Full Breakdown
Flint's site plan review ordinance, § 50-8.3, requires Planning Commission review and approval before a building permit issues for most new construction. Item (36) of the required plan contents calls for a "basic indication of existing and proposed drainage patterns and structures, including location and nature of any streams, drains, wetlands, unstable soils or fences designed to prevent soil erosion and a general description of method and location of storm water detention." Small projects are exempt: single-family developments under three units, interior alterations, and additions under 1,500 square feet or 20% of the building's size don't need a site plan at all.
Violations & Fines
Starting site-plan-triggered construction without Planning Commission approval, or submitting a plan missing the required drainage and erosion information under § 50-8.3(d)(36), blocks issuance of the building permit.
