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: A Geotechnical Report, prepared by Stantec, dated September 18, 2019 (Exhibit 5) was submitted with the project application materials. According to the submitted geotech report, the UST removal and replacement work would require excavations extending to depths of 15 feet below ground surface. Based on recent UST installations at other 7-Eleven facilities, it is expected the replacement tank excavation would be backfilled with pea gravel half-way up the new tanks. Imported or suitable onsite structural fill would likely be placed by the contractor up to subgrade elevations and compacted by the contractor with finish grade achieved by a minimum of 6 inches concrete. The report included recommendations regarding shoring, backfilling and compaction, and paving. It is anticipated that the City’s currently adopted erosion control, construction, and drainage regulations would adequately mitigate for any impacts that could result from the proposed tank removal; therefore, no further mitigation is recommended. Mitigation Measures: None recommended Nexus: N/A 2. Water a. Storm Water Impacts: The applicant submitted a Technical Information Report (TIR), prepared by Barghausen Consulting Engineers, Inc., dated October 11, 2019 (Exhibit 4). According to the submitted TIR, the City of Renton Department of Community & Economic Development 7-Eleven UST Replacement Staff Report to the Environmental Review Committee LUA20-000014, ECF Report of March 2, 2020 Page 3 of 3 ERC_7-11 UST Replacement_FINAL existing site hydrology exhibits sheet flow from the east to the west portion of the site. Existing storm structures consisted of catch basins and conveyance pipes collect runoff and route it to the public storm sewer that runs along 116th Avenue S.E. The proposed drainage patterns would largely remain the same with the exception of the runoff from the proposed fueling pad. The fueling area would be constructed as a containment pad with an impervious surface and would route runoff to a proposed oil control structure before it enters the public sanitary network. Runoff from all other impervious surfaces other than the fueling slab, would be conveyed to the storm network through existing drainage and conveyance facilities. The improvements would be graded to exhibit such drainage behavior with the usage of concrete and asphalt swales. The total land disturbing area would total 4,217 square feet. However, 1,925 square feet would be considered Replaced Impervious Surface. As the project proposed involves less than 5,000 square feet of new plus replaced impervious surfaces as well as less than 3/4 acres of new pervious surface, the project proposal would be exempt from implementing any flow control systems and water quality treatment facilities; therefore no further mitigation is recommended. Mitigation Measures: None recommended Nexus: N/A 3. Environmental Health Impacts: According to the submitted geotech report (Exhibit 5), a review of the Washington State Department of Ecology (Ecology) Regulated USTs database was conducted, one of the three existing USTs had been in temporary closure status. Putting a UST into temporary closure indicates that a UST had failed tank integrity testing and, as a result, the potential for leakage from the tank (normally at the spill bucket or a piping connection at the UST; periodically the UST itself) can occur. As such, this project involved environmental sampling. Two 30-foot-deep soil borings were drilled on the project site. Boring GT-1 was located immediately south of the south end of the existing USTs and very close to the front of the convenience store (in between the USTs and the convenience store). Boring GT-2 was located immediately northwest of the existing USTs and west of the dispenser area (between the dispenser area and the small retaining wall near the west property line). The soil borings were drilled using a truck-mounted Mobile B-58 drill rig. In addition to the soil samples, one groundwater sample was collected from near the bottom of the GT-2 boring. Results of chemical analyses on soil samples collected during recent drilling did not reveal fuel impacts; however, the contractor should be ready to handle any fuel-impacted soil that may be encountered during excavation. If any fuel-impacted soils are encountered, clean-up would be required to comply with the Washington State Department of Ecology Standards; therefore no further mitigation is recommended. Mitigation Measures: None recommended Nexus: N/A E. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers.

