Summary

A floodplain project permit is required before any construction or development in a special flood hazard area in unincorporated Skagit County, per SCC 14.34.100. Even septic tanks, drain fields, and hazardous waste storage need one, though routine landscaping and normal utility repairs are exempt. Permits are processed under SCC Chapter 14.06.

These county ordinances apply to unincorporated areas of Skagit County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A floodplain project permit, processed per SCC Chapter 14.06, must be obtained prior to construction or development on any property within a special flood hazard area as established in SCC 14.34.050. The permit is required for all structures and development activities, as well as those activities listed in Subsection (1) of this Section that may or may not otherwise require a project permit.

Full Breakdown

050. The permit reaches beyond structures: septic tanks and drain fields, dumping or storage of hazardous waste, and utility or road maintenance work not otherwise exempted all trigger the requirement. A set of activities is carved out, including routine landscaping maintenance that does not involve grading or filling, removal of noxious weeds and hazard trees, normal maintenance of structures like re-roofing that does not require a building permit, normal utility and road maintenance that does not expand paved or gravel areas, and ordinary farming and diking or drainage system operation along the Skagit and Samish Rivers.

Applications must include a vicinity map, project description, and scaled site plan showing 10-, 50-, and 100-year flood elevations where available, the special flood hazard area boundary, and any compensatory storage area. 170. Permit fees are set by the Department's adopted fee schedule, though the Board of County Commissioners can waive fees by resolution for repair of damage from a declared disaster.

Violations & Fines

Because SCC Chapter 14.34 governs, a violation carries a civil penalty of up to $1,000 per day per violation under SCC 14.09.330(2)(c), higher than the general $100-per-day rate for most Title 14 chapters. The Director may also issue a stop work order under SCC 14.09.220, and a person found in a new violation within one year of resolving a prior one can face double the normal civil penalty under SCC 14.09.330(2)(d).
