What We Track

We track the maintenance of:

About 94 devices owned and operated by the City of Raleigh
More than 2,200 devices on private property to make sure they are working correctly

We keep up-to-date maps and inventory of stormwater devices, pipes, and drains. Staff also determines when the City or resident needs to update the stormwater system.

SCM Maintenance

Private owners or homeowner associations that are responsible for SCMs should have sufficient funds to pay for maintenance, repair, or replacement. Learn more about saving funds for SCM maintenance and our maintenance refund program.
