Thanks, Ross Fenton NWR Design Build & 1405/SR167 Project Office 425-456-8538 / MS NB82-250 fentonr@consultant.wsdot.wa.gov From: Michael A Benoit [mailto:Mbenoit(d�Rentonwa.gov] Sent: Thursday, July 09, 2015 3:21 PM To: FentonRCcbconsultant.wsdot.wa.gov Subject: Talbot HII Sanitary Sewer Relocation Ross, As related to the sewer relocation, I am doing a check to make sure that our proposed design does not cut off sewer service to any of the homes that are remaining. Do you have an easy list of what properties have plans to be removed that could be sent to me. As an alternate, what would the proposal be, if any, for the following properties: 201 S 14th St — to remain 226 S 15th St — to remain 205 S 14th St — demolition ordered 1405 Davis Ave S — to remain 1402 Davis Ave S — to remain 1403 Shattuck Ave S — demolition ordered 1404 Shattuck Ave S — demolition complete 1406 Shattuck Ave S — to remain 1314 Whitworth Ave S — to remain What I am looking at is a house like 1404 Shattuck Ave S. Because the road slopes to the north, the typical side sewer connects to the main north of the house. When we set a new manhole to intercept the main in Shattuck to take it to the new deep line, we need to make sure the manhole is downstream from 1404's connection or have a provision to find and relocate their side sewer. We are lacking information on some side sewers (like 1404 Shattuck). I am going to have some investigation done to locate them and we would like to not expend the resources if the properties are on the list to go away. If you have any questions or need to talk about this, please let me know.

The submitted documents are acceptable for advertisement. In our review of the 100% documents we have found a few items that should be cleaned up prior to finalizing contract documents and award. These could be addressed through the addendum process. These include the following: 1. Plan Sheet 2 of 11, under Survey Notes: "201" should read "2013". 2. Plan Sheet 2 of 11, under Survey Notes minor editorial comments: a. On first sentence, "been" should be inserted after "has".

We will address the changes as a combination of addendum and minor changes during construction. 1. Plan Sheet 2 of 11, under Survey Notes: "201" should read "2013". Minor typo, will update only if sheet 2 is republished for addendum 2. Plan Sheet 2 of 11, under Survey Notes minor editorial comments: a. On first sentence, "been" should be inserted after "has". Minor typo, will update only if sheet 2 is republished for addendum b. On second sentence, "1-405," should be inserted after "the". Minor typo, will update only if sheet 2 is republished for addendum c. On first sentence of last paragraph, there's a typo for terrain. Minor typo, will update only if sheet 2 is republished for addendum 3. Plan Sheet 3 of 11: Configuration of S. 141h between Baseline S. 14th Sta. 14+00 and 18+50 has not been updated (see sheet 6 of 11 for updated configuration). Primary subject is construction base line — actual construction based upon sheets 5-9 - Won't change bidding 4. Plan Sheet 5 of 11: delete the Temporary Gravel Road on S. 141h Street between begin and 10+24 (+/-) so traffic on existing S. 141h Street is maintained. Will revise during construction (reduce gravel road pay item / increase asphalt patch 5. Plan Sheet 5 of 11: At Davis Avenue South delete the Temporary Gravel Access Road across Davis Avenue South (Private) and add a note that Private/ Public Ingress & Egress on Davis needs to be maintained. Lakeview Short Plat (6 remaining parcels on Davis between 1-405 and S. 15th ) contains a private access easement that connects S. 15`h to north with Shattuck Ave to north/east. The access for these parcels need to be maintained to the north until the relocated S. 141h Street is complete and open for public use. Will revise during construction (reduce gravel road pay item / increase asphalt patch 6. Plan Sheets 5-8 of 11: add width of temporary gravel road dimension to plan: 12' between 10+24 and 14+00, 18' between 14+00 and 23+00 (Morris), and 12' between 23+00 and 25+50 (Smithers). Not subject to addendum. Gravel road dimensions are scalable — if a drawing is revised for addendum, the note will be added. Information will be provided for construction 7. Plan Sheets 7 and 8 of 11: Extend Temporary Gravel Access Road to Smithers Avenue South. Modify the fill elevation accordingly (see attached redline). Will provide addendum to show extension of fill 1 a BASELINE I'S 14TH SP PTA!

The purpose our investigation was to utilize both provided and newly collected subsurface soil and groundwater data to provide earthwork recommendations and relevant soil, rock, and groundwater information for use in the design and construction of shallow and deep sewer utility infrastructure. The scope of work for the study consisted of the following: • A review of provided boring logs (WSDOT), groundwater elevation data, and soil and rock laboratory analyses; • Drilling and sampling three supplemental borings and conducting laboratory analyses on soil and rock samples; • Preparing cross sections, groundwater gradient maps, and organizing the subsurface data, and; • Preparing a geotechnical report describing the anticipated subsurface conditions, potential issues, and recommendations for aspects of earthwork construction. 2.0 Project Description The proposed project includes new gravity sewer lines placed by horizontal directional drilling (HDD), auger boring or pipe ramming, and open trenching methods from near the intersection of S. 141h Street and S. 15fh Street east toward Smithers Avenue S. and then to the north across I- 405, terminating in S. Renton Village Place. The Vicinity Map in Figure 1 shows the site location relative to nearby landmarks. The Site Plan in Figure 2 shows the location of the proposed alignment and manholes. It is our understanding that the new utility infrastructure will include 9 new sanitary sewer manholes (SSMH), approximately 1,600 lineal feet of 10-inch diameter polyvinylchloride (PVC) sewer pipe, approximately 1,200 lineal feet of 12-inch diameter horizontal directional drilling (HDD) placed pipe, and approximately 280 linear feet of pipe placed by auger boring or pipe ramming. The new pipe systems will be connected to existing utility infrastructure in the area. Open trenching will be utilized for much of the manhole and pipe placement that is less than 15 feet in depth. Des!gn with cummurity in mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 The HDD construction will extend west to east along the proposed new S. 14th Street alignment at depths ranging from 25 to 50 feet below grade. The HDD work is estimated to take 45 days to complete. The auger boring or pipe ramming will extend south to north below 1-405 and is estimated to take 25 to 30 days to complete. 3.0 Site Description A majority of the site is located south of 1-405 and between State Route (SR) 167 and Smithers Avenue South in Renton, Washington (Figure 1). The site also includes a north to south alignment along Smithers Avenue South extending north beneath 1-405, terminating at a new manhole in South Renton Village Place. The site area south of 1-405 is currently developed with single and multi -family residential structures, asphalt paved roadways, and landscaped areas. The site area north of 1-405 is primarily developed with asphalt paved parking lots/drive areas along with local commercial buildings. The site area generally slopes downward toward the north and northwest at low to moderate magnitudes. The area north of 1-405 is generally level. A concrete retaining wall and sound wall extends along the south side of 1-405 along the site area and a relatively shallow ditch extends along the north side of 1-405. There are local steep slopes in the western portion of the site; however, they are located north of the proposed utility alignments. 4.0 Subsurface Data 4.1.1 Site Investigation Program We have reviewed approximately 27 boring logs prepared by WSDOT following geotechnical soil drilling and rock coring for future roadway development in the area. The drilling occurred during multiple phases of geotechnical investigation work in the area between December 2013 and March 2014. From our review of the provided boring logs and boring log field notes/drafts, the borings were drilled using mud rotary methods through upper Quaternary sediments and rock coring with drill fluids into the underlying Tertiary bedrock. Soil and rock laboratory testing included sieve analyses, Atterberg limit tests, moisture determination, shear strength, consolidation, Slake durability tests, and unconfined compression strength testing (rock). Vibrating wire and 2 Design with community In mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 standpipe piezometers were installed in a majority of the borings and groundwater elevation data was obtained generally from January 2014 to October 2014. In June 2015, Stantec drilled three additional borings at or near locations requested by Staheli Trenchless Consultants to obtain additional information about the soil, rock, and groundwater conditions for use in their trenchless design. These borings were drilled using a CME-75 truck rig using hollow stem auger and mud rotary techniques. WSDOT drilled an additional boring near the DC-77 location along the north side of 1-405 in support of this work. Standpipe piezometers were installed in all four borings. The soils encountered were logged in the field during the exploration and are described in accordance with the Unified Soil Classification System (USCS). Disturbed soil samples were obtained by using a 140 pound hammer free falling a vertical distance of 30 inches for the borings. The summation of hammer -blows required to drive the sampler the final 12-inches of an 18-inch sample length is defined as the Standard Penetration Resistance, or N-value for a 140 pound hammer and 2 inch outside diameter split spoon sampler. Where bedrock was encountered, samples were collected continuously and described in general accordance with the Unified Rock Classification System (URCS). A Stantec field representative directed the drilling program, collected disturbed soil samples from split spoon sampler tubes, obtained rock core samples, classified the encountered soil and rock, kept a detailed log of each borehole, and observed and recorded pertinent site features. Stantec and WSDOT boring logs are enclosed in Appendix C. The results of provided (WSDOT) and recently conducted (Stantec) laboratory testing are provided in Appendix D. 5.0 Soil and Groundwater Conditions 5.1.1 Area Geology The site lies within the Puget Lowland. The lowland is part of a regional north -south trending trough that extends from southwestern British Columbia to near Eugene, Oregon. North of Olympia, Washington, this lowland is glacially carved, with a depositional and erosional history including at least four separate glacial advances/retreats. The Puget Lowland is bounded to the west by the Olympic Mountains and to the east by the Cascade Range. The lowland is filled with glacial and non -glacial sediments consisting of interbedded gravel, sand, silt, till, and peat lenses. The Geologic Map of King County, indicates that the site is located near the contacts between Alluvium, Modified Land, Vashon Recessional Outwash, and Tertiary Bedrock. 3 Design with community in mind (3 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 Alluvium in the Puget Lowland generally consists of varying mixtures of silt, sand, clay, gravel, and organic debris deposited in fluvial environments within the last several thousand years. Alluvium deposited by the Green River is variable in composition and density, and typically consists of soft/loose to stiff/medium dense stratified sand and silt with variable amounts of clay and peat. Alluvium in the Renton area can be over 100 feet in thickness. Modified Land deposits include artificial fill, either undocumented or controlled fill, placed within the last 100 years. These deposits are typically less than 20 feet in thickness in this area, and usually consist of variable density combinations of silt, gravel, and sand. Vashon Recessional Outwash consists of sand and gravel with local areas of silt and clay deposited during the most recent glacial recession. These materials are normally consolidated and are generally medium dense. Groundwater is commonly found perched within the outwash or at the base of the outwash where glacial till, Pre -Fraser deposits or bedrock is typically located. Tertiary Bedrock in this area consists of the Renton Formation. The Renton Formation includes feldspathic fine to medium grained sandstone with beds of coal, carbonaceous siltstone, and claystone. Tertiary Bedrock locally outcrops south of 1-90 and the Seattle Fault Zone due to uplift associated with seismic activity. 5.1.2 Subsurface Soil and Rock Conditions We have summarized the subsurface soil and bedrock conditions in the general area of the sewer alignment below. The cross sections (Figure 3) show the locations of the borings and provide a graphic interpretation of the subsurface soil and bedrock conditions. Boring logs can be found in Appendix C. Soil and rock laboratory analysis are summarized in the table below. Much of this information is graphically shown in Figure 4. Detailed results can be found in Appendix D. South 14th Street to Whitworth Avenue South From the west end of the alignment near South 14th Street upslope to the east side of the top of a ridge, the subsurface soils consist of loose to medium dense silty -sand and poorly graded sands with silt and variable amounts of gravel extending 10 to 15 feet below existing elevations. These materials are consistent with artificial fills, Vashon Recessional Outwash, and highly weathered sandstone. Weathered to slightly weathered sandstone with interbeds of siltstone and coal underlies these materials to the depths drilled. From the east side of the ridge extending east-northeast to Whitworth Avenue South, the subsurface soils include materials similar to those described above; however, the depth of the upper sediments increases to approximately 15 to 25 feet below existing elevations. Highly weathered to slightly weathered sandstone with interbeds of siltstone and coal underlies these materials to the depths drilled. 4 Design with community in mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 We anticipate that weathered bedrock will be encountered within the HDD alignment from S. 14th Street to the vicinity of Whitworth Avenue South. We anticipate that the transition from bedrock to soil will be encountered in the vicinity of Whitworth Avenue South. Near surface open trenching methods will encounter soil materials only. Whitworth Avenue South to Smithers Avenue South From the area near Whitworth Avenue South extending east-northeast to Smithers Avenue South, the subsurface soils consist of loose/soft to medium dense/stiff silty -sand and poorly graded sands with silt and gravel along with areas and/or interbeds of silt and sandy silt extending 20 to 40 feet below existing elevations. Localized organic soils (peat and/or organic debris) appear to be present in the upper elevations of the ravine area near DC-60. These materials are consistent with artificial fills, wetland deposits, Vashon Recessional Outwash, and at depth, highly weathered sandstone. Weathered to slightly weathered sandstone with interbeds of siltstone and coal underlies these materials to the depths drilled. We anticipate that highly variable density silty -sands will be encountered in a majority of the sewer alignment in this area. Moderate to heavy groundwater should be anticipated east of Whitworth Avenue South. Smithers Avenue South to South Renton Village Place The Smithers Avenue South to South Renton Village Place alignment is underlain by loose to medium dense mixtures of sand, silty -sand, and sandy silt, consistent with artificial fill and Vashon Recessional Outwash deposits. These materials extend to at least 20 feet below existing grades. The borings generally indicate that loose to medium dense poorly graded sands grade to silty - sands from south to north along this alignment. Variable amounts of gravel and interbeds of silt should be anticipated and groundwater is present at or below 40 feet in elevation. Renton Formation - Site Specific Description The Renton Formation includes feldspathic sandstone, siltstone, coal seams, minor claystone, along with areas of sandstone with siltstone clasts and minor coal lenses and/or laminae. A large majority of the sandstone encountered in the borings is described as "very weak rock". Unconfined compression testing of core samples confirms this overall designation. These tests yield strength of approximately 27 to 150 pounds per square inch (psi). Somewhat stronger rock, with unconfined compression strengths of approximately 700 to 1,900 psi is present at an elevation of approximately 50 feet below Davis Avenue South extending toward the east. In general, discontinuities within the sandstone are in fair to good condition and the Rock Quality Designation (RQD) is primarily greater than 80 percent. It should be noted that sandstone was washed out by drilling fluids (polymer and bentonite based) in several borings (shown in Figure 5 Design with community in mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 5). Some of these are noted at or near the HDD alignment from near DC-47 east to Whitworth Avenue South. Slake durability tests confirm that the sandstone erodes readily under fluid flows. Upper Soil Materials - Site Specific Description The upper soils include undocumented fill, Vashon Recessional Outwash, and highly weathered Renton Formation. A majority of the soils consist of silty -sand with variable amounts of gravel. Areas of poorly graded sand with gravel are present in borings near the east and west ends of the alignment, near S. 14th Street and Smithers Avenue South. Localized sandy silt, clayey silt, and silt are present throughout the site area at relatively shallow depths. In general, the soil materials are loose to medium dense. There are localized areas and layers of very soft silt, peat, and loose granular soils near the contact with Renton Formation and near the ground surface. 5.1.3 Soil and Rock Laboratory Analyses The following table provides a summary of the results of various laboratory analyses conducted on selected soil and rock samples.

