City Council Draft Agenda
- Meeting Date:
- 06/16/2026
- From:
- Geneva Lanzetta, Capital Improvements Project Manager
TITLE:
Consideration and Approval of Contract: Change Order No. 2 to an On-Call Professional Services Task Order with Ardurra Group, Inc. in the amount of $24,157.00 for the Downtown Lateral – Santa Fe Ave Project, for a total project contract amount of $123,809.79.
STAFF RECOMMENDED ACTION:
- Approve Change Order No. 2 to an On-Call Professional Services Task Order with Ardurra Group, Inc. in the amount of $24,157.00, total project amount of $123,809.79; and
- Authorize the City Manager to execute the necessary documents.
Executive Summary:
The Downtown Lateral – Santa Fe Ave Project requires additional engineering design and modeling services to finalize the stormwater conveyance improvements. These services are being completed under the City’s On-Call Professional Services Contract with Ardurra Group, Inc. (“Ardurra”), formerly Shepard-Wesnitzer Inc., master on-call contract originally approved by City Council and dated December 2, 2022. Ardurra was issued an initial Task Order for design services for this project on September 30, 2024. The additional tasks of Change Order No. 2 include separation of one of the new utility connections from the two phases of work previously identified, water modeling to determine constructibility of a new potable water line configuration requested by the City, and survey of two curb ramps that were previously not included as part of the improvements.
In accordance with City procedures, the Change Order was reviewed and approved by the Change Order Committee on May 28, 2026. Due to this change order bringing the project design total over the $100,000 threshold, it now requires City Council approval.

Financial Impact:
The Project is funded by the Stormwater Fund, with a U.S. Army Corps of Engineers (USACE) Environmental Infrastructure (EI) 595 reimbursement share of $1.2 million. The total budget appropriation in account number 206-09-375-3592-0 is $3,591,700 (includes FY2025-26 estimate and FY2026-27 budget). This total project budget accommodates engineering design, construction administration, permitting, construction, testing and inspection, and Capital Improvements project management costs.
Policy Impact:
No impact.
Previous Council Decision or Community Discussion:
- On July 5, 2022, the City Council approved numerous On-Call Professional Services Contracts; Engineering, including a contract with Ardurra Group, Inc.
- The City Council has previously approved the FY26 Capital Improvements 5-year Plan and authorized the FY26 budget which includes this project.
Options and Alternatives to Recommended Action:
- Approve Change Order No. 2 as recommended. Approval will allow work on the project to proceed without delay; or
- Reject request for approval. This action would delay and/or terminate the Project. If rejection occurs, possible options include:
a. Suspend or cancel the Project.
Background and History:
The Downtown Lateral Project was developed to address drainage and flooding issues affecting the Milton Road/Route 66 corridor, particularly the low point beneath the BNSF railroad bridge, where stormwater originating from the mesa routinely collects during major storm events. To reduce these risks, the project will construct a new box culvert stormwater conveyance that captures runoff from the mesa and directs it safely toward the Rio de Flag.
The project is closely coordinated with the Downtown Mile and Rio de Flag Flood Control improvements to ensure hydraulic continuity and to establish a unified outfall connection into the Rio de Flag. Hydrologic and hydraulic analyses, led by the Downtown Mile team and supplemented with 100-year storm modeling, confirmed the need for a dedicated conveyance to prevent roadway flooding and improve public safety.
The project is currently in the design phases, with ongoing inter-project coordination to refine constructability considerations. This design will provide a long-term solution that supports downtown infrastructure and integrates with the City’s broader flood-mitigation strategy.
Change Order No. 1 was administratively approved on March 28, 2025. The additional tasks included the separation of the project into two phases for construction coordination with the Downtown Mile Project, utility potholing, and cultural/environmental studies requested by the USACE.
