We will be populating this site with information on future updates to the Manual. We anticipate having this page up-to-date by mid-August. Timelines are approximate.

  1. Updates to the bioretention section (August-October, 2013). Updates include the following:
  • definitions, examples and graphics that differentiate filtration, bioretention and infiltration BMPs and different types of filtration, bioretention and infiltration BMPs;
  • guidance and recommendations for determining soil infiltration rates within infiltration and bioretention BMPs;
  • refinement of existing stormwater pretreatment requirements or guidelines for each bioretention and infiltration BMP type;
  • guidance and recommendations on the use of soil ripping to increase infiltration capacity of infiltration and bioretention BMPs;
  • guidance and recommendations on the use of soil amendments to improve the infiltration and pollutant removal function of infiltration and bioretention BMPs;
  • updated design specifications for bioretention and infiltration BMPs; and
  • new information on construction methods, construction techniques, and maintenance of infiltration and bioretention BMPs;
  • information on credits for water volume, phosphorus, and total suspended solids.
