A 0.5’ curb and a 5’ concrete sidewalk directly behind the curb exist along each side of the pavement. The existing right of way width for N. 30th Street is approximately 60’ for the majority of the frontage per the King County Assessor’s Map. The existing right of width for N. 30th Street adjacent to a portion of the eastern frontage is 72’ per the King County Assessor’s Map. WATER COMMENTS 1. The utility plan shows one new fire hydrant on private property. The hydrant is served off of the new 16” water main that will be installed in the shared driveway to serve the new Kennydale Reservoir north of the Fire Station. All fire hydrants on private property shall be located in a public utility easement. 2. A fire sprinkler stub with a double detector check valve assembly (DDCVA) in an exterior underground vault within private property per COR Std. Plan 360.2 is required. The DDCVA may be installed in the building if it meets the conditions as shown on COR Std. Plan 360.5 for the installation of a DDCVA inside a building. The utility plan shows a 4” fire line connected to the new 16” water main that will serve the new Kennydale Reservoir. The DDCVA is shown in a sprinkler riser room in the rear of the building in the submitted architectural plans. A post indicator valve (PIV) per City standards is required on the fire line. The fire sprinkler stub and appurtenance shall be sized by a registered fire sprinkler designer / contractor. A Fire Department Connection (FDC) is provided at the corner of the shared driveway and rear parking lot. The FDC is within 50’ from the proposed fire hydrant. Per COR Std. Plan 360.5, the DDCVA shall be within 50’ of the public water main easement boundary or right of way line. The DDCVA as shown is 96’ from the water main. This is not in compliance with COR Std. Plan 360.5. The plans submitted for construction permit review shall be revised to show compliance. 3. The utility plan shows a 2” domestic water service and meter for domestic water use. The service is connected to the new 16” water main that will serve the new Kennydale Reservoir. The plan shows the meter on private property. The meter shall be located in a public utility easement. A reduced pressure backflow assembly (RPBA) shall be installed behind the meter within private property. The RPBA shall be installed in an above ground heated enclosure per COR Std. Plan 350.2. The RPBA may be located inside the building if a drainage outlet for the relief valve is provided and the location is approved by the City Plan Reviewer and City Water Utility Department. The submitted architectural plans do not show a location for the RPBA in the building. Fire Station 15 – LUA17-00632 Page 3 of 8 October 23, 2017 K:\Projects\2017\PR17000490_FIRE STATION 15\LUA17-000632\08.Review Comments - Drafts\C_Civil Advisory Notes LU17000632_171023_v1.docx 4. The utility plan shows the existing 3/4” water meter being relocated and reused for irrigation service. The plan shows the meter located on private property in the garage drive aisle. This meter should be located outside of the drive aisle and contained in a public utility easement if on private property. A double check valve assembly (DCVA) on private property is required behind the meter per COR Std. Plan 340.8. 5. Water system improvements shall be designed in accordance with Appendix J of the City’s 2012 Water System Plan. Adequate horizontal and vertical separation between new water mains and other existing and proposed utilities (sewer lines, storm drains, gas lines, power and communication ducts) shall be provided for the operation and maintenance of the water main. Retaining walls, rockeries, or similar structures cannot be installed over the water main unless the water main is installed inside of a steel casing. 6. The site is located within Zone 2 of the City’s Aquifer Protection Area. 7. Per RMC 4-1-180B-2b, City-owned properties are exempt from all system development charges. SEWER COMMENTS 1. The utility plan shows a new 6” side sewer connecting to the existing 8” sewer main along the eastern property frontage. The new side sewer shall run at a slope of at least 2% from the building to the main. 2. The utility plan shows a new oil/water separator located outside of the building in the garage drive aisle. All wastewater from the garage area shall be routed through this oil/water separator. A specification for the oil/water separator should be included with the construction plans. The oil/water separator shall be approved by the City Plan Reviewer and City Wastewater Utility Department prior to construction permit issuance. 