Employment Districts City Planner Anderson presented the staff report. He stated that at the December 2019 EPB meeting there was continued discussion about potential amendments to the landscaping requirements for the Employment Districts (E-1, E-2, and E-3), which originated as a result of the Delta ModTech Landscape Plan. The EPB had reviewed what various peer communities had for landscaping requirements. Additionally, the EPB expressed a desire to explore what the results would be if the Canopy Cover Formula, which is applied to multi -family developments, were applied. Staff was directed to prepare exhibits to assist the EPB in understanding what the various Code requirements would look like. He reviewed the different models and examples of what is required in neighboring communities. Chairperson Valentine asked if it would be useful for the Board to outline goals. He stated that the Board could reinforce some of the strategic thought processes of staff. He commented that the ornamental trees and shrubs provide instant greenery, rather than awaiting the larger tree species to mature. He explained that diversity ensures immediate assistance with aesthetics. He agreed that the long-term projections should also be taken into account when landscaping, such as future expansions of a business. Board Member Hiatt stated that one goal is to create a healthy environment in the landscaping plan, to ensure the health and longevity of the trees and plants installed and in the overall environment. He commented that having diversity in the tree population helps prevent against damage that could occur from future tree diseases. He asked if there is a way to incorporate natural landscaping, which could help to reduce the amount of impervious in the calculation, similar to stormwater ponds. City Planner Anderson referenced the Great River Energy site in Elk River that is being decommissioned. He noted the natural landscaping work that occurred on that property and stated that it would be interesting to watch that site and see what happens without the active management that was occurring. Chairperson Valentine stated that although he likes the idea of natural landscaping, not every site would be ideal for that. He commented that there is also a lot of management that is required, which does not make it ideal for every site. Board Member Covart referenced the formula for the tree cover and asked if the different varieties would include more greenery and would mature more quickly to provide a variety in tree species. City Planner Anderson provided details on the characteristics of the different tree groups and stated that having some formula would ensure a variety of species and growth rates. Board Member Hiatt asked if there is a cost factor between the different species. City Planner Anderson stated that cost does vary depending on species and cost would be a factor in landscaping. He noted that there are also trends that cause certain trees to be selected more often. Environmental Policy Board / February 10, 2020 Page 2 of 4
