(BSW) submitted a Habitat Management Plan (HMP) for the Ponderosa Ridge Planned Unit Development (PUD) Preliminary Plat located in the NW comer of Section 5, T24N, R44E, W.M. (Figures 1-3). The west half of the 2004 Ponderosa Ridge PUD was in Spokane County and the east half was in the City of Spokane Valley. Part of the 2004 project was constructed in the County (west) half of the project when the plat expired. No work was completed in the City of Spokane Valley. A new Preliminary Plat for the site must be approved before the remainder of the development can be completed. The currently proposed Ponderosa Ridge East Preliminary Plat is the east half of the 2004 project. The proposed Preliminary Plat consists of 81 lots on the 16.95 acre parcel (Figure 4). Open space is provided in six tracts with a total combined area of 1.21 acres. Under mandate of the Washington State Growth Management Act, the City of Spokane Valley Municipal Code adopted Title 21: Environmental Controls. Section 21.40: Critical Areas mandates the protection of wetlands, fish, wildlife, and habitats. The intent of these regulations is to avoid, minimize, rectify, reduce, or compensate for impacts arising from land development and other activities affecting critical areas. The conclusions in this report are based on an evaluation of habitat and species data from Federal, State, and Local jurisdictions, an evaluation of construction plans and specifications for the project, a literature review, and field investigations by the author of this report. The project area was investigated for the following Federally listed species (Appendix 1). The project will have no effect on the Threatened species Bull Trout or proposed Bull Trout Critical Habitat. The project will not result in the destruction or adverse modification of potential, designated, or proposed Critical Habitat or Essential Fish Habitat for any fish species. The project will have no effect on the threatened species Spalding's silene or the Yellow-billed cuckoo. The project will have no effect on the Candidate species Monarch butterfly. There will be no significant adverse effect on a.ny 11sted Species of Concern~ The priority habitats and species of Spokane County are adopted from the Washington State Priority Habitats and Species Program (PHS) (WDF&W 1996). The Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species mapped for the site include White-tailed deer, Rocky Mountain Elk, the Gray Wolf, and Shrub/Steppe habitat (Appendix 2). Only the White-tailed deer will be affected by this project. The Department of Natural Resources (DNR) Water Type Map depicts a Type N and a Type U Water on adjacent property to the west (Figure 5). The DNR mapped Type N water is over 400 feet from the Ponderosa Ridge East property, so the buffer does not encumber the subject property. The Type U Water is depicted on the National Wetland 1 Ponderosa Ridge East site location map FJ ji.J r L / --~~IS;l'l Legend 5126122, 9:54 AM City of Spokane Valley Zoning hj""r e. ::<.

The map does not depict the accurate location of the draw and the mapped wetland/stream does not exist. Even if the mapped stream/wetland did exist at the mapped location the associated buffer would not encumber the Ponderosa Ridge East Preliminary Plat. The Ponderosa Ridge East Preliminary Plat is not encumbered by a wetland, stream, or the buff er associated with a stream or wetland. The Critical Areas map designations listed for the site require a qualified biologist to field verify the accuracy of all mapped designations, determine if the proposed development would have adverse impacts on a priority habitat or species, and prepare a Habitat Management plan that addresses the associated issues. 