Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The 58,090 sf (1.33 ac) subject property is currently developed with a multi-family structure on the northern portion of of the property and a standalone billboard abutting the S Grady Way ROW on the southern end of the site (Exhibit 2). A gravel parking areas and a driveway is located near the multi-family structure. The site topography is almost completely flat with only a one-foot elevation change across the site (Exhibit 4). City of Renton (COR) maps has identified the site is within a High Seismic Hazard Area and the within Wellhead Protection Area Zone 2. The applicant’s geotechnical engineer, Earth Solutions NW, completed an initial geotechnical investigation on March 22, 2018 and an additional investigation on May 22, 2020. The initial investigation program included the excavation of two test pits to assess soil conditions and one hollow stem auger boring to a depth of 46.5 feet. The engineer completed three additional borings as part of the updated geotechnical engineering study to depths of 46.5 feet. The soils encountered in the field included a relatively thick layer DocuSign Envelope ID: 2E989192-1BB5-4C86-AEBE-F3D7DE4225C4 City of Renton Department of Community & Economic Development Watershed Apartments Staff Report to the Environmental Review Committee LUA21-000239, ECF, PPUD, FPUD Report of August 23, 2021 Page 4 of 9 SR_ERC_Report_Watershed Apartments_210819_v3_FINAL of very loose to medium dense alluvial sediments consisting predominately of silt and sand layers. According to the Report, a relatively deep topsoil layer was encountered extending up to two feet belo w existing grades. Fill was not encountered but may be present in areas where former structures were removed. Underlying the topsoil, the boring encountered very loose to medium dense alluvial and floodplain deposits consisting of silty fine sand and sand were encountered extending to the maximum exploration depth. A thin layer of peat was encountered at two boring locations (B-1 and B-101 from about 21 to 21.5 feet below grade. Groundwater was encountered approximately six feet (6’) to nine feet (9’) below existing site elevations during the engineer’s investigation. The engineer anticipates that this represents the seasonal groundwater table in the area and the groundwater likely fluctuates and may become shallower during the wet winter months. In addition, two ground water wells were installed on the site to monitor water levels during 2020 to 2021 winter rainy season. Due to the types of soils on the site, the engineer anticipates the potential for liquefaction during a seismic event to be high. Based on the results of a computer model (Liquefy5), total settlement in the range of five (5) to ten (10) inches may occur during seismic event with strong shaking. The geotechnical engineer anticipates that the structure would be six (6) stories in height with one level of concrete and five (5) levels of wood frame supported by a post-tensioned slab. In addition, the geotechnical engineer anticipates that building loads would be moderate and that site grading would include cuts of one foot or less. A preload program is recommended in order to reduce settlement due to the soil conditions encountered. The applicant anticipates approximately 3,400 cubic yards of fill and limited to no excavation (Exhibit 9). If soils are found to be loose or softened in the footing subgrade, they may be replaced with control density fill. According to the geotechnical engineer, soil erosion potential at this project site can be reduced through landscaping and surface water runoff control. Normal erosion control measures include such items as fences, hay bales, mulching, control ditched and diversion trenches. The applicant’s geotechnical engineer recommends supporting the building on a uniform subgrade and foundation support using either piles or a ground improvement due to the presence of liquefiable soils to variable depths below the property. Foundation options include the use rammed aggregate piers, stone columns, or other vibro-installed elements sunk to depth of at least 40 feet. If ground improvement methods are used, the building slab should be underlain with a minimum four-inch thick crushed rock layer. Alternatively, the applicant may utilize 18-inch diameter augercast piles driven to a depth of at least 40 feet. The building slab should be structural supported by the pile foundation system if piles are used. Additional recommendations related to retaining wall construction, drainage, and paving. Earth Solutions NW, LLC recommends that their firm be retained during construction and final design phase of the project. As such, staff recommends a mitigation measure that the applicant comply with the recommendations found in the submitted Geotechnical Investigation, prepared by Earth Solutions NW, LLC, dated June 10, 2020, and future addenda. Additionally, as the geotechnical report was prepared prior to the final design of the project, staff recommends as a mitigation measure, the applicant’s geotechnical engineer review the project’s construction and building permit plans to verify compliance with the geotechnical report(s). The geotechnical engineer shall submit a sealed letter stating that he/she has reviewed the construction and building permit plans and in their opinion the plans and specifications meet the intent of the report(s). Mitigation Measures: 1. The project construction shall comply with the recommendations found in the submitted Updated Geotechnical Study, prepared by Earth Solutions NW, LLC, dated June 10th, 2020, and future addenda.