3. A 10’ utility easement will be required for the existing sewer main along the eastern property line. 4. Per RMC 4-1-180B-2b, City-owned properties are exempt from all system development charges. STORM DRAINAGE COMMENTS 1. A drainage plan and Technical Information Report (TIR) prepared by LPD Engineering dated September 22, 2017 were submitted to the City as part of the site plan submittal. The site is located in the City’s Peak Rate Flow Control Standard (Existing Site Conditions). The site is located in the East Lake Washington drainage basin. The TIR was completed in accordance with the standards found in the 2017 Renton Surface Water Design Manual (RSWDM). All nine core and six special requirements were addressed. Fire Station 15 – LUA17-00632 Page 4 of 8 October 23, 2017 K:\Projects\2017\PR17000490_FIRE STATION 15\LUA17-000632\08.Review Comments - Drafts\C_Civil Advisory Notes LU17000632_171023_v1.docx The project proposes to route the majority of the on-site impervious surfaces to a Brentwood Stormtank Detention system located between the Fire Station and N. 30th Street to meet Core Requirement #3 – Flow Control Facilities. A flow control riser tee is located downstream of the detention system. The TIR shows that the 2-yr and 100-year peak runoff rates are matched but the 10-year runoff rate is not matched. Per Section 1.2.3.1 of the 2017 RSWDM, the developed peak discharge rates must match the existing peak discharge rates for the 2-yr, 10-yr, and 100-yr return periods. The project will be required to show compliance with this requirement at the time of construction permit review to satisfy Core Requirement #3. The Stormtank system, Stormfilter or other water quality treatment facility, bioretention facility, pervious pavement, catch basin, and stormwater conveyance on the site will be private maintained. A recorded stormwater covenant for maintenance of the stormwater facilities and on-site BMPs will be required. The Stormtank system as proposed does not meet the requirements for a detention tank per Section 5.1.2 or a detention vault per Section 5.1.3. The revised TIR and construction plans shall clearly show how the Stormtank system meets all of the requirements of either a detention tank or detention vault. If not all of the requirements can be met, a stormwater adjustment per Section 1.4 would have to be submitted and approved prior to issuance of the construction permit. City staff would not support an adjustment to omit requirements related to access, maintenance, height, sediment storage, or ventilation. A simple conveyance calculation was submitted in the TIR. The engineer shows that the pipe segment that discharges stormwater from the site to the City’s piped stormwater conveyance system can convey the 25-year flow from the entire site if it were impervious. This conveyance calculation is shown to demonstrate compliance with Core Requirement #4 – Conveyance System. As the Fire Station will require a commercial building permit, Enhanced Basic Water Quality treatment is required unless such treatment is waived or reduced by the area- specific exceptions found in Section 1.2.8.1 to satisfy Core Requirement #8 – Water Quality Facilities. According to the TIR, the project proposes approximately 8,965 square feet of pollution generating impervious surface (PGIS). The project proposes to treat the PGIS from the shared driveway and the driveway from the Fire Station to N. 30th Street using a Stormfilter system. A Stormfilter system is an acceptable treatment option for Basic Water Quality treatment however it is not acceptable as a standalone option for Enhanced Basic Water Quality treatment. The plans and TIR should be updated to show compliance the Enhanced Basic Water Quality treatment standard by providing an Enhanced Basic Water Treatment facility per Section 6.1.2 unless exempted per Section 1.2.8.1 for all PGIS on the site. PGIS with permeable pavement may be exempted for the water quality standards if the Soil Treatment Exemption found in Section 1.2.8 is met for the soils underneath the pavement. If this exemption is pursued a letter from a Fire Station 15 – LUA17-00632 Page 5 of 8 October 23, 2017 K:\Projects\2017\PR17000490_FIRE STATION 15\LUA17-000632\08.Review Comments - Drafts\C_Civil Advisory Notes LU17000632_171023_v1.docx geotechnical engineer will be required stating that all of the criteria are met. Permeable pavement alone is not a water quality treatment facility. The TIR and plans do not show treatment of the drive apron on the north side of the building. This area needs to be treated by an acceptable water quality facility. The areas on the southern end of the shared driveway and the driveway between the Fire Station and N. 30th Street that are not being treated by a water quality treatment facility are less than 5,000 square feet in area. The project is required to implement