Preservation and Planting of Trees Accompanying Road Construction in Oshkosh, WI A Tree Ordinance Proposal Matthew McTrusty George Stroschein Kevin Corbett Casimir Curney Table of Contents Executive Summary:2 Background/Problem Identification:3 Recommended Sample Ordinance:5 Stakeholders: 5 Bill Sturm: Urban Forester - Oshkosh, WI 6 Dennis Fermenich: Urban Forester - Greenfield, WI 8 Dan Trass: Ranger Services 9 Shelly Reinke: Greater Oshkosh Healthy Neighborhoods, Inc.10 Shirley Mattox: Jackson Street Neighborhood Association 11 Anonymous Homeowner 12 Kathy Webb: River East Neighborhood Association 13 Donn Lord: Winnebago Apartment Association 15 Benchmarking:16 Greenfield, WI 16 Burlington, WI 18 Appleton, WI 19 Eau Claire, WI 20 La Crosse, WI 21 Costs:22 Barriers:24 Significance for Sustainability:25 Mitigation of Diseases/Invasive Pests 25 Air Quality 28 Stormwater Management 29 Aesthetics 30 Summary/Conclusion 31 Citations 32 Other Wisconsin City Ordinances 34 Appleton Ordinance 34 La Crosse Ordinance 43 Eau Claire Ordinance 47 1 Executive Summary: The purpose of this document is to propose that the city of Oshkosh adopt an ordinance that requires the planting of terrace trees along city streets which are reconstructed or to be constructed in the future. Many of the streets in Oshkosh are scheduled to undergo reconstruction in the near future and a tree planting ordinance would greatly improve the city’s urban forest and tree cover in areas which currently may not have an abundance of trees or canopy cover. This ordinance would help improve aesthetics, erosion, runoff issues, canopy cover, air quality, wildlife habitat, and much more, while at the same time improving the city’s standing on the “Sustainability Strategies Scoresheet” regarding a tree preservation ordinance. A terrace tree ordinance would also be in accordance with Oshkosh’s urban forestry vision statement found on the city of Oshkosh’s website which states, “The Forestry Division’s goals are to establish maximum tree cover; to maintain the trees in a healthy condition in order to maximize benefits and minimize hazard, and to establish and maintain an optimal level of age and species diversity” (City of Oshkosh). The benefits for street trees are outstanding, and the ecosystem services that they provide will result in long term returns on investments. Although the city of Oshkosh currently strives to plant terrace trees following road construction activities, making it a required action would be a simple policy or addendum to the city’s current tree policy. Based on information and interviews from various stakeholders, there is very little opposition for such an ordinance. The main forms of opposition stemmed from issues that concern funding of tree projects. However, there is strong evidence that tree planting is a very marginal cost compared to road construction activities, and Greenfield’s urban forester Dennis Fermenich stated that tree planting costs less than .5% of any road construction project. Many other cities in the state of Wisconsin with comparable population sizes have added similar tree policies that are functioning extremely well and backed by strong support from residents of the community. Oshkosh is already an extremely ‘tree friendly’ city and is recognized as a member of Tree City USA, and UW Oshkosh is recognized as a member of Tree Campus USA. Oshkosh will continue to take a leadership stance on sustainability if this ordinance is adopted. Urban forester Bill Sturm stated that this is the perfect time to add a terrace tree planting policy, addendum, or ordinance due to the fact that many of the streets in Oshkosh are scheduled for reconstruction in the near future. This ordinance would provide Sturm with the funding necessary to plant diverse tree species and improve the health of the urban forest. With diseases such as elm disease and invasive pests like the emerald ash borer, maintaining a healthy and diverse urban forest will be imperative for the future. If this ordinance is adopted, Sturm and his team of certified arborists will oversee the planting and maintenance of terrace trees, all while working with homeowners and other members of the community to ensure proper tree placement. In depth details of the multifaceted topics pertaining to the terrace tree ordinance can be found within this document, along with sample ordinances from other cities. 2 Background/Problem Identification: Currently, there is no tree related ordinance that would apply to tree planting following new road construction or reconstruction. However, the city is considered extremely ‘tree friendly.’ Oshkosh was one of the first cities to be recognized as a member of Tree City USA in Wisconsin, and also the University of Wisconsin Oshkosh is part of Tree Campus USA, both of which are nationwide programs dedicated to the management and expansion of public trees. The city currently does not have a canopy cover goal, and is sitting at a relatively low city-wide canopy cover of only 18%. Bill Sturm, Oshkosh’s city forester, explained that there were weather circumstances that previously decimated Oshkosh’s tree population. In 2001, an extremely severe storm swept through central Wisconsin costing the city a loss of over 8,000 trees. Many of the trees have been re-planted, however the re-planted trees are too immature to account for a significant percentage of canopy cover. When looking at numbers alone, the data gives the illusion that the city of Oshkosh may have an extremely low number of trees or is not concerned with removal of large and mature trees, which Bill Sturm explained is not the case. The city was presented with the Wisconsin Urban Forestry Council’s 2011 Award for Project Partnership in recognition for the Taking Root Fund Initiative. The Taking Root Fund is a special project fund of the Oshkosh Area Community Foundation that focuses on improving the health and beauty of the city through the planting of trees. The initial fundraising goal was met at $500,000 and the first phase of the project included planting 1,000 trees along city streets and public park spaces. Fortunately, there is still money set aside and invested from the Taking Root Fund which keeps generating revenue and can be used for future tree projects. The city also 3 offers the community a resident based tree planting program known as the ReLeaf Oshkosh Terrace Tree Program. Neighborhood members can decide where they would like to plant trees and trees are sold to them at wholesale cost for about $50 to $60 per tree. The trees are then planted and maintained by the city of Oshkosh Forestry Division. This program focuses on community involvement and participation to enrich the city’s landscape. Although there are programs in place concerning trees within the city of Oshkosh, the city could still use a significant improvement on canopy cover, tree diversity, and tree funding. Given that many of Oshkosh’s streets will be reconstructed in the following years, this is the perfect opportunity to adopt an ordinance that will improve the city’s urban forest. Some community members may initially be unsupportive of a terrace tree planting ordinance due to maintenance issues with falling leaves or the thought that trees may block views from residential units. If