In some cases, the certain elements of a Minimum Standard would not be applicable to the single-family residential project or the requirement would be an undue burden compared to the scale and impact of the project. In an effort to reduce the burden of the new regulations on single-family homeowners and encourage land use practices that meet RIDEM's stormwater treatment goals.

Accordingly, both DEM and CRMC have developed Rhode Island Stormwater Management Guidance for Individual Single-Family Residential Lot Development. All applicants may also elect to fully comply with all minimum standards and performance criteria outlined in the RISDISM if they wish, or utilize the RISDISM for further guidance.
