(1) The intent of this section is to provide a permissive, flexible and alternative zoning district for innovative, mixed use developments or physical design proposals only if they are designed properly and community impacts are addressed. This district allows for the combination of differing uses not normally located near each other under conventional zoning, but would permit these combinations of uses if design standards or controls are in place to make the uses compatible. In addition, it is the purpose of this district to eliminate sprawling strip commercial development by creating compatible clusters of commercial, office and residential uses while also facilitating multi-modal transportation and convenience to those residing in the development.
(2) Density, open space, infrastructure and other land use factors and impacts are significant in the review of any planned unit development. Where building intensity is increased on a particular portion of a planned unit development, then the amount of open space, retention of existing vegetation, buffer areas and new landscape, public commons, community open space and parks shall be evaluated for proportionate increase for the remainder of the planned unit development. In addition, a planned unit development may vary in height, use, organization, design, intensity, size or other features of the proposed development.
(1) Due to the unique characteristics of planned unit developments, special provisions governing the development of land for this purpose are required. Whenever there is a conflict or difference between the provisions of this regulation and those of other articles, the provisions of this section of the regulations shall prevail. Subjects not covered by this article shall be governed by the respective provisions found elsewhere in this regulation or be modified under the authority of the Planning Commission.
(2) The planned unit development (PUD) notation or zoning classification on a parcel of land does not prohibit all uses. The PUD designation is intended to allow some uses compatible to surrounding land uses, the intensity of such use or uses being subject to the review provisions of this section. PUD Districts shall originate from the Alexandria Planning Commission, City Council or private property owner and shall be approved by the City Council. If the city or Planning Commission initiates the rezoning of a parcel to PUD, the property owner will be required to submit a concept plan for action before the Planning Commission and City Council.
(3) Upon approval by the city’s Planning Commission and the City Council, a PUD may be applied in lieu of any other existing district in this order. Upon approval of this request and the concept plan from the appropriate legislative body, the official zoning map shall be annotated for the land area involved so that the district name includes the annotation “PUD”. The planned unit development district shall be approved by the Planning Commission and the City Council in the manner prescribed in Article 14 of this ordinance.
(1) In the PUD District, the number and type of permitted uses are flexible if they are compatible with adjoining land uses, the objectives of this district and harmonious with the character of the overall project. Each developer or applicant is required to define in detail the type of residential and commercial uses proposed for the site. In a primarily residential development (where at least 51% of the total acreage is proposed for residential development), commercial, office and indoor/outdoor recreational uses are permitted in the PUD District only if they appear on a neighborhood scale and are oriented toward the convenience of the commercial, office and indoor/outdoor recreational needs of the residents. Commercial, office and indoor recreational uses are allowed at a maximum of 80 square feet of commercial/office/recreational use per one residential dwelling unit or lot. There is no maximum limit on the amount of land devoted to outdoor or passive recreation (open space). However, at least 20% of the total acreage must be retained for recreational use or open space. Conversely, in a primarily commercial development (where at least 51% of the total acreage is proposed for commercial development), residential uses are allowed in the Planned Unit Development District to the extent permitted in the following table:
| |
| |
| |
Notes: ** pertains to residential uses |
(2) The developer or applicant may use those uses listed in any of the zoning classifications of this order so as to describe the type of residential, commercial or office use proposed as part of the planned unit development (PUD).
(D) Minimum size for PUD District. No PUD District shall be permitted on less than ten acres of land. However, development of a smaller tract adjacent to an existing PUD District may be permitted if the proposed development conforms to and extends the original development as if the new area had been a part of the original development.
(E) Minimal standards and amendments to the development plan.
(1) The PUD District shall be subject to the supplemental performance and development standards of this section of the zoning ordinance, unless superseded by any special requirements, conditions or other particulars imposed by the Planning Commission during the development plan application and hearing phases described in this section. Such special conditions may include but not be limited to provision governing parking, signage, common open space, lands or facilities, disposition of open land, infrastructure provisions, including any physical design and/or any other requirement found to be necessary, appropriate or desirable for the purposes of this district.
(2) Amendments to the approved development plan involving changes in the proposed uses, intensity or other elements must be submitted to the city’s Planning Commission for review and approval. If the changes are determined by the Planning Commission to be minor in nature, the Planning Commission may approve the changes and the applicant/developer may proceed with site plan review or subdivision review. If the changes are deemed to be major or substantial, then the applicant or developer shall be required to file an application before the city’s Planning Commission for a change in a previously approved development plan and a new public hearing will be scheduled in accordance with the provisions of this section of the plan.
(3) Changes requiring submittal of a new development plan and public hearing include, but are not limited to:
(a) Any increase in density or decrease of more than 25%;
(b) Re-allocation of approved land uses, and major changes in lot arrangement or building lots;
(c) Changes in the list of approved uses;
(d) Modification of the location of approved uses;
(e) Alterations in functional uses of open space, where such change conflicts with approval of the development plan;
(f) Alteration of site design requirements, such as the location and type of required landscaping, signage, building height and the like; and
(g) Modifications to proposed improvements that affect the local traffic patterns, the level of service of existing roadways, internal street system or parking area, drainage management structures, and provision of utilities.
(F) Maximum intensity and density.
(1) Intensity is a unit of measurement defining the level of activity in acres or square footage of all uses in relation to the overall size of the entire site.
(2) Density is defined as a unit of measurement involving a portion of an activity devoted to a specific use identified in acres or square footage in relation to a portion of an overall site.
(3) Generally, the maximum building intensity for PUD Districts consists of the following:
(a) Office uses: 20,000 square feet/acre; and
(b) Commercial uses: 15,000 square feet/acre.
(4) Greater intensities than these can be permitted if multi-story buildings and multi-level parking are utilized and the amount of green space can be shown to increase. Necessary infrastructure, including fire protection, must be adequately provided.
(5) Generally, the development intensity permitted in PUD Districts shall be consistent with the Future Land Use Map contained in the city’s comprehensive plan. Proposed developments should be planned in clusters and provide innovative design as outlined in the criteria and design standards contained in this section of the ordinance. Greater overall development density may be granted if the development includes dedication of appropriate developable land for public facilities and/or public recreation uses in addition to preserving developmentally sensitive areas as open space. Any increase in intensity over that recommended by the comprehensive plan must be shown by the applicant to be appropriate in terms of infrastructure, adjacent land uses and zoning, and provision of public land.
(G) Pre-application and procedure.
(1) The developer shall meet with the city’s Planning Commission staff prior to the submission of a development plan. The purpose of the meeting will be to discuss early and informally the purpose and effect of the PUD District and the criteria and standards which may apply, and to familiarize the developer with the detailed objectives of the comprehensive plan and its elements, and applicable zoning regulations.
(2) After the initial meeting with staff, the Planning Commission requires that the development plan and an application form be submitted for property located in a proposed planned unit development. The development plan may be filed with the Planning Commission by the owner(s), owner by contract (option) or lessee of property for which the planned unit development is proposed. The contents of the development plan submittal and shall follow the process and include the items as listed in § 4.19(C), (D) and (E).
(3) Approval of the development plan shall not be construed to endorse engineering feasibility or plan elements that do not meet the development standards of this ordinance or subdivision regulations unless an exception is specifically granted through the review and approval of the development plan. The Planning Commission may seek assistance in making its recommendation from any appropriate source.
(4) Upon receipt of an application for approval of the Planned Unit Development District or development plan, the Planning Commission shall hold at least one public hearing, within 30 days of receipt of the application, after notice as required for amendment under KRS Chapter 424 and as stated in Article 14 of this ordinance.
(H) Criteria for approval. No application or development plan shall be approved for a Planned Unit Development District under the provisions of these regulations unless each district and application fulfills the following standards.
(1) The planned unit development shall generally conform to the adopted comprehensive plan with respect to type, character and intensity of use and impact on public facilities, services and road network. The intensity of the planned unit development, in particular, should be generally consistent with the Future Land Use Map and development policies for the area. Deviation from the comprehensive plan is dependent upon whether the site is part of an urban service area for public infrastructure and upon the provision of public facilities, services and roads by the applicant to mitigate the impact of the proposed development on these infrastructure systems.
(2) The planned unit development shall efficiently utilize the site, and shall protect and preserve the scenic assets and natural features by incorporating existing trees, streams and topographic features into the site design. The development shall include the provision that designated natural areas, scenic areas (views/vistas) and developmentally sensitive areas as identified in the comprehensive plan will constitute permanent open space or be dedicated to public or semi-public organizations for recreational use. At least 20% of the total site acreage shall be dedicated as recreation or open space.
(3) The planned unit development provides interconnected open spaces, recreational areas and opportunities for multi-modal transportation (i.e., sidewalks, walking trails, bicycle trails and the like) as identified in the city’s comprehensive plan.
(4) Each developer or applicant is required to define in detail the type of residential and commercial uses proposed for the site. Commercial, office and indoor/outdoor recreational uses are permitted in the PUD District only if they appear on a neighborhood scale and are oriented toward conveniently serving the commercial, office and indoor/outdoor recreational needs of the residents.
(5) Although the PUD District encourages a variety of housing types and mixture of densities within one development, housing shall be clustered by density type. In no case should there be a mixing of densities within a residential cluster. For example, single-family homes shall not be sited directly adjacent to duplexes, apartment complexes and the like within the same cluster.
(6) Where appropriate, the planned unit development shall include developable land that is unbuilt and available for purchase or donation to public agencies for recreation or public facility building sites. This provision of land can constitute one reason for increased development densities on portions of the site or even increased overall development intensity in relation to the comprehensive plan; provided, other public facilities and services are adequately provided.
(7) The planned unit development shall not hinder nor deter development or surrounding undeveloped properties in accordance with the adopted comprehensive plan. Where different land uses or development densities exist adjacent to or within the site, substantial buffers and transitions between the PUD and the adjacent use must be provided.
(8) The planned unit development shall be located in an area in which transportation, police and fire protection, other public facilities and utilities, including sanitary sewerage are provided, or will be available and adequate for the uses proposed. The applicant shall make provision for such facilities or utilities which are not presently available or shall construct such facilities for the eventual connection into a public system.
(9) The development will not have an adverse impact on the surrounding area and will be harmonious and compatible with adjacent uses. The term
COMPATIBILITY refers to, but is not limited to, size, scale, mass, architectural design and landscaping.
(10) The extent to which the proposed planned unit development meets the requirements, standards and stated purpose of the PUD regulations and design criteria.
(11) The proposal fully complies with the minimum requirements contained in this ordinance and subdivision regulations.
(12) The proposal must not adversely affect the public health, safety and welfare. This flexible approach to planned unit development is intended to provide an opportunity and incentive to the developer to achieve excellence in physical, social and economic planning. To be approved, the property owner or developer must demonstrate achievement of the above objectives and standards. In addition, a property owner or developer’s request for a planned unit development is assessed in terms of its impact on the existing conditions of the surrounding land uses, utility systems, road network and public facilities and services. The applicant must provide this information to the Planning Commission in written and/or graphic form as part of the development plan submittal. In summary, it is the burden of proof for the property owner or developer to present why the concept plan is unique and requires the special consideration that can only be fulfilled by the Planned Unit Development District. Equally important is that the property in question could be unique with certain qualities and/or amenities that warrant the special consideration of the Planned Unit Development District. Proposed developments that cannot be shown to meet these standards may be more appropriately developed under conventional zoning districts.
(I) Design standards. The proposed uses and development plan in each Planned Unit Development District shall be assessed in terms of the design standards contained in this section. Each applicant or developer is required to demonstrate how the proposed development plan fulfills the following design standards in a written or graphic manner.
(1) Height. The height of any structure shall be compatible with the existing buildings in the area, and proposed structures within the project site.
(2) Placement or location of buildings. Consideration should be given to the most appropriate location of buildings based upon access and direct visibility. The location of any building should not interrupt a continuous visual pattern from public view or a public street. Building location should be planned to accomplish a transition with the landscaped, pedestrian and parking areas. Building setbacks can vary in order to allow appropriate building location. The setback on the perimeter of the Planned Unit Development District shall be large enough to protect the privacy and amenity of adjoining uses both existing and anticipated.
(3) Preliminary building design or architecture. Buildings should be designed in the same architectural style as if part of a large commercial, residential or office center. Individual buildings not part of the larger development should be compatible with surrounding structures. All structures shall have consistent design treatment on all facades. The unified architectural style or building design shall also apply to materials, colors, roof types and entrances, and shall include traditional, regionally influenced architectural forms and elements, and shall allow variations within it. The architectural theme shall also relate to existing structures on the project site and adjacent sites, especially if such existing structures are historic. The use of architectural guidelines is required for multi-phased projects.
(4) Scale. Consideration shall be given to the scale of each building and architectural detail, which relates to the size of an individual and the natural environment. In general, planned unit developments shall have a pedestrian scale and orientation. In rendering this decision, emphasis shall be placed on mass and how it relates to open space.
(5) Elevation. The elevation of any site or structure should be determined by the grade of any existing or proposed public road. Consideration should be given to the relationship between the width and height of the front, side and rear elevations of any building from a public road. Exposed foundations from a public street should be minimized.
(6) Historic and prehistoric features. Historic features on the project site shall be retained, utilized and incorporated into the overall project design if physically and economically feasible.
(7) Streetscape. The streetscape of a PUD should be designed in detail specifying lighting, placement of street trees and street furniture (benches, wastebaskets and the like).
(8) Focal point. Any opportunity for a strong, central focus should be studied and developed. These central places are usually a key to establishing community identity.
(9) Paved surfaces. Emphasis should be placed on preserving at a reasonable rate the amount of open space. The interior road system, sidewalk system, and parking lot should be designed with this in mind. Paved surface refers to cement, brick pavement, asphalt, cobblestone or other similar type surfaces. Parking areas should be treated with decorative elements, fence or wall extensions, plantings and berms as other means to screen parking areas from public view or soften their visual impact. Although it is recommended that parking areas be dispersed throughout the site and located to the rear of structures, all large parking lots shall be designed with landscaped islands. Parking lots and driveway aisles should be either asphalt or concrete. Landscaped entrances with trees and bushes should be encouraged near the entrances of the development.
(10) Fences, walls and landscaped berms. Consideration should be given to brick walls, fences and landscaped berms, which would produce a continuous cohesive wall of enclosure on a lot line or adjacent to a road. These fences and walls shall be designed and maintained in relationship with the character of the surrounding land uses and structures.
(11) Landscaping. Consideration should be given to the predominance of a quality and quantity of landscaping and an emphasis shall be given to streetscape areas, buffer zones and the provision of significant landscaping (in terms of the size of landscaped areas, and quantity and quality of landscape materials) within the proposed developed portions of the site. Landscaping details will be evaluated on the entire site and surrounding any proposed structure and shall be reviewed in relation to adjacent properties. A special attempt should be made to preserve the existing vegetation and scenic areas, if any and encourage additional open space for the public’s benefit. Existing topography, significant tree cover and watercourses/bodies shall be largely preserved and incorporated into the project design, where appropriate, and should be consistent with the remainder of these regulations. Plantings should be used to soften the impact of parking and loading areas. Plant material should be selected on the basis of texture and color and for its ultimate growth to provide a visual screen for the public. Scenic views and vistas as identified in the city’s comprehensive plan shall be remain unblocked or uninterrupted, particularly as seen from public thoroughfares. The use of landscape design guidelines is required for multi-phased projects.
(12) Grading. All mature vegetation, prime agricultural soils, floodplains, wetlands and steep slopes shall be protected from excessive clearing, grading, filling and construction activities. In addition, new construction on prominent hilltops or ridges is discouraged.
(13) Open space and recreational uses. Planned unit developments shall make a provision for preserving open space and devoting an appropriate portion of the site to meet the recreational needs of the residential population. A minimum of 20% of the total site acreage shall be retained as a recreation area or common open space and dedicated to a public or private entity for operation and maintenance. Such open space shall be physically situated so as to be readily accessible, available to and useable by all residents of the PUD. These spaces may be provided in the form of parks, plazas, arcades, commons, trails, sports courts or other athletic and recreational areas, outdoor areas for the display of sculptural elements and the like. Land reservations for community facilities may be considered in lieu of useable open space. Recreation area and open space areas identified in the city’s comprehensive plan shall be utilized for recreational purposes or preserved to the greatest extent possible.
(14) Signage. Signage should be designed to protect the visual order of any site and to minimize the impact of adjacent properties. Consideration should be given to the number, location, size and height of any building mounted sign or freestanding sign. A consistent signage theme shall be provided within the planned unit development. Building mounted signs shall be the predominant signage on the project site. Freestanding signs shall be monument style and limited in number, size and height. The use of signage design guidelines is required for multi-phased projects.
(15) Utilities. All utility service lines to the building and possible main lines to or within the site shall be located and installed underground. Alternatives may be possible if this requirement is economically infeasible.
