CHN College Hill Neighborhood Overlay Zoning District. In the College Hill Neighborhood Overlay Zoning District, the following provisions, regulations and restrictions shall apply: (1) Boundaries. The College Hill Neighborhood Overlay Zoning District (CHN district) boundaries are shown in the College Hill neighborhood master plan and legally described in attachment A. (Said attachment is not set out at length herein but is on file in the office of the city planner.) (2) Purpose and intent. a. The purpose of the College Hill Neighborhood Overlay Zoning District is to regulate development and land uses within the College Hill neighborhood and to provide guidance for building and site design standards, maintenance and development of the residential and business districts in a manner that complements the University of Northern Iowa campus, promotes community vitality and safety and strengthens commercial enterprise. New structures, including certain types of fences, certain modifications to existing structures and certain site improvements and site maintenance shall conform to this section. b. The provisions of this section shall apply in addition to any other zoning district regulations and requirements in which the land may be classified. In the case of conflict, the most restrictive provisions shall govern unless otherwise expressly provided in this section. (3) Definitions. The following words, terms and phrases, when used in this section, shall have the meanings ascribed to them in this subsection, except where the context clearly indicates a different meaning: Bedroom means a room unit intended for sleeping purposes containing at least 70 square feet of floor space for each occupant. Neither closets nor any part of a room where the ceiling height is less than five feet shall be considered when computing floor area. Change in use means and include residential uses changed from single-unit to two-unit or two-unit to multi-unit or to any increase in residential intensity within a structure (i.e., change from duplex to fraternity house). The term "change in use" shall also apply to changes in use classifications (i.e., residential to commercial). Fraternity/sorority means residential facilities provided for college students and sponsored by university affiliated student associations. Such facilities may contain individual or common sleeping areas and bathroom facilities but shall provide common kitchen, dining, and lounging areas. Such facilities may contain more than one unit. Greenway means open landscaped area maintained for floodplain protection, stormwater management and public access. Such area may contain pedestrian walkways or bicycle pathways but is not intended for regular or seasonal usage by motorized recreational vehicles. Landscaped area means an area not subject to vehicular traffic, which consists of living landscape material including grass, trees and shrubbery. Lot split, property transfer means not a subdivision plat where a new lot is being created; includes any transfer of small segments of property or premises between two abutting properties, whether commonly owned or owned by separate parties, where one property (the "sending property") is dedicating or deeding additional land to another abutting property (the "receiving property"). Mixed-Use Building means a building designed for occupancy by a minimum of two different uses. Uses generating visitor or customer traffic (such as retail, restaurants, personal services) are typically located on the ground floor facing the street, whereas uses generating limited pedestrian activity (such as office or residential uses) are typically located on upper floors or behind street-fronting commercial uses. Neighborhood character. The College Hill neighborhood area is one of the city's oldest and most densely populated neighborhoods. As the University of Northern Iowa has grown the original single-unit residential neighborhood surrounding the campus area has been transformed into a mixture of single-unit, duplex and multiple unit dwelling units along with a few institutional uses and other university-related uses such as fraternities and sorority houses. These various uses are contained in a variety of underlying zoning districts (i.e., R-2, R-3, R-4 Residential and C-3 Commercial Districts). Architectural styles vary significantly among existing building structures while differing land uses and building types are permitted in different zoning districts. When references are made in this article to preservation of neighborhood character, uniformity of building scale, size, bulk and unusual or widely varying appearance are of primary concern regardless of the nature of the proposed building use. New construction, including significant improvements to existing structures, shall be of a character that respects and complements existing neighborhood development. The following variables or criteria shall be used in determining whether a newly proposed construction or building renovation is in keeping with the character of the neighborhood: 1. Overall bulk/size of the building; 2. Overall height of the building; 3. Number of proposed dwelling units in comparison to surrounding properties; 4. Lot density (lot area divided by number of dwelling units); 5. Off-street parking provision; 6. Architectural compatibility with