Description/Analysis
IssueDetail
Issue Detail: The Richards Boulevard/I-5 Interchange provides primary access to the Railyards and River District redevelopment areas from Interstate 5. Full build-out of these districts will add numerous residences, retail, entertainment venues and businesses, resulting in a substantial increase of traffic in the area. Operation of the Richards Boulevard/I-5 interchange ramps is currently deficient as indicated by lengthy traffic queues onto mainline Interstate 5 and Richards Boulevard during peak hours. The situation will continue to worsen as redevelopment occurs in the area unless improvements are made to the interchange.
On January 8, 2019, a professional services agreement was executed with WSP USA, Inc. (City Agreement 2019-0042) to provide professional services to complete preliminary engineering and environmental documentation for the Richards Boulevard/ I-5 Interchange Project (T15165100)(“Project”). The Project will improve existing and anticipated operational deficiencies and provide for better bicycle and pedestrian access through the interchange along Richards Boulevard to the waterfront and existing trails. Without the Project upgrades and improvements, traffic congestion levels are anticipated to result in gridlock throughout the River District.
This is a Federal-Aid project on the Interstate Highway System. As the assigned National Environmental Policy Act (NEPA) oversight agency, Caltrans, through technical staff review, has directed the City to make changes to the Project with unanticipated iterations of reviews on the Geometric Approval Drawings, Design Standard Decision Document, Draft Project Report, Right of Way Data Sheets, Preliminary Drainage Report, and Stormwater Data Report. Staff have previously reallocated budget on the contract to pay for these additional review cycles, which has exhausted the contract budget. Caltrans has confirmed that this is their last round of review comments, and approval of Supplemental Agreement No. 20 is required to address the final comments on the Project and circulate the Project’s environmental document.

EnvironmentalConsiderations
Environmental Considerations: The proposed action is an administrative activity and is not a project as defined in CEQA per CEQA Guidelines section 15378(b)(2). The Richards Boulevard/I-5 Interchange project (T15165100) is currently under environmental review and is anticipating an Initial Study - Mitigated Negative Declaration (IS-MND) for CEQA and an Environmental Assessment - Finding of no Significant Impact (EA - FONSI) for NEPA. WSP USA is preparing a joint CEQA/NEPA environmental document per Caltrans guidelines.
End
Sustainability
Sustainability: The Project is consistent with the City’s Sustainability Master Plan goals to promote and incentivize infill development through investment in infrastructure and encouraging mixed-use and high-density development that incorporates a compatible and complimentary mix of residential and non-residential uses.

End
RationaleforRecommendation
Rationale for Recommendation: While preparing environmental technical studies for the Project, Caltrans requested unanticipated, additional reviews of submittals. Approval of Supplemental Agreement No. 20 is needed to address the final comments on the technical studies and route the draft environmental document.
End
FinancialConsiderations
Financial Considerations: The total estimated cost for the PA&ED phase of the Richards Boulevard/I-5 Interchange Project (T15165100) is approximately $6.2 million. There is sufficient funding within the Richards Boulevard/I-5 Interchange Project to execute Supplemental Agreement No. 20 with WSP USA for $154,000, for a new contract not-to-exceed amount of $4,320,656 and complete this phase of work.
There is no general fund allocated or planned for this project.
