The applicant seeks to demolish an existing 999sfbuilding and replace it with a new l ,449sf building. The applicant will also remove substation equipment and create a new storm drainage system. The conditional use permit is approved with conditions. Testimony Angelea Weihs, Associate Planner, summarized the staff report and entered additional exhibits into the record (Ex. 17-19). She noted the City had received comment from Seattle PUD regarding access. In response to the examiner, Ms. Weihs stated the substation was in excess of 460 feet from the nearest residences and that the existing and proposed planting areas will serve as a buffer. Brianne Bannwarth, Development Engineering Manager, stated the project must meet the King County Stormwater Manual. In response to the examiner, Ms. Bannwarth stated all the potential impacts from the project with respect to construction are mitigated within the City's development codes. Ms. Bannwarth stated the City would be amenable to adding a condition of approval requiring the City to set up a call number for construction related concerns. CONDITIONAL USE I 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Kerry Kriner, Planner for PSE, stated the staff report is incorrect in describing the building proposed for demolition as a control house. The building is actually an oil storage building. Ms. Kriner noted PSE had originally applied for a permit in March 2016 and was told the building was exempt from the !BC and therefore did not require a permit. In September, the City of Renton required an electrical permit and then reversed the need for a building permit. In response to the examiner, Jennifer Henning, Planning Director, stated the City had not originally known the building was taller than the maximum height for an accessory structure permitted within the zone. They had originally understood the building was smaller and not as tall. The electrical permit triggered the need for a building permit. The presence of a building permit triggered a conditional use permit because of the use within the zone. Ms. Kriner stated PSE objects to the City's $200,000 frontage improvement requirement and will be submitting a request for a waiver. No modifications or variances are currently at issue. Ms. Kriner stated the applicant had submitted a landscape narrative (Ex. 20). Ms. Henning stated the value of the applicant's improvements triggered the frontage improvements. Exhibits The February 14, 2107 Staff Report Exhibits 1-16 identified at part B of the Staff Report itself were admitted into the record during the hearing. In addition, the following exhibits were admitted during the hearing. Exhibit 17 Staff PowerPoint Exhibit 18 COR Maps Exhibit 19 Google Maps Exhibit 20 Landscape Narrative (December 13, 2106) FINDINGS OF FACT Procedural: I. Applicant. Puget Sound Energy. 2. Hearing. The Examiner held a hearing on the subject application on February 14, 2017 at 11 :00 am in the City of Renton Council Chambers. Substantive: 3. Project Description. Puget Sound Energy is requesting hearing examiner conditional use permit approval and site plan approval to perform improvements at the existing Talbot Hill Substation located at 2400 S. Puget Dr. The site is 50.4 acres. PSE is proposing to rebuild a portion of the Talbot CONDITIONAL USE 2 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Hill Substation in order to replace aging equipment. The existing 999sf oil storage building I will be demolished and replaced with a l ,440sf building. The existing 230kV substation equipment will be removed, including steel structures and foundations. No additional transmission lines are proposed with the rebuild of this project. A new storm drainage system is proposed within the fenced area. A detention pond will be installed south of the southerly substation fence. The detention pond will involve excavation of more than 500 cubic yards of soil. The substation footprint will remain unchanged. Access to the site is provided via an existing driveway extending from Puget Drive Southeast. Additional driveway improvements are proposed to allow larger vehicle access to the substation. The applicant proposes to construct the project in two phases. Phase one includes the civil portions of the project. This phase is proposed for April 2017 to October 2017. Phase two includes assembly of the electrical equipment which is proposed for April 2018 to October 2018. The project site contains moderate coalmine hazards, moderate landslide hazards, and sensitive slopes. The site is zoned Residential R-8 and the Comprehensive Plan designation is Residential Medium Density (RMD). The site is surrounded by single family uses in the R-8 zone on the north, east and south. To the west are single-family and multi-family dwellings in the R-8 and RMF zones. 4. Adequacy of Infrastructure/Public Services. The project will be served by adequate infrastructure and public services as follows: A. Water and Sewer Service. Neither water nor sewer service is proposed or required for the redevelopment project. B. Fire and Police. Police and Fire Prevention Staff indicate that sufficient resources exist to furnish services to the proposed development. C. Drainage. Runoff from the site sheet flows outward from the middle of the substation. There are existing drainage pipes from the northeast and southeast side of the substation which are tied to catch basins within the fence line. The rims of the catch basins are currently at an elevation higher than the surrounding ground, which prevents them from capturing stormwater. Grade differences between the substation slab and the surrounding ground surface along the north and northeast sides of the substation prevent stormwater from draining away from the substation, which tends to pond within the substation footprint. Runoff along the southern edge of the 1 The staff report refers to the structure as a control house, however, the applicant at hearing corrected the description. CONDITIONAL USE 3 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 substation flows into a culvert located beneath the access road which ultimately flows east towards Grant Avenue South. The applicant's Preliminary Drainage Plan and Technical Information Report (TIR) (Ex. 7) demonstrates compliance with the 2009 King County Surface Water Design Manual and the 20 IO City of Renton Amendments thereto. A new storm drainage system is proposed within the fenced area. A detention pond will be installed south of the southerly substation fence and will involve excavation of more than 500 cubic yards of soil. Drainage improvements include a new stormwater conveyance network inside the substation which would route flows to a 75,000-cubic foot stormwater detention pond located along the southeastern edge of the substation. The pond will discharge to a depression on the southern side of the existing access road, where flow would resume the existing drainage path towards Grand Avenue South. The applicant is exempt from water quality requirements. D. Parks/Open Space. City development standards do not require any set-asides or mitigation for parks and open space for the proposed use. E. Transportation. The site is bordered by Beacon Way South to the northeast. Beacon Way South is classified as a Residential Access Road and is located within the City of Seattle Cedar River Pipeline Easement. Access to the site is provided via an existing access driveway extending to Puget Drive Southeast. Puget Drive Southeast is classified as a Minor Arterial street. The existing right of way for Puget Drive Southeast is approximately I 00 feet wide and contains no frontage improvements. RMC 4-6-060 requires half street improvements including 0.5-foot curb, an eight-foot planting strip, an eight-foot sidewalk, street trees and storm drainage improvements. A condition of approval requires installation of half street improvements to code. Though the applicant indicated they will request a modification of the street frontage improvements pursuant to RMC 4-9-250.C.5.d, the applicant has not yet submitted such a request. No transportation impact fees are applicable to this project. F. Parking. Adequate parking exists on site to service the substation. No changes to the existing parking or driveway access are proposed. 5. Adverse Impacts. As conditioned, there are no significant adverse impacts associated with the project. Specific issues related to impacts are discussed below. A. Tree Retention. As conditioned, the proposal will satisfy tree retention and landscape screening requirements. The applicant submitted an arborist report and landscape narrative (Ex. 8 and 20) and a Stormwater Pond Tree Removal and Landscaping Plan (Ex. 4). A total of 116 significant trees are presently on site. The construction of the stormwater pond will remove a total of 69 trees. An additional 11 trees are proposed for removal to the west of the entrance driveway along CONDITIONAL USE 4 2 3 4 5 6 7 8 9 10 I I 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 the south side of the substation. Therefore, a total of 80 trees are proposed for removal. A total of 36 significant trees (31 %) are proposed for retention. The City's tree retention standards require a minimum of 30 percent tree retention. The proposal significantly complies with the City's tree retention requirements. The applicant has argued the 11 Douglas Firs located near the entrance drive pose a wind throw hazard to the substation and its operations. Though the applicant intends to retain shrubs and smaller trees in this area to serve as a landscape screen, the applicant did not provide an explanation as to why the trees cannot be pruned or trimmed rather than completely removed. A condition of approval will require the applicant to provide a revised arborists report detailing an explanation as to why no reasonable alternative to tree removal is possible. The condition will further require suggested locations and species of supplemental trees to replace the existing Douglas firs. B. Landscaping. As conditioned, no impacts from the proposed landscaping plan are anticipated. The applicant submitted a tree removal and landscaping plan (Ex. 4). The majority of the site will not be disturbed and existing native landscaping will continue to screen adjacent residential properties. The proposed new stormwater detention pond will be located along the southeaster edge of the substation. The City code requires a 15-foot landscape buffer around the storrnwater perimeter. The applicant has alternatively proposed landscape screening southwest of the stormwater pond, immediately south of the existing driveway, and to the west of the storrnwater pond outside the perimeter fence, rather than along the entire perimeter. The applicant plans to fill gaps in the existing natural vegetative screening between the substation and existing residences. The proposed site obscuring landscaping buffer will be 20 feet in width in these two locations and will contain a mix of trees and large shrubs. The existing vegetation provides screening when viewed from the southeast and southwest of the site. However, as noted above in FOF SA, the applicant proposes the removal of 11 trees south of the substation and to the west of the access drive. The applicant has not proposed additional plantings in this location. Removal of the trees in this location could reduce the effectiveness of the landscape screening. Therefore, a condition of approval will require the applicant to submit a revised tree replacement/visual barrier plan for this area. C. Geologically Hazardous Areas. Critical areas will not be adversely affected and the project will not result in impacts to health and safety for people utilizing the site or in surrounding areas. The applicant submitted a geotechnical report (Ex. 6). The project contains moderate coalmine and landslide hazards with sensitive slopes within 50 feet. The extent of disturbance for the proposal will be 5.89 acres. The net cut/fill will be 2,500-cubic yards with 11.500 cubic yards of cut and 9,000 cubic yards of fill. The geotechnical report concludes the proposal will not adversely affect the stability of the slopes in or around the site and coalmine hazards are minimal. In the absence of any contrary evidence, the examiner takes the geotechnical engineer's conclusions as verity. D. Structure Scale. The proposed new structure will have a maximum building height of 19' 4" with a 4: 12 pitched roof. The building will be obscured from view by the nearest residential area with native and planted landscaping. No adverse effects are anticipated for surrounding properties. CONDITIONAL USE 5 2 3 4 5 6 7 8 9 10 l l 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 E. Traffic. The Talbot Hill substation property is accessed via an ex1stmg access driveway extending from Puget Drive SE. The applicant is proposing improvements to the existing access driveway including repaving with asphalt, widening the approach apron, and a security gate. The project will not generate a significant number of vehicles trips either during construction or operation. No traffic impacts to the surrounding area are anticipated. F. Noise, Light and Glare. The reconstructed building will have minimal lighting to provide for safe egress. The lighting will be directed downward. No glare or light are expected to be visible from neighboring properties. The substation is over 460 feet from the nearest residential lot. No noise impacts to surrounding areas are anticipated. Conclusions of Law I. Authority. Large utilities are allowed in the R-8 district as a conditional use subject to Hearing Examiner review (RMC 4-2-060(0)). RMC 4-8-080(G) classifies conditional use applications as Type III permits when Hearing Examiner review is required. Site plan review is not required in the R-8 zone, except optionally when site plan review may be used as a means to propose modifications to development standards for developments otherwise exempt from site plan review (RMC 4-9- 200(8)(2)(b )). Pursuant to RMC 4-4-70(F)(8), site plan review is required for the proposal in order to deviate from storm drainage facility landscaping standards. In the absence of the conditional use permit application, no Hearing Examiner review would be required for the site plan and it would be classified as a Type II permit by RMC 4-8-080(G). Both of the aforementioned permits have been consolidated. RMC 4-8-080(C)(2) requires consolidated permits to each be processed under "the highest-number procedure". The conditional use has the highest numbered review procedures, so both permits must be processed as Type III applications. As Type III applications, RMC 4-8-0SO(G) grants the Examiner with the authority to hold a hearing and issue a final decision on them, subject to closed record appeal to the City Council. 2. Zoning/Comprehensive Plan Designations. The subject property is zoned R-8, a single family residential zone. The comprehensive plan land use designation is Residential Medium Density. 3.

