Exhibit 13 ADVISORY NOTES TO APPLICANT Page 2 of 4 LUA25-000124 DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: May 5th, 2025 June 20, 2011 TO: Alex Morganroth, Principal Planner FROM: Yong Qi, Civil Engineer III, Plan Reviewer SUBJECT: Boeing Crew Shelters 737 Logan Ave N, Renton, WA LUA25-000124 I have reviewed the application for the Boeing Crew Shelters located at 737 Logan Ave N (parcel No. 0723059001) and have the following comments: EXISTING CONDITONS: The site is approximately 153.28 acres of Boeing Campus. It is fronted by City of Renton public park to the west, Lake Washington to the north, and retail/commercial properties to the south and east. It is comprised of one king county parcel number 072305-9001. Per the land-use application, the project scope is concentrated along the northern edge of the parcel abutting Lake Washington. WATER: The project is within the City of Renton’s water service area in the Kennydale 308 Pressure Zone. There is an existing 12-inch water main located within Logan Ave N that runs along the east property line (per record drawing W-314905) and a 12-inch water main located in N 6th St along the south property line (per record drawing W-274301). SEWER: There is an existing 12-inch public sewer main that stubs at N 8th St in front of the property (per record drawing S-314912). STORM: The parcel has multiple direct outfalls to Lake Washington on the north property line. There is an existing private conveyance system that provides drainage to the project site. STREETS: The proposed development fronts Logan Ave N along the east property line and N 6th St along the south property line. Logan Ave N is classified as a Principal Arterial. Existing right-of-way (ROW) width according to the King County Assessor map is 105 feet, consisting of approximately 38-foot paved road, consisting of (3) 11-foot lanes, a 5-foot bike lane, and an 8-foot sidewalk on the project side of the frontage. N 6th St is classified as a Commercial-Mixed Use & Industrial Access Street. Existing right-of-way (ROW) width according to the King County Assessor map is 72 feet, consisting of approximately 38-foot paved road, and on the project side, 11-foot lane left turn lane, 11-foot lane, 2-foot asphalt edge, and 13.5-feet of landscaping. WATER COMMENTS: ADVISORY NOTES TO APPLICANT Page 3 of 4 LUA25-000124 1. The project does not propose to remove or replace existing water main, add floor space to buildings nor revise fire suppression systems or existing hydrants. a. Applicant shall provide accurate survey information of all water mains, services and hydrants within the work area and provide adequate protection of these facilities during construction. b. The submitted preliminary civil plan depicts several structures being placed on-top of existing private waterlines. Structures to be relocated away from existing utilities prior to next building permit submittal. SEWER COMMENTS: 1. There are no sewer facilities at or adjacent to proposed shelters. a. Applicant shall provide accurate survey information of all sewer mains, services, lift station and appurtenances within the work area and provide adequate protection of these facilities during construction. 2. If applicable, any dewatering activity that is proposed to be discharged to the sewer system, must receive approval from the City and King County Industrial Waste Program before discharge. SURFACE WATER 1. Drainage plans and a drainage report complying with the adopted 2022 Renton Surface Water Design Manual is required. Refer to Figure 1.1.2.A – Flow Chart of the 2022 Renton Surface Water Design Manual (RSWDM) to determine what type of drainage review is required for this site. a. A Technical Information Report prepared by Sitts & Hill Engineers, Inc. dated February 24, 2025, was submitted by the applicant with the Land Use Application, which was prepared following the 2022 Renton Surface Water Design Manual (RSWDM). The drainage assessment indicates that a full drainage review is required. Staff concurs with the assessment. b. Core Requirement #2, off-site analysis: his project does not include more than 2,000 square feet of new impervious surface, more than ¾ acre of new pervious surface, or modifications to existing drainage facilities, and does not include work in landslide, steep slope, or erosion hazard areas. Therefore, this project is exempt from Core Requirement #2. Staff concurs with the assessment. c. Core Requirement #3, per the TIR, this project is proposing less than 5,000 square feet of new plus replaced impervious surface and less than ¾ acres of new pervious surface and is therefore exempt from Core Requirement #3. Staff concurs with the assessment. 2. Conveyance, Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to 2022 RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. a. This project proposes no new conveyance systems or modifications to existing conveyance systems. And this project will not change the flow characteristics compared to the preconstruction project site. Therefore, staff concurs with the assessment that Core Requirement #4 of conveyance analysis is not required. 3. Construction Stormwater Pollution Prevention, Core Requirement #5: The preliminary civil plan and drainage assessment include an ESC and CSWPP plan. a. The TIR depicts that since no activities related to this project are expected to create sediment or other stormwater pollutants, a Temporary Erosion and Control (TESC) Plan will not be included in the construction plan set. Staff concurs with the assessment. b. A CSWPP plan is provided as part of the land use application, which will be further reviewed as part of the building permit application. 4. Water Quality, RSWDM Core Requirement #8: If the new plus replaced pollution generating impervious (PGIS) surface exceeds 5,000 SF, the applicant will be required to provide enhanced basic water quality treatment. a. The TIR indicates the project is exempt from Core Requirement #8 since this project is proposing less than 5,000 square feet of new plus replaced PGIS and less than ¾ acres of new PGPS. Staff concurs with the assessment. ADVISORY NOTES TO APPLICANT Page 4 of 4 LUA25-000124 5. Appropriate on-site BMPs satisfying Core Requirement #9 will be required to help mitigate the new runoff created by this development to the maximum extent feasible. On-site BMPs shall be evaluated as described in Section C.1.3 of the 2022 RSWDM. A preliminary drainage plan, including the application of on-site BMPs, shall be included with the land use application, as appliable to the project. The final drainage plan and drainage report must be submitted with the utility construction permit. a. The TIR depicts that the construction will occur above existing concrete pavement, neither soil amendment nor downspout BMPs apply to the project. The proposed construction will also not involve removal or replacement of any existing concrete pavement. Therefore, none of the listed BMPs per section 1.2.9.2.2 are feasible for implementation on the project site, and will not be implemented. Staff concurs with the assessment. 6. A geotechnical report for the site is required and shall be submitted with the land use application. Information concerning the soils, geology, drainage patterns, vegetation present, water table and soil permeability, with recommendations of appropriate on-site BMP options with typical designs for the site from the geotechnical engineer, shall be submitted with the application. The geotechnical report should include an on-site infiltration test to clearly show if the site is suitable or unsuitable for infiltration. a. A geotechnical report is not prepared and provided as part of the land use application since the construction will occur above existing concrete pavement, therefore a geotechnical report is deemed not required. 7. The development is not subject to a surface water system development charge (SDC) fees since no new impervious surface area is proposed. TRANSPORTATION 1. The proposed project is interior to the property and does not trigger street improvements as it is not adding permanent structure additions. GENERAL COMMENTS 1. Additional Building Permit Applications will be required for the following: a. Any retaining walls that exceed 4 feet in height, as defined by RMC 4-4-040. b. Detention vaults for storm water flow control. c. Demo of any existing structures on the project site(s)
