Cirilli. Attorno- with Briggs & Morgan, P.A. (the_ "Applicant's C'ounser: spoke with Kyle Klatt, the Planning Director for the City of Lake Elmo (th "Planning Director"), on behalf of the Applicant. Applicant's Counsel discussed Applicant's pursuance of a variance under Section 154.017 or the Lake Flmo Zoning Code. Applicant's Counsel inquired regarding, the current standard 'Or variances applied by the City of Lake Elino. The Planning, Director confirmed that the "practical difficulties- standard, as discussed in Minnesota Statutes 461357, had been adopted by the Cit\, and incorporated into Section 154.017 of the 'Lake Elmo Zoning Code. The Planning Director stated that. the Property had been characterized as a non -buildable lot since 1979, but acknowledged that the Property was improperly assessed and taxed as a buildable lot during the Applicant's ownership of the Property. Applicant's Counsel explained to the Planning Director that the Property Nvas being assessed and taxed as a buildable lot when the Applicant purchased the Property, and as a result, the Applicant believed she was buying, land with hILlable lot value, Applicant's Counsel explained to the Planning Director that the Properly \vas of little or no value to the Applieant or anyone else without eharactcrization as a buildable lot because the Applicant \vas interested in transferring the Property via her estate to her children for buildable purposes. The Planning Director acknowledged the erroneous taxation of the Property, despite stating that the coning classification of the property is separate and distinct from the taxation of the parcel meaning that the fact that the Property was taxed as a buildable lot does not change the fact that it was characterized as unbuildable under the zoning code. The Planning Director contirmed, however, that thc fact that thc Applicant purchased the parcel al. a buildable lot price and for buildable lot value would be considered hv the Planning Commission in its decision ovhether or not to grant a variance The Planning Director explained that he was not sure how much application ol" the new "practical difficult es" standard would affect the Planning Commission's analysis and issuance of variances. fhe Planning Commission has not had many variance applications come before it since the new standard took effect. The Planning Director informed Applicant's Counsel that, if the Planning Commission_ were to grunt a variance for the Propem,. work would have to he commenced on the Property within 12 months attic date the variance was granted otherwise. the variance would expire. Applicant's Counsel responded that this may be an issue for Applicant, and an additional variance may be requested to waive this requirement Hie Applicant also separate]) had conversations with the City regarding her Property. In par. ar, the Applicant spoke with Dean /uleger. the City Administrator for the City of Lake 16C3008N BRIGGS A ri MORGAN K_ylealt February 3, 2014 Paoe 7 Elmo, who intOrmed the Applicant that he was unaware of any: ...:sties with the buildable nature of the Property. Mr Zuleger acknowledged that other buildable lots in the area were of a similar sizc to the Property and that he did not see any reason why the -Property should not bc buildable as \veli. The discussions with Mr, Zuleger also revealed a prior variance that was issued for the Property in 1985_ Upon following up with the Planning Director, there was not much intOrmation on file with the City regarding said variance. only that a variance was issued at that iime regarding the buildable nature of the Property, 'This prior variance supports the current application for a variance for the Property, The Applicant's Counsel further had discussions with Mr. Klatt regarding a variance passed by the. Lake Elmo City Council on October 15, 2013, which variance was passed despite a recommendation from the Planning Commission to deny such variance. The property related to the variance request \vas of a considerably smaller size than the Applicant's property and was located on the shoreline. Mr. Klatt explained that the primary reason for granting the variance was that the propert\ had room for adequate septie systems, and as a result the City Council passed the variance, BRIGGS AN) IV1ORGAN Kyle Klatt February 3, 2014 Page 8 EXHIBIT F frxplanation -)CApplica I's Practical Difficulties) Section 154.017 or the Zoning. Code states that a variance shall be granted "where strict enforcement or the [Zoning Code' \,yould cause practical difficulties because of circumstances unique to the individual property under consideration and then only when it is demonstrated that, such actions will be in keeping with the spirit and intent of this chapter." Under this Section, the "practical difficulties- standard means that "the property owner proposes to use the property in a reasonable manner not permitted by an official control.' The Applicant is proposing to use the Property in a reasonable manner not permitted by an official control. At 0,785 acres. the Property has been characterized as a non-buildahlc lot by the Zoning Code, which has a buildable lot size requirement liar existing, tots of 0,90 acres. The Applicant is proposing to reclassify the Property as a buildable, lot prior to her conveyance of the Property through her estate., Given that the Property's acreage constitutes roughly 87% of the buildable lot size requirement, thc Property is very close to meeting the required buildable lot size under the /onine_ (ode. As a result, it is