surrounding buildings. Parking area means that portion of a parcel of land that is improved and designated or commonly used for the parking of one or more motor vehicles. Parking lot means that area improved and designated or commonly used for the parking of three or more vehicles. Parking space (also parking stall) means an area measuring at least nine feet wide and 19 feet long for all commercial, institutional or manufacturing uses or eight feet wide and 18 feet long for residential uses only, connected to a public street or alley by a driveway not less than ten feet wide, and so arranged as to permit ingress and egress of motor vehicles without moving any other vehicle parked adjacent to the parking space. Premises means a lot, plot or parcel of land including all structures thereon. Residential Building: Any building that is designed and/or used exclusively for residential purposes, but not including a tent, cabin or travel trailer. Residential conversion means the alteration or modification of a residential structure that will result in an increase in the number of rooming units or dwelling units within the residential structure. The addition or creation of additional rooms within an existing rooming unit or dwelling unit does not constitute a residential conversion. Structural alteration means any alteration, exterior or interior that alters the exterior dimension of the structure. This provision shall apply to residential, commercial and institutional uses including churches or religious institutions. Substantial improvement means any new construction within the district or any renovation of an existing structure, including the following: 1. Any increase in floor area or increased external dimension of a residential or commercial structure. Additional bedrooms proposed in an existing duplex or multi-unit residence shall be considered a substantial improvement. Bedroom additions to single-unit residences shall not be considered to be a substantial improvement. 2. Any modification of the exterior appearance of the structure by virtue of adding or removing exterior windows or doors. Repair or replacement of existing windows or doors which does not result in any change in the size, number or location of said windows and doors shall not be considered to be a substantial improvement. 3. Any structural alteration that increases the number of bedrooms or dwelling units. Interior room additions, including bedroom additions, may be made to single-unit residential structures without requiring additional on-site parking. 4. All facade improvements, changes, alterations, modifications or replacement of existing facade materials on residential or commercial structures. Routine repair and replacement of existing siding materials with the same or similar siding materials on existing structures shall be exempt from these regulations. 5. Any new, modified or replacement awnings, signs or similar projections over public sidewalk areas. 6. Any increase or decrease in existing building height and/or alteration of existing roof pitch or appearance. Routine repair or replacement of existing roof materials that do not materially change or affect the appearance, shape or configuration of the existing roof shall not be considered a substantial improvement. 7. Any construction of a detached accessory structure measuring more than 300 square feet in base floor area for a residential or commercial principal use. 8. Any increase in area of any existing parking area or parking lot or any new construction of a parking area or parking lot, which existing or new parking area or parking lot contains or is designed to potentially accommodate a total of three or more parking stalls. 9. Any proposed property boundary fence, which utilizes unusual fencing materials such as stones, concrete blocks, logs, steel beams or similar types of atypical or unusual fence materials. Standard chain-link fences, wooden or vinyl privacy fences shall be exempt from these provisions. 10. Demolition and removal of an entire residential, commercial or institutional structure on a property shall not be considered a substantial improvement. (4) Administrative review. a. Applicability. The provisions of this section shall constitute the requirements for all premises and properties that lie within the boundaries of the College Hill neighborhood overlay zoning district. This section and the requirements stated herein shall apply to all new construction, change in use, structural alterations, substantial improvements or site improvements including: 1. Any substantial improvement to any residential, commercial or institutional structure, including churches. 2. Any new construction, change in use, residential conversion or structural alteration, as defined herein, for any structure. 