Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

50.00 Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

FOCUSED BIOLOGICAL SURVEYS OF NOBLE CREEK VISTAS PROJECT
CITY OF BEAUMONT, RIVERSIDE COUNTY, CALIFORNIA
SUMMARY
Focused surveys for rare plants and the burrowing owl were conducted at the 332 -acre Noble Creek Vistas project site located in the City of Beaumont, Riverside County, California. The project site was surveyed on Monday, April 16, 2001. Neither burrowing owls nor rare plants were detected onsite.
INTRODUCTION
Harmsworth Associates was retained by Applied Planning, Inc. to conduct a biological assessment of the Noble Creek Vistas Site. Focused surveys for rare plants and the burrowing owl were conducted at the 332 -acre Noble Creek Vistas located in the City of Beaumont, Riverside County, California.
The purpose of the biological assessment was three -fold: (1) to determine presence/absence of rare plants onsite, (2) to determine presence/absence of the burrowing owl, and (3) verify, update and supplement information provided in previous biological resources surveys/reports prepared for the project site and vicinity. Previous surveys/reports considered in this regard included: the Wildlife/Vegetation Section of the Noble Creek Specific Plan Draft Environmental Impact Report (DER', dated June 5, 1998). The DEIR provided information from surveys in 1998 (VHBC 1998), and from a Biological Assessment conducted in 1992 (hereafter referred to as "BA") and a site check for Stephen's Kangaroo Rat in 1991.
SETTING
The project site is located at the foothills of the San Bernardino Mountains, north of the City of Beaumont, southwest of Cherry Valley (Please refer to Figure 1). The irregularly - shaped project area, is bounded by Brookside Avenue on the north; Beaumont Avenue on the east; 14th Street/Oak Valley parkway to the south; Noble Creek Park to the southwest, and the Oak Valley Planned Residential Community to the west. (Please refer to Figure 2). From its northeasterly corner at the intersection of Brookside Avenue and Beaumont Avenue, the project area slopes gently southwesterly. Elevations within the project area range from 2,800 feet above mean sea level (MSL) in the northeast to 2,600 feet MSL in the southwest.
The majority of the project site has historically been used for dry -land farming and cattle grazing. However there is no current, nor has there been any recent productive agricultural use of the project area. At present, the proposed Specific Plan area is HARMSWORTH ASSOCIATES 1

predominantly vacant and unimproved, although site preparation has been initiated for a Middle School facility to be constructed in the easterly portion of the project site, northwesterly of the proposed intersection of Cougar Way and Beaumont Avenue. One residential home with scattered auxiliary buildings also exists within the project area.
The unlined Noble Creek storm channel (a blue -line drainage as depicted on the U.S.
Geological Survey (USGS) topographic map Beaumont, California [dated 1996]) transects the project site in a northeast to southwest direction. Within the Noble Creek channel area, the County Parks and Recreation Department is currently conducting limited sand and gravel mining/reclamation for its use in development of recreation proj ects.
Another notable feature within the project area is an approximately 200 foot wide Southern California Edison utility easement. With overhead high -voltage power lines in place, this easement crosses the southern portion of the site in an east -west direction, approximately 1,000 feet north of 14th Street.
Northerly of the project area is the Unincorporated Community of Cherry Valley.
North/northwesterly of the project site land uses are characterized by scattered single- family residences and vacant, unimproved properties. Additional uses in this area include a mobile home park and a County maintenance yard located to the north/northwest of the project site.
Adjacent and abutting properties to the east, south and west of the project site lie within the City of Beaumont. Easterly of the project site, across Beaumont Avenue, are mix of uses including vacant, unimproved properties; single and multifamily residential development; neighborhood commercial uses; and the City Sports Park. Southerly of the project site, across 14th Street, are vacant properties and scattered single-family residences. Noble Creek Park constitutes the southwesterly boundary of the project area.
To the west of the project, on -going (as of April 2001) construction of the Oak Valley Planned Residential Community is occurring.
METHODS
Records of the California Natural Diversity Database (CNDDB, 2001) and California Native Plant Society's Inventory of Rare and Endangered Vascular Plants of California (2001) were reviewed regarding the potential occurrence of any federal or state listed or proposed endangered or threatened species, candidate species, or otherwise sensitive species or habitat within or in close proximity of the project site. In addition, the Riverside County Checklist for Species or Environmental Issues of Concern was reviewed (Appendix C).

