Spatial Tree Plans and Heritage Trees

As part of Charlotte’s Unified Development Ordinance (UDO), building permits may require that trees on a property be mapped.  Whether you are a surveyor, contractor or landowner, we can help create the “Spatial Tree Data” plan required for your permit.  

Many urban development projects require that a detailed map of trees be submitted with the permit application (UDO Article 20.18).   Depending on the type of development work being done, this plan may require all trees over a certain size be mapped with their species and condition noted.   Large trees over a certain size may require special protections during the development process.  The measurement of trees for the purpose of the plan is very specific and requires specialized tools and knowledge.  

In many cases it’s not effective for a surveyor to map a property’s trees.  We have a North Carolina licensed forester on staff and we specialize in mapping, tree species identification, tree measurement and tree positioning.

For an average residential lot a plan is relatively straightforward particularly if there are no Heritage Trees on the site (Diameter at breast height greater than or equal to 30 inches).

For more detailed plans with heritage trees, where mitigation or removals will take place, a site visit is required to estimate plan creation.

What’s involved in a typical plan:

  • Acquire spatial data for parcels, roads and right of ways from County GIS websites, satellite based or drone/UAS images.
  • Pre-inspection setup of data such as infrastructure, data collection tasks and digital maps for devices.
  • Data collection including tree positioning, species ID and diameter, tree marking and classification (heritage trees, health). 
  • Spatial tree data plan draft creation.
  • Revise draft as necessary. 
  • Submit final plan.


We can assist with complex spatial plans such as for multi-unit developments.   In some cases a plan requires ongoing monitoring and updating of tree and mitigation data to include analytical derivatives for tree canopy.    For such projects we offer the digital infrastructure for a living and breathing spatial plan which you ca update and which will meet development and permitting requirements.

Note, we don’t currently provide arborists services to evaluate tree health, recommend species for sites, treat trees, prune trees or cut them down.  However, we can work with an arborists as needed.
