Structured removal is the removal of blocks of infested ash trees throughout the city. The EAB Management Plan presumes that once trees are removed through this program the stumps will be treated, later removed, and a variety of new trees will be planted.

ALERT! MnDOT continues to remove ash trees along state roadways within the city, including 7th Street and Minnehaha Ave East.

2022 Structured Removal Schedule

This schedule refers to Structured Removal blocks, where there are concentrated groupings of ash trees. The scheduled removal of individual ash trees throughout the City in 2022 will have sites replanted as expeditiously as possible, however they may be subject to our regular district-wide stump grinding and replanting schedule.

  • Tree Removal (2022)

    • The removal of ash trees on Structured Removal blocks has been completed. The removal of individual ash trees in Districts 3, 5, 6, 7, and 14 has been completed. The removal of individual ash trees in all other districts has begun, and will continue throughout the year until complete. Please refer to the interactive web map for additional information on ash scheduled for removal this year.
    • Please remove all vehicles from streets where tree removals are set to begin - no parking signs will be posted several days prior to removal of the trees and serve as an indication that tree removals will begin soon.
  • Stump Removal (2022)
    • Stumps from Structured Removal blocks of ash trees removed in 2022 will be ground in 2022. Stumps from individual ash removed throughout the year may be subject to our regular district-wide stump grinding schedule. Permits for homeowners to grind stumps early on Structured Removal blocks of ash will not be approved*.
  • Planting (2023)
    • Replacement trees from Structured Removal blocks of ash trees removed in 2022 are tentatively scheduled to be planted in Spring of 2023.  Replacements for individual ash removed throughout the year may be subject to our regular district-wide planting schedule. Planting permits on Structured Removal blocks of ash will only be approved for homeowners after the stumps have been removed by the City*.

*The only exception to this would be for property owners who had trees removed from the side of their property, bound by a street and an alley. In these exceptions the removal of stumps and replanting of trees by the property owner would not impact the City's future work on the remainder of the street. All stumps adjacent to the applicant's property must be included in the permit application for grinding and replanting in order to receive approval. Please refer to the Boulevard Tree Permits page for more information.

2021 Structured Removal Schedule

This schedule refers to Structured Removal blocks, where there are concentrated groupings of ash trees.

  • Tree Removal (2021)

    • Structured Removal of ash trees in 2021 have been completed.
  • Stump Removal (2021-2022)

  • Planting (2022-2023)
    • Planting replacement trees at some of these sites is currently underway. Planting of additional sites will continue in the fall of 2022, with the remainder of unplanted sites projected to be planted in spring of 2023. Planting permits on Structured Removal blocks of ash will only be approved for homeowners after the stumps have been removed by the City*.
    • Grant funds awarded by the Minnesota Department of Natural Resources has enabled the City to partner with Tree Trust to plant replacement trees along Sherburne Avenue (from Western Avenue to Rice Street) and Van Buren Avenue (from Arundel Street to Western Avenue), which will be planted in the fall of 2022.

*The only exception to this would be for property owners who had trees removed from the side of their property, bound by a street and an alley.

What is Structured Removal of ash?

The City of Saint Paul has, since 2010, employed the "Structured Removal" of ash in order to strategically reduce the total percentage of ash trees on boulevards and in parks throughout Saint Paul.

How are trees selected for structured removal?

In the past, the focus for structured removal was on areas that were planted in a monoculture of ash trees. Ash trees that were declining from non-EAB related causes such as drought, salt injury, mechanical injury, and structural defects, were selected for structured removal. In general, ash trees become brittle and drop many branches while reaching maturity and are a common source of complaints from residents. 

Due to the continued spread of the infestation, and to the general infestation level city-wide, structured removal now encompasses all ash trees. Structured Removal blocks are identified during routine annual surveys and consider factors such as tree condition, density of ash populations on given blocks, and proximity to schools, recreation centers, churches, libraries, and parks.

Why are you removing live trees?

Once an ash tree becomes infested with EAB, it generally takes 3 to 5 years for the tree to die. By removing these trees before mortality occurs, the City is reducing the number of dead and potentially hazardous ash trees in the city. Also, the removal of these trees becomes much more dangerous when they are dead or nearly so. The safety of the citizens of Saint Paul as well as the crews maintaining the urban forest are a top priority.

Why not save the trees with insecticide treatments?

  • Treatment of public trees was employed as a means of slowing the population growth of EAB.
  • Insecticide treatments have been used on select public property ash trees since 2011.
  • No new ash trees are able to be added to the treatment program, and those treatments are being discontinued.
  • Trees that were last treated by the City in 2020 and 2021 have already received their final treatment.
  • Trees last treated in 2019 will receive one final City administered treatment in 2022.
  • All ash trees previously treated by the City will be on schedule for removal in 2023 or 2024.

Please note: this only applies to trees treated by the City and will not impact any public ash tree being treated on a regular interval by the adjacent property owner via the established permitting process.

 

If you have an ash tree adjacent to your property the City will reach out through the mail with further information. A copy of the mailed letter and the mailed postcard can be viewed by clicking the links below.
