Creative Landscaping Projects That Work in Poway

Sustainable landscaping is a modern type of gardening or landscaping that takes the environmental issue of sustainability into account. According to Loehrlein in 2009 this includes design, construction and management of residential and commercial gardens and incorporates organic lawn management and organic gardening techniques.^[1]

A sustainable garden is designed to be both attractive and in balance with the local climate and environment and it should require minimal resource inputs. Thus, the design must be “functional, cost-efficient, visually pleasing, environmentally friendly and maintainable".^[2] As part of sustainable development, it pays close attention to preserving limited resources, reducing waste, and preventing air, water and soil pollution. Compost, fertilization, integrated pest management, using the right plant in the right place, appropriate use of turf and xeriscaping (water-wise gardening) are all components of sustainable landscaping.

Sustainability can help urban commercial landscaping companies save money.^[3] In California, gardens often do not outweigh the cost of inputs like water and labor. However, using appropriately selected and properly sited plants may help to ensure that maintenance costs are lower because of reduced inputs.

• Long-lasting
• Reduced water usage and no surface runoff or puddles
• Minimal use of fertilizers and pesticides
• Use of green waste
• Conservation of energy and resources^[4]

Sustainability issues for landscaping include:

• Carbon sequestration
• Climate change
• Water conservation
• Energy usage

Non-sustainable practices include:

• Consumption of non-renewable resources
• Greenhouse gas emissions

Some of the solutions are:

• Reduction of stormwater run-off through the use of bio-swales, rain gardens and green roofs and walls.^[5][6][7]
• Reduction of water use in landscapes through design of water-wise garden techniques (sometimes known as xeriscaping)^{[8][9][10][11]}
• Bio-filtering of wastes through constructed wetlands^[12]
• Irrigation using water from showers and sinks, known as gray water^[13]
• Integrated Pest Management techniques for pest control
• Creating and enhancing wildlife habitat in urban environments^[14]
• Energy-efficient garden design in the form of proper placement and selection of shade trees and creation of wind breaks ^[15][16]
• Permeable paving materials to reduce stormwater run-off and allow rain water to infiltrate into the ground and replenish groundwater rather than run into surface water^[17][18]
• Use of sustainably harvested wood, composite wood products for decking and other garden uses, as well as use of plastic lumber^[19]
• Recycling of products, such as glass, rubber from tires and other materials to create landscape products such as paving stones, mulch and other materials^[20]
• Soil management techniques, including composting kitchen and yard wastes, to maintain and enhance healthy soil that supports a diversity of soil life
• Integration and adoption of renewable energy, including solar-powered lighting^[21]
• Development of lawn alternatives^[22] such as xeriscaping,^[23] floral lawns,^[24] and meadows.^[25]

One step to garden design is to do a "sustainability audit". This is similar to a landscape site analysis that is typically performed by landscape designers at the beginning of the design process. Factors such as lot size, house size, local covenants and budgets should be considered. The steps to design include a base plan, site inventory and analysis, construction documents, implementation and maintenance.^[2] Of great importance is considerations related to the growing conditions of the site. These include orientation to the sun, soil type, wind flow, slopes, shade and climate, the goal of reducing irrigation and use of toxic substances, and requires proper plant selection for the specific site.

Sustainable landscaping is not only important because it saves money, it also limits the human impact on the surrounding ecosystem. However, planting species not native to the landscape may introduce invasive plant species as well as new wildlife that was not in the ecosystem before. Altering the ecosystem is a major problem and meeting with an expert with experience with the wildlife and agriculture in the area will help avoid this.^[26]

Mulch may be used to reduce water loss due to evaporation, reduce weeds, minimize erosion, dust and mud problems. Mulch can also add nutrients to the soil when it decomposes. However, mulch is most often used for weed suppression. Overuse of mulch can result in harm to the selected plantings. Care must be taken in the source of the mulch, for instance, black walnut trees result in a toxic mulch product. Grasscycling turf areas (using mulching mowers that leave grass clippings on the lawn) will also decrease the amount of fertilizer needed, reduce landfill waste and reduce costs of disposal.^[27]

A common recommendation is to add 2-4 inches of mulch in flower beds and under trees away from the trunk. Mulch should be applied under trees to the dripline (extension of the branches) in lieu of flowers, hostas, turf or other plants that are often planted there. This practice of planting under trees is detrimental to tree roots, especially when such plants are irrigated to an excessive level that harms the tree. One must be careful not to apply mulch to the bark of the tree. It can result in smothering, mould and insect depredation.

The practice of xeriscaping or water-wise gardening suggests that placing plants with similar water demands together will save time and low-water or drought-tolerant plants would be a smart initial consideration.

