BMP Fact Sheet Vegetated Filter Strip A vegetated filter strip is a permanent, maintained strip of vegetation designed to slow runoff velocities and filter out sediment and other pollutants from urban stormwater. Filter strips require the presence of sheet flow across the strip, which can be achieved through the use of level spreaders. Frequently, filter strips are designed where runoff is directed from a parking lot into a stone trench, a grass strip, and a longer naturally vegetative strip. Vegetated filter strip along roadway Source: Wayne County Department of Environment Applications Stormwater Quantity Functions Residential Yes Volume Low Commercial Yes Groundwater Recharge Variations • Turf grasses • Prairie grasses, shrubs, and groundcover vegetation, including trees • Indigenous woods and dense vegetation Key Design Features • Use with level spreaders to promote sheet flow across strips • Longitudinal slope from 1-6 percent • Maintain dense vegetation • See Appendix for recommended filter strip native vegetation Site Factors • Water table to bedrock depth – N/A • Soils – N/A for permeability • Slope – 2-5 percent preferred (1-10 percent if soils/vegetation allow) • Potential hotspots – Yes with special design considerations • Max. drainage area – 100 feet impervious or 150 feet pervious upgradient Benefits • Low cost • Good water quality performance • Aesthetic and habitat benefits Limitations • Generally should be coupled with other BMPs for comprehensive stormwater management LID Manual for Michigan – Chapter 7 Page 289 Low Ultra Urban Limited* Peak Rate Low Industrial Limited* Stormwater Quality Functions Retrofit Yes TSS Med/High Highway/Road Yes TP Med/High Recreational Yes NO3 Med/High Temperature Med/High Additional Considerations Cost Low Maintenance Low/Medium Varies dependent on type of vegetation Winter Performance High * According to site characteristics
