(A) Purpose and Applicability
(1) The purpose of the site development standards is to facilitate the implementation of the Bridge Street District Area Plan and establish a walkable, mixed-use urban core for the City of Dublin consistent with the principles and directions articulated in the Community Plan (Bridge Street District Area Plan). It is intended that all site development encourage and support the principles of walkable urbanism provided in §153.057(D).
(2) As provided in §153.065, the site development standards shall be applied to all new development in the Bridge Street District, including modifications to Existing Uses and Existing Structures.
(3) With the exception of provisions related to Existing Uses in §153.059(B)(5) and Existing Structures in §153.062(B)(2), site development standards covered by this section that are nonconforming at the effective date of this amendment or made nonconforming by a change to this chapter shall meet the requirements of §153.004(C).
(B) Parking and Loading
The intent of §153.065(B) is to ensure the provision of adequate vehicular and bicycle parking facilities in all BSD zoning districts based on the vision for each area described in the Dublin Community Plan (Bridge Street District Area Plan) and the District’s five Vision Principles. This is achieved through the emphasis placed on required bicycle facilities, well-designed parking structures and the use of on-street parking spaces while minimizing off-street surface parking lots and encouraging shared parking arrangements.
(1) General Provisions
1. Vehicular and bicycle parking as required by §153.065(B) shall be provided for the use of occupants, employees and patrons of each new building or addition constructed. Required parking shall be provided as permitted by this section, including, but not limited to, shared parking arrangements.
2. Parking meeting the requirements of this section shall be provided for buildings that are expanded by more than 25% of the gross floor area existing on the effective date of a rezoning to a BSD zoning district.
3. Whenever the use of a building or lot is changed to a use requiring 25% or more parking spaces than the required parking for the previous use, parking shall be brought into full compliance as required by §153.065(B) within a reasonable time as determined by the Director. For a multi-tenant building, when a portion of the building or lot changes to a use requiring 25% or more parking spaces, only that parking for the new use shall be required. If applicable, a shared parking plan as described in §153.065(B)(2)(b) may also be submitted to ensure adequate parking while accommodating changes of use in multi-tenant buildings.
4. Required parking and loading spaces shall be installed and completed prior to building occupancy. The Director of Building Standards may grant one, six month extension following occupancy approval if adverse weather conditions or unusual delays beyond the control of the property owner prevent completion of parking and loading areas. Adequate parking areas and spaces shall be available, either on or off-site, during the extension period under the following conditions:
A. On-site parking areas, if not in a finished condition, shall be adequately surfaced to accommodate anticipated traffic, stormwater drainage and snow removal, at the determination of the Director of Building Standards; and/or
B. Parking may be provided off-site, subject to the requirements of §153.065(B)(1)(b).
5. The provisions of §153.207, Parking in Residential Districts, shall apply in the BSD Residential and BSD Historic Residential districts.
6. Parking and loading spaces for uses not addressed in §153.065(B) shall be determined by the Director based on the anticipated parking impacts of the proposed use, its similarity to characteristics of other listed uses, and supporting documentation that may be provided by the applicant.
7. Parking for Existing Structures is governed by the provisions of §153.062(B)(2)(c).
(b) Parking Location
1. On-Site Parking
A. Surface parking provided on-site may only be located on those areas of each development parcel that are not required by §153.062 to be occupied by a principal structure. Off-street parking may also be provided within a principal structure as permitted by §153.062(O). The parking areas shall be readily accessible by vehicles, bicycles, and pedestrians.
B. Parking shall not be located within a setback as required for individual building types in §153.062(O), except that parking areas may extend across contiguous lots in developments with coordinated site design, shared access points and/or shared parking arrangements.
C. Where on-site surface parking is provided on a site included as part of a Development Plan Review, parking may be permitted by the required reviewing body to encroach required setbacks to facilitate coordinated site design and contiguous parking areas with future development phases.
2. Off-Site Parking
Required off-street parking shall be provided either on-site, or in a parking structure or surface parking lot located within 600 feet of the subject parcel as permitted by the BSD zoning district in which the parking lot or structure is located and shall be readily accessible by vehicles, bicycles, and pedestrians.
A. The use of off-site parking to meet the minimum parking requirement shall require an approved parking plan as described in §153.065(B)(1)(f). If not under single ownership, provisions for off-site parking shall be made by binding agreements between two or more property owners. Written easements which provide for continued use and maintenance of the parking shall be submitted to the City for approval. Any agreement shall include provisions to address changes in use or ownership.
B. If an off-site parking agreement is severed or modified with the result of eliminating required parking for one or more properties, parking for the affected properties shall be brought into full compliance as required by §153.065(B), and approval of a new or modified parking plan shall be required.
C. If located off-site, distances to required parking areas shall be measured along a walkway from the nearest pedestrian entrance to the parking area to the main entrance to the principal structure or use being served.
3. On-Street Parking
On-street parking spaces may be counted toward meeting the minimum parking requirement for a parcel provided that the spaces are on the same side of the street and more than one-half the length of the parking space lies between the two side lot lines of the parcel extended into the street right-of-way. On corner lots, on-street spaces on both street frontages may be counted in the same manner. Credit for on-street parking spaces shall apply to parking for all uses on the parcel rather than any specific use. On-street parking spaces shall not be signed or otherwise designated for exclusive use by any specific use, building or lot.
(c) Electric Car Charging Points
Parking lots and structures are strongly encouraged to provide at least one electric plug-in service point for every 200 parking spaces. Plug-in points shall be associated with an individual parking space and shall be installed according to appropriate design standards, as approved by the Director. Plug-in points are exempt from the service structure screening requirements of §153.065(E).
(d) Parking Lot/Structure Lighting
Parking lot and parking structure lighting shall comply with the requirements of §153.065(F).
(e) Parking Lot Landscaping
Parking lot landscaping shall comply with the requirements of §153.065(D).
(f) Parking Plan Required
1. A parking plan demonstrating compliance with the provisions of §153.065(B) is required for the following conditions:
A. Applications for Site Plan Review;
B. Applications that include a request for off-site parking, or in any case where a modified parking agreement necessitates a new or modified parking plan as described in §153.065(B)(1)(b);
C. Applications involving a use listed in Table 153.065-A for which the parking requirement is specifically noted as being determined by an approved parking plan;
D. Applications that include a request for an adjustment to required vehicle parking as permitted in §153.065(B)(2)(b), or where a change in conditions renders an approved adjustment insufficient to meet the parking needs of a use, building or lot;
E. Applications that include a request for an adjustment to the number or location of required loading spaces as permitted in §153.065(B)(7), which may be approved by the Director where a change in conditions renders an approved adjustment insufficient to meet the loading needs of a use, building or lot;
F. Applications for a Certificate of Zoning Plan Approval for a change of use that requires 25% or more parking spaces than the previous use; or
G. Other circumstances determined by the Director to require a parking plan, which shall be reviewed with the Certificate of Zoning Plan Approval application.
2. Each parking plan for a parking area that contains 50 or more parking spaces shall demonstrate compliance with the pedestrian circulation standards of §153.065(I)(3)(b).
3. A parking plan shall include, at a minimum, the following, as applicable:
A. Required parking computation in accordance with Table 153.065-A and the numbers of parking spaces to be provided.
B. Information regarding any requested parking adjustments in accordance with §153.065(B)(2)(b).
C. Demonstration of parking need, in accordance with §153.065(B)(2)(b)6.
D. Signed and executed easements, agreements, or other documentation required to ensure that spaces counted toward the parking requirements are properly secured.
E. Site plan(s) for planned parking areas covered by the parking plan indicating locations of planned parking, names of property owners for properties not under the direct control of the applicant, and any other related site details relevant to the parking plan application.
F. Any other information required by the Director to ensure an adequate review of the parking plan application.
(2) Required Vehicle Parking
(a) Minimum Amount Required and Maximum Amount Permitted
1. Each use shall provide the minimum amount of parking required for that use listed on Table 153.065-A, and shall be permitted to provide up to the maximum amount of parking on-site, as indicated for that use in Table 153.065-A, except as may be modified by the provisions of §153.065(B).
2. When calculating minimum and maximum parking requirements, fractional numbers shall be increased to the next whole number.
3. Unless otherwise noted, all square footage requirements are based on indoor gross floor area.
4. Except as noted in Table 153.065-A, no additional parking is required for accessory or temporary uses when the square footage of the uses are included in the parking calculation for the gross floor area of the principal use.
