MAR - 1 7 - 9 3 WED : 1 1 M A I E R STEWART' 2 ASSOC . P _ OE <br /> • <br /> Mr. Steve Rohlf <br /> March 16, 1993 <br /> Page Three <br /> 2. The proposed drainage system appears adequate; however, storm drainage <br /> calculations will be required to determine pipe sizing. <br /> 3. The ditch flowing under the proposed road at the southeast corner of the plat <br /> needs to be analyzed to determine the proper culvert sizing in order to provide <br /> for potential drainage from east of Meadowvale Road. <br /> E. Streets <br /> 1. No typical street section was provided. The City standard requires a section 32 <br /> feet wide from face of curb to face of curb. Surmountable curb and gutter is <br /> acceptable. The typical street section has consisted of five inches of aggregate <br /> 1111 base and two lifts of bituminous surfacing totalling 3 to 3-1/2 inches. However, <br /> soil borings will be necessary to determine the specific street section in this <br /> project. <br /> 2. The cul-de-sac at the north end of the project greatly exceeds the City's maximum <br /> length. In the future, when streets are extended to the north providing a second <br /> access, the cul-de-sac length will be within the maximum allowed by ordinance. <br /> 3. Sherburne County will require the dedication of an additional 17 feet of right-of- <br /> way along Meadowvale Road. <br /> 4. It is not clear whether or not the street right-of-way at the southeast corner of the <br /> preliminary plat actually abuts the Meadowvale Road right-of-way. If not, <br /> additional right-of-way acquisition will be necessary in this area. <br /> If you have any questions regarding any of these comments, please call. <br /> Sincerely, <br /> MAIER STEWART & ASSOCIATES, INC. <br /> Terry J. Maurer, P.E. <br /> TJM:tp <br />
