The GMA specifically lists five critical areas for which local governments must designate and develop protection and enhancement programs. These five areas are fish and wildlife habitat, wetlands, aquifer recharge areas, flood hazard areas, and geological hazard areas. Critical areas under the City of Renton’s Critical Areas Regulations include flood hazard areas, wellhead protection areas, steep slopes, landslide hazards, erosion hazards, seismic hazards, coal mine hazards, and wetlands and habitat conservation areas (Renton Municipal Code [RMC] 4-3-050B.1). Projects in these critical areas or associated buffers and structural setbacks are required to complete relevant plans or studies to demonstrate that they would not adversely affect these critical areas, buffers, or structural setbacks (RMC 4-3-050F.2). Project Description The University of Washington is proposing a change of use from office space to laboratory facilities in an existing structure in the Commercial Office zone. This change of use requires a Conditional Use Permit be acquired from the City of Renton. The subject parcel at 1601 Lind Avenue SW in Renton, Washington is 229,238 square feet (5.26 acres) in size (project area). The building is 200,680 gross square feet and has a footprint of approximately 40,253 square feet. The entire building is currently leased by the University of Washington. The first level of the building is currently occupied by UW Medicine Testing labs through an Administrative Conditional Use Permit (LUA21-000463). The proposed Medicine Testing Lab facilities, support offices, and amenities would occupy the remaining floors (2 through 5). Renovations to the interior of the building would be required to support the technical equipment and workflow. New finishes, ceilings, interior partitions, and doors (including card access security) would be required, in addition to new electrical, data, mechanical equipment, and sinks (hand-wash and lab use). Restrooms would be added or modified to support current accessibility standards. New air handling units that would provide 100-percent outside air for lab safety are required and would be either on the upper roof or at grade. An additional 20 bike lockers bike rake with 5 stalls would be installed in the parking lot near the southwest corner of the building by the vendor parking spaces and across from the proposed additional refuse and recycling enclosure. Two exterior generators—each with an upper size limit of 258 inches long by 96 inches wide by 170 inches high—would be anchored on a concrete slab. A thicker concrete slab would replace the existing concrete patio slab, roughly 190 square feet, for better support of the exterior generators. A 12 inch thick concrete masonry unit (CMU) enclosure would surround the exterior generators to reduce changes to the visual landscape and dampen noise during generator operation (Figure 1). All new structures would be installed in areas with currently paved surfaces at grade. Exterior generators would only operate during emergencies to maintain power as well as once a month for a minimum of 30 minutes for generator load testing or maintenance. The testing lab would contain equipment to perform several tests on samples collected in other locations and couriered to the facility via small vehicles such as cars and small panel trucks. Patients requiring testing are not expected to visit the site. The expected hours of operation would be 24 hours a day, 7 DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Introduction Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 2 March 2023 days a week and the lab would employ about 600 to 750 full-time staff during project operation (Appendix A, Site Survey and Design Plan).

The study area consists of three parcels. Parcels 334040-4006 and 334040-4004 contain a steel commercial office building and an associated asphalt parking lot owned by B H 1601 Lind Avenue LLC. Parcel 334040-4005 contains a subpower station owned by Puget Sound Energy. The total study area is 8.9 acres (approximately 387684 square feet) in the southwest quarter of Section 19, Township 23N, Range 5E and central coordinates 47.465098°-122.225913°. The study area is in a highly developed setting surrounded by Providence Health & Services to the south, a vacant building 1 to the northwest, SW 16th Street to the north, Lind Avenue SW to the east, and Raymond Avenue SW to the west (Figure 2).

