Please show the delineated drainage basins as called for per the Required Items Checklist. 2. Please address the following design issues associated with the proposed bioretention areas: a. The width of the bioretention cells appears to have been overestimated in the Bioretention Supplement Forms. The width of the bioretention area may only be counted as the width of the level treatment area, not the whole footprint of the cut slope. In your resubmittal, please be certain to provide an adequately wide bioretention area. b. The soil media and planting plan should be called out on the detail sheets for the bioretention areas. The slope of the underdrain pipes must be called out on the plan sheets. In addition, outlets for the underdrain systems must be shown on the plans. d. It is preferable to place the construction sequence on the plans where it can be easily seen by the contractor. The language in the construction sequence should be re-worded to clearly state that bioretention cells may not have stormwater directed to them until the site is completely stabilized. The temporary sediment basins must be retained until the entire site is stabilized. Please clarify in item 2 of the construction sequence that the bioretention area must be constructed a minimum of 50 feet away from the stream. The entire boundary of the BMP maintenance easement must be shown on the plans.
