Li Clt ��L �ZIC� <br /> Memo <br /> Profect Name; Buechler Estates Client. Centerville <br /> To: Planning and Zoning Commission File No: W- g8 806 <br /> From: Tom Peterson, Bonestroo Engineering Data: August 31 , 1998 <br /> Re: Prellminary plat - review comments <br /> Remarkar I have the following comments regarding this 5 -10t subdivision on Mound Trail, located in the <br /> extreme northwest corner of the city: <br /> 1. Lower the rim of MH -2 to 890.2. At elevation Shown, would stick out of ground 2 feet. <br /> 2. Change east invert elevation of 12" CMP for driveway to Lot -5 to 891.4. <br /> 3. Recommend sanitary sewer service be provided to the two properties west of the plat. Both have <br /> septic systems located directly adjacent to Centerville Lake. Both are in Lino Lakee, so an agreement <br /> would be needed between The two Cities and the residents, <br /> S. Silt fence needs to be extended along the edge of the lake to the existing sanitary manhole. <br /> 5. Label the 20-foot wide utility easement along the sanitary sewer, east of the plat. A 20 -foot easement <br /> should be provided for the entire length, not the 10 -foot shown. <br /> 6. Soils in this part of Centerville are known to be very poor for supporting structures. Soil borings are <br /> needed along Mound Trail (min 2 borings) and at each proposed house pad. Also, 2 borings should be <br /> provided along the sanitary sewer alignment. <br /> 7. The west plat line has a discrepancy in the field, and does not match what's shown on the plat drawing. <br /> This needs to be verified by the surveyor. <br /> 8. Drainage from the north half of the plat is being directed east to the east line of the plat. The water <br /> must be kept within the plat, and not allowed to drain on the adjacent property. Design contours need <br /> to be extended along the lot line, or a culvert installed. <br /> 9. The overhead electric line through the property has lines that hang quite low. May want to consider <br /> burying this utility for safety and setheti , reasons, <br /> 10. Contact Rice Creek Watershed for their comments on this plat <br /> tC: blurt Davich, F­ G.