Biological Surveys 2001
Botanical Survey
Based on the results of the CNDDB and CNPS archival search, several sensitive plant species were identified as potentially occurring onsite, including Calochortus plummerae (Plummer's mariposa lily), Caulanthus simulans (Payson's jewel flower), Astragalus jaegeri var. pachypus (thick -podded rattleweed), Hemizonia laevis (smooth tarweed), Chorizanthe parryi (Parry's spineflower), Quercus engelmannii (Engelmann Oak)„ Atriplex coronata var. notation (San Jacinto Valley saltbush), Dodecahema leptoceras (slender horned spineflower), and Eriastrum densiflorum ssp. sanctorum (Santa Ana woollystar). Focused surveys for these target species were conducted in all suitable habitats.
The entire site was surveyed on foot. Focused botanical surveys were concentrated within Noble Creek and the adjacent terraces where native vegetation persisted, and where rare plant species were most likely to occur. Unknown plant species were collected and identified. Questionable taxa identification were confirmed by Mr. Andrew Sanders (curator for the University of California, Riverside Herbarium).
Burrowing Owl Survey
The spring survey for the burrowing owl (Speotyto cunicularia) followed the CDFG survey protocol for the species (CDFG, September 1995), as follows: three biologists conducted the survey by walking survey transects (no more than 30 meters apart) within suitable habitat on the entire project site. The survey was conducted from one hour before to two hours after sunrise. Careful inspections of all burrows and man-made structures (debris piles) were conducted to determine if the burrows were occupied by burrowing owls. Furthermore, burrow entrances were inspected for presence of birds, molted feathers, cast pellets, prey remains, eggshell fragments and excrement. Each biologist was familiar with the vocalization of the burrowing owl.
RESULTS AND DISCUSSION
On Monday, April 16, 2001, biologists of Harmsworth Associates (HWA) [Mr. Adrian Wolf, Mr. Paul Galvin and Mr. Brian Karpman] examined the property for the burrowing owl and rare plants. All plant and wildlife species detected during the surveys were noted and appear in Appendix A and B.
Vegetation and Botanical Resources
Habitat types observed onsite were generally consistent with the descriptions presented in 1998 DEIR. The vegetation was remapped since the site conditions had changed slightly from the conditions described and mapped in 1992 (PSBS 1992). Six distinct vegetation categories were noted during the current biological study: disturbed annual/ruderal grassland, disturbed alluvial fan scrub, disturbed Riversidian sage scrub, disturbed sycamore woodland, ornamental landscaping and disturbed (Table 1, Figure 3).

* Note: acreage of ornamental landscaping included within annual grassland acreage Disturbed Annual/Ruderal Grassland
The majority of the gentle sloping broad historic floodplain east and west of Noble Creek consisted of non-native annual grasslands dominated by a variety of Mediterranean non- native grasses and forbs, including Bromus diandrus (ripgut brome), Bromus madritensis ssp. rubens (red-brome), Bromus tectorum (cheat grass) and Erodium cicutarium (red - stemmed filaree). Other non-native species detected within this community included Hirschfeldia incana (shortpod mustard), Pectocarya linearis var. ferocula (pectocarya) and Poa annua (annual bluegrass). Native shrubs, including Lepidospartum squamatum (scalebroom) and native herbs such as Cryptantha intermedia (common popcorn flower) and Amsinckia menzeisii var. intermedia (fiddleneck), Croton californicum (California croton), Eriogonum fasciculatum (California buckwheat) and Heterotheca grandora (telegraph weed) were scattered throughout the annual grasslands. The grassland was heavily disturbed as a result of decades of dryland farming and cattle grazing.
Disturbed alluvial fan scrub
Noble Creek extended south of Brookside Avenue through a culvert then continued south channelized between corrugated sheet pilings on both sides of the wash for approximately 1000 feet at which point the piling structures ended and the creek opened into a broad floodplain. Little vegetation remained in the channelized portion. In the broader plain, sparsely distributed shrubs included Lepidospartum squamatum (scalebroom), Eriogonum fasciculatum (California buckwheat), Baccharis salicifolius (mulefat), Lotus scoparius (deerweed) and Artemisia dracunculus (tarragon). Several other native and non-native herbaceous species were detected growing in the alluvium and banks, including Salvia columbariae (chia), Bromus tectorum (cheat grass), Cryptantha intermedia (popcorn flower), Penstemon spectabilis (showy penstemon) and Phacelia distans (common phacelia).
Disturbed Riversidian sage scrub
Riversidian sage scrub (RSS) dominated by Eriogonum fasciculatum occurred in two areas within the project site: 1) in the northwestern portion of Noble Creek outside of the gravel mining operations, east of the concrete lined Mountain View Storm Channel; and 2) in the southern portion of the site, where a prominent knoll feature provided steep HARMSWORTH ASSOCIATES 7

slopes that supported RSS, east of the Noble Creek Park, north of Fourteenth Street. The RSS onsite was heavily disturbed by cattle grazing and invasive exotic species, and little native understory persisted. Native species detected within the RSS community included Sambucus mexicana (Mexican elderberry), Artemisia californica (California sagebrush) and Ericameria palmeri ssp. pachylepis (grassland goldenbush). The composition of the understory within the RSS was similar to that of the adjacent non-native annual grasslands.
Disturbed sycamore woodland
To the west of Noble Creek, five mature Platanus racemosa (western sycamores) occurred on the historic upper floodplain terrace. The understory vegetation in the vicinity of the sycamore trees was comprised of non-native grassland species similar to the non-native annual grassland community, however, relics of historic woodland/scrub elements were widely scattered including Sambucus mexicana (Mexican elderberry), Lepidospartum squamatum (scalebroom), Opuntia littoralis (prickly pear cactus) and valley cholla (Opuntia parryi var. parryi).
Ornamental Landscaping and Plantings
Ornamental plantings of Cedrus deodar (Deodara Cedar) lined Beaumont Avenue extending from Fourteenth Street to Brookside Avenue. In the southern portion of the property, Olea europeae (Olive), an occasional Schinus molle (Peruvian pepper tree) and Eucalyptus sp. were noted.
Disturbed (gravel mining).
A sand and gravel mining operation was observed in the lower portion of Noble Creek, extending upstream from Noble Creek Park for approximately 1,000 feet. Gravel mining equipment was present onsite and no vegetation occurred within the vicinity.
Floristics
Floristic abundance onsite was low due to the highly disturbed nature of the site resulting from agricultural activities and cattle grazing. A total of 83 plants species (representing 29 families) were detected during the survey, including 52 native and 31 non-native species (Appendix B). The EA studies recorded 88 taxa (representing 33 families), however, the increased number of taxa recorded was likely as a result of the larger survey area which included several other vegetation types (oak trees etc.) north of Brookside Avenue and east of Beaumont Avenue which were not present onsite.
Sensitive Vegetation and Plants
Upland Riversidian sage scrub and Riversidian alluvial fan sage scrub are declining regionally and are thus considered rare plant communities by the Resource Agencies.
However, the two communities' onsite were highly degraded as a result of historical cattle grazing, agricultural activities and gravel mining operations.

Surveys for rare plants were concentrated in the natural vegetation communities including alluvial fan sage scrub and Riversidian sage scrub. The majority of the native understory herbs and forbs were in flower and were concentrated in areas within Noble Creek and in the shallow soils of the annual grasslands where non-native exotic species were precluded. No sensitive plant species were detected during the survey. Due to the highly disturbed nature and the poor quality of the native habitat types, no sensitive plant species are expected to occur within the project site.
Wildlife Survey
Burrowing Owl Survey
Surveys were initiated at 0530 in the southern portion of the project site. One biologist walked in the streambed, the other two walked flanked the streambed by walking along the upper banks of the creek. Several burrows made by fossorial mammals (presumably ground -squirrel) were noted in the banks along Noble Creek extending from the gravel mining operation to Brookside Avenue. In addition, several debris piles in the vicinity of the gravel mining operation were noted. Each burrow complex and debris pile was inspected for burrowing owl sign (pellets, excrement, etc). Surveys for owls were also conducted in the annual grasslands east and west of Noble Creek. In addition, the banks of the creek near the corner of Beaumont Avenue and Fourteenth Street (offsite) were surveyed.
Ground -squirrel burrow complexes were common within the project site primarily distributed along Noble Creek and east of Noble Creek within the annual grasslands north of the powerlines and adjacent Beaumont Avenue. The majority of these large burrow complexes were occupied by ground squirrels and neither burrowing owls (nor sign) were detected during the surveys.
The CDFG survey protocol for the burrowing owl recommends both spring and winter surveys for the species. Due to the presence of several burrow complexes onsite and adjacent suitable foraging habitat, winter surveys are recommended.
General Wildlife
Wildlife detected on the project site was typical of those found within open habitat types and grassland vegetation communities (Appendix A). For example, avian species typical of grassland habitats such as savannah sparrows (Passerculus sandwichensis), western meadowlark (Sturnella neglecta), mourning doves (Zenaida macroura), homed lark (Eremophila alpestris), lesser goldfinch (Carduelis psaltria), and lark sparrows (Chondestes grammacus) were common. Two raptor species were detected including the red-tailed hawk (Buteo jamaicensis) and American kestrel (Falco sparverius). On the western boundary of the project site, an active red-tailed hawk nest (with nestlings) was observed in one of the large sycamore trees.

Reptiles detected onsite included the side blotched lizard (Uta stansburiana), and western fence lizard (Sceloporus occidentalis).
Species typically associated with scrub communities were absent from the project site presumably due to the highly disturbed nature of the site. For example, wrentits (Chamaea fasciata), Bewick's wren (Thryomanes bewickii), California towhee (Pipilo crissalis), nor spotted towhee (Pipilo erythrophthalmus) were detected onsite which are commonly found in scrub habitats.
Sensitive Wildlife
The CNDDB identified several sensitive wildlife species with potential to occur onsite include Stephen's kangaroo rat (Dipodomys stephensii), San Diego horned lizard (Phrynosoma coronatum), and western spadefoot toad (Scaphiopus hammondii).
Three sensitive wildlife species, all "California Species of Concern Species" were detected onsite, namely the San Diego black -tailed jackrabbit (Lepus califbrnicus), horned lark (Eremophila alpestris) and western spadefoot toad (Scaphiopus hammondii).
Several jackrabbits and horned larks were flushed from the RSS and grasslands in the western portion of the project site. In the southern portion of the project site, east of Noble Creek Park, south of the SCE pole location on the prominent hill, an old pond feature occurred within the natural shallow drainage (Figure 2). Baccharis salicifolius (mulefat) and Eucalyptus surrounded the temporary pond wherein less than 20 spadefoot toad larvae (tadpoles) were detected. The adjacent RSS and uplands provide suitable foraging habitat for the adult spadefoots.
No other sensitive wildlife species were detected onsite.
A site assessment conducted for Stephen's Kangaroo Rat (Dipodomys stephensi) and San Bernardino Kangaroo rat (Dipodomys merriamiparvus) (Philippe Vergne, pers. comm.). identified suitable habitat on the property and recommended that trapping surveys be conducted to determine whether the species occurs onsite. Trapping is expected to be conducted in summer 2001.
Other Sensitive Environmental Issue of Concern
Other sensitive environmental issues concern the presence of Noble Creek (as indicated by the blueline stream on the USGS maps) and the temporary pond located in the southern portion of the project site. At this conceptual stage of the project, it is estimated that up to 13 acres of wetlands/jurisdictional and streambed areas waters (as defined by the U.S. Army Corps of Engineers' [Corps] ) and CDFG) may by affected by the proposed project. Consistent with final tract map design of the Specific Plan, a detailed wetland delineation will be required to determine the extent of the CDFG and U.S. Army Corps of Engineers' (Corps) jurisdictions onsite. If impacts occur to either CDFG and Corps jurisdictional areas, appropriate permits (CDFG Streambed Alteration Agreement, Corps 404, and State Regional Water Quality Control Board 401) will have to be obtained.

EXECUTIVE SUMMARY
Philippe Vergne was contracted by Applied Planning, Inc, to conduct a trapping survey for Stephens' kangaroo rat-SKR (Dipodomys stephensi) on the Noble Creek Vistas site. The trapping survey was required due to the presence on the property of suitable SKR habitat, and the presence of kangaroo rat sign.
Following is a report describing the results of a trapping survey and habitat assessment for Stephens' kangaroo rats on the above -described property. The report is a summary of trapping surveys of the site performed for five consecutive days from June 12-16, 2001 by Philippe Vergne, a certified SKR biologists (PRT-831207).
Based on the available information and site conditions, there was a low probability that SKR might occuron the proposed project site. Good quality habitat was present on portions of the property and significant concentrations of kangaroo rat burrows and scat suggested that SKR might be present in at least some of the grasslands on the property. A non protocol survey performed by Steve Montgomery on the site in 1981 confirmed the presence of the Dulzura kangaroo rat-DKR (Dipodomys simulans)(than PKR) on the property.
Through protocol trapping on the current survey it was possible to verify the absence of SKR inthose areas which initially exhibited potential habitat and k -rat sign. No SKR were captured during the trapping survey and therefore it is concluded that the site is not occupied by SKR.
Although out of the known distribution and range for the San Bernardino Kangaroo rat (Dipodomys meriani parvus) the noble creek channel which bisects the site was trapped since it contains suitable habitat for both SKR and SBKR. No SBKR were captured during the trapping survey.
PROJECT DESCRIPTION
The proposed development site occupies an estimated 332 acres between Brookside Avenue and 14 th Street, in an unincorporated area adjacent to the City of Beaumont, in Riverside County California (Figure 1). The property is located in sections 33 and 34, T2S, R1W, of the USGS 7.5" Beaumont Quadrangle. The project calls for the development single family homes, middle school, parks and open spaces.
METHODS
Stephens Kangaroo Rat
The Stephens' kangaroo rat is one of several kangaroo rat species in its range.
The Dulzura (Dipodomys simulans), the Pacific kangaroo rat (Dipodomys agilis) and the Stephens kangaroo rat (Dipodomys stephensi) occur in overlapping ranges in southern California.
The Stephens kangaroo rat (SKR) prefers open areas with sparse perennial cover (Lackey 1967, Bleich 1977, Thomas 1975). They occur in areas of loose soil where the soil depth is at least 0.5 meters (Price and Endo, 1989). SKR will also inhabit disturbed areas such as fallow fields by using the burrows of other rodents, including pocket gophers (Thomomys bottae) (Bleich 1977) and the Beechey ground squirrel (Spermophilus beecheyi) (O'Farrell 1989).
Like all kangaroo rats, the SKR is primarily a seed eater, feeding on the seeds of both annual and shrub species. It also feeds on green vegetation and insects when these are available. Being primarily a dry biome species, kangaroo rats obtain nearly all of their water from the food they eat, and can subsist indefinitely on water extracted from dry seeds. They forage in open ground and underneath shrubs.
Burrows are dug in loose soil.
Both the Dulzura and Pacific kangaroo rats are known to occasionally inhabit open grasslands more characteristic of SKR, while SKR are infrequently known to inhabit areas of denser vegetation.

Trapping is often the only definitive method of confirming the absence/presence, distribution, and abundance of SKR in areas where they are sympatric with other kangaroo rat species, or where trace sign is found.
The San Bernardino Kangaroo Rat
Both the Dulzura kangaroo rat and the Stephens kangaroo rat (Dipodomys stephensi) occur in areas occupied by the San Bernardino kangaroo rat, but these other two species have a wider habitat range. The habitat of the San Bernardino kangaroo rat is described as being confined to primary and secondary alluvial fan scrub habitats, with sandy soils deposited by fluvial (water) rather than aeolian (wind) processes.
Like all kangaroo rats, the San Bernardino kangaroo rat is primarily a seed eater, feeding on the seeds of both annual and shrub species. It also feeds on green vegetation and insects when these are available. Being primarily a desert species, the San Bernardino kangaroo rat obtains nearly all of its water from the food it eats, and can subsist indefinitely on water extracted from dry seeds. It forages in open ground and underneath shrubs. Burrows are dug in loose soil,usually near or beneath shrubs.
The San Bernardino kangaroo ratis one of three subspecies of the Merriam's kangaroo rat. The Merriam's kangaroo rat is a widespread species that can be found from the inland valleys to the deserts. The subspecies known as the San Bernardino kangaroo, however, is confined to inland valley scrub communities, and more particularly, to scrub communities occurring along rivers, streams and drainages.
Most of these drainages have been historically altered as a result of flood control efforts and the resulting increased use of river resources, including mining, off -road vehicle use and road and housing development. This increased use of river resources has resulted in a reduction in both the amount and quality of habitat available for the San Bernardino kangaroo rat. The past habitat losses and potential future losses prompted the recent emergency listing of the San Bernardino kangaroo rat as an endangered species (U.S. Fish and Wildlife Service, 1998a).
Habitat Evaluation Surveys
We conducted a preliminary phase one walkover survey of the site to determine the habitat types on site and identify potential habitat for the kangaroo rat. Trace and low Kangaroo rat sign densities were observed in some of the disturbed annual grasslands, within the drainage area and in most of the sparse scrub habitat on the site.
As part of the habitat assessment, we conducted a focused evaluation of the on site habitats in order to identify the most suitable trap sites. We also recorded the various plant communities and condition of the habitats on site. Based on the field survey findings, we selected 6 areas for trapping (Figure Two).
Trapping Surveys
Trapping was conducted according to United States Fish and Wildlife Service-USFWS protocols established for the SKR. The protocol calls for five nights of trapping, conducted when the animal is active above -ground at night and preferably during a new moon phase The trapping sessions lasted from June 12 -16, 2001.
We placed the traps in suitable habitat areas on the project, concentrating on locating traps in areas containing soils and vegetation suitable for the SKR. Dirt trails and open areas with minimaldisturbance were also targeted. Each trap was baited with a mixture of bird seed and rolled oats, placed at the back of the traps. The traps we reopened at dusk each night and inspected at night and dawn each morning. A11 animals were identified and released at the point of capture.
Notes were recorded on the habitats, soils and other relevant characteristics where the traps were placed. We also noted the weather conditions at the time of the trapping surveys.

RESULTS
Topography
Topography on the grassland areas of the site is primarily gently sloping terrain, with elevations ranging from 2580 to 2660 feet.
Soils
The soils on site range from fine to coarse sandy loams of the Hanford, Ramona, and Gorgonio type. The soil encountered on site are suitable for use by kangaroo rats.
Vegetation
Three major vegetation communities are present on the site: disturbed annual grasslands, sage scrub, and alluvial fan scrub.
The disturbed annual grasslands are dominated by filaree (Erodium cicutarium), bromes (Bromus diandrus, B. madritensis, B. mollis), wild oats (Avena barbata),popcorn flower (Cryptantha intermedia), fiddleneck (Amsinckia tessellata), and shortpod mustard (Hirschfeldia incana),Invasives such as annual sunflower (Helianthus annuus), telegraph weed (Heterotheca grandiflora) and ragweed (Ambrosia psilostachya) are found adjacent to the washes.
The open and disturbed sage scrub community is found in remnant locations within the grassland areas, and at the edge of the drainages. Dominant plant species in the sage scrub community are flat -top buckwheat (Eriogonum fasciculatum), horehound (Marrubium vulgare), California sagebrush (Artemesia californica. Shrub cover was low (<30%) with an undercover of bromes and filaree.
Also present on site is sparse and disturbed alluvial fan scrub along the main drainage and adjacent benches.The alluvial fan scrub at the time of the survey was limited to scattered individuals of flat-topped buckwheat (Eriogonum fasciculatum), scale broom (Lessingia filaginifolia), California sagebrush (Artemisia californica), and and mulefat (Baccharis salicifolia).
Disturbances on the site include power easements, grazing, disking and dry crop farming, a quarry, dirt roads, storm channels, old structures, grading, and limited off road activity.
Weather Conditions
Temperatures were in the low seventies throughout the survey. The moon was half and increasing.
Trapping Results
A total of 1,000 collapsible Sherman live -traps was set out over the 5 -night effort at the 6 trapping localities exhibiting potential SKR habitat. Traps were set in the portions of the grasslands, sparse sage scrub and open alluvial fan scrub exhibiting the open (sparsely vegetated) habitat conditions typically preferred by SKR
A total of 32 captures of the non -endangered Dulzura kangaroo rat (Dipodomys simulans) was recorded at the various grassland trap locations. Since captured animals were not individually marked, it is certain that this total represents fewer than 32 different individuals. Two sensitive species, the northwestern San Diego pocket mouse(Chaetodipus fallax fallax)and the Los Angeles pocket mouse (Perognathus longimembris brevinasus) were captured. The ubiquitous deer mouse (Peromyscus maniculatus)and the cactus mouse (Peromyscus eremicus) were also captured (Table One).
Trapping success was low over the entire trapping period. Table 1 provides information on the species trapped per trap area.

A description of the trapping site ,follows:
Site 1
Site 1 is comprised mostly of disturbed annual grassland,remnant sage scrub and sandy wash. Soils are coarse sands and sandy loams. The plant cover is less than 20% percent (Picture 1).
Site 2
Site 2 is comprised mostly of disturbed annual grasslands. Portions of the site contain remnant sage scrub and alluvial fan scrub. Vegetation cover is less than 30%. Soils are sandy (Picture 2).
Site 3
Site 3 is comprised mostly of disturbed annual grasslands.Vegetation cover varies from 20 to 30 percent . Soils are sandy (Picture 3).
Site 4
Site 4 is comprised mostly of disturbed annual grasslands. The Noble Creek drainage bisects the site.Portions of the site contain remnant sage scrub and alluvial fan scrub. Cover is less than 30 percent. Soils are sandy(Picture 4).
Site 5
Site 5 is dominated by disturbed annual grasslands with sage scrub remnants. Soils are sandy (Picture 5).
Site 6
Site 6 is comprised mostly of disturbed annual grasslands. Cover is less than 30 percent. Soils are sandy (Picture 6).
CONCLUSIONS
Based on the available information and site conditions, there was a low probability that the SKR might occur on the project site. Although outside of the known distribution area there was also a low probability, based on habitat, that SBKR might occur on the site.
No SKR were caught during the trapping studies, and therefore this species is not present on the proposed project site. No SBKR were captured and their absence from the project site and the general area continues to be confirmed.
Lands immediately surrounding the property vary in their suitability for potential occupation by SKR. The properties to the west, north and south have similar habitat to that found on site, and have low potential for occupancy. Lands to the east have been more impacted by dry crop farming and development and have very limited potential for occupancy.

Subject: Noble Creek Vistas Specific Plan Traffic Study Response to Comments
Dear Mr. Geller:
Comment #1
Cherry Valley complains that the EIR concluded that traffic impacts would not be significant despite degradation of the level of service ("LOS") at certain County intersections from the County's acceptable level of service ("C") to the City's acceptable level of service ("D").
Response #1
The County of Riverside General Plan level of service criteria is "C" or better at study area intersections located more than a mile away from a freeway interchange. A peak hour analysis has been conducted for the intersection of Beaumont Avenue and Cherry Valley Boulevard for General Plan buildout conditions. The attached service level table and worksheets indicate that the following improvements (beyond existing conditions) would be required to allow this intersection to operate at an acceptable service level ("C" or better):
• Northbound Approach
Construct an additional left turn Zane
- Construct an additional through lane
Construct a right turn lane
• Southbound Approach
- Construct an additional left turn lane
- Construct an additional through Zane

• Eastbound Approach
- Construct an additional through Zane
- Construct a right turn lane
• Southbound Approach
- Construct an additional left turn Zane
- Construct an additional through lane
- Construct a right turn lane
It is important to note that these long range future improvements are needed with or without the project, as indicated in Table 1. If you have any questions regarding this analysis, please do not hesitate to call at (949) 660-1994.

4 When a right turn is designated, the lane can either be striped or unstriped. To function as a right tum lane there must be sufficient width for right turning vehicles to travel outside the through lanes.
L = Left; T = Through; R = Right; » = Free Right Tum; 2 = Lane Improvement Delay and level of service calculated using the following analysis software: Traffix, Version 7.1.0607 (1999). Per the 1997 Highway Capacity Manaul, overall average intersection delay and level of service are shown for intersections with traffic signal or all way stop control. For intersections with cross street stop control, the delay and level of service for the worst individual movement (or movements sharing a single lane) are shown.
TS = Traffic Signal
— = Delay High Intersection Unstable, Level of Serivce = "F".

Currently the intersections of Beaumont Avenue at the I-10 Freeway WB Ramps - 5th Street and Beaumont Avenue at the I-10 Freeway EB Ramps - 4th Street are operating at Level of Service "E" during the PM peak hour.
2. Development Description
The approximately 332.3 acre project site is proposed for single-family detached residential and junior high school uses.
3. Principal Findings
a. Required Level of Service: "D"
b. Level of Service With Proposed Development: For Buildout traffic conditions with the project, the following study area intersections are projected to operate at Level of Service "F" during the peak hours, without improvements:
Beaumont Avenue (NS) at:
• Cherry Valley Boulevard (EW)
• 14th Street (EW)
• I-10 Freeway WB Ramps - 5th Street (EW)
• I-10 Freeway EB Ramps — 4th Street (EW)
c. Level of Service With Proposed Development and With Additional Improvements: For Buildout traffic conditions with the project, study area intersections are projected to operate at Level of Service "D" or better during the peak hours with the following off -site improvements:
1-3
Beaumont Avenue (NS) at:
• Cherry Valley Boulevard (EW)
Construct a second through lane for all
approaches
Provide an additional southbound left turn Zane
Provide an eastbound right turn Zane
• 14th Street (EW) .
- Construct a second through westbound through
lane
Provide a second left turn lane for the
northbound, southbound and westbound
approaches
Provide a right turn lane for the northbound,
southbound, and eastbound approaches
• 1-10 Freeway WB Ramps (EW)
Restrict 5th Street access to/from Beaumont
Avenue
Construct a loop ramp in the northeast quadrant
to provide westbound access onto the I-10
Freeway. This improvement will eliminate the
northbound left turn lane at this location
Provide a southbound right turn Zane
Provide a shared westbound lane for left and
right tums
• I-10 Freeway EB Ramps (EW)
Restrict 4th Street access to/from Beaumont
Avenue at this location
Construct additional northbound through and
right tum lanes
1-4
Construct a second southbound left turn lane
and a second eastbound left turn lane
Provide an eastbound free right turn lane
4. Conclusions
The proposed site is projected to generate a total of approximately 10,395 trip -ends per day with 1,091 vehicles per hour during the AM peak hour and 1,102 vehicles per hour during the PM peak hour.
The proposed project will have access to Beaumont Avenue, Brookside Avenue, Cougar Way and 14th Street.
The project's fair share contribution to the study area are presented in Table 5-5. The PM peak hour (typically the period when the traffic volumes are the greatest) has been used for the calculations. As indicated in Table 5-5, the project traffic contributes approximately two percent of the cumulative traffic growth at the Beaumont Avenue/I-10 interchange.
5. Recommendations
Construct Beaumont Avenue south of Brookside Avenue to the south project boundary at its ultimate half -section width as a Major highway in conjunction with development.
Construct Brookside Avenue from the west project boundary to Beaumont Avenue at its ultimate half -section width as a Secondary highway.
Construct Cougar Way from Beaumont Avenue to 14th Street at its ultimate cross-section width as a Collector in conjunction with development. 1-5
Construct 14th Street from Cougar Way to the east project boundary at its ultimate half -section width as an Arterial highway in conjunction with development.
Site -specific circulation recommendations are depicted on Exhibit 6-A.
Precise access locations shall be determined at the plot plan or tentative tract map level, subject to approval by the City of Beaumont.
The project should contribute towards a citywide roadway improvement program, as a result of infrastructure development fees for the City of Beaumont.
Sight distance at each project entrance should be reviewed with respect to standard Caltrans/City of Beaumont sight distance standards at the time of preparation of final grading, landscape and street improvement plans.
Participate in the phased construction of traffic signals through payment of established fees.
The City of Beaumont should upgrade the classification of Beaumont Avenue from Cherry Valley Boulevard to 6th Street as a Major highway.
This roadway is currently classified as a Secondary highway. These classification changes are required with or without the Noble Creek Specific Plan project.

3.0 AREA CONDITIONS
A. Study Area
1. Area of Significant Traffic Impact
The study area includes the following intersections:
Beaumont Avenue (NS) at:
• Cherry Valley Boulevard (EW)
• 14th Street (EW)
• I-10 Freeway WB Ramps - 5th Street (EW)
• I-10 Freeway EB Ramps - 4th Street (EW)
B. Study Area Land Use
1. Existing Land Uses
The site is currently vacant and relatively low traffic generation is currently being generated from the project.
2. Other Development
The analysis by Urban Crossroads, Inc. uses the City of Beaumont Traffic Model with modifications to include the proposed project to forecast buildout traffic impacts.
3-1
C. Site Accessibility
1. Area Roadway System
Exhibit 3-A identifies the existing roadway conditions for study area roadways. The number of through traffic lanes for existing roadways and the existing intersection controls are identified.
The City of Beaumont General Plan Circulation Element is depicted on Exhibit 3-B. Similarly, Exhibit 3-C illustrates the Riverside County General Plan Circulation Element.
2. Traffic Volumes and Conditions
Existing average daily traffic (ADT) on arterial highways throughout the study area are shown on Exhibit 3-D. ADT's are based upon traffic data indicated in the 1999 Traffic Volumes on Califomia State Highways by Caltrans, the Riverside County Traffic Count database and factored up from peak hour counts conducted by Urban Crossroads, Inc., using the following formula for each intersection leg:
PM Peak Hour (Approach Volume + Exit Volume) * 12 = Leg Volume The current technical guide to the evaluation of traffic operations is the 1997 Highway Capacity Manual (HCM) (Transportation Research Board Special Report 209). The 1997 HCM defines level of service as a qualitative measure which describes operational conditions within a traffic stream, generally in terms of such factors as speed and travel time, freedom to maneuver, traffic interruptions, comfort and convenience, and safety. The criteria used to evaluate LOS (Level of Service) conditions vary 3-2

based on the type of roadway and whether the traffic flow is considered interrupted or uninterrupted.
The definitions of level of service for uninterrupted flow (flow unrestrained by the existence of traffic control devices) are:
• LOS "A" represents free flow. Individual users are virtually unaffected by the presence of others in the traffic stream. • LOS "B" is in the range of stable flow, but the presence of other users in the traffic stream begins to be noticeable. Freedom to select desired speeds is relatively unaffected, but there is a slight decline in the freedom to maneuver.
• LOS "C" is in the range of stable flow, but marks the beginning of the range of flow in which the operation of individual users becomes significantly affected by interactions with others in the traffic stream. • LOS "D" represents high -density but stable flow. Speed and freedom to maneuver are severely restricted, and the driver experiences a generally poor level of comfort and convenience. • LOS "E" represents operating conditions at or near the capacity level. All speeds are reduced to a low, but relatively uniform value.
Small increases in flow will cause breakdowns in traffic movement. • LOS "F" is used to define forced or breakdown flow. This condition exists wherever the amount of traffic approaching a point exceeds the amount which can traverse the point. Queues form behind such locations.
3-7
The definitions of level of service for interrupted traffic flow (flow restrained by the existence of traffic signals and other traffic control devices) differ slightly depending on the type of traffic control.
The level of service is typically dependent on the quality of traffic flow at the intersections along a roadway. The 1997 Highway Capacity Manual (HCM) methodology expresses the level of service at an intersection in terms of delay time for the various intersection approaches. The HCM uses different procedures depending on the type of intersection control. The levels of service determined in this study are determined using the HCM methodology.
For signalized intersections, average delay per vehicle is used to determine level of service. Levels of service at signalized study intersections have been evaluated using the HCM intersection analysis program.
The level of services are defined as follows:
LEVEL OF
SERVICE
AVERAGE TOTAL
DELAY PER VEHICLE
(SECONDS)

E
55.01 to 80.00
35.01 to 50.00
F

50.01 and up
3-8
The LOS analysis for signalized intersections has been performed using optimized signal timing. This analysis has included an assumed lost time of three seconds per phase in accordance with 1997 HCM recommended default values. Signal timing optimization has considered pedestrian safety and signal coordination requirements. Appropriate time for pedestrian crossings have also been considered in the signalized intersection analysis.
Saturation flow rates of 1,900 vehicles per hour of green (vphg) have been assumed for all capacity analysis.
Existing peak hour traffic operations have been evaluated for study area intersections. The results of this analysis are summarized in Table 3-1, along with the existing intersection geometrics and traffic control devices at each analysis location. Existing intersection level of service calculations are based upon manual AM and PM peak hour turning movement counts made for Urban Crossroads, Inc. in March, 2001 (see Exhibits 3-E and 3-F). The turning movement counts have accounted for the additional traffic due to the frontage roads at both 4th and 5th Streets. Manual adjustments have been performed to increase volumes at the I-10 ramps to account for conservation of flow and daily traffic variations.
For existing traffic conditions, the study area intersections of Beaumont Avenue at the I-10 westbound and eastbound ramps operate at Level of Service "E" during the peak hours, as shown in Table 3-1. Traffic count worksheets are included in Appendix "A". Existing HCM calculation worksheets are provided in Appendix "B".

1. Trip Generation
Trip generation represents the amount of traffic which is attracted and produced by a development. The traffic generation for the project is based upon the specific land uses which have been planned for the development.
The approximately 332.3 acre project site is assumed to be developed with single-family detached residential and junior high school land uses.
Trip generation rates for this project are shown in Table 4-1. The trip generation rates are based upon data collected by the Institute of Transportation Engineers (ITE).
Both daily and peak -hour trip generation for the proposed project are shown in Table 4-2. The proposed development is projected to generate a total of approximately 10,395 trip -ends per day with 1,091 vehicles per hour during the AM peak hour and 1,102 vehicles per hour during the PM peak hour.
B. Traffic Model
This section of the report describes the operational procedures and data input formats of the model. The subdivision of the modeling area into a representative zone system, and the creation of the roadway network are described. The procedures utilized for trip generation and distribution, and assignment of traffic to the roadway network are discussed.

The computer modeling process consists generally of seven individual but interrelated steps. These are:
• Definition of a traffic analysis zone system;
Compilation of land use data for each of the traffic analysis zones; • Definition of a roadway network to serve the zone system; • Determination of efficient and logical route paths through the network between the individual traffic analysis zones;
• Determination of trip generation within each traffic analysis zone; • Determination of the distribution of trip -ends between the traffic analysis zones for three individual trip purposes; and
Assignment of trips to the individual roadway segments of the overall roadway network.
1. Zone System
To produce a forecast of traffic volumes within the modeling area, traffic must be loaded onto the roadway network in a manner which approximates how real traffic enters and uses the real roadway system. To accomplish this, the Beaumont Traffic Model study area is divided into a traffic analysis zone (TAZ) system as shown on Exhibit 4-A. The project site consists of TAZ 245, 246, 247, 248, 249.

Each TAZ represents the area where traffic is generated (expressed as a number of trip "productions" and "attractions") by the land uses in that TAZ.
During the trip distribution stage of the process, traffic is distributed from each "production" zone to all other zones of the modeling area based on the "attractiveness" of each other zone. In this way, the zones interact with each other. To insure that there is adequate interaction, the zone system must be subdivided into areas which are small enough to accurately represent the distribution process and the manner in which traffic loads to the roadway network.
The study area is tied to the outside world through external zones called cordon stations. Traffic enters and leaves the study area through the cordon stations. In addition, traffic which passes through the study area, but does not interact with it, (termed "through" traffic) is represented as traffic which passes directly from one cordon station to another.
2. Roadway Network
The roadway network generally excludes local level streets, because it is impractical to model traffic at that level of detail. The network is described in the model as a series of roadway links connected at node points. Traffic generated within each internal TAZ is introduced to the roadway network through one or more zone "centroid" connectors. These are fictitious roadway links which connect the zone center (the idealized point of zone trip generation) to the arterial roadway system. In a similar manner, cordon zones have special connectors termed cordon links.
Each roadway link is defined in terms of its link end points (nodes), a unique length and a facility code. The facility codes for the network, which define an initial link speed and capacity, are listed in Table 4-3. The Beaumont 4-6

3. Trip Generation
Trip generation is the process of determining the overall magnitude of travel demand (trip making) within the study area. The trip generation procedure included in the Beaumont Traffic Model is dependent on the analysis time frame under consideration. The build -out trip generation forecasts within the study area are based on projected land uses as contained in the City of Beaumont General Plan Land Use Element (or the most appropriate jurisdiction outside of the City of Beaumont).
The following three trip purposes are used in the Beaumont Traffic Model:
• Home -Work Trips
Other -Work Trips
• Non -Work Trips
The trip -ends for each purpose (and by production/attraction end) have been disaggregated for use by the Beaumont Traffic Model. Trip generation is expressed in terms of "productions" and "attractions". Each trip made in the model has two "trip -ends", a production end and an attraction end. The production trip -ends in the model are related to residential dwelling units for "home -based" trip purposes. Regardless of whether the direction of the trip is from the residence to a shopping location, or from the shopping location to the residence, it is expressed as a home - based production at the residence end of the trip. Retail land uses on the other hand, have no production trip -ends for "home -based" trip purposes; they attract trips made from residential land uses. All residential uses utilize 4-8
