LandTech was recently contacted by a property owner in Knox County, Tennessee about providing a design for a pipe culvert in his side yard. Approximately 25% of the property is isolated by a stormwater ditch crossing the parcel. The property owner wants to install a pipe culvert crossing for easy access across the swale to the isolated portion of the property.
Sometimes a seemingly simple project involves numerous regulatory issues.
When we visited the site, we noticed a small amount of water flowing in the ditch. This would mean the ditch is technically a “stream”. Construction in a stream requires an Aquatic Resource Alteration Permit, or ARAP, from the Tennessee Department of Environment & Conservation (TDEC). More information about ARAP’s can be found here:

We also discovered this portion of the property is in a FEMA 100-year special flood hazard area. This means the culvert would need to be sized to pass a 100-year flood without impacting the water surface elevation. If you’re interesting in finding the limits of any 100-year special flood hazard area, visit the FEMA Flood Map Service Center website:
Needless to say, this project is more complicated than the property owner anticipated, but LandTech can ease your burden by providing the advice and professional land surveying and civil engineering services needed to navigate the complexities of a project like this.
