The Village would like to remind residents of the ongoing restoration of the 10.3 acre conservation area of the Stonebridge Subdivision (located along Green Bay Road).  The following information provides details about the planned restoration work and a general update regarding the subdivision project.

As part of the initial approval documents for the Stonebridge Subdivision the developer is required to completely restore a 10.3 acre conservation area at the eastern end of the site, which includes all of the wooded area extending east to west between Green Bay Road and the original estate house, and from the north property line of the site to the south property line. The conservation area also includes the original pond visible from Green Bay Road. 

In the spring of 2012, the current developer of the Stonebridge Project, The Roanoke Group ("TRG"), awarded a contract to Pizzo & Associates, an ecological restoration company from Leland, Illinois to perform the initial phase of the forest restoration work. The first phase of the work included the removal of all of the understory buckthorn and honeysuckle and other non-native plants and understory shrubs. The work will also include the removal of the majority of the fallen trees and the removal of trees from the perimeter of the conservation area determined by the Village's tree consultant, Urban Forest Management, to be hazardous or diseased.

During the week of February 18, 2013, The Roanoke Group will commence with the second phase of the conservation area forest work. Roanoke has hired Canopy Tree Specialists, a local tree company that will be working under the direction of Urban Forest Management to remove all of the diseased and undesirable tree species throughout the conservation area forest. The planned removal includes an estimated 220 existing ash trees, all of which either have or are expected to become infected with Emerald Ash Borer.

In late March 2015, the Village authorized TRG to start the third phase of the conservation area forest work. TRG hired Kinnucan, a local tree company that worked under the direction of Urban Forest Management to remove diseased and undesirable trees (non-native removal, thinning for increased sunlight, etc.) throughout the conservation area and to complete fertilization and trimming of trees.

In June 2015, the Village authorized TRG to continue some smaller scale conservation area forest work. TRG again hired Kinnucan who worked under the direction of Urban Forest Management to remove eight (8) hazardous trees within the conservation area and near the manor home. Kinnucan also began restoring the integrity of the forest floor by removing debris and replenishing the soils.

Following an assessment of the conservation area and work completed to date in early summer 2017, planning efforts by Kinnucan (in consultation with Urban Forest Management) commenced in earnest during the fall of 2017 regarding future planting and removal work. Planning efforts included (i) the establishment of a 100' x 100' grid management system in order to maximize future/current tree growth to their natural form, size, and health, and (ii) a review and reconsideration of tree species selection with a goal of increasing diversity.

During the spring of 2018, the Village authorized TRG to start the fourth phase of the conservation area forest work. TRG hired Kinnucan, Mariani Landscaping, Landscape Architect Paul Haden and Arborist Mark Duntemann - all under the direction of Urban Forest Management - to remove a total of 64 hazardous trees throughout the conservation area this calendar year and to develop plans to plant 100 certain canopy and understory trees. The first 30 trees, which are very large caliper canopy trees and exceed the minimum size requirements called out in the Forest Management Plan, are being planted over the next few weeks with more canopy and understory trees to be installed before October 30, 2018.

Removal of the diseased, invasive, and other undesirable species is necessary to reestablish a healthy oak/hickory forest. Currently, due to tree density and the significant number of invasive species, no oak seedlings and very few hickory seedlings have been found on the site by Urban Forest Management. Subsequent work requirements include the planting of 150 new trees of selected species, as well as forest floor native plantings, including such species as trillium, wild geranium, and may apples.

During this phase of the work the tree removal contractor will be permitted to work 7:00 a.m. to 6:00 p.m., Monday through Friday, and 9:00 a.m. to 5:00 p.m. on Saturdays. However, the operation of chain saws, chippers, heavy equipment, and any other type of tool or equipment, shall be limited from 8:00 a.m. to 5:00 p.m., Monday through Friday, and 9:00 a.m. to 5:00 p.m. on Saturdays. No burning of removed material will be permitted during this phase.

The Roanoke Group continues to rework the original development proposal which was presented to the Village's Joint Plan Commission and Zoning Board of Appeals (PCZBA) on November 28, 2012. At the current time it is estimated a revised development proposal, developed in consideration of comments received at the November 28th meeting, may be scheduled for a meeting of the PCZBA in the near future. Updates are available by clicking here.
