Any existing development as defined in this chapter, may be continued and maintained subject to the provisions provided herein. Expansions to structures classified as existing development must meet the requirements of this chapter, however, the built-upon area of the existing development is not required to be included in the density calculation.
(A) Vacant lots. This category consists of vacant lots for which plats or deeds have been recorded in the office of the Register of Deeds (Davidson County). Lots may be used for any of the uses allowed in the watershed area in which it is located, provided the following:
(1) Where the lot area is below the minimum specified in this chapter, the Watershed Administrator is authorized to issue a watershed protection permit; and
(2) Whenever two or more contiguous residential vacant lots of record are in single ownership at any time after the adoption of this chapter and such lots individually have less area than the minimum requirements for residential purposes for the watershed area in which such lots are located, such lots shall be combined to create one or more lots that meet the standards of this chapter, or if this is not possible, reduce to the extent possible the nonconformity of the lots. (Lots of record depicting 20,000 square feet and valid approved preliminary plats are excluded).
(B) Occupied lots. This category consists of lots, occupied for residential purposes at the time of the adoption of this chapter. These lots may continue to be used provided that whenever two or more adjoining lots of record, one of which is occupied, are in single ownership at any time after the adoption of this chapter, and such lots individually or together have less area than the minimum requirements for residential purposes for the watershed area in which they are located, such lots shall be combined to create lots which meet the minimum size requirements or which minimize the degree of nonconformity.
(C) Uses of land. This consists of uses existing at the time of adoption of this chapter where such use of the land is not permitted to be established hereafter in the watershed area in which it is located. Such uses may be continued except as follows:
(1) When such use of land has been changed to an allowed use, it shall not revert to any prohibited use;
(2) Such use of land shall be changed only to an allowed use; and
(3) When such use ceases for a period of at least six months, it shall not be reestablished.
(D) Reconstruction of buildings or built-upon areas. Any existing building or built-upon area not in conformance with the restrictions of this chapter that has been damaged or removed may be repaired and/or reconstructed, provided that:
(1) Reconstruction is initiated within six months and completed within two years of such damage; and
(2) The total amount of space devoted to built-upon area may not be increased unless stormwater control that equals or exceeds the previous development is provided.
