CIT~ OF SAN BERNARDIN'iS - REQ~ST FOR COUNCIL Ai*'ON STAFF REPORT The Negative Declaration for Public Works Project No. 90- 07 was reconunended for adoption by the Environmental Review Conunittee at its meeting of 05-03-90. A 2l-day public review period was afforded from 05-10-90 to 05-30-90. No conunents were received. One special mitigation measure is that an archaeological monitor shall be present during the initial excavation stages, in order that any cultural deposits encountered can be evaluated and appropriate data recovery/protection measures implemented if necessary. We reconunend that the Negative Declaration and Mitigation Moni toring and Reporting Program be adopted and a finding made that the project is consistent with the the General Plan. 6-06-90 75-0264 . ."..-.., ,~ o o :) NOTICE OF PREPARATION OF NEGATIVE DECLARATION OF ENVIRONMENTAL IMPACT THE CITY OF SAN BERNARDINO proposes to adopt a Negative Declaration for the following projects.

The 9radln9 operation will result In temporary Impacts on the physical environment (erosion, dralnage, etc.) as well as the community (dust, noise, etc.). The erosion and dralnage from the project will be controlled and minimized with the use of sandba9s as necessary. Dust will be controlled by frequent waterln9 of soil. compliance with San Bernardino Municipal Code section 8.54 will minimize noise Impacts. Resultant Impacts from the 9radln9 will be InslCjnlflcant.

Only superficial downslope movement of rock or sojl debris or mud flow Is expected, even during an earthquake. In the unlikely event of debris basin failure as a result of a major earth tremor or slope failure, expected risk and damaqe would primarily be dependent upon the amount of water In the basin at time of failure. The basin will fill only If Its outlets become clogqed. To preclude the basin from fllllnq, the outlets shall be cleaned out annually and after each major storm. Potential risk of floodlnq as a result of debris basin failure will be reduced to a level of Insignificance. ~. l.f., and 4.a. c6nstructlon of the debris basin may prevent water from reachlnCj the natural and Intermittent streambed that parallels Chestnut Avenue outside the sixty foot right-of-way.

The project lies within an area of archaeolo9ical concern. Michael K. Lerch and Associates conducted an archaeolo9ical survey and study of the site in Nove.ber, 1989 (Attach.ent C). Froa the study and survey it was concluded that no adverse i.pacts to known cultural resources were expected froa the construction of the Chestnut Stor. Drain. Since the ori9inal study did not address the upper debris basin site, the site was surveyed for potential archaeolo9ical resources on April 25, 1990, and an addendu. to the ori9inal cultural assess.ent was prepared (Attach.ent D). The addendua a9ain concluded that no adverse i.pacts to known cultural resources were expected fro. the construction of the debris basin at the upper site. However, because of the possibility of encounterin9 buried cultural deposits durin9 excavation of the Chestnut Drain Debris Basin, an archaeolo9ical aonitor shall be present durin9 initial excavation stages in order that any such materials encountered can be evaluated and appropriate data recovery/protection aeasures iapleaented if necessary. , ,...-.

LaPre, PhD Robin Bishop November, 1989 Introduction This report was contracted by Michael K. Lerch & Associates to provide the City of San Bernardino Public Works Department with site-specific information on five infrastructure projects in the Verdemont area. The location of these projects is given in Figure 1 and they are described briefly below: 1. Chestnut Avenue Drain underground storm drain undeveloped Chestnut Avenue base of the foothills. constructed at the inlet. This consists of construction of an within the 60' right-of-way of from the Cable Creek crossing to the A 2-3 acre debris basin will be 2. EAlm Avenue ImDrovements. Palm Avenue will be improved with curbs, gutters, sidewalks, and streetlights within the existing right-of-way (88-100'). Improvements are planned for all unfinished segments of Palm Avenue from Kendall Orive to the Muscubiabe Rancho line. 3. EAlm Avenue Dgx Culvert. A box culvert will be constructed at the crossing of Cable Creek by Palm Avenue. 4. EAlm Avenue/Kendall Orive Traffic Sianal. A traffic signal will be installed at the intersection of Palm Avenue and Kendall Drive. 5. Bailev Creek Storm Drain. This project is to construct a concrete trapezoidal channel from the existing channel near the corner of Walnut Avenue and Belmont Avenue along the existing stream channel to the mouth of Bailey Canyon, where a debris basin will be located. The Chestnut Avenue drain, the Bailey Creek drain, and the Palm Avenue box culvert will require permits from the California Department of Fish and Game and the U. S. Army corps of Engineers. These agencies guide development within stream beds, and often require mitigation for adverse impacts to riparian vegetation that is found along stream channels. This report is intended to provide baseline data on the biological resources of these project areas, particularly existing riparian vegetation and habitat values. Suggestions are also provided so that the City can prepare applications for the wetland permits and plan for the expected mitigation that could be imposed as permit conditions. Pf)j ~-O? - ,>-';", ,-... '-' o :) "I",... Xetllods A literature review was conducted to identify any sensitive elements which are known to occur on or in the vicinity of the property. This included consultation with the california Natural Diversity Data Base (Data Base). We also reviewed the earlier report of Pacific Southwest Bioloqical Services (1985) on the Verdemont planninq area, as well as pertinent environmental documents from other development projects in the area. Information included in the San Bernardino National Forest Land and Resource Manaqement Plan (1988) for the Bailey Canyon area was reviewed as well. FOllowinq the literature review, a field survey was performed by Robin Bishop on May 9, 11, 12, 18, and 19, 1989. L. LaPre reviewed all of the project sites on AUqust 20, 1989. Twenty hours were spent walkinq over the sites and all plant and animal species detected were recorded in field notes. Common names are used in the text for all species. Appended to this report is a species inventory for each project site except the siqnalization (Project #4) which provides both scientific and common names. The siqnalization project area was entirely paved, and contained no plants or animals. aesulte The Verdemont area is characterized by alluvial deposits which are dissected streambeds draininq the adjoininq chaparral- covered slopes of the San Bernardino National Forest. The veqetation on the alluvial fans and terraces is in a transition between the coastal saqe scrub communities of lower elevations and the chaparral of the hiqher elevations and steep