(1) Definitions. The definitions in this section apply throughout these rules.

(a) Statutory definitions. The terms listed in this subsection are defined in the CTR statutes (RCW 70.94.521 through 70.94.555).

(i) "A major employer" means a private or public employer, including state agencies, that employs one hundred or more full-time employees at a single worksite who begin their regular work day between 6:00 a.m. and 9:00 a.m. on weekdays for at least twelve continuous months during the year.

(iii) "Person hours of delay" means the daily person hours of delay per mile in the peak period of 6:00 a.m. to 9:00 a.m., as calculated using the best available methodology by the department of transportation.

(iv) "Commute trip" means trips made from a worker's home to a worksite during the peak period of 6:00 a.m. to 9:00 a.m. on weekdays.

(v) "Proportion of single-occupant vehicle commute trips" means the number of commute trips made by single-occupant automobiles divided by the number of full-time employees.

(vi) "Commute trip vehicle miles traveled per employee" means the sum of the individual vehicle commute trip lengths in miles over a set period divided by the number of full-time employees during that period.

(vii) "Growth and transportation efficiency center" means a defined, compact, mixed-use urban area that contains jobs or housing and supports multiple modes of transportation. For the purpose of funding, a growth and transportation efficiency center must meet minimum criteria established by the commute trip reduction board under RCW 70.94.537, and must be certified by a regional transportation planning organization as established in RCW 47.80.020.

(viii) "Affected urban growth area" means:

(A) An urban growth area, designated pursuant to RCW 36.70A.110, whose boundaries contain a state highway segment exceeding the one hundred person hours of delay threshold calculated by the department of transportation, and any contiguous urban growth areas; and

(B) An urban growth area, designated pursuant to RCW 36.70A.110, containing a jurisdiction with a population over seventy thousand that adopted a commute trip reduction ordinance before the year 2000, and any contiguous urban growth areas.

(ix) "Certification" means a determination by a regional transportation planning organization that a locally designated growth and transportation efficiency center program meets the minimum criteria developed in a collaborative regional process and the rules established by the department of transportation.

(b) Terms defined by rule. The terms listed in this subsection are defined herein and apply throughout these rules.

(i) "Goal" means a purpose toward which efforts are directed.

(ii) "Target" means a quantifiable or measurable value that is expressed as a desired level of performance, against which actual achievement can be compared in order to assess progress.

(iii) "Drive-alone" means single-occupant vehicle.

(iv) "Single-occupant vehicle" means a motor vehicle, including a motorcycle, occupied by one person for commute purposes. If there are other passengers occupying the motor vehicle, but the ages of these passengers are sixteen or under, the motor vehicle is still considered a "single-occupant vehicle" for measurement purposes.

(v) "Nondrive-alone travel" means travel by a method other than single-occupant vehicle. Travel avoided by telework, alternative work schedules, or condensed work weeks shall also be considered as nondrive-alone travel.

(vi) "Base year value" means the measured values per employee at a major employer worksite, on which commute trip reduction targets for the major employer worksite shall be based.

(vii) "Jurisdiction's base year measurement" means the year of the first measurement. For those jurisdictions which have used the CTR survey, the jurisdiction's base year measurement shall be determined based on employee surveys administered in the 2007-2008 survey cycle. If complete employee survey data from the 2007-2008 survey cycle is not available, then the base year measurement shall be calculated from the earliest available set of complete employee survey data. For jurisdictions which do not use the CTR survey for measurement, this shall be determined using equivalent 2007-2008 data.

(viii) "Affected employee" means a full-time employee who begins his or her regular workday at a major employer worksite between 6:00 and 9:00 a.m. (inclusive) on two or more weekdays for at least twelve continuous months, who is not an independent contractor, and who is scheduled to be employed on a continuous basis for fifty-two weeks for an average of at least thirty-five hours per week.

(ix) "CTR commuter" means a resident or employee in an affected urban growth area who is a participant in the city or county's commute trip reduction program, including any growth and transportation and efficiency center ("GTEC") programs, implemented to meet the city or county's established targets.

(x) "Commute trip vehicle miles traveled per CTR commuter" means the sum of the individual vehicle commute trip lengths in miles over a set period divided by the number of CTR commuters during that period.

(xi) "Major employer worksite" means the physical location occupied by a major employer, as determined by a local jurisdiction.

(xii) "Voluntary employer worksite" means the physical location occupied by an employer who is voluntarily implementing a CTR program.

(2) Identification of CTR jurisdictions. This section establishes the process to be used by WSDOT to determine the state's affected urban growth areas and lists the state's affected urban growth areas.

(a) Process to determine affected urban growth areas. WSDOT shall use the definition of an affected urban growth area in RCW 70.94.524 to determine the list of affected urban growth areas. WSDOT shall use the most recent set of valid and available data that covers the entire state highway system to calculate the one hundred person hours of delay threshold for state highway segments. WSDOT shall use the most recent geographical information for the state's urban growth areas as provided by the department of community, trade and economic development, or its successor.

(b) Listing of affected urban growth areas. The cities and counties within or containing an affected urban growth area, as determined by WSDOT, are:

(i) Clark County and the cities of Camas, Vancouver, and Washougal;

(ii) King County and the cities of Algona, Auburn, Beaux Arts, Bellevue, Black Diamond, Bothell, Burien, Clyde Hill, Covington, Des Moines, Federal Way, Hunts Point, Issaquah, Kenmore, Kent, Kirkland, Lake Forest Park, Maple Valley, Medina, Mercer Island, Newcastle, Normandy Park, Pacific, Redmond, Renton, Sammamish, SeaTac, Seattle, Shoreline, Tukwila, Woodinville, and Yarrow Point;

(iii) Kitsap County and the cities of Bainbridge Island, Bremerton, and Port Orchard;

(iv) Pierce County and the cities of Bonney Lake, DuPont, Edgewood, Fife, Fircrest, Gig Harbor, Lakewood, Milton, Orting, Puyallup, Ruston, Steilacoom, Sumner, Tacoma, and University Place;

(v) Snohomish County and the cities of Arlington, Bothell, Brier, Edmonds, Everett, Lake Stevens, Lynnwood, Marysville, Mill Creek, Monroe, Mountlake Terrace, Mukilteo, Snohomish, and Woodway;

(vii) Thurston County and the cities of Lacey, Olympia, and Tumwater;

(viii) Whatcom County and the cities of Bellingham and Ferndale; and

(ix) Yakima County and the cities of Selah, Union Gap, and Yakima.

(c) Listing of affected urban growth areas exempted from CTR requirements for a period not exceeding two years from March 1, 2007. The cities or counties within an affected urban growth area, as determined by WSDOT, but which the legislature in RCW 70.94.527(12) has exempted from CTR requirements for a period not exceeding two years from March 1, 2007, are:

(i) Benton County and the cities of Kennewick, Richland, and West Richland; and

(ii) Franklin County and the city of Pasco.

(d) Notification of cities, counties, and regional transportation planning organizations (RTPOs) required to adopt CTR plans. WSDOT shall notify the cities, counties, and RTPOs that are determined to be in the affected urban growth areas. Cities and counties in the affected urban growth areas shall identify the major employers, if any, within their boundaries. Only those cities and counties containing a major employer in the affected urban growth area within the boundaries of their official jurisdiction shall be required to adopt a local CTR plan. Only those regional transportation planning organizations whose planning territory encompasses a city or county required to adopt a local CTR plan shall be required to adopt a regional CTR plan.
