Because of the presence of pavement and construction fill throughout the Project area, an archaeological survey was not feasible. Therefore, archaeological monitoring is recommended during several activities associated with the Project. This Archaeological Resources Monitoring and Inadvertent Discovery Plan describe the procedures to be used during construction activities associated with the Project. 1.1 Project Description Renton Municipal Airport proposes to replace the existing runway blast wall at the south end of Runway 34 within the Renton Municipal Airport, Clayton Scott Field. The existing blast wall is approximately 190 feet wide by 22 feet tall, and was originally built to provide jet blast protection for West Perimeter Road and Airport Way, both south of the airfield. The original design aircraft for the existing blast wall was the Boeing 727, necessitating protection from the center jet of the three-engine plane. The Boeing 727 has since been replaced at Renton by production of the Boeing 737, which has a dual-engine configuration and hence no center jet. Additionally, the existing blast wall penetrates Runway 34's Future Non-Precision Approach Surface by approximately 7 feet. In order to establish the Future 34:1 Approach Surface, the existing wall needs to be replaced with a new, lower blast wall which does not penetrate the Future Non-Precision Approach Surface. West Perimeter Road, located south of the blast wall, contains two bends in the alignment around the existing blast wall that hinders optimalline-of-sight. The new blast wall will be constructed in a curved configuration loosely following the curve of West Perimeter Road. The curved configuration will also provide the surrounding community with a unique focal point highlighting the historic importance of Clayton Scott Field. Several art pieces will be constructed on the pedestrian side of the wall. The art would consist of both static historic Boeing aircraft pieces as well as a kinetic art boundary. Landscaping would also be added to the pedestrian side of the wall. Landscaping and artwork would be in accordance with future capital improvement projects at the airport. Ground-disturbing activities associated with the Project include: 1) the demolition of the existing blast wall, perimeter fence, and pavement north of the wall; 2) installation of drainage features and electrical items; 3) installation of the new blast wall and security fence; and 4) grading, irrigation, and landscaping to the west and south of the new blast wall and grass berms south of 1 West Perimeter Road. The ground-disturbing activities will occur in an area that was previously disturbed by the construction of the existing wall, landscaping features, and road. In addition, the blast wall is situated on fill material from the development of the airport. The Project is being funded primarily with FAA Airport Improvement Program funds. All work will be performed in accordance with applicable FAA regulations and FAA Advisory Circulars. 1.2 ProjectLocation The Project is located on Parcel Number 0723059007 in Section 7, Township 23 North, Range 5 East in Renton, King County, Washington (Figure 1). The blast wall is near the northwest part of Renton Municipal Airport at 616 West Perimeter Road, Renton, WA 98057. The project area is located north of West Perimeter Road and generally northeast of the intersection of Airport Way and Rainier Avenue North. The cumulative project impact area, including all ground-disturbing activities, is approximately 1.97 acres. 1.3 Regulatory Context Cultural resources, which include archaeological, ethnographic, and historical sites, are protected by a variety of federal and state laws, rules, and regulations. The Project is being carried out by Renton Municipal Airport under federal funds from the FAA; and therefore, the Project is subject to Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended, and its implementing regulations (36 CFR 800). Section 106 requires federal agencies to identify and assess the effects of their undertaking on historic properties. Historic properties are those that are listed, or are eligible for listing, in the National Register of Historic Places (NRHP) and may include historic buildings or structures, archaeological sites, or traditional cultural properties. Eligible properties generally must be at least 50 years old, possess integrity of physical characteristics, and meet at least one of the four criteria of significance list in 36 C.F.R. § 60.4. In addition to federal laws and regulations, several Washington State laws address archaeological sites and Native American burials. The Archaeological Sites and Resources Act [RCW 27.53] prohibits knowingly excavating or disturbing prehistoric and historic archaeological sites on public or private land. The Indian Graves and Records Act [RCW 27.44] prohibits knowingly destroying American Indian graves and provides that inadvertent disturbance of human remains through construction or other activity requires re-interment under supervision of the appropriate Indian tribe. The Washington State Environmental Policy Act {SEPAl requires identification and evaluation of cultural resources as well as the development of plans for appropriate mitigation of cultural resources as part of the environmental review process. The Washington DAHP reviews projects subject to SEPA for their potential impacts to significant cultural resources and works with state agencies to avoid, minimize, and mitigate significant impacts. 2 USGS Remon (191]3) 7_~Io!I"'lIIpSer ... ~.

