When the approval requires the meeting of conditions, construction of improvements or corrections, or time is necessary for improvements or corrections, or time is necessary for the obtaining of required certifications, then the approval action shall be conditional approval which shall, at the option of the approving body, be conditioned upon fulfillment prior to the final approval of a site development permit or building permit or upon fulfillment within six months. Upon application within the six-month time period and upon good cause shown, the approving body may grant one six-month extension. (Ord. 1110 § 2, 2002).
