Landscaping involves modifying the visible features of an area of land through living elements like plants, natural elements like landforms, and abstract elements like weather. Landscaping is important for making yards beautiful and enhancing the environment. Objectives of landscaping include maintaining urban landscape character, preserving trees and grass, and enhancing public spaces. Open spaces are undeveloped land accessible to the public, such as parks, playgrounds, and vacant lots. They provide recreation and beautify neighborhoods. Guidelines for open spaces recommend they be adequately sized, accessible, well-designed, protected from wind, have amenities, access to sunlight, lighting, and be open and safe for public use.
