Culvert Permit

Culvert Requirements

If you are installing a culvert in a Parish-maintained right-of-way, you must submit an online request for a culvert installation to the Parish Permits Office. This ensures that culverts placed on Parish-maintained roads are the correct size to allow water to flow at a steady pace, reducing the possibility of flooding.

Culvert Installation Request

It should be noted that the online application is just that, an application only and does not approve work. A valid permit issued by the Department of Public Works must be in hand prior to start of any work in the Parish right-of-way.


The permit fee for a culvert installation and inspection is $10.00. If you recently purchased a 911 address permit, there is no charge for a culvert permit as it is included in an 911 address permit.


The culverts that can be placed in Parish-maintained right-of-ways are ones approved by the Caddo Parish Public Works Department. The Parish recommends concrete culverts, but you can also use a metal corrugated culvert. We do not recommend plastic culverts because of lack of durability.
