Full Breakdown

Meridian City Code § 11-3A-18 requires an adequate storm drainage system in every development, built in accord with the city's adopted standards, specifications, and ordinances, with design and construction following Best Management Practice as adopted by the city. The city's Public Works Department separately adopts supplemental specifications, drawings, and design standards for public infrastructure, including stormwater systems, under § 8-6-1, and the City Council can amend those design standards by resolution. This is a citywide land-use requirement enforced through development review, not a stormwater discharge permit program administered by the state or county.

Violations & Fines

No drainage-specific fine is set; violations default to the Chapter 1-2-1 general penalty: a misdemeanor or infraction fine under Idaho Code, with each day of noncompliance a separate offense.
