1. Project Overview
The Renton Pavilion Market is located at 233 Burnett Avenue South in Renton, Washington. The project site is
bounded by Renton Transit Center to the north, Burnett Avenue South to the east, Logan Avenue South to the
west, and South 3rd Street to the south. The site covers parcel no. 5696000055, 5696000065, and
5696000120 per parcel records of King County, Washington. The site currently contains the Renton Pavilion
Events Center building, concrete paving parking stalls, concrete pedestrian walkways and plaza, one driveway,
and landscaping. Refer to Figure 1-1 for a vicinity map.
The project proposes minor utility and site improvements associated with the renovation of the existing
building. Site improvements include a new driveway on Burnett Avenue South, a new temporary trash
enclosure, parking lot restriping to the north of the Renton Pavilion Event Center, and a new vestibule entry on
the south side of the building. Utility improvements include installation of new grease interceptor and
associated side sewer piping.
Refer to Appendix A for the TIR Worksheet.

EXISTING CONDITIONS
Current conditions consist of the existing Renton Pavilion Events Center building, parking area, and adjacent
plaza. The site slopes from east to west at 1.0 to 5.0%.
Runoff from the site is collected via catch basins on-site and is conveyed to storm drainage infrastructure
along the western and eastern property frontages in Logan Avenue South and Burnett Avenue South. The
majority of the site’s runoff is collected via catch basins and then discharges to the existing 18-inch public
storm drain in Logan Avenue South. The eastern edge of the site’s runoff, sheet flows to catch basins located
in the Burnett Avenue South right-of-way, which are collected by a 12-in public storm drain. Both systems
eventually discharge to Cedar River.
The on-site improvements area is approximately 3,545 square feet (0.08 acres). Refer to Appendix B for an
existing conditions map. Refer to Table 1-1 for a summary of existing surfaces.

PROPOSED CONDITIONS
The site improvements consist of pedestrian pavement replacement at the building vestibule, utility trenching,
and parking lot restriping. A new concrete vehicle driveway will be constructed on Burnett Avenue South for
additional site access. The proposed site improvements will continue to maintain existing drainage pattern.
Refer to Table 1-2 for a summary of the project’s proposed surface areas.

Refer to Appendix B for a proposed conditions exhibit.
The proposed project follows the requirements of the 2022 City of Renton Surface Water Design Manual
(RSWDM). The minimum requirements for drainage review were determined using the manual and are
detailed in the following sections of this report.
2. Conditions and Requirements Summary
The proposed redevelopment project results in more than 2,000 square feet but less than 50 acres of new plus
replaced impervious surface; therefore, a “Full Drainage Review” is required per the RSWDM, Section 1.1.2.4.
The following is a summary of how the project will comply with the nine core requirements and six special
requirements.
Refer to Appendix C for minimum requirements and Appendix D for civil plans.
CORE REQUIREMENT NO. 1: DISCHARGE AT THE NATURAL LOCATION
The project will maintain the existing topography and drainage patterns of the site. Runoff from the project site
will continue to be discharged to the existing public stormwater conveyance systems in Logan Avenue South
and Burnett Avenue South. Both existing systems ultimately discharge to Cedar River. Therefore, the project
meets the discharge requirements in Section 1.2.1 of the RSWDM.
CORE REQUIREMENT NO. 2: OFF-SITE ANALYSIS
Per RSWDM, Section 1.2.2, the project does not change the rate, volume, duration, or location of discharges
to and from the project site (existing impervious surface is replaced in kind with impervious surface having
similar runoff-generating characteristics), therefore is exempt from off-site analysis.
KPFF Consulting Engineers
4
CORE REQUIREMENT NO. 3: FLOW CONTROL
Per RSWDM, Section 1.2.3, the proposed project has less than 5,000 square feet of new plus replaced
impervious surface, and less than 3/4 acres of new pervious surface. there for is exempt from flow control
requirements.
