5EFJ <br />August 1, 1995 <br />Ms. Mary Kay Wyland <br />City of Lino Lakes <br />1189 Main Street <br />Lino Lakes, MN 55014-2123 <br />Dear Ms. Wyland: <br />3535 VADNAIS CENTER DRIVE, 200 SEH CENTER, ST PAUL, MN 55110 612 490-2000 800 325-2055 <br />ARCHITECTURE • ENGINEERING • ENVIRONMENTAL • TRANSPORTATION <br />RE: Lino Lakes, Minnesota <br />Pine Ridge 2nd and 3rd <br />Swale Change <br />SEH No. A-LINOL3336.00 <br />We have reviewed the grading plan prepared by Matke Engineering dated 6/14/96 (should be <br />6/14/95). This grading plan proposes changes to the south lot line swale in Pine Ridge 2nd and 3rd <br />to allow for the construction of lookout style homes instead of full basement ramblers. Although <br />the proposed grading changes lessen the slope of the swale, we do not anticipate any problems as <br />there is draintile in the swale. <br />The excavated material is proposed to be stockpiled south of Pine Ridge 2nd and 3rd. The plan <br />shows this pile to be approximately 4 to 6 feet high with 3 to 1 side slopes. Approximate volume <br />is stated as 7,000 cubic yards. This material is proposed for use on a future development on this <br />site. We have no objections to stockpiling this material, but do have the following <br />recommendations: <br />1. Side slopes shall not be steeper than a 3:1 slope. <br />2. Height of the stockpile shall not exceed 6 feet. <br />3. Side slopes shall be seeded and mulched to prevent erosion. <br />4. Stockpile shall be monitored by owner and kept free of weeds. <br />Please contact me if you have any questions. <br />Sincerely, <br />i;r0X..f-Nt <br />Steven F.
