4 s, I • J 10 City of Mounds Vlew Staff Report Item No: 9D Meeting Date: September 11 2017 Type of Business: C� Administrator Review: To: Honorable Mayor and City Council From: Don Peterson, Interim Director of Public Works Item Title/Subject: Resolution 8827 Authorizing Preparation of Feasibility Report and Pavement and Soil Borings for Program Ave, Quincy St, Woodale Dr., Clifton Dr. (Aka Business Park North) Pavement Rehabilitation. Background/Discussion: The Business Park North area is due for street reconstruction. The Business Park North consists of the following streets: Program Ave, Quincy St, Woodale Dr. and Clifton Dr. These streets are North East of Mounds View Blvd and West of 35W. These street segments serve twenty seven companies ranging from industrial, light commercial, medical technologies, manufacturing and several fast food restaurants; there are two nonprofit organizations located in this business park as well. Quincy St., a state aid road, is also a major arterial road from Mounds View Blvd to County Rd. I. Many of these properties have consistent and high truck traffic as well as the general public entering and exiting the business. Maintaining access to and limiting interruptions for these properties during the construction is important and will require a phased approach. Further Discussion: Program Ave. is approximately 2,600 feet in length and Woodale Dr. from Mounds View Blvd. to Program Ave., is approximately 800 feet in length, Quincy St. from Mounds View Blvd to H2 is approximately 1,521 feet in length and Clifton Dr. is approximately 224 feet in length. All street segments have concrete curb and gutter with a bituminous pavement surface measuring 60 -feet wide (lip -to -lip of gutter); the streets were originally constructed in the mid 1980's. Maintenance includes a seal coat in 1993 and 1998 along with pothole patching and skim coating as needed. The current pavement is in poor condition with significant surface patching, potholes, and moderate to high severity traverse cracking. Curb and gutter is in fair to good condition. In 2011, American Engineering Testing, Inc. (AET) performed geotechnical and pavement evaluation services on behalf of the City for Program Ave. AET's ten pavement cores showed bituminous pavement thickness ranging from 4.75 to 1.5 inches and found stripping at multiple layer interfaces. AET recommends a pavement rehabilitation design (10 -ton, 20 -year ESAL of 2,000,000) as follows: 1. Reclaim the existing asphalt and a portion of the aggregate base to the depth of 6 inches; 2. Remove the reclaimed asphalt pavement to a depth of 5 inches; 3. Place the following surface: 3.0 inches Bituminous Wear (mix SPWE13340C) placed in 2 lifts 2.0 inches Bituminous Non -Wear (mix SPNWB23OB) It is expected that there will be some sections of curb and gutter needing replacement or correction, however, the majority of curb and gutter is expected to remain undisturbed. In order to properly design the streets additional core samples need to be obtained. At this time
