The fee for the permit shall be established from time to time by resolution of the City Council.

The environmental impact shall be considered in the granting of a permit, and conditions may be imposed by the City to minimize or mitigate the negative environmental impacts of the proposed work. The City Engineer shall determine when appropriate approvals and conditions have been met.

Full Breakdown
TMC § 7-4-103 bars grading, filling, excavating, or other land-disturbing activity without a City permit, unless the site is 10,000 square feet or less, disturbs 50 cubic yards or less, and meets several other small-scale thresholds. Permit applications under §§ 7-4-104 and 7-4-105 must include an interim erosion and sediment control plan, best-management practices to control runoff, erosion, and sediment while construction is underway, plus, where required, a final erosion and sediment control plan and a soils engineering report, along with a 10% cash bond or certificate of deposit and inspection fees set by Council resolution.
Violations & Fines
Grading without a required permit, or without an approved erosion and sediment control plan, is unlawful; the City Engineer can withhold approvals and require corrective work at the owner's expense.