Project location map. 3 2.0 EXISTING AND POTENTIAL ARCHAEOLOGICAL RESOURCES The Project area and its vicinity was traditionally inhabited by the Ouwamish, who were one of over 50 southern Coast Salish tribal groups that traditionally frequented the Puget Sound Basin. The Ouwamish practiced a seasonal round that involved wintering in villages along the Ouwamish, Black, and Cedar Rivers as well as Lake Washington, Lake Union, and Elliot Bay, and camping during the warmer months to hunt, fish, and gather food (Suttles and Lane 1990; Ruby and Brown 1992). Intensive Euro-American historic use of the area occurred by the middle 1800s, when emigrants claimed land throughout the region and engaged in agricultural practices. Historic maps, including an 1865 GLO plat, show that the Project was located in the Cedar River fan and within the donation land claim (OLe) of H. H. Tobin. Previous cultural resource investigations have documented archaeological sites and isolates, demonstrating archaeological sensitivity within the vicinity of the Project. A search of records on file at the Washington OAHP identified 12 archaeological sites within one mile of the Project. The sites consist of five precontact, five historic period, and two mUltiple component archaeological sites. Nine of the archaeological sites are listed as unevaluated for listing in the NRHP, and one site is listed as ineligible for listing in the NRHP (Table 1). The five historic-period archaeological sites are 4sKIs38, the Columbia and Puget Sound Railroad grade; 4sKIs42, a debris scatter and concrete foundations; 4sKI7s9, ca. 1900-1940 debris scatter; 4sKI848, remnants of the Renton Glass Company Factory; and 4sKl1009, the Moses homestead consisting of a domestic debris concentration from the early to mid-20th century. The closest historic-period archaeological site to the Project is 4sKI009, the Moses Homestead, located approximately 0.15 south of the APE. The historic-period archaeological deposits at the Moses Homestead were concentrated between 30 and 120 centimeters below surface (cm) along the eastern edge of a former flood channel in front of the former house. No evidence of the house or associated outbuildings was observed (Shong and Rinck 2011). The precontact sites include 4sKIOs9, a late precontact-period camp or winter village; 4sKIs01 (Renton High School Indian Site), a shell midden site as identified in two strata; 4sKIs87, the ca. 500-300 BP Little Cedar River Fishing Station site (Oexudidew); 4sKI686, two precontact hearth features; and 4sKI1010 (Renton High School Ballfield Site), a camp with lithic material identified in two loci. Sites 4sKIs01 and 4sKI101O are located approximately 0.25 and 0.19 mile to the south of the APE, respectively. The archaeological deposits at 4sKIs01 were identified approximately three feet below the ground surface and separated by layers of culturally-sterile flood alluvium and represented several precontact occupations. The occupation surfaces, dating between 500 and 200 BP, were marked by discrete areas of burned sediments containing small fragments of charcoal, ash, and calcined fish, and mammal bone (Kramer et al. 4 2001; Lewarch 2006). The archaeological deposits at 45Kl1010 are composed of two distinct cultural components, Locus A and Locus B. Locus A consists of lithic artifacts restricted to the upper 60 cm of interbedded, non-organic silty sediments that overlay coarse sand and gravels, and Locus B consists of charcoal-rich sediments, fire modified rock, lithic artifacts, and calcined (burned) fish remains between approximately 140 and 200 cmbs (Shong and Rinck 2011). The coarse sand and gravel encountered during the field study demarcate the bottom of abandoned flood channels (flood event), which were in-filled with fine-grain alluvium. The occupation surfaces were found in the fine-grained flood alluvium above and below well-drained sandy soils (Shong and Rinck 2011). The background research suggests that the Project area has a potential for containing precontact, ethnohistoric, and historic-period archaeological resources. The Project is close to a number of late precontact and historic-period archaeological sites situated along the former banks of the Black and Cedar rivers. Despite the potential for archaeological findings within the undisturbed native material, the construction effort for the proposed projects is believed to be within the envelope of previously disturbed material and consequently does not pose a strong likelihood for archaeological findings. Due to the nature and depth of construction, URS recommends an on-site professional archaeologist be present when excavations occur below the fill material in native deposits. Boring logs and record drawings indicate fill material at least three feet below grade. Shallow surface excavation, clearing and grubbing, and similar grading will be governed by standard excavation protocols in relation to discovery of archaeological findings per Project contract specifications, Section 1.07.16(4}. 5 Table 1.

Archaeological monitoring will be conducted by a professional archaeologist who meets the Secretary of Interior's Professional Qualification Standards (36 CFR Part 61) and Washington State Statutes (RCW 27.S3.030[l1]). The professional archaeologist will be present to observe excavation activities and examine soil for potential archaeological resources. Monitoring will apply to the replacement of the runway blast wall and associated ground- disturbing activities (Figure 2). The airport's engineer or the construction contractor will brief the archeologist on any health and safety elements under which the archaeologist will perform the monitoring. The archaeologist will wear the proper personal protective equipment (e.g., hard hat, steel toed shoes, and safety glasses) as required for project health and safety. The airport will arrange for the archaeologist to brief the construction supervisor(s) about the procedures for the event of encountering archaeological deposits and human remains described herein. Renton Municipal Airport will inform all construction contractor(s) about the archaeological monitoring procedures and protocols. The airport will authorize the archaeologist to pause ground disturbing and earth moving construction activities periodically, as needed, for a closer examination of newly exposed sediments and/or historic-period and precontact period artifacts. When on site, the archaeologist shall check in daily with contractor and owner's representative to coordinate inspection activities. Archaeologists interacting with heavy equipment operations will comply with the following rules of engagement: a. Wear high-visibility protective vests and proper personal protective equipment when in work areas with any operating equipment. b. No standing or working in the equipment operator's blind spots. c. May only enter the work area of any operating equipment when: 1. They have attracted the operator's attention and made eye contact. 2. The operator has idled the equipment down, placed it in neutral, grounded engaging tools, and set brakes. 3. The operator gives the ground personnel permission to approach. d. Never walk or position themselves between any fixed object and operating equipment, or between two operating pieces of equipment. During construction, the archaeological monitor will examine soils, including excavations and back-dirt piles. Equipment will include, as appropriate, a shovel, trowel, and screen of X-inch mesh hardware cloth. The archaeologist will monitor for prehistoric or historic-period artifacts 8 or layers/lenses of organic material, or organically enriched soils that might indicate past human use. The airport will inform the construction contractor(s) about the archaeologist's monitoring work and this monitoring plan. The archaeological monitor will have copy of the monitoring plan and the health and safety plan on site. The archaeologist will record the details of the activities on monitoring forms for each day on which monitoring is conducted. Activities recorded will include descriptions of the construction area, excavation methods, cultural materials, soil profiles, sketches, and photographs. The archaeological monitor will submit a daily monitoring report to the Airport Engineer at the Renton Municipal Airport. When monitoring work has been completed, the archaeologist will prepare a final monitoring report discussing the methods and results of the work. The report will be submitted to the consulting parties. State of Washington Archaeological Site inventory Forms or Archaeological Isolate Forms will be included as necessary. These documents are confidential and exempt from disclosure under federal and state law (Section 304 of the NHPA; RCW 27.53.070 and RCW 42.56.300). 9 s.. ,.<-, E;". ,,,~,,' '" ><'0, ,;,:." ~(,.

