[Ord. No. 45, art. XIV, eff. 10-15-1973; Ord. No. 45-1, eff. 7-25-1980]
(a) 
The township board may authorize a variance of any of the engineering standards established or may waive the installation of an improvement when it determines that undue hardship or practical difficulty necessitates such variance or waiver. In granting such variance or waiver, the board shall prescribe other conditions that it deems necessary or desirable for the public interest. No variance shall be granted unless the township board finds:
(1) 
There are special circumstances or conditions affecting the project improvement such that a strict application of the provisions of this article would deprive the applicant of reasonable use of his property; and
(2) 
That the variance is necessary for the preservation and enjoyment of the substantial property right of the applicant; and
(3) 
That the granting of the variance will not be detrimental to the public welfare or injurious to other property in the area in which such property is situated; and
(4) 
That an alternate standard or material proposed by the applicant provides the same functional equivalency as the standard or materials required by this article, and that the alternate standard or material will provide a useful life of the improvement equal to the expected useful life of such improvement had such improvement been installed in strict conformity with this article.
(b) 
Application for any such variance shall be submitted in writing by the owner at the time the preliminary plans are submitted, stating fully and clearly all facts relied upon by the owner and shall be supplemented with maps, plans, or other additional data which may be in the analysis of the proposed project. The plans for such development shall include such covenants, restrictions or other legal provisions necessary to guarantee the full achievement of the plan.
