M- OIXe1*1111il]
To keep the Uniform Codes (Building Code, Electrical Code, Plumbing Code and Mechanical Code)
current with the latest technologies, the publishers of these codes issue an updated edition every
three years. In an effort to keep construction consistent throughout the state, the state mandates
that local jurisdictions adopt the most recent editions of these codes in a reasonable time period
following their publication. The proposed ordinance will update the City's Codes to the most recent
1991 editions of these Uniform Codes and amends certain technical sections to reflect local climate,
topographic and geologic conditions. The amendments to the Building Code include adding
chapters on Security Provisions and Grading and Excavation requirements and amending sections
regarding soils containing sulfates and expansive soils, as well as minimum numbers of sanitary
plumbing fixtures, and roof covering requirements for high risk fire zones.
The Plumbing Code was amended to add restrictions on water softener discharges into the water
table and provision to allow residences to recycle graywater for landscape purposes.
A public meeting was held with industry representatives to gain input on the proposed adoption.
No comments to alter the proposed adoption were received.
Copies of the Codes and amendments are available at the Building & Safety public counter and the
City Clerk's Office for public review.
The City Council introduce Ordinance No. 92.19, waive further reading and pass to second reading.
