PROBLEM/ISSUE STATEMENT
Staff is requesting that the City Council authorize a contract amendment for professional services with Morrison-Maierle, Inc. to provide engineering services for W.O. 12-31 East End Industrial Area Storm Drain. The purpose of this project is to alleviate surcharging and flooding of the storm drains in 4th and 6th Avenues North. The original contract included an engineering study to determine the alignment, verify the size, and ascertain the constructability for crossing the MRL railroad tracks for the new storm drain pipe. Contract amendment No. 1 included the design and construction administration for the new storm drain, as well as a study on the Yegen Drain to develop potential outfall alternatives that would address capacity issues. Contract Amendment No. 2 was for the design and construction administration for the Yegen Drain option that was determined to be the most cost effective by the study. This Contract Amendment is for the design and construction administration for up-sizing a 36-inch sanitary sewer line in North 15th Street between Montana Avenue and 1st Avenue North. The North 15th Street Interceptor Upgrade was identified in the 2006 Water and Waste Water Master Plan. This one block section of sewer main is near capacity under current peak flow conditions and since the East End Industrial project is installing storm drain and waterline in this section of North 15th Street, it is more efficient to upgrade the sewer line at that time.
ALTERNATIVES ANALYZED
The Council may:
- Approve the Professional Services Contract Amendment No. 3 with Morrison-Maierle; or,
- Do not approve the Professional Services Contract Amendment No. 3 with Morrison-Maierle. If this contract amendment is not approved, surcharging of the sewer line may occur.
FINANCIAL IMPACT
Funding for Contract Amendment No. 3 will be out of Sewer Funds. Contract Amendment No. 3 is in the amount of $28,966.00. The total contract, including this amendment, with Morrison-Maierle, Inc. is $1,607,214.00.
RECOMMENDATION
Staff recommends that Council authorize the Mayor to sign Contract Amendment No. 3 for professional services with Morrison-Maierle, Inc. for W.O. 12-31 East End Industrial Area Storm Drain in the amount not to exceed $28,966.00.
