Relief, waiver, or exemption. Any applicant desiring relief, waiver or exemption from any aspect or requirement of this section may make such request at the preapplication meeting or, subsequently, to the Board of Trustees. Any request for waiver or exemption from any aspect of this section shall be contained in the original application. Such relief may be temporary or permanent, partial, or complete. However, the burden of proving the need for the requested relief, waiver or exemption is solely on the applicant to prove. The applicant shall bear all costs of the Village in considering the request and the relief, waiver, or exemption. No such relief or exemption shall be approved unless the applicant demonstrates by clear and convincing evidence that, if granted, the relief, waiver or exemption will have no significant effect on the health, safety and welfare of the Village, its residents and other services or the ability of the Board of Trustees to conduct its review pursuant to this section.
