It would be s 30' x 5' area on the Tukwila Village (not library) property. Before I check with the developer, I'm hoping to trace it back to the library's permit so that I can check with the library on whether they got the developer's permission. Derek From: Davis, Mary [mailto:Mary.Davis@seattle.gov] Sent: Tuesday, February 16, 2016 11:49 AM To: Derek Speck <Derek.Speck@TukwilaWA.gov> Subject: draft easement and drawing for electrical service for King County library at 144th St. and SR 99 in Tukwila Hi Derek, As we discussed this morning, here are the easement and drawing. I need to have the easement across a small area of the property that the City of Tukwila currently owns. I understand that the City of Tukwila will be selling this property to a private developer, but the sale has not closed yet however, the easement must be signed by the property owner of record at the time that the easement is granted. If title to this property is going to change very soon, I could possibly wait for the new owner to sign the easement, if that is easier than having the City of Tukwila sign off on it. We do not offer any compensation for the easement. It is the responsibility of the customer who needs the new service to get the necessary party(ies) to sign a distribution easement. Please let me know what works best.

We've carefully reviewed the Parking Decision that has a finding that the parking "should" be shared (not "shall") across all the parcels; therefore, if the easement contains language about "dedicated" or "reserved" stalls, then so be it. Active management of the parking and limited signage to avoid visual blight and walking hazards and confusion will be important. Thinking ahead, Bryan will be negotiating leases for each of the spaces and presumably will have language about the parking. Not sure If there will be a "lease" to the non-profit and what it will say about parking. Ultimately we want what will make all the tenants successful, including the nonprofit who will be programming the indoor and outdoor area. Thanks for including us in the email string.

