If you are installing a culvert in a Parish-maintained right-of-way, you must submit anĀ online request for a culvert installation (see form below) 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.

An online application does not approve work. A valid permit issued by the Department of Public Works must be in hand before starting 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 a 911 address permitted.


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