Guests: Jeremy King, Denison University; Aidan Eells, Denison student; Jon Miller, Assistant Village Planner; Darren Willey, Village Services Dept.
Minutes of the November 14th meeting were approved.
The airspading estimate from McCullough’s is $5,854 for twenty trees uptown. Jeremy King reported that Denison had about fifty trees air-spaded on the east quad recently. Jon Miller said we can go ahead and send in a requisition if we only choose to do 2-3 trees, as has been suggested as a test to see if airspading will help these trees. January-March is the time of year that McCullough’s felt best to do this treatment. Dick Mortensen said that it would take about two leaf-outs before knowing if the treatment worked on those trees.
We had forty trees planted by Albyn’s this December, at a cost of $11,800. Tree species include: Black Maple, American Elm, Paperbark Maple, Honey Locust, European Hornbeam, Gingko, Shumard Oak, Norwegian Maple, Yellowwood, Cornelian Cherry Dogwood, Black Gum, Red Bud, Red Horsechestnut, and Sweet Gum.
Klauder has things in place for planting at Thornwood Crossing. Straw is on the ground now to prevent freezing. Jon and Debi Yost had prepared packets for us outlining Phase 1, now, at $4,980. Phase 2 will come later, to a projected total of $10,975. Commission members questioned the addition of arborvitae to the plans as this is known to attract deer. It was disappointing that ODOT will not allow the planting of Yellowwood trees, citing potential size as a concern.
Tree Cookie – Jon has emailed Wade (where the tree slice is now) and the Franklin Park Conservatory and is waiting to hear back from them on their advice for protecting the cookie from the elements.
Don Hostetter and Mollie Prasher made the December 1st deadline for our Tree City USA application.
Darren Willey reported that they will be wrapping up leaf pick-up in another week. This week the services department will be removing a tree on College St. at Burke Hall. There are several dead ash trees in Fanchion Lewis Park and another on Fern Hill to remove.
Jeremy King brought news of projects at Denison. There is some discussion over starting their own nursery, planting thirty-fifty saplings a year of more rare types.
Aidan Eells presented his research to us on the existing trees in the uptown area, six blocks of East and West Broadway, one block north and south on Main Street, and one block north and south on Prospect St. Aidan logged 184 trees and, using the GIS Collector App, entered data for street name, block number, estimated height, diameter, estimated health on a 5-point scale, yearly tree growth, species, made notes on the tree collar and exposed roots, the canopy and trunk, and any pertinent notes about the tree pit, lawn, etc. He also photographed each tree. Don Pheneger asked that we could have those also to compare to in the future.
Through a power point presentation, he shared a species layout pie graph and a tree distribution list. (Jon will send Aidan’s full report to us.) Aidan observed issues with mulch mounding, compaction, poor watering, including drainage issues caused by trapped water, salt and pollution. Options to consider include 1) preventing mounding, adding compost and vital nutrients, 2) re-digging a section of the tree pits and adding Silva cells and 3) completely re-digging the tree pits while also adding new soil including structured soil. Good structured soil consists of stone, clay loam, and good fresh soil.
Re-digging and redesigning the tree pits could allow for the trees to be planted lower than the surrounding sidewalks, allowing them to benefit more from rainwater run-off. Jon feels grants could be available for projects concerning erosion and storm water run-off. There are also grants available through the Arbor Day Foundation. Darren mentioned a solution the services department used in an area with compaction from trucks. They installed black plastic honeycomb-like structures and planted grass on top. This was much less expensive than Silva cells and has held up well so far.
It was mentioned again that some of these struggling trees in the business district may not have been planted and pruned correctly early on. Events during the lifetime of these trees, such as the extensive sidewalk work done years ago, may have compromised their success. Aidan observed some that appeared to have been planted too high, some too low.
We look forward to receiving Aidan’s full report and using the data he has collected on these trees.
The next meeting will be January 9, 2018 at 7:00 pm.