on-site BMPs per Section 1.2.9 to satisfy Core Requirement #9 – On-Site BMPs. On-site BMPs need to be evaluated in order of preference as required per Section 1.2.9.2.2. This evaluation should be included in the updated TIR that is submitted for construction permit review. The TIR did not have infiltration testing results from the geotechnical engineer when designing the on-site BMPs proposed on the plan. The TIR determined that full dispersion and full infiltration are infeasible. The updated TIR should clearly explain how full infiltration is infeasible per Section 5.2. The TIR and plans propose to use bioretention and permeable pavement for on-site BMPs. The updated TIR and plans must clearly show how each of these BMPs are implemented to the maximum extent feasible. After implementation of those BMPs to the maximum extent feasible, the project must ensure that the minimum BMP implementation per Section 1.2.9.2.2 #5 is met. For projects that will result in an impervious surface coverage greater than 65% of the buildable portion of the site / lot, on-site BMPs must be applied to 20% of the target impervious surfaces or to an impervious area equal to at least 10% of the site/lot, whichever is less. The updated TIR and plans should show compliance with all biorentenion design standards per Section 2.6 and permeable pavement design standards per Section 2.7. Bioretention with underdrains is not allowed for Core Requirement #9 unless approved by a stormwater adjustment. 2. The drainage plan shows that the existing N. 30th Street flowline adjacent to the site will remain in the same location. The storm drainage from the project will tie into the existing 12” piped conveyance system along this flowline. 3. A geotechnical report evaluating site soil conditions was prepared by HWA Geosciences dated August 31, 2017. Per the geotechnical report, the site is underlain by recessional outwash soils. The outwash soils were classified as loose to medium dense. The report notes that there is about 5-7’ of sandy silt soils with a high percentage of fines were encountered. The report recommends that these soils are over-excavated and backfilled with free-draining granular material such as pea gravel where pervious pavement and the bioretention pond are proposed. A pilot infiltration test (PIT) was performed on the site in the location of the proposed bioretention pond. The PIT was performed at a depth of 7’. The report notes that Fire Station 15 – LUA17-00632 Page 6 of 8 October 23, 2017 K:\Projects\2017\PR17000490_FIRE STATION 15\LUA17-000632\08.Review Comments - Drafts\C_Civil Advisory Notes LU17000632_171023_v1.docx cleaner sands are encountered at approximately 7’ below the surface. The two areas were excavated to a depth of approximately 3’ below grade. Based on the test results, the geotechnical engineer concluded that a long-term infiltration rate of 1.1 in/hour be used for design assuming the upper 7 feet of soil (silty material) was removed. 5. Per RMC 4-1-180B-2b, City-owned properties are exempt from all system development charges. TRANSPORTATION/STREET COMMENTS 1. Transportation impact fees do not apply to this project. 2. N. 30th Street is classified as a minor arterial. Per RMC 4-6-060, the minimum right of way width for a minor arterial with four lanes is 91’. The paved roadway section is 54’ consisting of 4 – 11’ travel lanes and 2 – 5’ bike lanes. A 0.5’ curb, 8’ planter, 8’ sidewalk, and 2’ clear from the back of sidewalk are required along each side of the roadway. The King County Assessor’s Map shows a current right of way width of approximately 60’ to 72’ for N. 30th Street adjacent to the site. A right of way dedication of approximately 15.5’ would be required along the project frontage. 3. The applicant submitted a street modification request dated September 28, 2017 with the land use application. The street modification request is to modify the minor arterial street section per RMC 4-6-060 to a modified minor arterial street section. Specifically the applicant requests a street section that keeps the current curb line in its existing location along the northern frontage of N. 30th Street adjacent to the site with an 8’ planter, 8’ sidewalk, and 2’ clear from back of sidewalk. The applicant proposes a right of way dedication of approximately 11’ along the project’s N. 30th Street frontage to accommodate the modified minor arterial street section improvements. The applicant also requested a waiver of installation of the frontage improvements. The applicant proposes to keep the existing sidewalk in its current location. City staff is recommending approval of the applicant’s street modification request. Please see the Street and Driveway Modification Criteria and Analysis for