5.1. Public Works Committee Meeting Date: 04/15/2025 Primary Strategic Plan Initiative: Address infrastructure needs. Title • Consider Recommending City Council Order Plans and Specifications for MSA Bunker Lake Boulevard Reconstruction, Improvement Project #26-01 Purpose/Background: Purpose: The purpose of this case is to consider recommending city council order plans and specifications and award the engineering design proposal from Bolton & Menk, Inc. for MSA Bunker Lake Boulevard Reconstruction, Improvement Project #26-01. Background: The 2025 — 2034 Capital Improvement Program (CIP) identifies Bunker Lake Boulevard between Armstrong Boulevard and 600 feet west of Jackal Street (the tie-in point from the 2018 project) for reconstruction in 2026. A street segment summary is attached to this case. Project Scope This project proposes to reconstruct this city -owned segment of Bunker Lake Boulevard in a similar fashion to the previously reconstructed Bunker Lake Boulevard and Puma Street segments. The existing street is 28-feet wide with concrete curb and gutter on the north side (westbound) and rural section including a drainage swale on the south side (eastbound). The project proposes expanding the pavement to the south, to create a shared center turn lane. The new eastbound lane is proposed to include concrete curb and gutter, the existing drainage swale is also proposed to be replaced with underground storm sewer piping. Bunker Lake Boulevard is an MSA street, which will require it to be built to MSA standards, including a 10-ton pavement strength design. Bituminous trail exists on the north side of Bunker Lake Boulevard, the project does not propose to improve the existing trail. The western half of this segment has been developed with commercial/industrial users. The eastern half is generally not developed, a gas station is currently being proposed at the southwest corner of Bunker Lake Boulevard and Armstrong Boulevard. Coordination with proposed developments will be required during the project design. The project totals 0.47 miles in length. Utilities Sanitary sewer, watermain and storm sewer exist within the project area. Additional storm sewer will be required to replace the existing swale on the south side of Bunker Lake Boulevard. At this time, repairs to the existing sewer and watermain are not anticipated. However, the existing utilities will be tested during project design. If damage is found, the necessary repairs will be incorporated into the project. Project Timelines Due to heavy workloads, staff proposes to enlist Bolton & Menk, Inc. prepare plans and specifications for this project. A proposal from Bolton & Menk, Inc. for engineering design services, including preparing final plans and specifications, is attached to this case. The following are the proposed general project timelines: April 22, 2025 City Council authorization to prepare plans and specifications Spring 2025 Geotechnical investigation (RFP) and topographic survey (Bolton & Menk) Summer 2025 Utility Testing (RFP) Summer/Fall 2025 Prepare plans and specifications (Bolton & Menk) Fall 2025 City Council approves plans, authorizes bidding
