9. Security:
a. Landscape Security Required: Prior to the issuance of a building permit for all projects requiring approval of a landscape plan, the developer, contractor, or property owner shall deposit a security with the City to guarantee compliance with and to indemnify the City for any expenses incurred in enforcing the requirements of this Section.
i. One- and Two-family Dwellings: Landscape security for detached or attached one- or two-family dwellings shall be a cash escrow in the amount of $500.00.
ii. All Other Uses: Landscape security for all uses except detached or attached one- or two-family dwellings shall be in a form approved by the Community Development Department and shall be equal to 125% of the estimated cost necessary to furnish and plant the required landscaping and any ancillary screening improvements such as fencing. The estimated cost shall be subject to approval by the City. If the estimated cost submitted by the developer to the City is not approved by the City, the City shall have the exclusive right to determine the estimated cost.
b. Landscape Inspection: The developer, contractor, or property owner shall request an inspection after the required landscaping has been installed. The Community Development Department will perform the inspection and determine compliance with the approved landscape plan.
c. Releasing the Security: Upon the determination by the Community Development Department that a landscape installation is consistent with landscape requirements and approved plans, the security shall be released to the developer, contractor, or property owner according to the requirements below.
i. One- and Two-family Dwellings: A required security shall be released upon the successful inspection of the landscape installation. Notwithstanding the foregoing, no portion of the security shall be released while there are unsatisfied obligations.
ii. All Other Uses: The landscape security for all uses except detached or attached one- or two-family dwellings shall be held by the Community Development Department for a minimum of 2 full years beginning upon the successful inspection of the landscape installation. A reduction can be sought after the first year and after an inspection is requested by the developer, contractor, or property owner. If the Community Development Department determines that the landscape is established appropriately, a portion of the security may be released. That part of the security which has not been released at the end of the first year shall be retained and shall secure the remaining obligation to replant trees which are not alive or are unhealthy at the end of the year and to replant missing trees. The entire security may be released 1 year after the replanting of such trees has been satisfactorily completed and the City has certified that those replacement trees are alive and healthy. To be certified as alive and healthy, all of the following conditions must exist:
--No tree shall have sustained mechanical injury to the trunk of a tree causing loss of more than 30% of the bark circumference of the tree at any location along the tree’s trunk.
--No tree shall have had soil compacted to 6 inches deep over more than 30% of its root zone.
--No tree shall have had more than 30% of its roots cut for the installation of any utility or for any other purpose.
--No more than 25% of the crown of a tree shall consist of dead branches.
d. None of a security shall be released until the developer’s, contractor’s, property owner’s obligations to indemnify the City for any expenses incurred in enforcing the requirements of this Section are satisfied.
10. Penalties for Violation: Any tree that is visibly damaged, has a root system that has been driven on, or has a root zone in which the soil has been compacted in any way, shall be replaced in accordance to the tree replacement formula found in Section 1011.04G. Also, any person who is not authorized by the City who removes any tree from any public property without first obtaining a permit and any person who fails to replace trees in the manner provided in this subsection shall, in addition to the criminal penalties prescribed by law, be required to pay to the City the estimated cost of tree replacement in the amount determined by the City. Upon determination that this has occurred, the City shall submit a bill for the amount of tree replacement. If that amount is not received by the City within 90 days, such amount shall be assessed as a special assessment on any land located in the City owned by the person violating this Section.
B. Buffer Area Screening: The setback requirements established for uses in each district are intended to act as buffers between those districts and uses, but heightened screening is appropriate between low-density residential dwellings and more intensive uses. For all new construction in all districts that lie adjacent to or across the street from LDR Districts, therefore, additional screening shall be implemented as required herein.
1. Exception: The requirements in this subsection shall be applied in addition to the preceding general landscaping requirements, except that they shall not apply to Low Density Residential or Park and Recreation Districts.
2. Acceptable Screening: Screening requirements of this Title shall be satisfied through the use of buildings, berms, solid board-on-board fences, walls, planting screens, evergreen trees, hedges, or some combination thereof. If the topography, existing vegetation, permanent structure, or other feature creates a barrier which achieves the standards of this section, they may be substituted.
a. Screen Fences and Walls: Any screen fence or wall shall be constructed of attractive, permanent finished materials, compatible with those used in the construction of the principal structure. Such screens shall be at least 6 feet in height and shall be 100% opaque.
b. Planted Screening: Any planting screens shall consist of healthy plants, shall be at least 6 feet in height, and shall be designed to provide a minimum year round opacity of 80% at the time of installation.
c. Notwithstanding these requirements, screening along street rights-of-way shall be maintained at a height not less than 3 feet nor more than 4 feet.
