Temporary construction trailers and one sign not exceeding 32 square feet, advertising the prime contractor, subcontractor(s), architect, financing institution and similar data for the period of construction beginning with the issuance for a construction permit and concluding with the issuance of a certificate of occupancy or one year, whichever is less, are permitted, provided said trailer(s) and sign are on the site where the construction is taking place and are not on any existing street or easement or within any "critical" area.
The Township Construction Official may issue one year extensions, upon written request by the developer, for the continuation of the temporary construction trailers and sign.
