July 11. 2016 Signed/Date TCE Renton Restaurant Addition Page 5 of 11 Section 1 – Project Overview The project consists of remodel of and addition to an existing restaurant located at 17930 108th Avenue SE. The existing KC parcel (#252604-9019) is approximately 37,874 square feet (0.85 acres) in size and contains an existing restaurant building with about 5,000 square feet roof, along with walkways, asphalt pavement and parking. Please refer to Figure 4, Existing Conditions. The site is considered flat with average gentle slopes (about 3%). The parcel is zoned C, and is located in the NE Quarter of Section 31, Township 23 N, Range 5 E, W.M. King County, Washington. The project site is shown in the vicinity map. The addition around the existing restaurant will make the roof area about 8,348 square feet. The outer edges of the asphalt pavement will be expanded with the use of permeable asphalt. Most of the existing asphalt pavement will remain as is. Walkways around the restaurants will be constructed over the existing base course of the existing pavements, without disturbing the subgrade, so as not to be counted as new impervious surface. An existing drainage system consisting of catch basins and drains will be modified to allow runoff sheet flow to new bio-retention cell. An existing detention tank also will continue to service the development with a modified control Tee. The additional pavement being permeable asphalt will be credited as 50% pervious. A new bio-retention cell is proposed at the north east portion of the property to service north half of the roof and the area of parking east of the building. Existing trees along the east property line will be preserved and a couple of interior ornamental trees will be relocated on site. Existing trees along the west property line have to be removed to make space for the bio-retention cell there. The Existing soils on the site are mapped by the NRCS as being type AgB – Alderwood Gravelly Sandy Loam. Please refer to Figure 3, NRCS Soils Map below. The Hydrologic Group of AgB is B TCE Renton Restaurant Addition Page 6 of 11 Section 2 – Conditions and Requirements Summary The following summary describes how this project will meet the eight “Core Requirements” and the “Special Requirements” that apply: Core Requirements 1. Discharge at the natural location: This site currently sheet flows to the west and collects in existing catch basins. From these catch basins the surface water is conveyed by 8” drains to an existing detention tank located along the west property line. The discharge from the detention tank is to the City drainage system located within 108th Avenue SE right of way. The proposed drainage system for this project will continue to collect the surface water runoff at the same detention pipe via the new bio-retention, and then continue to discharge to the same existing City drainage system located within 108th Avenue SE right of way. No change in the existing discharge location is proposed. 2. Off-site Analysis: A Level 1 off-site analysis was completed for this project and is included in Section 3 of this Technical Information Report. No significant downstream drainage problems were found. 3. Flow control: The proposed method of flow control is to continue to utilize the same existing detention tank in combination with a new bio-retention cell. The extension of the paving will be provided by permeable asphalt, thereby infiltrating the runoff from the expanded parking area. Please refer to Figure 6, Contributing Basin Map and Section 4 of this report. 4. Conveyance system: Flows will be conveyed by means of overland sheet flow runoff to the treatment areas and roof drains from the north portion of the roof. 5. Erosion and sedimentation control: A Temporary Erosion and Sedimentation Control plan, notes and details are included in this engineering submittal. 6. Maintenance and Operations: The existing storm drainage collection system on the property will continue to be privately owned and maintained. The new bio-retention will be privately owned and maintained. With the right of way dedication, the existing detention system comes to be located in the right of way, and therefore, the detention facility will be owned and operated by the City. Please refer to Section 10 of this report. 7. Financial guarantees and liability: The owner/contractor will be required to post construction performance and one year maintenance bonds for the redevelopment work associated with this project. A bond quantities spreadsheet for the proposed development will be prepared as required upon initial City review of the engineering plans. TCE Renton Restaurant Addition Page 7 of 11 8. Water Quality: almost 100% of the runoff is being received and infiltrated by the proposed bio-retention cells prior to discharge, if any. The new impervious/replaced surface subject to vehicular traffic does not meet the threshold of greater than 5,000 square feet for this project. As a result, the project is not required to provide water quality treatment. Special Requirements 1. Other adopted area-specific requirements: Enhanced Flow Control 2. Floodplain/Floodway delineation: Not applicable. 3. Flood protection facilities: Not applicable. 4. Source controls: No storage of hazardous substances exposed to elements. 