Douglas W. Fischer, PE County Engineer Anoka County TRANSPORTATION DIVISION Highway City of Line Lakes 600 Town Center Parkway Line Lakes, MN 55014-1182 Re: Preliminary Plat-St. Clair Estates Dear Katie, March 14, 2016 We have reviewed the preliminary plat of St. Clair Estates, to be located north of CSAH 34 (Birch Street) and east of Hokah Drive NE within the City of Line Lakes and I offer the following comments: The existing right of way along this portion of CSAH 34 is 60 feet which should be adequate for future reconstruction purposes. Consequently, no additional right of way will be required at this time. No new access points onto CSAH 34 are proposed for this development, which is consistent with the previously completed corridor plan for this route, and all access is to be made via the internal connection to Hokah Drive NE. Also, it should be noted that Hokah Drive NE at CSAH 34 is to become a right turn in/right turn out access at some point in the future, as per the CSAH 34 corridor study. It should be anticipated that this development will increase turning maneuvers at the CSAH 34/Hokah Drive NE intersection, so the City may wish to weigh out those impacts and consider a timetable for the CSAH 34/Hokah Drive NE access changes in conjunction with this development. ACHD would like to work with local governments promoting compatibility between land use and the county highway system. It should be recognized that residential land uses located adjacent to county highways often results in complaints about traffic noise. Existing and/or future traffic noise from CSAH 34 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 Classification (NIAC) where establishment of the land use would result in violations of established noise standards. It is advised that the City and the Developer should assess the noise situation for this development as it is proposed to be located directly adjacent to CSAH 34, and take the level of action deemed necessary to minimize the impact of any highway noise by incorporating the appropriate noise mitigation elements into the design and phasing of this plat as applicable.