Circulation: Providing desirable transitions and linkages between uses, streets, walkways and adjacent properties; iii. Loading and Storage Areas: Locating, designing and screening storage areas, utilities, rooftop equipment, loading areas, and refuse and recyclables to minimize views from surrounding properties; iv. Views: Recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features; v. Landscaping: Using landscaping to provide transitions between development and surrounding properties to reduce noise and glare, maintain privacy, and generally enhance the appearance of the project; and vi. Lighting: Designing and/or placing exterior lighting and glazing in order to avoid excessive brightness or glare to adjacent properties and streets. 13. The substation facility is necessarily concentrated on one portion of the site; however the scale and bulk of the building is compatible with the low rise residential structures that surround the site. As determined in Finding of Fact No. 5, no lighting or view impacts are anticipated and landscaping is effectively used to protect adjoining properties from noise and glare and to maintain privacy and enhance the appearance of the project. This criterion is satisfied. RMC 4-9-200(E)(3)(c): On-Site Impacts: Mitigation of impacts to the site, including: i. Structure Placement: Provisions for privacy and noise reduction by building placement, spacing and orientation; ii. Structure Scale: Consideration of the scale of proposed structures in relation to natural characteristics, views and vistas, site amenities, sunlight, prevailing winds, and pedestrian and vehicle needs; iii.

Land.,·caping: Use of landscaping to soften the appearance of parking areas, to provide shade and privacy where needed, to define and enhance open spaces, and generally to enhance the appearance of the project. Landscaping also includes the design and protection of planting areas so that they are less susceptible to damage from vehicles or pedestrian movements. 14. As determined in Finding of Fact No. 5, the site is large with 460 feet of native vegetation between the substation and the nearest residential area. As proposed and conditioned, native and planted landscaping has been well designed to provide for privacy and noise reduction. There is nothing in the record to reasonably suggest that the scale, spacing and orientation of the project could be modified to provide for more privacy and noise reduction without unreasonably interfering with the objectives of the facility. The scale of the facility will not create any adverse impacts as discussed and is compatible with vehicle and pedestrian circulation as determined in Finding of Fact No. 5. In addition, there is nothing in the record to reasonably suggest that the scale of the project is incompatible with sunlight, prevailing winds or natural characteristics. The comments by Staff on this criterion, at Finding No. 2l(f), are adopted by this reference and incorporated as if set forth in full. RMC 4-9-200(E)(3)(d): Access and Circulation: Safe and efficient access and circulation for all users, including: i.

Box 97034 Bellevue, WA 98009-9734 SUBJECT: Waiver of Requirements for Frontage Improvements along Puget Drive SE (Permit No. (17001111) Dear Ms. Kriner: The City of Renton has reviewed your request to waive the required half street improvement including 54-ft of paved roadway width (27-ft from centerline), 0.5-foot curb and gutter, 8-foot planting strip, 8-foot sidewalk, 2-foot clearance between sidewalk and right of way along the Puget Drive SE property frontage as noted in Municipal Code (RMC) 4-6-060(F). ANALYSIS: Frontage improvements are required by Renton Municipal Code for projects that exceed $50,000 value. However, RMC 4-6-250(() allows for a waiver of the requirements subject to the criteria below. Staff's analysis of the request follows each listed criteria. a. Required street improvements will alter an existing wetlands or stream, or have a negative impact on a shoreline's area. Staff Analysis: There are no wetlands or streams along Puget Drive SE. b. Existing steep topography would make required street improvements infeasible. Staff Analysis: There is a small portion of the right of way adjacent to Puget Drive SE that is a regulated steep slope however these regulated steep slopes are smo/1 in nature and would make the street improvements infeasible. c. Required street improvements would have a negative impact on other properties, such as restricting available access. Staff Analysis: The street improvements would have little to no negative impacts to other properties. 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov Ms. Kerry Kriner Page 2 of2 April 24, 2017 d. There are no similar improvements in the vicinity and there is little likelihood that the improvements will be needed or required in the next ten (10) years. Staff Analysis: Puget Drive SE is designated as a prapased bicycle corridor on the Renton Trails and Bicycle Master Plan. The Renton Trails and Bicycle Master Plan has lists Puget Drive SE between Panther Creek and 116'h Avenue SE/Beacon Way SE as a medium priority improvement project to construct the required street improvements along with bicycle lanes. Based on this, the street improvements will be needed in the next ten (10) years. e. In no case shall a waiver be granted unless it is shown that there will be no detrimental effect on the public health, safety or welfare if the improvements are not installed, and that the improvements are not needed for current or future development. Staff Analysis: See response to criterion "F. A bicycle corridor has been proposed along Puget Drive SE as part of the Renton Trails and Bicycle Master Plan and therefore it has been determined that the required street improvements are needed to maintain safety for bicyclists. DECISION: The requested waiver from frontage improvements (RMC 4-6-0GO(F) by the applicant is denied, as the request does not comply with the waiver criteria of RMC 4-6- 250((). This decision, to approve the waiver, is subject to a fourteen (14) day appeal period from the date of this letter per RMC 4-8-110. Any appeals of the administrative decision must be filed with the City Clerk, along with the required appeal fee, by 5:00 pm, May 9'h, 2017.

The applicant seeks to demolish an existing 999sfbuilding and replace it with a new l ,449sf building. The applicant will also remove substation equipment and create a new storm drainage system. The conditional use permit is approved with conditions. Testimony Angelea Weihs, Associate Planner, summarized the staff report and entered additional exhibits into the record (Ex. 17-19). She noted the City had received comment from Seattle PUD regarding access. In response to the examiner, Ms. Weihs stated the substation was in excess of 460 feet from the nearest residences and that the existing and proposed planting areas will serve as a buffer. Brianne Bannwarth, Development Engineering Manager, stated the project must meet the King County Stormwater Manual. In response to the examiner, Ms. Bannwarth stated all the potential impacts from the project with respect to construction are mitigated within the City's development codes. Ms. Bannwarth stated the City would be amenable to adding a condition of approval requiring the City to set up a call number for construction related concerns. CONDITIONAL USE 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Kerry Kriner, Planner for PSE, stated the staff report is incorrect in describing the building proposed for demolition as a control house. The building is actually an oil storage building. Ms. Kriner noted PSE had originally applied for a permit in March 2016 and was told the building was exempt from the !BC and therefore did not require a permit. In September, the City of Renton required an electrical permit and then reversed the need for a building permit. In response to the examiner, Jennifer Henning, Planning Director, stated the City had not originally known the building was taller than the maximum height for an accessory structure permitted within the zone. They had originally understood the building was smaller and not as tall. The electrical permit triggered the need for a building permit. The presence of a building permit triggered a conditional use permit because of the use within the zone. Ms. Kriner stated PSE objects to the City's $200,000 frontage improvement requirement and will be submitting a request for a waiver. No modifications or variances are currently at issue. Ms. Kriner stated the applicant had submitted a landscape narrative (Ex. 20). Ms. Henning stated the value of the applicant's improvements triggered the frontage improvements.

Exhibit 17 Staff PowerPoint Exhibit 18 COR Maps Exhibit 19 Google Maps Exhibit 20 Landscape Narrative (December 13, 2106) FINDINGS OF FACT Procedural: I. Applicant. Puget Sound Energy. 2. Hearing. The Examiner held a hearing on the subject application on February 14, 2017 at 11 :00 am in the City of Renton Council Chambers. Substantive: 3. Project Description. Puget Sound Energy is requesting hearing examiner conditional use permit approval and site plan approval to perform improvements at the existing Talbot Hill Substation located at 2400 S. Puget Dr. The site is 50.4 acres. PSE is proposing to rebuild a portion of the Talbot CONDITIONAL USE 2 2 3 4 5 6 7 8 9 10 11 12 13 14 [5 16 17 18 19 20 21 22 23 24 25 26 Hill Substation in order to replace aging equipment. The existing 999sf oil storage building I will be demolished and replaced with a l,440sfbuilding. The existing 230kV substation equipment will be removed, including steel structures and foundations. No additional transmission lines are proposed with the rebuild of this project. A new storm drainage system is proposed within the fenced area. A detention pond will be installed south of the southerly substation fence. The detention pond will involve excavation of more than 500 cubic yards of soil. The substation footprint will remain unchanged. Access to the site is provided via an existing driveway extending from Puget Drive Southeast. Additional driveway improvements are proposed to allow larger vehicle access to the substation. The applicant proposes to construct the project in two phases. Phase one includes the civil portions of the project. This phase is proposed for April 2017 to October 2017. Phase two includes assembly of the electrical equipment which is proposed for April 2018 to October 2018. The project site contains moderate coalmine hazards, moderate landslide hazards, and sensitive slopes. The site is zoned Residential R-8 and the Comprehensive Plan designation is Residential Medium Density (RMD). The site is surrounded by single family uses in the R-8 zone on the north, east and south. To the west are single-family and multi-family dwellings in the R-8 and RMF zones. 4. Adequacy of Infrastructure/Public Services. The project will be served by adequate infrastructure and public services as follows: A. Water and Sewer Service. Neither water nor sewer service is proposed or required for the redevelopment project. B. Fire and Police. Police and Fire Prevention Staff indicate that sufficient resources exist to furnish services to the proposed development. C. Drainage. Runoff from the site sheet flows outward from the middle of the substation. There are existing drainage pipes from the northeast and southeast side of the substation which are tied to catch basins within the fence line. The rims of the catch basins are currently at an elevation higher than the surrounding ground, which prevents them from capturing stormwater. Grade differences between the substation slab and the surrounding ground surface along the north and northeast sides of the substation prevent storrnwater from draining away from the substation, which tends to pond within the substation footprint. Runoff along the southern edge of the 1 The staff report refers to the structure as a control house~ however, the applicant at hearing corrected the description. CONDITIONAL USE 3 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 substation flows into a culvert located beneath the access road which ultimately flows east towards Grant A venue South. The applicant's Preliminary Drainage Plan and Technical Infonnation Report (TIR) (Ex. 7) demonstrates compliance with the 2009 King County Surface Water Design Manual and the 20 IO City of Renton Amendments thereto. A new storm drainage system is proposed within the fenced area. A detention pond will be installed south of the southerly substation fence and will involve excavation of more than 500 cubic yards of soil. Drainage improvements include a new storm water conveyance network inside the substation which would route flows to a 75,000-cubic foot stormwater detention pond located along the southeastern edge of the substation. The pond will discharge to a depression on the southern side of the existing access road, where flow would resume the existing drainage path towards Grand Avenue South. The applicant is exempt from water quality requirements. D. Parks/Open Space. City development standards do not require any set-asides or mitigation for parks and open space for the proposed use. E. Transportation. The site is bordered by Beacon Way South to the northeast. Beacon Way South is classified as a Residential Access Road and is located within the City of Seattle Cedar River Pipeline Easement. Access to the site is provided via an existing access driveway extending to Puget Drive Southeast. Puget Drive Southeast is classified as a Minor Arterial street. The existing right of way for Puget Drive Southeast is approximately 100 feet wide and contains no frontage improvements. RMC 4-6-060 requires half street improvements including 0.5-foot curb, an eight-foot planting strip, an eight-foot sidewalk, street trees and storm drainage improvements. A condition of approval requires installation of half street improvements to code. Though the applicant indicated they will request a modification of the street frontage improvements pursuant to RMC 4-9-250.C.5.d, the applicant has not yet submitted such a request. No transportation impact fees are applicable to this project. F. Parking. Adequate parking exists on site to service the substation. No changes to the existing parking or driveway access are proposed. 5. Adverse Impacts. As conditioned, there are no significant adverse impacts associated with the project. Specific issues related to impacts are discussed below. A. Tree Retention. As conditioned, the proposal will satisfy tree retention and landscape screening requirements. The applicant submitted an arborist report and landscape narrative (Ex. 8 and 20) and a Stormwater Pond Tree Removal and Landscaping Plan (Ex. 4). A total of 116 significant trees are presently on site. The construction of the stormwater pond will remove a total of 69 trees. An additional 11 trees are proposed for removal to the west of the entrance driveway along CONDITIONAL USE 4 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 the south side of the substation. Therefore, a total of 80 trees are proposed for removal. A total of 36 significant trees (31%) are proposed for retention. The City's tree retention standards require a minimum of 30 percent tree retention. The proposal significantly complies with the City's tree retention requirements. The applicant has argued the 11 Douglas Firs located near the entrance drive pose a wind throw hazard to the substation and its operations. Though the applicant intends to retain shrubs and smaller trees in this area to serve as a landscape screen, the applicant did not provide an explanation as to why the trees cannot be pruned or trimmed rather than completely removed. A condition of approval will require the applicant to provide a revised arborists report detailing an explanation as to why no reasonable alternative to tree removal is possible. The condition will further require suggested locations and species of supplemental trees to replace the existing Douglas firs. B. Landscaping. As conditioned, no impacts from the proposed landscaping plan are anticipated. The applicant submitted a tree removal and landscaping plan (Ex. 4). The majority of the site will not be disturbed and existing native landscaping will continue to screen adjacent residential properties. The proposed new stormwater detention pond will be located along the southeaster edge of the substation. The City code requires a 15-foot landscape buffer around the stormwater perimeter. The applicant has alternatively proposed landscape screening southwest of the stormwater pond, immediately south of the existing driveway, and to the west of the stormwater pond outside the perimeter fence, rather than along the entire perimeter. The applicant plans to fill gaps in the existing natural vegetative screening between the substation and existing residences. The proposed site obscuring landscaping buffer will be 20 feet in width in these two locations and will contain a mix of trees and large shrubs. The existing vegetation provides screening when viewed from the southeast and southwest of the site. However, as noted above in FOF 5A, the applicant proposes the removal of 11 trees south of the substation and to the west of the access drive. The applicant has not proposed additional plantings in this location. Removal of the trees in this location could reduce the effectiveness of the landscape screening. Therefore, a condition of approval will require the applicant to submit a revised tree replacement/visual barrier plan for this area. C. Geologically Hazardous Areas. Critical areas will not be adversely affected and the project will not result in impacts to health and safety for people utilizing the site or in surrounding areas. The applicant submitted a geotechnical report (Ex. 6). The project contains moderate coalmine and landslide hazards with sensitive slopes within 50 feet. The extent of disturbance for the proposal will be 5.89 acres. The net cut/fill will be 2,500-cubic yards with 11.500 cubic yards of cut and 9,000 cubic yards of fill. The geotechnical report concludes the proposal will not adversely affect the stability of the slopes in or around the site and coalmine hazards are minimal. In the absence of any contrary evidence, the examiner takes the geotechnical engineer's conclusions as verity. D. Structure Scale. The proposed new structure will have a maximum building height of 19' 4" with a 4: 12 pitched roof. The building will be obscured from view by the nearest residential area with native and planted landscaping. No adverse effects are anticipated for surrounding properties. CONDITIONAL USE 5 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 E. Traffic. The Talbot Hill substation property is accessed via an ex1stmg access driveway extending from Puget Drive SE. The applicant is proposing improvements to the existing access driveway including repaving with asphalt, widening the approach apron, and a security gate. The project will not generate a significant number of vehicles trips either during construction or operation. No traffic impacts to the surrounding area are anticipated. F. Noise, Light and Glare. The reconstructed building will have minimal lighting to provide for safe egress. The lighting will be directed downward. No glare or light are expected to be visible from neighboring properties. The substation is over 460 feet from the nearest residential lot. No noise impacts to surrounding areas are anticipated. Conclusions of Law I. Authority. Large utilities are allowed in the R-8 district as a conditional use subject to Hearing Examiner review (RMC 4-2-060(0)). RMC 4-8-0SO(G) classifies conditional use applications as Type Ill permits when Hearing Examiner review is required. Site plan review is not required in the R-8 zone, except optionally when site plan review may be used as a means to propose modifications to development standards for developments otherwise exempt from site plan review (RMC 4-9- 200(B)(2)(b)). Pursuant to RMC 4-4-70(F)(8), site plan review is required for the proposal in order to deviate from storm drainage facility landscaping standards. In the absence of the conditional use permit application, no Hearing Examiner review would be required for the site plan and it would be classified as a Type II permit by RMC 4-8-080(0). Both of the aforementioned permits have been consolidated. RMC 4-8-080(C)(2) requires consolidated permits to each be processed under "the highest-number procedure". The conditional use has the highest numbered review procedures, so both permits must be processed as Type Ill applications. As Type Ill applications, RMC 4-8-0SO(G) grants the Examiner with the authority to hold a hearing and issue a final decision on them, subject to closed record appeal to the City Council. 2. Zoning/Comprehensive Plan Designations. The subject property is zoned R-8, a single family residential zone. The comprehensive plan land use designation is Residential Medium Density. 3. Review Criteria. Conditional use criteria are governed by RMC 4-9-030(C). Site plan review criteria are governed by RMC 4-9-200(E).

