sanitary sewer utilities. Emergency access to properties is also a concern. While all of these concerns may be addressed at the time of development, the City would have no control over futura conditions. It is Staffs opinion that this parcel could be developed to City standards by sacrificing one lot. ~: DNR Wetland # 114-P is located on the property. The ordinary high water level (OHW) in indicated to be 858.1 feet. Any work which changes the course, current or cross section of this wetland will require a DNR Protected Waters Permit. This project should be reviewed by the Lower Rum River Water Management Organization (LRRWMO) for compliance with their standards. Streets: The plat has been designed with the extension of Kx~ton St. N.W. from Wood Pond Hills into Chestnut Ridge. The extension of Krypton St. into Chesmut Ridge exceeds the 600 foot maximum cul-de-sac length by approximately 400 feet, exclusive of the private driveway that then extends off the end of the cul-de-sac. Given that the subject property is surrounded on 3 sides by wetland, an over-extended cul-de-sac; appears to be the only reasonable way to provide public access to this peninsula of high groun& Grading and Drainage.'. The chief grading concern will be the protection of the surrounding wetland fi.om erosion and sedimentation resulting fi.om the development. Silt fence has been specified for selected areas. The LRRWMO will address the adequacy of the proposed erosion control. Drainage from the right-of-way is proposed to be concenn-ated for discharge at two points. One is the existing catch basin at the end of Krypton-:Srreet N.W. in Wood Pond Iqills. A second inlet is located between proposed Lots 8 and 9 which is proposed ro discharge into a new sectimentafion pond. Staff is recommending piping the discharge from et'tis second collection point to the existing catch basin and sedimentation pond. This will eliminate the need to enter onto private property at a second location to maintain th. is extra sertimentation basin. P.ark Dedication: The preliminary plat will be reviewed by the Park and Recreation Commission at their regular meeting in October. tt is anticipated that the park dedication will consist of a cash payment in the amount of $620.00 per lot. The Planning and Zoning Commission will be meeting at 7:30 p.m. on Tuesday, October 5, 1993, to consider your request for prelimina.o, plat approval of Chesmut Ridge. I suggest that you, or your representative, be present at the meeting to answer any questions that may arise. If you have any questions, please feel free to call at 427-..1410. Respectfully, CWIW OF RAMSEY Sylvia 1;rolik Zoning Administrator City En~-~ineer
