N.Y. Educ. Law § 7321
The practice of the profession of landscape architecture is defined as performing services in connection with the development of land areas where, and to the extent that the dominant purpose of such services is the preservation, enhancement or determination of proper land uses, natural land features, ground cover and planting, naturalistic and aesthetic values, the settings, approaches or environment for structures or other improvements, natural drainage and the consideration and determination of inherent problems of the land relating to the erosion, wear and tear, blight or other hazards. This practice shall include the location and arrangement of such tangible objects and features as are incidental and necessary to the purposes outlined herein but shall not include the design of structures or facilities with separate and self-contained purposes such as are ordinarily included in the practice of engineering or architecture; and shall not include the making of land surveys or final land plats for official approval or recording.