The proposed utility plans indicate a connection to the sanitary sewer system. Applicant shall provide a copy of the approved sewer plan from Soos Creek Water and Sewer District prior to approval of the Civil Construction Permit. SURFACE WATER 1. A geotechnical report dated September 18, 2019, completed by Stantec Consulting Services Inc., was provided with the Land Use Application. The report discusses the soil and groundwater characteristics of the site and provides recommendations for project design and construction. An investigation of potential contaminated soils was performed in two test pits with total petroleum hydrocarbons less than the WA Department of Ecology Model Toxic Control Act Method A Cleanup Levels. a. Quantity and location of samples shall be as required by WA DOE. Two samples were tested, the Department of Ecology document ‘Guidance for Site Checks and Site Assessments for Underground Storage Tanks’ indicates a minimum of three samples shall be taken with one (1) additional sample under each tank when multiple tanks less than 20,000 gallons are removed from the same excavation. 2. A TIR by Barghausen Consulting Engineers, Inc. dated October 11, 2019, is included with the land use application. Based on the City of Renton’s flow control map, the site falls within the City’s Flow Control Duration Standard Matching Forested Site Conditions and is within the Soos Creek Drainage Basin. The project is subject to a Full Drainage review in accordance with the 2017 RSWDM. The TIR discusses all 9 core requirements and 5 of the 6 special requirements. a. Offsite Analysis, RSWDM Core Requirement #2: If the project adds less than 2,000 square feet of new impervious surface and less than ¾ acre of new pervious surface and does not construct or modify a drainage pipe/ditch and does not contain or lie adjacent to a landslide, steep slope or erosion hazard area then the project is exempt from an offsite analysis. The TIR and proposal indicate the project meets the exemption criteria. Figure 9 of the TIR indicates that there is 4,217 SF of impervious surface, however, 2,292 SF is for the sole purpose of installing utilities on underground infrastructure therefore only 1,925 SF is considered replaced impervious surface. i. Figure 9 shall be updated to include the impervious surface being replaced for the new sewer utility. However, as the impervious surface is being replaced for the sole purpose of installing underground utilities it shall not count toward the total replaced impervious surface. b. Flow Control, RSWDM Core Requirement #3: If there is less than 5,000 square feet of new plus replaced impervious surface and less than ¾ of new pervious surface the 7 Eleven UST replacement – LUA20-000014 Page 3 of 7 February 10, 2020 project is exempt from a flow control facility. The TIR and proposal indicate the project meets the exemption criteria. c. 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 does not indicate the addition or modification of a conveyance system nor does it indicate a change in flow characteristics for the existing conveyance systems. d. Erosion and Sediment Control, RSWDM Core Requirement #5: All proposed projects that will disturb the site must provide erosion and sediment controls. A SWPP and ESC were submit with the land use application. e. Maintenance and Operations, RSWDM Core Requirement #6: Maintenance and operation of all drainage facilities is either private or public and must be maintained in accordance with the maintenance standards in Appendix A of the RSWDM. The TIR and proposed utility plan do not indicate the installation of any new drainage features. However, the TIR includes an operation manual for the new oil water separator that is draining to the sanitary sewer system. f. Financial Guarantees and Liability, RSWDM Core Requirement #7: A construction surety device, as calculated from the bond quantity worksheet, and insurance is required for civil construction. The TIR indicates that the bond quantity worksheet will be provided with a future submittal. i. A bond quantity worksheet will be required to be submit with the civil construction permit application. g. Water Quality Facilities, RSWDM Core Requirement #8: All proposed projects must provide water quality facilities to treat runoff from pollution generating impervious surface. The project proposes to construct less than 5,000 square feet of new and replaced pollution generating impervious surface and less than ¾ acre of new pollution generating pervious surface; therefore the proposal is exempt from a water quality as indicated in TIR. h. On Site BMPS, RSWDM Core Requirement #9: All proposed projects must provide on site BMPs to the maximum extent feasible. The project proposes less than 2,000 square feet of new plus replaced impervious surface and less than 7000 square feet of land disturbing activity; therefore the proposal is exempt from on site BMPs. i. Special requirements 1-3, 6: Based on the project proposed, these requirements are not applicable. i. Although not applicable to the project special requirement 6 shall be addressed in the TIR. j. Special requirement 4, Source Controls: A proposed project subject to a site development permit shall apply applicable source controls in accordance with the King County Stormwater Pollution Prevention Manual and RMC title IV. The TIR indicates that the project is exempt, however, section 4.3 identifies implementation of A-17 Fueling Operations. As a civil construction permit is required, compliance with special requirement 4 is required. k. Special requirement 5, Oil Control: The proposal is exempt as it redevelops a high use site with improvements less than 100,000 and results I less than 5,000 SF of new plus replaced pollution generating impervious surface. The TIR indicates that the project shall comply with the special requirement; however, it appears that special requirement 4 and 5 were interchanged on accident. TIR shall be updated accordingly. 