Feasibility Report 2021 Downtown Improvements City of Hugo, MN WSB Project No. 015887-000 Page 3 3 EXISTING CONDITIONS 3.1 Surface Streets in the project area currently vary in width from twenty to twenty-four feet (20’ - 24’), with some areas having dedicated public right of ways and others where the City has prescriptive rights, areas having been used and maintained for a minimum of six (6) years. The total length of roadway included in the project is approximately 5,900 feet, or 1.12 miles. 2021 Downtown Improvement Project Existing Conditions Street Segment From To Length Existing Width Curb 147th Street West of TH 61 Finale Avenue 1,060’20’-24'None 147th Street Extension Finale Avenue Oneka Boulevard 1,265’N/A N/A Flay Avenue 147th Street Existing Termination 500’20’None Upper 146th Street Fitzgerald Avenue Finale Avenue 715’24’None 146th Street West of TH 61 Finale Avenue 920’24’None Finley Avenue 145th Street Upper 146th Street 700’24’None Fitzgerald Avenue 146th Street 147th Street 740’20’None The project street segments had improvements in the 1970’s, 80’s, and early 90’s. Since then, pavement conditions have aged and are exhibiting distresses such as transverse and longitudinal cracking, pavement rutting, and a fallen cross slope, with surfaces rated as fair to poor. Pavement cores taken within the project area indicate the existing asphalt thickness ranges from two- inches (2”) to four-inches (4”) and the aggregate base thickness ranges from two-inches (2”) to ten-inches (10”). A copy of the pavement core results is included in Appendix D of this report. 3.2 Drainage Runoff currently flows along the sides of the street pavement and is collected by the existing storm sewer drains in several locations. The existing street grades, inlet locations, and drainage patterns do not allow for efficient, timely drainage during heavy rain events. Existing storm sewer pipe systems split the project with surface water on Upper 146th Street west of Finley Avenue, Finley Avenue, and 146th Street flowing south to the system in 145th Street. Surface water on Upper 146th Street east of Finley Avenue, Fitzgerald Avenue, 147th Street, and Flay Avenue flows north and outlets into the City owned open space north of St. Johns Cemetery. Drainage from the location of the proposed extension of 147th Street drains west across a currently open field to Judicial Ditch 3 Branch 3 which is maintained by the Rice Creek Watershed District (RCWD). There is FEMA floodplain and floodway present at the location of the 147th Street extension. 3.3 Private and Non-City Utilities Private utilities that have facilities in or near the project area will be notified during the final design phase of the project and will be requested to coordinate any necessary repairs and replacements as needed at their cost.
