2.3 The applicant proposes a five to six foot elevation increase from lona Lane to the northern most point of the cul-de-sac, with lookout and walkout lots being graded into the site to match existing contours on the parcel. 2.4 The existing parcel drains to the north, northwest and northeast. Drainage for the parcel when development is complete will match into existing contours on adjacent parcels and drain in a similar direction. No storm water management pond has been designed for the development. The grading and drainage plan must be reviewed and approved by the Roseville Engineering Department to ensure that it is consistent with Grass Lake and Roseville storm water management plans prior to final City Council approval. 2.5 Sanitary sewer and water main will be provided from lona Lane within the proposed cul- de-sac street with individual service connections to each residential lot. 2.6 A 30-foot wide front, rear, and street side (comer) setback has been proposed (and is required) on the site plan.