5. Oil Control: Not a high use site. TCE Renton Restaurant Addition Page 8 of 11 Section 3 – Off-site Analysis This Level 1 Downstream Analysis is submitted as required by Core Requirement #2, Section 1.2.2, of the 2009 KCSWDM. Core Requirement #2 requires a qualitative analysis of upstream and downstream drainage conditions with an initial project submittal. Task 1: Study Area Definition and Maps: See Section-1 Project Overview of this report for a detailed Study Area Definition. Task 2: Resource Review: Resources reviewed include the site survey, iMap, and King County Road Services map vault. It appears that the downstream system is a part of the 24” bypass system through the shopping center across the street from the project site. The pipe downstream is 24” CMP discharging to a 30” CMP on the southside of Carr Road. The quarter mile point appears to be at the intersection of 105th Place SE and SE Carr Road. A sensitive areas review shows no critical areas on or near the project site. There were numerous official drainage complaint records on file with King County that are surrounding this property. It appears most of these are very old complaints and have been closed for quite a while. They relate to annexation of the area and new municipal code requirements regarding water quality issues noticed during jurisdiction staff. The complaint in the subject property was closed on 9/29/04. Task 3: Field Inspection: A field observation of the site and downstream analysis were performed on March 18, 2016 and again on July 8. The weather was overcast during the first visit and clear on the second. None of the downstream system beyond the second catch basin downstream shown on the survey is visible. The pipe diameters, however, seem adequate to convey the discharge anticipated even at a 100 year storm event from the site. Task 4: Drainage System Description and Problem Descriptions: Upstream: There are no upstream drainage conditions, because the drainage system within 109th Avenue SE has its drainage system that cuts the drainage away from the site. The slope on the properties to the north and south is parallel to the project site and they do not transfer any runoff on to this project site. Downstream: The downstream drainage system is the 24”concrete City drainage system in 108th Avenue SE flowing south for a distance of about 160 feet. Another 24” concrete pipe to the west conveys the drainage to the above mentioned 24” bypass system. All pipes in the bypass system are 24” CMP pipes. The final leg of the downstream system to the quarter mile point in 105th Place SE is 36” CMP. At quarter mile point the downstream connects ti a 30” CMP. The downstream drainage system is substantial in size and at reasonable slopes. Please see the figure depicting the downstream system. Task 5 – Mitigation of Existing or Potential Problems: TCE Renton Restaurant Addition Page 9 of 11 Existing capacity in the downstream system has been evaluated to be adequate to provide conveyance for the discharge from this project. TCE Renton Restaurant Addition Page 10 of 11 Section 4 – Proposed Site Conditions and Design Parameters Flow Control Analysis and Design In the existing conditions the flow control for this project is provided by an existing detention tank located along the west property line. The same detention tank will continue to be used for proposed conditions in combination with a new bio-retention cell. Please see sheet C-3.1 of the civil drawings. The profile and sections depict the existing detention system and proposed addition of the bio-retention cell along the west property line. The surveyed elevation of the overflow riser confirms our belief that the detention tank is a 52 feet long 48” diameter corrugated metal pipe laid at a slope. The manholes were locked and no drawings are available with the owner to separately confirm this. The control structure is 54” in diameter and the other being a 48” diameter structure. Please see the drainage basin maps included in this report for the proposed drainage basins. The site is being divided into two separate drainage basins. The southwest basin consists of the south half of the proposed roof and the south/west improvements, including the permeable pavement being added. The northeast basin consists of the north half of the proposed roof and the north/east improvements, such as permeable parking and pervious areas. In the WWHM2012 analysis these are indicated as Basin 1 and 2 respectively. We have claimed 50% pervious credit for the permeable pavement being added. Two bio-retention cells are being added, one in each drainage basin. The northeast bio-retention cell is designed to be completely infiltrated. An overflow route is provided to the west parking via a curb cut. The southwest basin drains to the bio-retention cell with sheet flow of runoff over pavements into the bio-retention. Over 99% of the drainage is infiltrated. The overflow from the bio-retention is into a catch basin with a beehive grate. This overflow is received into the detention tank and controlled discharge is released into the City storm sewer system within 108th Avenue NE. Please see the Areas Summary on C-0 of the drawings and the one included within this report in the Appendix. Water Quality Analysis and Design The analysis report