Nexus: City of Renton Comprehensive Plan Policy L-36; State Environmental Policy Act (SEPA) Environmental Review, RMC 4-3-050 Critical Areas Regulations and RMC 4-4-060 Grading, Excavation and Mining Regulations. 2. Air Impacts: The site is fronted by Williams Ave S to the east, S Grady Way to the south, and is bordered by a multi-family apartment building to the north and a vacant commercial building to the west (Exhibit 3). It is anticipated that some temporary air quality impacts could be associated with site work and building construction required to develop this site. Project development impacts during construction may include dust as a result of grading and exhaust from construction vehicles and equipment. Dust control would be mitigated through the use of temporary erosion control measures, watering or other measures to remediate impacts as needed. Long term emissions from vehicles owned by residents and delivery companies would occur following project completion. No further site specific mitigation for the identified impacts from typical vehicle and construction exhaust is required. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 3. Water a. Ground Water Impacts: The COR mapping system has identified the property located within the Wellhead Protection Zone 2 and therefore open facilities and open conveyance systems may require a liner in accordance with the 2017 Renton Surface Water Design Manual. No open facilities or convenance systems are proposed and therefore the implementation of best management practices (BMPs) for stormwater control is available. Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. The site’s proposed residential use does not typically represent a type of use that would potentially harm the City’s groundwater. Further, site excavations are extremely limited and likely would not encounter groundwater as it was found to be 6 to 10 feet below grade. However, approximately 3,400 cubic yards of fill is anticipated to be brought on the site and therefore any offsite fill materials shall be from a verifiable source in order to ensure it is clear of contaminants. The City’s grading and excavation regulations require imported fill in excess of 50 cubic yards within a Wellhead Protection Zone to provide a source statement certified by a qualified professional or confirm the fill was obtained from a WDOT approved source. No further site specific mitigation for the identified impacts is required if the project complies with the grading and excavation regulations. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. b. Storm Water Impacts: The applicant submitted a Technical Information Report, prepared by AHBL, dated November 2020 (revised May 2021); Exhibit 12) with the application. The report analyzes existing conditions and proposed surface water collection and distribution. DocuSign Envelope ID: 2E989192-1BB5-4C86-AEBE-F3D7DE4225C4 City of Renton Department of Community & Economic Development Watershed Apartments Staff Report to the Environmental Review Committee LUA21-000239, ECF, PPUD, FPUD Report of August 23, 2021 Page 6 of 9 SR_ERC_Report_Watershed Apartments_210819_v3_FINAL According to the TIR Report, the project site is located within the Peak Rate Flow Control Standard Area matching existing conditions and is within the Black River Drainage Basin. The project proposes more than 5,000 sf of new plus replaced impervious surfaces, and so enhanced basic water quality treatment is required. Appropriate BMPs satisfying Core Requirement #9 in the 2017 Renton Surface Water Design Manual are required to mitigate the new runoff to the extent feasible. The applicant proposes to use a BioPod system to treat stormwater runoff for water quality. A direct connection to the existing 24-inch storm main in S Grady Way is proposed via underground pipes and catch basins. The development would be subject to a surface water system development charge (SDC) fees. It is anticipated that the requirements set forth by the 2017 City of Renton Surface Water Design Manual (2017 RSWDM) would be sufficient to mitigate stormwater impacts generated by the proposed development. A Construction Stormwater Permit from Department of Ecology is required due to clearing and grading of the site exceeding one acre. The applicant must obtain the permit and provide proof prior to Civil Permit issuance. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 4. Vegetation Impacts: The subject property contains some existing paved and gravel surface parking, and existing duplex, unmaintained ground cover including Himalayan blackberry and various grasses, as well as five (5) trees. The applicant’s Arborist Report, prepared by Bartlett Urban Forestry Services, dated July 1, 2020 (Exhibit 5), indicated the site contains one significant tree (one 29.7-inch cottonwood tree) and four (4) landmark trees (cottonwood trees ranging in size between 36.2-inches to 56.3-inches). The report identified the three (3) of the cottonwood trees as in fair to good condition and two (2) of the cottonwood trees in poor condition with a high likelihood of failure. The location of four (4) of the cottonwood trees are located within the footprint of the proposed building and the location of the fifth tree, rated as in poor condition, is immediately adjacent to the proposed building which could potentially create a danger to the building and occupants. The landscape architect recommends that all five (5) trees on site be removed and replaced. In addition to the on-site trees, the report identifies six (6) trees on the adjacent properties to the north and west whose driplines extend onto the project