Existing Development The subject site on the north side of S. 144 Street is vacant of any buildings. 40 Ave. S. a short local access street runs north south through the site and ends in a cul-de-sac that provides access to parking for an apartment building that fronts on 42 Ave. S. The subject site on the south side of the S. 144 Street contains a vacant commercial building, a separate small building that is used as a barber shop, a utility storage yard, a basketball court and accessory parking for the King County Housing Authority. Surrounding Land Use Within the north block, in the southeast corner is the existing 5,200 square foot Foster Library. The current proposal does not include any redevelopment of the existing library building. In the immediate vicinity are a number of public uses such as the high and middle schools, public pool, and a neighborhood park; a church and mosque; neighborhood retail such as drug stores, grocery store, laundromats, and dry cleaners; and a variety of food establishments. There are numerous residential uses in the area from motels, apartments to single family homes. Staff Report L13-031 Page 2 of 12 Project Description Tukwila Village is a 6.4 acre project that will straddle a two lane collector arterial and will be developed in three phases. The City of Tukwila, the property owner, entered into a Disposition and Development Agreement (DDA) giving Tukwila Village Development Associates the right to develop the property according to an approved conceptual plan. The City also approved a Development Agreement that waived certain Code requirements. Shared parking was approved as part of those Agreements. The concept of shared parking is that separate parcels of land (and therefore potential ownership) and the uses and buildings on those parcels, may share parking stalls. Shared parking allows for parking on one parcel to be used by the businesses located on a separate parcel or to allow for demand for the stalls to vary during the time of day or the seasons of the year. Within the DDA, under section 2.4 "D. Additional Approvals - The City shall have the right to require and approve easements for utilities vehicular access pedestrian access shared parking and shared maintenance for each Development Phase to ensure that the entire Development functions as an Integrated whole even if the Development Parcels and/or Development Phases come under Separate ownership and management. " Approval for shared parking is therefore not required by this decision. Attachment A shows the three phases of development. The entire project contains: • Four residential and commercial buildings with a total of 403 housing units (80 market rate apartments, 4 live/work apartments, 319 senior units;) 30,000 square feet of commercial/office space; and a 2,000 square foot community policing station. • A new 10,000 square foot King County Library System neighborhood library. • A new 4,200 square foot community building and cafe adjacent to a half acre outdoor plaza. • A total of 450 on-site structured and surface parking stalls. The site plan (Attachment B) shows parking location and totals per Phase as well as the overall site layout for buildings, driveways, and sidewalks. Phase 1 contains: Building A, which is a seven story structure, includes: • two levels of structured parking of 85 parking stalls on two separate levels and with restricted access, • approximately 8,200 gross rentable square feet of commercial/retail space and four live - work studio loft dwelling units on street level; and • five levels of 80 residential dwelling units containing a mix of studio, one -bedroom and two-bedroom apartments, and • 53 surface parking stalls and one loading stall for the library's use. Staff Report L13-031 Page 3 of 12 Building C, which is an approximate 4,210 square foot, one story community building adjacent to a 32,000 square foot community plaza, consists of a wide variety of landscaped and hardscaped areas. The community building includes: • a large flex assembly space containing approximately 1,711 gross square feet, • a catering kitchen containing approximately 368 gross square feet of space, • storage space, reception space, men's & women's public restroom space, • a cafe / coffee shop containing approximately 1,268 gross square feet of retail space, including a seating area, kitchen area, refrigeration area and office area; and • an indoor/outdoor fireplace and outdoor seating area and 11 surface parking stalls. Tukwila Library is a new one story 10,000 gross square foot neighborhood branch of the King County Library System. The total number of parking stalls provided for Phase 1 on the surface and under Building "A" is 149 stalls. Phase 2 contains: Building D, which is approximately 134,960 square feet, includes: • One level of below grade structured parking containing 49 garage parking stalls • One level of approximately 13,000 square feet of rentable commercial office space; • Five levels of residential dwelling units for seniors (70 total units) containing a mix of one -bedroom and two-bedroom apartments; and • approximately 19 surface parking stalls for commercial office use. Building E, which is approximately 134,960 square feet, includes: • 103 structured parking stalls • approximately 1,150 gross rentable square feet of commercial/retail space, and approximately 2,000 gross rentable square feet of police resource center space, • four levels of residential dwelling units for seniors (125 total units) containing a mix of one -bedroom and two-bedroom apartments, semi -private outdoor landscaped courtyard; and • approximately 11 surface parking stalls for commercial/retail use. The total parking provided for Phase 2 on Parcel D and E is 182 stalls. Phase 3, located north of S. 144 Street and adjacent and on the eastern edge of Phase 1 Building B includes: • one level of structured parking containing 86 parking stalls for residential use only and 1,800 square feet of rentable commercial/retail space, Staff Report L13-031 Page 4of12 • four levels of residential dwelling units for seniors (125 total units) containing a mix of one -bedroom and two-bedroom apartments, and • approximately 34 surface parking stalls for commercial/retail and flex use. Phase 3 parking calculation The total parking provided for Phase 3 on Parcel B is 120 stalls. II. Summary of Proposed Action 1. Parking Standard for a Use not Specified The required number of parking stalls for a Live/Work residential unit is not specified under the City's parking regulations. Under the "Uses Not Specified" section of the Off -Street Parking Chapter, (TMC 18.56.100) the Director shall determine the required number of parking stalls for uses that are not specified in the City's parking regulations. A Parking Standard Determination must be made following a Type 2 process as described in the Permit Application Types and Procedures Chapter (TMC 18.104.) The Director's Determination shall be based upon the requirements for the most comparable uses specified in the Off -Street Parking Chapter. The applicant has submitted a table showing the parking requirements by use, including the requested 1 stall per Live/Work unit. (Attachment C) 2. Complimentary Use The following definition of a complementary use is from the Tukwila Zoning Code: "A complementary use is a portion of the development that functions differently than the primary use but is designed to serve or enhance the primary land use without creating additional parking needs for the primary traffic generator. Up to 10% of the usable floor area of a building or facility may be occupied by a complementary use without providing parking spaces in addition to the number of spaces for the principal use. Examples of complementary uses include pharmacies in hospitals or medical offices, food courts or restaurants in a shopping center or retail establishments." (TMC 18.56.070 (D) Cooperative Parking Facility) For Tukwila Village the residential units are considered the primary use. The applicant is requesting that the City approve 10 % of the usable floor area from the non-residential uses be considered complementary uses and therefore not subject to the parking supply requirement. Staff Report L13-031 Page 5 of 12 3. Shared Use The concept of complementary use is that a parking space can serve two or more individual land uses without conflict or encroachment and is possible because of two conditions: • Variation in the accumulation of vehicles by hour, by day or by season at the individual land use; and • Relationships among the land uses that result in visiting multiple land uses on the same auto trip. The concept of shared parking has similarities with complimentary parking but also is used to describe two or more parcels: • with no physical separation but connected with sidewalks allowing free pedestrian movement between buildings; and • collectively satisfy the parking requirement but individually one or more of the parcels are not able to meet the Code requirements. Applications for shared, covenant or complementary parking are allowed and must be processed as Type 2 decisions per the Cooperative Parking Facility Section of the Zoning Code. (TMC 18.56.070(E.) There are no specific decision criteria for complimentary and shared parking. III. Decision Authority The purpose of the Off-street Parking and Loading regulations chapter is to provide for adequate, convenient, and safe off-street parking areas for the different land uses described in the City's Zoning Code. (TMC 18.56.010 Purpose) At the time any building or structure is erected, enlarged or at the time there is a change in its principal use, off-street parking and loading spaces must be provided as an accessory use in all zones in accordance with the requirements of the Off -Street Parking Chapter. (TMC 18.56.020 Chapter Application) The Chapter includes a table that lists the required number of parking spaces for automobiles and bicycles. The Minimum Number of Off-street Parking Spaces Table is shown on Figure 18-7 of the TMC. The table provides specific parking requirements for a number of common land uses. For example, fast food restaurants are required to have one parking stall for every 50 square feet of usable floor area and retail requires 2.5 stalls for every 1,000 square feet of usable floor area. The minimum number of parking stalls must be maintained over the life of the use. Any additional uses, either secondary or accessory in nature, must have parking available that does not impact the minimum parking of the original or primary use. (TMC 18.56.050 Required Number of Parking Spaces) Staff Report L13-031 Page 6 of 12 1. Parking for a Use Not Specified The Director's Determination shall be based upon the requirements for the most comparable uses specified in the Off -Street Parking Chapter. Comparable Uses The most comparable use for a Live Work unit is a mixed use residential unit, which has a parking requirement of one stall for every dwelling unit. The applicant surveyed the adjacent Cities of Renton and Seattle and found that their respective standard is one stall or less. The applicant submitted a Traffic Impact Analysis (Parametrix, November 2012) that references the Institute of Traffic Engineers (ITE) Parking Generation Manual, 4th Edition. The Analysis shows less than one stall per unit for the peak parking period for the residential use. 2. Complimentary Use The Director may use his/her discretion in deciding whether to grant a 10% allowance for complementary uses. This project clearly will have a dominant use, which is residential with a total of 403 residential units. The remaining floor area will be generally 15,000 gross square feet of commercial space, a 10,000 square foot library, and 15,000 square feet of office space. This area of the City is encouraged to develop with a mix of uses. The types of uses are such that there is an expectation that site users will use more than one "business" while on the site. For example, on office worker will get lunch at a restaurant, a resident will visit the library, a customer will go to more than one store. 3. Shared Parking The Director may use his/her discretion in deciding whether to grant approval for shared use of parking. The proposal for the project is for the proposed six lots (A, B, C, D,. E and the Library Parcel) to share the parking available throughout the five lots (A, B, C, D and E.) No criteria exist for the decision maker other than an assumption that the ability to share remains and works for the life of the project. Assurance can be given via reciprocal easements over the five lots for the users of the six lots. The City of Tukwila owns the property that will be sold to Tukwila Village Associates, LLC and to the KCLS. The Project has been envisioned as a mixed use project that functions as a whole. There are many references both within the DDA and the Development Agreement to sharing driveways, parking and other amenities and accessory uses in order to obtain a high-quality, pedestrian oriented development. Staff Report L13-031 Page 7 of 12 Comprehensive Plan Policy A related policy from the Comprehensive Plan: 1.8.8 Encourage facilities and improvements that support transit use in new development, redevelopment, and street projects. The Tukwila City Council made the following findings during their deliberations on the Tukwila Village Development proposal. Within the Development Agreement is the following: 1. "Goal 8.2.22 of the City s Comprehensive Plan provides for the establishment of an overlay district in the designated urban renewal area generally between South 140'x' Street, 42nd Avenue South, South 146th Street, and 37th Avenue South that may allow increased building heights, reduced residential parking requirements, and other alternative development standards subject to specific criteria, in order to encourage well designed compact transit oriented and pedestrian friendly redevelopment to activate the community along Tukwila International Boulevard." 2. "The adoption of supplemental development standards and criteria providing for taller building heights and reduced parking requirements was intended to make urban densities and amenities more likely while the impact upon residential areas resulting therefrom would be lessened by requiring development along Tukwila International Boulevard, more significant structured parking and pedestrian friendly amenities;" Engineering Analysis Within the Traffic Impact Analysis prepared by Parametrix (May 2013,) (Attachment D) is a description (pages 14-16) on peak parking demand. The author cites the Institute of Traffic Engineers (ITC) Parking Generation Manual. The analysis does not consider the phasing of the uses but instead considers the uses in total. The peak parking demand analysis (Table 9) is not absolutely relevant because the parking supply is not completely shared. All the parking for the residential units is within the garage spaces, which are not accessible to the commercial use customers; however, excess stalls are available for employees in some of the secured garage areas. This employee parking, when not in use by the employees during the evening and on weekends, will be available for "overflow" parking demand. Among the other uses — retail space, library, office and community policing — the estimated peak parking period would be noon during a weekday. The authors did not consider weekend parking demand. The higher amount of office space relative to the commercial space, which has a peak parking demand during the week mid-morning, relative to the commercial, which has a peak during mid- day, provides a greater opportunity for sharing to occur because of the difference in the peak demand periods. Of note, the Parametrix report states that although they did not analyze internal capture rates between the uses that they typically estimate a 10% internal capture rate. That means that 10% of the parkers on site typically will use more than one use without using their car for another trip. Staff Report L13-031 Page 8 of 12 Phasing Plan and Parking Supply Because this is a large project that will be built over two — three years, (Attachment E) staff considered the implications of parking demand and supply during the phasing period. Attachment F shows that parking supply requirements, per the Zoning Code, are not evenly distributed between the five lots — hence the need for a shared parking decision. The applicant respond with the following solutions. (Attachment G) Phase 1 has the largest deficit of spaces. The Phase 1 - 73 stall deficit - becomes reduced by a 30 stall surplus produced by Phase 2 completion on the south side of S. 144 Street. Phase 3 completion brings the project into compliance and creates a 2 stall surplus. To mitigate the temporary Code shortage, the applicant discusses the construction of 18 on -street parking stalls in S. 144m Street, which is to be completed as part of Phase 1; their proposal to have temporary parking on proposed Lot B that would be available upon Phase 1 completion (Attachment H;) and the seven month absorption period for Phase 1 residential units and 17 month absorption for all the commercial space in Building A. The currently proposed completion of Phase 2 is within five months of the completion of Phase 1 and Phase 3 is within 12 months. It is not until all three phases are built that the project will meet the requirements of the Parking Code. In the end, at full build -out, the project meets the Code requirements for parking supply. Per the DDA, the City as property owner, must approve a phasing plan for development and can consider any parking issues related in the long term to a phase plan of development. (See Section 2.4 of the DDA Phasing; Development Parcels) Parking Supply Alternatives Transportation options Two Metro Bus Routes provide immediate access to the site. Route 128 stops on S. 144 Street and travels approximately every 15 minutes between West Seattle and Southcenter and serves the Light Rail station. Route 124 stops on Tukwila International Blvd (TIB) and travels approximately every 15 minutes during peak periods between the Light Rail station at Southcenter Boulevard and downtown Seattle. The intention of the requirement for a Transportation Demand Management Plan (discussed below) is to assist site residents and users in taking these transportation alternatives. Transportation Demand Management The project is within the Urban Renewal Overlay District and the developer has chosen to utilize the standards of the overlay zone. Those standards come with a requirement to submit a Transportation Management Plan, with is a transportation demand management tool. The Code says, "The property owner/manager shall prepare a Transportation Management Plan (TMP) to encourage alternatives to automobile use, and that provides each residential and commercial tenant with materials that may range from offering information about transit and Staff Report L13-031 Page 9 of 12 bicycle options to providing transit tickets and passes." (TMC 18.43.070 Specific Urban Renewal Overlay Development Standards and Criteria) The City routinely administers TMPs through its Commute Trip Reduction Program, which is a program focused on sites with 100 or more employees. It is unlikely that this project will have an employer who is an "affected employer;" however, the CTR program could provide a framework for guiding and administering the transportation management plan for the site. Conclusions 1. Parking Standard for Live/Work Parking supply is per the City standards for all the residential units except the live work, for which there is no standard. The parking standard of one stall per Live/Work unit is comparable or exceeds the standard of adjacent jurisdictions and is consistent with the national standard per the ITE manual. 2. Complimentary Parking This large scale mixed use development is an exemplary project for demonstrated the potential to reduce vehicular trips. The ability to walk between multiple businesses or from home to business is the purpose of complimentary allowances. The design guidelines and standards for the area are created to encourage pedestrians to walk between buildings and uses and not to view the properties and their uses as isolated stand-alone fixtures in the neighborhood. Approval for the 10% complementary parking reduction is appropriate given the range of uses on the site, the differing peak parking demand periods as discussed in the Transportation Analysis and the potential for the internal capture of trips on the site. In addition, on -street parking will be available on the western half of the S. 144 Street block as part of Phase 1 street improvement. On street parking is currently available around the corner on 42 Avenue S. The parking on 42 Avenue S. however is not visible or obvious to visitors who are not familiar with the neighborhood. Surface lots across TIB that serve commercial business will be obvious, which may result in some unsanctioned off-site parking. 3. Shared Parking Staff has reviewed the parking by phases and determined that when the development is complete, the project will meet the Zoning Code requirements for parking per the decisions above. Parking demand for special events could create a greater demand than supply. King County Library System (KCLS,) and the nonprofit organized to market and schedule the community space events, are users who will potentially have events that generate higher demand than currently considered. They will need to be involved in an association that coordinates the parking demand for all the site users. Staff Report L13-031 Page 10 of 12 Users should be allowed access to all surface parking in order to maximize the site's flexibility to meet the variable needs throughout the day or a week. Sharing of some of the secure parking may also need to occur to balance the parking needs/demands across all five parcels or to provide overflow parking during special events. In order to manage the needs, the Transportation Management Plan will be a useful tool, and the administrator of that Plan, will play an important role in parking for the site. Circling and extra exiting/entering movements on City streets could occur if the parking is full on either the north or south side of S. 144 Street. Informational signage for parking could assist with this way finding need. In order to assure shared parking is available in perpetuity, reciprocal access and parking easements will be recorded against the five proposed lots. Staff's analysis of the phasing plan shows that a deficit of parking may occur depending on the absorption of the newly built space. The applicant also anticipates this parking variability by phase and shows an option for temporary parking on proposed Parcel B is developing on -street parking within the S 144 Street right of way and identifies the possibility of approaching surrounding property owners, such as the KCLS or the Tukwila School District, for use of their off-site parking when available. The deficit of parking stalls due to the phasing of the development shall be addressed by the Development Phasing Plan approved per the Disposition and Development Agreement. Any temporary parking approved as part of the phasing plan shall be required to obtain all applicable permits; comply with surface and storm water management requirement; and address maintenance and performance measures. Recommendation 1. Approve the application for a parking standard for the live/work units of one space per unit; 2. Approve a 10% complementary use allowance; 3. Approve shared parking across proposed parcels A, B, C, D and E subject to the following conditions: Prior to issuance of the construction permits for Phase 1, the applicant shall: a) Modify Boundary Line Adjustment/Lot Consolidation application (Land Use File # L13-021) to include reciprocal parking access and maintenance easements across all lots. b) Adhere to the relevant procedures of the City's Commute Trip Reduction Program (Tukwila Municipal Code 9.44,) in order to implement the required Transportation Management Plan. The Tukwila Village Development Associates, LLC and its successor, shall perform the role of Employee Transportation Coordinator (ETC) Staff Report L13-031 Page 11 of 12 and perform that role for all businesses on the Tukwila Village site. This role shall include providing information and incentives for alternatives modes of transportation such as transit, carpool etc. Annual reports of the efforts and results shall be provided to the city's CTR coordinator. The Tukwila Village Project site includes proposed parcels A, B, C, D, E and the Library parcel (Library Parking Standard Land Use File No. L13- 021.) c) Information signage shall be developed in accordance with the City's Sign Code (TMC 19) and submitted for review and approval as part of the design review application for Phase 3. d) Any temporary parking approved as part of the phasing plan shall be required to obtain all applicable permits; comply with surface and storm water management requirement; and address maintenance and performance measures.

Pass -by trips are trips to/from sites where the vehicle was already on the street and as it is passing by the site, the driver turns into the site to make a stop before resuming their original trip. New trips are the remaining trips, where the primary purpose of the vehicle trip was to travel to and from the site. Only the 17,000 SF of retail uses are expected to attract pass -by trips. The pass -by trip reductions applied to the retails uses were as follows: . • 65 percent for the PM peak hour (based on the regression equation found for Shopping Center in the ITE Trip Generation Handbook), • 55 percent for daily (although no data exists, it has been assumed to be somewhat less than during the peak hours), and • 65 percent for the AM peak hour (although no data exists, it has been assumed to mirror the PM peak hour trend). The regression equation was used rather than the average pass -by percentage because the pass -by data for shopping centers indicate that the pass -by rate exponentially increases as the square footage of the retail decreases. This presumably occurs because larger shopping centers are more of a regional destination rather than a local neighborhood center, where someone might drop by on the way home in the evening or to the office in the morning (i.e., a pass -by trip). The result of applying the above pass -by rates to the external trip generation for the retail uses is summarized in Table 6 below.