As stated in FOF SF, no impacts from noise, light or glare are anticipated. This criterion is satisfied. RMC 4-9-030(C)(8): Landscaping: Landscaping shall be provided in all areas not occupied by buildings, paving, or critical areas. Additional landscaping may be required to buffer adjacent properties from potentially adverse effects of the proposed use. 11. As conditioned, the landscape complies with the City's landscape regulations. As described in FOF 5(8), landscaping will provide a vegetative screening between the substation and adjacent residential areas. The reconstructed building and stormwater pond will be fully screened. As conditioned, this criterion is met. Site Plan RMC 4-9-200(E)(3): Criteria: The Administrator or designee must find a proposed project to be in compliance with the following: a. Compliance and Consistency: Co,iformance with plans, policies, regulations and approvals, including: i. Comprehensive Plan: The Comprehensive Plan, its elements, goals, objectives, and policies, especially those of the applicable land use designation; the Community Design Element; and any applicable adopted Neighborhood Plan; ii. Applicable land use regulations; iii. Relevant Planned Action Ordinance and Development Agreements; and iv. Design Regulations: Intent and guidelines of the design regulations located in RMC 4-3-100. 12. As discussed in Conclusion of Law No. 4, as conditioned, the proposal is consistent with the City's comprehensive plan, as well as development and design regulations. The proposal does not qualify as a Planned Action Ordinance, as outlined at Finding No. 2 l(d) of the Staff Report. The Staff CONDITIONAL USE 8 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Report Findings of Fact and Conclusions of Law are adopted and incorporated by reference as if set forth in full. RMC 4-9-200(E)(3)(b): Off-Site Impacts: Mitigation of impacts to surrounding properties and use.,·, including: i. Structures: Restricting overscale structures and overconcentration of development on a particular portion of the site; iL Circulation: Providing desirable transitions and linkages between uses, streets, walkways and adjacent properties; iiL Loading and Storage Areas: Locating, designing and screening storage areas, utilities, rooftop equipment, loading areas, and refuse and recyclables to minimize views from surrounding properties; iv. Views: Recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features; v. Landscaping: Using landscaping to provide transitions between development and surrounding properties to reduce noise and glare, maintain privacy, and generally enhance the appearance of the project; and vi. Lighting: Designing and/or placing exterior lighting and glazing iri order to avoid excessive brightness or glare to adjacent properties and streets. 13. The substation facility is necessarily concentrated on one portion of the site; however the scale and bulk of the building is compatible with the low rise residential structures that surround the site. As determined in Finding of Fact No. 5, no lighting or view impacts are anticipated and landscaping is effectively used to protect adjoining properties from noise and glare and to maintain privacy and enhance the appearance of the project. This criterion is satisfied. RMC 4-9-200(E)(3)(c): On-Site Impacts: Mitigation of impacts to the site, including: i. Structure Placement: Provisions for privacy and noise reduction by building placement, spacing and orientation; ii. Structure Scale: Consideration of the scale of proposed structures in relation to natural characteristics, views and vistas, site amenities, sunlight, prevailing winds, and pedestrian and vehicle needs; iii. Natural Features: Protection of the natural landscape by retaining existing vegetation and soils, using topography to reduce undue cutting and filling, and limiting impervious surfaces; and CONDITIONAL USE 9 2 3 4 5 6 7 8 9 IO 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 iv. Landscaping: Use of landscaping to soften the appearance of parking areas, to provide shade and privacy where needed, to define and enhance open spaces, and generally to enhance the appearance of the project. Landscaping also includes the design and protection of planting areas so that they are less susceptible to damage from vehicles or pedestrian movements. 14. As determined in Finding of Fact No. 5, the site is large with 460 feet of native vegetation between the substation and the nearest residential area. As proposed and conditioned, native and planted landscaping has been well designed to provide for privacy and noise reduction. There is nothing in the record to reasonably suggest that the scale, spacing and orientation of the project could be modified to provide for more privacy and noise reduction without unreasonably interfering with the objectives of the facility. The scale of the facility will not create any adverse impacts as discussed and is compatible with vehicle and pedestrian circulation as determined in Finding of Fact No. 5. In addition, there is nothing in the record to reasonably suggest that the scale of the project is incompatible with sunlight, prevailing winds or natural characteristics. The comments by Staff on this criterion, at Finding No. 21(!), are adopted by this reference and incorporated as if set forth in full. RMC 4-9-200(E)(3)(d): Access and Circulation: Safe and efficient access and circulation for all users, including: i. Location and Consolidation: Providing access points on side streets or frontage streets rather than directly onto arterial streets and consolidation of ingress and egress points on the site and, when feasible, with adjacent properties; ii. Internal Circulation: Promoting safety and efficiency of the internal circulation system, including lhe location, design and dimensions of vehicular and pedestrian access poinls, drives, parking, lurnarounds, walkways, bikeways, and emergency access ways; iii. Loading and Delivery: Separaling loading and delivery areas from parking and pedestrian areas; iv. Transit and Bicycles: Providing lransit, carpools and bicycle facilities and access; and v.

Date: December 13, 2016 Project No.: 31983.h EXHIBIT 8 Entire Document Available Upon Request The arborist report is required to accompany a Renton Site Plan Review-submittal. It is developed to convey specific information regarding the trees proposed for removal, tree protection for trees to be retained and supplemental tree planting suggestions. I am coordinating the integration of tree removal, tree retention and tree protection into the landscape plans of the stormwater pond. Assessment Methods The inventory of trees was performed on October 13, 2016. The inventory is tabulated in the tree table which includes an assignment of tree number, identification of tree species by common and botanical names, diameter at breast height (D BH) measurement, a condition assessment using five categories (Excellent, Good, Fair, Poor and Dead) based on visual tree inspection of each tree, comments specific to each trees condition and the proposal to either remove or retain the tree. In the case of trees with multiple stems, typically beaked hazelnut trees in this case, I've noted the approximate number of stems and the stems average size. Site description The site address is 3004 Beacon Way South. The location of the subject trees is along the south side and southeast comer of the PSE Talbot Hill Substation. The land surface is undulating with vegetation typical of upland plant species. See figure 1. The majority of the trees are in good shape with the exception of the willow and alder; they have been damaged by recent branch failures during the spring windstorms.

The current adopted building code is 2015 International Building Code. Recommendations of the geotechnical report must be followed as a condition of building permits. Geotechnical reoort should be uodated to 2015 IBC desian oarameters. Engineering Review Comments Contact: Ann Fowler I 425-430-7382 I afowler@rentonwa.gov Recommendations: I have reviewed the application for the Talbot Hill Substation at 2400 S Puget Drive (APN('s} 202305 9003, 9066, 9064) and have the following comments: EXISTING CONDITIONS The total site is approximately 50.4 acres acres in size and is irregular in shape. The site includes an existing substation wiU, access gravel driveways. The substation covers approximately 7. 75 acres of the total site area. Water No water service is proposed or required for the redevelopment project. EXHIBIT 10 Sewer No sewer service is proposed or required for the redevelopment project. Storm Runoff from the site sheet flows outward from the middle of the substation. There are existing drainage pipes on the northeast and southeast side of the substation which are tied to catch basins within the fence line. The rims of the catch basins are currently at an elevation higher than the surrounding ground, which prevents them from capturing stormwater. Grade differences between the substation slab and the surrounding ground surface along the north and northeast sides of the substation prevents stormwater from draining away from the substation and tends to pond within the substation footprint. Runoff along the southern edge of the substation flows into a culvert located beneath the access road which ultimately flows east towards Grant Avenue South. Streets The site is bordered by Beacon Way South to the northeast. Beacon Way South is classified as a Residential Access Road and is located within the City of Seattle Cedar River Pipeline Easement. The site is bordered by Puget Drive Southeast to the south. Puget Drive Southeast is classified as a Minor Arterial Street. Existing right of way in Puget Drive Southeast is approximately 100 feet as measured using the King County Assessor's Map. There are no existing frontage improvements along Puget Drive Southeast. CODE REQUIREMENTS SURFACE WATER 1. A geotechnical report, dated December 5, 2016, completed by GeoEngineers, Inc. for the site has been provided. The project site contains moderate coalmine hazards, moderate landslide hazards and sensitive slopes (within 50 feet). Erosion control measures will need to be in place prior to starting grading activities on the site. The report discusses the soil and groundwater characteristics of the site including infiltration potential and provides recommendations for project design and construction. The report discounts the use of infiltration for the site due to the depth of the outwash soils compared to the existing surface elevations present on the site. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated November 16, 2016, was submitted by HDR Engineering, Inc. with the Land Use Application. Based on the City of Renton's flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the Lower Cedar River and Black River Drainage Basin. The development is subject to Full Drainage Review in accordance with the 2009 King County Surtace Water Design Manual (KCSWDM) and the 2010 City of Renton Amendments to the KCSWOM.

