Mr. Steve Ach • July 17, 1996 Page Three • Several of the proposed driveways appear to be steep and several appear to be flat. It is difficult to determine if these are excessively steep or flat at this scale drawing. The ones that appear to be steep are Lots 18, 21, and 23, while the ones that appear to be flat are Lots 2, 4, 6, and 17. Lot 5 has the home elevation below the street grade. • It is not clear what the proposed elevations of the houses on Lots 9 and 13 are. These should be provided. • There are a couple of locations, such as between Lots 9 and 10 and between Lots 11 and 12, where drainage does not follow lot lines. It would be advisable to keep drainage along the lot lines if possible. If this is not possible, additional easements will need to be provided across these lots. • It is not clear where drainage from the NURP pond located in Lot 24 flows to. • There is limited erosion protection, such as silt fence, shown on the Preliminary Grading Plan. More may need to be provided. This can be reviewed in greater detail when a larger scale grading plan is provided. • The typical lot shown in the legend includes sanitary sewer and watermain. • This plat is located in the rural area of the City where no City utilities are to be provided. This correction should be made on the typical layout shown. • The typical street section is adequate in width and appears to be adequate in strength. The strength of the section will need to be verified with soil borings or visually inspected and concurred by a soil specialist during the construction of the roadway. • The low points should be provided with emergency overflows for the catch basin and storm sewer, such that if they are plugged or cannot handle the amount of water in a particular rain event, the runoff will find its way to the NURP pond and into the overall drainage system without endangering any of the homes. This is another item that is hard to review with the drawing at such a small scale. C. MISCELLANEOUS • Glenn Sundeen from the Elk River Municipal Utilities has recommended a minimum of four street lights in the development, one located at Fillmore Street, one located at the extreme north end, and a minimum of two located on either side of the high point to provide lighting for safety considerations. Glenn did point out that this area is outside of the Elk 41, River Municipal Utilities service area; therefore, the Developer will need to contact Anoka Electric Co-op concerning the street light installation. 230/312-1509.jul
