FILE #LA24-000059 <br />18 November 2024 <br />Page 3 of 7 <br /> <br /> <br /> <br />Rural Oasis + Conservation Design + Wetlands <br />The Developer’s engineer, Civil Methods prepared a Conservation Design Master Plan (“CDMP”) for the <br />development following the Conservation Design requirements outlined within Chapter 78, Article XII (beginning <br />with Section. 78-1631). The Idyllvale Shores CDMP is attached as Exhibit I and reviewed the development against <br />the City’s Rural Oasis Study and provided an overview of the property relating to Drainage, Land Use, Natural <br />Resources Inventory, Public Waters Inventory, and Wetlands. <br /> <br />The property was not one of the <br />development sites analyzed in <br />Orono’s 2005 Rural Oasis Study <br />(R.O.S) and was not situated along an <br />identified rural oasis corridor. Their <br />CDMP acknowledges that this <br />property is partially located within a <br />greenway corridor, and contains <br />areas of maple-basswood and oak <br />forests with the potential to contain <br />rare species. The developer did not <br />survey the rare species but rather <br />ensured that proper protective <br />measures would be taken if rare <br />species were encountered during <br />development. <br /> <br />According to the CDMP report, the <br />plans prioritize the preservation of the existing woodland and wetland areas and the maintenance of the existing <br />natural ecological connections. <br /> <br />Landscaping + Tree Preservation <br />City Code Section 82-225(b) stipulates deciduous trees (“boulevard trees”) are to be planted within five feet of the <br />right-of-way of the roads within and abutting the subdivision. One tree shall be planted for every 40 feet of <br />frontage along each road. A plan has been provided for tree preservation and removals (Exhibit N), and a <br />development landscaping plan reflecting the installation of 55 trees consisting of a mix of honeylocust, oak, and <br />maple is attached as Exhibit O). The tree preservation and removal plan identified 1,206 total trees on the <br />property; 419 trees are to be removed due to their condition or location within the development. The plan reflects <br />2,180 linear feet of road frontage requiring 55 trees. According to their schedule, the developer is proposing to <br />plant 55 trees in a relatively uniform placement along the western road and more selectively placed along the <br />northern road, likely to avoid the proposed stormwater infiltration area. <br /> <br />Lot Layout + Lot Standards – LR-1A, Lakeshore Residential and RR-1B, Rural Residential <br />The LR-1A and RR-1B districts each have a minimum lot area requirement of 2.0 dry, contiguous acres and 200 feet <br />in width for each newly created lot. See Exhibit P for clarification of the district boundary line between the two <br />districts. Please review Exhibit F for a full breakdown and code analysis of the proposed lots. <br /> <br />According to the City Code, lot width for non-lakeshore lots in either district is measured at the 50-foot front <br />building setback paralleling the roadway. For lakeshore lots, the minimum 200-foot width is measured in a straight <br />line between the points where the side property lines intersect the 929.4’ OHWL contour for Lake Minnetonka, and <br />in a straight line measured at the required 75-foot structure setback from the OHWL. <br /> <br />95
