40A, to grant upon appeal or upon petition with respect to particular land or structures a variance from the terms of this chapter, expressly including variances for use or activity not otherwise permitted in the district in which the land or structure is located, upon a specific finding that, owing to circumstances related to soil conditions shapes or topography of such land or structures and especially affecting such land or structures, but not affecting generally the zoning district in which it is located, a literal enforcement of the provisions of this chapter would involve substantial hardship, financial or otherwise, to the petitioner or appellant, and that desirable relief may be granted without substantial hardship, financial or otherwise, to the petitioner or appellant, and that desirable relief may be granted without substantial detriment to the public good and without nullifying or substantially derogating from the intent or purpose of this chapter.