Aerial of the runway blast wall and the area to be monitored. 10 4.0 PROTOCOL FOR INADVERTENT DISCOVERY OF ARCHAEOLOGICAL RESOURCES Potentially significant archaeological materials have been identified in the vicinity and may be present within the Project area. Types of archaeological materials that may be encountered could include, but are not limited to: flaked stone tools and lithic debitage, charcoal-rich sediments, fire-modified rock, concentrations of shell or faunal remains, organic materials (basketry, wooden posts, bone and wooden artifacts), and concentrations of historic-period bottles, ceramics, and cans. This section identifies the key responsibilities in the event of a discovery of an item of potential cultural significance during the Project. In the unanticipated event of a discovery, the following steps shall be taken: Step 1. Stop Work and Protect the Discovery Site. If any agency employee, contractor, or subcontractor believes that he or she has uncovered any cultural resources, all work within a minimum of 50 feet of the discovery ("discovery site") shall be stopped to provide for its security, protection, and integrity. The discovery site shall be secured. Vehicles, equipment, and unauthorized personnel will not be permitted to traverse the discovery site. Step 2. Notify Project Management. The individual making the discovery shall immediately contact the Airport Engineer and notify him or her of the discovery site. If the Airport Engineer is not immediately available, then the Airport Manager shall be contacted. Step 3. Notify Project Archaeologist. Immediately following the work stoppage and notification to Project Management, the Project Archaeologist, if not already present at the site, shall be contacted. Step 4. Assess Find. The Project Archaeologist shall be qualified as a professional archaeologist under 36 CFR Part 61 and RCW 27.53.030(11), and as such, is qualified to examine the find to determine if it is an archaeological site. If the Project Archaeologist determines that the find is not an archaeological resource, work may proceed with no further delay. If the Project Archaeologist determines the discovery potentially eligible for listing in the NRHP and the archaeological deposits cannot be avoided, archaeological site testing and evaluation to determine the significance of the cultural resource may be required. All work will be suspended in the area and the area protected until a permit from DAHP can be applied for and issued (RCW 27.53). Any type of archaeological testing or mitigation will depend upon the nature of the resource and would be developed as part of the DAHP permit, in consultation with the FAA and the appropriate Tribes. Step 5. Notify Additional Parties. If the discovery is determined by the Project Archaeologist to be a potentially NRHP-eligible archaeological resource, the Airport Engineer will continue with 11 notification to the FAA and DAHP within one (1) working day. If the remains are precontact or Native American, the FAA will notify and consult with the affected Tribes. If the find may relate to human remains or funerary objects, protocol outlined in the following section regarding human remains shall be enacted. Confidentiality of the find shall be maintained by Renton Municipal Airport and its contractors. Step 6. Obtain Consent to Proceed with Construction. Construction work shall not recommence at the discovery site until treatment has been completed and the FAA, DAHP, and the Tribes, as appropriate, have provided written or verbal consent to proceed. 12 5.0 PROTOCOL FOR INADVERTENT DISCOVERY OF HUMAN REMAINS If likely or confirmed human remains are encountered, all further ground-disturbing activities will cease immediately. Any human remains that are discovered during construction of the project will be treated with dignity and respect. The following procedures will be enacted: Step 1. Stop Work and Protect the Discovery Site. In the event that an employee, contractor, or subcontractor believes that he or she has uncovered any human skeletal remains, the Construction Supervisor will stop all work within a minimum of 50 feet of the remains to provide for their total security, protection, and integrity. Remains will immediately be covered with a tarp only, for temporary protection in place and to shield them from being photographed. The discovery location will not be left unsecured at any time, and confidentiality will be maintained by the Renton Municipal Airport and its contractors. The Project Archaeologist, if on site at the time of the discovery, can assist with implementation of these procedures. Step 2. Notify Project Management. The Construction Supervisor will immediately contact the Renton Municipal Airport's Engineer and notify him or her of the situation. If the Airport Engineer is not immediately available, then the Airport Manager will be contacted. Step 3. Notify Law Enforcement and County Coroner's Office. If human remains are known or suspected, the Airport Engineer or his/her designee will notify the City of Renton Police Department and the King County Medical Examiner's Office in the most expeditious manner possible (RCW 27.44; 68.S0; 68.60). The County Coroner will determine ifthe remains are human, whether the discovery site constitutes a crime scene, and will notify DAHP if the remains are non-forensic. Local law enforcement and/or the County Medical Examiner may need to access the discovery area to make any determinations and cannot be prohibited from doing so. Step 4. Notify Tribes, FAA, and DAHP. Concurrently, the Airport Engineer will immediately notify the affected Tribes, DAHP, FAA, and the Project Archaeologist. Per RCW 27.44, 68.S0, and 68.60, DAHP will have jurisdiction over non-forensic human remains from non-Federal and non-Tribal land and report them to cemeteries and affected Tribes. The State Physical Anthropologist will make a determination of whether the remains are Indian or Non-Indian and report that finding to any appropriate cemeteries and affected tribes (RCW 27.44, 68.50, 68.60). DAHP will handle all consultation with affected parties as to the preservation, excavation, and disposition of the remains. Step 6. Obtain Consent to Proceed with Construction. Ground-disturbing activities will not resume at the location of the discovery area and the construction buffer until the FAA, DAHP, 13 and the affected Tribes, as appropriate, have provided written consent to proceed. The archaeological monitor will prepare a report describing the treatment actions as part of the Monitoring Report. 14 6.0 REFERENCES DAHP (Washington Department of Archaeology and Historic Preservation) 2013 Washington State Standards for Cultural Resource Reporting.

Engineering Review April 09, 2014 The project area is located north ofW Perimeter Rd and is generally northeast of the intersection of Airport Way and Rainier Ave N. The 820 Building is located at 820 W Perimeter Rd, south of the entrance to the airport from Rainier Ave N (APN 0723059007). The demolition would result in the removal of approximately 800 cy of concrete, asphalt, and native base/foundation bedding rock. Grading would occur following demolition and would result in filling the site at-grade with approx. 1,400 tons of WSDOT crushed surfacing base course. The existing 22-foot high blast wall is located at the south end of the airport (616 W Perimeter Road, APN 0723059007). Regrading of the infield and grass areas would be required for the project. In addition, limited grading would occur within the blast pad pavement to provide positive drainage while lowering the end of the existing grade adjacent to the new blast wall in order to ensure that the new blast wall is below the Future Non-Precision Approach Surface. A new blast wall, approximately 12.75 feet in height would be constructed in the vicinity of the new wall. Approximately 500 cubic yards of fill would be needed for the project, and would be provided from approved borrow sources. The site is zoned 1M, and is located within the 500-year flood hazard area. There is a landslide hazard area south of the existing blast wall and a seismic area in the vicinity. Jan lilian Ph: 425-430-7216 email: jillian@rentonwa.gov Recommendations: Storm Drainage 1.