CORE REQUIREMENT NO. 4: CONVEYANCE SYSTEM
Per RSWDM, Section 1.2.4.2, the proposed project is not required to provide conveyance system analysis
since existing onsite conveyance systems will not experience a change in flow characteristics (e.g., peak flows
or volume of flows). Therefore, the proposed project need not be analyzed for conveyance capacity.
CORE REQUIREMENT NO. 5: CONSTRUCTION STORMWATER POLLUTION
PREVENTION
Temporary Erosion and Sediment Control (TESC) best management practices (BMPs) will be implemented
during construction to prevent the transport of sediment from the project site to the maximum extent
practicable. TESC BMPs are anticipated to include silt fences, straw wattles, catch basin inserts, and other
measures as necessary.
Refer to Appendix D for Civil TESC plans.
Refer to Section 8 of this report for the Construction Stormwater Pollution Prevention Plan (CSWPPP) analysis
and design.
CORE REQUIREMENT NO. 6: MAINTENANCE AND OPERATIONS
The owner is responsible for the maintenance and operations of the proposed drainage structures. Refer to
Section 9 of this report for maintenance and operations discussion.
CORE REQUIREMENT NO. 7: FINANCIAL GUARANTEES AND LIABILITY
Since the project is not proposing any drainage facilities, this requirement is not applicable.
CORE REQUIREMENT NO. 8: WATER QUALITY
Per RSWDM, the proposed project has less than 5,000 square feet of new plus replaced impervious surface
(PGIS), and less than ¾ acres of pollutant generation pervious surface (PGPS), therefore is exempt from the
water quality requirement.
CORE REQUIREMENT NO. 9: ON-SITE BMPS
Per RSWDM, all proposed projects, including redevelopment projects, must provide on-site BMPs to mitigate
the impacts of storm and surface water runoff generated by new impervious surface, new pervious surface,
existing impervious surfaces, and replaced impervious surface targeted for mitigation.
For non-subdivision projects making improvements on an individual site/lot, implementation of this requirement
shall be in accordance with the “Individual Lot BMP Requirements” in Section 1.2.9.2 of the RSWDM. On-site
BMP requirements may be satisfied through two methods: (1) application of BMPs to the maximum extent
feasible, or (2) complying with the Low Impact Development (LID) Performance Standard. The project will
provide on-site BMPs to the maximum extent feasible for the replaced impervious surfaces. Following is the
Renton Market – City of Renton
5
evaluation of feasibility and applicability of small lot BMPs for this project per Section 1.2.9.2.1 of the RSDM.
Refer to Table 2-1 for infeasibility criteria per the RSWDM.
Full Dispersion
The site cannot accommodate the required minimum native vegetated flowpath; therefore, full dispersion is
considered infeasible per Section C.2.1.1 of the RSWDM.
Full and Limited Infiltration
The project site is located within Wellhead Protection Area, Zone 1 of the Aquifer Protection Area (APA), per
City of Renton GIS maps. Per Section 1.3.6, Special Requirement No. 6, it is prohibited to provide on-site
BMPs that rely on infiltration, such as bioretention and permeable pavement. Also, per Section C2.2, this BMP
is not allowed in Zone 1 of the APA.
Rain Gardens
The project site is located within Wellhead Protection Area, Zone 1 of the APA, per City of Renton GIS maps.
This BMP is not allowed in Zone 1 of the APA per Section C2.12 of the RSWDM.
Bioretention
The project site is located within Wellhead Protection Area, Zone 1 of the APA, per City of Renton GIS maps.
Per Section 1.3.6, Special Requirement No. 6, it is prohibited to provide on-site BMPs that rely on infiltration,
such as bioretention and permeable pavement. Also, per Section C2.6, this BMP is not allowed in Zone 1 of
the APA.
Permeable Paving
The project site is located within Wellhead Protection Area, Zone 1 of the APA, per City of Renton GIS maps.
Per Section 1.3.6, Special Requirement No. 6, it is prohibited to provide on-site BMPs that rely on infiltration,
such as bioretention and permeable pavement. In addition, per Section C2.7, this BMP is not allowed in Zone
1 of the APA. For this project, the replaced impervious surface consists of replacing/patching portions of
existing conditions and matching in kind.
