In all cases where a transition setback is required, the requirements of this subsection shall substitute for any perimeter yard or parking lot screening requirement along the portion of any affected yard. Transition setbacks are required under the following situations:
a.
Along and within the yard(s) of a multiple family development where such multiple-family zoning or proposed multiple family development directly adjoins land zoned RE, RR, R1, R2, R3, R4, R5 or R6 or directly adjoins land designated for low density residential use in the comprehensive plan. This requirement does not apply to a multiple-family development which lies across public street right-of-way of land zoned RE, RR, R1, R2, R3, R4, R5 or R6, or otherwise designated for a low density residential use.
b.
Along and within the yard(s) of a nonresidential development where the nonresidential development or zoning district (excluding the special purpose districts) directly adjoins a residential district or land designated for any residential use in the comprehensive plan. This requirement does not apply to a nonresidential development which lies across public street right-of-way of land zoned or designated in the comprehensive plan for residential use.
2.
Landscaping:
a.
Quantity: Transition setbacks shall be improved with one medium to large shade tree for each four hundred (400) square feet of area within the setback. Sixty-six percent (66%) of the total trees required shall be evergreen trees. However, evergreen trees may replace the required number of deciduous trees at a rate of two (2) evergreen trees for each deciduous tree.
For transition setbacks greater than twenty feet (20') in depth, two (2) shrubs or one ornamental tree shall be provided for each five (5) medium to large shade trees required.
b.
Berming: Transition setbacks may include earth berms. The placement of berms is encouraged to provide a change in orientation and undulation, and not necessarily be designed in a straight and linear pattern. Plantings placed on top of berms are restricted to species compatible with the terrain.
c.
Screening: In a transition setback, berming, fencing and landscaping shall be used to provide a visual year round screen to a minimum height of six feet (6').
(1)
Exceptions In D-CM, D-RSCM And GO Districts: In the D-CM, D-RSCM and GO districts where a transition setback is required on a site proposed for adaptive reuse of an existing residential structure, or the construction of a new commercial structure, the planning and zoning commission may consider, and city council approve, alternative approaches to site screening and transition setback design which are deemed to be compatible with surrounding residential uses. In the GO district, this exception applies to land located within Area 1 only. For reuse of residential structures where no changes to the exterior of the dwelling and property are proposed for the rear yard, nor any extension of use or outdoor activity proposed, the planning and zoning commission and city council, subject to reasonable conditions, may waive the transition setback requirement. Such waiver and any conditions shall be stipulated as part of plan approval.
d.
Ground Cover: All transition setbacks, except where occupied by other landscape material shall be seeded or sodded.
H.
Landscaped Corridors:
1.
Applicability: These landscaping requirements will apply where special corridor setbacks are required as part of the CO corridor overlay zoning district which overlays a residential zoning district. The landscaping requirements for nonresidential areas shall be governed by applicable standards of this title.
2.
Landscaping Material: Setbacks in the CO corridor overlay district shall be improved with two (2) deciduous trees, one (1) ornamental tree, two (2) evergreen trees and thirty (30) shrubbery per each two hundred (200) lineal feet. Landscaping may be permitted in public street right-of-way, if authorized as part of plan approval.
Additionally, plant materials used shall include salt resistant varieties as recommended by the Illinois department of transportation.
I.
Screening And Landscaping Requirements For Building Appurtenances And Related Elements:
1.
Rooftop Mechanical Equipment: All roof mounted mechanical equipment shall be screened on all sides visible from any property line. Screening may include parapet walls or other opaque screening materials similar and compatible in color and texture to the exterior building materials on which the unit is located.
2.
Exterior Electrical And Utility Equipment: All ground mounted electrical and utility related connection and service boxes shall be effectively screened with shrubbery or other forms of living plant material to a minimum of fifty percent (50%) opacity at the time of planting. Alternative methods of screening may be approved by the director of community development where it is found that the size or positioning of the equipment to be screened presents unique conditions or difficulty in accomplishing the intent of this subsection. This provision is not intended to apply to individual service pedestals not less than eight inches by eight inches (8" × 8").
3.
Freestanding Signs: All freestanding sign locations shall provide for landscaping around the base of the sign a minimum of two feet (2') from any portion of the base of the sign. Landscaping shall include shrubbery or annual flowering plant material or other plant material, subject to the approval of the director of community development. (Ord. 95-28, 5-1-1995; Ord. 2017-19, § 3, 7-17-2017; Ord. No. 2019-17, §§ 44—47, 8-5-2019)
Cross reference— See also title 8, chapter 5, article C of this code.

2.
Methods of determining planting sizes shall be as follows. This section outlines acceptable specifications for shade trees and flowering trees:
a.
Shade And Flowering Trees: In size grading balled and burlapped trees, caliper size shall take precedence over tree height. For purposes of simplicity, only one (1) size per "grade" will be listed. That size will be the minimum size allowable for that grade and shall include plants from that size up to but not including the next larger grade size. (Example: Acer rubrum, two inch (2") caliper. This could include Acer rubrum calipering two inches (2") up to but not including 2½ inches (2½") in caliper, measured six inches (6") above the ground line.)
The caliper of the trunk shall be taken six inches (6") above the ground up to and including four inch (4") caliper size, and twelve inches (12") above the ground for larger sizes. Seldom are tree trunks perfectly round. Therefore, caliper measurement may be taken with "slot" type caliper, "pincer" type caliper, or diameter tape.
b.
Conifers And Evergreens: This subsection outlines acceptable specifications for conifers and evergreens.
For purposes of simplicity, only one (1) size per "grade" will be used. That size will be the minimum size allowable for the grade, and the grade shall include plants from that size up to but not including the next larger grade size. (Example: Taxus media "Brownii", fifteen inches (15"). This could include Taxus media "Brownii" fifteen inches (15") in height up to, but not including, eighteen inches (18") and having a minimum spread of twelve inches (12").
The following height measurement units shall apply:
3 inch intervals up to eighteen inches (18") in height.
6 inch intervals from eighteen inches (18") to four feet (4').
1 foot intervals greater than four feet (4').
c.
Deciduous Shrubs: This subsection outlines acceptable specifications for deciduous shrubs, dwarf and semi-dwarf shrubs and strong growing shrubs.
For purposes of simplicity, only one (1) size per "grade" will be used. That size will be the minimum size allowable for that grade, and the grade shall include plants from that size up to but not including the next larger grade size. (Example: Forsythia, two feet (2'). This could include Forsythia plants with not less than three (3), two-foot (2') canes up to but not including four (4), three-foot (3') canes.)
(1)
Dwarf And Semi-Dwarf Shrubs: Determine height in inches up to twenty four inches (24"); above twenty four inches (24") determine height in feet. Grade in three inch (3") series to eighteen inches (18"), six inch (6") series, eighteen inches (18") to twenty four inches (24"). (Example 12 inch; 15 inch; 18 inch; 2 feet; 2½ feet.)
(2)
Strong Growing Shrubs: Determine height in six inch (6") series up to twenty four inches (24") tall (example: 12 inches; 18 inches); over twenty four inches (24"), measure in single feet up to six feet (6') tall; over six feet (6'), measure in two foot (2') increments. (Example: five feet (5'), six feet (6'), eight feet (8'), ten feet (10').
3.
Ground Cover Specifications:
a.
Areas To Be Graded And Sodded: Areas to be sodded shall be graded smooth and topped with at least four inches (4") of black dirt after compacting and removal of stumps, trees that cannot be saved, boulders and other debris. Swales, which require sodding, shall have a minimum sodding width of ten feet (10').
b.
Areas To Be Graded And Seeded: All open areas of the development which are not paved, sodded or otherwise landscaped shall have a new lawn established through seeding. (Ord. 95-28, 5-1-1995; Ord. 2017-19, § 3, 7-17-2017)
A.
Prohibited Plant Varieties: The following list of plants are restricted from use in any areas covered by this title. The city encourages the use of native plant species indigenous to the greater Geneva region.
B.
Planting Methods: This subsection outlines guidelines for the installation of all landscape material.
1.
Most small, deciduous trees may be moved bare rooted unless otherwise indicated. Roots of bare rooted trees must be protected against drying out.
2.
All coniferous trees shall be moved balled and burlapped. Balled roots should be prevented from drying out at the surface of their ball, and they should be protected from freezing.
3.
Pits for the planting of bare root plans shall be least twelve inches (12") larger in diameter than the diameter of the root system in order to accommodate the roots without crowding. For balled trees, the pits should be a minimum of twelve inches (12") larger than the diameter of the ball of soil to allow proper backfill.
4.
Plants shall be planted no deeper than previously grown with due allowance for settling.
5.
In planting containers, artificial drainage shall be provided for the root system of any species intolerant of wet sites, or a species tolerant to wet sites shall be used.
6.
Top soil, compost, peat moss or an acceptable soil mixture may be placed about the roots of bare root stock or in the backfill around balled stock. When the planting is completed, the entire root system shall be thoroughly saturated with water and cord and burlap wrapping shall be cut and/or removed.
7.
Although pruning should be done to develop a balance with the root system, excessive pruning at the time of transplanting should be avoided.
8.
Tree trunks shall be suitably wrapped and guyed, or supported in an upright position, according to accepted arboricultural practices. The guys or supports shall be installed so that they will neither girdle nor cause serious injury to the tree nor endanger public safety. (Ord. 95-28, 5-1-1995; Ord. 2017-19, § 3, 7-17-2017)
A.
Performance Guarantee: All required landscaping materials, both living and nonliving, shall be in place prior to the time of issuance of a final certificate of occupancy, weather permitting. In periods of adverse weather conditions, a temporary certificate of occupancy may be issued, subject to the posting a performance guarantee in the form of a cash escrow, letter of credit, surety bond, or letter of commitment, issued by a bank, savings and loan association, surety, or insurance company, in favor of the city, which guaranty is deemed good and sufficient by the city, in an amount equal to one hundred ten percent (110%) the estimated cost of the landscaping. The estimated cost shall be certified by a landscape contractor. The performance guaranty may be forfeited if the landscaping is not completed within one (1) year after the issuance of the temporary certificate of occupancy. Forfeiture of any performance guarantee shall not relieve the owner of the responsibility to complete the required landscaping. The performance guarantee shall also be accompanied by a statement of the owner giving the city the right to enter upon the property to complete landscaping in the case of forfeiture.
B.
Maintenance Of Landscaping And Maintenance Bond:
1.
Trees, shrubs, and other landscaping materials depicted on landscaping plans approved by the city shall be considered to be elements of the project in the same manner as parking, building materials and other details. The developer, its successor and/or subsequent owners and their agents shall be responsible for maintenance of landscaping on the property on a continuing basis for the life of the development. Plant materials which exhibit evidence of insect pests, disease and/or damage shall be appropriately treated, and dead plants promptly removed and replaced within the next planting season after installation. All landscaping will be subject to periodic inspection by the zoning administrator, or his designee. Should landscaping not be installed, maintained and replaced as needed to comply with the approved plan, the owner and its agent or agents shall be considered in violation of the terms of the certificate of occupancy. The director of community development is empowered to enforce the terms of this chapter.
2.
As a condition to issuance of a final certificate of occupancy, a cash escrow, irrevocable letter of credit, surety bond, or letter of commitment, issued by a bank, savings and loan association, surety, or insurance company in favor of the city in the amount of twenty-five percent (25%) of the initial landscaping costs shall be posted to ensure the needed replacement of materials and the continued maintenance of the same for a period of two (2) years after initial installation. Surety may be forfeited if the necessary maintenance and replacement has not been performed in a satisfactory manner within the two-year period. Further, should it be determined that the landscaping as approved on the landscaping plan is not being maintained as specified beyond the initial two-year maintenance period, resubmission of the approved plan and the posting of an additional maintenance surety may be required by the city.
(Ord. 95-28, 5-1-1995; Ord. No. 2011-04, §§ 3, 4, 1-18-2011; Ord. 2017-19, § 3, 7-17-2017)
A.
Administrative Relief: Application for administrative relief of the requirements in this chapter may be filed with the director of community development. Ten (10) copies of the application and all supporting documentation shall be submitted. Such application shall be submitted with the landscape plan and demonstrate the following:
1.
The strict application of the regulation in question is unreasonable given the development proposal or the measures proposed by the applicant, or, that the property has extraordinary or exceptional physical conditions that do not generally exist in nearby properties in the same zoning district and such conditions will not allow a reasonable use of the property in absence of relief.
2.
Dependent upon the approval process under which the application for relief is sought, the approving authority shall make the final decision upon whether any relief from these requirements may be approved.
B.
Effect Of Approval; Plan Revisions: An application may be made following the initial submission of a landscape plan to propose alternatives or changes to the approved plan or any plans pending approval, or as may be requested by the city. Any alterations or changes to a plan document upon resubmission to the director of community development shall include plan copies required under section 11-10-5 of this chapter, above together with a written statement indicating all changes made and a revision block on the face of the plans indicating each date of revision.
All plan changes shall be represented on the face of the plans 1) by notation encompassing the area of change and with reference to the written statement of changes. Except where changes are noted, the content of the plan is presumed to be that of the last plan accepted by the director of community development. The director of community development may reject any plan changes where insufficient documentation of the location and nature of the changes 2) lends the proposed revisions uninterpretable.
Any proposed changes to a landscape plan following final action on the plan shall constitute a new application subject to the procedures and requirements of this chapter. (Ord. 95-28, 5-1-1995; Ord. 2002-53, 9-3-2002; Ord. 2017-19, § 3, 7-17-2017)

In all cases where a transition setback is required, the requirements of this subsection shall substitute for any perimeter yard or parking lot screening requirement along the portion of any affected yard. Transition setbacks are required under the following situations:
a.
Along and within the yard(s) of a multiple family development where such multiple-family zoning or proposed multiple family development directly adjoins land zoned RE, RR, R1, R2, R3, R4, R5 or R6 or directly adjoins land designated for low density residential use in the comprehensive plan. This requirement does not apply to a multiple-family development which lies across public street right-of-way of land zoned RE, RR, R1, R2, R3, R4, R5 or R6, or otherwise designated for a low density residential use.
b.
Along and within the yard(s) of a nonresidential development where the nonresidential development or zoning district (excluding the special purpose districts) directly adjoins a residential district or land designated for any residential use in the comprehensive plan. This requirement does not apply to a nonresidential development which lies across public street right-of-way of land zoned or designated in the comprehensive plan for residential use.
2.
Landscaping:
a.
Quantity: Transition setbacks shall be improved with one medium to large shade tree for each four hundred (400) square feet of area within the setback. Sixty-six percent (66%) of the total trees required shall be evergreen trees. However, evergreen trees may replace the required number of deciduous trees at a rate of two (2) evergreen trees for each deciduous tree.
For transition setbacks greater than twenty feet (20') in depth, two (2) shrubs or one ornamental tree shall be provided for each five (5) medium to large shade trees required.
b.
Berming: Transition setbacks may include earth berms. The placement of berms is encouraged to provide a change in orientation and undulation, and not necessarily be designed in a straight and linear pattern. Plantings placed on top of berms are restricted to species compatible with the terrain.
c.
Screening: In a transition setback, berming, fencing and landscaping shall be used to provide a visual year round screen to a minimum height of six feet (6').