such an ordinance is adopted, working with neighborhoods and members of the community will be imperative in order to place trees in areas where there will be minimal backlash. Another issue concerns funding, which may have to come from taxpayers or community members who live on reconstructed streets. However, Dennis Fermenich, the urban forester for the city of Greenfield, Wisconsin stated that tree planting costs less than .5% of total road reconstruction costs and that the city of Greenfield has $.50 per capita allocated to tree planting which covers the majority of the costs. Perhaps the city of Oshkosh could adopt a funding initiative similar to that of the city of Greenfield to cover the costs of this ordinance. The right steps are being taken to improve Oshkosh’s urban forest, however, a healthier urban forest will be achieved only if disease is kept at bay and trees are planted and maintained properly. Emerald ash borer is an issue that the city must address. Although the city treats ash 4 trees and other trees that are infected with disease or invasive pests, an increase in tree diversity is imperative to increase genetic variation. Norway maple is the most abundant tree species and accounts for 24% of the city’s trees, with crabapple species coming in second at 22%, and ash trees third at 9%. With the adoption of a tree planting ordinance, different species could be considered when planting new trees along reconstructed roads, which would further increase tree diversity and lower the chances of widespread disease and tree mortality due to invasive pests. Having a multitude of different tree species along the city's streets also improves wildlife habitat. By providing animals with a diverse tree population the city would be able to support a larger and more diverse number of wildlife species. Recommended Sample Ordinance: Urban forester Bill Sturm urged us not to prepare a sample ordinance, stating that Oshkosh’s current tree ordinance was just rewritten and it would be easier to make the proposed terrace tree ordinance a policy or an addendum to the recently revised ordinance. The goal of this document is that the city require the planting of terrace trees following road construction activities and adopt either a policy, addendum, or separate ordinance that addresses this issue. This document will refer to the issue as an ordinance rather than a policy or addendum to a current ordinance. Stakeholders: During our research for a new tree planting ordinance we identified various stakeholders who would be affected either directly or indirectly by the proposed ordinance. We talked with Oshkosh’s urban forester Bill Sturm and urban forestry experts from other cities based on their 5 experience and potential to provide beneficial knowledge concerning the ordinance. We also talked to members of the local community for their perspectives, local knowledge, and potential to have an influence on a tree planting ordinance. For this we interviewed homeowners, landlords, and active citizens. One stakeholder that we tried to get in contact with was Public Works Director James Rabe, but unfortunately we were unable to reach him. Bill Sturm: Urban Forester - Oshkosh, WI Bill Sturm, the city of Oshkosh’s urban forester, is a key stakeholder concerning our tree planting ordinance. He works with trees on publicly owned land, primarily including park and terrace trees. He is not permitted to go onto private land parcels to plant or remove trees unless the tree is undeniably going to fall into a right of way. Unfortunately, this can be a problem for the city because many trees are currently disease ridden on private parcels owned by homeowners who are unwilling to pay for treatment. This is resulting in the spread of diseases to publicly owned trees. However, Sturm and his team are exclusively comprised of certified arborists. Together they are able to quickly identify and effectively treat diseased trees on city property. A few years ago, Sturm worked with the Department of Natural Resources using the software system “i-Tree” which utilizes a geographic information system (GIS) platform to create a detailed city-wide map identifying each significant city owned tree. Documentation of these trees includes information related to the species, size, and health condition of each tree. This puts both Sturm and his team in an extremely good position when it comes to monitoring trees and knowing which trees may need particular attention or treatment. Bill Sturm holds a very positive outlook for trees within the city of Oshkosh, and explained to us that they are taking a number of steps to improve tree numbers and canopy cover. 6 The Oshkosh Forestry Division purchases most of their trees from Ranger Services out of Appleton, which has a two year warranty on any tree and will replace trees free of charge if they happen to perish. When Sturm first started, he was only allocated $3,000 a year to replant city trees. With programs he helped with, such as the Taking Root Fund, he has been able to oversee the planting of over 3,000 new terrace and park trees. There is still money set aside and invested from the Taking Root Fund to keep generating funds for future tree projects. When we brought up the idea of an actual tree preservation ordinance, he seemed more concerned than enthusiastic and urged us to re-think our approach. Sturm explained that a tree preservation ordinance may actually hurt his efforts to maintain and expand a healthy urban forest. Upon asking why, he gave us the example of Menasha, which has a preservation ordinance in place to prevent the removal of mature trees. When one of Menasha’s trees become sick, or has a disease that may rapidly spread to other trees, the urban forester and tree team of Menasha have an extremely hard time getting the authorization to remove that certain problematic tree and must jump through hoops to manage these trees, which can take a very long time. Instead of a preservation ordinance, Sturm leaned towards a tree planting ordinance that would allow him to plant terrace trees after street repair. He explained that the future plans for the city of Oshkosh include extensive street repair and reconstruction. He also explained that the most effective thing we could do is try to get an ordinance passed that would give him and his team the authority and funding to plant terrace trees along the freshly reconstructed roads. Currently, Sturm needs approval of all neighboring houses to plant new trees along roads, and says that one person who does not want trees is common because they believe it will block their 7 view or become an inconvenience when leaves fall, for mowing, or for other reasons. A road reconstruction planting ordinance could eliminate the hardships he and his team currently face when trying to plant terrace trees. Dennis Fermenich: Urban Forester - Greenfield, WI We also interviewed Dennis Fermenich as an expert stakeholder who has been a certified Wisconsin arborist for over 45 years and the urban forester for the city of Greenfield, Wisconsin for the past 22 years. Fermenich is extremely enthusiastic about Greenfield’s tree preservation program, his efforts to improve the city’s urban forest, and the possibility of creating a tree related ordinance for the city of Oshkosh. Like Bill Sturm, Fermenich only works with trees on city-owned land, and also utilizes a city-wide GIS tree mapping system. He explained that the biggest opposition he came across concerning tree preservation and planting had stemmed from the DPW director, city engineers, and city inspection departments. These problems have since been mitigated and now the varying members work positively and effectively to continue improving tree preservation efforts. Fermenich is dedicated to planting diverse and disease resistant tree species. He and his team also treat and prune problematic trees in the same manner as Bill Sturm’s team. Dennis Fermenich works fervently to acquire a number of state provided urban forestry grants. He recently received $118,000 in grants, explaining the most significant being the “Sweetwater Grant” which provided him funding to plant trees along tributaries which run into Lake Michigan, helping to alleviate runoff and erosion issues. Fermenich stated that the community has also become extremely involved with tree preservation efforts and that one of the 8 biggest city-wide events is the community Arbor Day plantings. During this yearly event, businesses and community members come together to plant trees in parks, along roads, on school grounds, or in other areas where the community sees fit. Fermenich reiterated that the residents of Greenfield have a sense of community like he has never seen before. He also stated that the momentum from their positivity helps to keep tree efforts moving throughout the city and enhances his ability to work towards a greener, healthier, and happier community. Dan Traas: Ranger Services - Appleton, WI Expert stakeholder Dan Traas is the founder of Ranger Services, Inc. out of Appleton, WI. As a consultant, Traas and his staff assist construction processes in pre-development areas and evaluate in what ways a local ecosystem will be affected by construction. Ranger Services supplies trees to the city of Oshkosh and provides replacements at no charge if the trees perish. Traas has 27 years of experience as a certified arborist and has become a member of the International Society of Arboriculture. When compared to the other major development companies in the Fox Valley area, Ranger Services has been able to continually shift their development methods to include more productive approaches to urban forestry. Traas is motivated by biodiversity, tree resilience, and holistic landscaping. He recommends that contractors make the tree a part of their site and not merely just as an expendable feature. Traas understands the benefits that higher tree diversity and increased canopy cover provide. The main way the city of Oshkosh can benefit from Dan Traas is as a reliable supplier of quality trees. Traas and his certified team also provide training and consultation to cities, developers, and schools. Traas has prior experience in helping draft tree ordinances and would be 9 helpful in developing maintenance and management plans that include the replacement, pruning, and trimming of street trees. Shelly Reinke: Greater Oshkosh Healthy Neighborhoods, Inc. Primary stakeholder Shelly Reinke works and lives in the city of Oshkosh. Reinke works for Greater Oshkosh Healthy Neighborhoods Inc., an organization dedicated to neighborhood development. Her perception of the tree planting ordinance was a positive one and Reinke stated that she would personally support it. Reinke acknowledged the many benefits that trees provide. She also mentioned that the ordinance may receive opposition from some people because trees require maintenance and people may not want to rake leaves or pick up the branches that fall off into their yards. Reinke suggested that the ordinance be crafted in a way that holds the city responsible for the maintenance for at least the first year. However she was unaware that city forester Bill Sturm and his team are responsible for maintaining all trees on city property. Unless someone calls and complains about a tree, Bill Sturm and his team have a hard time getting to all of the city’s trees every year. This could be solved by increased funding which would allow Bill Sturm to hire more certified arborists to adequately maintain all of the trees in the city every year. Reinke also stated that the ordinance would receive opposition from adding additional tax assessments because people are generally against higher taxes. She has a perspective of someone who works to build a sense of community and neighborhood improvement. The goal of Reinke’s work is to make the city a better place to live overall, but one way that Greater Oshkosh Healthy Neighborhoods Inc. does this is through aesthetics. They are motivated to try and beautify the city wherever possible, an obvious result that would come from a tree planting ordinance. 10 Having this positive feedback on the issue will help aid the city of Oshkosh in its decision to adopt a tree planting ordinance because Shelly Reinke is a homeowner who would be directly affected by our ordinance. She makes the assumption that this is purely for aesthetic appeal, however this ordinance would also further the city's sustainability goals. Shirley Mattox: Jackson Street Neighborhood Association Shirley Mattox is a primary stakeholder because she is a ‘Resident Leader’ for the Jackson Street Neighborhood under the Oshkosh Healthy Neighborhood Alliance. Mattox also serves on the Wisconsin Urban Forestry Council. She was supportive of the proposed ordinance and acknowledged the connections between sustainability and urban trees. As a citizen of Oshkosh and a formal member of the Oshkosh City Council, Mattox helped construct an ordinance similar to the one proposed, however it was not implemented. Her work on this proposed ordinance reflects her knowledge as well as commitment to the issue. Mattox explained that the Urban Forestry Council has awarded grants to Oshkosh Neighborhood Associations in the past for urban tree planting and that the levels of turnout reflect interest and support from the public. Besides a sense of community and added aesthetic values, Mattox also believes terrace trees contribute to safety as they create a barricade between the sidewalk on busier streets that may be accident prone. This is most significant for streets that are widened which leaves homeowners to face increased traffic levels and the possibility of traffic related accidents. Mattox envisioned the ordinance to be funded by an additional construction assessment for home or business owners after road construction takes place on the street in front of the property. 11 Because these assessments are often thousands of dollars, an additional tree at the wholesale cost of $50 to $60 dollars should be insignificant. Mattox believes that tree planting after road construction should be a societal norm, and that the city of Oshkosh would benefit by adopting this ordinance. A concern Mattox associated with costs is selecting a quality tree provider service, versus just awarding the business to the lowest bidder. Local arborists like Dan Traas will better understand local ecosystems and be the most qualified to work in the region. Giving business to distant or unreliable tree suppliers might result in steeper future costs if the job is not done properly. Anonymous Homeowner A primary stakeholder interviewed from the Millers Bay neighborhood would be directly affected by the proposed ordinance. The homeowner did not want to be identified in our project specifically, so they will be referred to as an anonymous homeowner from the Millers Bay neighborhood. This person stated that they were supportive of the new tree planting ordinance and also acknowledged the importance that trees have for ecosystem services. However, the homeowner stated that there is potential for opposition coming from their neighbors that have lake view property because new terrace trees could potentially obstruct their lake view. The homeowner never stated this directly, but gave the impression that their neighbors believed that a tree blocking their lake view would potentially lower property values. This could be combated by having Bill Sturm work with the homeowners within the community to plant trees in between their houses in areas which would not obstruct lake views. 12 This person also stated that opposition would come from adding more to people's taxes, but the homeowner thought that adding a small tax was a good solution to the funding problem. The homeowner also stated that if there was more educational opportunities provided which pertained to the benefits of trees, more people would be supportive of the ordinance. The homeowner expressed that a guarantee on the new trees would be a nice way to reassure homeowners, because then the city could guarantee that if anything ever happened to the tree it would be replaced at no cost to the homeowner. This homeowner has a perspective on this issue that focuses more on neighborhood aesthetics and is motivated to make their neighborhood look nicer by increasing curb appeal. Their perspective could contribute to this ordinance because as a homeowner they would be one of the people that is most affected by this new ordinance. Receiving their approval of the ordinance speaks volumes to the city of Oshkosh. Having homeowners on board with the proposed ordinance will be critical in moving the terrace tree planting ordinance forward. Kathy Webb: River East Neighborhood Association Primary stakeholder Kathy Webb is a local homeowner and member of the River East Neighborhood Association. Webb is directly affected by the proposed tree planting ordinance because her Otter street neighborhood recently went through street reconstruction projects. The city is going to finish reconstructing the rest of her street and other streets located within the neighborhood next year. Webb stated that she was in support of the proposed tree planting ordinance, but her motivation, like the other homeowners that were interviewed, was primarily to 13 improve neighborhood aesthetics. Even though Webb acknowledged the environmental benefits that trees provide, she was more interested in trees for their aesthetic value. Webb also stated that not many people would be supportive of the added assessment onto the construction costs, because construction projects are already an economic burden, and she did not know how some of her neighbors would pay for the existing construction costs. Webb thought that a city-wide tax was a great idea so that the cost for planting and maintaining of trees would be dispersed throughout the residents of the city. This tax could also be problematic because, as stated before, it is hard to get support anytime a tax increase is proposed. Webb also stated that if there were enough funds, a guarantee from the city to replace trees at no cost to the homeowner would be a beneficial addition to this ordinance. Webb expressed that she knew Bill Sturm and his team were busy and could not maintain every tree in the city. Therefore she suggested that the River East Neighborhood Association would distribute pamphlets encouraging homeowners to help water and take care of their newly planted trees. Kathy Webb also thought an essential addition to our ordinance would include Bill Sturm working with the community to decide what species of trees would be planted and where those trees would be located. This would give the homeowners some input when it came to planting the new trees. Again, Webb’s motivation, like the other homeowners or neighborhood associations that were interviewed, are not primarily focused on the ecosystem services that new trees would provide, but rather the curb appeal and aesthetic benefits. Regardless of her motivations, having someone from a prominent and active neighborhood association on board with the tree planting ordinance proposal will help the city of Oshkosh to better make their 14 decision based on what actual homeowners in the area want to see out of this proposed tree planting ordinance. Donn Lord: Winnebago Apartment Association Donn Lord, the president of the Winnebago Apartment Association, was identified as a primary stakeholder. Landlords who own multiple properties would be affected disproportionately by this ordinance because reconstruction costs can occur more than the one time, unlike what a typical homeowner would experience. Given the fact that landlords have tenants, there is less incentive for taking on optional costs such as those for tree planting due to the impermanence of tenants. However, as a landlord, Lord has taken on the costs of planting trees for one of his properties and said he was in support of an ordinance that would result in trees being planted post road construction. Lord acknowledged post road construction as an optimal time for tree planting because existing infrastructure has already been identified, as opposed to when he planted his own trees and had to identify where cable lines and other infrastructure existed. Due to the fact that people who want to plant terrace trees currently require approval, the proposed ordinance would reduce instances where single inspections would need to be made. Lord also mentioned that as a property owner he has witnessed tax assessment bills for road construction projects rise immensely over the last five years, and adding trees to the assessment would be too small of a cost to warrant opposition. Minimal cost and improved efficiency leads Lord to believe that this proposed ordinance would, “just make sense.” 15 Benchmarking: Our team researched what other cities in the state of Wisconsin are doing to improve urban forestry. Some of the cities we looked at included Greenfield, Burlington, Appleton, La Crosse, and Eau Claire. Many of these cities have urban forests with the same tree species as those found in the city of Oshkosh, and face similar issues concerning tree funding, disease, and maintenance. These cities are all in the state of Wisconsin and three of them have a population size comparable to Oshkosh. By analyzing what these cities are doing to improve and maintain their urban forests, we are better able to understand the multifaceted issues concerning Oshkosh’s urban forest and the possibility of a future tree planting ordinance. Aspects we looked for in these benchmarking cities were: existing ordinances in place, whether these ordinances are successful or not, how the costs of tree planting and maintenance are assessed, and how these ordinances have benefited the city overall. Greenfield, WI Although the city of Greenfield has a legitimate tree preservation ordinance in place, urban forester Dennis Fermenich stated one of the most important aspects of their tree ordinance was put in place 20 years ago. The addendum gave Fermenich the authority to replant trees along any of the city’s reconstructed roads. This addendum is very similar to what Bill Sturm suggested to propose for the city of Oshkosh. Fermenich elaborated on the details, and he happily exclaimed that he is authorized to plant one tree every 50 feet along reconstructed roads. When he is unable to plant a tree on certain roads due to imposing infrastructure or other circumstances, he can plant the allocated tree in other parts of the city where he sees fit, 16 primarily within the city’s parks. He explained that tree planting costs less than .5% of any road reconstruction project, and that his ability to plant trees along reconstructed roads has greatly improved the city’s tree numbers, diversity, and canopy cover. Funding for tree related projects in the city of Greenfield comes from a variety of sources. Fermenich explained that Greenfield’s tree commission is allocated $4,000 a year for tree planting (similar to Oshkosh’s initial budget of $3,000 per year) and that additional funding of $.50 per capita is put towards tree efforts. Fermenich also applies for state grants that are used to purchase and maintain trees. Similar to Oshkosh, the city of Greenfield has all significant trees mapped out using a GIS mapping system. This helps to keep an accurate and up-to-date record of which trees need maintenance, are currently diseased, or may pose problems in the future. Trained Department of Public Works members along with Fermenich are responsible for treating diseased trees. Over 500 of the city’s ash trees are currently undergoing treatment since emerald ash borer was identified in the city. Greenfield does not have a formal forestry department but instead uses a ‘working foreman system’ sending out pruning crews or other employees to safely remove and maintain trees. Fermenich is working specifically on tree diversity to avoid future widespread disease and says that the majority of the city’s trees are comprised of maple species, similar to Oshkosh. Future goals for the city include planting many different species with a specific species to not exceed more than 10% of the total tree cover in the city. Fermenich pointed out that tree preservation and planting of trees along roads has improved runoff issues, groundwater, aesthetics, CO2 reduction, and much more, but has also strongly bonded the community with city wide events dedicated to trees. 17 Burlington, WI Burlington, WI is currently undergoing a major restructuring of its urban forest. The emerald ash borer beetle is devastating the city’s population of nearly 800 ash trees. Although the city treats the infected trees, 63 ash trees were removed last year, 67 so far this year, and 50-60 more are planned to be removed this winter, resulting in a declining urban forest. On average the city plants 30-50 new trees each year along city streets and in the parks. With an average annual funding of $20,000 to $30,000 allocated to planting new trees and the labor associated with it, the city is struggling to maintain a healthy urban forest due to the costs associated with treatment and removal of the currently infected trees. Burlington is also expecting to spend approximately $1.5 million on flood cleanup costs, and replacing both the city hall and public library after the devastating flood that swept the city in August, 2017. Given the financial burdens facing the city, the City Council fears that there will be little available funding allocated to trees in the near future. Department of Public Works employee, Aaron Degrave, stated that the city is looking into alternative funding and that planting diverse tree species is imperative for the future. Although there are 79 different tree species in the city, ash trees are the second most common, after maple tree species, which comprise 48% of the city’s urban forest. To avoid future chances of widespread disease or invasive pests, the city will be planting redbuds, oaks, lindens, and other species to increase tree diversity. 18 Appleton, WI The city of Appleton’s street trees are planted after new street construction and street reconstruction projects during the planting season. Trees are also planted on request and as replacement for trees that are removed if space allows. Species selection is based on the site and its limitations. A wide variety of species are available for planting. The planting of new street trees, and street reconstruction, are both done on a block by block basis with one species on each block. Appletons public trees are governed under Chapter 21 of municipal codes, specifically Article II Public Trees and Shrubs. This article was recently restructured, therefore city forester Mike Michlig did not have a large enough sample size to provide relevant data on how the new ordinance is doing. Property owners and donors work with Michlig to choose the type of tree and a price range that works for them. Tree planting is site specific and each location must be assessed for proper species selection. The actual cost of the trees are assessed as part of the construction cost and based upon the amount of frontage footage the specific lot has. The property owner is only assessed for the cost of the trees once. All trees carry a full guarantee unless damaged or neglected by the homeowner. In the case of damaged trees, the homeowner would likely be responsible for the cost of replacement if they could not identify the responsible party. Like Oshkosh, the city of Appleton is also designated as a member of Tree City, USA. Also, all trees on public property are governed by the Public Works Department in Appleton. The city of Appleton’s street trees have produced an estimated 300 percent return on investment according to the Wisconsin DNR's work with the i-Tree software (i-tree, Appleton). Appleton receives 19 $3.31 million annually in benefits from their street trees according to the DNR (i-tree, Appleton). They receive $1.09 million in benefits related to stormwater management, $1 million from increased property values, $935,109 in energy savings, $157,511 in air quality improvements, and $125,452 in CO2 reduction (i-tree, Appleton). This shows that not only are street trees beneficial concerning aesthetics, but that they also provide ecosystem services that reduce the load on the city's infrastructure and inevitably save the city money. Eau Claire, WI The city of Eau Claire currently has two major street tree ordinances in place. One ordinance incorporates tree planting into public improvement projects, similar to the ordinance being proposed for Oshkosh, and the other ordinance involves a rebate program. Traditionally under public improvement projects, properties residing within the project area are eligible for up to two street trees, but this has recently changed. According to Eau Claire Forestry Supervisor Matthew Staudenmaier, the ordinance has shifted to a program of, “intentional diversification, with placement of the right tree in the right place being the cardinal rule.” This is important because instead of planting two trees per property regardless of the space, the ordinance now pays extra attention to each location, and tries to provide the tree species that will fit best. Factors such as power lines and terrace width are focused on rather than just planting a tree because construction occured. Overall, this is supposed to contribute to long term urban forest diversity as the trees planted are the best fit for that location, and have a better chance of long-term survival. However, it is important to note that despite this shift in policy, terrace trees are still planted in the city of Eau Claire after road construction, but the cost for trees is incorporated into the cost of the actual construction project. 20 The other tree ordinance that was implemented in the city of Eau Claire is the rebate program for terrace tree planting. Under this program, residents who wish to plant trees can apply for a potential rebate for those trees. Residents are also eligible for up to two trees per land parcel each year. Inspections are done by the city forester before the tree is planted and must meet all requirements laid out by the city. There are a total of 300 rebates given out on an annual basis. La Crosse, WI The City of La Crosse is another city that is comparable to Oshkosh because it has roughly the same population. La Crosse is also a certified Tree City, USA. They have approximately 20,000 urban trees flourishing in the city's parks and boulevards. La Crosse is recognized as a Bird City, which promotes urban tree habitat creation and protection. La Crosse’s forestry department is located within the Parks and Recreation Department. Their public trees are managed by the Director of Parks and Recreation, Steve Carlyon, and governed under Chapter 34, Article V. Trees on Public Property. However, much of the responsibility for managing these trees is delegated to the Parks and Forestry supervisor Dan Trussoni who is in charge of overseeing the management of the city’s trees. Dan Trussoni stated that La Crosse’s ordinance was reconstructed recently so they really haven’t had any issues with it yet. He also stated that the fees for the planting and maintenance of these public trees are assessed to the specific plot of land where the trees are being planted or maintained. These fees are then collected as any other special tax would be collected by the city. La Crosse’s street trees have 21 provided the city with many benefits including an increase in aesthetics, improved stormwater management, energy savings, improved air quality, and improved wildlife habitat. Costs: The costs associated with this new tree planting ordinance could be assessed in a number of different ways. There are two proposed options that would work well and that could potentially be adopted by the city of Oshkosh. The first option is to create an additional small tax that is city-wide to help pay for not only the planting of the trees, but the maintenance as well. The majority of stakeholders living in Oshkosh expressed that the maintenance of terrace trees may be the main form of opposition to the newly proposed ordinance. This city-wide tax would be a small amount collected annually from property owners in Oshkosh. This amount would be dependant on what is necessary concerning the tree planting and maintenance activities. The homeowners that were interviewed seemed to like the idea of a small additional tax, because they thought that this would be a small enough amount that everyone would have the ability to pay it. Also, this tax distributes the cost of the trees throughout everyone in the city, not just the homeowner. This form of assessing the costs for the trees would not marginalize poor neighborhoods because they would share the costs and benefits of paying for the new street trees with the other residents throughout the city. This helps build a sense of community and the city of Oshkosh should look at how lower income communities would be affected by whatever cost assessment option they decide. The second option is an additional assessment added onto the construction costs specifically for the homeowner who would be receiving new trees in front of their property. This is also a good option because the amount of the increase would be insignificant when compared 22 to the total cost of construction. This is Bill Sturm’s prefered method of assessing the cost of tree planting because the homeowners are already being assessed for the construction costs. However, some of the homeowners that were interviewed said that this was not a great idea because they stated the cost of having their street redone was already putting a heavy financial burden on the residents of that street. If the city decided to go this route, the residents of the specific street being reconstructed would be paying for the cost of the trees in front of their property. This would not distribute the cost evenly between everyone in the city, yet every resident would be receiving either direct or indirect benefits from the new trees. This ordinance is geared to give Bill Sturm and his team of certified arborists the best tools possible to further the City of Oshkosh's Sustainability Plan. This means the possibility of a larger staff and a larger budget to help them successfully plant and manage all public trees within the city of Oshkosh. It has already been noted by the Wisconsin DNR through the use of the i-Tree software that Oshkosh’s street trees represent roughly a 300% return on investment over their lifetime (i-tree, Oshkosh). Annually Oshkosh already receives $335,268 in total benefits from the street trees (i-tree, Oshkosh). This is broken down into $109,762 from increased property value, $103,138 from energy savings, $92,722 from stormwater management, $16,332 from improved air quality, and $13,269 from CO2 reduction. These totals will only go up if this ordinance is adopted by the city. The benefits described above show that by investing a small proportion of money into Oshkosh’s trees now, the city residents will eventually see a return on their investment threefold in the future. 23 Barriers: For this specific project there were not too many significant barriers. All of the stakeholders that were interviewed thought that the new tree planting ordinance would be a good idea. However, a lot of the stakeholders did mention that anytime you increase the cost of construction or increase taxes you would likely receive opposition. The additional costs of implementing this new ordinance is probably the greatest barrier. One other issue that may pose a problem is that the majority of the time when a street gets reconstructed the road also becomes wider, and the terraces get smaller, if the terraces are not removed completely. This ordinance does not directly show how the city would work around these issues. However, Oshkosh would have to balance the need for a wider street to accommodate more traffic, and the need to have a barrier of trees blocking people's homes. This comes down to an issue of safety and some of the homeowners that were interviewed stated that when Jackson St. was widened, the traffic speeds increased on the road. They did not want the same situation on their streets if or when they get reconstructed. Oshkosh also needs to weigh the economic costs and benefits of the new trees to determine what is best for the city as a whole. Another barrier that was identified is existing infrastructure and how that infrastructure needs to be worked around. When a street is reconstructed all of the infrastructure has already identified because of the construction project. Therefore, this is a prime opportunity to plant terrace trees where the existing infrastructure is not located. 