CITY PROPOSAL:
The city of Duluth does ordain:
Section 1. That Section 50-25.2.P of the Duluth City Code, 1959, as amended, be amended as follows:
50-25.2.P Tree preservation requirements.
P. Protection of Required Landscaping Trees
Maintenance of landscaping required by this chapter, or landscape areas shown on site plans submitted as part of a zoning permit or building permit approval, is the ongoing responsibility of the property owner and his or her successors. Trees and vegetation that have died must be replaced.
Trees required by this section that are placed within 5 feet of a driving or parking surface shall be placed behind a raised curb, or planter, or similar physical barrier or obstacle to protect the tree trunks from interference by vehicles or snow removal operations. Curb openings for sidewalks or for drainage to the landscape areas are allowed.
Tree soil shall have a minimum depth of 2 feet and shall not contain different soil layers. The soil may not have any herbicides, heavy metals, biological toxins, or hydrocarbons that will impact plant growth or are at levels exceeding the EPA’s standards for soil contaminants. No stones or particles greater than 1 inch in the longest dimension are permitted. This includes fragments of brick, concrete, wood, glass, metal, stone and plastic.
Section 2. That Section 50-25.9 of the Duluth City Code, 1959, as amended, be amended as follows:
50-25.9 Tree preservation requirements.
A. Purpose.
The city recognizes that trees provide numerous benefits and services to city residents, including increased property values reduced stormwater runoff and soil erosion with associated cost savings, noise buffering, aesthetic value, reduced energy costs from shade in summer and windbreaks in winter, and removal of greenhouse gases and other pollutants from the air. The city seeks to maintain the tree cover that protects the city’s water quality and gives the city its character, while recognizing the need to remove some trees for development, safety, view preservation and other purposes;
B. Tree replacement.
1. Exemptions.
The following activities are not subject to the tree replacement requirement in this Section 50-25.9:
(a) Forest management activities that maintain pre-existing tree canopy cover, such as minor thinning that eliminates no more than 25 percent of the canopy;
(b) Forestry activities that disturb the canopy are exempt if covered by a current forest management plan approved by the city forester;
(c) Removal of trees that are an obstruction to traffic or power lines or other utilities;
(d) Removal of trees necessary for rescue in an emergency or for clean-up after a natural disaster;
(e) Removal of public trees deemed hazardous by the city forester;
(f) Removal of trees that are airport hazards;
(g) Removal and trimming of trees along Skyline Parkway to preserve views from established or historic overlooks and viewpoints, with approval by the city forester;
(h) Installation or replacement of city streets or utilities;
2. Replacement required.
(a) Tree replacement shall be required pursuant to Table 50-25-3;

(b) Removal of special tree species over 20 inches diameter at breast height (DBH) or greater is prohibited unless any of the following applies:
(i) The city forester determines that the tree is dead, dying, diseased or a threat to public health or safety;
(ii) The city engineer determines that the tree interferes with the provision of public services or is a hazard to traffic;
(iii) The land use supervisor determines that the location of the tree is preventing development or redevelopment that cannot be physically designed to protect the tree;
(c) When ten or more replacement trees are required, not more than 30 percent shall be the same species without approval from the city forester;
(d) Replacement trees provided pursuant to this Section 50-25.9 shall count towards landscaping required under other portions of this Section 50-25.9 if they meet the size, type and location standards for the type of landscaping required;
(e) Replacement trees shall be considered significant trees in any future tree replacement plan;
(f) If any part of the property is permanently protected from development by a conservation easement or by transfer to a city park or other natural area or a private conservation organization, the combined diameter of the protected trees that meet the size requirement for a significant tree will count toward the replacement requirement;
(g) With the approval of the appropriate city staff (land use supervisor or city forester), developers should have the option of meeting the tree replacement requirements by putting equivalent funds into a dedicated city tree account. The amount of funds should be calculated based on the cost to the city of hiring contractors to plant the number of required replacement trees;
3. Calculation.
(a) If you meet the removal threshold:
__________________ x __________% = replacement requirement
Inches removed(DBH) % DBH in inches
(b) If replacing with special trees:
Replacement requirement ÷ 1.5 = Total inches required
(c) If replacing with other trees:
Replacement requirement = Total inches required;
4. Example.
Step 1: Removal of 12 10 inch- in. special trees = Total of 120 in. DBH
Step 2: 120 in. DBH x 25% = 30 inch in. replacement requirement
Step 3: If replacing with special tree species: 30 inch in. ÷ 1.5 = 20 inch in. total inches required to be planted;
5. Tree replacement plans.
Where this replacement requirement applies, the applicant shall submit a tree replacement plan prepared and certified by a certified forester, arborist or landscape architect. The tree replacement plan shall be part of and integrated with the landscaping plan for the site. No replacement shall occur until the city forester has approved the tree replacement plan, and all replacement shall be consistent with that approved plan. The plan shall meet all applicable requirements in the UDC application manual;
6. Calculation for developments exceeding five acres.
For development of forested acres over five acres, with the approval of the appropriate city staff, the total diameter of trees removed should be able to be estimated based on measuring the diameter of trees in representative sample plots. The plots should be scattered throughout the area to be cleared and should cover no less than ten percent of the entire area. All special tree species in the forest must be measured.