Basic Dispersion
The site cannot accommodate the required minimum native vegetated flowpath; therefore, basic dispersion is
considered infeasible per Section C.2.4.1 of the RSWDM.

Table 2-1: On-site BMPs Infeasibility Criteria
No. BMP Feasibility Infeasibility Criteria
1 Full Dispersion Infeasible
Section C.2.1: Full dispersion is considered infeasible and
not required for projects that cannot meet the minimum
design requirements listed below.
• Minimum Design Requirement No. 3: A native
vegetated flowpath segment of at least 100 feet in
length (25 feet for sheet flow from a nonnative
pervious surface) must be available along the flowpath
that runoff would follow upon discharge from a
dispersion device.
2 Full Infiltration Infeasible Section C2.2: This BMP is not allowed in Zone 1 of the
Aquifer Protection Area.
3 Rain Gardens Infeasible Section C2.12: This BMP is not allowed in Zone 1 of the
Aquifer Protection Area.
4 Bioretention Infeasible Section C.2.6: This BMP is not allowed in Zone 1 of the
Aquifer Protection Area.
5 Permeable Paving Infeasible Section C2.7: This BMP is not allowed in Zone 1 of the
Aquifer Protection Area.
6 Basic Dispersion Infeasible
Section C.2.4: Basic dispersion is considered infeasible
and not required for projects that cannot meet the minimum
design requirements listed below.
• Minimum Design Requirement No. 2: Each dispersion
device must discharge runoff such that it flows over a
minimum distance of vegetated area called the
“vegetated flowpath segment.” The minimum distance,
or length of the flowpath segment, is specified in the
design specifications for each device.
SPECIAL REQUIREMENT NO. 1: OTHER ADOPTED AREA -SPECIFIC
REQUIREMENTS
There are no adopted area-specific regulations for the site. Therefore, Special Requirement No. 1 is not
applicable to the project.
SPECIAL REQUIREMENT NO. 2: FLOOD HAZARD AREA DELINEATION
Per the City of Renton GIS Maps, the project does not contain and is not adjacent to a flood hazard area. Per
the FEMA Flood Map Service Center, the project site is within the “Other Flood Areas,” Zone X, with the
annotation of 500-year flood chance. Per RSWDM, flood hazard areas are composed of the 100-year
floodplain, zero-rise flood fringe, zero-rise floodway, and FEMA floodway. Since Zone X is not considered a
100-year flood hazard area, Special Requirement No. 2 is not applicable to this project.
Refer to Appendix E for the FEMA FIRM Map.
SPECIAL REQUIREMENT NO. 3: FLOOD PROTECTION FACILITIES
The project will not rely on existing or proposed flood protection facilities for protection against hazards posed
by erosion or inundation. Therefore, Special Requirement No. 3 is not applicable to this project.
Renton Market – City of Renton
7
SPECIAL REQUIREMENT NO. 4: SOURCE CONTROL
Water quality source controls applicable to this project will be applied in accordance with the King County
Stormwater Pollution Prevention Manual and Renton Municipal Code, Title IV. The proposed trash enclosure
includes roof to prevent rainwater interaction with dumpster/trash receptacles.
SPECIAL REQUIREMENT NO. 5: OIL CONTROL
The site is not considered high-use because its anticipated average daily traffic count is less than 100 vehicles
per 1,000 square feet of gross building area; therefore, Special Requirement No. 5 is not applicable.
SPECIAL REQUIREMENT NO. 6: AQUIFER PROTECTION AREA
Per the City of Renton GIS Maps, the site is located within the Wellhead Protection Area, Zone 1 of the APA.
The project does not propose any type of prohibited systems including flow control facilities, on-site BMPs that
rely on infiltration, or open channel conveyance systems.
Refer to Appendix F for the City of Renton Critical Areas Map.
3. Off-Site Analysis (N/A)
As mentioned in Section 2, Core Requirement No. 2, this project is exempt from off-site analysis. Therefore,
this section is not applicable.
4. Flow Control, Low Impact Development (LID), and Water
Quality Facility Analysis and Design (N/A)
As mentioned in the Core Requirements summary, this project is exempt from flow control and water quality
requirements. Refer to Section 2 of this report.
On-site BMP requirements may be satisfied through two methods: (1) application of BMPs to the maximum
extent feasible, or (2) complying with the Low Impact Development (LID) Performance Standard. The project is
addressing Core Requirement No. 9 through method 1, however as noted above, applicable and available
BMP's are not feasible.
5. Conveyance System Analysis and Design
As mentioned in Section 2, Core Requirement No. 4, this project is exempt from the conveyance system
analysis.
The project will replace the existing area drain adjacent the south vestibule entry with a 4-inch trench drain.
The grading has been revised to move the low point away from the doors to the Market but will continue to
collect the same area. The proposed trench drain will be connected to an existing 8-inch storm drain. The total
drainage area for the trench drain is approximately 5,720-square feet, which results in a 0.38-cfs during a 25-
year 24-hour rainfall event, and 0.44-cfs during a 100-year 24-hour rainfall event. The 4-inch trench will have a
minimum depth of 9.8-inch and will have the minimum capacity of 0.38-cfs with 9.7-inches of minimum nominal
KPFF Consulting Engineers
8
depth. The existing 8-inch storm drain at the proposed south vestibule will be routed to avoid the proposed
structural foundations. Approximately 3,500-square feet of existing roof will also be redirected to the existing 8-
inch storm drain at the south vestibule entry. The total drainage area for the proposed 8-inch storm drain is
approximately 16,855- square feet and will result in the following flow rates: 0.96-cfs during a 25-year 24-hour
rainfall event. The proposed 8-inch storm drain, sloped at 0.4%, has a full flow capacity rate of 0.99-cfs,
therefore has sufficient capacity to drain the additional roof area.
Refer to Appendix G for conveyance calculations.
6. Special Reports and Studies (N/A)
This section is not applicable to the project.
7. Other Permits
The required permits associated with the project are listed below. This report covers the requirements
pertaining to the “Civil Construction Permit” submitted to the City of Renton.

(CSWPPP) Analysis and Design
PART 8.A: EROSION AND SEDIMENT CONTROL PLAN ANALYSIS AND DESIGN
Temporary and permanent erosion and sediment control (ESC) measures will be implemented per
Appendix D, Section D.2.1, of the RSWDM.
1. Clearing Limits: Prior to any site clearing or grading, areas to remain undisturbed during project
construction shall be delineated on the project’s ESC plan and physically marked on the project site.
2. Cover Measures: Temporary and permanent cover measures shall be provided when necessary to
protect disturbed areas. The intent of these measures is to prevent erosion by having as much area as
possible covered during any period of precipitation.
3. Perimeter Protection: Perimeter protection to filter sediment from sheet flow shall be provided
downstream of all disturbed areas prior to upslope grading.
4. Traffic Area Stabilization: Unsurfaced entrances, roads, and parking areas used by construction traffic
shall be stabilized to minimize erosion and tracking of sediment off-site.
Renton Market – City of Renton

5. Sediment Retention: Surface water collected from all disturbed areas of the site shall be routed
through a sediment pond or trap prior to release from the site, except those areas at the perimeter of the
site small enough to be treated solely with perimeter protection. Sediment retention facilities shall be
installed prior to grading any contributing area.
6. Surface Water Collection: Surface water collection measures (e.g., ditches, berms, etc.) shall be
installed to intercept all surface water from disturbed areas, convey it to a sediment pond or trap, and
discharge it downstream of any disturbed areas. Areas at the perimeter of the site, which are small
enough to be treated solely with perimeter protection, do not require surface water collection. Significant
sources of upstream surface water that drain onto disturbed areas shall be intercepted and conveyed to
a stabilized discharge point downstream of the disturbed areas. Surface water collection measures shall
be installed concurrently with or immediately following rough grading and shall be designed,
constructed, and stabilized as needed to minimize erosion.