3. Any new building structure including single-unit residences. b. Emergency repairs. In the case of emergency repairs required as the result of unanticipated building or facade damages due to events such as fire, vandalism, flooding or weather-related damages, site plan review by the planning and zoning commission and the city council will not be required for completion of said emergency repairs, provided that the extent of damages and cost of said repairs are less than 50 percent of the value of the structure. However, said emergency repairs along with cost estimates related to the extent of building structural damages shall be verified by the city planner in conjunction with the city building inspector. Said emergency repairs, to the extent possible, shall repair and re-establish the original appearance of the structure. In the event that said emergency repairs result in dramatic alteration of the exterior appearance of the structure as determined by the city planner, the owner of the property shall make permanent repairs or renovations that re-establish the original appearance of the structure with respect to facade features, window and door sizes, locations and appearances of said windows and doors within six months following completion of said emergency repairs. Said emergency repairs shall not alter the number, size or configuration of pre-existing rooms, bedrooms or dwelling units within the structure. c. Submittal requirements. Applicants for any new construction, change in use, structural alteration, facade alteration, residential conversion, substantial improvement, parking lot construction or building enlargement shall submit to the city planning division an application accompanied by such additional information and documentation as shall be deemed appropriate by the city planner in order for the planning division to properly review the application. The required application for any project may include one or more of the following elements depending upon the nature of the application proposal. Some applications will require submittal of more information than other types of applications. The city planner will advise the applicant which of these items need to be submitted with each application with the goal of providing sufficient information so that decision makers can make an informed decision on each application. 1. Written description of building proposal, whether a new structure, facade improvement, parking lot improvement, building addition, etc. The name and address of the property owner and property developer (if different) must be provided; 2. Building floor plans; 3. Building materials; 4. Dimensions of existing and proposed exterior building "footprint"; 5. Facade details/exterior rendering of the structure being modified, description of proposed building design elements including, but not limited to, building height, roof design, number and location of doors and windows and other typical facade details; 6. Property boundaries, existing and proposed building setbacks; 7. Parking lot location, setbacks, parking stall locations and dimensions along with parking lot screening details; 8. Lot area and lot width measurements with explanation if any portion of an adjacent lot or property is being transferred to the property under consideration; 9. Open green space areas and proposed landscaping details with schedule for planting new landscaping materials; 10. Trash dumpster/trash disposal areas; 11. Stormwater detention/management plans. Following submittal of the appropriate application materials as determined by the city planner, said application materials shall be reviewed by the city planning and zoning commission and the city council to determine if the submittal meets all chapter requirements and conforms to the standards of the comprehensive plan, recognized principles of civic design, land use planning and landscape architecture. The commission may recommend and the city council may approve the application as submitted, may deny the application, or may require the applicant to modify, alter, adjust or amend the application as deemed necessary to the end that it preserves the intent and purpose of this section to promote the public health, safety and general welfare. (5) District requirements and criteria for review. a. Minimum on-site parking requirements. The following standards shall apply in the College Hill Neighborhood Overlay District and shall govern if different from the requirements listed in Section 26-220, Off-street parking spaces. 1. Single-unit Dwelling: Two parking stalls per dwelling. 2. Single-unit Dwelling, renter-occupied: Two parking stalls per dwelling unit plus one additional parking stall for each bedroom in excess of two bedrooms. 3. Two-unit Dwelling: Two stalls per dwelling units plus one additional stall for each bedroom in each dwelling unit in excess of two bedrooms. 4. Multiple Dwelling: Two stalls per dwelling unit plus one additional stall for each bedroom in excess of two bedrooms. One additional stall shall be provided for every five units in excess of five units for visitor parking. 5. Non-residential uses in the C-3 District: No parking required. 6. Dwelling units within Mixed-Use Buildings in the C-3 District: One parking stall per bedroom, but not less than one stall per dwelling unit, except as follows. For mixed-use buildings constructed prior to January 1, 2019, parking is not required for existing dwelling units. In addition, for mixed-use and commercial buildings constructed prior to January 1, 2019, parking is not required for upper floor space that is converted to residential use. 7. Dwelling units within Mixed-Use Buildings in zones other than the C-3 District: Two stalls per dwelling unit plus one additional stall for each bedroom in excess of two bedrooms. One additional stall shall be provided for every five units in excess of five units for visitor parking. 