24 Significance for Sustainability: The proposed ordinance aims to contribute to the sustainability goals set forth by the city of Oshkosh’s Sustainability Advisory Board. These goals reflect the three pillars of sustainability: environmental health, society, and economics. Trees provide environmental benefits to the city by improving air quality, water quality, stormwater management, and much more. They provide economic benefits by increasing property values and provide a substantial return on investment through ecosystem services. Trees also provide social benefits through their aesthetic value, as well as fostering community relationships. Mitigation of Diseases/Invasive Pests Tree disease is an ongoing issue that city planners and urban foresters must face. There are a wide variety of diseases and fungi which are transferred by invasive species, wood products, and much more. Understanding the economic and ecological impact of various tree diseases will be extremely important in shaping future tree related ordinances. Our research was focused on North American tree diseases, what causes these diseases, how to avoid tree disease, and solutions cities can implement to maintain a healthy urban forest. Many of the studies we examined were conducted in the Midwest United States or Canada and focused on many species of trees currently found in Oshkosh, such as maples, oaks, elms, and ash trees. Using the information from within these various articles, the city will be better able to include tree diversity. The city will also be able to implement management techniques to combat tree diseases and invasive pests, thus leading to a healthier urban forest. 25 The most common trend found throughout many of the articles examined, was that tree diversity is an extremely important topic. Monoculture plantings or the dominance of one tree species can lead to rapid disease outbreak and a higher susceptibility to invasive pests. One of the many examples of urban forest devastation due to monoculture plantings involves the American elm tree, which was once prolifically planted in cities across the United States, due to its aesthetic value and tall widespread canopy. Dutch elm disease (DED) was introduced to the United States around 1930, and by 1976, approximately 56% of American elms in urban areas were killed, resulting in the loss of almost 40 million American elms by 1980 (Dreistadt et al.). Diversity of tree species is the most effective management tool to avoid diseases. Many studies also stress the importance of routine observations and tree maintenance. Trees that are inspected or tested regularly by experts can easily be removed if sick, or provided with maintenance if needed. A significant amount of authors also suggest immediate removal of infected trees to prevent the spread of disease via roots, invasive pests, or airborne pathways. Experts also suggest routine pruning and in some cases pruning of diseased trees may allow the tree to stay alive, so long as the disease does not reach the main stem. A study concerning effective routes of tree maintenance suggests that the majority of pruning and tree maintenance be kept to early spring and winter months, and if possible to avoid trimming, pruning, or cutting of trees during spring and summer when diseases, pests, and spores are particularly active (Marciulyniene et al.). Urban foresters and city planners will also face another hurdle for the future, climate change. Climate change is expected to rapidly allow the movement of invasive pests and diseases to areas which are currently unaffected. Invasive pests are often times the carriers of tree diseases and have been spread around the world via plant trade, lumber trade, and much more. Human 26 actions are the number one factor causing the spread of invasive species, in this case the ones that affect trees. Due to short life cycles, capacity for dispersal, generally high reproductive rates, and sensitivity to changing temperatures, pests and pathogens have the potential to expand rapidly and adapt to new areas where they previously may not have been present. Trees, on the other hand, which are generally long lived, adapt much more slowly to changes in their local environment and makes them more vulnerable than ever to rapidly changing and moving organisms (Tubby & Webber). Tubby and Webber suggest that increased monitoring activities be conducted in urban green spaces by plant health specialists and also that monitoring should be increased concerning arboriculture and horticulture trade that may transfer non-native pests and diseases. Some studies suggest that even native pests, molds, fungi, etc. that currently have a symbiotic relationship with trees may develop into new strains which are overpopulated or deadly to tree species (Sturrock). Although climate change seems to be a vicious downward cycle, the literature suggested the best combatant to climate change related tree diseases was planning for the future by providing a broad base of tree genetics. The city of Oshkosh’s urban forest is experiencing some detrimental tree loss, especially with ash trees. Congruent with the review of tree disease literature, an interview we had with Oshkosh’s city forester, Bill Sturm, solidified the hypothesis that Oshkosh’s urban forest contains diseased trees. Sturm stated that elm trees were previously the main focus of disease and removal, but recently the city has seen an increase in emerald ash borer affecting the health of ash trees. Sturm stated that it has been a hard issue to mitigate due to the fact that him and his team can not go onto private property to treat infested trees. Encouraging homeowners to treat or remove diseased trees has proven to be difficult, therefore trees that are not treated on private 27 property are likely to aid in the spread of disease or pests to city owned trees. The Wisconsin Department of Natural Resources provides data that specifically addresses street tree benefits for the city of Oshkosh. Within their article they state, “A diverse palette of trees helps guard against catastrophic loss to insects and diseases or environmental stresses. A general guideline for urban forest diversity is no more than 5% of any one species, 10% of any one genus. Ash, maple, and crabapple trees are over-represented on Oshkosh’s streets” (WDNR). Based on the overwhelming amount of data supporting tree diversity as imperative to the health of urban forests, Oshkosh should strongly consider implementing a variety of different tree species other than ash, maple, or crabapple when planting new trees along reconstructed roads. Air Quality One of the benefits to increasing urban canopy cover through terrace tree planting is the mitigation of air pollution. The Wisconsin Department of Natural Resources quantify pollutant removal of Oshkosh street trees to total $16,332 annually, 234 pounds