Mr. Brian Brand El Baylis Associates 500 - 108th Avenue N.E. Bellevue, WA 98004 SUBJECT: TUKWILA OFFICE BUILDING Dear Mr. Brand: REC el EnvIls associates . APR 1 1819 In response to your request of March 29, 1979, The TRANSPO Group has prepared the following report summarizing an analysis of several spe- cific traffic related issues as they pertain to the subject project. This report is intended to provide information which will assist you and your engineer with the design of the building site by suggesting design elements that will help mitigate any existing or potential future adverse traffic related impacts. Specifically, issues addressed in our analysis include safe stopping sight distance, the design of the driveway to the parking lot, and the safety of turning movements in and out of the driveway to and from Southcenter Boulevard. The process followed to prepare this analysis was to assemble infor- mation on the existing traffic and transportation conditions in the project vicinity, forecast traffic volumes generated by the subject . project, analyze these traffic forecasts to identify any adverse impacts, and recommend any mitigating measures that might eliminate or reduce the severity of the impacts. Proposed Project This project is proposed to be a two -story office building with a third basement level for parking that comprises 35,000 gross square feet and 115 parking spaces. The building site is located immediately east of the Tukwila City Hall on a rectangular parcel which climbs to the north from Southcenter Boulevard. Access to the property is proposed to be off Southcenter Boulevard via a single- access driveway which, to com- pensate for the steep grade, makes a sweeping "S" turn up the front slope of the property. The driveway is 25 feet wide, is designed to carry one lane of traffic in each direction and sometimes reaches a grade of about 15 percent. A sketch of this site, including this access driveway, is shown on Attachment 1. Twenty -three 148th Avenue Southeast • BeHevue, Washington 98007 • (206) 641 -3881 • Mr. Brian Brand Page Two Existing Conditions Next to the site, Southcenter Boulevard is a 24 foot wide, two -lane major arterial connecting Interurban Avenue to the east with I -5 and South - center Parkway to the west. This road functions as a collector- distributor roadway where north -south streets act as tributaries to the residences up on the hill north of the site. To the west, the nearest intersection is 62nd Avenue S. which serves City Hall and some existing apartments on the top of the hill (and soon will serve about 330 units of condominiums and apartments as well as two office buildings). A private road just east of the subject site intersects Southcenter Boulevard on an angle and will serve the Xerox Headquarters Building and the existing office building slightly further to the east. Further east, 65th Avenue S. is the major arterial serving the residential area on the Hill. Presently Southcenter Boulevard widens at its intersection with 62nd Avenue S. to include a center, left turn, storage lane. The capital improvement program for the City of Tukwila shows Southcenter Boulevard is planned to be reconstructed to a four -lane roadway. There are no current plans to install a traffic signal on Southcenter Boulevard at 62nd Avenue S. or at 65th Avenue S. Both the existing and planned edge of roadway are shown on Attachment 2. A field inspection of the site shows vegetation has overgrown along the north side of the road and blocks a person's line of sight as they look east on Southcenter Boulevard from the location where the proposed driveway to the office building is to be located. It appears the maximum sight distance at this location is about 170 feet. This is compared with the desired safe stopping distance of 250 feet associated with the 35 mile per hour posted speed for Southcenter Boulevard. Traffic control on streets in the area provided by STOP signs which control the side street volumes permitting the higher volume main street traffic to pass without interruption and therefore minimize the total delay experienced at the intersection. Based on traffic counts made by the City of Tukwila, and supplemented by information assembled by The TRANSPO Group, the daily and peak hour volumes on Southcenter Boulevard and other streets in the area are depicted on Attachment 2. These volumes include the traffic anticipated to be generated by the aforementioned developments (i.e., condominiums and office buildings). This shows that Southcenter Boulevard carries about 5,300 vehicles per day with about even volumes passing in each direction. During the evening peak hour, Southcenter Boulevard serves about 260 vehicles per hour (vph) traveling eastbound and 250 vph westbound. fS Mr. Brian Brand Page Three `Ms TPANS This directional split during the evening peak hour is unusually well . balanced considering the typical pattern where one direction of flow is substantially higher than the other - the heavier flow typically pre- dominated by work -to -home trips. Using techniques outlined in a Highway Capacity Manual, this road is shown to operate at a level of service B which is considered very good for urban conditions. When the road is widened to four lanes, it is estimated that the level of service will increase to level of service A which is the best possible level. Forecasted Traffic Volumes Statistics from the Institute of Transportation Engineers', Trip Generation Manual; Arizona Department of Transportations', Trip Generation Intensity Factors Manual, as well as independent accounts made by The TRANSPO Group, show that general multi- tenant office buildings similar to subject project generate about 14 vehicle trips per day per 1,000 gross leaseable square feet and about 2.5 vehicle trips per hour during the evening peak hour for every 1,000 gross leaseable square feet. When these trip generation rates are applied to the gross square footage contained in this office building, it is anticipated it will generate about 480 vehicles per day (240 round trips). During the evening peak hour about 80 trips will be generated with the majority traveling away from the site (70 vph outbound and 10 vph inbound). Normally the influence of the public transportation system is incorporated into these traffic volume estimates through a process known as a mode split. For this analysis, however, this step was not introduced which results in traffic volumes that might be slightly higher than normal. Based on previous studies in the area and existing traffic counts at nearby intersections, it is estimated that the major of the travel to and from this site will be oriented to the west since this provides optimal access to both I -5 and I -405 which provides best direct access to destinations outside the immediate service area. Considering that the average work trip in the region is 9.3 miles, it is safe to assume that a large portion of the trips will be using limited access facilities like I -405, SR 920, and I -5. The resulting daily and evening peak hour volumes are shown on Attachment 3. • Mr. Brian Brand Page Four • T13 spo Traffic Analysis, Conclusions and Recommendations The traffic analysis for this site revolves around the ability to make left turns in and out of the access road. The analysis found there were more than three times as many gaps as are needed by the traffic turning on or off Southcenter Boulevard. The ease of turning onto or off of Southcenter Boulevard will be made even easier when it is widened to four lanes. As noted earlier, there is insufficient sight distance to the east from the point where the proposed driveway intersects with Southcenter Boulevard. Accordingly, the existing landscaping will have to be cut back severely so a minimum of 250 feet safe stopping sight dis- tance is provided. Since the site is being regraded for better align- ment of the access road it seems appropriate that the area south of the road be cut back and low lying landscaping be planted (i.e., ground - cover so this minimum sight distance can be provided). As a added safety measure it might be desirable to redesign the driveway slightly to include a flat platform at the foot of the road so drivers can have a,more clear view of traffic, especially as they look to the west. A STOP sign and STOP bar should be installed at the foot of the access driveway to control traffic entering onto Southcenter Boulevard. The 15 percent grade on the driveway is the maximum permitted by the City and since it runs for a very short distance it does not appear to present a significant safety hazard. To enhance the safety on this access drive, especially at the turns, it is probably best to paint a centerline and reinforce the marking by placing 4 inch diameter traffic buttons to provide a tactile as well as visual reference for drivers. I trust this analysis responds to your needs and the above mentioned recommendations will assist you in the design of the access to the site. If you or the City have any questions after your review of this report, please feel free to call*me. Sincerely, The TRANSPO Group David D.
