end
PURPOSE/ACTION REQUESTED
Authorize the execution of an engineering contract with Stonebrooke Engineering, Inc., for preliminary and final design engineering for a roundabout at the intersection of County State Aid Highway (CSAH) 50 and Hamburg Avenue in the City of Lakeville (Attachment: Location Map).
SUMMARY
To provide a safe and efficient transportation system, Dakota County staff continuously monitors intersections within the County for deficient characteristics and provides recommendations for action if necessary. The intersection of CSAH 50 and Hamburg in Lakeville has exhibited crash patterns and frequency, as well as increased traffic demand due to increased development within the immediate surrounding area. County staff coordinated internally and with the City of Lakeville to determine that a project was necessary to address issues exhibited and increase safety. To pursue corrective action, the 2024 Transportation Capital Improvement Program Budget was amended by Resolution No. 24-071 (February 6, 2024) to add County Project (CP) 50-37 to install a roundabout at the CSAH 50 and Hamburg Avenue intersection. Construction for CP 50-37 is planned to occur in 2026.
Scope of Work: The preliminary and final design scope of work for CP 50-37 consists of roadway design engineering services, surveying, utility coordination, drainage design, environmental review, right of way coordination, traffic analysis, lighting analysis, and landscaping for the reconstruction of the CSAH 50 and Hamburg Avenue intersection. The consultant will include a public participation process, which consists of property owner meetings, two open houses, and an online engagement effort aimed at gathering public feedback and garnering support.
Consultant Selection: Staff issued a request for proposal for preliminary and final design engineering services to three consultants on April 11, 2024. Three proposals were received and evaluated by City and County staff. Stonebrooke Engineering, Inc. was selected as the preferred professional engineering consultant based on their quality of response for project understanding, proposed project approach, project team, performance on similar projects, and best value cost proposal (Attachment: Consultant Selection Summary). The three cost proposals received are noted below.
