• A. Additional Requirements.

  1. More Than One Use on a Site. If more than one use is located on a site, the number of parking spaces provided shall be equal to the sum of the requirements prescribed in this section for each use. Exceptions are strict day use parking (e.g., retail shopping) and evening use parking (e.g., entertainment).

  2. Off-Street Parking Facilities to Serve One Use. Off-street parking facilities for one use shall not be considered as providing required off-street parking facilities for any other use. Exceptions are as provided under subsection F.1 of this section.

  3. Reduction of Off-Street Parking Facilities. No off-street parking facility shall be reduced in capacity or in area without sufficient additional capacity or additional area being provided to comply with the regulations of this title.

  4. Required parking spaces shall be on the same lot as the main building or structure or

• D. Exceptions. The number of required parking spaces may be reduced by up to a total of 50% in the following circumstances:

  1. Parking Generation Study. If applicant provides verifiable data demonstrating that the

City of Rio Vista, CA § 17.48.010

RIO VISTA CODE

§ 17.48.010

actual parking demand for the proposed use will be less than that required by this chapter, the planning commission may reduce the off-street parking obligation by up to 50%.

2. Reduction Based on Parking Survey. An applicant may provide a parking survey to demonstrate that adequate on-street and/or public parking lot spaces exist to serve the use consistent with the use's Peak Parking Demand as defined in Section 17.48.010.J.5. In this circumstance the planning commission may reduce the otherwise applicable off-street parking obligation of a project by up to 50%. If the proposed site has not potential to accommodate off-street parking and the study determines adjacent parking can adequately serve the project without impacting neighboring properties, then all off-street parking requirements may be waived.

3. Use of Existing Building. For a proposed use within an existing building or a building expansion of less than 500 square feet, no additional off-street parking will be required.

4. Off-Site Parking. Up to 50% of the required parking may be developed off-site if such spaces are not more than 400 feet from the use served.

5. Elimination of Existing Off-Street Parking. Elimination of existing off-street parking spaces shall require a planning commission determination, based on evidence provided by the applicant, that remaining off-street parking spaces, if any, and existing on-street and/or public parking lot spaces within 400 feet of the project will be sufficient to meet anticipated parking needs of the project and the immediately surrounding uses.

6. The applicant will be responsible for the collection and submittal of survey or other data sufficient for the planning commission to support the proposed reduction of offstreet parking obligation or elimination of existing off-street parking spaces.

• E. Shared Parking. Public or private parking spaces may be shared by more than one use when operations are not normally conducted during the same hours, or when hours of peak use vary. Requests for the use of shared parking are subject to the approval of the planning commission and must meet the following conditions:

  1. The applicant must satisfactorily demonstrate that substantial conflict shall not exist in the principal hours or periods of peak demand for the uses for which shared spaces are proposed.

  2. Parking spaces designated for shared use shall not be located further than 400 feet from the use served.

3. The parties to a shared parking agreement must provide a copy of their written agreement that is executed by all parties concerned assuring the continued availability of the number of stalls designated for shared use.

   4. The number of existing parking stalls which may be credited against the requirements for proposed structures or uses shall not exceed the number of stalls reasonably anticipated to be available during differing hours of peak demand.

   5. In determining the availability of parking spaces for shared use, peak and off-peak demand shall be calculated using the following general standards, except where data

• E. Existing Uses. No existing use of land or structure shall be deemed to be nonconforming solely because of the lack of off-street loading facilities prescribed in this section, provided

that facilities being used for off-street loading on the effective date of adoption shall not be reduced in capacity to less than the number of berths prescribed in this section or reduced in area to less than the minimum standards prescribed in this section.

• F. Requirements for off-street loading facilities may be waived by the planning commission for new uses proposed entirely within an existing building or where the expansion of an existing building is less than 500 square feet. Such a waiver must be supported by a planning commission determination of the following:

  1. That no feasible location for the off-street loading facility exists on the project site; and

2. That, based on the proposed use and its location, any reductions or waivers of offstreet parking requirements will not result in a traffic or public safety hazard.
