This chapter is intended to provide standards on surface paving and design requirements for off-street parking lots and areas, sales lots, loading and unloading areas, personal and recreational vehicle parking, truck terminals, intermodal facilities and storage uses. The lawful use of such existing uses immediately prior to the effective date of the ordinance codified in this chapter may be continued although such designs do not conform to such standards. When any of these items are to be improved, the design shall meet the new requirements within this code.

(Ord. 5532 § 1 (part), 2001)

1. All of the applicable provisions contained within this chapter regarding number of spaces, area or usability of existing parking, loading, and unloading spaces or other areas requiring a paved surface, shall be complied with when any of the following actions occur:
   1. Construction of any new residential and/or non-residential development;
   2. Building additions, expansions, and/or remodels for existing development:
      
      1. Non-residential uses: Any building addition(s), expansion(s), and/or remodel(s) that results an increase in the total number of required off-street parking spaces for a premises by 50% or more; and
         
      2. Residential uses: Any addition or remodel that increases the total number of dwelling units on a premises, or any conversion of an existing dwelling into a group care home, boarding, lodging, or rooming house and/or bed and breakfast use.
         
   3. Building additions and/or detached accessory structures that are designed in a manner where they are capable of being used for parking motorized vehicles, recreational vehicles, and/or boats, or which are intended to be used for loading/unloading, warehousing and distributing stored items, materials, and/or products shall be accessed by a hard-surfaced paved driveway in accordance with the standards stated in this Chapter; and
   4. All off-street parking requirements associated with any special zoning overlay, development plan, or master planned area in the City shall supersede the requirements stated in this Chapter.
2. Contractual agreements may be made between uses which generate parking and at different intervals in such a manner that the requirements of more than one use may be met by the same space, provided the parking demand for each use involved is met. All other required parking spaces shall be located a distance not to exceed four hundred (400) feet from the building or use which they are required to serve, measured in a straight line from the building. Off-site parking owned by or affiliated directly with the owner of the use it serves may be located up to one thousand three hundred twenty (1,320) feet from the use it serves, measured in a straight line from the building.
3. In the event several uses occupy a structure or parcel of land, the total requirements for off-street parking or loading and unloading spaces shall be the sum of the requirements of the several uses computed separately.
4. Parking and loading or unloading spaces shall not be located in a required front yard with the exception of commercial and industrial districts, but may be located within a required side or rear yard.
5. All such off-street parking lots and areas, sales lots, apron space and loading and unloading spaces shall be so drained as to prevent damage to abutting properties and/or public streets;
6. All off-street parking lots and areas, sales lots and loading and unloading spaces, including entrances, exits and driveway approaches shall be constructed of hard surface concrete, concrete pavers, or asphalt, unless otherwise stated in this chapter, to prevent mud, dust, or loose material. Asphalt grindings and seal coats are not acceptable surfaces. Paving standards contained in this section should be considered minimum standards.
7. In non one and two family uses, all parking surfaces, spaces, circulation and aisles along the outer boundaries of a parking lot, vehicle entry paths, apron spaces, all driveways and other traveled areas shall be set back a minimum of five feet from the property line unless required for approved access.
8. Barriers must be located for lots over seven thousand five hundred (7,500) square feet in area to contain the parking within the approved parking lot. For parking lots with less than seven thousand five hundred (7,500) square feet in area the following setbacks shall only apply to the side(s) that directly abut public right-of-way. However, appropriate barriers are needed to protect adjacent buildings and structures on a zero setback side.
   
   

   Barrier	Setback from Property Line	Setback from Parking Surface
   A curb at least six inches in height	5 feet	0
   Bump rail at least four inches in height	5 feet	3 feet
   Guardrail barrier of eighteen to thirty (30) inches in height	5 feet	0
   Post and cable barrier or bollard and chain of eighteen to thirty (30) inches in height	5 feet	0