(16) Detention/retention ponds or lakes. Large detention/retention ponds or lakes should be discouraged in the front yard or in an area viewed from a public street if not used for both storm water management and aesthetic purposes. Smaller detention/retention ponds or lakes appropriately designed and landscaped should be encouraged and distributed throughout the site and may appear in the front yard or in an area viewed from a public street. Surface drainage and flood water retention shall be planned to not adversely impact the adjoining properties.
(17) Transportation design. Principal vehicular access shall be from major streets and access points shall be designed to encourage smooth traffic flow with controlled turning movements and minimum hazards to vehicular or pedestrian traffic. Maximum separation of vehicular traffic on major roads from pedestrian and recreational areas shall occur. The provision of transportation connections (street connections, pedestrian paths and sidewalks, bicycle facilities) shall be provided in all planned unit developments unless physically unfeasible or undesirable due to land use characteristics. Rural roadside character shall be preserved by avoiding development fronting directly into existing public roads. Buffer zones shall be established along scenic corridors and roadways.
(18) Multi-modal transportation system. Planned unit developments shall incorporate multi-modal transportation elements in the development, depending on the foreseeable needs of future residents and users of the site and the relationship of the project site to the community at large. Such multi-modal elements may include provisions for mass transit stops or stations, car pooling lots, pedestrian and bicycle paths and lanes, bicycle parking areas and the like. The proposed pedestrian circulation system should be designed to assure that pedestrians can walk safely and easily on the site, between properties and activities or special features within the open space system. All roadside footpaths should connect with off road trails, which in turn should link with potential open space on adjoining undeveloped parcels (or with existing open space on adjoining developed parcels, where applicable). Sidewalks, walking and bicycle trails identified in the city’s comprehensive plan must be incorporated into the overall design of the project.
(19) Location of land uses. Land uses shall be located primarily for convenience to the area and compatibility with the adjoining land uses. If conflicting land uses are intended to be located near each other, measures shall be taken to mitigate the impact of the uses upon each other.
(J) Findings necessary for a zoning map amendment or development plan in a Planned Unit Development District. Each application shall conform to the criteria in Article 14 of this ordinance in presenting the basis for granting a zoning map amendment or approval of a development plan in a Planned Unit Development District. In addition, each application shall be in conformance with the standards and requirements stated in this section of the ordinance.
(K) Action by the Planning Commission and City Council.
(1) Within 90 days of receipt of an application for a development plan and after the public hearing required in this section has been conducted, the Planning Commission shall determine whether the development plan is consistent with the intent, purpose, requirements and standards or this regulation; whether the proposed development advances the general welfare of the community and neighborhood, and whether the benefits, combination of various land uses, innovation of physical design and the inter-relationship with the land uses in the surrounding area justify any deviation from standard district regulations as mentioned in the objectives section of this regulation.
(2) Final action for approval in principle, as described in Article 14 of this ordinance, or denial of a Planned Unit Development Zoning District shall be made by the City Council. After recommendation of the city’s Planning Commission all materials constituting the record and recommendations of the Planning Commission shall be transmitted to the City Council. Within 90 days from the Commission’s recommendation, the City Council may take action to approve or deny the PUD zoning map designation. Approval shall be by ordinance. When a PUD zoning designation is approved, the subject property so zoned shall be respectively designated as “PUD” on the official zoning map of the city. Upon approval of a map amendment to utilize either classification, the notation “CD” shall be placed on the official zoning map as well. A certificate of land use restriction (CLUR) giving notice of the approval for PUD Zoning District designation shall be filed within 30 days of final action as explained in § 13.16 of this ordinance. If disapproved, the City Council shall state the reasons for disapproval.
(L) Subsequent review after development plan approval. After the city’s Planning Commission has approved a development plan in a PUD District, the applicant or property owner may proceed through the subdivision review or site plan review approval process. Subdivision review requirements can be found in the city’s subdivision regulations and site plan review requirements are outlined in this ordinance.
(M) Ownership and maintenance of open space. Different ownership and management options apply to permanently protected open space created through the development process. The open space shall remain undivided and may be owned and managed by a homeowner’s association, the city or a recognized land trust or conservancy. A public land dedication (not exceeding 10% of the total parcel size) may be required by the city in order to facilitate the connections of pedestrian ways or open or scenic views and vistas as identified in the city’s comprehensive plan. A narrative describing ownership, use and maintenance responsibilities shall be submitted for all common and public improvements, utilities and open spaces.
(N) Ownership standards. Common open space within a development shall be owned, administered and maintained by any of the following methods, either individually or in combination, and is subject to approval by the Planning Commission.
