The Process I application is hereby approved per the findings and . conclusions noted below. FINDINGS OF FACT 1. The applicant proposes to install a one-story 1,792 square -foot prefabricated portable classroom at Nautilus Elementary School. 2. The zoning for the subject property is Single -Family Residential (RS 9.6). The existing school is an allowed use in the RS 9.6 zone per Federal Way Revised Code (FWRC) 19.200.090, "Schools." 3. The portable will be of standard construction. Roofing material will be a black/dark gray asphalt shingle. Siding will be plywood surfaced with hardboard, and of a color designed to blend with the main school building. Foundation skirting will be painted to match the siding. Window and building corner trim will be clear cedar with a coloring to complement the siding. 4. The proposed improvement is shown to be setback more than 50 feet from all property lines and will be approximately 14-feet in height, in compliance with FWRC 19.200.090. 5. According to the applicant, the building will provide classroom space to alleviate current shortages and assist the district in meeting statewide standards for student to teacher ratios. The project is not related to any additional students or staff added to the school; rather it is to reduce crowding. Therefore, no additional parking is required per FWRC 19.200.090. 6. Three trees will be removed within the project area and the applicant plans to plant three 6-8 foot deodar cedar trees near the portable per FWRC 19.120.130(t)(b). These trees will provide landscape screening of the northern fagade, which contains blank wall space in excess of 240 square feet (FWRC 19.125.040[22)). 7. Nonconformance is not triggered due to the small size of the building per FWRC 19.30.090(1)(a). 8. A building permit and fire alarm system are required for the project. 9. For the associated concurrency evaluation (File 17-102222-CN) a Capacity Reserve Certificate was issued on May 18, 2017. Mr. Sean M. Comfort Page 2 of 2 June 12, 2017 CONCLUSIONS OF LAW 1.

The addition of the building will provide important classroom space and alleviate current shortages, to help the District meet statewide standards for student to teacher ratios. This project is not related to any additional students or staff that will be added to the school; rather, this is strictly to reduce crowding that has occurred. The parcel number is 0521049005 and the site is approximately 9.99 Acres in size. The subject property is zoned Single -Family High Density Residential (RS9.6), and that zoning district permits school uses. The placement of the portable will not alter the existing use of the site, which is a public school. The proposed portable will add additional instructional space. The portable will have electricity, but no water or sewer service, and the portable will not be used for classroom space for science labs, art studios, or other instructional types that would require running water. The new double classroom portable will be located west of the existing school and will be 1,792 square feet each in size, single story, and not fire sprinklered. The portable will have metal stairs and a ramp that will connect to the existing school via a paved path. No new parking stalls will be added to the campus. SEPA The proposed improvements are exempt from environmental review, pursuant to FWRC 14.15.030 (C). A letter of SEPA Lead Agency / SEPA Exemption is enclosed. Architectural Design The portable will be of standard construction. The roofing material will be asphalt shingle, of a black -to - dark gray color. Siding will be durable plywood surfaced with hardboard, with 8-inch grooves, and of a color designed to blend with and complement the color of the Nautilus K-8 School's main building. The skirting surrounding the portable's foundation will be plywood painted to match the siding. Trim, around windows and at the building corners, will be clear cedar with a coloring to complement the siding. Site Development Description The project proposes 1,982 square feet of new plus replaced impervious area. The proposed portable will be placed on existing paved and grassy surfaces. The project proposes approximately 4,500 square feet of land disturbing activity. The project does not contain and is not adjacent to any flood areas or Critical Drainage areas. The new double portable classroom will include four downspout extensions. All of the proposed downspout extensions will convey stormwater via outfalls. There will be two outfalls emptying onto a rock pad, flowing out to a pervious surface on the site. Compliance with Development Regulations The project complies with the required setbacks (50-foot front, rear, and side from Residential Areas) and does not exceed the maximum building height of 30 feet. The project will not result in the site exceeding the maximum lot coverage of 75 percent. Cc 2 fiance with Clearin y, G rad i ng. and Tree and Vegetation Retention Re Q uirements Three large mature trees will be removed in the area where the new portable will be placed. In order to comply with the City's Tree Replacement requirements, the project will include the replanting of three threes which will be of a comparable species, and which feature a mature canopy (Deodar Cedar, Cedrus deodara, 6-8' minimum height). The planted trees will need irrigation for establishment and then will be drought tolerant. The site plans indicate the planned location of the plantings, as City staff has indicated that the replanted trees may be located anywhere on the site. (Note: While there was no tree count performed on the site, we viewed Google Earth imagery and concluded that tree replacement would be required due existing tree density.) No added Students, no_new Instructors As stated above, the project will not result in any new instructors or students. This is a project to provide more space and alleviate current classroom crowding. Community Design Guidelines The project is required to align with the Community Design Guidelines as detailed in FWRC 19.115.020. During a pre -application assessment, Federal Way Planning Staff listed four items that are related to the proposal. We have listed the four items below, and indicated how the project complies with each guideline: a. "Overall design continuity with the existing improvements by using similar elements such as materials, colors, and textures." The portable will be of standard construction and will be designed to blend with and complement the color of the Nautilus K-8 School's main building. b. "Roof design shall utilize forms and materials that avoid the general appearance of a 'flat' roof." The roofing will be asphalt shingle, of a black -to -dark gray color. The roof pitch will be 1/6. c. Provide delineated pedestrian connections to the main building(s). The portable will have metal stairs and a ramp that will connect to the existing school via a paved path. d. "Building facades longer than 60 feet that are visible either from a right-of-way or a residential zone or use must provide two of four specific design treatments: (1) facade modulation, (2) landscape screening, (3) canopy or arcade, and (4) pedestrian plaza. Please note that if three facade treatment options are incorporated, dimensional flexibility can be provided." The portable will not be in view from the closest public right-of-way or from the surrounding residential uses. Mature trees of significant size and age (deciduous and non- deciduous) and low-level shrubs and other vegetation provide a dense screening buffer which block views of the future portable location. (See Figure 1 and Figure 2) Figure 1: Aerial Photo and Vie w Screening Sketch Figure 2. Viewfrom NearestRight of Way - Annotated Landscave Screeninp, Reauirements City staff advised that landscaping would be required (pursuant to FWRC 19.125.040(22)) to screen any building walls greater than 240 square feet or greater in area, that were not otherwise interrupted by architectural features (windows, doors, etc.). The front face of the portable will exceed 240 square feet, but the fa4ade will include fenestration: two doors and six windows. On the rear face of the portable there will be minimal fenestration. However, as previously demonstrated, the building will not be viewable from surrounding properties and is screened by landscaping along the site perimeter. (See Figure 1 and Figure 2). Therefore, this project will comply with the landscape screening requirements. 19i�VEIVEV May 10, 2017 MAY 12 2017 CITY OF FEDER WAY COMMIJ1�"DEl1ELOPM� Kevin Peterson City of Federal Way Department of Development Services 33325 8r" Ave S Federal Way, WA 98003 Er, PPIC- 's Project: Nautilus Portable Project, Our File No. 2160955.10 Subject: Storm Drainage Report Lap'wsap, Arc ;!i? s Dear Kevin: t arr;rrs:'Y."r 8;n—T;s Nautilus K-8 school is located at 1000 South 2891h Street, Federal Way, Washington, on Parcel No. 0521049005.

Base connections are a pinned condition. III Each frame is connected together with landing or ramp frames and planking to distribute dead and live loads to the frames. Railing is added to the frame assembly. c) Landing Platforms are attached to buildings with Lag -bolts or SDS Screws. d) Basic Dead Load is 5 psf for frame, ramp & landing surfaces. 2 psf is added for railing. WELCOME RAMP CALCS-IBC 2012 & 2015 Page 2 e) A 300 lb. lateral load is used in the design to simulate seismic, wind and pedestrian lateral loading for each frame (2 frames per unit, 600# per assembly). This results in an effective Design Cs for a 30-foot ramp and 5x10 platform of 0.5 and a design wind load of 30 psf without consideration for stress duration. Seismic and wind loads do not govern lateral loading for standard configurations. For those configurations having landings attached a building on one side longer than 40', soil anchors shall be installed at the rate of (1) anchor for each length of landing 40' longer than 40'. For those configurations having landings attached to a building on two sides longer than 60', soil anchors shall be installed at the rate of (1) anchor for each length of landing 60' longer than 60'.