7. Dewatering Control: The water resulting from construction site dewatering activities must be treated
prior to discharge or disposed of as specified.
8. Dust Control: Preventative measures to minimize wind transport of soil shall be implemented when a
traffic hazard may be created or when sediment transported by wind is likely to be deposited in water
resources.
9. Flow Control: Surface water from disturbed areas must be routed through the project’s on-site flow
control facility or other provisions must be made to prevent increases in the existing site conditions
2-year and 10-year runoff peaks discharging from the project site during construction (flow control
facility, runoff treatment facility, and on-site BMP areas [existing or proposed] shall not be used for this
purpose).
10. Control Pollutants: Stormwater pollution prevention (SWPPS) measures are required to prevent,
reduce, or eliminate the discharge of pollutants to on-site or adjacent stormwater systems or
watercourses from construction-related activities such as materials delivery and storage, on-site
equipment fueling and maintenance, demolition of existing buildings and disposition of demolition
materials and other waste, and concrete handling, washout and disposal. Section D.2.2 describes BMPs
specific to this purpose; additionally, several of the ESC BMPs described herein are applicable.
11. Protect Existing and Proposed Stormwater Facilities and On-Site BMPs: Sedimentation and soil
compaction reduce the infiltration capacity of native and engineered soils. Protection measures shall be
applied/installed and maintained so as to prevent adverse impacts to existing stormwater facilities and
on-site BMPs and areas of proposed stormwater facilities and on-site BMPs for the project. Adverse
impacts can prompt the requirement to restore or replace affected stormwater facilities and on-site
BMPs.
12. Maintain Protective BMPs: Protection measures shall be maintained to ensure continued performance
of their intended function, to prevent adverse impacts to existing BMPs/facilities and areas of proposed
BMPs/facilities, and protect other disturbed areas of the project.
13. Manage the Project: Coordination and timing of site development activities relative to ESC concerns,
and timely inspection, maintenance and update of protective measures are necessary to effectively
manage the project and ensure the success of protective ESC and SWPPS design and implementation.
PART 8.B: STORMWATER POLLUTION PREVENTION AND SPILL CONTROL
PLAN DESIGN
Stormwater pollution prevention and spill control (SWPPS) measures will be implemented per Section D.2.2 of
the RSWDM.
• Follow effective pollutant handling and disposal procedures.

NOTES TO USERS
This map is for use in administering the National Flood Insurance Program. It doesnot necessarily identify all areas subject to flooding, particularly from local drainagesources of small size. The community map repository should be consulted forpossible updated or additional flood hazard information.
To obtain more detailed information in areas where Base Flood Elevations (BFEs)and/or floodways have been determined, users are encouraged to consult the FloodProfiles and Floodway Data and/or Summary of Stillwater Elevations tables containedwithin the Flood Insurance Study (FIS) Report that accompanies this FIRM. Usersshould be aware that BFEs shown on the FIRM represent rounded whole-footelevations. These BFEs are intended for flood insurance rating purposes only andshould not be used as the sole source of flood elevation information. Accordingly,flood elevation data presented in the FIS Report should be utilized in conjunction withthe FIRM for purposes of construction and/or floodplain management.
Coastal Base Flood Elevations shown on this map apply only landward of 0.0’North American Vertical Datum of 1988 (NAVD 88). Users of this FIRM should beaware that coastal flood elevations are also provided in the Summary of StillwaterElevations table in the Flood Insurance Study Report for this jurisdiction. Elevationsshown in the Summary of Stillwater Elevations table should be used for constructionand/or floodplain management purposes when they are higher than the elevationsshown on this FIRM.
Boundaries of the floodways were computed at cross sections and interpolatedbetween cross sections. The floodways were based on hydraulic considerations withregard to requirements of the National Flood Insurance Program. Floodway widthsand other pertinent floodway data are provided in the Flood Insurance Study Reportfor this jurisdiction.
Certain areas not in Special Flood Hazard Areas may be protected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy Report for information on flood control structures for this jurisdiction.