Engineering Review Comments Contact: Ann Fowler 1425-430-73821 afowler@rentonwa.gov Recommendations: I have reviewed the application for the Talbot Hill Substation at 2400 S Puget Drive (APN('s) 202305 9003, 9066, 9064} and have the following comments: EXISTING CONDITIONS The total site is approximately 50.4 acres acres in size and is irregular in shape. The site Includes an existing substation with access gravel driveways. The substation covers approximately 7.75 acres of the total site area. Water No water service is proposed or required for the redevelopment project. EXHIBIT 10 Sewer No sewer service is proposed or required for the redevelopment project. Storm Runoff from the site sheet flows outward from the middle of the substation. There are existing drainage pipes on the northeast and southeast side of the substation which are tied to catch basins within the fence line. The rims of the catch basins are currently at an elevation higher than the surrounding ground, which prevents them from capturing stormwater. Grade differences between the substation slab and the surrounding ground surface along the north and northeast sides of the substation prevents stonnwater from draining away from the substation and tends to pond within the substation footprint Runoff along the southern edge of the substation flows into a culvert located beneath the access road which ultimately flows east towards Grant Avenue South. Streets The site is bordered by Beacon Way South to the northeast. Beacon Way South is classified as a Residential Access Road and Is located within the City of Seattle Cedar River Pipeline Easement. The site is bordered by Puget Drive Southeast to the south. Puget Drive Southeast is dassified as a Minor Arterial Street. Existing right of way in Puget Drive Southeast is approximately 100 feet as measured using the King County Assessor's Map. There are no existing frontage improvements along Puget Drive Southeast. CODE REQUIREMENTS SURFACE WATER 1. A geotechnical report, dated December 5, 2016, completed by GeoEngineers, Inc. for the site has been provided. The project site contains moderate coalmine hazards, moderate landslide hazards and sensitive slopes (within 50 feet). Erosion control measures will need to be in place prior lo starting grading activities on the site. The report discusses the soil and groundwater characteristics of the site induding infiltration potential and provides recommendations for project design and construction. The report discounts the use of infiltration for the site due to the depth of the ovtwash soils compared to the existing surface elevations present on the site. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated November 16, 2016, was submitted by HDR Engineering, Inc. with the Land Use Application. Based on the City of Renton's flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the Lower Cedar River and Black River Drainage Basin.

The project site totals 50.4 acres and is zoned Residential-8 (R-8). PSE is proposing to rebuild a portion of the Talbot Hill Substation in order to replace aging equipment and provide more reliability for the transmission lines connected to the substation. The existing control house will be demolished and a new control house will be constructed in its place. The proposed new control house exceeds the maximum height for accessory structures within the R-8 zone, and therefore requires approval of a Hearing Examiner Conditional Use Permit. The existing 230kV substatio~ equipment inside the fence is proposed to be removed, including steel structures and foundations. The new equipment will be reconfigured to create a more efficient and more reliable substation and allow for flexible functioning of the system. The proposal includes some transmission line work outside the substation fence; however, no additional transmission lines are proposed with the rebuild of this project. A new storm drainage system will be constructed within the fenced area and a detention pond will be installed south of the southerly substation fence. The detention pond will involve an excavation of more than 500 cubic yards, which will trigger SEPA Review. The substation footprint will remain unchanged. The storm improvements will require the removal of 63 trees. Additional driveway improvements are proposed to allow larger vehicle access to the substation. The project site contains moderate coalmine hazards, moderate landslide hazards, and sensitive slopes (within SO feet). The applicant has submitted an Arborist Report and Geotechnical Engineering Study with the application.

In order to accomplish this total disturbed area will equal approximately 227,370 square feet. The cut will be about 11,500 cubic yards and fill of about 9,000 cubic yards. After construction the area of impervious surface will equal about 78,131 square feet and the pervious surface: 149,238 square feet. Location: The site is located atl2400 S Puget Drive on parcels 2023059003, 2023059066iand 2023059064. Land Use Permits Required: Site Plan Review with SEPA.

We are proposing to remove 63 significant trees and retain 34. See attached arborist report for detailed information. • Job shack or trailer location: Unknown at this time; to be determined by contractor. • Proposed modification and stream or wetlands: There are no known wetlands or streams in the project vicinity. The substation improvements, with the exception of the stormwater pond, will remain within the existing fenced area. • Existing Access: There are no proposed off-site improvements, no land dedicated to the city. o Regarding Note 16 in Title Report: PSE's legal and physical access to all three parcels noted above is off the north side of Puget Drive SE at 2023059064. EXHIBIT 16 Conditional Use Permit Justification (Control House'): • Consistency with Plans and Regulations: The proposed use shall be compatible with the general purpose, goals, objectives and standards of the comprehensive plan, the zoning ordinance and any other plans, programs, maps or ordinances of the City of Renton. Response: The proposed use is not changing. The proposal includes replacing an existing control house within the Talbot Hill substation with a new control house. The use is compatible with the general purpose, goals, objectives and standards of the comprehensive plan, the zoning ordinance and any other plans, programs, maps or ordinances of the City of Renton. The Utilities Element of the Comprehensive Plan states: The Utilities Element guides future utility service within Renton's planning area and ensures that adequate utility services will be available to support existing and future development in the City. The goals and policies included in the Utilities Element are designed to promote efficient, cost effective utility service while meeting community needs and protecting both existing neighborhoods and the nature environment. The proposal complies with the following Comprehensive Plan goals and policies: Policy U-7: Non-City utility systems should be constructed in a manner that minimizes negative impacts to existing development and should not interfere with operation of City utilities. City development regulations should otherwise not limpair the ability of utility providers to adequately serve customers. Goal U-0: Promote the availability of safe, adequate, and efficient electrical service within the City and its planning area, consistent with the regulatory obligation of the utility to serve customers. Policy U-72: Coordinate with local and regional utility providers to ensure the siting and location of transmission and distribution facilities is accomplished in a manner that minimizes adverse impacts to the environment and adjacent land uses. Policy U-73: Encourage electricity purveyors to make facility improvements and additions within existing utility corridors whenever possible. The proposed control house structure will replace an existing control house within the Talbot Hill substation fence. The proposal will have little to no impact on adjacent residential, as the existing use of the site will not change. The control house will replace an existing structure and be located adjacent to the existing structure. There are existing transmission corridors between the substation and neighboring residential properties. The City of Renton has determined that a control house is an accessory building to the substation use. The maximum wall plate in the R-8 zone for an accessory building is 12 feet. The proposed control house wall plate is 11 feet. However, since the overall height exceeds more than 6 feet above the wall plate (RMC 4-2-llOD.18 Vertical Projections from Wall Plates), the City determined that Conditional Use Permit approval is required for the new control house structure. The proposed control house will comply with all other applicable dimensional standards of the R-8 zone. As evidenced through this analysis, the proposed control house is consistent with the Conditional Use Permit decision criteria outlined in RMC 4-9-030.D. 1 A substation control house is a shelter containing equipment necessary to monitor and control the operation of the substation. At smaller or older substations this usually takes the form of a weather-protective cabinet, where maintenance and operation of control equipment can be performed by technicians standing outside, and reaching into, the cabinet ("house"). At larger or newer substations, which require more complex control and control-related communications equipment, this will necessarily take the form of a larger weather-protective shelter, which technicians may enter into to service and operate the equipment. This shelter is solely for the purpose of containing the control equipment; compared to other work or storage spaces, a control house is entered only while actively servicing the equipment it contains. • Appropriate Location: The proposed location shall not result in the detrimental overconcentration of a particular use within the City or within the immediate area of the proposed use. The proposed location shall be suited for the proposed use. Response: The proposed location of the control house will not result in detrimental overconcentration of a particular use within the City or within the immediate area. The proposed control house will replace an existing control house within the substation fence. The increased building square footage is minor compared to the scale of the substation footprint. The new control house will be located adjacent to the existing structure used for a control house and will not be substantially larger in size. • Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. Response: The proposed control house will not result in substantial or undue adverse effects on adjacent property. The proposed control house will replace an existing control house adjacent to the current structure location within the existing substation fence. The substation is located within a 50 acre site that contains several transmission lines. The substation is located over 460 feet from the nearest residential lot, resulting in no substantial impact to neighboring properties. • Compatil:lility: The proposed use shall be compatible with the scale and character of the neighborhood. Response: The proposed use is compatible with the scale and character of the neighborhood. Talbot Substation is an existing station that was constructed in the early 1960's. There is an existing control house structure within the substation fence that's use will be replaced with the new structure. The substation is over 460 feet from the nearest residential lot and completely surrounded by transmission corridors. The proposed control house is part of the same use that has been on the site for more than 50 years. • Parking: Adequate parking is, or will be made, available.

LUA16-000922 Jeff McMeekin, Puget Sound Energy Talbot Hill Substation Improvements PROJECT DESCRIPTION: PSE is requesting Hearing Examiner Conditional Use Permit, Environmental (SEPA) Review, and Site Plan Review for proposed Talbot Hill Substation improvements located at 2400 S Puget Dr. (parcel numbers 2023059003 and 2023059066). The project site totals 50.4 acres and is zoned Residential-8 (R-8). PSE is proposing to rebuild a portion of the Talbot Hill Substation in order to replace aging equipment and provide more reliability for the transmission lines connected to the substation. The existing control house will be demolished and a new control house will be constructed in its place. The proposed new control house exceeds the maximum height for accessory structures within the R-8 zone, and therefore requires approval of a Hearing Examiner Conditional Use Permit. The existing 230kV substation equipment inside the fence is proposed to be removed, including steel structures and foundations. The new equipment will be reconfigured to create a more efficient and more reliable substation and allow for flexible functioning of the system. The proposal includes some transmission line work outside the substation fence; however, no additional transmission lines are proposed with the rebuild of this project. A new storm drainage system will be constructed within the fenced area and a dete'ntion pond will be installed south of the southerly substation fence. The detention pond will involve an excavation of more than 500 cubic yards, which will trigger SEPA Review. The substation footprint will remain unchanged. The storm improvements will require the removal of 63 trees. Additional driveway improvements are proposed to allow larger vehicle access to the substation. The project site contains moderate coalmine hazards, moderate landslide hazards, and sensitive slopes (within 50 feet). The applicant has submitted an Arborist Report and Geotechnical Engineering Study with the application. PROJECT LOCATION: LEAD AGENCY: 2400 S Puget Dr. City of Renton Environmental Review Committee Department of Community & Economic Development The City of Renton Environmental Review Committee has determined that it does not have a probable significant adverse impact on the environment.

The project site totals 50.4 acres and is zoned Residential-8 (R-8). PSE is proposing to rebuild a portion of the Talbot Hill Substation in order to replace aging equipment and provide more reliability for the transmission lines connected to the substation. The existing control house will be demolished and a new control house will be constructed in its place. The proposed new control house exceeds the maximum height for accessory structures within the R-8 zone, and therefore requires approval of a Hearing Examiner Conditional Use Permit. The existing 230kV substation equipment inside the fence is proposed to be removed, including steel structures and foundations. The new equipment will be reconfigured to create a more efficient and more reliable substation and allow for flexible functioning of the system . The proposal includes some transmission line work outside the substation fence; however, no additional transmission lines are proposed with the rebuild of this project. A new storm drainage system will be constructed within the fenced area and a detention pond will be installed south of the southerly substation fence. The detention pond will involve an excavation of more than 500 cubic yards, which will trigger SEPA Review. The substation footprint will remain unchanged. The storm improvements will require the removal of 63 trees. Additional driveway improvements are proposed to allow larger vehicle access to the substation . The project site contains moderate coal mine hazards, moderate landslide hazards, and sensitive slopes (within SO feet). The applicant has submitted an Arborist Report and Geotechnical Engineering Study with the application.

Engineering Review Comments Contact: Ann Fowler I 425-430-7382 I afowler@rentonwa.gov Recommendations: I have reviewed the application for the Talbot Hill Substation at 2400 S Puget Drive (APN('s) 202305 9003, 9066, 9064) and have the following comments: EXISTING CONDITIONS The total site is approximately 50.4 acres acres in size and is irregular in shape. The site includes an existing substation with access gravel driveways. The substation covers approximately 7.75 acres of the total site area. Water No water service is proposed or required for the redevelopment project. Sewer No sewer service is proposed or required for the redevelopment project. Stonn Runoff from the site sheet flows outward from the middle of the substation. There are existing drainage pipes on the northeast and southeast side of the substation which are tied to catch basins within the fence line. The rims of the catch basins are currently at an elevation higher than the surrounding ground, which prevents them from capturing stonnwater. Grade differences between the substation slab and the surrounding ground surface along the north and northeast sides of the substation prevents stormwater from draining away from the substation and tends to pond within the substation footprint. Runoff along the southern edge of the substation flows into a culvert located beneath the access road which ultimately flows east towards Grant Avenue South. Streets The site is bordered by Beacon Way South to the northeast. Beacon Way South is classified as a Residential Access Road and is located within the City of Seattle Cedar River Pipeline Easement. The site is bordered by Puget Drive Southeast to the south. Puget Drive Southeast is classified as a Minor Arterial Street. Existing right of way in Puget Drive Southeast is approximately 100 feet as measured using the King County Assessor's Map. There are no existing frontage improvements along Puget Drive Southeast. CODE REQUIREMENTS SURFACE WATER 1. A geotechnical report, dated December 5, 2016, completed by GeoEngineers, Inc. for the site has been provided. The project site contains moderate coalmine hazards, moderate landslide hazards and sensitive slopes (within 50 feet). Erosion control measures will need to be in place prior to starting grading activities on the site. The report discusses the soil and groundwater characteristics of the site including infiltration potential and provides recommendations for project design and construction. The report discounts the use of infiltration for the site due to the depth of the outwash soils compared to the existing surface elevations present on the site. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical lnfonnation Report (TIA), dated November 16, 2016, was submitted by HDR Engineering, Inc. with the Land Use Application. Based on the City of Renton's flow control map, the site falls within the Flow Control Duration Standard area matching Forested Site Conditions and is within the Lower Cedar River and Black River Drainage Basin. The development is subject to Full Drainage Review in accordance with the 2009 King County Surface Water Design Manual (KCSWDM) and the 2010 City of Renton Amendments to the KCSWDM. All core requirements and the six special requirements are discussed in the Technical Information Report. The following stormwater improvements are required and shall be discussed within the TIA: a. The applicant submitted a complete Condition Use Pennit Application on December 6, 2016 and is therefore vested to the 2009 KCSWDM and the 201 o City of Renton Amendments to the KCSWDM for a period of 180 days from the application date. The vesting period will expire on June 4, 2017 in accordance with AMC 4 1 045E.2.b. A complete Construction Permit Application must be received prior to the expiration date of the vesting period. Otherwise, the applicant will be required to comply with the stormwater manual that is in effect at the time of construction pennit application. b. Appropriate flow control BMPs will be required to help mitigate the new runoff created by this development since the new plus replaced impervious area is over 2,000 square feet. A preliminary drainage plan, including the application of flow control BMPs, shall be included with the land use application, as applicable to the project. c. As noted in the report, the applicant is exempt from water quality since the new plus replaced pollution generating impervious surface (PGIS) area is less than 5,000 square feet. Any changes to the redevelopment project which results in greater than 5,000 square feet of PGIS area, as defined by the 2009 KCSWDM, may trigger water quality facilities to be provided. 3. The applicant has proposed installation of a new stonnwater conveyance system inside the substation which will route flows to a new --------Renton 0 PLAN -Planning Review -Land Use Engineering Review Comments Contact: Ann Fowler I 425-430-7382 I afowler@rentonwa.gov detention pond to be located at the sound end of the substation between the substation and the access road in order to mitigate the added impervious surface area of the redevelopment project. 4. All work proposed outside of the applicant's property will require a permanent drainage easement to be provided to the City and a temporary construction easement prior to any permits being issued. 5. A Construction Stormwater General Permit from Department of Ecology is required since grading and clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan (SWPPP) is required for this site. 6. Surface water system development fee is $0.641 per square foot of new impervious surface, but not less than $1,608.00. This is payable prior to issuance of the construction permit. TRANSPORTATION 1. Per City code 4 6 060, required half street frontage improvements shall include 54 ft of paved roadway width (27 ft from centerline), installation of a 0.5 foot curb, an 8 foot planting strip, an 8 foot sidewalk, street trees and storm drainage improvements. No right of way dedication is required. 2. Refer to City code 4 4 080 regarding driveway regulations. Driveways shall be designed in accordance with City standard plans 104.1 and 104.2. a. The maximum width of any driveway shall not exceed 30 feet at the right of way line. b. Driveways shall be located a minimum of 5 feet from property lines. c. Maximum driveway slope is 8%. 3. Paving and trench restoration shall comply with the City's Trench Restoration and Overlay Requirements for any work within the City right of way. GENERAL COMMENTS 1.

"Chip" Vincent, Administrator SUBJECT: Talbot Hill Substation Improvements comment response letter LUA16·000922, ECF, SA-H, Dear Bob Gambill: Thank you for your comments related to the Talbot Hill Substation Improvements as part of the public comment period. Your email, dated December 28, 2016, specified concerns about the Seattle Public Utilities' Cedar River Water Transmission Pipelines Right of Way, which is adjacent to the Talbot Hill Substation Project Area. You specifically mentioned a concern about PSE/substation- related traffic using the Seattle Public Utilities Right of Way for vehicle access. The Talbot Hill substation property is accessed via an existing access driveway extending from S Puget Drive (See the attached site plan and proposed access improvements). As part of the project, the applicant is proposing improvements to the existing access driveway that includes repaving with asphalt, widening of the approach apron, and a security gate. The access driveway will remain in its current location. Thank you for providing comments. If you would like to review the project file, the submitted documents are available on the 61h Floor of City Hall. You have been added as a Party of Record to receive notifications as the project moves through the application process.

The following comments on development and permitting Issues ;,re based on the pre-application submittals made to the City of Renton by the applicant and the codes In effect on the date of review. The applicant Is cautioned that information contained In this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, Development Services Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant.

Project Proposal: The subject property (Tax Parcel nos. 2023059066 and 2023059003) Is located at 2400 S Puget Dr. The project site totals 50.4 acres and Is zoned Resldential-8 (R-8). PSE is proposing to rebuild a portion of their Talbot Hill Substation located at this locatlon, to replace aging equipment. PSE Is proposing to remove the existing 230kV substation equipment Inside the fence, Including steel structures and foundations, and replace with new equipment. The proposed work would include some transmission line work outside the substation fence; however, no additional transmission lines will be added with the rebuild of this project. A new storm drainage system will be constructed within the fenced area and a detention pond will be installed south of the southerly substation fence. The substation footprint will remain unchanged. The storm Improvements would require the removal of about 12 mature trees. Additional driveway improvements/widening are proposed to allow larger vehicle access to the substation. The project site contains moderate coalmlne hazards, moderate landslide hazards, and sensitive slopes (within 50 feet). Zoning Info: The subject property Is zoned Residential -8 (R-8). "Utilities, large" are permitted within the R-8 Zone with approval of a Hearing Examiner Conditional Use Permit on the condition that "aboveground public utility facilities, such as water towers, reservoirs, water H:\CED\Plannlns\Current Plannlng\PREAPPS\2016 Preapps\PRE16-000437.Angelea\PRE16-000437 PSE Substation Planning Comments.docx PSE Talbot HIii Substation Page 2of3 July 7, 2016 • • • • treatment facilities, and pump stations shall be treated with public art, subject to approval by the Arts Commission." Staff could find no conditional use permit associated with this property; therefore, the use would be considered a legal, nonconforming use. A condition use permit would need to be obtained In order to enlarge or expand the use so as to occupy additional land area (or increase capacity) on the same or any other lot or parcel. Fencing: All flow control and water quality treatment ponds and similar facilities, as determined by City Development Services, shall be fenced with a six-foot (6') tall chain link fence and access gate. Fencing is required Immediately outside each new stormwater flow control and/or water quality treatment pond and other similar facilities, as determined by City Development Services. For stormwater ponds, the fence shall be placed at the top of the berm with the maintenance access road on the inside of the fence; or five feet (S') minimum from top of berm If there Is no maintenance access road to allow access for proper maintenance of the facility. The chain link fence shall be coated with black or green bonded vinyl and Installed as determined by the City between the facility and the required landscaping. Unless otherwise determined by the City, the fence gate must be posted with a twelve inch {12"1 by eighteen inch (18") "No Trespassing" sign. Cedar or other fencing materials may be Installed only If the stormwater facility is a privately maintained facility that is owned and operated by the owner(s) of the tract. Landscaping: Except for critical areas, all portions of the development area not covered by structures, ~equired parking, access, circulation or service areas, must be landscaped with native, drought-resistant vegetative cover. The perimeter of all new flow control and/or water quality treatment stormwater facilities shall be landscaped in accordance with the provisions of RMC 4-4-070 and the Surface Water Design Manual. A landscaping strip with a minimum fifteen feet {15') of width shall be located on the outside of the fence, unless otherwise determined through the site plan review or subdivision review process. Plantings shall be consistent with the Surface Water Design Manual and RMC 4-4-070. Additionally, trees must be spaced as determined by the Department of Community and Economic Development. Trees and shrubs are prohibited on any berm serving a drainage-related function, within the fenced area of the drainage facility, and within ten feet {10') of any manmade drainage structure (e.g., catch basins, ditches, pipes, vaults, etc.); however, groundcover is required and subject to City review/approval. In the event of a conflict between this Section and the Surface Water Design Manual, the landscaping provisions shall prevail. Please refer to landscape regulations (RMC 4-4· 070) for further general and specific landscape requirements. A conceptual landscape plan shall be submitted with permit application. Significant Tree Retention: Utility Uses shall be exempt from the protected tree retention requirements of RMC 4-4·130 if the applicant can Justify the exemption in writing to the Administrator's satisfaction. Critical Areas: Moderate coalmine hazards, moderate landslide hazards, and sensitive slopes are mapped within SO feet of the project site. Whenever a proposed development requires a development permit and a geologic hazard, Including sensitive slopes, Is present on the site of the proposed development or on abutting or adjacent sites within fifty feet {SO') of the subject site, geotechnlcal studies by licensed professionals, such as a geotechnical engineer and/or engineering geologist, shall be required. The geotechnlcal report would need to demonstrate that the proposal would not Increase the threat of the geological hazard to adjacent or abutting properties beyond pre-development conditions; the proposal will not adversely impact other H :\CEO\Planning\Current Plannlng\PREAPPS\2016 Preapps\PRE16-000437.Angelea\PRE16-000437 PSE Substation Planning Camments.docx a PSE Talbot HIii Substation I Page3 of3 July 7, 2016 critical areas; and the development can be safely accommodated on the site.

H:\CED\Plannlng\Current Planning\PREAPPS\2016 Preapps\PRE16-000437.Angelea\PRE16-000437 PSE Substation Planning Comments.docx Talbot Project Narrative • Project Name: Talbot Hill Substation Improvements • Proposed Scope of Work: The proposal is to rebuild a portion of the Talbot Hill Substation, to replace aging equipment and provide more reliability for the transmission lines connected to the substation. The existing control house will be demolished and a new control house will be constructed in its place. The existing 230kV substation equipment inside the fence will be removed, including steel structures and foundations. The new equipment will be reconfigured to create a more efficient and more reliable substation and allow for flexible functioning of the system. Some transmission line work outside the substation fence may be required however no additional transmission lines will be added with the rebuild of this project. A new storm drainage system will be constructed within the fenced area and a detention pond will be installed south of the southerly substation fence. The substation footprint will remain unchanged. The storm improvements will require the removal of 120 trees. Additional driveway improvements are required to allow larger vehicle access to the substation. • Size: The project site totals 50.4 acres. In order to accomplish this total disturbed area will equal approximately 227,370 square feet. The cut will be about 11,500 cubic yards and fill of about 9,000 cubic yards. After construction the area of impervious surface will equal about 78,131 square feet and the pervious surface: 149,238 square feet. • Location: The site is located at 2400 S Puget Drive on parcels 2023059003, 2023059066 and 2023059064. • Land Use Permits Required: Site Plan Review with SEPA. Hearing Examiner Conditional Use Permit • Zoning designation for site: Residential -8 • Zoning for surrounding properties: Residential-8, Resource Conservation • Current Use: Utility • Special site features: Sensitive slopes, landslide hazards and coal mine hazards mapped • Soil type and drainage conditions: See attached drainage report • Proposed Use: Utility, unchanged • Total estimated construction cost: Unknown at this time • Fair market value of proposal: $6.7M • Trees to be removed: There are 97 significant trees on-site -80 at the stormwater pond site and 17 in the area of selective removal. We are proposing to remove 63 significant trees and retain 34. See attached arborist report for detailed information. • Job shack or trailer location: Unknown at this time; to be determined by contractor. • Proposed modification and stream or wetlands: There are no known wetlands or streams in the project vicinity. The substation improvements, with the exception of the stormwater pond, will remain within the existing fenced area. • Existing Access: There are no proposed off-site improvements, no land dedicated to the city. o Regarding Note 16 in Title Report: PSE's legal and physical access to all three parcels noted above is off the north side of Puget Drive SE at 2023059064. DEC O 6 20\6 Conditional Use Permit Justnication (Control House'): • Consistency with Plans and Regulations: The proposed use shall be compatible with the general purpose, goals, objectives and standards of the comprehensive plan, the zoning ordinance and any other plans, programs, maps or ordinances of the City of Renton. Response: The proposed use is not changing. The proposal includes replacing an existing control house within the Talbot Hill substation with a new control house. The use is compatible with the general purpose, goals, objectives and standards of the comprehensive plan, the zoning ordinance and any other plans, programs, maps or ordinances of the City of Renton. The Utilities Element of the Comprehensive Plan states: The Utilities Element guides future utility service within Renton's planning area and ensures that adequate utility services will be available to support existing and future development in the City. The goals and policies included in the Utilities Element are designed to promote efficient, cost effective utility service while meeting community needs and protecting both existing neighborhoods and the nature environment. The proposal complies with the following Comprehensive Plan goals and policies: Policy U-7: Non-City utility systems should be constructed in a manner that minimizes negative impacts to existing development and should not interfere with operation of City utilities. City development regulations should otherwise not impair the ability of utility providers to adequately serve customers. Goal U-0: Promote the availability of safe, adequate, and efficient electrical service within the City and its planning area, consistent with the regulatory obligation of the utility to serve customers. Policy U-72: Coordinate with local and regional utility providers to ensure the siting and location of transmission and distribution facilities is accomplished in a manner that minimizes adverse impacts to the environment and adjacent land uses. Policy U-73: Encourage electricity purveyors to make facility improvements and additions within existing utility corridors whenever possible. The proposed control house structure will replace an existing control house within the Talbot Hill substation fence. The proposal will have little to no impact on adjacent residential, as the existing use of the site will not change. The control house will replace an existing structure and be located adjacent to the existing structure. There are existing transmission corridors between the substation and neighboring residential properties. The City of Renton has determined that a control house is an accessory building to the substation use. The maximum wall plate in the R-8 zone for an accessory building is 12 feet. The proposed control house wall plate is 11 feet. However, since the overall height exceeds more than 6 feet above the wall plate (RMC 4-2-UOD.18 Vertical Projections from Wall Plates), the City determined that Conditional Use Permit approval is required for the new control house structure. The proposed control house will comply with all other applicable dimensional standards of the R-8 zone. As evidenced through this analysis, the proposed control house is consistent with the Conditional Use Permit decision criteria outlined in RMC 4-9-030.D. 1 A substation control house is a shelter containing equipment necessary to monitor and control the operation of the substation. At smaller or older substations this usually takes the form of a weather-protective cabinet, where maintenance and operation of control equipment can be performed by technicians standing outside, and reaching into, the cabinet {"house"). At larger or newer substations, which require more complex control and control-related communications equipment, this will necessarily take the form of a larger weather-protective shelter, which technicians may enter into to service and operate the equipment. This shelter is solely for the purpose of containing the control equipment; compared to other work or storage spaces, a control house is entered only while actively servicing the equipment it contains. • Appropriate Location: The proposed location shall not result in the detrimental overconcentration of a particular use within the City or within the immediate area of the proposed use. The proposed location shall be suited for the proposed use. Response: The proposed location of the control house will not result in detrimental overconcentration of a particular use within the City or within the immediate area. The proposed control house will replace an existing control house within the substation fence. The increased building square footage is minor compared to the scale of the substation footprint. The new control house will be located adjacent to the existing structure used for a control house and will not be substantially larger in size. • Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. Response: The proposed control house will not result in substantial or undue adverse effects on adjacent property. The proposed control house will replace an existing control house adjacent to the current structure location within the existing substation fence. The substation is located within a 50 acre site that contains several transmission lines. The substation is located over 460 feet from the nearest residential lot, resulting in no substantial impact to neighboring properties. • Compatibility: The proposed use shall be compatible with the scale and character of the neighborhood. Response: The proposed use is compatible with the scale and character of the neighborhood. Talbot Substation is an existing station that was constructed in the early 1960's. There is an existing control house structure within the substation fence that's use will be replaced with the new structure. The substation is over 460 feet from the nearest residential lot and completely surrounded by transmission corridors. The proposed control house is part of the same use that has been on the site for more than 50 years. • Parking: Adequate parking is, or will be made, available. Response: Adequate parking will be provided for the proposed control house. The existing and proposed control houses are visited by maintenance personnel on a weekly basis and not occupied fulltime. Adequate existing parking is provided for the substation use. • Traffic: The use shall ensure safe movement for vehicles and pedestrians and shall mitigate potential effects on the surrounding area. Response: The proposed control house will not result in increased traffic to and from the substation site. Impacts to the surrounding area are not anticipated. • Noise, Light and Glare: Potential noise, light and glare impacts from the proposed use shall be evaluated and mitigated. Response: The proposed control house will have minimal lighting to provide for safe entry and exit into and out of the building. The lighting will be directed downward and not directed offsite. Noise generated by the proposed control house is within the limits allowed by the City's noise ordinance. • Landscaping: Landscaping shall be provided in all areas not occupied by buildings, paving, or critical areas. Additional landscaping may be required to buffer adjacent properties from potentially adverse effects of the proposed use. Response: This conditional use approval only covers the proposed control house within the substation fence. The area outside the substation fence is landscaped in compliance with applicable codes and standards.

J The arborist report is required to accompany a Renton Site Plan Review submittal. It is developed to convey specific information regarding the trees proi:osed for removal, tree protection for trees to be retained and supplemental tree planting suggestions. I am coordinating the integration of tree removal, tree retention and tree protection into the landscape plans of the stormw.tter pond Assessment Methods The inventory of trees was performed on October 13, 2016. The inventory is tabulated in the tree table which includes an assignment of tree number, identification of tree species by common and botanical names, diameter at breast height (D BH) measurement, a condition assessment using five categories (Excellent, Good, Fair, Poor and Dead) based on visual tree inspection of each tree, comments specific to each trees condition and the proposal to either remove or retain the tree. In the case of trees with multiple stems, typically beaked hazelnut trees in this case, I've noted the approximate number of stems and the stems average size. Site description The site address is 3004 Beacon Way South. The location of the subject trees is along the south side and southea;t comer of the PSE Talbot Hill Substation. The land surface i~ undulating with vegetation typical of upland plant species. So:, figure 1. The majority of the trees are in good shape with the exception of the willow and alder; they have been damage::! by recent branch failures during the spring windstorms.

A stormwater detention pond is proposed lo he construe.tee! to the southeast of the substation, see figure 1 ahove. The grading of the stormwater pond will require significant trees to be removed, see the tree tahle for a list of signifiGmt and non-signifi=t trees to he ren1oved. The removal of these significant trees rariires a landscape pbnting effort to lxilster the view buffer planting hetween the neighbors lo the south and the substation to meet the Renton Municipal Code 4-4-070, si=:ifically section F .4.c and H.6.c which call for fully sight obscuring landscape visual buffer. The execution of this planting to meet the letter and intent of the code is diallenging in that the nearest location available for planting is between a maintenance road and the clearance zone of overhead transmission lines managed by Seattle City Light, see figure 2. In light of these mnstraints the fully sight-obscuring landscaped visual buffer is proposed to be 20 feet in width in two locations and contain a mixture of trees and large shrubs, some of which will mature to 35 feet tall.

The silt fmce should be placed at or outside of the trees dripline because it will need to be dug in to be correctly installed. In tree protection areas where silt fmce is not proposed, 4 foot tall orange construction fmce should be installed at the dripline or further from the trees to remain. This orange construction fmce should be the same as the limits of clli,turbance. The area of proposed selective tree removals should not rEqllire tree protection fmcing. Tree removals should be planned to control limb and main stern cuts to minimize damage to surrounding vegetation. Existing wildlife snags should be lo=ed in height to be less than their distance to the substation fmce. Supplemental visual buffer plantings The visual buffer plantings include Vine Maple, Western Serviceberry, Beaked Hazelnut, California Wax Myrtle, Silk Tassel and Strawberry Trees planted at 6 feet triangular on-cmter spacing. The vine maple and v,e,tern serviceberry are proposed to be 6 feet tall and the other plants are to be 5 gallon container at the time of iru,tallation. This visual buffer planting is 50% evergrem SJXdes to maximize the screening provided by the planting while also providing some variation to improve ecological services as well as aesthetics.

Could light or glare from the finished project be a safety hazard or interfere with views? Ihfill2l Based on the proposed lighting configuration, light or glare from the completed project would not present a safety concern or interfere with views. c. What existing off-site sources of light or glare may affect your proposal? Ihfill2] No existing off-site sources of light or glare will impact the proposed project. d. Proposed measures to reduce or control light and glare impacts, if any: Ihfill2] Substation lighting will be constructed in a way that will best minimize potential impacts. Security lighting within the substation will be shielded and facing down to prevent glare; to the extent possible, it will be mounted below the level of the surrounding fence and landscaping. The metal substation equipment will be a matte finish in order to absorb rather than reflect light. 14 Enter file location: 12. RECREATION a. What designated and informal recreational opportunities are in the immediate vicinity? ~ The property to the south which is owned by Puget Sound Energy is used by the Rolling Hills Community and includes a volleyball court, a baseball or multi-use field, a basketball court, and tennis courts.