Because of the presence of pavement throughout the Project area, an archaeological survey was not feasible. Therefore, archaeological monitoring is recommended during several activities associated with the Project. This Archaeological Resources Monitoring and Inadvertent Discovery Plan describe the procedures to be used during construction activities associated with the 820 Building Demolition Project. 1.1 Project Description Renton Municipal Airport proposes to demolish the 820 building within airport property in Renton, King County, Washington. The 820 Building is located on the west side of the airport and north of the airport's maintenance building. The building contains, from ground up: first floor and second floor mezzanine. The building was originally constructed in 1963 as an electronics manufacturing facility known as Electronics Laboratory Building 5-14 for Boeing. However, over the years the primary use has changed, and the building is now vacant. The demolition of the 820 building includes the removal of the building from the airport property, removal of hazardous materials from the building, structural changes required due to connection of the building to the adjacent building, modifications to the existing utilities, and adjustments to the site necessary due to the building removal. The ground-disturbing activities, including the building demolition, the utility disconnects, and limited excavation to remove the column footings to 3 feet below ground surface, will occur in an area that was previously disturbed by the construction of the original building. In addition, the 820 building is situated on fill material from the development of the airport. There are no plans at this time for new construction at the building site. The demolition of the 820 Building is anticipated to begin in March 2014, and the total duration of the demolition would be approximately 90 working days. 1.2 Project Location The Project is located on Parcel Number 0723059007 in Section 7, Township 23 North, Range 5 East in Renton, King County, Washington (Figure 1). The 820 building is near the northwest part of Renton Municipal Airport at 820 West Perimeter Road, Renton, WA 98057. The Project is located south of the airport entrance from Rainier Avenue North. The cumulative project impact area, including all ground-disturbing activities, is approximately 0.51 acre. 1 1.3 Regulatory Context Cultural resources, which include archaeological, ethnographic, and historical sites, are protected by a variety of federal and state laws, rules, and regulations. No federal funds, licenses, or permits are required for this Project; however, several Washington State laws address archaeological sites and Native American burials. The Archaeological Sites and Resources Act [RCW 27.53] prohibits knowingly excavating or disturbing prehistoric and historic archaeological sites on public or private land. The Indian Graves and Records Act [RCW 27.44] prohibits knowingly destroying American Indian graves and provides that inadvertent disturbance of human remains through construction or other activity requires re-interment under supervision of the appropriate Indian tribe. The Washington State Environmental Policy Act (SEPA) requires identification and evaluation of cultural resources as well as the development of plans for appropriate mitigation of cultural resources as part of the environmental review process. The Washington Department of Archaeology and Historic Preservation (DAHP) reviews projects subject to SEPA for their potential impacts to significant cultural resources and works with state agencies to avoid, minimize, and mitigate significant impacts. Although there is no Federal nexus for the 820 Building Demolition Project, regulations for implementing Section 106 of the NHPA (36 CFR 800) provide useful guidelines for this assessment. 2 .--} !'II ;j"' t // / '.

Project location map. 3 2.0 EXISTING AND POTENTIAL ARCHAEOLOGICAL RESOURCES The Project area and its vicinity was traditionally inhabited by the Duwamish, who were one of over SO southern Coast Salish tribal groups that traditionally frequented the Puget Sound Basin. The Duwamish practiced a seasonal round that involved wintering in villages along the Duwamish, Black, and Cedar Rivers as well as Lake Washington, Lake Union, and Elliot Bay, and camping during the warmer months to hunt, fish, and gather food (Suttles and Lane 1990; Ruby and Brown 1992). Intensive Euro-American historic use of the area occurred by the middle 1800s, when emigrants claimed land throughout the region and engaged in agricultural practices. Historic maps, including an 1865 GLO map, show that the Project was located in the Cedar River fan, and a historic trail extended approximately 0.25 mile to the south of the Project. Previous cultural resource investigations have documented archaeological sites and isolates, demonstrating archaeological sensitivity within the vicinity of the Project. A search of records on file at the Washington DAHP identified four archaeological sites within one mile of the Project. The sites consist of two historic-period and two precontact-era archaeological sites. All four of the archaeological sites are listed as unevaluated for listing in the NRHP (Table 1). The two historic-period archaeological sites are 45K1404, a military property consisting of an aircraft submerged in Lake Washington, and 4SK11009, the Moses homestead consisting of a domestic debris concentration from the early to mid-20th century. The historic-period archaeological deposits at the Moses Homestead were concentrated between 30 and 120 centimeters below surface (cm) along the eastern edge of a former flood channel in front of the former house. No evidence of the house or associated outbuildings was observed (Shong and Rinck 2011). The precontact sites are 45KIS01 (Renton High School Indian Site), a shell midden site as identified in two strata, and 45KIl010 (Renton High School Ballfield Site), a camp with lithic material identified in two loci. The archaeological deposits at 45KI501 were identified approximately three feet below the ground surface and separated by layers of culturally-sterile flood alluvium and represented several precontact occupations. The occupation surfaces, dating between 500 and 200 BP, were marked by discrete areas of burned sediments containing small fragments of charcoal, ash, and calcined fish, and mammal bone (Kramer et al. 2001; Lewarch 2006). The archaeological deposits at 45Kl1010 are composed of two distinct cultural components, Locus A and Locus B. Locus A consists of lithic artifacts restricted to the upper 60 cm of interbedded, non-organic silty sediments that overlay coarse sand and gravels, and Locus B consists of charcoal-rich sediments, fire modified rock, lithic artifacts, and calcined (burned) fish remains between approximately 140 and 200 cmbs (Shong and Rinck 2011). The 4 coarse sand and gravel encountered during the field study demarcate the bottom of abandoned flood channels (flood event), which were in-filled with fine-grain alluvium. The occupation surfaces were found in the fine-grained flood alluvium above and below well-drained sandy soils (Shong and Rinck 2011). The background research suggests that the Project area has a potential for containing precontact, ethnohistoric, and historic-period archaeological resources. The Project is close to a number of late precontact and historic-period archaeological sites situated along the former banks of the Black and Cedar rivers. Despite the potential for archaeological findings within the undisturbed native material, the construction effort for the proposed projects is believed to be within the envelope of previously disturbed material and consequently does not pose a strong likelihood for archaeological findings. Due to the nature and depth of construction, URS recommends an on-site professional archaeologist be present when excavations occur below the fill material in native deposits. Boring logs and record drawings indicate fill material at least three feet below grade. Shallow surface excavation, clearing and grubbing, and similar grading will be governed by standard excavation protocols in relation to discovery of archaeological findings per Project contract specifications, Section 1.07.16(4). 5 Table 1.

Archaeological monitoring will be conducted by a professional archaeologist as defined in RCW 27.53.030(11). The professional archaeologist will be present to observe excavation activities and examine soil for potential archaeological resources. Monitoring will apply to the 820 Building demolition and associated ground-disturbing activities (Figure 2). The airport's engineer or the construction contractor will brief the archeologist on any health and safety elements under which the archaeologist will perform the monitoring. The archaeologist will wear the proper personal protective equipment (e.g., hard hat, steel toed shoes, and safety glasses) as required for project health and safety. The airport will arrange for the archaeologist to brief the construction supervisor(s) about the procedures for the event of encountering archaeological deposits and human remains described herein. Renton Municipal Airport will inform all construction contractor(s) about the archaeological monitoring procedures and protocols. The airport will authorize the archaeologist to pause ground disturbing and earth moving construction activities periodically, as needed, for a closer examination of newly exposed sediments and/or historic-period and precontact period artifacts. When on site, the Archaeologist shall check in daily with contractor and owner's representative to coordinate inspection activities. Archaeologists interacting with heavy equipment operations will comply with the following rules of engagement: a. Must wear high-visibility protective vests and proper personal protective equipment when in work areas with any operating equipment. b. No standing or working in the equipment operator's blind spots. c. May only enter the work area of any operating equipment when: 1. They have attracted the operator's attention and made eye contact. 2. The operator has idled the equipment down, placed it in neutral, grounded engaging tools, and set brakes. 3. The operator gives the ground personnel permission to approach. d. Must never walk, or position themselves between, any fixed object and operating equipment, or between two operating pieces of equipment. During construction, the archaeological monitor will examine soils, including excavations and back-dirt piles. Equipment will include, as appropriate, a shovel, trowel, and screen of 1/4-inch mesh. The archaeologist will monitor for prehistoric or historic-period artifacts or layers/lenses of organic material, or organically enriched soils that might indicate past human use. The airport will inform the construction contractor(s) about the archaeologist's monitoring work 7 and this monitoring plan. The archaeological monitor will have copy of the monitoring plan and the health and safety plan on site. The archaeologist will record the details of the activities on monitoring forms for each day on which monitoring is conducted. Activities recorded will include descriptions ofthe construction area, excavation methods, cultural materials, soil profiles, sketches, and photographs. The archaeological monitor will submit a Daily Monitoring Report to the Airport Engineer at the Renton Municipal Airport. When monitoring work has been completed, the archaeologist will prepare a final monitoring report discussing the methods and results of the work. The report will be submitted to the consulting parties. State of Washington Archaeological Site inventory Forms or Archaeological Isolate Forms will be included as necessary. These documents are confidential and exempt from disclosure under Washington law, RCW 27.53.070 and RCW 42.56.300. 8 """,, ,'" l'~,t'''_'''~f.

Types of archaeological materials that may be encountered could include, but are not limited to: flaked stone tools and lithic debitage, charcoal-rich sediments, fire-modified rock, concentrations of shell or faunal remains, organic materials (basketry, wooden posts, bone and wooden artifacts), and concentrations of historic-period bottles, ceramics, and cans. This section identifies the key responsibilities in the event of a discovery of an item of potential cultural significance during the Project. In the unanticipated event of a discovery, the following steps shall be taken: Step 1. Stop Work and Protect the Discovery Site. If any agency employee, contractor, or subcontractor believes that he or she has uncovered any cultural resources, all work within a minimum of 50 feet of the discovery ("discovery site") shall be stopped to provide for its security, protection, and integrity. The discovery site shall be secured. Vehicles, equipment, and unauthorized personnel will not be permitted to traverse the discovery site. Step 2. Notify Project Management. The individual making the discovery shall immediately contact the Airport Engineer and notify him or her of the discovery site. If the Airport Engineer is not immediately available, then the Airport Manager shall be contacted. Step 3. Notify Project Archaeologist. Immediately following the work stoppage and notification to Project Management, the Project Archaeologist, if not already present at the site, shall be contacted. Step 4. Assess Find. The Project Archaeologist shall be qualified as a professional archaeologist under the RCW 27.53.030(11), and as such, is qualified to examine the find to determine if it is an archaeological site. If the find is confirmed to be an archaeological site and the archaeological deposits cannot be avoided, evaluation and testing to determine the nature of the cultural resource may be required. Work will be suspended in that area, and site testing will not take place without a permit from DAHP (RCW 27.53). Any type of testing or mitigation will depend upon the nature ofthe resource and would be developed as part of the DAHP permit. If archaeological resources are identified during monitoring, all work must cease in the area and the area protected until a permit from DAHP can be applied for and issued. Step 5. Notify Additional Parties. If the discovery is determined by the Project Archaeologist to be a cultural resource, Airport Engineer will continue with notification to DAHP, and if the remains are precontact or Native America, the affected Tribes within one (1) working day. If the find may relate to human remains or funerary objects, protocol outlined in the following 10 section regarding human remains shall be enacted. Confidentiality of the find shall be maintained by Renton Municipal Airport and its contractors. Step 6. Obtain Consent to Proceed with Construction. Construction work shall not recommence at the discovery site until treatment has been completed and the Tribes, DAHP, and/or jurisdictional agencies, as appropriate, have provided written or verbal consent to proceed. 11 5.0 PROTOCOL FOR INADVERTENT DISCOVERY OF HUMAN REMAINS If likely or confirmed human remains are encountered. all further ground-disturbing activities will cease immediately. Any human remains that are discovered during construction of the project will be treated with dignity and respect. The following procedures will be enacted: Step 1. Stop Work and Protect the Discovery Site. In the event that an employee. contractor, or subcontractor believes that he or she has uncovered any human skeletal remains, the Construction Supervisor will stop all work within a minimum of 50 feet of the remains to provide for their total security, protection, and integrity. Remains will immediately be covered with a tarp only, for temporary protection in place and to shield them from being photographed. The discovery location will not be left unsecured at any time, and confidentiality will be maintained by the Renton Municipal Airport and its contractors. The Project Archaeologist, if onsite at the time of the discovery, can assist with implementation of these procedures. Step 2. Notify Project Management. The Construction Supervisor will immediately contact the Renton Municipal Airport's Engineer and notify him or her of the situation. If the Airport Engineer is not immediately available, then the Airport Manager will be contacted. Step 3. Notify Law Enforcement and County Coroner's Office. If human remains are known or suspected, the Airport Engineer or his/her designee will notify the City of Renton Police Department and the King County Medical Examiner's Office in the most expeditious manner possible (RCW 27.44; 68.50; 68.60). The County Coroner will determine if the remains are human, whether the discovery site constitutes a crime scene, and will notify DAHP if the remains are non-forensic. Local law enforcement and/or the County Medical Examiner may need to access the discovery area to make any determinations and cannot be prohibited from doing so. Step 4. Notify Tribes and DAHP. Concurrently, the Airport Engineer will immediately notify the affected Tribes, DAHP, and the Project Archaeologist. Per RCW 27.44, 68.50, and 68.60, DAHP will have jurisdiction over non-forensic human remains from non-Federal and non-Tribal land and report them to cemeteries and affected Tribes. The State PhYSical Anthropologist will make a determination of whether the remains are Indian or Non-Indian and report that finding to any appropriate cemeteries and affected tribes (RCW 27.44, 68.50, 68.60). DAHP will handle all consultation with affected parties as to the preservation, excavation, and dispOSition of the remains. Step 6. Obtain Consent to Proceed with Construction. Ground-disturbing activities will not resume at the location of the discovery area and the construction buffer until the affected 12 Tribes, DAHP, and/or jurisdictional agencies, as appropriate, have provided written consent to proceed. The archaeological monitor will prepare a report describing the treatment actions as part of the Monitoring Report. 13 6.0 REFERENCES DAHP (Washington Department of Archaeology and Historic Preservation) 2013 Washington State Standards for Cultural Resource Reporting.

