body
Summary
As a result of a settlement between the California Sportfishing Protection Alliance (CSPA) and the City of Stockton (City), the City was required to implement action plans for sewer pipe rehabilitation and replacement projects. On April 1, 2016, a Request for Proposals (RFP) for professional services for an Asset Management and Master Plan for the Gravity Sewer Collection System was advertised on the City’s Bid Flash webpage. The Asset Management and Master Plan aims to identify and prioritize capital improvement projects for the replacement and repair of the City’s gravity sewer collection system.
Seven proposals were received and evaluated with the three highest ranked firms invited to interview and present their proposals. At the conclusion of this process, HDR Engineering, Inc. of Folsom, CA was the most qualified and highest ranked firm. It is recommended that Council approve a Professional Services Agreement, in the amount of $332,000, with HDR Engineering, Inc. The proposed management and master plan is anticipated to be complete by Fall 2017.
DISCUSSION
Background
The City operates and maintains 878 miles of gravity sewer pipes, 30 miles of pressurized force mains (from 27 pump stations), and 554 miles of lower laterals. Thus the total quantity of sewer system that the City is responsible for is approximately 1,462 miles.
CSPA filed a lawsuit under allegations that the City had violated the Federal Clean Water Act (Act). In the suit, CSPA alleged that the City violated the Act by causing the occurrence of an excessive number of sanitary sewer overflows from the City’s sewer system and that those overflows were harmful to the environment. On July 28, 2009, the City Council approved by Resolution 09-0248 a settlement resolving litigation, in the form of a Consent Decree between the California Sportsfishing Protection Alliance (CSPA) and the City of Stockton (City). This settlement agreement required the City to implement many programs and actions including:
• Reporting annually to CSPA
• Cleaning the entire sewer pipe network
• Instituting the Fats, Oils, and Grease Program (FOG)
• Implementing action plans for sewer pipe rehabilitation and replacement projects
• Capturing internal pipe conditions video data on closed circuit television (CCTV)
This last action is what gave the City the intent of this project, which is to evaluate and consolidate all CCTV data into a single data repository, develop risk models, and prioritize capital improvement projects and budgets for the replacement and repair of the City’s gravity sewer collection system. It is with this intent that the awarded consultant would provide the following deliverables included in the scope of work:
• Import the video data (CCTV) into a specialized asset performance modeling software.
• Develop likelihood and consequence risk failure models.
• Develop short term (1-5 years) and long-term (5-20 years) replacement plans for planning and budgeting purposes.
• Create a sustainable, trackable, strategic plan to address structural pipeline shortfalls.
As of May 30, 2016, the City has exited the Consent Decree. The required annual report for year ending December 31, 2015, stated that the City had satisfied the 5 sanitary sewer overflows (SSOs) per 100 miles of pipe requirement. The City had reduced the SSOs from a high of 8.7 SSOs per 100 miles of pipe in 2009 to 3.3 SSOs per mile in 2015.
Present Situation

Staff evaluated and ranked all seven proposals based on weighted criteria such as: Project Approach and Understanding, Project Team Experience, Technical Team Experience with subject matter, and Project Team References.
On June 15, 2016, the three highest ranked firms were invited for a presentation and discussion interview. All of the three remaining firms proved equally qualified to perform the specifications of the proposed tasks. However, HDR Engineering, Inc. (HDR) exceeded the criteria by further proposing an organizational management plan of our maintenance crew team, utilizing a previously developed specialized software, and enlisting a local engineering firm, Kjeldson, Sinnock & Neudeck,Inc (KSN) of Stockton, CA, for assistance and coordination with this Project. Staff reviewed the cost proposal of HDR and negotiated a suitable fee that was within range of the Engineer’s estimate listed in the proposal details above.
Staff recommends that Council approve a motion authorizing the City Manager to execute a Professional Services Agreement (Attachment A) with HDR Engineering, Inc. for the Asset Management and Master Plan for the Gravity Sewer Collection System Project (PUR16-001). The project will commence upon Council’s approval and be completed during the Fall of 2017.
