CITY OF REDDING
REPORT TO THE CITY COUNCIL
Recommendation
Authorize the following actions relative to Request for Proposals (RFP) No. 5094, to provide engineering services for the Pump House 1 Replacement Project:
(1) Award to Jacobs;
(2) Authorize the Mayor to execute the Consultant and Professional Services Contract with Jacobs for Phase 1 (preliminary design) of the project, including project management, data review, geotechnical investigations, survey/mapping, preliminary environmental review, construction financing evaluation, and preparation of a preliminary design report for replacement of Pump House 1 for a not-to-exceed fee of $488,829; and (3) Authorize the City Manager to approve contract amendments not to exceed $150,000.
Fiscal Impact
The total project costs are expected to be roughly $30 million. Funding for this project will come from the Water Utility Fund and the project is included in the current Capital Improvement Program. The City of Redding (City) plans to obtain State or Federal loans and/or grants, with the design consultant’s assistance, to fund a portion of the construction costs for the project.
Should funding from loans or grants not materialize, the City may need to issue municipal bonds.
Alternative Action
The City Council (Council) may choose not to award the contract for Phase 1 preliminary design services for the project. This alternative will delay or eliminate the construction of the Pump House 1 Replacement Project subjecting the City’s water system to significant vulnerabilities and potential regulatory action.

Re: 4.11(d)‐‐Award Request for Proposals No. 5094 Page 2
Background
The City’s water system includes two water treatment plants, approximately 555 miles of conveyance and distribution pipelines, 17 groundwater wells, 10 pump stations, and 12 reservoirs providing a total of 33.5 million gallons of storage. The City’s Pump House 1 (PH1) is located on the south bank of the Sacramento River, along the Sacramento River Trail and approximately 1/4 mile upriver from the Diestelhorst and Lake Redding Bridges. It pumps water from the Sacramento River to the City’s Foothill Water Treatment Plant (FWTP), its largest and primary water supply, providing more than half of the City’s drinking water during average and peak demands. PH1 is the only source of raw water to the FWTP, making it a very critical component of the City’s water supply chain.
PH1 was constructed in 1937, and has been in continual service since that time. Major modifications were performed in 1968, 1981, and 1989, to replace aging pumps and add new pumps to increase the station’s capacity. It currently has five vertical turbine pumps and its firm capacity is approximately 28.9 million gallons per day (MGD).
In 2002, a feasibility study entitled “Draft Feasibility Study for the City of Redding Pump House No. 1 Fish Protection Project” (Feasibility Study) was prepared for the City by CH2M Hill (now Jacobs). Available funding was insufficient at that time to construct a new pumping facility or even to complete many of the recommended modifications. Therefore, the City was directed by National Oceanic and Atmospheric Administration (NOAA) Fisheries to pursue an interim retrofit solution for fish screening, which was installed at PH1 in 2006. However, the retrofitted screens depart from standard criteria under certain river and operating conditions and as such are not a long term solution.
City staff plans to completely replace PH1 because of the following general deficiencies:
Its intake is located in a shallow area of the river that impacts its capacity depending on the status of the Anderson Cottonwood Irrigation District (ACID) dam downriver. The existing intake and screens may not meet long term state and federal criteria regarding protection of endangered fish species.
Its capacity will need to be increased to meet the future capacity of the FWTP. Based on the City’s General Plan seismic hazard map, it is located in an area of high seismic liquefaction potential and may not be adequate to withstand critical damage during a design earthquake.
City staff will consider four project alternatives, or combinations thereof, for replacement of Pump House 1, including:
Replacement at the existing Pump House 1 location;
Replacement at a new river trail location, approximately 2,000 feet upriver; Replacement at the Keswick Reservoir; and
Replacement with a riverbank filtration collector well system.
Design services for the PH1 replacement will be broken into two phases. Phase 1 of the design is included in the attached Consulting and Professional Services Contract. It will include preliminary design services for evaluation of the project alternatives, and preparation of a preliminary design report to allow the City to determine the appropriate project alternative to pursue.

Re: 4.11(d)‐‐Award Request for Proposals No. 5094 Page 3
Phase 2 of the design is not included in the attached Consulting and Professional Services Contract. It will involve the detailed design, environmental compliance documentation, permitting, project funding assistance, right-of-way acquisition, preparation of contract documents, and design services during the bid and construction periods for the selected project alternative. If the City is satisfied with Jacobs’ services at the completion of Phase 1 (expected spring of 2021), then staff intends to recommend at that time that the Council authorize negotiation for an amendment with Jacobs to add Phase 2 design services to the Contract.
Otherwise, a separate RFP will be required for Phase 2 engineering services.
CONSULTANT SELECTION PROCESS
A review and selection panel was formed with five members from the Public Works Water and Engineering Divisions. The panel’s evaluation was based on consultants’ ability and qualifications to perform all phases of the engineering services that will be required, including both Phases 1 and 2.
Four proposals, including design fees in sealed envelopes, were received on January 24, 2020.
The panel members evaluated and scored each proposal based on consultants’ understanding of the project/scope, project approach, experience with fish screens, experience with riverbank filtration collector wells, qualifications of the project team and manager, familiarity with City projects and required procedures, ability to complete projects on-time and within budget, and the proposed teams’ location. After reviewing the proposals, the panel elected to interview all four of the firms that proposed.
Oral interviews were held on March 12, 2020, at City Hall. Each consultant team was allowed 55 minutes to provide a presentation and answer the City’s questions. The questions asked were the same for all consultant teams and were not provided to any team until they arrived for the interview; at which time, each participant was provided the questions in writing. Review Panel members evaluated and scored each consultant team based on their presentation and responses to the questions.
After the oral interviews, the review panel:
Combined scores from the consultants’ proposals and oral interview to determine their overall score;
Ranked consultants based on their overall score; and
After ranking, opened consultant’s sealed fee envelopes.
The panel ranked the firms as follows:
Rank Firm Fee
1 Jacobs $488,829
2 Black & Veatch $576,210
3 West Yost $997,956
4 Stantech $1,160,516
Applying the evaluation criteria to the proposals and oral interview scoring, it is the opinion of the selection panel that Jacobs is the most qualified team to provide the required services. This opinion is in part based on Jacobs’:
Excellent fish screen and riverbank collector well design experience and qualifications; Environmental and compliance team has a proven track record with similar projects; Packet Pg. 624 Attachment: Previous Staff Report- 5/5/2020 (9.11(c)--Authorize Fifth Amendment to Consulting and Professional Services Contract C-8541) Report to Redding City Council April 28, 2020
Re: 4.11(d)‐‐Award Request for Proposals No. 5094 Page 4
Design experience in the Sacramento River near the project area; Creative design approach and ideas presented in their oral interview; and Local team.
Replacement of Pump House 1 has been included in the City’s Water Master Plan for several years and is a necessary and critical improvement for the City’s water supply chain. Staff believes that Jacobs is the most qualified team to provide the required design services and recommends that the Council authorize recommendations listed herein, including award to Jacobs’ for an amount not-to-exceed $488,829.
