Once the full size plans arrive I can sign off on the permit.

This would not be allowed without a Conditional Use Permit (CUP). • Additional grading needs to be shown on the northeast corner of the house to reflect the drainage being maintained on the existing property. The 948 contour will need to be adjusted and potentially additional survey will be required to show the proposed grading plan can maintain a swale down this property line. • I believe the intent of the drainage on the east side of the property is to drain to the low area south of the house. Has the proposed 6" pipe been designed by a registered professional engineer to make sure it can handle the runoff from a 100yr event(rainfall or snowmelt)without impacting the proposed structure? This will need to be signed off by a registered professional engineer. • The retaining wall on the southwest corner exceeds 4' in height. The applicant will need to submit plans and specifications from a registered professional engineer for the retaining wall. • The silt fence shows it is extending significantly into the 0-75' zone. Is it the intent of the applicant to regrade to install sod or seed? If so this should also be included in the earthwork calculations. If the calculation exceeds 10 CY, a CUP will be required. • Are all the easements shown on the survey? Along the north side of the property there is an existing watermain and sanitary sewer, but no easement is shown. This should be included on the survey.
