l93-0087 4060 south 144th street foster library SEPA REVIEW ENVIRONMENTAL IMPACT STATEMENT (EIS) FOSTER LIBRARY TUKWILA, WASHINGTON LEVEL 1 DOWNSTREAM DRAINAGE ANALYSIS NOVEMBER 1993 Barrett Consulting Group 10800 N.E. 8th Street, 7th Floor Bellevue, WA 98004 (206) 455 -9494 Prepared by DEC '' 1993 David E. Dorothy, P.E. Project Manager LEVEL 1 DOWNSTREAM DRAINAGE ANALYSIS FOR FOSTER LIBRARY An offsite downstream drainage analysis was performed in accordance with the City of Tukwila requirements and the King County Surface Water Design Manual dated January 1990. The site investigation was performed on November 10, 1993. The 1.15 -acre site is located at the northwest corner of the intersection of S. 144th Street and 42nd Avenue S. It is within the drainage basin tributary to Gilliam Creek southeast of the site. Areas north of the site, including Foster High School, drain north into the Fostoria Drainage Basin. For approximately one - quarter mile, the drainage system downstream of the site consists of a pipe conveyance system ranging in size from 12- to 24 -inch CMP (see Exhibit A, attached). The existing system in S. 144th Street adjacent to the site drains east to 42nd Avenue S., then south along the east side of 42nd Avenue S. through a series of catch basins and 12 -inch CMP, until S. 146th Street where the pipe increases to 18 -inch. At the southwest corner of 42nd Avenue S. and S. 146th Street, the 18 -inch pipe crosses to the west side of 42nd Avenue S., and then continues south. The 18 -inch pipe enters a manhole approximately 100 feet south of S. 148th Street. This manhole also picks up flow from a ravine to the northwest via a 24 -inch pipe. A 24 -inch pipe exits the manhole to the southeast across 42nd Avenue S. It appears to cross private property and discharge into an existing ravine /creek to the southeast. The creek is on private property and was not walked. The aerial mapping from the City shows that the creek continues southeast to S. 150th Street. At S. 150th Street, the creek enters a 36 -inch concrete culvert under the road. The inlet and outlet ends of the culvert were heavily rocked. This point was approximately 2,300 1.f. (0.44 miles) downstream of the site. The investigation was terminated at S. 150th Street. In summary, there was no evidence of overtopping, flooding, erosion, or restrictions in that portion of the downstream conveyance system that was investigated. Based on visual evidence, the development of the Foster Library site should not have a significant impact on the existing drainage system for at least one - quarter mile downstream from the site, provided that the City of Tukwila drainage standards are incorporated into development of the site. 1250101.002 1 Roadway and drainage improvements for 42nd Avenue S. from S. 154th Street to S. 144th Street are tentatively scheduled for construction in 1994. Those improvement plans are being prepared for the City by Perteet Engineering, Inc. Attached is a copy of a letter from Kevin Weed (Perteet) to Ross Heller (City) summarizing the proposed stormwater system for the entire roadway project. Kevin Weed was contacted about the proposed Foster Library project and said the storm drainage improvements for 42nd Avenue S. will have sufficient capacity to handle the additional flow from the project, provided standard onsite detention is incorporated in accordance with the City of Tukwila drainage standards. 1250101.002 8,3.0 282.5 X lJ 77.0 Paved 2840 S.

This section of roadway lies within the Gilliam Creek Basin and discharges into an existing depression (Regional Pond #2) on the north side of South 154th Street just east of the subject project. We recommend that the storm water runoff along this section of roadway be handled as follows: • To reduce erosion in the upper channel from South 148th Street to Regional Pond #2, the runoff will be split through a control structure. Low flows will be released into the channel while high flows will be carried within the storm drain system to South 152nd Street. • Water quality will be provided with the use of a grass lined swale at the vicinity of South 152nd Street. Construction of this swale will require the acquisition of right - of -way from the parcel just to the north of the unopened right -of -way for South 152nd Street on the east side of 42nd Avenue South. Low flows will be carried through the swale. • Discharge of high flows at South 152nd Street will be through a tight line storm drain that runs along the unopened right -of -way and outfalls directly into Regional Pond #2. If you have any comments or need additional information please do not hesitate to give me a call. Sincerely, PERTEET ENGINEERING, IN Zest Kevin E. Weed, P.E. Project Manager ... EXECUTIVE SUMMARY INTRODUCTION The 42nd Avenue South roadway improvements construction project extends from South 139th Street to South 154th Street. The northerly portion between South 139th and South 144th Street lies in the Fostoria Drainage Basin, while the southerly portion between South 144th and South 154th Street lies in the Gilliam Creek Drainage Basin. The combined catchment for the entire Gilliam Creek Drainage Basin converges at an existing depression on the north side of South 154th Street just east of 42nd Avenue South. Outfall from this depression is via an existing 30 -inch diameter pipe which extends to the east approximately 0.3 mile. The purpose of this summary is to define and address the needs for storm water facilities to mitigate erosion northwest of the depression, provide water quality enhancement for the 42nd Avenue pavement runoff and construct detention for the increased impervious surfaces due to the 42nd Avenue street improvements within the Gilliam Creek Drainage Basin. PROCESS Review the existing storm conditions at the existing depression and determine what the conditions will be following the widening of 42nd Avenue South. This process involves a hydrograph analysis of the runoff for the existing and developed 2, 10, 25, and 100 year storm events. The volume of water detained in the depression during the various storm events was computed and compared for both existing and developed conditions. EXISTING CONDITIONS During the 100 year storm event the water depth in the depression is approximately 47 feet. The outfall elevation for the depression is 145.0 and the maximum pond elevation is 192.39 feet. This increase in water elevation does raise some concerns by the local residents and City staff. PROPOSED IMPROVEMENTS Phase 1 improvements include roadway widening from South 154th Street to South 139th Street. The drainage area from South 144th Street north will include an in -line storm water detention pipe at the vicinity of South 139th Street, this runoff will outfall into Southgate Creek. The section from South 144th Street to South 154th Street will outfall into Gilliam Creek. The proposed widening from South 144th Street to South 154th Street will discharge at three locations, vicinity of South 148th Street, South 152nd Street and the existing 42nd Avenue South Page 1 Stormwater Runoff S. 152nd to S. 144th Street Executive Summary outfall where 42nd Avenue crosses Gilliam Creek near SR 518. The increase in impervious area along this section of roadway is 1.01 acres. This increase in impervious area will cause the elevation of water in the depression to increase by less than .1 % during the major storm events, approximately 0.03 feet. At South 148th Street, a control structure will be provided to split the runoff. Low storm events will be routed directly into the existing channel between South 148th Street and the existing depression and the higher storm events will by -pass the existing channel and outfall along South 152nd unopened right -of -way into Gilliam Creek at the depression. This will reduce the current rate of erosion occurring upstream from the depression to the north. Subtracting the difference between the existing and developed 25 year storm events, a volume of 5100 cubic feet is determined. This is the volume of detention required for the additional impervious surfaces constructed with this project. This would require an in -line detention pipe that is 200 feet long and six feet in diameter. In -order for this the in -line detention to be effective, a flow splitter will need to be constructed to divert low flows (magnitude of runoff from the roadway only), to the detention pipe while bypassing the remaining flows directly into the depression. Diversion of low flows can also be accomplished to the biofiltration swale for water quality enhancement. Water quality treatment along a grass line swale would require the acquisition of property from Mr. Richard Holley just to the north of the unopened right -of -way. The required swale length is 300 feet and the bottom width is 8 feet. Low flows would go through the swale, while high flows would be bypass the swale along a tight line storm drain the discharges directly into the depression. RECOMMENDATIONS It is desirable to construct the flow splitter at South 148th Street to divert high flows away from the existing channel and into a pipe by -pass system. We recommend construction of the splitter to reduce the erosion within the existing channel. We further recommend construction of the biofiltration swale prior to the outfall at South 152nd Street. This will provide the desired water quality enhancement for the 42nd Avenue roadway improvements. In -line detention near South 152nd Street may be cost prohibitive. This section of roadway is already inundated with underground utilities and providing for in -line detention as well as a flow bypass would require relocating of either the high - pressure gas line, water line, or storm sewer line. Because of this we would recommend tight lining the runoff directly into the depression with the exception of the low flows that will be routed through a grass lined swale. This proposal will not have an adverse impact on the water levels within the depression during major storm events. Overall this proposal will reduce the impact on stream erosion and provide some water quality treatment. 42nd Avenue South Page 2 Stormwater Runoff S. 152nd to S. 144th Street Executive Summary Geotechnical Report Proposed Foster Library Tukwila, Washington September 29, 1992 Prepared for King County Library System Seattle, WA Prepared by Landau Associates, Inc.

EXECUTIVE SUMMARY The following presents a summary of the principal findings and recommendations related to geotechnical design of the proposed Foster Library site. The full report, as follows, should be consulted for further details on each point as well as complete description of all findings. • The site is covered with about 1 to 3 -h /2 ft of sandy silt underlain by Vashon- age glacial till composed of varying amounts of silt, gravel, and sand. The glacial till is dense in the weathered zone and dense to very dense when unweathered. The organic topsoil layer is expected to be typically less than 1/2 ft thick. • Site preparation for development of the site is anticipated to be similar to most other sites in the Puget sound area. It will be necessary to strip the surficial sod and topsoil from the building and paved areas to a depth of about 6 inches. The site soils are sensitive to moisture and difficult to compact unless the moisture content at the time of compaction is near optimum. Use of the onsite soil for grading and placement as compacted fill should be limited to summer and early fall months. If site grading is performed during wet weather, it may be necessary to use an imported, clean, well- graded sand or sand gravel for use as structural fill. • The soils present are suitable for support of conventional, shallow spread - footing foundations. Net allowable bearing pressures on structural fill or proof -rolled undisturbed stiff to very stiff sandy silt and medium dense weathered glacial till are 3,000 psf; allowable bearing pressures on undisturbed dense to very dense unweathered glacial till are 6,000 psf. • Properly prepared soil on the site is suitable as subgrade for anticipated asphalt pavement sections. 09/29/92 WBRARY\FO6TER2.RFT 11 LANDAU ASSOCIATES, INC.

INTRODUCTION This report presents the results of our explorations and analyses, and provides geotechnical engineering design recommendations for the proposed Foster Library. The library site is located at the northwest corner of the intersection of S. 144th Street and 42nd Avenue S. in the City of Tukwila, Washington. The site location is shown on the Vicinity Map, Figure 1. This report has been prepared based on information provided in the request for proposal dated July 28, 1992, and our discussions with Mr. Douglas N. Blair of the King County Library System. The present plans for development of the 1.15 -acre site include the proposed library building and an associated parking area for about 30 cars. We understand that the location of the building within the site has not been determined at this time, but likely will be in the southeast portion. We also understand that the building will be a one -story structure, approximately 5,250 ft2 in area. Finish floor elevations are expected to be near existing grade. Structural loads were not available, but are expected to be typical for a structure of this type. SCOPE OF SERVICES The purpose of our field explorations was to determine the subsurface soil and ground water conditions at the proposed library site. Subsurface soil and ground water conditions were explored by excavation of 5 test pits. The field explorations provide a basis for our recommendations regarding site development and foundation support. Our scope of services is outlined in our proposal letter dated August 5, 1992. Authorization to proceed was provided by signed proposal on August 6, 1992. Our services consisted of • Excavating 5 test pits across the proposed library site • Logging each test pit as to thickness and depth of each soil unit recorded, and classifying the soil encountered • Limited laboratory analyses on selected soil samples • Engineering analyses in support of our conclusions and recommendations 09/29/92 LIBRARY \FOSTER2.Rl'T 1 LANDAU ASSOCIATES.

Our scope also included conducting a Phase I Environmental Site Assessment. The results of that study are submitted to King County Library System in a separate report. SITE CONDITIONS Surface Conditions The site is covered with dense, relatively tall grasses, areas of thick brush, a grove of untended fruit trees, and isolated trees. A small house occupies a portion of the site. A 4-ft square, concrete, hand -dug well shaft with concrete lid is located to the east of the house. Other miscellaneous surface features include a driveway with quarry spall rock surfacing, isolated piles of construction materials and demolition debris, an isolated concrete sidewalk, a small boat, and a small house trailer. The existing site features are approximately located on the Site Map, Figure 2. Topographically, the site slopes gradually downward in a south - southwesterly direction, with an overall elevation difference of about 7 ft across the site. A slight topographic depression is apparent in the southwest portion of the site. Geology Glacial deposition and erosion during the last period of continental glaciation, as well as post - glacial erosion processes, influences present geology and topography of the Puget Sound area. The surficial geology of the site generally consists of a thin layer of topsoil over approximately 1 to 31/2 ft of overconsolidated sandy silt soil overlying, in turn, denser, weathered and unweathered glacial till deposits. 09/29/92 LIBRARY \FOSTER2.RPT 3 LANDAU ASSOCIATES, INC. 139007.10 King County Lbrary SysterniProposed Foster Library/Geotechnlcal Roport 9/92 TP-5 IS Test Pit Location and Identification Source: Property boundaries from King County Library System Facsimile Transmission (July 28,1992) 1 Site Map I Figure 2 4 LANDAU ASSOCIATES.