This data can be found in Appendix D. Groundwater levels measured during drilling of MW-1 through MW-3 ranged from approximately 10 to 30 feet below existing grades. Groundwater appears to be located within Vashon Recessional Outwash deposits east of Shattuck Avenue South and within sandstone deposits (Renton Formation) west of Shattuck Avenue South. The data indicates that groundwater fluctuates between 3 and 12 feet between the high and low levels. Soil conditions suggest that local perched groundwater may be encountered above the groundwater levels described above. The groundwater flow directions appear to be an expression of the surface topography at the site. Groundwater appears to flow west-northwest and east-northeast from the top of the ridge near Davis Avenue South and generally toward the north along Smithers Avenue South. Groundwater contours and interpreted gradient directions can be found in Figure 6. Design with community in mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 The following table provides a summary of groundwater elevations in the vicinity of the sewer alignments.

The groundwater level will depend on a variety of factors that include seasonal precipitation, irrigation, land use, climatic conditions and soil permeability. Water levels at the time of the field investigations may be different from those encountered during the construction phases of the project. In general, groundwater is expected to be highest between December and May and at seasonal low elevations between August and October. 6.0 Geologic Hazards 6.1.1 Erosion Hazard The Natural Resources Conservation Services (NRCS) maps for King County indicate that the north half of the site, generally S. 141h Street to S. Renton Village Place, is underlain by Urban land soils. These soils are derived from artificial fill materials and typically have a "Slight" erosion potential in a disturbed state. The south and upland portion of the site is underlain by Beausite gravelly sandy loam (6 to 15 percent slopes). These soils have a "Slight" to "Moderate" erosion potential in a disturbed state. It is our opinion that soil erosion potential at this project site can be reduced through landscaping and surface water runoff control. Typically erosion of exposed soils will be most noticeable during periods of rainfall and may be controlled by the use of normal temporary erosion control measures, such as silt fences, hay bales, mulching, control ditches and diversion trenches. The typical wet weather season, with regard to site grading, is from October 31 st to April lst. Erosion control measures should be in place before the onset of wet weather and are required throughout the construction. 6.1.2 Seismic Hazard The subsurface soils at the site are generally medium dense to very dense below a variable thickness of fill. The overall subsurface profile corresponds to a Site Class D as defined by Table 1613.5.2 of the 2012 International Building Code (2012 IBC). A Site Class D applies to a profile consisting of medium dense/stiff to very dense/hard materials within the upper 100 feet. We referenced the U.S. Geological Survey (USGS) Earthquake Hazards Program Website to obtain values for Ss, S 1, Fa, and Fv. The USGS website includes the most updated published data on seismic conditions. The site specific seismic design parameters and adjusted maximum spectral response acceleration parameters are as follows: UK Design v„th r_omrnuri'y in —ind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 PGA (Peak Ground Acceleration, in percent of g) Ss 143.10% of g S1 53.40% of g Fa 1.00 Fv 1.50 Additional seismic considerations include liquefaction potential and amplification of ground motions by soft soil deposits. The liquefaction potential is highest for loose sand with a high groundwater table. The relatively dense soil materials that underlie the site have a low potential for liquefaction and/or amplification of ground motions. 7.0 Discussion 7.1.1 General South 14th Street Alignment - Shallow Infrastructure & Manholes We anticipate that loose to medium dense soils, primarily consisting of silty -sand with gravel, will be encountered in sewer line and manhole excavations in this area. Sandstone could be encountered in excavations for SSMH-9 and should be expected below an elevation of 80 feet in the area of SSMH-8. Groundwater may be encountered in the excavation of SSMH-8 and SSMH-9, and also between SSMH-5 and SSMH-4. Groundwater should be expected in excavations east of SSMH-4 (Morris Avenue South). Potential Issues Primary geotechnical issues that may affect construction include very loose/soft soil conditions below new utility lines and manholes and the need for de -watering east of SSMH-5 and potentially at SSMH-8 and SSMH-9. Rock blasting, coring, or breaking will be necessary during excavation for SSMH-8. Temporary shoring for manhole placement will be necessary at SSMH-9 and may be necessary at SSMH-8 depending on whether personnel will enter the excavation. Local shallow over -excavation and replacement may be required to create a suitable bearing substrate for new shallow infrastructure. This could include removal of 1 to 2 feet or more of any loose soil materials followed by replacement with two to four inch sized quarry rock. Site and location specific recommendations should be provided if loose soil conditions are encountered during construction. Design with community In rand 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 If excavation work occurs when groundwater is at or near seasonal low elevations (typically June through October), de -watering may not be necessary east of SSMH-4. If de -watering is required, we anticipate that local sump excavations or well points will be adequate to lower the groundwater to allow for utility placement in the area. South 14th Street Alignment - Deep Infrastructure The HDD construction will encounter very weak to moderately weak sandstone and siltstone, and potentially coal seams from the area of SSMH-8 to near SSMH-5. In the area of SSMH-5 (Whitworth Avenue South), the horizontal drilling will daylight through the Renton Formation and into recessional outwash deposits. Potential Issues Rock coring and laboratory analysis indicate that the sandstone will erode readily by fluid actions. Samples were washed out at or near proposed HDD depths between Davis Avenue South and Whitworth Avenue South. While testing indicates that the sandstone is predominately very weak, we observed locally competent materials ranging from a few centimeters to over 2 feet in thickness in MW-3. Additionally, interbeds of siltstone and clay are present near the HDD alignment at Shattuck Avenue South which will likely have varying strengths. While most contacts and discontinuities are described as horizontal, some dip 5 to 50 degrees in the area between DC-47 to DC-60 at depths ranging from 20 to 45 feet below existing grades. Variability in rock composition and strength should be expected. Smithers Avenue South Alignment We anticipate that loose to medium dense soils, primarily consisting of poorly graded sand, sandy silt, and silty -sand with gravel, will be encountered in sewer line, pits required for trenchless construction methods, and manhole excavations in this area. Groundwater may be encountered between SSMH-3 and SSMH-2. Groundwater should be expected in excavations east of SSMH-2. Significant groundwater should be anticipated in excavations north of 1-405 where groundwater elevations range from 32 to 36 feet and excavations extend to an elevation of approximately 21 feet. The auger boring or pipe ramming construction will likely occur below the groundwater table. We anticipate that the soil conditions will consist of medium dense silty -sands with variable amounts of gravel. F, Design with community In mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 Potential Issues Primary geotechnical issues that may affect construction include very loose/soft soil conditions below new utility lines and manholes and the need for de -watering and temporary shoring for manhole placement. Groundwater de -watering may be necessary between SSMH-3 and SSMH-2 depending on the season in which construction takes place. Significant groundwater de -watering, potentially include sheet pile shoring, should be anticipated in the trench north of the auger boring/pipe ramming extending to SSMH-1, where excavations will extend 10 to 15 feet below the regional groundwater table. In this area, the soils likely consist of loose to medium dense silty -sands and poorly graded sands. Temporary shoring for placement of SSMH-1 could include large square trench boxes, soldier piles with lagging, or for a more water tight option, interlocking steel sheet piles with bracing. We can provide additional recommendations upon request. Local shallow over -excavation and replacement may be required to create a suitable bearing substrate for new shallow infrastructure. This could include removal of 1 to 2 feet or more of any loose soil materials followed by replacement with two to four inch sized quarry rock. Site and location specific recommendations should be provided if loose soil conditions are encountered during construction. Nearly 10 feet of very soft organic soils (possibly peat) were encountered in DC-60, located northwest of SSMH-3. Based on the topography and vegetation in this area, organic laden soils may be present in excavations up to 150 feet west of SSMH-3. Organic soils are not suitable for use as structural fill or as trench backfill. 8.0 Recommendations 8.1.1 Site Preparation Based on observations from the site investigation program and the results of the exploration program, it is anticipated that the stripping depth will range from approximately 0 to 18 inches within the site areas. The excavated material is not suitable as fill material within areas with structural development, but could be used as fill material in non -settlement sensitive areas such as landscaping. In these non -settlement sensitive areas, the fill should be placed in maximum 12 inch thick lifts that should be compacted to at least 90 percent of the modified proctor maximum dry density (ASTM D 1557 Test Method). 13 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 During wet weather conditions, which typically occur from October through May, subgrade stability problems and grading difficulties may develop due to excess moisture, disturbance of sensitive soils and/or the presence of perched groundwater. Construction during the extended wet weather periods will likely create the need to over -excavate exposed soils as they become disturbed and cannot be re -compacted due to elevated moisture contents. A majority of the near -surface soils have relatively high silt contents that could result in moisture sensitivity for these materials. If earthwork occurs during the months of October through May, a majority of the excavated soils will likely not be suitable for use as structural fill. If the native soils are used as structural fill, we recommend that the soils are relatively free of organic material and debris, and that the materials are within ±2 percent of the optimum moisture content. Aeration and drying of the native soils may be necessary to achieve near optimum moisture conditions. Furthermore, the weathered glacial till will be over -optimum in moisture content and may not be able to be dried during a typical summer. If the native soils are stockpiled for later use as structural fill, the stockpiles should be covered to protect the soil from wet weather conditions. We recommend that a representative of Stantec be on site during the excavation work to determine which soils are suitable for structural fill. Imported structural fill material should consist of well -graded gravel or a sand and gravel mixture with a maximum grain size of 3 inches and less than 5 percent fines (material passing the U.S. Standard No. 200 Sieve). All structural fill material should be submitted for approval to the geotechnical engineer prior to delivery to the site. Structural fill should be placed in horizontal lifts not exceeding 12 inches loose thickness, moisture -conditioned as necessary, (moisture content of soil shall not vary by more than ±2 percent of optimum moisture) and the material should be compacted to at least 95 percent of the maximum dry density based on ASTM Test Method D1557. In place density tests should be performed on all structural fill to verify proper moisture content and adequate compaction. Additional lifts should not be placed if the previous lift did not meet the compaction requirements or if soil conditions are not considered stable. Observations of fill materials could indicate excessively wet, pumping soils which would warrant non -passing evaluation, even if the minimum compaction requirement is met. 8.1.2 Temporary Excavations Based on our understanding of the project, we anticipate that excavation work could include cuts of up to 30 feet below existing grades for utility and manhole placement. The average excavation depth for sewer line and manhole placement is expected to be about 10 feet. The deeper excavations include SSMH-1, SSMH-8, and SSMH-9. 