sloes. The veqetation reflects the lonq-term activities of the Cajon Creek drainaqe, supportinq both elements of the alluvial saqe scrub community and a rather larqe stand of California walnut trees. These noteworthy California native plants reach the eastern edqe of their distribution in the Cajon Pass. The walnut woodland is a declininq nativ~.. plant community (Holland 1986). The walnut treespresent in the Verdemont area are not in a woodland formation, but rather are found as larqe isolated trees on the alluvial bench and as trees and shrubs within the riparian drainaqes. The Riversidian alluvial fan saqe scrub plant community is a species-rich assemblaqe of shrubs typical of both the coastal saqe scrub and chaparral communities, thouqh coastal saqe species are qenerally dominant (Sanders, 1987, citinq Smith). This veqetation formerly covered most of the alluvial slopes in the Los Anqeles basin, but has now been qreatly reduced in extent by urban expansion (Smith, 1980, citinq Hanes). This is the same fate that has befallen the more typical coastal saqe scrub of adjacent foothill slopes and plains: it has been estimated that 2 .C ,....., '-' o ,,--"',\ ...) this community has been reduced in extent by 90t due to urbanization (Sanders, 1987). Most authors have included alluvial" scrllb within their concept of coastal sage scrllb and even Smith agrees that alluvial scrllb is part of the coastal sage scrub "type- (Sanders, 1987). Holland, (1986) includes the community in his inventory of natural communities in California. Because this vegetation association is thought to be in decline, it is designated by the Data Base as a community with highest inventory priorities. Riparian communities occur along drainages and provide plants adapted to temporary or permanent water with the conditions to survive. Riparian vegetation provides high-quality wildlife habitat. Because of the extensive loss of riparian communities in California, the protection of this vegetation is a top priority of the California Department of Fish and Game CDFG). The California Fish and Game Commission has adopted a policy of "no net loss" of wetlands for the state, which includes riparian wetlands. "The riparian communities bordering the streams within the Verdemont area are narrow bands of dense trees and undergrowth. Most of the drainages support a diverse plant community which is high-quality wildlife habitat. The historic vegetation in the Verdemont area has been modified into what is now a degraded community of coastal sage scrub vegetation with scattered walnut trees on the uplands, and remnant strips of good riparian communities along the drainages. The Riversidean alluvial fan sage scrub is only present as a distinot association west of Interstate 15, and none of the rare species known to occur in this community are found near the Phase I infrastructure project area. The walnut woodland, if ever present, has likewise been reduced to scattered older trees, some of which are found within the infrastructure project boundaries. Only the riparian communities appear to have maintained their historic structure and species diversity. The biological resources of the individual infrastructure project sites are dfscussed separately below. Chestnut Avenue Drain Chestnut Avenue is undeveloped along most of its length north of Belmont Avenue. The road right-of-way follows dense rows of Eucalvctus and olive trees, and contains a wide ditch in the centerline. The streamcourse parallels Chestnut Avenue, and does not appear to be part of the sixty foot right-of-way. A large number of riparian trees, mainly sycamore, elderberry, and willow are found in the stream channel that borders the Chestnut Avenue right-Of-way. A dense understory in most places is made up of mulefat, poison oak, squawbush, tarragon, and western raqweed. This riparian vegetation is of high importance as wildlife habitat, contrasting with the 3 - ''''''' I"""'. '-" ~ :) artificial ditch and bordering ornamental tre.s within the road right-Of-way. " The debris basin site contains primarily a disturbed coastal sage scrub plant co_unity, dominated by buckwheat and coastal sagebrush. The stream channel at this location includes a scrub vegetation of mulefat, with about eight smaller sycamore trees. The dry riparian debris basin site is much less well developed than the riparian woodland located downstream. EAlm Avenue Imnrovements No significant biological resources exist within the right- of-way for the planned improvements to Palm Avenue. We estimate that the improvements will result in the removal of one sycamore, one California walnut, several EucalvDtus, and a few olive trees. EAlm Avenue Ilgx CUlvert No siqnificant biological resources are found at the Palm Avenue crossing of Cable Creek, where the box culvert is planned. Cable Creek is channelized and riprapped at this location, and virtually no vegetation exists in the stream channel. Along the borders for 200" in either direction, the plants consist of weedy natives such as Jimson weed and doveweed, along with many undesirable introduced European grasses and weeds. iAlm Avenue/Kendall Drive Traffic sianal The intersection to be signalized is completely disturbed or paved and contains no biological resources. Bailev Creek storm Drain Bailey Creek, where it crosses over the alluvial plain downstream to Walnut Avenue near Belmont Avenue supports a lush and very significant riparian community. At the debris basin site, most trees are in excess of forty feet in height. Wildlife is abundant in and near this stream channel. In addition to sycamores, mulefat, willows, and elderberry, we observed one fifty-foot-tall incense cedar, and four bigcone Douglas fir, all of which appeared ," to be naturally-occurring "washdown" plants from higher elevations. The riparian community is somewhat invaded by tall EucalvDtus, but continues as a strip of dense trees downstream almost the entire way to the junction with the existing concrete trapezoidal channel. Just upstream from the channel is the driest and least significant portion of this creek. Sensitive snecies The computerized search of the Data Base, previous reports from the area, and other materials listed in the references section of this report indicated that four sensitive plants, two sensitive animals, and one natural co_unity have been recorded 4 .c "...... .....I ......,- , ,j '-'" in the vicinity of the Verdemont infrastructure projects. Two other plants, the thread-leaved brodiaea and the San Bernardino owl'. clover, were also reported from the San Bernardino North quad, but these plants are montane species found at higher elevation. and have no suitable habitat near Verdemont. Therefore, they were eliminated from further consideration. . sensitive species are so-called because their populations are declining, they are especially vulnerable to habitat change, or because they have restricted distributions and are therefore uncommon.

