Box 490 <br />Elk River, MN 55330 <br /> <br />RE: OAKWOOD HILLS PRELIMINARY PLAT <br /> <br />Dear Mr. Ach: <br /> <br />As requested, we have reviewed the Preliminary Plat for the Oakwood Hills development. <br />Based on our review, comments received at the staff review meeting, and a number of <br />meetings with the Developer and his engineer, we would offer the following comments: <br /> <br />1. The Preliminary Plat that we reviewed was prepared by Passe Engineering, Inc., and <br /> was dated November 27, 1996. <br /> <br />This plat receives access from the northwest corner through the Hobbit Hills <br />Addition. The Developer will be required to upgrade Pascal Street NW from 200th <br />Avenue NW to the northwest corner of his plat. The Developer should also be <br />required to provide documentation that the Pascal Street easement over this stretch <br />of road does exist and is in favor of the City. <br /> <br />The current intersection at the northwest corner of the plat is not perpendicular, but <br />skewed slightly. Pascal Street should be extended further to the south in order to <br />make this intersection perpendicular. This will likely require the Developer to <br />acquire additional easement from the property to the west. <br /> <br />The wetlands have all been delineated and are shown on the Preliminary Plat. It <br />appears that the only wetland that is over one acre in size falls within Lot 1. This <br />lot needs to be large enough that, after subtracting the wetland area, it still meets the <br />minimum lot size of 2~h acres. It appears the only wetland mitigation required will <br />be near the northwest comer of the plat for the road construction. A mitigation plan <br />will need to be prepared and approved. <br /> <br />o <br /> <br />It is very difficult to read the contours of the Grading Plan at this scale. We would <br />suggest that the Developer be required to submit the Grading Plan at a 50 scale so <br />that the proposed versus existing contours can be easily read. <br /> <br />6. It appears that legs of County Ditch 28 run through this site. These should be <br /> identified and shown on the Preliminary Plat, as well as protected with drainage and <br /> <br />230/349-1413.feb An Equal Opportunity Employer <br /> <br /> <br />