2.0 SITE AND HABITAT DESCRIPTION In 2004, Biology Soil and Water, Inc. (BSW) submitted a Habitat Management Plan (HMP) for the Ponderosa Planned Unit Development (PUD) Preliminary Plat. The 2004 Preliminary Plat proposed 82 lots in the City of Spokane Valley (east half) and 100 lots in Spokane County (west half). When the plat expired, only part of the project had been constructed in the County portion of the project and none of the project had been constructed in the City of Spokane Valley. The portion constructed in the County before the plat expired was named Ponderosa Ridge I. In 2022, a Preliminary Plat for Ponderosa Ridge II was submitted to complete construction of the Spokane County part of the original 2004 plat. The currently proposed Ponderosa Ridge East Preliminary Plat is for that portion of the original 2004 plat located in the City of Spokane Valley. The Ponderosa Ridge II development defines the West border of the Ponderosa Ridge East property. Existing residential development on the south side of 44th Avenue, west side of Farr Road, and north side of Holman Road define the north, east, and south sides of the property respectively. The 2004 Habitat Management Plan (HMP) proposed N/S wildlife travel corridors through the west part of the project located in Spokane County. The topographic draw that bisects the County portion of the site from north to south was protected as natural travel corridor with forested habitat utilized by wildlife. A powerline easement provides an alternative wildlife travel route through the northwest part of the site. In 2004, no travel corridor was proposed for the City (east) part of the project because it was already bordered by residential development on the north, east, and south sides and construction of the County part of the project would block wildlife access from the west. In Spokane County, homes already constructed on the east and west sides of Ponderosa Lane extend about 850 feet south from 44th A venue. The proposed Ponderosa Ridge II development will extend Ponderosa Lane south to the south end of property with new home constructed on the east and west sides of that street. The completion of that development phase in Spokane County will block wildlife access to the Ponderosa Ridge East site from the west. Deer, elk, coyotes, wolves, bear, cougars, racoons, skunks, and other small mammals will only be able to enter the Ponderosa East development by crossing streets and yards in surrounding residential neighborhoods. A wildlife travel corridor that links Ponderosa Ridge East to habitat patches on adjacent properties is not an option. Any open space tract created within the project limits must start within residential 7 June 2, 2022 Wetlands D D Estuarine and Marine Deepwater [] D Estuarine and Marine Wetland D Freshwater Emergent Wetland • Freshwater Forested/Shrub Wetland D Freshwater Pond D Ponderosa Lake Other Riverine This map is for general reference only. The US Fish and Wildlife Service is not responsible for the accuracy or currentness of the base data shown on this map. All wetlands related data should be used in accordance with the layer metadata found on the Wetlands Mapper web site. National Wetlands Inventory (NWI) This page was produced by the NWI mapper development and end in residential development. The Ponderosa East phase of the development includes 6 open space tracts with a combined area of 1.21 acres. All 6 of the tracts provide only small, isolated fragments of potential habitat for birds with no functional access routes or habitat value for large mammals. The site is currently dominated by an open canopy, mixed age class, Ponderosa pine overstory. Small patches of aspen/snowberry habitat type are scattered along the hillside. Individual aspen patches on the subject property are considerably less than two acres in area so they do not meet the WDF&W definition of Priority Habitat. Large patches of snowberry and service berry dominate the shrub understory. Rose, ocean spray, hawthorn, and Oregon grape are also well represented. The shrub clusters provide protective cover and browse opportunities for deer, foraging opportunities for birds, and open space for resident and migratory species. The presence of a small amount of knapweed indicates a minor degree of historical disturbance. 3.0: SITE INVESTIGATION FINDINGS 3.1 Vegetative Species Observed at the Site Upland tree, shrub, forb, and grass vegetative classes identified at the site are described in Table 1. No rare, sensitive, endangered, or otherwise protected plant species were identified. Table 1. Plant Species.

Presence of animals: A systematic search of the site and adjacent one- quarter mile perimeter was conducted once early in the early morning and two times in the evening. Investigation for sign: The site was also investigated for signs of elk and white-tailed deer presence such as trails, scat, beds, scrapes/rubs, browsed vegetation, wallows, etc. Perimeter survey and habitat summary: A one-quarter mile perimeter beyond the property boundary was assessed to determine utilization of habitat adjacent to the property and off-site influences on the elk and white-tailed deer populations. Elk and white-tailed deer habitat was assessed and is summarized below. 4.0 USF & W Listed Species The USFWS and NMFS species lists were accessed on their websites on 61212022. No NMFS species are listed for the vicinity. The USF&W list indicated the potential presence of the species and critical habitat(s) shown in Table 2 (and in Appendix 1 ). 1 Tab e 2. USFWS listed species and critical habitats potentiallv present in the vicinity of Species ESU/DPS Federal Status Designated Critical Habitat Bull trout Salvelinus confluentus Col River Threatened Yes Spalding's silene, Silene spaldinRii Threatened No Monarch Butterfly Danaus p/exivvus Candidate No Yellow-billed cuckoo, Coccyzus Threatened No americanus, 10 4.1: Bull Trout (Salvelinus confluentus) Threatened The U.S. Fish and Wildlife Service (USF&WS) lists the Columbia River population of bull trout as threatened. Small pockets of bull trout are present in isolated habitat fragments in the main stem and tributaries of the Columbia River. One isolated fragment of the Columbia River segment includes Coeur d'Alene Lake, its tributaries in the drainage basin, and the Spokane River. Bull trout populations have been identified in Coeur d'Alene Lake and three tributaries in its sub-basin. There is no stream on the subject property and the mapped stream on adjacent property does not have a surface water connection to the Spokane River so the project will have No Effect on Bull Trout or proposed Bull Trout Critical Habitat. 4.2: Spalding's catchfly (Silene spaldingii), Federal Status: Threatened The survey for Spalding's silene was completed by walking pedestrian survey transects that were spaced to allow 100% visual coverage of the vegetative canopy. The distance between transect center lines was reduced as necessary to account for differences in terrain, vegetation density, and ground surface visibility. Silene spaldingii populations have been identified in the Palouse Grasslands of west-central Idaho and southeastern Washington; the Channeled Scablands in eastern Washington; the Blue Mountain Basins in northeastern Oregon; the Canyon Grasslands of the Snake River and its tributaries in Idaho. Within the Canyon Grasslands, Silene spaldingii is found at the lowest and highest elevations rangewide from 365 to 1,615 meters (1,200 to 5,300 feet) (ICDC 2007; summarized in USFWS 2007). Spalding's silene is found primarily in open grasslands and Idaho fescue/snowberry associations at elevations of 1900-3050 feet. Some of these sites occur in a mosaic of grassland and Ponderosa pine forest. Spalding's silene populations have been found on all aspects, although there seems to be a preference for slopes that face north. On drier sites, the species can be found on the bluebunch wheatgrass/Idaho fescue association. Some of the preferred conditions exist on this site. Each Silene spaldingii stem bears four to seven (up to 12) pairs of 2-3 inch long, lance-shaped leaves (Hitchcock et al., 1964 ). It has swollen nodes where the leaves attach to the stem. The plant is covered in dense sticky hairs that frequently trap dust and insects. Flowers have a tubular calyx approximately 0.6 inches long; the pale white petals extend slightly beyond the sepals. Flowers bloom from mid-July through August and sometimes into September. BSW investigated the site in late May but revisited the site on 10 July 2022 because the timing of the May site investigation occurred before the plant species would be flowering. The project biologist is a qualified botanist, is familiar with the species, and has observed it at other locations. Silene spaldingii overlaps in range and is somewhat similar in appearance with several other species in the genus, however, no species in that genus were at the project location so confusion of species was not an issue. The project biologist conducted a uniform grid search pattern covering each project area. No populations of Spalding's silene were identified in the Project Area during the field investigations. The project will have NO EFFECT on Spalding's Silene and will not result in the destruction or adverse modification of potential, designated or proposed Spalding's silene Critical Habitat. 11 4.3: Monarch Butterfly (Danaus plexippus) During the summer, Monarch butterflies mate and lay eggs several times until September when the final generation must migrate south to avoid lethal winter conditions in the Spokane area. Due to habitat destruction, fewer Monarchs return each year to their summer range in the Spokane vicinity. Monarch reproduction relies entirely on the milkweed plant. Female monarchs lay their eggs on the underside of milkweed leaves. Monarch caterpillars feed exclusively on milkweed and cannot feed on any other plant. The 2022 plant survey confirmed that no milkweed or potential Monarch habitat occurs in the vicinity of the Project Area. The project will have NO EFFECT on the Monarch butterfly and will not result in the destruction or adverse modification of potential, designated or proposed Monarch butterfly Critical Habitat. 4.4: Yellow-billed Cuckoo (Coccyzus americanus), Federal Status: Threatened The yellow-billed cuckoo was formerly a very rare summer visitor to western Washington, especially in the Puget Sound area [Roberson 1980]. Jewitt et al. (1953) described the former breeding range in Washington as ranging north to Bellingham, east to Ellensburg, south to Vancouver, and west to Grays Harbor. There are only two published records of yellow-billed cuckoo in eastern Washington. Yellowbilled cuckoos were detected on July 21, 1956, 20 miles north of Grand Coulee Darn in Okanogan County [Weber and Larrison 1977] and in June 1978 at George, Grant County [Roberson 1980]. The investigation for the Yell ow-billed cuckoo focused on specific habitat requirements of that species. Cuckoos prefer to nest in areas with at least 10 hectares (ha) (25 acres) of contiguous riparian woodland [Laymon 1998]. The typical patch size is 20 ha (50 acres) or greater, and the likelihood of occupancy increases dramatically with increasing patch size, but they have been found breeding in patch sizes as small as 4 ha (10 acres) along the Colorado River in southern California [Johnson, Matthew J., 2007]. Yellow-billed cuckoo's nest in undisturbed stands of cottonwood/willow galleries greater than 10 acres in total area and greater than 100 meters wide along waterways. The project area does not contain, and is not close to, adequate habitat patches for that species. The yellow-billed cuckoo is known not to utilize any habitat with characteristics of those found on or adjacent to this project. This project will not impact yellow-billed cuckoo populations or habitat components. There is no suitable habitat for the yellow billed cuckoo in the vicinity of this project. The project will have NO EFFECT on yellow-billed cuckoo or any designated or proposed critical habitat for that species because the species was not observed, there is no suitable habitat present, and there i:> no po:>:>ibility of effect:> to the :>pccic::i or habitat::i from the project. 5.0 WDF&W Priority Habitat and Species Assessment (Appendix 2) 5.1 White-tailed Deer (Odocoileus virginianus) Presence and Habitat: Common white-tailed deer habitat characteristics on the site include mixed species woodlands in multiple successional stages, two types of edge habitat, high availability of cover, presence of seasonal and permanent water nearby, low elevation, short, diversified slopes, and high quantity and quality of browse. White-tailed deer browse that is abundant on the site includes common snowberry, rose species, Oregon grape, kinnikinnik, and ceanothus. 12 Winter Range: Winter ranges are generally occupied from early December through late March, depending on weather conditions and food availability. Winter range is the most critical component of landscapes used by deer. The quality and quantity of available winter range are the primary limiting factors for white-tailed deer populations in Washington. Critical areas of closed-canopy (stands of at least 11 min height with overstory cover of at least 70%) that provide snow intercept are limited on the subject property. Deer activity on the site is also limited by the small size of the property, surrounding residential development, and because there is no water on the site. However, the site has some winter range characteristics including low elevation, deciduous and coniferous tree stands, and an abundant browse supply so the site is currently included as part of the home range for a small group of deer. Spring/Summer/Fall Range: The site provides classic spring, summer, and fall range characteristics for white- tailed deer including sloping meadows dominated by grasses, low elevation, and high quantity and quality browse (including ceanothus, rose, and common snowberry ), escape and thermal cover, natural travel corridors, and a small, forested area with some diversity of forest successional stages. The limiting factors for white-tailed deer utilization of the site are lack of on-site water and the relatively small, forested patch for cover. Three White-tailed deer were observed on the site on May 30, 2022. The presence of browsed shrubs, pellet piles, and a heavily used trail system, the identification of bed sites, and a deer skeleton confirm the site is part of the home range of a small number of white-tailed deer. 5.2 Elk ( Cervus elaphus) Presence and Habitat: Elk prefer grazing but also browse on trees and shrubs, depending on availability and nutrient content. The site provides food for elk but given the proximity and density of existing residential development and high road density, the site is unsuitable for elk. Elk may have historically wandered through the subject property, but under current conditions it is very unlikely. The unpeopled acres of the Dishman Hills and Iller Creek Conservation Areas on the north, west and south would be highly preferred elk travel routes. No sign of elk was observed on the subject property. BSW concludes that the Ponderosa property does not offer the seclusion required by elk, but the wooded draw on adjacent property to the west could serve as a travel corridor in the unlikely event that elk wander into the project area. The project will have no effect on elk or elk habitat. 5.3 Gray wolf (Canis lupus) Endangered Gray wolves occupy a wide spectrum of remote habitats that contain an adequate year-round prey base of ungulates, alternative prey, secluded denning and rendezvous sites, and isolation from human activity. No known populations or individual wolves are known to utilize or depend on the subject property as an important component of their home range. No scat, tracks, denning, or potential rendezvous sites were identified on the site. The surrounding residential development, the presence of primary and secondary roads, relative scarcity of prey species, and the absence of rendezvous and denning sites make the likelihood of adverse impact to the gray wolf very low. 13 It is possible that the gray wolf could wander through the site in search of prey, but due to lack of seclusion, wolves would not utilize the site for denning or rearing young. Dispersion of wolves could occur if they were traveling through the site when heavy equipment was operating during project construction. Traffic on adjacent roads and human activity near the site would probably deter wolves from coming near the site during the daytime when project construction activity would be under way. Once construction is complete, human disturbance associated with the residential area would discourage wolf activity. Unpeopled open space outside the project area in the Iller Creek and Dishman Hills Conservation Areas provides adequate habitat for wolves to move if they were disturbed while passing through the vicinity. The project will have no effect on wolves. 5.4 Shrub/Steppe Habitat WDF&W used the boundary of this 16.95 acre tax parcel to define a shrub/steppe habitat polygon on the PHS map. WDF&W defines Shrub-Steppe as a "nonforested vegetation type consisting of one or more layers of perennial bunchgrasses and a conspicuous but discontinuous layer of shrubs." Sagebrush is usually a dominant or co-dominant shrubsteppe species, but the species snowberry (Symphoricarpos albus) and rose (Rosa spp.) that occur on the subject property are often present in more meadowlike expressions of the shrub-steppe habitat type. The subject property has a high quality, healthy, mature, and diverse shrub canopy. The grass species Idaho fescue (Festuca idahoensis), Bluebunch wheatgrass (Pseudoroegneria spicata), and Sandberg bluegrass (Poa secunda), that are present on the subject property also occur in shrubsteppe habitat. However, there is no sagebrush on the site and the bunchgrasses identified on this site also occur in wetter locations and forested habitat types throughout the northwest as do snowberry and rose species. The subject property has an open canopy Ponderosa pine overstory because it receives more precipitation than areas defined as shrubsteppe habitat. The tree canopy also includes a patch of 60-70 aspens in the 3-10 dbh class with a snowberry and Oregon grape understory. The site has large patches of hawthorn shrubs with Oregon grape, snowberry, and rose on the perimeters. Aspens and hawthorns are found in landscape positions with greater precipitation and higher soil moisture holding capacity than occurs in steppe habitat. WDF&W defines Shrub-Steppe habitat as containing various habitat features, including diverse topography, riparian areas, and canyons. This small fragment of habitat does not have a variety of habitat features or habitat diversity. This landscape position is 100% upland in character, and the site has a nice upland shrub canopy, but it is not shrubsteppe habitat as defined by the WDF&W guidance used to describe and identify that habitat type. 5.5 Investigation of Other Wildlife Presence: Several wildlife species utilize the open Ponderosa pine woodlands and grassland/mixed shrub plant communities present at the project area. Systematic searches were conducted during the early morning and evening hours for mammals, raptors, and songbirds in 2004 and 2022. All observations were recorded, and overall wildlife habitat quality was assessed. Besides deer, no protected species were observed on the site. 14 Table 3: Animal Species (or sign) Observed in 2004 and/or 2022 Common Name Scientific Name Mammals: coyote Canis latrans Birds: white-tailed deer Odocoileus virginianus vole Microtus spp. yellow-pine chipmunk Eutamias amoenus black-billed magpie black-capped chickadee mourning dove American robin pygmy nuthatch California quail chipping sparrow American goldfinch house sparrow ring-necked pheasant American crow white-breasted nuthatch 5.6 Investigation of Other Critical Areas (Appendix 4) The Marble soil series mapped by the NRCS Web Soil Survey are loamy sand in the upper 8 inches underlain by sand to bedrock at 80 inches. The soils are well-drained. The site is described by FIRMette as an Area of Minimal Flood Hazard. There are no mapped geohazard areas on the site. 6.0 HABITAT MANAGEMENT PLAN The following Habitat Management Plan elements will be included in the Declaration of Protective Covenants. 1) Ponderosa Ridge East Will Form a Homeowners Association. The Declaration of Protective Covenants of the homeowner' s association will include the provisions for wildlife habitat protection described in this HMP. 2) Retain native vegetation on the lots. To the extent allowed by fire codes, homeowners are encouraged retain native vegetation including the open canopy forested component and understory shrub cover habitat to maximize food, thermal protection, hiding cover, nesting, and brooding cover for resident birds and mammals. Resource availability, specifically food and nest opportunities, are determining factors of the size and species richness of the bird community. Impacts on relative density, species richness, breeding, habitat, seasonal range dynamics and movement corridors will occur in proportion to habitat loss from the project. Homeowners are encouraged to landscape yards to provide multiple canopy levels for birds. 3) Minimize site disturbance beyond the manicured yard. Homeowners are encouraged to build comfortable, nicely manicured yards but to minimize site disturbance beyond the manicured yard. Minimize the removal of native vegetation beyond the manicured yard to maximize the quantity and quality of wildlife habitat. Homeowners are encouraged to enhance their properties with native vegetation from the species list provided below. 15 4) Homeowners shall manage noxious weeds as mandated by RCW 17.10, Spokane County, and The City of Spokane Valley. Weed control along roads and in common areas shall be rigorously managed by the homeowner's association. Noxious weeds will explode along new roads, open space tracts, and on homesites as soon as the soils are disturbed. HOA funds must be allocated for annual weed monitoring and control. Weed control measures shall be implemented in ways that do not adversely impact native vegetation. Homeowners shall manage noxious weeds on individual parcels as mandated by RCW 17.10, The City of Spokane Valley, and Spokane County. 5) Residents shall restrain free-ranging pets. Scavenging and predation on eggs and nestlings by rabbits, squirrels, mice, coyotes, opossums, raccoons, and skunks contribute to the steady annual attrition rate of birds. However, predation by domesticated dogs and cats has a devastating effect on resident bird populations. It is estimated that domesticated cats in North America kill 4 million songbirds everyday. Residents shall not allow pets to roam :freely to avoid impacts to the resident bird community. City/County Ordinances shall be strictly interpreted with respect to specific language prohibiting livestock and the restraint of pets. 6) Disturbed areas shall be reseeded with native grasses. Any disturbed soils in dedicated open space tracts shall be re-seeded with native grasses where maintenance is not required. This will prevent soil erosion and noxious weed invasion when earth-moving activities are completed. A mixture of native grasses will be selected to maintain the ecological integrity of the site. Once replanted, these areas should be left in a natural condition to provide food, cover, and refuge for wildlife. 7) Landscape to avoid human/animal conflicts. Human/animal conflicts may be reduced by thoughtful landscaping practices. Preserve existing vegetation and landscape with native plant materials with the expectation that deer will eat your shrubs. Or landscape with plants that deer do not find palatable. The Spokane County Conservation District can provide a list of unpalatable species. District extension agents can also provide homeowners with a list of native trees and shrubs offered for sale by that agency each spring.

The replication of structural complexity, vertical stratification, and microhabitat diversity should be emphasized in the planting design. Shrubs should be planted with the goal of enhancing wildlife habitat. The vegetation should be planted in patches, have curving edges, and not be planted in a uniform manner. Rationale Structural complexity refers to the arrangement and degree of interspersion of plant community types throughout the system. Complex structural patterns (such as variable patch size, curving edges, and high degree of interspersion between species) increase the value of a system for wildlife. Good wildlife habitat consists of open areas interspersed with clusters of vegetation, several horizontal layers, and a variable structural pattern. Vertical stratification describes a community with good structural diversity and several horizontal layers (logs, woody debris, forbs, shrubs, and trees). Woody debris provides travel routes, perch sites, cover, and thermal refuge for a variety of small mammals and ground nesting birds. Microhabitat diversity refers to variety in microhabitat types. Examples of microhabitat types include herbaceous cover and shrubs that provide food, habitat, and substrate for a variety of plants and animals. 7.0 CONCLUSIONS The best way to preserve wildlife species density and species richness is to minimize human intrusion into their domain. Animal species have varying degrees of tolerance to human activity. Some birds build their nests on human constructions, communicate over traffic, eat our garbage, and move freely among the cars on our streets. On the other extreme, some species require hundreds of square miles of unpeopled land for their homes. 17 The Growth Management Act (GMA) suggests that we stop urban sprawl and preserve areas with a distinct rural character. The GMA says that by increasing human density within a delineated boundary we will preserve wildlife habitat outside of the boundary. In writing Habitat Management Plans, biologist's endeavor to find ways to accommodate increased housing density within the urban growth boundaries while maintaining green space and wildlife corridors in the same area. These objectives are not always compatible and must be viewed in the larger context of the GMA goals of preserving rural character and wildlife habitat outside the growth boundaries. These GMA goals reflect the fact that most species are not well adapted to life in an urban environment. This development sits on the edge of the Urban Growth Boundary. Every new development results in a loss of wildlife habitat. Little can be done to compensate for the loss of habitat caused by an increasing human population. The best we can do is what we are doing, relegating growth to areas within the urban growth boundaries and building at high density. As the population of Spokane County continues to grow, there is no alternative to maximizing density in designated growth areas to protect undisturbed wildlands outside of the growth boundary. People and animals must both adjust to increasing density inside the urban growth boundary. The 2004 Preliminary Plan and Habitat Management Plan was designed to accommodate wildlife travel through the west part of the development as dictated by natural topography and habitat features. No travel corridors were proposed in the Ponderosa Ridge East part of the site because existing residential development on the south side of 44th Avenue, west side of Farr Road, and north side of Holman Road denied wildlife access to the site from the north, east, and south sides of the property respectively. The Ponderosa Ridge II development will block wildlife access to the Ponderosa Ridge East site from the west. The Ponderosa East site will be surrounded by residential development. White-tailed deer live within a well-defined home range with an area of about one square mile. The proposed development will eliminate part of the home range of White-tailed deer living in the vicinity. Resident deer will have to adjust their home range boundary to rely more on adjacent forested land to the south and west that is outside the Urban Growth Boundary. The remaining fragments of habitat within the development will still be accessible by birds. 18 8.0: LIMITATIONS Within the limitations of scope, schedule, and budget, BSW services have been executed in accordance with best available science and generally accepted professional practices for the conditions at the time the work was performed.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7( c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means vvhereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(l) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological 06/02/2022 evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. 2 If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act (ESA), there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BG EPA) to protect native birds from project-related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (SO C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php. The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-to- birds. php. In addition to MBTA and BG EPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/ executive-orders/e0-13186.php. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office. 06/02/2022 Official Species List This list is provided pursuant to Section 7 of the Endangered Species Act, and fulfills the requirement for Federal agencies to "request of the Secretary of the Interior information whether any species which is listed or proposed to be listed may be present in the area of a proposed action".