Sleneler-boneel spine flower is a small, low-to-the-qround, sprinq-bloominq annual of the buckwheat family. Its preferred habitat is dry sandy benches of washes below 2,000 feet in the coastal saqe scrub or alluvial sage scrub plant communities. Although populations of the slender-horned spineflower range from the San Fernando Valley to the San Bernardino Valley and the Elsinore area, most historic locations have been eliminated by urbanization and river modification for flood control. This extensive loss of habitat has resulted in the, listing of this species as endangered by the State of California and the U. S. Fish 'Wildlife Service. The Data Base reported a population of slender-horned spineflower in Cajon Canyon near Devore, somewhat west of the project sites. No suitable habitat for the slender-horned spineflower exists on the Phase I Verdemont infrastructure sites. All known habitat and occurrences are west of Interstate 15. The Santa Ana River WOOlly-star is a small gray-green shrub of the phlox family with blue flowers. It occurs in alluvial fan sage scrub of the higher flood plain terraces of the Santa Ana River and its tributaries and tends to occupy habitats with little evidence of surface disturbance. The historic range of the Santa Ana River woolly-star spanned approximately sixty river miles from Rancho Santa Ana in Orange County at an elevation of 500 ft. to the the vicinity of Highland in San Bernardino County at 1500 ft. It is currently restricted to several disjunct populations on Lytle Creek and in the flood plain of the Santa Ana River from Redlands to the mouth of the Santa Ana Canyon in San Bernardino County. The total range has been reduced by at least 70\ to about 18 river miles. Human encroachment through intensive use of the flood plain margins for urbanization, flood control structures" ground water recharge facilities, sand and gravel mining, and' farming has further reduced the sui table habitat for the plant by greater than 90\. This extensive loss of habitat has resulted in the recent listing of this species as endangered by the State of Cali fornia and the U.S. Fish & Wildlife Service. The Data Base reported an extirpated location of the Santa Ana River WOOlly-starin the vicinity of Devore. Krantz (1987) reported 16 small woolly-star plants 0.3 mile north of Institution Road on the west side of Cajon Boulevard. The WOOlly-stars at the Sheriff's Training Center site have been studied (Tierra Madre Consultants, 1988) and determined to contain intergrade populations, representing genetic crossing between two subspecies. 8 "C /'"'", 1""'\ V .J ~ All known sites for the Santa Ana River woolly-star are west of the infrastructure projects in Verdemont. No suitable alluvial sage scrub habitat is present on the project sites, and no woolly-star plants were saen. Tha range of the San Diego horned lizard extends from near the coastline eastward through the interior valleys and plains to the slopes of the San Bernardino, San Jacinto, and Santa Rosa Mountains. This species is also known from western San Diego county but is absent from southern California deserts. Preferred habitat consists primarily of flatlands occupied by grassland, coastal sage scrub, sparse chaparral, and occasionally, upper elevations of open, coniferous woodlands. It is rarely found under closed-canopy, evergreen cover. open stretches of sandy soil used for basking, cover, and social behavior, are apparently a critical habitat component. Ants are the primary food of this species although, it will also feed on other insects. Populations of this lizard are declining due to extensive collecting on wildlands and as a result of its habitat being converted to agricultural and urban uses. This lizard has been recently reported from Cajon wash, and is expected to occur in the less-disturbed lands of the Verdemont planning area. This includes the Chestnut Avenue drain and the Bailey Canyon strom drain project areas. Very little is known about the Los ADgele. pocket mou.e. It apparently digs underground burrows and is nocturnal, and is thereflllre not often detected except in trapping surveys. The geographic range is restricted to lower elevations in grassy areas from Burbank to San Bernardino and eastwards to Aquanga in R.i.verside County. Urbanization and cultivation have eliminated much of the habitat for this uncommon rodent. In 1931 there was a report of the Los Angeles pocket mouse from 4.75 miles north of San Bernardino. The records presented by Williams (1986) indicate that this species ranged mainly in the San Bernardino Valley. Therefore, it is not known whether or not the Verdemont~rea would provide suitable habitat, since it appears to lie at the upper elevational edge of the species range. In addition, the probable habitat of this species is grassland or coastal sage scrub, rather than the riparian vegetation found at the least disturbed infrastructure project sites. The most likely locations for this species, if it occurs, are at the edge of the drainages on the Chestnut Avenue and Bailey Canyon drain projects. A focused trapping study would be required to absolutely determine the presence or absence of the Los Angeles pocket mouse. Because of the nearness of the historic record and the fact that some sage scrub habitat is found at the edges of the Bailey Creek and Chestnut Avenue drainages, we believe that a lIIoderate probability exists for occurrence of this rodent. 9 "C 1"'""\ V -:) :J In sUlDlDary, no rare, threat.ned, or .ndanq.red speci.s of plant or animal was found on any of the infrastructure proj act sit.s. . pot.ntial habitat: is available at the Chestnut Street\ drain and Bailey Dreek drain sit.. for two declininq .pecies Of.. wilcUife, which are candidate speci.s for future federal protection under the Endanqered Species Act. DiscussioD One of the proposed infrastructure projects did not contain any native veqetation or wildlife habitat, or any other siqnificant bioloqical features. This project, the signalization of the Palm Avenue/Kendall Drive intersection, is excluded from further discussion of bioloqical resources. The Palm Avenue box culvert lacks bioloqical siqnificance except as a component of the Cabl. Creek stream system, which contains higher resource value upstream and downstream. The Palm Avenue widening improvements affect biological resources only minimally, resulting in the loss of a few native trees. However, the\\ Chestnut Avenue drain project contains significant riparian J vegetation. Three of the five Phase 1 infrastructure projects will require permits from the Department of FiSh and Game under Sections 1601-3 of the Fish and Game Code. These same projects will also probably require permits from the Corps of Engineers, which administers Section 404 of the federal Clean Water Act. Because the Palm Avenue box culvert will not impact riparian habitat of any important biological resources, the permitting for this P..I"oj ect will be ministerial after submittal of the application with fee. The Chestnut Avenue drain and the Bailey Creek storm drain, on the other hand, will require permits from the CDFG and the Corps of Engineers. The permitting requirements and further analysis that might be needed for each of the projects is discussed below, along with recommendations and potential mitigating measures for loss of biological resources. Chestnut Avenue Drain Most of this project appears to lie outside of the blueline stream channel depicted on the USGS map. Therefore, permitting by the Department of Fish and Game and Corps of Enqineers may not be necessary. Less than one acre of existing riparian vegetation will be impacted by construction of a 2-3 acre debris basin at the base of the foothills. However, the debris basin may prevent \ water from reaching the existing native trees in the fomer stream channel. If the debris basin cuts off the flow to the existing natural stream channel, a Streambed Alteration Agreement with the Department of Fish and Game will be required. Although the impact of this diversion is unknown, we would expect: a gradual die-off of the native trees, even without surrounding development. 10 .1'...._, . r" '-" /,,\ V :.) "\".... We recommend that the line of native sycamores, walnuts, andl willow. be retained to the extent possible within any future planned" development adjacent to Chestnut street. The riparian woodland could form a qreenbelt of some sort adjacent to Chestnut street. Hiqher-density development of the non-riparian lands wi th retention of the riparian strip would be preferable to removal of the trees. Construction of the Chestnut Avenue drain will result in the removal of several hundred mature EucalVDtus and olive trees, along with about twenty California sycamores and perhaps one or two California walnuts. These trees should be replaced with plantings of street trees once the Chestnut Avenue improvements are in place. We recommend the use of California sycamore, California walnut, Fremont cottonwoods, white alders, and other native trees for replacement plantings, rather than olives, Eucal VDtus, or other ornamentals. The older neighborhoods of Verdemont have been planted with California sycamores, and the result is a shady street that still provides some wildlife with valuable habitat. ~ Avenue ImDrovements This project has no substantial biological resources, and no mitigation of adverse impacts is required. The project is outside of the jurisdiction of the Department of Fish and Game and the Corps of Engineers. The loss of less than five native trees (California walnut and California sycamore) could be mitigated with the replanting of these same species as street trees lining the sidewalk. ~ Avenue BQx CUlvert No important biological resources would be impacted by this project, so mitigating conditions are not expected to be necessary. Because the size of the stream channel that is being altered is so small, the 1601 and 404 permits required by the Department of Fish and Game and the Corps of Engineers will be mainly a matter of notification to the agencies. EAlm Avenue/kendall Drive Traffic Sianal This project has no biological resources, and no mitiqation of adverse impacts is required. The project is outside of the jurisdiction of the Department of Fish and Game and the Corps of Engineers. Bailev Creek Storm Drain Construction of the Bailey Creek storm drain will present very significant impacts to the biotic environment. We do not believe that the Department of Fish and Game or the Corps of Engineers will issue a permit for the project as proposed. Heavy mitigation in the form of riparian enhancement in other areas is sure to be a condition of approval, it approval can be obtained. 11 . ..- \.. . c :> , ,) We recommend that the city rethink the Bailey Creek drainage plan. -The best location for a debris basin from the biological perspective would be at the inlet of the existing concrete channel. Even here, impacts to the Bailey Creek riparian habitat would be substantial. At all other locations upstream, impacts to the riparian vegetation would be highly significant. We cannot recommend in favor of proceeding with the Bailey Creek storm drain project as proposed. The conversion of the former creek where the concrete channel is now is a classic example of what the Fish and Game Commission is attempting to prevent with its new "no net loss of wetlands" policy. A better plan would preserve the remaining drainage course as a natural greenbelt. This may require reducing the density approved for the surrounding lands so that the developed lots will not be subject to flooding. perhaps a levee could be constructed outside of the riparian zone on either side to protect lands from flooding. Land uses that are compatible with the retention of the riparian strip, such as a golf course or parks, should be considered. Alternative designs and locations for a debris basin might reduce the biological impact. The further downstream the debris basin is placed, the lower will be the biological impacts. At and within the Forest service boundary, the riparian vegetation is especially dense and diverse. The Forest service -is unlikely to approve a drainage plan that disturbs this habitat on their lands, so we recommend that the debris basin be placed downstream. Additional study will be necessary to proceed with the permits required by the Department of Fish and Game and the corps of Engineers. We anticipate that the Corps will insist on a discussion of alternatives, and that they might require a federal Environmental Impact statement to be prepared on the issuance of a permit. If the application is accepted as now envisioned, extensive mitigation will likely be required. In similar cases in the past, permit conditions have included provision of replacement riparia~ acreage. Enhancement of a degraded stream channel at another location with riparian species could mitigate the loss of the existing habitat. Enhancement projects have often been required at a replacement ratio of 1: 1, meaning for every acre of riparian habitat lost, one acre must be enhanced or restored. Purchase of an existing riparian habitat for purposes of protection is also a mitigation possibility. In cases like this, purchase of habitat has been accomplished at a ratio of 3:1 or greater, even of up to 10: 1 on an acre-for-acre basis, depending on the value of the riparian habitat being lost. 12 . ,~.

