lighting will match the design of existing lighting and will illuminate the site and adjacent sidewalks without <br />causing excess brightness or spillover lighting to the Green River. <br />CONCLUSIONS <br />DESIGN REVIEW CRITERIA <br />1.Relationship of Structure to Site <br />Minor changes to the transition from the fueling facility to the streetscape are proposed with this project, and include <br />adding shrubs to fill in the gaps in the existing hedge within the north and east landscape perimeter areas. Pedestrian <br />movement is currently accommodated along sidewalks on the north and east perimeter of the project site, and there <br />are no changes proposed to these areas. The addition of fueling dispensers and expansion of vehicle queuing area for <br />the fueling facility will improve vehicular circulation on the project site. The addition of a new curbed landscape <br />area will separate the Costco Optical facility employee parking area from the fueling facility to help keep pedestrians <br />out of the fueling facility area where vehicle maneuvering and idling enginescharacteristic of a gas station do not <br />create an amenable pedestrian environment. The height of the canopy extension will match the height of the existing <br />canopy, and at 17’ 6” in height is in scale with the roof height of surrounding buildings. The scale of the structure is <br />consistent with surrounding warehouse retail and industrial buildings. <br /> <br />2.Relationship of Structure and Site to Adjoining Area <br />The canopy extension will use the same materials and will be of the same design as the existing canopy area. <br />Concrete block proposed for the fueling canopy is consistent with the concrete block used on the Costco Optical <br />facility, and the combination of concrete block and metal are consistent with materials used in neighboring <br />developments including the Costco warehouse to the north and the Home Depot to the south. Changes proposed to <br />circulation, including removal of employee parking areas from the vehicle queuing area of the fueling facility, will <br />help reduce potential conflicts between cars entering the fueling facility and pedestrians and slower-moving vehicles <br />within the employee parking area. <br />3.Landscaping and Site Treatment <br />Demolition of multiple parking lot landscape islands and the addition of new landscape area will result in a total loss <br />of 76 square feet of landscape area. The new landscape area will include more trees than currently exist in landscape <br />areas that will be demolished. New landscape areasinclude trees,shrubs and groundcover andwill help promote an <br />inviting entry into the fueling facility. Parking has been reconfigured so that a total of 20 parking spaces will be <br />located adjacent to the new landscape areas. The new landscape areas range from approximately five to six feet in <br />width. Since there is no room to locate plantings back from the curb to prevent damage from parked cars, staff <br />recommends a condition of approval to add wheelstops to these 20 parking spaces to prevent damage to the plantings <br />in the new landscaped areas. Irrigation is required in landscape planting areas. An irrigation plan was not submitted <br />with design review application materials, but the applicant has stated that irrigation is planned to be provided in the <br />new landscape area. As a condition of approval, an irrigation plan shall be submitted with the building permit for the <br />canopy extension. Additionally, the landscape plan submitted for the building permit shall include the following <br />notes and specifications to help plantings within the new landscape area prosper: <br />a. Add a note that all wire and twine and the top 2/3 of burlap are to be removed from B& B plants before <br />planting. <br />b.Add specifications for plant quality per ANSLA standards, including for B&B trees. <br />c.The new planting strip needs to have good soil preparation to ensure that soils are decompacted and <br />loosened to at least 18 inches and that resulting planting soils have at least 10% organic material in them (via <br />the addition of compost like Cedar Grove or equivalent that is tilled in to the soil). Notes should be added to <br />the plan about soil preparation. <br />d.Provide specifications for mulch and its application. <br />e.Add planting notes – top of root ball even with soil surface, loosen root ball and straighten or prune any <br />circling roots in container-grown plants before planting, etc. <br />JR Page 9 of 11 08/14/2013 <br />H:\Design Review\Costco Gas Station\SR_L13-038 Costco Fueiling Facility Expansion.docx <br />15 <br /> <br />