(1)
Exceptions In D-CM, D-RSCM And GO Districts: In the D-CM, D-RSCM and GO districts where a transition setback is required on a site proposed for adaptive reuse of an existing residential structure, or the construction of a new commercial structure, the planning and zoning commission may consider, and city council approve, alternative approaches to site screening and transition setback design which are deemed to be compatible with surrounding residential uses. In the GO district, this exception applies to land located within Area 1 only. For reuse of residential structures where no changes to the exterior of the dwelling and property are proposed for the rear yard, nor any extension of use or outdoor activity proposed, the planning and zoning commission and city council, subject to reasonable conditions, may waive the transition setback requirement. Such waiver and any conditions shall be stipulated as part of plan approval.
d.
Ground Cover: All transition setbacks, except where occupied by other landscape material shall be seeded or sodded.
H.
Landscaped Corridors:
1.
Applicability: These landscaping requirements will apply where special corridor setbacks are required as part of the CO corridor overlay zoning district which overlays a residential zoning district. The landscaping requirements for nonresidential areas shall be governed by applicable standards of this title.
2.
Landscaping Material: Setbacks in the CO corridor overlay district shall be improved with two (2) deciduous trees, one (1) ornamental tree, two (2) evergreen trees and thirty (30) shrubbery per each two hundred (200) lineal feet. Landscaping may be permitted in public street right-of-way, if authorized as part of plan approval.

I.
Screening And Landscaping Requirements For Building Appurtenances And Related Elements:
1.
Rooftop Mechanical Equipment: All roof mounted mechanical equipment shall be screened on all sides visible from any property line. Screening may include parapet walls or other opaque screening materials similar and compatible in color and texture to the exterior building materials on which the unit is located.
2.
Exterior Electrical And Utility Equipment: All ground mounted electrical and utility related connection and service boxes shall be effectively screened with shrubbery or other forms of living plant material to a minimum of fifty percent (50%) opacity at the time of planting. Alternative methods of screening may be approved by the director of community development where it is found that the size or positioning of the equipment to be screened presents unique conditions or difficulty in accomplishing the intent of this subsection. This provision is not intended to apply to individual service pedestals not less than eight inches by eight inches (8" × 8").
3.
Freestanding Signs: All freestanding sign locations shall provide for landscaping around the base of the sign a minimum of two feet (2') from any portion of the base of the sign. Landscaping shall include shrubbery or annual flowering plant material or other plant material, subject to the approval of the director of community development.

B.
Minimum Planting Requirements:
1.
Minimum planting sizes shall be as follows:
a.
Large Deciduous Shade Trees: Three inches (3") caliper as measured six inches (6") aboveground.
b.
Medium Deciduous Shade Trees: Two and one-half inches (2.5") caliper as measured six inches (6") aboveground.

e.
Shrubs: Twenty-four inches (24").
f.
Ground Cover Plants: Whether in the form of crowns, plugs or containers, shall be planted in numbers appropriate by species to provide fifty percent (50%) surface coverage after one (1) growing season.
2.
Methods of determining planting sizes shall be as follows. This section outlines acceptable specifications for shade trees and flowering trees:
a.
Shade And Flowering Trees: In size grading balled and burlapped trees, caliper size shall take precedence over tree height. For purposes of simplicity, only one (1) size per "grade" will be listed. That size will be the minimum size allowable for that grade and shall include plants from that size up to but not including the next larger grade size. (Example: Acer rubrum, two inch (2") caliper. This could include Acer rubrum calipering two inches (2") up to but not including 2½ inches (2½") in caliper, measured six inches (6") above the ground line.)
The caliper of the trunk shall be taken six inches (6") above the ground up to and including four inch (4") caliper size, and twelve inches (12") above the ground for larger sizes. Seldom are tree trunks perfectly round. Therefore, caliper measurement may be taken with "slot" type caliper, "pincer" type caliper, or diameter tape.
b.
Conifers And Evergreens: This subsection outlines acceptable specifications for conifers and evergreens.
For purposes of simplicity, only one (1) size per "grade" will be used. That size will be the minimum size allowable for the grade, and the grade shall include plants from that size up to but not including the next larger grade size. (Example: Taxus media "Brownii", fifteen inches (15"). This could include Taxus media "Brownii" fifteen inches (15") in height up to, but not including, eighteen inches (18") and having a minimum spread of twelve inches (12").
