(a) 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 properties or uses may be permitted subject to the following:
1. Shared parking plans may include any lot or structure meeting the parking location requirements. Surrounding 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).
2. A request for a shared parking reduction shall be based on a shared parking analysis, including, but not limited to, the following factors:
a. The number of originally required spaces for different uses or facilities sharing the same parking areas as noted in Table 153.173C; and
b. Documented percentages of required parking needed for different uses at different days and times.
3. 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.
4. Demonstration of parking need. In addition to or in lieu of parking adjustments, 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;
b. The availability of other publicly available parking in the area;
c. The timing of parking use relative to other uses in the area;
d. The parking requirement for similar uses as may be determined by the Director;
e. Whether the all provided parking meets the location requirements;
f. Whether compliance with Table 153.173C is made to the maximum extent practicable;
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.

There shall be a minimum of four feet of clear walkway area and at least two and one-half feet between a curb or wheel stop and any property line, planting area, street, or building.
2. Planted areas shall be installed at a lower grade than the parking lot pavement, include curbing at the edge of a landscaped area and have openings or gaps allowing drainage from the pavement to enter and percolate through the landscaped areas when used for stormwater management purposes, or if required by the City Engineer.
3. Wheel stops may be used in conjunction with accessible parking spaces where an adjacent walkway is installed at the same grade as the parking space. Wheel stops may be used in addition to raised curbs where necessary to prevent vehicle overhang onto adjacent walkways, or near buildings or resources, or in conjunction with curb breaks used for stormwater drainage. Curbs shall be required in all other circumstances.
(e) Striping. Parking areas shall be striped and maintained in good condition to be clearly visible with lines to indicate parking space limits. All striping shall comply with the Ohio Manual of Uniform Traffic Control Devices unless an alternative is approved by the City Engineer.
(f) Parking pedestrian circulation. For each surface parking area that contains over 100 vehicle parking spaces or contains any parking spaces located more than 350 feet from the main entrance of the principal structure, a pedestrian circulation plan shall be submitted and comply with the walkability and pedestrian circulation standards applicable to parking areas in the design guidelines.
(13) Required loading spaces.
(a) Location.
1. Off-street loading spaces may only be located on areas of a lot that are not required to be occupied by a principal or accessory structure.
2. Off-street loading areas may not be located on any parking spaces or parking aisles designated to meet the minimum parking requirements of this section, unless approved in a required parking plan demonstrating that the location and timing of loading activities will not conflict with typical parking use on the site or with vehicular or pedestrian circulation.
3. An alley or service street may be used instead of a separate off-street loading space, subject to approval as part of a required parking plan demonstrating that the loading and delivery activities will be coordinated with other users of the alley to minimize access and circulation conflicts.
4. On-street parking spaces may be counted toward meeting the minimum loading space requirement for a parcel provided that the spaces meet the requirements for parking location, and subject to approval as part of a required parking plan demonstrating that the on-street spaces are of adequate size, number and availability to serve the intended delivery vehicle(s) without creating conflicts with surrounding vehicular, bicycle or pedestrian traffic and circulation.
5. Required fire access zones may not be used to meet loading space requirements.
6. No loading dock, or any loading area used for the storage or staging of materials being transported to or from the site associated with commercial uses, shall be located closer than 50 feet to any lot in a residential district unless entirely contained within a completely enclosed building, or screened as required by § 153.173(H), nor shall any loading dock or loading area directly face a residential district.
(b) Number required.
1. The minimum number of off-street loading spaces required is listed in Table 153.173F.
2. A loading space plan demonstrating the frequency and type of loading activities will be required to be approved by the Architectural Review Board as part of a Minor Project or Final Development Plan.
3. The required number of loading spaces may be increased or reduced by the required reviewing body when it is demonstrated that the frequency and type of loading activities at that location warrant a different number.
4. For principal structures of 25,000 square feet or less in gross floor area, loading and delivery activities may be conducted using an alley or service street, on-street parking spaces, or other on-site parking area, unless the required reviewing body determines that a dedicated off-street loading space is necessary based on the frequency and type of loading activities anticipated for the use.
(c) Loading space dimensions and screening.
1. All off-street loading spaces shall be at least 12-feet wide and 30-feet long with a height clearance of 14 feet, unless the required reviewing body determines that the typical delivery vehicle(s) designated in an approved parking plan can be adequately accommodated by reduced loading space dimensions.
2. Refer to § 153.173(I) for off-street loading area screening requirements.
3. Truck loading and unloading docks and maneuvering areas shall be designed so that truck movements do not interfere with traffic on public streets or off-street parking when vehicles are parked for loading and unloading. Loading areas requiring vehicles to back in from the street are prohibited on West Bridge Street and High Street, unless otherwise permitted by the City Engineer. Vehicles loading or unloading may not extend over any sidewalk or into any public right-of-way between the hours of 6:00 a.m. and midnight, unless located entirely within a designated on-street parking lane or within the vehicular travel lane of an alley or service street as permitted in an approved parking plan.
