The existing lot is <br />37.91 acresofwhkh2l.ll acres are dry. We have the following comments with regards to engineering matters: <br />The plat should provide drainage and utility easements 3-feet wide along all interior lot lines and 10-feet wide <br />along all rights-of-way. Drainage easements should be provided over all ponding areas, wetlands and drainage <br />ways. <br />Please see the attached drainage and ponding coimnents 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 walla 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 />beighL <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 bouse 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 proposed improvem e nts to Fox Street include lengthening the existing vertical curve from 130-feet to 300- <br />fbei The existing 130-fbot vertical curve on Fox Street does not meet the sight distance requirements for a 30 <br />mph design speed. The propoeed improvements to Fox Street will improve the sight distaiKe and will meet the <br />30 mph design standard. FiiMl plans for the Fox Street improvements should include a more detailed design <br />iiKhidirig cross sections at 30-foot intervals and a proposed pavement section. Final plaiM should include a <br />detailed traffic control and detour plan. <br />If you have any questions please call me at (631) 604-4863. <br />Your very truly. <br />BONESTROO. ROSENE.
