Revision as of 23:54, 20 February 2014

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 shown below are approximate.

Updates to the bioretention section

(February-March, 2014). Work on this section has been on-going for several months. See What's New for recent updates to the Manual. Future updates include the following:

  • 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;
  • updated design specifications for bioretention and infiltration BMPs;
  • new information on construction methods, construction techniques, and maintenance of infiltration and bioretention BMPs; and
  • information on credits for water volume, phosphorus, and total suspended solids.

Creation of a section on trees (urban forestry)

(February-March, 2014). Work on this section (see Trees) has been on-going for the past few months. Several pages have already been added, but the following information will be added in the near future:

  • design specifications for tree quality and tree planting;
  • construction design specifications for tree stormwater BMPs;
  • guidelines for construction activities adjacent to existing trees;
  • maintenance guidelines for trees;
  • monitoring guidelines for tree BMPs; and
  • a fact sheet summarizing the applicability of urban forestry to stormwater management and use of trees as urban stormwater BMP;

Updates stormwater infiltration topics

(Spring/Summer 2014) A new section on stormwater infiltration will be added to the Manual and will include the following.

  • basic concepts related to the infiltration of stormwater
  • Best Management Practices that can be used for stormwater infiltration
  • select monitoring studies that investigated groundwater quality impacts associated with stormwater infiltration
  • a discussion of area-wide or regional groundwater quality or quantity impacts associated with stormwater infiltration
  • stormwater pretreatment considerations for protecting shallow groundwater quality
  • groundwater mounding considerations for infiltrated stormwater
  • groundwater separation distances for infiltrated stormwater
  • updates on stormwater infiltration constraints
  • considerations for stormwater infiltration in Wellhead Protection Areas
  • considerations and options for stormwater infiltration in areas with contaminated soils or contaminated groundwater
