Old Design Manuals

There are two manuals in effect in the City of Raleigh through November 1, 2024:

1. Stormwater Design Manual (2002)
2. Guidelines for Land Disturbing Activity (2013)

These manuals will remain in effect through November 1, 2024, with the following exceptions:

• The above manuals do not contain information and guidance regarding the new Neuse Nutrient Rules, which become effective on May 1, 2023.
• The new Neuse Rules also require use of the State’s Minimum Design Criteria (MDCs) for stormwater control measure design. Therefore, the NCDEQ Stormwater Design Manual replaces Chapter 3.2 of the City’s 2002 Stormwater Design Manual.
