R.I. Gen. Laws § 45-23.1-1
The city or town council of any city or town having a plan commission established pursuant to chapters 22 and 23 of this title or pursuant to any special act applicable to certain cities or towns, is authorized and empowered to establish an official map of the city or town identifying and showing the location of the streets of the city or town existing and established by law as public streets and the exterior lines of other streets deemed necessary by the city or town council for sound physical development. A public hearing in relation to the map shall precede the adoption, at which parties in interest and citizens shall have an opportunity to be heard. At least ten (10) days' notice of a public hearing shall be published in a newspaper of general circulation in the city or town. Before adoption of the ordinance, the city or town council shall refer the matter to the plan commission for a report on the map, but if the plan commission does not make its report within forty-five (45) days of the reference, the necessity for the report may be deemed to be waived. The city or town council shall certify the fact of the establishment of an official map to the city or town recorder.
