Functional maintenance may include dredging, vegetation removal, bank stabilization, and maintenance or repair of drainage structures. design storm inflow to the pond. depth of eighteen inches below the normal pool water surface elevation. Maintenance access shall
Ponds can help to store water for later use. Maintenance is essential to the proper functioning of STPs. Retention ponds should be paired with upstream sustainable drainage components such as smaller detention basins and swales that give primary treatment and sediment management.