(a) The city shall have the first and last offer of dedication of undivided open space in the event said land is to be conveyed. Dedication shall take the form of fee simple ownership. The city may, but not be required to, accept undivided open space; provided:
1. Such land is accessible to the residents of the city;
2. There is no cost of acquisition other than any costs incidental to the transfer of ownership such as title insurance; and
3. The city agrees to and has access to maintain such lands.
(b) Where the city accepts dedication of common space that contains improvements, the city may require the posting of financial security to ensure structural integrity of said improvements as well as the functioning of said improvements for a term not to exceed 18 months from the date of acceptance of dedication. The amount of financial security shall not exceed 15% of the actual cost of installation of said improvements.
(2) Homeowner’s association. The undivided open space and associated facilities may be held in common ownership by a homeowner’s association. The association shall be formed and operated under the following provisions.
(a) The developer shall provide a description of the association including its bylaws and methods for maintaining the open space.
(b) The association shall be organized by the developer and shall be operated with a financial subsidy from the developer, before the sale of any lots within the development.
(c) Membership in the association is automatic (mandatory) for all purchasers of homes therein and their successors. The conditions and timing of transferring control of the association from the developer to homeowners shall be identified.
(d) The association shall be responsible for maintenance of insurance and taxes on undivided open space, enforceable by liens placed by the city on the association. The association may place liens on homes or house lots of its members who fail to pay their association dues in a timely manner. Such liens may require the imposition of penalty interest charges.
(e) The members of the association shall share equitably the costs of maintaining and developing such undivided open space. Shares shall be defined within the association bylaws.
(f) In the event of the proposed transfer, within the methods permitted in these regulations, of undivided open space land by the homeowner’s association, or of the assumption of maintenance or undivided open space land by the city, notice of such action shall be given to all property owners within the development.
(g) The association shall have or hire adequate staff to administer common facilities and properly (and continually) maintain the undivided open space.
(h) The homeowner’s association may lease open space lands to any other qualified person, or corporation, for operation and maintenance of open space lands, but such a lease agreement shall provide:
1. The residents of the development shall, at all times, have access to the open space lands contained therein (except croplands during the growing season);
2. The undivided open space to be leased shall be maintained for the purposes set forth in this ordinance; and
3. The operation of open space facilities may be for the benefit of the residents only, or may open to the residents of the city, at the election of the developer and/or homeowner’s association, as the case may be.
(i) The lease shall be subject to the approval of the city and any transfer or assignment of the lease shall be further subject to the approval of the city. Lease agreements so entered upon shall be recorded in the Campbell County Clerk’s office within 30 days of their execution and a copy of the recorded lease shall be filed with the city.
(O) Transfer of easements to a private conservation organization. With the permission of the city, an owner may transfer easements to a private, non-profit organization, among whose purposes it is to conserve open space and/or natural resources; provided that:
(1) The organization is acceptable to the city, and is a bona fide conservation organization with perpetual existence;
(2) The conveyance contains appropriate provisions for proper reverter or retransfer in the event that the organization becomes unwilling or unable to continue carrying out its functions; and
(3) A maintenance agreement acceptable to the city is entered into by the developer and the organization.
(P) Maintenance standards.
(1) (a) The ultimate owner of the open space (typically a homeowner’s association) shall be responsible for raising all monies required for operations, maintenance or physical improvements to the open space through annual dues, special assessments and the like.
(b) The homeowner’s association shall be authorized under its bylaws to place liens on the property of the residents who fall delinquent in payment of such dues, assessments and the like.
(2) In the event that the association or any successor organization shall, at any time after establishment of a development containing undivided open space, fail to maintain the undivided open space in reasonable order and condition in accordance with the development plan, the city may serve written notice upon the owner of record, setting forth the manner in which the owner of record has failed to maintain the undivided open space in a reasonable condition.
(3) Failure to adequately maintain the undivided open space in reasonable order and condition constitutes a violation of this regulation. The city is hereby authorized to give notice, by personal service or by U.S. mail, to the owner or occupant, as the case may be, of any violation, directing the owner to remedy the same within 30 working days.
(4) Should any bill or bills for maintenance of undivided open space by the city be unpaid by November 1 of each year, a late fee of 15% shall be added to such bills and a lien shall be filed against the premises in the same manner as other municipal claims.