The following height measurement units shall apply:
3 inch intervals up to eighteen inches (18") in height.
6 inch intervals from eighteen inches (18") to four feet (4').
1 foot intervals greater than four feet (4').
c.
Deciduous Shrubs: This subsection outlines acceptable specifications for deciduous shrubs, dwarf and semi-dwarf shrubs and strong growing shrubs.
For purposes of simplicity, only one (1) size per "grade" will be used. That size will be the minimum size allowable for that grade, and the grade shall include plants from that size up to but not including the next larger grade size. (Example: Forsythia, two feet (2'). This could include Forsythia plants with not less than three (3), two-foot (2') canes up to but not including four (4), three-foot (3') canes.)
(1)
Dwarf And Semi-Dwarf Shrubs: Determine height in inches up to twenty four inches (24"); above twenty four inches (24") determine height in feet. Grade in three inch (3") series to eighteen inches (18"), six inch (6") series, eighteen inches (18") to twenty four inches (24"). (Example 12 inch; 15 inch; 18 inch; 2 feet; 2½ feet.)
(2)
Strong Growing Shrubs: Determine height in six inch (6") series up to twenty four inches (24") tall (example: 12 inches; 18 inches); over twenty four inches (24"), measure in single feet up to six feet (6') tall; over six feet (6'), measure in two foot (2') increments. (Example: five feet (5'), six feet (6'), eight feet (8'), ten feet (10').
3.
Ground Cover Specifications:
a.
Areas To Be Graded And Sodded: Areas to be sodded shall be graded smooth and topped with at least four inches (4") of black dirt after compacting and removal of stumps, trees that cannot be saved, boulders and other debris. Swales, which require sodding, shall have a minimum sodding width of ten feet (10').
b.
Areas To Be Graded And Seeded: All open areas of the development which are not paved, sodded or otherwise landscaped shall have a new lawn established through seeding. (Ord. 95-28, 5-1-1995; Ord. 2017-19, § 3, 7-17-2017)
A.
Prohibited Plant Varieties: The following list of plants are restricted from use in any areas covered by this title. The city encourages the use of native plant species indigenous to the greater Geneva region.
B.
Planting Methods: This subsection outlines guidelines for the installation of all landscape material.
1.
Most small, deciduous trees may be moved bare rooted unless otherwise indicated. Roots of bare rooted trees must be protected against drying out.
2.
All coniferous trees shall be moved balled and burlapped. Balled roots should be prevented from drying out at the surface of their ball, and they should be protected from freezing.
3.
Pits for the planting of bare root plans shall be least twelve inches (12") larger in diameter than the diameter of the root system in order to accommodate the roots without crowding. For balled trees, the pits should be a minimum of twelve inches (12") larger than the diameter of the ball of soil to allow proper backfill.
4.
Plants shall be planted no deeper than previously grown with due allowance for settling.
5.
In planting containers, artificial drainage shall be provided for the root system of any species intolerant of wet sites, or a species tolerant to wet sites shall be used.
6.
Top soil, compost, peat moss or an acceptable soil mixture may be placed about the roots of bare root stock or in the backfill around balled stock. When the planting is completed, the entire root system shall be thoroughly saturated with water and cord and burlap wrapping shall be cut and/or removed.
7.
Although pruning should be done to develop a balance with the root system, excessive pruning at the time of transplanting should be avoided.
8.
Tree trunks shall be suitably wrapped and guyed, or supported in an upright position, according to accepted arboricultural practices. The guys or supports shall be installed so that they will neither girdle nor cause serious injury to the tree nor endanger public safety. (Ord. 95-28, 5-1-1995; Ord. 2017-19, § 3, 7-17-2017)
A.