Project Study Area DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 6 March 2023 Chapter 3 Results The section presents the desktop assessment results for the project. The results and conclusions expressed herein represent ICF’s best professional judgment based on publicly available science and information (see Chapter 2, Methods) as well as information provided by the applicant. U.S. Geological Survey Topographic Map The study area is shown on the 7.5-minute USGS Renton, WA topographic map (USGS 2020). The study area and immediate surroundings are relatively flat, with the vicinity sloping from east to west toward the Green River. Springbrook Creek is mapped as a waterway feature to the west between the study area and the Green River; Panther Creek is mapped to the south; and wetlands are to the south and east. Geologic Hazards No geologic hazards—such as erosion hazards, landslide hazards, slope stability, or coal mine hazards—were identified in the study area by the City of Renton Sensitive Area Maps or King County iMap (City of Renton 2014a, 2014b, 2014c, 2014d; King County 2020). The closest geological hazard, according to the City of Renton Sensitive Area Maps, is roughly 0.3 mile east of the study area along a north–south greater than 40-percent slope mapped as a high landslide and erosion hazard (Appendix B, Figures A–C). The nearest coal mine hazard was documented by the City of Renton and King County iMap a little over 0.3 mile southeast of the study area (Appendix B, Figure D). Based on this, there are no known or mapped surface indications or history of unstable soils in the immediate vicinity of the study area. In addition, the study area is relatively flat with no fill, and the project proposes no excavation or grading. The proposed generators would be in an existing paved area. Therefore, there should be little to no degree of risk by the project on or from geologic hazards. Hydrology and Flood Hazards The study area is in the Duwamish/Green Watershed (Water Resource Inventory Area 9, Lower Green River subwatershed, hydrologic unit code 17110013) (USGS 2019). The Green-Duwamish River is the largest surface water drainage in Water Resources Inventory Area 9, flowing over 93 miles from the Cascade Mountains and draining into Elliot Bay (King County 2016). Historically, this area was almost entirely valley bottom forests with associated floodplain wetlands (Collins et al. 2003). After European settlement in 1851, much of the watershed was logged and converted to agricultural use. From 1945 onward, agricultural land was replaced with residential, commercial, and industrial properties. From 1895 to 1980, the Green-Duwamish River was channelized and diked for channel navigation and flood control (King County 2016). The Green River and its watershed’s biotic integrity are classified as impaired (Ecology 2014). The study area is covered by the Green River Temperature Watershed total maximum daily load (Ecology 2011). The City of DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Results Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 7 March 2023 Renton holds a phase II stormwater permit (WAR04-5559), which regulates how much of the regulated pollutant it contributes through its discharges, in accordance with the Clean Water Act National Pollutant Discharge Elimination System. On a more local scale, the study area is in the Black River drainage basin. The upper basin largely drains the City of Kent to the south. The lower portions of the Black River drainage, where the study area is located, are mostly developed and characterized by humanmade drainages, ditches, and flood-control features, such as retention ponds (King County 2015).The study area is not in a regulatory floodway, an aquifer protection area, or wellhead protection area, and the nearest mapped Zone 2 2 is roughly 0.25 mile to the northwest (Appendix B, Figure F) (City of Renton 2020). In addition, the proposed project would not withdraw any groundwater from a well for any purpose, nor would any water or waste material be discharged to groundwater during project construction or operation. Therefore, the proposed project should not pose a risk to the City aquifer(s) or wellhead protection area. The part of the study area that would contain the proposed external generators is in the 100-year floodplain, or Zone AE, which is defined as having a 1-percent annual chance of flooding with a determined base flood elevation, based on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map for King County Washington and Incorporated Area (FEMA 2020) (Appendix B, Figure G–I). Further discussion of potential effects related to the floodplain are discussed below. Wetland and Stream Inventories There are no mapped wetlands or streams in the study area (City of Renton 2016; USFWS 2021; King County 2020). The nearest wetland feature mapped by the City of Renton Surface Water Classifications and Wetlands and the NWI is a seasonally flooded freshwater emergent wetland roughly 200 feet southeast of the study area in a vacant commercial lot (Appendix B, Figures J–K). This feature is not mapped in the King County iMap (Appendix B, Figure E). Springbrook Creek, which is designated as a shoreline of the state by the City of Renton, is the closest mapped surface waterway and is roughly 780 feet to the west of the study area. Rolling Hills Creek, a non-fish-bearing stream, is piped 680 feet to the south. No work would occur over, In, or adjacent to Rolling Hills Creek, Springbrook Creek, or any other waterway or drainage during project construction or operation. In addition, no fill or dredge material would be placed in or removed from surface water or wetlands during project construction or operation. Finally, project construction and operation would not require any surface water withdrawals or diversions. Therefore, it is expected that the proposed project would pose little to no risk to wetlands or streams. 