18.50.180 Electric vehicle parking space design standards.
(1) An electric vehicle parking space may be included in the calculation for minimum required parking spaces as required in CMC 18.31.450 and 18.50.030.
(2) The Director may reduce or waive the requirement for electric vehicle parking spaces in any zone if the applicant can demonstrate:
(a) That a shared parking facility provides access to an adjacent parking facility with a minimum of two existing electric vehicle parking spaces; or
(b) That the proposed parking facility is providing cross-access to an adjacent parking facility with a minimum of two existing electric vehicle parking spaces; and
(c) The applicant has a contract for the shared use of the above-required electric vehicle parking spaces between the appropriate property owners. The contract shall be recorded with King County Records and Elections as a deed restriction that cannot be modified or revoked without approval by the Director.
(3) Where electric vehicle parking spaces are required in parking lots or parking garages, accessible vehicle parking spaces shall be provided.
(a) Accessible electric vehicle parking spaces should be located in close proximity to the building or facility entrance and shall connect to a barrier-free accessible route of travel. It is not required to designate the parking space exclusively for the use of disabled persons.
(4) The provision of electric vehicle parking spaces will vary based on the design and use of the primary parking lot. The following required and additional location and design criteria are provided in recognition of the various parking lot layout options. Where provided, electric vehicle charging spaces shall include the following:
(a) Each space shall be posted with signage indicating the space is only for electric vehicle charging purposes, except for spaces in single-family, cottage, townhouse, and duplex development. Days and hours of operation shall be included if time limits or tow away provisions are to be enforced. Refer to the 2009 Manual on Uniform Traffic Control Devices (MUTCD) for electric vehicle and parking signs, specifically D9-11b, D9-11bP, R7-2, and R7-108, and as amended.
(b) Electric vehicle supply equipment (EVSE) shall be maintained, including the functioning of the charging equipment. A phone number or other contact information shall be provided on the EVSE for reporting when the equipment is not functioning or when other problems are encountered.
(c) Where EVSE is provided within an adjacent pedestrian circulation area, such as a sidewalk or accessible route to the building entrance, the EVSE shall be located so as not to interfere with ADA accessibility requirements.
(d) Where EVSE is installed, adequate site lighting shall exist, unless charging is for daytime purposes only.
(e) EVSE outlets and connector devices shall be no less than 36 inches and no higher than 48 inches from the surface where mounted, and shall contain a retraction device or a place to hang permanent cords and connectors sufficiently above the ground or paved surface.
(f) Except for parallel parking stalls, adequate equipment protection, such as wheel stops or concrete-filled steel bollards, shall be used. Curbing may be used in lieu of wheel stops or bollards if equipment is set back a minimum of 24 inches from the face of the curb.
(5) Parking for electric vehicles should also consider the following:
(a) Information on the EVSE identifying voltage and amperage levels and any time of use, fees, or safety information.
(b) Installation of directional signs at the parking lot entrance and at appropriate decision points to guide motorists to the electric vehicle parking space(s). Refer to the 2009 Manual on Uniform Traffic Control Devices (MUTCD) for electric vehicle and directional signs, specifically D9-11b, D9-11bP and M6-1, and as amended.
(6) To allow for maintenance and notification, the owner of any private new EVSE that will be publicly available shall be required to provide information on the parking space’s geographic location, date of installation, equipment type and model, and owner contact information.
(7) On-street electric vehicle parking spaces shall conform to the following:
(a) On-street electric vehicle parking spaces are not permitted in the R-1 through R-18 zones.
(b) On-street electric vehicle parking spaces in the TC, MC, GC and MHO zone shall be installed at either end of designated on-street parking.
(c) Subsequent on-street electric vehicle parking spaces should be installed adjacent to existing stations.
(d) EVSE shall be installed in a well-lit area, on a hard surface, near the front of the designated parking space and should provide a minimum of 24 inches clearance from the face of the curb and not impede the required minimum ADA accessible route on the sidewalk.