unlikely. that any structure built on the Property (that complied with the /oning Code's building requirements) would he notably more obstructive than structures built on lots meeting the ininimom 0,90 acre requirement. Property is zoned for residential use and the Applicant Witi have no use for the Property if it is not classified as a buildable lot. The other lots surrounding the Property are not much larger than the Property and were grandlathercd in under the Zoning Code, as the Property at issue should have been, The Property was a platted lot approved by the City at its current size and was intended to be buildable, Therefore, classifying the Property US a buildable lot will not alter the "spirit and intent of the chapter," Cr ten that. the proposed use of the Property is not unreasonable and that the Property should have been previously grandfathcred in under the Zoning Code, the Planning Commission should grant a variance riven the particularly unusual circumstances of the Applicant. as described on Exhibit G. 40 BRIGGS Ar rvi ORGAN Kyle Klatt February 3, 2014 Page 9 BIT G (Fxplanation of Applicant's lnique Cre Section 1:54.017 of the Zoning ('ode further states that u variance shall only be granted whereL1 he pliglit of the landowner is duc to circumstances unique to the property- not created by the landowner.- The Applicant at issue has particularly unusual circumstances, which arc not by fault of her own. The Applicant was not the subdivider of the surrounding development and therefore did not create the problem. At. the time the Applicant purchased the Property in 1985, the Applicant believed the Property \vas buildable. 'ale Property was platted and approved by the Cite at its current size, the surrounding lots were of a similar size and were characterized as buildable. The Applicant paid a buildable lot value for the Property and has been paying taxes. assessed by Washington County, 'vlinncsota, on that buildable lot value for the past twenty-seven (27) years. As a result, the Applicant had good reason to believe that she owned buildable land. The Applicant's belief that the land was buildable affected her decision to purchase and retain the Property. The. Propert\., was specifically characterized as an assesable lot on the City's assessment role on September 10, 1985. at which time the City held a meeting for approval of a special assessment by local property owners By characterizing the Property as im assessable lot, the City was acknowledging the value the Property was receiving from City improvements and assessing. a tee on the Property tbr those improvements. The Property does not. however, receive any value from City improvements it is not also buildable. As a result, the City's characterization ()raw Property as an assessable lot suggests that the Property as intended to be buildable as well. The Applicant had no reason to believe that her land was not buildable, Any plight of the Applicant was due to the error of other parties. As a result, the ,Applicant has unique circumstances that she has not created and which ju.stify the City's mint of a variance for the Property, BRIGGS ,',Nf.) MORGAN Kyle Klatt February 3. 20 I 4 Page 10 (Esscii.ia1 Character of' NeiLOiborltood) In order to obtain a variance from the City. the Applicant is required to show that the iSSUarlet2 Ut' a variance would not alter the essential character or the neighborhood in which the Property is located. In other words, the Property must be consistent and not interfere with the USC Of the property surrounding it. The Property is located in Krause's Addition of the City of lake Elmo. Other lots within Krause's Addition that have houses built on them are not discernibly different in size than the Property, Is previously stated, many of these lots were grandfathered in when the 'toning Code requirements changed, and the Property at issue should have been grandlathered in as well. Furthermore, Ole City Council recently granted a variance on October 15, 2013 for a lot of a considerably smaller sire than the .Applicant's properly, constituting approximately 0.4 acres of land. The City Council's primary reason for granting the variance was that the property had adequate room for appropriate septic systems on the property. The Applicant's Property also has adequate room for appropriate ,septic systems on the property. with room for both a primary and backup drainiield location. as demonstrated by the septic design submitted in connection with the applieation. In addition, unlike the property at SSue in the October 15, 2013 variance request, the Applicant's properly is not located on 111C shoreline and therefore any building on the Applicant's Property won't. interfere with any of the neighboring property rights associated therewith. Springborns Green .Acres, which adjoins the Property to the North, contains two lots (Lot 2 and Lot 3) that both have less buildable area than the Property at issue, due to drainage and utility easements that bisect each lot. Lot 2 and Lot 3 are shown to each constitute 1.6 acres, but their buildable lot areas are actually only 150 feet by 170 feet duc to the casements burdening each lot. Therefore, if granted a variance. the buildable lot area of the Property at issue would he greater than that of both Lot '2 and Lot 3 in Springborn's Green Acres. Given the size of lots surrounding the Property and adequate room tOr appropriate septic systems on the property. the issuance of a variance for the Property \you'd not alter the essential character of the neighborhood.
