Complete the Drainage Assistance Program Application online. Please allow 24-48 hours for us to respond.

Contact the Drainage Assistance Team at 919-996-3779 or StormwaterDrainage@raleighnc.gov if assistance is required. 

2. Prioritize Your ProjectIf you quality, we'll assess the severity of your project. Every project is scored and ranked with other drainage projects. Please note, we have about $1.75 million a year dedicated to this program.
3. Approve Your Project

We approve about 10 projects a year. The Stormwater Management Advisory Commission (SMAC) and Raleigh City Council review and approve these projects.

Project approval is not based on when a person submits their application. Funding for a project is based on its  prioritization score.

4. Design, Permitting, and Construction 
  • Design and permitting (about nine months to 1 year or longer if the project is complex)
  • Construction (about six months) - A project cannot move forward without a permanent drainage easement.
