more than a dozen projects planned with plastic lumber. • Use high efficiency lighting for roadways, parking lots, security, and landscaping. • Purchase biodiesel and biobased lubri- cants for your equipment. Besides being better for the environment, keeping less hazardous materials on your site reduces management costs and possibly insur- ance costs. • Incorporate rubberized asphalt (made from recycled tires) for walking, running, bike, or cart paths—it extends the life of trails and reduces the frequency of repairs. This walking path at the Earvin "Magic" Johnson Recreation Area in Los Angeles County is made from rubberized asphalt, which is more resilient than traditional asphalt. 10 ------- / * Use recycled glass for golf course bunker I / sand, beach sand, or filter media. I/ * • Rethink your pesticide use through Integrated Pest Management (IPM). IPM reduces the risk from pesticides, and in / some cases, reduces the amount of pesti- cides needed. IPM is based on a combi- nation of techniques such as biological j control, habitat manipulation, and modifi- cation of cultural practices, often including steps you can take before you ever encounter a pest problem. If pesticides become necessary, they are selected and applied in ways that minimize risks to human health and the environment and remove only the target organism. Join the Alliance—Help Make a Difference! There's a lot that can be done to advance green landscaping, but we can't do it alone—we need help from industry. The knowledge and experience of those who have "been there, done that" is invaluable. To help foster these important partnerships, we estab- lished the GreenScapes Alliance. The Alliance combines government and industry into a powerful, unified influence over the reduction, reuse, and recycling of materials and resources in land use activities that include 4 million miles of roadside landscaping, land revitalization, and the construction and maintenance of office complexes, golf courses, and parks in government and industry across the nation. More than 100,000 businesses are involved in these types of activities every day. The Alliance also is a venue that allows those who have information or experience doing green landscaping to advocate and share that valuable knowledge with others. Together, we promote practices and products that still meet users needs but have.better environmental profiles than current methods. 11 ------- The GreenScapes Alliance reinforces these goals by emphasizing a holistic multimedia view of environmental impacts and steward- ship. In addition, the Alliance: • Provides information about the cost sav- ings that can be achieved from reducing material use and waste, resource conser- vation, and on the performance and dura- bility of environmentally preferable prod- ucts such as recycled-content and biobased products. • Educates land managers that green land- scaping efforts yield water and energy savings, conserves .landfill space, reduces - greenhouse gas emissions, and saves money. • Provides case studies, success stories, and technical assistance to help alleviate concerns regarding alternative practices and products. * Promotes market expansion and growth of environmentally preferable products. • Recognizes organizations that achieve environmental excellence in pollution pre- vention and resource conservation.