D street, 3rd Floor San Bernardino, CA 92418 Dear Mr: Grubb.: I have completed a trappinq study at the Chestnut Avenue Storm Drain, an infrastructure project located in the Verdemont area of the City of San Bernardino. This study focused on determining the pre.ence or absence of the Lo. Angeles pocket mouse (P.ro~nathu. 10naimembris brevina.u.), also called the .hort-no.ed pocket mouse. ~hi. rodent is thought to be declining due to 10.. of habitat, and it haa been de.ignated a. a candidate species for li.tinq as threatened or endangered by the U. S. Fi.h , wildlife Service. On the evening of April 21, 1990, my assistant Kelly Campbell and I inspected the alignment of the proposed storm drain from the Cable Creek wash to the proposed debris basin site at the base of the foothills. We identified the suitable habitat for the pocket mouse, then ..t 160 Sherman live trap. along the .torm drain alignment. ~heee were placed in tour rowa spaced ten meter. apart. The traps were .et mainly between Irvlnqton Avenue and Pennsylvania Avenue. We returned at sunrise on the morning of April 22, 1990 to check the traps. Only five rodents were captured. None ot these were pocket mlce. ~he four deer mice and one California mou.e captured are common residents of sage scrub and chaparral habitats in southern California.

MANAGEMENT SUMKARY In Auqust 1989, an archaeo1oqical survey of five public works infrastructure improvements in the Verdemont area of the City of San Bernardino was conducted by Michael K. Lerch , Associates at the request of the City Public Works Department, in order to provide information for environmental assessments for the proposed projects. Because the projects will require actions by local, state, and federal aqencies, the study provides the necessary information for compliance with the California Environmental Quality Act, Section 106 of the National Historic Preservation Act, and the National Environmental Policy Act (NEPA) . The archaeoloqical survey was preceded by a records check with the Archaeoloqical Information center, San Bernardino County Museum, and a review of relevant literature and archival sources. The five proposed projects are known as: 1) Chestnut Avenue storm Drain: 2) Palm Avenue Improvements: 3) Palm Avenue/Cable Creek Box Culvert: 4) Palm Avenue/Kendall Drive Traffic Siqnal: and 5) Bailey Creek storm Drain. All five projects are located in the Verdemont Planninq Area in the northwestern portion of the City of San Bernardino, California. The results of the records check, archival and literature review, and archaeoloqical survey were neqative. No impacts to historic or prehistoric cultural resources eliqible or potentially eliqible for listinq in the National Reqister of Historic Places are anticipated from construction of any of the five Verdemont infrastructure improvements, and no further cultural resources investiqations are recommended. However, because of the possibility of encounterinq buried cultural deposits durinq. excavation for the Bailey Creek Storm Drain, it is recommended that an archaeoloqical monitor be present durinq initial excavation for that project in order that any such materials encountered can be evaluated and appropriate data recovery/ protection measuf.~s implemented if necessary. i - - "I",... /".' '- -, , , '....,I ') . , DI'l'RODUCTJ:OIf This "report documents a cultural resources assessment of five public works infrastructure improvements in the verdemont Planning Area of the City of San Bernardino, California. The study was conducted by Michael K. Lerch , Associates at the request of the City Public Works Department, in order to provide information for environmental assessments for the proposed projects. Because the projects will require actions by local, state, and federal agencies, the study provides the necessary information for compliance with the California Environmental Quality Act, Section 106 of the National Historic Preservation Act, and the National Environmental Policy Act (NEPA). The field survey of the projects was conducted on Auqust 2-4, 1989, by Michael K. Lerch (see Appendix A), who also authored this report. The five proposed projects are known as: 1) Chestnut Avenue Storm Drain; 2) Palm Avenue Improvements; 3) Palm Avenue/Cable Creek Box culvert; 4) Palm Avenue/Kendall Drive Traffic signal; and 5) Bailey Creek storm Drain. All five projects are located in the verdemont Planning Area in the northwestern portion of the city of San Bernardino, california. More specifically, they are situated in the extreme southeastern corner of Section 36, T2N, R5W; Section 1 (projected), TIN, R5W; and Section 6 (projected), T1N, R4W; SBBM, as shown on the USGS San Bernardino North 7.5' topographic quadrangle, 1967 edition, photorevised 1980 (Fig. 1). The project descriptions are as follows, with numbers and names corresponding to locations shown in Fiqure 1: 1. Chestnut Avenue Storm Drain. This project will consist of the construction of an underground storm drain from the National Forest boundary to Cable Creek within the 60-foot right-of-way of Chestnut Avenue. A 2-3 acre debris basin will be constructed at the inlet on the northern end of the drain. The approximate length of the storm drain will be 5,000 feet.' For purposes of this study the area of potential environmental impact was considered to be 100 feet (30 meters) wide and one mile long. 2. Palm Avenue ImDrovements. This project involves widening of Palm Avenue to its full right-of-way width, which varies from 88 to 100 feet, from the boundary of Muscubiabe Rancho on the north to Kendall Drive on the south, a distance of one mile. CUrbs, qutters, sidewalks, and street lights will be constucted in those portion of Palm Avenue where they are currently lacking. Full right-of-way improvements have already been made adjacent to some recent developments, which amount to approximately 10' of the total length of the project. For purposes of this study the area of potential environmental impact was considered to be 150 feet (45 meters) wide and one mile long. 1 - "".-~. c ,,,",, '....,I """,\ -# ... - )f"1O ... .... .. .... -~ ~ '-" '- '''') . --.:.:.~ Palm Avenue/Cable Creek Box o.u vert " Pe'col~tlon '.... ------ 4.