(b) Adjustments to Required Vehicle Parking
The maximum on-site parking requirements may not exceed that permitted by Table 153.065-A unless a parking plan meeting the criteria of §153.065(B)(2)(b)6, below is approved by the required reviewing body. The minimum amount of parking required by Table 153.065-A may be reduced by approval of a parking plan meeting the requirements of §153.065(B)(2)(b)1-6. The cumulative reduction of minimum parking requirements permitted by §153.065(B)(2)(b)1-5 shall not exceed 30% of required parking, regardless of the number of these adjustments applied. Additional reductions may be permitted by §153.065(B)(2)(b)6.
1. Shared Parking Calculations
Where a mix of land uses creates staggered peak periods of parking, shared parking plans that have the effect of reducing the total amount of needed parking spaces may be approved. Parking spaces included in shared parking plans should be equally accessible and available to each of the affected users. The collective provision of off-street parking for two or more buildings or uses may be permitted subject to the following:
A. Shared parking plans may include any lot or structure meeting the parking location requirements of §153.065(B)(1)(b). Adjacent lots included in the shared arrangement shall be connected for vehicular passage and shall provide safe and efficient pedestrian access to all uses served by the parking area(s).
B. A request for a shared parking reduction shall be based on a shared parking analysis, including, but not limited to, the following factors:
i. The number of originally required spaces for different uses or facilities sharing the same parking areas as noted in Table 153.065-A; and
ii. Documentation of required parking needed for different uses at different days and times.
C. The adjusted required parking for shared parking areas shall be the largest number of spaces needed for all uses during the most intensive time period of use expected on a typical basis.
2. Auto-Share Parking Spaces
The required minimum number of off-street parking spaces may be reduced by four spaces for each parking space reserved for auto-share parking, not to exceed a 10% reduction in the required minimum number of spaces provided in any one parking lot or structure. Auto-share parking spaces shall be designated on a parking plan and signed for the exclusive use of auto-share vehicles and evidence of written measures shall be provided to the City to ensure that the auto-share spaces are used only for that purpose.
3. Transit Proximity
The required minimum number of off-street parking spaces may be reduced by 10% if more than 50% of the land in a proposed development is located within 1,320 feet of any public transit stop. If an existing transit stop is subsequently eliminated, any previously permitted parking reduction shall remain valid, provided that an active transit route remains within 1,320 feet of the development.
4. Shower Facilities
The required minimum number of off-street parking spaces for a non-residential development may be reduced by 5% if a development contains shower and clothing locker facilities for bicycle commuting employees or patrons. The reduction shall apply only to that portion of the minimum parking requirement attributable to the tenant(s) or user(s) that have access to the shower and locker facilities. If the shower or locker facilities are later eliminated, the reduction of the minimum required parking shall no longer apply and parking shall be provided in accordance with §153.065(B).
5. Transportation Demand Management
As an alternative or supplement to the other adjustments in subsection §153.065(B)(2)(b), off-street parking requirements may be reduced by up to 30% through the use of a Transportation Demand Management (TDM) program approved by the Director and the City Engineer.
A. Parking Demand Study Required
Before a TDM program may be approved, the applicant shall submit a parking demand study prepared by a traffic engineer or other qualified transportation professional determined to be acceptable to the Director and the City Engineer. The study shall document that the use of alternative modes of transportation, including transit, bicycles, walking, and/or the special characteristics of the customer, client, employee, or resident population will reduce expected vehicular use and parking space demands for the use, as compared to the Institute of Transportation Engineers vehicle trip generation rates and the minimum parking requirements established in Table 153.065-A.
B. Transportation Demand Management (TDM) Activities
The TDM program must include at least two of the following established and maintained activities in order to qualify for a reduction in off-street parking requirements:
i. Carpooling, vanpooling, ridesharing, guaranteed ride home, telecommuting, and/or shuttle service programs;
ii. Staggered or alternative work scheduling, allowing employees to arrive and depart at different times so that peak parking demands associated with mass shift changes are minimized;
iii. Dissemination of information to employees, residents, and visitors to the site regarding the TDM plan and alternatives to single-occupancy vehicle travel to the site through an on-site office or project-specific web site; or
iv. Use of alternative TDM activities that the Director and the City Engineer determine are likely, in combination with other TDM measures, to result in at least 30% reduction in single-occupancy vehicle travel to and from the site, as compared to the Institute of Transportation Engineers vehicle trip generation rates.
