The purpose of this article is, in conjunction with the other requirements of this chapter, to promote and support the orderly, safe, attractive and healthful development of land located within the community, and to promote the general welfare of the community by preserving and enhancing ecological, environmental and aesthetic qualities, through established requirements for the installation and maintenance of landscaping elements and other means of site improvements in developed properties. Landscaping should be valued beyond the aesthetic because landscapes replace habitat lost to development and provide many other related benefits such as improvements to public health and quality of life, climate change mitigation, energy and materials conservation and increased property values. About half of urban water produced is used for landscape irrigation. Large water savings can be gained by efficient landscape design, installation, management, and maintenance. This is accomplished by choosing climate adapted plants, improving soil conditions, using, and maintaining high efficiency irrigation equipment and managing the irrigation schedule to fit the plants water needs as they are influenced by local climate. To increase water efficiency and better use a valuable resource, rainwater and stormwater collection and graywater and recycled water should replace or augment potable water use in landscapes. The following are additional factors considered in establishing the requirements of this article:
(1)
Paved surfaces, automobiles, buildings and other improvements produce increases in air temperatures, a problem especially noticeable in this southern region, whereas plants have the opposite effect through transpiration and the creation of shade. Likewise, impervious surfaces created by development generate greater water runoff causing problems from contamination, erosion and flooding. Preserving and improving the natural environment and maintaining a working ecological balance are of increasing concern. The fact that the use of landscape elements can contribute to the processes of air purification, oxygen regeneration, water absorption, water purification, and noise, glare and heat abatement as well as the preservation of the community's aesthetic qualities indicates that the use of landscape elements is of benefit to the health, welfare and general well-being of the community and, therefore, it is proper that the use of such elements be required.
(2)
The city experiences frequent droughts and periodic shortages of adequate water supply; therefore, it is the purpose of this article to require the use of drought resistant vegetation that does not consume large quantities of water. All installed plants and landscape material shall follow the City of Austin Grow Green Native and Adapted Landscape Plants guide as amended.
