See Development Engineering Memo dated October 9, 2025. Fire Authority: (Contact: Corey Thomas, 425-276-9582, cthomas@rentonrfa.org) 1. The fire impact fees are applicable at the rate of $421.98 per single-family unit. This fee is paid at building permit issuance. 2. The fire flow requirement for single-family homes is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one fire hydrant is required within 300 feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. Water is provided by King County Water District 90. A water availability certificate will be required from them. The water main in NE 8th Street is only a 6-inch main and thus has limited fire flow EXHIBIT 14 Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 ADVISORY NOTES TO APPLICANT Page 2 of 2 LUA24-000390 available. New water mains and fire hydrants will be required to be extended into the sites. Proposed new water main appears adequate. 3. Fire department apparatus access roadways are required to be a minimum of 20 feet wide fully paved, with 25 feet inside and 45 feet outside turning radius. Fire access roadways shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required within 150 feet of all points on the buildings. Dead end streets that exceed 150 feet in length require an approved turnaround. Dead end access roadways more than 300 feet long will require a full 90- foot cul-de-sac. This applies to both proposed access roadways. NE 8th Street is not a public street, it is a private road with access gates across it, thus treated as a dead-end street. Private access easements must be obtained and recorded prior to short plat approval. Dead end access roadways in excess of 500 feet require all new homes to have an approved fire sprinkler system. Approved turnarounds cannot be part of the driveway for a single-family home. 4. The applicant has proposed using hammerhead type turnarounds at the intersection of NE 8th Street and Pasco Pl NE and has applied for a variance to do so. The Renton Regional Fire Authority has approved the variance request with the condition that all new homes in this plat shall be equipped with an approved residential fire sprinkler system.

Applicant shall obtain a water availability certificate from KCWD90 and provide it with the construction permit submittal. a. A water availability certificate from Water District 90 was provided with the Land Use Submittal. 2. Review of the water plans will be conducted by KCWD90 and the Renton Regional Fire Authority. 3. Plans approved by KCWD90 shall be routed to the City for final review prior to construction permit issuance. Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 SEWER COMMENTS 1. A minimum 8-inch sewer main is to be provided within the proposed development proving service to all lots. Individual sewer stubs and side sewers are required for each single-family residence. The sewer main, stubs and side sewers shall conform to the standards in RMC 4- 6-040 and City of Renton Standard Details. a. The provided preliminary utility plan depicts an 8-inch sewer main extension through the new residential access street providing side sewer stubs to all proposed lots. i. The sewer main extension shall extend to the extreme northern property line adjacent to NE 8th Street. Or extend sewer main on the access road within Tract A for future sewer connection of adjacent property (i.e., 5735 NE 8th St of parcel #1123059034). ii. All the proposed side sewer and sewer stubs shall have a minimum 2% slope per RMC 4-6-040 and City of Renton standard details. 2. A 15-foot easement is required for any public sewer main located outside of the public right- of-way. 3. The development is subject to a wastewater system development charge (SDC) fee. SDC fee for sewer is based on the size of the new domestic water to serve the project. Current fees can be found in the 2025 Development Fees Document on the City’s website. Fees will be charged based on the rate at the time of construction permit issuance. a. The current sewer fee for a 1-inch meter is $4,025.00 per meter. b. Final determination of applicable fees will be made after the water meter size has been determined. c. The full fee schedule can be found at: https://edocs.rentonwa.gov/Documents/Browse.aspx?id=8217302&dbid=1&repo= CityofRenton 4. The development is located within the East Renton Interceptor Special Assessment District (SAD) and is subject to SAD Fees as part of the development. This SAD does not accrue interest and is assessed at $316.80 per residential unit. SURFACE WATER COMMENTS 1. A preliminary TIR prepared on October 20, 2023, and revised on December 2nd, 2024, was submitted by Sazei Design Group, LLC with the Land Use Application. The site falls within the Flow Control Duration Standard Matching Forested Site Conditions. The property is bisected by two drainage basins, Lower Cedar River and May Creek; the majority of the site falls within the May Creek drainage basin while a small portion along the southern property line falls within the Cedar River drainage basin. The report is based on a full drainage review and Core Requirements 1 through 9 and the six Special Requirements have been discussed in the TIR. a. Discharge at the Natural Location, RSWDM Core Requirement #1: All storm water runoff and surface water from a project must be discharged at the natural location so as not to be diverted onto or away from downstream properties. i. The revised TIR depicts that the project is analyzed and mitigated in two sub-basins (Sub-basin 1 to the south and Sub-basin 2 to the west) to meet Core Requirement #1 above. The TIR depicts that Sub-basin 1 to the south will discharge to the existing conveyance system on Pascoe Pl NE within Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 Lower Cedar River basin, and the Sub-basin 2 to the west will discharges to the north within May Creek basin. Stuff concurs with this preliminary basin discharge per provided survey information and site conditions. b. Offsite Analysis, RSWDM Core Requirement #2: All proposed projects must submit an offsite analysis report that assesses potential offsite drainage and water quality impacts associated with development of the project site. The preliminary TIR submittal includes a Level 1 Downstream Analysis. i. A level 1 offsite analysis was performed on October 10, 2023, for both the drainage basins (Lower Cedar River and May Creek), and no drainage or water quality issues were identified. Stuff concurs with this preliminary analysis and will further review during the civil construction permit application. c. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or water quality vault shall be designed in accordance with the RSWDM that is current at the time of civil construction permit application. The project proposes a detention facility to meet the flow control requirement. i. A detention vault and associated pumps were proposed for Sub-basin 1 to meet the flow control requirement. For Sub-basin 2, the TIR depicts that detention facility is not required since the drainage basin will generate less than 0.15-cfs increase in the developed 100-year peak flows compared to the existing forested site conditions. These analyses are deemed acceptable and will be further reviewed during the civil construction permit application. ii. The proposed detention vault and stormwater pumps for Sub-basin 1 shall be privately owned, maintained, and operated. d. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. The proposal includes a conveyance system analysis section. i. Section 5 of the TIR indicates that the proposed conveyance system will have the capacity to convey 100-year peak flow, which is conceptually acceptable, and will be further reviewed during civil construction permit application. e. Construction Stormwater Pollution Prevention Plan (CSWPPP), Core Requirement #5 i. The CSWPPP shall be provided as part of the civil construction permit application. f. Maintenance and Operations, Core Requirement #6 i. A maintenance and operation manual has been provided with the TIR, which will be further reviewed during civil construction permit application. g. Water Quality, RSWDM Core Requirement #8: All projects that add more than 5,000 square feet of pollution generating impervious surface (PGIS) that is not fully dispersed and less than 0.75 acre of pollution generating pervious surface that is not fully dispersed require water quality. i. The TIR indicates that the PGIS surfaces will be treated with a Contech Filterra upstream of the detention vault for Sub-basin 1. Sub-basin 2 is exempted for water quality treatment requirement since less than 5,000 square feet of new and replaced PGIS is added. This is conceptually Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 acceptable and will be further reviewed as part of civil construction permit application. h. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. i. A geotechnical report dated February 8, 2024, completed by Ages Engineering, and a soil infiltration testing report dated October 20th, 2024, prepared by a licensed civil engineer were provided with the Land Use Application. Geotechnical recommendations presented in this report do not support the use of infiltration in Sub-basin 1 to the south due to underlying dense soils and shallow perched groundwater. The provided infiltration testing report attached in the TIR indicates a design infiltration rate of 1.22 in/hr to be used for sizing infiltration facilities in Sub-basin 2. ii. The TIR indicates that onsite BMPs of permeable pavement and perforated pipe connections will be used for on Sub-basin 1, and partial infiltration and permeable pavement will be applied for Sub-basin 2. Staff concurs with this assessment, and will further review during civil construction permit application. 2. Erosion control measures to meet the City requirements shall be provided. a. An erosion control plan was provided with the land use submittal, and will be reviewed during the civil construction permit application. 3. The development is subject to a surface water system development charge (SDC) fees. Fees will be charged based on the rate at the time of construction permit issuance. a. The current SDC fee for a single-family residence is $2,350 per lot. b. The full fee schedule can be found at: https://edocs.rentonwa.gov/Documents/DocView.aspx?id=11713108&dbid=0&repo=C ityofRenton. TRANSPORATION COMMENTS 1. Per City code 4-6-060 frontage improvements are required for new construction in excess of $175,000. The proposed development fronts Pasco Pl NE along a portion of the southern property line and private property on all other sides. • Pascoe Pl NE is classified as a Residential Access Street with an existing right-of-way (ROW) width of 53 feet per the King County Assessors Map. To meet the City’s complete street standards for a Residential Access Street, a minimum ROW width of 53 feet is required for a full street, and a minimum 35 feet for a half-street. The minimum section for a half street per RMC 4-6-060 consists of a minimum 20-foot paved road, a 0.5-foot curb, an 8-foot planting strip, a 5-foot sidewalk, street trees and storm drainage improvements. The extension of Pasco PL NE shall be made perpendicular and along the subject property’s eastern property line. However, the existing alignment of Pasco PL NE south of the subject property is not perpendicular, therefore, a horizontal shall be provided to transition the existing road centerline to that of the new half street such that the existing western curbline is maintained. Dedication along the transition is subject to final survey and decrease to the 35-foot minimum for a half street. i. The street section of Pascoe Pl NE as shown on the preliminary site plan is conceptually acceptable. ii. Plans submitted with civil construction permit shall demonstrate how curve geometrics are compliant with RMC 4-6-060.F.7.c for residential access streets. Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 • NE 8th St is private property (parcel 1123059129), however, the City plans for this street to become a public Residential Access street. To meet the City’s complete street standards for a Residential Access Street, a minimum ROW width of 53 feet is required for a full street, and a minimum 35 feet for a half-street. The minimum section for a half street per RMC 4-6-060 consists of a minimum 20-foot paved road, a 0.5-foot curb, an 8-foot planting strip, a 5-foot sidewalk, street trees and storm drainage improvements. Dedication of approximately 13.5 feet would be required to install half street improvements. i. However, the existing parcel, 1123059129, is 30 feet in width with the northern property line being the future ROW centerline for NE 8th St and there is an existing curbline to the east, set approximately 26 feet south of this northern property line. Therefore, the half street section, as taken from parcel 1123059129 northern property line, shall consist of an approximate 26-foot paved road, a 0.5-foot curb, an 8-foot landscape strip, a 5-foot sidewalk, street trees and storm drainage improvements. Dedication of approximately 8.5 feet is required. Additionally, given that parcel 1123059129 being privately owned and there is an existing access easement over said parcel, City staff will support a modification to install a reduced half street section along the subject property’s northern property line consisting of an approximate 3.5-foot landscape strip and 5 foot sidewalk. The modification is intended to be temporary in nature, such that when dedication of parcel 1123059129 occurs, the remaining half street improvements may be installed. 1. The applicant submitted a modification request consistent with the above listed improvements. Staff has reviewed the modification and recommends approval. 2. The preliminary site plan depicts the sidewalks and planter strip per the modification discussed above, which is conceptually acceptable. However, the preliminary plan on Sheet 4 indicates a 20-foot width of HMA pavement on NE 8th street fronting the project site pending on the approval from the current owner of parcel 1123059129. This agreement shall be added as a condition of approval for the land use permit. ii. Due to Pascoe Pl NE connecting to NE 8th St (a private street), an emergency access gate shall be installed. This gate shall restrict access to NE 8th St for all proposed new residences except Lot 4, while allowing emergency vehicles to pass through. 1. The applicant shall demonstrate compliance with the above statement prior to civil construction permit application. Final location of the gate will be reviewed and needs to be approved by city planning and development engineering during civil construction permit application. 2. An emergency access gate may not be required if agreed by all beneficiaries of the access easement on the private street of NE 8th St. 2. Refer to City code 4-4-080 regarding driveway regulations. • A minimum separation of 5 feet is required between driveway and the property line. • Maximum driveway slopes shall not exceed 8%. Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 • Driveway width shall not exceed thirty feet exclusive of the radii or the returns of the taper section. 3. For dead end streets that exceed 150-feet in length an approved turnaround per RMC 4-6-060 is required. Dead end access roadways more than 300-feet long will require a full 90-foot cul-de- sac. i. An emergency access easement or ROW dedication is required from the property owner of the eastern and the northern parcels (#1123059035 and #1123059129) to accommodate the proposed hammerhead turnaround on NE 8th Street. Otherwise, a hammerhead turnaround needs to be added within the project site to meet the dead-end turnaround requirement. 1. Even a preliminary agreement email from the property owner of parcel # 1123059035 for the access easement is provided as part of the land use application, this easement approval from the owner of the property shall be added as a condition of approval for the land use permit. 2. The existing access easement on the northern parcel (#1123059129) needs to be updated/revised to allow the emergency access for Renton Regional Fire Authority. This easement approval from the owner of the northern parcel shall be added as a condition of approval for the land use permit. 4. Undergrounding of all existing and new utilities is required on all frontages per RMC 4-6-090. 5. Street lighting is required for a project that consists of more than 4 residential units. See RMC 4-6-060 for street lighting requirements. • The site plan depicts conceptual locations of light poles. A complete lighting plan including photometrics shall be provided at the time of civil construction permit application. 6. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Trench Restoration and Street Overlay Requirements. 7. The development is subject to transportation impact fees. Fees will be charged based on the rate at the time of building permit issuance. • The 2025 transportation impact fee for a single-family home is $11,485.67. • The full fee schedule can be found at: https://edocs.rentonwa.gov/Documents/DocView.aspx?id=11713108&dbid=0&repo=C ityofRenton GENERAL COMMENTS 1. If frontage improvements are required, all existing and proposed utility lines (i.e. electrical, phone, and cable services, etc.) along property frontage or within the site must be underground as outlined in RMC 4-6-090 – UTILITY LINES - UNDERGROUND INSTALLATION. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Adequate separation between utilities as well as other features shall be provided in accordance with code requirements. a. 7-ft minimum horizontal and 1-ft vertical separation between storm and other utilities is required with the exception of water lines which require 10-ft horizontal and 1.5-ft vertical. b. The stormwater line should be minimum 5 feet away from any other structure or wall or building. Docusign Envelope ID: 6A37E369-83A5-4681-BBCF-E252AC941B41 c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building. 3.