Report Limitations and Guidelines for Use GEOENGINEER~ December 5, 2016 · Page ii File No. 0186-953-00 INTRODUCTION AND SCOPE This report summarizes the results of GeoEngineers, lnc.'s (GeoEngineers) geotechnical engineering services for the proposed improvements to the existing Puget Sound Energy (PSE) Talbot substation. The site is located west of Beacon Way South in Renton, Washington. The site is shown in relation to the surrounding area on the Vicinity Map, Figure 1, and the Site Plan, Figure 2. We provided a draft version of this report dated November 3, 2014 and a final version dated July 15, 2015. This revised final report incorporates additional critical areas recommendations and recommendations for the stormwater pond and supersedes our previous reports as described. We understand PSE is planning several phases of work at the existing 230-kV substation. Phase 1 involves the replacement of the existing 230 kV transformer located in the middle of the existing substation. The replacement transformer will be supported on a mat foundation. We understand Phase 1 began permitting at the end of 2014 and that the construction has been completed. In 2014, the plan for Phase 2 involved grading to expand the substation to the east, toward Beacon Way South and the Bonneville Power Administration (BPA) 230-kV Maple Valley substation located on the east side of Beacon Way South. Phase 2 also includes construction of new 230-kV dead-end towers as well as support of light equipment. The dead-end towers may be supported on either mat foundations or on drilled shafts. We understand that Phase 2 was scaled back from what was originally planned in 2014 and the substation footprint will not be expanded. We have left recommendations related to the expansion in our report for documentation purposes. We understand that stormwater infiltration is not planned at the site, based on the mapped soil conditions. However, a stormwater detention pond is planned southeast of the existing substation yard. Our geotechnical engineering services were completed in general accordance with our proposal dated August 19, 2014. Our scope of work included: • Completing seven borings at the site; • Completing laboratory testing on selected soil samples from the borings; • Providing geotechnical conclusions and recommendations for the proposed improvements; and • Preparing this report. FIELD EXPLORATION AND LABORATORY TESTING Fleld Exploratlons The subsurface conditions at the site were evaluated by completing seven borings (GEl-1 through GEl-7) to depths of 161/, to 311/, feet below existing site grades. The approximate locations of the borings are shown on the Site Plan, Figure 2. A detailed description of the field exploration program is presented in Appendix A. Laboratory Testing Soil samples were obtained during the exploration program and taken to GeoEngineers' laboratory for further evaluation. Selected samples were tested for the determination of percent fines, moisture content, GeoENGINEER~ December 5, 2016 ! Page 1 File No. 0186-9SJ-OO and grain size distribution (sieve analysis). A description of the laboratory testing and the test results are presented in Appendix A or on the exploration logs, as appropriate. SITE CONDITIONS Geology We reviewed available geologic maps, including the "Geologic map of the Renton quadrangle, King County, Washington" (D.R. Mullineaux, 1965) and the "Geologic Map of King County, Washington" (D. B. Booth et al. 2007). The soils mapped in the project vicinity are predominantly glacial till (Qvt), but include localized areas of ice-contact glacial deposits (Qvi) overlying the till. Glacial till typically consists of a dense to very dense heterogeneous mixture of sand, gravel, cobbles and occasional boulders in a silt and clay matrix that were deposited beneath a glacier. A zone of weathered till typically overlies the glacial till to depths of several feet below the ground surface. The ice-contact deposits tend to be similar in character to the till, but are less dense. Advance outwash is interpreted below the glacial till, based on the subsurface explorations and the geologic maps. Advance outwash generally consists of dense to very dense sand and gravel deposited by streams and rivers issuing from advancing ice sheets and subsequently overridden by a glacier. Surface Conditions The existing substation is bounded by Beacon Way South to the east, and undeveloped properties to the north, west and south. The substation is accessed by a gravel driveway off Puget Drive SE and connects to the south side of the existing substation. The substation yard is relatively flat and is surfaced with yard rock. Transmission lines generally run east and west from the substation. These include two sets of lines that connect this substation with the BPA Maple Valley substation to the east. The topography in the area of the proposed expansion is hummocky and irregular and is about 10 feet higher than the substation and approximately 15 feet higher than Beacon Way South. Vegetation in the expansion area consists of deciduous trees near the southeast corner of the existing substation and brush and blackberries in the other undeveloped areas. There is a city of Seattle water main that runs along Beacon Way South and an underground cable that connects the PSE and BPA substations. The approximate locations of the water main and underground cable are shown on the Site Plan, Figure 2. Other utilities may be present. Subsurface Conditions We explored subsurface conditions at the substation site by drilling seven borings (GEl-1 through GEl-7) at the locations shown on the Site Plan, Figure 2. Appendix A presents details of the field exploration and laboratory testing programs, including logs of borings. Borings GEl-1 through GEl-4 were completed inside the existing substation and encountered approximately 2 to 7 feet of fill overlying glacial till. The fill generally consisted of loose sand and silty sand with variable gravel content. The glacial till generally consisted of dense to very dense silty sand with variable gravel GEoENGINEER~ December 5, 2016 i Page 2 File No. 0186-953-00 content and extended to depths of 7 to 23 feet. Advance outwash consisting of very dense sand was encountered below the glacial till in all four borings and extended to the depths explored (21'12 to 31 V, feet). Borings GEl-5 through GEl-7 were completed in the area of the proposed expansion and encountered approximately 2 to 7 feet of fill consisting of loose sand and organic-rich topsoil and duff overlying glacial till. The glacial till generally consisted of dense to very dense silty sand with variable gravel content and extended to depths of 8 to 23 feet. Advance outwash consisting over very dense sand was encountered in all three borings below the glacial till and extended to the depths explored (16¥2 to 31 V, feet). Groundwater was not encountered during drilling, as noted on the exploration logs. These observations represent a short-term condition that may not be representative of the long-term groundwater conditions at the site. Groundwater conditions observed during drilling should be considered approximate. Groundwater level is anticipated to vary as a function of precipitation, season and other factors. CONCLUSIONS AND RECOMMENDATIONS Crltlcal Areas We reviewed the City of Renton online maps with regard to geologic critical areas including coal mine, erosion, flood, landslide and steep slope hazard areas. The site is not mapped in erosion or flood hazard areas. The site is mapped in a moderate coal mine hazard area. However, based on the depth of historical coal mining activity and the relatively shallow depth of the proposed improvements, it is our opinion there is a low coal mine hazard at the site. The site is mapped in a 25 to 40 percent steep slope area and in a moderate landslide hazard area. It is our opinion that the proposed improvements will not adversely affect the stability of the slopes in or around the site. Based on our evaluation it is our opinion the soils underlying the substation site have a low risk of liquefying under the design earthquake event. It is also our opinion that soils underlying the site have a low risk of lateral spread and earthquake-induced slope movement. The site is approximately 5 miles south of the Seattle Fault Zone, which is thought to have a recurrence interval on the order of 1,000 years. Based on the distance from the nearest mapped fault, it is our opinion there is a low risk of fault rupture at the site. Earthquake Engineering 2012 IBC Seismic Design Information We recommend the 2012 International Building Code (IBC) parameters for Soil Profile Type, short period spectral response acceleration (Ss), 1-second period spectral response acceleration (S1), and Seismic Coefficients FA and Fv presented in the following table: GEoENGINEER~ December 5, 2016; Page3 File No. 018&953-00 2012 IBC PARAMETERS 2012 IBC Parameter Soil Profile Type Short Period Spectral Response Acceleration, Ss (percent g) 1-Second Period Spectral Response Acceleration, S, (percent g) Seismic Coefficient, FA Seismic Coefficient, Fv Peak Ground Acceleration, PGA (percent g) Note: Recommended Value C 141.3 52.8 1.00 1.30 58.0 The above spectral response accelerations are based on data from the United States Geologic Survey (USGS) National Seismic Hazard Mapping Project. Shallow and Mat Foundations General It is our opinion the proposed structures (replacement 230 kV transformer, breakers, switches and other electrical equipment) may be supported on conventional spread footings or mat foundations bearing on either dense to very dense soils where present at foundation depth, or on a minimum of 2 feet of compacted structural fill in areas of loose to medium dense soils present at foundation depth. Due to space limitations, we understand drilled shafts are preferred for support of the dead-end towers. Our recommendations for drilled shaft foundations are discussed in the "Drilled Shafts" section. Bearing Pressure Allowable Stress Design (ASD). Spread footings may be designed using an allowable soil bearing pressure of 3,000 pounds per square foot (psf). Mat foundations may be designed for an allowable bearing pressure of 1,500 psf. The allowable soil bearing pressures apply to the total of dead and long-term live loads and may be increased by up to one-third for transient loads such as wind or seismic forces. A subgrade modulus of 180 pounds per cubic inch (pci) may be used for the design of mat foundations. Load and Resistance Factor Design (LRFD). A bearing capacity chart for spread footings is presented in Figure 3. We recommend the LRFD resistance factors listed in the table below be used when evaluating strength, service and extreme limit states for spread footings. The chart is based on a 5-foot wide footing with varying lengths and may conservatively be used for wider footings. The chart was developed in accordance with American Associate of State and Highway Transportation Officials (AASHTO) methods, in conjunction with Washington State Department of Transportation (WSDOT) standards, as summarized in the WSDOT Geotechnical Design Manual. LRFD SPREAD FOOTING RESISTANCE FACTORS UmltState Strength Service Extreme GEoENGINEER~ Shear Resistance to Sliding 0.8 1.0 0.9 Resistance Factor + Bearing 0.45 1.0 0.9 Passive Preesure Resistance to Sliding 0.5 1.0 0.9 December 5, 2016 Page 4 FlleNo. 0186-953-0D Embedment In general, we recommend that the bottom offoundations be embedded at least 24 inches below the lowest adjacent grade for frost protection. The foundation embedment depth may be reduced to 18 inches for small, lightly loaded footings where frost action will not affect equipment performance, or an additional 6-inch-thick layer of gravel that is not susceptible to frost may be placed below the foundations to achieve an embedment of 24 inches. The gravel should meet the requirements of "yard course" surfacing material presented in the "Structural Fill" section of this report. Settlement Provided all loose soil is removed and the subgrade is prepared as recommended under the "Construction Considerations" section below, we estimate that the total settlement of shallow foundations will be on the order of Y2 to 1 inch, with the higher end of that settlement range anticipated in the southwest corner of the substation that is underlain by looser soils. The settlements will occur rapidly, essentially as loads are applied. Differential settlements between comparably loaded foundations are expected to be less than Y2 inch. Lateral Resistance Lateral foundation loads may be resisted by passive resistance on the sides of foundations and by friction on the base of the foundations. For foundations supported on native soils or on structural fill placed and compacted in accordance with our recommendations, the allowable frictional resistance may be computed using a coefficient of friction of 0.4 applied to vertical dead-load forces. The allowable passive resistance may be computed using an equivalent fluid density of 250 pounds per cubic foot (pcf) (triangular distribution) if these elements are poured directly against compacted native soils or surrounded by compacted structural fill. The structural fill should extend out from the face of the foundation element for a distance at least equal to three times the height of the element and be compacted to at least 95 percent of the maximum dry density (MDD). The above coefficient of friction and passive equivalent fluid density values incorporate a factor of safety of about 1.5. Construction Considerations Following excavation for foundations, we recommend the condition of each footing excavation be observed by a qualified geotechnical engineer to evaluate if the work is completed in accordance with our recommendations and that the subsurface conditions are as anticipated. Areas of loose or soft soils present at the foundation subgrade elevation should be overexcavated to a maximum depth of 2 feet and replaced with compacted structural fill. In such instances, the zone of structural fill should extend laterally beyond the footing edges a horizontal distance at least equal to the thickness of the fill. A geotextile separator fabric may be used at the base of the overexcavation if loose/soft soils extend below the depth of the overexcavation. GeoENGINEER~ December 5, 2016 Page 5 File No. 0186-953-0.'.l Drilled Shafts General The proposed new 230-kV dead-end towers as well as lightly-loaded equipment may be supported on drilled shafts. We recommend that the drilled shafts extend to a depth of at least 15 feet below the existing ground surface. We should review the final dead-end tower locations when available and provide modifications to these recommendations if appropriate. Axial Capacity The applied axial loads on the drilled shafts for the dead-end towers are generally very small in comparison to the applied overturning moments, resulting from the tension in the wires along with possible ice and wind loading. The axial capacity of the drilled shafts in compression will be developed primarily from friction and end bearing in the medium dense to dense soils. Provided the drilled shafts are embedded at least 15 feet below the existing ground surface and into dense soils at the tip elevation, we anticipate that the allowable axial capacity for shafts at least 3 feet in diameter will be greater than 100 kips. Lateral Capacity The design of the drilled shafts will be governed by the lateral loads on the structures. The lateral capacity of the drilled shafts will develop from the stiffness of the drilled shaft and the lateral resistance of the soil surrounding the drilled shaft. We anticipate that the shafts will be designed using the L-PILE™ program. For evaluation of the lateral load behavior of the drilled shafts, the parameters in the tables below can be used as input soil parameters for the L-PILE™ program. The table below may conservatively be used for all the drilled shafts. LATERAL PILE ANALYSIS INPUT PARAMETERS SoUParam- Depth (ft) Soil Type (p-y curve model) Effective Unit Weight (lb/ft>) Friction Angle (degrees) p-y Modulus, k (lb/in 3 ) Drilled Shaft Settlement Layer 1 (flll) 0-7 Sand (Reese) 125 32 25 Layer 2 (glaclal tlll) Layer 3 (advance outwasb) 7-10 10-30 Sand (Reese) Sand (Reese) 135 135 38 38 200 150 We estimate that post-construction settlement of drilled shaft foundations, designed and installed as recommended, will be on the order of 1/2 inch or less. Maximum differential settlement of similarly loaded shaft foundations should be less than about one-half the post-construction settlement. Most of this settlement will occur rapidly as loads are applied. Construction Considerations Temporary casing may be required to keep the drilled holes open while drilling through the zones of sandier soils. The contractor may attempt to drill the holes without casing but should have temporary casing available for use if sloughing and caving occurs. Although not encountered in our explorations, cobbles and GEOENGINEERsg December 5, 2016 Page 6 File No. 0186-953-00 boulders may be present. The excavation contractor should be prepared for these conditions. Groundwater was not encountered in our explorations. However, as discussed above, groundwater may be present depending on the conditions at the time of construction and again the contractor should be prepared to deal with these conditions. We recommend that the drilled shaft foundation excavations be observed by GeoEngineers. Retaining Walls General We anticipate retaining walls may be used in conjunction with fill and cut slopes for grade transitions in the area of the substation expansion. Based on the available space, we anticipate concrete block walls (gravity and/or reinforced) will be the preferred wall type. This type of retaining structure is moderately settlement-sensitive, and suitable foundation support is important. We anticipate that some overexcavation of loose soils will be required to achieve suitable foundation support. We can provide recommendations for design of retaining walls once the wall geometries are better defined. Infiltration It may be possible to design stormwater facilities for infiltration, provided the base of the facilities extends to the advance outwash. This may be impractical considering the grades at the site, but we can provide infiltration recommendations if this appears feasible. Stormwater Pond We understand the stormwater pond is planned with 2H:1V (horizontal:vertical) side slopes and a depth of up to 7 feet in the middle. We recommend the side slopes be protected from erosion. Earthwork We understand that earthwork was planned as part of Phase 2 of this project but is no longer anticipated. Regardless, our recommendations for earthwork are presented below. Clearing Removal and demolition of existing site improvements and structures associated with the existing substation should include removal of foundation elements. Existing voids or new depressions created during demolition and site preparation should be cleaned of loose soil or debris and backfilled with compacted structural fill. Subgrade Preparation New foundation subgrade areas should be evaluated after site grading and foundation excavation is completed. Probing should be used to evaluate the subgrade; soft areas noted during probing should be overexcavated and replaced with compacted structural fill as described in the "Shallow and Mat Foundations" section. Erosion and Sedimentation Control Potential sources or causes of erosion and sedimentation depend upon construction methods, slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction sequencing and weather. GeoENGINEER~ December 5, 2016, Page 7 File No. 0186-953·00 Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce the potential for erosion and reduce transport of sediment to adjacent areas and receiving waters. Temporary erosion protection should include the construction of a silt fence around the perimeter of the work area prior to the commencement of grading activities. Permanent erosion protection should be provided by re-establishing vegetation or surfacing with rock. Until the permanent erosion protection is established and the site is stabilized, site monitoring should be performed by qualified personnel to evaluate the effectiveness of the erosion control measures and repair and/or modify them as appropriate. Provisions for modifications to the erosion control system based on monitoring observations should be included in the erosion and sedimentation control plan. Structural FIii Materials Materials used for support of structures or pavements or for utility trench backfill are classified as structural fill for the purpose of this report. Structural fill material quality varies depending upon its use as described below: 1. On-site soils may be used as structural fill to support substation equipment provided it can be appropriately moisture conditioned to achieve the required compaction. If on-site soils cannot be moisture-conditioned, imported gravel borrow for support of substation equipment should conform to PSE Base Course Aggregate Specification 1275.1310 as described in the following table: BASE COURSE GRADATION US Standard Sieve Size 3 inch 3.4 inch %inch :1/4 inch U.S. No. 40 U.S. No. 200 Percent Passing (by weight) 100 70-90 60-80 50-70 <30 <5 2. Structural fill placed as "yard course crushed aggregate" surfacing material should be angular crushed rock conforming to PSE Specification 1275.1330 as described in the following table: YARD COURSE GRADATION US Standard Sieve Size 1'f.1 inches 1inch %or% inch %inch GEOENGINEER~ Percent P-lng (by welgllt) 100 60to 100 Oto35 Oto 5 December 5, 2016 Page 8 File No. 0186.953·00 On-site Soils The on-site soils generally contain a significant amount of fines and are moisture sensitive. These soils generally meet the criteria for common borrow and are suitable for use as structural fill only if construction takes place during the drier summer months. Additional considerations for wet weather construction are presented below in the "Weather Considerations" section. FIii Placement and Compaction Criteria Structural fill should be mechanically compacted to a firm, non-yielding condition. In general, structural fill should be placed in loose lifts not exceeding 8 to 10 inches in thickness. Each lift should be conditioned to the proper moisture content and compacted to the specified density before placing subsequent lifts. Structural fill should be compacted to the following criteria: • Structural fill placed below foundations or to establish yard subgrade should be compacted to at least 95 percent of the MOD estimated in accordance with ASTM D 1557. We recommend that a representative from our firm be present during probing of the exposed subgrade soils in structure areas prior to the placement of structural fill and during the placement of structural fill. Our representative would evaluate the adequacy of the subgrade soils and identify areas needing further work, perform in-place moisture-density tests in the fill to evaluate if the work is being done in accordance with the compaction specifications, and advise on any modifications to procedures that may be appropriate for the prevailing conditions. Weather Considerations The on-site soils contain a sufficient percentage of fines (silt) to be moisture sensitive. If the moisture content of these soils is appreciably above the optimum moisture content, these soils become muddy and unstable. During wet weather, operation of equipment on these soils will be difficult, and it will be difficult to meet the required compaction criteria. The wet weather season generally begins in early November and continues through March in Western Washington; however, periods of wet weather may occur during any month of the year. The optimum earthwork period for these types of soils is typically July through October. If wet weather earthwork is unavoidable, we recommend that: • Structural fill placed during the wet season or during periods of wet weather consist of gravel borrow conforming to PSE Base Course Aggregate Specification 1275.1310. • The ground surface in and around the work area be sloped so that surface water is directed away from the work area. The ground surface should be graded such that areas of ponded water do not develop. Measures should be taken by the contractor to prevent surface water from collecting in excavations and trenches. Measures should be implemented to remove surface water from the work area. Temporary Slopes The soils encountered at the site are classified as Type C soil, in accordance with the provisions of Title 296 WAC (Washington Administrative Code), Part N, "Excavation, Trenching and Shoring." We recommend that temporary slopes in excess of 4 feet in height excavated in the on-site soils be inclined no steeper than 11/2H:1V. Flatter slopes may be necessary if localized sloughing occurs. For open cuts at the site we recommend that: GeoENGINEERs_O December5,2016· Page9 file No. 0186.953·00 • No traffic, construction equipment, stockpiles or building supplies be allowed at the top of the cut slopes within a horizontal distance of at least 5 feet from the top of the cut. • Exposed soil along the slope be protected from surface erosion using waterproof tarps or plastic sheeting. • Construction activities be scheduled so that the length of time the temporary cut is left open is kept as short as possible. • Erosion control measures be implemented as appropriate such that runoff from the site is reduced to the extent practical. • Surface water is diverted away from the excavation. • The general condition of the slopes be observed periodically by a geotechnical engineer to confirm adequate stability. Since the contractor has control of the construction operations, the contractor should be made responsible for the stability of cut slopes, as well as the safety of the excavations. All shoring and temporary slopes must conform to applicable local, state and federal safety regulations.