In 1963, the 820 Building was constructed to house an electronics laboratory to support its production of military aircraft for the United States Air Force. These aircraft included the Boeing KC-135 Stratotanker that was manufactured at the Renton facility. To support these endeavors, the company constructed Building 5-14 beside airport Apron "C" (now referred to as the 820 Building). Subsequent to its construction and in response to the changing production lines of the Renton Manufacturing Plants, Boeing repurposed the building to assist with the refitting of aircraft cabin doors for certain models of the Boeing 737 aircraft at a later date. When constructed in 1963, the two-story building was quickly erected using precast concrete wall panels that are often referred to as "tilt-up" walls and featured a flat roof. Concrete block was used solely on the east elevation of the building. The interior space consisted of a large open production space on the first floor accompanied by rooms for "military parts storage", "military platform bench test class", "shipping and receiving", men's room, and a boiler room. The second floor was subdivided into office space that included offices, equipment rooms, crew quarters, vendor eqUipment storage, planning offices, foreman's office, "USAF office" and a planning office. The field investigation revealed that most of the interior partitions within the building have been modified and due to the removal of interior equipment, the original and subsequent functions and use of the building are not readily apparent. The historical integrity of the 820 building has been significantly diminished since its construction in 1963. Boeing appears to have repurposed the building at least once in order to better support its manufacturing changes in the Renton Manufacturing Plant. These changes resulted in the reorganization of interior spaces on the first and second floor. When Boeing did not renew its lease with the city in 2005, all equipment once associated with the building was removed as well. With the reorganization of the interior as well as the removal of the equipment, the building's historical associations with Boeing and its Renton Manufacturing Plant are not effectively communicated. Furthermore, the building does not appear to be associated with significant historical events or people and it is not a good example of the building type. While associated with the growth and evolution of Boeing's Manufacturing Plant in the 1960s and the concomitant development of the Renton Municipal Airport, the building's lack of integrity and its inability to communicate its historical associations with these trends renders the building not eligible for the NRHP under Criteria A, B, and C. The 820 building is located near the northwest part of Renton Municipal Airport at 820 West Perimeter Road in Renton, Washington. The building is a two-story concrete panel (tilt-up) industrial building with 26,400 gross square feet of enclosed floor space. Constructed in 1963, the building exhibits a flat, asphalt -membrane covered roof and is distinguished by the minimal number of window and door openings. Four fixed, double pane glass windows set in aluminum frames are situated on the first floor of the east elevation. Three metal doors with single lights are asymmetrically positioned between the two sets of two windows. Roll-top service garage entries are situated on the west side of the building on both the first and second floors. The rear of the building features a one-story extension that contains a boiler room and transformer. The 820 Building is connected to the 800 Building via a corrugated metal roof. The breezeway can be accessed via either of the buildings or from the east and west. The second floor exhibits two sets of three aluminum-clad, dOUble-pane windows. Each set of windows is accompanied by a single metal door that allows entry on to the first floor roof. Page 3 of7 Major Bibliographic References: Monday, March 17, 2014 Historic Inventory Report Most of the exterior walls are 5-1/2" thick concrete. The walls were constructed using the "tilt-up" process wherein the concrete for the walls is cast flat, on top of the building floor slab, and is then lifted into place after the concrete has set. The exterior ofthe concrete panels are "smooth-troweled" concrete with paint finish. The interior surfaces of the exterior walls are finished with gypsum wall board (GWB) attached to the concrete panels with metal furring channels. There is no insulation in the wall assembly. One exterior wall (second floor East facing) is made of concrete block. This wall has paint finish inside and outside with no interior GWB finish. In a number of locations the exterior walls show signs of Significant water damage. Galvanized metal sheeting (approximately 5' square) interrupts the concrete wall surface on the north side ofthe building. This is a sheet metal closure covering an opening in the concrete wall. The purpose of the opening is uncertain, but may have been related to ductwork or production equipment which has subsequently been removed. On the interior, this opening is now obscyred by a pair of metal doors. The interior of the building consists of a large, production-like room on the first floor that rests directly on the original concrete slab. A series of support columns interrupt the space at regular intervals. The second floor exhibits several office spaces as well as an additional larger production-like room. Special electrical power systems were originally included to support production activities. Power panels for 400hz and 28 volt panels remain but the generators/converters for special power are no longer in the building. Otherwise the building is equipped with 120/208 panels throughout. Lighting at the first floor is provided with ceiling-mounted fluorescent fixtures arranged in continuous rows. Similar lighting is provided in some areas of 2nd floor, but for the most part the 2nd floor is lit with 2' x 4' fluorescent fixtures in a suspended ceiling grid system. Since originally constructed, the following alterations to the 820 Building have occurred: • A breezeway has been introduced at the south side of the building. • Minor partitioning changes have occurred at the first floor. • Substantial changes to partitioning and interior finishes have occurred at the second floor • Vinyl Asbestos Tile has been changed in several locations at the first floor. • Special power and manufacturing equipment that required and served 400hz and 28v power has been removed. • Guardrails have been added to the roof.

