Q 6 QUG 0 8 Z00 =,osz?" The Division of Water Quality (DWQ) received your application for a 401 Water Quality Certification for the subject project on May 23, 2006. On May 251h, a letter was issued to you requesting more information. Pending submittal of this information the project was placed on hold by DWQ. The following information/comments were requested by this office in order to complete the review: a) A detailed diagram (cross section, profile, etc.) for the proposed road crossings on Stream B. The design for the road crossings should include efforts to maintain the base flow in the stream channel. Sills inside the culvert(s) and construction of floodplain benches upstream and downstream of the culverts may be required to prevent over widening of the channel. Details for these measures should also be provided. b) Because more than 150 linear feet of perennial stream is proposed mitigation is required. A letter of acceptance from the Ecosystem Enhancement Program or a proposed stream restoration plan must be submitted prior to DWQ's issuance of the 401 Certification. c) It is noted that buffers are proposed adjacent to the on-site streams. Please provide the width of buffers proposed along all streams/creeks (i.e. 50-ft., 100-ft., etc.) throughout the project. d) Calculations for the impervious area do not appear to include the road network for the development or the commercial area (due to the lack of details, it must be assumed that this would be approximately 100% impervious). Also, the site plan does not indicate the location of the different development types (high density, low density). Please provide more detailed information. e) The location of the stormwater discharge points. There should be no direct discharge of stormwater to any stream.
