17.27.010 Purpose.

The purpose of this chapter is to provide adequate, not excessive parking for all land uses and structures. Benefits to providing the appropriate amount of parking are to reduce impervious surfaces such as parking areas which contribute to the amount of stormwater runoff that flows into area streams, and to utilize land in an efficient manner. (Ord. 2009-702 § 2 (Exh. C); Ord. 2005-609 § 2)

F. Uses Not Specified. Any use not listed above shall meet the requirements of the most similar use as determined by the director.

G. Mixed-Use Parking Requirements. For developments on lots or in buildings with combined uses, the required number of parking spaces shall be the sum of the spaces required for each use and shall not be reduced by more than 10 percent for each use. Examples of combined uses are: a furniture store with a retail display area and an attached storage warehouse, a storage warehouse with attached office, or a church with a parochial school. However, if the hours of use do not overlap, the requirements for the development shall be those of the use or combination of uses which overlap, requiring the greater amount of parking. Examples of mixed uses with hours of use that do not overlap are: an office building with an attached movie theater, a commercial use on the first floor with residential on the upper floors.

H. Shared Parking Facilities. In cases where there are uses in close proximity of each other that operate or are used at entirely different times of the day or week, the director may approve shared parking facilities to satisfy the parking requirements of such uses if the parking facilities are within 300 feet of all uses being served and if the owners of the uses involved present a written agreement clearly setting forth the respective rights under this title, together with proof that the operating times are not in conflict. Examples of potential shared parking uses are stated above in mixed-use parking requirements. The director shall issue a written shared parking approval in accordance with MCMC 14.09.010 if he determines the requirements have been satisfactorily demonstrated.

The director shall periodically confirm the involved uses and may terminate the shared use approval if the required conditions are no longer followed or applicable.

I. Calculations.

1. Area – Square Feet. Unless otherwise specified, square feet refers to the gross building square footage, including outdoor areas used for the same or accessory use, e.g., outdoor eating area of a restaurant.

2. Fractions. When the total number of all required spaces results in a fractional number of parking spaces, one space shall be provided for a fraction of one-half or more, and no space shall be required for a fraction less than one-half.

3. Handicapped Spaces. All retail commercial, offices, personal services, health care, community facilities, multi-family buildings with dwelling units for rent, and other places of public accommodation shall provide handicapped spaces as required by the International Building Code.

J. Credit for On-Street Parking. Based upon a parking study demonstrating adequate on-street parking availability, the director may grant a maximum 30 percent credit for required off-street parking for on-street parking adjacent to a specific use. (Ord. 2009-702 § 2 (Exh. C); Ord. 2005-609 § 2)

17.27.030 Bicycle standards and requirements.

Bicycle parking shall be encouraged in all developments. Where provided, bicycle parking shall be a bike rack or locker-type parking facilities unless otherwise specified.

A. The planning director may require bicycle facilities when it is determined that the use or its location will generate a high volume of bicycle activity. Such a determination will include but not be limited to the following uses:

1. Park/playfield;

2. Public facilities;

3. Library/museum/arboretum;

4. Elementary/secondary school;

5. Sports club; or

6. Retail business (especially when located along a developed or projected bicycle trail or designated bicycle route).

B. Bicycle facilities for patrons, when required, shall be located within 100 feet of the building entrance and shall be designed to allow either a bicycle frame or wheels to be locked to a structure attached to the pavement.

C. All bicycle parking and storage shall be located in safe, visible areas that do not impede pedestrian or vehicle traffic flow, and shall be well lit for nighttime use. (Ord. 2009-702 § 2 (Exh. C); Ord. 2005-609 § 2)

17.27.040 Parking design and construction requirements.

A. Location. Parking spaces required for residential uses shall be provided on the same lot as the principal building. Driveways shall extend a minimum of 20 feet from the edge of improvements in the right-of-way or easement. Off-site parking for nonresidential uses shall be within 100 feet of the principal building or use being served. Minimum distance requirements may be increased up to 300 feet upon a showing of development difficulty or commitment to a shared parking use satisfactory to the director.

B. Handicapped Spaces. All handicapped parking spaces shall be provided and designed in accordance with the 2003 American National Standard, as now or hereafter amended.

C. Dimensional Requirements. All parking spaces shall comply with the dimensional standards of Tables 17-1 through 17-4. Up to 25 percent of all required spaces may be designated and clearly marked for compact cars.

D. Access. All commercial and institutional parking facilities shall have direct access to a street without backing onto the right-of-way.

E. Control Devices. All parking spaces shall be clearly designated with paint, raised rails or other devices. A wheel stop shall be provided for each space which abuts a pedestrian walkway less than 10 feet wide or any structure. All structures shall be guarded with suitable control devices visible to the driver.

F. Surfacing. All parking facilities shall be constructed with a surface appropriate for the use and amount of associated traffic, as approved by the city. Paved surfaces are preferred, and the use of permeable surfacing materials is required when site and soil conditions make it feasible. In addition, the use of LID best management practices such as integrating LID stormwater management facilities into the required landscaping in parking lots is required whenever feasible.

G. Grades. The maximum slope of a parking facility shall be six percent. The minimum slope shall be one and one-half percent.

H. Landscaping. All parking facilities shall be landscaped by a fence, wall, hedge or other suitable vegetation where bordering a public right-of-way or residential zone district. Additional landscaping may be required. Landscaping shall comply with the design review objectives contained in MCMC 17.34.040(C).

I. Maintenance. All parking facilities shall be maintained in a clean and litter-free condition. Landscaped areas shall be free of weeds and dead plant material. Plantings shall be pruned if appropriate.

J. Commercial Vehicles. No commercial vehicle or combination of vehicle and trailer over 6,000 pounds total gross weight shall be parked on any lot in a residential zone.

K. Tandem parking spaces where provided shall not be counted toward the minimum requirements.