of particulate matter reduction, 423 pounds of ozone reduction, 19 pounds of sulfur dioxide reduction, and 71 pounds of nitrogen oxides. Nowak et al. (2006) quantified national pollutant removal provided by urban trees to total an annual amount of $3.8 billion dollars on a national level. This amount includes externality costs such as avoided medical costs. It also reflects economic and social benefits in regards to sustainability, and the pollution mitigation is important for the environmental aspect of sustainability. These nationwide statistics can be improved through sustainability efforts like those being implemented and suggested in the city of Oshkosh. Currently, the vast majority of pollutant removal (96.3%) occurs by trees on rural land, however the human health benefits are 28 concentrated in urban areas (Nowak et al, 2006). Urban trees become more important as they mitigate pollutants near the source, rather than pollutants needing to travel to rural areas to be removed. While tree diversity has already been mentioned, it is important to tie in the relationship between tree diversity and maintaining a high level of air quality. For example, American elm trees in the city of Minneapolis stored about 18.6 percent of the carbon stored by trees, however they also faced risks of Dutch elm disease. Another study by Donovan (2013) illustrated an increase in cardiovascular-related mortality and the death of ash trees caused by disease. Maintaining urban tree density and diversity is important in order to maintain the air quality benefits that can be reduced by tree disease. Stormwater Management In regards to urban planning, literature discussed the benefits and limitations of urban green infrastructure. Adult trees retain water, increase transpiration of surrounding vegetation, and increase watershed retention capacity. Trees can offer improvements to gray infrastructure by intercepting precipitation and runoff before it enters into a wastewater system (Berland et.al). Kollin and Schwab (2009) stated, “Trees and soils function together to reduce stormwater runoff. Trees reduce stormwater flow by intercepting rainwater on leaves, branches, and trunks. Some of the intercepted water evaporates back into the atmosphere, and some soaks into the ground reducing the total amount of runoff that must be managed in urban areas” (4). Urban forestry improves water quality above and below the ground, assists plant and animal wellbeing, and reduces soil erosion and pollutant washout.. 29 In one expert tree study, root depth, growth rate, and nutrient levels were measured while being subjected to stormwater and tap water. In nearly all measurements, stormwater supplies nutrients, and benefits tree growth better than tap water. This is also the case for saturation levels of water in soil. More saturated soils result in higher levels of nutrients, such as nitrogen. (Denman et al. 2015). Oshkosh nitrogen levels are high and trees are a cost effective method to regulate and remove pollutants and excess nutrients, such as those from runoff. The city of Oshkosh has acknowledged the importance of trees in their sustainability plan. Because Lake Winnebago is classified as an “impaired body of water,” the city of Oshkosh is Federally required to manage stormwater, and the proposed ordinance would be a cost effective way to do so. Aesthetics There is also a large social benefit that trees achieve through their aesthetic value, which has been noted throughout this document in both the benchmarking cities and the stakeholder interviews. While the literature on green space and the benefits for human and community health is abundant, the benefits of green space can also be extended into terrace trees and urban canopy cover. The Wisconsin DNR i-Tree analysis showed that street trees increase property values in Oshkosh by a total of $109,762 annually. Besides fostering community relationships, the aesthetic value of trees can be quantified in property values, reflective of both social and economic benefits regarding sustainability goals. According to the Oshkosh sustainability plan, the city aims to plant more trees to improve natural appearance, which coincides with the Vision 30 Oshkosh community survey. The proposed tree planting ordinance would be an efficient way to achieve these goals. Summary/Conclusion In conclusion, trees are a vital component to any ecosystem. They provide many services to both people and wildlife. Trees help reduce the amount of stormwater that the city has to manage, while at the same time reducing pollutants in the air and increasing overall air quality. Having a diverse tree population within the city helps to mitigate diseases and harmful pests. Trees increase the overall aesthetics of the city and help to build a sense of community for the city’s residents. The proposed tree planting ordinance would help improve all of these previously mentioned positive attributes. What this proposed ordinance will primarily focus on, is improving the resources that city forester Bill Sturm and his team will have to manage the city’s trees effectively and efficiently. This ordinance will give Bill Sturm a structural platform to implement his expertise in regards to the city’s public trees and further the city’s sustainability goals. With many streets in Oshkosh currently undergoing construction or scheduled for reconstruction in the near future, this is an opportune time to implement a new tree planting ordinance. Envision a city street lined with many luscious, healthy, and diverse trees; this is a vision the city of Oshkosh should strive to improve upon, and an image that would come to mind if you picture an ideal example of a certified Tree City, USA. 31 Works Cited Berland, A., Shiflett S.

Should any owner of adjacent property desire to plant a tree on any public place, a permit shall be obtained from the committee of jurisdiction in which the species, size of the tree and location shall be designated. The cost of such planting shall be borne by the property owner. (Code 1965, §13.04(5) – (8); Ord 24-12, §1, 2-21-12) Secs. 21-49 – 21-56. Reserved. ARTICLE III. TREE INSECTS AND DISEASE Sec. 21-66. Introduction. (a) Whereas, the Common Council has determined that the health of trees within the City may be threatened by insects or disease and that the loss of the trees growing upon public and private premises would substantially depreciate the market value of property within the City and impair the safety, welfare and convenience of the public, the Council hereby declares its intention to control the spread of such insects or disease. 39 (b) Declaration of public nuisance. The existence of trees, shrubs and other flora within the city are determined to be valuable public and private assets which substantially enhance the public welfare and are aesthetically significant and economically important in terms of increased value which accrue to public and private lands as a result of their existence. The continued existence of injured or diseased trees or other plantings, or the failure to properly treat the same if treatment is available, which is likely to cause the spread of disease or endanger persons because of the deteriorated condition, is hereby declared to be a public nuisance requiring abatement.