8. Boardinghouse/roominghouse: Five stalls plus one stall for every guest room in excess of four guest rooms. 9. Fraternity/sorority: Five parking stalls plus one stall for every two residents in excess of four residents. 10. Where fractional spaces result, the number required shall be the next higher whole number. 11. Bicycle accommodations: All new multi-unit residential facilities are encouraged to provide for the establishment of bicycle racks of a size appropriate for the anticipated residential occupancy of the facility. A general suggested bike parking standard is two bike stalls per residential unit. For commercial projects, if lot area is available, bike racks are encouraged to be installed in conjunction with the commercial project. b. Parking lot standards. 1. All newly constructed or expanded parking lots (three or more parking stalls) shall be hard surfaced with concrete or asphalt, provided with a continuous curb, be set back a minimum five feet from adjacent property lines or public right-ofway with the exception of alleyways, in which case a three foot permeable setback will be required, and otherwise conform to all parking guidelines as specified in this section and in section 26-220. Alternative parking lot surfaces may be considered to the extent that such surfaces provide adequate stormwater absorption rates, subject to city engineering review and approval, while providing an acceptable surface material and finished appearance. Gravel or crushed asphalt parking lots will not be permitted. How- ever, other types of ecologically sensitive parking lot designs will be encouraged and evaluated on a case-by-case basis. 2. Landscaping in parking lots shall be classified as either internal or peripheral. The following coverage requirements shall pertain to each classification: (i) Peripheral landscaping. All parking lots containing three or more parking spaces shall provide peripheral landscaping. Peripheral landscaping shall consist of a landscaped strip not less than five feet in width, exclusive of vehicular obstruction, and shall be located between the parking area and the abutting property lines. One tree for each 25 lineal feet of such landscaping barrier or fractional part thereof shall be planted in the landscaping strip. At least one tree shall be planted for every parking lot (such as a three-stall parking lot) regardless of the lineal feet calculation. In addition to tree plantings, the perimeter of the parking lot shall be screened with shrubbery or similar plantings at least three-feet in height as measured from the finished grade of the parking lot at the time of planting for purposes of vehicular screening. The vegetative screen should present a continuous, effective visual screen adjacent to the parking lot for purposes of partially obscuring vehicles and also deflecting glare from headlights. If landscaped berms are utilized, the berm and vegetative screening must achieve at least a 3-foot tall screen at the time of installation as measured from the grade of the finished parking lot. Each such planting area shall be landscaped with grass, ground cover or other landscape material excluding paving, gravel, crushed asphalt or similar materials, in addition to the required trees, shrubbery, hedges or other planting material. Existing landscaping upon abutting property shall not be used to satisfy the requirements for said parking lot screening requirements unless the abutting land use is a parking lot. (ii) Exceptions. A. Peripheral landscaping shall not be required for single-unit or two-unit residential structures where the primary parking area is designed around a standard front entrance driveway and/or attached or detached residential garage. However, if an open surface parking lot containing three or more parking stalls is established in the rear yard of a two-unit residential structure, the perimeter landscaping/ screening requirements as specified herein shall apply. B. Peripheral landscaping shall not be required for parking lots that are established behind building structures where the parking lots do not have any public street or alley frontage or is not adjacent to any open properties such as private yards, parks or similar open areas. Examples of such a parking lot would be one designed with a multiple unit apartment facility where the parking lot is encircled with building structures within the project site and where the parking lot is completely obscured from public view by building structures. C. Underground or under-building parking lots. D. Aboveground parking ramps shall provide perimeter screening as specified herein around the ground level perimeter of the parking structure. (iii) Internal landscaping. All parking lots measuring 21 parking stalls or more shall be required to landscape the interior of such parking lot. At least one overstory tree shall be established for every 21 parking stalls. Each tree shall be provided sufficient open planting area necessary to sustain full growth of the tree. Not less than five percent of the proposed paved area of the interior of the parking lot shall be provided as open space, excluding the tree planting areas. These additional open space areas must be planted with bushes, grasses or similar vegetative materials. Each separate open green space area shall