The applications are approved subject to conditions. Testimony Alex Morganroth, City of Renton Senior Planner, summarized the proposal. Laura Brent, Brent Planning Solutions, LLC, spoke on behalf of the Applicant. She noted that the Applicant had engaged in public outreach prior to the hearing. Matt Feldmeyer, RSD Executive Director of Capital Planning and Construction, noted that the nearest school other than Hazen is Honeydew Elementary located to the southwest about ¾ mile. He confirmed that the traffic demand management plan required of the project will include event planning communications. He also identified that the Hazen High School lot can be used for event overflow parking but that the proposed 82 parking spots should be sufficient for after school events. Randal Chun, neighbor, inquired about speed control on Duvall Avenue. He identified that there’s a lot of speeding on Duvall with kids racing cars. He felt that Duvall Avenue needs dips and speed bumps to control speeding to avoid hazards to the school children. Mr. Chun also noted that Duvall 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 2 2 Avenue had a litter problem. Brianne Bannwarth, Development Engineering Manager, noted that the City is working on speed mitigation measures for Duvall Avenue, which will include a landscaped medium. Todd McBryan, the Applicant’s traffic consultant, noted that a new school zone will be placed along the project site on Duvall Avenue. He also identified that crossing guards would be placed at the project site when children are walking to and from school and that a traffic signal will be installed at 10th and Duvall as well. Mr. Morganroth noted that one cause of the litter problem was the vacant lots comprising the school site, prompting people to throw their garbage into the lots as they travel down Duvall. In closing, Ms. Brent identified that school districts work at being good neighbors and would address garbage if that was a continuing problem. Exhibits The August 3, 2021 Staff Report Exhibits 1-39 identified at Section B of the staff report were admitted into the record during the hearing. In addition, the following exhibits were admitted during the hearing. Exhibit 30 Google Earth Exhibit 31 City of Renton COR Maps Exhibit 32 City of Renton Power Point Findings of Fact Procedural: 1. Applicant. The Applicant is Renton School District No. 403. 2. Hearing. The Examiner held a virtual hearing on the subject application on August 3, 2021 at 11:00 am via a Zoom hearing hosted by the Renton City Clerk’s Office, Zoom Meeting ID No. 854 6631 7755. Substantive: 3. Project Description. The Applicant has applied for site plan, conditional use permit and modification approval to construct a 77,000 square foot elementary school at 1058 Chelan Avenue NE. The project site includes 11 parcels approximately 11.08 acres in size with street frontage along both Chelan Ave NE and Duvall Ave NE. In addition to the 77,000 square foot elementary school building, there would be an outdoor classroom area, multipurpose playfield, hard/soft play areas, and a covered play area. A surface lot would provide parking for 82 vehicles and a school bus load/unload area would provide capacity for eight full size busses and two special education buses. Passenger vehicle access to the subject property is proposed at the south end of the site with one full access driveway along the Duvall Ave NE frontage and one exit only access on Chelan Ave NE. School bus access would be provided via two driveways along Duvall Ave NE. The Applicant would construct street frontage improvements along both the Duvall Ave NE and Chelan Ave NE frontages. The Applicant has requested two code modifications with the application related to onsite parking and street frontage improvements. Studies submitted with the application include critical areas report, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 3 3 drainage report, geotechnical report, arborist report, and traffic impact analysis. The proposed modifications are to street and parking standards. For both, the Applicant is requesting modifications to exceed maximum standards. For the street standards, the Applicant is requesting a modification to street frontage standards between the proposed on-site bus lane exit and the southeast property corner along Duvall Street to add a nine (9’) foot wide queuing lane, which will also include a dedicated bicycle lane within. For the parking standards, City parking standards allow for a maximum of 60 regular parking spaces and 10 bus spaces. The Applicant is proposing a total of 82 regular spaces, 8 full-sized and two small school bus spaces. 4. Adequacy of Infrastructure/Public Services. The project will be served by adequate infrastructure and public services as follows: A. Water and Sewer Service. The proposal will be served by adequate water and sewer. Water and sewer service will be provided by the City of Renton. There is an existing 16-inch water main in Duvall Ave NE and an 8-inch sewer main in Chelan Ave NE. B. Fire and Police. The proposal will be served by adequate police and fire service. Police and Fire Prevention staff indicated that sufficient resources exist to furnish services to the proposed development if the Applicant provides Code required improvements and fees. To provide for adequate fire flow, the proposal is required to install a 10-inch looped water main around the new school building and traversing the project site. In addition, the installation of three (3) new fire hydrants on site is required including one within 150 feet of the building and two within 300 feet of the building. The installation of signs indicating “Fire Lane ONLY” are required to be installed at both ends of the fire land transitions to the grass paving areas (Exhibit 27). C. Drainage. Adequate drainage facilities are proposed. The Applicant submitted a Preliminary Drainage Plan and Technical Information Report (TIR), dated January 8, 2021 (Exhibit 16). The development is subject to Full Drainage Review in accordance with the 2017 Renton Surface Water Design Manual (RSWDM). All nine core requirements and the six special requirements have been discussed in the Technical Information Report. The project is split into 3 distinct drainage basins (North, South and Wetland) and will provide flow control and water quality for each drainage basin in accordance to the 2017 RSWDM. There is a 12-inch stormwater main in Chelan Ave NE southwest of the subject property frontage located along the west side of the existing roadway. The stormwater main drains to a private water quality facility located on two adjacent parcels. The Applicant will be required to ensure that the stormwater pond and associated appurtenances and property are protected in the final storm drainage design. In addition, there is another 12-inch stormwater main (R-3386) in Chelan Pl NE south of the subject property located along the west side of the existing roadway. The stormwater main drains to a private water quality facility located on the 102305-9485 and 9486 parcels. The Applicant will be required to 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 4 4 ensure that the stormwater pond and associated appurtenances and property are protected in the final storm drainage design. D. Parks/Open Space. As conditioned, the proposal provides for adequate and appropriate parks and open space. Open space is provided on the site via multiple elements including the multi-use playfield, the interior courtyard between the two classroom wings, and the outdoor classroom area. Most open space is programmed for passive recreation to provide a qui et learning environment for students, with the exception of the multi-use playfield. The area adjacent to the wetlands buffer at the rear of the site behind the school building provides a quiet focal point for students to use for reading, studying, or meditating and is a central feature of the site. City regulations do not require any park land dedication or park impact fees for the project. E. Transportation. The proposal provides for adequate and appropriate transportation facilities. Passenger vehicle access to the site is proposed via two access points including a driveway along the Duvall Ave NE frontage allowing full access and one exit-only access on Chelan Ave NE. School bus access would be provided via two driveways along Duvall Ave NE connected to an associated bus lane used for pick up and drop off of students. The Applicant would construct the required street frontage improvements along both the Duvall Ave NE and Chelan Ave NE frontages. The proposal provides a safe and efficient circulation pattern for both vehicles and pedestrians within the site. The parking lot is located on the south side of the site with a single access point off of Duvall Ave NE. Locating the parking area on one end of the property helps to preserve the majority of the site for pedestrian oriented activities and decreases the potential for pedestrian and vehicular conflicts. The surface parking areas provide clear pedestrian pathways close to building entries and minimize pedestrian crossing drive aisles. In addition, the design of the parking lot allow for the queuing of parents in vehicles when dropping off or pick up students. After entering the off of Duvall Ave NE, vehicles will wind through the aisles in the lot waiting their turn to access one of the seventeen (17) marked drop off stalls adjacent to the plaza and front door. After dropping their student off, parents can choose to exit via the Duvall Ave NE access point, or the exit only access point onto Chelan Ave NE. The proposal locates bus load/unload along Duvall Ave NE in a dedicated on-site bus lane with pedestrian off-load that reduces the potential pedestrian conflicts. Buses will enter the bus lane via a right-in only entrance on the north side of the site, drop off or pick up students in one of the ten (10) bus stalls, and exit the site onto Duvall Ave NE via an right turn-only egress point. As currently designed, pedestrians would cross the two bus lane driveways via painted cross walks. In order to better delineate the pedestrian crossings and provide a clearer visual cue for bus drivers entering and exiting the site, and be consistent with 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 5 5 driveway standards, staff recommends as a condition of approval the Applicant submit a revised utility plan with the civil construction permit application that extends the Duvall Ave NE sidewalk across both bus lane driveways removing the painted crosswalks. The revised plan shall be reviewed and approved by the Current Planning Project Manager prior to permit issuance. Once on the interior portion of the site, regardless of entry point, a series of concrete pedestrian pathways weaves through the programmed exterior spaces and allows teachers and students to safely navigate the site via walking or biking without the potential for a vehicular conflict. The proposal also provides for desirable transitions and linkages between uses, streets, walkways and adjacent properties. A variety of vehicular and pedestrian linkages are proposed to ensure the site is connected to the surrounding area and is accessible to all users regardless of travel method. The Applicant has proposed an internal pedestrian pathway system that once completed, will provide connections between the parking lot, main school building, outdoor classroom area, and hard surface play area. The internal pathways, ranging in width between five (5’) and ten (10’) feet continue to the north, south, and eastern peripheries of the property where they connect with public sidewalks in the Duvall Ave NE and Chelan Ave NE right-of-way. An additional pathway incorporated into the surface parking lot connects to Chelan Pl NE, a public street to the south of the site with no sidewalks. The surface parking lot with 82 vehicle stalls and associated student drop-off area can be accessed via a driveway off of Duvall Ave NE near the southeast corner of the property. An exit-only access point is proposed on the north side of the property via Chelan Ave NE which will provide a secondary egress option for parents leaving the student drop- off zone and will help relieve congestion at the primary access point off of Duvall Ave NE. Overall, pedestrian and vehicular connections between the site and surrounding area are efficient while remaining respectful of the potential impacts to neighboring uses through the use of controlled access points (i.e. exit-only driveway). Loading and delivery areas are concentrated on the eastern end of the building along the bus drop-off and pick-up lane. Except for the beginning and end of the day when students are walking to and from the front doors to the bus loading area, pedestrian traffic is expected to be limited. As long as deliveries are scheduled outside of the two times of day where buses utilize the lane, the potential for conflicts is anticipated to be minimal. Congestion and other transportation impacts were assessed in the Applicant’s Transportation Technical Report prepared by Heffron Transportation, dated January 14, 2021. The report found that the proposal would not generate traffic that exceeded the City’s level of service standards except for traffic generated at the intersection of NE 10 th and Duvall Ave NE. Duvall Ave NE is classified as a principal arterial. According to the traffic report the level of service standard for arterial intersections is C. The morning traffic generated by the elementary school would lower level of service for the NE 10th/Duvall intersection from LOS A to LOS E. To mitigate against this impact the SEPA mitigation measures require that the intersection to be signalized. The traffic report concludes that 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 6 6 signalization will reduce the drop in LOS from E to C, which is compliant with the City’s LOS C standard for that intersection. The traffic report recommends several other mitigation measures designed to mitigate all other potential traffic impacts, including construction traffic impacts and impacts caused by large school events. Most of those recommendations have been adopted as SEPA mitigation measures. Impacts to system wide transportation network will be mitigated via imposition of traffic impact fees pursuant to the terms of the City’s transportation impact fee ordinance. The proposal has also passed the City’s Traffic Concurrency Test per RMC 4-6-070.D (Exhibit 23), which is another congestion standard adopted by the City. The City’s concurrency standard is based upon a test of the citywide Transportation Plan, consideration of growth levels included in the LOS-tested Transportation Plan, and future payment of appropriate Transportation Impact Fees. F. Transit and Bicycles. The proposal provides for adequate and appropriate transit and bicycle facilities. Per RMC 4-4-080F.11 the number of bicycle parking spaces shall be at least equal to 10 percent of the number of required off-street vehicle parking spaces. The Applicant is proposing 12 uncovered bicycle parking spaces, exceeding the minimum requirement, and proposes to locate the parking near the building’s main entry in the public plaza. King County Metro Transit (Metro) provides bus service in the vicinity of the project site with the closest stops, served by Route 240, located about 0.3-mile north of the site at the NE Sunset Boulevard / Duvall Avenue NE intersection. There are also stops, served by Route 105, located about 0.4-mile to the west of the site at the NE 10th Street / Union Avenue NE intersection. G. Parking. The proposal provides for adequate and appropriate parking. As noted in Finding of Fact No. 3, the Applicant is asking for a parking modification to exceed the City’s maximum of parking permitted by the RMC. The Applicant’s transportation report identifies a peak demand of 74 parking spaces. The proposal will provide 82 parking spaces onsite and new on-street parking along N. 3rd Street. Bus loading and unloading is proposed along within the bus lane accessible via an entrance and exist off of Duvall Ave NE. Additionally, for special events, more parking capacity is available within the drop-off/pick-up queue, bus lane area, and offsite parking can be provided at Hazen Highschool across the road if required. In addition to the proposed stormwater facilities, impacts resulting from parking impervious surfaces are minimized by breaking up the surface with a series of landscape islands that allow for infiltration during rain events. Approximately nineteen (19) trees are also to be located within the interior or perimeter of the parking and will help provide storm water uptake. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 7 7 5. Adverse Impacts. There are no significant adverse impacts associated with the project. Adequate infrastructure serves the site as determined in Finding of Fact No. 4. A State Environmental Policy Act Mitigated Determination of Non-significance was issued for the project on June 21, 2021 with several mitigation measures designed to eliminate significant adverse impacts. See Ex. 11. Impacts are more specifically addressed as follows: A. Structure Placement and Scale. As conditioned, the structure placement and scale are not expected to create undue adverse impact on the adjacent residences and is designed to protect privacy and reduce noise for on- and off-site occupants and to maintain compatibility with existing development and surrounding uses. The design and positioning of the two-story building on the site is respectful of the neighboring residential-scaled properties through the use of step-down roof forms and open spaces/landscaping between the building and the adjacent residential areas. The building would be sited near the center of the site’s north/south axis and would be located over 300 feet away from the nearest residential structure. The protected wetlands and associated buffer to the north of the building create a heavily vegetated buffer area that provides a significant level of visual screening between the proposed building and the existing single- family neighborhood west of the site. In addition to the purposeful siting of the building near the center of the site, the structure itself uses a variety of articulating and modulating effects on the various facades in order break up the perceived scale of a single, large building on the site. High quality materials, large areas of glazing, and overhangs/canopies all contribute to the goal of ensuring the school building integrates into the surrounding residential neighborhood and does not result in an overscale structure or overconcentration of development on any portion of the site. B. Views. No obstruction of existing views of natural features are anticipated, including view corridors to shorelines or Mt. Rainier. The vacant property currently has limited views of natural features due to the presence of unmaintained vegetation. The most two most prominent natural features on the site, a stand of significant and landmark trees near the proposed outdoor classroom area and the Category III wetlands on the west side of the site, will have more visibility after project completion due to the removal of invasive vegetation and creation passive recreation areas on the site. No other views would be impacted as a result of the project. C. Noise, light and glare. The proposal will not create any significant noise, light or glare impacts. The Applicant prepared a noise study to assess compliance with noise standards. The study showed that the proposal will comply with the City’s maximum allowed noise levels. The greatest regular source of significant noise will be a “chiller” that apparently provides air conditioning. At the closest residence, the chiller will produce a maximum noise level of 44 dBA. Adopted noise level limits at this location are 57 dBA daytime and 47 nighttime levels. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 8 8 The study also assessed the impacts of other noise sources, including bus traffic and an emergency generator. All noise levels were found to be within adopted City standards. The emergency generator is exempt from maximum noise levels, but would only be used in times of emergency or for maintenance. The school building, parking lot, and grounds will be lit after dusk each evening for safety purposes. RMC 4-4-075 provides standards that limit light trespass such as parking lot pole height limitations of 25-feet with cut-off type luminaire and building lights directed onto itself or the ground immediately abutting it. A condition of approval requires that a lighting and photometric plan be submitted for review with the building permit application. Standards for design review and compliance with exterior lighting standards will be reviewed with the building permit submittal. D. Screening. Unattractive site features will be adequately screened from view. The service yard area with generator and chiller is attached to the building and are integrated into the design of the building through use of similar façade and roof materials (Exhibit 6). The enclosure utilizes a light blend brick veneer with regular metal gate that is not visible from the public ROW and is approximately 8 feet tall. The Applicant did not provide details of roof or surface mounted equipment and/or screening identified for such equipment with the land use application. Therefore, a condition of approval requires that the Applicant be required submit a surface mounted utility plan that includes cross-section details with the civil construction permit application. The Applicant shall work with franchise utilities to ensure, as practical, utility boxes are located out of public ROW view, active common open spaces, and they shall not displace required landscaping areas. The plan shall provide and identify screening measures consistent with the overall design of the development. In addition, a condition of approval requires that the Applicant be required to submit a rooftop equipment exhibit with the elevation plans associated with the building permit application. E. Fencing and Retaining Walls. Proposed fencing will not create any significant impacts. As conditioned, all proposed fencing is lower than eight feet and does not block landscaping or serve as a traffic hazard. The Applicant has proposed black, coated vinyl chain-link fencing varying in height between four (4’) feet and six (6’) feet around the perimeter of the site. The Applicant has also proposed a small section of six (6’) foot tall cedar fencing on the south side of the site to partially close off the Chelan Pl NE ROW from the property. The cedar fencing matches the existing fencing on the residential properties along Chelan PL NE. Cedar split rail fencing is also proposed along the perimeter of the Wetland C buffer on the west side of the site as required by RMC 4-3-050. While all fencing appears to comply with the maximum fence height requirements for nonresidential uses, some fencing appears to stand in front of required landscaping, specifically the sight-obscuring landscaping around the southern 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 9 9 portion of the site between the parking lot and Duvall Ave NE and Chelan Ave NE. Per RMC 4-4-040.E.1, fencing shall not be located within or in front of any required landscaping. Therefore, a condition of approval that the Applicant revise the fence location and place the fence behind the required landscaping along all property lines on the detailed landscaping plan to be submitted with the civil construction permit application. F. Natural Features. The proposal will not adversely affect any natural features. The area of the site where the school and associated improvements would be constructed is predominantly flat and therefore grading is expected to be average for a development of this size. The exception to this is the removal of approximately 6 to 8 inches of organic material on some portions of the site where moisture content is too high to support new buildings and therefore would be replaced by structural fill. The wetlands area on the west side of the site would be protected in perpetuity and would not be permanently impacted by construction. To site the structure in manner that would protect the higher-quality wetlands (Wetland C), the Applicant has proposed filling the lower-quality wetlands on the east side of the site, to be mitigated for by purchasing credits from the Springbrook Creek Wetlands Mitigation Bank. G. Landscaping. Aesthetic, noise, light and privacy impacts will be minimized by existing and proposed landscaping. The Applicant has submitted a conceptual landscape plan, admitted as Exhibit 3. Landscaping is primarily concentrated around the proposed building, parking lot, and two street frontages. Perimeter landscaping is also proposed and required within the parking areas. Due to the proposal of a non-residential use within a residential zoning district, a partial or fully sight-obscuring landscape strip of 10-feet or 15-feet, respectively, is required along all shared property lines. Staff have evaluated the proposed landscaping and found that, with recommended conditions, the proposed landscaping will meet the City’s landscaping standards. Those standards are adopted by this decision. Significantly, staff has determined that providing an effective screen within the landscape buffer to the south of the parking will help limit the noise and visual impacts of the parking lot on the adjacent residences and is therefore very important. To ensure compliance with code, one of the staff recommended conditions adopted by this decision requires the Applicant to increase the number and mature species size of trees within the buffer through the utilization of larger species like standard Western red cedar and Douglas firs. The greatest sources of noise and activity for the project site will likely be the parking lot on the south end and the play area on the east side of the project area. The extensive amount of landscaping proposed for the south of the parking lot coupled with the wetland protection area to the north, as well as the extensive perimeter landscaping will serve to minimize aesthetic, noise, light and privacy impacts to surrounding residences. H. Critical Areas. The proposal will not create significant adverse impacts to critical areas. Wetlands and steep slopes are located on the property. Staff have determined that the 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 10 10 proposal adequately protects critical areas as required by the City’s critical area regulations with staff recommended conditions of approval, all of which are adopted by this Decision. Impacts and mitigation are more specifically detailed as follows: 1. Steep Slopes. The City’s COR mapping database identifies the property to contain Sensitive Slopes (15-40%), which are primarily concentrated on the western portion of the site near the wetlands area. The Applicant submitted an Updated Subsurface Exploration and Geotechnical Engineering Report (Exhibit 17), prepared by Associated Earth Sciences, Inc, dated December 22, 2020 with the project application. In the report, the consultant acknowledges the presence of sensitive slopes on the site. The exploration utilized data from 20 borings completed by advancing hollow-stem auger tools with a track-mounted drill rig. Samples were obtained at 2.5 to 5-foot depth intervals. Subsurface conditions were found to encounter native materials consisting of medium dense grading to very dense lodgment till sediments, and ten (10) of the borings found surficial fill to depths of up to 7 feet below the existing ground surface. Results varied at the other boring locations and included the discovery of Vashon recessional outwash, stratified sediments, and organic topsoil at shallow depths. The findings of the exploration were identified to be consistent with the Geologic Map of the Renton Quadrangle which indicates the site is underlain at shallow depths by Vashon lodgment till. Groundwater was not encountered during exploration activities, but is expected to be present during the winter rainy season as it becomes trapped or ‘perched’ on top of the Vashon lodgment till. The potential for liquefaction was analyzed and was determined to be unlikely. The report provides standard recommendations for erosion control, but due to the lack of identified hazard, does not make specific recommendations for earth preparation outside of the standard control measures. The report also provides specific recommendations related to site preparation, building foundations, stormwater infrastructure design, and pavement design. Specifically, the report concludes that grading completed in a manner consistent with the recommendations in the report would not result in increased risk of slope instability on or offsite. A condition of approval requires that construction comply with the recommendations found in the submitted Updated Subsurface Exploration and Geotechnical Engineering Report (Exhibit 17), prepared by Associated Earth Sciences, Inc, dated December 22, 2020, and future addenda. 2. Wetlands. A Critical Area Report prepared by The Watershed Company, dated March 31, 2021 (Exhibit 20) was submitted with the application and identified the presence of two wetlands on the site, identified as Wetlands B and Wetlands C in the report. The Watershed report concludes that as mitigated, the proposal will not create any net loss of wetland function. Wetland B, located near the front (east) of the site along Duvall Ave NE, was classified as a Category IV depressional wetlands and a total on-site area of approximately 0.28 acres. According to the consultant, direct impacts to Wetland B cannot be mitigated on- site due to a lack of suitable areas on-site that would still allow for the building size and 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 11 11 amenities required for an elementary school. The Applicant proposed removal of the wetland. In conjunction with the purchase of credits from a City wetland mitigation bank, the Applicant has proposed enhancing portions of the Wetland C buffer that have experienced degradation and lack native tree and shrub cover. The Applicant proposes wetland replacement in the mitigation bank at a ratio of 0.70:1 as required for Category IV wetlands. Wetland C, located near the back (west) of the site, was classified as a Category III depressional wetlands with a total on-site area of approximately 0.48 acre. According to the consultant, the proposed site improvements were designed in a manner to avoid any permanent impacts to Wetland C and the required buffer. This was accomplished in part by focusing wetland impacts to the lower classified Wetland B. The Applicant has proposed implementing the full 100-foot buffer feet around Wetland C for a total buffer size of approximately 102,040 sq. ft. According to the consultant, a key goal of the mitigation plan is to meet or exceed the functions of the existing impacted critical areas. The report states that the existing buffer functions in the area of temporary construction impacts are degraded due to the presence of invasive and non-native vegetation, which has been maintained through mowing. The temporary impacts will be restored at a ratio of 1:1 for a total of 3,344 sq ft of restored buffer. I. Compatibility/Overconcentration. The proposal is compatible with surrounding uses and does not represent an overconcentration of use. The proposed elementary school is compatible with the scale and character of the neighborhood. The building is oriented towards Duvall Ave, a principal arterial, and is directly across from the Hazen High School sports fields. The building design incorporates a significant amount of façade modulation and varying roof pitches and planes, which help reduce the overall scale of the structure as it transitions east and south toward the residential areas. The wetlands area (Wetland C) on the west side of the property provides a large, vegetated buffer that will serve as a visual screen for the single-family residences to the west. The construction of a two-story building results in a smaller building footprint than a building with a single story which allows for additional opportunities for both active and passive recreational programming including an interior plaza, an outdoor classroom, and a large outdoor play area. A buffer area on the south side of heavily landscaped parking lot provides additional transition to the residential area and reduces the visual and noise impacts created by activities at the school. The proposal does not serve to overconcentrate school facility development or use in the surrounding neighborhood. The proposal is adjacent to Hazen High School but otherwise is not near any other school facilities in the surrounding neighborhood. Conclusions of Law 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 12 12 1. Authority. RMC 4-9-200(B)(2)(a)(i) requires site plan review for K-12 facilities. RMC 4-2- 060E requires a hearing examiner conditional use permit in the R8 and R10 zones for K-12 educational facilities. Conditional use permits are classified as a Type III permits by RMC 4-8-080(G). In the absence of the conditional use permit, no Hearing Examiner review would be required for the site plan and it would be classified as a Type II permit by RMC 4-8-080(G). The two modification requests are classified by RMC 4-8-080(G) as a Type I review. RMC 4-8-080(C)(2) requires consolidated permits to each be processed under “the highest-number procedure,” which is the Type III review for the conditional use permit.

The Applicant shall comply with the mitigation measures required as part of the Mitigated Determination of Non-Significance issued by the Renton School District on June 21, 2021 (Exhibit 5): a) There are two existing wetlands on-site. The project avoids impacts to the higher- functioning, Category III, Wetland C, and limits permanent impacts to the lower- functioning, Category IV, Wetland B. The buffer area temporarily impacted by clearing and grading associated with the installation of the multi-use playfield is vegetated with invasive or non-native vegetation. Mitigation and restoration of Wetland C will be provided consistent with City standards. The proposed filling of Wetland B will be mitigated through the use of a wetland bank, as approved by the City. A comprehensive five-year maintenance and monitoring plan is included in the mitigation plan. This plan will ensure that proposed enhancement plantings will be maintained, monitored, and successfully established within the first five years following implementation. b) For security reasons, black vinyl-coated, four- or six-foot-tall chain link fencing is proposed to be installed along the property boundaries (a six-foot-tall cedar fence will be installed along a portion of the southern boundary). To minimize impacts to Wetland C and its buffer, the fabric will be raised 12 inches off the ground to allow the passage of small 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SITE PLAN & CONDITIONAL USE CAO VARIANCE - 17 17 animals. Concrete footings will not be utilized to secure fence posts in wetland areas. The fencing will be reviewed and approved by the City. c) The District will require the selected contractor to develop a construction management plan (CMP) that addresses traffic and pedestrian control during school construction. d) The City collects transportation impact fees and has outlined fee rates for a variety of uses. The transportation impact fee for the elementary school project is calculated to be $356,377. This relates to a fee rate of about $4.63 per square foot (SF) based on the proposed school size of 77,000 SF. The impact fee will be paid, with the final fee established by the City. e) In order to comply with street frontage improvement requirements outlined by the City, the project will dedicate right-of-way along the street frontages of Duvall Ave NE and Chelan Ave NE. f) Frontage improvements will be made along Duvall Ave NE and Chelan Ave NE. The District will coordinate with the City to integrate the dedication areas and frontage improvements with the City’s planned roadway improvement in that segment. g) To mitigate school-related traffic impacts, the project will install a traffic signal (replacing the existing HAWK beacon signal) at the NE 10th Street / Duvall Ave NE intersection. Installation of the new traffic signal will include pedestrian actuated signals and crosswalks on all four legs and final design will be approved by the City. h) To ensure safe routes to school access, the District will construct a sidewalk along the 1155 Duvall Ave NE frontage with ramp at NE 12th St. Design and construction of the sidewalk improvements is being discussed with the City, with the final design to be reviewed and approved by the City. i) To discourage pick-up and drop-off on Chelan Ave NE, the District will install City approved signage at the intersection of NE 10th St and Chelan Ave NE that identifies the street as a no vehicle pick-up or drop-off area. The District will develop a Transportation Management Plan (TMP) to educate families about the access load/unload procedures for the site’s layout. The plan will define clear procedures and travel routes for family vehicles and instruct family drivers not to block or partially block travel lanes with queued or waiting vehicles.
