(2) Secure for each resident of the District of Columbia with intellectual or developmental disabilities, regardless of ability to pay, such habilitation as will be suited to the needs of the person, and to assure that such habilitation is skillfully and humanely provided with full respect for the person’s dignity and personal integrity and in a setting least restrictive of personal liberty;

(b) To accomplish these purposes, the Council of the District of Columbia finds and declares that the design and delivery of care and habilitation services for persons with intellectual or developmental disabilities shall be directed by the principles of normalization, and therefore:
