Old Business Parking Lot Subcommittee The subcommittee updated committee members on the progress made in their previous meetings. The subcommittee plans to review all of the recommended ordinance changes with the Arbor Committee at the January meeting and will be prepared to share the changes with city staff thereafter. Pollinator Garden Planning The Arbor Committee discussed the need to hire a landscape designer who is familiar with pollinator garden plantings. An example of similar project, which included a landscape plan, that was recently completed in the City of Shoreview was shared. If the pollinator garden is intended be a showcase for the city, committee members feel it is necessary to work with an expert in order to better determine the design and plant materials that will make up the garden. Corrow stated the city is open to that approach and will reach out to several design firms to establish a plan. Corrow also shared that a presentation to the Park Board will be moved to their January 18 meeting, allowing more time to develop a plan.  Since the piece of land provided to the Arbor Committee is over 17,000 square feet, the committee decided that a majority of the site can be covered in native prairie grasses and a few new tree plantings, while the actual pollinator garden will make up approximately 2,000 square feet, which is consistent with the size of the Shoreview garden. Two members of the Maple Grove Rotary Club attended the meeting and offered some insight on planning the pollinator garden. The Rotary also offered to help fund a significant portion of the project. New Business Buckthorn Eradication Group Members of the Maple Grove Rotary Club shared a sign that they intend to install at locations where the group has removed buckthorn in public areas. The sign will inform the public of their efforts in reducing the presence of buckthorn and is intended to recruit volunteers. Area Reports None Adjournment Motion Piket, second Henke to adjourn the meeting at 8:07 p.m. Vote all ayes. Motion carried. Respectfully submitted, Jesse Corrow, City Planner City of Maple Grove Arbor Committee  REQUEST FOR ARBOR COMMITTEE ACTION MEETING DATE: February 8, 2024 PREPARED BY: Jesse Corrow, City Planner AGENDA ITEM: Ed’ Buckthorn Proposal - agenda item 5 PREVIOUS ACTIONS: Ed’s Buckthorn Control was contracted to remove and treat invasive vegetation in the Forest Preservation area last year. The arbor committee is asked to review proposals to control buckthorn in the Forest Preservation Area and provide a recommendation to the City Council for approval. RECOMMENDED ARBOR COMMITTEE ACTION: Review the contract estimate provided Ed’s Buckthorn Control and decide if all of the treatment services are necessary for this year. Ed will try to attend the meeting to review the proposed treatment methods outlined in the estimate. If the Arbor Committee finds the proposal acceptable, they are asked to make the following motion: Motion to recommend the City Council authorize the expenditure of necessary funds to continue to control buckthorn and other invasive vegetation in the Forest Preservation Area, by use of the contract provided by Ed’s Buckthorn Control. COMMENTS: A description of each proposed service is provided in the estimate along with the associated cost. Maps of the treatment areas are also provided by Ed’s Buckthorn Control.

In 2024, we are shooting in the dark again for the budget, so please give us feedback if you want to do more or less work than I have outlined here. This proposal focuses on maintenance and restoration of the areas we cut in 2023, as well as maintaining areas cut before we were involved, before these areas get out of hand. Generally, we are staying in the same section near Vicksburg and pushing Southward. Please let us know if this is too much for one year and we will attempt to whittle it down, but everything proposed here is intended to protect previous investments and start the clock on the restoration timeline for introduction of native species. Any line item proposed for winter 2024 will be attempted this winter, (2023/2024) but is subject to snow timing and frozen ground for machine work. If we have another deep snow winter like last year, machine work would be done November/December 2024 instead (if the ground freezes enough), and follow-up spray treatments for 2024 machine cut areas would be pushed into 2025.

Through Arbor Commitee experience in reviewing landscape plans it is frequently noted needed details are missing to review plans and determine if they meet Ordinance requirements. O�en the designer does not include minimum informa�on to even complete a review. Sec. 36-831 (b) (1) The plans shall include in table form: Having this informa�on standardized makes it easier and more efficiently determine if all the requirements are being met.

The document itself is an established standard and is widely used and is updated periodically to maintain current best prac�ces. Addi�onally, our own experience with development in the city have shown that trees are not being properly protected. Sec. 36-831 (b) (6) Grade change/root cutting details of any existing trees. Exis�ng trees that are proposed to remain will have a higher survival rate if the impacts of grade changes (both adding soil or root cu�ng) in the vicinity of the tree are addressed. Mapping this informa�on out will ensure that impacts and mi�ga�on are accounted for. Typically, exis�ng trees which are planned to remain are large, valuable trees and worth addi�onal care to ensure their health. Sec. 36-831 (b) (10) Locations of all existing and proposed utilities.

Trees in containers shall be a minimum #25 Container (25 gallon) Trees in #25 containers provide more soil volume and it will be less likely for the roots to grow to the edge of the container and then begin circling which causes girdling roots.

Smaller trees adapt beter to their new environment than larger, older trees, and they will catch up in size quickly.” htps://mylearning.nps.gov/library-resources/tree-replacement-planning-plan�ng-and- establishment/ (Na�onal Park Service) "A large tree is much more costly and less likely to thrive," she said. "A smaller, younger tree will be more resilient and more vigorous." Younger trees recover more easily from the transplan�ng process and start to grow again more quickly. A larger, older tree will suffer more shock and o�en will take years to put on much new growth. In fact, studies have shown that a tree that is smaller when it is planted can usually outgrow a bigger tree in a decade. "It will catch up and pass the larger tree," Taylor said. htps://www.chicagotribune.com/lifestyles/home-and-garden/ct-sun-0709-garden-morton-20170705- story.html Sec. 36-831 (d) Credit for existing trees Trees which are infected with a disease such as Dutch Elm or Ash Trees infected with EAB are known to known to have a very shortened lifespan. Without interven�on to save the tree they should not be accepted as an exis�ng tree. Addi�onally, these trees become hazardous (britle) very quickly and can fall without warning. Sec. 36-831 (e) Parking Lot Design This verbiage from the exis�ng ordinance was simply moved to a new sec�on that focuses on overall design. Sec. 36-831 (e) (1) Snow storage areas shall be identified on the Landscape Plan We observed mul�ple instances of trees declining/dying or being severely damaged across the city due to snow storage and felt guidelines were needed to protect trees during winter months.

A few of the general requirements are: - Distribute landscaping throughout the site to so�en and screen parking lot edges, reinforce circula�on routes, create pleasant pedestrian condi�ons and maximize shade and stormwater benefits - Consolidate so� landscaped areas, par�cularly in larger parking lots, to enhance tree and plant material growing condi�ons htps://www.toronto.ca/city-government/planning-development/official-plan-guidelines/design-guidelines/greening-surface- parking-lots/ htps://www.dropbox.com/scl/fi/lrlf8tgust7pvd26e347v/Greening-Surface-Parking-Lot-Guidelines- RS.pdf?rlkey=mt2j34lhp98hxwqyh0cayeut6&dl=0 The City of Annaheim has language to help ensure vast expanses of parking areas are broken up by landscaped islands with trees. We combined requirements from Toronto and Annaheim to come up with language we felt best met the needs in Maple Grove htps://codelibrary.amlegal.com/codes/anaheim/latest/anaheim_ca/0-0-0-69845#JD_18.46.030 Sec. 36-831 (f) (1) All overstory trees must have a minimum (1000 CF. and 3’ depth) One of the most important design measures we take to promote strong tree growth is to provide an adequate volume of non- compacted, fer�le, organic soil in the tree root zone. So how much soil does a tree need to reach its growth poten�al? For the last 30 years or so, 1000 cubic feet has been used as a rule of thumb based on research done at Cornell University. The research asserted a need for 2 cubic feet of soil for every square foot of tree crown projec�on, which works out to roughly 1000 �3 for a tree with a 25-foot diameter crown. However, the 1,000 cubic feet doesn’t account for differences in water use (which the research addressed) and tree size. Trees in hoter, drier climates need more soil, as do larger tree species. A tree that needs 1000 cubic feet in New York might need 4000 cubic feet in Phoenix.

Too much mulch or mulch too close to the tree stem results in rot, insect damage, etc. Sec. 36-831 (n) “Protecting existing trees during construction” Proper protec�on of trees during construc�on is vitally important to their survival. Trees die slowly over mul�ple years and the effects of damage are not immediately visible. As such, detailed considera�ons and methods based on research are desired beyond the limited details currently in the ordinance. Sec. 36-831 (o) “Inspections” Jus�fica�on not really needed.
