Each development proposal shall demonstrate that it will not adversely affect the existing loads on the public water and public sewer systems of the Town. The Department of Public Works or the Department of Public Works' agent shall serve to determine what is the existing load on the public water and public sewer systems of the Town. In the event that the applicant is unable to demonstrate that there will be no adverse effect or if the Department should find there will be an adverse impact, the Department may require the applicant to redesign the development proposal to minimize such impact and may require the applicant to proceed with development in phases as specified by the Department. The Department may specifically require a development density less than that otherwise permitted under this bylaw. In the alternative, the applicant may offer to fund any required capital improvements deemed necessary by the Department to handle the increased water and sewer demands of the proposed development, and the Department may require bonding in an amount sufficient to provide adequate security to the Town for the completion of said capital improvements. Any such capital improvements will be subject to the approval and continuing review of the Department of Public Works.