14 Drs1gr) V. ih CCJrJJM,r it r in mind C�' GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 The following recommendations are applicable for temporary excavations if trench boxes will not be utilized and there is space for the excavation work. For excavations that extend more than 4 feet below grade, we recommend that they be sloped no steeper than 1.51-1:1 V (Horizontal:Vertical) in loose to medium dense soils, 1 H:1 V in medium dense to dense native soils, and 3/4H:1 V in very dense native soils (if encountered in deeper excavations). If trench box shoring is used, temporary excavations may be sloped to near vertical for short-term periods during placement (as feasible). Vertical excavations greater than 4 feet may not be possible in areas underlain by fill and recessional outwash deposits. If an excavation is subject to heavy vibration or surcharge loads, we recommend that the excavations be sloped no steeper than 2H:1 V in loose to medium dense soils and 1.51-1:1 V in all other soils, where room permits. All temporary cuts should be in accordance with the Washington Administrative Code (WAC) Part N, Excavation, Trenching, and Shoring. The temporary slopes should be visually inspected daily by a qualified person during construction activities and the inspections should be documented in daily reports. The contractor is responsible for maintaining the stability of the temporary cut slopes and reducing slope erosion during construction. The temporary cut slopes should be covered with visqueen to help reduce erosion during wet weather, and the slopes should be closely monitored until the permanent retaining systems or slope configurations are complete. Materials should not be stored or equipment operated within 10 feet of the top of any temporary cut slope. Soil conditions may not be completely known from the geotechnical investigation. In the case of temporary cuts, the existing soil conditions may not be completely revealed until the excavation work exposes the soil. Typically, as excavation work progresses the maximum inclination of the temporary slopes will need to be re-evaluated by the geotechnical engineer so that supplemental recommendations can be made. Soil and groundwater conditions can be highly variable. Scheduling for soil work will need to be adjustable to deal with unanticipated conditions so that the project can proceed and required deadlines can be met. If any variations or undesirable conditions are encountered during construction, Stantec should be notified so that supplemental recommendations can be made. If room constraints or groundwater conditions do not permit temporary slopes to be cut to the maximum angles allowed by the WAC, temporary shoring systems may be required. The contractor should be responsible for developing temporary shoring systems, if needed. We recommend that Stantec and the project structural engineer review temporary shoring designs prior to installation, to verify the suitability of the proposed systems. 15 Design with commxmtty In mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 8.1.3 Erosion and Sediment Control Erosion and sediment control (ESC) is used to reduce the transportation of eroded sediment to wetlands, streams, lakes, drainage systems, and adjacent properties. Erosion and sediment control measures should be implemented and these measures should be in general accordance with local regulations. At a minimum, the following basic recommendations should be incorporated into the design of the temporary erosion and sediment control features for the site: • Schedule the soil, foundation, utility, and other work requiring excavation or the disturbance of the site soils, to take place during the dry season (generally May through September). However, provided precautions are taken using Best Management Practices (BMP's), grading activities can be completed during the wet season (generally October through April). Given the relatively high fines content and moisture sensitivity of some of the shallow subsurface soils at this site, we expect that wet season grading would add significant cost to the project construction. All site work should be completed and stabilized as quickly as possible. • Additional perimeter erosion and sediment control features may be required to reduce the possibility of sediment entering the surface water. This may include additional silt fences, silt fences with a higher Apparent Opening Size (AOS), construction of a berm, or other filtration systems. • Any runoff generated by dewatering discharge should be treated through construction of a sediment trap if there is sufficient space. If space is limited other filtration methods will need to be incorporated. Permanent erosion control should include the following elements: • Finished grading and compaction to at least 90 percent of the modified proctor in landscaping areas and 95 percent in structural areas. • Permanent surfacing placement (asphalt, concrete, hydroseed, and/or landscape - vegetate exposed soil areas. V Design with community in mind 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 8.1.4 Utilities Utility trenches should be excavated according to accepted engineering practices following OSHA (Occupational Safety and Health Administration) standards, by a contractor experienced in such work. The contractor is responsible for the safety of open trenches. Traffic and vibration adjacent to trench walls should be reduced; cyclic wetting and drying of excavation side slopes should be avoided. Depending upon the location and depth of some utility trenches, groundwater flow into open excavations could be experienced, especially during or shortly following periods of precipitation. In general, loose to medium dense silty and sandy soils were encountered at shallow depths in the borings at the site. These soils have variable cohesion and have a tendency to cave in excavations. Shoring or sloping back trench sidewalls is required within these soils. Dewatering may be required depending on the season in which the construction takes place. All utility trench backfill should consist of imported structural fill or suitable*on-site material. Utility trench backfill placed in or adjacent to buildings and exterior slabs should be compacted to at least 95 percent of the maximum dry density based on ASTM Test Method D 1557. The upper 5 feet of utility trench backfill placed in pavement areas should be compacted to at least 95 percent of the maximum dry density based on ASTM Test Method D1557. Below 5 feet, utility trench backfill in pavement areas should be compacted to at least 90 percent of the maximum dry density based on ASTM Test Method D1557. Pipe bedding should be in accordance with the pipe manufacturer's recommendations. The contractor is responsible for removing all water -sensitive soils from the trenches regardless of the backfill location and compaction requirements. The contractor should use appropriate equipment and methods to avoid damage to the utilities and/or structures during fill placement and compaction procedures. 8.1.5 Temporary Shoring Considerations Placement of SSMH-1 will require excavations on the order of 20 feet. The soil conditions are generally loose to medium dense, potentially becoming dense at depth. Groundwater will likely be encountered about 6 feet below existing grade, extending to depths below the excavation. Temporary shoring will be necessary in excavations north of 1-405 and the termination of the pipe ramming/auger boring. Temporary shoring could include interlocking sheet piles with braces, soldier pile walls with lagging, or trench boxes. Significant de -watering should be anticipated and should be considered when selecting a method of shoring. Placement of SSMH-9 will require excavations on the order of 20 feet. The soil conditions at DC- 36, which is the closest boring, include approximately 9 feet of medium dense (becoming loose) silty -sand with gravel. This layer is underlain by approximately 1.5 feet of very soft (0 blow count) sandy silt (possible perched groundwater). The silt layer is underlain by approximately 12 feet of 17 Des�gn VAh comm,x it in min 1 5 GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 very loose to medium dense poorly graded sand with gravel. The sand is underlain by sandstone which should be considered hard for excavation purposes. These soil conditions indicate that temporary shoring will be necessary. Interlocking shoring or deep soldier piles should be considered. Trench box placement may be possible; however, we anticipate that adjacent areas may subside due to excavation caving to the sides of the shoring boxes. This caving would likely make shoring removal nearly impossible. Placement of SSMH-8 will require excavations of nearly 30 feet. The soil conditions at MW-3 and DC-38, which are the closest borings to this location, include approximately 7 feet of medium dense (becoming very dense) silty -sand with gravel. These soils are underlain by a 5 to 10 feet thick transitional zone between silty -sands (highly weathered sandstone) and slightly weathered to unweathered sandstone with local siltstone. The sandstone should be considered hard for excavation purposes and will require removal through blasting, breaking/chipping, coring, or drilling and excavation. If personnel will enter the excavation to the proposed manhole depth, temporary shoring will be necessary. This could include shoring boxes or augered piles with lagging. If no personnel will enter the excavation, the upper 7 to 10 feet could be sloped to a 1 H:l V angle and the sandstone maybe excavated to a vertical angle. Groundwater maybe encountered near the bottom of this excavation. 8.1.6 Groundwater Influence on Construction Groundwater elevation data indicates that groundwater is present below the proposed alignment at depths ranging from 10 to 35 feet below existing elevations. Groundwater appears to be located within Vashon Recessional Outwash east of Shattuck Avenue South and within sandstone deposits (Renton Formation) west of Shattuck Avenue South. The data indicates that groundwater fluctuates between 3 and 12 feet between the high and low levels. Perched groundwater is likely present at shallow elevations throughout the site area, primarily during the wetter periods of the year. Groundwater appears to flow west-northwest and east-northeast from the top of the ridge near Davis Avenue South and generally toward the north along Smithers Avenue South. Groundwater contours and interpreted gradient direction can be found in Figure 6. A review of several bail tests indicates significant groundwater recharge in the deeper groundwater regime, specifically in the area of Smithers Avenue South to South Renton Village Place. We anticipate that perched groundwater has locally developed within the Recessional Outwash. A more regional aquifer appears to be present between the Recessional Outwash and underlying sandstone, extending within the sandstone. In Design with community in mind (C� GEOTECHNICAL INVESTIGATION TALBOT HILL SEWER PROJECT August 13, 2015 We anticipate the need for temporary groundwater de -watering in excavations east of SSMH 4, extending along the Smithers Avenue South alignment to South Renton Village Place. Depending on the season in which construction occurs, de -watering may be necessary in excavations between SSMH-5 (Whitworth Avenue South) and SSMH-4 (Morris Avenue South) and in excavations at SSMH-8 and SSMH-9. Significant de -watering or placement of water -tight (as feasible) shoring should be anticipated in excavations north of 1-405. In this area, groundwater is present from 5 to 6 feet below grade (anticipated seasonal high level) and 7 to 9 feet below grade (anticipated seasonal low level). Excavations in this area are up to 20 feet below existing grades. We can provide input for de -watering design methods upon request. 9.0 Groundwater Elevation Monitoring Groundwater elevation data will be periodically collected through the end of 2015 from accessible and applicable monitoring wells. At a minimum, we will monitor the additional wells placed in June 2015 and update the groundwater figure as needed. 10.0 Closure This report was prepared for the exclusive use of the City of Renton and their appointed consultants.