A homeowner may consider consulting an accredited irrigation technician/auditor and obtain a water audit of current systems. Drip or sub-surface irrigation may be useful. Using evapotranspiration controllers, soil sensors and refined control panels will reduce water loss. Irrigation heads may need readjustment to avoid sprinkling on sidewalks or streets. Business owners may consider developing watering schedules based on historical or actual weather data and soil probes to monitor soil moisture prior to watering.^[2]

When deciding what kind of building materials to put on a site it is important to recycle as often as possible, such as for example by reusing old bricks.

It is also important to be careful about what materials you use, especially if you plan to grow food crops. Old telephone poles and railroad ties have usually been treated with a toxic substance called creosote that can leach into the soils.

Sustainably harvested lumber is available, in which ecological, economic and social factors are integrated into the management of trees used for lumber.^[28]

A landscape architect is a person who is educated in the field of landscape architecture. The practice of landscape architecture includes: site analysis, site inventory, site planning, land planning, planting design, grading, storm water management, sustainable design, construction specification, and ensuring that all plans meet the current building codes and local and federal ordinances.^[1]

The practice of landscape architecture dates to some of the earliest of human cultures and just as much as the practice of medicine has been inimical to the species and ubiquitous worldwide for several millennia. However, this article examines the modern profession and educational discipline of those practicing the design of landscape architecture.

In the 1700s, Humphry Repton described his occupation as "landscape gardener" on business cards he had prepared to represent him in work that now would be described as that of a landscape architect.

The title, "landscape architect", was first used by Frederick Law Olmsted, the designer of New York City's Central Park in Manhattan and numerous projects of large scale both public and private. He was the founder of a firm of landscape architects who employed highly skilled professionals to design and execute aspects of projects designed under his auspices.

Depending on the jurisdiction, landscape architects who pass state requirements to become registered, licensed, or certified may be entitled to use the postnominal letters corresponding to their seal, typically RLA (Registered Landscape Architect) or more recently, PLA (Professional Landscape Architect) n.^[2] In the US, all 50 states have adopted licensure.^[3] The American Society of Landscape Architects endorses the postnominal letters PLA, for Professional Landscape Architect, even though there is no legal or professional distinction between the use of RLA or PLA.^[4]

The Australian Institute of Landscape Architects (AILA) states that "Landscape Architects research, plan, design, and advise on the stewardship, conservation, and sustainability of development of the environment and spaces, both within and beyond the built environment".^[5] This definition of the profession of landscape architect is based on the International Standard Classification of Occupations, International Labour Office,^[6] Geneva.

Some notable Australian landscape architects include Catherin Bull,^[7][8] Kevin Taylor,^[9] Richard Weller, Peter Spooner,^[10] Sydney based writer and designer (Doris) Jocelyn Brown,^[11] Grace Fraser,^[12] Bruce Mackenzie,^[13][14] Mary Jeavons,^[15] Janet Conrad,^[16] Dr Jim Sinatra,^[17] William Guilfoyle, Ina Higgins, Edna Walling, and Ellis Stones.

To become a recognised professional landscape architect in Australia, the first requirement is to obtain a degree in landscape architecture accredited by the Australian Institute of Landscape Architects. After at least two years of recognised professional practice, graduates may submit for further assessment to obtain full professional recognition by AILA.

The Canadian Society of Landscape Architects (CSLA) is the country's professional association of landscape architects.^[18] Some notable Canadian landscape architects include Cornelia Oberlander,^[19] Claude Cormier,^[20] Peter Jacobs, Janet Rosenberg,^[21] Marc Ryan, and Michael Hough.^[22]

The Landscape Institute is the recognised body relating to the field of Landscape Architecture throughout the United Kingdom. To become a recognised landscape architect in the UK takes approximately seven years. To begin the process, one has to study an accredited course by the Landscape Institute to obtain a bachelor's degree in landscape architecture or a similar field. Following this one must progress onto a postgraduate diploma in the field of landscape architecture covering the subject in far greater detail such as mass urban planning, construction, and planting. Following this, the trainee must complete the Pathway to Chartership,^[23] a challenging program set out by the Landscape Institute. Following this, one is awarded a full landscape architect title and membership among the Chartered Members of the Landscape Institute (CMLI).

The United States is the founding country of the formal profession entitled landscape architecture. Those in this field work both to create an aesthetically pleasing setting and also to protect and preserve the environment in an area. In the U.S., a need to formalize the practice and a name for the profession was resolved in 1899 with the formation of the American Society of Landscape Architects. A few of the many talented and influential landscape architects who have been based in the United States are: Frederick Law Olmsted, Beatrix Farrand, Jens Jensen, Ian McHarg, Thomas Church, Arthur Shurtleff, Ellen Biddle Shipman John Nolen, Lawrence Halprin, Charles Edgar Dickinson, Iris Miller, and Robert Royston.

Royston summed up one American theme:

Landscape architecture practices the fine art of relating the structure of culture to the nature of landscape, to the end that people can use it, enjoy it, and preserve it.

The following is an outline of the typical scope of service for a landscape architect:^[24]
