Plat Map&Properry Owners List Backgraund This�roperty,one of Orono's few remaining large lakeshore estates,consists of approximately 31 acres, bordered on the north by Tanager Lake and the Dakota Rail Trail, and on the south by County Road 15 (Shoreline Drive) and Smith's Bay of Lake Minnetonka. The owner has chosen to spli� off three new 2-plus acre lakeshore residential iots, each with frontage on Tanager Lake. The existing residence and accessory buildings will remain with approxixnately 13 acres of dry builc�able land which could be further subdivided in the firture. All 3 new lots are proposed to be accessed via an extension of Heritage Lane, a public road extending from County Road 15. The property was ad.ded to the Metropolitan Urban Service Area (�VIIJSA) in 20Q1 in order to allow the installation and use of municipal sewer. A113 new lots are intended to be served with municipal sewer and private wells. Conformity with the Qrono 2030 Community Management Plan The proposed 4-lot subdivision is in conformity with the guiding of this area for single family lakeshore residential development at a density of 1 unit per 2 acres. Conformity with Zoning Dist�rict Lot Requirements The property is in the LR-1A, Single Family Lakeshore Residential District, which allows for single family residential uses requiring a minimum lot size of 2 dry buildable acres and a minimum lot width of 200' as rneasured at the lakeshore and at the 7S' lakeshore setback line. The preliminazy plat indicates the area and width r�quirements will be met for each praposed lot The property is within both tl�e Shoreland Overlay District and the defined Stormwater Quality Overlay District, and is therefore subject to hardcover regulations. Each iot appears to have a suitable building site meeting the minimum front, sicie, side street and rear setbacics of the LR-lA District, Note that the Dakota Rail Trail is considered as a side street for setback purposes for proposed Lot 1. Each new lot is large enough to have no problem meeti.ng the 25% hardcover limitation. The developer has been advised that unless site grading to create individual hause building pads as part of the subdivision improvements is proposed, the existing grades for measuring building heights and number of stories will be the grades that exist today. Raised pads that are created must be acknowledged in the development approval stage as creating`new exist�ng grades'. I�'o grading of individual pads is currently indicated on the prelimiz�ary plat drawings. Relationship to Surrounding Development The proposed single-family development is consistent with existing development in the surroundi.ng neighborhood. Similar single family lots with 2-plus acre lot sizes exist to the east and southwest,while the lots wit.hin the adjacent Foxhill neighboz'hood(Heritage Drive and Lane) average approximately 1.05 acres,having been created in 1965 per the I-acre zoning then in effect.