2 Aquifer protection area zones are delineated relative to the amount of contamination risk, with Zone 1 having the highest level of risk, followed by Zone 1 modified, and then Zone 2 (City of Renton 2020). DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Results Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 8 March 2023 Fish and Wildlife Habitat The WDFW Priority Habitats and Species (PHS) map does not contain any documented priority wildlife habitat or species within or migrating through the study area (WDFW 2020). The PHS map documents steelhead (Oncorhynchus mykiss), Chinook salmon (Oncorhynchus tshawytscha), and residential coastal cutthroat trout (Oncorhynchus clarki) occurring and migrating in Springbrook Creek (noted as the Black River in the WDFW PHS report; Appendix C), with the creek also used for breeding by Coho salmon (Oncorhynchus kisutch). Coho salmon and residential coastal cutthroat trout were also documented as occurring and migrating in Panther Creek 0.4 mile south of the study area. Ecology’s Puget Sound Watershed Characterization Project maps the study area as providing poor salmonid and terrestrial habitat, with nearby open spaces providing little ecological integrity (Appendix B, Figures L–M) (Ecology 2019). Finally, according to the Washington Natural Heritage Program, no threatened or endangered plant species are documented within or near the area (DNR 2021). However, common reed (Phragmites australis) and poison hemlock (Conium maculatum) are considered Class B noxious weeds by King County and are mapped roughly 140 feet north of the study area (King County 2020). Based on the results of the desktop analysis, habitat for federally listed species does not occur within the project area, and the nearest occurrence of a federally listed species occurs 0.4 mile away. Net loss of ecological function and impacts on federally listed species and their habitat are not anticipated. Therefore, there is little to no risk to fish or wildlife and their associated habitats, and a Biological Assessment is not required. DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 9 March 2023 Chapter 4 Applicable Regulations Federal Regulations National Flood Insurance Program FEMA is primarily responsible for managing the National Flood Insurance Program (NFIP), which allows communities that develop in floodplains to purchase insurance based on an agreement that they will mitigate future flood risk through appropriate ordinances and enforcement. Under NFIP, any development in floodways within Zone AE is regulated so that the development is kept free of new or additional encroachments, whereby, when flooding does occur, it would not result in a substantial increase in flood heights to the floodplain or the surrounding area (no rise certification). As described in Hydrology and Flood Hazards in Chapter 3, Results, the study area is in a Zone AE floodplain but not in a floodway. FEMA recommends that critical facilities located in the floodplain develop operations plans and evacuation routes to mitigate risk during a flood event. FEMA is not responsible for land use decisions or actions not connected with NFIP. In Washington State, federal floodway management regulations are often eclipsed by more stringent development requirements mandated at the state and local levels. Endangered Species Act In the Puget Sound region, the National Marine Fisheries Service–issued NFIP Biological Opinion, which protects endangered species occurring in floodplains, provides additional protective measures that are required and must be considered during development within a floodplain (NOAA 2008). As described in Fish and Wildlife in Chapter 3, Results, habitat for federally listed species does not occur within the study area, and the nearest occurrence of a federally listed species is 0.4 mile away. Net loss of ecological function and impacts on federally listed species and their habitat are not anticipated. Therefore, there is little to no risk to fish or wildlife and their associated habitats, and a Biological Assessment is not required. State Regulations Revised Code of Washington—Floodplain Management Regulation Floodplain management in Washington State is regulated under the Revised Code of Washington (RCW) 86.16.020, which establishes that local governments are responsible for meeting NFIP requirements; state requirements must meet the minimum requirements set