The borings were completed by Geologic Drill Exploration, Inc. of Spokane, Washington, on September 25 and 26, 2014. The locations of the explorations were estimated in the field by measuring distances from site features through taping and pacing. The approximate exploration locations are shown on the Site Plan, Figure 2. Borings The drilling contractor hand dug to a depth of 2 feet at each boring location to be clear of the grounding grid before drilling. The borings were drilled using a tracked Bobcat-mounted hollow-stem auger drill rig. The borings were continuously observed by a geotechnical engineer from our firm who examined and classified the soils encountered, obtained representative soil samples, observed groundwater conditions and prepared a detailed log of each boring. Soils encountered in the borings were visually classified in general accordance with the classification system described in Figure A-1. A key to the exploration log symbols is also presented in Figure A-1. The logs of the borings are presented in Figures A-2 through A-8. The logs reflect our interpretation of the field conditions and the results of laboratory testing and evaluation of samples. They also indicate the depths at which the soil types or their characteristics change, although the change might actually be gradual. The borings were backfilled in accordance with Department of Ecology standards. The top 6 inches of yard rock was replaced over the completed boring to match existing yard rock. Groundwater Conditions Observations of groundwater conditions were made during drilling and are noted on the exploration logs; these observations represent a short-term condition that may not be representative of the long-term groundwater conditions at the site. Groundwater conditions observed during drilling should be considered approximate. Laboratory Testing Soil samples obtained from the field explorations were transported to our laboratory and examined to confirm or modify field classifications, as well as to evaluate index properties of the soil samples. Representative samples were selected for laboratory testing consisting of the determination of the percent fines (material passing the U.S. No. 200 sieve), moisture content and grain size distribution (sieve analysis). The tests were performed in general accordance with test methods of the ASTM International (ASTM) or other applicable procedures. Percent Passing U.S. No. 200 Sieve Selected samples were "washed" through the U.S. No. 200 mesh sieve to determine the relative percentages of coarse and fine-grained particles in the soil. The percent passing value represents the percentage by weight of the sample finer than the U.S. No. 200 sieve. These tests were conducted to verify GEoENGtNEERs_O December 5, 2016 Page A-1 me No. 0186-953·00 field descriptions and to determine the fines content for analysis purposes. The tests were conducted in general accordance with ASTM D 1140, and the results are shown on the exploration logs at the respective sample depths. Moisture Content Testing Moisture content tests were completed using ASTM D 2216 for representative samples obtained from the explorations. The results of these tests are presented on the exploration logs at the depths where the samples were obtained. Sieve Analyses Sieve analyses were performed on selected samples in general accordance with ASTM D 422 to determine the sample grain size distribution. The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. The results of the sieve analyses were plotted, were classified in general accordance with the Unified Soil Classification System (USCS), and are presented in Figures A-9 and A-10.

Geotechnlcal Services Are Performed for Specific Purposes, Persons and Projects This report has been prepared for the exclusive use of Puget Sound Energy and their authorized agents. This report may be made available to prospective contractors for their bidding or estimating purposes, but our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfill the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic report is unique, prepared solely for the specific client and project site. Our report is prepared for the exclusive use of our Client. No other party may rely on the product of our services unless we agree in advance to such reliance in writing. This is to provide our firm with reasonable protection against open-ended liability claims by third parties with which there would otherwise be no contractual limits to their actions. Within the limitations of scope, schedule and budget, our services have been executed in accordance with our Agreement with the Client and generally accepted geotechnical practices in this area at the time this report was prepared. This report should not be applied for any purpose or project except the one originally contemplated. A Geotechnlcal Engineering or Geologic Report Is Based on a Unique Set of Project-Specific Factors This report has been prepared for the proposed improvements to the Talbot Substation located in Renton, Washington. GeoEngineers considered a number of unique, project-specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, do not rely on this report if it was: • not prepared for you, • not prepared for your project, • not prepared for the specific site explored, or • completed before important project changes were made. 1 Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org. GEoENGINEER~ December 5, 2016 Page B-1 File No. 0186-953·00 For example, changes that can affect the applicability of this report include those that affect: • the function of the proposed structure; • elevation, configuration, location, orientation or weight of the proposed structure; • composition of the design team; or • project ownership. If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as appropriate. Subsurface Conditions Can Change This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by man made events such as construction on or adjacent to the site, or by natural events such as floods, earthquakes, slope instability or groundwater fluctuations. Always contact GeoEngineers before applying a report to determine if it remains applicable. Most Geotechnical and Geologic Findings Are Professional Opinions Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. Geotechnlcal Engineering Report Recommendations Are Not Final Do not over-rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions. GEOENGINEER~ December 5, 2016, Page B·2 Flle No. 0186.953-00 A Geotechnical Engineering or Geologic Report Could Be Subject to Misinterpretation Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre-bid and preconstruction conferences, and by providing construction observation. Do Not Redraw the Exploration Logs Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering or geologic report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with GeoEngineers and/or to conduct additional study to obtain the specific types of information they need or prefer. A pre-bid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might an owner be in a position to give contractors the best information available, while requiring them to at least share the financial responsibilities stemming from unanticipated conditions. Further, a contingency for unanticipated conditions should be included in your project budget and schedule. Contractors Are Responsible for Site Safety on Their Own Construction Projects Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on-site personnel and to adjacent properties. Read These Provisions Closely Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to your project or site. Geotechnical, Geologic and Environmental Reports Should Not Be Interchanged The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, a geotechnical engineering or geologic report does not usually relate any environmental findings, conclusions or GEOENGINEER~ December 5, 2016 i Page 8-3 File No. 0186-953-00 recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project. Biological Pollutants GeoEngineers' Scope of Work specifically excludes the investigation, detection, prevention or assessment of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations, recommendations, findings, or conclusions regarding the detecting, assessing, preventing or abating of Biological Pollutants and no conclusions or inferences should be drawn regarding Biological Pollutants, as they may relate to this project. The term "Biological Pollutants" includes, but is not limited to, molds, fungi, spores, bacteria, and viruses, and/or any of their byproducts. If Client desires these specialized services, they should be obtained from a consultant who offers services in this specialized field. GEOENGINEER.g December 5, 2016 Page B-4 file No. 0186-953·00 ...
