The City of Raleigh Stormwater Design Manual and associated UDO text changes became effective on Saturday, November 2, 2024. View the current manual and text changes below.
Raleigh Stormwater held two training events for home builders and designers.
Training for Home Builders
Stormwater Regulations Update for Home Builders covered new items related to developing residential lots under 1 acre. This will be most useful for small-scale home builders and for contractors doing large additions or accessory structures.
Stormwater Design Manual Training for Designers focused on changes to the stormwater requirements in site design, including stormwater conveyance, stormwater control measures, easement boundaries, and flood studies. The target audience was engineers, landscape architects, soil scientists, and surveyors.
