Blaine, MN Landscaping Rules: Rainwater Harvesting (2026)

No Blaine city ordinance specifically prohibiting or permitting residential rain barrels or rainwater harvesting was found in the city's published materials. In practice, rainwater harvesting is encouraged across the Twin Cities metro as a stormwater best-management practice, and Minnesota does not restrict residential capture of rooftop rainwater for outdoor use. A key practical benefit in Blaine: the city's lawn sprinkling restrictions exempt hand watering of gardens and trees using a watering can or hose, so emptying a rain barrel by hand is not limited by the odd/even schedule or the 10 a.m.–6 p.m. summer window. Rain gardens — engineered depressions that capture and infiltrate runoff — are expressly included within the definition of a 'managed natural landscape' under Minn. Stat. 412.925, which Minnesota cities (including Blaine) must allow on privately owned land, subject to maintenance and no-noxious-weed conditions. Residents installing larger cisterns or making plumbing connections should confirm building/plumbing permit requirements with Blaine Building Inspections, and avoid placing rain gardens in drainage or utility easements. County-area programs periodically offer discounted rain barrels through the Recycling Association of Minnesota.
