6. 23. CC Regular Session Meeting Date: 11/26/2024 Primary Strategic Plan Initiative: Address infrastructure needs. Title: Adopt Resolution#24-340 Ordering Plans and Specifications for High Point Street Reconstructions, Improvement Project#25-05 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution#24-340 ordering plans and specifications for High Point Street Reconstructions, Improvement Project#25-05. Background: The proposed 2025—2034 Capita Improvement Plan(CIP) identifies the streets within the High Point and Section 22 Unplatted subdivision for street reconstruction in 2025. A street segment summary for the project is attached to this case. Project History •May 28, 2024,the Ramsey City Council adopted Resolution#24-13 8, accepting and awarding a proposal to Hakanson Anderson for topographic survey of the project area. •August 12,2024,the Ramsey City Council adopted Resolution#24-220, accepting and awarding a proposal to Independent Testing Technologies, Inc. for a geotechnical report of the project area. •November 19,2024, 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 High Point and Section 22 Unplatted subdivision, generally located between Ramsey Boulevard and Zirconium Street,between 155th and 157th Avenues. The street within Section 22 Unplatted(156th Avenue) are 26-foot urban with bituminous curbing and rural with drainage swales at the low point. The streets within High Point are 30-foot urban section with bituminous curbing and cross street valley gutters with drainage flumes at low points. The streets total approximately 1.67 miles in total length, traffic counts have not been taken within the project area. Staff is proposing to replace the bituminous curbing with surmountable concrete curb and gutter. Where feasible storm sewer inlets and storm sewer piping will replace bituminous flumes and cross gutters for drainage. This will be further explored during project design. Review of the geotechnical report found clean sands, ideal for pavement support within the project area. Additionally, groundwater is not anticipated to be a concern for the street reconstruction. Staff is proposing a pavement section of 3.5-inches new bituminous pavement over 6-inches aggregate base. The existing pavement section ranges from 6 to 8-inches thick,to achieve the proposed pavement section additional subsoil excavation of 2 to 3-inches will be required. During initial project review, staff has identified the Zirconium Street cul-de-sac in need of further discussion. The current City design standards require cul-de-sacs be built to a 100-foot diameter within a 120-foot right of way. The Zirconium Street cul-de-sac was built to a 165-foot diameter within a 200-foot diameter right of way. Placing the cul-de-sac back to this oversized diameter is not desirable, and staff proposes to explore several replacement options. Staff proposes bringing a separate case to the Public Works Committee and for further discussion once
