The typical side yards easements shown are 10 feet; however, they should be 5 feet. Amended Grading Plan Comments: 1.

It does not appear that the proposed contour tie into the existing contour north and south of the proposed improvements. The grading plan needs to clearly demonstrate how the proposed grading will tie into the surrounding property. 3. The proposed grading doesn't appear to work from a drainage perspective for a number of the lots. There proposed grades for the front yards are at the same elevation as the street there by creating flat front yards and driveways. The proposed house pads likely need to be adjusted (raised) to create positive drainage for all of the lots. 4. A Rice Creek Watershed District permit will be required as part of this project.