C. TDM Annual Report
i. The owner of the parcel or principal structure must provide an annual report to the Director and City Engineer describing the implementation strategies for the approved TDM plan as approved. The report shall include a description of the TDM activities, a list of current tenants and number of employees for each tenant, and a parking-reduction analysis based on employee and/or resident use of ridership programs or alternative transportation options.
ii. If the report does not document reasonable progress toward a 30% reduction in the Institute of Transportation Engineers vehicle trip generation rate of single-occupancy vehicle travel to and from the site, then the report shall identify what changes to the TDM plan or activities are being made to further reduce single-occupancy vehicle travel to and from the site. The Director and the City Engineer may require additional parking facilities to be constructed or a fee from the owner of the parcel or primary structure to be used for the construction of additional parking facilities or improvements to offset the impact of the single-occupancy vehicles.
6. Demonstration of Parking Need
In addition to or in lieu of parking adjustments as described in §153.065(B)(2)(b)(1)-(5), the required reviewing body shall be permitted to approve a parking plan for fewer than the minimum required parking spaces or more than the maximum permitted parking spaces based on a demonstration of parking need by the applicant. The required reviewing body shall consider:
A. The land use and development character of the area to be served by the parking facility, including the relative intensity of uses requiring parking, availability of transit, proximity of nearby employment centers and residential uses, and other relevant factors;
B. The availability of other publicly available parking in the area, including information such as number of spaces, any applicable restrictions (time limits, dedicated parking areas, etc.), or other uses also counting spaces in the same parking area for meeting parking requirements;
C. The timing of parking use relative to other uses in the area including information regarding hours of operation or other operational parking needs that would permit use of the spaces;
D. The parking requirement for similar uses where applicable, as may be determined by the Director, as described in §153.065(B)(1)(a);
E. Whether the location of all provided parking meets the requirements of §153.065(B)(1)(b);
F. Whether compliance with Table 153.065-A is made to the maximum extent practicable taking into account parking lot design and efficiency of the layout;
G. Whether other adjustments as described in this section should apply in conjunction with or in lieu of the requested need-based adjustment; and
H. Whether supporting documentation, if provided, adequately demonstrates that sufficient parking is available to meet projected typical demand.
(c) Accessible Parking Spaces
1. Within the total number of off-street parking spaces provided, a minimum number of spaces shall be designated, installed, and managed for use by the physically disabled in compliance with the Ohio Building Code, current edition, Chapter on Accessibility and the Referenced Standards therein.
2. All handicapped parking spaces shall be designated by freestanding signs as provided in the Ohio Manual of Uniform Traffic Control Devices or as approved by the City Engineer.
(3) Required Bicycle Parking
Bicycle parking is required for any development or use with six or more required vehicle parking spaces.
(b) Minimum Number of Bicycle Parking Spaces Required
1. Bicycle parking spaces shall be required as follows:
A. For residential uses, except attached and detached single-family, one space for every two dwelling units. Up to 50% of required spaces may be provided within garages for multiple-family uses provided the required reviewing body determines that the garage size and dedicated bicycle parking facilities are generally adequate to accommodate these spaces.
B. For civic/public/institutional uses, one space for every 20 required vehicle parking spaces.
C. For commercial uses, one space for every 10 required vehicle parking spaces.
2. Provided that bicycle parking is not completely eliminated, required bicycle parking may be increased or reduced by the required reviewing body when it is demonstrated that the level of bicycle activity at that location warrants a different amount.
(c) Facility Type
1. Designs of bicycle racks, docks, posts, and lockers are encouraged to be decorative, unique, and appropriate to the surrounding area. Bicycle parking design should be incorporated whenever possible into building design and coordinated with the design of street furniture when it is provided.
2. Bicycle parking racks, docks, or posts shall be designed and installed to allow a bicycle to be locked to a structure, attached to the pavement, building, or other permanent structure, with two points of contact to an individual bicycle frame. Racks, docks, and posts shall be designed to allow the bicycle frame and one or both wheels to be locked with a U-lock when used as intended.
3. Bicycle parking racks, docks or posts provided within the street right-of-way shall be of a consistent design on all streets included within a Development Plan or Site Plan Review site. Facility types, designs and locations within the street-right-of-way shall require approval by the City Engineer.
1. Required bicycle parking shall be located within a reasonable walking distance of the principal building entrances being served. Bicycle parking may be provided in and/or adjacent to open spaces where provided in accordance with §153.064. The location and design shall ensure that bicycle parking and facilities do not obstruct vehicle parking or pedestrian walkways as required by the Ohio Building Code, the Americans with Disabilities Act, and other applicable state and federal laws, policies and guidelines. Bicycle facilities and parking areas shall meet the sight visibility requirements of this Chapter.
2. Outdoor bicycle parking areas shall be located in well-lit areas in accordance with §153.065(F).
3. A pedestrian-accessible walk shall be available between the outdoor bicycle parking area and the principal building entrance. Public sidewalks may be used to meet this requirement.
4. Bicycle lockers shall be located inside or to the side or rear of the principal structure, but not within any required setback or required building zone.
5. Covered Bicycle Parking Areas
A. Bicycle parking areas are encouraged to be sheltered from natural elements by locating them inside or under principal or accessory structures, in bicycle lockers, under roof extensions, overhangs, awnings, carports or enclosures, or other similar methods.
B. If bicycle parking is covered, the cover must be permanently attached to the ground or a structure and have at least seven feet of clearance above the surface to which it is attached.
C. Covered bicycle parking areas shall be in accordance with building type requirements and are not permitted within any required setback or required building zone unless the shelter is part of the principal structure and at least five feet of clear area is available for pedestrian use.
6. Public bicycle parking provided by the City and located within the street right-of-way may be counted toward meeting the minimum bicycle parking requirement for a parcel provided that the spaces are on the same side of the street and located between the two side lot lines of the parcel. Credit for public bicycle parking spaces shall apply to parking for all uses on the parcel rather than any specific use.
7. For parcels within the Architectural Review District boundaries, public bicycle parking provided by the City and located within the street right-of-way may be counted toward meeting the minimum bicycle parking requirement provided that the spaces are on the same block face as the subject parcel.
8.On corner lots, public bicycle parking spaces on both street frontages may be counted.
9. Public bicycle parking spaces shall not be designated for exclusive use by any specific use, building or lot. (e) Installation
Bicycle parking shall be installed according to the dimensional requirements set forth by the manufacturer and the latest edition of the APBP Bicycle Parking Guidelines, or similar industry publication acceptable to the Director.
(4) Off-Street Parking Space and Aisle Dimensions
Parking spaces and maneuvering aisles shall comply with Table 153.065-B. Refer to Figure 153.065-A for a graphic depiction of these requirements.
(C) Stormwater Management
The City’s goal for stormwater management is to enact standards reflecting the most innovative, creative, environmentally effective and cost-effective practices available. Through the standards and practices incorporated in the City’s Stormwater Management Design Manual, the City encourages the use of stormwater treatment and engineering methods that allow for groundwater recharge and that manage stormwater as close to its source as possible. The use of Environmentally Sensitive Development (ESD) methods such as conservation design, smart growth, green infrastructure, integrated site design and sustainable development are practices and methods that can help achieve these goals. These practices are encouraged to be used in Dublin where suited to site and development conditions, and particularly in the Bridge Street District, consistent with the standards in the Stormwater Management Design Manual and the Principles of Walkable Urbanism provided in §153.057(D).
(2) All stormwater shall be managed as required by Chapter 53 of the Dublin City Code.
(D) Landscaping and Tree Preservation
(a) The intent of §153.065(D) is to improve the appearance of the BSD zoning districts, reduce noise and air pollution, reduce heat island impacts, protect the character and value of surrounding neighborhoods, and promote public health and safety through appropriate urban-scale landscaping of street frontages and surface parking lots. This section is also intended to ensure buffering between significantly different land uses, and that trees are preserved and replaced in a manner appropriate to urban environments.
(b) Because the BSD zoning districts reflect a more urban, mixed-use character than other areas of the city, these standards generally allow landscaping benefits to be achieved through intensities of planting or other forms of screening as an alternative to wide planted areas. Quantitative requirements for landscape materials are intended to provide minimum amounts based on the scale and intensity of development. Unless otherwise specified, these requirements should not be interpreted as requiring regular, symmetrical or standardized intervals of vegetation within landscape areas. Required landscaping should be creatively and architecturally designed to add four seasons of visual interest and preserve natural integrity, and be appropriate to the character of the surrounding area.
(a) The provisions of §§153.132 through 153.148 shall apply in the BSD zoning districts unless specifically modified or waived through the provisions of §153.065(D). Landscaping for existing sites shall be brought into compliance with the minimum requirements of this section in accordance with the provisions of §153.132(B).
(b) Each application for development or redevelopment shall include a landscape plan showing compliance with the provisions of §153.065(D). The siting of buildings shall avoid the removal of desirable trees in good or fair condition where alternatives consistent with the provisions of §153.062 are available.
(c) Protected trees, as defined in this Chapter, removed from any portion of a lot consistent with an approved Minor Project, Development Plan, or Site Plan Review shall be replaced in accordance with §153.146 except as provided by §153.065(D)(9).
(d) Existing trees which are incorporated into the landscape plan shall be protected during construction as required by §153.145.
(e) Landscape plans shall exhibit diversity in tree selection, as determined to be appropriate by the City Forester and the Director of Parks and Open Space.
(f) In all areas where landscaping is required, the surface area of any landscape bed shall be predominantly covered within four years after installation by living materials, rather than bark, mulch, gravel or other non-living materials. Areas included in rain gardens or other vegetated site features to meet stormwater management requirements are excluded from this requirement with prior approval from the Director.
(g) Areas included in rain gardens or vegetated site features created to meet stormwater management requirements may be counted towards any landscaping required by §153.065(D)(4) – (6) if landscaped to meet the requirements.
(h) All irrigation systems shall be designed, installed, and operated to minimize run-off and over-spray of irrigation water onto roadways, sidewalks, and adjacent properties, and shall be installed with rain sensors to turn the system off during rainy conditions.
(i) Shrubs and plants that exceed two and one-half feet in mature height are prohibited in required sight visibility triangles for site access points as defined in Appendix C and are prohibited in required sight visibility triangles for street intersections as defined by the City Engineer.
(j) If two or more conflicting landscape requirements apply to the same area, the one requiring the most landscaping shall apply.
(k) A registered landscape architect shall be used to prepare landscape plans required for applications for Site Plan Review.
(3) Street Trees
When a property is developed or redeveloped in any BSD zoning district the applicant shall be required to plant and maintain trees in the street right-of-way pursuant to the following requirements. No existing street trees shall be required to adhere to the following requirements unless they are required to be removed and replaced consistent with an appropriate approved application as provided in §153.066.
(a) A minimum of one tree is required per 40 linear feet of street frontage or fraction thereof. Refer to Table 153.065-D, Street Tree Spacing Requirements, for spacing based on tree size and site characteristics.
(b) Street trees shall be planted within streetscape planting zones in tree wells, tree lawns based or open planting beds based on the applicable street type design requirements. Refer to §153.061 for more information regarding street types.
(c) Street trees shall be planted in topsoil approved by the Director of Parks and Open Space or the City Forester. Structural soil or an equivalent material approved by the City Forester shall be placed under paved areas adjacent to tree wells or planting beds, parallel to and behind the curb, and connecting planting beds or tree wells to one another beneath the paved surface within the streetscape planting zone. The City Forester may require additional structural soil to extend horizontally beyond the planting zone beneath sidewalks or other paved surfaces, as necessary to ensure the long term health of street trees, depending on the planting and paving conditions within individual street types. Structural soil shall not be used in planting beds.
(d) The street tree openings shall be a minimum of five feet wide and five feet long and excavated to a minimum depth of three feet. The City Forester may require a deeper excavation based on specific tree species, site conditions, and/or conditions related to the adjacent street type.
(e) Tree wells shall be covered with a tree grate, permeable pavers (block or stone) or by plant material, where appropriate for the street type and site conditions as approved by the City Forester.
(f) Species and Size
1. Street trees shall be from the approved Urban Street Tree List for Dublin, Ohio or other species approved by the City Forester.
2. Street trees shall have a clear trunk of at least seven feet above the ground. The minimum trunk caliper measured at six inches above the ground for all street trees shall be no less than two and one-half inches. Existing trees in good or fair condition may be used to satisfy these requirements with prior approval of the City Forester.
3. Small tree species are permitted for use in planting zones where overhead utility lines exist. Small tree species may also be planted in medians, in addition to medium and/or large tree species, where medians are provided.
(g) Spacing and Location
Street trees shall be spaced as set forth in Table 153.065-F below unless modified by the City Forester based on unusual site conditions or obstructions.
(h) Maintenance and Replacement by Property Owner
The property owner shall be required to maintain the street trees for one year after the trees are planted and replace any tree which fails to survive or does not exhibit normal growth characteristics of health and vigor, as determined by the City Forester. The one-year period after the approval of the City Forester shall begin at each planting and shall recommence as trees are replaced.
(i) Prohibited Activities
1. No person shall top any tree within the public right-of-way unless specifically authorized by the City Forester. Topping is defined as the severe cutting back of limbs to stubs larger than three inches in diameter within the tree’s crown to such a degree so as to remove the normal canopy and disfigure the tree, as determined by the City Forester.
2. Unless specifically authorized by the City Forester, no person shall intentionally damage, cut, carve, transplant, or remove any tree or shrub; attach any rope, wire, nails, advertising posters, or other contrivance to any tree or shrub, allow any gaseous liquid, or solid substance which is harmful to trees or shrubs to come in contact with them; or set fire or permit fire to burn when fire or heat will injure any portion of any tree or shrub.
3. No person shall excavate any tunnels, trenches, or install a driveway or sidewalk within a radius of ten feet from the trunk of any public tree or shrub without first obtaining the prior written approval from the City Forester.
4. No person shall remove a tree or shrub from the City-owned tree lawn, streetscape planting zone or other public property without first obtaining the prior written approval of the City Forester.
5. No person shall by any type of construction reduce the size of a tree lawn or streetscape planting zone without prior written approval of the City Engineer.
6. Decorative lights, strings of lights, electrical cords or wires are not permitted to be attached to any tree for more than four consecutive months.
(j) Municipal Rights
1. The City shall have the right to plant, prune, maintain and remove trees, plants and shrubs within public rights-of-way and other public grounds as may be necessary to ensure public safety or to preserve or enhance the environmental quality and beauty of public grounds. This section shall not prohibit the planting of street trees by adjacent property owners providing that the prior written permission of the City Forester has been granted.
2. The City Forester may cause or order to be removed any tree or part of a tree that is in an unsafe condition or which by reasons of its nature is injurious to sewers, electric power lines, gas lines, water lines, or other public improvements, or is affected with any injurious fungi, insect or other pest.
3. The City Forester shall have the right to enter private property to access trees adjacent to public areas for the purposes of proper pruning, after reasonable prior written notice has been given to the property owner.
4. Wherever it is necessary to remove a tree(s) or shrub(s) from a public planting zone or other public property, the City shall endeavor to remove and replant or replace the trees or shrubs. No protected tree within the public right-of-way or on other public grounds shall be removed without prior review by the City Forester, and the trees shall only be removed if the City Forester determines there are no other means available to preserve the tree.
5. The City Forester shall have the right to cause the removal of any dead or diseased tree(s) located on private property within the city and/or cause the removal of branches of trees located on private property that overhang or impede access to public property, when those trees constitute a hazard to life and property, or harbor an epiphytotic disease which constitutes a potential threat to other trees within the city. The City Forester shall notify in writing the owners of the trees to be removed. Removal shall be done by the owners at their own expense within 60 days after the date of service of written notice, unless a longer period is agreed to in writing by the City Forester, to allow time to attempt to treat and cure a salvageable diseased tree. In the event of failure of owners to comply within 60 days, the City Forester shall notify in writing the owners of the trees of the City’s authority to remove any tree(s) and charge the cost of removal to the owner as provided by law.
(4) Perimeter Landscape Buffering
Perimeter landscape buffering is intended to provide a buffer between land uses of significantly different intensities. The buffering is intended to obscure the higher-intensity land use from view and block potential negative impacts related to noise, lighting levels, and activity through the use of denser landscape screening and/or a fence or wall visually softened by clustered plantings, creatively and architecturally designed, as appropriate to the character of the surrounding area, and approved by the required reviewing body.
(a) Perimeter landscape buffering is required:
1. When development or redevelopment in accordance with §153.062(B)(1) in any BSD zoning district abuts property in a non-BSD zoning district; or
2. With the exception of the BSD Historic Core district, when a non-residential land use is adjacent to a parcel containing only single-family detached building types (regardless of whether there is an intervening street, alley, or driveway).