After reviewing with Stantec, we only pared down the budget slightly from the original. The City feels strongly that the effort shown by Stantec reflects the needs for the project work and we are recommending that WSDOT accept this revised effort. Stantec has provided more detailed explanations to each of your comments and the City has discussed each of those in detail with Stantec. You also previously asked who will execute the agreement between the City and WSDOT, our City Attorney has determined that Gregg Zimmerman can sign the agreement document. Please let me know if you need anything additional at this point. Thanks, Dave C. From: Waligorski, Erik [mailto:erik.waligorski@stantec.com] Sent: Thursday, January 23, 2014 3:42 PM To: David Christensen Subject: RE: I-405 IC/DC Project -Consultant Proposal for Sewer Analysis Dave, Thank you for forwarding the comments from the WSDOT project team. I have taken their comments into consideration and have made some adjustments to the proposed budget for the alternatives analysis. My responses and modifications are as follows: With regard to the overall budget for Task 204 Alternatives Analysis, please consider that this analysis includes two trenchless routes that must be evaluated. As you, and I am sure WSDOT understand, there is inherent risk in trenchless construction. As such, we have brought Staheli Trenchless Consultants on board to provide analysis with regard to the trenchless portions of this project. Approximately $31,000 has been earmarked for trenchless analysis at this stage of the project. Completing this analysis is critical to making an informed decision on the preferred alternative and this information will not need to be duplicated as we move into design. I am in agreement with the review comments that the environmental and permitting requirements will be similar, if not the same for each alternative. I did not expect to have separate analyses of each alternative with regard to these factors. As such, I have only identified 16 hours for our environmental and permitting lead to identify these requirements for all alternatives, along with 2 hours of oversight from the Project Engineer. I are not comfortable reducing these hours for this project. I have made modifications to the scope and budget so that it does not appear as though we are duplicating this effort for each alternative. Thank you for supplying the necessary research for the road restoration of Talbot Rd. This information will be vital to determining the costs associated with the third alternative. As such, I have removed that task from our scope and budget. With regard to the BODR, I agree that the BODR is, in general, a summary of the TM's that were previously generated during the analysis. Where I have budgeted time for this task is to make any revisions to the TM's and to pull together the overall summary that creates the BODR. Please note that, except in the special case of the geotechnical report, we do not submit draft and final TM's during each task. Any revisions made to the TM's based on review comments are not made until the BODR task. That is why there is time shown for the BODR. I have made some reduction is overall hours, but a not willing to reduce these hours beyond what is shown. The time shown is split between my Project Engineer, his engineer -in -training, and our permitting and hydraulic modeling specialists and we feel that it represents an appropriate level of effort to prepare a quality BODR. As you know, we are not one of those firms that bills to the final penny. If we are able to accomplish this analysis for less budget than is estimated, we will not bill that remaining budget. Please let me know if you have any questions regarding the revised scope and budget.

Thanks, Dave C. From: Ross Fenton [ma iIto: Ross. Fenton-consultant@i405.wsdot.wa.gov] Sent: Wednesday, January 22, 2014 1:02 PM To: David Christensen Cc: Robert Kutrich Subject: RE: I-405 IC/DC Project -Consultant Proposal for Sewer Analysis Dave — I have reviewed the provided scope and budget with 1-405 management. The scope is more than I originally envisioned in that it takes the process one step beyond the analysis and develops the selected alternative to a 20% design. However, after discussing this internally, we concur with including the 20% design in this phase as it is work that will need to be done before the final design is complete and it should also validate the feasibility of implementing the selected alternative. The budget looks a little heavy, especially the alternatives analysis task at $78,200, and we request that Stantec revisit it to see if it can be trimmed somewhat. Items that I identified include the following: 204 Alternatives Analysis • Identify environmental issues for each alternative — it appears this task needs only to be performed once, not once for each alternative. • Identify permit requirements for each alternative — it appears this task needs only to be performed once, not once for each alternative. • Research pavement restoration for each alternatives — see attached PDFs with copies of SR 515/Talbot Road roadway paving section used for recently constructed 1-405 Renton Stage Widening and SR 515 Interchange project. 205 Basis of Design Report • Prepare Basis of Design Report — 64 hours (44 + 20) for text, when I assume much of this will already be documented in earlier tech memos. Please, adjust the budget as appropriate, and then resubmit to us. Once we have the final pieces, we will prepare the final agreement and then submit to you for City signatures. Will this agreement need to go through Council for mayor signature?

I do have Stantec's update on where we are. You may recall, we were delayed on our end waiting for geotechnical information from the WSDOT side, that along with the decision to dig a little deeper on the analysis side has delayed us. The good news from that is we should be able to get through design quicker, once we select an alternative. At this time Stantec anticipates completion of the alternatives analysis by end of September, including Workshop #2, then the basis for design being completed in November. On my end, I had not been pushing too hard as I was under the impression that there was not construction dollars at this time. Since our last meeting and an understanding of WSDOT's timing Stantec and the City are looking to expedite this work as best we can. As I mentioned above, I think we can shave some time on the design side based upon level of effort for the alternatives analysis. Please let me know if you have any additional questions. Dave C.

