DISCUSSION: Attached is the proposed ordinance adopting the 1988 Uniform Mechanical Code. This is in keeping with the policy of regularly updating the Building Code of the City of Fort Worth. The Mechanical Board has revised the ordinance to include changes primarily for the purpose of clarification and to gain a closer uniformity with the Uniform Mechanical Code. A Public Hearing was held by the Mechanical Board of Appeals on Wednesday, November 14, 1990. No one appeared in opposition to the proposed ordinance therefore, the Mechanical Board recommends City Council adoption.
