Summary
Oakland requires a grading permit from the City Engineer or Building Official before any excavation or fill exceeding fifty cubic yards on a slope over 20%, any work totaling more than five hundred cubic yards, or land disturbance over an acre, under Chapter 18B of the Building Code amendments. Applications need an engineer-prepared drainage plan, and a separate section bars discharging concentrated storm water onto a neighboring property without an approved method.
No person shall do or cause any grading in private or public property without first having obtained a permit to do so from the City Engineer or Building Official whenever such grading will result in any of the following: ... The volume of excavation and fill combined will exceed five hundred (500) cubic yards on a parcel or contiguous parcels. ... Section 1815B.1 General. Except as established in this Section, it shall be unlawful for anyone to discharge or channel concentrated flow of storm water onto neighboring property.

Full Breakdown
2075, added by Ord. No. 5:1 (excavation); work within fifteen feet of a property line that breaches a 2:1 line from the boundary; grading near a building, pool, or retaining wall exceeding five feet of unretained slope; any grading in a designated Land Stability Problem Area regardless of volume; land disturbance on slopes over 20%; combined excavation and fill over 500 cubic yards; and grading, clearing, grubbing or land disturbance covering an acre or more. 2 exempts temporary street excavations already permitted under Title 12, excavations fully retained by a permitted structure on slopes of 10% or less, supervised test borings, individual cemetery plots, water wells, and gardening or agriculture.
3 needs a vicinity/site/grading plan, an erosion and sedimentation control plan, statements from the civil engineer in responsible charge, a soils report, a work schedule, a Master Fee Schedule deposit, a cost estimate, and proposed dust control measures. 6(4)) must coordinate temporary and final drainage facilities with the erosion controls and include hydrology/hydraulic calculations when required. 1 makes it unlawful to discharge or channel concentrated storm water onto neighboring property except through City-approved methods, draining to an improved street, an on-site dissipater at least fifteen feet from the property line, pumping to an approved disposal point, or a discretionary connection permit to the public storm sewer from the City Engineer. Every grading permit also requires a performance security equal to 100% of the engineer's estimated cost of work.
Violations & Fines
Section 1813B subjects any violation of Chapter 18B, including grading without a required permit or an unapproved storm water discharge under Section 1815B, to City abatement, with costs, fees, penalties, and accruing interest collected under Municipal Code Chapters 1.08, 1.12, and 15.08. The Building Official can also suspend or revoke a grading permit for noncompliance, and if a permittee fails to timely abate a hazard, the posted performance security is applied through Summary Abatement.
