MN SS323 <br />174S Fox Street <br />File No. OOOI39-OSOOO-0 <br />Plat No. OS-3097 <br />Dear Janice: <br />We have reviewed the site plans and preliminary plat dated S-4-0S for the proposed improvements to 174S Fox Street <br />The plans propose to subdivide an existing single family lot into a six lot single family subdivision. The existing lot is <br />S7.9I acres of which 21.11 acres are dry. We have the following comments with regards to engineering matters: <br />• The plat should provide drainage and utility easements S-feet wide along all interior lot lines and 10-feet wide <br />along all righbH)f*way. Drainage easements should be provided over all ponding areas, wetlands and drainage <br />ways. <br />• Ptoise see the attached drainage and ponding comments from Lance Hoff. <br />• Because the improvements will disturb more than one acre the final plans should include a detailed temporary <br />and permanent erosion and sediment control plan as required for the NPDES permit The latest plan submittal <br />does not include this information and we are unable to comment on this part of the plan at this time. <br />• The proposed retaining walls exceed 4-feet in height in many areas and approach 10-feet in height in some <br />areas. A separate engineered design and detail submittal is required for all walls that are greater than 4-feet in <br />height <br />• The driveway shown across Outlet A to serve Lot 6 should be configured to serve the existing guest house if <br />this structure is to remain. The existing elevations indicate that a driveway could be constructed between the <br />guest house and the driveway that serves Lot 6 at grades that do not exceed 10%. The guest house access onto <br />Fox Street should be remov^ and the ditch regraded. <br />• The propoaed improvements to Fox Street include lengthening the existing vertical curve from I SO-feet to 300- <br />feet The existing 150-foot vertical curve on Fox Street does not meet the sight distance requirements for a 30 <br />mph design speed. The propoaed improvements to Fox Street will improve the sight distance and will meet the <br />30 mph design standard. Final plans for the Fox Street improvements should include a more detailed design <br />including cross sections at SO-fbot intervals and a proposed pavement section. Final plans should include a. <br />detailed traffic control and detour plan. <br />If you have any questions please call me at (651) 604-4863. <br />Yours very truly. <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES.
