2020 Construction Projects Under Way

2020 Construction Projects Under Way
The City of Columbia Heights Public Works Department has six proposed construction projects slated for 2020, in addition to the Silver Lake Boat Landing project. Please consider using alternate routes while work is being done. Certain sections of the road may be shut down occasionally during the projects. Please obey construction signs and drive slowly through work areas.

Update: The intersection at 43rd Avenue with Benjamin Street and Stinson Boulevard will be closed to traffic beginning Fri, May 29

1) 37^th Ave Street Rehabilitation and Trail Reconstruction
An 8-foot paved multi-use trail will be constructed on the north side of 37^th Ave from 5^th St to Central Ave. The work involves site grading, retaining wall construction, new pedestrian ramps, the construction of an 8-foot wide bituminous trail and restoration. The work is scheduled to begin the week of May 4 and end in 6-8 weeks.

Following the completion of the trail, the City of Columbia Heights and the City of Minneapolis are partnering to resurface 37th Ave NE from 5th St NE to Central Ave NE. This project is a continuation of the 2018 resurfacing that occurred from Main St NE to 5th St NE.

2) 2020 Concrete Alley Reconstruction
Columbia Heights has over 17 miles of paved alleys, with either concrete or bituminous pavement. Due to their deteriorated condition, the following alleys are proposed to be fully reconstructed to a new concrete surface in 2020:

Washington to Jefferson Streets, 41^st to 42^nd Avenues
Madison to Monroe Streets, 40^th to 41^st Avenues
Madison to Monroe Streets, 42^nd to 43^rd Avenues

During reconstruction, crews will remove existing bituminous surface, grade underlying soils, place gravel base, and pour a new concrete surface. Alleys are generally inaccessible during the 30-45 day construction timeframe.

3) 2020 Water Main Replacement
The City has over 66 miles of water main, most of which are 40-60 years old or older. Prior to the mid-1960s, pipe interiors were not coated, allowing water to be in contact with the iron pipe. As a result, rust may build up over time. When particles of this rust break off, discolored or red water may result. To correct this, Columbia Heights partnered with the City of Minneapolis to begin a water main cleaning and lining program. During this process, crews clean the interior of the water main and then install a thin concrete mortar on the inside wall of the pipe to keep the water from touching the iron, which limits rust formation and significantly reduces discolored or red water. Annually, Columbia Heights will clean and line 3,500 to 5,000 lineal feet of pipe under the Minneapolis program. On main segments where water main breaks have a history of occurring, the process of cleaning and lining is not used and the main must be replaced. Due to the number of water main breaks these segments have sustained, the following water main segments will be replaced:

39^th Ave, Johnson St to Arthur St
Arthur St, 39^th Ave to 40^th Ave
Stinson Boulevard at 43^rd Ave

This project will begin once CenterPoint has replaced the existing steel gas mains on Arthur Street, likely in June or July.

4) 2020 Street Rehabilitation Program
In 1997, the City approved an annual street rehabilitation program to address the long term condition and sustainability of the City’s 66 miles of streets. Under this program, the City of Columbia Heights is divided into seven zones. Annually, a condition analysis is conducted for the following year’s zone work. Based on the condition rating, staff recommends one of four treatment types: sealcoating, mill and overlay, partial reconstruction (full depth reclamation) and complete reconstruction. Based on the condition rating, the following streets will be reconstructed:

ZONE 4A:

5^th Street, 50^th to 51^st Avenues, with water main replacement.
6^th Street, 50^th to 51^st Avenues

This project will begin once CenterPoint has replaced the existing steel gas mains, likely in mid-May or June.

5) Traffic Signal Replacement: Central Ave at 41^st Ave (MnDOT project, resumed from 2019)
MnDOT is scheduled to completely replace the traffic signal at this intersection in 2019. The work will include new signal bases, poles and arms, new LED lights, new controller, new LED street name signs, and a new Emergency Vehicle Pre-emption System ("EVP System") and Accessible Pedestrian Signals ("APS"). Work began in 2019 and due to materials availability, was suspended until 2020.

6) 2020 Seal Coat Program
Bituminous streets in the northeast quadrant (Street Rehabilitation Zone 3) of the City will be patched and seal coated this year. Street Department staff will continue patching the streets in May and June. Crack sealing will also be done on select streets in June. Seal coat application (asphalt emulsion and rock) will be applied by the Contractor in late July or early August.
