In order to provide for a smooth transition to new standards, grandfathering provisions shall apply as follows to preexisting development and shoreland uses established prior to November 1, 1999, which are located along or adjoin TVA-owned access residential shoreland.
(b) Grandfathered structures may continue to be maintained in accordance with previous permit requirements, and TVA does not require modification to conform to new standards.
(c) If a permitted structure is destroyed by fire or storms, the permit shall be reissued if the replacement facility is rebuilt to specifications originally permitted by TVA.
(d) Vegetation management at grandfathered developments shall be as follows:
(2) At sites where mowing of lawns established prior to November 1, 1999, is not specifically included as an authorized use in an existing permit, TVA will include mowing as a permitted use in the next permit action at that site.
(3) The SMZ is not required where established lawns existed prior to November 1, 1999.
(4) Any additional removal of trees or other vegetation (except for mowing of lawns established prior to November 1, 1999) requires TVA's approval in accordance with § 1304.203. Removal of trees greater than three inches in diameter at ground level is not allowed.