David Christensen From: Waligorski, Erik [erik.waligorski@stantec.com] Sent: Friday, August 15, 2014 7:32 AM To: David Christensen Cc: Brodahl, Erik Subject: RE: Talbot Hill Sewer Relcation (SR167/1405 IC/DC Project) Meeting Dave As you are aware, we are behind the original schedule that we had hoped to follow when we scoped the project. We had hoped to have the geotechnical desk study completed in April of this year, but that was dependent on receiving the geotechnical information from WSDOT within that timeframe. In reality, we did not receive the first set of bore hole data from WSDOT until the middle of June and the second set of bore hole data until mid -July. Once we had received the data from WSDOT we were able to complete the draft geotechnical desk study on August 61h. I will provide that to the City today though our UP site. Based on our meeting this week, we are finalizing the alternative maps and will be providing those, along with the geotechnical desk study to Staheli Trenchless today as well. This will allow them to complete their trenchless analysis for the alternatives. Based on the delay created by the geotechnical data, I anticipate that we will have the alternatives analysis completed by the end of September and the Basis of Design Report by the end of November.

We are asking for relief from the requirements of the Renton Municipal Code, Title VIII — Health Sanitation — Chapter 7 and Noise Level Regulations, as per section 8-7-2 and the Washington State Administration Code (WAC) Chapter 173-60, allowing the City's contractor to work at night. The project is planned to commence May, 2016 and be completed by September, 2017. Project Narrative: The project is located south and east of 1-405, north of S 15th Street and west of Smithers Avenue S. Washington State Department of Transportation is constructing the 1-405 / SR- 167 Direct Connector project. As they expand the highway limited access right-of-way south, the public utilities that serve the residential neighborhood in the Talbot Hill area need to be relocated. The majority of the utilities will be relocated as part of WSDOT's design build project. Because of timing issues WSDOT is contracting with the City of Renton to relocate the Sanitary Sewers under their project. The sanitary sewer needs to be relocated first (because of depth) prior to the relocation of the Olympic Pipeline, which needs to be relocated in order to clear the way for WSDOT to construct their project. As part of the sanitary sewer relocation, there will be two portions of the project that will not utilize typical open cut construction practices. There will be approximately 800 feet of sewer main installed in an east -west direction (from Whitworth to the west) parallel with and along the southern boundary of the 1-405 right-of- way utilizing horizontal directional drilling (HDD). This method was chosen over open cut because the sewer line will be 40'-50' deep. There will also be about 240 feet of sewer main installed under 1-405 to the north that will be installed by guided pipe ram in lieu of open cutting the highway. The remaining portions of the sewer relocation will be accomplished by standard open cut method. hAfile sys\wwp - wastewater\wwp-27-03812 talbot hill sanitary sewer relocation\noise variance\noise variance request.docx Addressee Name Page 2 of 3 Date of Memo Here Special Circumstances: Renton is not specifically scheduling to do night work for the sanitary sewer relocation. However, when doing horizontal directional drilling (HDD) as needed for a portion of this project, "momentum" is everything. Once you have begun a specific task in the process (ie. pulling the pipe), you cannot effectively stop the task and restart. To stop and start a task such as pulling the pipe would have a high risk of failure in completing said task and would not be considered an acceptable means of construction. To stop the task would create difficulties and hardship in a couple of ways. First, it is difficult to overcome the inertia and friction to restart the task. Second, undue delay increases the probability of borehole instability which can add significant installation forces that decrease the probability of pulling in the product pipe successfully. The plan is and every effort will be made to do the work between the hours of 7:00 am to 10:00 pm. However, during specific tasks related to the HDD (ie. pulling the pipe), if they run into problems or the work is proceeding slower than anticipated they will have to continue the work until the task is completed, even if that means continuing past 10:00 pm. For this project, we are having about 800 feet of 12" sewer main installed by HDD. That 800 feet of pipe needs to be pulled into place as one continuous task. It could go in easily and the task would be completed in a normal working day or they could run into difficulties and the task will continue into the night. Most of the noise will be confined to the two entry / exit points on either end of the HDD. There will be the need to continually move the "mud" (the material used to lubricate and cool the drill head, casing and pipe during the processes and stabilize the borehole) from the receiving pit back to the entry pit so the area between the pits would be subject to the truck noise Table 1.

The other mitigation measures listed can be considered part of a best management practice plan. • Constructing a 16-foot tall noise wall around the perimeter of the portal site. The truck/equipment entrance will be placed to face away from houses and would not require a barrier • Give at least 72 hour advance notice to nearby residents of the time periods when particularly noisy work and potential nighttime construction activities (e.g. pullback) will be occurring through mailers, door hangers, or other similar notification methods. • Create and utilize a noise mitigation training program, which shall be implemented for all field -worker supervisory personnel including sub -contractor supervisors. (Required in construction contract.) • Take noise level readings. At a minimum, the contractor will be required to take a base noise level reading before the start of construction activities, at the start of the drilling, and after noise mitigation measures have been installed. • Equip all vehicles with ambient sensitive backup warning devices. The Contractor may use back-up observers in lieu of back-up warning devices for all equipment except dump trucks in compliance with WAC Chapter 296-155-610 and 296-155-615. The Contractor shall use back-up observers and back-up warning devices for dump trucks in compliance with WAC Chapter 296-155-640. Alternative Nighttime Noise Mitigation Measures If the above measures are determined to be insufficient, the following measures may also be implemented in an attempt to reduce the construction noise levels. • Using acoustical blankets, pads, and/or boards to control metal -on -metal clanging noise or other banging noises that can occur while picking up drill pipe and setting on racks; moving the drill pipe from pipe racks, and making up the drill pipe. • Offer to relocate the nearest residents during nights when construction activities would occur (e.g., during pullback) or during days with particularly noisy daytime activities (e.g., casing installation). hAfile sys\wwp - waste water\wwp-27-03812 talbot hill sanitary sewer relocation\noise variance\noise variance request.docx k DEPARTMENT OF COMMUNITY CITY OF AND ECONOMIC DEVELOPMENT Renton Planning Division LAND USE PERMIT MASTER APPLICATION PROPERTY OWNER(S) NAME: Washington State Department of Transportation / City of Renton ADDRESS: WSDOT: 600 1081h Ave NE, Suite 405 Renton: 1055 S Grady Way CITY: Bellevue ZIP: 98004 Renton 98057 TELEPHONE NUMBER: APPLICANT (if other than owner) NAME: COMPANY (if applicable): ADDRESS: CITY: ZIP: TELEPHONE NUMBER.

