What this is
A map of storm sewer headwalls (the concrete structures where storm drains meet pipes) across Oklahoma City.
Why it matters to you
Headwalls prevent erosion where stormwater enters pipes. If one fails near your property, it could cause flooding or sinkholes. This data helps:
- Neighbors report clogged or damaged headwalls after heavy rain
- Developers check drainage infrastructure before building
- Homebuyers assess flood risks near a property
How to read this data

- Sub Type: What kind of headwall (e.g., “concrete box”, “pipe end”)
- Location: Written description like “SW corner of 12th St & Western Ave”
- Project Number: Links to construction records if repairs were done