Trip Distribution and Assignment Based on the land use patterns in the general vicinity of the project, knowledge of the local transportation system, professional engineering judgment, and traffic counts along Tukwila International Boulevard, distribution and assignment of the project trips were estimated. The new project trip distribution is shown on Figure 4. New trips are estimated to travel to/from the site in the following pattern: • 25 percent to/from the north on TIB towards Seattle. • 25 percent to/from the west on S 144th Street towards nearby neighborhoods and Military Road S. • 25 percent to/from the east on S 144th Street towards nearby neighborhoods. • 25 percent to/from the south on TIB towards the City of SeaTac and State Route 518. Pass -by traffic to/from Tukwila Village is shown on Figure 5 and was assigned based on where the uses were located on the site as well as the volume being carried in the future baseline 2016 traffic streams on TIB and S 144th Street, which indicated the following distribution for the Phase 1 pass -by trips, which are likely to arrive from both TIB and S 144th Street: • 43 percent from southbound TIB Tukwila Village Development Associates LP . 554-6892-001 Traffic Impact Analysis 10 November 12, 2012 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) • 26 percent from northbound TIB • 17 percent from westbound S 144th Street • 14 percent from eastbound S 144th Street For Phase 2 pass -by trips, the uses are set -back from TIB and much more likely to draw traffic only from S 144th Street. Given that, the Phase 2 pass -by traffic was distributed as follows: • 54 percent from westbound S 144th Street • 46 percent from eastbound S 144th Street Lastly, because the project site provides non -motorized system improvements in project vicinity, crosswalk volumes were projected to increase by 50 pedestrians per hour with the completion of the project. For comparison, 50 pedestrians per hour represents the difference between the values suggested for assuming the number of pedestrians per hour in a rural area (zero pedestrians per hour) and a suburban area (50 pedestrians per hour). These values were documented in in the National Cooperative Highway Research Program (NCHRP) Report 599 — Default Values for Level of Service and Highway Capacity Analyses. The thought being the relative difference reflects the change from an undeveloped condition to a suburban development condition.

The proposed site uses were matched as close as possible to the data available. The parking demand estimates were compared to the • proposed parking supply. A total of 431 parking stalls would be provided on-site of which 293 would be in - building (garages) and 138 spaces would be surface parking stalls. Additionally, 23 on -street parking spaces would also be provided. Table 8 below summarizes the anticipated parking demand for a typical weekday. Table 8.

Table 9 illustrates this by summarizing the parking demand as it varies throughout the day using data from ITE.

Therefore, the assumed daily distribution for family apartment units was used. 3 For the retail uses, the daily distribution of parking demand for Shopping Center (ITE Land Use 820) for a non -Friday, non - December weekday was used. To account for live-in tenants at the live/work spaces, 9 percent of the peak parking demand was assumed, which amounts to 6 parking spaces and is equivalent to an increase of 4 apartment units generating additional overnight parking demand from 10:00 PM to 7:00 AM. 4 Used data for Library (ITE Land Use 590). 5 Used data for Medical -Dental Office Building (ITE Land Use 720). 6 Used data for Government Office Building (ITE Land Use 730), which provides data for the time period from 9:00 AM to 4:00 PM. That was supplemented with data from Office Building (ITE Land Use 701) for the hours from 7:00 AM to 9:00 AM and 4:00 PM to 7:00 PM. Tukwila Village Development Associates LP 554-6892-001 Traffic Impact Analysis 16 November 12, 2012 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) Note that the above parking demand estimates have not been adjusted for the mixed-use nature of the site and the internal capture between uses, which would reduce the peak parking demand. The daily trip generation would experience a trip generation reduction of 10 percent due to internal capture and a similar reduction would likely occur for the peak parking demand. One other factor that may reduce the overall parking demand is the close proximity to King County Metro bus stops on Tukwila International Boulevard and S 144th Street in the site vicinity (see the Transportation System Conditions section for detailed information about the routes and stop locations). With the overall site peak parking demand peaking at 281 parking spaces, and 431 on-site parking spaces being provided, the proposed parking supply would be adequate. TRANSPORTATION SYSTEM CONDITIONS Street Descriptions The street characteristics in the project vicinity along the project frontage are described in Table 10. Table 10. Existing Street Characteristics in Project Vicinity Street Name Functional Classification Tukwila International Boulevard S 144th Street Principal Collector Posted Speed Limit 40 mph 25 mph Travel Lanes Two through lanes in each direction with left -turn lanes and right -turn pockets at S 144th Street.

Signalized crosswalks are provided at the east and west legs of the TIB/S 144th Street intersection. An unsignalized mid -block crosswalk with overhead flashing beacons is also provided north of S 144th Street across TIB. West of TIB, there are sidewalks and bike lanes on both sides. East of TIB, there is continuous sidewalk along the north side and intermittent sidewalk along the south side. There are no bike lanes currently along either side. Signalized crosswalks are provided at the north and south legs of the TIB/S 144th Street intersection. An unsignalized crosswalk is also provided at the east leg of the S 144th Street/41 st Avenue S intersection. Transit Service Options Bus stops for King County Metro Route 124 are located on the east side of TIB north of S 144th Street and on the west side of TIB south of S 144th Street. Metro Route 124 operates on 30 -minute headways on weekdays and connects to both SeaTac and downtown Seattle. Bus stops for King County Metro Route 128 are located on the north side of S 144th Street east of 42nd Avenue S and on the south side of S 144th Street west of TIB. Metro Route 128 operates on 30 -minute headways on weekdays and connects Tukwila to West Seattle. Crash History The five-year history of vehicle crashes in the project vicinity was reviewed to see if the crash rate appeared to be unusually high. None of the locations studied experienced crash rates in excess of 1.0 crash per million entering vehicle. In other words, the crash rates were less than one in million. Additionally, no crashes were severe enough to cause fatalities. Table 11 summarizes the five-year crash history.

The quality of traffic operations at intersections was ranked with a level of service (LOS) on an alphabetic scale from LOS A to LOS F, with LOS A being the best operations and LOS F being the worst operations. This is consistent with the Highway Capacity Manual published by the Transportation Research Board. The deterministic software, Synchro version 7 (Build 773, Revision 8), developed by Trafficware, was used to study the intersection operations. Using the intersection traffic volumes shown on Figures 2, 3, and 6, the LOS results were obtained and are summarized in Table 13 below. Table 13. Intersection Level of Service Conditions Existing 2012 Future 2016 Baseline Future 2016 with Project Intersection LOS Delay LOS Delay LOS Delay Tukwila International Boulevard at C 35.0 D 36.1 D 38.9 S 144th Street S 144'" Street at 41st Avenue S/East Drive Northbound Approach B 13.1 B 13.3 C 23.5 Southbound Approach B 12.1 B 13.2 C 23.9 Tukwila International Boulevard at at North Drive (Westbound Approach) Tukwila International Boulevard at at Main Drive (Westbound Approach) S 144m Street at South Drive (Northbound Approach) A 8.9 A 9.0 C 19.4 None of the intersections operate worse than LOS D. With Tukwila Village, the intersection LOS would degrade from LOS B to LOS C, however, LOS C is still an acceptable LOS. As identified in the City of Tukwila Comprehensive Plan, the LOS standard is LOS D in residential areas and LOS E in commercial areas. Therefore, all of the study intersections would meet the LOS standard and no specific mitigation is recommended to improve the LOS condition at the study intersections. Driveway Channelization The proposed driveways operate at acceptable LOS with the channelization shown on'the site plan. The Tukwila Infrastructure Design and Construction Standards do not contain specific channelization guidelines to follow for evaluating channelization proposed at driveways beyond LOS conditions, but do mention the City recognizes and uses the most current edition of A Policy on Geometric Design of Highways and Streets by the American Association of State Highway and Transportation Officials (AASHTO) for channelization guidelines. AASHTO does not have quantitative guidelines for recommending right -turn channelization and the City's standards indicate that the City recognizes the WSDOT Design Manual as a reference, which does have quantitative guidelines for right -turn channelization, therefore, that has been used to supplement the AASHTO reference. The greatest potential need for left -turn channelization on a public street to serve movements into the project site would occur at the S 144th Street/East Drive/41st Avenue S intersection. In reviewing the AASHTO guidelines and extrapolating for a 30 -mph operating speed, the combination of left -turn volumes, advancing and opposing volumes at the East Drive intersection do not warrant the a left -turn lane. The greatest potential need for right -turn channelization on a public street to serve movements into the project would occur at the TIB/Main Drive intersection. At this intersection, 62 vehicles would turn into the Main Drive with 526 vehicles traveling advancing northbound behind them. However, there are two northbound travel lanes Tukwila Village Development Associates LP 554-6892-001 Traffic Impact Analysis 19 November 12, 2012 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) and the posted speed limit is 40 mph there. The WSDOT Design Manual only recommends using the Design Manual Exhibit 1310-19 in developing recommendations for right -turn lanes when multilane faeilities have posted speed limits of 45 mph or greater. Additionally, given that King County Metro has a bus pull-out in close proximity that would conflict with a right -turn lane, no right -turn lane is recommended on TIB at the Main Drive. Driveway Sight Distances The sight distance exhibits prepared by Barghausen Consulting Engineers indicate that the proposed driveway locations would have adequate sight distance per City standards. Therefore, no sight distance improvements are recommended. It is recommended that sight distance triangles be regularly maintained. Driveway Access Spacing & Corner Clearances The proposed driveways were located based on site constraints and access spacing and corner clearance requirements. Note: The East Drive/41st Avenue S was not checked because it exists in that location today. Table 14 summarizes the distances between intersection corners and accesses. Table 14. Access Spacing and Corner Clearance Access North Drive Corner Clearance 530 feet edge to edge from TIB (560 feet centerline to driveway center) 70 feet edge to edge from S 142nd Street (110 feet centerline to driveway center) Access Spacing 270 feet edge to edge from Main Drive Main Drive 230 feet edge to edge from S 144th Street (260 feet centerline to driveway center) 270 feet edge to edge from North Drive South Drive 140 feet edge to edge from TIB (195 feet centerline to driveway center) 180 feet edge to edge from East Drive/41st Avenue S MITIGATION FEE REQUIREMENTS Mitigation fees are due to the City at the time of building permit issuance to pay for the project's proportionate share of impacts. Additionally, the proposed development must pass the concurrency test conducted by the City of Tukwila. CONCLUSIONS & RECOMMENDATIONS The proposed Tukwila Village would not create significant adverse impact on the transportation system. The primary recommendations are: • Maintain clear sight triangles • Pay for the project's proportionate share impacts via the City's traffic impact fee program Tukwila Village Development Associates LP 554-6892-001 Traffic Impact Analysis 20 November 12, 2012 TUKWILA VILLAGE Revised PHASED DEVELOPMENT PLAN 10/04/2013 PROPOSED PHASED DEVELOPMENT SCHEDULE PHASE PHASE 1: PHASE 2: PHASE 3: Milestone Target Date Design Review Application Submittal 06/01/2013 Design Review Approval 10/31/2013 Grading & Foundation Permit Application Submittal 11/01/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 11/01/2013 Building Permit Application Submittal 12/01/2013 Grading & Foundation Permit Issuance 02/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 02/01/2014 Commence Grading, Foundation & Engineering Work 02/15/2014 Building Permit issuance 04/01/2014 Commence Building Construction 05/01/2014 Construction Completion / Issuance of Certificate of Occupancy 04/30/2015 Design Review Application Submittal 11/01/2013 Design Review Approval 01/31/2014 Grading & Foundation Permit Application Submittal 02/01/2014 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 02/01/2014 Building Permit Application Submittal 03/01/2014 Grading & Foundation Permit Issuance 05/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 05/01/2014 Commence Grading, Foundation & Engineering Work 05/15/2014 Building Permit Issuance 07/01/2014 Commence Building Construction 08/01/2014 Construction Completion / Issuance of Certificate of Occupancy 09/30/2015 Grading & Foundation Permit Application Submittal 11/01/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 11/01/2013 Grading & Foundation Permit Issuance 02/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 02/01/2014 Commence Grading, Foundation & Engineering Work 02/15/2014 Design Review Application Submittal 07/01/2014 Design Review Approval 09/30/2014 Building Permit Application Submittal 12/01/2014 Building Permit Issuance 04/01/2015 Commence Building Construction 05/01/2015 Construction Completion / Issuance of Certificate of Occupancy 04/30/2016 4> JOHNSON BRAUND INC RECEIVED 272013 September 18, 2013 Revised September 27, 2013 Moira Carr Bradshaw Senior Planner City of Tukwila / Department of Community Development 6300 Southcenter Boulevard Tukwila, WA 98188 RE: TUKWILA VILLAGE PHASE ONE B.A.R. PARKING COMMENTS SEP C;C)MFJIUNI 1 Y nEVLLUPMLNT Moira, Please see our responses in italics below to the parking comments dated August 07, 2012. Per our previous phone conversations about parking calculations, the attached parking summary has been revised to utilize the complimentary uses parking reduction as outlined in the Tukwila Zoning Code section 18.56.070.D. In addition to the complimentary uses we've also noted a request for a 5% administrative variance for the portion of the site north of S. 144th street only. Justification for the requested variance includes on -street parking stalls provided on 144th, walkable development with a large number of residents within the project itself and surrounding residential/multifamily neighborhood and the close proximity to available transit. 1. Parking standard for live work Applicant proposes 1.5 per unit - Is there any experience, documentation or support for this proposed standard? City of Seattle parking standard for Live -Work units (SMC 23.54.015 Table A- see attached) is 0 spaces for 1,500 sf or less and 1 space for units 1,500 sf to 2,500 sf. City of Renton parking standard for Live -Work units (RMC 04-04-080 — see attached) is a minimum and maximum of one per unit. (See also attached City of Renton staff report/recommendation for parking of Live/work units based on area of unit <2,500 sf = 1 stall.) The proposed Live -Work units in Building A are 465 sf on the ground floor and 200 sf on the mezzanine level = 865 sf total. We had originally calculated the residential portion of the unit at 1 stall per unit (1 bedroom) + an additional .5 stall for the non-residential portion, however given the precedent of other local jurisdictions with live -work parking quantity based on overall unit size, we propose reducing our parking to one stall per unit. See revised parking calculations attached. 2. Assumption on usable floor area Parking requirement is based upon definition of "Usable Floor area" which means that part of the floor area of any structure which is actually used from time to time for any commercial purposes, such as a sales area, display area, walkways or storage area. 15200 52nd Avenue South, Suite 300, Seattle, Washington 98188 Phone 206.766.8300 www.johnsonbraund.com ARCHITECTURE INTERIOR DESIGN Page 2 September 17, 2011 Parking calculation shall not include: • common corridors designed for the circulation of people at nonretail establishments, • restrooms, • elevator shafts and stairwells at each floor, • mechanical equipment rooms or attic spaces and • exterior covered loading docks. (TMC 18.06.863 Usable Floor Area) Please provide support for use of the 75% as a useable floor area per the definition above. The parking calculations have been revised to reflect a higher percentage of useable area. In reviewing the area of each tenant space and the anticipated use/layout (i. e. many of the small incubator space will simply have accessible unisex restroom) it was determined that the useable areas of the incubators spaces will be approx. 85-90% useable and the restaurant areas 80-85% useable. We have utilized the higher usable area in the parking calculations: 90% for general retail uses and 85% for restaurant uses. See revised parking calculations attached. 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? See attached response from Parametrix dated 8-23-2013. 4. How will impacts to parking from community events be managed? Parking for community events will be managed by flexible/ shared parking between phases. After business hours (5 pm) and on weekends the surface parking behind Building D (19 stalls) and on the access driveway between D & E (11 stalls) will be available for use. The on -street parking (18 stalls) is also available for event use at all times during the day (total of 48 additional stalls). We have now planned for a mezzanine level of parking in the garage of Building E. This will allow for an additional 25 stalls to be available on the main floor garage level for overflow/flexible use for Tukwila Village as needed. Page 3 September 17, 2011 When large events are planned (in evenings and/or summer months), valet parking may be utilized and arrangements may also be made with Foster High School to allow for overflow off-site parking. 5. Please verify that housing occupants will be charged for structured parking. Have you anticipated on-site or off-site impacts and how they will be managed? Some of the housing occupants will be charged for structured parking based on affordability levels. The low-income senior units in Buildings D & E and the low- income/ affordable portion of the mixed -income units in Buildings A & B will not be charged for structured parking. The market rate units in Buildings A & B will be charged for structured parking. All residential tenants must register to park on site (either in a structured parking garage stall or a surface parking stall). No surface parking stall registrations will be allowed for residential tenants (with the possible exception of a reasonable accommodation under Fair Housing laws). The Developer's captive management company will monitor the use of garage parking stalls and surface parking stalls. If a residential tenant's vehicle is not registered or is parked in a surface stall, it will be towed. 6. Discuss the impact of reserved parking. Which stalls will be reserved, how will they be managed and show how will it affect the overall supply relative to demand. The 11 surface parking stalls + 1 loading stall located immediately to the north of the Library will be reserved for the Library use only. The stalls located off of T.I.B. adjacent to Building A and the surface stalls located immediately south of the Building A commercial frontage will be reserved for Building A commercial / retail customers. Several stalls in the parking garage of Building B will be reserved for use by employees of the commercial / retail tenants in Buildings A, B and C. Since the Library and commercial tenants of Building A are the largest/most constant uses for the project, reserving these stalls for these uses will not adversely affect supply relative to demand. There are 18 stalls west & south of Building E that are reserved (pursuant to an existing parking easement, to be amended) for the adjacent King County Housing Authority project (Riverton Terrace.) 7. Will the structured parking be assessable to office/retail/library tenants? The structured parking is to be secured with locked gates and controlled access cards. Building A garage is reserved for residential tenants only. All of residential parking for Building B is provided in the garage. Building B garage also has 16 additional stalls available for employee parking (employees from Building A, Page 4 September 17, 2011 B, and C) and 2 stalls for car-share/flex car parking. The employee parking will also be access controlled. Building D parking garage serves all of the residential tenants as well as a percentage of the Building D office tenant employees. Building E garage serves all of the residential tenants as well as the parking for the Neighborhood Police Resource Center and a percentage of the office tenant employees from Building D. Twenty five (25) additional parking stalls will also be available for overflow/special events parking on the main garage level. 8. Show how the phasing of the project and of the parking supply will affect parking demand. For example, if all of the calculations are accurate and supportable for Phase one, then the parking demand is 190 and yet only 150 are proposed for Phase one. My understanding is that 33 stalls on Parcel B could be made available in a temporary condition. There are issues of: • the code requirement that stipulates: The surface of any required off-street parking or loading facility shall be paved with asphalt, concrete or other similar approved material (s) and shall be graded and drained so as to dispose of all surface water, but not across sidewalks (TMC 18.56.040 (7) (a.) General Requirements. • the impact of construction of Building B and the temporary elimination of the 33 stalls. If the above points can be adequately resolved, please address any deficit from the standard of stalls. Phase 1 requires 190 stalls + 1 car share + 2 loading stalls. 100 of the stalls are for residential tenants and 93 are for commercial uses. Phase 1 provides 149 stalls total as follows: Parcel A/Phase 1: 85 garage stalls (for residents), 51 surface stalls and 2 loading stalls. Parcel C/Phase 1: 11 surface stalls. Until Phase 3 is constructed, the parking demand is short 44 stalls. 34 stalls will be made available on Parcel B in a temporary parking condition. The additional 10 required stalls can be satisfied by the available on -street parking stalls on the north side of S. 144th street (13 total). Disruptions to available parking on Parcel B during construction of Phase 3 can be offset by flexible shared uses with Phase 2. This includes 5 additional on -street parking on the south side of C. 144th street , as well as the overflow/shared event parking in the garage of Building E (25 stalls). Page 5 September 17, 2011 9. Please explain the sequence of the S 144 Street improvements and the potential availability of those on -street stalls. The construction schedule of the S 144`h street improvements is contingent upon the approval of a Transportation Improvement Board Grant application. However, the intention is that the north half of the street improvements will be completed with Phase 1 and the south half of the street improvements will be completed with Phase 2.

Consistency with GMA, the Plan, and Countywide Planning Policies This proposal is consistent with the GMA, Comprehensive Plan, and Countywide Planning Policies. Providing the live -work unit option in the CN and R-14 zones is consistent with policies of having a mix of uses and mixed-use structures spread throughout urban areas where people can both live and work and where services can be provided in closer distance to surrounding neighborhoods. Effect on critical areas and natural resource lands There is no foreseen effect on critical areas and natural resource lands. If there are such impacts with a live -work use, an environmental evaluation would be part of a project's review. Effect on other considerations None. Staff Recommendation Staff recommends that live -work units become a new use allowed in the CN and R-14 zones with the following standards: • Non-residential spaces in the units must meet commercial building standards so the space can be used for small scale business activity over the long term and fulfill the purpose of live -work, where a service is provided. • Live -work units should not be a permitted use outright, but should instead be processed through an Administrative Conditional Use Permit so conditions can be established based on local circumstances. • For the R-14 zone, live -work units should only be allowed along arterials (principal, minor, and collector) rather than allowed throughout the residential zone. This arterial criteria would limit the areas where a small business could receive clients and deliveries without negatively impacting residences. • A design standard should be required where the non-residential/business space should create a pedestrian oriented area. •j Parking requirements for live -work units should at minimum require one parking space, specifically for the residential space. For units 2,500 square feet or less, this one space would be the requirement for the whole unit. For units greater than 2,500 square feet,) required parking would be based on the parking standards for the non-residential use or, the closest similar use as determined by the Administrator.; Implementation Requirements Sections in the Development Regulations (Title IV) of the Renton Municipal Code would need to be changed including: creating a definition for live -work unit, adding live -work unit to the zoning use table, and establishing requirements that live -work units only be allowed adjacent to arterials in the R-14, and that the business/non-residential spaces are pedestrian oriented along the street and sidewalk. #D -I 1 Page 3 of 3 March 11, 2009 Parametrix ENGINEERING . PLANNING . ENVIRONMENTAL SCIENCES August 23, 2013 Parametrix Responses Comment 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? Responses First Bullet: The primary intent behind using Shopping Center (Land Use 820) is that it permits the site to be flexible in offering leases to variety of tenants without having to have the exact commercial land uses identified as long as they fall within the uses listed under shopping center. Additionally, each of the commercial uses may peak at different times of the day and ITE does not have hourly variations in parking demand data for all these potential land uses. For example, a lunch -oriented deli may peak midday, but a dry cleaners may peak first thing in the morning and in the evening, but have little parking demand in the middle of the day. This helps prevent over -building parking and unnecessarily increasing impervious surface area. Second Bullet: The peak parking demand characteristics from ITE for Low/Mid-Rise Apartments shown are based on a formula rather than a rate. The formula is P = 1.42x — 38, where P is the peak period parked vehicles, x is the number of dwelling units, and -38 spaces (or vehicles) is the y -intercept of the formula. Based on the information in ITE Parking Generation, the formula is the most appropriate means estimating parking demand (the coefficient of determination, R2 , is 0.93, which indicates good correlation with the data). Third Bullet: The community assembly space in Bldg. C is included with the Shopping Center space. Shopping Centers often include assembly/gathering space for art festivals, fashion shows, and other community gatherings. The average parking demand for the community assembly space could be estimated as approximately 25 percent of the overall parking demand for shopping center. m Deficit/Surplus Parking Provided co N O N co N N Lfl lD m 0 LF � N 0l 1)1 N O O O O O N O O e-4 O O O O O Lfl N O 0 0 W N m N O N N O Lfl 0 0 O Ol t- 4 Useable Floor 03 L c CO tD m Lfl v 03 N O 0 0 W Y c 4) N a) CC Restaurant Fast Food less 118 ufa of outdoor c > o E E E a, Vf 0_ u ra 7, L c u 4) E JU 00 m 00 CO u 00 m 4' O fh C C aC W a m CO lD m N m r-1 m O O O N 0 O O O Lfl .-i N m Cr) 0 O Lfl m r-1 Lfl m 0 '--I LLJ (RS 0 00 m 4' v cc 00 fo (NI W H H ui LL 0 0 N 00 lD dr 00 S. 144 Street. 13 north side 5 south side New Street Parking POTENTIAL rn N N N.

' // Z6/49 SDA Section 2.4 Phasing; Development Parcels. A. In General. Developer shall have the right to develop the Property in multiple Development Phases to facilitate financing and ownership, to aid in the timing of and sequencing of construction, and to attain flexibility to adjust to market demand and other factors. In the event that Developer intends to develop the Property in multiple Development Phases, Developer shall submit its plan for phased development to the City (the "Phased Development Plan") for its review and approval prior to, or contemporaneous with, submittal of its proposed BLA application to the City. The Development Parcels that are associated with each Development Phase, including the Plaza Parcel, may be owned, operated and managed separately, although initially developed under the control of Developer or an Affiliate. B. City Review and Approval. The City shall have the right to review and approve the Phased Development Plan, including the development of the Plaza Parcel, for the purpose of ensuring compliance with this Agreement and to ensure that the Additional Development Work associated with each proposed Development Phase, as described at Section 5.2 of this Agreement, will fully support the Improvements associated with each Development Phase in the event that future Development Phases are delayed or not completed by Developer. The Phased Development Plan shall include and identify: 1. A summary of the site plan and design review elements listed in Section 2.3 (Site Plan and Design Review Submittals) to be included within each Development Phase; 2. A proposed Construction Schedule and sequencing for the acquisition of the affected Development Parcels and development of the Improvements for each Development Phase, including Developer Additional Work associated with each Development Phase (e.g., infrastructure improvements, utilities, driveways and Landscaping). C. Plaza Parcel; First Development Phase. Developer shall develop the Plaza Parcel contemporaneously with, and as part of, the development of the first Development Phase. D. Additional Approvals. The City shall have the right to require and approve easements for utilities, vehicular access, pedestrian access, shared parking, and shared maintenance for each Development Phase to ensure that the entire Development functions as an integrated whole even if the Development Parcels and/or Development Phases come under separate ownership and management. E. Library Parcel; Timing. The City shall use its best efforts to require the KCLS to submit a proposed site plan with respect to the Library Parcel and a conceptual architectural design for the proposed library branch building by the time Developer submits a design review application for the first Development Phase. This is to ensure the City and Developer have information on how the site plan and the architectural design for the proposed library branch building will be compatible with the overall Development, and in particular, the Improvements on the Development Parcels adjacent to the Library Parcel. 1.5 TUKWILA VILLAGE PHASED DEVELOPMENT PLAN PROPOSED PHASED DEVELOPMENT SCHEDULE PHASE Milestone PHASE 1: PHASE 2: PHASE 3: Target Date Design Review Application Submittal 6/1/2013 Design Review Approval 9/30/2013 Grading & Foundation Permit Application Submittal 10/1/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) ‘ 10/1/2013 iikcil g Perm t Application Submittal::` O1/1/2013,?/ Grading & Foundation Permit Issuance 1/1/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 1/1/2014 Commence Grading, Foundation & Engineering Work 1/15/2014 Building Permit Issuance 3/1/2014 Commence Building Construction 4/1/2014 Construction Completion / Issuance of Certificate of Occupancy 3/31/2015 Design Review Application Submittal Design Review Approval Grading & Foundation Permit Application Submittal Engineering Permit Application Submittal (Utilities & Frontage Improvements) 1B1101iff Permit Application Suk mittai'VM `t Grading & Foundation Permit Issuance Engineering Permit Issuance (Utilities & Frontage Improvements) Commence Grading, Foundation & Engineering Work Building Permit Issuance Commence Building Construction Construction Completion / Issuance of Certificate of Occupancy 9/1/2013 11/30/2013 12/1/2013 12/1/2013 T/1/2014 3/1/2014 3/1/2014 3/15/2014 5/1/2014 6/1/2014 7/31/2015 Grading & Foundation Permit Application Submittal 10/1/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 7 I 0 1 2013 fcGrading & Foundation Permit Issuance s l . iL' 1/1/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) U 1/1/2014 Commence Grading, Foundation & Engineering Work 1/15/2014 Design Review Application Submittal 6/1/2014 Design Review Approval 8/31/2014 B Iu Idmgt'Permlt Ap Iltatfon;'SuE'mlttalr U/1/20 4-;.` Building Permit Issuance 2/1/2015 ...- Commence Building Construction 3/1/2015 Construction Completion / Issuance of Certificate of Occupancy 2/28/2016 / / -3/Fogy / ! zg(44/ 3a01 7-T tar umm.

September 17, 2013 Moira Carr Bradshaw Senior Planner City of Tukwila / Department of Community Development 6300 Southcenter Boulevard Tukwila, WA 98188 RE: TUKWILA VILLAGE PHASE ONE B.A.R. PARKING COMMENTS Moira, Please see our responses in italics below to the parking comments dated August 07, 2012. Per our previous phone conversations about parking calculations, the attached parking summary has been revised to utilize the complimentary uses parking reduction as outlined in the Tukwila Zoning Code section 18.56.070.D. In addition to the complimentary uses we've also noted a request for a 5% administrative variance for the portion of the site north of S. 144th street only. 1. Parking standard for live work Applicant proposes 1.5 per unit - Is there any experience, documentation or support for this proposed standard? City of Seattle parking standard for Live -Work units (SMC 23.54.015 Table A- see attached) is 0 spaces for 1,500 sf or less and 1 space for units 1,500 sitto 2,500 sf City of Renton parking standard for Live -Work units (RMC 04-04-080 — see attached) is a minimum and maximum of one per unit. (See also attached City of Renton staff report/recommendation for parking of Live/work units based on area of unit <2,500 sf =- 1 1 stall.) The proposed Live -Work units in Building A are 465 sf on the ground floor and 200 sf on the mezzanine level = 865 sf total. We had originally calculated the residential portion of the unit at 1 stall per unit (1 bedroom) + an additional .5 stall for the non-residential portion, however given the precedent of other local jurisdictions with live -work parking quantity based on overall unit size, we propose reducing our parking to one stall per unit. See revised parking calculations attached. 2. Assumption on usable floor area Parking requirement is based upon definition of "Usable Floor area" which means that part of the floor area of any structure which is actually used from time to time for any commercial purposes, such as a sales area, display area, walkways or storage area. 15200 52nd Avenue South, Suite 300, Seattle, Washington 98188 Phone 206.766.8300 www.johnsonbraund.com ARCHITECTURE INTERIOR DESIGN Page 2 September 17, 2011 Parking calculation shall not include: • common corridors designed for the circulation of people at nonretail establishments, • restrooms, • elevator shafts and stairwells at each floor, • mechanical equipment rooms or attic spaces and • exterior covered loading docks. (TMC 18.06.863 Usable Floor Area) Please provide support for use of the 75% as a useable floor area per the definition above. The parking calculations have been revised to reflect a higher percentage of useable area. In reviewing the area of each tenant space and the anticipated use/layout (i.e. many of the small incubator space will simply have accessible unisex restroom) it was determined that the useable areas of the incubators spaces will be approx. 85-90% useable and the restaurant areas 80-85% useable. We have utilized the higher usable area in the parking calculations: 90% for general retail uses and 85% for restaurant uses. See revised parking calculations attached 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? See attached response from Parametrix dated 8-23-2013. 4. How will impacts to parkingfrom community events be managed? Parking for community events will be managed by flexible/ shared parking between phases. After business hours (5pm) and on weekends the surface parking behind building D (19 stalls) and on the access driveway between D & E (10 stalls) will be available for r Page 3 September 17, 2011 use. The on -street parking (18 stalls) is also available for event use at all times during the day (total of 47 additional stalls). We have now planned for a mezzanine level of parking in the garage of building E. This will provide an additional 33 stalls available for overflow/flexible use for Tukwila Village as needed. When large events are planned (in evenings and/or summer -months) arrangements may also be made with Foster High School to allow for over fow;bf-site parking. 5. Please verify that housing occupants will be charged for structured parking. Have you anticipated on-site or off-site impacts" and how they wil'l_be managed? Some of the housing occupants will be charger for structured parking bed on affordability levels. The low-income senior units in buildings D & E and tl e;low-income/ affordable portion of the mixed-ir come units in Buildmgs!A & B will not be'iharged for structured parking. The market rate units in building;,& B will be charged for structured parking. All residential ants must register'to park on site (in garage or on - surface). Only a limited number ofsutface parking registrations will be available (equal to the number of surface -residential stalls, provided}, f a residential tenant's car is not registered and parr an- ite,;ij,will be towed 6. Discuss the impact of reserved parking. Which stalls will be reserved, how will they be managed andsham/ how will it affect the overall supply relative to demand The 1,1,3urface parking°stalls + 1"loading stall located immediately to the north of the Library:wzll be reservectiO4r the Lilfra,y use only. The stallslocated off of T.113. and the surface stalls located immediately south of the Building A cdfnrnercial frontage will be reserved for Building A commercial customers. Stalls in the parllnfg garage of building B for employee use will be reserved. Since the library arid commercial tenants of building A are the largest/most constant uses for the project, reserving these stalls for these uses will not adversely affect supply relative to demand. There are 18 stalls west & south of Building E that are reserved (parking easement) for the adjacent King County Housing Authority project (Riverton Terrace.) Page 4 September 17, 2011 7. Will the structured parking be assessable to office/retail/library tenants? The structured parking is to be secured with locked gates and controlled access cards. Building A garage is reserved for residential tenants only. All of residential parking for building B is provided in the garage. Building B garage also has 16 additional stalls available for employee parking (building A, B, C & library employees) and (2) car-share/flex car parking. The employee parking will also be access controlled. Building D parking garage serves all of the residential tenants as well as a percentage of the office tenants. Building E garage serves all of the residential tenants as well as the parking for the Neighborhood Police Resource Center and a percentage of the office tenants in building D. Additional parking is also available for overflow/special events parking on a separate mezzanine level with separate access. 8. Show how the phasing of the project and of the parking supply will affect parking demand. For example, if all of the calculations are accurate and supportable for Phase one, then the parking demand is 190 and yet only 150 are proposed for Phase one. My understanding is that 33 stalls on Parcel B could be made available in a temporary condition. There are issues of: • the code requirement that stipulates: The surface of any required off-street parking or loading facility shall be paved with asphalt, concrete or other similar approved material (s) and shall be graded and drained so as to dispose of all surface water, but not across sidewalks (TMC 18.56.040 (7) (a.) General Requirements. • the impact of construction of Building B and the temporary elimination of the 33 stalls. If the above points can be adequately resolved, please address any deficit from the standard of stalls. Phase one requires 190 stalls + 1 car share + 2 loading stalls. 100 of the stalls are for residential tenants and 93 are for commercial uses. Phase 1 provides 149 stalls total as follows: 1 Page 5 September 17, 2011 Parcel A/Phase 1: 85 garage stalls (for residents), 51 surface stalls and 2 loading stalls. Parcel C/Phase 1: 11 surface stalls. Until phase 3 is constructed the parking demand is short 44 stalls. 34 stalls will be made available on Parcel B in a temporary parking condition. The additional 10 required stalls can be satisfied by the available on -street parking stalls on the north side of S. 144th street. (13 total.). Disruptions to available parking on Parcel B during construction of Phase 3 can be offset by flexible shared uses with Phase 2. This includes 5 additional on - street parking on the south side of C 144th street , as well as the mezzanine parking level in the garage of Building E (33 stalls). 9. Please explain the sequence of the S 144 Street improvements and the potential availability of those on -street stalls. The construction schedule of the S 144t street improvements is contingent upon the approvals of Grant applications, however the intention is that the north half of the street improvements will be complete with Phase 1 and the south ha(f of the street improvements will be complete with Phase 2.

PLANNING . ENVIRONMENTAL SCIENCES 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? Responses First Bullet: The primary intent behind using Shopping Center (Land Use 820) is that it permits the site to be flexible in offering leases to variety of tenants without having to have the exact commercial land uses identified as long as they fall within the uses listed under shopping center. Additionally, each of the commercial uses may peak at different times of the day and ITE does not have hourly variations in parking demand data for all these potential land uses. For example, a lunch -oriented deli may peak midday, but a dry cleaners may peak first thing in the morning and in the evening, but have little parking demand in the middle of the day. This helps prevent over -building parking and unnecessarily increasing impervious surface area. Second Bullet: The peak parking demand characteristics from ITE for Low/Mid-Rise Apartments shown are based on a formula rather than a rate. The formula is P = 1.42x — 38, where P is the peak period parked vehicles, x is the number of dwelling units, and -38 spaces (or vehicles) is the y -intercept of the formula. Based on the information in ITE Parking Generation, the formula is the most appropriate means estimating parking demand (the coefficient of determination, R2 , is 0.93, which indicates good correlation with the data). Third Bullet: The community assembly space in Bldg. C is included with the Shopping Center space. Shopping Centers often include assembly/gathering space for art festivals, fashion shows, and other community gatherings. The average parking demand for the community assembly space could be estimated as approximately 25 percent of the overall parking demand for shopping center.

RESIDENTIAL USES IN CENTER DOWNTOWN ZONE: http://www.codepubl ishing.com/wa/renton/html/Renton04/Renton0404/Renton0404080.ht... 9/10/2013 Whether capital improvements or expenditures are being made or completed as expected No specific capital improvements or expenditures are associated with this proposal. Consistency with GMA, the Plan, and Countywide Planning Policies This proposal is consistent with the GMA, Comprehensive Plan, and Countywide Planning Policies. Providing the live -work unit option in the CN and R-14 zones is consistent with policies of having a mix of uses and mixed-use structures spread throughout urban areas where people can both live and work and where services can be provided in closer distance to surrounding neighborhoods. Effect on critical areas and natural resource lands There is no foreseen effect on critical areas and natural resource lands. If there are such impacts with a live -work use, an environmental evaluation would be part of a project's review. Effect on other considerations None. Staff Recommendation Staff recommends that live -work units become a new use allowed in the CN and R-14 zones with the following standards: • Non-residential spaces in the units must meet commercial building standards so the space can be used for small scale business activity over the long term and fulfill the purpose of live -work, where a service is provided. • Live -work units should not be a permitted use outright, but should instead be processed through an Administrative Conditional Use Permit so conditions can be established based on local circumstances. • For the R-14 zone, live -work units should only be allowed along arterials (principal, minor, and collector) rather than allowed throughout the residential zone. This arterial criteria would limit the areas where a small business could receive clients and deliveries without negatively impacting residences. • A design standard should be required where the non-residential/business space should create a pedestrian oriented area. • Parking requirements for live -work units should at minimum require one parking space specifically for the residential space. For units 2,500 square feet or less, this one space would be the requirement for the whole unit. For units greater than 2,500 square feet, required parking would be based on the parking standards for the non-residential use or the closest similar use as determined by the Administrator. Implementation Requirements Sections in the Development Regulations (Title IV) of the Renton Municipal Code would need to be changed including: creating a definition for live -work unit, adding live -work unit to the zoning use table, and establishing requirements that live -work units only be allowed adjacent to arterials in the R-14, and that the business/non-residential spaces are pedestrian oriented along the street and sidewalk. #D-11 Page 3 of 3 March 11, 2009 iNOINEERINO . PLANNING . ENVIRONMe'NTAL .^,.CIENC' August 23, 2013 Parametrix Responses Comment 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? Responses First Bullet: The primary intent behind using Shopping Center (Land Use 820) is that it permits the site to be flexible in offering leases to variety of tenants without having to have the exact commercial land uses identified as long as they fall within the uses listed under shopping center. Additionally, each of the commercial uses may peak at different times of the day and ITE does not have hourly variations in parking demand data for all these potential land uses. For example, a lunch -oriented deli may peak midday, but a dry cleaners may peak first thing in the morning and in the evening, but have little parking demand in the middle of the day. This helps prevent over -building parking and unnecessarily increasing impervious surface area. Second Bullet: The peak parking demand characteristics from ITE for Low/Mid-Rise Apartments shown are based on a formula rather than a rate. The formula is P = 1.42x — 38, where P is the peak period parked vehicles, x is the number of dwelling units, and -38 spaces (or vehicles) is the y -intercept of the formula. Based on the information in ITE Parking Generation, the formula is the most appropriate means estimating parking demand (the coefficient of determination, R2 , is 0.93, which indicates good correlation with the data). Third Bullet: The community assembly space in Bldg. C is included with the Shopping Center space. Shopping Centers often include assembly/gathering space for art festivals, fashion shows, and other community gatherings. The average parking demand for the community assembly space could be estimated as approximately 25 percent of the overall parking demand for shopping center. To: Bryan Park From: Moira Carr Bradshaw Date: 7 August 2013 Subject: Tukwila Village Parking In order to complete the review on the parking decision for the project, the following information is needed. I will be back in the office on Wednesday August 14, 2013 and be available to go over any questions that you might have regarding the questions. 1. Parking standard for live work Applicant proposes 1.5 per unit - Is there any experience, documentation or support for this proposed standard? 2. Assumption on usable floor area Parking requirement is based upon definition of "Usable Floor area" which means that part of the floor area of any structure which is actually used from time to time for any commercial purposes, such as a sales area, display area, walkways or storage area. Parking calculation shall not include: • common corridors designed for the circulation of people at nonretail establishments, • restrooms, • elevator shafts and stairwells at each floor, • mechanical equipment rooms or attic spaces and • exterior covered loading docks. (TMC 18.06.863 Usable Floor Area) Please provide support for use of the 75% as a useable floor area per the definition above. 3. The Parking Demand Generation section of the Traffic Impact analysis by Parametrix raises the following questions: • The author uses the Shopping Center (Land Use 820) category to evaluate parking demand. The average size of the centers in the data base is 545,000 square feet, which is very different from this proposal which has a total of 17,500 square feet of commercial/retail space. Please support use of that database or use a combination of more appropriate land use codes. • Why are 38 spaces subtracted from the peak demand for the family units in Bldg.? A? (page 14) • What is the parking demand for community assembly space in Bldg. C.? 4. How will impacts to parking from community events be managed? 5. Please verify that housing occupants will be charged for structured parking. Have you anticipated on-site or off-site impacts and how they will be managed? 6. Discuss the impact of reserved parking. Which stalls will be reserved, how will they be managed and show how will it affect the overall supply relative to demand. 7. Will the structured parking be assessable to office/retail/library tenants? 8. Show how the phasing of the project and of the parking supply will affect parking demand. For example, if all of the calculations are accurate and supportable for Phase one, then the parking demand is 190 and yet only 150 are proposed for Phase one. My understanding is that 33 stalls on Parcel B could be made available in a temporary condition. There are issues of: • the code requirement that stipulates: The surface of any required off-street parking or loading facility shall be paved with asphalt, concrete or other similar approved material (s) and shall be graded and drained so as to dispose of all surface water, but not across sidewalks (TMC 18.56.040 (7) (a.) General Requirements. • the impact of construction of Building B and the temporary elimination of the 33 stalls. If the above points can be adequately resolved, please address any deficit from the standard of stalls. 9. Please explain the sequence of the S 144 Street improvements and the potential availability of those on -street stalls. JOHNSON BRAUND INC. May 28, 2013 Re: Request for Administrative Variance for 10% parking reduction Site Address: Tukwila Village Per our previous meetings with planning staff, we are requesting a parking reduction for parking requirements at Tukwila Village. As discussed the requested reduction is for 10% of the non- residential uses only. See attached calculations showing each proposed use, square footage, code required parking and 10% reduction calculation. The calculations are tabulated by location: i.e. north of S. 144th street and south of 144th street. With the proposed 10% reduction, the north portion of the site would require 267 stalls. 269 stalls are provided on-site for the north portion of the project. An additional 13 on -street parking stalls are to be provided along the north side of S. 144th street, bringing the provided parking on the north portion of the project to 282 stalls. The combined total of on-site & on -street parking exceeds the full code required parking of 277. The proposed south portion of the project has a total of 158 parking stalls provided on-site and an additional 5 stalls on -street. The code required parking (without reduction) is 150 stalls. A reduction in parking requirements is not required for the south portion of the site. The surface parking for the south portion of the site serves office uses which will have limited (work day) hours. This parking will be available in the evenings and on weekends to supplement the potential parking demand for the Library and the Community Commons. See attached for the Traffic Impact Analysis prepared by Parametrix. Table 8 and 9 estimates the parking demand for the project and concurs that the proposed parking for the project will meet the demand. Please contact me if you have any questions or comments.

Should be no problem. Those appear to be pretty easy answers to give to you. Robin From: Moira Bradshaw Sent: Monday, September 30, 2013 10:19 AM To: Robin Tischmak Cc: Minnie Dhaliwal Subject: S. 144 Street Frontage improvements Robin — Attached is a response from Tukwila Village Development regarding their parking variance request. In number 8 of their response, they state that construction of the on -street parking being shown on S. 144 Street, is contingent upon receipt of a TIB grant.

From: Minnie Dhaliwal Sent: Thursday, February 02, 2012 1:59 PM To: Jack Pace Cc: Nora Gierloff; Moira Bradshaw; Derek Speck Subject: Tukwila Village parking Jack, Based on my review of the parking calculations that you received from Johnson Braund here are my comments: 1. Overall the numbers are pretty close and it may be premature to lock ourselves into how many parking stalls are required as the site plan will evolve as the project moves forward. The code allows complementary parking where up to 10% if the usable floor area may be occupied by a complementary use without providing parking spaces in addition to the principal use (TMC 18.56.070D). I think this is what Johnson Braund is referencing in the second column, where they have reduced the parking ratio by 10% ,instead of reducing the overall floor area by 10%. Also, the code allows administrative variance for up to 10% parking reduction (TMC 18.56.140), which is referenced in the third column. One of the criteria for this reduction is that the site is at least 300 feet away from a single family zone. 2. The parking calculation for residential units is correct and it meets all the requirements including the one that requires 75% to be in an enclosed structure. There is one category called out as "residential non -senior LW". I am assuming it is live -work. The table shows 4 such units and one parking space for them. Since it is such a small component of the overall site plan that I am not sure it is of much concern at this time. Also, the code requires two additional spaces for car sharing program that are not included. 3. The parkinig calculations for the different commercial uses are correct except that a coffee shop is considered fast food (disposable containers) under our code, which requires 1 space for 50 sq. ft. So for 998 sq. ft. coffee shop thejcode requires 20 parking stalls and the table shows 5. I think a case could be made that not all users are going to drive therefore complementary parking waiver could apply. Even if we required 20 stalls the total required parking will not exceed 10% parking reduction. 4. The figure 18-7 in the zoning code states that the parking requirements for a library are to be determined by Planning Commission. However there is no process or criteria. I could include this lin the Housekeeping Code Amendments to make it Type 2 Director's approval or specify that it will be Type 4 PC approval. I will need dirJection on this issue no later than the first part of next week. The table shows 40 parking stalls for 10,000 square feet library and I am assuming that came from what the library wants not what it needs. 5. Oierall their analysis shows 281 are required by code and their target is 276. Assuming we kept the library pa king at 40 and changed the parking for coffee shop from 5 to 20 and required a couple more for residential - the total would be 298, with 10% reduction the total required would be 269 and they are targeting for 276. Therefore I don't think parking is an issue. Johnson Braund understands the parking requirements and I sure hope we will be flexible where code allows us to be. Minnie 1 Minnie Dhaliwal From: Sent: To: Subject: Minnie Dhaliwal Wednesday, August 07, 2013 3:42 PM Moira Bradshaw FW: Tukwila Village comments These were our initial comments and I think the understanding at the time was that parking was going to be addressed as part of development agreement. From: Minnie Dhaliwal Sent: Friday, March 16, 2012 3:08 PM To: Derek Speck Cc: Moira Bradshaw; Jack Pace; Nora Gierloff; Bob Benedicto Subject: Tukwila Village comments Derek, This is to follow up on our meeting yesterday. Listed below are comments from Planning and Building: Planning Comments: 1. It may be helpful to label the buildings with numbers or names eg. 1-5 2. There was discussion about required setbacks and modulation to break up the building mass and soften the facades along the east property line for building 2 (phasel). There is a 20 foot required setback for the 2"d floor and above. The current site plan does not appear to meet the standard setbacks, so this item will need to be addressed as part of the development agreement. The city could let the covered porches extend into the required setback and let the setback standard be averaged along the facades as long as the design intent of breaking up the mass are met . The city stated that 1/3 of the building length could be allowed 20 foot setback if 213rd of the building was setback 30 feet. It was decided that it is not feasible to have 1/3 or 2/3 proportions set at this time. Joe had previously stated that they could look into adding another story to modulate the upper floors and add some terraces. This is acceptable method of modulating the upper floors, however it is hard to agree on the design based on just the site plan. It was agreed that the developer's team would propose some language for the agreement to address this issue. 3. The driveway entrance to the garage along S 144th Street was discussed. Staff proposed eliminating the entrance and instead wrapping that portion of the building with residential units, similar to what the developer has proposed along a portion of the west facade. There may be opportunity to extend on -street parking in this area if the driveway is eliminated. Joe was agreeable on this issue and wanted to discuss it further with the developer and his team. 4. There was discussion about required setbacks, building massing and possibility of breaking up one Targe plaza into two/three smaller plazas for building 3 (phase2). Plazas facing east could take advantage of territorial views and plazas facing north could overlook the Village Green, but may not get as much sunshine. One option was to make the building mass "H" by sliding a portion of the building west. Fire raised an issue about ladder access to the top of the building. It was decided that fire access will be calculated to determine how much the building could be pushed back. The second floor for a portion of this building is setback 15 feet and does not meet the required setback. Joe asked for a relief from the setback along the NE corner of the building in exchange for larger setback in another area. This item will need to be addressed as part of the development agreement. Applicant to propose some language. 1 5. The pedestrian circulation arc . Phase 2 was discussed and it was decidh . needed more work. The details of the location and design of paths could be addressed as part of the design review process. It was clarified that the underground garage extended under the surface parking lot of phase 2 and the garage wall may pose some limitations on the location of landscaping. 6. It was clarified by staff that the 10% parking reduction for shared parking does not apply to the residential uses, therefore if the developer desires some flexibility in the parking standards it should be addressed in the development agreement. Since an administrative decision will be required for the library parking, staff suggested that the development agreement could include language stating that the developer will generally comply with parking regulations but the Director of Community Development is authorized to grant up to 10% par mg re•uctio 7. The site plan as proposed does not meet interior parking lot landscaping requirements and does not show landscaping along the south side S. 144TH St. If the developer seeks any relief from landscaping standards they should be addressed in the development agreement. 8. Major and minor modification of the site plan should be defined and process for reviewing and approving these modifications should be addressed in the development agreement. 9. Both driveways along TIB are right in/right out, which may impact the viability of retail. Southbound traffic on TIB will need to enter the site from S. 144th St. The access easement along the north property line was discussed. Also, opportunity to make a U-turn at TIB/144th intersection was discussed. It was decided that the developer's traffic engineer should look into opportunity to allow left turns along the northern driveway along TIB. 10. The development agreement includes a schedule and has completion dates, however the obligations of different parties should be clarified. 11. Although we did not discuss this but there are open space requirements for residential units. 100 sf/unit for senior housing and 200sf/unit for non -senior. The developer should be made aware of this requirement so they can make sure they are not going to run into any issues with this standard. Building Comments: 1. the development agreement — Under entitlements and Vesting — should include language that states that the developer is vested to the codes and ordinances in effect at the time that the permit application is deemed complete, provided that the permit application remains valid and is not expired by limitation. 2. Joe questioned whether the State provisions for five story Type VA construction would apply to Tukwila Village or the local ordinance. Ans: The local ordinance for Five story Type VA construction is more restrictive and therefore would supersede the State version of five story Type VA construction. 3. Joe questioned whether or not he could have both five story and four story Type VA construction in the same building for the purpose of not having to apply the five story requirements to the four story portion. Ans: Yes, but there needs to be definitive area breakup for the transition of applicable requirements. All five story areas must be in one block and all four story areas in another block of apartments. 4. For the purpose of vertical modulation both Bryan and Joe talked about potential six story portions of the East Building. I did not comment on this, but I do want to point out at this time, that would eliminate this building from the five story Type VA construction provisions and make them eligible for the Fire Department's Mid Rise Ordinance and all that entails. 2 Moira Bradshaw From: Diana Keys <dianak@johnsonbraund.com> Sent: Wednesday, July 24, 2013 6:10 PM To: Moira Bradshaw; Bryan Park (BryanP@housing4seniors.com) Cc: Melvin Easter; ChrisP Subject: RE: Parking for Tukwila village Attachments: LA1113 - P1.O_Overall Site Pian-redline.pdf Moira, I will respond to your parking count questions, see my responses in italics below.

The project description submitted for the TV said that there are 70 stalls in the garage of Bldg E. while Sheet P1.0 in the Johnson Braund Drawings say 80. If you could verify which is the accurate number. There are 80 stalls in building E garage. 2. I counted 81 surface stalls plus 2 loading stalls on Parcel A and C versus 93 , which is the total listed on Sheet P1.0. Where are those 10 other stalls? Per the CS summary and site plan graphics, there are 51 surface stalls + 2 loadin s stalls on parcel A nd 11 surface stalls on parcel C for a total of 64 surface stalls for phase 1. This count is consistent with the site plan graphics on P1.0, however there is a typo on the parking stall text for Parcel A surface parking — the total tally is correct. See attached pdf. 3. The 18 stalls in the southeast corner are on an easement for the King County Housing Authority, so they won't be included in the calculations for the project unless you have arranged for a shared use? We have not included the KCHA parking stalls in our counts to satisfy our required parking. Thanks for your help with my math.

Pass -by trips are trips to/from sites where the vehicle was already on the street and as it is passing by the site, the driver turns into the site to make a stop before resuming their original trip. New trips are the remaining trips, where the primary purpose of the vehicle trip was to travel to and from the site. Only the 17,210 SF of retail uses are expected to attract pass -by trips. The pass -by trip reductions applied to the retails uses were as follows: • 65 percent for the PM peak hour (based on the regression equation found for Shopping Center in the ITE Trip Generation Handbook), • 55 percent for daily (although no data exists, it has been assumed to be somewhat less than during the peak hours), and • 65 percent for the AM peak hour (although no data exists, it has been assumed to mirror the PM peak hour trend). The regression equation was used rather than the average pass -by percentage because the pass -by data for shopping centers indicate that the pass -by rate exponentially increases as the square footage of the retail decreases. This presumably occurs because larger shopping centers are more of a regional destination rather than a local neighborhood center, where someone might drop by on the way home in the evening or to the office in the Tukwila Village Development Associates LLC 554-6892-001 Traffic Impact Analysis 7 May 28, 2013 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) morning (i.e., a pass -by trip).

The new project trip distribution is shown on Figure 4. New trips are estimated to travel to/from the site in the following pattern: • 25 percent to/from the north on TIB towards Seattle. • 25 percent to/from the west on S 144th Street towards nearby neighborhoods and Military Road S. • 25 percent to/from the east on S 144th Street towards nearby neighborhoods. • 25 percent to/from the south on TIB towards the City of SeaTac and State Route 518. Pass -by traffic to/from Tukwila Village is shown on Figure 5 and was assigned based on where the uses were located on the site as well as the volume being carried in the future baseline 2015 traffic streams on TIB and S 144th Street, which indicated the following distribution for the Phase 1 pass -by trips, which are likely to arrive from both TIB and S 144th Street: Tukwila Village Development Associates LLC 554-6892-001 Traffic Impact Analysis 9 May 28, 2013 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) • 43 percent from southbound TIB • 26 percent from northbound TIB • 17 percent from westbound S 144th Street • 14 percent from eastbound S 144th Street For Phase 2 pass -by trips, the uses are set -back from TIB and much more likely to draw traffic only from S 144th Street. Given that, the Phase 2 pass -by trafficwas distributed as follows: • 54 percent from westbound S 144th Street • 46 percent from eastbound S 144th Street Lastly, because the project site provides non -motorized system improvements in project vicinity, crosswalk volumes were projected to increase by 50 pedestrians per hour with the completion of the project. For comparison, 50 pedestrians per hour represents the difference between the values suggested for assuming the number of pedestrians per hour in a rural area (zero pedestrians per hour) and a suburban area (50 pedestrians per hour). These values were documented in in the National Cooperative Highway Research Program (NCHRP) Report 599 — Default Values for Level of Service and Highway Capacity Analyses. The thought being the relative difference reflects the change from an undeveloped condition to a suburban development condition.

The proposed site uses were matched as close as possible to the data available. The parking demand estimates were compared to the proposed parking supply. A total of 427 parking stalls would be provided on-site of which 300 would be in - building (garages) and 127 spaces would be surface parking stalls. Additionally, 18 on -street parking spaces would also be provided. Table 8 below summarizes the anticipated parking demand for a typical weekday. Table 8.

Table 9 illustrates this by summarizing the parking demand as it varies throughout the day using data from ITE.

Therefore, the assumed daily distribution for family apartment units was used. 3 For the retail uses, the daily distribution of parking demand for Shopping Center (ITE Land Use 820) for a non -Friday, non - December weekday was used. 4 Used data for Library (ITE Land Use 590). 5 Used data for Office Building (ITE Land Use 701). 6 Used data for Government Office Building (ITE Land Use 730), which provides data for the time period from 9:00 AM to 4:00 PM. That was supplemented with data from Office Building (ITE Land Use 701) for the hours from 7:00 AM to 9:00 AM and 4:00 PM to 7:00 PM. Note that the above parking demand estimates have not been adjusted for the mixed-use nature of the site and the internal capture between uses, which would reduce the peak parking demand. The daily trip generation would Tukwila Village Development Associates LLC 554-6892-001 Traffic Impact Analysis 15 May 28, 2013 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) experience a trip generation reduction of 10 percent due to internal capture and a similar reduction would likely occur for the peak parking demand. One other factor that may reduce the overall parking demand is the close proximity to King County Metro bus stops on Tukwila International Boulevard and S 144th Street in the site vicinity (see the Transportation System Conditions section for detailed information about the routes and stop locations). With the overall site peak parking demand peaking at 270 parking spaces, and 427 on-site parking spaces being provided, the proposed parking supply would be adequate. TRANSPORTATION SYSTEM CONDITIONS Street Descriptions The street characteristics in the project vicinity along the project frontage are described in Table 10. Table 10. Existing Street Characteristics in Proje-Vicinity Street Name Functional Classification Tukwila International Boulevard Principal S 144th Street Collector Posted Speed Limit 40 mph 25 mph Travel Lanes Two through lanes in each direction with left -turn lanes and right -turn pockets at S 144th Street.

Signalized crosswalks are provided at the east and west legs of the TIB/S 144th Street intersection. An unsignalized mid -block crosswalk with overhead flashing beacons is also provided north of S 144th Street across TIB. Transit Service Options Bus stops for King County Metro Route 124 are located on the east side of TIB north of S 144th Street and on the west side of TIB south of S 144th Street. Metro Route 124 operates on 30 -minute headways on weekdays and connects to both SeaTac and downtown Seattle. West of TIB, there are sidewalks and bike lanes on both sides. East of TIB, there is continuous sidewalk along the north side and intermittent sidewalk along the south side. There are no bike lanes currently along either side. Signalized crosswalks are provided at the north and south legs of the TIB/S 144th Street intersection. An unsignalized crosswalk is also provided at the east leg of the S 144th Street/41st Avenue S intersection. Bus stops for King County Metro Route 128 are located on the north side of S 144th Street east of 42nd Avenue S and on the south side of S 144th Street west of TIB. Metro Route 128 operates on 30 -minute headways on weekdays and connects Tukwila to West Seattle. Crash History The five-year history of vehicle crashes in the project vicinity was reviewed to see if the crash rate appeared to be unusually high. None of the locations studied experienced crash rates in excess of 1.0 crash per million entering vehicle. In other words, the crash rates were less than one in million. Additionally, no crashes were severe enough to cause fatalities. Table 11 summarizes the five-year crash history.

The quality of traffic operations at intersections was ranked with a level of service (LOS) on an alphabetic scale from LOS A to LOS F, with LOS A being the best operations and LOS F being the worst operations. This is consistent with the Highway Capacity Manual published by the Transportation Research Board. The deterministic software, Synchro version 7 (Build 773, Revision 8), developed by Trafficware, was used to study the intersection operations. Using the intersection traffic volumes shown on Figures 2, 3, and 6, the LOS results were obtained and are summarized in Table 13 below. Table 13. Intersection Level of Service Conditions Existing 2012 Future 2015 Baseline Future 2015 with Project Intersection LOS Delay LOS Delay LOS Delay Tukwila International Boulevard at C 35.0 D 35.9 D 38.9 S 144th Street S 144`" Street at 41st Avenue S/East Drive Northbound Approach B 13.1 B Southbound Approach B 12.1 B 13.3 12.3 C 23.5 C 23.9 Tukwila International Boulevard at at North Drive (Westbound Approach) A 8.9 Tukwila International Boulevard at at Main Drive (VVestbound Approach) A 9.0 S 144`" Street at South Drive (Northbound Approach) C 20.1 None of the intersections operate worse than LOS D. With Tukwila Village, the intersection LOS would degrade from LOS B to LOS C, however, LOS C is still an acceptable LOS. As identified in the City of Tukwila Comprehensive Plan, the LOS standard is LOS D in residential areas and LOS E in commercial areas. Therefore, all of the study intersections would meet the LOS standard and no specific mitigation is recommended to improve the LOS condition at the study intersections. Driveway Channelization The proposed driveways operate at acceptable LOS with the channelization shown on the site plan. The Tukwila Infrastructure Design and Construction Standards do not contain specific channelization guidelines to follow for evaluating channelization proposed at driveways beyond LOS conditions, but do mention the City recognizes and uses the most current edition ofA Policy on Geometric Design of Highways and Streets by the American Association of State Highway and Transportation Officials (AASHTO) for channelization guidelines. AASHTO does not have quantitative guidelines for recommending right -turn channelization and the City's standards indicate that the City recognizes the WSDOT Design Manual as a reference, which does have quantitative guidelines for right -turn channelization, therefore, that has been used to supplement the AASHTO reference. The greatest potential need for left -turn channelization on a public street to serve movements into the project site would occur at the S 144th Street/East Drive/41 st Avenue S intersection. In reviewing the AASHTO guidelines and extrapolating for a 30 -mph operating speed,,the combination of left -turn volumes, advancing and opposing volumes at the East Drive intersection do not warrant the a left -turn lane. The greatest potential need for right -turn channelization on a public street to serve movements into the project would occur at the TIB/Main Drive intersection. At this intersection, 62 vehicles would turn into the Main Drive with 528 vehicles traveling advancing northbound behind them. However, there are two northbound travel lanes and the posted speed limit is 40 mph there. The WSDOT Design Manual only recommends using the Design Tukwila Village Development Associates LLC 554-6892-001 Traffic Impact Analysis 18 May 28, 2013 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) Manual Exhibit 1310-19 in developing recommendations for right -turn lanes when multilane facilities have posted speed limits of 45 mph or greater. Additionally, given that King County Metro has a bus pull-out in close proximity that would conflict with a right -turn lane, no right -turn lane is recommended on TIB at the Main Drive. Driveway Sight Distances The sight distance exhibits prepared by Barghausen Consulting Engineers indicate that the proposed driveway locations would have adequate sight distance per City standards. Therefore, no sight distance improvements are recommended. It is recommended that sight distance triangles be regularly maintained. Driveway Access Spacing & Corner Clearances The proposed driveways were located based on site constraints and access spacing and corner clearance guidelines. The City Engineer has reviewed preliminary plans and found the location of the proposed driveways to be acceptable. MITIGATION FEE REQUIREMENTS Mitigation fees are due to the City at the time of building permit issuance to pay for the project's proportionate share of impacts. Additionally, the proposed development must pass the concurrency test conducted by the City of Tukwila. CONCLUSIONS & RECOMMENDATIONS The proposed Tukwila Village would not create significant adverse impact on the transportation system. The primary recommendations are: • Maintain clear sight triangles • Pay for the project's proportionate share impacts via the City's traffic impact fee program Tukwila Village Development Associates LLC 554-6892-001 Traffic Impact Analysis 19 May 28, 2013 Attachment A Trip Generation t` TripGen & Volumes 2013-05-20.xlsx per td E m g 2 N 8' ^ i N8�OERE F 3 EgE2 , �°(IOEii Ei fi ^ N tE O F Z N 2 n m R t') F NNP 2 A A B E E F 4, f N R N E o v^ ' gg 2� 1p N ^ 1 2ERF O� CA FHA iE$ g F g 1P0 E O 0 O O O 0 0 0 0 0 0.0 O O O 0 0 0 0 0 0 0 0 0 0 6 a o 0 0 0 0 0000.. 0 0 0 0 0 0 0 0 00 H 0 0 0 0 0 0 000000 0 0 000000 0000 {I00 Eu" g 0 0 0 ----Zr 0 0 ,t. lh,,mN 0 0 0 al 0p'02 URNS 0 0 0 0 a om00 O 0 0p'og SSg� m fo -o 0 0 0 0 E20p00 0 0 00000^ IRE EL g e E g U€ N� f6 '' iE N .O- ^ T � E Omi � N t09 6 0 � m b 0^ v � �i N N N'l ' �6 o ' 1� e -Y 2 �_ 5 2 a wNo m '°9N'w 0 3g� E ;;NN^ "m m % o .R r of Q R N n SAFF2' N F.'E6Raa� 'HER �) Tri Gene internal pipe $ 131 ggi g 3 5 22 R ^ ' me^i:'-'w2 m n 71 &4 m.-n4L6,4 s- W 2 2 m 2 0N::^;N m N N &S744d 222q 30 F 0 N P. 2 2 2 N '422.0224 m 0 § 4V2VY.'
