— Typical Maintenance Activities — • trimming/replanting vegetation • removal of accumulated trash, debris, and sediment • unclogging pipes and outfalls • repairing/stabilizing erosion, cracks, settlements, rodent holes • repairing structural components • replacing underdrain or sand filter
Wa Ways to Help lp V Vegeta tatio tion S Stay Health lthy • Mowing – Cut no shorter than 6-8 inches – Grass on embankments should be cut at least twice during the spring and fall and once during the summer • Pest and Weed Control – Reduce the amount of pollutants reaching the facility by avoiding over fertilization and excess pesticide use • Removing Small Sediment Deposits – Bare areas should be vigorously raked, backfilled if needed, covered with top soil, seeded and mulched. • Unwanted Vegetation – Consistent moving and monitoring will control any unwanted vegetation – Be aware of invasive plant species such as Phragmited, purple loosestrife or autumn • “No Mow” Zone – 25 Foot vegetated buffer around the perimeter of wet ponds may be established to filter pollutants from adjacent properties and to help prevent shoreline erosion. The buffer should only be mowed once a year after mid-August. • Harmful Activities – Activities that have the potential to damage vegetation, or compact the soil should be avoided near the structure.