3. Maintenance: Screen fences and walls which are in disrepair shall be promptly repaired. Planted screens shall be maintained according to the normal landscape maintenance requirement of Section 1011.03A8
C. Parking Lot Landscape: Off street parking lots with more than 25 parking stalls shall contain interior landscaped islands. Such islands shall be bounded by a raised concrete curb or approved equivalent and shall contain mulch to retain soil moisture. Turf grass is permitted within landscaped areas located around the periphery of a parking lot.
1. Islands are required at the end of each row of cars, where it abuts vehicle circulation aisles or driveways, or every 15 stalls, whichever is less.
2. Islands shall be provided to separate pedestrian and vehicular traffic.
3. All islands shall contain a minimum of 160 square feet and a minimum dimension shall be 5 feet.
4. At least 1 canopy tree shall be provided in each island, in addition to assorted shrubs, perennials, to assorted ornamental grass.
5. Islands shall be prepared with clean soil to a depth of 5 feet and amended to ensure adequate drainage and nutrient and moisture-retention levels for the establishment of plantings.
D. All perimeter and interior landscaped areas in parking lots shall be equipped with a permanent irrigation system, unless drought-tolerant plant materials are used exclusively. Where drought-tolerant plant materials are used, irrigation shall be required only for the two-year period following plant installation and may be accomplished using hoses, water trucks, or other nonpermanent means.

iii. No major insect or pathological problem.
b. A smaller tree can be considered a heritage tree if:
i. Certified forester determines it is a rare or unusual species or of exceptional quality.
ii. A smaller tree can be considered a heritage tree if it is specifically used by a developer as a focal point in the project.
4. Other Trees: A tree not included on Table 1011-1 or Table 1011-2 may be included for credit as part of the Tree Inventory subject to City approval if it has:
a. A life expectancy of greater than 10 years;
b. A relatively sound and solid trunk with no extensive decay or hollow; and
c. No major insect or pathological problem; and if
d. A certified forester determines it is a rare or unusual species or of exceptional quality; or
e. It is specifically used by a developer as a focal point in the project.
E. Tree Protection: All trees which are to be retained on any site shall be marked and physically protected from harm or destruction caused by soil compaction, equipment and material storage within the drip line, bark abrasions, changes in soil chemistry, out-of-season pruning, and root damage during construction.
1. Before any construction or grading of any development project occurs, a “safety fence” at least 4 feet in height, and staked with posts no less than every 5 feet shall be placed around the drip line borders of woodlots and/or the drip lines of significant trees to be preserved. Signs shall be placed along this fence line identifying the area as a tree protection area, and prohibiting grading beyond the fence line. This fence must remain in place until all grading and construction activity is terminated.
2. No equipment, construction materials, or soil may be stored within the drip lines of any significant trees to be preserved.
3. Care must be taken to prevent the change in soil chemistry due to concrete washout and leakage or spillage of toxic materials such as fuels or paints.
4. Drainage patterns on the site shall not change considerably causing drastic environmental changes in the soil moisture content where trees are intended to be preserved.
5. Pruning of oak and elm tree branches and roots must not take place from May 1 through July 31. If wounding of oak or elm trees occurs, a nontoxic tree wound dressing must be applied immediately. Excavators must have a nontoxic tree wound dressing with them on the development site.
6. Any tree determined by the Community Development Department to be destroyed or damaged shall be replaced in accordance with the Tree Replacement Formula in Section 1011.04G.
F. Allowable Tree Removal:
1. Pursuant to an approved tree preservation plan, significant trees may be destroyed without any required replacement within the width of required easements for public streets, utilities, and storm water ponding areas.
2. Development of Vacant Lots: On individual lots, up to 35% of the total DBH-inches of all significant trees and up to 15% of the total DBH-inches of all heritage trees may be removed for the installation of utilities, driveways, and the building pad without tree replacement or restitution.
3. Redevelopment of Lots: On lots which have been previously platted and developed, where the structures have been removed or destroyed to more than 50% of the current market value, up to 35% of the total DBH-inches of all significant trees and up to 15% of the total DBH-inches of all heritage trees may be removed for the installation of utilities, driveways, and building pads without tree replacement or resolution.
