<br />Mr. D. Welsch <br />December 11, 2001 <br />Page 2 <br /> <br />In Item No. 16 of the EA W there is the discussion of erosion and sedimentation. Since <br />large rains can still cause a great deal of damage to the water resources downstream of this site, <br />erosion control should consist of elements or methods in addition to sediment fences. The <br />primary erosion control methods should rely on erosion control blankets, and mulch and seed <br />that are placed on exposed soils where no work is planned for more than two weeks. <br /> <br />Water quality and surface water runoff are addressed in Item No. 17. We note that the <br />proposed building site wj1l have more than the City of Roseville's requirement of 25% for green <br />space. Efforts should still be made to reduce the amount of stor.mwater that will runoff from the <br />site. These efforts may include reducing impervious surfaces, using rain gardens, llsing swales <br />to convey sronnwarer, using infiltration tcchniquc:;. cmd using a fro5t ripper to 1005(:11 compacted <br />soils before they are planted to pennanent vegetation. <br /> <br />Thank you for the opportunity to review this project and the EA W. The project does not <br />require preparation of an Environmental Impact Statement (EIS) base:d on natural resource <br />impacts or considerations.
