The Board shall have the power to hear and decide all applications for special exceptions to the terms of this chapter in such cases as are herein expressly provided for in other sections of this chapter in harmony with the general purpose and intent of this chapter, with the power to impose appropriate conditions and safeguards as the Board may deem necessary for the protection of adjacent properties and the public interest. In considering such applications, the Board shall give due regard to the nature and condition of all adjacent uses and structures and in interpreting and applying the provisions of this chapter they shall be held to be the minimum requirements for the promotion of the health, safety, morals and general welfare of the Borough. In addition, the Board shall consider whether said exception shall result in an unreasonable density of population in relation to municipal water and sewers available, whether the existing highways are adequate to serve such exception without causing traffic congestion or unusual noise or any noise which shall annoy, disturb, injure or endanger the comfort, health, peace or safety of others in the operation of such activity.
