Grading Mistakes Lead to Expensive Rework
Improper grading leads to drainage issues, failed inspections, foundation problems, and costly rework. These issues often appear after construction begins, when fixes are significantly more expensive. Diamond West Civil gets it right the first time.
What Scottsdale Requires Before the First Cut
Grading in Scottsdale is permitted work, and the paperwork sits on the critical path. Here is what has to be in place before a machine touches the ground.
A grading permit, almost always
Scottsdale builds on the 2021 International Building Code including Appendix J, and the city rewrote the exemption list down to four items: cemetery graves, refuse disposal sites, mining and quarrying regulated elsewhere, and exploratory excavation directed by a registered design professional. Nothing is exempt by cubic yards or by depth. If you are cutting or filling, budget the permit and the review time. See the city's preliminary grading permit page.
A grading and drainage plan with a seal on it
The Floodplain Administrator can require a drainage report and plan before any permit is issued, and the scope is set in the pre-application meeting. The report and plan have to be prepared by an engineer registered in Arizona and sealed, and the topographic survey behind them has to be certified by an Arizona civil engineer or registered land surveyor, from a field survey less than a year old and accurate to three inches. We build to that plan. We do not stamp it, and we say something early when what is drawn does not match how the site actually falls.
Stormwater cleared before you break ground
One acre of disturbance, or a smaller piece of a common plan that totals an acre, puts the job under the ADEQ construction general permit (AZG2025-001). The SWPPP is written first, the Notice of Intent goes through myDEQ, and the authorization to discharge has to be in hand. Scottsdale wants two copies of the approved Notice of Intent and SWPPP with the improvement plans, the SWPPP stays on site, and inspections run every seven days, or every fourteen days plus within twenty-four hours of a half inch of rain.
Dust control is a county permit
Dust is Maricopa County, not the city. Rule 310 requires a dust control permit once you disturb a tenth of an acre, about 4,356 square feet, holds visible dust under twenty percent opacity, adds trackout control at the exit at two acres or a hundred cubic yards hauled a day, and requires a certified Dust Control Coordinator on site at five acres. Review can take up to fourteen days, and the permit and approved plan have to be on the jobsite before work starts. Details on the county Rule 310 page.
Monsoon season runs June 15 to September 30. Disturbed ground has to stay stabilized through it, including nights and weekends, and ADEQ expects temporary stabilization within fourteen days of the last disturbance in an area where work has stopped. That is a scheduling problem as much as a compliance one, and it is worth pricing before June.

Almost certainly. Scottsdale adopted the 2021 International Building Code with Appendix J and amended the exemptions down to four cases: cemetery graves, refuse disposal sites, mining and quarrying regulated elsewhere, and exploratory excavation directed by a registered design professional. There is no exemption based on cubic yards or depth, so any cut or fill outside those four cases needs a permit.
