Coeur d'Alene, ID Environmental Rules: Erosion Control (2026)

Erosion control in the City of Coeur d'Alene sits inside Chapter 13.30, the Stormwater Management Ordinance. Section 13.30.040(C)(3) requires the design, testing, installation and maintenance of erosion, sediment and construction site waste controls to follow city approved best management practices. The plan must be submitted and approved before any site clearing, excavation, grading or other development activity, and it must show both temporary and permanent measures. The plan is a minimum: the city can add measures after unexpected storms, for repair of existing systems, or to replace nonfunctioning ones. The permit holder and property owner maintain the measures unless the plan names another responsible party.

Section 13.30.050 sets the on-the-ground standards. Erosion, sediment or pollutants from construction that reach public property, or private property the permit holder does not control, must be eliminated to the maximum extent practicable. Site owners and permit holders must minimize tracking of mud, dirt, sand, gravel, rock or debris onto the public right of way and pay for cleanup or reimburse the city, and public rights of way must be cleaned curb to curb on a weekly basis. Construction ramps must use material that will not erode and cannot block stormwater runoff. Debris, dirt, aggregate, excavated material and supplies stay off the public right of way unless the city permits them in writing.

A lot cannot sit vacant after the topsoil is disturbed or natural cover removed unless control measures keep material from migrating off site. Sediment from disturbed soils must be detained on site and either stabilized there or removed in an approved manner, and channels that concentrate stormwater need protection and energy dissipation. Temporary controls come out only after final site stabilization, and the trapped sediment and disturbed soil must be permanently stabilized within 21 days of removal.

Under § 13.30.080, sites must pass a city inspection after the temporary controls are installed and again after final grading or permanent drainage and erosion facilities are complete. The permit holder schedules these through the city building department at least 48 hours ahead, and no work proceeds until the inspection is approved.