This project is a box culvert to be constructed at the intersection of Palm Avenue and Cable Creek. It will involve qradinq within the existing' Palm Avenue and Cable Creek riqhts-of-way for a distance of up to 200 feet (60 meters) upstream and downstream from Palm Avenue. Palm Avenue/Kendall Drive Traffic sianal. This project will consist of the installation of a traffic siqnal at the intersection of Palm Avenue and Kendall Drive. All work will be conducted within the existinq riqhts-of-way and will involve the installation of poles, underqround conduits, and conductors at the intersection. Bailev Creek storm Drain. This project involves the construction of a storm drain from a location a short distance inside the boundary of the San Bernardino National Forest downstream to connect with the existinq channel near the intersection of Walnut Avenue and Belmont Avenue, a distance of approximately 5,000 feet. A 2-3 acre debris basin will be constructed at the inlet of the channel. The riqht-of-way for the open trapezoidal channel is 60 feet wide. For purposes of this study the area of potential environmental impact was considered to be 150 feet (45 meters) wide and one mile lonq. Any cultural resources located within the area of potential envi~onmental impact of any of the five projects would be subject to direct adverse impacts. 5. ENVIRONMENTAL SETTING The five infrastructure projects are located on an alluvial slope at the base of the San Bernardino Mountains, with elevations in the area of the projects ranqinq from 1,700 to 2,200 feet above mean sea level. A natural source of fresh water is present in Bailey Creek, a perennial stream which supports a lush riparian plant community. A riparian community is also present alonq the Chestnut Avenue drainaqe, although the stream is intermittent. Between the two drainages, an alluvial sage scrub plant community is present. Soils in the project area are primarily well-drained granitic alluvium. Lithic materials in the area are limited to stream cobbles and occasional qranitic outcrops, which would have been suitable for aboriginal manufacture of ground stone implements. Stone materials that could be utilized for flaked stone implements were not observed during the field survey. The current land use of the project area is rural/urban residential in the process of converting to urban densities. Historically, the area has been used for qrazing and low-density residential purposes and open space. "" 3 . r" ''"-' /.. .... .:) ,) ...... OBJECTZVES OP THE STUDY The Clbjective. of this study were to identify, record, and evaluate the significance of all historic and prehistoric cultural resources located within and immediately adjacent to the project: location.. The study addresses historic structures older than 45 years, historic archaeological resources older than 100 years, and all prehistoric archaeoloqical resources. Signifi- cance was to be determined with reference to criteria for eligibility for listing in the National Register of Historic Place. (36 CFR 60.4). These criteria may also be used for determining whether a resources is "important" as defined in CEQA Appendix K. METHODS OP DATA COLLECTION Prior to the fieldwork portion of the study, an archaeological records check for previously recorded sites and surveyed areas was conducted at the San Bernardino county Archaeological Information Center, located at the San Bernardino County Museum, Redlands (see Appendix B). Available archaeol~gical, ethnographic, and historical literature was reviewed in order that known or expected site types for the region could be anticipated and accurately identified during the field survey. Other sources consulted included the National Reaister of Historic Places (USOI 1979), California Inventorv of Historic Resources (OPR 1976), and California Historical Landmarks (OPR 1982). Archival records reviewed included the US Government Land Office plat map of Rancho Muscupiabe, surveyed by Henry Hancock in 1867, the USGS San Bernardino 1901 15 I quadrangle (based on surveys conducted in 1893-1894), and the US Army Corps of Engineers San Bernardino 1942 15' quadrangle (based on surveys conducted in 1940-1941), on file at the San Bernardino County Archaeological Information Center, San Bernardino County Museum, Redlands. In addition to the above historic maps, various other local history sources pertinent to the area which were provided by the Information Center also were reviewed. An intensive cultural resources inventory potential environmental impact for all conducted by the author on August 3-4, 1989. are described as follows, for each project: 1) A transect spaced approximately 30 feet (10 meters) was walked on each side of the current road alignment for the entire length of the project and parallel transects spaced approximately 10 meters apart were walked in a northwest/ southeast direction over an area of approximately 5 acres where the debris basin is proposed; of the areas five projects Field methods of was used 4 ,';" '"", 3) 4) 5) .......,.,.. ) f..'.... --- '-" 2) A radius of approximately 300 feet (90 meters) was walked around the entire intersection of Palm Avenue and Kendall Drive, including the parallel section of Cable Creek: Same as 2), above: The entire length of the project was slowly driven, and a transect was then walked along the margins of the road approximately 10 meters from the edge of pavement in all locations that have not yet been improved: Two transects were walked on each side of the natural stream channel from the mouth of the canyon to the existing concrete storm drain at its upper end near the intersection of Walnut Avenue and Belmont Avenue. One transect was at the edge of the bank: the other was approximately 10 meters away from the streambank. This project received extra scrutiny because it appeared to be potentially sensitive for prehistoric cultural resources due to its environmental context at the mouth of a canyon adjacent to a natural source of fresh water. In all cases, transects occasionally varied to a zig-zag pattern, with numerous intuitive deviations to adjacent areas to inspect features such as rock outcrops, vegetational associations, depressions, and any debris (refuse) that could have historic significance. Field position was determined with reference to the DSGS topographic quadrangle for the area and with reference to name streets shown in the 1989 Thomas Brothers Guide for San Bernardino County. For the most part, ground visibility for all the projects was fair to excellent. Vegetation partially obscuring ground visibility was heaviest along the upper reaches of Bailey Creek. Some recent trash dumping was noted at the lower end of Bailey Creek and at various locations along the Chestnut Avenue drain. Many of the fields on the mar-qins of both Chestnut Avenue and Palm Avenue had been disced, presumably for weed control. Fieldwork was limited to surface observations--no subsurface testing was attempted. EXISTING DATA AND LITERATURE REVIEW CUltural Background The prehistory of the project region has been reviewed by Altshcul, Rose, and Lerch (1984), who summarized the two primary cultural chronologies relevant to the area (Wallace 1955: Warren 1968) in comparison with numerous refinements and revisions by various authors and a consideration of the paleoenvironmental and geomorphic history of the region. 