BMP Fact Sheet Minimize Total Disturbed Area A key component of LID is to reduce the impacts during development activities such as site grading, removal of existing vegetation, and soil mantle disturbance. This can be achieved through developing a plan to contain disturbed areas. Minimizing disturbance to existing trees during residential construction Source: Insite Design Studio, Inc. Applications Stormwater Quantity Functions Residential Yes Volume High Commercial Yes Groundwater Recharge Key Design Features • Identify and avoid special value and environmentally sensitive areas (See Protect Sensitive Areas BMP) • Maximize undisturbed open space • Minimize disturbance lot-by-lot • Maximize soil restoration and restore soil permeability • Minimize and control construction traffic areas • Minimize and control construction stockpiling and storage areas Benefits • Reduced runoff volume • Reduced peak rates • High water quality benefits • Increased infiltration capacity • Provides healthy environment for vegetation Limitations • Difficult to achieve on small development sites LID Manual for Michigan – Chapter 6 Page 75 High Ultra Urban Limited Peak Rate High Industrial Yes Stormwater Quality Functions Retrofit Limited TSS High Highway/Road Limited TP High Recreational Yes NO3 Temperature High High Additional Considerations Cost Low Maintenance Low Winter Performance High
