CITY COUNCIL AGENDA ITEM NO. 28


Meeting Date: July 22, 2008

Subject/Title: Adopt a Resolution approving and authorizing the City Manager or designee to execute a Joint Exercise of Powers Agreement between the City of Brentwood and the State Route 4 Bypass Authority for the 48” raw waterline in the Laurel Road extension.

Prepared by: Paul R. Eldredge, Assistant Director of Public Works/Assistant City Engineer

Submitted by: Bailey Grewal, Director of Public Works/City Engineer

RECOMMENDATION
Adopt a Resolution approving and authorizing the City Manager or designee to execute a Joint Exercise of Powers Agreement (“Agreement”) between the City of Brentwood and the State Route 4 Bypass Authority for the 48” raw waterline in the Laurel Road extension.

PREVIOUS ACTION
The State Route 4 Bypass Authority (“Authority”) was created by the County of Contra Costa, City of Brentwood (“City”), and City of Antioch on February 28, 1989, through a Joint Exercise of Powers Agreement (“JEPA”) as a public entity to perform project approval and environmental documentation (“PA&ED”) for the construction of a new local road, approximately 20 kilometers (12.4 miles) in length, which will serve as a State Route 4 Bypass (“Bypass”).

Seven amendments to the original JEPA were executed between October 23, 1990, and September 28, 1999, which extended the Authority’s term to January 1, 2015, and expanded the Authority’s function and role beyond PA&ED to also include design, right-of-way, construction, route transfer activities, and added the City of Oakley as a fourth party to the original JEPA.

BACKGROUND
The Authority, under its terms and conditions, is to develop, design and construct the Bypass from the existing State Route 4 (“SR4”) in the City of Antioch along a new alignment through Contra Costa County and the Cities of Antioch, Brentwood and Oakley to the existing SR4 – Byron Highway.

Segment 2 of the Bypass (from Lone Tree Way south to Balfour Road) is complete and open for traffic. The construction for Segment 1 (from existing SR4 in the City of Antioch to Lone Tree Way) is complete and open for traffic and Segment 3 is currently under construction. The construction contract for Segment 3 (from Balfour Road south to existing SR4 – Byron Highway) was awarded on September 21, 2006, and is expected to be open for traffic in September/October 2008.

The Laurel Road extension project was constructed as a part of Segment 1 of the Bypass project and included the widening of Laurel Road from a semi-rural two lane roadway to a six lane facility including drainage, lighting and potable waterlines. These improvements extended from Segment 1 of the Bypass to Empire Avenue in the City of Oakley adjacent to the existing Randall-Bold Water Treatment Plant owned and operated by the Contra Costa Water District (“CCWD”) as well as the proposed new surface water treatment facility that is currently under construction by CCWD and the City of Brentwood as a joint venture (“CBWTP”). The raw water to be treated at the CBWTP is conveyed through a 48” diameter welded steel pipe from the Contra Costa Canal (“Canal”) to the CBWTP. The Canal is located on the north side of Laurel Road while the CBWTP is on the south side, requiring the new pipeline to be installed across the area the Authority was going to be widening.

Initially this raw waterline was going to be bid and constructed as a part of the CBWTP; however, the construction schedule of the Bypass and Laurel Road overlapped with the construction schedule of the CBWTP and, more specifically, the installation of this raw waterline. The installation of the raw waterline was anticipated to be slow, tedious work due to the extensive welding and mortaring of each joint as well as the depth of the pipe, which averaged 12 to 20 feet. To minimize the potential for coordination conflicts, delays and cost overruns associated with having two separate contractors working in the same area, the City has requested the Authority to construct this raw waterline in conjunction with the Laurel Road improvements. Thus an agreement was prepared between the Authority and the City outlining the financial and agency responsibilities for the ultimate construction of the raw waterline as part of Segment 1 of the Bypass. The Authority will be responsible for the construction of the raw waterline and preparation of the necessary easement documents. The City’s responsibility includes reimbursing the Authority the sum of $997,610 to cover design, construction and construction administration for the raw waterline.

Staff recommends the approval of this Agreement between the City and the Authority for the installation of the raw waterline.

FISCAL IMPACT
The amount of $997,610 has been anticipated and budgeted for in the adopted 2008/09 – 2012/13 Capital Improvement Program Budget under the Surface Water Treatment Facility, Phases I and II, CIP Project No. 562-56290.
