Box 9 Albertville, MN 55301 RE: Albertville Crossing Commercial/Retail Center, Multi-Family Townhomes and Single Family Residential Lots Environmental Assessment Worksheet (EA W) City of Albertville, Wright County Dear Ms. Goeb: The Minnesota Department of Natural Resources (DNR) has reviewed the EA W for Albertville Crossing consisting of a commercial/retail center, multi-family townhomes and single family residential lots in Wright County. We offer the following comments for your consideration. General Comments The project proposes a high density oftownhomes in a small area along the proposed Lachman and Lambert avenues. The proposed density creates a large amount of impervious surface, totally isolates the large wetland in Block 4 and will likely disturb or eliminate wildlife species that periodically require access to uplands for completing part of their annual or life cycle. Elimination of Lot 22 would preserve a large area of wetland. Also a reconfiguration of Lot 1 in conjunction with moving townhomes 2-5 to the west and slightly south (i.e. off the street front) would avoid impacts to the northeasterly wetland and eliminate having to mitigate its loss. This is significant because the Wetland Conservation Act (WCA) requires replacement of wetland functions and values, not just replacement of lost acreage. The EA W does not adequately quantify wetland impacts and impacts present are not fully mitigated. We are concerned that WCA sequencing requirements have not been met. Reconfiguring the proposed layout of the development and reducing density in order to maintain a buffer strip around the wetland would greatly minimize the loss of wetland functions and values. If revising the layout is not acceptable, then we recommend that project approval be conditioned on 1) the applicant assessing wetland functions and values to be lost, 2) the applicant mitigating lost functions and values through the WCA review process, and 3) mitigation at greater than a 2:1 ratio to fully replace lost functions and values. This should occur in conjunction with the WCA Technical Evaluation Panel and Minnesota DNR's Regional Environmental Assessment Ecologist (Michael R. North, 218-828-2433).

Printed on Recycled Paper Containing a .., Minimum of 10% Post-Gonsumer Waste Albertville Crossing March 8, 1999 Page 2 Section 10 - Cover Types The before and after wetland cover type values are inconsistent with other EA W information. The "after" total for wetlands reflects 2:1 mitigation for 3.4 acres of impacts, but 2.8 acres of this mitigation are proposed to occur off-site (Section 12). Therefore, the "after" total for the wetlands on-site would be 13.0 acres. From the figures listed in Section 10 and 12, it is unclear if wetland mitigation will be off-site or on-site. We recommend as much mitigation occur on-site as possible. Section 11 a - Fish, Wildlife, and Ecologically Sensitive Resource We disagree with the statement that since no lakes are on site, there will be no impacts to fish. DNR Fisheries staff inspected the site and noted there is a small intermittent stream with a narrow band of riparian reed canary grass. Values of intermittent streams to fisheries potentially include: 1) being a source of invertebrates, detritus, and forage fishes (e.g., fathead minnows, brook sticklebacks) that form the basis of the food chain for larger game fish, and 2) spawning sites for northern pike. They can also be a conduit for transporting pollution downstream to valuable aquatic habitats. Our Fisheries staff recommend that Best Management Practices for runoff and erosion control be utilized during construction, and that silt barriers and erosion control devices be maintained throughout the construction phase of the project. Section 12 - Physical impacts on Water Resources DNR fisheries staff concurred that the proposal to treat stormwater on-site before it is discharged to wetlands for polishing is desirable. We recommend that stormwater ponds be irregularly shaped and designed to function in conjunction with the remaining wetland areas. Thank you for the opportunity to review this project. We look forward to receiving your record of decision and response to comments. Minnesota Rules part 4410.1700, subparts 4 & 5, require you to send us your Record of Decision within five days of deciding this action.