5 r' o\"., r-..... ,,"',> :) - '-" The general pattern of cultural development in the region i. one of early hunting culture. beginning more than 8,000 year. ago, followed by Archaic Stage populations that emphasized plant food resource. for .ubsistence, and ultimately the development of a generalized hunting and gathering way of life. The latter pattern per.isted into historic times and characterized the lifeway of the ethnographic inhabitants of the region, the Serrano Indians. The Serrano were hunters and gatherers who utilized both large and small game, as well as numerous plant resources, for food. Large game such as deer and pronghorn were hunted with bow and arrows, while smaller animals such as rabbits and various rodent. were taken with throwing sticks, nets, and snares. Acorns from several species of oak formed the staple of the diet, supplemented by seeds such as chia, and roots, tubers, and greens. The settlement pattern of the Serrano consisted of permanent villages located in proximity to reliable sources of water, and within range of a variety of floral and faunal food resources, which were exploited from temporary camp locations surrounding the main village. More detailed information on the lifeways of the Serrano may be found in Benedict (1924), Kroeber (1925:611-619) and Bean and Smith (1978), among other sources. Historic use of the project area began during the Spanish Mission period, with the earliest reference to the project region being the result of an expedition by Pedro Fages in 1772 which passed through Cajon Pass. Subsequent passages through area were recorded by Garces in 1776, by Zalvidea in 1806, by Nuez in 1819, and by Jedediah Smith in 1826. Following secularization of the Spanish missions in 1834, the project area was granted to Michael 'White as Rancho Muscupiabe in 1843. The project area saw use in the l850s and for the rest of the eighteenth century as a haul route for lumber from the mountains via the Devil Canyon Toll Road, which was located just east of the project area (Beattie and Beattie 1951: Altschul, Rose, and Lerch 1984:65-77). During this century the area has primarily been used for rural residential and agricultural purposes. Records Check The archaeological records check conducted for this study by the Archaeological Information Center, San Bernardino County Museum, indicated that a portion of the lower part of the Bailey Creek Storm Drain had been included in previous surveys, and that a previous survey for a 10-acre housing tract abutted Palm Avenue. However, no previous archaeological investigation that included all of the five project areas of potential impact had been conducted, and no previously recorded archaeological or historic sites were, located within the project rights-of-way. One previously recorded historic resource, P-107l-24-H, a cistern, is located adjacent to Plam Avenue, outside the disturbance area. 6 .r ......... "''' 8 ') - Archival Research The principal reason for reviewing the various historic maps of the project area was to determine whether any historic structures or historic archaeological resources might be present on or adjacent to the project route. None of the historic maps researched depicted any structures or other cultural features in or immediately adjacent to the project areas of disturbance, although a number of potential historic resources are depicted in th~ general vicinity of the projects. RESULTS OF '!'HE STUDY The results of the records checks, literature and archival review, and field survey of the project sites were negative. No prehistoric or historic cultural resources were observed in or immediately adjacent to any of the project areas of potential impact. Although no surface evidence was observed, buried prehistoric f archaeological resources are considered a possibility in the y/ upper portions of the Bailey Creek Storm Drain project. Altschul, Rose, and Lerch (1984:12) noted that the present ground surfaces in much of San Bernardino Valley are dynamic features, and that archaeological sites of any antiquity along the tributaries of the Santa Ana River are probably buried. The potential for buried archaeological resources to be encountered in toe upper Bailey Creek area is considered moderate due to ther- environemtnal context at the mouth of a canyon and the proximity of a source of natural fresh water. POTENTIAL PROJECT IMPACTS Due to the negative results of the study as noted above, no adverse impacts to known cultural resources eligible or potentially eligible for listing in the National Register of Historic Places are anticipated from construction of the five public works infrastructure improvements in the Verdemont Planning Area, Assessment District 1987. In the event that subsurface cultural deposits with no surface evidence are present in the Bailey Creek area, they could be subject to adverse impacts. Any buried cultural resources located within the proposed right-of-way would be impacted. RECOMMENDED MITIGATION MEASURES No further preconstruct ion archaeological investigation is warranted for the five infrastructure projects. However, it is recommended that an archaeological monitor should be present~ xl during construction excavation of the Bailey Creek Storm Drain,l~ so that in the event subsurface cultural materials are encountered, such materials can be evaluated and appropriate data 7 . ;r'-- 0'-' - " .... .-- :) ) recovery/protection measures implemented if necessary. If this recommended measure is implemented, it can be concluded that none of the proposed projects will have an adverse effect on "important" cultural resources as defined by CEQA Appendix X, or on properties eliqible or potentially eliqible for listinq in the National Reqister of Historic Places, as defined in 36 en 60.4. 8 '.C r'" '-' .:) ) I I REFERENCES Jeffrey H., Martin R.

