The Project consists of 316 tax parcels on approximately 962 acres in the city of Lino Lakes, Anoka County, Minnesota. The study area is bounded by Pine Street NE to the north, Sunset Avenue (CSAH 53) to the west, Century Trail and Carl Street to the south, and 4th Avenue to the east. Main Street (CSAH 14) is an east -west road that bisects the study area. The surrounding area generally consists of private residences ranging from medium -density housing to farmsteads. The study area is currently used for residential and agricultural (sod) purposes. Regarding matters for which the Minnesota Pollution Control Agency (MPCA) has regulatory responsibility and other interests, the MPCA staff has the following comments for your consideration. Wastewater • A figure should be provided that shows the location of the major sewer system features in the project area that are described in the draft AUAR. Watershed • With this development, there will be an increase in impervious area. Design considerations should be taken to reduce salt usage which could lead to a chloride impairment for nearby resources. Planning to store snow in areas that won't increase icy areas as the pile melts and planting trees in strategic places will be beneficial. • The goal is to develop with winter maintenance in mind and use less salt. There is a ditch in the Southeast corner of the project area that has had high chloride samples collected. While not impaired, being proactive may help keep it off of the impaired waters list for chlorides. We appreciate the opportunity to review this Project. Please be aware that this letter does not constitute approval by the MPCA of any or all elements of the Project for the purpose of pending or future permit actions by the MPCA. Ultimately, it is the responsibility of the Project Proposer to secure any required permits and to comply with any requisite permit conditions. If you have any questions Page 564 of 617
