June 27, 2018 Centerville City Council Page 4 of 8 Bay View Villas-Comprehensive Plan Amendment, Rezoning, Planned Unit Development, &Preliminary Plat parcel needs to conform to the shoreland standards for removal or alteration of vegetation, particularly limiting vegetation clearing within 50 feet of the ordinary high water line. The homes on the lots adjacent to Centerville Lake do not meet the 75-foot setback, minimum lot size, and minimum width.They average 50-60 feet from the ordinary high water line, are 10,000 square feet, and 62 feet wide. However, most other existing homes adjacent to the lake do not meet the 75-foot setback so this development would be in keeping with the shoreline's existing character. The preliminary plat indicates significant grading and elimination of most mature vegetation within 50 feet of Centerville Lake's ordinary high water line. Runoff directly to the lake is primarily from rooftops and yards (and not driveways), so this is better than if the street and driveways drained to the lake and may be acceptable to the watershed district, but the plan still does not meet the spirit and letter of the Shoreland standards. Planned Unit Development A PUD needs to meet the following standards for a CUP approval: (A) The development shall be planned so that it is consistent with the city comprehensive plan: The PUD will be consistent with the comprehensive plan once a Comprehensive Plan Amendment has been approved through the Metropolitan Council. (B) The PUD is an effective and unified treatment of the development possibilities on the project site and the development plan provides for the preservation of unique natural amenities such as streams, stream banks, wooded cover, rough terrain and similar areas; One of the benefits of a PUD is to provide flexibility in a site plan to preserve natural amenities. While the plan does not meet the specific requirements of the shoreland provisions for setbacks and lot size, it can still meet the intent of the ordinance to preserve the body of water and shoreline. A significant drawback of the proposed preliminary plat is the grading and removal of existing vegetation within 50 feet of the ordinary high water line on Centerville Lake. These changes could not only impact the character of the shoreline, but also have negative consequences on the lake from stormwater runoff. Additionally, units 1,2, and 3 in Block 1 are proposed in a 100-year floodplain but are mitigated through a separation from Centerville Lake's ordinary high water line within 30-75 feet of a flood mitigation zone. Construction of these units will require FEMA approval and vacation of an existing DNR easement. (C) The planned unit development proposal appears to harmonize with both existing and proposed development in the area surrounding the project site; The development proposal is consistent with the single-family residential directly to the east of the property and across Main Street to the north. (D) The tract of land shall be under unified control at the time of application and scheduled to be developed as one unit. In addition, the development plan must include provisions for the preservation of natural amenities; /,Mh r;� IN' ii.jl I f Ir? "1Ind 46