4. Significant trees in excess of the limitations of this Section may be removed, provided all trees removed in excess of said limitations shall be replaced in accordance with the Tree Replacement Formula.
G. Tree Replacement Formula: Replacement of removed or disturbed trees in excess of that which is allowed under a tree preservation plan shall be according to the following guidelines:
1. Significant Trees: Significant trees shall be replaced at the ratio of 0.5 caliper inch per 1 DBH-inch removed.
2. Heritage Trees:
a. Due to their inherently greater value, heritage trees shall be replaced at a ratio of 2 caliper inches per DBH-inch.
b. For each heritage tree saved, the developer may receive credit towards the required replacement trees. This credit will be at a rate of 2 caliper inches for each DBH-inch saved. To receive this credit, the applicant must demonstrate that extraordinary measures have been taken to preserve the heritage trees that otherwise would not be saved.
3. Required replacement trees shall be planted on the site being developed. The applicant may also request approval to plant replacement trees on boulevards, at the discretion of the City.
4. Minimum sizes for replacement trees shall be:
a. Deciduous Trees: 3-inch caliper
b. Coniferous Trees: 6 feet in height
5. Replacement trees shall be from balled and burlapped, certified nursery stock as defined and controlled by MN Stat. 18.44 through 18.61, the Plant Pest Act, as may be amended from time to time. Replacement trees may also be from bare root stock, provided the trees are planted no later than May 15th in any year, and the planting is inspected by the City.
6. Replacement trees shall be covered by a minimum 2-year guarantee.
7. Replacement trees shall be of a species similar to other trees found on the site where removal has taken place. Selection of replacement tree types for use on public sites shall be at the sole discretion of the City.
8. Where heritage trees have been removed, replacement trees shall consist of the same species as the removed heritage tree, or a tree that has the same potential value as the removed heritage tree. This value shall be certified by a certified forester or arborist. For the purposes of this paragraph, value is defined as a species which has the same growth and life potential as the removed tree.
9. Replacement trees may be utilized to meet landscaping and screening requirements if placement, species, and location are consistent with those requirements.
H. Certification of Compliance with Approved Landscape Plan: Upon completion of the required landscape installation, the Developer shall notify the City and request an inspection of the work. Following the inspection, the City shall notify the Developer that all work has been satisfactorily completed, or what work is still required. The required warranty period, shall begin on the date of the letter of satisfactory completion issued by the City.
I. Warranty Requirement:
1. New Development Sites: The Developer shall provide a financial guarantee, in a form satisfactory to the City, prior to the approval or issuance of any permit for land alteration.
a. The amount of the guarantee shall be 125% of the estimated cost to furnish and plant replacement trees. The estimated cost shall be provided by the Developer subject to approval by the City. The estimated cost shall be at least as much as the reasonable amount charged by nurseries for the furnishing and planting of replacement trees. The City reserves the right in its sole discretion to determine the estimated cost in the event the Developer’s estimated cost is not approved.
b. The security shall be maintained for at least 2 years after the date that the last replacement tree has been planted. Upon a showing by the Developer and such inspection as may be made by the City, that portion of the security may be released by the City equal to 125% of the estimated cost of the replacement trees which are alive and healthy at the end of such year. Any portion of the security not entitled to be released at the end of the year shall be maintained and shall secure the Developer’s obligation to remove and replant replacement trees which are not alive or are unhealthy at the end of such year and to replant missing trees. Upon completion of the replanting of such trees the entire security may be released.
2. Development or Redevelopment of Existing Lots: The developer shall provide a cash escrow in the amount of $500.00 to guarantee compliance with the requirements of this Ordinance. Said security shall be released upon certification of compliance by the developer to the satisfaction of the City. Notwithstanding the foregoing, no portion of the security shall be released while there are unsatisfied Developer’s obligations to indemnify the City for any expenses in enforcing this requirement.
3. The City may retain from the security required above as reimbursement an amount expended by the City to enforce the provisions of this Section.
J. Entry on Private Property and Interference with Inspection: The Community Development Department may enter upon private premises at any reasonable time for the purposes of enforcing the regulations set forth in this Section. No person shall unreasonably hinder, prevent, delay, or interfere with the Community Development Department while engaged in the enforcement of this Section.
