2021 STREET REHABILITATION PROGRAM  (Map)
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, 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. 

The goal of the program is to do the right type of street rehabilitation at the right time to avoid the more expensive option of reconstruction.  Each street is evaluated using the following methods and an Overall Condition Index (OCI) is determined. 

  • The thickness of the existing pavement and underlying aggregate base has been documented.
  • An independent testing firm has determined the strength of the street and provided a visual condition rating.
  • A comprehensive visual condition street survey is conducted by the Engineering Department staff by measuring the type and quantity of each type of cracking in the pavement.
  • MnDOT also visually rates State Aid Streets every two years.

These results are used to determine the appropriate treatment to maximize the life of the street.  An OCI of 70 or greater suggests seal coat is the appropriate treatment.  An OCI between 69 and 55 reflects that the bituminous pavement is showing signs of significant deterioration and a mill and overlay is required to strengthen the pavement.  An OCI of less than 55 suggests the best course of action is to reconstruct the street, typically because both the pavement and the base under the pavement are failing.  The need for full or partial reconstruction is determined by the condition of the curb and gutter.

1.   ZONES 4B AND 5 - NW QUADRANT OF CITY  (Feasibility Study)  (Map)

The location and type of proposed construction work is listed below:

Zone 4B Street Rehabilitation

Partial Street Reconstruction
The entire depth of the pavement and underlying base will be ground together with a reclaiming machine.  This material will be stockpiled on-site.  The underlying soil will be removed and graded as needed to place 6” of reclaimed material and 4” of new bituminous pavement.   Existing concrete curb and gutter would be preserved except for sections with poor drainage or that are considered to be a hazard to the snowplows.   Pedestrian ramps will be reconstructed to meet current ADA standards.

  • 4th Street NE                           48th Avenue to 53rd Avenue                          
  • 5th Street NE                           48th Avenue to 49th Avenue                          
  • 5th Street NE                           51st Avenue to 53rd Avenue                          
  • 6th Street NE                           48th Avenue to 50th Avenue                          
  • 6th Street NE                           51st Avenue to 52nd Avenue  

Mill and Overlay
The top 1” to 2” of pavement surface will be removed by milling.  Depending on the thickness of the existing bituminous and cross-slope of the street, either a 6’ to 8’ strip along the curb and gutter or the entire width of the pavement will be milled.  A 1” to 2” bituminous overlay will be paved over the entire width of the street. Existing concrete curb and gutter would be preserved except for sections with poor drainage or that are considered to be a hazard to the snowplows.   Pedestrian ramps will be reconstructed to meet current ADA standards.

  • 7th Street NE                           48th Avenue to 52nd Avenue
  • Washington Street NE          48th Avenue to 51st Avenue              
  • Madison Street NE                 48th Avenue to 51st Avenue

Zone 5 Street Rehabilitation

Mill and Overlay
The top 1” to 2” of pavement surface will be removed by milling.  Depending on the thickness of the existing bituminous and cross-slope of the street, either a 6’ to 8’ strip along the curb and gutter or the entire width of the pavement will be milled.  A 1” to 2” bituminous overlay will be paved over the entire width of the street.  Existing concrete curb and gutter would be preserved except for sections with poor drainage or that are considered to be a hazard to the snowplows.   Pedestrian ramps will be reconstructed to meet current ADA standards.

  • 6th Street NE                           47th Avenue to 48th Avenue  
  • Washington Street NE          44th Avenue to 46th Avenue  

 2.   44THAVENUE NE FROM UNIVERSITY AVENUE TO JEFFERSON STREET (Feasibility Study)  (Map)

Mill and Overlay
The proposed construction would consist of milling off 3” of bituminous pavement across the entire street surface and paving a new 3” bituminous mat. Existing concrete curb and gutter would be preserved except for sections with poor drainage or that are considered to be a hazard to the snowplows.   Pedestrian ramps will be reconstructed to meet current ADA standards.

3.  2021 SEAL COAT PROGRAM, ZONE 3B – NE QUADRANT OF CITY  (Map)

Zone 3 was divided into two areas to provide CenterPoint Energy time to complete the gas service replacements in the NE quadrant of the City. 

Concrete curb and gutter repairs as well as crack sealing has been completed.

Public Works staff provides bituminous street repairs and patching throughout the Seal Coat project zone.  This includes cutting and removal of deficient segments of street section, milling of larger areas of deficient bituminous areas, and patching or paving with new bituminous.

A contractor constructs the seal coat with an application of emulsion by computer controlled mechanical sprayers immediately followed by spreading FA-2 or FA-2 modified granite or trap rock as a cover aggregate. The road surface is finished by rolling with a tire-based roller for proper aggregate penetration and distribution.

2021 WATER MAIN CONSTRUCTION PROGRAM  (Map)
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-1960s, 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.  In 2021 the following water main will be replaced. 

  • Buchanan Street NE, 37th Avenue to 39th Avenue
  • 39th Avenue NE, Buchanan Street to Johnson Street
  • Johnson Street NE, 37th Avenue to 39th Avenue

The construction will consist of setting up a temporary water service, removal of bituminous and concrete surfaces, replacement of water main, reconnection of water services and curb and gutter, pavement, driveway, and turf restoration.

2020 Construction Projects

1)       37th Avenue Street Rehabilitation and Trail Reconstruction
An 8-foot paved multi-use trail was constructed on the north side of 37th Avenue from 5th Street to Central Avenue. The work involved site grading, retaining wall construction, new pedestrian ramps, the construction of an 8-foot wide bituminous trail and restoration.

Following the completion of the trail, the City of Columbia Heights and the City of Minneapolis partnered 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 were 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 was removed, underlying soils were graded, gravel base was placed and a new concrete surface was poured.  

3)         2020 Water Main Replacement
Due to the number of water main breaks, the following water main segments were replaced in 2020: 

  • 39th Avenue, Johnson Street to Arthur Street
  • Arthur Street, 39th  Avenue to 40th Avenue
  • Stinson Boulevard at 43rd Avenue

The work involved setting up a temporary water service, removal of bituminous and concrete surfaces, replacement of water main, reconnection of water services and curb and gutter, pavement, driveway, and turf restoration.

4)         2020 Street Rehabilitation Program
A condition analysis was conducted on the streets in each zone. Based on the condition rating, the following streets were reconstructed:

            ZONE 4A

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

On 5th St, the work involved setting up temporary water service, removal of bituminous and concrete surfaces, replacement of water main, and reconnection of water services.  On both 5th and 6th Streets the remainder of bituminous and concrete surfaces were removed.  Construction included grading, new aggregate base, concrete curb and gutter, bituminous pavement, driveway aprons, concrete entrance walks, concrete pedestrian ramps, spot replacement of concrete walk and turf restoration.

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.  An existing sanitary sewer lift station interfered 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 combined both the boat launch reconstruction and the relocation and reconstruction of the lift station. The proposed work included 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.  

6)        Traffic Signal Replacement: Central Avenue at 41st Avenue (MnDOT project, resumed from 2019)
MnDOT completed the traffic signal replacement at this intersection. The work included 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").  

7)         2020 Seal Coat Program
Zone 3 was divided into two areas to provide CenterPoint Energy time to complete gas service replacements.  Bituminous streets in the northeast quadrant (Street Rehabilitation Zone 3) of the City were patched and seal coated in 2020.  The remainder of the streets are scheduled for 2021.

8)         Pump Station 3
The City of Columbia Heights performed rehabilitation to the piping, pumps, motors and valves inside of Pump Station 3 located on Ivanhoe Place.  Most mechanical components at the station were 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.  

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.