under the federal NFIP; and the state may issue regulatory orders. RCW 86.16.020 is applicable to the planning, DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Applicable Regulations Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 10 March 2023 construction, and operation of any project that may adversely affect a stream or body of water or affect life and property due to flood water. Growth Management Act As discussed previously, the GMA requires local counties and cities to develop, review, and update ordinances and regulations regarding frequently flooded areas to ensure public safety and habitat conservation. Local Regulations Renton Municipal Code Flood hazard areas are regulated under the City of Renton’s Critical Areas Regulations (RMC 4-3-050). Projects within mapped flood hazards are required to complete relevant plans or studies to demonstrate the proposed project would not adversely affect the floodplain (RMC 4-3-050F.2). The proposed project would be designed, installed, and operated to comply with the standards and requirements under RMC 4-3-050G.4 discussed below. General Standards New construction must comply with general standards listed under RMC 4-3-050G.4.c, which requires proposed developments to be: • Anchored in such a way as to prevent them from “flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads including the effects of buoyancy. (Ord. 5977, 8-10-2020).” o The proposed exterior generators would be anchored to a concrete slab to prevent flotation, collapse, or lateral movement resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy during a 100-year flood event. The generators would be sealed in compliance with the Renton Municipal Code Flood Hazard Area regulations for anchoring all new construction (RMC 4.c.i). Similarly, the new concrete slab would be installed so that they are anchored to the existing paved surface in such a way as to prevent flotation, collapse, or lateral movement resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy during a 100-year flood event. • Constructed using materials, utility equipment, methods, statutes, codes, rules, regulations, and practices that minimize flood damage. o The exterior generators would be anchored to the concrete slab using a minimum of four 0.5-inch-diameter by 3-inch-long stainless steel expansion anchor bolts. The concrete slab would be reinforced with a steel rebar grid running 16 inches on center throughout. The rebar would be set at least 1 inch deep from the surface. To ensure a level surface, the concrete slab would have a height variance of 0.25 inch across the existing grade (Appendix A). This has been designed by a professional architect to meet the flood-proofing methods DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Applicable Regulations Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 11 March 2023 for nonresidential structures per 4G4diii(a). Specifically, the concrete slab would be elevated more than 2-feet above base flood elevation - as required by the ASCE 24 minimum elevation for Category IV, emergency generator, occupancy category - and the proposed generators would not be below the lowest floor. • Designed and/or elevated to prevent flood water from entering or accumulating within electrical, heating, ventilation, plumbing, air conditioning, or other service facilities. o The concrete slab would be a supportive protective structure for the new external generators. The exterior generators would be installed and anchored to be flush with the concrete slab preventing any debris or water that may otherwise accumulate under the generators. The concrete slab elevation would be roughly 4.5 feet above the base flood elevation (further discussion provided below). No modifications or changes would be made to the existing building exterior; therefore, the current engineering designs that prevent flood water from entering or accumulating within the building’s electrical, heating, ventilation, plumbing, and air conditioning systems would still apply. In addition, the applicant must work with the City of Renton to obtain a development permit and confirm that all permit requirements have been met (RMC 4-3-050G.4.c.vi). • A Conditional Use Permit, building permit, and applicable mechanical, electrical, and plumbing (MEP) permits would be obtained. Specific Standards Specific standards (RMC 4-3-050G.4.d.iii.a.1) for Zone AE require new construction and substantial improvement of any commercial, industrial, or other nonresidential structure to have the lowest floor elevated at least 1 foot above the base flood elevation or as required by American Society of Civil Engineers (ASCE) 24, whichever is greater. • The proposed project would be designed, installed, and operated to comply with the general standards listed under RMC 4-3-050G.4.d. Specifically, the FEMA flood map 53033C0978G shows the flood elevation for Zone A, or 100-year floodplain, at 20 feet above sea level (Appendix A and Appendix B, Figures G–I). Based on the survey conducted in February 2023, the existing patio elevation, where the new exterior generators and concrete slab would be installed, is roughly 24.5 feet above sea level using the