In engaging in the practice of landscape architecture, a licensee shall act with reasonable care and competence, and shall apply the technical knowledge and skill that are ordinarily applied by licensed landscape architects of good standing practicing in the same locality.
In designing a project, a licensee shall take into account all applicable federal, state, and municipal building laws and regulations. While a licensee may rely on the advice of other professionals (e.g., attorneys, engineers, and other qualified persons) as to the intent and meaning of such regulations, once having obtained such advice, a licensed landscape architect shall not knowingly design a project in violation of such laws and regulations.
A licensed landscape architect shall undertake to perform professional services only when he or she, together with those whom the licensee may engage as consultants, is qualified by education, training, and experience in the specific technical areas involved.
A licensed landscape architect shall not accept compensation for his or her services from more than one party on a project unless the circumstances are fully disclosed in writing and agreed to by all interested parties.
A licensee shall fully disclose in writing to his or her client or employer any business association or direct or indirect financial interest which is substantial enough to influence his or her judgment in connection with the performance of professional services.
When making public statements concerning the practice of landscape architecture, a licensee shall disclose when he or she is being compensated for making such statements.
If in the course of his or her work on a project, a licensed landscape architect becomes aware of a decision made by his or her employer or client, against such licensee's advice, which will result in a violation of any applicable federal, state, or municipal building laws or regulations, and which will, in the licensee's judgment, materially and adversely affect the safety to the public of the finished project, the licensed landscape architect shall:
A licensed landscape architect shall not willfully make a materially false statement or willfully fail to disclose a material fact requested in connection with his or her application for a license or renewal or reinstatement of a license.
A licensed landscape architect shall not assist in the application for licensure of an individual known by the licensed landscape architect to be unqualified with respect to education, training, experience, or character.
A licensed landscape architect shall not sign or seal technical submissions unless they were prepared by the licensee or under his or her responsible charge; provided, however, that a licensee may sign and seal those portions of any
technical submissions that were prepared under the responsible charge of another licensed landscape architect if he or she has reviewed such portions and has coordinated their preparation.
A licensed landscape architect shall not, in the conduct of his or her practice, knowingly violate any municipal, state, or federal criminal law.
A licensed landscape architect shall neither offer nor make any payment or gift to a government official (whether elected or appointed) with the intent to influence the official's judgment in connection with a prospective or existing project in which the licensee is interested.
A licensee possessing knowledge of a violation of the provisions set forth in §§ 1909.1 through 1909.12 by another licensed landscape architect shall report such knowledge to the Board.
