City of Federal Way 33325 81h Avenue S Federal WA 98003 RE: Traditions at Federal Way Revised Paving Section for S 3161h Place Dear Mr. Elliott: N G I N E E R S L Lc RESUBMITTED Due to the condition of the existing road surface fronting the main entry for this facility, the proponent is electing to repave the full width of S 316th Place at their expense. The Contractor has proposed a paving section that ultimately results in 4-inches of paving over 4-inches of crushed rock. The intention is that 2.5-inches of paving would go down initially for the duration of the construction with a final 1.5-inch lift to be completed closer to the end of the project. This phased paving provides advantages to both the construction of the project and the City. There was some concern that this paving section did not meet the original geotechnical engineering recommendations, so the geotechnical engineer has prepared the attached letter for your review and approval. Please let us know if this paving section can be approved or if there is more information you require. With the end of the summer coming to a quick close, your prompt attention to this would be very much appreciated. Thank you for your help.

With respect to hot -mix asphalt (HMA) and crushed rock base (CRB) thicknesses, the referenced geotechnical engineering study (study) recommended three inches of HMA placed over six inches of CRB. Instead, we understand you desire to place four inches of HMA atop four inches of CRB. We used the PAVEXpress design tool to determine the total structural number (SN) of each pavement scenario. Design output is attached to this letter for reference. Based on the results of the analyses, the pavement section recommended in the study produces a SN of 2.16, and the desired pavement section produces a higher SN of 2.32. As such, it is our opinion installing four inches of HMA atop four inches of CRB is acceptable for heavily loaded areas from a geotechnical standpoint.

As outlined in the referenced report, the geologic setting of the subject site is Vashon till (underlying fill), as confirmed by our observations of dense to very dense, silty sand with gravel at the boring locations. During our subsurface exploration completed on August 22, 2017, groundwater was encountered between depths of about 21 to 26 feet below the existing ground surface (bgs) at the boring locations. The observed groundwater is representative of discrete seepage zones within the Vashon till rather than a groundwater table. To supplement our field observations, we reviewed historic subsurface data from explorations as near as possible to the site. Based on our review, the seasonal high groundwater table is likely present at great depth beneath the subject site and surrounding area and is estimated at roughly 60 to 100 feet bgs. Given our understanding of the proposed construction, it is our opinion the seasonal high groundwater table will not be encountered during site earthwork and grading activities. To be affected by possible uplift pressures resulting from buoyancy, a foundation must be submerged below the groundwater table. For this project, our field observations indicate that discrete, perched groundwater seeps, rather than the groundwater table, may be � ., ggyptered .atw footing subgrade elevations. Therefore, it is our opinion uplift pressures and buoyancy will not' D impact the proposed stormwater detention system and need not be considered inofflian.110 2019 1805 - 1361h Place N.E., Suite 201 • Bellcvuc, WA 98005 • (425) 449-4704 • FAX (425) teOFEDERAL WAY ITY DEVE Dr MEET Affinity at Federal Way, LLC February 5, 2019 ES-5465.02 Page 2 We trust this letter meets your current needs.

The following presents the variance request including the traffic operations analysis completed for the proposed driveway location and review of access safety through assessment of intersection sight distance. Project Description The project site is located south of S 316th Place and west of Pete Von Reichbauer Way S in the city of Federal Way. The site is currently vacant. Four total driveways are proposed: one driveway via S 316th Place for truck loading operations, two via S 316th Place designated for a fire truck turn around as well as the upper level garage entrance, and the last driveway via Pete Von Reichbauer Way S that accesses the lower level garage entrance. A site plan is provided in Attachment 1. As discussed with City staff, the Pete Von Reichbauer Way S driveway is being requested to provide a second access to the parking garage, accessing the lower level. In order to maximize the parking supply and meet City parking codes, internal garage ramping is not proposed. Instead, the proposed driveway on Pete Von Reichbauer Way S would access the lower level of parking only. Driveways on S 316th Place would access the upper level of the parking garage. Previous requests to locate the additional parking garage driveway on S 316th Place were denied based on conflicts with opposing driveways and intersection spacing. The proposed Pete Von Reichbauer Way driveway would be aligned with an existing Town Square Park driveway on the opposite side of the street and would be restricted to right -turn in and right -turn out operations only. Variance Request FWRC 19.135.280(2) requires 150 feet of separation from driveways and intersections; measured centerline to centerline. The proposed driveway on Pete Von Reichbauer Way S would be located approximately 96 feet south of the S 316th Place intersection as shown in Figure 1. RECEIVED MAR 2 9 2018 CITY OF FEDERAL WAY COMMUNITY DEVELOPMENT 12131 113th Avenue NE, Suite 203, Kirkland, WA 98034 1 425.821.3665 1 tfanspogroup.com .�.._p..,,n,: .. fY [' xIj W".

