CC Regular Session Meeting Date: 06/24/2025 Primary Strategic Plan Initiative: Address infrastructure needs. 5. 12. Title: Adopt Resolution #25-139 Ordering Plans and Specifications for Flintwood Hills 2nd & 3rd Street Reconstructions, Improvement Project #26-05 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #25-139 ordering plans and specifications for Flintwood Hills 2nd & 3rd Street Reconstructions, Improvement Project #26-05. Background: The 2025 — 2034 Capital Improvement Plan (CIP) identifies the streets within the Flintwood Hills 2nd & 3rd subdivision for street reconstruction in 2026. A street segment summary for the project is attached to this case. Project History • On April 22, 2025, the Ramsey City Council adopted Resolution #25-082, accepting and awarding a proposal to Bolton & Menk for topographic survey of the project area. • May 13, 2025, the Ramsey City Council adopted Resolution #25-101, accepting and awarding a proposal to Independent Testing Technologies for a geotechnical report of the project area. • June 17, 2025, the Ramsey Public Works Committee recommended City Council order plans and specifications for said improvements. Project Scope This project proposes to reconstruct the streets within the Flintwood Hills 2nd & 3rd subdivision, generally located east of Dysprosium Street between CSAH 116 and Nowthen Boulevard (CSAH 5). The subdivision does also include 142nd Avenue west of Dysprosium Street up to Flintwood Park. The streets are 30-foot wide urban section with concrete curb and gutter, totaling 0.83 miles in length. There is no sidewalk in the subdivision other than the intersections with Dysprosium Street. Any pedestrian ramp updates would be tied to Dysprosium Street, rather than this project. Traffic counts have not been taken within the project area. Municipal sewer, water, and storm sewer exist within the project area. Utility testing will be performed during project design, utility improvements are not currently proposed. Storm sewer catch basin grouting and casting resets are typically performed with reconstruction projects. The streets within Flintwood Hills 2nd & 3rd were constructed between 1985 and 1987, no overlay has been performed on these streets. Ground Penetrating Radar (GPR) data taken prior to skim patching shows an average pavement section of 6.6-inches, including 2.5-inches of bituminous and 4.1-inches of aggregate base. The reconstruction is proposed to be a Full Reconstruction in the CIP. A Full Reconstruction typically includes replacing the concrete curb and gutter, and building back a full street section. This causes for greater impacts to adjacent boulevards and driveways, but all work will still be within the City -owned right of way. During project design, staff will review the existing concrete curb and gutter to determine if spot replacement would be sufficient. However, based on the GPR data there's not a thick enough existing pavement section to perform a typical FDR improvement, which will require additional subgrade excavation to create enough depth for the typical neighborhood pavement section. A Full Reconstruction is generally 30 to 40-percent more expensive than an FDR project.
