Tulsa County requires grading and drainage review through its Subdivision Regulations and Building Code for any earth-moving exceeding roughly 50 cubic yards or altering natural drainage. Plans must show that runoff is not cast onto neighboring properties, consistent with Oklahoma common-law drainage rules.
Tulsa County regulates grading and drainage via the County Building Code (adopted IRC/IBC) and the Subdivision Regulations administered by the Tulsa County Engineer. Grading permits are generally required for excavation or fill over 50 cubic yards, for slopes steeper than 2:1, or for retaining walls over 4 feet tall (measured from footing to top). Oklahoma follows a modified civil-law rule of surface water drainage: landowners cannot unreasonably divert, accelerate, or concentrate runoff onto neighboring property (see Oklahoma cases such as Gregory v. Bogdanoff and 82 O.S. §1-2). Site plans must demonstrate positive drainage away from foundations and compliance with downstream conveyance capacity. Retaining walls over 4 feet require engineered drawings and separate permits. Compacted structural fill under slabs needs density testing. For subdivisions, the city of Tulsa's PFPI/SDCM is typically used as the technical standard.
Unpermitted grading: stop-work plus fines up to $500 per violation. Diverting drainage onto neighbors: civil liability plus county corrective order. Unpermitted retaining wall over 4 ft: permit required after the fact plus engineering review fees.