However, the test pits were excavated during a relatively dry period of the year, and isolated perched groundwater conditions could occur during wet periods near the ground surface above the silt and glacial till layers. These perched water layers would produce near - surface seepage into construction excavations. Groundwater was observed and measured during examination of the existing well. The well is about 4 ft in diameter and appears to have been hand or mechanically excavated. The upper 7 ft of the well shaft is square, measuring 4-ft by 4-ft, and cased with concrete. Below the concrete, the well is round and uncased to an overall measured depth of about 26 ft. The static groundwater level in the well at the time of our field exploration was measured at a depth of about 13 ft below the top rim of the existing concrete casing. This corresponds to a groundwater level at an estimated relative elevation of approximately 93 ft (assumed datum —see Appendix A). Based on soil conditions exposed in the uncased portion of the well, it appears that the well probably intercepts a permeable soil layer, or shallow aquifer, at some point below the measured groundwater surface. Consequently, the measured groundwater level likely represents the piezometric surface of the aquifer and would be expected to fluctuate according to seasonal precipitation and other regional factors. CONCLUSIONS AND RECOMMENDATIONS General Subsurface conditions at the site are generally conducive to the planned site development. Conventional shallow column and continuous footings, floor slab -on- grade, and typical pavement sections are feasible. The unweathered till found at depth will provide excellent foundation support for the proposed building. Adequate foundation support will also be provided by proof - rolled, undisturbed, sandy silt and weathered glacial till or properly compacted structural fill. The site soils are moisture sensitive and are susceptible to softening and disturbance by construction equipment when wet. The soils will need to be near their optimum moisture content in order to achieve the proper compacted density. Consequently, site grading operations should be scheduled for dry summer and early fall months, which usually occur from late June through September. 09/29/92 LIBRARY \FOSTER2.RPf 6 LANDAU ASSOCIATES, INC. Stripping and Proof - Rolling All topsoil and organic and man -made debris must be stripped away from the area to be occupied by the proposed building and paved areas. Following building demolition, clearing, stripping, and site excavations, but prior to placement of any fill or base - course material, the exposed subgrade under all areas to be occupied by pavement, earth - supported floor slabs, and spread or continuous foundations, should be proof - rolled. Proof - rolling should be accomplished with appropriate compaction equipment, such as a large, self - propelled vibrating roller so that the upper 8 inches of subgrade is compacted to a density of at least 95 percent within building areas and 92 percent within paved areas. The percentage compaction should be as determined by the ASTM D -1557 test procedure. The purpose of proof- rolling operations is to compact the soil exposed by cutting and excavation operations, and to detect possible localized zones of soft or loose soil. Proof - rolling should be carefully observed by geotechnical personnel, and any areas exhibiting significant deflection, pumping, or weaving that cannot be readily compacted should be overexcavated and backfilled with appropriately compacted fill soil. Fill and Compaction Based on our evaluation of existing topography, and our understanding of the proposed project, it appears that after site stripping, grading of the site likely will result in limited cut and fill in building and paved areas. Structural fill used to obtain final grade elevations for footings, earth - supported floor slabs, and pavements must be properly placed and compacted. Any suitable, nonorganic, predominately granular soil may be used for fill material. The moisture - sensitive native site soil may be used for fill below slabs and within pavement areas, provided the material is properly moisture conditioned prior to placement and compaction. The native site soil is not recommended for use as structural fill beneath footings. If the existing onsite soil is to be reused for structural fill, any large cobbles or other material (greater than about 6 -inch diameter) should be removed. Excavated onsite material containing topsoil, wood, trash, or construction debris will not be suitable for reuse as structural fill and should be properly disposed offsite. The suitability of excavated site soil or imported soil for compacted structural fill will depend on the gradation and moisture content of the soil when it is placed. As the amount of fines (that portion finer than the U.S. Standard No. 200 sieve) increases, the soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. Soil containing more than about 5 percent fines cannot consistently 09/29/92 UBRARY\FOSTFR2.RPf 7 LANDAU ASSOCIATES. INC. be compacted to a dense, nonyielding condition when the water content is greater than optimum. Optimum moisture content is that moisture content which results in the greatest compacted dry density. The field moisture content of the site soils was variable. The moisture content of shallow soils would also be expected to vary seasonally. Most shallow soils within the site consist of sandy silt, with a fines content of over 50 percent; and the deeper glacial till has a fines content expected to be on the order of about 20 -30 percent, or higher. The amount of fines indicates that excavated native soils will be moisture sensitive. These materials will be suitable for use as structural fill only if placed and compacted during dry weather, when the moisture content can be maintained near optimum. Based on their present natural moisture content, the site soils could be close to, and possibly above, optimum indicating that moisture conditioning could be required. In addition, the moisture content would be expected to increase during wetter months to percentages possibly well above optimum. Therefore, we recommend use of the site soils for structural fill be limited to the summer and early fall months. If construction is accomplished during wet weather, we recommend that structural fill consist of an imported, clean, well - graded sand, or sand and gravel containing less than 5 percent passing the No. 200 sieve, based on a wet sieve analysis of that portion passing the 3i4-inch sieve. Fill should be placed in maximum 8- to 10 -inch loose lifts and thoroughly compacted. Under building areas, all structural fill should be compacted to at least 95 percent of the maximum dry density as determined by the ASTM D -1557 test method. In paved areas, the fill should be compacted to at least 92 percent, except the upper 12 inches of subgrade, which should be compacted to a minimum of 95 percent of maximum dry density. If placed prior to construction of building foundations, compacted fill should extend past the building limits a lateral distance that is at least equivalent to the fill thickness. It is important that plumbing and utility trenches be properly backfilled and compacted to minimize the possibility of localized loss of floor slab or pavement support. Backfill in trenches should meet the appropriate compaction criteria previously described. Permanent cut or fill slopes should not be steeper than 2:1 (horizontal to vertical [H:V]). All cut or fill slopes should be vegetated or otherwise protected to limit the potential for erosion. Foundation Support We recommend that the planned building be supported on isolated or continuous spread footings founded on undisturbed or recompacted native soil or compacted structural fill. Bearing 09/29/92 LIBRARY \FOSTER2.RPf 8 LANDAU ASSOCIATES, INC. • soil that is disturbed during foundation excavation should either be recompacted or removed. All soil directly below and around footings should be compacted to at least 95 percent of maximum dry density (ASTM D -1557) prior to placement of forms and reinforcing steel. All continuous and isolated spread footings should have minimum widths of 18 and 24 inches, respectively, and should be founded a minimum of 18 inches below the lowest adjacent final grade. All shallow footings supported on properly prepared native soils or structural fill may be proportioned using a net allowable bearing pressure as follows: Net Allowable Bearing Foundation Soil Type Pressure (psf) Structural Fill or Proof - Rolled Undisturbed Stiff to Very Stiff Sandy Silt Undisturbed Dense to Very Dense Glacial Till 3,000 6,000 The term "net allowable bearing pressure" refers to the pressure that can be imposed on the soil at foundation level resulting from the total of all dead plus live loads exclusive of the weight of the footing or any backfill placed above the footing. These values may be increased by one -third for transient wind or seismic loads. The higher bearing pressure for glacial till applies to the dense to very dense undisturbed material. This soil is typically gray brown with orange and rust mottling where weathered, and brown gray where unweathered, and is more difficult to excavate than the overlying soils. It was typically disclosed at depths of about 1-1/2 to 4 ft below the existing ground surface across the site. For this higher bearing pressure to apply, the footings may need to be deepened, in places, to sufficient depth to bear directly on this soil. Settlement of spread foundations depends on foundation size and bearing pressure, as well as the strength and compressibility characteristics of the underlying bearing soil. Assuming construction is accomplished as previously recommended and for the loads anticipated, we estimate the total settlement of foundations should be less than about 3/4 inch; and differential settlement between two adjacent load- bearing components supported on competent soil should be less than about 1/2 inch. Most of the settlement should take place relatively rapidly during construction as loads are applied. We recommend that footing excavations be observed by a geotechnical engineer to confirm that design conditions are met. 09/29/92 LIBRARY \FOSTFR2.RPT 9 LANDAU ASSOCIATES, INC. Floor Slab Support Preparation of the building area in a manner described in the previous sections of this report should provide an adequate base for floor slab support. We recommend that all earth - supported floor slabs be underlain by 6 inches of compacted, clean, free - draining sand and gravel to provide uniformity of support and to provide a capillary break. (Provisions should be made so that this material can drain freely to the footing drain system.) The sand and gravel should contain less than 5 percent passing the U.S. No. 200 sieve, based on a wet sieve analysis of that portion passing the No. 4 sieve. Because of the fine - grained nature of the underlying native subgrade soils, we recommend providing a vapor barrier below the floor slab. The vapor barrier, if used, should be covered with a thin layer of sand to protect it from concrete placement and to aid in concrete curing. Lateral Earth Pressures Lateral earth pressures, which develop against subsurface walls and retaining walls, will depend on the method of backfill placement, degree of compaction, backfill slope, type of backfill material, drainage provisions, and the degree to which the wall can yield laterally during or after placement of backfill. When a subsurface wall is restrained against lateral movement or tilting, the soil pressure exerted is the at -rest soil pressure. Wall restraint may develop if a rigid structural network is constructed prior to backfilling or if the wall is inherently stiff or restrained from rotation. However, if the wall is allowed to rotate or yield so the top of the wall moves an amount equal to 0.001 times its height, the soil pressure exerted will be active soil pressure. We recommend that yielding walls with level backfill be designed for an equivalent fluid density of 35 pounds per cubic foot (pcf) for the active soil conditions. Nonyielding walls should be designed for an equivalent fluid density of 55 pcf for at -rest conditions. Design of any subsurface walls should include appropriate lateral pressures caused by any adjacent surcharge loads. For uniform surcharge pressures, a uniformly distributed lateral pressure of about 0.30 and 0.45 times the surcharge pressure should be added for yielding and nonyielding walls, respectively. We have assumed that the backfill placed behind retaining walls will be free - draining granular materials. We recommend that drainage provisions be included in the design of all retaining walls. Accordingly, the lateral earth pressures previously recommended assume drained conditions behind the wall and do not include hydrostatic water pressure. 09/29/92 LIBRARY \FOSTER2RPf 10 LANDAU ASSOCIATES, INC. Lateral loads may be resisted by passive earth pressures developed against the side of the foundation. For design purposes, a passive resistance of well- compacted fill placed against the sides of the foundations may be considered equivalent to a fluid with a density of 300 pcf. This value assumes drained conditions that will prevent the buildup of hydrostatic pressure in the compacted fill. A coefficient of base friction of 0.30 may be used between the base of the footing and the underlying soils. A factor of safety of at least 1.5 is included in the passive pressure and base friction design values. Drainage We recommend that an exterior footing drain system be constructed around the perimeter of the building foundations and adjacent to any subsurface retaining walls. The drains should consist of a perforated pipe placed in clean, free- draining sand and gravel or pea gravel backfill. If sand and gravel is selected, it should contain less than 3 percent by weight passing the No. 200 sieve size based on wet sieve analysis of that portion passing the No. 4 sieve. The drainage backfill should be completely surrounded by a drainage geotextile material such as Mirafi 140N, Supac 4NP, or equivalent. The footing drain should discharge to a stormwater drain system or an approved drain outlet. The surface of the ground around the building should be properly graded to direct stormwater runoff away from the building. Roof drainage must not be introduced into the perimeter footing drain, but should be discharged away from the building. Paved Areas On the basis of our review of site soil conditions, a California Bearing Ratio (CBR) value of 10 percent has been assumed for the near - surface, stiff to very stiff, silty sand. This value is based on correlation of soil type and on experience at sites with similar soil conditions. The pavement section must be installed over firm subgrade. Proof rolling of the exposed subgrade soil and fill placement to final pavement subgrade elevation should be accomplished as previously described. Following excavation or filling to establish subgrade elevation, but immediately prior to paving, the subgrade surface should be proof rolled with a loaded 10 yd3 dump truck, heavy roller, or equivalent. Soft areas exposed by this proof rolling, which cannot be easily compacted, should be overexcavated and backfilled with compacted granular fill. We understand the paved areas of the site will be used primarily for car and light truck parking. Occasional heavier trucks may use portions of the site for deliveries. Typical 09/29/92 LIBRARY \FOSTFR2.RPf 11 LANDAU ASSOCIATES. INC. recommended pavement sections for car and light truck parking consist of a minimum of 2 inches of asphalt concrete over at least 4 inches of crushed rock base on a properly prepared subgrade. Pavement sections in driveway and truck access /loading areas should consist of a minimum of 3 inches of asphalt over a 4-inch crushed rock base. From a practical perspective, compaction of any of the moisture - sensitive soil on the site will probably only be possible during extended dry weather conditions. Construction in wet - weather conditions may not allow proper compaction of the subgrade. In this case, it may be necessary to overexcavate soft and wet surficial soil and replace it with clean, well- graded sand and gravel or base - course material. In effect, this replacement increases the overall pavement section. The thickness of the granular subbase layer depends on the condition of the soil at the time of construction, but the thickness could be on the order of 6 -12 inches. If the subgrade is particularly soft or disturbed by construction equipment during wet weather, an even thicker subbase layer or the use of a geotextile material may be appropriate to achieve suitable conditions for the pavement section. Base - course materials should be compacted to a minimum 95 percent of maximum dry density, as determined by the ASTM D -1557 test procedure. Prevention of pavement base saturation is essential for pavement durability; thus, efforts should be made to limit the amount of water entering the base course. Asphalt concrete should be Class B aggregate material conforming to Section 5 -04 of the Washington State Department of Transportation Standard Specifications for Road, Bridge, and Municipal Construction. If possible, construction equipment imposing loads greater than the loads assumed m the asphalt pavement design should not be allowed on the parking areas. During construction, however, it may be necessary to move heavy construction equipment across the parking areas. If the use of construction traffic across the paved areas cannot be avoided, a haul road or increased pavement section should be installed across a portion of the site, and construction equipment limited to that area. Design Review /Construction Monitoring We recommend that a general review of the earthwork and foundation portion of the design drawings and specifications be accomplished by a geotechnical engineer to verify that the recommendations presented in this report have been properly interpreted and implemented in the design and specifications. We recommend that geotechnical construction monitoring services be provided. Construction monitoring should include observation of fill placement /compaction 09/29/92 LIBRARY \FOSTFR2.RFT 12 LANDAU ASSOCIATES, INC. activities and proof- rolling operations to verify that design subgrade conditions are obtained beneath the building addition and paved areas. In addition, we recommend that density testing be performed on prepared foundation and floor slab subgrade, and on base course material. The purpose of these services would be to observe compliance with the design concepts, specifications, and recommendations of this report, and to allow design or construction changes in the event subsurface conditions differ from those anticipated prior to the start of construction. Landau Associates would be pleased to provide these services for you. USE OF THIS REPORT Landau Associates has prepared this report for the King County Library System and their design consultants for use in the design of the proposed Foster Library. Our services have been conducted in accordance with generally accepted practices of the geotechnical engineering profession; no other warranty, express or implied, is made as to the professional advice included in this report. There may be some variation in subsurface conditions at the site. Accordingly, a contingency for unanticipated conditions should be included in the construction budget and schedule. We should be contacted if variations in subsurface conditions are encountered. We appreciate the opportunity to provide these services and look forward to assisting you in the future.

APPENDIX A FIELD EXPLORATIONS AND LABORATORY TESTING Field Explorations Subsurface conditions at the site were explored by excavating five test pits at the locations shown on the Site Map, Figure 2. The test pits were excavated to depths ranging from 6 to 7 ft below existing site grades with a tractor - mounted backhoe. The soils encountered were described in the field using the Soil Classification System presented on Figure A -1, in general accordance with ASTM D -2488, Standard Recommended Practice for Description of Soils (Visual - Manual Procedure). Logs of the test pits are presented on Figures A -2 through A -5. The exploration logs represent our interpretation of the field logs and the results of our laboratory classification testing. The field explorations were coordinated by a geotechnical engineer from our staff who monitored exploration activities, obtained representative soil samples, described the soil by both visual and textural examination, and maintained detailed records of subsurface soil and groundwater conditions. The test pits and other site features were located in the field by pacing and hand taping from an existing storm water catch basin on S. 144th Street, near the southwest corner of the site. The ground surface elevations shown on the test pit logs were determined using a hand -held level, and should be considered approximate. The elevations reference the inlet grade of the above mentioned catch basin, which was assigned an arbitrary elevation of 100 ft. Laboratory Testing Laboratory tests were performed on representative samples of the soil encountered to evaluate pertinent physical characteristics. The laboratory program was limited to sample inspection to confirm our field soil descriptions, natural moisture content determination, and a fines content analysis. Natural moisture content determinations of the samples were performed in general accordance with ASTM D -2216 test procedures. The results from natural moisture content determinations are indicated on the test pit logs adjacent to the corresponding sample number. One soil sample was washed, in general accordance with ASTM D -1140 test procedures, on the U.S. Standard No. 200 sieve to determine the relative percentage by weight of fines (that portion finer than the U.S. Standard No. 200 sieve) contained by those soils. The sample tested was from Test Pit TP -2 (Sample 2 at a depth of 2 ft). The fines content of this sample was 63.4 percent. 09/29/92 LIBRARY \FOSTER2RPT A -1 139007.10 King County Library SystemrProposed Foster Lbrary/Geolechnical Report 9192 MAJOR DIVISIONS Soil Classification System USCS GRAPHIC LETTER SYMBOL SYMBOL(1) TYPICAL DESCRIPTIONS (2)(3) COARSE - GRAINED SOIL (More than 50% of material is larger than No.200 sieve size) GRAVEL AND GRAVELLY SOIL (More than 50% of coarse fraction retained on No.4 sieve) CLEAN GRAVEL (Little or no fines) , re- :0•• • '.. - •4 GW GP GM GC Well-graded gravel; gravel/sand mixture(s); little or no fines Poorly graded gravel; gravel/sand mixture(s); little or no fines Silty gravel; gravel/sand/silt mixture(s) Clayey gravel; gravel/sand/silt mixture(s) ".. .:9: ?• "ci *.'•.:d GRAVEL WITH FINES (Appreciable amount of fines) i 1' . 41 • is •.% • • A t• - lii01 ii.

INC. t INTRODUCTION This report presents the results of a Phase I Environmental Site Assessment performed by Landau Associates, Inc. (Landau Associates) for the property located on the northwest corner of the intersection of S. 144th Street and 42nd Avenue S. in the City of Tukwila, Washington. The environmental site assessment was authorized by the King County Library System (KCLS) and conducted by Landau Associates to evaluate the potential environmental risk associated with possible hazardous chemicals and other hazardous materials related to past uses of the site. These activities were undertaken for KCLS consistent with the "innocent purchaser" provisions of the Superfund Amendments and Reauthorization Act (SARA) of 1986 [42 U.S.C. 9601 (35)(A)(i)] and its state equivalent, the Washington Model Toxics Control Act (MTCA) [RCW 70.105D]. SCOPE OF SERVICES KCLS contracted with Landau Associates to provide the services described in a proposal letter dated August 5, 1992. Notice to proceed with these services was provided on August 6, 1992. The scope of services proposed and performed included: • Review of Site History. Research of aerial photographs, topographic and land use maps, county and city atlases, and other sources (as available), as well as conducted interviews of local, knowledgeable individuals to determine past uses of the site and surrounding area, and the potential for hazardous substances to exist on the property. A recorded Chain of Title was obtained from Chicago Title, which examined all known real estate transactions for the site dating from 1942 to the present. A copy of the report is presented in Appendix A. • Review of Agency Information. The City of Tukwila and King County departments, the Washington Department of Ecology (Ecology) and the U.S. Environmental Protection Agency (EPA) were contacted for available information in reports, files, and databases relating to the environmental quality of the site and surrounding area. • Site Reconnaissance. A site visit was accomplished in order to evaluate current land -use and environmental conditions, as well as to observe adjacent land uses. The reconnaissance did not indude an interior survey of the onsite house. STUDY AREA BOUNDARIES For the purposes of this environmental site assessment, we studied the area between S. 146th and S. 142nd streets, and between 41st Avenue S. and 44th Avenue S. 09/28/92 LIBRARY \FOSTFR.RPT 1 LANDAU ASSOCIATES. INC. SITE DESCRIPTION AND SETTING The approximately 1.5 acre, near -level site is located at the northwest corner of the intersection of S. 144th Street and 42nd Avenue S. in the City of Tukwila. The site location is illustrated on the Vicinity Map shown on Figure 1. It is bordered on the south by S. 144th Street, on the east by 42nd Avenue S., and on the north and west by single - family dwellings and apartments. The site slopes gently to the west and is covered with dense stands of alder and fruit trees, and areas of blackberry thickets and tall grasses. A single - family dwelling is situated near the northwest corner of the site. SITE HISTORY Information for the site history was obtained through the following sources: aerial photographs (H.G. Chickering 1961; Pacific Aerial Surveys 1961; Walker & Associates 1936 and 1946; and Washington Department of Natural Resources 1965, 1970, 1978, 1981, 1985 and 1989); topographic maps (U.S. Geological Survey 1968 and 1973); King County real estate atlases (King County Engineer 1983; Kroll Map Co. 1926, 1952, 1958, and 1987; and Metsker Map Co. 1926 and 1936); a history of Tukwila (Reinartz 1991); an interview with the current site owner (Seitz 1992); and real property assessment records obtained from the Puget Sound regional branch of the Washington State Archives. Site Uses Real property assessment records from 1936 show that a 1,152 ft2 single- family dwelling was built near the northeast corner of the site in 1908 and remodeled in 1925. The house was heated via a pipeless furnace and oil burner. Other structures on the site at that time included a chicken house and two supplemental farm buildings. The house was demolished by the current site owner between 1981 and 1985 (Seitz 1992). According to the King County records, another house, located on the northwest corner of the site, and heated with a wood stove, was constructed in 1944. However, the house is clearly visible in the 1936 aerial photograph. This is the same house that is presently on the site. The current site owner is Al Seitz, dba WMC Contractors, Inc., who has owned the site since 1978. The only significant use of the site, according to Seitz (1992), occurred for a few months in 1988, when bus shelters manufactured in Portland, Oregon, were stored and assembled onsite. He says that no welding, painting, or other uses of hazardous materials or substances were needed to accomplish that work 09/28/92 LIBRARY \FOSTER.RPT 2 LANDAU ASSOCIATES, INC. 139007.10 King County Lbrary SyslerNFosler Lbrary/Phase 1 ESA/Reporl 9'92 ... t, ) ..

INC. Adjacent Site Uses The area surrounding the site was initially developed around the turn of the century and, since that time, has primarily been residential— either single - family dwellings or apartment complexes and condominiums. The primary development in the study area has been Foster High School, located east of the site across 42nd Avenue S. which was built in 1953, remodeled extensively over the years, and then torn down in 1990, with new high school construction completed this month. AGENCY INFORMATION REVIEW The following agencies were contacted for information on the environmental quality of the site: • U.S. Environmental Protection Agency (EPA): Regional Office —A request for information related to all properties within the study area was submitted to the EPA regional office on August 18, 1992. In a response letter dated September 2, 1992, Michael Gearheard, Chief of the Waste Management Branch, noted that the Air & Toxics and Water Divisions have no information pertinent to the study area. His division's response included print -outs of the CERCLIS and RCRA databases for the zip -code which covers the study area. They are described in further detail below. • EPA: CERCLIS List (August 28, 1992)—Neither the site nor other properties within the study area have come to the attention of the EPA through owner notification, citizen complaint, state and local government identification, or EPA investigation as having a potential for releasing hazardous substances into the environment. • EPA: RCRA Notifier Report (August 20, 1992)— Neither the site nor other properties within the study area are included on this list of businesses that generate, store, treat, or transport hazardous substances. • EPA: Toxics Release Inventory (1987 - 1988) -- Neither the site owner nor other property owners within the study area have notified the EPA, as required of certain industries with 10 or more employees per Title I11 of the Superfund Amendments and Reauthorization Act of 1986, that they have released hazardous substances to the environment. • Washington Department of Ecology (Ecology): Northwest Regional Office — According to Public Records Officer Judy Fisher (1992), the regional office does not have any record of environmental problems on or near the site. • Ecology: Affected Media and Contaminants Report (July 1992) — Neither the site nor other properties within the study area are listed as state cleanup or potential state cleanup sites. • Ecology: UST Register (August 21, 1992)—Neither the site nor other properties within the study area have registered underground storage tanks. 09/28/92 LIBRARY\FOSTER.RPT 4 LANDAU ASSOCIATES. INC. • Ecology: Hazardous Sites List (February 25, 1992)— Neither the site nor other properties within the study area are listed as known state hazardous waste sites. • Ecology: Site Register (March 1990 - August 1992)— Neither the site nor other properties within the study area are listed in this register which informs the public of the latest activities on known hazardous waste sites. • King County Health Department: Hazardous Waste Division— According to Steve Burke (1992), the county does not have any record of contaminated soil problems on or near the site. • King County Health Department Kent District Office — According to Dave Koperski (1992), who oversees environmental complaints in the Tukwila area, no complaints have been filed related to the site or other properties within the study area. • Tukwila Fire Department: According to Fire Chief Nick Olivas (1992), the department does not have any record of fires or hazardous incidents on or near the site. SITE RECONNAISSANCE A reconnaissance of the site was conducted by a representative of Landau Associates on August 18, 1992. The following observations were noted regarding current land use and environmental conditions on and adjacent to the site. Site features are illustrated on Figure 2. Observations were documented with field notes and photographs. Onsite Observations • The undeveloped portions of the site are grown over by a combination of grasses, alder and fruit trees, blackberry thickets, and heavy brush. Dense stands of apple and plum trees exist on the eastern border of the property and blackberry thickets are predominate on the eastern and northern boundaries of the property. No visual indications of distressed vegetation or other unusual conditions were noted. • A wood frame single -family dwelling is located near the northwest corner of the property. The house is surrounded by thick ground cover and several apple trees. A circular driveway, surfaced with rock (quarry spall -size cobbles), approaches the house from S. 144th Street. A concrete pad, measuring about 30 ft long and 2 ft wide, is located on the south side of the house. An empty 55 -gal drum is situated on the pad and contains a minor amount of rain water. Four concrete sewer pipes are located on the north side of the house. A large pile of mattresses, wood scrap, metal scrap, yard waste, and household debris is located on the east side of the house. There is also scrap metal, scrap wood, and household debris under heavy ground cover in this area. Seitz (1992) says debris located east of the house was illegally dumped there in 1990. 09/28/92 LIBRARY \FOSTFR.RPT 5 LANDAU ASSOCIATES, INC. • 139007.10 King County Lbrary System/Foster UbraryPhase 1 ESA Report 9/92 ..knrvin!-n,e�x�: a,•r:em,>wre.- ,.us�,,,,�,,.

The house is serviced by electricity from 42nd Avenue S. and by city water and sewer lines from S. 144th Street. A lack of a visible vent pipe or fill cap implies that the house does not have an underground heating oil tank--the site owner says the house is heated by wood stove (Seitz 1992). • A hand -dug well with a 7 -ft deep concrete casement and concrete cap is located on the site. Sounding of the well shows a depth of 13 ft to water and a total of 26 -ft to the bottom from the top of the casement. No odor was apparent in the well and no sheen was observed on the water surface. • As part of the geotechnical investigation of the property, four test pits were excavated. No visual evidence of hazardous substances or odors were noted. The results of the geotechnical study for the site are submitted in a separate report. Adjacent Property Observations As part of the site reconnaissance, we observed land use and environmental conditions of adjacent properties in the study area. Specific observations include the following: • The area north of the site is residential in character, with a single - family dwelling located off the northeast corner of the site, remnants of an old cedar fence, and several large apartment complexes. • The area south of the site is residential in character, consisting primarily of single- family dwellings as well as several undeveloped lots. S. 144th Street parallels the southern boundary of the site and contains roadside debris, consisting of beverage containers, plastic, glass, and paper products. • The area east of the site is occupied by Foster High School and the current Foster Library site. Forty- second Avenue S. parallels the eastern boundary of the site and contains roadside debris, consisting of beverage containers, plastic, glass, and paper products. • The area west of the site is occupied by single - family dwellings. SUMMARY OF FINDINGS AND CONCLUSIONS The site history shows that a house was built near the northeast corner of the site in 1908 and was demolished between 1981 and 1985. In addition, another house has been located near the northwest corner of the site since at least 1936. Uses of the site have included single - family residential, residential orcharding and truck gardening, and, in 1988, the assembly and storage of bus shelters. The area surrounding the site was rural residential with truck gardens and small orchards until the late 1940s, when the surrounding area developed into a residential district. The major nonresidential activity in the study area is Foster High School, which was built in 1953. The recorded chain of title search did not reveal any information on past uses that would 09/28/92 LIBRARY \FOSTFR.RFT 7 LANDAU ASSOCIATES. INC. imply the use of Iazardous materials or substances, and it supports the finding that the site has been primarily used for nonindustrial and noncommercial purposes. A review of available agency information did not reveal any documented environmental problems with the site or properties in the study area. As observed in the site reconnaissance, a house occupies the northwest corner of the site. A small debris pile, a hand -dug well, a trailer, and a boat are located east of the house. Much of the site is overgrown with blackberry thickets, tall grasses, and fruit trees. The area surrounding the site is primarily residential, with the exception of Foster High School to the east. Based on our review of site history, review of agency information, and site reconnaissance, there is limited potential for contaminants of concern to exist on the property. However, there are three issues of potential environmental concern that should be addressed: 1) the potential that asbestos containing materials exist in the house, 2) the existence of a debris pile on the east side of the house, and 3) the existence of a hand -dug well also located east of the house. Specific recommendations for handling these issues are presented below. Based on the available information, it is our opinion that a Phase II study of the site that would include soil and groundwater sampling and chemical analysis is not warranted at this time. RECOMMENDATIONS Regarding the three potential issues of concern, we recommend the following: • Conduct an asbestos survey of the existing house prior to demolition. • Prior to site development, abandon the hand -dug well according to Ecology regulation 173 -160 WAC, Minimum Standards for Construction and Maintenance of Wells. According to this regulation, any well which is unusable, has been permanently discontinued, or is in such disrepair that its continued use is impractical or is an environmental, safety, or public health hazard must be abandoned and recorded and reported to Ecology. For hand - dug wells, clean chlorinated sand should be installed to a point 2 ft above static water level and the remainder of the well to land surface should be filled with clay, concrete, puddled clay, or bentonite. • Dispose of the debris pile at a permitted solid waste landfill facility, according to current local, state, and federal regulations. 09/28/92 LIBRARY \FOSTER.RI'T 8 LANDAU ASSOCIATES, INC. REGULATORY ISSUES Determining if a site has contamination at levels of concern is a matter of judgment. In Washington State, environmental liabilities in real estate transactions are regulated by MTCA. MTCA Cleanup Regulation, WAC 173 -340, defines the administrative process for identification, investigation, and cleanup of hazardous waste sites. It also includes detailed requirements for establishing cleanup levels, selecting cleanup actions, and determining compliance. Cleanup levels developed in accordance with WAC 173 - 340 -720 to 750, may provide some guidance as to the level of concentration of a hazardous substance that may pose a threat to human health or the environment. However, Ecology makes it clear that exceedances of the cleanup levels specified in Method A tables alone "do not necessarily trigger requirements for cleanup activities" (WAC 173 - 340 -704). The need for a cleanup action must also consider the nature of release, exposure pathways, and the nature of receptors. Until a method is developed to evaluate all these factors, an understanding of the cleanup levels, combined with best - professional judgment, will need to be used to determine whether a site poses a threat to human health or the environment, and, therefore, may potentially require a cleanup action under MTCA. USE OF THIS REPORT This Phase I environmental site assessment has been prepared for the exclusive use of KCLS. It is intended to provide KCLS with an understanding of the potential hazards that the site evaluated in this report may pose due to past chemical contamination. It describes what Landau Associates believes are reasonable concerns about how the site could potentially become involved in various environmental problems resulting from hazardous substances. This report is based on data and information obtained during one visit by Landau Associates personnel to the site, and is based solely on the condition of the site on the day of the visit, supplemented by information obtained by Landau Associates and described herein. In evaluating the site, Landau Associates has relied, in good faith, on representations and information furnished by the individuals noted in the report, with respect to existing site conditions and past uses of the site, to the extent that they have not been contradicted by site observations or data obtained from other sources. Accordingly, Landau Associates accepts no responsibility for any deficiency, misstatements, omissions, misrepresentations, or fraudulent acts of person interviewed. In addition, Landau Associates cannot accept liability for any loss, injury, claim, or damage arising directly or indirectly from any use or reliance on this report. 09/28/92 LIBRARYWOSTER.RPT LANDAU ASSOCIATES, INC.

Geotechnical Report dated September 29, 1993 by Landau Associates, Inc. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431-3670 • Fax (206) 4313665 Foster Library MDNS 6/6/94, Page 2 DESCRIPTION OF THE PROPOSAL The applicant proposes to construct a new neighborhood library on a vacant 1.15 -acre site. The site is located in a single - family residential zone. The 5,520 square -foot library will include a covered entry leading to a lobby, a 70- person Multi- Purpose Room, staff offices and restrooms. The building will be 24' in height, with exterior of brick, stucco /Dryvit in earth tones, simulated stone, and painted metal accents. Site improvements will include a 35 -stall parking lot; landscaping, including large stature street trees and screening shrubs; biofiltration swale; and a curving entry walk with a seating wall. There will be parking lot lighting with down -ward directed fixtures. Street improvements are also planned, such as a 6' wide curbside sidewalk and street trees along 42nd Avenue South and South 144th Street. This new facility will replace the existing Foster Library located 1/2 block away on 42nd Avenue South. PRINCIPAL CHECKLIST ITEMS A. EARTH Other than a 2 -3' elevation gain from the street, the site is essentially flat. Construction debris from a demolished house has been previously removed, and an old well capped. No import or export of material to /from the site is expected. Based on this, no noticeable impacts are anticipated, and no mitigation is necessary. B. WATER There are no permanent surface water bodies on or near the site. Most of the site will be covered with impervious surfaces. Storm water runoff will be addressed using the existing system along South 144th, with the addition of an on -site biofiltration swale. The 6" water main on South 144th is sub - standard in size. C. PLANTS The site has previously been cleared and developed. Existing vegetation on site consists of mostly grasses and shrubs, and several large existing trees. Most of this vegetation will be replaced by new landscaping. A large, mature American elm is proposed to be retained, but it may not survive the impacts of construction and paving on root areas. Approximately 11 red alders along the northern Foster Library MDNS 6/6/94, Page 3 edge of the site will be retained. The proposed landscape design also includes large stature trees within the site and along the streets. .Measures to ensure survival of "retained" trees should be included in the plans. Other mitigative measures should be evaluated through Design Review by the Board of Architectural Review, as noted below. D. NOISE The new library will likely generate more noise than that typically associated with residential areas. Some mitigative measures are proposed. The building and main entrance is located as far as possible from residences. Where single family residences abut the west side of the site, there will be a 40' wide landscape buffer. Elsewhere, parking areas will be buffered by a 10 foot landscape area. Noise will also be reduced by the library's limited hours, which will typically be from 8:00 a.m. to 8:00 p.m. Other mitigative measures should be evaluated through the Conditional Use Permit process. E. LAND USE The proposed library will be located in a residential zone, with residences nearby. As a non - residential use in a residential area, the library proposal raises concerns regarding auto and pedestrian circulation, compatibility of building architecture with the neighborhood, screening and landscaping, lighting and signage effects, and its aesthetic and functional relationship to the high school. As the library will be located in a residential zone, it will require a Conditional Use Permit. Potential impacts of the proposal will be evaluated through this process. However, specific impacts and mitigative measures should be evaluated in more detail through Design Review by the Board of Architectural Review. Through Design Review, the site plan and design details can be refined to provide the best fit with the surrounding neighborhood. F. AESTHETICS The project is expected to have an effect on the aesthetic character of the neighborhood. Compatibility with the neighborhood would be best addressed through the required Conditional Use Permit and through the public Design Review process. Foster Library MDNS 6/6/94, Page 4 G. LIGHT AND GLARE The new library has the potential for light spillover and glare not typically found in a residential zone. Parking area lights and headlights from frequent traffic could affect adjacent residences. Such effects should be addressed using appropriately - designed lighting standards, landscape screening, and /or solid perimeter fencing. The effectiveness of these measures should be evaluated in greater detail through the Conditional Use Permit and Design Review processes. H. RECREATION The Tukwila Parks and Open Space Plan encourages the development of outdoor non -city recreation facilities. In addition, the Tukwila Comprehensive Plan encourages locating public recreational facilities within easy access to residents. Based on these policies, the new library should provide quality outdoor areas for the public. To ensure that the library proposal meets City policies for passive recreation, plans should be further evaluated through the Conditional Use Permit and Design Review processes. I. TRANSPORTATION /TRAFFIC It is estimated that the new library would generate approximately 250 (125 in, 125 out) vehicle trips to roads in the project area. Some of these vehicle trips will be additional over traffic generated by the existing library. Vehicles will use two driveways into the site, one of which will be new. The existing four -way stop at the intersection of 144th Street and 42nd Avenue will remain. The right -of -way along South 144th Street is substandard. In accordance with Tukwila Ordinance No. 1616, the property owner will be required to dedicate an additional 10 feet of right -of -way. Sidewalks are included in the proposal. Based on this, no significant traffic impacts are anticipated, and no mitigation measures are necessary. MITIGATED CONDITIONS OF APPROVAL Issuance of a Mitigated Determination of Non - Significance is appropriate, as the environmental review indicates no probability of significant adverse environmental impacts from the proposal.

Simpson Jack Pace z (A3 TUKWILA TOMORROW November 18, 1993 LAND USE ELEMENT PACIFIC HIGHWAY Anna Bernhard Adele Scott Betty Gully Bill Arthur Grant Neiss Jack Scott John Welch Moira Bradshaw PACIFIC HIGHWAY Moira: At the last meeting we left off with Policy 14. I had started talking about the issue of site design and circulation. We were talking about how parking placement and setbacks should be different along the corridor to emphasize a Center versus an automobile oriented area. That's when it was suggested to create a heart, to know when you are at the center of a neighborhood. That's where we left off. There was also a request to go back to policy 12 as well. Have you marked which policies you had questions on? Should we go ahead and list them? Do you want to check that at the next meeting and run through them as we have historically at this meeting? Agreement. Site Design and Circulation Policy 14: Design and combine parking placement and setback /build to standards to achieve: - concept of contrast between compact center and low rise linear corridor, - consistent street wall in both areas, and - pedestrian attraction. Moira: My impression of what was being discussed last time, was that you didn't think that having buildings and activities along the street corridor would create a sense of arrival and place at the intersection of 144th and 99. November 18, 1993. Page 2 Comment: I think you could do special treatments like cobblestone which would give a sense of arrival. I wasn't clear as to exactly what was being imagined to be done. Comment: I think that's what was being discussed. Not having the buildings come up and make it be. a square corner, but cut back. Moira: Your options are to have parking or a building in the area, or a plaza. As we mentioned, there is only so much area on . these blocks. How big the plaza should be, is the question. Question: Why can't you terrace it as you go up so it opens it up? Moira: I'm not sure if Bill was completely against the idea of a building here. Comment: I thought he was against squaring the buildings right up to the curb. Comment: I think we should address the idea of having a center feeling with some sort of treatment, something to make you feel that you are at the center. Moira: So the suggestion is that we have a policy under design review that talks about achieving a sense of being in the center of town. Comment: If we haphazardly place some buildings back and others forward, we get a "junky" look. Moira: I think the thought that everybody agrees upon is that the improvements to this area should relay that this is the center of the residential neighborhood, this is the neighborhood center. We can have a policy on that. Comment: Not just that intersection, it needs to run down and include the area of the high school also. Comment: You said the parking was in direct conflict with the open space concept. The parking lot at Larry's Market gives a feeling of openness. The landscaping has a very pleasing effect. I don't know that parking is necessarily bad, it is harmonious with the open feeling. • Moira: The idea that is trying to be expressed here, is to convey a sense of arriving, a heart of a neighborhood, an area. That means that something different occurs here than elsewhere on 99. A way of doing that is by doing something different with the placement of your buildings. Actually using the buildings as a means of conveying that difference. Also, we have said that from here south it's slovember 18, 1993 Page 3 J • more auto oriented. When you have a building pressing on a street, you also have a • sense of the activity and that there are businesses that are there. It's that contrast that's being suggested for this area as a means of distinguishing it. We have a policy under projects that says, "Tukwila shall improve 144th between 37th and 42nd including right -of -way acquisition." There has been a good suggestion to add a policy regarding the design of the structures to include pedestrian amenities. If you agree that buildings are appropriate in this area versus a parking lot, then a suggestion of a policy on the treatment of these buildings would be appropriate under design review. Question: So policy 14 is saying that it should be close zero setbacks with parking along side or behind? Moira: And that there ought to be something different elsewhere - in the mixed use, regional section of the corridor. Question: How would we really achieve this? Over many many years? Moira: Yes, anything that will happen there, will be achieved over time. Comment: You can't impose anything on anybody until they've decided to redevelop. Question: I am not opposed to this, but can we really get there from here considering what we have? Comment: We talked last week about backing everything up both from the street and the intersection, instead of squishing everything and looking at just the intersection. Use the new . Foster High and the new Larry's Market to build from, and make that your parameters of this new town square. Dandy's and the motel are likely candidates for redevelopment, which is the whole east side of 99. The things that will get in your way are the things that aren't there yet, specifically the new library. That may not be the best location for that library if you adopt a concept like this. Moira: The City of Tukwila made a choice to keep two separate libraries. There can only be so much square footage for each location. Comment: Until its built you can still resite it. Comment: I don't understand why its wrong for that location. November 18, • 1993 Page 4 Comment: Because it is so tiny, it makes it hard to do something for the whole area. Comment: I think the road is too narrow to the east. Moira: Why do you think its too narrow? Comment: You have limited site, the motel comes right up to the corner. There are people walking on a small sidewalk, barely enough room for the cars. Moira: We have the suggestion that it be opened, that there be acquisition of a right -of -way and a pedestrian corridor which would mean at least a ten foot sidewalk. Comment: There's a chance, if you really want to make a statement, that you could do one of those loops like you have in some towns elsewhere. At least you could identify this as an area; something unique in Tukwila. Question: If you were going to take the library out of there, what would you suggest to replace it with? Comment: There are two neat things going on there with the high school and Larry's Market. If you could widen the area there, I'm not sure you would want anything. Comment: Further north on 42nd, this committee was quite adamant about leaving a buffer zone between the business section and the people across the street. To me that library would be an ideal use for a buffer zone. Moira: If you do something grander and more public here, then you would be eliminating some of the existing commercial and residential lots. This whole area would be commercial on the ground floor, then residential as you go up. One of the things people will want when they develop, is enough land. These lots, as were mentioned in the report, were plated for single family lots. That happened before the 1920's. One point that the economic consultant made was that there's a lot of little lots, a lot of ownership. To get redevelopment you will have to provide more area for some of the lots and /or they will have to be consolidated. That is a different concept. The point that has been made is, do we do something more public instead of relying on private investment? Comment: I don't agree with that. I don't think you necessarily need to acquire property from the developer using certain design standards. Si((ovember 18, 1993 Page 5 Moira: You said that the area would be open, how can you do that without buying 'property? Comment: • You do it like they do it in Bellevue. They impose design standards on developers and in exchange they can go up higher. At One Bellevue Center, there was not additional acquisition of right -of -way other than for the street. You will find that the corners are inset, approximately 35 feet. It is not a public area, it remains • in private ownership, but you do have a park like setting with steps. Moira: So what 1 see then is to continue to use buildings to create the sense of a center, but to treat the buildings such that you get significant public areas along the street frontage and 144th. Comment: When you think about it, practically every intersection is. Look at the transit center and the Cole Center building. Look at the Hyatt, they allowed retail right up to the sidewalk, and then an open space in the form of a circular plaza drive through pedestrian area, where the hotel meets the office buildings. Comment: Last week I was trying to portray that concept by describing buildings downtown. You said the difference with that is that in downtown they can go up really high and make up the difference. I like this concept, can it be done? Comment: As you go further over the hill towards the freeway the floor -area ratio wasn't a consideration. They have more park down there and they have it on both sides. Moira: This is a great idea, but I think there is a quantitative aspect to this of how grand is going to be grand enough. You need to do some more imaging of exactly what that means, so that when someone comes in to design a project your intentions are clear. Economically I am not sure of the amount of area that's devoted to these public spaces and the amount left within the block to put in enough building square footage to do something feasible. That is something we will be doing more analysis on. Comment: There is one thing when you picture a building. On the first floor there is a lot of open space and setback. When you get up to the second floor, the floor plate from street level, then you go back to regular size. Moira: Are you saying to cantilever over? Comment: Not all the way to the corner, just over the plaza area. November 18, 1993 Page 6 Comment: In the buildings downtown they used a lot of glass on the lower section. Some of them are out, the corner is cut off. You get the illusion of being open. Comment: I think we are in agreement that we want it to have a sense of a town center, a sense of center. There have been a variety of suggestions of ways to get there. What could we say in our policy that would address the things we talked about? Moira: • I would suggest that under policies on page 38, where we have design reviews, that there be an additional policy in there that talks about how this neighborhood center shall act as a town focal point, and that the building walls shall be setback to create public spaces and an openness that provides a corridor both east -west between 37th and 42nd and between 140th and 148th. In essence you would have a building wall, but the wall would be setback to create public spaces. You will have substantial areas of glass and interesting building fronts. Comment: I don't know if we should say that building walls shall be set back because there are so many ways to achieve that. Moira: So we can say that public spaces shall be created within this area and there will be a feeling of openness. Question: Do you want to say public spaces? That implies that you will use public funds to acquire it. • Moira: This is under design review, where we will be telling the people that are developing buildings. Comment: A place where people can gather. Question: What about pedestrian corridor areas? Jack: So you are looking for a term that conveys that it's not a traditional private property like the mall corridors, a quasi - public space. Moira: We can • say "privately developed and maintained public spaces." Comment: The main thing is that you aren't using public funds and you aren't acquiring public property. Comment: This could be a chance for a neighborhood commercial area and a cultural area to be united together with a public space at 99 and 144th and a public space at • .,;(ovember 18, 1993 Page 7 144th and 42nd. Whatever you develop in between, you have these two areas that could be tied together. Moira: Does it seem like we're on the same wave length? There may be substitutions for some of the ' words, but the concept is privately developed areas used by the public. Comment: Does that square with page 32, the middle of the page where it says, "Fundamental to designing for pedestrians and making transit use as pleasant as possible...." Comment: 1 guess the only thing lacking is what do the developers get in return? There should be some tradeoff. Moira: What tradeoffs are you willing to give? Comment: Height. Moira: You already said it could be three stories, are you saying that they could have more? Comment: Yes. The design and form standards are being set by the high school. Agreement to create policy in design standards for this intersection. Moira: Do you want to go back to policy 12 now or later? Comment: 1 was happy with what Tim proposed last week. Moira: What 1 have is, "To locate transit facilities within the SR 518 -99 interchange. Comment: Actually what Tim proposed last week was, "locate transit facilities and /or rail station in the SR 518/99 vicinity." Moira: And leave off the rest? Comment: No, include the rest of the policy as written in the report. Agreement to have policy 12 read, "Locate transit facilities andlor rail station in the SR 518199 vicinity and develop a multi -modal transfer area for buses, automobiles and pedestrians."

Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 3 BACKGROUND The community has been informed of the Foster Library project in several ways: • Notice mailed to residents within 300 feet; • Notice published in newspaper; • Notice posted on site; • Articles in February and June 1994 Hazelnut; • Status update letters mailed to residents within 300 feet; and other interested parties (6/8/94, 3/14/94, 1/26/94). • Information meeting with Tukwila Library Board 2/1/94; • Public information meeting 2/15/94. Approximately 20 residents attended and the February public information meeting. Many residents filled out comment sheets. Although residents reviewed the original design, many of their comments are applicable to the new design. Public comment sheets comprise Attachment L. The project SEPA environmental review was completed 6/10/94. A Mitigated Determination of Non - Significance (MDNS) was issued with a condition that trees proposed for retention must be adequately protected during construction. In addition, the MDNS required the project to undergo Design Review, as follows: 'To more specifically address potential impacts and to ensure compatibility with the surrounding neighborhood, the library design shall be further refined through the Conditional Use Permit and Design Review processes. The proposal shall include for Board of Architectural review the following revisions: a. To reduce light spillover into adjacent residential lots, the west and north perimeter of the site shall have a solid decorative fence and /or opaque landscape screening. b. Given Tukwila policies regarding outdoor recreation, the proposal shall provide quality outdoor areas for the public." Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 4 DECISION CRITERIA Under the Zoning Code, a library must obtain Planning Commission approval for the amount of parking provided (TMC 18.56.050). As a non - residential use in a residential zone, the library must also obtain a Conditional Use Permit (TMC 18.12.050, under criteria in TMC 18.64.050). Approval by the Board of Architectural Review (per TMC 18.60.050) was required in the SEPA environmental decision. This same process of Conditional Use Permit and Design Review was required for Foster High School. The Sign Code requires Planning Commission approval of public facility signs in residential zones (TMC 19.32.080). Given the above requirements, the applicant is requesting four approvals: I. Special Permission for the amount parking provided; II. Conditional Use Permit approval; III. Design Review and approval of the library design; and IV. Special Permission for the design of signs (included as part of Design Review). Accordingly, the staff report is divided into four parts: Special Permission Parking; Conditional Use Permit Criteria; Design Review Guidelines; and Special Permission for Public Facility Sign. Review criteria for each of these approvals are shown below in bold, followed by staff's summary. The applicant's written responses to the criteria are given in Attachments J, K. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 5 I. SPECIAL PERMISSION: PARKING (TMC 18.56.050) "The minimum number of off - street parking spaces for "public facilities, including libraries...shall be determined by the Planning Commission" (TMC 18.56.050). The applicant has provided parking information from other libraries which can be compared with parking for Foster Library (see Attachment E). According to this parking chart, 7 other libraries of similar size (5,000 -6,000 s.f.) have an average of 26 parking stalls. Foster Library will have 34 stalls (see Attachment B). The Meeting Room in these libraries has an average capacity of 51 people. In comparison, the Foster Library Meeting Room has a 70- person capacity (see Attachment D). It is likely that, at times of high use, some library patrons will park off -site along 42nd Avenue or at Foster High School. CONCLUSIONS: Based on information from the applicant, the amount of parking provided at Foster Library is comparable to that provided at other libraries. Therefore, no additional on -site parking is needed. RECOMMENDATIONS: As on -site parking is adequate, staff recommends approval of the amount of parking provided in the proposal. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 6 II. CONDITIONAL USE PERMIT CRITERIA (TMC 18.64.050) 1. The proposed use will not be materially detrimental to the pubic welfare or injurious to the property or improvements in the vicinity of the proposed use or in the district in which the subject property is located. The proposal provides an amenity to the neighborhood. The site plan, building design and landscaping reduce potential impacts. For example, substantial landscaping has been added, and a biofiltration swale will improve the quality of stormwater runoff (see Attachments B, C, D). 2. The proposed use shall meet or exceed the performance standards that are required in the district it will occupy. The library building has a lower height and greater setback than required in the Single Family Residential zone The proposal includes landscaping buffers of 10 -foot width or more, even though no landscaping is required. 3. The proposed development shall be compatible generally with the surrounding land uses in terms of traffic and pedestrian circulation, building and site design. The new library would generate approximately 250 (125 in, 125 out) vehicle trips to roads in the project area. This is probably more traffic than the existing library, but less than what the high school generates. Vehicles will use two driveways into the site, which will be marked with pedestrian crossings. Sidewalks are included in the proposal. The existing four -way stop at 144th Street and 42nd Avenue will remain. Tukwila Fire and Public Works Departments have approved the proposed traffic and circulation patterns. The building and main entrance are located as far as possible from residences. Where single family residences abut the site, there will be wide landscape buffers. Noise will be minimized by the library's limited hours, typically from 8:00 a.m. to 8:00 p.m. Monday through Saturday. These characteristics help reduce potential impacts. However, as a non - residential use, the library has the potential to affect adjacent residential areas. Landscape screening and fencing are not provided along all edges. Residents have expressed concern about potential light spillover and glare. To address this, the project's SEPA decision required improvements in perimeter screening, through landscaping and /or a decorative opaque fence. Approval of Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 7 details was deferred to the Board of Architectural Review. In addition, the project has the potential to affect the aesthetic character of the neighborhood. This will require a more detailed evaluation. The Design Review process provides an opportunity to address screening and aesthetic issues in detail. Design Review was required as a condition of the project's MDNS. 4. The proposed use shall be in keeping with the goals and policies of the Comprehensive Land Use Policy Plan. Tukwila's current Comprehensive Plan includes policies intended to protect residential areas from non - residential uses. With some refinements in landscape screening and building design, the proposal can be consistent with these policies (see Criteria #3, above). 5. All measures have been taken to minimize the possible adverse impacts which the proposed use may have on the area in which it is located. The proposed site plan, building design and landscaping reduce most, but not all, potential impacts (see Criteria #3, above). CONCLUSIONS: 1. The proposed use will not be materially detrimental to the public welfare.... The site plan, building design and landscaping have been designed to reduce impacts to the neighborhood, and to provide an amenity. Therefore, the proposal will not be injurious to the public welfare or its surroundings. 2. The proposed use shall meet or exceed the performance standards that are required in the district... The proposal meets and exceeds the standards of the single - family residential zone. 3. The proposed development shall be compatible generally with the surrounding land uses... Traffic and pedestrian circulation have been adequately addressed. The proposed building design, site plan, landscaping and screening, have the potential to be compatible with the surrounding area. The specific way in which potential impacts are addressed can be resolved through the Design Review process. r Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 8 4. The proposed use shall be in keeping with the goals and policies of the Comprehensive Plan. The proposed library is generally consistent with existing Comprehensive Plan policies which require protection of single family residential areas. 5. All measures have been taken to minimize the possible adverse impacts which the proposed use may have on the area in which it is located. As noted under Criteria #3, the plans do not satisfy all aesthetic and landscape screening concerns. This can be addressed through approval of refinements in the Design Review process. RECOMMENDATIONS: Due to the fact that, with additional refinements to be approved through Design Review, the project generally meets the criteria, staff recommends approval of the Conditional Use Permit. r Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 9 III. DESIGN REVIEW CRITERIA (TMC 18.60.050) 1. Relationship of Structure to Site. The site should be planned to accomplish a desirable transition with the streetscape and to provide for adequate landscaping and pedestrian movement. Parking and service areas should be located, designed and screened to moderate the visual impact of large paved areas. The height and scale of each building should be considered in relation to its site. In the site plan, the building is located close the street corner and oriented to the west (see Attachment B). This has several advantages. A corner location gives visual prominence to the relatively small building. This is especially important next to the large high school. Another advantage is that the building helps to screen the parking lot. Locating the building away from residential areas may also help reduce potential conflicts. The orientation of the main entrance allows combined access for both cars and pedestrians. The plan also accommodates the typical motorist use of the book drop at the main entrance. For this building orientation to be 'successful, the "rear" facades along the streets and the entry must be carefully designed. Otherwise, the library could appear to "turn its back" on the neighborhood, instead of being inviting. The applicant has emphasized the main entrance with a portico (porch) and entry plaza. A wide entry walk with sitting wall at South 144th Street helps to provide a memorable arrival to the library. Building facades have been revised to include windows and details which help make the building more inviting to the neighborhood (see Attachment C). 2. Relationship of Structure & Site to Adjoining Area. Harmony in texture, line and masses is encouraged. Appropriate landscape transition to adjoining properties should be provided. Public buildings and structures should be consistent with the established neighborhood character. Compatibility of vehicular and pedestrian circulation patterns and loading facilities in terms of safety, efficiency and convenience should be encouraged. Compatibility of on -site vehicular circulation with street circulation should be encouraged. The library site is surrounded by a variety of uses. To fit its context, the library design must relate to single and multiple - family residences of various ages and Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 10 styles, and to the "civic monument" scale of the adjacent high school. The applicant has chosen a theme for the building which includes references to features in the high school building, such as columns and portico (see Attachment H). At the same time, the library has a height and scale which is more residential in character (see Attachment C). Durable exterior materials in earth tones are proposed, which are compatible with the subdued character of nearby residences (see Attachment I). The landscape plan provides buffers next to residences, while the "public" sides of the building are more formal and open. Access is from the north or south via two driveways and entry walks. Sidewalks are provided. However, the library entry is handicapped accessible only from the remote. north walkway. 3. Landscape and Site Treatment. Where existing topographic patterns contribute to beauty and utility of a development, they should be recognized, preserved and enhanced. Grades of walks, parking spaces, terraces and other paved areas should promote safety and provide an inviting and stable appearance. Landscape treatment should enhance architectural features, strengthen vistas and important axes, and provide shade. In locations where plants will be susceptible to injury by pedestrian or motor traffic, mitigating steps should be taken. Where building sites limit planting, the placement of trees or shrubs in paved areas is encouraged. Screening of service yards and other places which tend to be unsightly should be accomplished by the use of walls, fencing, planting or combinations of these. Screening should be effective in winter and summer. In areas where general planting will not prosper, other materials such as fences, walls, and pavings of wood, brick, stone or gravel may be used. Exterior lighting, when used, should enhance the building design and the adjoining landscape. Lighting standards and fixtures should be of a design and size compatible with the building and adjacent area. Lighting should be shielded, and restrained in design. Excessive brightness and brilliant colors should be avoided. Quality public buildings, especially a community library, have two distinguishing characteristics. First, they take advantage of opportunities for lively outdoor public spaces and public artwork. Both the City Council and Arts Commission have expressed enthusiasm for such spaces in the new library. Second, they provide a main entry which is visually strong and provides a memorable "procession" to the library from the street. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 11 Public spaces and main entry: The Foster Library proposal provides one main outdoor gathering area, incorporated into the entrance. There are 3 to 4 areas which can accommodate future artwork. The proposal emphasizes the main entry through wide entry steps and sitting wall leading to an entry plaza. As a place for both gathering and for artwork, the entry design adds appeal to the project. Detailing: As noted by the applicant, the landscape plan responds to the architecture and site plan in several ways. However, relationships between some elements are not clear. For example, the oblique angle shape of the entry plaza does not appear to relate to any angle in the portico or the steps. The diagonal row of poplar trees is bold and visually interesting. Yet, the diagonal does not have a visible counterpart in building design. This is also true of the diagonal in the entry steps. Planters at the entry have interesting shapes, but it is not clear if they include retaining walls which follow grade changes. Many of the details which clarify design intent or add quality to a design are not evident in the plans. For example, details of the sitting wall would indicate whether it functions as an inviting area (with appropriate height, width, etc. for sitting). Contrasting paving materials or colors in the entry steps and entry plaza would add emphasis to the entry. As noted earlier, the main 'entry is not convenient to handicapped patrons approaching from the west. In other locations, it is not clear what type of plants are proposed. The landscape plan lists several different, dissimilar plants for the same symbol (e.g. daylilies and holly). As noted in Section II, Conditional Use Permit, it is not clear whether adequate screening (with landscaping or fencing) is provided along all residential areas. Additional issues in the landscape plan: • Several existing trees are proposed to be saved. Although the large elm is to be retained, it is likely to have most of its roots damaged by parking lot construction. Usually, adequate tree protection involves protection of at least the area under a tree's canopy. The planter around the elm's base is 8 feet wide. • While the dumpster /transformer area is screened, the configuration of the wall and lack of lighting next to the staff entry raise safety concerns. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 12 • • A street light is located in the middle of the entry walk (near the street intersection). • A "biofiltration swale sign" (presumably for interpretive purposes) is located in an area which is not very visible or accessible. • As the application drawings are not intended for construction, no irrigation is proposed yet. Site lighting: Light standards (total of 5) are proposed along entry drives and in the parking lot. It is not clear if this is adequate to safely light .the area. No lighting is proposed to accent the building, walkways, or landscape features. 4. Building Design. Architectural style is not restricted, evaluation of a project should be based on quality of design and relationship to surroundings. Buildings should be to appropriate scale and be in harmony with permanent neighboring developments. Building components, such as windows, doors, eaves, and parapets, should have good proportions and relationship to one another. Building components and ancillary parts shall be consistent with anticipated life of the structure. Colors should be harmonious, with bright or brilliant colors used only for accent. Mechanical equipment or other utility hardware on roof, ground or buildings should be screened from view. Exterior lighting should be part of the architectural concept. Fixtures, standards and all exposed accessories should be harmonious with building design. Monotony of design in single or multiple building projects should be avoided. Variety of detail, form and siting should be used to provide visual interest. Two characteristics of high quality buildings are 1) high quality materials, and 2) attention to details. Quality materials are especially important for a small-scale building like the library, where the relationship with the user is more intimate and details are seen close up. Details also become important when a building, such as the proposed library, has a simple shape with little exterior modulation. Exterior materials: Foster Library's exterior will have a combination of several materials (see Attachment I). Brick veneer and stucco -like Dryvit will predominate. The overall !. -- Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 13 colors will be warm, earth tones. Accent features such as columns, doors, and windows will be finished in metal painted a contrasting color. "Medallions" (large tiles stamped with a design) are used as accents on two facades. Detailing: The applicant has explored ways to incorporate interesting patterns into the library exterior. For example, downspouts and columns have been added which provide vertical modulation. On the east facade, windows and medallions are arranged in rhythmic patterns. The medallions themselves could become sculpted artwork. In addition, windows have been added wherever possible. This provides modulation in an otherwise box -like structure, and makes the building more inviting from the street. Windows also enhance nighttime appeal of the site and building. The large window which wraps around the SE corner is a distinctive feature of the library. In concept, such features have the potential to give the building variety and warmth. However, the proposal has such variety that each facade is very different than any other. Some features and patterns are repeated nowhere else. For . example, the pattern of medallions on the east facade is not repeated elsewhere; some doors have medallions overhead, while others do not. The large windows at the north and SE corner are different from each other, and have a very different style than other windows. The shape of the large window is on the west facade is not found elsewhere. Entry portico: One of the key features of the library is the entry portico (see Attachment C). As previously discussed, the entry steps and plaza help provide a meaningful outdoor space and "sense of arrival." The entry portico is an integral part of this important area. The portico is formed by the cornice, supported by two columns. Its roofline is flush with the building. The columns used in portico do not match each other, nor the column at the SE corner, and are not used in other areas. Cornice: Another distinctive element of the building is its cornice. The cornice has multiple layers, which create visual depth in the facades, and a solid cap for the building. The cornice is unusual in that it does not extend around the entire building. It stops and starts in a different way on each facade. In places, the cornice appears to be "supported" by narrow rain downspouts. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 14 Building lighting: An important community building, used and visible after sundown, can continue to provide architectural appeal through an imaginative lighting design. However, the proposal does not take advantage of this opportunity. 5. Miscellaneous Structures & Street Furniture. Miscellaneous structures and street furniture should be designed to be part of the architectural concept of design and landscape. Materials should be compatible with buildings, scale should be appropriate, colors should be in harmony with buildings and surroundings, and proportions should be to scale. Lighting in connection with miscellaneous structures and street furniture should meet the guidelines applicable to site, landscape and buildings. The library proposal includes one bench at the entry, along with a sitting wall. Bike racks, trash receptacles or other street furniture are not indicated. CONCLUSIONS: 1. Relationship of Structure to Site. Proposed landscaping and sidewalks generally provide an appropriate transition to the street, and screening of service areas. The height and scale of the building are appropriate for the site. However, the entry does not have enough visibility or refinement to counteract the building's inward orientation. This could be accomplished with refinements in the entry plaza and portico (see Landscape Criteria and Building Design Criteria). Refinements in windows and details will help the building appear more inviting to the neighborhood (see Building Design Criteria). 2. Relationship of Structure & Site to Adjoining Area. The building generally fits its neighborhood setting. However, additional landscape screening is needed next to residences (see Landscape Criteria). Vehicular & pedestrian circulation is generally logical and safe, although convenient barrier -free access is needed (see Landscape Criteria). In addition, two minor revisions would be appropriate: a) there appears to be no need for both scored concrete and traffic buttons at the driveways; and 2) the curve in the north sidewalk appears odd and unnecessary. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 15 3. Landscape and Site Treatment. The applicant has provided, in general, a quality landscape plan. However, the plan needs additional refinement to clarify design intent, to strengthen underlying concepts, and to resolve unfinished details. The main areas needing refinement are noted below. Public space and entry: The proposal provides the beginnings of a high quality "people place." The entry steps and sitting wall have the potential to provide an amenity for patrons, and create an appealing processional experience from the street to the library. With more emphasis, the entry plaza could become a memorable focal point. To achieve its potential, the entry area needs more detailing and refinements. These are noted below and shown in Attachment F. Detailing: The entry plaza needs to be re- designed with a size and shape which is better related to the portico, steps, and other site features. This could include sharpening the plaza's angle to 90 degrees, or matching the diagonal in the row of poplars, enlarging the plaza, and /or changing the shape of the portico (see Attachment G). Refinements in the entry plaza should include the landscape planters. The grades of the entry planters need refinement to better relate to the entry plaza and portico. In addition, contrasting paving at the entry plaza would help emphasize the area more inviting. Contrasting colors or banding could be used to tie the plaza to the steps or the cap of sitting wall. The sitting wall concept is very appealing; however, it needs to be detailed to function well as a sitting wall. The wall should be an appropriate height (approx. 18 ") and have a wide enough cap for sitting. Proposed walkways are generally safe and attractive. However, the entry plaza/walk should be re- designed to incorporate barrier -free access. As the planting plan is not specific, it is difficult to draw conclusions regarding quality and aesthetic effects. Plans should clarify which plant species will be used where (e.g. whether street trees will be ash, maple or both). Solid perimeter fencing and /or opaque landscape screening are needed to address potential light spillover to residential areas to the north and west. For a community building surrounded by residential uses, fencing should be of decorative material and quality construction (i.e. not chain link). Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 16 Other landscape plan refinements: • To help ensure the survival of the large elm, the surrounding planter should be enlarged. This could result in 1 -2 fewer parking stalls for the project. However, a 32 -33 stall parking area would be consistent with parking provided at similar libraries. • The dumpster /transformer area wall and landscaping should be re- examined for alternatives which increase safety. The area should include adequate lighting. • The street light located in the middle of the entry walk will interfere with pedestrian circulation. It also visually interrupts the nicely- designed street corner. It should be relocated to the nearby landscape planter or other more logical place.. • The "biofiltration swale sign" is an appealing idea, which could get lost in its present location. The sign would be more effective if moved closer to the entrance or edge of parking lot. • Irrigation of all areas, including street planting strips, is necessary to ensure plant survival. Irrigation plans should be submitted for approval with building permits. Site lighting: Lighting does not appear to be adequate for safety. It is also not designed to enhance site features. For example, lighting standards are not of an attractive style and scale for walkways. The plan misses other opportunities; for example, the row of poplars or the sitting wall could be dramatically lighted. 4. Building Design. Foster Library will be an important and highly visible building in the community for years to come. Recognizing this, the applicant has revised the design several times to improve its quality. For example, the new design has an appropriate relationship to Foster High School, and has a residential scale which fits the larger neighborhood context. Exterior materials have a durability and richness suited to a civic structure. The geometrical shapes of windows and other elements have the potential to create a bold and interesting building. The revised design begins to address the need for a quality civic project. However, refinements are needed. Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 17 Detailing: The proposed building does not have a level of refinement appropriate for this type of facility, with appropriate scale, detailing, and internal consistency between architectural elements. For example, rain gutter downspouts are too small for important vertical elements, and appear to be "dangling" from the cornice. The downspouts do not appear to use quality materials. Medallions and windows are not well - framed. As a result, their potentially interesting patterns tend to get lost. Lack of internal consistency gives the building an overall appearance of disharmony. For example, the large windows at the north and SE corner do not relate to each other, and have a very different style than other windows. The medallions are not used consistently. The west and south facades appear to be unrelated. To address these issues, the applicant needs to fine -tune the building details. Areas which need special attention are noted below, and shown in Attachment G. • Downspouts should be re- designed as an integral part of the architecture, with a better match to other vertical elements of the building. Possible solutions: enlarge and cover with pilasters /columns; use accent colors; wrap the base of the building around the downspouts. • The transition between medallions, windows and vertical elements should be detailed to better define their edges and patterns. Possible solutions: add frames; add contrasting materials; deep insets to create shadows. • Repetition of patterns or similar elements should be used to provide more internal consistency between architectural elements. Possible solutions: repeat the medallion pattern; use downspouts or columns on other facades; extending the cornice around the entire building. • Refinements in the windows would also make the building more harmonious. Possible solutions: extend the north window to the building base like the SE window; use a unit size and shape similar to that used in other windows. Entry portico: The entry portico is weak. It does not have sufficient visual weight or interest to serve as the focal point for the main entrance. It is not very visible from the north or east. In addition, the lack of refinement in details, such as columns, detracts from the portico. Possible solutions: enlarge the portico to the west for greater visibility and an entrance "gate" effect; refine columns to better match downspouts, each other, and other vertical elements of the building. r Staff Report to Planning Commission/B.A.R. Foster Library, 6/15/94 Page 18 Cornice: The cornice helps the top of the building appear finished and anchored. However, the thickness of the cornice and the way it is attached to downspouts makes it appear out of proportion. The cornice also ends abruptly, which gives it the appearance of being "tacked -on" to the building. Possible solutions: reduce the thickness or layers of the cornice; strengthen other elements such as downspouts; wrap the edges back into the building; add columns or other vertical "grounding" element; extend the cornice across the length of the facade. Building lighting: Without an exterior lighting proposal, the building at night may appear drab, or even inhospitable. As this facility will be used and highly visible at night, an attractive lighting scheme should be integrated into the architectural design. For example, lighting could be used to highlight "medallions," columns or the cornice. 5. Miscellaneous Structures & Street Furniture. The project should include provisions for bike racks and trash receptacles. RECOMMENDATIONS: Staff recommends that the Foster Library proposal be approved with conditions. Refinements should be subject to final Board approval at a later hearing, or the Board could direct the applicant to submit refinements to staff for administrative approval.

This exceeds the 60 s.f. allowed by code. The sign will be located in landscaping at the street corner. While it appears classical in its shape and lettering style, there is no indication of materials or colors, or method of illumination. A wall sign is also proposed on the south wall of the entry. It appears to be approximately 9 s.f. in area. It is not clear from the application what materials, colors, or illumination will be used for the wall sign. CONCLUSIONS: The freestanding sign has an appropriate location, but its classical -style design is not consistent with the bold architecture of the revised building. The sign should be re- designed to incorporate elements similar to those found in the building. In the re- design, the sign area will need to be reduced to 60 s.f. to meet code. To evaluate the project's overall plan for signs, more information is needed regarding sign materials, colors and illumination. RECOMMENDATIONS: Proposed signs shall not exceed 60 s.f.; and plans shall be revised to ensure that sign design is consistent with the building's architectural theme, and shall include details on size, materials, colors and illumination.

(206) 431-3665 FINDINGS AND CONCLUSIONS BACKGROUND: Foster Library Revisions 8/22/94, Page 2 On June 23, 1994 the Board of Architectural Review (BAR) approved the Design Review application for the new 5,250- square foot Foster Library building, parking lot and landscaping at 4060 South 144th Street. The project was approved with 17 conditions related to the site plan/landscaping and the building design. The Board felt that the specific implementation of 8 of these conditions warranted further review by the Board. The applicant was directed to submit revised drawings which would implement 3 conditions related to the entry area, 4 conditions related to the building design, and 1 condition related to bike racks. The revised drawings were to be reviewed by the BAR at the 8/25/94 public meeting The 8 remaining issues for BAR review are discussed below. The BAR - imposed condition is shown in bold, followed by staff's evaluation of how the proposal addresses the BAR condition. FINDINGS: A. Main entry plaza and sitting wall 1. Entry area: "The entry area shall re- designed to complement the portico and better relate to the building and other site features." The applicant has revised the original entry area design and included better detailing (see Attachments A and B). The entry steps have a diagonal orientation which is repeated in the triangular- shaped planters, pavement scoring, handicapped ramp and cut -away ceiling of the entry portico (see Attachment F). 2. Sitting wall: "The sitting wall shall be refined to ensure an appealing and functional seating area, with an appropriate height and a cap wide enough for sitting." The applicant has revised the drawings to show a wide cap on the wall at the entry steps (see Attachment B). The applicant will include additional details of the sitting wall in building permit applications. Foster Library Revisions 8/22/94, Page 3 3. Entry plaza/walk: "The entry plaza/walk shall be re- designed to incorporate convenient barrier -free access, which is architecturally integrated with the entry plaza." A handicapped ramp has been incorporated into the main entry plaza (see Attachment B). The ramp repeats the strong diagonal theme used in the entry steps and the revised triangular- shaped planter. Sharp corners on the ramp were a Board concern. The applicant proposes to address this using a 6" radius on planter corners (see detail on Attachment B). B. Building design 4. Detailing of architectural elements: "The building design shall be revised to provide better detailing and internal consistency between architectural elements." The applicant has refined and further detailed several windows on the building (see Attachments C and D). The three windows on the west facade now match. The north window has a new shape which follows "notches" in the cornice. Its shape also relates to the main entrance window and cornice, which are similarly "notched." A new little window has been added to the north facade, with an L- shaped section of cornice above it. The medallions on the east facade have been framed with contrasting brick patterns. The medallions originally on other facades have been removed. 5. Entry portico: "The entry portico shall be re- designed to provide sufficient visual weight, architectural interest and detailing appropriate to an important public entrance." The entry portico is one of the most important features of the library. The original concern was that the portico design was not strong or refined enough for such an important element. The entire main entrance has since been re- designed (see Attachments C, D and E). The columns used in the portico now match each other (and those elsewhere). The cornice now has a "notch" in it, which relates to the shape of the window above the main door. • Foster Library Revisions 8/22/94, Page 4 6. Cornice: "The cornice shall be re- designed so that it is well- integrated with each facade, has an appropriate scale for the building, and has a balanced relationship with other architectural elements." The cornice is perhaps the most important architectural element in the library design. It provides virtually the only relief on the building facade. The cornice is not a typical cornice in that it does not extend around the entire building, or even the length of one facade. The edge of the cornice ends in one plane, rather than having the three tiers turn back into the building (see detail on Attachment D). The BAR condition was intended to address concerns that this important feature was out of proportion with other elements, was not well- integrated with the facade, and that it appeared to be "tacked on." Along with other architectural elements, the cornice has been revised (see Attachment D). On the north and west elevations, the cornice has been notched, to repeat new window shapes. A separate portion of cornice has been added to the north facade above a new, small window. The cornice previously incorporated downspouts as vertical elements (see Attachment C). The downspouts were revised so that the cornice is no longer attached to any vertical element. 7. Building lighting: "An architectural lighting plan shall be prepared which complements building architecture and details, with minimal impacts to adjacent residential areas." The applicant has proposed lighting on the south facade which will be incorporated into the cornice in a manner which highlights the medallions. C. Street furniture & site details 8. Bike rack: "Plans shall be revised to include bike racks; plans shall also include other street furniture..." Plans have been revised to include a bike rack at the main entrance. Foster Library Revisions 8/22/94, Page 5 CONCLUSIONS: A. Main entry plaza and sitting wall 1. Entry area: The strong diagonal orientation of the entry steps, ramp, planter and pavement, adds drama and interest to the main entrance. Each element is well - integrated with other entry features. 2. Sitting wall: The revised drawings, together with construction details to be submitted with building permit applications, will ensure that the sitting wall is appropriately detailed. 3. Entry plaza /walk: The handicapped ramp is well - integrated with the overall entry design. Potentially sharp corners on the ramp have been addressed by using a 6" radius on planter corners. The combined revisions noted above provide a main entrance which is visually strong and provides a memorable "procession" to the library from the street. The entrance will function well, and provide an appealing outdoor public space. Staff concludes that the applicant has met these BAR conditions. B. Building design 4. Detailing of architectural elements: Refinements have resulted in windows which are much better detailed, and which better relate to each other, and to other architectural elements. The concept of repeating "notching" in windows and cornice works well. The notches add architectural interest, and help integrate distinct features. However, the notches in the main entrance window do not have the same proportions as those in the cornice or in the north window. To strengthen the relationship intended by "notching," window panel shapes should be revised to be more compatible with existing proportions (see Attachment G). The little window on the north facade appears odd; it has no apparent relationship to anything else on the building. The added piece of cornice over this window exaggerates this incongruity. A window shape r Foster Library Revisions 8/22/94, Page 6 more similar to other windows, or extension of the cornice would help remedy this. The new framing around the medallions on the east facade better defines this element, and strengthens the medallions as a main feature and potential artwork. However, this interesting feature is not repeated elsewhere in the building. The result is that each building facade is more made more distinct from the other, when the facades already appear somewhat unrelated. Some medallions should be used on other facades so that the concept is integrated into the entire building. The concept of notches in the windows and cornice helps integrate the various architectural elements with each other and with the facade. Downspouts, columns, and medallions have been appropriately refined. With some minor revisions to the window shapes, and by repeating the medallions, as noted in RECOMMENDATIONS below, the proposal would meet the above BAR condition. 5. Entry portico: As noted above, the entire main entrance has been re- designed. The entry portico has not undergone major change, but has been refined and better integrated with other elements. Together, these revisions provide visual weight, architectural interest and detailing appropriate for the main entrance. 6. Cornice: The notches in the cornice (and windows shapes) on the north and west elevations help integrate the cornice with other architectural elements. However, staff is still concerned that the cornice may appear "tacked on to the facade. When the downspouts were redesigned to reduce their prominence, the cornice lost a vertical component which tended to "anchor" it. The cornice has no horizontal anchoring either, as segments of the cornice are not connected to each other. The combined effect is the appearance of a box- like awning over the windows. To some degree the cornice still appears to be "tacked on." This is especially true of the north facade, where the small window is topped by a separate portion of cornice. The revised cornice design does not seem to be the best solution to the BAR condition. Staff concludes that some refinements are still needed to 1..111 ILa, 00•E TMn<Ntp4 1CAO1D04T1 42nd AVENUE SOUTH eLA14T SCHEQL(I E I•nT o1.II1t1 CFCCULLEI lr MA.

SEPA Checklist submitted by Architects Reed Reinvald, dated December 3, 1993. b. Site plan, building elevations and landscape plan submitted December 3, 1993 by Architects Reed Reinvald, and revisions submitted May 16, 1994. c.

Geotechnical Report dated September 29, 1993 by Landau Associates, Inc. GG ; Co ralk 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431 -3670 • Fax (206) 431-3665 Foster Library MDNS 6/6/94, Page 2 DESCRIPTION OF THE PROPOSAL The applicant proposes to construct a new neighborhood library on a vacant 1.15 -acre site. The site is located in a single - family residential zone. The 5,520 square -foot library will include a covered entry leading to a lobby, a 70- person Multi- Purpose Room, staff offices and restrooms. The building will be 24' in height, with exterior of brick, stucco /Dryvit in earth tones, simulated stone, and painted metal accents. Site improvements will include a 35 -stall parking lot; landscaping, including large stature street trees and screening shrubs; biofiltration swale; and a curving entry walk with a seating wall. There will be parking lot lighting with down -ward directed fixtures. Street improvements are also planned, such as a 6' wide curbside sidewalk and street trees along 42nd Avenue South and South 144th Street. This new facility will replace the existing Foster Library located 1/2 block away on 42nd Avenue South. PRINCIPAL CHECKLIST ITEMS A. EARTH Other than a 2 -3' elevation gain from the street, the site is essentially flat. Construction debris from a demolished house has been previously removed, and an old well capped. No import or export of material to /from the site is expected. Based on this, no noticeable impacts are anticipated, and no mitigation is necessary. B. WATER There are no permanent surface water bodies on or near the site. Most of the site will be covered with impervious surfaces. Storm water runoff will be addressed using the existing system along South 144th, with the addition of an on -site biofiltration swale. The 6" water main on South 144th is sub- standard in size. C. PLANTS The site has previously been cleared and developed. Existing vegetation on site consists of mostly grasses and shrubs, and several large existing trees. Most of this vegetation will be replaced by new landscaping. A large, mature American elm is proposed to be retained, but it may not survive the impacts of construction and paving on root areas. Approximately 11 red alders along the northern Foster Library MDNS 6/6/94, Page 3 • edge of the site will be retained. The proposed landscape design also includes large stature trees within the site and along the streets. Measures to ensure survival of "retained" trees should be included in the plans. Other mitigative measures should be evaluated through Design Review by the Board of Architectural Review, as noted below. D. NOISE The new library will likely generate more noise than that typically associated with residential areas. Some mitigative measures are proposed. The building and main entrance is located as far as possible from residences. Where single family residences abut the west side of the site, there will be a 40' wide landscape buffer. Elsewhere, parking areas will be buffered by a 10 foot landscape area. Noise will also be reduced by the library's limited hours, which will typically be from 8:00 a.m. to 8:00 p.m. Other mitigative measures should be evaluated through the Conditional Use Permit process. E. LAND USE The proposed library will be located in a residential zone, with residences nearby. As a non - residential use in a residential area, the library proposal raises concerns regarding auto and pedestrian circulation, compatibility of building architecture with the neighborhood, screening and landscaping, lighting and signage effects, and its aesthetic and functional relationship to the high school. As the library will be located in a residential zone, it will require a Conditional Use Permit. Potential impacts of the proposal will be evaluated through this process. However, specific impacts and mitigative measures should be evaluated in more detail through Design Review by the Board of Architectural Review. Through Design Review, the site plan and design details can be refined to provide the best fit with the surrounding neighborhood. F. AESTHETICS The project is expected to have an effect on the aesthetic character of the neighborhood. Compatibility with the neighborhood would be best addressed through the required Conditional Use Permit and through the public Design Review process. ` Foster Library MDNS 6/6/94, Page 4 G. LIGHT AND GLARE The new library has the potential for light spillover and glare not typically found in a residential zone. Parking area lights and headlights from frequent traffic could affect adjacent residences. Such effects should be addressed using appropriately- designed lighting standards, landscape screening, and /or solid perimeter fencing. The effectiveness of these measures should be evaluated in greater detail through the Conditional Use Permit and Design Review processes. H. RECREATION The Tukwila Parks and Open Space Plan encourages the development of outdoor non -city recreation facilities. In addition, the Tukwila Comprehensive Plan encourages locating public recreational facilities within easy access to residents. Based on these policies, the new library should provide quality outdoor areas for the public. To ensure that the library proposal meets City policies for passive recreation, plans should be further evaluated through the Conditional Use Permit and Design Review processes. I. TRANSPORTATION /TRAFFIC It is estimated that the new library would generate approximately 250 (125 in, 125 out) vehicle trips to roads in the project area. Some of these vehicle trips will be additional over traffic generated by the existing library. Vehicles will use two driveways into the site, one of which will be new. The existing four -way stop at the intersection of 144th Street and 42nd Avenue will remain. The right -of -way along South 144th Street is substandard. In accordance with Tukwila Ordinance No. 1616, the property owner will be required to dedicate an additional 10 feet of right -of -way. Sidewalks are included in the proposal. Based on this, no significant traffic impacts are anticipated, and no mitigation measures are necessary. MITIGATED CONDITIONS OF APPROVAL Issuance of a Mitigated Determination of Non - Significance is appropriate, as the environmental review indicates no probability of significant adverse environmental impacts from the proposal. Below are the conditions of approval: • • .,, Foster Library IONS 6/6/94, Page 5 1. Water main: To address the sub - standard 6" water main on South 144th, the property owner shall sign a Water System No Protest Agreement to participate in the future upgrade of the main. 2. Trees: All trees proposed for retention shall be adequately protected during construction. Any of these trees lost within 3 years from the time of construction completion shall be replaced. 3. Design Review: To more specifically address potential impacts and to ensure compatibility with the surrounding neighborhood, the library design shall be further refined through the Conditional Use Permit and Design Review processes. The proposal shall include for Board of Architectural review the following revisions: a. To reduce light spillover into adjacent residential lots, the west and north perimeter of the site shall have a solid decorative fence and /or opaque landscape screening. b. Given Tukwila policies regarding outdoor recreation, the proposal shall provide quality outdoor areas for the public. Prep by: Ann Siegenthaler Contrul No. Epic File No. ENVIRONMENTAL CHECKLIST A.

SEM. REVIEW 1. The SEPA checklist will be resubmitted with signature (this was an oversight on our behalf). 2. All reference to a future expansion will be removed from the drawings. 3. Existing trees on site will be verified and indicated on the site plans. 4. Site dearing: it is our understanding that all construction debris has been removed from the site and the existing well has been capped according to Ecology regulation 173 -160 WAC (Minimum Standards for Construction and Maintenance of Wells). 5. The 36" storm water detention pipe will be revised to include 54" diameter manholes on the construction documents. QF NON- SIGNIFICANC 1. The KCLS will dedicate an additional 10 feet of right -of -way along South 144th Street for compliance with Tukwila Ordinance No. 1616 (the owner will contact the City for appropriate forms). 2. The KCLS will sign a Water System No-Protest Agreement for participation in the future upgrade of the substandard 6" water main on South 144th Street. 3.

Due to the anticipated impact on the project schedule, we would like to schedule this meeting as soon as possible. cc. Kay Johnson - KCLS Doug Blair - KCLS William Reed - ARR Stephen Wong - AA David McNeil - JGM David Dorothy - BCG David Kisser - Tukwila Library Board • 03. 04. 94 08 : 26AM *ARCH REED REINVALD C„ DESIGN REVIEW Site Plan; RECEIVED MAR tj 4 1994 CUivifv?UM s Y DEVELOPMENT P 0 3 page - 2/8 /1. The entrance 'forecourt' along South 144th Street will be enlarged to the North (towards the building) to take into account your concerns. We would like to note that due to the main lobby for the library being 300 square feet, we do not want to create an overwhelming entrance sequence that dwarfs the impact of actually entering the library. 2. The loading and service areas are not functionally incompatible with the main entrance since the loading /unloading and servicing of the building happens when the library is closed and so no conflict between auto, pedestrian or bike traffic will occur. The trash and recycling areas will be adequately screened per BAR Design Guidelines and will be indicated on the building elevations. ./3. We will review widening the West sidewalk to address your concerns. We have designed aot €= wide walk to take into consideration the bumper overhang of cars to allow for a minimum clearance of 5� rte' feet while maintaining the appropriate scale for the library (see previous 'forecourt' item above). /4. We shall revise the site design to include alternate paving materials across both driveways. 15. We shall revise the site plan to show the book drop locations. 6. Street improvements: a) The plans will be revised to reflect the additional 10' of dedicated right -of -way. b) The plans as submitted incorporated a separated sidewalk along South 144th Street with a minimum 6' wide sidewalk and a minimum 5' wide planting strip with street trees. The planting strip will be irrigated. A 6' wide curbside sidewalk was indicated along 42nd Avenue South as required. 7. Parking: f a) The parking proposed is based on the traffic studies for libraries of this size within the KCLS with an additional parking calculation based on more critical criteria using occupancy uses within the library. We have found that planning departments typically base the parking calculation for public libraries on a gross square footage calculation (e.g. 300 gross square feet per stall). We shall revise our plans to show maximum build -out of parking at this stage (which will provide 33 parking spaces). If the Planning Commission determines the parking requirement based on an assembly occupancy, we will have to reduce the size of the public meeting room t t the naximum capacity of the site for parking. l -°€ cup`/ ix eer b) The minimum full -size parking space is to be 8.5 feet wide with minimum compact space to be 8 feet wide. c) The design as submitted provided for 26 full-size parking spaces (no compact spaces at first phase). With full build -out of 33 parking spaces, 10 spaces will be compact size (for maximum of 30% of total need). 8. The most important criteria in the development of the library design has been the unique location of the proposed site. The challenge has been to remain consistent both with the varying scale and quality of the single and multi- family residential uses to the North, South, and West, and the monumental scale and plan of the New Foster High School to the East. To address your concerns on this subject, we present the following ideas and issues explored in the designing of the submitted project: 03. 04. 94 08: 2 AM *ARCH REED REINVALD MAR 0 4 1994 History: f F V E L.O P ME. In our research of the site and the surrounding community of Foster, we have developed a greater understanding of the unique history of the area. From the Duwamish villages of longhouses (simple horizontal struccures clustered on the White River), to the legacy of Joseph Foster and his establishment of the first settler community (a learned man who came to the territory in 1853), the rich farmland which provided for the development of a strong community identity and the creation of civic amenities (both the Foster and Tukwila Libraries), and the tradition of community pride and activism that continues to this day. While we have not tried to tell a story of the area using a narrative design approach, we have tried to incorporate many conceptual references into the planning and detailing of the library. These references include the following: 2 +Land Forms - the use of berms and swales on a reasonably flat site reflecting the local prehistoric sites of the native Duwamish people. +Simple Rectangular Form for the Main Reading Room Massing - like the Duwamish longhouse and the agricultural structures imprinted on the memory from the past. +Neoclassical Elements - the settlement by immigrants from Europe and their bringing of Western values and cultural identity. +Civic Siting - the placement of the library on the site within the civic context of the street intersection and the main entrance off the civic boulevard of South 144th Street P 0 4 page - 3/8 Neighborhood Context: We believe there is no specific "established neighborhood character" to this area. Adjacent to the proposed site is a single -story rambler house and a large multi-story apartment building to the North, a 1 1/2 story cottage house and a single -story double -wide mobile home to the West, a single -story rambler and a vacant lot to the south (with a large multi -story apartment building to the Southwest and a 1 1/2 story cottage house at the street intersection to the Southeast), and the monumental New Foster High School to the East. We do not believe the proposed site is accurately described as set within "a low- density, primarily residential, development in a Northwest suburban community." The setting is actually a neighborhood in transition with a combination of single family, multi- family, and public structures heavily influenced by major and minor arterial routes and the varying commercial atmosphere along Highway 99 (located two blocks to the West). New Foster High School: We have extensively studied the design of the New Foster High School (including meeting with the design architects Dean Willows and Chris Johnson of BJSS. We received a copy of the building construction documents for our reference during the design of the Foster Library). We concur with your assessment that "an imitation of the high school design is not appropriate for this small library" and that "some relationship between elements is desirable." The following comparisons clarify our design strategies: Windows and Fenestration: In particular we studied the window fenestration of the high school's street facades. The rhythmic relationship and balance of these windows are reflected in the east facade of the proposed library opposite the school. The high school window openings are grouped in a collegiate style reflecting the modular aspect of the classrooms behind (and the size and scale of those rooms). At the Library, regularly spaced 'eyebrow' openings relate to the rhythmic window layout of the high school. The library's windows similarly explain the main interior space within, they are located above the bookshelves on the interior of the space). The high school has commercial windows with aluminum extrusions The library will use wood clad windows which give greater character appeal both from within and outside the library. Ornate window moldings around the exterior of the window reflect a more domestic treatment of the fenestration giving a greater play of shadow, shade lines and texture in contrast to the high school which has no moldings or lintels. O rte. 04. 94 08: 2 6 AM * ARCH REED RE I N V A D 1994 P05 COivIMUNI PY DE\fELCDPMENT page -4/8 Columns and Entrance: The high school has columns located at the plaza pavilions suggesting entrance to the facility (of which there is no entrance). Similarly, a porticoed colonnade is the major design element at the entrance to the proposed library. The high school uses columns created from precast concrete cylinders, disks, and blocks appropriate to the scale of the facility. The library will have columns accurately proportioned to the building mass and their pedestrian location. While the high school has the benefit of size and mass to allow for lack of detail in the exterior elevations, the library (at 4% the size of the high school) must develop sufficient detail to maintain quality within its greatly reduced scale. Other issues relating to the Foster High School: +The proposed location of the library at the street intersection corner provides a Western edge to the monumental high school entrance plaza (this issue was specifically reviewed with the high school design architects). While the high school is able to abandon the street corner due to it's overwhelming scale, the library must hold the street edge and comer because of its residential scale. 4-The location of pedestrian routes support existing pedestrian travel pathways and minimize pedestrian /vehicle conflicts (pedestrian safety has been an important concern in the site development due to its proximity to the high school and the busy street intersection). +The stepped massing of the library presents the its largest elevation to the high school while reducing the building's scale toward the bordering houses to the North and West. +The proposed library will feature a similar landscape palette as the high school's, enhanced to create the garden quality of the library landscape design. Puilding Elements: We do not concur with your statement that the use of "Greco-Roman elements" are "typically found in more urban, monumental structures" and so are not appropriate for this site. The classical language in architecture has been used extensively in residential architecture since first introduced into the Veneto by Palladio in c.1550 (the Villa Capra in Vicenzia was a summer house set in the farmlands of northern Italy). In the United States, it was popularized by the residential design of Thomas Jefferson for his home in Monticello. In the centuries that followed, classical treatment of suburban and rural houses has undergone untold degrees of ornamentation from the austere proportion of the Georgian period, the outlandishness of the Victorians, and the refinement into the Queen Anne and the Arts and Crafts movements. The development of a classically inspired library in a suburban setting is probably best referenced by looking at the work FL H. Richardson in 1880's New England. While its true that Neoclassical architecture is found on a monumental scale within more urban settings, its use and interpretation on a domestic scale is as appropriate to this site as a large Greek revival bungalow built in 1920's. Since this is the 1990's, not the 1880's, we have made our interpretation of classical elements as deemed appropriate to their location, reference, and use. We have developed a building vocabulary which allows the elements to be different relating to their function and the use implied by their location (e.g. - the windows for the reading mom are different from the windows for the staff room though they share common referential elements - as these windows are on separate massing elements of the building, they are never seen in the same plane). We do not agree that the design for the library uses "A different idiom ... for other library features, such as the windows and cornice detailing, which creates disharmony in the facade." We firmly believe that our design for the New Foster Library is compatible with the high school, reflects its neighborhood context, maintains internal architectural consistency, and includes a multiplicity of architectural, historical, and cultural references which we hope will provide for continuing exploration and understanding by both the patrons of the library and the citizens of Tukwila. O3. 04. G4 08 : 26AM >I< ARCH REED RE I N V A L D 'i 1994 P 0 6 page - 5/8 9. Materials and Colors: a) We agree that the building materials selected should "be consistent with (the) anticipated life of the structure" as outline by the Tukwila Municipal Code 18.60.050. This is why we have chosen the field exterior material as a cement stucco covered with an acrylic resin finish. This type of exterior finishing on wood framed construction will provide the library system with a low maintenance /long lasting /good looking building. The use of the acrylic resin finish will allow for detailed moldings and comices not readily constructible in other materials (this type of exterior finish material was used on the Tacoma Library Main Branch in downtown Tacoma and on the Federal Way Regional Library in suburban Federal Way).The use of a cement stucco base material over cement board provides for a durable method of construction to take the anticipated abuse from library patrons (this type of exterior finish is superior to brick /block due to its ability to resist graffiti and allow for expedient and cost effective repair /reapplication). You reference the Foster High School as an example of appropriate materials; yet, over 75% of the exterior material on this building is stucco with an acrylic resin finish over gypsum sheathing or rigid insulation. We are providing an exterior finish equal to this system even though the high school is required to be a much higher type of construction for compliance with the Uniform Building Code (Type II -1 HR versus Type V Nonrated for the library). We would also like to note that the detailing of the veneer brick elevations on the high school have only two dimensional patterns with no window moldings or articulated cornice. An equivalent quality of execution in the treatment of the library would result in a cold institutional appearance due to the reduced scale and would be contradictory to the neighboring properties (some which have stucco exteriors -none of which have brick). zic /2e1- A b) This revel of detailed information is not normally developed during the schematic design phase. d i:,ais „4 We will continue development and submit at the earliest opportunity. >a306J c) Building elevations, site plan, and landscape plan will be revised to show the emergency exits. d) This level of detailed information is not normally developed during the schematic design phase. We will continue development and submit at the earliest opportunity. 10. Portico: a) The portico is designed to engage the building and allow the building corners to penetrate into the portico while allowing the portico elements to be highlighted against the mass of the building elevations. Since the portico is always approached obliquely, there is no axial view down the portico West to East (only God sees buildings in true elevation). The portico is properly aligned to maintain consistency in the handling of detail and building elements. b) The curve is designed to be subtle and the column lines do not interfere with the line of pedestrian circulation. c) The design vocabulary of the portico relates specifically to the library's context. 11. Cornices and Base: The building cornices and base are designed to relate harmoniously and proportionally with the building. The design for the cornice is not "unresolved" or "unfinished ". Further detail will be submitted as design is further developed. 12. Windows: a) The window bays are designed both from the outside in and the inside out. Their depth has been determined for both the exterior modulation and the maintaining of consistency in detailing, while providing the maximum interior alcove allowed by functional constraints. b) The windows on the east elevation are specifically designed to be different from the other windows! Please refer to previous item C 8. c) The skylight will not be seen above the roof parapet and so will not be visible on the exterior elevation drawings. A roof plan was not required on the application checklist and so will be provided as soon as available. d) Window locations will be shown on the site plan as requested (though no mention o: this requirement is contained in the application checklist). X03. 04. 94 08: 26AM *ARCH REED REINVALD jvd,,k199 P 0 7 page - 6/8 13. Mechanical units will be screened. A roof plan was not required on the application checklist and so will be provided as soon as available. 14. Site lighting is indicated on the schematic site plan. Detailed lighting design has not been developed yet and will be provided as soon as available. 15. A public information and display area is already programmed into the lobby of the library (please refer to Floor Plan drawing SDA -2). Landscape 16. Outdoor public spaces a) We have made every effort to include "quality outdoor areas for the public which are safe, inviting and interesting, and free from auto /bike /ped conflicts " as encouraged by the City of Tukwila and the Tukwila Tomorrow Citizens Committee. As a responsible developers, KCLS also canvassed the opinion of the neighborhood at three public meetings to discuss the library project. At these meetings, there was overwhelming concern expressed by local residents against any passive outdoor recreation areas interior to the site due to their concern, and experience with, activities by youths contrary to the health and safety of the neighborhood; thus, we have developed the outdoor spaces adjacent to both South 144th Street and 42nd Avenue South to allow 100% visibility exterior to the library site. b) KCLS has a set procedure for the commissioning, installation and maintenance of public art which can be submitted to the City of Tukwila Arts Commission for their review. In past projects, public art is commissioned prior to the development of appropriate settings and we recommend a similar procedure be adopted here to assure artwork that has meaning relative to its context. c) Proposed site furniture is indicated on the schematic site plan. Detailed design of proposals were not a requirement of the application checklist and so will be provided as soon as available. 17. We will revise the site plan to include maximizing the parking available on site (refer to previous item C 7 - Parking), thus no rear lawn will now exist. The landscape design will be revised to include perimeter screening as required by the Tukwila Municipal Code. 18. Bioswale: The bioswale was sized in accordance with current King County Washington Surface Water Design Manual as adopted by the City of Tukwila. Since we could only get 180 feet of swale (instead of 200 feet), the bottom of the swale was widened to provide equivalent treatment area. The side slopes of the swale are 3 :1 (per City of Tukwila and King County criteria) with the slopes above the swale at 2:1 to accomrnodate the grading of the parking lot and the existing grades to the West. A bioswale is proposed in conjunction with underground storage as required by the City of Tukwila Storm Drainage Standards. We shall review the possibility of shifting the building and parking to the East to allow for "thoughtful grading and attractive landscaping." %Ak will also indicate the proposed educational component iu bell 'chided in the bioswale eonotr ction. 19. Landscape treatment a) The curve in the forecourt planter, like the portico, is inked to be subtle to give it greater meaning. Please refer to previous items C 1, C 8 & C 10. b) The preliminary plant list indicated several choices of trees for this area. Both species of trees, the Flowering Pear and the Flowering Cherry, have attractive columnar varieties. The columnar shape of the trees would continue the "rhythm" of the entry columns and provide a visual extension and closure for the portico from the library entrance. 20. Perimeter landscaping: we will revise and add perimeter landscaping to comply with City of Tukwila Guidelines. • 03. 04. G4 08 : 26AB& *ARCH REED REINVALD ': ,r1AR E' i A 1994 P 0 8 21. The landscaping around the Southeast building corner is designed to open up to.the street intersection to allow views of the bay window and activities being held within. The landscaping is designed to accentuate the berm up to the window to heighten the importance of this city corner. Their is no window bay at the Northeast corner. 22. The landscaping adjacent to the alcove on the North elevation will be revised due to the shifting of the building to the North (see previous items MDNS 1 & C 1). 23. The "foundation" shrubs are shown 6' -7 from the building to help accent the slope of the proposed grading up to the building (see previous item C 21). This will also provide access around the building for ease of maintenance. 24. The choice of River Birch trees along the edge of the parking lot will be reviewed. We believe that if properly place, and perhaps pulled further back from the edge of the paving, the aphid honey dew drip will not be a problem. 25. Schematic or design development drawings do not generally show all of the specific plant choices, but give a range of possibilities. This allows the plan to be developed further as other criteria is revealed during the final stages of design. A detailed plant list with specific .plant choices will be provided on the final planting plan. 26. Perimeter fencing: Plans will be revised to show extent of proposed fence (total perimeter boundary on the West and North of the site). Fence is proposed to be a constructed of cedar and be approximately 6' high. Detailed design has not been developed yet and will be provided as soon as available. 27. Grading: A critical component of the preliminary grading plan has been to balance the cut and fill calculations on site. With anticipated delay in start of construction, we will review additional cost due to anticipated import of structural fill and landscaping potential of additional native soil generated on site. 28. Lighting: Site lighting is indicated on the schematic site plan. Detailed lighting design has not been developed yet and will be provided as soon as available. 29. The location for above ground meters /vaults have yet to be determined. Detail drawings were not required on the application checklist and will be provided as soon as available. 30. All landscape areas will be irrigated, including street planting strips, and plans will be submitted for approval with building permit application as required. 31. Location of parking lot from the West property line will be revised (see previous item C 18). Street h niture and SiteMe ail s: 32. Proposed site furniture is indicated on the schematic site plan. Detailed design of proposals were not a requirement of the application checklist and so will be provided as soon as available. Slimes: 33. Site sign design has not been developed yet and will be provided as soon as available. • 34. Detail drawings were not required on the application checklist and will be provided as soon as available. City of Tukwila John W. Rants, Mayor Department of Community Development Rick Beeler, Director February 14, 1994 Mr. David Boe ARCHITECTS REED REINVALD 201 I Street Tacoma, WA 98403 RE: New Foster Library, Tukwila Dear Mr. Boe: The Department of Community Development (DCD) has completed its preliminary review of the SEPA Environmental checklist, Conditional Use Permit application and Design Review application for the above project. Prior to a DCD recommendation of approval for these applications, revisions are necessary. The required revisions for each application are listed below. A. SEPA REVIEW The following corrections must be made to the application: 1. SEPA checklist needs to be signed. 2. SEPA and other-approvals are for improvements shown on plans, and do not include any future improvements. On "Project Information" on plans, remove all reference to future expansion. Alternatively, you may revise project scope and drawings for approval of maximum site build - out. 3. Show existing trees on plan (approx. size & species); show trees to be retained, if any. 4. Site clearing: Has existing construction debris been removed? Has well been capped? If not, address both issues in checklist. 5. The 36" storm water detention pipe requires 54" (vs.. 48") manholes. It is expected that the project will merit a Mitigated Determination of Non - Significance (MDNS). The following items are the preliminary conditions of the MDNS: 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431-3670 • Fax (206) 431-3665 Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 2 1. Right -of -way on 144th is substandard. In accordance with Tukwila Ordinance No. 1616, the property owner must dedicate an additional 10 feet of right -of -way. The City will provide the necessary forms. 2. The 6" water main on South 144th has been identified as substandard to serve anticipated future development in the project vicinity. Therefore, the property owner must sign a Water System No- Protest agreement to participate in the future upgrade of the main. 3. Design Review: As a non - residential use in a residential area, the proposed library could have adverse aesthetic impacts on the neighborhood. A public facility of this nature raises concerns regarding auto and pedestrian circulation, compatibility of building architecture with the neighborhood, screening and landscaping, lighting effects, and its aesthetic and functional relationship to the high school. To address these issues, design review by the Board of Architectural Review is required. 4. Outdoor public spaces: The Tukwila Parks and Open Space Plan encourages the development of outdoor non -city recreation facilities. In addition, the Tukwila Comprehensive Plan encourages locating public recreational facilities within easy ----access-to-residents. - -Based on these policies, the new- library should provide quality outdoor areas for the public. The "sitting wall" at main entrance partly satisfies this goal. Plans must be revised to show appropriate outdoor seating and gathering areas (See also discussions under "Landscape Plan" and "Site Plan. ") B. CONDITIONAL USE PERMIT -- See Design Review, below C. DESIGN REVIEW Before DCD can recommend approval of the project to the Board of Architectural Review, the current proposal needs considerable refinement. I recognize that the plans submitted with your applications were preliminary, and believe that most of these revisions your team would have addressed in due course. To clarify our expectations as to an acceptable level of quality in Tukwila's new library, the required revisions are noted below. Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 3 Site plan: 1. The front "forecourt" should provide a grand entrance and appropriate processional experience to the main entry. As designed, the forecourt does not do this. It is too small, does not complement the portico, and does not provide a pleasant gathering space. It needs to be re- designed. Consider widening front steps to allow seating, extending the curved portion out to form a seating wall above the street, and using a shape which contributes to the overall design. • 2. The loading and service area at main entrance is aesthetically and functionally .incompatible with main entrance. Auto, pedestrian and bike traffic will converge in this location, with probable conflicts. Revise plans to relocate these functions. Trash and recycling area should be adequately screened, per BAR design. guidelines; show this on building elevation drawings. 3. The front (west) walk is a high - volume area for pedestrians and bikes. Front lawn area (northwest corner . of building) may become trampled by southbound pedestrians taking short but to entrance. Walkways at these areas should be widened.to 10 feet, and /or re- designed into paved mini - plaza. 4. Due to high pedestrian, bike and auto use, driveways should be designed to minimize ped /bike /auto conflicts. Revise plan to include alternate paving materials across both driveways. 5. To clarify how the main entrance functions, show book drop location on site plan. 6. Street improvements: a) Revise plans to reflect dedicated 10' right -of- way as noted in SEPA review comments. b) Street improvements are required as part of the project. Show separated sidewalks along South 144th Street; with minimum 6' wide sidewalk and minimum 5' wide planting •strip with street trees. Planting strip must be irrigated. •A 6' wide •curbside sidewalk is required along 42nd Avenue South. Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 4 7. Parking: a) Planning Commission will determine required number of stalls. However, it does not appear that 20 visitor stalls will accommodate peak use, esp. for 70- person Multi- Purpose Room. Assuming 1.5 persons /car, minimum parking need would be 52+ (46 + 6 staff + other users). Provide additional documentation to demonstrate how peak use will be accommodated. On- street parking does not count toward satisfying minimum. b) Project info on drawings says parking stalls are 9x19 feet. Plan shows 8x19 feet; minimum for standard is 8.5' width; minimum for compact 8' width. Revise plans accordingly. Show number of compact stalls. Maximum allowed is 30% of total need. Building design: 8. An important consideration of the Board of. Architectural Review will be the library's relationship to its surroundings. To meet the Board criteria, the library "should be consistent with the established neighborhood - - - - -- - .character "- -- ( TMC - -- 18.60.050 -) - -- As currently designed, the library does not meet this requirement. Two key connections are missing: the library's relationship to 1) Foster High School, and 2) the larger neighborhood context. Foster High School provides the backdrop for the library. While an imitation of the high school design is not appropriate for this small library, some relationship between elements is desirable. For example, window types or materials might be repeated in the library. More importantly, the new library should reflect its setting in a low - density, primarily residential, development in a Northwest suburban community. However, the library uses Greco -Roman elements which are typically found in more urban, monumental structures. A different idiom is .used for other library features, such as the windows and cornice detailing, which creates disharmony in the facade. . Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 5 These elements should be refined to 1) be compatible with the high school 2) reflect the library's neighborhood context;. and 3) provide internal consistency between architectural elements. 9. Materials and Colors: a) Quality materials are a critical component in the creation of a highly visible, long - lived, community facility. This was true for Foster High School. It is even more important for a smaller -scale building like the new library, where the relationship with the user is more intimate and details are more important. Use of simulated stone and sculpted simulated stone raises concerns about durability and close -up appearance of materials. In contrast, a combination of split and smooth -faced brick is long -lived and can be used to create architectural interest in the building base, reveals, and other details. The Board review criteria require that "building components...shall be consistent with anticipated life of the structure" (TMC 18.60.050). Wood frame construction with dryvit and simulated stone do not provide an acceptable level_of quality for the new library:- masonry or equivalent is highly recommended. b) Building elevations contain many unidentified lines which may /may not indicate different materials or planes. Submit drawing of building details with materials notes (e.g. column cover, column base, doors, building and portico cornices, roof, window frames, depth of reveals, etc.) c) Emergency exits (2) are not shown on south and west building elevations. Revise elevations to show exits which are appropriately designed and integrated with the building's overall architecture, site plan and landscaping plan. d) Materials board, showing proposed materials and colors for the building, is required. Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 6 10. Portico: a) Portico is not centered on entrance, and west corner of wall juts into line of travel. Revise to appropriate alignment. b) Curve in portico is so subtle that it looks like an error in alignment; the slight offset of columns makes columns appear to interfere with line of travel. Portico needs to be re- designed. c) As noted above, the design vocabulary used in the portico should relate to the library's context. 11. Cornices and Base: The roof line and base of the building should have sufficient visual "weight" to give the building the appearance of being anchored. The library cornice has a sharp, unresolved curve and appears unfinished. A close look at historical references shows cornices built up in layers to create depth and weight through detail and a solid cap. The cornice should be re- designed accordingly. Reconsider also the detailing on the cornice, which does not relate to other architectural elements. The base of the building also lacks depth and should_be_..enlarged_.in- proportion - with -- the. -re - - designed cornice. 12. Windows: a) Window bays greatly enhance building interior, exterior and the site. Deeper bays would create an inviting alcove inside the library, and give more definition /modulation to the building exterior. To achieve this, extend the two 2- foot deep window bays to a minimum of 5 feet. b) Individual windows added to east elevation are not in proper proportion with other windows. Their' individual cornices appear as tacked -on "eyebrows," rather than a setting for windows. These windows need to be re- designed with the same unit size and shape used in the other windows. Individual windows could repeat the idea of a panel extending to ground level, or be grouped in "bays" of two or four. Mr. D. Boe, Architects. Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 7 c) Original proposal showed skylight over lobby. If skylight is part of proposal, show on building elevations (if visible), and roof plan (as required in Item #12). Windows enhance the "processional" experience of visitors entering the site, especially where the formal entry is removed. Windows also enhance nighttime appeal of the site and building. To clarify this, show window areas on site plan. 13. Mechanical units must be screened. Submit roof plan, showing where rooftop mechanical unit(s) will be located and how it will be screened. 14. Lighting: Lighting should be designed to complement building architecture and details. Revise elevations to show appropriate exterior lighting. (See also Lighting, under "Landscape Plan. ") 15. Citizens have suggested a bulletin board /display case at main entry. This could add to the neighborhood's "ownership" of the library. Evaluate the feasibility of this (cost, vandalism risk, etc.); if appropriate, designate an area on building elevations. Landscape Plan: 16. Outdoor public spaces: a) As noted under SEPA review, Tukwila policies encourage the development of outdoor recreation areas. The design of a Conditional Use must demonstrate consistency with City policies. In addition, the Tukwila Tomorrow citizens committee envisions the area at 144th and 42nd Avenue South as the eastern "anchor" or focal point for a "neighborhood center" (TTC, 11/18/93). These focal points will be special areas in terms of their uses, pedestrian amenities and provision of public open spaces. In a community facility like the library, which will serve users of various ages and backgrounds, passive outdoor areas are especially important. The library will be used in all seasons, throughout the week, during daylight and evening hours. Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 8 Revise plans to include quality outdoor areas for the public which are safe, inviting and interesting, and free from auto /bike /ped conflicts. Include seating areas, covered waiting areas, and spaces designed to accommodate future public artwork. b) Along with outdoor spaces, quality public buildings take advantage of opportunities to incorporate public artwork. Public . art can include paving inlays, . sculpture which provides seating, or murals. The Foster Library has several location options: at driveways, main entrance, corner of 42nd and 144th, the north facade, etc. However, no attempts have been made to address this in the library design. Revise landscape and site plans to include interesting outdoor settings which could incorporate future public art. c) Outdoor areas for pedestrians should utilize quality materials and include appropriate furnishings, e.g. special paving for main entrance "court," comfortable seating. Submit drawing showing such details (see comments under "Street Furniture & Site Details "). 17 -Rear lawn_ area .reserved .- for . -- future - parking- . -is -- ignored--- in- _ - - - - -- landscape and site plans. This is very large, visible area which needs to be addressed. Revise landscape plan to include plantings, perimeter screening, sculptured earth or other treatment appropriate for a community facility. 18. Bioswale: Bioswale as shown appears to be overly large. With sides having steep 40% slope, bioswale is very unattractive ditch. Revise landscape and grading plans to show thoughtful grading and attractive landscaping. Submit section detail of revised bioswale with plantings. Alternatively, replace bioswale with equivalent underground detention, and revise landscape plan accordingly. 19. Landscape treatment at main entrance drive and forecourt is very important in "setting the stage" for experiencing the library. Proposed landscaping here does not take advantage of opportunities: Cu sub cur pla dr b) Bos doe cu not the rh the bet (e. com "ga Mr. D.

Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 10 25. Planting schedule lists several plant species per symbol. Clarify on planting schedule which plant species will be used where (e.g. whether street trees will be Raywood ash, red maple or both). 26. Perimeter fencing: Plan shows fencing in some areas but not others. Revise plan to show any proposed fencing; include detail and material. For a community building surrounded by residential uses, fencing should be of quality material and construction. Chain link is not acceptable. 27. Grading: Grading does not appear to be used creatively in the landscape, especially at north entrance, south entrance and rear lawn area. Are there opportunities to incorporate berms, or otherwise use grading to complement landscaping? 28. Lighting: Well- designed exterior lighting is essential for a safe and inviting library. Lighting should be designed to 'provide safe, attractive, pedestrian -scale walkways, and to accent landscaping. Revise plans to show appropriate site lighting; include details of standards and fixtures. 29. Show location of any above - ground meters /vaults. These must be screened with landscaping or a decorative wall. -30. Irrigation of all areas, including street planting strips, is required. Irrigation should be designed to conserve water; plans must be submitted for approval with building permits. 31: Landscaping plan shows parking lot at 25' from west property line; site plan shows this dimension is 30 feet. Show correct dimension in plans; make any necessary revisions in planting materials. Street Furniture and Site Details: 32.

Show locations of all permanent wall and freestanding signs on site plan, building elevations. Mr. D. Boe, Architects Reed Reinvald Foster Library Preliminary Review, 2/14/94 Page 11 34. Submit detail drawings with dimensioned sign elevations and materials notes. Include materials and colors on materials board. The above comments are based on DCD's preliminary review of the project applications. Depending upon how these revisions are resolved in the design, additional comments or revisions may be necessary. However, I have confidence in your creative ideas and expertise; beyond the above refinements, no significant design changes are anticipated. I hope these comments will assist you in the next stage of'design development, where the preliminary drawings are refined to meet Board of Architectural Review standards. I would like to meet with you to discuss our comments. After you have reviewed the items listed above, please call me at 431 -3670 to schedule an. appointment. Sincerel Siegen haler cc: L.

Allen Doerschel, CT (t 2 :1 VL ^3 Date: May 19,1993 From: Doug Blair Re: s er Library ablic Meeting —of-April-14, 1993 The meeting was attended by about 25 citizens including representatives of the school district, city council, city administration and the Tukwila Library Board. The comments listed below are not edited or organized in any way other than the order in which they occurred during the meeting. 1. The library should be compatible with and compliment the school. This point was raised by both a citizen and by a school district representative. 2. Concern was expressed as to whether the number of parking spaces required by code would be adequate given the size `c the meeting room. Posifi e sired parking at the school was recommended. 3. A drop off on 42nd was suggested. 4. A children's play area at the northwest corner of the site was suggested. Any park should be a passive park according to city representatives. Don Williams should be contacted at the city regarding any park proposals. 5. Concern about the high level of night activity now was expressed by a neighbor who was not supportive of the park idea. 6. The idea of having the building at the corner with the parking behind was considered desirable. 7. Neighbor to the west wants a barrier (fence) to cut down on traffic across his property. KCLS anticipated a fence being required. 8. Materials for sidewalks and stairs should consider skateboarders and rollerbladers. 9. Two city council members present and the school district representative all supported the idea of an electronic reader board sign. KCLS cited concerns about the cost of running and maintaining the sign and aesthetic concerns about such a sign becoming the dominant feature of the site rather than the library itself. 10. A "user friendly" design with easy access to the children's area was requested. 11. Tukwila Art Commission is interested in the possibility of placing art on the site perhaps in an outdoor area. Foster Community Meeting Notes page 2 12. Concern was expressed for serving and welcoming a multilingual patronage. Multilingual signs or .artist d_g signed building components were suggested as possible means. 13. A covered outdoor area for children's programs or for outdoor eating was suggested. 14. A covered outdoor book drop with minimal walk from parking was requested. A car drop off was first requested but the physical impracticality was explained. 15. A covered portico for dropping people off was requested. 16. Bicycle racks were requested. KCLS noted that they are provided at all libraries. 17. A small play area for children was requested. 18. Natural lighting in the library is desired. 19. Changing stations in the rest room were requested. KCLS noted that they are provided in all new buildings. 20. Avoid right angles and sharp edges in design. 21. Kent library feels too barnlike, not cozy. Foster should have a cozy feel. 22. Desire to separate children's area from adult reading areas. 23. Compliment Foster High School outside but keep cozy, intimate feeling inside. 24. Use wood rather than metal where possible to keep a warm feeling. 25. Consider multicultural nature of area. School district has 26 languages spoken at home in student population. The collection in the library should reflect this diversity. 26. Tutoring rooms desired with terminals, P.C., or multimedia machines. KCLS noted that such rooms are now provided in all libraries. 27. If an outside children's area is provided there needs to be a way to view outside for safety. 28. The city is open to operating a passive park if one is provided on the site. 29. A fold up stage or risers for the multipurpose room was requested. 30. Seven day a week open hours were requested. Provisions for the STAR Center were requested.