Proposed Driveway Spacing Traffic Operations Analysis The driveway level of service (LOS) was calculated based on forecast PM peak hour traffic volumes provided by the City, consistent with the City's concurrency analysis completed for the project. Original information provided by the City was revised to reflect a change in the access location from S 316th Place to split between S 316th Place and Pete Von Reichbauer Way S. Based on PM peak hour trip rates for Land Use 252 (Senior Adult Housing) from Trip Generation (ITE), 10th Edition, the 179-unit age restricted, market -rate, senior housing community is estimated to be 47 for the weekday PM peak hour. This trip generation methodology was approved by City Staff. Trips associated with the project were split between the two garage driveways based on the percentage of parking stalls accessed through each. Project trips were assigned directionally from each driveway based on the City's transportation concurrency model. Based on the allocation of parking stalls within the site, approximately 70 percent would access the proposed driveway on Pete Von Reichbauer Way S and the remaining 30 percent would access the 316th Place S driveway. Future horizon year baseline volumes were obtained from the City for the S 316th Place / Pete Von Reichbauer Way S intersection. These volumes, along with project traffic layered on top, were used to determine the traffic volumes at the proposed driveway location. The forecast turning movement volumes at the proposed Pete Von Reichbauer Way S driveway during the weekday PM peak hour are shown in Figure 2. Pete Von Reichbauer Way S Driveway 391 �15 151 �5 175 314 Figure 2. Future With -Project PM Peak Hour Traffic Volumes As shown in Figure 2, approximately 18 inbound and 15 outbound trips are anticipated to access the proposed driveway during the weekday PM peak hour. Weekday PM Peak hour traffic operations for future with -project conditions were evaluated based on the procedures identified in the Highway Capacity Manual (HCM) (2010) using the Synchro 9.1 software program. It is anticipated that the proposed Pete Von Reichbauer Way S driveway will operate at LOS B with an average vehicular delay of 13 seconds for the worst performing approach (westbound). LOS worksheets are provided in Attachment 2. Sight Distance Analysis A sight distance analysis was conducted for the proposed access location on Pete Von Reichbauer Way S by ESM Consulting Engineers. This analysis included a review of the available entering and stopping sight distance compared to City code which refers to AASHTO standards. Based on a 35-mph design speed, AASHTO standards require 250 feet of stopping sight distance and 395 feet of entering sight distance. The analysis shows that adequate sight distance is available as the sight lines extend through the adjacent intersections and meets the City of Federal Way standards. The drawing is provided in Attachment 3. Findings / Mitigation As noted in this variance request, the proposed access point is forecast to operate at LOS B. This operations analysis assumes right -turn in / right -turn out operations at the driveway. The turning restrictions are proposed in recognition of the spacing to the adjacent intersection and the activity from the driveway on the east side of Pete Von Reichbauer Way S, opposite the proposed Affinity at Federal Way driveway. The sight distance analysis shows that there is at least 395 feet of entering sight distance looking to the north for right turning vehicles, which meets AASHTO/City requirements. Based on the forecast traffic operations, the availability of the sight distance to the north, and recognition of the proposed turn restrictions, we respectfully request approval of this variance on behalf of our clients, the Inland Group. If you have any questions regarding this analysis, please do not hesitate to call or email at your convenience.
