Are there any special maintenance requirement for water quality basins with wetlands mitigation? Any advice would be appreciated.

    Thanks Chris. Are there any signs that it time to remove the vegetation or is it just a mater of storage volume and knowing when they were removed last.
    Thanks again!

    Hello – Thank you for your question.

    If wetland vegetation (e.g. cattails) exists within a water quality BMP, the vegetation may need to be thinned or removed once every 5-10 years (approx.). This prevents the vegetation from taking up stormwater storage volume and also permanently removes pollutants that the vegetation uptakes over time.

    Wetland vegetation removal within a BMP constructed solely for the intent of stormwater treatment SHOULD not require a 404 permit from the Army Corps of Engineers, however we advise everyone to check with the local Corps district first to ensure a permit is not required prior to maintenance of any BMP where wetlands exist.