However, when doing horizontal directional drilling (HDD) as needed for a portion of this project, "momentum" is everything. Once you have begun a specific task in the process (ie. pulling the pipe), you cannot effectively stop the task and restart. To stop the task would create difficulties and hardship as it would be highly likely that we could not overcome the inertia and friction to restart the task. The plan is and every effort will be made to do the work between the hours of 7:00 am to 10:00 pm. However, during specific tasks related to the HDD (ie. pulling the pipe), if they run into problems or the work is proceeding slower than anticipated they will have to continue the work until the task is completed, even if that means continuing past 10:00 pm. For this project, we are having about 800 feet of 12" sewer main installed by HDD. That 800 feet of pipe needs to be pulled into place as one continuous task. It could go in easily and the task would be completed in a normal working day or they could run into difficulties and the task will continue into the night. Most of the noise will be confined to the two entry / exit points on either end of the HDD. There will be the need to continually move the "mud" (the material used to lubricate and cool the drill head, casing and pipe during the process and stabilize the borehole) from the receiving pit back to the entry pit so the area between the pits would be subject to truck noise as they haul this material from the receiving point back to the entry point. • The granting of the variance will not be materially detrimental to the public health or injurious to the property or improvements in the vicinity and zone in which subject property is situated. The noise would occur during a maximum 10 non-consecutive nights over the course of 17 months. The relocation of the sanitary sewers would allow for the continued provision of a public health service to the residents of Talbot Hill as the State performs the needed transportation improvements to the highway system. When distance is incorporated into the assessment as well as topography and the proposed mitigation measures, we estimate that the nearest residences would still notice the nighttime work but not as severe as without all the listed mitigation. Citizens will be impacted to the minimum extent and there is no possibility that the public health or safety will be diminished. If any noise related complaints are received, the contractor along with the City will work with the complainant to attempt to resolve the issue(s). • The approval of this variances shall not constitute a grant of special privilege consistent with the limitation upon uses of other properties in the vicinity and zone in which the property is situated. The City sanitary sewer facilities need to be moved to make room for the transportation project. The State is contracting with the City to have them relocated. To maintain grade, the primary run of sewer needs to be between 40' and 50' deep. To use open excavation construction at those depths would cause major disruption to the neighborhood. Using horizontal directional drilling will, most likely, shorten the time it takes to install the new sewer and provide less continuous disruption to the area. The potential downside to choosing this method in order to minimize the overall disruption is to possibly have some nights where they cannot stop work and have to continue past 10:00 PM. As stated above, we are not scheduling to do night work and we would be happy to not have to use any of the requested nights. Our planned scenario is that work starts in May 2016, we use 0 to 4 nights in June or July 2016, and the majority of our work is completed by January 2017. However, as with any major construction project we are planning for contingencies. • The approval is the minimum variance that will accomplish the desire purpose. The requested non-consecutive days are the minimum number of nights required to complete this work including planning for potential construction contingencies. PROJECT NARRATIVE 1-405 / SR-167 Direct Connect - Sanitary Sewer Relocation Washington State Department of Transportation is constructing the 1-405 / SR-167 Direct Connector project. As they expand the highway limited access right-of-way south, the public utilities that serve the residential neighborhood in the Talbot Hill area need to be relocated. WSDOT is responsible for the relocation of the utilities. Because of timing and coordination issues, the State needs the sanitary sewers relocated prior to their contractor mobilizing onto the site. WSDOT is contracting with the City of Renton to relocate the sewers. The general location of the sewer relocation project is a triangular area bounded by 1-405, Smithers Ave S, and S 15th St. As a sub work of the WSDOT project, the sanitary sewer relocation will be done under WSDOT's permits. The land use designation for the area Residential — Medium Density and is currently zoned Residential - 6 DU/AC and Residential - 8 DU/AC. The area where the new sewers (and other utilities) will be located will be City right-of-way and the area north would become State Limited Access Right -of -Way. There are not any plans to change the land use or zoning designations in the area as part of these projects. There are steep slopes in the area that will be dealt with under the permitting for the parent WSDOT project. There is one wetland identified in the sanitary sewer construction zone. This is identified in WSDOT's JARPA permit as Wetland 2.6R which is 6,424 sqft category 111. WSDOT's proposal is that there will be permanent impact to the wetland due to a proposed earthen berm. The sewer main will be installed through the southern edge or just to the south of the wetland. In the area, subsurface soils consist of loose to medium dense silty -sand and poorly graded sand with silt and variable amounts of gravel. Drainage in the area appears to be free flowing except in the vicinity of the wetland discussed above. As part of our project, WSDOT is having the City of Renton set the basic grade of the new S 14th St / utility corridor which will entail some cut and fill. This is part of the overall regrade WSDOT is planning to do for their project. The fill needs to go in after the sewer is installed but prior to the WSDOT construction as another utility has to relocate into the corridor prior to the State's contractor coming on site to complete the road. For our portion of the project, we are estimating approximately 1600 cy of cut & 3400 cy of fill. Total estimated cost for the sanitary sewer relocation is $5,000,000 The sewer relocation contractor may have a job shack on site. As part of the sanitary sewer relocation, there will be two portions of the project that will not utilize typical open cut construction practices. There will be approximately 800 feet of sewer main installed in an east -west direction (from Whitworth to the west) parallel with and along the southern boundary of the new 1-405 right-of-way utilizing horizontal directional drilling. This method was chosen over open cut because the sewer line will be 40'-50' deep. There will also be about 240 feet of sewer main installed under 1-405 to the north that will be installed by guided pipe ram in lieu of open cutting the highway. The remaining portions of the sewer relocation will be accomplished by standard open cut method. The only part of the project that we are considering as might needing night work is the 800 feet of sewer main being installed by the horizontal directional drill. Proposed Nighttime Noise Mitigation Measures To limit the potential effect of construction -related noise at the residences near the HDD portal sites, several noise mitigation measures have been considered. The other mitigation measures listed can be considered part of a best management practice plan. • Constructing a 16-foot tall noise wall around the perimeter of the portal site. The truck/equipment entrance will be placed to face away from houses and would not require a barrier • Give at least 72 hour advance notice to nearby residents of the time periods when particularly noisy work and potential nighttime construction activities (e.g. pullback) will be occurring through mailers, door hangers, or other similar notification methods. • Create and utilize a noise mitigation training program, which shall be implemented for all field -worker supervisory personnel including sub -contractor supervisors. (Required in construction contract.) • Take noise level readings. At a minimum, the contractor will be required to take a base noise level reading before the start of construction activities, at the start of the drilling, and after noise mitigation measures have been installed. • Equip all vehicles with ambient sensitive backup warning devices. The Contractor may use back-up observers in lieu of back-up warning devices for all equipment except dump trucks in compliance with WAC Chapter 296-155-610 and 296-155-615. The Contractor shall use back-up observers and back-up warning devices for dump trucks in compliance with WAC Chapter 296-155-640. Alternative Nighttime Noise Mitigation Measures If the above measures are determined to be insufficient, the following measures may also be implemented in an attempt to reduce the construction noise levels. Using acoustical blankets, pads, and/or boards to control metal -on -metal clanging noise or other banging noises that can occur while picking up drill pipe and setting on racks; moving the drill pipe from pipe racks, and making up the drill pipe. Offer to relocate the nearest residents during nights when construction activities would occur (e.g., during pullback) or during days with particularly noisy daytime activities (e.g., casing installation). hAfile sys\wwp - wastewater\wwp-27-03812 talbot hill sanitary sewer relocation\noise variance\proposed mitigation.docx .00 S 151h St Roffiny /1,11, 300 'Feet 1-405 FWY its ,■ Panthe Creek ds Wetlands : W j�, ■ 0 IN ---------- - ■ 0 100 200 400 Feet 1 1 1 1 1 1 1 1 1 3p0vect 1-405 FWY S 15th St — Panth e 1 �� Creek Wetlands +11 AP/-J S 15th St 16 In , ■ I N ■ 0 100 200 400 Feet DEPARTMENT OF COMMUNITY D c;; yof AND ECONOMIC DEVELOPMENT HEARING EXAMINER PUBLIC HEARING April 12, 2016 AGENDA COMMENCING AT 11:00 AM, COUNCIL CHAMBERS, 7TH FLOOR, RENTON CITY HALL The application(s) listed are in order of application number only and not necessarily the order in which they will be heard.

Project Summary: The City of Renton, Wastewater Utility requests a variance from RMC 8-7-2 (Noise Regulations, Maximum Environmental Noise Levels) in order to conduct construction work at night in an area with residential uses. The construction work would occur during 10 non-consecutive nights of construction from May 1, 2016 through September 30, 2017, to allow for relocation of sewer, due to the Washington State Department of Transportation (WSDOT) 1-405/SR-167 Direct Connect Project. The sewer relocation project is located south and east of 1-405, north of South 15th Street and west of Smithers Avenue South along South 14th Street. The project includes work and improvements within the City of Renton and within the State Department of Transporation Right of Way limits. Noise levels resulting from project construction activity would generate peak noise levels of 76 to 88 dBA as perceived at a distance of 50 feet from the proposed sewer main alignment. A variance from RMC 8-7-2 is necessary in order to conduct the nighttime work, as maximum permissible environmental noise levels (per WAC 173-60-040, incorporated by reference in RMC 8-7) limit extended periods of noise from 10:00 pm to 7:00 am to levels between 45 dBA and 60 dBA, with exceedances of 5 to 15 dBA permitted for periods of 1.5 to 15 minutes in any one -hour period (WAC 173-60-040).

PROJECT DESCRIPTION/BACKGROUND: The City of Renton (COR) requests a variance from RMC 8-7-2 (Noise Regulations, Maximum Environmental Noise Levels) in order to conduct construction work at night in an area with residential uses. The construction work would occur over 10 non-consecutive nights from May 1, 2016 to September 30, 2017. Washington State Department of Transportation (WSDOT) will begin construction of the 1-405 / SR-167 Direct Connector project later this year. As a result of the proposed expansion of the highway limited access right-of-way, the public utilities that serve the residential neighborhood in the Talbot Hill area will need to be relocated. WSDOT is responsible for the relocation of the utilities. Because of the timing and coordination issues, the State has requested the sanitary sewer be relocated prior to their contractor mobilizing onto the site. WSDOT is contracting with the City of Renton to relocate the sewers. The project would consist of a trenchless method of pipe installation called horizontal directional drill (HDD). This methodology would be used to install approximately 800 lineal feet of the total 1,600 lineal feet of sewer main to be relocated. Construction equipment used during the nighttime operations will include, but is not limited to: dump trucks, generators, portable lighting (light plants), excavators, loaders, mud pumps, drill rig that conducts the horizontal directional drilling (HDD) and a separation plant. Noise levels resulting from the project construction activity would generate peak noise levels of 76 to 88 dBA as perceived at a distance of 50 feet from the proposed pipe alignment. To limit the potential effect of construction -related noise at the residences near the HDD portal sites, several noise mitigation measures have been considered. • Construction of a 16-foot tall noise wall around the perimeter of the portal site. The truck/equipment entrance will be placed to face away from houses and would not require a barrier • Give at least 72 hour advance notice to nearby residents of the time periods when particularly noisy work and potential nighttime construction activities (i.e. The Pilot Bore, Reaming or Pipe Installation) will be occurring through mailers, door hangers, or other similar notification methods. • Create and utilize a noise mitigation training program, which shall be implemented for all field - worker supervisory personnel including sub -contractor supervisors. (Required in construction contract.) • Take noise level readings. At a minimum, the contractor will be required to take a base noise level reading before the start of construction activities, at the start of the drilling, and after noise mitigation measures have been installed. • Equip all vehicles with ambient sensitive backup warning devices. The Contractor may use back-up observers in lieu of back-up warning devices for all equipment except dump trucks in compliance with WAC Chapter 296-155-610 and 296-155-615. The Contractor shall use back-up observers and back-up warning devices for dump trucks in compliance with WAC Chapter 296-155-640. • When feasible, temporary noise shields would be placed around construction equipment and trucks will not be allowed to park or idle near residences. • An after-hours noise complaint phone number will be provided to the local residents to register complaints to be mitigated. • Alternative mitigation measures include using acoustical blankets, pads, and/or boards to control metal -on -metal clanging noise or other banging noises that can occur while picking up drill pipe and setting to and from the storage racks; and offering to relocate the nearest residents during nights when construction activities would occur (i.e. The Pilot Bore, Reaming or Pipe Installation) or during days with particularly noisy daytime activities.