While no plans or records have been found to pinpoint the date of the 800 Building, original plans for the 820 Building confirm Building 800's presence on site in 1953. According to the current Renton Airport Director, Ryan Zulauf, the hangar was erected by the (James L.) Robertson Aircraft Corporation to make short takeoff and/or landing kits for aircraft. It was subsequently purchased by Boeing for storage related to the 737 refurbishment to add an additional door for aircraft used in European markets. Since its release by Boeing in 2005, the hangar appears to have supported the maintenance and storage of smaller commercial aircraft and helicopters. Originally called Building 5-50, the building was situated immediately south of Building 5-14 beside airport Apron "C". The building's construction reflects commonly used pre-engineered building components and plans. Using metal I-beams for vertical structural supports, the building also exhibits large steel beams along with more slender purl ins to carry the loads necessitated by the large open spaces the building encloses. It appears that building has served as a small aircraft and helicopter maintenance and storage building over time. It does not appear related to Boeing's large aircraft manufacturing plant and facility although it may have provided ancillary space to support Boeing's operations. While the building appears to maintain its historical integrity, the hangar does not appear significant as it does not convey its associations with significant events or people and it appears to be a common example of a pre-engineered structure. Even though the building was situated within the Boeing Lease Area of the Renton Municipal Airport, it remains unclear what function it served within Boeing's operations. So, while associated with the growth and evolution of Boeing's Manufacturing Plant in the 1950s and the concomitant development of the Renton Municipal Airport, the building's inability to communicate its historical associations with these trends renders the building not eligible for the NRHP under Criteria A, B and C. The 800 building is located near the northwest part of Renton Municipal Airport at 800 West Perimeter Road in Renton, Washington. The building (also known at the 5-60 Building) is a one story, small aircraft hangar located to the south of the 820 Building. The building, constructed in the late 19505, is entirely clad with raised seam metal and features a moderately pitched, gable roof sheathed with raised seam metal. The front or east of the building exhibits a single door and a series of sliding windows that provide light to an office space. The elevation also features a folding metal door, as well as a larger set of sliding, corrugated metal doors for aircraft. The remaining elevations exhibit, single, metal door entries but no windows with the exception of the south elevation that contains some additional double-pane fixed windows near the southeastern corner of the building. The interior consists of three bays. The southernmost bay has largely been enclosed and is used for storage and mechanical equipment. The rear (west) part of the bay remains open. The central and north bays consist of open work spaces. The bays are defined by steel I-beam posts that support longitudinal steel trusses that conform to the gable roof line. Transverse metal purlins run east -west. The space between the purlins is covered with insulation. A raised office space with windows facing the work space is situated at the west end of the work space and is accessed via a single set of metal stairs with a handrail. Renton Muncipal Airport.

The project area is located north of W Perimeter Rd and is generally northeast of the intersection of Airport Way and Rainier Ave N. The 820 Building is located at 820 W Perimeter Rd, south of the entrance to the airport from Rainier Ave N (APN 0723059007). The demolition would result in the removal of approximately 800 cy of concrete, asphalt, and native base/foundation bedding rock. Grading would occur following demolition and would result in filling the site at- grade with approx. 1,400 tons of WSDOT crushed surfacing base course. The existing 22-foot high blast wall is located at the south end of the airport (616 W Perimeter Road, APN 0723059007). Regrading of the infield and grass areas would be required for the project. In addition, limited grading would occur within the blast pad pavement to provide positive drainage while lowering the end of the existing grade adjacent to the new blast wall in order to ensure that the new blast wall is below the Future Non- Precision Approach Surface. A new blast wall, approximately 12.75 feet in height would be constructed in the vicinity of the new wall. Approximately 500 cubic yards of fill would be needed for the project, and would be provided from approved borrow sources. The site is zoned 1M, and is located within the SOD-year flood hazard area.

The project area is located north of W Perimeter Rd and is generally northeast of the intersection of Airport Way and Rainier Ave N (Exhibit 1). The 820 Building is located at 820 W Perimeter Rd, south of the entrance to the airport from Rainier Ave N (APN 0723059007). The existing 820 building is 30,000 SF in size. The demolition would result in the removal of approximately 800 cy of concrete, asphalt, and native base/foundation bedding rock. Grading would occur following demolition and would result in filling the site at-grade with approx. 1,400 tons of WSDOT crushed surfacing base course. The area would be graded flat and prepared with a sub-grade for the potential future development. At this time, it is unknown what would be developed in this area, additional SEPA review may be required for future development of the site. The existing 22-foot high blast wall is located at the south end of the airport (616 W Perimeter Road, APN 0723059007). Regrading of the infield and grass areas would be required for the project. In addition, limited grading would occur within the blast pad pavement to provide positive drainage while lowering the end of the existing grade adjacent to the new blast wall in order to ensure that the new blast wall is below the Future Non-Precision Approach Surface. A new blast wall, approximately 12.75 feet in height would be constructed in the vicinity of the new wall. Approximately 500 cubic yards of fill would be needed for the project, and would be provided from approved borrow sources. The proposed project would not change access to the Renton Municipal Airport and/or change any airplane use of the Airport's runway. The project is located in the Airport Influence Area, Protection Zone 1, Runway Protection Zone. All portions of the project would be required to comply with the Federal Aviation Regulations Part 77 Objects affecting navigable airspace. The applicant has indicated no trees would be removed from the project site and neither the 820 demolition and/or the blast would is within 200 feet of the Cedar River and Lake Washington (both which boarder the Airport). The site is zoned 1M, and is located within the 500-year flood hazard area. There is a landslide hazard area south of the existing blast wall and a seismic area in the vicinity of the project. I PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period.

Environmentallmpacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The project site is generally flat for both the blast wall and the 820 demolition. The steepest slope in the project site is associated with the berm located west ofthe existing blast wall between West Perimeter Road and Airport Way, which is approximately 15 -25 percent. According to the Natural Resources Conservation Service, the site is underlain by Urban Land. Re-grading of the infield and grass area would be needed for the blast wall replacement project. In addition, limited grading would occur within the blast pad pavement to provide positive drainage while lowering the end of the existing grade adjacent to the new blast wall to ensure that the new blast wall is below the future Non-Precision Approach Surface. Approximately 500 cubic yards of fill would be needed for the project. The 820 demotion would result in 800 cubic yards of concrete, asphalt, and native base/foundation bedding rock to be removed for the demolition. Upon completion of the demolition the site would be leveled and fill would be placed to prepare for future development. All projects would occur in areas of existing impervious surfaces and there would be no net increase in impervious surface after both projects. Mitigation Measures: No further mitigation needed Nexus: N/A 2. Environmental Health a. Environmental Health Hazards ERC Report.docx City of Renton Department of Community & omic Development RUNWAY BlAST WAll REPLACEMENT PROJECT AND 820 BUILDING DEMOLITION PROJECT Report of February 24, 2002 _nvironmental Review Committee Report WA14-000133, ECF Page40fS Impacts: The 820 Building is known to contain asbestos, heavy metals, lead, mercury, and polychlorinated biphenyls (PCBs). The workers' health will be protected during demolition activities by applicable regulations regarding removal of hazardous materials from the Puget Sound Clean Air Agency, Washington State Department of Labor and Industries, the Environmental Protection Agency, and the Washington State Department of Ecology. Mitigation Measures: No further mitigation needed Nexus: N/A b. Noise Impacts: Temporary short-term notices impacts are anticipated related to the construction activities. Based on the provided construction mitigation description, the 820 demolition is anticipated to take 90 working days and the wall reconstruction is proposed to occur between April of 2014 and June of 2014. The applicant has indicated construction would occur during daylight hours or between 7:00 am and 10:00 pm. Due to the existing ambient noise which is characterized of an operating airport, it is not anticipated that the proposed temporary construction noise would be noticeable beyond regular operations at the Airport. Mitigation Measures: No further mitigation needed Nexus: N/A 3. Historic and Cultural Preservation Impacts: A letter was received from the Department of Archaeology & Historic Preservation (DAHP) dated February 19, 2014. Based on this letter both the blast wall and the 820 building are in an area with high potential for archaeological resources. The blast wall is adjacent to the historic confluence of the Black and Cedar Rivers and is approximately 800 feet from a precontact archaeological site situated on a similar land form. The 820 building has a high probability to contain precontact resources however, the building itself is not a historic building. Finally, DAHP requests a profeSSional archaeological survey of both the blast wall replaced and the 820 building demolition. Based on the probability of cultural resources in the vicinity of the project and the comments received from DAHP, staff recommends two mitigation measures that would require an archaeologist on side during ground disturbing activities and the applicant complete a review to determine if the 820 building is of historic significance. Mitigation Measures: 1. An architectural historian shall conduct a review of the 820 building for historical Significance and complete a Determination of Eligibility prior to any ground disturbing activity for the demolition. The evaluation shall be provided to the Department of Archaeology & Historic Preservation. 2. The 820 Building demolition and Blast Wall reconstruction and archaeologies shall be on- site during all ground disturbing activities for archaeological monitoring. A memorandum shall be prepared for both sites by the archaeologist and copes of each memorandum shall be submitted to the Department of Archaeology & Historic Preservation, concerned Tribes and the Current Planning Project Manager.

