PURPOSE:
Approving the third amendment to the Professional Services Agreement (PSA) with HDR Engineering, Inc. for services on the Mineral Station West Multimodal Improvements Project.
LONG-TERM OUTCOME(S) SERVED:
Safe Community; High-Quality Governance
DISCUSSION:
The Mineral Station West Multimodal Improvements Project, City Project No. 23-36, will provide critical missing multimodal connections between the regional trail and transit network adjacent to Santa Fe Drive, and improve access and mobility to and from the Mary Carter Greenway and South Platte River Trail, and other activity centers such as the Carson Nature Center and Aspen Grove Mall. The project will also connect housing units currently being constructed south of the project area and planned residential units to the north with nearby commercial destinations and transit services, strengthening overall network connectivity. This project is part of a larger program of multimodal transportation projects around Littleton/Mineral Station area served by the Regional Transportation District (RTD) D light rail line that collectively will provide improved first and last mile connections to transit, provide high-comfort bike and pedestrian facilities between commercial and residential development (existing and planned), and create safer access to recreational assets. Additionally, the project will create a more direct, Americans with Disabilities Act (ADA)-accessible route to the Littleton/Mineral light rail station and an improved connection to the residential, commercial, transit, and recreational amenities with safer, comfortable, and dedicated bike and pedestrian facilities.
In 2023, City staff selected HDR Engineering (HDR) for professional consultant services to complete the design for the project. In May 2023 a contract was executed with HDR for the first phase of the project (conceptual design).The contract with HDR was first amended in 2024 to begin the second phase of the project to include additional scope and budget for preliminary and final design. The second amendment to the contract was approved in February 2026 to extend the timeline through February 2027. The proposed third amendment will add additional scope and budget, and extend the design services contract to December 2027, to complete the final design and provide design support services during construction, as described in the attachment.
The conceptual and preliminary (30 percent) design is now complete, which included engagement with South Suburban Parks and Recreation Department (SSPRD), RTD, and other area stakeholders. HDR has refined the design scope and fee to complete the remaining design for the project as reflected in this contract amendment for council approval.
There are cost savings and efficiencies of utilizing HDR’s design services for the Mineral Station West Improvements Project as HDR is the design engineering consultant as well as the Owner’s Representative for the Santa Fe and Mineral Improvements Project. HDR’s services during another project in the area provides significant familiarity with the transportation challenges and opportunities in the vicinity as well as use of previously gathered and analyzed data.
If Council approves this resolution, the project team will continue with completing the remaining design, with anticipated completion in late 2026. Construction of the project is anticipated in summer 2027.
BACKGROUND:
The City of Littleton and Arapahoe County were awarded a $2.153 million grant in 2022 for the construction of the Mineral Station West Multimodal Improvements Project, which is comprised of $956,000 funded through the Denver Regional Council of Government’s (DRCOG) Transportation Improvement Program (TIP), and $1.197 million from CDOT’s Multimodal Transportation Mitigation Options (MMOF) funds. The focus of this TIP call for projects was on regionally significant projects aimed at improving multimodal facilities and operations. The City of Littleton has been successful in securing TIP funds for several other projects including Santa Fe and Mineral Intersection Improvements, Mineral Mobility East Improvements Phase 1 and 2, Broadway Corridor Study, County Line Trail Connections, County Line Road Widening, and Bowles Avenue Corridor Study.
The Mineral Station West Multimodal Improvements Project will provide critical missing multimodal connections between the regional trail and transit network adjacent to Santa Fe Drive, improving the access and mobility to and from the Mary Carter Greenway and South Platte River Trail, and other activity centers, such as the Carson Nature Center and Aspen Grove Mall. A lack of connectivity and capacity of bicycle and pedestrian facilities leading to and from the Littleton/Mineral Light Rail Station hampers access by alternative modes, resulting in additional use of single-occupancy vehicles parking at the station and driving the Santa Fe Drive and Mineral Avenue corridors.
Multimodal connections are critical to creating an environment in which residents can recreate and commute safely. The Mineral Station West Multimodal Improvements Project will provide safe and accessible routes on which most users will feel comfortable using. This will be accomplished by limiting exposure to and crossing points with vehicles, providing adequate width to maneuver and pass other users. Key stakeholders in the project include, but are not limited to, SSPRD, RTD, adjacent property owners, transit users, cyclists, and pedestrians.
The Mineral Station West Multimodal Improvements Project was also informed by two studies. The Santa Fe Drive Action Plan - A Planning and Environmental Linkage (PEL) Study | C-470 to I-25 (2022) studied and identified future transportation and safety improvements for an 11-mile stretch of Santa Fe Drive between C-470 and Alameda Avenue. Some of the improvements identified in the Santa Fe Drive Action Plan PEL Study informed the Mineral Station West Multimodal Improvements project. The project was also informed by the South Platte Connections Study (2019), to provide one piece of a larger planned trail connection between C-470 to the Aspen Grove Mall and Carson Nature Center, as well as to provide residents east of Santa Fe Drive a clear, safe route to the Mary Carter Greenway and other amenities on the west side of Santa Fe Drive.
Prior Actions or Discussions
August 15, 2023: Council approved Resolution 85-2023, authorizing Intergovernmental Agreement (IGA) with CDOT for design and construction of the Mineral Station West Multimodal Project.
March 5, 2024: Council approved Resolution 14-2024, approving first amendment to the Professional Services Agreement with HDR Engineering, Inc.
FISCAL IMPACTS:
Design of the Mineral Station West Improvements Project is being funded by city funds as described below. A total of $3.3 million of funding resources have been secured for project construction comprised of grant funding (federal and state), and Arapahoe County and City of Littleton local match contributions.
The original contract with HDR Engineering was split into phases. The first phase for conceptual design was $78,378. The fee for the first Amendment to the Professional Services Agreement was for phase 2, preliminary and final design services, was $474,565. The second amendment to the agreement was a time extension only, with no fiscal impacts. The third Amendment, proposed for council approval, is for the additional scope, budget and time to complete final design and provide design support services during construction is $277,312. In aggregate, the total contract value will be $830,255. Pursuant to the City’s new Procurement Policy, all contracts exceeding $500,000 must be approved by City Council.
This contract amendment will be funded from Multimodal Impact Fees ($277,312).
STAFF RECOMMENDATION:
Staff recommends approval of the Professional Services Agreement Amendment.
ALTERNATIVES:
If this contract amendment is not approved, design on the Mineral Station West Multimodal Improvements Project cannot continue. In accordance to the current terms of the Intergovernmental Agreement executed between the City and CDOT for this project, the project must be advertised for construction by June 30, 2026. The City anticipates requesting a time extension from DRCOG to provide additional time to complete design and advertise for construction in early 2027. Any delay of design could place project grant funding at risk.
PROPOSED MOTION:
Proposed Motion
I move to approve Resolution 44-2026 approving the third amendment to the Professional Services Agreement with HDR Engineering, Inc. for design services on the Mineral Station West Multimodal Improvements Project.
