rockery wall. Retaining walls over four feet need to meet setback requirements unless <br />the setbacks are waived per TMC 18.50.150. The proposed retaining walls meet the <br />setback waiver because the site is on the low side of the wall and not visible to adjoining <br />properties. <br />D. Pedestrian - Oriented Features <br />The windows and canopies on the ground floor are provided. The plaza also wraps <br />around the corner of the building and helps links the building with the public realm. <br />E. Mechanical Equipment <br />The HVAC units servicing the building will be located on the roof and will be fully <br />screened from view on all sides by the building parapets. Also the building is equipped <br />with internal roof drains therefore no downspouts or scuppers will be visible. <br />III. LANDSCAPE DESIGN <br />A. Landscape Design <br />Five feet of Type I landscaping that includes one tree per 30 feet is required along <br />Tukwila International Boulevard. A minimum of 10 sq. ft. of interior landscape area is <br />required for each parking stall over 20. The retaining wall is proposed to be screened by <br />Boston Ivy that is planting at the base and cascading Cotoneaster that is planted at the <br />top of the wall. Smaller accent trees along with planters are proposed in the plaza area. <br />One of the existing street trees is proposed to be removed to accommodate the <br />driveway. <br />The landscaping along the north wall is proposed to help soften the facade. However <br />Tukwila Police has suggested including some shrubs with thorns for crime prevention. <br />B. Planting Design <br />Interesting mix of plants is proposed to add variety and interest to the planting plan. The <br />choice of plants in the rain garden is appropriate for visual interest and function. There <br />may be an opportunity to replace the bench with a planter. Additionally, irrigation is <br />required and the building permit submittal shall include an irrigation plan. Also, the plant <br />quality shall meet the standards in the ANLA American Standard for Nursery Stock. <br />Page 7 of 11 <br />11 <br />
