Stormwater Manual updates





Several pages have been created or updated since the most recent newsletter, and several sections of the manual are undergoing updates this fall.
  1. Pretreatment— Section was updated and includes general information for pretreatment settling devices, pretreatment screens, and pretreatment vegetated filter strips.
  2. Infiltration practices (includes infiltration basins, infiltration trenches, underground infiltration, and dry wells) — The design, construction, and operation and maintenance pages have been updated. New pages address types of infiltration, case studies, and information on collecting and interpreting soil borings.
  3. Stormwater and rainwater harvest and use/reuse — Section in development and scheduled to be completed this fall.
  4. Construction stormwater — Section reorganized and includes information on erosion prevention practices and sediment control practices. Each of these sections is undergoing development and should be completed this fall. We’ve also begun adding photo galleries for construction practices.
  5. Stormwater infiltration, contaminated soils, and groundwater — See two new pages: Contaminated sites and stormwater infiltration and Screening assessment for contamination at potential stormwater infiltration sites
  6. Pollinator-friendly BMPs — Find information on designing and implementing pollinator-friendly stormwater BMPs.
  7. Virtual tours — See links to Minnesota organizations with virtual tours or good maps of their stormwater BMPs.