7 Eleven UST replacement – LUA20-000014 Page 4 of 7 February 10, 2020 l. Section 7 of the TIR lists other anticipated permits. Applicant shall verify requirements of WA DOE for permitting underground storage tanks. 3. The current Surface Water Standard Plans shall be used in all drainage plan submittals. The current City of Renton Standard Details is available online on the City of Renton website. 4. The 2020 Surface water system development fee is $0.76 per square foot of new impervious surface, but no less than $1,800.00. This is payable prior to issuance of the construction permit. This fee is subject to change based on the calendar year the construction permit is issued. TRANSPORTATION 1. Frontage improvements are required for all new construction with valuation in excess of $150,000. The proposed project fronts SE 168th St along the north property line and 116th Ave SE along the east property line. Based on information submit with the land use application the project would be exempt from street frontage improvements as it results in less than $150,000 valuation. However, if additional improvements are required that result in an increase in the valuation, then the following improvements will be required. a. SE 168th St is classified as a Collector Arterial street with an existing right-of-way (ROW) width of approximately 60-feet as measured using the King County Assessor’s Map. To meet the City’s complete street standards for Collector Arterial streets, minimum ROW is 83 feet. Per City code 4-6-060 half of street improvements shall include a minimum pavement width of 46 feet (23 feet from centerline), 8 feet wide parking lane both sides, 0.5 feet wide curbs, 8 feet wide planting strip, 8 feet wide sidewalk and 2 feet clear space. i. However, the transportation department has determined that the existing curb- to-curb width of approximately 44 feet is sufficient for planned use on SE 168th ST. Therefore, a dedication of approximately 10.5 feet will be required pending field survey. b. 116th Ave S is classified as a Minor Arterial street with an existing ROW width of approximately 60 feet according to the King County Assessor’s Map. To meet the City’s complete street standards for 4-lane Minor Arterial streets, minimum ROW is 91 feet. Per City code 4-6-060, half street improvements shall include a minimum pavement width of 54 feet (27 feet from centerline), 0.5 feet wide curbs, 8 feet wide planting strip, 8 feet wide sidewalk and 2 feet clear space. i. However, the project falls within the adopted Benson Hill Community Plan. ROW and street frontage requirements are shown in the cross section included in the Benson Hill Community Plan and include up to a 64-foot ROW with a 43- foot paved roadway, up to a 4.5-foot planting strip and up to a 6-foot sidewalk. Therefore, a dedication up to approximately 10 feet will be required pending field survey. 2. Street lighting improvements are not required if: 1) two (2) to four (4) units for residential 2) zero (0) to five thousand (5,000) square feet commercial 3) or zero (0) to ten thousand (10,000) square feet industrial. a. Based on information provided in application, because less than 5,000 sf of commercial space is being added, the project is exempt from street lighting upgrades. 7 Eleven UST replacement – LUA20-000014 Page 5 of 7 February 10, 2020 3. A Traffic Impact Analysis (TIA) per City standards is required if the new development will generate new vehicular traffic exceeding 20 vehicles per hour in either the AM and PM peak periods. Because the proposal does not increase the quantity of pumps, nor does it increase the size of the convenience store, staff waived submission of a trip generation memo. a. Based on information provided in application, because the proposal does not increase the quantity of pumps nor does it increase the size of the convenience store a TIA will not be required. 4. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Restoration and Overlay requirements. 5. The transportation impact fee is based on the type of land use. For Gas Station with Convenience Store, per pump, the 2020 transportation impact fee is $47,025.42. Transportation impact fees are subject to change based on the year the building permit is applied for. a. Based on information received in the application the project would be exempt from the transportation impact fee per RMC 4-1-190.I.2.b. GENERAL COMMENTS 1. All existing and proposed utility lines (i.e. electrical, phone, and cable services, etc.) along property frontage or within the site must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Maximum exposed retaining wall height is 6-ft and shall be setback a minimum of 3-ft from the right-of-way as outlined in RMC 4-4-040 – Fences, Hedges and Retaining Walls. 3. 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. c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building. 4. All civil construction permits for utility and street improvements will require separate plan submittals. All utility plans shall confirm to the Renton Drafting Standards. A licensed Civil Engineer shall prepare the civil plans. Please visit the Development Engineering Forms page for the most up-to-date plan submittal requirements: https://rentonwa.gov/cms/One.aspx?portalId=7922741&pageId=9687014. 5.