The area has a high the potential for archaeological resources. Also the blast wall replacement area is adjacent to the historic confluence of the Black and Cedar Rivers and is approximately 800 feet from a precontact archaeological site situated on a similar landforro. Therefore, we request professional archaeological survey of both the blast wall replacement and the 820 building replacement. We request that these surveys be forwarded to DAHP and the interested Tribes for review prior to ground disturbing activities. We also recommend consultation with the concerned Tribes' cultural committees and staff regarding cultural resource issues. We are confused as to why the proponent proposes to conduct a Determination of Eligibility and/or prepare an historic property inventory forro for the 820 building when the checklist clearly states that there are not object of historic interest on the site per the DAHP database. The survey for the 820 building demolition is requested based on the high probability for the area to contain precontact resources since we do not have information that the building is historic. .

The following briefly describes the application and the necessary Public Approvals. DATE OF NOTICE OF APPLICATION: February 5, 2014 LAND USE NUMBER: 14-000133, ECF PROJECT NAME: Runway Blast Wall Replacement Project and 820 Building Demolition Project PROJECT DESCRIPTION: Applicant proposes to demolish the existing 30,000 sf 820 Building and an existing 22·foot high blast walt at the Renton Municipal Airport. The project area is located north ofW Perimeter Rd and is generally northeast of the intersection of Airport Way and Rainier Ave N. The 820 Building is located at 820 W Perimeter Rd, south of the entrance to the airport from Rainier Ave N (APN 0723059007). The demolition would result in the removal of approximately 800 cy of concrete, asphalt, and native base/foundation bedding rock. Grading would occur following demolition and would result in filling the site at-grade with approx. 1,400 tons of WSDOT crushed surfacing base course. The existing 22-foot high blast waH is located at the south end of the airport (616 W Perimeter Road, APN 0723059007). Regrading of the infield and grass areas would be required for the project. In addition, limited grading would occur within the blast pad pavement to provide positive drainage while lowering the end of the existing grade adjacent to the new blast wall in order to ensure that the new blast waif is below the Future Non-Precision Approach Surface. A new blast wall, approximately 12.75 feet in height would be constructed in the vicinity of the new wall. Approximately 500 cubic yards of fill would be needed for the project, and would be provided from approved borrow sources. The site is zoned 1M, and is located within the SOD-year flood hazard area. There is a landslide hazard area south of the existing blast wall and a seismic area in the vicinity. PROJECT LOCATION: 616 & 820 West Perimeter Road OPTIONAL DETERMINATION OF NON-SIGNIFICANCE, MITIGATED (DNS-M): As the lead Agency, the City of Renton has determined that significant environmental impacts are unlikely to result from the proposed project.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. Blast Wall Replacement: The project involves replacement of the existing blast wall at the south end of Runway 34, Renton Municipal Airport, Clayton Scott Field. The existing blast wall is approximately 190 feet wide by 22 feet tall, and was originally built to provide jet blast protection for West Perimeter Road and Airport Way, both south of the airfield. The original design aircraft for the existing blast wall was the Boeing 727, necessitating protection from the center jet of the three-engine plane. The Boeing 727 has since been replaced at Renton by production of the Boeing 737, which has a dual-engine configuration and hence no center jet. Additionally, the existing blast wall penetrates Runway 34's Future Non-Precision Approach Surface by approximately 7 feet. In order to establish the Future 34:1 Approach Surface, the existing wall needs to be replaced with a new, lower blast wall which does not penetrate the Future Non-Precision Approach Surface. West Perimeter Road, located south of the blast wall, contains two bends in the alignment around the existing blast wall which hinders optimalline-of-sight. The new blast wall would be constructed in a curved configuration loosely following the curve of West Perimeter Road. The curved configuration would also provide the surrounding community with a unique focal point highlighting the historic importance of Clayton Scott Field. Several art pieces would be constructed on the pedestrian side of the wall. The art would consist of both static historic aircraft pieces as well as a kinetic art boundary. The kinetic art would mimic the flowing of waves, while the static art would draw attention to the historical Boeing aircraft that have been integral to the establishment of Renton Municipal Airport. landscaping would also be added to the pedestrian side of the wall. landscaping and artwork would be in accordance with future capital improvement projects at the airport. This project is being funded primarily with FAA Airport Improvement Program funds. All work will be performed in accordance with applicable FAA regulations and FAA Advisory Circulars. 820 Building Demolition: The 820 Building is located on the west side of the airport and north of the airport's maintenance building. The building contains, from ground up: first floor and second floor mezzanine. The building was originally constructed in 1963 primarily as an electronics manufacturing facility known as Electronics laboratory Building S-14 for Boeing. However, over the years the primary use has changed and the building is now vacant. The 820 Building would be demolished. Demolition includes the removal of the building from the airport property, removal of hazardous materials from the building, ·5· 06/09 J:\Projects\R\Renlon Municipal Alrport\Renton On-Call\Task Orders\Subtask 1.11 SEPA Support\SEPA CheckUst\SEPA Checklist 012814.doc structural changes required due to connection of the building to the adjacent building, modifications to the utilities, and adjustments to the site necessary due to the building removal. 12. Location ofthe proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available.
