Drainage <br /> calculations need to be provided Tor the street runoff contribution to the Center Hills <br /> development, as well as calculations showing the sizing of the proposed pond on lots 2, <br /> 3, and 4, Block 2. <br /> A large Mn/DNR protected wetland is located through the center of the plat. If this <br /> wetland is landlocked, volume calculations should be completed to show the 100 -year <br /> high Nater level of the wetland. <br /> Permits will be required from the Rice Creek Watershed District and possibly the <br /> MniC for the wetland impacts shown on the grading plan. No mitigation site is shown <br /> c tl plan. <br /> PRELIMINARY PLAT <br /> • Perimeter drainage and utility easements should be shown for each lot. <br /> • Cirainage and utility easements should be shown around all wetland areas. <br /> • F 20 -foot drainage and utility easement should be shown along the proposed storm <br /> sewer between lots 3 and 4, block 2. <br /> • Cwriership des!gnati0n of Outlot A will be required In the developers agreement. <br /> • Fdditional right-of-way would be required for the temporary cul-de -sac as shown on <br /> the plat. The cul-de -sac boundaries extend beyond the proposed right -O- -way. <br /> GRADING PLAN <br /> Pond and wetland normal and high water levels should oe shown on the grading <br /> P.an. <br /> Proposed contours should be shown on the grading plan. The grading plan only <br /> shows existing contours. <br /> • ks indicated above, storm sewer and drainage calculations should be provided for <br /> the development. <br /> SUMMARY <br /> At this time, the developer of the project is requesting a change In the zoning of the <br /> propery. The proposed zoning designation is R5. The developer would also like to <br /> secure a building permit as soon as possible for construction of a home on lot 6, block 1. <br /> However, it is important tha � t h e <br /> r^( preliminary <br /> � ] p l at � is at atleast reviewed and dis- cussed prior <br /> 1` SPM+ V' FS IVO�t', DATAI�ROJ ',et14080j18P{01C'6ROBW*jMybCyl ' <br /> Company <br /> pan `/ <br /> CONSULTING ENGINEERS <br />