a complete summary of the request, staff analysis, and staff recommendation. City staff is not recommending approval of the waiver of installation of frontage improvements. City staff recommends that approximately 11’ of right of way be dedicated along the project’s N. 30th Street frontage and frontage improvements in accordance with the modified minor arterial street section be installed. The construction plans submitted for construction permit review should be updated to show these improvements. The applicant also proposes to modify the maximum driveway width from 30’ to 36’ for the driveway from the Fire Station garage to N. 30th Street. City staff is recommending approval of the applicant’s driveway modification request. Please see the Street and Driveway Modification Criteria and Analysis for a complete summary of the request, staff analysis, and staff recommendation. Fire Station 15 – LUA17-00632 Page 7 of 8 October 23, 2017 K:\Projects\2017\PR17000490_FIRE STATION 15\LUA17-000632\08.Review Comments - Drafts\C_Civil Advisory Notes LU17000632_171023_v1.docx 4. A shared driveway is proposed along the western property frontage to provide access to the rear of the Fire Station and to the Kennydale Reservoir. The proposed shared driveway meets all design standards found in RMC 4-6-060. The shared driveway is approximately 197’ in length (before right of way dedication), has a pavement width of 16’ – 24’, and a grade of less than 15%. Where feasible, drainage from the shared driveway will be captured by the site’s conveyance system and routed to the onsite stormwater detention system. 5. The proposed driveway curb cut for the shared driveway is 20’ in width and is located 5’ from the adjacent property line. This meets the driveway width standards found in RMC 4-4-080. City staff recommends approval of a modification to the maximum driveway width to 36’ for the driveway from the Fire Station garage to N. 30th Street. Please see the Street and Driveway Modification Criteria and Analysis for a complete summary of the request, staff analysis, and staff recommendation. 6. A Trip Generation Memo prepared by Transpo Group dated July 11, 2017 was submitted to the City as part of the site plan submittal. The Institute of Transportation Engineers (ITE) Trip Generation Manual 9th Edition does not publish trip generation rates for a fire station. The memo looked at trip generation based upon staffing information from the Renton Regional Fire Authority (RRFA), estimates on visitors and miscellaneous trips to the site, and emergency call information from the RRFA. The memo notes that the Fire Station will have the capacity for 3 employees. The employees will work 24-hour shifts with shift change occurring daily at 8:00 AM per the RRFA. Thus the memo assumes the Fire Station will generate a total of 6 trips per day (one inbound and one outbound) for the employees in the peak AM hours (6:00 – 9:00). The memo estimates visitors and miscellaneous trips to the Fire Station. There is assumed to be 20 non-employee trips to the site (10 entering and 10 existing). 20 percent of these trips are expected to occur in the AM and PM peak hours. Thus, 4 total trips are expected in each the AM and PM peak hours. The memo also estimates that 20 emergency vehicle trips are expected to occur on an average weekday. This is based on information provided by the RRFA regarding the anticipated response calls that will be fielded by this station. 20 percent of these trips are expected to occur in the AM and PM peak hours. Thus 4 total trips are expected in each of the AM and PM peak hours. The memo concludes that Fire Station 15 will generate 14 trips in the AM peak hours (6:00 – 9:00) and 8 trips in the PM peak hours (3:00 – 6:00). The City requires a Traffic Impact Analysis if new vehicular traffic exceeding 20 vehicles per hour in either the AM or PM peak hours is generated by a development. As this project does not meet that threshold, no further review is needed. City staff is in agreement with the findings of this memo and will not require any further studies.

Street lighting per City standards is required along the N. 30th Street frontage. A street lighting analysis and plan shall be submitted with the construction permit. 8. Advanced warning signs for the Fire Station along N. 30th Street per MUTCD standards are required. 9. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Restoration and Overlay requirements. GENERAL COMMENTS 1. All new utility lines (i.e. electrical, phone, and cable services, etc.) within the site must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Retaining walls that are 4’ or taller from bottom of footing and stormwater detention vaults will require a separate building permit.
