Description/Analysis
IssueDetail
Issue Detail: Additional engineering, construction management, inspection, and material testing services are necessary to complete the Sump 151 and Sump 155 Outfall Replacement Projects in the Drainage Sump R&R Program (W14130600) due in large part to construction taking longer than expected. Staff recommends Council approve both Supplemental Agreements No. 1 with Brown and Caldwell and Supplemental Agreement No. 11 with Peterson Brustad, Inc. (PBI).
In addition, staff recommends a budget transfer of $570,000 from Base CIP Contingency-Drainage Program (W14000200, Fund 6021) to Drainage Sump Replacement/Rehabilitation Program (W14130600, Fund 6021) to provide sufficient funding to complete the projects.

PolicyConsiderations
Policy Considerations: The proposed supplemental agreements and budget transfers exceed the City Manager’s approval authority, requiring Council approval per City Code 3.04.020.

EnvironmentalConsiderations
Environmental Considerations: Per the California Environmental Quality Act (CEQA)
Guidelines Section 15061(b)(3), approval of the proposed Supplemental Agreements are exempt from the CEQA, under the general rule that CEQA only applies to actions with potential to significantly affect the environment. Approval of this Supplemental Agreement for additional
engineering services will not affect the environment. Improvements associated with this project were evaluated in a mitigated negative declaration (MND) that was adopted by City Council on August 10, 2021 (Resolution No. 2021-0245).

Sustainability
Sustainability: The proposed project is consistent with the 2040 General Plan <https://www.cityofsacramento.gov/community-development/planning/long-range/general-plan/2040-general-plan> under policy PFS-3.1 as it improves pumping capacity for peak storm flows, improves service and infrastructure reliability, and increase redundancy.

Commission/Committee Action: Not applicable.

RationaleforRecommendation
Rationale for Recommendation: The Department of Utilities (DOU) owns, operates, and maintains the 106 drainage sump stations within the city. The outfalls from the sump stations are the single point of discharge for storm water from their respective basins. The outfall pipes penetrate and cross major levees along the Sacramento River, American River, Natomas East Main Drainage Canal, Arcade Creek, and Morrison Creek.
City staff has an ongoing requirement to inspect all outfalls that penetrate and cross major levees on a 5-year cycle as mandated by the US Army Corps of Engineers (USACE). During inspection of several outfalls, many were noted to be in failing condition or in danger of imminent failure. Peterson Brustad Inc. was hired to provide design and construction engineering services for the replacement of those outfalls, which included Sumps 155 and 151 . A construction contractor was hired at the beginning of 2024 to complete the replacements for 151 and 155, and Brown and Caldwell was subsequently hired to provide inspection and construction management. Construction has gone slightly longer than anticipated so additional funds are needed to allow Brown and Caldwell to continue construction management and inspection to assist in close out of the project.
The supplemental agreements will provide additional engineering design and construction support services, and construction management, inspection, and materials testing services for the Sump 151 and Sump 155 Outfall Replacement projects.

FinancialConsiderations
Financial Considerations: There are three proposed supplemental agreements included for approval related to the Drainage Sump R&R Program (W14130600) as follows:
Brown and Caldwell City Agreement 2024-0041 is for the Sump 151 Outfall Replacement Project with an original not-to-exceed amount of $242,714. The proposed Supplemental Agreement No. 1, in the amount of $156,274, will increase the agreement not-to-exceed amount to $398,988.
Brown and Caldwell City Agreement 2024-0969 is for the Sump 155 Outfall Replacement Project with an original not-to-exceed amount of $242,523. The proposed Supplemental Agreement No. 1, in the amount of $75,210, will increase the agreement not-to-exceed amount to $317,733.
Finally, the Peterson Brustad, Inc. City Agreement 2020-1399 is for the Pump Outfalls Replacement Project with an original not-to-exceed amount of $710,829. The proposed Supplemental Agreement No. 11, for an amount not to exceed $46,242, will increase the agreement’s total not-to-exceed amount to $1,617,676.
In addition, a budget transfer of $570,000 from Base CIP Contingency-Drainage Program (W14000200, Fund 6021) to Drainage Sump Replacement/Rehabilitation Program (W14130600, Fund 6021) is required to provide sufficient funding for the completion of the Sump 151 and Sump 155 Outfall Replacement Projects.
There are no General Funds planned or allocated for this project.
