A report form will be provided to the property owner by the city.

J. Recording. Prior to the issuance of a building permit or of any approvals made pursuant to Chapter 20.30 BCC, the owner of property subject to this section shall record an agreement between the city and the property owner with King County division of records and elections and with the Bellevue city clerk that requires compliance with this section by the present and future owners of the property. (Ord. 4822 § 1, 1995.)

14.60.080 Transportation management program – Downtown.

A. The director may require a transportation management program (TMP) for any project proposed within the downtown in order to reduce congestion, reduce peak hour trips, or implement the policies of the comprehensive plan.

B. Programmatic Requirements.

1. The owner of a building with 50,000 gross square feet or more of office shall, in addition to the programmatic elements identified in the Transportation Management Requirement Chart in BCC 14.60.070(F), perform or cause to be performed the following elements:

a. Commuting options information boards for each tenant with 50 or more employees.

b. Leases in which the tenants are required to participate in periodic employee surveys.

c. Identification of parking cost as a separate line item in such leases and a minimum rate for monthly long-term parking, not less than the cost of a current Metro two-zone pass.

2. Duration. The programmatic requirements shall continue for the life of the building.

C. Performance Goals.

1. The owner of a building with 50,000 gross square feet or more of office shall, as part of the TMP for the building, comply with the following performance goals:

a. For every other year beginning with the building’s first certificate of occupancy (CO) anniversary and for 10 years thereafter, the performance goals shall become more restrictive, so that by the tenth year the maximum SOV rate will be reduced by 35 percent from the CO year baseline.

b. The city may adjust the above rates every other year based on review of current conditions in the downtown, the characteristics of the building, and other local or state regulations.

c. These performance goals apply to present and future property owners for the life of the building.

D. Survey and Analysis Requirements.

1. Employee Survey. The property owner shall conduct a survey to determine the employee mode split. The survey must be conducted by an independent agent approved by the city. This survey shall be conducted in a manner to produce a 70 percent response rate and shall be representative of the employee population. If the response rate is less than 70 percent, all nonresponses up to 70 percent shall be considered SOV trips. The survey results shall be used as the basis for calculating performance levels. The city shall provide a survey form to the property owner.

2. Schedule of Survey. The survey is to be conducted every two years; the first survey shall be conducted one year after the issuance of the CO.

3. Analysis of Performance Goals.

a. Single-Occupancy Vehicle Use Formula:

(NS/NT)(100) =

percent SOV use, where:

NS =     

number of employees who commute to work by SOV

NT =

total number of employees.

1. Content of Evaluation Report. The property owner shall submit a report to the city which includes the following elements:

a. The property owner’s compliance with the performance goals listed in BCC 14.60.080(C), including the number of HOV spaces, their location, how HOV spaces are monitored, loading and van parking locations, transportation coordinator activities, the number and location of commuter information centers and employer commuter options boards, an example of lease language, past and current parking costs and ridematch activities.

b. The results of the employee survey, including the survey procedures and the percent SOV use by employees.

c. Any nonrequired activities undertaken by the property owner to encourage HOV and transit use or any unusual circumstances which have affected SOV use.

The city will provide a report form to the property owner.

2. Reporting Schedule. An initial action plan for implementing the TMP shall be submitted within six months of the issuance of the temporary certificate of occupancy. The action plan shall describe transportation management techniques that the property owner will use to encourage HOV use by employees and reduce peak period vehicle trips as necessary to meet the performance goals. City staff will be available to assist in the development of the action plan. The evaluation reports shall occur by building’s first CO anniversary, and every two years thereafter.

F. Failure to Meet Performance Goals.

1. Remedies. If the city determines that the property owner has failed to meet the performance goals of BCC 14.60.080(C), the property owner shall comply with the action plan, employee survey and reporting requirements as set forth below.

2. Action Plan Requirement.

a. Plan Required. If the property owner fails to meet the performance goals, the property owner shall prepare, submit to the city and implement an action plan to meet the performance goals within one year.

b. Adequacy of Plan. The property owner will be allowed flexibility in developing the action plan subject to city review and approval, which approval shall not be unreasonably withheld. As a guide to this review, the city will evaluate the following:

i. The relationship of the number of employees that would be affected by the plan actions to the size of the deficiency which must be reduced.

ii. The effectiveness of proposed actions as they have been applied elsewhere in comparable settings.

iii. The schedule for implementation of the action plan and the assignment of responsibilities for each task.

3. Annual Employee Survey Requirements. An employee survey shall be conducted within one year of the date of submission of the previous report to the city. This survey shall be conducted under the same conditions and using the same methods as described in BCC 14.60.080(D)(1).

4. Annual Report Requirement. A report shall be submitted one year after the submission of the previous report. The report shall include all of the contents described in BCC 14.60.080(E)(1), and in addition shall include descriptions of:

b. Summary of effectiveness of elements of the action plan.

5. Duration. The property owner shall comply with the action plan, the annual survey and the annual report requirements every year that the property owner fails to meet the performance goals up to a maximum of six years after submission of the first report.