DDGBHBJlT 81D11mRY This report is an addendUIII to the cultural resources assessment of five public works infrastructure improv_ents in the Verd_ont Planning Area of the city of San Bernardino conducted by Michael K. Lerch , Associates at the request of the city Public Works Department (Lerch 1989). After the original study was completed; the proposed location of the debris basin for the Chestnut Drain project was relocated, which necessitated additional field survey of the new location. The new location for the debris basin is at the mouth of Meacham Canyon, approximately 1,500 feet north of the originally planned location. The archaeoloqical records check and literature review for the area were updated, and the new debris basin location was surveyed for cultural resources by the author on April 25, 1990. The results of the updated records check, archival and literature review, and archaeoloqical survey of the revised Chestnut Drain Debris Basin were negative. No impacts to historic or prehistoric cultural resources eligible or potentially eligible for listing in the National Register of Historic Places are a~ticipated froll construction of the basin in its new location or froll the extension of the route of the drain to the new location. However, because of the possibility of encountering buried cultural deposits during excavation for the Chestnut Drain Debris Basin, it is recommended that an archaeoloqicalllonitor be present during initial excavation for th~t project in order that any such lIaterials encountered can be evaluated and appropriate data recovery/protection measures implemented if necessary. i ; ,..... ',- 1'""'.. '-' - v ,) :EIl'.rJlODOCT:EOII This report is an addendum to a cultural resources assessment originally prepared for five public works infrastructure improve- ment. in the Verd_ont Planning Area of the city of San Bernardino, California (Lerch 1989). One of those five projects, the Chestnut Drain, has been redesiqned since the original survey was completed. The debris basin at the head of the Chestnut Drain has been moved approximately 1,500 feet north of its original location. This addenda reports the results of an archaeoloqical survey of the new debris basin location and of an additional seqment of the Chestnut Drain which will run from the previous debris basin location to the revised location. The additional study was conducted by Michael It. Lerch' Associates at the request of the City Public Works Department. The field survey of the new debris basin location was conducted on April 25, 1990, by Michael It. Lerch, who also authored this addendum. The new location of the Chestnut Drain Debris Basin is shown is Fiqure 1, along with the locations of the previously reviewed projects and the original location of the Chestnut Basin. The specific location of the new basin location is described as HE l& of the SE l& of the SW l& of Section 36, T2N, R5W; SBBM, as shown on the USGS San Bernardino North 7.5' topoqraphic quadrangle, 1967 edition, photorevised 1980 (Fig. 1). The area of potential environmental impact and the area surveyed for the debris basin encompasses approximately 10 acres. As with the previous study, the area of potential impact for the additional 1,500t feet of storm drain was considered to be 100 feet (30 meters) wide. BACDOtI1ID IIIPORMAT:EOII The reader is referred to the original cultural resource assessment to which this report is an addendum for information on the environ- mental setting, objectives, methods of data collection, and cultural background. The archaeoloqical records check conducted for the earlier study was updated by the author on April 11, 1990. No new information relevant to the Chestnut Basin had been added to the records since the previous records check conducted on July 21, 1989. Field methods during the archaeoloqical survey were the sl!l.llle as used in the earlier study. Parallel transects were walked on each side of the centerline of the extension of the storm drain from the SE corner of Section 36 to the mouth of Meacham Canyon, and the entire 10-acre area of the debris basin and adjoining areas was walked with parallel transects spaced 10 meters or less apart, generally following contour lines. 1 - ',r"..' ,....."'\ ~ .""'"

'- ".., ...,i DSULTS 01' TD STUDY The results of the updated records cheek, literature and archival review, and field survey of the revised location of the Chestnut Basin were neqative. No prehistoric or historic cultural resources were observed in or immediately adjacent to the project area of potential impact. Although no surface evidence was observed, buried prehistoric archaeolO9ical resources are considered a possibility in the vicinity of the debris basin, as was previously noted with respect to the Bailey Creek storm Drain project. Present ground surfaces in much of San Bernardino Valley are dynamic features, and archaeo- lO9ical sites of any antiquity along the tributaries of the Santa Ana River are probably buried. The potential for buried archaeo- lO9ical resources to be encountered at the location of the Chestnut Basin is considered moderate due to the environmental context at the mouth of Meacham Canyon and the proximity of a source of natural fresh water. POTENTIAL PROJECT IMPACTS Due to the neqati ve results of the study as noted above, no adverse impacts to known cultural resources eligible or potentially- eligible for listing in the National Register of Historic Places are anticipated from construction of the Chestnut Debris Basin in its new location. In the event that subsurface cultural deposits with no surface evidence are present in the Meacham Canyon area, they could be subject to adverse impacts. Any buried cultural resources located within the proposed basin or storm drain right- of-way would be impacted. DCOKIIEIlDBD MITIGATION KBASURBS No further preconstruction archaeological investigation is war- ranted for the Chestnut Drain project. However, it is recommended that an archaeological monitor should be present during initial construction excavation of the debris basin, so that in the event subsurface cultural materials are encountered, such materials can be evaluated and appropriate data recovery/protection measures implemented if necessary. If this recommended measure is implemented, it can be concluded that none of the proposed projects will have an adverse effect on "important" cultural resources as defined by CEQA Appendix X, or on properties eligible or potentially eligible for listing in the National Register of Historic Places, as defined in 36 CPR 60.4. 3 ,.,- 'I".., "...., '-' o " ,..", UPBUBca Lerch, Michael K. 1989'CUltural Resources Assessment of Five Public Works Infrastructure Improvements, Verdemont Area Assessment District '987, City of San Bernardino, California.