North American Vertical Datum of 1988 (NAVD 88) (Appendix A). Therefore, the new exterior generators would be 4.5 feet above the base flood elevation. This is above the 2-foot exceedance as required by the ASCE 24 minimum elevation for Category IV, emergency generator, occupancy category. Compensatory Storage The proposed project must not reduce or alter the effective base flood storage volume within the floodplain (RMC 4-3-050G.4.g). • The proposed installation of the exterior generators is not anticipated to raise the base flood elevation, decrease the base flood storage volume, or affect adjacent properties. No new structures would be built below the base flood elevation; therefore, the project would not reduce or alter the effective base flood storage volume within the floodplain. Therefore, it is anticipated that compensatory storage would not be required. DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 12 March 2023 Chapter 5 Impacts and Mitigation Sequencing Alternatives Analysis The proposed generators are part of the necessary operations of the UW laboratory facilities and are required for staff health and safety. They provide necessary emergency backup power systems for critical equipment in the labs and emergency lighting and egress systems. Emergency power would be provided for “H” accessory occupancy storage rooms, cabinet exhaust ventilation, detection systems, emergency alarm, and temperature control systems. BSL-3 labs would also require emergency power for heating, ventilation, and air conditioning (HVAC); ventilation; and exhaust systems. Exhaust fans serving chemical fume hoods to prevent the release of hazardous substances in the general laboratory spaces would be on backup power systems. An in-building generator system is not practical due to the overall size, diesel fuel capacity, ventilation, and exhaust requirements. Sound and vibration requirements of laboratory microscopes and other sensitive equipment were also considered in evaluation of in-building generators. The 100-year floodplain zone covers much of the property, and a limited area is available to place generators outside of the zone. Areas outside of the flood zone would require remote location of generators far away from the building, creating more site disturbance, and would situate them close to either adjacent properties or public way. Ideally, the generators should also be installed as close as possible to the building’s electrical room to minimize the conduit runs. Temporary Impacts Noise during construction from the use of vehicles and equipment is anticipated between 5:00 am and 2:00 pm Monday through Friday for approximately 11 months. The majority of project construction noise would be contained within the interior of the building. Emissions from construction vehicles and equipment may also temporarily affect local air quality during construction of the project. Though emissions quantities have not been estimated, they are not expected to exceed local emissions standards. No construction vehicles would be refueled on site, and the quantity of hazardous materials contained in fuel or fluid reservoirs of construction vehicles would not exceed 20 gallons. Finally, based on the early start, some additional light would occur during construction between 5:00 am and 2:00 pm, Monday through Friday. Permanent Impacts Project operations would include a research and testing facility. Laboratory equipment and associated laboratory reagents would be appropriately stored and used on site to perform tests on samples. There would be no onsite hazardous substance processing and handling, or hazardous waste treatment and storage. All chemical waste would be collected and disposed of (i.e., it would not enter the plumbing waste system). DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Impacts and Mitigation Sequencing Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 13 March 2023 Emissions from the exhaust of laboratory fume hoods—as well as exhausted environmental air from the lab and office spaces—would occur. Laboratory fume hoods would provide a ventilated enclosure that would trap and exhaust vapors, gases, and nanoparticles generated during project operation as well as pull in fresh air, via building duct work. The exact chemicals that would require use of a fume hood are still being determined and would vary between medical labs or departments. Grossing stations would handle formalin, xylene, and alcohol. Generators, which would only be used in case of power outages, would emit nitrogen oxides, carbon monoxide, particulate matter, and hydrocarbons. Roof-mounted mechanical equipment would generate noise during testing and start up. Exterior generators would generate noise when operated, which would be only during emergencies to maintain power and once a month for a minimum of 30 minutes for generator load testing. In addition, exterior generators would be placed in a sound attenuation enclosure in the form of a 12 inch thick CMU wall on four sides. Finally, the new exterior generators would be within the 100-year floodplain (FEMA 2020). The proposed exterior generators would be installed and anchored on a concrete slab