Mr. Jim March <br /> March 18, 1998 <br /> Page Two <br /> • Proposed contours must be labeled throughout the plat. The submitted plan only labels <br /> the contours along the east side of the plat. <br /> • Drainage arrows and spot elevations must be shown at high points and major grade <br /> changes. Drainage arrows and spot elevations must also be shown to indicate where <br /> runoff from the rear of Lots 17 -26, Block 2 drains. <br /> • All existing and proposed easements must be shown. <br /> • Emergency overflows must be labeled and shown with spot elevations and drainage <br /> arrows. <br /> • The ordinary high water level of the wetland and pond must be shown. <br /> • The proposed grading of the rear of Lots 1 -10, Block 2 and Lots 18 -25, Block 2 must be <br /> revised so that runoff runs along the lot lines. It is recommended that a swale be graded <br /> and shown with spot elevations along the lot lines. <br /> As we have previously stated, it is recommended that the grading plan be resubmitted for final <br /> review. Therefore, this review is preliminary and other items /issues may arise during the final <br /> review. <br /> Sincerely, <br /> �io�waa1rrdd�R. Green Company <br /> David E.
