A. The maximum lot area covered by the building footprint of the Principal Building (as defined in Section 5-103) and all Detached Accessory Buildings (as defined in Section 5-103) on a lot shall be determined by application of the following formula: LCA = 5.29471 (ALSF) 0.695 [Lot Coverage Area equals 5.29471 multiplied by the Actual Lot Square Footage to the power of 0.695].

B. The building footprint of the Principal Building and all detached accessory buildings on a lot shall be determined from the most current Improvement to Land Area Ratio Statistics as developed by the Johnson County Appraiser’s Office; provided that, the City Administrator may determine the building footprint from any other reliable source on a case by case basis.

C. The maximum percentages set forth in Section 5-123.A shall be, as stated, the maximum percentage of lot coverage of the footprint of Principal Buildings and Detached Accessory Buildings on a lot. The fact that a building footprint on a lot is equal to or less than the maximum percentage of lot coverage established for the respective Lot Size shall not create a presumption that the lot coverage of the building footprint proposed in an application being considered by the Architectural Review Board is appropriate for that particular lot. The Architectural Review Board shall consider the proposed lot coverage shown on plans or specifications submitted in connection with an application, and in considering the standards set forth in Section 5-146 and the factors in Section 5-147, may determine that the proposed lot coverage, though equal to or less than the applicable maximum lot coverage percentage set forth in Section 5-123.A, is not appropriate at the proposed location, in light of all the factors to be examined. If the Architectural Review Board so finds, it may condition its approval on a lot coverage percent that is less than the maximum established for the respective Lot Size. [Ord. 1292, 07-12-10.]