Performance Guarantee: All required landscaping materials, both living and nonliving, shall be in place prior to the time of issuance of a final certificate of occupancy, weather permitting. In periods of adverse weather conditions, a temporary certificate of occupancy may be issued, subject to the posting a performance guarantee in the form of a cash escrow, letter of credit, surety bond, or letter of commitment, issued by a bank, savings and loan association, surety, or insurance company, in favor of the city, which guaranty is deemed good and sufficient by the city, in an amount equal to one hundred ten percent (110%) the estimated cost of the landscaping. The estimated cost shall be certified by a landscape contractor. The performance guaranty may be forfeited if the landscaping is not completed within one (1) year after the issuance of the temporary certificate of occupancy. Forfeiture of any performance guarantee shall not relieve the owner of the responsibility to complete the required landscaping. The performance guarantee shall also be accompanied by a statement of the owner giving the city the right to enter upon the property to complete landscaping in the case of forfeiture.
B.
Maintenance Of Landscaping And Maintenance Bond:
1.
Trees, shrubs, and other landscaping materials depicted on landscaping plans approved by the city shall be considered to be elements of the project in the same manner as parking, building materials and other details. The developer, its successor and/or subsequent owners and their agents shall be responsible for maintenance of landscaping on the property on a continuing basis for the life of the development. Plant materials which exhibit evidence of insect pests, disease and/or damage shall be appropriately treated, and dead plants promptly removed and replaced within the next planting season after installation. All landscaping will be subject to periodic inspection by the zoning administrator, or his designee. Should landscaping not be installed, maintained and replaced as needed to comply with the approved plan, the owner and its agent or agents shall be considered in violation of the terms of the certificate of occupancy. The director of community development is empowered to enforce the terms of this chapter.
2.
As a condition to issuance of a final certificate of occupancy, a cash escrow, irrevocable letter of credit, surety bond, or letter of commitment, issued by a bank, savings and loan association, surety, or insurance company in favor of the city in the amount of twenty-five percent (25%) of the initial landscaping costs shall be posted to ensure the needed replacement of materials and the continued maintenance of the same for a period of two (2) years after initial installation. Surety may be forfeited if the necessary maintenance and replacement has not been performed in a satisfactory manner within the two-year period. Further, should it be determined that the landscaping as approved on the landscaping plan is not being maintained as specified beyond the initial two-year maintenance period, resubmission of the approved plan and the posting of an additional maintenance surety may be required by the city.
(Ord. 95-28, 5-1-1995; Ord. No. 2011-04, §§ 3, 4, 1-18-2011; Ord. 2017-19, § 3, 7-17-2017)
A.
Administrative Relief: Application for administrative relief of the requirements in this chapter may be filed with the director of community development. Ten (10) copies of the application and all supporting documentation shall be submitted. Such application shall be submitted with the landscape plan and demonstrate the following:
1.
The strict application of the regulation in question is unreasonable given the development proposal or the measures proposed by the applicant, or, that the property has extraordinary or exceptional physical conditions that do not generally exist in nearby properties in the same zoning district and such conditions will not allow a reasonable use of the property in absence of relief.
2.
Dependent upon the approval process under which the application for relief is sought, the approving authority shall make the final decision upon whether any relief from these requirements may be approved.
B.
Effect Of Approval; Plan Revisions: An application may be made following the initial submission of a landscape plan to propose alternatives or changes to the approved plan or any plans pending approval, or as may be requested by the city. Any alterations or changes to a plan document upon resubmission to the director of community development shall include plan copies required under section 11-10-5 of this chapter, above together with a written statement indicating all changes made and a revision block on the face of the plans indicating each date of revision.
All plan changes shall be represented on the face of the plans 1) by notation encompassing the area of change and with reference to the written statement of changes. Except where changes are noted, the content of the plan is presumed to be that of the last plan accepted by the director of community development. The director of community development may reject any plan changes where insufficient documentation of the location and nature of the changes 2) lends the proposed revisions uninterpretable.
Any proposed changes to a landscape plan following final action on the plan shall constitute a new application subject to the procedures and requirements of this chapter. (Ord. 95-28, 5-1-1995; Ord. 2002-53, 9-3-2002; Ord. 2017-19, § 3, 7-17-2017)
