Watershed Management provides new development plan review and permitting for erosion and sedimentation control (land disturbances), stormwater and floodplain management for individual residential lots, subdivisions and commercial projects. Watershed Management also reviews flood studies for roadways, driveways and other encroachments crossing through floodplains and flood prone soil areas. 


Wake County administers the erosion and sedimentation control ordinances of the following municipalities:

Garner, Knightdale, Morrisville, Wendell, Rolesville & Zebulon.


Wake County administers the stormwater ordinances of the following municipalities:

Online Permitting Now Active – including single-lot erosion control permits!

All permit submittals will be made online through the Permit Portal.
You will submit the same application, fees, construction drawing, calculations and maps as always but DIGITALLY and through the PERMIT PORTAL. You will upload documents and be invoiced once the application and fees due are verified. You will be able to track the progress of your permit through the portal.
First, you will need to create a Login account. Engineering firms should consider creating an account for the firm rather than individuals.

Existing Permits:
If your permit was submitted prior to the Permit Portal, it was migrated to the new software system. We may need to update the permit file so that it is consistent with the new system. Once you register for the Portal, contact us so that we can link your old permits to your account. Then you should be able to see your old permits and add attachments as needed and be invoiced for resubmissions, renewals, etc. To add new attachments, use the "Pending Attachments" option and email your plan reviewer to notify them of the submittal. YOU WILL NEED TO BE A CONTACT ON THE CASE TO VIEW IT!

Stormwater Management Program

Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality in a watershed if the runoff is discharged untreated.

Erosion & Sedimentation Control

Wake County operates an erosion prevention program that aims to prevent sediment from leaving construction sites and contaminating streams, lakes, and river within Wake County's watersheds. We accomplish this by enforcing state and local erosion prevention regulations and by working with developers, builders and landowners in Wake County.

Floodplain Management

This program seeks to promote public health, safety and general welfare and to minimize public and private losses due to flood conditions within flood prone areas by implementing ordinance provisions designed to:

  • Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards or that result in damaging increases in erosion, flood heights or velocities
  • Require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction
  • Control the alteration of natural floodplains, stream channels and natural protective barriers, which are involved in the accommodation of floodwaters
  • Control filling, grading, dredging and all other development that may increase erosion or flood damage
  • Prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or that may increase flood hazards to other lands.