site. The size of the trees ranges between 13-inches and 28-inches and the species include Alaska yellow cedar, black cottonwood, Deodar cedar, and Hollywood juniper. The report concludes that all six (6) trees are viable and can be protected by implementing the City’s tree protection standards during construction. The report also concludes that removal of the on-site trees would not impact the viability of the offsite trees. Pursuant to RMC 4-4-130.H, tree retention standards in commercial zones require a minimum of 10 percent (10%) of the site’s significant trees to be retained during and post development. Of the single significant tree and four (4) landmark trees, the applicant is not proposing to retain any of the site’s trees. New tree planting would occur as part of the proposal along the street frontage and around portions of the new building. The landscape plan calls for trees in excess of the three (3) required replacement trees and includes twelve (12) vine maple and nine (9) round-lobed sweet gum species. The proposed new trees would serve as a visual buffer for the proposed structure. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 5. Aesthetics Impacts: The proposed building would be 6-stories in height and with a maximum height of approximately 73’-6” to the top of the stair access roofline (Exhibits 6 and 7). The building includes a step down north side of the building adjacent to the existing apartments on the abutting parcel. The step down would be DocuSign Envelope ID: 2E989192-1BB5-4C86-AEBE-F3D7DE4225C4 City of Renton Department of Community & Economic Development Watershed Apartments Staff Report to the Environmental Review Committee LUA21-000239, ECF, PPUD, FPUD Report of August 23, 2021 Page 7 of 9 SR_ERC_Report_Watershed Apartments_210819_v3_FINAL 5-stories in height with a maximum height of 58’-6” at the parapet and integrated rooftop deck. Exterior features include significant glazing on ground floor facades that face a public ROW and concrete with board formed finish on the remaining façade area. Other features include fiber cement siding in both light and dark colors on the upper levels (levels 2-6), a second floor interior courtyard area, painted metal canopies, dark bronze metal used for the roof coping and individual residential decks. The building’s pedestrian-oriented treatments include architectural design elements at the lower level for human scale including decorative metal screens, first floor floor-to-ceiling windows, longboard metal soffit above the cantilevered second story over the primary entries, and spandrel glazing with graphics. Design elements on the upper levels include tall modulations that extend from the second floor to the roof, sloped roofs with extended parapets, and the integration of multiple outdoor areas including a second floor landscaped courtyard areas above the concrete podium and a fifth floor rooftop deck with programmed space. Units on the south-east, south-west, and east facades include residential decks with dark bronze railings and tempered glass for fall protection that add visual interest and articulation to the bays used for modulation. Outside of the building, ground level planting areas abut the east and southwest facades of structure and include a variety of trees and shrubs for visual interest as well as integrated bench seating for pedestrians. A public promenade area consisting of scored concrete with integrated grass-crete sections would be located adjacent to the south-west façade and includes bench seating for users and aa variety of trees and shrubs (Exhibits 5). The applicant would be required to meet Urban Design Regulations for overlay District ‘A’ as a component of the land use application. For example, the site design requires that building location and orientation include appropriate transitions between buildings, parking areas, and other land uses when siting structures. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 6. Light and Glare Impacts: The addition of new light sources on the subject property would increase the light and glare in the area and could create localized light impacts if not properly designed. Onsite lighting would include interior and exterior building lighting. According to the applicant, no glare from the project is anticipated to be a public safety hazard or interfere with views. At a minimum, a photometric analysis would be required with the civil construction permit application demonstrating compliance with the standards listed in RMC 4-6-060.I. The installation of street lights may be required to comply with the illumination standards for Principal (S Grady Way) and Minor Arterial (Williams Ave S) streets. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 7. Environmental Health Noise Impacts: Noise impacts would primarily result from the construction of the proposed road improvements and new structures. The construction noise would be regulated through the City’s adopted noise level regulations per Chapter 8-7, RMC. The City’s noise regulations limit haul hours between 8:30 am to 3:30 pm, Monday through Friday unless otherwise approved by the Development Services Division. Permitted work hours in or near residential areas are restricted to the hours between seven o’clock (7:00) a.m. and eight o’clock (8:00) p.m. for multi-family construction activities from Monday through Friday. Work on Saturdays is restricted to the hours between nine o’clock (9:00) a.m. and eight o’clock (8:00) p.m. No work is permitted on Sundays (Exhibit 20). Temporary noise impacts are anticipated that would be commonly associated with multi-family development.

