To: Ms. Mary Kueffner, Lake Elmo City Hall From: Wyn John, Lake Elmo Mayor Date: April 22, 1993 Subject: Response to EAW on CSAH 10 General: I consider the EAW pays inadequate attention to the design details in response to the environmental challenges and remedies. It provides little attention to alternative solutions in an environmentally sensitive area. Reports are referenced, but copies should have been provided to the various cities affected by the development. These are incremental costs in relation to the administrative costs of preparation of an EIS. More work or additional information is needed to ensure that an EIS is not required. Specific Comments: Project Title: Scope of the project was originally from I-694 to 1/4 mile east of CSAH 13. There is no reason given for the additional transition requirement east of CSAH 13. Page 2, para. 6, Description, line 9. Turn lanes for future street intersections should only be provided where environmentally feasible. Page 3, Description, line 13. Construction is understood to end 1/4 Mile east of CSAH 13. Page 3, Description. There is no discussion of alternatives considered to mitigate or avoid the wetland impact - e.g. alternative routes, bridges across wet land areas, together with relative costs. Page 7, line 4. "Wet Land Impact Analysis and Design." This report should have been more readly available for inspection by having a copy distributed to the local City Halls. Without seeing this report, a proper assessment of the wetland impact and compensatory design cannot be completed. Page 9, line 17. "The excavated basin will be lined with hydric soils excavated from the project area." There is no indication of an attempt to lay an impervious clay layer of specified depth to ensure that the new wetland, when created, will retain moisture. Alternatively, if an aquifer is penetrated by