(b) These requirements apply when a site subject to these requirements is developed or redeveloped in accordance with §153.062(B)(2). No existing development shall be required to install perimeter landscape buffering because of a change in the nature, character, or zoning classification of an adjacent parcel.
(c) The required perimeter landscape buffer area may be located within a utility or other easement with the prior approval of the City Engineer provided all of the landscape requirements are met.
(d) Required buffer materials must be placed on the parcel where development or redevelopment is occurring, unless both the parcel providing the buffering and the parcel being buffered are in common ownership, in which case the buffer may be provided on either or portions of both properties.
(e) Vehicles or other objects shall not overhang or otherwise intrude upon the required perimeter landscape buffer. Refer to §153.065(B)(6)(d) for curb and wheel stop requirements.
(f) Existing landscape material in good or fair condition may be used to satisfy these requirements with the prior approval of the Director.
(5) Surface Parking and Circulation Area Landscaping
All surface parking lots containing ten or more parking spaces, vehicular circulation areas for fueling/service stations, drive in/drive throughs, and other vehicular use areas shall provide the landscaping required by §153.065(D)(5).
(a) Street Frontage Screening
Surface parking lots and other vehicular use areas located within 40 feet of a public street shall either be landscaped, or a street wall shall be installed in accordance with §153.065(E)(2) along the parking lot boundary facing the street to create a visual edge along the public right-of-way. The required street frontage treatment shall be in accordance with the following:
1. Where a surface parking lot/vehicular use area is located between 20 feet and 40 feet of any street right-of-way the property owner shall install at least one deciduous tree per 40 lineal feet, or fraction thereof, of a parking lot boundary facing the public street, in addition to the street trees required by §153.065(D)(3). In addition, at least five deciduous or evergreen shrubs per 25 lineal feet, or fraction thereof, of a parking lot boundary facing the public street shall be installed, with a mature height of at least three feet. Required landscaping shall be installed within five feet of the edge of the parking lot and may be creatively clustered and architecturally designed, as appropriate to the character of the surrounding area.
2. Where a surface parking lot/vehicular use area is located within 20 feet of any street right-of-way, the property owner shall install a street wall in accordance with §153.065(E)(2) and at least five deciduous or evergreen shrubs per 25 lineal feet, or fraction thereof, of a parking lot boundary facing the public street. Trees are permitted to be installed but not required. Required landscaping may be creatively clustered and architecturally designed, as appropriate to the character of the surrounding area.
3. Where a surface parking lot/vehicular use area is located within 20 feet of a principal frontage street, the property owner shall install a masonry or wrought iron street wall in accordance with §153.065(E)(2). In addition, at least five deciduous or evergreen shrubs per 25 lineal feet, or fraction thereof, of a parking lot boundary facing the public street shall be installed. Trees are permitted to be installed but not required. Required landscaping may be creatively clustered and architecturally designed, as appropriate to the character of the surrounding area.
4. Unless otherwise approved by the required reviewing body, where a surface parking lot/vehicular use area is located within 40 feet of an alley or service street, the property owner shall install at least five deciduous or evergreen shrubs with a mature height of at least three feet, per 25 lineal feet or fraction thereof of the parking lot boundary. Required landscaping shall be installed within five feet of the edge of the parking lot and may be creatively clustered and architecturally designed, as appropriate to the character of the surrounding area.
5. Where temporary conditions are anticipated, such as developments planned in phases, the required reviewing body may consider alternative street frontage screening treatments consistent with an appropriate approved application as provided in §153.066.
6. Where the surface parking lot/vehicular use area’s proximity to the public right-of-way varies such that different treatments detailed in §153.065(D)(5)(a)1-3 are required, the street frontage screening required for the majority of that side of the parking lot/vehicular use area shall be required along the entire frontage of that same side of the parking lot/vehicular use area.
(b) Perimeter Buffering
Where a surface parking lot is located within 30 feet of a side, corner side, or rear lot line, and the adjacent property contains only single-family detached building types or is a non-BSD district (regardless of whether there is an intervening street, alley, or driveway), the property owner shall install perimeter buffering meeting the requirements of §153.065(D)(4).
(c) Interior Landscaping
