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.
North Richland Hills FAQ
My neighbor's new patio is flooding my yard in NRH. What can I do?
File a complaint with NRH Code Compliance at (817) 427-6650. The city can enforce drainage easement rules and positive drainage requirements, though pure cost disputes are civil matters between neighbors.
Do I need a permit to regrade my backyard?
Minor regrading (less than 50 cubic yards, outside easements, no change to drainage patterns affecting neighbors) typically does not need a permit. Larger projects or work near easements requires a grading permit.
