TWO TO CONTRACT K-1415-91: BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND URBAN CONTRACTORS, L.L.C., INCREASING THE CONTRACT AMOUNT BY $166,950 FOR A REVISED CONTRACT PRICE OF $3,145,424 ON THE SEWER MAINTENANCE PROJECT FYE 2013 AND BUDGET TRANSFER FROM A SEWER MAINTENANCE FUND CAPITAL PROJECT.

BACKGROUND: In 2001, the citizens of Norman approved a five dollar ($5) per month sewer maintenance fee to provide for the systematic rehabilitation or replacement of aged and deteriorated sewer lines throughout our wastewater collection system.