Provisionally Accredited Levee Notes to Users: Check with your localcommunity to obtain more information, such as the estimated level of protectionprovided (which may exceed the 1-percent-annual-chance level) and EmergencyAction Plan, on the levee system(s) shown as providing protection for areas onthis panel. To maintain accreditation, the levee owner or community is requiredto submit the data and documentation necessary to comply with Section 65.10 ofthe NFIP regulations by November 01, 2018. If the community or owner doesnot provide the necessary data and documentation or if the data anddocumentation provided indicate the levee system does not comply withSection 65.10 requirements, FEMA will revise the flood hazard and riskinformation for this area to reflect de-accreditation of the levee system. Tomitigate flood risk in residual risk areas, property owners and residents areencouraged to consider flood insurance and floodproofing or other protectivemeasures. For more information on flood insurance, interested parties shouldvisit the FEMA Website at http://www.fema.gov/national-flood-insurance-program.
The projection used in the preparation of this map was Universal TransverseMercator (UTM) zone 10. The horizontal datum was NAD 83, GRS 1980spheroid. Differences in datum, spheroid, projection or UTM zones used in theproduction of FIRMs for adjacent jurisdictions may result in slight positionaldifferences in map features across jurisdiction boundaries. These differences do notaffect the accuracy of this FIRM.
Flood elevations on this map are referenced to the North American Vertical Datum of1988. These flood elevations must be compared to structure and ground elevationsreferenced to the same vertical datum. For information regarding conversionbetween the National Geodetic Vertical Datum of 1929 and the North AmericanVertical Datum of 1988, visit the National Geodetic Survey website athttp://www.ngs.noaa.gov or contact the National Geodetic Survey at the followingaddress:
NGS Information ServicesNOAA, N/NGS12National Geodetic SurveySSMC-3, #92021315 East-West HighwaySilver Spring, Maryland 20910-3282(301) 713-3242
To obtain current elevation, description, and/or location information for bench marksshown on this map, please contact the Information Services Branch of the NationalGeodetic Survey at (301) 713- 3242, or visit its website at http://www.ngs.noaa.gov.
Base Map information shown on the FIRM was derived from multiplesources. Base map files were provided in digital format by King County GIS, WADNR, WSDOT, and Pierce County GIS. This information was compiled at scales of1:12,000 to 24,000 during the time period of 1994-2012.
The profile baselines depicted on this map represent the hydraulic modeling baselines that match the flood profiles in the FIS report. As a result of improved topographic data, the profile baseline, in some cases, may deviate significantly from the channel centerline or appear outside the SFHA.
Based on updated topographic information, this map reflects more detailed andup-to-date stream channel configurations and floodplain delineations thanthose shown on the previous FIRM for this jurisdiction. As a result, the FloodProfiles and Floodway Data tables for multiple streams in the FloodInsurance Study Report (which contains authoritative hydraulic data) may reflectstream channel distances that differ from what is shown on the map. Also, the road to floodplain relationships for unrevised streams may differ from what isshown on previous maps.
Corporate limits shown on this map are based on the best data available at the timeof publication. Because changes due to annexations or de-annexations may haveoccurred after this map was published, map users should contact appropriatecommunity officials to verify current corporate limit locations.
Please refer to the separately printed Map Index for an overview map of thecounty showing the layout of map panels; community map repository addresses;and a Listing of Communities table containing National Flood Insurance Programdates for each community as well as a listing of the panels on which each communityis located.
For information on available products associated with this FIRM visit the MapService Center (MSC) website at http://msc.fema.gov. Available products mayinclude previously issued Letters of Map Change, a Flood Insurance Study Report,and/or digital versions of this map. Many of these products can be ordered orobtained directly from the MSC website.
If you have questions about this map, how to order products, or the NationalFlood Insurance Program in general, please call the FEMA Map InformationeXchange (FMIX) at 1-877-FEMA-MAP (1-877-336-2627) or visit the FEMAwebsite at http://www.fema.gov/business/nfip.