from the WWHM2012 program shows that 100% of the runoff generated from the northeast basin is infiltrated at the bio-retention proposed at the northeast portion of the basin. Over 99% of the runoff generated from the southwest basin is infiltrated at the bio-retention proposed along the west property line. The total new/replaced impervious surface does not meet or exceed the threshold for water quality area. TCE Renton Restaurant Addition Page 11 of 11 Section 5 – Conveyance System Analysis and Design The existing conveyance system on site is being modified to allow sheetflow of the runoff over pavement into the bio-retention cells. The most flow would occur where the overflow from the southwest bio-retention is conveyed into the detention pipe. The peak rate of flow expected at the 100 year 24 hour is 0.033 cfs. The capacity of the 8” corrugated metal pipe at 5.3% can be calculated to be 1.49 cfs. The capacity of the 12” concrete discharge pipe from the control structure at 2.8% is 3.24 cfs. Therefore in our opinion the existing conveyance system is adequate to service the proposed development too. Section 6 – Special Reports and Studies We are not aware of any Special Reports or Studies associated with the property proposed to be redeveloped or in the near vicinity. Section 7 – Other Permits City of Renton Building Permit Soos Creek Water & Sewer District water, sewer, fire, and irrigation services approval. Section 8 – ESC Analysis and Design Standard erosion and sedimentation control BMPs are proposed. Drawing sheet C-1 is dedicated to show clearing limits, construction entrance, dust control, inlet protection, matting & mulching, silt fence, and tree protection. Prior to beginning any work these BMPs will be installed and operational. Upon completion of earthwork and stabilization of worked areas, these NMPs will be removed. Section 9 – Financial Guarantees The project proposes to add new dining area around the shell of the existing building. Permeable asphalt is proposed to facilitate expansion of paved areas on site. The work in the right of way consists of replacing the existing driveway entrance with a driveway entrance to current standards. Our understanding is that at this time the right of way will be dedicated. The work in the right of way will be limited to that associated with the installation of the new driveway entrance, such as sidewalk reconnection and curb tapering to the driveway entrance. The bond quantities consisting of pavements, detention tank, and bio-retention cells is submitted for your review. Section 10 – Operations and Maintenance Manual The operation and maintenance manual consisting of detention tank and bio-retention is being submitted.

Soils areassigned to one of four groups according to the rate of water infiltration when thesoils are not protected by vegetation, are thoroughly wet, and receive precipitationfrom long-duration storms.The soils in the United States are assigned to four groups (A, B, C, and D) andthree dual classes (A/D, B/D, and C/D). The groups are defined as follows:Group A. Soils having a high infiltration rate (low runoff potential) when thoroughlywet. These consist mainly of deep, well drained to excessively drained sands orgravelly sands. These soils have a high rate of water transmission.Group B. Soils having a moderate infiltration rate when thoroughly wet. Theseconsist chiefly of moderately deep or deep, moderately well drained or well drainedsoils that have moderately fine texture to moderately coarse texture. These soilshave a moderate rate of water transmission.Group C. Soils having a slow infiltration rate when thoroughly wet. These consistchiefly of soils having a layer that impedes the downward movement of water orsoils of moderately fine texture or fine texture. These soils have a slow rate of watertransmission.Group D. Soils having a very slow infiltration rate (high runoff potential) whenthoroughly wet. These consist chiefly of clays that have a high shrink-swellpotential, soils that have a high water table, soils that have a claypan or clay layerat or near the surface, and soils that are shallow over nearly impervious material.These soils have a very slow rate of water transmission.If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter isfor drained areas and the second is for undrained areas. Only the soils that in theirnatural condition are in group D are assigned to dual classes.Hydrologic Soil Group—King County Area, WashingtonTenton Restaurant AdditionNatural ResourcesConservation ServiceWeb Soil SurveyNational Cooperative Soil Survey3/22/2016Page 3 of 4 Rating OptionsAggregation Method: Dominant ConditionComponent Percent Cutoff: None SpecifiedTie-break Rule: HigherHydrologic Soil Group—King County Area, WashingtonTenton Restaurant AdditionNatural ResourcesConservation ServiceWeb Soil SurveyNational Cooperative Soil Survey3/22/2016Page 4 of 4 EXISTING CONDITIONS MAP 1,636.8 ft 139.2 ft 185.8 ft185.8 ft 306.4 ft306.4 ft 120.4 ft120.4 ft 182.5 ft182.5 ft145.1 ft145.1 ft 145.1 ft145.1 ft 0.7 ft King County, Pictometry International Corp., King County King County iMap-Downstream Drainage Route Date: 7/11/2016 ±The information included on this map has been compiled by King County staff from a variety of sources and is subject to changewithout notice.
