Response: We will add narrative to the final AUAR update to reflect the District's comments regarding inf3tratior�/filtra�ion/biofliration as per the comment. RCWD Comment 4: In addition to providing regional stormwater treatmentfacilities, the District would like to see this developmentplan incorporate and promote the use of the local stormwater management practices (e.g., inf''ilf�aiion practices, bioretention, low impact development techniques, etc.) that would also provide improved water quality and volume control at the individual site level. Response: Comment noted. Low impact development stormwater management techniques may be incorporated into the stormwater management approach for individual sites based on s�te-- specific considerations,which are not known at this time. RCWD Comment 5: It should be noted that the RCYYD is currently in the process of revising their stormwater rules and that these draft rules may be in effect by the time that this project is initiated. If the Twin Lakes Business Park is designed to meet existing District Rules, the District does not anticipate that the proposed rules will place further stormwater restrictions on the site. Response: Comment noted. �111c"ahz Goff, Minnesota Department of Transportation, September 24,2007: M��I�O�' Comment l: An updated Synchro S'imfT�a�c Analysis is strongly recommended lo determine the mitigation requirements for the improvements represented for the 1-35W/�'leveland Avenue northbound ramps and the I 35W/County Road D northbound ramps. Response: SRF` conducted updated Synehra/SimTraffic analyses as part of the overall areawide operations analysis and presented this information in a Technical Memorandum. All known Mn/DOT roadway improvements programmed at the time of our analysis were tal{en into account. If additional Mn/DOT roadway improvements have arisen, please advise. The detailed level of service operations analysis results were presented along with the recommended mitigation strategy necessary for each key intersection (or roadway segment) to operate acceptably. Additional clarification of this comment may be necessary. MnIDQ';�" Comment 2: 7�af�c noise fi^om I 35W could exceed noise standards established by the Minnesota Pollution Control Agency (MPCA), the U.S Department of Housing and Urban Development, and the U.S. Department of Transportation. Minnesota Rule 7030.0030 states that municipalities are responsible for taking all reasonable measures to prevent land use activities listed in the MPCA's Noise Area Classificatiort (NAC) where the establishment of the land use would result in violations of established noise standards. Mn/DOT policy regarding development adjacent to existing highways prohibits the expenditure of highway funds for noise mitigation measures in such areas.