6. Assurance Device. In the event of a failure by the property owner to meet the performance goals, the property owner shall provide to the city an assurance bond, or other assurance device referenced in BCC 14.60.021(C), at the property owner’s option, securing any financial incentives prescribed in an action plan. The assurance device shall equal the cost of the maximum incentive levels which could be required for the following year as referenced in the action plan. The amount of the assurance device shall be determined when the level of activity is determined on the action plan. The assurance device shall be issued not later than 60 days after this determination.

B. Complete street frontage improvements shall be installed along the entire street frontage of the property at the sole cost of the permittee as directed by the review engineer. Street frontage improvements may include curb, gutter, sidewalk, storm drainage, street lighting, traffic signal equipment, utility installation or relocation, landscaping strip, street trees and landscaping, irrigation, street widening, and channelization. Beyond the property frontage, the permittee shall provide ramps from the new sidewalk or walkway to the existing shoulder, and pavement and channelization tapering back to the existing pavement and channelization as needed for safety.

C. When (due to site topography, city plans for improvement projects, or other similar reasons) the review engineer determines that street frontage improvements cannot or should not be constructed at the time of building construction, the property owner shall, prior to issuance of the building permit, at the direction of the review engineer:

1. Pay to the city an amount equal to the property owner’s cost of installing the required improvements prior to issuance of a building permit. The property owner shall provide documentation satisfactory to the city of materials costs, quantities, and labor costs; or

2. Record an agreement which provides for these improvements to be installed by the property owner by a date acceptable to the city; or

3. Record an agreement to not protest a local improvement district to improve the street frontage.

D. If, at a time subsequent to the issuance of a building permit, a local improvement district is established which includes the property for which the building permit was issued, and if such condition or agreement as prescribed in this section has been performed by the developer, the condition or agreement may be considered in the compilation of the local improvement district assessment roll as a pre‑existing contract with the city, for which the property owner may be credited against the assessment with the appropriate amount of costs of construction expended by the developer.

E. The requirement for installation of frontage improvements may be waived by the review engineer under either of the following conditions:

1. Adjacent street frontage improvements are unlikely to be installed in the foreseeable future; or

2. The installation of the required improvement would cause significant adverse environmental impacts. (Ord. 4822 § 1, 1995.)

14.60.240 Street intersection sight obstruction.

A. Notwithstanding any other provision of this code, no vehicles shall be parked or any sign, fence, hedge, shrubbery, natural growth or other obstruction installed, set out or maintained which obstructs the view of motor vehicle operators at an intersection within the sight areas defined in BCC 14.60.240(B) and between the height limits defined in BCC 14.60.240(C). BCC 14.60.240(D) specifies what constitutes an obstruction to the view of motor vehicle operators. For the purpose of this code, “intersection” shall include: the intersection of two public streets; the intersection of a commercial driveway with a public street; the intersection of a residential driveway with a public street; and the intersection of a private street with a public street.

B. The sight area at an intersection is defined as the area bounded by setback lines, or bounded by setback lines and the edge of the traveled lane. Setbacks for intersection types are as specified in the following paragraphs.

1. Major Street/Minor Street. Intersections of this type have no control or flashing yellow on the major street, and a stop sign or flashing red signal on the minor street. Private commercial driveways (which may or may not have a stop sign) used by the public for entering any city street are also included in intersections of this type.

The setback line shall be defined as a line which joins a point in the center of the minor street approach lane located 14 feet back from the edge of the through‑street approach lane (Point A) and a point in the center of the through‑street approach lane (Point B). The location of Point B in the through-street approach lane is specified in the following table:

Posted Speed Limit For Major Street

Distance from Center of Intersection to Point B (Left Approach Only)

40 MPH

410 Feet

35 MPH

360 Feet

30 MPH

300 Feet

25 MPH

250 Feet

Where the major street is a divided highway, only the left setback line applies. Where the major street is a one‑way street, only the setback line toward the direction of approach applies.

Modification. Where major obstacles such as pre‑existing permanent structures, elevated contour of the ground, embankments, or other elements preclude the reasonable enforcement of the setback lines specified above, these setbacks may be modified at the discretion of the city traffic engineer. The minor street setback distance to Point A may be reduced from 14 feet to 10 feet, and the major street Point B location may be modified as follows:

Posted Speed Limit For Major Street

Distance from Center of

Intersection to Point B

40 MPH

325 Feet

35 MPH

250 Feet

30 MPH

200 Feet

25 MPH

150 Feet

2. Uncontrolled Intersection. For intersections with no traffic control on any approach, the setback lines join a point on the approach located 50 feet back from the center of the intersection with points located 80 feet back from the center of the intersection on the right and left hand streets. All points are on the street centerlines.

3. Yield Intersection and T Intersection. Yield intersections have a yield sign on one or both of the minor street approaches, and no control on the major street approaches. The setback lines for yield intersections join a point in the center of the yield approach lane 25 feet back from the edge of the crossing traffic lane with points in the centers of the crossing approach lanes 100 feet back from the center of the intersection. This setback also applies to a T intersection with no restrictive control; in this case the 25‑foot setback point is on the stem of the T.

