Modeled Drainage & Watershed Analysis
See how terrain-favored drainage relates to a property at three useful scales: the parcel edge, the surrounding drainage landscape, and the larger watershed. This package is designed for early decision support when water movement may matter before acquisition, site planning, field review, or engineering work.
0 Mills Rd demonstration
Follow the drainage relationship from the parcel to the watershed.
In this demonstration, a terrain-derived drainage corridor approaches and adjoins the wooded southern/western edge of Parcel 14908. The analysis then follows that local relationship outward into the surrounding drainage network and Outlet Chicod Creek HUC-12.
What this package can help answer
Use the model to identify relationships worth verifying—not to substitute for engineering.
Where does terrain favor concentrated flow?
Identify modeled drainage pathways and where they approach, cross, or adjoin the parcel.
What happens beyond the property line?
See how off-site terrain and drainage connect the property to the surrounding landscape.
Where should follow-up focus?
Use the mapped relationships to target field checks, culvert/ditch review, survey, or engineering questions.
Important: Modeled drainage represents topographically favored flow paths at the selected terrain resolution and threshold. It does not establish a surveyed stream, ditch, culvert, legal drainage boundary, flood depth, stormwater capacity, wetland jurisdiction, permitting requirement, or engineering design condition.
Have a drainage question before you commit to the property?
Send the parcel or listing and describe the decision you are trying to make. GeoSite can determine whether a modeled drainage and watershed review is appropriate for the available data.
