2020 Construction Projects
1) 37th Avenue Street Rehabilitation and Trail Reconstruction
An 8-foot paved multi-use trail will be constructed on the north side of 37th Avenue from 5th Street to Central Avenue. 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 4th and be completed 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 Avenue from 5th Street to Central Avenue. This project is a continuation of the 2018 resurfacing that occurred from Main Street to 5th Street.
2) 2020 Concrete Alley Reconstruction
The City of Columbia Heights has over 17 miles of paved alleys, with either concrete or bituminous pavement. When the City conducted a large alley reconstruction program in 2000, it established that all alleys identified for full replacement will be reconstructed with concrete. 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, 41st to 42nd Avenues
- Madison to Monroe Streets, 40th to 41st Avenues
- Madison to Monroe Streets, 42nd to 43rd Avenues
During reconstruction, the existing bituminous surface is removed, underlying soils are graded, gravel base is placed and a new concrete surface is poured. Alleys are generally inaccessible during the 30-45 day construction timeframe.
3) 2020 Water Main Replacement
The City of Columbia Heights has over 66 miles of water main, with most of the mains installed as the city developed, making them 40-60 years old or older. Prior to the mid 1960’s, pipe interiors were not coated, allowing water to be in contact with the iron pipe. As a result, rust can form and build up over time. When particles of this rust break off discolored or red water may occur. To correct this, the City of Columbia Heights partnered with the City of Minneapolis to begin a water main cleaning and lining program. This process cleans the interior of the water main and then installs a thin concrete mortar on the inside wall of the pipe. This provides a barrier to water contacting the iron pipe, 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 is replaced. Due to the number of water main breaks these segments have experienced, the following water main segments will be replaced:
- 39th Avenue, Johnson Street to Arthur Street
- Arthur Street, 39th Avenue to 40th Avenue
- Stinson Boulevard at 43rd Avenue
This project will begin once CenterPoint Energy 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 7 zones. Annually, a condition analysis is conducted for the following year’s zone work, and based on the condition rating, staff recommends one of four treatment types: seal coat, mill and overlay, partial reconstruction (full depth reclamation) or complete reconstruction. Based on the condition rating, the following streets will be reconstructed:
- 5th Street, 50th to 51st Avenues, with water main replacement
- 6th Street, 50th to 51st Avenues
This project will begin once CenterPoint Energy has replaced the existing steel gas mains, likely in mid-May or June.
5) Silver Lake Boat Landing and Sanitary Lift Station Construction
The City of Columbia Heights owns and operates a public boat launch on Silver Lake located off of Stinson Boulevard, just south of 41st Avenue. The condition of the boat landing dictates full replacement with a redesign to improve the access and maneuverability, and to make the boat launch accessible. An existing sanitary sewer lift station interferes with the access and trailering near the water access. In 2019, the City was awarded a grant to assist with the cost of a new boat landing. Because of the proximity of the lift station, the project combines both the boat launch reconstruction and the relocation and reconstruction of the lift station. The proposed work includes a new boat landing that provides improved access, a large retaining wall that facilitates a larger approach for trailering into the lake, parking down by the boat launch, a small upper parking lot, water quality improvements based on the new pavement, and a small dock to tie off a boat. (Layout Plan)
Construction will begin July 27th . The boat landing will be closed during construction.
6) Traffic Signal Replacement: Central Avenue at 41st Avenue (MnDOT project, resumed from 2019)
MnDOT was scheduled to completely replace the traffic signal at this intersection in 2019. The work includes 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.
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.
8) Pump Station 3
The City of Columbia Heights is performing rehabilitation to the piping, pumps, motors and valves inside of Pump Station 3 located on Ivanhoe Place. Most mechanical components at the station are being replaced to get rid of older equipment and allow for the installation of VFDs (variable frequency drives). The VFDs will be able to deliver water to our water tower at different flow rates, and help reduce water hammer when pumps turn on and off. These improvements will reduce the risk of water main breaks throughout the distribution system, extend the life cycle of the pump station, and ensure the continuous delivery of safe drinking water. The work is scheduled to begin late August or early September.
Future Construction Projects:
Wargo Court Master Plan
Wargo Court Park is a mini-park located at the northwest corner of Central Avenue and 41st Avenue. No major work has been performed at Wargo Court in over 30 years, focusing only on maintaining the park. The primary park feature is the fountain, which is beyond repair and in need of replacement. The electrical serving the site is undersized and old and trips repeatedly. The site amenities such as the retaining walls and landscaping are dilapidated and in need of a complete replacement.
The Park and Recreation Commission has completed master planning of six (6) parks, culminating in the reconstruction of each of these parks. The intent of a Master Plan is to provide a detailed plan of the entire park for redevelopment. Therefore, it is the desire of the Park and Recreation Commission and City Staff to have a detailed working plan to rehabilitate or rebuild elements of the park in phases, as funding becomes available.
University Avenue Trail and Decorative Fence, 37th to 40th Avenues (east)
With recent redevelopment, part of this segment does have paved bituminous trail or concrete sidewalk and a decorative fence north of 37th Avenue. This project would complete the pedestrian connection up to 40th Avenue along with similar fencing to provide separation from University Avenue.
53rd Avenue Safety Improvements: Central Avenue to Sullivan Lake Park
The cities of Columbia Heights and Fridley have received funding to help support the roadway improvements consisting of a raised concrete median, a modified roundabout, new pavement, and a paved trail connecting to Sullivan Lake Park from Central Avenue. Construction is tentatively scheduled for 2022.
37th Avenue Reconstruction: Central Avenue to Stinson Boulevard
The cities of Columbia Heights and Minneapolis have received funding to help support the complete reconstruction of 37th Avenue from Central Avenue to Stinson Boulevard. The future construction would include a new street section, utility replacement, sidewalk and/or trails and storm water. The addition of street lighting is also being evaluated. Construction is tentatively scheduled for 2023.
Central Avenue Safety Improvements Phase II: 43rd to 47th Avenues
This project would continue the safety improvements installed in the 2016 project from 47th to 51st Avenues. Work would include new LED street and pedestrian lighting, new sidewalks, new signage and minor right-of-way acquisition. Staff is pursuing funding to help support the estimated $1.7 million dollar project cost. There is currently no timeline for construction.