FINDINGS: Having reviewed the written record in the matter, the City now makes and enters the following: 1. Request: Noise Variance from RMC 8-7-2 (Maximum Environmental Noise Levels) for work between 10:00 pm and 7:00 am over 10 non-consecutive nights from May 1, 2016 to September 30, 2017. 2. Variance: The proposal requires a public hearing with the Hearing Examiner. 3. Existing Land Uses: Single family residences 4. Zoning: Residential — 6 Dwelling Units per Acre (R-6), Residential — 8 Dwelling Units per Acre (R-8) E. CONSISTENCY WITH VARIANCE CRITERIA: Section 8-7-8.D. Lists 7 criteria that the Hearing Examiner is asked to consider, along with all other relevant information, in making a decision on a Noise Variance application. These include the following: The Hearing Examiner shall have authority to grant a variance upon making a determination, in writing, that the conditions specified below have been found to exist: 1. That the applicant suffers practical difficulties and unnecessary hardship and the variance is necessary because of special circumstances applicable to the applicant's property or project, and that the strict application of this Chapter will deprive the subject property owner or applicant of rights and privileges enjoyed by others. Staff Analysis: COR is not specifically scheduling to do night work for the sanitary sewer pipe relocation, however, when conducting horizontal directional drilling (HDD) needed for the 800 lineal feet portion of this project, "momentum" is key. Once you have begun one of the three steps involved in the process (i.e. The Pilot Bore, Reaming or Pipe Installation), you cannot efficiently stop the task and restart at a later time. To stop the step prior to completion would create difficulties and hardship as it would be highly likely that the contractor could not overcome the inertia and friction to restart the task. The plan is and every effort will be made to do the work between the hours of 7:00 am to 10:00 pm. However, during specific steps related to the HDD (i.e. The Pilot Bore, Reaming or Pipe Installation), if the contractor runs into problems or the work is proceeding slower than anticipated they will need to continue the work until the specific step is completed, even if that means continuing past 10:00 pm. For this portion of the project, the COR proposes to install about 800 feet of 12-inch sewer main installed by HDD method. That 800 feet of pipe needs to be pulled into place as one continuous task. The installation process could go easily and the task could be NOISE VARIANCE HEX REPORT SEWER RELOCATION Crty of Renton Department of Community & Economic Development NOISE VARIANCE HEX REPORT SEWER RELOCATION 1-4051SR-167 DIRECT CONNECTOR SEWER RELOCATION PROJECT LUA16-000212, V-H Report of April 6, 2016 Page 5 of 7 completed in a normal working day or the contractor may run into difficulties and the specific step would need to continue into the night. The majority of the noise will be confined to the two entry / exit points on either end of the HDD. There will be the need to continually move the "mud" (the material used to lubricate and cool the drill head, casing and pipe during the process and stabilize the borehole) from the receiving pit back to the entry pit so the area between the pits would be subject to truck noise as they haul this material from the receiving point back to the entry point. 2. That the granting of the variance will not be materially detrimental to the public health, welfare or safety, or unduly injurious to the property or improvements in the vicinity of the location for which this variance is sought. Staff Analysis: The noise from the HDD construction method would occur during a maximum of 10 non-consecutive nights over the course of 17 months. The relocation of the sanitary sewers would allow for the continued provision of a public health service to the residents of Talbot Hill as the State performs the needed transportation improvements to their highway system. When distance is incorporated into the assessment as well as topography and the proposed mitigation measures, we estimate that the nearest residences would notice the nighttime work but not as severe as without the listed mitigation measures. Citizens will be impacted to the minimum extent possible and there is no likelihood that the public health or safety will be diminished. If any noise related complaints are received, the contractor along with the City will work with the complainant to resolve the issue(s). Staff posted and mailed a notice to all residents within a 300 feet radius of the project corridor. No comments have been received. 3. That the variance sought is the minimum variance which will accomplish the desired purpose. Staff Analysis: The work would occur over 17 months on 10 non-consecutive nights. The work would impact approximately 800 lineal feet. Mitigation measures are proposed by the applicant to diminish the impact on the surrounding area. Staff believes that the request is the minimum number of nights required to complete this portion of the relocation project including any major construction contingencies to the critical path needed to accomplish the necessary pipe installation. 4. That the variance contains such conditions deemed to be necessary to limit the impact of the variance on the residence or property owners impacted by the variance. The variance approval may be subject to conditions including, but not limited to, the following: a. Implementation of a noise monitoring program; b. Maximum noise levels; c.

Staff Analysis: Noise shields will be used as directed by the engineer and when feasible. Back-up beepers will be ambient sensitive backup alarms, and truck tailgate banging will not be allowed. An after-hours noise complaint phone number staffed by the City of Renton Wastewater Department and or their contractors will be provided. Staff recommends as a condition of approval that the Wastewater Department provide the City's project manager with the after-hours noise complaint phone number and a summary of any complaints and the response provided, within 2 days of receiving the complaint. In addition, staff recommends that the applicant provide notice to the City's project manager of the dates of expected night work, a minimum of 24 hours in advance of the work. S. The importance of the services provided by the facility creating the noise and the other impacts caused to the public safety, health and welfare balanced against the harm to be suffered by residents or property owners receiving the increased noise permitted under this variance. Staff Analysis: The State Highway system, in and through the City of Renton, is heavily travelled and improvements to this system outweigh the limited -term noise impacts to residents and property owners. Additionally, the residents of the City also deserve continued service from the City's Wastewater Department to dispose of household wastes. The applicant has identified measures to be implemented to reduce excessive noise. Impacts are further mitigated by the existing ambient noise level emanating from the 1-405 corridor just to the north of the proposed sewer alignment.

The availability of practicable alternative locations or methods for the proposed use which will generate the noise. Staff Analysis: The work is a relocation of sewer pipe due to the expansion of the 1-405 and SR- 167 corridor transportation project funded by the State Legislature. Various alternative alignments for the pipe location were considered and this was the final alternative agreed upon between the COR and WSDOT. 7. The extent by which the prescribed noise limitations will be exceeded by the variance and the extent and duration of the variance. Staff Analysis: The work of installing 800 lineal feet (per the HDD method versus the open cut method) of the total 1,600 lineal feet of pipe would occur over a 17 month period on 10 non- consecutive days. F. CONCLUSIONS: THE SUBJECT SITE IS LOCATED WITHIN PROPERTIES OWNED BY THE CITY OF RENTON AND WSDOT. THE PROPOSED PIPE LALIGNMENT IS LOCATED ALONG S. 14T" STREET BETWEEN S. 15T" STREET AND SMITHERS AVENUE S. THE WORK WOULD OCCUR OVER 5 MONTHS ON 10 NON- CONSECUTIVE NIGHTS. 1. The work requires a variance from RMC 8-7-2 (Noise Regulations, Maximum Environmental Noise Levels) as levels of noise for night time would be exceeded. 2. Analysis of the proposal according to variance criteria of RMC 8-7-8-D is found in the body of the Staff Report. G. RECOMMENDATION: Staff recommends that the Variance for the 1-405/SR-167 Direct Connect Sanitary Sewer Relocation, File No. LUA16-000212, V-H be approved subject to the following conditions: The applicant shall provide the City of Renton project manager with the phone number for after-hours noise complaints prior to commencement of construction. Any complaints from within the Renton city limits will be summarized and reported to the City's project manager within 2 days of the complaint. 2. The applicant shall implement proposed mitigation measures and alternate mitigation measures to diminish or eliminate noise during construction. 3. The applicant shall notify the City of Renton project manager with the date and areas of expected night work prior to commencement of night work, a minimum of 24 hours in advance of the work. NOISE VARIANCE HEX REPORT SEWER RELOCATION PUBLIC WORKS DEPARTMENT C"y"°f M E M O R A N D U M DATE: February12, 2016 TO: Jennifer Henning,,� FROM: Michael Benoioff) SUBJECT: Noise Variance Request 1-405 / SR-167 Direct Connect Sanitary Sewer Relocation The City of Renton Wastewater Utility is requesting 10 non-consecutive nights of temporary noise variance to complete the relocation of sanitary sewers related to the WSDOT 1-405 / SR-167 Direct Connect project. We are asking for relief from the requirements of the Renton Municipal Code, Title VIII — Health Sanitation — Chapter 7 and Noise Level Regulations, as per section 8-7-2 and the Washington State Administration Code (WAC) Chapter 173-60, allowing the City's contractor to work at night. The project is planned to commence May, 2016 and be completed by September, 2017. Project Narrative: The project is located south and east of 1-405, north of S 15th Street and west of Smithers Avenue S. Washington State Department of Transportation is constructing the 1-405 / SR- 167 Direct Connector project. As they expand the highway limited access right-of-way south, the public utilities that serve the residential neighborhood in the Talbot Hill area need to be relocated. The majority of the utilities will be relocated as part of WSDOT's design build project. Because of timing issues WSDOT is contracting with the City of Renton to relocate the Sanitary Sewers under their project. The sanitary sewer needs to be relocated first (because of depth) prior to the relocation of the Olympic Pipeline, which needs to be relocated in order to clear the way for WSDOT to construct their project. As part of the sanitary sewer relocation, there will be two portions of the project that will not utilize typical open cut construction practices. There will be approximately 800 feet of sewer main installed in an east -west direction (from Whitworth to the west) parallel with and along the southern boundary of the 1-405 right-of- way utilizing horizontal directional drilling (HDD). This method was chosen over open cut because the sewer line will be 40'-50' deep. There will also be about 240 feet of sewer main installed under 1-405 to the north that will be installed by guided pipe ram in lieu of open cutting the highway. The remaining portions of the sewer relocation will be accomplished by standard open cut method. hAfile sys\wwp - wastewater\wwp-27-03812 talbot hill sanitary sews EXHIBIT 2 variance\noise variance request.docx Addressee Name Page 2 of 3 Date of Memo Here Special Circumstances: Renton is not specifically scheduling to do night work for the sanitary sewer relocation. However, when doing horizontal directional drilling (HDD) as needed for a portion of this project, "momentum" is everything. Once you have begun a specific task in the process (ie. pulling the pipe), you cannot effectively stop the task and restart. To stop and start a task such as pulling the pipe would have a high risk of failure in completing said task and would not be considered an acceptable means of construction. To stop the task would create difficulties and hardship in a couple of ways. First, it is difficult to overcome the inertia and friction to restart the task. Second, undue delay increases the probability of borehole instability which can add significant installation forces that decrease the probability of pulling in the product pipe successfully. The plan is and every effort will be made to do the work between the hours of 7:00 am to 10:00 pm. However, during specific tasks related to the HDD (ie. pulling the pipe), if they run into problems or the work is proceeding slower than anticipated they will have to continue the work until the task is completed, even if that means continuing past 10:00 pm. For this project, we are having about 800 feet of 12" sewer main installed by HDD. That 800 feet of pipe needs to be pulled into place as one continuous task. It could go in easily and the task would be completed in a normal working day or they could run into difficulties and the task will continue into the night. Most of the noise will be confined to the two entry / exit points on either end of the HDD. There will be the need to continually move the "mud" (the material used to lubricate and cool the drill head, casing and pipe during the processes and stabilize the borehole) from the receiving, pit bark to tho ontry Tait cn tho aroa bot:.teen the pits ::i.ni ld be S'ublect t0 the truck noise Table 1.

