Grapevine FAQ
Can my neighbor regrade their yard so water runs onto mine?
No. A landowner cannot collect and discharge concentrated stormwater onto an adjacent property without an easement. File a complaint with Grapevine Public Works or Code Enforcement.
Do I need a grading plan for a pool?
Yes, pool permits require a site plan showing grading and drainage, including how the spoil from excavation will be handled and how drainage patterns will be preserved.
Keller FAQ
Do I need a permit to regrade my Keller backyard?
Minor landscaping grade changes usually do not require a permit. Significant cut or fill, retaining walls, or changes to drainage easements require a grading plan reviewed by Development Services.
My neighbor raised their yard and now mine floods. What are my rights?
Texas follows modified common-law drainage rules. If a neighbor altered grade in a way that damages your property, you may have a civil claim. The city may also cite the neighbor if a platted easement is blocked.
