TCC News Alert: Raleigh - New Stormwater Regulations for Smaller Sites

An amendment to the City of Raleigh’s Unified Development Ordinance (UDO) has gone into effect and will now incorporate stormwater regulation standards for smaller sites undergoing development or redevelopment that were previously exempt.

With this ordinance change, Development of previously exempt lots used for single family/duplex dwelling, single family/duplex subdivisions of less than one acre or less than half an acre used for
any other purpose that exceed new impervious area limits are required to provide an evaluation to determine how development will impact stormwater downstream. These sites are now subject to maximum impervious surface limitations based on zoning district.

The purpose of the new requirement is to ensure waterways remain healthy and that there is reduced flooding in areas during and following construction. City staff is dedicated to helping you navigate this change and the potential impact it will have on your development plans.

A copy of the ordinance can be found on the City of Raleigh website:
