The project site is currently developed with the Hazen High School campus. 3. Access to the site would remain via four (4) existing driveways off of Hoquiam Ave NE and one driveway off of NE 10th St. 4. A total of 414 existing parking stalls are located on the site. Additionally, 34 uncovered bicycle parking spaces are provided onsite near the front building entrance. The applicant has proposed the temporary removal of approximately 34 parking stalls in order to place two (2) temporary portable classroom buildings. 5. The project proposes constructing two (2) temporary classroom buildings. Each portable would be approximately 64 feet (64’) long by 28 feet (28’) wide for a total area of 1,792 sq. ft. Each portable would have two (2) aluminum stair systems and a central ADA ramp for access. The tallest point of each portable building would be sixteen feet (16’) as measured from existing grade. The temporary classrooms will be removed upon completion of the proposed interior improvements. 6. The property is located within the Residential Medium Density (MD) and Residential High Density (HD) Comprehensive Plan land use designation. 7. All parcels comprising the Hazen High School site are located within the Residential-8 (R-8), except for one (1) parcel on the westside of the site zoned Residential Multi-family (RMF) (APN 1023059277). 8. The site topography is bisected at a high point near the middle of the high school with the north-half generally sloping to the north and the south-half generally sloping to the south. 9. Five (5) significant trees are proposed for removal. 10. The site is mapped with sensitive slopes. 11. Approximately 1,977 cubic yards (CY) of fill and 10,275 CY of excavation is proposed. 12. The applicant is proposing to begin construction in summer of 2025 and end in the fall of 2025. 13. No other public or agency comments were received. 14. The Renton School District acted as lead agency for the State Environmental Policy Act (SEPA) Review for the project. On October 28, 2024, the Renton School District issued a Determination of Non-Significance (DNS) for the Hazen High School Modernization project (Exhibit 4). A 14-day comment period commenced on October 28, 2024 and ended on November 12, 2024. No comments were received on the threshold determination according to the Renton School District. 15. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. 16. Comprehensive Plan Compliance: A portion of the site is designated Residential Medium Density (RMD) on the City’s Comprehensive Plan Map. The purpose of the MD designation is to allow a variety of single-family and multi-family development types, with continuity created through the application Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 6 of 29 D_Hazen Modernization_250411_FINAL of design guidelines, the organization of roadways, sidewalks, public spaces, and the placement of community gathering places and civic amenities. A portion of the site is designated Residential High Density (HD). The purpose of the HD designation lands where access, topography, and adjacent land uses create conditions appropriate for a variety of housing unit types, or where there is existing attached residential development. RHD unit types are designed to incorporate features from both detached and attached residential developments, support cost-efficient housing, facilitate infill development, have close access to transit service, and efficiently use urban services and infrastructure. The proposal is compliant with the following development standards if all conditions of approval are met: Compliance Comprehensive Plan Analysis  Policy LU-2: Support compact urban development to improve health outcomes, support transit use, maximize land use efficiency, and maximize public investment in infrastructure and services.  Goal LU-BB: Ensure new development supports a high quality of life with design that is functional and attractive.  Goal LU-FF: Strengthen the visual identity of Renton and its Community Planning Areas and neighborhoods through quality design and development.  Policy LU-48: Respond to specific site conditions such as topography, natural features, and solar access to encourage energy savings and recognize the unique features of the site through the design of subdivisions and new buildings.  Policy LU-54: Complement the built environment with landscaping using native, naturalized, and ornamental plantings that are appropriate for the situation and circumstance and which provide for respite, recreation, and sun/shade.  Policy CF-12: Coordinate with federal, state, regional and local jurisdictions, private industry, businesses and citizens in the planning, design and development of facilities serving and affecting the community. 17. Zoning Development Standard Compliance: The site is comprised of eight (8) parcels. Seven (7) of the parcels are located in the R-8 zone (APNs 1023059057, 1023059278, 1023059201,1023059094, 1023059292, 1023059084, and 1023059072) and one (1) parcel is in the RMF zone (APN 1023059277). The R-8 Zone is established for single-family residential dwellings and is intended to implement the Residential Medium Density Comprehensive Plan Designation. The Residential Multi-Family Zone (RMF) is intended to conditionally allow uses that are compatible with and support a multi-family environment. The RMF allows for the development of both infill parcels in existing multi-family districts with compatible projects and other multi-family development. The proposal is compliant with the following development standards, as outlined in RMC 4-2-110.A, if all conditions of approval are met: Compliance R-8 Zone Development Standards and Analysis N/A Density (R-8): The allowed density range in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per net acre. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and private access easements. Density (RMF): The density range permitted in the RMF zone is a minimum 10.0 up to a maximum of 20.0 dwelling units per net acre. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 7 of 29 D_Hazen Modernization_250411_FINAL private access easements. Individual unit lots are exempt from the maximum net density requirements, however the density of the parent site shall not exceed the maximum net density of the zone. Staff Comment: Not applicable. No dwelling units are proposed. Compliant if condition of approval under FOF 17: Zoning Development Standard Compliance, Setbacks is met Lot Dimensions (R-8): The minimum lot size permitted in the R-8 zone is 5,000 sq. ft. A minimum lot width of 50 feet is required (60 feet for corner lots) and a minimum lot depth of 80 feet is required. Lot Dimensions (RMF): There is no minimum lot size for units in the RMF zone. There is no minimum lot size for attached dwellings. For townhomes, a minimum lot width of 25 feet is required (30 feet for corner lots) and a minimum lot depth of 50 feet is required. Individual unit lots created for townhouses are not required to comply with the minimum lot size, minimum lot width, and minimum depth requirements of the underlying zoning designation, however the whole parent site shall comply with all development standards as though it were a standalone lot. Staff Comment: Upon completion of the lot combination process, the subject property would be approximately 1,464,615 square feet or 33.6 acres in size. The subject property would exceed minimum lot width and depth standards. Compliant if condition of approval is met Setbacks (R-8): The required setbacks in the R-8 zone are as follows: front yard is 20 feet, side yard is 5 feet, secondary front yard (applies to corner lots) is 15 feet, and the rear yard is 25 feet. Setbacks (RMF): The required setbacks in the RMF zone are as follows: front yard is 15 feet for townhouses, except when all access is taken from an alley then 10 feet, or 20 feet for other attached dwellings, side yard is 5 feet for detached units, for attached units the side yard is 0 feet for the attached sides and 5 feet for the unattached sides, secondary front yard (applies to corner lots) is 15 feet for townhouses, or 15 feet for other attached dwellings, and the rear yard is 10 feet for townhouses, or 15 feet for other attached dwelling units. Staff Comment: The existing school building is constructed across the common boundaries of the multiple parcels that make up the site resulting in noncompliance with the required setbacks. Therefore, staff recommends as a condition of approval, the applicant record a formal Lot Combination in order to ensure the existing buildings and proposed improvements are not built across property lines. The instrument shall be recorded prior to the issuance of Temporary Certificate of Occupancy. Building setbacks for the primary school building would be measured from the property lines established following the Lot Combination recording, which would be the exterior lines adjacent to the two (2) street frontages and other shared lot lines. The lot is classified as a corner lot based on the two street frontages adjacent to the site. The proposed building would have a primary front yard setback of approximately 27 feet (27’) from the front property line (Hoquiam Ave NE) and secondary front yard setback of approximately 491 feet from the other front property line (NE 10th St). The side yard setbacks for the existing building would be approximately 77 feet (77’) (north) and approximately 320 feet (320’) (west). The vestibule addition to the front (east) facade would change the building Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 8 of 29 D_Hazen Modernization_250411_FINAL setback. Therefore, the building would comply with all setbacks after the Lot Combination is recorded.  Building Standards (R-8): The R-8 zone has a maximum building coverage of 50% and a maximum impervious surface coverage of 65%. The allowed height of public facilities shall be determined through site plan review. Building Standards (RMF): The RMF zone has a maximum building coverage of 70% for townhouse development and 35% for other attached dwellings. The maximum building coverage may be increased to 45% through the Hearing Examiner site plan review process. The RMF zone has a maximum impervious surface coverage of 75%. In the RMF zone, a maximum building height of 3 stories with a wall plate height of 32 feet is permitted. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6) vertical feet from the maximum wall plate height. If the height of wall plates on a building are less than the states maximum the roof may project higher to account for the difference, yet the combined height of both features shall not exceed the combined maximums. Common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non-exempt vertical projections (e.g., roofs pitched less than 4:12, decks, railings, etc.) may extend up to six (6) vertical feet above the maximum wall plate height if the projection is stepped back one-and- a-half (1.5) horizontal feet from each minimum building setback line for each one (1) vertical foot above the maximum wall plate height. Wall plates supporting a primary roof surface that has only one (1) sloping plane (e.g., shed roof) may exceed the stated maximum if the average of wall plate heights is equal or less than the maximum wall plate height allowed. An additional ten feet (10') of maximum wall plate height and an additional story for a residential dwelling structure may be obtained through the provision of additional amenities such as additional recreation facilities, underground parking, and additional landscaped open space areas; as determined through the site development plan review process and depending on the compatibility of the proposed buildings with adjacent or abutting existing residential development. The maximum wall plate height of a residential structure shall not exceed forty-two feet (42’). Staff Comment: The existing impervious area, which includes buildings, synthetic turf, and paving, totals 704,999 sq. ft. The proposal adds 187,794 sq. ft. of new impervious surface, primarily as the result of installing additional synthetic turf, bringing the total impervious surface to 892,793 sq. ft. This results in an overall impervious coverage of 62.2%, which remains under the maximum allowable limit of 65%. The applicant would also be required to demonstrate compliance with the impervious surface coverage requirements at the time of formal building permit application review. The entry vestibule is the only new building area proposed. The proposed vestibule is approximately 310 sq. ft. Upon completion of the vestibule, the building coverage would total approximately 233,592 sq. ft., or 16.3% of the total site area (233,292 sq. ft / 1,435,329 sq. ft = 0.163). The tallest point of the proposed portable classrooms would be approximately 16 feet (16’) above grade. The proposed vestibule has a maximum height of 13 feet (13’) above grade, which is less than the overall height of the existing school Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 9 of 29 D_Hazen Modernization_250411_FINAL building. See analysis under FOF 18, Site Plan Review: Structure Scale for additional height analysis. Compliance with the building coverage, impervious coverage, and height requirement would also be verified at the time of formal building permit application review. N/A Landscaping: The City’s landscape regulations (RMC 4-4-070) require a 10-foot landscape strip along all public street frontages. Additional minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover, shall be planted within planting strips pursuant to standards set forth in RMC 4-4-070F.2. Nonresidential Development in a Residential Zone: A fifteen-foot (15') wide partially sight-obscuring landscaped visual barrier, or ten-foot (10') wide fully sight-obscuring landscaped visual barrier, is required along common property lines. Parking Lots: Vehicle parking lots shall meet minimum landscape standards: All parking lots shall have perimeter landscaping as provided in RMC 4-4-070H.4. Perimeter landscaping may not substitute for interior landscaping. Interior Parking Lot Landscaping: Surface parking containing between 51-99 parking spaces shall provide a minimum landscape area of 25 square feet per parking space. Interior parking lot landscaping dimensions are stipulated in RMC 4-4-070H.5. Storm Drainage Facility Landscaping: A landscaping strip with a minimum fifteen feet (15') of width shall be located on the outside of the fence, unless otherwise determined through the site plan review or subdivision review process. The landscape strip shall be located entirely within the boundaries of the storm drainage facility tract when associated with a subdivision. Transitional Landscaping: When a Residential Multi-family zone or use is abutting a less intense residential zone: A fifteen-foot (15') wide partially sight- obscuring landscaped visual barrier, or ten-foot (10') wide fully sight-obscuring landscaped visual barrier, is required along the common property line. Staff Comment: Per RMC 4-4-070B.1, the landscaping requirements are not applicable to additions to existing buildings that increase the gross square footage of the building by less than one-third (1/3), or other changes in the use of a property or remodel of a structure that requires improvements equal to or greater than fifty percent (50%) of the assessed property valuation. The proposed project consists of sports field improvements, mechanical and safety upgrades to the school building, and a small vestibule addition. The proposed upgrades would not expand the building’s gross square footage by more than one-third and would not change the property's use or intensity. Additionally, the project does not increase the school’s capacity. Therefore, compliance with the landscaping regulations is not required as outlined in RMC 4-4-070. Compliant if condition of Tree Retention: For residential or institutional development, the City’s adopted Tree Retention and Land Clearing Regulations (4-4-130) require the retention of 30 percent of trees. Tree credit requirements shall apply at a minimum rate of Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 10 of 29 D_Hazen Modernization_250411_FINAL approval is met thirty (30) credits per net acre based on values for existing or new trees as provided in RMC 4-4-130H.1.b.v. Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their associated buffers; and significant trees over sixty feet (60') in height or greater than eighteen inches (18") caliper. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non- native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. Staff Comment: The applicant has proposed the removal of five (5) significant trees. As such, the applicant submitted a Tree Retention and Land Clearing Plan prepared by Atlas Technical Consultants LLC, dated October 4, 2024 (Exhibit 7). Trees proposed for removal include three (3) Douglas fir trees ranging in size from 15.7 inches (15.7”) DBH to 22.3 inches (22.3”) DBH, one (1) 6.3-inch (6.3”) DBH Quaking aspen, and one (1) 14.6-inch (14.6”) Alaska cedar. According to the report, a total of 124 significant trees are located on the site, resulting in a tree retention rate of 96% (119 / 124 = 0.96). Therefore, the project complies with the tree retention requirements in the R-8 and RMF zones. Based on a total site size of approximately 33.6 acres, the applicant would be required to provide a minimum of 1,008 tree credits on the parcel. According to the Tree Retention and Land Clearing Plan, the site provides a total of 749 tree credits for retained trees, or 250 credits less than required. No new trees are proposed, except for off-site street trees, and therefore, the site does not comply with the tree density requirements. Therefore, staff recommends as a condition of approval, that the applicant plant new supplemental trees on the site to achieve the minimum tree density of thirty (30) credits per net acre. The species and locations of the trees shall be indicated on a landscape plan submitted to the Current Planning Project Manager. Alternatively, the applicant may pay into the city’s Urban Forestry Program fund as a fee-in-lieu of providing additional supplemental trees or propose a mix of new supplemental trees and payment of a fee-in-lieu. The applicant shall submit a landscape plan or fee-in-lieu request for review and approval by the Current Planning Project Manager prior to issuance of the building permit application.  Parking: The parking regulations, RMC 4-4-080, require a specific number of off- street parking stalls be provided based on the number of employees and number of busses to be parked onsite. Staff Comment: The following ratios would be applicable to the site: Use Ratio Required Spaces Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 11 of 29 D_Hazen Modernization_250411_FINAL Senior High School A minimum and maximum of one (1) per employee and one (1) per every ten (10) students one (1) off-street parking space for each bus of a size sufficient to park each bus. 325 (based on 155 employees and 1,694 students) According to the applicant, the total number of employees and students at the school would not change as a result of the project. Approximately 414 parking stalls on currently located on the site. Installation of the temporary portable classroom buildings, which would be removed upon completion of the project, would result in the temporary removal of approximately 34 stalls. Based on a total of 155 employees and an approximate enrollment of 1,694 students, the applicant is required to provide 325 total parking stalls in order to meet code. The site currently has more parking stalls than required by code and would continue to after removal of the 34 stalls. While the site would continue to exceed the parking stall maximum after completion of the project, the removal of stalls decreases the non-conformity and therefore the project complies with the parking requirements. The parking conforms to the minimum requirements for drive aisle, parking stall, dimensions and the provision of ADA accessible parking stalls. An existing school bus load and unload area is located off of Hoquiam Ave NE between the south parking lot and the tennis courts. The bus loading area would not be changed as a result of the project. Per RMC 4-4-080F.11, the number of bicycle parking spaces shall be at least equal to 10 percent (10%) of the number of required off-street vehicle parking spaces. The school has 34 existing uncovered bicycle parking spaces, which exceeds the minimum required (325 x .10 = 32.5 bicycle stalls). Therefore, the project complies with the bicycle parking requirements.  Refuse and Recyclables: Per RMC 4-4-090, office, educational and institutional developments require a minimum of 2 square feet per every one thousand (1,000) square feet of building gross floor area be provided for recyclables deposit areas and a minimum of four (4) square feet per one thousand (1,000) square feet of building gross floor area shall be provided for refuse deposit areas. A total minimum area of one hundred (100) square feet shall be provided for recycling and refuse deposit areas. Outdoor refuse and recyclables deposit areas and collection points shall not be located within fifty feet (50') of a lot zoned residential, except by approval through the site development plan review process, or through the modification process if exempt from site development plan review. The gate opening for any separate building or other roofed structure used primarily as a refuse or recyclables deposit area/collection point shall have a vertical clearance of at least eleven (11’) feet but shall not exceed fourteen (14') feet. Staff Comment: After completion of the vestibule, the gross square footage of all school buildings would total 327,705 sq. ft. Therefore, the school is required to provide a total area of 327.7 sq. ft. for recyclables deposit and 655.4 sq. ft. for refuse deposit, totaling 983.1 sq. ft. The school currently provides two (2) 30 cubic yard dumpsters in a centrally located area south of the main school building. The dumpsters are located in an area approximately 1,000 sq. ft. in size, which exceeds the minimum area requirement for office, education, and institutional Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 12 of 29 D_Hazen Modernization_250411_FINAL developments. The area the dumpsters are located is not visible from the public ROW and is screened from the surrounding properties by the existing parking lot landscaping along the southern property line. N/A Fences and Retaining Walls: For commercial, industrial, and nonresidential uses, a maximum of eight feet (8') anywhere on the lot provided the fence, retaining wall or hedge does not stand in or in front of any required landscaping or pose a traffic vision hazard. Staff Comment: The applicant has not proposed the installation of any new fencing or retaining walls on the site. Any new fences proposed shall comply with the fence and wall standards in RMC 4-4-040. Compliance not yet demonstrated Screening: All onsite surface mounted utility equipment shall be screened from public view. Screening shall consist of equipment cabinets enclosing the utility equipment, solid fencing or a wall of a height at least as high as the equipment it screens, or a landscaped visual barrier allowing for reasonable access to equipment. Equipment cabinets, fencing, and walls shall be made of materials and/or colors compatible with building materials. All operating equipment located on the roof of any building shall be enclosed so as to be screened from public view. Staff Comment: No surface or roof-mounted equipment is proposed at the time of land use application. If equipment is proposed at the time of building permit submittal, compliance with the screening requirements would be reviewed at that time. 18. Site Plan Review: Pursuant to RMC 4-9-200B, Site Plan Review is required for all K-12 educational institutions regardless of zone. Site Plan applications are evaluated for compliance with the specific requirements of the RMC 4-9-200E.3 and the following table contains project elements intended to comply with level of detail needed for Site Plan requests: Compliance Site Plan Criteria and Analysis  a. Comprehensive Plan Compliance and Consistency. Staff Comment: See previous discussion under FOF 16, Comprehensive Plan Compliance. Compliant if conditions of approval are met b. Zoning Compliance and Consistency. Staff Comment: See discussion under FOF 17, Zoning Development Standard Compliance. N/A c. Design Regulation Compliance and Consistency. Staff Comment: The Residential Design and Open Space Standards are not applicable to senior high educational institutions located in R-8 zone. N/A d. Planned action ordinance and Development agreement Compliance and Consistency. Staff Comment: Not applicable, the subject property is not located in a Planned Action Ordinance area and a Development Agreement is not proposed.  e. Off-site Impacts. Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 13 of 29 D_Hazen Modernization_250411_FINAL Structures: Restricting overscale structures and overconcentration of development on a particular portion of the site. Staff Comment: The proposed improvements are limited to non-structural field upgrades and a small vestibule addition near the front of the building facing Hoquiam Ave NE. Additionally, two (2) temporary portables would be placed within an existing parking area in an interior section of the site. The location and scale of these improvements are respectful of the surrounding residential properties, as the vestibule addition is a minor extension to the existing structure, and the field upgrades do not introduce new buildings or permanent structures. The temporary portables, positioned within a developed portion of the site, are set back from residential properties and are proposed to be mostly hidden from view along Hoquiam Ave NE. Their placement within the interior parking area minimizes visual and spatial impact on the surrounding neighborhood. As a result, the school would continue to be integrated well within the residential context, and the proposed improvements would not create an overscaled development or an overconcentration of structures on the site. Circulation: Providing desirable transitions and linkages between uses, streets, walkways and adjacent properties. Staff Comment: See “Internal Circulation” under criterion ‘g’ below for analysis. Utilities, Loading and Storage Areas: Locating, designing and screening storage areas, utilities, rooftop equipment, loading areas, and refuse and recyclables to minimize views from surrounding properties. Locate utilities underground consistent with RMC 4-6-090. Staff Comment: The applicant has not proposed any changes to the trash and recyclables area and the structure does not contain any rooftop equipment. See additional analysis under FOF 17, Zoning Development Standard Compliance: Refuse and Recycling and Screening Views: Recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features. Staff Comment: Due to the small size of the temporary portable classrooms and proposed vestibule relative to the existing school building and highly developed nature of the campus site, the additions would not significantly impact any of the limited views in the immediate area. Landscaping: Using landscaping to provide transitions between development and surrounding properties to reduce noise and glare, maintain privacy, and generally enhance the appearance of the project. Staff Comment: No significant landscaping is proposed for removal as part of the project. Existing landscaping onsite includes parking lot perimeter and interior landscaping, a large treed area on the western edge of the campus site, and areas near the central plaza by the front entrance. The existing landscaped areas help provide transitions between campus and the predominantly single- family residential neighborhood while enhancing the overall site. See comments and condition of approval related to tree density under FOF 17, Zoning Development Standard Compliance: Tree Retention. Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 14 of 29 D_Hazen Modernization_250411_FINAL Lighting: Designing and/or placing exterior lighting and glazing in order to avoid excessive brightness or glare to adjacent properties and streets. Staff Comment: The applicant has proposed ten (10) new field lights around the existing multipurpose areas and baseball fields. Pole heights vary from 60 to 80 feet (60-80’) tall. Mature vegetation along the west and southwest perimeter of the site helps screen the residences to the west and limits light impacts. Proposed lighting would be Light Emitting Diode (LED), full cutoff and shielded in order to prevent light spillage. In addition, according to the applicant, lighting would only be used until 10:00 pm.  f. On-site Impacts. Structure Placement: Provisions for privacy and noise reduction by building placement, spacing and orientation. Staff Comment: The proposed improvements, including non-structural field upgrades and a small vestibule addition near the front of the building facing Hoquiam Ave NE, are minimal in scale and do not introduce new permanent structures beyond the existing school footprint. Additionally, the two (2) temporary portables would be located within an existing parking area in an interior section of the site, ensuring they do not create new privacy or noise concerns beyond typical high school activities. Their placement within a developed portion of the site maintains the existing character and function of the campus. Structure Scale: Consideration of the scale of proposed structures in relation to natural characteristics, views and vistas, site amenities, sunlight, prevailing winds, and pedestrian and vehicle needs. Staff Comment: The vestibule addition is a modest extension to the existing building and does not alter the overall scale or visual presence of the school. The field improvements are non-structural and would not introduce new vertical elements that impact views, sunlight, or site circulation. The two (2) temporary portables, placed within an interior parking area, are significantly smaller than the main school building and are not anticipated to create a noticeable visual change to the site. Natural Features: Protection of the natural landscape by retaining existing vegetation and soils, using topography to reduce undue cutting and filling, and limiting impervious surfaces. Staff Comment: The field improvements and vestibule addition would be constructed within already developed areas, minimizing impacts to the natural landscape. While minor utility trenching may be required for the temporary portables, it would be limited in scope and would not significantly alter the site’s topography or increase impervious surfaces. Reducing Parking Impervious Areas: Design parking areas to minimize impervious surfaces, including but not limited to: (1) breaking up parking areas and directing stormwater flows to multiple low impact development features such as bioretention areas; (2) locating parking near trees to provide storm water uptake; (3) retaining or adding vegetation to parking areas; (4) placing existing parking that exceeds maximum parking ratios in Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 15 of 29 D_Hazen Modernization_250411_FINAL permeable pavement designed consistent with the Surface Water Design Manual in RMC 4-6-030; and (5) using other low impact development techniques consistent with RMC 4-6-030. Staff Comment: No expansions of the existing surface parking areas are proposed. Landscaping: Use of landscaping to soften the appearance of parking areas, to provide shade and privacy where needed, to define and enhance open spaces, and generally to enhance the appearance of the project. Landscaping also includes the design and protection of planting areas so that they are less susceptible to damage from vehicles or pedestrian movements. Staff Comment: See FOF 17, Zoning Development Standard Compliance: Landscaping for analysis.  g. Access and Circulation. Location and Consolidation: Providing access points on side streets or frontage streets rather than directly onto arterial streets and consolidation of ingress and egress points on the site and, when feasible, with adjacent properties. Staff Comment: The site is currently accessed via four (4) existing driveways off of Hoquaim Ave NE and one off of NE 10th St, the site’s only street frontages. No changes to the access points on the site are proposed. Internal Circulation: Promoting safety and efficiency of the internal circulation system, including the location, design and dimensions of vehicular and pedestrian access points, drives, parking, turnarounds, walkways, bikeways, and emergency access ways. Staff Comment: The applicant has proposed minor changes to the site’s pedestrian circulation in order to provide safe access to the temporary portable classrooms. For pedestrians, a striped eight-foot (8’) wide crosswalk is proposed connecting a sidewalk and plaza entry area on the westside of the school building. For vehicles, a drive aisle in the parking lot near the portables would remain clear due to its designation as a fire lane. Therefore, emergency vehicle access on the site would not change. Overall, the large site allows for adequate vehicle and pedestrian access via the existing internal driveways and pedestrian linkages connecting the track area, pool building, both parking lots, and the main school building, which would continue after construction of the portable buildings, vestibule, and field improvements. Loading and Delivery: Separating loading and delivery areas from parking and pedestrian areas. Staff Comment: No changes to the loading and delivery areas are proposed. Transit and Bicycles: Providing transit, carpools and bicycle facilities and access. Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 16 of 29 D_Hazen Modernization_250411_FINAL Staff Comment: Per RMC 4-4-080F.11.a, bicycle parking spaces are required at ten percent (10%) of the number of required off-street parking spaces. See FOF 18, Zoning Development Standard Compliance: Parking for analysis. King County Metro Transit provides bus service in the vicinity of the project site with the closest stops served by Route 105, 114 and Route 240. The routes have stops located approximately one-half (0.5) mile northwest of the site near the intersections of NE Sunset Blvd and Duvall Ave NE. School bus transportation is provided to non-walkers attending the existing high school. Pedestrians: Providing safe and attractive pedestrian connections between parking areas, buildings, public sidewalks and adjacent properties. Staff Comment: A new eight-foot (8’) wide crosswalk is proposed across the south parking area adjacent to the church parcel in order to connect the proposed temporary portable buildings with the existing sidewalk system near the main building (Exhibit 3). The pathway would be required to maintain ADA compliance throughout its entire length. See Advisory Notes (Exhibit 12) for additional comments. See above under ‘Internal Circulation’ for additional analysis.  h. Open Space: Incorporating open spaces to serve as distinctive project focal points and to provide adequate areas for passive and active recreation by the occupants/users of the site. Staff Comment: Open space is currently provided on the site via multiple elements including the various sports fields, grassy areas adjacent to the pedestrian walkways, and an interior courtyard adjacent south of the proposed portables. No new significant open space is proposed as part of the project and no existing open space would be eliminated.  i. Views and Public Access: When possible, providing view corridors to shorelines and Mt. Rainier, and incorporating public access to shorelines Staff Comment: The proposed vestibule addition and temporary portable classroom structures would not block view corridors to shorelines or Mt. Rainier. The public access requirement is not applicable to the proposal.  j. Natural Systems: Arranging project elements to protect existing natural systems where applicable. Staff Comment: No noteworthy natural systems are located on or adjacent to the site. See FOFs 19, 20, and 21 for additional analysis and recommended conditions of approval k. Services and Infrastructure: Making available public services and facilities to accommodate the proposed use: Police and Fire. Staff Comment: 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. This includes the installation of one (1) new fire hydrant to serve the two (2) temporary portables. The need for an extra hydrant would be determined by the Renton Regional Fire Authority at the time of formal building permit application review. A Fire Impact Fee, based on amount per square foot per the City of Renton Fee Schedule in effect at the Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 17 of 29 D_Hazen Modernization_250411_FINAL time of building permit application submittal, would be applicable to the proposal. See Exhibit 12, Advisory Notes, for additional comments and recommendations from both departments. Water and Sewer. Staff Comment: Water and sewer service to the site is provided by the City of Renton. The portable classrooms would not be hooked up to either water or sewer. No changes to the existing water or sewer connections are proposed. The proposed geothermal well drilling would take place within 15 feet (15’) of a City of Renton 10-inch (10”) water main, with service and return lines crossing over the main before entering the school building. To protect the water main during construction, precautions shall be taken, including restricting heavy machinery and drilling equipment from operating over the main or within the water easement. Vibrational testing will be required, and any machinery crossing the main in unpaved areas must use sheeting or a similar protective mechanism to prevent damage. In addition, the well drilling would take place within 30 feet (30’) of an existing private 8-inch (8”) clay sewer main. To protect the main during construction, precautions shall be taken including but not limited to, restricting heavy machinery and drilling equipment from operating over it, conducting vibrational testing or CCTV monitoring, and using sheeting or similar protective measures when crossing unpaved areas to prevent damage. See Exhibit 12, Advisory Notes, for additional information and recommendations. Drainage. Staff Comment: The applicant has proposed approximately 187,794 sq. ft. of new impervious surface. As such, the applicant submitted a Technical Information Report prepared by Jacobson Consulting Engineering and dated September 24, 2024 (Exhibit 8) with the submittal materials. Based on the city’s flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the May Creek – Honey Creek Drainage Basin. The project is subject to the requirements in the 2022 Renton Surface Water Design Manual (RSWDM). City records show that the majority of the site is collected and conveyed to the southwest through a series of private stormwater facilities which ultimately discharge into the public storm drainage system in NE 10th St. A portion of the northeast school parking lot is collected and conveyed via a private storm drainage system that flows north in Hoquiam Ave NE. A portion of the southeast school parking lot, ball fields, and tennis courts are collected and routed into the conveyance system in Hoquiam Ave NE that runs north to south (see city stormwater plan no. R-28510C). City records indicate three (3) discharge points from the site with one (1) discharge at the site’s northeast corner, another at the site’s east property line close to the site’s southeast corner, and the other at the site’s southwest corner. The project involves replacing existing grass sports fields with synthetic turf, triggering the requirement for a formal stormwater detention system (Core Requirement #3, RSWSM). The applicant proposes three (3) separate “Rainvault” storm drainage detention systems, which will undergo detailed Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 18 of 29 D_Hazen Modernization_250411_FINAL review during the civil construction permit process to ensure compliance with the 2022 RSWDM flow control standards. For water quality (Core Requirement #8, RSWSM), the applicant has not proposed water quality treatment facilities, stating that the project does not exceed thresholds for pollution-generating impervious and pervious surfaces. However, since the 2022 RSWDM defines synthetic turf fields as pollution- generating surfaces, the applicant must demonstrate through manufacturer data, Department of Ecology (DOE) approval, or independent analysis that the proposed turf infill is non-pollution generating. If this cannot be confirmed, water quality treatment meeting "enhanced basic" standards will be required. Additionally, on-site Best Management Practices (BMPs) are required to meet Core Requirement #9. The applicant currently proposes only amended soils for landscaped areas, citing infeasibility for other BMPs. A final determination on BMP feasibility will be made during the civil construction permit review process. Erosion control measures to meet the city requirements shall be provided. Core and Special Requirements must be addressed in the Final Technical Information Report (TIR). See Exhibit 12, Advisory Notes, for additional comments. The development is subject to a system development charge (SDC) for stormwater. The 2024 SDC for stormwater is $0.92 per square foot of new impervious surface area, but not less than $2,300.00. The fee that is current will be charged at the time of construction permit issuance. Transportation. Staff Comment: The applicant contends the enrollment at the school would not change as a result of the proposed portable classrooms and therefore, no additional trips would be created. City staff concurs with this assessment and concludes that a formal Traffic Impact Analysis is not required. The proposed development site has frontage on Duvall Ave NE, NE 10th St, and Hoquiam Ave NE. Since the project involves exterior improvements exceeding $175,000, frontage improvements are required per Renton Municipal Code (RMC) 4-6-060. Duvall Ave NE (Principal Arterial) – The existing right-of-way (ROW) is 83 feet (83’), whereas a five-lane principal arterial requires 103 feet (103’) per RMC. However, due to recent city upgrades (sidewalks, bike lanes, median, and streetlights), the Transportation Division supports retaining the current configuration. A modification request must be approved before the civil construction permit is issued (see FOF 21). Hoquiam Ave NE (Collector Arterial) – The existing ROW is 60 feet (60’), which is below the required 83 feet (83’) for a two-lane collector arterial. The Transportation Division supports keeping the current layout, provided the following updates are made: o Upgrade all driveways, curb ramps, and crosswalks to meet ADA and city standards, including the northeast corner ramp. o Install a pedestrian-activated Rectangular Rapid Flashing Beacon (RRFB) at the NE 11th Ct crosswalk near the school entrance. Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 19 of 29 D_Hazen Modernization_250411_FINAL o Obtain approval for the modification request before the civil construction permit is issued. A modification request must be approved before the civil construction permit is issued (see FOF 20). NE 10th St (Residential Access Street) – The existing ROW is 60 feet (60’), exceeding the required 53 feet (53’). The school’s frontage includes a mix of improved and unimproved ROW. The Transportation Division supports maintaining the existing layout with the following conditions: o Upgrade all driveways, curb ramps, and crosswalks to meet ADA and city standards. o Improve the unimproved section with half-street upgrades (sidewalk, lighting, planter strip, and street trees) while ensuring feasibility with adjacent hillside constraints. o Install temporary barricades until future development extends the road connection. o Obtain approval for the modification request before the civil construction permit is issued. A modification request must be approved before the civil construction permit is issued (see FOF 19). On-site and off-site ADA compliance, curbing, sidewalks, and parking lot improvements will be reviewed during the civil construction permit process. A grading plan must demonstrate compliance with ADA and city standards. All frontage improvements must include updated street lighting and street trees per city standards. A photometric analysis is required for new lighting along NE 10th St. Any removed or impacted streetlights must be replaced with fixtures meeting current city standards. The proposal has passed the city’s Traffic Concurrency Test per RMC 4-6-070.D (Exhibit 11), which 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. N/A l. Phasing: The applicant is not requesting any phasing. N/A m. Stormwater: Providing optimal locations of stormwater infiltrating low impact development facilities. Avoiding placement of buildings or impervious areas on soils with infiltration capability to the maximum extent practicable. Staff Comment: The applicant submitted a Subsurface Exploration, Geologic Hazard, and Geotechnical Engineering Report, prepared by Associated Earth Sciences, Inc., dated August 26, 2024 (Exhibit 9). The report indicates that the site consists of dense fill soils, silty Vashon ice-contact deposits, and very dense Vashon Lodgement till soils. Due to these soil conditions and high groundwater levels, infiltration is deemed infeasible, and alternative stormwater management methods should be considered. Staff agrees with the assessment and will finalize the review of infiltration options during the civil construction permit process.

Street Modification Analysis (NE 10th St): Pursuant to Renton Municipal Code (RMC) 4-9-250D, the applicant is requesting a Modification from RMC 4-6-060F.2, Minimum Design Standards for Public Streets and Alleys, for NE 10th St. NE 10th St is classified as a Residential Access street with two (2) travel lanes, a parking lane, and flush five-foot (5’) wide sidewalks on both sides. The road has an existing right-of-way (ROW) width of approximately 60 feet (60’). In order to meet the city’s complete street standards for a Residential Access street, the minimum ROW is 53 feet (53’). Half street improvements would include a pavement width of 20 feet (20’) (10 feet from centerline), a one-half foot (0.5’) wide curb, an eight-foot (8’) wide planting strip, a five-foot (5’) wide sidewalk, two feet (2’) of clear space at back of walk, street trees, and storm drainage improvements. The Hazen High School frontage along NE 10th St includes a partially improved right-of-way from Field Ave NE to Hoquiam Ave NE, featuring a curb-adjacent sidewalk with a parking lane serving as a traffic-calming buffer and grass landscaping behind the sidewalk. The remaining frontage consists of an unimproved right-of-way, which includes a partial turn-around/half cul-de-sac at the intersection with Field Ave NE and an asphalt walking path extending west from Field Ave NE to approximately 100 feet (100’) east of Duvall Pl NE. The applicant is proposing to retain the existing improvements with some modifications, including upgrading the existing ADA ramp at the NW corner of Hoquiam Ave NE and NE 10th St to meet City of Renton code, adding an eight-foot (8’) wide planter strip with new street trees and street lights along NE 10th St from the cul-de-sac (where asphalt trail starts) to the west property line south of the football field, and adding a five-foot (5’) wide sidewalk behind the planter strip. The proposal is compliant with the following modification criteria, pursuant to RMC 4-9-250D, if all conditions of approval are met. Therefore, staff is recommending approval of the requested modification as noted below, if all conditions of approval are met: Compliance Street Modification Criteria and Analysis  a. Substantially implements the policy direction of the policies and objectives of the Comprehensive Plan Land Use Element and the Community Design Element and the proposed modification is the minimum adjustment necessary to implement these policies and objectives. Staff Comment: The Land Use Element has applicable policies listed under a separate section labeled Promoting Efficient Use of Land. These policies address walkable neighborhoods, safety, and shared uses. The intent of the policies is to promote new development with walkable places that support grid and flexible grid street and pathway patterns, and are visually attractive, safe, and healthy environments. The requested street modification is consistent with these policy guidelines. Staff finds that the modification request to allow an alternative street section is consistent with the policy and objectives of the Comprehensive Plan Land Use element and is the minimum adjustment necessary. Compliant if conditions of approval are met b. Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment. Staff Comment: The city’s Public Works Transportation section and Development Engineering section have reviewed the traffic volumes and patterns on NE 10th St and have determined that the proposed modification to the street section is appropriate due to the current volume and speed of traffic on the street, if all recommended conditions of approval are complied with. This recommendation was based on the fact that the extent of the existing roadway, after the required Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 21 of 29 D_Hazen Modernization_250411_FINAL frontage improvements are installed, would meet the transportation needs of the surrounding area while providing the required separation between the vehicular and pedestrian travel ways as required by the code. Recommended Conditions of Approval: 1) All existing driveway cuts, curb ramps and crosswalks along the NE 10th St frontage shall be upgraded to meet current city and ADA standards, including receiving ramps for crosswalks. 2) The unimproved portion of NE 10th St shall be upgraded to provide half- street improvements including sidewalk, street lighting, planter strip and street trees as feasible in relation to the adjacent hillside to the north, and asphalt pavement to the furthest extent south as feasible. The final design of the improvements including pavement width, planter width, street lighting locations, and street tree locations, shall be reviewed and approved by the Public Works plan reviewer. Temporary barricades shall be installed until such a time that the properties to the south develop and continue the through connection. Therefore, staff finds the modification would meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment.  c. Will not create substantial adverse impacts to other property(ies) in the vicinity.

In order to meet the city’s complete street standards for Collector Arterial streets, the minimum ROW is 83 feet (83’), necessitating approximately 10 feet (10’) of ROW dedication in front of the site for half-street improvements. In addition, half street improvements would include a pavement width of 30 feet (30’) (15 feet [15’] from centerline), a one-half foot (0.5’) wide curb, a five-foot (5’) wide bike lane, an eight-foot (8’) wide parking lane, an eight-foot (8’) wide planting strip, an eight-foot (8’) wide sidewalk, two feet (2’) of clear space at back of walk, street trees, and storm drainage improvements. The applicant is proposing to retain the existing street section and improvements, which include a curb-adjacent sidewalk with a parking lane serving as a traffic-calming buffer. In addition, mature landscaping, including established street trees, are located behind the sidewalk. If new improvements were installed, the trees would need to be removed. Staff concurs with this justification and supports the modification request. The proposal is compliant with the following modification criteria, pursuant to RMC 4-9-250D, if all conditions of approval are met. Therefore, staff is recommending approval of the requested modification as noted below, if all conditions of approval are met: Compliance Street Modification Criteria and Analysis  a.

Staff Comment: The Land Use Element has applicable policies listed under a separate section labeled Efficient Use of Land. These policies address walkable neighborhoods, safety, and shared uses. The intent of the policies is to promote new development with walkable places that support grid and flexible grid street and pathway patterns, and are visually attractive, safe, and healthy environments. The requested street modification is consistent with these policy guidelines. Staff finds that the modification request, to allow an alternative street section in order to protect established and mature street trees, is consistent with the policy and objectives of the Comprehensive Plan Land Use element and is the minimum adjustment necessary. Compliant if conditions of approval are met b. Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment. Staff Comment: The city’s Public Works Transportation section and Development Engineering section have reviewed the traffic volumes and patterns on Hoquiam Ave NE and have determined that the proposed modification to the street section is appropriate due to the current volume and speed of traffic on the street, if all conditions of approval are met. This recommendation was based on the fact that the extent of the existing roadway, after the required frontage improvements are installed, would meet the transportation needs of the surrounding area while providing the required separation between the vehicular and pedestrian travel ways as required by the code. Recommended Conditions of Approval: 1) All existing driveway cuts, curb ramps and crosswalks along Hoquiam Ave NE shall be upgraded to meet current city and ADA standards, Docusign Envelope ID: 7DB5BAF4-01DD-47AF-8A68-E3AC0877E8A4 City of Renton Department of Community & Economic Development Administrative Staff Report Hazen High School Modernization LUA24-000349, SA-A, MOD, MOD, MOD Report of April 11, 2025 Page 23 of 29 D_Hazen Modernization_250411_FINAL including the northern-most ramp adjacent to the northeast property corner of the site.
