Approve two change orders totaling $340,500.50 with R&R Pacific Construction to rehabilitate sidewalks at the Knights Landing Community Park; approve an amendment with Wilson Design Studio Landscape Architecture to increase the contract by $41,605; approve the project budget for the Knights Landing Sidewalk Rehabilitation project; and adopt a budget resolution in the amount of $130,209 to pay for the County's portion of the change order. (No general fund impact) (4/5 vote required) (Pistochini)

The General Services Department is constructing a new community park in Knights Landing, which impacts a portion of existing sidewalk along California State Highway 113 within the California Department of Transportation (CalTrans) right of way and along County Road 116 to the Sci Tech School. CalTrans has had a long-standing desire to update the existing sidewalks and crosswalks per the CalTrans Standard Plan A88A and approached Yolo County to collaborate on this project, which was triggered by the Park's storm drain tie in on California State Highway 113. The work will include approximately 807 feet of sidewalk widening to 8 feet along California State Highway 113 that tapers onto County Road 116, and new ADA compliant ramp enlargement and new 12 foot wide crosswalk striping for the existing crosswalk at Couty Road 116 and Hershey Street. This work was not part of the original scope of work of the Knights Landing Community Park Project.

On February 11th, 2025, the Board of Supervisors approved an agreement between Yolo County General Services Department and CalTrans. This agreement formally established a partnership between Yolo County and CalTrans and defines cost sharing for the required sidewalk rehabilitation. The total cost of the work is estimated to be $351,001, which includes an amendment to the existing Wilson Design Studios contract for an additional $41,605 to continue ongoing coordination and documentation support and a $340,500.50 change order for R&R Pacific Construction to do the work. A portion of the Wilson Design Studios amendment ($30,105) is for ongoing closeout work for the Knights Landing Park project and is unrelated to the Sidewalk Rehabilitation project. This portion will be paid for out of the existing Knight Landing Park project budget.  

Through the attached Budget Resolution, the General Services Department proposes to increase the fiscal year 2024-25 Facilities Capital Project Budget in the amount of $130,209 to appropriate the County's contribution to the Knights Landing Sidewalk Rehabilitation project. The CalTrans contribution of $300,000 was previously appropriated on February 11, 2025. It should be noted that CalTrans' share of the CA 113 sidewalk improvements is $221,792; the remainder of their contribution will be held as project contingency. Since a portion of the sidewalk rehabilitation is related to, and will benefit, the Knights Landing park, staff propose using $76,785 in available contingency funds from the Knights Landing Park project budget to cover a portion of the County's share. In addition, the Department of Community Services Public Works division is contributing $49,424 in Highway Users Tax Account (HUTA) funds, since the new crosswalk at CR 116 and Hershey Street will need to be updated in the near future. Finally, staff propose using $4,000 in Park DIF to fund the remaining balance.

The table below reflects the project budget for the Knights Landing Sidewalk Rehabilitation Project:

CA 113 Sidewalk Rehabilitation	$249,457
CR 116 ADA Improvements	$91,044

KL Park Project Contingency	$76,785
Highway Users Tax Account (HUTA)	$49,424
Park DIF	$4,000

Staff coordinated with the County Counsel's Office, the Department of Financial Services, the Department of Community Services, and the California Department of Transportation (CalTrans).

R&R Pacific Construction was originally selected using a competitive solicitation process and was the lowest bidder.  This change order, as generally is the case, was not competitively solicited, with the detailed analysis for this approach described above.  The total of the two change orders is less than 10% of the construction contract value.  One change order is specific to the work on County Road 116 and the other change order is specific to the work along California Highway 113.

Vendor Performance
R&R Pacific Construction has performed satisfactorily on the current agreement to construct the park. 

Wilson Design Studios has performed exceptionally on the current agreement to design the park and provide construction monitoring support.