The other mitigation measures listed can be considered part of a best management practice plan. • Constructing a 16-foot tall noise wall around the perimeter of the portal site. The truck/equipment entrance will be placed to face away from houses and would not require a barrier • Give at least 72 hour advance notice to nearby residents of the time periods when particularly noisy work and potential nighttime construction activities (e.g. pullback) will be occurring through mailers, door hangers, or other similar notification methods. • Create and utilize a noise mitigation training program, which shall be implemented for all field -worker supervisory personnel including sub -contractor supervisors. (Required in construction contract.) • Take noise level readings. At a minimum, the contractor will be required to take a base noise level reading before the start of construction activities, at the start of the drilling, and after noise mitigation measures have been installed. • Equip all vehicles with ambient sensitive backup warning devices. The Contractor may use back-up observers in lieu of back-up warning devices for all equipment except dump trucks in compliance with WAC Chapter 296-155-610 and 296-155-615 The Contractor shall use back-up observers and back-up warning devices for dump trucks in compliance with WAC Chapter 296-155-640. Alternative Nighttime Noise Mitigation Measures If the above measures are determined to be insufficient, the following measures may also be implemented in an attempt to reduce the construction noise levels. Using acoustical blankets, pads, and/or boards to control metal -on -metal clanging noise or other banging noises that can occur while picking up drill pipe and setting on racks; moving the drill pipe from pipe racks, and making up the drill pipe. Offer to relocate the nearest residents during nights when construction activities would occur (e.g., during pullback) or during days with particularly noisy daytime activities (e.g., casing installation). hAfile sys\wwp - wastewater\wwp-27-03812 talbot hill sanitary sewer relocation\noise variance\noise variance request.docx RECEIVED MAR 17 2016 PROJECT NARRATIVE CITY OF 9 ?•%TON 1-405 / SR-167 Direct Connect - Sanitary Sewer Relocation P. ' Washington State Department of Transportation is constructing the 1-405 / SR-167 Direct Connector project. As they expand the highway limited access right-of-way south, the public utilities that serve the residential neighborhood in the Talbot Hill area need to be relocated. WSDOT is responsible for the relocation of the utilities. Because of timing and coordination issues, the State needs the sanitary sewers relocated prior to their contractor mobilizing onto the site. WSDOT is contracting with the City of Renton to relocate the sewers. The general location of the sewer relocation project is a triangular area bounded by 1-405, Smithers Ave S, and S 15" St. As a sub work of the WSDOT project, the sanitary sewer relocation will be done under WSDOT's permits. The land use designation for the area Residential — Medium Density and is currently zoned Residential - 6 DU/AC and Residential - 8 DU/AC. The area where the new sewers (and other utilities) will be located will be City right-of-way and the area north would become State Limited Access Right -of -Way. There are not any plans to change the land use or zoning designations in the area as part of these projects. There are steep slopes in the area that will be dealt with under the permitting for the parent WSDOT project. There is one wetland identified in the sanitary sewer construction zone. This is identified in WSDOT's JARPA permit as Wetland 2.6R which is 6,424 sqft category III. WSDOT's proposal is that there will be permanent impact to the wetland due to a proposed earthen berm. The sewer main will be installed through the southern edge or just to the south of the wetland. In the area, subsurface soils consist of loose to medium dense silty -sand and poorly graded sand with silt and variable amounts of gravel. Drainage in the area appears to be free flowing except in the vicinity of the wetland discussed above. As part of our project, WSDOT is having the City of Renton set the basic grade of the new S 14'h St / utility corridor which will entail some cut and fill. This is part of the overall regrade WSDOT is planning to do for their project. The fill needs to go in after the sewer is installed but prior to the WSDOT construction as another utility has to relocate into the corridor prior to the State's contractor coming on site to complete the road. For our portion of the project, we are estimating approximately 1600 cy of cut & 3400 cy of fill. Total estimated cost for the sanitary sewer relocation is $5,000,000 The sewer relocation contractor may have a job shack on site. As part of the sanitary sewer relocation, there will be two portions of the project that will not utilize typical open cut construction practices. There will be approximately 800 feet of sewer main installed in an east -west direction (from Whitworth to the west) parallel with and along the southern boundary of the new 1-405 right-of-way utilizing horizontal directional drilling. This method was chosen over open cut because the sewer line will be 40'-50' deep. There will also be about 240 feet of sewer main installed under 1-405 to the north that will be installed by guided pipe ram in lieu of open cutting the highway. The remaining portions of the sewer relocation will be accomplished by standard open cut method. The only part of the project that we are considering as might needing night work is the 800 feet of sewer main being installed by the horizontal directional drill. EXHIBIT 3 RECEIVED MAR 17 2016 Justification for the Noise Variance Request C`^'` -, • The variance is necessary because of special circumstances NLA .-Xi Renton is not specifically scheduling to do night work for the sanitary sewer relocation. However, when doing horizontal directional drilling (HDD) as needed for a portion of this project, "momentum" is everything. Once you have begun a specific task in the process (ie. pulling the pipe), you cannot effectively stop the task and restart. To stop the task would create difficulties and hardship as it would be highly likely that we could not overcome the inertia and friction to restart the task. The plan is and every effort will be made to do the work between the hours of 7:00 am to 10:00 pm.

It could go in easily and the task would be completed in a normal working day or they could run into difficulties and the task will continue into the night. Most of the noise will be confined to the two entry / exit points on either end of the HDD. There will be the need to continually move the "mud" (the material used to lubricate and cool the drill head, casing and pipe during the process and stabilize the borehole) from the receiving pit back to the entry pit so the area between the pits would be subject to truck noise as they haul this material from the receiving point back to the entry point. • The granting of the variance will not be materially detrimental to the public health or injurious to the property or improvements in the vicinity and zone in which subject property is situated. The noise would occur during a maximum 10 non-consecutive nights over the course of 17 months. The relocation of the sanitary sewers would allow for the continued provision of a public health service to the residents of Talbot Hill as the State performs the needed transportation improvements to the highway system. When distance is incorporated into the assessment as well as topography and the proposed mitigation measures, we estimate that the nearest residences would still notice the nighttime work but not as severe as without all the listed mitigation. Citizens will be impacted to the minimum extent and there is no possibility that the public health or safety will be diminished. If any noise related complaints are received, the contractor along with the City will work with the complainant to attempt to resolve the issue(s). • The approval of this variances shall not constitute a grant of special privilege consistent with the limitation upon uses of other properties in the vicinity and zone in which the property is situated. The City sanitary sewer facilities need to be moved to make room for the transportation project. The State is contracting with the City to have them relocated. To maintain grade, the primary run of sewer needs to be between 40' and 50' deep. To use open excavation *:/:M11.311E,I construction at those depths would cause major disruption to the neighborhood. Using horizontal directional drilling will, most likely, shorten the time it takes to install the new sewer and provide less continuous disruption to the area. The potential downside to choosing this method in order to minimize the overall disruption is to possibly have some nights where they cannot stop work and have to continue past 10:00 PM. As stated above, we are not scheduling to do night work and we would be happy to not have to use any of the requested nights. Our planned scenario is that work starts in May 2016, we use 0 to 4 nights in June or July 2016, and the majority of our work is completed by January 2017. However, as with any major construction project we are planning for contingencies. • The approval is the minimum variance that will accomplish the desire purpose. The requested non-consecutive days are the minimum number of nights required to complete this work including planning for potential construction contingencies. Proposed Nighttime Noise Mitigation Measures To limit the potential effect of construction -related noise at the residences near the HDD portal sites, several noise mitigation measures have been considered. The other mitigation measures listed can be considered part of a best management practice plan. • Constructing a 16-foot tall noise wall around the perimeter of the portal site.

Robert sent a draft of this to you on 2/19, which you are reviewing as noted in the below email. This agreement identifies the following: o City Share: $419,509 o State Share: $3,177,286 GCB 2274 - Cooperative Agreement. This document is in with AAG for review. Included in this document, Section 10.0 Payment, is provisions for the State to reimburse the City as follows: 10.1 In consideration for the relocated portions of South 14th Street described in Section 4.3.6 which will not be designed and constructed to City Standards WSDOT will reimburse the CITY a one-time lump sum amount (Reimbursement Amount) of kwrite> Dollars ($xx4 _ This- amount represents_ the estimated cost difference, as shown in Exhibit F, Cost Estimate, between the roadway section if it were constructed to City Standards less the roadway section as it will be constructed by the Project. Application for Temporary Franchise, including Special Provisions for Temporary Franchise o Allows for construction and maintenance of relocated SS on State property until property relinquished and/or transferred to City at completion of 405/167 IC DC Project. City Construction and Maintenance Permit, including Special Provisions (City Construction and Maintenance Permit) o Allows for construction and maintenance of relocated SS within 1-405 limited access. The first two above bulleted items address the reimbursement: • UTB 1223 — addresses Renton responsibility to relocate SS located within 1-405 right of way at City cost. • GCB 2274 — addresses State responsibility for reimbursing Renton for use of street variance for reconstruction of S. 14th at less than City Standards. Note: the reimbursement for the S. 14th work is not tied to the Panther Creek wetlands property, but is tied to the terms contained in Section 10 of the Cooperative agreement. Please, find attached a copy of the 3`d and 41h above bulleted items for your consideration. There is one additional attachment that is proposed for inclusion with each of these two items, which is the environmental commits associated with the work being performed under WSDOT's environmental permits. This document is being cleaned up and will be provided to you in a follow-up email later this week. EXHIBIT 8 Please, let me know if you have questions and/or concerns.

I want to be sure I can express this properly to my Council as I get their approval and can be assured that these costs will be reimbursed. Thanks, Dave C.

The draft is based on a WSDOT standard form. Please distribute for review as needed and have all review comments returned to me. Note that provision 7.2 mentions access and right of entry provisions to be included in Exhibit A. I understand that the plan is to install the settlement monitoring devices within limited access right of way on either side of I- 405 at Smithers, so we will need to prepare language to include in the Specs to address that work.
