  31. 31. Activity Frequency Establishment (1-3yrs) Watering plants (seeded areas up to 8 weeks, plugs and container plants in drought) 1” per week as needed Weed control (flail mow, string-trim, selective/preemerg herbicides, mechanical removal , foliar herbicide) Monthly Remove litter and debris (trash, leaves, sand, mower discharge) Monthly Monitor & repair erosion (stabilize soil, replace plants, secure edging) Monthly Check for standing water (longer than design, any puddles, saturated soil) Monthly Add mulch (moisture & weed control with plugs/containers, 3” or less) Annually Inspect drainage area (parking lot sweeping, open dumpsters, etc) Annually Replace dead plants (use design species/size: overseed, install deep cell plugs, maintain density) Annually, as needed Installation and Maintenance of Stormwater Treatment BMPs Workshop, December 2011
  32. 32. Activity Frequency Establishment (3yrs+) Vegetation cleanup (string-trim, spot spray, prescribed burn, prune) Annually, spring or fall Evaluate plant composition (woody invasion, grass/flower ratio, “right plant right place”) Annually Sediment removal, erosion control (pretreatment structures: forebay, check dams, swale) Annually Address animal damage (beaver dams, muskrat burrows, deer rubs) Annually Verify structural component function (v-notch weir, check dams, outlet protection, area inlet, valve or gate lube, underdrain, inflows) Annually Installation and Maintenance of Stormwater Treatment BMPs Workshop, December 2011
  33. 33. Activity Frequency Native Vegetation Swale String trim vegetation to minimize disturbance Annually Inspect for erosion in flow lines and slopes Annually Bioretention cell Evaluate soils for nutrients, physical make-up Annually Fortify edging material/adjacent landscape beds Annually Typical maintenance activities are outlined to provide a basis for scheduling and planning work but should not be considered wholly comprehensive or definitive. Activities and frequencies will vary depending on site conditions and expectations related to adjacent land use. Some activities shown may continue through the establishment and maintenance phases. It’s important to use adaptive management based on the goals of the practice and to integrate evaluation and assessment into a long-term maintenance plan. •Installation and Maintenance of Stormwater Treatment BMPs Workshop, December 2011