in currently paved surfaces. Both the generators and concrete slab would be installed at least 2 feet above the base flood elevation and would be anchored to prevent flotation, collapse, or lateral movement. Therefore, these new structural elements are not expected to increase flood hazard in the vicinity. As there are no changes to the existing building and parking lot storm drainage system, stormwater would continue to be collected on site to an existing catch basin before being conveyed to the city stormwater system. The project would not alter or otherwise affect drainage patterns on or in the vicinity of the site. Cumulative Impacts Cumulative impacts from the project were considered. The project would have minimal impacts on floodplains or other critical areas as a result of project elements. The new exterior structures would be relatively small in comparison to the currently developed area and would be installed more than 2 feet above base flood elevation. Therefore, this project—when combined with all other existing development—is not expected to increase the water surface elevation of the base flood more than 1 foot at any point within the community (Ord. 5977, 8-10-2020; Ord. 6084, 11-14-2022). Mitigation Sequencing Potential impacts from construction and operation of the project have been considered during the project design process. Any impacts that cannot be avoided, addressed by construction design, or minimized would require further mitigation. The subsections below discuss mitigation sequencing of temporary and permanent impacts through avoidance, minimization, and—if necessary—compensatory mitigation as required under RMC 4-3-050G.4.g.i. DocuSign Envelope ID: 05F46813-3C21-46CD-8D74-95403BA85B11 Integrity Energy Services, Co Impacts and Mitigation Sequencing Critical Area Assessment for the University of Washington Department of Laboratory Medicine and Pathology Testing Lab 14 March 2023 Avoidance Mitigation Measures The project has been designed to avoid any work within wellhead/aquifer protection areas, steep slopes, landslide hazards, erosion hazards, seismic hazards, coal mine hazards, streams, wetlands, or habitat conservation areas. No in-water work or work within a waterway or wetland footprint is required or would occur. Therefore, no temporary filling, dredging, or discharge into any waterbody or wetland would occur as part of project construction. No ground disturbance activities would occur, so there is no expected increased risk from geologic hazards. Minimization Mitigation Measures Best management practices and construction techniques would be implemented to reduce possible temporary impacts from noise and light. Impacts from noise would be reduced by starting and ending project construction early during the workday to reduce the likelihood that people would be near the project site early in the day (commercial area). Increased lighting would be outside of residential or aquatic or wildlife habitat settings. Therefore, no light or glare impacts from project construction are anticipated. During operations, impacts from chemicals, hazardous waste, or fumes would be mitigated through engineer design and best management practices, including appropriate storage, handling, and disposal of chemicals as well as installation and use of fume hoods. Occasional increased noise from mechanical equipment and generators would be reduced by the location of equipment and use of sound-attenuating enclosures for the external generators. Any increase in the flood hazard due to new structures in the FEMA 100-year floodplain has been minimized through engineering design. These measures include installing the new exterior project elements at least 2 feet above the base flood level as well as mounting anchors to the exterior generators and corresponding concrete slab to prevent buoyancy.

The proposed project would not affect wellhead/aquifer protection areas, steep slopes, landslide hazards, erosion hazards, seismic hazards, coal mine hazards, streams, wetlands, or habitat conservation areas because there are no such areas in or immediately adjacent to the project area. The project is located outside a designated floodway; therefore, a no-rise certification under FEMA is not required. The project is located above the base flood elevation; therefore, no compensatory storage is required. Based on the design, installation, and operation of the exterior generators and concrete slab, the proposed project would comply with federal, state, and local floodplain management requirements and would have a negligible effect on flood risk. No additional impervious surfaces would be created from project construction. Therefore, changes to the existing surface water, groundwater, runoff water, and drainage pattern impacts are not anticipated. Based on distance from fish-bearing waterways or wildlife habitat—and because there are no known occurrences of threatened or endangered species in the study area—the proposed project would not affect state- or federally listed special-status species. Therefore, no compensatory mitigation, short-term or long-term monitoring, contingency plans, or security requirements are necessary.