Nexus: N/A 8. Transportation Impacts: A Traffic Impact Analysis, prepared by Transpogroup and dated May 2021, was submitted with the project application (Exhibit 15). The submitted report concludes that the proposed development is anticipated to generate 758 average daily trips (ADT) with 50 new AM peak-hour trips and 62 PM peak- hour trips. Since the proposed project is anticipated to generate more than 20 AM or PM peak-hour trips, a full Traffic Impact Analysis was required to be submitted. Increased traffic created by the development would be mitigated by payment of transportation impact fees. The transportation impact fee that is current at the time of building permit application will be levied. The impact fee in effect for 2021 is $6,717.10 per attached dwelling unit. Vehicular access to the site is proposed via Williams Ave S. Street Improvements are regulated by RMC 4- 6-060 – Street Standards. See below: Williams Ave S – Williams Ave S is classified as a Minor Arterial street with an existing right-of-way (ROW) width of approximately 60 feet. To meet the City’s complete street standards for Minor Arterial streets with four (4) lanes a minimum ROW width of 91 feet is required. Williams Avenue S will be converted from a one-way street to a two-way street as part of a City capital improvement project. The project is expected to be completed by the end of 2021. Per RMC 4-6-060 half of street improvements as taken from the ROW centerline shall be required and include a minimum 54-foot paved road (27 feet each side), a 0.5-foot curb, a 12-foot sidewalk with street tree grates, and storm drainage improvements. The City’s Transportation Department has determined a modified minor arterial street section is appropriate for this portion of Williams Avenue S and would result in the curb line remaining in the existing location in order to maintain the existing paved roadway width. The parcel falls just outside of the City’s downtown planning area along Williams Ave S, however the City’s Downtown Streetscape Design Standards and Guidelines will be applied and street improvements fronting this site would be required to include a new 12-foot sidewalk, street trees (4’ x 8’ grates) behind the curb, and street lighting meeting City’s arterial street lighting levels. A minimum 12-foot sidewalk behind the existing curb line with street trees in tree grates will be required. The sidewalk will be approximately 18 feet in width near the intersection of S. Grady Way and Williams Avenue S. Right of way dedication will be required to one foot clear from the back of sidewalk. Per COR Maps approximate required right of way dedication along the Williams Avenue S. frontage will be five- feet (5’). S Grady Way – S Grady Way is classified as a Principal Arterial street with an existing right-of-way (ROW) width of approximately 77 feet. To meet the City’s complete street standards for Principal Arterial streets with five (5) lanes, a minimum ROW width of 103 feet is required. Per RMC 4-6-060 half street improvements as taken from the ROW centerline shall be required and include a minimum 66-foot paved road (33 feet each side), a 0.5 foot curb, a 12-foot sidewalk with street tree grates, and storm drainage improvements. The City’s Transportation Department has determined a modified minor arterial street section to reduce the sidewalk width and establish a landscape strip to buffer pedestrians from the travel lanes is appropriate for this portion of S Grady Way. The modified section would result in the curb line remaining in the existing location and an eight-foot (8’) planter strip and eight-foot (8’) sidewalk would be required. Pedestrian Improvements: As part of the proposed project, sidewalks would be constructed along the frontage of the site and would connect to the existing sidewalk system. Williams Ave S is currently planned to be converted from a one-way to a two-way street as part of a funded City of Renton capital improvement project currently in the preliminary design phase (Exhibit 18). The conversion, combined with the completion of the subject project, is expected to increase traffic volumes at the intersection and DocuSign Envelope ID: 2E989192-1BB5-4C86-AEBE-F3D7DE4225C4 City of Renton Department of Community & Economic Development Watershed Apartments Staff Report to the Environmental Review Committee LUA21-000239, ECF, PPUD, FPUD Report of August 23, 2021 Page 9 of 9 SR_ERC_Report_Watershed Apartments_210819_v3_FINAL increase the number of vehicular turning movements. Future residents of the apartments are highly likely to cross the adjacent intersection in order to access services on the south side of S Grady Way such as restaurants, retail, and a grocery store. In order to ensure that future residents are able to safely cross S Grady Way, staff recommends as a mitigation measure that the applicant install pedestrian signalization and channelization elements for the crossing between the SE corner of the project site and the SW corner of the S Grady Way/Williams Ave S intersection. Elements may include, but are not limited to, a painted crosswalk, a pedestrian signal, or an in-street crossing signs. The proposed elements shall be reviewed and approved by the Current Planning Project Manager prior to civil construction permit issuance. Concurrency – A concurrency recommendation will be provided in the staff report to Hearing Examiner based upon the test of the citywide Transportation Plan, consideration of growth levels included in the LOS‐tested Transportation Plan, payment of a Transportation Mitigation Fee, and an application of site specific mitigation. The development will have to meet the City of Renton concurrency requirements. Increased traffic created by the development would be mitigated by payment of transportation impact fees. The transportation impact fee that is current at the time of building permit application will be levied. Mitigation Measures: The applicant shall install pedestrian signalization and channelization elements for the crossing between the SE corner of the project site and the SW corner of the S Grady Way/Williams Ave S intersection.