contain a minimum of 40 square feet and shall have a minimum width dimension of a least five feet. (iv) Exceptions. Internal landscaping shall not be required for vehicular storage lots, trucking/warehousing lots or for automobile sales lots. However, perimeter landscaping/screening provisions, as specified herein, shall be required for all such parking areas when they are installed or enlarged in area. (v) Parking garages or parking ramps. All such facilities where one or more levels are established for parking either below ground or above ground and where structural walls provide for general screening of parked vehicles, internal landscaping shall not be provided. (vi) Open green space; landscape areas. It is the intent of this regulation that in parking development sites open green space and landscape areas should be distributed throughout the parking development site rather than isolated in one area or around the perimeter of the parking lot. Trees and shrubs planted within parking areas shall be protected by concrete curbs and provide adequate permeable surface area to promote growth and full maturity of said vegetation. 3. Parking stalls must provide a minimum separation of four feet from the exterior walls of any principal structure on the property as measured from the vehicle (including vehicular overhang) to the nearest wall of the structure. No vehicular parking stall shall be so oriented or positioned as to block or obstruct any point of egress from a structure, including doorways or egress windows. 4. No portion of required front or side yards in any residential (R) zoning district shall be used for the establishment of any parking space, parking area, or parking lot, except for those driveways serving a single- or two-unit residence. For all other uses, a single driveway no more than 18 feet in width may be established across the required front and side yards, provided that side yard driveway setbacks are observed, as an access to designated rear yard parking areas, unless said lot is dedicated entirely to a parking lot, in which case a wider driveway access will be allowed across the required yard area to access said parking lot. 5. When a driveway or access off a public street no longer serves its original purpose as access to a garage or parking lot due to redevelopment of the property or is replaced with an alternative parking lot or parking arrangement with an alternate route of access, the original driveway access shall be re-curbed by the owner at the owner's expense and the parking/ driveway area shall be returned to open green space with grass plantings or other similar landscaping materials. 6. Routine maintenance of existing parking areas and parking lots, including resurfacing of said areas with similar materials or with hard surfacing will be permitted without requiring review by the planning and zoning commission and city council, provided that no increase in area of said existing parking area or parking lot, or any new construction of a parking area or parking lot, which existing or new parking area or parking lot contains or is designed to potentially accommodate a total of three or more parking stalls, occurs. Any newly paved or hard surfaced parking lot, excluding those existing hard surface parking lots that are merely being resurfaced, must satisfy minimum required setbacks from the property line or alley and must provide a continuous curb around the perimeter of said improved parking lot. Hard surfacing of any existing unpaved parking area or parking lot will require an evaluation by the city engineering division regarding increased stormwater runoff/possible stormwater detention. c. Stormwater drainage. 1. Stormwater detention requirements as outlined in section 24-338 and in section 26-94 shall apply to all newly developed parking lots and new building uses. In addition, said requirements shall apply to any existing parking lot that is resurfaced, reconstructed or enlarged subject to review by the city engineer. In those cases where no municipal storm sewer is readily available to serve a particular property or development site, the use of the property will be limited. The maximum allowable use that shall be permitted on any particular property or development site which is not served by a municipal storm sewer shall be limited to the following uses in Residential zoning districts: a parking lot; a single-unit residence; a two-unit residence; or a multiunit residence. Provided, however, that the applicant shall be required to submit calculations, which shall be subject to review and approval by the city engineering division, that verify that the total impervious surface area on the particular property or development site that will exist immediately following completion of the proposed new development shall be no greater than the total impervious surface area on the particular property or development site that existed immediately prior to the proposed new development. 2. Soil erosion control. At the time of new site development, including parking lot construction, soil erosion control measures must be installed on the site in conformance with city engineering standards. Said soil erosion measures must be maintained until the site is stabilized to the satisfaction of the city engineering division. d. Open space/landscaping require1. 1.