4. Signalized Intersection. For signalized intersection approaches with right-turn-on-red-after-stop permitted, the left setback line joins a point in the center of the minor street approach lane located 14 feet back from the edge of the through‑street approach lane (Point A) and a point in the center of the left through‑street approach lane (Point B). The location of Point A may be reduced to 10 feet subject to approval of the traffic engineer. The location of Point B is specified in the following table:

Posted Speed Limit For Major Street

Distance from Center of Intersection to Point B (Left Approach Only)

40 MPH

325 Feet

35 MPH

250 Feet

30 MPH

200 Feet

25 MPH

150 Feet

5. Residential Driveway Intersection. For the intersection of a residential driveway with a public street, the setback line joins a point in the center of the driveway (Point A) with a point in the center of the through-street approach lane (Point B). The setback distance of Point A from the edge of the traveled lane is 10 feet. The location of Point B is specified in the following table:

Posted Speed Limit For Major Street

Distance from Center of

Intersection to Point B

40 MPH

325 Feet

35 MPH

250 Feet

30 MPH

200 Feet

25 MPH

150 Feet

Modification. When the residential driveway is located on a residential street with a sharp curve adjacent to the driveway, the distance to Point B may be reduced from 150 feet to 100 feet. For residential driveways with major obstacles or special view problems, the setback distance on the driveway (Point A) may be reduced from 10 feet to eight feet, subject to approval by the traffic engineer.

6. Sightline Setback – Other. For intersections not clearly included in the above types and for which view problems may exist, the traffic engineer will establish setback lines as required.

C. Sight Obstruction Height Limits. Sight obstruction, as defined in subsection D of this section, shall not be permitted above a line two and one-half feet above the street surface within the sight areas established in subsection B of this section. However, sight obstructions above a line seven and one‑half feet above the street surface are permitted. For residential driveways, this upper height requirement is reduced from seven and one-half feet to six feet.

D. Sight Obstruction Defined.

1. For minor street/through street intersections, as defined in subsections (B)(1), (B)(4) and (B)(5) of this section, the following obstructions within the established sight areas shall be permitted:

a. One obstruction within each sight area which presents a maximum of two and one‑half feet width when viewed from the applicable angle, which has at least two feet clear view inside the obstruction (on the side away from the intersection). At distances greater than 40 feet from the view point, the obstruction may present a maximum of four feet width.

b. Any number of obstructions one and one‑half feet or less in maximum width when viewed from any applicable angle; provided there is equal open space on each side of the obstruction for all angles.

2. For intersections with no signalization or stop signs, as defined in subsections (B)(2) and (B)(3) of this section, the following obstructions within the established sight areas shall be permitted:

a. One obstruction within each sight area which presents a maximum of eight feet width when viewed from any applicable angle, and which has at least four feet clear view inside the obstruction and eight feet clear view between the obstruction and the edge of the traffic lanes; or

b. Two obstructions within each sight area each of which presents a maximum of five feet width when viewed from any applicable angle, and separated by four feet on more open space when viewed from all applicable angles, and which have at least four feet clear view inside the obstructions and eight feet clear view between the obstructions and the edge of the traffic lanes; or

c. Any number of obstructions one foot or less in width; provided they obstruct no more than two feet continuous obstruction width when viewed from any applicable angle; and provided there is equal open space on each side of the obstruction for all angles.

E. Where unusual conditions preclude the application of the foregoing provisions of this section in a reasonable manner, or where a special viewing problem exists, the traffic engineer will determine when an intersection view obstruction exists, based on the intent of this section.

F. Every obstruction of the sort prohibited in this section hereafter installed or permitted to remain shall be deemed a violation of this code. (Ord. 4822 § 1, 1995.)

14.60.241 Sight distance requirements for pedestrian safety.

A. The minimum sight distance for pedestrian safety shall be determined as follows: the driver of an exiting vehicle shall be able to view a one-foot-high object 15 feet away from either edge of the driveway throat when the driver’s eye is 14 feet behind the back of the sidewalk.

B. The minimum sight distance defined in subsection A of this section shall be maintained at all driveways, buildings, and garage entrances where structures, wing walls, etc. are located adjacent to or in close proximity to a pedestrian walkway.

C. Sight lines to traffic control devices such as signs, signals, etc. shall not be obscured by landscaping, street furniture, marquees, awnings, or other such obstructions. (Ord. 4822 § 1, 1995.)

14.60.250 Pavement restoration for trenching in right-of-way.

A. To ensure that public street pavement is not degraded by trenching, excavation, and pavement restoration activities, the trench backfill and restoration section of the transportation technical manual shall be adhered to when trenching within the paved portion of the city right-of-way.

B. Modifications or exceptions to subsection A of this section may be approved by the director upon written request by the permittee and demonstration of a satisfactory alternative.

C. A five-year moratorium on pavement trenching is effective upon completion of new street construction and upon pavement overlay of an existing street.

D. Modifications or exceptions to subsection C of this section may be approved by the director under compelling circumstances and emergencies, such as utility failures, main breaks, etc. (Ord. 4822 § 1, 1995.)
